2.Exchange Offer

(a)Unless the Exchange Offer would not be permitted by applicable laws or a

to) (i) prepare and file with the SEC promptly after the date hereof, but in no
event later than the Filing Date, a registration statement (the "Exchange
Registration Statement") on an appropriate form under the Securities Act with
respect to an offer (the "Exchange Offer") to the Holders of Notes to issue and
deliver to such Holders, in exchange for the Notes, a like principal amount of
Exchange Notes, (ii) use its commercially reasonable efforts to cause the
Exchange Registration Statement to be declared effective as promptly as
practicable after the filing thereof, but in no event later than the
Effectiveness Date, (iii) use its commercially reasonable efforts to keep the
Exchange Registration Statement effective until the consummation of the Exchange
Offer in accordance with its terms, and (iv) commence the Exchange Offer and use
its commercially reasonable efforts to issue on or prior to 30 Business Days
after the date on which the Exchange Registration Statement is declared
effective, Exchange Notes in exchange for all Notes tendered prior thereto in
the Exchange Offer. The Exchange Offer shall not be subject to any conditions,
other than that the Exchange Offer does not violate applicable law or any
applicable interpretation of the staff of the SEC.

(b)The Exchange Notes shall be issued under, and entitled to the benefits of,
(i) the Indenture or a trust indenture that is identical to the Indenture (other
than such changes as are necessary to comply with any requirements of the SEC to
effect or maintain the qualifications thereof under the TIA) and (ii) the
Collateral Agreements.

(c)Interest on the Exchange Notes and Private Exchange Notes will accrue from
the last interest payment due date on which interest was paid on the Notes
surrendered in exchange therefor or, if no interest has been paid on the Notes,
from the date of original issue of the Notes. Each Exchange Note and Private
Exchange Note shall bear interest at the rate set forth thereon; provided, that
interest with respect to the period prior to the issuance thereof shall accrue
at the rate or rates borne by the Notes from time to time during such period.

(d)The Company may require each Holder as a condition to participation in the
Exchange Offer to represent (i) that any Exchange Notes received by it will be
acquired in the ordinary course of its business, (ii) that at the time of the
commencement and consummation of the Exchange Offer such Holder has not entered
into any arrangement or understanding with any Person to participate in the
distribution (within the meaning of the Securities Act) of the Exchange Notes in
violation of the provisions of the Securities Act, (iii) that if such Holder is
an "affiliate" of the either of the Company within the meaning of Rule 405 of
the Securities Act, it will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable to it, (iv) if such
Holder is not a broker-dealer, that it is not engaged in, and does not intend to
engage in, the distribution of the Notes and (v) if such Holder is a
Participating Broker-Dealer, that it will deliver a Prospectus in connection
with any resale of the Exchange Notes.

(e)The Company shall (and shall cause each Subsidiary Guarantor to) include
within the Prospectus contained in the Exchange Registration Statement a section
entitled "Plan of Distribution" reasonably acceptable to the Initial Purchasers
which shall contain a summary

4

--------------------------------------------------------------------------------

statement of the positions taken or policies made by the staff of the SEC with
respect to the potential "underwriter" status of any broker-dealer that is the
beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange
Notes received by such broker-dealer in the Exchange Offer for its own account
in exchange for Notes that were acquired by it as a result of market-making or
other trading activity (a "Participating Broker-Dealer"), whether such positions
or policies have been publicly disseminated by the staff of the SEC or such
positions or policies, in the judgment of the Initial Purchasers, represent the
prevailing views of the staff of the SEC. Such "Plan of Distribution" section
shall also allow, to the extent permitted by applicable policies and regulations
of the SEC, the use of the Prospectus by all Persons subject to the prospectus
delivery requirements of the Securities Act, including, to the extent so
permitted, all Participating Broker-Dealers, and include a statement describing
the manner in which Participating Broker-Dealers may resell the Exchange Notes.
The Company shall use its commercially reasonable efforts to keep the Exchange
Registration Statement effective and to amend and supplement the Prospectus
contained therein, in order to permit such Prospectus to be lawfully delivered
by all Persons subject to the prospectus delivery requirements of the Securities
Act for such period of time as such Persons must comply with such requirements
in order to resell the Exchange Notes (the "Applicable Period").

