 3.3. Interpretation. 
  
 Except as may otherwise be expressly reserved to the Board as provided herein, and with respect to any Option, except as may
otherwise be provided in the Option Agreement evidencing such Option, the Committee shall have all powers with respect to the administration of the Plan, including the interpretation of the provisions of the Plan and any Option Agreement (including,
without limitation, whether any particular termination of employment is for Cause), and all decisions of the Board or the Committee, as the case may be, shall be reasonable and made in good faith and shall be conclusive and binding on all
participants in the Plan. 
  
 3.4. Number of Shares.

  
 Subject to the provisions of Article X (relating to
adjustments upon changes in capital structure and other corporate transactions), the aggregate number of Shares with respect to which Options may be granted under the Plan shall not exceed the Reserved Shares. If and to the extent that Options
granted under the Plan terminate, are reduced in number, expire or are canceled without having been fully exercised, new Options may be granted under the Plan with respect to the Shares covered by the unexercised portion of such terminated, expired
or canceled Options. 
  
 3.5. Reservation of Shares.

  
 The number of Shares reserved for issuance upon the
exercise of Options granted under the Plan shall at no time be less than the maximum number of Shares which may be purchased at any time pursuant to outstanding Options. 
  
  
 ARTICLE IV 
  
 ELIGIBILITY 
  
 4.1. General. 
  
 Options may be granted under the Plan only to persons who are employees or
directors of, or consultants to, the Company or any of its Subsidiaries on the date of the grant. Options granted to consultants and non-employee directors shall be NSOs. Options granted to employees of the Company or any of its Subsidiaries shall
be, in the discretion of the Committee, either ISOs or NSOs on the date of the grant. 
  
 4.2. Exceptions. 
  
 Notwithstanding anything contained in Section 4.1 to the contrary, no ISO may be granted under the Plan to an employee who owns, directly or indirectly (within the meaning of Sections 422(b)(6) and 425(d) of the Code), stock possessing more
than 10% of the total combined voting power of all classes of stock of the Company or of its Parent, if any, or any of its Subsidiaries, unless (a) the Option Price of the Shares subject to such ISO is fixed at not less than 110% of the Fair Market
Value of such Shares on the date of the grant (as determined in accordance with Section 6.2), and (b) such ISO by its terms is not exercisable after the expiration of five years from the date it is granted. 
  

 5 








 ARTICLE V 
  

GRANT OF OPTIONS 
  
 5.1. General. 
  
 Subject to Section 5.6, Options may be granted under the Plan at any time and from time to time on or prior to the Termination Date. Subject to the
provisions of the Plan, the Committee shall have plenary authority, in its sole discretion, to determine: 
  

	 	(a)	The persons (from among the class of persons eligible to receive Options under the Plan) to whom Options shall be granted (the “Optionees”)


  

	 	(b)	The time or times at which Options shall be granted; and 

  

	 	(c)	The number of Shares for which an Option may be exercisable. 

  
 5.2. Option Agreements. 
  
 Each Option granted under the Plan shall be designated as an ISO or an NSO and shall be subject to the terms and conditions applicable to ISOs and/or NSOs
(as the case may be) set forth in the Plan. Each Option shall specify the number of Shares for which such Option shall be exercisable and the exercise price for such Shares. In addition, each Option shall be evidenced by a written agreement (an
“Option Agreement”) that shall be executed by the Company and the Optionee. 
  
 5.3. Vesting. 
  
 The Committee shall determine whether and to what extent any Options which are exercisable for Shares are also subject to vesting based upon the Optionee’s continued service to, or the performance of duties for, the Company and its
Subsidiaries. 
  
 5.4. No Evidence of Employment or
Service. 
  
 Nothing contained in the Plan or in any
Option Agreement shall confer upon any Optionee any right with respect to the continuation of his or her employment by or service with the Company or any of its Subsidiaries or interfere in any way with the right of the Company or any such
Subsidiary (subject to the terms of any separate agreement to the contrary) at any time to terminate such employment or service or to increase or decrease the compensation of the Optionee from the rate in existence at the time of the grant of an
Option. 
  
