Except as expressly set forth in this Section 1(a), all outstanding options, stock appreciation rights and stock awards granted under the Prior Plan shall remain subject to the terms of the Prior Plan. Any shares of Common Stock subject to outstanding options and stock appreciation rights granted under the Prior Plan (together, the “Prior Plan Appreciation Awards”) and stock awards granted under the Prior Plan that (i) expire or terminate for any reason prior to exercise or settlement, (ii) are forfeited, cancelled or otherwise returned because of the failure to meet a contingency or condition required to vest such shares, or (iii) other than with respect to a Prior Plan Appreciation Award, are reacquired or withheld (or not issued) to satisfy a tax withholding obligation (collectively, the “Prior Plan’s Returning Shares”) shall become available for issuance pursuant to Stock Awards granted hereunder in accordance with the provisions of Section 4(c) below. All Stock Awards granted subsequent to the Effective Date of this Plan shall be subject to the terms of this Plan.

(b) Eligible Stock Award Recipients. The persons eligible to receive Stock Awards are Employees, Directors and Consultants.

(c) Available Stock Awards. The purpose of the Plan is to provide a means by which eligible recipients of Stock Awards may be given an opportunity to benefit from increases in value of the Common Stock through the granting of the following Stock Awards: (i) Options, (ii) Restricted Stock Awards, (iii) Stock Appreciation Rights, (iv) Restricted Stock Units, and (v) Other Stock Awards.

(d) General Purpose. The Company, by means of the Plan, seeks to retain the services of the group of persons eligible to receive Stock Awards, to secure and retain the services of new members of this group and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Affiliates.

(a)    “Affiliate” means any “parent corporation” or “subsidiary corporation” of the Company, whether now or hereafter existing, as those terms are defined in Sections 424(e) and (f), respectively, of the Code. The Board shall

have the authority to determine the time or times at which “parent corporation” or “subsidiary corporation” status is determined within the foregoing definition.

(b)    “Board” means the Board of Directors of the Company.

(c)    “Capitalization Adjustment” has the meaning ascribed to that term in Section 11(a).

(i) any Exchange Act Person becomes the Owner, directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the combined voting power of the Company’s then outstanding securities other than by virtue of a merger, consolidation or similar transaction. Notwithstanding the foregoing, a Change in Control shall not be deemed to occur (A) on account of the acquisition of securities of the Company by an institutional investor, any affiliate thereof or any other Exchange Act Person that acquires the Company’s securities in a transaction or series of related transactions that are primarily a private financing transaction for the Company or (B) solely because the level of Ownership held by any Exchange Act Person (the “Subject Person”) exceeds the designated percentage threshold of the outstanding voting securities as a result of a repurchase or other acquisition of voting securities by the Company reducing the number of shares outstanding, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of voting securities by the Company, and after such share acquisition, the Subject Person becomes the Owner of any additional voting securities that, assuming the repurchase or other acquisition had not occurred, increases the percentage of the then outstanding voting securities Owned by the Subject Person over the designated percentage threshold, then a Change in Control shall be deemed to occur;

(ii) there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company if, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing more than fifty percent (50%) of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) more than fifty percent (50%) of the combined outstanding voting power of the parent of the surviving Entity in such merger, consolidation or similar transaction;

(iii) there is consummated a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries, other than a sale, lease, license or other disposition of all or substantially all of the consolidated assets of the Company and its Subsidiaries to an Entity, more than fifty percent (50%) of the combined voting power of the voting securities of which are Owned by stockholders of the Company in substantially the same proportion as their Ownership of the Company immediately prior to such sale, lease, license or other disposition; or

The term Change in Control shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company.

Notwithstanding the foregoing or any other provision of this Plan, the definition of Change in Control (or any analogous term) in an individual written agreement between the Company or any Affiliate and the Participant shall supersede the foregoing definition with respect to Stock Awards subject to such agreement (it being understood, however, that if no definition of Change in Control or any analogous term is set forth in such an individual written agreement, the foregoing definition shall apply); provided, however, that no Change in Control will be deemed to occur upon announcement or commencement of a tender offer or upon a potential takeover or upon stockholder approval of a merger or other transaction, in each case without a requirement that the Change in Control actually occur.

