                                PROXY STATEMENT
                      FOR SPECIAL MEETING OF STOCKHOLDERS

                                  To Be Held
                               October 20, 1999

                INFORMATION CONCERNING SOLICITATION AND VOTING

General

  The enclosed proxy is solicited on behalf of the Board of Directors of
Siebel Systems, Inc., a Delaware corporation (the "Company"), for use at the
Special Meeting of Stockholders to be held on Wednesday, October 20, 1999 at
11:00 a.m. local time (the "Special Meeting"), or at any adjournment or
postponement thereof, for the purposes set forth herein and in the
accompanying Notice of Special Meeting. The Special Meeting will be held at
the Company's principal executive offices located at 1855 South Grant Street,
San Mateo, California 94402. The Company intends to mail this proxy statement
and accompanying proxy card on or about September 16, 1999 to all stockholders
entitled to vote at the Special Meeting.

Solicitation

  The Company will bear the entire cost of solicitation of proxies, including
preparation, assembly, printing and mailing of this proxy statement, the proxy
and any additional information furnished to stockholders. Copies of
solicitation materials will be furnished to banks, brokerage houses,
fiduciaries and custodians holding in their names shares of Common Stock
beneficially owned by others to forward to such beneficial owners. The Company
may reimburse persons representing beneficial owners of Common Stock for their
costs of forwarding solicitation materials to such beneficial owners. Original
solicitation of proxies by mail may be supplemented by telephone, telegram or
personal solicitation by directors, officers or other regular employees of the
Company or, at the Company's request. No additional compensation will be paid
to directors, officers or other regular employees for such services, but a
third-party proxy solicitor to be determined by the Company will be paid its
customary fee, estimated to be about $7,000, if it renders solicitation
services.

Voting Rights and Outstanding Shares

  Only holders of record of Common Stock at the close of business on September
3, 1999 (the "Record Date") will be entitled to notice of and to vote at the
Special Meeting. On the Record Date, the Company had 93,156,018 shares of
Common Stock outstanding and entitled to vote.

  Each holder of record of Common Stock on such date will be entitled to one
vote for each share held on all matters to be voted upon at the Special
Meeting.

  All votes will be tabulated by the inspector of election appointed for the
meeting, who will separately tabulate affirmative and negative votes,
abstentions and broker non-votes. The affirmative vote of a majority of the
outstanding shares of Common Stock is required to approve Proposal 1 to be
voted on at the Special Meeting. For purposes of Proposal 1, abstentions and
broker non-votes will have the same effect as negative votes. The affirmative
vote of the holders of a majority of the shares present in person or
represented by proxy and entitled to vote will be required to approve Proposal
2 to be voted on at the Special Meeting. For purposes of Proposal 2,
abstentions will be counted towards the tabulation of votes cast on proposals
presented to the stockholders and will have the same effect as negative votes.
Broker non-votes will be counted towards a quorum, but will not be counted for
any purpose in determining whether a matter has been approved.

                                       1
<PAGE>

Revocability of Proxies

  Any person giving a proxy pursuant to this solicitation has the power to
revoke it at any time before it is voted. It may be revoked by filing with the
Secretary of the Company at the Company's principal executive office, 1855
South Grant Street, San Mateo, California 94402, a written notice of
revocation or a duly executed proxy bearing a later date, or it may be revoked
by attending the meeting and voting in person. Attendance at the meeting will
not, by itself, revoke a proxy.

Stockholder Proposals

  Pursuant to the Company's bylaws, a stockholder proposal or a nomination for
director that is not to be included in such proxy statement and proxy at the
Company's 2000 annual meeting of stockholders must provide specified
information to the Company between January 27, 2000 and February 26, 2000
(unless such matters are included in the Company's proxy statement pursuant to
Rule 14a-8 under the Securities Exchange Act of 1934, as amended).

                                  PROPOSAL 1

      APPROVAL OF INCREASE IN NUMBER OF AUTHORIZED SHARES OF COMMON STOCK

  The Board of Directors has adopted, subject to stockholder approval, an
amendment to the Company's Amended and Restated Certificate of Incorporation
to increase the Company's authorized number of shares of Common Stock from
300,000,000 shares to 800,000,000 shares.

  The additional Common Stock to be authorized by adoption of the amendment
would have rights identical to the currently outstanding Common Stock of the
Company. Adoption of the proposed amendment and issuance of the Common Stock
would not affect the rights of the holders of currently outstanding Common
Stock of the Company, except for effects incidental to increasing the number
of shares of the Company's Common Stock outstanding, such as dilution of the
earnings per share and voting rights of current holders of Common Stock. If
the amendment is adopted, it will become effective upon filing of a
Certificate of Amendment of the Company's Amended and Restated Certificate of
Incorporation with the Secretary of State of the State of Delaware, a form of
which is attached hereto as Exhibit A.

  In addition to the 93,156,018 shares of Common Stock outstanding at
September 3, 1999, as of September 9, 1999, the Board had reserved (i)
28,701,008 shares for issuance upon exercise of outstanding options granted
and heretofore unexercised under the Company's 1996 Equity Incentive Plan;
(ii) 1,750,291 shares for issuance under the 1996 Employee Stock Purchase
Plan; and (iii) 12,082,140 shares of issuance upon exercise of options granted
under the 1998 Equity Incentive Plan.

  The Board desires to have additional authorized shares for future business
and financial purposes. The additional shares may be used, without further
stockholder approval, for various purposes including, without limitation,
stock dividends to existing stockholders, raising capital, providing equity
incentives to employees, officers or directors, establishing certain strategic
relationships with other companies and expanding the Company's business or
product lines through certain acquisitions of other businesses or products.

  The Board has approved, subject to stockholder approval of this Proposal 1,
a 100% stock dividend to be issued on all outstanding shares of the Company's
Common Stock. The objective of the stock dividend would be to proportionately
lower the market price of the Company's Common Stock. Such lower price is
expected to increase the liquidity and broaden the marketability of the
Company's Common Stock. In addition, the stock dividend would enable the
Company to provide its employees and consultants with more attractive equity-
based incentive packages, and therefore, will allow the Company to more easily
attract and retain qualified employees and consultants. The Board may decide,
in the best interests of the Company and due to market conditions or
otherwise, not to reflect the stock dividend. Therefore, no assurances can be
given that the Board will determine to effect any stock dividend even if the
foregoing Proposal 1 is adopted. Other than such possible dividend, the
Company has no plans, arrangements or understandings regarding the additional
shares that would be authorized pursuant to this Proposal 1.

                                       2
<PAGE>

  The additional shares of Common Stock that would become available for
issuance if this proposal were adopted could also be used by the Company to
oppose a hostile takeover attempt or delay or prevent changes in control or
management of the Company. For example, without further stockholder approval,
the Board could (i) adopt a "poison pill" which would, under certain
circumstances related to an acquisition not approved by the Board of
Directors, give certain holders the right to acquire additional shares of
Common Stock at a low price, or (ii) sell shares of Common Stock in a private
transaction to purchasers who would oppose a takeover or favor the current
Board. Although this proposal to increase the authorized Common Stock has been
prompted by business and financial considerations and not by the threat of any
known or threatened hostile takeover attempt, stockholders should be aware
that approval of this proposal could facilitate future efforts by the Company
to deter or prevent changes in control of the Company, including transactions
in which the stockholders might otherwise receive a premium for their shares
over then current market prices.

  The affirmative vote of the holders of a majority of the outstanding shares
of the Common Stock will be required to approve this amendment to the
Company's Restated Certificate of Incorporation. As a result, abstentions and
broker non-votes will have the same effect as negative votes.

                       The Board Of Directors Recommends
                    That Stockholders Vote FOR Proposal 1.

                                  PROPOSAL 2

              APPROVAL OF AMENDMENT TO 1996 EQUITY INCENTIVE PLAN

  In December 1994, the Board of Directors adopted, and the stockholders
subsequently approved, the Company's 1994 Stock Option Plan. In February 1996,
the Board of Directors adopted, and the stockholders subsequently approved,
the Company's 1996 Supplemental Stock Option Plan. On May 14, 1996, the Board
of Directors amended and restated both of the above plans in the form of the
1996 Equity Incentive Plan (the "1996 Plan"), which was subsequently approved
by the stockholders of the Company. The 1996 Plan was amended and restated by
the Board of Directors to increase the number of shares authorized for
issuance under the 1996 Plan on October 14, 1996, which amendment was
subsequently approved by the stockholders. On January 10, 1997, the 1996 Plan
was amended to comply with changes in securities laws. On August 23, 1999, the
Board of Directors approved the amendment increasing the number of shares
authorized for issuance under the 1996 Plan discussed below and the
solicitation of stockholders to approve such amendment.

