determined on a pro rata basis according to the number of fiscal quarters (i.e.,
fiscal quarters ending November 1, February 1, May 1 and August 1) elapsed since
the prior annual vesting date and provided further, that upon any Change in
Control (as defined below), so long as Director was a member of the Company's
board of directors on the day immediately prior to such Change in Control, all
of the Tranche I Options granted to Director shall become vested and immediately
exercisable.  For purposes hereof, a "Change in Control" shall be deemed to
                                      -----------------
occur upon the first date that the Investors and their affiliates collectively
cease to own at least 35% of the aggregate number of shares of common stock of
the Company that they own on the date hereof (as adjusted for stock splits,
stock dividends and recapitalization and for exchanges in connection with a
merger, consolidation, reorganization or sale).

          (c)  Early Expiration of Options. Any portion of the Options that has
               ---------------------------
not vested and become exercisable prior to the Termination Date (as defined in
Section 3(b) below) will expire on the Termination Date and may not be exercised
under any circumstance.  Any portion of the Options that has vested and become
exercisable prior to the Termination Date will expire on the earlier of

                                      -3-


(i) 30 days after the Termination Date (provided that such period shall be
extended to six (6) months after the Termination Date, in the event of
Director's termination due to death or "disability" (as defined in Code Section
22(a)(3))) and (ii) the Expiration Date. Notwithstanding any provision in this
Agreement to the contrary, any portion of the Options which has not been
exercised prior to or in connection with a Sale of the Company shall expire upon
the consummation of any such transaction.

          (d)  Procedure for Exercise.  At any time after all or any portion of
               ----------------------
the Options have become exercisable with respect to any Option Shares (as
defined in Section 3(a) hereof) and prior to the Expiration Date (except as
provided for in Section 2(c) above), Director may exercise all or a portion of
the Options with respect to Option Shares vested pursuant to paragraph 2(b)(ii)
above by delivering written notice of exercise to the Company, together with (i)
a written acknowledgment that Director has read and has been afforded an
opportunity to ask questions of management of the Company regarding all
financial and other information provided to Director regarding the Company, (ii)
an executed consent from Director's spouse (if any) in the form of Exhibit B
                                                                   ---------
attached hereto and (iii) payment in full by delivery of a certified bank check,
wire transfer of immediately available funds or a personal check in the amount
(the "Option Price") equal to the product of the Tranche I Option Price
      ------------
multiplied by the number of Tranche I Option Shares to be acquired.  As a
condition to any exercise of the Options, Director will permit the Company to
deliver to him or her all financial and other information regarding the Company
and its Subsidiaries which it believes necessary to enable Director to make an
informed investment decision.  If, at any time subsequent to the date Director
exercises any portion of the Options and prior to the occurrence of a
Termination Event (as defined in Section 3(g) hereof), Director becomes legally
married (whether in the first instance or to a different spouse), Director shall
cause Director's spouse to execute and deliver a consent in the form of Exhibit
                                                                        -------
B attached hereto.  Director's failure to deliver the Company an executed
- -
consent in the form of Exhibit B at any time when Director would otherwise be
                       ---------
required to deliver such consent shall constitute Director's continuing
representation and warranty that Director is not legally married as of such
date.

          (e)  Securities Laws Restrictions.  Director represents that when
               ----------------------------
Director exercises any of the Options he or she will be purchasing Option Shares
for Director's own account and not on behalf of others.  Director understands
and acknowledges that federal and state securities laws govern and restrict
Director's right to offer, sell or otherwise dispose of any Option Shares unless
Director's offer, sale or other disposition thereof is registered under the 1933
Act and state securities laws or, in the opinion of the Company's counsel, such
offer, sale or other disposition is exempt from registration thereunder.
Director agrees that he or she will not offer, sell or otherwise dispose of any
Option Shares in any manner which would:  (i) require the Company to file any
registration statement (or similar filing under state law) with the Securities
and Exchange Commission or to amend or supplement any such filing or (ii)
violate or cause the Company to violate the 1933 Act, the rules and regulations
promulgated thereunder or any other state or federal law.  Director further
understands that the certificates for any Option Shares which Director purchases
will bear the legend set forth in paragraph 5 hereof or such other legends as
the Company deems necessary or desirable in connection with the 1933 Act or
other rules, regulations or laws.

