      2. Exchange Offer

(a)   The Company shall file with the SEC, to the extent not prohibited by any
      applicable law or applicable interpretation of the staff of the SEC, a
      Registration Statement (the "Exchange Registration Statement") no later
      than the applicable Filing Date with respect to an offer to exchange (the
      "Exchange Offer") any and all of the Registrable Securities (other than
      the Private Exchange Notes, if any) for a like aggregate principal amount
      of debt securities of the Company that are identical in all material
      respects to the Notes (the "Exchange Notes") (and that are entitled to the
      benefits of the Indenture or a trust indenture that is identical in all
      material respects to the Indenture (other than such changes as are
      necessary to comply with any requirements of the SEC to effect or maintain
      the qualification thereof under the TIA)), except that the Exchange Notes
      (other than Private Exchange Notes, if any) shall have been registered
      pursuant to an effective Registration Statement under the Securities Act
      and shall contain no restrictive legend thereon. The Exchange Offer shall
      comply with all applicable tender offer rules and regulations under the
      Exchange Act. The Company agrees to use its reasonable best efforts to (i)
      cause the Exchange Registration Statement to be declared effective under
      the Securities Act on or before the applicable Effectiveness Date; (ii)
      keep the Exchange Offer open for at least 20 business days (or longer if
      required by applicable law) after the date that notice of the Exchange
      Offer first is mailed to Holders; and (iii) consummate the Exchange Offer
      on or prior to the 230th day following the Closing Date. If after such
      Exchange Registration Statement is declared effective by the SEC, the
      Exchange Offer or the issuance of the Exchange Notes thereunder is delayed
      or suspended by any stop order, injunction or other order or requirement
      of the SEC or any other governmental agency or court, such Exchange
      Registration Statement shall be deemed not to have become effective for
      purposes of this Agreement during the period of such delay or suspension
      until the Exchange Offer may legally resume. Each Holder who participates
      in the Exchange Offer will be required to represent in writing that any
      Exchange Notes received by it will be acquired in the ordinary course of
      its business, that at the time of the consummation of the Exchange Offer
      such Holder will have no arrangement or understanding with any Person to
      participate in the distribution of the Exchange Notes in violation of the
      provisions of the Securities Act and that such Holder is not an affiliate
      of the Company within the meaning of the Securities Act and is not acting
      on behalf of any Persons who could not truthfully make the foregoing
      representations, as well as any additional representations required or
      requested by the SEC or its staff. Upon consummation of the Exchange Offer
      in accordance with this Section 2, the provisions of this Agreement shall
      continue to apply, mutatis mutandis, solely with respect to Registrable
      Securities that are Private Exchange Notes and Exchange Notes held by
      Participating Broker-Dealers (as defined below), and the Company shall
      have no further obligation to register Registrable Securities (other than
      Private Exchange Notes and other than in respect of any Exchange Notes as
      to which clause 2(d)(iv) hereof applies) pursuant to Section 3 hereof. No
      securities other than the Exchange Notes shall be included in the Exchange
      Registration Statement.

(b)   The Company shall include within the Prospectus contained in the Exchange
      Registration Statement a section entitled "Plan of Distribution"
      reasonably acceptable to the Initial Purchasers that shall contain a
      summary statement of the positions taken or policies made by the staff of
      the SEC with respect to the potential "underwriter" status of any
      broker-dealer that is the beneficial


                                       4
<PAGE>

      owner (as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes
      received by such broker-dealer in the Exchange Offer (a "Participating
      Broker-Dealer"), whether such positions or policies have been publicly
      disseminated by the staff of the SEC or such positions or policies
      represent the prevailing views of the staff of the SEC. Such "Plan of
      Distribution" section shall also expressly permit, to the extent permitted
      by applicable policies and regulations of SEC, the use of the Prospectus
      by all Persons subject to the prospectus delivery requirements of the
      Securities Act, including, to the extent permitted by applicable policies
      and regulations of SEC, all Participating Broker-Dealers, and include a
      statement describing the means by which Participating Broker-Dealers may
      resell the Exchange Notes in compliance with the Securities Act.

            The Company shall use its reasonable best efforts to keep the
      Exchange 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 is necessary
      to comply with applicable law in connection with any resale of the
      Exchange Notes; provided, however, that such period shall not exceed 210
      days after the consummation of the Exchange Offer (or such longer period
      if extended pursuant to the last paragraph of Section 5 hereof) (the
      "Applicable Period").

