The Committee shall have the power to change the duration and/or the frequency of Offering Periods with respect to future Offering Periods if such change is announced at least five (5) days prior to the scheduled beginning of the first Offering Period to be affected, subject to compliance with Applicable Laws.

5.                                       Participation.

(a)                                  An eligible Employee may become a Participant in the Plan by completing a subscription agreement and any other required documents (“Enrollment Documents”) provided by the Company and submitting them to the Company or, as applicable, the stock brokerage or other financial services firm designated by the Company (“Designated Broker”) within the period set by the Committee with respect to a given Offering Period. The Enrollment Documents and their submission may be electronic, as directed by the Company.

(b)                                 Payroll deductions shall commence on the date of the first paycheck paid on or after the Offering Date and shall end on the date of the last paycheck paid on or prior to the Purchase Date of the Offering Period to which the Enrollment Documents are applicable, unless sooner terminated by the Participant as provided in Section 10.

(c)                                  Once an eligible Employee becomes a Participant in the Plan, he or she will automatically participate in all subsequent Offering Periods at the same Contribution rate, unless he or she (i) submits new Enrollment Documents or (ii) withdraws from participation in the Plan as provided in Section 10 of the Plan.

6.                                       Method of Payment of Contributions.

(a)                                  A Participant shall elect to have payroll deductions made on each payday during the Offering Period at the rate of any whole percentage of the Participant’s Compensation not less than one percent (1%) and not more than ten percent (10%) (or such greater percentage as the Committee may establish from time to time before an Offering Date). All Contributions made by a Participant will be credited to a bookkeeping account in his or her name under the Plan. A Participant may not make any additional payments into the Plan. Notwithstanding the foregoing, in locations in which Applicable Law prohibits payroll deductions, an eligible Employee may elect to participate through contributions to his or her account under the Plan in a form acceptable to the Committee, and such Employees shall be deemed to be participating in a sub-plan, unless the Committee otherwise expressly provides that such Employees shall be treated as participating in the Plan.

(b)                                 The Committee may establish rules pertaining to the changes to the rate of a Participant’s Contributions, limiting the frequency with which Participants may change his or

5

her rate of participation, the timing of the elections for such changes, and whether or not changes may effectuate an increase in Contributions or only a decrease in Contributions. A Participant may change his or her rate of Contributions with respect to current or future Offering Periods by filing new Enrollment Documents at such times and on such terms as specified by the Committee.

(c)                                  To the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) herein, a Participant’s payroll deductions may be decreased by the Company to 0% during any Offering Period scheduled to end during the current calendar year. Payroll deductions shall re-commence at the rate provided in such Participant’s then-effective Enrollment Documents at the beginning of the first Offering Period that is scheduled to end in the following calendar year. In addition, a Participant’s payroll deductions may be decreased by the Company to 0% at any time during an Offering Period in order to avoid unnecessary payroll contributions as a result of application of the maximum share limit set forth in Section 8, in which case payroll deductions shall re-commence at the rate provided in such Participant’s then-effective Enrollment Documents at the beginning of the next Offering Period.

7.                                       Grant of Option. On the Offering Date of each Offering Period, each eligible Employee shall be granted an option to purchase on each Purchase Date a number of Shares of the Company’s Common Stock determined by dividing the accumulated Contributions credited to the Participant’s account as of the Purchase Date by the applicable Purchase Price. An option will expire upon the earliest to occur of (i) the failure of a newly eligible Employee to complete and submit the Enrollment Documents by the date determined by the Committee with respect to that Offering Period, (ii) the termination of a Participant’s participation in the Plan, (iii) the exercise of the option on the Purchase Date or (iv) the termination of the Offering Period as provided in the Plan.

8.                                       Exercise of Option.

(a)                                  Unless a Participant withdraws from the Plan as provided in Section 10, and except as otherwise provided in Sections 7, 18 or 19, the Participant’s option for the purchase of Shares will be exercised automatically on the Purchase Date of the Offering Period for the purchase of that number of whole Shares that can be purchased under the option with the accumulated Contributions credited to the Participant’s account at the applicable Purchase Price. Notwithstanding the foregoing, and in addition to any other limitations set forth in the Plan and under Applicable Law, the maximum number of Shares a Participant may purchase during each Offering Period shall be 1,000 Shares and the maximum number of Shares that all Participant may purchase in the aggregate during each Offering Period shall be 100,000 Shares, in each case subject to any adjustment pursuant to Section 18 below. The Company shall retain the full amount of Contributions used to purchase Common Stock as payment for the Common Stock.