                                      -4-


          (f)  Non-Transferability of Options.  The Options are personal to
               ------------------------------
Director and are not transferable by Director except by will or pursuant to the
laws of descent or distribution.  Only Director or his legal guardian or
representative may exercise the Options.

          3.   Repurchase Option.
               -----------------

          (a)  Definitions.  The following terms are defined as follows:

          "Fair Market Value" of each share of Director Stock means the market
           -----------------
value as determined in good faith by the Company's board of directors.

          "Option Shares" means the Tranche I Option Shares.  For purposes of
           -------------
this paragraph 3 and paragraph 4, Option Shares issued upon exercise of any
Options will be deemed to be Director Stock.

          "Original Cost" of each share of Director Stock will be equal to the
           -------------
price paid by the Director for each share of Common Stock (as proportionally
adjusted for all stock splits, stock dividends and other recapitalizations
affecting the Common Stock subsequent to the date hereof).

          "Subsidiary" means any corporation of which shares of stock having a
           ----------
majority of the general voting power in electing the board of directors are, at
the time as of which any determination is being made, owned by the Company
either directly or through its Subsidiaries.

          (b)  Repurchase Option.  In the event that Director is no longer a
               -----------------
member of the Company's board of directors for any reason (the date of such
termination being referred to herein as the "Termination Date"), the Director
                                             ----------------
Stock, whether held by Director or one or more transferees, will be subject to
repurchase by the Company and the Investors (each of the aforementioned, solely
at their option) pursuant to the terms and conditions set forth in this
paragraph 3 (the "Repurchase Option").
                  -----------------

          (c)  Repurchase Price. If Director is no longer a member of the
               ----------------
Company's board of directors for any reason, then on or after the Termination
Date, the Company and the Investors may elect to purchase up to 50% of the
Director Stock at a price per share equal to Fair Market Value (as of the
Termination Date).

          (d)  Repurchase Procedures.  The Company may elect to exercise the
               ---------------------
right to purchase all or any portion of the shares of Director Stock pursuant to
the Repurchase Option by delivering written notice (the "Repurchase Notice") to
                                                         -----------------
the holder or holders of the Director Stock within 45 days of the Termination
Date (provided that such notice may be delivered in the case of any Director
Stock issued after the Termination Date, within 45 days of the date any such
Director Stock is issued).  The Repurchase Notice will set forth the number of
shares of Director Stock to be acquired from such holder(s), the aggregate
consideration to be paid for such shares and the time and place for the closing
of the transaction.  If any Director Stock is held by any transferees of
Director, the Company shall purchase the shares elected to be purchased from
such holder(s) of Director Stock, pro rata according to the number of shares of
Director Stock held by such holder(s) at the time of

                                      -5-


delivery of such Repurchase Notice (determined as nearly as practicable to the
nearest share). If Director Stock of different classes is to be purchased by the
Company and Director Stock is held by any transferees of Director, the number of
shares of each class of Director Stock to be purchased will be allocated among
such holders, pro rata according to the total number of shares of Director Stock
to be purchased from such persons.

          (e)   Investor Rights.
                ---------------

          (i)   If for any reason the Company does not elect to purchase all of
the Director Stock pursuant to the Repurchase Option prior to the last to occur
of (i) the 45/th/ day following the Termination Date or (ii) the 45/th/ day
following the date any Director Stock is issued, in the case of any Director
Stock issued after the Termination Date, the Investors will be entitled to
exercise the Repurchase Option, in the manner set forth in this paragraph 3, for
the Director Stock the Company has not elected to purchase (the "Available
                                                                 ---------
Shares").  As soon as practicable, but in any event within thirty (30) days
- ------
after the Company determines that there will be any Available Shares (and in no
event later than the last to occur of (i) the 45/th/ day following the
Termination Date or (ii) the 45/th/ day following the date any Director Stock is
issued, in the case of any Director Stock issued after the Termination Date),
the Company will deliver written notice (the "Option Notice") to the Investors
                                              -------------
setting forth the number of Available Shares and the price for each Available
Share.

