in the case of a Committee, the specific duties delegated by the Board to such Committee, and subject to the approval of any relevant authorities, the Administrator shall have the authority in its discretion: 
 (i) to determine the Fair Market Value;

 (iii) to determine the number of Shares to be covered by each such Option granted hereunder;

 (viii) to construe and interpret
the terms of the Plan and Options granted pursuant to the Plan. 
  

 3. 

 (c) Effect of Administrator’s Decision. All decisions,
determinations and interpretations of the Administrator shall be final and binding on all Optionees. 
 5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 
 6. Limitations. 
 (a) Incentive Stock Option Limit. Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the
aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as
of the time the Option with respect to such Shares is granted. 
 (b) At-Will Employment. Neither the Plan
nor any Option or Stock Purchase Right shall confer upon any Optionee any right with respect to continuing the Optionee’s relationship as a Service Provider with the Company, nor shall it interfere in any way with his or her right or the
Company’s right to terminate such relationship at any time, with or without cause, and with or without notice. 
 7. Term of
Plan. Subject to shareholder approval in accordance with Section 19, the Plan shall become effective upon its adoption by the Board. Unless sooner terminated under Section 15, it shall continue in effect for a term of ten
(10) years from the later of (i) the effective date of the Plan, or (ii) the earlier of the most recent board or shareholder approval of an increase in the number of Shares reserved for issuance under the Plan. 
 8. Term of Option. The term of each Option shall be stated in the Option Agreement; provided, however, that the term shall be no more
than ten (10) years from the date of grant thereof. In the case of an Incentive Stock Option granted to an Optionee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant or such shorter term as may be provided in the Option Agreement. 
 9. Option Exercise Price and Consideration. 
 (a) Exercise Price. The per share exercise price for the Shares to be issued upon exercise of an Option shall be such price as is determined by the Administrator, but shall be subject to the
following: 
 (i) In the case of an Incentive Stock Option 
 (A) granted to an Employee who, at the time of grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary, the exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. 
 (B) granted to any other Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the
date of grant. 
 (ii) In the case of a Nonstatutory Stock Option, the per Share exercise price shall be determined by
the Administrator. 
 (iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other
than as required above pursuant to a merger or other corporate transaction. 
  

 4. 

 (b) Forms of Consideration. The consideration to be paid for the Shares
to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant). Such consideration may consist of, without
limitation, (1) cash, (2) check, (3) promissory note, (4) other Shares, provided Shares acquired directly from the Company (x) have been owned by the Optionee for more than six months on the date of surrender, and
(y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which such Option shall be exercised, (5) consideration received by the Company under a cashless exercise program implemented
by the Company in connection with the Plan, or (6) any combination of the foregoing methods of payment. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration
may be reasonably expected to benefit the Company. 
 10. Exercise of Option. 
 (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable according to the
terms hereof at such times and under such conditions as determined by the Administrator and set forth in the Option Agreement. Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be suspended during any unpaid
leave of absence. An Option may not be exercised for a fraction of a Share. 
 An Option shall be deemed exercised when the
Company receives: (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised.
Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse. Until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or
receive dividends or any other rights as a shareholder shall exist with respect to the Shares, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No
adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 13 of the Plan. 
 Exercise of an Option in any manner shall result in a decrease in the number of Shares thereafter available, both for purposes of the Plan
and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 (b) Termination of
Relationship as a Service Provider. If an Optionee ceases to be a Service Provider, such Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement to the extent that the Option is vested on
the date of termination (but in no event later than the expiration of the term of the Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three
(3) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time specified by the Administrator, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 
 (c) Disability of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee’s Disability,
the Optionee may exercise his or her Option within such period of time as is specified in the Option Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set
forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s termination. If, on the date of termination, the Optionee is
not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option 

  

 5. 

 
shall revert to the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan. 
 (d) Death of Optionee. If an
Optionee dies while a Service Provider, the Option may be exercised within such period of time as is specified in the Option Agreement (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement), by
the Optionee’s designated beneficiary, provided such beneficiary has been designated prior to Optionee’s death in a form acceptable to the Administrator. If no such beneficiary has been designated by the Optionee, then such Option may be
exercised by the personal representative of the Optionee’s estate or by the person(s) to whom the Option is transferred pursuant to the Optionee’s will or in accordance with the laws of descent and distribution. In the absence of a
specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the Optionee’s termination. If, at the time of death, the Optionee is not vested as to his or her entire Option, the Shares
covered by the unvested portion of the Option shall immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

