other parties to this Agreement at such time complete information for notices
under this Agreement.

hereby agrees that such Group A Stockholder shall not Transfer any of its Equity
Securities at any time prior to the fifth anniversary of the First Closing,

                                                                  --------
further, however, that notwithstanding any other provision in this Section

preceding proviso) (i) during the First Transfer Period, a number of Equity

prevent a Transfer by a Group A Stockholder during his lifetime or on death by
gift, will or intestacy to his immediate family or to a trust, partnership or
other entity, the beneficiaries, partners or equityholders of which are
exclusively such Group A Stockholder and/or members of his immediate family,
provided that it is expressly understood that any such Transferee shall be, and
shall agree in a writing reasonably satisfactory to the Investor Stockholder to
be, bound by the provisions of this Agreement. Each Group A Stockholder shall as
promptly as practicable provide the Investor Stockholder with written notice of
any Transfer made in accordance with this Section 3.2(b).

          (c)  Transfers by the Group B Stockholders.  Each Group B Stockholder
               -------------------------------------
hereby agrees that it shall not Transfer any of its Equity Securities at any
time prior to the third anniversary of the First Closing, unless the Investor
Stockholder shall agree to such Transfer in writing; provided, however, that in
                                                     --------  -------
the event of an Investor Stockholder Transfer, subject to Section 3.2(d), each
Group B Stockholder shall be permitted to Transfer (to the extent not
Transferred pursuant to the immediately succeeding proviso) a number of Equity

one month after notice has been provided to such Group B Stockholder of the
applicable Investor Stockholder Transfer, which notice shall be provided within
20 days of the consummation of the Investor Stockholder Transfer; provided,
                                                                  --------
further, however, that notwithstanding any other provision in this Section

3.2(c) and subject to Section 3.2(d), each Group B Stockholder shall be
permitted to Transfer (to the extent not Transferred pursuant to the immediately
preceding proviso) (i) during the First Transfer Period, a number of Equity

Securities equal to 15% of its Period Ownership for the Second Transfer Period
and (iii) during the Third Transfer Period, a number of Equity Securities equal
to 15% of its Period Ownership for the Third Transfer Period; provided, further,
                                                              --------  -------
however, that nothing in this Section 3.2(c) shall prevent a Transfer by a Group
-------
B Stockholder during his lifetime or on death by gift, will or intestacy to his
immediate family or to a trust, partnership or other entity, the beneficiaries,
partners or equityholders of which are exclusively such Group B Stockholder
and/or members of his immediate family, provided that it is expressly understood
that any such Transferee shall be, and shall agree in a writing reasonably
satisfactory to the Investor Stockholder to be, bound by the provisions of this
Agreement. Each Group B Stockholder shall as promptly as practicable provide the
Investor Stockholder with written notice of any Transfer made in accordance with
this Section 3.2(c).

          (d)  Pledges.  During such time as the Group A Stockholders and the
               -------
Group B Stockholders shall be bound by the provisions of Sections 3.2(b) and
(c), respectively, each such stockholder shall be permitted to pledge (a
"Pledge") a number of Equity Securities equal to such stockholder's Permitted
 ------
Pledge Amount on such date to one or more Permitted Pledgees. Upon any Pledge
made by any Group A Stockholder or Group B Stockholder in accordance with this
Section 3.2(d), the aggregate number of Equity Securities which may be
Transferred by such stockholder during the applicable Transfer Period in
accordance with the first and second provisos of each of Sections 3.2(b) and
(c), as applicable, shall be reduced by a number of Equity Securities equal to
one-half of the number of Equity Securities which have been so Pledged. Any
foreclosure or sale of Pledged Equity Securities shall be deemed a Transfer with
respect to all such Pledged Equity Securities.

          (e)  Carry Forwards.  If any Group A Stockholder or Group B
               --------------
Stockholder does not Transfer all of the Equity Securities it is permitted to
Transfer during any Transfer Period in accordance with the second proviso of
Section 3.2(b) or (c) (after taking into account Transfers pursuant to the first
proviso of each such Section), as applicable, such stockholder shall be
permitted to carry forward to subsequent Transfer Periods that percentage of
unsold Equity Securities that such stockholder would have otherwise been
entitled to Transfer during the applicable Transfer Period in accordance with
such proviso. If, due to a foreclosure or sale of Pledged Equity Securities, any
Group A Stockholder or Group B Stockholder Transfers any Equity Securities in
excess of the Permitted Transfer Amount for such Transfer Period, such excess
shall reduce the Permitted Transfer Amounts for such stockholder for the
subsequent Transfer Periods.


                       ARTICLE IV    REGISTRATION RIGHTS
                                     -------------------
<PAGE>

                                                                              20

          SECTION IV.1  Incidental Registrations.  (a) If the Company at any
                        ------------------------
time after the date hereof proposes to register Equity Securities under the
Securities Act (other than a registration on Form S-4 or S-8, or any successor
or other forms promulgated for similar purposes), whether or not for sale for
its own account, in a manner which would permit registration of Registrable
Securities for sale to the public under the Securities Act, it will, at each
such time, give prompt written notice to all Holders of its intention to do so
and of such Holders' rights under this Article IV. Upon the written request of
any such Holder made within 15 days after the receipt of any such notice (which
request shall specify the Registrable Securities intended to be disposed of by
such Holder), the Company will use its commercially reasonable best efforts to
effect the registration under the Securities Act of all Registrable Securities
which the Company has been so requested to register by the Holders thereof;
provided, that (a) if, at any time after giving written notice of its intention
--------
to register any securities, the Company shall determine for any reason not to
proceed with the proposed registration of the securities to be sold by it, the
Company may, at its election, give written notice of such determination to each
Holder and, thereupon, shall be relieved of its obligation to register any
Registrable Securities in connection with such registration (but not from its
obligation to pay the Registration Expenses in connection therewith), and (b) if
such registration involves an underwritten offering, all Holders requesting to
be included in the Company's registration must sell their Registrable Securities
to the underwriters selected by the Company on the same terms and conditions as
apply to the Company, with such differences, including any with respect to
indemnification and liability insurance, as may be customary or appropriate in
combined primary and secondary offerings. If a registration requested pursuant
to this Section involves an underwritten public offering, any Holder requesting
to be included in such registration may elect, in writing prior to the effective
date of the registration statement filed in connection with such registration,
not to register all or any part of such securities in connection with such
registration. Nothing in this Section shall operate to limit the right of any
Holder to request the registration of Common Stock issuable upon conversion,
exchange or exercise of securities held by such Holder notwithstanding the fact
that at the time of request such Holder does not hold the Common Stock
underlying such securities. The registrations provided for in this Section 4.1
are in addition to, and not in lieu of, registrations made upon the request of
the Investor Stockholder in accordance with Section 4.2.