(f)If, upon consummation of the Exchange Offer, any Initial Purchaser holds any
Notes acquired by such Initial Purchaser and having the status of an unsold
allotment in the initial distribution, the Company (upon the written request
from such Initial Purchaser) shall, simultaneously with the delivery of the
Exchange Notes in the Exchange Offer, issue and deliver to such Initial
Purchaser, in exchange (the "Private Exchange") for the Notes held by such
Initial Purchaser, a like principal amount of Senior Secured Notes that are
identical to the Exchange Notes except for the existence of restrictions on
transfer thereof under the Securities Act and securities laws of the several
states of the United States (the "Private Exchange Notes") (and which are issued
pursuant to the same indenture as the Exchange Notes). The Private Exchange
Notes shall bear the same CUSIP number as the Exchange Notes.

(g)In connection with the Exchange Offer, the Company shall (and shall cause
each Subsidiary Guarantor to):

(i)mail to each Holder a copy of the Prospectus forming part of the Exchange
Registration Statement, together with an appropriate letter of transmittal that
is an exhibit to the Exchange Offer Registration Statement, and any related
documents;

(ii)keep the Exchange Offer open for not less than 20 Business Days after the
date notice thereof is mailed to the Holders (or longer if required by
applicable law);

(iii)utilize the services of a depository for the Exchange Offer with an address
in the Borough of Manhattan, the City of New York, which may be the Trustee or
an affiliate thereof;

(iv)permit Holders to withdraw tendered Registrable Notes at any time prior to
the close of business, New York time, on the last Business Day on which the
Exchange Offer shall remain open; and

(v)otherwise comply in all material respects with all applicable laws.

(h)As soon as practicable after the close of the Exchange Offer or the Private
Exchange, as the case may be, the Company shall (and shall cause each Subsidiary
Guarantor to):

(i)accept for exchange all Registrable Notes validly tendered pursuant to the
Exchange Offer or the Private Exchange, as the case may be, and not validly
withdrawn;

(ii)deliver to the Trustee for cancellation all Registrable Notes so accepted
for exchange; and

5

--------------------------------------------------------------------------------

(iii)cause the Trustee to authenticate and deliver promptly to each Holder
tendering such Registrable Notes, Exchange Notes or Private Exchange Notes, as
the case may be, equal in principal amount to the Notes of such Holder so
accepted for exchange.

(i)The Exchange Notes and the Private Exchange Notes may be issued under (i) the
Indenture or (ii) an indenture identical to the Indenture (other than such
changes as are necessary to comply with any requirements of the SEC to effect or
maintain the qualification thereof under the TIA), which in either event will
provide that the Exchange Notes will not be subject to the transfer restrictions
set forth in the Indenture, that the Private Exchange Notes will be subject to
the transfer restrictions set forth in the Indenture, and that the Exchange
Notes, the Private Exchange Notes and the Notes, if any, will be deemed one
class of security (subject to the provisions of the Indenture) and entitled to
participate in all the security granted by the Company pursuant to the
Collateral Agreements and in any Subsidiary Guarantee (as such terms are defined
in the Indenture) on an equal and ratable basis.

