1.    Relationship to the Plan. This Option is subject to all of the terms, conditions and provisions of the Plan and administrative interpretations thereunder, if any, that have been adopted by the Committee.

5.    Forfeiture or Repayment Resulting from Forfeiture Event.

(a)    Forfeiture of Unexercised Option. If a Forfeiture Event occurs during the Optionee’s Employment or within three years following Optionee’s termination of Employment, the Committee may, but is not obligated to, cause all or any portion of the Option granted under this Award Agreement to be forfeited.

(b)    Repayment of Spread on Exercised Option. If a Forfeiture Event occurs during the Optionee’s Employment or within three years following Optionee’s termination of Employment, the Committee may, but is not obligated to, require the Optionee to pay to the Corporation an amount in cash up to (but not in excess of) the difference between the Grant Price and market price of the Option on the date of exercise with respect to any shares for which the Option has been exercised (the “Forfeited Spread Amount”). Any Forfeited Spread Amount shall be paid by the Participant within sixty (60) days of receipt from the Corporation of written notice requiring payment of such Forfeited Spread Amount.

(c)     Application of Forfeiture Provisions. This Section 5 shall apply notwithstanding any provision of this Award Agreement to the contrary and is meant to provide the Corporation with rights in addition to any other remedy which may exist in law or in equity. This Section 5 shall not apply to the Optionee following the effective time of a Change in Control.

6.    Exercise of Option. Subject to the limitations set forth herein and in the Plan, this Option may be exercised in whole or in part by providing notice of the number of Option Shares to be exercised to the Committee or its delegate, which shall include any outside firm engaged by the Corporation to administer the Plan. The Option must be exercised in accordance with the methods and at the times set by the

Committee or its delegate, and by the Optionee’s delivery of the Grant Price or of such authorizations as may be required. The Grant Price for all shares of Common Stock purchased upon the exercise of this Option, or a portion of this Option, shall be paid in full at the time of such exercise. Such payment may be made in cash or by tendering shares of Common Stock having a value on the date of exercise equal to the Grant Price. If the Optionee makes payment of the Grant Price by tendering shares of Common Stock, such Common Stock must be registered in the sole name of the Optionee on the exercise date or an appropriate stock power acceptable to the Corporation to transfer such stock to the sole name of the Optionee must be provided at the time of exercise. Depending on its source, Common Stock tendered in the exercise of this Option must have met the appropriate holding period required by current tax, accounting, legal, or other applicable rules and regulations. Subject to any administrative limitations on exercise of Stock Options or permissible methods of option exercise imposed by the Committee or its delegate, this Option may also be exercised by a “net-share settlement” method or “cashless exercise” method for exercising outstanding nonqualified stock options. The Committee or its delegate, in its sole discretion and judgment, may limit the extent to which shares of Common Stock can be used in exercise of this Option or limit the use of any method or time of option exercise. Further, the Committee or its delegate, in its sole discretion and judgment, may, but shall have no obligation to, exercise this Option on behalf of the Optionee immediately prior to the expiration of this Option if the Fair Market Value of a share of Common Stock exceeds the Grant Price on such date. For purposes of determining the amount, if any, of the purchase price satisfied by payment in Common Stock, such Common Stock shall be valued at its Fair Market Value on the date of exercise. Upon receipt of the purchase price, the Corporation or its designated representative shall issue or cause to be issued to the Optionee a number of shares of Common Stock equal to the number of Option Shares then exercised.

7.    Taxes. In all cases, the Optionee will be responsible to pay all required withholding taxes associated with this Option. Pursuant to Section 10 of the Plan, the Corporation or its designated representative (which may be a Subsidiary) shall have the right to withhold applicable taxes from the shares of Common Stock otherwise payable to the Optionee upon exercise of the Option or from compensation otherwise payable to the Optionee at the time of exercise, to sell or permit the sale of shares of Common Stock to pay such applicable taxes, or to take such other action as may be necessary in the opinion of the Corporation to satisfy all obligations for withholding.

8.    Shareholder Rights. The Optionee shall have no rights of a shareholder with respect to the Option Shares unless and until such time as the Option has been exercised and shares of Common Stock have been issued to the Optionee in conjunction with the exercise of the Option.

9.    Nonassignability. During the Optionee’s lifetime, the Option may be exercised only by the Optionee or by the Optionee’s guardian or legal representative. Upon the Optionee’s death, the Option shall be transferred to the Optionee’s designated beneficiary on file with the Plan’s third party stock plan administrator or, if none, to the Optionee’s estate. Otherwise, the Optionee may not sell, transfer, assign, pledge or otherwise encumber any portion of the Option, and any attempt to sell, transfer, assign, pledge, or encumber any portion of the Option shall have no effect.

10.    No Employment Guaranteed. Nothing in this Award Agreement shall give the Optionee any rights to (or impose any obligations for) continued Employment by the Corporation or any Subsidiary

thereof or successor thereto, nor shall it give such entities any rights (or impose any obligations) with respect to continued performance of duties by the Optionee.

11.    Modification of Agreement. Any modification of this Award Agreement shall be binding only if evidenced in writing and signed by an authorized representative of the Corporation, provided that no modification may, without the consent of the Optionee, adversely affect the rights of the Optionee hereunder. Without the consent of the Optionee, this Award Agreement may be amended or supplemented (i) to cure any ambiguity or to correct or supplement any provision herein which may be defective or inconsistent with any other provision herein, or (ii) to add to the covenants and agreements of the Corporation for the benefit of the Optionee or to add to the rights of the Optionee or to surrender any right or power reserved to or conferred upon the Corporation in this Award Agreement; provided, in each case, that such changes or corrections shall not adversely affect the rights of the Optionee under this Award Agreement without the Optionee’s consent, or (iii) to make such other changes as the Corporation, upon advice of counsel, determines are necessary or advisable because of the adoption or promulgation of, or change in or of the interpretation of, any law or governmental rule or regulation, including any applicable federal or state securities or tax laws.

12.Data Privacy.
