      YOUR PARTICULAR ATTENTION IS DIRECTED TO SECTION 7 OF THE PLAN WHICH
DESCRIBES CERTAIN IMPORTANT CONDITIONS RELATING TO FEDERAL AND STATE SECURITIES
LAWS THAT MUST BE SATISFIED BEFORE THE OPTION CAN BE EXERCISED AND BEFORE THE
COMPANY CAN ISSUE ANY SHARES TO YOU. THE COMPANY HAS NO OBLIGATION TO REGISTER

NEVER REGISTERS THE SHARES, YOU WILL NOT BE ABLE TO EXERCISE THE OPTION UNLESS
AN EXEMPTION FROM REGISTRATION IS AVAILABLE. AT THE PRESENT TIME, EXEMPTIONS

ADDITION, YOU SHOULD CONSULT WITH YOUR TAX ADVISOR IN ADVANCE CONCERNING THE
RAMIFICATIONS TO YOU OF HOLDING OR EXERCISING YOUR OPTIONS OR HOLDING OR SELLING
THE SHARES UNDERLYING SUCH OPTIONS.

      Administrator in accordance with the Plan, equal to the aggregate Exercise
      Price for the number of shares as to which the option is being exercised;

      Upon receipt of written Notice of Exercise and payment and delivery of any
other required documentation, the Company shall deliver to the person exercising
the option a certificate or certificates for the appropriate number of shares of

obligation to issue or transfer Common Stock upon exercise of this option that
you pay, or make provision satisfactory to the Company for the payment of, any
taxes which the Company is obligated to collect with respect to the issue or
transfer of Common Stock upon exercise.

      Termination: Your option will terminate immediately upon termination for
cause, as defined in the Plan, or ninety (90) days after cessation of your
relationship with the Company or a related corporation, unless cessation is due
to death or total disability, in which case (i) the portion of this option which
is vested at the time of such termination plus (ii) a pro rata amount of any
portion of this option subject to a periodic vesting schedule that would have
accrued on the next vesting date had you not died or become totally disabled
shall terminate one year after cessation of such relationship. All unvested
options, except those discussed under (ii) of the preceding sentence, will
terminate immediately upon the cessation of your relationship with the Company
or a related corporation for any reason, including, without limitation,
termination for cause, resignation, death or disability.

      Transfer of Option: The option is not transferable except by will or by
the applicable laws of descent and distribution.

      Hold back: In connection with any underwritten public offering by the
Company of its equity securities pursuant to an effective registration statement
filed under the Securities Act, including the Company's initial public offering,
Grantee shall not directly or indirectly sell, make any short sale of, loan,
hypothecate, pledge, offer, grant or sell any option or other contract for the
purchase of, purchase any option or other contract for the sale of, or otherwise
dispose of or transfer, or agree to engage in any of the foregoing transactions
with respect to, any option shares acquired under this Agreement without the
prior written consent of the Company or its underwriters. The period of such
restriction (the "Blackout Period") shall be in effect for such period of time
following the date of the final prospectus for the offering as may be requested
by the Company or such underwriters. In no event, however, shall such period
exceed 180 days. In the event of the declaration of a stock dividend, a
spin-off, a stock split, an adjustment in conversion ratio, a recapitalization
or a similar transaction affecting the Company's outstanding shares of Common
Stock without receipt of consideration, any new, substituted or additional
securities which are by reason of such transaction distributed with respect to
any option shares subject to the Blackout Period, or into which such option
shares thereby become convertible, shall immediately be subject to the
restrictions set forth herein. In order to enforce such restriction, the Company
may impose stop-transfer instructions with respect to the option shares acquired
under this Agreement until the end of the applicable stand-off period. The
Company's underwriters shall be beneficiaries of the agreement set forth in this
subsection. This subsection shall not apply to option shares registered in the
public offering under the Securities Act, and Grantee shall be subject to this
subsection only if the directors and officers of the Company are subject to
similar arrangements.

the President, and, if to you, shall be delivered personally or mailed to you at

      It is the intention of the Company that this Plan comply in all respects
with Section 16(b) and Rule 16b-3 under the Securities Exchange Act of 1934 (the

16b-3 under the Exchange Act. Notwithstanding anything in the Plan to the
contrary, the Board, in its absolute discretion, may bifurcate the Plan so as to
