to exchange all the Registrable Securities for Exchange Securities and (ii) have

(v)   that any Holder will be entitled to withdraw its election, not later than
      the close of business on the last Exchange Date, by sending to the
      institution and at the address (located in the Borough of Manhattan, The
      City of New York) specified in the notice, a telegram, telex, facsimile
      transmission or letter setting forth the name of such Holder, the
      principal amount of Registrable Securities delivered for

                                       5



      exchange and a statement that such Holder is withdrawing its election to
      have such Securities exchanged.

      As a condition to participating in the Exchange Offer, a Holder will be
required to represent to the Company and the Guarantors that (i) any Exchange
Securities to be received by it will be acquired in the ordinary course of its
business, (ii) at the time of the commencement of the Exchange Offer it has no
arrangement or understanding with any Person to participate in the distribution
(within the meaning of the Securities Act) of the Exchange Securities in
violation of the provisions of the Securities Act, (iii) it is not an
"affiliate" (within the meaning of Rule 405 under the Securities Act) of the
Company or any Guarantor and (iv) if such Holder is a broker-dealer that will
receive Exchange Securities for its own account in exchange for Registrable
Securities that were acquired as a result of market-making or other trading
activities, then such Holder will deliver a Prospectus in connection with any
resale of such Exchange Securities.

      As soon as practicable after the last Exchange Date, the Company and the
Guarantors shall:

(i)   accept for exchange Registrable Securities or portions thereof validly
      tendered and not properly withdrawn pursuant to the Exchange Offer; and

(ii)  deliver, or cause to be delivered, to the Trustee for cancellation all
      Registrable Securities or portions thereof so accepted for exchange by the
      Company and issue, and cause the Trustee to promptly authenticate and
      deliver to each Holder, Exchange Securities equal in principal amount to
      the principal amount of the Registrable Securities surrendered by such
      Holder.

      The Company and the Guarantors shall use their reasonable best efforts to
complete the Exchange Offer as provided above and shall comply with the
applicable requirements of the Securities Act, the Exchange Act and other
applicable laws and regulations in connection with the Exchange Offer. The
Exchange Offer shall not be subject to any conditions, other than that the
Exchange Offer does not violate any applicable law or applicable interpretations
of the Staff.

      (b) In the event that (i) the Company and the Guarantors determine that
the Exchange Offer Registration provided for in Section 2(a) above is not
available or may not be completed as soon as practicable after the last Exchange
Date because it would violate any applicable law or applicable interpretations
of the Staff, (ii) the Exchange Offer is not for any other reason completed by
December 23, 2004 or (iii) upon receipt of a written request (a "Shelf Request")
from any Initial Purchaser representing that it holds Registrable Securities
that are ineligible to be exchanged in the Exchange Offer, the Company and the
Guarantors shall use their reasonable best efforts to cause to be filed as soon
as practicable after such determination, date or Shelf Request, as the case may
be, a Shelf Registration Statement providing for the sale of all the Registrable
Securities by the Holders thereof and to have such Shelf Registration Statement
declared effective by the SEC.

                                       6



      In the event that the Company and the Guarantors are required to file a
Shelf Registration Statement pursuant to clause (iii) of the preceding sentence,
the Company and the Guarantors shall use their reasonable best efforts to file
and have declared effective by the SEC both an Exchange Offer Registration
Statement pursuant to Section 2(a) with respect to all Registrable Securities
and a Shelf Registration Statement (which may be a combined Registration
Statement with the Exchange Offer Registration Statement) with respect to offers
and sales of Registrable Securities held by the Initial Purchasers after
completion of the Exchange Offer.

      The Company and the Guarantors agree to use their reasonable best efforts
to keep the Shelf Registration Statement continuously effective until the
expiration of the period referred to in Rule 144(k) (or any similar rule then in
force, but not Rule 144A) under the Securities Act with respect to the
Registrable Securities or such shorter period that will terminate when all the
Registrable Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement (the "Shelf Effectiveness
Period"). The Company and the Guarantors further agree to supplement or amend
the Shelf Registration Statement and the related Prospectus if required by the
rules, regulations or instructions applicable to the registration form used by
the Company for such Shelf Registration Statement or by the Securities Act or by
any other rules and regulations thereunder for shelf registration or if
reasonably requested by a Holder of Registrable Securities with respect to
information relating to such Holder, and to use their reasonable best efforts to
cause any such amendment to become effective and such Shelf Registration
Statement and Prospectus to become usable as soon as thereafter practicable. The
Company and the Guarantors agree to furnish to the Holders of Registrable
Securities copies of any such supplement or amendment promptly after its being
used or filed with the SEC.

