Participation in any one or more of the Offerings shall neither limit nor require participation in any other Offering. SECTION 5. PARTICIPATION Any eligible employee may become a participant in an Offering by completing a payroll deduction authorization form provided by the Company and filing it with the Designated Officer of the Company at least five business days prior to the applicable Offering Commencement Date, as determined by the Committee pursuant to Section 4. A participant who obtains shares of Common Stock in one Offering will be deemed to have elected to participate in each subsequent Offering, provided such participant is eligible to participate in the subsequent Offering and has not specifically elected not to participate in the Offering. Such participant will also be deemed to have authorized the same payroll deductions under Section 6 for each such subsequent Offering as in the immediately preceding Offering; provided, however, that, during the enrollment period prior to each new Offering, the participant may elect to change such participant's payroll deductions by submitting a new payroll deduction authorization form. SECTION 6. PAYROLL DEDUCTIONS (a) At the time a participant files a payroll deduction authorization form with respect to an Offering, the participant shall elect to have deductions made from the participant's pay on each payday during the Offering in which he or she is a participant, at a specified percentage of the participant's Compensation as determined on the applicable Offering Commencement Date. The specified percentage shall be in increments of one percent up to a maximum percentage of six percent. -2- (b) Payroll deductions for a participant shall commence on the Offering Commencement Date when the applicable authorization for a payroll deduction becomes effective and, subject to the last sentence of Section 6, shall end on the Offering Termination Date of the Offering to which such authorization is applicable, unless sooner terminated by the participant as provided in Section 9. (c) All payroll deductions made for a participant shall be credited to the participant's account under the Plan. A participant may not make any separate cash payment into such account. SECTION 7. GRANTING OF OPTION (a) Except as provided in Section 3(b)(ii), on the Offering Commencement Date of each Offering, a participating employee shall be deemed to have been granted an option to purchase a maximum number of shares of the Common Stock determined as follows: (i) 85% of the market value per share of the Common Stock (determined as provided in Section 7(b)(i)) on the applicable Offering Commencement Date shall be divided into the percentage of the employee's Compensation which the employee has elected to have withheld (multiplied by the employee's Compensation over the Offering Period), multiplied by (ii) two. (b) The option price of the Common Stock purchased with payroll deductions made during each such Offering for a participant therein shall be the lower of: (i) 85% of the average of the bid and asked prices as reported by Nasdaq Stock Market, Inc. in The Wall Street Journal, or, if the Common Stock is designated as a Nasdaq National Market security, the last trading price of the Common Stock as reported on the Nasdaq National Market in The Wall Street Journal, or, if the Common Stock is listed on an exchange, the closing price of the Common Stock on the exchange on the Offering Commencement Date applicable to such Offering (or on the next regular business date on which shares of the Common Stock shall be traded, in the event that no shares of the Common Stock have been traded on the Offering Commencement Date); or if the Common Stock is not quoted by Nasdaq Stock Market, Inc., not designated as a Nasdaq National Market security and not listed on an exchange, 85% of the fair market value on the Offering Commencement Date as determined by the Committee; and (ii) 85% of the average of the bid and asked prices as reported by Nasdaq Stock Market, Inc. in The Wall Street Journal, or, if the Common Stock is designated as a Nasdaq National Market security, the last trading price of the Common Stock as reported by the Nasdaq National Market in The Wall Street Journal, or, if the Common Stock is listed on an exchange, the closing price of the Common Stock on the exchange on the Offering Termination Date applicable to such Offering (or on the next regular business date on which shares of the Common Stock shall be traded, in the event that no shares of the Common Stock shall have been traded on the Offering Termination Date); or if the Common Stock is not quoted by Nasdaq Stock Market, Inc., not designated as a Nasdaq National Market security and not listed on an exchange, 85% of the fair market value on the Offering Termination Date as determined by the Committee. SECTION 8. EXERCISE OF OPTION (a) Unless a participant gives written notice to the Designated Officer as hereinafter provided, the participant's option for the purchase of Common Stock with payroll deductions made during any Offering will be deemed to have been exercised automatically on the Offering Termination Date applicable to such Offering for the purchase of the number of full shares of Common Stock which the accumulated payroll deductions in the participant's account at that time will purchase at the applicable option price (but not in excess of the -3- number of shares for which options have been granted to the participant pursuant to Section 7(a)), and any excess in the participant's account at that time will be returned to the participant, without interest. (b) Fractional shares will not be issued under the Plan and any accumulated payroll deductions that would have been used to purchase fractional shares shall be automatically carried forward to the next Offering unless the participant elects, by written notice to the Designated Officer, to have the excess cash returned to the participant. SECTION 9. WITHDRAWAL AND TERMINATION (a) Prior to the Offering Termination Date for an Offering, any participant may withdraw the payroll deductions credited to the participant's account for such Offering under the Plan by giving written notice to the Designated Officer. All of the participant's payroll deductions credited to such account will be paid to the participant promptly after receipt of notice of withdrawal, without interest, and no future payroll deductions will be made from the participant's pay during such Offering. The Company will treat any attempt to borrow by a participant on the security of accumulated payroll deductions as an election to withdraw such deductions. (b) A participant's election not to participate in, or withdrawal from, any Offering will not have any effect upon the participant's eligibility to participate in any succeeding Offering or in any similar plan which may hereafter be adopted by the Company. (c) Upon termination of the participant's employment for any reason, including retirement but excluding death, the payroll deductions credited to the participant's account will be returned to the participant, or, in the case of the participant's death, to the person or persons entitled thereto under Section 13. (d) Upon termination of the participant's employment because of death, the participant's beneficiary (as designated pursuant to Section 13) shall have the right to elect, by written notice given to the Designated Officer prior to the expiration