6. Plan Contributions.

(a) Contribution by Payroll Deduction. Except with respect to the first Offering Period, and except as otherwise authorized by the Committee, all contributions to the Plan shall be made only by payroll deductions. The Committee may, but need not, permit Participants on a uniform and non-discriminatory basis to make after-tax contributions to the Plan at such times and subject to such terms and conditions as the Committee may in its discretion determine. All such additional contributions shall be made in a manner consistent with the provisions of Section 423 of the Code or any successor thereto, and shall be treated in the same manner as payroll deductions contributed to the Plan as provided herein.

(b) Payroll Deduction Election on Enrollment Agreement. At the time a Participant files the enrollment agreement with respect to an Offering Period, the Participant may authorize payroll deductions to be made on each payroll date during the portion of the Offering Period that he or she is a Participant in an amount not less than 1% and not more than fifteen percent (15%) (or such other percentage as determined by the Committee and announced at least five (5) days prior to the first day of the Offering Period in which such change is to be made effective) of the Participant’s

4

Compensation on each payroll date during the portion of the Offering Period that he or she is a Participant. The amount of payroll deductions must be a whole percentage (e.g., 1%, 2%, 3%, etc.) of the Participant’s Compensation.

(c) Commencement of Payroll Deductions. Except as otherwise determined by the Committee under rules applicable to all Participants, payroll deductions for Participants enrolling in the Plan after the First Offering Date under Section 5(b) shall commence with the earliest administratively practicable payroll period that begins on or after the Entry Date with respect to which the Participant files an enrollment agreement in accordance with Section 5(b).

(d) Automatic Continuation of Payroll Deductions. Unless a Participant elects otherwise prior to the last day of an Offering Period, such Participant shall be deemed (i) to have elected to participate in the immediately succeeding Offering Period (and, for purposes of such Offering Period the Participant’s “Entry Date” shall be deemed to be the first day of such Offering Period) and (ii) to have authorized the same payroll deduction for the immediately succeeding Offering Period as was in effect for the Participant immediately prior to the commencement of the succeeding Offering Period.

(e) Change of Payroll Deduction Election. A Participant may decrease or increase the rate or amount of his or her payroll deductions during an Offering Period (within the limitations of Section 6(b) above) by completing and filing with the Company a new enrollment agreement authorizing a change in the rate or amount of payroll deductions; provided, that a Participant may not change the rate or amount of his or her payroll deductions more than two times in any Offering Period. Except as otherwise determined by the Committee under rules applicable to all Participants, the change in rate or amount shall be effective as of the earliest administratively practicable payroll period that begins on or after the date the Committee receives the new enrollment agreement. Additionally, a Participant may discontinue his or her participation in the Plan as provided in Section 13(a).

(f) Automatic Changes in Payroll Deduction. Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code, Section 7(d) hereof, or any other applicable law, a Participant’s payroll deductions may be decreased, including 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 are equal to the product of $25,000 multiplied by the Applicable Percentage for the calendar year. Payroll deductions shall recommence at the rate provided in the Participant’s enrollment agreement at the beginning of the following Offering Period which is scheduled to end in the following calendar year, unless the Participant terminates participation as provided in Section 13(a).

(g) Special Rule for the Initial Offering Period.

i. Prior to Effectiveness of Form S-8. No payroll deductions shall be made (and no payroll deduction elections shall be accepted) by the Company for Participants during the initial Offering Period prior to the time that a registration statement with respect to the shares of Common Stock being offered under the Plan has been filed with the Securities and Exchange Commission on Form S-8, and is effective. Each Participant shall be eligible to purchase shares of Common Stock on the Exercise Date of the initial Offering Period in an amount equal to the lesser of (A) the aggregate purchase price for Two Thousand (2,000) shares of Common Stock or (B) fifteen percent (15%) of the Compensation that the Participant receives during the initial Offering Period.

ii. After Effectiveness of Form S-8. Once the registration statement with respect to the shares of Common Stock being offered under the Plan has been filed with the Securities and

