which such Initial Note has been disposed of in accordance with a Shelf

<PAGE>

contemplated by the Exchange Offer Registration Statement (including the
delivery of the Prospectus contained therein).

     Section 2. Holders.

     A Person is deemed to be a holder of Transfer Restricted Securities (each,
a "Holder") whenever such Person owns Transfer Restricted Securities.

     Section 3. Registered Exchange Offers.

     (a)  Unless an Exchange Offer shall not be permitted by applicable federal
law (after the procedures set forth in Section 6(a)(i) below have been complied
with), the Company and the Guarantors shall (i) cause the Exchange Offer
Registration Statement to be tiled with the Commission as soon as practicable
after the Closing Date, but in no event later than 90 days after the Closing
Date (such 90th day being the "Filing Deadline"), (ii) use their best efforts to
cause the Exchange Offer Registration Statement to become effective at the
earliest possible time, but in no event later than 210 days after the Closing
Date (such 210th day being the "Effectiveness Deadline"), (iii) in connection
with the foregoing, (A) file all pre-effective amendments to the Exchange Offer
Registration Statement as may be necessary in order to cause it to become
effective, (B) file, if applicable, a post-effective amendment to the Exchange
Offer Registration Statement pursuant to Rule 430A under the Act and (C) cause
all necessary filings, if any, in connection with the registration and
qualification of the Exchange Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer, and
(iv) upon the effectiveness of such Exchange Offer Registration Statement and
within the time period contemplated by Section 3(b) hereof, commence and
Consummate the Exchange Offer. The Exchange Offer shall be on the appropriate
form permitting (i) registration of the Exchange Notes to be offered in exchange
for the Initial Notes that are Transfer Restricted Securities and (ii) resales
of Exchange Notes by Broker-Dealers that tendered into the Exchange Offer
Initial Notes that such Broker-Dealer acquired for its own account as a result
of market making activities or other trading activities (other than Initial
Notes acquired directly from the Company or any of its Affiliates) as
contemplated by Section 3(c) below.

     (b)  The Company and the Guarantors shall use their respective best efforts
to cause the Exchange Offer Registration Statement to be effective continuously,
and shall keep the Exchange Offer open for a period of not less than the minimum
period required under applicable federal and state securities laws to Consummate
such Exchange Offer; provided, however, that in no event shall such period be
less than 20 Business Days. The Company and the Guarantors shall cause the
Exchange Offer to comply with all applicable federal and state securities

                                       5
<PAGE>

laws. No securities other than the Exchange Notes shall be included in the
Exchange Offer Registration Statement. The Company and the Guarantors shall use
their respective best efforts to cause the Exchange Offer to be Consummated on
the earliest practicable date after the Exchange Offer Registration Statement
has become effective, but in no event later than 30 business days thereafter
(such 30th business day being the "Consummation Deadline").

     (c)  The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Initial Notes acquired
directly from the Company or any Affiliate of the Company), may exchange such
Transfer Restricted Securities pursuant to the Exchange Offer. Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement. See the Shearman & Sterling no-action letter (available
July 2, 1993).

     Because such Broker-Dealer may be deemed to be an "underwriter" within the
meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with its initial sale of any Exchange
Notes received by such Broker-Dealer in the Exchange Offer, the Company and
Guarantors shall permit the use of the Prospectus contained in the Exchange
Offer Registration Statement by such Broker-Dealer to satisfy such prospectus
delivery requirement. To the extent necessary to ensure that the Prospectus
contained in the Exchange Offer Registration Statement is available for sales of
Exchange Notes by Broker-Dealers, the Company and the Guarantors agree to use
their respective best efforts to keep the Exchange Offer Registration Statement
continuously effective, supplemented, amended and current as required by and
subject to the provisions of Sections 6(a) and 6(c) hereof and in conformity
with the requirements of this Agreement, the Act and the policies, rules and
regulations of the Commission as announced from time to time, for a period of
180 days from the Consummation Deadline or such shorter period as will terminate
when all Transfer Restricted Securities covered by such Registration Statement
have been sold pursuant thereto or are no longer outstanding. The Company and
the Guarantors shall provide sufficient copies of the latest version of such
Prospectus to such Broker-Dealers, promptly upon request, and in no event later
than one day after such request, at any time during such period.

     Section 4. Shelf Registration.

                                       6
<PAGE>

         (a) Shelf Registration. If(i) the Exchange Offer is not permitted by
applicable law or Commission policy (after the Company and the Guarantors have
complied with the procedures set forth in Section 6(a)(i) below) or (ii) if any
Holder of Transfer Restricted Securities shall notify the Company within 20
Business Days following the Consummation of the Exchange Offer that (A) such
Holder was prohibited by law or Commission policy from participating in the
Exchange Offer or (B) such Holder may not resell the Exchange Notes acquired by
it in the Exchange Offer to the public without delivering a prospectus and the
Prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales by such Holder or (C) such Holder is a
Broker-Dealer and holds Initial Notes acquired directly from the Company or any
of its Affiliates, then the Company and the Guarantors shall:

                  (x) cause to be filed, on or prior to 30 days after the
         earlier of(i) the date on which the Company determines that the
         Exchange Offer Registration Statement cannot be filed as a result of
         clause 4(a)(i) above and (ii) the date on which the Company receives
         the notice specified in clause 4(a)(ii) above, (such earlier date, the
         "Filing Deadline"), a shelf registration statement pursuant to Rule 415
         under the Act (which may be an amendment to the Exchange Offer
         Registration Statement (the "Shelf Registration Statement")), relating
         to (1) all Transfer Restricted Securities with respect to which an
         Exchange Offer is not permitted in the case of clause 4(a)(i) above or
         (2) the Transfer Restricted Securities specified in any notice in the
         case of clause 4(a)(ii), and

                  (y) shall use their respective best efforts to cause such
         Shelf Registration Statement to become effective on or prior to 60 days
         after the Filing Deadline for the Shelf Registration Statement (such
         60th day the "Effectiveness Deadline").

         If, after the Company has filed an Exchange Offer Registration
Statement that satisfies the requirements of Section 3(a) above, the Company is
required to file and make effective a Shelf Registration Statement solely
because the Exchange Offer is not permitted under applicable law or Commission
policy (i.e., clause 4(a)(i) above), then the filing of the Exchange Offer
Registration Statement shall be deemed to satisfy the requirements of clause (x)
above; provided that, in such event, the Company shall remain obligated to meet
the Effectiveness Deadline set forth in clause (y).

         To the extent necessary to ensure that the Shelf Registration Statement
is available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and the other securities required
to be registered therein pursuant to Section 6(b)(ii) hereof, the Company and
the Guarantors shall

                                       7
<PAGE>

use their respective best efforts to keep any Shelf Registration Statement
required by this Section 4(a) continuously effective, supplemented, amended and
current as required by and subject to the provisions of Sections 6(b) and 6(c)
hereof and in conformity with the requirements of this Agreement, the Act and
the policies, rules and regulations of the Commission as announced from time to
time, for a period of at least two years (as extended pursuant to Section 6(d))
following the Closing Date, or such shorter period as will terminate on the
earlier of the date when all Transfer Restricted Securities covered by such
Shelf Registration Statement have been sold pursuant thereto, no longer
constitute Transfer Restricted Securities or are no longer outstanding.

         (b) Provision by Holders of Certain Information in Connection with the
ShelfRegistration Statement. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have provided all such
information which is required by rules of the Commission to be included in the
Shelf Registration Statement prior to the time it is declared effective. Each
selling Holder agrees to promptly furnish additional information required to be
disclosed in order to make the information previously furnished to the Company
by such Holder not materially misleading.

         (c) Suspension. The Company and the Guarantors will have the ability to
suspend the Shelf Registration Statement (a "Suspension Period"), if the Company
and the Guarantors determine, in their reasonable best judgment, upon written
advice of counsel, that the continued effectiveness and use of the Shelf
Registration Statement would require the disclosure of confidential information
or interfere with any financing, acquisition, reorganization or other material
transaction involving the Company. A Suspension Period shall commence on and
include the date that the Company and the Guarantors give notice that the Shelf
Registration Statement is no longer effective or the Prospectus included therein
is no longer usable for offers and sales of Transfer Restricted Securities
covered by such Registration Statement and continue until holders of such
Transfer Restricted Securities either receive the copies of the supplemented or
amended prospectus contemplated by Section 6(c) hereof or are advised in writing
by the Company and the Guarantors that use of the Prospectus may be resumed. Any
such suspensions may not exceed (i) 60 days in the aggregate in the first twelve
month period after the Closing Date, (ii) 60 days in the aggregate in the twelve
month

                                       8
<PAGE>

period immediately thereafter and (iii) 90 days in the aggregate during any
subsequent twelve month period.

         Section 5. Liquidated Damages.

         If (a) any Registration Statement required by this Agreement is not
filed with the Commission on or prior to the applicable Filing Deadline, (b) any
such Registration Statement has not been declared effective by the Commission on
or prior to the applicable Effectiveness Deadline, (c) the Exchange Offer has
not been Consummated on or prior to the Consummation Deadline or (d) any
Registration Statement required by this Agreement is filed and declared
effective but shall thereafter cease to be effective or fail to be usable
(provided that the unavailability of a Registration Statement for the use of a
Holder as a result of such Holder's failure to provide information pursuant to
Section 4(b) or make representations required by Section 6(a)(ii) shall not be
deemed to make the Registration Statement fail to be usable) for its intended
purpose (except as provided in, and during the time periods specified in,
Section 4(c)) without being succeeded within five days by a post-effective
amendment to such Registration Statement that cures such failure and that is
itself declared effective within 10 days of the filing of such post-effective
amendment (each such event referred to in clauses (a) through (d), a
"Registration Default"), then the Company and each of the Guarantors hereby
jointly and severally agree to pay to each Holder of Transfer Restricted
Securities affected thereby liquidated damages in an amount equal to $.05 per
week per $1,000 in principal amount of Transfer Restricted Securities held by
such Holder for each week or portion thereof that the Registration Default
continues for the first 90-day period immediately following the occurrence of
such Registration Default. The amount of the liquidated damages shall increase
by an additional $.05 per week per $1,000 in principal amount of Transfer
Restricted Securities with respect to each subsequent 90-day period until all
Registration Defaults have been cured, up to a maximum amount of liquidated
damages of $.25 per week per $1,000 in principal amount of Transfer Restricted
Securities; provided that the Company and the Guarantors shall in no event be
required to pay liquidated damages for more than one Registration Default at any
given time. Notwithstanding anything to the contrary set forth herein, (i) upon
filing of the Exchange Offer Registration Statement (and/or, if applicable, the
Shelf Registration Statement), in the case of clause (a) above, (ii) upon the
effectiveness of the Exchange Offer Registration Statement (and/or, if
applicable, the Shelf Registration Statement), in the case of clause (b) above,
(iii) upon Consummation of the Exchange Offer, in the case of clause (c) above,
or (iv) upon the filing of a post-effective amendment to the Registration
Statement or an additional Registration Statement that causes the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration Statement)
to again be declared effective or made usable in the case of clause (d) above,
the

                                       9
<PAGE>

liquidated damages payable with respect to the Transfer Restricted Securities as
a result of such clause (a), (b), (c) or (d), as applicable, shall cease to
accrue.

         All accrued liquidated damages shall be paid to the record Holders
entitled thereto, in the manner provided for the payment of interest in the
Indenture, on each Interest Payment Date, as more fully set forth in the
Indenture and the Notes. Notwithstanding the fact that any securities for which
liquidated damages are due cease to be Transfer Restricted Securities, all
obligations of the Company and the Guarantors to pay liquidated damages with
respect to securities shall survive until such time as such obligations with
respect to such securities shall have been satisfied in full.

         Section 6. Registration Procedures.

         (a) Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Company and the Guarantors shall (x) comply with all
applicable provisions of Section 6(c) below, (y) use their respective best
efforts to effect such exchange and to permit the resale of Exchange Notes by
Broker-Dealers that tendered in the Exchange Offer Initial Notes that such
Broker-Dealer acquired for its own account as a result of its market making
activities or other trading activities (other than Initial Notes acquired
directly from the Company or any of its Affiliates) being sold in accordance
with the intended method or methods of distribution thereof, and (z) comply with
all of the following provisions:

                  (i) If, following the date hereof there has been announced a
         change in Commission policy with respect to exchange offers such as the
         Exchange Offer, that in the reasonable opinion of counsel to the
         Company raises a substantial question as to whether the Exchange Offer
         is permitted by applicable federal law, the Company and the Guarantors
         hereby agree to seek a no-action letter or other favorable decision
         from the Commission allowing the Company and the Guarantors to
         Consummate an Exchange Offer for such Transfer Restricted Securities.
         The Company and the Guarantors hereby agree to pursue the issuance of
         such a decision to the Commission staff level but shall not be required
         to take commercially unreasonable action to effect a change of
         Commission policy. In connection with the foregoing, the Company and
         the Guarantors hereby agree to take all such other actions (other than
         such actions as may be commercially unreasonable) as may be requested
         by the Commission or otherwise required in connection with the issuance
         of such decision, including without limitation (A) participating in
         telephonic conferences with the Commission, (B) delivering to the
         Commission staff an analysis prepared by counsel to the Company setting
         forth the legal bases, if any, upon which such counsel has concluded
         that such an Exchange Offer

                                       10
<PAGE>

should be permitted and (C) diligently pursuing a resolution (which need not be
favorable) by the Commission staff.

        (ii)  As a condition to its participation in the Exchange Offer, each
Holder of Transfer Restricted Securities (including, without limitation, any
Holder who is a Broker Dealer) shall furnish, upon the request of the Company,
prior to the Consummation of the Exchange Offer, a written representation to the
Company and the Guarantors (which may be contained in the letter of transmittal
contemplated by the Exchange Offer Registration Statement) to the effect that
(A) such Holder is not an Affiliate of the Company or a Broker-Dealer tendering
Initial Notes acquired directly from the Company for its own account, (B) such
Holder will have no arrangement or understanding with any person to participate
in the distribution of the Initial Notes or the Exchange Notes within the
meaning of the Act, (C) if the Holder is not a Broker-Dealer or is a
Broker-Dealer but will not receive Exchange Notes for its own account in
exchange for Initial Notes, neither the Holder nor any such other Person is
engaged in or intends to participate in a distribution of the Exchange Notes,
and (D) any Exchange Notes received by such Holder will be acquired in the
ordinary course of its business. If the Holder is a Broker-Dealer that will
receive Exchange Notes for its own account in exchange for Initial Notes, it
will represent that the Initial Notes to be exchanged for the Exchange Notes
were acquired by it as a result of market-making activities or other trading
activities, and will acknowledge that it will deliver a prospectus meeting the
requirements of the Act in connection with any resale of such Exchange Notes. It
is understood that, by acknowledging that it will deliver, and by delivering, a
prospectus meeting the requirements of the Act in connection with any resale of
such Exchange Notes, the Holder is not admitting that it is an "underwriter"
within the meaning of the Act.

        (iii) Prior to effectiveness of the Exchange Offer Registration
Statement, the Company and the Guarantors shall provide a supplemental letter to
the Commission (A) stating that the Company and the Guarantors are registering
the Exchange Offer in reliance on the position of the Commission enunciated in
Exxon Capital Holdings Corporation (available May 13, 1988), Morgan Stanley and
Co., Inc. (available June 5, 1991) as interpreted in the Commission's letter to
Shearman & Sterling dated July 2, 1993, and, if applicable, any no-action letter
obtained pursuant to Section 6(a)(i) above, (B) including a representation that
neither the Company nor any of the Guarantors has entered into any arrangement
or understanding with any Person to distribute the Exchange Notes to be received
in the Exchange Offer and that, to the best of the Company's and each
Guarantor's information and belief, each Holder

                                       11
<PAGE>

         participating in the Exchange Offer is acquiring the Exchange Notes in
         its ordinary course of business and has no arrangement or understanding
         with any Person to participate in the distribution of the Exchange
         Notes received in the Exchange Offer and (C) any other undertaking or
         representation required by the Commission as set forth in any no-action
         letter obtained pursuant to Section 6(a)(i) above, if applicable.

         (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company and the Guarantors shall

                 (i)  comply with all the provisions of Section 6(c) below and
         use their respective reasonable best efforts to effect such
         registration to permit the sale of the Transfer Restricted Securities
         being sold in accordance with the intended method or methods of
         distribution thereof (as indicated in the information furnished to the
         Company pursuant to Section 4(b) hereof), and pursuant thereto the
         Company and the Guarantors will prepare and file with the Commission a
         Registration Statement relating to the registration on any appropriate
         form under the Act, which form shall be available for the sale of the
         Transfer Restricted Securities in accordance with the intended method
         or methods of distribution thereof within the time periods and
         otherwise in accordance with the provisions hereof, and

                 (ii) issue, upon the request of any Holder or purchaser of
         Initial Notes covered by any Shelf Registration Statement contemplated
         by this Agreement, Exchange Notes having an aggregate principal amount
         equal to the aggregate principal amount of Initial Notes sold pursuant
         to the Shelf Registration Statement and surrendered to the Company for
         cancellation; the Company shall register Exchange Notes on the Shelf
         Registration Statement for this purpose and issue the Exchange Notes to
         the purchaser(s) of securities subject to the Shelf Registration
         Statement in the names as such purchaser(s) shall designate.

         (c)     General Provisions. In connection with any Registration
Statement and any related Prospectus required by this Agreement, the Company and
the Guarantors shall:

                 (i)  use their respective best efforts to keep such
         Registration Statement continuously effective and provide all requisite
         financial statements for the period specified in Section 3 or 4 of this
         Agreement, as applicable. Upon the occurrence of any event that would
         cause any such Registration Statement or the Prospectus contained
         therein (A) to contain an untrue statement of material fact or omit to
         state any material fact necessary to make the statements therein not
         misleading or (B) not to be effective and usable for resale of Transfer
         Restricted Securities during the

                                       12
<PAGE>

period required by this Agreement, the Company and the Guarantors shall, subject
to Section 4(c), tile promptly an appropriate amendment to such Registration
Statement curing such defect, and, if Commission review is required, use their
respective reasonable best efforts to cause such amendment to be declared
effective as soon as practicable.

         (ii)  prepare and file with the Commission such amendments and post-
effective amendments to the applicable Registration Statement as may be
necessary to keep such Registration Statement effective for the applicable
period set forth in Section 3 or 4 hereof, as the case may be; cause the
Prospectus to be supplemented by any required Prospectus supplement, and as so
supplemented to be filed pursuant to Rule 424 under the Act, and to comply fully
with Rules 424,430A and 462, as applicable, under the Act in a timely manner;
and comply with the provisions of the Act with respect to the disposition of all
securities covered by such Registration Statement during the applicable period
in accordance with the intended method or methods of distribution by the sellers
thereof set forth in such Registration Statement or supplement to the
Prospectus;

         (iii) advise the Initial Purchasers and, in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, promptly and,
if requested by such Holder, confirm such advice in writing, (A) when the
Prospectus or any Prospectus supplement or post-effective amendment has been
filed, and, with respect to any applicable Registration Statement or any
post-effective amendment thereto, when the same has become effective, (B) of any
request by the Commission for amendments to the Registration Statement or
amendments or supplements to the Prospectus or for additional information
relating thereto, (C) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement under the Act or of
the suspension by any state securities commission of the qualification of the
Transfer Restricted Securities for offering or sale in any jurisdiction, or the
initiation of any proceeding for any of the preceding purposes, and (D) of the
existence of any fact or the happening of any event that makes any statement of
a material fact made in the Registration Statement, the Prospectus, any
amendment or supplement thereto or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in
the Registration Statement in order to make the statements therein not
misleading, or that requires the making of any additions to or changes in the
Prospectus in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. If at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, or any state securities commission or other regulatory
authority shall issue an order

                                       13
<PAGE>

suspending the qualification or exemption from qualification of the Transfer
Restricted Securities under state securities or Blue Sky laws, the Company and
the Guarantors shall use their respective best efforts to obtain the withdrawal
or lifting of such order at the earliest possible time;

         (iv) subject to Section 4(c), if any fact or event contemplated by
Section 6(c)(iii)(D) above shall exist or have occurred, prepare a supplement or
post-effective amendment to the Registration Statement or related Prospectus or
any document incorporated therein by reference or file any other required
document so that, as thereafter delivered to the purchasers of Transfer
Restricted Securities, the Prospectus will not contain an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading;

         (v)  furnish to the Initial Purchasers and, in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, in connection
with such exchange or sale, if any, before filing with the Commission, copies of
any Registration Statement or any Prospectus included therein or any amendments
or supplements to any such Registration Statement or Prospectus (including all
documents incorporated by reference after the initial filing of such
Registration Statement), which documents will be subject to the review and
comment of such Holders in connection with such sale, if any, for a period of at
least five Business Days, and the Company will not file any such Registration
Statement or Prospectus or any amendment or supplement to any such Registration
Statement or Prospectus (including all such documents incorporated by reference)
to which such Holders shall reasonably object within five Business Days after
the receipt thereof. A Holder shall be deemed to have reasonably objected to
such filing if such Registration Statement, amendment, Prospectus or supplement,
as applicable, as proposed to be filed, contains an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein not misleading or fails to comply with the applicable
requirements of the Act;

         (vi) promptly prior to the filing of any document that is to be
incorporated by reference into a Registration Statement or Prospectus, provide
copies of such document to the Initial Purchasers and in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, in connection
with such exchange or sale, if any, make the Company's and each Guarantor's
representatives available for discussion of such document and other customary
due diligence matters, and include such information in such document prior to
the filing thereof as the Initial Purchasers or such Holders may reasonably
request;

