     2.   REQUIRED REGISTRATION.

          (a)  On or after October 30, 2003, (i) the holders of Original
Restricted Stock (excluding the Founders) constituting at least a majority in
interest of the total shares of Series A Preferred Stock then outstanding and/or
(ii) the holders of Original Restricted Stock (excluding the Series A
Purchasers) constituting at least seventy-five percent (75%) of the Common Stock
then outstanding may request the Company to register under the Securities Act
all or any portion of the shares of Original Restricted Stock held by such
requesting holder or holders for sale in the manner specified in such notice
(subject to the limitations set forth in subsection 2(g) hereof), provided that
the aggregate price to the public of such offering would exceed $5,000,000.

          (b)  On or after April 16, 2002, the holders of Series B/C/D/E/F
Restricted Stock constituting at least 30% in interest of the total shares of
Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock,
Series E Preferred Stock and Series F Preferred Stock then outstanding may
request the Company to register under the Securities Act all or any portion of
the shares of Series B/C/D/E/F Restricted Stock held by such requesting holder
or holders for sale in the manner specified in such notice (subject to the
limitations set forth in subsection 2(g) hereof), PROVIDED that the aggregate
price to the public of such offering would exceed $5,000,000.

          (c)  The only securities which the Company shall be required to
register pursuant to this Section 2 shall be shares of Common Stock; provided,
however, that, in any underwritten public offering contemplated by this Section
2 or Sections 3 and 4, the holders of Preferred Shares shall be entitled to sell
such Preferred Shares to the underwriters for conversion and sale of the shares
of Common Stock issued upon conversion thereof. Notwithstanding anything to the
contrary contained herein, the Company shall not be required to effect a
registration of shares of its Common Stock pursuant to this Section 2 within 180
days after the effective date of a registration statement filed by the Company
covering a firm commitment underwritten public offering in which the holders of
Restricted Stock shall have been entitled to join pursuant to Sections 3 or 4.

          (d)  Following receipt of any notice under subsection 2(a), the
Company shall immediately notify all holders of Original Restricted Stock
(including the Founders) from whom notice has not been received and such holders
shall then be entitled within 30 days thereafter to request the Company to
include in the requested registration all or any portion of their shares of
Original Restricted Stock. The Company shall use its best efforts to register
under the Securities Act, for public sale in accordance with the method of
disposition described in subsection 2(a), the number of shares of Original
Restricted Stock specified in such notice (and in all notices received by the
Company from other holders within 30 days after the


                                       5
<PAGE>   6


giving of such notice by the Company). The Company shall be obligated to
register Original Restricted Stock pursuant to subsection 2(a) on two occasions
only as follows: (i) one at the request of Series A Purchasers holding Original
Restricted Stock who have so requested pursuant to clause (i) of subsection 2(a)
and (ii) one at the request of holders of Common Stock who have so requested
pursuant to clause (ii) of subsection 2(a); PROVIDED, HOWEVER, that such
obligation shall be deemed satisfied only when a registration statement,
covering all of the offered shares of Original Restricted Stock specified in
notices received as aforesaid for sale in accordance with the method of
disposition specified by the requesting holders, shall have become effective or
if such registration statement has been withdrawn prior to the consummation of
the offering at the request of the Series A Purchasers (other than as a result
of a material adverse change in the business or financial condition of the
Company) and, if such method of disposition is a firm commitment underwritten
public offering, all such shares shall have been sold pursuant thereto.

          (e)  Following receipt of any notice under subsection 2(b), the
Company shall immediately notify all holders of Series B/C/D/E/F Restricted
Stock from whom notice has not been received and such holders shall then be
entitled within 30 days thereafter to request the Company to include in the
requested registration all or any portion of their shares of Series B/C/D/E/F
Restricted Stock. The Company shall use its best efforts to register under the
Securities Act, for public sale in accordance with the method of disposition
described in subsection 2(b), the number of shares of Series B/C/D/E/F
Restricted Stock specified in such notice (and in all notices received by the
Company from other holders within 30 days after the giving of such notice by the
Company). The Company shall be obligated to register Series B/C/D/E/F Restricted
Stock pursuant to subsection 2(b) on three occasions only; provided, however,
that such obligation shall be deemed satisfied only when a registration
statement, covering all of the offered shares of Series B/C/D/E/F Restricted
Stock specified in notices received as aforesaid for sale in accordance with the
method of disposition specified by the requesting holders, shall have become
effective or if such registration statement has been withdrawn prior to the
consummation of the offering at the request of the Series B Purchasers, the
Series D Purchaser, the Series E Purchaser or the Series F Purchaser (other than
as a result of a material adverse change in the business or financial condition
of the Company) and, if such method of disposition is a firm commitment
underwritten public offering, all such shares shall have been sold pursuant
thereto, or, if such method of disposition includes the resale of the shares
from time to time at prevailing market prices, such registration statement has
remained effective and available for resale for at least 120 days.

