the Board of Directors on April 21, 2005) 
  
 1.    Purposes of the Plan.  The purposes of this Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to the Employees

 2.    Definitions.  As used herein, the
following definitions shall apply: 
  

	 	(a)	 	“Administrator” shall mean the Board or any of its Committees appointed pursuant to Section 4 of the Plan. 

  

	 	(b)	 	“Applicable Laws” means the requirements relating to the administration of stock option plans under the corporate laws and securities regulations of applicable U.S.
state corporate laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Common Stock is listed or quoted and the applicable laws of any foreign country or jurisdiction where Options are, or will

	 	(d)	 	“Change in Control” shall mean a change in control of a nature that would be required to be reported in response to item 6(e) of Schedule 14A of Regulation 14A
promulgated under the Exchange Act as such Schedule, Regulation and Act were in effect on the date of adoption of this Plan by the Board, assuming that such Schedule, Regulation and Act applied to the Company, provided that such a change in control
shall be deemed to have occurred at such time as: 

  

	 	(i)	 	any “person” (as that term is used in Section 13(d) and 14(d)(2) of the Exchange Act) (other than the Company, a Subsidiary or an affiliate of the Company) becomes,
directly or indirectly, the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of securities representing a 33 1/3% or more of the combined voting power for election of members of the Board of the then outstanding voting securities of the Company or any successor of the Company; 

  

	 	(ii)	 	during any period of two consecutive years or less, individuals who at the beginning of such period constituted the Board of the Company cease, for any reason, to constitute at
least a majority of the Board, unless the election of nomination for election of each new member of the Board was approved by a vote of at least two-thirds of the members of the Board then still in office who were members of the Board at the
beginning of the period; 

  

	 	(iii)	 	the equity holders of the Company approve any merger or consolidation to which the Company is a party as a result of which the persons who were equity holders of the Company
immediately prior to the effective date of the merger or consolidation (and excluding, however, any shares held by any party to such merger or consolidation and their affiliates) shall have beneficial ownership of less than 50% of the combined
voting power for election of members of the Board (or equivalent) of the surviving entity following the effective date of such merger or consolidation; or 

  

	 	(iv)	 	the equity holders of the Company approve any merger or consolidation as a result of which the equity interests in the Company shall be changed, converted or exchanged (other than a
merger with a wholly-owned Subsidiary of the Company) or any liquidation of the Company or any sale or other disposition of all or substantially all of the assets of the Company. 

 However, in no event shall a Change in Control be deemed to have occurred with respect to a holder of a
Stock Right, if such holder is part of a purchasing group which consummates the Change in Control transaction. Such holder shall be deemed “part of a purchasing group” for purposes of the preceding sentence if he, she or it is either
directly or indirectly an equity participant in the purchasing group (except for (A) passive ownership of less than 3% of the stock of the purchasing group, or (B) ownership of equity participation in the purchasing group which is otherwise not
significant, as determined prior to the Change in Control by the Board).

the Company whether compensated for such services or not. 

  

	 	(j)	 	“Continuous Status as an Employee or Consultant” shall mean the absence of any interruption or termination of service as an Employee or Consultant. Continuous
Status as an Employee or Consultant shall not be considered interrupted in the case of sick leave, military leave, or any other leave of absence approved by the Administrator; provided that such leave is for a period of not more than 90 days or
reemployment upon the expiration of such leave is guaranteed by contract or statute. For purposes of this Plan, a change in status from Employee to Consultant or from Consultant to Employee will not constitute a termination of employment.

  

	 	(k)	 	“Director” shall mean a member of the Board. 

  

	 	(l)	 	“Disqualifying Disposition” shall mean any disposition (including any sale) of Common Stock before either (i) two years after the date the Employee was granted the

system for the last market trading day prior to the time of determination, as reported in The Wall Street Journal or such other source as the Administrator deems reliable; 

	 	(ii)	 	if the Common Stock is quoted on the NASDAQ System (but not on The National Market System thereof) or regularly quoted by a recognized securities dealer but selling prices are not
reported, its Fair Market Value shall be the mean between the high bid and low asked prices for the Common Stock for the last market trading day prior to the time of determination, as reported in The Wall Street Journal or such other source as the
Administrator deems reliable; or 

  

	 	(iii)	 	in the absence of an established market for the Common Stock, the Fair Market Value thereof shall be determined in good faith by the Board.

number of shares of Common Stock that are available for issuance under the Company’s 1996 Stock Option Plan as of the date of adoption of this Plan by the Company’s stockholders. Any such Shares may be issued as Incentive Stock Options,
Nonstatutory Stock Options or Stock Bonuses, or to persons or entities making purchases pursuant to Purchase Rights, so long as the number of Shares so issued does not exceed such aggregate number, as adjusted. If any Option granted under the Plan
should expire or become unexercisable for any reason without having been exercised in full or shall cease for any reason to be exercisable in whole or part, or if the Company shall reacquire any Shares issued pursuant to Stock Rights, the
unpurchased Shares that were subject thereto and any Shares so reacquired by the Company shall, unless the Plan shall have been terminated, become available for future grant under the Plan.

satisfy Applicable Laws. 

