EXHIBIT 99.1

                  AMENDED AND RESTATED 1996 STOCK OPTION PLAN

    1.  PURPOSE.  This Plan is intended to attract and retain highly qualified
individuals for positions of substantial responsibility, provide additional
incentives to Employees and Consultants of the Company and its Subsidiaries, and
promote the success of the Company's business.

    2.  DEFINED TERMS.  The meanings of defined terms (generally, capitalized
terms) in this Plan are provided in Section 22 ("Glossary").

    3.  STOCK SUBJECT TO PLAN.  Subject to Section 14, a maximum aggregate of
1,800,000 Shares may be issued under this Plan. The Shares may be authorized,
but unissued, or reacquired. If an Option expires or becomes unexercisable for
any reason, any unpurchased Optioned Shares shall be available for future
issuance under this Plan. Upon exercise of an Option, Shares retained because
other Shares are tendered in payment of the exercise price or to satisfy any
withholding tax obligations due to the exercise do not reduce the number of
Shares authorized for issuance.

    4.  ADMINISTRATION.

    (a)  IN GENERAL.  This Plan shall be administered by the Board or a
committee appointed by the Board. Once appointed, a committee shall serve until
otherwise directed by the Board. From time to time, the Board may increase the
size of the committee and appoint additional members, remove members (with or
without cause) and appoint new members in their stead, fill vacancies however
caused, and terminate the committee and thereafter directly administer this
Plan.

    (b)  OFFICERS AND DIRECTORS.  The Board may provide for administration of
this Plan with respect to Employees who are also officers or directors of the
Company by a Committee constituted so as to permit this Plan to comply as a
discretionary plan with Rule 16b-3 promulgated under the Exchange Act or any
successor thereto. A Committee appointed under this Section 4(b) may be separate
from any Committee appointed to administer this Plan with respect to Employees
who are neither officers nor directors.

    (b)  POWERS OF THE ADMINISTRATOR.  Subject to the provisions of this Plan
and in the case of a Committee, the specific duties delegated by the Board, the
Administrator shall have the authority, in its discretion:

        (i) to determine the Fair Market Value of the Common Stock;

        (ii) to grant Options to such Consultants and Employees as it selects
    from time to time;

       (iii) to determine the terms and conditions of each Option granted,
    including without limitation whether an Option is granted as an ISO or a
    NSO;

        (iv) to approve forms of agreement for use under this Plan;

        (v) to determine whether and under what circumstances to offer to buy
    out an Option for cash or Shares under Section 13;

        (vi) to modify grants of Options to participants who are foreign
    nationals or employed outside of the United States in order to recognize
    differences in local law, tax policies, or customs.

        (vi) to reduce the exercise price of any Option to the then-current Fair
    Market Value if the Fair Market Value of the Optioned Stock has declined
    since the date the Option was granted;

      (viii) to construe and interpret the terms of this Plan and Options
    granted pursuant to this Plan.

                                       11

    (c)  ADMINISTRATOR'S DECISIONS BINDING.  All decisions, determinations, and
interpretations of the Administrator shall be final and binding on all Optionees
and any other holders of Options.

    5.  ELIGIBILITY.

    (a)  NSOS/ISOS.  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 he or she is
otherwise eligible, be granted additional Options.

    (b)  LIMIT ON NUMBER OF SHARES.

        (i) No Employee shall be granted, in any fiscal year of the Company,
    Options to purchase more than 1,000,000 Shares, adjusted as described in
    Section 14.

        (ii) If an Option is canceled in the fiscal year of the Company in which
    it was granted (other than in connection with a transaction described in
    Section 14), the canceled Option will be counted against the limit set forth
    in subsection (i). For this purpose, if the exercise price of an Option is
    reduced, the transaction will be treated as a cancellation of the Option and
    the grant of a new Option.

    6.  TERM OF OPTION.  The term of each Option shall be determined by the
Administrator at the time of grant but shall not exceed ten years. In the case
of an ISO granted to an Optionee who, at the time of grant, owns stock
representing more than ten percent of the voting power of all classes of stock
of the Company or any Parent or Subsidiary, the Option term shall not exceed
five years.

    7.  DATE OF GRANT.  Unless otherwise determined by the Administrator, the
date of grant of an Option shall be the date on which the Administrator
completes the actions necessary to grant the Option. Notice of the grant shall
be given to the Optionee within a reasonable time after the date of the grant.

    8.  EXERCISE PRICE AND FORM OF CONSIDERATION.

    (a) The per-Share exercise price of an Option shall be determined by the
Administrator at the time of grant, but:

        (i) In the case of an ISO:

       (A) granted to an Employee who, at the time of the grant, owns stock
           representing more than ten percent of the voting power of all classes
           of stock of the Company or any Parent or Subsidiary, the per-Share
           exercise price shall be at least 110% of the Fair Market Value on the
           date of grant; or

       (B) granted to any other Employee, the per-Share exercise price shall be
           at least the Fair Market Value on the date of grant.

        (ii) In the case of a NSO granted to any person, the per-Share exercise
    price shall be no less than 85% of the Fair Market Value on the date of
    grant.

