         1.4   CALL OPTION. Each of the Management Stockholders agrees, for
themselves and all Management Parties who subsequently acquire or hold Shares
previously held by such Management Stockholder (including Transferees of such
Management Stockholder), that the Company will have a call option (the "CALL
OPTION") on all Shares held by any Management Stockholder or Management Party,
including all Common Shares issuable upon exercise of any Employee Options (the
"CALLABLE SECURITIES"), upon the voluntary termination by such Management
Stockholder of such Management Stockholder's employment with the Company (each,
a "CALL EVENT"); PROVIDED that the Company may provide that the Company may
exercise the Call Option through the purchase of the Management Stockholder's
Employee Options. The Call Option will expire: (a) with respect to Management
Stockholders who began employment with the Company prior to January 1, 2001, (i)
as to 50% of the Shares owned, or Common Shares issuable upon exercise of any
Employee Options owned, by each such Person upon the closing of the Initial
Public Offering and (ii) as to 25% of the Shares owned, or Common Shares
issuable upon exercise of any Employee Options owned, by each such Person upon
each of the first two anniversaries of the date of the closing of the Initial
Public Offering, or (b) with respect to Management Stockholders who began
employment with the Company on or after January 1, 2001, (i) as to 25% of the
Shares owned, or Common Shares issuable upon exercise of any Employee Options
owned, by each such Person upon the closing of the Initial Public Offering and
(ii) as to 25% of the Shares owned, or Common Shares issuable upon exercise of
any Employee Options owned, by each such Person upon each of the first three
anniversaries of the date of the closing of the Initial Public Offering. Upon
the occurrence of a Call Event, the Company may exercise the Call Option by
written notice (an "OPTION NOTICE") of its election to do so delivered to the
Management Stockholder (or, if different, the then current holder of the Shares)
within the later of (1) ninety (90) days after such Call Event, (2) the date of
expiration of the options, in the event of an election to purchase Employee
Options and (3) thirty (30) days after the Management Stockholder's exercise of
Employee Options, in the case of an election to purchase Common Shares issuable
upon exercise of options to acquire Common Shares from the Company, and, upon
the giving of such notice, the Company will be obligated to purchase, and the
Management Stockholder (or, if different, the then current holder of the Shares)
("SELLER") will be obligated to sell, all or any lesser portion indicated in the
Option

                                       4

<Page>

Notice of the Callable Securities owned at the time of the Call Event by the
Seller. The consideration for the Callable Securities referred to in the
preceding sentence shall be the Management Stockholder's Cost of such Callable
Securities.

         The closing for all purchases and sales of Callable Securities pursuant
to this Section 1.4 will be at the principal executive offices of the Company on
the 60th day after the giving of the Option Notice. The applicable purchase
price for the Callable Securities will be paid in cash or by cashier's check.
The Seller will cause the Callable Securities to be delivered to the Company at
the closing free and clear of all liens, charges or encumbrances of any kind
except those which shall continue to apply to such Shares by the terms of this
Agreement. Such Seller will take all such actions as the Company reasonably
requests to vest in the Company title to the Callable Securities free of any
lien, charge or encumbrance incurred by or through the Seller.

         Notwithstanding any other section of this Agreement, in the event a
Management Stockholder's employment with the Company is terminated other than
through the Management Stockholder's Retirement from the Company, all of the
Management Stockholder's Employee Options may be exercisable for three months
following such termination and the exercise price may be paid at the Management
Stockholder's election (a) by cash or cashiers check, or (b) by surrender of
Common Shares or Employee Options (other than Common Shares or Employee Options
that are subject to the Call Option) ("NET ISSUANCE") as determined below. If
the Management Stockholder elects the Net Issuance method, the Company will
issue Shares in accordance with the following formula:

               X    =     Y(A-B)
                          ------
                             A

         Where:

               X =  the number of Shares to be issued to the Stockholder

               Y =  the number of Shares requested to be exercised under this
                    Agreement

               A =  the Fair Market Value of one (1) Share

               B =  the exercise price

Notwithstanding, any other section of this Agreement, in the event a Management
Stockholder's employment with the Company is terminated through the Management
Stockholder's Retirement from the Company, all of the Management Stockholder's
Employee Options may be exercised at any time and from time to time until the
expiration of such Employee Options.

following meanings:

similar events), with respect to Common Shares which were retained by the holder
thereof pursuant to Section 2.2(c) of the Merger Agreement, (2) the Fair Market
Value of such Common Shares at the time such Common Shares were originally
acquired from the Company, with respect to Common Shares which were acquired
pursuant to the exercise of Options (as defined in the Merger Agreement)

Agreement, or (3) the consideration originally paid to the Company for such
Common Shares, with respect to Common Shares which are otherwise acquired, (y)

the Nasdaq National Market, its last reported sale price on the Nasdaq National
Market or, if no such reported sale takes place on such date, the average of the
closing bid and asked prices; (b) if the Common Stock is publicly traded and is
then listed on a national securities exchange but is not quoted on the Nasdaq
National Market, the last reported sale price or, if no such reported sale takes
place on such date, the average of the closing bid and asked prices on the
principal national securities exchange on which the Common Stock is listed or
admitted to trading; (c) if such Common Stock is publicly traded but is not
quoted on the Nasdaq National Market nor listed or admitted to trading on a

         "RETIREMENT" means retirement pursuant to the Company's standard
retirement policy in effect from time to time but in no event prior to the age
of 65, unless otherwise agreed upon by the Stockholder and the Company's Board
of Directors.

         1.5   TAX TREATMENT. The attachment of restrictions to the Shares held
by the Management Stockholders and the subsequent lapse of those restrictions
(the "EXCHANGE RESTRICTIONS") is not intended to constitute a transfer of
property in connection with the performance of services by the Management
Stockholders within the meaning of Section 83 of the Internal Revenue Code of
1986, as amended (the "CODE"). Accordingly, the Company will not report
compensation to the Management Stockholders at any time with respect to the
Exchange Restrictions unless required to by applicable law.

statement with respect to each Demand Registration and use its best efforts to
cause the same to be declared effective as promptly as practicable following
such Demand, but not later than one hundred twenty (120) days thereafter. Unless
all of the Registrable Shares covered by the registration statement have earlier
been sold or withdrawn from sale, the Company shall keep any such Registration
Statement effective for a period of at least one hundred eighty (180) days after
such registration statement is first declared effective plus a period equal to
(x) any period during which the Selling Holders are prohibited from making sales
because of any stop order, injunction or other order or requirement of the
Commission or any other governmental agency or court plus (y) any Demand
Suspension Period (as defined below) plus (z) any holdback period pursuant to
Section 2.7 that occurs while the registration statement is effective (the
"DEMAND PERIOD") and a registration will not count as a Demand Registration
unless it is declared effective by the Commission and remains effective until
the earlier of such time as all of the Registrable Shares included in such
registration have been sold or disposed of or withdrawn from sale by the Selling
Holders or the expiration of the Demand Period or, if the registration remains
effective for a shorter period, the Selling Holders have sold at least eighty
percent (80%) of their Registrable Shares included in such Demand Registration.
In addition, a request for registration shall not be deemed to constitute a
Demand Registration if: (a) the conditions to closing specified in the

