The Board shall have full power and authority to take all actions and to make all determinations required or provided for under the Plan, any Award or any Award Agreement, and shall have full power and authority to take all such other actions and make all such other determinations not inconsistent with the specific terms and provisions of the Plan that the Board deems to be necessary or appropriate to the administration of the Plan, any Award or any Award Agreement.  All such actions and determinations shall be by the affirmative vote of a majority of the members of the Board present at a meeting or by consent of the Board executed in writing in accordance with the Company’s certificate of incorporation and bylaws and applicable law.  The interpretation and construction by the Board of any provision of the Plan, any Award or any Award Agreement shall be final, binding and conclusive.  To the extent permitted by law, the Board may delegate its authority under the Plan to a member of the Board or an executive officer who is a member of the Board.

3.2                               Committee.

The Board from time to time may delegate to one or more Committees such powers and authorities related to the administration and implementation of the Plan, as set forth in Section 3.1 above and in other applicable provisions, as the Board shall determine, consistent with the certificate of incorporation and bylaws of the Company and applicable law.  In the event that the Plan, any Award or any Award Agreement entered into hereunder provides for any action to be taken by or determination to be made by the Board, such action may be taken by or such determination may be made by the applicable Committee if the power and authority to do so has been delegated to the Committee by the Board as provided for in this Section 3.2 and all references herein to the Board shall be deemed to be the Committee.  Unless otherwise expressly determined by the Board, any such action or determination by the Committee shall be final, binding and conclusive.  To the extent permitted by law, the Committee may delegate its authority under the Plan to a member of the Committee or an executive officer who is a member of the Committee.

Subject to the other terms and conditions of the Plan, the Board shall have full and final authority to:

(i)            designate Grantees;

(ii)           determine the type or types of Awards to be made to a Grantee;

(iii)          determine the number of shares of Stock to be subject to an Award;

(iv)          establish the terms and conditions of each Award (including, but not limited to, the Option Price of any Option, the nature and duration of any restriction or condition (or provision for lapse thereof) relating to the vesting, exercise, transfer, or forfeiture of an Award or the shares of Stock subject thereto, and any terms or conditions that may be necessary to qualify Options as Incentive Stock Options);

(v)           prescribe the form of each Award Agreement evidencing an Award; and

5

(vi)                              amend, modify, or supplement the terms of any outstanding Award (provided, that, no amendment, modification or supplement of any Award shall, without the consent of the Grantee, impair the Grantee’s rights under such Award).

The Board’s authority hereunder specifically includes the authority, in order to effectuate the purposes of the Plan but without amending the Plan, to modify Awards to eligible individuals who are foreign nationals or are individuals who are employed outside the United States to recognize differences in local law, tax policy, or custom.  Notwithstanding the foregoing, no amendment, modification or supplement of any Award shall, without the consent of the Grantee, impair the Grantee’s rights under such Award.

The Company may retain the right in an Award Agreement to cause a forfeiture of the gain realized by a Grantee on account of actions taken by the Grantee in violation or breach of or in conflict with any employment agreement, independent contractor agreement, consulting agreement, non-competition agreement, any agreement prohibiting solicitation of employees or clients of the Company or any Affiliate thereof or any confidentiality obligation with respect to the Company or any Affiliate thereof or otherwise in competition with the Company or any Affiliate thereof, to the extent specified in such Award Agreement applicable to the Grantee.  In addition, the Company may annul an Award if the Grantee is an employee of the Company or an Affiliate thereof and is terminated for Cause as defined in the applicable Award Agreement or the Plan, as applicable.

3.4                               Deferral Arrangement.

The Board may permit or require the deferral of any award payment into a deferred compensation arrangement, subject to such rules and procedures as it may establish, which may include provisions for the payment or crediting of interest or dividend equivalents, including converting such credits into deferred Stock equivalents.  Any such deferrals shall be made in a manner that complies with Code Section 409A.

3.5                               No Liability.

No member of the Board or of a Committee shall be liable for any action or determination made in good faith with respect to the Plan or any Award or Award Agreement.

3.6                               Share Issuance/Book Entry.

Notwithstanding any provision of this Plan to the contrary, the issuance of the Stock under the Plan may be evidenced in such a manner as the Board, in its discretion, deems appropriate, including, without limitation, book-entry registration or issuance of one or more Stock certificates.

4.                   STOCK SUBJECT TO THE PLAN

4.1                               Number of Shares Available for Awards.

Subject to adjustment as provided in Section 15 hereof, the number of shares of Stock available for issuance under the Plan shall equal 22,690,000.  All of the shares of Stock issuable

6

under the Plan may be issued as Incentive Stock Options.  Stock issued or to be issued under the Plan shall be authorized but unissued shares or, to the extent permitted by applicable law, issued shares that have been reacquired by the Company.