 (e) Leaves of Absence. 
 (i) Unless the Administrator provides otherwise, vesting of Options granted hereunder shall be suspended during any unpaid leave of
absence. 
 (ii) A Service Provider shall not cease to be an Employee in the case of (A) any leave of absence
approved by the Company or (B) transfers between locations of the Company or between the Company, its Parent, any Subsidiary, or any successor. 
 (iii) For purposes of Incentive Stock Options, no such leave may exceed ninety (90) days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon
expiration of a leave of absence approved by the Company is not so guaranteed, then three (3) months following the ninety-first (91st) day of such leave, any Incentive Stock Option held by the Optionee shall cease to be treated as an Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory Stock Option. 
 11. Stock Purchase Rights. 
 (a) Rights to Purchase. Stock Purchase Rights may be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the
Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing or electronically of the terms, conditions and restrictions related to the offer, including the number of Shares that such
person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such offer. The offer shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator.

 (b) Repurchase Option. Unless the Administrator determines otherwise, the Restricted Stock Purchase
Agreement shall grant the Company a repurchase option exercisable within ninety (90) days of the voluntary or involuntary termination of the purchaser’s service with the Company for any reason (including death or disability). The purchase
price for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse
at such rate as the Administrator may determine. 
 (c) Other Provisions. The Restricted Stock Purchase
Agreement shall contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 (d) Rights as a Shareholder. Once the Stock Purchase Right is exercised, the purchaser shall have rights equivalent to
those of a shareholder and shall be a shareholder when his or her purchase is 

  

 6. 

 
entered upon the records of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or other right for which the record
date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 13 of the Plan. 
 12. Transferability of Options or Stock Purchase Rights. Unless determined otherwise by the Administrator, Options or Stock Purchase Rights may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in
any manner other than by will or the laws of descent and distribution, and may be exercised during the lifetime of the Optionee, only by the Optionee. 
 13. Adjustments; Dissolution or Liquidation; Merger or Change in Control. 
 (a) Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, in order to prevent
diminution or enlargement of the benefits or potential benefits intended to be made available under the Plan, shall adjust the number and class of Shares that may be delivered under the Plan and/or the number, class, and price of Shares covered by
each outstanding Option or Stock Purchase Right 
 (b) Dissolution or Liquidation. In the event of the
proposed dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Option or Stock
Purchase Right will terminate immediately prior to the consummation of such proposed action. 
 (c) Merger or Change
in Control. In the event of a merger of the Company with or into another corporation, or a Change in Control, each outstanding Option and Stock Purchase Right shall be assumed or an equivalent option substituted by the successor corporation
or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation in a merger or Change in Control refuses to assume or substitute for the Option or Stock Purchase Right, then the Optionee shall fully vest in and
have the right to exercise the Option or Stock Purchase Right as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable. If an Option or Stock Purchase Right becomes fully vested and exercisable in
lieu of assumption or substitution in the event of a merger or Change in Control, the Administrator shall notify the Optionee in writing or electronically that this Option or Stock Purchase Right shall be fully exercisable for a period of fifteen
(15) days from the date of such notice, and the Option or Stock Purchase Right shall terminate upon expiration of such period. For the purposes of this paragraph, the Option or Stock Purchase Right shall be considered assumed if, following the
merger or Change in Control, the option or right confers the right to purchase or receive, for each Share of Optioned Stock subject to the Option or Stock Purchase Right immediately prior to the merger or Change in Control, the consideration
(whether stock, cash, or other securities or property) received in the merger or Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or Change in Control is not solely common stock of the successor corporation or its Parent,
the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Option or Stock Purchase Right, for each Share of Optioned Stock subject to the Option or Stock Purchase
Right, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of common stock in the merger or Change in Control. 
 14. Time of Granting Options and Stock Purchase Rights. The date of grant of an Option or Stock Purchase Right shall, for all purposes,
be the date on which the Administrator makes the determination granting such Option or Stock Purchase Right, or such later date as is determined by the Administrator. Notice of the determination shall be given to each Service Provider to whom an
Option or Stock Purchase Right is so granted within a reasonable time after the date of such grant. 
  

