then traded; or, if no such closing prices are reported, the mean between the high bid and low ask prices that day on the principal market or national quotation system on which such shares are then quoted; provided, however, that when appropriate,

any way preclude or restrict the right of the Company or any Related Corporation to discharge or dismiss any Recipient or other person in the Service of the Company or any Related Corporation for any other acts or omissions but such other acts or
omission shall not be deemed, for purposes of the Plan, to constitute grounds for Just Cause Dismissal.

compensation an Eligible Person will receive under any Incentive Award is not based solely on an increase in the value of Common Stock after the date of grant or award, the Administrator, in order to qualify an Incentive Award as performance-based
compensation under Section 162(m) of the Code and the regulations thereunder, can condition the grant, award, vesting, or exercisability of such an award on the attainment of a preestablished, objective performance goal. For this purpose, a
preestablished, objective performance goal may include one or more of the following performance criteria: (i) cash flow, (ii) earnings per share (including earnings before interest, taxes, and amortization), (iii) return on equity,

 The Board has adopted this Plan to advance the
interests of the Company and its stockholders by (a) providing Eligible Persons with financial incentives to promote the success of the Company’s business objectives, and to increase their proprietary interest in the success of the
Company, and (b) giving the Company a means to attract and retain Eligible Persons. 
 1.03 Common Stock Subject to the Plan.

 (a) Number of Shares. Subject to Section 1.05(b), the total number of shares of Common Stock initially
authorized for issuance pursuant to Awards granted hereunder shall be 9,600,000, provided that the total number of shares authorized for issuance hereunder shall be automatically increased to equal 10% of the number of shares of Common Stock issued
and outstanding as of the following measurement dates: January 1, 2011, May 1, 2011, September 1, 2011, January 1, 2012, May 1, 2012, September 1, 2012 and January 1, 2013, provided, further that in no event
shall the total number of shares issued hereunder exceed 170,000,000.

 (c) Availability of Unused Shares. Shares of Common Stock subject to unexercised portions of
any Award granted under this Plan that expire, terminate or are cancelled, and shares of Common Stock issued pursuant to an Award under this Plan that are reacquired by the Company pursuant to the terms of the Award under which such shares were

 5 








 (d) Grant Limits. Notwithstanding any other provision of this Plan, no Eligible
Person shall be granted Awards with respect to more than 20 million shares of Common Stock in the aggregate in any one calendar year; provided, however, that this limitation shall not apply if it is not required in order for the compensation
attributable to Awards hereunder to qualify as Performance-Based Compensation. 
 1.04 Administration of the Plan. 

(a) The Administrator. The Plan will be administered by a Committee, which will consist of two or more members of the Board
each of whom must be an “independent director” as defined by applicable listing standards. Notwithstanding the foregoing or any provision of the Plan to the contrary, the Board may, in lieu of the Committee, exercise any authority granted
to the Committee pursuant to the provisions of the Plan. To obtain the benefits of Rule 16b-3, Incentive Awards must be granted by the entire Board or a Committee comprised entirely of “non-employee directors” as such term is defined
in Rule 16b-3. In addition, if Incentive Awards are to be made to persons subject to Section 162(m) of the Code and such Awards are intended to constitute Performance-Based Compensation, then such Incentive Awards must be granted by a
Committee comprised entirely of “outside directors” as such term is defined in the regulations under Section 162(m) of the Code. 
 (b) Authority of the Administrator. The Administrator has authority in its discretion to select the Eligible Persons to whom, and the time or times at which, Incentive Awards shall be granted
or sold, the nature of each Incentive Award, the number of shares of Common Stock or the number of rights that make up or underlie each Incentive Award, the period for the exercise of each Incentive Award, the performance criteria (which need not be
identical) utilized to measure the value of Performance Awards, and such other terms and conditions applicable to each individual Incentive Award as the Administrator shall determine. In addition, the Administrator shall have all other powers
granted to it in the Plan. 
 (c) Interpretation. Subject to the express provisions of the Plan, the Administrator
has the authority to interpret the Plan and any Award Documents, to determine the terms and conditions of Incentive Awards and to make all other determinations necessary or advisable for the administration of the Plan. All interpretations,
determinations and actions by the Administrator shall be final, conclusive and binding upon all parties. The Administrator has authority to prescribe, amend and rescind rules and regulations relating to the Plan. 