(j)If: (i) prior to the consummation of the Exchange Offer, the Holders of a
majority in aggregate principal amount of Registrable Notes determines in its or
their reasonable judgment that (A) the Exchange Notes would not, upon receipt,
be tradeable by the Holders thereof without restriction under the Securities Act
and the Exchange Act and without material restrictions under applicable Blue Sky
or state securities laws, or (B) the interests of the Holders under this
Agreement, taken as a whole, would be materially adversely affected by the
consummation of the Exchange Offer; (ii) applicable interpretations of the staff
of the SEC would not permit the consummation of the Exchange Offer prior to the
Effectiveness Date; (iii) subsequent to the consummation of the Private
Exchange, any Holder of Private Exchange Notes so requests; (iv) the Exchange
Offer is not consummated within 300 days of the Closing Date for any reason; or
(v) in the case of (A) any Holder not permitted by applicable law or SEC policy
to participate in the Exchange Offer, (B) any Holder participating in the
Exchange Offer that receives Exchange Notes that may not be sold without
restriction under state and federal securities laws (other than due solely to
the status of such Holder as an affiliate of the Company within the meaning of
the Securities Act) or (C) any broker-dealer that holds Notes acquired directly
from the Company or any of its affiliates and, in each such case contemplated by
this clause (v), such Holder notifies the Company within six months of
consummation of the Exchange Offer, then the Company shall promptly (and in any
event within five Business Days) deliver to the Holders (or in the case of an
occurrence of any event described in clause (v) of this Section 2(j), to any
such Holder) and the Trustee notice thereof (the "Shelf Notice") and shall as
promptly as possible thereafter file an Initial Shelf Registration pursuant to
Section 3.

3.Shelf Registration

        If a Shelf Notice is delivered pursuant to Section 2(j), then this
Section 3 shall apply to all Registrable Notes. Otherwise, upon consummation of
the Exchange Offer in accordance with Section 2, the provisions of Section 3
shall apply solely with respect to (i) Notes held by any Holder thereof not
permitted to participate in the Exchange Offer, (ii) Notes held by any
broker-dealer that acquired such Notes directly from the Company or any of its
affiliates and (iii) Exchange Notes that are not freely tradeable as
contemplated by Section 2(j)(v) hereof, provided in each case that the relevant
Holder has duly notified the Company within six months of the Exchange Offer as
required by Section 2(j)(v).

(a)Initial Shelf Registration. The Company shall (and shall cause each
Subsidiary Guarantor to), as promptly as practicable, file with the SEC a
Registration Statement for an offering to be made on a continuous basis pursuant
to Rule 415 covering all of the Registrable Notes (the "Initial Shelf
Registration"). If the Company (and any Subsidiary Guarantor) has not yet filed
an Exchange Registration Statement, the Company shall (and shall cause each
Subsidiary

6

--------------------------------------------------------------------------------

Guarantor to) file with the SEC the Initial Shelf Registration on or prior to
the Filing Date and shall use its commercially reasonable efforts to cause such
Initial Shelf Registration to be declared effective under the Securities Act on
or prior to the Effectiveness Date. Otherwise, the Company shall (and shall
cause each Subsidiary Guarantor to) use its commercially reasonable efforts to
file with the SEC the Initial Shelf Registration within 30 days of the delivery
of the Shelf Notice and shall use its commercially reasonable efforts to cause
such Shelf Registration to be declared effective under the Securities Act as
promptly as practicable thereafter (but in no event more than 90 days after
delivery of the Shelf Notice). The Initial Shelf Registration shall be on
Form S-1 or another appropriate form permitting registration of such Registrable
Notes for resale by Holders in the manner or manners reasonably designated by
them (including, without limitation, one or more underwritten offerings). The
Company and Subsidiary Guarantors shall not permit any securities other than the
Registrable Notes to be included in any Shelf Registration. The Company shall
(and shall cause each Subsidiary Guarantor to) use its commercially reasonable
efforts to keep the Initial Shelf Registration continuously effective under the
Securities Act until the date which is two years from the Closing Date (subject
to extension pursuant to the last paragraph of Section 6(w) (the "Effectiveness
Period"), or such shorter period ending when (i) all Registrable Notes covered
by the Initial Shelf Registration have been sold in the manner set forth and as
contemplated in the Initial Shelf Registration (ii) a Subsequent Shelf
Registration covering all of the Registrable Notes covered by and not sold under
the Initial Shelf Registration or an earlier Subsequent Shelf Registration has
been declared effective under the Securities Act or (iii) there cease to be any
outstanding Registrable Notes.