 7. 

 15. Amendment and Termination of the Plan. 
 (a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 
 (b) Shareholder Approval. The Board shall obtain shareholder approval of any Plan amendment to the extent necessary and
desirable to comply with Applicable Laws. 
 (c) Effect of Amendment or Termination. No amendment,
alteration, suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of such termination. 
 16. Conditions Upon Issuance of Shares. 
 (a) Legal Compliance. Shares shall not be issued pursuant to the exercise of an Option unless the exercise of such Option and the issuance and delivery of such Shares shall comply with Applicable Laws
and shall be further subject to the approval of counsel for the Company with respect to such compliance. 
 (b) Investment Representations. As a condition to the exercise of an Option, the Administrator may require the person exercising such Option to represent and warrant at the time of any such exercise that the Shares are
being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. 
 17. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained. 
 18. Reservation of Shares. The Company, during the term of this Plan, shall at
all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
 19. Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company within twelve (12) months after the date the Plan is adopted. Such shareholder approval shall be obtained in the degree
and manner required under Applicable Laws.

 SECTION 3 
 SHARES SUBJECT TO THE PLAN 
 3.1 Stock Subject to the Plan. The maximum aggregate number of
Shares that may be optioned and sold under the Plan includes (a) any Shares which have been reserved but not issued under the Company’s 2002 Executive Stock Plan (the “Executive Plan”), (b) any Shares which have been
reserved but not issued under the Company’s 2002 Stock Plan (the “2002 Plan”), (c) any Shares returned to the Executive Plan or the 2002 Plan as a result of termination of options or repurchase of Shares issued under either such
plan, and (d) an annual increase to be added on the first day of the Company’s fiscal year beginning in 2005, equal to the lesser of (i) 1,250,000 Shares, (ii) 4% of the outstanding Shares on such date or (iii) an amount
determined by the Board. The Shares may be authorized, but unissued, or reacquired Common Stock. Shares shall not be deemed to have been issued pursuant to the Plan with respect to any portion of an Award that is settled in cash. Upon payment in
Shares pursuant to the exercise of an SAR, the number of Shares available for issuance under the Plan shall be reduced only by the number of shares actually issued in such payment. If the exercise price of an Option is paid by tender to the Company,
or attestation to the ownership, of Shares owned by the Participant, the number of shares available for issuance under the Plan shall be reduced by the gross number of shares for which the Option is exercised. 
 3.2 Lapsed Awards. If an Award expires or becomes unexercisable without having been exercised in full, or is surrendered pursuant to an Exchange
Program, the unpurchased Shares which were subject thereto will become available for future grant or sale under the Plan (unless the Plan has terminated); provided, however, that Shares that have actually been issued under the Plan, whether upon
exercise or grant of an Award, will not be returned to the Plan and will not become available for future distribution under the Plan, except that if unvested Shares are forfeited or repurchased by the Company at their original purchase price or, if
less than their original purchase price, their fair market value, such Shares will become available for future grant under the Plan. 
 3.3
Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company affecting the Shares occurs, the Administrator, to prevent dilution or enlargement of the benefits
or potential benefits intended to be made available under the Plan, shall adjust the number and class of Shares which may be delivered under the Plan, the number, class, and price of Shares covered by each outstanding Award, the numerical Share
limits of Section 5 and the number of Shares issuable pursuant to Section 10. 
 3.4 Share Reserve. The Company, during the
term of this Plan, will at all times reserve and keep available such number of Shares as will be sufficient to satisfy the requirements of the Plan. 
  

 5. 

