PRELIMINARY—SUBJECT TO COMPLETION—DATED AUGUST 11, 2015

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

To the Stockholders of Protonex Technology Corporation:

The board of directors of Protonex Technology Corporation, a Delaware corporation (“Protonex”), has unanimously adopted a resolution approving an agreement and plan of merger (the “Merger Agreement”) in which Ballard Power Systems Inc., a Canadian corporation (“Ballard”), will acquire all of the issued and outstanding shares of Protonex common stock through a transaction (the “Merger”) pursuant to which BPC SubCo Inc. (“Merger Sub”), a wholly-owned subsidiary of Ballard, will merge with and into Protonex, with Protonex surviving as a wholly-owned subsidiary of Ballard, and Ballard will issue its common shares in exchange for all of the issued and outstanding shares of Protonex common stock. Protonex is sending you the accompanying proxy statement/prospectus to notify you of a special meeting of Protonex stockholders being held to vote on the adoption of the Merger Agreement, the Merger and related matters and to ask you to vote at the special meeting in favor of the approval of the Merger Agreement and the Merger.

If the Merger Agreement is approved by Protonex’s stockholders and the Merger is completed, you will be entitled to receive approximately 0.1562 of a Ballard common share for each share of Protonex common stock that you hold as of the effective time of the Merger.

Ballard is a Canadian public company incorporated under the Canada Business Corporations Act, as amended (the “CBCA”) and its common shares trade on the Toronto Stock Exchange (the “TSX”) under the symbol “BLD” and on the NASDAQ Stock Market, LLC (“NASDAQ”) under the symbol “BLDP.”

For a discussion of risk factors that you should consider in evaluating the Merger and the other matters on which you are being asked to vote, see “Risk Factors” beginning on page 21 of the enclosed proxy statement/prospectus. The market price of Ballard common shares will continue to fluctuate following the date of the stockholder vote on the Merger proposal at the special meeting. Consequently, at the time of the stockholder vote, the value of the Merger consideration will not yet be determined. Based on the range of closing prices of Ballard common shares on the NASDAQ, during the period from June 26, 2015, the last trading day before public announcement of the execution of the Merger Agreement, through August 10, 2015, the last full trading day before the date of this proxy statement/prospectus, the Merger consideration represented a value ranging from a low of approximately U.S. $1.21 to a high of approximately U.S. $2.23 for each share of Ballard common stock.

Protonex cannot complete the Merger without the approval of holders of a majority of the outstanding shares of its common stock entitled to vote at the special meeting, although certain Protonex stockholders holding approximately 56% of the outstanding shares of Protonex common stock have agreed pursuant to support agreements to vote their shares in favor of the Merger. A failure to vote on the proposal to approve the Merger has the same effect as a vote by you “AGAINST” the approval of the Merger. Therefore, Protonex urges you to take the time to vote by following the instructions on your proxy card regardless of whether you plan to attend the special meeting.

The special meeting will be held at the offices of Protonex, 153 Northboro Road, Southborough, Massachusetts 01772-1034, United States on September 15, 2015, at 10:00 a.m. Eastern Daylight Time. Notice of the special meeting and the related proxy statement are enclosed.

Whether or not you plan to attend the special meeting, please complete, sign, date, and return the enclosed proxy card as soon as possible to ensure your representation at the special meeting. We have provided a postage-paid envelope for your convenience. If you plan to attend the special meeting and prefer to vote in person, you may still do so even if you have already returned your proxy card.

If you are a stockholder of record (that is, if your stock is registered with Protonex in your own name), then you may vote by: (i) signing and dating your proxy card and mailing it in the enclosed, prepaid and addressed envelope; or (ii) attending the special meeting and voting in person.

If your shares are registered in the name of a broker, bank, dealer or other nominee, then you are the beneficial owner of shares held in street name and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the special meeting. As a beneficial owner, you have the right to direct your broker, bank or other nominee on how to vote the shares in your account. As a beneficial owner, you are also invited to attend the special meeting; however, since you are not the stockholder of record, you may not vote your shares in person at the special meeting unless you request and obtain a valid proxy from your broker, bank, dealer or other nominee.

On behalf of Protonex, we look forward to seeing our stockholders at the special meeting and we thank you for your support.

The Protonex board of directors unanimously recommends that you vote “FOR” the proposal to adopt and approve the Merger Agreement and the Merger.

Sincerely, |
Paul Osenar |
President |

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND THE MERGER

The following are answers to certain questions that you may have regarding the special meeting and the Merger. We urge you to read carefully the remainder of this proxy statement/prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the appendices to, and the documents incorporated by reference in, this proxy statement/prospectus.

GENERAL

Q: WHY AM I RECEIVING THIS PROXY STATEMENT/PROSPECTUS?

A: This document serves as both a proxy statement of Protonex and prospectus of Ballard. As a proxy statement, it is being provided to Protonex’s stockholders in connection with the solicitation of proxies for the Protonex special meeting at which Protonex stockholders will be asked to vote on the proposal set forth in the Notice of Special Meeting of Protonex stockholders.

It is a prospectus because Ballard is offering to issue its common shares in exchange for shares of Protonex common stock upon completion of the Merger.

THE MERGER

Q: WHAT IS THE MERGER?

A: On June 29, 2015, Protonex entered into the Merger Agreement with Ballard, Merger Sub, and Edward J. Stewart, as the stockholder representative, pursuant to which Merger Sub will merge with and into Protonex on the terms and subject to the conditions set forth in the Merger Agreement, which transaction we refer to as the Merger, so that Protonex, as the surviving corporation, will become a wholly-owned subsidiary of Ballard.

Q: WHY ARE BALLARD AND PROTONEX PROPOSING TO MERGE?

A: The boards of directors of Ballard and Protonex are proposing to merge because they believe that the combination strengthens and is in the best interests of both companies and their respective stockholders. Please see “The Merger Proposal—Recommendations of Protonex’s Board of Directors; Protonex’s Reasons for the Transaction” at page 42 for the various factors considered by the Protonex board of directors in unanimously recommending that Protonex stockholders vote “FOR” the proposal to adopt the Merger Agreement and approve the Merger.

Q. WHAT WILL HAPPEN IN THE MERGER?

A. At the closing of the Merger, Merger Sub will merge with and into Protonex, so that Protonex, as the surviving corporation, will become a wholly-owned subsidiary of Ballard. In exchange for shares of Protonex common stock, the Protonex stockholders will receive Ballard common shares. As a result of the Merger, Ballard will own all of the issued and outstanding securities of Protonex and former Protonex stockholders will not have any direct equity ownership interest in the surviving corporation. See “Merger Agreement” on page 56.

Q: AS A PROTONEX STOCKHOLDER, WHAT WILL I RECEIVE IN THE MERGER?

A: Each Protonex stockholder will be entitled to receive approximately 0.1562 of a Ballard common share for each share of Protonex common stock currently held upon completion of the Merger. Following the completion of the Merger, it is expected that the former Protonex stockholders will own, by virtue of the exchange of their shares of Protonex common stock for Ballard shares, approximately 7.3% of the total Ballard common shares (based on the number of common shares of each of Protonex and Ballard outstanding as of the date of this proxy statement/prospectus). For more information on the calculation of the exchange ratio, please see “Merger Agreement—Conversion of Securities in the Merger” on page 57.

Table of Contents

Q: WHAT IS THE VALUE OF THE MERGER CONSIDERATION?

A: The Ballard common shares are traded on the TSX and the NASDAQ under the symbols “BLD” and “BLDP,” respectively. Because Ballard will issue a fixed number of Ballard common shares in exchange for each Protonex common share, the value of the Merger consideration that Protonex stockholders will receive will depend on the price per share of Ballard common shares at the time the Merger is completed. That price will not be known at the time of the special meeting and may be less or more than the current price or the price at the time of the special meeting. Based on the closing sale price of a Ballard common share on the NASDAQ of U.S. $1.33 on the last business day before the date of this proxy statement/prospectus, which may be more or less than the price at the closing of the Merger, and the actual level of Protonex’s net debt and transaction expenses, the consideration per share of Protonex common stock is approximately U.S. $0.2077.

Q: WHAT WILL HAPPEN TO MY PROTONEX OPTIONS OR WARRANTS?

A: In accordance with the Merger Agreement and Protonex’s 2003 Stock Incentive Plan and 2013 Stock Incentive Plan, holders of options to purchase Protonex common stock must exercise such options by the fifth business day prior to the special meeting of Protonex stockholders, or their options will be cancelled. In addition, under the Merger Agreement, Protonex has agreed to cause all outstanding warrants to purchase Protonex common stock to be exercised or terminated prior to the effective time of the Merger. Ballard will not assume any Protonex options, warrants or other derivative securities in connection with the Merger, and you will receive no Merger consideration in exchange for such securities. Any Protonex options or warrants duly exercised for shares of Protonex common stock prior to the effective time of the Merger will be entitled to the Merger consideration for their shares of common stock held at the effective time.

Q: ARE THE COMMON SHARES TO BE RECEIVED BY THE PROTONEX STOCKHOLDERS FREELY TRADEABLE UPON ISSUANCE?

A: Yes, all Ballard common shares that each Protonex stockholder receives in the Merger will be listed on the TSX and the NASDAQ and will be freely transferable under Canadian and U.S. securities laws unless a stockholder is deemed an affiliate of Protonex immediately prior to the Merger or an affiliate of Ballard following the Merger for purposes of U.S. securities laws or a control person of Ballard following the Merger for purposes of Canadian securities laws. This proxy statement/prospectus does not register the resale of Ballard common shares held by affiliates.

Furthermore, all of the Protonex stockholders that executed the support agreements (the “Supporting Stockholders”) (as described in “Ancillary Agreements—Support Agreement”) agreed that the Ballard common shares to be received by the Supporting Stockholders in the Merger are all subject to lock-up restrictions, which restrictions will lapse with respect to one-half of such Ballard common shares at the six and 12-month anniversaries of the closing date of the Merger. Each Supporting Stockholder agrees not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares during the lock-up period.

Q: WHAT IS THE ESCROW?

A: Ballard will deposit approximately 628,732 of the common shares, or approximately 5.6% of the total Merger consideration, to be issued to the Supporting Stockholders in connection with the Merger into an escrow account maintained by U.S. Bank, National Association. These common shares will be used to cover indemnification claims by the Ballard pursuant to the terms of the Merger Agreement, which shares will be released 12 months after the closing of the Merger, subject to any then-pending claims. See “Ancillary Agreements — Escrow Agreement” starting on page 69.

Q: DO PERSONS INVOLVED IN THE MERGER HAVE INTERESTS THAT MAY CONFLICT WITH MINE AS A PROTONEX STOCKHOLDER?

A: Yes. These interests include:

Table of Contents

· change of control bonus payments to be made to certain executive officers of Protonex;

· the acceleration of vesting of certain options held by certain directors and executive officers of Protonex; and

· the continued indemnification and directors’ and officers’ insurance coverage of current Protonex directors and officers following the Merger.

See “The Merger Proposal — Interests of Certain Protonex Directors, Officers and Affiliates in the Merger” on page 43.

Q: ARE THERE ANY CONDITIONS TO THE CLOSING OF THE MERGER?

A: Ballard’s and Protonex’s obligations to complete the Merger depend on a number of conditions being met. These include, among others:

· the approval of the stockholders of Protonex holding a majority of the votes cast at the special meeting;

· receipt or filing of all waiting period expirations or terminations, consents, clearances, waivers, approvals and authorizations of, any governmental authority or third-party under any applicable antitrust, competition or Merger control laws required to be made or obtained by Protonex, Ballard, Merger Sub or any of their subsidiaries to consummate the Merger shall have been made or obtained;

· the absence of any judgment, order, or law which prohibits, materially restricts, makes illegal or enjoins the consummation of the Merger;

· the effectiveness of the registration statement for the Ballard common shares to be issued in the Merger and the approval for listing of such shares on the TSX and the NASDAQ;

· subject to certain limitations and exceptions, the accuracy of the other party’s representations and warranties and the performance in all material respects of its covenants in the Merger Agreement;

· the number of dissenting shares held by stockholders of Protonex who have exercised appraisal rights must comprise less than 5% of the issued and outstanding shares of Protonex common stock;

· the execution of certain ancillary agreements;

· each party’s receipt of an opinion from outside legal counsel that is reasonably acceptable and dated as of the closing date of the Merger to the effect that, on the basis of the facts, representations and assumptions set forth or referred to in such opinion, the Merger should qualify for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”);

· evidence of the adoption and approval by Ballard and Ballard Power Corporation, as the sole stockholder of Merger Sub of the Merger Agreement, the Merger and the other transactions contemplated thereby;

· executed resolutions of Protonex’s board of directors authorizing the termination of all of Protonex’s unexercised stock options prior to Closing;

· the execution of employment agreements by certain key employees of Protonex;

· certain actions with respect to the waiver or approval of “parachute payments”, if applicable; and

· the absence of any material adverse change with respect to the business and affairs of Protonex (in the case of Ballard).

Table of Contents

Where permitted by applicable law and the Merger Agreement, either of Ballard or Protonex could choose to waive a condition to its respective obligation to complete the Merger even when that condition has not been satisfied. See “Merger Agreement—Conditions to the Consummation of the Merger” on page 64.

Q: IS PROTONEX OR BALLARD PROHIBITED FROM SOLICITING OTHER OFFERS?

A: The Merger Agreement contains detailed provisions that prohibit Protonex and its stockholders, and their respective representatives (including investment bankers, attorneys and accountants) from taking any action to directly or indirectly solicit or engage in discussions or negotiations with any person or group concerning any sale of all or a portion of Protonex’s assets, or of any capital stock of Protonex, or any merger, consolidation, liquidation, dissolution or similar transaction involving Protonex. Protonex has agreed to advise any prospective purchaser or soliciting party, by written notice of the terms of the no solicitation provisions and promptly notify Ballard if any such offer, or any inquiry or contact with any person is made. Protonex has also agreed not to release any third party from, or waive any provision of, any confidentiality or standstill agreement to which Protonex is a party. Notwithstanding the foregoing, if Protonex has received an alternative transaction proposal on which its board of directors has determined, in good faith, a failure to act would be a breach of the director’s fiduciary duties, then with prior written notice to Ballard, Protonex may enter into a customary confidentiality agreement, share non-public information and engage in discussions with the person making such proposal.

Either Ballard or Protonex may be obligated to pay to the other party a termination fee of U.S.$200,000 in certain circumstances if the Merger Agreement is terminated. If Protonex terminates the agreement to pursue a superior proposal, Protonex will be obligated to pay Ballard a termination fee of U.S.$1,500,000, plus all fees and expenses incurred by Ballard. See “Merger Agreement—No Solicitation” and “Merger Agreement—Termination Amount” beginning on pages 64 and 68, respectively.

Q: ARE THERE ANY STOCKHOLDERS ALREADY COMMITTED TO VOTE IN FAVOR OF THE MERGER?

A: Yes. Pursuant to support agreements, all of the Supporting Stockholdings, including the directors and officers of Protonex and certain major stockholders, have agreed to vote their shares of Protonex common stock representing approximately % of the outstanding shares of Protonex as of the record date in favor of the Merger at the special meeting. For a more complete description of the support agreements, see “Ancillary Agreements—Support Agreement” beginning on page 68 of this proxy statement/prospectus. The form of support agreement is also attached to this proxy statement/prospectus as Appendix B.

Q: WHAT ARE THE SUPPORT AGREEMENTS?

A: In connection with the execution of the Merger Agreement, certain Protonex stockholders, who we refer to as the Supporting Stockholders, entered into support agreements with Ballard, pursuant to which they have agreed, among other things, to vote all of their shares of capital stock of Protonex in favor of the approval of the Merger pursuant to the Merger Agreement and the other transactions contemplated thereby, to vote against any action that would reasonably likely result in a material breach of Protonex under the Merger Agreement, and to vote against any alternative transactions. The support agreements also generally prohibit the Supporting Stockholders from transferring their shares prior to the consummation of the Merger. The support agreements will terminate upon the termination of the Merger Agreement in accordance with its terms. The support agreements provide for the vote of a sufficient number of shares of Protonex to adopt the Merger Agreement and approve the Merger contemplated thereby under Delaware law and Protonex’s organizational documents. For a further description of the support agreements, see the section entitled “Ancillary Agreements—Support Agreement” beginning on page 68.

Q: WHAT ARE THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO PROTONEX STOCKHOLDERS?

The Merger is intended to qualify as a reorganization within the meaning of Section 368(a) of the Code, with no gain or loss recognition to U.S. holders of Protonex common stock (other than a U.S. holder of

4

Table of Contents

Protonex common stock who is a “five-percent transferee shareholder” within the meaning of the rules under Treasury regulations Section 1.367(a)-3(c) and who does not file a gain recognition agreement with the U.S. Internal Revenue Service, or the IRS) for U.S. federal income tax purposes. It is a condition to the closing of the Merger that, at the effective time of the Merger, outside legal counsel will deliver an opinion to Protonex and Ballard to the effect that, for U.S. federal income tax purposes, the Merger should qualify as a reorganization within the meaning of Section 368(a) of the Code. If the conclusions in the tax opinions were to be challenged by the Internal Revenue Service, which we refer to as the “IRS,” and such challenge were to be sustained, a U.S. holder of Protonex common stock would recognize gain (and might not be allowed to recognize loss) in the Merger based on the amount such U.S. holder realizes in the Merger.

You should consult your own tax advisor to determine the particular tax consequences to you of the Merger. The foregoing description of U.S. federal income tax consequences of the Merger to stockholders is qualified in its entirety by the longer form discussion under “The Merger Proposal—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 46 and “The Merger Proposal—Ownership and Disposition of Ballard Common Shares” beginning on page 47. Neither Protonex nor Ballard has sought or obtained a ruling from the IRS regarding any of the tax consequences of the Merger. Accordingly, there can be no assurance that the IRS will not challenge such tax treatment of the Merger or that the U.S. courts will uphold such tax treatment in the event of an IRS challenge.

Q: WHEN IS THE MERGER EXPECTED TO BE COMPLETED?

A: Protonex and Ballard are working towards completing the Merger as quickly as possible and it is currently anticipated that the Merger will be completed by the end of the third quarter of calendar year 2015. However, there can be no assurances that the Merger will be completed at all or, if completed, that it will be completed within such timeframe. The exact timing and likelihood of completion of the Merger cannot be predicted because the Merger is subject to certain conditions, including the receipt of regulatory approvals. Neither Protonex nor Ballard is obligated to complete the Merger unless and until the closing conditions in the Merger Agreement have been satisfied or waived.

Q: HOW WILL BALLARD BE MANAGED AFTER THE CLOSING OF THE MERGER?

A: Ballard’s executive officers and directors are not anticipated to change as a result of the Merger. See “The Merger Proposal — Directors and Management of Ballard Following the Merger” on page 54. Before the closing of the Merger, Ballard or one of its affiliates intends to enter into employment agreements with certain of Protonex’s employees, effective as of the effective time of the Merger. The directors of Protonex will resign as of the effective time of the Merger.

Q: WHAT HAPPENS IF THE MERGER IS NOT COMPLETED?

A: If the Merger is not completed, Protonex stockholders will not receive any consideration for their shares of Protonex common stock in connection with the Merger. Instead, Protonex will remain an independent company. Under specified circumstances, the terminating party may be required to pay the non-terminating party a fee of $200,000 with respect to the termination of the Merger Agreement; provided that, if Protonex terminates the Merger Agreement to pursue a superior proposal, Protonex will be required to pay Ballard a fee of $1,500,000, plus Ballard’s fees and expenses, as described under the section entitled “Merger Agreement—Termination Amount” beginning on page 68.

Q: WHAT WILL HAPPEN TO MY SHARE CERTIFICATES AND WHERE SHOULD I SEND MY SHARE CERTIFICATES?

A: At the effective time of the Merger, unless you properly exercise and perfect your appraisal rights, your shares of Protonex common stock will convert into the right to receive Ballard common shares and you will no longer be a stockholder of Protonex. You will receive written instructions and a letter of transmittal, and you will use these documents to exchange your Protonex share certificates for certificates representing your Ballard common shares. Each person who submits the necessary documentation is entitled to receive the

5

Table of Contents

Merger consideration of approximately 0.1562 Ballard common shares for each share of Protonex common stock. For more information see “Merger Agreement—Exchange of Protonex Stock Certificates for the Merger Consideration” on page 59.

Q: SHOULD I SEND IN MY PROTONEX SHARE CERTIFICATES NOW?

A: No. You should not send in your Protonex share certificates at this time. The exchange agent to be appointed by Ballard, Computershare Investor Services Inc., will mail you information within three business days following the effective time. Protonex stockholders who hold their shares in certificated form will need to exchange their Protonex share certificates for the Ballard common shares provided for in the Merger Agreement upon completion of the Merger. Ballard will send Protonex stockholders written instructions and a letter of transmittal for exchanging Protonex share certificates at that time. Protonex stockholders who hold their shares in book-entry form, if any, will also receive written instructions for exchanging their shares after the Merger is completed.

Q: DO PROTONEX STOCKHOLDERS HAVE APPRAISAL RIGHTS IN CONNECTION WITH THE MERGER?

A: Yes. Under Delaware law, holders of Protonex common stock that meet certain requirements will have the right to dissent from the Merger and obtain payment in cash for the fair value of their shares of Protonex common stock, as determined by the Delaware Chancery Court, rather than the Merger consideration. To exercise appraisal rights, Protonex stockholders must strictly follow the procedures prescribed by Delaware law. These procedures are summarized under the section entitled “The Merger Proposal — Appraisal Rights of Holders of Protonex Common Stock” beginning on page 52. In addition, the text of the applicable appraisal rights provisions of Delaware law is included as Appendix C to this proxy statement/prospectus.

Q: ARE THERE RISKS ASSOCIATED WITH THE MERGER, BALLARD, PROTONEX OR THE COMBINED COMPANY OF WHICH HOLDERS OF PROTONEX COMMON STOCK SHOULD BE AWARE?

A: Yes. You should read the section entitled “Risk Factors” beginning on page 21 and the risk factors set forth in Ballard’s Annual Report on Form 40-F for the year ended December 31, 2014, incorporated by reference herein.

THE SPECIAL MEETING

Table of Contents

Q: WHAT BUSINESS WILL OCCUR AT THE MEETING?

A: Protonex stockholders are voting on a proposal to adopt and approve the Merger Agreement and the Merger and will vote on such other matters as may be properly brought before the special meeting. The approval by the majority of Protonex stockholders of the proposal to approve and adopt the Merger Agreement is required by Delaware law and is a condition to the completion of the Merger.

Q: HOW DOES THE PROTONEX BOARD OF DIRECTORS RECOMMEND THAT I VOTE?

A: Protonex’s board of directors unanimously recommends that you vote your shares: “FOR” the proposal to adopt and approve the Merger Agreement and the Merger.

Q: WHO IS ENTITLED TO VOTE?

A: Holders of record of Protonex common stock at the close of business on August 11, 2015 which is the date that the board of directors has fixed as the record date for the special meeting, are entitled to notice of, and to vote at, the Protonex special meeting. As of the record date, there were 64,978,500 outstanding shares of Protonex common stock.

Q: WHAT CONSTITUTES A QUORUM?

A: The holders of one-third of Protonex’s common stock outstanding and entitled to vote, represented at the special meeting in person or by proxy, shall constitute a quorum for the transaction of business. Abstentions and broker non-votes, if any, will be included in determining the number of shares present at the meeting for the purpose of determining the presence of a quorum.

Q: HOW MANY VOTES MAY A HOLDER OF COMMON STOCK CAST?

A: Holders of Protonex common stock are entitled to one vote at the special meeting for each share of common stock held that was issued and outstanding as of the record date.

Q: WHAT VOTE IS REQUIRED TO APPROVE THE MERGER PROPOSAL?

A: The adoption and approval of the Merger Agreement and the Merger requires the affirmative vote of the holders of a majority of the shares of Protonex common stock issued and outstanding on the record date, and entitled to vote at the meeting. If you do not submit a proxy or voting instructions or do not vote in person at the meeting, or if you “ABSTAIN” from voting, the effect will be the same as a vote “AGAINST” the Merger.

Q: ARE THERE DIFFERENT VOTING PROCEDURES DEPENDING ON HOW I HOLD MY PROTONEX STOCK?

A: Yes. As summarized below, there are some distinctions between Protonex common stock held of record and those owned beneficially.

Holder of Record: If your shares of common stock are registered directly in your name with Protonex or its transfer agent, you are considered, with respect to those shares of common stock, the holder of record, and these proxy materials are being sent directly to you by Protonex. As the holder of record, you have the right to grant your voting proxy directly to Protonex or to vote in person at the special meeting. A proxy card is enclosed for you to use.

Beneficial Owner: If your shares of Protonex common stock are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of securities held in street name, and these proxy materials are being forwarded to you by your broker or nominee who is considered, with respect to those securities, the holder of record. As the beneficial owner, you have the right to direct your broker or nominee on how to vote and you are also invited to attend the special meeting. Your broker or nominee has enclosed a voting instruction card for you to use in directing the broker or nominee regarding how to vote your securities. The voting instruction card provides various alternative voting methods.

Table of Contents

Q HOW CAN I VOTE MY STOCK IN PERSON AT THE SPECIAL MEETING?

A: Shares of Protonex common stock held directly in your name as the holder of record may be voted in person at the special meeting. If you choose to do so, please bring the enclosed proxy card and proof of identification. Even if you plan to attend the special meeting, we recommend that you also submit your proxy as described below so that your vote will be counted if you later decide not to attend the special meeting. Securities held in street name may be voted in person by you only if you obtain a signed proxy from the record holder giving you the right to vote the securities in person.

Q: HOW CAN I VOTE MY PROTONEX STOCK WITHOUT ATTENDING THE SPECIAL MEETING?

A: Whether you hold securities directly as the holder of record or beneficially in street name, you may direct your vote without attending the special meeting. You may vote your directly held securities by granting a proxy or, for securities held in street name, by submitting voting instructions to your broker, bank, or nominee following the instructions on the form included with this proxy statement/prospectus by the deadline indicated on that form.

Q: HOW DO I VOTE?

A: If you are the stockholder of record (that is, the shares are held in your name), you may vote your proxy in one of two ways:

By mail: If you vote by traditional proxy card, mark your selections on the proxy card, date the card, and sign your name exactly as it appears on the card, then mail it in the postage-paid envelope enclosed with the materials. You should mail the proxy card sufficiently in advance to allow delivery prior to the special meeting.

In person: If you are a stockholder of record and attend the meeting, you may deliver your completed proxy card in person. If you are not the stockholder of record (that is, your shares are held in the name of a bank, broker, or other holder of record, which is often referred to as held in “street name”) then you will receive instructions from the holder of record that you must follow to ensure that your shares are voted as you wish. You will not be able to vote those shares at the meeting unless you have received, in advance, a proxy card from the record holder (that is, the bank, broker, or other holder of record).

If you complete and properly sign and timely return a proxy card to Protonex, your shares will be voted as you direct.

Q: MAY I CHANGE MY VOTE AFTER I HAVE GIVEN IT?

A: You may change your proxy instructions and your vote at any time prior to the vote at the special meeting. For shares held directly in your name, you may accomplish this by granting a new proxy bearing a later date, which automatically revokes the earlier proxy, and delivering such new proxy to Protonex’s corporate secretary either by mail or by attending the special meeting and voting in person. Attendance at the special meeting will not cause your previously granted proxy to be revoked unless you specifically request to do so. For securities held beneficially by you, you may accomplish this by submitting new voting instructions to your broker, bank, or nominee by the deadline indicated in the instructions sent to you by your broker, bank, or nominee.

Q: WHO BEARS THE COST OF SOLICITING PROXIES?

A: Protonex will pay the cost of distributing and soliciting proxies. This proxy solicitation is being made by Protonex on behalf of its board of directors. In addition to solicitation by use of the mail, Protonex’s and Ballard’s directors, officers and employees may also solicit proxies in person or by telephone, electronic mail, facsimile transmission or other means of communication. Protonex will also request brokers and other fiduciaries to forward proxy solicitation material to the beneficial owners of shares of Protonex common stock that the brokers and fiduciaries hold of record.

Protonex does not have a policy of paying regular dividends on its common stock and has never done so.

The Merger (page 40)

On June 29, 2015, Ballard entered into the Merger Agreement with Merger Sub, Protonex, and Edward J. Stewart, as the stockholder representative, pursuant to which Merger Sub will merge with and into Protonex 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 Ballard. The Merger is expected to close in the third calendar quarter of 2015.

Reasons for the Merger (page 42)

The Protonex board of directors unanimously adopted and approved the Merger Agreement. The Protonex board of directors also unanimously determined that the Merger Agreement is advisable and in the best interests of Protonex and its stockholders and unanimously recommended that Protonex’s stockholders adopt the Merger Agreement and approve the Merger and the other transactions contemplated thereby. In reaching its decision, the Protonex board of directors considered a number of factors that are described in more detail in “Background of the Merger” beginning on page 41. Individual members of the Protonex board of directors may have given different weight to different reasons.

Protonex stockholders should carefully read this proxy statement/prospectus in its entirety for more detailed information concerning the Merger. In addition, Protonex stockholders are directed to the Merger Agreement, which is included as Appendix A to this proxy statement/prospectus.

What Protonex Stockholders Will Receive in the Merger (page 44)

At the effective time of the Merger, on the terms and subject to the conditions set forth in the Merger Agreement, all of the equity securities of Protonex outstanding immediately prior to the effective time, other than equity securities held by stockholders that exercise appraisal rights under applicable law, will be converted into the right to receive a number of Ballard common shares, equal to U.S. $30,000,000 million less Protonex’s net debt and transaction expenses at the time of closing, divided by U.S. $2.28. Ballard expects to issue, pursuant to the Merger Agreement, up to 11,214,912 common shares (including approximately 628,732 shares to be deposited into escrow). On a per share basis, you will be entitled to receive approximately 0.1562 of a Ballard common share for each share of Protonex common stock you hold as of the effective time of the Merger.

The aggregate number Ballard common shares to be issued pursuant to the Merger Agreement will vary depending on a number of factors, including the amount of the estimated net debt of Protonex at closing. The Merger Agreement does not provide for an adjustment in the aggregate number of Ballard common shares to be issued by Ballard to Protonex’s stockholders in the Merger in the event of fluctuations in the market value of Ballard’s common shares up through the closing date. However, the number of shares to be issued by Ballard pursuant to the Merger Agreement is subject to adjustment based on Protonex’s net debt as of the closing date of the Merger. We currently estimate that, if the Merger closes on September 30, 2015, Ballard would issue 11,214,912 shares (including 628,732 shares to be deposited into escrow), which would represent approximately 7.3% of Ballard’s outstanding common shares as of the date of this proxy statement/prospectus (after giving effect to such issuance), assuming Protonex net debt and transaction expenses equal to U.S. $4,430,000. Protonex’s actual results of operations between the date of the financial information included in this proxy statement/prospectus and the closing date may differ from the forecasted results used in this estimate, resulting in differences between the forecast and actual amounts of Protonex’s net debt, including transaction expenses, as of the closing date of the Merger. See “Merger Agreement” located on page 56.

of this proxy statement/prospectus for further information and a discussion relating to the potential amount of shares to be issued by Ballard in the Merger.

In accordance with the Merger Agreement and Protonex’s 2003 Stock Incentive Plan and 2013 Stock Incentive Plan, holders of options to purchase Protonex common stock must exercise such options by the fifth business day prior to the special meeting of Protonex stockholders, or their options will be cancelled. In addition, under the Merger Agreement, Protonex has agreed to cause all outstanding warrants to purchase Protonex common stock to be exercised or terminated prior to the effective time of the Merger. Ballard will not assume any Protonex options, warrants or other derivative securities in connection with the Merger, and you will receive no Merger consideration in exchange for such securities. Any Protonex options or warrants duly exercised for shares of Protonex common stock prior to the effective time of the Merger will be entitled to the Merger consideration for their shares of common stock held at the effective time.

Principal Agreements

Merger Agreement (page 56)

The Merger Agreement, which was executed on June 29, 2015, sets forth the terms and conditions of the Merger, including terms for the conversion of securities in the Merger, escrow of certain Merger consideration, representations and warranties, indemnification, covenants of each party, closing conditions and termination provisions. See “Merger Agreement” on page 56 and Appendix A hereto for further information on the Merger Agreement.

Support Agreements (page 68)

Concurrently with the execution of the Merger Agreement, certain Protonex stockholders, who collectively hold approximately 56% of the outstanding shares of Protonex common stock as of the date of this proxy statement/prospectus, each have entered into support agreements with Ballard, pursuant to which these Protonex stockholders have agreed, among other things, to vote (or deliver written consents with respect to) all of the shares of Protonex capital stock held by such stockholders in favor of the approval of the Merger and the Merger Agreement and the other transactions contemplated thereby, to vote against any action that would reasonably likely result in a material breach of a representation, warranty, covenant or agreement of Protonex under the Merger Agreement, and to vote against any alternative transactions. Each support agreement also generally prohibits the Protonex stockholders signing it from transferring such stockholder’s shares of Protonex capital stock prior to the consummation of the Merger.

In addition, each of the Protonex stockholders that executed a support agreement has agreed that the Ballard common shares to be received by such stockholder in the Merger are subject to lock-up restrictions, which restrictions will lapse with respect to one-half of such Ballard common shares at the six and 12-month anniversaries of the closing date of the Merger. Such stockholder has agreed not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any Ballard common shares during the lock-up period.

Each support agreement will terminate upon the termination of the Merger Agreement in accordance with its terms. Collectively, the support agreements provide for the vote of a sufficient number of shares of Protonex to adopt the Merger Agreement and approve and the Mergers contemplated thereby under Delaware law and Protonex’s organizational documents.

Escrow Agreement (page 69)

Pursuant to an escrow agreement to be entered into between Ballard, Edward J. Stewart, as stockholder representative, and U.S. Bank, National Association, as escrow agent, Ballard will deposit approximately 628,732 common shares payable to the Supporting Stockholders, or 10% of the total Merger consideration to be paid to the Supporting Stockholders, into an escrow account maintained by U.S. Bank, National Association, as escrow agent. These common shares will be used to cover indemnification claims by Ballard pursuant to the terms of the Merger Agreement, which shares will be released 12 months after the closing of the Merger, subject to any then pending claims.

Risk Factors (page 21)

In deciding how to vote Protonex common stock on the matters described in this proxy statement/prospectus, you should carefully consider the risks related to the Merger, Ballard, Protonex and the combined company. The Merger may not achieve the expected benefits because of, among other things, the risks and uncertainties discussed in the sections entitled “Questions and Answers About the Special Meeting and the Merger”, “Risk Factors”, “Cautionary Statement Regarding Forward-Looking Statements” on pages 1, 21 and 32, respectively. Such risks include, among other things, risks relating to the uncertainty that Ballard and Protonex will be able to close the Merger or, if closed, integrate their businesses successfully, uncertainties as to whether the Merger will achieve expected synergies, and uncertainties relating to the performance of the combined company following the Merger.

Approval by Holders of Protonex Common Stock (page 35)

The adoption and approval of the Merger Agreement and the Merger requires the affirmative vote of the holders of a majority of the shares of Protonex common stock issued and outstanding on the record date and entitled to vote at the meeting. Collectively, the support agreements provide for the vote of a sufficient number of shares of Protonex to adopt and approve the Merger Agreement and the Merger under applicable Delaware law and Protonex’s organizational documents.

Conditions to the Merger (page 64)

Ballard and Protonex expect to complete the Merger after all of the conditions to the Merger in the Merger Agreement are satisfied or waived, including after the receipt of approval of the Merger at the special meeting of Protonex stockholders and the receipt of any required regulatory approvals. Ballard and Protonex currently expect to complete the Merger during the third calendar quarter of 2015. However, it is possible that factors outside of either Ballard’s or Protonex’s control could cause the Merger to be completed at a later time or not at all.

