Item 9. Undertakings. ------------ (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the 1934 Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the 1934 Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Subject to the provisions of the Plan, the Committee shall be authorized to interpret the Plan, to establish, amend and rescind any rules and regulations relating to the Plan, and to make all other determinations necessary or advisable for the administration of the Plan; provided, however, that the Committee shall have no discretion with respect to the eligibility or selection of Non-Employee Directors to receive awards under the Plan, the number of Shares subject to any such awards or the time at which any such awards are

to be granted. The Committee's interpretation of the Plan, and all actions taken and determinations made by the Committee pursuant to the powers vested in it hereunder, shall be conclusive and binding upon all parties concerned including the Company, its stockholders and persons granted awards under the Plan. The Committee may appoint a plan administrator to carry out the ministerial functions of the Plan, but the administrator shall have no other authority or powers of the Committee.

Participants. All active Non-Employee Directors shall be eligible to participate in the Plan. 6. Form of Payment of Retainer. (a) Annual Elections. On or before November 30 of each year (December 31, 1998 in the case of the first Plan Year), each Non-Employee Director shall file with the Plan Administrator an election form in substantially the form attached hereto as Exhibit A, or such other form as the Plan Administrator shall prescribe (the "Election Form"), in which such Non-Employee Director shall indicate his or her preference to receive some or all of his or her Retainer for the following Plan Year in the form of (i) cash, (ii) Common Stock, or (iii) Deferred Stock Rights. Such elections shall be made in increments of 25% of the Retainer. Individuals who are nominated to become Non-Employee Directors may make such election after such nomination but prior to the time they are elected to the Board. If a Non-Employee Director fails to timely file an Election Form for a Plan Year, then 100% of his or her Retainer for such Plan Year will be paid in cash. (b) Cash Payments. That portion of the Retainer to be paid in cash will be paid whenever such fees are payable, in accordance with the policies established by the Committee from time to time. (c) Grant Dates and Formula for Stock Grants. To the extent that a Non-Employee Director has elected to receive some or all of his or her Retainer in the form of Common Stock and has not elected to defer receipt of such shares pursuant to Section 6(e), shares of Common Stock shall be automatically granted to such Non-Employee Director on March 31, June 30, September 30 and December 31 of each Plan Year (each such date is hereinafter referred to as a "Quarterly Grant Date"). The total number of Shares included in each grant under this Section 6(c) shall be determined by (i) dividing the Stock Equivalent Amount earned by the Non-Employee Director during the three-month period immediately preceding the Quarterly Grant Date (the "Quarterly Service Period") by the Fair Market Value per Share on the Quarterly Grant Date, and (ii) and subtracting any Shares to be deferred pursuant to Section 6(e). Fractions will be rounded to the next highest Share.