5

Exchange Commission on Form S-8, and is effective, a Participant may, but need not, make a payroll deduction election with respect to the initial Offering Period by filing an enrollment agreement containing the payroll deduction election with the Company, as provided in Section 6(b) above. A Participant may elect a lower level of participation than that provided in Section 6(g)(i) above with respect to the initial Offering Period at that time, or may withdraw from the Plan. If a Participant does not file an enrollment agreement within sixty (60) days of the effective date of the registration statement with respect to the shares of Common Stock being offered under the Plan that was filed with the Securities and Exchange Commission on Form S-8, the Participant is deemed to have withdrawn from the Plan pursuant to Section 13(a) hereof. If a payroll deduction is elected under this Section 6(g)(ii), payroll deductions may commence as early as with the first pay period beginning after the First Offering Date. Subject to the overall participation level specified in Section 6(g)(i), the rate of payroll deduction during the initial Offering Period may exceed the maximum permitted rate under Section 6(b) hereof to make up for the payroll deductions, if any, which would otherwise have been made prior to the effectiveness of the Form S-8 with respect to the Plan. If a payroll deduction election is made under this Section 6(g)(ii), payroll deductions shall continue at the rate elected by the Participant for subsequent Offering Periods (or at lesser amounts as shall be required to comply with the limits under Section 6(b) hereof), unless the Participant makes a change permitted under Section 6(e), or withdraws from the Plan under Section 13(a). Alternatively, the Committee may permit purchases on the first Exercise Date of the initial Offering Period to be made by direct lump sum cash transfer by the Participant.

iii. Subsequent Offering Periods. For all Offering Periods subsequent to the initial Offering Period, purchases generally must be made via payroll deduction. Participants in the initial Offering Period who do not make a payroll deduction election pursuant to Section 6(g)(ii) must file an enrollment agreement containing a payroll deduction election with respect to subsequent Offering Periods with the Company prior to the commencement of a subsequent Offering Period (unless a later time for filing is set by the Committee for all Participants) in order to make further purchases under the Plan. Payroll deductions for Participants required to file a payroll deduction election under this Section 6(g)(iii) shall commence, except as otherwise determined by the Committee under rules applicable to all Participants, effective as of the earliest administratively practicable payroll period that begins on or after the first day of the subsequent Offering Period. A Participant who does not timely file an enrollment agreement shall be treated as having withdrawn under Section 13(a) hereof.

7. Grant of Option.

(a) Shares of Common Stock Subject to Option. On a Participant’s Entry Date, subject to the limitations set forth in Section 7(d) and this Section 7(a), the Participant shall be granted an option to purchase on the Exercise Date during the Offering Period in which such Entry Date occurs (at the Exercise Price determined as provided in Section 7(b) below) up to a number of shares of Common Stock determined by dividing such Participant’s Plan Contributions accumulated prior to such Exercise Date and retained in the Participant’s account as of such Exercise Date by the Exercise Price; provided, that the maximum number of shares a Participant may purchase during any Offering Period shall be Two Thousand (2,000) shares, or such other amount as determined by the Committee and announced at least five (5) days prior to the first day of the Offering Period in which such change is to be made effective.

(b) Exercise Price. The Exercise Price per share of Common Stock offered to each Participant in a given Offering Period shall be the lower of: (i) the Applicable Percentage of the Fair Market Value of a share of Common Stock on the Offering Date, or (ii) the Applicable Percentage of the Fair Market Value of a share of Common Stock on the Exercise Date.

(c) Fair Market Value. The Fair Market Value of a share of Common Stock on a given date shall be determined by the Committee or under procedures established by the Committee.

6

Unless otherwise determined by the Committee, the Fair Market Value of a share of Common Stock as of any given date shall be the closing sale price per share reported on a consolidated basis for stock listed on the principal stock exchange or market on which shares are traded on the date as of which such value is being determined, or, if there is no sale on that date, then on the last previous day on which a sale was reported. For purposes of the First Offering Date, the Fair Market Value of a share of Common Stock shall be the Price to Public as set forth in the final prospectus filed by the Company with the Securities and Exchange Commission pursuant to Rule 424 under the Securities Act of 1933, as amended.

(d) Limitation on Options that may be Granted. Notwithstanding any provision of the Plan to the contrary, no Participant shall be granted an option under the Plan (i) to the extent that if, immediately after the grant, such Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 424(d) of the Code) would own stock and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the total combined voting power or value of all classes of stock of the Company or of any Subsidiary of the Company, or (ii) to the extent that his or her rights to purchase stock under all employee stock purchase plans of the Company and its Subsidiaries intended to qualify under Section 423 of the Code accrue at a rate which exceeds $25,000 of Fair Market Value of Common Stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time.

(e) No Rights as Stockholder. A Participant will have no interest or voting right in shares covered by his or her option until such option has been exercised.

8. Exercise of Options.

(a) Automatic Exercise. A Participant’s option for the purchase of shares shall be exercised automatically on each Exercise Date, and the maximum number of full shares subject to the option shall be purchased for the Participant at the applicable Exercise Price with the accumulated Plan Contributions then credited to the Participant’s account under the Plan. During a Participant’s lifetime, a Participant’s option to purchase shares hereunder is exercisable only by the Participant.

(b) Carryover of Excess Contributions. Any amount remaining to the credit of a Participant’s account after the purchase of shares by the Participant on an Exercise Date, or which is insufficient to purchase a full share of Common Stock, shall remain in the Participant’s account, and be carried over to the next Offering Period, unless the Participant withdraws from participation in the Plan or elects to withdraw his or her account balance in accordance with Section 10(c).

