(i)     To select the individuals to whom Awards may from time to time be granted;

All decisions and interpretations of the Administrator shall be binding on all persons, including the Company and Plan grantees.

Notwithstanding the foregoing, the Administrator’s power and authority to make grants under the Plan shall be subject to the right of the Board, upon its request, to ratify Awards granted to the Chairman and other individuals specified by the Board, and in such event, the date of grant shall be the date of Board ratification.

(c) Delegation of Authority to Grant Awards. The Administrator, in its discretion, may delegate to the Company’s Chief Executive Officer, Chief Financial Officer, General Counsel, or Chief Human Resources Officer, or any person designated by the Board as an “executive officer” as defined in Rule 3b-7 under the Exchange Act all or part of the Administrator’s authority and duties with respect to the granting of Awards to individuals who are not subject to the reporting and other provisions of Section 16 of the Exchange Act. Any such delegation by the Administrator shall include a limitation as to the amount of Awards that may be granted during the period of the delegation and shall contain guidelines as to the determination of the exercise price of any Stock Option or Stock Appreciation Right, the conversion ratio or price of other Awards and the vesting criteria. The Administrator may revoke or amend the terms of a delegation at any time but such action shall not invalidate any prior actions of the Administrator’s delegate or delegates that were consistent with the terms of the Plan.

(d) Detrimental Activity. Unless the award agreement specifies otherwise, the Administrator may cancel, rescind, suspend, withhold or otherwise limit or restrict any Award (whether vested or unvested, exercised or unexercised) at any time if the recipient is not in compliance with all applicable provisions of the award agreement and the Plan, or if the recipient engages in any “Detrimental Activity.” For purposes of this Section 2, “Detrimental Activity” shall include: (i) the rendering of services for any organization or engaging directly or indirectly in any business which is or becomes competitive with the Company, or which organization or business, or the rendering of services to such organization or business, is or becomes otherwise prejudicial to or in conflict with the interests of the Company; (ii) the disclosure to anyone outside the Company, or the use in other than the Company’s business, without prior written authorization from the Company, of any confidential information or material, as defined in the Company’s employee confidentiality agreement or such other agreement regarding confidential information and intellectual property that the recipient and the Company may enter into (collectively, the “Confidentiality Agreement”), relating to the business of the Company, acquired by the recipient either during or after employment with the Company; (iii) the failure or refusal to disclose promptly and to assign to the Company, pursuant to the Confidentiality Agreement or otherwise, all right, title and interest in any invention or idea, patentable or not, made or conceived by the recipient during employment by the Company, relating in any manner to the actual or anticipated business, research or development work of the Company or the failure or refusal to do anything reasonably necessary to enable the Company to secure a patent where appropriate in the United States and in other countries; (iv) activity that results in termination of the recipient’s employment for cause; (v) a material violation of any rules, policies, procedures or guidelines of the Company; (vi) any attempt directly or indirectly to induce any employee of the Company to be employed or perform services elsewhere or any attempt directly or indirectly to solicit the trade or business of any current or prospective customer, supplier or partner of the Company; or (vii) the recipient being convicted of, or entering a guilty plea with respect to, a crime, whether or not connected with the Company.

(e) Indemnification. Neither the Board nor the Committee, nor any member of either or any delegate thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Committee (and any delegate thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, reasonable attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under any directors’ and officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification agreement between such individual and the Company.

SECTION 3.    STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

(a) Stock Issuable. The maximum number of shares of Stock reserved and available for issuance under the Plan shall be 5,862,000, plus the number of shares of Stock reserved and available for issuance under the Mercury Systems, Inc. Amended and Restated 2005 Stock Incentive Plan (the “2005 Stock Incentive Plan”) as of the date of shareholder approval of this Plan, subject to adjustment as provided in Section 3(c). For purposes of this limitation, the shares of Stock underlying any Awards that are forfeited, are canceled, expire or are terminated (other than by exercise) under (i) this Plan or (ii) from and after shareholder approval of this Plan, the 2005 Stock Incentive Plan shall be added to the shares of Stock available for issuance under this Plan. Shares tendered or held back upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding shall not be available for future issuance under the Plan. In addition, upon exercise of Stock Appreciation Rights, the gross number of shares exercised shall be deducted from the total number of shares remaining available for issuance under the Plan. Also, shares purchased in the open market using proceeds received upon the exercise of an Option shall not be available for future issuance under the Plan. Subject to such overall limitations and Section 3(c), shares of Stock may be issued up to such maximum number pursuant to any type or types of Award; provided, however, that Stock Options or Stock Appreciation Rights with respect to no more than 500,000 shares of Stock may be granted to any one individual grantee during any one calendar year period and provided, further, that in no event may Incentive Stock Options granted under the Plan exceed 5,862,000 shares of Stock. The shares available for issuance under the Plan may be authorized but unissued shares of Stock or shares of Stock reacquired by the Company.

(b) Effect of Awards. The grant of any full value Award (i.e., an Award other than an Option or a Stock Appreciation Right) shall be deemed, for purposes of determining the number of shares available for issuance under Section 3(a), as an Award of two (2) shares of Stock for each such share actually subject to the Award. The grant of an Option or a Stock Appreciation Right shall be deemed, for purposes of determining the number of shares available for issuance under Section 3(a), as an Award of one (1) share of Stock for each such share actually subject to the Award.