  At September 9, 1999, options (net of cancelled or expired options) covering
an aggregate of 39,260,724 shares of the Company's Common Stock had been
granted under the 1996 Plan, and only 739,276 shares (plus any shares that
might in the future be returned to the plans as a result of cancellations or
expiration of options) remained available for future grant under the 1996
Plan. Since the end of the last fiscal year, under the 1996 Plan, the Company
granted to all current executive officers as a group options to purchase
2,000,000 shares at exercise prices of $19.625 to $38.44 per share, and the
Company granted to all employees as a group (excluding executive officers)
options to purchase 6,542,500 shares at exercise prices of $34.25 to $60.31
per share. Since the end of the last fiscal year, no options have been granted
to directors who are not officers.

  Stockholders are requested in this Proposal 2 to approve an amendment to the
1996 Plan to increase the number of shares authorized for issuance under the
1996 Plan by 15,000,000 shares, from a total of 40,000,000 shares to
55,000,000 shares. The purpose of this amendment is to ensure that the Company
can continue to grant stock options to employees and consultants at levels
determined appropriate by the Board and Compensation Committee. The Company
believes that its ability to continue to provide employees with attractive
equity-based incentives is critical in allowing it to attract and retain
qualified individuals. The Company believes the grant of stock options
encourages employees to build long-term stockholder value. The affirmative
vote of the holders of a majority of the shares present in person or
represented by proxy and entitled to vote at the meeting will be

                                       3
<PAGE>

required to approve the increase to the 1996 Plan. Abstentions will be counted
toward the tabulation of votes cast on proposals presented to the stockholders
and will have the same effect as negative votes. Broker non-votes are counted
towards a quorum, but are not counted for any purpose in determining whether
this matter has been approved.

                       The Board Of Directors Recommends
                    That Stockholders Vote FOR Proposal 2.

Summary of Terms of the 1996 Plan

General

  The 1996 Plan provides for the grant of (i) both incentive and nonstatutory
stock options, (ii) stock bonuses, (iii) rights to purchase restricted stock,
and (iv) stock appreciation rights (collectively, "Stock Awards"). Incentive
stock options granted under the 1996 Plan are intended to qualify as
"incentive stock options" within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"). Nonstatutory stock options
granted under the 1996 Plan are intended not to qualify as incentive stock
options under the Code. See "Federal Income Tax Information" for a discussion
of the tax treatment of incentive and nonstatutory stock options. A complete
copy of the 1996 Plan, as amended, is attached hereto as Exhibit B.

Purpose

  The 1996 Plan was adopted to (i) provide a means by which selected
directors, officers and employees of and consultants to the Company and its
affiliates could be given an opportunity to benefit from increases in the
value of the stock of the Company, (ii) assist in retaining the services of
employees holding key positions, to secure and retain the services of persons
capable of filling such positions and (iii) provide incentives for such
persons to exert maximum efforts for the success of the Company. All of the
Company's 2,145 employees (as of June 30, 1999) and all of the Company's
directors and consultants are eligible to participate in the 1996 Plan,
however, only employees of the Company may be granted incentive stock options
or stock appreciation rights pursuant to the Plan.

Administration

  The 1996 Plan is administered by the Board of Directors of the Company. The
Board has the power to construe and interpret the 1996 Plan and, subject to
the provisions of the 1996 Plan, to determine the persons to whom and the
dates on which Stock Awards will be granted; whether a Stock Award will be an
incentive stock option, a nonstatutory stock option, a stock bonus, a right to
purchase restricted stock, a stock appreciation right or a combination of the
foregoing; the provisions of each Stock Award granted (which need not be
identical), including the time or times when a person shall be permitted to
receive stock pursuant to a Stock Award; whether a person shall be permitted
to receive stock upon exercise of an independent stock appreciation right; and
the number of shares with respect to which a Stock Award shall be granted to
each such person. The Board of Directors is authorized to delegate
administration of the 1996 Plan to a committee composed of not fewer than two
members of the Board. In the discretion of the Board, a Committee may consist
solely of two or more Outside Directors in accordance with Code Section 162(m)
or solely of tow or more Non-Employee Directors in accordance with Rule 16(b)-
3. The Board has delegated administration of the 1996 Plan to the Compensation
Committee of the Board. As used herein with respect to the 1996 Plan, the
"Board" refers to the Compensation Committee as well as to the Board of
Directors itself.


Eligibility

  Incentive stock options and stock appreciation rights related to incentive
stock options may be granted under the 1996 Plan only to employees (including
officers) of the Company and its affiliates. Employees (including

                                       4
<PAGE>

officers), directors and consultants are eligible to receive Stock Awards
other than incentive stock options and such stock appreciation rights under
the 1996 Plan.

  No incentive stock option may be granted under the 1996 Plan to any person
who, at the time of the grant, owns (or is deemed to own) stock possessing
more than 10% of the total combined voting power of the Company or any
affiliate of the Company, unless the option exercise price is at least 110% of
the fair market value of the stock subject to the option on the date of grant,
and the term of the option does not exceed five years from the date of grant.
For incentive stock options granted under the 1996 Plan, the aggregate fair
market value, determined at the time of grant, of the shares of Common Stock
with respect to which such options are exercisable for the first time by an
optionee during any calendar year (under all such plans of the Company and its
affiliates) may not exceed $100,000.

  The Company has included in the 1996 Plan a per-employee, per-calendar year
limitation equal to 2,000,000 shares of Common Stock on options and stock
appreciation rights granted under the 1996 Plan. The purpose of adding this
limitation is generally to permit the Company to be able to deduct for tax
purposes the compensation attributable to the exercise of options granted
under the 1996 Plan.

Stock Subject to the 1996 Plan

  If any Stock Award granted under the 1996 Plan expires or otherwise
terminates, in full or in part, without being exercised in full, the Common
Stock not acquired pursuant to such Stock Award again becomes available for
issuance under the 1996 Plan.

Terms of Options

  The following is a description of the permissible terms of options under the
1996 Plan. Individual option grants may be more restrictive as to any or all
of the permissible terms described below.

  Exercise Price; Payment. The exercise price of incentive stock options under
the 1996 Plan may not be less than the fair market value of the Common Stock
subject to the option on the date of the option grant, and in some cases (see
"Eligibility" above), may not be less than 110% of such fair market value. The
exercise price of nonstatutory options under the 1996 Plan is determined by
the Board. At September 3, 1999, the closing price of the Company's Common
Stock as reported on the Nasdaq National Market System was $74.44 per share.

  In the event of a decline in the value of the Company's Common Stock, the
Board has the authority to offer employees the opportunity to replace
outstanding higher priced options, whether incentive or nonstatutory, with new
lower priced options. To the extent required by Section 162(m), an option
repriced under the 1996 Plan is deemed to be cancelled and a new option
granted. Both the option deemed to be cancelled and the new option deemed to
be granted will be counted against the 2,000,000 share limitation.

  The exercise price of options granted under the 1996 Plan must be paid
either: (a) in cash at the time the option is exercised; or (b) by delivery of
other Common Stock of the Company or (c) in the discretion of the Board,
pursuant to a deferred payment arrangement or in any other form of legal
consideration.

  Option Exercise. Options granted under the 1996 Plan may become exercisable
("vest") in cumulative increments as determined by the Board. Shares covered
by currently outstanding options under the 1996 Plan typically vest at the
rate of 20% of the shares subject to the option on the first anniversary of
the date of hire and 5% of such shares at the end of each quarter thereafter
during the optionee's employment or provision of services as a consultant.
Shares covered by options granted in the future under the 1996 Plan may be
subject to different vesting terms. The Board has the power to accelerate the
time during which an option may be exercised. In addition, options granted
under the 1996 Plan may permit exercise prior to vesting, but in such event
the optionee may be required to enter into an early exercise stock purchase
agreement that allows the Company to repurchase shares not yet vested at their
exercise price should the optionee leave the service of the Company before
vesting.

