Underwriters named in Schedule I hereto

c/o Oppenheimer & Co. Inc.

Ladies and Gentlemen:

Westport Fuel Systems Inc., an Alberta corporation (the “Company”), proposes, subject to the terms and conditions contained herein, to issue and sell to you and the other underwriters named on Schedule I to this Agreement (the “Underwriters”), for whom you are acting as Representative (the “Representative”), an aggregate of 16,700,000 shares (the “Firm Shares”) of the Company’s common shares (the “Common Shares”). The respective amounts of the Firm Shares to be purchased by each of the several Underwriters are set forth opposite their names on Schedule I hereto. In addition, the Company proposes to grant to the Underwriters an option to purchase up to an additional 2,505,000 Common Shares (the “Option Shares”) from the Company for the purpose of covering over-allotments in connection with the sale of the Firm Shares. The Firm Shares and the Option Shares are collectively called the “Shares.”

The Company has prepared and filed with the securities regulatory authorities (the “Canadian Commissions”) in each of the provinces of Canada other than Quebec (the “Qualifying Jurisdictions”), in accordance with Multilateral Instrument 11-102 Passport System (“MI 11-102”) and National Policy 11-202 Process for Prospectus Reviews in Multiple Jurisdictions, a preliminary short form base shelf prospectus dated July 24, 2015 (the “Canadian Preliminary Base Prospectus”) and a final short form base shelf prospectus dated August 6, 2015 (the “Canadian Final Base Prospectus”), in respect of up to Cdn.$750,000,000 aggregate principal amount of common shares, preferred shares, subscription receipts, warrants, debt

securities or units of the Company (collectively, the “Shelf Securities”). The British Columbia Securities Commission (the “Principal Regulator”) has issued a receipt for each of the Canadian Preliminary Base Prospectus and the Canadian Final Base Prospectus, which receipts evidence that receipts have been issued by the Ontario Securities Commission and that the Company has satisfied the conditions in MI 11-102 for the deemed issuance of a receipt by the Canadian Commissions for each of the Canadian Preliminary Base Prospectus and the Canadian Final Base Prospectus in each of the other Qualifying Jurisdictions. The term “Canadian Base Prospectus” means the Canadian Final Base Prospectus, including any documents incorporated therein by reference and the documents otherwise deemed to be a part thereof or included therein pursuant to Canadian Securities Laws (as hereinafter defined), at the time the Principal Regulator issued a receipt with respect thereto in accordance with Canadian Securities Laws, including National Instrument 44-101 Short Form Prospectus Distributions and National Instrument 44-102 Shelf Distributions (together, the “Canadian Shelf Procedures”). The Company has also prepared and filed with the Canadian Commissions in accordance with the Canadian Shelf Procedures, a preliminary prospectus supplement, dated July 13, 2017 (the “Canadian Preliminary Prospectus Supplement”), relating to the distribution of the Shares, which excluded certain pricing information and other information specific to the offering and sale of the Shares the Company is permitted to exclude from such Canadian Preliminary Prospectus Supplement under the Canadian Shelf Procedures (the “Shelf Information”) (the Canadian Preliminary Prospectus Supplement together with the Canadian Base Prospectus, and unless the context otherwise requires, including any documents incorporated therein by reference and the documents otherwise deemed to be a part thereof or included therein for the purposes of the distribution of the Shares pursuant to Canadian Securities Laws, the “Canadian Preliminary Prospectus”).

The Company has filed with the United States Securities and Exchange Commission (the “Commission”) a registration statement on Form F-10 (File No. 333-205869), including a base prospectus, relating to the Shelf Securities, including the Shares. The registration statement as amended at the time it becomes effective, including the information (if any) deemed to be part of the registration statement at the time of effectiveness under the Securities Act of 1933, as amended (the “Securities Act”), including the Canadian Base Prospectus with such deletions therefrom and additions thereto as are permitted or required by Form F-10 and the applicable rules and regulations of the Commission and including exhibits to such registration statement and all documents incorporated by reference in the prospectus contained therein, and including any amendments thereto filed prior to the date hereof, each in the form heretofore delivered or to be delivered to the Representative (hereinafter collectively referred to as the “Registration Statement”), has become effective in such form pursuant to Rule 467(a) under the Securities Act. The preliminary base prospectus filed as part of the Registration Statement, including all documents incorporated therein by reference, contained in the Registration Statement as initially filed with the Commission, is hereinafter called the “U.S. Preliminary Base Prospectus”; the base prospectus filed as part of the Registration Statement, including all documents incorporated therein by reference, contained in the Registration Statement on the date hereof, is hereinafter called the “U.S. Base Prospectus”; the preliminary prospectus supplement relating to the offering of the Shares, including all documents incorporated therein by reference, filed with the Commission pursuant to General Instruction II.L of Form F-10 under the Securities Act on July 14, 2017 together with the U.S. Base Prospectus, is hereinafter called the “U.S. Preliminary Prospectus”. If the Company has filed an abbreviated registration statement to register additional Common Shares pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. The term “Effective Date” shall mean each date that the Registration Statement and any post-effective amendment or amendments thereto became or become effective.