4.2                               Adjustments in Authorized Shares.

The Board shall have the right to substitute or assume Awards in connection with mergers, reorganizations, separations, or other transactions to which Section 424(a) of the Code applies. The number of shares of Stock reserved pursuant to Section 4.1 shall be increased by the corresponding number of Awards assumed and, in the case of a substitution, by the net increase in the number of shares of Stock subject to Awards before and after the substitution.

4.3                               Share Usage.

Shares covered by an Award shall be counted as of the Grant Date for purposes of calculating the number of shares available for issuance under Section 4.1.  If any shares covered by an Award are not purchased or are forfeited or expire, or if an Award otherwise terminates without delivery of any Stock subject thereto or is settled in cash in lieu of shares, then the number of shares of Stock counted against the aggregate number of shares available under the Plan with respect to such Award shall, to the extent of any such forfeiture, termination, or expiration again be available for making Awards under the Plan. If the exercise price of any Option or the tax withholding obligations of any Award granted under the Plan is satisfied by tendering shares of Stock to the Company (by either actual delivery or by attestation), only the number of shares of Stock issued net of the shares of Stock tendered shall be deemed delivered for purposes of determining the maximum number of shares of Stock available for delivery under the Plan.

5.                   EFFECTIVE DATE, DURATION AND AMENDMENTS

5.1                               Effective Date.

The Plan shall be effective as of the Effective Date, subject to approval of the Plan by the Company’s stockholders entitled to vote thereon within one year of the Effective Date.  Upon approval of the Plan by the stockholders of the Company entitled to vote thereon as set forth above, all Awards made under the Plan on or after the Effective Date shall be fully effective as if the stockholders of the Company entitled to vote thereon had approved the Plan on the Effective Date.  If the stockholders fail to approve the Plan within one year of the Effective Date, any Awards made hereunder shall be null and void and of no effect, and no additional Awards shall be made after such date.

5.2                               Term.

The Plan shall terminate automatically 10 years after the Effective Date and may be terminated on any earlier date as provided in Sections 5.3 or 15.3.  No Awards shall be made after termination of the Plan.

7

5.3                               Amendment and Termination of the Plan

The Board may, at any time and from time to time, amend, suspend, or terminate, in whole or in part, any or all of the provisions of this Plan and of any Award (including any amendment deemed necessary to ensure that the Company may comply with any regulatory requirement referred to herein), or suspend or terminate it entirely, retroactively or otherwise; provided, however, that if the Board, in its sole discretion, determines that the rights of a Grantee with respect to an Award granted prior to such amendment, suspension or termination, may be adversely impaired, the consent of such Grantee shall be required or the terms of such Grantee’s Award shall continue to be governed by the Plan without giving effect to any such amendment.  An amendment to the Plan shall be contingent on approval of the Company’s stockholders entitled to vote thereon only to the extent required by applicable law, regulations or rules.  For the avoidance of doubt, nothing in this Section 5.3 shall be deemed to limit the discretion of the Board under Section 15.3.

6.                   AWARD ELIGIBILITY

6.1                               Employees and Other Service Providers.

Awards (including Awards of Incentive Stock Options, subject to Section 6.2) may be made under the Plan to any employee, officer or director of, or other Service Provider providing services to, the Company or any Affiliate thereof.  To the extent required by applicable state law, Awards within certain states may be limited to employees and officers or employees, officers and directors.  An eligible person may receive more than one Award, subject to such restrictions as are provided herein.

6.2                               Limitations on Incentive Stock Options.

An Option shall constitute an Incentive Stock Option only (i) if the Grantee of such Option is an employee of the Company or any Subsidiary of the Company, (ii) to the extent specifically provided in the related Award Agreement and (iii) to the extent that the aggregate Fair Market Value (determined on the Grant Date) of the shares of Stock with respect to which all Incentive Stock Options held by such Grantee become exercisable for the first time during any calendar year (under the Plan and all other plans of the Grantee’s employer and its Affiliates) does not exceed $100,000.  This limitation shall be applied by taking Incentive Stock Options into account in the order in which they were granted.

7.                   AWARD AGREEMENT

Each Award pursuant to the Plan shall be evidenced by an Award Agreement, in such form or forms as the Board shall from time to time determine, which specifies the number of shares subject to the Award (subject to adjustment in accordance with Section 15).  Award Agreements granted from time to time or at the same time need not contain similar provisions but shall be consistent with the terms of the Plan.  Each Award Agreement evidencing an Award of Options shall specify whether such Options are intended to be Nonqualified Stock Options or Incentive Stock Options, and in the absence of such specification such options shall be deemed Nonqualified Stock Options.