9. Issuance of Shares.

(a) Delivery of Shares. As promptly as practicable after each Exercise Date, the Company shall arrange for the delivery to each Participant (or the Participant’s beneficiary), as appropriate, or to a custodial account held by a custodian appointed by the Company for the benefit of each Participant (or the Participant’s beneficiary), as appropriate, of a certificate representing the shares purchased upon exercise of the Participant’s option or, at the Company’s option, through appropriate book entry procedures. The Company may require that shares be retained with such custodian for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such shares.

(b) Registration of Shares. 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, as requested by the Participant.

7

(c) Compliance with Applicable Laws. The Plan, the grant and exercise of options to purchase shares under the Plan, and the Company’s obligation to sell and deliver shares upon the exercise of options to purchase shares shall be subject to compliance with all applicable federal, state, and foreign laws, rules, and regulations and the requirements of any stock exchange on which the shares may then be listed.

(d) Withholding. The Company may make such provisions as it deems appropriate for withholding by the Company pursuant to federal or state tax laws of such amounts as the Company determines it is required to withhold in connection with the purchase or sale by a Participant of any Common Stock acquired pursuant to the Plan. The Company may require a Participant to satisfy any relevant tax requirements before authorizing any issuance of Common Stock to such Participant.

10. Participant Accounts.

(a) Bookkeeping Accounts Maintained. Individual bookkeeping accounts will be maintained for each Participant in the Plan to account for the balance of his Plan Contributions, options issued, and shares purchased under the Plan. However, all Plan Contributions made for a Participant shall be deposited in the Company’s general corporate accounts, and no interest shall accrue or be credited with respect to a Participant’s Plan Contributions. All Plan Contributions received or held by the Company may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate or otherwise set apart such Plan Contributions from any other corporate funds.

(b) Participant Account Statements. Statements of account will be given to Participants semi-annually in due course following each 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.

(c) Withdrawal of Account Balance Following Exercise Date. A Participant may elect at any time within the first thirty (30) days following any Offering Period, or at such other time as the Committee may from time to time prescribe, to receive in cash any amounts carried-over in accordance with Section 8(b). An election under this Section 10(c) shall not be treated as a withdrawal from participation in the Plan under Section 13(a).

11. Designation of Beneficiary.

(a) Designation. 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 the Participant’s death subsequent to an Exercise Date on which the Participant’s option hereunder is exercised but prior to delivery to the Participant 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 the Participant’s death prior to the exercise of the option.

(b) Change of Designation. A Participant’s beneficiary designation 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.

8

12. Transferability. Neither Plan Contributions credited to a Participant’s account nor any rights to exercise any option or receive shares of Common Stock under the Plan may be assigned, transferred, pledged, or otherwise disposed of in any way (other than by will or the laws of descent and distribution, or as provided in Section 11). Any attempted assignment, transfer, pledge, or other distribution shall be without effect, except that the Company may treat such act as an election to withdraw in accordance with Section 13(a).

13. Withdrawal; Termination of Employment.

(a) Withdrawal. A Participant may withdraw from the Plan at any time after the Company’s registration statement on Form S-8 with respect to the Plan is effective by giving written notice to the Company. Payroll deductions, if any have been authorized, shall cease as soon as administratively practicable after receipt of the Participant’s notice of withdrawal, and, subject to administrative practicability, no further purchases shall be made for the Participant’s account. All Plan Contributions credited to the Participant’s account, if any, and not yet invested in Common Stock, will be paid to the Participant as soon as administratively practicable after receipt of the Participant’s notice of withdrawal. The Participant’s unexercised options to purchase shares pursuant to the Plan automatically will be terminated. Payroll deductions will not resume on behalf of a Participant who has withdrawn from the Plan (a “Former Participant”) unless the Former Participant enrolls in a subsequent Offering Period in accordance with Section 5(b).

(b) Effect of Withdrawal on Subsequent Participation. A Participant’s withdrawal from an Offering Period will not have any effect upon the Participant’s eligibility to participate in succeeding Offering Periods or in any similar plan which may hereafter be adopted by the Company.

(c) Termination of Employment. Upon termination of a Participant’s Continuous Status as an Employee prior to any Exercise Date for any reason, including retirement or death, the Plan Contributions credited to the Participant’s account and not yet invested in Common Stock will be returned to the Participant or, in the case of death, to the Participant’s beneficiary as determined pursuant to Section 11, and the Participant’s option to purchase shares under the Plan will automatically terminate.

