                  (a) Right to Shelf Registration. Commencing one (1) year from
the date hereof, and within 45 days after receipt of written notice from the
Carlyle Group, the Company shall prepare and file with the SEC a registration
statement for an offering to be made on a delayed or continuous basis pursuant
to Rule 415 of the Securities Act (a "Shelf Registration") registering the
resale from time to time by the Carlyle Group and the Holders of all of the

obligated to effect a Shelf Registration pursuant to this Section 2(a) on more
than one occasion in any 12-month period. The Registration Statement for any
Shelf Registration shall be on Form S-3 or another appropriate form permitting
registration of such Registrable Securities for resale by each Holder in the

effective under the Act as

                                        3

<PAGE>

promptly as is practicable and to keep the Shelf Registration continuously
effective under the Securities Act until the earlier of (i) the expiration of
the Effectiveness Period or (ii) the consummation of the disposition by the
Holders of all the Registrable Securities covered by such Registration
Statement. If the Shelf Registration ceases to be effective for any reason at
any time prior to the end of the Effectiveness Period (other than because all
Registrable Securities shall have been sold or shall have ceased to be
Registrable Securities), the Company shall use its best efforts to obtain the
prompt withdrawal of any order suspending the effectiveness thereof, and in any
event shall within thirty (30) days of such cessation of effectiveness amend the
Shelf Registration in a manner reasonable expected to obtain the withdrawal of
the order suspending the effectiveness thereof, or file an additional Shelf
Registration covering all of the Registrable Securities then outstanding (a
"Subsequent Shelf Registration"). If a Subsequent Shelf Registration is filed,
the Company shall use all reasonable efforts to cause the Subsequent Shelf
Registration to become effective as promptly as is practicable after such filing
and to keep such registration statement continuously effective until the end of
the Effectiveness Period.

                       ARTICLE 3. PIGGYBACK REGISTRATION

         (a) Inclusion in Piggyback Registration. If the Company at any time,
proposes to register any of its securities under the Securities Act (other than
pursuant to a Special Registration), whether or not for sale for its own
account, (a "Company Registration"), it shall each such time, prior to such
filing, give prompt written notice to all Holders of Registrable Securities of
its intention to do so and, upon the written request of any Holder of
Registrable Securities given to the Company within twenty (20) days after the
Company has provided such notice (which request shall state the intended method
of disposition of such Registrable Securities), the Company shall use reasonable
efforts to cause all Registrable Securities that the Company has been requested
by the Holders thereof to register to be so registered under the Securities Act
to the extent necessary to permit their disposition in accordance with the
intended methods of distribution specified in the request of such Holder or
Holders and in accordance with Section 3(c). The notice provided by the Company
to Holders shall specify the minimum and maximum proposed offering price and the
name of the proposed underwriter in connection with the offering, the timing of
the proposed offering and other relevant information, as applicable.

         (b) Terms of Underwriting. In connection with any offering under this
Article 3 involving an underwritten offering, the Company shall not be required
to include any Registrable Securities in such offering unless the Holder thereof
accepts the terms and enters into an underwriting agreement, if any, of the
underwriting as agreed upon between the Company and the underwriters selected by
it provided that such terms must be reasonably satisfactory in substance and
form to the Holder and consistent with this Agreement, and then only in such
quantity as will not, in the opinion of the managing underwriter, jeopardize the
success of the offering by the Company.

         (c) Allocation. If any Company Registration involves an underwritten
offering and the managing underwriter of such offering shall advise the Company
that, in its view, the number of securities requested to be included in such
registration exceeds the largest number that can be sold in an orderly manner in
such offering within a price range acceptable to the Company, the Company shall
include Registrable Securities in such registration in the amount as

                                        4

<PAGE>

is determined in good faith by the managing underwriters in the case of a
underwritten public offering; provided, however, that such calculation shall not
treat Registrable Securities in any manner differently than any other
registrable securities of the Company, absent agreement to the contrary

         If any Holder does not agree to the terms of any such underwriting,
such person shall be excluded therefrom by written notice from the Company or
the underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration. If
shares are so withdrawn from the registration or if the number of shares of
Registrable Securities to be included in such registration was previously
reduced as a result of marketing factors, the Company shall then offer to all
persons who have retained the right to include securities in the registration
the right to include additional securities in the registration in an aggregate
amount equal to the number of shares so withdrawn, with such shares to be
allocated among the persons requesting additional inclusion in accordance with
Section 3(c).

