Employees’ behalf following purchases of Common Stock under the Plan. The Committee shall have full power and authority to administer the Plan, to interpret and construe any provision of the Plan finally and conclusively with respect to all
persons having any interest thereunder, to adopt rules and regulations not inconsistent with the Plan for carrying out the Plan, providing for matters not specifically covered thereby, and to alter, amend or revoke any rules or regulations so
adopted; provided, however, that the Administration Agent shall have the responsibilities with respect to the Plan set forth herein. No member of the Committee shall be liable to the Company, any stockholder, any employee of the Company or its
subsidiaries or any participant in the Plan for any action or determination in good faith with respect to the Plan. 
 3.2 ADMINISTRATION AGENT. The Committee will select and designate a third-party administration firm to provide the administrative and brokerage services, respectively, with respect to the Plan as set forth herein. The Committee may
from time to time replace and redesignate the Administration Agent. 
 ARTICLE IV 
 SHARES SUBJECT TO PLAN 
 4.1 SHARES SUBJECT TO PLAN. The Company hereby reserves 5,000,000 shares of Common Stock for issuance under the Plan less the amount of shares previously issued under any predecessor plans. These shares shall be authorized and unissued
shares. To the extent provided by resolution of the Board, such shares may be uncertificated. 
 4.2 ADJUSTMENTS TO SHARES RESERVED. In
the event of any merger, consolidation, reorganization, recapitalization, spin-off, stock dividend, stock split, reverse stock split, exchange or other distribution with respect to shares of Common Stock or other change in the corporate structure or
capitalization affecting the Common Stock, the type and number of shares of stock which are or may be subject to the Plan or contributed amounts under the Plan shall be equitably adjusted by the Committee, in its sole discretion, to preserve the
value of benefits under the Plan. 
 ARTICLE V 
 ELIGIBILITY AND ENROLLMENT 
 5.1 INITIAL ELIGIBILITY. Subject to the limitations set forth
below, every Employee of the Company and its subsidiaries is eligible to participate in the Plan upon his or her Employment Commencement Date, or anytime thereafter, provided he or she has completed the requisite requirements for enrollment as set
forth in Section 5.3 of the Plan. 
 5.2 LIMITATIONS ON PARTICIPATION. Notwithstanding any provisions of the Plan to the contrary,
no Employee shall be entitled to participate, select a Contribution Rate, contribute amounts to his or her Contribution Account or otherwise purchase Common Stock under the Plan (or any other employee stock purchase plan of the Company and its
subsidiaries, if any) to the extent: 