(d) No Liability. The Administrator and its delegates shall be indemnified by the Company to the fullest extent provided for
in the Company’s certificate of incorporation and bylaws. 
 1.05 Other Provisions. 

(a) Documentation. Each Award granted under the Plan shall be evidenced by an Award Document which shall set forth the terms
and conditions applicable to the Award as the Administrator may in its discretion determine consistent with the Plan, provided that the Administrator shall exercise no discretion with respect to Nonemployee Directors’ Options, which shall
reflect only the terms of the Award as set forth in Article III and certain administrative matters dictated by the Plan. Award Documents shall comply with and be subject to the terms and conditions of the Plan. In case of any conflict between
the Plan and any Award Document, the Plan shall control. Various Award Documents covering the same types of Awards may but need not be identical. 
 (b) Adjustment Provisions. Should any change be made to the outstanding shares of Common Stock by reason of a merger, consolidation, reorganization, recapitalization, reclassification,
combination of shares, stock dividend, stock split, reverse stock split, exchange of shares or other change affecting the outstanding Common Stock without the Company’s receipt of consideration, an appropriate and proportionate adjustment may
be made in (i) the maximum number and kind of shares subject to the Plan as provided in Section 1.03, (ii) the number and kind of shares or other securities subject to then outstanding Awards, (iii) the price for each share or
other unit of any other securities subject to then outstanding Awards and (iv) the number and kind of shares or other securities subject to the Nonemployee Director Options described in Section 3.01 and 3.02. In addition, the per person
limitation set forth in Section 1.03(d) shall also be subject to adjustment as provided in this Section 1.05(b), but only to the extent such adjustment would not affect the status of compensation attributable to Awards hereunder as
Performance-Based Compensation. Such adjustments are to be effected in a manner that shall preclude the enlargement or dilution of rights and benefits under the Awards. In no event shall any adjustments be made in connection with the conversion of
preferred stock or warrants into shares of Common Stock. No fractional interests will be issued under the Plan resulting from any such adjustments. 

  
 6 








 (c) Continuation of Service. Nothing contained in this Plan (or in Award
Documents or in any other documents related to this Plan or to Awards granted hereunder) shall confer upon any Eligible Person or Recipient any right to continue in the Service of the Company or its Related Corporations or constitute any contract or
agreement of employment or engagement, or interfere in any way with the right of the Company or its Related Corporations to reduce such person’s compensation or other benefits or to terminate the Service of such Eligible Person or Recipient,
with or without cause. Except as expressly provided in the Plan or in any Award Document, the Company shall have the right to deal with each Recipient in the same manner as if the Plan and any Award Document did not exist, including, without
limitation, with respect to all matters related to the hiring, discharge, compensation and conditions of the employment or engagement of the Recipient. 
 (d) Restrictions. All Awards granted under the Plan shall be subject to the requirement that, if at any time the Company shall determine, in its discretion, that the listing, registration or
qualification of the shares subject to Awards granted under the Plan upon any securities exchange or under any state or federal law, or the consent or approval of any government regulatory body, is necessary or desirable as a condition of, or in
connection with, the granting of such an Award or the issuance, if any, or purchase of shares in connection therewith, such Award may not be exercised in whole or in part unless such listing, registration, qualification, consent or approval shall
have been effected or obtained free of any conditions not acceptable to the Company. 
 (e) Additional Conditions.
Any Incentive Award may also be subject to such other provisions (whether or not applicable to any other Award or Recipient) as the Administrator determines appropriate. 
 (f) Tax Withholding. The Company’s obligation to deliver shares of Common Stock under the Plan shall be subject to the satisfaction of all applicable income and employment tax withholding
requirements. 
 (g) Privileges of Stock Ownership. Except as otherwise set forth herein, a Holder shall have no
rights as a stockholder of the Company with respect to any shares issuable or issued in connection with the Award until the date of the receipt by the Company of all amounts payable in connection with exercise of the Award, performance by the Holder
of all obligations thereunder, and the Company issues a stock certificate representing the appropriate number of shares. Status as an Eligible Person shall not be construed as a commitment that any Incentive Award will be granted under this Plan to
an Eligible Person or to Eligible Persons generally. No person shall have any right, title or interest in any fund or in any specific asset (including shares of capital stock) of the Company by reason of any Award granted hereunder. Neither this
Plan (or any documents related hereto) nor any action taken pursuant hereto shall be construed to create a trust of any kind or a fiduciary relationship between the Company and any person. To the extent that any person acquires a right to receive an
Award hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company. 

