5.3    Adjustments in Awards and Authorized Shares. In the event of a stock dividend or stock split, the number of Shares subject to outstanding Awards and the numerical limits set forth in Section 5.1 shall automatically be adjusted to prevent the dilution or diminution of such Awards, except to the extent directed otherwise by the Committee, and in the event of such an adjustment to an Option or Stock Appreciation Right, the exercise price thereof shall be correspondingly adjusted in the manner prescribed by sections 422 or 409A of the Code, as applicable, so as not to result in loss of the intended tax status of the Award. In the event of a merger, reorganization, consolidation, recapitalization, separation, liquidation, combination, or other similar change in the corporate structure of the Company affecting the Shares, the Committee shall adjust the number and class of Shares which may be delivered under the Plan, the number, class and price of Shares subject to outstanding Awards, and the

numerical limits set forth in Section 5.1, in such manner as the Committee shall determine to be advisable or appropriate to prevent the dilution or diminution of such Awards. The Committee is authorized to make adjustments to the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events affecting the Company, or in response to changes in applicable laws, regulations, or accounting principles. The determination of the Committee as to the foregoing adjustments, if any, shall be conclusive and binding on all Participants.

5.6    Restrictions on Share Transferability. Except as provided in Section 12.6 or as may be allowed by the Committee or provided under an Award Agreement, no Award may be transferred, gifted, bequeathed, pledged, assigned, or otherwise alienated or hypothecated, voluntarily or involuntarily. The Committee may impose such restrictions on any Award of Shares or Shares acquired pursuant to the exercise of an Award as it may deem advisable or appropriate, including, but not limited to, restrictions related to applicable Federal securities laws, the requirements of any national securities exchange or system upon which Shares are then listed or traded, and any blue sky or state securities laws.

5.7    Minimum Vesting. Except for Awards with a value of less than $25,000 at the Grant Date, no more than 25% of an Award may be vested prior to the first anniversary of the Grant Date; provided, that an Award may become fully vested prior to the first anniversary of the Grant Date in the event of a Termination of Service due to death, Disability or Retirement.

Notwithstanding any other provisions in this Plan or an Award Agreement, the Committee may cancel any Award to a Participant, require reimbursement of any such Award by a Participant, and effect any other right of recoupment of equity or other compensation provided under the Plan in accordance with any recoupment or clawback policies adopted by the Company to comply with applicable law, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act and the requirements of any national securities exchange or system upon which Shares are then listed or traded, or to comport with good corporate governance practices, as such policies may be amended from time to time. By accepting an Award under this Plan, each Participant agrees to be bound by the recoupment or clawback policy, as in effect or as may be adopted or modified from time to time by the Company in its discretion. No recovery of compensation under such a recoupment or clawback policy will be an event giving rise to a right to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company or any of its subsidiaries or affiliates.

6.1    Grant of Options. Subject to the terms and provisions of the Plan, Options may be granted to Participants at any time and from time to time as determined by the Committee.

6.3.3 Substitute Options. Notwithstanding the provisions of Sections 6.3.1 and 6.3.2, in the event that the Company consummates a transaction described in section 424(a) of the Code, persons who become Participants on account of such transaction may be granted Options in substitution for options granted by such former employer or recipient of services. If such substitute Options are granted, the Committee, consistent with section 424(a) and 409A of the Code, may determine that such substitute Options shall have an exercise price less than one hundred percent (100%) of the Fair Market Value of the Shares on the Grant Date in order to provide in-the-money value at the Grant Date equal to the in‑the-money value of the substituted Options in accordance with section 424(a) and 409A of the Code.

6.6.    Payment. Options shall be exercised by a Participant's delivery of a notice of exercise to the Secretary of the Company (or its designee), setting forth the number of Shares with respect to which the Option is to be exercised, accompanied by full payment for the Shares.

Upon the exercise of an Option, the Exercise Price shall be payable to the Company in full in cash or its equivalent. The Committee may also permit exercise (a) by tendering previously acquired Shares having an aggregate Fair Market Value at the time of exercise equal to the total Exercise Price, or (b) by any other means which the Committee determines to provide legal consideration for the Shares, and to be consistent with the purposes of the Plan.

