The Committee may delegate any of its authority hereunder to one or more employees, officers or directors of the Company, who shall be considered the “Committee” hereunder in all respects to the extent of such delegated authority. The Committee hereby delegates its authority under this Plan to each of the Company’s SVP, Chief Human Resources Officer and SVP, Chief Legal Officer & Corporate Secretary, each of whom may act as the “Committee” for all purposes under this Plan. The Committee may also appoint one or more agents as it deems necessary or appropriate to assist with the day-to-day operation and administration of the Plan.

Committee Responsibilities. The Committee shall interpret the Plan and make all other policy decisions relating to the operation of the Plan. The Committee may adopt such rules, guidelines and forms as it deems appropriate to implement the Plan. All questions of interpretation or application of the Plan shall be determined by the Committee and its decisions shall be final and binding upon all Participants or others claiming any rights or benefits under the Plan. Members of the Committee shall receive no compensation for their services in connection with the administration of the Plan. All expenses incurred in connection with the administration of the Plan shall be paid by the Company.

Accumulation Periods. The Committee shall establish the Accumulation Periods hereunder. The length of the initial Accumulation Periods under the Plan shall be monthly, regardless of the number of pay periods included in any given month, provided that the Committee may revise the length of the Accumulation Periods at any time.

Enrollment. Any individual who, on the day preceding the first day of an Accumulation Period, qualifies (or will qualify) as an Eligible Employee may elect to become a Participant in the Plan for such Accumulation Period (if administratively practicable, if not, the next Accumulation Period) by executing a payroll deduction election form in the form and at the time provided by the Company, which forms may be completed electronically if available (an “Election Form”).

Duration of Participation. Once enrolled in the Plan, a Participant who is an Eligible Employee shall continue to participate in the Plan until he or she ceases to be an Eligible Employee, withdraws from the Plan under Section 7 or reaches the end of the Accumulation Period in which such Participant’s contributions were discontinued under Section 6(c) or Section 10. Such Participant is not required to file any additional Election Forms in order to continue participation in the Plan. A Participant who is an Eligible Employee who discontinued contributions under Section 6(c) or withdrew from the Plan under Section 8 may again become a Participant, if he or she then is an Eligible Employee, by following the procedure described in subsection (b) above. A Participant who is an Eligible Employee whose contributions were discontinued automatically under Section 10 shall automatically resume participation in the Plan at the beginning of the first Accumulation Period in the next calendar year, if he or she then is an Eligible Employee.

Frequency of Payroll Deductions. A Participant who is an Eligible Employee may purchase shares of Stock under the Plan solely by means of payroll deductions pursuant to a properly completed Election form. Payroll deductions, as designated by a Participant pursuant to subsection (b) below, shall occur on each payday during an Accumulation Period in which the Participant participates in the Plan.

Amount of Payroll Deductions. An Eligible Employee shall designate on the Election Form the portion of his or her Compensation that he or she elects to have withheld for the purchase of Stock hereunder. Such portion may be a whole percentage of the Eligible Employee’s compensation, but not less than 1% nor more than 50%. The Committee may, in its discretion, establish a minimum contribution amount per Accumulation Period. See Section 10 for the maximum allowable contribution amount per calendar year.

Changing Payroll Deductions. Payroll contributions may not be increased or decreased (other than decreased to 0%), during an Accumulation Period. If a Participant who is an Eligible Employee wishes to discontinue his or her contributions entirely, he or she must follow the procedure for withdrawal under Section 7 of the Plan.

Withdrawal. Each Participant who is an Eligible Employee may withdraw from an Accumulation Period under the Plan by filing a new Election Form. Such withdrawal may be elected at any time, and will be effective as soon as administratively practical following receipt thereof. A Participant who has withdrawn from the Plan may resume contributions for a future Accumulation Period by filing a new Election Form if he or she then is an Eligible Employee.

Return of Payroll Deductions. Upon withdrawal from the Plan and unless otherwise determined by the Committee, any accumulated payroll deductions shall be returned, without interest, to the withdrawn Eligible Employee and his or her interest in the Plan shall terminate.

Plan Accounts. The Company shall establish a bookkeeping account, which may be through a third-party administrator, in the name of each Participant (a “Plan Account”). All payroll deductions made for an Eligible Employee will be credited to his or her Plan Account under the Plan; no interest shall accrue on any payroll deductions. An Eligible Employee may not make any separate cash payment into his or her Plan Account and payment for shares of Stock purchased under the Plan by any Eligible Employee may not be made in any form other than by payroll deduction from the Plan Account.

Purchase Price. The Purchase Price for each share of Stock purchased on a Purchase Date shall be the price per share actually paid on the open market for each such share of Stock, or in the event that such shares of Stock are issued from previously authorized but unissued or treasury shares, shall be the closing price per share of Stock, as determined by the Committee, on the trading date immediately preceding the date of purchase.

Matching Contributions. On each Purchase Date, the Company shall make a contribution of fully vested Stock to each Participant equal to 15% of the number of shares of Stock purchased on behalf of such Participant through this Plan on such Purchase Date (rounded up to the nearest whole share). Such Company contributed shares of Stock may be purchased on the open market by the Company or issued from authorized but unissued or treasury shares. In accordance with Section 19 hereof, the Company shall be permitted to issue such shares of Stock net of applicable taxes.

Number of Shares Purchased via Participant Contribution. On each Purchase Date, the Company shall apply the funds then credited to each Participant’s Plan Account to the purchase of shares of Stock. As of each such Purchase Date, each such Participant shall purchase the number of shares of Stock calculated in accordance with this subsection (d), unless the Participant has previously elected to withdraw from the Plan in accordance with Section 7; provided, however, that no Stock shall be purchased on a Purchase Date on behalf of any Participant whose participation in the Plan was terminated prior to such Purchase Date. On each Purchase Date, the amount of funds then in the Participant’s Plan Account shall be divided by the Purchase Price, and the number of shares that results shall be purchased with the funds credited to the Participant’s Plan Account. Any fractional share, as calculated under this subsection (d), shall be rounded down to the next lower whole share.

Issuance of Stock. Promptly following each Purchase Date, the number of shares of Stock purchased by each Participant shall be deposited into the Participant’s account established in the Participant’s name at a stock brokerage or other financial services firm designated by the Company.

Unused Cash Balances. Any amount remaining in the Participant’s Plan Account that represents the Purchase Price for any fractional share shall be carried over in the Participant’s Plan Account to the next Accumulation Period. Any amount remaining in the Participant’s Plan Account that represents the Purchase Price for whole shares that could not be purchased by reason of Section 10 shall be refunded to the Participant in cash, without interest.

Holding Period. Any shares of Stock acquired pursuant to the Plan at any time, may not be disposed of by the Participant, whether by sale, exchange, gift, or other transfer of legal title, until the earlier of (i) the date the Participant has held the Stock received under this Plan for a period of at least six months from the applicable Purchase Date or (ii) the date of the Participant’s termination of employment with all Participating Employers.

Designation. A Participant may file a designation of a beneficiary on a form provided by the Company who is to receive the cash, if any, that remains allocated to the Participant’s Plan Account in the event of such Participant’s death. Such designation of beneficiary may be changed by the Participant at any time by filing a new beneficiary designation on a form provided by the Company.

No Designation. In the event of the death of a Participant in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company or then surviving, then to such other person as the Company may designate.