(d) Termination of Service During Quarterly Service Period. In the event of termination of service on the Board by any Participant during a Quarterly Service Period, such Participant's award for the Quarterly Service Period shall be determined in accordance with Sections 6(b) based upon the Stock Equivalent Amount earned during such Quarterly Service Period through the date of termination of service, provided, that the grant date shall be the date of termination of service unless the grant has been deferred pursuant to Section 6(e). (e) Deferred Stock Rights. (i) Election to Defer. Each Participant will have the right to elect, in his or her Election Form delivered to the Plan Administrator prior to the commencement of each Plan Year, to defer until after the Participant's termination of service the grant of the Shares that would otherwise be granted to the Participant during the next ensuing Plan Year ("Deferred Stock Rights"). Pursuant to this Election Form, the Participant will elect whether all of the deferred grant will be (a) granted within 30 days after termination of service or (b) granted in approximately equal annual installments of Shares over a period of two to five years (as the Participant may elect) after the termination of service, each such annual grant to be made within 30 days after the anniversary of the termination of service. The deferral Election Form signed by the Participant prior to the Plan Year will be irrevocable except in case of Hardship (as defined in Section 6(f)) as determined in good faith by the Board pursuant to Section 6(f). No Shares will be issued until the grant date(s) so deferred (the "Deferred Grant Date") at which time the Company agrees to issue the Shares to the Participant. The Participant will have no rights as a stockholder with respect to the Deferred Stock Rights, and the Deferred Stock Rights will be unsecured. (ii) Deferred Dividend Account. If any dividends or other rights or distributions of any kind ("Distributions") are distributed to holders of Common Stock during the period from the applicable Quarterly Grant Date until the Deferred Grant Date (the "Deferral Period") but prior to the Participant's termination of service, an amount equal to the cash value of such Distributions on their distribution date, as such value is determined by the Committee, will be credited to a deferred dividend account for the Participant as follows: the account will be credited with the right to receive Shares having a Fair Market Value as of the date of the Distribution equal to the cash value of the Distribution. The Company will issue Shares equal to the cumulative total of rights to Shares in such account within 30 days after the Participant's termination of service. If a Distribution is distributed to holders of Common Stock after the Participant's termination of service but prior to the issuance in full of the deferred Shares, an amount equal to the cash value of such Distributions pertaining to any Shares still deferred shall be converted into Shares equivalent in value to the Distribution (based on the Fair Market Value as of the date of Distribution) and such Shares will be issued to the Participant as soon as practical after the date of the Distribution.

No right or interest in the Deferred Stock Rights or in the deferred dividend account shall be subject to liability for the debts, contracts or engagements of the Participant or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect; provided, however, that nothing in this Section 6(e) shall prevent transfers by will or by the applicable laws of descent and distribution. The Committee will have the right to adopt other regulations and procedures to govern deferral of grants of Shares. (f) Hardship. The Board may accelerate the distribution of all or a portion of a Participant's deferred grants of Shares on account of his or her Hardship, subject to the following requirements: (i) the value of such accelerated distribution shall not exceed the amount necessary to satisfy the Hardship, less the amount which can be satisfied from other resources which are reasonably available to the Participant, (ii) the denial of the Participant's request for a Hardship acceleration would result in severe financial hardship to the Participant, and (iii) the Participant has not received an accelerated distribution on account of Hardship within the 12- month period preceding the acceleration. For purposes of this Plan, "Hardship" of a Participant, as determined by the Board in its discretion on the basis of all relevant facts and circumstances and in accordance with the following nondiscriminatory and objective standards uniformly interpreted and consistently applied, shall mean a severe financial hardship to the Participant resulting from a sudden and unexpected illness or accident of the Participant or of his or her dependent, loss of the Participant's property due to casualty, or other extraordinary and unforeseeable circumstances arising as a result of events beyond the control of the Participant. A financial need shall not constitute a Hardship unless it is for at least $1,000,000 or the entire value of the principal amount of the Participant's deferred grants. 7. Prorated Grants. If on any Quarterly Grant Date, shares of Common Stock are not available under the Plan to grant to Non-Employee Directors the full amount of a grant contemplated by the Plan, then each such director shall receive an award equal to the number of shares of Common Stock then available under the Plan divided by the number of Non-Employee Directors entitled to a grant of shares on such date. Fractional shares shall be ignored and not granted. Any shortfall resulting from such proration shall be paid in the form of cash. 8. Withholding. Whenever the Company issues Shares under the Plan, the Company shall have the right to withhold from sums due the recipient, or to require the recipient to remit to the Company, any amount sufficient to satisfy any federal, state and/or local withholding tax requirements prior to the delivery of any certificate for such Shares. 9. Adjustments. (a) In the event that the Committee determines that any Distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization,

reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, or other similar corporate transaction or event, in the Committee's sole discretion, affects the Common Stock such that an adjustment is determined by the Committee to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to an award or awards hereunder, then the Committee shall, in such manner as it may deem equitable, adjust the number and type of Shares (or other securities or property) which may be granted under the Plan (including, but not limited to, adjustments of the maximum number and kind of securities which may be issued); provided, however, that to the extent required by the applicable exemptive conditions of Rule 16b-3, any such adjustment shall be subject to approval by the Board. (b) In the event of any corporate transaction or event described in paragraph (a) which results in Shares being exchanged for or converted into cash, securities or other property (including securities of another corporation), the Committee will have the right to terminate this Plan as of the date of the transaction or event, in which case all stock grants deferred under Section 6(e) shall become the right to receive such cash, securities or other property. (c) The number of Shares finally granted under this Plan shall always be rounded to the next highest whole Share. (d) Any decision of the Committee pursuant to the terms of this Section 9 shall be final, binding and conclusive upon the Participants, the Company and all other interested parties; provided, however, that to the extent required by the applicable exemptive conditions of Rule 16b-3, any such decision shall be subject to approval by the Board. 10. Amendment. The Committee may terminate or suspend the Plan at any time, without stockholder approval. The Committee may amend the Plan at any time and for any reason without stockholder approval; provided, however, that the Committee may condition any amendment on the approval of stockholders of the Company if such approval is necessary or deemed advisable with respect to tax, securities or other applicable laws, policies or regulations. No termination, modification or amendment of the Plan may, without the consent of a Participant, adversely affect a Participant's rights under an award granted prior thereto. 11. Indemnification. Each person who is or has been a member of the Committee or who otherwise participates in the administration or operation of this Plan shall be indemnified by the Company against, and held harmless from, any loss, cost, liability or expense that may be imposed upon or incurred by him or her in connection with or resulting from any claim, action, suit or proceeding in which such person may be involved by reason of any action taken or failure to act under the Plan and shall be fully reimbursed by the Company for any and all amounts paid by such person in satisfaction of judgment against him or her in any such action, suit or proceeding, provided he or she will give the Company an opportunity, by written notice to the Committee, to defend the same at the Company's own expense before he or she undertakes to

defend it on his or her own behalf. This right of indemnification shall not be exclusive of any other rights of indemnification. The Committee and the Board may rely upon any information furnished by the Company, its public accountants and other experts. No individual will have personal liability by reason of anything done or omitted to be done by the Company, the Committee or the Board in connection with the Plan. 12. Duration of the Plan. The Plan shall remain in effect until ten years from the Effective Date, unless terminated earlier by the Committee. 13. Expenses of the Plan. The expenses of administering the Plan shall be borne by the Company. 14. Effective Date. The Plan was originally adopted by the Board on November 23, 1998, and became effective upon the approval thereof by the stockholders of the Company on January 14, 1999 (the "Effective Date").

(b) Payroll deductions for a participant shall commence on the first payroll following the Enrollment Date and shall end on the last payroll in the Offering Period to which such authorization is applicable, unless sooner terminated by the participant as provided in paragraph 11. 6. Payroll Deductions. ------------------ (a) At the time a participant files his subscription agreement, he or she shall elect to have payroll deductions made on each payday during the Offering Period in an amount not less than one percent (1%) and not greater than twenty percent (20%) of the Compensation which he or she received on the payday immediately preceding the Enrollment Date, and the aggregate of such payroll deductions during the Offering Period shall not exceed twenty percent (20%) of his or her aggregate Compensation during said Offering Period. (b) All payroll deductions made by a participant shall be credited to his or her account under the Plan. A participant may not make any additional payments into such account. (c) A participant may discontinue his or her participation in the Plan as provided in paragraph 11, but may not otherwise change, their rate of payroll deductions during the Offering Period. A participant's subscription agreement shall remain in effect for successive Offering Periods unless revised as provided herein or terminated as provided in paragraph 11.