(h) Effective Date and Duration of Plan; Amendment and Termination of Plan. The Plan shall become effective upon its approval
by the Company’s stockholders. Unless terminated by the Board prior to such time, the Plan shall continue in effect until the 10th anniversary of the date the Plan was adopted, whereupon the Plan shall terminate automatically. The Board may,
insofar as permitted by law, from time to time suspend or terminate the Plan. No Awards may be granted during any suspension of this Plan or after its termination. Any Award outstanding after the termination of the Plan shall remain in effect until
such Award has been exercised or expires in accordance with its terms and the terms of the Plan. The Board may, insofar as permitted by law, from time to time revise or amend the Plan in any respect except that no such amendment shall adversely
affect any rights or obligations of the Holder under any outstanding Award previously granted under the Plan without the consent of the Holder. Amendments shall be subject to stockholder approval to the extent such approval is required to comply
with the listing requirements imposed by any exchange or trading system upon which the Company’s securities trade or applicable law. 
 (i) Amendment of Awards. The Administrator may make any modifications in the terms and conditions of an outstanding Incentive Award, provided that (i) the resultant provisions are
permissible under the Plan and (ii) the consent of the Holder shall be obtained if the amendment will adversely affect his or her rights under the Award. However, the outstanding Options may not be repriced without stockholder approval.

 (j) Nonassignability. No Incentive Stock Option granted under the Plan shall be assignable or transferable except
by will or by the laws of descent and distribution. No other Awards granted under the Plan shall be assignable or transferable except (i) by will or by the laws of descent and distribution, (ii) to one or more of the Recipient’s
family members (as such term is defined in the instructions to Form S-8) or (iii) upon dissolution of marriage pursuant to a qualified domestic relations order. During the lifetime of a Recipient, an Award granted to him or her shall be
exercisable only by the Holder or his or her guardian or legal representative. 

  
 7 








 (k) Other Compensation Plans. The adoption of the Plan shall not affect any
other stock option, incentive or other compensation plans in effect for the Company, and the existence of the Plan shall not preclude the Company from establishing any other forms of incentive or other compensation for Eligible Persons. 

(l) Plan Binding on Successors. The Plan shall be binding upon the successors and assigns of the Company. 

(m) Participation by Foreign Employees. Notwithstanding anything to the contrary herein, the Administrator may, in order to
fulfill the purposes of the Plan, structure grants of Incentive Awards to Recipients who are foreign nationals or employed outside of the United States to recognize differences in applicable law, tax policy or local custom. 

ARTICLE II 

INCENTIVE AWARDS 

2.01 Grants of Incentive Awards. 
 Subject to the express provisions of this Plan, the Administrator may from time to time in its discretion select from the class of Eligible Persons those individuals to whom Incentive Awards may be
granted pursuant to its authority as set forth in Section 1.04(b). Each Incentive Award shall be subject to the terms and conditions of the Plan and such other terms and conditions established by the Administrator as are not inconsistent with
the provisions of the Plan. 
 2.02 Options. 
 (a) Nature of Options. The Administrator may grant Incentive Stock Options and Nonqualified Stock Options under the Plan. However, Incentive Stock Options may only be granted to Employees of
the Company or its Related Corporations. 
 (b) Option Price. The Exercise Price per share for each Option (other
than a Nonemployee Director’s Option) shall be determined by the Administrator at the date such Option is granted and shall not be less than the Fair Market Value of a share of Common Stock (or other securities, as applicable) on the date of
grant. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the option price of such Incentive Stock Option shall not be less than 110% of the Fair Market Value of a share of Common Stock (or other securities, as
applicable). Notwithstanding the foregoing, however, in no event shall the Exercise Price be less than the par value of the shares of Common Stock. 
 (c) Option Period and Vesting. Options (other than Nonemployee Directors’ Options) hereunder shall vest and may be exercised as determined by the Administrator, except that exercise of
such Options after termination of the Recipient’s Service shall be subject to Section 2.02(g). Each Option granted hereunder (other than a Nonemployee Directors Option) and all rights or obligations thereunder shall expire on such date as
shall be determined by the Administrator, but not later than ten years after the date the Option is granted and shall be subject to earlier termination as herein provided. 
 (d) Exercise of Options. Except as otherwise provided herein, an Option may become exercisable, in whole or in part, on the date or dates specified by the Administrator (or, in the case of
Nonemployee Directors’ Options, the Plan) at the time the Option is granted and thereafter shall remain exercisable until the expiration or earlier termination of the Option. No Option shall be exercisable except in respect of whole shares, and
fractional share interests shall be disregarded. An Option shall be deemed to be exercised when the Secretary of the Company receives written notice of such exercise from the Holder, together with payment of the Exercise Price made in accordance
with Section 2.02(e). Upon proper exercise, the Company shall deliver to the person entitled to exercise the Option or his or her designee a certificate or certificates for the shares of stock for which the Option is exercised. 

