                        (B) (1) Upon the receipt of any Request by the

                                      -5-


            Company will, subject to the other provisions of this Section 2(a),
            cause to be filed with the SEC a Required Registration Statement
            covering the Registrable Securities which the Company has been so
            requested to register in such Request and all other Registrable
            Securities which the Company has been requested to register by the
            MSCP Investor Group, all to the extent necessary to permit the
            disposition of such Registrable Securities so to be registered in
            accordance with the intended methods of distribution thereof
            specified in such Request or further requests.

                        (2) Upon the receipt of any Request after the
            consummation of a Qualified IPO, the Company will, by the tenth day
            thereafter, give written notice of such requested registration to
            all Holders of Registrable Securities, and each such Holder shall be
            entitled to notify the Company within ten days of receipt of notice
            of such Request of such Holder's election to include all or a
            portion of its Registrable Securities in such registration; provided

            who is entitled to sell all of the Registrable Securities owned by
            such Holder at such time pursuant to Rule 144 or Rule 145 of the
            Securities Act shall not be entitled to such notice and shall not be
            entitled to include any Registrable Securities in such registration
            unless on the date of determination the average daily trading volume
            of the Shares during the 30 trading days prior to such date is less
            than the total number of Shares owned by such Holder. Not later than
            the 60th day after the receipt of such a Request by the Company, the
            Company will, subject to the other provisions of this Section 2(a),
            cause to be filed with the SEC a Required Registration Statement
            covering the Registrable Securities which the Company has been so
            requested to register in such Request and all other Registrable
            Securities which the Company has been requested to register by
            Holders thereof other than the Holder(s) who are members of the
            Investor Group initiating such Request, all to the extent necessary
            to permit the disposition of such Registrable Securities so to be
            registered in accordance with the intended methods of distribution
            thereof specified in such Request or further requests.

                        (3) For any Required Registration Statement prepared and
            filed pursuant to Section 2(a)(i), the Company shall use all
            reasonable efforts to have such Required Registration Statement
            declared effective by the SEC as soon as practicable after the
            filing of such Required Registration Statement and to keep such
            Required Registration Statement continuously effective (x) for a
            period of at least 60 days, in the case of a Required Registration
            other than a Shelf Registration (or, in the case of an Underwritten
            Offering, such period as the Underwriters shall reasonably require)
            following the date on which such Required Registration Statement is
            declared effective (or such shorter period which will terminate when
            all of the Registrable Securities covered by such Required
            Registration Statement have been sold pursuant thereto) or (y) until
            all of the Registrable Securities that are the subject of such
            Required Registration Statement have been disposed of pursuant
            thereto, in the case of a Shelf Registration, including, in either
            case, if necessary, by filing with the SEC a post-effective
            amendment or a supplement to the Required Registration Statement or

                                      -6-


            the related Prospectus or any document incorporated therein by
            reference or by filing any other required document or otherwise
            supplementing or amending the Required Registration Statement, if
            required by the rules, regulations or instructions applicable to the
            registration form used by the Company for such Required Registration
            Statement or by the Securities Act, the Exchange Act, any state
            securities or blue sky laws, or any rules and regulations
            thereunder.

                        (C) The Company shall not be required to effect,
            pursuant to this Section 2(a)(i), (w) more than one Required
            Registration within any continuous six month period, (x) any
            Underwritten Offering covering Registrable Securities with gross
            proceeds reasonably expected by the Holders to be less than $25
            million, or (y) more than two (2) Required Registrations requested
            by the MSCP Investor Group; provided, however, that for purposes of
            clause (y), any Required Registration initiated pursuant to a
            Request by the MSCP Investor Group shall, subject to Sections
            2(a)(i)(D) and 2(d) below, be treated as a Required Registration
            requested by the MSCP Investor Group for purposes of this Section
            2(a)(i)(C) only if the MSCP Investor Group sells a majority of the
            Registrable Securities included within the offering related to such
            Required Registration (or, in the case of a Shelf Registration, only
            if the MSCP Investor Group is the beneficial owner of a majority of
            the Registrable Securities registered in such Shelf Registration);
            and provided further, that any Required Registration constituting a
            Shelf Registration initiated pursuant to a Request by the MSCP
            Investor Group shall, subject to Sections 2(a)(i)(D) and 2(d) below,
            be treated as being requested by the MSCP Investor Group for
            purposes of this Section 2(a)(i)(C) only if management of the
            Company is required to travel on a "road show" or the offering
            pursuant to such Required Registration results in any lock-up being
            imposed on the Blackstone Investor Group or the Company. The
            Management Members shall have no right to, and shall not, make a
            Request in respect of a Required Registration at any time. For the
            avoidance of doubt, the Blackstone Investor Group shall not be
            limited as to the number of Required Registrations which it is
            entitled to request under this Section 2(a)(i).

                        (D) A Request may be withdrawn prior to the filing of
            the Required Registration Statement by the Investor Group which made
            such Request and a Required Registration Statement may be withdrawn
            prior to the effectiveness thereof by the Holders of a majority of
            the Registrable Securities included therein, and, in either such
            event, such withdrawal shall not be treated as a Required
            Registration for purposes of clauses (w) or (y) of the immediately
            preceding paragraph.