          (b)  Expenses.  The Company will pay all Registration Expenses in
               --------
connection with each registration of Registrable Securities requested pursuant
to this Section 4.1.

          (c)  Priority in Incidental Registrations.  If a registration pursuant
               ------------------------------------
to this Section 4.1 involves an underwritten offering and the managing
underwriter advises the Company in writing that, in its opinion, the number of
Registrable Securities requested to be included in such registration would be
likely to have an adverse effect on the price, timing or distribution of the
securities to be offered in such offering as contemplated by the Company (other
than the Registrable Securities), then the Company shall include in such
registration (a) first, 100% of the securities the Company proposes to sell, (b)
                 -----
second, any Other Securities requested to be registered by any Other Holders
------
exercising a demand registration right, and (c) third, to the extent of the
                                                -----
amount of Registrable Securities and Other Securities requested to be included
in such registration which, in the opinion of such managing underwriter, can be
sold without having the adverse effect referred to above, the amount of
Registrable Securities and Other Securities which the Holders and the Other
Holders have requested to be included in such registration, such
<PAGE>

                                                                              21


amount to be allocated pro rata among all requesting Holders and the Other
Holders on the basis of the relative amount of Registrable Securities and Other
Securities then held by each such Holder and Other Holder (provided, that any
                                                           --------
such amount thereby allocated to any such Holder or Other Holder that exceeds
such Holder's or Other Holder's request shall be reallocated among the remaining
requesting Holders and Other Holders in like manner).

          SECTION IV.2  Registration on Request.  (a)  At any time after the
                        -----------------------
date hereof, upon the written request of the Investor Stockholder (and any other
Holder; provided that no Transferee of any Investor Stockholder or its
        --------
Affiliates or of any Transferee shall be permitted to request a registration
pursuant to this Section 4.2 unless the right to make such a request was
transferred to such Transferee pursuant to Section 3.1(b)(ii)) (the "Demand
                                                                     ------
Party") requesting that the Company effect the registration under the Securities
-----
Act of all or part of such Demand Party's Registrable Securities and specifying
the amount and intended method of disposition thereof, the Company will promptly
give written notice of such requested registration to all other Holders, and
thereupon will, as expeditiously as possible, use its commercially reasonable
best efforts to effect the registration under the Securities Act of:

          (i)  the Registrable Securities which the Company has been so
     requested to register by the Demand Party; and

          (ii) all other Registrable Securities of the same class(es) or series
     as are to be registered at the request of a Demand Party and which the
     Company has been requested to register by any other Holder thereof by
     written request given to the Company within 15 days after the giving of
     such written notice by the Company (which request shall specify the amount
     and intended method of disposition of such Registrable Securities), all to
     the extent necessary to permit the disposition (in accordance with the
     intended method thereof as aforesaid) of the Registrable Securities so to
     be registered; provided, that in no event shall the Company be required to
                    --------
     effect more than three registrations pursuant to this Section 4.2 (which
     number shall be increased to four in the event a Qualified Option Closing
     occurs); and provided, further, that, the Company shall not be obligated to
                  --------  -------
     file a registration statement relating to any registration request under
     this Section 4.2 (other than a registration statement on Form S-3 or any
     successor or similar short-form registration statement) within a period of
     90 days after the effective date of any other registration statement
     relating to any registration request under this Section 4.2 or to any
     registration effected under Section 4.1, in either case which was not
     effected on Form S-3 (or any successor or similar short-form registration
     statement). Nothing in this Section 4.2 shall operate to limit the right of
     any Holder to request the registration of Common Stock issuable upon
     conversion of the Preferred Stock or the conversion, exchange or exercise
     of any other securities held by such Holder notwithstanding the fact that
     at the time of request such Holder does not hold the Common Stock
     underlying such securities.

          (b)  Registration Statement Form.  The Company shall select the
               ---------------------------
registration statement form for any registration pursuant to this Section 4.2;

provided, that if any registration requested pursuant to this Section 4.2 which
--------
is proposed by the Company to be effected by the filing of a registration
statement on Form S-3 (or any successor or similar short-form registration
<PAGE>

                                                                              22

statement) shall be in connection with an underwritten public offering, and if
the managing underwriter shall advise the Company in writing that, in its
opinion, the use of another form of registration statement is of material
importance to the success of such proposed offering, then such registration
shall be effected on such other form.

          (c)  Expenses.  The Company will pay all Registration Expenses in
               --------
connection with registrations of each class or series of Registrable Securities
pursuant to this Section 4.2.

          (d)  Effective Registration Statement.  A registration requested
               --------------------------------
pursuant to this Section 4.2 will not be deemed to have been effected unless it
has become effective and all of the Registrable Securities registered thereunder
have been sold.

