6.    OPTION PROVISIONS.

(a)Each Option shall be in such form and shall contain such terms and conditions as the Board shall deem appropriate. All
Options shall be separately designated Incentive Stock Options or Nonstatutory Stock Options at the time of grant, and, if certificates are issued, a separate certificate or certificates will be
issued for shares of Common Stock purchased on exercise of each type of Option. 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:

(b)Term.Subject to the provisions of subsection 5(b) regarding Ten Percent
Stockholders, no Incentive Stock Option shall be exercisable after the expiration of ten (10) years from the date it was granted.

(c)Exercise Price of an Incentive Stock Option.Subject to the provisions of
subsection 5(b) regarding Ten Percent Stockholders, the exercise price of each Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock
subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Incentive 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.

(d)Exercise Price of a Nonstatutory Stock Option.The exercise price of each
Nonstatutory Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the
foregoing, 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.

(e)Consideration.The purchase price of Common 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 at the
time of the grant of the Option (or subsequently in the case of a Nonstatutory Stock Option) (1) by delivery to the Company of other Common Stock, (2) according to a deferred payment or
other similar arrangement with the Optionholder or (3) in any other form of legal consideration that may be acceptable to the Board. Unless otherwise specifically provided in the Option, the
purchase price of Common Stock acquired

5

---

pursuant to an Option that is paid by delivery to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company
that have been held for more than six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). At any time that the
Company is incorporated in Delaware, payment of the Common Stock's "par value," as defined in the Delaware General Corporation Law, shall not be made by deferred payment.

(f)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.

(g)Transferability of an Incentive Stock Option.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 Optionholder only by the Optionholder. Notwithstanding the
foregoing, the Optionholder 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 Optionholder, shall
thereafter be entitled to exercise the Option.

(h)Transferability of a Nonstatutory Stock Option.A Nonstatutory Stock
Option shall be transferable to the extent provided in the Option Agreement. If the Nonstatutory Stock Option does not provide for transferability, then the Nonstatutory 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 Optionholder only by the Optionholder. Notwithstanding the foregoing, the
Optionholder 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 Optionholder, shall thereafter be
entitled to exercise the Option.

(i)Vesting Generally.The total number of shares of Common Stock subject to
an Option may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. 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 vesting provisions of individual Options may vary. The provisions of this
subsection 6(i) are subject to any Option provisions governing the minimum number of shares of Common Stock as to which an Option may be exercised.

(j)Termination of Continuous Service.In the event an Optionholder's
Continuous Service terminates (other than upon the Optionholder's death or Disability), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise
such Option 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 Optionholder's
Continuous Service (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 Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate.

(k)Extension of Termination Date.An Optionholder's Option Agreement may
also provide that if the exercise of the Option following the termination of the Optionholder's Continuous Service (other than upon the Optionholder's death or Disability) would be prohibited at any
time solely because the issuance of shares of Common Stock 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 subsection 6(b) or (ii) the expiration of a period of three (3) months after the termination of the Optionholder's Continuous Service
during which the exercise of the Option would not be in violation of such registration requirements.

6

---

(l)Disability of Optionholder.In the event that an Optionholder's
Continuous Service terminates as a result of the Optionholder's Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option 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, after termination, the Optionholder does not exercise his or her
Option within the time specified herein, the Option shall terminate.

(m)Death of Optionholder.In the event (i) an Optionholder's
Continuous Service terminates as a result of the Optionholder's death or (ii) the Optionholder dies within the period (if any) specified in the Option Agreement after the termination of the
Optionholder's Continuous Service for a reason other than death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the
Optionholder'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 Optionholder's death pursuant to
subsection 6(g) or 6(h), but only within the period ending on the earlier of (1) the date eighteen (18) months following the date of death (or such longer or shorter period specified in
the Option Agreement) or (2) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the
Option shall terminate.

(n)Early Exercise.The Option may, but need not, include a provision whereby
the Optionholder may elect at any time before the Optionholder's Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to
the full vesting of the Option. Any unvested shares of Common Stock so purchased may be subject to a repurchase option in favor of the Company or to any other restriction the Board determines to be
appropriate. The Company will not exercise its repurchase option until at least six (6) months (or such longer or shorter period of time required to avoid a charge to earnings for financial
accounting purposes) have elapsed following exercise of the Option unless the Board otherwise specifically provides in the Option.

7.    COVENANTS OF THE COMPANY.

(a)Availability of Shares.During the terms of the Stock Awards, the Company
shall keep available at all times the number of shares of Common Stock required to satisfy such Stock Awards.

(b)Securities Law Compliance.The Company shall seek to obtain from each
regulatory commission or agency having jurisdiction over the Plan such authority as may be required to grant Stock Awards and to issue and sell shares of Common Stock upon exercise of the Stock
Awards; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Stock Award or any Common 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 Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Stock Awards unless and until such
authority is obtained.