  

	 	(b)	 	Powers of the Administrator.  Subject to compliance with Applicable Laws, and further subject to the provisions of the Plan and in the case of a Committee, the
specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion: 

  

	 	(i)	 	to determine the Fair Market Value of the Common Stock, in accordance with Section 2(p) of the Plan; 

  

	 	(ii)	 	to select the Employees and Consultants to whom Stock Rights may from time to time be granted hereunder; 

  

	 	(iii)	 	to determine whether and to what extent Stock Rights are granted hereunder; 

  

	 	(iv)	 	to determine the number of shares of Common Stock subject to any Stock Right granted hereunder; 

  

	 	(v)	 	to approve forms of agreement for use under the Plan; 

  

	 	(vi)	 	to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Stock Right granted hereunder (including, but not limited to, the exercise price and any
restriction or limitation, or any vesting acceleration or waiver of forfeiture restrictions regarding any Option and/or the shares of Common Stock relating thereto, the purchase price of Shares subject to each Purchase Right, and the form of
consideration to be paid to the Company for the exercise of any Option or purchase of Shares with respect to a Stock Right, based in each case on such factors as the Administrator shall determine, in its sole discretion); 

 

	 	(vii)	 	to determine (subject to Section 10) the time or times when each Option shall become exercisable and the duration of the exercise period; 

  

	 	(viii)	 	to determine whether restrictions such as repurchase options are to be imposed on Shares subject to Options, Stock Bonuses and Purchase Rights and the nature of such restrictions,
if any; 

  

	 	(ix)	 	to determine whether, to what extent and under what circumstances Common Stock and other amounts payable with respect to an award under this Plan shall be deferred either
automatically or at the election of the participant (including providing for and determining the amount, if any, of any deemed earnings on any deferred amount during any deferral period); 

  

	 	(x)	 	to construe and interpret the terms of the Plan and awards granted pursuant to the Plan; 

	 	(xi)	 	to institute an option exchange program; and 

  

	 	(xii)	 	to make all other determinations necessary or advisable for the administration of the Plan. 

  

	 	(c)	 	Effect of Administrator’s Decision.  All decisions, determinations and interpretations of the Administrator shall be final and binding on all holders of any
Stock Rights. The interpretation and construction by the Administrator of any provisions of the Plan or of any Stock Right granted under it shall be final unless otherwise determined by the Board. The Administrator may from time to time adopt such
rules and regulations for carrying out the Plan as it may deem best. No member of the Board or any Committee shall be liable for any action or determination made in good faith with respect to the Plan or any Stock Right granted under it.

  
 5.    Eligibility.

  

	 	(a)	 	Nonstatutory Stock Options, Stock Bonuses and Purchase Rights may be granted to Employees and Consultants. Incentive Stock Options may be granted only to Employees. An Employee or
Consultant who has been granted a Stock right may, if he or she is otherwise eligible, be granted additional Stock Rights. 

  

	 	(b)	 	Each Option shall be designated in the written option agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designations, to
the extent that the aggregate Fair Market Value of Options that are exercisable for the first time by an Optionee during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, (or such higher value as
permitted under Code section 422 at the time of such determination), such excess Options shall be treated as Nonstatutory Stock Options. 

  

	 	(c)	 	For purposes of Section 5(b) hereof, Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted. 

  

	 	(d)	 	The Plan shall not confer upon any holder of a Stock Right any right with respect to the continuation of an employment or consulting relationship with the Company, nor shall such
Stock Right interfere in any way with his or her right or the Company’s right to terminate his or her employment or consulting relationship at any time, with or without cause. 

  

	 	(e)	 	The terms of any Stock Right shall comply with Applicable Laws. 

  
 6.    Term of Plan.  The Plan shall become effective upon the earlier to occur of its adoption by the Board or its
approval by the stockholders of the Company (the “Effective Date”). It shall continue in effect for a term of ten (10) years, unless sooner terminated under Section 15 of the Plan. 
  
 7.    Granting of Stock Rights.  Stock
Rights may be granted under the Plan at any time after the Effective Date, as set forth in Section 6, and prior to 10 years thereafter. The date of grant of a Stock Right under the Plan will be the date specified by the Administrator at the time it
grants the Stock Right; provided, however, that such date shall not be prior to the date on which the Administrator acts. 
  
