      4.2 METHOD OF EXERCISE. Exercise of the Option shall be by means of
electronic or written notice (the "EXERCISE NOTICE") in a form authorized by the
Company. An electronic Exercise Notice must be digitally signed or authenticated
by the Participant in such manner as required by the notice and transmitted to
the Company or an authorized representative of the Company (including a
third-party administrator designated by the Company). In the event that the
Participant is not authorized or is unable to provide an electronic Exercise
Notice, the Option shall be exercised by a written Exercise Notice addressed to
the Company, which shall be signed by the Participant and delivered in person,
by certified or registered mail, return receipt requested, by confirmed
facsimile transmission, or by such other means as the Company may permit, to the
Company, or an authorized representative of the Company (including a third-party
administrator designated by the Company). Each Exercise Notice, whether
electronic or written, must state the Participant's election to exercise the
Option, the number of whole shares of Stock for which the Option is being
exercised and such other representations and agreements as to the Participant's
investment intent with respect to such shares as may be required pursuant to the
provisions of this Option Agreement. Further, each Exercise Notice must be
received by the Company prior to the termination of the Option as set forth in
Section 6 and must be accompanied by full payment of the aggregate Exercise
Price for the number of shares of Stock being purchased. The Option shall be
deemed to be exercised upon receipt by the Company of such electronic or written
Exercise Notice and the aggregate Exercise Price.

      4.3 PAYMENT OF EXERCISE PRICE.

            (A) FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise provided
below, payment of the aggregate Exercise Price for the number of shares of Stock
for which the Option is being exercised shall be made (i) in cash or by check or
cash equivalent, (ii) if permitted by the Company, by tender to the Company, or
attestation to the ownership, of whole shares of Stock owned by the Participant
having a Fair Market Value not less than the aggregate Exercise Price, (iii) by
means of a Cashless Exercise, as defined in Section 4.3(b), or (iv) by any
combination of the foregoing.

            (B) LIMITATIONS ON FORMS OF CONSIDERATION.

                  (I) TENDER OF STOCK. Notwithstanding the foregoing, the Option
may not be exercised by tender to the Company, or attestation to the ownership,
of shares of Stock to the extent such tender or attestation would constitute a
violation of the provisions of any law, regulation or agreement restricting the
redemption of the Company's stock. If required by the Company, the Option may
not be exercised by tender to the Company, or attestation to the ownership, of
shares of Stock unless such shares either have been owned by the Participant for
more than six (6) months or such other period, if any, required by the Company
(and not used for another option exercise by attestation during such period) or
were not acquired, directly or indirectly, from the Company.

                  (II) CASHLESS EXERCISE. A "CASHLESS EXERCISE" means the
delivery of a properly executed notice together with irrevocable instructions to
a broker in a form acceptable to the Company providing for the assignment to the
Company of the proceeds of a sale or loan with respect to some or all of the
shares of Stock acquired upon the exercise of the Option pursuant to a program
or procedure approved by the Company (including, without limitation, through an
exercise complying with the provisions of Regulation T as promulgated from time
to time by the Board of Governors of the Federal Reserve System). The Company
reserves, at any and all times, the right, in the Company's sole and absolute
discretion, to establish, decline to approve, or terminate any such program or
procedure, including with respect to the Participant notwithstanding that such
program or procedures may be available to others.

      4.4 TAX WITHHOLDING. At the time the Option is exercised, in whole or in
part, or at any time thereafter as requested by the Company, the Participant
hereby authorizes withholding from payroll and any other amounts payable to the
Participant, and otherwise agrees to make adequate provision for (including by
means of a Cashless Exercise to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Participating Company Group, if any, which arise in
connection with the Option. The Company shall have no obligation to deliver
shares of Stock until the tax withholding obligations of the Participating
Company Group have been satisfied by the Participant.

      4.5 CERTIFICATE REGISTRATION. Except in the event the Exercise Price is
paid by means of a Cashless Exercise, the certificate for the shares as to which
the Option is exercised shall be registered in the name of the Participant, or,
if applicable, in the names of the heirs of the Participant.