                                       10

<Page>

purchase agreement or underwriting agreement entered into in connection with
such Demand Registration are not satisfied other than by reason of some act or
omission by the Selling Holders; (b) the Company voluntarily takes any action
that would result in the Selling Holders not being able to sell such Registrable
Shares covered thereby during the Demand Period; (c) after it has become

injunction or other order or requirement of the Commission or other governmental
agency or court and such order, injunction or requirement is not promptly
withdrawn or lifted, and such Demand Registration has not otherwise remained
effective for the Demand Period (including effective periods both before and
after the order, injunction or requirement is made or imposed); or (d) such
Demand Registration does not involve an underwritten offering and the Selling
Holders determine not to proceed following any delay imposed hereunder by the
Company; PROVIDED, HOWEVER, that prior to such a delay under this clause (d),
the Selling Holders have not sold more than eighty percent (80%) of the
Registrable Shares included in such Demand Registration. Notwithstanding the
foregoing, the Company may, at any time, delay the filing or delay or suspend
the effectiveness of the Demand Registration or, without suspending such
effectiveness, instruct the Selling Holders not to sell any securities included
in the Demand Registration, if the Company shall have determined in good faith
(as evidenced by a resolution of the Company's Board of Directors delivered to
the Selling Holders) that proceeding with the Demand Registration at such time
may have a material adverse effect on the Company or the Company shall have
determined upon the advice of counsel that as a result of complying with such
Demand it would be required to disclose any material actions proposed to be
taken by the Company in good faith and for valid business reasons, including,
without limitation, the acquisition or divestiture of assets, which disclosure
may have a material adverse effect on the Company or on such actions (a "DEMAND
SUSPENSION PERIOD"), by providing the Selling Holders with written notice of
such Demand Suspension Period and the reasons therefor. The Company shall use
its reasonable best efforts to provide such notice at least ten (10) days prior
to the commencement of such a Demand Suspension Period; PROVIDED, HOWEVER, that
in any event the Company shall provide such notice no later than the
commencement of such Demand Suspension Period; and provided, further, that in no
event shall the Demand Suspension Periods exceed a total of sixty (60) days in
any twelve (12) month period.

         The Company further agrees to supplement or amend such registration
statement with respect to such Demand Registration, as required by the
registration form utilized by the Company or by the instructions applicable to
such registration form or by the Securities Act for the registration of
securities or as reasonably requested (which request shall result in the filing
of a supplement or amendment subject to approval thereof by the Company, which
approval shall not be unreasonably withheld) by any Selling Holder or any
managing underwriter of Registrable Shares to which such Demand Registration
relates, and the Company agrees to furnish to the Selling Holders (and any
managing underwriter) copies, in substantially the form proposed to be used
and/or filed, of any such supplement or amendment prior to the use thereof
and/or filing thereof with the Commission. The Company shall amend or supplement
the registration statement with respect to such Demand Registration no less
frequently than every forty five (45) days to update the list of Selling Holders
pursuant to written requests by such Holders.

               2.2.3  INCLUSION OF REGISTRABLE SHARES. Any written request for a
Demand shall specify the number of Registrable Shares to be registered and the
intended methods of

                                       11

<Page>

disposition thereof. Within ten (10) days after receipt of such Demand, the
Company shall give written notice of such registration request to all Holders,
as applicable, which have not made the Demand, and, subject to the limitations
set forth elsewhere herein, the Company shall include in such registration all
Registrable Shares with respect to which the Company has received written
requests for inclusion therein within fifteen (15) days after the date on which
such notice is given. Each such request shall also specify the aggregate number
of Registrable Shares to be registered. The Company may also include in such
Demand Registration shares of Common Stock for the account of the Company and
any other Persons who hold shares of Common Stock.

               2.2.4  PRIORITY ON DEMAND REGISTRATIONS. If a Demand Registration
is an underwritten registration and the managing underwriters of such offering
determine that the aggregate number of (a) Registrable Shares of the Selling
Holders exercising their rights to participate in the Demand Registration on a
demand basis, pursuant to this Section 2.2; (b) Shares of the Company; and (c)
Shares of any other Persons entitled to participate in such Demand Registration,
in each case proposed to be included in such registration statement, exceeds the
maximum number of Shares that can reasonably be expected to be sold within a
price range acceptable to the Company and the Selling Holders, then the number
of shares to be offered for the account of the Company and for the account of
all such other Persons, other than holders of Registrable Shares who initiated
the demand, participating in such registration shall be reduced or limited pro
rata (and to zero, if necessary) in proportion to the respective number of
Shares requested to be registered to the extent necessary to reduce the total
number of Shares requested to be included in such registration statement to the
maximum number of Shares that can reasonably be expected to be included therein
and still satisfy such price requirement. If the foregoing market "cutback" does
not reduce the aggregate number of Shares proposed to be included in the
registration statement to the maximum number of Shares that can reasonably be
expected to be sold within the price range acceptable to the Company and the
Selling Holders, the Company shall further reduce the number of Shares to be
included in such registration pro rata among all such remaining Selling Holders
on the basis of the number of Registrable Shares requested to be included by all
such Selling Holders. Any request for registration with respect to which such a
market "cutback" with respect to such Selling Holders occurs shall be deemed to
constitute a Demand Registration for all purposes of this Article II; PROVIDED,
HOWEVER, that if any such market "cutback" occurs with respect to a Demand
Registration and all Selling Holders who initiated the Demand are not able to
sell at least eighty percent (80%) of the Registrable Shares which such Holders
proposed to sell pursuant to such Demand Registration, then, although such
request for registration will be effectuated, such request will not count
against the number of Demands to which the Purchaser Holders, the Management
Holders and the Financing Holders are entitled pursuant to Section 2.2 hereof.

               2.2.5  COMPLIANCE. Notwithstanding any other provisions hereof,
the Company shall use its reasonable best efforts to ensure that (a) any
registration statement filed in connection with a Demand Registration, and any
amendment thereto, and any prospectus forming a part thereof, and any supplement
thereto, complies in all material respects with the Securities Act and the rules
and regulations thereunder, (b) any registration statement filed in connection
with a Demand Registration, and any amendment thereto, does not, when it becomes
effective, contain 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 and (c) any

                                       12

<Page>

prospectus forming part of any registration statement filed in connection with a
Demand Registration, and any supplement to such prospectus, does not include an
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements, in the light of the circumstances under which
they are made, not misleading.

         2.3   PIGGYBACK REGISTRATION.

               2.3.1  RIGHT TO INCLUDE REGISTRABLE SHARES. If the Company at any
time proposes to register any of its equity securities under the Securities Act,
whether or not for sale for its own account, on a form and in a manner which
would permit registration of Registrable Shares for a public offering under the
Securities Act (other than on a registration statement (a) on Form S-4 or Form
S-8 or any successor form thereto or (b) filed in connection with an exchange
offer), the Company shall give written notice of the proposed registration to
each Holder at least fifteen (15) days prior to the filing thereof, and each
Holder shall have the right to request that all or any part of its Registrable
Shares of the same class or series of the equity securities proposed to be
registered by the Company be included in such registration by giving written
notice to the Company within ten (10) days after the giving of such notice by
the Company. If the registration statement is to cover an underwritten offering,
such Registrable Shares shall be included in the underwriting on the same terms
and conditions as the securities otherwise being sold through the underwriters.
Notwithstanding the foregoing, a Holder may not request the registration of its
Registrable Shares if such Shares may, at the time (or within thirty days
thereafter), be distributed to the public pursuant to Rule 144, or any other
similar provision hereafter adopted by the Commission.