Each party’s obligation to complete the Merger is subject to the satisfaction or waiver (to the extent waiver is permitted under the Merger Agreement) of various conditions, including conditions relating to the following matters: (i) approval of the Merger by the Protonex stockholders, (ii) not more than 5% of the Protonex stockholders having exercised appraisal rights, (iii) the execution of certain ancillary agreements, (iv) all required consents and approvals necessary to consummate the Merger having been obtained, (v) the effectiveness of the registration statement on Form F-4 (of which this proxy statement/prospectus is a part) for purposes of registering the shares, (vi) no injunction or proceeding by a government entity seeking to restrain or prohibit consummation of the Merger, (vi) no material adverse changes of Protonex, (vii) the other party’s compliance with its covenants and agreements contained in the Merger Agreement (subject to customary materiality qualifiers), (viii) each party’s receipt of an opinion from outside legal counsel that is reasonably acceptable and dated as of the closing date of the Merger to the effect that, on the basis of the facts, representations and assumptions set forth or referred to in such opinion, the Merger will qualify for U.S. federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code; provided, however, that if Protonex’s counsel is unable, unwilling or otherwise fails to deliver such opinion, then Ballard’s counsel may deliver such opinion to Protonex; (ix) the approval for listing of such shares on the TSX and the NASDAQ; (x) subject to certain limitations and exceptions, the accuracy of the other party’s representations and warranties; (xi) evidence of the adoption and approval by Ballard, as the sole stockholder of Merger Sub of the Merger Agreement, the Merger and the other transactions contemplated hereby; (xii) executed resolutions of Protonex’s board of directors authorizing the termination of all of Protonex’s unexercised stock options; (xiii) the execution of employment agreements by certain key employees of Protonex; and (xiv) if a 280G Vote (as defined in the Merger Agreement) is required (1) Protonex shall have received and delivered to Ballard a parachute payment waiver from each person that is eligible to receive a “parachute payment” and (2) Protonex’s stockholders shall have (A) approved any such “parachute payments” or (B) shall have voted upon and disapproved such “parachute payments,” and, as a consequence, such “parachute payments” shall not be paid.

Termination of the Merger Agreement (page 67)

The Merger Agreement contains certain provisions giving Ballard and Protonex the right to terminate the Merger Agreement under certain circumstances. The Merger Agreement may be terminated at any time before the effective time of the Merger:

· by mutual written consent of Ballard and Protonex;

13

Table of Contents

· by either party if the closing does not occur by December 31, 2015, with certain conditions;

· by Ballard if there is: a material breach of any representation or warranty of Protonex in the Merger Agreement or in the support agreement or any covenant or agreement to be complied with or performed by Protonex, the failure of certain conditions on or prior to December 31, 2015, or the occurrence of any event which results or would result in the failure of a condition to Ballard’s obligations to effect the Merger to be satisfied on or prior to December 31, 2015 or Protonex failed to obtain the stockholder approval of the Merger;

· by Protonex if there is a material breach of any representation or warranty of Ballard or Merger Sub in the Merger Agreement or of any covenant or agreement to be complied with or performed by Ballard or Merger Sub, the failure of certain conditions on or prior to December 31 2015, or the occurrence of any event which results or would result in the failure of a condition to Protonex’s obligations to effect the Merger to be satisfied on or prior to December 31, 2015; or

· by Protonex, if at any time prior to obtaining the approval of the Protonex stockholders, the Company has received an acquisition proposal that the Protonex board of directors has determined to be a superior proposal (as defined in the Merger Agreement).

Termination Fees and Expenses (page 67)

If the Merger Agreement is terminated by Protonex pursuant to the fourth bullet in the section entitled “Merger Agreement—Termination of the Merger Agreement” above, then Ballard is required to pay Protonex a termination fee of $200,000, unless, as a result of willful and intentional breach by Ballard or Merger Sub, Protonex notifies Ballard in writing at the time of termination that it will pursue a remedy other than the termination amount.

If the Merger Agreement is terminated by Ballard pursuant to the either the second or third last bullet in the section entitled “Merger Agreement—Termination of the Merger Agreement” above, then Protonex is required to pay Ballard a termination fee of $200,000.

If the Merger Agreement is terminated by Protonex pursuant to the last bullet in the section entitled “Merger Agreement—Termination of the Merger Agreement” above, then Protonex is required to pay Ballard a termination fee of $1,500,000, plus Ballard’s fees and expenses.

Resale of Ballard Common Shares (page 44)

All Ballard common shares that each Protonex stockholder receives in the Merger will be listed on the TSX and the NASDAQ and will be freely transferable under Canadian and U.S. securities laws unless a stockholder is deemed an affiliate of Protonex immediately prior to the Merger or an affiliate of Ballard following the Merger for purposes of the U.S. securities laws or a control person of Ballard following the Merger for purposes of Canadian securities laws.

Furthermore, all of the Protonex stockholders that executed the support agreements (as described in “Ancillary Agreements—Support Agreement”) agreed that the Ballard common shares to be received by Protonex stockholders in the Merger are all subject to lock-up restrictions, which restrictions will lapse with respect to one-half of such Ballard common shares at the six and 12-month anniversaries of the closing date of the Merger.

Interests of Certain Persons in the Merger (page 43)

Certain directors and executive officers of Protonex have interests in the Merger that may be in addition to or different from those of other Protonex stockholders, including:

· change of control bonus payments to be made to certain executive officers of Protonex;

· the acceleration of vesting of certain options held by certain directors and executive officers of Protonex; and

· the continued indemnification and directors’ and officers’ insurance coverage of current Protonex directors and officers following the Merger.

Material U.S. Federal Income Tax Consequences (page 45)

The Merger is intended to qualify as a reorganization within the meaning of Section 368(a) of the Code. It is a condition to the closing of the Merger that each party shall have received an opinion from outside legal counsel to the effect that the Merger should qualify as such a reorganization. Assuming the Merger qualifies as a reorganization for U.S. federal income tax purposes, U.S. holders (as defined below under “The Merger Proposal—Material U.S. Federal Income Tax Consequences”) of Protonex common stock will not recognize income, gain or loss on the exchange of their Protonex common stock for Ballard common shares in the Merger (other than a U.S. holder of Protonex common stock who is a “five-percent transferee shareholder” within the meaning of the rules under Treasury regulations Section 1.367(a)-3(c) and who does not file a gain recognition agreement with the IRS).

The discussion of U.S. federal income tax considerations set forth herein is for general information only and does not purport to be a complete analysis or listing of all potential tax effects that may apply to a U.S. holder of Protonex common stock. Protonex Stockholders should consult their own tax advisors to determine the particular tax consequences to them of the Merger, including the application and effect of U.S. federal, state, local, foreign and other tax laws.

The foregoing summary of U.S. federal income tax consequences of the Merger is qualified in its entirety by the longer form discussion under “The Merger Proposal—Material U.S. Federal Income Tax Consequences” beginning on page 45. Neither Protonex nor Ballard has sought or obtained a ruling from the IRS regarding any of the tax consequences of the Merger. Accordingly, there can be no assurance that the IRS will not challenge this tax treatment of the Merger or that the U.S. courts will uphold this tax treatment in the event of an IRS challenge.

Material Canadian Federal Income Tax Consequences (page 50)

A holder who acquires Ballard common shares as beneficial owner in connection with the Merger and who, at all relevant times, for the purposes of the Income Tax Act (Canada) (the “Tax Act”), (i) holds such common shares as capital property, deals at arm’s length with Ballard, and is not affiliated with Ballard and (ii) is not, and is not deemed to be, resident in Canada and does not use or hold the Ballard common shares in connection with carrying on a business in Canada will not be subject to tax under the Tax Act in respect of any capital gain realized by such holder on a disposition of the common shares, unless such shares constitute “taxable Canadian property” (as defined in the Tax Act) of such holder at the time of disposition and such holder is not entitled to relief under an applicable income tax treaty or convention.

Board (“IFRS”). From the date of completion of the Merger, our results of operations will include Protonex’s operating results and assets and liabilities.

Regulatory Matters (page 54)

Protonex and Ballard intend to make all required filings under the Securities Act and the Exchange Act in connection with the Merger. In addition to the SEC filings there are filings required with the TSX and the NASDAQ relating to the listing of the Ballard common shares to be issued in the Merger. Further, Protonex and Ballard have filed a notification with the Directorate of Defense Trade Controls of the U.S. State Department pursuant to Section 122.4 of the International Traffic in Arms Regulations.

The Merger is not subject to pre-merger notification under any U.S. or foreign antitrust laws, but it may be reviewed by the Antitrust Division and the Federal Trade Commission and by foreign antitrust authorities, under U.S. or foreign antitrust laws, respectively. The Merger may also be reviewed by the SEC under the Securities Act and Exchange Act, and by foreign governmental authorities, including Canadian securities regulatory authorities and the TSX.

Appraisal Rights (page 52)

Under Delaware law, stockholders of Protonex can exercise appraisal rights in connection with the Merger. A stockholder that does not vote in favor of the Merger proposal and complies with all of the other necessary procedural requirements will have the right to dissent from the Merger and to seek appraisal of the fair value of their Protonex common stock, exclusive of any element of value arising from the expectation or accomplishment of the Merger.

Comparison of Rights of Stockholders of Ballard and Protonex (page 96)

Protonex is incorporated in the State of Delaware and the rights of Protonex stockholders are currently governed by the Delaware General Corporation Law (the “DGCL”) and Protonex’s certificate of incorporation and by-laws. After the completion of the Merger, stockholders of Protonex who receive Ballard’s common shares in the Merger will become stockholders of Ballard and will become subject to Ballard’s articles and the applicable provisions of the CBCA.

Enforceability of Civil Liabilities against Foreign Persons

Ballard is a corporation governed by the CBCA. The majority of Ballard’s assets are located outside the United States and certain of Ballard’s directors and officers and some of the experts named in this proxy statement/prospectus reside outside the United States. Because some of these persons are located outside the United States, it may not be possible for you to effect service of process within the United States on these persons. Furthermore, it may not be possible for you to enforce against Ballard or them, in the United States, judgments obtained in United States courts, because some of Ballard’s assets and the assets of these persons are located outside the United States.

There is doubt as to the enforceability, in original actions in Canadian courts, of liabilities based on the United States federal securities laws or “blue sky” laws of any state within the United States and as to the enforceability in Canadian courts of judgments of U.S. courts obtained in actions based on the civil liability provisions of the United States federal securities laws or any such state securities or blue sky laws. Therefore, it may not be possible to enforce those judgments against Ballard, its directors and officers and some of the experts named in this proxy statement/prospectus, including the appendices hereto.

Selected Unaudited Pro Forma Condensed Financial Data

The unaudited pro forma condensed consolidated financial statements of Ballard for the six months ended June 30, 2015 and the year ended December 31, 2014 included in this proxy statement/prospectus have been prepared by Ballard using the business combination rules under IFRS. The unaudited pro forma condensed consolidated statement of financial position of Ballard as at June 30, 2015 assumes that the Merger took place on June 30, 2015, and combines Ballard’s unaudited condensed consolidated statement of financial position at June 30, 2015

with Protonex unaudited consolidated balance sheet at March 31, 2015, with adjustments. The unaudited pro forma condensed consolidated statement of profit or loss and other comprehensive income (loss) of Ballard for the six months ended June 30, 2015 assumes that the Merger took place as of January 1, 2014 and combines the unaudited condensed consolidated statement of profit or loss and other comprehensive income (loss) of Ballard for the six months ended June 30, 2015 and the unaudited consolidated statement of comprehensive income (loss) of Protonex for the six months ended March 31, 2015, with adjustments. The unaudited pro forma condensed consolidated statement of profit or loss and other comprehensive income (loss) of Ballard for the year ended December 31, 2014 assumes that the Merger took place as of January 1, 2014 and combines the audited consolidated statement of profit or loss and other comprehensive income (loss) of Ballard for the year ended December 31, 2014 and the audited consolidated statement of income (loss) of Protonex for the year ended September 30, 2014, with adjustments. In preparing these unaudited pro forma condensed financial statements, Ballard has adjusted Protonex’s financial statements to conform to IFRS and to Ballard’s accounting policies. These adjustments are described in the notes to the unaudited pro forma condensed financial statements of Ballard for the six months ended June 30, 2015 and the year ended December 31, 2014 which should be read in conjunction with the selected unaudited pro forma condensed financial data presented below.

The unaudited pro forma condensed financial statements assume that, at the effective time of the Merger, each outstanding share of Protonex common stock will be converted into the right to receive approximately 0.1562 of a Ballard common share. Pro forma book value per share is calculated by dividing total assets (including both tangible and intangible assets) minus total liabilities of Ballard as at June 30, 2015 under IFRS by the total number of Ballard common shares outstanding at such date (including issuance of Ballard shares to Protonex stockholders as of such date).

The selected unaudited pro forma condensed financial data is based on estimates and assumptions that are preliminary, presented for illustrative purposes only and is not necessarily indicative of the combined financial position or results of operations of future periods or the results that actually would have been realized had the entities been a single entity during these periods. The assumptions underlying the selected unaudited pro forma condensed financial data described in the notes to the unaudited pro forma condensed financial statements of Ballard for the six months ended June 30, 2015 and should be read in conjunction with the selected unaudited pro forma condensed financial data presented below.

On June 29, 2015, the date of execution and announcement of the Merger Agreement, the closing share price of a Ballard common share on the NASDAQ and the TSX was U.S. $2.14 and C$2.63, respectively.

The market price of Ballard’s common shares could change significantly. Because the equity consideration to be paid in the Merger will not be adjusted for changes in the market price of Ballard’s common shares through the closing date of the Merger, the value of the consideration that holders of shares of Protonex common stock will receive in the Merger may vary significantly from the market value of Ballard’s common shares that holders of shares of Protonex common stock would have received if the Merger was completed on the date the Merger Agreement was executed and announced, or on the date of the special meeting of Protonex stockholders on this proxy statement/prospectus.

Dividend Policies

Ballard has not paid any dividends to date on its common shares. Ballard intends to retain its earnings, if any, to finance the growth and development of its business. Accordingly, it does not currently expect to pay any dividends on its common shares in the near future.

Following completion of the Merger, the holders of Ballard’s common shares will be entitled to receive any dividends as may be declared by the Ballard board of directors from funds legally available therefor. The dividend policy of the combined company will be determined by its board of directors.

Protonex

Historical market price information regarding Protonex capital stock is not provided because there is currently no public trading market for Protonex’s common stock. As of August 11, 2015, the record date for the special meeting, there were 64,978,500 shares of Protonex common stock outstanding, held by 148 holders of record. No shares of Protonex preferred stock were issued and outstanding as of such date. Protonex does not have a policy of paying regular dividends on its common stock and has never done so.

RISK FACTORS

Protonex’s stockholders should carefully consider the following factors in connection with their vote to adopt the Merger Agreement and their potential receipt of Ballard’s common shares in the Merger. These factors should be considered in conjunction with the other information included, or incorporated by reference in, this proxy statement/prospectus. Additional risks and uncertainties not presently known to Protonex or Ballard, or that are not currently believed to be important to you, also may adversely affect the combined company and its stockholders following the Merger.

Risks Relat e d to the Merger

Even if the Merger is completed, we may not be able to fully realize all of the projected synergies and anticipated benefits of the Merger.

The success of the Merger will depend on, among other things, the ability to realize anticipated revenue and cost savings, enhance the combined company’s global reach and to combine Ballard’s business with Protonex in a manner that potentially creates opportunities through strategic relationships, that does not materially disrupt existing relationships or otherwise result in decreased productivity and that allows Ballard to capitalize on the capabilities of the combined company. If these objectives are not achieved, the anticipated benefits of the Merger may not be realized fully or at all or may take longer to realize than expected.

The combined company may not realize projected revenue gains, cost savings and synergies in connection with the Merger on the timetable contemplated, if at all. In addition, the actual integration may result in additional and unforeseen expenses, and the anticipated benefits of the integration plan may not be realized. Actual revenue and cost synergies, if achieved at all, may not be achieved at the levels expected and may take longer than anticipated. If these challenges are not adequately addressed, Ballard and Protonex may be unable to realize the anticipated benefits of the integration of the two companies. An inability to realize the full extent of, or any of, the anticipated benefits of the Merger, as well as any delays encountered in the integration process, could have a material adverse effect on the combined company’s business and results of operations, which may affect the value of the combined company’s common shares.

We may not realize the operating and financial benefits we expect from the Merger.

The post-acquisition integration of Ballard and Protonex may be complex, time-consuming and expensive, and may disrupt the day-to-day management and operation of our respective businesses. Both Ballard and Protonex have operated and, until the completion of the Merger, will continue to operate independently. It is possible that the integration process could result in the disruption of Ballard’s or Protonex’s ongoing businesses or inconsistencies in standards, controls, procedures or policies that could adversely affect the ability of the combined company to maintain relationships with third parties and employees or to achieve the anticipated benefits of the Merger. After the Merger, the combined company may need to overcome significant challenges in order to realize any benefits or synergies from the Merger. These challenges include the timely, efficient, and successful completion of a number of post-acquisition events, including the following:

· integrating the operations and technologies of the companies;

· implementing disclosure controls, internal controls and financial reporting systems to comply with applicable securities laws and stock exchange rules;

· retaining and assimilating the key personnel of each company;

· resolving possible inconsistencies in operating and product standards, internal controls, procedures and policies, business cultures, corporate governance and reporting practices and compensation methodologies between the companies;

· retaining existing vendors and customers of the companies and attracting additional customers;

· retaining strategic partners of each company and attracting new strategic partners; and

21

Table of Contents

· creating uniform business standards, procedures, policies, and information systems.

The execution of these post-acquisition integration events involve considerable risks and may not be successfully implemented, or if implemented, on a timely basis. These risks include the following:

· potential disruption of ongoing business operations and distraction of the management of the combined company;

· potential strain on financial and managerial controls and reporting systems and procedures of the combined company;

· unanticipated expenses and potential delays related to integration of the operations, technology, and other resources of the companies;

· potential impairment of relationships with employees, suppliers, and customers as a result of the inclusion and integration of management personnel; and

· potential unknown liabilities associated with the Merger and the combined operations.

The combined company may not succeed in mitigating these risks or any other problems encountered in connection with the Merger.

Failure to complete, or a delay in completing, the Merger could adversely affect Ballard’s and Protonex’s future business and operations.

The Merger is subject to the satisfaction, or, in certain circumstances, waiver, of various closing conditions, including obtaining the approval by Protonex’s stockholders and certain other conditions described in the Merger Agreement that are outside the control of Ballard and Protonex that may prevent, delay or otherwise materially adversely affect its completion. Ballard’s and Protonex’s respective obligations to complete the Merger are also subject to the other conditions listed under “Merger Agreement—Conditions to Consummation of the Merger” on page 67. Neither Ballard nor Protonex can assure you whether or when these conditions will be satisfied or waived, or whether the Merger will be successfully completed. Any delay in completing the Merger could cause the combined company not to realize some or all of the synergies and other benefits that Ballard and Protonex expect to achieve if the Merger is successfully completed within its expected time frame.

In the event that the Merger is not completed:

· Ballard and Protonex would not realize any potential benefits of the Merger, including anticipated revenue and cost synergies;

· Ballard’s and Protonex’s management’s attention from day-to-day business may be diverted, Ballard and Protonex may lose key employees, and Ballard’s and Protonex’s relationships with their respective customers and partners may be disrupted as a result of uncertainties with regard to each company’s business and prospects;

· the business relationship between Ballard and Protonex may be adversely impacted;

· under certain circumstances, Ballard or Protonex may be required to pay the other party a termination fee of U.S. $200,000; provided that if Protonex terminates the Merger Agreement to pursue a superior proposal, then Protonex will be required to pay Ballard U.S. $1,500,000 plus Ballard’s expenses; and

· Ballard and Protonex will each incur and must pay significant costs and expenses related to the Merger, such as legal, accounting and advisory fees.

Any such events could adversely affect Ballard’s and Protonex’s business and operating results.

22

Table of Contents

Ballard’s and Protonex’s business could suffer due to the announcement, pendency and consummation of the Merger.

The announcement, pendency and consummation of the Merger may have a negative impact on Ballard’s, Protonex’s, and the combined company’s ability to sell their respective products and services, attract and retain key management, technical, sales, or other personnel, maintain and attract new customers, and maintain strategic relationships with third parties. For example, Ballard and Protonex, and following consummation of the Merger, the combined company, may experience the deferral, cancellation or a decline in the size or rate of orders for its products or services or a deterioration in customer relationships. If this were to occur, Ballard’s and Protonex’s revenues, and the revenues of the combined company, could decline materially or any anticipated increases in revenue due to potential synergies or otherwise could be lower than expected. Also, speculation regarding the likelihood of the closing of the Merger could increase the volatility of Ballard’s common share price. Any such events could harm Ballard’s and Protonex’s, and following the Merger the combined company’s, operating results and financial condition.

The price of Ballard’s common shares may fluctuate, and the purchase price payable in the Merger will not be adjusted for any changes in the price of Ballard’s common shares.

The consideration payable in connection with the Merger will be paid through the issuance to the stockholders of Protonex of approximately 11,214,912 of Ballard’s common shares (or approximately 0.1562 Ballard common shares for each share of Protonex common stock owned, based upon 71,803,021 fully diluted shares of Protonex common stock expected to be outstanding as of the date of the special meeting of Protonex stockholders). Under the Merger Agreement, other than as a result of reclassifications, stock splits, stock dividends and similar changes effected by Ballard, the number of Ballard’s common shares to be issued will not be adjusted even if the market price of Ballard’s common shares fluctuates between the date of the Merger Agreement and the closing date of the Merger. The market price of Ballard’s common shares at the closing of the Merger will likely vary from the market price at the date of this proxy statement/prospectus and at the date of the Protonex special meeting of stockholders. Stock price changes may result from a variety of factors that are beyond the control of Ballard or Protonex, including:

· market reaction to the announcement and pendency of the Merger and market assessment of the merits and risks of the Merger and the likelihood of the Merger being consummated;

· changes in the respective businesses, operations, or prospects of Ballard’s or Protonex’s business;

· governmental or litigation developments or regulatory considerations affecting the fuel cell industry or other aspects of Ballard’s or Protonex’s businesses;

· general business, market, industry or economic conditions; and

· other factors beyond the control of Ballard or Protonex, including those described elsewhere in this “Risk Factors” section or in the documents incorporated by reference herein.

Neither party is permitted to “walk away” from the Merger or re-solicit the vote of its stockholders solely because of changes in the market price, and, therefore, the value, of Ballard’s common shares through the closing date of the Merger. Any reduction in Ballard’s stock price would result in Protonex stockholders receiving less value in the Merger. Conversely, any increase in Ballard’s stock price would potentially result in Protonex stockholders receiving greater value in the Merger. The specific dollar value per share of Ballard’s common shares that Protonex’s stockholders would receive upon completion of the Merger will depend on, among other things, the market value of Ballard’s common shares at that time, the number of shares of Protonex common stock then issued and outstanding and other factors discussed in this proxy statement/prospectus. Protonex’s stockholders will not know the exact value of Ballard’s common shares to be issued in the Merger at the time of the Protonex special meeting of stockholders.

If the Merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, the stockholders of Protonex may be required to pay substantial U.S. federal income taxes.

It is a condition to the completion of the Merger that Protonex and Ballard each receive an opinion from outside legal counsel that, for U.S. federal income tax purposes, the Merger should qualify as a reorganization within the meaning of Section 368(a) of the Code. The opinions of outside legal counsel will be based on certain assumptions, representations and covenants made by Ballard and Protonex. If any of those representations, covenants and assumptions is inaccurate, the conclusions reached by counsel in such opinions may not apply. Moreover, the opinions of outside tax counsel do not bind the IRS nor do they prevent the IRS from adopting a contrary position. Neither Ballard nor Protonex has requested, or intends to request, a ruling from the IRS, with respect to the tax consequences of the Merger, and there can be no assurance that the companies’ position would be sustained by a court if challenged by the IRS. If the Merger does not qualify as a reorganization within the meaning of Section 368(a) of the Code, Protonex stockholders will recognize gain or loss upon their receipt of Ballard common shares in connection with the Merger. For a more complete discussion of the tax consequences of the Merger, see the section entitled “The Merger Proposal—Material U.S. Federal Income Tax Consequences of the Merger” beginning on page 46.

The Merger is expected to result in an ownership change for Protonex and may result in an ownership change for Ballard under Section 382 of the Code, substantially limiting the use of the net operating loss, referred to as “NOL,” carryforwards and other tax attributes of Protonex and possibly of Ballard’s U.S. subsidiaries to offset future taxable income of the combined company.

In general, under Section 382 of the Code, a corporation that undergoes an “ownership change” within the meaning of Section 382 of the Code is subject to limitations on the utilization of net operating loss carryforwards, which we refer to as NOL carryforwards, generated prior to such ownership change to offset future taxable income. In general, an ownership change occurs if the aggregate stock ownership of certain stockholders increases by more than 50 percentage points over such stockholders’ lowest percentage ownership during the testing period (which is generally three years). If an ownership change occurs, Section 382 imposes an annual limitation on the amount of income against which pre-ownership change NOL carryforwards may be offset. The annual limitation is generally equal to the value of the stock of the corporation immediately prior to the ownership change, multiplied by the adjusted federal tax-exempt rate set by the IRS.

The Merger is expected to result in an ownership change for Protonex and may result in an ownership change for Ballard under Section 382 of the Code, potentially limiting the use of the NOL carryforwards of Protonex and Ballard’s U.S. subsidiaries to offset future taxable income of the combined company for both federal and state income tax purposes. Whether the Merger results in an ownership change for Ballard and its U.S. subsidiaries depends on other past and future changes in stock ownership. Moreover, the utilization of the combined company’s NOL carryforwards depends on the timing and amount of taxable income earned in the future, which neither Protonex nor Ballard is able to predict. These tax attributes are subject to expiration at various times in the future to the extent that they have not been applied to offset the taxable income of the combined company. These limitations may affect the timing of when these NOL carryforwards can be used which, in turn, may impact the timing of when cash is used to pay the taxes of the combined company and could limit the benefits of NOL carryforwards for the business, financial condition or results of operations of the combined company.

The Merger could cause Ballard or Protonex to lose key personnel, which could materially adversely affect the combined company’s business and require the combined company to incur substantial costs to recruit replacements for lost personnel.

As a result of the Merger, Ballard’s current and prospective employees and Protonex’s employees could experience uncertainty about their future roles within the combined company. This uncertainty may adversely affect their ability or willingness to continue with the combined company, and the ability of the combined company to attract and retain key management, sales, marketing, and technical personnel. Any failure to retain and attract key personnel could have a material adverse effect on Ballard’s and Protonex’s current businesses and the business of the combined company after the completion of the Merger.

Some of Protonex’s officers and directors have conflicts of interest that may influence them to support or approve the issuance of Ballard common shares in connection with the Merger.

Certain officers and directors of Protonex participate in arrangements that provide them with material interests in the Merger that are different from and in addition to those of Protonex’s stockholders, including, among others, the payment of certain change-of-control bonuses to executive officers and the acceleration of vesting of certain options

24

Table of Contents

held by executive officers and directors of Protonex upon a change of control, as well as certain indemnification arrangements for Protonex’s directors and officers. These interests, among others, may influence Protonex’s directors and officers to support or approve the Merger. For a more detailed discussion, see the section entitled “The Merger Proposal — Interests of Certain Protonex Directors, Officers, and Affiliates in the Merger” on page 43.

Ballard expects to incur significant costs as a result of the integration of its operations with Protonex.

There are inconsistencies in standards, controls, accounting principles, procedures and policies, business cultures, and compensation structures between Ballard and Protonex. The integration of Ballard’s operations and the operations of Protonex and reconciling the inconsistencies in the standards, controls, accounting principles, procedures and policies, business cultures, and compensation structures between Ballard and Protonex may result in additional costs for the combined company. There are no assurances that such inconsistencies can be reconciled seamlessly or at all. The failure to reconcile such inconsistencies may lessen the anticipated benefits of the Merger.

We incur a variety of costs as a result of being a public company, and those costs may increase as a result of the Merger.

As a Canadian public company and a foreign private issuer registered with the SEC under the Exchange Act, we incur significant legal, accounting, and other expenses. In addition, the Sarbanes-Oxley Act of 2002, as well as rules implemented by the SEC and the NASDAQ Stock Market, frequently require changes in corporate governance policies and practices of public companies. These rules and regulations increase legal and financial compliance costs and make some activities more time-consuming and costly. In addition, we incur additional costs associated with our Canadian and Exchange Act public company reporting requirements. As a result, implementation of disclosure controls, internal controls, and financial reporting systems complying with the requirements of Canadian and U.S. securities laws and accounting and auditing standards required as a result of our continued status as a reporting company following effectiveness of the Merger may be more difficult and costly than anticipated.

Protonex stockholders will own a smaller percentage of Ballard than they currently own in Protonex.

After completion of the Merger, Protonex stockholders will own a smaller percentage of Ballard than they currently own in Protonex. Protonex stockholders, in the aggregate, will own approximately 7.3% of Ballard’s outstanding common shares immediately after completion of the Merger (such ownership percentages are based on the number of Protonex and Ballard shares outstanding as of August 11, 2015, and will vary based upon the actual number of Ballard and Protonex shares outstanding as of the effective time of the Merger). Because of this, Protonex stockholders will have less influence over the management and policies of Ballard than they now have over the management and policies of Protonex.

You may have difficulty bringing suit and enforcing judgments against Ballard.

Because Ballard is organized under the laws of Canada and many of its directors and officers are residents of countries other than the United States, it may be more difficult for U.S. investors to effect service of process or to realize in the United States upon judgments of U.S. courts predicated upon civil liabilities under the Exchange Act. Furthermore, it may be difficult for investors to enforce judgments of U.S. courts based on civil liability provisions of the U.S. federal securities laws or state securities or “blue sky” laws in a foreign court against Ballard or any of its non-U.S. resident officers or directors, or against non-U.S. resident persons named as experts in this proxy statement/prospectus.

After the Protonex stockholders have approved the Merger Agreement, Protonex may not terminate the Merger Agreement for any reason, such as a third-party’s proposal to acquire Protonex.

After the Protonex stockholders approve the Merger Agreement, Protonex’s options are limited. For example, it may not participate in discussions or negotiations with a person making a competing proposal and may not terminate the Merger Agreement in order to accept another proposal to acquire Protonex.

The common shares to be received by Protonex stockholders as a result of the Merger will have different rights from the shares Protonex common stock.

Upon consummation of the Merger, Protonex stockholders, other than those who properly exercise and perfect appraisal rights, will become Ballard stockholders, and their rights as stockholders will be governed by Ballard’s articles and by-laws as well as the CBCA. Certain of the rights associated with Ballard’s common shares are different from, and may be viewed as less favorable than, the rights associated with Protonex’s outstanding common stock. See “Comparison of Rights of Stockholders of Ballard and Protonex” beginning on page 96 of this proxy statement/ prospectus for a discussion of certain different rights associated with Ballard’s common shares.

The unaudited pro forma condensed combined financial statements included in this proxy statement/prospectus are preliminary and the actual financial condition and results of operations after the Merger may differ materially.

The future results of the combined company may be materially different from those shown in the unaudited pro forma condensed combined financial statements presented in this proxy statement/prospectus, which show only a combination of the historical results of Ballard and Protonex. Ballard expects to incur significant costs associated with the completion of the Merger and combining the operations of the two companies, the exact magnitude of which is not yet known. In addition, these costs may decrease the capital that the combined company could use for revenue-generating investments in the future. Furthermore, potential growth, expected financial results, perceived synergies and anticipated opportunities may not be realized through the completion of the Merger.

Risks Related to Ballard’s Business

For additional risks related to Ballard’s business (and the business of the combined company after the Merger), see the section entitled “Risk Factors” in Ballard’s Annual Information Form dated February 26, 2015, attached as an exhibit to its Annual Report on Form 40-F for the year ended December 31, 2014 and incorporated by reference herein.

Risks Related to Protonex’s Business

The current market for off-grid and mobile industry systems is dependent on macroeconomic factors

The developing market for off-grid and remote industry systems is expected to continue to grow because of its increasing strategic importance. However, many of our customers and potential customers are dependent on the overall economy, government budgets and state and federal economic programs. Significant changes in these factors can have a positive or negative effect on the market for off-grid and remote power systems products.

Defense spending volatility could have an adverse impact on the business of Protonex

On the whole defense spending in the USA has been volatile but with potential upsides in the areas of innovation, modernization and increased efficiency. Sequestration could have negative consequences for Protonex, both with respect to timing and volume of development programs with defense partners and with respect to product orders.

Defense acquisition process changes could have an adverse impact on the business of Protonex

The United States Department of Defense at times modifies its procurement processes, cycles, and regulations. Protonex has been successful in understanding the very complex world of government procurement, but there can be no assurance that the government will not change its processes, regulations, and policies in a manner that will adversely affect Protonex’s ability to sell products and services to the Department of Defense, which in turn would harm Protonex’s business operations.

If Protonex does not respond effectively and on a timely basis to rapid technological change, Protonex’s business could suffer.

The markets in which Protonex operates are characterized by changing technology and evolving industry standards. There can be no assurance that Protonex’s current and future competitors will not be able to develop products or expertise comparable or superior to those Protonex has developed or to adapt more quickly than Protonex to new technologies, evolving industry standards or customer requirements. Failure or delays in Protonex’s ability to develop products to respond to industry or user trends or developments and the actions of Protonex’s competitors

26

Table of Contents

could have a material adverse effect on Protonex’s business, results of operations and financial condition. Protonex’s ability to anticipate changes in technology, technical standards and product offerings will be a significant factor in the success of Protonex’s current business and expansion into new markets.

Protonex’s business could suffer if it does not adequately protect its intellectual property rights

As the intellectual property incorporated into its products become more complex, there remains a certain risk of possible patent infringement by Protonex. However, as a result of its unique position as a supplier of fuel cell and power manager systems, Protonex has filed applications for or obtained intellectual property rights (currently 94 patents granted or pending), which puts Protonex in a strong position relative to Protonex’s competitors. However, is it entirely possible that Protonex may incur legal expenses to defend these patents. Due to Protonex’s orientation as a provider of energy supply solutions, there is a risk that integration solutions are covered by intellectual property rights that have already been granted to others. Protonex works continuously with experienced patent attorneys to ensure that it is operating in full compliance with the law by staying abreast of patents that may be relevant to Protonex.

Protonex may not be able to enforce or protect Protonex’s intellectual property rights, which may harm Protonex’s ability to compete and harm Protonex’s business.

Protonex’s future success will depend, in part, on Protonex’s ability to protect Protonex’s proprietary methodologies and other valuable intellectual property.

Protonex’s ability to enforce Protonex’s intellectual property rights is subject to general litigation risks, as well as uncertainty as to the enforceability of Protonex’s intellectual property rights in various countries. To the extent that Protonex seeks to enforce Protonex’s rights, Protonex could be subject to claims that an intellectual property right is invalid, otherwise not enforceable, or is licensed to the party against whom Protonex is pursuing a claim. In addition, Protonex’s assertion of intellectual property rights may result in the other party seeking to assert alleged intellectual property rights or assert other claims against Protonex, which could harm Protonex’s business. If Protonex is not successful in defending such claims in litigation, Protonex may not be able to sell or license a particular service or product due to an injunction, or Protonex may have to pay damages that could, in turn, harm Protonex’s results of operations. Protonex has granted the U.S. government rights to some intellectual property in conjunction with government funded research and development, and the government may assert those rights. In addition, governments may adopt regulations, or courts may render decisions, requiring compulsory licensing of intellectual property to others, or governments may require that products meet specified standards that serve to favor local companies. Protonex’s inability to enforce Protonex’s intellectual property rights under these circumstances may harm Protonex’s competitive position and Protonex’s business.

Protonex’s services or solutions could infringe upon the intellectual property rights of others and Protonex may be subject to claims of infringement of third-party intellectual property rights.

Protonex cannot be sure that Protonex’s products do not infringe on the intellectual property rights of others. Third parties may assert against Protonex or Protonex’s customers claims alleging infringement of patent, copyright, trademark, or other intellectual property rights to technologies or services that are important to Protonex’s business. Infringement claims could harm Protonex’s reputation, cost Protonex money and prevent Protonex from offering some products or solutions. In Protonex’s contracts, Protonex generally agrees to indemnify Protonex’s clients for certain expenses or liabilities resulting from potential infringement of the intellectual property rights of third parties. In some instances, the amount of Protonex’s liability under these indemnities could be substantial. Any claims that Protonex’s products, services or processes infringe the intellectual property rights of others, regardless of the merit or resolution of such claims, may result in significant costs in defending and resolving such claims, and may divert the efforts and attention of Protonex’s management and technical personnel from Protonex’s business. In addition, as a result of such intellectual property infringement claims, Protonex could be required or otherwise decide that it is appropriate to:

· pay third-party infringement claims;

· discontinue using, licensing, or selling particular products subject to infringement claims;

· discontinue using the technology or processes subject to infringement claims;

27

Table of Contents

· develop other technology not subject to infringement claims, which could be costly or may not be possible; and/or

· license technology from the third party claiming infringement, which license may not be available on commercially reasonable terms.