(c) Changes in Stock. Subject to Section 3(d) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar

change in the Company’s capital stock, the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Stock or other securities, or, if, as a result of any merger or consolidation, sale of all or substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for a different number or kind of securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall make an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, including the maximum number of shares that may be issued in the form of Incentive Stock Options, (ii) the number of Stock Options or Stock Appreciation Rights that can be granted to any one individual grantee and the maximum number of shares that may be granted under a Performance-based Award, (iii) the number and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iv) the repurchase price, if any, per share subject to each outstanding Restricted Stock Award, and (v) the price for each share subject to any then outstanding Stock Options and Stock Appreciation Rights under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options and Stock Appreciation Rights) as to which such Stock Options and Stock Appreciation Rights remain exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of shares subject to outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any other extraordinary corporate event. The adjustment by the Administrator shall be final, binding and conclusive. No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional shares.

(d) Mergers and Other Transactions. In the case of and subject to the consummation of (i) the dissolution or liquidation of the Company, (ii) the sale of all or substantially all of the assets of the Company on a consolidated basis to an unrelated person or entity, (iii) a merger, reorganization or consolidation in which the outstanding shares of Stock are converted into or exchanged for a different kind of securities of the successor entity and the holders of the Company’s outstanding voting power immediately prior to such transaction do not own a majority of the outstanding voting power of the successor entity immediately upon completion of such transaction, or (iv) the sale of all of the Stock of the Company to an unrelated person or entity (in each case, a “Sale Event”), the Plan and all outstanding Awards granted hereunder shall terminate, unless provision is made in connection with the Sale Event in the sole discretion of the parties thereto for the assumption or continuation of Awards theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree (after taking into account any acceleration hereunder). In the event of such termination, each grantee shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to exercise all outstanding vested and exercisable Options and Stock Appreciation Rights held by such grantee.

Notwithstanding anything to the contrary in this Section 3(d), in the event of a Sale Event pursuant to which holders of the Stock of the Company will receive upon consummation thereof a cash payment for each share surrendered in the Sale Event, the Company shall have the right, but not the obligation, to make or provide for a cash payment to the grantees holding vested and exercisable Options and Stock Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the value as determined by the Administrator of the consideration payable per share of Stock pursuant to the Sale Event (the “Sale Price”) times the number of shares of Stock subject to such outstanding Options and Stock Appreciation Rights (to the extent then exercisable at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding Options and Stock Appreciation Rights.

(e) Substitute Awards. The Administrator may grant Awards under the Plan in substitution for stock and stock based awards held by employees, directors or other key persons of another corporation in connection with the merger or consolidation of the employing corporation with the Company or a Subsidiary or the acquisition by the Company or a Subsidiary of property or stock of the employing corporation. The Administrator may direct that the substitute awards be granted on such terms and conditions as the Administrator considers appropriate in the circumstances. Any substitute Awards granted under the Plan shall not count against the share limitation set forth in Section 3(a).

SECTION 4.    ELIGIBILITY

Grantees under the Plan will be such full- or part-time officers and other employees, Non-Employee Directors and key persons (including consultants and qualified individuals who have received offers of employment) of the Company and its Subsidiaries as are selected from time to time by the Administrator in its sole discretion.

SECTION 5.     STOCK OPTIONS

(a) Grant of Stock Options. Any Stock Option granted under the Plan shall be in such form as the Administrator may from time to time approve.

Stock Options granted under the Plan may be either Incentive Stock Options or Non-Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option.

Stock Options granted pursuant to this Section 5(a) shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable. Stock Options may be granted in lieu of cash compensation at the optionee’s election, subject to such terms and conditions as the Administrator may establish. No dividends or dividend equivalents shall be paid on Options.

(b) Exercise Price. The exercise price per share for the Stock covered by a Stock Option granted pursuant to this Section 5(a) shall be determined by the Administrator at the time of grant but shall not be less than 100 percent (100%) of the Fair Market Value on the date of grant.

(c) Option Term. The term of each Stock Option shall be fixed by the Administrator, but no Stock Option shall be exercisable more than seven (7) years after the date the Stock Option is granted.

(d) Exercisability; Rights of a Shareholder. Stock Options shall become exercisable at such time or times, whether or not in installments, as shall be determined by the Administrator at or after the grant date. An optionee shall have the rights of a shareholder only as to shares acquired upon the exercise of a Stock Option and not as to unexercised Stock Options.

(e) Method of Exercise. Stock Options may be exercised in whole or in part, by giving written notice of exercise to the Company, specifying the number of shares to be purchased; provided, however, that no Stock Option may be partially exercised with respect to fewer than 50 (fifty) shares. Payment of the purchase price may be made by one or more of the following methods to the extent provided in the Option Award agreement:

(i)In cash, by certified or bank check or other instrument acceptable to the Administrator;

(ii)Through the delivery (or attestation to the ownership) of shares of Stock that have been purchased by the optionee on the open market or that are beneficially owned by the optionee and are not then subject to restrictions under any Company plan. Such surrendered shares shall be valued at Fair Market Value on the exercise date;

(iii)By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; or

(iv)By the optionee delivering to the Company a properly executed net exercise notice. Such shares withheld by the Company in the net exercise shall be valued at Fair Market Value on the exercise date.

Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer agent of the shares of Stock to be purchased pursuant to the exercise of a Stock Option will be contingent upon receipt from the optionee (or a purchaser acting in his stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Option Award agreement or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is obligated to withhold with respect to the optionee). In the event an optionee chooses to pay the purchase price by previously-owned

shares of Stock through the attestation method, the number of shares of Stock transferred to the optionee upon the exercise of the Stock Option shall be net of the number of shares attested to.