                                       14
<PAGE>

         (vii)   make available, at reasonable times, for inspection by the
Initial Purchasers and, in the case of a Shelf Registration Statement, each
Holder of securities covered thereby, and the designated counsel or any
accountant retained by such Holders, all financial and other records, pertinent
corporate documents of the Company and each Guarantor and cause the Company's
and each Guarantor's officers, directors and employees to supply all information
reasonably requested by any such Initial Purchaser, Holder, attorney or
accountant in connection with such Registration Statement or any post-effective
amendment thereto subsequent to the filing thereof and prior to its
effectiveness; provided, however, that such persons shall first agree in writing
with the Company and the Guarantors that any information that is reasonably and
in good faith designated by the Company and the Guarantors in writing as
confidential at the time of delivery of such information shall be kept
confidential by such persons, unless (i) disclosure of such information is
required by court or administrative order or is necessary to respond to
inquiries of regulatory authorities, (ii) disclosure of such information is
required by law (including any disclosure requirements pursuant to federal
securities laws in connection with the filing of such Registration Statement or
the use of any Prospectus), (iii) such information becomes generally available
to the public other than as a result of a disclosure or failure to safeguard
such information by such person or (iv) such information becomes available to
such person from a source other than the Company and its subsidiaries and such
source is not known, after due inquiry, by such person to be bound by a
confidentiality agreement; provided further, that the foregoing investigation
shall be coordinated on behalf of such persons by one representative designated
by and on behalf of such persons and any such confidential information shall be
available from such representative to such persons so long as any person agrees
to be bound by such confidentiality agreement;

         (viii)  if requested by the Initial Purchasers and, in the case of a
Shelf Registration Statement, any Holders of securities covered thereby, in
connection with such exchange or sale, promptly include in any Registration
Statement or Prospectus, pursuant to a supplement or post-effective amendment if
necessary, such information as such Persons may reasonably request to have
included therein, including, without limitation, information relating to the
"Plan of Distribution" of the Transfer Restricted Securities; and make all
required filings of such Prospectus supplement or post-effective amendment as
soon as practicable after the Company is notified of the matters to be included
in such Prospectus supplement or post-effective amendment;

                                       15
<PAGE>

          (ix) furnish to the Initial Purchasers and, in the case of a Shelf
Registration Statement, each Holder of securities covered thereby, in connection
with such exchange or sale, without charge, at least one copy of the
Registration Statement, as first filed with the Commission, and of each
amendment thereto, including all documents incorporated by reference therein and
all exhibits (including exhibits incorporated therein by reference);

          (x)  deliver to each Holder without charge, as many copies of the
 Prospectus (including each preliminary prospectus) and any amendment or
 supplement thereto as such Persons reasonably may request; the Company and the
 Guarantors hereby consent to the use (in accordance with law) of the Prospectus
 and any amendment or supplement thereto by each selling Holder in connection
 with the offering and the sale of the Transfer Restricted Securities covered by
 the Prospectus or any amendment or supplement thereto;

          (xi) in the case of a Shelf Registration Statement, enter into such
 agreements (including underwriting agreements) and, in the case of any
 Registration Statement contemplated by this Agreement, make such
 representations and warranties and take all such other actions in connection
 therewith in order to expedite or facilitate the disposition of the Transfer
 Restricted Securities pursuant to any applicable Registration Statement
 contemplated by this Agreement as may be reasonably requested by any Initial
 Purchaser or, in the case of a Shelf Registration Statement, the Holders of a
 majority in aggregate principal amount of the Transfer Restricted Securities
 covered thereby (the "Majority Holders") in connection with any sale or resale
 pursuant to any applicable Registration Statement. In such connection, the
 Company shall:

               (A)  upon request of the Majority Holders (in the case of a
          Shelf Registration Statement) or any Initial Purchaser (in the case of
          an Exchange Offer), furnish (or in the case of Sections WGWW) and
          6W(xiKW), use its best efforts to cause to be furnished) to each
          Holder upon Consummation of the Exchange Offer or upon the
          effectiveness of the Shelf Registration Statement, as the case may be:

                    (1)  a certificate, dated such date, signed on behalf of the
               Company and each Guarantor by (x) the President or any Vice
               President and (y) a principal financial or accounting officer of
               the Company and the Guarantor, confirming, as of the date
               thereof, the matters set forth in

                                       16
<PAGE>

               Sections 6(d), 9(a) and 9(b) of the Purchase Agreement and such
               other similar matters as may be reasonably requested;

                    (2)  an opinion, dated the date of Consummation of the
               Exchange Offer or the date of effectiveness of the Shelf
               Registration Statement, as the case may be, of counsel for the
               Company and the Guarantors covering matters similar to those set
               forth in paragraphs (e), (f), (g) and (h) of Section 9 of the
               Purchase Agreement and such other matter as may be reasonably
               requested, and in any event including a statement to the effect
               that such counsel has participated in conferences with officers
               and other representatives of the Company and the Guarantors,
               representatives of the independent public accountants for the
               Company and the Guarantors and have considered the matters
               required to be stated therein and the statements contained
               therein, although such counsel has not independently verified the
               accuracy, completeness or fairness of such statements; and that
               such counsel advises that, on the basis of the foregoing (relying
               as to materiality to the extent such counsel deems appropriate
               upon the statements of officers and other representatives of the
               Company and the Guarantors and without independent check or
               verification), no facts came to such counsel's attention that
               caused such counsel to believe that the applicable Registration
               Statement, at the time such Registration Statement or any post-
               effective amendment thereto became effective and, in the case of
               the Exchange Offer Registration Statement, as of the date of
               Consummation of the Exchange Offer, contained an untrue statement
               of a material fact or omitted to state a material fact required
               to be stated therein or necessary to make the statements therein
               not misleading, or that the Prospectus contained in such
               Registration Statement as of its date and, in the case of the
               opinion dated the date of Consummation of the Exchange Offer, as
               of the date of Consummation, contained an untrue statement of a
               material fact or omitted to state a material fact necessary in
               order to make the statements therein, in the light of the
               circumstances under which they were made, not misleading. Without
               limiting the foregoing, such counsel may state further that such
               counsel assumes no responsibility for, and has not indepen-
               dently verified, the accuracy, completeness or fairness of the
               financial statements, notes and schedules and other

                                       17
<PAGE>

               financial data included in any Registration Statement
               contemplated by this Agreement or the related Prospectus; and

                    (3)  a customary comfort letter, dated the date of
               Consummation of the Exchange Offer, or as of the date of
               effectiveness of the Shelf Registration Statement, as the case
               may be, from the Company's independent accountants, in the
               customary form and covering matters of the type customarily
               covered in comfort letters to underwriters in connection with
               underwritten offerings, and affirming the matters set forth in
               the comfort letters delivered pursuant to Section 9(j) of the
               Purchase Agreement; and

               (B)  deliver such other documents and certificates as may be
          reasonably requested by any of the Initial Purchasers or, in the case
          of any Shelf Registration Statement, the Majority Holders, to evidence
          compliance with the matters covered in Section 6(c)(xi)(A) above and
          with any customary conditions contained in any agreement entered into
          by the Company and the Guarantors pursuant to this Section 6(c)(xi);

          (xii)  prior to any public offering of Transfer Restricted Securities,
     cooperate with the Holders named in the applicable Registration Statement
     (or any prospectus supplement thereto) and their counsel in connection with
     the registration and qualification of the Transfer Restricted Securities
     under the securities or Blue Sky laws of such jurisdictions as any such
     Holders may request and do any and all other acts or things necessary or
     advisable to enable the disposition in such jurisdictions of the Transfer
     Restricted Securities covered by the applicable Registration Statement;
     provided, however, that neither the Company nor any Guarantor shall be
     required to register or qualify as a foreign corporation where it is not
     now so qualified or to take any action that would subject it to the service
     of process in suits or to taxation, other than as to matters and
     transactions relating to the Registration Statement, in any jurisdiction
     where it is not now so subject;

          (xiii) in connection with any sale of Transfer Restricted Securities
     that will result in such securities no longer being Transfer Restricted
     Securities, cooperate with the Holders to facilitate the timely preparation
     and delivery of certificates representing Transfer Restricted Securities to
     be sold and not bearing any restrictive legends; and, subject to the
     provisions of the Indenture regarding global securities, to register such
     Transfer Restricted Securities in such denominations and such names as

                                       18
<PAGE>

     the selling Holders may request at least two Business Days prior to such
     sale of Transfer Restricted Securities;

          (xiv)   use their respective best efforts to cause the disposition of
     the Transfer Restricted Securities covered by the Registration Statement to
     be registered with or approved by such other governmental agencies or
     authorities as may be necessary to enable the seller or sellers thereof to
     consummate the disposition of such Transfer Restricted Securities, subject
     to the proviso contained in Section 6(c)(xii) above;

          (xv)    provide a CUSIP number for all Transfer Restricted Securities
     not later than the effective date of a Registration Statement covering such
     Transfer Restricted Securities and provide the Trustee with printed
     certificates for the Transfer Restricted Securities which are in a form
     eligible for deposit with the Depository Trust Company;

          (xvi)   otherwise use their respective best efforts to comply with all
     applicable rules and regulations of the Commission, and make generally
     available to its security holders with regard to any applicable
     Registration Statement, as soon as practicable, a consolidated earnings
     statement meeting the requirements of Rule 158 (which need not be audited)
     covering a twelve-month period beginning after the effective date of the
     Registration Statement (as such term is defined in paragraph (c) of Rule
     158 under the Act);

          (xvii)  cause the Indenture to be qualified under the TIA not later
     than the effective date of the first Registration Statement required by
     this Agreement and, in connection therewith, cooperate with the Trustee and
     the Holders to effect such changes to the Indenture as may be required for
     such Indenture to be so qualified in accordance with the terms of the TIA;
     and execute and use its best efforts to cause the Trustee to execute, all
     documents that may be required to effect such changes and all other forms
     and documents required to be riled with the Commission to enable such
     Indenture to be so qualified in a timely manner; and

          (xviii) provide promptly to each Holder, upon request, each document
     filed with the Commission pursuant to the requirements of Section 13 or
     Section 15(d) of the Exchange Act.

     (d)  Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of the notice referred to in
Section 4(c) or Section 6(c)(iii)(C) or any notice from the Company of the
existence of any fact of the kind described in Section 6(c)(iii)(D) hereof (in
each case, a "Suspension Notice"), such Holder will forthwith discontinue
disposition of

                                       19
<PAGE>

Restricted Securities pursuant to the applicable Registration Statement until
(i) such Holder has received copies of the supplemented or amended Prospectus
contemplated by Section 6(c)(iv) hereof, or (ii) such Holder is advised in
writing by the Company that the use of the Prospectus may be resumed, and has
received copies of any additional or supplemental filings that are incorporated
by reference in the Prospectus (in each case, the "Recommencement Date"). Each
Holder receiving a Suspension Notice hereby agrees that it will either (i)
destroy any Prospectuses, other than permanent file copies, then in such
Holder's possession which have been replaced by the Company with more recently
dated Prospectuses or (ii) deliver to the Company (at the Company's expense) all
copies, other than permanent file copies, then in such Holder's possession of
the Prospectus covering such Transfer Restricted Securities that was current at
the time of receipt of the Suspension Notice. The time period regarding the
effectiveness of such Registration Statement set forth in Section 3 or 4 hereof,
as applicable, shall be extended by a number of days equal to the number of days
in the period from and including the date of delivery of the Suspension Notice
to the date of delivery of the Recommencement Date.

     No holder may participate in any underwritten registration under the
Agreement unless such Holder (a) agrees to sell such Holder's Transfer
Restricted Securities on the basis provided in any underwriting arrangements
approved by the Persons entitled under this Agreement to approve such
arrangements and (b) completes and executes all reasonable questionnaires,
powers of attorneys, indemnities, underwriting agreements, lock-up letters and
other documents required under the terms of such underwriting arrangements.

     Section 7. Registration Expenses.

     (a)  All expenses incident to the Company's and the Guarantors' performance
of or compliance with this Agreement will be borne by the Company, regardless of
whether a Registration Statement becomes effective, including without
limitation: (i) all registration and filing fees and expenses; (ii) all fees and
expenses of compliance with federal securities and state Blue Sky or securities
laws; (iii) all expenses of printing (including printing certificates for the
Exchange Notes to be issued in the Exchange Offer and printing of Prospectuses),
messenger and delivery services and telephone; (iv) all fees and disbursements
of counsel for the Company, the Guarantors and, in accordance with Section 7(b)
below, the Holders of Transfer Restricted Securities; (v) all application and

securities exchange or automated quotation system pursuant to the requirements
hereof; and (vi) all fees and disbursements of independent certified public
accountants of the Company and the Guarantors (including the expenses of any
special audit and comfort letters required by or incident to such performance).

                                       20
<PAGE>

     The Company will, in any event, bear its and the Guarantors' internal
expenses (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expenses of
any annual audit and the fees and expenses of any Person, including special
experts, retained by the Company or any Guarantor.

     (b)  In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Company and the Guarantors
will reimburse the Initial Purchasers and the Holders of Transfer Restricted
Securities who are tendering Initial Notes in the Exchange Offer and/or selling
or reselling Initial Notes or Exchange Notes pursuant to the "Plan of
Distribution" contained in the Exchange Offer Registration Statement or the
Shelf Registration Statement, as applicable, for the reasonable fees and
disbursements of not more than one counsel, who shall be Davis Polk & Wardwell,
unless another firm shall be chosen by the Holders of a majority in principal
amount of the Transfer Restricted Securities for whose benefit such Registration
Statement is being prepared.

     Section 8. Indemnification.

     (a)  The Company and each of the Guarantors agree, jointly and severally,
to indemnify and hold harmless each Holder, its directors, officers and each
Person, if any, who controls such Holder (within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act), from and against any and all losses,
claims, damages, liabilities, judgments, (including without limitation, any
legal or other expenses incurred in connection with investigating or defending
any matter, including any action that could give rise to any such losses,
claims, damages, liabilities or judgments) caused by any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement, preliminary prospectus or Prospectus (or any amendment or supplement
thereto) provided by the Company to any Holder or any prospective purchaser of
Exchange Notes or registered Initial Notes, or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by an untrue
statement or omission or alleged untrue statement or omission that is based upon
information relating to any of the Holders furnished in writing to the Company
by any of the Holders provided, however, that the foregoing indemnity agreement
with respect to the preliminary prospectus shall not inure to the benefit of any
Holder who failed to deliver the Prospectus, as then amended or supplemented (so
long as the Prospectus and any such amendment or supplement was provided by the
Company to the Holders in the requisite quantity and on a timely basis to permit
proper delivery) to the person asserting any losses, claims, damages,
liabilities or

                                       21
<PAGE>

judgments caused by any untrue statement or alleged untrue statement of a
material fact contained in the preliminary prospectus, or caused by any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, if such
material misstatement or omission or alleged material misstatement or omission
was cured in the Prospectus, as so amended or supplemented.

     (b)  Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, to indemnify and hold harmless the Company and the Guarantors, and
their respective directors and officers, and each person, if any, who controls
(within the meaning of Section 15 of the Act or Section 20 of the Exchange Act)
the Company or the Guarantors to the same extent as the foregoing indemnity from
the Company and the Guarantors set forth in Section S(a) above, but only with
reference to information relating to such Holder furnished in writing to the
Company by such Holder expressly for use in any Registration Statement,
preliminary prospectus or Prospectus (or any amendment or supplement thereto).
In no event shall any Holder, its directors, officers or any Person who controls
such Holder be liable or responsible for any amount in excess of the total
amount received by such Holder with respect to its sale of Transfer Restricted
Securities pursuant to a Registration Statement exceeds the amount of any
damages that such Holder, its directors, officers or any Person who controls
such Holder has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.

     (c)  In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or S(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying person") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections S(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party,

                                       22
<PAGE>

shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party). In any such case, the indemnifying party shall not, in
connection with any one action or separate but substantially similar or related
actions 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 (in addition to any local counsel) for all indemnified parties
and all such fees and expenses shall be reimbursed as they are incurred. Such
firm shall be designated in writing by a majority of the Holders, in the case of
the parties indemnified pursuant to Section 8(a), and by the Company and the
Guarantors, in the case of parties indemnified pursuant to Section 8(b). The
indemnifying party shall indemnify and hold harmless the indemnified party from
and against any and all losses, claims, damages, liabilities and judgments by
reason of any settlement of any action (i) effected with its written consent or
(ii) effected without its written consent if the settlement is entered into more
than sixty days after the indemnifying party shall have received a request from
the indemnified party for reimbursement for the fees and expenses of counsel (in
any case where such fees and expenses are at the expense of the indemnifying
party) and more than twenty days after the indemnifying party shall have
received notice of the proposed settlement and, prior to the date of such
settlement, the indemnifying party shall have failed to comply with such
reimbursement request. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement or compromise of, or
consent to the entry of judgment with respect to, any pending or threatened
action in respect of which the indemnified party is or could have been a party
and indemnity or contribution may be or could have been sought hereunder by the
indemnified party, unless such settlement, compromise or judgment (i) includes
an unconditional release of the indemnified party from all liability on claims
that are or could have been the subject matter of such action 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 the indemnified party.

          (d)  To the extent that the indemnification provided for in this
Section 8 is unavailable to an indemnified party in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or judgments in such proportion as
is appropriate to reflect the relative fault of the Company and the Guarantors,
on the one hand, and of the Holder, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative fault of the Company and the Guarantors, on the one
hand, and of the Holder, on the other hand, shall be

                                       23
<PAGE>

determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or the
Guarantors, on the one hand, or by the Holder, on the other hand, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Company, the Guarantors and each Holder agree that it would not be just
and equitable if contribution pursuant to this Section 8(d) 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 which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses incurred by such indemnified party in
connection with investigating or defending any matter, including any action,
that could have given rise to such losses, claims, damages, liabilities or
judgments. Notwithstanding the provisions of this Section 8, no Holder, its
directors, its officers or any Person, if any, who controls such Holder shall be
required to contribute, in the aggregate, any amount in excess of the amount by
which the total received by such Holder with respect to the sale of Transfer
Restricted Securities pursuant to a Registration Statement exceeds the amount of
any damages which 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 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 Transfer Restricted Securities held by each
Holder hereunder and not joint.

     Section 9. Rule 144A and Rule 144.

     The Company and each Guarantor agrees with each Holder, for so long as any
Transfer Restricted Securities remain outstanding and during any period in which
the Company or any Guarantor (i) is not subject to Section 13 or 15(d) of the
Exchange Act, to make available, upon request of any Holder, to such Holder or
beneficial owner of Transfer Restricted Securities in connection with any sale
thereof and any prospective purchaser of such Transfer Restricted Securities
designated by such Holder or beneficial owner, the information required by Rule
144A(d)(4) under the Act in order to permit resales of such Transfer Restricted
Securities pursuant to Rule 144A, and (ii) is subject to Section 13 or 15 (d) of
the Exchange Act, to make all filings required thereby in a timely manner in
order to permit resales of such Transfer Restricted Securities pursuant to Rule
144.

         Section 10. Miscellaneous.

         (a) Remedies. The Company and the Guarantors acknowledge and agree that
any failure by the Company and/or any Guarantor to comply with their respective
obligations under Sections 3 and 4 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 Sections 3 and 4 hereof. The
Company and the Guarantors further agree to waive the defense in any action for
specific performance that a remedy at law would be adequate.

         (b) No Inconsistent Agreements. Neither the Company nor any Guarantor
will, on or after the date of this Agreement, enter into any agreement with
respect to its securities that is inconsistent with the rights granted to the
Holders in this Agreement or otherwise conflicts with the provisions hereof.
Neither the Company nor any Guarantor has previously entered into any agreement
which remains in effect granting any registration rights with respect to its
securities to any Person. The rights granted to the Holders hereunder do not in
any way conflict with and are not inconsistent with the rights granted to the
holders of the Company's and the Guarantors' securities under any agreement in
effect on the date hereof.

         (c) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this clause 10(c)(i), the Company has obtained the written consent of
Holders of all outstanding Transfer Restricted Securities and (ii) in the case
of all other provisions hereof, the Company has obtained the written consent of
Holders of a majority of the outstanding principal amount of Transfer Restricted
Securities (excluding Transfer Restricted Securities held by the Company or its
Affiliates). Notwithstanding the foregoing, a waiver or consent to departure
from the provisions hereof that relates exclusively to the rights of Holders
whose Transfer Restricted Securities are being tendered pursuant to the Exchange
Offer, and that does not affect directly or indirectly the rights of other
Holders whose Transfer Restricted Securities are not being tendered pursuant to
such Exchange Offer, may be given by the Holders of a majority of the
outstanding principal amount of Transfer Restricted Securities subject to such
Exchange Offer.

         (d) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company and the
Guarantors, on the one hand, and the Initial Purchasers, on the other hand, and

                                       25
<PAGE>

 shall have the right to enforce such agreements directly to the extent they may
 deem such enforcement necessary or advisable to protect its rights or the
 rights of Holders hereunder.

         (e) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail
(registered or certified, return receipt requested), telex, telecopier, or air
courier guaranteeing overnight delivery:

         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 receipt
acknowledged, if telecopied; and on the next business day, if timely delivered

         Copies of all such notices, demands or other communications shall be
concurrently delivered by the Person giving the same to the Trustee at the

         (f) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors and assigns 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 Transfer Restricted Securities in
violation of the

                                       26
<PAGE>

terms hereof or of the Purchase Agreement or the Indenture. If any transferee of
any Holder shall acquire Transfer Restricted Securities in any manner, whether
by operation of law or otherwise, such Transfer Restricted Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Transfer Restricted 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, including the restrictions on resale set forth in this Agreement
and, if applicable, the Purchase Agreement, and such Person shall be entitled to
receive the benefits hereof.

         (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.

         (i)  Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE
CONFLICT OF LAW RULES THEREOF.

         (j)  Severability. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein shall not be affected or impaired thereby.

         (k)  Entire Agreement. This Agreement is intended by the parties as a
final expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
with respect to the registration rights granted with respect to the Transfer
Restricted Securities. This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

                                       27

be.

     Section 1.06. Compliance Certificates and Opinions. Upon any application or
request by the Company or by any other obligor upon the Notes to the Trustee to
take any action under any provision of this Indenture, the Company or such other
obligor upon the Notes, as the case may be, shall furnish to the Trustee such

other requirements set forth in this Indenture. Notwithstanding the foregoing,
in the case of any such request or application as to which the furnishing of any
Officer's Certificate or Opinion of Counsel is specifically required by any

<PAGE>

     (d) a statement as to whether, in the opinion of such individual, such
condition or covenant has been complied with.

     Section 1.07. Form of Documents Delivered to Trustee. In any case where
several matters are required to be certified by, or covered by an opinion of,
any specified Person, it is not necessary that all such matters be certified by,
or covered by the opinion of, only one such Person, or that they be so certified
or covered by only one document, but one such Person may certify or give an
opinion with respect to some matters and one or more other such Persons as to
other matters, and any such Person may certify or give an opinion as to such
matters in one or several documents.

