                               CO-SALE PROVISIONS

     Notwithstanding anything herein to the contrary, the following provisions
of this Article II shall terminate immediately prior to the closing of a
Qualified Public Offering and shall not apply with respect to any Qualified
Public Offering.

     Section 2.1 Restrictions on Transfer. Each Stockholder agrees that he will
not, without the prior written consent of a Majority Interest of the Investors,
transfer all or any portion of the Shares now owned or hereafter acquired by
him, except in connection with, and in compliance with the conditions of, any of
the following:

         (a) Transfers effected pursuant to Sections 2.2 and 2.3 in each case
made in accordance with the procedures set forth therein;

         (b) Transfers by any Stockholder to his spouse or children or to a
trust of which he is the settlor and a trustee for the benefit of his spouse or
children; provided, that any such trust or entity does not require or permit
distribution of such Shares during the term of this Agreement; and provided
further, that the transferee shall have entered into a Joinder Agreement in the
form attached as Exhibit A providing that all Shares so transferred shall
continue to be subject to all provisions of this Agreement as if such Shares
were still held by such Stockholder, except that no further transfer shall
thereafter be permitted hereunder except in compliance with Sections 2.2 and
2.3;

         (c) Transfers upon the death of any Stockholder to his heirs, executors
or administrators or to a trust under his will or Transfers between such
Stockholder and his guardian or conservator, provided that the transferee shall
have entered into a Joinder Agreement in the form attached as Exhibit A
providing that all Shares so transferred shall continue to be subject to all
provisions of this Agreement as if such Shares were still held by such
Stockholder, except that no further transfer shall thereafter be permitted
hereunder except in compliance with Sections 2.2 and 2.3; and

         (d) in addition to the Transfers specified in items (a), (b) and (c)
above, Transfers by Blaise Barrelet and/or Agnes Barrelet of Ten Million
(10,000,000) shares of Common Stock in the aggregate, and Transfers by Michael
Christian of Five Hundred Twenty-Five Thousand Four Hundred Fifty-Four (525,454)
shares of Common Stock in the aggregate, in each case as appropriately adjusted
for any stock split, combination, reorganization, recapitalization,
reclassification, stock distribution, stock dividend or similar event.


                                       4
<PAGE>   5


     Any permitted transferee described in clauses (b) or (c) above shall be
referred to herein as a "Permitted Transferee." Anything to the contrary in this
Agreement notwithstanding, Permitted Transferees shall take any Shares so
transferred subject to all provisions of this Agreement as if such Shares were
still held by the transferring Stockholder, whether or not they so agree in
writing.

     Section 2.2 Right of Last Refusal. In the event that any of the
Stockholders, including any of their Permitted Transferees, receives a bona fide
offer to purchase all or any portion of the Shares held by such person (a
"Transaction Offer") from a non-Affiliate (the "Offeror"), such Stockholders or
Permitted Transferees (a "Transferring Stockholder") may, subject to the
provisions of Section 2.3 hereof, transfer such Shares pursuant to and in
accordance with the following provisions of this Section 2.2:

         (a) Such Transferring Stockholder shall cause the Transaction Offer and
all of the terms thereof to be reduced to writing and shall notify each of the
Investors of his wish to accept the Transaction Offer and otherwise comply with
the provisions of this Section 2.2 and, if applicable, Section 2.3 (such notice,
the "Offer Notice"). The Transferring Stockholder's Offer Notice shall
constitute an irrevocable offer to sell the Shares which are the subject of the
Transaction Offer to the Investors, on the basis described below at a purchase
price equal to the price contained in, and on the same terms and conditions of,
the Transaction Offer. The Offer Notice shall be accompanied by a true copy of
the Transaction Offer (which shall identify the Offeror and all relevant
information in connection therewith).

         (b) Upon receipt of an Offer Notice, the Investors may elect to accept
the offer to sell with respect to all of the Shares subject thereto and shall
give written notice of such election to the Transferring Stockholder as provided
below. Each Investor shall have the right to offer to purchase up to that number
of Shares covered by the Transaction Offer as shall be equal to the product
obtained by multiplying (i) the total number of Shares subject to the
Transaction Offer by (ii) a fraction, the numerator of which is the total number
of Shares owned by such Investor on the date of the Offer Notice on an as
converted basis (including for this purpose any shares of Common Stock issuable
upon conversion of the Preferred Stock), and the denominator of which is the
total number of Shares then held by all Investors on the date of the Offer
Notice also on an as converted basis, subject to increase as hereinafter
provided. The number of Shares that each Investor is entitled to purchase under
this Section 2.2 as provided in the immediately preceding sentence shall be
referred to as its "Pro Rata Fraction." In the event an Investor does not wish
to purchase its Pro Rata Fraction, then any Investors who so elect to purchase
shall have the right to offer to purchase, on a pro rata basis with any other
Investors who so elect, any Pro Rata Fraction not purchased by such Investor.