                        (E) Notwithstanding the foregoing, (1) the Blackstone
            Investor Group shall have the right to suspend any Shelf
            Registration requested by the MSCP Investor Group for a period not
            to exceed 90 days upon the Blackstone Investor Group submitting to
            the Company its own Request for a Required Registration (a
            "Blackstone Blackout Period") (it being understood that the MSCP
            Investor Group shall have the right to participate in such Required
            Registration pursuant to Section 2(a)(i)(B)); and (2) the Company
            may delay the filing of a

                                      -7-


            Required Registration Statement (irrespective of the Investor Group
            submitting the Request with respect thereto) for a period not to
            exceed 90 days if the board of directors of the Company determines
            in good faith that the Company or its subsidiaries are engaged in,
            or plan to engage in, any financing, acquisition or other material
            transaction which would be adversely affected by the filing of a
            registration statement (a "Company Blackout Period"; together with
            the Blackstone Blackout Period, a "Blackout Period"); provided that
            neither the MSCP Investor Group nor the Blackstone Investor Group
            shall be subject to more than one Blackout Period in any six month
            period.

                        (F) The registration rights granted pursuant to the
            provisions of this Section 2(a)(i) shall be in addition to the
            registration rights granted pursuant to the other provisions of this
            Section 2.

                  (ii) Priority in Required Registrations. If a Required
      Registration pursuant to this Section 2(a) involves an Underwritten
      Offering, and the sole Underwriter or the lead managing Underwriter, as
      the case may be, of such Underwritten Offering shall advise the Company in
      writing (with a copy to each Holder requesting registration) that, in its
      opinion, the amount of Registrable Securities requested to be included in
      such Required Registration exceeds the amount which can be sold in such
      offering without adversely affecting the distribution of the Registrable
      Securities being offered, the Company will include in such Required
      Registration only the amount of Registrable Securities that the Company is
      so advised can be sold in such offering without so adversely affecting
      such distribution; provided, however, that the Company shall be required
      to include in such Required Registration first, all Registrable Securities
      requested to be included in the Required Registration by the Investor
      Members and, if any, the Management Members and, to the extent not all
      such Registrable Securities can be included in such Required Registration,
      the number of Registrable Securities to be included shall be allocated pro
      rata among such Members on the basis of the number of Registrable
      Securities requested to be included in such Required Registration by each
      such Member or on such other basis as shall be agreed among such Investor
      Members and the Management Representative (if the Management Members have
      requested Registrable Securities to be included in such Required
      Registration); second, all Registrable Securities requested to be included
      in such Required Registration by the other Holders and, to the extent not
      all such Registrable Securities can be included in such Required
      Registration, the number of Registrable Securities to be included shall be
      allocated pro rata among such other Holders on the basis of the number of
      Registrable Securities requested to be included in such Required
      Registration by each such Holder and third, all other securities
      requested, in accordance with any registration rights which are granted in
      compliance with Section 6(a), to be included in such Required Registration
      which are of the same class as the Registrable Securities otherwise to be
      included in such Required Registration and, to the extent not all such
      securities can be included in such Required Registration, the number of
      securities to be included shall be allocated pro rata among the holders
      thereof requesting inclusion in such Required Registration on the basis of
      the number of securities requested to be included by all such holders.

                                      -8-


            (b) Incidental Registration.

                  (i) Right to Include Registrable Securities. If at any time in
      connection with or after the consummation of an IPO, the Company proposes
      to register any Shares under the Securities Act (other than (A) any
      registration of public sales or distributions solely by and for the
      account of the Company of securities issued (x) pursuant to any employee
      benefit or similar plan or any dividend reinvestment plan or (y) in any
      acquisition by the Company or financing thereof, or (B) pursuant to
      Section 2(a) hereof (it being understood that such Section 2(a) provides
      for incidental registration rights with respect to registrations conducted
      thereunder) in connection with a primary offering for cash for the account
      of the Company or a secondary offering, the Company will, each time it
      intends to effect such a registration, subject to the following
      qualifications, give written notice (the "Company Notice") (1) in
      connection with or at any time after an IPO, to the Blackstone Investor
      Group, (2) in connection with or at any time after a Qualified IPO, to
      each of the Investor Groups, and (3) at any time after a Qualified IPO, to
      all Holders of Registrable Securities (including the Investor Groups), at
      least ten but no more than 45 days prior to the expected initial filing of
      a Registration Statement with the SEC pertaining thereto, informing such
      Holders entitled to receive the Company Notice (the "Eligible Holders") of
      its intent to file such Registration Statement, the expected filing date,
      and of the Eligible Holders' rights to request the registration of the
      Registrable Securities held by the Eligible Holders under this Section
      2(b); provided that any Holder owning less than 1% of the outstanding
      Shares and who is entitled to sell all of the Registrable Securities owned
      by such Holder at such time pursuant to Rule 144 or Rule 145 of the
      Securities Act shall not be entitled to such notice and shall not be an
      "Eligible Holder" with respect to such registration unless on the date of
      determination the average daily trading volume of the Shares during the 30
      trading days prior to such date is less than the total number of Shares
      owned by such Holder. Upon the written request of any such Eligible Holder
      made within ten days after any such Company Notice is given (which request
      shall specify the Registrable Securities intended to be disposed of by
      such Eligible Holder and, unless the applicable registration is intended
      to effect a primary offering of Shares for cash for the account of the
      Company, the intended method of distribution thereof), the Company will
      use all reasonable efforts to effect the registration under the Securities
      Act of all Registrable Securities which the Company has been so requested
      to register by such Eligible Holders to the extent required to permit the
      disposition (in accordance with the intended methods of distribution
      thereof or, in the case of a registration which is intended to effect a
      primary offering for cash for the account of the Company, in accordance
      with the Company's intended method of distribution) of the Registrable
      Securities so requested to be registered, including, if necessary, by
      filing with the SEC a post-effective amendment or a supplement to the
      Incidental Registration Statement or the related Prospectus or any
      document incorporated therein by reference or by filing any other required
      document or otherwise supplementing or amending the Incidental
      Registration Statement, if required by the rules, regulations or
      instructions applicable to the registration form used by the Company for
      such Incidental Registration Statement or by the Securities Act, any state
      securities or blue sky laws, or any rules and regulations thereunder;
      provided, however, that in connection with a Qualified IPO, the Company
      shall have no obligation to, and shall not, include or cause to be
      included in the Incidental Registration Statement any Registrable
      Securities requested