     Any certificate or opinion of an Officer may be based, insofar as it
relates to legal matters, upon a certificate or opinion of, or representations
by, counsel, unless such Officer knows that the certificate or opinion or
representations with respect to the matters upon which his certificate or
opinion is based are erroneous. Any such certificate or opinion of counsel may
be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an Officer or Officers to the effect that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows that the certificate or opinion or
representations with respect to such matters are erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

authorization, direction, notice, consent, waiver or other action provided by

in person or by agent duly appointed in writing; and, except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee, and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"Act" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 7.01)
conclusive in favor of the Trustee, the Company and any other obligor upon the
Notes, if made in the manner provided in this Section 1.08.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by
the certificate of any notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
an officer of a corporation or a member of a partnership or other entity, on
behalf of such corporation or partnership or other entity, such certificate or
affidavit shall also constitute sufficient proof of such Person's authority. The
fact and date of the execution

                                       32
<PAGE>

of any such instrument or writing, or the authority of the person executing the
same, may also be proved in any other manner that the Trustee deems sufficient.

     (c) The ownership of Notes shall be proved by the Register.

     (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Note shall bind the Holder of every Note
issued upon the transfer thereof or in exchange therefor or in lieu thereof, in
respect of anything done or suffered to be done by the Trustee, the Company or
any other obligor on the Notes in reliance thereon, whether or not notation of
such action is made upon such Note.

     (e) (i) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or
making of any notice, declaration, request or direction referred to in Section
1.08(e)(ii). If any record date is set pursuant to this paragraph, the Holders
of Outstanding Notes on such record date (or their duly designated proxies), and
no other Holders, shall be entitled to take the relevant action, whether or not
such Persons remain Holders after such record date; provided that no such action
shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Notes on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be canceled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Notes on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder in the manner set forth in Section 1.10.

     (ii) The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Notes entitled to join in the giving or
making of (w) any Notice of Default, (x) any declaration of acceleration
referred to in Section 6.02, (y) any request to institute proceedings referred
to in Section 6.06(b) or (z) any direction referred to in Section 6.05, in each
case with respect to Notes. If any record date is set pursuant to this
paragraph, the Holders of Outstanding Notes on such record date, and no other
Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date;
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Notes on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be canceled and of no effect), and

                                       33
<PAGE>

nothing in this paragraph shall be construed to render ineffective any action
taken by Holders of the requisite principal amount of Outstanding Notes on the
date such action is taken. Promptly after any record date is set pursuant to
this paragraph, the Trustee, at the expense of the Company, shall cause notice
of such record date, the proposed action by Holders and the applicable
Expiration Date to be given to the Company in writing and to each Holder in the
manner set forth in Section 1.10.

     (iii) With respect to any record date set pursuant to this Section 1.08,
the party hereto that sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the Company or the
Trustee, whichever such party is not setting a record date pursuant to this
Section 1.08(e) in writing, and to each Holder in the manner set forth in
Section 1.10, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto that set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

     (iv)  Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Note may do so with regard to
all or any part of the principal amount of such Note or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

     Section 1.09. Notices, Etc., to Trustee and Company. Any request, demand,
authorization, direction, notice, consent, waiver or Act of Holders or other
document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

     Section 1.10. Notices to Holders; Waivers. Where this Indenture provides
for notice to Holders of any event, such notice shall be deemed to have been
given upon the mailing by first class mail, postage prepaid, of such notices to
Holders at their registered

<PAGE>

addresses as recorded in the Register, not later than the latest date, and not
earlier than the earliest date, prescribed herein for the giving of such notice.
In any case where notice to Holders is given by mail, neither the failure to
mail such notice, nor any defect in any notice so mailed, to any particular
Holder shall affect the sufficiency of such notice with respect to other
Holders.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

     In case, by reason of the suspension of regular mail service, or by reason
of any other cause, it shall be impossible to mail notice of any event as
required by any provision of this Indenture, then such notification as shall be
made with the approval of the Trustee (such approval not to be unreasonably
withheld) shall constitute a sufficient notification for every purpose
hereunder.

     Section 1.11. Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

     Section 1.12. Successors and Assigns. All covenants and agreements in this
Indenture by the Company shall bind its respective successors and assigns,
whether so expressed or not.

     Section 1.13. Separability Clause. In case any provision in this Indenture
or in the Notes shall be invalid, illegal or unenforceable, the validity,
legality and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

     Section 1.14. Benefits of Indenture. Nothing in this Indenture or in the
Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, any Paying Agent and the Holders, any
benefit or any legal or equitable right, remedy or claim under this Indenture.

     Section 1.15. Governing Law. THIS INDENTURE, THE NOTES AND THE SUBSIDIARY
GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICT OF
LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD
BE REQUIRED THEREBY. TO THE EXTENT PERMITTED BY LAW, THE TRUSTEE, THE COMPANY,
THE SUBSIDIARY GUARANTORS, ANY OTHER OBLIGORS IN RESPECT OF THE NOTES AND (BY
THEIR ACCEPTANCE OF THE NOTES) THE HOLDERS, AGREE TO SUBMIT TO THE NON-EXCLUSIVE
JURISDICTION OF ANY UNITED STATES FEDERAL OR STATE COURT LOCATED IN THE BOROUGH

     Section 1.16. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date or Stated Maturity of any Note shall not be a Business Day, then

need not be made on such date, but may be made on the next succeeding Business

or the Subsidiary Guarantors under the Notes, the Subsidiary Guarantees, the
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of Notes by accepting a Note waives
and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

herein set forth in full.

initially limited to $393,000,000, but may be increased, subject to compliance
with the covenants contained in Article 4 below and the conditions set forth in
Section 3.03, and except as may be limited by applicable law. The Initial Notes

and delivery of such Notes or did not hold such office at the date of such
Notes.

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Notes executed by the Company to the Trustee
for authentication; and the Trustee shall authenticate and deliver (i) Initial
Notes for original issue in the aggregate principal amount not to exceed
$393,000,000 and (ii) Additional Notes from time to time for original issue in
aggregate principal amounts specified by the Company and (iii) Exchange Notes
from time to time for issue in exchange for a like principal amount of Initial
Notes or Initial Additional Notes, in each case specified in clauses (i) through
(iii) above, upon a written order of the Company in the form of an Officer's
Certificate (an "Authentication Order"), and in the case of clause (ii), upon
receipt by the Trustee of an Opinion of Counsel confirming that the Holders of
the Outstanding Notes will be subject to federal income tax in the same amounts,
in the same manner and at the same times as would have been the case if such
Additional Notes were not issued. Such Officer's Certificates shall specify the
amount of Notes to be authenticated and the date on which the Notes are to be
authenticated, whether the Notes are to be Initial Notes, Additional Notes or
Exchange Notes, that, in the case of Additional Notes, (x) the issuance of such
Notes does not contravene any provision of Article 4 of this Indenture and (y)
after giving effect to such issuance of Additional Notes and the application of
the use of proceeds therefrom, the aggregate principal amount of Notes
outstanding does not exceed the amount permitted to be equally and ratably
secured under the Existing Credit Facility without causing a default thereunder,
whether the Notes are to be issued as one or more Global Notes or Physical
Notes, the

                                       42
<PAGE>

name or names of the Initial Holder or Holders and such other information as the
Company may include or the Trustee may reasonably request.

     All Notes shall be dated the date of their authentication.

     No Note shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Note a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Note shall be
conclusive evidence, and the only evidence, that such Note has been duly
authenticated and delivered hereunder.

     Section 3.04. Temporary Notes. Until definitive Notes are ready for
delivery, the Company may prepare and upon receipt of an Authentication Order
the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company considers appropriate for temporary Notes. If temporary Notes are
issued, the Company will cause definitive Notes to be prepared without
unreasonable delay. After the preparation of definitive Notes, the temporary
Notes shall be exchangeable for definitive Notes upon surrender of the temporary
Notes at the office or agency of the Company in a Place of Payment, without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Notes, the Company shall execute and upon receipt of an Authentication
Order the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Notes of authorized denominations. Until so
exchanged the temporary Notes shall in all respects be entitled to the same
benefits under this Indenture as definitive Notes of the same series and tenor.

     Section 3.05. Registration, Registration of Transfer and Exchange. The
Company shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the "Register") in which, subject to such reasonable regulations
as it may prescribe, the Company shall provide for the registration of Notes and
of transfers of Notes. The Trustee is hereby appointed "Registrar" for the
purpose of registering Notes and transfers of Notes as herein provided.

     Upon surrender for transfer of any Note at the office or agency of the
Company in a Place of Payment, in compliance with all applicable requirements of
this Indenture and applicable law, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Notes, of any authorized denominations and of a
like aggregate principal amount.

     At the option of the Holder, Notes may be exchanged for other Notes, of
any authorized denominations and of a like tenor and aggregate principal amount,
upon surrender of the Notes to be exchanged at such office or agency. Whenever
any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Holder making the
exchange is entitled to receive; provided that no exchange of Initial Notes or
Initial Additional Notes for Exchange Notes shall occur until an Exchange Offer
Registration Statement shall have

                                       43
<PAGE>

been declared effective by the SEC and the Trustee shall have received an
Officer's Certificate confirming that the Exchange Offer Registration Statement
has been declared effective by the SEC and an exchange offer thereunder has been
consummated. The Initial Notes or Additional Notes to be exchanged for the
Exchange Notes shall be canceled by the Trustee.

     All Notes issued upon any registration of transfer or exchange of Notes
shall be the valid obligations of the Company, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

     Every Note presented or surrendered for registration of transfer or
exchange shall (if so required by the Company or the Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Registrar duly executed, by the Holder
thereof or such Holder's attorney duly authorized in writing.

     No service charge shall be made for any registration of transfer or
exchange or redemption of Notes, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Notes under this
Section 3.05.

     Section 3.06. Mutilated, Destroyed, Lost and Stolen Notes. If (a) any
mutilated Note is surrendered to the Trustee, or the Company and the Trustee
receive evidence to their satisfaction of the destruction, loss or theft of any
Note, and (b) there is delivered to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Company or the Trustee that such Note has been acquired
by a bona fide purchaser, the Company shall execute and upon receipt of an
Authentication Order the Trustee shall authenticate and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Note, a new Note of
like tenor and principal amount, bearing a number not contemporaneously
Outstanding.

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and payable, the Company in its discretion may, instead of
issuing a new Note, pay such Note.

     Upon the issuance of any new Note under this Section 3.06, the Company may
require the payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Note issued pursuant to this Section 3.06 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and ratably with
any and all other Notes duly issued hereunder.

                                       44
<PAGE>

     The provisions of this Section 3.06 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Notes.

     Section 3.07. Payment of Interest Rights Preserved. Interest and Liquidated
Damages on any Note that is payable, and is punctually paid or duly provided
for, on any Interest Payment Date shall be paid to the Person in whose name that
Note (or one or more Predecessor Notes) is registered at the close of business
on the Regular Record Date for such interest and Liquidated Damages specified in
Section 3.01.

     Any interest and Liquidated Damages on any Note that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having been
such Holder; and such Defaulted Interest shall be paid by the Company, as
provided in 3.07(a) or 3.07(b) below:

     (a)  The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Notes (or their respective Predecessor Notes) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Note and the date of the proposed payment, and at
the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements reasonably satisfactory to the Trustee for
such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as provided in this Section 3.07(a). Thereupon the Trustee
shall fix a Special Record Date for the payment of such Defaulted Interest which
shall be not more than 15 nor less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest,
the amount thereof and the Special Record Date and payment date therefor to be
mailed, first class postage prepaid, to each Holder at such Holder's address as
it appears in the Register, not less than 10 days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special
Record Date therefor having been so mailed, such Defaulted Interest shall be
paid to the Persons in whose names the Notes (or their respective Predecessor
Notes) are registered on such Special Record Date and shall no longer be payable
pursuant to the following 3.07(b).

     (b)  The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Notes may be listed, and upon such notice as may be required by
such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause (b), such payment shall be deemed
practicable by the Trustee.

     Subject to the foregoing provisions of this Section 3.07, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any

                                       45
<PAGE>

other Note shall carry the rights to interest (including any Liquidated Damages)
accrued and unpaid, and to accrue, that were carried by such other Note.

     Section 3.08. Persons Deemed Owners. Prior to due presentment of a Note for
registration of transfer, the Company, the Trustee and any agent of the Company
or the Trustee may treat the Person in whose name such Note is registered as the
owner of such Note for the purpose of receiving payment of principal of (and
premium, if any, on) and (subject to Section 3.07) interest and Liquidated
Damages, if any, on such Note and for all other purposes whatsoever, whether or
not such Note be overdue, and none of the Company, the Subsidiary Guarantors,
the Trustee or any agent of the Company, the Subsidiary Guarantors or the
Trustee shall be affected by notice to the contrary.

     Section 3.09. Cancellation. All Notes surrendered for payment, redemption,
registration of transfer or exchange shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and, if not already canceled,
shall be promptly canceled by it. The Company may at any time deliver to the
Trustee for cancellation any Notes previously authenticated and delivered
hereunder that the Company may have acquired in any manner whatsoever, and all
Notes so delivered shall be promptly canceled by the Trustee. No Notes shall be
authenticated in lieu of or in exchange for any Notes canceled as provided in
this Section 3.09, except as expressly permitted by this Indenture. All canceled
Notes held by the Trustee shall be disposed of in accordance with the Trustee's
customary procedures.

     Section 3.10. Computation of Interest. Interest on the Notes shall be
computed on the basis of a 360-day year of twelve 30-day months.

     Section 3.11. Payment of Liquidated Damages. (a) Under certain
circumstances the Company will be obligated to pay certain Liquidated Damages to
the Holders of certain Initial Notes, as more particularly set forth in such
Initial Notes.

     (b) Under certain circumstances the Company may be obligated to pay certain
Liquidated Damages to the Holders of certain Initial Additional Notes, as may be
more particularly set forth in such Initial Additional Notes.

     Section 3.12. CUSIP Numbers. The Company in issuing the Notes may use
"CUSIP" or "CINS" numbers (if then generally in use) in addition to serial
numbers, and, if so, the Trustee shall use such "CUSIP" or "CINS" numbers in
addition to serial numbers in notices of redemption, repurchase or other notices
to Holders as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such "CUSIP" or "CINS"
numbers either as printed on the Notes or as contained in any notice of a
redemption or repurchase and that reliance may be placed only on the serial or
other identification numbers printed on the Notes, and any such redemption or
repurchase shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee of any change in the "CUSIP" or
"CINS" numbers.

     Section 3.13. Book-entry Provisions for Global Notes.

     (a) Each Global Note initially shall (i) be registered in the name of the
Depositary for such Global Notes or the nominee of such Depositary, (ii) be
delivered to the Trustee as custodian for such Depositary and (iii) to the
extent relevant thereto, bear legends as set forth in Section 2.03. None of the
Company or the Subsidiary Guarantors, nor any of their agents shall have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of beneficial ownership interests of, a Global Note, or
for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

     Members of, or participants in, the Depositary ("Agent Members") shall have
no rights under this Indenture with respect to any Global Note, and the
Depositary may be treated by the Company, the Subsidiary Guarantors, the Trustee
and any agent of the Company, the Subsidiary Guarantors or the Trustee as the
absolute owner of such Global Note for all purposes whatsoever. Notwithstanding
the foregoing, nothing herein shall prevent the Company, the Subsidiary
Guarantors, the Trustee or any agent of the Company, the Subsidiary Guarantors
or the Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a beneficial owner of any Note. The registered Holder
of a Global Note may grant proxies and otherwise authorize any person, including
Agent Members and persons that may hold interests through Agent Members, to take
any action which a Holder is entitled to take under this Indenture or the Notes.

     (b) Interests of beneficial owners in a Global Note may be transferred in
accordance with the applicable rules and procedures of the Depositary and the
provisions of Section 3.14. Transfers of a Global Note shall be limited to
transfers of such Global Note in whole, but not in part, to the Depositary, its
successors or their respective nominees, except (i) as required in connection
with transfers of interests therein pursuant to Section 3.14(b) or 3.14(g) or as
may be required by the Company or the Trustee in connection with transfers
pursuant to Section 3.14(i), and (ii) that U.S. Physical Notes or, subject to
Section 3.14(h), Offshore Physical Notes shall be transferred to all beneficial
owners in exchange for their beneficial interests in the U.S. Global Note or the
Offshore Global Note, respectively, in the event that (A) the Depositary
notifies the Company that it is unwilling or unable to continue as Depositary
for the applicable Global Note and a successor depositary is not appointed by
the Company within 90 days or (B) an Event of Default has occurred and is
continuing and the Registrar has received a request from the Depositary. In
addition, beneficial interests in a Global Note may be exchanged for Physical
Notes upon request but only upon at least 20 days' prior written notice given to
the Trustee by or on behalf of the Depository in accordance with customary
procedures. In connection with any transfer or exchange of a portion of the
beneficial interest in any Global Note to beneficial owners for Physical Notes
pursuant to this Section 3.13(b), the Registrar shall record on its books and
records (and make a notation on the Global Note of) the date and a decrease in
the principal amount of such Global Note in an amount equal to the beneficial
interest in the Global Note being transferred, and the Company shall execute,
and the Trustee shall authenticate and deliver, one or more Physical Notes of
like tenor and principal amount of authorized

                                       47
<PAGE>

denominations. In connection with a transfer of an entire Global Note to
beneficial owners pursuant to this paragraph (b), the applicable Global Note
shall be deemed to be surrendered to the Trustee for cancellation, and the
Company shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in the applicable Global Note, an equal aggregate principal amount at
maturity of U.S. Physical Notes (in the case of the U.S. Global Note) or
Offshore Physical Notes (in the case of the Offshore Global Note), as the case
may be, of authorized denominations.

     (c) Any beneficial interest in one of the Global Notes that is transferred
to a person who takes delivery in the form of an interest in another Global Note
will, upon transfer, cease to be an interest in such Global Note and become an
interest in the other Global Note and, accordingly, will thereafter be subject
to all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Global Note for as long as it remains such an
interest.

     (d) The Company, the Subsidiary Guarantors, any other obligor upon the
Notes or the Trustee, in the discretion of any of them, may treat as the Act of
a Holder any instrument or writing of any Person that is identified by the
Depositary as the owner of a beneficial interest in the Global Note, provided
that the fact and date of the execution of such instrument or writing is proved
in accordance with Section 1.08(b).

     (e) Any U.S. Physical Note delivered in exchange for an interest in the
U.S. Global Note pursuant to paragraph (b) of this Section shall, except as
otherwise provided in Section 3.14, bear the Private Placement Legend.

     Section 3.14. Transfer Provisions. Unless and until (i) an Initial Note or
any Initial Additional Note is sold pursuant to an effective registration
statement, whether pursuant to the Registration Rights Agreement or otherwise,
(ii) an Initial Note or any Initial Additional Note is exchanged for an Exchange
Note in the Exchange Offer pursuant to an effective Registration Statement, or
(iii) the Resale Restriction Termination Date has occurred with respect to an
Initial Note or any Initial Additional Note and such Note is not then held by an
Affiliate of the Company, the following provisions shall apply with respect to
such Initial Note or Initial Additional Note:

     (a) General. The provisions of this Section 3.14 shall apply to all
transfers involving any Physical Note and any beneficial interest in any Global
Note. A Note that is a Restricted Security may not be transferred other than as
provided in this Section 3.14. A beneficial interest in a Global Note that is a
Restricted Security may not be exchanged for a beneficial interest in another
Global Note other than through a transfer in compliance with this Section 3.14.

     (b) Transfers to Non-QIB Institutional Accredited Investors. With respect
to the registration of any proposed transfer of a Note that is a Restricted
Security to any Institutional Accredited Investor that is not a QIB,

     Indenture (including Section 3.05 and Section 3.13); and

          (ii)  the proposed transferee has delivered to the Registrar a
     certificate substantially in the form of Exhibit E, and such transfer is in
     respect of an aggregate principal amount of Notes of not less than
     $100,000; and

          (iii) if the proposed transferor is or is acting through an Agent
     Member holding a beneficial interest in a Global Note, upon receipt by the
     Registrar of written instructions given in accordance with the Depositary's
     and the Registrar's procedures; and

     (II) the Registrar shall (x) reflect on its books and records (and make a
notation on the relevant Global Note of) the date and a decrease in the
principal amount of the relevant Global Note in an amount equal to the principal
amount of the beneficial interest in the relevant Global Note to be transferred
or (y) cancel the Physical Note so transferred, and the Registrar shall deliver
to the transferee one or more Physical Notes of like tenor and amount.

     Each of the Company and the Trustee may require additional opinions,
certifications or other evidence as may be reasonably required to confirm that
any such proposed transfer is being made in compliance with the Securities Act
and applicable state securities laws.

     (c)  Transfers to QIBs. With respect to the registration of any proposed
transfer of a Note that is a Restricted Security to a QIB,

     this Indenture (including Section 3.05 and Section 3.13); and

               (ii) the proposed transferor has checked the box provided for on
     the form of such Note stating, or has otherwise certified to the Company

     certification provided for on the form of such Note stating, or has
     otherwise certified to the Company and the Registrar in writing, that it is
     purchasing such Note for its own account or an account with respect to
     which it exercises sole investment discretion and that it and any such
     account is a QIB within the meaning of Rule 144A, and is aware that the
     sale to it is being made in reliance on Rule 144A and acknowledges that it
     has received such information regarding the Company as it has requested
     pursuant to Rule 144A or has determined not to request such information and
     that it is aware that the transferor is relying upon its foregoing
     representations in order to claim the exemption from registration provided
     by Rule 144A; and

                                       49
<PAGE>

          (iii) if the proposed transferor or transferee is or is acting through

     the form of Exhibit D hereto and will take delivery in the form of an

     (I) the Registrar shall register such transfer

          (A)  if it complies with all other requirements of this Indenture
     (including Section 3.05 and Section 3.13); and

          (B)  if such transfer is being made by a proposed transferor who has
     checked the box provided for on the form of such Note stating, or has
     otherwise certified to the Company and the Registrar in writing, that the
     sale has been made to the Company; and

          (C)  if the proposed transferor is or is acting through an Agent
     Member, upon receipt by the Registrar of written instructions given in
     accordance with the Depositary's and the Registrar's procedures; and

     (II) the Registrar shall (x) reflect on its books and records (and make a
notation on the relevant Global Note of) the date and a decrease in the
principal amount of such transferor Global Note in an amount equal to the
principal amount to be transferred or (y) cancel the Physical Note so
transferred, as the case may be and the Registrar shall deliver Physical Notes
to the Company in like tenor and amount.

