Dear Sirs:

1. INTRODUCTION.

Ballard Power Systems Inc., a corporation organized under the Canada Business Corporations Act (the “Company”), proposes to issue and sell to the several Underwriters (defined below), pursuant to the terms and conditions of this Underwriting Agreement (this “Agreement”), an aggregate of 8,125,000 common shares, no par value per share (the “Common Shares”) of the Company (such number of Common Shares, the “Firm Shares”). The Company hereby confirms that the underwriters set forth in Schedule A hereto (the “Underwriters”) have acted as the Underwriters in accordance with the terms and conditions hereof. Cowen and Company, LLC (“Cowen”) is acting as the representative of the Underwriters and in such capacity is hereinafter referred to as the “Representative.”

The Company also proposes to issue and sell to the several Underwriters up to 1,218,750 additional Common Shares (the “Additional Shares”). The Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, such Additional Shares granted to the Underwriters as set forth below and in Section 2 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.”

The Underwriters may exercise their purchase right for Additional Shares in whole or from time to time in part by written notice from the Representative not later than thirty (30) days after the date of this Agreement. Any exercise notice shall specify the aggregate number of Additional Shares as to which the option is being exercised and the date on which such Additional Shares are to be purchased. Each purchase date must be at least two business days after the written notice is given and may not be earlier than the closing date for the Firm Shares or later than ten business days after the date of such notice. Additional Shares may be purchased hereby solely for the purpose of covering over-allotments made in connection with the offering

of the Firm Shares. Each day, if any, that Additional Shares are to be purchased is hereinafter referred to as an “Option Closing Date.”

On June 29, 2015, the Company entered into an Agreement and Plan of Merger in the form filed as an exhibit to the Company’s material change report, dated June 29, 2015 (the “Merger Agreement”) with BPC SubCo Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (“Merger Sub”), Protonex Technology Corporation, a Delaware corporation (“Protonex”), and Edward J. Stewart, as stockholder representative, pursuant to which Merger Sub will merge with and into Protonex (the “Merger”), on the terms and subject to the conditions set forth in the Merger Agreement, so that Protonex, as the surviving corporation, will become a wholly-owned subsidiary of the Company. As used in this Agreement, “Acquired Companies” shall refer to Protonex and each of its direct and indirect subsidiaries.

2. DELIVERY AND PAYMENT. On the basis of the representations, warranties and agreements of the Company herein contained, and subject to the terms and conditions set forth in this Agreement:

2.1 The Company agrees to issue and sell to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective number of Firm Shares set forth opposite such Underwriter’s name in Schedule A hereto at a purchase price (the “Purchase Price”) of U.S. $1.60 per Firm Share, being the price at which the Firm Shares are to be initially offered to the public, less a commission to the Underwriters of U.S. $0.104 per Firm Share. The Company has been advised by you that you propose to make a public offering of the Shares (the “Offering”) as soon after this Agreement has become effective as in your judgment is advisable. The Company is further advised by you that the Firm Shares are to be offered to the public initially at a price of U.S. $1.60 per Firm Share.

2.2 Payment of the Purchase Price for, and delivery of, the Firm Shares shall be made at the time and date of closing and delivery of the documents required to be delivered to the Underwriters pursuant to Sections 4 and 6 hereof shall be at 8:30 A.M., New York time, on July 7, 2015, or at such other time and date as the Representative and the Company determine pursuant to Rule 15c6-1(a) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (the “Closing Date”), at the office of Dorsey & Whitney LLP, Columbia Center, 701 Fifth Avenue, Suite 6100, Seattle, Washington 98101. On the Closing Date, the Company shall deliver the Firm Shares, which shall be registered in the name or names and shall be in such denominations as the Representative may request at least one (1) business day before the Closing Date, to the Underwriters, which delivery shall be made through the facilities of the Depository Trust Company’s DWAC system against delivery of the Purchase Price by the Underwriters to the Company by wire transfer of immediately available funds.

