PART I
INFORMATION REQUIRED TO BE DELIVERED TO OFFEREES OR PURCHASERS

No securities regulatory authority has expressed an opinion about these securities and it is an offence to claim otherwise.

This short form base shelf prospectus has been filed under legislation in each of the provinces of Canada that permits certain information about these securities to be determined after this short form base shelf prospectus has become final and that permits the omission from this short form base shelf prospectus of that information. The legislation requires the delivery to purchasers of a prospectus supplement containing the omitted information within a specified period of time after agreeing to purchase any of these securities, except in cases where an exemption from such delivery requirements has been obtained.

This short form base shelf prospectus constitutes a public offering of these securities only in those jurisdictions where they may be lawfully offered for sale and therein only by persons permitted to sell such securities.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC NOR HAS THE SEC PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Information has been incorporated by reference in this short form base shelf prospectus from documents filed with securities commissions or similar authorities in Canada. Copies of the documents incorporated herein by reference may be obtained on request without charge from the Investor Relations Department of Westport Fuel Systems Inc. ("Westport Fuel Systems" the "Corporation", "we", "us" or "our") at 101 – 1750 West 75th Avenue, Vancouver, British Columbia V6P 6G2, telephone (604) 718-2046 and are also available electronically at www.sedar.com.

This short form base shelf prospectus (the "Prospectus") relates to the offering for sale from time to time, during the 25-month period that this Prospectus, including any amendments, remains valid, of up to U.S.$400,000,000 (or the equivalent in other currencies or currency units based on the applicable exchange rate at the time of the offering) aggregate initial offering price of our common shares ("Common Shares"), preferred shares ("Preferred Shares"), subscription receipts ("Subscription Receipts"), warrants to purchase Common Shares ("Warrants"), senior or subordinated debt securities ("Debt Securities"), and/or units comprised of one or more of the other securities described in this Prospectus in any combination, ("Units" and, together with the Common Shares, Preferred Shares, Subscription Receipts, Debt Securities and Warrants, the "Securities"). The Securities may be offered by us or by our securityholders. We, or our securityholders, may offer Securities in such amount and, in the case of the Preferred Shares, Subscription Receipts, Warrants, Debt Securities, and Units, with such terms as we, or our securityholders, may determine in light of market conditions. We, or our securityholders, may sell the Preferred Shares, Subscription Receipts, Warrants, and Debt Securities in one or more series.

The distribution of Securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at non-fixed prices, such as market prices prevailing at the time of sale or prices related to such prevailing market prices to be negotiated with purchasers, including sales in transactions that are deemed to be "at-the-market distributions" as defined in National Instrument 44-102 Shelf Distributions ("NI 44-102") including sales made directly on the TSX, the Nasdaq or other existing trading markets for the Securities, and as set forth in one or more supplements to this Prospectus (each, a "Prospectus Supplement"). This Prospectus may qualify an "at-the-market distribution", as defined under NI 44-102 (an "ATM Distribution").

There are certain risk factors that should be carefully reviewed by prospective purchasers. See "Risk Factors".

All shelf information permitted under applicable laws to be omitted from this Prospectus will be contained in one or more Prospectus Supplements that will be delivered to prospective purchasers together with this Prospectus, except in cases where an exemption from such delivery requirements is available or has been obtained. 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 Securities to which the Prospectus Supplement pertains.

