CANADIAN NATURAL RESOURCES LIMITED
Cdn$4,000,000,000

97,560,975 Common Shares

---

           Shell Canada Energy ("SCE"), Shell Canada Resources ("SCR") and Shell Gas B.V. ("SG") or any of their permitted transferees or assignees (collectively, the "Selling Shareholders") may offer for sale, from time to time, in aggregate up to 97,560,975 common shares (the "Common Shares") of Canadian Natural Resources Limited representing in aggregate up to Cdn$4,000,000,000 (or the equivalent thereof in other currencies or currency units based on the applicable exchange rate at the time of the distribution) of Common Shares, in one or more distributions, during the 25 month period that this prospectus (including any amendments hereto) remains valid. References in this prospectus to "Selling Shareholders" shall include any such affiliates of SCE, SCR and SG and any other permitted transferees under the Registration Rights Agreement (as defined below). See "Selling Shareholders" and "Plan of Distribution".

           The specific terms of any distribution of Common Shares will be set forth in one or more prospectus supplements, including the number of Common Shares to be distributed, the issue price (in the event the distribution is a fixed price distribution) and any other terms specific to the Common Shares being distributed. Prospective purchasers of Common Shares should read this prospectus and any applicable prospectus supplement before they invest in or otherwise acquire any Common Shares.

---

           We are permitted, under the multijurisdictional disclosure system adopted by the United States and the provinces of Canada, to prepare this prospectus in accordance with Canadian disclosure requirements, which are different from those of the United States. We prepare our financial statements in accordance with International Financial Reporting Standards ("IFRS"), as issued by the International Accounting Standards Board ("IASB"), and they are subject to Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (U.S.). As a result, the financial statements included or incorporated by reference in this prospectus and any applicable prospectus supplement may not be comparable to financial statements of United States companies.

           Certain data on oil and gas reserves included or incorporated by reference in this prospectus and any applicable prospectus supplement has been prepared in accordance with Canadian disclosure standards, which are not comparable in all respects to United States disclosure standards. See "Note Regarding Reserves Disclosure".

           Owning the Common Shares may subject you to tax consequences both in the United States and Canada. This prospectus or any applicable prospectus supplement may not describe these tax consequences fully. You should read the tax discussion in any applicable prospectus supplement and consult with your tax adviser. See "Certain Income Tax Considerations".

           Your ability to enforce civil liabilities under the United States federal securities laws may be affected adversely because we are incorporated in Alberta, some of our officers and directors and some of the experts named in this prospectus are Canadian residents, and most of our assets and all or most of the assets of our officers and directors and the experts are located outside the United States. See "Enforceability of Civil Liabilities".

           Neither the United States Securities and Exchange Commission (the "SEC") nor any state or provincial securities commission or similar authority has approved or disapproved of the Common Shares or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

           All shelf information permitted under applicable law to be omitted from this prospectus will be contained in one or more prospectus supplements that will be delivered to purchasers together with this prospectus. Each prospectus supplement will be incorporated by reference into this prospectus for the purposes of securities legislation as of the date of the prospectus supplement and only for the purposes of the distribution of the Common Shares to which the prospectus supplement pertains.

           The Common Shares may be distributed to or through underwriters, directly pursuant to applicable statutory exemptions or discretionary exemptions from registration, or through agents designated by the Selling Shareholders from time to time. Each prospectus supplement will identify the underwriter or agent, if any, engaged in connection with the distribution of the Common Shares and will set forth the terms of the distribution of the Common Shares, including the net proceeds to the Selling Shareholder(s) and the portion of expenses borne by the Selling Shareholder(s) and/or the Company, and, to the extent applicable, any fees, discounts or any other compensation payable to underwriters or agents, if applicable, and any other material terms. If offered on a non-fixed price basis, Common Shares may be offered at market prices prevailing at the time of sale or at prices to be negotiated with purchasers at the time of sale, which prices may vary as between purchasers and during the period of distribution. If Common Shares are offered on a non-fixed price basis, the underwriters' or agents' compensation will be increased or decreased by the amount by which the aggregate price paid for Common Shares by the purchasers exceeds or is less than the gross proceeds paid by the underwriters or agents to us. See "Plan of Distribution".

           To the extent by applicable law, in connection with any distribution of Common Share (unless otherwise specified in a prospectus supplement) any underwriters or agents, when purchasing as principal, may over-allot or effect transactions intended to fix or stabilize or maintain the market price of the Common Shares at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be interrupted or discontinued at any time. See "Plan of Distribution".