2

In addition, the Company will prepare and file, as soon as possible and in any event within two business days after the date of execution and delivery of this Agreement (i) with the Canadian Commissions a final prospectus supplement (the “Canadian Final Prospectus Supplement”) relating to the distribution of the Shares, which includes the Shelf Information omitted from the Canadian Preliminary Prospectus Supplement (the Canadian Final Prospectus Supplement together with the Canadian Base Prospectus, and including any documents incorporated therein by reference and the documents otherwise deemed to be a part thereof or included therein pursuant to Canadian Securities Laws (as defined herein), the “Canadian Final Prospectus”), and (ii) with the Commission, pursuant to General Instruction II.L of Form F-10, a final prospectus supplement relating to the distribution of the Shares (including all documents incorporated therein by reference, together with the U.S. Base Prospectus, the “U.S. Final Prospectus”).

The Company understands that the Underwriters propose to make a public offering of the Shares, as set forth in and pursuant to the Statutory Prospectus (as hereinafter defined) and the Final Prospectus, as soon after the Effective Date and the date of this Agreement as the Representative deems advisable. The Company hereby confirms that the Underwriters and dealers have been authorized to distribute or cause to be distributed each Preliminary Prospectus, and each Issuer Free Writing Prospectus (as hereinafter defined) and are authorized to distribute the Final Prospectus (as from time to time amended or supplemented if the Company furnishes amendments or supplements thereto to the Underwriters). The Offered Shares may not be offered or sold, directly or indirectly, in Canada or to any person resident in Canada.

1. Sale, Purchase, Delivery and Payment for the Shares. On the basis of the representations, warranties and agreements contained in, and subject to the terms and conditions of, this Agreement:

(a) The Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at a purchase price of $1.41 per share (the “Initial Price”), the number of Firm Shares set forth opposite the name of such Underwriter on Schedule I to this Agreement, subject to adjustment in accordance with Section 8 hereof. The Underwriters shall offer the Firm Shares to the public at the initial offering price of $1.50.

4

(b) The Company hereby grants to the several Underwriters an option to purchase, severally and not jointly, all or any part of the Option Shares at the Initial Price. The number of Option Shares to be purchased by each Underwriter shall be the same percentage (adjusted by the Representative to eliminate fractions) of the total number of Option Shares to be purchased by the Underwriters as such Underwriter is purchasing of the Firm Shares. Such option may be exercised only to cover over-allotments in the sales of the Firm Shares by the Underwriters and may be exercised at any time and from time to time, in whole or in part, commencing on the Firm Shares Closing Date (as defined below), and ending on the date that is 30 days after the Firm Shares Closing Date, in each case upon written, facsimile or telegraphic notice, or verbal or telephonic notice confirmed by written, facsimile or telegraphic notice, by the Representative to the Company, as the case may be, setting forth the number of Option Shares to be purchased and the time and date (if other than the Firm Shares Closing Date) of such purchase.

(c) Payment of the purchase price for, and delivery of the Firm Shares, in electronic or certificated form, shall be made at the offices of Oppenheimer & Co. Inc., 85 Broad Street, New York, New York 10004, at 10:00 a.m., New York City time, on the third business day following the date of this Agreement or at such time on such other date, not later than ten (10) business days after the date of this Agreement, as shall be agreed upon by the Company and the Representative (such time and date of delivery and payment are called the “Firm Shares Closing Date”). In addition, in the event that any or all of the Option Shares are purchased by the Underwriters, payment of the purchase price, and delivery of the Option Shares, in electronic or certificated form, shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company, on each date of delivery as specified in the notice from the Representative to the Company (such time and date of delivery and payment are called the “Option Shares Closing Date”). The Firm Shares Closing Date and any Option Shares Closing Date are called, individually, a “Closing Date” and, together, the “Closing Dates.”

