Dear Sirs:

     United States Steel LLC, a Delaware limited liability company, and United
States Steel Financing Corp., a Delaware corporation (collectively, the
"Issuers"), propose to issue and sell to Credit Suisse First Boston Corporation,
J.P. Morgan Securities Inc., Lehman Brothers Inc., Salomon Smith Barney, BNY
Capital Markets, Inc., Mellon Financial Markets, LLC, NatCity Investments, Inc.,
PNC Capital Markets, Inc. and Scotia Capital (USA) Inc. (collectively, the
"Initial Purchasers"), upon the terms set forth in a purchase agreement dated
September 6, 2001 (the "Purchase Agreement"), $150,000,000 aggregate principal
amount of their 10  3/4 % Senior Notes due August 1, 2008 (the "Initial
Securities") to be fully and unconditionally guaranteed (the "Guarantee") by USX
Corporation (the "Guarantor") until such time, subject to certain exceptions, as
the Guarantor shall have effected a reorganization (the "Separation Date"), such
that United States Steel LLC is merged into United States Steel Corporation and
is no longer a subsidiary of the Guarantor (the "Separation").  References
herein to the "Company" apply collectively to the Issuers and the Guarantor
until the Separation, after which time such reference will apply to United
States Steel Corporation, as successor to the Issuers.  The Initial Securities
will be issued pursuant to an Indenture, dated as of July 27, 2001 (the
"Indenture"), among the Issuers, the Guarantor and The Bank of New York, as
trustee  (the "Trustee").  As an inducement to the Initial Purchasers to enter
into the Purchase Agreement, the Company agrees with the Initial Purchasers, for
the benefit of the Initial Purchasers and the holders of the Securities (as
defined below) (collectively the "Holders"), as follows:

     1. Registered Exchange Offer. Unless not permitted by applicable law (after
the Company has complied with the final paragraph of this Section 1), the
Company shall prepare and, on or before March 31, 2002, file (the date of such
filing being the "Filing Date") with the Securities and Exchange Commission (the
"Commission") a registration statement (the "Exchange Offer Registration
Statement") on an appropriate form under the Securities Act of 1933, as amended
(the "Securities Act"), with respect to a proposed offer (the "Registered
Exchange Offer") to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the Commission
from participating in the Registered Exchange Offer, to issue and deliver to
such Holders, in exchange for the Initial Securities, a like aggregate principal
amount of debt securities of the Company issued under the
<PAGE>

Indenture, identical in all material respects to the Initial Securities
(excluding terms with respect to transfer restrictions, which shall be omitted)
and registered under the Securities Act (the "Exchange Securities"). The Company
shall use its commercially reasonable efforts to (i) cause such Exchange Offer
Registration Statement to be declared effective under the Securities Act within
90 days after the Filing Date and (ii) keep the Exchange Offer Registration
Statement effective for not less than 30 days (or longer, if required by
applicable law) after the date notice of the Registered Exchange Offer is mailed
to the Holders (such period being called the "Exchange Offer Registration
Period").

     If the Company commences the Registered Exchange Offer, the Company (i)
will be entitled to consummate the Registered Exchange Offer 30 days after such
commencement (provided that the Company has accepted all the Initial Securities
theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer) and (ii) will be required to consummate the Registered Exchange
Offer no later than 40 days after the date on which the Exchange Offer
Registration Statement is declared effective.

     Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall as soon as practicable commence the
Registered Exchange Offer, it being the objective of such Registered Exchange
Offer to enable each Holder of Transfer Restricted Securities electing to
exchange the Initial Securities for Exchange Securities (assuming that such
Holder is not an affiliate of the Company within the meaning of the Securities
Act, acquires the Exchange Securities in the ordinary course of such Holder's
business and has no arrangements with any person to participate in the
distribution of the Exchange Securities and is not prohibited by any law or
policy of the Commission from participating in the Registered Exchange Offer) to
trade such Exchange Securities from and after their receipt without any
limitations or restrictions under the Securities Act and without material
restrictions under the securities laws of the several states of the United
States.

     The Company acknowledges that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (i) each Holder that is a broker-dealer electing
to exchange Initial Securities acquired for its own account as a result of
market making activities or other trading activities for Exchange Securities (an
"Exchanging Dealer"), is required to deliver a prospectus containing the
information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in
the "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer"
section, and (c) Annex C hereto in the "Plan of Distribution" section of such
prospectus in connection with a sale of any such Exchange Securities received by
such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an
Initial Purchaser that elects to sell Securities (as defined below) acquired in
exchange for Initial Securities constituting any portion of an unsold allotment
is required to deliver a prospectus containing the information required by Items
507 or 508 of Regulation S-K under the Securities Act, as applicable, in
connection with such sale.

     The Company shall use commercially reasonable efforts to keep the Exchange
Offer Registration Statement effective and to amend and supplement the
prospectus contained therein, in order to permit such prospectus to be lawfully
delivered by all persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such persons must comply with such
requirements in order to resell the Exchange Securities; provided, however, that
                                                         --------  -------
(i) in the case where such prospectus and any amendment or supplement thereto
must be delivered by an Exchanging Dealer or an Initial Purchaser, such period
shall be the lesser of 180 days and the date on which all Exchanging Dealers and
the Initial Purchasers have sold all Exchange Securities held by them (unless
such period is extended pursuant to Section 3(j) below) and (ii) the Company
shall make such prospectus and any amendment or supplement thereto available to
any broker-dealer for use in connection with any resale of any Exchange
Securities for a period of not less than 180 days after the consummation of the
Registered Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and identical in all material respects to the Initial
Securities (the "Private


                                       2
<PAGE>

Exchange Securities"). The Initial Securities, the Exchange Securities and the
Private Exchange Securities are herein collectively called the "Securities".

