5.    Participation. An Eligible Employee may become a participant in the Plan by enrolling via E*Trade or completing a subscription agreement authorizing payroll deductions in the form of Exhibit A to this Plan and filing it with the Company's stock plan administrator, on a date determined by such administrator, which shall be no later than five (5) Trading Days prior to the applicable Entry Date.

(a)    At the time a participant enrolls via E*Trade or files his or her subscription agreement, he or she shall elect to have payroll deductions made on each pay day during the Offering Period in any multiple of one-percent (1%), but not exceeding ten-percent (10%) of the Compensation which he or she receives during each Purchase Period; provided, however, that should a payday occur on an Exercise Date, a participant shall have the payroll deductions made on such day applied to his or her account under the new Offering Period or Purchase Period, as the case may be. A participant's elections via E*Trade enrollment or a subscription agreement shall remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof.

(b)    Payroll deductions for a participant shall commence on the first payday following the Entry Date and shall end on the last payday in the Offering Period to which such authorization is applicable, unless sooner terminated by the participant as provided in Section 10 hereof. All payroll deductions made for a participant shall be credited to his or her account under the Plan and shall be withheld in whole percentages only. 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 Section 10 hereof, or may decrease (but not increase) the rate of his or her payroll deductions during the Offering Period by changing deductions via E*Trade or completing or filing with the Company a new subscription agreement authorizing a change in payroll deduction rate. No more than one (1) such reduction shall be allowed in any Purchase Period. A participant may only increase the rate of his or her payroll deductions beginning with the next Offering Period which lasts 24 months. The change in rate shall be effective as soon as administratively practicable.

(d)    Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's payroll deductions may be decreased to zero percent (0%) at any time during a Purchase Period. Payroll deductions shall recommence at the rate provided in such participant's E*Trade elections or subscription agreement at the beginning of the first Purchase Period which is scheduled to end in the following calendar year, unless terminated by the participant as provided in Section 10 hereof.

(e)    At the time the option is exercised, in whole or in part, or at the time some or all of the Company's Common Stock issued under the Plan is disposed of, the participant must make adequate provision for the Company's federal, state, or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock. At any time, the Company may, but shall not be obligated to, withhold from the participant's compensation the amount necessary for the Company to meet applicable withholding obligations, including any withholding required to make available to the Company any tax deductions or benefits attributable to sale or early disposition of Common Stock by the Eligible Employee.

7.    Grant of Option. On the Entry 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 (at the applicable Purchase Price) up to a number of shares of the Company's Common Stock determined by dividing such Eligible Employee's payroll deductions accumulated prior to such Exercise Date and retained in the Participant's account as of the Exercise Date by the applicable Purchase Price; provided that in no event shall an Eligible Employee be permitted to purchase during each Purchase Period more than 7,500¹ shares of the Company's Common Stock (subject to any adjustment pursuant to Section 19), and provided further that such purchase shall be subject to the limitations set forth in Sections 3(b) and 6 hereof. The Eligible Employee may accept the grant of such option by enrolling via E*Trade or turning in a completed Subscription Agreement (attached hereto as Exhibit A) to the stock plan administrator, on a date determined by such administrator, which shall be no later than five (5) Trading Days prior to an applicable Entry Date. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of the Company's Common Stock an Eligible Employee may purchase during each Purchase Period of such Offering Period. Exercise of the option shall occur as provided in Section 8 hereof, unless the participant has withdrawn pursuant to Section 10 hereof. The option shall expire on the last day of the Offering Period.

8.    Exercise of Option.

(a)    Unless a participant withdraws from the Plan as provided in Section 10 hereof, his or her option for the purchase of shares shall be exercised automatically on the Exercise Date, and the maximum number of full shares subject to option shall be purchased for such participant at the applicable Purchase Price with the accumulated payroll deductions in his or her account. No fractional shares shall be purchased; any payroll deductions accumulated in a participant's account which are not sufficient to purchase a full share shall be retained in the participant's account for the subsequent Purchase Period or Offering Period, subject to earlier withdrawal by the participant as provided in Section 10 hereof. Any other funds left over in a participant's account after the Exercise Date shall be returned to the participant. During a participant's lifetime, a participant's option to purchase shares hereunder is exercisable only by him or her.