          (f)  The Company (or at the option of the Company, the holders of
Common Stock) shall be entitled to include in any registration statement
referred to in this Section 2, for sale in accordance with the method of
disposition specified by the requesting holders, shares of Common Stock to be
sold by the Company for its own account or the account of such other holders,
except as and to the extent that, in the opinion of the managing underwriter (if
such method of disposition shall be an underwritten public offering), such
inclusion would adversely affect the marketing of the Restricted Stock to be
sold subject to the limitations set forth in subsection 2(g) hereof). Except for
registration statements on Form S-4, S-8 or any successor thereto, the Company
will not file with the Commission any other registration statement with respect
to its Common Stock, whether for its own account or that of other stockholders,
from the


                                       6
<PAGE>   7


date of receipt of a notice from requesting holders pursuant to this Section 2
until the completion of the period of distribution of the registration
contemplated thereby.

          (g)  If, in the opinion of the managing underwriter, the inclusion of
all of the Restricted Stock requested to be registered under this Section would
adversely affect the marketing of such shares, then, (i) in the case of a
registration requested pursuant to clause (i) of subsection 2(a), shares to be
sold by the Company or other holders of Common Stock (including the Founders)
shall first be excluded, and then if necessary, shares of Original Restricted
Stock to be sold by the Series A Purchasers shall be excluded in such manner
that the shares to be sold shall be allocated among the Series A Purchasers
selling Original Restricted Stock pro rata based on their ownership of Original
Restricted Stock, (ii) in the case of a registration requested pursuant to
clause (ii) of subsection 2(a), shares to be sold by the Company or any other
holders of Common Stock (excluding the Founders and including any shares of
Original Restricted Stock held by the Series A Purchasers) shall first be
excluded, and then if necessary, shares of Original Restricted Stock to be sold
by the Founders shall be excluded in such manner that the shares to be sold
shall be allocated among the Founders selling Original Restricted Stock pro rata
based on their ownership of Original Restricted Stock, and (iii) in the case of
a registration requested pursuant to subsection 2(b), shares to be sold by the
Company or other holders of Common Stock shall first be excluded, and then if
necessary, shares of Series B/C/D/E/F Restricted Stock to be sold by the Series
B Purchasers, the Series D Purchaser, the Series E Purchaser and the Series F
Purchaser shall be excluded in such a manner that the shares to be sold shall be
allocated among the Series B Purchasers, the Series D Purchaser, the Series E
Purchaser and the Series F Purchaser selling Series B/C/D/E/F Restricted Stock
pro rata based on their ownership of Series B/C/D/E/F Restricted Stock;
provided, however, that in any registration in which both the Series A
Purchasers and Founders shall have requested registration pursuant to both
clauses (i) and (ii) of subsection 2(a), then shares to be sold by the Company
or other holders of Common Stock (including the Founders) shall first be
excluded, and then if necessary, shares of Original Restricted Stock to be sold
by the Series A Purchasers shall be excluded in such manner that the shares to
be sold shall be allocated among the Series A Purchasers selling Original
Restricted Stock pro rata based on their ownership of Original Restricted Stock.