    (b)  FORM OF PAYMENT.  Payment for Shares upon exercise of an Option shall
be made in any lawful consideration approved by the Administrator and may,
without limitation, consist of (1) cash, (2) check, (3) promissory note,
(4) other Shares that have a total Fair Market Value on the date of payment
equal to the aggregate exercise price of the Shares as to which Option is
exercised, (5) delivery by a broker or brokerage firm approved by the
Administrator of a properly executed exercise notice together with payment of
the exercise price and such other documentation as the Administrator shall
require, or (6) any combination of the foregoing.

                                       12

    9.  EXERCISE.

    (a)  VESTING.  Each Option shall be exercisable at such times and under such
conditions as determined by the Administrator at the time of grant, and as are
otherwise permissible under the terms of this Plan, including without limitation
performance criteria with respect to the Company and/or the Optionee.

    (c)  MANNER OF EXERCISE; RIGHTS AS A SHAREHOLDER.  Unless otherwise allowed
by the Administrator, an Option shall be exercised by delivery of written notice
of exercise (in a form approved by the Administrator) to the Company in
accordance with the terms of the Option by the person entitled to exercise the
Option accompanied by (i) full payment for the number of whole Shares with
respect to which the Option is exercised, and (ii) payment (or provision for
payment) of withholding taxes pursuant to Subsection (f), below ("Notice"). The
Optionee shall be treated as a shareholder of the Company with respect to the
purchased Shares upon receipt of the Notice. An Option may not be exercised for
a fraction of a Share.

    (d)  OPTIONEE REPRESENTATIONS.  If Shares purchasable pursuant to the
exercise of an Option have not been registered under the Securities Act of 1933,
as amended, at the time the Option is exercised, the Optionee shall, if required
by the Administrator, as a condition to exercise of all or any portion of the
Option, deliver to the Company an investment representation statement in a form
approved by the Administrator.

    (e)  TERMINATION OF EMPLOYMENT OR CONSULTING RELATIONSHIP.  If an Optionee's
Continuous Service terminates the Optionee (or the Optionee's estate or heirs,
if termination of Continuous Service is due to death or the Optionee dies during
the post-termination exercise period of the Option) may exercise the Option,
(i) only within such period of time as is determined by the Administrator (but
no later than the expiration date determined by the Administrator at the time of
grant) and the Option shall terminate at the end of that period, and
(ii) unless otherwise determined by the Administrator, only to the extent that
the Optionee was entitled to exercise it at the date of termination. Unless
otherwise determined by the Administrator, the limits applicable under clause
(i) shall be: (A) 12 months if termination is due to total and permanent
disability, (B) six months if termination is due to death or disability that is
not total and permanent, and (C) three months if termination is for other
reasons.

    (f)  TAX WITHHOLDING.  The Company's obligation to deliver Shares upon
exercise of an Option is subject to payment (or provision for payment
satisfactory to the Administrator) by the Optionee of all federal, state, and
local income and employment taxes that the Administrator determines in its
discretion to be due as a result of the exercise of the Option or sale of the
Shares. The Administrator may allow the Optionee to elect at the time of
exercise of an Option to have withheld, from the Shares otherwise to be
delivered upon the exercise, Shares with an aggregate Fair Market Value equal to
a percentage (not more than 100%) designated by the Optionee of the withholding
taxes due upon exercise.

    10.  NON-EMPLOYEE DIRECTOR OPTION GRANTS.

    (a)  INITIAL GRANTS.  On the date of his or her first attendance at a duly
called meeting of the Board, each non-Employee Director elected or appointed to
the Board for the first time after October 21, 1999 office shall, automatically
be granted a NSO to purchase 75,000 Shares. Each non-Employee Director in office
on October 21, 1999 is granted on that date a NSO to purchase 75,000 Shares.

    (b)  ANNUAL GRANTS.  On the date of his or her first attendance at a duly
called meeting of the Board during a calendar year, each non-Employee Director
shall automatically be granted a NSO to purchase 10,000 Shares; PROVIDED,
HOWEVER, a non-Employee Director shall not receive a grant under this Section
10(b) in the same calendar year in which he or she receives a grant under
Section 10(a).

                                       13

    (c)  TERMS AND CONDITIONS.  The terms and conditions of each Option granted
pursuant to this Section 10 shall be as follows:

        (i) The term of the Option shall be ten years from the date of grant;

        (ii) The exercise price per Share shall be 100% of Fair Market Value on
    the date of grant;

       (iii) The Option shall be fully exercisable as of the date of grant;

        (iv) Except as provided below, the Option shall terminate on the date on
    which the Optionee's service as a Director terminates, PROVIDED, HOWEVER,
    that if such service terminates as a result of disability or death, the
    Optionee (or his or her estate or beneficiary) may exercise the NSO within
    12 months following the date of termination (but in no event after
    expiration of the option term); and

        (v) The other terms and conditions of the Option shall be consistent
    with the provisions of this Plan.

    11.  RULE 16B-3.  Except to the extent determined by the Administrator,
Options granted to persons subject to Section 16(b) of the Exchange Act shall
comply with Rule 16b-3 and shall contain such terms as may be required or
desirable to qualify Plan transactions for the maximum exemption from Section 16
of the Exchange Act.

