<PAGE>

Company or such agent may hereafter designate in writing to the Holder), with
the purchase form annexed hereto (the "Purchase Form") duly executed and
accompanied by cash or a certified or official bank check drawn to the order of
"REPLIGEN CORPORATION" (or its successor in interest, if any) in the amount of
the Exercise Price, multiplied by the number of Warrant Shares specified in such
Purchase Form. If this Warrant should be exercised in part only, the Company or

evidencing the right of the Holder thereof to purchase the balance of the
Warrant Shares purchasable hereunder. Upon receipt by the Company during the
Exercise Period of this Warrant and such Purchase Form in proper form for
exercise, together with proper payment of the Exercise Price at its principal
office, or by its agent at its office, the Holder shall be deemed to be the
holder of record of the number of Warrant Shares specified in such Purchase
Form; PROVIDED, HOWEVER, that if the date of such receipt by the Company or its
agent is a date on which the stock transfer books of the Company are closed,
such person shall be deemed to have become the record holder of such shares on
the next business day on which the stock transfer books of the Company are open.
The Company shall pay any and all documentary, stamp or similar issue or
transfer taxes payable in respect of the issue or delivery of such Warrant
Shares. Any Warrant issued upon partial exercise of this Warrant pursuant to
this Section 2 shall be dated the date of this Warrant.

3.       RESERVATION OF SHARES. The Company agrees that at all times it will
keep reserved solely for issuance and delivery pursuant to the Warrants the
number of shares of its Common Stock that are or would be issuable from time to
time upon exercise of this Warrant. All such shares shall be duly authorized
and, when issued upon such exercise, shall be validly issued, fully paid and
nonassessable, free and clear of all liens, security interests, charges and
other encumbrances or restrictions on sale and free of all preemptive rights.
Before taking any action that would cause an adjustment pursuant to Section 8
hereof reducing the Exercise Price below the then par value (if any) of the
Warrant Shares issuable upon exercise of this Warrant, the Company will take any
corporate action that may, in the opinion of its counsel, be necessary in order
that the Company may validly and legally issue fully paid and nonassessable
Warrant Shares at the Exercise Price as so adjusted.

4.       WARRANT SHARE REGISTRATION RIGHTS.

         (a)  The Company will use commercially reasonable efforts to (i)
prepare and file with the Securities and Exchange Commission (the "SEC") under
the Act a registration statement with respect to the Warrant Shares issuable
upon exercise of this Warrant, (ii) cause such registration statement to become
effective under the Act within 45 days from the date hereof and remain effective
under the Act during the Exercise Period while any of such Warrants are
outstanding and (iii) register or qualify such Warrant Shares under the
securities or Blue Sky laws of each jurisdiction within the United States in
which such registration or qualification is necessary in connection with the
issuance and delivery of such Warrant Shares to the Holders of the Warrants.

         (b)  In connection with the registration and qualification referred to
in subsection (a) of this Section 4, the Company covenants and agrees:

              (i)       to use reasonable commercial efforts, to prepare and
         file with the SEC such amendments and supplements to such registration
         statement and the prospectus used

                                       3

<PAGE>

         in connection therewith as may be necessary to keep such registration
         statement effective throughout the Exercise Period;

              (ii)      to use reasonable commercial efforts, to take such
         action as may be necessary or desirable to maintain the registration
         and qualification of the Warrant Shares under the securities or Blue
         Sky laws of the jurisdictions referred to in subsection (a) of this
         Section 4; and

              (iii)     to pay all expenses incurred by the Company in complying
         with subsection (a) of this Section 4 and this subsection (b),
         including (A) all registration and filing fees, (B) all printing
         expenses, (C) all fees and disbursements of its counsel and independent
         public accountants and (D) all Blue Sky fees and expenses (including
         fees and disbursements of counsel).

5.       EXCHANGE, TRANSFER OR ASSIGNMENT OF WARRANT.

         (a)  If the Holder has received an opinion of counsel satisfactory to
the Company that this Warrant may be freely sold or transferred without
registration under the Act, this Warrant may be, at the option of the Holder,
and upon presentation and surrender hereof to the Company or at the office of
its stock transfer agent, (i) exchanged for other Warrants of different
denominations, entitling the Holder or Holders thereof to purchase in the
aggregate the same number of Warrant Shares at the Exercise Price or (ii) if
delivered together with a written notice specifying the denominations in which
new Warrants are to be issued and signed by the Holder hereof, divided or
combined with other Warrants that carry the same rights.

         (b)  If the Holder has received an opinion of counsel satisfactory to
the Company that this Warrant may be freely sold or transferred without
registration under the Act, this Warrant may be assigned, at the option of
Holder, upon surrender of this Warrant to the Company or at the office of its
stock transfer agent, with the Warrant Assignment Form annexed hereto duly
executed and accompanied by funds sufficient to pay any transfer tax. The
Company shall execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees named in such instrument of assignment and, if the
Holder's entire Interest is not being transferred or assigned, in the name of
the Holder, and this Warrant shall promptly be canceled.

         (c)  Any transfer or exchange of this Warrant shall be without charge
to the Holder and any new Warrant or Warrants issued pursuant to this Section 5
shall be dated the date hereof.

6.       LOST, MUTILATED OR MISSING WARRANT. Upon receipt by the Company or its
agent of evidence satisfactory to it of the loss, theft or destruction of this
Warrant, and of satisfactory indemnification, and upon surrender and
cancellation of this Warrant if mutilated, the Company or its agent shall
execute and deliver a Warrant of like tenor and date in exchange for this
Warrant.

7.       RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or in
equity, and the rights of the Holder are limited to those expressed in this
Warrant.

8.       ANTI-DILUTION. (a) If the Company shall fix or have fixed a record date
at any time after the date hereof and before the expiration of the Exercise
Period for:

              (i)       STOCK DIVIDENDS, SUBDIVISIONS, COMBINATIONS,
         RECLASSIFICATIONS, ETC. (A) The declaration of a dividend or
         distribution on the Common Stock (or other securities deliverable
         hereunder) payable in shares of capital stock (whether shares of Common
         Stock or of capital stock of any other class), (ii) the subdivision of
         shares of the Common Stock into a greater number of shares, (iii) the
         combination of the Common Stock into a smaller number of shares or (iv)
         the issuance of any shares of its capital stock by reclassification of
         the Common Stock in connection with a consolidation or merger with a
         subsidiary of the Company in which the Company is the continuing
         corporation, then, in any such event, the Holder shall be entitled to
         receive the aggregate number and kind of shares which, if the Warrant
         had been exercised immediately prior to such record date, he would have
         been entitled to receive by virtue of such dividend, distribution,
         subdivision, combination or reclassification, and the Exercise Price
         shall be appropriately adjusted. Such adjustment shall be made
         successively whenever any event listed above shall occur.