 5.5. Date of Grant. 
  
 The date of grant of an Option under this Plan shall be the date as of which
the Committee approves the grant; provided, however, that in the case of an ISO, the date of grant shall in no event be earlier than the date as of which the Optionee becomes an employee, director or consultant of the Company or one of its
Subsidiaries. 
  

 6 








 5.6. Shares. 
  
 Options shall be granted to purchase a specified number of Shares not to exceed, in the aggregate, the Reserved Shares.
Options may only be exercisable for whole Shares. Notwithstanding the foregoing, no Optionee shall be granted, in any calendar year, Options to purchase more than 1,000,000 Shares (the “Award Limit”); provided, however, that the
Award Limit shall not apply prior to the effective date of a Public Offering and, following the effective date of a Public Offering, the Award Limit shall not apply until the earliest of: (a) the first material modification of the Plan (including
any increase in the number of Reserved Shares); (b) the issuance of all of the Reserved Shares under the Plan; (c) the expiration of the Plan; (d) the first meeting of stockholders at which members of the Board are to be elected that occurs after
the close of the third calendar year following the calendar year in which occurred the first registration of an equity security of the Company under Section 12 of the Exchange Act; or (e) such other date required by Section 162(m) of the Code and
the rules and regulations promulgated thereunder. The Award Limit shall be adjusted proportionately in connection with any change in the Company’s capital structure as described in Article X. For purposes of this Section 5.6, if an Option is
canceled in the same calendar year it was granted (other than in connection with a transaction described in Article X), the canceled Option will be counted against the Award Limit. For this purpose, if the exercise price of an Option is reduced, the
transaction shall be treated as a cancellation of the Option and the grant of a new Option. 
  
  
 ARTICLE VI 
  
 OPTION PRICE 
  
 6.1. General. 
  
 The price (the “Option Price”) at which each Share may be purchased shall be determined by the Committee and set forth in the Option
Agreement; provided, however, that in the case of an ISO, such Option Price shall in no event be less than 100% (or 110% if Section 4.2(a) hereof is applicable) of the Fair Market Value of the Shares on the date of the grant (as determined in
accordance with Section 6.2). 
  
 6.2. Determination of Fair
Market Value. 
  
 Subject to the requirements of Section
422 of the Code regarding ISO’s, for purposes of the Plan, the “Fair Market Value” of a Share as of a particular date shall be determined as follows: 
  

 7 









	 	(a)	If such Shares are publicly traded, (i) the closing price on the business day immediately preceding such date if any trades were made on such business day and such information is
available, otherwise the average of the last bid and asked prices on the business day immediately preceding such date in the over-the-counter market as reported by the National Association of Securities Dealers Automated Quotations System
(“Nasdaq”) or (ii) if such Shares are then traded on the New York Stock Exchange or other national securities exchange, the closing price on the business day immediately preceding such date, if any trades were made on such business
day and such information is available, otherwise the average of the high and low prices on the business day immediately preceding such date on the New York Stock Exchange or principal other national securities exchange on which it is so traded; or


  

	 	(b)	If there is no public trading market for such Shares, the Fair Market Value of a Share shall be determined based upon the method set forth in the definition of “Fair Market
Value” contained in the Investor Rights Agreement; provided that if there is no public trading market for such Shares the Committee may, in its sole discretion, determine that Fair Market Value shall be equal to such other value as shall be
determined in good faith by the Committee. 

  
 ARTICLE VII 
  
 AUTOMATIC TERMINATION OF
OPTIONS 
  
 Each Option granted under the Plan shall
automatically terminate and shall become null and void and be of no further force or effect upon such date or dates set forth in the applicable Option Agreement, consistent with the terms of this Plan. Any Shares that are not acquired as a result of
an Option expiring without being fully exercised shall be available for award by the Committee to another eligible person. 
  
