 Notwithstanding the foregoing or any other provision of this Plan, the definition of

Board deems reliable.

Stock Awards and the number of shares subject to such Stock Awards with respect to Initial and Annual Grants, as set forth in Section 6(c). 
 (b) Powers of Board. The Board shall have the power, subject to, and within the limitations of, the express provisions of the Plan: 
 (i) To determine the recipients and provisions of Stock Awards to the extent not specified in the Plan. 
 (ii) To construe and interpret the Plan and Stock Awards granted under it, and to establish, amend and revoke rules and regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or
inconsistency in the Plan or in any Stock Award Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective. 
 (iii) To amend the Plan or a Stock Award as provided in Section 13. 
 (iv) Generally, to
exercise such powers and to perform such acts as the Board deems necessary or expedient to promote the best interests of the Company that are not in conflict with the provisions of the Plan. 
 (c) Effect of Board’s Decision. All determinations, interpretations and constructions made by the Board in good faith shall not be
subject to review by any person and shall be final, binding and conclusive on all persons. 
  

	4.	SHARES SUBJECT TO THE PLAN. 

 (a) Share Reserve. Subject to the provisions of Section 12 relating to adjustments upon changes in the Class A Common Stock, the
Class A Common Stock that may be issued pursuant to Stock Awards shall not exceed in the aggregate One Million Two Hundred Fifty Thousand (1,250,000) shares of Class A Common Stock. Effective as of June 16, 2006, subject to
Section 4(b), the number of shares available for issuance under the Plan shall be reduced by: (i) one (1) share for each share of Class A Common Stock issued pursuant to an Option granted under Section 7 or a Stock
Appreciation Right granted under Section 8(c); and (ii) two (2) shares for each share of Class A Common Stock issued pursuant to a Restricted Stock Award granted under Section 8(a) or a Restricted Stock Unit Award granted
under Section 8(b). Shares may be 

  

 6 

 
issued in connection with a merger or acquisition as permitted by NYSE Listed Company Manual Section 303A.08 or, if applicable, NASD Rule
4350(i)(1)(A)(iii) or AMEX Company Guide Section 711 and such issuance shall not reduce the number of shares available for issuance under the Plan. 
 (b) Reversion of Shares to the Share Reserve. 
 (i) Shares Available For Subsequent
Issuance. If any Stock Award shall for any reason expire or otherwise terminate, in whole or in part, without having been exercised in full, or if any shares of Class A Common Stock issued to a Participant pursuant to a Stock Award are
forfeited back to or repurchased by the Company because of or in connection with the failure to meet a contingency or condition required to vest such shares in the Participant, the shares of Class A Common Stock not acquired, forfeited or
repurchased under such Stock Award shall revert to and again become available for issuance under the Plan. 
 (ii) Other Shares Available
for Subsequent Issuance. If any shares subject to a Stock Award are not delivered to a Participant because the Stock Award is exercised through a reduction of shares subject to the Stock Award (i.e., “net exercised”) or an
appreciation distribution in respect of a Stock Appreciation Right is paid in shares of Class A Common Stock, the number of shares subject to the Stock Award that are not delivered to the Participant shall remain available for subsequent
issuance under the Plan. If any shares subject to a Stock Award are not delivered to a Participant because such shares are withheld in satisfaction of the withholding of taxes incurred in connection with the exercise of an Option, Stock Appreciation
Right, or the issuance of shares under a Restricted Stock Award or Restricted Stock Unit Award, the number of shares that are not delivered to the Participant shall remain available for subsequent issuance under the Plan. If the exercise price of
any Stock Award is satisfied by tendering shares of Class A Common Stock held by the Participant (either by actual delivery or attestation), then the number of shares so tendered shall remain available for subsequent issuance under the Plan.

 To the extent there is issued a share of Class A Common Stock pursuant to a Stock Award that counted as two (2) shares against
the number of shares available for issuance under the Plan pursuant to Section 4(a) and such share of Common Stock again becomes available for issuance under the Plan pursuant to this Section 4(b), then the number of shares of Class A
Common Stock available for issuance under the Plan shall increase by two (2) shares. 
 (c) Source of Shares. The shares
of Class A Common Stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. If the aggregate number of shares of Class A Common Stock issuable as Initial and Annual Grants pursuant to
Sections 6(a) and 6(b) would exceed the number of shares remaining in the share reserve under Section 4(a) at such time of grant, then, in the absence of any Board action otherwise, a pro rata allocation of the shares of Class A Common
Stock available shall be made in as nearly a uniform manner as shall be practicable and equitable. 
  