          (ii)  Each of the Investors will initially be permitted to purchase
its pro rata share (based upon the number of shares of Common Stock then held by
such Investors) of the Available Shares. Each Investor may elect to purchase any
number of the Available Shares (subject to the preceding sentence) by delivering
written notice to the Company within 30 days after receipt of the Option Notice
from the Company (such 30-day period being referred to herein as the "Election
                                                                      --------
Period").
- ------

          (iii) As soon as practicable but in any event within five (5) days
after the expiration of the Election Period, the Company will, if necessary,
notify the Investors electing to purchase Available Shares of any Available
Shares which Investors have elected not to purchase and each of the electing
Investors will be entitled to purchase the remaining Available Shares on the
same terms as described above (the "Second Option Notice"); provided that if in
                                    --------------------
the aggregate such Investors elect to purchase more than the remaining Available
Shares, such remaining Available Shares purchased by each such Investor will be
reduced on a pro rata basis based upon the number of shares of Common Stock then
held by such Investors.  Each Investor may elect to purchase any of the
remaining Available Shares available to such Investor by delivering written
notice to the Company within 5 days after the delivery of the Second Option
Notice (with such 5-day period referred to herein as the "Second Election
                                                          ---------------
Period").
- ------

          (iv)  As soon as practicable but in any event within five days after
the expiration of the Election Period or the Second Election Period (if any) the
Company will, if necessary, notify the holder(s) of Director Stock as to the
number of shares of Director Stock being purchased from the holder(s) by the
Investors (the "Supplemental Repurchase Notice").  At the time the Company
                ------------------------------
delivers a Supplemental Repurchase Notice to the holder(s) of Director Stock,
the Company will also deliver to each electing Investor written notice setting
forth the number of shares of Director Stock

                                      -6-


the Company and each Investor will acquire, the aggregate purchase price to be
paid and the time and place of the closing of the transaction.

          (f)  Closing.  The closing of the transactions contemplated by this
               -------
paragraph 3 will take place on the date designated by the Company in the
Repurchase Notice or the Supplemental Repurchase Notice, as the case may be,
which date will not be more than 90 days after the delivery of such notice.  The
Company and/or the Investors, as the case may be, will pay for the Director
Stock to be purchased pursuant to the Repurchase Option by delivery of, in the
case of each Investor, a check payable to the holder of such Director Stock, and
in the case of the Company (i) first, by cancellation of any amounts due and
owing under any promissory note issued by Director to the Company, (ii) second,
by a check payable to the holder of such Director Stock up to the amount of the
Original Cost therefor paid in cash by Director and (iii) a note or notes
payable in one installment on the first anniversary of the closing of such
purchase and bearing interest at a rate per annum equal to 8% (it being agreed
that the Company may, in its sole discretion, elect to make any payment under
this clause (iii) in cash), in any case in the aggregate amount of the purchase
price for such shares. Any notes issued by the Company pursuant to this
paragraph 3(f) shall be subject to any restrictive covenants to which the
Company is subject at the time of such purchase.  Notwithstanding anything to
the contrary contained in this Agreement, all repurchases of Director Stock by
the Company will be subject to applicable restrictions contained in the
California General Corporation Law and in the Company's and its Subsidiaries'
debt and equity financing agreements.  If any such restrictions prohibit the
repurchase of Director Stock hereunder which the Company is otherwise entitled
to make, the Company may make such repurchases as soon as it is permitted to do
so under such restrictions.  The Company and/or the Investors, as the case may
be, will receive customary repre  sentations and warranties from each seller
regarding the sale of the Director Stock, including, but not limited to, the
representation that such seller has good and marketable title to the Director
Stock to be transferred free and clear of all liens, claims and other
encumbrances.