A change in the capacity in which the Participant renders service to the Company or an Affiliate as an Employee, Consultant or Director or a change in the entity for which the Participant renders such service, provided that there is no interruption or termination of the Participant’s service with the Company or an Affiliate, shall not terminate a Participant’s Continuous Service; provided, however, if the Entity for which a Participant is rendering services ceases to qualify as an Affiliate, as determined by the Board in its sole discretion, such Participant’s Continuous Service shall be considered to have terminated on the date such Entity ceases to qualify as an Affiliate. For example, a change in status from an employee of the Company to a consultant to an Affiliate or to a Director shall not constitute an interruption of Continuous Service. To the extent permitted by law, the Board or the chief executive officer of the Company, in that party’s sole discretion, may determine whether Continuous Service shall be considered interrupted in the case of any leave of absence approved by that party, including sick leave, military leave or any other personal leave. Notwithstanding the foregoing, a leave of absence shall be treated as Continuous Service for purposes of vesting in a Stock Award only to such extent as may be provided in the Company’s leave of absence policy or in the written terms of the Participant’s leave of absence.

The Board may delegate administration of the Plan to a Committee or Committees of one or more members of the Board, and the term “Committee” shall apply to any person or persons to whom such authority has been delegated. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan to the Board shall thereafter be to the Committee or subcommittee), subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan.

(ii)     Rule 16b-3 Compliance. In the discretion of the Board, the Committee may consist solely of two or more Non-Employee Directors, in accordance with Rule 16b-3.

(a)    Share Reserve. Subject to the provisions of Section 11(a) relating to Capitalization Adjustments, the aggregate number of shares of Common Stock that may be issued pursuant to Stock Awards granted on or after January 1, 2021 shall not exceed 22,223,817 (the “2007 Plan Reserve”). For clarity, the 2007 Plan Reserve in this Section 4(a) is a limitation on the number of shares of Common Stock that may be issued pursuant to Stock Awards granted under the Plan after January 1, 2021. Accordingly, this Section 4(a) does not limit the granting of Stock Awards except as provided in Section 8(a). Shares may be issued in connection with a merger or acquisition as permitted by NASDAQ Listing Rule 5635(c) or, if applicable, NYSE Listed Company Manual Section 303A.08, AMEX Company Guide Section 711, Toronto Stock Exchange Company Manual Section 613 or other applicable rule, and such issuance shall not reduce the number of shares available for issuance under the Plan.

(b)    Subject to Section 4(c), from and after January 1, 2021 the 2007 Plan Reserve shall be reduced by one share for each share of Common Stock issued pursuant to a Stock Award.

(c)    Reversion of Shares to the Share Reserve.

(i)    Shares Available for Subsequent Issuance. If any shares of Common Stock issued pursuant to a Stock Award (including, for the avoidance of doubt, Stock Awards granted under the Plan prior to January 1, 2021) are (A) not issued or forfeited back to the Company because of the failure to meet a contingency or condition required to vest such shares covered by such Stock Award having been issued or (B) not issued or reacquired by the Company pursuant to Section 10(f) in connection with a Full Value Award, such shares shall again become available for issuance under the Plan (the “2007 Plan Returning Shares”).

(ii)    Shares Not Available for Subsequent Issuance. If any shares subject to a Stock Award or a Prior Plan Appreciation Award are not delivered to a Participant because the Stock Award is exercised through a

reduction of shares subject to the Stock Award or Prior Plan Appreciation Award (i.e., “net exercised”), the number of shares that are not delivered to the Participant shall no longer be available for issuance under the Plan. Also, any shares reacquired by the Company pursuant to Section 10(f) upon the exercise of an Option or Stock Appreciation Right or a Prior Plan Appreciation Award, any shares used as consideration for the exercise of an Option or Stock Appreciation Right or a Prior Plan Appreciation Award or any shares repurchased by the Company on the open market with the proceeds of an Option or Stock Appreciation Right exercise price or a Prior Plan Appreciation Award exercise price shall no longer be available for issuance under the Plan.