      (c) The Company and the Guarantors shall pay all Registration Expenses in
connection with any registration pursuant to Section 2(a) or Section 2(b)
hereof. Each Holder shall pay all underwriting discounts and commissions,
brokerage commissions and transfer taxes, if any, relating to the sale or
disposition of such Holder's Registrable Securities pursuant to the Shelf
Registration Statement.

      (d) An Exchange Offer Registration Statement pursuant to Section 2(a)
hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared effective by
the SEC.

      In the event that either the Exchange Offer is not completed or the Shelf
Registration Statement, if required pursuant to Section 2(b)(i) or 2(b)(ii)
hereof, is not declared effective on or prior to December 23, 2004 (the "Target
Registration Date"), the interest rate on the Registrable Securities will be
increased by (i) 0.25% per annum for the first 90-day period immediately
following the Target Registration Date and (ii) an additional 0.25% per annum
with respect to each subsequent 90-day period, in each case until the Exchange
Offer is completed or the Shelf Registration Statement, if required hereby, is
declared effective by the SEC or the Securities become freely tradable under

                                       7



the Securities Act up to a maximum of 1.00% per annum of additional interest. In
the event the Company receives a Shelf Request pursuant to Section 2(b)(iii),
and the Shelf Registration Statement required to be filed thereby is not
declared effective by the later of (x) November 23, 2004 or (y) 90 days after
the delivery of such Shelf Request (such later date, the "Shelf Additional
Interest Date"), then the interest rate on the Registrable Securities will be
increased by (i) 0.25% per annum for the first 90-day period payable commencing
from one day after the Shelf Additional Interest Date and (ii) an additional
0.25% per annum with respect to each subsequent 90-day period, in each case
until the Shelf Registration Statement is declared effective, up to a maximum of
1.00% per annum of additional interest.

      If the Shelf Registration Statement, if required hereby, has been declared
effective and thereafter either ceases to be effective or the Prospectus
contained therein ceases to be usable at any time during the Shelf Effectiveness
Period, and such failure to remain effective or usable exists for more than 45
days (whether or not consecutive) in any 12-month period, then the interest rate
on the Registrable Securities will be increased by (i) 0.25% per annum for the
first 90-day period commencing on the 31st day in such 12-month period, and (ii)
an additional 0.25% per annum with respect to each subsequent 90-day period, in
each case ending on such date that the Shelf Registration Statement has again
been declared effective or the Prospectus again becomes usable up to a maximum
of 1.00% per annum of additional interest.

      (e) Without limiting the remedies available to the Initial Purchasers and
the Holders, the Company and the Guarantors acknowledge that any failure by the
Company or the Guarantors to comply with their obligations under Section 2(a)
and Section 2(b) hereof may result in material irreparable injury to the Initial
Purchasers or the Holders for which there is no adequate remedy at law, that it
will not be possible to measure damages for such injuries precisely and that, in
the event of any such failure, the Initial Purchasers or any Holder may obtain
such relief as may be required to specifically enforce the Company's and the
Guarantors' obligations under Section 2(a) and Section 2(b) hereof (it being
understood that any relief or damages recovered shall not include relief or
damages beyond those described in this Section 2(e) and Section 2(d) hereof) .