8

8.                   TERMS AND CONDITIONS OF OPTIONS

8.1                               Option Price.

The Option Price of each Option shall be fixed by the Board and stated in the Award Agreement evidencing such Option.  The Option Price shall not be less than the Fair Market Value on the Grant Date of a share of Stock; provided, however, that in the event that a Grantee is a Ten-Percent Stockholder, the Option Price of an Incentive Stock Option granted to such Grantee shall be not less than 110% of the Fair Market Value of a share of Stock on the Grant Date.  In no case shall the Option Price of any Option be less than the par value of a share of Stock.

8.2                               Vesting.

Subject to Sections 8.3 and 15.3 hereof, each Option granted under the Plan shall become exercisable at such times and under such conditions as shall be determined by the Board and stated in the Award Agreement.  For purposes of this Section 8.2, fractional numbers of shares of Stock subject to an Option shall be rounded down to the next nearest whole number.  The Board may provide, for example, in the Award Agreement for (i) accelerated exercisability of the Option in the event the Grantee’s Service terminates on account of death, Disability or another event, (ii) expiration of the Option prior to its term in the event of the termination of the Grantee’s Service, (iii) immediate forfeiture of the Option in the event the Grantee’s Service is terminated for Cause or (iv) unvested Options to be exercised subject to the Company’s right of repurchase with respect to unvested shares of Stock.

8.3                               Term.

Each Option granted under the Plan shall terminate, and all rights to purchase shares of Stock thereunder shall cease, upon the expiration of 10 years from the Grant Date, or under such circumstances and on such date prior thereto as is set forth in the Plan or as may be fixed by the Board and stated in the Award Agreement relating to such Option; provided, however, that in the event that the Grantee is a Ten-Percent Stockholder, an Option granted to such Grantee that is intended to be an Incentive Stock Option shall not be exercisable after the expiration of five years from its Grant Date.

8.4                               Exercise of Options on Termination of Service.

Each Award Agreement shall set forth the extent to which the Grantee shall have the right to exercise the Option following termination of the Grantee’s Service.  Such provisions shall be determined in the sole discretion of the Board, need not be uniform among all Options issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of Service.

8.5                               Limitations on Exercise of Option.

Notwithstanding any other provision of the Plan, in no event may any Option be exercised, in whole or in part, prior to the date the Plan is approved by the stockholders of the Company entitled to vote thereon, or after 10 years following the Grant Date, or after the

9

occurrence of an event referred to in Section 15 hereof which results in termination of the Option.

8.6                               Exercise Procedure.

An Option that is exercisable may be exercised by the Grantee’s delivery to the Company of written notice of exercise on any business day, at the Company’s principal office, in the form specified by the Company.  Such notice shall specify the number of shares of Stock with respect to which the Option is being exercised and shall be accompanied by payment in full of the Option Price of the shares for which the Option is being exercised.  The minimum number of shares of Stock with respect to which an Option may be exercised, in whole or in part, at any time shall be the lesser of (i) 100 shares or such lesser number set forth in the applicable Award Agreement and (ii) the maximum number of shares available for purchase under the Option at the time of exercise.  The Option Price shall be payable in a form described in Section 10.

8.7                               Right of Holders of Options.

Unless otherwise stated in the applicable Award Agreement, an individual holding or exercising an Option shall have none of the rights of a stockholder of the Company (for example, the right to cash or dividend payments or distributions attributable to the subject shares of Stock) until the shares of Stock covered thereby are fully paid and issued to such individual.

8.8                               Delivery of Stock Certificates.

Promptly after the exercise of an Option by a Grantee and the payment in full of the Option Price, such Grantee shall be entitled to the issuance of a stock certificate or certificates evidencing such Grantee’s ownership of the shares of Stock purchased upon such exercise of the Option.  Notwithstanding any other provision of this Plan to the contrary, the Company may elect to satisfy any requirement under this Plan for the delivery of stock certificates through the use of book-entry.

8.9                               Transferability of Options.

Except as provided in Section 8.10, during the lifetime of a Grantee, only the Grantee (or, in the event of legal incapacity or incompetency, the Grantee’s guardian or legal representative) may exercise an Option.  Except as provided in Section 8.10, no Option shall be assignable or transferable by the Grantee to whom it is granted, other than by will or the laws of descent and distribution.

