The purpose of this Plan is to assist Qualified Employees in acquiring a stock ownership interest in the Company pursuant to a plan which is intended to qualify as an "employee stock purchase plan" under Section 423 of the Code. Under this Plan, Participants are deemed to have been granted options to purchase shares of Common Stock. Participants designate a certain amount of their 2 3 Base Pay to be set aside during the Offering Period for the purpose of purchasing Common Stock. At the end of the Offering Period, the Participants are deemed to have exercised their options using the funds set aside for them and the Company issues share certificates to them. The Plan is intended, among other things, to provide an additional incentive to Participants, through the ownership of Common Stock, to achieve business goals that would increase stock values and to remain in the employ of the Company or a Subsidiary. 3. STOCK SUBJECT TO THIS PLAN. Subject to the provisions of Section 10 hereof (relating to adjustments upon changes in capitalization), the total number of shares available under this Plan is 250,000 shares of Common Stock. Such shares may be authorized but unissued shares. 4. GRANT OF OPTIONS. (a) IN GENERAL. Commencing May 1, 1997 and continuing while this Plan remains in force, the Company will offer options to purchase shares of Common Stock under this Plan to all Participants. The options will be deemed to have been granted as of January 1 and July 1 (or, with respect to the 1997 calendar year, as of May 1 only) of each year (each, a "Grant Date"). The term of each option shall be six months (eight months for the 1997 calendar year), the last day of which shall be either June 30 or December 31, as applicable, (the "Exercise Date"). The number of shares subject to each option and deemed to be purchased by each Participant shall be the quotient, rounded down to the nearest whole number, of (i) the aggregate payroll deductions authorized by each Participant in accordance with Section 4(b) below made during the Offering Period, divided by (ii) the Option Price. The grant of options hereunder is subject to the approval of the Plan by the stockholders of the Company. If stockholder approval is not received by or before December 15, 1997, this Plan shall be deemed to be terminated and the options granted hereunder shall have no effect but instead shall be null and void. (b) ELECTION TO PARTICIPATE; PAYROLL DEDUCTION AUTHORIZATION. Except as provided in Section 4(d) below, a Qualified Employee may participate in this Plan only by means of payroll deductions. Each Qualified Employee who elects to participate in this Plan shall deliver to the Company, no later than 15 days next preceding a Grant Date (or April 10 for the 1997 calendar year), or the next business day following the 15th day preceding a grant date if such day is not a business day, a written payroll deduction authorization in a form approved by the Company pursuant to which he gives notice of his election to participate in this Plan as of the next following Grant Date, and whereby he designates a stated amount to be deducted from his Base Pay on each payday during the next Offering Period and credited to his bookkeeping account under this Plan ("Account"). The stated amount to be deducted from a Participant's Base Pay may not be less than $10.00 per pay period. The aggregate stated amount for any Offering Period may not exceed either of the following: (i) ten percent of the Participant's Base Pay during the Offering Period; or (ii) an amount which will result in noncompliance 3 4 with the $25,000 limitation stated in Section 4(c) below. Payroll deduction authorizations may not be changed during the Offering Period. In the event the number of shares of Common Stock subject to options during an Offering Period exceeds the number of shares then available under this Plan, the available shares shall be allocated among the Participants in proportion to the balance of their Accounts at the end of the Offering Period, and any amounts credited to their Accounts after giving effect to shares during purchased that Offering Period shall be refunded to the Participants. (c) $25,000 LIMITATION. No Participant shall be deemed to have been granted an option under this Plan which would permit his rights to purchase Common Stock under this Plan or any other employee stock purchase plan of the Company or any Subsidiary to accrue at a rate which exceeds $25,000 of Fair Market Value of Common Stock (determined as of the Grant Date of such option) for each calendar year such option is outstanding. For purposes of this subsection (c), the right to purchase Common Stock under an option accrues when the option (or any portion thereof) becomes exercisable, and the right to purchase Common Stock which has accrued during one Offering Period may not be carried over to any subsequent Offering Period. (d) LEAVES OF ABSENCE. During leaves of absence approved by the Company and meeting the requirements of Treasury Regulation Section 1.421-7(h)(2), a Participant may continue participation in this Plan by making cash payments to the Company on the Company's normal paydays equal to the reduction in his payroll deduction attributable to his leave. 