              (ii)      ISSUANCE AT LESS THAN CURRENT MARKET PRICE. The issuance
         of Common Stock (or other securities deliverable hereunder), rights,
         options (excluding options issued in connection with an employee stock
         option or similar plan) or warrants to all holders of Common Stock (or
         such other securities deliverable hereunder) entitling them to
         subscribe for or purchase Common Stock (or such other securities) at a
         price per share or having a conversion price per share less than the
         Closing Price on such record date (excluding rights or warrants that
         are not immediately exercisable and for which provision is made for the
         Holder to receive comparable rights or warrants), then the number of
         Warrant Shares to be received hereunder after such record date shall be
         determined by multiplying the number of shares receivable hereunder
         immediately prior to such record date by a fraction, the denominator of
         which shall be the number of shares of Common Stock (or such other
         securities deliverable hereunder) outstanding on such record date plus
         the number of shares of Common Stock (or such other securities) that
         the aggregate offering price of the total number of shares so offered
         for subscription or purchase would purchase at such Closing Price, and
         the numerator of which shall be the number of shares of Common Stock
         (or such other securities) outstanding on such record date plus the
         number of additional shares of Common Stock (or such other securities)
         offered for subscription or purchase, and the Exercise Price shall be
         appropriately adjusted. Shares of Common Stock owned by or held for the
         account of the Company or any subsidiary of the Company on such record
         date shall not be deemed outstanding for the purpose of any such
         computation. Such adjustment shall become effective immediately after
         such record date. Such adjustment shall be made successively whenever
         any such event shall occur. If such rights or warrants are not so
         issued, the number of Warrant Shares receivable hereunder shall again
         be adjusted to be the number that would have been in effect had such
         record date not been fixed. On the expiration of such rights or
         warrants the number of Warrant Shares receivable hereunder shall be
         adjusted to be the number that would have obtained had the adjustment
         made upon the issuance of such rights or warrants been made upon the
         basis of the issuance of only the number of shares of Common Stock (or
         such other securities deliverable hereunder) actually issued upon the
         exercise of such rights or warrants. In any case in which this

                                       5

<PAGE>

         subsection (ii) shall require that an adjustment in the number of
         shares receivable hereunder or the Exercise Price be made effective as
         of a record date for a specified event, the Company may elect to defer
         until the occurrence of such event issuing to the Holder of any Warrant
         exercised after such record date the number of Warrant Shares, if any,
         issuable upon such exercise over and above the number of Warrant
         Shares, if any, issuable upon such exercise on the basis of the
         Exercise Price in effect prior to such adjustment; PROVIDED, HOWEVER,
         that the Company shall deliver to such Holder a due bill or other
         appropriate instrument evidencing such Holder's right to receive such
         additional Warrant Shares upon the occurrence of the event requiring
         such adjustments.

              (iii)     DISTRIBUTION OF SUBSCRIPTION RIGHTS, WARRANTS,
         EVIDENCES OF INDEBTEDNESS OR ASSETS. The making of a distribution to
         all holders of Common Stock (or other securities deliverable
         hereunder) (including any such distribution to be made in connection
         with a consolidation or merger in which the Company is to be the
         continuing corporation) of (A) any shares of capital stock of the
         Company (other than Common Stock), (B) subscription rights or
         warrants (excluding those for which adjustment is provided in
         subsection 8(a)(ii) above and excluding those that are not
         immediately exercisable and for which provision is made for the
         Holder to receive comparable subscription rights or warrants) or (C)
         evidences of its indebtedness or assets (excluding (x) dividends
         paid in or distributions of the Company's capital stock for which
         the number of Warrant Shares receivable hereunder shall have been
         adjusted pursuant to paragraph 8(a)(i) and (y) cash dividends or
         distributions payable out of earnings or surplus not in excess of
         10% of the average Closing Price for the thirty trading days prior
         to the fifth day before the date of declaration) any of the
         foregoing being hereinafter in this paragraph (iii) called the
         "Securities"), then in each such case (unless the Company elects to
         reserve shares or other units of such Securities for distribution to
         each Holder upon exercise of the Warrant so that, in addition to the
         shares of the Common Stock (or other securities deliverable
         hereunder) to which each Holder is entitled, each Holder will
         receive upon such exercise the amount and kind of such Securities
         which such Holder would have received if the Company had,
         immediately prior to the record date for the distribution of the
         Securities, exercised the Warrant) the number of Warrant Shares
         receivable hereunder after such record date shall be determined by
         multiplying the number of Warrant Shares receivable hereunder
         immediately prior to such record date by a fraction, the denominator
         of which shall be the Closing Price on the trading day immediately
         prior to the date the Common Stock (or such other securities
         deliverable hereunder) trades without the right to receive such
         Securities, less the fair market value (as determined in the
         reasonable judgment of the Board of Directors of the Company and
         described in a statement mailed by certified mail to the Holder) of
         the portion of the assets or evidences of indebtedness so to be
         distributed to a holder of one share of the Common Stock or of such
         subscription rights or warrants applicable to one share of the
         Common Stock, and the numerator of which shall be the Closing Price
         of the Common Stock on such trading date; and the Exercise Price
         shall be appropriately adjusted. Such adjustment shall become
         effective immediately after such record date and shall be made
         successively whenever such a record date is fixed. If such
         distribution is not so made, the number of Warrant Shares receivable
         hereunder shall again be adjusted to be the number that was in
         effect immediately prior to such record date. In any case in which
         this paragraph (iii) shall require that an adjustment in the number
         of Warrant Shares

                                       6

<PAGE>

    receivable hereunder or the Exercise Price be made effective as of a
    record date for a specified event, the Company may elect to defer until
    the occurrence of such event issuing to the Holder of any Warrant
    exercised after such record date the number of Warrant Shares, if any,
    issuable upon such exercise over and above the number of Warrant Shares,
    if any, issuable upon such exercise on the basis of the Exercise Price in
    effect prior to such adjustment; PROVIDED, HOWEVER, that the Company
    shall deliver to such Holder a due bill or other appropriate instrument
    evidencing such Holder's right to receive such additional Warrant Shares
    upon the occurrence of the event requiring such adjustments.

         (b)  REORGANIZATION EVENT.

              (i)       In case of any Reorganization Event the Company shall,
    as a condition precedent to the consummation of the transaction
    constituting, or announced as, such Reorganization Event, cause effective
    provisions to be made so that the Holder shall have the right immediately
    thereafter, by exercising this Warrant, to receive the aggregate amount and
    kind of shares of stock and other securities and property that were
    receivable upon such Reorganization Event by a holder of the number of
    shares' of Common Stock that would have been received immediately prior to
    such Reorganization Event upon exercise of this Warrant. Any such provision
    shall include provision for adjustments in respect of such shares of stock
    and other securities and property that shall be as nearly equivalent as may
    be practicable to the adjustments provided for in Section 8(a). The
    foregoing provisions of this Section 8(b) shall similarly apply to
    successive Reorganization Events.

              (ii)      The Company shall, at least twenty days before earliest
    of (1) the date on which a Reorganization Event occurs or (2) the date on
    which the Company shall agree to effect a Reorganization Event (PROVIDED
    that if approval of the shareholders of the Company is required in
    connection with such Reorganization Event then on the date of such approval
    and PROVIDED FURTHER that if such Reorganization Event was beyond the
    control of the Company, and the Company did not have knowledge twenty days
    before the date of such Reorganization Event, as soon as practicable
    thereafter), cause to be mailed to the Holder a notice describing in
    reasonable detail such Reorganization Event and informing the Holder of his
    or her rights pursuant to Section 8(b)(i) above.

         (c)  FRACTIONAL SHARES. No fractional shares of Common Stock (or other
securities deliverable hereunder) or scrip shall be issued to any Holder in
connection with the exercise of this Warrant. Instead of any fractional share of
Common Stock (or other securities deliverable hereunder) that would otherwise be
issuable to such Holder, the Company shall pay to such Holder a cash adjustment
in respect of such fractional interest in an amount equal to such fractional
interest multiplied by the then current Closing Price per share of Common Stock
(or other securities deliverable hereunder).

         (d)  CARRYOVER. Notwithstanding any other provision of this Section 8,
no adjustment shall be made to the number of shares of Common Stock (or other
securities deliverable hereunder) to be delivered to each Holder (or to the
Exercise Price) if such adjustment would represent less than one percent of the
number of shares to be so delivered, but any such

                                       7

<PAGE>

adjustment shall be carried forward and shall be made at the time and together
with the next subsequent adjustment which, together with any adjustments so
carried forward, shall amount to one percent or more of the number of shares to
be so delivered.