 SECTION 4 
 ELIGIBILITY/ADMINISTRATION OF THE PLAN 
 4.1 Eligibility. Nonstatutory Stock Options, Stock
Purchase Rights, Restricted Stock, Stock Appreciation Rights, Performance Units and Performance Shares may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 
 4.2 Procedure. 
 4.2.1 Multiple
Administrative Bodies. Different Committees with respect to different groups of Service Providers may administer the Plan. 
 4.2.2
Section 162(m). To the extent that the Administrator determines it to be desirable to qualify Options granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, the Plan will be
administered by a Committee of two or more “outside directors” within the meaning of Section 162(m) of the Code. 
 4.2.3
Rule 16b-3. To the extent desirable to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule 16b-3. 
 4.2.4 Other Administration. Other than as provided above, the Plan will be administered by (A) the Board or (B) a Committee, which
committee will be constituted to satisfy Applicable Laws. 
 4.3 Powers of the Administrator. Subject to the provisions of the Plan,
and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion: (a) to determine the Fair Market Value; (b) to select the Service
Providers to whom Awards may be granted hereunder; (c) to determine the number of shares of Common Stock to be covered by each Award granted hereunder; (d) to approve forms of agreement for use under the Plan; (e) to determine the
terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder (such terms and conditions include, but are not limited to, the exercise price, the time or times when Awards may be exercised (which may be based on
performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or limitation regarding any Award or the shares of Common Stock relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, will determine); (f) to institute an Exchange Program; (g) to construe and interpret the terms of the Plan and awards granted pursuant to the Plan; (h) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of satisfying applicable foreign laws; (i) to modify or amend each Award (subject to Section 17.3 of the Plan), including the
discretionary authority to extend the post-termination exercisability period of Options longer than is otherwise provided for in the Plan; (j) to allow Participants to satisfy withholding tax obligations by electing to have the Company withhold
from the Shares to be issued upon exercise of an Award that number of Shares having a Fair Market Value equal to the minimum amount required to be withheld (the Fair Market Value of the Shares to be withheld will be determined on the date that the
amount of tax to be withheld is to be determined and all elections by a Participant to have Shares withheld for this purpose will be made in such form and under such conditions as the Administrator may deem necessary or advisable); (k) to
authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator; (l) allow a Participant to defer the receipt of the payment of cash or the delivery of
Shares that would otherwise be due to such Participant under an Award, and (m) to make all other determinations deemed necessary or advisable for administering the Plan. 
  

 6. 

 4.4 Effect of Administrator’s Decision. The Administrator’s decisions, determinations
and interpretations will be final and binding on all Participants and any other holders of Awards. 
 SECTION 5 
 STOCK OPTIONS 
 5.1
Limitations. 
 5.1.1 Incentive Stock Options may be granted only to Employees. 
 5.1.2 Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding
such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any
Parent or Subsidiary) exceeds $100,000, such Options will be treated as Nonstatutory Stock Options. For purposes of this Section 5.1.2, Incentive Stock Options will be taken into account in the order in which they were granted. The Fair Market
Value of the Shares will be determined as of the time the Option with respect to such Shares is granted. 
 5.1.3 The following limitations
will apply to grants of Options: 
 (a) No Service Provider will be granted, in any Fiscal Year, Options to purchase more than 500,000
Shares. 
 (b) In connection with his or her initial service as an Employee, a Service Provider may be granted Options to purchase up to an
additional 250,000 Shares, which will not count against the limit set forth in subsection (a) above. 
 (c) The foregoing limitations
will be adjusted proportionately in connection with any change described in Section 3.3. 
 (d) If an Option is cancelled in the same
Fiscal Year in which it was granted (other than in connection with a transaction described in Section 13), the cancelled Option will be counted against the limits set forth in subsections (a) and (b) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a cancellation of the Option and the grant of a new Option. 
 5.2
Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive Stock Option, the term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award
Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes
of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years from the date of grant or such shorter term as may be provided in the Award Agreement. 
  

 7. 

