2.5(b) hereof, it will take all necessary actions to ensure that in such
Majority Sale the Purchaser will have the right to Transfer to the proposed
transferee or acquiring Person (a "Proposed Transferee") a number of shares of
                                   -------------------
Directly Owned Class A Common Stock equal to at least the product (rounded down
to the nearest whole number of shares) of (i) the quotient determined by
dividing (A) the aggregate number of issued and outstanding shares of Directly
Owned Class A Common Stock owned of record by the Purchaser on the closing date
of the Majority Sale by (B) the aggregate number of issued and outstanding
shares of Common Stock on the closing date of the Majority Sale and (ii) the
total number of shares of Common Stock proposed to be directly or indirectly
Transferred to the Proposed Transferee in the Majority Sale, at the same price
per share and upon the same terms and conditions (including, without limitation,
time of payment and form of consideration) as to be paid by and given to the
Transferring Stockholders (such product, the "Co-Sale Amount"); provided,
                                              --------------    --------
however, that for purposes of clause (ii) of this Section 2.5(a), all shares
-------
underlying unexercised Options and Shares Subject to Repurchase shall not be
deemed to be issued and outstanding; provided, further, that subject to
                                     --------  -------
compliance with applicable law, in the event that the Proposed Transferee
notifies the Company that it will require the structure of the transaction
related to the proposed Majority Sale to be treated as a recapitalization for
financial accounting purposes and that it will require the Company to no longer
be subject to the reporting requirements or Section 14 of the Exchange Act after
the closing date of the proposed Majority Sale, then, solely to the extent
deemed necessary by the Proposed Transferee to satisfy such requirements, the
Proposed Transferee may pay to the Purchaser consideration in the Majority Sale
with respect to the shares of Directly Owned Class A Common Stock owned by him
or her that differs from the form of consideration paid to one or more of the
Transferring Stockholders.

               (b)  To the extent permitted under applicable law, in order to be
entitled to the right set forth in Section 2.5(a) hereto, the Purchaser must
agree to (i) make representations and warranties (and provide related
indemnification) as to his or her individual Ownership of Directly Owned Class A
Common Stock (and then only to the same extent such representations and
warranties are severally given by the Transferring Stockholders with respect to
their several Ownership of Common Stock), and (ii) agree to pay his or her pro
rata share (based on the number of shares Transferred by each Stockholder in
such Majority Sale) of any liability arising out of any representations,
warranties, covenants or agreements of the Transferring Stockholders that
survive the closing of such Majority Sale and do not relate to Ownership of
Common Stock. If the Purchaser is a holder of Common Stock Equivalents and
wishes to participate in a sale of Common Stock pursuant to Section 2.5(a), the
Purchaser shall convert or exercise or exchange such number of Common Stock
Equivalents into or for Directly Owned Class A Common Stock as may be required
therefor on or prior to the closing date of the Majority Sale.

               (c)  Subject to the Purchaser's compliance with the terms of
Section 2.5(b) hereto, if and to the extent the Proposed Transferee fails to
purchase from the Purchaser on the closing date of the Majority Sale any portion
of the Co-Sale Amount that Purchaser has properly exercised his or her right to
Transfer pursuant to this Section 2.5, then the Company agrees to purchase from
the Purchaser on the closing date of the Majority Sale a number of shares of
Directly Owned Class A Common Stock beneficially owned by the Purchaser such
that, after such purchase by the Company, the Purchaser shall have Transferred
to the Company and the Proposed Transferee, to the extent applicable, an amount
of shares of Directly Owned Class A Common Stock equal to such portion of the
Co-Sale Amount that Purchaser has properly exercised his or her right to
Transfer pursuant to this Section 2.5. The Purchaser agrees that this Section
2.5(c) shall be the sole and exclusive remedy of the Purchaser in the event that
the Proposed Transferee fails to purchase from the Purchaser on the closing date
of the Majority Sale any portion of the Co-Sale Amount that Purchaser has
properly exercised his or her right to Transfer pursuant to this Section 2.5.

          2.6. Public Offerings.  The provisions of Section 2.5 and Section 2.7
          ---------------------
shall not be applicable to offers and sales of Securities in a Public Offering.

