If an Option expires or terminates for any reason without having been exercised in full, the unpurchased -3- 4 shares subject to the Option shall become available for other Options granted under the Plan. The Company shall, at all times during which Options are outstanding, reserve and keep available shares of Stock sufficient to satisfy such Options, and shall pay all fees and expenses incurred by the Company in connection therewith.

An Employee who meets all of the foregoing requirements is referred to as an "Eligible Employee." 8. Terms and Conditions of Options. 8.1 General. All Options granted to Eligible Employees shall comply with the terms and conditions set forth in Sections 8.1 through 8.10. Subject to Sections 8.2(d) and 8.8, each such Option shall entitle the Optionee to purchase that number of shares calculated in accordance with Sections 8.1 through 8.10 or such lesser number or value of shares established by the Committee as an additional limitation on the maximum number of Option Shares available under an Option. 8.2 Membership Agreement/Payroll Deductions. (a) An Eligible Employee may elect to purchase shares of Stock under his or her Option during an Offering Period by completing a Membership Agreement and returning it to the personnel department of the Participating Employer at least ten business days prior to the beginning of such Offering Period. The Membership Agreement shall indicate the percentage of the Eligible Employee's Compensation (from 1% through 10%, in multiples of 1%) that the Eligible Employee elects to be withheld on pay dates occurring during the Offering Period. -4- 5 (b) After the commencement of the Offering Period, no Eligible Employee shall be permitted to change the percentage of Compensation elected to be withheld during that Offering Period. However, the Eligible Employee may elect to discontinue his or her payroll deductions at any time during an Offering Period and withdraw them by submitting a written request therefore to the personnel department of the Participating Employer no later than ten (10) business days prior to the last day of the Offering Period. The change will be effective as of the first pay date occurring as soon as practicable after the Eligible Employee's written request has been received. As soon as practicable following the last day of the Offering Period, he or she shall receive a distribution of the accumulated payroll deductions, without interest. (c) Any Membership Agreement in effect for an Offering Period shall remain in effect as to any subsequent Offering Period unless revoked by the submission of a written request to discontinue payroll deductions for that Offering Period or modified by submission of a new Membership Agreement, or until the Optionee's termination of Service for any reason. (d) Notwithstanding the provisions of this Section 8, an Eligible Employee may not be granted an Option if the Eligible Employee's rights to purchase Stock under all employee stock purchase plans (as defined in Section 423(b) of the Code) of the Company and its Related Corporations accrue at a rate which exceeds $25,000 of Fair Market Value of the Stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time. The accrual of rights to purchase Stock shall be determined in accordance with Section 423(b)(8) of the Code. (e) An Optionee may purchase Stock under the Plan only by payroll deduction. An Optionee may not make payroll deductions under the Plan for any period or periods after his or her termination of Service, even if he or she is then being paid salary continuation, severance benefits or other similar forms of compensation. 8.3 Purchase Price. The purchase price of Option Shares shall be shared by the Optionee and the Company. The Optionee's share with respect to Stock purchased on an Investment Date for an Offering Period shall be (i) the lesser of: (a) eighty-five percent (85%) of the Fair Market Value of the Stock on the Offering Commencement Date; or (b) (whichever is applicable) eighty-five percent (85%) of the Fair Market Value of the Stock on the Offering Termination Date, if the Stock is acquired from the Company; or (2) eighty-five percent (85%) of the actual purchase price for such Stock on the Investment Date if the Stock is, in fact, purchased on the New York Stock Exchange. The Company's share shall be the Fair Market Value or actual purchase price of the Stock (as the case may be) purchased for the Offering Period, less the Optionee's share, as described in the preceding sentence. 8.4 Exercise of Options. To the extent practicable, all of the Optionee's payroll deductions accumulated during the Offering Period will be applied to purchase Option Shares on the Investment Date. On such date, and provided the Optionee is in-Service on the last day of the Offering Period, the Optionee shall purchase the number of shares purchasable by his or her -5- 6 accumulated payroll deductions during the Offering Period, or, if less, the maximum number of shares subject to the Option as provided in Section 8.1, provided that: (a) If the total number of shares which all Optionees elect to purchase, together with any shares already purchased under the Plan, exceeds the total number of shares which may be purchased under the Plan pursuant to Section 6, the number of shares which each Optionee is permitted to purchase shall be decreased pro rata based on the Optionee's