(b)Powers of the Administrator.Subject to Applicable Laws and the provisions of the Plan (including any other
powers given to the Administrator hereunder), and except as otherwise provided by the Board, the Administrator shall have the authority, in its discretion:



5.Eligibility.Awards other than Incentive Stock Options may be granted to Employees, Directors and
Consultants. Incentive Stock Options may be granted only to Employees of the

5

---

Company, a Parent or a Subsidiary. An Employee, Director or Consultant who has been granted an Award may, if otherwise eligible, be granted additional Awards. Awards may be granted to such Employees,
Directors or Consultants who are residing in foreign jurisdictions as the Administrator may determine from time to time.

6.Terms and Conditions of Awards.

(a)Type of Awards.The Administrator is authorized under the Plan to award any type of arrangement to an
Employee, Director or Consultant that is not inconsistent with the provisions of the Plan and that by its terms involves or might involve the issuance of (i) Shares, (ii) an Option or
similar right with a fixed or variable price related to the Fair Market Value of the Shares and with an exercise or conversion privilege related to the passage of time, the occurrence of one or more
events, or the satisfaction of performance criteria or other conditions, or (iii) any other security with the value derived from the value of the Shares.

(b)Designation of Award.Each Award shall be designated in the Award Agreement. In the case of an Option, the
Option shall be designated as either an Incentive Stock Option or a Non-Qualified Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market
Value of Shares subject to Options designated as Incentive Stock Options which become exercisable for the first time by a Grantee during any calendar year (under all plans of the Company or any Parent
or Subsidiary) exceeds $100,000, such excess Options, to the extent of the Shares covered thereby in excess of the foregoing limitation, shall be treated as Non-Qualified Stock Options.
For this purpose, 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 date the Option
with respect to such Shares is granted.

(c)Conditions of Award.Subject to the terms of the Plan, the Administrator shall determine the provisions,
terms, and conditions of each Award including, but not limited to, the Award vesting schedule, repurchase provisions, rights of first refusal, forfeiture provisions, form of payment (cash,
Shares, or other consideration) upon settlement of the Award, payment contingencies, and satisfaction of any performance criteria. The performance criteria established by the Administrator may be
based on any one of, or combination of, increase in share price, earnings per share, total shareholder return, return on equity, return on assets, return on investment, net operating income, cash
flow, revenue, economic value added, personal management objectives, or other measure of performance selected by the Administrator. Partial achievement of the specified criteria may result in a
payment or vesting corresponding to the degree of achievement as specified in the Award Agreement.

(d)Acquisitions and Other Transactions.The Administrator may issue Awards under the Plan in settlement,
assumption or substitution for, outstanding awards or obligations to grant future awards in connection with the Company or a Related Entity acquiring another entity, an interest in another entity or
an additional interest in a Related Entity whether by merger, stock purchase, asset purchase or other form of transaction.

(e)Deferral of Award Payment.The Administrator may establish one or more programs under the Plan to permit
selected Grantees the opportunity to elect to defer receipt of consideration upon exercise of an Award, satisfaction of performance criteria, or other event that absent the election would entitle the
Grantee to payment or receipt of Shares or other consideration under an Award. The Administrator may establish the election procedures, the timing of such elections, the mechanisms for payments of,
and accrual of interest or other earnings, if any, on amounts, Shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable
for the administration of any such deferral program.

(f)Award Exchange Programs.The Administrator may establish one or more programs under the Plan to permit
selected Grantees to exchange an Award under the Plan for one or more other

6

---

types of Awards under the Plan on such terms and conditions as determined by the Administrator from time to time.

(g)Separate Programs.The Administrator may establish one or more separate programs under the Plan for the
purpose of issuing particular forms of Awards to one or more classes of Grantees on such terms and conditions as determined by the Administrator from time to time.

(h)Individual Option Limit.The maximum number of Shares with respect to which Options may be granted to any
Grantee in any fiscal year of the Company shall be Five Hundred Thousand (500,000). In connection with a Grantee's commencement of Continuous Service, a Grantee may be granted Options for up to an
additional Five Hundred Thousand (500,000) Shares which shall not count against the limit set forth in the previous sentence. The foregoing limitations shall be adjusted proportionately in connection
with any change in the Company's capitalization pursuant toSection 10, below. To the extent required by Section 162(m) of the Code or the
regulations thereunder, in applying the foregoing limitations with respect to a Grantee, if any Option is canceled, the canceled Option shall continue to count against the maximum number of Shares
with respect to which Options may be granted to the
Grantee. For this purpose, the repricing of an Option shall be treated as the cancellation of the existing Option and the grant of a new Option.