 ARTICLE VIII 
  
 LIMITATIONS ON ISOS; NOTICE TO OPTIONEES GRANTED ISOS 
  
 In accordance with Section 422(d) of the Code, to the extent that the aggregate Fair Market Value of all stock with respect to which incentive stock
options are exercisable for the first time by such Optionee during any calendar year (under all plans of the Company and its subsidiaries) exceeds $100,000, such ISOs shall be treated as NSOs. 
  
 Under certain circumstances, the exercise of an ISO may disqualify the holder
from recovering the favorable tax benefits ISOs offer. Therefore, the Company recommends that each Optionee holding an ISO consult with a competent tax advisor before taking any action with respect to his or her ISOs. 
  

 8 








 ARTICLE IX 
  
 PROCEDURE FOR EXERCISE 
  
 9.1. Payment. 
  
 An Optionee shall pay for the exercise of a Vested Option in United States currency by cash or personal or certified check payable to the Company in an
amount equal to the aggregate Option Price of the Shares with respect to which the Option is being exercised. 
  
 9.2. Notice. 
  
 An Optionee (or other person, as provided in Section 11.2) may exercise an Option (for the Shares represented thereby) granted under the Plan in whole or
in part (but for the purchase of whole Shares only), as provided in the Option Agreement evidencing his or her Option, by delivering a written notice (the “Notice”) to the Secretary of the Company. The Notice shall state:

  

	 	(a)	That the Optionee elects to exercise the Option; 

  

	 	(b)	The number of Shares with respect to which the Option is being exercised (the “Option Shares”); 

  

	 	(c)	The method of payment for the Option Shares (which method must be available to the Optionee under the terms of his or her Option Agreement); 

  

	 	(d)	The date upon which the Optionee desires to consummate the purchase (which date must be prior to the termination of such Option); 

  

	 	(e)	A copy of any election filed or intended to be filed by the Optionee with respect to such Option Shares pursuant to Section 83(b) of the Code; and 

  

	 	(f)	Any additional provisions consistent with the Plan as the Committee may from time to time require. 

  
 The exercise date of an Option shall be the date on which the Company receives the Notice from the Optionee. To the extent
required by the Investor Rights Agreement, such Notice shall also contain, to the extent such Optionee is not then a party to the Investor Rights Agreement, an Adoption Agreement, in form and substance satisfactory to the Board pursuant to which the
Optionee agrees to become a party to the Investor Rights Agreement. 
  
 9.3. Issuance of Certificates. 
  
 The
Company shall issue stock certificates in the name of the Optionee (or such other person exercising the Option in accordance with the provisions of Section 11.2), for the 

  

 9 








 
securities purchased upon exercise of an Option as soon as practicable after receipt of the Notice and payment of the aggregate Option Price for such
securities; provided that the Company may elect to not issue any fractional Shares upon the exercise of any Options (determining the fractional Shares after aggregating all Shares issuable to a single holder as a result of an exercise of an Option
for more than one Share) and in lieu of issuing such fractional Shares, shall pay the Optionee the Fair Market Value thereof. Neither the Optionee nor any person exercising an Option in accordance with the provisions of Section 11.2 shall have any
privileges as a stockholder of the Company with respect to any Shares of stock subject to an Option granted under the Plan until the date of issuance of stock certificates pursuant to this Section 9.3. 
  