(b)Subsequent Shelf Registrations. If the Initial Shelf Registration or any
Subsequent Shelf Registration (as defined below) ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered thereunder), the Company shall (and
shall cause each Subsidiary Guarantor to) use its commercially reasonable
efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within 30 days of such cessation
of effectiveness amend such Shelf Registration in a manner to obtain the
withdrawal of the order suspending the effectiveness thereof, or file (and cause
each Subsidiary Guarantor to file) an additional "shelf" Registration Statement
pursuant to Rule 415 covering all of the Registrable Notes (a "Subsequent Shelf
Registration"). If a Subsequent Shelf Registration is filed, the Company shall
(and shall cause each Subsidiary Guarantor to) use its commercially reasonable
efforts to cause the Subsequent Shelf Registration to be declared effective as
soon as practicable after such filing and to keep such Subsequent Shelf
Registration continuously effective for a period equal to the number of days in
the Effectiveness Period less the aggregate number of days during which the
Initial Shelf Registration or any Subsequent Shelf Registration was previously
continuously effective. As used herein the term "Shelf Registration" means the
Initial Shelf Registration and any Subsequent Shelf Registrations.

(c)Supplements and Amendments. The Company shall promptly supplement and amend
any Shelf Registration if required by the rules, regulations or instructions
applicable to the registration form used for such Shelf Registration, if
required by the Securities Act, or if reasonably requested in writing by the
Holders of a majority in aggregate principal amount of the Registrable Notes
covered by such Shelf Registration or by any underwriter of such Registrable
Notes.

(d)Provision of Information. No Holder of Registrable Notes shall be entitled to
include any of its Registrable Notes in any Shelf Registration pursuant to this
Agreement unless such Holder furnishes to the Company and the Trustee in
writing, within 20 days after receipt of a written request therefor, such
information as the Company and the Trustee after conferring with

7

--------------------------------------------------------------------------------

counsel with regard to information relating to Holders that would be required by
the SEC to be included in such Shelf Registration or Prospectus included
therein, may reasonably request for inclusion in any Shelf Registration or
Prospectus included therein, and no such Holder shall be entitled to Additional
Interest pursuant to Section 4 hereof unless and until such Holder shall have
provided such information.

4.Additional Interest

(a)The Company and each Subsidiary Guarantor acknowledges and agrees that the
Holders of Registrable Notes will suffer damages if the Company or any
Subsidiary Guarantor fails to fulfill its material obligations under Section 2
or Section 3 hereof and that it would not be feasible to ascertain the extent of
such damages with precision. Accordingly, the Company and the Subsidiary
Guarantors agree to pay additional cash interest on the Notes ("Additional
Interest") under the circumstances and to the extent set forth below (each of
which shall be given independent effect):

(i)if neither the Exchange Registration Statement nor the Initial Shelf
Registration has been filed on or prior to the applicable Filing Date,
Additional Interest shall accrue on the Notes over and above any stated interest
at a rate of 0.25% per annum of the principal amount of such Notes for the first
90 days immediately following the applicable Filing Date, such Additional
Interest rate increasing by an additional 0.25% per annum at the beginning of
each subsequent 90-day period;

(ii)if neither the Exchange Registration Statement nor the Initial Shelf
Registration is declared effective on or prior to the applicable Effectiveness
Date, Additional Interest shall accrue on the Notes over and above any stated
interest at a rate of 0.25% per annum of the principal amount of such Notes for
the first 90 days immediately following the applicable Effectiveness Date, such
Additional Interest rate increasing by an additional 0.25% per annum at the
beginning of each subsequent 90-day period;

