to the Plan, and (iii) make any other determinations that the Board deems necessary or desirable for the administration of the Plan.

The election must be completed, signed and delivered to the Corporation:

subject to (iii), for the Remuneration Period from the Effective Date of the Plan until the next annual meeting of shareholders of the Corporation, within 30 days of the Effective Date of the Plan, in which case the election will only apply to the portion of the Annual Retainer payable with respect to services rendered no earlier than 30 days after the delivery of the election,

(ii)

subject to (iii), for any other Remuneration Period, by April 15 of each year, in which case the election will apply to all amounts of the Annual Retainer payable with respect to services rendered during the entire Remuneration Period, and

(iii)

for an Eligible Person who is not a U.S. Director and who was not an Eligible Person either on the Effective Date of the Plan or on April 15 of a particular year, within 30 days of becoming an Eligible Person, in which case the election will only apply to the portion of the Annual Retainer payable with respect to services rendered no earlier than 30 days after the delivery of the election.

If no election is made in respect of a particular calendar year, the new or existing Eligible Person who is not a U.S. Director will receive the Eligible Remuneration in Shares.

Each Eligible Person who is a U.S. Director may elect, with respect to a Remuneration Period, to be paid a percentage (from zero to one hundred percent) of his or her Eligible Remuneration that represents the Annual Retainer, net of any Applicable Withholding Taxes, in Deferred Share Units, with the balance, if any, being paid in Shares. The election must be completed, signed and delivered to the Corporation

(i)

subject to (ii), for any Remuneration Period, by December 31 of each year, in which case the election will apply to all amounts of the Annual Retainer payable with respect to services rendered during the following calendar year, notwithstanding the fact that services rendered during the latter portion of the calendar year are rendered in a subsequent fiscal year. When a an Eligible Person who is a U.S. Director makes an election relating to shares or deferred share units for a period of performance for which the Corporation has not yet determined the total number of shares and/or deferred share units that will be payable as compensation to that Eligible Person for the period in question, the Eligible Person’s election must specify the percentage of compensation that the Eligible Person elects to receive in shares and the percentage of compensation that the Eligible Person elects to receive in deferred share units, and the Corporation will apply the percentages set out in the election to the compensation at the time that the Corporation determines the number of shares or deferred share units that will be payable during the performance period for which the election is made, and

(ii)

for an Eligible Person who is a U.S. Director and who was not an Eligible Person either on the Effective Date of the Plan or on December 31 of a particular year and who has not previously participated in this Plan or any other plan that is required to be aggregated with this Plan for purposes of Section 409A of the Code, within 30 days of becoming an Eligible Person, in which case the election will only apply to the portion of the Annual Retainer payable with respect to services rendered no earlier than 30 days after the delivery of the election. If no election is made in respect of a particular calendar year, the new or existing Eligible Person will receive the Eligible Remuneration in Shares.

The Board may, to the extent permitted by law, delegate any of its responsibilities under the Plan and powers related thereto to the Committee or to one or more officers of the Corporation and all actions taken and decisions made by the Committee or by such officers in this regard shall be final, conclusive and binding on all parties concerned, including, but not limited to, the Corporation, the Eligible Person, and, if applicable, the estate or legal representative of the Eligible Person.

Subject to terms of the Plan and any rules, approvals and conditions as the Board may impose, an Eligible Person may elect to receive his or her Eligible Remuneration in the form of Deferred Share Units. Deferred Share Units pursuant to the Plan will be credited to an account maintained for each Eligible Person by the Corporation twice a year in March and September or as otherwise determined by the Corporation. The number of Deferred Share Units (including fractional Deferred Share Units, computed to three digits) to be credited to an Eligible Person will be determined on the date approved by the Board by dividing the amount of the Eligible Remuneration to be deferred into Deferred Share Units by the Fair Market Value per Share on that date.

In the event the Board approves the issue of Deferred Share Units as contemplated by Section 2.1 of this Plan at a meeting of the Board that occurs during a trading blackout imposed by the Corporation pursuant to the terms of the Corporation's trading policy (the "Blackout"), the number of Deferred Share Units (including fractional Deferred Share Units, computed to three digits) to be credited to an Eligible Person will be determined on the date that the Blackout is lifted by dividing the amount of the Eligible Remuneration to be deferred into Deferred Share Units by the Fair Market Value per Share on the date that the Blackout is lifted.

On any date on which a dividend is paid on Shares, an Eligible Person’s account will be credited with the number of Deferred Share Units (including fractional Deferred Share Units, computed to three digits) calculated by (i)

multiplying the amount of the dividend per Share by the aggregate number of Deferred Share Units that were credited to the Eligible Person’s account as of the record date for payment of the dividend, and (ii) dividing the amount obtained in (i) by the Fair Market Value on the date on which the dividend is paid.

A written confirmation of the balance in each Eligible Person’s account will be sent by the Corporation to the Eligible Person upon request of the Eligible Person.