8.10                        Family Transfers.

If authorized in the applicable Award Agreement, a Grantee may transfer, not for value, all or part of an Option that is not an Incentive Stock Option to any Family Member.  For the purpose of this Section 8.10, a “not for value” transfer is a transfer which is (i) a gift, (ii) a transfer under a domestic relations order in settlement of marital property rights, or (iii) unless applicable law does not permit such transfers, a transfer to an entity in which more than 50% of the voting interests are owned by Family Members (or the Grantee) in exchange for an interest in that entity.  Following a transfer under this Section 8.10, any such Option shall continue to be

10

subject to the same terms and conditions as were applicable immediately prior to transfer, and shares of Stock acquired pursuant to the Option shall be subject to the same restrictions on transfer of shares as would have applied to the Grantee.  Subsequent transfers of transferred Options are prohibited except to Family Members of the original Grantee in accordance with this Section 8.10 or by will or the laws of descent and distribution.  The events of termination of Service under an Option shall continue to be applied with respect to the original Grantee, following which the Option shall be exercisable by the transferee only to the extent, and for the periods specified in the applicable Award Agreement, and the shares may be subject to repurchase by the Company or its assignee.

8.11                        Notice of Disqualifying Disposition.

If any Grantee shall make any disposition of shares of Stock issued pursuant to the exercise of an Incentive Stock Option under the circumstances described in Code Section 421(b) (relating to certain disqualifying dispositions), such Grantee shall notify the Company of such disposition within 10 days thereof.

9.                   TERMS AND CONDITIONS OF RESTRICTED STOCK AND STOCK UNITS

9.1                               Award of Restricted Stock and Stock Units.

The Board may from time to time grant Restricted Stock or Stock Units to persons eligible to receive Awards under Section 6 hereof, subject to such restrictions, conditions and other terms as the Board may determine.

9.2                               Restrictions.

At the time an Award of Restricted Stock or Stock Units is made, the Board, in its sole discretion, shall establish a restriction period applicable to such Restricted Stock or Stock Units.  Each Award of Restricted Stock or Stock Units may be subject to a different restriction period.  The Board may, in its sole discretion, at the time an Award of Restricted Stock or Stock Units is made, prescribe conditions that must be satisfied prior to the expiration of the restriction period, including the satisfaction of corporate or individual performance objectives or continued Service, in order that all or any portion of the Restricted Stock or Stock Units shall vest.

The Board also may, in its sole discretion, shorten or terminate the restriction period or waive any of the conditions applicable to all or a portion of the Restricted Stock or Stock Units.  The Restricted Stock or Stock Units may not be sold, transferred, assigned, pledged or otherwise encumbered or disposed of during the restriction period or prior to the satisfaction of any other conditions prescribed by the Board with respect to such Restricted Stock or Stock Units.

9.3                               Restricted Stock Certificates.

The Company shall issue, in the name of each Grantee to whom Restricted Stock has been granted, stock certificates representing the total number of shares of Restricted Stock granted to such Grantee, as soon as reasonably practicable after the applicable Grant Date.  The Board may provide in an Award Agreement that either (i) the Secretary of the Company shall hold such certificates for the Grantee’s benefit until such time as the Restricted Stock is forfeited

11

to the Company, or the restrictions lapse, or (ii) such certificates shall be delivered to the Grantee; provided, however, that such certificates shall bear a legend or legends that complies with the applicable securities laws and regulations and makes appropriate reference to the restrictions imposed under the Plan and the Award Agreement.

9.4                               Rights of Holders of Restricted Stock.

Holders of Restricted Stock shall have the right to vote such Stock and, unless the Board otherwise provides in an Award Agreement, to receive any dividends declared or paid with respect to such Stock.  The Board may provide that any dividends paid on Restricted Stock must be reinvested in shares of Stock, which may or may not be subject to the same or other vesting conditions and restrictions applicable to such Restricted Stock.  All distributions, if any, received by a Grantee with respect to Restricted Stock as a result of any stock split, stock dividend, combination of shares, or other similar transaction shall be subject to the restrictions applicable to the original Award.

9.5                               Rights of Holders of Stock Units.

9.5.1                                 Voting and Dividend Rights.

9.5.2                                 Creditor’s Rights.

A holder of Stock Units shall have no rights other than those of a general creditor of the Company.  Stock Units represent an unfunded and unsecured obligation of the Company, subject to the terms and conditions of the applicable Award Agreement.

9.6                               Termination of Service.

Unless otherwise provided by the Board in the applicable Award Agreement, upon the termination of a Grantee’s Service with the Company or an Affiliate thereof, any shares of Restricted Stock or Stock Units held by such Grantee that have not vested, or with respect to which all applicable restrictions and conditions have not lapsed, shall immediately be deemed forfeited.  Upon forfeiture of Restricted Stock or Stock Units, the Grantee shall have no further rights with respect to such Award, including, but not limited to, the right to vote Restricted Stock and any right to receive dividends with respect to shares of Restricted Stock or Stock Units.

