                   AMENDED AND RESTATED 1997 STOCK OPTION PLAN

        1. Purposes of the Plan. The purposes of this 1997 Stock Option Plan are
to attract and retain the best available personnel for positions of substantial
responsibility, to provide additional incentive to Employees and Consultants of
the Company and its Subsidiaries and to promote the success of the Company's
business. Options granted under the Plan may be Incentive Stock Options or
Nonstatutory Stock Options, as determined by the Administrator at the time of
grant of an Option and subject to the applicable provisions of Section 422 of
the Code and the regulations promulgated thereunder.

        2. Definitions. As used herein, the following definitions shall apply:

               (a) "Administrator" means the Board or any of its Committees
appointed pursuant to Section 4 of the Plan.

               (b) "Applicable Laws" means the legal requirements relating to
the administration of stock option plans under U.S. state corporate laws, U.S.
federal and state securities laws, the Code and the applicable laws of any
foreign country or jurisdiction where Options are, or will be, granted under the
Plan.

               (c) "Board" means the Board of Directors of the Company.

               (d) "Change in Control" shall mean an Ownership Change Event or a
series of related Ownership Change Events (collectively, the "Transaction")
wherein the shareholders of the Company immediately before the Transaction do
not retain immediately after the Transaction, in substantially the same
proportions as their ownership of shares of the Company's voting stock
immediately before the Transaction, direct or indirect beneficial ownership of
more than fifty percent (50%) of the total combined voting power of the
outstanding voting stock of the Company or the corporation or corporations to
which the assets of the Company were transferred (the "Transferee
Corporation(s)"), as the case may be. For purposes of the preceding sentence,
indirect beneficial ownership shall include, without limitation, an interest
resulting from ownership of the voting stock of one or more corporations which,
as a result of the Transaction, own the Company or the Transferee
Corporation(s), as the case may be, either directly or through one or more
subsidiary corporations. The Board shall have the right to determine whether
multiple sales or exchanges of the voting stock of the Company or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

               (e) "Code" means the Internal Revenue Code of 1986, as amended.

               (f) "Committee" means a Committee appointed by the Board of
Directors in accordance with Section 4 of the Plan.

compensated for such services or not. If the Company registers any class of any
equity security pursuant to the Exchange Act, the term Consultant shall
thereafter not include Directors who are not compensated for their services or
are paid only a Director's fee by the Company.

               (j) "Continuous Status as an Employee or Consultant" means that
the employment or consulting relationship with the Company, any Parent or
Subsidiary is not interrupted or terminated. Continuous Status as an Employee or
Consultant shall not be considered interrupted in the case of (i) any leave of
absence approved by the Company or (ii) transfers between locations of the
Company or between the Company, its Parent, any Subsidiary, or any successor. A
leave of absence approved by the Company shall include sick leave, military
leave, or any other personal leave approved by an authorized representative of
the Company. For purposes of Incentive Stock Options, no such leave may exceed
90 days, unless reemployment upon expiration of such leave is guaranteed by
statute or contract, including Company policies. If reemployment upon expiration
of a leave of absence approved by the Company is not so guaranteed, on the 91st
day of such leave any Incentive Stock Option held by the Optionee shall cease to
be treated as an Incentive Stock Option and shall be treated for tax purposes as
a Nonstatutory Stock Option.

Company.

               (l) "Employee" means any person, including Officers and
Directors, employed by the Company or any Parent or Subsidiary of the Company.
The payment of a Director's fee by the Company shall not be sufficient to
constitute "employment" by the Company.

stock exchange or a national market system, including without limitation The
Nasdaq National Market or The Nasdaq SmallCap Market of The Nasdaq Stock Market,
its Fair Market Value shall be the closing sales price for such stock (or the
closing bid, if no sales were reported) as quoted on such exchange or system for
the last market trading day prior to the time of determination, as reported in
The Wall Street Journal or such other source as the Administrator deems
reliable;

                      (ii) If the Common Stock is regularly quoted by a
recognized securities dealer but selling prices are not reported, its Fair
Market Value shall be the mean between the high bid and low asked prices for the
Common Stock on the last market trading day prior to the day of determination;
or

                      (iii)  In the absence of an established market for the
Common Stock, the Fair Market Value thereof shall be determined in good faith by
the Administrator.

series of related transactions by the shareholders of the Company of more than
fifty percent (50%) of the voting stock of the Company;

                      (ii) a merger or consolidation in which the Company is a
party;

                      (iii)  the sale, exchange, or transfer of all or
substantially all of the assets of the Company; or

                      (iv) a liquidation or dissolution of the Company.