2.3 If any Additional Shares are to be purchased, the number of Additional Shares to be purchased by each Underwriter shall be the number of Additional Shares which bears the same ratio to the aggregate number of Additional Shares being purchased as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule A hereto bears to the aggregate number of Firm Shares being purchased from the Company by the several Underwriters, subject, however, to such adjustments to eliminate any fractional Common Shares as the Representative in its sole discretion shall make. Payment of the Purchase Price for, and delivery of, any Additional Shares shall be made at the Option Closing Date or at such other time and date as the Representative and the Company determine pursuant to Rule 15c6-1(a) under the Exchange Act. The Company shall deliver the Additional Shares, which shall be registered in the name or names and shall be in such denominations as the Representative may request at least one (1) business day before the Option Closing Date, to the Underwriters, which delivery shall be made through the facilities of the Depository Trust Company’s DWAC system against delivery of the Purchase Price by the Underwriters to the Company by wire transfer of immediately available funds. The Option Closing Date may be simultaneous with, but not earlier than, the Closing Date; and in the event that such time and date are simultaneous with the Closing Date, the term “Closing Date” shall refer to the time and date of delivery of the Firm Shares and Additional Shares.

2.4 Prior to either of the Closing Date or the Option Closing Date, the Company shall not, without the prior written consent of the Representative, solicit or accept offers to purchase Common Shares or securities convertible into, or exchangeable or exercisable for, Common Shares otherwise than through the Underwriters in accordance herewith, other than (i) the Company’s sale of the securities hereunder, (ii) the issuance by the Company of Common Shares or securities convertible into or exercisable or exchangeable for Common Shares to a strategic investor or in connection with the establishment of a joint venture or similar strategic relationship by the Company, in each case on an arm’s-length basis with an unaffiliated third party, (iii) the issuance of restricted share units, deferred share units or options to acquire Common Shares in a manner consistent with past practice pursuant to the Company’s Consolidated Share Option Plan effective as of June 2, 2009, Consolidated Share Distribution Plan effective as of June 2, 2009, Market Purchase RSU Plan, effective as of March 23, 2009 (such plans, together, the “Company’s Plans”) and the issuance of Common Shares pursuant to the valid exercises, redemptions or conversion of restricted share units, deferred share units or options outstanding on the date hereof.

The Company has satisfied the conditions of MI 11-102 for the deemed issuance of a receipt by the other Canadian Commissions for each of the Canadian Preliminary Base Prospectus and the Canadian Final Base Prospectus. 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 all applicable securities 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, the “Canadian Securities Laws”). The Company has prepared the Canadian Base Prospectus pursuant to the Canadian Securities Laws, including National Instruments 44-101 Short Form Prospectus Distributions and 44-102 Shelf Distributions (the “Shelf Procedures”).

The information, if any, included in the Canadian Prospectus Supplement that is omitted from the Canadian Base Prospectus, but that is deemed under the Shelf Procedures to be incorporated by reference into the Canadian Base Prospectus as of the date of the Canadian Prospectus Supplement, is referred to herein as the “Shelf Information.” The U.S. Prospectus Supplement and the Canadian Prospectus Supplement are hereinafter collectively sometimes referred to as the “Prospectus Supplements.”

The registration statement on Form F-10, including the exhibits thereto and the documents incorporated by reference therein and the U.S. Prospectus, as amended or supplemented in connection with the execution and delivery of this Agreement, is herein called the “Registration Statement.” The term “U.S. Prospectus” shall refer to the U.S. Base Prospectus, as supplemented by the U.S. Prospectus Supplement, including, in each case, the documents incorporated by reference therein. Any reference to any amendment or supplement to the Registration Statement or the U.S. Prospectus shall be deemed to refer to and include any documents filed with the Canadian Commissions and the Commission after the effectiveness of such Registration Statement or the date of such U.S. Prospectus and prior to the termination of the Offering and which are incorporated by reference in such Registration Statement or U.S. Prospectus. The term “Canadian Prospectus” shall refer to the Canadian Base Prospectus, as supplemented by the Canadian Prospectus Supplement, including, in each case, the documents incorporated by reference therein.

(aa) No labor disturbance or dispute with the employees of the Company or any of the Company’s subsidiaries exists or, to the Company’s knowledge, is threatened or imminent, and the Company is not aware of any existing or imminent labor disturbance by the employees of any of its or its subsidiaries’ principal suppliers, manufacturers, customers or contractors, that could reasonably be expected, singly or in the aggregate, to have a Material Adverse Effect. The Company is not aware that any key employee or significant group of employees of the Company and/or any of the Company’s subsidiaries plans to terminate employment with the Company or any of the Company’s subsidiaries.