            If, prior to consummation of the Exchange Offer, any of the Initial
      Purchasers holds any Notes acquired by it and having, or that are
      reasonably likely to be determined to have, the status of an unsold
      allotment in the initial distribution, the Company, upon the request of
      any such Initial Purchaser simultaneously with the delivery of the
      Exchange Notes in the Exchange Offer, shall issue and deliver to such
      Initial Purchaser in exchange (the "Private Exchange") for such Notes held
      by such Initial Purchaser a like principal amount of debt securities of
      the Company that are identical in all material respects to the Exchange
      Notes (the "Private Exchange Notes") (and that are issued pursuant to the
      same indenture as the Exchange Notes), except for the placement of a
      restrictive legend on such Private Exchange Notes. If permissible, the
      Private Exchange Notes shall bear the same CUSIP number as the Exchange
      Notes.

            Interest on the Exchange Notes and the Private Exchange Notes will
      accrue from the later of (i)(A) the last interest payment date on which
      interest was paid on the Notes surrendered in exchange therefor or (B) if
      the Notes are surrendered for exchange on a date in a period which
      includes the record date for an interest payment date to occur on or after
      the date of such exchange and as to which interest will be paid, the date
      of such interest payment date or, (ii) if no interest has been paid on the
      Notes, from the Closing Date.

            In connection with the Exchange Offer, the Company shall:

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

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


                                       5
<PAGE>

                  (3) otherwise comply in all material respects with all
      applicable laws, rules and regulations.

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

                  (1) accept for exchange all Notes properly tendered and not
      validly withdrawn pursuant to the Exchange Offer or the Private Exchange;
      and

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

            The Exchange Notes and the Private Exchange Notes may be issued
      under the Indenture or an indenture identical in all material respects to
      the Indenture, which in either event has been qualified under the TIA or
      is exempt from such qualification and shall provide that the Exchange
      Notes shall not be subject to any transfer restrictions and the Private
      Exchange Notes shall be subject to the transfer restrictions set forth or
      referred to in the restrictive legend placed on such Private Exchange
      Notes. The Indenture or such indenture shall provide that the Exchange
      Notes, the Private Exchange Notes and the Notes shall vote and consent
      together on all matters as one class and that neither the Exchange Notes,
      the Private Exchange Notes nor the Notes will have the right to vote or
      consent as a separate class on any matter.

(c)   If, following the date hereof there is announced a change in SEC policy
      with respect to exchange offers such as the Exchange Offer, that in the
      reasonable opinion of counsel to the Company raises a substantial question
      as to whether the Exchange Offer is permitted by applicable federal law,
      the Company hereby agrees to seek a no-action letter or other favorable
      decision from the SEC allowing the Company to consummate an Exchange Offer
      for the Notes. The Company hereby agrees to pursue the issuance of such a
      decision to the level of the senior staff of the SEC. In connection with
      the foregoing, the Company hereby agrees to take all such other actions as
      may be requested by the SEC or its staff or otherwise required in
      connection with the issuance of such decision, including without
      limitation (i) participating in telephonic conferences with the SEC, (ii)
      delivering to the SEC or its staff an analysis prepared by counsel to the
      Company setting forth the legal bases, if any, upon which such counsel has
      concluded that such an exchange offer should be permitted and (iii)
      diligently pursuing a resolution (which need not be favorable) by the SEC
      or its staff.

(d)   If, (i) notwithstanding the efforts contemplated in Section 2(c) above,
      the Company is not permitted to effect an Exchange Offer, (ii) the holder
      of Private Exchange Notes so requests within 20 business days after the
      consummation of the Private Exchange, (iii) because of any changes in law
      or in currently prevailing interpretations of the staff of the SEC, a
      Holder (other than an Initial Purchaser holding Notes acquired directly
      from the Company) is not permitted to participate in the Exchange Offer
      and requests the Company in writing within 20 business days after the
      consummation of the Exchange Offer to have such Holder's Notes included in
      a Registration Statement, or (iv) in the case of any Holder that
      participates in the Exchange Offer, such Holder does not receive Exchange
      Notes on the date of the exchange that may be sold without restriction
      under state and federal securities laws (other than due solely to the
      status of


                                       6
<PAGE>

      such Holder as an affiliate of the Company within the meaning of the
      Securities Act) and such Holder requests the Company in writing within 20
      business days after the consummation of the Exchange Offer to have such
      Holder's Exchange Notes included in a Registration Statement), then the
      Company shall promptly deliver written notice thereof (the "Shelf Notice")
      to the Trustee and the affected Holder(s), and shall file a Shelf
      Registration Statement pursuant to Section 3 hereof.