(iii)if (A) the Company (and any Subsidiary Guarantor) has not exchanged
Exchange Notes for all Notes validly tendered in accordance with the terms of
the Exchange Offer on or prior to the 30 Business Days after the Effectiveness
Date, (B) the Exchange Registration Statement ceases to be effective at any time
prior to the time that the Exchange Offer is consummated, (C) if applicable, a
Shelf Registration has been declared effective and such Shelf Registration
ceases to be effective at any time prior to the second anniversary of its
effective date (other than such time as all Notes have been disposed of
thereunder) and is not declared effective again within 30 days, or (D) pending
the announcement of a material corporate transaction, event, occurrence or other
item the Company issues a written notice pursuant to Section 6(e)(v) or
(vi) that a Shelf Registration Statement or Exchange Registration Statement is
unusable and the aggregate number of days in any 365-day period for which all
such notices issued or required to be issued, have been, or were required to be,
in effect exceeds 90 days in the aggregate or 30 days consecutively, in the case
of a Shelf Registration statement, or 15 days in the aggregate in the case of an
Exchange Registration Statement, then Additional Interest shall accrue on the
Notes, over and above any stated interest, at a rate of 0.25% per annum of the
principal amount of such Notes commencing on (w) the 31st Business Day after the
Effectiveness Date, in the case of (A) above, or (x) the date the Exchange
Registration Statement ceases to be effective without being declared effective
again within 30 days, in the case of clause (B) above, or (y) the day such Shelf
Registration ceases to be effective in the case of (C) above, or (z) the day the
Exchange Registration Statement or Shelf Registration ceases to be usable in
case of clause (D) above, such Additional Interest rate increasing

8

--------------------------------------------------------------------------------

by an additional 0.25% per annum at the beginning of each such subsequent 90-day
period;

provided, however, that the maximum Additional Interest rate on the Notes may
not exceed at any one time in the aggregate 1.00% per annum; and provided
further, that (1) upon the filing of the Exchange Registration Statement or
Initial Shelf Registration (in the case of (i) above), (2) upon the
effectiveness of the Exchange Registration Statement or Initial Shelf
Registration (in the case of (ii) above), or (3) upon the exchange of Exchange
Notes for all Notes tendered (in the case of (iii)(A) above), or upon the
effectiveness of the Exchange Registration Statement that had ceased to remain
effective (in the case of clause (iii)(B) above), or upon the effectiveness of a
Shelf Registration which had ceased to remain effective (in the case of (iii)(C)
above), Additional Interest on the Notes as a result of such clause (or the
relevant subclause thereof) or upon the usability of such Registration Statement
or Exchange Registration Statement (in the case of clause (iii)(D) above), as
the case may be, shall cease to accrue.

(b)The Company shall notify the Trustee within 3 Business Days after each and
every date on which an event occurs in respect of which Additional Interest is
required to be paid (an "Event Date"). Any amounts of Additional Interest due
pursuant to clause (a)(i), (a)(ii) or (a)(iii) of this Section 4 will be payable
in cash, on the dates and in the manner provided in the Indenture and whether or
not any cash interest would then be payable on such date, commencing with the
first such semi-annual date occurring after any such Additional Interest
commences to accrue. The amount of Additional Interest will be determined by
multiplying the applicable Additional Interest rate by the principal amount of
the Notes, multiplied by a fraction, the numerator of which is the number of
days such Additional Interest rate was applicable during such period (determined
on the basis of a 360-day year comprised of twelve 30-day months and, in the
case of a partial month, the actual number of days elapsed), and the denominator
of which is 360.

5.Hold-Back Agreements

        The Company agrees that it will not effect any public or private sale or
distribution (including a sale pursuant to Regulation D under the Securities
Act) of any securities the same as or similar to those covered by a Registration
Statement filed pursuant to Section 2 or 3 hereof (other than Additional Notes
(as defined in the Indenture) issued under the Indenture), or any securities
convertible into or exchangeable or exercisable for such securities, during the
10 days prior to, and during the 90-day period beginning on, the effective date
of any Registration Statement filed pursuant to Sections 2 and 3 hereof unless
the Holders of a majority in the aggregate principal amount of the Registrable
Notes to be included in such Registration Statement consent, if the managing
underwriter thereof so requests in writing.