          (e)  Selection of Underwriters.  If a requested registration pursuant
               -------------------------
to this Section 4.2 involves an underwritten offering, the investment banker(s),
underwriter(s) and manager(s) for such registration shall be selected by the
Holders of a majority of the Registrable Securities which the Company has been
requested to register; provided, however, that such investment banker(s),
                       --------  -------
underwriter(s) and manager(s) shall be reasonably satisfactory to the Company.

          (f)  Priority in Requested Registrations.  If a requested registration
               -----------------------------------
pursuant to this Section 4.2 involves an underwritten offering and the managing
underwriter advises the Company in writing that, in its opinion, the number of
securities to be included in such registration (including securities of the
Company which are not Registrable Securities) would be likely to have an adverse
effect on the price, timing or distribution of the securities to be offered in
such offering as contemplated by the Holders (an "Adverse Effect"), then the
                                                  --------------
Company shall include in such registration (a) first, 100% of the Registrable
                                               -----
Securities requested to be included in such registration by the Demand Party and
all other Holders of Registrable Securities pursuant to this Section 4.2 (to the
extent that the managing underwriter believes that all such Registrable
Securities can be sold in such offering without having an Adverse Effect;

provided, that if they cannot and the Demand Party does not exercise its right

set forth in the second succeeding sentence of this clause (f), such lesser
number of Registrable Securities as specified by the Demand Party) and (b)

second, to the extent the managing underwriter believes additional securities

can be sold in the offering without having an Adverse Effect, the amount of
Other Securities requested to be included by Other Holders in such registration,
allocated pro rata among all requesting Other Holders on the basis of the
relative amount of all Other Securities then held by each such Other Holder
(provided, that any such amount thereby allocated to any such Other Holder that
---------
exceeds such Other Holder's request shall be reallocated among the remaining
requesting Other Holders in like manner).  In the event that the number of
Registrable Securities and Other Securities to be included in such registration
is less than the number which, in the opinion of the managing underwriter, can
be sold without having an Adverse Effect, the Company may include in such
registration the securities the Company proposes to sell up to the number of
securities that, in the opinion of such managing underwriter, can be sold
without having an Adverse Effect.  If the managing underwriter of any
underwritten offering shall advise the Holders participating in a registration
pursuant to this Section 4.2 that the Registrable Securities covered by the
registration statement cannot be sold in such offering within a price range
acceptable to the Demand Party, then the Demand Party shall have the right to
notify the

Company that it has determined that the registration statement be abandoned or
withdrawn, in which event the Company shall abandon or withdraw such
registration statement.

          (g) Postponements in Requested Registrations.  Notwithstanding Section
              ----------------------------------------
4.2(f), (i) if the Board determines, in its good faith judgment, that the
registration and offering otherwise required by this Section 4.2 would have an
adverse effect on a then contemplated public offering of the Company's Equity
Securities, the Company may postpone the filing (but not the preparation) of a
registration statement required by this Section 4.2, during the period starting
with the 30/th/ day immediately preceding the date of the anticipated filing of,
and ending on a date 60 days following the effective date of, the registration
statement relating to such other public offering and (ii) if the Company shall
at any time furnish to the Holders a certificate signed by its chairman of the
board, chief executive officer, president or any other of its authorized
officers stating that the Company has pending or in process a material
transaction, the disclosure of which would, in the good faith judgment of the
Board, after consultation with its outside securities counsel, materially and
adversely affect the Company, the Company may postpone the filing (but not the
preparation) of a registration statement required by this Section 4.2 for up to
90 days; provided, that, the Company shall at all times in good faith use its
         --------
commercially reasonable best efforts to cause any registration statement
required by this Section 4.2 to be filed as soon as possible and; provided,
                                                                  --------
further, that, the Company shall not be permitted to postpone registration
-------
pursuant to this Section 4.2(g) more than once in any 360-day period. The
Company shall promptly give the Holders requesting registration thereof pursuant
to this Section 4.2 written notice of any postponement made in accordance with
the preceding sentence. If the Company gives the Holders such a notice, the
Holders shall have the right, within 15 days after receipt thereof, to withdraw
their request in which case, such request will not be counted for purposes of
this Section 4.2.

          SECTION IV.3  Registration Procedures.  If and whenever the Company is
                        -----------------------
required to use its commercially reasonable best efforts to effect or cause the
registration of any Registrable Securities under the Securities Act as provided
in this Agreement, the Company will promptly:

          (a)  prepare and, in any event within 45 days after the end of the
period within which a request for registration may be given to the Company, file
with the SEC a registration statement with respect to such Registrable
Securities and use its commercially reasonable best efforts to cause such
registration statement to become effective within 90 days of the initial filing;

          (b)  prepare and file with the SEC 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 a period not
in excess of 180 days and to comply with the provisions of the Securities Act
and the Exchange Act with respect to the disposition of all securities covered
by such registration statement during such period in accordance with the
intended methods of disposition by the seller or sellers thereof set forth in
such registration statement; provided, that before filing a registration
                             --------
statement or prospectus, or any amendments or supplements thereto in accordance
with Sections 4.3(a) or (b), the Company will furnish to
<PAGE>

                                                                              24

counsel selected pursuant to Section 4.8 hereof copies of all documents proposed
to be filed, which documents will be subject to the review of such counsel;

          (c)  furnish to each seller of such Registrable Securities such number
of copies of such registration statement and of each amendment and supplement
thereto (in each case including all exhibits filed therewith, including any
documents incorporated by reference), such number of copies of the prospectus
included in such registration statement (including each preliminary prospectus
and summary prospectus), in conformity with the requirements of the Securities
Act, and such other documents as such seller may reasonably request in order to
facilitate the disposition of the Registrable Securities by such seller;