          2.7. Required Sale Right.
          ------------------------

               (a)  Prior to a Qualified Initial Public Offering, to the extent
permitted under applicable law, if one or more Stockholders (in such capacity,
the "Requiring Parties") agree to a Transfer of Common Stock constituting a
     -----------------
Majority Sale to any Non-RCBA Strategic Party, then the Purchaser hereby agrees
that, if requested by the Requiring Parties, he or she will Transfer to such
transferee or acquiring Person (the "Purchasing Party") on the same terms and
                                     ----------------
conditions (including, without limitation, time of payment and form of
consideration, but subject to Section 2.7(b)) as to be paid and given to the
Requiring Parties, the same portion (as determined by the immediately succeeding
sentence) of the Purchaser's Directly Owned Class A Common Stock as is being
Transferred by the Requiring Parties; provided, however, that subject to
                                      --------  -------
compliance with applicable law, in the event that the Purchasing Party notifies
the Company that it will require the structure of the transaction related to the
proposed Majority Sale to be treated as a recapitalization for financial
accounting purposes and that it will require the Company to no longer be subject
to the reporting requirements or Section 14 of the Exchange Act after the
closing date of the proposed Majority Sale, then, solely to the extent deemed
necessary by the Purchasing Party to satisfy such requirements, the Purchasing
Party may pay to the Purchaser consideration in the Majority Sale with respect
to the shares of Directly Owned Class A Common Stock owned by him or her that
differs from the form of consideration paid to one or more of the Requiring
Parties. The Purchaser can be required to Transfer pursuant to this Section 2.7
that number of shares of Directly Owned Class A Common Stock equal to the
product obtained by multiplying (i) a fraction, (a) the numerator of which is
the aggregate number of issued and outstanding shares of Directly Owned Class A
Common Stock to be Transferred by the Requiring Parties and (b) the denominator
of which is the aggregate number of issued and outstanding shares of Common
Stock owned by the Requiring Parties at the time of the Transfer by (ii) the
aggregate number of issued and outstanding shares of Directly Owned Class A
Common Stock owned by the Purchaser.

               (b)  To exercise the right set forth in Section 2.7(a) hereto,
the Requiring Parties must give written notice (the "Required Sale Notice") to

prior to such Transfer. The Required Sale Notice will set forth the number of

Party, the proposed amount and form of consideration and the other terms and
conditions of the proposed Majority Sale. In connection with any such Transfer,
the Purchaser shall be obligated only to (i) make representations and warranties
(and provide related indemnification) as to his or her individual Ownership of
Directly Owned Class A Common Stock (and then only to the same extent such
representations and warranties are severally given by the Requiring Parties with
respect to their several Ownership of Common Stock), and (ii) agree to pay his
or her pro rata share (based on the number of shares Transferred by each
Stockholder in such Majority Sale) of any liability arising out of any
representations, warranties, covenants or agreements of the Requiring Parties
that survive the closing of such Majority Sale and do not relate to Ownership of
Common Stock. If the Transfer referred to in the Required Sale Notice is not
consummated within 120 days from the date of the Required Sale Notice, the
Requiring Parties must deliver another Required Sale Notice in order to exercise
their rights under this Section 2.7 with respect to such Transfer or any other
Transfer.

               (c)  The Company and the Purchaser each agree that any and all
Requiring Parties shall be third party beneficiaries of this Section 2.7.

          2.8. Company Right of Repurchase on Unvested Shares.
          ---------------------------------------------------

               (a)  If the Purchaser's employment with the Company and its
Subsidiaries is terminated for any reason (including as a result of the death or
disability of the Purchaser), the Purchaser shall be required to offer his or
her Shares Subject to Repurchase for sale to the Company and accordingly the
Company or its designated assignee shall have the option to purchase all or any
portion (at the Company's option) of the Shares Subject to Repurchase held by
the Purchaser and the Purchaser's Permitted Transferees by providing written
notice of the election (including the number of Shares Subject to Repurchase to
be purchased, the identity of the purchaser, the purchase price for the Shares
Subject to Repurchase as determined pursuant to Section 2.8(b) hereto and, if
applicable, the net purchase price for the Securities to be paid to the
Purchaser pursuant to Section 2.8(c) hereto) to the Purchaser and the Permitted
Transferees (a "Repurchase Notice") no later than 180 days after termination of
                -----------------
Purchaser's employment with the Company and its Subsidiaries.

               (b)  If the Purchaser's employment with the Company and its
Subsidiaries is terminated by the applicable employer for Cause or the
Purchaser's employment with the Company and its Subsidiaries is voluntarily
terminated by the Purchaser other than for Good Reason, then the purchase price
per share for the Shares Subject to Repurchase pursuant to Section 2.8(a) or
shares to be sold pursuant to Section 2.9, as applicable, will be the lower of
Cost and Fair Market Value on the date of the Purchaser's termination of
employment. If the Purchaser's employment with the Company and its Subsidiaries
is terminated for any reason other than under circumstances in which the
immediately preceding sentence applies, then the purchase price per share for
the Shares Subject to Repurchase pursuant to Section 2.8(a) or shares to be sold
pursuant to Section 2.9, as applicable, will be the Fair Market Value on the
date

of Purchaser's termination of employment. The purchase price determined pursuant
to this Section 2.8(b) is referred to as the "Repurchase Price."
                                              ----------------

