thousand seven hundred sixty eight (248,768) shares of the Company’s common stock which is currently subject to outstanding awards under the Company’s 1994 Non-Employee Directors’ Stock Option Plan that may subsequently cease to
be subject to such awards (as a result of cancellations or expirations of options) and will then become available under the Plan. 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. 
  

 6 









 (b) The stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or
otherwise. 
  

	5.	ELIGIBILITY. 

  
 (a) Incentive Stock Options may be granted only to Employees. Stock Awards other than Incentive Stock Options may be granted only to Employees, Directors
or Consultants. 
  
 (b) No person shall be eligible for the grant
of an Incentive Stock Option if, at the time of grant, such person owns (or is deemed to own pursuant to Section 424(d) of the Code) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of
the Company or of any of its Affiliates unless the exercise price of such Incentive Stock Option is at least one hundred ten percent (110%) of the Fair Market Value of such stock at the date of grant and the Incentive Stock Option is not
exercisable after the expiration of five (5) years from the date of grant. 
  
 (c) Subject to the provisions of Section 12 relating to adjustments upon changes in stock, no person shall be eligible to be granted Options covering more than two hundred fifty thousand (250,000) shares of
the Company’s common stock in any calendar year. 
  

	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 Incentive Stock
Option shall be not less than one hundred percent (100%) of the Fair Market Value of the stock subject to the Option on the date the Option is granted; the exercise price of each Nonstatutory Stock Option shall be determined 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 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 

  

 7 









 
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 Incentive Stock 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 Incentive Stock Option is granted only by
such person. A Nonstatutory Stock Option shall only be transferable by the Optionee upon such terms and conditions as are set forth in the Option Agreement for such Nonstatutory Stock Option, as the Board or the Committee shall determine in its
discretion. 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. 
  
 (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 Relationship as a Director or Consultant. 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) 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 Status
as an Employee, Director, or Consultant (other than upon the Optionee’s death or disability) would result in liability under 

  

 8 









 
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), 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, 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 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 while 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. 
  

 9 









 (j) Re-Load Options. Without in any way limiting the authority of the Board or Committee to make
or not to make grants of Options hereunder, the Board or Committee shall have the authority (but not an obligation) to include as part of any Option Agreement a provision entitling the Optionee to a further Option (a “Re-Load Option”) in
the event the Optionee exercises the Option evidenced by the Option agreement, in whole or in part, by surrendering other shares of Common Stock in accordance with this Plan and the terms and conditions of the Option Agreement. Any such Re-Load
Option (i) shall be for a number of shares equal to the number of shares surrendered as part or all of the exercise price of such Option; (ii) shall have an expiration date which is the same as the expiration date of the Option the
exercise of which gave rise to such Re-Load Option; and (iii) shall have an exercise price which is equal to one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Re-Load Option on the date of exercise of
the original Option. Notwithstanding the foregoing, a Re-Load Option which is an Incentive Stock Option and which is granted to a 10% stockholder (as described in subsection 5(b)), shall have an exercise price which is equal to one hundred ten
percent (110%) of the Fair Market Value of the stock subject to the Re-Load Option on the date of exercise of the original Option and shall have a term which is no longer than five (5) years. 
  
 Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
Stock Option, as the Board or Committee may designate at the time of the grant of the original Option; provided, however, that the designation of any Re-Load Option as an Incentive Stock Option shall be subject to the one hundred thousand
dollar ($100,000) annual limitation on exercisability of Incentive Stock Options described in subsection 11(e) of the Plan and in Section 422(d) of the Code. There shall be no Re-Load Options on a Re-Load Option. Any such Re-Load Option shall
be subject to the availability of sufficient shares under subsection 4(a) and the limits on the grants of Options under subsection 5(c) and shall be subject to such other terms and conditions as the Board or Committee may determine which are not
inconsistent with the express provisions of the Plan regarding the terms of Options. 
  

	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 

  

 10 









 
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 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 Employment or Relationship as a 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. 

