designated capacity until otherwise directed by the Board.  The Board may
increase the size of the Committee and appoint additional members, remove
members (with or without cause) and substitute new members, fill vacancies
(however caused), and remove all members of the Committee and thereafter
directly administer the Plan, all to the extent permitted by Applicable Laws.

         (b)  POWERS OF THE ADMINISTRATOR.  Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, 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(l) of the Plan;

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

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

                   (iv)      to determine the number of shares of Common Stock
to be covered by each Option granted hereunder;

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

                   (vi)      to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder.  Such
terms and conditions include, but are not limited to, the exercise price, the
time or times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                   (vii)     to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;

                   (viii)    to prescribe, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of qualifying for preferred tax treatment
under foreign tax laws;

                   (ix)      to modify or amend each Option (subject to Section
15(b) of the Plan), including the discretionary authority to extend the post-
termination exercisability period of Options;


                                         -3-



                   (x)       to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option previously
granted by the Administrator;

                   (xi)      to make all other determinations deemed necessary
or advisable for administering the Plan.

         (c)  EFFECT OF ADMINISTRATOR'S DECISION.  The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

    5.   ELIGIBILITY.  Nonstatutory Stock Options may be granted to Employees
and Consultants.  If otherwise eligible, an Employee or Consultant who has been
granted an Option may be granted additional Options.  Notwithstanding anything
to the contrary contained in the Plan, Options may not be granted to officers or
Directors under this Plan.

    6.   LIMITATIONS.  Neither the Plan nor any Option shall confer upon an
Optionee any right with respect to continuing the Optionee's employment or
consulting relationship with the Company, nor shall they interfere in any way
with the Optionee's right or the Company's right to terminate such employment or
consulting relationship at any time, with or without cause.

    7.   TERM OF PLAN.  The Plan shall become effective upon its adoption by
the Board.  It shall continue in effect until terminated under Section 15 of the
Plan.

    8.   TERM OF OPTION.  The term of each Option shall be stated in the Notice
of Grant.

    9.   OPTION EXERCISE PRICE AND CONSIDERATION.

         (a)  EXERCISE PRICE.  The per share exercise price for the Shares to
be issued pursuant to exercise of an Option shall be determined by the
Administrator.

         (b)  WAITING PERIOD AND EXERCISE DATES.  At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

         (c)  FORM OF CONSIDERATION.  The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment.  Such consideration may consist entirely of:

                   (i)       cash or cash equivalent;

                   (ii)      check;

                   (iii)     recourse promissory note;


                                         -4-



                   (iv)      other Shares which (A) 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 (B) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

                   (v)       delivery of a properly executed exercise notice
together with such other documentation as the Administrator and the 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;

                   (vi)      such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws; or

                   (vii)     any combination of the foregoing methods of
payment.

    10.  EXERCISE OF OPTION.

         (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement.

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

              An Option shall be deemed exercised when the Company receives:
(i) written notice of exercise (in accordance with the Option Agreement) from
the person entitled to exercise the Option, and (ii) full payment for the Shares
with respect to which the Option is exercised.  Full payment may consist of any
consideration and method of payment authorized by the Administrator and
permitted by the Option Agreement and the Plan.  Shares issued upon exercise of
an Option shall be issued in the name of the Optionee or, if requested by the
Optionee, in the name of the Optionee and his or her spouse.  Until the stock
certificate evidencing such Shares is issued (as evidenced by the appropriate
entry on the books of the Company or of a duly authorized transfer agent of the
Company), no right to vote or 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 after the Option is exercised.  No adjustment will 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 12 of the
Plan.

              Exercising an Option in any manner shall decrease the number of
Shares thereafter 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.  Upon termination of an Optionee's
status as an Employee or Consultant (other than as a result of the Optionee's
death or Disability), the Optionee may exercise his or her Option, but only
within three (3) months or such other period of time as the


                                         -5-



Administrator shall specify from the date of such termination and, unless
determined otherwise by the Administrator, only to the extent that the Optionee
was entitled to exercise it at the date of such termination (and in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement).  To the extent that Optionee was not entitled to exercise an Option
at the date of such termination, and to the extent that the Optionee does not
exercise such Option (to the extent otherwise so entitled) within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.  For purposes of this Section 10(b), an
Employee's change of status from Employee to Consultant or from Consultant to
Employee shall not, unless specified otherwise by the Administrator, be
considered a termination of status as an Employee or Consultant.