The specific variable terms of any offering of Securities will be set forth in a Prospectus Supplement, including where applicable: (i) in the case of the Common Shares, the number of Common Shares offered, the currency (which may be Canadian dollars or any other currency), the issue price and any other specific terms; (ii) in the case of Preferred Shares, the number of Preferred Shares being offered, the designation of the series, the offering price, dividend rate, if any, and any other specific terms; (iii) in the case of Subscription Receipts, the number of Subscription Receipts offered, the currency (which may be Canadian dollars or any other currency), the issue price, the terms and procedures for the exchange of the Subscription Receipts and any other specific terms; (iv) in the case of Warrants, the designation, the number of Warrants offered, the currency (which may be Canadian dollars or any other currency), number of the Common Shares that may be acquired upon exercise of the Warrants, the exercise price, dates and periods of exercise, adjustment procedures and any other specific terms; (v) in the case of Debt Securities, the designation, aggregate principal amount and authorized denominations of the Debt Securities, any limit on the aggregate principal amount of the Debt Securities, the currency (which may be Canadian dollars or any other currency), the issue price (at par, at a discount or at a premium), the issue and delivery date, the maturity date (including any provisions for the extension of a maturity date), the interest rate (either fixed or floating and, if floating, the method of determination thereof), the interest payment date(s), the provisions (if any) for subordination of the Debt Securities to other indebtedness, any redemption or purchase provisions, any repayment provisions, any terms entitling the holder to exchange or convert the Debt Securities into other securities, any defeasance provisions, security (if any) applicable to such Debt Securities and any other specific terms; and (vi) in the case of Units, the designation, the number of Units offered, the offering price, the currency (which may be Canadian dollars or any other currency), terms of the Units and of the securities comprising the Units and any other specific terms. Where required by statute, regulation or policy, and where Securities are offered in currencies other than Canadian dollars, appropriate disclosure of foreign exchange rates applicable to such Securities will be included in the Prospectus Supplement describing such Securities.

You should read this Prospectus and any Prospectus Supplement before you invest in any Securities.

We have filed with the U.S. Securities and Exchange Commission (the "SEC") a registration statement on Form F-10 relating to the Securities. This Prospectus, which constitutes a part of the registration statement, does not contain all of the information contained in the registration statement, certain items of which are contained in the exhibits to the registration statement as permitted by the rules and regulations of the SEC. Statements included or incorporated by reference into this Prospectus about the contents of any contract, agreement or other documents referred to are not necessarily complete, and in each instance, you should refer to any applicable full version or more detailed description of the contract, agreement or other document, as may be available electronically on SEDAR at www.sedar.com or on Westport Fuel Systems' website at www.wfsinc.com, for a more complete description of the matter involved. Each such statement is qualified in its entirety by such reference. See "Where You Can Find Additional Information".

This offering is made by a Canadian issuer that is permitted, under a multijurisdictional disclosure system adopted by the United States and Canada (the "MJDS"), to prepare this Prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are different from those of the United States. The financial statements incorporated by reference into this Prospectus have been prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") and are subject to Canadian and U.S. auditing and auditor independence standards.

Prospective investors should be aware that the acquisition of the Securities may have tax consequences both in the United States and in Canada. Such consequences for investors who are resident in, or citizens of, the United States may not be described fully herein or in any applicable Prospectus Supplement with respect to a particular offering of Securities. Prospective investors should consult their own tax advisors prior to deciding to purchase any of the Securities. See "Certain Income Tax Considerations".

The enforcement by investors of civil liabilities under United States federal securities laws may be affected adversely by the fact that we are incorporated or organized under the laws of Alberta, Canada, that some or all of our officers and directors are residents of Canada, that some or all of the underwriters or experts named in this Prospectus are residents of Canada, and that all or a substantial portion of our assets and the assets of such persons are located outside the United States. See "Enforcement of Civil Liabilities".

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC NOR HAS THE SEC PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Our issued and outstanding Common Shares are listed for trading on the Toronto Stock Exchange ("TSX") under the trading symbol "WPRT" and on the Nasdaq Global Select Market ("Nasdaq") under the trading symbol "WPRT". On March 15, 2021, the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the TSX was Cdn.$12.79 per Common Share and the closing price of the Common Shares on Nasdaq was U.S.$10.25 per Common Share. Any offering of Securities other than Common Shares will be a new issue of securities with no established trading market. Unless otherwise specified in the applicable Prospectus Supplement, the Securities to be offered thereunder will not be listed on any securities exchange. Unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Securities other than Common Shares may be sold and purchasers may not be able to resell such Securities purchased under this Prospectus or any applicable Prospectus Supplement. This may affect the pricing of these Securities in the secondary market (if any), the transparency and availability of trading prices, the liquidity of the Securities, and the extent of issuer regulation. See "Risk Factors".

No underwriter has been involved in the preparation of, or has performed a review of, the contents of this Prospectus.

Subject to applicable laws, and other than in relation to an ATM Distribution, in connection with any offering of Securities, the underwriters, dealers or agents, as the case may be, may over-allot or conduct transactions intended to stabilize, maintain or otherwise affect the market price for the Securities at levels other than those which otherwise might prevail in the open market. Such transactions may be commenced, interrupted or discontinued at any time. See "Plan of Distribution".