  
 8 








 (e) Form of Exercise Price. The aggregate Exercise Price shall be immediately
due and payable upon the exercise of an Option and shall, subject to the provisions of the Award Document, be payable in one or more of the following: (i) by delivery of legal tender of the United States, (ii) by delivery of shares of
Common Stock held for the requisite period, if any, necessary to avoid a charge to the Company’s earnings for financial reporting purposes, and/or (iii) through a sale and remittance procedure pursuant to which the Holder shall
concurrently provide irrevocable instructions to (A) a brokerage firm to effect the immediate sale of the purchased shares and remit to the Company, out of the sale proceeds available on the settlement date, sufficient funds to cover the
aggregate Exercise Price payable for the purchased shares plus all applicable income and employment taxes required to be withheld by the Company by reason of such exercise and (B) the Company to deliver the certificates for the purchased shares
directly to such brokerage firm in order to complete the sale. Any shares of Company stock or other non-cash consideration assigned and delivered to the Company in payment or partial payment of the Exercise Price will be valued at Fair Market Value
on the exercise date. 
 (f) Limitation on Exercise of Incentive Stock Options. The aggregate Fair Market Value
(determined as of the respective date or dates of grant) of the Common Stock for which one or more Options granted to any Recipient under the Plan (or any other option plan of the Company or any of its subsidiaries or affiliates) may for the first
time become exercisable as Incentive Stock Options under the Code during any one calendar year shall not exceed $100,000. Any Options granted as Incentive Stock Options pursuant to the Plan in excess of such limitation shall be treated as
Nonqualified Stock Options. Options are to be taken into account in the order in which they were awarded. 
 (g) Termination
of Service. 
 (i) Termination for Cause. Except as otherwise provided by the Administrator, in the event of a Just
Cause Dismissal of a Recipient, all of the outstanding Options granted to such Recipient shall expire and become unexercisable as of the date of such Just Cause Dismissal. 
 (ii) Termination Other Than for Cause. Subject to subsection (i) above and except as otherwise provided by the Administrator, in the event of a Recipient’s termination of Service from the
Company or its Related Corporations due to: 
 (A) any reason other than Just Cause Dismissal, death, or Permanent
Disability, or normal retirement, the outstanding Options granted to such Recipient, whether or not vested, shall expire and become unexercisable as of the earlier of (1) the date such Options would expire in accordance with their terms if the
Recipient had remained in Service or (2) three calendar months after the date the Recipient’s Service terminated in the case of Incentive Stock Options, or six months after the Recipient’s Service terminated, in the case of
Nonqualified Stock Options. 
 (B) death or Permanent Disability, the outstanding Options granted to such Recipient,
whether or not vested, shall expire and become unexercisable as of the earlier of (1) the date such Options would expire in accordance with their terms if the Recipient had remained in Service or twelve months after the date of termination.

 (C) normal retirement, the outstanding Options granted to such Recipient, whether or not vested, shall expire and become
unexercisable as of the earlier of (A) the date such Options expire in accordance with their terms or (B) twenty-four months after the date of retirement. 
 (iii) Termination of Director Service. In the event that a Director shall cease to be a Nonemployee Director, all outstanding Options granted to such Recipient shall be exercisable, to the extent
already vested and exercisable on the date such Recipient ceases to be a Nonemployee Director and regardless of the reason the Recipient ceases to be a Nonemployee Director until the fifth anniversary of the date such Director ceases to be a
Nonemployee Director; provided that the Administrator may extend such post-termination period to up to the expiration date of the Option. 

2.03 Performance Awards. 

(a) Grant of Performance Award. The Administrator may grant Performance Awards under the Plan and shall determine the
performance criteria (which need not be identical and may be established on an individual or group basis) governing Performance Awards, the terms thereof, and the form and timing of payment of Performance Awards. 

