10.Purchase of Shares.  If as of any Exercise Date there is credited to the Stock Purchase Account of a Participant an amount at least equal to the Purchase Price of one share of Common Stock, as determined in Section 9 hereof, for the Offering which expires on such Exercise Date, the Participant shall purchase from the Company at such Purchase Price the largest number of whole shares of Common Stock which can be purchased with the amount credited to his Stock Purchase Account, or such lesser number of shares the Committee may from time to time establish as the maximum number of shares that a Participant may purchase in such Offering.

11.Expiration of Offering.  As of each Exercise Date the amount credited to the Stock Purchase Account of each Participant in the Offering which expires on such Exercise Date shall be charged with the aggregate Purchase Price of the shares of Common Stock purchased by the Participant on such Exercise Date.  The remaining balance credited to his Stock Purchase Account shall be refunded to each Participant who files notice of his election for refund prior to such Exercise Date in the manner provided in Section 23 hereof.  If no such notice is filed by a Participant and he has not withdrawn from the Plan in accordance with Section 13 hereof, any remaining balance credited to his Stock Purchase Account shall be credited to his Stock Purchase Account for the next succeeding Offering hereunder.

12.Issuance of Shares, Stock Certificate.

12.1The shares of Common Stock purchased by a Participant on an Exercise Date shall, for all purposes, be deemed to have been sold at the close of business on such Exercise Date.  Prior to that time the Participant shall have none of the rights or privileges of a stockholder of the Company with respect to such shares.

12.2As soon as practicable after each Exercise Date, the Company shall issue and deliver a certificate for the number of shares of Common Stock purchased by a Participant on such Exercise Date, which certificate shall be registered either in the Participant’s name or jointly in the names of the Participant and his spouse, with the right of survivorship, as the Participant shall designate in a written notice to the Company pursuant to Section 23 hereof.  The Participant may change such designation at any time by filing notice of the change in accordance with Section 23 hereof.

13.Voluntary Withdrawal from Plan.  A Participant other than an officer or director of the Company who is subject to Section 16(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) may withdraw from the Plan at any time by filing notice of withdrawal in the manner provided in Section 23 hereof.  Upon a Participant’s withdrawal, the entire amount credited to his Stock Purchase Account shall be refunded to him.  Any Participant who withdraws from the Plan may again become a Participant hereunder with respect to a future Offering Period by filing notice in accordance with Section 5 hereof.  An officer or director of the Company who is subject to Section 16(b) of the Exchange Act may withdraw from the Plan only with respect to a future Offering Period, unless the Committee shall have made other provision for exempting transactions under the Plan by such persons from Section 16(b) of the Exchange Act in advance of the Offering Period in which any such notice of withdrawal is filed.

14.Involuntary Withdrawal from Plan.  If a Participant ceases to be an Employee by reasons of clauses (a), (b) or (c) of Section 2.8 hereof, the entire credit balance in his Stock Purchase Account as of the effective date on which he so ceased to be an Employee shall be used to purchase shares of Common Stock pursuant to Sections 9 and 10 hereof as of the next Exercise Date and any remaining balance credited to his Stock Purchase Account shall be refunded to him.

15.Termination of Employment.  If a Participant ceases to be an Employee other than by reason of clauses (a), (b) or (c) of Section 2.8 hereof, the entire credit balance in his Stock Purchase Account shall be refunded to him.  If a Participant dies, the entire credit balance in his Stock Purchase Account shall be paid over to his estate.

16.Procedure if Insufficient Shares Available.  In the event that on any Exercise Date the aggregate funds available for the purchase of shares of Common Stock pursuant to Section 9 hereof would purchase a number of shares in excess of the number of shares then available for purchase under the Plan, the Committee shall proportionately reduce the number of shares which would otherwise be purchased by each Participant on such Exercise Date in order to eliminate such excess, the Plan shall automatically terminate immediately after such Exercise Date and any remaining balance credited to the Stock Purchase Account of a Participant shall be refunded to such Participant.