      3. Registration Procedures. (a) In connection with their obligations
pursuant to Section 2(a) and Section 2(b) hereof, the Company and the Guarantors
shall as expeditiously as possible:

      (i) prepare and file with the SEC a Registration Statement on the
appropriate form under the Securities Act, which form (x) shall be selected by
the Company and the Guarantors, (y) shall, in the case of a Shelf Registration,
be available for the sale of the Registrable Securities by the Holders thereof
and (z) shall comply as to form in all material respects with the requirements
of the applicable form and include all financial statements required by the SEC
to be filed therewith; and use their reasonable best efforts to cause such
Registration Statement to become effective and remain effective for the
applicable period in accordance with Section 2 hereof;

                                       8



      (ii) prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such

Holder, counsel or Underwriter may reasonably request, in order to facilitate
the sale or other disposition of the Registrable Securities thereunder; and the
Company and the Guarantors consent to the use of such Prospectus and any
amendment or supplement thereto in accordance with applicable law by each of the
Holders of Registrable Securities and any such Underwriters in connection with

described in such Prospectus or any amendment or supplement thereto in
accordance with applicable law;

      (iv) use their reasonable best efforts to register or qualify the
Registrable Securities under all applicable state securities or blue sky laws of
such jurisdictions as any Holder of Registrable Securities covered by a
Registration Statement shall reasonably request in writing by the time the
applicable Registration Statement is declared effective by the SEC; cooperate
with such Holders in connection with any filings required to be made with the
National Association of Securities Dealers, Inc.; and do any and all other acts
and things that may be reasonably necessary or advisable to enable each Holder
to complete the disposition in each such jurisdiction of the Registrable
Securities owned by such Holder; provided that neither the Company nor any
Guarantor shall be required to (1) qualify as a foreign corporation or other
entity or as a dealer in securities in any such jurisdiction where it would not
otherwise be required to so qualify, (2) take any action that would subject it
to service of process in any such jurisdiction or (3) subject itself to taxation
in any such jurisdiction if it is not so subject;

      (v) notify counsel for the Initial Purchasers and, in the case of a Shelf
Registration, notify each Holder of Registrable Securities and counsel for such
Holders promptly and, if requested by any such Holder or counsel, confirm such
advice in writing (1) when a Registration Statement has become effective and

suspending the effectiveness of a Registration Statement or the initiation of

                                       9

covered thereby, the representations and warranties of the Company or any
Guarantor contained in any underwriting agreement, securities sales agreement or
other similar agreement, if any, relating to an offering of such Registrable
Securities cease to be true and correct in all material respects or if the
Company or any Guarantor 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, (5) of the
happening of any event during the period a Shelf Registration Statement is
effective that makes any statement made in such Shelf Registration Statement or
the related Prospectus untrue in any material respect or that requires the
making of any changes in such Shelf Registration Statement or Prospectus in
order to make the statements therein not misleading and (6) of any determination
by the Company or any Guarantor that a post-effective amendment to a
Registration Statement would be appropriate;

contemplated by Section 3(a)(v)(5) hereof, use their reasonable best efforts to
prepare and file with the SEC a supplement or post-effective amendment to such
Shelf 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 purchasers of the Registrable Securities, such
Prospectus will not contain any untrue statement of a material fact or omit to
state a material fact necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading; and the Company
and the Guarantors shall notify the Holders of Registrable Securities to suspend
use of the Prospectus as promptly as practicable after the occurrence of such an
event, and such Holders hereby agree to suspend use of the Prospectus until the
Company and the Guarantors have amended or supplemented the Prospectus to
correct such

                                       10



misstatement or omission or until the Company and the Guarantors notify the
Holders that the Prospectus may once again be used;

Purchasers and their counsel (and, in the case of a Shelf Registration

pertinent financial and other records, documents and properties of the Company
and the Guarantors, and cause the respective officers, directors and employees
of the Company and the Guarantors to supply all information reasonably requested
by any such Inspector, Underwriter, attorney or accountant in connection with a
Shelf Registration Statement; provided that if any such information is
identified by the Company or any Guarantor as being confidential or

                                       11



proprietary, each Person receiving such information shall take such actions as
are reasonably necessary to protect the confidentiality of such information to
the extent such action is otherwise not inconsistent with, an impairment of or
in derogation of the rights and interests of any Inspector, Holder or
Underwriter;

      (xiv) in the case of a Shelf Registration, use their reasonable best
efforts to cause all Registrable Securities to be listed on any securities
exchange or any automated quotation system on which the 9-1/4% Senior Notes due
2011 are then listed if requested by the Majority Holders, to the extent such
Registrable Securities satisfy applicable listing requirements;