                                       5
<PAGE>

To the extent provided by the terms of an option, and in the discretion of the
Board, an optionee may satisfy any federal, state or local tax withholding
obligation relating to the exercise of such option by a cash payment upon
exercise, by authorizing the Company to withhold a portion of the stock
otherwise issuable to the optionee, by delivering already-owned stock of the
Company or by a combination of these means.

  Term. The maximum term of options under the 1996 Plan is 10 years, except
that in certain cases (see "Eligibility") the maximum term is five or seven
years. Options under the 1996 Plan terminate three months after termination of
the optionee's employment or relationship as a consultant or director of the
Company or any affiliate of the Company, unless (a) such termination is due to
such person's permanent and total disability (as defined in the Code), in
which case the option may, but need not, provide that it may be exercised at
any time within one year of such termination; (b) the optionee dies while
employed by or serving as a consultant or director of the Company or any
affiliate of the Company, or within a period specified by the option after
termination of such relationship, in which case the option may be exercised
(to the extent the option was exercisable at the time of the optionee's death)
within the period ending on the earlier of twelve (12) months of the
optionee's death or the expiration of the term of the option by the person or
persons to whom the rights to such option pass by will or by the laws of
descent and distribution; or (c) the option by its terms specifically provides
otherwise. The option term may also be extended in the event that exercise of
the option within these periods is prohibited for specified reasons.

Terms of Stock Bonuses and Purchases of Restricted Stock

  The following is a description of the permissible terms of stock bonuses and
restricted stock purchase agreements under the 1996 Plan. The terms and
conditions of stock bonus or restricted stock purchase agreements may change
from time to time, and the terms and conditions of separate agreements need
not be identical, but each stock bonus or restricted stock purchase agreement
includes the substance of each of the following provisions as appropriate:

    Purchase Price. The purchase price under each restricted stock purchase
  agreement is such amount as the Board may determine and designate in such
  agreement but in no event may the purchase price be less than eighty-five
  percent (85%) of the stock's fair market value on the date such award is
  made. Notwithstanding the foregoing, the Board may determine that eligible
  participants in the 1996 Plan may be awarded stock pursuant to a stock
  bonus agreement in consideration for past services actually rendered to the
  Company for its benefit.

    Consideration. The purchase price of stock acquired pursuant to a stock
  purchase agreement must be paid either: (i) in cash at the time of
  purchase; (ii) at the discretion of the Board or the Committee, according
  to a deferred payment or other arrangement with the person to whom the
  stock is sold; or (iii) in any other form of legal consideration that may
  be acceptable to the Board or the Committee in its discretion.
  Notwithstanding the foregoing, the Board may award stock pursuant to a
  stock bonus agreement in consideration for past services actually rendered
  to the Company or for its benefit.

    Vesting. Shares of stock sold or awarded under the Plan may, but need
  not, be subject to a repurchase option in favor of the Company in
  accordance with a vesting schedule to be determined by the Board.

    Termination of Employment or Relationship as a Director or Consultant. In
  the event a participant's continuous status as an employee, director or
  consultant terminates, the Company may repurchase or otherwise re-acquire
  any or all of the shares of stock held by that person which have not vested
  as of the date of termination under the terms of the stock bonus or
  restricted stock purchase agreement between the Company and such person.

                                       6
<PAGE>

Stock Appreciation Rights

  The three types of Stock Appreciation Rights that are authorized for
issuance under the 1996 Plan are as follows:

    Tandem Stock Appreciation Rights. Tandem stock appreciation rights may be
  granted appurtenant to an option, and are generally subject to the same
  terms and conditions applicable to the particular option grant to which it
  pertains. Tandem stock appreciation rights require the holder to elect
  between the exercise of the underlying option for shares of stock and the
  surrender, in whole or in part, of such option for an appreciation
  distribution. The appreciation distribution payable on the exercised tandem
  right is in cash (or, if so provided, in an equivalent number of shares of
  stock based on fair market value on the date of the option surrender) in an
  amount up to the excess of (A) the fair market value (on the date of the
  option surrender) of the number of shares of stock covered by that portion
  of the surrendered option in which the optionee is vested over (B) the
  aggregate exercise price payable for such vested shares.

    Concurrent Stock Appreciation Rights. Concurrent rights may be granted
  appurtenant to an option and may apply to all or any portion of the shares
  of stock subject to the underlying option and are generally subject to the
  same terms and conditions applicable to the particular option grant to
  which it pertains. A concurrent right is exercised automatically at the
  same time the underlying option is exercised with respect to the particular
  shares of stock to which the concurrent right pertains. The appreciation
  distribution payable on an exercised concurrent right is in cash (or, if so
  provided, in an equivalent number of shares of stock based on fair market
  value on the date of the exercise of the concurrent right) in an amount
  equal to such portion as shall be determined by the Board at the time of
  the grant of the excess of (A) the aggregate fair market value (on the date
  of the exercise of the concurrent right) of the vested shares of stock
  purchased under the underlying option which have concurrent rights
  appurtenant to them over (B) the aggregate exercise price paid for such
  shares.

    Independent Stock Appreciation Rights. Independent Rights may be granted
  independently of any option and are generally subject to the same terms and
  conditions applicable to nonstatutory stock options. The appreciation
  distribution payable on an exercised independent right may not be greater
  than an amount equal to the excess of (A) the aggregate fair market value
  (on the date of the exercise of the independent right) of a number of
  shares of Company stock equal to the number of share equivalents in which
  the holder is vested under such independent right, and with respect to
  which the holder is exercising the independent right on such date, over (B)
  the aggregate fair market value (on the date of the grant of the
  independent right) of such number of shares of Company stock. The
  appreciation distribution payable on the exercised independent right is in
  cash or, if so provided, in an equivalent number of shares of stock based
  on fair market value on the date of the exercise of the independent right.

Adjustment Provisions

  If there is any change in the stock subject to the 1996 Plan or subject to
any Stock Award granted under the 1996 Plan (through merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange
of shares, change in corporate structure or transaction not involving the
receipt of consideration by the Company), the 1996 Plan and Stock Award
outstanding thereunder will be appropriately adjusted as to the class and the
maximum number of shares subject to such plan, the maximum number of shares
which may be granted to an employee during a calendar year, and the class,
number of shares and price per share of stock subject to such outstanding
Stock Awards.

Effect of Certain Corporate Events

  The 1996 Plan provides that, in the event of a dissolution, liquidation or
sale of substantially all of the assets of the Company, a specified type of
merger or other corporate reorganization, to the extent permitted by law, any
surviving corporation will be required to either assume Stock Awards
outstanding under the 1996 Plan or substitute similar Stock Awards for those
outstanding under such plan, or such outstanding Stock Awards will

                                       7
<PAGE>

continue in full force and effect. In the event that any surviving corporation
declines to assume or continue Stock Awards outstanding under the 1996 Plan,
or to substitute similar Stock Awards, then with respect to Stock Awards held
by persons then performing services as employees, directors or consultants,
the time during which such Stock Awards may be exercised will be accelerated
and the Stock Awards terminated if not exercised prior to such corporate
event. The acceleration of a Stock Award in the event of an acquisition or
similar corporate event may be viewed as an anti-takeover provision, which may
have the effect of discouraging a proposal to acquire or otherwise obtain
control of the Company.

Duration, Amendment and Termination

  The Board may suspend or terminate the 1996 Plan without stockholder
approval or ratification at any time or from time to time. Unless sooner
terminated, the 1996 Plan will terminate on May 14, 2006.

  The Board may also amend the 1996 Plan at any time or from time to time.
However, no amendment will be effective unless approved by the stockholders of
the Company within twelve months before or after its adoption by the Board if
the amendment would: (a) modify the requirements as to eligibility for
participation (to the extent such modification requires stockholder approval
in order for the Plan to satisfy Section 422 of the Code, if applicable, or
Rule 16b-3 ("Rule 16b-3") of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"); (b) increase the number of shares reserved for issuance
upon exercise of options; or (c) change any other provision of the Plan in any
other way if such modification requires stockholder approval in order to
comply with Rule 16b-3 or satisfy the requirements of Section 422 of the Code.
The Board may submit any other amendment to the 1996 Plan for stockholder
approval, including, but not limited to, amendments intended to satisfy the
requirements of Section 162(m) of the Code regarding the exclusion of
performance-based compensation from the limitation on the deductibility of
compensation paid to certain employees.