(d) Payment shall be made to the Company by wire transfer of immediately available funds or by certified or official bank check or checks payable in New York Clearing House (same day) funds drawn to the order of the Company, against delivery of the certificates for the Shares to the Representative on behalf of the Underwriters.

(e) The Shares shall be registered in such names and shall be in such denominations as the Representative shall request at least two full business days before the Firm Shares Closing Date or, in the case of Option Shares, on the day of notice of exercise of the option as described in Section 1(b) and shall be delivered by or on behalf of the Company to the Representative for the account of such Underwriter. The Company will cause the certificates representing the Shares to be made available for checking and packaging, at such place as is designated by the Representative, on the full business day before the Firm Shares Closing Date (or the Option Shares Closing Date in the case of the Option Shares).

2. Representations and Warranties of the Company. The Company represents and warrants to each Underwriter as of the date hereof, as of the Firm Shares Closing Date and as of each Option Shares Closing Date (if any), as follows:

(a) The Company is a “foreign private issuer” (as defined in Rule 405 under the Securities Act) and is entitled to use Form F-10 under the Securities Act to register the offering of the Shares under the Securities Act. The Company has prepared and filed with the Commission an appointment of agent for service of process upon the Company on Form F-X (the “Form F-X”). The Registration Statement and the Form F-X conform, and any further amendments to the Registration Statement or the Form F-X will conform, in all material respects, to the requirements of the Securities Act.

(b) The Company is eligible to use the Canadian Shelf Procedures. No order preventing or suspending the use of the Canadian Base Prospectus or the Canadian Preliminary Prospectus or preventing the distribution of the Shares has been issued and no proceeding for that purpose has been initiated or, to the knowledge of the Company, threatened, by any of the Canadian Commissions; as of their respective dates, the Canadian Base Prospectus and the Canadian Preliminary Prospectus complied, and the Canadian Final Prospectus (and any further amendments or supplements thereto) will comply, in all material respects with all applicable securities laws in the Qualifying Jurisdictions and the respective rules, regulations, blanket rulings, orders and notices made thereunder and the local, uniform, national and multilateral instruments and policies adopted by the Canadian Commissions in the Qualifying Jurisdictions (collectively, “Canadian Securities Laws”); and each of the Canadian Commissions in the Qualifying Jurisdictions has issued or is deemed to have issued receipts for the Canadian Preliminary Base Prospectus and the Canadian Base Prospectus.

The Company has made at least one version of the Road Show available without restriction by means of graphic communication to any person, including any potential investor in the Shares (and if there is more than one version of a Road Show used in connection with the offering of the Shares that is a written communication, the version available without restriction was made available no later than the other versions).

As used in this Section and elsewhere in this Agreement:

Any material required to be filed by the Company pursuant to Rule 433(d) of the Rules has been or will be made in the manner and within the time period required by such Rule 433(d).

(i) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Shares or until any earlier date that the Company notified or notifies the Representative as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, including any document incorporated by reference therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified, the Statutory Prospectus or the Final Prospectus.

8

If at any time following issuance of an Issuer Free Writing Prospectus and prior to the expiration of the Underwriters’ option to purchase the Option Shares or the Option Shares Closing Date, whichever is earlier, there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, the Statutory Prospectus or the Final Prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances prevailing at the subsequent time, not misleading, the Company has promptly notified or will promptly notify the Representative and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(j) The Company is not an “ineligible issuer” in connection with the offering of the Shares pursuant to Rules 164, 405 and 433 under the Securities Act. Any free writing prospectus that the Company is required to file pursuant to Rule 433(d) under the Securities Act has been, or will be, filed with the Commission in accordance with the requirements of the Securities Act and the applicable rules and regulations of the Commission thereunder. Each free writing prospectus that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or that was prepared by or on behalf of or used by the Company complies or will comply in all material respects with the requirements of Rule 433 under the Securities Act including timely filing with the Commission or retention where required and legending. Except for the free writing prospectuses, if any, identified in Schedule III hereto, and electronic road shows, if any, each furnished to the Representatives before first use and identified on Schedule III hereto, the Company has not prepared, used or referred to, and will not, without the Representative’s prior consent, prepare, use or refer to, any free writing prospectus.

There are no contracts or other documents required to be described in the Canadian Base Prospectus and the Canadian Preliminary Prospectus which have not been described or filed as required pursuant to Canadian Securities Laws.