    12.  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 or purchased
during the lifetime of the Optionee, only by the Optionee.

    13.  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 terms
and conditions that the Administrator establishes and communicates to the
Optionee at the time the offer is made.

    14.  CHANGES IN CAPITALIZATION OR CONTROL.

    (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by the
shareholders of the Company, the number of shares of Optioned Stock and the
number of Shares that have been authorized for issuance under this Plan but as
to which no Options have then been granted or that have been returned to this
Plan upon cancellation or expiration of an Option, as well as the price per
share of Optioned Stock, shall be proportionately adjusted for any change in the
number of issued Shares resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
change in the number of issued Shares effected without receipt of consideration
by the Company (not counting Shares issued upon conversion of convertible
securities of the Company as "effected without receipt of consideration"). Such
adjustment shall be made by the Board and 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 consequent adjustment shall be made with respect
to, the number or price of Shares subject to this Plan.

    (b)  DISSOLUTION OR LIQUIDATION.  If the Board approves a proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee at least 15 days before the proposed action. To the extent not
previously exercised, each Option shall then terminate immediately before
consummation of the proposed action.

    (c)  MERGER OR ASSET SALE.  If the Company merges with or into another
corporation, or sells all or substantially all of its assets, and if the
successor corporation or its Parent has not, by the 15th day before the
effective time of the merger or sale (the Effective Time"), agreed to assume
each outstanding Option, or to substitute an equivalent option, at the Effective
Time, then: (i) each outstanding Option shall be fully exercisable as to all of
its Optioned Shares until the Effective Time,

                                       14

(ii) the Administrator shall promptly so notify the Optionees, and (iii) each
Option shall terminate at the Effective Time.

    (d)  CHANGE IN CONTROL.  Unless the Administrator, in its discretion,
determines otherwise no less than 14 days before a Change in Control occurs, all
Options shall become fully exercisable beginning ten days before the Change in
Control. Notwithstanding the previous sentence, the Administrator may provide at
the time of grant of an Option that the Option shall become fully exercisable
upon, or a stated period before, a Change in Control even if the Administrator
makes an inconsistent determination pursuant to this Section 14(d)

    (e)  CERTAIN DISTRIBUTIONS.  If the Company makes a distribution to its
shareholders of securities of any other entity or other assets (other than
dividends payable in cash or stock of the Company) without receipt of
consideration, the Administrator may, in its discretion, appropriately adjust
the exercise price of each outstanding Option to reflect the distribution.

    15.  AMENDMENTS.  The Board may at any time amend, alter, suspend, or
discontinue this Plan, but no such action shall impair the rights of any
Optionee under any then-outstanding Option without his or her prior written
consent.

    16.  SECURITIES REGULATION REQUIREMENTS.

    (a)  COMPLIANCE WITH RULE; BUY-OUT OFFER.  In general, Shares shall not be
issued pursuant to the exercise of an Option unless the exercise of the Option
and issuance of the Shares 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, the requirements
of any stock exchange upon which the Shares may then be listed, and the
requirements of any regulatory body having jurisdiction. If when the Company
receives notice of exercise of an Option, the Administrator believes in its
discretion that the period before Shares may be issued will exceed 21 days, the
Administrator shall (unless it determines that such an offer is itself prevented
by the rules described in the preceding sentence) make an offer pursuant to
Section 13 to buy out the portion of the Option corresponding to the number of
Shares whose issuance is thus prevented. The buy-out offer shall be valid for no
less than 21 days.

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

    17.  WRITTEN OPTION AGREEMENTS.  Options shall be evidenced by written
agreements in a form the Administrator approves from time to time. The written
agreement shall designate the Option as either an Incentive Stock Option or a
Nonstatutory Stock Option. Delay in executing a written agreement shall not
affect the date of grant of an Option; however, an Option may not be exercised
until a written agreement has been executed by the Company and the Optionee.

    18.  SHAREHOLDER APPROVAL.  This Plan is subject to approval by the
shareholders of the Company within 12 months after the Board adopts this Plan.
Shareholder approval shall be obtained in the degree and manner required under
applicable state and federal law and the rules of any stock exchange upon which
the Common Stock is listed.

    19.  INFORMATION TO OPTIONEES.  The Company shall provide to each Optionee
copies of financial statements at least annually, at the same time and in the
same form as it furnishes such information to its shareholders. The Company
shall not be required to provide such statements to key employees whose duties
assure their access to equivalent information.

                                       15

    20.  TERM OF PLAN.  This Plan shall become effective upon the earlier to
occur of adoption by the Board of Directors or approval by the shareholders of
the Company as described in Section 18. It shall continue in effect for a term
of ten years unless sooner terminated under Section 15.

    21.  NO RIGHT TO EMPLOYMENT.  This Plan shall not confer upon any Optionee
any right with respect to continuation of employment or consulting relationship
with the Company, nor shall it interfere in any way with such Optionee's right
or the Company's right to terminate his or her employment or consulting
relationship at any time, with or without cause.