(bb) The Company and its subsidiaries are in compliance with all Canadian federal, territorial and provincial laws, all United States federal, state and local and any other applicable foreign rules, laws and regulations relating to the use, treatment, storage and disposal of hazardous or toxic substances or waste and protection of health and safety or the environment which are applicable to their businesses (“Environmental Laws”), except where the failure to comply would not, singly or in the aggregate, have a Material Adverse Effect. There has been no storage, generation, transportation, handling, treatment, disposal, discharge, emission, or other release of any kind of toxic or other wastes or other hazardous substances by, due to, or caused by the Company or any of its subsidiaries (or, to the Company’s knowledge, any other entity for whose acts or omissions the Company or any of its subsidiaries is or may otherwise be liable) upon any of the property now or previously owned or leased by the Company or any of its subsidiaries, or upon any other property, in violation of any law, statute, ordinance, rule, regulation, order, judgment, decree or permit or which would, under any law, statute, ordinance, rule (including rule of common law), regulation, order, judgment, decree or permit, give rise to any liability, except for any violation or liability which would not have, singly or in the aggregate with all such violations and liabilities, a Material

Adverse Effect; and there has been no disposal, discharge, emission or other release of any kind onto such property or into the environment surrounding such property of any toxic or other wastes or other hazardous substances with respect to which the Company has knowledge, except for any such disposal, discharge, emission, or other release of any kind which would not have, singly or in the aggregate with all such discharges and other releases, a Material Adverse Effect. In the ordinary course of business, the Company and its subsidiaries conduct periodic reviews of the effect of Environmental Laws on their business and assets, in the course of which they identify and evaluate associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or Governmental Permits issued thereunder, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such reviews, the Company and its subsidiaries have reasonably concluded that such associated costs and liabilities would not have, singly or in the aggregate, a Material Adverse Effect.

The Company has no reason to believe that it and its subsidiaries will not be able to renew their existing insurance coverage as and when such coverage expires or to obtain comparable coverage from similar insurers as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not have a Material Adverse Effect. Neither the Company nor any of its subsidiaries has been denied any insurance coverage that they have sought or for which they have applied.

(ee) The Company and its subsidiaries each maintains a system of internal accounting and other controls (including “disclosure controls and procedures” and “internal controls over financial reporting” within the meaning of such terms under National Instrument 52-109 Certification of Disclosure In Issuers’ Annual and Interim Filings) sufficient to provide reasonable assurances that (i) transactions are executed in accordance with general or specific authorizations of management and the directors; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with IFRS and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as described in the General Disclosure Package, since the end of the Company’s most recent audited fiscal year, there has been (A) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (B) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(ff) The minute books of the Company and each of its subsidiaries that would be a “significant subsidiary” within the meaning of Rule 1-02(w) of Regulation S-X under the Exchange Act have been made available to the Underwriters and counsel for the Underwriters, and such books contain all minutes of meetings and all resolutions of the board of directors (including each board committee) and shareholders of such entity, (or analogous governing bodies and interest holders, as applicable) since the time of its respective incorporation or organization through the date of the latest meeting or resolution.

(gg) There is no franchise, lease, contract, agreement or document required by the Securities Act or applicable Canadian Securities Laws to be described in the General Disclosure Package and in the Prospectuses or a document incorporated by reference therein or to be filed as an exhibit to the Registration Statement or a document incorporated by reference therein which is not described or filed therein; and all descriptions of any such franchises, leases, contracts, agreements or documents contained in the Registration Statement or in a document incorporated by reference therein are accurate and complete descriptions of such documents in all material respects. Other than as described in the General Disclosure Package, no such franchise, lease, contract or agreement has been suspended or terminated for convenience or default by the Company or any of its subsidiaries or any of the other parties thereto, and neither the Company nor any of its subsidiaries has received notice nor does the Company have any other knowledge of any such pending or threatened suspension or termination, except for such pending or threatened suspensions or terminations that would not reasonably be expected to, singly or in the aggregate, have a Material Adverse Effect.

subsidiaries or any of their affiliates on the other hand, and there has been no related-party transaction involving the foregoing, which is required to be described in the General Disclosure Package and the Prospectuses or a document incorporated by reference therein and which is not so described.