In the event of any stock dividend, stock split, combination or exchange of shares, merger, consolidation, spin-off or other distribution of Corporation assets to shareholders, or any other change in the capital of the Corporation affecting Shares, the Board, in its sole and absolute discretion, will make, with respect to the number of Deferred Share Units outstanding under the Plan, any proportionate adjustments as it considers appropriate to reflect that change.

2.6.1.1

An Eligible Person who is not a U.S. Director and who has Terminated Service may receive Shares in respect of the Deferred Share Units credited to the Eligible Person’s account (determined in accordance with section 2.6.1.2) by filing with the Secretary of the Corporation a notice of redemption in the form prescribed from time to time by the Corporation on or before December 15 of the first calendar year commencing after the date of the Eligible Person’s Terminated Service. If the Eligible Person fails to file such notice on or before that December 15, the Eligible Person will be deemed to have filed with the Secretary of the Corporation a notice of redemption on that December 15. The date on which a notice is filed or deemed to be filed with the Secretary of the Corporation is the “Filing Date”. The Corporation shall have the discretion to defer the Filing Date to any other date if such deferral is, in the sole opinion of the Corporation, desirable to ensure compliance with section 3.3.

2.6.1.2

The notice filed by the Eligible Person who is not a U.S. Director will specify that the Eligible Person desires to receive a Share for each Deferred Share Unit (net of any Applicable Withholding Tax). The Corporation shall issue one Share for each whole Deferred Share Unit to the Eligible Person. Such payment shall be made by the Corporation as soon as reasonably possible following the Filing Date. In no event will payment be made later than December 31 of the first calendar year commencing after the Eligible Person has Terminated Service. Fractional Shares shall not be issued, and where an Eligible Person would be entitled to receive a fractional Share in respect of any fractional Deferred Share Unit, the Corporation shall pay to such Eligible Person, in lieu of such fractional Share, cash equal to the Fair Market Value of such fractional Share, calculated as at the day before such payment is made.

2.6.1.3

In the event of the death of an Eligible Person who is not a U.S. Director, the Corporation will, within two months of the Eligible Person’s death, issue one Share for each whole Deferred Share Unit credited to the deceased Eligible Person’s account (net of any Applicable Withholding Tax) to or for the benefit of the legal representative of the Eligible Person. Fractional Shares shall not be issued, and where the legal representative would be entitled to receive a fractional Share in respect of any fractional Deferred Share Unit, the Corporation shall pay to such legal representative, in lieu of such fractional Share, cash equal to the Fair Market Value of such fractional Share, calculated as at the day before such payment is made.

2.6.1.4

If an Eligible Person who is not a U.S. Director dies after the Eligible Person has Terminated Service but before filing a notice of redemption with the Corporate Secretary of the Corporation, section 2.6.1.3 will apply provided that, in no event will payment be made later than December 31 of the first calendar year commencing after the Eligible Person has Terminated Service.

2.6.2.1

In the event that an Eligible Person who is a U.S. Director has Terminated Service, the Corporation will issue one Share for each whole Deferred Share Unit credited to the Eligible Person’s account (net of any Applicable Withholding Tax) to

the Eligible Person. Except as otherwise provided herein and subject to section 3.3, such payment shall be made by the Corporation as soon as reasonably possible (but in all events within ninety days) following the first date on which the Eligible Person has Terminated Service. Notwithstanding the foregoing, if an Eligible Person who is a U.S. Director is, at the commencement of Terminated Service, a Specified Employee, then the payment (delivery of Shares) will be delayed at least six (6) months following such commencement of Terminated Service and will occur on the first business day following the expiration of that six (6) month period. For this purpose, Specified Employee means an individual who is a specified employee for purposes of Section 1.409A-1(i) of the Treasury Regulations, as determined in accordance with such regulations under the rules and procedures set forth in the separate document entitled "Ballard Power Systems Inc. Specified Employee Determination". Fractional Shares shall not be issued, and where the Eligible Person would be entitled to receive a fractional Share in respect of any fractional Deferred Share Unit, the Corporation shall pay to such Eligible Person (on the same date on which Shares are delivered, as described above), in lieu of such fractional Share, cash equal to the Fair Market Value of such fractional Share, calculated as at the day before such payment is made.

2.6.2.2

In the event of the death of an Eligible Person who is a U.S. Director, the Corporation will issue one Share for each whole Deferred Share Unit credited to the deceased Eligible Person’s account (net of any Applicable Withholding Tax) to or for the benefit of the legal representative of the Eligible Person. Subject to section 3.3, such payment shall be made by the Corporation as soon as reasonably possible (but in all cases within ninety days) following the date of death of the Eligible Person. Fractional Shares shall not be issued, and where the legal representative would be entitled to receive a fractional Share in respect of any fractional Deferred Share Unit, the Corporation shall pay to such legal representative, in lieu of such fractional Share, cash equal to the Fair Market Value of such fractional Share, calculated as at the day before such payment is made.