         (e)  NOTICES OF CERTAIN EVENTS. If at any time after the date hereof
and before the expiration of the Exercise Period:

              (i)       the Company authorizes the issuance to all holders of
    its Common Stock of (A) rights or warrants to subscribe for or purchase
    shares of its Common Stock or (B) any other subscription rights or warrants;
    or

              (ii)      the Company authorizes the distribution to all holders
    of its Common Stock of evidences of its indebtedness or assets (other than
    cash dividends or distributions excluded from the operation of paragraph
    8(a)(iii); or

              (iii)     there shall be any capital reorganization of the Company
    or reclassification of the Common Stock (other than a change in par value of
    the Common Stock or an increase in the authorized capital stock of the
    Company not involving the issuance of any shares thereof) or any
    consolidation or merger to which the Company is a party (other than a
    consolidation or merger with a subsidiary in which the Company is the
    continuing corporation and that does not result in any reclassification or
    change in the Common Stock outstanding) or a conveyance or transfer of all
    or substantially all of the properties and assets of the Company;

              (iv)      there shall be any voluntary or involuntary dissolution,
    liquidation or winding-up of the Company; or

              (v)       there shall be any other event that would result in an
    adjustment pursuant to this Section 8 in the Exercise Price or the number of
    Warrant Shares that may be purchased upon the exercise hereof;

any such reorganization, reclassification, consolidation, merger, conveyance,
transfer, dissolution, liquidation or winding-up is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record will be entitled to exchange their shares of Common Stock for
securities or other property, if any, deliverable upon such reorganization,

Board of Directors it would be detrimental to the Company and its stockholders
for such registration statement to be filed at the date filing would be required
and it is therefore essential to defer the filing of such registration
statement, the Company shall have an additional period of not more than ninety
(90) days after the expiration of the initial 60-day period within which to file
such registration statement; provided, however, that the Company may not utilize
this right more than once in any twelve month period.

                           (b) UNDERWRITING. If the Requesting Holders intend to
distribute the Registrable Securities covered by their request by means of an
underwriting, such Requesting Holders shall so advise the Company as part of
their request made pursuant to this Section 1.2 and the Company shall include
such information in the written notice referred to in Section 1.2(a)(i). In such
event, the underwriter shall be selected by mutual agreement of the Company and
the requesting Holder. The right of any other Holder to include its Registrable
Securities in the registration made pursuant to this Section 1.2 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting (unless
otherwise mutually agreed by the requesting Holder and such other Holder) to the
extent provided herein. The Company shall (together with all Holders proposing
to distribute their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters.
Notwithstanding any other provision of this Section 1.2, if the underwriter
advises the Requesting Holders and the Company in writing that marketing factors
require a limitation of the number of shares to be underwritten, the Company
shall so advise all Holders of Registrable Securities which would otherwise be
underwritten pursuant hereto, and the number of shares of Registrable Securities
that may be included in the registration and underwriting shall be allocated
among all Holders thereof in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by such Holders; PROVIDED,
HOWEVER, that Registrable Securities held by Holders other than Sony,
Convergence, funds advised by Seligman, the Holders of the Series C Shares, the
holders of the Series C-1 Shares, and the Holders of the Series C-2 Shares shall
be excluded first pro rata from the registration and PROVIDED, FURTHER, that the
Registrable Securities held by Holders who were not Requesting Holders shall be
excluded next from the registration so that the Requesting Holders shall be
entitled to include their Registrable Securities in the registration to the
maximum extent permitted by the underwriter, and PROVIDED, FURTHER, that any
further cutbacks shall be made among the Requesting Holders in proportion to the
number of Registrable Securities being offered by such Requesting Holders. If
any Holder of Registrable Securities disapproves of the terms of the
underwriting, such Holder may elect to withdraw therefrom by written notice to
the Company, the underwriter and the Holder requesting registration. Any
Registrable Securities which are excluded from the underwriting by reason of the
underwriter's marketing limitation or withdrawn from such underwriting shall be
withdrawn from such registration.

                           (c) COMPANY SHARES. If the managing underwriter has
not limited the number of Registrable Securities to be underwritten pursuant to
subsection (b) above, the

                                       5
<PAGE>

Company may include securities for its own account or for the account of others
in such registration if the managing underwriter so agrees and if the number of
Registrable Securities which would otherwise have been included in such
registration and underwriting will not thereby be limited.

                  1.3 COMPANY REGISTRATION.

                           (a) REGISTRATION. If at any time or from time to
time, the Company shall determine to register any of its securities, for its own
account or the account of any of its stockholders, other than a registration on
S-8 relating solely to employee stock option or purchase plans, or a
registration relating solely to an SEC Rule 145 transaction, a registration in
which the only stock being registered is Common Stock issuable upon conversion
of debt securities which are also being registered or a registration on any
other form (other than Form S-1, S-2, S-3, SB-1 or SB-2, or their successor
forms) or any successor to such forms, which does not include substantially the
same information as would be required to be included in a registration statement
covering the sale of Registrable Securities, the Company will:

                                (i) promptly give to each Holder of at least
300,000 shares of Registrable Securities issued or issuable in connection with
the Versity Merger Agreement or upon conversion of the Company's Series B
Preferred Stock or Series B-1 Preferred Stock, or in the case of Sony, both
aggregated together (as adjusted for stock splits, dividends, combinations or
the like), and each holder of Series C Shares, Series C-1 Shares, or Series C-2
Shares (each a "Qualified Holder"), written notice thereof; and

                                (ii) include in such registration (and
compliance), and in any underwriting involved therein, all the Registrable
Securities specified in a written request or requests, made within 20 days after
receipt of such written notice from the Company, by any Qualified Holder, except
as set forth in Section 1.3(b) below.

                           (b) UNDERWRITING. If the registration of which the
Company gives notice is for a registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to Section 1.3(a)(i). In such event the right of any
Holder to registration pursuant to this Section 1.3 shall be conditioned upon
such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting to the extent provided
herein. All Holders proposing to distribute their securities through such
underwriting shall (together with the Company and the other stockholders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company. Notwithstanding any other
provision of this Section 1.3, if the underwriter determines that marketing
factors require a limitation of the number of shares to be underwritten, and (i)
if such registration is the first registered offering of the sale of the
Company's securities to the general public, the underwriter may limit the number
of Registrable Securities to be included in the registration and underwriting on
a pro rata basis according to the number of shares of Registrable Securities
held by such Holder as a percentage of the total number of Registrable
Securities, or may exclude Registrable Securities entirely from such
registration and underwriting, PROVIDED that all securities other than
Registrable Securities are first excluded from such registration; or (ii) if
such registration is other than the first registered offering of the sale of

                                       6
<PAGE>

the Company's securities to the general public, the underwriter may limit the
amount of Registrable Securities to be included in the registration and
underwriting by the Company's stockholders on a pro rata basis according to the
number of shares of Registrable Securities held by such Holder as a percentage
of the total number of Registrable Securities; PROVIDED, HOWEVER, the number of
Registrable Securities to be included in such registration and underwriting
under this Section 1.3(b) shall not be reduced to less than thirty percent (30%)
of the aggregate securities included in such registration without the prior
consent of the Holders holding at least a majority of the Registrable Securities
requested to be included in such registration and underwriting. The Company
shall so advise all Holders of Registrable Securities which would otherwise be
registered and underwritten pursuant hereto. If any Holder disapproves of the
terms of the any such underwriting, he may elect to withdraw therefrom by
written notice to the Company and the underwriter. Any Registrable Securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration.

         For any selling Holder which is a partnership or corporation, the
partners, retired partners and stockholders of such Holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing persons shall be deemed to be a single selling
Holder such that any pro rata reduction with respect to such selling Holder
shall be based upon the aggregate amount of Registrable Securities owned by all
entities and individuals included in such selling Holder.

