          (a) Exchange Offer. To the extent not prohibited by any applicable law
              --------------
     or applicable interpretation of the staff of the SEC, the Company shall,
     for the benefit of the Holders, at the Company's cost, use its reasonable
     best efforts to (i) cause to be filed with the SEC an Exchange Offer
     Registration Statement on an appropriate form under the Securities Act
     covering the Exchange Offer, (ii) cause such Exchange Offer Registration
     Statement to be declared effective under the Securities Act by the SEC not
     later than the date that is 240 days after the Issue Date, and (iii) keep
     such Exchange Offer Registration Statement effective for not less than 30
     calendar days (or longer if required by applicable law) after the date
     notice of the Exchange Offer is mailed to the Holders. Upon the
     effectiveness of the Exchange Offer Registration Statement, the Company
     shall promptly commence the Exchange Offer, it being the objective of such
     Exchange Offer to enable each Holder eligible and electing to exchange
     Registrable Notes for a like principal amount of Exchange Notes (assuming
     that such Holder is not an affiliate of the Company within the meaning of
     Rule 405 under the Securities Act and is not a broker-dealer tendering
     Registrable Notes acquired directly from the Company for its own account,
     acquires the Exchange Notes in the ordinary course of such Holder's
     business and has no arrangements or understandings with any Person to
     participate in the Exchange Offer for the purpose of distributing the
     Exchange Notes, and is not prohibited by any law or policy of the SEC from
     participating in the Exchange Offer) to transfer such Exchange Notes from
     and after their receipt without any limitations or restrictions under the
     Securities Act and under state securities or blue sky laws.

          In connection with the Exchange Offer, the Company shall:

          (i) 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;

          (ii) keep the Exchange Offer open for acceptance for a period of not
     less than 30 days after the date notice thereof is mailed to the Holders
     (or longer if required by applicable law) (such period referred to herein
     as the "Exchange Period");

          (iii) utilize the services of the Trustee or the Depositary for the
     Exchange Offer,

          (iv) permit Holders to withdraw tendered Notes at any time prior to
     the close of business, New York time, on the last Business Day of the
     Exchange Period, by sending to the institution specified in the notice, a
     telegram, telex, facsimile transmission or letter setting forth the name of
     such Holder, the principal amount of Notes delivered for

                                       6

<PAGE>

     exchange and a statement that such Holder is withdrawing his election to
     have such Notes exchanged;

          (v) notify each Holder that any Notes not tendered by such Holder in
     the Exchange Offer will remain outstanding and continue to accrue interest,
     but will not retain any rights under this Agreement (except in the case of
     the Initial Purchasers and Participating Broker-Dealers as provided
     herein); and

          (vi) otherwise comply with applicable laws relating to the Exchange
     Offer.

          As soon as practicable after the close of the Exchange Offer, the
Company shall:

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

          (ii) deliver, or cause to be delivered, to the Trustee for
     cancellation all Notes or portions thereof so accepted for exchange by the
     Company; and

          (iii) issue, and cause the Trustee to promptly authenticate and
     deliver to each Holder, Exchange Notes equal in principal amount to the
     principal amount of the Notes as are surrendered by such Holder for
     exchange.

          The Indenture will provide that the Exchange Notes will not be subject
to the restrictive legend set forth on the Registrable Notes or the transfer
restrictions (other than in respect of minimum denominations) set forth in the
Indenture.

          Interest on each Exchange Note issued pursuant to the Registered
Exchange Offer will accrue from the last date on which interest was paid on the
Note surrendered in exchange therefor or, if no interest has been paid on such
Note, from the Issue Date.

          To the extent not prohibited by any law or applicable interpretation
or other action of the staff of the SEC, the Company shall use its reasonable
best efforts to complete the Exchange Offer as provided above, and shall comply
with the applicable requirements of the Securities Act, the Exchange Act and
other applicable laws in connection with the Exchange Offer. The Exchange Offer
shall not be subject to any conditions, other than that the Exchange Offer shall
not violate applicable law or any applicable interpretation of the staff of the
SEC and as provided in the next sentence. Each Holder participating in the
Exchange Offer will be required to represent to the Company at the time of the
consummation of the Exchange Offer:

          (a) that any Exchange Note received by that Holder will be acquired in
     the ordinary course of business;

          (b) that the Holder will have no arrangement or understanding with any
     person to participate in the distribution of the Notes or the Exchange
     Notes within the meaning of the Securities Act;

                                       7

<PAGE>

          (c) that the Holder is not an "affiliate," as defined in Rule 405 of
     the Securities Act, of the Company or, if it is an affiliate, that Holder
     will comply with the registration and prospectus delivery requirements of
     the Securities Act to the extent applicable;

          (d) if that Holder is not a broker-dealer, that it is not engaged in,
     and does not intend to engage in any distribution of the Exchange Notes;
     and

          (e) if that Holder is a broker-dealer, that it will receive Exchange
     Notes for its own account in exchange for Notes that were acquired as a
     result of market-making activities or other trading activities and that it
     will deliver a prospectus in connection with any resale of those Exchange
     Notes.

          Each Holder hereby acknowledges and agrees that any Participating
Broker-Dealer and any such Holder using the Exchange Offer to participate in a
distribution of the Exchange Notes to be acquired in the Exchange Offer (1)
could not under SEC policy as in effect on the date of this Agreement rely on
the position of the SEC enunciated in Morgan Stanley and Co., Inc. (available
June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988),
as interpreted in the SEC's letter to Shearman & Sterling dated July 2, 1993,
and similar no-action letters, and (2) must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with a
secondary resale transaction and that such a secondary resale transaction should
be covered by an effective registration statement containing the selling
security holder information required by Item 507 or 508, as applicable, of
Regulation S-K if the resales are of Exchange Notes obtained by such Holder in
exchange for Notes acquired by such Holder directly from the Company.