     In connection with the Registered Exchange Offer, the Company shall:

          (a) mail to each Holder a copy of the prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;

          (b) keep the Registered Exchange Offer open for not less than 30 days
     (or longer, if required by applicable law) after the date notice thereof is
     mailed to the Holders;

          (c) permit Holders to withdraw tendered Securities at any time prior
     to the close of business, New York time, on the last business day on which
     the Registered Exchange Offer shall remain open; and

          (d) otherwise comply with applicable provisions of the Securities Act,
     the Exchange Act and the Trust Indenture Act.

     As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Company shall:

          (x) accept for exchange all the Securities validly tendered and not
     withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

          (y) deliver to the Trustee for cancellation all the Initial Securities
     so accepted for exchange; and

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

     The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the
Securities will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the date of original issue of the Initial
Securities.

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder
will be acquired in the ordinary course of business, (ii) such Holder will have
no arrangements or understanding with any person to participate in the
distribution of the Securities or the Exchange Securities within the meaning of
the Securities Act, (iii) such Holder is not an "affiliate," as defined in Rule
405 of the Securities Act, of the Company or if it is an affiliate, such Holder
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable, (iv) if such Holder is not a broker-
dealer, that it is not engaged in, and does not intend to engage in, the
distribution of the Exchange Securities and (v) if such Holder is a broker-
dealer, that it will receive Exchange Securities for its own account in exchange
for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Securities.

     Notwithstanding any other provisions hereof, the Company will ensure that
(i) any Exchange Offer Registration Statement and any amendment thereto and any
prospectus forming part thereof and any


                                       3
<PAGE>

supplement thereto complies in all material respects with the Securities Act and
the rules and regulations thereunder, (ii) any Exchange Offer Registration
Statement and any amendment thereto does not, when it becomes effective, contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
and (iii) any prospectus forming part of any Exchange Offer Registration
Statement, and any supplement to such prospectus, does not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

     If following the date hereof there has been announced a change in
Commission policy with respect to exchange offers that in the reasonable opinion
of counsel to the Company raises a substantial question as to whether the
Registered Exchange Offer is permitted by applicable federal law, the Company
will seek a no-action letter or other favorable decision from the Commission
allowing the Company to consummate the Registered Exchange Offer.  The Company
will pursue the issuance of such a decision to the Commission staff level.  In
connection with the foregoing, the Company will take all such other commercially
reasonable actions as may be requested by the Commission or otherwise required
in connection with the issuance of such decision, including without limitation
(i) participating in telephonic conferences with the Commission, (ii) 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 the
Registered Exchange Offer should be permitted and (iii) diligently pursuing a
resolution (which need not be favorable) by the Commission staff.

     2. Shelf Registration. If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the Company
is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Exchange Offer Registration Statement is not filed
with the Commission by the Filing Deadline or the Registered Exchange Offer is
not consummated by the 130th day after the Filing Date, (iii) any Initial
Purchaser so requests with respect to the Initial Securities (or the Private
Exchange Securities) not eligible to be exchanged for Exchange Securities in the
Registered Exchange Offer and held by it following consummation of the
Registered Exchange Offer or (iv) any Holder (other than an Exchanging Dealer)
is not eligible to participate in the Registered Exchange Offer or, in the case
of any Holder (other than an Exchanging Dealer) that participates in the
Registered Exchange Offer, such Holder does not receive freely tradeable
Exchange Securities on the date of the exchange and any such Holder so requests,
the Company shall take the following actions (the date on which any of the
conditions described in the foregoing clauses (ii) through (iv) occur, including
in the case of clauses (iii) or (iv) the receipt of the required notice, being a
"Trigger Date"):

          (a) The Company shall promptly (but in no event later than March 31,
     2002 in the case of clause (i) above, or 90 days after the Trigger Date in
     the case of clause (ii), (iii) or (iv) above) file with the Commission a
     registration statement (the "Shelf Registration Statement" and, together
     with the Exchange Offer Registration Statement, a "Registration Statement")
     on an appropriate form under the Securities Act relating to the offer and
     sale of the Transfer Restricted Securities by the Holders thereof from time
     to time in accordance with the methods of distribution set forth in the
     Shelf Registration Statement and Rule 415 under the Securities Act
     (hereinafter, the "Shelf Registration") and thereafter (x) in the case of
     clause (i) above, the Company will use commercially reasonable efforts to
     cause the Shelf Registration Statement to be declared effective under the
     Securities Act on or prior to the 90th calendar day following the Filing
     Date; or (y) in the case of clause (ii), (iii), or (iv) above, the Company
     will use commercially reasonable efforts to cause the Shelf Registration
     Statement to be declared effective under the Securities Act prior to the
     90th day after the date (the "Shelf Filing Date") such Shelf Registration
     Statement is filed with the Commission; provided, however, that no Holder
                                             --------  -------
     (other than an Initial Purchaser) shall be entitled to have the Securities
     held by it covered by such Shelf Registration Statement unless such Holder
     agrees in writing to be bound by all the provisions of this Agreement
     applicable to such Holder.