          (d)  use its commercially reasonable best efforts to register or
qualify such Registrable Securities covered by such registration in such
jurisdictions as each seller shall reasonably request, and do any and all other
acts and things which may be reasonably necessary or advisable to enable such
seller to consummate the disposition in such jurisdictions of the Registrable
Securities owned by such seller, except that the Company shall not for any such
purpose be required to qualify generally to do business as a foreign corporation
in any jurisdiction where, but for the requirements of this subsection (d), it
would not be obligated to be so qualified, to subject itself to taxation in any
such jurisdiction or to consent to general service of process in any such
jurisdiction;

          (e)  use its commercially reasonable best efforts to cause such
Registrable Securities covered by such registration statement to be registered
with or approved by such other governmental authorities as may be necessary to
enable the seller or sellers thereof to consummate the disposition of such
Registrable Securities;

          (f)  notify each seller of any such 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 Company's becoming
aware that the prospectus included 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 the light of the circumstances then existing, and at
the request of any such seller, prepare and furnish to such seller a reasonable
number of copies of an amended or supplemental prospectus as may be necessary so
that, as thereafter delivered to the purchasers of such Registrable Securities,
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 the light of the circumstances then
existing;

          (g)  otherwise use its best efforts to comply with all applicable
rules and regulations of the SEC, and make available to its security holders, as
soon as reasonably practicable (but not more than 18 months) after the effective
date of the registration statement, an earnings statement which shall satisfy
the provisions of Section 11(a) of the Securities Act;

          (h)  (i)  if such Registrable Securities are Common Stock (including
Common Stock issuable upon conversion, exchange or exercise of another
security), use its commercially reasonable best efforts to list such Registrable
Securities on any securities exchange on which the
<PAGE>

                                                                              25

Common Stock is then listed if such Registrable Securities are not already so
listed and if such listing is then permitted under the rules of such exchange;
and (ii) use its best efforts to provide a transfer agent and registrar for such
Registrable Securities covered by such registration statement not later than the
effective date of such registration statement;

          (i)  enter into such customary agreements (including an underwriting
agreement in customary form), which may include indemnification provisions in
favor of underwriters and other Persons in addition to, or in substitution for
the provisions of Section 4.6 hereof, and take such other actions as sellers of
a majority of shares of such Registrable Securities or the underwriters, if any,
reasonably requested in order to expedite or facilitate the disposition of such
Registrable Securities;

          (j)  obtain a "cold comfort" letter or letters from the Company's
independent public accounts in customary form and covering matters of the type
customarily covered by "cold comfort" letters as the seller or sellers of a
majority of shares of such Registrable Securities shall reasonably request;

          (k)  make available for inspection by any seller of such Registrable
Securities covered by such registration statement, by any underwriter
participating in any disposition to be effected pursuant to such registration
statement and by any attorney, accountant or other agent retained by any such
seller or any such underwriter, all pertinent financial and other records,
pertinent corporate documents and properties of the Company, and cause all of
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;

          (l)  notify counsel (selected pursuant to Section 4.8 hereof) for the
Holders of Registrable Securities included in such registration statement and
the managing underwriter or agent, immediately, and confirm the notice in
writing (i) when the registration statement, or any post-effective amendment to
the registration statement, shall have become effective, or any supplement to
the prospectus or any amendment to the prospectus shall have been filed, (ii) of
the receipt of any comments from the SEC, (iii) of any request of the SEC to
amend the registration statement or amend or supplement the prospectus or for
additional information, and (iv) of the issuance by the SEC of any stop order
suspending the effectiveness of the registration statement or of any order
preventing or suspending the use of any preliminary prospectus, or of the
suspension of the qualification of the registration statement for offering or
sale in any jurisdiction, or of the institution or threatening of any
proceedings for any of such purposes;

          (m)  make every reasonable effort to prevent the issuance of any stop
order suspending the effectiveness of the registration statement or of any order
preventing or suspending the use of any preliminary prospectus and, if any such
order is issued, to obtain the withdrawal of any such order as soon as
practicable;

          (n)  if requested by the managing underwriter or agent or any Holder
of Registrable Securities covered by the registration statement, promptly
incorporate in a prospectus supplement or post-effective amendment such
information as the managing underwriter or agent or such Holder reasonably
requests to be included therein, including, with respect to the number

                                                                              26

of Registrable Securities being sold by such Holder to such underwriter or
agent, the purchase price being paid therefor by such underwriter or agent and
with respect to any other terms of the underwritten offering of the Registrable
Securities to be sold in such offering; and make all required filings of such
prospectus supplement or post-effective amendment as soon as practicable after
being notified of the matters incorporated in such prospectus supplement or
post-effective amendment;

          (o)  cooperate with the Holders of Registrable Securities covered by
the registration statement and the managing underwriter or agent, if any, to
facilitate the timely preparation and delivery of certificates (not bearing any
restrictive legends) representing securities to be sold under the registration
statement, and enable such securities to be in such denominations and registered
in such names as the managing underwriter or agent, if any, or such Holders may
request;

          (p)  obtain for delivery to the Holders of Registrable Securities
being registered and to the underwriter or agent an opinion or opinions from
counsel for the Company in customary form and in form, substance and scope
reasonably satisfactory to such Holders, underwriters or agents and their
counsel;

          (q)  cooperate with each seller of Registrable Securities and each
underwriter or agent participating in the disposition of such Registrable
Securities and their respective counsel in connection with any filings required
to be made with the NASD; and

          (r)  use its commercially reasonable best efforts to make available
the executive officers of the Company to participate with the Holders of
Registrable Securities and any underwriters in any "road shows" or other selling
efforts that may be reasonably requested by the Holders in connection with the
methods of distribution for the Registrable Securities.

          SECTION IV.4  Information Supplied.  The Company may require each
                        --------------------
seller of Registrable Securities as to which any registration is being effected
to furnish the Company with such information regarding such seller and pertinent
to the disclosure requirements relating to the registration and the distribution
of such securities as the Company may from time to time reasonably request.