               2.3.2  PRIORITY ON PIGGYBACK REGISTRATIONS.

                      (a) COMPANY REGISTRATIONS. If the registration is an
underwritten primary registration on behalf of the Company and the managing
underwriter(s) of such offering determine in their good faith judgment that the
aggregate number of securities, including Registrable Shares, of the Company
which all Holders and all other security holders of the Company, pursuant to
contractual rights to participate in such registration (the "OTHER HOLDERS"),
propose to include in such registration statement exceeds the maximum number of
securities, including Registrable Shares, that can reasonably be expected to be
sold in such offering without materially and adversely affecting the
marketability of the offering or the selling price to be obtained, the Company
will include in such registration, first, the shares of Common Stock or other
securities which the Company proposes to sell and, second, the Registrable
Shares of such Selling Holders and other securities to be sold for the account
of Other Holders, pro rata among all such Selling Holders and Other Holders,
taken together, on the basis of the number of Registrable Shares or other
securities of the Company requested to be included by all Selling Holders and
Other Holders who have requested that securities owned by them be so included
(it being agreed and understood, however, that such managing underwriter(s)
shall have the right to eliminate entirely the participation in such
registration of all Selling Holders and Other Holders).

                                       13

<Page>

                      (b) SELLING HOLDERS' REGISTRATION.

                          (i)    If the registration is being made pursuant to a
Demand by Purchaser Holders pursuant to Section 2.2 hereof, and the managing
underwriter(s) determine that the aggregate number of securities which all
Selling Holders, the Company and all Other Holders propose to include in such
registration exceeds the maximum number of securities that can reasonably be
expected to be sold within the price range acceptable to the Company and the
Purchaser Holders that are Selling Holders, the Company will include in such
registration, first, the Registrable Purchaser Shares of the Selling Holders
participating in such registration on a demand basis in accordance with Section
2.2.4 hereof, and, second, any securities to be sold for the account of the
Company, securities to be sold for the account of the Selling Holders that are
either Purchaser Holders or Management Holders or Financing Holders and that are
participating in such offering on a piggyback basis and any securities to be
sold for the account of the Other Holders electing to include securities in such
registration, PRO RATA among the Company, all such Selling Holders and all such
Other Holders, taken together, on the basis of the number of Shares or other
securities to be sold by the Company in the absence of such PRO RATION, the
number of Registrable Shares or other securities requested to be included by all
such Selling Holders and the number of Shares or other securities requested to
be included by all such Other Holders (it being agreed and understood, however,
that such managing underwriter(s) shall have the right to eliminate entirely the
participation therein of the Company and of all such Selling Holders and Other
Holders pursuant to the terms of this sentence).

                          (ii)   If the registration is being made pursuant to a
Demand by Management Holders pursuant to Section 2.2 hereof, and the managing
underwriter(s) determine that the aggregate number of securities which all
Selling Holders, the Company and all Other Holders propose to include in such
registration exceeds the maximum number of securities that can reasonably be
expected to be sold within the price range acceptable to the Company and the
Management Holders that are Selling Holders, the Company will include in such
registration, first, the Registrable Management Shares of the Selling Holders
participating in such registration on a demand basis in accordance with Section
2.2.4 hereof, and, second, any securities to be sold for the account of the
Company, securities to be sold for the account of the Selling Holders that are
either Purchaser Holders or Management Holders or Financing Holders and that are
participating in such offering on a piggyback basis and any securities to be
sold for the account of the Other Holders electing to include securities in such
registration, PRO RATA among the Company, all such Selling Holders and all such
Other Holders, taken together, on the basis of the number of Shares or other
securities to be sold by the Company in the absence of such PRO RATION, the
number of Registrable Shares or other securities requested to be included by all
such Selling Holders and the number of Shares or other securities requested to
be included by all such Other Holders (it being agreed and understood, however,
that such managing underwriter(s) shall have the right to eliminate entirely the
participation therein of the Company and of all such Selling Holders and Other
Holders pursuant to the terms of this sentence).

                          (iii)  If the registration is being made pursuant to a
Demand by Financing Holders pursuant to Section 2.2 hereof, and the managing
underwriter(s) determine that the aggregate number of securities which all
Selling Holders, the Company and

                                       14

<Page>

all Other Holders propose to include in such registration exceeds the maximum
number of securities that can reasonably be expected to be sold within the price
range acceptable to the Company and the Financing Holders that are Selling
Holders, the Company will include in such registration, first, the Registrable
Financing Shares of the Selling Holders participating in such registration on a
demand basis in accordance with Section 2.2.4 hereof, and, second, any
securities to be sold for the account of the Company, securities to be sold for
the account of the Selling Holders that are either Purchaser Holders or
Management Holders or Financing Holders and that are participating in such
offering on a piggyback basis and any securities to be sold for the account of
the Other Holders electing to include securities in such registration, PRO RATA
among the Company, all such Selling Holders and all such Other Holders, taken
together, on the basis of the number of Shares or other securities to be sold by
the Company in the absence of such PRO RATION, the number of Registrable Shares
or other securities requested to be included by all such Selling Holders and the
number of Shares or other securities requested to be included by all such Other
Holders (it being agreed and understood, however, that such managing
underwriter(s) shall have the right to eliminate entirely the participation
therein of the Company and of all such Selling Holders and Other Holders
pursuant to the terms of this sentence).

                      (c) OTHER HOLDERS' REGISTRATION. If the registration is an
underwritten secondary registration on behalf of any of the Other Holders
pursuant to demand registration rights and the managing underwriters determine
that the aggregate number of securities which all Selling Holders, the Company
and all Other Holders propose to include in such registration exceeds the
maximum number of securities that can reasonably be expected to be sold within
the price range acceptable to the Company and the Other Holders, the Company
will include in such registration, first, the securities to be sold for the
account of the Other Holders demanding registration (but only to the extent such
Other Holders are entitled to demand inclusion thereof pursuant to demand
registration rights), second, any securities to be sold for the account of the
Company, and, third, the Registrable Shares of such Selling Holders and other
securities to be sold for the account of the Other Holders electing to include
(but not being entitled pursuant to demand registration rights to demand
inclusion of) securities in such registration, pro rata among all such Selling
Holders and Other Holders, taken together, on the basis of the number of
Registrable Shares or other securities of the Company requested to be included
by all Selling Holders and such Other Holders who have requested that securities
owned by them be included (it being agreed and understood, however, that such
managing underwriter(s) shall have the right to eliminate entirely the
participation therein of all such Selling Holders and Other Holders with respect
to such securities since they are not entitled to demand inclusion of such
securities pursuant to demand registration rights).

                      (d) UNDERWRITERS. Registrable Shares proposed to be
registered and sold for the account of any Selling Holder pursuant to a
piggyback registration shall be sold to prospective underwriters selected or
approved by the Company, and on the terms and subject to the conditions of one
or more underwriting agreements negotiated between the Company, the Selling
Holders, if any, and/or Other Holders demanding registration and such
prospective underwriters. The Selling Holders shall be permitted to withdraw all
or a part of the Registrable Shares held by such Selling Holders which were to
be included in such piggyback registration at any time prior to the effective
date of such registration. The Company may withdraw any registration statement
for such registration at any time before it becomes effective, or postpone

                                       15

<Page>

the offering of securities, without obligation or liability to any Selling
Holder participating on a piggyback basis (except pursuant to Section 2.8
hereof).