9.7                               Purchase and Delivery of Stock.

To the extent required by applicable law, the Grantee shall be required to purchase the Restricted Stock or Stock Units from the Company at a Purchase Price equal to the greater of (i)

12

the aggregate par value of the shares of Stock represented by such Restricted Stock or Stock Units or (ii) the Purchase Price, if any, specified in the Award Agreement relating to such Restricted Stock or Stock Units.  The Purchase Price shall be payable in a form described in Section 10 or, in the discretion of the Board, in consideration for past or future Services rendered to the Company or an Affiliate thereof.

Upon the expiration or termination of the restriction period and the satisfaction of any other conditions prescribed by the Board, having properly paid the Purchase Price, the restrictions applicable to shares of Restricted Stock or Stock Units settled in Stock shall lapse, and, unless otherwise provided in the Award Agreement, a stock certificate for such shares shall be delivered, free of all such restrictions, to the Grantee or the Grantee’s beneficiary or estate, as the case may be, upon the surrender of any stock certificate(s) previously issued to such Grantee in respect of such shares.  Neither the Grantee, nor the Grantee’s beneficiary or estate, shall have any further rights with regard to a Stock Unit once the share of Stock represented by the Stock Unit has been delivered.

10.            FORM OF PAYMENT

Payment of the Option Price for the shares purchased pursuant to the exercise of an Option or the Purchase Price for Restricted Stock or Stock Units shall be made in cash or in cash equivalents acceptable to the Company.  In addition, to the extent the Award Agreement so provides, payment of the Option Price for shares purchased pursuant to exercise of an Option or the Purchase Price for Restricted Stock or Stock Units may be made in any other form that is consistent with applicable laws, regulations and rules, including, without limitation, by cashless exercise procedure or by tender or attestation to the Company of shares of Stock, which shall be valued, for purposes of determining the extent to which such Option Price or Purchase Price has been paid thereby, at their Fair Market Value on the date of such tender or attestation.

11.            WITHHOLDING TAXES

The Company or an Affiliate thereof, as the case may be, shall have the right to deduct from payments of any kind otherwise due to a Grantee any federal, state, or local taxes of any kind required by applicable law to be withheld with respect to the vesting of or other lapse of restrictions applicable to an Award or upon the issuance of any shares of Stock or payment of any kind upon the exercise of an Option or pursuant to any other Award.  At the time of such vesting, lapse, or exercise, the Grantee shall pay to the Company or the Affiliate thereof, as the case may be, any amount that the Company or the Affiliate thereof may reasonably determine to be necessary to satisfy such withholding obligation; provided that if there is a same-day sale of shares of Stock subject to an Award, the Grantee shall pay such withholding obligation on the day on which such same-day sale is completed.  Subject to the prior approval of the Company or the Affiliate thereof, which may be withheld by the Company or the Affiliate thereof, as the case may be, in its sole discretion, the Grantee may elect to satisfy such obligations, in whole or in part, (i) by causing the Company or the Affiliate thereof to withhold shares of Stock otherwise issuable to the Grantee or (ii) by delivering to the Company or the Affiliate shares of Stock already owned by the Grantee.  The shares of Stock so delivered or withheld shall have an aggregate Fair Market Value equal to such withholding obligations.  The Fair Market Value of the shares of Stock used to satisfy such withholding obligation shall be determined by the Board

13

as of the date that the amount of tax to be withheld is to be determined.  A Grantee who has made an election pursuant to this Section 11 may satisfy his or her withholding obligation only with shares of Stock that are not subject to any repurchase, forfeiture, unfulfilled vesting, or other similar requirements.

The maximum number of shares of Stock that may be withheld from any Award to satisfy any federal, state, or local tax withholding requirements upon the exercise, vesting, or lapse of restrictions applicable to any Award or payment of shares of Stock pursuant to such Award, as applicable, may not exceed such number of shares of Stock having a Fair Market Value equal to the minimum statutory amount required by the Company or the applicable Affiliate to be withheld and paid to any such federal, state, or local taxing authority with respect to such exercise, vesting, lapse of restrictions, or payment of shares of Stock; provided, however, if the Company has adopted Accounting Standards Update 2016-09 (“AS 2016-09”) or AS 2016-09 or a similar rule is otherwise in effect, the Board has full discretion to choose, or to allow a Grantee to elect, to withhold a number of shares of Stock having an aggregate Fair Market Value that is greater than the applicable minimum required statutory withholding obligation (but such withholding may in no event be in excess of the maximum statutory withholding amount(s) in a Grantee’s relevant tax jurisdictions).

12.            RESTRICTIONS ON TRANSFER OF SHARES OF STOCK

12.1                        Right of First Refusal.

Any shares of Stock acquired by, or delivered or issued to, the Grantee under the Plan may be subject to a right of first refusal in favor of the Company, as the Board may determine, consistent with applicable law.  Any such right shall be set forth in an Award Agreement or in a stockholders or other similar agreement.