No underwriter or dealer of an ATM Distribution, and no person or company acting jointly or in concert with such underwriter or dealer, may, in connection with the distribution, enter into any transaction that is intended to stabilize or maintain the market price of the securities or securities of the same class as the securities distributed under this Prospectus, including selling an aggregate number or principal amount of securities that would result in the underwriter creating an over-allocation position in the securities. The Prospectus Supplement relating to a particular offering of Securities will identify each person who may be deemed to be an underwriter, dealer or agent, as the case may be, with respect to such offering and will set forth the terms of the offering of such Securities, including, to the extent applicable, the amounts, if any, to be purchased by underwriters, the plan of distribution for such securities, the public offering price, the proceeds expected to be received by us or any selling security holder, any fees, discounts or other compensation payable to underwriters, dealers or agents, and any other material terms of the plan of distribution will be named in the related Prospectus Supplement.

Prospective investors are advised that it may not be possible for investors to enforce judgements obtained in Canada against any person that resides outside of Canada, even if the party has appointed an agent for service of process.

Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute part of this Prospectus.

Upon a new information circular relating to an annual meeting of holders of Common Shares being filed by us with the securities commission or similar regulatory authority in each of the provinces of Canada during the term of this Prospectus, the information circular for the preceding annual meeting of holders of Common Shares shall be deemed no longer to be incorporated into this Prospectus for purposes of future offers and sales of Securities under this Prospectus.

WHERE YOU CAN FIND ADDITIONAL INFORMATION

We have filed with the SEC a registration statement on Form F-10 relating to the Securities. This Prospectus, which constitutes a part of the registration statement, does not contain all of the information contained in the registration statement, certain items of which are contained in the exhibits to the registration statement as permitted by the rules and regulations of the SEC. Statements included or incorporated by reference into this Prospectus about the contents of any contract, agreement or other documents referred to are not necessarily complete, and in each instance, you should refer to the exhibits for a more complete description of the matter involved. Each such statement is qualified in its entirety by such reference.

We are subject to the information requirements of the U.S. Exchange Act and applicable Canadian securities legislation, and in accordance therewith we file reports and other information with the SEC and with the securities regulatory authorities in Canada. Under the MJDS adopted by Canada and the United States, documents and other information that we file with the SEC may be prepared in accordance with the disclosure requirements of Canada, which are different from those of the United States. As a foreign private issuer, we are exempt from the rules under the U.S. Exchange Act prescribing the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the U.S. Exchange Act. In addition, we are not required to publish financial statements as promptly as United States companies.

Investors may read any document that we have filed with the SEC and may also obtain copies of those documents by paying a fee at the public reference room of the SEC at 100 F Street, N.E., Washington, D.C. 20549. Investors should call the SEC at 1-800-SEC-0330 or access its website at www.sec.gov for further information about the public reference rooms. Investors may read and download some of the documents we have filed with the SEC at the SEC's Electronic Data Gathering, Analysis and Retrieval system at www.sec.gov. We are also subject to filing requirements prescribed by the securities legislation of all Canadian provinces. These filings are available electronically from SEDAR at www.sedar.com.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a corporation existing under the Business Corporations Act (Alberta). A number of our officers and directors and some of the experts named in this Prospectus, are residents of Canada or otherwise reside outside the United States, and all, or a substantial portion of their assets and a substantial portion of our assets, 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 Securities 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 Securities 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, officers and experts under the United States federal securities laws or the securities laws of any state of the United States.

We have been advised by our Canadian counsel that a judgment of a United States court predicated solely upon civil liability under United States federal securities laws would likely 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 such counsel, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon United States federal securities laws.

We filed with the SEC, concurrently with our registration statement on Form F-10 of which this Prospectus is a part, an appointment of agent for service of process 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 the Securities under this Prospectus.