          (b) The Company shall use its commercially reasonable efforts to keep
     the Shelf Registration Statement continuously effective in order to permit
     the prospectus included therein to be lawfully delivered by the Holders of
     the relevant Securities, for a period of two years (or for such longer
     period if extended pursuant to Section 3(j) below) from the date of its
     effectiveness or


                                       4
<PAGE>

     such shorter period that will terminate when all the Securities covered by
     the Shelf Registration Statement (i) have been sold pursuant thereto or
     (ii) are no longer restricted securities (as defined in Rule 144 under the
     Securities Act, or any successor rule thereof).

          (c) Notwithstanding any other provisions of this Agreement to the
     contrary, the Company shall cause the Shelf Registration Statement and the
     related prospectus and any amendment or supplement thereto, as of the
     effective date of the Shelf Registration Statement, amendment or
     supplement, (i) to comply in all material respects with the applicable
     requirements of the Securities Act and the rules and regulations of the
     Commission and (ii) not to contain any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     in order to make the statements therein, in light of the circumstances
     under which they were made, not misleading.

     3. Registration Procedures. In connection with any Shelf Registration
contemplated by Section 2 hereof and, to the extent applicable, any Registered
Exchange Offer contemplated by Section 1 hereof, the following provisions shall
apply:

          (a) The Company shall (i) furnish to each Initial Purchaser, prior to
     the filing thereof with the Commission, a copy of the Registration
     Statement and each amendment thereof and each supplement, if any, to the
     prospectus included therein and, in the event that an Initial Purchaser
     (with respect to any portion of an unsold allotment from the original
     offering) is participating in the Registered Exchange Offer or the Shelf
     Registration Statement, the Company shall use its commercially reasonable
     efforts to reflect in each such document, when so filed with the
     Commission, such comments as such Initial Purchaser reasonably may propose;
     (ii) include the information set forth in Annex A hereto on the cover, in
     Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose
     of the Exchange Offer" section and in Annex C hereto in the "Plan of
     Distribution" section of the prospectus forming a part of the Exchange
     Offer Registration Statement and include the information set forth in Annex
     D hereto in the Letter of Transmittal delivered pursuant to the Registered
     Exchange Offer; (iii) if requested by an Initial Purchaser, include the
     information required by Items 507 or 508 of Regulation S-K under the
     Securities Act, as applicable, in the prospectus forming a part of the
     Exchange Offer Registration Statement; (iv) include within the prospectus
     contained in the Exchange Offer Registration Statement a section entitled
     "Plan of Distribution," reasonably acceptable to the Initial Purchasers,
     which shall contain a summary statement of the positions taken or policies
     made by the staff of the Commission with respect to the potential
     "underwriter" status of any broker-dealer that is the beneficial owner (as
     defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended
     (the "Exchange Act")) of Exchange Securities received by such broker-dealer
     in the Registered Exchange Offer (a "Participating Broker-Dealer"), whether
     such positions or policies have been publicly disseminated by the staff of
     the Commission or such positions or policies, in the reasonable judgment of
     the Initial Purchasers based upon advice of counsel (which may be in-house
     counsel), represent the prevailing views of the staff of the Commission;
     and (v) in the case of a Shelf Registration Statement, include the names of
     the Holders who propose to sell Securities pursuant to the Shelf
     Registration Statement as selling securityholders; provided that such
     Holders have provided the Company with such information prior to the filing
     of the Shelf Registration Statement.

          (b) The Company shall give written notice to the Initial Purchasers,
     the Holders of the Securities and any Participating Broker-Dealer from whom
     the Company has received prior written notice that it will be a
     Participating Broker-Dealer in the Registered Exchange Offer (which notice
     pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction
     to suspend the use of the prospectus until the requisite changes have been
     made):

               (i) when the Registration Statement or any amendment thereto has
          been filed with the Commission and when the Registration Statement or
          any post- effective amendment thereto has become effective;


                                       5
<PAGE>

               (ii) of any request by the Commission for amendments or
          supplements to the Registration Statement or the prospectus included
          therein or for additional information;

               (iii) of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

               (iv) of the receipt by the Company or its legal counsel of any
          notification with respect to the suspension of the qualification of
          the Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose; and

               (v) of the happening of any event that requires the Company to
          make changes in the Registration Statement or the prospectus in order
          that the Registration Statement or the prospectus do not contain an
          untrue statement of a material fact nor omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein (in the case of the prospectus, in light of the circumstances
          under which they were made) not misleading.

          (c) The Company shall use commercially reasonable efforts to obtain
     the withdrawal at the earliest possible time, of any order suspending the
     effectiveness of the Registration Statement.

          (d) The Company shall furnish to each Holder of Securities included
     within the coverage of the Shelf Registration, without charge, at least one
     copy of the Shelf Registration Statement and any post-effective amendment
     thereto, including financial statements and schedules, and, if the Holder
     so requests in writing, all exhibits thereto (including those, if any,
     incorporated by reference).

          (e) The Company shall deliver to each Exchanging Dealer and each
     Initial Purchaser, and to any other Holder who so requests, in each case
     upon requests, without charge, at least one copy of the Exchange Offer
     Registration Statement and any post-effective amendment thereto, including
     financial statements and schedules, and, if any Initial Purchaser or any
     such Holder requests, all exhibits thereto (including those incorporated by
     reference).