                  1.4 FORM S-3. In addition to the rights and obligations set
forth in Section 1.2 and 1.3 above, if the Company shall receive from Initiating
Holders a written request that the Company file a registration statement on Form
S-3 (or any successor to Form S-3) for a public offering of shares of
Registrable Securities and any related qualification or compliance, the
reasonably anticipated aggregate price to the public of which (net of
underwriting discounts and commissions) would equal at least $1,000,000 and the
Company is then a registrant entitled to use Form S-3 to register the shares for
such an offering, the Company will give prompt written notice of the proposed
registration, qualification and compliance to all other Holders and shall file
such registration statement within sixty (60) days after receipt of the request
from the Initiating Holders and shall use its best efforts to cause such shares
to be registered for the offering as may be requested in writing within fifteen
(15) days after receipt of such written notice from the Company as soon as
practicable on Form S-3 (or any successor form to Form S-3); PROVIDED, HOWEVER,
the Company shall not be required to effect a registration pursuant to this
Section 1.4:

                           (a) in any particular jurisdiction in which the
Company would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                           (b) if the Company, within ten (10) days of the
receipt of the request of the Initiating Holders, gives notice of its bona fide
intention to effect the filing of a registration statement with the SEC within
sixty (60) days of receipt of such request (other than with respect to a
registration statement relating to a Rule 145 transaction, an offering solely to
employees or any other registration which is not appropriate for the
registration of Registrable Securities);

                                       7
<PAGE>

                           (c) during the period starting with the date of
filing of, and ending on a date one hundred eighty (180) days following the
effective date of, a registration statement pursuant to Sections 1.2 or 1.3,
provided that the Company is actively employing in good faith all reasonable
efforts to cause such registration statement to become effective and further
provided that no other person or entity could require the Company to file a
registration statement in such period;

                           (d) if the Company has effected two (2) registrations
pursuant to this Section 1.4 within the 12-month period prior to the date of
such request; or

                           (e) if the Company shall furnish to such Initiating
Holders a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors of the Company, it would be
detrimental to the Company and its stockholders for such registration statement
to be filed on or before the date filing would be required and it is therefore
essential to defer the filing of such registration statement, in which case the
Company shall have the right to defer such filing for a period of not more than
ninety (90) days after receipt of the request of the Initiating Holders under
this Section 1.4, provided that the Company may not defer such filing pursuant
to this Section 1.4 more than once in any 12-month period.

         In the event such Initiating Holders propose to offer the shares of
Registrable Securities pursuant to this Section 1.4 by means of an underwriting,
the proposed underwriters shall be selected by the Company and shall be
reasonably acceptable to a majority in interest of the Initiating Holders. The
Company shall give written notice to all Holders of the receipt of a request for
registration pursuant to this Section 1.4 and shall provide a reasonable
opportunity for other Holders to participate in the registration, provided that
if the registration is for an underwritten offering, the terms of Section 1.2(b)
shall apply to all participants in such offering. Registrations effected
pursuant to this Section 1.4 shall not be counted as demands for registration or
registrations effected pursuant to Sections 1.2 or 1.3, respectively.

                  1.5 EXPENSES OF REGISTRATION. All Registration Expenses
incurred in connection with any registration, qualification or compliance
pursuant to this Section 1 shall be borne by the Company except as follows:

                           (a) The Company shall not be required to pay for
expenses of any registration proceeding begun pursuant to Sections 1.2 or 1.4,
the request for which has been subsequently withdrawn by the Requesting Holders
or the Initiating Holders, in which case such expenses shall be borne by all of
the participating Holders unless, at the time of such withdrawal, the Holders
have learned of a material adverse change in the condition, business or
prospects of the Company from that known to the Requesting Holders or the
Initiating Holders at the time of their request.

                           (b) The Company shall not be required to pay
underwriters' fees, discounts or commissions, or stock transfer taxes relating
to Registrable Securities. The Company shall be required to pay the reasonable
fees and disbursements of one counsel for the Holders to be selected by Holders
of a majority of the Registrable Securities.

                                       8
<PAGE>

                  1.6 REGISTRATION PROCEDURES. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Rights
Agreement, the Company will keep each Holder participating therein advised in
writing as to the initiation of each registration, qualification and compliance
and as to the completion thereof. Whenever required under this Section 1 to
effect the registration of any Registrable Securities, the Company will as
expeditiously as reasonably possible:

                           (a) Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its best efforts
to cause such registration statement to become effective, and, upon the request
of the Holders of a majority of the Registrable Securities registered
thereunder, keep such registration statement effective until the distribution
contemplated by such registration statement is complete.

                           (b) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

                           (c) Furnish to the Holders such numbers of copies of
a prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.

                           (d) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such jurisdictions as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therewith
or as a condition thereto to qualify to do business or, except as required under
the Securities Act, to file a general consent to service of process in any such
states or jurisdictions.

                           (e) Notify each Holder of Registrable Securities
covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Securities Act of the happening of
any event as a result of which the prospectus included in such registration
statement, as then in effect, includes any untrue statement of material fact or
omits to state a material fact necessary to make the statements therein not
misleading in the light of the circumstances then existing, such obligation to
continue for one hundred twenty (120) days.

                           (f) Cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange or automated
quotation system on which similar securities issued by the Company are then
listed.

                           (g) Provide a transfer agent and registrar for all
Registrable Securities registered pursuant hereunder and a CUSIP number for all
such Registrable Securities, in each case not later than the effective date of
such registration.

                           (h) Use its best efforts to furnish, at the request
of any Holder requesting registration of Registrable Securities pursuant to this
Section 1.6, on the date that such

                                       9
<PAGE>

Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to Section 1.6, if such securities are being sold
through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such
securities becomes effective, (i) an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated such date, from
the independent certified public accounts of the Company, in form and substance
as is customarily given by independent certified public accounts to underwriters
in an underwritten public offering, addressed to the underwriters, if any, and
to the Holders requesting registration of Registrable Securities.

                  1.7 INDEMNIFICATION.

                           (a) The Company will indemnify and hold harmless each
Holder of Registrable Securities and each of its officers, directors and
partners, and each person controlling such Holder, with respect to which such
registration, qualification or compliance has been effected pursuant to this
Rights Agreement, and each underwriter, if any, and each person who controls any
underwriter of the Registrable Securities held by or issuable to such Holder,
against all claims, losses, expenses, damages and liabilities (or actions in
respect thereto) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any registration statement
(including any preliminary or final prospectus contained therein or any
amendments or supplements thereto) incident to any such registration,
qualification or compliance, or based on any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statement therein not misleading, or any violation or alleged violation by
the Company of the Securities Act, the Securities Exchange Act of 1934 (the
"Exchange Act") any state securities law or any rule or regulation promulgated
under the Securities Act, or the Exchange Act, and will reimburse each such
Holder, each of its officers, directors and partners, and each person
controlling such Holder, each such underwriter and each person who controls any
such underwriter, as incurred, for any reasonable legal and any other expenses
incurred by them in connection with investigating, defending or settling any
such claim, loss, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 1.7(a) shall not apply to amounts
paid in settlement of any such claim, loss, damage, liability, or action if such
settlement is effected without the consent of the Company (which consent shall
not be unreasonably withheld); and provided further, that the Company will not
be liable in any such case to the extent that any such claim, loss, damage or
liability arises out of or is based on any untrue statement or omission based
upon written information furnished to the Company by an instrument duly executed
by such Holder, controlling person or underwriter specifically for use therein.

                           (b) Each Holder will, if Registrable Securities held
by or issuable to such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify and hold
harmless the Company, each of its directors and officers who has signed the
registration statement, each underwriter, if any, of the Company's securities
covered by such a registration statement, each person who controls the Company
within the meaning of the Securities Act, the Company's legal counsel and each
other such selling Holder, each of its officers, directors and partners and each
person controlling such

                                       10
<PAGE>

Holder, against all claims, losses, expenses, damages and liabilities (or
actions in respect thereof) arising out of or based on any untrue statement of a
material fact contained in any such registration statement, (including any
preliminary or final prospectus contained therein or any amendments or
supplements thereto) or any omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse the Company, such Holders, such directors, officers,
partners, persons or underwriters for any reasonable legal or any other expenses
incurred in connection with investigating, defending or settling any such claim,
loss, damage, liability or action, in each case to the extent, but only to the
extent, that such untrue statement (or alleged untrue statement) or omission (or
alleged omission) is made in such registration statement in reliance upon and in
conformity with written information furnished to the Company by the Holder in an
instrument duly executed by such Holder specifically for use therein; provided,
however, that the indemnity agreement contained in this Section 1.7(b) shall not
apply to amounts paid in settlement of any such claim, loss, damage, liability
or action if such settlement is effected without the consent of the Holder
(which consent shall not be unreasonably withheld); and provided further, that
the total amount for which any Holder shall be liable under this Section 1.7(b)
shall not in any event exceed the net proceeds received by such Holder from the
sale of Registrable Securities held by such Holder in such registration.