          Upon consummation of the Exchange Offer in accordance with this
Section 2(a), the provisions of this Agreement shall continue to apply, mutatis
                                                                        -------
mutandis, solely with respect to Registrable Notes that are Exchange Notes held
--------
by Participating Broker-Dealers, and the Company shall have no further
obligation to register the Registrable Notes (other than pursuant to Section
2(b)(iv)) pursuant to Section 2(b) of this Agreement.

          (b) Shelf Registration. In the event that (i) the Company is not
              ------------------
permitted to effect the Exchange Offer because of any change in law or in
currently prevailing interpretations of the staff of the SEC, or (ii) any Notes
validly tendered pursuant to the Exchange Offer are not exchanged for
corresponding Exchange Notes upon consummation of the Exchange Offer, or (iii)
any Initial Purchaser so requests with respect to Notes not eligible to be
exchanged for Exchange Notes in the Exchange Offer and held by it following the
consummation of the Exchange Offer, or (iv) any applicable law or
interpretations do not permit and Holder of Notes other than the Initial
Purchaser to participate in the Exchange Offer, or (v) any Holder of Notes that
participates in the Exchange Offer does not receive freely transferable Exchange
Notes in exchange for tendered Notes, or (vi) the Company elects (any of the
events specified in (i) - (vi) being a "Shelf Registration Event" and the date
of occurrence thereof, the "Shelf Registration Event Date"), the Company shall
promptly deliver to the Holders written notice thereof and, at its cost, use its

                                       8

<PAGE>

reasonable best efforts to cause to be filed as promptly as practicable after
such Shelf Registration Event Date, as the case may be, and, in any event,
within 45 days after such Shelf Registration Event Date (which shall be no
earlier than 75 days after the Closing Time), a Shelf Registration Statement
providing for the sale by the Holders of all of the Registrable Notes, and shall
use its reasonable best efforts to have such Shelf Registration Statement
declared effective by the SEC as soon as practicable; provided, however, that if
                                                      --------  -------
the Shelf Registration Event is pursuant to clause (iii), the Company may
register such Registrable Notes together with the Exchange Offer Registration
Statement, filed pursuant to Section 2(a), and the requirements as to timing
applicable thereto. No Holder of Registrable Notes shall be entitled to include
any of its Registrable Notes in any Shelf Registration pursuant to this
Agreement unless and until such Holder agrees in writing to be bound by all of
the provisions of this Agreement applicable to such Holder and furnishes to the
Company in writing, within 15 days after receipt of a request therefor, such
information as the Company may, after conferring with counsel with regard to
information relating to Holders that would be required by the SEC to be included
in such Shelf Registration Statement or Prospectus included therein, reasonably
requests for inclusion in any Shelf Registration Statement or Prospectus
included therein. Each Holder as to which any Shelf Registration is being
effected agrees promptly to furnish to the Company all information with respect
to such Holder necessary to make the information previously furnished to the
Company by such Holder not materially misleading.

          The Company agrees to use its reasonable best efforts to keep the
Shelf Registration Statement continuously effective for the Rule 144(k) Period
(subject to extension pursuant to the last paragraph of Section 3 hereof) or for
such shorter period that will terminate when all of the Registrable Notes
covered by the Shelf Registration Statement have been sold pursuant to the Shelf
Registration Statement or cease to be outstanding (the "Effectiveness Period").
                                                                      ------
The Company shall not permit any securities other than Registrable Notes to be
included in the Shelf Registration. The Company will, in the event a Shelf
Registration Statement is declared effective, provide to each Holder a
reasonable number of copies of the Prospectus that is a part of the Shelf
Registration Statement and notify each such Holder when the Shelf Registration
has become effective. The Company further agrees, if necessary, to supplement or
amend the Shelf Registration Statement, if required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registrations, and the Company agrees to
furnish to the Holders of Registrable Securities copies of any such supplement
or amendment promptly after its being used or filed with the SEC.

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

          (d) Effective Registration Statement. An Exchange Offer Registration
              --------------------------------
Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement
pursuant to Section 2(b) hereof (or a combination of the two) will not be deemed
to have become effective unless it

                                       9

<PAGE>

has been declared effective by the SEC; provided, however, that if, after it has
                                        --------  -------
been declared effective, the offering of Registrable Notes pursuant to a Shelf
Registration Statement is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court, such
Registration Statement will be deemed not to have been effective during the
period of such interference, until the offering of Registrable Notes pursuant to
such Registration Statement may legally resume. The Company will be deemed not
to have used its reasonable best efforts to cause the Exchange Offer
Registration Statement or the Shelf Registration Statement, as the case may be,
to become, or to remain, effective during the requisite period if it voluntarily
takes any action that would result in any such Registration Statement not being
declared effective or in the Holders of Registrable Notes covered thereby not
being able to exchange or offer and sell such Registrable Notes during that
period unless such action is required by applicable law.