(l) The financial statements of the Company (including all notes and schedules thereto) included or incorporated by reference in the Registration Statement, the Statutory Prospectus and the Final Prospectus present fairly the financial position of the Company and its consolidated subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified; and such financial statements and related schedules and notes thereto, and the unaudited financial information filed with the Commission as part of the Registration Statement, have been prepared in conformity with U.S. generally accepted

9

accounting principles (“U.S. GAAP”), consistently applied throughout the periods involved. The summary and selected financial data included in the Statutory Prospectus and Final Prospectus present fairly the information shown therein as at the respective dates and for the respective periods specified and have been presented on a basis consistent with the consolidated financial statements set forth in the Final Prospectus. No other financial statements or supporting schedules are required by the Securities Act or Canadian Securities Laws to be included in the Registration Statement or the Final Prospectus.

There has not been any “reportable event” (as that term is defined in National Instrument 51-102 Continuous Disclosure Obligations of the Canadian Securities Administrators) with any Auditor or any other prior auditor of the Company or any of its subsidiaries.

(o) The Company and each of its subsidiaries, including each entity (corporation, partnership, joint venture, association or other business organization) controlled directly or indirectly by the Company (each, a “subsidiary”), is duly organized, validly existing and in good standing (to the extent such concept exists in the relevant jurisdiction) under the laws of their respective jurisdictions of incorporation or organization (except where the failure of a subsidiary to be in good standing would not, individually or in the aggregate, have a Material Adverse Effect (as defined below)) and each such entity has all requisite power and authority to carry on its business as is currently being conducted as described in the Statutory Prospectus and the Final Prospectus, and to own, lease and operate its properties. All of the issued shares of capital stock of, or other ownership interests in, each subsidiary have been duly and validly authorized and issued and are fully paid and non-assessable and, except as described in each of the Statutory Prospectus and the Final Prospectus, are owned, directly or indirectly, by the Company, free and clear of any lien, charge, mortgage, pledge, security interest, claim, limitation on voting rights, equity, trust or other encumbrance, preferential arrangement, defect or restriction of any kind whatsoever. The Company and each of its subsidiaries is duly qualified to do business as a foreign corporation (to the extent applicable) and is in good standing (to the extent such concept

10

exists in the relevant jurisdiction) in each jurisdiction in which the nature of the business conducted by it or location of the assets or properties owned, leased or licensed by it requires such qualification, except for such jurisdictions where the failure to so qualify or be in good standing would not, individually or in the aggregate, have a material adverse effect on the assets, properties, condition, financial or otherwise, or in the results of operations, business affairs or business prospects of the Company and its subsidiaries considered as a whole (a “Material Adverse Effect”); and to the Company’s knowledge, no proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification.

(p) The Company and each of its subsidiaries has all requisite corporate power and authority, and all necessary authorizations, approvals, consents, orders, licenses, certificates and permits of and from all governmental or regulatory bodies or any other person or entity (collectively, the “Permits”), to own, lease and license its assets and properties and conduct its business, all of which are valid and in full force and effect, except where the lack of such Permits, individually or in the aggregate, would not have a Material Adverse Effect. The Company and each of its subsidiaries has fulfilled and performed in all material respects all of its obligations with respect to such Permits and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other material impairment of the rights of the Company thereunder. Except as may be required under the Securities Act and state and foreign Blue Sky laws or Canadian Securities Laws, and except for the approval of listing of the Firm Shares and Option Shares by the Nasdaq Global Select Market and the Toronto Stock Exchange, no other Permits are required to enter into, deliver and perform this Agreement and to issue and sell the Shares.

(q) The Company and each of its subsidiaries owns or possesses legally enforceable rights to use all patents, patent rights, inventions, trademarks, trademark applications, trade names, service marks, copyrights, copyright applications, licenses, know-how and other similar rights and proprietary knowledge (collectively, “Intangibles”) necessary for the conduct of its business, except where the lack of such Intangibles, individually or in the aggregate, would not have a Material Adverse Effect. Neither the Company nor any of its subsidiaries has received any, or is aware of any threatened, notice of infringement of or conflict with rights of others with respect to any Intangibles that have not been either settled or dismissed. None of the technology employed by the Company or any of its subsidiaries has been obtained or is being used by the Company or any of its subsidiaries in violation of any material contractual obligation binding on the Company or any of its subsidiaries or, to the Company’s knowledge, any of its or its subsidiaries’ officers, directors or employees or otherwise in violation of the rights of any persons.