12.2                        Repurchase and Other Rights.

Stock issued upon exercise of an Option or pursuant to an Award of Restricted Stock or Stock Units may be subject to such right of repurchase upon termination of Service or other transfer restrictions as the Board may determine, consistent with applicable law.  Any additional restrictions shall be set forth in an Award Agreement or in a stockholders or other similar agreement.

12.3                        Legend.

In order to enforce the restrictions imposed upon shares of Stock under this Plan or as provided in an Award Agreement, the Board may cause a legend or legends to be placed on any certificate representing shares issued pursuant to this Plan that complies with the applicable securities laws and regulations and makes appropriate reference to the restrictions imposed under it.

13.            PARACHUTE LIMITATIONS

Notwithstanding any other provision of this Plan or of any other agreement, contract or understanding heretofore or hereafter entered into by a Grantee with the Company or any

14

Affiliate thereof, except an agreement, contract or understanding that expressly addresses Section 280G or Section 4999 of the Code (an “Other Agreement”), and notwithstanding any formal or informal plan or other arrangement for the direct or indirect provision of compensation to the Grantee (including groups or classes of participants or beneficiaries of which the Grantee is a member), whether or not such compensation is deferred, is in cash, or is in the form of a benefit to or for the Grantee (a “Benefit Arrangement”), if the Grantee is a “disqualified individual,” as defined in Section 280G(c) of the Code, any Awards held by that Grantee and any right to receive any payment or other benefit under this Plan shall not become exercisable or vested (i) to the extent that such right to exercise, vesting, payment, or benefit, taking into account all other rights, payments, or benefits to or for the Grantee under this Plan, all Other Agreements, and all Benefit Arrangements, would cause any payment or benefit to the Grantee under this Plan to be considered a “parachute payment” within the meaning of Section 280G(b)(2) of the Code as then in effect (a “Parachute Payment”) and (ii) if, as a result of receiving a Parachute Payment, the aggregate after-tax amounts received by the Grantee from the Company under this Plan, all Other Agreements, and all Benefit Arrangements would be less than the maximum after-tax amount that could be received by the Grantee without causing any such payment or benefit to be considered a Parachute Payment.  In the event that the receipt of any such right to exercise, vesting, payment, or benefit under this Plan, in conjunction with all other rights, payments, or benefits to or for the Grantee under any Other Agreement or any Benefit Arrangement would cause the Grantee to be considered to have received a Parachute Payment under this Plan that would have the effect of decreasing the after-tax amount received by the Grantee as described in clause (ii) of the preceding sentence, then those rights, payments, or benefits under this Plan, any Other Agreements, and any Benefit Arrangements shall be reduced or eliminated so as to avoid having the payment or benefit to the Grantee be deemed to be a Parachute Payment.  The Company shall reduce or eliminate the Parachute Payments by first reducing or eliminating any cash payments benefits (with the payments to be made furthest in the future being reduced first), then by reducing or eliminating any accelerated vesting of Options, then by reducing or eliminating any accelerated vesting of Restricted Stock or Stock Units, then by reducing or eliminating any other remaining Parachute Payments.  For the avoidance of doubt, no reduction or elimination of Parachute Payments shall be made without giving effect to the results of any applicable shareholder vote under Section 280G of the Code.

14.            REQUIREMENTS OF LAW

14.1                        General.

The Company shall not be required to sell or issue any shares of Stock under any Award if the sale or issuance of such shares would constitute a violation by the Grantee, any other individual exercising a right emanating from such Award, or the Company of any provision of any law or regulation of any governmental authority, including without limitation any federal or state securities laws or regulations.  If at any time the Company shall determine, in its discretion, that the listing, registration or qualification of any shares subject to an Award upon any securities exchange or under any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance or purchase of shares hereunder, no shares of Stock may be issued or sold to the Grantee or any other individual exercising an Option pursuant to such Award unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Company, and any delay caused

15

thereby shall in no way affect the date of termination of the Award.  Without limiting the generality of the foregoing, in connection with the Securities Act, upon the exercise of any right emanating from such Award or the delivery of any shares of Restricted Stock, unless a registration statement under the Securities Act is in effect with respect to the shares of Stock covered by such Award, the Company shall not be required to sell or issue such shares unless the Board has received evidence satisfactory to it that the Grantee or any other individual exercising an Option may acquire such shares pursuant to an exemption from registration under the Securities Act.  Any determination in this connection by the Board shall be final, binding, and conclusive.  The Company may, but shall in no event be obligated to, register any securities covered hereby pursuant to the Securities Act.  The Company shall not be obligated to take any affirmative action in order to cause the exercise of an Option or the issuance of shares of Stock pursuant to the Plan to comply with any law or regulation of any governmental authority.  As to any jurisdiction that expressly imposes the requirement that an Option shall not be exercisable until the shares of Stock covered by such Option are registered or are exempt from registration, the exercise of such Option (under circumstances in which the laws of such jurisdiction apply) shall be deemed conditioned upon the effectiveness of such registration or the availability of such an exemption.