 ARTICLE X 
  
 ADJUSTMENTS 
  
 10.1. Changes in Capital Structure. 
  
 If the Common Stock is changed by reason of a stock split, reverse stock
split, or stock combination, dividend (whether in the form of cash, Common Stock, other securities or other property), distribution, or other similar transaction or event or is converted into or exchanged for other securities as a result of a
merger, consolidation or reorganization (a “Reorganization”), the Board may make such adjustments in the number and kind of shares of stock available under the Plan as it shall determine to be necessary or appropriate to preserve to
an Optionee rights substantially proportionate to his rights existing immediately prior to such Reorganization or other transaction or event (but subject to the limitations and restrictions on such rights), including, without limitation, a
corresponding adjustment changing the number and kind of shares allocated to, and the Option Price of, each Option or portion thereof outstanding at the time of such change. Notwithstanding anything contained in the Plan to the contrary, in the case
of ISOs, no adjustment under this Section 10.1 shall be appropriate if such adjustment (a) would constitute a modification, extension or renewal of such ISOs within the meaning of Sections 422 and 424 of the Code, and the regulations promulgated by
the Treasury Department thereunder, or (b) would, under Section 422 of the Code and the regulations promulgated by the Treasury Department thereunder, be considered as the adoption of a new plan requiring stockholder approval. The Company will not,
in any event, permit the exercise price of any Option to be less than the par value of the Common Stock. 
  
 10.2. Special Rules. 
  
 Any adjustments referred to in Section 10.1 shall be made by the Board in its reasonable discretion and shall, absent manifest error, be conclusive and
binding on all persons holding any Options granted under the Plan. 
  
 10.3. Right to Include Vested Options upon a Realization Event. 
  
 Upon a Realization Event, the Company may, but is not obligated to, purchase each outstanding Vested Option for an amount equal to (a) the amount per share received in respect of the Shares sold in such transaction
constituting the Realization Event (b) less the Option Price thereof. 
  

 10 








 ARTICLE XI 
  
 RESTRICTIONS ON OPTIONS AND OPTION SHARES 
  
 11.1. Compliance With Securities Laws. 
  
 No Options shall be granted under the Plan, and no securities shall be issued and delivered upon the exercise of Options
granted under the Plan, unless and until the Company and/or the Optionee shall have complied with all applicable Federal or state registration, listing and/or qualification requirements and all other requirements of law or of any regulatory agencies
having jurisdiction. 
  
 The Committee in its discretion may, as a
condition to the exercise of any Option granted under the Plan, require an Optionee (a) to represent in writing that the securities received upon exercise of an Option are being acquired for investment and not with a view to distribution and (b) to
make such other representations and warranties as are deemed reasonably appropriate by the Company. Stock certificates representing securities acquired upon the exercise of Options that have not been registered under the Securities Act shall, if
required by the Committee, bear the legends as may be required by the Investor Rights Agreement and Option Agreement evidencing a particular Option. 
  
 11.2. Nonassignability of Option Rights. 
  
 No Option granted under this Plan shall be assignable or otherwise transferable by the Optionee, except by will or by the laws of descent and
distribution. An Option may be exercised during the lifetime of the Optionee only by the Optionee. If an Optionee dies, his or her Options shall thereafter be exercisable, during the period specified in the applicable Option Agreement (as the case
may be), by his or her executors or administrators to the full extent (but only to such extent) to which such Options were exercisable by the Optionee at the time of his or her death. 
  
 Before issuing any Shares upon exercise of Options to any person who is not already a party to the Investor Rights
Agreement, the Company shall obtain, in appropriate form, an executed Adoption Agreement from such person unless a Public Offering shall have already occurred. 
  

This Plan originally became effective as of November 28, 2001 (the “Effective Date”). This Plan, as amended and restated, became
effective as of December 11, 2003. 
  
 11.3. Restrictions
for the United Kingdom and Canada. 
  
 All Optionees who
are residents of the United Kingdom shall be subject to the additional restrictions set forth on Schedule I attached hereto. All Optionees who are residents of Canada shall be subject to the additional restrictions set forth on
Schedule II attached hereto. 
  

 11 








 ARTICLE XII

 No Options may be granted after the Termination Date. Any Option outstanding as of the Termination Date shall remain in effect until the earlier of the
exercise thereof and the Option Term with respect to such Option. 
  