 5.3 Option Exercise Price and Consideration. 
 5.3.1 Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option will be determined by the
Administrator, subject to the following: 
 (a) In the case of an Incentive Stock Option 
 (i) granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting
power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than 110% of the Fair Market Value per Share on the date of grant. 
 (ii) granted to any Employee other than an Employee described in paragraph (i) immediately above, the per Share exercise price will be no less than
100% of the Fair Market Value per Share on the date of grant. 
 (b) In the case of a Nonstatutory Stock Option, the per Share exercise
price will be determined by the Administrator. In the case of a Nonstatutory Stock Option intended to qualify as “performance-based compensation” within the meaning of Section 162(m) of the Code, the per Share exercise price will be
no less than 100% of the Fair Market Value per Share on the date of grant. 
 (c) Notwithstanding the foregoing, Options may be granted with
a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of grant pursuant to a merger or other corporate transaction. 
 5.3.2 Waiting Period and Exercise Dates. At the time an Option is granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied
before the Option may be exercised. 
 5.3.3 Form of Consideration. The Administrator will determine the acceptable form of
consideration for exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely
of: (i) cash; (ii) check; (iii) promissory note; (iv) other Shares which, in the case of Shares acquired from the Company, (A) have been owned by the Participant for more than six (6) months on the date of surrender,
and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option will be exercised; (v) consideration received by the Company under a cashless exercise program
implemented by the Company in connection with the Plan; (vi) a reduction in the amount of any Company liability to the Participant, including any liability attributable to the Participant’s participation in any Company-sponsored deferred
compensation program or arrangement; (vii) any combination of the foregoing methods of payment; or (viii) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws. 
  

 8. 

 5.4 Exercise of Option. 
 5.4.1 Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 
 An Option will be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the
Award Agreement) from the person entitled to exercise the Option, and (ii) full payment for the Shares with respect to which the Option is exercised. Full payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Until
the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to
the Optioned Stock, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is
prior to the date the Shares are issued, except as provided in Section 3.3 of the Plan. 
 Exercising an Option in any
manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. 
 5.4.2 Termination of Relationship as a Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s
death or Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three (3) months following the Participant’s termination. If, on the date of
termination, the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If, after termination, the Participant does not exercise his or her Option within the time
specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 
 5.4.3
Disability of Participant. If a Participant ceases to be a Service Provider as a result of the Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to
the extent the Option is vested on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain
exercisable for twelve (12) months following the Participant’s termination. If, on the date of termination, the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert
to the Plan. If, after termination, the Participant does not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 
  

 9. 

 5.4.4 Death of Participant. If a Participant dies while a Service Provider, the Option may be
exercised following the Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the option be exercised later than the expiration of
the term of such Option as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such
beneficiary has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in
accordance with the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. If, at the time of death, Participant
is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time specified herein, the Option will terminate, and the Shares
covered by such Option will revert to the Plan. 
 SECTION 6 
 STOCK PURCHASE RIGHTS 
 6.1 Rights to Purchase. Stock Purchase Rights may
be issued either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer Stock Purchase Rights under the Plan, it will advise the
offeree in writing or electronically, by means of an Award Agreement, of the terms, conditions and restrictions related to the offer, including the number of Shares that the offeree will be entitled to purchase, the price to be paid, and the time
within which the offeree must accept such offer. The offer will be accepted by execution of an Award Agreement in the form determined by the Administrator. 
 6.2 Repurchase Option. Unless the Administrator determines otherwise, the Award Agreement will grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the
purchaser’s service with the Company for any reason (including death or Disability). The purchase price for Shares repurchased pursuant to the Award Agreement will be determined by the Administrator and may be paid by cancellation of any
indebtedness of the purchaser to the Company. The repurchase option will lapse at a rate determined by the Administrator. 
 6.3 Other
Provisions. The Award Agreement will contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. 
 6.4 Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser will have the rights equivalent to those of a stockholder,
and will be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Stock
Purchase Right is exercised, except as provided in Section 3.3 of the Plan. 
  

 10. 

 SECTION 7 
 RESTRICTED STOCK 
 7.1 Grant of Restricted Stock. Subject to the terms and provisions of the
Plan, the Administrator, at any time and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. The Administrator, in its sole discretion, will
determine the number of Shares to be granted to each Service Provider. 
 7.2 Restricted Stock Agreement. Each Award of Restricted
Stock will be evidenced by an Award Agreement that will specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator
determines otherwise, Shares of Restricted Stock will be held by the Company as escrow agent until the restrictions on such Shares have lapsed. 
 7.3 Transferability. Except as provided in this Section 7, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction.