The occurrence of any of the foregoing could result in unexpected expenses or require Protonex to recognize an impairment of Protonex’s assets, which would reduce the value of Protonex’s assets and increase expenses. In addition, if Protonex alters or discontinues Protonex’s offering of affected products, Protonex’s revenue could be affected. If a claim of infringement were successful against Protonex or Protonex’s clients, an injunction might be ordered against Protonex’s client or Protonex’s own services or operations, causing further damages.

Protonex expects that the risk of infringement claims against Protonex will increase if Protonex’s competitors are able to obtain patents or other intellectual property rights for software products and methods, technological solutions, and processes. Protonex may be subject to intellectual property infringement claims from certain individuals or companies who have acquired patent portfolios for the primary purpose of asserting such claims against other companies. The risk of infringement claims against Protonex may also increase as Protonex continues to develop Protonex’s intellectual property and sell additional products. Any infringement claim or litigation against Protonex could have a material adverse effect on Protonex’s business, results of operations and financial condition.

Protonex may fail to adequately protect Protonex’s proprietary technology, which would allow competitors or others to take advantage of Protonex’s research and development efforts.

Protonex relies upon trade secrets, proprietary know-how, and continuing technological innovation to develop new products and to remain competitive. If Protonex’s competitors learn of Protonex’s proprietary technology or processes, they may use this information to produce products that are equivalent or superior to Protonex’s products, which could materially adversely affect Protonex’s business, operations and financial position. Protonex’s employees and consultants may breach their obligations not to reveal Protonex’s confidential information, and any remedies available to Protonex may be insufficient to compensate Protonex’s damages. Even in the absence of such breaches, Protonex’s trade secrets and proprietary know-how may otherwise become known to Protonex’s competitors, or be independently discovered by Protonex’s competitors, which could adversely affect Protonex’s competitive position.

Protonex relies on third parties for the manufacture of certain product components.

Protonex purchases the components and equipment it needs to manufacture its fuel cell and power management systems from various manufacturers and does not produce them itself. The supplier industry for Protonex components is, however, only partially prepared for the specific requirements of the developing mass market for fuel cells and power managers. To avoid overdependence on certain suppliers, Protonex is working to diversify its suppliers and is entering into intensive cooperative projects to that end. Arrangements have been made with suitable second suppliers for some components. Supply chain risks are being reduced through professional quality management and supplier management. Nevertheless, insufficient availability of all components procured from suppliers poses a risk in the event that these components cannot be made available on time, at the planned cost, or in the required quality. There is also the risk of the loss of a supplier. Another risk is having claims asserted against Protonex if Protonex is unable to make all deliveries under master agreements, based on inability to procure components within the planned time or cost.

Financial and Liquidity Risks

Protonex’s strategic orientation requires continued expenditures, which must be financed to ensure future business success, particularly in the areas of product development and tapping additional market segments and new regions. Thanks to Protonex’s customer structure (high percentage of industrial customers, military customers), there were no significant payment defaults in 2014 not addressed through write-downs. However, as Protonex expands sales to commercial customers and foreign governments, payment defaults could increase.

28

Table of Contents

Regulatory risks

The business in which Protonex operates is often regulated. That is because it produces, distributes, and markets complex technical products, distributes them in markets with demanding safety requirements (such as military organizations), and is subject to highly complex, sometimes non-uniform regulatory background conditions in various markets and countries.

Protonex depends on a small number of large customers and the loss of one or more major customers could have a material adverse effect on Protonex’s business, financial condition and results of operations.

For the fiscal year ended September 30, 2014, Protonex’s top five customers, in aggregate, generated approximately 79% of Protonex’s revenue with no one customer representing greater than 37%. Protonex expects that Protonex’s top five customers will continue to account for a significant portion of Protonex’s revenue for the foreseeable future. For fiscal year 2014, one large customer constituted approximately 37% of total revenues. For fiscal year 2015 YTD, two large customers constituted approximately 40% and 12% of total revenues, respectively. It is possible that any of Protonex’s large customers could decide to terminate their relationships with Protonex. The loss of one or more of Protonex’s top five customers, or a substantial decrease in demand by any of those customers for Protonex’s products, could have a material adverse effect on Protonex’s business, and result in a decline in financial condition. Additionally, Protonex’s large customers have substantial negotiating leverage, which may require that Protonex agree to terms and conditions that result in increased cost of sales, decreased revenues and lower average selling prices and gross margins, all of which could harm Protonex’s operating results.

If Protonex’s products or systems experience data security breaches or there is unauthorized access to or release of Protonex’s customers’ data, Protonex may lose current or future customers and Protonex’s reputation and business may be harmed and may incur liabilities to repair or replace Protonex’s systems or in connection with litigation or regulatory enforcement actions that may result from such breaches.

If Protonex’s security measures are breached as a result of a third-party action, employee error or otherwise, and as a result customers’ information becomes available to unauthorized parties, Protonex could incur liability, Protonex may lose revenues and Protonex’s reputation would be damaged. This could lead to the loss of current and potential customers. If Protonex experiences any breaches of Protonex’s network security due to unauthorized access, sabotage, or human error, Protonex may be required to expend significant capital and other resources to remedy, protect against or alleviate these and related problems. Protonex also may not be able to remedy these problems in a timely manner, or at all. Even the perception that the customer information is not satisfactorily protected or does not meet regulatory requirements or that Protonex’s systems are unsecure or unstable could inhibit sales of Protonex’s products, and could limit adoption of Protonex’s products. The property and business interruption insurance Protonex carries may not provide coverage adequate to compensate Protonex fully for losses that may occur or litigation that may be instituted against Protonex in these circumstances. Protonex could be required to make significant expenditures to repair Protonex’s systems in the event that they are damaged or destroyed, or if the delivery of Protonex’s services to Protonex’s customers is disrupted, and Protonex’s business and results of operations could be harmed.

Protonex faces intense and growing competition. If Protonex is unable to compete successfully, Protonex’s business will be seriously harmed through loss of customers or increased negative pricing pressure.

The market for Protonex’s products is extremely competitive. Protonex’s competitors vary in size and in the variety of products.

Some of Protonex’s current and potential direct competitors have longer operating histories, significantly greater financial, technical, marketing and other resources than Protonex does, greater brand recognition and, Protonex believes, a larger base of customers. In addition, competitors may operate more successfully or form alliances to acquire significant market share. These direct competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements. They may also be able to devote more resources to the promotion, sale and development of their products than Protonex and there can be no assurance that Protonex’s current and future competitors will not be able to develop products comparable or superior to those offered by Protonex at more competitive prices. As a result, in the future, Protonex may suffer from an inability to offer

29

Table of Contents

competitive products or be subject to negative pricing pressure that would adversely affect Protonex’s ability to generate revenue and adversely affect Protonex’s operating results.

Protonex’s business will be adversely affected if Protonex cannot successfully retain key members of Protonex’s management team or retain, hire, train and manage other key employees, particularly in the engineering, sales and customer service areas.

Protonex’s continued success is largely dependent on the personal efforts and abilities of Protonex’s executive officers and senior management, including Protonex’s President and Chief Executive Officer and Protonex’s executive management team. Protonex’s success also depends on Protonex’s continued ability to attract, retain, and motivate key employees throughout Protonex’s business. In particular, Protonex is substantially dependent on Protonex’s skilled technical employees and Protonex’s sales and customer service employees. Competition for skilled technical, sales and customer service professionals is intense and Protonex’s competitors often attempt to solicit Protonex’s key employees and may be able to offer them employment benefits and opportunities that Protonex cannot. There can be no assurance that Protonex will be able to continue to attract, integrate or retain highly qualified personnel in the future. In addition, Protonex’s ability to achieve significant growth in revenue will depend, in large part, on Protonex’s success in effectively training sufficient numbers of technical, sales and customer service personnel. New employees require significant training before they achieve full productivity. Protonex’s recent and planned hires may not be as productive as anticipated, and Protonex may be unable to hire sufficient numbers of qualified individuals. If Protonex is not successful in retaining Protonex’s existing employees, or hiring, training and integrating new employees, or if Protonex’s current or future employees perform poorly, growth in the sales of Protonex’s services may not materialize and Protonex’s business will suffer.

Protonex’s sales cycle is lengthy and variable, depends upon many factors outside Protonex’s control, and could cause Protonex to expend significant time and resources prior to earning associated revenues.

The typical sales cycle for Protonex’s products and services is lengthy and unpredictable, requires evaluation by a significant number of employees in Protonex’s customers’ organizations, and often involves a significant operational decision by Protonex’s customers. Protonex’s sales efforts involve educating Protonex’s customers about the use and benefits of Protonex’s products, including the technical capabilities of Protonex’s products and the potential cost savings achievable by organizations deploying Protonex’s products. Customers typically undertake a significant evaluation process, which frequently involves not only Protonex’s products, but also those of Protonex’s competitors and can result in a lengthy sales cycle. Moreover, a purchase decision by a potential customer typically requires the approval of several senior military and / or civilian decision makers. Protonex’s sales cycle for new customers is typically one to two years and can extend even longer in some cases. Protonex spends substantial time, effort and money in Protonex’s sales efforts without any assurance that Protonex’s efforts will produce any sales. In addition, Protonex sometimes commits to include specific functions in Protonex’s base product offering at the request of a customer or group of customers and are unable to recognize product revenues until the specific functions have been added to Protonex’s products. Providing this additional functionality may be time consuming and may involve factors that are outside of Protonex’s control. The lengthy and variable sales cycle may also have a negative impact on the timing of Protonex’s revenues, causing Protonex’s revenues and results of operations to vary significantly from period to period.

Failure to meet customer expectations on the implementation of Protonex’s products could result in negative publicity and reduced sales, both of which would significantly harm Protonex’s business, results of operations, financial condition and growth prospects.

Protonex provides its customers with upfront estimates regarding the duration, budget and costs associated with development efforts. Failing to meet these upfront estimates and the expectations of Protonex’s customers for Protonex’s development efforts could result in a loss of customers and negative publicity regarding Protonex and Protonex’s products and services, which could adversely affect Protonex’s ability to attract new customers and sell additional products and services to existing customers. Such failure could result from Protonex’s product and/or development capabilities. The consequences could include customer’s refusal to pay the products or service. In addition, cost overruns on development projects increase Protonex’s costs and adversely affecting Protonex’s business results and financial condition.

Table of Contents

If Protonex is unable to develop, introduce and market new and enhanced versions of Protonex’s products, Protonex may be put at a competitive disadvantage.

Protonex’s success depends on Protonex’s continued ability to develop, introduce and market new and enhanced versions of Protonex’s products to meet evolving customer requirements. However, Protonex cannot guarantee that this process can be maintained. If Protonex fails to develop new products or enhancements to Protonex’s existing products, Protonex’s business could be adversely affected, especially if Protonex’s competitors are able to introduce products with enhanced functionality. Protonex plans to continue Protonex’s investment in product development in future periods. It is critical to Protonex’s success for Protonex to anticipate changes in technology, industry standards and customer requirements and to successfully introduce new, enhanced and competitive products to meet Protonex’s customers’ and prospective customers’ needs on a timely basis. However, there can be no assurance that revenues will be sufficient to support the future product development that is required for Protonex to be competitive. Although Protonex may be able to release new products in addition to enhancements to existing products, Protonex cannot guarantee that Protonex’s new or upgraded products will be accepted by the market, will not be delayed or canceled, will not contain errors or “bugs” that could affect the performance of the products or cause damage to users’ equipment, or will not be rendered obsolete by the introduction of new products or technological developments by others. If Protonex fails to develop products that are competitive in technology and price or that fail to meet customer needs, Protonex’s market share will decline and Protonex’s business and results of operations could be harmed.

Litigation could result in substantial costs to Protonex and Protonex’s insurance may not cover these costs.

There is a risk that Protonex’s products may not perform up to expectations. While Protonex attempts to contractually limit Protonex’s liability for damages arising from the use of Protonex’s products, there can be no assurance that they will be enforceable in all circumstances or in all jurisdictions. Furthermore, litigation, regardless of contractual limitations, could result in substantial cost to Protonex’s divert management’s attention and resources from Protonex’s operations and result in negative publicity that Protonex’s ongoing marketing efforts and therefore Protonex’s ability to maintain and grow Protonex’s customer base. Although Protonex has general liability insurance in place, there is no assurance that this insurance will cover these claims or that these claims will not exceed the insurance limit under the company’s current policies.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This proxy statement/prospectus and the documents incorporated by reference herein contain certain “forward-looking information” and “forward-looking statements” as defined under applicable Canadian and U.S. securities laws (collectively, “forward-looking statements”). All statements, other than statements of historical fact, are forward-looking statements. When used in this proxy statement/prospectus, the words “estimate,” “project,” “believe,” “anticipate,” “intend,” “expect,” “plan,” “predict,” “may,” “should,” “will,” “could” or the negatives of these words or other variations thereof and comparable terminology are intended to identify forward-looking statements. Also, as examples, forward-looking statements may include statements concerning future results from operations, financial position, economic conditions, product releases, revenue and product synergies, cost savings, product or competitive enhancements and any other statement that may be construed as a prediction of future performance or events, including the unaudited pro forma consolidated financial data included herein, perceived benefits from the business combination to the combined company, or that the acquisition will result in increased revenue, cost savings and better competitive position, or that Ballard will successfully integrate Protonex’s business and technology. These forward-looking statements involve certain known and unknown risks and uncertainties. Factors that could cause actual results to differ materially from those contemplated by the forward-looking statements include, but are not limited to, the following factors:

· the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement;

· the inability to complete the Merger within the expected time period or at all, including due to the failure to obtain stockholder approval, or the failure to satisfy other conditions to completion of the Merger;

· risks related to disruption of management’s attention from the ongoing business operations due to the Merger; the effect of the announcement of the Merger on the Ballard’s or Protonex’s relationships with their respective customers, lenders, operating results and businesses generally;

· material adverse changes in Ballard’s or Protonex’s operations or financial results prior to closing;

· the ability to expand the combined company’s global reach and accelerate growth;

· failure to realize anticipated operational efficiencies, revenue (including projected revenue) and cost synergies and resulting revenue growth if the Merger is consummated;

· the ability to achieve internal strategic forecasts;

· inability to refinance the assumed Protonex debt subsequent to the closing or to refinance the debt on favorable terms;

· unforeseen challenges related to relationships with operators, publishers and advertisers and expanding and maintaining those relationships;

· the ability to execute upon, and realize any benefits from, potential value creation opportunities through strategic relationships in the future or at all, including the ability to leverage advertising opportunities effectively and increase revenue streams for carriers; and

· the potential for unforeseen or underestimated cash requirements necessary to enable the Merger synergies to be realized.

See also the section entitled “Risk Factors” in this proxy statement/prospectus and the documents incorporated by reference herein. These risks and uncertainties are not exhaustive. Other sections of this proxy statement/prospectus describe additional factors that could adversely impact the combined company’s business and financial performance. Moreover, the combined company will operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible to predict all risks and uncertainties, nor can we assess the impact that these factors will have on the combined company’s business or the extent to which any factor,

or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement.

Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected. We caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made. Although we have attempted to identify important factors that could cause actual results to differ materially from forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated, described or intended. We disclaim any obligation subsequently to revise any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect changes in assumptions or the occurrence of anticipated or unanticipated events, except as required by law. Except for our ongoing obligation to disclose material information under U.S. federal securities laws, we undertake no obligation to release publicly any revisions to any forward-looking statements, to report events, or to report the occurrence of unanticipated events.

We expressly qualify in their entirety all forward-looking statements attributable to Ballard, Protonex or the combined company, or any person acting on their behalf, by the foregoing cautionary statements.

SPECIAL MEETING OF PROTONEX STOCKHOLDERS

Date, Time and Place

This proxy statement/prospectus is furnished in connection with the solicitation by the Board of Directors of Protonex of proxies to be voted at a special meeting of stockholders of Protonex to be held at 10:00 a.m. E.D.T. on September 15, 2015 at the offices of Protonex, 153 Northboro Road, Southborough, Massachusetts 01772-1034, United States, and any and all adjournments thereof, for the purpose set forth in the accompanying Notice of Special Meeting. This proxy statement/prospectus is first being furnished to our stockholders on or about August 17, 2015.

Purpose of Protonex Special Meeting

The purpose of the Meeting is for Protonex stockholders to consider and vote upon the proposal to adopt and approve the Merger Agreement by and among Ballard, Merger Sub, and Protonex, pursuant to which Merger Sub will merge with and into Protonex, with Protonex surviving as a wholly-owned subsidiary of Ballard, and Ballard will issue common shares to the stockholders of Protonex in exchange for all issued and outstanding shares of Protonex common stock, as more fully described in the attached proxy statement/prospectus. A copy of the Merger Agreement is attached as Appendix A to the accompanying proxy statement/prospectus, and to act on such other matters as may be properly brought before the special meeting, or any adjournment or postponement thereof.

Record Date, Outstanding Shares and Quorum

Only stockholders of record at the close of business on August 11, 2015, the record date, are entitled to notice of, and to vote at, the special meeting and at any adjournment thereof. As of such date, there were 64,978,500 shares of common stock of Protonex issued and outstanding. Each share is entitled to one vote with respect to all matters to be acted upon at the special meeting. The holders of one-third of Protonex’s common stock outstanding and entitled to vote, represented at the special meeting in person or by proxy, shall constitute a quorum for the transaction of business.

Share Ownership by, and Voting Rights of, Protonex’s Directors and Executive Officers

When considering the recommendation of Protonex’s board of directors, you should be aware that certain of our executive officers and directors have interests in the Merger other than their interests as Protonex’s stockholders generally, as well as pursuant to individual agreements with certain officers and directors. These interests are different from your interests as an Protonex stockholder, however, the members of our board of directors have taken these additional interests into consideration.

A “change in control” for purposes of the individual award agreements, employment agreements, and Protonex plans discussed below is deemed to occur upon, among other things, the consummation of a merger or consolidation of Protonex with or into another entity. The Merger will constitute a change in control for purposes of these agreements and plans.

Certain of our directors and executive officers hold stock options to acquire shares of our common stock. Pursuant to their award agreements under Protonex’s equity compensation plans, one half of any stock options issued to the directors and executive officers in their capacity as directors and executive officers and that remain unvested will become fully vested and exercisable prior to the change in control of Protonex.

At the close of business on the record date for the special meeting, Protonex’s directors and executive officers and their affiliates beneficially owned and had the right to vote approximately 14,214,453 shares of Protonex common stock at the special meeting, which represents approximately 21.9% of the Protonex common stock entitled to vote at the special meeting. Certain of Protonex’s directors, beneficial owners of Protonex common stock, and executive officers have entered into support agreements with Ballard pursuant to which they have agreed to vote their shares “FOR” the adoption of the Merger Agreement. It is expected that Protonex’s executive officers will vote their shares “FOR” the adoption of the Merger Agreement.

How to Vote

If you are entitled to vote at the special meeting and hold your shares in your own name, you can submit a proxy or vote in person by completing a ballot at the special meeting. However, Protonex encourages you to submit a proxy before the special meeting even if you plan to attend the special meeting in order to ensure that your shares are voted. A proxy is a legal designation of another person to vote your shares of Protonex common stock on your behalf. If you hold shares in your own name, you may submit a proxy for your shares by filling out, signing and dating the enclosed proxy card and mailing it in the prepaid envelope included with these proxy materials. Protonex encourages its stockholders to submit their proxies using this method whenever possible.

Stockholders Sharing an Address

Only one copy of this proxy statement/prospectus is being delivered to Protonex stockholders residing at the same address, unless Protonex stockholders have notified Protonex of their desire to receive multiple copies of this proxy statement/prospectus. This is known as householding.

Protonex will promptly deliver, upon oral or written request, a separate copy of this proxy statement/prospectus to any Protonex stockholder residing at an address to which only one copy was mailed. Stockholders who do not receive a separate copy of this proxy statement/prospectus and who want to receive a separate copy may request to receive a separate copy of this proxy statement/prospectus by writing to Investor Relations at Protonex Technology Corporation, 153 Northboro Road, Southborough, Massachusetts 01772-1034, United States. Protonex undertakes to deliver promptly a copy of this proxy statement/prospectus upon the receipt of such request. Stockholders who share an address and receive multiple copies of this proxy statement/prospectus may also request to receive a single copy by following the instructions above.

Revocation of Proxies

You may revoke your proxy and/or change your vote at any time before your proxy is voted at the special meeting. If you are a stockholder of record, you can do this by:

· sending a written notice stating that you revoke your proxy to Protonex at, Protonex Technology Corporation, Attention: Corporate Secretary, 153 Northboro Road, Southborough, Massachusetts 01772-1034, United States that bears a date later than the date of the proxy and is received prior to the special meeting and states that you revoke your proxy;

· submitting a valid, later-dated proxy by mail that is received prior to the special meeting; or

· attending the Meeting and voting by ballot in person (your attendance at the special meeting will not, by itself, revoke any proxy that you have previously given).

If you hold your shares of Protonex common stock in “street name” through a broker, bank or other nominee, you must follow the directions you receive from your broker, bank or other nominee in order to revoke or change your vote.

Voting Your Shares

All shares represented by each properly executed and valid proxy received before the special meeting will be voted in accordance with the instructions given on the proxy. If a Protonex stockholder executes a proxy card without giving instructions, the shares of Protonex common stock represented by that proxy card will be voted in accordance with the recommendations of Protonex board of directors.

Please submit your proxy by mail, whether or not you plan to attend the special meeting in person.

Votes Required

The approval of the Merger Agreement requires the affirmative vote of the shares representing a majority of the outstanding shares of Protonex common stock entitled to vote at the special meeting.

Abstentions and Broker Non-Votes

If you abstain from voting, either in person or by proxy, or do not instruct your broker or other nominee how to vote your shares, it will have the same effect as a vote “AGAINST” the Merger Agreement.

Proxy Solicitation

Protonex will pay the cost of distributing and soliciting proxies. This proxy solicitation is being made by Protonex on behalf of its board of directors.

Protonex will also request brokers and other fiduciaries to forward proxy solicitation material to the beneficial owners of shares of Protonex common stock that the brokers and fiduciaries hold of record.

Stockholders should not send stock certificates with their proxies. If approved, a letter of transmittal and instructions for the surrender of Protonex common stock certificates will be mailed to Protonex stockholders shortly after the completion of the Transaction.

THE MERGER PROPOSAL

The following is a description of the material aspects of the Merger. While we believe that the following description covers the material terms of the Merger, the description may not contain all of the information that is important to Ballard stockholders and Protonex stockholders. We encourage you to carefully read this entire proxy statement/prospectus, including “Merger Agreement” starting on page 56 and the Merger Agreement attached to this proxy statement/prospectus as Appendix A, for a more complete understanding of the Merger.

Overview

The Ballard and Protonex boards of directors approved, and, on June 29, 2015, Ballard and Protonex entered into, the Merger Agreement, which provides for Merger Sub, a newly formed and wholly-owned subsidiary of Ballard, to be merged with and into Protonex, with Protonex surviving the Merger as a wholly-owned subsidiary of Ballard.

At the effective time of the Merger, on the terms and subject to the conditions set forth in the Merger Agreement, each share of Protonex common stock outstanding immediately prior to the effective time, other than common shares held by stockholders that exercise appraisal rights under applicable law, will be converted into the right to receive a number of Ballard common shares, equal to (i) U.S.$30,000,000 million less Protonex’s net debt and transaction expenses at the time of closing, divided by U.S. $2.28 divided by; (ii) the number of shares of Protonex common stock issued and outstanding immediately prior to closing.

Ballard expects to issue, pursuant to the Merger Agreement, up to 11,214,912 common shares (including 628,732 shares to be deposited into escrow). On a per share basis, you will be entitled to receive approximately 0.1562 of a Ballard common share for each share of Protonex common stock you hold as of the effective time of the Merger. The aggregate number Ballard common shares to be issued pursuant to the Merger Agreement will vary depending on a number of factors, including the amount of the estimated net debt of Protonex at closing. The Merger Agreement does not provide for an adjustment in the aggregate number of Ballard common shares to be issued by Ballard to Protonex’s stockholders in the Merger in the event of fluctuations in the market value of Ballard’s common shares up through the closing date. However, the number of shares to be issued by Ballard pursuant to the Merger Agreement is subject to adjustment based on Protonex’s net debt as of the closing date of the Merger. We currently estimate that, if the Merger closes on September 30, 2015, Ballard would issue 11,214,912 shares (including 628,732 shares to be deposited into escrow), which would represent approximately 7.3% of Ballard’s outstanding common shares as of the date of this proxy statement/prospectus (after giving effect to such issuance), assuming Protonex net debt and transaction expenses equal U.S. $4,430,000. Protonex’s actual results of operations between the date of the financial information included in this proxy statement/prospectus and the closing date may differ from the forecasted results used in this estimate, resulting in differences between the forecast and actual amounts of Protonex’s net debt, including transaction expenses, as of the closing date of the Merger. See “Merger Agreement” on page 56 of this proxy statement/prospectus for further information relating to the potential amount of shares to be issued by Ballard in the Merger.

Pursuant to an escrow agreement to be entered into between Ballard, Edward J. Stewart, as stockholder representative, and U.S. Bank, National Association, as escrow agent, Ballard will deposit approximately 628,732 common shares payable to the Supporting Stockholders, or 10% of the total Merger consideration payable to the Supporting Stockholders, into an escrow account maintained by the escrow agent. These common shares will be used to cover indemnification claims by Ballard pursuant to the terms of the Merger Agreement, which shares will be released 12 months after the closing of the Merger, subject to any then pending claims.

In addition, each of the Protonex stockholders that executed a support agreement has agreed that the Ballard common shares to be received by such Supporting Stockholder in the Merger are subject to lock-up restrictions, which restrictions will lapse with respect to one-half of such Ballard common shares at the six and 12-month anniversaries of the closing date of the Merger. Such Supporting Stockholder has agreed not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any Ballard common shares during the lock-up period.

Background of the Merger

The management of Protonex continually evaluates opportunities to achieve growth for the business, both through organic measures as well as through M&A activities such as acquisitions and business combinations. In the fall of 2013, the management of the Protonex hired financial advisors KPMG Corporate Finance LLC (“KPMG”) on an exclusive basis to explore strategic alternatives, including a potential sale of the business. Under this engagement, Protonex management and its advisors reviewed and considered various strategic opportunities available in the form of a possible sale of the business, or a business combination with a third party. Management and its advisors held various conversations with representatives of prospective acquirers and investors in connection with potential business combination transactions. None of these conversations or activities ultimately progressed to an executed, non-binding term sheet with the exception of discussions held with Ballard.

Protonex management began discussions with representatives of Ballard in the spring of 2014 toward the possibility of a strategic combination of the businesses. These discussions were primarily held between Protonex executives Dr. Paul Osenar (President and CEO), Chris Schuster (CFO and Treasurer) and Phil Robinson (VP of Electronics and Power Systems), and Ballard representatives Karim Kassam (VP of Corporate Development) and Kevin Colbow (VP of Technology Solutions).

On March 5, 2014, the two parties entered into a confidentiality agreement relating to a potential transaction; however, the parties were unable to agree to terms, and discussions were discontinued for a period of time. In the first quarter of calendar year 2015, as a result of ongoing internal discussions and continued interest, Ballard resumed discussions with Protonex management regarding the opportunity for a transaction. A number of additional discussions took place, including in-person meetings between representatives of Protonex and Ballard at KPMG’s offices in Chicago on March 16, 2015 and at Protonex’s Massachusetts facility on April 15, 2015.

On April 30, 2015, Ballard delivered a preliminary term sheet formally expressing Ballard’s interest in pursuing an acquisition of Protonex, with key terms including a 60-day period of exclusivity. Protonex management, together with representatives of KPMG, reviewed the term sheet to assess the suitability of the terms and the related proposed transaction, as well as identify any terms which might be of particular concern to the board and/or Protonex stockholders. On May 7, 2015, a meeting of the Protonex board of directors was held, in which the board reviewed the preliminary term sheet extensively and agreed on revising certain elements. Protonex delivered the agreed-upon revised terms, including an increase in the proposed purchase price, to Ballard.

Following discussions between Protonex management and Ballard on proposed purchase price, structure and terms, which included a visit by Dr. Osenar and Mr. Robinson to Ballard’s Vancouver, British Columbia operations to meet with Ballard management and discuss a potential transaction, Ballard delivered a revised term sheet on May 13, 2015. The term sheet provided for consideration to be paid in Ballard common stock, with the assumption of all Protonex indebtedness, and called for certain closing conditions including formal approval by Ballard’s board of directors, and receipt of required consents and regulatory approvals. Following ongoing consultation with Protonex’s board of directors and KPMG advisors, Dr. Osenar executed the non-binding term sheet on May 20, 2015.

Following execution of the revised term sheet, Ballard, along with its advisors, launched comprehensive due diligence efforts into the business and financial condition of Protonex through conference calls, on-site meetings, and review of diligence information provided through a virtual data room. On June 8, 9, and 10, 2015, representatives of Ballard visited Protonex headquarters for further diligence meetings and to facilitate direct interaction with various counterparts in operations, engineering, human resources, sales, and finance and accounting. These on-site meetings included discussions on the organization of the combined operations upon consummation of a potential transaction. Ballard attendees on this visit included Mr. Guglielmin, Mr. Kassam and other vice presidents and senior business leaders.

From late May 2015 until late June 2015, the parties and their respective outside legal counsel engaged in intense negotiations regarding the provisions contained in the Merger Agreement and Support Agreement.

The specific terms of a Merger agreement were approved by the Protonex’ Board of Directors on June 23 and by Ballard’s Board of Directors on June 26 th 2015. The finalized merger agreement was signed by both parties effective June 29th 2015.

Recommendations of the Protonex Board of Directors; Protonex’s Reasons for the Transaction

On June 23, 2015, the Protonex board of directors approved the Merger Agreement and recommended that Protonex stockholders adopt the Merger Agreement and approve the Merger. In considering reasons for the Merger, stockholders should be aware that Protonex directors may have interests in the Merger that may be different from, or in addition to, the interests of Protonex stockholders generally. In reaching the decision to approve the Merger Agreement, the Protonex board of directors consulted with management and legal advisors, reviewing a number of materials and considering many factors, including:

· The value of the consideration to be received by stockholders;

· The form of consideration in Ballard common stock, and the opportunity for potential stock price appreciation of the combined entity;

· The potential liquidity Ballard common stock might provide Protonex’ stockholders;

· The potential for limited tax consequences to stockholders;

· Protonex’s financial and operating conditions, including the ability to meet short and long term liquidity needs while providing a platform to expand the footprint for Protonex products;

· Current and prospective industry, economic and market trends;

· Future prospects of Protonex as an independent entity in comparison with a merger formation, including financial and other risks;

· The financial and operating conditions, and future business prospects of Ballard;

· Strategic advantages of combined business with Ballard;

· Analysis of potential alternatives to a merger;

· The degree of certainty associated with the terms of the definitive purchase agreement and other transaction documents taken as a whole; and

· The agreement that the terms of the definitive purchase agreement are fair and reasonable.

The Protonex board of directors also considered possible negative factors to the adoption of the Merger Agreement and potential Merger, including:

· There is no assurance that all the necessary conditions to consummate the Merger, including any regulatory approval, will be sufficiently satisfied;

· The limitations on strategic, financial and operating decisions imposed on Protonex while closing activities are being completed;

· The risk of stock price depreciation for Ballard prior to the consummation of the Merger, and for the combined entity after the consummation of the Merger, in the event of poor financial results or adverse market perception, given the consideration is offered in a fixed number of Ballard shares;

· The limits placed on liquidity for some of the Protonex’ stockholders based on the lock up requirements; and

· The challenges associated with combining the operations of the businesses.

The members of the Protonex board of directors considered the above and other factors, both potentially positive and negative, and concluded that, overall, the potentially positive factors outweighed the negative factors. As a result, the Protonex board of directors concluded that the proposed Merger is advisable and fair to stockholders, and approved the Merger Agreement, recommending that Protonex stockholders also adopt and approve the Merger Agreement and related Merger.

Disclaimer/Forward-Looking Statements: The foregoing is not intended as an exhaustive list of information and factors considered by the Protonex board of directors in their consideration of the proposed Merger, but is provided as a summary of the key factors and information considered. Members of the board did not seek to make a determination on any specific factor or sub-set of factors, but arrived at the decision to approve the Merger Agreement and the Merger based on the totality of information presented at the time, including the above and other factors. The explanation of Protonex’s reasons for the Merger provided in this section is forward-looking in nature, and is based on current expectations and assumptions of future performance, of which many are beyond the control of the Protonex board of directors and management. Since they are based in the future, expectations held by the

board and management are inherently subject to risks and uncertainties. Should expectations not come to fruition, the actual results, performance or achievements of the contemplated merger may vary materially from those potential outcomes described above.

Interests of Certain Protonex Directors, Officers, and Affiliates in the Merger

When considering the recommendation of Protonex’s board of directors, you should be aware that certain of Protonex’s executive officers and directors have interests in the Merger other than their interests as Protonex stockholders generally, pursuant to individual agreements with certain officers and directors. These interests are different from your interests as a Protonex stockholder, however, the members of Protonex’s board of directors have taken these additional interests into consideration.

The table below shows, for each of Protonex’s directors and executive officers who beneficially own Protonex common stock, the number of shares of common stock held by such person and gives effect to the acceleration of vesting of certain options that would occur upon a consummation of the Merger:

Directors and Executive Officers: |  | Total Shares of Protonex Common Stock Owned(1) |  | Percent of Total Common Stock(4) |  | Value of Such Stock in Merger(1)(5) |

(5) | Net value of shares, and options, assuming a cashless exercise. The calculation provided is based on the closing share price of a Ballard common share on the NASDAQ of U.S. $1.33 on August 5, 2015.

Certain of Protonex directors and executive officers hold stock options to acquire shares of Protonex common stock. Pursuant to their award agreements under Protonex’s equity compensation plans, one-half of any stock options issued to the directors and executive officers in their capacity as directors and executive officers and that remain unvested will become fully vested and exercisable prior to the date of the change in control as set forth below. A “change in control” for purposes of the individual award agreements, employment agreements, and Protonex plans discussed below is deemed to occur upon, among other things, the consummation of a merger or consolidation of Protonex with or into another entity. The Merger will constitute a change in control for purposes of these agreements and plans. Any options that are not converted into common shares of Ballard in connection with the Merger will terminate upon the consummation of the Merger.

Executive Officer/Director: |  | Option Shares of Protonex to Accelerate Upon Change of Control |
John N. Butt |  | 0 |
Edward J. Stewart |  | 71,250 |

In addition, completion of the Merger will trigger change of control bonus payments to certain executive officers of Protonex (the “Merger Bonuses”). The executive officers will be eligible to receive Merger Bonuses in amounts totaling U.S. $260,000 as set forth below. The Merger Bonuses are to be issued in lieu of annual bonuses to those executive officers, which were scheduled to be amounts equal to two-thirds of the Merger Bonuses.

Exchange of Shares in the Merger

Ballard will appoint Computershare Investor Services Inc., as exchange agent in connection with the Merger, to handle the exchange of shares of Protonex common stock for Ballard shares. Shares of Protonex common stock will be automatically converted into the right to receive Ballard common shares without the need for any action by the holders of shares of Protonex common stock, provided that holders of shares of Protonex common stock who have properly and validly exercised and perfected their right to dissent shall not have their shares automatically converted.

Within three business days of the effective time of the Merger, the exchange agent will send to each Protonex stockholder of record a letter of transmittal. The letter of transmittal will specify that delivery will be effected, and risk of loss and title to any certificates shall pass, only upon proper delivery of such certificates to the exchange agent. The letter of transmittal will be accompanied by instructions. Protonex stockholders should not return share certificates with the enclosed proxy card.

After the effective time, shares of Protonex common stock will no longer be outstanding, will be automatically cancelled and will cease to exist and each certificate, if any, that previously represented shares of Protonex common stock will represent only the right to receive the Merger consideration as described above. Until holders of shares of Protonex common stock have surrendered such shares to the exchange agent for exchange, those holders will not receive the Merger consideration or any dividends or distributions on Ballard shares into which their shares of Protonex common stock have been converted with a record date after the effective time.

Protonex stockholders will not receive any fractional Ballard common shares pursuant to the Merger. Each holder of Protonex common stock exchanged pursuant to the Merger Agreement who would otherwise have been entitled to receive a fraction of a Ballard common share (after taking into account all share certificates delivered by such holder) will receive, in lieu of such fractional share, the number of Ballard common shares rounded down to the nearest whole number. The rounding of fractional Ballard common shares was not separately bargained for consideration but merely represents a mechanical rounding off for purposes of simplifying the corporate and accounting problems that would otherwise be caused by the issuance of fractional Ballard common shares.