As soon as practicable after receipt of a notification of exercise and full payment for the Shares purchased, the Company shall deliver to the Participant, Share certificates (which may be in book entry form) representing such Shares. Until the issuance of the stock certificates, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Shares as to which the Option has been exercised. No adjustment will be made for a dividend or other rights for which a record date is established prior to the date the certificates are issued.

The Committee may set performance objectives based upon (a) the achievement of Company-wide, divisional or individual goals, (b) applicable Federal or state securities laws, or (c) any other basis determined by the Committee in its discretion.

9.4    Earning of Performance Units/Shares. Subject to the terms of this Plan, after the applicable Performance Period has ended, the holder of Performance Units/Shares shall be entitled to receive payout on the number and value of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance goals or Performance Measures have been achieved.

9.5    Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares shall be as determined by the Committee and as evidenced in the Award Agreement. Subject to the terms of the Plan the Committee, in its sole discretion, may pay earned Performance Units/Shares in the form of cash or in Shares (or in a combination thereof) equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period. Any Shares may be granted subject to any restrictions deemed appropriate by the Committee. The determination of the Committee with respect to the form of payout of such Awards shall be set forth in the Award Agreement pertaining to the grant of the Award. Awards shall be paid no later than the last date permitted in order for the payment to be exempted from the definition of deferred compensation under section 409A of the Code.

9.6    Dividends and Other Distributions. At the discretion of the Committee, Participants holding Performance Units or Performance Shares may be entitled to receive dividend equivalents with respect to dividends declared with respect to the Shares. Such dividends shall be subject to the same accrual, forfeiture, and payout restrictions as apply to the Performance Units or Performance Shares to which such dividends equivalents relate.

9.7    Termination of Employment/Service Relationship. In the event of a Participant's Termination of Service, all Performance Units/Shares shall be forfeited by the Participant unless determined otherwise by the Committee, as set forth in the Participant's Award Agreement. Any such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Performance Units/Shares issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination.

10.1    Stock-Based Awards. The Committee may grant other types of equity-based or equity-related Awards (including the grant or offer for sale of unrestricted Shares) not distributed pursuant to Sections 6, 7, 8 or 9 (“Stock-Based Awards”) in such amounts and subject to such terms and conditions, as the Committee shall determine. The Committee shall have complete discretion in determining the amount of Stock-Based Awards granted to any Participant; provided, however, that during any Fiscal Year, no Participant shall receive Stock-Based Awards that are based on more than 50,000 Shares or on the initial value of 50,000 Shares.

10.2    Performance Objectives and Other Terms. The Committee may set performance objectives in its sole discretion which, depending on the extent to which they are met, will determine the number or value of Stock-Based Awards that will be paid out to the Participants. Any Performance Periods of Awards granted to Section 16 Persons shall, in all cases, exceed six (6) months in length (or such shorter period as may be permissible while maintaining compliance with Rule 16b-3). Each Award of Stock-Based Awards shall be evidenced by an Award Agreement that shall specify the Performance Period, and such other terms and conditions as the Committee, in its sole discretion,

shall determine. The Committee may set performance objectives based upon (a) the achievement of Company-wide, divisional or individual goals, (b) applicable Federal or state securities laws, or (c) any other basis determined by the Committee in its discretion.

10.3    Earning of Stock-Based Awards. Subject to the terms of this Plan, the holder of Stock-Based Awards shall be entitled to receive payout on the number and value of Stock-Based Awards earned by the Participant, to be determined as a function of the extent to which the corresponding performance goals have been achieved.

10.4    Payment of Awards. Payment of earned Stock-Based Awards shall be as determined by the Committee and as evidenced in the Award Agreement. Subject to the terms of the Plan, the Committee, shall pay earned Stock-Based Awards in Shares. Such Shares may be granted subject to any restrictions deemed appropriate by the Committee. Awards shall be paid no later than the last date permitted in order for the payment to be exempted from the definition of deferred compensation under section 409A of the Code.

10.5    Termination of Employment/Service Relationship. In the event of a Participant's Termination of Service, all Stock-Based Awards to the extent not vested shall be forfeited by the Participant to the Company unless determined otherwise by the Committee, as set forth in the Participant's Award Agreement. Any such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Stock-Based Awards issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination.

11.1    Settlement of EICP Awards. Pursuant to the EICP and elections made by eligible participants thereunder, annual incentive compensation awards deemed to be invested in the “Commerce Stock Account” under the EICP shall be settled in unrestricted Shares under this Plan at the time and in the manner prescribed by the EICP.