17.Limitation on Right to Purchase.  Anything herein to the contrary notwithstanding, if at any time when any person is entitled to complete the purchase of any shares pursuant to this Plan, taking into account such person’s rights, if any, to purchase stock under all other stock purchase plans of the Company or any Subsidiary, the result would be that during the then current calendar year such person would have first become entitled to purchase under this Plan and all such other plans a number of shares of stock which would exceed the maximum number of shares permitted by the provisions of Section 423(b)(8) of the Code, then the number of shares which such person shall be entitled to purchase pursuant to this Plan shall be reduced by the number which is one more than the number of shares which represents the excess.

18.Rights Not Transferable.  Rights to purchase shares under this Plan are exercisable only by the Participant during his lifetime and are not transferable.  If a Participant attempts to transfer his rights to purchase shares under the Plan, he shall be deemed to have requested withdrawal from the Plan and the provisions of Section 13 hereof shall apply with respect to such Participant.

19.Administration of the Plan.  Subject to the general control of, and superseding action by, the Board of Directors, the Committee shall have full power to administer the Plan.  The Committee shall adopt Rules not inconsistent with the provisions of the Plan for its administration, including the form of all notices required hereunder.  The Committee’s interpretation and construction of the Plan and Rules shall, subject as aforesaid, be final and conclusive.

20.Amendment of the Plan.  The Board of Directors may at any time, or from time to time, alter or amend the Plan in any respect, except that, without approval of the stockholders, no amendment may (i) change the number of shares reserved under the Plan other than as provided in Section 21 hereof, (ii) reduce the Purchase Price per share as determined under Section 9 hereof other than as provided in Section 21

hereof, or (iii) permit any person who is not an Employee to participate in the Plan.

21.Recapitalization and Corporate Reorganization.

21.1The aggregate number of shares of Common Stock reserved for purchase under the Plan as provided in Section 3 hereof and the Purchase Price per share as provided in Section 9 hereof shall be appropriately adjusted to reflect any increase or decrease in the number of issued shares of Common Stock resulting from a subdivision or consolidation of shares or other capital adjustment, or the payment of a stock dividend, or other increase or decrease in such shares effected without receipt of consideration by the Company.

21.2Subject to any required action by the stockholders, if the Company shall be the surviving or resulting corporation in any merger or consolidation, any Offering hereunder shall pertain to and apply to the shares of stock of the Company, but a dissolution or liquidation of the Company or a merger or consolidation in which the Company is not the surviving or the resulting corporation, shall cause the Plan and any Offering hereunder to terminate and the entire amount credited to the Stock Purchase Account of each Participant hereunder shall be paid to such Participant.

22.Expiration and Termination of the Plan.  The Plan shall continue in effect through June 30, 2015, unless terminated prior thereto pursuant to Section 21 hereof, provided that the Board of Directors shall have the right to terminate the Plan at any time.  In the event of the expiration of the Plan or its termination pursuant to Section 21 hereof, the entire amount credited to the Stock Purchase Account of each Participant hereunder shall be refunded to the Participant.

23.Notice.  Any notice which a Participant files pursuant to this Plan shall be in the appropriate form prescribed by the Rules or, if no provision is made in such Rules for the particular kind of notice in question, such notice shall be in writing and shall be delivered by hand or mailed, postage prepaid, to the secretary of the Committee, or his designee.

24.Repurchase of Stock.  The Company shall not be required to repurchase from any Participant shares of Common Stock which he acquires under this Plan.

25.Alternative Contribution Methods.  Anything herein to the contrary notwithstanding, in the event that authorized payroll deductions from Employees’ Compensation are not permitted by reason of the provisions of local law applicable to the Company or any Subsidiary, the Committee shall adopt an appropriate alternative method pursuant to which affected Employees may make payment for shares of Common Stock purchased hereunder which would otherwise have been made pursuant to Section 6 hereof. Payments made hereunder shall be deemed to have been made pursuant to Section 6 hereof.