 8.    Term of Option.  The term of each Option shall be the term stated in the Option Agreement; provided,
however, that in the case of an Incentive Stock Option, the term shall be no more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. However, 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 thereof or such shorter term as may be provided in the Option Agreement. 
  
 9.    Option Exercise Price and Consideration. 
  

	 	(a)	 	 The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Administrator, but shall be
no less than 100% of the Fair 

	 	 
Market Value on the date of grant; provided, that, in the case of an Incentive Stock Option granted to an Employee who, at the time of the
grant of such Incentive Stock 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 per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant. 

  

	 	(b)	 	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) and may consist entirely of (1) cash, (2) check, (3) other Shares that (x) in the case of Shares acquired upon exercise of an Option either have been owned by the Optionee for more
than six months on the date of surrender or were not acquired, directly or indirectly, from the Company, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be
exercised, (4) authorization from the Company to retain from the total number of Shares as to which the Option is exercised that number of Shares having a Fair Market Value on the date of exercise equal to the exercise price for the total number of
Shares as to which the Option is exercised, (5) delivery of a properly executed exercise notice together with irrevocable instructions to a broker to deliver promptly to the Company the amount of sale or loan proceeds required to pay the exercise
price, (6) any combination of the foregoing methods of payment, or (7) as determined by the Administrator, such other consideration and method of payment for the issuance of Shares to the extent permitted under Applicable Laws. No Optionee shall
receive financial assistance from the Company in connection with the exercise of any Option and the purchase price of the Common Stock issuable pursuant to any Option shall be paid in full prior to the issuance of such Common Stock. 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 Stockholder.  Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the
Administrator, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan. 

  
 An Option may not be exercised for a fraction of a Share. 
  
 An Option shall be deemed to be exercised when written notice
of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company.
Full payment may, as authorized by the Administrator, consist of any consideration and method of payment allowable under Section 9(b) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly
authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect thereto, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such stock certificate promptly upon exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except
as provided in Section 14 of the Plan. 
  
 Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be 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 Status as an Employee or Consultant.  In the event of termination of an Optionee’s Continuous Status as an Employee or
Consultant for any reason other than by reason of death or disability, such Optionee may, but only within thirty (30) days (or such other period of time, not 

	 	 
exceeding three (3) months in the case of an Incentive Stock Option or six (6) months in the case of a Nonstatutory Stock Option, as is determined by the
Administrator, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option) after the date of such termination (but in no event later than the date of expiration of the term of such Option as set
forth in the Option Agreement), exercise his or her Option to the extent that he or she was entitled to exercise it at the date of such termination. To the extent that the Optionee was not entitled to exercise the Option at the date of such
termination, or if the optionee does not exercise such Option (which he or she was entitled to exercise) within the time specified herein, the Option shall terminate. 

  

	 	(c)	 	Disability of Optionee.  Notwithstanding the provisions of Section 10(b) above, in the event of termination of an Optionee’s Continuous Status as an Employee
or Consultant as a result of his or her disability, all unvested options under the Optionee’s Option shall immediately vest, and he or she may, but only within twelve (12) months (or such shorter period of time as is determined by the
Administrator, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option) from the date of such termination (but in no event later than the date of expiration of the term of such Option as set
forth in the Option Agreement), exercise his or her Option. To the extent that he or she does not exercise such Option within the time specified herein, the Option shall terminate. 

  

	 	(d)	 	Death of Optionee.  In the event of the death of an Optionee: 

  

	 	(i)	 	during the term of the Option while such Optionee is at the time of his death an Employee or Consultant of the Company and who shall have been in Continuous Status as an Employee or
Consultant since the date of grant of the Option, all unvested options under the Optionee’s Option shall immediately vest, and the Option may be exercised, at any time within twelve (12) months (or such shorter period of time as is determined
by the Administrator, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option) following the date of death (but in no event later than the date of expiration of the term of such Option as set
forth in the Option Agreement), by the Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance; or 

  

	 	(ii)	 	within thirty (30) days (or such other period of time not exceeding three (3) months as is determined by the Administrator, with such determination in the case of an Incentive Stock
Option being made at the time of grant of the Option) after the termination of Continuous Status as an Employee or Consultant, the Option may be exercised, at any time within twelve (12) months following the date of death (but in no event later than
the date of expiration of the term of such Option as set forth in the Option Agreement), by the Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent of the right to
exercise that had accrued at the date of termination. 