          SECTION IV.5  Restrictions on Disposition.  Each Holder agrees that,
                        ---------------------------
upon receipt of any notice from the Company of the happening of any event of the
kind described in Section 4.3(f), such Holder will forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such Holder's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 4.3(f), and,
if so directed by the Company, such Holder will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the prospectus covering such Registrable Securities
current at the time of receipt of such notice.  In the event the Company shall
give any such notice, the period mentioned in Section 4.3(b) shall be extended
by the number of days during the period from and including the date of the
giving of such notice pursuant to Section 4.3(f) and to and including the date
when each seller of
<PAGE>

                                                                              27

Registrable Securities covered by such registration statement shall have
received the copies of the supplemented or amended prospectus contemplated by
Section 4.3(f).

          SECTION IV.6  Indemnification.  (a)  In the event of any registration
                        ---------------
of any securities of the Company under the Securities Act pursuant to Section
4.1 or 4.2, the Company shall, and it hereby does, indemnify and hold harmless,
to the extent permitted by law, the seller of any Registrable Securities covered
by such registration statement, each Affiliate of such seller and their
respective directors, officers, members or general and limited partners (and any
director, officer, and controlling Person of any of the foregoing), each Person
who participates as an underwriter in the offering or sale of such securities
and each other Person, if any, who controls such seller or any such underwriter
within the meaning of the Securities Act (collectively, the "Indemnified
                                                             -----------
Parties"), against any and all losses, claims, damages or liabilities, joint or
-------
several, actions or proceedings (whether commenced or threatened) in respect
thereof ("Claims") and expenses (including reasonable attorney's fees and
          ------
reasonable expenses of investigation) to which such Indemnified Party may become
subject under the Securities Act, common law or otherwise, insofar as such
Claims or expenses arise out of, relate to or are based upon (a) any untrue
statement or alleged untrue statement of any material fact contained in any
registration statement under which such securities were registered under the
Securities Act, any preliminary, final or summary prospectus contained therein,
or any amendment or supplement thereto, or (b) any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein (in the case of a prospectus, in light of the
circumstances under which they were made) not misleading; provided, that the
                                                          --------
Company shall not be liable to any Indemnified Party in any such case to the
extent that any such Claim or expense arises out of, relates to or is based upon
any untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement or amendment or supplement thereto or in any
such preliminary, final or summary prospectus in reliance upon and in conformity
with written information furnished to the Company by or behalf of such seller
specifically stating that it is for use in the preparation thereof.  Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of any Indemnified Party and shall survive the transfer of
securities by any seller.

          (b)  The Company may require, as a condition to including any
Registrable Securities in any registration statement filed in accordance with
Section 4.2 or 4.3 herein, that the Company shall have received an undertaking
reasonably satisfactory to it from the prospective seller of such Registrable
Securities or any underwriter to indemnify and hold harmless (in the same manner
and to the same extent as set forth in Section 4.6(a)) the Company and all other
prospective sellers or any underwriter, as the case may be, with respect to any
untrue statement or alleged untrue statement in or omission or alleged omission
from such registration statement, any preliminary, final or summary prospectus
contained therein, or any amendment or supplement thereto, if such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information furnished to the
Company by or on behalf of such seller or underwriter specifically stating that
it is for use in the preparation of such registration statement, preliminary,
final or summary prospectus or amendment or supplement, or a document
incorporated by reference into any of the foregoing.  Such indemnity shall
remain in full force and effect regardless of any investigation made by or on
behalf of the Company or any of the prospective sellers, or any of their
respective Affiliates,
<PAGE>

                                                                              28

directors, officers or controlling Persons and shall survive the transfer of
securities by any seller. In no event shall the liability of any selling Holder
of Registrable Securities hereunder be greater in amount than the dollar amount
of the proceeds received by such Holder upon the sale of the Registrable
Securities giving rise to such indemnification obligation.

          (c)  Promptly after receipt by an indemnified party hereunder of
written notice of the commencement of any action or proceeding with respect to
which a claim for indemnification may be made pursuant to this Section 4.6, such
indemnified party will, if a claim in respect thereof is to be made against an
indemnifying party, give written notice to the latter of the commencement of
such action or proceeding; provided, that the failure of the indemnified party
                           --------
to give notice as provided herein shall not relieve the indemnifying party of
its obligations under Section 4.6, except to the extent that the indemnifying
party is materially prejudiced by such failure to give notice.  In case any such
action or proceeding is brought against an indemnified party, unless in such
indemnified party's reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist in respect of such action or
proceeding (in which case the indemnified party shall have the right to assume
or continue its own defense and the indemnifying party shall be liable for any
reasonable expenses therefor, but in no event will bear the expenses for more
than one firm of counsel for all indemnified parties in each jurisdiction who
shall be approved by the majority of the participating Holders in the
registration in respect of which such indemnification is sought), the
indemnifying party will be entitled to participate in and to assume the defense
thereof (at its expense), jointly with any other indemnifying party similarly
notified to the extent that it may wish, with counsel reasonably satisfactory to
such indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation and shall have no
liability for any settlement made by the indemnified party without the consent
of the indemnifying party, such consent not to be unreasonably withheld.  No
indemnifying party will settle any action or proceeding or consent to the entry
of any judgment without the prior written consent of the indemnified party,
unless such settlement or judgment (i) includes as an unconditional term thereof
the giving by the claimant or plaintiff of a release to such indemnified party
from all liability in respect of such action or proceeding and (ii) does not
involve the imposition of equitable remedies or the imposition of any
obligations on such indemnified party and does not otherwise adversely affect
such indemnified party, other than as a result of the imposition of financial
obligations for which such indemnified party will be indemnified hereunder.