Effect of Options and Warrants in the Merger

In accordance with the Merger Agreement and Protonex’s 2003 Stock Incentive Plan and 2013 Stock Incentive Plan, holders of options to purchase Protonex common stock must exercise such options by the fifth business day prior to the special meeting of Protonex stockholders, or their options will be cancelled. In addition, under the Merger Agreement, Protonex has agreed to cause all outstanding warrants to purchase Protonex common stock to be exercised or terminated prior to the effective time of the Merger. Ballard will not assume any Protonex options, warrants or other derivative securities in connection with the Merger, and you will receive no Merger consideration in exchange for such securities. Any Protonex options or warrants duly exercised for shares of Protonex common stock prior to the effective time of the Merger will be entitled to the Merger consideration for their shares of common stock held at the effective time.

Listing of Ballard Common Shares

It is a condition to the completion of the Merger that the Ballard common shares issuable in the Merger or after the Merger in respect of Protonex equity awards be approved for listing on the NASDAQ and TSX, subject, in the case of the TSX, to the making of certain prescribed filings as soon as possible following the completion of the Merger. As of the date of this proxy statement/prospectus, the application for approval of the listing of the common shares of Ballard issuable in the Merger has been submitted to the TSX. A listing of additional shares notification will be provided to the NASDAQ in accordance with the requirements of the NASDAQ Stock Market Rules.

Lock-Up Restrictions

In addition, each of the Supporting Stockholders has agreed that the Ballard common shares to be received by such stockholder in the Merger are subject to lock-up restrictions, which restrictions will lapse with respect to one-half of such Ballard common shares at the six and 12-month anniversaries of the closing date of the Merger. Such

44

stockholder has agreed not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any Ballard common shares during the lock-up period.

Material U.S. Federal Income Tax Consequences

The following general discussion sets forth the anticipated material U.S. federal income tax consequences of the Merger and the ownership and disposition of Ballard common shares to U.S. holders (as defined below) of Protonex common stock. This discussion does not address the U.S. federal income tax consequences of transactions taking place prior or subsequent to, or concurrently with, the Merger, whether or not in connection with the Merger. This discussion is based on the Code, applicable Treasury regulations, judicial authority, and administrative rulings, and the Convention between the United States of America and Canada with respect to Taxes on Income and Capital of 1980, as amended, or the “Canada-U.S. tax treaty”, all as of the date of this proxy statement/prospectus, and all of which are subject to change, possibly with retroactive effect.

This discussion is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. holder as a result of the Merger or as a result of the ownership and disposition of Ballard common shares. This discussion does not take into account the individual facts and circumstances of any particular U.S. holder that may affect the U.S. federal income tax consequences to the U.S. holder, including specific tax consequences to a U.S. holder under an applicable tax treaty. Accordingly, this discussion is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any U.S. holder. In addition, this discussion does not address the U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, or non-U.S. tax consequences of the Merger or the ownership and disposition of Ballard common shares.

This discussion addresses only U.S. holders (as defined below) who hold their Protonex common stock, and, after the Effective Time, their Ballard common shares, as a capital asset within the meaning of Section 1221 of the Code. It does not address U.S. holders subject to special tax rules, such as:

· banks, financial institutions, underwriters, or insurance companies;

· real estate investment trusts and regulated investment companies;

· tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts;

· U.S. expatriates or former long-term residents of the United States;

· entities or arrangements that are treated as partnerships for U.S. federal income tax purposes and investors in such partnerships;

· dealers or traders in securities, commodities or currencies;

· grantor trusts;

· S corporations;

· U.S. holders subject to the alternative minimum tax;

· U.S. holders whose “functional currency” is not the U.S. dollar;

· U.S. holders who received Protonex common stock, or, after the Merger, Ballard common shares, through the exercise of options or otherwise as compensation or through a tax-qualified retirement plan;

· U.S. holders who own (directly, indirectly or through attribution) 5% or more by vote or value of the outstanding Protonex common stock, or, after the Merger, of the outstanding Ballard common shares; or

· U.S. holders holding Protonex common stock, or, after the Merger, Ballard common shares, as part of a straddle, synthetic security, hedge, conversion transaction or other integrated investment.

U.S. holders that are subject to special provisions under the Code, including U.S. holders described immediately above, should consult their own tax advisors regarding the U.S. federal income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences of the Merger and the ownership and disposition of Ballard common shares.

As used in this discussion, a “U.S. holder” means a holder of Protonex common stock or, after the Merger, Ballard common shares who is for U.S. federal income tax purposes (i) a citizen or resident of the United States, (ii) a corporation or other entity taxable as a corporation created or organized in or under the laws of the United States or

45

Table of Contents

any state or political subdivision thereof, (iii) a trust that (A) is subject to the primary jurisdiction of a court within the United States and the control of one or more U.S. persons with respect to all of its substantial decisions or (B) has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person, or (iv) an estate that is subject to U.S. federal income tax on its income, regardless of source.

Please consult your own tax advisor as to the specific tax consequences of the Merger and the ownership and disposition of Ballard common shares, including the applicable U.S. federal, state, local and foreign tax consequences to you of the Merger and the ownership and disposition of Ballard common shares.

It is a condition to the completion of the Merger that Protonex and Ballard each receive an opinion from its respective counsel that, for U.S. federal income tax purposes, the Merger should qualify as a reorganization within the meaning of Section 368(a) of the Code. Each counsel’s opinion will be based on qualifications, representations and covenants noted in the opinion (including representations and covenants regarding the absence of changes in existing facts and that the Merger will be completed in accordance with the terms and conditions of the Merger Agreement and as described in this proxy statement/prospectus and on factual representations contained in officer’s certificates of Protonex and Ballard). After Protonex stockholder approval is obtained, neither Protonex nor Ballard may waive the receipt of its counsel’s opinion as a condition to the completion of the Merger, unless this document is recirculated in order to resolicit stockholder approval. If Protonex’s legal counsel, Day Pitney LLP is not willing, able or otherwise fails to deliver such opinion to Protonex, Ballard’s legal counsel, Dorsey & Whitney LLP, may deliver such opinion to Protonex. None of the tax opinions or this summary are binding on the IRS or the courts. In addition, neither Ballard nor Protonex intends to request a ruling from the IRS with respect to the U.S. federal income tax consequences of the Merger and, as a result, there can be no assurance that the IRS will not disagree with any of the conclusions described below. Future legislative, judicial, or administrative changes or interpretations, which may or may not be retroactive, or the failure of any factual representation to be true, correct and complete in all material respects, or the breach of any of the covenants, may adversely affect the accuracy of the statements and conclusions described in this summary.

Material U.S. Federal Income Tax Consequences of the Merger

The Merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code for U.S. federal income tax purposes. If the Merger qualifies as a reorganization under Section 368(a) of the Code, then, subject to Section 367(a) of the Code, as discussed below under the heading “Five Percent Transferee Stockholders”:

· A U.S. holder of Protonex common stock will not recognize income, gain or loss upon the U.S. holder’s receipt of Ballard common shares in exchange for the U.S. holder’s Protonex common stock in the Merger;

· The aggregate tax basis of the Ballard common shares received by a U.S. holder in the Merger will be the same as the aggregate tax basis of the Protonex common stock surrendered in exchange therefor; and

· The holding period for Ballard common shares that a U.S. holder receives in the Merger will include the holding period of the Protonex common stock surrendered in exchange therefor.

If a U.S. holder acquired different blocks of Protonex common stock at different times and at different prices, the U.S. holder’s tax basis and holding period in the Ballard common shares received will be determined by reference to each block of Protonex common stock surrendered.

If the Merger were to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code, then a U.S. holder of Protonex common stock would recognize taxable gain or loss on the Merger equal to the difference, if any, between the fair market value of the Ballard common shares received in the Merger and the U.S. holder’s tax basis in the Protonex common stock surrendered in the Merger. Such gain or loss would be capital gain or loss and would be long-term capital gain or loss if the U.S. holder’s holding period for the U.S. holder’s Protonex common stock is greater than one year. Long-term capital gain of non-corporate stockholders is subject to reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Five Percent Transferee Shareholders

Even if the Merger is afforded non-recognition treatment, a U.S. holder who is a five-percent transferee shareholder, as defined in the applicable Treasury regulations under Section 367(a) of the Code, with respect to Ballard immediately after the Merger will qualify for non-recognition treatment as described in this proxy statement/prospectus only if the U.S. holder files a “gain recognition agreement,” as defined in the regulations, with the IRS. Any U.S. holder of Protonex common stock who will be a five-percent transferee shareholder with respect to Ballard after the Merger should consult with his or her tax advisor concerning the decision to file a gain recognition agreement and the procedures to be followed in connection with that filing.

Dissenting U.S. Holders

A U.S. holder who exercises dissenters’ rights and is paid in cash for all of the U.S. holder’s Protonex common stock will generally recognize gain or loss equal to the difference, if any, between the amount of cash received and the U.S. holder’s tax basis in the Protonex common stock. Gain or loss recognized with respect to cash received pursuant to the exercise of dissenters’ rights will generally be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the Merger, the holding period for the Protonex common stock is greater than one year. The deductibility of capital losses is subject to limitations.

Reporting Requirements

A U.S. holder who is required to file a U.S. federal income tax return and who is a “significant holder” that receives Ballard common shares in the Merger will be required to attach a statement to the U.S. holder’s U.S. federal income tax return for the taxable year in which the Merger is completed that contains the information set forth in Section 1.368-3(b) of the Treasury regulations. The statement attached by the U.S. holder must include the fair market value of, and the U.S. holder’s tax basis in, the Protonex common stock surrendered in the Merger. A “significant holder” generally is a holder of Protonex common stock who, immediately before the Merger, owned at least 5% by vote or value of the total outstanding stock of Protonex.

Ownership and Disposition of Ballard Common Shares

The following discussion is subject to the rules described below under the heading “Passive Foreign Investment Company Rules.”

Taxation of Distributions

A U.S. holder that receives a distribution, including a constructive distribution, with respect to a Ballard common share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any foreign income tax withheld from such distribution) to the extent of the current or accumulated “earnings and profits” of Ballard, as computed for U.S. federal income tax purposes. To the extent that a distribution exceeds the current and accumulated “earnings and profits” of Ballard, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. holder’s tax basis in the Ballard common shares and thereafter as gain from the sale or exchange of such Ballard common shares (see “Sale or Other Taxable Disposition of Ballard Common Shares” below). However, Ballard may not maintain the calculations of earnings and profits in accordance with U.S. federal income tax principles, and each U.S. holder should therefore assume that any distribution by Ballard with respect to the Ballard common shares will constitute ordinary dividend income. Dividends received on Ballard common shares generally will not be eligible for the “dividends received deduction”. Subject to applicable limitations and provided Ballard is eligible for the benefits of the Canada-U.S. Tax Convention, dividends paid by Ballard to non-corporate U.S. holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains for dividends, provided certain holding period and other conditions are satisfied, including that Ballard not be classified as a PFIC (as defined below) in the tax year of distribution or in the preceding tax year. The dividend rules are complex, and each U.S. holder should consult its own tax advisor regarding the application of such rules.

47

Table of Contents

Sale or Other Taxable Disposition of Ballard Common Shares

A U.S. holder will recognize gain or loss on the sale or other taxable disposition of Ballard common shares in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. holder’s tax basis in such Ballard common shares sold or otherwise disposed of. Any such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if, at the time of the sale or other disposition, such Ballard common shares are held for more than one year.

Preferential tax rates apply to long-term capital gains of a U.S. holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gains of a U.S. holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Passive Foreign Investment Company Rules

If Ballard were to constitute a “Passive Foreign Investment Company” or “PFIC” for any year during a U.S. holder’s holding period, then certain potentially adverse rules would affect the U.S. federal income tax consequences to a U.S. holder resulting from the acquisition, ownership and disposition of Ballard common shares. Ballard believes that it was not a PFIC during the prior tax year, and based on current business plans and financial expectations, Ballard expects that it will not be a PFIC for the current tax year and does not expect to be a PFIC for the foreseeable future.

However, PFIC classification is fundamentally factual in nature, generally cannot be determined until the close of the tax year in question, and is determined annually. Additionally, the analysis depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. Consequently, there can be no assurance that Ballard has never been, is not, and will not become a PFIC for any tax year during which U.S. holders hold Ballard common shares.

In addition, in any year in which Ballard is classified as a PFIC, such holder will be required to file an annual report with the IRS containing such information as Treasury regulations and/or other IRS guidance may require. In addition to penalties, a failure to satisfy such reporting requirements may result in an extension of the time period during which the IRS can assess tax. U.S. holders should consult their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file a IRS Form 8621.

Ballard will be a PFIC under Section 1297 of the Code if, for a tax year, (a) 75% or more of the gross income of Ballard for such tax year is passive income (the “income test”) or (b) 50% or more of the value of Ballard’s assets either produce passive income or are held for the production of passive income (the “asset test”), based on the quarterly average of the fair market value of such assets. “Gross income” generally includes all sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and “passive income” generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions.

In addition, for purposes of the PFIC income test and asset test described above, if Ballard owns, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, Ballard will be treated as if it (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and asset test described above and assuming certain other requirements are met, “passive income” does not include certain interest, dividends, rents, or royalties that are received or accrued by Ballard from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income and certain other requirements are satisfied.

Under certain attribution rules, if Ballard is a PFIC, U.S. holders will be deemed to own their proportionate share of any subsidiary of Ballard which is also a PFIC (a ‘‘Subsidiary PFIC’’), and will be subject to U.S. federal income tax on (i) a distribution on the shares of a Subsidiary PFIC or (ii) a disposition of shares of a Subsidiary PFIC, both as if the holder directly held the shares of such Subsidiary PFIC.

If Ballard were a PFIC in any tax year and a U.S. holder held Ballard common shares, such holder generally would be subject to special rules under Section 1291 of the Code with respect to “excess distributions” made by Ballard on the Ballard common shares and with respect to gain from the disposition of Ballard common shares. An “excess distribution” generally is defined as the excess of distributions with respect to the Ballard common shares received

48

Table of Contents

by a U.S. holder in any tax year over 125% of the average annual distributions such U.S. holder has received from Ballard during the shorter of the three preceding tax years, or such U.S. holder’s holding period for the Ballard common shares, as applicable. Generally, a U.S. holder would be required to allocate any excess distribution or gain from the disposition of the Ballard common shares ratably over its holding period for the Ballard common shares. Such amounts allocated to the year of the disposition or excess distribution would be taxed as ordinary income, and amounts allocated to prior tax years would be taxed as ordinary income at the highest tax rate in effect for each such year and an interest charge at a rate applicable to underpayments of tax would apply.

While there are U.S. federal income tax elections that sometimes can be made to mitigate these adverse tax consequences (including, without limitation, the “QEF Election” under Section 1295 of the Code and the “Mark-to-Market Election” under Section 1296 of the Code), such elections are available in limited circumstances and must be made in a timely manner.

U.S. holders should be aware that, for each tax year, if any, that Ballard is a PFIC, Ballard can provide no assurances that it will satisfy the record keeping requirements of a PFIC, or that it will make available to U.S. holders the information such U.S. holders require to make a QEF Election with respect to Ballard or any Subsidiary PFIC. U.S. holders should consult their own tax advisors regarding the potential application of the PFIC rules to the ownership and disposition of Ballard common shares, and the availability of certain U.S. tax elections under the PFIC rules.

Controlled Foreign Corporation Rules

If Ballard were to constitute a “Controlled Foreign Corporation” or “CFC” for any year during a U.S. holder’s holding period, then certain potentially adverse tax rules could affect a “United States shareholder” of Ballard, defined generally as a United States person who owns (within the meaning of Section 958(a) of the Code) or is considered as owning, by applying the rules of ownership of Section 958(b) of the Code, 10% or more of the combined voting power of all classes of stock of Ballard entitled to vote. In general, a foreign corporation is a CFC if more than fifty percent of (i) the total combined voting power of all classes of stock of such corporation entitled to vote, or (ii) the total value of such corporation is owned or is considered owned by “United States shareholders” on any day during the taxable year of the Corporation.

It is not expected that Ballard will be a CFC for U.S. tax purposes following the Merger. It is possible, however, that the ownership of Ballard stock could change over time and that Ballard could at some point become a CFC. Each U.S. holder should consult its own tax advisor concerning any potential application of the CFC rules.

Additional Considerations

Additional Tax on Passive Income

Individuals, estates and certain trusts whose income exceeds certain thresholds will be required to pay a 3.8% Medicare surtax on “net investment income” including, among other things, dividends and net gain from disposition of property (other than property held in certain trades or businesses). U.S. holders should consult with their own tax advisors regarding the effect, if any, of this tax on their ownership and disposition of Ballard common shares.

Receipt of Foreign Currency

The amount of any distribution paid to a U.S. holder in foreign currency, or on the sale, exchange or other taxable disposition of Ballard common shares, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). If the foreign currency received is not converted into U.S. dollars on the date of receipt, a U.S. holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. holder who receives payment in foreign currency and engages in a subsequent conversion or other disposition of the foreign currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Different rules apply to U.S. holders who use the accrual method. Each U.S. holder should consult its own U.S. tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

Foreign Tax Credit

Subject to the PFIC rules discussed above, a U.S. holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the Ballard common shares generally will be entitled, at the election of such U.S. holder, to receive either a deduction or a credit for such Canadian income tax paid. Generally, a credit will reduce a U.S. holder’s U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. holder’s income subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. holder during a year.

Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a U.S. holder’s U.S. federal income tax liability that such U.S. holder’s “foreign source” taxable income bears to such U.S. holder’s worldwide taxable income. In applying this limitation, a U.S. holder’s various items of income and deduction must be classified, under complex rules, as either “foreign source” or “U.S. source.” Generally, dividends paid by a foreign corporation should be treated as foreign source for this purpose, and

49

Table of Contents

gains recognized on the sale of stock of a foreign corporation by a U.S. holder should be treated as U.S. source for this purpose, except as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, the amount of a distribution with respect to the Ballard common shares that is treated as a “dividend” may be lower for U.S. federal income tax purposes than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a U.S. holder. In addition, this limitation is calculated separately with respect to specific categories of income. The foreign tax credit rules are complex, and each U.S. holder should consult its own U.S. tax advisor regarding the foreign tax credit rules.

Backup Withholding and Information Reporting

Under U.S. federal income tax law and Treasury regulations, certain categories of U.S. holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, U.S. return disclosure obligations (and related penalties) are imposed on U.S. holders that hold certain specified foreign financial assets in excess of certain threshold amounts. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign entity. U.S. holders may be subject to these reporting requirements unless their Ballard common shares are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. holders should consult with their own tax advisors regarding the requirements of filing information returns, including the requirement to file an IRS Form 8938.

Payments made within the U.S. or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of, Ballard common shares will generally be subject to information reporting and backup withholding tax (currently at the rate of 28%), if a U.S. holder (a) fails to furnish such U.S. holder’s correct U.S. taxpayer identification number (generally on IRS Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that such U.S. holder has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. holder that it is subject to backup withholding tax. However, certain exempt persons generally are excluded from these information reporting and backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. holder’s U.S. federal income tax liability, if any, or will be refunded, if such U.S. holder furnishes required information to the IRS in a timely manner.

The discussion of reporting requirements set forth above is not intended to constitute an exhaustive description of all reporting requirements that may apply to a U.S. holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax, and under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. Each U.S. holder should consult its own tax advisor regarding the information reporting and backup withholding rules.

Material Canadian Federal Income Tax Consequences

The following is a general summary of the material Canadian federal income tax considerations under the Tax Act generally applicable to a holder who, at all relevant times, for purposes of the Tax Act: (i) is not, and is not deemed to be, resident in Canada; (ii) does not use or hold the Ballard common shares in connection with carrying on a business in Canada; (iii) acquires Ballard common shares as beneficial owner in connection with the Merger; (iv) holds such common shares as capital property; (v) deals at arm’s length with Ballard; and who (vi) is not affiliated with Ballard (a “Non-Resident Holder”). This summary does not apply to a holder that is, or is deemed to be, resident in Canada or a Non-Resident Holder that carries on, or is deemed to carry on, an insurance business in Canada and elsewhere, and such holders should consult their own tax advisors.

The Ballard common shares will generally be considered capital property to a Non-Resident Holder unless either (i) the Non-Resident Holder holds the common shares in the course of carrying on a business of buying and selling securities or (ii) the Non-Resident Holder has acquired the common shares in a transaction or transactions considered to be an adventure in the nature of trade.

50

Table of Contents

This summary is not applicable to a Non-Resident Holder: (a) that is a “financial institution” as defined in the Tax Act for purposes of the mark-to-market rules; (b) an interest in which would be a “tax shelter investment” as defined in the Tax Act; (c) that is a “specified financial institution” as defined in the Tax Act; (d) whose functional currency for purposes of the Tax Act is the currency of a country other than Canada; or (e) that has entered (or will enter) into, with respect to the Ballard common shares, a “derivative forward agreement” as defined in the Tax Act. Any Non-Resident Holder to which this summary does not apply should consult its own tax advisor.

This summary is based on the current provisions of the Tax Act and the regulations thereunder (the “Regulations”) in force as of the date hereof, an understanding of the current administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”) publicly available prior to the date hereof, and all specific proposals to amend the Tax Act and Regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Proposed Amendments”). No assurances can be given that the Proposed Amendments will be enacted or will be enacted as proposed. Other than the Proposed Amendments, this summary does not take into account or anticipate any changes in law or the administration policies or assessing practice of CRA, whether by judicial, legislative, governmental or administrative decision or action, nor does it take into account provincial, territorial or foreign tax legislation or considerations, which may differ significantly from those discussed herein.

For purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of the Ballard common shares, including interest, dividends, adjusted cost base and proceeds of disposition, must be converted into Canadian dollars based on the relevant exchange rate (as determined in accordance with the Tax Act) applicable on the date the particular amount arose.

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder and no representations with respect to the income tax consequences to any particular Non-Resident Holder are made. This summary is not exhaustive of all Canadian federal income tax considerations. Accordingly, prospective investors in the Ballard common shares should consult their own tax advisors with respect to their own particular circumstances.

Disposition of Ballard Common Shares

A Non-Resident Holder will not be subject to tax under the Tax Act in respect of any capital gain realized by such Non-Resident Holder on a disposition of the common shares, unless such shares constitute “taxable Canadian property” (as defined in the Tax Act) of the Non-Resident Holder at the time of disposition and the Non-Resident Holder is not entitled to relief under an applicable income tax treaty or convention.

As long as the Ballard common shares are then listed on a designated stock exchange (which currently includes the TSX and the NASDAQ), the common shares generally will not constitute taxable Canadian property of a Non-Resident Holder, unless (a) at any time during the 60 month period immediately preceding the disposition or deemed disposition of the common shares: (i) 25% or more of the issued shares of any class of the capital stock of Ballard was owned by, or belonged to, one or any combination of the Non-Resident Holder and persons with whom the Non-Resident Holder did not deal at arm’s length (within the meaning of the Tax Act); and (ii) more than 50% of the fair market value of a Ballard common share was derived directly or indirectly from one or any combination of: (A) real or immovable property situated in Canada; (B) Canadian resource property (as defined in the Tax Act); (C) timber resource property (as defined in the Tax Act), or (D) options in respect of, or interests in, or for civil law rights in, property described in any of (A) through (C) above, whether or not such property exists; or (b) the Ballard common shares are otherwise deemed under the Tax Act to be taxable Canadian property.

If the Ballard common shares are taxable Canadian property to a Non-Resident Holder, any capital gain realized on the disposition or deemed disposition of such common shares may not be subject to Canadian federal income tax pursuant to the terms of an applicable income tax treaty or convention between Canada and the country of residence of a Non-Resident Holder.

Non-Resident Holders whose common shares are taxable Canadian property should consult their own advisors.

Table of Contents

Dividends

Under the Tax Act, dividends on common shares paid or credited to a Non-Resident Holder will be subject to Canadian withholding tax at the rate of 25% of the gross amount of the dividends, subject to any reduction in the rate of withholding to which the Non-Resident Holder is entitled under any applicable income tax treaty or convention between Canada and the country in which the Non-Resident Holder is resident. For example, where a Non-Resident Holder is a resident of the United States, is fully entitled to the benefits under the Canada-United States Income Tax Convention (1980) and is the beneficial owner of the dividend, the applicable rate of Canadian withholding tax is generally reduced to 15% of the amount of such dividend.

Appraisal Rights of Holders of Protonex Common Stock

In connection with the Merger, record holders of Protonex common stock who comply with the procedures summarized below will be entitled to appraisal rights if the Merger is completed. Under Section 262 of the General Corporation Law of the State of Delaware (which we refer to as Section 262), as a result of completion of the Merger, holders of shares of Protonex common stock with respect to which appraisal rights are properly demanded and perfected and not withdrawn or lost are entitled, in lieu of receiving the Merger consideration, to have the “fair value” of their shares at the effective time of the Merger (exclusive of any element of value arising from the accomplishment or expectation of the Merger) judicially determined and paid to them in cash by complying with the provisions of Section 262. Protonex is required to send a notice to that effect to each stockholder not less than 20 days prior to the special meeting. This proxy statement/prospectus constitutes that notice to you.

The following is a brief summary of Section 262, which sets forth the procedures for demanding statutory appraisal rights. This summary is qualified in its entirety by reference to Section 262, a copy of the text of which is attached to this proxy statement/prospectus as Appendix C.

Stockholders of record who desire to exercise their appraisal rights must satisfy all of the following conditions:

· A stockholder who desires to exercise appraisal rights must (a) not vote in favor of the Merger and (b) deliver a written demand for appraisal of the stockholder shares to the corporate secretary of Protonex before the vote on the Merger at the special meeting.

· A demand for appraisal must be executed by or for the stockholder of record, fully and correctly, as the stockholder’s name appears on the certificates representing shares. If shares are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, such demand must be executed by the fiduciary. If shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand must be executed by all joint owners. An authorized agent, including an agent of two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner and expressly disclose that, in exercising the demand, the agent is acting as agent for the record owner. In addition, the stockholder must continuously hold the shares of record from the date of making the demand through the effective time of the Merger.

· A record owner, such as a broker, who holds shares as a nominee for others may exercise appraisal rights with respect to the shares held for all or less than all beneficial owners of shares as to which the holder is the record owner. In that case, the written demand must set forth the number of shares covered by the demand. Where the number of shares is not expressly stated, the demand will be presumed to cover all shares outstanding in the name of the record owner.

· Beneficial owners who are not record owners and who intend to exercise appraisal rights should instruct the record owner to comply strictly with the statutory requirements with respect to the exercise of appraisal rights before the vote on the adoption of the Merger Agreement at the special meeting. A holder of shares held in “street name” who desires appraisal rights with respect to those shares must take such actions as may be necessary to ensure that a timely and proper demand for

52

Table of Contents

appraisal is made by the record owner of the shares. Shares held through brokerage firms, banks and other financial institutions are frequently deposited with and held of record in the name of a nominee of a central security depositary. Any holder of shares desiring appraisal rights with respect to such shares who held such shares through a brokerage firm, bank or other financial institution is responsible for ensuring that the demand for appraisal is made by the record holder. The stockholder should instruct such firm, bank or institution that the demand for appraisal must be made by the record holder of the shares, which might be the nominee of a central security depositary if the shares have been so deposited.

As required by Section 262, a demand for appraisal must be in writing and must reasonably inform Protonex of the identity of the record holder (which might be a nominee as described above) and of such holder’s intention to seek appraisal of such shares.

Stockholders of record who elect to demand appraisal of their shares must mail or deliver their written demand to: Protonex Technology Corporation, 153 Northboro Road, Southborough, Massachusetts 01772-1034, Attention: Corporate Secretary. The written demand for appraisal should specify the stockholder’s name and mailing address, the number of shares owned, and that the stockholder is demanding appraisal of his, her or its shares. The written demand must be received by Protonex prior to the special meeting. Neither voting (in person or by proxy) against, abstaining from voting on or failing to vote on the proposal to adopt the Merger Agreement will alone suffice to constitute a written demand for appraisal within the meaning of Section 262. In addition, the stockholder must not vote its shares of common stock in favor of adoption of the Merger Agreement. Because a proxy that does not contain voting instructions will, unless revoked, be voted in favor of adoption of the Merger Agreement, a stockholder who votes by proxy and who wishes to exercise appraisal rights must vote against the Merger Agreement or abstain from voting on the Merger Agreement.

Within 120 days after the effective time of the Merger, either the surviving corporation in the Merger or any stockholder who has timely and properly demanded appraisal of such stockholder’s shares and who has complied with the requirements of Section 262 and is otherwise entitled to appraisal rights may file a petition in the Delaware Court of Chancery demanding a determination of the fair value of the shares of all stockholders who have properly demanded appraisal. If a petition for an appraisal is timely filed, after a hearing on such petition, the Delaware Court of Chancery will determine which stockholders are entitled to appraisal rights and thereafter will appraise the shares owned by those stockholders, determining the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with interest to be paid, if any, upon the amount determined to be the fair value. In determining fair value, the Delaware Court of Chancery is to take into account all relevant factors. In Weinberger v. UOP, Inc., et al., the Delaware Supreme Court discussed the considerations that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company.” The Delaware Supreme Court stated that in making this determination of fair value the court must consider “market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts which were known or which could be ascertained as of the date of Merger which throw any light on future prospects of the merged corporation.” The Delaware Supreme Court construed Section 262 to mean that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the Merger and not the product of speculation, may be considered.” However, the Delaware Supreme Court noted that Section 262 provides that fair value is to be determined “exclusive of any element of value arising from the accomplishment or expectation of the merger.”

Stockholders considering seeking appraisal should bear in mind that the fair value of their shares determined under Section 262 could be more than, the same as, or less than the Merger consideration they are entitled to receive pursuant to the Merger Agreement if they do not seek appraisal of their shares, and that opinions of investment banking firms as to the fairness from a financial point of view of the consideration payable in a merger are not opinions as to fair value under Section 262.

The cost of the appraisal proceeding may be determined by the Delaware Court of Chancery and charged upon the parties as the Delaware Court of Chancery deems equitable in the circumstances. Upon application of a stockholder seeking appraisal rights, the Delaware Court of Chancery may order that all or a portion of the expenses

53

Table of Contents

incurred by such stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts, be charged pro rata against the value of all shares entitled to appraisal. In the absence of such a determination of assessment, each party bears its own expenses.

Except as explained in the last sentence of this paragraph, at any time within 60 days after the effective time of the Merger, any stockholder who has demanded appraisal shall have the right to withdraw such stockholder’s demand for appraisal and to accept the Ballard common shares to which the stockholder is entitled pursuant to the Merger. After this period, the stockholder may withdraw such stockholder’s demand for appraisal only with the consent of the surviving corporation in the Merger. If no petition for appraisal is filed with the Delaware Court of Chancery within 120 days after the effective time of the Merger, stockholders’ rights to appraisal shall cease and all stockholders shall be entitled only to receive the Ballard common shares as provided for in the Merger Agreement. Inasmuch as the parties to the Merger Agreement have no obligation to file such a petition, and have no present intention to do so, any stockholder who desires that such petition be filed is advised to file it on a timely basis. No petition timely filed in the Delaware Court of Chancery demanding appraisal shall be dismissed as to any stockholders without the approval of the Delaware Court of Chancery, and that approval may be conditioned upon such terms as the Delaware Court of Chancery deems just.

The foregoing is a brief summary of Section 262 that sets forth the procedures for demanding statutory appraisal rights. This summary is qualified in its entirety by reference to Section 262, a copy of the text of which is attached hereto as Appendix C. Failure to comply with all the procedures set forth in Section 262 will result in the loss of a stockholder’s statutory appraisal rights.

Restrictions on Sales of Common Shares by Certain Affiliates

The Ballard common shares to be issued in connection with the Merger will be freely transferable under the Securities Act, except for shares issued to any Protonex stockholder who may be deemed to be an “affiliate” of Protonex immediately prior to the Merger or an affiliate of Ballard following the Merger for purposes of U.S. securities laws.

Persons who may be deemed to be affiliates of Protonex or Ballard may not sell any of the Ballard common shares received by them in connection with the Merger except pursuant to:

· an effective registration statement under the Securities Act covering the resale of those shares;

· an exemption under paragraph (d) of Rule 145 under the Securities Act; or

· any other applicable exemption under the Securities Act.

The sale of Ballard common shares received pursuant to the Merger will be free from restriction under applicable Canadian securities legislation on the first trade of such Ballard common shares provided that (1) Ballard is and has been a reporting issuer in a jurisdiction of Canada for the four months immediately preceding the sale; (2) such sale is not a control distribution, (3) no unusual effort is made to prepare the market or to create a demand for the Ballard common shares subject to such sale, (4) no extraordinary commission or consideration is paid to a person or company in respect of such sale and (5) if the selling security holder is an insider or officer of Ballard, the selling security holder has no reasonable grounds to believe that Ballard is in default of Canadian securities legislation.

Directors and Management of Ballard Following the Merger

The directors and officers of Ballard are anticipated to remain the same after the Merger.

Regulatory Approvals Required for the Merger

Other than (i) the requirement that this proxy statement/prospectus be filed with the SEC; (ii) the requirement that the SEC declare the registration statement of which this proxy statement/prospectus is a part effective and that we distribute this proxy statement/prospectus as required under applicable securities laws; (iii) the requirement that we make certain other filings under the Exchange Act, applicable Canadian securities laws and NASDAQ and TSX rules and (iv) the requirement to notify the Directorate of Defense Trade Controls of the U.S. State Department pursuant to Section 122.4 of the International Traffic in Arms Regulations, we are not aware of any material U.S. federal, state or foreign regulatory requirements or approvals that must

54

Table of Contents

be complied with or obtained in connection with the Merger. We cannot predict whether we will obtain all required regulatory approvals to complete the Merger, or whether any approvals will include conditions that would be detrimental to us or the combined company.

Ballard’s Status as a Foreign Private Issuer under the U.S. Securities Exchange Act of 1934

Ballard is considered a “foreign private issuer” under the rules of the SEC and is subject to the reporting requirements under the Exchange Act applicable to foreign private issuers. Ballard is required to file its annual report on Form 40-F with the SEC at the time it files its annual information form with the applicable Canadian securities regulatory authorities (or, if applicable, a Form 20-F within four months of its fiscal year end). In addition, Ballard must furnish current reports on Form 6-K to the SEC regarding certain information required to be publicly disclosed by Ballard in Canada or filed with the TSX, or regarding information distributed or required to be distributed by Ballard to its stockholders.

Moreover, although Ballard is required to comply with Canadian disclosure requirements, in some circumstances Ballard is not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. Ballard is required to file financial statements in accordance with IFRS, and therefore does not file financial statements prepared in accordance with U.S. GAAP. Furthermore, Ballard is not required to comply with Regulation FD, which addresses certain restrictions on the selective disclosure of material information. In addition, among other matters, Ballard’s officers, directors and principal stockholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules under the Exchange Act with respect to their purchases and sales of Ballard common shares. If Ballard loses its status as a foreign private issuer, it will no longer be exempt from such rules and, among other things, will be required to file periodic reports and financial statements as if it were a United States domestic company. Ballard’s Canadian public filings are available at www.sedar.com, and its SEC filings are available on EDGAR at www.sec.gov. Insiders of Ballard are generally required to disclose their trading in Ballard shares within five days of the date of the trade and these trading activity reports can be accessed through the Internet at www.sedi.ca.

PRINCIPAL STOCKHOLDERS OF THE COMBINED COMPANY

The following table and the related notes present certain information with respect to the beneficial ownership of the combined company upon consummation of the Merger, by:

· each person expected to be a director or executive officer of the combined company;

· each person or group who is expected by the management of the combined company to become the beneficial owner of more than 5% of the common shares of the combined company upon the consummation of the Merger, and

· all persons expected to be directors or executive officers of the combined company as a group.

The percentage of beneficial ownership calculation assumes that the Merger closes on September 30, 2015 and is based on total outstanding common shares of 153,172,258 which is the sum of (i) 141,957,346 common shares outstanding as of August 11, 2015 and (ii) 11,214,912 shares that would be issued to the Protonex stockholders in the Merger based on a closing date of September 30, 2015, and which amount includes 628,732 shares placed in the escrow. The information below assumes: (i) that no options held by Protonex stockholders and no warrants to purchase shares of Protonex common stock are exercised upon any vesting of such securities at or immediately prior to the effective time of the Merger in accordance with the terms of the Merger Agreement or applicable award or warrant agreement, (iii) that no additional Ballard common shares or securities convertible into Ballard common shares are issued by Ballard subsequent to September 30, 2015 other than in connection with the Merger, and (iv) that each director’s and executive officer’s beneficial ownership of Ballard common shares does not change prior to consummation of the Merger.

