The Exercise Price shall be payable to the Company in full in cash or its equivalent (including, but not limited to, by means of, a broker-assisted cashless exercise). The Committee, in its sole discretion, also may permit exercise (a) by tendering previously acquired Shares having an aggregate Fair Market Value at the time of exercise equal to the aggregate Exercise Price of the Shares with respect to which the Option is to be exercised, or (b) by any other means which the Committee, in its sole discretion, determines to both provide legal consideration for the Shares, and to be consistent with the purposes of the Plan.

As soon as practicable after receipt of a written notification of exercise and full payment for the Shares with respect to which the Option is exercised, the Company shall deliver to the Participant Shares (which may be in book entry or certificate form) for such Shares with respect to which the Option is exercised.

Any such deferral elections shall be subject to such rules and procedures as shall be determined by

13

the Committee in its sole discretion and shall be done in a manner expected not to result in taxation under Section 409A of the Code.

(2) Notwithstanding any provision in this Plan or any Award Agreement, in the event of a Change of Control pursuant to paragraph (a) or (b) of Section 2.8, or in the event of a Change of Control pursuant to paragraph (c) or (d) of Section 2.8 in connection with which the holders of Shares receive consideration other than shares of common stock that are registered under Section 12 of the 1934 Act, each outstanding Award shall be surrendered to the Company by the holder thereof, and each such Award shall immediately be canceled by the Company, and the holder shall receive, within ten days of the occurrence of a Change of Control (or such later date as may be required for compliance with Section 409A of the Code), a cash payment from the Company in an amount equal to (i) in the case of an Option, the number of Shares then subject to such Option, multiplied by the excess, if any, of the Fair Market Value of a Share on the date of occurrence of the Change of Control, over the purchase price per Share subject to the Option, (ii) in the case of an SAR other than a tandem SAR, the number of Shares then subject to such SAR, multiplied by the excess, if any, of the Fair Market Value of a Share on the date of occurrence of the Change of Control, over the base price of the SAR, (iii) in the case of a Restricted Stock Award or Performance Share Award, the number of Shares or the number of Performance Shares, as the case may be, then subject to such Award, multiplied by the greater of (A) the highest per Share price offered to stockholders of the Company in any transaction whereby the Change of Control takes place or (B) the Fair Market Value of a Share on the date of occurrence of the Change of Control. Notwithstanding the foregoing, in the event of a Change in Control that does not constitute a “change in control event” as defined for purposes of Section 409A of the Code, the payment with respect to Performance Shares described in clause (iii) of the preceding sentence shall not be paid until the time prescribed in Section 8.2.3 or 9.2.3, as applicable.

In the event of a Change of Control, each tandem SAR shall be surrendered by the holder thereof and shall be canceled simultaneously with the cancellation of the related Option.

10.12 Restrictions on Shares. Each Award made hereunder shall be subject to the requirement that if at any time the Company determines that the listing, registration or qualification of the Shares subject to such Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the exercise or settlement of such Award or the delivery of Shares thereunder, such Award shall not be exercised or settled and such Shares shall not be delivered unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company may require that certificates evidencing shares delivered pursuant to any Award made hereunder bear a legend in indicating that the sale, transfer or other disposition thereof by the holder is prohibited except in compliance with the Securities Act of 1933, as amended, and the rules and regulations thereunder.

10.13 Dividend Equivalents Rights . Any Participant selected by the Committee may be granted Dividend Equivalent Rights based on the dividends declared on Shares that are subject to any Award, to be credited as of dividend payment dates, during the period between the date the Award is granted and the date the Award is exercised, vests or expires, as determined by the Committee. Such Dividend Equivalent Rights shall be converted to cash or additional Shares by such formula and at such time and subject to such limitations as may be determined by the Committee. Notwithstanding the foregoing, if any Award for which Dividend Equivalent Rights have been granted has its vesting or grant dependent upon the achievement of one or more Performance Measures, then the Dividend Equivalent Rights shall accrue and only be paid to the extent the Award becomes vested. Under no circumstances may Dividend Equivalent Rights be granted for any Option or SAR.

10.14 No Representations or Warranties Regarding Tax Affect . Notwithstanding any provision of the Plan to the contrary, the Company and its Affiliates, the Board and the Committee neither represent nor warrant the tax treatment under any federal, state, local or foreign laws and regulations thereunder (individually and collectively referred to as the “Tax Laws” ) of any Award granted or any amounts paid to any Participant under the Plan including, but not limited to, when and to what extent such Awards or amounts may be subject to tax, penalties and interest under the Tax Laws.

c. A Participant may withdraw from the Plan as provided in Section 9, which will terminate his or her payroll deductions for the Purchase Period in which such withdrawal occurs. The Committee may, in its discretion, limit the number of rate changes by Participants during a Purchase Period.

Unless otherwise determined by the Committee, Shares delivered to a Participant hereunder may not be assigned, transferred, pledged or otherwise disposed of in any way by the Participant during the six month period following such delivery to the Participant (other than by will, the laws of descent and distribution) and the Shares shall bear a legend denoting such restrictions as may be determined by the Committee to be appropriate.

9. Withdrawal; Termination of Employment.

a. A Participant may withdraw at any time all, but not less than all, cash amounts in his or her account under the Plan that have not been used to purchase Shares by giving written notice to the Company prior to the next occurring Exercise Date. All such cash amount credited to such Participant’s account shall be paid to such Participant promptly after receipt of such Participant’s notice of withdrawal and such Participant’s option for the Purchase Period in which the withdrawal occurs shall be automatically terminated. No further payroll deductions for the purchase of Shares will be made for such Participant during such Purchase Period.

b. Upon termination of a Participant’s Continuous Status as an Employee during a Purchase Period for any reason, including voluntary termination, retirement or death, the cash amounts credited to such Participant’s account that have not been used to purchase Shares shall be returned to such Participant and such Participant’s option for the Purchase Period in which the termination occurs will be automatically terminated.

c. A Participant’s withdrawal from a Purchase Period will not have any effect upon such Participant’s eligibility to participate in a succeeding Purchase Period or in any similar plan which may hereafter be adopted by the Company.