(d) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and paragraph 3(b) herein, a participant's payroll deductions may be decreased to 0% at such time during any Offering Period which is scheduled to end during the current calendar year that the aggregate of all payroll deductions accumulated with respect to such Offering Period and any other Offering Period ending within the same calendar year equal $21,250. Payroll deductions shall recommence at the rate provided in such participant's subscription agreement at the beginning of the first Offering Period which is scheduled to end in the following calendar year, unless terminated by the participant as provided in paragraph 11. 7. Grant of Option. --------------- (a) On the Enrollment Date of each Offering Period, each eligible Employee participating in such Offering Period shall be granted an option to purchase on each Exercise Date during such Offering Period up to a number of shares of the Company's Common Stock determined by dividing such Employee's payroll deductions accumulated prior to such Exercise Date and retained in the Participant's account as of the Exercise Date by the lower of (i) eighty-five percent (85%) of the fair market value of a share of the Company's Common Stock on the Enrollment Date or (ii) eighty-five percent (85%) of the fair market value of a share of the Company's Common Stock on the Exercise Date; provided that in no event shall an Employee be permitted to purchase during each Offering Period more than a number of shares determined by dividing $6,250 by the fair market value of a share of the Company's Common Stock on the Enrollment Date, and provided further that such purchase shall be subject to the limitations set forth in Section 3(b) and 13 hereof. Exercise of the option shall occur as provided in Section 8, unless the participant has withdrawn pursuant to Section 11, and shall expire on the last day of the Offering Period. Fair market value or a share of the Company's Common Stock shall be determined as provided in Section 7(b) herein. (b) The option price per share of the shares offered in a given Offering Period shall be the lower of: (i) 85% of the fair market value of a share of the Common Stock of the Company on the Enrollment Date; or (ii) 85% of the fair market value of a share of the Common Stock of the Company on the Exercise Date. The fair market value of the Company's Common Stock on a given date shall be determined by the Board in its discretion; provided, however, that where there is a public market for the Common Stock the fair market value per share shall be the average closing price for the preceding five (5) business days on the New York Stock Exchange (NYSE) on such date, as reported in The --- Wall Street Journal. - ------------------- 8. Exercise of Option. Unless a participant withdraws from the Plan as ------------------ provided in paragraph 11, his or her option for the purchase of shares will be exercised automatically on the Exercise Date of the Offering Period, and the maximum number of full shares subject to option will be purchased for him or her at the applicable option price with the accumulated payroll deductions in his account. The shares purchased upon exercise of an option hereunder shall be deemed to be transferred to the participant on the Exercise Date. During his or her lifetime, a participant's option to purchase shares hereunder is exercisable only by such participant. 9. Restriction on Transfer of Shares. Effective April 1, 1993, shares ---------------------------------- purchased upon exercise of a participant's option may not be transferred by the participant for a period of one (1) year from the Exercise Date. This transfer restriction shall be earlier terminated in the event of a

participant's permanent disability or death, or upon the involuntary transfer of the shares due to divorce, judicial declaration of insolvency or bankruptcy or other form of involuntary transfer. 10. Delivery. Prior to April 1, 1993, as promptly as practicable after -------- the Exercise Date of each Offering Period, the Company shall arrange the delivery to each participant of a certificate representing the full shares purchased upon exercise of the participant's option. Subsequent to April 1, 1993, immediately following the Exercise Date of each Offering Period, unless a participant requests the issuance of a certificate representing the participant's shares, the Company shall promptly record the participant's full shares in book entry form. Upon request from a participant, or upon the involuntary transfer of a participant's shares, the Company shall arrange for the delivery to the participant of a certificate representing the full shares purchased. Certificates issued upon a participant's request which are subject to the transfer restriction referred to in paragraph 9 shall bear a legend in a conspicuous place referencing the restriction. Any cash remaining to the credit of a participant's account under the Plan after a purchase by the participant of shares at the termination of each Offering Period, which is insufficient to purchase a full share of Common Stock of the Company, shall be returned to said participant or retained in the participant's account for the subsequent Offering Period, as determined by the Company as to all participants for a given Offering Period. 11. Withdrawal; Termination of Employment. ------------------------------------- (a) A participant may withdraw all but not less than all the payroll deductions credited to such participant's account under the Plan at any time prior to the Exercise Date of the Offering Period by giving written notice to the Company in the form of Exhibit B to this Plan. All of the participant's payroll deductions credited to his or her account will be paid to him or her promptly after receipt of the notice of withdrawal and the participant's option for the current Offering Period will be automatically terminated, and no further payroll deductions for the purchase of shares will be made during the Offering Period. If a participant withdraws from an Offering Period, payroll deductions will not resume at the beginning of the succeeding Offering Period unless the participant delivers to the Company a new subscription agreement as described in Section 5(a). (b) Upon termination of the participant's Continuous Status as an Employee prior to the Exercise Date of the Offering Period for any reason, including retirement or death, the payroll deductions credited to such participant's account will be returned to him or her or, in the case of his or her death, to the person or persons entitled thereto under paragraph 15, and such participant's option will be automatically terminated. (c) In the event an Employee fails to remain in Continuous Status as an Employee of the Company for at least twenty (20) hours per week during the Offering Period in which the Employee is a participant, he or she will be deemed to have elected to withdraw from the Plan and the payroll deductions credited to his or her account will be returned to him or her and the option terminated. (d) A participant's withdrawal from an Offering Period will not have any effect upon his or her eligibility to participate in a succeeding Offering Period or in any similar plan which may hereafter be adopted by the Company.