6.Registration Procedures

        In connection with the filing of any Registration Statement pursuant to
Sections 2 or 3 hereof, the Company shall (and shall cause each Subsidiary
Guarantor to) effect such registrations to permit the sale of such securities
covered thereby in accordance with the intended method or methods of disposition
thereof, and pursuant thereto and in connection with any Registration Statement
filed by the Company hereunder, the Company shall (and shall cause each
Subsidiary Guarantor to):

(a)Prepare and file with the SEC as soon as practicable after the date hereof
but in any event on or prior to the Filing Date, the Exchange Registration
Statement or if the Exchange Registration Statement is not filed because of the
circumstances contemplated by Section 2(j), a Shelf Registration as prescribed
by Section 3, and use its commercially reasonable efforts to cause each such
Registration Statement to be declared effective and remain effective as

9

--------------------------------------------------------------------------------

provided herein; provided that, if (1) a Shelf Registration is filed pursuant to
Section 3 or (2) a Prospectus contained in an Exchange Registration Statement
filed pursuant to Section 2 is required to be delivered under the Securities Act
by any Participating Broker-Dealer who seeks to sell Exchange Notes during the
Applicable Period relating thereto, before filing any Registration Statement or
Prospectus or any amendments or supplements thereto the Company shall (and shall
cause each Subsidiary Guarantor to), if requested, furnish to and afford the
Holders of the Registrable Notes to be registered pursuant to such Shelf
Registration Statement, each Participating Broker-Dealer, the managing
underwriters, if any, and each of their respective counsel, a reasonable
opportunity to review copies of all such documents (including copies of any
documents to be incorporated by reference therein and all exhibits thereto)
proposed to be filed (in each case at least 5 Business Days prior to such
filing). The Company and each Subsidiary Guarantor shall not file any such
Registration Statement or Prospectus or any amendments or supplements thereto in
respect of which the Holders must provide information for the inclusion therein
without the Holders being afforded an opportunity to review such documentation
if the holders of a majority in aggregate principal amount of the Registrable
Notes covered by such Registration Statement, or any such Participating
Broker-Dealer, as the case may be, the managing underwriters, if any, or any of
their respective counsel shall reasonably object in writing on a timely basis. A
Holder shall be deemed to have reasonably objected to such filing if such
Registration Statement, amendment, Prospectus or supplement, as applicable, as

to state any material fact necessary to make the statements therein not
misleading or fails to comply with the applicable requirements of the Securities
Act.

such purpose, (v) of the happening of any event, the existence of any condition
of any information becoming known that makes any statement made in such
Registration Statement or related Prospectus or any document incorporated or

preliminary prospectus, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements

Guarantors also agree to indemnify underwriters, selling brokers, dealer
managers and similar securities industry professionals participating in the

Losses arising out of or based upon any untrue or alleged untrue statement of a
material fact contained in any Registration Statement, Prospectus or form of
prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, or any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading to the
extent, but only to the extent, that such losses are

18

--------------------------------------------------------------------------------

finally judicially determined by a court of competent jurisdiction in a final,
unappealable order to have resulted solely from an untrue statement or alleged
untrue statement of a material fact or omission or alleged omission of a
material fact contained in or omitted from any information so furnished in
writing by such Holder to the Company and the Subsidiary Guarantors expressly
for use therein. Notwithstanding the foregoing, in no event shall the liability
of any selling Holder be greater in amount than such Holder's Maximum
Contribution Amount (as defined below).

(c)Conduct of Indemnification Proceedings. If any proceeding shall be brought or
asserted against any Person entitled to indemnity hereunder (an "Indemnified
Party"), such Indemnified Party shall promptly notify the party or parties from
which such indemnity is sought (the "Indemnifying Party" or "Indemnifying
Parties", as applicable) in writing; provided, that the failure to so notify the
Indemnifying Parties shall not (i) relieve such Indemnifying Party from any
obligation or liability unless and only to the extent it is materially
prejudiced as a result thereof and (ii) will not, in any event, relieve the
Indemnifying Party from any obligations to any Indemnified Party.