                                      -9-


      to be included by the MSCP Investor Group if the Blackstone Investor Group
      does not also register Registrable Securities held by it in such
      Incidental Registration Statement; and provided further that if, at any
      time after giving written notice of its intention to register any
      securities and prior to the effective date of the Incidental Registration
      Statement filed in connection with such registration, the Company shall
      determine for any reason not to register or to delay registration of such
      securities, the Company may, at its election, give written notice of such
      determination to each Eligible Holder and, thereupon, (A) in the case of a
      determination not to register, the Company 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
      incurred in connection therewith), and (B) in the case of a determination
      to delay such registration, the Company shall be permitted to delay
      registration of any Registrable Securities requested to be included in
      such Incidental Registration Statement for the same period as the delay in
      registering such other securities.

           The registration rights granted pursuant to the provisions of this
      Section 2(b)(i) shall be in addition to the registration rights granted
      pursuant to the other provisions of this Section 2.

                  (ii) Priority in Incidental Registrations. If a registration
      pursuant to this Section 2(b) involves an Underwritten Offering of the
      securities so being registered, whether or not for sale for the account of
      the Company, and the sole Underwriter or the lead managing Underwriter, as
      the case may be, of such Underwritten Offering shall advise the Company in
      writing (with a copy to each Holder of Registrable Securities requesting
      registration) that, in its opinion, the amount of securities (including
      Registrable Securities) requested to be included in such registration
      exceeds the amount which can be sold in (or during the time of) such
      offering without adversely affecting the distribution of the securities
      being offered, then the Company will be required to include in such
      registration, first, all the securities entitled to be sold pursuant to
      such Registration Statement without reference to the incidental
      registration rights of any holder (including Holders); second all
      Registrable Securities requested to be included in the Underwritten
      Offering by the Investor Members and Management Members and, to the extent
      not all such Registrable Securities can be included in such Underwritten
      Offering, the number of Registrable Securities to be included shall be
      allocated pro rata among such Members on the basis of the number of
      Registrable Securities requested to be included in the Underwritten
      Offering by all the Investor Members and Management Members or on such
      other basis as shall be agreed among such Investor Members and the
      Management Representative (if the Management Members have requested
      Registrable Securities to be included in such Required Registration)
      (provided that, the provisions under this clause "second" shall have
      priority over the foregoing clause "first" if Blackstone gives notice to
      the Company that Blackstone is electing to have the applicable
      Underwritten Offering to constitute a Required Registration); third, all
      Registrable Securities requested to be included in such Underwritten
      Offering by the other Holders and, to the extent not all such Registrable
      Securities can be included in such Underwritten Offering, the number of
      Registrable Securities to be included shall be allocated pro rata among
      such other Holders on the basis of the number of Registrable Securities
      requested to be included in such Underwritten Offering by all such Holders
      and fourth, all other

                                      -10-


      securities requested, in accordance with any registration rights which are
      granted in compliance with Section 6(a), to be included in such
      Underwritten Offering which are of the same class as the Registrable
      Securities otherwise to be included in such Required Registration and, to
      the extent not all such securities can be included in such Underwritten
      Offering, the number of securities to be included shall be allocated pro
      rata among the holders thereof requesting inclusion in such Underwritten
      Offering on the basis of the number of securities requested to be included
      by all such holders; provided, however, that in the event the Company will
      not, by virtue of this paragraph, include in any such registration all of
      the Registrable Securities of any Holder requested to be included in such
      registration, such Holder may, upon written notice to the Company given
      within three days of the time such Holder first is notified of such
      matter, reduce the amount of Registrable Securities it desires to have
      included in such registration, whereupon only the Registrable Securities,
      if any, it desires to have included will be so included and the Holders
      not so reducing shall be entitled to a corresponding increase in the
      amount of Registrable Securities to be included in such registration.

            (c) Expenses. The Company agrees to (i) pay all Registration
Expenses in connection with each of the registrations requested pursuant to
Section 2(a) and (ii) pay all Registration Expenses in connection with each
registration as to which Holders request inclusion of Registrable Securities
pursuant to Section 2(b). All Selling Expenses relating to securities registered
on behalf of Holders shall be borne by the Holders of securities included in
such registration pro rata on the basis of the number of securities so
registered.