          (d)  (i) If the indemnification provided for in this Section 4.6 from
the indemnifying party is unavailable to an indemnified party hereunder in
respect of any Claim or expenses referred to herein, then the indemnifying
party, in lieu of indemnifying such indemnified party, shall contribute to the
amount paid or payable by such indemnified party as a result of such Claim or
expenses in such proportion as is appropriate to reflect the relative fault of
the indemnifying party and indemnified party in connection with the actions
which resulted in such Claim or expenses, as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of
<PAGE>

                                                                              29

a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party under this Section 4.6(d) as a result of the Claim and
expenses referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such party in connection with any action or
proceeding.

          (ii) The parties hereto agree that it would not be just and equitable
if contribution pursuant to this Section 4.6(d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in Section 4.6(d)(i).  No Person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any Person who was not
guilty of such fraudulent misrepresentation.

          (e)  Indemnification similar to that specified in this Section 4.6
(with appropriate modifications) shall be given by the Company and each seller
of Registrable Securities with respect to any required registration or other
qualification of securities under any Law or with any governmental authority
other than as required by the Securities Act.

          (f)  The obligations of the parties under this Section 4.6 shall be in
addition to any liability which any party may otherwise have to any other party.

          SECTION IV.7  Required Reports.  The Company covenants that it will
                        ----------------
file the reports required to be filed by it under the Securities Act and the
Exchange Act (or, if the Company is not required to file such reports, it will,
upon the request of any Holder, make publicly available such information), and
it will take such further action as any Holder may reasonably request, all to
the extent required from time to time to enable such Holder to sell shares of
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act,
as such Rule may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the SEC.  Upon the request of any Holder, the
Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.

          SECTION IV.8  Selection of Counsel.  In connection with any
                        --------------------
registration of Registrable Securities pursuant to Sections 4.1 and 4.2 hereof,
the Holders of a majority of the Registrable Securities covered by any such
registration may select one counsel to represent all Holders of Registrable
Securities covered by such registration; provided, however, that in the event
                                         --------  -------
that the counsel selected as provided above is also acting as counsel to the
Company in connection with such registration, the remaining Holders shall be
entitled to select one additional counsel to represent all such remaining
Holders.

          SECTION IV.9  Holdback Agreement.  If any registration hereunder shall
                        ------------------
be in connection with an underwritten public offering, each Holder agrees not to
effect any public sale or distribution, including any sale pursuant to Rule 144
under the Securities Act, of any Equity Securities of the Company (in each case,
other than as part of such underwritten public offering), within 7 days before,
or subject to Section 4.2(g) in the case of a requested registration that has
been postponed pursuant to clause (i) thereof, 180 days (or such lesser period
as the managing

                                                                              30

underwriters may permit) after, the effective date of such registration (except
as part of such registration), and the Company hereby also agrees and agrees to
use its commercially reasonable efforts to have each other holder of any Equity
Security of the Company purchased from the Company (at any time other than in a
public offering) to so agree.

          SECTION IV.10  No Inconsistent Agreements.  The Company represents and
                         --------------------------
warrants that it will not enter into, or cause or permit any of its Subsidiaries
to enter into, any agreement which conflicts with or limits or prohibits the
exercise of the rights granted to the Holders of Registrable Securities in this
Article IV.


                       ARTICLE V           EQUITY PURCHASE RIGHTS
                                           ----------------------

          SECTION V.1    Equity Purchase Rights. (a) The Company hereby grants
                         ----------------------
to the Investor Stockholder, so long as any shares of Preferred Stock are
outstanding, the right to purchase its Pro Rata Portion of all or any part of
New Securities which the Company may, from time to time, propose to sell or
issue. The number or amount of New Securities which the Investor Stockholder may
purchase pursuant to this Section 5.1(a) shall be referred to as the "Equity
                                                                      ------
Purchase Shares". The equity purchase right provided in this Section 5.1(a)
---------------
shall apply at the time of issuance of any right, warrant or option or
convertible or exchangeable security and not to the conversion, exchange or
exercise thereof; provided, that with respect to any such right, warrant, option
                  --------
or convertible or exchangeable security, the Investor Stockholder shall have the
right to purchase its Pro Rata Portion of a series of preferred stock of the
Company with terms identical to the Preferred Stock except that the conversion
price shall be the exercise, conversion or exchange price of such right,
warrant, option or convertible or exchangeable security.

          (b)  The Company shall give written notice of a proposed issuance or
sale described in Section 5.1(a) to the Investor Stockholder within two Business
Days following any meeting of the Board at which any such issuance or sale is
approved. Such notice (the "Issuance Notice") shall set forth the material
                            ---------------
terms and conditions of such proposed transaction, including the name of any
proposed purchaser(s), the proposed manner of disposition, the number or amount
and description of the shares proposed to be issued and the proposed purchase
price per share, including a description of any non-cash consideration
sufficiently detailed to permit valuation thereof. Such notice shall also be
accompanied by any written offer from the prospective purchaser to purchase such
New Securities. The Issuance Notice shall be received by the Investor
Stockholder at least 20 days prior to the proposed issuance or sale.

          (c)  At any time during the 20-day period following the receipt of an
Issuance Notice, the Investor Stockholder shall have the right to irrevocably
elect to purchase up to the number of the Equity Purchase Shares at the purchase
price set forth in the Issuance Notice (or if such price includes property other
than cash, the amount in cash equal to the Fair Market Value of such other
property) and upon the other terms and conditions specified in the Issuance
Notice by delivering a written notice to the Company.  Except as provided in the
following sentence, such purchase shall be consummated concurrently with the
consummation of the issuance or sale described in the Issuance Notice.  The
closing of any purchase by the Investor Stockholder may

                                                                              31


be extended beyond the closing of the transaction described in the Issuance
Notice to the extent necessary to obtain required governmental approvals and
other required approvals and the Company and the Investor Stockholder shall use
their respective best efforts to obtain such approvals.