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally provide that a person is the “beneficial owner” of securities if such person has or shares the power to vote or direct the voting of

55

Table of Contents

securities, or to dispose or direct the disposition of securities or has the right to acquire such powers within 60 days. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, common shares subject to options, warrants or rights held by that person that are currently exercisable or convertible or exercisable, convertible or issuable within 60 days of August 5, 2015, are deemed outstanding. Such shares, however, are not deemed outstanding for the purpose of computing the percentage ownership of any other person. The percentages in the table have been rounded to the nearest hundredth. Except as specifically indicated in the footnotes to this table, we believe that the persons identified in this table have sole voting and investment power with respect to all common shares shown as beneficially owned by them, subject to community property laws where applicable.

MERGER AGREEMENT

Below is a summary of the Merger Agreement, which is attached to this proxy statement/prospectus as Appendix A and is incorporated by reference into this document. You should read the Merger Agreement in addition to this summary, as the Merger Agreement, and not this summary, is the legal document which governs the Merger. Capitalized terms used in this section and not otherwise defined in this proxy statement/prospectus have the meanings ascribed to them in the Merger Agreement.

Cautionary Statement Concerning Representations and Warranties Contained in the Merger Agreement

You should not rely upon the representations and warranties contained in the Merger Agreement or the descriptions of such representations and warranties in this proxy statement/prospectus, as factual information about Ballard or Protonex. In reviewing the agreements included or incorporated by reference in this proxy statement/prospectus, it is important to note that they are included to provide investors and stockholders with information regarding their

56

Table of Contents

terms, and are not intended to provide any other factual or disclosure information about Ballard or Protonex or the other parties to the agreements. These representations and warranties have been made solely for the benefit of the other parties to the Merger Agreement, and were not intended to be and should not be relied upon by stockholders of Ballard or Protonex; should not be treated as categorical statements of fact, but rather as a way of allocating risk between the parties; have in some cases been qualified by disclosures that were made to the other party in connection with the negotiation of the Merger Agreement, which disclosure schedules are not reflected in the Merger Agreement or disclosed in this proxy statement/prospectus; may apply standards of materiality in a way that is different from what may be material to investors; and were made only as of the date of the Merger Agreement or such other date or dates as may be specified in the Merger Agreement and are subject to more recent developments.

Accordingly, these representations and warranties may not describe the actual state of affairs as of the date they were made or at any other time. Information about Ballard can be found elsewhere in this proxy statement/prospectus and in other public filings Ballard makes with the SEC and with Canadian securities administrators. Information about Protonex can be found elsewhere in this proxy statement/prospectus.

General

The boards of directors of both Ballard and Protonex have adopted and approved the Merger Agreement, which provides for the acquisition by Ballard of Protonex through the Merger. The Merger will result in Merger Sub, a Delaware corporation and wholly-owned subsidiary of Ballard, merging with and into Protonex, so that Protonex, as the surviving corporation, will become a wholly-owned subsidiary of Ballard. In exchange for their shares of Protonex’s common stock, the Protonex stockholders will receive Ballard common shares. Former Protonex stockholders will not have any equity ownership interest in the surviving corporation.

Conversion of Securities in the Merger

The aggregate Merger consideration (the “Aggregate Consideration”) is equal to approximately 11,214,912 Ballard common shares. Protonex stockholders will receive approximately 0.1562 Ballard common shares for every share of Protonex common stock owned (the “Per Share Common Consideration”), subject to the closing purchase price adjustment and any claims for indemnification under the Merger Agreement. The closing price of one share of Ballard common stock on the NASDAQ on August 10, 2015 was U.S. $1.33. As discussed in detail below, the aggregate number shares of Ballard common stock to be issued in connection with the Merger will vary depending on a number of factors, including the amount of the estimated Net Debt of Protonex at closing.

At the effective time of the Merger, each issued and outstanding share of Protonex common stock (other than any Dissenting Shares and Treasury Shares) will be cancelled and converted into the right to receive the Per Share Common Consideration, subject to adjustment. Each issued and outstanding share of Protonex common stock that is held in the treasury of Protonex or owned by Protonex, Ballard or Merger Sub will be automatically cancelled and will receive no consideration.

Each issued and outstanding share of the common stock of Merger Sub will be converted into and become one fully paid and nonassessable share of common stock of Protonex (the surviving corporation in the Merger).

For the purpose of calculating the Per Share Common Consideration, adjustments will be made to reflect the effect of any stock split, split-up, reverse stock split, dividend or distribution of securities convertible into Protonex common stock, Protonex preferred stock or Ballard common stock, reorganization, recapitalization, reclassification or other like change with respect to Protonex common stock, Protonex preferred stock or Ballard common stock having a record date occurring on or after the date of the Merger Agreement and prior to the effective time of the Merger.

The allocation of shares of Ballard common stock to be issued in the Merger among stockholders of Protonex will vary depending on a number of factors, including the amount of the Net Debt of Protonex at closing.

For purposes of the Merger Agreement, “Net Debt” means (i) all Long Term Liabilities minus (ii) all cash and cash equivalents of Protonex determined in accordance with U.S. GAAP plus (iii) all unpaid Protonex transactions expenses. “Long Term Liabilities” means all indebtedness (including the current portion thereof) and other long term liabilities of Protonex or any of its subsidiaries on a consolidated basis determined in accordance with U.S.

GAAP (including any such liabilities arising as a result of the consummation of the Merger and the transactions contemplated hereby).

Options and Warrants

In accordance with the Merger Agreement and Protonex’s 2003 Stock Incentive Plan and 2013 Stock Incentive Plan, holders of options to purchase Protonex common stock must exercise such options by the fifth business day prior to the date of the special meeting of Protonex stockholders, or their options will be cancelled. In addition, under the Merger Agreement, Protonex has agreed to cause all outstanding warrants to purchase Protonex common stock to be exercised or terminated prior to the effective time of the Merger. Ballard will not assume any Protonex options, warrants or other derivative securities in connection with the Merger, and you will receive no Merger consideration in exchange for such securities. Any Protonex options or warrants duly exercised for shares of Protonex common stock prior to the effective time of the Merger will be entitled to the Merger consideration for their shares of common stock held at the effective time.

Closing Consideration Schedule

Protonex has agreed to deliver to Ballard, no later than one business day prior to the closing date, a “Closing Consideration Schedule” setting forth, as of closing, all Protonex stockholders and their respective addresses, the number of shares of Protonex common stock held (including the respective certificate numbers), the pro rata portion and the pro rata allocation of the escrowed shares applicable to each Supporting Stockholder and the number of Ballard common shares to be issued to each such Protonex stockholder.

Fractional Shares

No fractional shares of Ballard common stock will be issued in connection with the Merger and no dividends or other distributions with respect to the Ballard common shares will be payable on or with respect to any fractional share.

Escrow of Consideration; Escrow Account

At the closing, Ballard, the stockholder representative and U.S. Bank, National Association, the Escrow Agent, will enter into the escrow agreement pursuant to which Ballard will cause to be deposited approximately 628,732 Ballard common shares in an escrow account. These common shares will be used to cover indemnification claims by Ballard pursuant to the terms of the Merger Agreement, which shares will be released 12 months after the closing of the Merger, subject to any then pending claims. For purposes of satisfying claims for indemnification, all Ballard common shares in the escrow account will be deemed to have a value equal to U.S. $2.28 (the “Price Per Share”), as may be adjusted pursuant to the terms of the Merger Agreement. The Supporting Stockholders who contribute a portion of the Aggregate Consideration that they are entitled to receive under the terms of the Merger Agreement to the escrow account will be the owners of the shares deposited in the escrow account and will be entitled to vote all escrowed shares on their own behalf.

In the event of any claim for indemnification under the Merger Agreement, the Ballard Indemnitees (as defined below) will be entitled to recover any damages from the escrow account. Pursuant to the Merger Agreement, within five days following the one-year anniversary of the closing date, Ballard and stockholder representative will instruct the Escrow Agent to deliver to each the applicable Supporting Stockholder his, her or its pro rata allocation of (i) Ballard common shares remaining in the escrow account minus (ii) (a) pending claims determined as of the one-year anniversary, divided by (b) the Price Per Share. See “Merger Agreement—Survival; Indemnification” below at page 60.

Stockholder Representative

By executing the Merger Agreement and upon executing a written consent, voting in favor of the Merger or executing a letter of transmittal, the stockholders of Protonex will appoint Edward J. Stewart as the stockholder representative for purposes of taking certain actions and giving certain consents on behalf of any Protonex stockholder relating to the Merger Agreement and the escrow agreement.

Table of Contents

Stockholder Representative Expense Fund

Upon the closing, Ballard will wire to the stockholder representative U.S. $25,000 to serve as the expense fund to pay and reimburse the stockholder representative for any third party expenses incurred in connection with the stockholder representative performing his, her or its duties pursuant to the Merger Agreement or the escrow agreement. In the event the stockholder representative’s expenses exceed, or are reasonably expected to exceed U.S. $25,000, Ballard will wire the stockholder representative additional funds; provided that Ballard will be entitled to recover any such additional funds from the escrow account.

Closing and Effectiveness of the Merger

The closing of the Merger is to take place on the fifth business day following the satisfaction or, to the extent permitted under the Merger Agreement and by applicable law, waiver of all conditions to the obligations of the parties set forth in the Merger Agreement and described below (other than such conditions as may, by their terms, only be satisfied at the closing or on the closing date, but subject to such satisfaction or waiver thereof). See “Merger Agreement—Conditions to the Consummation of the Merger” on page 64.

Exchange of Protonex Stock Certificates for the Merger Consideration

The Merger Agreement provides that the surviving corporation will cause Computershare Investor Services Inc., the exchange agent to be appointed by Ballard in connection with the Merger, to mail within three business days following the effective time, to each record holder of Protonex common stock, a letter of transmittal and instructions for surrendering and exchanging the record holder’s Protonex share certificates for Ballard common stock. Upon surrender of a Protonex share certificate for exchange to the exchange agent, together with a duly completed and validly executed letter of transmittal, and such other documents as the exchange agent may reasonably require, the record holder of the Protonex certificate will be entitled to receive the number of uncertificated shares of Ballard common stock entitled to receive under the Merger Agreement and as set forth on the Closing Consideration Schedule. No interest will be paid on the Merger consideration payable in connection with the Merger Agreement.

If any Protonex share certificate has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or destroyed and, if required by Ballard or the exchange agent, the delivery by such person of an indemnification agreement acceptable to Ballard and the exchange agent, or if required by the exchange agent, posting by such person of a bond in such amount as Ballard or the exchange agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such certificate, the exchange agent will deliver in exchange for such lost, stolen or destroyed certificate the consideration payable in respect thereof.

Ballard, the surviving corporation, the exchange agent and the Escrow Agent are entitled to deduct and withhold from consideration otherwise payable under the Merger Agreement to any Protonex stockholder or other person, amounts needed to be withheld with respect to making any such payment under the Code or any provision of state, local or foreign tax law.

Appraisal Rights

Any shares of Protonex common stock that are issued and outstanding immediately prior to the effective time of the Merger and that have not approved the Merger via an affirmative vote or written consent (or which the holder has not effectively withdrawn or lost such holder’s appraisal rights), and with respect to which a demand for appraisal has been properly made in accordance with the DGCL, will not be converted into or represent a right to receive the Merger consideration otherwise payable with respect to such shares of Protonex common stock. If any holder of dissenting shares has effectively withdrawn or loses its appraisal rights, such shares will receive the consideration set forth in the Merger Agreement. Protonex has agreed to give Ballard (i) prompt notice of any written demand for appraisal received and (ii) the opportunity to participate in all negotiations and proceedings with respect to any demands made prior to closing. Communications between Protonex and any Protonex stockholder will require the consent of Ballard. Any excess dissenting share payments will be recoverable by Ballard. For purposes of distributing any portion of escrowed shares, no dissenting stockholder will participate in the escrow and any payment by Ballard that would have been required to be made to such holder of dissenting shares will be retained by Ballard.

· by Protonex, if at any time prior to obtaining the approval of the Protonex stockholders, the Company has received an acquisition proposal that the Protonex board of directors has determined to be a superior proposal (as defined in the Merger Agreement).

Effect of Termination

If the Merger is terminated as described in the section entitled “Merger Agreement—Termination of the Merger Agreement” above, the Merger Agreement will be void, except that for certain designated provisions of the Merger Agreement, and each party will redeliver all documents, work papers and other material of any other party relating to the transactions contemplated hereby, and no party shall have any liability to any other party to the Merger Agreement, provided that nothing shall limit or restrict the availability of specific performance or other injunctive relief to the extent that specific performance or such other relief would otherwise be available to a party.

Termination Amount

If the Merger Agreement is terminated by Protonex pursuant to the last bullet in the section entitled “Merger Agreement—Termination of the Merger Agreement” above, then Ballard is required to pay Protonex a nonrefundable fee in the amount in cash equal to U.S. $200,000 (the “Termination Amount”). Ballard is required to pay the Termination Amount to Protonex, by wire transfer of immediately available funds to an account designated by Protonex, within two business days after the date of such termination unless, solely in the case of a termination of the Merger Agreement pursuant to the last bullet in the section entitled “Merger Agreement—Termination of the Merger Agreement” above as a result of willful and intentional breach by Ballard or Merger Sub, Protonex notifies Ballard in writing at the time of termination that it will pursue a remedy other than the Termination Amount (in which case Ballard will have no obligation to pay the Termination Amount).

If the Merger Agreement is terminated by Ballard pursuant to the either the second or third bullet in the section entitled “Merger Agreement—Termination of the Merger Agreement” above, then Ballard is required to pay Protonex a nonrefundable fee in the amount in cash equal to the Termination Amount. Protonex is required to pay the Termination Amount to Ballard, by wire transfer of immediately available funds to an account designated by Ballard, within two business days after the date of such termination.

If the Merger Agreement is terminated by Protonex pursuant to the last bullet in the section entitled “Merger Agreement—Termination of the Merger Agreement” above, then Protonex is required to pay Ballard, by wire transfer of immediately available funds, at or prior to the date of termination, a termination fee of $1,500,000, plus Ballard’s fees and expenses in connection with the negotiation, preparation and performance of the Merger Agreement.

Amendment

The Merger Agreement may not be amended or modified except in an instrument in writing signed by the stockholder representative and Ballard. No amendment, supplement, modification or waiver of the Merger Agreement will be binding unless executed in writing by the party to be bound thereby.

ANCILLARY AGREEMENTS

Support Agreement

The following description of certain material provisions of the support agreements is intended to be a summary only. This summary is qualified in its entirety by the full text of the form of the support agreements that is attached hereto as Appendix B and incorporated by reference herein.

Concurrently with the execution of the Merger Agreement, certain directors, executive officers, certain major stockholders and their affiliates each executed a support agreement with Ballard pursuant to which they have agreed to vote “FOR” the adoption and approval of the Merger Agreement and the Merger. As of the Protonex record date, these Supporting Stockholders held approximately 56% of the outstanding shares of Protonex common stock. Collectively, the support agreements provide for the vote of a sufficient number of shares of Protonex to adopt and

68

Table of Contents

approve the Merger Agreement and the Merger under applicable Delaware law and Protonex’s organizational documents.

All of the Supporting Stockholders agreed not to transfer any of their respective shares of Protonex prior to the closing of the Merger and have further agreed that any additional shares of Protonex acquired by such stockholders are also subject to the terms of the support agreements.

In addition, pursuant to the terms of the support agreement each of the signing stockholders of Protonex have made certain additional covenants, including the following:

· Confidentiality. All of the Protonex stockholders that signed the support agreements agreed not to, subject to certain exceptions, disclose the confidential and proprietary information of Protonex that any such stockholders may have in their possession.

· Public Announcements. All of the Protonex stockholders that signed the support agreements agreed not to, subject to certain exceptions, make any press release or other public disclosure with respect to the Merger Agreement, the support agreements and the Merger contemplated by such agreements.

· Lock-Up. All of the Protonex stockholders that signed the support agreements agreed that the Ballard common shares to be received by such stockholders in the Merger are all subject to lock up restrictions, which lock up restrictions will lapse with respect to one-half of such stockholder’s Ballard common shares received in the Merger at the six and 12 month anniversaries of the closing date. These restrictions prohibit the offer, sale, contracting to sell, pledge, grant of any option to purchase, making of any short sale or other disposition of any Ballard common shares during the lock-up period.

· Release. All of the Protonex stockholders that signed the support agreements agreed to release Ballard, Merger Sub, Protonex and their respective affiliates, subsidiaries, officers, directors, stockholders, partners, members, agents, successors and permitted assigns from certain claims that such stockholders may have against such parties. The release did not extend to certain claims, including those arising out of the Merger Agreement or with respect to such stockholder’s status as a current or former employee of the consultant of Protonex for certain matters.

Outstanding Protonex Shares and Required Vote

As of the Protonex record date, the outstanding voting securities of Protonex consist of (A) 64,978,500 shares of Protonex common stock, (B) no shares of Protonex preferred stock, (C) options to purchase 12,912,669 shares of Protonex common stock and (D) warrants to purchase 1,803,991 shares of Protonex common stock. The affirmative vote, at a duly called and held meeting of stockholders of Protonex of the holders of at least a majority of the outstanding shares of Protonex common stock, entitled to vote upon the Merger Agreement and the transactions contemplated by the Merger Agreement, is necessary to adopt and approve the Merger Agreement and the Merger.

As of the date of this proxy statement/prospectus, stockholders of Protonex representing approximately 56% of Protonex’s outstanding common stock have entered into support agreements with Ballard. Consequently, the support agreements collectively provide for the vote of a sufficient number of shares of Protonex to approve and adopt the Merger Agreement and the Merger under the DGCL and Protonex’s organizational documents.

Escrow Agreement

At the closing, Ballard, the stockholder representative and U.S. Bank, National Association, the Escrow Agent, will enter into the escrow agreement pursuant to which Ballard will cause to be deposited approximately 628,732 Ballard common shares payable to Supporting Stockholders in an escrow account. These common shares will be used to cover indemnification claims by Ballard pursuant to the terms of the Merger Agreement, which shares will be released 12 months after the closing of the Merger, subject to any then pending claims. For purposes of satisfying claims for indemnification, all Ballard common shares in the escrow account will be deemed to have a value equal to the Price Per Share, as may be adjusted pursuant to the terms of the Merger Agreement. The Supporting Stockholders who contribute a portion of the Aggregate Consideration that they are entitled to receive under the

69

Table of Contents

terms of the Merger Agreement to the escrow account will be the owners of the shares deposited in the escrow account and will be entitled to vote all escrowed shares on their own behalf.

In the event of any claim for indemnification under the Merger Agreement, the Ballard Indemnitees will be entitled to recover any damages from the escrow account. Pursuant to the Merger Agreement, within five days following the one-year anniversary of the closing date, Ballard and stockholder representative will instruct the Escrow Agent to deliver to each the applicable Supporting Stockholder his, her or its pro rata allocation of (i) Ballard common shares remaining in the escrow account minus (ii) (a) pending claims determined as of the one-year anniversary, divided by (b) the Price Per Share.

Commitment Letter

On August 6, 2015, Ballard committed to provide Protonex with a U.S. $500,000 bridge loan if Protonex requests the bridge loan in writing by August 21, 2015. Protonex currently anticipates requesting the bridge loan. If requested and made, the bridge loan will be payable upon and subject to the terms and conditions set forth in a demand promissory note. Under the terms of the note, interest would accrue at the rate of 6% per annum, compounding annually. On or after the date that is six months from the date of the note, the note will be due and payable upon Ballard’s demand; provided that if Ballard does not demand payment prior to the date that is two years from the date of the note (the “Final Maturity Date”), the outstanding principal amount of the note, together with all accrued and unpaid interest thereon, shall be payable on the Final Maturity Date without any demand for such repayment. The principal amount outstanding under the note may be prepaid by Protonex at any time in whole or in part without premium or penalty; provided that any prepayment must be accompanied by payment of accrued and unpaid interest on the amount prepaid. In addition, the note contains certain other covenants, restrictions and events of default that are customary for a note of this nature.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Overview

On June 29, 2015, Ballard Power Systems Inc., a Canadian corporation (“Ballard Power”), BPC SubCo Inc., a Delaware corporation and wholly-owned subsidiary of Ballard Power (“Merger Sub”), Protonex Technology Corporation, a Delaware corporation (“Protonex”) and Edward J. Stewart, as Protonex stockholder representative, entered into an Agreement and Plan of Merger (the “merger agreement”), pursuant to which Protonex will merge with and into Merger Sub (the “merger”), with Protonex as the surviving corporation. Following the merger, Protonex will be a wholly-owned subsidiary of Ballard Power. The transactions contemplated by the merger agreement have not yet been consummated.

The following unaudited pro forma condensed combined financial statements, referred to as the pro forma financial statements, present the combination of the historical consolidated financial statements of Ballard Power, prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”), and Protonex, prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”), adjusted to give effect to the combination. The pro forma financial statements have been prepared in accordance with applicable securities legislation.

The unaudited pro forma condensed combined statement of financial position, referred to as the pro forma statement of financial position, combines the unaudited historical condensed consolidated statement of financial position of Ballard Power as of June 30, 2015 and the unaudited historical condensed consolidated balance sheet of Protonex as of March 31, 2015, giving effect to the combination as if it had been consummated on June 30, 2015.

The unaudited pro forma condensed combined statement of income (loss) and other comprehensive income (loss) for the fiscal year ended December 31, 2014 assumes that the combination took place on January 1, 2014, the beginning of Ballard Power’s most recently completed fiscal year. Ballard Power’s audited consolidated statement of loss and other comprehensive loss for the fiscal year ended December 31, 2014 has been combined with Protonex’s audited consolidated statement of operations for the fiscal year ended September 30, 2014. The unaudited pro forma condensed combined statement of income (loss) and other comprehensive income (loss) for the six months ended June 30, 2015 assumes that the combination took place on January 1, 2014, the beginning of Ballard Power’s most recently completed fiscal year. Ballard Power’s unaudited consolidated statement of profit or loss and other comprehensive income (loss) for the six months ended June 30, 2015 has been combined with Protonex’s unaudited consolidated statement of operations for the six months ended March 31, 2015. The unaudited pro forma condensed combined statement of income (loss) and other comprehensive income (loss) for the fiscal year ended December 31, 2014 and the unaudited pro forma condensed combined statement of income (loss) and other comprehensive income (loss) for the six months ended June 30, 2015 are collectively referred to as the pro forma statements of income (loss).

The historical consolidated financial information of Ballard Power and Protonex has been adjusted in the pro forma financial statements to give effect to pro forma events that are (1) directly attributable to the combination, (2) factually supportable, and (3) with respect to the pro forma statements of income (loss), expected to have a continuing impact on the combined results. The pro forma financial statements should be read in conjunction with the

71

Table of Contents

accompanying notes to the pro forma financial statements. In addition, the pro forma financial statements were based on and should be read in conjunction with the following historical consolidated financial statements and accompanying notes of Ballard Power and Protonex for the applicable periods:

· Separate historical audited financial statements of Ballard Power as of and for the year ended December 31, 2014 and the related notes included in Ballard Power’s Annual Report on Form 40-F for the year ended December 31, 2014;

· Separate historical audited financial statements of Protonex as of and for the year ended September 30, 2014 and the related notes included in Protonex’s consolidated financial statements for the year ended September 30, 2014;

· Separate historical unaudited financial statements of Ballard Power as of and for the three and six months ended June 30, 2015 and the related notes included in Ballard Power’s Current Report on Form 6-K for the period ended June 30, 2015; and

· Separate historical unaudited financial statements of Protonex as of and for the three and six months ended March 31, 2015 and the related notes included in Protonex’s consolidated financial statements for the period ended March 31, 2015.

The pro forma financial statements have been presented for informational purposes only and are not necessarily indicative of what the combined company’s financial position or results of operations actually would have been had the combination been completed as of the dates indicated. In addition, the unaudited pro forma condensed combined financial information does not purport to project the future financial position or operating results of the combined company.

The pro forma financial statements have been prepared using the acquisition method of accounting in accordance with IFRS 3 Business Combinations, with Ballard Power considered as the accounting acquirer and Protonex as the accounting acquiree. Accordingly, consideration to be given by Ballard Power to complete the merger with Protonex will be allocated to assets and liabilities of Protonex based on their estimated fair values as of the completion date of the merger. As of the date of this report, Ballard Power has not completed the detailed valuation studies necessary to arrive at the required estimates of the fair value of the Protonex assets to be acquired and the liabilities to be assumed and the related allocations of purchase price, nor has it identified all of the adjustments necessary to conform Protonex’s accounting policies to Ballard Power’s accounting policies.

A final determination of the fair value of the Protonex assets and liabilities will be based on the actual net tangible and intangible assets and liabilities of Protonex that exist as of the date of completion of the merger and, therefore, cannot be made prior to the completion of the transaction. Additionally, the value of the share consideration to be given by Ballard Power to complete the merger will be determined based on the trading price of Ballard Power’s common shares at the time of the completion of the merger. Accordingly, the pro forma purchase price adjustments are preliminary and are subject to material adjustments as additional information becomes available and as additional analyses are performed. The preliminary pro forma purchase price adjustments have been made solely for the purpose of providing the pro forma financial statements presented below. Ballard Power estimated the fair value of Protonex’s assets and liabilities based on discussions with Protonex management and preliminary due diligence. Upon completion of the merger, final valuations will be

72

Table of Contents

performed. Increases or decreases in the fair value of relevant statement of financial position amounts will result in adjustments to the pro forma statement of financial position and the pro forma statements of income (loss) as presented. There can be no assurance that such finalization will not result in material changes. Ballard Power intends to complete the valuations and other studies upon completion of the merger and will finalize the purchase price allocation as soon as practicable within the measurement period in accordance with IFRS 3, but in no event later than one year following the closing date of the merger.

Upon completion of the merger, Ballard Power will perform a detailed review of Protonex’s accounting policies. As a result of that review, Ballard Power may identify differences between the accounting policies of the two companies that, when conformed, could have a material impact on the pro forma financial statements. At this time, Ballard Power is not aware of any material accounting policy differences.

The pro forma financial statements do not reflect any cost savings, operating synergies or revenue enhancements that the combined company may achieve as a result of the merger, or the costs to combine the operations of Ballard Power and Protonex, or the costs necessary to achieve these cost savings, operating synergies and revenue enhancements.

In addition, the pro forma financial statements (excluding the balance sheet) do not include an estimate of the one-time expenses directly attributable to the merger including brokerage, professional and other fees expected to be incurred by Ballard Power and Protonex pursuant to the closing of the merger agreement. Transaction-related expenses are not considered part of the purchase price allocation and are instead expensed as incurred.

Notes to the Unaudited Pro Forma Condensed Combined Financial Information

(Expressed in thousands of U.S. dollars, except share and per-share amounts)

1. Basis of presentation:

On June 29, 2015, Ballard Power and Protonex announced that they had entered into an Agreement and Plan of Merger pursuant to which Ballard Power will issue shares of its common stock in exchange for all of Protonex’s outstanding common stock. The number of shares to be ultimately issued by Ballard Power is subject to adjustment on closing based on Protonex’s actual bank indebtedness and Protonex’s actually incurred transaction and change of control costs as of the date of closing, as these items are to be repaid by Ballard Power on the closing date. Based on Protonex’s estimated bank indebtedness on closing of $2,675, and Protonex’s estimated transaction and change of control costs on closing of $1,755, Ballard Power would issue approximately 11,214,912 common shares to complete the merger.

The accompanying unaudited pro forma financial statements present the pro forma consolidated financial position and results of operations of the combined company based upon the historical financial statements of Ballard Power and Protonex, after giving effect to the merger, the termination and repayment of certain of Protonex’s bank indebtedness on closing, payment of certain of Protonex’s transaction costs and change of control costs in connection with the merger on closing, and other adjustments described in these notes, and are intended to reflect the impact of the combination on Ballard Power’s consolidated financial statements. The unaudited pro forma financial statements have been prepared in accordance with IFRS.

· The pro forma statement of financial position combines the unaudited historical consolidated statement of financial position of Ballard Power as of June 30, 2015 and the unaudited historical consolidated balance sheet of Protonex as of March 31, 2015, giving effect to the combination as if it had been consummated on June 30, 2015.

· The pro forma statement of income (loss) and other comprehensive income (loss) for the year ended December 31, 2014 combines the audited historical consolidated statement of loss and other comprehensive loss of Ballard Power for the year ended December 31, 2014 and the audited historical consolidated statement of operations of Protonex for the year ended September 30, 2014, giving effect to the combination as if it had been consummated on January 1, 2014, the beginning of Ballard Power’s most recently completed fiscal year.

· The pro forma statement of income (loss) and other comprehensive income (loss) for the six months ended June 30, 2015 combines the unaudited historical consolidated statement of profit or loss and other comprehensive income (loss) of Ballard Power for the six months ended June 30, 2015 and the unaudited historical consolidated statements of operations of Protonex for the six months ended March 31, 2015, giving effect to the combination as if it had been consummated on January 1, 2014, the beginning of Ballard Power’s most recently completed fiscal year.

The combination will be accounted for using the acquisition method of accounting in accordance with IFRS 3, “Business Combinations”. As the accounting acquirer, Ballard Power will account for the transaction by using Ballard Power historical information and accounting policies and adding the assets and liabilities of Protonex as of the completion date of the combination at their respective fair values. The determination of the fair value of the net assets acquired is preliminary, pending finalization of various estimates and analyses. Since these pro forma financial statements have been prepared based on preliminary estimates of purchase consideration and fair values of assets and liabilities attributable to the combination,

77

Table of Contents

BALLARD POWER SYSTEMS INC.

Notes to the Unaudited Pro Forma Condensed Combined Financial Information

(Expressed in thousands of U.S. dollars, except share and per-share amounts)

the actual amounts eventually recorded for the combination may differ materially from the information presented. The pro forma financial statements do not reflect the impact of possible revenue or earnings enhancements or cost savings from operating efficiencies or synergies. Also, the pro forma financial statements do not reflect possible adjustments related to restructuring or integration activities that have yet to be determined or transaction or other costs following the combination that are not expected to have a continuing impact on the business of the combined company. Furthermore, the pro forma financial statements (excluding the balance sheet) do not include an estimate of the one-time transaction-related expenses anticipated to be incurred prior to, or concurrent with, the closing of the combination.

2. Preliminary Merger Consideration:

The preliminary purchase price in these pro forma financial statements is based on an agreed upon Protonex enterprise value of $30 million. Concurrent with closing, Ballard Power will repay certain of Protonex’s debt obligations and certain of Protonex’s transaction and change of control costs. The final amount of these debt obligations and transaction costs, which will not be known until closing, will be paid in cash by Ballard Power on closing and will be deducted from the $30 million enterprise value to arrive at the preliminary value of Ballard Power common shares to be issued to Protonex’s shareholders. The number of Ballard Power common shares to be issued to Protonex’s shareholders will then be calculated based upon a fixed price of $2.28 per Ballard Power common share being the weighted average closing price of Ballard Power common shares for the 10-days ending June 26, 2015.

The preliminary total purchase price of the proposed transaction of $30 million allocated between Ballard Power common share consideration and Ballard Power cash commitments to be paid on closing is estimated as follows (in thousands of U.S. dollars except for number of shares):

Agreed upon Enterprise value of Protonex |  | $ | 30,000 |
Less: estimated cash settlement by Ballard Power of Protonex bank indebtedness on closing |  | (2,675 | )
Less: estimated cash settlement by Ballard Power of Protonex transaction and change of control costs on closing |  | (1,755 | )
Total estimated Preliminary Merger Consideration (preliminary estimated fair value of Ballard Power common share consideration to Protonex stock holders) |  | $ | 25,570 |
Estimated number of Ballard Power common shares to be issued to Protonex stock holders (at a fixed price of $2.28 per share) |  | 11,214,912 |

The share price of Ballard Power’s common shares used to estimate the preliminary purchase price is fixed at $2.28 per share, the weighted average closing price of Ballard Power common shares for the 10-days ending June 26, 2015. The ultimate accounting value of the share consideration given by Ballard Power to complete the merger will instead be determined based on the

78

Table of Contents

BALLARD POWER SYSTEMS INC.

Notes to the Unaudited Pro Forma Condensed Combined Financial Information

(Expressed in thousands of U.S. dollars, except share and per-share amounts)

trading price of Ballard Power’s common shares at the time of the completion of the merger. Accordingly, the total amount of merger consideration and the preliminary purchase price are preliminary and are subject to material adjustment. An increase or decrease in the market price of Ballard Power’s common stock of 50% would increase or decrease the value of the Ballard Power common stock to be received by Protonex stockholders upon completion of the transactions as set forth below, with a corresponding increase or decrease in the fair value of goodwill or intangible assets that will be recorded in connection with the transaction (in thousands, except per-share amounts):

|  | Percentage change in stock price |
|  | -50% |  | 50% |
Market price of a Ballard Power common share |  | $ | 1.14 |  | $ | 3.42 |
Fair value of Ballard Power common shares to be issued |  | $ | 12,785 |  | $ | 38,355 |

Completion of the merger is subject to approval by a majority of the stockholders of Protonex. As of the date of this report, the combination is expected to be completed during the third calendar quarter of 2015.

The closing market price of Ballard Power’s common shares was $2.09 per share on June 30, 2015 and $1.35 on July 31, 2015.

3. Estimate of Assets to be Acquired and Liabilities to be Assumed:

The table below represents a preliminary estimate of Protonex’s tangible and intangible assets acquired and liabilities assumed based on Ballard Power’s preliminary estimate of their respective fair values as of March 31, 2015 (in thousands of U.S. dollars):

Cash and cash equivalents |  | $ | 746 |
Other current assets excluding cash and cash equivalents |  | 2,554 |
Property, plant and equipment and other long-term assets |  | 2,065 |
Goodwill |  | 21,035 |
Intangible assets |  | 5,000 |
Bank operating line (to be repaid on closing) |  | (2,675 | )
Other current liabilities excluding bank operating line (including $1,755 of Protonex transaction and change of control costs to be repaid on closing) |  | (3,132 | )
Non-current liabilities |  | (23 | )
Deferred tax liability |  | — |
Total Preliminary Merger Consideration |  | $ | 25,570 |

Upon completion of the fair value assessment after the merger, it is anticipated that the final determination of fair value of net assets acquired will differ from the preliminary assessment outlined above. Any changes to the initial estimates of the fair value of assets and liabilities will be recorded as adjustments to those assets and liabilities and residual amounts will be allocated to goodwill and / or intangible assets.

4. Pro Forma Adjustments to the Statement of Financial Position:

Certain reclassifications and financial statement account descriptions have been made to conform Protonex’s historical reported balances to Ballard Power’s financial statement basis of presentation.

The following represents an explanation of the various adjustments to the pro forma statement of financial position:

(a) Cash. Adjustment to cash of ($4,430) reflects the estimated repayment of certain of Protonex’s liabilities due upon closing consisting of estimated repayment of the bank indebtedness of ($2,675) and certain of Protonex’s transaction and estimated change of control costs related to the merger of ($1,755).

(b) Property, plant and equipment. Adjustment to property, plant and equipment of $1,680 reflects the preliminary estimated excess of the fair value of certain property, plant and equipment over its historic cost net of amortization, and

80

Table of Contents

BALLARD POWER SYSTEMS INC.

Notes to the Unaudited Pro Forma Condensed Combined Financial Information

(Expressed in thousands of U.S. dollars, except share and per-share amounts)

consists primarily of certain manufacturing equipment. The property, plant and equipment assets are expected to be amortized on a straight-line basis over their estimated useful life of 5-years. The property, plant and equipment asset fair values and estimated useful lives are subject to material revision as the purchase price allocation is completed.

(c) Intangible assets. Adjustment to intangible assets of $5,000 reflects the preliminary estimated excess of the fair value of identified intangible assets over its historic cost net of amortization, and consists primarily of patents and patent applications, in process research and development costs, customer contracts and related customer relationships and order backlog. Protonex has historically expensed as incurred all costs related to research and development activities. The intangible assets are expected to be amortized on a straight-line basis over their estimated useful life of 5-years. The intangible asset fair values and estimated useful lives are subject to material revision as the purchase price allocation is completed.

(d) Goodwill. Adjustment to goodwill of $13,218 reflects the excess of the estimated purchase price over the estimated underlying fair value of net tangible and identifiable intangible assets identified in the preliminary purchase price allocation. The goodwill fair value is subject to material revision as the purchase price allocation is completed.