     3.        INCIDENTAL REGISTRATION. If, following the Company's first
registered public offering of its Common Stock, the Company at any time (other
than pursuant to Section 2 or Section 4) proposes to register any of its
securities under the Securities Act for sale to the public, whether for its own
account only or for its own account and for the account of other security
holders (except with respect to registration statements on Forms S-4, S-8 or
another form not available for registering the Restricted Stock for sale to the
public), each such time it will give written notice to all Purchasers holding
outstanding Restricted Stock of its intention so to do. Upon the written request
of any such holder received by the Company within 30 days after the giving of
any such notice by the Company to register at least 900,000 shares
(appropriately adjusted for any of the events specified in Section 8 herein) of
its Restricted Stock, the Company will use its best efforts to cause the
Restricted Stock as to which registration shall have been so requested to be
included in the securities to be covered by the registration statement proposed
to be filed by the Company, all to the extent requisite to permit the sale or
other disposition by the


                                       7
<PAGE>   8


holder (in accordance with such written request) of such Restricted Stock so
registered. In the event that any registration pursuant to this Section 3 shall
be, in whole or in part, an underwritten public offering of Common Stock, the
number of shares of Restricted Stock to be included in such an underwriting may
be reduced (pro rata among the requesting holders based upon the number of
shares of Restricted Stock held by such requesting holders) if and to the extent
that the managing underwriter shall be of the opinion that such inclusion would
adversely affect the marketing of the securities to be sold by the Company
therein, but in no event shall the amount of securities of the requesting
holders be reduced below thirty percent (30%) of the total amount to be included
in such offering; provided, however, that such number of shares of Restricted
Stock shall not be reduced if any shares are to be included in such underwriting
for the account of any person (including the Founders) other than the Company or
requesting Purchasers holding Restricted Stock. Notwithstanding the foregoing
provisions, the Company may withdraw any registration statement referred to in
this Section 3 without thereby incurring any liability to the holders of
Restricted Stock.

     4.        REGISTRATION ON FORM S-3.

          (a)  If at any time (i) a holder or holders of Restricted Stock then
outstanding request that the Company file a registration statement on Form S-3
or any successor thereto for a public offering of all or any portion of the
shares of Restricted Stock held by such requesting holder or holders, the
reasonably anticipated aggregate price to the public of which would exceed
$1,000,000, and (ii) the Company is a registrant entitled to use Form S-3 or any
successor thereto to register such shares, then the Company shall use its best
efforts to register under the Securities Act on Form S-3 or any successor
thereto, for public sale in accordance with the method of disposition specified
in such notice, the number of shares of Restricted Stock specified in such
notice. Whenever the Company is required by this Section 4 to use its best
efforts to effect the registration of Restricted Stock, each of the procedures
and requirements of Section 2 (including but not limited to the requirement that
the Company notify all holders of Restricted Stock from whom notice has not been
received and provide them with the opportunity to participate in the offering)
shall apply to such registration, PROVIDED, HOWEVER, that no more than two (2)
registrations on Form S-3 may be requested and obtained under this Section 4
within any twelve (12) month period preceding the date of such request.

          (b)  Notwithstanding anything to the contrary set forth in this
Agreement, the Company's obligation under this Agreement to register Restricted
Stock under the Securities Act on registration statements ("REGISTRATION
STATEMENTS") may, upon the reasonable determination of the Board of Directors
made only once during any 12-month period, be suspended in the event and during
such period as unforeseen circumstances (including without limitation (i) an
underwritten primary offering by the Company (which includes no secondary
offering) if the Company is advised in writing by its underwriters that the
registration of the Restricted Stock would have a material adverse effect on the
Company's offering, or (ii) pending negotiations relating to, or consummation
of, a transaction or the occurrence of an event which would require additional
disclosure of material information by the Company in Registration Statements or
such other filings, as to which the Company has a bona fide business purpose for
preserving confidentiality or which renders the Company unable to comply with
the Commission's


                                       8
<PAGE>   9


requirements) exist (such unforeseen circumstances being hereinafter referred to
as a "SUSPENSION EVENT") which would make it impractical or inadvisable for the
Company to file the Registration Statements or such other filings or to cause
such to become effective. Such suspension shall continue only for so long as
such event is continuing but in no event for a period longer than ninety (90)
days. The Company shall notify the Purchasers of the existence and nature of any
Suspension Event.