        The Indemnifying Party shall have the right, exercisable by giving
written notice to an Indemnified Party, within 20 Business Days after receipt of
written notice from such Indemnified Party of such proceeding, to assume, at its
expense, the defense of any such proceeding, provided, that an Indemnified Party
shall have the right to employ separate counsel in any such 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 or parties unless: (1) the
Indemnifying Party has agreed to pay such fees and expenses; or (2) the
Indemnifying Party shall have failed promptly to assume the defense of such
proceeding or shall have failed to employ counsel reasonably satisfactory to
such Indemnified Party; or (3) the named parties to any such proceeding
(including any impleaded parties) include both such Indemnified Party and the
Indemnifying Party or any of its affiliates or controlling persons, and such
Indemnified Party shall have been advised by counsel that there may be one or
more defenses available to such Indemnified Party that are in addition to, or in
conflict with, those defenses available to the Indemnifying Party or such
affiliate or controlling person (in which case, if such Indemnified Party
notifies the Indemnifying Parties in writing that it elects to employ separate
counsel at the expense of the Indemnifying Parties, the Indemnifying Parties
shall not have the right to assume the defense and the reasonable fees and
expenses of such counsel shall be at the expense of the Indemnifying Party; it
being understood, however, that, the Indemnifying Party shall not, in connection
with any one such proceeding or separate but substantially similar or related
proceedings in the same jurisdiction, 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) at any
time for such Indemnified Party).

        No Indemnifying Party shall be liable for any settlement of any such
proceeding effected without its written consent, which shall not be unreasonably
withheld, but if settled with its written consent, or if there be a final
judgment for the plaintiff in any such proceeding, each Indemnifying Party
jointly and severally agrees, subject to the exceptions and limitations set
forth above, to indemnify and hold harmless each Indemnified Party from and
against any and all Losses by reason of such settlement or judgment. The
Indemnifying Party shall not consent to the entry of any judgment or enter into
any settlement unless such judgment or settlement (i) includes as an
unconditional term thereof the giving by the claimant or plaintiff to each
Indemnified Party of a release, in form and substance reasonably satisfactory to
the Indemnified Party, from all liability in respect of such proceeding for
which such Indemnified Party would be entitled to indemnification hereunder
(whether or not any Indemnified Party is a party thereto) and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act by or on behalf of any Indemnified Party.

19

--------------------------------------------------------------------------------

(d)Contribution. If the indemnification provided for in this Section 8 is
unavailable to an Indemnified Party or is insufficient to hold such Indemnified
Party harmless for any Losses in respect of which this Section 8 would otherwise
apply by its terms (other than by reason of exceptions provided in this
Section 8), then each applicable Indemnifying Party, in lieu of indemnifying
such Indemnified Party, shall have a joint and several obligation to 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.
The relative fault of such Indemnifying Party, on the one hand, and Indemnified
Party, on the other hand, shall be determined by reference to, among other
things, whether any untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
supplied by such Indemnifying Party or Indemnified Party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent any such statement or omission. The amount paid or payable by an
Indemnified Party as a result of any Losses shall be deemed to include any legal
or other fees or expenses incurred by such party in connection with any
proceeding, to the extent such party would have been indemnified for such fees
or expenses if the indemnification provided for in Section 8(a) or 8(b) was
available to such party.

        The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 8(d) were determined by pro rata
allocation or by other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 8(d), a selling Holder shall not
be required to contribute, in the aggregate, any amount in excess of such
Holder's Maximum Contribution Amount. A selling Holder's "Maximum Contribution
Amount" shall equal the excess of (i) the aggregate proceeds received by such
Holder pursuant to the sale of such Registrable Notes or Exchange Notes over
(ii) the aggregate amount of damages that such 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. The Holders' obligations to contribute pursuant to this
Section 8(d) are several in proportion to the respective principal amount of the
Registrable Securities held by each Holder hereunder and not joint. The
Company's and Subsidiary Guarantors' obligations to contribute pursuant to this
Section 8(d) are joint and several.