 ARTICLE XIII 
  
 AMENDMENT OF PLAN

  
 The Plan may be modified or amended in any respect by the
Committee with the prior approval of the Board; provided, however, that the approval of the holders of a majority of the votes that may be cast by all of the holders of shares of common stock of the Company entitled to vote (voting together as a
single class, with each such holder entitled to cast one vote per share held by such holder) shall be obtained prior to any such amendment becoming effective if such approval is required by law or is necessary to comply with (a) regulations
promulgated by the Securities and Exchange Commission under Section 16(b) of the Exchange Act, (b) Section 422 of the Code or the regulations promulgated by the Treasury Department thereunder or (c) any rule or regulation promulgated by the New York
Stock Exchange (or, if applicable, the Nasdaq or other exchange or quotation system). Notwithstanding the foregoing, the Plan may not be modified or amended with respect to any existing Option Agreement if such change would impair the rights of the
applicable Optionee without the consent of such Optionee. 
  
 ARTICLE XIV 
  
 CAPTIONS 
  
 The use of captions in this Plan is for convenience. The captions are not
intended to provide substantive rights. 
  
 ARTICLE XV

  
 DISQUALIFYING DISPOSITIONS 
  
 If securities acquired by exercise of an ISO granted under this Plan are
disposed of within two years following the date of grant of the ISO or one year following the issuance of the securities to the Optionee (a “Disqualifying Disposition”), the holder of such securities shall, immediately prior to such
Disqualifying Disposition, notify the Company in writing of the date and terms of such Disqualifying Disposition and provide such other information regarding the Disqualifying Disposition as the Company may reasonably require. 
  

 12 








 ARTICLE XVI 
  
 WITHHOLDING TAXES 
  
 Whenever, under the Plan, securities are to be delivered to an Optionee upon exercise of an NSO (or an exercise of an ISO that will be taxed as an NSO),
such Optionee shall remit or, in appropriate circumstances, agree to remit when due, an amount sufficient to satisfy all current or estimated future Federal, state, local and foreign withholding tax and employment tax requirements relating thereto.
The Company shall deduct from such number of securities to be delivered to Optionee the number of securities necessary for the Company to satisfy all current or estimated future Federal, state, local and foreign withholding tax and employment tax
requirements relating thereto. 
  
 ARTICLE XVII 

 
 OTHER PROVISIONS 
  
 Each Option granted under the Plan may contain such other terms and
conditions not inconsistent with the Plan as may be determined by the Committee, in its sole discretion. Notwithstanding the foregoing, each ISO granted under the Plan shall include those terms and conditions which are necessary to qualify the ISO
as an “incentive stock option” within the meaning of Section 422 of the Code and the regulations thereunder and shall not include any terms or conditions which are inconsistent therewith. 
  
 ARTICLE XVIII 
  
 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, and vice-versa, as the context requires. 
  
 ARTICLE XIX 
  
 GOVERNING LAW 
  
 All questions concerning the
construction, interpretation and validity of this Plan and the instruments evidencing the Options granted hereunder shall be governed by and construed and enforced in accordance with the domestic laws of the State of New York, without giving effect
to any choice or conflict of law provision or rule (whether in the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York. In furtherance of the foregoing, the
internal law of the State of New York will control the interpretation and construction of this Plan, even if under such jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily
apply.

 SCHEDULE I 
  
 The following additional conditions shall apply to Optionees who are resident in the United Kingdom and subject to income tax under the
Income Tax and Corporation Taxes Act 1988. 
  

	1	Recovery of taxes 

  

	1.1	Without prejudice to the generality of Article XVI of the Plan, the exercise of an Option by a Optionee shall constitute the agreement and undertaking of the Optionee with the
Company (for itself and as trustee for its Subsidiaries) that he will forthwith upon written demand from the Company pay to the Company or as the Company may direct: 

  

	 	(a)	the amount of any income tax or other tax of the United Kingdom and primary national insurance contributions of the United Kingdom for which the Optionee may be liable or which may
be payable in respect of the Optionee as a consequence of such exercise and which the Company is required (whether such requirement is legally enforceable or not) to pay to the Inland Revenue or any other taxation authority; and


  

	 	(b)	the amount of any secondary national insurance contributions for which the Company is liable as a consequence of such exercise, other than any such amount or part thereof in respect
of which the Company has previously given notice in writing to the Optionee that it will not require payment under this paragraph 1.1; 

  
 and shall also constitute authority to the Company and every Subsidiary and former Subsidiary (in so far as not otherwise prohibited by law) to deduct any
amount so demanded which remains unpaid from payments otherwise payable to the Optionee, including but not limited to authority to deduct from wages or salary for the purposes of Part II of the Employment Rights Act 1996. 
  