          (e) Additional Interest. The annual interest rates on the principal
              -------------------
amount of the Notes shall increase by 0.50% per annum (the "Additional
Interest") if any of the following events occur (each event identified in clause
(i), (ii) or (iii) below, an "Additional Interest Event"):

          (i) if the Exchange Offer is not consummated or the Shelf Registration
     Statement does not become effective within 270 days following the Closing
     Date, Additional Interest shall accrue on the Notes from and after that
     date to, but excluding, the date the Exchange Offer is consummated, the
     date the Shelf Registration Statement becomes effective, or the date on
     which all the Notes otherwise become transferable by Holders (other than
     the Company or its affiliates, as such term is refined in Rule 501 (b) of
     Regulation D under the Securities Act) without further registration under
     the Securities Act; or

          (ii) if a Shelf Registration Statement is required to be filed with
     the SEC and becomes effective and later ceases to be effective at any time
     during the period specified by this Agreement, Additional Interest shall
     accrue on the Notes from and after the date such registration statement
     ceases to be effective to, but excluding, such date when the Shelf
     Registration Statement again becomes effective (or, if earlier, the end of
     such period specified by this Agreement); or

          (iii) if the Company ceases to maintain its status as a reporting
     company under the Exchange Act whether or not SEC rules and regulations
     require the Company to maintain that status (unless the SEC will not accept
     the filing of the applicable reports) Additional Interest shall accrue on
     the Notes.

provided, however, that the Additional Interest rate on the Notes may not exceed
--------  -------
in the aggregate 0.5% per annum; provided, further, however that Additional
Interest shall cease to accrue on the Notes as of the date all Additional
Interest Events are cured and cease to exist. Any amount of Additional Interest
due pursuant to Section 2(e) (i), (ii) or (iii) above will be payable in cash on
the relevant payment dates for the payment of interest pursuant to the
Indenture.

          (f) Specific Enforcement. Without limiting the remedies available to
              --------------------
the Holders, the Company acknowledges that any failure by the Company to comply
with its obligations under Section 2(a) and Section 2(b) hereof may result in
material irreparable injury to the Holders for which there is no adequate remedy
at law, that it would not be possible to measure damages for such injuries
precisely and that, in the event of any such failure, any Holder may obtain such
relief as may be required to specifically enforce the Company's obligations
under Section 2(a) and Section 2(b) hereof.

          3. Registration Procedures. In connection with the obligations of the
             -----------------------
Company with respect to the Registration Statements pursuant to Sections 2(a)
and 2(b) hereof, the Company shall use its best reasonable efforts to:

                                       11

<PAGE>

          (a) prepare and file with the SEC a Registration Statement or
     Registration Statements as prescribed by Sections 2(a) and 2(b) hereof
     within the relevant time period specified in Section 2 hereof on the
     appropriate form(s) under the Securities Act, which form(s) (i) shall be
     selected by the Company, (ii) shall, in the case of a Shelf Registration,
     be available for the sale of the Registrable Notes by the selling Holders
     thereof and (iii) shall comply as to form in all material respects with the
     requirements of the applicable form and include all financial statements
     required by the SEC to be filed therewith; and use its reasonable best
     efforts to cause such Registration Statement to become effective and remain
     effective in accordance with Section 2 hereof; provided, however, that if
                                                    --------  -------
     (1) such filing is pursuant to Section 2(b) or (2) a Prospectus contained
     in an Exchange Offer Registration Statement filed pursuant to Section 2(a)
     is required to be delivered under the Securities Act by any Participating
     Broker-Dealer who seeks to sell Exchange Notes, before filing any
     Registration Statement or Prospectus or any amendments or supplements
     thereto, the Company shall furnish to and afford the Holders of the
     Registrable Notes and each such Participating Broker-Dealer, as the case
     may be, covered by such Registration Statement, their counsel and the
     managing underwriters, if any, a reasonable opportunity to review copies of
     all such documents (including copies of any documents to be incorporated by
     reference therein and all exhibits thereto) proposed to be filed. The
     Company shall not file any Registration Statement or Prospectus or any
     amendments or supplements thereto in respect of which the Holders must be
     afforded an opportunity to review prior to the filing of such document if
     the Majority Holders or such Participating Broker-Dealer, as the case may
     be, their counsel or the managing underwriters, if any, shall reasonably
     object;

          (b) prepare and file with the SEC such amendments and post-effective
     amendments to each Registration Statement as may be necessary to keep such
     Registration Statement effective for the Effectiveness Period or the
     Applicable Period, as the case may be, and cause each Prospectus to be
     supplemented, if so determined by the Company or requested by the SEC, by
     any required prospectus supplement and as so supplemented to be filed
     pursuant to Rule 424 (or any similar provision then in force) under the
     Securities Act, and comply with the provisions of the Securities Act, the
     Exchange Act and the rules and regulations promulgated thereunder
     applicable to it with respect to the disposition of all securities covered
     by each Registration Statement during the Effectiveness Period or the
     Applicable Period, as the case may be, in accordance with the intended
     method or methods of distribution by the selling Holders thereof described
     in this Agreement (including sales by any Participating Broker-Dealer);

          (c) in the case of a Shelf Registration, (i) notify each Holder of
     Registrable Notes included in the Shelf Registration Statement, at least
     three Business Days prior to filing, that a Shelf Registration Statement
     with respect to the Registrable Notes is being filed and advise such Holder
     that the distribution of Registrable Notes will be made in accordance with
     the method selected by the Majority Holders; (ii) furnish to each Holder of
     Registrable Notes included in the Shelf Registration Statement and to each
     underwriter of an underwritten offering of Registrable Notes, if any, as
     many copies of each Prospectus, including each preliminary Prospectus, and
     any amendment or supplement

                                       12

<PAGE>

     thereto and such other documents as such Holder or underwriter may
     reasonably request, in each case without charge in order to facilitate the
     public sale or other disposition of the Registrable Notes; and (iii)
     consent to the use of the Prospectus or any amendment or supplement thereto
     by each of the selling Holders of Registrable Notes included in the Shelf
     Registration Statement in connection with the offering and sale of the
     Registrable Notes covered by the Prospectus or any amendment or supplement
     thereto.