  
 9 








 (b) Payment of Award; Limitation. Upon satisfaction of the conditions applicable
to a Performance Award, payment will be made to the Holder in cash or in shares of Common Stock valued at Fair Market Value or a combination of Common Stock and cash, as the Administrator in its discretion may determine. Notwithstanding any other
provision of this Plan, no Eligible Person shall be paid Performance Awards with a value in excess of $1,000,000 in any one calendar year; provided, however, that this limitation shall not apply if it is not required in order for the compensation
attributable to the Performance Award hereunder to qualify as Performance-Based Compensation. 
 (c) Expiration of
Performance Award. If any Recipient’s Service is terminated for any reason other than normal retirement, death or Permanent Disability prior to the time a Performance Award or any portion thereof becomes payable, all of the Holder’s
rights under the unpaid portion of the Performance Award shall expire unless otherwise determined by the Administrator. In the event of termination of Service by reason of death, Permanent Disability or normal retirement, the Administrator, in its
discretion, may determine what portions, if any, of the Performance Award should be paid to the Holder. 
 2.04 Restricted Stock.

 (a) Award of Restricted Stock. The Administrator may issue Restricted Stock under the Plan. The Administrator
shall determine the Purchase Price (if any), the forms of payment of the Purchase Price (which shall be either cash or past services), the restrictions upon the Restricted Stock, and when such restrictions shall lapse (provided that the restriction
period shall be at least one year for performance-based grants and three years for non-performance-based grants). 

(b) Requirements of Restricted Stock. All shares of Restricted Stock granted or sold pursuant to the Plan will be subject to
the following conditions: 
 (i) No Transfer. The shares of Restricted Stock may not be sold, assigned, transferred,
pledged, hypothecated or otherwise disposed of, alienated or encumbered until the restrictions are removed or expire; 
 (ii)
Certificates. The Administrator may require that the certificates representing shares of Restricted Stock granted or sold to a Holder pursuant to the Plan remain in the physical custody of an escrow holder or the Company until all
restrictions are removed or expire; 
 (iii) Restrictive Legends. Each certificate representing shares of Restricted
Stock granted or sold to a Holder pursuant to the Plan will bear such legend or legends making reference to the restrictions imposed upon such Restricted Stock as the Administrator in its discretion deems necessary or appropriate to enforce such
restrictions; and 
 (iv) Other Restrictions. The Administrator may impose such other conditions on Restricted Stock as
the Administrator may deem advisable including, without limitation, restrictions under the Securities Act, under the Exchange Act, under the requirements of any stock exchange or upon which such Restricted Stock or shares of the same class are then
listed and under any blue sky or other securities laws applicable to such shares. 
 (c) Rights of Holder. Subject
to the provisions of Section 2.04(b) and any additional restrictions imposed by the Administrator, the Holder will have all rights of a stockholder with respect to the Restricted Stock, including the right to vote the shares and receive all
dividends and other distributions paid or made with respect thereto. 
 (d) Termination of Service. Unless the
Administrator in its discretion determines otherwise, upon a Recipient’s termination of Service for any reason, all of the Restricted Stock issued to the Recipient that remains subject to restrictions imposed pursuant to the Plan on the date of
such termination of Service may be repurchased by the Company at the Purchase Price (if any). 
 (e) Adjustments.
Any new, substituted or additional securities or other property which Holder may have the right to receive with respect to the Holder’s shares of Restricted Stock by reason of a merger, consolidation, reorganization, recapitalization,
reclassification, combination of shares, stock dividend, stock split, reverse stock split, exchange of shares or other change affecting the outstanding Common Stock without the Company’s receipt of consideration shall be issued subject to the
same vesting requirements applicable to the Holder’s shares of Restricted Stock and shall be treated as if they had been acquired on the same date as such shares.

 2.05 Stock Appreciation Rights. 

(a) Granting of Stock Appreciation Rights. The Administrator may grant Stock Appreciation Rights, either related or unrelated
to Options, under the Plan. 
 (b) Stock Appreciation Rights Related to Options. 