         For purposes of this Article 3, in any circumstance in which all of the
Registrable Securities requested to be included in a registration on behalf of
the Holders cannot be so included as a result of limitations of the aggregate
number of shares of Registrable Securities that may be so included, the number
of shares of Registrable Securities that may be so included shall be allocated
among the Holders requesting inclusion of shares such that the selling Holders
of the Registrable Securities shall have their shares included pro rata on the
basis of the aggregate number of shares of Registrable Securities that all
Holders had requested to be included in the registration; provided, however,
that such allocation shall not operate to reduce the aggregate number of
Registrable Securities to be included in such registration. If any Holder does
not request inclusion of the maximum number of shares of Registrable Securities
allocated to such person pursuant to the above-described procedure, the
remaining portion of such person's allocation shall be reallocated among those
requesting Holders whose allocations did not satisfy their requests pro rata on
the basis of the number of shares of Registrable Securities held by such Holders
that such Holders had requested to be included in the registration, and this
procedure shall be repeated until all of the shares of Registrable Securities
which may be included in the registration on behalf of the Holders have been so
allocated. Notwithstanding the foregoing provisions, the Company may withdraw
any Registration Statement referred to in this Article 3 without thereby
incurring any liability to the Holders (but the Company shall nevertheless pay
the Registration Expenses in connection therewith). If any Holder disapproves of
the terms of any such underwriting, it may elect to withdraw therefrom by
written notice to the Company and the underwriter. Any Registrable Securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration but the reallocation provisions of this Section 3(c) shall continue
to apply to such Registrable Securities.

                       ARTICLE 4. ALLOCATION OF EXPENSES

The Company will pay all Registration Expenses of all registrations under this
Agreement.

                     ARTICLE 5. OBLIGATIONS OF THE COMPANY

                                        5

thereof, comply as to form in all material respects with the applicable
accounting requirements of the Securities Act, and such letter shall
additionally cover such other financial matters (including information as to the
period ending no more than five




                                        6

(5) business days prior to the date of such letter) with respect to such
registration as such underwriters reasonably may request;

               (f) immediately notify each Holder of Registrable Securities and
each underwriter under such registration statement, at any time when a
Prospectus relating thereto is required to be delivered under the Securities
Act, of the happening of any event of which the Company has knowledge as a
result of which the Prospectus contained in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing, and promptly
prepare and furnish to such Holder a reasonable number of copies of a Prospectus
supplemented or amended so that, as thereafter delivered to the purchasers of
such Registrable Securities, such Prospectus shall not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing;

               (g) comply with all applicable rules and regulations under the
Securities Act and Exchange Act;

               (h) promptly notify each Holder of Registrable Securities covered

Prospectus used in connection therewith shall be filed, (ii) of any request by
the Commission to amend such Registration Statement or to amend or supplement
such Prospectus or for additional information, (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of such Registration
Statement or of any order preventing or suspending the use of any preliminary
prospectus or the initiation or threatening of any proceedings for any of such
purposes, (iv) of the suspension of the qualification of such securities for
offering or sale in any jurisdiction, or of the institution of any proceedings
for any of such purposes and (v) if at any time when a Prospectus is to be
required by the Securities Act to be delivered in connection with the sale of
the Registrable Securities, the representations and warranties of the Company
contained in any agreement (including the underwriting agreement contemplated in
Section 6(b) below), to the knowledge of the Company, cease to be true and
correct in any material respect;

               (i) cooperate with the Holders and the managing underwriter, if
any, to facilitate the timely preparation and delivery of certificates
representing Registrable Securities to be sold, which certificates shall not
bear any restrictive legends whatsoever and shall be in a form eligible for

obtain the consent or approval of, each governmental agency or authority,

sellers

                                        7

<PAGE>

to offer, or to consummate the disposition of, the Registrable Securities
subject to such Registration Statement, except as may be required solely as a
consequence of the nature of such seller's business, in which case the Company

Statement and the granting of such approvals;

refers to any seller of any securities covered thereby by name, or otherwise
identifies such seller as the holder of any securities of the Company, without
the consent of such seller, such consent not to be unreasonably withheld, except
that no such consent shall be required for any disclosure that is required by
law.