USE OF PROCEEDS

Unless otherwise indicated in an applicable Prospectus Supplement relating to an offering of Securities, we expect to use the net proceeds we receive from the sale of Securities to finance future growth opportunities including acquisitions and investments, to finance our capital expenditures, to reduce our outstanding indebtedness, for working capital purposes or for general corporate purposes, as will be further described in one or more Prospectus Supplements. All Prospectus Supplements under the Prospectus will include reasonable detail of the use of proceeds. The amount of net proceeds to be used for each of the principal purposes will be described in the applicable Prospectus Supplement. All expenses relating to an offering of Securities and any compensation paid to underwriters, dealers or agents will be paid out of our general funds. From time to time, we may issue debt securities or incur additional indebtedness other than through the issue of Securities pursuant to this Prospectus. We will not receive any proceeds from any sales of Securities by any selling securityholders pursuant to a secondary offering. More detailed information regarding anticipated expenses associated with any underwriter, broker, dealer manager or similar securities industry professionals in respect of any sales by us or a selling securityholder will be described in any applicable Prospectus Supplement.

PLAN OF DISTRIBUTION

New Issue

We may sell Securities to or through underwriters, dealers, placement agents or other intermediaries and also may sell Securities directly to purchasers or through agents, subject to obtaining any applicable exemption from registration requirements.

In connection with the sale of Securities, underwriters may receive compensation from us or from purchasers of Securities for whom they may act as agents in the form of discounts, concessions or commissions. Underwriters, dealers, placement agents or other intermediaries that participate in the distribution of Securities may be deemed to be underwriters and any discounts or commissions received by them from us and any profit on the resale of Securities by them may be deemed to be underwriting discounts and commissions under applicable securities legislation.

If so indicated in the applicable Prospectus Supplement, we may authorize dealers or other persons acting as our agents to solicit offers by certain institutions to purchase the Securities directly from us pursuant to contracts providing for payment and delivery on a future date. These contracts will be subject only to the conditions set forth in the applicable Prospectus Supplement or supplements, which will also set forth the commission payable for solicitation of these contracts.

The Prospectus Supplement relating to any offering of Securities will also set forth the terms of the offering of the Securities, including, to the extent applicable, the initial offering price, the proceeds to us, the underwriting discounts or commissions, and any other discounts or concessions to be allowed or reallowed to dealers. Underwriters with respect to any offering of Securities sold to or through underwriters will be named in the Prospectus Supplement relating to such offering.

Under agreements which may be entered into by us, underwriters, dealers, placement agents and other intermediaries who participate in the distribution of Securities may be entitled to indemnification by us against certain liabilities, including liabilities under applicable securities legislation. The underwriters, dealers, placement agents and other intermediaries with whom we enter into agreements may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

Any offering of Preferred Shares, Subscription Receipts, Warrants, Debt Securities, or Units that is not a secondary offering will be a new issue of securities with no established trading market. Unless otherwise specified in the applicable Prospectus Supplement, the Preferred Shares, Subscription Receipts, Warrants, Debt Securities or Units will not be listed on any securities exchange. Unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Preferred Shares, Subscription Receipts, Warrants, Debt Securities or Units may be sold and purchasers may not be able to resell Preferred Shares, Subscription Receipts, Warrants, Debt Securities or Units purchased under this Prospectus or any Prospectus Supplement. This may affect the pricing of the Preferred Shares, Subscription Receipts, Warrants, Debt Securities or Units in the secondary market, the transparency and availability of trading prices, the liquidity of the securities, and the extent of issuer regulation. Certain dealers may make a market in the Preferred Shares, Subscription Receipts, Warrants, Debt Securities or Units, as applicable, but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that any dealer will make a market in the Preferred Shares, Subscription Receipts, Warrants, Debt Securities or Units or as to the liquidity of the trading market, if any, for the Preferred Shares, Subscription Receipts, Warrants, Debt Securities or Units.

Secondary Offering

This Prospectus may also, from time to time, relate to the offering of our Securities by certain selling securityholders. The selling securityholders may sell all or a portion of our Securities beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If our Securities are sold through underwriters or broker-dealers, the selling securityholders will be responsible for underwriting discounts or commissions or agent's commissions. Our Securities may be sold by the selling securityholders in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, as follows:

on any national securities exchange or quotation service on which the Securities may be listed or quoted at the time of sale;
in the over-the-counter market;
in transactions otherwise than on these exchanges or systems or in the over-the-counter market;
through the writing of options, whether such options are listed on an options exchange or otherwise;
ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
block trades in which the broker-dealer will attempt to sell the Securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;
purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
an exchange distribution in accordance with the rules of the applicable exchange;
privately negotiated transactions;
short sales;
sales pursuant to Rule 144 under United States Securities Act of 1933, as amended (the "U.S. Securities Act");
broker-dealers may agree with the selling securityholders to sell a specified number of such Securities at a stipulated price per Security;
a combination of any such methods of sale; and
any other method permitted pursuant to applicable law.