(i) A Stock Appreciation Right granted in connection with an Option granted under this Plan will entitle the holder of the related
Option, upon exercise of the Stock Appreciation Right, to surrender such Option, or any portion thereof to the extent unexercised, with respect to the number of shares as to which such Stock Appreciation Right is exercised, and to receive payment of
an amount computed pursuant to Section 2.05(b)(iii). Such Option will, to the extent surrendered, then cease to be exercisable. 
 (ii) A Stock Appreciation Right granted in connection with an Option hereunder will be exercisable at such time or times, and only to the extent that, the related Option is exercisable, and will not
be transferable except to the extent that such related Option may be transferable. 
 (iii) Upon the exercise of a Stock
Appreciation Right related to an Option, the Holder will be entitled to receive payment of an amount determined by multiplying: (i) the difference obtained by subtracting the Exercise Price of a share of Common Stock specified in the related
Option from the Fair Market Value of a share of Common Stock on the date of exercise of such Stock Appreciation Right (or as of such other date or as of the occurrence of such event as may have been specified in the instrument evidencing the grant
of the Stock Appreciation Right), by (ii) the number of shares as to which such Stock Appreciation Right is exercised. 

(c) Stock Appreciation Rights Unrelated to Options. The Administrator may grant Stock Appreciation Rights unrelated to
Options to Eligible Persons. Section 2.05(b)(iii) shall be used to determine the amount payable at exercise under such Stock Appreciation Right, except that in lieu of the Exercise Price specified in the related Option the initial base amount
specified in the Incentive Award shall be used. 
 (d) Limits. Notwithstanding the foregoing, the Administrator, in
its discretion, may place a dollar limitation on the maximum amount that will be payable upon the exercise of a Stock Appreciation Right under the Plan. 
 (e) Payments. Payment of the amount determined under the foregoing provisions may be made solely in whole shares of Common Stock valued at their Fair Market Value on the date of exercise of
the Stock Appreciation Right, in cash or in a combination of cash and shares of Common Stock as the Administrator deems advisable. If permitted by the Administrator, the Holder may elect to receive cash in full or partial settlement of a Stock
Appreciation Right. If the Administrator decides to make full payment in shares of Common Stock, and the amount payable results in a fractional share, payment for the fractional share will be made in cash. 

(f) Termination of Service. Section 2.02(g) will govern the treatment of Stock Appreciation Rights upon the termination
of a Recipient’s Service. 
 2.06 Stock Payments. 
 The Administrator may issue Stock Payments under the Plan for all or any portion of the compensation (other than base salary) or other payment that would otherwise become payable by the Company to the
Eligible Person in cash.

 2.07 Dividend Equivalents. 
 The Administrator may grant Dividend Equivalents to any Recipient who has received an Option, Stock Appreciation Right, or other Incentive Award denominated in shares of Common Stock. Such Dividend
Equivalents shall be effective and shall entitle the Recipients thereof to payments during the “Applicable Dividend Period,” which shall be (a) the period between the date the Dividend Equivalent is granted and the date the related
Option, Stock Appreciation Right, or other Incentive Award is exercised, terminates, or is converted to Common Stock, or (b) such other time as the Administrator may specify in the Award Document. Dividend Equivalents may be paid in cash,
Common Stock, or other Incentive Awards; the amount of Dividend Equivalents paid other than in cash shall be determined by the Administrator by application of such formula as the Administrator may deem appropriate to translate the cash value of
dividends paid to the alternative form of payment of the Dividend Equivalent. Dividend Equivalents shall be computed as of each dividend record date and shall be payable to Recipients thereof at such time as the Administrator may determine.
Notwithstanding the foregoing, if it is intended that an Incentive Award qualify as Performance-Based Compensation and the amount of the compensation the Eligible Person could receive under the award is based solely on an increase in value of the
underlying stock after the date of grant or award (i.e., the grant, vesting, or exercisability of the award is not conditioned upon the attainment of a preestablished, objective performance goal described in Section 1.01(x)), then the payment
of any Dividend Equivalents related to the Award shall not be made contingent on the exercise of the Award. 
 ARTICLE III

 NONEMPLOYEE DIRECTOR’S OPTIONS 
 3.01 Grants of Initial Awards. 
 Each Nonemployee Director shall, upon first
becoming a Nonemployee Director, receive a one-time grant of an Award on such terms as may be determined from time to time by the Administrator. Awards granted under this Section 3.01 vest in accordance with Section 3.04(a) hereof and are
“Initial Awards” for purposes hereof. 
 3.02 Grants of Additional Awards. 