 7.4 Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares of Restricted Stock
as it may deem advisable or appropriate. 
 7.5 Removal of Restrictions. Except as otherwise provided in this Section 7, Shares
of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction. The Administrator, in its discretion, may accelerate the time at
which any restrictions will lapse or be removed. 
 7.6 Voting Rights. During the Period of Restriction, Service Providers holding
Shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 
 7.7 Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of Restricted Stock will be entitled to receive all dividends and other distributions paid with respect
to such Shares unless otherwise provided in the Award Agreement. If any such dividends or distributions are paid in Shares, the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock
with respect to which they were paid. 
 7.8 Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the
Restricted Stock for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan. 
  

 11. 

 SECTION 8 
 STOCK APPRECIATION RIGHTS 
 8.1 Grant of SARs. Subject to the terms and conditions of the
Plan, an SAR may be granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. The Administrator may grant Affiliated SARs, Freestanding SARs, Tandem SARs, or any combination
thereof. 
 8.1.1 Number of Shares. The Administrator will have complete discretion to determine the number of SARs granted to any
Service Provider. 
 8.1.2 Exercise Price and Other Terms. The Administrator, subject to the provisions of the Plan, will have
complete discretion to determine the terms and conditions of SARs granted under the Plan. However, the exercise price of Tandem or Affiliated SARs will equal the Exercise Price of the related Option. 
 8.2 Exercise of Tandem SARs. Tandem SARs may be exercised for all or part of the Shares subject to the related Option upon the surrender of the
right to exercise the equivalent portion of the related Option. A Tandem SAR may be exercised only with respect to the Shares for which its related Option is then exercisable. With respect to a Tandem SAR granted in connection with an Incentive
Stock Option: (a) the Tandem SAR will expire no later than the expiration of the underlying Incentive Stock Option; (b) the value of the payout with respect to the Tandem SAR will be for no more than one hundred percent (100%) of the
difference between the Exercise Price of the underlying Incentive Stock Option and the Fair Market Value of the Shares subject to the underlying Incentive Stock Option at the time the Tandem SAR is exercised; and (c) the Tandem SAR will be
exercisable only when the Fair Market Value of the Shares subject to the Incentive Stock Option exceeds the Exercise Price of the Incentive Stock Option. 
 8.3 Exercise of Affiliated SARs. An Affiliated SAR will be deemed to be exercised upon the exercise of the related Option. The deemed exercise of an Affiliated SAR will not necessitate a reduction in the number
of Shares subject to the related Option. 
 8.4 Exercise of Freestanding SARs. Freestanding SARs will be exercisable on such terms and
conditions as the Administrator, in its sole discretion, will determine. 
 8.5 SAR Agreement. Each SAR grant will be evidenced by an
Award Agreement that will specify the exercise price, the term of the SAR, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 
 8.6 Expiration of SARs. An SAR granted under the Plan will expire upon the date determined by the Administrator, in its sole discretion, and set
forth in the Award Agreement. Notwithstanding the foregoing, the rules of Section 5.4 also will apply to SARs. 
 8.7 Payment of SAR
Amount. Upon exercise of an SAR, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 
 (a) The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times 
 (b) The
number of Shares with respect to which the SAR is exercised. 
  

 12. 

 At the discretion of the Administrator, the payment upon SAR exercise may be in cash, in Shares of
equivalent value, or in some combination thereof. 
 SECTION 9 
 PERFORMANCE UNITS AND PERFORMANCE SHARES 
 9.1 Grant of Performance
Units/Shares. Performance Units and Performance Shares may be granted to Service Providers at any time and from time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in
determining the number of Performance Units and Performance Shares granted to each Participant. 
 9.2 Value of Performance
Units/Shares. Each Performance Unit will have an initial value that is established by the Administrator on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of
grant. 
 9.3 Performance Objectives and Other Terms. The Administrator will set performance objectives in its discretion which,
depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to the Service Providers. The time period during which the performance objectives must be met will be called the
“Performance Period.” Each Award of Performance Units/Shares will be evidenced by an Award Agreement that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will
determine. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, or individual goals, applicable federal or state securities laws, or any other basis determined by the Administrator in its
discretion. 
 9.4 Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of Performance
Units/Shares will be entitled to receive a payout of the number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a function of the extent to which the corresponding performance objectives have
been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance objectives for such Performance Unit/Share. 
 9.5 Form and Timing of Payment of Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as practicable after
the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned
Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 
 9.6 Cancellation of
Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 
  

 13. 