           The Common Shares are listed and posted for trading on the Toronto Stock Exchange (the "TSX") and the New York Stock Exchange ("NYSE") under the symbol CNQ. On July 26, 2017, the last completed trading day prior to the date of this prospectus, the closing price of the Common Shares on the TSX and NYSE was $38.31 and US$30.79 per Common Share, respectively.

           An investment in the Common Shares is subject to certain risks that should be considered by prospective purchasers of Common Shares. It is important for prospective purchasers of Common Shares to consider the particular risk factors that may affect the securities and industry in which it is investing. Prospective purchasers should carefully consider the risks described under the heading "Risk Factors" and the risks identified in the documents incorporated by reference in this prospectus and the applicable prospectus supplement prior to making an investment in the Common Shares.

           Our head, principal and registered office is located at 2100, 855—2nd Street S.W., Calgary, Alberta, Canada T2P 4J8.

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

        In this prospectus and any applicable prospectus supplement, all capitalized terms and acronyms used and not otherwise defined have the meanings provided in the prospectus and any applicable prospectus supplement. Unless otherwise specified or the context otherwise requires, all references in this prospectus to "Canadian Natural", the "Company", "we", "us", and "our" mean Canadian Natural Resources Limited and its subsidiaries, partnerships and, where applicable, interests in other entities.

        Unless otherwise specified or the context otherwise requires, in this prospectus, in any applicable prospectus supplement and in documents incorporated by reference in this prospectus and any applicable prospectus supplement, all dollar amounts are expressed in Canadian dollars, and references to "dollars", "Cdn$" or "$" are to Canadian dollars and all references to "US$" are to United States dollars.

        Our financial statements incorporated by reference in this prospectus and any applicable prospectus supplement are prepared in accordance with IFRS, as issued by the IASB, and they are subject to Canadian generally accepted accounting standards and the standards of the Public Company Accounting Oversight Board (U.S.).

        Canadian Natural has filed with the SEC under the United States Securities Act of 1933, as amended (the "1933 Act") a registration statement on Form F-10 relating to the offering of the Common Shares, of which this prospectus forms part. This prospectus does not contain all of the information set forth in such registration statement, certain items of which are contained in the exhibits to the registration statement as permitted or required by the rules and regulations of the SEC. Items of

Table of Contents

information omitted from this prospectus but contained in the registration statement will be available on the SEC's website at www.sec.gov. You may refer to the registration statement and the exhibits to the registration statement for further information with respect to us and the Common Shares.

        Information on or connected to our website, even if referred to in a document incorporated by reference herein, does not constitute part of this prospectus.

ENFORCEABILITY OF CIVIL LIABILITIES

        We are a corporation incorporated under and governed by the Business Corporations Act (Alberta). Some of our officers and directors and some of the experts named in this prospectus are Canadian residents, and most of our assets and all or most of the assets of our officers and directors and the experts are located outside the United States. We have appointed an agent for service of process in the United States, but it may be difficult for holders of Common Shares who reside in the United States to effect service within the United States upon those directors, officers and experts who are not residents of the United States. It may also be difficult for holders of Common Shares who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil liability and the civil liability of our directors and officers and experts under the United States federal securities laws. We have been advised by our Canadian counsel, Bennett Jones LLP, that a judgment of a United States court predicated solely upon civil liability under U.S. federal securities laws would probably be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. We have also been advised by Bennett Jones LLP, however, that there is a substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon U.S. federal securities laws.

        We filed with the SEC, concurrently with our registration statement on Form F-10 of which this prospectus forms a part, an appointment of agent for service of process and undertaking on Form F-X. Under the Form F-X, we appointed CT Corporation System as our agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC and any civil suit or action brought against or involving us in a United States court arising out of or related to or concerning the offering of Common Shares under this prospectus.