            (d) Effective Registration Statement; Suspension. Subject to Section
2(a)(i)(D), a Registration Statement pursuant to Section 2(a) will not be deemed
to have become effective (and the related registration will not be deemed to
have been effected) unless it has been declared effective by the SEC or, in the
case of a Registration Statement filed pursuant to Rule 415 (or any similar rule
then in force) in connection with a Shelf Registration, unless Registrable
Securities have been disposed of pursuant thereto, prior to a request by the
Holders of a majority of the Registrable Securities included in such
registration that such Registration Statement be withdrawn; provided, however,
that if, after it has been declared effective, the offering of any Registrable
Securities pursuant to such Registration Statement is interfered with by any
stop order, injunction or other order or requirement of the SEC or any other
governmental agency or court, such Registration Statement will be deemed not to
have become effective and the related registration will not be deemed to have
been effected.

            (e) Selection of Underwriters. At any time or from time to time, the
holder (including the Company, if applicable) of the greatest number of
Registrable Securities covered by a Registration Statement may elect to have
such Registrable Securities sold in an Underwritten Offering and may select the
investment banker or investment bankers and manager or managers that will serve
as lead and co-managing Underwriters with respect to the offering of such
Registrable Securities, subject to the consent of the Company, which shall not
be unreasonably withheld. No Holder may participate in any Underwritten Offering
hereunder unless such Holder (i) agrees to sell such Holder's securities on the
basis provided in any underwriting arrangements approved by the Persons entitled
hereunder to approve such arrangements and (ii) completes and executes all
questionnaires, powers of attorney, custody

                                      -11-


agreements, indemnities, underwriting agreements and other documents required
under the terms of such Underwritten Offering.

                        Section 3. Restrictions on Public Sale.

            (a) If requested by the sole Underwriter or lead managing
Underwriter(s) in an Underwritten Offering, the Company agrees not to effect any
public sale or distribution (other than, in the case of the Company, public
sales or distributions solely by and for the account of the Company of
securities issued pursuant to any employee benefit or similar plan or any
dividend reinvestment plan) of any Shares (or equity or equity-linked
securities) during the period commencing on the date the Company receives a
Request from any Holder and continuing until one hundred eighty (180) days after
the effective date of any IPO, Qualified IPO or other Underwritten Offering (or
for such shorter period as the sole or lead managing Underwriter shall request)
unless earlier terminated by the sole Underwriter or lead managing
Underwriter(s) in such Underwritten Offering.

            (b) If requested by the sole Underwriter or lead managing
Underwriter(s) in an Underwritten Offering, the Holders shall not sell or
otherwise transfer or dispose of any Shares (or equity or equity-linked
securities) of the Company held by the Holders (other than those included in the
registration) during the fourteen (14) day period prior to and the one hundred
eighty (180) day period following the effective date (including such effective
date), of an IPO, Qualified IPO or any other offering, or in the case of a Shelf
Registration pursuant to Rule 415 of the Securities Act (or any similar rule
then in force), the 180 day period following the date of any underwritten
take-down, or in either case such shorter period as the sole Underwriter or lead
managing Underwriter(s) may request, provided that the obligations described in
this Section 3(b) shall not apply to a registration relating solely to the sale
of securities to employees of the Company pursuant to a stock option, stock
purchase or similar plan or Rule 145 (or any similar rule then in force) or
similar transaction. The Company may impose stop-transfer instructions with
respect to the Shares (or equity or equity-linked securities) subject to the
foregoing restriction until the end of the applicable period pursuant to the
first sentence of this Section 3(b). Notwithstanding the foregoing, if any
Holder (other than a Management Member who is not a Senior Management Member) is
released from the Underwriters' restriction on the sale or transfer of Shares
(or equity or equity-linked securities) of the Company held by such Holder, all
other Holders subject to such restriction shall also be released to the same
extent (based on the percentage of all Shares of such Holder subject to such
Underwriters' restriction that were released from such restriction). Any
agreement entered into after the date of this Agreement pursuant to which the
Company issues or agrees to issue any privately placed Shares or other
securities shall contain a provision under which holders of such securities
agree not to effect any sale or distribution of any such securities during the
period referred to in the first sentence of this Section 3(b), including any
sale pursuant to Rule 144 under the Securities Act (or any similar rule then in
force) (except as part of such registration, if permitted).

                        Section 4. Registration Procedures.

            In connection with the obligations of the Company pursuant to
Section 2, the Company shall use all reasonable efforts to effect the
registration of the Registrable Securities

                                      -12-


under the Securities Act to permit the sale of such Registrable Securities by
the Holders in accordance with their intended method or methods of distribution,
and the Company shall:

            (a) (i) prepare and file a Registration Statement with the SEC which
(x) shall be on Form S-1 (if in connection with an IPO) and otherwise on Form
S-3 (or any successor to such form), if available, (y) shall be available for
the sale or exchange of the Registrable Securities in accordance with the
intended method or methods of distribution by the selling Holders thereof, and
(z) shall comply as to form with the requirements of the applicable form and
include all financial statements required by the SEC to be filed therewith and
all other information reasonably requested by the lead managing Underwriter or
sole Underwriter, if applicable, to be included therein, (ii) use all reasonable
efforts to cause such Registration Statement to become effective and remain
effective in accordance with Section 2, (iii) use all reasonable efforts to not
take any action that would cause a Registration Statement to contain a material
misstatement or omission or to be not effective and usable for resale of
Registrable Securities during the period that such Registration Statement is
required to be effective and usable, and (iv) cause each Registration Statement
and the related Prospectus and any amendment or supplement thereto, as of the
effective date of such Registration Statement, amendment or supplement (x) to
comply in all material respects with any requirements of the Securities Act and
the rules and regulations of the SEC and (y) not to contain any 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;