     (h) Interests in the Offshore Global Note prior to the Offshore Note
Exchange Date. Notwithstanding anything to the contrary contained in this
Indenture, until the Offshore Note Exchange Date occurs and appropriate
certification substantially in the form of Exhibit C is made as provided in
Section 2.01, beneficial interests in the Offshore Global Note may be held only
in or through accounts maintained at the Depositary by Euroclear or Clearstream,
and no person shall be entitled to effect any transfer or exchange that would
result in any such interest being held otherwise than in or through such an
account, and no Physical Notes may be issued in exchange therefor.

     (i) Other Transfers. The Registrar shall effect and register, upon receipt
of a written request from the Company to do so, a transfer not otherwise
permitted by this Section 3.14, such registration to be done in accordance with
the otherwise applicable

                                       52
<PAGE>

provisions of this Section 3.14, upon the furnishing by the proposed transferor
or transferee of a written opinion of counsel (which opinion and counsel are
satisfactory to the Company and the Trustee) to the effect that, and such other
certifications or evidence as the Company may require to confirm that, the
proposed transfer is being made pursuant to an exemption from, or in a
transaction not subject to, the registration requirements of the Securities Act
and otherwise in compliance with applicable state securities laws.

     (j) Limitation on Issuance of Physical Notes. No Physical Note shall be
exchanged for a beneficial interest in any Global Note, except in accordance
with Section 3.13 and this Section 3.14.

     (k) Execution, Authentication and Delivery of Physical Notes. In any case
in which the Registrar is required to deliver a Physical Note to a transferee or
transferor, the Company shall execute, and the Trustee shall authenticate and
make available for delivery, such Physical Note.

     (l) Private Placement Legend. Upon the transfer, exchange or replacement of
Notes not bearing the Private Placement Legend, the Registrar shall deliver
Notes that do not bear the Private Placement Legend. Upon the transfer, exchange
or replacement of Notes bearing the Private Placement Legend, the Registrar
shall deliver only Notes that bear the Private Placement Legend, unless (i) the
requested transfer is after the relevant Resale Restriction Termination Date
with respect to such Notes, (ii) upon written request of the Company after there
is delivered to the Registrar an opinion of counsel (which opinion and counsel
are satisfactory to the Company and the Trustee) to the effect that neither such
legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act, (iii) with
respect to an Offshore Global Note, with the agreement of the Company on or
after the Offshore Note Exchange Date with respect to such Note, (iv) such Notes
are sold or exchanged pursuant to an effective registration statement under the
Securities Act or (v) such Notes are sold pursuant to Section 3.14(f).

     (m) General. By its acceptance of any Note bearing the Private Placement
Legend, each Holder of such a Note acknowledges the restrictions on transfer of
such Note set forth in this Indenture and in the Private Placement Legend and
agrees that it will transfer such Note only as provided in this Indenture.

     The Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 3.13 or this Section 3.14 (including
all Notes received for transfer pursuant to this Section 3.14). The Company
shall have the right to require the Registrar to deliver to the Company, at the
Company's expense, copies of all such letters, notices or other written
communications at any reasonable time upon the giving of reasonable written
notice to the Registrar.

     In connection with any transfer of any Note, the Trustee, the Registrar and
the Company shall be entitled to receive, shall be under no duty to inquire
into, may conclusively presume the correctness of, and shall be fully protected
in relying upon the certificates, opinions and other information referred to
herein (or in the forms provided

                                       53
<PAGE>

herein, attached hereto or to the Notes, or otherwise) received from any Holder
and any transferee of any Note regarding the validity, legality and due
authorization of any such transfer, the eligibility of the transferee to receive
such Note and any other facts and circumstances related to such transfer.

     (n) Certain Additional Terms Applicable to Physical Notes. Any transferee
entitled to receive a Physical Note may request that the principal amount
thereof be evidenced by one or more Physical Notes in any authorized
denomination or denominations and the Registrar shall comply with such request
if all other transfer restrictions are satisfied.

                                   ARTICLE 4
                                   Covenants

     Section 4.01. Payment of Principal, Premium and Interest. (a) The Company
will duly and punctually pay the principal of (and premium, if any) and interest
and Liquidated Damages, if any, on the Notes in accordance with the terms of the
Notes and this Indenture. An installment of principal (and premium, if any) or
interest and Liquidated Damages shall be considered paid on the date it is due
if the Trustee or Paying Agent or Paying Agents hold on that date money
designated for and sufficient to pay the installment.

     (b) Payments (including principal, premium, if any, interest and Liquidated
Damages, if any) in respect of the Notes represented by the Global Notes, the
Holder of which has given wire transfer instructions on or prior to the relevant
record date, shall be made by wire transfer of immediately available funds to
the accounts specified by the Global Note Holder. With respect to Physical
Notes, the Company will make all payments of principal, premium, if any,
interest and Liquidated Damages, if any, at the office or agency maintained by
the Company in The City of New York referred to in Section 4.02 or, at the
option of the Company, by mailing a check to each such Holder's registered
address.

     Section 4.02. Maintenance of Office or Agency. The Company will maintain in
the Borough of Manhattan, The City of New York an office or agency where Notes
may be presented or surrendered for payment, where Notes may be surrendered for
transfer or exchange and where notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Company will give
prompt written notice to the Trustee of the location, and of any change in the
location, of such office or agency. If at any time the Company shall fail to
maintain such office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee. The Company hereby
designates the Corporate Trust Office as an initial Place of Payment and as such
office of the Company in the Borough of Manhattan, The City of New York, and
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands so long as such Corporate Trust Office remains a Place of
Payment.

     Section 4.03. Money for Payments to Be Held in Trust. If the Company shall
at any time act as its own Paying Agent, it will, on or before each due date of
the principal

                                       54
<PAGE>

of (and premium, if any) or interest and Liquidated Damages, if any, on, any of
the Notes, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
and Liquidated Damages, if any, so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided, and will promptly
notify the Trustee of its action or failure so to act.

     If the Company is not acting as its own Paying Agent, it will, prior to
each due date of the principal of (and premium, if any) or interest and
Liquidated Damages, if any, on, any Notes, deposit with a Paying Agent a sum
sufficient to pay the principal (and premium, if any) or interest and Liquidated
Damages, if any, so becoming due, such sum to be held in trust for the benefit
of the Persons entitled to such principal, premium or interest and Liquidated
Damages, and (unless such Paying Agent is the Trustee) the Company will promptly
notify the Trustee of its action or failure so to act.

     If the Company is not acting as its own Paying Agent, the Company will
cause any Paying Agent other than the Trustee to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee,
subject to the provisions of this Section 4.03, that such Paying Agent will:

     (a) hold all sums held by it for the payment of principal of (and premium,
if any) or interest and Liquidated Damages, if any, on Notes in trust for the
benefit of the Persons entitled thereto until such sums shall be paid to such
Persons or otherwise disposed of as herein provided;

     (b) give the Trustee notice of any default by the Company (or any other
obligor upon the Notes) in the making of any such payment of principal (and
premium, if any) or interest and Liquidated Damages, if any;

     (c) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

     (d) acknowledge, accept and agree to comply in all respects with the
provisions of this Indenture and TIA relating to the duties, rights and
liabilities of such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Company or such
Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such
Paying Agent shall be released from all further liability with respect to such
money.

     Any money deposited with the Trustee or any Paying Agent, or then held by
the Company, in trust for the payment of the principal of (and premium, if any)
or interest and Liquidated Damages, if any, on any Note and remaining unclaimed
for two years

                                       55
<PAGE>

after such principal (and premium, if any) or interest and Liquidated Damages,
if any, has become due and payable shall be paid in the appropriate proportion
to the Company upon a Company Request, or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease.

     Section 4.04. SEC Reports. (a) Whether or not required by the rules and
regulations of the SEC, so long as any Notes issued hereunder are outstanding,
the Company will furnish to each Trustee and the Holders of Notes (i) all
quarterly and annual financial information that would be required to be
contained in a filing with the SEC on Forms 10-Q and 10-K if the Company were
required to file such Forms, including a "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and, with respect to the
annual information only, a report thereon by the Company's certified independent
accountants and (ii) all current reports that would be required to be filed with
the SEC on Form 8-K if the Company were required to file such reports. In
addition, whether or not required by the rules and regulations of the SEC, the
Company will file a copy of all such information and reports with the SEC for
public availability and make such information available to securities analysts
and prospective investors upon request.

     (b) For so long as any Notes remain outstanding, the Company will furnish
to the Holders and to securities analysts and prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act.

     (c) All obligors on the Notes will comply with Section 314(a) of the TIA.

     (d) The Company shall promptly mail copies of all such annual reports,
information, documents and other reports provided to the Trustee pursuant to
clauses (a) and (c) hereof to the Holders at their addresses appearing in the
Register maintained by the Registrar.

     (e) Delivery of such reports, information and documents to the Trustee is
for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officer's Certificates).

     Section 4.05. Certificates to Trustee. (a) The Company will deliver to the
Trustee within 120 days after the end of each fiscal year of the Company a
certificate from the principal executive, financial or accounting officer of the
Company stating that such officer has conducted or supervised a review of the
activities of the Company and its Restricted Subsidiaries and the Company's and
its Restricted Subsidiaries' performance under this Indenture and that, based
upon such review, to the best of such officer's knowledge, the Company has
fulfilled all obligations thereunder or, if there has

                                       56
<PAGE>

been a default in the fulfillment of any such obligation (determined without
regard to any period of grace or requirement of notice provided in this
Indenture), specifying each such default and the nature and status thereof.

     (b) The Company will deliver to the Trustee, as soon as possible and in any
event within 30 days after the Company becomes aware of an Event of Default or a
Default, an Officer's Certificate setting forth the details of such Event of
Default or Default, and the action which the Company proposes to take or has
taken with respect thereto.

     (c) The Company will deliver to the Trustee within 120 days after the end
of each fiscal year of the Company a written statement by the Company's
independent public accountants stating (i) that their audit examination has
included a review of the terms of this Indenture and the Notes as they relate to
accounting matters, and (ii) whether, in connection with their audit
examination, any Default has come to their attention and, if such a Default has
come to their attention, specifying the nature and period of the existence
thereof.

     Section 4.06.  Limitation on Indebtedness. (a) On or after the Issue Date:

          (i)   the Company will not, and will not permit any of its Restricted
     Subsidiaries to, directly or indirectly, create, incur, issue, assume,
     Guarantee or otherwise become directly or indirectly liable, contingently
     or otherwise, with respect to (collectively, "incur") any Indebtedness
     (including Acquired Debt);

          (ii)  the Company will not, and will not permit any of its Restricted
     Subsidiaries to, issue any Disqualified Stock (including Acquired
     Disqualified Stock);

          (iii) and the Company will not permit any of its Restricted
     Subsidiaries that are not Subsidiary Guarantors to issue any shares of
     Preferred Stock (including Acquired Preferred Stock);

provided, however, that the Company and the Subsidiary Guarantors may incur
Indebtedness (including Acquired Debt) and the Company and the Subsidiary
Guarantors may issue shares of Disqualified Stock (including Acquired
Disqualified Stock) if the Fixed Charge Coverage Ratio for the Company's most
recently ended four full fiscal quarters for which financial statements have
been filed with the SEC pursuant to Section 4.04 immediately preceding the date
on which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period.
Letters of credit and bankers' acceptances shall be deemed to have an aggregate
principal amount of Indebtedness equal to the maximum amount available
thereunder.

     (b)  The foregoing provisions will not apply to:

                                       57

     Existing Credit Facility (and by its Subsidiaries of Guarantees thereof) in
     an aggregate principal amount at any time outstanding not to exceed an
     amount equal to $3.477 billion less the aggregate amount of all mandatory
     repayments (other than mandatory prepayments triggered solely by the
     issuance of Indebtedness or Preferred Stock of a Finance Subsidiary to
     refinance the Existing Credit Facility) applied after the Existing Notes
     Issue Date to (x) repay loans (other than revolving credit loans)
     outstanding thereunder or (y) permanently reduce the revolving credit
     commitments thereunder;

          (ii)  the incurrence by the Company and the Subsidiary Guarantors of
     Indebtedness represented by the Notes (other than Additional Notes) and the
     Subsidiary Guarantees thereof;

          (iii) the incurrence by the Company and its Restricted Subsidiaries of
     Existing Indebtedness (other than Indebtedness of the type described in

     Subsidiaries of any Permitted Refinancing in exchange for, or the net
     proceeds of which are used to extend, refinance, renew, replace, defease or
     refund, Indebtedness that was permitted to be incurred under the Fixed
     Charge Coverage Ratio test set forth above or clause (ii) or (iii) above or
     (xiii) or (xiv) below or this clause (iv);

          (v)   the incurrence by the Company or any of its Restricted
     Subsidiaries of intercompany Indebtedness between or among the Company and
     any of its Restricted Subsidiaries; provided, however, that (i) if the
     Company or any Subsidiary Guarantor is the obligor on such Indebtedness,
     such Indebtedness is expressly subordinated to the prior payment in full in
     cash of all Obligations with respect to the Notes or the Subsidiary
     Guarantee, as the case may be, and (ii)(A) any subsequent issuance or
     transfer of Equity Interests that results in any such Indebtedness being
     held by a Person other than the Company or a Restricted Subsidiary and (B)
     any sale or other transfer of any such Indebtedness to a Person that is not
     either the Company or a Restricted Subsidiary shall be deemed, in each
     case, to constitute an incurrence of such Indebtedness by the Company or
     such Restricted Subsidiary, as the case may be;

          (vi)  the incurrence by the Company or any Restricted Subsidiary of
     Hedging Obligations that are incurred for the purpose of (A) fixing or
     hedging interest rate or currency risk with respect to any fixed or
     floating rate Indebtedness that is permitted by the Indenture to be
     outstanding or any receivable or liability the payment of which is
     determined by reference to a foreign currency; provided that the notional
     principal amount of any such Hedging Obligation does not exceed the
     principal amount of the Indebtedness to which such Hedging Obligation
     relates or (B) fixing or hedging risk with respect to fluctuations in the
     cost of raw materials; provided that such obligation is entered into for
     valid business purposes other than speculative purposes (as

                                       58
<PAGE>

     determined by the Company's or such Restricted Subsidiary's principal
     financial officer in the exercise of his or her good faith business
     judgment);

          (vii)  the issuance by any of the Company's Restricted Subsidiaries of
     shares of Preferred Stock to the Company or a Wholly Owned Restricted
     Subsidiary; provided that (A) any subsequent issuance or transfer of Equity
     Interests that results in such Preferred Stock being held by a Person other
     than the Company or a Wholly Owned Restricted Subsidiary or (B) the
     transfer or other disposition by the Company or a Wholly Owned Restricted
     Subsidiary of any such shares to a Person other than the Company or a
     Wholly Owned Restricted Subsidiary shall be deemed, in each case, to
     constitute an issuance of such Preferred Stock by such Subsidiary on such
     date that is not permitted by this clause (vii);

          (viii) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness represented by tender, bid, performance,
     government contract, surety or appeal bonds, standby letters of credit and
     warranty and contractual service obligations of like nature, trade letters
     of credit or documentary letters of credit, in each case to the extent
     incurred in the ordinary course of business of the Company or such
     Restricted Subsidiary and the incurrence by the Company of Indebtedness
     represented by letters of credit incurred in connection with the PBGC
     Settlement;

          (ix)   the incurrence by any Restricted Subsidiary of the Company of
     Indebtedness or the issuance by any Restricted Subsidiary of Preferred
     Stock, the aggregate principal amount or liquidation preference of which,
     together with all other Indebtedness and Preferred Stock of the Company's
     Restricted Subsidiaries at the time outstanding and incurred or issued in
     reliance upon this clause (ix), does not exceed $50.0 million;

          (x)    the issuance by any Finance Subsidiary of Preferred Stock with
     an aggregate liquidation preference not exceeding the amount of
     Indebtedness of the Company held by such Finance Subsidiary; provided that
     the Fixed Charge Coverage Ratio for the Company's most recently ended four
     full fiscal quarters for which financial statements have been filed with
     the SEC pursuant to the covenant described below under Section 4.04
     immediately preceding the date on which such Preferred Stock is issued
     would have been at least 2.0 to 1, determined on a pro forma basis
     (including a pro forma application of the net proceeds therefrom) as if
     such Preferred Stock had been issued at the beginning of such four-quarter
     period;

          (xi)   the incurrence of Indebtedness by Foreign Subsidiaries in an
     aggregate principal amount (or accreted value, as applicable) at any time
     outstanding and incurred in reliance upon this clause (xi) not to exceed
     $100.0 million;

                                       59
<PAGE>

          (xii)  the Guarantee by any Restricted Subsidiary of Indebtedness of
     the Company or a Restricted Subsidiary that was permitted to be incurred by
     another provision of this covenant;

          (xiii) Acquired Debt or Acquired Disqualified Stock; provided that
     such Indebtedness or Disqualified Stock was not incurred in connection with
     or in contemplation of such Person's becoming a Restricted Subsidiary; and
     provided further that immediately after giving effect to such incurrence,
     the Fixed Charge Coverage Ratio for the Company's most recently ended four
     full fiscal quarters for which financial statements have been filed with
     the SEC pursuant to Section 4.04 immediately preceding the date of such
     incurrence would have been at least 2.0 to 1, determined on a pro forma
     basis;

          (xiv)  Indebtedness or Disqualified Stock of a Specified Joint Venture
     or a Subsidiary thereof existing at the time such Specified Joint Venture
     first becomes a Restricted Subsidiary; provided that such Indebtedness or
     Disqualified Stock was not incurred in connection with or in contemplation
     of such Specified Joint Venture's becoming a Restricted Subsidiary; and
     provided further that immediately after giving effect to such Specified
     Joint Venture's becoming a Restricted Subsidiary, the Fixed Charge Coverage
     Ratio for the Company's most recently ended four full fiscal quarters for
     which financial statements have been filed with the SEC pursuant to Section
     4.04 immediately preceding the date on which such Specified Joint Venture
     became a Restricted Subsidiary would have been, determined on a pro forma
     basis, (x) at least 2.0 to 1 or (y) equal to or greater than it was
     immediately prior to such Specified Joint Venture's becoming a Restricted
     Subsidiary;

          (xv)   with respect to any Specified Joint Venture that becomes a
     Restricted Subsidiary, the incurrence by such Specified Joint Venture of
     Indebtedness under any revolving credit facility in an aggregate principal
     amount at any time outstanding not to exceed the aggregate principal amount
     of committed financing under all revolving credit facilities of such
     Specified Joint Venture as in effect on the Issue Date; and

          (xvi)  the incurrence by the Company or any Subsidiary Guarantor of
     Indebtedness in an aggregate principal amount (or accreted value, as
     applicable) at any time outstanding and incurred in reliance on this clause
     (xvi) not to exceed $25.0 million.

     (c)  For purposes of determining compliance with this covenant, in the
event that an item of Indebtedness or Preferred Stock meets the criteria of more
than one of the categories of permitted Indebtedness described in clauses (i)
through (xvi) above or is entitled to be incurred pursuant to Section 4.06(a),
the Company shall, in its sole discretion, classify such item of Indebtedness or
Preferred Stock in any manner that complies with this covenant and such
Indebtedness or Preferred Stock will be treated as having been incurred pursuant
to the clauses or Section 4.06(a), as the case may be, designated by the
Company. The amount of Indebtedness issued at a price which is less

                                       60
<PAGE>

than the principal amount thereof shall be equal to the amount of the liability
in respect thereof determined in accordance with GAAP.

and will not permit any of its Restricted Subsidiaries to, directly or
indirectly:

          (i)   declare or pay any dividend or make any distribution on account
     of the Company's or any of its Restricted Subsidiaries' Equity Interests
     (other than (x) dividends or distributions payable in Qualified Equity
     Interests of the Company and (y) dividends or distributions payable to the
     Company or any Restricted Subsidiary of the Company);

          (ii)  purchase, redeem or otherwise acquire or retire for value any

          (iii) make any principal payment on, or purchase, redeem, defease or
     otherwise acquire or retire for value any Indebtedness ("Subordinated
     Debt") of the Company or any Restricted Subsidiary that is subordinated by
     its terms to the Notes or the Subsidiary Guarantees (other than
     Indebtedness owed to the Company or any Restricted Subsidiary), except, in
     each case, payment of interest or principal at Stated Maturity; or

          (iv)  make any Restricted Investment (all such payments and other
     actions set forth in clauses (i) through (iv) above being collectively
     referred to as "Restricted Payments");

unless, at the time of and after giving effect to such Restricted Payment (the
amount of any such Restricted Payment, if other than cash, shall be the fair
market value (as conclusively evidenced by a Board Resolution) of the asset(s)
proposed to be transferred by the Company or such Restricted Subsidiary, as the
case may be, pursuant to such Restricted Payment):

     (A)  no Default or Event of Default shall have occurred and be continuing
after giving effect thereto; and

     (B)  the Company would, at the time of such Restricted Payment and after

          statements have been filed with the SEC pursuant to Section 4.04 at
          the time of such Restricted Payment (or, if such Consolidated Net
          Income for such period is a deficit, less 100% of such deficit), plus

          (ii)  100% of the aggregate net cash proceeds received by the Company

          such Subsidiary) of the fair market value of the net assets of an
          Unrestricted Subsidiary at the time such Unrestricted Subsidiary is
          designated a Restricted Subsidiary; provided, however, that the
          foregoing sum shall not exceed, in the case of any Unrestricted
          Subsidiary, the amount of Restricted Investments (other than
          Restricted Investments permitted to be made pursuant to Section

occurred and be continuing after giving effect to such Restricted Payment, the
foregoing provisions will not prohibit the following Restricted Payments:

     thereof are used to purchase or redeem an interest of another Person in
     such Specified Joint Venture (other than the Company, a Restricted
     Subsidiary or an Affiliate of the Company, except a Person that is deemed
     to be an Affiliate solely by virtue of its ownership of Equity Interests of
     the Company acquired in exchange for Equity Interests in such Specified
     Joint Venture); provided that after giving pro forma effect thereto as if
     such Restricted Payment (and any related incurrence of Indebtedness) had

          acquired in exchange for Equity Interests in such Specified Joint
          Venture) of a Specified Joint Venture that immediately prior to such

     exceed $100.0 million and (B) the pledge of the Capital Stock of such Joint
     Venture or Unrestricted Subsidiary or of a Joint Venture Subsidiary that

     Joint Venture or Unrestricted Subsidiary or Rhodia or a wholly-owned
     subsidiary of Rhodia;

          (xiii) the repurchase of any Subordinated Debt at a purchase price not

     to a provision no more favorable to the holders thereof than the provisions
     of Section 4.09; provided that, in each case, prior to such repurchase the
     Company has made a Change of Control Offer or Asset Sale Offer, as
     applicable, and repurchased all Notes that were validly tendered for
     payment in connection with such Change of Control Offer or Asset Sale
     Offer;

          (xiv)  distributions by any Restricted Subsidiary or Joint Venture of

     with the establishment of such Joint Venture or Restricted Subsidiary that
     requires such holder to pay a price for such chemicals equal to that which

     requirement);

          (xv)   any other Restricted Payment that, together with all other
     Restricted Payments made pursuant to this Section 4.07(b)(xv) on or after
     the Existing Notes Issue Date, does not exceed $25 million (after giving

     after giving effect to such dividends or distributions and any related
     transactions, the Joint Venture making such dividends or distributions to
     such holders is contractually entitled to receive, and receives within 180
     days before or after the date of such dividends or distributions, directly
     or indirectly, an equivalent or larger cash payment from each such holder
     (other than from a holder that is the Company or any Restricted Subsidiary)
     or from an Affiliate of such holder, which cash payment has not been
     previously applied pursuant to this Section 4.07(b)(xvi) to offset any
     other dividend or distribution by such Joint Venture to such holder and (y)
     such dividends or distributions do not exceed such holders' pro rata share
     of the Joint Venture's cash flows from operating activities, minus any non-
     cash charge to the extent that it represents an accrual of or reserve for

     expenditures in any future period or amortization of a prepaid cash expense
     in any future period.

