Any such allocation or delegation may be revoked by the Committee at any time. Without limiting the generality of the foregoing, the Committee may delegate to one or more officers of the Company or any Subsidiary the authority to act on behalf of the Committee with respect to any matter, right, obligation, or election which is the responsibility of or which is allocated to the Committee herein, and which may be so delegated as a matter of law, except for grants of Awards to persons (i) who are members of the Board or (ii) who are subject to Section 16 of the Exchange Act.

(d)Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or with respect to the Plan or any Award or any documents evidencing Awards granted pursuant to the Plan shall be within the sole discretion of the Committee, may be made at any time and shall be final, conclusive and binding upon all persons or entities, including, without limitation, the Company, any Affiliate, any Participant, any holder or beneficiary of any Award, and any stockholder of the Company.

(e)No member of the Board, the Committee or any employee or agent of the Company or any Subsidiary (each such person, an “Indemnifiable Person”) shall be liable for any action taken or omitted to be taken or any determination made with respect to the Plan or any Award hereunder (unless constituting fraud or a willful criminal act or omission). Each Indemnifiable Person shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense (including attorneys’ fees) that may be imposed upon or incurred by such Indemnifiable Person in connection with or resulting from any action, suit or proceeding to which such Indemnifiable Person may be a party or in which such Indemnifiable Person may be involved by reason of any action taken or omitted to be taken or determination made under the Plan or any Award agreement and against and from any and all amounts paid by such Indemnifiable Person with the Company’s approval, in settlement thereof, or paid by such Indemnifiable Person in satisfaction of any judgment in any such action, suit or proceeding against such Indemnifiable Person, and the Company shall advance to such Indemnifiable Person any such expenses promptly upon written request (which request shall include an undertaking by the Indemnifiable Person to repay the amount of such advance if it shall ultimately be determined as provided below that the Indemnifiable Person is not entitled to be indemnified); provided that the Company shall have the right, at its own expense, to assume and defend any such action, suit or proceeding and once the Company gives notice of its intent to assume the defense, the Company shall have sole control over such defense with counsel of the Company’s choice. The foregoing right of indemnification shall not be available to an Indemnifiable Person to the extent that a final judgment or other final adjudication (in either case not subject to further appeal) binding upon such Indemnifiable Person determines that the acts or omissions or determinations of such Indemnifiable Person giving rise to the indemnification claim resulted from such Indemnifiable Person’s fraud or willful criminal act or omission or that such right of indemnification is otherwise prohibited by law or by the Company’s or any Subsidiary’s organizational documents. The foregoing right of indemnification shall not be exclusive of or otherwise supersede any other rights of indemnification to which such Indemnifiable Persons may be entitled under the Company’s Certificate of Incorporation or Bylaws, as a matter of law, individual indemnification agreement or contract or otherwise, or any other power that the Company may have to indemnify such Indemnifiable Persons or hold them harmless.

(f)Notwithstanding anything to the contrary contained in the Plan, the Board may, in its sole discretion, at any time and from time to time, grant Awards and administer the Plan with respect to such Awards. Any such actions by the Board shall be subject to the applicable rules of the NYSE or any other securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted. In any such case, the Board shall have all the authority granted to the Committee under the Plan.

5.Grant of Awards; Shares Subject to the Plan; Limitations.

(a)The Committee may, from time to time, grant Awards to one or more Eligible Persons. All Awards granted under the Plan shall vest and become exercisable in such manner and on such date or dates or upon such event or events as determined by the Committee, including, without limitation, attainment of Performance Criteria, subject to the Minimum Vesting Condition.

(b)Awards granted under the Plan shall be subject to the following limitations: (i) subject to Section 11 of the Plan, no more than 17,500,000 shares of Common Stock (the “Absolute Share Limit”) shall be available for Awards under the Plan (excluding those shares of Restricted Stock received by Participants in exchange for (or redemption of) partnership or limited liability interests contemporaneous with the adoption of the Plan); (ii) subject to Section 11 of the Plan, no more than the number of shares of Common Stock equal to the Absolute Share Limit may be delivered in the aggregate pursuant to the exercise of Incentive Stock Options granted under the Plan; and (iii) the maximum number of shares of Common Stock subject to Awards granted during a single fiscal year to any Non-Employee Director, taken together with any cash fees paid to such Non-Employee Director during the fiscal year, shall not exceed $1,000,000 in total value (calculating the value of any such Awards based on the grant date fair value of such Awards for financial reporting purposes and excluding, for this purpose, the value of any dividend equivalent payments paid pursuant to any Award granted in a previous fiscal year).

(c)Other than with respect to Substitute Awards, to the extent that an Award expires or is canceled, forfeited or terminated, in whole or in part, (including, without limitation, for failure to achieve service vesting and/or performance vesting conditions) without issuance to the Participant of shares of Common Stock to which the Award related or cash or other property in lieu thereof, the unissued shares of Common Stock will again be available for grant under the Plan. The issuance of Shares or the payment of cash upon the exercise of an Award or in consideration of the cancellation or termination of an Award shall reduce the total number of Shares available under the Plan, as applicable. If Shares are not issued or are withheld from payment of an Award to satisfy tax obligations with respect to the Award, such Shares will not be added back to the aggregate number of Shares with respect to which Awards may be granted under the Plan, but rather will count against the aggregate number of Shares with respect to which Awards may be granted under the Plan. When an Option or Stock Appreciation Right is granted under the Plan, the number of Shares subject to the Option or Stock Appreciation Right will be counted against the aggregate number of Shares with respect to which Awards may be granted under the Plan as one Share for every Share subject to such Option or Stock Appreciation Right, regardless of the actual number of Shares (if any) used to settle such Option or Stock Appreciation Right upon exercise.