          (d   If the Investor Stockholder does not elect pursuant to Section
5.1(c) to purchase any of the Equity Purchase Shares, the Company shall be free
to complete the proposed issuance or sale described in the Issuance Notice on
terms no less favorable to the Company than those set forth in the Issuance
Notice; provided, that (x) such issuance or sale is closed within 90 days after
        --------
the expiration of the 20-day period described in Section 5.1(c) and (y) the
price at which the New Securities are transferred must be equal to or higher
than the purchase price described in the Issuance Notice. Such periods within
which such issuance or sale must be closed shall be extended to the extent
necessary to obtain required governmental approvals and other required approvals
and the Company shall use its commercially reasonable efforts to obtain such
approvals.


                           ARTICLE VI    STANDSTILL
                                         ----------

          SECTION VI.1  Acquisition of Additional Voting Securities.  (a)
                        -------------------------------------------
During the Standstill Period, except as provided below in this Section 6.1, the
Investor Stockholder covenants and agrees with the Company that it shall not,
and shall cause each of its Affiliates not to, directly or indirectly, acquire,
offer or propose to acquire or agree to acquire, whether by purchase, tender or
exchange offer, through the acquisition of control of another Person (including
by way of merger or consolidation), by joining a partnership, syndicate or other
Group or otherwise, the beneficial ownership of any additional Voting Securities
if following such proposed acquisition (an "Acquisition") the Investor
                                            -----------
Stockholder together with its Affiliates would beneficially own a number of
Voting Securities exceeding the Permitted Ownership Percentage (except (i) by
way of stock dividends, stock reclassifications or other distributions or
offerings made available and, if applicable, exercised on a pro rata basis, to
holders of Equity Securities of the Company generally, (ii) Equity Securities
acquired from the Company (including Conversion Shares and shares of Series E
Preferred Stock subject to the Option), and (iii) Voting Securities acquired
upon the exercise of the Investor Stockholder's rights under Article V) (the
"Acquisition Restrictions"); provided, however, that the foregoing Acquisition
 ------------------------    --------  -------
Restrictions shall not apply to any Acquisition that is approved by a majority
of the Directors, excluding for the purposes of such approval any Investor
Directors.

          (b   The foregoing Acquisition Restrictions will not apply if either
(i) a third party who is not an Affiliate of the Investor Stockholder or any of
its Affiliates (a "Third Party", which term shall include any Group, other than
                   -----------
a Group which includes the Investor Stockholder or any of its Affiliates as a
member) commences a tender or exchange offer for more than 50% of the
outstanding Voting Securities and the Board does not recommend against the
tender or exchange offer within ten Business Days after the commencement thereof
(which, in the case of an exchange offer, shall be deemed to be the effective
date of the registration statement relating to the securities offered in such
exchange offer or, if permitted under the Exchange Act, such earlier date
selected by the offeror for commencement of the exchange offer) or such longer

                                                                              32

period as shall then be permitted under SEC rules, or (ii) a Third Party
acquires beneficial ownership of 15% of the outstanding Voting Securities (other
than as a result of purchases of such securities from the Company) and publicly
discloses a possible intention to seek control of the Company or to engage in a
transaction that would result in a Change of Control of the Company.

          (c   Upon a repurchase or redemption of Equity Securities by the
Company that, by reducing the number of outstanding Equity Securities, increases
the Ownership Percentage to an amount in excess of the then-applicable Permitted
Ownership Percentage, none of the Investor Stockholder or its Affiliates shall
be required to dispose of Equity Securities beneficially owned by them;
provided, however, that in such event, none of the Investor Stockholder or its
--------  -------
Affiliates may purchase additional Equity Securities until such time as the
Ownership Percentage is less than the then-applicable Permitted Ownership
Percentage.

          (d   If at any time the Investor Stockholder or any of its Affiliates
become aware that the Investor Stockholder and its Affiliates beneficially own
in the aggregate more than the Permitted Ownership Percentage, then the Investor
Stockholder shall, as soon as is reasonably practicable (but in no manner that
would require the Investor Stockholder or any such Affiliate to incur liability
under Section 16(b) of the Exchange Act) take all action necessary to reduce the
amount of Equity Securities beneficially owned by it and its Affiliates to an
amount not greater than the Permitted Ownership Percentage in effect at such
time.

          SECTION VII.1 Investor Stockholder Indemnification; Reimbursement of
                        ------------------------------------------------------
Expenses.  The Company agrees to indemnify and hold harmless the Investor

Stockholder, its respective directors and officers and its Affiliates (and the
directors, officers, partners, Affiliates and controlling persons thereof, each,
an "Investor Stockholder Indemnitee") from and against any and all liability,

including, without limitation, all obligations, costs, fines, claims, actions,
injuries, demands, suits, judgments, proceedings, investigations, arbitrations
(including stockholder claims, actions, injuries, demands, suits, judgments,
proceedings, investigations or arbitrations) and expenses, including, without
limitation, accountant's and attorney's fees and expenses (together the
"Losses"), incurred by the Investor Stockholder or an Investor Stockholder
 ------
Indemnitee before or after the date of this Agreement and arising out of,

Stock Purchase Agreement, the Stockholders Agreement, the Certificate of
Designation and the Voting Agreement, dated as of December 20, 1999, among the
Investor Stockholder and certain stockholders of the Company, (iii) any
litigation to which the Investor Stockholder or a Stockholder Indemnitee is made
a party in its capacity as a stockholder or owner of securities (or a partner,
director, officer, Affiliate or controlling person of the Investor Stockholder)
of the Company or (iv) any franchise taxes imposed on the Investor Stockholder.
The Company also agrees to reimburse each Investor Stockholder Indemnitee for
any reasonable expenses incurred by such Investor Stockholder Indemnitee in
connection with the maintenance of its books and records, preparation of tax
returns and delivery of tax information to its partners in connection with the
Investor Stockholder's investment in the Company.

