Any interpretation, finding, determination, decision or other action made or taken by the Administrator shall be final, binding, and conclusive on all interested parties. The Administrator’s discretion set forth herein shall not be limited by any provision of the Plan, including any provision which by its terms is applicable notwithstanding any other provision of the Plan to the contrary. The Administrator may delegate to officers of the Company, pursuant to a written delegation, the authority to perform specified functions under the Plan. Any actions taken by any officers of the Company pursuant to such written delegation of authority shall be deemed to have been taken by the Committee.

4. Eligibility. Subject to the requirements of Section 6, any Eligible Employee on a given Offering Date shall be eligible to participate in the Plan for such Offering Period. Notwithstanding any provisions of the Plan to the contrary, no Eligible Employee shall be granted an Option under the Plan (i) to the extent that, immediately after the grant, such Eligible Employee (or any other person whose stock would be attributed to such Eligible Employee pursuant to Section 424(d) of the Code) would own capital stock of the Company and/or hold outstanding options under this Plan or any other plan or agreement with the Company to purchase such stock possessing five percent (5%) or more of the total combined voting power or value of all classes of the capital stock of the Company or of any Subsidiary, or (ii) to the extent that his or her rights to purchase stock under all “employee stock purchase plans” (within the meaning of Section 423(b) of the Code) of the Company and its Subsidiaries accrues at a rate which exceeds Twenty-Five Thousand Dollars ($25,000) (or such other maximum as may be prescribed from time to time by the Code) worth of stock (determined at the Fair Market Value of the shares of Common Stock at the time such Option is granted) for each calendar year in which such Option is outstanding at any time, in accordance with the provisions of Section 423(b)(8) of the Code.

5. Offering Periods. The Plan shall be implemented through consecutive, overlapping Offering Periods with a new Offering Period commencing on the fourth Trading Day on or after May 15 and November 15 of each year, or on such other date as the Board shall determine, and continuing thereafter until terminated in accordance with Section 18 hereof; provided, however, the first Offering Period under the Plan shall be the Offering Period that commenced on May 18, 2015. The Board shall have the power to change the duration and/or frequency of Offering Periods (including the commencement dates thereof) with respect to future offerings without stockholder approval if such change is announced prior to the scheduled beginning of the first Offering Period to be affected thereafter.

6. Participation. An Eligible Employee may become a Participant in the Plan by completing a Subscription Agreement, in the form attached hereto as Exhibit A, and filing it with the Company’s payroll office or the transfer agent, stock brokerage or other financial services firm designated or approved by the Administrator from time to time (the “Designated Agent”) at least fourteen (14) days prior to the applicable Offering Date. Subscription Agreements shall contain the Eligible Employee’s authorization and consent to the Company’s withholdings from his or her Compensation the amount of his or her contributions as set forth in Section 7 below. A Subscription Agreement shall automatically remain valid for successive Offering Periods until revoked or otherwise terminated pursuant to a Notice of Withdrawal filed in accordance with Section 10 hereof.

7. Participant Accounts; Payroll Deductions.

(a) The Company shall maintain on its books, or cause to be maintained by a record keeper, an Account in the name of each Participant. At the time an Eligible Employee files his or her Subscription Agreement, he or she shall make an election for a whole percentage of his or her Compensation, not exceeding ten percent (10%) of the Compensation that he or she receives on each pay day during the Offering Period, to be deducted each payday during the Offering Period and credited to his or her Account; 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 following Offering Period or Purchase Period, as the case may be. Such payroll deductions shall be credited to that Participant’s Account as soon as administratively practicable after the payday the payroll deduction is taken.

(b) Payroll deductions for a Participant shall commence on the first payday following the Offering 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.

(c) A Participant may not make any payments to his or her Account other than the payroll deductions he or she elects under his or her Subscription Agreement. A Participant’s Account shall be reduced by any amounts used to pay the Purchase Price of shares of Common Stock acquired, or by any other amounts distributed pursuant to the terms hereof.

(d) A Participant may discontinue his or her participation in the Plan as provided in Section 10 hereof, or may increase or decrease the rate of his or her payroll

6

deductions during the Offering Period by completing or filing with the Company a new Subscription Agreement authorizing a change in payroll deduction rate. The Administrator may, in its discretion, limit the nature and/or number of participation rate changes during any Offering Period. The change in rate shall be effective with the first full payroll period following ten (10) business days after the Company’s receipt of the new Subscription Agreement, unless the Company elects, in its discretion, to process a given change in participation more quickly.