               (v) "Parent" means a "parent corporation," whether now or

        3. Stock Subject to the Plan. Subject to the provisions of Section 12 of
the Plan, the maximum aggregate number of Shares that may be subject to option
and sold under the Plan is Five Million (5,000,000) Shares. The Shares may be
authorized but unissued, or reacquired Common Stock.

        If an Option expires or becomes unexercisable without having been
exercised in full, or is surrendered pursuant to an option exchange program, the
unpurchased Shares that were subject thereto shall become available for future
grant or sale under the Plan (unless the Plan has terminated). However, Shares
that have actually been issued under the Plan, upon exercise of an Option, shall
not be returned to


   4
the Plan and shall not become available for future distribution under the Plan,
except that if Shares are repurchased by the Company at their original purchase
price, and the original purchaser of such Shares did not receive any benefits of
ownership of such Shares, such Shares shall become available for future grant
under the Plan. For purposes of the preceding sentence, voting rights shall not
be considered a benefit of Share ownership.

        4. Administration of the Plan.

               (a) Initial Plan Procedure. Prior to the date, if any, upon which
the Company becomes subject to the Exchange Act, the Plan shall be administered
by the Board or a Committee appointed by the Board.

               (b) Plan Procedure after the Date, if any, upon which the Company
Becomes Subject to the Exchange Act.

                      (i)    Multiple Administrative Bodies.  If permitted by
Rule 16b-3, the Plan may be administered by different bodies with respect to
Directors, Officers and Employees who are neither Directors nor Officers.

                      (ii)   Administration with Respect to Directors and
Officers. With respect to grants of Options to Employees who are also Officers
or Directors of the Company, the Plan shall be administered by (A) the Board if
the Board may administer the Plan in compliance with the rules under Rule 16b-3
promulgated under the Exchange Act or any successor thereto ("Rule 16b-3")
relating to the disinterested administration of employee benefit plans under
which Section 16(b) exempt discretionary grants and awards of equity securities
are to be made, or (B) a Committee designated by the Board to administer the
Plan, which Committee shall be constituted to comply with the rules under Rule
16b-3 relating to the disinterested administration of employee benefit plans
under which Section 16(b) exempt discretionary grants and awards of equity
securities are to be made. Once appointed, such Committee shall continue to
serve in its designated capacity until otherwise directed by the Board. From
time to time the Board may increase the size of the Committee and appoint
additional members thereof, remove members (with or without cause) and appoint
new members in substitution therefor, fill vacancies, however caused, and remove
all members of the Committee and thereafter directly administer the Plan, all to
the extent permitted by the rules under Rule 16b-3 relating to the disinterested
administration of employee benefit plans under which Section 16(b) exempt
discretionary grants and awards of equity securities are to be made.

                      (iii) Administration with Respect to Other Employees and
Consultants. With respect to grants of Options and to Employees or Consultants
who are neither Directors nor Officers of the Company, the Plan shall be
administered by (A) the Board or (B) a Committee designated by the Board, which
committee shall be constituted in such a manner as to satisfy Applicable Laws.
Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused, and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by the Applicable Laws.


   5

               (c) Powers of the Administrator. Subject to the provisions of the
Plan and, in the case of a Committee, the specific duties delegated by the Board
to such Committee, and subject to the approval of any relevant authorities,
including the approval, if required, of any stock exchange upon which the Common
Stock is listed, the Administrator shall have the authority in its discretion:

                      (i)    to determine the Fair Market Value of the Common
Stock, in accordance with Section 2(m) of the Plan;

                      (ii)   to select the Consultants and Employees to whom
Options may from time to time be granted hereunder;

                      (iii) to determine whether and to what extent Options are
granted hereunder;

                      (iv)   to determine the number of Shares to be covered by
each such award granted hereunder;

                      (v) to approve forms of agreement for use under the Plan;

                      (vi)   to determine the terms and conditions of any award
granted hereunder;

                      (vii) to determine whether and under what circumstances an
Option may be settled in cash under subsection 9(f) instead of Common Stock;

                      (viii) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option has declined since the date the Option was granted;

                      (ix) to provide for the early exercise of Options for the
purchase of unvested shares subject to such terms and conditions as the
Administrator may determine; and

                      (x) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan.