(d)Shares of Common Stock delivered by the Company in settlement of Awards may be authorized and unissued shares, shares held in the treasury of the Company, shares purchased on the open market or by private purchase or a combination of the foregoing.

(e)Awards may, in the sole discretion of the Committee, be granted under the Plan in assumption of, or in substitution for, outstanding awards previously granted by an entity directly or indirectly acquired by the Company or with which the Company combines (“Substitute Awards”). Substitute Awards shall not be counted against the Absolute Share Limit; provided, that Substitute Awards issued in connection with the assumption of, or in substitution for, outstanding options intended to qualify as “incentive stock options” within the meaning of Section 422 of the Code shall be counted against the aggregate number of shares of Common Stock available for Awards of Incentive Stock Options under the Plan. Subject to applicable stock exchange requirements, available shares under a stockholder approved plan of an entity directly or indirectly acquired by the Company or with which the Company combines (as appropriately adjusted to reflect the acquisition or combination transaction) may be used for Awards under the Plan and shall not reduce the number of shares of Common Stock available for delivery under the Plan.

6.Eligibility. Participation in the Plan shall be limited to Eligible Persons.

7.Options.

(a)General. Each Option granted under the Plan shall be evidenced by an Award agreement, in written or electronic form, which agreement need not be the same for each Participant. Each Option so granted shall be subject to the conditions set forth in this Section 7, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement. All Options granted under the Plan shall be Nonqualified Stock Options unless the applicable Award agreement expressly states that the Option is intended to be an Incentive Stock Option. Incentive Stock Options shall be granted only to Eligible Persons who are employees of the Company and its Affiliates, and no Incentive Stock Option shall be granted to any Eligible Person who is ineligible to receive an Incentive Stock Option under the Code. No Option shall be treated as an Incentive Stock Option unless the Plan has been approved by the stockholder of the Company in a manner intended to comply with the stockholder approval requirements of Section 422(b)(1) of the Code, provided that any Option intended to be an Incentive Stock Option shall not fail to be effective solely on account of a failure to obtain such approval, but rather such Option shall be treated as a Nonqualified Stock Option unless and until such approval is obtained. In the case of an Incentive Stock Option, the terms and conditions of such grant shall be subject to and comply with such rules as may be prescribed by Section 422 of the Code. If for any reason an Option intended to be an Incentive Stock Option (or any portion thereof) shall not qualify as an Incentive Stock Option, then, to the extent of such nonqualification, such Option or portion thereof shall be regarded as a Nonqualified Stock Option appropriately granted under the Plan.

(b)Exercise Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the exercise price (“Exercise Price”) per share of Common Stock for each Option shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant); provided, however, that in the case of an Incentive Stock Option granted to an employee who, at the time of the grant of such Option, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Affiliate, the Exercise Price per share shall be no less than 110% of the Fair Market Value per share on the Date of Grant.

(c)Vesting and Expiration; Termination.

(i)Options shall vest and become exercisable in such manner and on such date or dates or upon such events determined by the Committee and shall expire after such period, not to exceed 10 years, as may be determined by the Committee (the “Option Period”); provided, that if the Option Period (other than in the case of an Incentive Stock Option) would expire at a time when trading in the shares of Common Stock is prohibited by the Company’s insider trading policy (or Company-imposed “blackout period”), the Option Period shall be automatically extended until the 30th day following the expiration of such prohibition; provided, however, that in no event shall the Option Period exceed five years from the Date of Grant in the case of an Incentive Stock Option granted to a Participant who on the Date of Grant owns stock representing more than 10% of the voting power of all classes of stock of the Company or any Affiliate.

(ii)The terms and conditions with respect to the treatment of Options in the event of a Participant’s Termination shall be determined by the Committee and reflected in the applicable Award agreement.

(d)Method of Exercise and Form of Payment. No shares of Common Stock shall be delivered pursuant to any exercise of an Option until payment in full of the Exercise Price therefor is received by the Company and the Participant has paid to the Company an amount equal to any Federal,

state, local and non-U.S. income and employment and any other applicable taxes required to be withheld. Options which have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company (or telephonic instructions to the extent provided by the Committee) in accordance with the terms of the Option accompanied by payment of the Exercise Price. The Exercise Price shall be payable (i) in cash, check, cash equivalent and/or shares of Common Stock valued at the Fair Market Value at the time the Option is exercised (including, pursuant to procedures approved by the Committee, by means of attestation of ownership of a sufficient number of shares of Common Stock in lieu of actual delivery of such shares to the Company); provided, that such shares of Common Stock are not subject to any pledge or other security interest; or (ii) by such other method as the Committee may permit in its sole discretion, including without limitation: (A) in other property having a fair market value on the date of exercise equal to the Exercise Price or (B) if there is a public market for the shares of Common Stock at such time, by means of a broker-assisted “cashless exercise” pursuant to which the Company is delivered (including telephonically to the extent permitted by the Committee) a copy of irrevocable instructions to a stockbroker to sell the shares of Common Stock otherwise deliverable upon the exercise of the Option and to deliver promptly to the Company an amount equal to the Exercise Price or (C) a “net exercise” procedure effected by withholding the minimum number of shares of Common Stock otherwise deliverable in respect of an Option that are needed to pay the Exercise Price and all applicable required withholding and any other applicable taxes, except as otherwise provided in Section 13(d). Any fractional shares of Common Stock shall be settled in cash.