  
 11.    Withholding Taxes.  Upon the exercise of a Nonstatutory Stock Option, or the grant of a Stock Bonus or Purchase Right for less than the Fair Market Value of the Common Stock, the making of a
Disqualifying Disposition, the vesting of restricted Common Stock acquired on the exercise of a Stock Right hereunder or the surrender of an Option pursuant to Section 17, the Company, in accordance with Section 3402(a) of the Code and any
applicable state statute or regulation, may require the Optionee, Stock Bonus recipient or purchaser to pay to the Company additional withholding taxes in respect of the amount that is considered compensation includable in such person’s gross
income. With respect to any such event, the Administrator in its discretion may condition such event on the payment by the Optionee, Stock Bonus recipient or purchaser of any such additional withholding taxes. The Company shall not be required to
issue any Shares under the Plan until such obligations are satisfied. 
  
 12.    Satisfaction of Withholding Tax Obligations.  At the sole and absolute discretion of the Administrator, the holders of Stock Rights may satisfy withholding obligations as provided in this Section.
When a holder of a 

 
Stock Right incurs tax liability in connection with the exercise or receipt of Stock Rights, the making of a Disqualifying Disposition, or the vesting of
restricted Common Stock acquired on the exercise of a Stock Right hereunder, which tax liability is subject to tax withholding under applicable tax laws, and the holder of such Stock Right is obligated to pay the Company an amount required to be
withheld under applicable tax laws, the holder of such Stock Right may satisfy the withholding tax obligation by one or some combination of the following methods: (a) by cash payment; or (b) out of his or her current compensation; (c) if permitted
by the Administrator, in its discretion, by surrendering to the Company Shares that (i) in the case of Shares previously acquired from the Company, have been owned by such holder for more than six (6) months on the date of surrender, and (ii) have a
Fair Market Value on the date of surrender equal to or less than such holder’s marginal tax rate times the ordinary income recognized; or (d) by electing to have the Company withhold from the Shares to be issued upon exercise of the Stock Right
that number of Shares having a Fair Market Value equal to the amount required to be withheld. For this purpose, the Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be
determined. 
  
 All elections by any holder of Stock Rights to
have Shares withheld to satisfy tax withholding obligations shall be made in writing in a form acceptable to the Administrator. 
  
 13.    Non-Transferability of Stock Rights.  Unless determined otherwise by the Administrator, a Stock Right 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 holder, only by the holder of such Stock Right. If the
Administrator makes a Stock Right transferable, such Stock Right shall contain such additional terms and conditions as the Administrator deems appropriate. 
  
 14.    Adjustments Upon Changes in Capitalization or Merger. 
  

	 	(a)	 	Changes in Capitalization.  Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding
Stock Right, the number of shares of Common Stock that have been authorized for issuance under the Plan but as to which no Stock Rights have yet been granted or which have been returned to the Plan upon cancellation or expiration of a Stock Right,
and the price per share of Common Stock covered by each such outstanding Stock Right, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split,
stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to a Stock Right. 

  

	 	(b)	 	Dissolution or Liquidation.  In the event of the proposed dissolution or liquidation of the Company, the Board shall notify the holder of a Stock Right as soon as
practicable prior to the effective date of such proposed action. To the extent it has not been previously exercised, such Stock Right will terminate immediately prior to the consummation of such proposed action. 

  

	 	(c)	 	 Acceleration upon Change in Control.  In the event of a Change in Control of the Company, all outstanding Stock Rights granted under the Plan and
any restricted Shares acquired on the exercise of a Stock Right shall become vested and immediately and fully exercisable, and all forfeiture restrictions shall be waived, and may either (i) be assumed or an equivalent option or right shall be
substituted by such successor corporation or a Parent or Subsidiary of such successor corporation or (ii) terminate ten (10) days after the Administrator shall notify the holder of such vesting and termination. For the purposes of this Section, the
Stock Right shall be considered 

	 	 
assumed if, following the merger or sale of assets, the Stock Right confers the right to purchase or receive, for each Share subject to the Stock Right
immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets 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 sale
of assets 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 Stock Right, for each Share
subject to the Stock 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 sale of assets.

  

	 	(d)	 	Certain Distributions.  In the event of any distribution to the Company’s stockholders of securities of any other entity or other assets (other than dividends
payable in cash or stock of the Company) without receipt of consideration by the Company, the Administrator may, in its discretion, appropriately adjust the price per share of Common Stock covered by each outstanding Stock Right to reflect the
effect of such distribution. 

  
 15.    Amendment and Termination of the Plan. 
  

	 	(a)	 	Amendment and Termination.  The Board may amend or terminate the Plan from time to time in such respects as the Board may deem advisable. 

 

	 	(b)	 	Stockholder Approval.  The Company shall obtain stockholder approval of any material Plan amendment (including but not limited to any downward repricing of
outstanding options or increase in the total number of Shares that may be issued under the Plan) and to the extent necessary and desirable to comply with Applicable Laws. 