     (c) The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries in the Subsidiary so
designated will be deemed to be Restricted Payments at the time of such
designation and will reduce the amount available for Restricted Payments Section
4.07(a) (except to the extent such Investments were repaid in cash, and, in the
case of a Joint Venture (and any Subsidiary of a Joint Venture) designated as an
Unrestricted Subsidiary on the first day that it is a Subsidiary of the Company,
except to the extent that (1) such Investments were made after the Existing
Notes Issue Date or (2) in the case of a Specified Joint Venture, such
Investments were made prior to the Existing Notes Issue Date). All such
outstanding Investments (except as provided in the parenthetical included in the
preceding sentence) will be deemed to constitute Investments in an amount equal
to the fair market value of such Investments at the time of such designation (as
conclusively determined by the Board of Directors). Such designation will only
be permitted if any such Restricted Payment would be permitted at such time and
if such Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary. In the case of any designation by the Company of a Person as an
Unrestricted Subsidiary on the first day that such Person is a Subsidiary of the
Company in accordance with the provisions of the Indenture, such designation
shall be deemed to have occurred for all purposes of the Indenture
simultaneously with, and automatically upon, such Person becoming a Subsidiary.

     (d) Not later than the date of making any Restricted Payment, other than
those permitted by Sections 4.07(b)(ii)(x), 4.07(b)(vi), 4.07(b)(x) and
4.07(b)(xiv) above, and not later than the 120th day after making any Restricted
Payment permitted by Section 4.07(b)(vi) above, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.07 were computed.

     (e) For purposes of this covenant, any payment made on or after the
Existing Notes Issue Date but prior to the Issue Date shall be deemed to be a
"Restricted Payment" to the extent such payment would have been a Restricted
Payment had the Indenture been in effect at the time of such payment (and, to
the extent that any such Restricted Payment was permitted by clauses (b)(i)
through (xvi) above, such Restricted Payment may be deemed by the Company to
have been made pursuant to such clause).

     Section 4.08. Limitation on Dividend and other Payment Restrictions
Affecting Restricted Subsidiaries and Joint Ventures. (a) The Company will not,
and will not permit any of its Restricted Subsidiaries to, directly or
indirectly, create or otherwise cause or suffer to exist or become effective any
restriction on the ability of any Restricted Subsidiary to:

          (i) (A) pay dividends or make any other distributions to the Company
     or any of its Restricted Subsidiaries (1) on its Capital Stock, or (2) with
     respect

                                       67
<PAGE>

     to any other interest or participation in, or measured by, its profits, or
     (B) pay any Indebtedness owed to the Company or any of its Restricted
     Subsidiaries;

          (ii)   make loans or advances to the Company or any of its Restricted
     Subsidiaries; or

          (iii)  transfer any of its properties or assets to the Company or
     any of its Restricted Subsidiaries;

 except for such restrictions existing under or by reason of:

     (a) existing agreements as in effect on the Issue Date;

     (b) Indebtedness permitted by the Indenture to be incurred containing
restrictions on the ability of Restricted Subsidiaries to consummate
transactions of the types described in clause (i), (ii) or (iii) above not
materially more restrictive than those contained in the Indenture;

     (c) the Indenture;

     (d) applicable law;

     (e) existing restrictions with respect to a Person acquired by the Company
or any of its Restricted Subsidiaries (except to the extent such restrictions
were put in place in connection with or in contemplation of such acquisition),
which restrictions are not applicable to any Person, or the properties or assets
of any Person, other than the Person, or the property or assets of the Person,
so acquired;

     (f) customary non-assignment provisions in leases and other agreements
entered into in the ordinary course of business;

     (g) construction loans and purchase money obligations (including Capital
Lease Obligations) for property acquired in the ordinary course of business that
impose restrictions of the nature described in clause (iii) above on the
property so constructed or acquired;

     (h) in the case of clause (iii) above, restrictions contained in security
agreements or mortgages securing Indebtedness of a Restricted Subsidiary to the
extent such restrictions restrict the transfer of the property subject to such
security agreements or mortgages;

     (i) a Permitted Refinancing, provided that the restrictions contained in
the agreements governing such Permitted Refinancing are not materially more
restrictive, taken as a whole, than those contained in the agreements governing
the Indebtedness being refinanced (as conclusively evidenced by a Board
Resolution);

     (j) customary restrictions on a Finance Subsidiary imposed in such Finance
Subsidiary's organizational documents or by the terms of its Preferred Stock;

                                       68
<PAGE>

     (k) any restriction with respect to shares of Capital Stock of a Restricted
Subsidiary imposed pursuant to an agreement entered into for the sale or
disposition of such shares of Capital Stock or any restriction with respect to
the assets of a Restricted Subsidiary imposed pursuant to an agreement entered
into for the sale or disposition of such assets or all or substantially all the
Capital Stock of such Restricted Subsidiary pending the closing of such sale or
disposition;

     (l) in the case of any Restricted Subsidiary that is a Joint Venture,
customary restrictions on such Restricted Subsidiary contained in its joint
venture agreement, which restrictions are consistent with the past practice of
the Company and its Restricted Subsidiaries (as conclusively evidenced by a
Board Resolution);

     (m) existing restrictions with respect to a Specified Joint Venture or the
property or assets thereof or a Subsidiary of a Specified Joint Venture or the
property or assets thereof, in each case, at the time such Specified Joint
Venture first becomes a Restricted Subsidiary (except to the extent such
restrictions were put in place in connection with or in contemplation of such
Specified Joint Venture becoming a Restricted Subsidiary), which restrictions
are not applicable to any Person, or the properties or assets of any Person,
other than such Specified Joint Venture or the property or assets thereof or a
Subsidiary of such Specified Joint Venture or the property or assets thereof;
and

     (n) the Existing Credit Facility and related documentation as the same is
in effect on the Issue Date and as amended, modified, extended, renewed,
refunded, refinanced, restated or replaced from time to time; provided that the
Existing Credit Facility and related documentation as so amended, modified,
extended, reviewed, refunded, refinanced, restated or replaced is not materially
more restrictive, taken as a whole, as to the matters enumerated above than the
Existing Credit Facility and related documentation as in effect on the Issue
Date (as conclusively evidenced by a Board Resolution).

     For purposes of determining compliance with this covenant, in the event
that a restriction meets the criteria of more than one of the categories of
permitted restrictions described in clauses (a) through (n) above, the Company
shall, in its sole discretion, classify such restriction in any manner that
complies with this covenant, and such restriction will be treated as existing
pursuant to the clauses designated by the Company.

     (b) The Company will use best efforts (consistent with its contractual
obligations and fiduciary duties to any Joint Venture, in each case, as in
effect on the Issue Date) not to permit any of its Joint Ventures that are not
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any restriction on the ability of such Joint
Venture to:

         (i) (A) pay dividends or make any other distributions to the Company or
     any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with
     respect to any other interest or participation in, or measured by, its
     profits or (B) pay any Indebtedness owed to the Company or any of its
     Restricted Subsidiaries;

                                       69

          (ii)   make loans or advances to the Company or any of its Restricted
     Subsidiaries; or

          (iii)  transfer any of its properties or assets to the Company or any

except for such restrictions existing under or by reason of:

     (a)  such Joint Venture's joint venture agreement or its credit facility
(provided that in each case such restrictions are consistent with the past
practice of the Company);

     (b)  in the case of any Joint Venture existing on the Issue Date, its
existing agreements as in effect on the date of the Indenture and as amended,
modified, extended, restated or replaced from time to time; provided that no
such amendment, modification, extension, restatement or replacement results in
agreements that are materially more restrictive, taken as a whole, as to the
matters enumerated above than the existing agreements as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution);

     (c)  in the case of LCR, any instrument governing its Indebtedness; and

     (d)  the restrictions described in clauses (d), (e), (f), (g), (h), (j),
(k) and (n) of Section 4.08(a) (assuming that references in clauses (h) and (k)
to a Restricted Subsidiary were references to a Joint Venture).

     Section 4.09. Limitation on Sales of Assets. (a) The Company will not, and
will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale
unless:

          (i)  the Company and/or the Restricted Subsidiary, as the case may be,
     receives consideration at the time of such Asset Sale at least equal to the
     fair market value (as conclusively evidenced by a Board Resolution set
     forth in an Officers' Certificate delivered to the Trustee) of the assets
     or Equity Interests issued or sold or otherwise disposed of; and

          (ii) at least 80% of the consideration therefor received by the
     Company and/or such Restricted Subsidiary is in the form of

               (A) cash or Cash Equivalents or

               (B) a controlling interest or a joint venture interest (to the
          extent otherwise permitted by the Indenture) in a business engaged in
          a Permitted Business or long-term property or assets that are used or
          useful in a Permitted Business;

     provided that the amount of (x) any liabilities (as shown on the Company's
     or such Restricted Subsidiary's most recent balance sheet) of the Company
     or any Restricted Subsidiary (other than contingent liabilities and
     liabilities that are by their terms subordinated to the Notes or any
     guarantee thereof) that are assumed

                                       70
<PAGE>

     by the transferee of any such assets pursuant to a customary novation
     agreement that releases the Company or such Restricted Subsidiary from
     further liability and (y) any securities, notes or other obligations
     received by the Company or any such Restricted Subsidiary from such
     transferee that are promptly converted by the Company or such Restricted
     Subsidiary into cash (to the extent of the cash received), shall be deemed
     to be cash for purposes of this provision.

     (b)  Within 360 days after the receipt of any Net Proceeds from an Asset
Sale, the Company may apply such Net Proceeds, at its option:

               (i)  to permanently repay Senior Indebtedness (and to
     correspondingly reduce commitments with respect thereto in the case of
     revolving borrowings) of the Company or a Subsidiary Guarantor or
     Indebtedness (and to correspondingly reduce commitments with respect
     thereto in the case of revolving borrowings) of any Restricted Subsidiary
     that is not a Subsidiary Guarantor; provided that, so long as the
     provisions of Section 4.12 are in effect, only repayment of Senior
     Indebtedness incurred under the Existing Credit Facility (but not any
     refinancing thereof other than a credit facility with commercial banks and
     other lenders) shall constitute a repayment of Indebtedness permitted
     pursuant to this clause (i); or

               (ii) to acquire a controlling interest or a joint venture
     interest (to the extent otherwise permitted by the Indenture) in another
     business or, the making of a capital expenditure or the acquisition of
     other long-term assets, in each case, in a Permitted Business (or enter
     into a binding commitment for any such expenditure or acquisition);
     provided that such binding commitment shall be treated as a permitted
     application of Net Proceeds from the date of such commitment until and only
     until the earlier of (x) the date on which such expenditure or acquisition
     is consummated and (y) the 180th day following the expiration of the
     aforementioned 360 day period. If the expenditure or acquisition
     contemplated by such binding commitment is not consummated on or before
     such 180th day and the Company shall not have applied such Net Proceeds
     pursuant to clause (i) above on or before such 180th day, such commitment
     shall be deemed not to have been a permitted application of Net Proceeds at
     any time;

provided that, so long as the provisions of Section 4.12 are in effect, the
Company may not apply Net Proceeds of a Significant Asset Sale pursuant to
clause (ii) above to satisfy its obligations to apply such proceeds pursuant to
this paragraph except to the extent that the provisions of the Existing Credit
Facility (but not any refinancing thereof other than a credit facility with
commercial banks and other lenders) require a mandatory prepayment from such
proceeds but the requisite lenders thereunder have waived such mandatory
prepayment.

     Pending the final application of any such Net Proceeds, the Company may
temporarily reduce the revolving Indebtedness under the Existing Credit Facility
or otherwise invest such Net Proceeds in any manner that is not prohibited by
the Indenture.

                                       71
<PAGE>

Any Net Proceeds from Asset Sales that are not applied or invested as provided
in the first sentence of this Section 4.09(b) will be deemed to constitute
"Excess Proceeds."

     (c)  When the aggregate amount of Excess Proceeds exceeds $25 million, the
Company will be required to make an offer to all Holders of Notes (an "Asset
Sale Offer") to purchase the maximum principal amount of Notes and, (x) if the
Company is required to do so under the terms of any other Indebtedness ranking
pari passu with such Notes, such other Indebtedness, and (y) if the Company
elects to do so, any Existing ARCO Chemical Debt, on a pro rata basis with the
Notes, that may be purchased out of the Excess Proceeds, at an offer price in
cash in an amount equal to 100% of the principal amount thereof plus accrued and
unpaid interest and Liquidated Damages, if any, thereon to the date of purchase,
in accordance with the procedures set forth herein.

     To the extent that the aggregate amount of Notes (and any other pari passu
Indebtedness subject to such Asset Sale Offer) tendered pursuant to such Asset
Sale Offer is less than the Excess Proceeds, the Company may, subject to the
other terms of the Indenture, use any remaining Excess Proceeds for general
corporate purposes.

     If the aggregate principal amount of Notes surrendered by Holders thereof
in connection with an Asset Sale Offer exceeds the amount of Excess Proceeds,
the Trustee shall select the Notes to be purchased on a pro rata basis.

     Upon completion of the offer to purchase made under the Indenture, the
amount of Excess Proceeds shall be reset at zero.

     (d)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with any Asset
Sale Offer.

     Section 4.10. Limitation on Affiliate Transactions. (a) The Company will
not, and will not permit any of its Restricted Subsidiaries to, sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or purchase
any property or assets from, or enter into or make any contract, agreement,
understanding, loan, advance or Guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless (i) such
Affiliate Transaction is on an arm's-length basis and (ii) the Company delivers
to the Trustee (a) with respect to any Affiliate Transaction involving aggregate
consideration in excess of $10 million, a Board Resolution set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (i) above and that such Affiliate Transaction has been approved by a
majority of the disinterested members of the Board of Directors and (b) with
respect to any Affiliate Transaction involving aggregate consideration in excess
of $25 million, an opinion as to the fairness to the Company or such Restricted
Subsidiary of such Affiliate Transaction from a financial point of view issued
by an investment banking firm of national standing; provided that:

     (i) transactions or payments pursuant to any employment arrangements or
employee, officer or director benefit plans or arrangements entered into by the
Company or any of its Restricted Subsidiaries in the ordinary course of
business;

                                       72
<PAGE>

     (ii)  transactions between or among the Company and/or its Restricted
Subsidiaries;

     (iii) any Restricted Payment permitted by Section 4.07 of the type
described in clause (i) or (ii) of the first paragraph thereof;

     (iv)  customary loans, advances, fees and compensation paid to, and
indemnity provided on behalf of, officers, directors, employees or consultants
of the Company or any of its Restricted Subsidiaries;

     (v)   transactions entered into on an arm's-length basis in the ordinary
course of business between the Company or any of its Restricted Subsidiaries and
any Joint Venture;

     (vi)  sales (including a sale in exchange for a promissory note of or
Equity Interest in such Accounts Receivable Subsidiary) of accounts receivable
and the provision of billing, collection and other services in connection
therewith, in each case, to an Accounts Receivable Subsidiary in connection with
any Receivables Facility; and

     (vii) transactions pursuant to any contract or agreement in effect on the
date of the Indenture as the same may be amended, modified or replaced from time
to time so long as any such contract or agreement as so amended, modified or
replaced is, taken as a whole, no less favorable to the Company and its
Restricted Subsidiaries than the contract or agreement as in effect on the date
of the Indenture (as conclusively evidenced by a Board Resolution); in each
case, shall not be deemed to be Affiliate Transactions and therefore not subject
to the requirements of clauses (i) and (ii) of the initial sentence above.

     Section 4.11. Limitation on Liens. (a) The Company will not, and will not
permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, assume or suffer to exist any Lien (except Permitted Liens) on any asset
now owned or hereafter acquired, or any income or profits therefrom, unless all
payments due under the Indenture and the Notes or the Subsidiary Guarantees are
secured on an equal and ratable basis with the obligations so secured (or, if
such obligations are subordinated by their terms to the Notes or the Subsidiary
Guarantees, prior to the obligations so secured) until such time as such
obligations are no longer so secured.

     (b) The Company and its Subsidiaries shall also comply with the provisions
of Section 4.12(a) until such provisions cease to be in effect pursuant to
Section 4.12(b).

     Section 4.12. Equal and Ratable Liens. (a) To the extent the Company or any
Subsidiary of the Company grants a Lien upon any of its property or assets to
secure the Existing Credit Facility Obligations, the Company or such Subsidiary,
as the case may be, shall, contemporaneously with the granting of such Lien,
secure the Indenture Obligations equally and ratably with the Existing Credit
Facility Obligations secured by such Lien.

                                       73
<PAGE>

     (b)  Notwithstanding the foregoing, from and after the date when all Liens
granted in favor of the holders of Existing Credit Facility Obligations are
released (and are not concurrently replaced with any new Liens on any asset of
the Company or any of its Restricted Subsidiaries securing Existing Credit
Facility Obligations), the provisions of this Section 4.12 will no longer apply.
The provisions of Section 4.11 will, however, continue to apply.

     Section 4.13. No Amendment to Subordination Provisions. The Company will
not amend, modify or alter the Senior Subordinated Notes Indenture in any way
that would (i) increase the principal of, advance the final maturity date of or
shorten the Weighted Average Life to Maturity of any Senior Subordinated Notes
such that the final maturity date of the Senior Subordinated Notes is earlier
than the 91st day following the final maturity date of the Notes or (ii) amend
the subordination provisions of the Senior Subordinated Notes Indenture or any
of the defined terms used therein in a manner that would be adverse to the
holders of the Notes.

     Section 4.14. Repurchase of Notes upon a Change in Control. (a) Upon the
occurrence of a Change of Control, each Holder will have the right to require
the Company to repurchase all or any part (equal to $1,000 or an integral
multiple thereof) of such Holder's Notes pursuant to the offer described below
(the "Change of Control Offer") at an offer price in cash equal to 101% of the
aggregate principal amount thereof plus accrued and unpaid interest and
Liquidated Damages, if any, thereon to the date of purchase (the "Change of
Control Payment") on a date that is not more than 90 days after the occurrence
of such Change of Control (the "Change of Control Payment Date"). Within 30 days
following any Change of Control, the Company will mail, or at the Company's
request the Trustee will mail, a notice to each Holder offering to repurchase
the Notes held by such Holder pursuant to the procedures specified in such
notice.

     (b)  The Company will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of the Notes as a result of a Change of Control.

     (c)  On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
and not withdrawn pursuant to the Change of Control Offer, (2) deposit with the
Paying Agent an amount equal to the Change of Control Payment in respect of all
Notes or portions thereof so tendered, and (3) deliver or cause to be delivered
to the Trustee the Notes so accepted together with an Officer's Certificate
stating the aggregate principal amount of Notes or portions thereof being
purchased by the Company.

          The Paying Agent will promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a Note equal in principal amount to any unpurchased portion of the
Notes surrendered, if any; provided that each such Note will be in a principal
amount of $1,000 or an integral multiple thereof.

                                       74
<PAGE>

     (d)  The Company will not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer at
the same or a higher purchase price, at the same times and otherwise in
substantial compliance with the requirements applicable to a Change of Control
Offer made by the Company and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer.

     Section 4.15. Limitation on Sale and Leaseback Transactions. The Company
will not, and will not permit any of its Restricted Subsidiaries to, enter into
any Sale and Leaseback Transaction; provided that the Company or any Restricted
Subsidiary may enter into a Sale and Leaseback Transaction if: (a) the Company
or such Restricted Subsidiary, as the case may be, could have (i) incurred
Indebtedness in an amount equal to the Attributable Debt relating to such Sale
and Leaseback Transaction pursuant to the Fixed Charge Coverage Ratio test set
forth in Section 4.06(a) (whether or not such covenant has ceased to be
otherwise in effect pursuant to Section 4.18) and (ii) incurred a Lien to secure
such Indebtedness pursuant to Section 4.11 without securing the Notes; and (b)
the gross cash proceeds of such Sale and Leaseback Transaction are at least
equal to the fair market value (as conclusively determined by the Board of
Directors) of the property that is the subject of such Sale and Leaseback
Transaction.

     Section 4.16. Limitation on Line of Business. The Company will not, and
will not permit any of its Restricted Subsidiaries to, engage in any business
other than Permitted Businesses, except to such extent as would not be material
to the Company and its Subsidiaries taken as a whole.

     Section 4.17. Limitation on Accounts Receivable Facilities. The Company
may, and any of its Restricted Subsidiaries may, sell (including a sale in
exchange for a promissory note of or an Equity Interest in such Accounts
Receivable Subsidiary) at any time and from time to time, accounts receivable to
any Accounts Receivable Subsidiary; provided that the aggregate consideration
received in each such sale is at least equal to the aggregate fair market value
of the receivables sold.