12. Interest. No interest shall accrue on the payroll deductions of a -------- participant in the Plan. 13. Stock. ----- (a) The maximum number of shares of the Company's Common Stock which shall be made available for sale under the Plan shall be 9,250,000 shares, subject to adjustment upon changes in capitalization of the Company as provided in paragraph 19. If the total number of shares which would otherwise be subject to options granted pursuant to Section 7(a) hereof on the Enrollment Date of an Offering Period exceeds the number of shares then available under the Plan (after deduction of all shares for which options have been exercised or are then outstanding), the Company shall make a pro rata allocation of the shares remaining available for option grant in as uniform a manner as shall be practicable and as it shall determine to be equitable. In such event, the Company shall give written notice of such reduction of the number of shares subject to the option to each participant affected thereby and shall similarly reduce the rate of payroll deductions, if necessary. (b) The participant will have no interest or voting right in shares covered by his or her option until such option has been exercised. (c) Shares to be delivered to a participant under the Plan will be registered in the name of the participant or in the name of the participant and his or her spouse. 14. Administration. The Plan shall be administered by the Board of the -------------- Company or a committee of members of the Board appointed by the Board. The administration, interpretation or application of the Plan by the Board or its committee shall be final, conclusive and binding upon all participants. Members of the Board who are eligible Employees are permitted to participate in the Plan, provided that: (a) Members of the Board who are eligible to participate in the Plan may not vote on any matter affecting the administration of the Plan or the grant of any option pursuant to the Plan. (b) If a Committee is established to administer the Plan, no member of the Board who is eligible to participate in the Plan may be a member of the Committee. 15. Designation of Beneficiary. -------------------------- (a) A participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the participant's account under the Plan in the event of such participant's death subsequent to the end of the Offering Period but prior to delivery to him of such shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any cash from the participant's account under the Plan in the event of such participant's death prior to the Exercise Date of the Offering Period.

(b) Such designation of beneficiary may be changed by the participant at any time by written notice. 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 shares and/or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 16. Transferability of Rights. Neither payroll deductions credited to a ------------------------- participant's account nor any rights with regard to the exercise of an option or to receive shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in paragraph 15 hereof) by the participant. Any such attempt at 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 paragraph 11. 17. 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. 18. Reports. Individual accounts will be maintained for each participant ------- in the Plan. Statements of account will be given to participating Employees; on no less than an annual basis, promptly following the Exercise Date, which statements will set forth the amounts of payroll deductions, the per share purchase price, the number of shares purchased and the remaining cash balance, if any. 19. Adjustments Upon Changes in Capitalization. Subject to any required ------------------------------------------ action by the shareholders of the Company, the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised and the number of shares of Common Stock which have been authorized for issuance under the Plan but have not yet been placed under option (collectively, the "Reserves"), as well as the price per share of Common Stock covered by each option under the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an option. In the event of the proposed dissolution or liquidation of the Company, the Offering Period will terminate immediately prior to the consummation of such proposed action, unless

