ARTICLE III - ADMISSION TO PARTICIPATION.

3.1 INITIAL PARTICIPATION. Only Eligible Employees may participate in the Plan. Eligible Employees who are covered by a collective bargaining agreement may participate in the Plan unless the representative for such collectively bargained employees elects for such group of employees not to participate in the Plan. Any Eligible Employee may elect to be a Participant and may become a Participant by executing and filing with the Administrator a Purchase Agreement at such time in advance and on such forms as prescribed by the Administrator, or through telephone or other electronic arrangements as may be established by the Administrator. The effective date of an Eligible Employee’s participation shall be the Offering Date next following the date on which the Administrator receives from the Eligible Employee a properly filed Purchase Agreement; provided, however, that the Initial Offering Date may precede receipt of the Eligible Employee’s Purchase Agreement. Participation in the Plan will continue automatically from one Purchase Period to another unless notice is given pursuant to Section 3.2.

3.2 VOLUNTARY DISCONTINUANCE OF PARTICIPATION. Any Participant may voluntarily withdraw from the Plan by filing a Notice of Withdrawal with the Administrator at such time in advance and on such forms, or using such other procedures, as the Administrator may specify. Upon such withdrawal, there shall be paid to the Participant the amount, if any, standing to his credit in his Stock Purchase Account which has not yet been used to purchase Stock. The delivery of certificates representing the shares of Stock held for such Participant under the Plan shall be handled in the manner provided in Section 4.6.

3.3 INVOLUNTARY DISCONTINUANCE OF PARTICIPATION. If a Participant ceases to be an Eligible Employee other than by death, the entire amount, if any, standing to the Participant’s credit in his Stock Purchase Account shall be refunded to him. Notwithstanding the foregoing, should a Participant cease to be an Eligible Employee (as a result of the restrictions in Section 2.8(c)), such Participant may continue to participate only through the end of the Purchase Period during which he becomes ineligible to participate. The delivery of certificates representing the shares of Stock held for such Participant under the Plan shall be handled in the manner provided in Section 4.6.

3.4 READMISSION TO PARTICIPATION. Any Eligible Employee who has previously been a Participant, who has discontinued participation, and who wishes to be reinstated as a Participant may become a Participant after any waiting period determined by the Administrator and applied consistently to all Participants by executing and filing with the

-4-

Administrator, at such time in advance as the Administrator shall determine, a new Purchase Agreement on forms provided by the Administrator, or through telephone or other electronic arrangements as may be established by the Administrator. Reinstatement to Participant status shall be effective as of the Offering Date next following the later of (i) expiration of the waiting period, and (ii) the date on which the Administrator receives from the Eligible Employee the properly filed Purchase Agreement, provided that such Purchase Agreement is filed no later than the deadline in advance of such Offering Date as prescribed by the Administrator.

ARTICLE IV - STOCK PURCHASE.

4.1 RESERVATION OF SHARES. Except as provided in Section 5.2 hereof, the aggregate number of shares of Stock that may be purchased under the Plan shall not exceed Two Hundred Thousand (200,000) shares of Stock. Shares of Stock issued pursuant to the Plan may be either unissued shares of Stock, Stock held in treasury, or shares of Stock acquired in the market or directly from shareholders.

4.2 LIMITATION ON SHARES AVAILABLE. Subject to the other limitations set forth in the Plan, the maximum number of shares of Stock that may be purchased for each Participant on a Purchase Date is the lesser of (a) the number of whole and fractional shares of Stock that can be purchased by applying the full balance of his Stock Purchase Account to such purchase of shares at the Purchase Price (as hereinafter determined), (b) the number of shares of Stock that would not cause the Participant to exceed the limit of Section 2.8(a), or (c) an amount equal to 25% of the Participant’s expected Purchase Period Compensation divided by 95% of the Fair Market Value of the Stock on the Offering Date. A Participant’s expected Purchase Period Compensation shall be determined by multiplying his normal hourly or weekly rate of Compensation (as in effect on the last day prior to such Offering Date) by the number of regularly scheduled hours or weeks of work for such Participant during the Purchase Period. Any portion of a Participant’s Stock Purchase Account that cannot be applied by reason of the foregoing limitation shall remain in the Participant’s Stock Purchase Account for application to the purchase of Stock on the next Offering Date (unless withdrawn before such next Offering Date).