 7 

	5.	ELIGIBILITY. 

 The Initial and Annual
Grants as set forth in Sections 6(a) and 6(b) automatically shall be granted under the Plan to all Non-Employee Directors. Stock Awards may also be granted as discretionary grants as set forth in Section 6(f). 
  

	6.	NON-DISCRETIONARY AND DISCRETIONARY GRANTS. 

 (a) Initial Grants. Without any further action of the Board, (i) each person who is or becomes a Non-Employee Director as of the
Effective Date, and (ii) each person who, after the Effective Date, is elected or appointed for the first time to be a Non-Employee Director automatically shall, upon the Effective Date or the date of his or her initial election or appointment
to be a Non-Employee Director, as applicable, be granted an Initial Grant as described in Section 6(c) below. 
 (b) Annual
Grants. Without any further action of the Board, on each July 1 (“Annual Grant Date”), commencing on July 1, 2004, each person who is then a Non-Employee Director, automatically shall be granted an Annual Grant
as described in Section 6(c) below; provided, however, that if a Non-Employee Director holds the position of Chairman of the Board on such date, such Non-Employee Director shall instead be granted an Annual Grant as described in
Section 6(c) below; further provided, however, that the number of shares subject to an Annual Grant for a particular Non-Employee Director shall be reduced, on a pro rata basis, for each month such person did not serve as a Non-Employee
Director during the twelve-month period from the prior Annual Grant Date (or from July 1, 2002 with respect to the first Annual Grant hereunder) until the current Annual Grant Date. 
 (c) Determination of Form of Initial and Annual Grants. On or before December 31 of any calendar year, the Board shall determine if
all Initial and Annual Grants to be granted in the subsequent calendar year shall be in the form of Options described in Section 7, Restricted Stock Awards described in Section 8(a), Restricted Stock Unit Awards described in
Section 8(b), Stock Appreciation Rights described in Section 8(c), or Performance Stock Awards described in Section 8(d). If the Board does not make such a determination on or before December 31 of a calendar year, all Initial
and Annual Grants to be granted in the subsequent calendar year shall be in the form of Options described in Section 7. 
 (d)
Initial and Annual Grants as Options. 
 (i) Initial Grant. If the Initial Grant is in the form of an Option, the Initial
Grant shall be a Nonstatutory Stock Option to purchase Thirty Thousand (30,000) shares of Class A Common Stock on the terms and conditions set forth herein. 
 (ii) Annual Grant. Subject to Section 6(b), if the Annual Grant is in the form of an Option, the Annual Grant shall be a Nonstatutory Stock Option to purchase Fifteen Thousand (15,000) shares
of Class A Common Stock on the terms and conditions set forth herein; provided, however, that if a Non-Employee Director holds the position of Chairman of the Board on the Annual Grant Date, such Non-Employee Director shall instead be
granted an Annual Grant to purchase Twenty-Five Thousand (25,000) shares of Class A Common Stock on the terms and conditions set forth herein. 
  

 8 

 (e) Initial and Annual Grants as Other Types of Stock Awards. If the Initial or Annual
Grant is in the form of a Restricted Stock Award, Restricted Stock Unit Award, Stock Appreciation Right or Performance Stock Award, the number of shares of Class A Common Stock subject to such Initial or Annual Grant shall be determined by the
Board in its sole discretion. 
 (f) Discretionary Grants. In addition to non-discretionary grants pursuant to Sections 6(a)
through 6(e), the Board, in its sole discretion, may grant Stock Awards to one or more Non-Employee Directors in such numbers and subject to such other provisions as it shall determine. The numbers and other provisions of such Stock Awards need not
be identical. 
  