        The indemnity and contribution agreements contained in this Section 8
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

9.Rules 144 and 144A

        The Company covenants that it shall (a) file the reports required to be
filed by it (if so required) under the Securities Act and the Exchange Act in a
timely manner and, if at any time the Company is not required to file such
reports, it will, upon the written request of any Holder of Registrable Notes,
make publicly available other information necessary to permit sales pursuant to
Rule 144 and 144A and (b) take such further action as any Holder may reasonably
request in writing, all to the extent required from time to time to enable such
Holder to sell Registrable Notes without registration under the Securities Act
pursuant to the exemptions provided by Rule 144 and Rule 144A. Upon the request
of any Holder, the Company shall deliver to such Holder a written statement as
to whether it has complied with such information and requirements.

20

--------------------------------------------------------------------------------

10.Underwritten Registrations of Registrable Notes

        If any of the Registrable Notes covered by any Shelf Registration is to
be sold in an underwritten offering, the investment banker or investment bankers
and manager or managers that will manage the offering will be selected by the
Holders of a majority in aggregate principal amount of such Registrable Notes
included in such offering; provided, however, that such investment banker or
investment bankers and manager or managers must be reasonably acceptable to the
Company.

        No Holder of Registrable Notes may participate in any underwritten
registration hereunder unless such Holder (a) agrees to sell such Holder's
Registrable Notes on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and
(b) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents required under the terms of such
underwriting arrangements.

11.Miscellaneous

(a)Remedies. In the event of a breach by either the Company or any of the
Subsidiary Guarantors of any of their respective obligations under this
Agreement, each Holder, in addition to being entitled to exercise all rights
provided herein, in the Indenture or, in the case of the Initial Purchasers, in
the Purchase Agreement, or granted by law, including recovery of damages, will
be entitled to specific performance of its rights under this Agreement. The
Company and the Subsidiary Guarantors agree that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by either the
Company or any of the Subsidiary Guarantors of any of the provisions of this
Agreement and hereby further agree that, in the event of any action for specific
performance in respect of such breach, the Company shall (and shall cause each
Subsidiary Guarantor to) waive the defense that a remedy at law would be
adequate.

(b)No Inconsistent Agreements. The Company and each of the Subsidiary Guarantors
have not entered, as of the date hereof, and the Company and each of the
Subsidiary Guarantors shall not enter, after the date of this Agreement, into
any agreement with respect to any of its securities that is inconsistent with
the rights granted to the Holders of Securities in this Agreement or otherwise
conflicts with the provisions hereof. The Company and each of the Subsidiary
Guarantors have not entered and will not enter into any agreement with respect
to any of its securities that will grant to any Person piggy-back rights with
respect to a Registration Statement.

(c)Adjustments Affecting Registrable Notes. The Company shall not, directly or
indirectly, take any action with respect to the Registrable Notes as a class
that would adversely affect the ability of the Holders to include such
Registrable Notes in a registration undertaken pursuant to this Agreement.

(d)Amendments and Waivers. The provisions of this Agreement may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, otherwise than with the prior written
consent of the Holders of not less than a majority in aggregate principal amount
of the then outstanding Registrable Notes in circumstances that would adversely
affect any Holders of Registrable Notes; provided, however, that Section 8 and
this Section 11(d) may not be amended, modified or supplemented without the
prior written consent of each Holder. Notwithstanding the foregoing, a waiver or
consent to depart from the provisions hereof with respect to a matter that
relates exclusively to the rights of Holders of Registrable Notes whose
securities are being tendered pursuant to the Exchange Offer or sold pursuant to
a Notes Registration Statement and that does not directly or indirectly affect,
impair, limit or compromise the rights of other Holders of Registrable Notes may
be given by

21

Notes being tendered or being sold by such Holders pursuant to such Notes
Registration Statement.
