1. Exercise of Option. Except as provided in paragraphs 4, 5, 6, 11 and 12 of these Terms and Conditions, this Option shall be exercisable as set forth in the Vesting Schedule for each full year, up to a total of four (4) full years, that Optionee continues to be employed by the Company after the date of this Agreement. Once this Option has become exercisable with respect to any portion of the total number of shares in accordance with the preceding sentence, it shall continue to be exercisable with respect to such shares until the termination of Optionee’s rights hereunder pursuant to paragraphs 4, 5 or 6, or until the Expiration Date. A partial exercise of this Option shall not affect Optionee’s right to exercise subsequently this Option with respect to the remaining shares that are exercisable, subject to the conditions of the 2007 Stock Incentive Plan (Plan) and this Agreement.

2. Method of Exercising and Payment for Shares. This Option may be exercised only by written notice delivered to the attention of the Company’s Secretary at the Company’s principal office. The written notice shall specify the number of shares being acquired pursuant to the exercise of the Option when such Option is being exercised in part in accordance with the Vesting Schedule. The exercise date shall be the date such notice is received by the Company. Such notice shall be accompanied by payment of the Option price in full for each share (a) in cash (United States dollars) or by cash equivalent acceptable to the Company, or (b) by a cashless exercise pursuant to Section IX(2) of the Plan.

(b) The Participant may transfer the Option during his or her lifetime for no consideration to or for the benefit of the Participant’s Immediate Family, subject to such limits as the Committee may establish, and the transferee shall remain subject to all the terms and conditions applicable to the Option prior to such transfer. The foregoing right to transfer the Option shall apply to the right to consent to amendments to this Agreement and, in the discretion of the Committee, shall also apply to the right to transfer ancillary rights associated with the Option.

(c) The term “Immediate Family” shall mean Participant’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships, any person sharing the Participant’s household (other than a tenant or employee), a trust in which these persons have more than fifty percent of the beneficial interest, a foundation in which these persons (or the Participant) control the management of assets, and any other entity in which these persons (or the Participant) own more than fifty percent of the voting interests. The following transactions are not prohibited transfers for consideration: (i) a transfer under a domestic relations order in settlement of marital property rights; and (ii) a transfer to an entity in which more than fifty percent of the voting interests are owned by the Immediate Family (or the Participant) in exchange for an interest in that entity.

4. Exercise in the Event of Death. This Option shall be exercisable in full in the event that Optionee dies while employed by the Company or an Affiliate and prior to the Expiration Date of this Option. In that event, this Option may be exercised by Optionee’s estate, or the person or persons to whom his rights under this Option shall pass by will or the laws of descent and distribution. Optionee’s estate or such persons must exercise this Option, if at all, within one year of the date of Optionee’s death or during the remainder of the period preceding the Expiration Date, whichever is shorter, but in no event may the Option be exercised prior to the expiration of six (6) months from the date of the grant of the Option.

5. Exercise in the Event of Permanent and Total Disability. This Option shall be exercisable in full if Optionee becomes Disabled while employed by the Company or an Affiliate and prior to the Expiration Date of this Option. In that event, Optionee must exercise this Option, if at all, within one year of the date he becomes Disabled or during the remainder of the period preceding the Expiration Date, whichever is shorter, but in no event may the Option be exercised prior to the expiration of six (6) months from the date of the grant of the Option.

6. Exercise After Termination of Employment. In the event that the Optionee retires from employment with the Company after attaining age 62 and serving at least 10 consecutive years with the Company or an Affiliate or predecessor thereof, then this Option shall be exercisable in full but must be exercised by the Optionee, if at all, within one year following his retirement date or during the remainder of the period preceding the Expiration Date, whichever is shorter, but in no event may the Option be exercised prior to the expiration of six (6) months from the date of the grant of the Option. In all events other than those events addressed in paragraphs 4 or 5 or the foregoing sentence of this paragraph 6, in which Optionee ceases to be employed by the Company: (a) Optionee, subject to the provisions of paragraph 12, may exercise the Option in whole or in part with respect to that number of shares which are exercisable by him under the Vesting Schedule on the date his employment terminated, and (b) this Option must be exercised by Optionee, if at all, within ninety (90) days following the date upon which he ceases to be employed by the Company or during the remainder of the period preceding the Expiration Date, whichever is shorter, but in no event may the Option be exercised prior to the expiration of six (6) months from the date of the grant of the Option.

7. Fractional Shares. Fractional shares shall not be issuable hereunder, and when any provision hereof may entitle Optionee to a fractional share such fraction shall be disregarded.

8. No Right to Continued Employment. This Option does not confer upon Optionee any right with respect to continuance of employment by the Company or an Affiliate, nor shall it interfere in any way with the right of the Company or an Affiliate to terminate his employment at any time.

9. Investment Representation. Optionee agrees that, unless such shares previously have been registered under the Securities Act of 1933, as amended (the “Securities Act”): (i) any shares purchased by him hereunder will be purchased for investment and not with a view to distribution or resale and (ii) until such registration, certificates representing such shares may bear an appropriate legend to assure compliance with the Securities Act. This investment representation shall terminate when such shares have been registered under the Securities Act.

10. Change in Capital Structure. Subject to any required action by the shareholders of the Company, the number of shares of Common Stock covered by this Option, and the price per share thereof, shall be proportionately adjusted by the Company for any increase or decrease in the number of issued and outstanding shares of Common Stock of the Company resulting from any stock dividend (but only on the Common Stock), stock split, combination, reclassification, recapitalization or general issuance to holders of Common Stock of rights to purchase Common Stock at substantially below its then fair market value, or any change in the number of such shares outstanding effected without receipt of cash or property or labor or services by the Company, or any spin-off or other distribution of assets to shareholders.

In the event of a change in the Common Stock of the Company as presently constituted, which is limited to a change of all or a part of its authorized shares without par value into the same number of shares with a par value, or any subsequent change into the same number of shares with a different par value, the shares resulting from any such change shall be deemed to be the Common Stock within the meaning of the Plan.

The grant of this Option pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge or to consolidate or to dissolve, liquidate or sell, or transfer all or any part of its business or assets.

11. Change of Control. Notwithstanding any other provision of this Agreement to the contrary, in the event of a Change of Control, the provisions of Section 12.03 of the Plan shall apply to this Option.

12. Forfeiture of Certain Gains.

For purposes of this paragraph, “Cause” shall have the meaning ascribed to it in any employment agreement between the Optionee and the Company that is in effect at the time of termination and, if no such agreement exists, it shall mean:

(i) the willful and continued failure of the Optionee to perform substantially the Optionee’s duties with the Company or one of its affiliates (other than any such failure resulting from incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to the Optionee by the Company which specifically identifies the manner in which the Company believes that the Optionee has not substantially performed the Optionee’s duties, or

(ii) the willful engaging by the Employee in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company.

(b) Forfeiture if Optionee Engages in Certain Activities.

(c) Right of Set-off. Optionee hereby consents to a deduction from any amounts owed by the Company to Optionee from time to time (including amounts owed as wages or other compensation, fringe benefits or vacation pay, to the extent of any amounts Optionee owes the Company under paragraphs 12(a) and (b).