The Corporation shall be authorized to deduct such taxes and other amounts as it may be required by law to withhold, in such manner as it determines (“Applicable Withholding Tax”). The Corporation may require Eligible Persons to deliver undertakings to, or indemnities in favour of, the Corporation respecting the payment by such Eligible Persons of applicable income or other taxes.

No Director shall have any right or entitlement to be selected or designated as an Eligible Person by the Board. The selection or designation of any Director shall be in the sole and absolute discretion of the Board and any decision of the Board shall be final, binding and conclusive on all parties concerned.

An Eligible Person may not assign any Deferred Share Unit or any other right, benefit or interest in this Plan without the written consent of the Corporation, and any purported assignment without such consent will be void and need not be recognized by the Corporation, except that in the event of the death of the Eligible Person, the legal representatives of the Eligible Person will be entitled to receive the amount of any payment otherwise payable to the Eligible Person hereunder in accordance with the provisions hereof.

Neither participation in the Plan nor any action under the Plan will be construed to give any Eligible Person a right to be retained in the service of the Corporation.

The Board and each Eligible Person will ensure that all actions taken and decisions made by the Board or an Eligible Person, as the case may be, pursuant to the Plan comply with any applicable securities regulation and stock exchange requirements, and policies of the Corporation relating to insider trading or “blackout” periods.

This Plan will enure to the benefit of and be binding upon the respective legal representatives of the Eligible Person.

Without limiting the generality of the foregoing and notwithstanding any other section of this Plan, unless specifically required by any stock exchange or regulatory authority, the Board may make any of the following amendments to the Plan and/or any Deferred Share Unit previously granted without obtaining shareholder approval:

3.5.2

amendments to any provisions relating to the granting or redemption of Deferred Share Units, including but not limited to provisions relating to the term, termination, and the number of Deferred Share Units to be awarded, provided that, without shareholder approval, such amendment does not entail:

3.5.2.1

a reduction to the Fair Market Value used to calculate the number of Deferred Share Units to be awarded to an Eligible Person;

under this Plan or any other incentive or compensation plan involving the issuance or potential issuance of Shares, which could exceed 10% of the Corporation's issued and outstanding Shares;

3.5.2.4

permitting Deferred Share Units to be transferable or assignable other than for normal course estate settlement purposes; or

3.5.3

any amendment in respect of the persons eligible to participate in the Plan, provided that, without shareholder approval, such amendment does not permit non-employee directors to re-gain participation rights under the Plan at the discretion of the Board if their eligibility to participate had previously been removed or increase limits previously imposed on non-employee director participation;

3.5.4

such amendments as are necessary for the purpose of complying with any changes in any relevant law, rule, regulation, regulatory requirement or requirement of any applicable stock exchange or regulatory authority; or

The Board may terminate the Plan at any time, but no termination will, without the consent of the Eligible Person or unless required by law, adversely affect the rights of an Eligible Person with respect to Deferred Share Units to which the Eligible Person is then entitled under the Plan.

The Plan and all matters to which reference is made in the Plan will be governed by and construed in accordance with the laws of the Province of British Columbia, and the laws of Canada applicable therein.

The existence of any Deferred Share Units shall not affect in any way the right or power of the Corporation or its shareholders to make or authorize any adjustment, recapitalization, reorganization or other change in the Corporation's capital structure or its business, or to create or issue any bonds, debentures, shares or other securities of the Corporation or to amend or modify the rights and conditions attaching thereto or to effect the dissolution or liquidation of the Corporation, or any amalgamation, combination, merger or consolidation involving the Corporation or any sale or transfer of all or any part of its assets or business, or any other corporate act or proceeding, whether of a similar nature or otherwise.

Under no circumstances shall Deferred Share Units be considered Shares or other securities of the Corporation, nor shall they entitle any Eligible Person to exercise voting rights or any other rights attaching to the ownership of Shares or other securities of the Corporation, nor shall any Eligible Person be considered the owner of the Shares by virtue of the award of Deferred Share Units.

No amount will be paid to, or in respect of, an Eligible Person under the Plan to compensate for a downward fluctuation in the price of a Share, nor will any other form of benefit be conferred upon, or in respect of, an Eligible Person for such purpose.

The Corporation intends that the Plan comply with the requirements of section 409A of the Code insofar as the Plan pays benefits that (i) are subject to taxation under the Code, and (ii) are subject to section 409A of the Code, and will administer the Plan accordingly. Neither the Corporation nor any of its officers, directors, agents or affiliates shall be obligated, directly or indirectly, to any U.S. Director or any other person for any taxes, penalties, interest or like amounts that may be imposed on the U.S. Director or other person on account of any amounts under the Plan or on account of any failure to comply with any Code section.