     Each Investor shall have the right to accept the Transaction Offer by
giving notice of such acceptance to the Transferring Stockholder as provided
herein within thirty (30) calendar days after receipt of the Offer Notice (the
"Election Period"), which notice shall indicate the maximum number of Shares
subject thereto which the Investor is willing to purchase in the event fewer
than all Investors elect to purchase their Pro Rata Fractions. In the event that
the price set forth in the Offer Notice is stated in consideration other than
cash or cash equivalents, the Transferring Stockholder and a Majority Interest
of the Investors shall determine the fair market

                                       5
<PAGE>   6

value of such consideration, reasonably and in good faith; provided that, if the
Transferring Stockholder and such Investors are unable to agree on the fair
market value of such consideration, then the fair market value of such
consideration shall be the average of three appraisals conducted by three
independent investment bankers, such that (i) the Transferring Stockholder shall
select and pay the fees of the first investment banker, (ii) such Investors
shall select and pay the fees of the second investment banker and (iii) the
first two investment bankers selected shall select a third investment banker,
the fees of which shall be paid equally by the Transferring Stockholder, on the
one hand, and such Investors, on the other hand. The Investors may exercise
their right to purchase under this Section 2.2 by payment of such fair market
value in cash or cash equivalents. The Transferring Stockholder shall notify the
Investors promptly following any lapse of the rights to purchase under this
Section 2.2 without acceptance thereof or any rejection of such rights.

     Upon the expiration of the Election Period, the number of Shares to be
purchased by each Investor (and if applicable by the Company or its assignees)
shall be determined as follows: (x) there shall first be allocated to each
Investor a number of Shares equal to the lesser of (A) the number of Shares as
to which such Investor accepted the Transaction Offer or (B) such Investor's Pro
Rata Fraction, and (y) second, the balance, if any, not allocated under clause
(x) above, shall be allocated to those Investors who accepted the Transaction
Offer as to a number of Shares which exceeded their respective Pro Rata
Fractions, in each case on a pro rata basis in proportion to the amount of such
excess. The closing for any purchase of Shares by the Investors under this
Section 2.2 shall take place within twenty-one (21) calendar days after the
expiration of the Election Period at the place and on the date specified by a
Majority Interest of the Investors (as to purchases by the Investors).

         (c) In the event that the Investors do not elect to exercise the rights
to purchase under this Section 2.2 with respect to all of the Shares proposed to
be sold, the Transferring Stockholder may sell any such unsold Shares to the
Offeror on the terms and conditions set forth in the Offer Notice, subject to
the provisions of Section 2.3. If the Transferring Stockholder's sale to an
Offeror is not consummated in accordance with the terms of the Transaction Offer
within the later of (i) ninety (90) calendar days after the expiration of the
right of last refusal under this Section 2.2 and the Co-Sale Option set forth in
Section 2.3 below, if applicable, and (ii) the satisfaction of all governmental
approval or filing requirements, the Transaction Offer shall be deemed to lapse,
and any transfers of Shares pursuant to such Transaction Offer shall be deemed
to be in violation of the provisions of this Agreement unless the Investors and
the Company are once again afforded the right of last refusal provided for
herein with respect to such Transaction Offer.

     Section 2.3 Co-Sale Option of Investors. In the event that any Transferring
Stockholder receives a Transaction Offer from an Offeror, and the right to
purchase under Section 2.2 is not exercised by the Investors as to all Shares,
such Transferring Stockholder may transfer any such unsold Shares only pursuant
to and in accordance with the following provisions of this Section 2.3:

         (a) Each of the Investors shall have the right to participate in the
Transaction Offer with respect to any Shares subject thereto which are not
purchased pursuant to

                                       6
<PAGE>   7

Section 2.2 by giving written notice (the "Acceptance Notice") to the
Transferring Stockholder on or before the last day of the Election Period (the
"Co-Sale Option"). Each Acceptance Notice shall indicate the maximum number of
Shares the Investor wishes to sell including the number of Shares it would sell
if one or more other Investors do not elect to participate in the sale on the
terms and conditions stated in the Offer Notice. Any Investor holding Preferred
Stock shall be permitted to sell to the relevant Offeror in connection with any
exercise of the Co-Sale Option, at its option, shares of Common Stock acquired
upon conversion of such Preferred Stock, or an option to acquire such Common
Stock when it receives the same upon such conversion at the election of such
Investor with the same effect as if Common Stock were being conveyed.