          (f) The Company shall, during the Shelf Registration Period, deliver
     to each Holder of Securities included within the coverage of the Shelf
     Registration, without charge, as many copies of the prospectus (including
     each preliminary prospectus) included in the Shelf Registration Statement
     and any amendment or supplement thereto as such person may reasonably
     request. The Company consents, subject to the provisions of this Agreement,
     to the use of the prospectus or any amendment or supplement thereto by each
     of the selling Holders of the Securities in connection with the offering
     and sale of the Securities covered by the prospectus, or any amendment or
     supplement thereto, included in the Shelf Registration Statement.

          (g) The Company shall deliver to each Initial Purchaser, any
     Exchanging Dealer, any Participating Broker-Dealer and such other persons
     required to deliver a prospectus following the Registered Exchange Offer,
     without charge, as many copies of the final prospectus included in the
     Exchange Offer Registration Statement and any amendment or supplement
     thereto as such persons may reasonably request. The Company consents,
     subject to the provisions of this Agreement, to the use of the prospectus
     or any amendment or supplement thereto by any Initial Purchaser, if
     necessary, any Participating Broker-Dealer and such other persons required
     to deliver a prospectus following the Registered Exchange Offer in
     connection with the offering and sale of the Exchange Securities covered by
     the prospectus, or any amendment or supplement thereto, included in such
     Exchange Offer Registration Statement.

          (h) Prior to any public offering of the Securities pursuant to any
     Registration Statement the Company shall register or qualify or cooperate
     with the Holders of the Securities included therein and their respective
     counsel in connection with the registration or qualification of the


                                       6
<PAGE>

     Securities for offer and sale under the securities or "blue sky" laws of
     such states of the United States as any Holder of the Securities reasonably
     requests in writing and do any and all other acts or things necessary or
     advisable to enable the offer and sale in such jurisdictions of the
     Securities covered by such Registration Statement; provided, however, that
                                                        --------  -------
     the Company shall not be required to (i) qualify generally to do business
     in any jurisdiction where it is not then so qualified or (ii) take any
     action which would subject it to general service of process or to taxation
     in any jurisdiction where it is not then so subject.

          (i) The Company shall cooperate with the Holders of the Securities to
     facilitate the timely preparation and delivery of certificates representing
     the Securities to be sold pursuant to any Registration Statement free of
     any restrictive legends and in such denominations and registered in such
     names as the Holders may request a reasonable period of time prior to sales
     of the Securities pursuant to such Registration Statement.

          (j) Upon the occurrence of any event contemplated by paragraphs (ii)
     through (v) of Section 3(b) above during the period for which the Company
     is required to maintain an effective Registration Statement, the Company
     shall promptly prepare and file a post-effective amendment to the
     Registration Statement or a supplement to the related prospectus and any
     other required document so that, as thereafter delivered to Holders of the
     Securities or purchasers of Securities, the prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading.
     If the Company notifies the Initial Purchasers, the Holders of the
     Securities and any known Participating Broker-Dealer in accordance with
     paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the
     prospectus until the requisite changes to the prospectus have been made,
     then the Initial Purchasers, the Holders of the Securities and any such
     Participating Broker-Dealers shall suspend use of such prospectus, and the
     period of effectiveness of the Shelf Registration Statement provided for in
     Section 2(b) above and the Exchange Offer Registration Statement provided
     for in Section 1 above shall each be extended by the number of days from
     and including the date of the giving of such notice to and including the
     date when the Initial Purchasers, the Holders of the Securities and any
     known Participating Broker-Dealer shall have received such amended or
     supplemented prospectus pursuant to this Section 3(j).

          (k) Not later than the effective date of the applicable Registration
     Statement, the Company will provide a CUSIP number for the Initial
     Securities, the Exchange Securities or the Private Exchange Securities, as
     the case may be, and provide the applicable trustee with printed
     certificates for the Initial Securities, the Exchange Securities or the
     Private Exchange Securities, as the case may be, in a form eligible for
     deposit with The Depository Trust Company.

          (l) The Company will comply with all rules and regulations of the
     Commission to the extent and so long as they are applicable to the
     Registered Exchange Offer or the Shelf Registration and will make generally
     available to its security holders (or otherwise provide in accordance with
     Section 11(a) of the Securities Act) an earnings statement satisfying the
     provisions of Section 11(a) of the Securities Act, no later than 45 days
     after the end of a 12-month period (or 90 days, if such period is a fiscal
     year) beginning with the first month of the Company's first fiscal quarter
     commencing after the effective date of the Registration Statement, which
     statement shall cover such 12-month period.

          (m) The Company shall cause the Indenture to be qualified under the
     Trust Indenture Act of 1939, as amended, (the "Trust Indenture Act") in a
     timely manner and containing such changes, if any, as shall be necessary
     for such qualification. In the event that such qualification would require
     the appointment of a new trustee under the Indenture, the Company shall
     appoint a new trustee thereunder pursuant to the applicable provisions of
     the Indenture.

          (n) The Company may require each Holder of Securities to be sold
     pursuant to the Shelf Registration Statement to furnish to the Company such
     information regarding the Holder and the distribution of the Securities as
     the Company may from time to time reasonably require for


                                       7
<PAGE>

     inclusion in the Shelf Registration Statement, and the Company may exclude
     from such registration the Securities of any Holder that unreasonably fails
     to furnish such information within a reasonable time after receiving such
     request.

          (o) The Company shall enter into such customary agreements (including,
     if requested, an underwriting agreement in customary form) and take all
     such other action, if any, as any Holder of the Securities shall reasonably
     request in order to facilitate the disposition of the Securities pursuant
     to any Shelf Registration.