          (d) in the case of a Shelf Registration, cooperate with the Trustee to
     register or qualify the Registrable Notes under all applicable state
     securities or "blue sky" laws of such jurisdictions by the time the
     applicable Registration Statement is declared effective by the SEC as any
     Holder of Registrable Notes covered by a Registration Statement and each
     underwriter of an underwritten offering of Registrable Notes shall
     reasonably request in writing in advance of such date of effectiveness;
     provided, however, that in complying with the requirements of this Section
     --------  -------
     3(d) the Company shall not be required to (i) qualify as a foreign
     corporation or as a dealer in securities in any jurisdiction where it would
     not otherwise be required to qualify but for this Section 3(d), (ii) file
     any general consent to service of process in any jurisdiction where it
     would not otherwise be subject to such service of process or (iii) file
     annual reports or comply with any other requirements deemed by the Company
     to be unduly burdensome;

          (e) in the case of (1) a Shelf Registration or (2) Participating
     Broker-Dealers from whom the Company has received prior written notice that
     they will be utilizing the Prospectus contained in the Exchange Offer
     Registration Statement as provided in Section 3(t) hereof, are seeking to
     sell Exchange Notes and are required to deliver Prospectuses, promptly
     notify each Holder of Registrable Notes, or such Participating
     Broker-Dealers, as the case may be, their counsel and the managing
     underwriters, if any, and promptly confirm such notice in writing (i) when
     a Registration Statement has become effective and when any post-effective
     amendments and supplements thereto become effective, (ii) of any request by
     the SEC or any state securities authority for amendments and supplements to
     a Registration Statement or Prospectus or for additional information after
     the Registration Statement has become effective, (iii) of the issuance by
     the SEC or any state securities authority of any stop order suspending the
     effectiveness of a Registration Statement or the qualification of the
     Registrable Notes or the Exchange Notes to be offered or sold by any
     Participating Broker-Dealer in any jurisdiction described in paragraph 3(d)
     hereof, (iv) of the happening of any event or the failure of any event to
     occur or the discovery of any fact or otherwise, during the Effectiveness
     Period that makes any statement made in such Registration Statement or the
     related Prospectus untrue in any material respect or that causes such
     Registration Statement or Prospectus to omit to state a material fact
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading, and (v) the Company's
     reasonable determination that a post-effective amendment to the
     Registration Statement would be appropriate;

          (f) make every reasonable effort to obtain the withdrawal of any order
     suspending the effectiveness of a Registration Statement at the earliest
     possible moment;

                                       13

<PAGE>

          (g) in the case of a Shelf Registration, furnish to each Holder of
     Registrable Notes included within the coverage of such Shelf Registration
     Statement, without charge, at least one conformed copy of each Registration
     Statement relating to such Shelf Registration and any post-effective
     amendment thereto (without documents incorporated therein by reference or
     exhibits thereto, unless requested);

          (h) in the case of a Shelf Registration, cooperate with the selling
     Holders of Registrable Notes to facilitate the timely preparation and
     delivery of certificates representing Registrable Notes to be sold and not
     bearing any restrictive legends and in such denominations (consistent with
     the provisions of the Indenture) and registered in such names as the
     selling Holders or the underwriters may reasonably request prior to the
     closing of any sale of Registrable Notes pursuant to such Shelf
     Registration Statement;

          (i) in the case of a Shelf Registration or an Exchange Offer
     Registration, upon the occurrence of any circumstance contemplated by
     Section 3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, prepare a
     supplement or post-effective amendment to a Registration Statement or the
     related Prospectus or any document incorporated therein by reference or
     file any other required document so that, as thereafter delivered to the
     purchasers of the Registrable Notes, such Prospectus will not contain any
     untrue statement of a material fact or omit to state a material fact
     necessary to make the statements therein, in the light of the circumstances
     under which they were made, not misleading; and to notify each Holder to
     suspend use of the Prospectus as promptly as practicable after the
     occurrence of such an event, and each Holder hereby agrees to suspend use
     of the Prospectus until the Company has amended or supplemented the
     Prospectus to correct such misstatement or omission;

          (j) in the case of a Shelf Registration, a reasonable time prior to
     the filing of any document that is to be incorporated by reference into a
     Registration Statement or a Prospectus after the initial filing of a
     Registration Statement, provide a reasonable number of copies, without
     charge, of such document to the Holders; and make such of the
     representatives of the Company as shall be reasonably requested by the
     Holders of Registrable Notes or the Initial Purchasers on behalf of such
     Holders available for reasonable discussion of such document;

          (k) obtain a CUSIP number for all Exchange Notes and the Notes, as the
     case may be, not later than the effective date of a Registration Statement,
     and provide the Trustee with printed certificates for the Exchange Notes or
     the Registrable Notes, as the case may be, in a form eligible for deposit
     with the Depositary;

          (1) cause the Indenture to be qualified under the Trust Indenture Act
     of 1939, as amended (the "TIA") in connection with the registration of the
     Exchange Notes or Registrable Notes, as the case may be, and effect such
     changes to such document as may be required for it to be so qualified in
     accordance with the terms of the TIA and execute, and use its reasonable
     best efforts to cause the Trustee to execute, all documents as may

                                       14

<PAGE>

     be required to effect such changes, and all other forms and documents
     required to be filed with the SEC to enable such document to be so
     qualified in a timely manner;