(e)Notification upon Disqualifying Disposition of an Incentive Stock Option. Each Participant awarded an Incentive Stock Option under the Plan shall notify the Company in writing immediately after the date he or she makes a disqualifying disposition of any Common Stock acquired pursuant to the exercise of such Incentive Stock Option. A disqualifying disposition is any disposition (including, without limitation, any sale) of such Common Stock before the later of (A) two years after the Date of Grant of the Incentive Stock Option or (B) one year after the date of exercise of the Incentive Stock Option. The Company may, if determined by the Committee and in accordance with procedures established by the Committee, retain possession, as agent for the applicable Participant, of any Common Stock acquired pursuant to the exercise of an Incentive Stock Option until the end of the period described in the preceding sentence, subject to complying with any instructions from such Participant as to the sale of such Common Stock.

(f)Compliance With Laws, etc. Notwithstanding the foregoing, in no event shall a Participant be permitted to exercise an Option in a manner which the Committee determines would violate the Sarbanes-Oxley Act of 2002, or any other applicable law or the applicable rules and regulations of the Securities and Exchange Commission or the applicable rules and regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or traded.

8.Stock Appreciation Rights.

(a)General. Each SAR granted under the Plan shall be evidenced by an Award agreement, in written or electronic form, which agreement need not be the same for each Participant. Each SAR so granted shall be subject to the conditions set forth in this Section 8, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement. Any Option granted under the Plan may include tandem SARs. The Committee also may award SARs to Eligible Persons independent of any Option.

(b)Strike Price. Except as otherwise provided by the Committee in the case of Substitute Awards, the strike price (“Strike Price”) per share of Common Stock for each SAR shall not be less than 100% of the Fair Market Value of such share (determined as of the Date of Grant). Notwithstanding the foregoing, a SAR granted in tandem with (or in substitution for) an Option previously granted shall have a Strike Price equal to the Exercise Price of the corresponding Option.

(c)Vesting and Expiration.

(i)A SAR granted in connection with an Option shall become exercisable and shall expire according to the same vesting schedule and expiration provisions as the corresponding Option. A SAR granted independent of an Option shall vest and become exercisable and shall expire in such manner and on such date or dates or upon such events determined by the Committee and shall expire after such period, not to exceed 10 years, as may be determined by the Committee (the “SAR Period”); provided, that if the SAR Period would expire at a time when trading in the shares of Common Stock is prohibited by the Company’s insider trading policy (or Company-imposed “blackout period”), the SAR Period shall be automatically extended until the 30th day following the expiration of such prohibition.

(ii)The terms and conditions with respect to the treatment of SARs in the event of a Participant’s Termination shall be determined by the Committee and reflected in the applicable Award agreement.

(d)Method of Exercise. SARs which have become exercisable may be exercised by delivery of written or electronic notice of exercise to the Company in accordance with the terms of the Award, specifying the number of SARs to be exercised and the date on which such SARs were awarded.

(e)Payment. Upon the exercise of a SAR, the Company shall pay to the Participant an amount equal to the number of shares subject to the SAR that are being exercised multiplied by the excess, if any, of the Fair Market Value of one share of Common Stock on the exercise date over the Strike Price, less an amount equal to any Federal, state, local and non-U.S. income, employment and any other applicable taxes required to be withheld. The Company shall pay such amount in cash, in shares of Common Stock valued at Fair Market Value, or any combination thereof, as determined by the Committee. Any fractional shares of Common Stock shall be settled in cash.

(f)Substitution of SARs for Nonqualified Stock Options. The Committee shall have the authority in its sole discretion to substitute, without the consent of the affected Participant or any holder or beneficiary of SARs, SARs settled in shares of Common Stock (or settled in shares or cash in the sole discretion of the Committee) for outstanding Nonqualified Stock Options, provided that (i) the substitution shall not otherwise result in a modification of the terms of any such Nonqualified Stock Option, (ii) the number of shares of Common Stock underlying the substituted SARs shall be the same as the number of shares of Common Stock underlying such Nonqualified Stock Options and (iii) the Strike Price of the substituted SARs shall be equal to the Exercise Price of such Nonqualified Stock Options; provided, however, that if, in the opinion of the Company’s independent public auditors, the foregoing provision creates adverse accounting consequences for the Company, such provision shall be considered null and void.

9.Restricted Stock and Restricted Stock Units.

(a)General. Each grant of Restricted Stock and Restricted Stock Units shall be evidenced by an Award agreement, in written or electronic form, which agreement need not be the same

for each Participant. Each Restricted Stock and Restricted Stock Unit so granted shall be subject to the conditions set forth in this Section 9, and to such other conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement.

(b)Stock Certificates and Book Entry; Escrow or Similar Arrangement. Upon the grant of Restricted Stock, the Committee shall cause a stock certificate registered in the name of the Participant to be issued or shall cause share(s) of Common Stock to be registered in the name of the Participant and held in book-entry form subject to the Company’s directions and, if the Committee determines that the Restricted Stock shall be held by the Company or in escrow rather than delivered to the Participant pending the release of the applicable restrictions, the Committee may require the Participant to additionally execute and deliver to the Company (i) an escrow agreement satisfactory to the Committee, if applicable, and (ii) the appropriate stock power (endorsed in blank) with respect to the Restricted Stock covered by such agreement. If a Participant shall fail to execute and deliver (in a manner permitted under Section 13(a) of the Plan or as otherwise determined by the Committee) an agreement evidencing an Award of Restricted Stock and, if applicable, an escrow agreement and blank stock power within the amount of time specified by the Committee, the Award shall be null and void. Subject to the restrictions set forth in this Section 9 and the applicable Award agreement, the Participant generally shall have the rights and privileges of a stockholder as to such Restricted Stock, including without limitation the right to vote such Restricted Stock and to receive any dividends payable on such shares of Restricted Stock. To the extent shares of Restricted Stock are forfeited, any stock certificates issued to the Participant evidencing such shares shall be returned to the Company, and all rights of the Participant to such shares and as a stockholder with respect thereto shall terminate without further obligation on the part of the Company.