      3. Shelf Registration Statement

            If a Shelf Notice is delivered as contemplated by Section 2(d)
      hereof, then:

(a)   Shelf Registration Statement. The Company shall file with the SEC a
      Registration Statement for an offering to be made on a continuous basis
      pursuant to Rule 415 covering all of the Registrable Securities not
      exchanged in the Exchange Offer, Private Exchange Notes and Exchange Notes
      as to which Section 2(d)(iv) is applicable (the "Initial Shelf
      Registration Statement"). The Company shall use its reasonable best
      efforts to file with the SEC the Initial Shelf Registration Statement on
      or prior to the applicable Filing Date. The Initial Shelf Registration
      Statement shall be on Form S-3 or another appropriate form permitting
      registration of such Registrable Securities for resale by Holders in the
      manner or manners designated by them (but not including any underwritten
      offerings). The Company shall not permit any securities other than the
      Registrable Securities to be included in the Initial Shelf Registration
      Statement or any Subsequent Shelf Registration Statement (as defined
      below).

            The Company shall use its reasonable best efforts to cause the
      Initial Shelf Registration Statement to be declared effective under the
      Securities Act on or prior to the applicable Effectiveness Date and to
      keep the Initial Shelf Registration Statement continuously effective under
      the Securities Act until the date that is two years from the Closing Date
      or such shorter period ending when all Registrable Securities covered by
      the Initial Shelf Registration Statement have been sold in the manner set
      forth and as contemplated in the Initial Shelf Registration Statement or,
      if applicable, a Subsequent Shelf Registration Statement, or cease to be
      outstanding or cease to be Registrable Securities (the "Effectiveness
      Period"); provided, however, that the Effectiveness Period in respect of
      the Initial Shelf Registration Statement shall be extended to the extent
      required to permit dealers to comply with the applicable prospectus
      delivery requirements of Rule 174 under the Securities Act and as
      otherwise provided herein.

(b)   Withdrawal of Stop Orders; Subsequent Shelf Registration Statements. If
      the Initial Shelf Registration Statement or any Subsequent Shelf
      Registration Statement ceases to be effective for any reason at any time
      during the Effectiveness Period (other than because of the sale of all of
      the securities registered thereunder), the Company shall use its
      reasonable best efforts to obtain the prompt withdrawal of any order
      suspending the effectiveness thereof, and in any event shall within 20
      business days of such cessation of effectiveness amend such Shelf
      Registration Statement in a manner to obtain the withdrawal of the order
      suspending the effectiveness thereof, or file an additional Shelf
      Registration Statement pursuant to Rule 415 covering all of the
      Registrable Securities covered by and not sold under the Initial Shelf
      Registration Statement or an earlier Subsequent Shelf Registration
      Statement (each, a "Subsequent Shelf Registration Statement"). If a
      Subsequent Shelf Registration Statement is filed, the Company shall use
      its reasonable best efforts to cause the Subsequent Shelf Registration
      Statement to be declared


                                       7
<PAGE>

      effective under the Act as soon as practicable after such filing and to
      keep such subsequent Shelf Registration Statement continuously effective
      for a period equal to the number of days in the Effectiveness Period less
      the aggregate number of days during which the Initial Shelf Registration
      Statement or any Subsequent Shelf Registration Statement was previously
      continuously effective. As used herein the term "Shelf Registration
      Statement" means the Initial Shelf Registration Statement and any
      Subsequent Shelf Registration Statement.

(c)   Supplements and Amendments. The Company shall promptly supplement and
      amend the Shelf Registration Statement if required by the Securities Act
      or if reasonably requested by the Holders (or their counsel) of a majority
      in aggregate principal amount of the Registrable Securities covered by
      such Shelf Registration Statement with respect to the information included
      therein with respect to one or more of such Holders.