            (b) subject to paragraph (j) of this Section 4, prepare and file
with the SEC such amendments and post-effective amendments to each such
Registration Statement, as may be necessary to keep such Registration Statement
effective for the applicable period; cause each such Prospectus to be
supplemented by any required prospectus supplement, and as so supplemented to be
filed pursuant to Rule 424 under the Securities Act (or any similar rule then in
force); and comply with the provisions of the Securities Act with respect to the
disposition of all securities covered by each Registration Statement during the
applicable period in accordance with the intended method or methods of
distribution by the selling Holders thereof, as set forth in such registration
statement;

            (c) furnish to each Holder of Registrable Securities and to each
Underwriter of an Underwritten Offering of Registrable Securities, if any,
without charge, as many copies of each Prospectus, including each preliminary
Prospectus, and any amendment or supplement thereto and such other documents as
such Holder or Underwriter may reasonably request in order to facilitate the
public sale or other disposition of the Registrable Securities; the Company
hereby consents to the use of the Prospectus, including each preliminary
Prospectus, by each Holder of Registrable Securities and each Underwriter of an
Underwritten Offering of Registrable Securities, if any, in connection with the
offering and sale of the Registrable Securities covered by the Prospectus or the
preliminary Prospectus;

            (d) (i) use all reasonable efforts to register or qualify the
Registrable Securities, no later than the time the applicable Registration
Statement is declared effective by the SEC, under all applicable state
securities or "blue sky" laws of such jurisdictions as each Underwriter, if any,
or any Holder of Registrable Securities covered by a Registration Statement,
shall reasonably request; (ii) use all reasonable efforts to keep each such
registration or qualification effective during the period such Registration
Statement is required to be kept effective; and (iii)

                                      -13-


do any and all other acts and things which may be reasonably necessary or
advisable to enable each such Underwriter, if any, and Holder to consummate the
disposition in each such jurisdiction of such Registrable Securities owned by
such Holder; provided, however, that the Company shall not be obligated to
qualify as a foreign corporation or as a dealer in securities in any
jurisdiction in which it is not so qualified or to consent to be subject to
general service of process (other than service of process in connection with
such registration or qualification or any sale of Registrable Securities in
connection therewith) in any such jurisdiction;

            (e) notify each Holder of Registrable Securities promptly, and, if
requested by such Holder, confirm such advice in writing, (i) when a
Registration Statement has become effective and when any post-effective
amendments and supplements thereto become effective, (ii) of the issuance by the
SEC or any state securities authority of any stop order, injunction or other
order or requirement suspending the effectiveness of a Registration Statement or
the initiation of any proceedings for that purpose, (iii) if, between the
effective date of a Registration Statement and the closing of any sale of
securities covered thereby pursuant to any agreement to which the Company is a
party, the representations and warranties of the Company contained in such
agreement cease to be true and correct in all material respects or if the
Company receives any notification with respect to the suspension of the
qualification of the Registrable Securities for sale in any jurisdiction or the
initiation of any proceeding for such purpose, and (iv) of the happening of any
event during the period a Registration Statement is effective as a result of
which such Registration Statement or the related Prospectus contains any untrue
statement of a material fact or omits to state any material fact required to be
stated therein or necessary to make the statements therein not misleading;

            (f) furnish counsel for each such Underwriter, if any, and for the
Holders of Registrable Securities copies of any request by the SEC or any state
securities authority for amendments or supplements to a Registration Statement
and Prospectus or for additional information;

            (g) use all reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement at the earliest
possible time;

            (h) upon request, furnish to the sole Underwriter or lead managing
Underwriter of an Underwritten Offering of Registrable Securities, if any,
without charge, at least one signed copy of each Registration Statement and any
post-effective amendment thereto, including financial statements and schedules,
all documents incorporated therein by reference and all exhibits; and furnish to
each Holder of Registrable Securities, without charge, at least one conformed
copy of each Registration Statement and any post-effective amendment thereto
(without documents incorporated therein by reference or exhibits thereto, unless
requested);

            (i) cooperate with the selling Holders of Registrable Securities and
the sole Underwriter or lead managing Underwriter of an Underwritten Offering of
Registrable Securities, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legends; and enable such Registrable Securities to be in
such denominations (consistent with the provisions of the governing documents
thereof) and registered in such names as the selling Holders or the sole
Underwriter or lead managing Underwriter of an Underwritten Offering of
Registrable

                                      -14-


Securities, if any, may reasonably request at least five days prior to any sale
of Registrable Securities;

            (j) upon the occurrence of any event contemplated by paragraph
(e)(iv) of this Section, use all reasonable efforts to prepare a supplement or
post-effective amendment to a Registration Statement or 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
Securities, such Prospectus will not contain any 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, in the light of the circumstances under which
they were made, not misleading;

            (k) enter into customary agreements (including, in the case of an
Underwritten Offering, underwriting agreements in customary form, and including
provisions with respect to indemnification and contribution in customary form
and consistent with the provisions relating to indemnification and contribution
contained herein) and take all other customary and appropriate actions in order
to expedite or facilitate the disposition of such Registrable Securities and in
connection therewith:

                  (1) make such representations and warranties to the Holders of
            such Registrable Securities and the Underwriters, if any, in form,
            substance and scope as are customarily made by issuers to
            underwriters in similar underwritten offerings;