                           (c) Each party entitled to indemnification under this
Section 1.7 (the "Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense; and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations hereunder, unless such failure resulted in
prejudice to the Indemnifying Party's ability to defend such action but the
omission so to deliver written notice to the indemnifying party will not relieve
it of any liability that it may have to any indemnified party otherwise than
under this Section 1.7; and provided further, that an Indemnified Party
(together with all other Indemnified Parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the Indemnifying Party, if
representation of such Indemnified Party by the counsel retained by the
Indemnifying Party would be inappropriate due to actual or potential differing
interests between such Indemnified Party and any other party represented by such
counsel in such proceeding. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation.

                           (d) If the indemnification provided for in this
Section 1.7 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable

                                       11
<PAGE>

by such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage or expense as well as any other relevant equitable
considerations; PROVIDED that in no event shall any contribution by a Holder
under this Subsection 1.7(d)exceed the net proceeds from the offering received
by such Holder. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

                           (e) The obligations of the Company and Holders under
this Section 1.7 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

                  1.8 INFORMATION BY HOLDER. Any Holder or Holders of
Registrable Securities included in any registration shall promptly furnish to
the Company such information regarding such Holder or Holders and the
distribution proposed by such Holder or Holders as the Company may request in
writing and as shall be required in connection with any registration,
qualification or compliance referred to herein.

                  1.9 RULE 144 REPORTING. With a view to making available to
Holders the benefits of certain rules and regulations of the SEC which may
permit the sale of the Registrable Securities to the public without
registration, the Company agrees at all times to:

                           (a) make and keep public information available, as
those terms are understood and defined in SEC Rule 144, after ninety (90) days
after the effective date of the first registration filed by the Company for an
offering of its securities to the general public;

                           (b) take such action, including the voluntary
registration of its Common Stock under Section 12 of the Exchange Act, as is
necessary to enable the Holders to utilize Form S-3 for the sale of their
Registrable Securities, such action to be taken as soon as practicable after the
end of the fiscal year in which the first registration statement filed by the
Company for the offering of its securities to the general public is declared
effective;

                           (c) file with the SEC in a timely manner all reports
and other documents required of the Company under the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements); and

                           (d) so long as a Holder owns any Registrable
Securities, to furnish to such Holder forthwith upon reasonable request a
written statement by the Company that it has complied with the reporting
requirements of said Rule 144 (at any time after ninety (90) days after the
effective date of the first registration statement filed by the Company for an
offering of its securities to the general public), the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements), or that it qualifies as a registrant whose securities may be
resold under Form S-3 (at any time after it so qualifies) a copy of the most

                                       12
<PAGE>

recent annual or quarterly report of the Company, and such other reports and
documents so filed by the Company as the Holder may reasonably request in
complying with any rule or regulation of the SEC allowing the Holder to sell any
such securities without registration.

                  1.10 TRANSFER OF REGISTRATION RIGHTS. Holders' rights to cause
the Company to register their securities and keep information available granted
to them by the Company under Section 1 may be assigned to a transferee or
assignee of at least the lesser of all or 300,000 shares (as adjusted for stock
splits, dividends, combinations or the like) of a Holder's Registrable
Securities or to an affiliated limited partnership or other affiliate of such
Holder, provided that the Company is given written notice by such Holder at the
time of or within a reasonable time after said transfer, stating the name and
address of said transferee or assignee and identifying the securities with
respect to which such registration rights are being assigned. The foregoing
limitation shall not apply, however, to (i) transfers by a Holder which is a
limited partnership to its partners or retired partners, an affiliated limited
partnership or other affiliate of such Holder; provided, however, that all such
transferees or assignees agree in writing to appoint a single representative as
their attorney-in-fact for the purpose of receiving any notices and exercising
their rights under this Section 1, (ii) transfers to another holder of
Registrable Securities who already possesses registration rights pursuant to the
terms of this Agreement, or (iii) transfers to a transferee or assignee
acquiring more than ten percent (10%) of the Company's outstanding capital
stock. The Company may prohibit the transfer of any Holders' rights under this
Section 1.10 to any proposed transferee or assignee who the Company reasonably
believes is a competitor of the Company.

                  1.11 "MARKET STAND-OFF" AGREEMENT. Each Holder hereby agrees
that, during the period of duration (not to exceed 180 days) specified by the
Company and an underwriter of common stock or other securities of the Company
following the effective date of a registration statement of the Company filed
under the Securities Act in connection with its initial public offering, it
shall not, to the extent requested by the Company and such underwriter, directly
or indirectly sell, offer to sell, contract to sell (including, without
limitation, any short sale), grant any option to purchase, pledge or otherwise
transfer or dispose of (other than to donees who agree to be similarly bound)
any Common Stock of the Company held by it at any time during such period except
Common Stock included in such registration; provided, however, that such
agreement shall not be required unless all officers and directors of the Company
enter into similar agreements. Anything in this Agreement to the contrary
notwithstanding, no Investor shall be prohibited under this Agreement from
freely acquiring or disposing of any Shares of the Common Stock of the Company
acquired by it on the public market (including, without limitation, shares of
the Company's Common Stock acquired in its initial public offering or any market
that may develop pursuant to Rule 144A under the Securities Act).

         In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of each
Holder (and the shares of securities of every other person subject to the
foregoing restriction) until the end of such period.

                  1.12 TERMINATION OF RIGHTS. All rights to cause the Company to
register securities under Sections 1.2, 1.3 or 1.4 shall terminate with respect
to such Holder upon the earlier to occur of (i) three years after the closing
date of the Company's initial public offering, or (ii) such time after the
Company has completed an initial public offering, it is subject to the

                                       13
<PAGE>

provisions of the Exchange Act, and such Holder, Holder's affiliates, partners
or former partners are able to distribute all Registrable Securities held or
issuable to such Holder, Holder's affiliates, partners or former partners
pursuant to Rule 144 during any ninety (90) day period.

         2. RIGHT OF FIRST OFFER TO PURCHASE EQUITY SECURITIES.

                  2.1 PURCHASE RIGHT. If at any time the Company should desire
to issue any Equity Securities (as hereinafter defined) in a transaction not
registered under the Securities Act in reliance upon a claimed exemption
thereunder, it shall give each Investor who holds at least 300,000 Series B
Shares, 300,000 Series B-1 Shares (or, in the case of Sony, 300,000 of Series B
Shares and Series B-1 Shares combined), any Series C Shares, any Series C-1
Shares or any Series C-2 Shares (as adjusted for stock splits, dividends,
combinations or the like) (a "Qualifying Investor") the first right to purchase
each Qualifying Investors' pro rata share (or any part thereof) of all of such
privately offered Equity Securities on the same terms as the Company is willing
to sell such Equity Securities to any other person (the "Purchase Right"). The
Qualifying Investors' pro rata share of the Equity Securities shall be equal to
that percentage of the outstanding Common Stock of the Company beneficially
owned by the Investors on the date hereof. For purposes of this Section 2, the
outstanding Common Stock of the Company shall include (i) outstanding shares of
Common Stock, and (ii) shares of Common Stock issued or issuable upon conversion
of any then outstanding Preferred Stock of the Company.