      4. Additional Interest

(a)   The Company and the Initial Purchasers agree that the Holders of
      Registrable Securities will suffer damages if the Company fails to fulfill
      its obligations under Section 2 or Section 3 hereof and that it would not
      be feasible to ascertain the extent of such damages with precision.
      Accordingly, the Company agrees to pay, as liquidated damages, additional
      interest on the Notes ("Additional Interest") under the circumstances and
      to the extent set forth below (without duplication):

                  (i) if (A) neither the Exchange Registration Statement nor the
            Initial Shelf Registration Statement has been filed with the SEC on
            or prior to the date that is 90 days after the Closing Date or (B)
            notwithstanding that the Company has consummated or will consummate
            the Exchange Offer, the Company is required to file a Shelf
            Registration Statement and such Shelf Registration Statement is not
            filed on or prior to the applicable Filing Date, then, commencing on
            the day after any such Filing Date, Additional Interest shall accrue
            on the principal amount of the Notes over and above the stated
            interest at a rate of 0.25% per annum for the first 90 days
            immediately following such applicable Filing Date, and such
            Additional Interest rate shall increase by an additional 0.25% per
            annum at the beginning of each subsequent 90-day period;

                  (ii) if (A) neither the Exchange Registration Statement nor
            the Shelf Registration Statement is declared effective by the SEC on
            or prior to the date 180 days after the Closing Date or (B)
            notwithstanding that the Company has consummated or will consummate
            the Exchange Offer, the Company is required to file a Shelf
            Registration Statement and such Shelf Registration Statement is not
            declared effective by the SEC on or prior to the applicable
            Effectiveness Date in respect of such Shelf Registration Statement,
            then, commencing on the day after such Effectiveness Date,
            Additional Interest shall accrue on the principal amount of the
            Notes included or that should have been included in such
            Registration Statement over and above the stated interest at a rate
            of 0.25% per annum for the first 90 days immediately following the
            day after such Effectiveness Date, and such Additional Interest rate
            shall increase by an additional 0.25% per annum at the beginning of
            each subsequent 90-day period; and


                                       8
<PAGE>

                  (iii) if either (A) the Company has not exchanged Exchange
            Notes for all Notes validly tendered in accordance with the terms of
            the Exchange Offer on or prior to the 230th day after the Closing
            Date or (B) if applicable, a Shelf Registration Statement has been
            declared effective and such Shelf Registration Statement ceases to
            be effective at any time prior to the second anniversary of the
            Closing Date (other than after such time as all Notes have been
            disposed of thereunder), then Additional Interest shall accrue on
            the Notes (over and above any interest otherwise payable on the
            Notes) at a rate of 0.25% per annum for the first 90 days commencing
            on (x) the 230th day after the Closing Date, in the case of (A)
            above, or (y) the day such Shelf Registration Statement ceases to be
            effective, in the case of (B) above , and such Additional Interest
            rate shall increase by an additional 0.25% per annum at the
            beginning of each such subsequent 90-day period;

      provided, however, that (1) the Additional Interest rate on the Notes may
      not accrue under more than one of the foregoing clauses (i) through (iii)
      of this Section 4(a) at any one time and at no time shall the aggregate
      amount of Additional Interest accruing exceed at any one time in the
      aggregate 1.00% per annum, and (2) no Additional Interest shall accrue in
      the event that the Company has timely filed an Exchange Offer Registration
      Statement but is unable to complete the Exchange Offer pursuant to Section
      2(c) and has timely delivered a Shelf Notice unless the Company shall
      thereafter fail to satisfy one or more of the time requirements specified
      above in clauses (i) through (iii) of this Section 4(a) for filing and
      effectiveness of the Shelf Registration Statement, in which event
      Additional Interest as specified above shall accrue, subject, however, to
      the foregoing proviso (1) and all Additional Interest shall cease to
      accrue upon the expiration of the second anniversary of the Closing Date;
      and provided, further, that (1) upon the filing of the Exchange
      Registration Statement or a Shelf Registration Statement (in the case of
      clause (i) of this Section 4(a)), (2) upon the effectiveness of the
      Exchange Registration Statement or the Shelf Registration Statement (in
      the case of clause (ii) of this Section 4(a)), or (3) upon the exchange of
      Exchange Notes for all Notes tendered (in the case of clause (iii)(A) of
      this Section 4(a)), or (4) upon the effectiveness of the applicable Shelf
      Registration Statement that had ceased to remain effective (in the case of
      (iii)(B) of this Section 4(a)), or (5) upon such time as there are no
      Registrable Securities outstanding, Additional Interest on the Notes shall
      cease to accrue.