         (c)  DISABILITY OF OPTIONEE.  Upon termination of an Optionee's status
as an Employee or Consultant as a result of the Optionee's Disability, the
Optionee may exercise his or her Option, but only within six (6) months or such
other time period as the Administrator shall specify from the date of such
termination, and, unless determined otherwise by the Administrator, only to the
extent that the Optionee was entitled to exercise it at the date of such
termination (and in no event later than the expiration of the term of such
Option as set forth in the Option Agreement).  To the extent that Optionee was
not entitled to exercise an Option at the date of such termination, and to the
extent that the Optionee does not exercise such Option (to the extent otherwise
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 an Optionee's death within
three (3) months of the termination of employment, the Optionee's estate or a
person who acquired the right to exercise the deceased Optionee's Option by
bequest or inheritance may exercise the Option, but only within six (6) months
or such other time period as the Administrator shall specify following the date
of death, and, unless determined otherwise by the Administrator, only to the
extent that the Optionee was entitled to exercise it at the date of death (but
in no event later than the expiration of the term of such Option as set forth in
the Option Agreement).  To the extent that Optionee was not entitled to exercise
an Option at the date of death, and to the extent that the Optionee's estate or
a person who acquired the right to exercise such Option does not exercise such
Option (to the extent otherwise so entitled) within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

    11.  NON-TRANSFERABILITY OF OPTIONS.  An Option 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.

    12.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION,OR TRANSFER IN
         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 which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have 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


                                         -6-



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;
provided, however, that 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 each
Optionee as soon as practicable prior to the effective date of such proposed
transaction.  To the extent it has not been previously exercised, an Option will
terminate immediately prior to the consummation of such proposed action.

         (c)  TRANSFER OF CONTROL.

              (i)  A "Transfer of Control" shall be deemed to have occurred in
the event any of the following occurs with respect to the Company:

                   (a)  a merger or consolidation in which the Company is not
the surviving corporation;

                   (b)  a merger or consolidation in which the Company is the
surviving corporation where the shareholders of the Company before such merger
or consolidation do not retain, directly or indirectly, at least a majority of
the beneficial interest in the voting stock of the Company after such merger or
consolidation;

                   (c)  the sale, exchange, or transfer of  all or
substantially all of the assets of the Company (other than a sale, exchange or
transfer to one (1) or more Subsidiaries);

                   (d)  the direct or indirect sale or exchange by the
shareholders of the Company of all or substantially all of the stock of the
Company where the shareholders of the Company before such sale or exchange do
not retain, directly or indirectly, at least a majority of the beneficial
interest in the voting stock of the Company after such sale or exchange.

              (ii) In the event of a Transfer of Control of  the Company, each
outstanding Option  will be assumed or an equivalent option substituted by the
successor corporation or a parent or Subsidiary of the successor corporation
(the "Successor Corporation").  In the event that an Option is not assumed or
substituted for, such Option shall terminate as of the date of the Transfer of
Control.  For the purposes of this paragraph, the Option  shall be considered
assumed if, following the Transfer of Control, the option confers the right to
purchase or receive, for each Share of Optioned Stock subject


                                         -7-



to the Option immediately prior to the Transfer of Control the consideration
(whether stock, cash, or other securities or property) received in the Transfer
of Control by holders of Common Stock for each Share held on the effective date
of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the Transfer
of Control was not solely common stock of the Successor Corporation, the
Administrator may, with the consent of the Successor Corporation, provide for
the consideration to be received upon the exercise of the Option for each Share
of Optioned Stock subject to the Option to be solely common stock of the
Successor Corporation equal in fair market value to the per share consideration
received by holders of Common Stock in the Transfer of Control.

    13.  DATE OF GRANT.  The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

    14.  WITHHOLDING TAXES.  In accordance with any applicable administrative
guidelines it establishes, the Administrator may allow a purchaser to pay the
amount of taxes required by law to be withheld as a result of a purchase of
Shares, by withholding from any payment of Common Stock due as a result of such
purchase, or by permitting the purchaser to deliver to the Company, Shares
having a Fair Market Value, as determined by the Administrator, equal to the
amount of such required withholding taxes.

    15.  AMENDMENT AND TERMINATION OF THE PLAN.

         (a)  AMENDMENT AND TERMINATION.  The Board may at any time amend,
alter, suspend or terminate the Plan.

         (b)  EFFECT OF AMENDMENT OR TERMINATION.  No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.

    16.  CONDITIONS UPON ISSUANCE OF SHARES.

         (a)  LEGAL COMPLIANCE.  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 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, Applicable Laws,
and the requirements of any stock exchange or quotation system upon which the
Shares may then be listed or quoted, and shall be further subject to the
approval of counsel for the Company with respect to such compliance.


                                         -8-



         (b)  INVESTMENT REPRESENTATIONS.  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.

    17.  LIABILITY OF COMPANY.  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.

    18.  RESERVATION OF SHARES.  The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.


                                         -9-