(r) Except as described in each of the Statutory Prospectus and the Final Prospectus, the Company and each of its subsidiaries has good and marketable title to all property owned by it, in each case free and clear of all liens, encumbrances, claims, security interests and defects, except such as do not materially affect the value of such property and do not materially interfere with the use made or proposed to be made of such property by the Company and its subsidiaries.

Neither the Company nor any of its subsidiaries, if a subsidiary is a party, nor to the Company’s knowledge, any other party is in default in the observance or performance of any term or obligation to be performed by it under any such agreement, and no event has occurred which with notice or lapse of time or both would constitute such a default, in any such case which default or event, individually or in the aggregate, would have a Material Adverse Effect.

(w) This Agreement has been duly authorized, executed and delivered by the Company.

(x) Neither the execution, delivery and performance of this Agreement by the Company nor the consummation of any of the transactions contemplated hereby (including, without limitation, the issuance and sale by the Company of the Shares) will give rise to a right to terminate or accelerate the due date of any payment due under, or conflict with or result in the breach of any term or provision of, or constitute a default (or an event which with notice or lapse of time or both would constitute a default) under, or require any consent or waiver under, or result in the execution or imposition of any lien, charge or encumbrance upon any properties or assets of the Company or its subsidiaries pursuant to the terms of, any indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which either the Company or its subsidiaries or any of their properties or businesses is bound, or any franchise, license, permit, judgment, decree, order, statute, rule or regulation applicable to the Company or any of its subsidiaries or violate any provision of the charter or by-laws of the Company or any of its subsidiaries, except for such consents or waivers which have already been obtained and are in full force and effect.

Other than pursuant to outstanding share options and warrants, there are no statutory preemptive or other similar rights to subscribe for or to purchase or acquire any shares of Common Shares of the Company or any of its subsidiaries or any such rights pursuant to its certificate of incorporation or by-laws or any agreement or instrument to or by which the Company or any of its subsidiaries is a party or bound.

13

share of stock of the Company or any of its subsidiaries or any security convertible into, or exercisable or exchangeable for, such stock. The exercise price of each option to acquire Common Shares (each, a “Company Stock Option”) is no less than the fair market value of a share of Common Shares as determined on the date of grant of such Company Stock Option. All grants of Company Stock Options were validly issued and properly approved by the Board of Directors of the Company in material compliance with all applicable laws and the terms of the plans under which such Company Stock Options were issued and were recorded on the Company’s financial statements in accordance with U.S. GAAP, and no such grants involved any “back dating”, “forward dating,” “spring loading” or similar practices with respect to the effective date of grant. The Common Shares and the Shares conform in all material respects to all statements in relation thereto contained in the Registration Statement, the Statutory Prospectus and the Final Prospectus. All outstanding shares of capital stock of each of the Company’s subsidiaries have been duly authorized and validly issued, and are fully paid and non-assessable and are owned directly by the Company or by another wholly-owned subsidiary of the Company free and clear of any security interests, liens, encumbrances, equities or claims, other than those described in each of the Statutory Prospectus and the Final Prospectus.

Each director and executive officer of the Company listed on Schedule II hereto has delivered to the Representative his or her enforceable written lock-up agreement in the form attached to this Agreement as Exhibit A hereto (“Lock-Up Agreement”).

(aa) Except as described in each of the Statutory Prospectus and the Final Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject which, if determined adversely to the Company or any of its subsidiaries could individually or in the aggregate have a Material Adverse Effect; and, to the knowledge of the Company, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

(bb) All necessary corporate action has been duly and validly taken by the Company to authorize the execution, delivery and performance of this Agreement and the issuance and sale of the Shares by the Company.

(cc) Neither the Company nor any of its subsidiaries is involved in any labor dispute nor, to the knowledge of the Company, is any such dispute threatened, which dispute would have a Material Adverse Effect. The Company is not aware of any existing or imminent labor disturbance by the employees of any of its principal suppliers or contractors which would have a Material Adverse Effect. The Company is not aware of any threatened or pending litigation between the Company or its subsidiaries and any of its executive officers which, if adversely determined, could have a Material Adverse Effect and has no reason to believe that such officers will not remain in the employment of the Company.