(i)Early Exercise.The Award Agreement may, but need not, include a provision whereby the Grantee may elect at
any time while an Employee, Director or Consultant to exercise any part or all of the Award prior to full vesting of the Award. Any unvested Shares received pursuant to such exercise may be subject to
a repurchase right in favor of the Company or a Related Entity or to any other restriction the Administrator determines to be appropriate.

(j)Term of Award.The term of each Award shall be the term stated in the Award Agreement, provided, however, that the term
of an Award shall be no more than ten (10) years from the date of grant thereof. However, in the case of an
Incentive Stock Option granted to a Grantee 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 Incentive Stock Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Award Agreement.

(k)Transferability of Awards.Incentive Stock Options 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 Grantee, only by the Grantee; provided, however,that the Grantee may designate a beneficiary of the Grantee's Incentive Stock Option in the event of the Grantee's death on a
beneficiary designation form provided by the Administrator. Other Awards may be transferred by gift or through a domestic relations order to members of the Grantee's Immediate Family to the extent
provided in the Award Agreement or in the manner and to the extent determined by the Administrator.

(l)Time of Granting Awards.The date of grant of an Award shall for all purposes be the date on which the
Administrator makes the determination to grant such Award, or such other date as is determined by the Administrator. Notice of the grant determination shall be given to each Employee, Director or
Consultant to whom an Award is so granted within a reasonable time after the date of such grant.

exercise or purchase of an Award 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). In
addition to any other types of consideration the Administrator may determine, the Administrator is authorized to accept as consideration for Shares issued under the Plan the following:

(c)Taxes.No Shares shall be delivered under the Plan to any Grantee or other person until such Grantee or
other person has made arrangements acceptable to the Administrator for the satisfaction of any foreign, federal, state, or local income and employment tax withholding obligations, including, without
limitation, obligations incident to the receipt of Shares or the disqualifying disposition of Shares received on exercise of an Incentive Stock Option. Upon exercise of an Award, the Company shall
withhold or collect from Grantee an amount sufficient to satisfy such tax obligations.

(b)Exercise of Award Following Termination of Continuous Service.

a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any such exercise that the

Laws.

Company, the number of Shares covered by each outstanding Award, and the number of Shares which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or
which have been returned to the Plan, the exercise or purchase price of each such outstanding Award, the maximum number of Shares with respect to which Options and may be granted to any Grantee in any
fiscal year of the Company, as well as any other terms that the Administrator determines require adjustment shall be proportionately adjusted for (i) any increase or decrease in the number of
issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Shares, or similar event affecting the Shares, (ii) any other increase or
decrease in the number of issued Shares effected without receipt of consideration by the Company, or (iii) as the Administrator may determine in its discretion, any other transaction with
respect to Common Stock to which Section 424(a) of the Code applies or any similar transaction;provided, howeverthat 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 and its determination shall be
final, binding and conclusive. Except as the Administrator determines, 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 hereof shall be made with respect to, the number or price of Shares subject to an Award.

the Grantee and the Administrator, which agreement must be in writing and signed by the Grantee and the Company.

14.Reservation of Shares.

(a)  The
Company, during the term of the Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the
Plan.

(b)  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

been obtained.

15.No Effect on Terms of Employment/Consulting Relationship.The Plan shall not confer upon any Grantee any
right with respect to the Grantee's Continuous Service, nor shall it interfere in any way with his or her right or the Company's right to terminate the Grantee's Continuous Service at any time, with
or without cause.

16.No Effect on Retirement and Other Benefit Plans.Except as specifically provided in a retirement or other

Entity, and shall not affect any benefits under any other benefit plan of any kind or any benefit plan subsequently instituted under which the availability or amount of benefits is related to level of
compensation. The Plan is not a "Retirement Plan" or "Welfare Plan" under the Employee Retirement Income Security Act of 1974, as amended.