FORWARD-LOOKING STATEMENTS

        Certain statements contained in this prospectus and any applicable prospectus supplement, and in the documents incorporated by reference herein and therein, may contain or incorporate by reference "forward-looking information" and "forward-looking statements" (collectively referred to herein as "forward-looking statements") within the meaning of applicable securities legislation, including the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by the words "believe", "anticipate", "expect", "plan", "estimate", "target", "continue", "could", "intend", "may", "potential", "predict", "should", "will", "objective", "project", "forecast", "goal", "guidance", "outlook", "effort", "seeks", "schedule", "proposed" or expressions of a similar nature, suggesting future outcome or statements regarding an outlook. Disclosure related to expected future commodity pricing; forecast or anticipated production volumes; royalties; operating costs; capital expenditures; income tax expenses and other guidance provided throughout this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein or therein constitute forward-looking statements. Disclosure of plans relating to and expected results of existing and future developments, including but not limited to the Horizon Oil Sands operations and future expansions, the Athabasca Oil Sands Project and the pro forma financial, operating and reserves information relating thereto, Primrose thermal projects, Pelican Lake water and polymer flood project, the Kirby Thermal Oil Sands Project, the construction and future operations of the North West Redwater bitumen upgrader and refinery, and construction by third parties of new or expansion of

existing pipeline capacity or other means of transportation of bitumen, crude oil, natural gas or synthetic crude oil upon which we may be reliant to transport our products to market also constitute forward-looking statements. This forward-looking information is based on annual budgets and multi-year forecasts, and is reviewed and revised throughout the year as necessary in the context of targeted financial ratios, project returns, product pricing expectations and balance in project risk and time horizons. These statements are not guarantees of future performance and are subject to certain risks. The reader should not place undue reliance on these forward-looking statements as there can be no assurances that the plans, initiatives or expectations upon which they are based will occur.

        In addition, statements relating to "reserves" are deemed to be forward-looking statements as they involve the implied assessment based on certain estimates and assumptions that the reserves described can be profitably produced in the future. There are numerous uncertainties inherent in estimating quantities of proved and proved plus probable crude oil, natural gas and NGLs reserves and in projecting future rates of production and the timing of development expenditures. The total amount or timing of actual future production may vary significantly from reserve and production estimates.

        The forward-looking statements are based on current expectations, estimates and projections about us and the industry in which we operate, which speak only as of the date such statements were made or as of the date of the report or document in which they are contained, and are subject to known and unknown risks and uncertainties that could cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such risks and uncertainties include, among others: the ability to successfully integrate the assets acquired pursuant to the Acquisitions (as defined herein) and the employees associated with such assets; future use and development of technology; the ability to implement new technology necessary to efficiently and effectively operate the assets acquired pursuant to the Acquisitions; the ability to achieve the expected environmental impacts from the assets acquired pursuant to the Acquisitions; general economic and business conditions which will, among other things, impact demand for and market prices of our products; volatility of and assumptions regarding crude oil and natural gas prices; fluctuations in currency and interest rates; assumptions on which our current guidance is based; economic conditions in the countries and regions in which we conduct business; political uncertainty, including actions of or against terrorists, insurgent groups or other conflict including conflict between states; industry capacity; our ability to implement our business strategy, including exploration and development activities; impact of competition; our defense of lawsuits; availability and cost of seismic, drilling and other equipment; our ability to complete capital programs; our ability to secure adequate transportation for our products; unexpected disruptions or delays in the resumption of the mining, extracting or upgrading of our bitumen products; potential delays or changes in plans with respect to exploration or development projects or capital expenditures; our ability to attract the necessary labor required to build our thermal and oil sands mining projects; operating hazards and other difficulties inherent in the exploration for and production and sale of crude oil and natural gas and in mining, extracting or upgrading bitumen products; availability and cost of financing; our success of exploration and development activities and ability to replace and expand crude oil and natural gas reserves; timing and success of integrating the business and operations of acquired companies and assets, including those acquired pursuant to the Acquisitions; production levels; imprecision of reserve estimates and estimates of recoverable quantities of crude oil, natural gas and NGLs not currently classified as proved; actions by governmental authorities; government regulations and the expenditures required to comply with them (especially safety and environmental laws and regulations and the impact of climate change initiatives on capital and operating costs); asset retirement obligations; the adequacy of our provision for taxes; and other circumstances affecting revenues and expenses.

        Our operations have been, and in the future may be, affected by political developments and by federal, provincial and local laws and regulations such as restrictions on production, changes in taxes,

Table of Contents

royalties and other amounts payable to governments or governmental agencies, price or gathering rate controls and environmental protection regulations. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in the forward-looking statements. The impact of any one factor on a particular forward-looking statement is not determinable with certainty as such factors are dependent upon other factors, and our course of action would depend upon our assessment of the future considering all information then available.

        We caution that the foregoing list of important factors is not exhaustive. Unpredictable or unknown factors not discussed in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein or therein, could also have material adverse effects on forward-looking statements. Although we believe that the expectations conveyed by the forward-looking statements are reasonable based on information available to us on the date such forward-looking statements are made, no assurances can be given as to future results, levels of activity and achievements. All subsequent forward-looking statements, whether written or oral, attributable to us or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements.