  
 (a) The Board or the Committee shall have the authority to effect, at any
time and from time to time, 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 not less than the ratio between the original exercise price and Fair Market Value on the original date of grant (one hundred percent (100%) of the Fair Market Value in the case of an
Incentive Stock Option) or, in the case of a 10% stockholder (as described in subsection 5(b)) receiving a new grant of an Incentive Stock Option, not less than one hundred ten percent (110%) of the Fair Market Value) per share of stock on the
new grant date. 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 to which section 424(a) of the Code applies.

  
 (b) Shares subject to an Option canceled under this
Section 8 shall continue to be counted against the maximum award of Options permitted to be granted pursuant to subsection 5(c) of the Plan. The provisions of this subsection 8(b) shall be applicable only to the extent required by
Section 162(m) of the Code. 
  

 11 










	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 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. 

  
 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), 7(d) or 8(b), 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. 
  
 (a) Neither an Employee, Director or Consultant nor any person to whom a
Stock Award is transferred under subsection 6(d), 7(b), or 8(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. 
  
 (b) Nothing in the Plan or any instrument executed or Stock Award granted pursuant thereto shall confer upon any Employee, Director, 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 the right of the Company’s Board of Directors and/or the
Company’s stockholders to remove any Director as provided in the Company’s Bylaws and the provisions of the Delaware General Corporation Law, or the right to terminate the relationship of any Consultant subject to the terms of such
Consultant’s agreement with the Company or Affiliate. 
  
 (c)
To the extent that the aggregate Fair Market Value (determined at the time of grant) of stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year under all plans of the Company
and its Affiliates exceeds one hundred thousand dollars ($100,000), the Options or portions thereof which exceed such 

  

 12 









 
limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options. 
  
 (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), 7(b) or 8(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 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
maximum number of securities subject to award to any person during any calendar year pursuant to subsection 5(c), 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”.) 
  

 13 









 (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 period, or (iv) Voluntary Resignation, then the vesting of such award shall be accelerated in full
and, if applicable, such award shall be exercisable in full for the post-termination exercise period provided in such award’s agreement. 
  

	13.	AMENDMENT OF THE PLAN AND STOCK AWARDS.


  
 (a) The Board at any time, and from time to
time, may amend the Plan. However, except as provided in Section 12 relating to adjustments upon changes in stock, no amendment shall be effective unless approved by the stockholders of the Company within twelve (12) months before or after
the adoption of the amendment, where the amendment will: 
  
 (i) Increase the number of shares reserved for Stock Awards under the Plan; 
  
 (ii) Modify the requirements as to eligibility for participation in the Plan (to the extent such modification requires stockholder
approval in order for the Plan to satisfy the requirements of Section 422 of the Code); or 
  
 (iii) Modify the Plan in any other way if such modification requires stockholder approval in order for the Plan to satisfy the
requirements of Section 422 of the Code or to comply with exchange listing requirements. 
  
 (b) The Board may in its sole discretion submit any other amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of
Section 162(m) of the Code and the regulations promulgated thereunder regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to certain executive officers. 
  

 14 









 (c) It is expressly contemplated that the Board may amend the Plan in any respect the Board deems
necessary or advisable to provide eligible Employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options and/or to bring the Plan and/or
Incentive Stock Options granted under it into compliance therewith. 
  
 (d) Rights and obligations under any Stock Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the person to whom the Stock Award was granted and
(ii) such person consents in writing. 
  
 (e) The Board at
any time, and from time to time, may amend the terms of any one or more Stock Award; provided, however, that the rights and obligations under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the
consent of the person to whom the Stock Award was granted and (ii) such person consents in writing. 
  

	14.	TERMINATION OR SUSPENSION OF THE PLAN. 

  
 (a) The Board may suspend or terminate the Plan at any time. Unless sooner
terminated, the Plan shall terminate on the day prior to the tenth anniversary of the earlier of the date the Plan is adopted by the Board or the date the Plan is approved by the stockholders of the Company. No Stock Awards may be granted under the
Plan while the Plan is suspended or after it is terminated. 
  
 (b) Rights and obligations under any Stock Award granted while the Plan is in effect shall not be impaired by suspension or termination of the Plan, except with the written consent of the person to whom the Stock Award was granted.

  

	15.	EFFECTIVE DATE OF PLAN. 

  
 The Plan shall become effective as determined by the Board, but no Stock
Awards granted under the Plan shall be exercised unless and until the Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board.