14. Common Stock Available under the Plan.

(a) Number of Shares. Subject to adjustment as provided in Section 14(b) below, the maximum number of shares of the Company’s Common Stock that shall be made available for sale under the Plan shall be 2,000,000 shares, plus an automatic annual increase on the first day of each of the Company’s fiscal years beginning in 2013 and ending in 2022 equal to the lesser of (i) 1,500,000 shares, (ii) one percent (1%) of all shares of Common Stock outstanding on the last day of the immediately preceding fiscal year, or (iii) a lesser amount determined by the Board. Shares of Common Stock subject to the Plan may be newly issued shares or shares reacquired in private transactions or open market purchases. If and to the extent that any right to purchase reserved shares shall not be exercised by any Participant for any reason or if such right to purchase shall terminate as provided herein, shares that have not been so purchased hereunder shall again become available for the purpose of the Plan unless the Plan shall have been terminated, but all shares sold under the Plan, regardless of source, shall be counted against the limitation set forth above.

(b) Adjustments Upon Changes in Capitalization; Corporate Transactions.

i. If the outstanding shares of Common Stock are increased or decreased, or are changed into or are exchanged for a different number or kind of shares, as a result of one or more

9

reorganizations, restructurings, recapitalizations, reclassifications, stock splits, reverse stock splits, stock dividends, or the like, then the Committee shall, in such manner as it may deem equitable, substitute, exchange, or adjust any or all of the number and/or kind of shares, and the per-share option price thereof, which may be issued in the aggregate and to any Participant upon exercise of options granted under the Plan, including, without limitation, the maximum number of shares a Participant may purchase during any Offering Period under Section 7(a) hereof.

ii. 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 Committee.

iii. In the event of a proposed sale of all or substantially all of the Company’s assets, or the merger of the Company with or into another corporation (each, a “Sale Transaction”), 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 Committee determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, to shorten the Offering Period then in progress by setting a new Exercise Date (the “New Exercise Date”). If the Committee shortens the Offering Period then in progress in lieu of assumption or substitution in the event of a Sale Transaction, the Committee shall notify each Participant in writing, at least ten (10) days prior to the New Exercise Date, that the exercise date for such Participant’s option has been changed to the New Exercise Date and that such Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Plan as provided in Section 13(a). For purposes of this Section 14(b), an option granted under the Plan shall be deemed to have been assumed if, following the Sale Transaction, the option confers the right to purchase, for each share of option stock subject to the option immediately prior to the Sale Transaction, the consideration (whether stock, cash, or other securities or property) received in the Sale Transaction by holders of Common Stock for each share of Common Stock held on the effective date of the Sale Transaction (and if such holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding shares of Common Stock); provided, that if the consideration received in the Sale Transaction was not solely common stock of the successor corporation or its parent (as defined in Section 424(e) of the Code), the Committee may, with the consent of the successor corporation and the Participant, provide for the consideration to be received upon exercise of the option to be solely common stock of the successor corporation or its parent equal in fair market value to the per share consideration received by the holders of Common Stock in the Sale Transaction.

iv. In all cases, the Committee shall have sole discretion to exercise any of the powers and authority provided under this Section 14, and the Committee’s actions hereunder shall be final and binding on all Participants. No fractional shares of Common Stock shall be issued under the Plan pursuant to any adjustment authorized under the provisions of this Section 14.

15. Administration.

(a) Committee. The Plan shall be administered by the Committee. The Committee shall have the authority to interpret the Plan, to prescribe, amend, and rescind rules and regulations relating to the Plan, and to make all other determinations necessary or advisable for the administration of the Plan. The administration, interpretation, or application of the Plan by the Committee shall be final, conclusive, and binding upon all persons.

(b) Requirements of Exchange Act. Notwithstanding the provisions of Section 15(a) above, in the event that Rule 16b-3 promulgated under the Exchange Act or any successor provision thereto (“Rule 16b-3”) provides specific requirements for the administrators of plans of this

10

type, the Plan shall only be administered by such body and in such a manner as shall comply with the applicable requirements of Rule 16b-3. Unless permitted by Rule 16b-3, no discretion concerning decisions regarding the Plan shall be afforded to any person that is not “disinterested” as that term is used in Rule 16b-3.

16. Amendment, Suspension, and Termination of the Plan.

(a) Amendment of the Plan. The Board or the Committee may at any time, or from time to time, amend the Plan in any respect; provided, that (i) no such amendment may make any change in any option theretofore granted which adversely affects the rights of any Participant and (ii) the Plan may not be amended in any way that will cause rights issued under the Plan to fail to meet the requirements for employee stock purchase plans as defined in Section 423 of the Code or any successor thereto. To the extent necessary to comply with Rule 16b-3 under the Exchange Act, Section 423 of the Code, or any other applicable law or regulation, the Company shall obtain stockholder approval of any such amendment.

(b) Suspension of the Plan.