(c)Vesting; Acceleration of Lapse of Restrictions.

(i)The Restricted Period with respect to Restricted Stock and Restricted Stock Units shall lapse in such manner and on such date or dates or upon such events determined by the Committee.

(ii)The terms and conditions with respect to the treatment of Restricted Stock and Restricted Stock Units in the event of a Participant’s Termination shall be determined by the Committee and reflected in the applicable Award agreement.

(d)Delivery of Restricted Stock and Settlement of Restricted Stock Units.

(i)Upon the expiration of the Restricted Period with respect to any shares of Restricted Stock, the restrictions set forth in the applicable Award agreement shall be of no further force or effect with respect to such shares, except as set forth in the applicable Award agreement. If an escrow arrangement is used, upon such expiration, the Company shall deliver to the Participant, or his or her beneficiary, without charge, the stock certificate (or, if applicable, a notice evidencing a book entry notation) evidencing the shares of Restricted Stock which have not then been forfeited and with respect to which the Restricted Period has expired (rounded down to the nearest full share).

(ii)Unless otherwise provided by the Committee in an Award agreement or otherwise, upon the expiration of the Restricted Period with respect to any outstanding Restricted Stock Units, the Company shall deliver to the Participant, or his or her beneficiary, without charge, one share of Common Stock (or other securities or other property, as applicable) for each

such outstanding Restricted Stock Unit granted pursuant to the applicable Award Agreement; provided, however, that the Committee may, in its sole discretion, elect to (i) pay cash or part cash and part Common Stock in lieu of delivering only shares of Common Stock in respect of such Restricted Stock Units or (ii) defer the delivery of Common Stock (or cash or part Common Stock and part cash, as the case may be) beyond the expiration of the Restricted Period if such extension would not cause adverse tax consequences under Section 409A of the Code. If a cash payment is made in lieu of delivering shares of Common Stock, the amount of such payment shall be equal to the Fair Market Value of the Common Stock as of the date on which the Restricted Period lapsed with respect to such Restricted Stock Units. To the extent provided in an Award agreement, the holder of outstanding Restricted Stock Units shall be entitled to be credited with dividend equivalent payments (upon the payment by the Company of dividends on shares of Common Stock) either in cash or, at the sole discretion of the Committee, in shares of Common Stock having a Fair Market Value equal to the amount of such dividends (and interest may, at the sole discretion of the Committee, be credited on the amount of cash dividend equivalents at a rate and subject to such terms as determined by the Committee), which accumulated dividend equivalents (and interest thereon, if applicable) shall be payable at the same time as the underlying Restricted Stock Units are settled following the release of restrictions on such Restricted Stock Units, and, if such Restricted Stock Units are forfeited, the Participant shall have no right to such dividend equivalent payments.

(e)Legends on Restricted Stock. Each certificate representing Restricted Stock awarded under the Plan, if any, shall bear a legend substantially in the form of the following, in addition to any other information the Company deems appropriate, until the lapse of all restrictions with respect to such shares of Common Stock:

TRANSFER OF THIS CERTIFICATE AND THE SHARES REPRESENTED HEREBY IS RESTRICTED PURSUANT TO THE TERMS OF THE AMENDED AND RESTATED SUMMIT MATERIALS, INC. 2015 OMNIBUS INCENTIVE PLAN AND A RESTRICTED STOCK AWARD AGREEMENT, BETWEEN SUMMIT MATERIALS, INC. AND PARTICIPANT. A COPY OF SUCH PLAN AND AWARD AGREEMENT IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF SUMMIT MATERIALS, INC.

10.Other Stock-Based Awards and Other Cash-Based Awards.

(a)The Committee may issue unrestricted Common Stock, rights to receive grants of Awards at a future date, other Awards denominated in Common Stock (including, without limitation, performance shares or performance units, or other Awards denominated in cash (including cash bonuses)), under the Plan to Eligible Persons, alone or in tandem with other Awards, in such amounts as the Committee shall from time to time in its sole discretion determine. Each Other Stock-Based Award or Other Cash-Based Award, as applicable, granted under the Plan shall be evidenced by an Award agreement, in written or electronic form, which agreement need not be the same for each Participant, or as otherwise determined by the Committee. Each Other Stock-Based Award or Cash-Based Award, as applicable, so granted shall be subject to such conditions not inconsistent with the Plan as may be reflected in the applicable Award agreement.

(b)The terms and conditions with respect to the treatment of Other Stock-Based Awards in the event of a Participant’s Termination shall be determined by the Committee and reflected in the applicable Award agreement.

11.Changes in Capital Structure and Similar Events. In the event of (a) any dividend (other than regular cash dividends) or other distribution (whether in the form of cash, shares of Common Stock, other securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, split-off, spin-off, combination, repurchase or exchange of shares of Common Stock or other securities of the Company, issuance of warrants or other rights to acquire shares of Common Stock or other securities of the Company, or other similar corporate transaction or event (including, without limitation, a Change in Control) that affects the shares of Common Stock, or (b) unusual or nonrecurring events (including, without limitation, a Change in Control) affecting the Company, any Affiliate, or the financial statements of the Company or any Affiliate, or changes in applicable rules, rulings, regulations or other requirements of any governmental body or securities exchange or inter-dealer quotation system, accounting principles or law, such that in either case an adjustment is determined by the Committee in its sole discretion to be necessary or appropriate, then the Committee shall make any such adjustments in such manner as it may deem equitable, including without limitation, any or all of the following:

(i)adjusting any or all of (A) the Absolute Share Limit, or any other limit applicable under the Plan with respect to the number of Awards which may be granted hereunder, (B) the number of shares of Common Stock or other securities of the Company (or number and kind of other securities or other property) which may be delivered in respect of Awards or with respect to which Awards may be granted under the Plan (including, without limitation, adjusting any or all of the limitations under Section 5 of the Plan) and (C) the terms of any outstanding Award, including, without limitation, (1) the number of shares of Common Stock or other securities of the Company (or number and kind of other securities or other property) subject to outstanding Awards or to which outstanding Awards relate, (2) the Exercise Price or Strike Price with respect to any Award or (3) any applicable performance measures (including, without limitation, Performance Criteria);

(ii)providing for a substitution or assumption of Awards (or awards of an acquiring company), accelerating the exercisability of, lapse of restrictions on, or termination of, Awards or providing for a period of time (which shall not be required to be more than 10 days) for Participants to exercise outstanding Awards prior to the occurrence of such event (and any such Award not so exercised shall terminate upon the occurrence of such event); and

(iii)cancelling any one or more outstanding Awards and causing to be paid to the holders holding vested Awards (including any Awards that would vest as a result of the occurrence of such event but for such cancellation) the value of such Awards, if any, as determined by the Committee (which if applicable may be based upon the price per share of Common Stock received or to be received by other stockholders of the Company in such event), including without limitation, in the case of an outstanding Option or SAR, a cash payment in an amount equal to the excess, if any, of the Fair Market Value (as of a date specified by the Committee) of the shares of Common Stock subject to such Option or SAR over the aggregate Exercise Price or Strike Price of such Option or SAR, respectively (it being understood that, in such event, any Option or SAR having a per share Exercise Price or Strike Price equal to, or in excess of, the Fair Market Value of a share of Common Stock subject thereto may be canceled and terminated without any payment or consideration therefor);

provided, however, that in the case of any “equity restructuring” (within the meaning of the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor pronouncement thereto)), the Committee shall make an equitable or proportionate adjustment to

outstanding Awards to reflect such equity restructuring. Any adjustment in Incentive Stock Options under this Section 11 (other than any cancellation of Incentive Stock Options) shall be made only to the extent not constituting a “modification” within the meaning of Section 424(h)(3) of the Code, and any adjustments under this Section 11 shall be made in a manner which does not adversely affect the exemption provided pursuant to Rule 16b-3 under the Exchange Act. Any such adjustment shall be conclusive and binding for all purposes. Payments to holders pursuant to clause (iii) above shall be made in cash or, in the sole discretion of the Committee, in the form of such other consideration necessary for a Participant to receive property, cash, or securities (or combination thereof) as such Participant would have been entitled to receive upon the occurrence of the transaction if the Participant had been, immediately prior to such transaction, the holder of the number of shares of Common Stock covered by the Award at such time (less any applicable Exercise Price or Strike Price). In addition, prior to any payment or adjustment contemplated under this Section 11, the Committee may require a Participant to (A) represent and warrant as to the unencumbered title to his Awards, (B) bear such Participant’s pro rata share of any post-closing indemnity obligations, and be subject to the same post-closing purchase price adjustments, escrow terms, offset rights, holdback terms, and similar conditions as the other holders of Stock, (C) deliver customary transfer documentation as reasonably determined by the Committee and (D) satisfy any applicable tax withholding obligations.

12.Amendments and Termination.

(a)Amendment and Termination of the Plan. The Board may amend, alter, suspend, discontinue, or terminate the Plan or any portion thereof at any time; provided, that no such amendment, alteration, suspension, discontinuation or termination shall be made without stockholder approval if (i) such approval is necessary to comply with any regulatory requirement applicable to the Plan (including, without limitation, as necessary to comply with any rules or regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company may be listed or quoted or for changes in GAAP to new accounting standards), (ii) it would materially increase the number of securities which may be issued under the Plan (except for increases pursuant to Section 5 or 11), or (iii) it would materially modify the requirements for participation in the Plan; provided, further, that any such amendment, alteration, suspension, discontinuance or termination that would materially and adversely affect the rights of any Participant or any holder or beneficiary of any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant, holder or beneficiary. Notwithstanding the foregoing, no amendment shall be made to the last proviso of Section 12(b) without stockholder approval.

(b)Amendment of Award Agreements. The Committee may, to the extent consistent with the terms of any applicable Award agreement, waive any conditions or rights under, amend any terms of, or alter, suspend, discontinue, cancel or terminate, any Award theretofore granted or the associated Award agreement, prospectively or retroactively (including after a Participant’s Termination from the Company); provided that any such waiver, amendment, alteration, suspension, discontinuance, cancellation or termination that would materially and adversely affect the rights of any Participant with respect to any Award theretofore granted shall not to that extent be effective without the consent of the affected Participant; provided, further, that without stockholder approval, except as otherwise permitted under Section 11 of the Plan, (i) no amendment or modification may reduce the Exercise Price of any Option or the Strike Price of any SAR, (ii) the Committee may not cancel any outstanding Option or SAR and replace it with a new Option or SAR (with a lower Exercise Price or Strike Price, as the case may be) or other Award or cash payment that is greater than the value of the cancelled Option or SAR, and (iii) the Committee may not take any other action which is considered a “repricing” for purposes of the

stockholder approval rules of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted.

13.General.

(a)Award Agreements. Each Award under the Plan shall be evidenced by an Award agreement, which shall be delivered to the Participant and shall specify the terms and conditions of the Award and any rules applicable thereto, including without limitation, the effect on such Award of the death, Disability or Termination of a Participant, or of such other events as may be determined by the Committee. For purposes of the Plan, an Award agreement may be in any such form (written or electronic) as determined by the Committee (including, without limitation, a Board or Committee resolution, an employment agreement, a notice, a certificate or a letter) evidencing the Award. The Committee need not require an Award agreement to be signed by the Participant or a duly authorized representative of the Company.

