 (a)
The Plan shall be administered by the Board unless and until the Board delegates administration to a Committee, as provided in subsection 3(c). 
  

 4 









 (b) The Board shall have the power, subject to, and within the limitations of, the express
provisions of the Plan: 
  
 (i) To
determine from time to time which of the persons eligible under the Plan shall be granted Stock Awards; when and how each Stock Award shall be granted; whether a Stock Award will be a Nonstatutory Stock Option, a stock bonus, a right to purchase
restricted stock, or a combination of the foregoing; the provisions of each Stock Award granted (which need not be identical), including the time or times when a person shall be permitted to receive stock pursuant to a Stock Award; and the number of
shares with respect to which a Stock Award shall be granted to each such person. 
  
 (ii) To construe and interpret the Plan and Stock Awards granted under it, and to establish, amend and revoke rules and regulations
for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan or in any Stock Award Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan
fully effective. 
  
 (iii) To amend the
Plan or a Stock Award as provided in Section 13.

Committee at any time and revest in the Board the administration of the Plan. 
  
 4. SHARES SUBJECT TO THE PLAN. 
  
 (a) Subject to the provisions of Section 13 relating to adjustments upon changes in stock, the number of shares of stock that may be issued
pursuant to Stock Awards shall not exceed in the aggregate one million one thousand two hundred (1,001,200) shares of the Company’s common stock. If any Stock Award shall for any reason expire or otherwise terminate, in whole or in part,
without having been exercised in full, the stock not acquired under such Stock Award shall revert to and again become available for issuance under the Plan. 
  
 (b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 
  
 5. ELIGIBILITY. 
  
 Stock Awards may be granted only to Employees or Consultants. Provided
further, that Covered Employees shall not be eligible to receive Stock Awards under the Plan, and Officers 

  

 5 









 
other than Covered Employees are only eligible to receive grants that are an inducement essential to such individual entering into an employment agreement
with the Company or an Affiliate of the Company. 
  
 6. OPTION
PROVISIONS. 
  
 Each Option shall be in such
form and shall contain such terms and conditions as the Board shall deem appropriate. The provisions of separate Options need not be identical, but each Option shall include (through incorporation of provisions hereof by reference in the Option or
otherwise) the substance of each of the following provisions: 
  
 (a) Term. No Option shall be exercisable after the expiration of ten (10) years from the date it was granted. 
  
 (b) Price. The exercise price of each Nonstatutory Stock Option shall be not less than eighty-five percent (85%) of the Fair Market Value of
the stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be granted with an exercise price lower than that set forth in the
preceding sentence if such Option is granted pursuant to an assumption of or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code. 
  
 (c) Consideration. The purchase price of stock acquired pursuant to an Option shall be paid, to the extent permitted
by applicable statutes and regulations, either (i) in cash at the time the Option is exercised, or (ii) at the discretion of the Board or the Committee, at the time of the grant of the Option, (A) by delivery to the Company of other
common stock of the Company, (B) according to a deferred payment arrangement, except that payment of the common stock’s “par value” (as defined in the Delaware General Corporation Law) shall not be made by deferred payment, or
other arrangement (which may include, without limiting the generality of the foregoing, the use of other common stock of the Company) with the person to whom the Option is granted or to whom the Option is transferred pursuant to subsection 6(d), or
(C) in any other form of legal consideration that may be acceptable to the Board. 
  
 In the case of any deferred payment arrangement, interest shall be compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest under the deferred payment arrangement. 
  
 (d) Transferability. An Option shall not be transferable except by will or by the laws of descent and distribution, and shall be exercisable during
the lifetime of the person to whom the Option is granted only by such person unless the applicable Option Agreement expressly provides for other transferability. Notwithstanding the foregoing, the person to whom the Option is granted may, by
delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionee, shall thereafter be entitled to exercise the Option. 
  

 6 









 (e) Vesting. The total number of shares of stock subject to an Option may, but need not, be
allotted in periodic installments (which may, but need not, be equal). The Option Agreement may provide that from time to time during each of such installment periods, the Option may become exercisable (“vest”) with respect to some or all
of the shares allotted to that period, and may be exercised with respect to some or all of the shares allotted to such period and/or any prior period as to which the Option became vested but was not fully exercised. The Option may be subject to such
other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate. The provisions of this subsection 6(e) are subject to any Option provisions governing
the minimum number of shares as to which an Option may be exercised. 
  