                  (2) obtain opinions of counsel to the Company and updates
            thereof (which counsel and opinions (in form, scope and substance)
            shall be reasonably satisfactory to the lead managing Underwriter,
            if any, and the Holders of a majority of the Registrable Securities
            being sold by all Holders in such offering) addressed to each
            selling Holder and the Underwriters, if any, covering the matters
            customarily covered in opinions requested in sales of securities or
            underwritten offerings and such other matters as may be reasonably
            requested by such Holders and Underwriters;

                  (3) obtain "cold comfort" letters and updates thereof from the
            Company's independent certified public accountants addressed to the
            selling Holders of Registrable Securities, if permissible, and the
            Underwriters, if any, which letters shall be customary in form and
            shall cover matters of the type customarily covered in "cold
            comfort" letters to underwriters in connection with primary
            underwritten offerings;

                  (4) to the extent requested and customary for the relevant
            transaction, enter into a securities sales agreement with the
            Holders providing for, among other things, the appointment of such
            representative as agent for the selling Holders for the purpose of
            soliciting purchases of Registrable Securities, which agreement
            shall be customary in form, substance and scope and shall contain
            customary representations, warranties and covenants; and

                                      -15-


                  (5) deliver such customary documents and certificates as may
            be reasonably requested by the Majority Holders selling Registrable
            Securities in such offering or by the managing Underwriters, if any.

The above shall be done (i) at the effectiveness of such Registration Statement
(and each post-effective amendment thereto) in connection with any registration,
and (ii) at each closing under any underwriting or similar agreement as and to
the extent required thereunder;

            (l) make available for inspection by representatives of the Holders
of the Registrable Securities and any Underwriters participating in any
disposition pursuant to a Registration Statement and any counsel or accountant
retained by such Holders or Underwriters, all relevant financial and other
records, pertinent corporate documents and properties of the Company and cause
the respective officers, directors and employees of the Company to supply all
information reasonably requested by any such representative, Underwriter,
counsel or accountant in connection with a Registration Statement;

            (m) (i) within a reasonable time prior to the filing of any
Registration Statement, any Prospectus, any amendment to a Registration
Statement or amendment or supplement to a Prospectus, provide copies of such
document to the Holders of Registrable Securities and to counsel to such Holders
and to the Underwriter or Underwriters of an Underwritten Offering of
Registrable Securities, if any; fairly consider such reasonable changes in any
such document prior to or after the filing thereof as the counsel to the Holders
or the Underwriter or the Underwriters may request and not file any such
document in a form to which Holders of a majority of the Registrable Securities
being sold by all Holders in such offering or any Underwriter shall reasonably
object; and make such of the representatives of the Company as shall be
reasonably requested by the Holders of Registrable Securities being registered
or any Underwriter available for discussion of such document;

                (ii) within a reasonable time prior to the filing of any

      prior to or after the filing thereof as counsel for such Holders or such
      Underwriter shall request; and make such of the representatives of the
      Company as shall be reasonably requested by such counsel available for
      discussion of such document;

            (n) cause all Registrable Securities to be qualified for inclusion
in or listed on The New York Stock Exchange, the NASDAQ National Market or any
other securities exchange or quotation system on which securities of the same
class issued by the Company are then so qualified or listed if so requested by
the Holders of a majority of the Registrable Securities being sold by all
Holders in such offering, or if so requested by the Underwriter or Underwriters
of an Underwritten Offering of Registrable Securities, if any;

            (o) otherwise use all reasonable efforts to comply with all
applicable rules and regulations of the SEC, including making available to its
security holders an earnings statement covering at least 12 months which shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder (or any similar provision then in force);

                                      -16-


            (p) cooperate and assist in any filings required to be made with the
NASD and in the performance of any due diligence investigation by any
Underwriter in an Underwritten Offering; and

            (q) use all reasonable efforts to facilitate the distribution and
sale of any Registrable Securities to be offered pursuant to this Agreement,
including without limitation by making road show presentations, holding meetings
with potential investors and taking such other actions as shall be requested by
the Holders of a majority of the Registrable Securities being sold by all
Holders in such offering or the lead managing Underwriter of an Underwritten
Offering; provided that the Company shall not be required to make road show
presentations in connection with any Underwritten Offering of Registrable
Securities that would not reasonably be expected to have gross proceeds of at
least $50 million.

            Each selling Holder of Registrable Securities as to which any
registration is being effected pursuant to this Agreement agrees, as a condition
to the registration obligations with respect to such Holder provided herein, to
furnish to the Company such information regarding such Holder required to be
included in the Registration Statement, the ownership of Registrable Securities
by such Holder and the proposed distribution by such Holder of such Registrable
Securities as the Company may from time to time reasonably request in writing.

            Each Holder agrees that, upon receipt of any notice from the Company
of the happening of any event of the kind described in paragraph (e)(iv) of this
Section, such Holder will forthwith discontinue disposition of Registrable
Securities pursuant to the affected Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus, contemplated by
paragraph (j) of this Section, and, if so directed by the Company, such Holder
will deliver to the Company (at the expense of the Company), all copies in its
possession, other than permanent file copies then in such Holder's possession,
of the Prospectus covering such Registrable Securities which was current at the
time of receipt of such notice.

                        Section 5. Indemnification; Contribution.