	1.2	Without prejudice to the generality of paragraph 1.1, the Company may, as soon as practicable following receipt of the Notice in accordance with Section 9.2 of the Plan, notify the
Optionee in writing of the amount (if any) (“the Notified Sum”) which in its reasonable opinion it estimates the Company or any Subsidiary or former Subsidiary will be required (whether such requirement is legally enforceable or not) to
pay to the Inland Revenue or any other taxation authority in respect of: 

  

	 	(a)	income tax and primary national insurance contributions of the United Kingdom for which the Optionee is liable or which is payable in respect of the Optionee as a consequence of the
exercise of the Option; and 

  

	 	(b)	the amount of any secondary national insurance contributions which the Optionee is obliged to pay in accordance with paragraph 1.1(b). 

  
 Subject as hereafter provided, upon the giving of such a notice the Optionee
shall thereupon be bound and obliged to pay to the Company within seven days thereafter the 








 
Notified Sum and any obligation of the Company pursuant to Section 9.3 of the Plan shall be conditional upon receipt by the Company of the Notified Sum. In
the event that the Notified Sum proves to be an over-estimate, the Company shall on the date on which there is paid to the Inland Revenue or other taxation authority the sum actually so due repay to the Optionee or procure the repayment to the
Optionee of the excess of that part of the Notified Sum estimated to be due to the Inland Revenue or other taxation authority (as the case may be) not so paid. In the event that the Notified Sum is less than the aggregate amount which is required to
be so paid to the Inland Revenue or other taxation authority and which may be lawfully recovered from the Optionee, the Optionee shall forthwith on demand pay to the Company (or as it may direct) the balance of so much of the amount so paid as may
lawfully be recovered from the Optionee. The Board may in its absolute discretion accept security in form and substance satisfactory to the Board for payment to the Company of the Notified Sum and any further sum which may become due from the
Optionee as aforesaid in lieu of payment of the Notified Sum. 
  

	2	No compensation for the loss of rights 

  

	2.1	The terms of employment of a Optionee by the Company or its Subsidiaries shall not be affected by his participation in the Plan which shall not form part of such terms. In no
circumstances shall a Optionee in the event of cessation, lapse or alteration of any rights under the Plan be entitled to or claim against the Company or its Subsidiaries for any compensation for or in respect of any diminution or extinction of his
rights or benefits (actual or prospective) under any Options then held by him or otherwise in connection with the Plan. 

  

	3	Bankruptcy 

  

	3.1	Notwithstanding Rule 7.1 of the Plan, the Option shall terminate on the Optionee becoming bankrupt.

 SCHEDULE II 
  
 The following additional conditions shall apply to Optionees who are resident in Canada and subject to income tax under the Income Tax
Act (Canada). 
  

	1.	Notwithstanding Section 6.1 of the Plan, the Option Price shall in no event be less than 100 percent of the Fair Market Value of the Shares on the date the Option Agreement is made.


  

	2.	For the purposes of the Plan, an Optionee’s employment with the Company or a Subsidiary shall be considered to have terminated effective on the last day of the Optionee’s
actual and active employment with the Company or Subsidiary, whether such day is selected by agreement with the individual or unilaterally by the Company or Subsidiary and whether with or without advance notice to the Optionee. For the avoidance of
doubt, no period of notice that is given or that ought to have been given under applicable law in respect of such termination of employment will be utilized in determining entitlement under the Plan.