          (g)  Termination of Repurchase Option.  The provisions of this
               --------------------------------
paragraph 3 will terminate upon the first to occur of (i) a Sale of the Company
and (ii) the first date subsequent to the date that the Company sells any shares
of its common stock pursuant to a registration statement filed under the 1933
Act (collectively, a "Termination Event").
                      -----------------

          4.   Restrictions on Transfer.
               ------------------------

          (a)  Transfer of Director Stock.  Director will not sell, pledge or
               --------------------------
otherwise transfer any interest in any shares of Director Stock, except pursuant
to the provisions of paragraphs 3, 4(b), 7 or 8 hereof.

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"),
          AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE

          (b)  No holder of Director Stock or Options Shares may sell, transfer
or dispose of any Director Stock or Option Shares (except pursuant to an
effective registration statement under the Securities Act of 1933) without first
delivering to the Company an opinion of counsel reasonably acceptable in form
and substance to the Company (which counsel shall be reasonably acceptable to
the Company) that registration under the 1933 Act is not required in connection
with such transfer.

          6.   Definition of Director Stock and Option Shares.  For all purposes
               ----------------------------------------------
of this Agreement, Director Stock and Option Shares will continue to be Director
Stock and Option Shares in the hands of any holder other than Director (except
for the Company, the Investors or purchasers pursuant to an offering registered
under the 1933 Act or purchasers pursuant to a Rule 144 transaction (other than
a Rule 144(k) transaction occurring prior to the time of a closing of a Public
Offering (as defined in Section 8 below)), and each such other holder of
Director Stock and Option Shares will succeed to all rights and obligations
attributable to Director as a holder of Director Stock and Option Shares
hereunder.  Director Stock and Option Shares will also include shares of the

                                      -8-


Company's capital stock issued with respect to shares of Director Stock and
Option Shares by way of a stock split, stock dividend or other recapitalization.

          7.   Sale of the Company
               -------------------

          (a)  If the holders of a majority of the shares of the Company's
common stock held by the Investors approve (and, in the case of any sale or
other fundamental change which requires the approval of the board of directors
of a California corporation pursuant to the California General Corporation Law,
the Company's board of directors shall have approved such sale) a sale of all or
substantially all of the Company's assets determined on a consolidated basis or
a sale of all or substantially all of the Company's outstanding capital stock
(whether by merger, recapitalization, consolidation, reorganization, combination
or otherwise) to an Independent Third Party or group of Independent Third
Parties (an "Approved Sale"), each holder of Director Stock and Option Shares
             -------------
will vote for, consent to and raise no objections against such Approved Sale.
If the Approved Sale is structured as (i) a merger or consolidation, each holder
of Director Stock and Options Shares will waive any dissenters' rights,
appraisal rights or similar rights in connection with such merger or
consolidation or (ii) sale of stock, each holder of Director Stock and Option
Shares will agree to sell all of his or her shares of Director Stock and Options
Shares and rights to acquire shares of Director Stock and Option Shares on the
terms and conditions approved by the Company's board of directors and the
holders of a majority of the Company's common stock then outstanding.  Each
holder of Director Stock and Option Shares will take all necessary or desirable
actions in connection with the consummation of the Approved Sale as requested by
the Company.

          (b)  The obligations of the holders of Common Stock with respect to
the Approved Sale of the Company are subject to the satisfaction of the
following conditions: (i) upon the consummation of the Approved Sale, each
holder of Common Stock will receive the same form of consideration and the same
portion of the aggregate consideration that such holders of Common Stock would
have received if such aggregate consideration had been distributed by the
Company in complete liquidation pursuant to the rights and preferences set forth
in the Company's Articles of Incorporation as in effect immediately prior to
such Approved Sale; (ii) if any holders of a class of Common Stock are given an
option as to the form and amount of consideration to be received, each holder of
such class of Common Stock will be given the same option; and (iii) each holder
of then currently exercisable rights to acquire shares of a class of Common
Stock will be given an opportunity to exercise such rights prior to the
consummation of the Approved Sale and participate in such sale as holders of
such class of Common Stock.