         (b) Each Investor shall have the right to sell a portion of its Shares
pursuant to the Transaction Offer which is equal to or less than the product
obtained by multiplying (i) the total number of Shares subject to the
Transaction Offer and available for sale to the Offeror by (ii) a fraction, the
numerator of which is the total number of Shares owned by such Investor on the
date of the Offer Notice on an as converted basis (including all shares of
Common Stock issuable upon conversion of the Preferred Stock) and the
denominator of which is the total number of Shares then held by all Investors
and the Transferring Stockholder (including any of his Permitted Transferees) on
the date of the Offer Notice, also on an as converted basis and including
(without duplication) all shares of Common Stock issuable upon the conversion of
the Preferred Stock. To the extent one or more Investors elect not to sell, or
fail to exercise their rights to sell, the full amount of such Shares which they
are entitled to sell pursuant to this Section 2.3, the right of Investors who
have elected to sell Shares shall be increased proportionately based on their
relative holdings and such other Investors shall have an additional five (5)
business days from the date upon which they are notified of such election or
failure to exercise in which to increase the number of Shares to be sold by them
hereunder.

         (c) Within ten (10) calendar days after the date by which the Investors
were first required to notify the Transferring Stockholder of their intent to
participate, the Transferring Stockholder shall notify the Company, which in
turn shall promptly notify each participating Investor of the number of Shares
held by such Investor that will be included in the sale and the date on which
the Transaction Offer will be consummated, which shall be no later than the
later of (i) thirty (30) calendar days after the date by which the Investors
were required to notify the Transferring Stockholder of their intent to
participate and (ii) the satisfaction of any governmental approval or filing
requirements, if any.

         (d) Each participating Investor may effect its participation in any
Transaction Offer hereunder by delivery to the Offeror, or to the Transferring
Stockholder for delivery to the Offeror, of one or more instruments or
certificates, properly endorsed for transfer, representing the Shares it elects
to sell therein. At the time of consummation of the Transaction Offer, the
Offeror shall remit directly to each relevant Investor that portion of the sale
proceeds to which the relevant Investor is entitled by reason of its
participation therein (less any adjustments due to the conversion of any
convertible securities or the exercise of any exercisable securities). No Shares
may be purchased by the Offeror from the Transferring Stockholders or any of
their Permitted Transferees unless the Offeror simultaneously purchases from the
participating Investors all of the Shares that they have elected to sell
pursuant to this Section 2.3.


                                       7
<PAGE>   8


         (e) Any Shares held by a Transferring Stockholder which are the subject
of the Transaction Offer that the Transferring Stockholder desires to sell
following compliance with this Section 2.3 may be sold to the Offeror only
during the period specified in Section 2.2(c) and only on terms no more
favorable to the Transferring Stockholder than those contained in the Offer
Notice. Promptly after such sale, the Transferring Stockholder shall notify the
Company, which in turn shall promptly notify the Investors, of the consummation
thereof and shall furnish such evidence of the completion and time of completion
of such sale and of the terms thereof as may reasonably be requested by a
Majority Interest of the Investors. So long as the Offeror is neither a party
nor an Affiliate of or relative of a party, to this Agreement, such Offeror
shall take the Shares so transferred free and clear of any further restrictions
of this Article II. In the event that the Transaction Offer is not consummated
within the period required by this Section 2.3 or the Offeror fails timely to
remit to each participating Investor its portion of the sale proceeds, the
Transaction Offer shall be deemed to lapse, and any transfers of Shares pursuant
to such Transaction Offer shall be deemed to be in violation of the provisions
of this Agreement unless the Transferring Stockholder once again complies with
the provisions of Section 2.2 and this Section 2.3 hereof with respect to such
Transaction Offer.

     Section 2.4 Contemporaneous Transfers. If two or more Stockholders (or
their Permitted Transferees) propose concurrent transfers which are subject to
this Article II, then the relevant provisions of Sections 2.2 and 2.3, as
applicable, shall apply separately to each such proposed transfer.