(e) Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 4 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 Subscription Agreement at the beginning of the first Purchase Period which is scheduled to end in the following calendar year, unless sooner terminated by the Participant as provided in Section 10 hereof.

(f) No interest shall accrue on the payroll deductions held in a Participant’s Account.

8. Grant of Option. On the Offering Date of each Offering Period, each Participant in such Offering Period shall be granted an Option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) the number of whole shares of 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; and provided that such purchase shall be subject to the limitations set forth in Sections 4 and 12 hereof. The Eligible Employee may accept the grant of such Option by turning in a completed Subscription Agreement to the Company on or prior to an Offering Date. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of shares of the 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 9 hereof, unless the Participant has filed a Notice of Withdrawal in accordance with Section 10 hereof. Each Option shall expire on the last day of its Offering Period.

9. Exercise of Option.

(a) Unless a Participant files a Notice of Withdrawal as provided in Section 10 hereof, his or her Option for the purchase of shares shall be exercised automatically on the Exercise Date(s) of an Offering Period, and the maximum number of whole shares of Common Stock subject to the 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 of Common Stock shall be sold or issued pursuant to the Plan; any payroll deductions accumulated in a Participant’s Account which are not sufficient to purchase a whole share shall be retained in the Account for the subsequent Purchase Period or Offering Period, as applicable, subject to earlier withdrawal by the Participant as provided in Section 10 hereof. During a Participant’s lifetime, a Participant’s Option to purchase shares of Common Stock hereunder is exercisable only by him or her.

7

(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 Offering 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 Offering 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 Offering 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 19 hereof. The Company may make pro-rata allocation of the shares available on the Offering 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 stockholders subsequent to such Offering Date.

(c) As soon as reasonably practicable after each Exercise Date on which a purchase of Common Stock occurs, the Company shall electronically register the shares of Common Stock purchased upon exercise of his or her Option in the name of such Participant. No stock certificate or certificates shall be issued with respect to shares of Common Stock purchased upon exercise of an Option unless (i) the Participant requests delivery of the certificate or certificates by submitting a written request to the Administrator requesting delivery of the certificates, or (ii) the Administrator elects to issue a certificate or certificates to the Participant.

(d) At the time the Option is exercised, in whole or in part, or at the time some or all of the 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 shares of 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 Participant.

10. Withdrawal. Subject to applicable securities law restrictions and the Company’s policies (e.g., the Company’s insider trading policy), a Participant may withdraw all but not less than all the payroll deductions credited to his or her Account and not yet used to exercise his or her Option under the Plan at least five (5) days prior to the Exercise Date by giving a written Notice of Withdrawal to the Company or the Designated Agent in the form of Exhibit B to this Plan. All of the Participant’s payroll deductions credited to his or her Account shall be paid to such Participant as soon as practicable after receipt of the Notice of Withdrawal and such Participant’s Option for the Offering Period shall be automatically terminated, and no further payroll deductions for the purchase of shares shall be made for such Offering Period. If a

8

Participant withdraws from an Offering Period, payroll deductions shall not resume at the beginning of the succeeding Offering Period unless the Participant delivers to the Company a new Subscription Agreement. 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 or in succeeding Offering Periods which commence after the termination of the Offering Period from which the Participant withdraws.

11. Termination of Employment. Termination of a Participant’s employment for any reason, including retirement, death or the failure of a Participant to remain an Eligible Employee of the Company or of a Designated Subsidiary, immediately terminates his or her participation in this Plan. In such event, the payroll deductions credited to the Participant’s Account during the Offering Period but not yet used to purchase shares under the Plan will be returned without interest to him or her or, in the case of his or her death, to the person or persons entitled thereto under Section 13 hereof. For purposes of this Section 11, an employee will not be deemed to have terminated employment or failed to remain in the continuous employ of the Company or of a Designated Subsidiary in the case of sick leave, military leave, or any other leave of absence approved by the Board; provided that such leave is for a period of not more than ninety (90) days or reemployment upon the expiration of such leave is guaranteed by contract or statute.