(d)    Source of Shares. The shares of Common Stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise.

(a)    Eligibility for Specific Stock Awards. Stock Awards may be granted to Employees, Directors and Consultants.

(b)     Limitation on Annual Grants. Subject to the provisions of Section 11(a) relating to Capitalization Adjustments, no Employee shall be eligible to be granted Options or Stock Appreciation Rights whose value is determined by reference to an increase over an exercise or strike price of at least one hundred percent (100%) of the Fair Market Value on the date any such Stock Award is granted covering more than one million (1,000,000) shares of Common Stock during any calendar year.

(c)    Consultants. A Consultant shall not be eligible for the grant of a Stock Award if, at the time of grant, a Form S-8 Registration Statement under the Securities Act (“Form S-8”) is not available to register either the offer or the sale of the Company’s securities to such Consultant because of the nature of the services that the Consultant is providing to the Company, because the Consultant is not a natural person, or because of any other rule governing the use of Form S-8.

Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of each Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions:

(a)    Term. No Option shall be exercisable after the expiration of ten (10) years from the date on which it was granted.

(b)    Exercise Price of a Stock Option. The exercise price of each Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Sections 409A and 424(a) of the Code; provided, however, that if the Common Stock is listed on the Toronto Stock Exchange, the granting of the Option is approved by the Toronto Stock Exchange to the extent necessary to satisfy the rules of the Toronto Stock Exchange.

(c)    Consideration. The purchase price of Common Stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations, either (i) in cash at the time the Option is exercised or (ii) at the discretion of the Board at the time of or subsequently to the grant of the Option (1) by delivery to the Company of other Common Stock (whether by actual delivery or attestation), (2) by a “net exercise” of the Option (as further described below), (3) pursuant to a program developed under Regulation T as promulgated by the Federal

Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instruction to pay the aggregate exercise price to the Company from the sales proceeds or (4) in any other form of legal consideration that may be acceptable to the Board.

In the case of a “net exercise” of an Option, the Company will not require a payment of the exercise price of the Option from the Optionholder but will reduce the number of shares of Common Stock issued upon the exercise by the largest number of whole shares that has a Fair Market Value that does not exceed the aggregate exercise price. With respect to any remaining balance of the aggregate exercise price, the Company shall accept a cash payment from the Optionholder. The shares of Common Stock so used to pay the exercise price of an Option under a “net exercise,” the shares actually delivered to the Optionholder, and any shares withheld to satisfy tax withholding obligations will be considered to have resulted from the exercise of the Option, and accordingly, the Option will not again be exercisable with respect to such shares.

(d)    Transferability of an Option. An Option shall be transferable to the extent provided in the Option Agreement. If the Option does not provide for transferability, then the Option shall not be transferable except by will or by the laws of descent and distribution or pursuant a domestic relations order and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option. In no event shall an Option be transferred for value. A transfer for “value” shall not be deemed to occur under the Plan where an Option is transferred for bona fide estate planning purposes to a trust or other testamentary vehicle approved by the Committee.

(e)    Vesting Generally. The total number of shares of Common Stock subject to an Option may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The vesting provisions of individual Options may vary. The provisions of this Section 6(e) are subject to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be exercised.

(f)    Termination of Continuous Service. In the event that an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service (or such longer or shorter period specified in the Option Agreement) or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate.

(g)    Extension of Termination Date. An Optionholder’s Option Agreement may also provide that if the exercise of the Option following the termination of the Optionholder’s Continuous Service (other than upon the Optionholder’s death or Disability) would be prohibited at any time solely because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth in Section 6(a) or (ii) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during which the exercise of the Option would not be in violation of such registration requirements.

(h)    Disability of Optionholder. In the event that an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination), but only within such period of time

ending on the earlier of (i) the date twelve (12) months following such termination (or such longer or shorter period specified in the Option Agreement or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate.

(i)    Death of Optionholder. In the event that (i) an Optionholder’s Continuous Service terminates as a result of the Optionholder’s death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the Optionholder’s Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option upon the Optionholder’s death pursuant to Section 6(d), but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Option Agreement or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate.