Restrictions on Transfer

  Under the 1996 Plan, an incentive stock option may not be transferred by the
optionee otherwise than by will or by the laws of descent and distribution and
during the lifetime of the optionee, may be exercised only by the optionee. A
nonstatutory stock option may not be transferred except by will or by the laws
of descent and distribution or pursuant to a "qualified domestic relations
order." In any case, the optionee may designate in writing a third party who
may exercise the option in the event of the optionee's death. In addition,
shares subject to repurchase by the Company under an early exercise stock
purchase agreement may be subject to restrictions on transfer which the Board
deems appropriate. No rights under a stock bonus or restricted stock purchase
agreement shall be transferable except by will or the laws of descent and
distribution or pursuant to a qualified domestic relations order satisfying
the requirements of Rule 16b-3 and any administrative interpretations or
pronouncements thereunder, so long as stock awarded under such agreement
remains subject to the terms of the agreement.

Federal Income Tax Information

  Incentive Stock Options. Incentive stock options under the 1996 Plan are
intended to be eligible for the favorable federal income tax treatment
accorded "incentive stock options" under the Code.

  There generally are no federal income tax consequences to the optionee or
the Company by reason of the grant or exercise of an incentive stock option.
However, the exercise of an incentive stock option may increase the optionee's
alternative minimum tax liability, if any.

  If an optionee holds stock acquired through exercise of an incentive stock
option for at least two years from the date on which the option is granted and
at least one year from the date on which the shares are transferred to the
optionee upon exercise of the option, any gain or loss on a disposition of
such stock will be long-term capital gain or loss. Generally, if the optionee
disposes of the stock before the expiration of either of these holding

                                       8
<PAGE>

periods (a "disqualifying disposition"), at the time of disposition, the
optionee will realize taxable ordinary income equal to the lesser of (a) the
excess of the stock's fair market value on the date of exercise over the
exercise price, or (b) the optionee's actual gain, if any, on the purchase and
sale. The optionee's additional gain, or any loss, upon the disqualifying
disposition will be a capital gain or loss, which will be long-term or short-
term depending on whether the stock was held for more than one year. Long-term
capital gains currently are generally subject to lower tax rates than ordinary
income. The maximum capital gains rate for federal income tax purposes is
currently 20% while the maximum ordinary income rate is effectively 39.6% at
the present time. Slightly different rules may apply to optionees who acquire
stock subject to certain repurchase options.

  To the extent the optionee recognizes ordinary income by reason of a
disqualifying disposition, the Company will generally be entitled (subject to
the requirement of reasonableness, the provisions of Section 162(m) of the
Code and the satisfaction of a tax reporting obligation) to a corresponding
business expense deduction in the tax year in which the disqualifying
disposition occurs.

  Nonstatutory Stock Options. Nonstatutory stock options granted under the
1996 Plan generally have the following federal income tax consequences:

    There are no tax consequences to the optionee or the Company by reason of
  the grant of a nonstatutory stock option. Upon exercise of a nonstatutory
  stock option, the optionee normally will recognize taxable ordinary income
  equal to the excess of the stock's fair market value on the date of
  exercise over the option exercise price. Generally, with respect to
  employees, the Company is required to withhold from regular wages or
  supplemental wage payments an amount based on the ordinary income
  recognized. Subject to the requirement of reasonableness, the provisions of
  Section 162(m) of the Code and the satisfaction of a tax reporting
  obligation, the Company will generally be entitled to a business expense
  deduction equal to the taxable ordinary income realized by the optionee.
  Upon disposition of the stock, the optionee will recognize a capital gain
  or loss equal to the difference between the selling price and the sum of
  the amount paid for such stock plus any amount recognized as ordinary
  income upon exercise of the option. Such gain or loss will be long or
  short-term depending on whether the stock was held for more than one year.
  Slightly different rules may apply to optionees who acquire stock subject
  to certain repurchase options.

  Restricted Stock and Stock Bonuses. Restricted stock and stock bonuses
granted under the 1996 Plan generally have the following federal income tax
consequences:

    Upon acquisition of stock under a restricted stock or stock bonus award,
  the recipient normally will recognize taxable ordinary income equal to the
  excess of the stock's fair market value over the purchase price, if any.
  However, to the extent the stock is subject to certain types of vesting
  restrictions, the taxable event will be delayed until the vesting
  restrictions lapse unless the recipient elects to be taxed on receipt of
  the stock. Generally, with respect to employees, the Company is required to
  withhold from regular wages or supplemental wage payments an amount based
  on the ordinary income recognized. Subject to the requirement of
  reasonableness, Section 162(m) of the Code and the satisfaction of a tax
  reporting obligation, the Company will generally be entitled to a business
  expense deduction equal to the taxable ordinary income realized by the
  recipient. Upon disposition of the stock, the recipient will recognize a
  capital gain or loss equal to the difference between the selling price and
  the sum of the amount paid for such stock, if any, plus any amount
  recognized as ordinary income upon acquisition (or vesting) of the stock.
  Such gain or loss will be long or short-term depending on whether the stock
  was held for more than one year from the date ordinary income is measured.
  Slightly different rules may apply to persons who acquire stock subject to
  forfeiture.

  Stock Appreciation Rights. No taxable income is realized upon the receipt of
a stock appreciation right, but upon exercise of the stock appreciation right
the fair market value of the shares (or cash in lieu of shares) received must
be treated as compensation taxable as ordinary income to the recipient in the
year of such exercise. Generally, with respect to employees, the Company is
required to withhold from the payment made on exercise of the stock
appreciation right or from regular wages or supplemental wage payments an
amount based on the

                                       9
<PAGE>

ordinary income recognized. Subject to the requirement of reasonableness,
Section 162(m) of the Code and the satisfaction of a reporting obligation, the
Company will be entitled to a business expense deduction equal to the taxable
ordinary income recognized by the recipient.

  Potential Limitation on Company Deductions. As part of the Omnibus Budget
Reconciliation Act of 1993, the U.S. Congress amended the Code to add Section
162(m) which denies a deduction to any publicly held corporation for
compensation paid to certain employees in a taxable year to the extent that
compensation exceeds $1 million for a covered employee. It is possible that
compensation attributable to awards under the 1996 Plan, when combined with
all other types of compensation received by a covered employee from the
Company, may cause this limitation to be exceeded in any particular year.

  Certain kinds of compensation, including qualified "performance-based
compensation," are disregarded for purposes of the deduction limitation. In
accordance with applicable Treasury regulations issued under Section 162(m) of
the Code, compensation attributable to stock options and stock appreciation
rights will qualify as performance-based compensation, provided that: (i) the
stock award plan contains a per-employee limitation on the number of shares
for which stock options and stock appreciation rights may be granted during a
specified period; (ii) the per-employee limitation is approved by the
stockholders; (iii) the award is granted by a compensation committee comprised
solely of "outside directors"; and (iv) the exercise price of the award is no
less than the fair market value of the stock on the date of grant.
Compensation attributable to restricted stock will qualify as performance-
based compensation, provided that: (i) the award is granted by a compensation
committee comprised solely of "outside directors"; and (ii) the purchase price
of the award is no less than the fair market value of the stock on the date of
grant. Stock bonuses qualify as performance-based compensation under these
Treasury regulations only if: (i) the award is granted by a compensation
committee comprised solely of "outside directors;" (ii) the award is granted
(or exercisable) only upon the achievement of an objective performance goal
established in writing by the compensation committee while the outcome is
substantially uncertain; (iii) the compensation committee certifies in writing
prior to the granting (or exercisability) of the award that the performance
goal has been satisfied; and (iv) prior to the granting (or exercisability) of
the award, stockholders have approved the material terms of the award
(including the class of employees eligible for such award, the business
criteria on which the performance goal is based, and the maximum amount (or
formula used to calculate the amount) payable upon attainment of the
performance goal).