4.3 PURCHASE PRICE OF SHARES. The Purchase Price per share of Stock purchased for Participants pursuant to any Offering shall be the sum of (a) ninety-five percent (95%) of the Fair Market Value of such share of Stock on the Purchase Date on which such Offering expires and (b) any transfer, excise, or similar tax imposed on the transaction pursuant to which such share of Stock is purchased. If the Purchase Date with respect to the purchase of Stock is a day on which the stock is selling ex-dividend but is on or before the record date for such dividend, then for Plan purposes the Purchase Price per share will be increased by an amount equal to the dividend per share. In no event shall the Purchase Price be less than the par value of the Stock.

4.4 ESTABLISHMENT OF STOCK PURCHASE ACCOUNT. Each Participant shall authorize payroll deductions from Compensation for the purposes of funding his Stock Purchase Account. In the Purchase Agreement, each Participant shall authorize a deduction from each payment of his Compensation during a Purchase Period, which deduction shall be not more than twenty-five percent (25%) of the gross amount of such payment, subject to Section 4.5(b),

-5-

and not less than any minimum amount established by the Plan Administrator or its designee. If a Participant is employed by more than one Employer, such Participant can elect to have up to twenty-five percent (25%) of his Compensation from all Employers deducted from the payment of Compensation by a single Employer. The Administrator or its designee may require that any payroll deduction must be made in whole percentages (i.e., 1%, 2%, 3%, etc.) or in a dollar amount. In addition, the Administrator may allow, in its sole discretion and subject to such terms and procedural requirements as it may establish, for the delivery of payments by Participants directly to the Administrator or its designee; provided, however, that the total payroll deductions and direct cash payments may not exceed, in the aggregate for any calendar year, twenty-five percent (25%) of the total Compensation paid such Participant for the respective calendar year. A Participant may change the deduction to any permissible level for any subsequent Purchase Period by filing notice thereof at such time preceding the Offering Date on which such subsequent Purchase Period commences as the Administrator shall determine.

4.5 EXERCISE OF PURCHASE PRIVILEGE.

(a) Subject to the provisions of Section 4.2 above, on each Purchase Date there shall be purchased for the Participant at the Purchase Price the largest number of whole and fractional shares of Stock that can be purchased with the entire amount standing to the Participant’s credit in his Stock Purchase Account. A Participant may not sell the shares of Stock for a six-month period commencing on the Purchase Date for such shares of Stock, except in the event of the Participant’s termination of employment prior to such six-month date.

(b) Participant may not during any calendar year purchase shares of Stock having an aggregate Fair Market Value, determined at the time of each Offering Date during such calendar year, of more than $25,000, and (ii) all rights to purchase Stock offered on an Offering Date must be exercised within twenty-seven (27) months of such Offering Date.

4.6 SHARE OWNERSHIP; ISSUANCE OF CERTIFICATES

(a) The Stock purchased for a Participant on a Purchase Date shall, for all purposes, be deemed to have been issued and/or sold at the close of business on such Purchase Date. Prior to that time, none of the rights or privileges of a stockholder of the Company shall inure to the Participant with respect to such shares. All the shares of Stock purchased under the Plan shall be delivered by the Company in a manner as determined by the Administrator in accordance with Section 4.6(b).