(b)    If the Administrator determines that, on a given Exercise Date, the number of shares with respect to which options are to be exercised may exceed (i) the number of shares of Common Stock that were available for sale under the Plan on the Entry Date of the applicable Offering Period, or (ii) the number of shares available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company shall make a pro rata allocation of the shares of Common Stock available for purchase on such Entry Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect, or (y) provide that the Company shall make a pro rata allocation of the shares available for purchase on such Entry Date or Exercise Date, as applicable, in as uniform a manner as shall be practicable and as it shall determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 20 hereof. The Company may make pro rata allocation of the shares available on the Entry Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional shares for issuance under the Plan by the Company's shareholders subsequent to such Entry Date.

9.    Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of shares occurs, the Company shall arrange the delivery to each participant the shares purchased upon exercise of his or her option in a form determined by the Administrator.

10.    Withdrawal.

(a)    At any time prior to the last five (5) Trading Days of a Purchase Period, a participant may withdraw from the Plan by giving written notice to the Company in the form of Exhibit A to this Plan. The participant shall elect to either have (i) all of the participant's payroll deductions credited to his or her account used to purchase shares at the next Exercise Date or (ii) all payroll deductions credited to his or her account refunded. In neither event will any further payroll deductions for the purchase of shares be made for such Offering Period. If a participant withdraws from an Offering Period, the participant may not re-enroll in the Plan until the next Offering Period which lasts 24 months, and payroll deductions shall not resume at the beginning of such Offering Period unless the participant re-enrolls in the Plan via E*Trade or delivers to the Company a new subscription agreement in a manner provided for in Section 5.

(b)    A participant's withdrawal from an Offering Period shall not have any effect upon his or her eligibility to participate in any similar plan which may hereafter be adopted by the Company.

11.    Termination of Employment. In the event a participant ceases to be an Eligible Employee of the Company or any Participating Company (other than as a result of death or Permanent Disability), any payroll deductions credited to such participant's account during the Offering Period but not yet used to purchase shares under the Plan shall be returned to such participant and such participant's option shall be automatically terminated. In the event a participant ceases to be an Employee of the Company or any Participating Company as a result of death or Permanent Disability, then such participant (or personal representative of the estate of the deceased participant) may elect at any time prior to the last five (5) Trading Days of a Purchase Period in which such termination occurs, to (i) have all of such

participant’s payroll deductions for such Purchase Period refunded to the Participant or (ii) have all such payroll deductions used to purchase the Company’s common stock on the Exercise Date following such termination.

12.    Interest. No interest shall accrue on the payroll deductions of a participant in the Plan.

13.    Stock.

(a)    Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the number of shares of the Company's Common Stock which shall be made available for sale under the Plan shall be 3,275,000 shares, plus up to 150,000 remaining unissued shares available as of the Effective Date under the Company’s previous ESPP, and plus beginning January 1, 2005, and each January 1 thereafter during the term of the Plan, an automatic annual increase in shares reserved of the lesser of (i) 1,500,000 shares, (ii) one half of one percent (0.5%) of the then outstanding shares of our common stock, or (iii) such lesser amount as is approved by our Board of Directors²; provided, however, that the shares under the Company’s previous ESPP shall not be available for issuance under the Plan to the extent that such reservation would, in the opinion of the Company’s independent auditors, result in a compensation expense to the Company under either EITF 97-12 or ASC 718³.

(b)    Until the shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a participant shall only have the rights of an unsecured creditor with respect to such shares, and no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to such shares.

(c)    Shares to be delivered to a participant under the Plan shall be held in a brokerage account in street name.