                       ADDITIONAL EQUITY INCENTIVE PLANS

I. 1998 Equity Incentive Plan

  In October 1998, the Board of Directors adopted the 1998 Equity Incentive
Plan (the "1998 Plan") to offer nonstatutory stock options, stock bonuses and
rights to purchase restricted stock, not to exceed twenty million (20,000,000)
shares of the Company's Common Stock, to employees and consultants of the
Company who are not officers or directors of the Company.

Summary of Terms of the 1998 Plan

  The 1998 Plan provides for the grant of (i) nonstatutory stock options, (ii)
stock bonuses, and (iii) rights to purchase restricted stock (collectively,
"Stock Awards"). Nonstatutory stock options granted under the 1996 Plan are
intended not to qualify as incentive stock options within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). See
"Federal Income Tax Information" under "Summary of Terms of the 1996 Plan" for
a discussion of the tax treatment of nonstatutory stock options, restricted
stock and stock bonuses.

  Stock Awards may be granted only to consultants or to employees who are not
above the position of vice president of the Company and not then subject to
Section 16 of the Exchange Act and then only so long as the 1998 Plan
qualifies as a "broadly based" plan within the meaning of Rule 4460(i)(1)(A)
of the Rules of the National Association of Securities Dealers, Inc.

                                      10
<PAGE>

  Subject to provisions relating to adjustments upon changes in stock, the
number of shares of stock that may be issued pursuant to Stock Awards shall
not exceed in the aggregate twenty million (20,000,000) shares of the
Company's common stock.

  The exercise price of nonstatutory options under the 1998 Plan is determined
by the Board, but may not be less than 85% of the fair market value of the
Common Stock subject to the option on the date of the option grant. At
September 3, 1999, the closing price of the Company's Common Stock as reported
on the Nasdaq National Market System was $74.44 per share.

  Shares covered by currently outstanding options under the 1998 Plan
typically vest at the rate of 20% of the shares subject to the option on the
first anniversary of the date of hire and 5% of such shares at the end of each
quarter thereafter during the optionee's employment or provision of services
as a consultant. Shares covered by options granted in the future under the
1998 Plan may be subject to different vesting terms. The Board has the power
to accelerate the time during which an option may be exercised.

  The maximum term of options under the 1998 Plan is 10 years. Options under
the 1998 Plan terminate three months after termination of the optionee's
employment or relationship as a consultant of the Company or any affiliate of
the Company, unless the option by its terms specifically provides otherwise.
The option term may also be extended in the event that exercise of the option
is prohibited for specified reasons.

  The purchase price under each restricted stock purchase agreement may not be
less than 85% of the stock's fair market value on the date such award is made.
Notwithstanding the foregoing, the Board may determine that eligible
participants in the 1998 Plan may be awarded stock pursuant to a stock bonus
agreement in consideration for past services actually rendered to the Company
for its benefit. Shares of stock sold or awarded under the Plan may, but need
not, be subject to a repurchase option in favor of the Company in accordance
with a vesting schedule to be determined by the Board. In the event a
participant's continuous status as an employee or consultant terminates, the
Company may repurchase or otherwise re-acquire any or all of the shares of
stock held by that person which have not vested as of the date of termination
under the terms of the stock bonus or restricted stock purchase agreement
between the Company and such person.

  If there is any change in the stock subject to the 1998 Plan or subject to
any Stock Award granted under the 1998 Plan (through merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange
of shares, change in corporate structure or transaction not involving the
receipt of consideration by the Company), the 1998 Plan and Stock Awards
outstanding thereunder will be appropriately adjusted as to the class and the
maximum number of shares subject to such plan, the maximum number of shares
which may be granted to an employee during a calendar year, and the class,
number of shares and price per share of stock subject to such outstanding
Stock Awards.

  The 1998 Plan provides that, in the event of a dissolution, liquidation or
sale of substantially all of the assets of the Company, a specified type of
merger or other corporate reorganization, to the extent permitted by law, any
surviving corporation will be required to either assume Stock Awards
outstanding under the 1998 Plan or substitute similar Stock Awards for those
outstanding under such plan, or such outstanding Stock Awards will continue in
full force and effect. In the event that any surviving corporation declines to
assume or continue Stock Awards outstanding under the 1998 Plan, or to
substitute similar Stock Awards, then with respect to Stock Awards held by
persons then performing services as employees or consultants, the time during
which such Stock Awards may be exercised will be accelerated and the Stock
Awards terminated if not exercised prior to such corporate event. The
acceleration of a Stock Award in the event of an acquisition or similar
corporate event may be viewed as an anti-takeover provision, which may have
the effect of discouraging a proposal to acquire or otherwise obtain control
of the Company.

  The Board may amend or suspend the 1998 Plan without stockholder approval or
ratification at any time or from time to time. The Board, in its sole
discretion, may submit any amendment to the 1998 Plan for stockholder
approval. The Board may terminate the 1998 Plan at any time.

subject, however, to such resolutions, not inconsistent with the provisions of
the Plan, as may be adopted from time to time by the Board. The Board may
abolish the Committee at any time and revest in the Board the administration
of the Plan.

the total combined voting power of all classes of stock of the Company or of
any of its Affiliates unless the exercise price of such Option is at least one
hundred ten percent (110%) of the Fair Market Value of such stock at the date
of grant and the Option is not exercisable after the expiration of five (5)
years from the date of grant, or in the case of a restricted stock purchase
award, the purchase price is at least one hundred percent (100%) of the Fair

                                      B-4
<PAGE>

  (c) Subject to the provisions of Section 13 relating to adjustments upon
changes in stock, following the expiration of the extended reliance period for
compliance with the requirements of Code Section 162(m) set forth in Treasury
Regulations Section 1.162-27(f)(2), no person shall be eligible to be granted
Options covering more than two million (2,000,000) shares of the Company's
common stock in any calendar year.

6. Option Provisions.

  Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. The provisions of separate
Options need not be identical, but each Option shall include (through
incorporation of provisions hereof by reference in the Option or otherwise)
the substance of each of the following provisions:

    (a) Term. No Option shall be exercisable after the expiration of ten (10)
  years from the date it was granted.

    (b) Price. The exercise price of each Incentive Stock Option shall be not
  less than one hundred percent (100%) of the Fair Market Value of the stock
  subject to the Option on the date the Option is granted. Notwithstanding
  the foregoing, an Incentive Stock Option may be granted with an exercise
  price lower than that set forth in the preceding sentence if such Option is
  granted pursuant to an assumption or substitution for another option in a
  manner satisfying the provisions of Section 424(a) of the Code.

    (c) Consideration. The purchase price of stock acquired pursuant to an
  Option shall be paid, to the extent permitted by applicable statutes and
  regulations, either (i) in cash at the time the Option is exercised, or
  (ii) at the discretion of the Board or the Committee, at the time of the
  grant of the Option, (A) by delivery to the Company of other common stock
  of the Company, (B) according to a deferred payment or other arrangement
  (which may include, without limiting the generality of the foregoing, the
  use of other common stock of the Company) with the person to whom the
  Option is granted or to whom the Option is transferred pursuant to
  subsection 6(d), or (C) in any other form of legal consideration that may
  be acceptable to the Board. In the case of any deferred payment
  arrangement, interest shall be payable at least annually and shall be
  charged at the minimum rate of interest necessary to avoid the treatment as
  interest, under any applicable provisions of the Code, of any amounts other
  than amounts stated to be interest under the deferred payment arrangement.

    (d) Transferability. An Incentive Stock Option shall not be transferable
  except by will or by the laws of descent and distribution, and shall be
  exercisable during the lifetime of the person to whom the Incentive Stock
  Option is granted only by such person. A Nonstatutory Stock Option shall
  only be transferable by the Optionee upon such terms and conditions as are
  set forth in the Option Agreement for such Nonstatutory Stock Option, as
  the Board or the Committee shall determine in its discretion, except that
  each Nonstatutory Stock Option may be transferred to the spouse, children,
  lineal ancestors and lineal descendants of the Optionee (or to a trust
  created solely for the benefit of the Optionee and the foregoing persons)
  or to an organization exempt from taxation pursuant to Section 501(c)(3) of
  the Code or to which tax deductible charitable contributions may be made
  under Section 170 of the Code (excluding such organizations classified as
  private foundations under applicable regulations and rulings). The person
  to whom an Option is granted may, by delivering written notice to the
  Company, in a form satisfactory to the Company, designate a third party
  who, in the event of the death of the Optionee, shall thereafter be
  entitled to exercise the Option.