         2.4   REGISTRATIONS ON FORM S-3. At such time as the Company shall have
qualified for the use of Form S-3, or any similar form or forms promulgated by
the Commission, the Holders shall each have the right to request an unlimited
number of registrations on Form S-3. Any such request shall be in writing, shall
specify the Registrable Securities intended to be sold or disposed of by the
Holders thereof, shall state the intended method of disposition of such
Registrable Securities by the Holder(s) requesting such registration and shall
relate to Registrable Securities having proposed gross cash offering proceeds
(prior to deduction of underwriters commissions and expenses, if any) of Two
Million Dollars ($2,000,000) or more for all Registrable Securities to be
included, on the basis of a reasonable (in light of the current market price)
proposed per share offering price. The Company shall be obligated to effect such
registration or registrations on Form S-3 as soon as practicable after receipt
of such request; PROVIDED, HOWEVER, that the Company shall not be obligated to
effect the filing of a registration pursuant to this Section 2.4: (a) during the
period starting with the date ninety (90) days prior to the Company's estimated
date of filing of, and ending on a date one hundred eighty (180) days following
the effective date of, a registration statement pertaining to a public offering
of Common Stock for the account of the Company, PROVIDED that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective and that, in the good faith judgment
of the Company's underwriter for an underwritten offering or of the Company's
Board of Directors for any other offering, an offering pursuant to such a
registration statement would interfere in any material respect with the
successful marketing (including pricing) of the Common Stock to be included in
the Company's proposed registration statement, or (b) if the Company's Board of
Directors shall determine in good faith that such filing will interfere in any
material respect with a pending or contemplated financing, merger, sale of
assets, recapitalization or other similar corporate action of the Company. In
the event the Company's obligations are abated pursuant to the foregoing
proviso, and if any of the Holders on whose behalf the requested registration
statement would be filed and who were unable to have all of the Registrable
Securities included in the Company's registration statement pursuant to Section
2.3 hereof and then want such registration statement to be filed, the Company
shall file such registration statement as promptly as practicable following (x)
one hundred eighty (180) days after the effective date of the registration
statement with respect to the offering referred to in clause (a) above, or (y)
the date on which the transactions referred to in clause (b) above shall have
been completed or abandoned (as the case may be), but not later than one hundred
twenty (120) days after the initial registration request notice was given;
PROVIDED FURTHER, HOWEVER, that the Company shall not be obligated to file and
cause to become effective (i) more than two (2) registrations on Form S-3 in any
one twelve (12) month period or (ii) any registration on Form S-3 within six (6)
months after the effective date of any previous registration statement filed
under Section 2.2 or Section 2.3, with respect to which all Holders who had
requested the inclusion of any such shares in a registration statement were
entitled to included in such registration statement all Registrable Securities
requested to be included therein. No registration pursuant to this Section 2.4
shall count as a Demand Registration pursuant to Section 2.2 hereof.

                                       16

         2.5   REGISTRATION STATEMENT. In connection with any registration of
Registrable Shares under the Securities Act pursuant to this Agreement, the
Company will furnish each Selling Holder and each underwriter, if any, with a
copy of the registration statement and all amendments thereto and will supply
each such Selling Holder with copies of any prospectus included therein
(including a preliminary prospectus and all amendments and supplements thereto),
in each case including all exhibits, and such other documents as may be
reasonably requested, in such quantities as may be reasonably necessary for the
purposes of the proposed sale or distribution covered by such registration (the
Company hereby consenting to the use in accordance with all applicable law of
each such registration statement (or amendment or post-effective amendment
thereto) and each such prospectus (or preliminary prospectus or supplement
thereto) by each such Selling Holder and the underwriters, if any, in connection
with the offering and sale of the Registrable Shares covered by such
registration statement or prospectus). The Company shall not, however, be
required to maintain the registration statement relating to a Demand
Registration and to supply copies of a prospectus for a period beyond the Demand
Period, and, at the end of such period, the Company may register any Registrable
Shares covered by such registration statement and not then sold or distributed.
In connection with any such registration of Registrable Shares, the Company
will, at the request of the managing underwriter with respect thereto (or, if
not an underwritten offering, at the request of Selling Holders holding a
majority of the Registrable Shares to be included in the registration) use its
reasonable best efforts to register or qualify such Registrable Shares for sale
under the securities laws of such states as is reasonably requested to permit
the distribution of such Registrable Shares and to use its reasonable efforts to
keep each such registration or qualification effective during the period such
registration statement is required to be kept effective and to do such other
acts or things reasonably necessary to enable the disposition in such
jurisdictions of the securities covered by the applicable registration statement
in accordance with applicable Blue Sky securities laws of such jurisdictions;
PROVIDED, HOWEVER, that the Company shall not be required in connection
therewith or as a condition thereof to qualify as a foreign corporation or to
execute a general consent to service of process in any jurisdiction or become
subject to taxation in any jurisdiction. In connection with any offering of
Registrable Shares registered pursuant to this Agreement, the Company shall (a)
furnish each Selling Holder, at the Company's expense and at least three (3)
business days prior to the sale of any Registrable Shares to the underwriters,
with unlegended certificates in a form eligible for deposit with The Depository
Trust Company representing ownership of the Registrable Shares which are sold
pursuant to the registration statement, in such denominations and registered in
such names as the managing underwriter, if any, or such Selling Holder shall
reasonably request, and (b) instruct the transfer agent and registrar of the
Common Stock to release any stop transfer orders with respect to the Registrable
Shares so sold.

         2.6   REGISTRATION PROCEDURES. In connection with the Company's
obligations to effect a registration pursuant to Sections 2.2, 2.3 and 2.4 (but
subject to the last sentence of Section 2.3.2(d) and provided that any time
periods set forth in this Section 2.6 regarding effective periods and the like
shall apply only in the event of a Demand Registration), the Company will as
expeditiously as is reasonably practicable:

               (a) prepare and file with the Commission as soon as practicable
(in the case of a Demand Registration) a registration statement with respect to
such Registrable Shares, on a form available for the sale of the Registrable
Shares by the Holders thereof in accordance

                                       17

<Page>

with the intended method or methods of distribution thereof and use its
commercially reasonable efforts to cause each such registration statement to
become and remain effective; PROVIDED, HOWEVER, that before filing a
registration statement or prospectus or any amendments or supplements thereto
(including documents that would be incorporated or deemed to be incorporated
therein by reference) and, whether or not filed pursuant to Section 2.2, 2.3 or
2.4, the Company will furnish to the Holders of the Registrable Shares covered
by such registration statement and the underwriters, if any, and any attorney,
accountant or other agent retained by the Holders of Registrable Shares covered
by such registration statement, copies of all such documents proposed to be
filed, which documents will be subject to the review and comment of such
Holders, such counsel and underwriters, if any. The Company will not file any
registration statement or any amendment thereto or any prospectus or any
supplement thereto in connection with a Demand Registration pursuant to Section
2.2 (including such documents incorporated by reference and proposed to be filed
after the initial filing of the registration statement) to which the Holders of
a majority of the Registrable Shares covered by such registration statement or
the underwriters, if any, shall reasonably and timely object;