accumulated payroll deductions in relation to all accumulated payroll deductions currently being withheld under the Plan; and (b) If the number of shares purchasable includes a fraction, such number shall be adjusted to the next smaller whole number and the purchase price shall be adjusted accordingly. Accumulated payroll deductions, to the extent in excess of the aggregate purchase price of the shares purchased by the Optionee on an Investment Date or in excess of the $25,000 limit described in Section 8.2(d), shall be applied for the next Offering Period. At the request of the Optionee, following an Employee's withdrawal from the Plan, an Employee's termination of Service or as may be required by law, the excess payroll deductions shall be refunded to the Optionee, without interest, as soon as practicable. 8.5 Delivery of Stock. (a) Except as provided below, as soon as administratively practicable after the Investment Date, the Company shall deliver or cause to be delivered to the Optionee a certificate or certificates for the number of shares purchased by the Optionee for that Offering Period. A Stock certificate representing the number of shares purchased will be issued in the Optionee's name only, or if the Optionee so requests in writing, not later than the last day of the Offering Period, in the name of the Optionee and another person of legal age as joint tenants with rights of survivorship. If any law or applicable regulation of the Securities Exchange Commission or other body having jurisdiction shall require that the Company or the Optionee take any action in connection with the shares being purchased under the Option, delivery of the certificate or certificates for such shares shall be postponed until the necessary action shall have been completed, which action shall be taken by the Company at its own expense, without unreasonable delay. (b) Notwithstanding the foregoing, the Company may elect to hold for the benefit of the Optionee any shares otherwise to be delivered to the Optionee pursuant to this Section 8.5, or to deliver the same to such agents, trustees and fiduciaries for the benefit of the Optionee as the Company may select, for the period transfer of such shares is limited by this Plan (and thereafter, until the Optionee requests delivery of such stock in writing). In that event, the Optionee shall have all of the rights of a shareholder in the shares so held by the Company or its agent, except as limited by the restriction on transferability, from and after the issuance of the same and the Company or its agent shall adopt reasonable procedures to enable the Optionee to exercise such rights. In the event of the Optionee's death while any shares are so held, such shares shall be delivered to the -6- 7 Optionee's Beneficiary promptly following the Committee's receipt of evidence satisfactory to the Committee of the Optionee's death. (c) The Company or the Participating Employer shall pay all costs associated with issuing the Stock certificate or certificates described in subparagraph (a) above. (d) In lieu of issuing Stock certificates, the Committee may establish electronic book entry procedures (such as DWAC) to record an Optionee's Stock acquired under the Plan. Notwithstanding, the Optionee shall always have the right to request the issuance of a Stock certificate to evidence all or any number of the whole shares of Stock he or she has purchased under the Plan. 8.6 Restrictions on Transfer. (a) Options may not be assigned, transferred, pledged or otherwise disposed of. An Option may not be exercised by anyone other than the Optionee during the lifetime of the Optionee. (b) Stock acquired by exercise of an Option hereunder may not be assigned, transferred, pledged or other disposed of, except by will or under the laws of descent and distribution, until the date which is three (3) months after the last day of the Offering Period as of which such shares were acquired (or the date of the death of the Optionee, if earlier), but thereafter may be sold or otherwise transferred without restriction. The Optionee shall agree in the Membership Agreement to notify the Company of any transfer of the Shares within two years of the first day of the Offering Period of those Shares. The Company shall have the right to place a legend on all stock certificates instructing the transfer agent to notify the Company of any transfer of the shares. The Company shall also have the right to place a legend on certificates setting forth the restriction on transferability of such shares. 8.7 Expiration. Each Option shall expire at the close of business on the Investment Date or on such earlier date as may result from the operation of Section 8. 