(b)   The Company shall notify the Trustee within three business days after each
      and every date on which an event occurs in respect of which Additional
      Interest is required to be paid pursuant to Section 4(a). Any amounts of
      Additional Interest due pursuant to this Section 4 will be payable in cash
      semi-annually on each February 1 and August 1 (to the holders of record on
      the January 15 and July 15 immediately preceding such dates), commencing
      with the first such date occurring after any such Additional Interest
      commences to accrue. The amount of Additional Interest will be determined
      by multiplying the Additional Interest rate by the principal amount of the
      Registrable Securities, multiplied by a fraction, the numerator of which
      is the number of days the Additional Interest rate was applicable during
      such period (determined on the basis of a 360-day year consisting of
      twelve 30-day months) and the denominator of which is 360.

      5. Registration Procedures

            In connection with the filing of any Registration Statement pursuant
      to Section 2 or 3 hereof, the Company shall effect such registrations to
      permit the sale of the securities covered


                                       9
<PAGE>

      thereby in accordance with the intended method or methods of disposition
      thereof, and pursuant thereto and in connection with any Registration
      Statement filed by the Company hereunder, the Company shall:

(a)   Prepare and file with the SEC prior to the applicable Filing Date, a
      Registration Statement or Registration Statements as prescribed by Section
      2 or 3 hereof, and use its reasonable best efforts to cause each such
      Registration Statement to become effective and remain effective as
      provided herein; provided, however, that, if (i) such filing is pursuant
      to Section 3 hereof or (2) a Prospectus contained in the Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period relating thereto from
      whom the Company has received written notice that it will be a
      Participating Broker-Dealer in the Exchange Offer, 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 Securities covered by such Registration Statement (with
      respect to a Registration Statement filed pursuant to Section 3 hereof) or
      each such Participating Broker-Dealer (with respect to any such
      Registration Statement), as the case may be, and their counsel, a
      reasonable opportunity to review copies of all such documents (excluding
      copies of any documents to be incorporated by reference therein and all
      exhibits thereto) proposed to be filed, in each case at least five
      business days prior to such filing. The Company shall not file any
      Registration Statement or Prospectus or any amendments or supplements
      thereto if the Holders of a majority in aggregate principal amount of the
      Registrable Securities covered by such Registration Statement or their
      counsel shall reasonably object on or prior to the fifth business day
      following receipt of a copy of any Registration Statement or Prospectus or
      any amendment or supplement thereto proposed to be filed.

(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 continuously effective for the Effectiveness Period
      or the Applicable Period, as the case may be; cause the related Prospectus
      to be supplemented by any prospectus supplement required by applicable
      law, and as so supplemented to be filed pursuant to Rule 424 (or any
      similar provisions then in force) promulgated under the Securities Act;
      and comply with the provisions of the Securities Act and the Exchange Act
      applicable to it with respect to the disposition of all securities covered
      by such Registration Statement as so amended or in such Prospectus as so
      supplemented and with respect to the subsequent resale of any securities
      being sold by a Participating Broker-Dealer covered by any such
      Prospectus; the Company shall be deemed not to have used its reasonable
      best efforts to keep a Registration Statement effective during the
      Applicable Period if the Company voluntarily takes any action that would
      result in selling Holders of the Registrable Securities covered thereby or
      Participating Broker-Dealers seeking to sell Exchange Notes not being able
      to sell such Registrable Securities or such Exchange Notes during that
      period, unless such action is required by applicable law or unless the
      Company complies with this Agreement, including without limitation, the
      provisions of Section 5(k) hereof and the last paragraph of this Section
      5.