     Section 4.18. Limited Applicability of Covenants when Notes are Rated
Investment-Grade. Notwithstanding the foregoing, the Company's and its
Restricted Subsidiaries' obligations to comply with the provisions of Sections
4.06, 4.07, 4.08, 4.09, 4.10, 4.16, 4.17 and 4.22 will terminate and cease to
have any further effect from and after the first date when the Notes are rated
Investment Grade.

     Section 4.19. Existence. Subject to Articles 4 and 5 of this Indenture, the
Company will do or cause to be done all things necessary to preserve and keep in
full force and effect its existence and the existence of each of its Restricted
Subsidiaries in accordance with the respective organizational documents of the
Company and each such Subsidiary and the rights (whether pursuant to charter,
partnership certificate, agreement, statute or otherwise), material licenses and
franchises of the Company and each such Subsidiary; provided that the Company
shall not be required by this Section 4.19 to preserve any such right, license
or franchise, or the existence of any Restricted Subsidiary, if the Company
shall determine that the maintenance or preservation thereof

                                       75
<PAGE>

is no longer desirable in the conduct of the business of the Company and its
Restricted Subsidiaries taken as a whole.

     Section 4.20. Payment of Taxes and Other Claims. The Company will pay or
discharge and shall cause each of its Restricted Subsidiaries to pay or
discharge, or cause to be paid or discharged, before the same shall become
delinquent (a) all material taxes, assessments and governmental charges levied
or imposed upon (i) the Company or any such Subsidiary, (ii) the income or
profits of any such Subsidiary which is a corporation or (iii) the property of
the Company or any such Subsidiary and (b) all material lawful claims for labor
materials and supplies that, if unpaid, might by law become a lien upon the
property of the Company or any such Subsidiary; provided that the Company shall
not be required to pay or discharge, or cause to be paid or discharged, any such
tax, assessment, charge or claim the amount, applicability or validity of which
is being contested in good faith by appropriate proceedings and for which
adequate reserves have been established in accordance with GAAP.

     Section 4.21. Maintenance of Properties and Insurance. The Company will
cause all material assets necessary in the conduct of its business or the
business of any of its Restricted Subsidiaries, to be maintained and kept in
good condition, repair and working order (ordinary wear and tear excepted) and
will cause to be made all necessary repairs, renewals and replacements thereof,
all as in the judgment of the Company may be necessary so that the business
carried on in connection therewith may be properly conducted at all times;
provided that nothing in this Section 4.21 shall prevent the Company or any such
Subsidiary from discontinuing the use, operation or maintenance of any of such
assets or disposing or abandoning of any of them, if such discontinuance,
disposal or abandonment is, in the judgment of the Company, desirable in the
conduct of the business of the Company or such Subsidiary.

      The Company will maintain, and will cause each of its Restricted
Subsidiaries to maintain (either in the Company's name or in such Subsidiary's
own name) insurance on all their respective properties consistent with the
insurance maintained on the Issue Date or otherwise in at least such amounts
(with no materially greater risk retention) and against at least such risks as
are usually maintained, retained or insured against in the same general area by
companies of established repute owning similar properties in such area and
engaged in the same or a similar business, in either case, to the extent
available to the Company and its Restricted Subsidiaries on commercially
reasonable terms.

     Section 4.22. Limitation on Issuance of Guarantees by Restricted
Subsidiaries. (a) The Company will not permit any Restricted Subsidiary that is
not a Subsidiary Guarantor, directly or indirectly, to Guarantee or secure the
payment of any other Indebtedness of the Company or any of its Restricted
Subsidiaries (except Indebtedness of such Restricted Subsidiary or a Restricted
Subsidiary of such Restricted Subsidiary) unless (i) such Restricted Subsidiary
simultaneously executes and delivers a supplemental indenture in the form of
Exhibit B hereto providing for the Guarantee of the payment of the Notes by such
Restricted Subsidiary and shall deliver an Opinion of Counsel to the Trustee
pursuant to paragraph (c) below; provided that this paragraph shall not be
applicable to (x) any Guarantee of any Restricted Subsidiary that existed at the
time such Person became a Restricted Subsidiary and was not incurred in
connection

                                       76
<PAGE>

with, or in contemplation of, such Person's becoming a Restricted Subsidiary,
(y) Guarantees of Indebtedness of a Restricted Subsidiary that is a Foreign
Subsidiary by a Restricted Subsidiary that is a Foreign Subsidiary or (z) the
granting of Liens by a Joint Venture Subsidiary to secure Indebtedness under the
Existing Credit Facility, the Existing Senior Secured Notes and the Notes. If
the Notes are (A) pari passu with the Guaranteed Indebtedness, then the
Subsidiary Guarantee shall be pari passu with, or senior to, the guarantee of
such Guaranteed Indebtedness or (B) senior to the Guaranteed Indebtedness, then
the Subsidiary Guarantee shall be senior to the guarantee of such Guaranteed
Indebtedness at least to the extent that the Notes are senior to such Guaranteed
Indebtedness.

     (b)  Notwithstanding the foregoing, each Subsidiary Guarantee by a
Restricted Subsidiary shall be automatically and unconditionally released and
discharged upon (i) any sale, exchange or transfer, to any Person not an
Affiliate of the Company, of all the Company's and each Restricted Subsidiary's
Capital Stock in such Restricted Subsidiary (which sale, exchange or transfer is
not prohibited by the Indenture) as provided in Section 5.03(b), (ii) the
release or discharge of the Guarantee which resulted in the creation of such
Subsidiary Guarantee (or, in the case of the Subsidiary Guarantees of ARCO
Chemical Technology, Inc., ARCO Chemical Technology, L.P. and Lyondell Chemical
Nederland, Ltd. issued on the Issue Date, the release or discharge of its
Guarantee of Indebtedness under the Existing Credit Facility and the Existing
Senior Secured Notes), except a discharge or release by or as a result of
payment under such Guarantee, and (iii) the designation of such Restricted
Subsidiary as an Unrestricted Subsidiary in accordance with the terms of the
Indenture.

     (c)  The Opinion of Counsel described above shall be to the effect that
such supplemental indenture has been duly authorized, executed and delivered by
such Subsidiary and constitutes a valid and binding obligation of such
Subsidiary, enforceable against such Subsidiary in accordance with its terms
(subject to customary exceptions).

     Section 4.23.  Payments for Consents. Neither the Company nor any of its
Subsidiaries or Affiliates will, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
of any Notes for or as an inducement to any consent, waiver or amendment of any
of the terms or provisions of the Indenture or the Notes unless such
consideration is offered to be paid or agreed to be paid to all Holders of the
Notes that consent, waive or agree to amend such term or provision in the time
frame set forth in the solicitation documents relating to such consent, waiver
or agreement.

<PAGE>

substantially all its assets in one or more related transactions, to another
corporation, Person or entity unless:

          (i)   the Company is the surviving corporation or the entity or the
     Person formed by or surviving any such consolidation or merger (if other
     than the Company) or to which such sale, assignment, transfer, conveyance
     or other disposition shall have been made is a corporation organized or
     existing under the laws of the United States, any state thereof or the
     District of Columbia;

          (ii)  the corporation formed by or surviving any such consolidation or

     incur at least $1.00 of additional Indebtedness pursuant to the Fixed
     Charge Coverage Ratio test set forth in Section 4.06(a). The foregoing
     shall not prohibit the merger or consolidation of a Wholly Owned Restricted
     Subsidiary with the Company; provided that, in connection with any such
     merger or consolidation, no consideration (other than common stock in the
     surviving Person or the Company) shall be issued or distributed to the
     stockholders of the Company.

     (b)  The Company will not lease all or substantially all its assets to
another Person.

Section 5.02(b), upon any consolidation or merger, or any sale, assignment,
transfer, conveyance or other disposition of all or substantially all the assets
of the Company in accordance with Section 5.01 hereof, the successor corporation
formed by such consolidation or into or with which the Company is merged or to
which such sale, assignment, transfer, conveyance or other disposition is made
shall succeed to, and be substituted for (so that from and after the date of
such consolidation, merger, sale, assignment, transfer, conveyance or other
disposition, the provisions of this Indenture referring to the "Company" shall
refer instead to the successor corporation), and may

                                       78
<PAGE>

exercise every right and power of, the Company under this Indenture with the
same effect as if such successor Person had been named as the Company herein,
and the predecessor Company shall be released from all its obligations hereunder
and under the Notes.

     (b)  The sale, assignment, transfer, lease, conveyance or other disposition
by the Company of all or substantially all its property or assets taken as a
whole to one or more of the Company's Subsidiaries shall not relieve the Company
from its obligations under the Indenture and the Notes.

Guarantor. (a) No Subsidiary Guarantor may consolidate with or merge with or
into (whether or not such Subsidiary Guarantor is the surviving Person), another
corporation, Person or entity whether or not affiliated with such Subsidiary
Guarantor unless:

          (i)   subject to the provisions of Section 5.03(b) below, the Person
     formed by or surviving any such consolidation or merger (if other than the
     Company or such Subsidiary Guarantor) assumes all the obligations of such
     Subsidiary Guarantor, pursuant to a supplemental indenture in form and
     substance reasonably satisfactory to the Trustee, under the Notes;

          (ii)  immediately after giving effect to such transaction, no Default
     or Event of Default exists; and

          (iii) the Company would, at the time of such transaction and after
     giving pro forma effect thereto as if such transaction had occurred at the
     beginning of the applicable four-quarter period, (A) have a Consolidated
     Net Worth immediately after the transaction equal to or greater than the
     Consolidated Net Worth of the Company immediately preceding the transaction
     and (B) except with respect to a consolidation or merger with a Person that
     has no outstanding Indebtedness, be permitted to incur at least $1.00 of
     additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test
     set forth in 4.06(a).

     All the Subsidiary Guarantees issued pursuant to clause (i) above shall in
all respects have the same legal rank and benefit under this Indenture as the
Subsidiary Guarantees theretofore and thereafter issued in accordance with the
terms of this Indenture as though all such Subsidiary Guarantees had been issued
at the date of the execution hereof.

or any of its Significant Subsidiaries if the Company or a Significant
Subsidiary does not perform its payment obligations under such Guarantee within
any grace period provided for in the documentation governing such Guarantee)
and, whether such Indebtedness or Guarantee exists on the date of the indenture
or is thereafter created, which default (a) constitutes a Payment Default or (b)
results in the acceleration of such Indebtedness prior to its Stated Maturity,
and in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a

days;

     (g)  a court having jurisdiction in the premises enters a decree or order
for (i) relief in respect of the Company or any Significant Subsidiary in an
involuntary case under any applicable bankruptcy, insolvency or other similar
law now or hereafter in effect, (ii) appointment of a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Company or
any Significant Subsidiary or for all or substantially all the property and

of creditors;

     (i)  except as permitted by the Indenture, any Subsidiary Guarantee issued
hereunder shall be held in any judicial proceeding to be unenforceable or
invalid or shall cease for any reason to be in full force and effect or any
Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary
Guarantor, shall deny or disaffirm its obligations under the Subsidiary
Guarantees issued thereunder; or

     (j)  any of the Security Documents ceases to be in full force and effect,
or any of the Security Documents ceases to give the holders of the Notes any of
the Liens purported to be created thereby, or any of the Security Documents is

writing that it has any further liability under any Security Document or gives
written notice to such effect (in each case other than in accordance with the
terms of this Indenture (including Section 14.01(b)) or the terms of the
Existing Credit Facility or the Security Documents (including the cessation of
effectiveness of any Security Document in connection with a release of all
collateral covered thereby in accordance with the terms of this Indenture, the
Existing Credit Facility, the Existing Senior Secured Note Indentures and such
Security Document) or unless waived by the requisite lenders under the Existing
Credit Facility if, after the waiver, the Company is in compliance with Section
4.12; provided that if a failure of the sort described in this clause (j) is
susceptible of cure, no Event of Default shall arise under this clause (j) with
respect thereto until 30 days after notice of such failure shall have been given
to the Company by the Trustee or the Holders of at least 25% in principal amount
of the then outstanding Notes issued under the Indenture.

     Section 6.02.  Acceleration. If an Event of Default (other than an Event of
Default specified in clause (g) or (h) of Section 6.01 that occurs with respect
to the

                                       81
<PAGE>

Company or any Subsidiary Guarantor) occurs and is continuing under this
Indenture, the Trustee or the Holders of at least 25% in aggregate principal
amount of the Notes then Outstanding, by written notice to the Company (and to
the Trustee if such notice is given by the Holders (the "Acceleration Notice")),
may, and the Trustee at the request of such Holders shall, declare the principal
of, premium, if any, and accrued but unpaid interest and Liquidated Damages, if
any, on all the Notes to be due and payable. Upon a declaration of acceleration,
such principal, premium, if any, and accrued interest and Liquidated Damages, if
any, shall be immediately due and payable. If an Event of Default specified in
clause (g) or (h) of Section 6.01 occurs with respect to the Company or any
Subsidiary Guarantor, the principal of, premium, if any, accrued interest and
Liquidated Damages, if any, on the Notes then Outstanding shall ipso facto
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any Holder.

     Section 6.03.  Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal or interest and Liquidated Damages on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

     The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder in exercising any right or remedy accruing upon an
Event of Default shall not impair the right or remedy or constitute a waiver of
or acquiescence in the Event of Default. All remedies are cumulative to the
extent permitted by law.

     Section  6.04. Waiver of Past Defaults. The Holders of at least a majority
in principal amount of the outstanding Notes, by written notice to the Company
and to the Trustee, may waive all past defaults and rescind and annul a
declaration of acceleration and its consequences under the Notes, if (i) all
existing Events of Default, other than the nonpayment of the principal of and
premium, if any, and interest and Liquidated Damages, if any, on such Notes that
have become due solely by such declaration of acceleration, have been cured or
waived and (ii) the rescission would not conflict with any judgment or decree of
a court of competent jurisdiction. Upon any such waiver, such Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured for every purpose of this Indenture; but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

     Section 6.05.  Control by Majority. The Holders of at least a majority in
aggregate principal amount of the Outstanding Notes may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee
or exercising any trust or power conferred on the Trustee. However, the Trustee
may refuse to follow any direction that conflicts with law or this Indenture,
that may involve the Trustee in personal liability, or that the Trustee
determines in good faith may be unduly prejudicial to the rights of Holders not
joining in the giving of such direction and may take any other action it deems
proper that is not inconsistent with any such direction received from the
Holders.

                                       82
<PAGE>

     Section 6.06. Limitation on Suits. A Holder may not pursue any remedy with
respect to this Indenture or the Notes unless:

     (a)  the Holder gives the Trustee written notice of a continuing Event of
Default;

     (b)  the Holders of at least 25% in aggregate principal amount of
Outstanding Notes make a written request to the Trustee to pursue the remedy;

     (c)  such Holder or Holders offer the Trustee security or indemnity
satisfactory to it against any loss, liability or expense;

     (d)  the Trustee does not comply with the request within 60 days after
receipt thereof and the offer of security or indemnity; and

     (e)  during such 60 day period, the Holders of at least a majority in
aggregate principal amount of the Outstanding Notes do not give the Trustee a
direction inconsistent with the request.

     Section 6.07. Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal, premium, if any, interest and Liquidated Damages, if any, on the
Note, on or after the respective due dates expressed in the Note, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of the Holder.

     Section 6.08. Collection Suit by Trustee. If an Event of Default specified
in Section 6.01(a) or (b) hereof occurs and is continuing, the Trustee is
authorized to recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor for the whole amount of
principal, premium, if any, and interest and Liquidated Damages, if any,
remaining unpaid on the Notes and interest on overdue principal and, to the
extent lawful, interest and Liquidated Damages, if any, and such further amount
as shall be sufficient to cover amounts due the Trustee under Section 7.08,
including the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

     Section 6.09. Trustee May File Proofs of Claim. The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary
or advisable in order to have the claims of the Trustee (including any claim for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Notes), its
creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses,

                                       83
<PAGE>

disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.08. To the extent that the payment of
any such compensation, expenses, disbursements and advances of the Trustee, its
agents and counsel, and any other amounts due the Trustee under Section 7.08 out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties which the
Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

     Section 6.10. Priorities. If the Trustee collects any money pursuant to
this Article or receives any money from the Collateral Agent as the distribution
of proceeds received upon realization of any Collateral, it shall pay out the
money in the following order:

     First: to the Trustee, its agents and attorneys for amounts due under
Section 7.08, including payment of all compensation, expense and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

     Second: to Holders for amounts due and unpaid on the Notes for principal,
premium, if any, interest and Liquidated Damages, if any, ratably, without
preference or priority of any kind, according to the amounts due and payable on
the Notes for principal, premium, if any, interest and Liquidated Damages,
respectively; and

     Third: to the Company or to such party as a court of competent jurisdiction
shall direct.

     The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 6.10 upon five Business Days prior notice to
the Company.

     Section 6.11. Undertaking for Costs. In any suit for the enforcement of any
right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section 6.06, or a suit by
Holders of more than 10% in aggregate principal amount of the then Outstanding
Notes.

     Section 6.12. Restoration of Rights and Remedies. If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture or any Note and such proceeding has been discontinued or abandoned for
any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case

                                       84
<PAGE>

the Company, any other obligor upon the Notes, the Trustee and the Holders
shall, subject to any determination in such proceeding, be restored severally
and respectively to their former positions hereunder, and thereafter all rights
and remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

     Section 6.13. Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

     Section 6.14. Waiver of Stay, Extension or Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury or other similar
law wherever enacted, now or at any time hereafter in force, that would prohibit
or forgive the Company from paying all or any portion of the principal of (or
premium, if any), interest or Liquidated Damages, if any, on the Notes
contemplated herein or in the Notes or that may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenant that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                   ARTICLE 7
                                  The Trustee

     Section 7.01. Certain Duties and Responsibilities. (a) Except during the
continuance of an Event of Default,

          (i)    the Trustee need perform only those duties that are
     specifically set forth in this Indenture and no others, and no implied
     covenants or obligations shall be read into this Indenture against the
     Trustee; and

          (ii)   in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. However,
     in the case of any such certificates or opinions which by any provision
     hereof are specifically required to be furnished to the Trustee, the
     Trustee shall examine the certificates and opinions to determine whether or
     not they conform to the requirements of this Indenture (but need not
     confirm or investigate the accuracy of mathematical calculations or other
     facts stated therein).

                                       85
<PAGE>

     (b)  In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
such person's own affairs.

     (c)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that (i) this paragraph does not
limit the effect of Section 7.01(a); (ii) the Trustee shall not be liable for
any error of judgment made in good faith by a Responsible Officer, unless it is
proved that the Trustee was negligent in ascertaining the pertinent facts; and
(iii) the Trustee shall not be liable with respect to any action it takes or
omits to take in good faith in accordance with a direction received by it
pursuant to Section 6.06.

     (d)  The Trustee may refuse to perform any duty or exercise any right or
power or expend or risk its own funds or otherwise incur any financial liability
unless it receives indemnity satisfactory to it against any loss, liability or
expense.

     (e)  Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of Sections 7.01
and 7.03.

     Section 7.02. Notice of Defaults. (a) Within 90 days after the occurrence
of any Default, the Trustee shall transmit by mail to all Holders, as their
names and addresses appear in the Register, notice of such Default hereunder
actually known to the Trustee unless such Default shall have been cured or
waived; provided, however, that, except in the case of a Default in the payment
of the principal of, premium (if any) or interest and Liquidated Damages, if
any, on, any Note, the Trustee may withhold such notice if and so long as the
board of directors, the executive committee or a trust committee of Responsible
Officers of the Trustee determines that the withholding of such notice is not
opposed to the interests of the Holders.

     (b)  The Trustee shall not be required to take notice or be deemed to have
notice or knowledge of any event or of any Default (except default in the
payment of monies to the Trustee which are required to be paid to the Trustee on
or before a specified date or within a specified time after receipt by the
Trustee of a notice or a certificate which was in fact received), unless the
Trustee shall receive from the Company or a Holder a notice stating that the
same has occurred and is continuing, and specifying the same, and in the absence
of such notice the Trustee may conclusively assume that the same does not exist,
except as aforesaid.

     Section 7.03. Certain Rights of Trustee. Subject to the provisions of
Section 7.01:

          (i)    the Trustee may conclusively rely and shall be protected in
     acting or refraining from acting upon any resolution, certificate,
     statement, instrument, opinion, report, notice, request, direction,
     consent, order, bond, note, other

                                       86
<PAGE>

     evidence of indebtedness or other paper or document believed by it to be
     genuine and to have been signed or presented by the proper party or
     parties;

          (ii)   any request or direction of the Company mentioned herein shall
     be sufficiently evidenced by a Company Request or a Company Order thereof,
     and any resolution of any Person's board of directors (or any committee
     thereof) shall be sufficiently evidenced if certified by an Officer of such
     Person as having been duly adopted and being in full force and effect on
     the date of such certificate;

          (iii)  whenever in the administration of this Indenture the Trustee
     shall deem it desirable that a matter be proved or established prior to
     taking, suffering or omitting any action hereunder, the Trustee (unless
     other evidence be herein specifically prescribed) may, in the absence of
     bad faith on its part, rely upon the Officer's Certificates of the Company;

          (iv)   the Trustee may consult with counsel of its selection and the
     written advice of such counsel or any Opinion of Counsel shall be full and
     complete authorization and protection in respect of any action taken,
     suffered or omitted by it hereunder in good faith and in reliance thereon;

          (v)    in case an Event of Default occurs and is continuing, the
     Trustee shall be under no obligation to exercise any of the rights or
     powers vested in it by this Indenture at the request or direction of any of
     the Holders pursuant to this Indenture, unless such Holders shall have
     offered to the Trustee security or indemnity satisfactory to it against any
     loss, liability or expense which might be incurred by it in compliance with
     such request or direction;

          (vi)   the Trustee shall not be bound to make any investigation into
     the facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,

          (vii)  the Trustee may execute any of the trusts or powers hereunder
     or perform any duties hereunder either directly or by or through agents or
     attorneys and the Trustee shall not be responsible for any misconduct or
     negligence on the part of any agent or attorney appointed with due care by
     it hereunder; and

          (viii) the rights, privileges, protections, immunities and benefits
     given to the Trustee, including, without limitation, its right to be
     indemnified, are extended to, and shall be enforceable by, the Trustee in
     each of its capacities hereunder, and to each agent, custodian and other
     Person employed to act hereunder.

