federal tax consequences of exercise of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE OPTIONEE SHOULD

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(a)</FONT><FONT
SIZE=2><I>&nbsp;&nbsp;Exercise of ISO.</I></FONT><FONT SIZE=2>&nbsp;If this Option qualifies as an ISO, there will be no regular federal income tax
liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to the alternative minimum tax in the year of exercise. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(b)</FONT><FONT
SIZE=2><I>&nbsp;&nbsp;Exercise of Nonstatutory Stock Option.</I></FONT><FONT SIZE=2>&nbsp;There may be a regular federal income tax liability upon the
exercise of a Nonstatutory Stock Option. The Optionee will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market
Value of the Shares on the date of exercise over the Exercise Price. If Optionee is an Employee or a former Employee, the Company will be required to withhold from Optionee's compensation or collect
from
Optionee and pay to the applicable taxing authorities an amount in cash equal to a percentage of this compensation income at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of exercise. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(c)</FONT><FONT
SIZE=2><I>&nbsp;&nbsp;Disposition of Shares.</I></FONT><FONT SIZE=2>&nbsp;In the case of an NSO, if Shares are held for at least one year, any gain
realized on disposition of the Shares will be treated as long-term capital gain for federal income tax purposes. In the case of an ISO, if Shares transferred pursuant to the Option are held for at
least one year after exercise and of at least two years after the Date of Grant, any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal income tax
purposes. If Shares purchased under an ISO are disposed of within one year after exercise or two years after the Date of Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference between the Exercise Price and the lesser of (1)&nbsp;the Fair Market Value of the Shares on the date of exercise, or
(2)&nbsp;the sale price of the Shares. Any additional gain will be taxed as capital gain, short-term or long-term depending on the period that the ISO Shares were held. </FONT></P>


<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(d)</FONT><FONT
SIZE=2><I>&nbsp;&nbsp;Notice of Disqualifying Disposition of ISO Shares.</I></FONT><FONT SIZE=2>&nbsp;If the Option granted to Optionee herein is an
ISO, and if Optionee sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (1)&nbsp;the date two years after the Date of Grant, or (2)&nbsp;the
date one year after the date of exercise, the Optionee shall immediately notify the Company in writing of such disposition. Optionee agrees that Optionee may be subject to income tax withholding by
the Company on the compensation income recognized by the Optionee. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;In
connection with the purchase of the above-listed Securities, the undersigned Optionee represents to the Company the following: </FONT></P>

<UL>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;Optionee
is aware of the Company's business affairs and financial condition and has acquired sufficient information about the Company to reach an informed and
knowledgeable decision to acquire
the Securities. Optionee is acquiring these Securities for investment for Optionee's own account only and not with a view to, or for resale in connection with, any "distribution" thereof within the
meaning of the Securities Act of 1933, as amended (the "Securities Act"). </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;Optionee
acknowledges and understands that the Securities constitute "restricted securities" under the Securities Act and have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of Optionee's investment intent as expressed herein. In this
connection, Optionee understands that, in the view of the Securities and Exchange Commission, the statutory basis for such exemption may be unavailable if Optionee's representation was predicated
solely upon a present intention to hold these Securities for the minimum capital gains period specified under tax statutes, for a deferred sale, for or until an increase or decrease in the market
price of the Securities, or for a period of one year or any other fixed period in the future. Optionee further understands that the Securities must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is available. Optionee further acknowledges and understands that the Company is under no obligation to register the
Securities. Optionee understands that the certificate evidencing the Securities will be imprinted with a legend which prohibits the transfer of the Securities unless they are registered or such
registration is not required in the opinion of counsel satisfactory to the Company, a legend prohibiting their transfer without the consent of the Commissioner of Corporations of the State of
California and any other legend required under applicable state securities laws. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Optionee
is familiar with the provisions of Rule&nbsp;701 and Rule&nbsp;144, each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from the issuer thereof, in a non-public offering subject to the satisfaction of certain conditions. Rule&nbsp;701 provides
that if the issuer qualifies under Rule&nbsp;701 at the time of the grant of the Option to the Optionee, the exercise will be exempt from registration under the Securities Act. In the event the
Company becomes subject to the reporting requirements of Section 13 or 15(d)&nbsp;of the Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer period as any market stand-off
agreement may require) the Securities exempt under Rule&nbsp;701 may be resold, subject to the satisfaction of certain of the conditions specified by Rule&nbsp;144, including: (1)&nbsp;the
resale being made through a broker in an unsolicited "broker's </FONT></P>

transaction" or in transactions directly with a market maker (as said term is defined under the Securities Exchange Act of 1934); and, in the case of an affiliate, (2)&nbsp;the availability of
certain public information about the Company, (3)&nbsp;the amount of Securities being sold during any three month period not exceeding the limitations specified in Rule&nbsp;144(e), and
(4)&nbsp;the timely filing of a Form 144, if applicable. </FONT></P>

</UL>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;In
the event that the Company does not qualify under Rule&nbsp;701 at the time of grant of the Option, then the Securities may be resold in certain limited circumstances subject to
the provisions of Rule&nbsp;144, which requires the resale to occur not less than one year after the later of the date the Securities were sold by the Company or the date the Securities were sold by
an affiliate of the Company, within the meaning of Rule&nbsp;144; and, in the case of acquisition of the Securities by an affiliate, or by a non-
affiliate who subsequently holds the Securities less than two years, the satisfaction of the conditions set forth in sections (1), (2), (3)&nbsp;and (4)&nbsp;of the paragraph immediately above. </FONT></P>

<UL>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;Optionee
further understands that in the event all of the applicable requirements of Rule&nbsp;701 or 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules&nbsp;144 and 701 are not exclusive, the Staff of the
Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to
Rules&nbsp;144 or 701 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective
brokers who participate in such transactions do so at their own risk. Optionee understands that no assurances can be given that any such other registration exemption will be available in such event. </FONT></P>