                  2.2 NOTICE OF INTENT TO SELL AND ISSUE. Prior to any sale or
issuance by the Company of any Equity Securities, the Company shall notify each
Qualifying Investor in writing of its intention to sell and issue such
securities, setting forth the number of shares to be offered and the price and
terms under which it proposes to make such sale. Within fifteen (15) days after
receipt of such notice, each Qualifying Investor shall notify the Company
whether the Qualifying Investor desires to exercise the option to purchase the
Qualifying Investor's pro rata share (or any part thereof) of the Equity
Securities so offered. In no event shall the Qualifying Investor be obligated to
purchase any Equity Securities pursuant to this Section 2, nor does the
Qualifying Investor make any representation or warranty that it plans to do so.
The foregoing notwithstanding, each Qualifying Investor purchasing its full pro
rata share of the Equity Securities so offered shall be further entitled to
elect to purchase within ten (10) days after receipt of notice the additional
Equity Securities available as a result of other Investors not purchasing their
full pro rata shares on a pro rata basis based on the number of shares of
Outstanding Common Stock held by such fully exercising Qualifying Investor as a
percentage of the Outstanding Common Stock held by all fully exercising
Qualifying Investors.

                  2.3 INVESTOR FAILURE TO PURCHASE. After termination of the
twenty-five (25) day period specified in Section 2.2 above, the Company may,
during a period of sixty (60) days following the end of such twenty-five (25)
day period, sell and issue such Equity Securities as to which the Qualifying
Investors do not indicate a desire to purchase to another person at a price not
less than, and upon terms and conditions no less favorable to the Company than
those set forth in the notice to the Investors. In the event the Company has not
sold the Equity Securities, or has not entered into an agreement to sell the
Equity Securities, within said sixty (60) day period, the Company shall not
thereafter issue or sell any Equity Securities without first offering such
securities to the Qualifying Investors in the manner provided above.

                                       14
<PAGE>

                  2.4 INVESTOR PURCHASE. If a Qualifying Investor gives the
Company notice that the Qualifying Investor desires to purchase any of the
Equity Securities offered by the Company, payment for the Equity Securities
shall be by check or wire transfer against delivery of the Equity Securities at
the executive offices of the Company within twenty (20) days after giving the
Company such notice, or, if later, the closing date for the sale of such Equity
Securities. The Company shall take all such action as may be required by any
regulatory authority in connection with the exercise by the Qualifying Investor
of the Purchase Right.

                  2.5 EXCLUDED SECURITIES. The Purchase Right contained in this
Section 2 shall not apply to the issuance by the Company of Equity Securities
(i) to employees, officers, directors or consultants of the Company pursuant to
stock purchase or stock option plans or agreements when unanimously approved by
the Company's Board of Directors, (ii) as part of an acquisition by the Company
of assets or shares of another company or entity whether through a merger,
exchange, reorganization or the like, (iii) issued pursuant to the Antidilution
Agreements dated as of June 7, 1999, September 28, 1999 and December 14, 1999
(the "Antidilution Agreements") by and between the Company and certain
Investors, (iv) issued upon conversion of the Preferred Stock of the Company,
(v) issued in connection with any stock split, stock dividend, recapitalization
or similar event, (vi) issued in connection with any commercial debt or lease
financing transaction approved by the Company's Board of Directors, (vii) issued
in the IPO, (viii) issued to Overly Publishing ("Overly") pursuant to the terms
of the Joint Marketing Agreement between the Company and Overly dated as of June
1999, (ix) issued to vendors or customers or to other persons in similar
commercial situations with the Company if such issuance is approved by the
Company's Board of Directors, or (x) issued in connection with corporate
partnering transactions on terms approved by the Company's Board of Directors.

                  2.6 TERMINATION. The Purchase Right shall terminate as to all
Qualifying Investors upon the closing of the IPO.

                  2.7 EQUITY SECURITIES. The term "Equity Securities" shall mean
(i) Common Stock and rights, options or warrants to purchase Common Stock, (ii)
any security other than Common Stock having voting rights in the election of the
Board of Directors, not contingent upon a failure to pay dividends, (iii) any
security convertible into or exchangeable for any of the foregoing, and (iv) any
agreement or commitment to issue any of the foregoing.

         3. RIGHT OF FIRST REFUSAL.

                  3.1 NOTICE.

                           (a) In the event Michael C. Pousti, Jr. ( "Pousti")
desires to accept one or more bona fide offers (a "Purchase Offer") from any
person to purchase any of the 10,130,975 shares of Common Stock owned by Pousti
or his affiliates, or any shares acquired by Pousti or his affiliates in the
future (collectively, the "Founders Shares"), other than as specifically
provided in Section 4.6 below, Pousti, must notify Investors holding a minimum
of 300,000 (as adjusted for stock splits, dividends, combinations or the like)
Series B Shares, Series B-1 Shares, or, in the case of Sony, Series B Shares and
Series B-1 Shares together, Series C Shares, Series C-1 Shares or Series C-2
Shares and the Company in writing (the "Notice"). The Notice shall state the
terms and conditions of the Purchase Offer, including the number of Founders
Shares

                                       15
<PAGE>

proposed to be sold or transferred, the nature of such sale or transfer, the
consideration to be paid, and the name and address of each prospective purchaser
or transferee.

                           (b) In the event the proposed transfer is partially
or completely in exchange for assets other than cash, then such assets shall be
deemed to have a cash value in the amount determined unanimously by the
Company's Board of Directors (with Pousti abstaining) in its sole good faith
opinion, in which case such cash value ascertained by the Board, when added to
any cash to be exchanged and then divided by the number of Founders Shares to be
transferred, shall be deemed the price per share set forth in the Notice. In the
event of a gift, property settlement or other transfer in which the proposed
purchaser or transferee is not paying the full price for the Founders Shares,
which transfer is not otherwise exempted pursuant to Section 4.6 hereof, the
price shall be deemed to be the fair market value of the Founders Shares as
determined unanimously and in good faith by the Board of Directors (with Pousti
abstaining).

                  3.2 EXERCISE OF RIGHT OF FIRST REFUSAL.

                           (a) The Company shall have an exclusive, irrevocable
option (the "Company Option"), at any time within thirty (30) days of receipt of
the Notice, to purchase some or all of the Founders Shares to which the Notice
refers at the price per share specified in the Notice (or as otherwise
calculated pursuant to Section 3.1(b)). The Company shall exercise the Company's
Option by written notice signed by an officer of the Company and delivered or
mailed to Pousti (the "Company's Settlement Notice"), which notice shall specify
the time, place and date for settlement of such purchase.

                           (b) In the event (i) the Company elects not to
exercise the Company's Option, (ii) the Company elects to exercise the Company's
Option for only a portion of the Founders Shares to which the Notice refers, or
(iii) the Company's Option expires upon the failure of the Company to timely
deliver or mail the Company's Settlement Notice, Investors holding a minimum of
300,000 (as adjusted for stock splits, dividends, combinations or like) of
Series B Shares, Series B-1 Shares, or, in the case of Sony, Series B Shares and
Series B-1 Shares together, Series C Shares, Series C-1 Shares, Series C-2
Shares or their assignee(s) shall have an exclusive, irrevocable option (the
"Investors' Option"), at any time within twenty (20) days after the earlier of:
(A) the Investor's receipt of such election notice of the Company pursuant to
subsection 3.2(b) (i) or (ii) or (B) the expiration of such thirty (30) day
period, to elect to purchase some or all of the Founders Shares to which the
Notice refers, or the balance of the Founders Shares to which the Notice refers
for which the Company has not exercised the Company's Option, at the price per
share specified in the Notice (or as otherwise calculated pursuant to Section
3.1 (b)). Each such Investor shall have the right to purchase its pro rata share
of the Founders' Shares so offered, based on the number of Series B Shares,
Series B-1 Shares, Series C Shares, Series C-1 Shares or Series C-2 Shares held
by such Investor as a percentage of the number of Series B Shares, Series B-1
Shares, Series C Shares, Series C-1 Shares or Series C-2 Shares held by all such
Investors holding at least 300,000 Series B Shares, Series B-1 Shares, Series C
Shares, Series C-1 Shares or Series C-2 Shares. The Investors shall exercise the
Investors' Option by written notice delivered or mailed to Pousti (the
"Investors' Settlement Notice") within such 20-day period, which notice shall
specify the time, place and date for settlement of such purchase. If any
Investors do not exercise their Investor's Option, the Shares that would
otherwise be allocated to such non-exercising Investors shall be allocated to
each

                                       16
<PAGE>

exercising Investor on a pro rata basis (based upon the number of Series B
Shares, Series B-1 Shares, Series C Shares, Series C-1 Shares or Series C-2
Shares held by such Investor relative to the aggregate number of Series B
Shares, Series B-1 Shares, Series C Shares, Series C-1 Shares or Series C-2
Shares held by all such exercising Investors), provided that the Investor's
Option must be exercised, if at all, on or before three days after the
expiration of the twenty day period referenced above.