         In connection with each registration hereunder, the Holders of
Registrable Securities will furnish to the Company in writing such information
required by the Company with respect to themselves and the proposed distribution
by them as shall be reasonably necessary in order to assure compliance with

provide to the Company such information as the Company may reasonably request at
the time to enable the Company to comply with applicable laws or regulations or

would violate any law or any contractual arrangement.

Articles 2 and 3, to any registration that is an underwritten offering.

               (a) Underwritten Offerings Exclusive. Whenever a request for
Registration is for an underwritten offering, only securities that are to be
distributed by the underwriters may be included in the Registration.

               (b) Underwriting Agreement. If requested by the underwriters for
any underwritten offering by Holders pursuant to a request for Registration, the
Company shall enter into an underwriting agreement with such underwriters for
such offering, such agreement to be reasonably satisfactory in substance and
form to the Company and Holders of a majority of the Registrable Securities to
be covered by such registration and to the underwriters and to contain such
representations and warranties by the Company and such other terms and
provisions as are customarily contained in agreements of this type.

               (c) Selection of Underwriters. The Company shall have the right
to select any underwriters to administer any underwritten offerings hereunder,
subject to the consent of the


                                        8

<PAGE>

Holders of a majority of the Registrable Securities to be registered pursuant to
such offering, which shall not be unreasonably withheld.

In connection with the preparation and filing of each Registration Statement
registering Registrable Securities under the Securities Act, the Company shall
give the Holders of Registrable Securities to be so registered and their
underwriters, if any, and their respective counsel and accountants, such access
to all pertinent financial, corporate, and other documents and properties of the
Company and its Subsidiaries, and such opportunities to discuss the business of
the Company with its officers, directors, employees and the independent public
accountants who have issued audit reports on its financial statements as shall
be necessary, in the opinion of such Holders' and such underwriters' respective
counsel, to conduct a reasonable investigation within the meaning of the
Securities Act.

                         ARTICLE 8. OTHER REGISTRATIONS

If and whenever the Company is required to use its best efforts to effect the
registration under the Securities Act of any Registrable Securities pursuant to
Articles 2 or 3, and if such registration shall not have been withdrawn or
abandoned, the Company shall not be obligated to and shall not file any
Registration Statement with respect to any of its securities (including
Registrable Securities) under the Securities Act (other than a Special
Registration), whether of its own accord or at the request or demand of any
holder or holders of such securities, until a period of 90 days shall have
elapsed from the effective date of such previous registration, provided that the
Company shall not be excused from filing a Registration Statement by virtue of
this Article 8 more than once in a 360 day period.

                   ARTICLE 9. CERTAIN OBLIGATIONS OF HOLDERS

               (a) The Company may require each Holder of any Registrable
Securities as to which any registration is being effected to furnish to the
Company such information regarding such Holder and the intended method of
disposition of such securities as the Company may from time to time reasonably
request and as shall be required to effect the registration of such Holder's
Registrable Securities. Each such Holder agrees to furnish promptly to the
Company all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

               (b) Each Holder of Registrable Securities covered by a
Registration Statement agrees that, upon receipt of any notice from the Company
pursuant to Section 5(h), such Holder will promptly discontinue the disposition
of Registrable Securities pursuant to such Registration Statement until such
Holder shall have received, in the case of clause (i) of Section 5(h), notice
from the Company that such Registration Statement has been amended, as
contemplated by Section 5(h), and, in the case of clause (ii) of Section 5(h),
copies of the supplemented or amended Prospectus contemplated by Section 5(h).
If so directed by the Company, each Holder will deliver to the Company all
copies, other than permanent file copies, in such Holder's possession of the
Prospectus covering such Registrable Securities at the time of receipt of such
notice. In the event that the Company shall give any such notice, the period
mentioned in

                                        9

<PAGE>

Section 5(b) shall be extended by the number of days during the period from and
including the date of the giving of such notice to and including the date when
each seller of any Registrable Securities covered by such Registration Statement
shall have received copies of the supplemented or amended Prospectus covering
such Registrable Securities contemplated by Section 5(h).