5. EXERCISE OF OPTIONS. (a) IN GENERAL. On June 30 or December 31 of each Offering Period, as applicable, each Participant automatically and without any act on his part will be deemed to have exercised his option to the extent that the balance then credited to his Account is sufficient to purchase whole shares of Common Stock at the Option Price. The Company shall promptly refund to the Participant any balance remaining in his Account, without interest thereon, after giving effect to the purchase of such whole shares. (b) "OPTION PRICE" DEFINED. The Option Price per share to be paid by each Participant upon exercise of his option shall be an amount equal to 85% of the Fair Market Value of Common Stock on the Grant Date or on the Exercise Date, whichever amount is less. (c) DELIVERY OF SHARE CERTIFICATES. Subject to Section 5(d) below, the Company will deliver to each Participant a certificate issued in the Participant's name for the number of shares with respect to which his option was exercised. The Company will deliver the certificate as soon as practicable following the Exercise Date. 4 5 (d) GOVERNMENT REGULATIONS. This Plan, the granting of options under this Plan and the issuance of Common Stock pursuant hereto are subject to all applicable federal and state laws, rules and regulations and to such approvals by any regulatory or governmental agency which may, in the opinion of counsel for the Company, be necessary or advisable in connection therewith. Without limiting the generality of the foregoing, no options may be granted under this Plan, and no shares may be issued by the Company, unless and until, in each such case, all legal requirements applicable to the grant or issuance have, in the opinion of counsel to the Company, been complied with. In connection with the issuance of Common Stock hereunder, the Participant shall, if requested by the Company, give assurances satisfactory to counsel to the Company in respect of such matters as the Company may deem desirable to assure compliance with all applicable legal requirements. 6. WITHDRAWAL FROM THIS PLAN. (a) IN GENERAL. Any Participant may completely withdraw from this Plan at any time. A Participant who desires to withdraw from this Plan must deliver to the Company a notice of withdrawal in a form approved by the Company. Promptly following the time when the notice of withdrawal is delivered, the Company will refund to the Participant the amount of the balance of his Account, without interest thereon, and the Participant's payroll deduction authorization, interest in this Plan and option under this Plan shall thereupon terminate. (b) ELIGIBILITY FOLLOWING WITHDRAWAL. A Participant who has withdrawn from this Plan shall again be eligible to participate in this Plan upon expiration of the Offering Period during which the Participant withdrew. 7. TERMINATION OF EMPLOYMENT FOR ANY REASON. If the employment of a Participant by the Company or a Subsidiary terminates during an Offering Period for any reason, his participation in this Plan automatically and without any act on his part shall terminate as of the date of the termination of the Participant's employment. The Company promptly will refund to the Participant the amount of the balance of his Account, without interest thereon, and thereupon his interest in and option under this Plan shall terminate. Nothing in this Plan shall prevent the Company or any Subsidiary from terminating any Participant's employment. 8. RESTRICTION UPON ASSIGNMENT. An option granted under this Plan shall not be transferable and is exercisable during the Participant's lifetime only by the Participant. The Company will not recognize any assignment or purported assignment by a Participant of his option or of any rights under his option or under this Plan. 9. NO RIGHTS AS STOCKHOLDER. With respect to shares of Common Stock subject to an option, a Participant shall not be deemed to be a stockholder and shall not have any of the rights or privileges of a stockholder until a certificate for shares of Common Stock has been issued to the Participant following the exercise of his option. 5 6 10. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. If the outstanding shares of Common Stock are increased, decreased or changed into, or exchange for, a different number or kind of shares or securities of the Company through a reorganization or merger in which the Company is the surviving entity, or through a combination, recapitalization, reclassification, stock split, stock dividend, stock consolidation or otherwise, an appropriate adjustment shall be made in the number and kind of shares that may be issued under this Plan. Upon the dissolution or liquidation of the Company, or upon a reorganization, merger, or consolidation of the Company with one or more corporations as a result of which the Company is not the surviving corporation, or upon a sale of all or substantially all of the property of the Company