          (p) In the case of any Shelf Registration, subject to customary
     confidentiality arrangements, the Company shall (i) make reasonably
     available for inspection by the Holders of the Securities, any underwriter
     participating in any disposition pursuant to the Shelf Registration
     Statement and any attorney, accountant or other agent retained by the
     Holders of the Securities or any such underwriter all relevant financial
     and other records, pertinent corporate documents and properties of the
     Company and (ii) cause the Company's officers, directors, employees,
     accountants and auditors to supply all relevant information reasonably
     requested by the Holders of the Securities or any such underwriter,
     attorney, accountant or agent in connection with the Shelf Registration
     Statement, in each case, as shall be reasonably necessary to enable such
     persons, to conduct a reasonable investigation within the meaning of
     Section 11 of the Securities Act; provided, however, that the foregoing
                                       -------- --------
     inspection and information gathering shall be coordinated on behalf of the
     Initial Purchasers by you and on behalf of the other parties, by one
     counsel designated by and on behalf of such other parties as described in
     Section 4 hereof.

          (q) In the case of any Shelf Registration, the Company, if requested
     by any Holder of Securities covered thereby, shall cause (i) its counsel
     (which counsel may be an employee of the Guarantor or an Issuer) to deliver
     an opinion and updates thereof relating to the Securities in customary form
     addressed to such Holders and the managing underwriters, if any, thereof
     and dated, in the case of the initial opinion, the effective date of such
     Shelf Registration Statement (it being agreed that the matters to be
     covered by such opinion shall include, without limitation, the due
     incorporation and good standing of the Company and its subsidiaries; the
     qualification of the Company and its subsidiaries to transact business as
     foreign corporations; the due authorization, execution and delivery of the
     relevant agreement of the type referred to in Section 3(o) hereof; the due
     authorization, execution, authentication and issuance, and the validity and
     enforceability, of the applicable Securities; the absence of material legal
     or governmental proceedings involving the Company and its subsidiaries; the
     absence of governmental approvals required to be obtained in connection
     with the Shelf Registration Statement, the offering and sale of the
     applicable Securities, or any agreement of the type referred to in Section
     3(o) hereof; the compliance as to form of such Shelf Registration Statement
     and any documents incorporated by reference therein and of the Indenture
     with the requirements of the Securities Act and the Trust Indenture Act,
     respectively; and, as of the date of the opinion and as of the effective
     date of the Shelf Registration Statement or most recent post-effective
     amendment thereto, as the case may be, the absence from such Shelf
     Registration Statement and the prospectus included therein, as then amended
     or supplemented, and from any documents incorporated by reference therein
     of an untrue statement of a material fact or the omission to state therein
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading (in the case of any such documents, in
     the light of the circumstances existing at the time that such documents
     were filed with the Commission under the Exchange Act); (ii) its officers
     to execute and deliver all customary documents and certificates and updates
     thereof requested by any underwriters of the applicable Securities and
     (iii) its independent public accountants and the independent public
     accountants with respect to any other entity for which financial
     information is provided in the Shelf Registration Statement to provide to
     the selling Holders of the applicable Securities and any underwriter
     therefor a comfort letter in customary form and covering matters of the
     type customarily covered in comfort letters in connection with primary
     underwritten offerings, subject to receipt of appropriate documentation as
     contemplated, and only if permitted, by Statement of Auditing Standards No.
     72.

          (r) In the case of the Registered Exchange Offer, if requested by any
     Initial Purchaser or any known Participating Broker-Dealer, the Company
     shall cause (i) its counsel to deliver to such


                                       8
<PAGE>

     Initial Purchaser or such Participating Broker-Dealer a signed opinion in
     the form set forth in Section 7(c) - (e) of the Purchase Agreement with
     such changes as are customary in connection with the preparation of a
     Registration Statement and (ii) its independent public accountants and the
     independent public accountants with respect to any other entity for which
     financial information is provided in the Registration Statement to deliver
     to such Initial Purchaser or such Participating Broker-Dealer a comfort
     letter, in customary form, meeting the requirements as to the substance
     thereof as set forth in Section 7(a) and (b) of the Purchase Agreement,
     with appropriate date changes.

          (s) If a Registered Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Initial Securities by Holders to the
     Company (or to such other Person as directed by the Company) in exchange
     for the Exchange Securities or the Private Exchange Securities, as the case
     may be, the Company shall mark, or caused to be marked, on the Initial
     Securities so exchanged that such Initial Securities are being canceled in
     exchange for the Exchange Securities or the Private Exchange Securities, as
     the case may be; in no event shall the Initial Securities be marked as paid
     or otherwise satisfied.

          (t) The Company will use its commercially reasonable efforts to (a) if
     the Initial Securities have been rated prior to the initial sale of such
     Initial Securities, confirm such ratings will apply to the Securities
     covered by a Registration Statement, or (b) if the Initial Securities were
     not previously rated, cause the Securities covered by a Registration
     Statement to be rated with the appropriate rating agencies, if so requested
     by Holders of a majority in aggregate principal amount of Securities
     covered by such Registration Statement, or by the managing underwriters, if
     any.