                  ARTICLE 10. INDEMNIFICATION AND CONTRIBUTION

               (a) In the event of any registration of any of the Registrable
Securities under the Securities Act pursuant to this Agreement, the Company will
indemnify and hold harmless the Holder of such securities, its directors,
officers, and employees, each other Person who participates as an underwriter,
broker or dealer (each a "Participating Person") in the offering or sale of such
securities, and each other person, if any, who controls such Holder, or such
Participating Person (each a "Controlling Person") within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages, or
liabilities, joint or several, to which such Holder or any such director,
officer, employee, Participating Person, or Controlling Person may become
subject under the Securities Act, the Exchange Act, state securities or blue sky
laws, or otherwise, insofar as such losses, claims, damages, or liabilities (or
actions or proceedings in respect thereof), including any of the foregoing
incurred in settlement of any litigation commenced or threatened, arise out of
or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, any Prospectus contained
in the Registration Statement, or any amendment or supplement to such
Registration Statement, or arise out of or are based upon the omission or
alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and the Company shall
reimburse such Holder and each such director, officer, employee, Participating
Person, and Controlling Person for any reasonable legal or any other reasonable
expenses, in connection with investigating or defending any such loss, claim,
damage, liability, action or proceeding as such expenses are incurred, whether
or not resulting in any liability; provided, however, that the Company will not
be liable in any such case to the extent that any such loss, claim, damage,
liability or expense arises out of or is based upon any untrue statement or
omission made in such Registration Statement, preliminary prospectus,
Prospectus, or any such amendment or supplement, in reliance upon and in
conformity with information furnished to the Company, in writing, by or on
behalf of such Holder, Participating Person or Controlling Person specifically
for use in the preparation thereof. The indemnity agreement contained in this
Article 10(a) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability or action if such settlement is effected without the
consent of the Company.

               (b) In the event of any registration of any of the Registrable
Securities under the Securities Act pursuant to this Agreement, each Holder of
such Registrable Securities, severally and not jointly, will indemnify and hold
harmless the Company, each of its directors and officers and each underwriter
(if any) and each person, if any, who controls the Company or any such
underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages, or liabilities, joint or several, to which
the Company, such directors and officers, underwriters, or controlling Persons
may become subject under the Securities Act, Exchange Act, state securities or
blue sky laws, or otherwise, insofar as such losses, claims, damages, or
liabilities (or actions or proceedings in respect thereof) arise out of or are
based

                                       10

<PAGE>

upon any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement or Prospectus contained in the
Registration Statement, or any amendment or supplement to the Registration
Statement, or arise out of or are based upon any omission or alleged omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, if the statement or omission was made in
reliance upon and in conformity with information relating to such Holder
furnished in writing to the Company by or on behalf of such Holder for use in
connection with the preparation of such Registration Statement, preliminary
prospectus, Prospectus, amendment, or supplement; provided, however, that the
liability of each such Holder hereunder shall be in proportion to and limited to
the gross amount received by such Holder from the sale of Registrable Securities
sold in connection with such registration.

               (c) Each party entitled to indemnification under this Article 10
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld); and, provided, further, that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Article 10, except to the extent that the Indemnifying
Party is adversely affected by such failure. The Indemnified Party may
participate in such defense at such party's expense; provided, however, that the
Indemnifying Party shall pay such expense if representation of such Indemnified
Party by the counsel retained by the Indemnifying Party would be inappropriate
due to actual or potential differing interests or conflicts between the
Indemnified Party and any other party represented by such counsel in such
proceeding. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement that does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect of such claim or
litigation, and no Indemnified Party shall consent to entry of any judgment or
settle such claim or litigation without the prior written consent of the
Indemnifying Party, which consent shall not be unreasonably withheld.