    (e) Vesting. The total number of shares of stock subject to an Option
  may, but need not, be allotted in periodic installments (which may, but
  need not, be equal). The Option Agreement may provide that from time to
  time during each of such installment periods, the Option may become
  exercisable ("vest") with respect to some or all of the shares allotted to
  that period, and may be exercised with respect to some or all of the shares
  allotted to such period and/or any prior period as to which the Option
  became vested but was not fully exercised. The Option may be subject to
  such other terms and conditions on the time or times

                                      B-5
<PAGE>

  when it may be exercised (which may be based on performance or other
  criteria) as the Board may deem appropriate. The provisions of this
  subsection 6(e) are subject to any Option provisions governing the minimum
  number of shares as to which an Option may be exercised.

    (f) Termination of Employment or Relationship as a Director or
  Consultant. In the event an Optionee's Continuous Status as an Employee,
  Director or Consultant terminates (other than upon the Optionee's death or
  disability), the Optionee may exercise his or her Option (to the extent
  that the Optionee was entitled to exercise it at the date of termination)
  but only within such period of time ending on the earlier of (i) the date
  three (3) months after the termination of the Optionee's Continuous Status
  as an Employee, Director or Consultant (or such longer or shorter period
  specified in the Option Agreement), or (ii) the expiration of the term of
  the Option as set forth in the Option Agreement. If, after termination, the
  Optionee does not exercise his or her Option within the time specified in
  the Option Agreement, the Option shall terminate, and the shares covered by
  such Option shall revert to and again become available for issuance under
  the Plan.

    An Optionee's Option Agreement may also provide that if the exercise of
  the Option following the termination of the Optionee's Continuous Status as
  an Employee, Director, or Consultant (other than upon the Optionee's death
  or disability) would result in liability under Section 16(b) of the
  Exchange Act, then the Option shall terminate on the earlier of (i) the
  expiration of the term of the Option set forth in the Option Agreement, or
  (ii) the tenth (10th) day after the last date on which such exercise would
  result in such liability under Section 16(b) of the Exchange Act. Finally,
  an Optionee's Option Agreement may also provide that if the exercise of the
  Option following the termination of the Optionee's Continuous Status as an
  Employee, Director or Consultant (other than upon the Optionee's death or
  disability) would be prohibited at any time solely because the issuance of
  shares would violate the registration requirements under the Act, then the
  Option shall terminate on the earlier of (i) the expiration of the term of
  the Option set forth in the first paragraph of this subsection 6(f), or
  (ii) the expiration of a period of three (3) months after the termination
  of the Optionee's Continuous Status as an Employee, Director or Consultant
  during which the exercise of the Option would not be in violation of such
  registration requirements.

    (g) Disability of Optionee. In the event an Optionee's Continuous Status
  as an Employee, Director or Consultant terminates as a result of the
  Optionee's disability, the Optionee may exercise his or her Option (to the
  extent that the Optionee was entitled to exercise it at the date of
  termination), but only within such period of time ending on the earlier of
  (i) the date twelve (12) months following such termination (or such longer
  or shorter period specified in the Option Agreement), or (ii) the
  expiration of the term of the Option as set forth in the Option Agreement.
  If, at the date of termination, the Optionee is not entitled to exercise
  his or her entire Option, the shares covered by the unexercisable portion
  of the Option shall revert to and again become available for issuance under
  the Plan. If, after termination, the Optionee does not exercise his or her
  Option within the time specified herein, the Option shall terminate, and
  the shares covered by such Option shall revert to and again become
  available for issuance under the Plan.

    (h) Death of Optionee. In the event of the death of an Optionee during,
  or within a period specified in the Option after the termination of, the
  Optionee's Continuous Status as an Employee, Director or Consultant, the
  Option may be exercised (to the extent the Optionee was entitled to
  exercise the Option at the date of death) by the Optionee's estate, by a
  person who acquired the right to exercise the Option by bequest or
  inheritance or by a person designated to exercise the option upon the
  Optionee's death pursuant to subsection 6(d), but only within the period
  ending on the earlier of (i) the date twelve (12) months following the date
  of death (or such longer or shorter period specified in the Option
  Agreement), or (ii) the expiration of the term of such Option as set forth
  in the Option Agreement. 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 revert to and again become
  available for issuance under the Plan. If, after death, the Option is not
  exercised within the time specified herein, the Option shall terminate, and
  the shares covered by such Option shall revert to and again become
  available for issuance under the Plan.


                                      B-6
<PAGE>

    (i) Early Exercise. The Option may, but need not, include a provision
  whereby the Optionee may elect at any time while an Employee, Director or
  Consultant to exercise the Option as to any part or all of the shares
  subject to the Option prior to the full vesting of the Option. Any unvested
  shares so purchased may be subject to a repurchase right in favor of the
  Company or to any other restriction the Board determines to be appropriate.

    (j) Re-Load Options. Without in any way limiting the authority of the
  Board or Committee to make or not to make grants of Options hereunder, the
  Board or Committee shall have the authority (but not an obligation) to
  include as part of any Option Agreement a provision entitling the Optionee
  to a further Option (a "Re-Load Option") in the event the Optionee
  exercises the Option evidenced by the Option agreement, in whole or in
  part, by surrendering other shares of common stock in accordance with this
  Plan and the terms and conditions of the Option Agreement. Any such Re-Load
  Option (i) shall be for a number of shares equal to the number of shares
  surrendered as part or all of the exercise price of such Option; (ii) shall
  have an expiration date which is the same as the expiration date of the
  Option the exercise of which gave rise to such Re-Load Option; and (iii)
  shall have an exercise price which is equal to one hundred percent (100%)
  of the Fair Market Value of the common stock subject to the Re-Load Option
  on the date of exercise of the original Option. Notwithstanding the
  foregoing, a Re-Load Option which is an Incentive Stock Option and which is
  granted to a 10% shareholder (as described in subsection 5(c)), shall have
  an exercise price which is equal to one hundred ten percent (110%) of the
  Fair Market Value of the stock subject to the Re-Load Option on the date of
  exercise of the original Option and shall have a term which is no longer
  than five (5) years.

  Any such Re-Load Option may be an Incentive Stock Option or a Nonstatutory
Stock Option, as the Board or Committee may designate at the time of the grant
of the original Option; provided, however, that the designation of any Re-Load
Option as an Incentive Stock Option shall be subject to the one hundred
thousand dollar ($100,000) annual limitation on exercisability of Incentive
Stock Options described in subsection 12(d) of the Plan and in Section 422(d)
of the Code. There shall be no Re-Load Options on a Re-Load Option. Any such
Re-Load Option shall be subject to the availability of sufficient shares under
subsection 4(a) and shall be subject to such other terms and conditions as the
Board or Committee may determine which are not inconsistent with the express
provisions of the Plan regarding the terms of Options.

7. Terms of Stock Bonuses and Purchases of Restricted Stock.

  Each stock bonus or restricted stock purchase agreement shall be in such
form and shall contain such terms and conditions as the Board or the Committee
shall deem appropriate. The terms and conditions of stock bonus or restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate agreements need not be identical, but each stock bonus
or restricted stock purchase agreement shall include (through incorporation of
provisions hereof by reference in the agreement or otherwise) the substance of
each of the following provisions as appropriate:

    (a) Purchase Price. The purchase price under each restricted stock
  purchase agreement shall be such amount as the Board or Committee shall
  determine and designate in such agreement but in no event shall the
  purchase price be less than eighty-five percent (85%) of the stock's Fair
  Market Value on the date such award is made. Notwithstanding the foregoing,
  the Board or the Committee may determine that eligible participants in the
  Plan may be awarded stock pursuant to a stock bonus agreement in
  consideration for past services actually rendered to the Company for its
  benefit.