               (d) Effect of Administrator's Decision. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options.

        5. Eligibility.

               (a) Nonstatutory Stock Options may be granted to Employees and
Consultants. Incentive Stock Options may be granted only to Employees. An
Employee or Consultant who has been granted an Option may, if otherwise
eligible, be granted additional Options.

               (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designation, to the extent that the aggregate Fair
Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock


   6
Options. For purposes of this Section 5(b). Incentive Stock Options shall be
taken into account in the order in which they were granted. The Fair Market
Value of the Shares shall be determined as of the time the Option with respect
to such Shares is granted.

               (c) Neither the Plan nor any Option shall confer upon any
Optionee any right with respect to continuation of his or her employment or
consulting relationship with the Company, nor shall it interfere in any way with
his or her right or the Company's right to terminate his or her employment or
consulting relationship at any time, with or without cause.

               (d) Upon the Company or a successor corporation issuing any class
of common equity securities required to be registered under Section 12 of the
Exchange Act or upon the Plan being assumed by a corporation having a class of
common equity securities required to be registered under Section 12 of the
Exchange Act, the following limitations shall apply to grants of Options to
Employees:

                      (i) The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 11.

                      (ii) If an Option is cancelled in the same fiscal year of
the Company in which it was granted (other than in connection with a transaction
described in Section 11), the cancelled Option shall be counted against the
limit set forth in subsection (i) above. For this purpose, if the exercise price
of an Option is reduced, such reduction will be treated as a cancellation of the
Option and the grant of a new Option.

        6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company, as described in Section 17 of the Plan. It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 13 of the Plan.

        7. Term of Option. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof. In the case of an Incentive Stock
Option granted to an Optionee who, at the time the Option is granted, owns stock
representing more than ten percent (10%) of the voting power of all classes of
stock of the Company or any Parent or Subsidiary, the term of the Option shall
be five (5) years from the date of grant thereof or such shorter term as may be
provided in the Option Agreement.

        8. Option Exercise Price and Consideration.

               (a) The per share exercise price for the Shares to be issued upon
exercise of an Option shall be such price as is determined by the Administrator,
but shall be subject to the following:

                      (i) In the case of an Incentive Stock Option

                             (A) granted to an Employee who, at the time of
grant of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the per Share exercise price shall be no less than 110% of the Fair Market Value
per Share on the date of grant.

   7

                             (B) granted to any other Employee, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                      (ii) In the case of a Nonstatutory Stock Option

                             (A) granted to a person who, at the time of grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the per Share exercise price shall be no less than 110% of the Fair Market Value
per Share on the date of the grant.

                             (B) granted to any other person, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share on
the date of grant.

               (b) The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant). Such consideration may consist of (1) cash,
(2) check, (3) promissory note, (4) other Shares that (x) in the case of Shares
acquired upon exercise of an Option, have been owned by the Optionee for more
than six months on the date of surrender, and (y) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
a broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (6) any combination of the foregoing methods of payment. In
making its determination as to the type of consideration to accept, the
Administrator shall consider if acceptance of such consideration may be
reasonably expected to benefit the Company.

        9. Exercise of Option.

               (a) Procedure for Exercise; Rights as a Shareholder. Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan.

               An Option may not be exercised for a fraction of a Share.

               An Option shall be deemed to be exercised when written notice of
such exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and fulfill payment for the
Shares with respect to which the Option is exercised has been received by the
Company. Full payment may, as authorized by the Administrator, consist of any
consideration and method of payment allowable under Section 8(b) hereof. Until
the issuance (as evidenced by the appropriate entry on the books of the Company
or of a duly authorized transfer agent of the Company) of the stock certificate
evidencing such Shares, no right to vote, receive dividends or any other rights
as a shareholder shall exist with respect to the Optioned Stock, notwithstanding
the exercise of the Option. The Company shall issue (or cause to be issued) such
stock certificate promptly upon exercise of the Option. No adjustment shall be
made for a dividend or other right for which the record date is prior to the
date the stock certificate is issued, except as provided in Section 11 hereof.