          (m) in the case of a Shelf Registration, enter into such agreements
     (including underwriting agreements) consistent with the terms of the
     Purchase Agreement and take all such other appropriate actions as are
     reasonably requested in order to expedite or facilitate the registration or
     the disposition of such Registrable Notes, and in such connection, whether
     or not an underwriting agreement is entered into and whether or not the
     registration is an underwritten registration, if requested by (x) any
     Initial Purchaser, in the case where an Initial Purchaser holds Notes
     acquired by it as part of its initial distribution and (y) other Holders of
     Notes covered thereby: (i) make such representations and warranties to
     Holders of such Registrable Notes and the underwriters (if any) consistent
     with the terms of the Purchase Agreement and the registration requirements
     of the Securities Act; (ii) obtain opinions of counsel to the Company and
     updates thereof (which may be in the form of a reliance letter) consistent
     with the terms of the Purchase Agreement and the registration requirements

     such opinion may be subject to customary qualifications and exceptions);
     (iii) obtain "cold comfort" letters and updates thereof in form and
     substance reasonably satisfactory to the managing underwriters from the
     independent certified public accountant of the Company (and, if necessary,
     any other independent certified public accountants of any subsidiary of the
     Company or of any business acquired by the Company for which financial
     statements and financial data are, or are required to be, included in the
     Registration Statement), addressed to each of the underwriters, such
     letters to be in customary form and covering matters of the type
     customarily covered in "cold comfort" letters in connection with
     underwritten offerings and such other matters as reasonably requested by
     such underwriters in accordance with Statement on Auditing Standards No.
     72; and (iv) if an underwriting agreement is entered into, the same shall
     contain indemnification provisions and procedures no less favorable than
     those set forth in Section 4 hereof (or such other provisions and
     procedures acceptable to the Majority Holders of Registrable Notes covered
     by such Registration Statement and the managing underwriters or agents)
     with respect to all parties to be indemnified pursuant to said Section
     (including such underwriters and selling Holders). The above shall be done
     at each closing under such underwriting agreement, or as and to the extent
     required thereunder and as consistent with the terms of the Purchase
     Agreement;

          (n) if (1) a Shelf Registration is filed pursuant to Section 2(b) or
     (2) a Prospectus contained in an Exchange Offer Registration Statement
     filed pursuant to Section 2(a) is required to be delivered under the
     Securities Act by any Participating Broker-Dealer who seeks to sell
     Exchange Notes during the Applicable Period, make reasonably available for
     inspection by any selling Holder of such Registrable Notes being sold, or
     each such Participating Broker-Dealer, as the case may be, any underwriter
     participating in any such disposition of Registrable Notes, if any, and any
     attorney, accountant or other agent retained by any such selling Holder or
     each such Participating Broker-Dealer, as the case may be, or underwriter
     (collectively, the "Inspectors"), at the offices where normally kept,
     during reasonable business hours, financial and other

                                       15

<PAGE>

     records and pertinent corporate documents of the Company and its
     subsidiaries (collectively, the "Records") as shall be reasonably necessary
     to enable them to exercise any applicable due diligence responsibilities,
     and cause the officers, directors and employees of the Company and its
     subsidiaries to supply any relevant information in each case reasonably
     requested by any such Inspector in connection with such Registration
     Statement; provided, further, 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 you and on
     behalf of such other parties as described in Section 2(c) hereof; provided,
                                                                       --------
     however, that such counsel shall be Shearman & Sterling, or such other
     -------
     counsel as is reasonably acceptable to the Company (the "Special Counsel").
     Records that the Company determines in good faith, to be confidential and
     any Records that it notifies the Inspectors are confidential shall not be
     disclosed by the Inspectors. Each selling Holder of such Registrable Notes
     and each such Participating Broker-Dealer will be required to agree in
     writing that information obtained by it as a result of such inspections
     shall be deemed confidential and shall not be used by it as the basis for
     any market transactions in the securities of the Company unless and until
     such is made generally available to the public. Each selling Holder of such
     Registrable Notes and each such Participating Broker-Dealer will be
     required to agree in writing that information obtained by it as a result of
     such inspections shall be deemed confidential and shall not be used by it
     as the basis for any market transactions in the securities of the Company
     unless and until such is made generally available to the public. Each
     selling Holder of such Registrable Notes and each such Participating
     Broker-Dealer will be required to further agree in writing that it will,
     upon learning that disclosure of such Records is sought in a court of
     competent jurisdiction, give notice to the Company and allow the Company at
     its expense to undertake appropriate action to prevent disclosure of the
     Records deemed confidential;

          (o) comply with applicable rules and regulations of the SEC so long as
     this Agreement shall be applicable and make generally available to its
     security holders earning statements satisfying the provisions of Section
     11(a) of the Securities Act and Rule 158 thereunder (or any similar rule
     promulgated under the Securities Act) no later than 45 days after the end
     of any 12-month period (or 90 days after the end of any 12-month period if
     such period is a fiscal year) (i) commencing at the end of any fiscal
     quarter in which Registrable Notes are sold to underwriters in a firm
     commitment or best efforts underwritten offering and (ii) if not sold to
     underwriters in such an offering, commencing on the first day of the first
     fiscal quarter of the Company after the effective date of a Registration
     Statement, which statements shall cover said 12-month periods;

          (p) upon consummation of an Exchange Offer, if requested by the
     Trustee, obtain an opinion of counsel to the Company addressed to the
     Trustee for the benefit of all Holders of Registrable Notes participating
     in the Exchange Offer that includes an opinion that (i) the Company has
     duly authorized, executed and delivered the Exchange Notes and (ii) each of
     the Exchange Notes constitutes a legal, valid and binding obligation of the
     Company enforceable against the Company in accordance with its terms (in
     each case, with customary exceptions);

