         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

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


                                       5
<PAGE>

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 210 days after the Closing Date
or (iii) the Exchange Offer has been completed and in the opinion of counsel for
the Initial Purchasers a Registration Statement must be filed and a Prospectus
must be delivered by the Initial Purchasers in connection with any offering or
sale of Registrable Securities held by the Initial Purchasers, 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 notice of such opinion of
counsel is given to the Company, as the case may be, a Shelf Registration
Statement providing for the sale of all the Registrable Securities by the
Holders thereof (or Initial Purchasers that are holders thereof in the case of a
Shelf Registration Statement filed pursuant to clause (iii) of this sentence)
and to have such Shelf Registration Statement declared effective by the SEC.

         In the event that the Company and the Guarantors are required to file a
Shelf Registration Statement solely as a result of the matters referred to in
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) 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 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 the registration pursuant to Section 2(a) and Section 2(b)
hereof. Each Holder shall pay all underwriting discounts and 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; provided that if, after it has been declared effective, the offering of
Registrable Securities pursuant to a Shelf Registration Statement is interfered
with by any stop order, injunction or other order or requirement of the


                                       6
<PAGE>

SEC or any court or other governmental or regulatory agency or body, such
Registration Statement will be deemed not to have become effective during the
period of such interference until the offering of Registrable Securities
pursuant to such Registration Statement may legally resume.


         In the event that either the Exchange Offer is not completed or a Shelf
Registration Statement, if required hereby, is not declared effective within 210
days of the Closing Date, the interest rate on the Registrable Securities will
be increased by 1.00% per annum 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 the Securities Act.

         (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.

to a Shelf Registration Statement or a related Prospectus or any document that
is to be incorporated by reference into a Shelf Registration Statement or a
related Prospectus, of which the Initial Purchasers and their counsel and the
Holders of Registrable Securities and their counsel shall not have previously
been advised and furnished a copy or to which the Initial Purchasers or their
counsel or the Holders or their counsel shall reasonably object;

         (k) obtain a CUSIP number for all Exchange Securities or Registrable
Securities, as the case may be, not later than the effective date of a
Registration Statement;

         (l) cause the Indenture to be qualified under the Trust Indenture Act
in connection with the registration of the Exchange Securities or Registrable

cooperate with the Trustee and the Holders to effect such changes to the
Indenture as may be required for the Indenture to be so qualified in accordance
with the terms of the Trust Indenture Act; and execute, and use their reasonable
best efforts to cause the Trustee to execute, all documents as may be required
to effect such changes and all other forms and documents required to be filed
with the SEC to enable the Indenture to be so qualified in a timely manner;

         (m) in the case of a Shelf Registration, make available for inspection
by a representative of the Holders of the Registrable Securities (an
"Inspector"), any Underwriter participating in any disposition pursuant to such
Shelf Registration Statement, and attorneys and accountants designated by the
Holders, at reasonable times and in a reasonable manner, all pertinent financial
and other records, pertinent 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 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;

         (n) 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 similar securities issued or
guaranteed by the Company or any Guarantor are then listed if requested by the
Majority Holders, to the extent such Registrable Securities satisfy applicable
listing requirements;

         (o) if reasonably requested by any Holder of Registrable Securities
covered by a Registration Statement, promptly incorporate 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
incorporated in such filing; and

         (p) 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, (i) 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, 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, (ii) 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


                                       10
<PAGE>

offerings, (iii) obtain "comfort" letters from the independent certified public
accountants of the Company and the Guarantors (and, if necessary, any other
certified public accountant 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 (iv) 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 (i) above and to evidence compliance with any customary conditions
contained in an underwriting agreement.

         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.

         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(e)(iii) or 3(e)(v) hereof, such Holder will forthwith discontinue
disposition of Registrable Securities pursuant to a Registration Statement until
such Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) 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.

         If the Company and the Guarantors shall give any such notice to suspend
the disposition of Registrable Securities pursuant to a Registration Statement,
the Company and the Guarantors shall extend the period during which the
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 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 30
days for each suspension and there shall not be more than two suspensions in
effect during any 365-day period.

         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 banker
or investment bankers and manager or managers (the "Underwriters") that will
administer the offering will be selected by the Majority Holders of the
Registrable Securities included in such offering and shall be reasonably
acceptable to the Company and the Guarantors.

Section 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 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, as would
otherwise be contemplated by Section 3(i), for a period of up to 180 days after
the last Exchange Date (as such period may be extended pursuant to the
penultimate paragraph of Section 3 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. 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; and

         (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.

Section 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 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), joint or several, arising out of or based upon any untrue statement
or alleged untrue statement of a material fact contained in any Registration
Statement or any Prospectus, or arising out of or based upon any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, except insofar as such
losses, claims, damages or liabilities are arising out of or 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 any


                                       12
<PAGE>

Holder furnished to the Company in writing through the Initial Purchasers or any
selling Holder expressly for use therein. In connection with any Underwritten
Offering permitted by Section 3, the Company and the Guarantors 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, their respective affiliates, 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 arising out of or 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. 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 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


                                       13
<PAGE>

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 and any control Persons of such Initial
Purchaser shall be designated in writing by Credit Suisse First Boston
Corporation, (y) for any Holder, its affiliates 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 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, 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 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


                                       14
<PAGE>

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 Holder their respective affiliates or any Person
controlling any Initial Purchaser or any Holder, or by or on behalf of the
Company, the Guarantors, their respective affiliates 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.

Section 6. Miscellaneous.

         (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 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.

         (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


                                       15
<PAGE>

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; and (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). 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 applicable
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. If any transferee of any
Holder shall acquire Registrable Securities in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all
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) Purchases and Sales of Securities. The Company and the Guarantors
shall not, and shall use their reasonable best efforts to cause their affiliates
(as defined in Rule 405 under the Securities Act) not to, purchase and then
resell or otherwise transfer any Registrable Securities.

         (f) 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.

         (g) 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.

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

                                       16
<PAGE>

         (i) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. THE COMPANY AND THE
GUARANTORS EACH HEREBY AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE
STATE OF NEW YORK, COUNTY OF NEW YORK, IN ANY ACTION OR PROCEEDING ARISING OUT
OF OR RELATING TO THIS AGREEMENT.

         (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. This Agreement may not be
amended or modified except by a writing executed by each of the parties hereto.
Section headings herein are for convenience only and are not a part of this
Agreement. 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.