               (b) prepare and file with the Commission such amendments and
post-effective amendments to such registration statement and such supplements to
the prospectus used in connection therewith as may be necessary to keep such
registration statement effective (to the extent otherwise required by this
Agreement) and to comply with the provisions of the Securities Act with respect
to the disposition of all securities covered by such registration statement
until such time as all of such securities have been disposed of in accordance
with the intended methods of disposition by the seller or sellers thereof set
forth in such registration statement or the expiration of the Demand Period (in
the case of a Demand Registration), whichever occurs earlier; PROVIDED, HOWEVER,
that the only remedy for any failure to keep the registration statement so
effective shall be as set forth in Section 2.2.2 and PROVIDED, FURTHER, that the
Company will have no obligation to a Selling Holder participating on a
"piggyback" basis in a registration statement that has become effective to keep
such registration statement effective for a period beyond one hundred twenty
(120) days from the effective date of such registration statement;

               (c) cooperate and assist in any filings required to be made with
the National Association of Securities Dealers, Inc. (the "NASD");

               (d) notify each Selling Holder and the managing underwriter, if
any, promptly (and in any event within three (3) business days): (i) when the
prospectus or any prospectus supplement or post-effective amendment has been
filed, and with respect to the registration statement or any post-effective
amendment, when the same has become effective; (ii) of any request by the
Commission or any other federal or state governmental authority for any
amendments or supplements to the registration statement or the prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the registration statement or the
initiation of any proceedings for that purpose; (iv) if, at any time prior to
the closing contemplated by an underwriting agreement entered into in connection
with such registration statement, that the representations and warranties of the
Company contained in such agreement cease to be true and correct; (v) of the
receipt by the Company of any notification with respect to the suspension of the
qualification of the Registrable Shares for sale in any jurisdiction or the
initiation or threatening of any proceeding for such

                                       18

<Page>

purpose; (vi) of the happening of any event which makes any statement made in
the registration statement, the prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue or which requires the
making of any changes in the registration statement, the prospectus or any
document incorporated therein by reference in order to make the statements
therein not misleading; and (vii) of the Company's reasonable determination that
a post-effective amendment to a registration statement would be required;

               (e) make commercially reasonable efforts to prevent the issuance
of any order suspending the effectiveness of the registration statement or of
any order preventing or suspending the use of a prospectus or suspending the
qualification of any of the Registrable Shares included therein for sale in any
jurisdiction (subject to the proviso at the end of the penultimate sentence of
Section 2.5), and, in the event of the issuance of any stop order suspending the
effectiveness of the registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Shares included in such registration statement for sale in any jurisdiction
(subject to the proviso at the end of the penultimate sentence of Section 2.5),
the Company will use its reasonable best efforts to promptly obtain the
withdrawal of any such order;

               (f) furnish to each Selling Holder and the managing underwriters,
if any, without any additional charge, one signed copy of the registration
statement and any post-effective amendment thereto, including financial
statements and schedules, all documents incorporated therein by reference and
all exhibits (including those incorporated by reference);

               (g) as promptly as reasonably practicable, if required, based on
the advice of the Company's counsel, or upon the occurrence of any event
contemplated by Section 2.6(d) hereof, prepare and file a supplement or
post-effective amendment to the registration statement, the related prospectus
or any document incorporated therein by reference or file any other required
document so that, as thereafter delivered to the purchasers of the Registrable
Shares, the prospectus will not contain an untrue statement of a material fact
or omit to state any material fact necessary to make the statements therein not
misleading;

               (h) cause all Registrable Shares covered by the registration
statement to be listed on each securities exchange on which identical securities
issued by the Company are then listed if requested by the Selling Holders
holding a majority in number of the Registrable Shares covered by the
Registration Statement or the managing underwriters, if any;

               (i) provide and cause to be maintained a transfer agent and
registrar for all Registrable Shares covered by such registration statement from
and after a date not later than the effective date of such registration
statement;

               (j) use its reasonable best efforts to provide a CUSIP number for
the Registrable Shares, not later than the effective date of the registration
statement;

               (k) use its reasonable best efforts to (i) obtain opinions of
counsel to the Company (which counsel and opinions (in form, scope and
substance) shall be reasonably satisfactory to the managing underwriters, if
any, and not objected to by the Holders of a majority of the Registrable Shares
being sold), and updates thereof addressed to the Selling

                                       19

<Page>

Holders, covering the matters customarily covered in opinions requested in
underwritten offerings and such other matters as may be reasonably requested by
the underwriters, if any; and (ii) obtain "cold comfort" letters and updates
thereof (which letters and updates (in form, scope and substance) shall be
reasonably satisfactory to the managing underwriters, if any, and counsel to the
Holders of a majority of the Registrable Shares being sold) from the Company's
independent certified public accountants addressed to such Selling Holders (and,
if necessary, any other independent certified public accountants of any
subsidiary of the Company or of any business acquired by the Company for which
financial statements and financial data are, or are required to be, included in
the registration statement), such letters to be in customary form and covering
matters of the type customarily covered in "cold comfort" letters by accountants
in connection with underwritten offerings and such other matters as the
underwriters, if any, or the Holders of a majority of the Registrable Shares
being sold, reasonably request. The above shall be done at each closing under
such underwriting or similar agreement or as and to the extent required
thereunder or, if not an underwritten offering, as otherwise reasonably
requested by the Holders of a majority of the Registrable Shares being sold;

               (l) make available for inspection by a representative of the
Selling Holders and any attorneys or accountants retained by such Holders (and,
to the extent reasonably requested, furnish copies), in connection with the
preparation of a registration statement pursuant to this Agreement, all
financial and other records and pertinent corporate documents and properties of
the Company, and cause the Company's officers, directors and employees to supply
all information reasonably requested by any such representative(s), attorney(s)
or accountant(s) in connection with such registration; PROVIDED, HOWEVER, that
any records, information or documents that are designated by the Company in
writing as confidential shall be kept confidential by such persons unless
disclosure of such records, information or documents is required by court or
administrative order or under applicable law; and PROVIDED, FURTHER, that
appropriate arrangements are made, to the extent required by applicable
antitrust law, to limit access to such information of the Company to
representatives of the Holders who are not officers or employees of the Selling
Holders; and PROVIDED, FURTHER, that, without limiting the foregoing, no such
information shall be used by any such Person in connection with any market
transactions in securities of the Company or its subsidiaries in violation of
law;

               (m) enter into such agreements reasonably requested (including,
as applicable, an underwriting agreement in form, scope and substance as is
customary in underwritten secondary offerings and is reasonably satisfactory to
the Company) and take all such other customary and reasonable actions in
connection therewith (including those requested by the managing underwriters) in
order to expedite or facilitate the disposition of the Registrable Shares, and
in such connection, whether or not an underwriting agreement is entered into and
whether or not the registration is an underwritten registration:

                   (i)   make such representations and warranties to the Holders
         of such Registrable Shares included in the registration statement and
         the underwriters, if any, with respect to the business of the Company
         and the registration statement, prospectus and documents, if any,
         incorporated or deemed to be incorporated by reference therein, in each
         case, in form, substance and scope as are customarily made by