            (a) Indemnification by the Company. The Company agrees to indemnify
and hold harmless each Person who participates in the sale of Registrable
Securities hereunder as an underwriter (any such Person being an "Underwriter"),
each Investor Group, Holder and their respective partners, directors, officers
and employees and each Person, if any, who controls any Investor Group, Holder
or Underwriter within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act as follows:

            (i)   against any and all losses, liabilities, claims, damages,
      judgments and reasonable expenses whatsoever, as incurred, arising out of
      any untrue statement or alleged untrue statement of a material fact
      contained in any Registration Statement pursuant to which Registrable
      Securities were registered under the Securities Act, including all
      documents incorporated therein by reference, or the omission or alleged
      omission therefrom of a material fact required to be stated therein or
      necessary to make the statements therein not misleading, or arising out of
      any untrue statement or alleged untrue statement of a material fact
      contained in any Prospectus, including all documents incorporated therein
      by reference, or the omission or alleged omission therefrom of a

                                      -17-


      material fact necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading;

            (ii)  against any and all losses, liabilities, claims, damages,
      judgments and reasonable expenses whatsoever, as incurred, to the extent
      of the aggregate amount paid in settlement of any litigation,
      investigation or proceeding by any governmental agency or body, commenced
      or threatened, or of any other claim whatsoever based upon any such untrue
      statement or omission, or any such alleged untrue statement or omission,
      if such settlement is effected with the written consent of the Company;
      and

            (iii) against any and all reasonable expense whatsoever (including
      fees and disbursements of counsel), as incurred in investigating,
      preparing or defending against any litigation, investigation or proceeding
      by any governmental agency or body, commenced or threatened, in each case
      whether or not such Person is a party, or any claim whatsoever based upon
      any such untrue statement or omission, or any such alleged untrue
      statement or omission, to the extent that any such expense is not paid
      under sub-paragraph (i) or (ii) above;

provided, however, that this indemnity agreement does not apply to any Investor
Group, Holder or Underwriter with respect to any loss, liability, claim, damage,
judgment or expense to the extent arising out of any untrue statement or alleged
untrue statement of a material fact contained in any Prospectus, or the omission
or alleged omission therefrom of a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in any such case made in reliance upon and in conformity
with written information furnished to the Company by such Investor Group, Holder
or Underwriter expressly for use in a Registration Statement (or any amendment
thereto) or any Prospectus (or any amendment or supplement thereto); provided,
further, that the Company shall not be liable to any Holder with respect to any
preliminary prospectus to the extent that any such loss, liability, claim,
damage, cost or expense results from the fact that such Holder sold Registrable
Securities to a Person to whom there was not sent or given, at or prior to the
written confirmation of such sale, a copy of the final prospectus if the Company
has previously and timely furnished copies thereof to such Holder and if such
final prospectus would have corrected such untrue statement or omission. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of any Holder Indemnified Party and shall survive the
transfer of such securities by any Holder.

            (b) Indemnification by Holders. Each selling Holder severally but
not jointly agrees to indemnify and hold harmless the Company, each Underwriter
and the other selling Holders and Investor Groups, and each of their respective
partners, managers, officers and employees (including each officer of the
Company who signed the Registration Statement), and each Person, if any, who
controls the Company, any Underwriter or any other selling Holder or Investor
Group within the meaning of Section 15 of the Securities Act, against any and
all losses, liabilities, claims, damages, judgments and expenses described in
the indemnity contained in paragraph (a) of this Section (provided that any
settlement of the type described therein is effected with the written consent of
such selling Holder), as incurred, but only with respect to untrue statements or
alleged untrue statements of a material fact contained in any Registration
Statement or Prospectus or omissions, or alleged omissions therefrom of a
material fact

                                      -18-


necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, in any such case made in reliance
upon and in conformity with written information furnished to the Company by such
selling Holder expressly for use in such Registration Statement (or any
amendment thereto) or such Prospectus (or any amendment or supplement thereto).

            (c) Conduct of Indemnification Proceedings. Each indemnified party
or parties shall give reasonably prompt notice to each indemnifying party or
parties of any action or proceeding commenced against it in respect of which
indemnity may be sought hereunder, but failure so to notify an indemnifying
party or parties shall not relieve it or them from any liability which it or
they may have under this indemnity agreement, except to the extent that the
indemnifying party is materially prejudiced by such failure to give notice. If
the indemnifying party or parties so elects within a reasonable time after
receipt of such notice, the indemnifying party or parties may assume the defense
of such action or proceeding at such indemnifying party's or parties' expense
with counsel chosen by the indemnifying party or parties and approved by the
indemnified party defendant in such action or proceeding, which approval shall
not be unreasonably withheld; provided, however, that, if such indemnified party
or parties determine in good faith that a conflict of interest exists and that
therefore it is advisable for such indemnified party or parties to be
represented by separate counsel or that, upon advice of counsel, there may be
legal defenses available to it or them which are different from or in addition
to those available to the indemnifying party, then the indemnifying party or
parties shall not be entitled to assume such defense and the indemnified party
or parties shall be entitled to separate counsel (limited in each jurisdiction
to one counsel for all Underwriters and another counsel for all other
indemnified parties under this Agreement) at the indemnifying party's or
parties' expense. If an indemnifying party or parties is or are not so entitled
to assume the defense of such action or does or do not assume such defense,
after having received the notice referred to in the first sentence of this
paragraph, the indemnifying party or parties will pay the reasonable fees and
expenses of counsel for the indemnified party or parties (limited in each
jurisdiction to one counsel for all Underwriters and another counsel for all
other indemnified parties under this Agreement). No indemnifying party or
parties will be liable for any settlement effected without the written consent
of such indemnifying party or parties, which consent shall not be unreasonably
withheld. If an indemnifying party is entitled to assume, and assumes, the
defense of such action or proceeding in accordance with this paragraph, such
indemnifying party or parties shall not be liable for any fees and expenses of
counsel for the indemnified parties incurred thereafter in connection with such
action or proceeding.