(dd) No transaction has occurred between or among the Company and any of its officers, directors, affiliates or shareholders or any affiliate or affiliates of any such officer, director, affiliate or shareholder that is required to be described in and is not described in the Registration Statement, the Statutory Prospectus and the Final Prospectus.

(ee) Except for activities undertaken by the Underwriters in connection with this Agreement, the Company has not taken, nor will it take, directly or indirectly, any action designed to or which might reasonably be expected to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of the Common Shares or any security of the Company to facilitate the sale or resale of any of the Shares.

(ff) The Company and each of its subsidiaries has filed all Federal, state, provincial, local and foreign tax returns which are required to be filed through the date hereof, which returns are true and correct in all material respects or has received timely extensions thereof, and has paid all taxes shown on such returns and all assessments received by it to the extent that the same are material and have become due. There are no tax audits or investigations pending, which if adversely determined would have a Material Adverse Effect; nor are there any material proposed additional tax assessments against the Company or any of its subsidiaries.

(gg) The Shares have been duly authorized for quotation on the National Association of Securities Dealers Automated Quotation (“Nasdaq”) National Market System, subject to official notice of issuance.

(kk) Based on the evaluation of its disclosure controls and procedures, the Company is not aware of (i) any material weakness or significant deficiency in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize and report financial data or any material weaknesses in internal controls; or (ii) any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls.

(ll) Except as described in each of the Statutory Prospectus and the Final Prospectus, there are no material off-balance sheet arrangements (as defined in Item 303 of Regulation S-K) that have or are reasonably likely to have a material current or future effect on the Company’s financial condition, revenues or expenses, changes in financial condition, results of operations, liquidity, capital expenditures or capital resources.

Neither the Company nor any of its subsidiaries has been denied any insurance coverage which it has sought or for which it has applied.

(oo) Each approval, consent, order, authorization, designation, declaration or filing of, by or with any regulatory, administrative or other governmental body necessary in connection with the execution and delivery by the Company of this Agreement and the consummation of the transactions herein contemplated required to be obtained or performed by the Company (except such additional steps as may be required by the Financial Industry Regulatory Authority (“FINRA”) or may be necessary to qualify the Shares for public offering by the Underwriters under the state securities or Blue Sky laws) has been obtained or made and is in full force and effect.

Notwithstanding the foregoing, (i) the Company represents and warrants that each such grantee or purchaser or holder of such registered securities shall be subject to similar lockup restrictions as set forth on Exhibit A attached hereto and the Company shall enforce such rights and impose stop-transfer restrictions on any such sale or other transfer or disposition of such shares until the end of the applicable period and (ii) if (x) during the last 17 days of the 90-day period described in this Section 4(a)(viii), the Company issues an earnings release or material news or a material event relating to the Company occurs; or (y) prior to the expiration of such 90-day period, the Company announces that it will release earnings results during the 16 day period beginning on the last day of the 90-day period; the restrictions imposed under this Section 4(a)(viii) shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event; provided, however, that this sentence shall not apply if the research published or distributed on the Company is compliant under Rule 139 of the Securities Act and the Company’s securities are actively traded as defined in Rule 101(c)(1) of Regulation M of the Exchange Act.

(ix) On or before completion of this offering, the Company shall make all filings required under applicable securities laws and by the Nasdaq Global Market and the Toronto Stock Exchange (including any required registration under the Exchange Act).

The Company shall file any such Marketing Materials with the SEC pursuant to Rule 433(d) under the U.S. Securities Act on or before the day such Marketing Materials are first provided to any potential investor of Shares, unless an exemption is available from such filing requirement and the conditions to the availability of such exemption is satisfied. For purposes of this section, “Distribution” means “distribution” or “distribution to the public,” as the case may be, as those terms are defined under Canadian Securities Laws in any of the Qualifying Jurisdictions and “Marketing Materials”, “template version” and “comparables” has the meaning ascribed thereto in National Instrument 41-101 General Prospectus Requirements.

(xiii) Not to provide any potential investor in Canada with any other Marketing Materials (other than in connection with any broadly available road show) unless a template version of such Marketing Materials has been approved in writing by the Company and the Representative and filed by the Company with the Canadian Commissions on or before the day such Marketing Materials are first provided to any potential investor of Shares in Canada, unless an exemption is available from such filing requirements and the conditions to availability of such exemption is satisfied.

