entitled to receive in respect of such shares any securities, cash or other

immediately prior to such Reorganization, and any adjustments will be made to
the terms of the Option in the sole discretion of the Administering Body as it

                  (ii) state the number of vested shares with respect to which
         the Option is being exercised (the "Optioned Shares");

                  (iii) state the date upon which the Optionee desires to
         consummate the purchase of the Optioned Shares (which date must be
         prior to the termination of such Option and no later than 30 days after
         the date of receipt of such Notice);

                  (iv) include any representations of the Optionee required
         under Section 8(c); and

                  (v) if the Option shall be exercised pursuant to Section 9 by
         any person other than the Optionee, include evidence to the
         satisfaction of the Administering Body of the right of such person to
         exercise the Option.

         (b) Payment of the Option Price for the Optioned Shares shall be made
in U.S. dollars by personal check, bank draft or money order payable to the
order of the Corporation or by wire transfer.

         (c) The Corporation shall issue a stock certificate in the name of the
Optionee (or such other person exercising the Option in accordance with the
provisions of Section 9) for the Optioned Shares as soon as practicable after
receipt of the Notice and payment of the aggregate Option Price for such shares.

         6. NO RIGHTS AS A STOCKHOLDER. The Optionee shall have no rights as a
stockholder of the Corporation with respect to any Optioned Shares until the
date the Optionee or his nominee (which, for purposes of this Agreement, shall
include any third party agent selected by the Administering Body to hold such
Optioned Shares on behalf of the Optionee), guardian or legal representative is
the holder of record of such Optioned Shares.

         7. ADJUSTMENTS.

         (a) If at any time while the Option is outstanding, (1) there shall be
any increase or decrease in the number of issued and outstanding shares of
Common Stock through the declaration of a stock dividend, stock split,
combination of shares or through any recapitalization resulting in a stock
split-up, spin-off, combination or exchange of shares of Common Stock or (2) the
value of the outstanding shares of Common Stock is reduced by reason of an
extraordinary cash dividend, THEN, and in each such event, appropriate
adjustment shall be made in the number of shares and the exercise price per
share covered by the Option, so that the same proportion of the Corporation's
issued and outstanding shares of Common Stock shall remain subject to purchase
at the same aggregate exercise price.

convertible into shares of capital stock of any class, either in connection with
a direct sale or upon the exercise of rights or warrants to subscribe therefor,
or upon conversion of shares or obligations of the Corporation convertible into
such shares or other securities, shall not affect, and no adjustment by reason
thereof shall be made with respect to, the number of or exercise price of shares
of Common Stock covered by the Option.

         (c) Without limiting the generality of the foregoing, the existence of
the Option shall not affect in any manner the right or power of the Corporation
to make, authorize or consummate (i) any or all adjustments, recapitalizations,
reorganizations or other changes in the Corporation's capital structure or its
business; (ii) any merger or consolidation of the Corporation; (iii) any issue
by the Corporation of debt securities, or preferred or preference stock that

         (a) The Option shall be exercisable only in accordance with this

period when the Option may be exercised and the number of shares of Common Stock
that may be acquired upon exercise.

         (b) The Option may not be exercised as to less than 100 shares of
Common Stock at any one time unless less than 100 shares of Common Stock remain
to be purchased upon the exercise of the Option.

         (c) To exercise the Option, the Optionee shall follow the provisions of
Section 5. Upon the exercise of the Option at a time when there is not in effect
a registration statement under the Securities Act of 1933, as amended (the
"Securities Act") relating to the shares of Common Stock issuable upon exercise
of the Option, the Administering Body in its discretion may, as a condition to
the exercise of the Option, require the Optionee (i) to represent in writing
that the shares of Common Stock received upon exercise of the Option are being
acquired for investment and not with a view to distribution and (ii) to make
such other representations and warranties as are deemed appropriate by counsel
to the Corporation. No Option may be exercised and no shares of Common Stock
shall be issued and delivered upon the exercise of the Option unless and until
the Corporation and/or the Optionee shall have complied with all applicable
federal or state registration, listing and/or qualification requirements and all
other requirements of law or of any regulatory agencies having jurisdiction.

         (d) Stock certificates representing shares of Common Stock acquired
upon the exercise of the Option that have not been registered under the
Securities Act shall, if required by the Administering Body, bear an appropriate
legend which may, at the discretion of the Administering Body, take the
following form:

                                       4

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT").

         ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES
         UNDER THE ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION OR AN
         OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH
         REGISTRATION IS NOT REQUIRED."

         (e) The exercise of each Option and the issuance of shares in
connection with the exercise of an Option shall, in all cases, be subject to
each of the following conditions: (i) compliance with the terms of the Plan and
this Agreement, (ii) the satisfaction of withholding tax or other withholding
liabilities, (iii) as necessary, the listing, registration or qualification of
any to-be-issued shares upon any securities exchange, The Nasdaq Stock Market or
other trading or quotation system or under any federal or state law and (iv) the
consent or approval of any regulatory body. The Administering Body shall in its
sole discretion determine whether one or more of these conditions is necessary
or desirable to be satisfied in connection with the exercise of an Option and
prior to the delivery or purchase of shares pursuant to the exercise of an
Option. The exercise of an Option shall not be effective unless and until such
condition(s) shall have been satisfied or the Administering Body shall have
waived such conditions, in its sole discretion.

         9. RESTRICTION ON TRANSFER. The Option may not be assigned or
transferred except by will or by the laws of descent and distribution or
pursuant to a qualified domestic relations order as defined in the IRC, and may
be exercised during the lifetime of the Optionee only by the Optionee or the
Optionee's guardian or legal representative or assignee pursuant to a qualified
domestic relations order. If the Optionee dies, the Option shall thereafter be
exercisable, during the period specified in Section 4(a), by his executors or
administrators or by a person who acquired the right to exercise such Option by
bequest or inheritance to the full extent to which the Option was exercisable by
the Optionee at the time of his death. If the Optionee becomes inflicted with a
Permanent Disability, the Option shall thereafter be exercisable, during the
period specified in Section 4(a), by his legal representatives to the full
extent to which the Option was exercisable by the Optionee at the time of his
Permanent Disability. The Option shall not be subject to execution, attachment
or similar process. Any attempted assignment or transfer of the Option contrary
to the provisions hereof, and the levy of any execution, attachment or similar
process upon the Option, shall be null and void and without effect.