     5.   REGISTRATION PROCEDURES. If and whenever the Company is required by
the provisions of Sections 2, 3 or 4 to use its best efforts to effect the
registration of any shares of Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:

          (a)  prepare and file with the Commission a registration statement
(which, in the case of an underwritten public offering pursuant to Section 2,
shall be on Form S-1 or other form of general applicability satisfactory to the
managing underwriter selected as therein provided) with respect to such
securities and use its best efforts to cause such registration statement to
become and remain effective for the period of the distribution contemplated
thereby (determined as hereinafter provided);

          (b)  prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above and comply with the provisions of
the Securities Act with respect to the disposition of all Restricted Stock
covered by such registration statement in accordance with the sellers' intended
method of disposition set forth in such registration statement for such period;

          (c)  furnish to each seller of Restricted Stock and to each
underwriter such number of copies of the registration statement and each such
amendment and supplement thereto (in each case including all exhibits) and the
prospectus included therein (including each preliminary prospectus) as such
persons reasonably may request in order to facilitate the public sale or other
disposition of the Restricted Stock covered by such registration statement;

          (d)  use its best efforts to register or qualify the Restricted Stock
covered by such registration statement under the securities or "BLUE SKY" laws
of such jurisdictions as the sellers of Restricted Stock or, in the case of an
underwritten public offering, the managing underwriter reasonably shall request;
PROVIDED, HOWEVER, that the Company shall not for any such purpose be required
to qualify generally to transact business as a foreign corporation in any
jurisdiction where it is not so qualified or to consent to general service of
process in any such jurisdiction;

          (e)  use its best efforts to list the Restricted Stock covered by such
registration statement with any securities exchange on which the Common Stock of
the Company is then listed;


                                       9
<PAGE>   10


          (f)  immediately notify each seller of Restricted Stock and each
underwriter under 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 of which the Company has knowledge as a result of which
the prospectus contained in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing, and promptly prepare
and furnish to such seller a reasonable number of copies of a prospectus
supplemented or amended so that, as thereafter delivered to the purchasers of
such Restricted Stock, such prospectus shall not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein not misleading in light of the
circumstances then existing;

          (g)  if the offering is underwritten and at the request of any seller
of Restricted Stock, use its best efforts to furnish to such seller on the date
that Restricted Stock is delivered to the underwriters for sale pursuant to such
registration: (i) a copy of an opinion dated such date of counsel representing
the Company for the purposes of such registration, addressed to the underwriters
and to such seller, to such effect as reasonably may be requested by counsel for
the underwriters, and (ii) a letter dated such date from the independent public
accountants retained by the Company, addressed to the underwriters and to such
seller, stating that they are independent public accountants within the meaning
of the Securities Act and that, in the opinion of such accountants, the
financial statements of the Company included in the registration statement or
the prospectus, or any amendment or supplement thereof, comply as to form in all
material respects with the applicable accounting requirements of the Securities
Act, and such letter shall additionally cover such other financial matters
(including information as to the period ending no more than five business days
prior to the date of such letter) with respect to such registration as such
underwriters reasonably may request;

          (h)  make available for inspection by each seller of Restricted Stock,
any underwriter participating in any distribution pursuant to such registration
statement, and any attorney, accountant or other agent retained by such seller
or underwriter, reasonable access to all financial and other records, pertinent
corporate documents and properties of the Company, as such parties may
reasonably request, and cause the Company's officers, directors and employees to
supply all information reasonably requested by any such seller, underwriter,
attorney, accountant or agent in connection with such registration statement;

          (i)  cooperate with the selling holders of Restricted Stock and the
managing underwriters, if any, to facilitate the timely preparation and delivery
of certificates representing Restricted Stock to be sold, such certificates to
be in such denominations and registered in such names as such holders or the
managing underwriters may request at least two business days prior to any sale
of Restricted Stock; and

          (j)  permit any holder of Restricted Stock which holder, in the sole
and exclusive judgment, exercised in good faith, of such holder, might be deemed
to be a controlling person of the Company, to participate in good faith in the
preparation of such registration or


                                       10
<PAGE>   11


comparable statement and to require the insertion therein of material, furnished
to the Company in writing, which in the reasonable judgment of such holder and
its counsel should be included.

          For purposes of Section 5(a) and 5(b) and of Section 2(f), the period
of distribution of Restricted Stock in a firm commitment underwritten public
offering shall be deemed to extend until each underwriter has completed the
distribution of all securities purchased by it, and the period of distribution
of Restricted Stock in any other registration shall be deemed to extend until
the earlier of the sale of all Restricted Stock covered thereby and 180 days
after the effective date thereof.