(f) Annual Limit on Incentive Stock Options. To the extent required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the time of grant) of the shares of Stock with respect to which Incentive Stock Options granted under this Plan and any other plan of the Company or its parent and subsidiary corporations become exercisable for the first time by an optionee during any calendar year shall not exceed one hundred thousand dollars ($100,000). To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option.

(g) Restrictions. Stock Options may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Option Award agreement. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, if any, if a grantee’s employment (or other service relationship) with the Company and its Subsidiaries terminates for any reason, any Stock Options that have not vested at the time of termination shall automatically and without any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price from such grantee or such grantee’s legal representative simultaneously with such termination of employment (or other service relationship).

(h) Vesting of Stock Options. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Stock Options and the Company’s right of repurchase or risk of forfeiture shall lapse. In the event that any such Stock Options granted to employees shall have a performance-based goal, the vesting period with respect to such options shall not be less than one (1) year, and in the event that any such Stock Options granted to employees shall have a time-based restriction, the total vesting period with respect to such options shall not be less than three years; provided, however, that Stock Options granted to employees with a time-based restriction may become vested incrementally over such three-year period. No portion of any Stock Options granted to employees may vest prior to the first anniversary of the grant date. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the rights on which all restrictions have lapsed shall no longer be restricted and shall be deemed “vested.” Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, a grantee’s rights in any Stock Options that have not vested shall automatically terminate upon the grantee’s termination of employment (or other service relationship) with the Company and its Subsidiaries and such options shall be subject to the provisions of Section 5(g) above.

Notwithstanding the foregoing, the Administrator may accelerate the vesting of Stock Options granted to an employee in the case of retirement, death or disability.

SECTION 6. STOCK APPRECIATION RIGHTS

(a) Nature of Stock Appreciation Rights. A Stock Appreciation Right is an Award entitling the recipient to receive shares of Stock having a value equal to the excess of the Fair Market Value of the Stock on the date of exercise over the exercise price of the Stock Appreciation Right, which price shall not be less than 100 percent of the Fair Market Value of the Stock on the date of grant (or more than the option exercise price per share, if the Stock Appreciation Right was granted in tandem with a Stock Option) multiplied by the number of shares of Stock with respect to which the Stock Appreciation Right shall have been exercised. No dividends or dividend equivalents shall be paid on Stock Appreciation Rights.

(b) Grant and Exercise of Stock Appreciation Rights. Stock Appreciation Rights may be granted by the Administrator in tandem with, or independently of, any Stock Option granted pursuant to Section 5 of the Plan. In the case of a Stock Appreciation Right granted in tandem with a Non-Qualified Stock Option, such Stock Appreciation Right may be granted either at or after the time of the grant of such Option. In the case of a Stock Appreciation Right granted in tandem with an Incentive Stock Option, such Stock Appreciation Right may be granted only at the time of the grant of the Option.

A Stock Appreciation Right or applicable portion thereof granted in tandem with a Stock Option shall terminate and no longer be exercisable upon the termination or exercise of the related Option.

(c) Terms and Conditions of Stock Appreciation Rights. Stock Appreciation Rights shall be subject to such terms and conditions as shall be determined from time to time by the Administrator, subject to the following:

(i)Stock Appreciation Rights granted in tandem with Options shall be exercisable at such time or times and to the extent that the related Stock Options shall be exercisable; provided, however, that no Stock Appreciation Right may be partially exercised with respect to fewer than fifty (50) shares.

(ii)Upon exercise of a Stock Appreciation Right granted in tandem with an Option, the applicable portion of any related Option shall be surrendered.

(iii)     The term of a Stock Appreciation Right may not exceed seven (7) years.

(d) Restrictions. Stock Appreciation Rights may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Stock Appreciation Rights Award agreement. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, if any, if a grantee’s employment (or other service relationship) with the Company and its Subsidiaries terminates for any reason, any Stock Appreciation Rights that have not vested at the time of termination shall automatically and without any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed to have

been reacquired by the Company at its original purchase price from such grantee or such grantee’s legal representative simultaneously with such termination of employment (or other service relationship).

(e) Vesting of Stock Appreciation Rights. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Stock Appreciation Rights and the Company’s right of repurchase or risk of forfeiture shall lapse. In the event that any such Stock Appreciation Rights granted to employees shall have a performance-based goal, the vesting period with respect to such rights shall not be less than one (1) year, and in the event that any such Stock Appreciation Rights granted to employees shall have a time-based restriction, the total vesting period with respect to such rights shall not be less than three years; provided, however, that Stock Appreciation Rights granted to employees with a time-based restriction may become vested incrementally over such three-year period. No portion of any Stock Appreciation Rights granted to employees may vest prior to the first anniversary of the grant date. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the rights on which all restrictions have lapsed shall no longer be restricted and shall be deemed “vested.” Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, a grantee’s rights in any Stock Appreciation Rights that have not vested shall automatically terminate upon the grantee’s termination of employment (or other service relationship) with the Company and its Subsidiaries and such rights shall be subject to the provisions of Section 6(d) above.

Notwithstanding the foregoing, the Administrator may accelerate the vesting of Stock Appreciation Rights granted to an employee in the case of retirement, death or disability.