(b)Nontransferability. Each Award shall be exercisable only by a Participant during the Participant’s lifetime, or, if permissible under applicable law, by the Participant’s legal guardian or representative. No Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant (including, without limitation, except as may be prohibited by applicable law, pursuant to a domestic relations order) other than by will or by the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or an Affiliate; provided that the designation of a beneficiary shall not constitute an assignment, alienation, pledge, attachment, sale, transfer or encumbrance.

(i)Notwithstanding the foregoing, the Committee may, in its sole discretion, permit Awards (other than Incentive Stock Options) to be transferred by a Participant, without consideration, subject to such rules as the Committee may adopt consistent with any applicable Award agreement to preserve the purposes of the Plan, to: (A) any person who is a “family member” of the Participant, as such term is used in the instructions to Form S-8 under the Securities Act or any successor form of registration statement promulgated by the Securities and Exchange Commission (collectively, the “Immediate Family Members”); (B) a trust solely for the benefit of the Participant and his or her Immediate Family Members; (C) a partnership or limited liability company whose only partners or stockholders are the Participant and his or her Immediate Family Members; or (D) a beneficiary to whom donations are eligible to be treated as “charitable contributions” for federal income tax purposes;

(each transferee described in clauses (A), (B), (C) and (D) above is hereinafter referred to as a “Permitted Transferee”); provided that the Participant gives the Committee advance written notice describing the terms and conditions of the proposed transfer and the Committee notifies the Participant in writing that such a transfer would comply with the requirements of the Plan.

(ii)The terms of any Award transferred in accordance with the immediately preceding sentence shall apply to the Permitted Transferee and any reference in the Plan, or in any applicable Award agreement, to a Participant shall be deemed to refer to the Permitted Transferee, except that (A) Permitted Transferees shall not be entitled to transfer any Award, other than by will or the laws of descent and distribution; (B) Permitted Transferees shall not be entitled to exercise any transferred Option unless there shall be in effect a registration statement on an appropriate form covering the shares of Common Stock to be acquired pursuant to the

exercise of such Option if the Committee determines, consistent with any applicable Award agreement, that such a registration statement is necessary or appropriate; (C) the Committee or the Company shall not be required to provide any notice to a Permitted Transferee, whether or not such notice is or would otherwise have been required to be given to the Participant under the Plan or otherwise; and (D) the consequences of the Termination of the Participant from the Company or an Affiliate under the terms of the Plan and the applicable Award agreement shall continue to be applied with respect to the Participant, including, without limitation, that an Option shall be exercisable by the Permitted Transferee only to the extent, and for the periods, specified in the Plan and the applicable Award agreement.

(c)Dividends and Dividend Equivalents. The Committee in its sole discretion may provide a Participant as part of an Award with dividends or dividend equivalents, payable in cash, shares of Common Stock, other securities, other Awards or other property, on a current or deferred basis, on such terms and conditions as may be determined by the Committee in its sole discretion, including without limitation, payment directly to the Participant, withholding of such amounts by the Company subject to vesting of the Award or reinvestment in additional shares of Common Stock, Restricted Stock or other Awards; provided, that no dividends or dividend equivalents shall be payable in respect of outstanding (i) Options or SARs or (ii) unearned Awards subject to performance conditions (other than or in addition to the passage of time and other than Awards structured as Restricted Stock) (although dividends and dividend equivalents may be accumulated in respect of unearned Awards and paid within 15 days after such Awards are earned and become payable or distributable).

(d)Tax Withholding.

(i)A Participant shall be required to pay to the Company or any Affiliate, and the Company or any Affiliate shall have the right and is hereby authorized to withhold, from any cash, shares of Common Stock, other securities or other property deliverable under any Award or from any compensation or other amounts owing to a Participant, the amount (in cash, Common Stock, other securities or other property) of any required withholding or any other applicable taxes in respect of an Award, its exercise, or any payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the Committee or the Company to satisfy all obligations for the payment of such withholding or any other applicable taxes.

(ii)Without limiting the generality of clause (i) above, the Committee may, in its sole discretion, permit a Participant to satisfy, in whole or in part, the foregoing withholding liability by (A) the delivery of shares of Common Stock (which are not subject to any pledge or other security interest) owned by the Participant having a Fair Market Value equal to such withholding liability or (B) having the Company withhold from the number of shares of Common Stock otherwise issuable or deliverable pursuant to the exercise or settlement of the Award a number of shares with a Fair Market Value equal to such withholding liability, provided that with respect to shares withheld pursuant to clause (B), the number of such shares may not have a Fair Market Value greater than the minimum required statutory withholding liability, unless the Committee, in its sole discretion, pursuant to an Award agreement or otherwise, expressly determines to allow Participants to satisfy, in whole or in part, any additional applicable withholding taxes payable by them with respect to an Award by having the Company withhold from the shares of Common Stock otherwise issuable or deliverable to, or that would otherwise be retained by, a Participant upon the grant, exercise, vesting or settlement of the Award, as applicable, shares of Common Stock having an aggregate Fair Market Value that is greater than

the applicable minimum required statutory withholding liability (but such withholding may in no event be in excess of the maximum statutory withholding amount(s) in a Participant’s relevant tax jurisdictions).