                  3.3 SETTLEMENT.

                           (a) Within ten (10) days of receipt of the Company
Settlement Notice, Pousti must deliver to the Company all certificates for the
Equity Securities being acquired by the Company which are not already in the
Company's custody, together with proper assignments in blank of the Founders
Shares with signatures properly guaranteed and with such other documents as may
be required by the Company to provide reasonable assurance that each necessary
endorsement is genuine and effective, and the Company must thereupon deliver to
Pousti full cash payment for the Founders Shares being acquired, provided that
if the terms of payment set forth in the Notice were other than cash against
delivery, the Company shall pay for said shares on the same terms and conditions
set forth in such Notice.

                           (b) Within ten (10) days of receipt of the Investors'
Settlement Notice, Pousti and the Company, to the extent certificates for said
Founders Shares may be held by each, respectively, must deliver to the Investors
all certificates for the Founders Shares being acquired by the Investors which
are not already in the Investors' custody, together with proper assignments in
blank of the Founders Shares with signatures properly guaranteed and with such
other documents as may be required by the Investors to provide reasonable
assurance that each necessary endorsement is genuine and effective, and the
Investors must thereupon deliver to Pousti full cash payment for the Founders
Shares being acquired, provided that if the terms of payment set forth in the
Notice were other than cash against delivery, the Investors shall pay for said
shares on the same terms and conditions set forth in such Notice.

                  3.4 REVIVAL OF RIGHT OF FIRST REFUSAL. If all of the Founders
Shares which the Company and/or the Investors are entitled to obtain pursuant to
Section 3.2 hereof is not elected to be obtained as provided in Section 3.2
hereof and the Co-Sale Right in Section 4 is not exercised, Pousti may, during
the sixty (60) day period following the expiration of the last period provided
in Section 4.2 hereof, offer the remaining unsubscribed portion of such Founders
Shares to any person or persons at a price not less than, and upon terms no more
favorable to the transferee than those specified in the Notice. If Pousti does
not enter into an agreement for the sale of the Founders Shares within such
sixty (60) day period, or if such agreement is not consummated within sixty (60)
days after the execution thereof, the right provided hereunder shall be deemed
to be revived and such Founders Shares shall not be offered unless first
re-offered in accordance with Section 3.2 hereof.

         4. CO-SALE RIGHT.

                  4.1 NOTICE OF SALES. Should Pousti propose to accept one or
more bona fide offers (collectively, a "Purchase Offer") from any persons to
purchase Founders Shares owned by him (other than as set forth in Section 4.6
hereof), then subject to the rights of the Investors

                                       17
<PAGE>

and the Company as set forth in Section 3 above, and upon the expiration or
waiver of such right of first refusal, Pousti shall promptly deliver a Notice to
the Company and each Investor holding a minimum of 300,000 (as adjusted for
stock splits, dividends, combinations or the like) Series B Shares, Series B-1
Shares or, in the case of Sony, Series B Shares and Series B-1 Shares together,
Series C Shares, Series C-1 Shares or Series C-2 Shares.

                  4.2 CO-SALE RIGHT. Each Investor described in Section 4.1
shall have the right (the "Co-Sale Right"), exercisable upon written notice to
the Company within thirty (30) days after the expiration of the Investors'
Option pursuant to Section 3.2, to participate in Pousti's sale, pursuant to the
specified terms and conditions of such Purchase Offer. Each Investor described
in Section 4.1 may sell all or any part of that number of Series B Shares,
Series B-1 Shares, Series C Shares, Series C-1 Shares or Series C-2 Shares (or
Common Stock issued on conversion thereof) equal to the product obtained by
multiplying (i) the aggregate number of Founders Shares covered by the Purchase
Offer by (ii) a fraction, the numerator of which is the number of Series B
Shares, Series B-1 Shares, Series C Shares, Series C-1 Shares or Series C-2
Shares (assuming conversion thereof) at the time owned by such Investor and the
denominator of which is the sum of (A) the total number of Series B Shares,
Series B-1 Shares, Series C Shares, Series C-1 Shares or Series C-2 Shares
(assuming conversion thereof) at the time owned by all such Investors
participating in such sale plus (B) the total number of Founders Shares at the
time owned by such Founder, including shares transferred by such Founder to
Permitted Transferees (as defined below) in accordance with this Agreement. To
the extent an Investor exercises such Co-Sale Right in accordance with the terms
and conditions set forth below, the number of Equity Securities which Pousti may
sell pursuant to such Purchase Offer shall be correspondingly reduced.

                  4.3 DELIVERY OF CERTIFICATES. Each Investor exercising the
Co-Sale Right may effect its participation in Pousti's sale by delivering to
Pousti for transfer to the prospective purchaser one or more certificates,
properly endorsed for transfer, which represent that Investor's Equity
Securities which such Investor elects to sell.

                  4.4 TRANSFER. The stock certificate or certificates which the
participating Investor delivers to Pousti pursuant to Section 4.3 shall be
delivered by Pousti to the prospective purchaser in consummation of the sale
pursuant to the terms and conditions specified in the Notice, and Pousti shall
promptly thereafter remit to such Investor that portion of the sale proceeds to
which such Investor is entitled by reason of its participation in such sale. To
the extent that any prospective purchaser or purchasers prohibit such assignment
or otherwise refuse to purchase such Investor's Series B Shares, Series B-1
Shares, Series C Shares, Series C-1 Shares or Series C-2 Shares (or Common Stock
issued on conversion thereof) from an Investor exercising its Co-Sale Right
hereunder, Pousti shall not sell to such prospective purchaser or purchasers any
Founders Shares unless and until, simultaneously with such sale, Pousti shall
purchase such Investor's Series B Shares, Series B-1 Shares, Series C Shares,
Series C-1 Shares or Series C-2 Shares (or Common Stock issued on conversion
thereof) from such Investor for the same consideration and on the same terms and
conditions as the proposed transfer described in the Notice (which terms and
conditions shall be no less favorable than those governing the sale to the
purchaser by Pousti).

                                       18
<PAGE>

                  4.5 NO ADVERSE EFFECT. The exercise or non-exercise of the
Co-Sale Rights of the qualified Investors hereunder to participate in one or
more sales of Founders Shares made by a Founder shall not adversely affect their
rights to participate in subsequent sales of Founders Shares by a Founder.

                  4.6 PERMITTED TRANSACTIONS. The provisions of Sections 3 and 4
of this Agreement shall not pertain or apply to:

                           (a) Any bona fide gift; or

                           (b) Any transfer to Pousti's ancestors, descendants
or spouse or to a trust for his or their benefit (and any distributions from
such trust); PROVIDED, in each case, that the transferee or donee (each a
"Permitted Transferee") shall execute a written agreement to be bound by and
comply with all provisions of this Agreement applicable to Pousti.

                  4.7 TERMINATION OF RIGHTS. The provisions of Sections 3 and 4
of this Agreement shall terminate upon the closing of an IPO or a merger or
acquisition of the Company by a public company.