      (xv) if reasonably requested by any Holder of Registrable Securities
covered by a Shelf Registration Statement, promptly include in a Prospectus
supplement or post-effective amendment such information with respect to such
Holder as such Holder reasonably requests to be included therein and make all
required filings of such Prospectus supplement or such post-effective amendment
as soon as the Company has received notification of the matters to be so
included in such filing; and

      (xvi) in the case of a Shelf Registration, enter into such customary
agreements and take all such other actions in connection therewith (including
those requested by the Holders of a majority in principal amount of the
Registrable Securities being sold) in order to expedite or facilitate the
disposition of such Registrable Securities including, but not limited to, an
Underwritten Offering and in such connection, (1) to the extent possible, make
such representations and warranties to the Holders and any Underwriters of such
Registrable Securities with respect to the business of the Company and its
subsidiaries and the Registration Statement, Prospectus and documents
incorporated by reference or deemed incorporated by reference, if any, in each
case, in form, substance and scope as are customarily made by issuers to
underwriters in underwritten offerings and confirm the same if and when
requested, (2) obtain opinions of counsel to the Company and the Guarantors
(which counsel and opinions, in form, scope and substance, shall be reasonably
satisfactory to the Holders and such Underwriters and their respective counsel)
addressed to each selling Holder and Underwriter of Registrable Securities,
covering the matters customarily covered in opinions requested in underwritten
offerings, (3) obtain "comfort" letters from the independent registered public
accountants of the Company and the Guarantors (and, if necessary, any other
registered public accountants of any subsidiary of the Company or any Guarantor,
or of any business acquired by the Company or any Guarantor for which financial
statements and financial data are or are required to be included in the
Registration Statement) addressed to each selling Holder and Underwriter of
Registrable Securities, such letters to be in customary form and covering
matters of the type customarily covered in "comfort" letters in connection with
underwritten offerings and (4) deliver such documents and certificates as may be
reasonably requested by the Holders of a majority in principal amount of the
Registrable Securities being sold or the Underwriters, and which are customarily
delivered in underwritten offerings, to evidence the continued validity of the
representations and warranties of the Company and the Guarantors made pursuant
to clause (1) above and to

                                       12



evidence compliance with any customary conditions contained in an underwriting
agreement.

      (b) In the case of a Shelf Registration Statement, the Company may require
each Holder of Registrable Securities to furnish to the Company such information
regarding such Holder and the proposed disposition by such Holder of such
Registrable Securities as the Company and the Guarantors may from time to time
reasonably request in writing, and the Company may exclude from such
registration the Registrable Securities of any Holder that fails to furnish
information within a reasonable time after receiving such request.

      (c) In the case of a Shelf Registration Statement, each Holder of
Registrable Securities agrees that, upon receipt of any notice from the Company
and the Guarantors of the happening of any event of the kind described in
Section 3(a)(v)(3) or 3(a)(v)(5) hereof, such Holder will forthwith discontinue
disposition of Registrable Securities pursuant to the Shelf Registration
Statement until such Holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 3(a)(ix) hereof and, if so directed
by the Company and the Guarantors, such Holder will deliver to the Company and
the Guarantors all copies in its possession, other than permanent file copies
then in such Holder's possession, of the Prospectus covering such Registrable
Securities that is current at the time of receipt of such notice.

      (d) If the Company and the Guarantors shall give any notice pursuant to
Section 3(c) hereof to suspend the disposition of Registrable Securities
pursuant to a Shelf Registration Statement, the Company and the Guarantors shall
extend the period during which such Shelf Registration Statement shall be
maintained effective pursuant to this Agreement 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 the Holders of such Registrable Securities shall have received
copies of the supplemented or amended Prospectus necessary to resume such
dispositions. The Company and the Guarantors may give any such notice only twice
during any 365-day period and any such suspensions shall not exceed 45 days for
each suspension and there shall not be more than two suspensions in effect
during any 365-day period.

      (e) The Holders of Registrable Securities covered by a Shelf Registration
Statement who desire to do so may sell such Registrable Securities in an
Underwritten Offering. In any such Underwritten Offering, the investment bank or
investment banks and manager or managers (each an "Underwriter") that will
administer the offering will be selected by the Holders of a majority in
principal amount of the Registrable Securities included in such offering.