 (f) Termination of Employment or Consulting Relationship. In the event an Optionee’s Continuous Service as an Employee, Director or Consultant terminates (other than upon the Optionee’s death or disability), the Optionee
may exercise his or her Option (to the extent that the Optionee was entitled to exercise it as of the date of termination, unless the Option Agreement expressly provides that the Option may become exercisable for additional shares after the date of
termination) but only within such period of time ending on the earlier of (i) the date three (3) months following the termination of the Optionee’s Continuous Service as an Employee, Director or Consultant (or such longer or shorter
period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. If, at the date of termination, the Optionee is not entitled to exercise his or her entire Option, the shares
covered by the unexercisable portion of the Option shall revert to and again become available for issuance under the Plan. If, after termination, the Optionee does not exercise his or her Option within the time specified in the Option Agreement, the
Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance under the Plan. 
  
 An Optionee’s Option Agreement may also provide that if the exercise of the Option following the termination of the Optionee’s Continuous
Service as an Employee, Director or Consultant (other than upon the Optionee’s death or disability) would result in liability under Section 16(b) of the Exchange Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in the Option Agreement, or (ii) the tenth (10th) day after the last date on which such exercise would result in such liability under Section 16(b) of the Exchange Act. Finally, an
Optionee’s Option Agreement may also provide that if the exercise of the Option following the termination of the Optionee’s Continuous Service as an Employee, Director or Consultant (other than upon the Optionee’s death or disability)
would be prohibited at any time solely because the issuance of shares would violate the registration requirements under the Securities Act, then the Option shall terminate on the earlier of (i) the expiration of the term of the Option set forth
in the first paragraph of this subsection 6(f), or (ii) the expiration of a period of three (3) months after the termination of the Optionee’s Continuous Service as an Employee, Director or Consultant during which the exercise of the
Option would not be in violation of such registration requirements. 
  
 (g) Disability of Optionee. In the event an Optionee’s Continuous Service as an Employee, Director or Consultant terminates as a result of the Optionee’s disability, the Optionee may exercise his or her Option (to the
extent that the Optionee was entitled to exercise it as of the date of termination, unless the Option Agreement expressly provides that the Option may become 

  

 7 









 
exercisable for additional shares after the date of termination), but only within such period of time ending on the earlier of (i) the date twelve
(12) months following such termination (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the term of the Option as set forth in the Option Agreement. 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 and again become available for issuance under the Plan. 
  
 (h) Death of Optionee. In the event of the death of an Optionee
during, or within a period specified in the Option Agreement after the termination of, the Optionee’s Continuous Service as an Employee, Director or Consultant, the Option may be exercised (to the extent the Optionee was entitled to exercise
the Option as of the date of death) by the Optionee’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the option upon the Optionee’s death pursuant to
subsection 6(d), but only within the period ending on the earlier of (i) the date eighteen (18) months following the date of death (or such longer or shorter period specified in the Option Agreement), or (ii) the expiration of the
term of such Option as set forth in the Option Agreement. If, at the time of death, the Optionee was not entitled to exercise his or her entire Option, the shares covered by the unexercisable portion of the Option shall revert to and again become
available for issuance under the Plan. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate, and the shares covered by such Option shall revert to and again become available for issuance under the
Plan. 
  
 (i) Early Exercise. The Option may, but need not,
include a provision whereby the Optionee may elect at any time during Continuous Service as an Employee, Director or Consultant to exercise the Option as to any part or all of the shares subject to the Option prior to the full vesting of the Option.
Any unvested shares so purchased may be subject to a repurchase right in favor of the Company or to any other restriction the Board determines to be appropriate. 
  