(c)   If (i) a Shelf Registration Statement is filed pursuant to Section 3
      hereof or (ii) a Prospectus contained in an Exchange Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, notify the selling
      Holders of Registrable Securities, or each such Participating
      Broker-Dealer, as the case may be, and their counsel,


                                       10
<PAGE>

      promptly (but in any event within two business days) and confirm such
      notice in writing: (A) when a Prospectus or any Prospectus supplement or
      post-effective amendment has been filed, and, with respect to a
      Registration Statement or any post-effective amendment, when the same has
      become effective under the Securities Act (including in such notice a
      written statement that any Holder may, upon request, obtain, at the sole
      expense of the Company, one conformed copy of such Registration Statement
      or post-effective amendment including financial statements and schedules,
      documents incorporated or deemed to be incorporated by reference and all
      exhibits); (B) of the issuance by the SEC of any stop order suspending the
      effectiveness of a Registration Statement or of any order preventing or
      suspending the use of any preliminary prospectus or the initiation of any
      proceedings for that purpose; (C) if at any time when a prospectus is
      required by the Securities Act to be delivered in connection with sales of
      the Registrable Securities or resales of Exchange Notes by Participating
      Broker-Dealers the representations and warranties of the Company contained
      in any agreement cease to be true and correct; (D) of the receipt by the
      Company of any notification with respect to the suspension of the
      qualification or exemption from qualification of a Registration Statement
      or any of the Registrable Securities or the Exchange Notes to be sold by
      any Participating Broker-Dealer for offer or sale in any jurisdiction, or
      the initiation or written threat of any proceeding for such purpose; (E)
      of the happening of any event, the existence of any condition or any
      information becoming known that makes any statement made in such
      Registration Statement or related Prospectus or any document incorporated
      or deemed to be incorporated therein by reference untrue in any material
      respect or that requires the making of any changes in or amendments or
      supplements to such Registration Statement, Prospectus or documents so
      that, in the case of the Registration Statement, it will not contain any
      untrue statement of a material fact or omit to state any material fact
      necessary to make the statements therein not misleading, and that in the
      case of the Prospectus, it will not contain any 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 the light of the
      circumstances under which they were made, not misleading; (F) of the
      Company's determination that a post-effective amendment to a Registration
      Statement would be appropriate; and (G) if at any time when a prospectus
      is required by the Securities Act to be delivered in connection with sales
      of the Registrable Securities or resales of Exchange Notes by
      Participating Broker-Dealers, the Company determines, in its reasonable
      judgment, after consultation with counsel, that the continued use of the
      prospectus would require the disclosure of confidential information or
      interfere with any financing, acquisition, reorganization or other
      material transaction involving the Company.

(d)   Use its reasonable best efforts to prevent the issuance of any order
      suspending the effectiveness of a Registration Statement or of any order
      preventing or suspending the use of a Prospectus or suspending the
      qualification (or exemption from qualification) of any of the Registrable
      Securities or the Exchange Notes for sale in any jurisdiction in the
      United States and, if any such order is issued, to use its reasonable best
      efforts to obtain the withdrawal of any such order at the earliest
      practicable moment.

(e)   If a Shelf Registration Statement is filed pursuant to Section 3 and if
      requested by the Holders of a majority in aggregate principal amount of
      the Registrable Securities being sold in connection with an offering, or
      any Participating Broker-Dealer (i) as promptly as practicable incorporate
      in a prospectus or post-effective amendment such information as such
      Holders, any Participating Broker-Dealer or counsel for any of them
      determine is reasonably necessary to be included


                                       11
<PAGE>

      therein, (ii) make all required filings of such prospectus supplement or
      such post-effective amendment as soon as practicable after the Company has
      received notification of the matters to be incorporated in such Prospectus
      or post-effective amendment and (iii) supplement or make amendments to
      such Registration Statement; provided, however, that the Company shall not
      be required to take any action pursuant to this Section 5(e) that would,
      in the opinion of counsel for the Company, violate applicable law.

(f)   If (i) a Shelf Registration Statement is filed pursuant to Section 3
      hereof or (ii) a Prospectus contained in an Exchange Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, furnish to each selling
      Holder of Registrable Securities and to each such Participating
      Broker-Dealer who so requests and to their respective counsel at the sole
      expense of the Company, one conformed copy of such Registration Statement
      or Registration Statements and each post-effective amendment thereto,
      including financial statements and schedules and, if requested, all
      documents incorporated or deemed to be incorporated therein by reference
      and all exhibits.