      4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff has
taken the position that any broker-dealer that receives Exchange Securities for
its own account in the Exchange Offer in exchange for Securities that were
acquired by such broker-dealer as a result of market-making or other trading
activities (a "Participating Broker-Dealer") may be deemed to be an
"underwriter" within the meaning of the

                                       13



Securities Act and must deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such Exchange Securities.

      The Company and the Guarantors understand that it is the Staff's position
that if the Prospectus contained in the Exchange Offer Registration Statement
includes a plan of distribution containing a statement to the above effect and
the means by which Participating Broker-Dealers may resell the Exchange
Securities, without naming the Participating Broker-Dealers or specifying the
amount of Exchange Securities owned by them, such Prospectus may be delivered by
Participating Broker-Dealers to satisfy their prospectus delivery obligation
under the Securities Act in connection with resales of Exchange Securities for
their own accounts, so long as the Prospectus otherwise meets the requirements
of the Securities Act.

      (b) In light of the above, and notwithstanding the other provisions of
this Agreement, the Company and the Guarantors agree to amend or supplement the
Prospectus contained in the Exchange Offer Registration Statement for a period
of up to 90 days after the last Exchange Date (as such period may be extended
pursuant to Section 3(d) of this Agreement), if requested by the Initial
Purchasers or by one or more Participating Broker-Dealers, in order to expedite
or facilitate the disposition of any Exchange Securities by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section
4(a) above; provided that the Company and the Guarantors shall be obligated (x)
with respect to Participating Broker-Dealers that consent, to deal only with one
entity representing such Participating Broker-Dealers, (y) to pay the fees and
expenses of only one counsel representing the Participating Broker-Dealers,
which shall be counsel to the Initial Purchasers unless such counsel elects not
to so act and (z) to cause to be delivered only one, if any, "comfort" letter
with respect to the Prospectus in the form existing on the last Exchange Date
and with respect to each subsequent amendment or supplement, if any, effected
during the period specified in this Section 4(b). The Company and the Guarantors
further agree that Participating Broker-Dealers shall be authorized to deliver
such Prospectus during such period in connection with the resales contemplated
by this Section 4.

      (c) The Initial Purchasers shall have no liability to the Company, any
Guarantor or any Holder with respect to any request that they may make pursuant
to Section 4(b) above.

      5. Indemnification and Contribution. (a) The Company and each Guarantor,
jointly and severally, agree to indemnify and hold harmless each Initial
Purchaser and each Holder, their respective affiliates, directors and officers
and each Person, if any, who controls any Initial Purchaser or any Holder within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act, from and against any and all losses, claims, damages and liabilities
(including, without limitation, legal fees and other expenses incurred in
connection with any suit, action or proceeding or any claim asserted, as such
fees and expenses are incurred), that arise out of, or are based upon, any
untrue statement or alleged untrue statement of a material fact contained in any
Registration Statement or any Prospectus or any omission or alleged omission to
state therein a material fact required to be stated therein or necessary in
order to make the statements

                                       14



therein, in the light of the circumstances under which they were made, not
misleading, except insofar as such losses, claims, damages or liabilities arise
out of, or are based upon, any untrue statement or omission or alleged untrue
statement or omission made in reliance upon and in conformity with any
information relating to any Initial Purchaser or information relating to any
Holder furnished to the Company in writing through JPMorgan or any selling
Holder expressly for use therein. In connection with any Underwritten Offering
permitted by Section 3, the Company and the Guarantors, jointly and severally,
will also indemnify the Underwriters, if any, selling brokers, dealers and
similar securities industry professionals participating in the distribution,
their respective affiliates and each Person who controls such Persons (within
the meaning of the Securities Act and the Exchange Act) to the same extent as
provided above with respect to the indemnification of the Holders, if requested
in connection with any Registration Statement.

      (b) Each Holder agrees, severally and not jointly, to indemnify and hold
harmless the Company, the Guarantors, the Initial Purchasers and the other
selling Holders, the directors of the Company and the Guarantors, each officer
of the Company and the Guarantors who signed the Registration Statement and each
Person, if any, who controls the Company, the Guarantors, any Initial Purchaser
and any other selling Holder within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act to the same extent as the indemnity set
forth in paragraph (a) above, but only with respect to any losses, claims,
damages or liabilities that arise out of, or are based upon, any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with any information relating to such Holder furnished to
the Company in writing by such Holder expressly for use in any Registration
Statement and any Prospectus.