12.1    Deferrals. To the extent consistent with the requirements of section 409A of the Code, the Committee may provide in an Award Agreement or another document that a Participant is permitted to defer receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award. Any such deferral election shall be subject to such rules and procedures as shall be determined by the Committee.

12.2    No Effect on Employment or Service. Nothing in the Plan shall interfere with or limit in any way the right of the Company or any Subsidiary to terminate any Participant's employment or service at any time, with or without Cause. Employment with the Company or any Subsidiary is on an at-will basis only, unless otherwise provided by an applicable employment or service agreement between the Participant and the Company or any Subsidiary, as the case may be.

12.3    Participation. No Participant shall have the right to be selected to receive an Award under the Plan, or, having been so selected, to be selected to receive a future Award.

12.4    Indemnification. Each person who is or shall have been a member of the Committee, or of the Committee, to the extent permitted under state law, shall be indemnified and held harmless by the Company against and from (a) any loss, cost, liability or expense (including attorneys' fees) that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan or any Award Agreement, and (b) from any and all amounts paid by him or her in settlement thereof, with the Company's prior written approval, or paid by him or her in satisfaction of any judgment in any such claim, action, suit or

proceeding against him or her; provided, however, that he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company's Certificate of Incorporation or Bylaws, by contract, as a matter of law or otherwise, or under any power that the Company may have to indemnify them or hold them harmless.

12.5    Successors. All obligations of the Company under the Plan, with respect to Awards granted hereunder, shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation or otherwise, of all or substantially all of the business or assets of the Company.

12.6    Beneficiary Designations. If permitted by the Committee, a Participant under the Plan may name a beneficiary or beneficiaries to whom any vested but unpaid Award shall be paid, or who may exercise an Award if applicable, in the event of the Participant's death. Each such designation shall revoke all prior designations by the Participant and shall be effective only if given in a form and manner acceptable to the Committee. In the absence of any such designation, any vested benefits remaining unpaid at the Participant's death shall be paid to the Participant's estate and, subject to the terms of the Plan and of the applicable Award Agreement, any unexercised vested Award may be exercised by the administrator, executor or the personal representative of the Participant's estate.

12.7    No Rights as Stockholder. Except to the limited extent provided in Sections 7.6 and 7.7, no Participant (nor any beneficiary thereof) shall have any of the rights or privileges of a stockholder of the Company with respect to any Shares issuable pursuant to an Award (or the exercise thereof), unless and until certificates representing such Shares shall have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Participant (or his or her beneficiary).

12.8    Investment Representation. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

12.9    Uncertificated Shares. To the extent that the Plan provides for issuance of certificates to reflect the transfer of Shares, the transfer of such Shares may be effected on a noncertificated basis, to the extent not prohibited by applicable law or the rules of any stock exchange.

12.10    Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award. The Committee shall determine whether cash, or Awards, or other property shall be issued or paid in lieu of fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated.

12.11    Delivery. Unless otherwise provided in an Award Agreement with respect to any Award that provides for delivery to the Participant, such as upon exercise or lapse of restrictions, the Company shall issue Shares or pay an amount due within a reasonable period of time after such exercise or lapse of restrictions, which shall mean a period of no less than thirty (30) days.

13.1    Amendment, Suspension, or Termination. The Board, in its sole discretion, may amend or terminate the Plan, or any part thereof, at any time and for any reason; provided, however, that if and to the extent required by law or to maintain the Plan's compliance with the Code, the rules of any national securities exchange (if applicable), or any other applicable law, any such amendment shall be subject to stockholder approval; and further provided, that no amendment shall permit the repricing, replacing or regranting of an Option either in connection with the cancellation of such Option or by amending an Award Agreement to lower the exercise price of such Option. The amendment, suspension or termination of the Plan shall not, without the consent of the Participant, alter or impair

any rights or obligations under any Award theretofore granted to such Participant. No Award may be granted during any period of suspension or after termination of the Plan.

13.2    Amendment of Awards. The Committee, at any time and from time to time, may amend any one or more Awards, provided that, except as otherwise set forth in this Plan, no amendment of an Award that would impair rights of a Participant under the Award shall be effective unless (a) the Company requests the consent of the Participant, and (b) the Participant consents in the manner approved by the Committee.