(b)                                 For tax purposes, the Shares purchased upon exercise of an option hereunder shall be deemed to be sold to the Participant on the Purchase Date. The Company or its designee may make such provisions and take such action as it deems necessary or appropriate for the withholding of taxes and/or social insurance as required by Applicable Law. Each Participant is responsible for the payment of all individual tax liabilities arising under the Plan, including with respect to the sale or other disposition of Shares acquired under the Plan.

6

9.                                       Delivery.

(a)                                  The Company will deliver Shares purchased under the Plan (or a record thereof) as promptly as possible. The Committee may permit or require that Shares purchased under the Plan be deposited directly with the Designated Broker, and the Committee may utilize electronic or automated methods of Share transfer. The Committee may require that Shares be retained with the Designated Broker for a designated period of time and/or may establish other procedures to permit tracking of “disqualifying dispositions” of such Shares. A “disqualifying disposition” is any sale or other disposition which is made within two years after the Offering Date or within one year after the Purchase Date. A “qualifying disposition” will occur if the sale or other disposition of the Shares is made after the Shares have been held for more than two years after the Offering Date and more than one year after the Purchase Date. Participants are urged to consult their personal tax advisors regarding the specific U.S. federal, state, local and foreign income and other tax consequences applicable to dispositions.

(b)                                 The Committee may in its discretion direct the Company to retain in a Participant’s account for the subsequent Offering Period any payroll deductions which are not sufficient to purchase a whole Share of Common Stock or return such amount to the Participant. Any other amounts left over in a Participant’s account after a Purchase Date shall be returned to the Participant.

(c)                                  No Participant shall have any voting, dividend, or other stockholder rights with respect to Shares subject to any option granted under the Plan until the Shares subject to the option have been purchased and delivered to the Participant as provided in this Section 9.

10.                                 Voluntary Withdrawal; Termination of Employment.

(a)                                  A Participant may terminate his or her participation in the Plan and withdraw all of the Contributions credited to his or her account under the Plan prior to a Purchase Date by submitting a completed “Notice of Withdrawal” form to the Company (or, as applicable, the Designated Broker). As soon as practicable following the Company’s receipt of the Notice of Withdrawal, all of the Participant’s Contributions credited to his or her account will be returned without any interest thereon, and no further Contributions for the purchase of Shares will be made during the Offering Period. The Committee may establish rules (i) pertaining to the timing of withdrawals, (ii) limiting the frequency with which Participants may withdraw and re-enroll and (iii) imposing a waiting period on Participants wishing to re-enroll following withdrawal.

(b)                                 Upon termination of the Participant’s Continuous Status as an Employee prior to the Purchase Date of an Offering Period for any reason, the Contributions credited to his or her account will be returned to him or her or, in the case of his or her death, to the person or persons entitled thereto, and his or her option will be automatically terminated.

(c)                                  The Committee may establish rules regarding when leaves of absence or changes of employment status will be considered to be a termination of employment, and the Committee may establish termination-of-employment procedures for this Plan that are independent of similar rules established under other benefit plans of the Company and its

7

Designated Subsidiaries; provided that such procedures are not in conflict with the requirements of Section 423 of the Code.

11.                                 Interest. No interest shall accrue on the Contributions of a Participant in the Plan.

12.                                 Stock.

(a)                                  Subject to adjustment as provided in Section 18, the maximum number of Shares that may be made available for sale and which may be issued under the Plan shall be 4,000,000 Shares. The Shares may consist, in whole or in part, of unissued Shares, treasury Shares, or Shares purchased by the Company on the open market. The issuance of Shares pursuant to the Plan shall reduce the total number of Shares that may be made available for sale and which may be issued under the Plan.

(b)                                 If the Committee determines that, on a given Purchase Date, the number of Shares with respect to which options are to be exercised may exceed (1) the number of Shares of Common Stock that were available for sale under the Plan as of the Offering Date, or (2) the number of Shares available for sale under the Plan with respect to that Offering Period, the Committee may in its sole discretion provide for a pro rata allocation of the Shares of Common Stock available for purchase in that Offering Period in as uniform a manner as shall be practicable and equitable among all Participants in that Offering Period and either (i) continue the Plan or (ii) terminate the Plan pursuant to Section 19 below.