If the selling securityholders effect such transactions by selling our Securities to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling securityholders or commissions from purchasers of our Securities for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of our Securities or otherwise, the selling securityholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of our Securities in the course of hedging in positions they assume. The selling securityholders may also sell our Securities short and deliver our Securities covered by this Prospectus to close out short positions and to return borrowed Securities in connection with such short sales.

The selling securityholders may also loan or pledge our Securities to broker-dealers that in turn may sell such Securities. The selling securityholders may pledge or grant a security interest in some or all of the Securities owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell our Securities from time to time pursuant to this Prospectus or any supplement to this Prospectus filed under General Instruction II.L. of Form F-10 under the U.S. Securities Act, amending, if necessary, the list of selling securityholders to include, pursuant to a prospectus amendment or Prospectus Supplement, the pledgee, transferee or other successors in interest as selling securityholders under this Prospectus. The selling securityholders also may transfer and donate our Securities in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this Prospectus.

The selling securityholders and any broker-dealer participating in the distribution of our Securities may be deemed to be "underwriters" within the meaning of the U.S. Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the U.S. Securities Act. At the time a particular offering of our Securities is made, a Prospectus Supplement, if required, will be distributed which will identify the selling securityholders and provide the other information set forth under "Selling Securityholders", set forth the aggregate amount of our Securities being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling securityholders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers.

Under the securities laws of some states, our Securities may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states our Securities may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

There can be no assurance that any securityholder will sell any or all of our Securities registered pursuant to the registration statement, of which this Prospectus forms a part.

The selling securityholders and any other person participating in such distribution will be subject to applicable provisions of Canadian and United States securities legislation and the rules and regulations thereunder, including, without limitation, Regulation M under the U.S. Exchange Act, which may limit the timing of purchases and sales of any of our Securities by the selling securityholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of our Securities to engage in market-making activities with respect to our Securities. All of the foregoing may affect the marketability of our Securities and the ability of any person or entity to engage in market-making activities with respect to our Securities.

Once sold under the shelf registration statement, of which this Prospectus forms a part, our Securities will be freely tradable in the hands of persons other than our affiliates.

EARNINGS COVERAGE

If we offer Debt Securities or Preferred Shares having a term to maturity in excess of one year, under this Prospectus and any applicable Prospectus Supplement, the applicable Prospectus Supplement will include earnings coverage ratios giving effect to the issuance of such securities.

PURCHASERS' STATUTORY AND CONTRACTUAL RIGHTS

Securities legislation in certain of the provinces of Canada provides purchasers with the right to withdraw from an agreement to purchase securities. This right may be exercised within two business days after receipt or deemed receipt of a prospectus, the accompanying Prospectus Supplement relating to securities purchased by a purchaser and any amendment thereto, irrespective of the determination at a later date of the purchase price of the securities distributed. The legislation further provides a purchaser with remedies for rescission or damages if the prospectus, an accompanying Prospectus Supplement relating to securities purchased by a purchaser or any amendment contains a misrepresentation or are not delivered to the purchaser, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation in the purchaser's province. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province for the particulars of these rights or consult with a legal advisor.

Original purchasers of Debt Securities, Subscription Receipts and Warrants (including any of the foregoing contained in any Units), which are convertible into other securities of the Corporation will have a contractual right of rescission against us in respect of the conversion, exchange or exercise of such Debt Securities, Subscription Receipts and Warrants.

The contractual right of rescission will entitle such original purchasers to receive, in addition to the amount paid on original purchase of the Warrant or Subscription Receipt, as the case may be, the amount paid upon conversion, exchange or exercise upon surrender of the underlying securities gained thereby, in the event that this Prospectus (as supplemented or amended) contains a misrepresentation, provided that: (i) the conversion, exchange or exercise takes place within 180 days of the date of the purchase of the convertible, exchangeable or exercisable security under this Prospectus; and (ii) the right of rescission is exercised within 180 days of the date of purchase of the convertible, exchangeable or exercisable security under this Prospectus. This contractual right of rescission will be consistent with the statutory right of rescission described under section 131 of the Securities Act (British Columbia), and is in addition to any other right or remedy available to original purchasers under section 131 of the Securities Act (British Columbia) or otherwise at law.