On the date of the annual meeting of stockholders of the Company next following a Nonemployee Director becoming such, and on the date of
each subsequent annual meeting of stockholders of the Company, in each case if the Nonemployee Director has served as a director since his or her election or appointment and has been re-elected as a director at such annual meeting or is continuing
as a director without being re-elected due to the classification of the Board, such Nonemployee Director shall automatically receive an Award on such terms as may be determined from time to time by the Administrator Awards granted under this
Section 3.02 vest in accordance with Section 3.04(b) hereof and are “Additional Awards” for purposes hereof. Notwithstanding the foregoing to the contrary, the first grant of Additional Awards shall be made to eligible
Nonemployee Directors on the date of the 2010 annual meeting of stockholders. 
 3.03 Exercise Price. 

The Exercise Price for Nonemployee Directors’ Options shall be payable as set forth in Section 2.02(e). 

3.04 Vesting and Exercise. 
 (a) Initial Awards shall vest and become exercisable with respect to 25% of the underlying shares on the grant date and with respect to an additional 25% of the underlying shares on the dates of each
of the first three anniversaries of the date of grant provided the Recipient has remained a Nonemployee Director for the entire period from the date of grant to such date. 
 (b) Additional Awards shall vest and become exercisable upon the earlier of (i) the first anniversary of the grant date or (ii) immediately prior to the annual meeting of stockholders of
the Company next following the grant date, provided the Recipient has remained a Nonemployee Director for the entire period from the date of grant to such earlier date. 
 (c) Notwithstanding the foregoing, however, Initial Awards and Additional Awards that have not vested and become exercisable at the time the Recipient ceases to be a Nonemployee Director shall
expire. 

  
 12 









 3.05 Term of Options and Effect of Termination. 

No Nonemployee Directors’ Option shall be exercisable after the expiration of ten years from the date of its grant. In the event that
the Recipient of a Nonemployee Director’s Option shall cease to be a Nonemployee Director, all outstanding Nonemployee Directors’ Options granted to such Recipient shall be exercisable, to the extent already vested and exercisable on the
date such Recipient ceases to be a Nonemployee Director and regardless of the reason the Recipient ceases to be a Nonemployee Director until the fifth anniversary of the date such Director ceases to be a Nonemployee Director; provided that the
Administrator may extend such post-termination period to the expiration date of the Option. 
 ARTICLE IV 

RECAPITALIZATIONS AND REORGANIZATIONS 
 4.01 Corporate Transactions. 
 (a) Options. Unless the
Administrator provides otherwise in the Award Document or another written agreement, in the event of a Change in Control, the Administrator shall provide that all Options (other than Non-employee Director Options) either (i) vest in full
immediately preceding the Change in Control and terminate upon the Change in Control, (ii) are assumed or continued in effect in connection with the Change in Control transaction, (iii) are cashed out for an amount equal to the deal
consideration per share less the Exercise Price or (iv) are substituted for similar awards of the surviving corporation. Each Option that is assumed or otherwise continued in effect in connection with a Change in Control shall be appropriately
adjusted, immediately after such Change in Control, to apply to the number and class of securities which would have been issuable to Recipient in consummation of such Change in Control had the Recipient been exercised immediately prior to such
Change in Control. Appropriate adjustments to reflect such Change in Control shall also be made to (A) the Exercise Price payable per share under each outstanding Option, provided the aggregate Exercise Price payable for such securities shall
remain the same, (B) the maximum number and/or class of securities available for issuance over the remaining term of the Plan, (C) the maximum number and/or class of securities for which any one person may be granted options and direct
stock issuances pursuant to the Plan per calendar year and (D) the number and/or class of securities subject to Nonemployee Director’s Options. To the extent the holders of Common Stock receive cash consideration in whole or part for their
Common Stock in consummation of the Change in Control, the successor corporation may, in connection with the assumption of the outstanding Options, substitute one or more shares of its own common stock with a fair market value equivalent to the cash
consideration paid per share of Common Stock in such Change in Control transaction. 
 (b) Nonemployee Directors’
Options. Immediately prior to a Change of Control, all outstanding Nonemployee Directors’ Options shall vest in full. 

(c) Other Incentive Awards. The Administrator may specify the effect that a Change in Control has on an Incentive Award
(other than an Option) outstanding at the time such a Change in Control occurs either in the applicable Award Document or by subsequent modification of the Award. 
 4.02 No Restraint. 
 The grant of an Option pursuant to the Plan shall not
affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure or to merge or to consolidate or to dissolve, liquidate or sell, or transfer all of any part
of its business or assets.