otherwise provided by the Board. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each option under the Plan shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless the Board determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the participant shall have the right to exercise the option as to all of the optioned stock, including shares as to which the option would not otherwise be exercisable. If the Board makes an option fully exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Board shall notify the participant that the option shall be fully exercisable for a period of thirty (30) days from the date of such notice, and the option will terminate upon the expiration of such period. The Board may, if it so determines in the exercise of its sole discretion, also make provision for adjusting the Reserves, as well as the price per share of Common Stock covered by each outstanding option, in the event that the Company effects one or more reorganizations, recapitalizations, rights offerings or other increases or reductions of shares of its outstanding Common Stock, and in the event of the Company being consolidated with or merged into any other corporation. 20. Amendment or Termination. The Board of Directors of the Company may ------------------------ at any time terminate or amend the Plan. Except as provided in paragraph 19, no such termination can affect options previously granted, nor may an amendment make any change in any option theretofore granted which adversely affects the rights of any participant, nor may an amendment be made without prior approval of the shareholders of the Company (obtained in the manner described in paragraph 22) if such amendment would: (a) Increase the number of shares that may be issued under the Plan; (b) Change the designation of the employees (or class of employees) eligible for participation in the Plan; or (c) Materially increase the benefits which may accrue to participants under the Plan. (d) In the event that the Board determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Board may, in its discretion and, to the extent necessary or desirable, modify or amend the Plan by means of the following to reduce or eliminate such unfavorable accounting consequence including, but not limited to: (i) altering the option price per share for any Offering Period, including an Offering Period underway at the time of the change in Purchase Price including an alteration of the option price under paragraph 7(b) to 85% of the fair market value of a share of the Common Stock of the Company on the Exercise Date (without a lookback to the fair market value on the Enrollment Date); and (ii) shortening any Offering Period so that Offering Period ends on a

new Exercise Date, including an Offering Period underway at the time of the Board action. Such modifications or amendments shall not require stockholder approval or the consent of any Plan participants. 21. 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 in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 22. Shareholder Approval. Continuance of the Plan shall be subject to -------------------- approval by the shareholders of the Company within twelve months before or after the date the Plan is adopted. If such shareholder approval is obtained at a duly held shareholders' meeting, it may be obtained by the affirmative vote of the holders of a majority of the shares of the Company present or represented and entitled to vote thereon, which approval shall be: (a) (1) solicited substantially in accordance with Section 14(a) of the Securities Act of 1934, as amended (the "Act") and the rules and regulations promulgated thereunder, or (2) solicited after the Company has furnished in writing to the holders entitled to vote substantially the same information concerning the Plan as that which would be required by the rules and regulations in effect under Section 14(a) of the Act at the time such information is furnished; and (b) obtained at or prior to the first annual meeting of shareholders held subsequent to the first registration of Common Stock under Section 12 of the Act. In the case of approval by written consent, it must be obtained by the unanimous written consent of all shareholders of the Company, or by written consent of a smaller percentage of shareholders but only if the Board determines, on the basis of advice of the Company's legal counsel, that the written consent of such a smaller percentage of shareholders will comply with all applicable laws and will not adversely affect the qualifications of the Plan under Section 423 of the Code. 23. Conditions Upon Issuance of Shares. Shares shall not be issued with ---------------------------------- respect to an option unless the exercise of such option and the issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

24. Term of Plan. The Plan shall become effective upon the earlier to ------------ occur of its adoption by the Board of Directors or its approval by the shareholders of the Company as described in paragraph 22. It shall continue in effect for a term of twenty (20) years unless sooner terminated under paragraph 20.