          In connection with each registration hereunder, the sellers of
Restricted Stock will furnish to the Company in writing such information
requested by the Company with respect to themselves and the proposed
distribution by them as reasonably shall be necessary in order to assure
compliance with federal and applicable state securities laws and to make the
registration statement correct, accurate and complete in all respects with
respect to such sellers; provided, however, that this requirement shall not be
deemed to limit any disclosure obligation arising out of any seller's
relationship to the Company if one of such seller's agents or affiliates is an
officer, director or control person of the Company. In addition, the sellers
shall, if requested by the Company, execute such other agreements, which are
reasonably satisfactory to them and which shall contain such provisions as may
be customary and reasonable in order to accomplish the registration of the
Restricted Stock.

          In connection with each registration pursuant to Sections 2, 3 or 4
covering an underwritten public offering, the Company and each seller agree to
enter into a written agreement with the managing underwriter selected in the
manner herein provided in such form and containing such provisions as are
customary in the securities business for such an arrangement between such
underwriter and companies of the Company's size and investment stature.

     6.   EXPENSES. All expenses incurred by the Company in complying with
Sections 2, 3 and 4, including, without limitation, all registration and filing
fees, printing expenses, fees and disbursements of counsel and independent
public accountants for the Company, fees and expenses (including counsel fees)
incurred in connection with complying with state securities or "BLUE SKY" laws,
fees and expenses of one counsel for the selling holders of Restricted Stock in
connection with the registration of Restricted Stock (which counsel shall be
selected (i) by the Series A Purchasers selling Original Restricted Stock if
such registration is made pursuant to clause (i) of subsection 2(a), (ii) by the
Founders selling Original Restricted Stock if such registration is made pursuant
to clause (ii) of subsection 2(a), and (iii) by the holders of at least 30% in
interest of shares of Series B/C/D/E/F Restricted Stock if such registration is
made pursuant to subsection 2(b); PROVIDED, HOWEVER, if both the Series A
Purchasers and the Founders register shares of Original Restricted Stock
pursuant to subsection 2(a), such counsel shall be selected by the Series A
Purchasers, subject to approval by the Founders (which approval shall not be
unreasonably withheld)), fees of the National Association of Securities Dealers,
Inc., transfer taxes, fees of transfer agents and registrars, costs of any
insurance which might be obtained, but excluding any Selling Expenses, are
called "REGISTRATION EXPENSES". All underwriting discounts and selling


                                       11
<PAGE>   12


commissions applicable to the sale of Restricted Stock and the fees and expenses
of more than one counsel for the selling holders of Restricted Stock in
connection with the registration of Restricted Stock are called "SELLING
EXPENSES".

          The Company will pay all Registration Expenses in connection with each
registration statement under Sections 2, 3 or 4. All Selling Expenses in
connection with each registration statement under Sections 2, 3 or 4 shall be
borne by the participating sellers in proportion to the number of shares sold by
each, or by such participating sellers other than the Company (except to the
extent the Company shall be a seller) as they may agree.

     7.   INDEMNIFICATION.

          (a)  In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Sections 2, 3 or 4, the Company will
indemnify and hold harmless each holder of Restricted Stock, its officers and
directors, each underwriter of such Restricted Stock thereunder and each other
person, if any, who controls such seller or underwriter within the meaning of
the Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which such holder, officer, director, underwriter or controlling
person may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
Restricted Stock was registered under the Securities Act pursuant to Sections 2,
3 or 4, any preliminary prospectus or final prospectus contained therein, or any
amendment or supplement thereof, (ii) any blue sky application or other document
executed by the Company specifically for that purpose or based upon written
information furnished by the Company filed in any state or other jurisdiction in
order to qualify any or all of the Restricted Stock under the securities laws
thereof (any such application, document or information herein called a "BLUE SKY
APPLICATION"), (iii) the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, (iv) any violation by the Company or its agents of any
rule or regulation promulgated under the Securities Act applicable to the
Company or its agents and relating to action or inaction required of the Company
in connection with such registration, or (v) any failure to register or qualify
the Restricted Stock in any state where the Company or its agents has
affirmatively undertaken or agreed in writing that the Company (the undertaking
of any underwriter chosen by the Company being attributed to the Company) will
undertake such registration or qualification on the seller's behalf (provided
that in such instance the Company shall not be so liable if it has undertaken
its best efforts to so register or qualify the Restricted Stock) and will
reimburse each such holder, and such officer and director, each such underwriter
and each such controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; PROVIDED, HOWEVER, that the Company will not
be liable in any such case if and to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission so made in conformity
with information furnished by any such seller, any such underwriter or any such
controlling person in writing specifically for use in such registration
statement or prospectus.