 (a) that such participation, contribution or purchase, as the case may be, is at a
rate that exceeds $25,000 in fair market value of the Common Stock in any calendar year (as determined under Section 423 of the Code); or 
 (b) that, giving effect to such participation, contribution or purchase, as the case may be, such Employee would own or beneficially own Common Stock possessing five percent or more of the total combined voting
power or value of all classes of stock of the Company. 
 5.3 ENROLLMENT. The Company or the Administration Agent shall furnish
information relating to the Plan and Plan enrollment to each Employee upon such Employee’s Employment Commencement Date, or with respect to current Employees who are not participants in the Plan, upon their request. If the Employee elects to
participate in the Plan (and thus becomes a Participating Employee), he or she shall enroll according to the enrollment procedures set forth in the information provided by the Company or the Administration Agent. Upon enrollment, the Company or the
Administration Agent will provide a confirmation statement to the Participating Employee as soon as administratively practicable. If an eligible Employee does not elect to participate in the Plan immediately following his or her Employment
Commencement Date, such Employee may nonetheless elect to participate at a later date commencing with the most administratively practicable subsequent payroll period after all enrollment procedures have been satisfied. 
 5.4 EFFECTS OF ENROLLMENT. Except as set forth elsewhere in this Plan, enrollment in the Plan is for the Employee Plan Period commencing on an
Employee’s Effective Date. Except as set forth elsewhere in this Plan, amounts contributed by the Participating Employee will be applied to the purchase of shares of Common Stock in accordance with the provisions of Article VII at the end
of such Employee Plan Period. Enrollment continues, and is automatically renewed at the end of an Employee Plan Period for an additional Employee Plan Period, unless and until payroll deductions and Plan participation have been specifically
discontinued in accordance with the provisions of Article VI. 
 5.5 PARTICIPATING EMPLOYEE’S CONTRIBUTION RATE. In order to
participate in the Plan, an Employee must elect to participate in accordance with Section 5.3 and must authorize the Company or its subsidiary, as applicable, to deduct from payroll on behalf of such Participating Employee a specified amount
per Pay Period. Such amount may not be less than $5.00 nor more than $817.00 per pay period; provided, however, that such minimum and maximum amounts may be adjusted by the Company at any time and from time to time for the sake of administrative
convenience and/or to ensure continued compliance with the provisions of Section 423 of the Code. 
 ARTICLE VI 
 DEDUCTIONS, MODIFICATIONS & PLAN WITHDRAWAL 
 6.1 DEDUCTIONS. Payroll deductions at the Participating Employee’s Contribution Rate shall begin on the first Pay Period Date following the Effective Date of such Participating Employee’s enrollment in
the Plan. The Participating Employee’s contributions shall be allocated to and deemed a part of the Participating Employee’s Contribution Account. Participating Employee contributions will not be permitted to begin at any time other than
the first Pay Period Date in any Employee Plan Period. No interest shall accrue or be paid on any amounts withheld under the Plan. 
 6.2 MODIFICATIONS IN CONTRIBUTION RATE. The Participating Employee’s Contribution Rate, once established, shall remain in effect for all of the Employee Plan Period and subsequent Employee Plan Periods unless increased or
decreased by the Participating Employee in the manner specified by the Company or the Administration Agent. 
 6.3 SUSPENDING
CONTRIBUTIONS. At any time during an Employee Plan Period, a Participating Employee may notify the Company or the Administration Agent that he or she wishes to suspend his or her contributions for the current Employee Plan Period or for a period of
time extending beyond the current 








 
Employee Plan Period. This notice shall be communicated in the manner specified by the Company or the Administration Agent. A Participating Employee who
suspends contributions will have the already-contributed balance in his or her Contribution Account applied to purchases of Common Stock on the Purchase Date of the Employee Plan Period in which such suspension is effective. A Participating Employee
who has suspended contributions under the Plan may resume contributions in the Employee Plan Period immediately following the Employee Plan Period in which contributions were suspended, or in any subsequent Employee Plan Period thereafter, provided
that the Employee gives notice of the re-enrollment in the manner specified by the Company or Administration Agent. 
 ARTICLE VII

 PURCHASE OF COMMON STOCK 
 7.1 PURCHASES. On each Purchase Date, the funds in a Participating Employee’s Contribution Account shall be used to purchase the maximum number of shares of Common Stock determined by dividing the Issue Price into the balance in
such Contribution Account (subject to the limitations set forth in Section 7.2). 
 7.2 OVER-ALLOTMENTS. If the total number of
shares to be purchased by all Participating Employees on a Purchase Date exceeds the number of shares authorized under Article IV of the Plan, a pro-rata allocation of the available shares will be made among all Participating Employees based on
the amount of the balances in their respective Contribution Accounts through the Purchase Date. 
 7.3 ISSUED SHARES. A Participating
Employee’s shares of Common Stock will be deposited in a brokerage account, as soon as administratively feasible, opened on behalf of the Participating Employee with the Administration Agent. All fees and commissions associated with the
operation of such brokerage account shall be the responsibility of the Participating Employee. 
 ARTICLE VIII 
 CHANGES IN STATUS AFFECTING ELIGIBILITY 
 8.1 TERMINATION OF EMPLOYMENT. Effective upon the termination of the Participating Employee’s employment for any reason, including without limitation death, permanent disability, or retirement, such person’s participation in
the Plan shall be deemed permanently suspended, and the Company shall purchase shares of Common Stock with any authorized payroll deductions that are credited to his or her Contribution Account as of the Purchase Date for the Pay Period that the
termination of employment is effective. Notwithstanding the foregoing, with respect to the following described Participating Employees, upon the termination of employment of a Participating Employee arising in connection with (i) the Cessation
of Business of any business unit, division or company employing such Participating Employee, such Participating Employee shall be allowed to continue participating in the Plan up to such Cessation of Business and (ii) the Sale of Business of
any direct or indirect subsidiary of the Company, business unit, division or company, employing such Participating Employee, such person’s authorized payroll deductions credited to his or her Contribution Account through the closing date of the
Sale of Business shall be used to purchase shares pursuant to the terms of the Plan. 
 8.2 TEMPORARY ABSENCE. If a Participating
Employee temporarily leaves the employ of the Company or its subsidiaries by reason of leave of absence, the Participating Employee may continue to participate in the Plan as long as such Participating Employee continues to make contributions
through payroll deductions. If a Participating Employee is on unpaid leave, he or she will not be able to continue participating in the Plan. However, unless such Participating Employee withdraws from the Plan, Common Stock will be purchased on such
person’s behalf at the end of the Employee Plan Period with any amounts deducted from such Participating Employee’s paycheck during that Employee Plan Period. 