            (d) Contribution. (i) In order to provide for just and equitable
      contribution in circumstances in which the indemnity agreement provided
      for in this Section is for any reason held to be unenforceable by the
      indemnified parties although applicable in accordance with its terms in
      respect of any losses, liabilities, claims, damages, judgments and
      expenses suffered by an indemnified party referred to herein, each
      applicable 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 losses, liabilities, claims, damages, judgments
      and expenses in such proportion as is appropriate to reflect the relative
      fault of the Company on the one hand and of the liable selling Holders
      (including, in each case, that of their respective officers, directors,
      employees and agents) on the other in connection with the statements or
      omissions which resulted in

                                      -19-


      such losses, liabilities, claims, damages, judgments or expenses, as well
      as any other relevant equitable considerations. The relative fault of the
      Company on the one hand and of the liable selling Holders (including, in
      each case, that of their respective officers, managers, employees and
      agents) on the other shall be determined by reference to, among other
      things, whether the untrue or alleged untrue statement of a material fact
      or the omission or alleged omission to state a material fact relates to
      information supplied by the Company, on the one hand, or by or on behalf
      of the selling Holders, on the other, and the parties' relative intent,
      knowledge, access to information and opportunity to correct or prevent
      such statement or omission. The amount paid or payable by a party as a
      result of the losses, liabilities, claims, damages, judgments and expenses
      referred to above shall be deemed to include, subject to the limitations
      set forth in paragraph (c) of this Section, any legal or other fees or
      expenses reasonably incurred by such party in connection with
      investigating or defending any action or claim.

                  (ii) The Company and each Holder of Registrable Securities
      agree that it would not be just and equitable if contribution pursuant to
      this paragraph (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 sub-paragraph (i) above. Notwithstanding the
      provisions of this paragraph (d), in the case of distributions to the
      public, an indemnifying Holder shall not be required to contribute any
      amount in excess of the amount by which (A) the total price at which the
      Registrable Securities sold by such indemnifying Holder and its affiliated
      indemnifying Holders and distributed to the public were offered to the
      public exceeds (B) the amount of any damages which such indemnifying
      Holder has otherwise been required to pay by reason of such untrue or
      alleged untrue statement or omission or alleged 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.

                  (iii) For purposes of this Section, each Person, if any, who
      controls a Holder, Investor Group or an Underwriter within the meaning of
      Section 15 of the Securities Act (and their respective partners,
      directors, officers and employees) shall have the same rights to
      contribution as such Holder, Investor Group or Underwriter; and each
      director of the Company, each officer of the Company who signed the
      Registration Statement, and each Person, if any, who controls the Company
      within the meaning of Section 15 of the Securities Act, shall have the
      same rights to contribution as the Company.

                        Section 6. Miscellaneous.

            (a) No Inconsistent Agreements. The Company will not on or after the
date of this Agreement enter into any agreement which conflicts with the
provisions of this Agreement or which grants registration or similar rights
without the prior written consent of the Blackstone Investor Group, the MSCP
Investor Group and the Management Representative, nor has the Company entered
into any such agreement. The rights granted to the Holders hereunder do not in
any way conflict with and are not inconsistent with the rights granted to the
holders of the Company's other issued and outstanding securities under any such
agreements.

                                      -20-


            (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented unless the Company has obtained (i) the prior written consent of
the Holders of a majority of the Registrable Securities, and (ii) if any such
amendment, modification or supplement would adversely affect the rights,
privileges or interests of the Blackstone Investor Group, the MSCP Investor
Group or the Management Members hereunder, the prior written consent of the
Blackstone Investor Group, the MSCP Investor Group or the Management
Representative, respectively.

            (c) Investor Action. Any action which requires the approval of an
Investor Group shall be effective if approved by the Holders beneficially
holding a majority of the Registrable Securities held by all Holders of such
Investor Group.

            (d) Notices. Any notice, demand, request, waiver, or other
communication under this Agreement shall be personally served in writing, shall
be deemed to have been given on the date of service, and shall be addressed as
follows:

            (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of each
of the parties, including, without the need for an express assignment,
subsequent Holders. If any successor, assignee or transferee of any Holder shall
acquire Registrable Securities in any manner, whether by operation of law or
otherwise, such Registrable Securities shall be held subject to all of the terms
of this Agreement, and by taking and holding such Registrable Securities such
Person shall be conclusively deemed to have agreed to be bound by and to perform
all of the terms and provisions of this Agreement. For purposes of this
Agreement, "successor" for any entity other than a natural person shall mean a
successor to such entity as a result of such entity's merger, consolidation,
liquidation, dissolution, sale of substantially all of its assets, or similar
transaction.

            (f) Recapitalizations, Exchanges, etc., Affecting Registrable
Securities. The provisions of this Agreement shall apply, to the full extent set
forth herein with respect to the Registrable Securities, to any and all
securities or capital stock of the Company or any successor or assign of the
Company (whether by merger, consolidation, sale of assets or otherwise) which
may be issued in respect of, in exchange for, or in substitution of such
Registrable Securities, by reason of any dividend, split, issuance, reverse
split, combination, recapitalization, reclassification, merger, consolidation or