10. Interest. No interest shall accrue on or be payable with respect to any cash amount credited to a Participant under the Plan.

11. Shares.

a. Subject to adjustment as provided in Section 16 hereof, the maximum number of Shares which shall be reserved for sale under the Plan shall be 100,000 Shares. If any option granted under the Plan shall expire or terminate for any reason without having been exercised in full or shall cease for any reason to be exercisable in whole or in part, the unpurchased Shares subject thereto shall again be available under the Plan. Such reserved Shares shall be either authorized and unissued Shares or Shares which have been reacquired by the Company. If the total number of Shares which would otherwise be purchased pursuant to options granted hereunder on an Exercise Date exceeds the number of Shares then available under the Plan (after deduction of all Shares for which options have been exercised or are then outstanding), the Committee shall make a pro rata allocation of the Shares remaining available for option grant in as uniform a manner as shall be practicable and as it shall determine to be equitable and in compliance with the provisions of Section 423 of the Code. In such event, the Committee shall give written notice to each Participant of such reduction of the number of option Shares affected thereby and shall similarly reduce the rate of payroll deductions, if necessary.

b. Shares to be delivered to a Participant under the Plan will be registered in the name of the Participant or, at the election of the Participant, in the name of the Participant and another person as joint tenants with rights of survivorship.

12. Administration. The Plan shall be administered by the Committee, and the Committee may select administrator(s) to whom its duties and responsibilities hereunder may be delegated. The Committee shall have full power and authority, subject to the provisions of the Plan, to promulgate such rules and regulations as it deems necessary for the proper administration of the Plan, to interpret the provisions and supervise the administration of the Plan, and to take all action in connection therewith or in relation thereto as it deems necessary or advisable. Except as otherwise provided by the Committee, each Employer shall be charged with all expenses incurred in the administration of the Plan with respect to such Employer’s Employees. No member of the Committee shall be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan, and all members of the Committee shall be fully indemnified by the Company with respect to any such action, determination or interpretation. All decisions, determinations and interpretations of the Committee shall be final and binding on all persons, including the Company, the Participant (or any person claiming any rights under the Plan from or through any Participant) and any shareholder.

13. Transferability. Neither cash amounts credited to a Participant’s account nor any rights with regard to the exercise of an option or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way by the Participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with Section 9 hereof.

14. Use of Funds. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such funds.

15. Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to Participants as soon as practicable following each Purchase Period, which statements will set forth the amounts of payroll deductions, the per Share purchase price, the number of Shares purchased and the remaining cash balance, if any.

16. Effect of Certain Changes. In the event of a Change in Capitalization, the Committee shall conclusively determine the appropriate equitable adjustments, if any, to be made under the Plan, including without limitation adjustments to the number of Shares which have been authorized for issuance under the Plan but have not yet been placed under option, as well as the price per Share covered by each option under the Plan which has not yet been exercised.

17. Term of Plan. Subject to the Board’s right to discontinue the Plan (and thereby end its Term) pursuant to Section 18 hereof, the Term of the Plan (and its last Purchase Period) shall end on June 30, 2022. Upon any discontinuance of the Plan, unless the Committee shall determine otherwise, any assets remaining in the Participants’ accounts under the Plan shall be delivered to the respective Participant (or the Participant’s legal representative) as soon as practicable.

18. Amendment to and Discontinuance of Plan. The Board may at any time amend, suspend or discontinue the Plan. Except as provided in Section 16 hereof, no such suspension or discontinuance may adversely affect options previously granted and no amendment may make any change in any option theretofore granted which adversely affects the rights of any Participant which accrued prior to the date of effectiveness of such amendment without the consent of such Participant. No amendment shall be effective unless it receives the requisite approval of the shareholders of the Company if such shareholder approval of such amendment is required to comply with Section 423 of the Code or to comply with any other applicable law, regulation or stock exchange or national or international quotation system rule.

19. Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

20. Regulations and Other Approvals; Governing Law.

a. This Plan and the rights of all persons claiming hereunder shall be construed and determined in accordance with the laws of the State of Delaware without giving effect to the choice of law principles thereof, except to the extent that such law is preempted by federal law.

b. The obligation of the Company to sell or deliver Shares with respect to options granted under the Plan shall be subject to all applicable laws, rules and regulations, including all applicable federal and state securities laws, and the obtaining of all such approvals by governmental agencies as may be deemed necessary or appropriate by the Committee.

21. Withholding of Taxes. If the Participant makes a disposition, within the meaning of Section 424(c) of the Code and regulations promulgated thereunder, of any Share or Shares issued to such Participant pursuant to such Participant’s exercise of an option, and such disposition occurs within the two-year period commencing on the applicable Offering Date or within the one-year period commencing on the day after the applicable Exercise Date, such Participant shall, within ten (10) days of such disposition, notify the Company thereof and thereafter immediately deliver to the Company any amount of Federal, state or local income taxes and other amounts which the Company informs the Participant the Company is required to withhold.

22. Employment At-Will and Limitation of Rights. This Plan is strictly a voluntary undertaking on the part of the Company and shall not constitute a contract between the Employer and any person, or consideration for, or an inducement or condition of, the employment of any person. Nothing contained in the Plan shall alter or supersede the employment at-will relationship, or other employment agreement provisions if applicable, between the Employer and its Employees.