          (c)  If the Company or the holders of the Company's securities enter
into any negotiation or transaction for which Rule 506 (or any similar rule then
in effect) promulgated by the Securities Exchange Commission may be available
with respect to such negotiation or transaction (including a merger,
consolidation or other reorganization), the holders of Director Stock and Option
Shares will, at the request of the Company, appoint a purchaser representative
(as such term is defined in Rule 501) reasonably acceptable to the Company.  If
any holder of Director Stock or Option Shares appoints a purchaser
representative designated by the Company, the Company will pay the fees of such
purchaser representative, but if any holder of Director Stock or Option Shares
declines to appoint the purchaser representative designated by the Company, such
holder will

                                      -9-


appoint another purchaser representative, and such holder will be responsible
for the fees of the purchaser representative so appointed.

          (d)  Director and the other holders of Director Stock and Option
Shares (if any) will bear their pro-rata share (based upon the number of shares
sold) of the costs of any sale of Director Stock and Option Shares pursuant to
an Approved Sale to the extent such costs are incurred for the benefit of all
holders of Common Stock and are not otherwise paid by the Company or the
acquiring party. Costs incurred by Director and the other holders of Director
Stock and Option Shares on their own behalf will not be considered costs of the
transaction hereunder.

          (e)  The provisions of this paragraph 7 will terminate upon the
closing of a Public Offering (as defined below).

          8.   Public Offering.  In the event that the Company's board of
               ---------------
directors and the holders of a majority of the Company's shares of common stock
then outstanding approve an initial public offering and sale of the Company's
common stock (a "Public Offering") pursuant to an effective registration
                 ---------------
statement under the 1933 Act, the holders of Director Stock and Option Shares
will take all necessary or desirable actions in connection with the consummation
of the Public Offering.  In the event that such Public Offering is an
underwritten offering and the managing underwriters advise the Company in
writing that in their opinion the Common Stock structure will adversely affect
the marketability of the offering, each holder of Director Stock and Option
Shares will consent to and vote for a recapitalization, reorganization and/or
exchange of the Common Stock into securities that the managing underwriters, the
Company's board of directors and holders of a majority of the shares of Common
Stock then outstanding find acceptable and will take all necessary or desirable
actions in connection with the consummation of the recapitalization,
reorganization and/or exchange.

          9.   Holdback Agreement.  No holder of Director Stock or Option Shares
               ------------------
will effect any public sale or distribution (including sales pursuant to Rule
144 of the 1933 Act) of any Director Stock or Option Shares or of any other
capital stock or equity securities of the Company, or any securities, options or
rights convertible into or exchangeable or exercisable for such stock or
securities, during the seven days prior to and the 180-day period beginning on
the effective date of any underwritten public offering of the Company's common
stock, except as part of such underwritten public offering.  The restrictions on
the transfer set forth in this Section 9 shall continue with respect to each
share of Director Stock and Option Shares until the date on which such share has
been transferred pursuant to an offering registered under the 1933 Act or to the
public through a broker, dealer or market maker pursuant to the provisions of
Rule 144 (other than Rule 144(k)), adopted under the 1933 Act.

event that any ruling of any court or governmental authority calls into question
the validity of any portion of this Agreement, the parties hereto shall consult
with each other concerning such matters and shall negotiate in good faith a

validity is called into question.

               -------------
AND BINDING EFFECT OF THIS AGREEMENT WILL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA, WITHOUT GIVING EFFECT TO
ANY CHOICE OF LAW OR CONFLICT OF LAW PROVISION OR RULE (WHETHER OF THE STATE OF
CALIFORNIA OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE
LAW OF ANY JURISDICTION OTHER THAN THE STATE OF CALIFORNIA.  EACH OF THE PARTIES
HERETO SUBMITS TO THE JURISDICTION IN ANY STATE OR FEDERAL COURT LOCATED IN THE