        Additional factors are described in our AIF (as defined herein) dated March 23, 2017 which is filed with the securities commissions or similar authorities in Canada and incorporated by reference in this prospectus and any applicable prospectus supplement. You should also carefully consider the matters discussed under "Risk Factors" in this prospectus and any applicable prospectus supplement.

        Except as required under applicable securities laws, we assume no obligation to update publicly or otherwise revise any forward-looking statements, whether as a result of new information, future events or otherwise, or the foregoing factors affecting this information, should circumstances or management estimates or opinions change.

NOTE REGARDING RESERVES DISCLOSURE

        The securities regulatory authorities in Canada have adopted National Instrument 51-101—Standards of Disclosure for Oil and Gas Activities ("NI 51-101"), which imposes oil and gas disclosure standards for Canadian public issuers engaged in oil and gas activities. NI 51-101 permits oil and gas issuers, in their filings with Canadian securities regulatory authorities, to disclose proved and proved plus probable reserves, to disclose resources, and to disclose reserves and production before deducting royalties. Probable reserves are of a higher uncertainty and are less likely to be accurately estimated or recovered than proved reserves.

        We are required to disclose reserves in accordance with Canadian securities law requirements and the disclosure of proved and probable reserves in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein and therein is in accordance with NI 51-101. The SEC definitions of proved and probable reserves are different from the definitions contained in NI 51-101; therefore, proved and probable reserves disclosed in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein and therein in compliance with NI 51-101 may not be comparable to United States standards. The SEC requires United States oil and gas reporting companies, in their filings with the SEC, to disclose only proved reserves after the deduction of royalties and production due to others but permits the optional disclosure of probable and possible reserves.

        In addition, as permitted by NI 51-101, we have determined and disclosed the net present value of future net revenue from our reserves in our NI 51-101 compliant reserves disclosure using forecast prices and costs. The SEC requires that reserves and related future net revenue be estimated based on historical 12-month average prices and current costs, but permits the optional disclosure of revenue estimates based on different price and cost criteria.

Table of Contents

        This prospectus, any applicable prospectus supplement and the documents incorporated by reference herein and therein contain disclosure respecting oil and gas production expressed as "cubic feet of natural gas equivalent" and "barrels of oil equivalent" or "BOE". All equivalency volumes have been derived using the ratio of six thousand cubic feet of natural gas to one barrel of oil. Equivalency measures may be misleading, particularly if used in isolation. A conversion ratio of six thousand cubic feet of natural gas to one barrel of oil is based on an energy equivalence conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. In comparing the value ratio using current crude oil prices relative to natural gas prices, the six thousand cubic feet of natural gas to one barrel of oil conversion ratio may be misleading as an indication of value.

        For additional information regarding the presentation of our reserves and other oil and gas information, see the section entitled "Form 51-101F1 Statement of Reserves Data and Other Information" in our AIF, which is incorporated by reference in this prospectus.

Under the multijurisdictional disclosure system adopted by the United States and the provinces of Canada, these reports and other information (including financial information) may be prepared, in part, in accordance with the disclosure requirements of Canada, which differ from those in the United States.

        In connection with the Acquisitions and as further described in the Business Acquisition Report, we issued: (i) on May 31, 2017, 97,560,975 Common Shares; (ii) on May 30, 2017, 2.95% notes due January 15, 2023 with an aggregate principal amount of US$1 billion, 3.85% notes due June 1, 2027 with an aggregate principal amount of US$1.25 billion and 4.95% notes due June 1, 2047 with an aggregate principal amount of US$750 million; and (iii) on May 30, 2017, 2.05% medium term notes due June 1, 2020 with an aggregate principal amount of $900 million, 3.42% medium term notes due December 1, 2026 with an aggregate principal amount of $600 million and 4.85% medium term notes due May 30, 2047 with an aggregate principal amount of $300 million.

        For the purposes of financing a portion of the cash purchase price and expenses relating to the Acquisitions, on May 4, 2017, a syndicate of lenders committed to provide to the Company: (i) a senior unsecured 364-day term credit facility in an aggregate principal amount of up to $6 billion on a fully underwritten basis (the "Bridge Facility"); and (ii) a senior unsecured three year term loan facility in an aggregate principal amount of up to $3 billion (the "Term Loan Facility"). The Bridge Facility was cancelled on May 30, 2017 following the note issuances described above. The Term Loan Facility will mature on May 31, 2020 and is subject to annual amortization of 5% of the original balance. As at May 31, 2017, being the closing date of the Acquisitions, $3 billion was drawn on the Term Loan Facility, including a US$375 million letter of credit regarding a deferred payment due to Marathon Oil Dutch Holdings B.V. in the first quarter of 2018.