of a period of ninety days commencing with the date of the death of the participant, either: (i) to withdraw all of the payroll deductions credited to the participant's account under the Plan; or (ii) to exercise the participant's option for the purchase of stock on the Offering Termination Date next following the date of the participant's death for the purchase of the number of full shares which the accumulated payroll deductions in the participant's account at the date of the participant's death will purchase at the applicable option price (subject to the limitation contained in Section 7(a)), and any excess in such account will be returned to said beneficiary. In the event that no such written notice of election shall be duly received by the office of the Designated Officer, the beneficiary shall automatically be deemed to have elected to withdraw the payroll deductions credited to the participant's account at the date of the participant's death and the same will be paid promptly to said beneficiary. SECTION 10. INTEREST No interest will be paid or allowed on any money paid into the Plan or credited to the account of any participating employee. -4- SECTION 11. STOCK (a) The maximum number of shares of Common Stock available for issuance and purchase by employees under the Plan (including shares issued prior to the amendment and restatement hereof on December 16, 1998), subject to adjustment upon changes in capitalization of the Company as provided in Section 16, shall be 200,000 shares. If the total number of shares for which options are exercised on any Offering Termination Date in accordance with Section 8 exceeds the number of shares that remain available for issuance and purchase by employees under the Plan, the Company shall make a pro rata allocation of the shares available for delivery and distribution in an equitable manner, with the balances of payroll deductions credited to the account of each participant under the Plan returned to each participant. (b) The participant will have no interest in the stock covered by the participant's option until such option has been exercised. SECTION 12. ADMINISTRATION The Plan shall be administered by the Committee. The interpretation and construction of any provision of the Plan and adoption of rules and regulations for administering the Plan shall be made by the Committee. Determinations made by the Committee with respect to any matter or provision contained in the Plan shall be final, conclusive and binding upon the Company and upon all participants, their heirs or legal representatives. Any rule or regulation adopted by the Committee shall remain in full force and effect unless and until altered, amended or repealed by the Committee. SECTION 13. DESIGNATION OF BENEFICIARY A participant shall file with the Designated Officer a written designation of a beneficiary who is to receive any Common Stock and/or cash under the Plan. Such designation of beneficiary may be changed by the participant at any time by written notice. Upon the death of a participant and upon receipt by the Company of proof of the identity and existence of a beneficiary validly designated by the participant under the Plan, the Company shall deliver such Common Stock and/or cash to such beneficiary. In the event of the death of a participant and 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 Common Stock and/or cash to the executor or administrator of the estate of the participant. No beneficiary shall, prior to the death of the participant by whom he or she has been designated, acquire any interest in the Common Stock and/or cash credited to the participant under the Plan. SECTION 14. TRANSFERABILITY Neither payroll deductions credited to a participant's account nor any rights with regard to the exercise of an option or to receive Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way by the participant other than by will or the laws of descent and distribution. Any such attempted assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election to withdraw funds in accordance with Section 9(a). SECTION 15. USE OF FUNDS All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. -5- SECTION 16. EFFECT OF CHANGES OF COMMON STOCK If at any time after the effective date of the Plan the Company shall subdivide or reclassify the Common Stock which has been or may be optioned under the Plan, or shall declare thereon any dividend payable in shares of such Common Stock, or shall take any other action of a similar nature affecting such Common Stock, then the number and class of shares of Common Stock which may thereafter be optioned (in the aggregate and to any participant) shall be adjusted accordingly and in the case of each option outstanding at the time of any such action, the number and class of shares which may thereafter be purchased pursuant to such option and the option price per share shall be adjusted to such extent as may be determined by the Committee, following consultation with the Company's independent public accountants and counsel, to be necessary to preserve the rights of the holder of such option. SECTION 17. AMENDMENT OR TERMINATION The Board may at any time terminate or amend the Plan. No such termination shall affect options previously granted, nor may an amendment make any change in any option theretofore granted which would adversely affect the rights of any participant holding options under the Plan. SECTION 18. NOTICES All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received by the Designated Officer. SECTION 19. MERGER OR CONSOLIDATION If the Company shall at any time merge into or consolidate with another corporation, the holder of each option then outstanding will thereafter be entitled to receive at the next Offering Termination Date, upon the exercise of such option and for each share as to which such option shall be exercised, the securities or property which a holder of one share of the Common Stock was entitled to upon and at the time of such merger or consolidation. In accordance with this Section and Section 16, the Committee shall determine the kind and amount of such securities or property which such holder of an option shall be entitled to receive. A sale of all or substantially all of the assets of the Company shall be deemed a merger or consolidation for the foregoing purposes. SECTION 20. APPROVAL OF STOCKHOLDERS The Plan is subject to the approval of the stockholders of the Company by written consent or at their next annual meeting or at any special meeting of the stockholders for which one of the purposes of such a special meeting shall be to act upon the Plan. SECTION 21. GOVERNMENTAL AND OTHER REGULATIONS The Plan, and the grant and exercise of the rights to purchase shares hereunder, and the Company's obligation to sell and deliver shares upon the exercise of rights to purchase shares, shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may, in the opinion of counsel for the Company, be required. The Plan shall be governed by, and construed and enforced in accordance with, the provisions of Sections 421, 423 and 424 of the Code and the substantive laws of the State of New Hampshire. In the event of any inconsistency between such provisions of the Code and any such laws, the provisions of the Code shall govern to the extent necessary -6- to preserve the favorable federal income tax treatment afforded employee stock purchase plans under Section 423 of the Code. -7-