	7.	OPTION PROVISIONS. 

 Each Option shall be in such form and shall contain such terms and conditions as required by the Plan. Each Option shall contain such additional terms and conditions, not inconsistent with the Plan, as the Board shall deem appropriate. Each
Option shall include (through incorporation of provisions hereof by reference in the Option or otherwise) the substance of each of the following provisions: 
 (a) Term. No Option shall be exercisable after the expiration of ten (10) years from the date it was granted. 
 (b) Exercise Price. The exercise price of each Option shall be one hundred percent (100%) of the Fair Market Value of the stock subject to the Option on the date the Option is granted.
Notwithstanding the foregoing, an Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the
provisions of Section 424(a) of the Code. 
 (c) Consideration. The purchase price of Class A Common Stock acquired
pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations and as determined by the Board in its sole discretion, by any combination of the methods of payment set forth below. The Board shall have the
authority to grant Options that do not permit all of the following methods of payment (or otherwise restrict the ability to use certain methods) and to grant Options that require the consent of the Company to utilize a particular method of payment.
The methods of payment permitted by this Section 7(c) are: 
 (i) by cash, check, bank draft or money order payable to the
Company; 
 (ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the
issuance of the stock subject to the Option, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds; 
 (iii) by delivery to the Company (either by actual delivery or attestation) of shares of Class A Common Stock; 
  

 9 

 (iv) by a “net exercise” arrangement pursuant to which the Company will reduce the
number of shares of Class A Common Stock issued upon exercise by the largest whole number of shares with a Fair Market Value that does not exceed the aggregate exercise price; provided, however, that the Company shall accept a cash or
other payment from the Participant to the extent of any remaining balance of the aggregate exercise price not satisfied by such reduction in the number of whole shares to be issued; provided, further, that shares of Class A Common Stock
will no longer be outstanding under an Option and will not be exercisable thereafter to the extent that (A) shares are used to pay the exercise price pursuant to the “net exercise,” (B) shares are delivered to the Participant as
a result of such exercise, and (C) shares are withheld to satisfy tax withholding obligations; or 
 (v) in any other form of
legal consideration that may be acceptable to the Board. 
 Unless otherwise specifically provided in the Option, the purchase price of
Class A Common Stock acquired pursuant to an Option that is paid by delivery to the Company of other Class A Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Class A Common Stock of
the Company that have been held for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). At any time that the Company is incorporated in Delaware, payment
of the Class A Common Stock’s “par value,” as defined in the Delaware General Corporation Law, shall not be made by deferred payment. 
 (d) Transferability. An Option is transferable by will or by the laws of descent and distribution. An Option also may be transferable upon written consent of the Company if, at the time of transfer, a
Form S-8 registration statement under the Securities Act is available for the exercise of the Option and the subsequent resale of the underlying securities. In addition, an Optionholder may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option. 
 (e) Vesting. Options shall vest as follows: 
 (i) Initial Grants:
1/36th of the shares of Class A Common Stock covered by an Initial Grant shall
vest monthly over thirty-six (36) months. 
 (ii) Annual Grants: 1/36th of the shares of Class A Common Stock covered by an Annual Grant shall vest monthly over thirty-six
(36) months. 
 (iii) Discretionary Grants: At the time of grant of an Option pursuant to Section 6(f), the Board may impose
such restrictions or conditions to the vesting of the Options as it, in its sole discretion, deems appropriate. 
 (f) Early
Exercise. The Option may, but need not, include a provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Class A
Common Stock subject to the Option prior to the full vesting of the Option. Any unvested shares of Class A Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines
to be appropriate. 
  

 10 

 (g) Termination of Continuous Service. In the event an Optionholder’s Continuous
Service terminates (other than upon the Optionholder’s death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise it as of the date of termination) but only within such
period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionholder’s Continuous Service, or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If,
after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. 
 (h) Extension of Termination Date. If the exercise of the Option following the termination of the Optionholder’s Continuous Service (other than upon the Optionholder’s death or Disability)
would be prohibited at any time solely because the issuance of shares would violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth
in Section 7(a) or (ii) the expiration of a period of three (3) months after the termination of the Optionholder’s Continuous Service during which the exercise of the Option would not be in violation of such registration
requirements. 
 (i) Disability of Optionholder. In the event an Optionholder’s Continuous Service terminates as a result
of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise it as of the date of termination), but only within such period of time ending on the earlier of
(i) the date six (6) months following such termination or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time
specified herein, the Option shall terminate. 
 (j) Death of Optionholder. In the event (i) an Optionholder’s
Continuous Service terminates as a result of the Optionholder’s death or (ii) the Optionholder dies within the three-month period after the termination of the Optionholder’s Continuous Service for a reason other than death, then the
Option may be exercised (to the extent the Optionholder was entitled to exercise the Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the Option upon the Optionholder’s death, but only within the period ending on the earlier of (1) the date six (6) months following the date of death or (2) the expiration of the term of such Option
as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate. 
  