        On June 29, 2017, we entered into an amending agreement to our $1,500 million non-revolving term credit facility maturing April 4, 2018 to extend the maturity date of the facility to October 15, 2019 and to increase the principal amount authorized under the facility to $2,200 million. The

Registration Rights Agreement

        On May 31, 2017, as part of the Acquisitions, the Company acquired a direct 60% working interest in the Athabasca Oil Sands Project along with working interests in other ancillary non-producing oil sands leases from Shell Canada Limited ("Shell") and its affiliates (the "Shell Acquisition").

        In connection with the Shell Acquisition, Canadian Natural, SCE, SCR and SG entered into a registration rights agreement (the "Registration Rights Agreement"), which provides SCE, SCR, SG and any transferees to whom their rights have been transferred in accordance with the Registration Rights Agreement (the "Holders") with certain rights in respect of the 97,560,975 Common Shares issued to SCE and SCR as at the closing date of the Shell Acquisition and any Common Shares or other securities of Canadian Natural received by the Holders as a result of a dividend, distribution, exchange, share split, recapitalization or other corporate event in respect of the Common Shares (collectively, the "Registrable Securities").

        The Registration Rights Agreement provides that Canadian Natural shall, within 100 days of the closing of the Shell Acquisition, prepare and file a preliminary and final short form base shelf prospectus covering the distribution of the Registrable Securities in certain provinces of Canada, as well as a registration statement with the SEC to effect a registration of the Registrable Securities in the U.S. (the "Shelf Qualification Right"). Canadian Natural is also required to use reasonable efforts to obtain a receipt for such final short form base shelf prospectus in respect thereof and to cause the applicable registration statement in the U.S. to be declared effective as promptly as practicable.

        Subject to certain limits, qualifications and applicable blackout periods, the Registration Rights Agreement provides the Holders with the right at any time during the period commencing, with respect to the distribution of Registrable Securities in Canada, on the date of the issuance of the receipt in respect of the final base shelf prospectus filed in Canada pursuant to the Shelf Qualification Right, and with respect to the registration of Registrable Securities in the U.S., on the date the applicable registration statement becomes effective, and in each case terminating on the date on which the Holders hold in aggregate less than 0.75% of the Common Shares issued and outstanding (the "Qualification Period"), to effect an offering by the Holders of all or part of their Registrable Securities included in the applicable base shelf prospectus or registration statement.

        In addition, if during the Qualification Period Canadian Natural proposes to file a prospectus, prospectus supplement or registration statement in Canada and/or the U.S. with respect to Common Shares or any securities convertible into, or exchangeable or exercisable for, Common Shares, then subject to certain limits and qualifications, Canadian Natural will be required to provide written notice to the Holders of its intention to do so. Subject to certain limits and qualifications, Canadian Natural is required to use reasonable efforts to include in the proposed distribution such number of Registrable Securities as the Holders shall request on the same terms and conditions as Canadian Natural's proposed distribution.

        The Holders may transfer the registration rights provided for under the Registration Rights Agreement to their affiliates and, in connection with transfers of at least 32,195,121 Common Shares,

PLAN OF DISTRIBUTION

        The Selling Shareholders may distribute Common Shares from time to time: (i) through underwriters purchasing as principal; (ii) directly pursuant to applicable statutory exemption or discretionary exemptions from registration; or (iii) through agents in Canada and elsewhere where permitted by law.

        The Common Shares may be distributed: (i) at fixed prices or non-fixed prices, such as prices determined by reference to the prevailing price of the Common Shares in a specified market; (ii) at market prices prevailing at the time of distribution; or (iii) at prices to the negotiated with purchasers, and as set forth in an accompanying prospectus supplement. Each prospectus supplement will identify the underwriter or agent, if any, engaged in connection with the distribution of the Common Shares and will set forth the terms of the distribution of the Common Shares, including the net proceeds to the Selling Shareholder(s) and the portion of expenses borne by, the Selling Shareholder(s) and/or the Corporation, and, to the extent applicable, any fees, discounts or any other compensation payable to underwriters or agents, if applicable, and any other material terms. If offered on a non-fixed price basis, Common Shares may be offered at market prices prevailing at the time of sale or at prices to be negotiated with purchasers at the time of sale, which prices may vary as between purchasers and during the period of distribution. If Common Shares are offered on a non-fixed price basis, the underwriters' or agents' compensation will be increased or decreased by the amount by which the aggregate price paid for Common Shares by the purchasers exceeds or is less than the gross proceeds paid by the underwriters or agents to us. Only underwriters or agents so named in the prospectus supplement are deemed to be underwriters or agents in connection with the Common Shares offered thereby.