8.    USE OF PROCEEDS FROM STOCK.

Proceeds from the sale of Common Stock pursuant to Stock Awards shall constitute general funds of the Company.

9.    MISCELLANEOUS.

(a)Acceleration of Exercisability and Vesting.The Board shall have the
power to accelerate the time at which a Stock Award may first vest and/or be exercised in accordance with the Plan,

7

---

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)Stockholder Rights.No Participant shall be deemed to be the holder of,
or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Stock Award unless and until such Participant has satisfied all requirements for exercise of the
Stock Award pursuant to its terms.

(c)No Employment or Other Service Rights.Nothing in the Plan or any
instrument executed or Stock Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Stock
Award was granted or shall affect the right of the Company or an Affiliate to terminate (i) the employment of an Employee with or without notice and with or without cause, (ii) the
service of a Consultant pursuant to the terms of such Consultant's agreement with the Company or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the Company or an
Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be.

(d)Incentive Stock Option $100,000 Limitation.To the extent that the
aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder 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 limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options.

(e)Investment Assurances.The Company may require a Participant, as a
condition of exercising or acquiring Common Stock under any Stock Award, (i) to give written assurances satisfactory to the Company as to the Participant'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 (ii) to give written assurances satisfactory to the Company stating that the Participant is
acquiring Common Stock subject to the Stock Award for the Participant's own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing
requirements, and any assurances given pursuant to such requirements, shall be inoperative if (1) the issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock
under the Stock Award has been registered under a then currently effective registration statement under the Securities Act or (2) 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 Common Stock.

(f)Withholding Obligations.To the extent provided by the terms of a Stock
Award Agreement, the Participant may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of Common Stock under a Stock Award by any of the following
means (in addition to the Company's right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (i) tendering a cash payment;
(ii) authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant as a result of the exercise or acquisition of Common Stock
under the Stock Award, provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law; or (iii) delivering to the
Company owned and unencumbered shares of Common Stock.

10.  ADJUSTMENTS UPON CHANGES IN STOCK.

(a)Capitalization Adjustments. If any change is made in the Common Stock
subject to the Plan, or subject to any Stock Award, without the receipt of consideration by the Company (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 class(es) 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 pursuant to subsection 5(c), and the outstanding Stock Awards will be appropriately adjusted in the class(es) and number of securities and price per
share of Common Stock subject to such outstanding Stock Awards. The Board shall make such adjustments, and its determination shall be final, binding and conclusive. The conversion of any convertible
securities of the Company shall not be treated as a transaction "without receipt of consideration" by the Company.

(b)Dissolution or Liquidation. In the event of a dissolution or liquidation
of the Company, then all outstanding Stock Awards shall terminate immediately prior to such event.

(c)Change of Control.



(d)For purposes of this Plan, "Change of Control" means: (i) a sale of substantially all of the assets of the
Company; (ii) a merger or consolidation in which the Company is not the surviving corporation (other than a merger or consolidation in which shareholders immediately before the merger or
consolidation have, immediately after the merger or consolidation, equal or greater stock voting power); (iii) a reverse merger in which the Company is the surviving corporation but the shares
of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise (other than a reverse
merger in which stockholders immediately before the merger have, immediately after the merger, greater stock voting power); or (iv) any transaction or series of related transactions in which in
excess of 50% of the Company's voting power is transferred.

11.  AMENDMENT OF THE PLAN AND STOCK AWARDS.

(b)Stockholder Approval.The Board may, in its sole discretion, submit any

(c)Contemplated Amendments.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.

amendment of the Plan shall not be impaired by any amendment of the Plan unless (i) the Company requests the consent of the Participant and (ii) the Participant consents in writing.

(e)Amendment of Stock Awards.The Board at any time, and from time to time,
may amend the terms of any one or more Stock Awards; provided, however, that the rights under any Stock Award shall not be impaired by any such amendment unless (i) the Company requests the
consent of the Participant and (ii) the Participant consents in writing. Notwithstanding the foregoing, the Board shall not, without the approval of the stockholders of the Company, authorize
the amendment of any outstanding Option to reduce its exercise price. Furthermore, no Option shall be canceled and replaced with grants having a lower exercise price without the further approval of
stockholders of the Company.

12.  TERMINATION OR SUSPENSION OF THE PLAN.

(a)Plan Term.The Board may suspend or terminate the Plan at any time.
Unless sooner terminated, the Plan shall terminate on the day before the tenth (10th) anniversary of the date the Plan is initially adopted by the Board or approved by the stockholders of the Company,
whichever is earlier. No Stock Awards may be granted under the Plan while the Plan is suspended or after it is terminated.

(b)No Impairment of Rights.Suspension or termination of the Plan shall not
impair rights and obligations under any Stock Award granted while the Plan is in effect except with the written consent of the Participant.

13.  EFFECTIVE DATE OF PLAN.

The Plan shall become effective upon its adoption by the Board, but no Stock Award 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.

14.  CHOICE OF LAW.

conflict of laws rules.