(e) Bank operating line. Adjustment to bank indebtedness of ($2,216) reflects the estimated net repayment of Protonex’s bank obligations at the time of closing of ($2,675) including an estimate of accrued interest and net additional draws of ($459) to be incurred by Protonex from March 31, 2015 to the estimated date of closing (pro forma adjustment 4(a)).

(f) Accounts payable and accrued liabilities. Adjustment to accounts payable and accrued liabilities of $1,300 reflects the estimated brokerage, professional and other direct expenses to be incurred by Ballard Power related to the merger. Additional estimated expenses of $1,755 related to brokerage, professional and other change of control expenses to be incurred by Protonex related to the merger are to be repaid on closing (pro forma adjustment (4a)).

(g) Deferred tax liability. Adjustment to deferred tax liability of ($1,630) reflects the estimated elimination of a historic Protonex deferred tax liability that arose as a result of a historic Protonex acquisition. On the completion of the merger, the estimated combined Ballard Power and Protonex U.S. deferred tax assets are expected to exceed the historic Protonex deferred tax liability. The deferred tax liability fair value is subject to material revision as the purchase price allocation is completed and the availability of historic tax losses on a combined basis is assessed.

(h) Share capital. Adjustment to share capital of $25,249 reflects the preliminary estimated fair value of Ballard Power common shares to be issued of $25,570 (11,214,912 shares at a deemed price of $2.28 per share) to acquire 100% of Protonex’s common and preferred stock including the conversion or elimination of all of Protonex’s outstanding option and warrant awards prior to closing, less the elimination of Protonex’s historical preferred and common stock balances of ($321) on acquisition. The final fair value of the Ballard Power common share

81

Table of Contents

BALLARD POWER SYSTEMS INC.

Notes to the Unaudited Pro Forma Condensed Combined Financial Information

(Expressed in thousands of U.S. dollars, except share and per-share amounts)

consideration to be exchanged in the merger agreement is subject to material revision as the final fair value of the Ballard Power share consideration to complete the merger will be determined primarily based on the trading price of Ballard Power’s common shares at the time of the completion of the merger, as compared to the trading price as of June 26, 2015. Any change to the initial estimate of the fair value of Ballard Power common share consideration will be recorded as a purchase price adjustment primarily impacting goodwill and / or intangible assets.

(i) Contributed surplus. Adjustment to contributed surplus of ($69,089) reflects the elimination of Protonex’s historical contributed surplus balance on acquisition.

(j) Accumulated deficit. Adjustment to accumulated deficit of ($61,854) reflects the elimination of Protonex’s historical accumulated deficit balance of ($63,154) on acquisition, less Ballard Power’s estimated transactional costs to complete the merger of $1,300 (pro forma adjustment 4(f)).

5. Pro Forma Adjustments to the Statement of Income (Loss) and Other Comprehensive Income (Loss):

Certain reclassifications have been made to conform Protonex’s historical reported balances and financial statement account descriptions to Ballard Power’s financial statement basis of presentation.

The following represents an explanation of the various adjustments to the pro forma statement of income (loss) and other comprehensive income (loss):

(a) Cost of product and service revenues (“COGS”). Adjustment to COGS of $336 for the year ended December 31, 2014 and $168 for the six months ended June 30, 2015 reflects the estimated increase in amortization expense to amortize the excess of the fair value of property, plant and equipment over the historical balance of capitalized manufacturing equipment, based on an estimated useful life of 5 years (pro forma adjustment 4(b)).

(b) Research and product development expenses (“R&PD”). Adjustment to R&PD of $1,000 for the year ended December 31, 2014 and $500 for the six months ended June 30, 2015 reflects the estimated increase in amortization expense to amortize the excess of the fair value of identifiable intangible assets over the historical balance of capitalized intangible assets, based on an estimated useful life of 5 years (pro forma adjustment 4(c)).

(c) Finance expense. Adjustment to finance expense of $330 for the year ended December 31, 2014 and $235 for the six months ended June 30, 2015 reflects the elimination of historical interest expense incurred on Protonex’s bank indebtedness which is expected to be repaid by Ballard Power as a condition of closing (pro forma adjustments 4(a), 4(e)).

(d) Income tax expense. Adjustment to income tax expense of $203 for the year ended December 31, 2014 and $102 for the six months ended June 30, 2015 represents the elimination of historical income tax expense incurred by Protonex as

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS OF THE BUSINESS OF PROTONEX

You should read the following Management Discussion & Analysis (“MD&A”) in conjunction with Protonex’s unaudited interim condensed consolidated financial statements and accompanying notes for the three and six months ended March 31, 2015 and 2014, as well as Protonex’s latest audited financial statements as of September 30, 2014 and 2013 and for each of the three years in the period ended September 30, 2014 all appearing in this Form F-4. The financial statements have been recorded in accordance with US GAAP.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires Protonex to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Protonex bases its estimates and judgments on historical experience and on various other factors that are considered reasonable under the circumstances. Actual results could differ materially from these estimates. The carrying amounts of Protonex’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, capital leases, accrued liabilities and long-term debt approximate their fair values due to the short-term nature of these instruments or their market rates of interest.

Business Overview

Protonex is a leading designer and manufacturer of compact, high performance power management and portable fuel cell power generation solutions, with $13.8 million in total revenues for fiscal year 2014. With products including fuel cells, portable battery chargers and power managers, the Protonex sells its products primarily to military and government sectors, but also to the commercial sector. Customers include the US Army, United States Special Operations Command (SOCOM) and other notable military/government entities, in addition to commercial customers including Lockheed Martin and Raytheon. In the fuel cell category, it offers products in both Proton Exchange Membrane (PEM) and Solid Oxide (SO) technologies, which can power off-grid applications longer than conventional energy solutions. Holding a suite of 55 granted and 41 pending patents, Protonex’s products offer a significant improvement over legacy battery technologies, providing a substantial reduction in weight while improving performance, efficiency and functionality.

Factors Influencing Results of Operations

Revenue: Protonex derives revenues from cost sharing, cost-reimbursement (cost-type), fixed price and cost-plus contracts with various government groups and agencies, with revenues recognized when the related costs are incurred and related services are performed. Contract costs primarily include direct labor, consultants, sub-contractors, materials, and other specific administrative costs related to the project. Deferred revenue represents amounts received in advance of services being performed and/or delivery of products. Unbilled accounts receivable represents revenue recognized under the contracts in advance of billings.

Revenues from research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract, whether billed or unbilled. In many cases, Protonex is reimbursed only a portion of the costs incurred or to be incurred on the contract. Revenues from government funded research, development and demonstration programs are generally multi-year, cost reimbursement and/or cost-shared type contracts or cooperative agreements. Protonex is reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract agreements.

Revenues from product sales are recognized upon the delivery of units to customers, provided that there is evidence that an arrangement exists, the fee is fixed or determinable, and collectability of the related receivable is probable. If there are acceptance provisions, revenue is recognized upon acceptance. Deferred revenue represents amounts received from customers in advance of shipments.

Operating expenses: The largest portion of operating expenses consists of research and development costs, materials, cash and non-cash compensation and benefits associated with engineering personnel and related expenses. Other related expenses include travel, subcontracting costs, third-party vendor payments and non-billable expenses

85

Table of Contents

associated with the delivery of services to customers. Protonex considers the relationship between project personnel expenses and service revenue to be an important measure of operating performance. The relationship between research and development expenses and contract revenue is driven largely by the chargeability of engineering personnel to current research and development contracts, versus the non-billable costs associated with securing new customer engagements and developing new service offerings. The remainder of recurring operating expense consists of sales and marketing expenses associated with expanding the customer base for Protonex’ power manager and fuel cell products. These expenses include salaries for sales personnel and outside sales consultants. Management and administrative support expenses consist primarily of the costs associated with operations, including finance, information systems, human resources, purchasing, facilities (including the rent of office space) and other administrative support for engineering personnel.

Results for the three and six month periods ended March 31, 2015 compared to results for the three and six month periods ended March 31, 2014:

Total revenues:

Total revenues decreased by $0.2 million, or (8.1)%, to $2.7 million during the three-month period ended March 31, 2015, compared to total revenue of $3.0 million in the three-month period ended March 31, 2014. The primary driver of this decrease during the second quarter of fiscal 2015 is attributable to both the completion of a large government development contract and the completion of a large U.S. Army product order.

Total revenues decreased by $0.6 million, or (10.1)%, to $5.7 million during the six-month period ended March 31, 2015, compared to total revenue of $6.4 million in the six-month period ended March 31, 2014. The primary driver of this decrease during the first half of fiscal 2015 is attributable to the completion of large government development contracts, in addition to delayed product orders and new contract starts relative to the prior fiscal year.

Total cost of revenues:

Total cost of revenue decreased by $0.3 million, or (20.3)%, to $1.5 million during the three-month period ended March 31, 2015, compared to total cost of revenue of $1.8 million in the three-month period ended March 31, 2014. The primary driver of this decrease is attributable to the completion of a substantial subcontractor effort on a government development contract in early fiscal 2015.

Total costs of revenue decreased by $0.5 million, or (14.9)%, to $3.2 million during the six-month period ended March 31, 2015, compared to total costs of revenue of $3.7 million in the six-month period ended March 31, 2014. The primary driver of this decrease is attributable to the completion of large government development power manager contracts that included substantial subcontractor efforts with low margins.

Research and development:

Research and development expenses increased by $0.1 million, or (12.1)%, to $1.1 million during the three-month period ended March 31, 2015, compared to research and development expenses of $1.0 million in the three-month period ended March 31, 2014. The primary driver of this increase during the second quarter of fiscal 2015 is attributable to more internal development efforts on advancing both the power manager and Solid Oxide Fuel Cell (SOFC) platforms.

Research and development increased by $0.2 million, or (11.0)%, to $2.0 million during the six-month period ended March 31, 2015, compared to research and development expenses of $1.8 million in the six-month period ended March 31, 2014. Again, the primary driver of this increase during the first half of fiscal 2015 is attributable to more internal development efforts on advancing both the power manager and SOFC platforms.

Sales and marketing:

Sales and marketing expenses decreased by $33.0 thousand, or (11.4)%, to $0.3 million during the three-month period ended March 31, 2015, compared to Sales and marketing expenses of $0.3 million in the three-month period ended March 31, 2014. The primary driver of this decrease during the second quarter of fiscal 2015 is attributable to timing of tradeshow events and related travel.

Sales and marketing expenses increased by $40.0 thousand, or (7.3)%, to $0.6 million during the six-month period ended March 31, 2015, compared to sales and marketing expenses of $0.5 million in the six-month period ended March 31, 2014. Again, the primary driver of this increase during the first half of fiscal 2015 is attributable to timing of tradeshow events and related travel.

General and administrative:

General and administrative expenses decreased by $40.6 thousand, or (10.7)%, to $0.3 million during the three-month period ended March 31, 2015, compared to general and administrative expenses of $0.4 million in the three-

Table of Contents

month period ended March 31, 2014. The primary driver of this decrease during the second quarter of fiscal 2015 is attributable to reduction in discretionary travel, legal and consulting expenses.

General and administrative expenses decreased by $0.1 million, or (9.4)%, to $0.6 million during the six-month period ended March 31, 2015, compared to general and administrative expenses of $0.7 million in the six-month period ended March 31, 2014. Again, the primary driver of this decrease during the first half of fiscal 2015 is attributable to reduction in discretionary travel, legal and consulting expenses.

Total other expenses, net:

Total other expenses, net increased by $77.6 thousand, or (152.0)%, to $0.1 million during the three-month period ended March 31, 2015, compared to total other expenses, net of $51.0 thousand in the three-month period ended March 31, 2014. The primary driver of this increase during the second quarter of fiscal 2015 is attributable to the increased interest expense related to the WindSail growth loan as compared to the same period during 2014.

Total other expenses, net increased by $0.1 million, or (84.8)%, to $0.2 million during the six-month period ended March 31, 2015, compared to total other expenses, net of $0.1 million in the six-month period ended March 31, 2014. Again, the primary driver of this increase during the first half of fiscal 2015 is attributable to the increased interest expense related to the WindSail growth loan as compared to the same period during 2014.

Provision for income taxes:

Provision for income taxes decreased by $4.0 thousand, or (7.3)%, to $51.0 thousand during the three-month period ended March 31, 2015, compared to the provision for income taxes of $55.0 thousand in the three-month period ended March 31, 2014. The primary driver of this decrease during the second quarter of fiscal 2015 is attributable to reduced estimated income tax provision during fiscal 2015 as compared to fiscal 2014.

Provision for income taxes decreased by $8.0 thousand, or (7.3)%, to $102.0 thousand during the six-month period ended March 31, 2015, compared to the provision for income taxes of $110.0 thousand in the six-month period ended March 31, 2014. The primary driver of this decrease during the first half of fiscal 2015 is attributable to reduced estimated income tax provision during fiscal 2015 as compared to fiscal 2014.

Net Loss:

Net loss decreased by $14.4 thousand, or (2.4)%, to $(581.3) thousand during the three-month period ended March 31, 2015, compared to net loss of $(595.7) thousand in the three-month period ended March 31, 2014. The primary driver of this improved loss during this comparable period was attributable to improved gross margins that were slightly offset by higher research and development expenses.

Net loss increased by $0.4 million, or (51.0)%, to $(1.1) million during the six-month period ended March 31, 2015, compared to net loss of $(0.7) million in the six-month period ended March 31, 2014. The primary driver of this increased loss during this comparable period was attributable to higher sales and marketing and research and development expenses in support of advancing both the power manager and SOFC platforms.

The primary driver of this increase during fiscal 2014 as compared to fiscal 2013 is attributable to increased interest expense related to the WindSail growth loan.

Provision for income taxes:

Provision for income taxes decreased by $17.3 thousand, or (7.8)%, to $0.20 million during the year ended September 30, 2014, compared to provision for income taxes of $0.22 million in the year ended September 30, 2013. The primary driver of this decrease during fiscal 2014 as compared to fiscal 2013 is attributable to a reduced estimated income tax provision.

Net Loss:

Net loss decreased by $0.6 million, or (35.9)%, to $(1.1) million during the year ended September 30, 2014, compared to the net loss of $(1.7) million in the year ended September 30, 2013. The primary driver of this decrease during fiscal 2014 as compared to fiscal 2013 is attributable to the addition of new development contracts associated with the SOFC and power manager platforms, large scale product orders, and increased utilization of engineering labor on billable programs.

Results for the Fiscal Year ended September 30, 2013 Compared to Results for the Fiscal Year Ended September 30, 2012:

Total revenues:

Total revenue increased by $2.9 million, or (28.2)%, to $13.0 million during the year ended September 30, 2013, compared to total revenue of $10.1 million in the year ended September 30, 2012.

The primary driver of this decrease in losses during fiscal 2013 as compared to fiscal 2012 is attributable to the substantial increase in power manager product orders.

Liquidity and Capital Resources

The following table summarizes Protonex cash flow activities for the periods indicated:

|  | For the six months ended March 31, |
|  | 2015 |  | 2014 |
Cash flows (used in) provided by: |  |  |  |  |
Cash flow from operations |  | $ | (806,801 | ) | $ | 580 |
Cash flow from investment activities |  | (28,391 | ) | (34,051 | )
Cash flow from financing activities |  | (12,203 | ) | (20,571 | )
Cash used during the period |  | $ | (847,395 | ) | $ | (54,042 | )

As of March 31, 2015, cash and cash equivalents totaled $0.7 million, a $(0.2) million decrease compared to the March 31, 2014 balance of $0.9 million. The primary driver of the decrease in cash during the first half of fiscal 2015 was higher net operating losses and higher working capital requirements.

|  | For the fiscal years ended September 30, |
|  | 2014 |  | 2013 |  | 2012 |
Cash flows (used in) provided by: |  |  |  |  |  |  |
Cash flow from operations |  | $ | 222,833 |  | $ | (1,415,119 | ) | $ | (45,110 | )

Cash used during the period |  | $ | 634,143 |  | $ | (179,617 | ) | $ | (350,331 | )

As of September 30, 2014, cash and cash equivalents totaled $1.6 million, a $0.6 million increase from the September 30, 2013 balance of $1.0 million. This cash increase was partially attributable to the last $0.5 million draw on the WindSail Capital growth loan, in addition to decreased working capital requirements.

As of September 30, 2013, Protonex had cash and cash equivalents of approximately $1.0 million, a $(0.1) million decrease from the September 30, 2012 balance of $1.1 million. The primary driver for this cash decrease was net operating losses as Protonex expanded production capacity, which was largely offset by the initial $1.5 million draw on the WindSail Capital growth loan.

Protonex periodically reassesses the adequacy of their liquidity position, taking into consideration current and anticipated operating cash flow and anticipated capital expenditures. The pace at which Protonex will either generate or consume cash will be dependent upon future operations and the level of demand for Protonex’ services and products on an ongoing basis.

Cash flow from operating activities is driven by collections of development contract billings and product sales. Cash used in operations predominantly relates to employee compensation, purchase of raw materials, rent expense and professional fees. Accrued payroll and related liabilities fluctuate from period to period based on the timing of the normal payroll cycle and the timing of variable compensation payments. Annual components of variable compensation plans are paid in the first quarter of the following year, causing fluctuations in cash flow from quarter to quarter. Accounts payable and accrued expenses are most significantly impacted by the timing of product orders and materials related to development contract efforts.

All capital expenditures are discretionary as Protonex currently has no long-term commitments for capital expenditures.

Net cash provided by financing activities was $0.5 million during the year ended September 30, 2014, compared to net cash provided by financing activities of $1.3 million during the year ended September 30, 2013. This cash was associated with the initial $1.5 million, and subsequent $0.5 million funding, on the WindSail Capital growth loan.

The WindSail growth loan was secured in March 2013, and provided for an initial term loan of $1.5 million, with an additional $0.5 million available for subsequent use, which was received in September 2014. The outstanding borrowings of $2.0 million at March 31, 2015 are secured by Protonex’ accounts receivable, inventory and intellectual property. The agreement provided for an adjustable interest rate of prime plus 3.25% payable in cash, plus 3.25% interest that is capitalized, compounded and added to the unpaid principal of the term loan. Total capitalized interest of $261,646 was added to the unpaid principal balance as of March 31, 2015. The outstanding principal and capitalized interest is due and payable in March 2016. Protonex is required to maintain certain financial covenants under the growth loan. On March 30, 2015, Protonex signed an amendment to the loan that adjusted loan covenants. As of March 31, 2015, Protonex was in compliance with such covenants.

In May 2015, Protonex secured a $2.0 million working capital line of credit with Silicon Valley Bank. Outstanding borrowings were secured by Protonex’s accounts receivable and inventory. The bank has a senior blanket lien on all Protonex assets, including IP. The agreement provides for an adjustable interest rate of prime plus 2.5% or 1.5%, depending on balance sheet liquidity ratios.

Note 1: Includes facility lease amendment which extends for another five years.

There were no material changes to Protonex’s commitments and contingencies from the September 30, 2014 annual report, except for an amendment to the current facility lease, which extends the lease period for another five years and has payments of $0.3 million for 2018 through 2020. Lease payments were approximately $0.3 million for each of the fiscal years ended September 30, 2014, 2013 and 2012, respectively. For the six months ended March 31, 2015 and 2014 respectively, total rent and related expenses under the agreements was approximately $0.2 million for each period.

Critical Accounting Policies and Estimates

Critical Accounting Policies

Protonex’ consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These accounting principles require Protonex to make certain estimates, judgments and assumptions. Management believes that the estimates, judgments and assumptions which are relied upon are reasonable based upon information available to at the time that they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the periods presented. To the extent there are differences between these estimates, judgments or assumptions and actual results, Protonex’ financial statements may be affected. The accounting policies that management believes are the most critical to aid in fully understanding and evaluating the reported financial results include the following:

· | Revenue recognition;
· | Goodwill, other intangible assets and impairment of long-lived assets.

Revenue recognition and deferred revenues:

Revenues from cost sharing, cost-reimbursement (cost-type), fixed price and cost plus contracts with various government groups and agencies are recognized when the related costs are incurred and related services are performed. Contract costs primarily include direct labor, consultants, sub-contractors, materials, and other specific administrative costs related to the project. Deferred revenue represents amounts received in advance of services being performed and or delivery of products. Unbilled accounts receivable represents revenue recognized under the contracts in advance of billings.

Revenues from research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract, whether billed or unbilled. In many cases, Protonex is reimbursed only a portion of the costs incurred or to be incurred on the contract. Revenues from government funded research, development and demonstration programs are generally multi-year, cost

Table of Contents

reimbursement and/or cost-shared type contracts or cooperative agreements. Protonex is reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract agreements.

Revenues from product sales are recognized upon the delivery of units to customers, provided that there is evidence that an arrangement exists, the fee is fixed or determinable, and collectability of the related receivable is probable. If there are acceptance provisions, revenue is recognized upon acceptance. Deferred revenue represents amounts received from customers in advance of shipments.

Valuation of goodwill and other intangible assets:

Protonex evaluates the recoverability of goodwill and intangible assets with indefinite useful lives as of the end of each fiscal year, or more frequently if events or changes in circumstances (such as a decline in sales, operations, or cash flows, or material adverse changes in the business climate) indicate that the carrying value of an asset might be impaired. Protonex operates as a single reporting unit. In 2012, Protonex adopted Accounting Standards Update (ASU) No. 2011-08, Intangibles - Goodwill and Other (Topic 350), Testing Goodwill for Impairment, which includes the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount before performing the two-step impairment test as required in Accounting Standards Codification (ASC) 350, Intangibles - Goodwill and Other. At September 30, 2014, Protonex performed a qualitative goodwill impairment analysis. The September 30, 2014 impairment analysis included an assessment of certain qualitative factors including, but not limited to, overall financial performance, and macroeconomic and industry conditions. Protonex considered the qualitative factors and weighed the evidence obtained, and determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. Although Protonex believes the factors considered in the impairment analysis are reasonable, significant changes in any one of the assumptions used could produce a different result.

Protonex examines on a periodic basis the carrying value of its long-lived tangible and intangible assets to determine whether there are any impairment losses. If indicators of impairment were present with respect to long-lived tangible and intangible assets used in operations and undiscounted future cash flows were not expected to be sufficient to recover the assets’ carrying amount, an impairment loss would be charged to expense in the period the impairment is identified based on the fair value of the asset less any costs of disposal. Protonex believes no impairment exists as of September 30, 2014.

In addition, directors have a duty of loyalty, which may be summarized as the duty to act in good faith, not out of self-interest and in a manner which the directors reasonably believe to be in the best interests of the stockholders pursuant to the “business judgment rule.” |  | The CBCA requires directors of a Canadian corporation to act honestly and in good faith with a view to the best interests of the Canadian corporation. The duty of care requires that the directors exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances.
LIMITATION ON LIABILITY OF DIRECTORS
PROTONEX |  | BALLARD
Under the DGCL, directors shall not be personally liable to the corporation or any stockholder for monetary damages for breach of fiduciary duty as a director, except (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) for intentional or negligent payment of unlawful dividends or stock purchases or redemptions; or (iv) for any transaction from which the director derived an improper personal benefit. Under the DGCL, Protonex shall have the power, and under Protonex’s certificate of incorporation, it is required, to indemnify any person made a party or threatened to be made a party to any type of proceeding (other than an action by or in the right of the corporation) because he or she is or was an officer, director, trustee, or employee of Protonex, or was serving at the request of Protonex as a director, officer, employee or agent of another corporation or entity, against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such proceeding.

A Canadian corporation may, if the person meets the conditions above and it is approved by a court, also indemnify an eligible director or officer in an action by or on behalf of the Canadian corporation. If a person meets the conditions above and was not judged by the court or other competent authority to have committed any fault or omitted to do anything that individual ought to have done, that person is entitled to be indemnified by the Canadian corporation in respect of all costs, charges and expenses reasonably incurred by the individual in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which the individual is subject because of the individual’s association with the Canadian corporation.

Under the DGCL, amendments to a Delaware corporation’s certificate of incorporation must be approved by a resolution of the board of directors declaring the advisability of the amendment, and by the affirmative vote of a majority of the outstanding shares entitled to vote. If an amendment would increase or decrease the number of authorized shares of such class, increase or decrease the par value of the shares of such class or alter or change the powers, preferences or other special rights of a class of outstanding shares so as to affect the class adversely, then a majority of shares of that class also must approve the amendment. The DGCL also permits a Delaware corporation to include a provision in its certificate of incorporation requiring a greater proportion of voting power to approve a specified amendment. Protonex’s certificate of incorporation provides that the |  | Under the CBCA, an amendment of the articles generally requires the approval of not less than two-thirds of the votes cast by stockholders entitled to vote on the resolution.

ANTI-TAKEOVER PROVISIONS
PROTONEX |  | BALLARD
Under Section 203 of the DGCL, unless a corporation in its certificate of incorporation or bylaws expressly elects otherwise (which Protonex has not done), a corporation is prohibited from engaging in a business combination with an interested stockholder (a person or group of affiliates owning at least 15% of the voting power of the corporation) for a period of three years after such interested stockholder became an interested stockholder unless (a) before the stockholder became an interested stockholder, the corporation’s board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder, (b) upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer, or (c) at or subsequent to the time the stockholder became an interested stockholder the business combination is approved by the board of directors and authorized by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder at an annual or special meeting of the stockholders of the corporation. Protonex does not have a stockholders’ rights plan. |  | The CBCA does not contain a comparable provision to that found in Section 203 the DGCL. However, certain Canadian securities regulatory authorities and the TSX have adopted Multilateral Instrument 61-101- Protection of Minority Security Holders in Special Transactions (“MI 61-101”) which address related party transactions. In a related party transaction, an issuer, among other things, acquires or transfers an asset or treasury securities, or assumes or transfers a liability, from or to a related party in one or any combination of transactions. A related party is defined in MI 61-101 to include directors, senior officers and holders of at least 10% of the issuer’s voting securities. MI 61-101 requires detailed disclosure in the proxy material sent to security holders in connection with a related party transaction. In addition, subject to certain exemptions, MI 61-101 requires the issuer to obtain a formal valuation of the subject matter of the related party transaction and any non-cash consideration and to include a summary of the valuation in the proxy material sent to security holders. MI 61-101 also requires that the stockholders of the issuer, other than the related party and its affiliates, separately approve the transaction by at least a simple majority. Ballard does not have a stockholders’ rights plan.
MERGER VOTE
PROTONEX |  | BALLARD
The DGCL provides that, unless otherwise provided in the certificate of incorporation or by-laws, the adoption of the Merger Agreement requires the approval of a majority of the outstanding stock of the corporation entitled to vote thereon. |  | The CBCA generally provides that the directors of an amalgamating corporation must submit the amalgamation agreement for approval at a meeting of the stockholders of the corporation. An amalgamation agreement is adopted when stockholders of each amalgamating corporation approve the amalgamation by not less than two-thirds of the votes cast by stockholders entitled to vote on the resolution.

APPRAISAL RIGHTS
PROTONEX |  | BALLARD
Under the DGCL, a stockholder of a constituent corporation in a merger may, under certain circumstances and upon meeting certain requirements, dissent from the merger by demanding payment in cash for his or her share equal to the “fair value” (excluding any appreciation or depreciation as a consequence or in expectation of the transaction) of such shares, as determined by agreement with the corporation or by an independent appraiser appointed by a court in action timely brought by the corporation or the dissenters. Delaware law grants appraisal rights only in the case of certain mergers and not in the case of a sale or transfer of assets or a purchase of assets for stock regardless of the number of shares being issued. Delaware law does not grant appraisal rights in a merger to holders of shares listed on a national securities exchange or held of record by more than 2,000 stockholders unless the plan of merger converts such shares into anything other than stock of the surviving corporation or stock of another corporation which is listed on a national securities exchange or held of record by more than 2,000 stockholders (or cash in lieu of fractional shares or some combination of the above). For a more detailed discussion regarding appraisal rights, see “The Merger —Appraisal Rights of Holders of Protonex Common Stock.” See also Appendix C hereto. |  | The CBCA provides that stockholders of a Canadian corporation are entitled to exercise dissent rights and demand payment for the fair value of the shares in respect of which the stockholder dissents. For this purpose, there is no distinction made between listed and unlisted shares. Dissent rights exist when there is a vote upon matters such as: · any amalgamation with another corporation (other than with certain affiliated corporations); · an amendment to the Canadian corporation’s articles of incorporation to add, change or remove any provisions restricting the issue, transfer or ownership of shares; · an amendment to the Canadian corporation’s articles of incorporation to add, change or remove any restriction upon the business or businesses that the corporation may carry on; · a continuance under the laws of another jurisdiction; · a sale, lease or exchange of all or substantially all the property of the Canadian corporation other than in the ordinary course of business; · a court order permitting a stockholder to dissent in connection with an application to the court for an order approving an arrangement proposed by the corporation; and · a “going private” transaction or a “squeeze-out” transaction. A stockholder is not entitled to dissent if an amendment to the articles is effected by a court order approving a reorganization or if an amendment to the articles is effected by a court order made in connection with an oppression remedy. Under the CBCA, a stockholder may, in addition to exercising dissent rights, seek an oppression remedy for any act or omission of a Canadian corporation which is oppressive or unfairly prejudicial to or that unfairly disregards a stockholder’s interest.

Independent Auditor’s Report

Board of Directors

Protonex Technology Corporation

Boston, Massachusetts

We have audited the accompanying consolidated financial statements of Protonex Technology Corporation and its subsidiary, which comprise the consolidated balance sheets as of September 30, 2014 and 2013, and the related consolidated statements of operations, changes in stockholders’ equity, and cash flows for each of the three years in the period ended September 30, 2014, and the related notes to the consolidated financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Notes to Consolidated Financial Statements

1. Organization and Basis of Presentation

Organization

Protonex Technology Corporation (the “Company”) was incorporated in October 2000, and performs engineering and development on fuel cell technology under cost sharing, cost-reimbursement (cost-type), fixed price and cost plus contracts. In addition, the Company assembles and sells related products. The Company is headquartered in Southborough, Massachusetts, and its primary market has been government agencies of the United States of America.

These consolidated financial statements have been prepared on a going concern basis. As such, they anticipate the realization of assets and the liquidation of liabilities in the normal course of business. The Company incurred net losses of $1,121,320, $1,748,196 and $2,013,195 for the years ended September 30, 2014, 2013 and 2012, respectively, and has an accumulated deficit of $62,094,552 as of September 30, 2014. The Company has funded these losses principally through equity financings, government contracts and a growth line of credit. Management believes that its government contract business, product sales growth, partnering with others and cash on hand, will be adequate to fund operations for at least twelve months from the date these financial statements were issued.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates and judgments on historical experience and on various other factors that are considered reasonable under the circumstances. Actual results could differ materially from these estimates.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Protonex Technology, LLC. All material intercompany transactions and balances have been eliminated in consolidation.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, capital leases, accrued liabilities and long-term debt approximate their fair values due to the short-term nature of these instruments or their market rates of interest.

F-11

Table of Contents

Protonex Technology Corporation

Notes to Consolidated Financial Statements

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Similarly, all money market accounts are considered cash equivalents.

The Company maintains its cash in bank deposit accounts, which, at times, may exceed federally insured limits, and in high quality, short-term, highly liquid investment securities. At September 30, 2014, $1,283,990 of cash equivalents exceed federally insured limits. Of the cash equivalents, $95,195 is maintained in a money-market fund that invests primarily in US Treasury Bills and the remaining balance is in a savings account. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from outstanding balances. The Company reviews accounts receivable on a monthly basis to determine if any receivables will potentially be uncollectible. Management provides for probable uncollectible amounts through a charge to operations and a credit to a valuation allowance based on its assessment. Based on experience, the Company does not record a reserve against the receivables from the agencies/groups of the United States Government. As of September 30, 2014 and 2013, 10% and 54%, respectively, of accounts receivable were from various government agencies. Government agencies and customers with government agencies as end user customers account for 93% of total accounts receivable at September 30, 2014.

Inventories and Related Allowance for Obsolete and Excess Inventory

Inventories consist primarily of raw materials and are recorded at the lower of cost or market. Cost is determined on a first-in, first-out basis. Reserves are recorded for slow moving, obsolete, non-sellable or unusable items and were approximately $164,000 and $145,000 at September 30, 2014 and 2013, respectively.

Property and Equipment

Property and equipment are recorded at cost and are depreciated using the straight-line method over their expected useful lives. Construction in progress represents fixed assets not yet placed in service, that at completion are transferred to the appropriate fixed asset category and depreciated on a straight-line basis over estimated useful lives of three - five years or remaining lease terms.

The current useful lives are:

Assets |  | Estimated Useful Lives
Furniture, fixtures and equipment |  | 5 years
Computer hardware and software |  | 3 - 5 years
Equipment under capital leases |  | 5 years
Leasehold improvements |  | Lesser of useful life or remaining lease term

Notes to Consolidated Financial Statements

Goodwill

The Company evaluates the recoverability of goodwill and intangible assets with indefinite useful lives as of the end of each fiscal year, or more frequently if events or changes in circumstances, such as a decline in sales, operations, or cash flows, or material adverse changes in the business climate, indicate that the carrying value of an asset might be impaired. The Company operates as a single reporting unit. In 2012, the Company adopted Accounting Standards Update (ASU) No. 2011-08, Intangibles—Goodwill and Other (Topic 350), Testing Goodwill for Impairment, that includes the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount before performing the two-step impairment test as required in Accounting Standards Codification (ASC) 350, Intangibles - Goodwill and Other. At September 30, 2014, the Company performed a qualitative goodwill impairment analysis. The September 30, 2014 impairment analysis included an assessment of certain qualitative factors including, but not limited to, overall financial performance, and macroeconomic and industry conditions. The Company considered the qualitative factors and weighed the evidence obtained, and determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. Although the Company believes the factors considered in the impairment analysis are reasonable, significant changes in any one of the assumptions used could produce a different result.

The Company examines on a periodic basis the carrying value of its long-lived tangible and intangible assets to determine whether there are any impairment losses. If indicators of impairment were present with respect to long-lived tangible and intangible assets used in operations and undiscounted future cash flows were not expected to be sufficient to recover the assets’ carrying amount, an impairment loss would be charged to expense in the period the impairment is identified based on the fair value of the asset less any costs of disposal. The Company believes no impairment exists as of September 30, 2014.

Revenue Recognition and Deferred Revenues

Revenues from cost sharing, cost-reimbursement (cost-type), fixed price and cost plus contracts with various government groups and agencies are recognized when the related costs are incurred and related services are performed. Contract costs primarily include direct labor, consultants, sub-contractors, materials, and other specific administrative costs related to the project. Deferred revenue represents amounts received in advance of services being performed and or delivery of products. Unbilled accounts receivable represents revenue recognized under the contracts in advance of billings.

Revenues from research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract, whether billed or unbilled. In many cases, the Company is reimbursed only a portion of the costs incurred or to be incurred on the contract. Revenues from government funded research, development and demonstration programs are generally multi-year, cost reimbursement and/or cost-shared type contracts or cooperative agreements. The Company is reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract agreements.

Notes to Consolidated Financial Statements

Revenues from product sales are recognized upon the delivery of units to customers, provided there is evidence that an arrangement exists, the fee is fixed or determinable, and collectability of the related receivable is probable. If there are acceptance provisions, revenue is recognized upon acceptance. Deferred revenue represents amounts received from customers in advance of shipments.

For the fiscal years ended September 30, 2014, 2013 and 2012, the Company had government and government-sponsored contract revenues of $6,329,386, $4,775,091 and $5,599,071 which represented approximately 97%, 93% and 93%, respectively, of total contract services revenue.

For the fiscal years ended September 30, 2014, 2013 and 2012, the Company had government and government-sponsored product revenues of $7,281,127, $7,207,107 and $3,755,242, respectively, which represented approximately 97%, 92% and 92%, respectively, of total product revenue.

In September 2013, the Company signed a development agreement related to the (Solid Oxide Fuel Cell) SOFC platform that was amended in June 2014, with additional deliverables and funding. The agreement includes the issuance of 1,132,200 warrants to purchase common stock that will be earned as milestone deliverables are met. The warrants will be issued upon customer payment for completion of milestones, and will be recorded as contra revenue based on their fair value on the date they are earned. As of September 30, 2013, no milestones were completed and no shares had vested. As of September 30, 2014, eight milestone payments were received and 841,200 shares had vested. The warrants have an exercise price of $0.01 per share and expire on September 30, 2020. During the year ended September 30, 2014, the Company recognized $246,714 as contra-revenue related to the fair value of the vested shares. (See Note 6).

Cost of Revenues

The Company had four significant suppliers in fiscal 2014, 2013 and 2012, which accounted for 76%, 64% and 66% of total purchases, respectively. Although only a limited number of suppliers have been used, other suppliers are available.