(e)No Claim to Awards; No Rights to Continued Employment; Waiver. No employee of the Company or an Affiliate, or other person, shall have any claim or right to be granted an Award under the Plan or, having been selected for the grant of an Award, to be selected for a grant of any other Award. There is no obligation for uniformity of treatment of Participants or holders or beneficiaries of Awards. The terms and conditions of Awards and the Committee’s determinations and interpretations with respect thereto need not be the same with respect to each Participant and may be made selectively among Participants, whether or not such Participants are similarly situated. Neither the Plan nor any action taken hereunder shall be construed as giving any Participant any right to be retained in the employ or service of the Company or an Affiliate, nor shall it be construed as giving any Participant any rights to continued service on the Board. The Company or any of its Affiliates may at any time dismiss a Participant from employment or discontinue any consulting relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan or any Award agreement. By accepting an Award under the Plan, a Participant shall thereby be deemed to have waived any claim to continued exercise or vesting of an Award or to damages or severance entitlement related to non-continuation of the Award beyond the period provided under the Plan or any Award agreement, except to the extent of any provision to the contrary in any written employment contract or other agreement between the Company and its Affiliates and the Participant, whether any such agreement is executed before, on or after the Date of Grant.

(f)International Participants. With respect to Participants who reside or work outside of the United States of America, the Committee may in its sole discretion amend the terms of the Plan or Sub-Plans or outstanding Awards with respect to such Participants in order to conform such terms with the requirements of local law or to obtain more favorable tax or other treatment for a Participant, the Company or its Affiliates.

(g)Designation and Change of Beneficiary. Each Participant may file with the Committee a written designation of one or more persons as the beneficiary(ies) who shall be entitled to receive the amounts payable with respect to an Award, if any, due under the Plan upon his or her death. A Participant may, from time to time, revoke or change his or her beneficiary designation without the consent of any prior beneficiary by filing a new designation with the Committee. The last such designation received by the Committee shall be controlling; provided, however, that no designation, or change or revocation thereof, shall be effective unless received by the Committee prior to the Participant’s death, and in no event shall it be effective as of a date prior to such receipt. If no beneficiary designation is filed by a Participant, the beneficiary shall be deemed to be his or her spouse or, if the Participant is unmarried at the time of death, his or her estate.

(h)Termination. Except as otherwise provided in an Award agreement, unless determined otherwise by the Committee at any point following such event: (i) neither a temporary absence from employment or service due to illness, vacation or leave of absence (including, without limitation, a call to active duty for military service through a Reserve or National Guard unit) nor a transfer from employment or service with one Service Recipient to employment or service with another Service Recipient (or vice-versa) shall be considered a Termination; and (ii) if a Participant undergoes a Termination of employment, but such Participant continues to provide services to the Company and its Affiliates in a non-employee capacity, such change in status shall not be considered a Termination for purposes of the Plan. Further, unless otherwise determined by the Committee, in the event that any

Service Recipient ceases to be an Affiliate of the Company (by reason of sale, divestiture, spin-off, or other similar transaction), unless a Participant’s employment or service is transferred to another entity that would constitute a Service Recipient immediately following such transaction, such Participant shall be deemed to have suffered a Termination hereunder as of the date of the consummation of such transaction.

(i)No Rights as a Stockholder. Except as otherwise specifically provided in the Plan or any Award agreement, no person shall be entitled to the privileges of ownership in respect of shares of Common Stock which are subject to Awards hereunder until such shares have been issued or delivered to that person.

(j)Government and Other Regulations.

(i)The obligation of the Company to settle Awards in shares of Common Stock or other consideration shall be subject to all applicable laws, rules, and regulations, and to such approvals by governmental agencies as may be required. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any shares of Common Stock pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel (if the Company has requested such an opinion), satisfactory to the Company, that such shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the shares of Common Stock to be offered or sold under the Plan. The Committee shall have the authority to provide that all shares of Common Stock or other securities of the Company or any Affiliate delivered under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award agreement, the Federal securities laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter- dealer quotation system on which the securities of the Company are listed or quoted and any other applicable Federal, state, local or non-U.S. laws, rules, regulations and other requirements, and, without limiting the generality of Section 9 of the Plan, the Committee may cause a legend or legends to be put on certificates representing shares of Common Stock or other securities of the Company or any Affiliate delivered under the Plan to make appropriate reference to such restrictions or may cause such Common Stock or other securities of the Company or any Affiliate delivered under the Plan in book-entry form to be held subject to the Company’s instructions or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that it in its sole discretion deems necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject.

(ii)The Committee may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of shares of Common Stock from the public markets, the Company’s issuance of Common Stock to the Participant, the Participant’s acquisition of Common Stock from the Company and/or the Participant’s sale of Common Stock to the public markets, illegal, impracticable or inadvisable. If the Committee determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall pay to the

Participant an amount equal to the excess of (A) the aggregate Fair Market Value of the shares of Common Stock subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the shares would have been vested or delivered, as applicable), over (B) the aggregate Exercise Price or Strike Price (in the case of an Option or SAR, respectively) or any amount payable as a condition of delivery of shares of Common Stock (in the case of any other Award). Such amount shall be delivered to the Participant as soon as practicable following the cancellation of such Award or portion thereof.

(k)No Section 83(b) Elections Without Consent of Company. No election under Section 83(b) of the Code or under a similar provision of law may be made unless expressly permitted by the terms of the applicable Award agreement or by action of the Committee in writing prior to the making of such election. If a Participant, in connection with the acquisition of shares of Common Stock under the Plan or otherwise, is expressly permitted to make such election and the Participant makes the election, the Participant shall notify the Company of such election within ten days of filing notice of the election with the Internal Revenue Service or other governmental authority, in addition to any filing and notification required pursuant to Section 83(b) of the Code or other applicable provision.

(l)Payments to Persons Other Than Participants. If the Committee shall find that any person to whom any amount is payable under the Plan is unable to care for his or her affairs because of illness or accident, or is a minor, or has died, then any payment due to such person or his or her estate (unless a prior claim therefor has been made by a duly appointed legal representative) may, if the Committee so directs the Company, be paid to his or her spouse, child, relative, an institution maintaining or having custody of such person, or any other person deemed by the Committee to be a proper recipient on behalf of such person otherwise entitled to payment. Any such payment shall be a complete discharge of the liability of the Committee and the Company therefor.