	8.	PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

 (a) Restricted Stock Awards. Each Restricted Stock Award Agreement shall be in such form and shall contain
such terms and conditions as the Board shall deem appropriate. To the extent consistent with the Company’s Bylaws, at the Board’s election, shares of Class A Common Stock may be (x) held in book entry form subject to the
Company’s instructions until any restrictions relating to the Restricted Stock Award lapse; or (y) evidenced by a certificate, 

  

 11 

 
which certificate shall be held in such form and manner as determined by the Board. The terms and conditions of Restricted Stock Award Agreements may change
from time to time, and the terms and conditions of separate Restricted Stock Award Agreements need not be identical, provided, however, that each Restricted Stock Award Agreement shall include (through incorporation of provisions hereof by
reference in the agreement or otherwise) the substance of each of the following provisions: 
 (i) Consideration. A Restricted
Stock Award may be awarded in consideration for (A) past or future services actually or to be rendered to the Company or an Affiliate, or (B) any other form of legal consideration that may be acceptable to the Board in its sole discretion
and permissible under applicable law. 
 (ii) Vesting. Shares of Class A Common Stock awarded under a Restricted Stock
Award Agreement may be subject to forfeiture to the Company in accordance with a vesting schedule to be determined by the Board. 
 (iii) Termination of Participant’s Continuous Service. In the event a Participant’s Continuous Service terminates, the Company may receive pursuant to a forfeiture condition, any or all of the shares of Class A
Common Stock held by the Participant which have not vested as of the date of termination of Continuous Service under the terms of the Restricted Stock Award Agreement. 
 (iv) Transferability. Rights to acquire shares of Class A Common Stock under a Restricted Stock Award Agreement shall be transferable by the Participant only upon such terms and conditions as are
set forth in the Restricted Stock Award Agreement, as the Board shall determine in its sole discretion, so long as Class A Common Stock awarded under the Restricted Stock Award Agreement remains subject to the terms of the Restricted Stock
Award Agreement. 
 (b) Restricted Stock Unit Awards. Each Restricted Stock Unit Award Agreement shall be in such form and
shall contain such terms and conditions as the Board shall deem appropriate. The terms and conditions of Restricted Stock Unit Award Agreements may change from time to time, and the terms and conditions of separate Restricted Stock Unit Award
Agreements need not be identical, provided, however, that each Restricted Stock Unit Award Agreement shall include (through incorporation of the provisions hereof by reference in the Agreement or otherwise) the substance of each of the
following provisions: 
 (i) Consideration. At the time of grant of a Restricted Stock Unit Award, the Board will determine the
consideration, if any, to be paid by the Participant upon delivery of each share of Class A Common Stock subject to the Restricted Stock Unit Award. The consideration to be paid (if any) by the Participant for each share of Class A Common
Stock subject to a Restricted Stock Unit Award may be paid in any form of legal consideration that may be acceptable to the Board in its sole discretion and permissible under applicable law. 
 (ii) Vesting. At the time of the grant of a Restricted Stock Unit Award, the Board may impose such restrictions or conditions to the vesting
of the Restricted Stock Unit Award as it, in its sole discretion, deems appropriate. 
  