     Section 7.04. Not Responsible for Recitals or Issuance of Notes. The
recitals contained herein and in the Notes, except the Trustee's certificates of
authentication, shall be taken as the statements of the Company, and neither the
Trustee nor any Authenticating Agent assumes any responsibility for their
correctness. The Trustee

                                       87
<PAGE>

makes no representations as to the validity or sufficiency of this Indenture or
of the Notes, except that the Trustee represents that it is duly authorized to
execute and deliver this Indenture, authenticate the Notes and perform its
obligations hereunder and that the statements made by it in a Statement of
Eligibility and Qualification on Form T-1 supplied to the Company in connection
with the registration of any Notes issued hereunder will be true and accurate
subject to the qualifications set forth therein. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of the Notes or the proceeds thereof.

     Section 7.05. Trustee's Disclaimer. The Trustee makes no representation as
to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company' use of the proceeds from the Notes, it shall not be
responsible for any statement in the offering memorandum for the Notes or in the
Indenture or the Notes (other than its certificate of authentication), the acts
of a prior Trustee hereunder, or the determination as to which beneficial owners
are entitled to receive any notices hereunder.

     Section 7.06. May Hold Notes. The Trustee, any Authenticating Agent, any
Paying Agent, any Registrar or any other agent of the Company, in its individual
or any other capacity, may become the owner or pledgee of Notes and, subject to
Section 7.09 and Section 7.14, may otherwise deal with the Company or its
Affiliates with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Registrar or such other agent.

     Section 7.07. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed in writing with the Company.

     (a)  to pay to the Trustee from time to time such compensation as the
Company and the Trustee shall from time to time agree in writing for all
services rendered by it hereunder (which compensation shall not be limited by
any provision of law in regard to the compensation of a trustee of an express
trust);

     (b)  to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any provision of this Indenture (including the reasonable compensation and the
expenses, advances and disbursements of its agents and counsel), except any such
expense, disbursement or advance as may be attributable to its negligence or bad
faith; and

     (c)  to indemnify the Trustee and any predecessor Trustee for, and to hold
it harmless against, any loss, damage, claims, liability or expense (including
taxes, other than taxes based on the income of the Trustee) incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this trust, including the reasonable costs and
expenses of defending itself against any claim

                                       88
<PAGE>

(whether asserted by the Company, a Holder or any other person) or liability in
connection with the exercise or performance of any of its powers or duties
hereunder.

     The Company' payment obligations pursuant to this Section 7.08 shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(g) or 6.01(h), the
expenses are intended to constitute expenses of administration under any
Bankruptcy Law.

     Section 7.09. Conflicting Interests. If the Trustee has or shall acquire a
conflicting interest within the meaning of the TIA, within 90 days the Trustee
shall either eliminate such conflicting interest, apply to the SEC for
permission to continue as Trustee with such conflicting interest, or resign, to
the extent and in the manner provided by, and subject to the provisions of, the
TIA and this Indenture. To the extent permitted by such Act, the Trustee shall
not be deemed to have a conflicting interest by virtue of being a trustee under
this Indenture with respect to Original Notes and Additional Notes, or a trustee
under any other indenture between the Company and the Trustee.

     Section 7.10. Corporate Trustee Required; Eligibility. (a) There shall at
all times be one (and only one) Trustee hereunder. The Trustee shall be a Person
that is eligible pursuant to the TIA to act as such and has a combined capital
and surplus of at least $100,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section 7.10
and to the extent permitted by the TIA, the combined capital and surplus of such
Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section
7.10, it shall resign immediately in the manner and with the effect hereinafter
specified in this Article.

     Section 7.11. Resignation and Removal; Appointment of Successor. (a) No
resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 7.12.

the Company. If the instrument of acceptance by a successor Trustee required by

the giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

     (c)  The Trustee may be removed at any time by Act of the Holders of a
majority in principal amount of the Outstanding Notes, delivered to the Trustee
and to the Company. If the instrument of acceptance by a successor Trustee

days after the giving of such notice of removal, the Trustee being removed may
petition any court of competent jurisdiction for the appointment of a successor

     If at any time:

          (i)   the Trustee shall fail to comply with Section 7.09 after written
     request therefor by the Company or by any Holder who has been a bona fide
     Holder for at least six months, or

          (ii)  the Trustee shall cease to be eligible under Section 7.10 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

          (iii) the Trustee shall become incapable of acting or shall be
     adjudged bankrupt or insolvent or a receiver of the Trustee or of its
     property shall be appointed or any public officer shall take charge or
     control of the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company may remove the Trustee, or (B) subject
to Section 6.11, any Holder who has been a bona fide Holder for at least six
months may, on behalf of itself and all others similarly situated, petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee or Trustees.

     (d)  If the Trustee shall resign, be removed or become incapable of acting,
or if a vacancy shall occur in the office of Trustee for any cause, the Company
shall promptly appoint a successor Trustee and shall comply with the applicable
requirements of Section 7.12. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
shall be appointed by Act of the Holders of a majority in principal amount of
the Outstanding Notes delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 7.12,
become the successor Trustee and to that extent supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner required by
Section 7.12, then, subject to Section 6.11, any Holder who has been a bona fide
Holder for at least six months may, on behalf of itself and all others similarly
situated, petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     (e)  The Company shall give notice of each resignation and each removal of
the Trustee and each appointment of a successor Trustee to all Holders in the
manner provided in Section 1.10. Each notice shall include the name of the
successor Trustee and the address of its Corporate Trust Office.

     Section 7.12. Acceptance of Appointment by Successor. (a) In case of the
appointment hereunder of a successor Trustee, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights,

                                       90
<PAGE>

powers, trusts and duties of the retiring Trustee; but, on the request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder.

     (b) Upon request of any such successor Trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts referred to above.

     (c) No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be qualified and eligible under
this Article 7.

     Section 7.13. Merger, Conversion, Consolidation or Succession to Business.
(a) Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article 7,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Notes shall have been authenticated, but
not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Notes so authenticated with the same effect as if
such successor Trustee had itself authenticated such Notes.

     Section 7.14. Preferential Collection of Claims Against the Company. (a) If
and when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Notes), the Trustee shall be subject to the provisions of the
TIA regarding the collection of claims against the Company (or any such other
obligor).

     Section 7.15. Appointment of Authenticating Agent. The Trustee may appoint
an Authenticating Agent acceptable to the Company to authenticate the Notes. Any
such appointment shall be evidenced by an instrument in writing signed by a
Responsible Officer, a copy of which instrument shall be promptly furnished to
the Company. Unless limited by the terms of such appointment, an Authenticating
Agent may authenticate Notes whenever the Trustee may do so. Each reference in
this Indenture to authentication (or execution of a certificate of
authentication) by the Trustee includes authentication (or execution of a
certificate of authentication) by such Authenticating Agent. An Authenticating
Agent has the same rights as any Registrar, Paying Agent or agent for service of
notices and demands.

Company, the Trustee and (if applicable) any Subsidiary Guarantor may amend or
supplement this Indenture or the Notes with the written consent of the Holders

                                       93
<PAGE>

of the Holders of not less than a majority in aggregate principal amount of the
Outstanding Notes.

     (b)  Notwithstanding the provisions of this Section 9.02, without the

     outstanding Notes the consent of whose Holders is necessary for waiver of
     compliance with provisions of the Indenture or for waiver of Defaults,

          (ix)   modify or change any provision of the Indenture affecting the
     ranking of the Notes or the Subsidiary Guarantees in a manner adverse to

          (xi)   directly or indirectly release the Liens created by the
     Security Documents on all or substantially all the Collateral (other than

<PAGE>

     the consent of the requisite lenders under the Existing Credit Facility if,
     after such consent, the Company is in compliance with Section 4.12).

     (c)  It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

     (d)  After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders of each Note affected
thereby, with a copy to the Trustee, a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to mail such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any supplemental indenture or the effectiveness of any such amendment,
supplement or waiver.

     Section 9.03. Execution of Amendments, Supplements or Waivers. The Trustee
shall sign any amendment, supplement or waiver authorized pursuant to this
Article 9 if the amendment, supplement or waiver does not adversely affect the
rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver, the Trustee shall be entitled to receive, and
shall be fully protected in relying upon, an Officer's Certificate and an
Opinion of Counsel to the effect that the execution of such amendment,
supplement or waiver has been duly authorized, executed and delivered by the
Company and that such amendment, supplement or waiver is a valid and binding
agreement of the Company, enforceable against it in accordance with its terms
(subject to customary exceptions).

     Section 9.04. Revocation and Effect of Consents. (a) Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder is a
continuing consent by the Holder and every subsequent Holder of that Note or any
Note that evidences all or any part of the same debt as the consenting Holder's
Note, even if notation of the consent is not made on any Note. Subject to the
following paragraph of this Section 9.04, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note by notice to the Trustee or the
Company received by the Trustee or the Company, as the case may be, before the
date on which the Trustee receives an Officer's Certificate certifying that the
Holders of the requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver. The
Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver as set forth in Section 1.08.

     (b) After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (i)
through (viii) of Section 9.02(b). In that case, the amendment, supplement or
waiver shall bind each Holder of a Note who has consented to it and every
subsequent Holder of such Note or any Note that evidences all or any part of the
same debt as the consenting Holder's Note.

     Section 9.05. Conformity with TIA. (a) Every amendment or supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the TIA as then in effect.

     Section 9.06. Notation on or Exchange of Notes. (a) If an amendment,
supplement or waiver changes the terms of a Note, the Trustee shall (if required
by the Company and in accordance with the specific direction of the Company)
request the Holder to deliver its Note to the Trustee. The Trustee shall (if
required by the Company and in accordance with the specific written direction of
the Company) place an appropriate notation on the Note about the changed terms
and return it to the Holder. Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms. Failure to make
the appropriate notation or issue a new Note shall not affect the validity and
effect of such amendment, supplement or waiver.

other Note.

New York City time on any Redemption Date, the Company shall deposit with the

     (b)  Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 7.08 and, if money shall

                       Defeasance and Covenant Defeasance

     Section 12.01. Option of the Company to Effect Defeasance or Covenant
Defeasance. The Company may at its option by a Board Resolution, at any time,
elect to have either Section 12.02 or Section 12.03 applied to the Outstanding
Notes upon compliance with the conditions set forth below in this Article 12.

                                      100
<PAGE>

     Section 12.02. Legal Defeasance and Discharge. Upon the exercise by the
Company under Section 12.01 of the option applicable to this Section 12.02, the
Company shall be deemed to have been discharged from any and all Obligations
with respect to all Outstanding Notes (and any Subsidiary Guarantor will be
discharged from any and all Obligations in respect of its Subsidiary Guarantee)
on the date which is the 123rd day after the deposit referred to in Section
12.04(a); provided that all of the conditions set forth below are satisfied
(hereinafter, "Legal Defeasance"). For this purpose, such Legal Defeasance means
that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be "outstanding" only for the purposes of Section 12.05 hereof and the
other Sections of this Indenture referred to in clauses (i) and (ii) of this
Section 12.02, and to have satisfied all its other obligations under such Notes
and this Indenture (and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging the same), except for
the following provisions which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of Outstanding Notes to receive
solely from the trust fund described in Section 12.04 hereof, and as more fully
set forth in such Section, payments in respect of the principal of, premium, if
any, and interest and Liquidated Damages on such Notes when such payments are
due, (ii) the obligations of the Company with respect to such Notes under
Sections 1.06, 2.03, 3.03, 3.04, 3.05, 3.06, 3.13, 3.14, 4.01, 4.02, 4.03 and
12.05 hereof, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder, including, without limitation, the Trustee's rights under
Section 7.08 hereof, and the obligations of the Company in connection therewith
and with this Article 12. Subject to compliance with this Article 12, the
Company may exercise its option under this Section 12.02 notwithstanding the
prior exercise of its option under Section 12.03 hereof with respect to the
Notes.

     Section 12.03. Covenant Defeasance. Upon the exercise by the Company under
Section 12.01 of the option applicable to this Section 12.03, the Company shall
be released from its obligations under the covenants contained in Sections 4.06
through Section 4.18, Section 4.22, Article 14 and clause (iv) of Section
5.01(a) hereof with respect to the Outstanding Notes and no Default under
Section 6.01(e), (f) and (g) shall thereafter constitute a Default or Event of
Default on the date which is the 123rd day after the deposit referred to in
Section 12.04(a); provided that all of the conditions set forth below are
satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter
be deemed not Outstanding for the purposes of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed Outstanding for
all other purposes hereunder. For this purpose, such Covenant Defeasance means
that, with respect to the Outstanding Notes, the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in
any such covenant to any other provision herein or in any other document and
such omission to comply shall not constitute a Default or an Event of Default
under Section 6.01(c) or (d), but, except as specified above, the remainder of
this Indenture and such Notes shall be unaffected thereby.

     Section 12.04. Conditions to Legal or Covenant Defeasance. The following
shall be the conditions to application of either Section 12.02 or Section 12.03
to the Outstanding Notes:

     (a)  the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and principal
in respect thereof in accordance with their terms will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay (i) the principal of, premium, if any, and accrued interest and
Liquidated Damages, if any, on the Notes when such payments are due in
accordance with the terms of this Indenture and the Notes or (ii) in the case of
Legal Defeasance, accrued interest and Liquidated Damages, if any, on the Notes
through a scheduled redemption date and the principal of, and premium on the
Notes on such redemption date; provided that, at the time of deposit, the
Company irrevocably authorize the Trustee to issue a timely notice of redemption
and to take such other steps reasonably requested by the Trustee to ensure that
such redemption will be effectuated;

     (b)  in the case of an election under Section 12.02, the Company has
delivered to the Trustee (i) either (x) an Opinion of Counsel to the effect that
Holders will not recognize income, gain or loss for Federal income tax purposes
as a result of the exercise by the Company of its option under this Article 12
and will be subject to Federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred, which Opinion of Counsel must be
based upon (and accompanied by a copy of) a ruling of the Internal Revenue
Service to the same effect unless there has been a change in applicable Federal
income tax law after the date of this Indenture such that a ruling is no longer
required or (y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of Counsel and
(ii) an Opinion of Counsel to the effect that, as a result of the creation of
the defeasance trust, the Company will not be required to register under the
Investment Company Act of 1940 and after the passage of 123 days following the
deposit, the trust fund will not be subject to the effect of Section 547 of the
United States Bankruptcy Code or Section 15 of the New York Debtor and Creditor
Law or any comparable provision of applicable law;

     (c)  in the case of an election under Section 12.03, the delivery by the
Company to the Trustee of (i) an Opinion of Counsel to the effect that, among
other things, the Holders will not recognize income, gain or loss for Federal
income tax purposes as a result of such deposit and defeasance and will be
subject to Federal income tax on the same amount and in the same manner and at
the same times as would have been the case if such deposit and defeasance had
not occurred and (ii) an Opinion of Counsel to the effect that, as a result of
the creation of the defeasance trust, the Company will not be required to
register under the Investment Company Act of 1940 and after the passage of 123
days following the deposit, the trust fund will not be subject to the effect of
Section 547 of the United States Bankruptcy Code or Section 15 of the New York
Debtor and Creditor Law or any comparable provision of applicable law;

                                      102
<PAGE>

     (d)  immediately after giving effect to such deposit on a pro forma basis,
no Event of Default, or event that after the giving of notice or lapse of time
or both would become an Event of Default, shall have occurred and be continuing
on the date of such deposit or during the period ending on the 123rd day after
the date of such deposit, and such deposit shall not result in a breach or
violation of, or constitute a default under, any other agreement or instrument
to which the Company is a party or by which the Company is bound;

     (e)  if at such time the Notes are listed on a national securities
exchange, the Company has delivered to the Trustee an Opinion of Counsel to the
effect that the Notes will not be delisted as a result of such deposit,
defeasance and discharge;

     (f)  the Company shall have delivered to the Trustee Officer's Certificates
stating that the deposit made by the Company pursuant to its election under
Sections 12.02 or 12.03 was not made by the Company with the intent of
preferring the Holders over the other creditors of the Company with the intent
of defeating, hindering, delaying or defrauding creditors of the Company or
others; and

     (g)  the Company shall have delivered to the Trustee Officer's Certificates
and an Opinion of Counsel, each stating that all conditions precedent provided
for relating to either the Legal Defeasance under Section 12.02 or the Covenant
Defeasance under Section 12.03 (as the case may be) have been complied with as
contemplated by this Section 12.04.

     Section 12.05. Deposited Money and Government Securities to Be Held in
Trust; Other Miscellaneous Provisions. Subject to Section 12.06, all money and
U.S. Government Obligations (including the proceeds thereof) deposited with the
Trustee pursuant to Section 12.04 in respect of the Outstanding Notes shall be
held in trust and applied by the Trustee, in accordance with the provisions of
such Notes and this Indenture, to the payment, either directly or through any
Paying Agent (including the Company acting as Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal of, premium, if any, and interest and Liquidated
Damages, but such money need not be segregated from other funds except to the
extent required by law.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the money or U.S. Government
Obligations deposited pursuant to Section 12.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the Outstanding Notes.

     Anything in this Article 12 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or U.S. Government Obligations held by it as provided in
Section 12.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
12.04(a) hereof), are in excess of the amount thereof

                                      103
<PAGE>

which would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

     Section 12.06. Repayment to Company. Any money deposited with the Trustee
or any Paying Agent, or then held by the Company, in trust for the payment of
the principal of, premium, if any, or interest and Liquidated Damages on any
Note and remaining unclaimed for two years after such principal, premium, if
any, or interest and Liquidated Damages has become due and payable shall be paid
to the Company on its written request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as trustee thereof, shall thereupon
cease; provided, however, that the Trustee or such Paying Agent, before being
required to make any such repayment, shall at the expense of the Company cause
to be published once, in The New York Times and The Wall Street Journal
(national edition), notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such notification or publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

     Section 12.07. Reinstatement. If the Trustee or Paying Agent is unable to
apply any money or U.S. Government Obligations in accordance with Section 12.02
or 12.03, as the case may be, by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the obligations of the Company under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section 12.02 or 12.03 until such time as the Trustee or Paying Agent is
permitted to apply all such amounts in accordance with Section 12.02 or 12.03
hereof, as the case may be; provided, however, that, if the Company makes any
payment of principal of, premium, if any, or interest and Liquidated Damages on
any Note following the reinstatement of its Obligations, the Company shall be
subrogated to the rights of the Holder of such Note to receive such payment from
the amounts held by the Trustee or Paying Agent.

                              Subsidiary Guarantees

     Section 13.01. The Guarantees. (a) Subject to the provisions of this
Article 13, each Subsidiary Guarantor hereby irrevocably and unconditionally
guarantees, jointly and severally, the full and punctual payment (whether at
Stated Maturity, upon acceleration, optional redemption, upon repurchase
following a Change of Control Offer or an Asset Sale Offer or otherwise) of the
principal of and premium, if any, and interest and Liquidated Damages, if any,
on, and all other amounts payable under, each Note provided for under this
Indenture, and the full and punctual payment of all other amounts payable by the
Company under this Indenture. Upon failure by the Company to pay punctually any
such amount, each Subsidiary Guarantor shall forthwith on demand pay the amount
not so paid at the place and in the manner specified in this Indenture.

                                      104
<PAGE>

     Section 13.02. Guarantee Unconditional. The obligations of the Subsidiary
Guarantors hereunder shall be unconditional and absolute and, without limiting
the generality of the foregoing, shall, to the fullest extent permitted by law,
not be released, discharged or otherwise affected by:

     (a)  any extension, renewal, settlement, compromise, waiver or release in
respect of any obligation of the Company under this Indenture or any Note, by
operation of law or otherwise;

     (b)  any modification or amendment of or supplement to this Indenture or
any Note; provided that any such modification which increases the obligations of
each Subsidiary Guarantor hereunder shall not be effective as to such Subsidiary
Guarantor without its consent;

     (c)  any release, impairment, non-perfection or invalidity of any direct or
indirect security for any obligation of the Company or any Subsidiary Guarantor
hereunder;

     (d)  any change in the corporate existence, structure or ownership of the
Company, or any insolvency, bankruptcy, reorganization or other similar
proceeding affecting the Company or its assets or any resulting release or
discharge of any obligation of the Company contained in this Indenture or any
Note;

     (e)  the existence of any claim, set-off or other rights which the
Subsidiary Guarantors may have at any time against the Company, the Trustee or
any other Person, whether in connection with this Indenture or any unrelated
transactions, provided that nothing herein shall prevent the assertion of any
such claim by separate suit or compulsory counterclaim;

     (f)  any invalidity or unenforceability relating to or against the Company
for any reason of this Indenture or any Note, or any provision of applicable law
or regulation purporting to prohibit the payment by the Company of the principal
of or interest and Liquidated Damages on any Note or any other amount payable by
the Company under this Indenture; or

     (g)  any other act or omission to act or delay of any kind by the Company,
the Trustee or any other Person or any other circumstance whatsoever which
might, but for the provisions of this paragraph, constitute a legal or equitable
discharge of or defense to such Subsidiary Guarantor's obligations hereunder.

     Section 13.03. Discharge; Reinstatement. The Subsidiary Guarantors'
obligations hereunder shall remain in full force and effect until the principal
of, premium, if any, and interest and Liquidated Damages, if any, on the Notes
and all other amounts payable by the Company under this Indenture shall have
been paid in full. If at any time any payment of the principal of, premium, if
any, or interest and Liquidated Damages, if any, on any Note or any other amount
payable by the Company under this Indenture is rescinded or must be otherwise
restored or returned upon the insolvency, bankruptcy or reorganization of the
Company or otherwise, the Subsidiary Guarantors'

                                      105
<PAGE>

obligations hereunder with respect to such payment shall be reinstated as though
such payment had been due but not made at such time.

     Section 13.04. Waiver by the Subsidiary Guarantors. The Subsidiary
Guarantors irrevocably waive acceptance hereof, presentment, demand, protest and
any notice not provided for herein, as well as any requirement that at any time
any action be taken by any Person against the Company or any other Person.