SECTION 7. RESTRICTED STOCK AWARDS

(a) Nature of Restricted Stock Awards. A Restricted Stock Award is an Award entitling the recipient to acquire, at such purchase price (which may be zero) as determined by the Administrator, shares of Stock subject to such restrictions and conditions as the Administrator may determine at the time of grant (“Restricted Stock”). Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The grant of a Restricted Stock Award is contingent on the grantee executing the Restricted Stock Award agreement. The terms and conditions of each such agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

(b) Rights as a Shareholder. Upon execution of a written instrument setting forth the Restricted Stock Award and payment of any applicable purchase price, a grantee shall have the rights of a shareholder with respect to the voting of the Restricted Stock, subject to such conditions contained in the written instrument evidencing the Restricted Stock Award. Unless the Administrator shall otherwise determine, (i) uncertificated Restricted Stock shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are

subject to forfeiture until such Restricted Stock are vested as provided in Section 7(d) below, and (ii) certificated Restricted Stock shall remain in the possession of the Company until such Restricted Stock is vested as provided in Section 7(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company such instruments of transfer as the Administrator may prescribe. Cash dividends and stock dividends, if any, with respect to the Restricted Stock shall be withheld by the Company for the grantee’s account, and shall be subject to forfeiture to the same degree as the shares of Restricted Stock to which such dividends relate. Except as otherwise determined by the Committee, no interest will accrue or be paid on the amount of any cash dividends withheld.

(c) Restrictions. Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided herein or in the Restricted Stock Award agreement. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, if any, if a grantee’s employment (or other service relationship) with the Company and its Subsidiaries terminates for any reason, any Restricted Stock that has not vested at the time of termination shall automatically and without any requirement of notice to such grantee from or other action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price from such grantee or such grantee’s legal representative simultaneously with such termination of employment (or other service relationship), and thereafter shall cease to represent any ownership of the Company by the grantee or rights of the grantee as a shareholder. Following such deemed reacquisition of unvested Restricted Stock that are represented by physical certificates, a grantee shall surrender such certificates to the Company upon request without consideration.

(d) Vesting of Restricted Stock. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the non-transferability of the Restricted Stock and the Company’s right of repurchase or risk of forfeiture shall lapse. In the event that any such Restricted Stock granted to employees shall have a performance-based goal, the restriction period with respect to such shares shall not be less than one (1) year, and in the event that any such Restricted Stock granted to employees shall have a time-based restriction, the total restriction period with respect to such shares shall not be less than three years; provided, however, that Restricted Stock granted to employees with a time-based restriction may become vested incrementally over such three-year period. No portion of any Restricted Stock granted to employees may vest prior to the first anniversary of the grant date. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the shares on which all restrictions have lapsed shall no longer be Restricted Stock and shall be deemed “vested.” Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is issued, a grantee’s rights in any shares of Restricted Stock that have not vested shall automatically terminate upon the grantee’s termination of employment (or other service relationship) with the Company and its Subsidiaries and such shares shall be subject to the provisions of Section 7(c) above.

Notwithstanding the foregoing, the Administrator may accelerate the vesting of Restricted Stock granted to an employee in the case of retirement, death or disability.

SECTION 8. DEFERRED STOCK AWARDS

(a) Nature of Deferred Stock Awards. A Deferred Stock Award is an Award of phantom stock units to a grantee, subject to restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on continuing employment (or other service relationship) and/or achievement of pre-established performance goals and objectives. The grant of a Deferred Stock Award is contingent on the grantee executing the Deferred Stock Award agreement. The terms and conditions of each such agreement shall be determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees. In the event that any such Deferred Stock Award granted to employees shall have a performance-based goal, the restriction period with respect to such award shall not be less than one (1) year, and in the event any such Deferred Stock Award shall have a time-based restriction, the total restriction period with respect to such award shall not be less than three (3) years; provided, however, that any Deferred Stock Award with a time-based restriction may become vested incrementally over such three (3) year period. No portion of any Deferred Stock Award granted to employees may vest prior to the first anniversary of the grant date. At the end of the deferral period, the Deferred Stock Award, to the extent vested, shall be paid to the grantee in the form of shares of Stock.

Notwithstanding the foregoing, the Administrator may accelerate the vesting of a Deferred Stock Award granted to an employee in the case of retirement, death or disability.

(b) Election to Receive Deferred Stock Awards in Lieu of Compensation. The Administrator may, in its sole discretion, permit a grantee to elect to receive a portion of future cash compensation otherwise due to such grantee in the form of a Deferred Stock Award. Any such election shall be made in writing and shall be delivered to the Company no later than the date specified by the Administrator and in accordance with Section 409A and such other rules and procedures established by the Administrator. The Administrator shall have the sole right to determine whether and under what circumstances to permit such elections and to impose such limitations and other terms and conditions thereon as the Administrator deems appropriate. Any deferred compensation shall be converted to a fixed number of phantom stock units based on the Fair Market Value of Stock on the date the compensation would otherwise have been paid but for the deferral.

(c) Rights as a Shareholder. During the deferral period, a grantee shall have no rights as a shareholder; provided, however, that the grantee may be credited with dividend equivalent rights with respect to the phantom stock units underlying his Deferred Stock Award, subject to such terms and conditions as the Administrator may determine, but shall not be entitled to dividends, if any, or dividend equivalents prior to settlement.