14.2                        Rule 16b-3.

During any time when the Company has a class of equity security registered under Section 12 of the Exchange Act, it is the intent of the Company that Awards pursuant to the Plan and the exercise of Options granted hereunder will qualify for the exemption provided by Rule 16b-3 under the Exchange Act.  To the extent that any provision of the Plan or action by the Board does not comply with the requirements of Rule 16b-3, it shall be deemed inoperative to the extent permitted by law and deemed advisable by the Board, and shall not affect the validity of the Plan.  In the event that Rule 16b-3 is revised or replaced, the Board may exercise its discretion to modify this Plan in any respect necessary to satisfy the requirements of, or to take advantage of any features of, the revised exemption or its replacement.

15.            EFFECT OF CHANGES IN CAPITALIZATION

15.1                        Changes in Stock.

If the number of outstanding shares of Stock is increased or decreased or the shares of Stock are changed into or exchanged for a different number or kind of shares or other securities of the Company on account of any recapitalization, reclassification, stock split, reverse split, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock, or other increase or decrease in such shares effected without receipt of consideration by the Company occurring after the Effective Date, the number and kinds of shares for which Awards may be made under the Plan shall be adjusted proportionately and accordingly by the Board.  In addition, the number and kind of shares for which Awards are outstanding shall be adjusted proportionately and accordingly so that the proportionate interest of the Grantee immediately following such event shall, to the extent practicable, be the same as immediately before such event.  Any such adjustment in outstanding Options shall not change the aggregate Option Price payable with respect to shares that are subject to the unexercised portion of an outstanding Option, but shall include a corresponding proportionate adjustment in the Option Price per share.  The conversion of

16

any convertible securities of the Company that have been issued for consideration and which are converted in accordance with their terms, shall not be treated as an increase in shares effected without receipt of consideration.   Notwithstanding the foregoing, in the event of any distribution to the Company’s stockholders of securities of any other entity or other assets (including an extraordinary dividend but excluding a non-extraordinary dividend of the Company) without receipt of consideration by the Company, the Company shall, in such manner as the Company deems appropriate, adjust (i) the number and kind of shares subject to outstanding Awards and/or (ii) the exercise price of outstanding Options to reflect such distribution.

15.2                        Reorganization in Which the Company Is the Surviving Entity and in Which No Corporate Transaction Occurs.

Subject to the exception set forth in the last sentence of Section 15.4, if the Company shall be the surviving entity in any reorganization, merger, or consolidation of the Company with one or more other entities and in which no Corporate Transaction occurs, any Award theretofore made pursuant to the Plan shall pertain to and apply to the securities to which a holder of the number of shares of Stock subject to such Award would have been entitled immediately following such reorganization, merger, or consolidation, and with a corresponding proportionate adjustment of the Option Price per share so that the aggregate Option Price thereafter shall be the same as the aggregate Option Price of the shares remaining subject to the Option immediately prior to such reorganization, merger, or consolidation.  In the event of a transaction described in this Section 15.2, Stock Units shall be adjusted so as to apply to the securities that a holder of the number of shares of Stock subject to the Stock Units would have been entitled to receive immediately following such transaction.

15.3                        Corporate Transaction.

Subject to the last sentence of Section 15.4, the Board shall have the discretion to determine the effect of a Corporate Transaction on any outstanding Awards.  Without limiting the generality of the foregoing, in connection with a Corporate Transaction the Board may elect, in its sole discretion, to (a) cancel any outstanding Awards and pay or deliver, or cause to be paid or delivered, to the holder thereof an amount in cash or securities having a value (as determined by the Board acting in good faith) equal to the product of the number of shares of Stock subject to the Award (the “Grant Shares”) multiplied by, (i) in the case of Options, the amount, if any, by which (I) the formula or fixed price per share paid to holders of shares of Stock pursuant to such transaction exceeds (II) the Option Price applicable to such Grant Shares, and (ii) in the case of Restricted Stock and Stock Units, the formula or fixed price per share paid to holders of shares of Stock pursuant to the transaction, (b) provide in connection with such Corporate Transaction for the assumption or continuation of the Options theretofore granted, or for the substitution for such Awards for new common stock options relating to the stock of a successor entity, or a parent or subsidiary thereof, with appropriate adjustments as to the number of shares (disregarding any consideration that is not common stock) and option prices, such that Awards theretofore granted shall continue in the manner and under the terms so provided, (c) cancel any outstanding Awards that are unvested (or any unvested portion thereof) without payment to the holders thereof, or (d) cancel any outstanding Awards to the extent the Option Price applicable to the Grant Shares issuable thereunder is greater than the formula or fixed price per share paid to

17

holders of shares of Stock pursuant to such transaction, with or without any payment to the holders thereof.