 7. TERMS OF STOCK BONUSES AND PURCHASES
OF RESTRICTED STOCK. 
  
 Each stock bonus or restricted stock purchase agreement shall be in such form and shall contain such terms and conditions as the Board or the Committee shall deem appropriate. The terms and conditions of stock bonus or restricted stock
purchase agreements may change from time to time, and the terms and conditions of separate agreements need not be identical, but each stock bonus or restricted stock purchase agreement shall include (through incorporation of provisions hereof by
reference in the agreement or otherwise) the substance of each of the following provisions as appropriate: 
  
 (a) Purchase Price. The purchase price under each restricted stock purchase agreement shall be such amount as the Board or Committee shall
determine and designate in such Stock Award Agreement. Notwithstanding the foregoing, the Board or the Committee may determine that eligible participants in the Plan may be awarded stock pursuant to a stock bonus agreement in consideration for past
services actually rendered to the Company or for its benefit. 
  
 (b) Transferability. Rights under a stock bonus or restricted stock purchase agreement shall be transferable by the grantee only upon such terms and conditions as are set 

  

 8 









 
forth in the applicable Stock Award Agreement, as the Board or the Committee shall determine in its discretion, so long as stock awarded under such Stock
Award Agreement remains subject to the terms of the agreement. 
  
 (c) Consideration. The purchase price of stock acquired pursuant to a stock purchase agreement shall be paid either: (i) in cash at the time of purchase; (ii) at the discretion of the Board or the Committee, according to a
deferred payment or other arrangement, except that payment of the common stock’s “par value” (as defined in the Delaware General Corporation Law) shall not be made by deferred payment, or other arrangement with the person to whom the
stock is sold; or (iii) in any other form of legal consideration that may be acceptable to the Board or the Committee in its discretion. Notwithstanding the foregoing, the Board or the Committee to which administration of the Plan has been
delegated may award stock pursuant to a stock bonus agreement in consideration for past services actually rendered to the Company or for its benefit. 
  
 (d) Vesting. Shares of stock sold or awarded under the Plan may, but need not, be subject to a repurchase option in favor of the Company in
accordance with a vesting schedule to be determined by the Board or the Committee. 
  
 (e) Termination of Continuous Service as an Employee, Director or Consultant. In the event a participant’s Continuous Service as an Employee, Director or Consultant terminates, the Company may repurchase
or otherwise reacquire any or all of the shares of stock held by that person which have not vested as of the date of termination under the terms of the stock bonus or restricted stock purchase agreement between the Company and such person.

  
 8. Cancellation And Re-Grant Of Options. The Board or the Committee
shall have the authority to effect, at any time and from time to time, (i) the repricing of any outstanding Options under the Plan and/or (ii) with the consent of the affected holders of Options, the cancellation of any outstanding Options
under the Plan and the grant in substitution therefor of new Options under the Plan covering the same or different numbers of shares of stock, but having an exercise price per share per share of stock on the new grant date that results in a ratio
between such exercise price and Fair Market Value on such date of grant that is not less than the ratio between the original exercise price and Fair Market Value on the original date of grant. Notwithstanding the foregoing, the Board or the
Committee may grant an Option with an exercise price lower than that set forth above if such Option is granted as part of a transaction described in section 424(a) of the Code. 
  
 9. COVENANTS OF THE COMPANY. 
  
 (a) During the terms of the Stock Awards, the Company shall keep
available at all times the number of shares of stock required to satisfy such Stock Awards. 
  
 (b) The Company shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to issue and sell shares of stock upon exercise of the Stock
Award; provided, however, that this undertaking shall not require the Company to register under the Securities Act, either the Plan, any Stock Award or any stock issued or issuable pursuant to any such Stock Award. If, after reasonable
efforts, the 

  

 9 









 
Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance
and sale of stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell stock upon exercise of such Stock Awards unless and until such authority is obtained. 
  
 10. USE OF PROCEEDS FROM
STOCK. 
  
 Proceeds from the sale of stock
pursuant to Stock Awards shall constitute general funds of the Company. 
  
 11.
MISCELLANEOUS. 
  
 (a) The Board shall
have the power to accelerate the time at which a Stock Award may first be exercised or the time during which a Stock Award or any part thereof will vest pursuant to subsection 6(e) or 7(d), notwithstanding the provisions in the Stock Award stating
the time at which it may first be exercised or the time during which it will vest. 
  