      (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnification may be sought pursuant to either
paragraph (a) or (b) above, such Person (the "Indemnified Person") shall
promptly notify the Person against whom such indemnification may be sought (the
"Indemnifying Person") in writing; provided that the failure to notify the
Indemnifying Person shall not relieve it from any liability that it may have
under this Section 5 except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and
provided, further, that the failure to notify the Indemnifying Person shall not
relieve it from any liability that it may have to an Indemnified Person
otherwise than under this Section 5. If any such proceeding shall be brought or
asserted against an Indemnified Person and it shall have notified the
Indemnifying Person thereof, the Indemnifying Person shall retain counsel
reasonably satisfactory to the Indemnified Person to represent the Indemnified
Person and any others entitled to indemnification pursuant to this Section 5
that the Indemnifying Person may designate in such proceeding and shall pay the
fees and expenses of such counsel related to such proceeding, as incurred. In
any such proceeding, any Indemnified Person shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such Indemnified Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually

                                       15



agreed to the contrary; (ii) the Indemnifying Person has failed within a
reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person; (iii) the Indemnified Person shall have reasonably concluded that there
may be legal defenses available to it that are different from or in addition to
those available to the Indemnifying Person; or (iv) the named parties in any
such proceeding (including any impleaded parties) include both the Indemnifying
Person and the Indemnified Person and representation of both parties by the same
counsel would be inappropriate due to actual or potential differing interests
between them. It is understood and agreed that the Indemnifying Person shall
not, in connection with any proceeding or related proceeding in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all Indemnified Persons, and that all
such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm (x) for any Initial Purchaser, its affiliates, directors and
officers and any control Persons of such Initial Purchaser shall be designated
in writing by JPMorgan, (y) for any Holder, directors and officers and any
control Persons of such Holder shall be designated in writing by the Majority
Holders and (z) in all other cases shall be designated in writing by the
Company. The Indemnifying Person shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Indemnifying
Person agrees to indemnify each Indemnified Person from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested
that an Indemnifying Person reimburse the Indemnified Person for fees and
expenses of counsel as contemplated by this paragraph, the Indemnifying Person
shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by the Indemnifying Person of such request and (ii) the Indemnifying
Person shall not have reimbursed the Indemnified Person in accordance with such
request prior to the date of such settlement. No Indemnifying Person shall,
without the written consent of the Indemnified Person, effect any settlement of
any pending or threatened proceeding in respect of which any Indemnified Person
is or could have been a party and indemnification could have been sought
hereunder by such Indemnified Person, unless such settlement (A) includes an
unconditional release of such Indemnified Person, in form and substance
reasonably satisfactory to such Indemnified Person, from all liability on claims
that are the subject matter of such proceeding and (B) does not include any
statement as to or any admission of fault, culpability or a failure to act by or
on behalf of any Indemnified Person.

      (d) If the indemnification provided for in paragraphs (a) and (b) above is
unavailable to an Indemnified Person or insufficient in respect of any losses,
claims, damages or liabilities referred to therein, then each Indemnifying
Person under such paragraph, in lieu of indemnifying such Indemnified Person
thereunder, shall contribute to the amount paid or payable by such Indemnified
Person as a result of such losses, claims, damages or liabilities (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Guarantors from the offering of the Securities and the Exchange
Securities, on the one hand, and by the Holders from receiving Securities or
Exchange Securities registered under the Securities Act, on the other hand, or
(ii) if the allocation provided by clause (i) is not permitted by applicable
law, in such

                                       16



proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) but also the relative fault of the Company and the Guarantors
on the one hand and the Holders on the other in connection with the statements
or omissions that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations. The relative fault of the
Company and the Guarantors on the one hand and the Holders 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 and the
Guarantors or by the Holders and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.