          (u) In the event that any broker-dealer registered under the Exchange
     Act shall underwrite any Securities or participate as a member of an
     underwriting syndicate or selling group or "assist in the distribution"
     (within the meaning of the Conduct Rules (the "Rules") of the National
     Association of Securities Dealers, Inc. ("NASD")) thereof, whether as a
     Holder of such Securities or as an underwriter, a placement or sales agent
     or a broker or dealer in respect thereof, or otherwise, the Company will
     assist such broker-dealer in complying with the requirements of such Rules,
     including, without limitation, by (i) if such Rules, including Rule 2720,
     shall so require, engaging a "qualified independent underwriter" (as
     defined in Rule 2720) to participate in the preparation of the Registration
     Statement relating to such Securities, to exercise usual standards of due
     diligence in respect thereto and, if any portion of the offering
     contemplated by such Registration Statement is an underwritten offering or
     is made through a placement or sales agent, to recommend the yield of such
     Securities, (ii) indemnifying any such qualified independent underwriter to
     the extent of the indemnification of underwriters provided in Section 5
     hereof and (iii) providing such information to such broker-dealer as may be
     required in order for such broker-dealer to comply with the requirements of
     the Rules.

          (v) The Company shall use its commercially reasonable efforts to take
     all other steps necessary to effect the registration of the Securities
     covered by a Registration Statement contemplated hereby.

     4. Registration Expenses. (a) All expenses incident to the Company's
performance of and compliance with this Agreement will be borne by the Company,
regardless of whether a Registration Statement is ever filed or 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 Securities to be issued in the Registered Exchange Offer and
          the Private Exchange and printing of Prospectuses), messenger and
          delivery services and telephone;


                                       9
<PAGE>

               (iv) all fees and disbursements of counsel for the Company;

               (v) all application and filing fees in connection with listing
          the Exchange Securities on a national 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 (including the expenses of any special
          audit and comfort letters required by or incident to such
          performance).

     (b) In connection with any Registration Statement required by this
Agreement, the Company will reimburse the Initial Purchasers and the Holders of
Transfer Restricted Securities who are tendering Initial Securities in the
Registered Exchange Offer and/or selling or reselling Securities 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 Simpson Thacher &
Bartlett 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.

     5. Indemnification. (a) Each of the Issuers and the Guarantor, jointly and
severally, agrees to indemnify and hold harmless each Holder of the Securities,
any Participating Broker-Dealer and each person, if any, who controls such
Holder or such Participating Broker-Dealer within the meaning of the Securities
Act or the Exchange Act (each Holder, any Participating Broker-Dealer and such
controlling persons are referred to collectively as the "Indemnified Parties")
from and against any losses, claims, damages or liabilities, joint or several,
or any actions in respect thereof (including, but not limited to, any losses,
claims, damages, liabilities or actions relating to purchases and sales of the
Securities) to which each Indemnified Party may become subject under the
Securities Act, the Exchange Act or otherwise, insofar as such losses, claims,
damages, liabilities or actions arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of, or are based upon, the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and shall reimburse, as incurred, the Indemnified
Parties for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action in respect thereof; provided, however, that (i) the Issuers
                                        --------  -------
or the Guarantor shall not be liable in any such case to the extent that such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration in reliance
upon and in conformity with written information pertaining to such Holder and
furnished to the Issuers or Guarantor by or on behalf of such Holder
specifically for inclusion therein and (ii) with respect to any untrue statement
or omission or alleged untrue statement or omission made in any preliminary
prospectus relating to a Shelf Registration Statement, the indemnity agreement
contained in this subsection (a) shall not inure to the benefit of any Holder or
Participating Broker-Dealer from whom the person asserting any such losses,
claims, damages or liabilities purchased the Securities concerned, to the extent
that a prospectus relating to such Securities was required to be delivered by
such Holder or Participating Broker-Dealer under the Securities Act in
connection with such purchase and any such loss, claim, damage or liability of
such Holder or Participating Broker-Dealer results from the fact that there was
not sent or given to such person, at or prior to the written confirmation of the
sale of such Securities to such person, a copy of the final prospectus if the
Issuers or Guarantor had previously furnished copies thereof to such Holder or
Participating Broker-Dealer; provided further, however, that this indemnity
                             -------- -------  -------
agreement will be in addition to any liability which the Issuers or Guarantor
may otherwise have to such Indemnified Party.  Each of the Issuers and the
Guarantor shall also jointly and severally indemnify underwriters, their
officers and directors and each person who controls such underwriters within the
meaning of the Securities Act or the Exchange Act to the same extent as provided
above with respect to the indemnification of the Holders of the Securities if
requested by such Holders.


                                       10
<PAGE>

     (b) Each Holder of the Securities and each Participating Broker-Dealer,,
severally and not jointly, will indemnify and hold harmless the Issuers, their
respective officers and directors who sign a Registration Statement and the
Guarantor and each person, if any, who controls the Issuers or Guarantor within
the meaning of the Securities Act or the Exchange Act from and against any
losses, claims, damages or liabilities or any actions in respect thereof, to
which the Issuers or Guarantor or any such controlling person may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the statements therein not misleading, but in
each case only to the extent that the untrue statement or omission or alleged
untrue statement or omission was made in reliance upon and in conformity with
written information pertaining to such Holder or such Participating Broker-
Dealer and furnished to the Issuers or Guarantor by or on behalf of such Holder
specifically for inclusion therein; and, subject to the limitation set forth
immediately preceding this clause, shall reimburse, as incurred, the Issuers or
Guarantor for any legal or other expenses reasonably incurred by the Issuers or
Guarantor or any such controlling person in connection with investigating or
defending any loss, claim, damage, liability or action in respect thereof. This
indemnity agreement will be in addition to any liability which such Holder may
otherwise have to the Issuers or any of their controlling persons.