               (c)  The completion of the purchase pursuant to Section 2.8(a)
shall take place at the principal office of the Company on or prior to the
thirtieth (30th) day after the giving of the Repurchase Notice. The repurchase
price for the Shares Subject to Repurchase shall be paid by delivery to the
Purchaser or Permitted Transferee of a certified bank check or checks in the
appropriate amount payable to the order of the Purchaser or Permitted
Transferee; provided, however, that if the Purchaser previously has executed and
            --------  -------
delivered a Note to the Company, such repurchase price shall be net of the
concurrent prepayment to the Company of the aggregate accrued and unpaid
interest and unpaid principal thereon pursuant to Section 3.3 hereto.

          2.9. Sale Right.
          ---------------

               (a)  In the event that (i) the Purchaser's employment with the
Company and its Subsidiaries has been terminated for any reason (including as a
result of the death or disability of the Purchaser) and (ii) neither the Company
nor its designee has delivered a Repurchase Notice to the Purchaser at least 20
days prior to the Note Repayment Date, then the Purchaser shall have the option
to sell to the Company, and the Company shall be obligated to purchase, on one
occasion from the Purchaser, a portion of the shares of Directly Owned Class A
Common Stock held by Purchaser with an aggregate Repurchase Price on the date of
the Purchaser's termination of employment equal to the Note Repayment Amount
(the "Note Repayment Shares"); provided, however, that if the Note Repayment
      ---------------------    --------  -------
Amount exceeds the aggregate Repurchase Price of all shares of Directly Owned
Class A Common Stock owned by the Purchaser on the date the Purchaser's
employment is terminated, then the Company shall only be required to purchase
such shares pursuant to this Section 2.9 and the remaining portion of the Note
Repayment Amount shall remain payable under the terms of the Note; provided,
                                                                   --------
further, that the first shares of Directly Owned Class A Common Stock sold by
-------
the Purchaser must be shares other than Shares Subject to Repurchase until the
Purchaser owns no more of such shares, and then the Shares Subject to Repurchase
until the Purchaser owns no more of such shares. The purchase price per share
for such Note Repayment Shares will be the Repurchase Price and shall be
determined as of the date of the Purchaser's termination of employment.

               (b)  In order to exercise the right set forth in Section 2.9(a)
hereto, the Purchaser shall be required to deliver a written notice of his or
her election to the Company (a "Sale Notice") no later than 10 days prior to the
                                -----------
Note Repayment Date.

               (c)  The completion of the purchase pursuant to Section 2.9(a)
shall take place at the principal office of the Company on the Note Repayment
Date. If the Note Repayment Amount is less than or equal to the aggregate
Repurchase Price of all of the shares of Directly Owned Class A Common Stock
owned by the Purchaser on the date the Purchaser's employment is terminated,
then the purchase pursuant to Section 2.9(a) hereto shall be completed on such
Note Repayment Date by the Company's cancellation of the Note and the delivery
of such cancelled Note to the Purchaser. If the Note Repayment Amount exceeds
the aggregate Repurchase Price of all of the shares of Directly Owned Class A
Common Stock owned by the Purchaser on the date the Purchaser's employment is
terminated, then the purchase

                                                                              12

pursuant to Section 2.9(a) hereto shall be completed on such Note Repayment Date
by the Company's reduction of the aggregate outstanding principal amount of the
Note to reflect the repayment of a portion thereof equal to the aggregate
Repurchase Price of all of the shares of Directly Owned Class A Common Stock
owned by the Purchaser on the date the Purchaser's employment was terminated
(with the remaining outstanding principal amount of the Note subject to
repayment upon the terms set forth in the Note).

by the representative of the underwriters of Common Stock (or other securities)
of the Company not to exceed one hundred eighty (180) days following the

the foregoing shall not apply to information which is not unique to the Company
or which is generally known to the industry or the public other than as a result
of the Purchaser's breach of this covenant or the wrongful acts of others who
were under confidentiality obligations as to the item or items involved. Except
as required by law, the Purchaser will not disclose to anyone, other than
Purchaser's immediate family and legal or financial advisors, the existence or

Repurchase by the Purchaser shall be void and of no effect unless and until the
Net Proceeds (as defined below) directly or indirectly received by the Purchaser
in respect thereof shall have been applied to the prepayment, first, of the

secured pursuant to the Pledge Agreement to the same extent as would have been
the case had such transfer not occurred and (ii) the Purchaser remains liable
for all indebtedness outstanding under the Note. The term "Net Proceeds" shall