               (d) If for any reason the foregoing indemnity is unavailable, or
is insufficient to hold harmless an Indemnified Party, other than by reason of
the exceptions provided in this Article 10, then the Indemnifying Party shall,
in lieu of indemnifying such Indemnified Party, contribute to the amount paid or
payable by the Indemnifying Party as a result of such losses, claims, damages
liabilities or expenses in such proportion as is appropriate to reflect the
relative fault of the Indemnifying Party on the one hand and the Indemnified
Party on the other in connection with the statements or omissions which resulted
in such losses, claims, damages, or liabilities, as well as any other relevant
equitable considerations. The relative fault 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 or the Holders of Registrable
Securities covered by the Registration Statement in question and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

       ARTICLE 11. INDEMNIFICATION WITH RESPECT TO UNDERWRITTEN OFFERING

In the event that Registrable Securities are sold pursuant to a Registration
Statement in an underwritten offering, the Company agrees to enter into an
underwriting agreement containing customary representations and warranties with
respect to the business and operations of an issuer of the securities being
registered and customary covenants and agreements to be performed by such
issuer, including without limitation customary provisions with respect to
indemnification by the Company of the underwriters of such offering.

           ARTICLE 12. REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934

With a view to making available to the Holders the benefits of Rule 144
promulgated under the Securities Act and any other rule or regulation of the
Commission that may at any time permit a Holder to sell Registrable Securities
of the Company to the public without Registration, the Company agrees to use its
reasonable efforts to:

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

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

               (c) furnish to any Holder, so long as such Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144 under
the Securities Act, any other such applicable reporting requirements under the
Securities Act and all applicable reporting requirements under the Exchange Act,
(ii) a copy of the most recent annual or quarterly report of the Company and
such other reports and documents so filed by the Company, and (iii) such other
information as may be reasonably requested in availing any Holder of any rule or
regulation of the Commission which permits the selling of any such securities
without Registration or pursuant to such form.

                ARTICLE 13. SUCCESSORS, ASSIGNS AND TRANSFEREES

This Agreement shall be binding upon and shall inure to the benefit of each
party hereto, and their respective successors, assigns and transferees. The
Carlyle Group or any other Holder under this Agreement may assign its rights
under this Agreement only to (i) an Affiliate, (ii) other successors, assigns
and transferees of Carlyle L.L.C., Carlyle, C/S, or Carlyle U.S., or (iii) any
Holder of not less than the lesser of ten percent (10%) of the Warrant Shares
and the Dividend Shares originally held by the Carlyle Group or all the
remaining shares of Registrable Securities held by the assignor (or such lesser
amount of total Registrable Securities held by the assignor) (subject to
adjustment for stock splits, stock dividends and the like); provided, however,
that the Company is given written notice from the Carlyle Group or any such
Holder at the time of such transfer stating the name and address of the
transferee or assign and identifying the securities with respect to which the
rights hereunder are being transferred. As a condition to the effectiveness of
any transfer permitted hereunder (i) the transferee or assign shall agree, in
writing, to be bound by the provisions of this Agreement and (ii) the Company
shall be given written notice at the time of or within a reasonable time after
said transfer or assignment, stating the name and address of said transferee or
assign and identifying the securities with respect to

                                       12

<PAGE>

which such registration rights are being assigned. Provided that the Carlyle
Group or any Holder and any transferee or assignee has complied with the
foregoing conditions, this Agreement shall survive any transfer of Registrable
Securities to and shall inure to the benefit of an Affiliate or such other
successors, assigns and transferees of the Carlyle Group or any such Holder.

                           ARTICLE 14. MISCELLANEOUS

               (a) No Inconsistent Agreements. The Company will not hereafter
enter into any agreement with respect to its securities which is inconsistent
with or violates the rights granted to the Holders in this Agreement.

               (b) Severability. If any term, provision, covenant or restriction
of this Agreement is held by a court of competent jurisdiction to be invalid,
void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants, and restrictions without including any
of such which may be hereafter declared invalid, void or unenforceable.

               (c) Termination. This Agreement shall terminate upon the earlier
to occur of (i) the Registrable Securities held by the Carlyle Group cease to be
Registrable Securities or (ii) the expiration of the Effectiveness Period.