 SECTION 10 
 FORMULA OPTION GRANTS TO OUTSIDE DIRECTORS 
 All grants of Options to Outside Directors pursuant to
this Section will be automatic and nondiscretionary and will be made in accordance with the following provisions: 
 10.1 Type of
Option. All Options granted pursuant to this Section will be Nonstatutory Stock Options and, except as otherwise provided herein, will be subject to the other terms and conditions of the Plan. 
 10.2 No Discretion. No person will have any discretion to select which Outside Directors will be granted Options under this Section or to
determine the number of Shares to be covered by such Options (except as provided in Section 3). Notwithstanding the foregoing, the Administrator, in its discretion, may grant an Option that is otherwise issuable to an Outside Director pursuant
to this Section 10 to the Outside Director’s employer and such employer shall be deemed an Outside Director for purposes of the Plan. 
 10.3 First Option. Each person who first becomes an Outside Director following the Registration Date will be automatically granted an Option to purchase 22,500 Shares (a “First Option”) on or about the date on which
such person first becomes an Outside Director, whether through election by the stockholders of the Company or appointment by the Board to fill a vacancy; provided, however, that an Inside Director who ceases to be an Inside Director but who remains
a Director will not receive a First Option. 
 10.4 Subsequent Option. Each Outside Director who also is the Chairman of the Board
will be automatically granted an Option to purchase 22,500 Shares and each Outside Director, other than the Chairman of the Board, will be automatically granted an Option to purchase 11,250 Shares (collectively referred to as a “Subsequent
Option”) on each date of the annual meeting of the stockholders of the Company beginning in 2004 or 2005, as the case may be, if as of such date, he or she will have served on the Board for at least the preceding six (6) months.

 10.5 Terms. The terms of each Option granted pursuant to this Section will be as follows: 
 10.5.1 The term of the Option will be ten (10) years. 
 10.5.2 The exercise price per Share will be 100% of the Fair Market Value per Share on the date of grant of the Option. 
 10.5.3 Subject to Section 13, the First Option will vest and become exercisable as to 1/3 of the Shares subject to the Option on each anniversary of its date of grant, provided that the Participant continues to
serve as a Service Provider on such dates. 
 10.5.4 Subject to Section 13, the Subsequent Option will vest and become exercisable as to
100% of the Shares subject to the Option on the anniversary of its date of grant, provided that the Participant continues to serve as a Service Provider on such date. 
 10.6 Amendment. The Administrator in its discretion may change the number of Shares subject to the First Options and Subsequent Options. 
  

 14. 

 SECTION 11 
 LEAVE OF ABSENCE 
 Unless the Administrator provides otherwise, vesting of Awards granted hereunder
will be suspended during any unpaid leave of absence. A Service Provider will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or (ii) transfers between locations of the Company or between the
Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed ninety days, unless reemployment upon expiration of such leave is guaranteed by statute or contract. If reemployment upon expiration of a leave
of absence approved by the Company is not so guaranteed, then three (3) months following the 91st day of such leave any Incentive Stock Option held by the Participant will cease to be treated as an Incentive Stock Option and will be treated for
tax purposes as a Nonstatutory Stock Option. 
 SECTION 12 
 TRANSFERABILITY OF AWARDS 
 Unless determined otherwise by the Administrator, an
Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Participant, only by the Participant. If
the Administrator makes an Award transferable, such Award will contain such additional terms and conditions as the Administrator deems appropriate. 
 SECTION 13 
 DISSOLUTION OR LIQUIDATION OR CHANGE IN CONTROL 
 13.1 Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify each
Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action. 
 13.2 Change in Control. In the event of a Change in Control, each outstanding Option, SAR and Stock Purchase Right will be assumed or an
equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. 
 In the event
that the successor corporation refuses to assume or substitute for the Option, SAR or Stock Purchase Right, the Participant will fully vest in and have the right to exercise the Option, SAR or Stock Purchase Right as to all of the Optioned Stock,
including Shares as to which it would not otherwise be vested or exercisable (subject to the consummation of the Change in Control). If an Option, SAR or Stock Purchase Right becomes fully vested and exercisable in lieu of assumption or substitution
in the event of a Change in Control, the Administrator will notify the Participant in writing or electronically that the Option, SAR or Stock Purchase Right will be fully vested and exercisable (subject to the consummation of the Change in Control)
for a period of fifteen (15) days from the date of such notice, and the Option, SAR or Stock Purchase Right will terminate upon the expiration of such period. 
  