        If underwriters purchase Common Shares from any Selling Shareholders as principal, the Common Shares will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale, at market prices prevailing at the time of sale or at prices related to such prevailing market prices. The obligations of the underwriters to purchase such Common Shares as principal are expected to be subject to certain conditions precedent, and the underwriters will be obligated to purchase all the Common Shares offered by the prospectus supplement if any of such Common Shares are purchased. Any public offering price and any discounts or concessions allowed or re-allowed or paid to underwriters or agents may be changed from time to time.

        The Common Shares may also be distributed directly by any Selling Shareholder, provided registration is not required or pursuant to applicable statutory or discretionary exemptions from registration, at such prices and upon such terms as agreed to by the Selling Shareholder(s) and the purchaser or through agents designated by the Selling Shareholder(s) from time to time. Any agent involved in the distribution of the Common Shares in respect of which this Prospectus is delivered will be named, and any commission payable by the Selling Shareholder(s) and/or the Company to such

agent will be set forth, in the applicable prospectus supplement. Unless otherwise indicated in the prospectus supplement, any agent could be acting on a best efforts basis for the period of its appointment.

        The Selling Shareholder(s) may agree to pay any underwriters a commission for various services relating to the distribution of any Common Shares. Any underwriters and agents who participate in a distribution of the Common Shares may be entitled under agreements to be entered into with the Selling Shareholder(s) and/or the Company to indemnification by the Selling Shareholder(s) and the Company, as applicable, against certain liabilities, including liabilities under securities legislation, or to contribution with respect to payments which such underwriters and agents may be required to make in respect thereof.

        To the extent permitted by applicable law, in connection with any distribution of Common Shares (unless otherwise specified in a prospectus supplement), any underwriters or agents, when purchasing as principal, may over-allot or effect transactions intended to fix or stabilize or maintain the market price of the Common Shares at a level above that which might otherwise prevail in the open market.

PART II

INFORMATION NOT REQUIRED TO BE DELIVERED
TO OFFEREES OR PURCHASERS

Indemnification

        Under the Business Corporations Act (Alberta) (the "ABCA"), the Registrant may indemnify a present or former director or officer or a person who acts or acted at the Registrant's request as a director or officer of a body corporate of which the Registrant is or was a shareholder or creditor, and his heirs and legal representatives, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which he is made a party by reason of being or having been a director or officer of the Registrant or that body corporate, if the director or officer acted honestly and in good faith with a view to the best interests of the Registrant, and, in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, had reasonable grounds for believing that his conduct was lawful. Such indemnification may be in connection with a derivative action only with court approval. A director or officer is entitled to indemnification from the Registrant as a matter of right if he or she was substantially successful on the merits in his defence of the action or proceedings, fulfilled the conditions set forth above, and is fairly and reasonably entitled to indemnity.

        The by-laws of the Registrant provide that, subject to the limitations contained in the ABCA, the Registrant shall indemnify a director or officer, a former director or officer, or a person who acts or acted at the Registrant's request as a director or officer of a body corporate of which the Registrant is or was a shareholder or creditor, and his heirs, executors, administrators and other legal representatives, to the fullest extent which may from time to time be permitted by the ABCA, from and against, (a) all costs, charges and expenses that he incurs in respect of any civil, criminal or administrative action or proceeding that is proposed or commenced against him by reason of being or having been a director or officer of the Registrant, and (b) all other costs, charges and expenses that he sustains or incurs in respect of the affairs of the Registrant, except in respect of an action by or on behalf of the Registrant, or such body corporate, to procure a judgment in its favor.

        The by-laws of the Registrant provide that the Registrant may, subject to the limitations contained in the ABCA, purchase and maintain insurance for the benefit of any director or officer as such against any liability incurred by him in his capacity as a director or officer of the Registrant or as a director or officer of any body corporate where he acts or acted in that capacity at the Registrant's request. The Registrant has purchased third party director and officer liability insurance.

        Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended (the "Act") may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable.