 ARTICLE IX 
 GENERAL PROVISIONS 
 9.1 TERM OF PLAN. The Plan shall remain in effect until all of the shares
of Common Stock reserved for issuance hereunder have been issued and balances maintained in the Participating Employee Contribution Accounts have been distributed, unless earlier terminated by the Board. 
 9.2 AMENDMENT OR TERMINATION BY COMMITTEE. The Committee may at any time or from time to time amend the Plan in any respect. The Committee may
terminate the Plan at any time. If the Plan is terminated, unless otherwise specified, the date of termination shall be treated as a Purchase Date. All funds in Participating Employee Contribution Accounts as of the termination date which are not
applied toward purchases of shares of Common Stock shall be refunded to the Participating Employees as soon as administratively feasible. 
 9.3 TRANSFERABILITY. Neither the right of an Employee to purchase shares of Common Stock hereunder, nor such Participating Employee’s Contribution Account balance, may be transferred, pledged or assigned by the Employee (except,
in the event of the Employee’s death, by will or the laws of descent and distribution). Any such attempted transfer, pledge, assignment or other disposition shall be treated as an election of the Participating Employee to withdraw his or her
participation in the Plan. 
 9.4 COMPLIANCE WITH SECURITIES LAWS. Notwithstanding any other provision of the Plan, the Company shall
have no obligation to issue any shares of Common Stock under the Plan unless such issuance would comply with all applicable laws, including Federal and state securities laws, and the applicable regulations or requirements of any securities exchanges
or similar entities. 
 9.5 INVESTMENT INTENT. Prior to the issuance of any shares of Common Stock under the Plan, the Company may
require a written statement that the recipient is acquiring the shares for investment and not for the purpose or with the intention of distributing the shares and will not dispose of them in violation of the registration requirements of the
Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder. 
 9.6 COMPLIANCE WITH SECTION 16(b). With
respect to any person who is subject to Section 16(a) of the Securities Exchange Act of 1934, as amended, the Committee may, at any time, add such conditions and limitations respecting eligibility or participation under the Plan as it deems
necessary or desirable to comply with the requirements of Rule 16b-3 thereunder; provided, however, that any rights or privileges that are extended to such persons shall be extended uniformly to all eligible employees. 
 9.7 WITHHOLDING TAXES. Amounts withheld, shares issued and payments made pursuant to the Plan may be subject to withholding taxes, and the Company
and its subsidiaries shall have the right to withhold from any payment or distribution of shares or to collect as a condition of any payment or distribution under the Plan, as applicable, any taxes required by law to be withheld. 
 9.8 NO CONTINUED EMPLOYMENT. The Plan does not constitute a contract of employment or continued service, and participation in the Plan will not give
any Employee the right to be retained in the employ of the Company or any right or claim to any benefit under the Plan unless such right or claim has specifically accrued under the terms of the Plan. 
 9.9 TREATMENT AS STOCKHOLDER. Any contribution made by a Participating Employee under the Plan shall not create any rights in such Participating
Employee as a stockholder of the Company until shares of Common Stock are registered in the name of such person. 







 9.10 VOTING OF ISSUED SHARES. The Administration Agent will vote the Common Stock held in brokerage
accounts on behalf of Participating Employees in accordance with instructions received from such Participating Employees. The Administration Agent will transmit to Participating Employees all proxy material and other reports furnished by the Company
to its stockholders. 
 9.11 GOVERNING LAW. The law of the State of Delaware will govern all matters relating to this Plan except to the
extent it is superseded by the laws of the United States.