      4.6 RESTRICTIONS ON GRANT OF THE OPTION AND ISSUANCE OF SHARES. The grant
of the Option and the issuance of shares of Stock upon exercise of the Option
shall be subject to compliance with all applicable requirements of federal,
state or foreign law with respect to such securities. The Option may not be
exercised if the issuance of shares of Stock upon exercise would constitute a
violation of any applicable federal, state or foreign securities laws or other
law or regulations or the requirements of any stock exchange or market system
upon which the Stock may then be listed. In addition, the Option may not be
exercised unless (i) a registration statement under the Securities Act shall at
the time of exercise of the Option be in effect with respect to the shares
issuable upon exercise of the Option or (ii) in the opinion of legal counsel to
the Company, the shares issuable upon exercise of the Option may be issued in
accordance with the terms of an applicable exemption from the registration
requirements of the Securities Act. THE PARTICIPANT IS CAUTIONED THAT THE OPTION
MAY NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY,
THE PARTICIPANT MAY NOT BE ABLE TO EXERCISE THE OPTION WHEN DESIRED EVEN THOUGH
THE OPTION IS VESTED. The inability of the Company to obtain from any regulatory
body having jurisdiction the authority, if any, deemed by the Company's legal
counsel to be necessary to the lawful issuance and sale of any shares subject to
the Option 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. As a condition to the exercise of the Option, the Company may
require the Participant to satisfy any qualifications that may be necessary or
appropriate, to evidence compliance with any applicable law or regulation and to
make any representation or warranty with respect thereto as may be requested by
the Company.

      4.7 FRACTIONAL SHARES. The Company shall not be required to issue
fractional shares upon the exercise of the Option.

   5. NONTRANSFERABILITY OF THE OPTION.

      During the lifetime of the Participant, the Option shall be exercisable
only by the Participant or the Participant's guardian or legal representative.
The Option shall not be subject in any manner to anticipation, alienation, sale,
exchange, transfer, assignment, pledge, encumbrance, or garnishment by creditors
of the Participant or the Participant's beneficiary, except transfer by will or
by the laws of descent and distribution. Following the death of the Participant,
the Option, to the extent provided in Section 7, may be exercised by the
Participant's legal representative or by any person empowered to do so under the
deceased Participant's will or under the then applicable laws of descent and
distribution.

   6. TERMINATION OF THE OPTION.

      The Option shall terminate and may no longer be exercised after the first
to occur of (a) the close of business on the Option Expiration Date, (b) the
close of business on the last date for exercising the Option following
termination of the Participant's Service as described in Section 7, or (c) a
Change in Control to the extent provided in Section 8.

   7. EFFECT OF TERMINATION OF SERVICE.

      7.1 OPTION EXERCISABILITY. The Option shall terminate immediately upon the
Participant's termination of Service to the extent that it is then unvested and
shall be exercisable after the Participant's termination of Service to the
extent it is then vested only during the applicable time period as determined
below and thereafter shall terminate.

            (A) DISABILITY. If the Participant's Service terminates because of
the Disability of the Participant, the Option, to the extent unexercised and
exercisable for Vested Shares on the date on which the Participant's Service
terminated, may be exercised by the Participant (or the Participant's guardian
or legal representative) at any time prior to the expiration of twelve (12)
months after the date on which the Participant's Service terminated, but in any
event no later than the Option Expiration Date.

            (B) DEATH. If the Participant's Service terminates because of the
death of the Participant, the Option, to the extent unexercised and exercisable
for Vested Shares on the date on which the Participant's Service terminated, may
be exercised by the Participant's legal representative or other person who
acquired the right to exercise the Option by reason of the Participant's death
at any time prior to the expiration of twelve (12) months after the date on
which the Participant's Service terminated, but in any event no later than the
Option Expiration Date. The Participant's Service shall be deemed to have
terminated on account of death if the Participant dies within three (3) months
after the Participant's termination of Service.

            (C) TERMINATION FOR CAUSE. Notwithstanding any other provision of
this Option Agreement, if the Participant's Service is terminated for Cause, the
Option shall terminate and cease to be exercisable immediately upon such
termination of Service.

                                       4
<PAGE>

            (D) OTHER TERMINATION OF SERVICE. If the Participant's Service
terminates for any reason, except Disability, death or Cause, the Option, to the
extent unexercised and exercisable for Vested Shares by the Participant on the
date on which the Participant's Service terminated, may be exercised by the
Participant at any time prior to the expiration of three (3) months after the
date on which the Participant's Service terminated, but in any event no later
than the Option Expiration Date.

      7.2 EXTENSION IF EXERCISE PREVENTED BY LAW. Notwithstanding the foregoing
other than termination for Cause, if the exercise of the Option within the
applicable time periods set forth in Section 7.1 is prevented by the provisions
of Section 4.6, the Option shall remain exercisable until thirty (30) days after
the date the Participant is notified by the Company that the Option is
exercisable, but in any event no later than the Option Expiration Date.