     (c) Promptly after receipt by an indemnified party under this Section 5 of
notice of the commencement of any action or proceeding (including a governmental
investigation), such indemnified party will, if a claim in respect thereof is to
be made against the indemnifying party under this Section 5, notify the
indemnifying party of the commencement thereof; but the omission so to notify
the indemnifying party will not, in any event, relieve the indemnifying party
from any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above. In case any such action is
brought against any indemnified party, and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other indemnifying
party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall, absent a conflict of
interest, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof the indemnifying party will not be liable to such indemnified
party under this Section 5 for any legal or other expenses, other than
reasonable and documented out-of-pocket costs of investigation, subsequently
incurred by such indemnified party in connection with the defense thereof. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened action in respect of
which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party unless such settlement
includes an unconditional release of such indemnified party from all liability
on any claims that are the subject matter of such action, and does not include a
statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party.

     (d) If the indemnification provided for in this Section 5 is unavailable or
insufficient to hold harmless an indemnified party under subsections (a) or (b)
above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to in subsection (a) or (b)
above (i) in such proportion as is appropriate to reflect the relative benefits
received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the exchange of the Securities, pursuant to
the Registered Exchange Offer, or (ii) if the allocation provided by the
foregoing clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the indemnifying party or parties on
the one hand and the indemnified party on the other in connection with the
statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof) as well as any other relevant
equitable considerations. The relative fault of the parties shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Issuers or the Guarantor on
the one hand or such Holder or such other indemnified party, as the case may be,
on the other, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The


                                       11
<PAGE>

amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities referred to in the first sentence of this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim which is the subject of this subsection (d). Notwithstanding any other
provision of this Section 5(d), the Holders of the Securities shall not be
required to contribute any amount in excess of the amount by which the net
proceeds received by such Holders from the sale of the Securities pursuant to a
Registration Statement exceeds the amount of damages which such Holders have
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this paragraph (d), each person,
if any, who controls such indemnified party within the meaning of the Securities
Act or the Exchange Act shall have the same rights to contribution as such
indemnified party and each person, if any, who controls the Issuers or the
Guarantor within the meaning of the Securities Act or the Exchange Act shall
have the same rights to contribution as the Issuers and the Guarantor.

     (e) The agreements contained in this Section 5 shall survive the sale of
the Securities pursuant to a Registration Statement and shall remain in full
force and effect, regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of any indemnified party.

     6. Additional Interest Under Certain Circumstances. (a) Additional interest
(the "Additional Interest") with respect to the Securities shall be assessed as
follows if any of the following events occur (each such event in clauses (i)
through (vi) below being herein called a "Registration Default"):

           (i)    if the Company fails to file an Exchange Offer Registration
                  Statement or, if obligated to file a Shelf Registration
                  Statement pursuant to Section 2(a)(x), a Shelf Registration
                  Statement with the Commission on or prior to March 31, 2002,

           (ii)   if the Exchange Offer Registration Statement or, if obligated
                  to file a Shelf Registration Statement pursuant to Section
                  2(a)(x), a Shelf Registration Statement is not declared
                  effective by the Commission on or prior to the 90th day after
                  the Filing Date,

           (iii)  if the Exchange Offer is not consummated on or before the 40th
                  day after the Exchange Offer Registration Statement is
                  declared effective,

           (iv)   if obligated to file the Shelf Registration Statement pursuant
                  to Section 2(a)(y) above, the Company fails to file the Shelf
                  Registration Statement with the Commission on or prior to the
                  90th day after the Trigger Date,

           (v)    if obligated to file a Shelf Registration Statement pursuant
                  to Section 2(a)(y) above, the Shelf Registration Statement is
                  not declared effective by the Commission on or prior to the
                  90th day after the Shelf Filing Date, or

           (vi)   any Registration Statement required by this Agreement has been
                  declared effective by the Commission but (A) such Registration
                  Statement thereafter ceases to be effective or (B) such
                  Registration Statement or the related prospectus ceases to be
                  usable in connection with resales of Transfer Restricted
                  Securities during the periods specified herein because either
                  (1) any event occurs as a result of which the related
                  prospectus forming part of such Registration Statement would
                  include any 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, or (2) it shall be necessary to
                  amend such Registration Statement or supplement the related
                  prospectus, to comply with the Securities Act or the Exchange
                  Act or the respective rules thereunder.


                                       12
<PAGE>

Each of the foregoing will constitute a Registration Default whatever the reason
for any such event and whether it is voluntary or involuntary or is beyond the
control of the Company or pursuant to operation of law or as a result of any
action or inaction by the Commission.

     Additional Interest shall accrue on the Securities over and above the
interest set forth in the title of the Securities from and including the date on
which any such Registration Default shall occur to but excluding the date on
which all such Registration Defaults have been cured, at a rate of 0.25% per
annum (the "Additional Interest Rate") for the first 90-day period immediately
following the occurrence of such Registration Default.  The Additional Interest
Rate shall increase by an additional 0.25% per annum with respect to each
subsequent 90-day period until all Registration Defaults have been cured, up to
a maximum Additional Interest Rate of 1.0% per annum.

     (b) A Registration Default referred to in Section 6(a)(vi) hereof shall be
deemed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post- effective
amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Holders to use the related prospectus or (y) other material events with respect
to the Company that would need to be described in such Shelf Registration
Statement or the related prospectus and (ii) in the case of clause (y), the
Company is proceeding promptly and in good faith to amend or supplement such
Shelf Registration Statement and related prospectus to describe such events;
provided, however, that in any case if such Registration Default occurs for a
--------  -------
continuous period in excess of 30 days, Additional Interest shall be payable in
accordance with the above paragraph from the day such Registration Default
occurs until such Registration Default is cured.