                                       16

<PAGE>

          (q) if an Exchange Offer is to be consummated, upon delivery of the
     Registrable Notes by Holders to the Company (or to such other Person as
     directed by the Company) in exchange for the Exchange Notes, the Company
     shall mark, or cause to be marked, on such Registrable Notes delivered by
     such Holders that such Registrable Notes are being canceled in exchange for
     the Exchange Notes and in no event shall such Registrable Notes be marked
     as paid or otherwise satisfied;

          (r) cooperate with each seller of Registrable Notes covered by any
     Registration Statement and each underwriter, if any, participating in the
     disposition of such Registrable Notes and their respective counsel in
     connection with any filings required to be made with the NASD;

          (s) use its reasonable best efforts to take all other steps necessary
     to effect the registration of the Registrable Notes covered by a
     Registration Statement contemplated hereby;

          (t) (A) in the case of the Exchange Offer Registration Statement (i)
     indicate in a "Plan of Distribution" section contained in the Prospectus
     contained in the Exchange Offer Registration Statement that any broker or
     dealer registered under the Exchange Act who holds Notes that are
     Registrable Notes and that were acquired for its own account as a result of
     market-making activities or other trading activities (other than
     Registrable Notes acquired directly from the Company) (such broker or
     dealer, a "Participating Broker-Dealer"), may exchange such Notes pursuant
     to the Exchange Offer; however, such Participating Broker-Dealer may be
     deemed to be an "underwriter" within the meaning of the Securities Act and
     must, therefore, deliver a prospectus meeting the requirements of the
     Securities Act in connection with any resales of the Exchange Notes
     received by such Participating Broker-Dealer in the Exchange Offer, which
     prospectus delivery requirement may be satisfied by the delivery by such
     Participating Broker-Dealer of the Prospectus contained in the Exchange
     Offer Registration Statement. Such "Plan of Distribution" section shall
     also contain all other information with respect to such resales by
     Participating Broker-Dealers that the SEC may require in order to permit
     such resales pursuant thereto, but such "Plan of Distribution" shall not
     name any such Participating Broker-Dealer or disclose the amount of
     Exchange Notes held by any such Participating Broker-Dealer except to the
     extent required by the SEC as a result of a change in policy announced
     after the date of this Agreement, (ii) furnish to each Participating
     Broker-Dealer who has delivered to the Company the notice referred to in
     Section 3(e), without charge, as many copies of each Prospectus included in
     the Exchange Offer Registration Statement, including any preliminary
     prospectus, and any amendment or supplement thereto, as such Participating
     Broker-Dealer may reasonably request, (iii) use its reasonable best 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 under the
     Securities Act and applicable rules and regulations in

     order to resell the Exchange Notes; provided, however, that such period
                                         --------  -------
     shall not be required to exceed 90 days (or such longer period if extended
     pursuant to the last sentence of Section 3 hereof) (the "Applicable
     Period"), and (iv) include in the transmittal letter or similar
     documentation to be executed by an exchange offeree in order to participate
     in the Exchange Offer (x) the following provision:

          "If the exchange offeree is a broker-dealer holding Registrable Notes
          acquired for its own account as a result of market-making activities
          or other trading activities, it will deliver a prospectus meeting the
          requirements of the Securities Act in connection with any resale of
          Exchange Notes received in respect of such Registrable Notes pursuant
          to the Exchange Offer";

     and (y) a statement to the effect that by a broker-dealer making the
     acknowledgment described in clause (x) and by delivering a Prospectus in
     connection with the exchange of Registrable Notes, the broker-dealer will
     not be deemed to admit that it is an underwriter within the meaning of the
     Securities Act; and

          (B) in the case of any Exchange Offer Registration Statement, the
     Company agrees to deliver to the Initial Purchasers or to another
     representative of the Participating Broker-Dealers, if requested by any
     such Initial Purchasers or such other representative of the Participating
     Broker-Dealers, on behalf of the Participating Broker-Dealers upon
     consummation of the Exchange Offer (i) an opinion of counsel in form and
     substance reasonably satisfactory to the Initial Purchasers or such other
     representative of the Participating Broker-Dealers, consistent with the
     opinion delivered pursuant to the Purchase Agreement (it being agreed that
     the matters to be covered by such opinion may be subject to customary
     qualifications and exceptions), (ii) an officer's certificate containing
     certifications substantially similar to those set forth in Section 4(b) of
     the Purchase Agreement and (iii) as well as upon the effectiveness of the
     Exchange Offer Registration Statement, a comfort letter, in each case, in
     customary form if permitted by Statement on Auditing Standards No. 72.

          Each of the foregoing shall be consistent with the terms of the
Purchase Agreement.

          The Company may require each seller of Registrable Notes as to which
any registration is being effected to furnish to the Company such information
regarding such seller as may be required by the staff of the SEC to be included
in a Registration Statement. The Company may exclude from such registration the
Registrable Notes of any seller who unreasonably fails to furnish such
information within a reasonable time after receiving such request. The Company
shall have no obligation to register under the Securities Act the Registrable
Notes of a seller who so fails to furnish such information.

          In the case of (1) a Shelf Registration Statement or (2) Participating
Broker-Dealers who have notified the Company that they will be utilizing the
Prospectus contained in the Exchange Offer Registration Statement as provided in
Section 3(t) hereof, are seeking to sell Exchange Notes and are required to
deliver Prospectuses, each Holder agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section
3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, such Holder will forthwith
discontinue disposition of Registrable Notes pursuant to a Registration
Statement until such Holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 3(i) hereof or until it is advised in
writing (the "Advice") by the Company that the use of the applicable Prospectus
may be resumed, and, if so directed by the Company, such Holder will deliver to
the Company all copies in such Holder's possession of the Prospectus covering
such Registrable Notes or Exchange Notes, as the case may be, current at the
time of receipt of such notice. If the Company shall give any such notice to
suspend the disposition of Registrable Notes or Exchange Notes, as the case may
be, pursuant to a Registration Statement, the Company shall use its best efforts
to file and have declared effective (if an amendment) as soon as practicable an
amendment or supplement to the Registration Statement and shall extend the
period during which such Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days in the period from and
including the date of the giving of such notice to and including the date when
the Company shall have made available to the Holders (x) copies of the
supplemented or amended Prospectus necessary to resume such dispositions or (y)
the Advice.