   8

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares that thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

               (b) Termination of Employment or Consulting Relationship. In the
event of termination of an Optionee's Continuous Status as an Employee or
Consultant (but not in the event of an Optionee's change of status from Employee
to Consultant (in which case an Employee's Incentive Stock Option shall
automatically convert to a Nonstatutory Stock Option on the date three (3)
months and one day following such change of status) or from Consultant to
Employee), such Optionee may, but only within such period of time as is
determined by the Administrator, of at least thirty (30) days, with such
determination in the case of an Incentive Stock Option not exceeding three (3)
months after the date of such termination (but in no event later than the
expiration date of the term of such Option as set forth in the Option
Agreement), exercise his or her Option to the extent that the Optionee was
entitled to exercise it at the date of such termination. To the extent that the
Optionee was not entitled to exercise the Option at the date of such
termination, or if the Optionee does not exercise such Option to the extent so
entitled within the time specified herein, the Option shall terminate.

               (c) Disability of Optionee. In the event of termination of an
Optionee's Continuous Status as an Employee or Consultant as a result of his or
her disability, the Optionee may, but only within twelve (12) months from the
date of such termination (and in no event later than the expiration date of the
term of such Option as set forth in the Option Agreement), exercise the Option
to the extent otherwise entitled to exercise it at the date of such termination.
If such disability is not a "disability" as such term is defined in Section
22(e)(3) of the Code, in the case of an Incentive Stock Option such Incentive
Stock Option shall automatically cease to be treated as an Incentive Stock
Option and shall be treated for tax purposes as a Nonstatutory Stock Option on
the day three months and one day following such termination. To the extent that
the Optionee was not entitled to exercise the Option at the date of termination,
or if the Optionee does not exercise such Option to the extent so entitled
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

               (d) Death of Optionee. In the event of the death of an Optionee,
the Option may be exercised at any time within twelve (12) months following the
date of death (but in no event later than the expiration of the term of such
Option as set forth in the Notice of Grant) by the Optionee's estate or by a
person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent that the Optionee was entitled to exercise the Option on
the date of death. If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan. If, after the
Optionee's death, the Optionee's estate or a person who acquires the right to
exercise the Option by bequest or inheritance does not exercise the Option
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

               (e) Rule 16b-3. Options granted to persons subject to Section
16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.



   9

               (f) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted, based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

        10. Non-Transferability of Options. Options may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.

        11. Adjustments Upon Changes in Capitalization or Change of Control.

               (a) Changes in Capitalization. Subject to any required action by
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock that have been
authorized for issuance under the Plan but as to which no Option has yet been
granted or that has been returned to the Plan upon cancellation or expiration of
an Option, as well as the price per share of Common Stock covered by each such
outstanding Option, shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the number of issued
shares of Common Stock effected without receipt of consideration by the Company.
The conversion of any convertible securities of the Company shall not be deemed
to have been "effected without receipt of consideration." Such adjustment shall
be made by the Board, whose determination in that respect shall be final,
binding and conclusive. Except as expressly provided herein, no issuance by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall
be made with respect to, the number or price of shares of Common Stock subject
to an Option.

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify the
Optionee at least fifteen (15) days prior to such proposed action. To the extent
it has not been previously exercised, the Option shall terminate immediately
prior to the consummation of such proposed action.

               (c) Change in Control. A Change in Control shall have the
following consequences with respect to Options outstanding immediately prior
thereto:

                      (i) The surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "Acquiring
Corporation"), may either assume the Company's rights and obligations under
outstanding Options or substitute for outstanding Options substantially
equivalent options for the Acquiring Corporation's stock. For purposes of this
Section 11(c), an Option shall be deemed assumed if, following the Change in
Control, the Option confers the right to purchase in accordance with its terms
and conditions, for each share of Stock subject to the Option immediately prior
to the Change in Control, the consideration (whether stock, cash or other
securities or property) to which a holder of a share of Stock on the effective
date of the Change in Control was entitled. Any Options which are neither
assumed or substituted for by the Acquiring Corporation in connection with the
Change in Control nor exercised as of the date of the Change in Control shall
terminate and cease to be outstanding effective as of the date of the Change in
Control.