  

	 	(c)	 	Effect of Amendment or Termination.  Any such amendment or termination of the Plan shall not adversely alter or impair the rights of a holder of Stock Rights,
without his, her or its consent, under any Stock Right previously granted. 

  
 16.    Conditions Upon Issuance of Shares.  Shares shall not be issued pursuant to the exercise of a Stock Right unless the exercise of such Stock Right and the issuance and
delivery of such Shares pursuant thereto shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. As a condition to the exercise of a Stock Right, the Company may
require the person exercising such Stock Right 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 by any of the aforementioned relevant provisions of law. 
  
 17.    Surrender of Stock Rights for Cash or Stock.  The Administrator may, in its sole and absolute discretion and
subject to such terms and conditions as it deems appropriate, accept the surrender by a holder of a Stock Right granted to him, her or it under the Plan and authorize payment in consideration therefor of an amount equal to the difference between the
purchase price payable for the Shares under the instrument granting the Stock Right and the Fair Market Value of the Shares subject to the Stock Right (determined as of the date of such surrender of the Stock Right). Such payment shall be made in
shares of Common Stock valued at Fair Market Value on the date of such surrender, or in cash, or partly in such shares of Common Stock and partly in cash as the Administrator shall determine. The surrender shall be permitted only if the
Administrator determines that such surrender is consistent with the purpose set forth in Section 1, and only to the extent that the Stock Right is exercisable under the terms of this Plan on the date of surrender. In no event shall a holder
surrender his or her Stock Right under this Section if the Fair Market Value of the Shares on the date of such surrender is less than the purchase price payable for the Shares subject to the Stock Right. Any Incentive Stock Option surrendered
pursuant to the provisions of this Section shall be deemed to have been converted into a Nonstatutory Stock Option immediately prior to such surrender. 

 18.    Conversion of Incentive Stock Options into Nonstatutory Stock Options;
Termination.  The Administrator, with consent of any Optionee, may in its discretion take such actions as may be necessary to convert and Optionee’s Incentive Stock Option(s) or any installments or portions of installments thereof
that have not been exercised on the date of conversion into Nonstatutory Stock Option(s) at any time prior to the expiration of such Incentive Stock Option(s). These actions may include, but not be limited to, accelerating the exercisability or
extending the exercise period of the appropriate installments of Optionee’s Options. At the time of such conversion, the Administrator, with the consent of the Optionee, may impose these conditions on the exercise of the resulting Nonstatutory
Stock Option(s) as the Administrator in its discretion may determine, provided that the conditions shall be consistent with the Plan. Nothing in the Plan shall be deemed to give any Optionee the right to have such Optionee’s Incentive Stock
Option(s) converted into Nonstatutory Stock Option(s), and no conversion shall occur until and unless the Administrator takes appropriate action. The Administrator, with the consent of the Optionee, may also terminate any portion of any Incentive
Stock Option that has not been exercised at the time of the termination. 
  
 19.    Notice to Company of Disqualifying Disposition.  Each Employee who receives an Incentive Stock Option must agree to notify the Company in writing immediately after the
employee makes a Disqualifying Disposition of any Common Stock acquired pursuant to the exercise of an Incentive Stock Option. 
  
 20.    Reservation of Shares.  The Company, during the term of this Plan, will at all times reserve and keep
available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 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. 
  
 21.    Form of Stock Rights
Agreement.  Stock Rights shall be evidenced by written agreements in such forms as the Board shall approve. 
  
 22.    Option Grants to Non-Employee Directors.  Upon joining the Board, each non-Employee Director shall
receive a one-time grant of an Option to purchase 20,000 shares (subject to adjustment for splits, recapitalizations and the like) of Common Stock at the Fair Market Value as of the date of grant, vesting ratably over 36 months. Each non-Employee
Director shall be granted an annual Option to purchase 15,000 shares (subject to adjustment for splits, recapitalizations and the like) of Common Stock at the Fair Market Value as of the date of grant, vesting ratably over 12 months.

 SALIX PHARMACEUTICALS, LTD. 
  
 2005 STOCK PLAN 
 STOCK OPTION AGREEMENT 
  
 1.    Grant of Option.  Salix Pharmaceuticals, Ltd., a Delaware corporation (the “Company”), hereby grants to the Optionee named in the Notice of Grant (the “Optionee”),
an option (the “Option”) to purchase a total number of shares of Common Stock (the “Shares”) set forth in the Notice of Grant, at the exercise price per share set forth in the Notice of Grant (the “Exercise
Price”) subject to the terms, definitions and provisions of the Salix Pharmaceuticals, Ltd. 2005 Stock Plan (the “Plan”) adopted by the Company, which is incorporated herein by reference. Unless otherwise defined herein,
the terms defined in the Plan shall have the same defined meanings in this Option. 
  