(d) Termination. Except as may otherwise be provided by the Administrator either in the Award agreement or, subject to Section 15 below, in writing after the Award agreement is

issued, a grantee’s right in all Deferred Stock Awards that have not vested shall automatically terminate upon the grantee’s termination of employment (or cessation of service relationship) with the Company and its Subsidiaries for any reason.

SECTION 9. PERFORMANCE-BASED AWARDS

(a) Performance Criteria. The performance criteria used in performance goals governing Performance-based Awards may include any or all of the following criteria at the Company, Subsidiary, business unit or business segment level as appropriate: (i) the Company’s return on equity, assets, capital or investment: (ii) pre-tax or after-tax profit levels or EBITDA or adjusted EBITDA; (iii) bookings or revenue growth; (iv) bookings or revenues; (v) operating income as a percentage of sales; (vi) total shareholder return; (vii) changes in the market price of the Stock; (viii) sales or market share; (ix) earnings per share; (x) improvements in operating margins; (xi) operating cash flow or free cash flow; (xii) working capital improvements; (xiii) design wins or entering into contracts with key customers; and (xiv) any combination of such performance metrics, comparisons of such performance metrics to corresponding metrics used by other companies or comparison of such performance metrics to industry data.

(b) Grant of Performance-based Awards. With respect to each Performance-based Award, the Committee shall select, within the first ninety (90) days of a Performance Cycle the performance criteria for such grant, and the achievement targets with respect to each performance criterion (including a threshold level of performance below which no amount will become payable with respect to such Award). Each Performance-based Award will specify the amount payable, or the formula for determining the amount payable, upon achievement of the various applicable performance targets. The performance criteria established by the Committee may be (but need not be) different for each Performance Cycle and different goals may be applicable to Performance-based Awards to different grantees.

(c) Payment of Performance-based Awards. Following the completion of a Performance Cycle, the Committee shall meet to review and certify in writing whether, and to what extent, the performance criteria for the Performance Cycle have been achieved and, if so, to also calculate and certify in writing the amount of the Performance-based Awards earned for the Performance Cycle. The Committee shall then determine the actual size of each grantee’s Performance-based Award.

SECTION 10. TRANSFERABILITY OF AWARDS

(a) Transferability. Except as provided in Section 10(b) below, during a grantee’s lifetime, his or her Awards shall be exercisable only by the grantee, or by the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall be sold, assigned, transferred or otherwise encumbered or disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards shall be subject, in whole or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void.

(b) Committee Action. Notwithstanding Section 10(a), the Administrator, in its discretion, may provide either in the Award agreement regarding a given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Awards (other than any Incentive Stock Options) to his or her immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award.

(c) Family Member. For purposes of Section 10(b), “family member” shall mean a grantee’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the grantee’s household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than fifty percent (50%) of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which these persons (or the grantee) own more than fifty percent (50%) of the voting interests.

(d) Designation of Beneficiary. Each grantee to whom an Award has been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate.

SECTION 11. TAX WITHHOLDING

(a) Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Stock or other amounts received thereunder first becomes includable in the gross income of the grantee for federal income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any federal, state, or local taxes of any kind required or permitted by law to be withheld by the Company with respect to such income. The Company and its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The Company’s obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being satisfied by the grantee.

(b) Payment in Stock. Subject to approval by the Administrator, depending on the withholding method, a grantee may elect to have such grantee’s tax withholding obligation satisfied at the minimum or other applicable withholding rate in the grantee’s applicable jurisdiction, including maximum applicable rates that may be utilized without creating adverse accounting treatment under Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor pronouncement thereto) and permitted under applicable withholding rules promulgated by the Internal Revenue Service or another applicable governmental entity, in whole or in part, by (i) authorizing the Company to withhold from shares

of Stock to be issued pursuant to any Award a number of shares with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy such withholding amount, or (ii) transferring to the Company shares of Stock owned by the grantee with an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy such withholding amount.

SECTION 12. CHANGE OF CONTROL

(a) Occurrence of Change of Control. If within six months following the consummation of a Change of Control of the Company, as defined in Section 12(b)(i), the employment of a grantee with a minimum of six months of service with the Company or any of its Subsidiaries as of the effective date of such Change of Control (the “Effective Date”) is involuntarily terminated, then (i) if such Change of Control does not constitute a Sale Event, 100% of the unvested Awards of such grantee will automatically be fully vested, (ii) if such Change of Control constitutes a Sale Event and provision is made for the assumption or continuation of Awards hereunder, or the substitution of such Awards with new Awards of the successor entity or parent thereof, 100% of the unvested assumed, continued or substituted Awards will automatically be fully vested, and (iii) if such Change of Control constitutes a Sale Event and provision is not made for the assumption, continuation or substitution of Awards hereunder, such that all of the unvested Awards of such grantee terminated upon consummation of the Sale Event without any payment with respect thereto, the grantee will be entitled to receive a cash payment equal to the difference between (x) the Sale Price multiplied by the number of shares of Stock subject to 100% of such grantee’s unvested Awards as of the consummation of the Sale Event and (y) the aggregate exercise price of such unvested Awards. Notwithstanding the foregoing, in the event that the fair market value (less any exercise price) of the Awards subject to automatic vesting or any cash payment to which the grantee may become entitled in accordance with the preceding sentence exceeds $25,000 as of the date of termination of employment, then such vesting or payment shall be conditioned upon the grantee executing and failing to revoke during any applicable revocation period a general release of all claims against the Company and its Subsidiaries and affiliates in a form acceptable to the Company or its successor within 60 days of such termination. For purposes hereof, a grantee’s employment with the Company or any Subsidiary is considered “involuntarily terminated” if the Company or any Subsidiary terminates such grantee’s employment with the Company or such Subsidiary without Cause, as defined in Section 12(b)(ii), or such grantee resigns his or her employment with the Company or such Subsidiary for Good Reason, as defined in Section 12(b)(iii). Notwithstanding the foregoing, in the event the Change of Control of the Company is not approved by the Board of Directors, all of the outstanding Awards will automatically become fully vested upon the consummation of the Change of Control of the Company. Further, all of the outstanding Awards held by Non-Employee Directors will automatically become fully vested upon the consummation of a Change of Control of the Company.