 (b) Neither an Employee or Consultant nor any person to whom a Stock Award is transferred under subsection 6(d) or 7(b) shall be deemed to be the holder of, or to have any of the rights of a holder with respect
to, any shares subject to such Stock Award unless and until such person has satisfied all requirements for exercise of the Stock Award pursuant to its terms. 
  
 (c) Nothing in the Plan or any instrument executed or Stock Award granted pursuant thereto shall confer upon any Employee, Consultant or other
holder of Stock Awards any right to continue in the employ of the Company or any Affiliate (or to continue acting as a Director or Consultant) or shall affect the right of the Company or any Affiliate to terminate the employment of any Employee with
or without cause to terminate the relationship of any Consultant in accordance with the terms of that Consultant’s agreement with the Company or Affiliate of the Company to which such Consultant is providing services. 
  
 (d) The Company may require any person to whom a Stock Award is
granted, or any person to whom a Stock Award is transferred pursuant to subsection 6(d) or 7(b), as a condition of exercising or acquiring stock under any Stock Award, (1) to give written assurances satisfactory to the Company as to such
person’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters, and that he or she is
capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Stock Award; and (2) to give written assurances satisfactory to the Company stating that such person is acquiring the stock
subject to the Stock Award for such person’s own account and not with any present intention of selling or otherwise distributing the stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative
if (i) the issuance of the shares upon the exercise or acquisition of stock under the Stock Award has been registered under a then currently effective registration statement under the Securities Act, or (ii) as to any particular
requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or 

  

 10 









 
appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the stock. 
  
 (e) To the extent provided by the terms of a Stock Award Agreement,
the person to whom a Stock Award is granted may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of stock under a Stock Award by any of the following means or by a combination of such means:
(1) tendering a cash payment; (2) authorizing the Company to withhold shares from the shares of the common stock otherwise issuable to the participant as a result of the exercise or acquisition of stock under the Stock Award; or
(3) delivering to the Company owned and unencumbered shares of the common stock of the Company. 
  
 12. ADJUSTMENTS UPON CHANGES IN STOCK. 
  
 (a) If any change is made in the stock subject to the Plan, or subject to any Stock Award (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan will be appropriately adjusted in the type(s) and maximum number of securities subject to the Plan pursuant to subsection 4(a), and the outstanding Stock Awards will be appropriately adjusted in the type(s)
and number of securities and price per share of stock subject to such outstanding Stock Awards. Such adjustments shall be made by the Board or the Committee, the determination of which shall be final, binding and conclusive. (The conversion of any
convertible securities of the Company shall not be treated as a “transaction not involving the receipt of consideration by the Company”.) 
  
 (b) In the event of a Change of Control, then: (i) any surviving corporation or acquiring corporation shall assume any Stock Awards
outstanding under the Plan or shall substitute similar stock awards (including an award to acquire the same consideration paid to the stockholders in the transaction described in this subsection 12(b)) for those outstanding under the Plan, or
(ii) in the event any surviving corporation or acquiring corporation refuses to assume such Stock Awards or to substitute similar stock awards for those outstanding under the Plan, (A) with respect to Stock Awards held by persons then
performing services as Employees, Directors or Consultants the vesting of such Stock Awards (and, if applicable, the time during which such Stock Awards may be exercised) shall be accelerated prior to such event and the Stock Awards terminated if
not exercised (if applicable) after such acceleration and at or prior to such event, and (B) with respect to any other Stock Awards outstanding under the Plan, such Stock Awards shall be terminated if not exercised (if applicable) prior to such
event. If any acquiring or surviving corporation assumes Stock Awards outstanding under the Plan or substitutes similar stock awards for those outstanding under the Plan, then if the Continuous Service as an Employee, Director or Consultant of the
holder of a Stock Award (or substitute stock award) is terminated for any reason other than (i) death, (ii) Cause, (iii) illness, accident, or other physical or mental incapacity which prevents the holder of such award from performing
his or her duties for more than one hundred and eighty (180) days during any twelve (12) month 

  

 11 









 
period, or (iv) Voluntary Resignation, then the vesting of such award shall be accelerated in full and, if applicable, such award shall be exercisable