 If designated an Incentive Stock Option, this Option is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Code, or any successor provision. 
  
 2.    Exercise of Option.  This Option
shall be exercisable during its term in accordance with the Vesting Schedule set out in the Notice of Grant and with the provisions of Section 10 of the Plan as follows. 
  

	 	(i)    Right	 	to Exercise. 

  

	 	(a)	 	This Option may not be exercised for a fraction of a share. 

  

	 	(b)	 	In the event of Optionee’s death, disability or other termination of employment or consulting relationship, the exercisability of the Option is governed by Sections 5, 6 and 7
below, subject to the limitation contained in subsection 2(i)(c). 

  

	 	(c)	 	In no event may this Option be exercised after the date of expiration of the term of this Option as set forth in the Notice of Grant. 

  

	 	(ii)    Method	 	of Exercise.  This Option shall be exercisable by written notice (in the form attached as Exhibit A) which shall state the election to exercise the
Option, the number of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan. Such written notice shall be signed by the Optionee and shall be delivered in person or by certified mail to the Chief Financial Officer of the Company. The written notice shall be accompanied by payment of
the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price. 

  
 No Shares will be issued pursuant to the exercise of an Option unless such issuance and such exercise shall comply with all
relevant provisions of law and the requirements of any stock exchange upon which the Shares may then be listed. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to the Optionee on the date on which the
Option is exercised with respect to such Shares. 
  
 3.    Method of Payment.  Payment of the Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee: 
  

	 	(i)	 	cash; or 

  

	 	(ii)	 	check; or 

  

	 	(iii)	 	surrender of other shares of Common Stock of the Company which (a) in the case of Shares acquired pursuant to the exercise of a Company option, either have been owned by the
Optionee for more than six (6) months on the date of surrender or were not acquired, directly or indirectly, from the Company, and (b) have a fair market value on the date of surrender equal to the aggregate Exercise Price for the total number of
Shares as to which the Option is being exercised; or 

	 	(iv)	 	authorization from the Company to retain from the total number of Shares as to which the Option is exercised that number of Shares having a fair market value on the date of exercise
equal to the aggregate exercise price for the total number of Shares as to which the Option is exercised; or 

  

	 	(v)	 	delivery of a properly executed exercise notice together with irrevocable instructions to a broker to deliver promptly to the Company the amount of sale or loan proceeds required to
pay the exercise price; or 

  

	 	(vi)	 	any combination of the foregoing methods of payment. 

  
 4.    Restrictions on Exercise.  This Option may not be exercised until such time as the Plan has been approved by
the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such Shares would constitute a violation of any applicable federal or state securities or other law or regulation,
including any rule under Part 207 of Title 12 of the Code of Federal Regulations (“Regulation G”) as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company may require Optionee to make
any representation and warranty to the Company as may be required by any applicable law or regulation. 
  
 5.    Termination of Relationship.  In the event of termination of Optionee’s Continuous Status as an Employee
or Consultant, Optionee may, to the extent otherwise so entitled at the date of such termination (the “Termination Date”), exercise this Option during the Termination Period set out in the Notice of Grant. To the extent that
Optionee was not entitled to exercise this Option at the Termination Date, or if Optionee does not exercise this Option within the time specified herein, the Option shall terminate. 
  
 6.    Disability of Optionee.  Notwithstanding the provisions of Section 5 above, in
the event of termination of Optionee’s Continuous Status as an Employee or Consultant as a result of his or her disability, all unvested options under this Option shall immediately vest, and Optionee may, but only within twelve (12) months from
the date of termination of employment (but in no event later than the date of expiration of the term of this Option as set forth in Section 9 below), exercise this Option. To the extent that Optionee does not exercise such Option within the time
specified herein, the Option shall terminate. 
  
 7.    Death of Optionee.  Notwithstanding the provisions of Section 5 above, in the event of the death of Optionee: 
  

	 	(i)	 	during the term of this Option and while an Employee or Consultant of the Company and having been in Continuous Status as an Employee or Consultant since the date of grant of the
Option, all unvested options under this Option shall immediately vest, and the Option may be exercised at any time within twelve (12) months following the date of death (but in no event later than the date of expiration of the term of this Option as
set forth in Section 9 below), by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance; or 

  

	 	(ii)	 	within thirty (30) days after the termination of Optionee’s Continuous Status as an Employee or Consultant, the Option may be exercised, at any time within twelve (12) months
following the date of death (but in no event later than the date of expiration of the term of this Option as set forth in Section 9 below), by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or
inheritance, but only to the extent of the right to exercise that had accrued at the date of termination. 