(b) Definitions. For purposes of the Plan:

(i)A “Change of Control of the Company” shall be deemed to have occurred by the Committee, in its sole discretion, upon the occurrence of any of the following events:

(A)     Any “Person,” as such term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all “affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Exchange Act) of such person, shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing thirty percent (30%) or more of the combined voting power of the Company’s then outstanding securities having the right to vote in an election of the Company’s Board of Directors (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from the Company or an acquisition of securities involving a Corporate Transaction of the type described in the exclusion set forth in clause (C) below); or

(B)     Persons who, as of the date hereof, constitute the Company’s Board of Directors (the “Incumbent Directors”) cease for any reason, including, without limitation, as a result of a tender offer, proxy contest, merger or similar transaction, to constitute at least a majority of the Board, provided that any person becoming a director of the Company subsequent to the date hereof shall be considered an Incumbent Director if such person’s election was approved by or such person was nominated for election by either (x) a vote of at least a majority of the Incumbent Directors or (y) a vote of at least a majority of the Incumbent Directors who are members of a nominating committee comprised, in the majority, of Incumbent Directors; but provided further, that any such person whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of members of the Board of Directors or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Board, including by reason of agreement intended to avoid or settle any such actual or threatened contest or solicitation, shall not be considered an Incumbent Director; or

(C)     The consummation of a consolidation, merger or consolidation or sale or other disposition of all or substantially all of the assets of the Company (a “Corporate Transaction”); excluding, however, a Corporate Transaction in which the shareholders of the Company immediately prior to the Corporate Transaction, would, immediately after the Corporate Transaction, beneficially own (as such term is defined in Rule 13d-3 under the Exchange Act), directly or indirectly, shares representing in the aggregate more than fifty percent (50%) of the voting shares of the corporation

issuing cash or securities in the Corporate Transaction (or of its ultimate parent corporation, if any).

Notwithstanding the foregoing, (i) a “Change of Control of the Company” shall not be deemed to have occurred for purposes of the foregoing clause (A) solely as the result of an acquisition of securities by the Company that, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of shares of Voting Securities beneficially owned by any person to thirty percent (30%) or more of the combined voting power of all then outstanding Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns thirty percent (30%) or more of the combined voting power of all then outstanding Voting Securities, then a “Change of Control of the Company” shall be deemed to have occurred for purposes of the foregoing clause (A) and (ii) for any Awards subject to the requirements of Section 409A of the Code that will become payable on a Change of Control of the Company, the transaction constituting a “Change of Control” must also constitute a “change in control event” for purposes of Section 409A(a)(2)(A)(v) of the Code.

(ii)     “Cause” shall mean (A) conduct by the grantee constituting a material act of willful misconduct in connection with the performance of his or her duties, including, without limitation, misappropriation of funds or property of the Company or any of its Subsidiaries other than the occasional, customary and de minimis use of the Company or its Subsidiaries’ property for personal purposes; (B) the commission by the grantee of any felony or a misdemeanor involving moral turpitude, deceit, dishonesty or fraud, or any conduct by the grantee that would reasonably be expected to result in material injury to the Company or any of its Subsidiaries; (C) the grantee’s willful and continued failure to perform his or her duties with the Company and its Subsidiaries (other than any failure resulting from incapacity due to physical or mental illness), which continues thirty (30) days after a written demand of performance is delivered to the grantee by any Senior Vice President or Vice President of the Company, which identifies the manner in which such person believes that the grantee has not performed his or her duties; (D) a violation by the grantee of the employment policies of the Company and its Subsidiaries which has continued following written notice of such violation from any Senior Vice President or Vice President of the Company; or (E) the grantee’s willful failure to cooperate with a bona fide internal investigation or an investigation by regulatory or law enforcement authorities, after being instructed by the Company or any of its Subsidiaries to cooperate, or the willful destruction or failure to preserve documents or other materials known to be relevant to such investigation or the willful inducement of others to fail to cooperate or to produce documents or other materials.

(iii)     “Good Reason ” shall mean (A) a reduction in the grantee’s annual cash base salary as in effect on the Effective Date, except for across-the-board reductions similarly affecting all or substantially all Company employees; or (B) a relocation whereby the Company or any Subsidiary requires the grantee to be principally based at any office or location that is more than fifty (50) miles from the grantee’s office on the Effective Date; provided that the reasons set forth above will not constitute “Good Reason” unless, within thirty (30) days after the first occurrence of such Good Reason event, the grantee shall have given written notice to the Company specifically identifying the event that the grantee believes constitutes Good Reason and the Company, or, if applicable, its Subsidiary, has not remedied such event within a reasonable cure period of not less than thirty (30) days after the Company’s receipt of such notice.