   10

                      (ii) In addition to the foregoing, any unexercisable or
unvested portion of each outstanding Option held by a Director who is not an
Employee shall be immediately exercisable and vested in full as of the date ten
(10) days prior to the date of the Change in Control.

                      (iii) In the event the Acquiring Corporation elects not to
assume or substitute for outstanding Options in connection with the Change in
Control, for purposes of determining the exercisability and vesting of the
outstanding Options, each Optionee shall be credited with an additional twelve
(12) months of vesting effective as of the date ten (10) days prior to the date
of the Change in Control.

                      (iv)   For purposes of determining the exercisability and
vesting of each outstanding Option which was assumed or substituted by the
Acquiring Corporation in connection with the Change in Control, each Optionee
who remains in Continuous Status as an Employee or Consultant with the Acquiring
Corporation on the date occurring six (6) months after the Change in Control
shall be credited with an additional twelve (12) months of vesting effective as
of such date.

                      (v)    The exercise or vesting of any Option that was
permissible solely by reason of this Section 11(c) shall be conditioned upon the
consummation of the Change in Control.

                      (vi) Notwithstanding the foregoing, shares acquired upon
exercise of an 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 the Option Agreement
evidencing such Option except as otherwise provided in such Option Agreement.
Furthermore, notwithstanding the foregoing, if the corporation the stock of
which is subject to the outstanding Options immediately prior to an Ownership
Change Event described in Section 2(u) constituting a Change in Control is the
surviving or continuing corporation and immediately after such Ownership Change
Event less than fifty percent (50%) of the total combined voting power of its
voting stock is held by another corporation or by other corporations that are
members of an affiliated group within the meaning of Section 1504(a) of the Code
without regard to the provisions of Section 1504(b) of the Code, the outstanding
Options shall not terminate unless the Board otherwise provides in its sole
discretion.

        12. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Employee or Consultant to
whom an Option is so granted within a reasonable time after the date of such
grant.

        13. Amendment and Termination of the Plan.

               (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or discontinue the Plan, but no amendment, alteration, suspension
or discontinuation shall be made that would impair the rights of any Optionee
under any grant theretofore made, without his or her consent. In addition, to
the extent necessary and desirable to comply with Rule 16b-3 under the Exchange
Act or with Section 422 of the Code (or any other applicable law or regulation,
including the requirements of the NASD or an established stock exchange), the
Company shall obtain shareholder approval of any Plan amendment in such a manner
and to such a degree as required.

               (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if


   11
this Plan had not been amended or terminated, unless mutually agreed otherwise
between the Optionee and the Administrator, which agreement must be in writing
and signed by the Optionee and the Company.

        14. Conditions upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

        As a condition to the exercise of an Option, the Company may require the
person exercising such Option to represent and warrant at the time of any such
exercise that the Shares are being purchased only for investment and without any
present intention to sell or distribute such Shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned relevant provisions of law.

        15. Reservation of Shares. The Company, during the term of this Plan,
shall at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, 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.

        16. Agreements. Options shall be evidenced by written agreements in such
form as the Administrator shall approve from time to time.

        17. Shareholder Approval. Continuance of the Plan shall be subject to
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such shareholder approval shall be obtained
in the degree and manner required under Applicable Laws and the rules of any
stock exchange upon which the Common Stock is listed.

        18. Information to Optionees and Purchasers. The Company shall provide
to each Optionee and to each individual who acquires Shares pursuant to the
Plan, not less frequently than annually during the period such Optionee or
purchaser has one or more Options outstanding, and, in the case of an individual
who acquires Shares pursuant to the Plan, during the period such individual owns
such Shares, copies of annual financial statements. The Company shall not be
required to provide such statements to key employees whose duties in connection
with the Company assure their access to equivalent information.