 12 

 (iii) Payment. A Restricted Stock Unit Award may be settled by the delivery of shares of
Class A Common Stock, their cash equivalent, any combination thereof or in any other form of consideration, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. 
 (iv) Additional Restrictions. At the time of the grant of a Restricted Stock Unit Award, the Board, as it deems appropriate, may impose such
restrictions or conditions that delay the delivery of the shares of Class A Common Stock (or their cash equivalent) subject to a Restricted Stock Unit Award to a time after the vesting of such Restricted Stock Unit Award. 
 (v) Dividend Equivalents. Dividend equivalents may be credited in respect of shares of Class A Common Stock covered by a Restricted
Stock Unit Award, as determined by the Board and contained in the Restricted Stock Unit Award Agreement. At the sole discretion of the Board, such dividend equivalents may be converted into additional shares of Class A Common Stock covered by
the Restricted Stock Unit Award in such manner as determined by the Board. Any additional shares covered by the Restricted Stock Unit Award credited by reason of such dividend equivalents will be subject to all the terms and conditions of the
underlying Restricted Stock Unit Award Agreement to which they relate. 
 (vi) Termination of Participant’s Continuous Service.
Except as otherwise provided in the applicable Restricted Stock Unit Award Agreement, such portion of the Restricted Stock Unit Award that has not vested will be forfeited upon the Participant’s termination of Continuous Service. 
 (vii) Compliance with Section 409A of the Code. Notwithstanding anything to the contrary set forth herein, any Restricted Stock Unit
Award granted under the Plan that is not exempt from the requirements of Section 409A of the Code shall contain such provisions so that such Restricted Stock Unit Award will comply with the requirements of Section 409A of the Code. Such
restrictions, if any, shall be determined by the Board and contained in the Restricted Stock Unit Award Agreement evidencing such Restricted Stock Unit Award. For example, such restrictions may include, without limitation, a requirement that any
Class A Common Stock that is to be issued in a year following the year in which the Restricted Stock Unit Award vests must be issued in accordance with a fixed pre-determined schedule. 
 (c) Stock Appreciation Rights. Each Stock Appreciation Right Agreement shall be in such form and shall contain such terms and conditions as the
Board shall deem appropriate. Stock Appreciation Rights may be granted as stand-alone Stock Awards or in tandem with other Stock Awards. The terms and conditions of Stock Appreciation Right Agreements may change from time to time, and the terms and
conditions of separate Stock Appreciation Right Agreements need not be identical; provided, however, that each Stock Appreciation Right Agreement shall include (through incorporation of the provisions hereof by reference in the Agreement or
otherwise) the substance of each of the following provisions: 
 (i) Term. No Stock Appreciation Right shall be exercisable
after the expiration of ten (10) years from the date of its grant or such shorter period specified in the Stock Appreciation Right Agreement. 
  

 13 

 (ii) Strike Price. Each Stock Appreciation Right will be denominated in shares of
Class A Common Stock equivalents. The strike price of each Stock Appreciation Right shall not be less than one hundred percent (100%) of the Fair Market Value of the Class A Common Stock equivalents subject to the Stock Appreciation
Right on the date of grant. 
 (iii) Calculation of Appreciation. The appreciation distribution payable on the exercise of a
Stock Appreciation Right will be not greater than an amount equal to the excess of (A) the aggregate Fair Market Value (on the date of the exercise of the Stock Appreciation Right) of a number of shares of Class A Common Stock equal to the
number of shares of Class A Common Stock equivalents in which the Participant is vested under such Stock Appreciation Right, and with respect to which the Participant is exercising the Stock Appreciation Right on such date, over (B) the
strike price that will be determined by the Board at the time of grant of the Stock Appreciation Right. 
 (iv) Vesting. At the
time of the grant of a Stock Appreciation Right, the Board may impose such restrictions or conditions to the vesting of such Stock Appreciation Right as it, in its sole discretion, deems appropriate. 
 (v) Exercise. To exercise any outstanding Stock Appreciation Right, the Participant must provide written notice of exercise to the Company
in compliance with the provisions of the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 
 (vi)
Payment. The appreciation distribution in respect of a Stock Appreciation Right may be paid in Class A Common Stock, in cash, in any combination of the two or in any other form of consideration, as determined by the Board and contained
in the Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. 
 (vii) Termination of Continuous Service.
In the event that a Participant’s Continuous Service terminates, the Participant may exercise his or her Stock Appreciation Right (to the extent that the Participant was entitled to exercise such Stock Appreciation Right as of the date of
termination) but only within such period of time ending on the earlier of (A) the date three (3) months following the termination of the Participant’s Continuous Service (or such longer or shorter period specified in the Stock
Appreciation Right Agreement), or (B) the expiration of the term of the Stock Appreciation Right as set forth in the Stock Appreciation Right Agreement. If, after termination, the Participant does not exercise his or her Stock Appreciation
Right within the time specified herein or in the Stock Appreciation Right Agreement (as applicable), the Stock Appreciation Right shall terminate. 
 (viii) Compliance with Section 409A of the Code. Notwithstanding anything to the contrary set forth herein, any Stock Appreciation Rights granted under the Plan that are not exempt from the requirements of
Section 409A of the Code shall contain such provisions so that such Stock Appreciation Rights will comply with the requirements of Section 409A of the Code. Such restrictions, if any, shall be determined by the Board and contained in the
Stock Appreciation Right Agreement evidencing such Stock Appreciation Right. For example, such restrictions may include, without limitation, a requirement that a Stock Appreciation Right that is to be paid wholly or partly in cash must be exercised
and paid in accordance with a fixed pre-determined schedule. 
  