      (e) The Company, the Guarantors and the Holders agree that it would not be
just and equitable if contribution pursuant to this Section 5 were determined by
pro rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above. The amount paid or
payable by an Indemnified Person as a result of the losses, claims, damages and
liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred
by such Indemnified Person in connection with any such action or claim.
Notwithstanding the provisions of this Section 5, in no event shall a Holder be
required to contribute any amount in excess of the amount by which the total
price at which the Securities or Exchange Securities sold by such Holder exceeds
the amount of any 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.

      (f) The remedies provided for in this Section 5 are not exclusive and
shall not limit any rights or remedies that may otherwise be available to any
Indemnified Person at law or in equity.

      (g) The indemnity and contribution provisions contained in this Section 5
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
the Initial Purchasers or any Holder or any Person controlling any Initial
Purchaser or any Holder, or by or on behalf of the Company or the Guarantors or
the officers or directors of or any Person controlling the Company or the
Guarantors, (iii) acceptance of any of the Exchange Securities and (iv) any sale
of Registrable Securities pursuant to a Shelf Registration Statement.

      6. General.

      (a) No Inconsistent Agreements. The Company and the Guarantors represent,
warrant and agree that (i) 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 any other outstanding securities issued or guaranteed by the Company
or any Guarantor under any

                                       17



other agreement and (ii) neither the Company nor any Guarantor has entered into,
or on or after the date of this Agreement will enter into, any agreement that is
inconsistent with the rights granted to the Holders of Registrable Securities in
this Agreement or otherwise conflicts with the provisions hereof.

      (b) Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company and the Guarantors have obtained the written consent of
Holders of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or consent; provided that no amendment, modification, supplement, waiver
or consent to any departure from the provisions of Section 5 hereof shall be
effective as against any Holder of Registrable Securities unless consented to in
writing by such Holder. Any amendments, modifications, supplements, waivers or
consents pursuant to this Section 6(b) shall be by a writing executed by each of
the parties hereto.

      (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to the Initial
Purchasers, the address set forth in the Purchase Agreement, with copies to
Arthur D. Robinson, Esq., Simpson Thacher & Bartlett LLP, 425 Lexington Avenue,
New York, New York 10017, Telecopy No.: (212) 455-2502, Confirm No.: (212)
455-2500; (ii) if to the Company and the Guarantors, initially at the Company's
address set forth in the Purchase Agreement and thereafter at such other
address, notice of which is given in accordance with the provisions of this
Section 6(c); and (iii) to such other persons at their respective addresses as
provided in the Purchase Agreement and thereafter at such other address, notice
of which is given in accordance with the provisions of this Section 6(c). All
such notices and communications shall be deemed to have been duly given: at the
time delivered by hand, if personally delivered; five Business Days after being
deposited in the mail, postage prepaid, if mailed; when answered back, if
telexed; when receipt is acknowledged, if telecopied; and on the next Business
Day if timely delivered to an air courier guaranteeing overnight delivery.
Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the Trustee, at the
address specified in the Indenture.

      (d) 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 limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement or the Indenture. If any
transferee of any Holder shall acquire Registrable Securities in any manner,
whether by operation of law or otherwise, such Registrable Securities shall

                                       18



be held subject to all 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 and such Person shall be entitled to receive the benefits hereof. The
Initial Purchasers (in their capacity as Initial Purchasers) shall have no
liability or obligation to the Company or the Guarantors with respect to any
failure by a Holder to comply with, or any breach by any Holder of, any of the
obligations of such Holder under this Agreement.

      (e) Third Party Beneficiaries. Each Holder shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights or the rights of
other Holders hereunder.

      (f) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

      (g) Headings. The headings in this Agreement are for convenience of
reference only, are not a part of this Agreement and shall not limit or
otherwise affect the meaning hereof.

      (h) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

      (j) Miscellaneous. This Agreement contains the entire agreement between
the parties relating to the subject matter hereof and supersedes all oral
statements and prior writings with respect thereto. If any term, provision,
covenant or restriction contained in this Agreement is held by a court of
competent jurisdiction to be invalid, void or unenforceable or against public
policy, the remainder of the terms, provisions, covenants and restrictions
contained herein shall remain in full force and effect and shall in no way be
affected, impaired or invalidated. The Company, the Guarantors and the Initial
Purchasers shall endeavor in good faith negotiations to replace the invalid,
void or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the invalid, void or unenforceable
provisions.

                                       19