                                       20

<Page>

         issuers to underwriters in underwritten offerings and confirm the same,
         if and when reasonably requested; and

                   (ii)  deliver such documents and certificates as may be
         reasonably requested by the Holders of a majority of the Registrable
         Shares being included in the registration statement and managing
         underwriters, if any, to evidence compliance with clause (a) above and
         with any provisions contained in the underwriting agreement or other
         similar agreement entered into by the Company;

The above shall be done at each closing under such underwriting or similar
agreement or, if not an underwritten offering, to the extent otherwise
reasonably requested by the Holders of a majority of the Registrable Shares
being sold pursuant to the registration statement;

               (n) (i) if so required by the managing underwriter in an
underwritten offering of Registrable Shares covered by a registration statement
filed pursuant to Section 2.2, 2.3 or 2.4 hereof, not publicly or privately
sell, make any short sale of, loan, grant any option, effect any public sale or
distribution of or otherwise dispose of its equity securities or securities

underwritten registration pursuant hereto has become effective, except as part
of such underwritten registration and except pursuant to any exchange offer or
registrations on Form S-4 or S-8 or any successor or similar forms thereto,
except that the Company may make grants of options under its stock option plans
and may issue securities issuable upon the exercise or conversion of outstanding
convertible securities, stock options and other options, warrants and rights of
the Company and (ii) if requested, use reasonable efforts to cause each holder
of ten percent (10%) or more of the securities of the same class as the

hereof, or any securities convertible into or exchangeable or exercisable for
such securities, in each case purchased from the Company at any time after the
date of this Agreement (other than in a registered public offering) to agree not
to effect any public or private sale or distribution or otherwise dispose
(including sales pursuant to Rule 144) of any such securities during the ten
(10) days prior to and the ninety (90) days after any underwritten registration
pursuant hereto has become effective (except as part of such underwritten

registered public offering otherwise agree;

               (o) if requested, furnish each Selling Holder with a copy (or a
reasonable number of copies, as requested) of the registration statement
(together with the Exhibits thereto) and each amendment thereto prior to the

or post-effective amendment promptly following notification of the matters to be
incorporated in such supplement or post-effective amendment;

               (q) upon the occurrence of any event that would cause a shelf
registration statement (i) to contain a material misstatement or omission or
(ii) to be not effective and usable for resale of Registrable Shares during the
Demand Period, the Company shall promptly file an amendment to such shelf
registration statement, in the case of clause (i), correcting any such
misstatement or omission and, in the case of either clause (i) or (ii), use its
commercially reasonable efforts to cause such amendment to be declared effective
and such shelf registration statement to become usable as soon as reasonably
practicable thereafter;

               (r) otherwise use its reasonable best efforts to (i) comply with
all applicable rules and regulations of the Commission and to take all other
steps reasonably necessary to effect the registration of the Registrable Shares

after the end of any twelve-month (12) period if such period is a fiscal year)

Commission for filing the applicable report with the Commission) (y) commencing
at the end of any fiscal quarter in which Registrable Shares are sold to
underwriters in a firm commitment or best efforts underwritten offering and (z)
if not sold to underwriters in such an offering, commencing on the first day of
the first fiscal quarter of the Company after the effective date of a
Registration Statement, which statements shall cover said twelve-month (12)
periods; and

               (s) in connection with any underwritten offering, cooperate with
all marketing efforts reasonably requested by the managing underwriter or
managing underwriters in connection with the sale of the Registrable Shares,
including, without limitation, participation in a reasonable number of road-show
presentations and other marketing activity by Management Stockholders and other
employees of the Company requested by such underwriter or underwriters;
PROVIDED, HOWEVER, that the scheduling of the road-show presentations shall be
set in consultation with the Company and will not require the Company's
involvement at any time or place to which the Company has a reasonable
objection.

         2.7   HOLDBACK AGREEMENTS. Each of the Company and each Holder of
Registrable Shares (whether or not such Registrable Shares are covered by a
Registration Statement filed pursuant to Section 2.2 or 2.3 hereof) agrees, if
requested (pursuant to a timely written notice) by the managing underwriter or
underwriters in an underwritten offering, not to effect any public sale or
distribution of any of the Company's securities, including a sale pursuant to
Rule 144 (except as part of such underwritten offering), during the period
beginning ten (10) days prior to, and ending one hundred and eighty (180) days
after, the closing date of the underwritten offering made pursuant to such
Registration Statement. The foregoing provisions shall not apply to the Company
or any Holder of Registrable Shares if such Person is prevented by applicable
statute or regulation from entering into any such agreement; PROVIDED, HOWEVER,
that any such Person shall undertake not to effect any public sale or
distribution of the class of

                                       22

<Page>

securities covered by such Registration Statement (except as part of such
underwritten offering) during such period unless it has provided sixty (60)
days' prior written notice of such sale or distribution to the managing
underwriter.

         2.8   REGISTRATION EXPENSES. Except as otherwise required by state
securities laws or the rules and regulations promulgated thereunder, all
expenses, disbursements and fees incurred by the Company and the Selling Holders
in connection with carrying out their obligations under this Article II,

underwriters (excluding discounts, commissions or fees of underwriters, selling
brokers, dealer managers or similar securities industry professionals relating
to the distribution of the Registrable Shares) and other Persons retained by the
Company (all such expenses being herein called "REGISTRATION EXPENSES"), will be
borne by the Company regardless of whether a registration statement becomes
effective; PROVIDED, HOWEVER, that the Company will, in any event, pay its
internal expenses (including, without limitation, all salaries and expenses of
its officers and employees performing legal or accounting duties), the expenses
of any annual audit or quarterly review, the fees and expenses of any Person,
including special experts, retained by the Company, the expense of any liability
insurance and the expenses and fees for listing the securities to be registered
on each securities exchange on which similar securities issued by the Company
are then listed or on the Nasdaq Stock Market; and PROVIDED, FURTHER, that each
Selling Holder shall pay (x) all costs and expenses of counsel (other than the
counsel costs referred to in (a) above), accounting or financing professionals
retained by such Selling Holder, (y) all underwriting discounts, commissions,
fees and expenses and all transfer taxes with respect to the Shares sold by such
Selling Holder, and (z) all other expenses incurred by such Selling Holder and
incidental to the sale and delivery of the Shares to be sold by such Holder.

         2.9   CONDITIONS TO HOLDER'S RIGHTS. It shall be a condition of each
Selling Holder's rights hereunder that:

                                       23

<Page>

               2.9.1  COOPERATION. Such Selling Holder shall cooperate with the
Company by supplying information and executing documents relating to such
Selling Holder or the securities of the Company owned by such Selling Holder in
connection with such registration which are customary for offerings of the type
then proposed (including agreeing to sell such Selling Holder's Registrable
Shares on the basis provided in any underwriting arrangements containing
customary terms reasonably satisfactory to such Selling Holder);

               2.9.2  UNDERTAKINGS. Such Selling Holder shall enter into any
undertakings and take such other action relating to the conduct of the proposed
offering which the Company or the underwriters may reasonably request as being
necessary to insure compliance with federal and state securities laws and the
rules or other requirements of the NASD or which the Company or the underwriters
may reasonably request to otherwise effectuate the offering; and

               2.9.3  INDEMNIFICATION. Such Selling Holder shall execute and
deliver an agreement to indemnify to the fullest extent permitted by law and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, any underwriter (as defined in the Securities
Act), and each person, if any, who controls the Company or such underwriter
within the meaning of the Securities Act, against such losses, claims, damages
or liabilities (including reimbursement for legal and other expenses) to which
the Company or any such director, officer, underwriter or controlling person may
become subject under the Securities Act or otherwise, in such manner as is
customary for registrations of the type then proposed, but only with respect to
written information about or pertaining to such Selling Holder furnished by such
Selling Holder for inclusion in the Registration Statement.