                                       12
<PAGE>   13


          (b)  In the event of a registration of any of the Restricted Stock
under the Securities Act pursuant to Sections 2, 3 or 4, each seller of such
Restricted Stock thereunder, severally and not jointly, will indemnify and hold
harmless the Company, each person, if any, who controls the Company within the
meaning of the Securities Act, each officer of the Company who signs the
registration statement, each director of the Company, each other holder of
Restricted Stock, each underwriter and each person who controls any underwriter
within the meaning of the Securities Act, against all losses, claims, damages or
liabilities, joint or several, to which the Company or such officer, director,
other seller, underwriter or, controlling person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
the registration statement under which such Restricted Stock was registered
under the Securities Act pursuant to Sections 2, 3 or 4, any preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof, or any Blue Sky Application or arise out of or are based upon the
omission or alleged 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 and each such officer, director, other seller,
underwriter and controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action, PROVIDED, HOWEVER, that such seller will be
liable hereunder in any such case if and only to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in conformity with information pertaining to such seller, as such, furnished
in writing to the Company by such seller specifically for use in such
registration statement or prospectus, and PROVIDED, FURTHER, HOWEVER, that the
liability of each seller hereunder shall be limited to the proportion of any
such loss, claim, damage, liability or expense which is equal to the proportion
that the public offering price of the shares sold by such seller under such
registration statement bears to the total public offering price of all
securities sold thereunder, but not in any event to exceed the proceeds received
by such seller from the sale of Restricted Stock covered by such registration
statement.

          (c)  Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 7 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 7 if and to the extent the indemnifying party is prejudiced by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under this Section 7 for any legal expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of


                                       13
<PAGE>   14


investigation and of liaison with counsel so selected; PROVIDED, HOWEVER, that,
if the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that the interests of the indemnified party reasonably may be deemed to conflict
with the interests of the indemnifying party, the indemnified party shall have
the right to select a separate counsel and to assume such legal defenses and
otherwise to participate in the defense of such action, with the expenses and
fees of such separate counsel and other expenses related to such participation
to be reimbursed by the indemnifying party as incurred.

          (d)  The indemnities provided in this Section 7 shall survive the
transfer of any Restricted Stock by such holder.

     8.   CHANGES IN COMMON STOCK OR PREFERRED STOCK. If, and as often as, there
is any change in the Common Stock or the Preferred Shares by way of a stock
split, stock dividend, combination or reclassification, or through a merger,
consolidation, reorganization or recapitalization, or by any other means,
appropriate adjustment shall be made in the provisions hereof so that the rights
and privileges granted hereby shall continue with respect to the Common Stock or
the Preferred Shares as so changed.

     9.   RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Stock to the public without registration, at all times
after 90 days after any registration statement covering a public offering of
securities of the Company under the Securities Act shall have become effective,
the Company agrees to:

          (a)  make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

          (b)  use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and

          (c)  furnish to each holder of Restricted Stock forthwith upon request
a written statement by the Company as to its compliance with the reporting
requirements of such Rule 144 and of the Securities Act and the Exchange Act, a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents so filed by the Company as such holder may
reasonably request in availing itself of any rule or regulation of the
Commission allowing such holder to sell any Restricted Stock without
registration.

     10.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents
and warrants to you as follows:

          (a)  The execution, delivery and performance of this Agreement by the
Company have been duly authorized by all requisite corporate action and will not

<PAGE>   15


of the Company or any provision of any indenture, agreement or other instrument
to which it or any of its properties or assets is bound, conflict with, result
in a breach of or constitute (with due notice or lapse of time or both) a
default under any such indenture, agreement or other instrument or result in the
creation or imposition of any lien, charge or encumbrance of any nature
whatsoever upon any of the properties or assets of the Company.

          (b)  This Agreement has been duly executed and delivered by the
Company and constitutes the legal, valid and binding obligation of the Company,
enforceable in accordance with its terms, except to the extent the
indemnification provisions herein may be deemed not enforceable.