12. Shares Reserved; Maximum Shares Subject to Option.

(a) Subject to adjustment upon changes in capitalization of the Company as provided in Section 17 hereof, the maximum number of shares of the Common Stock which may be acquired pursuant to Options under the Plan shall be two million (2,000,000) shares of Common Stock. Either shares issued heretofore or hereafter may be made subject to Options under the Plan. The shares of Common Stock that may be acquired pursuant to Options under the Plan shall be shares purchased by the Designated Agent on the open market; provided, however, that no more than the total number of shares of Common Stock as set forth above (as adjusted pursuant to Section 17 hereof), shall be acquired pursuant to Options under the Plan. If, for any reason, any Option under the Plan terminates in whole or in part, shares subject to such terminated Option may be again available pursuant to an Option under the Plan.

(b) Notwithstanding anything herein or in a Subscription Agreement to the contrary, the maximum number of shares of Common Stock that may be acquired by a Participant pursuant to an Option for each Offering Period is two thousand (2,000) shares of Common Stock.

(c) Until the shares of Common Stock 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.

(d) Shares to be delivered to a Participant under the Plan shall be registered in the name of the Participant or in the name of the Participant and his or her spouse.

9

13. Designation of Beneficiary.

(a) A Participant may file a written designation of a beneficiary who is to receive any shares of Common Stock and cash, 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 shares of Common Stock 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 exercise of the Option. For purposes of Section 423 and 421 of the Code, any shares (and, if applicable, cash in lieu of fractional shares) delivered to the Participant’s beneficiary shall be deemed to be transferred immediately to the Participant on the Participant’s death, and immediately thereafter, deemed to have been transferred by the Participant to the Participant’s beneficiary. If a Participant is married and the designated beneficiary is not the spouse, spousal consent shall be required for such designation to be effective. All beneficiary designations shall being such form and manner as the Administrator may designate from time to time.

(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 Participant’s surviving spouse, if any, or, if the Participant has no surviving spouse, 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 of Common Stock and/or cash to any one or more dependents or relatives of the Participant, or if dependent or relative is known to the Company, then to such other person as the Company may designate.

14. 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 13 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.

15. 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.

16. Reports. Individual Accounts shall be maintained for each Participant in the Plan. Statements of account shall be given to Participants 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.

10

17. Adjustments Upon Changes in Capitalization, Dissolution, Liquidation, or Change in Control.

(a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the maximum number of shares of Common Stock which shall be made available for sale under the Plan, the maximum number of shares of Common Stock each Participant may purchase pursuant to each Option, 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 in the event of any recapitalization, stock split, reverse stock split, rights offering, reorganization, merger, consolidation, split-up, spin-off, split-off, combination, subdivision, 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 affects the fair value of an Option. Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive, and shall be made in accordance with the rules of any securities exchange, stock market, or stock quotation system to which the Company is subject. 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. Notwithstanding the foregoing, no such adjustment shall be made or authorized to the extent that such adjustment would cause the Plan or any Option to violate Section 423 of the Code.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Offering Period then in progress shall be shortened by setting a new Exercise Date (the “New Exercise Date”), and shall terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date shall be before the date of the Company’s proposed dissolution or liquidation. The Administrator shall notify each Participant in writing, at least ten (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.

(c) Change in Control. In the event of a Change in 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 in Control. The Administrator shall notify each Participant in writing, at least ten (10) 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.

11

18. Amendment or Termination.

(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 stockholders. Except as provided in Section 17 and this Section 18, no amendment may make any change in any Option previously granted which adversely affects the rights of any Participant, unless their consent is obtained. In addition, to the extent the Administrator considers it necessary to comply with Rule 16b-3 under the Exchange Act, Section 423 of the Code, or any other applicable law, regulation or stock exchange rule, the Company shall obtain stockholder approval of any amendment in such a manner and to such a degree as required.

(b) Without stockholder approval 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 in accordance with Section 5, limit the frequency and/or number of changes in the amount withheld during an Offering Period, 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 by establishing a new Exercise Date, including an Offering Period underway at the time of the Board action; and

(iii) allocating shares of Common Stock.

Such modifications or amendments shall not require stockholder approval or the consent of any Participants.

19. 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.

12