SECTION 13. Additional Conditions Applicable to Nonqualified Deferred Compensation Under Section 409A.

In the event any Stock Option or Stock Appreciation Right under the Plan is granted with an exercise price of less than one hundred percent (100%) of the Fair Market Value on the date of grant (regardless of whether or not such exercise price is intentionally or unintentionally priced at less than Fair Market Value), or such grant is materially modified and deemed a new grant at a time when the Fair Market Value exceeds the exercise price, or any other Award is otherwise determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code (a “409A Award”), the following additional conditions shall apply and shall supersede any contrary provisions of this Plan or the terms of any agreement relating to such 409A Award.

(a) Exercise and Distribution. Except as provided in Section 13(b) hereof, no 409A Award shall be exercisable or distributable earlier than upon one of the following:

(ii)Separation from Service. Separation from service (within the meaning of Section 409A) by the 409A Award grantee; provided, however, that if the 409A Award grantee is a “key employee” (as defined in Section 416(i) of the Code without regard to paragraph (5) thereof) and any of the Company’s Stock is publicly traded on an established securities market or otherwise, exercise or distribution under this Section 13(a)(ii) may not be made before the date that is six months after the date of separation from service.

(iii)Death. The date of death of the 409A Award grantee.

(v)Unforeseeable Emergency. The occurrence of an unforeseeable emergency (within the meaning of Section 13(c)(iii) hereof), but only if the net value (after payment of the exercise price) of the number of shares of Stock that become issuable does not exceed the amounts necessary to satisfy such emergency plus amounts necessary to pay taxes reasonably anticipated as a result of the exercise, after taking into account the extent to which the emergency is or may be relieved through reimbursement or compensation by insurance or otherwise or by liquidation of the grantee’s other assets (to the extent such liquidation would not itself cause severe financial hardship).

(vi)Change of Control Event. The occurrence of a Change of Control Event (within the meaning of Section 13(c)(i) hereof), including the Company’s discretionary exercise of the right to accelerate vesting of such grant upon a Change of Control Event or to terminate the Plan or any 409A Award granted hereunder within twelve (12) months of the Change of Control Event.

(b) No Acceleration. A 409A Award may not be accelerated or exercised prior to the time specified in Section 13(a) hereof, except in the case of one (1) of the following events:

(i)Domestic Relations Order. The 409A Award may permit the acceleration of the exercise or distribution time or schedule to an individual other than the grantee as may be necessary to comply with the terms of a domestic relations order (as defined in Section 414(p)(1)(B) of the Code).

(ii)Conflicts of Interest. The 409A Award may permit the acceleration of the exercise or distribution time or schedule as may be necessary to comply with the terms of a certificate of divestiture (as defined in Section 1043(b)(2) of the Code).

(iii)Change of Control Event. The Administrator may exercise the discretionary right to accelerate the vesting of such 409A Award upon a Change of Control Event or to terminate the Plan or any 409A Award granted thereunder within twelve (12) months of the Change of Control Event and cancel the 409A Award for compensation.

(c) Definitions. Solely for purposes of this Section 13 and not for other purposes of the Plan, the following terms shall be defined as set forth below:

(i)     “Change of Control Event” means the occurrence of a change in the ownership of the Company, a change in effective control of the Company, or a change in the ownership of a substantial portion of the assets of the Company (as defined in regulations promulgated under Section 409A).

(ii)     “Disabled” means a grantee who (i) is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 (twelve) months, or (ii) is, by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) (twelve) months, receiving income replacement benefits for a period of not less than three (3) months under an accident and health plan covering employees of the Company or its Subsidiaries.

(iii)     “Unforeseeable Emergency” means a severe financial hardship to the grantee resulting from an illness or accident of the grantee, the grantee’s spouse, or a dependent (as defined in Section 152(a) of the Code) of the grantee, loss of the grantee’s property due to casualty, or similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the grantee.

SECTION 14. TRANSFER, LEAVE OF ABSENCE, ETC.

For purposes of the Plan, the following events shall not be deemed a termination of employment:

(a)     A transfer to the employment of the Company from a Subsidiary or from the Company to a Subsidiary, or from one Subsidiary to another; or

(b)     An approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing.

SECTION 15. AMENDMENTS AND TERMINATION

(a)Amendments in General. The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the holder’s consent. Except as provided in Section 3(c) or 3(d), in no event may the Administrator exercise its discretion to reduce the exercise price of outstanding Stock Options or Stock Appreciation Rights, effect repricing through cancellation and re-grants, or repurchase out-of-the-money Stock Options or Stock Appreciation Rights for cash, unless the Administrator proposes for shareholder vote, and shareholders approve, such reduction, cancellation and re-grant, repricing, or repurchase. Any material Plan amendments (other than amendments that curtail the scope of the Plan),

including any Plan amendments that (i) increase the number of shares reserved for issuance under the Plan, (ii) expand the type of Awards available under, materially expand the eligibility to participate in, or materially extend the term of, the Plan, or (iii) materially change the method of determining Fair Market Value, shall be subject to approval by the Company shareholders entitled to vote at a meeting of shareholders. In addition, to the extent determined by the Administrator to be required by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code or to ensure that compensation earned under Awards qualifies as performance-based compensation under Section 162(m) of the Code, Plan amendments shall be subject to approval by the Company shareholders entitled to vote at a meeting of shareholders. Nothing in this Section 15 shall limit the Administrator’s authority to take any action permitted pursuant to Section 3(c) or 3(d).