 14 

 (d) Performance Stock Awards. A Performance Stock Award is a Stock Award that may be
granted, may vest, or may be exercised based upon the attainment during one or more periods of time of certain performance goals. Such performance goals may be determined by the Board in its sole discretion or may be based on the Performance Goals
selected by the Committee under the Company’s 2002 Equity Incentive Plan (as such terms are defined in the Company’s 2002 Equity Incentive Plan). A Performance Stock Award may, but need not, require the completion of a specified period of
Continuous Service. The length of any performance period, the performance goals to be achieved during such performance period, and the measure of whether and to what degree such performance goals have been attained shall be conclusively determined
by the Board in its sole discretion. In addition, to the extent permitted by applicable law and the applicable Award Agreement, the Board may determine that cash may be used in payment of Performance Stock Awards. 
  

	9.	COVENANTS OF THE COMPANY. 

 (a) Availability of Shares. During the terms of the Stock Awards, the Company shall keep available at all times the number of shares of
Class A Common Stock required to satisfy such Stock Awards. 
 (b) Securities Law Compliance. The Company shall seek to
obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Class A Common Stock upon exercise of the Stock Awards; provided,
however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any stock issued or issuable pursuant to any such Stock Award. If, after reasonable efforts, the Company is unable to
obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell
stock upon exercise of such Stock Awards unless and until such authority is obtained. 
  

	10.	USE OF PROCEEDS FROM STOCK. 

 Proceeds from the sale of stock pursuant to Stock Awards shall constitute general funds of the Company. 
  

	11.	MISCELLANEOUS. 

 (a)
Stockholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares subject to a Stock Award unless and until such Participant has satisfied all requirements for
exercise of the Stock Award pursuant to its terms. 
 (b) No Service Rights. Nothing in the Plan or any instrument executed or
Stock Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company as a Non-Employee Director or shall affect the right of the Company or an 

  

 15 

 
Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the service of a Consultant
pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state
in which the Company or the Affiliate is incorporated, as the case may be. 
 (c) Investment Assurances. The Company may
require a Participant, as a condition of exercising or acquiring stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters
and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (ii) to give written assurances satisfactory to the Company stating that the Participant is acquiring the stock subject to the Stock Award for the Participant’s own
account and not with any present intention of selling or otherwise distributing the stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares upon the
exercise or acquisition of stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act or (2) as to any particular requirement, a determination is made by counsel for the
Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems
necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock. 
 (d) Withholding Obligations. The Participant may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of stock under a Stock Award by any of the
following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment; (ii) authorizing the Company to withhold
shares from the shares of the Class A Common Stock otherwise issuable to the Participant as a result of the exercise or acquisition of stock under the Stock Award, provided, however, that no shares of Class A Common Stock are
withheld with a value exceeding the minimum amount of tax required to be withheld by law; or (iii) delivering to the Company owned and unencumbered shares of the Class A Common Stock. 
 (e) Lock-Up Period. Upon exercise of any Stock Award, a Participant may not sell, dispose of, transfer, make any short sale of, grant any
option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any shares of Class A Common Stock or other securities of the Company held by the Participant, for a period of time specified
by the managing underwriter(s) (not to exceed one hundred eighty (180) days) following the effective date of a registration statement of the Company filed under the Securities Act, other than a Form S-8 registration statement, (the “Lock
Up Period”); provided, however, that nothing contained in this section shall prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock Up Period. A Participant may be required to execute and deliver
such other agreements as may be reasonably requested by the Company and/or the underwriter(s) that are consistent with the foregoing or that are necessary to give further effect 

  

 16 

 
thereto. In order to enforce the foregoing, the Company may impose stop-transfer instructions with respect to such shares of Class A Common Stock until
the end of such period. The underwriters of the Company’s stock are intended third party beneficiaries of this Section 11(e) and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.