If the Company establishes an exercise window in connection with a scheduled consummation of a Corporate Transaction, any exercise of an Option during such period shall be conditioned upon the consummation of the event and shall be effective only immediately before the consummation of the event.  Upon the consummation of any Corporate Transaction, the Plan and all outstanding but unexercised Options shall terminate.  The Board shall send written notice of an event that will result in such a termination to all individuals who hold Options not later than the time at which the Company gives notice thereof to its holders of Stock.

Notwithstanding the foregoing or any other provisions contained herein, the Board, in its sole discretion, may provide for the accelerated vesting or lapse of restrictions of Awards at any time.

15.4                        Adjustments.

Adjustments under Section 15 related to shares of Stock or securities of the Company shall be made by the Board, whose determination in that respect shall be final, binding and conclusive.  No fractional shares or other securities shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole share.  The Board may provide in Award Agreements at the time of grant, or any time thereafter with the consent of the Grantee, for different provisions to apply to an Award in place of those described in Sections 15.1, 15.2 and 15.3.

15.5                        No Limitations on Company.

The making of Awards pursuant to the Plan shall not affect or limit 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, consolidate, dissolve, or liquidate, or to sell or transfer all or any part of its business or assets.

16.            GENERAL PROVISIONS

16.1                        Stockholders Agreement

As a condition precedent to an Award, the exercise of an Option, or to the delivery of shares of Stock issued pursuant to any Option, the Grantee or his Family Member, as the case may be, shall become a party to the Company’s stockholders agreement, as it may be amended from time to time or any other agreement regarding the Stock, in such forms as the Board may determine from time to time (collectively, “Stockholders Agreements”).  Any shares of Stock acquired pursuant to the Plan shall be subject in all cases to the provisions of the Stockholders Agreements.  In the event of any inconsistency between the Plan, an Award Agreement and the Stockholders Agreements, the provisions of the Stockholders Agreements shall control.

18

16.2                        Disclaimer of Rights.

No provision in the Plan or in any Award or Award Agreement shall be construed to confer upon any individual the right to remain in the employ or service of the Company or any Affiliate thereof, or to interfere in any way with any contractual or other right or authority of the Company either to increase or decrease the compensation or other payments to any individual at any time, or to terminate any employment or other relationship between any individual and the Company or any Affiliate thereof.  The obligation of the Company to pay any benefits pursuant to this Plan shall be interpreted as a contractual obligation to pay only those amounts described herein, in the manner and under the conditions prescribed herein.  The Plan shall in no way be interpreted to require the Company to transfer any amounts to a third party trustee or otherwise hold any amounts in trust or escrow for payment to any participant or beneficiary under the terms of the Plan.

16.3                        Nonexclusivity of the Plan.

Neither the adoption of the Plan nor the submission of the Plan to the stockholders of the Company entitled to vote thereon for approval shall be construed as creating any limitations upon the right and authority of the Board to adopt such other incentive compensation arrangements (which arrangements may be applicable either generally to a class or classes of individuals or specifically to a particular individual or particular individuals) as the Board in its discretion determines desirable, including, without limitation, the granting of stock options otherwise than under the Plan.

16.4                        Captions.

The use of captions in this Plan or any Award Agreement is for the convenience of reference only and shall not affect the meaning of any provision hereof or thereof.

16.5                        Other Award Agreement Provisions.

Each Award under the Plan may contain such other terms and conditions not inconsistent with the Plan as may be determined by the Board, in its sole discretion.

16.6                        Number and Gender.

With respect to words used in this Plan, the singular form shall include the plural form, the masculine gender shall include the feminine gender, etc., as the context requires.

16.7                        Severability.

If any provision of the Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and all provisions shall remain enforceable in any other jurisdiction.

19

16.8                        Governing Law.

The validity and construction of this Plan and the instruments evidencing the Awards awarded hereunder shall be governed by the laws of the State of Delaware other than any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan and the instruments evidencing the Awards awarded hereunder to the substantive laws of any other jurisdiction.

16.9                        Code Section 409A.

The Board intends to comply with Section 409A of the Code, or an exemption to Section 409A of the Code, with regard to Awards hereunder that constitute nonqualified deferred compensation within the meaning of Section 409A of the Code.  To the extent that the Board determines that a Grantee would be subject to the additional 20% tax imposed on certain nonqualified deferred compensation plans pursuant to Section 409A of the Code as a result of any provision of any Award granted under this Plan, such provision shall be deemed amended to the minimum extent necessary to avoid application of such additional tax.  The nature of any such amendment shall be determined by the Board.