(c) The Company acknowledges and agrees that each of the Underwriters has acted and is acting solely in the capacity of a principal in an arm’s length transaction between the Company, on the one hand, and the Underwriters, on the other hand, with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor, agent or fiduciary to the Company or any other person. Additionally, the Company acknowledges and agrees that the Underwriters have not and will not advise the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company has consulted with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company or any other person with respect thereto, whether arising prior to or after the date hereof. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions have been and will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company.

The Company has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission, where required, legending and record keeping. The Company represents that is has satisfied and agrees that it will satisfy the conditions set forth in Rule 433 of the Rules to avoid a requirement to file with the Commission any Road Show.

5. Indemnification.

(a) The Company agrees to indemnify and hold harmless each Underwriter, its officers and employees, affiliates and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any and all losses, claims, damages and liabilities, joint or several (including any reasonable investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, or any of them, may become subject under the Securities Act, the Exchange Act or other federal, state or provincial law or regulation, at common law, under Canadian Securities Laws or otherwise, insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Registration Statement, the Statutory Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or any “issuer-information” filed or required to be filed pursuant to Rule 433(d) of the Rules, any amendment thereof or supplement thereto, or in any Blue Sky application or other information or other documents executed by the Company filed in any state or other jurisdiction to qualify any or all of the Shares under the securities laws thereof (any such application, document or information being hereinafter referred to as a “Blue Sky Application”) or which arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that such indemnity shall not inure to the benefit of any Underwriter (or any person controlling such Underwriter) on account of any losses, claims, damages or liabilities arising from the sale of the Shares to any person by such Underwriter if such untrue statement or omission or alleged untrue statement or omission was made in such Preliminary Prospectus, the Registration Statement, the Final Prospectus, the Statutory Prospectus, any Issuer Free Writing Prospectus or such amendment or supplement thereto, or in any Blue Sky Application in reliance upon and in conformity with the Underwriter Information. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

27

(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each director of the Company, and each officer of the Company who signs the Registration Statement, against any losses, claims, damages or liabilities to which such party may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Registration Statement or the Final Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Prospectus, the Registration Statement, the Statutory Prospectus or the Final Prospectus or any such amendment or supplement in reliance upon and in conformity with the Underwriter Information; provided, however, that the obligation of each Underwriter to indemnify the Company (including any controlling person, director or officer thereof) shall be limited to the amount of the underwriting discount and commissions applicable to the Shares to be purchased by such Underwriter hereunder.

(c) Any party that proposes to assert the right to be indemnified under this Section will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section, notify each such indemnifying party of the commencement of such action, suit or proceeding, enclosing a copy of all papers served. No indemnification provided for in Section 5(a) or 5(b) shall be available to any party who shall fail to give notice as provided in this Section 5(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was prejudiced by the failure to give such notice but the omission so to notify such indemnifying party of any such action, suit or proceeding shall not relieve it from any liability that it may have to any indemnified party for contribution or otherwise than under this Section. In case any such action, suit or proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and the approval by the indemnified party of such counsel, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses, except as provided below and except for the reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. The indemnified party shall have the right to employ its counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it which are different from or in addition to those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party) or (iii) the indemnifying party shall not have employed counsel to assume the defense of such action within a reasonable time after notice of the commencement thereof, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. An indemnifying party shall not be liable for any settlement of any action, suit, and proceeding or claim effected without its written consent, which consent shall not be unreasonably withheld or delayed.

28

6. Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 5(a) or 5(b) is due in accordance with its terms but for any reason is unavailable to or insufficient to hold harmless an indemnified party in respect to any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate losses, liabilities, claims, damages and expenses (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after deducting any contribution received by any person entitled hereunder to contribution from any person who may be liable for contribution) incurred by such indemnified party, as incurred, in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares pursuant to this Agreement or, if such allocation is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company on the one hand and the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 6, no Underwriter (except as may be provided in any Agreement Among Underwriters) shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 6, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of the Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 6, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 6. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent. The Underwriter’s obligations to contribute pursuant to this Section 6 are several in proportion to their respective underwriting commitments and not joint.