     (c) Any amounts of Additional Interest due pursuant to Section 6(a) will be
payable in cash on the regular interest payment dates with respect to the
Securities. The amount of Additional Interest will be determined by multiplying
the applicable Additional Interest Rate by the principal amount of the
Securities and further multiplied by a fraction, the numerator of which is the
number of days such Additional Interest Rate was applicable during such period
(determined on the basis of a 360-day year comprised of twelve 30-day months),
and the denominator of which is 360.

     (d) "Transfer Restricted Securities" means each Security until (i) the date
on which such Security has been exchanged by a person other than a broker-
dealer for a freely transferable Exchange Security in the Registered Exchange
Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange
Offer of an Initial Security for an Exchange Note, the date on which such
Exchange Note is sold to a purchaser who receives from such broker-dealer on or
prior to the date of such sale a copy of the prospectus contained in the
Exchange Offer Registration Statement, (iii) the date on which such Security has
been effectively registered under the Securities Act and disposed of in
accordance with the Shelf Registration Statement or (iv) the date on which such
Security is distributed to the public pursuant to Rule 144 under the Securities
Act or is saleable pursuant to Rule 144(k) under the Securities Act.

     7. Rules 144 and 144A. The Company shall use its commercially reasonable
efforts to file the reports required to be filed by it under the Securities Act
and the Exchange Act in a timely manner and, if at any time the Company is not
required to file such reports, it will, upon the request of any Holder of
Securities, make publicly available other information so long as necessary to
permit sales of their securities pursuant to Rules 144 and 144A. The Company
covenants that it will take such further action as any Holder of Securities may
reasonably request, all to the extent required from time to time to enable such
Holder to sell Securities without registration under the Securities Act within
the limitation of the exemptions provided by Rules 144 and 144A (including the
requirements of Rule 144A(d)(4)). The Company will provide a copy of this
Agreement to prospective purchasers of Initial Securities identified to the
Company by the Initial Purchasers upon request. Upon the request of any Holder
of Initial Securities, the Company shall deliver to such Holder a written
statement as to whether it has complied with such requirements. Notwithstanding
the foregoing, nothing in this Section 7 shall be deemed to require the Company
to register any of its securities pursuant to the Exchange Act.

     8. Underwritten Registrations. If any of the Transfer Restricted Securities
covered by any Shelf Registration are to be sold in an underwritten offering,
the investment banker or investment bankers and manager or managers that will
administer the offering ("Managing Underwriters") will be selected by the
Holders of a majority in aggregate principal amount of such Transfer Restricted
Securities to be included in such offering.

     No person may participate in any underwritten registration hereunder unless
such person (i) agrees to sell such person's Transfer Restricted Securities on
the basis reasonably provided in any underwriting arrangements approved by the
persons entitled hereunder to approve such arrangements and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements.

     9. Miscellaneous.

     (a) Remedies. The Company acknowledges and agrees that any failure by the
Company to comply with its obligations under Section 1 and 2 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 obligations under Sections 1 and
2 hereof. The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

     (b) No Inconsistent Agreements. The Company will not 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. 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 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 departures from
the provisions hereof may not be given, except by the Company and the written
consent of the Holders of a majority in principal amount of the Securities
affected by such amendment, modification, supplement, waiver or consents.

in every other respect and of the remaining provisions contained herein shall
not be affected or impaired thereby.

     (k) Securities Held by the Company. Whenever the consent or approval of
Holders of a specified percentage of principal amount of Securities is required
hereunder, Securities held by the Company or its affiliates (other than
subsequent Holders of Securities if such subsequent Holders are deemed to be
affiliates solely by reason of their holdings of such Securities) shall not be
counted in determining whether such consent or approval was given by the Holders
of such required percentage.

delivery of this Agreement, each of the parties hereby submits to the non-
exclusive jurisdiction of the Federal and state courts in the Borough of

extent that any of the parties may acquire any immunity from jurisdiction of any
court or from any legal process (whether through service of notice, attachment
prior to judgment, attachment in aid of execution, execution or otherwise) with

     Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  The
Letter of Transmittal states that by so acknowledging and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.  This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Securities received in exchange for
Initial Securities where such Initial Securities were acquired by such broker-
dealer as a result of market-making activities or other trading activities.  The
Company has agreed that, for a period of 180 days after the Expiration Date (as
defined herein), it will make this Prospectus available to any broker-dealer for
use in connection with any such resale.  See "Plan of Distribution."

     Each broker-dealer that receives Exchange Securities for its own account in
exchange for Initial Securities, where such Initial Securities were acquired by
such broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities.  See "Plan of Distribution."

                                                                         ANNEX C



                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities.  This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Initial Securities where such Initial Securities were acquired as a
result of market-making activities or other trading activities.  The Company has
agreed that, for a period of 180 days after the Expiration Date, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for
use in connection with any such resale.  In addition, until _________________ ,
200_ ,  all dealers effecting transactions in the Exchange Securities may be
required to deliver a prospectus.(1)

     The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers.  Exchange Securities received by broker-dealers
for their own account pursuant to the Exchange Offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities.  Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act.  The Letter of Transmittal states that,
by acknowledging that it will deliver and by delivering a prospectus, a broker-
dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     For a period of 180 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.  The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