(m)Nonexclusivity of the Plan. Neither the adoption of this Plan by the Board nor the submission of this Plan to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under this Plan, and such arrangements may be either applicable generally or only in specific cases.

(n)No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate, on the one hand, and a Participant or other person or entity, on the other hand. No provision of the Plan or any Award shall require the Company, for the purpose of satisfying any obligations under the Plan, to purchase assets or place any assets in a trust or other entity to which contributions are made or otherwise to segregate any assets, nor shall the Company maintain separate bank accounts, books, records or other evidence of the existence of a segregated or separately maintained or administered fund for such purposes. Participants shall have no rights under the Plan other than as unsecured general creditors of the Company, except that insofar as they may have become entitled to payment of additional compensation by performance of services, they shall have the same rights as other employees under general law.

(o)Reliance on Reports. Each member of the Committee and each member of the Board shall be fully justified in acting or failing to act, as the case may be, and shall not be liable for having so acted or failed to act in good faith, in reliance upon any report made by the independent public accountant of the Company and its Affiliates and/or any other information furnished in connection with the Plan by any agent of the Company or the Committee or the Board, other than himself.

(p)Relationship to Other Benefits. No payment under the Plan shall be taken into account in determining any benefits under any pension, retirement, profit sharing, group insurance or other benefit plan of the Company except as otherwise specifically provided in such other plan or as required by applicable law.

(q)Governing Law. The Plan shall be governed by and construed in accordance with the internal laws of the State of Delaware (or, if the Company or its successor hereunder ceases to be organized in Delaware, then the internal laws of the state or other jurisdiction of incorporation) applicable to contracts made and performed wholly within the State of Delaware (or such other jurisdiction described above), without giving effect to the conflict of laws provisions thereof.

(r)Severability. If any provision of the Plan or any Award or Award agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as to any person or entity or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable laws, or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be construed or deemed stricken as to such jurisdiction, person or entity or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

(s)Obligations Binding on Successors. The obligations of the Company under the Plan shall be binding upon any successor corporation or organization resulting from the merger, consolidation or other reorganization of the Company, or upon any successor corporation or organization succeeding to substantially all of the assets and business of the Company.

(t)409A of the Code.

(i)Notwithstanding any provision of the Plan to the contrary, it is intended that the provisions of this Plan comply with Section 409A of the Code, and all provisions of this Plan shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes or penalties under Section 409A of the Code. Each Participant is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on or in respect of such Participant in connection with this Plan or any other plan maintained by the Company (including any taxes and penalties under Section 409A of the Code), and neither the Company nor any Affiliate shall have any obligation to indemnify or otherwise hold such Participant (or any beneficiary) harmless from any or all of such taxes or penalties. With respect to any Award that is considered “deferred compensation” subject to Section 409A of the Code, references in the Plan to “termination of employment” (and substantially similar phrases) shall mean “separation from service” within the meaning of Section 409A of the Code. For purposes of Section 409A of the Code, each of the payments that may be made in respect of any Award granted under the Plan is designated as separate payments.

(ii)Notwithstanding anything in the Plan to the contrary, if a Participant is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, no payments in respect of any Awards that are “deferred compensation” subject to Section 409A of the Code and which would otherwise be payable upon the Participant’s “separation from service” (as defined in Section 409A of the Code) shall be made to such Participant prior to the date that is six months after the date of such Participant’s “separation from service” or, if earlier, the Participant’s date of death. Following any applicable six month delay, all such delayed payments

will be paid in a single lump sum on the earliest date permitted under Section 409A of the Code that is also a business day.

(iii)Unless otherwise provided by the Committee in an Award agreement or otherwise, in the event that the timing of payments in respect of any Award (that would otherwise be considered “deferred compensation” subject to Section 409A of the Code) would be accelerated upon the occurrence of (A) a Change in Control, no such acceleration shall be permitted unless the event giving rise to the Change in Control satisfies the definition of a change in the ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation pursuant to Section 409A of the Code and any Treasury Regulations promulgated thereunder or (B) a Disability, no such acceleration shall be permitted unless the Disability also satisfies the definition of “Disability” pursuant to Section 409A of the Code and any Treasury Regulations promulgated thereunder.

(u)Clawback/Forfeiture. Notwithstanding anything to the contrary contained herein, an Award agreement may provide that the Committee may in its sole discretion cancel such Award if the Participant, without the consent of the Company, while employed by or providing services to the Company or any Affiliate or after Termination, violates a non-competition, non-solicitation or non-disclosure covenant or agreement or otherwise has engaged in or engages in other Detrimental Activity that is in conflict with or adverse to the interests of any Affiliate, including fraud or conduct contributing to any financial restatements or irregularities, as determined by the Committee in its sole discretion. The Committee may also provide in an Award agreement that if the Participant otherwise has engaged in or engages in any activity referred to in the preceding sentence, the Participant will forfeit any gain realized on the vesting or exercise of such Award, and must repay the gain to the Company. The Committee may also provide in an Award agreement that if the Participant receives any amount in excess of what the Participant should have received under the terms of the Award for any reason (including without limitation by reason of a financial restatement, mistake in calculations or other administrative error), then the Participant shall be required to repay any such excess amount to the Company. Without limiting the foregoing, all Awards shall be subject to reduction, cancellation, forfeiture or recoupment to the extent necessary to comply with applicable law.

(v)Expenses; Gender; Titles and Headings. The expenses of administering the Plan shall be borne by the Company and its Affiliates. Masculine pronouns and other words of masculine gender shall refer to both men and women. The titles and headings of the sections in the Plan are for convenience of reference only, and in the event of any conflict, the text of the Plan, rather than such titles or headings shall control.