         2.10  INDEMNIFICATION.

               2.10.1 INDEMNIFICATION BY THE COMPANY. In the case of any
offering registered pursuant to this Agreement, the Company agrees to indemnify
to the fullest extent permitted by law and hold each Selling Holder, each
affiliate of such Selling Holder and each director, officer, agent,
representative, principal, partner and employee of such Selling Holder and its
affiliates, each Person who controls each Selling Holder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act and the
directors, officers, agents, principals, partners or employees of each such
controlling person harmless against any and all losses, claims, damages,
liabilities, actions (including reasonable and documented costs, including,
without limitation, costs of preparation and reasonable attorneys' fees and
disbursements) and expenses, including reasonable expenses of investigation
(collectively "LOSSES") to which they or any of them may become subject under
the Securities Act or any other statute or common law or otherwise, insofar as
any such Losses shall arise out of, be caused by or shall be based upon (a) any
untrue statement or alleged untrue statement of a material fact contained in the
registration statement relating to the sale of the Registrable Shares covered
thereby, or 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, or (b) any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus (as amended or
supplemented if the Company shall have filed with the Commission any amendment
thereof or supplement thereof), if used prior to the effective date of such
registration

                                       24

<Page>

statement, or contained in the prospectus (as amended or supplemented if the
Company shall have filed with the Commission any amendment thereof or supplement
thereof, including the information deemed part of such registration statement
pursuant to Rule 430A promulgated under the Securities Act), if used within the
period during which the Company shall be required to keep the registration
statement to which such prospectus relates current pursuant to the terms of this
Agreement, or the omission or alleged omission to state therein (if so used) a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading; PROVIDED, HOWEVER,
that the indemnification agreement contained in this Section 2.10.1 shall not
apply to such Losses which shall arise from the sale of Registrable Shares to
any Person if such Losses shall arise out of, shall be caused by or shall be
based upon any such untrue statement or alleged untrue statement, or any such
omission or alleged omission, (x) if such statement or omission shall have been
made in reliance upon and in conformity with information furnished in writing to
the Company by and about such Selling Holder specifically for use in connection
with the preparation of the registration statement or any preliminary prospectus
or prospectus contained in the registration statement or any such amendment
thereof or supplement thereto; (y) if such untrue statement or omission was made
in any preliminary prospectus to the extent that (i) the prospectus corrected
such untrue statement or such omission and (ii) the Selling Holder was legally
required to and failed to send or deliver a copy of the prospectus with or prior
to the delivery of written confirmation of the sale by such Selling Holder of
Registrable Shares to the Person asserting the claim from which such Losses
arise and the Company made the prospectus available to such Selling Holder in
accordance with the terms of the Agreement; or (z) if any such Losses arise out
of, are caused by or are based upon an untrue statement or omission in the
prospectus, to the extent that (i) such untrue statement or omission is
corrected in an amendment or supplement to the prospectus and (ii) having
previously been furnished by or on behalf of the Company with copies of the
prospectus as so amended or supplemented, such Selling Holder was legally
required to and thereafter fails to deliver such prospectus as so amended or
supplemented, prior to or concurrently with the sale of Registrable Shares to
the Person asserting the claim from which such Losses arise. This indemnity
shall be in addition to any other indemnification arrangements to which the
Company may otherwise be a party.

               2.10.2 INDEMNIFICATION BY HOLDERS OF REGISTRABLE SHARES. Each
Selling Holder agrees to indemnify to the fullest extent permitted by law and
hold the Company and each other Selling Holder, and their respective affiliates,
directors, officers, agents, members, principals, partners and employees, each
Person who controls the Company or such other Selling Holder within the meaning
of Section 15 of the Securities Act or Section 20 of the Exchange Act and the
directors, officers, agents or employees of such controlling persons harmless
against any and all Losses arising out of, caused by or based upon any untrue
statement of a material fact contained in any registration statement, prospectus
or form of prospectus, or arising out of, caused by or based upon any omission
of a material fact required to be stated therein or necessary to make the
statements therein (in the case of the preliminary prospectus and the
prospectus, in each case including amendments or supplements), in the light of
the circumstances in which they were made not misleading, to the extent, but
only to the extent, that such untrue statement or omission was contained in any
information regarding such Selling Holder furnished in writing by such Selling
Holder to the Company, expressly for use in such registration statement or
prospectus; PROVIDED, HOWEVER, that the obligation to indemnify will be several
and

                                       25

<Page>

not joint and in no event shall the liability of any Selling Holder hereunder be
greater in amount than the dollar amount of the proceeds (net of the payment of
underwriting discounts and commissions payable by such Selling Holder) received
by any such Selling Holder upon the sale of the Registrable Shares giving rise
to such indemnification obligation. The Company and the Selling Holders shall be
entitled to receive indemnities from underwriters, selling brokers, dealer
managers and similar securities industry professionals participating in the
distribution to the same extent as provided above with respect to information so
furnished in writing by such Persons and regarding such Person expressly for use
in any prospectus or registration statement.

               2.10.3 CONDUCT OF INDEMNIFICATION PROCEEDINGS. Any Person
entitled to indemnity under this Agreement (an "INDEMNIFIED PARTY") shall give
prompt written notice to the party from which such indemnity is sought (the
"INDEMNIFYING PARTY") of any claim or of the commencement of any proceeding with
respect to which such Indemnified Party seeks indemnification or contribution
pursuant hereto; PROVIDED, HOWEVER, that the failure so to notify the
Indemnifying Party shall not relieve the Indemnifying Party from any obligation
or liability except to the extent that the Indemnifying Party has been
prejudiced materially by such failure. The Indemnifying Party shall have the
right exercisable by giving written notice to an Indemnified Party promptly
after the receipt of written notice from such Indemnified Party of such claim or
proceeding to assume, at the Indemnifying Party's expense, the defense of any
such claim or proceeding, with counsel reasonably satisfactory to such
Indemnified Party; PROVIDED, HOWEVER, that under such circumstances an
Indemnified Party shall have the right to employ separate counsel in any such
claim or proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party
unless: (1) the Indemnifying Party agrees to pay such fees and expenses; or (2)
the Indemnifying Party fails promptly to assume the defense of such claim or
proceeding or fails to employ counsel reasonably satisfactory to such
Indemnified Party; or (3) the Indemnified Party shall have been advised by
counsel that (a) there may be one or more material defenses available to such
Indemnified Party that are different from or additional to those available to
the Indemnifying Party or its affiliates or (b) a conflict of interest likely
exists if such counsel represents such Indemnified Party and such Indemnifying
Party or its affiliate, in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof, it being understood, however, that the
Indemnifying Party shall not, in connection with any one such claim or
proceeding, or separate but substantially similar or related claims or
proceedings arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys
(together with appropriate local counsel which such counsel shall be designated
by the Indemnified Party and be reasonably acceptable to the Indemnifying Party)
at any time for such Indemnified Party, or for fees and expenses that are not
reasonable. Whether or not such defense is assumed by the Indemnifying Party,
such Indemnifying Party will not be subject to any liability for any settlement
made without its consent (which consent shall not be unreasonably withheld). The
Indemnifying Party shall not consent to entry of any judgment or settle or
compromise any pending or threatened claim, action or proceeding, unless it
contains as an unconditional term thereof the giving by the claimant or
plaintiff to the Indemnified Party of a release, in form and substance
satisfactory to such Indemnified Party, from all liability in respect

                                       26

<Page>

of such claim or litigation for which such Indemnified Party would be entitled
to indemnification hereunder.