(b) The Administrator, in its sole discretion, may determine the method for delivering shares of Stock by the Company, including, but not limited to, (i) by issuing or having delivered a certificate or certificates for the number of shares of Stock purchased for all Participants on a Purchase Date or during a calendar year to a member firm of the New York Stock Exchange which is also a member of the National Association of Securities Dealers, Inc., as selected by the Administrator from time to time, which shares shall be maintained by such member firm in separate accounts for each Participant, or (ii) by issuing or having delivered a certificate or certificates for the number of shares of Stock purchased for all Participants on a Purchase Date or during the calendar year to a bank or trust company or affiliate thereof, as

-6-

selected by the Administrator from time to time, which shares shall be maintained by such bank or trust company or affiliate in separate accounts for each Participant. In addition, the Administrator may periodically issue and deliver to the Participant a certificate for the number of whole shares of Stock purchased for such Participant on a Purchase Date or during such other time period as the Administrator may determine. Each Participant shall have full shareholder rights with respect to all shares of Stock purchased under the Plan, including, but not limited to, voting, dividend, and liquidation rights. Shares which are held in the name of the Company or its agent as the nominee for the Participant will be covered by proxies provided to such Participant by the Company or its agent. Unless provided otherwise, cash dividends paid on Stock issued under the Plan will be automatically reinvested. A Participant may withdraw certificates for his shares of Stock credited to his account at any time by a written request for such withdrawal delivered to the Administrator or its designee, or through telephone or other electronic arrangements as may be established by the Administrator. Upon any such request, the Company will promptly distribute such certificates to the requesting Participant. Any stock certificate distributed to a Participant may contain a legend requiring notification to the Company of any transfer or sale of the shares of Stock prior to the date two years after the Offering Date for the Offering under which the shares were purchased.

ARTICLE V - SPECIAL ADJUSTMENTS.

5.1 SHARES UNAVAILABLE. If, on any Exercise Date, the aggregate funds available for the purchase of Stock would purchase a number of shares in excess of the number of shares then available for purchase under the Plan, the following events shall occur:

(a) The number of shares that would otherwise be purchased for each Participant shall be proportionately reduced on the Purchase Date in order to eliminate such excess;

(b) The Plan shall automatically terminate immediately after the Purchase Date as of which the supply of available shares is exhausted; and

(c) Any amounts remaining in the respective Stock Purchase Accounts of the Participants shall be repaid to such Participants.

5.2 CHANGE IN CAPITALIZATION. The aggregate number of shares of Stock reserved for purchase under the Plan, as hereinabove provided, and the calculation of the Purchase Price per share shall be adjusted by the Administrator in an appropriate and equitable manner in the event of a Change in Capitalization (as hereinafter defined). For purposes of the Section 5.2, a “Change in Capitalization” means any increase or reduction in the number of Shares, or any change (including, but not limited to, a change in value) or exchange of Shares for a different number or kind of shares or other securities of the Company, by reason of a reclassification, recapitalization, merger, consolidation, reorganization, spin-off, split-up, issuance of warrants or rights or debentures, stock dividend, stock split or reverse stock split, extraordinary cash dividend, property dividend, combination or exchange of shares, repurchase of shares, public offering, private placement, change in corporate structure or otherwise.

5.3 EFFECT OF CERTAIN TRANSACTIONS. Subject to any required action by the stockholders, if the Company shall be the surviving or resulting corporation in any merger or consolidation, or if the Company shall be merged for the purpose of changing the jurisdiction of its incorporation, any Offering hereunder shall pertain to and apply to the shares of stock of the Company or the survivor. However, in the event of a dissolution or liquidation of the Company, or of a merger or consolidation in which the Company is not the surviving or resulting corporation, the Plan and any Offering hereunder shall terminate upon the effective date of such dissolution, liquidation, merger, or consolidation, and the balance then standing to the credit of each Participant in his Stock Purchase Account shall be returned to him.

6.4 COLLECTION OF TAXES. The Company shall be entitled to require any Participant to remit, through payroll withholding or otherwise, any tax that it determines it is so obligated to collect with respect to the issuance of Stock hereunder, or the subsequent sale or disposition of such Stock, and the Administrator shall institute such mechanisms as shall insure the collection of such taxes.

6.6 AMENDMENT OF THE PLAN. The Board may amend the Plan without the consent of stockholders or Participants, except that any such action shall be subject to the approval of the Company’s stockholders at or before the next annual meeting of stockholders for which the record date is set after such Board action if such stockholder approval is required by any federal or state law or regulation or the rules of any stock exchange or automated quotation