     Section 2.5 Investor Transfer and Assignment. No Investor, without the
consent of the Company, shall have the right to Transfer any of its Shares to
any Person prior to the earlier to occur of (i) the second anniversary of the
Closing Date or (ii) the closing of a Qualified Public Offering, except to an
Affiliate of such Investor; provided that any such Transfer prior to a Qualified
Public Offering shall involve at least Two Million (2,000,000) of the Shares
initially purchased by such Investor pursuant to the Purchase Agreement (as
appropriately adjusted for any stock split, combination, reorganization,
recapitalization, reclassification, stock distribution, stock dividend or
similar event). Each Investor shall have the right to assign its rights to any
transferee of its Shares pursuant to this Section 2.5, and any such transferee
shall be deemed within the definition of an "Investor" for purposes of this
Article II and shall comply with the "market stand-off" obligations set forth in
Section 3 of the related Registration Rights Agreement of even date herewith. No
Investor shall Transfer any of its shares of Redeemable Preferred Stock, except
to the same transferee, and simultaneously with a permitted Transfer, of shares
of Preferred Stock on a proportional basis relative to such Investor's initial
holdings of Preferred Stock and Redeemable Preferred Stock.

     Section 2.6 Prohibited Transfers. If any transfer is made or attempted
contrary to the provisions of this Agreement, such purported transfer shall be
void ab initio; the Company and the other parties hereto shall have, in addition
to any other legal or equitable remedies which they may have, the right to
enforce the provisions of this Agreement by actions for specific performance (to
the extent permitted by law); and the Company shall have the right to refuse to
recognize any transferee as one of its Stockholders for any purpose.

                                  ARTICLE III

                               RIGHTS TO PURCHASE

     Notwithstanding anything herein to the contrary, the following provisions
of this Article III shall terminate immediately prior to the closing of a
Qualified Public Offering and shall not apply with respect to any Qualified
Public Offering.

     Section 3.1 Right to Participate in Certain Sales of Additional Securities.
The Company agrees that it will not sell or issue (i) any shares of capital
stock of the Company, (ii) securities convertible into or exchangeable for
capital stock of the Company or (iii) options, warrants or rights carrying any
rights to purchase capital stock of the Company, unless the Company first
submits a written offer to each Investor (collectively, the "Offerees"),
identifying the terms of the proposed sale (including price, number or aggregate
principal amount of securities and all other material terms), and offers to each
Offeree the opportunity to purchase its Pro Rata Allotment (as hereinafter
defined) of the securities (subject to increase for over-allotment if some
Offerees do not fully exercise their rights) on terms and conditions, including
price, not less favorable than those on which the Company proposes to sell such
securities to a third party or parties. Each Offeree's "Pro Rata Allotment" of
such securities shall be based on the ratio (as determined in accordance with
Section 1.3 hereof) which the Shares then owned by it bears to all of the then
issued and outstanding shares of Common Stock (including for this purpose any
shares of Common Stock issuable upon conversion of the Preferred Stock) as of
the date of such written offer. The Company's offer pursuant to this Section 3.1
shall remain open and irrevocable for a period of thirty (30) calendar days, and
the recipients of such offer shall elect to purchase by giving written notice
thereof to the Company within such 30-day period, including therein the maximum
number of shares of capital stock or other securities of the Company which the
Offeree would purchase if other Offerees do not elect to purchase, with the
rights of electing Offerees to purchase such additional shares to be based upon
the relative holdings of Shares of the electing Offerees in the case of
over-subscription. Any securities so offered which are not purchased pursuant to
such offer may be sold by the Company, but only on the terms and conditions set
forth in the initial offer, at any time within 120 calendar days following the
termination of the above-referenced 30-day period but may not be sold to any
other person or on terms and conditions, including price, that are more
favorable to the purchaser than those set forth in such offer or after such
120-day period without renewed compliance with this Section 3.1.

     Notwithstanding the foregoing, the right to purchase granted under this
Article III shall be inapplicable with respect to any (i) of the Excluded Shares
(as defined in the Company's Amended and Restated Articles of Incorporation),
(ii) any shares of Common Stock underlying the option previously granted to
Michael Christian (as appropriately adjusted for any stock split, combination,
reorganization, recapitalization, reclassification, stock distribution, stock
dividend or similar event), (iii) securities issued as a result of any stock
split, stock dividend, reclassification or reorganization or similar event with
respect to the Common Stock, (iv) shares issued as consideration for any
acquisition approved by the Board of Directors, or (v) shares of Common Stock
issued upon conversion of the Preferred Stock.