         The Indemnifying Party's liability to any such Indemnified Party
hereunder shall not be extinguished solely because any other Indemnified Party
is not entitled to indemnity hereunder.

               2.10.4 CONTRIBUTION. If the indemnification provided for in this
Section 2.10 is unavailable to an Indemnified Party in respect of any Losses or
is insufficient to hold such Indemnified Party harmless, then, except to the
extent that contribution is not permitted under Section 11(f) of the Securities
Act, each applicable Indemnifying Party shall contribute to the amount paid or
payable by such Indemnified Party as a result of such Losses, in such proportion
as is appropriate to reflect the relative fault of the Indemnifying Party, on
the one hand, and such Indemnified Party, on the other hand, in connection with
the actions, statements or omissions that resulted in such Losses as well as any
other relevant equitable considerations appropriate under the circumstances. The
relative fault of such Indemnifying Party, on the one hand, and such Indemnified
Party, on the other hand, shall be determined by reference to, among other
things, whether any action in question, including any untrue statement of a
material fact or omission to state a material fact, has been taken or made by,
or relates to information supplied by, such Indemnifying Party or Indemnified
Party, and the parties' relative intent, knowledge, access to information
concerning the matter with respect to which the claim was asserted and
opportunity to correct or prevent such action, statement or omission. The amount
paid or payable by a party as a result of any Losses shall be deemed to include
any legal or other fees or expenses reasonably incurred by such party in
connection with any investigation or proceeding.

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 2.10.4 were determined by PRO RATA
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 2.10.4, no Indemnifying Party
that is a Selling Holder shall be required to contribute any amount in excess of
the amount by which the net proceeds received by such Selling Holder from the
sale of Registrable Shares exceeds the amount of any damages that such Selling
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission. 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.

               2.10.5 UNDERWRITING AGREEMENT TO GOVERN. At such time as an
underwriting agreement with respect to a particular underwriting is entered
into, the terms of any such underwriting agreement shall govern with respect to
the matters set forth therein to the extent inconsistent with this Section 2.10;
PROVIDED, HOWEVER, however, that the indemnification provisions of such
underwriting agreement as they relate to Selling Holders are customary for
registrations of the type then proposed and provide for indemnification by such
Selling Holders only with respect to written information regarding such Selling
Holder furnished by such Selling Holders.

                                       27

         2.11  RULE 144. Following the Initial Public Offering, the Company
shall file the reports required to be filed by it under the Securities Act and
the Exchange Act and the rules and regulations adopted by the Commission
thereunder and will take such further action as any Holder of Registrable Shares
may reasonably request, all to the extent required from time to time to enable
such Holder to sell Registrable Shares without registration under the Securities
Act within the limitation of the exemptions provided by Rule 144. Upon the
request of any Holder of Registrable Shares, the Company will deliver to such
Holder a written statement as to whether it has complied with such requirements.

                                  ARTICLE III.

parties fail to comply with any of the obligations herein imposed on them and
that, in the event of any such failure, an aggrieved person will be irreparably
damaged and will not have an adequate remedy of law. Any such person shall,
therefore, be entitled to injunctive relief, including specific performance, to
enforce such obligations, without the posting of any bond and if any action
should be brought in equity to enforce any of the provisions of this Agreement,
none of the parties hereto shall raise the defense that there is an adequate
remedy at law.

         5.4   LEGEND. In addition to any other legend which may be required by
applicable law, each share certificate representing Shares which are subject to
this Agreement shall have endorsed, to the extent appropriate, upon its face the
following words:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED

         ANY EXEMPTION FROM REGISTRATION UNDER SUCH ACT, OR APPLICABLE STATE
         SECURITIES LAW, RELATING TO THE DISPOSITION OF SECURITIES, INCLUDING
         RULE 144, PROVIDED AN OPINION OF COUNSEL IS FURNISHED TO THE COMPANY,
         IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE COMPANY, TO THE
         EFFECT THAT AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT
         AND/OR APPLICABLE STATE SECURITIES LAW IS AVAILABLE.

         IN ADDITION, THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
         TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE
         DISPOSED OF UNLESS SUCH TRANSFER COMPLIES WITH THE PROVISIONS OF A

         COMPANY. NO TRANSFER OF THE SECURITIES WILL BE MADE ON THE BOOKS OF THE
         COMPANY UNLESS ACCOMPANIED BY EVIDENCE OF COMPLIANCE WITH THE TERMS OF
         SUCH STOCKHOLDERS AGREEMENT. THE SECURITIES REPRESENTED BY THIS
         CERTIFICATE ARE ALSO SUBJECT TO OTHER RIGHTS AND OBLIGATIONS AS SET
         FORTH IN THE STOCKHOLDERS AGREEMENT.

have ceased to be effective, the Company will upon request reissue certificates
without the applicable legend or legends.

after the date of the receipt of a written notice from the Company setting forth
such amendment or waiver by any consent authorized by this Section 5.5, whether

amendments, and grant any consents or waivers on behalf of the parties that such
Representative represents. The parties hereto shall be entitled to deal
exclusively with the respective Representatives with respect to matters arising
out of this Agreement, and the parties hereto shall be entitled to deliver any

be transferred by the Company and (b) no rights or obligations of any

         5.9   SEVERABILITY. In case any one or more of the provisions contained
in this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had
never been contained herein; PROVIDED, HOWEVER, that the parties hereto shall
use their reasonable best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
invalid, illegal or unenforceable term, provision, covenant or restriction.

the parties with respect to the subject matter hereof. There are no

expressly set forth or referred to herein. This Agreement supersedes all prior
agreements and understandings between the parties with respect to its subject
matter, including the Original Agreement.

         5.11  GOVERNING LAW. THE RIGHTS AND LIABILITIES OF THE PARTIES SHALL BE
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF DELAWARE, REGARDLESS OF THE CHOICE

commenced (including any proceedings in a bankruptcy court) between the parties
hereto or their representatives concerning any provision of this Agreement or
the rights and duties of any person or entity hereunder, the party or parties
prevailing in such proceeding shall be entitled, in addition to such other

matter of convenience, and in no way define, limit, extend or interpret the

as of the date of this Agreement with respect to the Shares held as of such
date) shall hold any of its Shares in nominee name unless it otherwise provides
the Company and the other Stockholders with its name and address and other
information reasonably requested by the Company in order to establish such
Stockholder's particular status under this Agreement (e.g., Purchaser Holder,
Management Party, etc.).

         5.15  COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

have that any such proceeding in any court in the State of Delaware has been
brought in an inconvenient forum.