13.                                 Administration.

(a)                                  The Committee will have the authority and responsibility for the day-to-day administration of the Plan as well as the authority and responsibility specifically provided in this Plan, in addition to any other duties, responsibilities and authority delegated to the Committee by the Board. The Committee may delegate to one or more individuals the day-to-day administration of the Plan. The Committee shall have full power and authority to (i) adopt, amend and rescind any Plan rules which it deems desirable and appropriate for the proper administration of the Plan, (ii) construe and interpret the provisions of the Plan, (iii) supervise the administration of the Plan, (iv) make factual determinations relevant to Plan entitlements and (v) take all other actions in connection with administration of the Plan as it deems necessary or advisable, consistent with any delegation from the Board. Decisions of the Board and the Committee shall be final and binding upon all participants.

(b)                                 Without stockholder consent and without regard to whether any Participant rights may be considered to have been adversely affected, the Committee shall be entitled to change the timing of future Offering Periods, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond

8

with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Committee determines in its sole discretion advisable that are consistent with the Plan.

14.                                 Designation of Beneficiary. The Committee may establish rules pertaining to the designation by the Participant 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 an Offering Period.

15.                                 Transferability. During his or her lifetime, a Participant’s option to purchase Shares hereunder is exercisable only by him or her. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of an option or the receipt of 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 Section 14) 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 from the Plan in accordance with Section 10.

16.                                 Use of Funds. All Contributions 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 Contributions.

17.                                 Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be provided to Participants by the Company or the Designated Broker at least annually, which statements will set forth the amounts of Contributions, the per Share Purchase Price, the number of Shares purchased and the remaining cash balance, if any.

18.                                 Adjustments Upon Changes in Capitalization; Corporate Transactions.

(a)                                  Adjustment. Subject to any required action by the stockholders of the Company, in the event of any change in the Common Stock subject to the Plan or subject to or underlying any outstanding option, by reason of any stock dividend, stock split, reverse stock split, reorganization, recapitalization, merger, consolidation, spin-off, combination, exchange of Shares of Common Stock or other corporate exchange, or any distribution or dividend to stockholders of Common Stock (whether paid in cash or otherwise) or any transaction similar to the foregoing, the Board in its sole discretion and without liability to any person may make such substitution or adjustment, if any, as it deems to be equitable to (i) the number and kind of Shares or other securities that have been authorized for issuance under the Plan but have not yet been placed under option, including the number of Shares of Common Stock set forth in Section 12(a) above (collectively, the “Reserves”), (ii) the maximum number of Shares of Common Stock that may be purchased by a Participant and/or by all Participants in an Offering Period as set forth in Section 8, (iii) the number and kind of Shares or other securities covered by each option under the Plan that has not yet been exercised, (iv) the Purchase Price per Share of Common Stock covered by each option under the Plan that has not yet been exercised and (v) any other affected terms of the Plan or any outstanding option. 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

9

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 subject to an option.

(b)                                 Corporate Transactions.

(ii)                                  In the event of a Corporate Transaction, then in the sole discretion of the Board, (1) each option shall be assumed or an equivalent option shall be substituted by the successor corporation or parent or subsidiary of such successor entity, (2) a date established by the Board on or before the date of consummation of such Corporate Transaction shall be treated as a Purchase Date, and all outstanding options shall be exercised on such date, (3) all outstanding options shall terminate and all Contributions will be refunded to the Participants, or (4) all outstanding options shall continue unchanged.

19.                                 Amendment or Termination. The Board may, at any time and for any reason, terminate, suspend or amend the Plan; provided, however, that no such actions may adversely affect outstanding options except as provided in Section 18 and this Section 19. Notwithstanding the foregoing, the Board may terminate or suspend the Plan and/or an on-going Offering Period if the Board determines that such action is in the best interests of the Company and the stockholders. Upon a termination or suspension of the Plan, the Board may in its discretion (i) return without interest, the Contributions credited to Participants’ accounts to such Participants or (ii) set an earlier Purchase Date with respect to an Offering Period then in progress. The Company shall obtain stockholder approval of any amendments or terminations in such a manner and to such a degree as required by Applicable Law.

20.                                 Notices. All notices or other communications by an Employee 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.

21.                                 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 Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. In connection with the granting or exercise of an option, the Company may require a Participant to make such representations and warranties which, in the opinion of counsel for the Company, are required by Applicable Law.