          4.   Indemnification.
               ---------------

          (a) In connection with any Registration Statement, the Company agrees
     to indemnify and hold harmless each of the Initial Purchasers, each Holder,
     each underwriter who participates in an offering of the Registrable Notes,
     each Participating Broker-Dealer, and each Person, if any, who controls any
     of such parties within the meaning of Section 15 of the Securities Act
     (each a "Company Indemnified Party") against any and all losses, claims,
     damages or liabilities, joint or several, to which they or any of them may
     become subject under the Securities Act or otherwise, and to reimburse the
     Company Indemnified Party for any legal or other expenses incurred by them
     in connection with defending any actions, 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 any
     Prospectus or the Prospectus as amended or supplemented, or arise out of or
     are based upon any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein, in light of the circumstances in which they were made, not
     misleading, except insofar as such losses, claims, damages, liabilities or
     actions arise out of or are based upon any such untrue statement or
     omission or alleged untrue statement or omission that was made in such
     Prospectus, or the Prospectus as amended or supplemented, in reliance upon
     and in conformity with information furnished in writing to the Company by
     such Company Indemnified Party (or, if such Company Indemnified Party is an
     Initial Purchaser, through the Representative of the Initial Purchasers on
     behalf of such Initial Purchaser) for use therein and except that this
     indemnity with respect to the Prospectus shall not inure to the benefit of
     any Company Indemnified Party on account of any losses, claims, damages,

                                       19

<PAGE>

     liabilities or actions arising from the sale of Registrable Notes to any
     person if a copy of the Prospectus, as the same may then be amended or
     supplemented, shall not have been sent or given by or on behalf of such
     Company Indemnified Party to such person with or prior to the written
     confirmation of the sale involved and if the Prospectus (as so amended or
     supplemented) would have corrected the defect giving rise to such loss,
     liability, claim or damage.

          (b) Promptly after receipt by any Company Indemnified Party under
     Section 4(a) of written notice of any loss, claim, damage or liability in
     respect of which indemnity may be sought by it hereunder, such Company
     Indemnified Party will, if a claim is to be made against the Company,
     notify the Company thereof in writing, but the omission so to notify the
     Company will not relieve the Company from any liability (otherwise than
     under Section 4(a) above) that it may have to the Company Indemnified
     Party. Thereafter, the Company Indemnified Party and the Company shall
     consult, to the extent appropriate, with a view to minimizing the cost of
     the Company of its obligations hereunder. In case any Company Indemnified
     Party receives written notice of any loss, claim, damage or liability in
     respect of which indemnity may be sought by it hereunder and it notifies
     the Company thereof, the Company will be entitled to participate therein,
     and to the extent that it may elect by written notice delivered to the
     Company Indemnified Party promptly after receiving the aforesaid notice
     from the Company Indemnified Party, to assume the defense thereof with
     counsel reasonably satisfactory to the Company Indemnified Party; provided,
                                                                       --------
     however, that if the parties against which any loss, claim, damage or
     -------
     liability arises include both the Company Indemnified Party and the Company
     and the Company Indemnified Party shall have reasonably concluded that
     defenses available to it create a conflict of interest for the counsel
     selected by the Company Indemnifying party under the code of professional
     responsibility applicable to such counsel, the Company Indemnified Party
     shall have the right to select one separate counsel to assume such legal
     defenses and otherwise to participate in the defenses of such loss, claim,
     damage or liability on behalf of the Company Indemnified Party. Upon
     receipt by the Company Indemnified Party of notice from the Company of its
     selection so to assume the defense of such loss, claim, damage or liability
     and approval by the Company Indemnified Party of counsel, the Company shall
     not be liable to the Company Indemnified Party under Section 4(a) above for
     any legal or other expenses subsequently incurred by the Company
     Indemnified Party in connection with the defense thereof unless (i) the
     Company Indemnified Party shall have employed such counsel in connection
     with the assumption of legal defenses in accordance with the proviso to the
     next preceding sentence, (ii) the Company shall not have employed and
     continued to employ counsel reasonably satisfactory to the Company
     Indemnified Party to represent the Company Indemnified Party within a
     reasonable time after notice of commencement of the action or (iii) the
     Company shall have authorized in writing the employment of separate counsel
     for the Company Indemnified Party at the expense of the Company. The
     Company shall not, without prior written consent of the Company Indemnified
     Party, effect any settlement of any pending or threatened action in respect
     of which the Company Indemnified Party is or is entitled or subject to be a
     party and the Company Indemnified Party is entitled to indemnity hereunder
     unless such settlement includes an unconditional release of the Company
     Indemnified Party from all liability on any claims that are the subject
     matter of such action. The Company shall not

                                       20

<PAGE>

     be liable for any settlement, compromise or consent to the entry of any
     order adjudicating or otherwise disposing of any loss, claim, damage or
     liability effected without its consent.

          The Company's indemnity agreement contained in this Section 4 shall
     remain in full force and effect regardless of any investigation made by or
     on behalf of any Initial Purchaser or any controlling person, and shall
     survive the Exchange Offer Registration.