8.8 Termination of Employment of Optionee. If an Optionee ceases for any reason to be in-Service, whether due to death, retirement, voluntary severance, involuntary severance, transfer, or disaffiliation of a Related Corporation with the Company, his or her Option shall immediately expire, and the Optionee's accumulated payroll deductions shall be returned, without interest, as soon as practicable, to the Optionee or his or her Beneficiary, as the case may be, by the Participating Employer. For purposes of this Section 8.8, an Optionee shall be deemed to be in-Service throughout any leave of absence for military service, illness or other bona fide purpose which does not exceed the longer of ninety days or the period during which the Optionee's reemployment rights are guaranteed by statute or by contract. If the Optionee does not return to Service prior to the termination of such period, his or her Service shall be deemed to have ended on the ninety-first (91st) day of such leave of absence. Distributions upon death will be made as soon as administratively practicable after the Optionee's death upon presentation of satisfactory proof of death to the Participating Employer. -7- 8 8.9 Capital Changes Affecting the Stock. In the event that, during an Offering Period, a stock dividend is paid or becomes payable in respect of the Stock or there occurs a split-up or contraction in the number of shares of Stock, the number of shares for which the Option may thereafter be exercised and the price to be paid for each such share shall be proportionately adjusted. In the event that, after the commencement of the Offering Period, there occurs a reclassification or change of outstanding shares of Stock or a consolidation or merger of the Company with or into another corporation or a sale of conveyance, substantially as a whole, of the property of the Company, the Optionee shall be entitled on the last day of the Offering Period to receive shares of stock or other securities equivalent in kind and value to the shares of stock he or she would have held if he or she had exercised the Option in full immediately prior to such reclassification, change, consolidation, merger, sale or conveyance and had continued to hold such shares (together with all other shares and securities thereafter issued in respect thereof) until the last day of the Offering Period. In the event that there is to occur a recapitalization involving an increase in the par value of the Stock which would result in a par value exceeding the exercise price under an outstanding Option, the Company shall notify the Optionee of such proposed recapitalization immediately upon its being recommended by the Board of the Company's shareholders, after which the Optionee shall have the right to exercise his or her Option prior to such recapitalization; if the Optionee fails to exercise the Option prior to recapitalization, the exercise price under the Option shall be appropriately adjusted. In the event that, after the commencement of the Offering Period, there occurs a dissolution or liquidation of the Company, except pursuant to a transaction to which Section 424(a) of the Code applies, each Option shall terminate, but the Optionee shall have the right to exercise his or her Option prior to such dissolution or liquidation. 8.10 Return of Accumulated Payroll Deductions. In the event that the Optionee or his or her Beneficiary is entitled to the return of accumulated payroll deductions, whether by reason of an election to discontinue and withdraw payroll deductions, termination of employment, retirement, death, or, at the request of Optionee, in the event that accumulated payroll deductions exceed the price of shares purchased or exceed the $25,000 limit described in Section 8.2(d), such amount shall be returned by the Participating Employer to the Optionee or the Beneficiary, as the case may be, as soon as practicable following the end of the Offering Period in which the same were deducted. Accumulated payroll deductions held by the Participating Employer shall not bear interest nor shall the Participating Employer be obligated to segregate the same from any of its other assets. 9. No Enlargement of Employment Rights. Neither the establishment or continuation of the Plan, nor the grant of any Option hereunder, shall be deemed to give any employee the right to be retained in the employ of the Participating Employer, or any successor to either, or to interfere with the right of the Participating Employer or successor to discharge the employee at any time. 10. Tax Withholding. If, at any time, a Participating Employer is required, under applicable laws and regulations, to withhold, or to make any deduction of, any taxes or take any other action in connection any exercise of an Option or transfer of shares of Stock, the Participating Employer shall have the right to deduct from all amounts paid in cash any taxes -8- 9 required by law to be withheld therefrom, and in the case of shares of Stock, the Optionee or his or her estate or Beneficiary shall be required to pay the Participating Employer the amount of taxes required to be withheld, or, in lieu thereof, the Participating Employer shall have the right to retain, or sell without notice, a sufficient number of shares of Stock to cover the amount required to be withheld, or to make other arrangements with respect to withholding as it shall deem appropriate. 11. Participating Employer with Non-U.S. Residents. With respect to any Participating Employer which employs Eligible Employees who reside outside of the United States, and notwithstanding anything herein to the contrary, the Committee may in its sole discretion amend the terms of the Plan, or an Option granted under the Plan, in order to reflect the impact of local law and may, where appropriate, establish one or more sub-plans to reflect such amended provisions applicable to such Eligible Employees. 12. Governing Law. The Plan and all Options and actions taken thereunder shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts, without regard to the conflict of laws principles thereof. -9-