          SECTION VII.2 Termination.  Subject to Section 3.1(b)(i), (x) the
                        -----------
provisions of this Agreement (other than Articles II, IV and VII) shall
terminate at such time as the Investor Stockholder shall own, together with its
Affiliates, less than 5% of the outstanding Common Stock as converted and (y)
the provisions of Article II shall terminate as provided in Section 2.7.
Article IV of this Agreement (other than Section 4.6 thereof) shall terminate at
such time as there shall be no Registrable Securities outstanding.  Section 7.1

from any liability for the breach of any of the agreements set forth in this
Agreement.

          SECTION VII.3 Amendments and Waivers.  Except as otherwise provided
                        ----------------------
herein, no modification, amendment or waiver of any provision of this Agreement
shall be effective against the Company or any Holder unless such modification,
amendment or waiver is approved in writing by the Company and each such Holder.
The failure of any party to enforce any of the provisions of this Agreement
shall in no way be construed as a waiver of such provisions and shall not affect
the right of such party thereafter to enforce each and every provision of this
Agreement in accordance with its terms.

          SECTION VII.4 Successors, Assigns and Transferees.  This Agreement
                        -----------------------------------

Purchaser and its Affiliates may assign their respective rights and obligations

          SECTION VII.5 Notices.  All notices required or permitted hereunder

                        ------------------
after the date hereof, the parties agree to cooperate with each other, and at

or documents and to take all such further action as the other party may
reasonably request in order to evidence or effectuate the consummation of the
transactions contemplated hereby and to otherwise carry out the intent of the
parties hereunder.

          SECTION VII.7 Entire Agreement.  Except as otherwise expressly set
                        ----------------
forth herein, this document and the Stock Purchase Agreement embody the complete
agreement and understanding among the parties hereto with respect to the subject
matter hereof and supersede and preempt any prior understandings, agreements or
representations by or among the parties, written or oral, that may have related
to the subject matter hereof in any way.

          SECTION VII.8 Delays or Omissions.  It is agreed that no delay or
                        -------------------
omission to exercise any right, power or remedy accruing to any party, upon any
breach, default or noncompliance by another party under this Agreement, shall
impair any such right, power or remedy, nor shall it be construed to be a waiver
of any such breach, default or noncompliance, or any acquiescence therein, or of
or in any similar breach, default or noncompliance thereafter occurring. It is
further agreed that any waiver, permit, consent or approval of any kind or
character on the part of any party hereto of any breach, default or
noncompliance under this Agreement or any waiver on such party's part of any
provisions or conditions of this Agreement, must be in writing and shall be
effective only to the extent specifically set forth in such writing. All
remedies, either under this Agreement, by law, or otherwise afforded to any
party, shall be cumulative and not alternative.

          SECTION VII.9 Governing Law; Jurisdiction; Waiver of Jury Trial.
                        -------------------------------------------------
This Agreement shall be governed in all respects by the laws of the State of New
York. No suit, action or proceeding with respect to this Agreement may be
brought in any court or before any similar authority other than in a court of
competent jurisdiction in the State of New York, and the
<PAGE>

                                                                              35

parties hereto hereby submit to the exclusive jurisdiction of such courts for
the purpose of such suit, proceeding or judgment. The parties hereto hereby
irrevocably waives any right which they may have had to bring such an action in
any other court, domestic or foreign, or before any similar domestic or foreign
authority. Each of the parties hereto hereby irrevocably and unconditionally
waives trial by jury in any legal action or proceeding in relation to this
Agreement and for any counterclaim therein.

          SECTION VII.10 Severability.  Whenever possible, each provision of
                         ------------
this Agreement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be
invalid, illegal or unenforceable in any respect under any applicable law or
rule in any jurisdiction, such invalidity, illegality or unenforceability shall
not affect any other provision or any other jurisdiction, but this Agreement
shall be reformed, construed and enforced in such jurisdiction as if such
invalid, illegal or unenforceable provision had never been contained herein.

          SECTION VII.11 Effective Date.  This Agreement shall become effective
                         --------------
immediately upon the First Closing.

          SECTION VII.12 Enforcement.  Each party hereto acknowledges that money
                         -----------
damages would not be an adequate remedy in the event that any of the covenants
or agreements in this Agreement are not performed in accordance with its terms,
and it is therefore agreed that in addition to and without limiting any other
remedy or right it may have, the non-breaching party will have the right to an
injunction, temporary restraining order or other equitable relief in any court
of competent jurisdiction enjoining any such breach and enforcing specifically
the terms and provisions hereof.

          SECTION VII.13 Titles and Subtitles.  The titles of the sections and

to be considered in construing this Agreement.

          SECTION VII.14 No Recourse.  Notwithstanding anything that may be
                         -----------
expressed or implied in this Agreement, the Company and each Holder covenant,
agree and acknowledge that no recourse under this Agreement or any documents or
instruments delivered in connection with this Agreement shall be had against any
current or future director, officer, employee, general or limited partner or
member of the Investor Stockholder or of any Affiliate or assignee thereof,
whether by the enforcement of any assessment or by any legal or equitable
proceeding, or by virtue of any statute, regulation or other applicable law, it
being expressly agreed and acknowledged that no personal liability whatsoever
shall attach to, be imposed on or otherwise be incurred by any current or future
officer, agent or employee of the Investor Stockholder or any current or future
member of the Investor Stockholder or any current or future director, officer,
employee, partner or member of the Investor Stockholder or of any Affiliate or
assignee thereof, as such for any obligation of the Investor Stockholder under
this Agreement or any documents or instruments delivered in connection with this
Agreement for any claim based on, in respect of or by reason of such obligations
or their creation.