to another corporation, this Plan shall terminate, and any outstanding options shall terminate and the Company thereupon will promptly refund the balance of the Participants' Accounts to the Participants, without interest thereon, unless (i) the Committee shall determine, in its sole and absolute discretion, that any or all options under this Plan shall accelerate and become immediately exercisable or (ii) provision shall be made in connection with such transaction for the assumption of options theretofore granted hereunder, or the substitution for such options or new options covering the stock of a successor employer corporation, or a parent or subsidiary thereof, with appropriate adjustments as to number and kind of shares and prices. If the Committee determines to accelerate any or all of the options, the acceleration date designated by the Committee shall be deemed to be the Exercise Date for the purpose of computing the option price of the accelerated option. In so adjusting Common Stock to reflect such changes, or in determining that no such adjustment is necessary, the Committee may rely upon the advice of independent counsel and accountants of the Company, and the determination of the Committee shall be conclusive. No fractional shares of stock shall be issued under this Plan on account of any such adjustment. 11. USE OF FUNDS; NO INTEREST PAID. All amounts withheld from Participants' paychecks hereunder and credited to their Accounts will be included in the general funds of the Company free of any trust or other restriction and may be used by the Company for any corporate purpose. Under no circumstances shall interest on such amounts be paid to any Participant or credited to his Account. 12. AMENDMENT OF THIS PLAN. The Board may amend, suspend or terminate this Plan at any time and from time to time; provided, however, that, if any amendment would (i) materially increase the benefits accruing to Participants under this Plan, (ii) materially increase the aggregate number of shares of Common Stock that may be issued under this Plan, or (iii) materially modify the requirements as to eligibility for participation in this Plan, then to the extent required under Section 423 of the Code or any other applicable law, or deemed necessary or advisable by the Board, such amendment shall be subject to stockholder approval. Notwithstanding anything else 6 7 contained herein, the Board shall have the right to designate from time to time the Subsidiaries whose employees may be eligible to participate in the Plan and such designations shall not constitute an amendment to the Plan requiring stockholder approval in accordance with Treasury Regulation Section 1.423-2(c)(4). 13. ADMINISTRATION BY COMMITTEE; RULES AND REGULATIONS. This Plan shall be administered by a committee composed of not less than two directors of the Company (the "Committee"), each of whom shall be a "non-employee" as such term is defined in Rule 16b-3(b)(3) under the Exchange Act or any successor provision of the Exchange Act so that the Committee members are qualified to administer this Plan under such provision. Each member shall serve for a term commencing on a date specified by the Board and continuing until he dies or resigns or is removed from office by the Board. The Committee shall have the power to make, amend and repeal rules and regulations for the interpretation and administration of this Plan consistent with the qualification of this Plan under Section 423 of the Code and consistent with Rule 16b-3 under the Exchange Act. 14. TERM; APPROVAL BY STOCKHOLDERS. No option may be granted during any period of suspension nor after termination of this Plan, and in no event may any option be granted under this Plan after the date on which all of the Common Stock available under this Plan has been purchased. This plan shall be submitted for the approval of the Company's stockholders within 12 months after the date of the Board's initial adoption of this Plan and shall be effective upon its approval by the stockholders; provided, however, effectiveness of this Plan shall be conditioned upon consummation of a public offering of the Company's Common Stock on or before March 15, 1997. 15. EFFECT UPON OTHER PLANS. The adoption of this Plan shall not affect any other compensation or incentive plans in effect for the Company or any Subsidiary. Nothing in this Plan shall be construed to limit the right of the Company or any Subsidiary (a) to establish any other forms of incentives or compensation for employees of the Company or any Subsidiary or (b) to grant or assume options otherwise than under this Plan in connection with any proper corporate purpose. 16. HEADINGS. Headings are provided herein for convenience only and shall not serve as a basis for interpretation or construction of this Plan. 17. GOVERNING LAW. This Plan shall be governed by, and construed and enforced in accordance with, the laws of the State of Connecticut. If any provisions shall be held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions of this Plan shall continue to be fully effective. 7