     Section 3.2 Assignment of Rights. Subject to Section 2.5, the rights of the
Offerees set forth in this Article III are transferable to any transferee of
Shares by Investors.

                                   ARTICLE IV

                              ELECTION OF DIRECTORS

     Section 4.1 Preferred Stock Designees. The parties acknowledge that the
terms of the Preferred Stock provide the holders thereof with certain rights to
elect two members of the Board of Directors, who shall initially be Benjamin H.
Ball and Walter G. Kortschak.

     Section 4.2 Board Composition. Each Investor and each Stockholder
(including, for purposes of this Section 4.2, each Permitted Transferee) agrees
to vote all of its shares of the capital stock of the Company having voting
power (and any other shares over which it exercises voting control), to the
extent it holds such shares of capital stock at the relevant time, in favor of:

         (a) the Board of Directors consisting of not less than five (5) nor
greater than nine (9) members in the aggregate; and

         (b) subject to the termination of the right of the holders of Preferred
Stock to elect directors as set forth in the last sentence of Section A.2.(a) of
Article III of the Company's Amended and Restated Articles of Incorporation, one
(1) individual nominated by TA Associates, Inc. on behalf of the Investors and
one (1) individual nominated by Summit Partners, L.P. on behalf of the
Investors; provided, however, that the right of each of TA Associates, Inc. and
Summit Partners, L.P. to nominate one (1) individual for election to the Board
of Directors shall terminate if either entity (together with its Affiliates)
holds of record less than Two Million (2,000,000) shares of Preferred Stock
(adjusted appropriately for stock splits, stock dividends, recapitalizations and
the like with respect to the Preferred Stock).

     Section 4.3 Removal; Vacancies. Each Investor and each Stockholder agrees
to vote all of his shares of the capital stock of the Company, having voting
power (and any other shares over which he exercises voting control), to the
extent it holds such voting stock at the relevant time, for the removal of any
director upon the request of the Persons then entitled to nominate such director
and for the election to the Board of Directors of a substitute designated by
such party in accordance with the provisions hereof. Each Investor and each
Stockholder further agrees to vote all of his shares of the capital stock of the
Company having voting power (and any other shares over which he or it exercises
voting control) in such manner as shall be necessary or appropriate to ensure
that any vacancy on the Board of Directors occurring for any reason shall be
filled only in accordance with the provisions of this Article IV.

     Section 4.4 Committees of the Board. Prior to the closing of a public
offering of shares of Common Stock or other equity securities of the Company,
the Company, the Investors and the Stockholders agree to cause the Board of
Directors to establish a Compensation Committee (which shall be charged with the

     Section 6.7 Remedies; Severability. It is specifically understood and
agreed that any breach of the provisions of this Agreement by any Person subject

addition to any other legal or equitable remedies which they may have, such

in accordance with and governed by the laws of the State of California (without
giving effect to principles of conflicts of law).

     Section 6.11 Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the respective successors and permitted assigns of
the parties hereto as contemplated herein, and any successor to the Company by
way of merger or otherwise shall specifically agree to be bound by the terms
hereof as a condition of such successor. The rights of the Investors hereunder
shall be assignable to Transferees of their Shares as contemplated herein. This

without such prior written consent, any attempted assignment shall be null and
void.

<PAGE>   15


         (c) hearings before the arbitrator which shall consist of a summary
presentation by each side of not more than three (3) hours; such hearings to

waives, and agrees not to assert, by way of motion, as a defense, or otherwise,
in any such suit, action or proceeding, any claim that it is not subject
personally to the jurisdiction of the above-named courts, that its property is
exempt or immune from attachment or execution (except as protected by applicable
law), that the suit, action or proceeding is brought in an inconvenient forum,
that the venue of the suit, action or proceeding is improper or that this
Agreement or the subject matter hereof may not be enforced in or by such court,
and hereby waives and agrees not to seek any review by any court of any other
jurisdiction which may be called upon to grant an enforcement of the judgment of
any such court. Each of the parties hereto hereby consents to service of process

parties hereto agrees that its or his submission to jurisdiction and its or his
consent to service of process by mail is made for the express benefit of the
other parties hereto. Final judgment against any party hereto in any such
action, suit or proceeding may be enforced in other jurisdictions by suit,
action or proceeding on the judgment, or in any other manner provided by or
pursuant to the laws of such other jurisdiction.

     Section 6.13 Term. This Agreement shall remain in effect until the closing
of a Qualified Public Offering, provided that Article IV shall terminate in any
event on the tenth anniversary of this Agreement if not earlier terminated.