Income Taxes

Deferred income taxes have been recorded to recognize the estimated future tax consequences attributable to the cumulative temporary differences between financial statement and tax bases of assets and liabilities.

Deferred income tax assets and liabilities are computed for those differences that have a future tax consequence using currently enacted laws and rates that apply to periods in which they are expected to affect taxable income. Income tax expense is the current tax payable or refundable for the period plus or minus the net change in deferred tax asset and liability accounts. Valuation allowances are established, if necessary, to reduce a net deferred tax asset to the amount that will more likely than not be realized.

Research and Development Expense

Costs incurred in connection with research and development activities are expensed as incurred. These costs consist of direct and indirect costs associated with specific projects as well as fees paid to various third-party entities that perform certain research on behalf of the Company.

Warranty Expense

The Company offers basic limited parts and labor warranty on its hardware products. The basic warranty for power manager and cable products is two years from the date of purchase. Fuel cell products have a one year warranty from the date of purchase. The Company provides currently for the estimated costs that may be incurred under its basic limited product warranties at the time the related product revenue is recognized. Factors considered in determining the appropriate accruals for product warranty obligations include: historical and projected warranty claim rates, historical and projected cost-per-claim, and knowledge of specific product failures during development. The Company assesses the adequacy of its pre-existing warranty liabilities and adjust the amounts as necessary based on actual experience and changes in future estimates.

Stock-Based Compensation

The Company has a 2003 and a 2013 stock-based employee compensation plan. The Company follows the fair value recognition provisions of ASC No. 718, Stock Compensation (“ASC 718”). Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period.

The following table presents stock-based compensation expenses included in the Company’s Consolidated Statements of Operations:

Years ended September 30, |  | 2014 |  | 2013 |  | 2012 |
Research and development |  | $ | 63,811 |  | $ | 207,790 |  | $ | 286,906 |
Sales and marketing |  | 15,219 |  | 11,238 |  | 9,737 |
General and administrative |  | 99,027 |  | 59,764 |  | 127,894 |
Total Stock-Based Compensation Expense |  | $ | 178,057 |  | $ | 278,792 |  | $ | 424,537 |

At September 30, 2014, there is approximately $86,000 of unamortized stock-based compensation costs. That cost is expected to be recognized as expense over a weighted-average period of 1.5 years.

ASC 718 requires the benefits of tax deductions in excess of the compensation cost recognized for those options to be classified as financing cash inflows rather than operating cash inflows, on a prospective basis. The Company has fully reserved for any deferred tax benefits due to the uncertainty of future operating results and its ability to utilize the future tax benefit. As such, there is no effect on the Company’s Consolidated Statements of Cash Flows.

Notes to Consolidated Financial Statements

The fair value of each stock option was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

Years ended September 30, |  | 2014 |  | 2013 |  | 2012 |
Expected volatility |  | 79.0% |  | 79.0% |  | 79.0% |
Expected dividend yield |  | 0.0% |  | 0.0% |  | 0.0% |
Expected risk-free interest rate |  | 0.81% - 1.39% |  | 0.37% - 1.49% |  | .62% - .75% |
Expected term of options |  | 4.47 years |  | 4.47 years |  | 4.47 years |
Maximum contractual term |  | 10 years |  | 10 years |  | 10 years |
Estimated forfeitures |  | 20.0% |  | 21.0% |  | 20.0% |

Stock Price

Options issued during fiscal 2014, 2013 and 2012, were valued based on an independent valuation of the Company’s stock price.

Expected Volatility

Due to having minimal publicly traded experience of its stock, the Company utilized an expected volatility based on publicly available information as to the volatility of comparable traded companies in similar industries, development and size.

Expected Dividend Yield

The Company does not intend to pay dividends on its common stock for the foreseeable future and, accordingly, uses a dividend yield of zero in the Black-Scholes pricing model.

Expected Risk-Free Interest Rate

The risk-free interest rates for stock options are based on the US Treasury yield curve in effect at the time of grant for maturities, similar to the expected holding period of the stock options.

Expected Term

The expected term of stock options granted is generally based on historical data and represents the period of time that the stock options granted are expected to be outstanding. The Company has had very limited stock option exercise experience to date, making the Company’s determination of the “expected term” judgmental. Accordingly, the Company has based the expected term on publicly available information for companies in similar industries development and size.

Estimated Forfeitures

The Company has estimated employee stock option forfeitures as required under ASC 718 for two groups of stock options: (a) immediately vested options and (b) all others and is based on the Company’s limited experience. Estimated forfeitures are adjusted to actual forfeiture experience.

5. Intangible Assets

The following is a summary of intangible assets:

September 30, 2014 |  | Gross Carrying Amount |  | Accumulated Amortization |  | Net Carrying Value |  | Useful Life |
Core technology |  | $ | 555,000 |  | $ | 555,000 |  | $ | — |  | 6 years |
Other intangible assets |  | 184,000 |  | 176,550 |  | 7,450 |  | 5-6 years |
Total Intangible Assets |  | $ | 739,000 |  | $ | 731,550 |  | $ | 7,450 |  |  |

September 30, 2013 |  | Gross Carrying Amount |  | Accumulated Amortization |  | Net Carrying Value |  | Useful Life |
Core technology |  | $ | 555,000 |  | $ | 555,000 |  | $ | — |  | 6 years |

Total Intangible Assets |  | $ | 739,000 |  | $ | 714,954 |  | $ | 24,046 |  |  |

The Company amortizes intangible assets using the straight-line method over the above estimated useful lives of the respective intangible asset. The Company considers the straight-line method to be appropriate, as it approximates the pattern in which economic benefits are consumed in circumstances where such patterns can be reliably determined. During the years ended September 30, 2014, 2013 and 2012, amortization expense of intangible assets amounted to $16,596, $71,263 and $125,929 and is included in research and development expenses in the accompanying consolidated statements of operations. The remaining amount of $7,450 will be fully amortized in the fiscal year ending September 30, 2015.

6. Stockholders’ Equity

Stock Options

In June 2013, the Company’s shareholders approved the 2013 Stock Incentive Plan, which allows for the granting of incentive stock options (ISOs) and non-qualified stock options, stock appreciation rights, performance shares and restricted stock to employees, officers, Directors, advisors and consultants of the Company. The number of shares of the Company’s common stock that may be issued under the plan is 7,000,000 shares, and as of September 30, 2014, 6,092,000 shares remain available for future grant.

Notes to Consolidated Financial Statements

ISOs and non-qualified stock options under the 2003 Stock Incentive Plan, and has not issued any stock appreciation rights, performance shares or restricted stock.

In July 2009, the Board of Directors approved a provision in all existing and future stock option grants issued to employees and to future grants issued to Non-Executive Directors which provides that in the event of a future change in control of Protonex, the vesting of all outstanding stock options would be accelerated such that 50% of all unvested options would become vested upon the change of control. The acceleration of vesting would not shorten the overall vesting term of the options, but rather would provide that 50% of the options that would otherwise vest periodically over the entire vesting term would vest immediately upon the change in control.

A summary of the status of all of the Company’s stock options for the years ended September 30, 2014, 2013 and 2012 is presented below:

|  | Number of Shares |  | Weighted- Average Exercise Price Per Share |  | Weighted Average Remaining Contractual Life (Years) |

In September 2014, the Company received the remaining $0.5 million growth loan. The outstanding borrowings of $2.0 million at September 30, 2014 are secured by the Company’s accounts receivable, inventory and intellectual property. The agreement provided for an adjustable interest rate of prime plus 3.25% payable in cash, plus 3.25% interest that is capitalized, compounded and added to the unpaid principal of the term loan. Total capitalized interest of $165,350 was added to the unpaid principal balance as of September 30, 2014. The outstanding principal and capitalized interest is due and payable in March 2016.

9. Income Taxes

The provision for income taxes consists of the following:

Years ended September 30, |  | 2014 |  | 2013 |  | 2012 |
Current: |  |  |  |  |  |  |
State |  | $ | 456 |  | $ | 417 |  | $ | 150 |
Deferred: |  |  |  |  |  |  |
Federal |  | 177,185 |  | 185,898 |  | 177,641 |
State |  | 25,483 |  | 34,102 |  | 28,476 |
|  | 202,668 |  | 220,000 |  | 206,117 |
Total Provision for Income Taxes |  | $ | 203,124 |  | $ | 220,417 |  | $ | 206,267 |

A reconciliation of the expected income tax computed using the federal statutory income tax rate to the Company’s effective income tax rate is as follows:

Years ended September 30, |  | 2014 |  | 2013 |  | 2012 |
Federal statutory tax rate |  | (34 | )% | (34 | )% | (34 | )%
State taxes, net of federal benefit |  | (5 | ) | (4 | ) | (4 | )
Research and development tax credits |  | (29 | ) | (23 | ) | (11 | )
Non-cash compensation expense |  | 3 |  | 5 |  | 6 |
Other differences |  | (11 | ) | (8 | ) | (9 | )
Change in valuation allowance |  | 98 |  | 78 |  | 63 |
Effective Tax Rate |  | 22 | % | 14 | % | 11 | %

The Company has approximately $55,437,000 of net operating loss carryforwards (NOLs) for federal income tax purposes and approximately $13,880,000 of NOLs for state income tax purposes at September 30, 2014. The federal NOLs will begin to expire in the year 2023 if not utilized. The available state NOLs began to expire in 2013. The Company has approximately $2,911,000 of tax credit carryforwards for federal income tax purposes and approximately $1,708,000 of tax credit carryforwards for state income tax purposes at September 30, 2014. The federal tax credits begin to expire in 2020 and the state tax credits begin to expire in 2021. Under the Internal Revenue Code, certain substantial changes in the Company’s ownership may result in an annual limitation on the amount of NOL and tax credit carryforwards, which may be utilized in future years.

Included in the above NOLs is approximately $492,000 resulting from excess tax deductions from stock options exercised during the year ended September 30, 2006. Pursuant to ASC 718, the deferred tax asset relating to excess tax benefit from these exercises was not recognized for financial statement purposes. The asset will be recorded as a credit to additional paid in capital to the extent the Company receives a cash savings in the future.

F-22

Notes to Consolidated Financial Statements

Included in the above NOLs is approximately $386,000, $339,000 and $292,000 of excess tax goodwill NOLs carryforwards for the years ended September 30, 2014. 2013 and 2012, respectively. The deferred tax asset relating to the excess tax benefit from the goodwill amortization was not recognized for financial statement purposes. The benefit will be recorded when the Company receives the cash benefit in the future.

The Company’s deferred tax liabilities are created by goodwill as a result of a prior acquisition. In accordance with ASC 350, deferred tax liabilities resulting from the different treatment of goodwill for book and tax purposes cannot offset deferred tax assets in determining the valuation allowance. As a result, a deferred tax provision is required to increase the Company’s valuation allowance. The deferred tax liability as a result of the goodwill associated with the prior acquisition as of September 30, 2014 and 2013 is $1,528,261 and $1,325,137, respectively. For tax purposes, goodwill generated from the acquisition amounted to $8,521,000 and is deductible over a 15-year period.

Due to the uncertainty of future operating results, management believes it to be more likely than not that the gross deferred tax assets will not be realized; therefore, a full valuation allowance against such assets has been recorded at September 30, 2014 and 2013.

The primary temporary differences that give rise to the deferred tax asset and liability are NOL carryforwards, non-deductible reserves and accruals and differences in bases of the tangible and intangible assets. The income tax effects of these temporary differences are as follows:

September 30, |  | 2014 |  | 2013 |
Net operating loss carryforwards |  | $ | 19,264,291 |  | $ | 19,479,264 |
Credits |  | 4,037,470 |  | 3,011,413 |
Stock options |  | 777,806 |  | 745,290 |
Depreciation and amortization |  | 427,667 |  | 441,558 |
Other temporary differences |  | 150,264 |  | 228,302 |
Gross deferred tax asset |  | 24,657,498 |  | 23,905,827 |
Less: valuation allowance |  | 24,657,498 |  | 23,905,827 |
Net deferred tax assets |  | $ | — |  | $ | — |
Deferred tax liabilities: |  |  |  |  |
Tax goodwill amortization |  | $ | 1,528,261 |  | $ | 1,325,137 |

The Company follows the provisions of ASC 740, “Accounting for Uncertainty in Income Taxes”. As of September 30, 2014, the total amount of net unrecognized tax benefit was approximately $673,000 which would be recorded with an offsetting adjustment to the Company’s valuation allowance. There has been no significant change in the unrecognized tax benefit since adoption.

The Company did not recognize any accrued interest and penalties related to unrecognized tax benefits as no amounts would be due as a result of the net tax loss carryforward. The Company’s policy is to record interest and penalties related to unrecognized tax benefits in income tax expense. All tax years remain subject to examination by the taxing authorities for both Federal and state purposes. The primary state jurisdiction is the Commonwealth of Massachusetts.

The Company follows the provisions of ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) for fair value measurements of financial assets and financial liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a non-recurring basis. ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 inputs are unobservable inputs for the asset or liability.

The Level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety.

As of September 30, 2014 and 2013, the Company’s money market funds of $95,195 and $95,174, respectively, were valued using quoted prices generated by market transactions involving identical assets, or Level 1 assets as defined under ASC 820.

The Company evaluated all events or transactions that occurred after September 30, 2014 through December 8, 2014, the date these financial statements were available to be issued. All material subsequent events have been disclosed in the financial statements except as noted below as to which the date is June 29, 2015.

In May 2015, the Company secured a $2.0 million working capital line of credit with a bank. Outstanding borrowings were secured by the Company’s accounts receivable and inventory. The bank has a senior blanket lien on all Company assets, including IP. The agreement provided for an adjustable interest rate of prime plus 2.5% or 1.5%, depending on balance sheet liquidity ratios.

On June 29, 2015, the Company entered into a definitive agreement with Ballard Power Systems, Inc. (Ballard). Pursuant to a merger agreement in which the Company will merge with Ballard, Ballard will acquire all of the securities of the Company, including all outstanding shares of common stock and all outstanding and vested options and warrants to purchase shares of Company common stock. The purchase price (enterprise value) of US $30 million will be paid in shares of Ballard common stock and cash.

Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Organization and Basis of Presentation

Organization

Protonex Technology Corporation (the “Company”) was incorporated in October 2000, and performs engineering and development on fuel cell technology under cost sharing, cost-reimbursement (cost-type), fixed price and cost plus contracts. In addition, the Company assembles and sells related products. The Company is headquartered in Southborough, Massachusetts, and its primary market has been government agencies of the United States of America.

These consolidated financial statements have been prepared on a going concern basis. As such, they anticipate the realization of assets and the liquidation of liabilities in the normal course of business. The Company incurred net losses of $581,253 and $1,058,962 for the three and six months ended March 31, 2015, respectively, and has an accumulated deficit of $63,153,514 as of March 31, 2015. The Company has funded these losses principally through equity financings, government contracts and a growth line of credit. Management believes that its government contract business, product sales growth, partnering with others and cash on hand, will be adequate to fund operations for at least twelve months from the date these financial statements were issued.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates and judgments on historical experience and on various other factors that are considered reasonable under the circumstances. Actual results could differ materially from these estimates.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Protonex Technology, LLC. All material intercompany transactions and balances have been eliminated in consolidation.

Fair Value of Financial Instruments

The carrying amounts of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, capital leases, accrued liabilities and long-term debt approximate their fair values due to the short-term nature of these instruments or their market rates of interest.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Similarly, all money market accounts are considered cash equivalents.

The Company maintains its cash in bank deposit accounts, which, at times, may exceed federally insured limits, and in high quality, short-term, highly liquid investment securities. At March 31, 2015, $425,128 of cash equivalents exceed federally insured limits. Of the cash equivalents, $95,204 is maintained in a money-market fund that invests primarily in US Treasury Bills and the remaining balance is in a savings account. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk.

Accounts Receivable

Accounts receivable are stated at the amount management expects to collect from outstanding balances. The Company reviews accounts receivable on a monthly basis to determine if any receivables will potentially be uncollectible. Management provides for uncollectible amounts through a charge to operations and a credit to a valuation allowance based on its assessment. Based on experience, the Company does not record a reserve against the receivables from the agencies/groups of the United States Government. As of March 31, 2015 and September 30, 2014, 3% and 10%, respectively, of accounts receivable were from various government agencies. Government agencies and customers with government agencies as end user customers account for 87% and 93% of total accounts receivable at March 31, 2015 and September 30, 2014, respectfully.

Inventories and Related Allowance for Obsolete and Excess Inventory

Inventories consist primarily of raw materials and are recorded at the lower of cost or market. Cost is determined on a first-in, first-out basis. Reserves are recorded for slow moving, obsolete, non-sellable or unusable items and were approximately $164,000 at March 31, 2015 and September 30, 2014.

Property and Equipment

Property and equipment are recorded at cost and are depreciated using the straight-line method over their expected useful lives. Construction in progress represents fixed assets not yet placed in service, that at completion are transferred to the appropriate fixed asset category and depreciated on a straight-line basis over estimated useful lives of three - five years or remaining lease terms.

The current useful lives are:

Assets |  | Estimated Useful Lives
Furniture, fixtures and equipment |  | 5 years
Computer hardware and software |  | 3 - 5 years
Equipment under capital leases |  | 5 years
Leasehold improvements |  | Lesser of useful life or remaining lease term

Goodwill

The Company evaluates the recoverability of goodwill and intangible assets with indefinite useful lives as of the end of each fiscal year, or more frequently if events or changes in circumstances, such as a decline in sales, operations, or cash flows, or material adverse changes in the business climate, indicate that the carrying value of an asset might be impaired. The Company operates as a single reporting unit. In 2012, the Company adopted Accounting Standards Update (ASU) No. 2011-08, Intangibles—Goodwill and Other (Topic 350), Testing Goodwill for Impairment, that includes the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount before performing the two-step impairment test as required in Accounting Standards Codification (ASC) 350, Intangibles - Goodwill and Other. At September 30, 2014, the Company performed a qualitative goodwill impairment analysis. The September 30, 2014 impairment analysis included an assessment of certain qualitative factors including, but not limited to, overall financial performance, and macroeconomic and industry conditions. The Company considered the qualitative factors and weighed the evidence obtained, and determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying amount. Although the Company believes the factors considered in the impairment analysis are reasonable, significant changes in any one of the assumptions used could produce a different result. There were no triggering events during the period ended March 31, 2015 that caused the Company to reassess its annual assessment.

Impairment of Long-Lived Tangible and Intangible Assets

The Company examines on a periodic basis the carrying value of its long-lived tangible and intangible assets to determine whether there are any impairment losses. If indicators of impairment were present with respect to long-lived tangible and intangible assets used in operations and undiscounted future cash flows were not expected to be sufficient to recover the assets’ carrying amount, an impairment loss would be charged to expense in the period the impairment is identified based on the fair value of the asset less any costs of disposal.

Revenue Recognition and Deferred Revenues

Revenues from cost sharing, cost-reimbursement (cost-type), fixed price and cost plus contracts with various government groups and agencies are recognized when the related costs are incurred and related services are performed. Contract costs primarily include direct labor, consultants, sub-contractors, materials, and other specific administrative costs related to the project. Deferred revenue represents amounts received in advance of services being performed and or delivery of products. Unbilled accounts receivable represents revenue recognized under the contracts in advance of billings.

Revenues from research and development contracts are recognized proportionally as costs are incurred and compared to the estimated total research and development costs for each contract, whether billed or unbilled. In many cases, the Company is reimbursed only a portion of the costs incurred or to be incurred on the contract. Revenues from government funded research, development and demonstration programs are generally multi-year, cost reimbursement and/or cost-shared type contracts or cooperative agreements. The Company is reimbursed for reasonable and allocable costs up to the reimbursement limits set by the contract agreements.

Revenues from product sales are recognized upon the delivery of units to customers, provided there is evidence that an arrangement exists, the fee is fixed or determinable, and collectability of the related receivable is probable. If there are acceptance provisions, revenue is recognized upon acceptance. Deferred revenue represents amounts received from customers in advance of shipments.

For the three and six months ended March 31, 2015, the Company had government and government-sponsored contract revenues of $1,200,190 and $2,421,291, respectively, which represented approximately 82% and 91%, respectively, of total contract services revenue.

For the three and six months ended March 31, 2015, the Company had government and government-sponsored product revenues of $985,935 and $2,918,773, respectively, which represented approximately 79% and 95%, respectively, of total product revenue.

For the three and six months ended March 31, 2014, the Company had government and government-sponsored contract revenues of $1,670,681 and $3,138,725, respectively, which represented approximately 100% and 95%, respectively, of total contract services revenue.

For the three and six months ended March 31, 2014, the Company had government and government-sponsored product revenues of $1,307,469 and $3,041,553, respectively, which represented approximately 90% and 95%, respectively, of total product revenue.

In September 2013, the Company signed a development agreement related to the Solid Oxide Fuel Cell (SOFC) platform that was amended in June 2014, with additional deliverables and funding. The agreement includes the issuance of 1,132,200 warrants to purchase common stock that will be earned as milestone deliverables are met. The warrants will be issued upon customer payment for completion of milestones, and will be recorded as contra revenue based on their fair value on the date they are earned. As of March 31, 2015 and September 30, 2014, eleven and eight, respectively, milestones payments were received and 976,200 and 841,200, respectively, warrants had vested. The warrants have an exercise price of $0.01 per share and expire on September 30, 2020. During the three and six months ended March 31, 2015, the Company recognized $0 and $39,609, respectively, as contra-revenue related to the fair value of the vested warrants. During the three and six months ended March 31, 2014, the Company recognized $139,044 and $139,044, respectively, as contra-revenue related to the fair value of the vested warrants.

Cost of Revenues

For the three and six months ended March 31, 2015, the Company had four significant suppliers which accounted for 51% and 71%, respectively, of total purchases. For the three and six months ended March 31, 2014, the same four suppliers accounted for 36% and 48%, respectively, of total purchases. Although only a limited number of suppliers have been used, other suppliers are available.

Income Taxes

Deferred income taxes have been recorded to recognize the estimated future tax consequences attributable to the cumulative temporary differences between financial statement and tax bases of assets and liabilities.

F-33

Table of Contents

Notes to Condensed Consolidated Financial Statements

(unaudited)

Deferred income tax assets and liabilities are computed for those differences that have a future tax consequence using currently enacted laws and rates that apply to periods in which they are expected to affect taxable income. Income tax expense is the current tax payable or refundable for the period plus or minus the net change in deferred tax asset and liability accounts. Valuation allowances are established, if necessary, to reduce a net deferred tax asset to the amount that will more likely than not be realized.

The Company’s deferred tax liabilities are created by goodwill as a result of a prior acquisition. In accordance with Accounting Standards Codification (ASC) 350, deferred tax liabilities resulting from the different treatment of goodwill for book and tax purposes cannot offset deferred tax assets in determining the valuation allowance. As a result, a deferred tax provision is required to increase the Company’s valuation allowance. The deferred tax liability as a result of the goodwill associated with a prior acquisition as of March 31, 2015 and September 30, 2014 is $1,630,261 and $1,528,261, respectively. For tax purposes, goodwill generated from the acquisition amounted to $8,521,000 and is deductible over a 15-year period.

During the three and six month periods ending March 31, 2015, the Company continued to incur operating losses and due to the uncertainty of future operating results, management believes it to be more likely than not that the gross deferred tax assets will not be realized; therefore, a full valuation allowance against such assets has been recorded at March 31, 2015 and September 30, 2014, respectively.

Research and Development Expense

Costs incurred in connection with research and development activities are expensed as incurred. These costs consist of direct and indirect costs associated with specific projects as well as fees paid to various third-party entities that perform certain research on behalf of the Company.

Warranty Expense

The Company offers basic limited parts and labor warranty on its hardware products. The basic warranty for power manager and cable products is two years from the date of purchase. Fuel cell products have a one year warranty from the date of purchase. The Company provides currently for the estimated costs that may be incurred under its basic limited product warranties at the time the related product revenue is recognized. Factors considered in determining the appropriate accruals for product warranty obligations include: historical and projected warranty claim rates, historical and projected cost-per-claim, and knowledge of specific product failures during development. The Company assesses the adequacy of its pre-existing warranty liabilities and adjust the amounts as necessary based on actual experience and changes in future estimates.

Stock-Based Compensation

The Company has a 2003 and a 2013 stock-based employee compensation plan. The Company follows the fair value recognition provisions of ASC No. 718, Stock Compensation (“ASC 718”). Under the fair value recognition provisions of ASC 718, stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the service period.

The following table presents stock-based compensation expenses included in the Company’s consolidated condensed statements of operations:

General and administrative |  | 43,116 |  | 32,794 |
Total Stock-Based Compensation Expense |  | $ | 87,628 |  | $ | 77,468 |

At March 31, 2015, there is approximately $405,000 of unamortized stock-based compensation costs. That cost is expected to be recognized as expense over a weighted-average period of 2.4 years.

ASC 718 requires the benefits of tax deductions in excess of the compensation cost recognized for those options to be classified as financing cash inflows rather than operating cash inflows, on a prospective basis. The Company has fully reserved for any deferred tax benefits due to the uncertainty of future operating results and its ability to utilize the future tax benefit. As such, there is no effect on the Company’s Consolidated Statements of Cash Flows.

The fair value of each stock option was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions:

Three and Six Months Ended March 31, |  | 2015 |  | 2014 |
Expected volatility |  | 75.0% |  | 79.0% |

Stock Price

Options issued during the three and six months ended March 31, 2015 were valued based on an independent valuation of the Company’s stock price.

Expected Volatility

Due to having minimal publicly traded experience of its stock, the Company utilized an expected volatility based on publicly available information as to the volatility of comparable traded companies in similar industries, development and size.

Expected Dividend Yield

The Company does not intend to pay dividends on its common stock for the foreseeable future and, accordingly, uses a dividend yield of zero in the Black-Scholes pricing model.

Expected Risk-Free Interest Rate

The risk-free interest rates for stock options are based on the US Treasury yield curve in effect at the time of grant for maturities, similar to the expected holding period of the stock options.

Expected Term

The expected term of stock options granted is generally based on historical data and represents the period of time that the stock options granted are expected to be outstanding. The Company has had very limited stock option exercise experience to date, making the Company’s determination of the “expected term” judgmental. Accordingly, the Company has based the expected term on publicly available information for companies in similar industries development and size.

Estimated Forfeitures

The Company has estimated employee stock option forfeitures as required under ASC 718 for two groups of stock options: (a) immediately vested options and (b) all others and is based on the Company’s limited experience. Estimated forfeitures are adjusted to actual forfeiture experience.

3. Stock Option Activity

In June 2013, the Company’s shareholders approved the 2013 Stock Incentive Plan, which allows for the granting of incentive stock options (ISOs) and non-qualified stock options, stock appreciation rights, performance shares and restricted stock to employees, officers, Directors, advisors and consultants of the Company. The number of shares of the Company’s common stock that may be issued under the plan is 7,000,000 shares, and as of March 31, 2015, 1,420,000 shares remain available for future grant. To date, the Company has issued ISOs and non-qualified stock options under the 2013 Stock Incentive Plan, and has not issued any stock appreciation rights, performance shares or restricted stock.

In July 2009, the Board of Directors approved a provision in all existing and future stock option grants issued to employees and to future grants issued to Non-Executive Directors which provides that in the event of a future change in control of Protonex, the vesting of all outstanding stock options would be accelerated such that 50% of all unvested options would become vested upon the change of control. The acceleration of vesting would not shorten the overall vesting term of the options, but rather would provide that 50% of the options that would otherwise vest periodically over the entire vesting term would vest immediately upon the change in control.

A summary of the status of all of the Company’s stock options for the six month period ended March 31, 2015 is presented below:

|  | Number of Shares |  | Weighted- Average Exercise Price Per Share |  | Weighted Average Remaining Contractual Life (Years) |
Outstanding — September 30, 2014 |  | 8,749,591 |  | $ | 0.21 |  | 6.16 |
Granted |  | 4,672,000 |  | 0.15 |  |  |
Exercised |  | (17,000 | ) | 0.08 |  |  |
Forfeited/cancelled |  | (27,497 | ) | 0.28 |  |  |
Outstanding — March 31, 2015 |  | 13,377,094 |  | $ | 0.19 |  | 7.07 |
Exercisable — March 31, 2015 |  | 8,893,938 |  | $ | 0.20 |  | 5.77 |

Growth Loan & Credit Facilities

In March 2013, the Company secured a $2.0 million growth loan with an investment firm that provided for an initial term loan of $1.5 million with an additional $0.5 million available for subsequent use. In September 2014, the Company received the remaining $0.5 million growth loan. The outstanding borrowings of $2.0 million at March 31, 2015 are secured by the Company’s accounts receivable, inventory and intellectual property. The agreement provided for an adjustable interest rate of prime plus 3.25% payable in cash, plus 3.25% interest that is capitalized, compounded and added to the unpaid principal of the term loan. Total capitalized interest of $261,646 was added to the unpaid principal balance as of March 31, 2015. The outstanding principal and capitalized interest is due and payable in March 2016. The Company is required to maintain certain financial covenants under the growth loan. On March 30, 2015, the Company signed an amendment to the loan that adjusted loan covenants. As of March 31, 2015, the Company is in compliance with such covenants.

The Company issued 560,000 warrants to purchase common stock to the lender in connection with the growth loan. The warrants have an exercise price of $0.01 per share and expire on March 8, 2020. The fair value of the warrants was determined to be $173,349 and was recorded as a debt discount and is being amortized as additional interest expense over the term of the loan. Total amortization of the discount during the three and six months ended March 31, 2015 was $14,137 and $28,243, respectively. Total amortization of the discount during the three and six months ended March 31, 2014 was $16,103 and $32,040, respectively.

Litigation

From time to time, the Company is a party to various legal proceedings incidental to its business. The Company believes that none of the legal proceedings, that are presently pending, if adversely decided against the Company, will have a material adverse effect upon its financial position, results of operations, or liquidity.

6. Employee Retirement Plan

The Company adopted a 401(k) plan effective January 1, 2005. The plan is an employee deferral based pre-tax retirement plan. The Company can elect to make discretionary matching contributions into the plan. To date, the Company has not made a discretionary matching contribution.

7. Related Parties

The Company has a relationship with CBC America Corporation (“CBC”), a shareholder in the Company. CBC also facilitates purchases by the Company of components for fuel cell development from international suppliers. Effective as of July 2008, the Company entered into an agreement with CBC and another party to jointly develop certain products. During the three and six months ended March 31, 2015, the Company had purchases from CBC of $27,795 and $27,795, respectively. During the three and six months ended March 31, 2014, the Company had purchases from CBC of $18,530 and $65,150, respectively.

8. Fair Value Measurements

The Company follows the provisions of ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) for fair value measurements of financial assets and financial liabilities that are recognized or disclosed at fair value in the consolidated financial statements on a recurring basis and non-financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a non-recurring basis. ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities

F-38

Table of Contents

(unaudited)

(Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 inputs are unobservable inputs for the asset or liability.

The Level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety.

As of March 31, 2015 and September 30, 2014, the Company’s money market funds of $95,204 and $95,195, respectively, were valued using quoted prices generated by market transactions involving identical assets, or Level 1 assets as defined under ASC 820.

9. Subsequent Events

In May 2015, the Company secured a $2.0 million working capital line of credit with a bank. Outstanding borrowings were secured by the Company’s accounts receivable and inventory. The bank has a senior blanket lien on all Company assets, including Intellectual Property. The agreement provided for an adjustable interest rate of prime plus 2.5% or 1.5%, depending on balance sheet liquidity ratios.

On June 29, 2015, the Company entered into a definitive agreement with Ballard Power Systems, Inc. (Ballard). Pursuant to a merger agreement in which the Company will merge with Ballard, Ballard will acquire all of the securities of the Company, including all outstanding shares of common stock and all outstanding and vested options and warrants to purchase shares of Company common stock. The purchase price (enterprise value) of US $30 million will be paid in shares of Ballard common stock and cash.

The Company evaluated all events or transactions that occurred after March 31, 2015 through June 29, 2015, the date these financial statements were available to be issued. All material subsequent events have been disclosed in the financial statements.

(c) Exchange Procedures.

(i) As promptly as practicable following the Effective Time (but in no event later than three (3) Business Days thereafter), the Surviving Corporation shall cause the Exchange Agent to mail to each holder of record of any shares of Company Common Stock (A) a letter of transmittal (a “Letter of Transmittal”) in the form reasonably satisfactory to the Company, Parent and the Exchange Agent (which shall be based on the Exchange Agent’s standard form and will include additional representations, warranties, releases and covenants consistent with those contained in the Support Agreement), which shall specify that delivery shall be effected, and risk of loss and title to the certificates representing such Company Common Stock (each a “Certificate”) shall pass, only upon proper delivery of such certificates (or affidavits of loss in lieu thereof as provided in Section 1.4.(f) below) to the Exchange Agent, and (B) instructions for use in effecting the surrender of such Certificates in exchange for the aggregate number of shares of Parent Common Stock issued in book-entry form (rounded down to the nearest whole share of Parent Common Stock after aggregating all shares of Parent Common Stock which such Company Stockholder is entitled to receive hereunder) to be issued in respect of such shares of Company Common Stock pursuant to Section 1.6 hereof and as set forth on the Closing Consideration Schedule.

(ii) Upon surrender of a Certificate (or affidavit of loss in lieu thereof) to the Exchange Agent, together with a Letter of Transmittal duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent, the Exchange Agent shall issue to the holder of such Certificate that number of uncertificated shares of Parent Common Stock that such Holder is entitled to receive pursuant to Section 1.6 and as set forth on the Closing Consideration Schedule. Prior to accepting any Certificates, the Exchange Agent may require compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with customary exchange practices. Until surrendered as contemplated by this Section 1.4.(c) each Certificate shall be deemed, at any time after the Effective Time, to represent only the right to receive, upon such surrender, the applicable consideration as contemplated by this Article I subject to compliance with the terms of this Agreement. No interest shall be paid or accrued for the benefit of holders of the Certificates on the applicable consideration payable upon the surrender of the Certificates hereunder.

(iii) In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer records of the Company, it shall be a condition of payment that any Certificate surrendered in accordance with the procedures set forth in this Section 1.4.(c) shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer Taxes and other Taxes required by reason of the payment of the applicable consideration pursuant to Section 1.6 and as set forth on the Closing Consideration Schedule to a Person other than the registered holder of the Certificate and shall have established to the reasonable satisfaction of Parent that such Tax either has been paid or is not applicable.

(d) No Further Ownership Rights in Company Common Stock. At and after the Effective Time, each holder of issued and outstanding Company Common Stock immediately prior to the Effective Time shall cease to have any rights as a holder of securities of the Company, except for the right of a Company Stockholder to surrender its, his or her Certificate(s) in exchange for the consideration payable in respect of such Company Common Stock hereunder and such holder’s share, if any, of any distributions of amounts held in escrow pursuant to Section 1.11 hereof, or in the case of a Dissenting Stockholder, to perfect its, his or her right to receive payment (if any) for Dissenting Shares pursuant to the DGCL, if applicable. After the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Company Common Stock outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in (and subject to compliance with the provisions of) this Article I, except as otherwise provided by Law.

Table of Contents

(e) No Fractional Shares. No fractional shares of Parent Common Stock shall be issued in connection with the Merger.

(f) Lost, Stolen or Damaged Stock Certificates. In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if reasonably required by Parent or the Exchange Agent, the delivery by such Person of an indemnification agreement in such form and containing such substance acceptable to Parent and the Exchange Agent and, if required by the Exchange Agent, the posting of a bond in such amount as the Exchange Agent may determine reasonably necessary as indemnity against any claim that may be made with respect to such Certificate, the Exchange Agent will pay in exchange for such lost, stolen or destroyed Certificate the consideration to be paid with respect thereto, subject to the terms and conditions in this Article I.

(g) Withholding Taxes. Parent, the Surviving Corporation, the Exchange Agent and the Escrow Agent shall be entitled to deduct and withhold (or cause to be deducted and withheld) from the consideration otherwise payable pursuant to this Agreement (including consideration held in escrow pursuant to Section 1.11) to any Company Stockholder or other Person such amounts as may be required to be deducted and withheld with respect to the making of such payment under the Code or under any provision of state, local or foreign Tax law. To the extent that amounts are so deducted and withheld and paid over to the appropriate Tax Authority, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. For the avoidance of doubt, nothing in this Section 1.4(g) shall limit the Company’s ability and obligation to withhold any Taxes in connection with the exercise of vested Company Options by a holder at or prior to the Closing, including by requiring such holder to pay the Company cash in an amount equal to any applicable withholding Taxes.