29

7. Termination.

(a) This Agreement may be terminated with respect to the Shares to be purchased on a Closing Date by the Representative by notifying the Company at any time at or before a Closing Date in the absolute discretion of the Representatives if: (i) there has occurred any material adverse change in the securities markets or any event, act or occurrence that has materially disrupted, or in the opinion of the Representative, will in the future materially disrupt, the securities markets or there shall be such a material adverse change in general financial, political or economic conditions or the effect of international conditions on the financial markets in the United States or Canada is such as to make it, in the judgment of the Representative, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (ii) there has occurred any outbreak or material escalation of hostilities or acts of terrorism or other calamity or crisis the effect of which on the financial markets of the United States or Canada is such as to make it, in the judgment of the Representative, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (iii) trading in the Shares or any securities of the Company has been suspended or materially limited or trading generally on the New York Stock Exchange, Inc., the NASDAQ Global Market or the Toronto Stock Exchange has been suspended or materially limited, or minimum or maximum ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities have been required, by any of said exchanges or by such system or by order of the Commission, the Canadian Commissions, FINRA, or any other governmental or regulatory authority; (iv) a banking moratorium has been declared by any state or federal authority or the applicable authorities of any of the Qualifying Jurisdictions; or (v) in the judgment of the Representative, there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Final Prospectus, any material adverse change in the assets, properties, condition, financial or otherwise, or in the results of operations, business affairs or business prospects of the Company and its subsidiaries considered as a whole, whether or not arising in the ordinary course of business.

(b) If this Agreement is terminated pursuant to any of its provisions, the Company shall not be under any liability to any Underwriter, and no Underwriter shall be under any liability to the Company, except that (y) if this Agreement is terminated by the Representative or the Underwriters because of any failure, refusal or inability on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and disbursements of their counsel, subject to the limitation on reimbursable expenses in Section 4(b)) incurred by them in connection with the proposed purchase and sale of the Shares or in contemplation of performing their obligations hereunder and (z) no Underwriter who shall have failed or refused to purchase the Shares agreed to be purchased by it under this Agreement, without some reason sufficient hereunder to justify cancellation or termination of its obligations under this Agreement, shall be relieved of liability to the Company, or to the other Underwriters, for damages occasioned by its failure or refusal.

30

8. Substitution of Underwriters. If any Underwriter shall default in its obligation to purchase on any Closing Date the Shares agreed to be purchased hereunder on such Closing Date, the Representative shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase such Shares on the terms contained herein. If, however, the Representative shall not have completed such arrangements within such 36-hour period, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Underwriters to purchase such Shares on such terms. If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided above, the aggregate number of Shares which remains unpurchased on such Closing Date does not exceed one-eleventh of the aggregate number of all the Shares that all the Underwriters are obligated to purchase on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such date and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default. In any such case, either the Representative or the Company shall have the right to postpone the applicable Closing Date for a period of not more than seven days in order to effect any necessary changes and arrangements (including any necessary amendments or supplements to the Registration Statement or Final Prospectus or any other documents), and the Company agrees to file promptly any amendments to the Registration Statement or the Final Prospectus which in the opinion of the Company and the Underwriters and their counsel may thereby be made necessary.

If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Company as provided above, the aggregate number of such Shares which remains unpurchased exceeds 10% of the aggregate number of all the Shares to be purchased at such date, then this Agreement, or, with respect to a Closing Date which occurs after the Firm Shares Closing Date, the obligations of the Underwriters to purchase and of the Company to sell the Option Shares to be purchased and sold on such date, shall terminate, without liability on the part of any non-defaulting Underwriter to the Company, and without liability on the part of the Company, except as provided in Sections 4(b), 5, 6 and 7. The provisions of this Section 8 shall not in any way affect the liability of any defaulting Underwriter to the Company or the non-defaulting Underwriters arising out of such default. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 8 with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

9. Miscellaneous. The respective agreements, representations, warranties, indemnities and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or the Company or any of their respective officers, directors or controlling persons referred to in Sections 5 and 6 hereof, and shall survive delivery of and payment for the Shares. In addition, the provisions of Sections 4(b), 5, 6 and 7 shall survive the termination or cancellation of this Agreement.

31

This Agreement has been and is made for the benefit of the Underwriters and the Company and their respective successors and assigns, and, to the extent expressed herein, for the benefit of persons controlling any of the Underwriters or the Company, and directors and officers of the Company, and their respective successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. The term “successors and assigns” shall not include any purchaser of Shares from any Underwriter merely because of such purchase.

Ladies and Gentlemen:

The undersigned, a holder of common shares (“Common Shares”), or rights to acquire Common Shares, of Westport Fuel Systems Inc. (the “Company”) understands that you, as Representative of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with the Company, providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule I to the Underwriting Agreement (the “Underwriters”), of shares of Common Shares of the Company (the “Securities”).