 15. 

 With respect to Options, SARs and/or Stock Purchase Rights granted to an Outside Director that are
assumed or substituted for, if on the date of or following such assumption or substitution the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation
by the Participant, then the Participant will fully vest in and have the right to exercise the Option, SAR and/or Stock Purchase Rights as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable.

 For the purposes of this Section 13.2, the Option, SAR or Stock Purchase Right will be considered assumed if, following the Change in
Control, the option or right confers the right to purchase or receive, for each Share of Optioned Stock subject to the Option, SAR or Stock Purchase Right immediately prior to the Change in Control, the consideration (whether stock, cash, or other
securities or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders
of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not solely common stock of the successor corporation or its Parent, the Administrator may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of the Option, SAR or Stock Purchase Right, for each Share of Optioned Stock subject to the Option, SAR or Stock Purchase Right, to be solely common stock of the successor
corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in Control. 
 SECTION 14 
 NO EFFECT ON EMPLOYMENT OR SERVICE 
 Neither the Plan nor any Award will confer upon a Participant any right with respect to continuing the Participant’s relationship as a Service
Provider with the Company, nor will they interfere in any way with the Participant’s right or the Company’s right to terminate such relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 
 SECTION 15 
 DATE OF GRANT

 The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such
Award, or such other later date as is determined by the Administrator. Notice of the determination will be provided to each Participant within a reasonable time after the date of such grant. 
 SECTION 16 
 TERM OF PLAN 
 Subject to Section 20 of the Plan, the Plan will become effective following its adoption by the Board and on the day immediately preceding the date
of the Company’s firmly underwritten initial public offering. It will continue in effect for a term of ten (10) years unless terminated earlier under Section 17 of the Plan. 
  

 16. 

 SECTION 17 
 AMENDMENT AND TERMINATION OF THE PLAN 
 17.1 Amendment and Termination. The Administrator may
at any time amend, alter, suspend or terminate the Plan. 
 17.2 Stockholder Approval. The Company will obtain stockholder approval of
any Plan amendment to the extent necessary and desirable to comply with Applicable Laws. 
 17.3 Effect of Amendment or Termination.
No amendment, alteration, suspension or termination of the Plan will impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the
Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 
 SECTION 18 
 CONDITIONS UPON
ISSUANCE OF SHARES 
 18.1 Legal Compliance. Shares will not be issued pursuant to the exercise of an Award unless the exercise of
such Award and the issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 
 18.2 Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent
and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is
required. 
 SECTION 19 
 INABILITY TO OBTAIN AUTHORITY 
 The inability of the Company to obtain authority from any regulatory body having
jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to issue or sell such Shares as to
which such requisite authority will not have been obtained. 
  

 17. 

 SECTION 20 
 STOCKHOLDER APPROVAL 
 The Plan will be subject to approval by the stockholders of the Company within
twelve (12) months after the date the Plan is adopted. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws. 
 SECTION 21 
 WITHHOLDING 
 21.1 Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise thereof), the Company will have the
power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy federal, state, and local taxes (including the Participant’s FICA obligation) required to be withheld with respect to
such Award (or exercise thereof). 
 21.2 Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such
procedures as it may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (a) electing to have the Company withhold otherwise deliverable Shares, or (b) delivering to the
Company already-owned Shares having a Fair Market Value equal to the amount required to be withheld. The amount of the withholding requirement will be deemed to include any amount which the Administrator agrees may be withheld at the time the
election is made, not to exceed the amount determined by using the maximum federal, state or local marginal income tax rates applicable to the Participant with respect to the Award on the date that the amount of tax to be withheld is to be
determined. The Fair Market Value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld.