          (c) In connection with any Registration Statement, each Holder agrees,
     severally and not jointly, to indemnify and hold harmless the Company, any
     underwriter and the other selling Holders and each of their respective
     directors, officers (including each officer of the Company who signed the
     Registration Statement), employees and agents and each Person, if any, who
     controls the Company, any underwriter or any other selling Holder within
     the meaning of Section 15 of the Securities Act (each a "Holder Indemnified
     Party"), against any and all losses, claims, damages or liabilities, joint
     or several, to which they or any of them may become subject under the
     Securities Act or otherwise, and to reimburse the Holder Indemnified Party
     for any legal or other expenses incurred by them in connection with
     defending any actions, 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 any Prospectus or the
     Prospectus as amended or supplemented, or arise out of or are based upon
     any omission or alleged omission to state therein a material fact required
     to be stated therein or necessary to make the statements therein, in light
     of the circumstances in which they were made, not misleading, insofar as
     such losses, claims, damages, liabilities or actions arise out of or are
     based upon any such untrue statement or omission or alleged untrue
     statement or omission that was made in such Prospectus, or the Prospectus
     as amended or supplemented, in reliance upon and in conformity with
     information furnished in writing to the Company by such Holder Indemnified
     Party (or, if such indemnifying Holder is an Initial Purchaser, through the
     Representative of the Initial Purchasers on behalf of such indemnifying
     Holder) for use therein; provided, that, in the case of a Shelf
     Registration Statement, no such Holder shall be liable for any claims
     hereunder in excess of the amount of net proceeds received by such Holder
     from the sale of Registrable Notes pursuant to such Shelf Registration
     Statement.

          Each Holder's indemnity agreement contained in this Section 4 shall
     remain in full force and effect regardless of any investigation made by or
     on behalf of any the Company or any other Holder or any controlling person,
     and shall survive the Exchange Offer Registration.

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

                                       21

<PAGE>

          6. Selection of Underwriters. The Holders of Registrable Notes covered
             -------------------------
by the Shelf Registration Statement who desire to do so may sell the securities
covered by such Shelf Registration in an underwritten offering. In any such
underwritten offering, the underwriter or underwriters and manager or managers
that will administer the offering may be selected by the Holders of a majority
in aggregate principal amount of the Registrable Notes included in such
offering; provided, however, that such underwriters and managers must be
          --------  -------
satisfactory to the Company.

          7. Miscellaneous.
             -------------

          (a) Rule 144 and Rule l44A. For so long as the Company is subject to
              ----------------------
     the reporting requirements of Section 13 or 15 of the Exchange Act and any
     Registrable Notes remain outstanding, the Company will use its reasonable
     best efforts to file the reports required to be filed by it under the
     Securities Act and Section 13(a) or 15(d) of the Exchange Act and the rules
     and regulations adopted by the SEC thereunder, that if it ceases to be so
     required to file such reports, it will, upon the request of any Holder of
     Registrable Notes (a) make publicly available such information as is
     necessary to permit sales of their securities pursuant to Rule 144 under
     the Securities Act, (b) deliver such information to a prospective purchaser
     as is necessary to permit sales of their securities pursuant to Rule 144A
     under the Securities Act and it will take such further action as any Holder
     of Registrable Notes may reasonably request and (c) take such further
     action that is reasonable in the circumstances, in each case, to the extent
     required from time to time to enable such Holder to sell its Registrable
     Notes without registration under the Securities Act within the limitation
     of the exemptions provided by (i) Rule 144 under the Securities Act, as
     such rule may be amended from time to time, (ii) Rule l44A under the
     Securities Act, as such rule may be amended from time to time, or (iii) any
     similar rules or regulations hereafter adopted by the SEC. Upon the request
     of any Holder of Registrable Notes, the Company will deliver to such Holder
     a written statement as to whether it has complied with such requirements.

          (b) No Inconsistent Agreements. The Company has not entered into nor
              --------------------------
     will the Company on or after the date of this Agreement enter into any
     agreement that is inconsistent with the rights granted to the Holders of
     Registrable Notes 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 other issued and outstanding securities under
     any such agreements.

          (c) Amendments and Waivers. The provisions of this Agreement,
              ----------------------
     including the provisions of this sentence, may not be amended, modified or
     supplemented, and waivers or consents to departures from the provisions
     hereof may not be given unless the Company has obtained the written consent
     of Holders of at least a majority in aggregate principal amount of the
     outstanding Registrable Notes affected by such amendment, modification,
     supplement, waiver or departure. Notwithstanding the foregoing sentence,
     (i) this Agreement may be amended, without the consent of any Holder of
     Registrable Notes, by written agreement signed by the Company and Salomon
     Smith Barney, to cure

                                       22

<PAGE>

     any ambiguity, correct or supplement any provision of this Agreement that
     may be inconsistent with any other provision of this Agreement or to make
     any other provisions with respect to matters or questions arising under
     this Agreement that shall not be inconsistent with other provisions of this
     Agreement, (ii) this Agreement may be amended, modified or supplemented,
     and waivers and consents to departures from the provisions hereof may be
     given, by written agreement signed by the Company and Salomon Smith Barney
     to the extent that any such amendment, modification, supplement, waiver or
     consent is, in their reasonable judgment, necessary or appropriate to
     comply with applicable law (including any interpretation of the staff of
     the SEC) or any change therein and (iii) to the extent any provision of
     this Agreement relates to the Initial Purchasers, such provision may be
     amended, modified or supplemented, and waivers or consents to departures
     from such provisions may be given, by written agreement signed by Salomon
     Smith Barney and the Company.

     Holders hereunder.