Original purchasers are further advised that in certain provinces the statutory right of action for damages in connection with a prospectus misrepresentation is limited to the amount paid for the convertible, exchangeable or exercisable security that was purchased under a prospectus, and therefore a further payment at the time of conversion, exchange or exercise may not be recoverable in a statutory action for damages. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province for the particulars of these rights, or consult with a legal advisor.

(3) Notwithstanding anything in this section, a person referred to in subsection (1) is entitled to indemnity from the corporation in respect of all costs, charges and expenses reasonably incurred by the person in connection with the defence of any civil, criminal or administrative action or proceeding to which the person is made a party by reason of being or having been a director or officer of the corporation or body corporate, if the person seeking indemnity

(a)

was substantially successful on the merits in the person's defence of the action or proceeding,

(b)

fulfils the conditions set out in subsection (1)(a) and (b), and

(c)

is fairly and reasonably entitled to indemnity.

(3.1) A corporation may advance funds to a person in order to defray the costs, charges and expenses of a proceeding referred to in subsection (1) or (2), but if the person does not meet the conditions of subsection (3) he or she shall repay the funds advanced.

(4) A corporation may purchase and maintain insurance for the benefit of any person referred to in subsection (1) against any liability incurred by the person

(a)

in the person's capacity as a director or officer of the corporation, except when the liability relates to the person's failure to act honestly and in good faith with a view to the best interests of the corporation, or

(b)

in the person's capacity as a director or officer of another body corporate if the person acts or acted in that capacity at the corporation's request, except when the liability relates to the person's failure to act honestly and in good faith with a view to the best interests of the body corporate.

II-1

(5) A corporation or a person referred to in subsection (1) may apply to the Court of Queen's Bench of Alberta for an order approving an indemnity under this section and the Court of Queen's Bench of Alberta may so order and make any further order it thinks fit.

(6) On an application under subsection (5), the Court of Queen's Bench of Alberta may order notice to be given to any interested person and that person is entitled to appear and be heard in person or by counsel.

Section 7 of the By-laws of the Registrant, contains the following provisions with respect to indemnification of the Registrant's directors and officers:

7.05 Limitation of Liability

Subject to the ABCA, no director or officer for the time being of the Registrant shall be liable for the acts, receipts, neglects or defaults if any other director or officer or employee, or for joining in any receipt or act for conformity, or for any loss, damage or expense happening to the Registrant through the insufficiency or deficiency of title to any property acquired by the Registrant or for or on behalf of the Registrant or for the insufficiency or deficiency of any security in or upon which any of the moneys of or belonging to the Registrant shall be placed or invested, or for any loss or damage arising from the bankruptcy, insolvency or tortious act of any person, firm or corporation including any person, firm or corporation with whom or with which moneys, securities or effects shall be lodged or deposited for any loss, conversation, misapplication or misappropriation of or any damage resulting from any dealings with moneys, securities or other assets of or belonging to the Registrant or for any other loss, damage or misfortune whatsoever which may happen in the execution of the duties of his respective office or trust or in relation thereto unless the same shall happen by or through his failure to exercise the powers and to discharge the duties of his office honestly and in good faith with a view to the best interests of the Registrant and through a failure to exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.

7.06 Indemnity

Subject to the ABCA, the Registrant shall indemnify a director or officer, a former director or officer, and 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 any amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect to any civil, criminal or administrative action or proceedings to which he is made a party by reason of being or having been a director of officer of the Registrant or such body corporate, if:

(a)

he acted honestly and in good faith with a view to the best interests of the Registrant; and

(b)

in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, he had reasonable grounds for believing that his conduct was lawful.

7.07 Insurance

The Registrant may, subject to and in accordance with the ABCA, purchase and maintain insurance for the benefit of any director or officer as such against liability incurred by him.

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, 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 SEC such indemnification is against public policy as expressed in the Act and is therefore unenforceable.