Before amending the Registration Statement or amending or supplementing the U.S. Prospectus or the Canadian Prospectus in connection with the Offering, the Company will furnish the Representative with a copy of such proposed amendment or supplement and will not file such amendment or supplement to which the Representative reasonably objects.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company and its directors, its officers who signed the Registration Statement 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 (collectively, the “Company Indemnified Parties,” and each a “Company Indemnified Party”) against any loss, claim, damage, expense or liability whatsoever (or any action, investigation or proceeding in respect thereof), joint or several, to which such Company Indemnified Party may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, expense, liability, action, investigation or proceeding arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Securities Act, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) of the Securities Act, any Registration Statement or the Prospectuses, or in any amendment or supplement thereto, a material fact required to be stated therein or necessary to make the statements therein (with respect only to the Prospectuses in light of the circumstances in which they are made) not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters specifically for use therein, which information the parties hereto agree is limited to the Underwriters’ Information as defined in Section 16, and shall reimburse the Company Indemnified Party promptly upon demand for any legal fees or other expenses reasonably incurred by such party in connection with investigating or preparing to defend or defending against, settling, compromising or appearing as third party witness in connection with any such loss, claim, damage, liability, action, investigation or proceeding, as such fees and expenses are incurred. Notwithstanding the provisions of this Section 7(b), in no event shall any indemnity by any Underwriter under this Section 7(b) exceed the total discount and commission received by such Underwriter in connection with the Offering.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, investigation, proceeding or claim, the indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under this Section 7, notify such indemnifying party in writing of the commencement of that action, investigation, proceeding or claim; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced by such failure; and, provided, further, that the failure to notify an indemnifying party shall not relieve the indemnifying party from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such action, investigation, proceeding or claim shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense of such action, investigation, proceeding or claim with counsel reasonably satisfactory to the indemnified party (which counsel shall not, except with the written consent of the indemnified party, be counsel to the indemnifying party). After notice from the indemnifying party to the indemnified party of its election to assume the defense of such action, investigation, proceeding or claim, except as provided herein, the indemnifying party shall not be liable to the indemnified party under Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense of such action, investigation, proceeding or claim other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action, investigation, proceeding or claim and to participate in the defense of such action, investigation, proceeding or claim, but the fees and expenses of such counsel (other than reasonable costs of investigation) shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized in writing by the Company in the case of a claim for indemnification under Section 7(a) or by the Representative in the case of a claim for indemnification under Section 7(b), (ii) such indemnified party shall have been advised by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party has failed to assume the defense of such action, investigation, proceeding or claim and employ counsel reasonably satisfactory to the indemnified party within a reasonable period of time after notice of the commencement of the action, investigation, proceeding or claim, or the indemnifying party does not diligently defend the action, investigation, proceeding or claim after assumption of the defense, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of (or, in the case of a failure to diligently defend the action, investigation, proceeding or claim after assumption of the defense, to continue to defend) such action, investigation, proceeding or claim on behalf of such indemnified party and the indemnifying party shall be responsible for legal or other expenses subsequently incurred by such indemnified party in connection with the defense of such action, investigation, proceeding or claim; provided, however, that the indemnifying party shall not, in connection with any one such action, investigation, proceeding or claim or separate but substantially similar or related

actions, investigations, proceedings or claims in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any time for all such indemnified parties (in addition to any local counsel), which firm shall be designated in writing by the Representative if the indemnified parties under this Section 7 consist of any Underwriter Indemnified Party or by the Company if the indemnified parties under this Section 7 consist of any Company Indemnified Parties. Subject to this Section 7(c), the amount payable by an indemnifying party under Section 7 shall include, but not be limited to, (x) reasonable legal fees and expenses of counsel to the indemnified party and any other reasonable expenses in investigating, or preparing to defend or defending against, or appearing as a third party witness in respect of, or otherwise incurred in connection with, any action, investigation, proceeding or claim, and (y) all amounts paid in settlement of any of the foregoing. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of judgment with respect to any pending or threatened action, investigation, proceeding or any claim whatsoever, in respect of which indemnification or contribution could be sought under this Section 7 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party in form and substance reasonably satisfactory to such indemnified party from all liability arising out of such action, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. Subject to the provisions of the following sentence, no indemnifying party shall be liable for settlement of any pending or threatened action, investigation, proceeding or claim whatsoever that is effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with its written consent, if its consent has been unreasonably withheld or delayed or if there be a judgment for the plaintiff in any such matter, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, if at any time an indemnified party shall have requested that an indemnifying party reimburse the indemnified party for reasonable fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated herein effected without its written consent if (i) such settlement is entered into more than sixty (60) days after receipt by such indemnifying party of the request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party under Section 7(a) or Section 7(b), then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid, payable or otherwise incurred by such indemnified party as a result of such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof), as incurred, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and