    (b) Transferability. No rights under a stock bonus or restricted stock
  purchase agreement shall be transferable except by will or the laws of
  descent and distribution or pursuant to a qualified domestic relations
  order satisfying the requirements of Rule 16b-3 and any administrative
  interpretations or pronouncements thereunder, so long as stock awarded
  under such agreement remains subject to the terms of the agreement.


                                      B-7
<PAGE>

    (c) Consideration. The purchase price of stock acquired pursuant to a
  stock purchase agreement shall be paid either: (i) in cash at the time of
  purchase; (ii) at the discretion of the Board or the Committee, according
  to a deferred payment or other arrangement with the person to whom the
  stock is sold; or (iii) in any other form of legal consideration that may
  be acceptable to the Board or the Committee in its discretion.
  Notwithstanding the foregoing, the Board or the Committee to which
  administration of the Plan has been delegated may award stock pursuant to a
  stock bonus agreement in consideration for past services actually rendered
  to the Company or for its benefit.

    (d) Vesting. Shares of stock sold or awarded under the Plan may, but need
  not, be subject to a repurchase option in favor of the Company in
  accordance with a vesting schedule to be determined by the Board or the
  Committee.

    (e) Termination of Employment or Relationship as a Director or
  Consultant. In the event a Participant's Continuous Status as an Employee,
  Director or Consultant terminates, the Company may repurchase or otherwise
  reacquire any or all of the shares of stock held by that person which have
  not vested as of the date of termination under the terms of the stock bonus
  or restricted stock purchase agreement between the Company and such person.

8. Stock Appreciation Rights.

  (a) The Board or Committee shall have full power and authority, exercisable
in its sole discretion, to grant Stock Appreciation Rights under the Plan to
Employees, Directors of and Consultants to the Company or its Affiliates. To
exercise any outstanding Stock Appreciation Right, the holder must provide
written notice of exercise to the Company in compliance with the provisions of
the Stock Award Agreement evidencing such right. If a Stock Appreciation Right
is granted to an individual who is at the time subject to Section 16(b) of the
Exchange Act (a "Section 16(b) Insider"), the Stock Award Agreement of grant
shall incorporate all the terms and conditions at the time necessary to assure
that the subsequent exercise of such right shall qualify for the safe-harbor
exemption from short-swing profit liability provided by Rule 16b-3 promulgated
under the Exchange Act (or any successor rule or regulation). Except as
provided in subsection 5(d), no limitation shall exist on the aggregate amount
of cash payments the Company may make under the Plan in connection with the
exercise of a Stock Appreciation Right.

  (b) Three types of Stock Appreciation Rights shall be authorized for
issuance under the Plan:

    (1) Tandem Stock Appreciation Rights. Tandem Stock Appreciation Rights
  will be granted appurtenant to an Option, and shall, except as specifically
  set forth in this Section 8, be subject to the same terms and conditions
  applicable to the particular Option grant to which it pertains. Tandem
  Stock Appreciation Rights will require the holder to elect between the
  exercise of the underlying Option for shares of stock and the surrender, in
  whole or in part, of such Option for an appreciation distribution. The
  appreciation distribution payable on the exercised Tandem Right shall be in
  cash (or, if so provided, in an equivalent number of shares of stock based
  on Fair Market Value on the date of the Option surrender) in an amount up
  to the excess of (A) the Fair Market Value (on the date of the Option
  surrender) of the number of shares of stock covered by that portion of the
  surrendered Option in which the Optionee is vested over (B) the aggregate
  exercise price payable for such vested shares.

    (2) Concurrent Stock Appreciation Rights. Concurrent Rights will be
  granted appurtenant to an Option and may apply to all or any portion of the
  shares of stock subject to the underlying Option and shall, except as
  specifically set forth in this Section 8, be subject to the same terms and
  conditions applicable to the particular Option grant to which it pertains.
  A Concurrent Right shall be exercised automatically at the same time the
  underlying Option is exercised with respect to the particular shares of
  stock to which the Concurrent Right pertains. The appreciation distribution
  payable on an exercised Concurrent Right shall be in cash (or, if so
  provided, in an equivalent number of shares of stock based on Fair Market
  Value on the date of the exercise of the Concurrent Right) in an amount
  equal to such portion as shall be determined by the Board or the Committee
  at the time of the grant of the excess of (A) the aggregate Fair Market
  Value

                                      B-8
<PAGE>

  (on the date of the exercise of the Concurrent Right) of the vested shares
  of stock purchased under the underlying Option which have Concurrent Rights
  appurtenant to them over (B) the aggregate exercise price paid for such
  shares.

    (3) Independent Stock Appreciation Rights. Independent Rights will be
  granted independently of any Option and shall, except as specifically set
  forth in this Section 8, be subject to the same terms and conditions
  applicable to Nonstatutory Stock Options as set forth in Section 6. They
  shall be denominated in share equivalents. The appreciation distribution
  payable on the exercised Independent Right shall be not greater than an
  amount equal to the excess of (A) the aggregate Fair Market Value (on the
  date of the exercise of the Independent Right) of a number of shares of
  Company stock equal to the number of share equivalents in which the holder
  is vested under such Independent Right, and with respect to which the
  holder is exercising the Independent Right on such date, over (B) the
  aggregate Fair Market Value (on the date of the grant of the Independent
  Right) of such number of shares of Company stock. The appreciation
  distribution payable on the exercised Independent Right shall be in cash
  or, if so provided, in an equivalent number of shares of stock based on
  Fair Market Value on the date of the exercise of the Independent Right.

9. Cancellation and Re-Grant of Options.

  (a) The Board or the Committee shall have the authority to effect, at any
time and from time to time, (i) the repricing of any outstanding Options
and/or any Stock Appreciation Rights under the Plan and/or (ii) with the
consent of any adversely affected holders of Options and/or Stock Appreciation
Rights, the cancellation of any outstanding Options and/or any Stock
Appreciation Rights under the Plan and the grant in substitution therefor of
new Options and/or Stock Appreciation Rights under the Plan covering the same
or different numbers of shares of stock, but having an exercise price per
share not less than: eighty-five percent (85%) of the Fair Market Value for a
Nonstatutory Stock Option, one hundred percent (100%) of the Fair Market Value
in the case of an Incentive Stock Option or, in the case of an Incentive Stock
Option held by a 10% shareholder (as described in subsection 5(c)), not less
than one hundred ten percent (110%) of the Fair Market Value per share of
stock on the new grant date. Notwithstanding the foregoing, the Board or the
Committee may grant an Option and/or Stock Appreciation Right with an exercise
price lower than that set forth above if such Option and/or Stock Appreciation
Right is granted as part of a transaction to which section 424(a) of the Code
applies.

  (b) Shares subject to an Option or Stock Appreciation Right canceled under
this Section 9 shall continue to be counted against the maximum award of
Options and Stock Appreciation Rights permitted to be granted pursuant to
subsection 5(d) of the Plan. The repricing of an Option and/or Stock
Appreciation Right under this Section 9, resulting in a reduction of the
exercise price, shall be deemed to be a cancellation of the original Option
and/or Stock Appreciation Right and the grant of a substitute Option and/or
Stock Appreciation Right; in the event of such repricing, both the original
and the substituted Options and Stock Appreciation Rights shall be counted
against the maximum awards of Options and Stock Appreciation Rights permitted
to be granted pursuant to subsection 5(d) of the Plan. The provisions of this
subsection 9(b) shall be applicable only to the extent required by Section
162(m) of the Code.

10. Covenants of the Company.

  (a) During the terms of the Stock Awards, the Company shall keep available
at all times the number of shares of stock required to satisfy such Stock
Awards.

  (b) The Company shall seek to obtain from each regulatory commission or
agency having jurisdiction over the Plan such authority as may be required to
issue and sell shares of stock upon exercise of the Stock Award; provided,
however, that this undertaking shall not require the Company to register under
the Securities Act of 1933, as amended (the "Securities Act") either the Plan,
any Stock Award or any stock issued or issuable pursuant to any such Stock
Award. If, after reasonable efforts, the Company is unable to obtain from any
such regulatory commission or agency the authority which counsel for the
Company deems necessary for the lawful issuance and sale of stock under the
Plan, the Company shall be relieved from any liability for failure to issue
and sell stock upon exercise of such Stock Awards unless and until such
authority is obtained.