14.    Administration. The Administrator shall administer the Plan and shall have full and exclusive discretionary authority to construe, interpret and apply the terms of the Plan, to determine eligibility and to adjudicate all disputed claims filed under the Plan. Every finding, decision and determination made by the Administrator shall, to the full extent permitted by law, be final and binding upon all parties.

15.    Designation of Beneficiary.

(a)    A participant may file a written designation of a beneficiary who is to receive any payroll deductions, if any, from the participant's account under the Plan in the event of such participant's death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such participant of such payroll deductions.

In addition, a participant may file a written designation of a beneficiary who is to receive any payroll deductions from the participant's account under the Plan in the event of such participant's death prior to exercise of the option. If a participant is married and the designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective.

(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 payroll deductions 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 payroll deductions 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.

(c)    All beneficiary designations shall be in such form and manner as the Administrator may designate from time to time.

16.    Transferability. 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 Section 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 from an Offering Period in accordance with Section 10 hereof.

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. Until shares are issued, participants shall only have the rights of an unsecured creditor.

18.    Reports. Individual accounts shall be maintained for each participant in the Plan. Statements of account shall be given to participating Eligible Employees at least annually, which statements shall set forth the amounts of payroll deductions, the Purchase Price, the number of shares purchased and the remaining cash balance, if any.

19.    Adjustments Upon Changes in Capitalization, Dissolution, Liquidation, Merger or Change of Control.

(a)    Changes in Capitalization. Subject to any required action by the shareholders of the Company, the maximum number of shares of the Company’s Common Stock which shall be made available for sale under the Plan, the maximum number of shares each participant may purchase each Purchase Period (pursuant to Section 7), as well as the price per share and the number of shares 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 change 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 Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance 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.

(b)    Change in Control. In the event of a Change of Control, each outstanding option shall be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the option, any Purchase Periods then in progress shall be shortened by setting a New Exercise Date and any Offering Periods then in progress shall end on the New Exercise Date. The New Exercise Date shall be before the date of the Company's proposed Change of Control. The Administrator shall notify each participant in writing, at least 10 business days prior to the New Exercise Date, that the Exercise Date for the participant's option has been changed to the New Exercise Date and that the participant's option shall be exercised automatically on the New Exercise Date, unless prior to such date the participant has withdrawn from the Offering Period as provided in Section 10 hereof.

(a)    The Administrator may at any time and for any reason terminate or amend the Plan. Except as otherwise provided in the Plan, no such termination can affect options previously granted, provided that an Offering Period may be terminated by the Administrator on any Exercise Date if the Administrator determines that the termination of the Offering Period or the Plan is in the best interests of the Company and its shareholders. Except as provided in Section 19 and this Section 20 hereof, no amendment may make any change in any option theretofore granted which adversely affects the rights of any participant. To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other applicable law, regulation or stock exchange rule), the Company shall obtain shareholder approval in such a manner and to such a degree as required.

(b)    Without shareholder consent and without regard to whether any participant rights may be considered to have been "adversely affected," the Administrator shall be entitled to change the 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 with amounts withheld from the participant's Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable which are consistent with the Plan.

(c)    In the event the Administrator 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 to reduce or eliminate such accounting consequence including, but not limited to:

(i)    increasing the Purchase Price for any Offering Period including an Offering Period underway at the time of the change in Purchase Price;

(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; and

(iii)    allocating shares.

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 and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

22.    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 Securities Exchange Act of 1934, as amended, 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.

23.    Term of Plan. The Plan, as amended through May 19, 2014, shall continue in effect until August 31, 2024, unless sooner terminated under Section 20 hereof.

24.    Automatic Transfer to Low Price Offering Period. To the extent permitted by any applicable laws, regulations, or stock exchange rules if the Fair Market Value of the Common Stock on any Exercise Date in an Offering Period is lower than the Fair Market Value of the Common Stock on the Entry Date of such Offering Period, then all participants in such Offering Period shall be automatically withdrawn from such Offering Period immediately after the exercise of their option on such Exercise Date and automatically re-enrolled in the immediately following Offering Period.