the Underwriters on the other hand from the Offering, or (ii) if the allocation provided by clause (i) of this Section 7(d) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) of this Section 7(d) but also the relative fault of the Company on the one hand and the Underwriters on the other with respect to the statements, omissions, acts or failures to act which resulted in such loss, claim, damage, expense or liability (or any action, investigation or proceeding in respect thereof) as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other with respect to the Offering shall be deemed to be in the same proportion as the total net proceeds from the Offering under this Agreement (before deducting expenses) received by the Company bear to the total underwriting discount and commission received by the Underwriters in connection with the Offering, in each case as set forth in the table on the cover page of the Prospectuses. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement, omission, act or failure to act; provided that the parties hereto agree that the written information furnished to the Company by or on behalf of the Underwriters for use in any Preliminary Prospectus, any Registration Statement or the Prospectus, or in any amendment or supplement thereto, consists solely of the Underwriter’s Information as defined in Section 16. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage, expense, liability, action, investigation or proceeding referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, preparing to defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. Notwithstanding the provisions of this Section 7(d), no Underwriter shall be required to contribute any amount in excess of the total discount and commission received by such Underwriter in connection with the Offering, less the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement, omission or alleged omission, act or alleged act or failure to act or alleged failure to act. 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.

8. TERMINATION.

The obligations of the Underwriters hereunder may be terminated by the Representative, in its absolute discretion by notice given to the Company prior to delivery of and payment for the

Shares if, prior to that time, any of the events described in Sections 6(j), 6(k), or 6(l) have occurred or if the Underwriters shall decline to purchase the Shares for any other reason permitted under this Agreement.

The Company acknowledges and agrees that:

(a) The Underwriters’ responsibility to the Company is solely contractual in nature, the Underwriters have been retained solely to act as underwriters in connection with the Offering and no fiduciary, advisory or agency relationship between the Company and the Underwriters has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Underwriters have advised or are advising the Company on other matters;

(b) The price of the Shares set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Underwriters, and the Company is capable of evaluating and understanding, and understands and accepts, the terms, risks and conditions of the transactions contemplated by this Agreement;

Ballard Announces Pricing of U.S. Offering

For Immediate Release — July 1, 2015

VANCOUVER, CANADA — Ballard Power Systems (NASDAQ: BLDP; TSX: BLD) has announced that it has priced an underwritten offering (“Offering”) of 8,125,000 common shares at a price of U.S. $1.60 per share, for gross Offering proceeds of approximately U.S. $13.0 million.

The net proceeds to Ballard from the Offering are expected to be approximately U.S. $11.8 million, after deducting underwriting discounts, commissions and other estimated Offering expenses. The Offering is expected to close on or about July 7, 2015, subject to customary closing conditions.

Ballard has also granted the underwriters of the Offering a 30-day option to purchase up to an additional 15% of the common shares offered in the Offering to cover overallotments, if any.

Cowen and Company is acting as the sole bookrunner for the Offering. Roth Capital Partners, Lake Street Capital Markets and H.C. Wainwright & Co. are acting as co-managers for the Offering.

Ballard expects to use the net proceeds from the Offering for working capital and other general corporate purposes, including the acquisition of, or investment in, companies, technologies, products or assets that complement Ballard’s business.

The Offering is being made in the United States only under Ballard’s short form Canadian base shelf prospectus (“Prospectus”), dated May 21, 2014, which has been filed with the Canadian securities regulators in each of the provinces and territories of Canada, except Quebec, and the corresponding shelf registration statement on Form F-10, which has been filed with the Securities and Exchange Commission (SEC) under the Multijurisdictional Disclosure System (MJDS) and was declared effective by the SEC on May 22, 2014. A prospectus supplement relating to, and describing the terms of, the Offering will be filed with the British Columbia Securities Commission on a non-offering basis, and with the SEC under the MJDS, and once filed will be available at www.sec.gov and www.sedar.com.

In connection with the offering, Ballard disclosed in the prospectus supplement that it anticipates its second quarter 2015 revenue to be in the range of $10.6 to $11.5 million, and gross margins to be lower than the previous quarter. Ballard also disclosed that it estimates that cash reserves will be between $38.0 and $40.0 million at the end of the second quarter.