(b)No Repricing of Awards Without Stockholder Approval. Notwithstanding any other provision of the Plan, the repricing of Awards shall not be permitted without stockholder approval. For this purpose, a “repricing” means any of the following (or any other action that has the same effect as any of the following): (1) changing the terms of an Award to lower its exercise or base price (other than on account of capital adjustments resulting from share splits, etc., as described herein, (2) any other action that is treated as a repricing under GAAP, and (3) repurchasing for cash or canceling an Award in exchange for another Award at a time when its exercise or base price is greater than the Fair Market Value of the underlying share of Stock, unless the cancellation and exchange occurs in connection with an event set forth in Section 3 hereof.

With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in connection with any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company’s obligations to deliver Stock or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing sentence.

SECTION 16. GENERAL PROVISIONS

(a) No Distribution; Compliance with Legal Requirements. The Administrator may require each person acquiring Stock pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the shares without a view to distribution thereof.

No shares of Stock shall be issued pursuant to an Award until all applicable securities law and other legal and stock exchange or similar requirements have been satisfied. The Administrator may require the placing of such stop-orders and restrictive legends on certificates for Stock and Awards as it deems appropriate.

(b) Delivery of Stock Certificates. Stock certificates to grantees under this Plan shall be deemed delivered for all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company. Uncertificated Stock shall be deemed delivered for all purposes when the Company or a Stock transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records). Stock Certificates or uncertified Stock for any Restricted Stock Award shall be delivered to the Secretary of the Company to be held in escrow until the Award becomes vested.

(c) Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary.

(d) Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to such Company’s applicable insider trading policy and procedures, as in effect from time to time.

(e) Grantees Outside of the United States. The Committee may modify the terms of any Award under the Plan made to or held by a grantee who is then a resident, or is primarily employed or providing services, outside of the United States in any manner deemed by the Committee to be necessary or appropriate in order that such Award shall conform to laws, regulations, and customs of the country in which the grantee is then a resident or primarily employed or providing services, or so that the value and other benefits of the Award to the grantee, as affected by non–U.S. tax laws and other restrictions applicable as a result of the grantee’s residence, employment, or providing services abroad, shall be comparable to the value of such Award to a grantee who is a resident, or is primarily employed or providing services, in the United States. An Award may be modified under this Section 17(e) in a manner that is inconsistent with the express terms of the Plan, so long as such modifications will not contravene any applicable law or regulation or result in actual liability under Section 16(b) of the Exchange Act for the grantee whose Award is modified. Additionally, the Committee may adopt such procedures and sub-plans as are necessary or appropriate to permit participation in the Plan by Eligible Persons who are non–U.S. nationals or are primarily employed or providing services outside the United States.

(f) Data Privacy. As a condition of receipt of any Award, each grantee explicitly and unambiguously consents to the collection, use, and transfer, in electronic or other form, of personal data as described in this Section 17(f) by and among, as applicable, the Company and its Affiliates for the exclusive purpose of implementing, administering, and managing the Plan and Awards and the grantee’s participation in the Plan. In furtherance of such implementation, administration, and management, the Company and its Affiliates may hold certain personal information about a grantee, including, but not limited to, the grantee’s name, home address,

telephone number, date of birth, social security or insurance number or other identification number, salary, nationality, job title(s), information regarding any securities of the Company or any of its Affiliates, and details of all Awards (the “Data”). In addition to transferring the Data amongst themselves as necessary for the purpose of implementation, administration, and management of the Plan and Awards and the grantee’s participation in the Plan, the Company and its Affiliates may each transfer the Data to any third parties assisting the Company in the implementation, administration, and management of the Plan and Awards and the grantee’s participation in the Plan. Recipients of the Data may be located in the grantee’s country or elsewhere, and the grantee’s country and any given recipient’s country may have different data privacy laws and protections. By accepting an Award, each grantee authorizes such recipients to receive, possess, use, retain, and transfer the Data, in electronic or other form, for the purposes of assisting the Company in the implementation, administration, and management of the Plan and Awards and the grantee’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom the Company or the grantee may elect to deposit any shares of Stock. The Data related to a grantee will be held only as long as is necessary to implement, administer, and manage the Plan and Awards and the grantee’s participation in the Plan. A grantee may, at any time, view the Data held by the Company with respect to such grantee, request additional information about the storage and processing of the Data with respect to such grantee, recommend any necessary corrections to the Data with respect to the grantee, or refuse or withdraw the consents herein in writing, in any case without cost, by contacting his or her local human resources representative. The Company may cancel the grantee’s eligibility to participate in the Plan, and in the Committee’s discretion, the grantee may forfeit any outstanding Awards if the grantee refuses or withdraws the consents described herein. For more information on the consequences of refusal to consent or withdrawal of consent, grantees may contact their local human resources representative.

SECTION 17. EFFECTIVE DATE OF PLAN

This Plan shall become effective upon approval by the holders of a majority of the votes cast at a meeting of shareholders at which a quorum is present. Subject to such approval by the shareholders and to the requirement that no Stock may be issued hereunder prior to such approval, Stock Options and other Awards may be granted hereunder on and after adoption of this Plan by the Board. No grants of Stock Options and other Awards may be made hereunder after July 23, 2028 and no grants of Incentive Stock Options may be made hereunder after the tenth (10th) anniversary of the date the Plan is approved by the Board.