     11.  MISCELLANEOUS.

          (a)  TRANSFERS; ASSIGNS. All covenants and agreements contained in
this Agreement by or on behalf of any of the parties hereto shall bind and inure
to the benefit of the respective successors and assigns of the parties hereto
(including without limitation transferees of any Preferred Shares or Restricted
Stock), whether so expressed or not; PROVIDED, HOWEVER, that registration rights
conferred herein on the holders of Preferred Shares, Common Stock or Restricted
Stock shall only inure to the benefit of a transferee of Preferred Shares,
Common Stock or Restricted Stock if (i) there is transferred to such transferee
at least 600,000 shares of such stock (appropriately adjusted for any of the
events specified in Section 8 hereof) to the direct or indirect transferor of
such transferee or (ii) such transferee is a Qualified Transferee (as such term
is defined in that certain Fourth Amended and Restated Stockholders' Agreement
by and among the Company, the Purchasers and the Founders (the "STOCKHOLDERS'
AGREEMENT")) and (iii), that such transferee executes a writing agreeing to be
bound by the provisions of this Agreement and the Stockholders' Agreement (to
the extent the same remains in effect).

          (b)  NOTICES. All notices, requests, consents and other communications
hereunder shall be in writing and shall be mailed by certified or registered
mail, return receipt requested, postage prepaid, or telexed, in the case of
non-U.S. residents, addressed as follows:

party and its counsel set forth in the Series A Purchase Agreement, Series B
Purchase Agreement, the Series D Purchase Agreement, the Series E Purchase
Agreement, the Series F Purchase Agreement or in the Stockholders' Agreement
with a copy to the Company's counsel as indicated in the Series A Purchase

<PAGE>   16


          (c)  GOVERNING LAW. This Agreement shall be construed and enforced in
accordance with and governed by the General Corporation Law of the State of

shall be governed by and construed in accordance with the internal laws of the
Commonwealth of Massachusetts.

Shares, (ii) at least 50% of the Conversion Shares, and (iii) at least 60% of
the outstanding shares of Series B/C/D Restricted Stock; provided, however, that

Sections 2 and 3 of this Agreement, shall not be effective without the written
consent of the holders of at least 50% of the outstanding shares of Series
B/C/D/E/F Restricted Stock. Notwithstanding the foregoing, no amendment,
modification or waiver approved in accordance herewith shall be effective if and
to the extent such amendment, modification or waiver directly or indirectly
grants to the holders of any type of Restricted Stock any rights more favorable
than any rights granted hereunder to the holders of any other type of Restricted
Stock or otherwise treats the holders of any type of Restricted Stock
differently than the holders of any other type of Restricted Stock. Any
amendment, modification or waiver to this Section 11(d) shall require the
written consent of the holders of (i) at least 50% of the Founders' Registrable
Shares, (ii) at least 50% of the Conversion Shares, (iii) at least 60% of the
outstanding shares of Series B/C/D Restricted Stock, and (iv) at least 50% of

for the initial underwritten public offering of securities of the Company, each
holder of Restricted Stock who is a party to this Agreement shall agree not to
sell publicly any shares of Restricted Stock or any other shares of Common Stock
(other than shares of Restricted Stock or other shares of Common Stock being
registered in such offering), without the consent of such underwriters, for a
period of not more than 180 days following the effective date of the
registration statement relating to such offering; PROVIDED, HOWEVER, that all
(i) persons entitled to registration rights with respect to shares of Common
Stock who are not parties to this Agreement, (ii) executive officers, (iii)
directors and (iv) employees who hold, or have been awarded options to purchase,
an aggregate of up to 720,000 shares of Common Stock of the Company, shall also
have agreed not to sell publicly their shares of Common Stock under the
circumstances and pursuant to the terms set forth in this Section 11(g).

          (h)  OTHER REGISTRATIONS. The Company shall not grant to any third
party any registration rights comparable to or more favorable than any of those

be illegal, invalid or unenforceable, such illegality, invalidity or
unenforceability shall attach only to such provision and shall not in any manner
affect or render illegal, invalid or unenforceable any other provision of this
Agreement, and this Agreement shall be carried out as if any such illegal,
invalid or unenforceable provision were not contained herein.

Series A Purchasers, the Series B Purchasers, the Series D Purchaser and the
Series E Purchaser (including the holders of at least (i) 50% of the Founders'
Registrable Shares, (ii) 50% of the Conversion Shares, and (iii) 60% of the
outstanding shares of Series B/C/D Restricted Stock (as such terms are defined