1.5. Subsequent Actions. If at any time after the Effective Time the Surviving Corporation shall determine, in its sole discretion, or shall be advised, that any deeds, bills of sale, instruments of conveyance, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of the Company acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, then the officers and directors of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of the Company, all such deeds, bills of sale, instruments of conveyance, assignments and assurances and to take and do, in the name and on behalf of the Company or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title or interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out this Agreement.

1.6. Conversion of Securities.

(a) Effect on Company Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of shares of Company Common Stock, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than any (A) Dissenting Shares and (B) Treasury Shares) will be cancelled and will be converted automatically into the right to receive upon surrender of the applicable Certificate representing such shares of Company Common Stock in the manner provided in Section 1.4 hereof, upon the terms and subject to the conditions set forth in this Section 1.6 and throughout this Agreement, including the escrow provisions set forth in Section 1.11 and Article VII hereof, the Per Share Common Consideration.

Change in Recommendation and/or (ii) terminate this Agreement pursuant to Section 8.1(and concurrently with such termination cause Company to enter into a definitive agreement with respect to the Superior Proposal), in each case of clauses (i) or (ii), if the Board of Directors of the Company has determined in good faith, after consulting with its outside counsel, that the failure to take such action would be a breach of the directors’ fiduciary duties under applicable Law; provided that the board of directors may not take any such action in connection with an Acquisition Proposal unless (1) the board of directors has determined that such Acquisition Proposal constitutes a Superior Proposal, (2) prior to terminating this Agreement pursuant to Section 8.1, Company provides prior written notice to Parent at least four Business Days in advance (the “Notice Period”) of its intention to take such action, which notice shall specify all material terms and conditions of such Superior Proposal (including the identity of the party making such Superior Proposal and copies of any documents or correspondence evidencing such Superior Proposal), and any material modifications to any of the foregoing (it being agreed that any modification to the terms and conditions of such Superior Proposal shall require a new written notice and a new four Business Day Notice Period), (3) during the Notice Period Company shall, and shall cause its financial advisors and outside counsel to negotiate with Parent in good faith should Parent propose to make such adjustments in the terms and conditions of this Agreement so that such Superior Proposal ceases to constitute (in the good faith judgment of Company’s Board of Directors) a Superior Proposal and (4) such Superior Proposal continues to constitute (in the good faith judgment of Company’s Board of Directors) a Superior Proposal after taking into account any such amendments that Parent shall have agreed to make prior to the end of the Notice Period.

The Company Stockholders shall provide Parent with evidence satisfactory to Parent that such Transfer Taxes have been paid by the Company Stockholders. If Parent or any of its Affiliates pays any Transfer Taxes for which the Company Stockholders are responsible under this Section 5.7.(f), Parent shall be entitled to recover out of the Escrow Account an amount equal to such Transfer Taxes in the manner set forth in Section 7.3 hereof and, if necessary, the Company Stockholders shall indemnify Parent for such amount to the extent provided in Article VI.

The Company shall also take such

A-52

other reasonable actions in furtherance of the termination of each 401(k) Plan as Parent may reasonably require.

(b) The parties acknowledge that the transactions contemplated under this Agreement shall not, by themselves, constitute a termination of employment of any employee of the Company.

Prior to the Closing, if a 280G Vote is required, the Company shall deliver to Parent evidence reasonably satisfactory to Parent, (i) that a 280G Vote was solicited in conformance with Section 280G of the Code, and the requisite stockholder approval was obtained with respect to any payments and/or benefits that were subject to the Company stockholder vote (the “Section 280G Approval”) or (ii) that the Section 280G Approval was not obtained and as a consequence, pursuant to the Parachute Payment Waiver, such “parachute payments” shall not be made or provided. The form of the Parachute Payment Waiver, the disclosure statement, any other materials to be submitted to the Company’s shareholders in connection with the Section 280G Approval and the calculations related to the foregoing (the “Section 280G Soliciting Materials”) shall be subject to advance review and approval by Parent, which approval shall not be unreasonably withheld.

(d) Nothing in this Agreement shall, or shall be construed so as to (a) prevent or restrict in any way the right of Parent to terminate, reassign, promote or demote any employee, independent contractor, manager or other service provider of the Company (or to cause any of the foregoing actions) at any time, or to change (or cause the change of) the title, powers, duties, responsibilities, functions, locations, salaries, other compensation or terms or conditions of employment or service of any such service providers; (b) create any third-party rights in any such current or former service provider of the Company (or any beneficiaries or dependents thereof); (c) constitute an amendment or modification of any Plan, or (d) obligate Parent or any of its Affiliates to adopt or maintain any Plan or other compensatory or benefits arrangement at any time or prevent Parent or any of its Affiliates from modifying or terminating any Plan or any other compensatory or benefits arrangement at any time.

5.9. Preparation of F-4 and Stockholder Meeting.

Each of the Company and Parent shall use its reasonable efforts to (i) have the Form F-4 declared effective under the Securities Act as promptly as practicable after such filing, (ii) ensure that the Form F-4 complies in all material respects with the applicable provisions of the Exchange Act or Securities Act and (iii) keep the Form F-4 effective for so long as necessary to complete the Merger.

Parent and the Company shall use their reasonable efforts to respond as promptly as practicable to any comments or requests for additional information from the SEC with respect to the Form F-4. Parent shall advise the Company, promptly after it receives notice thereof, of any comments or requests for additional information from the SEC with respect to the Form F-4 or the time of effectiveness of the Form F-4.

(b) If, at any time prior to the receipt of the Company Stockholder Approval, any information relating to the Company or Parent, or any of their respective Affiliates, should be discovered by the Company or Parent which, in the reasonable judgment of the Company or Parent, should be set forth in an amendment of, or a supplement to, the Form F-4 or the Proxy Statement, so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto, and the Company and Parent shall cooperate in the prompt filing with the SEC of any necessary amendment of, or supplement to, the Form F-4 or Proxy Statement, as applicable, and, to the extent required by Law, in disseminating the information contained in such amendment or supplement to Company Stockholders and stockholders of Parent. For purposes of Section 3.28, Section 4.7 and this Section 5.9.(b), any information concerning or related to the Company, its Affiliates or the Company Stockholder Meeting will be deemed to have been provided by the Company, and any information concerning or related to Parent or its Affiliates will be deemed to have been provided by Parent.

(c) As promptly as practicable after the date of this Agreement, the Company shall, in accordance with applicable Law and the Company Charter and the Company Bylaws, establish a record date for, duly call, give notice of, convene and hold a meeting of the stockholders of the Company to obtain the Company Stockholder Approval (the “Company Stockholder Meeting”). The Company shall, through the Company’s Board of Directors, recommend to the Company Stockholders that they give the Company Stockholder Approval (the “Company Board Recommendation”) and use its reasonable best efforts to obtain the Company Stockholder Approval, except as and to the extent expressly permitted by Section 5.3 (a “Change in Recommendation”). Notwithstanding any Change in Recommendation, the Company shall submit this Agreement to the Company Stockholders for their consideration at the Company Stockholder Meeting and nothing in this Agreement shall relieve Company of the obligation to do so. In the event that there is present at such Company Stockholder Meeting, in person or by proxy, sufficient favorable voting power to secure the Company Stockholder Approval, the Company will not adjourn or postpone the Company Stockholder Meeting unless the Company is advised by counsel that failure to do so would result in a breach of the fiduciary duties of the Company’s Board of Directors. The Company shall use reasonable best efforts to cause the Proxy Statement to be mailed to the Company Stockholders as promptly as practicable after the Form F-4 is declared effective under the Securities Act. Notwithstanding the foregoing provisions of this Section 5.9, if, on a date for which the Company Stockholder Meeting is scheduled, the Company has not received proxies representing a sufficient number of shares of Company Common Stock to obtain the Company Stockholder Approval, whether or not a quorum is present, the Company shall have the right to make one or more successive postponements or adjournments of the Company Stockholder Meeting; provided, that, the Company Stockholder Meeting is not postponed or adjourned to a date on or after the Outside Date. Unless this Agreement is terminated in accordance with Section 8.1, nothing contained in this Agreement shall be deemed to relieve the Company of its obligation to submit the approval of the Merger Agreement to its stockholders for a vote on the approval thereof.

Each of the Company Stockholders, severally and not jointly, shall indemnify, save and hold harmless Parent, Merger Sub, the Company and each of Parent’s direct and indirect stockholders, Affiliates and Subsidiaries (including, following the Closing, the Surviving Corporation), and each of their respective Representatives (collectively, the “Parent Indemnitees”), from and against any and all costs, losses, Taxes, Liabilities, obligations, damages, lawsuits, deficiencies, claims, demands, expenses (whether or not arising out of third-party claims), reasonable attorneys’ fees and all amounts paid in investigation, defense or settlement of any of the foregoing (herein, “Damages”), incurred in connection with, arising out of, resulting from or incident to (i) any breach of any representation or warranty or the inaccuracy of any representation made by the Company in or pursuant to Article III of this Agreement (in each case without giving effect to materiality qualifications or Material Adverse Effect qualifications with respect to the calculation of Damages incurred by a Parent Indemnitee); (ii) any breach of any covenant or agreement made by the Company in or pursuant to this Agreement; (iii) any claim by any Person for brokerage or finder’s fees or commissions or similar payments based upon any agreement or understanding alleged to have been made by any such Person with the Company or any Company Stockholder (or any Person acting on their behalf) in connection with any transactions contemplated by this Agreement; (iv) any Long Term Liabilities that are unpaid as of the Closing and not taken into account in the final calculation of Closing Net Debt on the Closing Statement; (v) any expenses incurred by Parent in excess of the initial Expense Fund pursuant to Section 7.2(g)(vii); (vi) any Transfer Taxes allocated to the Company Stockholders pursuant to Section 5.7.(f); or (vii) the matter set forth on Schedule 7.2(a)(viii) of the Parent Disclosure Letter. Notwithstanding anything to the contrary herein, the Company makes no representations or warranties with respect to the ability of Parent or any of its Affiliates to utilize net operating losses of the Company after the Closing.

For purposes of clarifying the meaning of “several” indemnification by each Company Stockholder under this Section 7.2(a), (x) any portion of the Escrow Account that is distributed to Parent pursuant to this Article VII shall be deemed to have been “severally” recovered from all of the Company Stockholders, and (y) with respect to Claims for indemnification under this Section 7.2(a) that are not recovered from the Escrow Account, (i) if any indemnification payment is owed, each Company Stockholder’s indemnification obligation pursuant to this Article VII shall be equal to (and limited to) such Company Stockholder’s Pro Rata Portion of the applicable Damages with respect to which the indemnification payment is made (except in the case of fraud, which shall be interpreted to require the element of scienter) committed by a Company Stockholder and (ii) such Claim shall be subject to Section 7.2.(h).

(b) By Parent. Parent shall indemnify, save and hold harmless the Company Stockholders (collectively, the “Company Stockholder Indemnitees”), from and against any and all Damages incurred in connection with, arising out of, resulting from or incident to (i) any breach of any representation or warranty or the inaccuracy of any representation made by Parent or Merger Sub in or pursuant to Article IV of this Agreement (in each case without giving effect to materiality qualifications or Material Adverse Effect qualifications with respect to the calculation of Damages incurred by a Company Stockholder Indemnitee); or (ii) any breach of any covenant or agreement made by Parent or Merger Sub in or pursuant to this Agreement.

A-61

Table of Contents

(c) Cooperation. The indemnified party and the indemnifying party shall cooperate with each other and their attorneys in the investigation, trial and defense of any lawsuit or action arising from third party claims and any appeal arising therefrom; provided, however, that the party not controlling the defense of such lawsuit or action may, at its own cost, participate in (but not control) the investigation, trial and defense of such lawsuit or action and any appeal arising therefrom. The parties shall cooperate with each other in any notifications to insurers.

(d) Indemnifying Parties. References in this Article VII to “indemnifying party” shall be deemed to be references to the Company Stockholders collectively from and after the Closing (and to the Company Stockholders and the Company prior to the Closing) and, for the avoidance of doubt, the Stockholder Representative shall represent the Company Stockholders with respect to all such matters as provided in Section 7.2.(g) except for any right or obligation to receive or make payment (and any notice requirement with respect to any notice required to be provided under this Article VII by an indemnified party shall be deemed satisfied if such notice is delivered to the Stockholder Representative).

(e) Procedure for Indemnification; Defense of Third-Party Claims.

(i) If an indemnification claim for Damages pursuant to this Article VII (a “Claim”) is to be made by an indemnified party hereunder for any matter not involving a third party claim, such claim shall be asserted by the indemnified party by delivery of a written notice describing the claim with reasonable specificity, a good faith estimate of the amount thereof (if known) and the basis thereof (a “Claim Notice”) to the indemnifying party as soon as reasonably practicable after the indemnified party becomes aware of any fact, condition or event which is reasonably likely to give rise to Damages for which indemnification may be sought under this Article VII, provided, that the failure of the indemnified party to give prompt notice hereunder shall not affect rights to indemnification hereunder, except to the extent that the indemnifying party demonstrates actual damage caused by such failure. Following the delivery of a Claim Notice, the indemnifying party and its Representatives shall be given access (including electronic access, to the extent available) at reasonable times as they may reasonably require to the Books and Records of the Company and Protonex LLC and access to such personnel or representatives of the Company and its Representatives, including but not limited to the individuals responsible for the matters that are subject of the Claim Notice, at reasonable times as they may reasonably require for the purposes of investigating or resolving any disputes or responding to any matters or inquiries raised in the Claim Notice; provided that the indemnified party shall be entitled to withhold information from the indemnifying party if its provision to the indemnifying party would cause the attorney-client privilege thereof to be waived and there is no method of providing such information to the indemnifying party in a manner which would not result in such a waiver.

(ii) If a Claim is to be made by an indemnified party as a result of a third-party claim (a “Third Party Claim”), the indemnified party shall, subject to this Article VII, give a Claim Notice to the indemnifying party with respect to such Claim as soon as practicable after the indemnified party becomes aware of any fact, condition or event which may give rise to Damages for which indemnification may be sought under this Article VII, provided, that the failure of the indemnified party to give prompt notice hereunder shall not affect the rights to indemnification hereunder, except to the extent that the indemnifying party demonstrates actual damage caused by such failure. If any lawsuit or enforcement action is filed by a third party against an indemnified party, written notice thereof shall be given to the indemnifying party as promptly as practicable, provided that the failure of the indemnified party to give prompt notice hereunder shall not affect rights to indemnification hereunder, except to the extent that the indemnifying party demonstrates actual damage caused by such failure. The Stockholder Representative shall be entitled, if it so elects at the cost and expense of the Company Stockholders, to participate in the defense of such claim and Parent shall consider in good faith any reasonable comments or recommendations of the Stockholder Representative with respect to the defense of such claim, it being understood that the Parent shall have the sole right to control such defense (including the right to settle

A-62

Table of Contents

any such claim, subject to Section 7.2(e)(iii), if applicable); provided, further, that the parties shall cooperate in good faith to implement reasonable arrangements designed to preserve any existing attorney-client privilege; provided, further, that the indemnified party shall be entitled to withhold information from the indemnifying party if its provision to the indemnifying party would cause the attorney-client privilege thereof to be waived and there is no method of providing such information to the indemnifying party in a manner which would not result in such a waiver.

(iii) Except for third-party claims (A) seeking non-monetary remedy, (B) seeking claims for equitable relief, or (C) involving potential criminal liability, if the Stockholder Representative provides written notice to Parent within 30 days after receipt of a Claim Notice in respect of a third-party claim for which a Parent Indemnitee is seeking indemnification hereunder, which notice by the Stockholder Representative irrevocably acknowledges the Company Stockholders’ obligation to indemnify such claim fully, a Parent Indemnitee shall not enter into a settlement of such third-party claim without the prior written consent of the Stockholder Representative (such consent not to be unreasonably withheld, conditioned or delayed).

(iv) After the giving of any Claim Notice pursuant hereto, the amount of indemnification to which an indemnified party shall be entitled under this Article VII shall be determined: (a) by the written agreement between Parent and the Stockholder Representative; (b) by a decision of the Arbitrator as contemplated by Section 9.16; or (c) by any other means to which Parent and the Stockholder Representative shall agree. Within thirty days after delivery of a Claim Notice, the indemnifying party shall deliver to the indemnified party a written response. If any dispute with respect to the matters set forth in the Claim Notice is not resolved within thirty days following the delivery by the indemnifying party of such response, Parent and the Stockholder Representative shall each have the right to submit such dispute to dispute resolution in accordance with the provisions of Section 9.16. If it shall be determined upon resolution of a Claim as provided herein that a Parent Indemnitee is entitled to indemnification hereunder, such Parent Indemnitee shall be entitled to recover Damages as provided in Section 7.2(a) hereof. If it shall be determined upon resolution of a Claim as provided herein that a Company Stockholder Indemnitee is entitled to recover any amount from Parent pursuant to this Article VII, Parent shall satisfy its indemnification obligations hereunder by, at Parent’s sole election, either (A) delivering to the Company Stockholder Indemnitees shares of Parent Common Stock having a value equal to such amount (which shares shall be valued at the Price Per Share for this purpose) or (B) paying to the Company Stockholder Indemnitees such amount by check or by wire transfer of immediately available funds.

(f) Provisions Relating to Damages.

(i) The term “Damages” as used in this Article VII is not limited to matters asserted by third parties against a Parent Indemnitee, but includes Damages incurred or sustained by a Parent Indemnitee in the absence of third-party claims. Payments by a party of amounts for which such party is indemnified hereunder shall not be a condition precedent to recovery. No Company Stockholder shall have any right to reimbursement or contribution from, subrogation to or indemnification from the Surviving Corporation (or any Affiliate thereof) with respect to any indemnification claim of a Parent Indemnitee against any Company Stockholder hereunder or otherwise in connection with this Agreement.

(ii) Notwithstanding the foregoing, the term “Damages” as used in this Article VII (A) shall be calculated net of any insurance proceeds actually received by the indemnified party with respect to the applicable Claim (but Damages shall include a reasonable estimate of Damages resulting from increased future premiums (if any) resulting from such Claim) and (B) the fees and expenses of only one firm of attorneys (and, where applicable, separate local counsel in the relevant jurisdictions) representing the indemnified parties shall be included in Damages unless said firm of attorneys determines that a conflict of interest would make joint representation of all indemnified parties inadvisable.

A-63

Table of Contents

(iii) The right to indemnification, payment of Damages or other remedy based on any representations, warranties, covenants and obligations will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or obligation. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, will not affect the right to indemnification, payment of Damages, or other remedies based on such representations, warranties, covenants and obligations.

(iv) Notwithstanding anything to the contrary in this Agreement, in no event shall any party be liable for, and Damages shall not include, any punitive damages (except for punitive damages that are the subject of third party claims) and no “multiple of profits” or “multiple of cash flow” or similar valuation methodologies based on multiples shall be used in calculating the amount of any Damages. For the avoidance of doubt, any recovery of consequential damages by an indemnified party hereunder will be limited to consequential damages that an indemnified party would have the right to recover under applicable general principles of contract law under the circumstances (e.g. reasonably foreseeable damages); provided that nothing in this sentence will limit the ability of an indemnified party to recover any consequential damages that are the subject of a third party claim.

(g) Appointment of the Stockholder Representative.

(i) By executing this Agreement, the Company (and, upon approval of this Agreement, execution of the Written Consent or a Stockholder Transmittal Letter, each Company Stockholder) shall be deemed to have constituted and appointed, effective from and after the date of this Agreement, Edward J. Stewart as the agent and attorney-in-fact for and on behalf of each Company Stockholder to act as the Stockholder Representative under this Agreement in accordance with the terms of this Section 7.2.(g). In the event of the resignation, removal, dissolution, liquidation, bankruptcy, death or incapacity of the Stockholder Representative, the Company Stockholders shall promptly appoint a successor Stockholder Representative (and in any event within ten Business Days of such vacancy), and such appointment shall become effective as to any such successor when a copy of such instrument shall have been delivered to Parent. The Stockholder Representative may resign at any time. The Company Stockholders holding a majority of the Pro Rata Portion of all of the Company Stockholders shall have the right to remove a Stockholder Representative and to appoint a successor Stockholder Representative. The Stockholder Representative shall have full power and authority to represent all of the Company Stockholders and their successors with respect to all matters arising under this Agreement, and all actions taken by the Stockholder Representative hereunder shall be binding upon all such Company Stockholders as if expressly confirmed and ratified in writing by each of them, and no Company Stockholders shall have the right to object, dissent, protest or otherwise contest the same. The Stockholder Representative shall take any and all actions that it believes are necessary or appropriate under this Agreement and the Escrow Agreement for and on behalf of the Company Stockholders as if the Company Stockholders were acting on their own behalf, including giving and receiving any notice or instruction permitted or required under this Agreement or the Escrow Agreement by the Stockholder Representative or any Company Stockholders, interpreting all of the terms and provisions of this Agreement and the Escrow Agreement, authorizing payments to be made with respect hereto, defending all Claims against the Company Stockholders pursuant to Section 7.2(a) of this Agreement, consenting to, compromising or settling all indemnification claims, conducting negotiations with Parent and its agents regarding such claims, dealing with Parent under this Agreement and the Escrow Agreement with respect to all matters arising under this Agreement or the Escrow Agreement, taking any and all other actions specified in or contemplated by this Agreement and the Escrow Agreement and engaging counsel, accountants or other agents in connection with the foregoing matters.

Representative’s execution and performance of this Agreement and the Escrow Agreement, in each case as such Representative Loss is suffered or incurred; provided, that in the event that any such Representative Loss is finally adjudicated to have been directly caused by the gross negligence or willful misconduct of the Stockholder Representative, the Stockholder Representative will reimburse the Company Stockholders the amount of such indemnified Representative Loss to the extent attributable to such gross negligence or willful misconduct. If not paid directly to the Stockholder Representative by the Company Stockholders, any such Representative Losses may be recovered by the Stockholder Representative from the amounts in the Escrow Account at such time as remaining amounts would otherwise be distributable to the Company Stockholders; provided, that while this section allows the Stockholder Representative to be paid from the Escrow Account, this does not relieve the Company Stockholders from their obligation to promptly pay such Representative Losses as they are suffered or incurred, nor does it prevent the Stockholder Representative from seeking any remedies available to it at law or otherwise. In no event will the Stockholder Representative be required to advance its own funds on behalf of the Company Stockholders or otherwise. The Company Stockholders acknowledge and agree that the foregoing indemnities will survive the resignation or removal of the Stockholder Representative or the termination of this Agreement. None of Parent, the Company or Merger Sub shall have any obligation to reimburse the Stockholder Representative for any such expenses.

(iv) Without limiting the generality of this Section 7.2.(g), following the Effective Time, the Company Stockholders agree that the Stockholder Representative shall act as representative of the Company Stockholders for all purposes under this Article VII. Parent agrees that any claim for indemnification made by any of the Parent Indemnitees pursuant to this Agreement shall be made exclusively through the Stockholder Representative acting on behalf of the Company Stockholders (and the Company Stockholders agree that any such claim against the Company Stockholders by a Parent Indemnitee may be made by providing notice of such claim to the Stockholder Representative).

(v) The Stockholder Representative is hereby appointed and constituted the true and lawful attorney-in-fact of each Company Stockholder, with full power in his, her or its name and on his, her or its behalf to act according to the terms of this Agreement and the Escrow Agreement in the absolute discretion of the Stockholder Representative and in general to do all things and to perform all acts. This power of attorney and all authority hereby conferred is granted and shall be irrevocable and shall not be terminated by any act of any Company Stockholder, by operation of law (whether by such Company Stockholder’s death, disability protective supervision) or any other event. Without limitation to the foregoing, this power of attorney is to ensure the performance of a special obligation, and, accordingly, each Company Stockholder hereby renounces its, his or her right to renounce this power of attorney unilaterally. Each Company Stockholder hereby waives any and all defenses that may be available to contest, negate or disaffirm the action of the Stockholder Representative taken in good faith under this Agreement or the Escrow Agreement. Notwithstanding the power of attorney granted in this Section 7.2.(g), no agreement, instrument, acknowledgement or other act or document shall be ineffective by reason only of the Company Stockholders having signed or given such directly instead of the Stockholder Representative.

(vi) Any action taken by the Stockholder Representative pursuant to the authority granted in this Section 7.2.(g) shall be effective and absolutely binding on each Company Stockholder notwithstanding any contrary action of, or direction from, any Company Stockholder.

(vii) Immediately prior to Closing, Parent will wire to the Stockholder Representative US$25,000 (the “Expense Fund”), which will be used for the purposes of paying directly, or reimbursing the Stockholder Representative for, any third party expenses pursuant to this Agreement and the Escrow Agreement. In the event Stockholder Representative’s expenses exceed, or are reasonably expected to exceed, the amount of the Expense Fund, Parent will wire Stockholder Representative additional funds to be used for purposes of paying such expenses; provided that, Parent shall recover from the Escrow

Account the amount of such additional expenses in the manner set forth in Section 7.3. The Stockholder Representative will not be liable for any loss of principal of the Expense Fund other than as a result of its gross negligence or willful misconduct. The Stockholder Representative will hold these funds separate from his personal funds, will not use these funds for his personal expenses or any other purposes and will not voluntarily make these funds available to his creditors in the event of bankruptcy. Contemporaneous with or as soon as practicable following the completion of the Stockholder Representative’s responsibilities hereunder, the Stockholder Representative shall disburse the balance of the Expense Fund to the Parent.

(h) Limitations on Indemnity.

(i) The Company Stockholders shall not be liable under this Article VII for any Damages until the aggregate amount otherwise due to the Parent Indemnitees or Company Stockholder Indemnitees, as the case may be, exceeds an accumulated total of $250,000 (the “Basket”); provided, however, that this limitation shall apply only to the extent the Parent Indemnitees are entitled to indemnification exclusively under Section 7.2 (a)(i) (in the case of a claim for Damages by the Parent Indemnitees) or Section 7.2 (b)(i) (in the case of a claim for Damages by the Stockholder Representative on behalf of the Company Stockholder Indemnitees) and shall not apply in the case of fraud (which shall be interpreted to require the element of scienter). Once the aggregate amount of Damages exceeds the Basket, then the Parent Indemnitees or the Company Stockholder Indemnitees, as the case may be, shall have the right to recover all Damages from and including the first dollar of damages without regard to the Basket, subject to the other limitations set forth in this Article VII.

(ii) The parties agree and acknowledge that in no event shall the aggregate liability of the Company Stockholders in connection with indemnification claims pursuant to Section 7.2(a)(i) exceed an amount equal to the number of Escrowed Shares multiplied by the Price Per Share (including any amounts recovered from the Escrow Account) except in the case of fraud (which shall be interpreted to require the element of scienter).

(iii) The parties agree and acknowledge that, notwithstanding anything contained in this Agreement to the contrary, (A) subject to Section 7.2.(h)(iii)(B), the aggregate liability of the Company Stockholders in connection with indemnification claims pursuant to Section 7.2(a) shall not exceed ten percent of the total value of the Aggregate Consideration (valued at the Price Per Share) payable to the Supporting Stockholders hereunder, except in the case of fraud (which shall be interpreted to require the element of scienter) committed by a Company Stockholder (and in the event of such fraud only with respect to the Company Stockholder who committed such fraud) and (B) Parent shall not be liable to the Company Stockholder Indemnitees pursuant to this Article VII for any Damages in excess, in the aggregate, of the total value of the Aggregate Consideration (valued at the Price Per Share) payable to the Supporting Stockholders hereunder.

(iv) the Parent Indemnitees and the Company Stockholder Indemnitees shall not be entitled to indemnification pursuant to Section 7.2(a) for any Damages underlying any such indemnification claim to the extent that such Damage was specifically taken into account in the determination of the Aggregate Consideration (including any adjustment thereto contemplated by Section 1.12) (it being understood that nothing in this Section 7.2.(h)(iv) shall limit the right of any indemnified party to recover any such Damages to the extent such Damages exceed the amount specifically taken into account in the calculation of the Aggregate Consideration).

7.3. Escrow Account.

(a) In the event of any claim for indemnification under Section 7.2(a) the Parent Indemnitees shall first recover any Damages from the Escrow Account. If the then remaining Escrowed Shares in the

A-67

Table of Contents

Escrow Account are insufficient to cover Damages arising from such Claim, then, on the terms and subject to the conditions set forth herein, the Parent Indemnitees may seek recovery for the remaining amount of such Damages directly from each Company Stockholder in an amount not to exceed such Company Stockholder’s Pro Rata Portion of such remaining amount of Damages; provided, however, that the Company Stockholders may elect to satisfy their indemnification obligations hereunder by (in lieu of cash payment), delivering to Parent shares of Parent Common Stock in book-entry form equal to such amount (which shares shall be valued at the Price Per Share, rounded to the nearest whole share of Parent Common Stock).

(b) Within five (5) Business Days after the resolution pursuant to Section 7.2.(e)(iii) hereof of a Claim for which a Parent Indemnitee is entitled to recover Damages from the Escrow Account, Parent and the Stockholder Representative shall jointly instruct the Escrow Agent to deliver from the Escrow Account to Parent a number of shares of Parent Common Stock in book-entry form equal to the amount of Damages divided by the Price Per Share (which shares shall be valued at the Price Per Share, rounded to the nearest whole share of Parent Common Stock) (or if there are insufficient shares in the Escrow Account to cover such Damages, all shares of Parent Common Stock in the Escrow Account).

(c) Within five (5) Business Days after the one year anniversary of the Closing Date, Parent and the Stockholder Representative shall jointly instruct the Escrow Agent to deliver from the Escrow Account to each Company Stockholder such Company Stockholder’s Pro Rata Allocation of (i) the number of shares of Parent Common Stock remaining in the Escrow Account minus (ii) (A) the Pending Claims Amount determined as of the one year anniversary of the Closing divided by (B) the Price Per Share.

7.4. Exclusive Remedy. Except in the case of fraud or as otherwise provided by applicable law (but without limiting any limitations on remedies as a result of fraud that are expressly set forth in this Article VII), this Article VII shall be the exclusive remedy of the Parent Indemnitees and the Company Stockholder Indemnitees from and after the Closing Date for any and all claims arising under this Agreement, including, without limitation, claims of inaccuracy in or breach of any representation, warranty, covenant, agreement or obligation in this Agreement; provided, however, that the foregoing shall not be deemed a waiver by any party of any right to specific performance or injunctive relief.

Table of Contents

SECTION 262 OF THE GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title and, subject to paragraph (b)(3) of this section, § 251(h) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that, except as expressly provided in § 363(b) of this title, no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either: (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (b)(1) of this section, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a. and b. of this section; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing paragraphs (b)(2)a., b. and c. of this section.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 251(h), § 253 or § 267 of this title is not owned by the parent immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(4) In the event of an amendment to a corporation’s certificate of incorporation contemplated by § 363(a) of this title, appraisal rights shall be available as contemplated by § 363(b) of this title, and the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as practicable, with the word “amendment” substituted for the words “merger or

C-2

Table of Contents

consolidation,” and the word “corporation” substituted for the words “constituent corporation” and/or “surviving or resulting corporation.”

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice or, in the case of a merger approved pursuant to § 251(h) of this title, within the later of the consummation of the tender or exchange offer contemplated by § 251(h) of this title and 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice or, in the case of a merger approved pursuant to § 251(h) of this title, later than the later of the consummation of the tender or exchange offer contemplated by § 251(h) of this title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s

C-3

Table of Contents

shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as

C-4

Table of Contents

established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Under the Canada Business Corporations Act (the “CBCA”), Ballard may indemnify a present or former director or officer of Ballard or another individual who acts or acted at Ballard’s request as a director or officer or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by such individual in respect of any civil, criminal, administrative, investigative or other action, suit or proceeding (a “Proceeding”) in which such individual is involved by reason of such individual’s association with Ballard or other entity and provided that such individual acted honestly and in good faith with a view to the best interests of Ballard or, as the case may be, to the best interests of the other entity for which the individual acted as director or officer or in a similar capacity at Ballard’s request and, in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, had reasonable grounds for believing that such individual’s conduct was lawful. The indemnification may be made in connection with a derivative action only with court approval. Any of the individuals described in the first sentence of this paragraph is entitled to indemnification from Ballard as a matter of right if the individual seeking indemnity (a) was not judged by the court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done and (b) fulfilled the conditions set forth above.

Ballard may advance monies to an individual described above for the costs, charges and expenses of a Proceeding. However, the individual must repay the monies if the individual does not fulfill the conditions set forth above.

The foregoing description is qualified in its entirety by reference to the CBCA.

Ballard is a party to an indemnity agreement with each director and officer of Ballard providing that if such director or officer is or was involved in any threatened, pending or completed Proceeding by reason of the fact that such director or officer is or was a director or officer of Ballard or is or was serving at the request of Ballard as a director or officer of another entity, including service with respect to employee benefit plans, whether the basis of such Proceeding is an alleged action in an official capacity while serving as a director or officer, such director or officer will be indemnified and held harmless by Ballard to the fullest extent authorized by and in the manner set forth in the CBCA against all expense, liability and loss reasonably incurred or suffered by such director or officer in connection therewith. Under such indemnity agreements, Ballard may indemnify any of its directors or officers in connection with a Proceeding (or part thereof) initiated by such director or officer only if such Proceeding (or part thereof) is authorized by the board of directors of Ballard or if such Proceeding is a successful Proceeding, in whole or in part, by a director or officer for claims under an indemnity agreement.

The CBCA provides that Ballard may purchase and maintain insurance for the benefit of any of the individuals described in the first sentence of the first paragraph of this section against any liability incurred by such individual in such individual’s capacity as a director or officer of Ballard or as a director or officer, or similar capacity, of another entity, if the individual acts or acted in that capacity at Ballard’s request.

Ballard maintains directors’ and officers’ liability insurance. The policies insure (a) the directors and officers of Ballard against losses arising from claims against them for certain of their actual or alleged wrongful acts (as defined within the insurance policy), (b) Ballard for payments made pursuant to Ballard’s indemnification of its directors and officers and (c) Ballard when it is directly named in a securities claim. The policies provide a maximum coverage in any one policy year of U.S. $15 million in annual claims (subject to deductibles of U.S. $200,000 to U.S. $500,000 per claim, payable by Ballard). The premiums for the policies were not allocated between directors and officers as separate groups.

By-law No. 1 of Ballard provides that, except as otherwise provided in the CBCA, no director or officer will be liable for:

· the acts, receipts, neglects or defaults of any other person, or for joining in a receipt or act for conformity;

II-1

Table of Contents

· a loss, damage or expense happening to Ballard through the insufficiency or deficiency of title to property acquired by, for, or on behalf of Ballard;

· the insufficiency or deficiency of a security in or upon which moneys of Ballard are invested;

· a loss or damage arising from the bankruptcy, insolvency or wrongful act of a person with whom money, security or other property of Ballard is lodged or deposited; or

· any other loss, damage, or misfortune that may arise out of the execution of the duties of a director or in relation thereto.

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

Item 22. Undertakings

Regulation S-K, Item 512(a) Undertaking: The undersigned registrant hereby undertakes as follows:

(1) |  | to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
|  | (i) |  | to include any prospectus required by Section 10(a)(3) of the U.S. Securities Act of 1933;
|  | (ii) |  | to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement;

II-2

Table of Contents

|  |  |  | and
|  | (iii) |  | to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
(2) |  | that, for the purpose of determining any liability under the U.S. Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;
(3) |  | to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;
(4) |  | to file a post-effective amendment to the registration statement to include any financial statements required by Item 8.A. of Form 20-F at the start of any delayed offering or throughout a continuous offering;
(5) |  | that, for the purpose of determining liability under the U.S. Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use; and
(6) |  | that, for the purpose of determining liability of the registrant under the U.S. Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
|  | (i) |  | any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
|  | (ii) |  | any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
|  | (iii) |  | the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
|  | (iv) |  | any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

Regulation S-K, Item 512(g) Undertaking:

(1) |  | The undersigned registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the undersigned registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.
(2) |  | The registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the U.S. Securities Act of 1933

II-3

Table of Contents

|  | and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the U.S. Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Regulation S-K, Item 512(h) Undertaking:

Insofar as indemnification for liabilities arising under the U.S. Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the U.S. Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the U.S. Securities Act of 1933 and will be governed by the final adjudication of such issue.

Form F-4, Item 22(b) Undertaking:

The undersigned registrant hereby undertakes to (i) respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of Form F-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means, and (ii) to arrange or provide for a facility in the United States for the purpose of responding to such requests. The undertaking in subparagraph (i) above includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

Form F-4, Item 22(c) Undertaking:

The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