                  4.8 ASSIGNMENT OF RIGHTS. The rights of the Investors set
forth in Section 2, Section 3 and/or Section 4 may be assigned (but only with
all related obligations) only to a transferee or assignee of at least the lesser
of all or 300,000 (as adjusted for stock splits, dividends, combinations or the
like) Series B Shares, Series B-1 Shares, Series C Shares, Series C-1 Shares or
Series C-2 Shares (or Common Stock issued on conversion thereof), provided that
(a) the Company is, within a reasonable time after such transfer, furnished with
written notice of the name and address of such transferee or assignee and the
securities with respect to which such rights are being assigned; (b) such
transferee agrees in writing to be bound by the provisions of this Agreement;
and (c) such transferee is not a competitor of the Company, as determined in
good faith by the Company's Board of Directors. Notwithstanding the foregoing,
any Investor may transfer its rights set forth in Section 2, Section 3 and/or
Section 4 without regard to the minimum number of shares described in the first
sentence of this Section 4.8 if the transferee is a person or entity
controlling, controlled by or under common control with such Investor.

                  4.9 PROHIBITED TRANSFERS. Any attempt by Pousti to transfer
Founders Shares in violation of Section 3 or Section 4 of this Agreement shall
be void and the Company agrees it will not effect such a transfer nor will it
treat any alleged transferee as the holder of such shares.

                  4.10 LEGENDED CERTIFICATES. Each certificate representing
shares of the Common Stock or Preferred Stock of the Company now or hereafter
owned by the Founder or issued to any Permitted Transferee pursuant to Section
4.6 shall bear the following legend:

                  THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
                  REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
                  CONDITIONS OF A CERTAIN INVESTORS' RIGHTS AGREEMENT BY AND
                  BETWEEN THE STOCKHOLDER, THE CORPORATION AND CERTAIN HOLDERS
                  OF PREFERRED STOCK OF THE CORPORATION. COPIES OF SUCH
                  AGREEMENT

                  CORPORATION.

         5. BOARD VISITATION. Until the closing of an IPO or a merger or
acquisition of the Company by a public company, a designee of Sony shall be
permitted to attend and observe all meetings of the Company's Board of
Directors, but shall have none of the powers, rights or duties of a member of
the Board of Directors.

         6. AMENDMENT, RESTATEMENT AND WAIVER OF RIGHTS OF PARTIES TO PRIOR
RIGHTS AGREEMENT; ADDITION OF PARTIES.

                  6.1 AMENDMENT, RESTATEMENT OF PRIOR RIGHTS AGREEMENT; APPROVAL
OF GRANT OF RIGHTS TO INVESTORS. The Company warrants that the Parties to this

         8. GENERAL.

                  8.1 WAIVERS AND AMENDMENTS. With the written consent of the
Company and the holders of at least a majority of the Registrable Securities,
any term of this Agreement may be amended or waived (either generally or in a
particular instance, either retroactively or prospectively, and either for a
specified period of time or indefinitely); provided, however, that no such
modification, amendment or waiver shall reduce the aforesaid percentage of
Registrable Securities needed to amend or waive a provision of this Agreement
without the consent of all of the Holders of the Registrable Securities or
disproportionately affect the holders of the Series B Shares, the Series B-1
Shares, the Series C Shares, the Series C-1 Shares or the Series C-2 Shares
without the approval of holders of a majority of the outstanding shares of such
series; provided, further, that no such amendment may alter the terms of Section
1.11 adversely to a party hereto holding over 2,000,000 Series C Shares without
such party's consent. Upon the effectuation of each such waiver, consent,
agreement of amendment or modification, the Company shall promptly give written
notice thereof to the record holders of the Registrable Securities who have not
previously consented thereto in writing. Any amendment or waiver effected in
accordance with this Section 8.1 shall be binding upon the Company, the holders
of Registrable Securities and any holder of Founders' Shares, and each of their
respective successors and assigns; and any

                                       21
<PAGE>

such amendment or waiver effected in accordance with this Section 8.1 shall be
binding upon the Company, the holders of Registrable Securities and any holder
of Founders' Shares (and each of their respective successors and assigns)
notwithstanding whether NBC or any of the Versity Investors have entered into
the Agreement, however, the Company shall not issue any such Registrable
Securities to NBC or any Versity Investor unless and until NBC or such Versity
Investor executes and delivers a counterpart to this Agreement. Any provision of
Section 2.1 may be amended or waived in a manner adverse to Sony or Convergence
only with the prior written consent of the Company and Convergence or Sony, as
applicable.

                  8.2 GOVERNING LAW. This Agreement shall be governed in all
respects by the laws of the State of California as such laws are applied to
agreements between California residents entered into and to be performed
entirely within California.

                  8.3 SUCCESSORS AND ASSIGNS. Except as otherwise expressly
provided herein, the provisions hereof shall inure to the benefit of, and be
binding upon, the successors, assigns, heirs, executors and administrators of
the parties hereto.

                  8.4 ENTIRE AGREEMENT. Except as set forth below, this
Agreement and the other documents delivered pursuant hereto constitute the full
and entire understanding and agreement between the parties with regard to the
subjects hereof and thereof.

                  8.5 NOTICES, ETC. All notices and other communications
required or permitted hereunder shall be in writing and shall be delivered
effective (i) upon personal delivery, (ii) one business day after delivery to a
reputable overnight courier service, (iii) upon the earlier of receipt or three
(3) business days after deposit in U.S. mail, if mailed by first class mail,
postage prepaid, certified or registered mail, return receipt requested,
addressed (a) if to the Investors, at the addresses as set forth on EXHIBIT A
hereto, or at such other addresses as any Investors shall have furnished to the
Company in writing; or (b) if to the Company, at 1010 East Second Avenue, East
Tower, Suite 600, San Diego, CA 92101, Attn.: Raffaele G. Fazio, Esq., Vice
President, Legal, or at such other address as the Company shall have furnished
to the Investors in writing.

                  8.6 SEVERABILITY. If any provision of this Agreement, or the
application thereof, is for any reason and to any extent determined by a court
of competent jurisdiction to be invalid or unenforceable, the remainder of this
Agreement and the application of such provision to other persons or
circumstances will be interpreted so as best to reasonably effect the intent of
the parties hereto. The parties agree to use their best efforts to replace such
void or unenforceable provision of this Agreement with a valid and enforceable
provision which will achieve, to the extent greatest possible, the economic,
business and other purposes of the void or unenforceable provision.

                  8.7 TITLES AND SUBTITLES. The titles of the sections and
Sections of this Agreement are for convenience of reference only and are not to
be considered in construing this Agreement.

                  8.8 COUNTERPARTS. This Agreement may be executed in any number
of counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

                  8.9 QUALIFIED SMALL BUSINESS STOCK STATUS. In the event that
the Company proposes to take an action or engage in a transaction that would
reasonably be expected to result in the Registrable Securities no longer being
"qualified small business stock" within the meaning of Section 1202(c) of the
Internal Revenue Code of 1986, as amended (the "Code"), the Company shall notify
the Investors and consult in good faith to devise a mutually agreeable and
reasonable alternative course of action or transaction structure that would
preserve such status. In addition, the Company shall submit to the Investors and
to the Internal Revenue Service any reports that may be required under Section
1022(d)(1)(C) of the Code and any related Treasury Regulations. In addition,
within ten (10) days after any Investor has delivered to the Company a written
request therefore, the Company shall deliver to such Investor a written
statement informing the Investor whether, in the Company's good faith judgment,
after a reasonable investigation, such Investor's interest in the Company
constitutes "qualified small business stock" as defined in Section 1202(c) of
the Code. The Company's obligation to furnish a written statement pursuant to
this Section 8.9 shall continue notwithstanding the fact that a class of the
Company's stock may be traded on an established securities market.

                  8.10 AFFILIATED FUNDS. For purposes of counting the number of
shares held by the parties to this Agreement, shares held by partners, persons
or entities directly, or indirectly through one or more intermediaries,
controlling, controlled by or under common control with a party hereto shall by
aggregated together. For so long as funds advised by Seligman own in total the
number of shares necessary to exercise the various rights set forth herein,
Seligman shall be entitled to exercise such rights on behalf of such funds.