     Section 13.05. Subrogation and Contribution. Upon making any payment with
respect to any obligation of the Company under this Article 13, the Subsidiary
Guarantor making such payment shall be subrogated to the rights of the payee
against the Company with respect to such obligation; provided that such
Subsidiary Guarantor shall not enforce either (i) any right to receive payment
by way of subrogation against the Company or against any direct or indirect
security for such obligation, or any other right to be reimbursed, indemnified
or exonerated by or for the account of the Company in respect thereof or (ii)
any right to receive payment, in the nature of contribution or for any other
reason, from any other Subsidiary Guarantor with respect to such payment, in
each case so long as any amount payable by the Company hereunder or under the
Notes remains unpaid.

     Section 13.06. Stay of Acceleration. If acceleration of the time for
payment of any amount payable by the Company under this Indenture or the Notes
is stayed upon the insolvency, bankruptcy or reorganization of the Company, all
such amounts otherwise subject to acceleration under the terms of this Indenture
shall nonetheless be payable by the Subsidiary Guarantors hereunder forthwith on
demand by the Trustee or the Holders.

     Section 13.07. Limits of Guarantees. Notwithstanding anything to the
contrary in this Article 13, each Subsidiary Guarantor, and by its acceptance of
Notes, each Holder, hereby confirms that it is the intention of all such parties
that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
conveyance under applicable fraudulent conveyance provisions of the United
States Bankruptcy Code or any comparable provision of state law. To effectuate
the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of such Subsidiary Guarantor under
its Subsidiary Guarantee and this Article 13 shall be limited to the maximum
amount that would not render such Subsidiary Guarantor's obligations subject to
avoidance under applicable fraudulent conveyance provisions of the United States
Bankruptcy Code or any comparable provision of state law.

     Section 13.08. Execution and Delivery of Note Guarantee. To evidence its
Subsidiary Guarantee set forth in Section 13.01, each Subsidiary Guarantor
hereby agrees that this Indenture (or a supplemental indenture in the form of
Exhibit B hereto) shall be executed on behalf of such Subsidiary Guarantor by
one of its Officers.

     The signature of an Officer of a Subsidiary Guarantor on the Indenture
shall bind such Subsidiary Guarantor, notwithstanding that such individual has
ceased to hold such office prior to the authentication and delivery of any Note
or did not hold such office at the date of such Note.

                                      106
<PAGE>

     The delivery of any Note by the Trustee, after the authentication thereof
hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth
in this Indenture on behalf of the Subsidiary Guarantors.

                                  ARTICLE 14
                              Security Arrangements

     Section 14.01. Security. (a) In order to secure the Indenture Obligations
equally and ratably with the Existing Credit Facility Obligations and
Obligations in respect of the Existing Senior Secured Notes and, with respect to
certain of the Collateral, the Existing ARCO Chemical Debt, the Company will,
and will cause each of its Restricted Subsidiaries named in any Existing
Security Document as a party thereto, to execute and deliver to the Collateral
Agent prior to the Issue Date each Existing Security Document to which it is a
party. The Company and its Restricted Subsidiaries shall comply with all
covenants and agreements contained in the Security Documents the failure to
comply with which would have a material and adverse effect on the Liens
purported to be created thereby, unless such failure to comply is waived by the
requisite lenders under the Existing Credit Facility if, after that waiver, the
Company is in compliance with Section 4.12.

     (b)  The Trustee and each holder of each Note by its acceptance of that
Note acknowledges and agrees that:

             (i)    this Indenture, as originally executed and delivered by the
     parties hereto, does not create any Lien on any property or securities
     which secures the Indenture Obligations or this Indenture;

             (ii)   the Existing Security Documents, when executed and delivered
     by the parties thereto, will comply with the provisions of Section 4.12;

             (iii)  the Existing Security Documents provide, and any Security
     Document that becomes effective after the Issue Date, may provide, that the
     Liens created thereby or thereunder automatically will be released and
     extinguished with respect to any property or security that is transferred
     or otherwise disposed of in accordance with the terms of the Existing
     Credit Facility, including any property or security that is the subject of
     a Major Asset Sale and is transferred to a Subject Asset Transferee;

             (iv)   without the necessity of any consent of or notice to the
     Trustee or any holder of Indenture Obligations, the Company and the
     Collateral Agent may amend, modify, supplement or terminate any Security
     Document as long as the Company remains in compliance with Section 4.12;

             (v)    as among the Trustee and the holders of Indenture
     Obligations and the lenders under the Existing Credit Facility and the
     Collateral Agent, those lenders and the Collateral Agent will have the sole
     ability to control and obtain

                                      107
<PAGE>

     remedies with respect to all Collateral (including on sale or liquidation
     of any Collateral after acceleration of the Notes, the Existing Senior
     Secured Notes, the Existing Credit Facility Obligations or the Existing
     ARCO Chemical Debt) without the necessity of any consent of or notice to
     the Trustee or any such holder;

             (vi)   any or all Liens granted under the Security Documents for
     the benefit of the Holders will be automatically released, without the
     necessity of any consent of the Trustee or any Holders, upon a release of
     such Lien or Liens pursuant to the terms of the Security Documents and the
     Existing Credit Facility or if such release is approved by the requisite
     lenders under the Existing Credit Facility.

             (vii)  the relative rights of the holders of Indenture Obligations
     and the holders of Indebtedness or other obligations secured by Liens on
     the Collateral are governed by, and are subject to the terms and conditions
     of, the Security Documents and not this Indenture; and

             (viii) without the necessity of any consent of or notice to the
     Trustee or any holder of Indenture Obligations, the Company may, on behalf
     of itself or any of its Restricted Subsidiaries, request and instruct the
     Collateral Agent to, on behalf of each secured party under the Security
     Documents, (A) execute and deliver to the Company, for the benefit of any
     Person, such release documents as the Company may reasonably request, of
     all liens and security interests held by the Collateral Agent in such
     assets, and such Person shall be entitled to rely conclusively on such
     release document, and (B) deliver any such assets in the possession of the
     Collateral Agent to the Company.

     Section 14.02. Notice of Payment, Discharge or Defeasance. The Trustee and
each Holder, by its acceptance of a Note, agree that upon the payment in full or
discharge pursuant to Article 11 of the Indenture Obligations, the Trustee shall
without notice to or consent of any Holder, upon the written request of the
Company, certify to the Collateral Agent, in writing, that the Indenture

                           LYONDELL CHEMICAL COMPANY

                      9 1/2% Senior Secured Note due 2008

         (1)  Principal and Interest. The Company agrees to pay the principal of
this Note on December 15, 2008.

         The Company agrees to pay interest on the principal amount of this Note
on each Interest Payment Date, as set forth below, at the rate of 9 1/2% per
annum.

         Interest will be payable semi-annually (to the Holders of record of the
Notes (or any predecessor Notes) at the close of business on the Regular Record
Date immediately preceding the Interest Payment Date) on each Interest Payment
Date, commencing June 15, 2002.

         [The Holder of this Note is entitled to the benefits of the
Registration Rights Agreement, dated December 4, 2001, among the Company, the
Subsidiary Guarantors party thereto and the Initial Purchasers named therein
(the "Registration Rights Agreement"). In the event that (i) the Company or the
Subsidiary Guarantors fail to file an Exchange Offer Registration Statement with
the SEC on or prior to the 90th day after the Issue Date, (ii) if the Exchange
Offer Registration Statement is not declared effective by the SEC on or prior to
the 210th day after the Issue Date, (iii) if the Exchange Offer is not
consummated on or before the 30th business day after the Exchange Offer
Registration Statement is declared effective, (iv) the Company and the
Subsidiary Guarantors are obligated to file the Shelf Registration Statement and
fail to file the Shelf Registration Statement with the SEC on or prior to the
30th day after such filing obligation arises, (v) the Company and the Subsidiary
Guarantors are obligated to file a Shelf Registration Statement and the Shelf
Registration Statement is not declared effective on or prior to the 60th day
after the obligation to file a Shelf Registration Statement arises, or (vi) if
the Exchange Offer Registration Statement or the Shelf Registration Statement,
as the case may be, is declared effective but thereafter ceases to be effective
or useable in connection with resales of the Notes during the periods specified
in the Registration Rights Agreement, for such time of non-effectiveness or
non-usability (each, a "Registration Default"), the Company and the Subsidiary
Guarantors agree to pay to the Holder of this Note, if affected thereby,
liquidated damages ("Liquidated Damages") in an amount equal to $0.05 per week
per $1,000 in principal amount of this Note for each week or portion thereof
that the Registration Default continues for the first 90 day period immediately
following the occurrence of such Registration Default. The amount of the
Liquidated Damages shall increase by an additional $0.05 per week per $1,000 in
principal amount of Notes with respect to each subsequent 90 day period until
all Registration Defaults have been cured, up to a maximum amount of Liquidated
Damages of $0.25 per week per $1,000 in principal amount of Notes. The Company
and the Subsidiary Guarantors shall not be required to pay Liquidated Damages
for more than one Registration Default at any given time.

                                      A-4
<PAGE>

Following the cure of all Registration Defaults, the accrual of Liquidated
Damages will cease.]/2/

         Interest on this Note will accrue from the most recent date to which
interest has been paid [on this Note or the Note surrendered in exchange
herefor]/3/ or, if no interest has been paid, from December 4, 2001; provided
that, if there is no existing default in the payment of interest and if this
Note is authenticated between a Regular Record Date referred to on the face
hereof and the next succeeding Interest Payment Date, interest shall accrue from
such Interest Payment Date. Interest will be computed on the basis of a 360-day
year of twelve 30-day months.

         The Company shall pay interest on overdue principal and premium, if
any, and interest on overdue installments of interest and Liquidated Damages, to
the extent lawful, at a rate per annum equal to 1% per annum in excess of the
rate of interest applicable to the Notes.

         (2) Method of Payment. The Company will pay interest (except defaulted
interest) on the principal amount of the Notes on each June 15 and December 15
to the Persons who are Holders (as reflected in the Register at the close of
business on the June 1 and December 1 immediately preceding the Interest Payment
Date), in each case, even if the Note is canceled on registration of transfer or
registration of exchange after such Regular Record Date; provided that, with
respect to the payment of principal, the Company will make payment to the Holder
that surrenders this Note to any Paying Agent on or after December 15, 2008.

         The Company will pay principal, premium, if any, and interest and
Liquidated Damages, if any, in money of the United States that at the time of
payment is legal tender for payment of public and private debts. Payments
(including principal, premium, if any, and interest and Liquidated Damages, if
any) in respect of the Notes represented by the Global Notes, the Holders of
which have given wire transfer instructions on or prior to the relevant record
date, shall be made by wire transfer of immediately available funds to the
accounts specified by the Global Note Holder. With respect to Physical Notes,
the Company will make all payments of principal, premium, if any, and interest
and Liquidated Damages, if any, at the office or agency maintained by the
Company for such purposes in The City of New York or, at the Company's option,
by mailing a check to each such Holder's registered address. If a payment date
is a date other than a Business Day, payment may be made at that place on the
next succeeding day that is a Business Day and no interest shall accrue for the
intervening period.

         (3) Paying Agent and Registrar. Initially, the Trustee will act as
Paying Agent and Registrar. The Company may change any Paying Agent or Registrar
upon written notice thereto. The Company, any Subsidiary or any Affiliate of any
of them may act as Paying Agent, Registrar or co-registrar.

<PAGE>

         (4) Indenture; Limitations. The Company issued the Notes under an
Indenture dated as of December 4, 2001 (the "Indenture"), among the Company, the
Subsidiary Guarantors and The Bank of New York, as trustee (the "Trustee").
Capitalized terms herein are used as defined in the Indenture unless otherwise
indicated. The terms of the Notes include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(the "TIA"). The Notes are subject to all such terms, and Holders are referred
to the Indenture and the TIA for a statement of all such terms. To the extent
permitted by applicable law, in the event of any inconsistency between the terms
of this Note and the terms of the Indenture, the terms of the Indenture shall
control.

         The Notes are secured senior obligations of the Company. The Indenture
limits the initial aggregate principal amount of the Notes to $393,000,000 but
permits the issuance of Additional Notes subject to compliance with certain
conditions and covenants contained in the Indenture and except as may be limited
by applicable law.

         (5) Optional Redemption. The Notes may be redeemed at the option of the
Company, in whole or in part, at any time and from time to time, on or after
December 1, 2005, at the following Redemption Prices (expressed in percentages
of principal amount on the relevant Redemption Date), plus accrued and unpaid
interest and Liquidated Damages, if any, to the Redemption Date, if redeemed
during the 12-month period commencing December 15 of each of the years set forth
below:

            Year                                       Redemption Price

2005.................................                      104.750%

2006.................................                      102.375%

2007 and thereafter..................                      100.000%

         If less than all the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not so listed, on a pro rata basis, by lot
or by such method as the Trustee shall deem fair and appropriate; provided that
no Notes of $1,000 or less shall be redeemed in part.

         Notices of redemption shall be mailed by first class mail at least 30
but not more than 60 days before the redemption date to each Holder of Notes to
be redeemed at its registered address. Notices of redemption may not be
conditional. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest and
Liquidated Damages, if any, cease to accrue on Notes or portions of them called
for redemption.

                                      A-6
<PAGE>

         (6)  Repurchase upon a Change in Control and Sale of Assets. Upon the
occurrence of (a) a Change in Control, each Holder shall have the right to
require that the Company repurchase such Holder's Notes at a purchase price in
cash equal to 101% of the principal amount thereof on the date of purchase, plus
accrued and unpaid interest and Liquidated Damages, if any, to the date of
purchase and (b) an Asset Sale, the Company may be obligated to make an offer to
purchase on a pro rata basis from the Holders the Notes with the Excess Proceeds
of such Asset Sales at a purchase price equal to 100% of the principal amount of
such Notes plus accrued interest and Liquidated Damages, if any, to the date of
purchase.

         (7)  Denominations; Transfer; Exchange. The Notes are in fully
registered form without coupons, in denominations of $1,000 and any integral
multiples of $1,000. A Holder may register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture.

         (8)  Persons Deemed Owners. A Holder may be treated as the owner of a
Note for all purposes.

         (9)  Unclaimed Money. If money for the payment of principal, premium,
if any, or interest and Liquidated Damages, if any, remains unclaimed for two
years, the Trustee and the Paying Agent will pay the money back to the Company
at its written request. After that, Holders entitled to the money must look to
the Company for payment, unless an abandoned property law designates another
Person, and all liability of the Trustee and such Paying Agent with respect to
such money shall cease.

         (10) Discharge Prior to Redemption or Maturity. If the Company
irrevocably deposits, or causes to be deposited, with the Trustee money or U.S.
Government Obligations sufficient to pay the then outstanding principal of and
premium, if any, and accrued interest and Liquidated Damages on the Notes (a) to
redemption or maturity, the Company will be discharged from the Indenture and
the Notes, except in certain circumstances for certain sections thereof, and (b)
to redemption or maturity, the Company will be discharged from certain covenants
set forth in the Indenture.

         (11) Amendment; Supplement; Waiver. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the Notes then
Outstanding, and any existing Default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount of the Notes then Outstanding. Without notice to or the consent of any
Holder, the parties thereto may amend the Indenture or the Notes to the extent
set forth in the Indenture.

         (12) Restrictive Covenants. The Indenture contains certain covenants,
including, without limitation, covenants with respect to the following matters:
(i) Indebtedness; (ii) Restricted Payments; (iii) distributions from Restricted
Subsidiaries and Joint Ventures; (iv) sales of assets; (v) transactions with
Affiliates; (vi) Liens; (vii) no amendment to subordination provisions; (viii)
repurchase of Notes upon a Change in

                                      A-7
<PAGE>

Control; (ix) Sale and Leaseback Transactions; (x) Subsidiary Guarantees; and
(xi) consolidation, merger and sale of assets. Within 120 days after the end of
each fiscal year, the Company must report to the Trustee on compliance with such
limitations.

         (13) Successor Persons. When a successor person or other entity (other
than a Subsidiary of the Company) assumes all the obligations of its predecessor
under the Notes and the Indenture, the predecessor person will be released from
those obligations.

         (14) Remedies for Events of Default. If an Event of Default (other than
an Event of Default specified in Section 6.01(g) or (h) of the Indenture that
occurs with respect to the Company or a Subsidiary Guarantor) occurs and is
continuing under this Indenture, then in every such case the Trustee or the
Holders of at least 25% in aggregate principal amount of the Outstanding Notes,
by written notice to the Company (and to the Trustee if such notice is given by
the Holders), may, and the Trustee at the written request of such Holders shall,
declare the principal of, premium, if any, and accrued interest and Liquidated
Damages, if any, on all of the Outstanding Notes to be immediately due and
payable. Upon a declaration of acceleration, such principal of, premium, if any,
and accrued interest and Liquidated Damages, if any, shall be immediately due
and payable. If an Event of Default specified in Section 6.01(g) or (h) of the
Indenture occurs with respect to the Company or a Subsidiary Guarantor, the
principal of, premium, if any, and accrued interest and Liquidated Damages, if
any, on the Outstanding Notes shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder. The Holders of at least a majority in aggregate principal amount of the
Outstanding Notes by written notice to the Company and to the Trustee, may waive
all past defaults and rescind and annul a declaration of acceleration and its
consequences if (1) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any, and interest and Liquidated Damages, if any,
on the Notes that have become due solely by such declaration of acceleration,
have been cured or waived and (2) the recission would not conflict with any
judgment or decree of a court of competent jurisdiction.

         Holders may not enforce the Indenture, the Notes or the Subsidiary
Guarantees except as provided in the Indenture. The Trustee may require security
or indemnity satisfactory to it before it enforces the Indenture, the Notes or
the Subsidiary Guarantees. The Holders of at least a majority in aggregate
principal amount of the Notes then Outstanding may direct the Trustee in the
exercise of any trust or power in accordance with the terms of the Indenture.

         (15) Security. In order to secure the Indenture Obligations, the
Company and certain of its Restricted Subsidiaries have entered into the
Security Documents. The Indenture Obligations shall be secured by Liens on the
Collateral in accordance with the terms and provisions of the Security
Documents. The Indenture requires that Holders of the Notes be granted a lien
equally and ratably with any lien granted on additional assets to secure the
holders of Existing Credit Facility Obligations subsequent to the Issue Date.
Each Holder of this Note, by accepting the same, agrees that (i) the Existing
Security Documents provide, and any Security Document that becomes effective
after the Issue Date, may provide, that the Liens created thereby or thereunder
automatically will be released and extinguished with respect to any property or
security that is transferred or

                                      A-8
<PAGE>

otherwise disposed of in accordance with the terms of the Existing Credit
Facility, including any property or security that is the subject of a Major
Asset Sale and is transferred to a Subject Asset Transferee; (ii) without the
necessity of any consent of or notice to the Trustee or any holder of Indenture
Obligations, the Company and the Collateral Agent may amend, modify, supplement
or terminate any Security Document as long as the Company remains in compliance
with the Indenture; (iii) as among the Trustee and the holders of Indenture
Obligations and the lenders under the Existing Credit Facility and the
Collateral Agent, those lenders and the Collateral Agent will have the sole
ability to control and obtain remedies with respect to all Collateral (including
on sale or liquidation of any Collateral after acceleration of the Notes, the
Existing Senior Secured Notes, the Existing Credit Facility Obligations or the
Existing ARCO Chemical Debt) without the necessity of any consent of or notice
to the Trustee or any such holder; (iv) any or all Liens granted under the
Security Documents for the benefit of the Holders will be automatically
released, without the necessity of any consent of the Trustee or the Holders,
upon a release of such Lien or Liens pursuant to the terms of the Security
Documents and the Existing Credit Facility or if such release is approved by the
requisite lenders under the Existing Credit Facility; (v) the relative rights of
the holders of Indenture Obligations and the holders of Indebtedness or other
obligations secured by Liens on the Collateral are governed by, and are subject
to the terms and conditions of, the Security Documents and not this Indenture;
and (vi) without the necessity of any consent of or notice to the Trustee or any
holder of Indenture Obligations, the Company may, on behalf of itself or any of
its Restricted Subsidiaries, request and instruct the Collateral Agent to, on
behalf of each secured party under the Security Documents, (A) execute and
deliver to the Company, for the benefit of any Person, such release documents as
the Company may reasonably request, of all liens and security interests held by
the Collateral Agent in such assets, and such Person shall be entitled to rely
conclusively on such release document, and (B) deliver any such assets in the
possession of the Collateral Agent to the Company. From and after the date when
all liens granted in favor of the holders of Existing Credit Facility
Obligations are released, the provisions regarding security described above will
no longer apply.

     (16)  Subsidiary Guarantees. Each Subsidiary Guarantor irrevocably and
unconditionally guarantees, jointly and severally, on a senior basis, the full
and punctual payment (whether at Stated Maturity, upon acceleration, optional
redemption, upon repurchase following a Change of Control Offer or an Asset Sale
Offer or otherwise) of the principal of, premium, if any, and interest and
Liquidated Damages, if any, on, and all other amounts payable under, this Note
provided for under this Indenture, and the full and punctual payment of all
other amounts payable by the Company under the Indenture; provided that,
notwithstanding anything to the contrary herein, the aggregate amount of the
Obligations guaranteed under the Indenture by any Subsidiary Guarantor shall be
limited in amount to the maximum amount that would not render such Subsidiary
Guarantor's obligations subject to avoidance under the applicable fraudulent
conveyance provisions of the United States Bankruptcy Code or any comparable
provision of any applicable state law.

     (17)  Additional Subsidiary Guarantees. If any of the Company's Restricted
Subsidiaries shall Guarantee or secure the payment of any other Indebtedness of
the Company or any of its Restricted Subsidiaries, then, subject to certain
exceptions

                                      A-9
<PAGE>

specified in the Indenture, such Restricted Subsidiary shall become a Subsidiary
Guarantor by executing a supplemental indenture.

     (18)  Trustee Dealings with Company. The Trustee under the Indenture, in
its individual or any other capacity, may become the owner or pledgee of Notes
and may make loans to, accept deposits from, perform services for, and otherwise
deal with, the Company and its Affiliates as if it were not the Trustee.

     (19)  Authentication. This Note shall not be valid until the Trustee signs
the certificate of authentication on this Note.

     (20)  Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=

     (21)  Governing Law. This Note shall be governed by and construed in
accordance with the internal laws of the State of New York, without giving
effect to any principles of conflict of laws to the extent that the application
of the law of another jurisdiction is required thereby.

     The Company will furnish to any Holder upon written request and without
charge a copy of the Indenture. Requests may be made to the Company, One Houston