11. Use of Proceeds from Stock.

  Proceeds from the sale of stock pursuant to Stock Awards shall constitute
general funds of the Company.

12. Miscellaneous.

  (a) The Board shall have the power to accelerate the time at which a Stock
Award may first be exercised or the time during which a Stock Award or any
part thereof will vest pursuant to subsection 6(e), 7(d) or 8(b),
notwithstanding the provisions in the Stock Award stating the time at which it
may first be exercised or the time during which it will vest.

  (b) Neither an Employee, Director or Consultant, nor any person to whom a
Stock Award is transferred in accordance with the Plan, shall be deemed to be
the holder of, or to have any of the rights of a holder with respect to, any
shares subject to such Stock Award unless and until such person has satisfied
all requirements for exercise of the Stock Award pursuant to its terms.

  (c) Nothing in the Plan or any instrument executed or Stock Award granted
pursuant thereto shall confer upon any Employee, Director or Consultant or
other holder of Stock Awards any right to continue in the employ of the
Company or any Affiliate or to continue acting as a Director or Consultant, or
shall affect the right of the Company or any Affiliate to terminate the
employment of any Employee with or without notice and with or without cause,
the right of the Company's Board of Directors and/or the Company's
shareholders to remove any Director pursuant to the terms of the Company's
Bylaws and the provisions of the California Corporations Code, or the right to
terminate the relationship of any Consultant pursuant to the terms of such
Consultant's agreement with the Company or Affiliate.

  (d) To the extent that the aggregate Fair Market Value (determined at the
time of grant) of stock with respect to which Incentive Stock Options are
exercisable for the first time by any Optionee during any calendar year under
all plans of the Company and its Affiliates exceeds one hundred thousand
dollars ($100,000), the Options or portions thereof which exceed such limit
(according to the order in which they were granted) shall be treated as
Nonstatutory Stock Options.

  (e) The Company may require any person to whom a Stock Award is granted, or
any person to whom a Stock Award is transferred in accordance with the Plan,
as a condition of exercising or acquiring stock under any Stock Award, (1) to
give written assurances satisfactory to the Company as to such person's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters, and that he
or she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award; and (2) to
give written assurances satisfactory to the Company stating that such person
is acquiring the stock subject to the Stock Award for such person's own
account and not with any present intention of selling or otherwise
distributing the stock. The foregoing requirements, and any assurances given
pursuant to such requirements, shall be inoperative if (i) the issuance of the
shares upon the exercise or acquisition of stock under the Stock Award has
been registered under a then currently effective registration statement under
the Securities Act, or (ii) as to any particular requirement, a determination
is made by counsel for the Company that such requirement need not be met in
the circumstances under the then applicable securities laws. The Company may,
upon advice of counsel to the Company, place legends on stock certificates
issued under the Plan as such counsel deems necessary or appropriate in order
to comply with applicable securities laws, including, but not limited to,
legends restricting the transfer of the stock.

  (f) To the extent provided by the terms of a Stock Award Agreement, the
person to whom a Stock Award is granted may satisfy any federal, state or
local tax withholding obligation relating to the exercise or acquisition of
stock under a Stock Award by any of the following means or by a combination of
such means: (1) tendering a cash payment; (2) authorizing the Company to
withhold shares from the shares of the common stock otherwise issuable to the
participant as a result of the exercise or acquisition of stock under the
Stock Award; or (3) delivering to the Company owned and unencumbered shares of
the common stock of the Company.

13. Adjustments Upon Changes in Stock.

  (a) If any change is made in the stock subject to the Plan, or subject to
any Stock Award, without the receipt of consideration by the Company (through
merger, consolidation, reorganization, recapitalization, reincorporation,
stock dividend, dividend in property other than cash, stock split, liquidating
dividend, combination of shares, exchange of shares, change in corporate
structure or other transaction not involving the receipt of consideration by
the Company), the Plan will be appropriately adjusted in the class(es) and
maximum number of shares subject to the Plan pursuant to subsection 4(a) and
the maximum number of shares subject to award to any person during any
calendar year pursuant to subsection 5(c), and the outstanding Stock Awards
will be appropriately adjusted in the class(es) and number of shares and price
per share of stock subject to such outstanding Stock Awards. Such adjustments
shall be made by the Board or the Committee, the determination of which shall
be final, binding and conclusive. (The conversion of any convertible
securities of the Company shall not be treated as a "transaction not involving
the receipt of consideration by the Company".)

  (b) In the event of: (1) a dissolution, liquidation or sale of substantially
all of the assets of the Company; (2) a merger or consolidation in which the
Company is not the surviving corporation; or (3) a reverse merger in which the
Company is the surviving corporation but the shares of the Company's common
stock outstanding immediately preceding the merger are converted by virtue of
the merger into other property, whether in the form of securities, cash or
otherwise, then to the extent permitted by applicable law: (i) any surviving
corporation or an Affiliate of such surviving corporation shall assume any
Stock Awards outstanding under the Plan or shall substitute similar Stock
Awards for those outstanding under the Plan, or (ii) such Stock Awards shall
continue in full force and effect. In the event any surviving corporation and
its Affiliates refuse to assume or continue such Stock Awards, or to
substitute similar options for those outstanding under the Plan, then, with
respect to Stock Awards held by persons then performing services as Employees,
Directors or Consultants, the time during which such Stock Awards may be
exercised shall be accelerated and the Stock Awards terminated if not
exercised prior to such event.

14. Amendment of the Plan and Stock Awards.

  (a) The Board at any time, and from time to time, may amend the Plan.
However, except as provided in Section 13 relating to adjustments upon changes
in stock, no amendment shall be effective unless approved by the shareholders
of the Company within twelve (12) months before or after the adoption of the
amendment, where the amendment will:

    (i) Increase the number of shares reserved for Stock Awards under the
  Plan;

    (ii) Modify the requirements as to eligibility for participation in the
  Plan (to the extent such modification requires shareholder approval in
  order for the Plan to satisfy the requirements of Section 422 of the Code);
  or

    (iii) Modify the Plan in any other way if such modification requires
  shareholder approval in order for the Plan to satisfy the requirements of
  Section 422 of the Code or to comply with the requirements of Rule 16b-3.

  (b) The Board may in its sole discretion submit any other amendment to the
Plan for shareholder approval, including, but not limited to, amendments to
the Plan intended to satisfy the requirements of Section 162(m) of the Code
and the regulations promulgated thereunder regarding the exclusion of
performance-based compensation from the limit on corporate deductibility of
compensation paid to certain executive officers.

  (c) It is expressly contemplated that the Board may amend the Plan in any
respect the Board deems necessary or advisable to provide eligible Employees,
Directors or Consultants with the maximum benefits provided or to be provided
under the provisions of the Code and the regulations promulgated thereunder
relating to Incentive Stock Options and/or to bring the Plan and/or Incentive
Stock Options granted under it into compliance therewith.

  (d) Rights and obligations under any Stock Award granted before amendment of
the Plan shall not be impaired by any amendment of the Plan unless (i) the
Company requests the consent of the person to whom the Stock Award was granted
and (ii) such person consents in writing.

  (e) The Board at any time, and from time to time, may amend the terms of any
one or more Stock Award; provided, however, that the rights and obligations
under any Stock Award shall not be impaired by any such amendment unless (i)
the Company requests the consent of the person to whom the Stock Award was
granted and (ii) such person consents in writing.

15. Termination or Suspension of the Plan.

  (a) The Board may suspend or terminate the Plan at any time. Unless sooner
terminated, the Plan shall terminate ten (10) years from the date the Plan is
adopted by the Board or approved by the shareholders of the Company, whichever
is earlier. No Stock Awards may be granted under the Plan while the Plan is
suspended or after it is terminated.

  (b) Rights and obligations under any Stock Award granted while the Plan is
in effect shall not be impaired by suspension or termination of the Plan,
except with the consent of the person to whom the Stock Award was granted.

16. Effective Date of Plan.

  The Plan shall become effective on the effective date of the registration
statement with respect to the Company's initial public offering of shares of
common stock, but no Stock Awards granted under the Plan shall be exercised
unless and until the Plan has been approved by the shareholders of the
Company, which approval shall be within twelve (12) months before or after the
date the Plan is adopted by the Board.