13.3    Duration of the Plan. This amendment and restatement of the Plan shall become effective on the Effective Date, and subject to Section 13.1 shall remain in effect until the tenth anniversary of the Effective Date; provided, however, that such expiration shall not affect Awards then outstanding, and the terms and conditions of the Plan shall continue to apply to such Awards.

14.1    Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or the exercise thereof), the Company shall have the power and the right to deduct or withhold from any amounts due to the Participant from the Company, or require a Participant to remit to the Company, an amount sufficient to satisfy Federal, state and local taxes (including the Participant's FICA obligation) required to be withheld with respect to such Award (or the exercise thereof).

14.2    Withholding Arrangements. The Committee, pursuant to such procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part, by (a) electing to have the Company withhold otherwise deliverable Shares, or (b) delivering to the Company Shares then owned by the Participant having a Fair Market Value equal to the amount required to be withheld. The amount of the withholding requirement shall be deemed to include any amount that the Committee agrees may be withheld at the time any such election is made, not to exceed the amount determined by using the maximum federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to be withheld is to be determined. The Fair Market Value of the Shares to be withheld or delivered shall be determined as of the date that the taxes are required to be withheld.

15.1    Change in Control. Except with respect to any Award that constitutes “deferred compensation” within the meaning of section 409A of the Code, an Award Agreement may provide or be amended by the Committee to provide that Awards granted under the Plan that are outstanding and not then exercisable or are subject to restrictions at the time of a Change in Control shall become immediately exercisable, and all restrictions shall be removed, as of such Change in Control, and shall remain as such for the remaining life of the Award as provided herein and within the provisions of the related Award Agreements or that Awards may terminate upon a Change in Control. For purposes of the Plan, a Change in Control means any of the following:

(a) any Person is or becomes the “beneficial owner” (within the meaning of Rule 13d-3 promulgated under Section 13 of the Securities Exchange Act of 1934 (the “Exchange Act”)), directly or indirectly, of securities of the Company (not including in the securities beneficially owned by such Person any securities acquired directly from the Company or its affiliates other than in connection with the acquisition by the Company or its affiliates of a business) representing 20% or more of either the then outstanding shares of Common Stock of the Company or the combined voting power of the Company's then outstanding securities; or

(b) the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, on January 28, 2005, constitute the Board and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to a consent solicitation, relating to the election of directors of the Company) whose appointment or election by the Board or nomination for election by the Company's stockholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were directors on January 28, 2005 or whose appointment, election or nomination for election was previously so approved; or

(c) there is consummated a merger or consolidation of the Company (or any direct or indirect subsidiary of the Company) with any other corporation, other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or any parent thereof), in combination with the ownership of any trustee or other fiduciary holding securities under an employee benefit plan of the Company, at least 80% of the combined voting power of the voting securities of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation, or (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no Person is or becomes the beneficial owner, directly or indirectly, of securities of the Company (not including in the securities beneficially owned by such Person any securities acquired directly from the Company or its subsidiaries other than in connection with the acquisition by the Company or its subsidiaries of a business) representing 20% or more of either the then outstanding shares of Common Stock of the Company or the combined voting power of the Company's then outstanding securities; or

(d) the stockholders of the Company approve a plan of complete liquidation or dissolution of the Company or there is consummated a sale or disposition by the Company of all or substantially all of the Company's assets, other than a sale or disposition by the Company of all or substantially all of the Company's assets to an entity, at least 80% of the combined voting power of the voting securities of which are owned by Persons in substantially the same proportions as their ownership of the Company immediately prior to such sale.

For purposes of the above definition of Change in Control, “Person” shall have the meaning set forth in Section 3(a)(9) of the Exchange Act, as modified and used in Sections 13(d) and 14(d) thereof, except that such term shall not include (i) the Company or any of its subsidiaries, (ii) a trustee or other fiduciary holding securities under an employee benefit plan of the Company or any of its subsidiaries, (iii) an underwriter temporarily holding securities pursuant to an offering of such securities, or (iv) a corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company.

15.2    Other Awards. An Award Agreement with respect to an Award that constitutes “deferred compensation” within the meaning of section 409A of the Code may provide that the Award shall vest upon a “change in control” as defined in section 409A of the Code.

16.1    Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular, and the singular shall include the plural.

16.2    Severability. In the event any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included.