   8. EFFECT OF CHANGE IN CONTROL.

      In the event of a Change in Control, the surviving, continuing, successor,
or purchasing entity or parent thereof, as the case may be (the "ACQUIROR"),
may, without the consent of the Participant, assume or continue in full force
and effect the Company's rights and obligations under the Option or any portion
thereof or substitute for the Option or any portion thereof a substantially
equivalent option for the Acquiror's stock. For purposes of this Section, the
Option shall be deemed assumed if, following the Change in Control, the Option
confers the right to receive, subject to the terms and conditions of the Plan
and this Option Agreement, for each share of Stock subject to the Option
immediately prior to the Change in Control, the consideration (whether stock,
cash, other securities or property or a combination thereof) to which a holder
of a share of Stock on the effective date of the Change in Control was entitled;
provided, however, that if such consideration is not solely common stock of the
Acquiror, the Board may, with the consent of the Acquiror, provide for the
consideration to be received upon the exercise of the Option, for each share of
Stock subject to the Option, to consist solely of common stock of the Acquiror
equal in Fair Market Value to the per share consideration received by holders of
Stock pursuant to the Change in Control. In the event the Acquiror elects not to
assume or continue the Company's rights and obligations under the Option or
substitute for the Option in connection with the Change in Control or implement
a Cash Out, any unvested and unexercised portion of the Option shall be
immediately exercisable and vested in full as of the date of the Change in
Control, provided that Participant's Service has not terminated prior to such
date. Any exercise of the Option that was permissible solely by reason of this
Section shall be conditioned upon the consummation of the Change in Control. The
Option shall terminate and cease to be outstanding effective as of the time of
consummation of the Change in Control to the extent that the Option is neither
assumed or continued by the Acquiror in connection with the Change in Control
nor exercised as of the date of the Change in Control. Notwithstanding the
foregoing, shares acquired upon exercise of the Option prior to the Change in
Control and any consideration received pursuant to the Change in Control with
respect to such shares shall continue to be subject to all applicable provisions
of this Option Agreement except as otherwise provided herein.

   9. ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE.

      Subject to any required action by the stockholders of the Company, in the
event of any change in the Stock effected without receipt of consideration by
the Company, whether through merger, consolidation, reorganization,
reincorporation, recapitalization, reclassification, stock dividend, stock
split, reverse stock split, split-up, split-off, spin-off, combination of
shares, exchange of shares, or similar change in the capital structure of the
Company, or in the event of payment of a dividend or distribution to the
stockholders of the Company in a form other than Stock (excepting normal cash
dividends) that has a material effect on the Fair Market Value of shares of
Stock, appropriate and proportionate adjustments shall be made in the number,
Exercise Price and kind of shares subject to the Option, in order to prevent
dilution or enlargement of the Participant's rights under the Option. For
purposes of the foregoing, conversion of any convertible securities of the
Company shall not be treated as "effected without receipt of consideration by
the Company." Any fractional share resulting from an adjustment pursuant to this
Section shall be rounded down to the nearest whole number and the Exercise Price
shall be rounded up to the nearest whole cent. In no event may the Exercise
Price be decreased to an amount less than the par value, if any, of the stock
subject to the Option. Such adjustments shall be determined by the Committee,
and its determination shall be final, binding and conclusive.

   10. RIGHTS AS A STOCKHOLDER, DIRECTOR OR EMPLOYEE.

      The Participant shall have no rights as a stockholder with respect to any
shares covered by the Option until the date of the issuance of the shares for
which the Option has been exercised (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company).
No adjustment shall be made for dividends, distributions or other rights for
which the record date is prior to the date the shares are issued, except as
provided in Section 9. If the Participant is an Employee, the Participant
understands and acknowledges that, except as otherwise provided in a separate,
written employment agreement between a Participating Company and the
Participant, the Participant's employment is "at will" and is for no specified
term. Nothing in this Option Agreement shall confer upon the Participant any
right to continue in the Service of a Participating Company or interfere in any
way with any right of the Participating Company Group to terminate the
Participant's Service as a Director or an Employee, as the case may be, at any
time.

   11. MISCELLANEOUS PROVISIONS.

      11.1 FURTHER INSTRUMENTS. The parties hereto agree to execute such further
instruments and to take such further action as may reasonably be necessary to
carry out the intent of this Option Agreement.

      11.2 BINDING EFFECT. Subject to the restrictions on transfer set forth
herein, this Option Agreement shall inure to the benefit of and be binding upon
the parties hereto and their respective heirs, executors, administrators,
successors and assigns.

      11.3 TERMINATION OR AMENDMENT. The Board may terminate or amend the Plan
or the Option at any time; provided, however, that except as provided in Section
8 in connection with a Change in Control, no such termination or amendment may
adversely affect the Option or any unexercised portion hereof without the
consent of the Participant unless such termination or amendment is necessary to
comply with any applicable law or government regulation. No amendment or
addition to this Option Agreement shall be effective unless in writing.

                                       6