  
 8.    Non-Transferability of Option.  This option may not be transferred in any manner otherwise than by will or by
the laws of descent or distribution and may be exercised during the lifetime of Optionee only by Optionee. The terms of this Option shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
  
 9.    Term of Option.  This Option may
be exercised only within the term set out in the Notice of Grant, and may be exercised during such term only in accordance with the Plan and the terms of this Option. The limitations set out in Section 8 of the Plan regarding Options designated as
Incentive Stock Options and Options granted to more than ten percent (10%) stockholders shall apply to this Option. 

 10.    Taxation Upon Exercise of Option.  Optionee understands that,
upon exercising a Nonstatutory Stock Option, he or she will recognize income for tax purposes in an amount equal to the excess of the then fair market value of the Shares over the exercise price. However, the timing of this income recognition may be
deferred for up to six months if Optionee is subject to Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). If the Optionee is an employee, the Company will be required to withhold from
Optionee’s compensation, or collect from Optionee and pay to the applicable taxing authorities, an amount equal to a percentage of this compensation income. Additionally, the Optionee may at some point be required to satisfy tax withholding
obligations with respect to the disqualifying disposition of an Incentive Stock Option. The Optionee shall satisfy his or her tax withholding obligation arising upon the exercise of this Option by one or some combination of the following methods:
(i) by cash payment; (ii) out of Optionee’s current compensation; (iii) if permitted by the Administrator, in its discretion, by surrendering to the Company Shares which (a) in the case of Shares previously acquired from the Company, have been
owned by the Optionee for more than six months on the date of surrender, and (b) have a fair market value on the date of surrender equal to or greater than Optionee’s marginal tax rate times the ordinary income recognized; (iv) by electing to
have the Company withhold from the Shares to be issued upon exercise of the Option that number of Shares having a fair market value equal to the amount required to be withheld. For this purpose, the fair market value of the Shares to be withheld
shall be determined on the date that the amount of tax to be withheld is to be determined (the “Tax Date”). 
  
 If the Optionee is subject to Section 16 of the Exchange Act (an “Insider”), any surrender of previously owned Shares to satisfy tax
withholding obligations arising upon exercise of this Option must comply with the applicable provisions of Rule 16b-3 promulgated under the Exchange Act (“Rule 16b-3”) and shall be subject to such additional conditions or
restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. 
  
 All elections by an Optionee to have Shares withheld to satisfy tax withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions: 
  

	 	(1)	 	the election must be made on or prior to the applicable Tax Date; 

  

	 	(2)	 	once made, the election shall be irrevocable as to the particular Shares of the Option as to which the election is made; 

  

	 	(3)	 	all elections shall be subject to the consent or disapproval of the Administrator; and 

  

	 	(4)	 	if the Optionee is an Insider, the election must comply with the applicable provisions of Rule 16b-3 and shall be subject to such additional conditions or restrictions as may be
required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. 

  
 11.    Tax Consequences.  Set forth below is a brief summary as of the date of this Option of some of the U.S.
federal and North Carolina tax consequences of exercise of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE
EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 
  

	 	(i)	 	Exercise of ISO.  If this Option qualifies as an ISO, there will be no regular U.S. federal income tax liability or North Carolina income tax liability upon the
exercise of the Option, although the excess, if any, of the fair market value of the Shares on the date of exercise over the Exercise Price will be treated as an adjustment to the alternative minimum tax for federal tax purposes and may subject the
Optionee to the alternative minimum tax in the year of exercise. 

  

	 	(ii)	 	 Exercise of Nonstatutory Stock Option.  If this Option does not qualify as an ISO, there may be a regular U.S. federal income tax liability and
North Carolina income tax liability upon the exercise of the Option. The Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the fair market value of the Shares on
the date of exercise over the Exercise Price. If Optionee is an employee, the Company 

	 	 
will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise. 

  

	 	(iii)	 	Disposition of Shares.  In the case of an NSO, if Shares are held for at least one year, any gain realized on disposition of the Shares will be treated as long-term
capital gain for U.S. federal and North Carolina income tax purposes. In the case of an ISO, if Shares transferred pursuant to the Option are held for at least one year after exercise and are disposed of at least two years after the Date of Grant,
any gain realized on disposition of the Shares will also be treated as long-term capital gain for U.S. federal and North Carolina income tax purposes. If Shares purchased under an ISO are disposed of within such one-year period or within two years
after the Date of Grant, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the difference between the Exercise Price and the lesser of (a) the fair market value of the
Shares on the date of exercise, or (b) the sale price of the Shares. 