(j)    Early Exercise. The Option may, but need not, include a provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. Any unvested shares of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be appropriate. The Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid classification of the Option as a liability for financial accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option.

(a)    Restricted Stock Awards. Each Restricted Stock Award agreement shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Common Stock may be (x) held in book entry form subject to the Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, which certificate shall be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award agreements may change from time to time, and the terms and conditions of separate Restricted Stock Award agreements need not be identical; provided, however, that each Restricted Stock Award agreement shall include (through incorporation of the provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

(i)    Purchase Price. At the time of the grant of a Restricted Stock Award, the Board will determine the price to be paid by the Participant for each share subject to the Restricted Stock Award. To the extent required by applicable law, the price to be paid by the Participant for each share of the Restricted Stock Award will not be less than the par value of a share of Common Stock. A Restricted Stock Award may be awarded as a stock bonus (i.e., with no cash purchase price to be paid) to the extent permissible under applicable law.

(ii)    Consideration. At the time of the grant of a Restricted Stock Award, the Board will determine the consideration permissible for the payment of the purchase price of the Restricted Stock Award. The purchase price of Common Stock acquired pursuant to the Restricted Stock Award shall be paid in one of the following ways: (i) in cash at the time of purchase; (ii) by services rendered or to be rendered to the Company; or (iii) in any other form of legal consideration that may be acceptable to the Board.

(iii)    Vesting. Shares of Common Stock acquired under a Restricted Stock Award may, but need not, be subject to a share repurchase option in favor of the Company in accordance with a vesting schedule to be determined by the Board.

(iv)    Termination of Participant’s Continuous Service. In the event that a Participant’s Continuous Service terminates, the Company may repurchase or otherwise reacquire any or all of the shares of Common Stock held by the Participant that have not vested as of the date of termination under the terms of the Restricted Stock Award agreement.

(v)    Dividend Equivalents. Dividend equivalents may be credited in respect of Restricted Stock Units, as the Board deems appropriate. Such dividend equivalents may be converted into additional Restricted Stock Units by dividing (1) the aggregate amount or value of the dividends paid with respect to that number of shares of Common Stock equal to the number of Restricted Stock Units then credited by (2) the Fair Market Value per share of Common Stock on the payment date for such dividend. The additional Restricted Stock Units credited by reason of such dividend equivalents will be subject to all the terms and conditions of the underlying Restricted Stock Unit award to which they relate.

(v)    Termination of Continuous Service. If a Participant’s Continuous Service terminates for any reason, any unvested Stock Appreciation Rights shall be forfeited and any vested Stock Appreciation Rights shall be automatically redeemed.

(d)    Other Stock Awards. Other forms of Stock Awards valued in whole or in part by reference to, or otherwise based on, Common Stock may be granted either alone or in addition to Stock Awards provided for under Section 6 and the preceding provisions of this Section 7.

If, after reasonable efforts, the Company is unable to obtain from any

such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such authority is obtained. A Participant shall not be eligible for the grant of a Stock Award or the subsequent issuance of Common Stock pursuant to the Stock Award if such grant or issuance would be in violation of any applicable securities law.

Corporate action constituting a grant by the Company of a Stock Award to any Participant shall be deemed completed as of the date of such corporate action, unless otherwise determined by the Board, regardless of when the instrument, certificate, or letter evidencing the Stock Award is communicated to, or actually received or accepted by, the Participant.

(c)    Stockholder Rights. Subject to the further limitations of Section 7(b)(iv) hereof, no Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Stock Award unless and until (i) such Participant has satisfied all requirements for exercise of the Stock Award pursuant to its terms, if applicable, and (ii) the issuance of the Common Stock subject to such Stock Award has been entered into the books and records of the Company.

(d)    No Employment or other Service Rights. Nothing in the Plan, and Stock Award Agreement or any other instrument executed thereunder or in connection with any Stock Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be.

(e)    Investment Assurances.

merits and risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Stock Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act, or (2) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

To the extent applicable, the Plan and Stock Award Agreements shall be interpreted in accordance with Section 409A of the Code, including without limitation any applicable guidance that may be issued or amended after the Effective Date.