  

	12.	ADJUSTMENTS UPON CHANGES IN CLASS A COMMON STOCK.

 (a) Capitalization Adjustments. If any change is made in the stock subject to the Plan, or subject to any
Stock Award, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination
of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the Plan will be appropriately adjusted in the nature, class(es) and maximum number of securities subject
both to the Plan pursuant to Section 4 and to the nondiscretionary Stock Awards specified in Section 6, and the outstanding Stock Awards will be appropriately adjusted in the nature, class(es) and number of securities and price per share
of stock subject to such outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a
transaction “without receipt of consideration” by the Company.) 
 (b) Dissolution or Liquidation. In the event of a
dissolution or liquidation of the Company, then all outstanding Stock Awards shall terminate immediately prior to such event. 
 (c)
Change in Control. If a Change in Control occurs and as of, or within twelve (12) months after, the effective time of such Change in Control, a Participant’s Continuous Service terminates, then his or her Stock Awards will
accelerate and become fully vested and immediately exercisable (to the extent applicable), unless the termination was a result of the Participant’s resignation (other than any resignation contemplated by the terms of the Change in Control or
required by the Company or the acquiring entity pursuant to the Change in Control). 
 (d) Parachute Payments. In the event
that the acceleration of the vesting and exercisability of the Stock Awards provided for in Section 12(c) and benefits otherwise payable to a Participant (“Payment”) would (i) constitute a “parachute payment” within the
meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The
“Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment,
whichever amount, after taking into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in the Participant’s receipt, on an after-tax
basis, of the greater amount of the Payment notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment
equals the Reduced Amount, reduction shall occur in the following order unless the Participant elects in writing a different order (provided, however, that such election shall be subject to Company approval if made on or 

  

 17 

 
after the effective date of the event that triggers the Payment): reduction of cash payments; cancellation of accelerated vesting of Stock Awards; reduction
of employee benefits. In the event that acceleration of vesting of Stock Award compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of the Participant’s Stock Awards
(i.e., earliest granted Stock Award cancelled last) unless the Participant elects in writing a different order for cancellation. 
 The accounting firm engaged by the Company for general audit purposes as of the day prior to the effective date of the Change in Control shall perform the foregoing calculations. If the accounting firm so engaged by the Company is serving
as accountant or auditor for the individual, entity or group effecting the Change in Control, the Company shall appoint a nationally recognized accounting firm to make the determinations required hereunder. The Company shall bear all expenses with
respect to the determinations by such accounting firm required to be made hereunder. 
 The accounting firm engaged to make the
determinations hereunder shall provide its calculations, together with detailed supporting documentation, to the Participant and the Company within fifteen (15) calendar days after the date on which the Participant’s right to a Payment is
triggered (if requested at that time by the Participant or the Company) or such other time as requested by the Participant or the Company. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or
after the application of the Reduced Amount, it shall furnish the Participant and the Company with an opinion reasonably acceptable to the Participant that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of
the accounting firm made hereunder shall be final, binding and conclusive upon the Participant and the Company. 
  

	13.	AMENDMENT OF THE PLAN AND STOCK AWARDS. 

 (a) Amendment of Plan. The Board at any time, and from time to time, may amend the Plan. However, except as provided in Section 12
relating to adjustments upon changes in Class A Common Stock, no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy the requirements of Rule 16b-3 or any
Nasdaq or securities exchange listing requirements. 
 (b) Stockholder Approval. The Board may, in its sole discretion, submit
any other amendment to the Plan for stockholder approval. 
 (c) No Impairment of Rights. Rights under any Stock Award granted
before amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 
 (d) Amendment of Stock Awards. The Board at any time, and from time to time, may amend the terms of any one or more Stock Awards;
provided, however, that the rights under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing. 
  

 18 

	14.	TERMINATION OR SUSPENSION OF THE PLAN. 

 (a) Plan Term. The Board may suspend or terminate the Plan at any time. No Stock Awards may be granted under the Plan while the Plan is
suspended or after it is terminated. 
 (b) No Impairment of Rights. Suspension or termination of the Plan shall not impair
rights and obligations under any Stock Award granted while the Plan is in effect except with the written consent of the Participant. 
  

	15.	EFFECTIVE DATE OF PLAN. 

 The Plan shall become effective on the date the Plan is adopted by the Board, but no Stock Award shall be exercised unless and until the Plan has been
approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board. 
  

	16.	CHOICE OF LAW. 

 All questions concerning the construction, validity and interpretation of this Plan shall be governed by the law of the State of Delaware, without regard to such state’s conflict of laws rules.