22.                                 Term of Plan; Effective Date. This Plan shall be effective on the Effective Date, subject to approval of the stockholders of the Company within twelve (12) months before or after its date of adoption by the Board.

23.                                 Additional Restrictions of Rule 16b-3. The terms and conditions of options granted hereunder to, and the purchase of Shares by, persons subject to Section 16 of the Exchange Act shall comply with the applicable provisions of Rule 16b-3. This Plan shall be deemed to contain, and such options shall contain, and the Shares issued upon exercise thereof shall be subject to, such additional conditions and restrictions as may be required by Rule 16b-3 to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions.

24.                                 Rules for Foreign Jurisdictions. The Committee may adopt rules or procedures relating to the operation and administration of the Plan to accommodate the specific requirements of Applicable Laws. Without limiting the generality of the foregoing, the Committee is specifically authorized to adopt rules and procedures regarding handling of payroll deductions or other contributions by Participants, payment of interest, conversion of local currency, payroll tax, withholding procedures and handling of stock certificates which vary with local requirements; however, if such varying provisions are not in accordance with the provisions of Section 423(b) of the Code, including but not limited to the requirement of Section 423(b)(5) of the Code that all options granted under the Plan shall have the same rights and privileges unless otherwise provided under the Code and the regulations promulgated thereunder, then the individuals affected by such varying provisions shall be deemed to be participating under a sub-plan and not the Plan. The Committee may also adopt sub-plans applicable to particular Designated Subsidiaries or locations, which sub-plans may be designed to be outside the scope of Code section 423. The rules of such sub-plans may take precedence over other provisions of this Plan, with the exception of Section 12, but unless otherwise superseded by the terms of such sub-plan, the provisions of this Plan shall govern the operation of such sub-plan.

25.                                 No Enlargement of Rights.

2.                                       I elect to have Contributions in the amount of     % of my Compensation, as those terms are defined in the Plan, applied to this purchase. I understand that this amount must not be less than 1% and not more than 10% of my Compensation during the Offering Period. (Please note that no fractional percentages are permitted).

3.                                       I hereby authorize payroll deductions from each paycheck during each Offering Period at the rate stated in Item 2 of this Subscription Agreement. I understand that all payroll deductions made by me shall be credited to my account under the Plan and that I may not make any additional payments into such account. I understand that all Contributions made by me shall be accumulated for the purchase of Shares of Common Stock at the applicable Purchase Price determined in accordance with the Plan. I further understand that, except as otherwise set forth in the Plan, Shares will be purchased for me automatically on the Purchase Date of each Offering Period unless my employment is terminated prior to the Purchase Date or I otherwise withdraw from the Plan by giving written notice to the Company for such purpose.

4.                                       I understand that I may discontinue at any time prior to the Purchase Date my participation in the Plan as provided in Section 10 of the Plan. I also understand that I can decrease the rate of my Contributions on one occasion only during any Offering Period by completing and filing a new Subscription Agreement with such decrease taking effect as of the beginning of the payroll period following the date of filing of the new Subscription Agreement, if filed at least five (5) business days prior to the beginning of such payroll period. Further, I may change the rate of deductions for future Offering Periods by filing a new Subscription Agreement, and any such change will be effective as of the beginning of the next Offering Period.

8.                                       I understand that if I dispose of any Shares received by me pursuant to the Plan within 2 years after the Offering Date (the first day of the Offering Period during which I purchased such Shares) or within 1 year after the Purchase Date, I will be treated for US federal income tax purposes as having received ordinary compensation income at the time of such disposition in an amount equal to the excess of the fair market value of the Shares on the Purchase Date over the price that I paid for the Shares, regardless of whether I disposed of the Shares at a price less than their fair market value at the Purchase Date. The remainder of the gain or loss, if any, recognized on such disposition will be treated as capital gain or loss.

I hereby agree to notify the Company in writing within 30 days after the date of any such disposition, and I will make adequate provision for federal, state or other tax withholding obligations, if any, that arise upon the disposition of the Common Stock. The Company may, but will not be obligated to, withhold from my compensation the amount necessary to meet any applicable withholding obligation including with respect to taxes attributable to the sale or early disposition of Common Stock by me.

I understand that this tax summary is only a summary and is subject to change. I acknowledge that I have received a copy of the Plan prospectus, and that additional information regarding the tax consequences of my participation in the Plan can be found in the prospectus.