  

	 	(iv)	 	Notice of Disqualifying Disposition of ISO Shares.  If the Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise disposes of any of the
Shares acquired pursuant to the ISO on or before the later of (a) the date two years after the Date of Grant, or (b) the date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition.
Optionee agrees that Optionee may be subject to income tax withholding by the Company on the compensation income recognized by the Optionee from the early disposition by payment in cash or out of the current earnings paid to the Optionee.

  
 12.    Successors and
Assigns.  The Company may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on
transfer herein set forth, this Agreement shall be binding upon Optionee and his or her heirs, executors, administrators, successors and assigns. 
  
 13.    Interpretation.  Any dispute regarding the interpretation of this Agreement shall be submitted by Optionee or
by the Company forthwith to the Administrator, who shall review such dispute at its next regular meeting. The resolution of such a dispute by the Administrator, shall be final and binding on the Company and on Optionee. 
  
 14.    Governing Law;
Severability.  This Agreement shall be governed by and construed in accordance with the laws of the State of North Carolina excluding that body of law pertaining to conflicts of law. Should any provision of this Agreement be determined
by a court of law to be illegal or unenforceable, the other provisions shall nevertheless remain effective and shall remain enforceable. 
  
 15.    Notices.  Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively

SALIX PHARMACEUTICALS, LTD. 
 2005
Stock Option Plan 
  
 EXERCISE NOTICE 
  
 Salix Pharmaceuticals, Ltd. 
 1700 Perimeter Park Drive, Suite 100 
 Morrisville, North Carolina 27560 
 Attention: Chief Financial Officer 
  
 1.    Exercise of Option.  Effective as
of today,                     , 20    , the undersigned (“Optionee”) hereby elects to exercise Optionee’s
option to purchase shares of the Common Stock (the “Shares”) of Salix Pharmaceuticals, Ltd. (the “Company”) under and pursuant to the Company’s 2005 Stock Plan, as amended (the “Plan”)
and the [            ] Incentive [            ] Nonstatutory Stock Option Agreement dated
                     (the “Option Agreement”). 
  
 2.    Representations of Optionees.  Optionee acknowledges that Optionee has received,
read and understood the Plan and the Option Agreement and agrees to abide by and be bound by their terms and conditions. Optionee represents that Optionee is purchasing the Shares for Optionee’s own account for investment and not with a view
to, or for sale in connection with, a distribution of any of such Shares. 
  
 3.    Compliance with Securities Laws.  Optionee understands and acknowledges that the Shares may not have been registered under the Securities Act of 1933, as amended (the
“1933 Act”), and, notwithstanding any other provision of the Option Agreement to the contrary, the exercise of any rights to purchase any Shares is expressly conditioned upon compliance with the 1933 Act, all applicable state
securities laws and all applicable requirements of any stock exchange or over the counter market on which the Company’s Common Stock may be listed or traded at the time of exercise and transfer. Optionee agrees to cooperate with the Company to
ensure compliance with such laws. 
  
 4.    Federal Restrictions on Transfer.  Optionee understands that if the Shares have not been registered under the 1933 Act, they cannot be resold and must be held indefinitely unless they are
registered under the 1933 Act or unless an exemption from such registration is available and that the certificate(s) representing the Shares may bear a legend to that effect. Optionee understands that the Company is under no obligation to register
the Shares and that an exemption may not be available or may not permit Optionee to transfer Shares in the amounts or at the times proposed by Optionee. Specifically, Optionee has been advised that Rule 144 promulgated under the 1933 Act, which
permits certain resales of unregistered securities, is not presently available with respect to the Shares and, in any event requires that the Shares be paid for and then be held for at a specified period before they may be resold under Rule 144.

  
 5.    Rights as
Stockholder.  Until the stock certificate evidencing such Shares is 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 shall exist with respect to the optioned Shares, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate 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 stock certificate is issued, except as provided in the Plan. 
  
 6.    Tax Consultation.  Optionee understands that Optionee may suffer adverse tax
consequences as a result of Optionee’s purchase or disposition of the Shares. Optionee represents that Optionee has consulted with any tax consultants Optionee deems advisable in connection with the purchase or disposition of the Shares and
that Optionee is not relying on the Company for any tax advice. 

 7.    Stop-Transfer Orders. 
  

	 	(a)	 	Stop-Transfer Notices.  Optionee agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop
transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records. 

  

	 	(b)	 	Refusal to Transfer.  The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of
the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred. 

  
 8.    Delivery of Payment.  Optionee
herewith delivers to the Company the full Exercise Price for the Shares. 
  
 9.    Entire Agreement.  The Plan and Notice of Grant/Option Agreement are incorporated herein by reference. This Agreement, the Plan and the Notice of Grant/Option Agreement
constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Optionee with respect to the subject matter hereof, and is governed by North Carolina law except for that body of
law pertaining to conflict of laws.