(g)   If (i) a Shelf Registration Statement is filed pursuant to Section 3
      hereof or (ii) a Prospectus contained in an Exchange Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, deliver to each selling
      Holder of Registrable Securities, or each such Participating
      Broker-Dealer, as the case may be, and their respective counsel, at the
      sole expense of the Company, as many copies of the Prospectus or
      Prospectuses (including each form of preliminary prospectus) and each
      amendment or supplement thereto and any documents incorporated by
      reference therein as such Persons may reasonably request; and, subject to
      the last paragraph of this Section 5, the Company hereby consents to the
      use of such Prospectus and each amendment or supplement thereto by each of
      the selling Holders of Registrable Securities or each such Participating
      Broker-Dealer, as the case may be, and the agents, if any, and dealers, if
      any, in connection with the offering and sale of the Registrable
      Securities covered by, or the sale by Participating Broker-Dealers of the
      Exchange Notes pursuant to, such Prospectus and any amendment or
      supplement thereto.

(h)   Prior to any public offering of Registrable Securities or Exchange Notes
      or any delivery of a Prospectus contained in the Exchange Registration
      Statement by any Participating Broker-Dealer who seeks to sell Exchange
      Notes during the Applicable Period, to use its reasonable best efforts to
      register or qualify and to cooperate with the selling Holders of
      Registrable Securities or each such Participating Broker-Dealer, as the
      case may be, and their respective counsel in connection with the
      registration or qualification (or exemption from such registration or
      qualification) of such Registrable Securities for offer and sale under the
      securities or Blue Sky laws of such jurisdictions within the United States
      as any selling Holder or Participating Broker-Dealer reasonably requests
      in writing; provided, however, that where Exchange Notes held by
      Participating Broker-Dealers or Registrable Securities are offered other
      than through an underwritten offering, the Company agrees to cause its
      counsel to perform Blue Sky investigations and file registrations and
      qualifications required to be filed pursuant to this Section 5(h); use its
      reasonable best efforts to keep each such registration or qualification
      (or exemption therefrom) effective during the period such Registration
      Statement is required to be kept effective and do any and all other acts
      or things reasonably necessary or advisable to enable


                                       12
<PAGE>

      the disposition in such jurisdictions of the Exchange Notes held by
      Participating Broker-Dealers or the Registrable Securities covered by the
      applicable Registration Statement; provided, however, that the Company
      shall not be required to file any general consent to service of process or
      to qualify as a foreign corporation or as a securities dealer in any
      jurisdiction or to subject itself to taxation in respect of doing business
      in any jurisdiction in which it is not otherwise so subject.

(i)   If a Shelf Registration Statement is filed pursuant to Section 3 hereof,
      cooperate with the selling Holders of Registrable Securities to facilitate
      the timely preparation and delivery of certificates representing
      Registrable Securities to be sold, which certificates shall not bear any
      restrictive legends and shall be in a form eligible for deposit with The
      Depository Trust Company; and if such Registrable Securities are to be in
      certificated form, to enable such Registrable Securities to be in such
      denominations and registered in such names as the Holders may request.

(j)   Use its reasonable best efforts to cause the Registrable Securities
      covered by the Registration Statement to be registered with or approved by
      such other governmental agencies or authorities as may be necessary to
      enable the Holders thereof or the Participating Broker-Dealers, if any, to
      consummate the disposition of such Registrable Securities, except as may
      be required solely as a consequence of the nature of such selling Holder's
      business, in which case the Company will cooperate in all reasonable
      respects with the filing of such Registration Statement and the granting
      of such approvals.

(k)   If (i) a Shelf Registration Statement is filed pursuant to Section 3
      hereof or (ii) a Prospectus contained in an Exchange Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, upon the occurrence of
      any event contemplated by Section 5(c)(ii)(E), 5(c)(ii)(F) or 5(c)(ii)(G)
      hereof, as promptly as practicable (in the case of 5(c)(ii)(G) after
      cessation of the condition referred to therein), prepare and (subject to
      Section 5(a) hereof) file with the SEC, at the Company's sole expense, a
      supplement or post-effective amendment to the Registration Statement or a
      supplement to the related Prospectus or any document incorporated or
      deemed to be incorporated therein by reference, or file any other required
      document so that, as thereafter delivered to the purchasers of the
      Registrable Securities being sold thereunder or to the purchasers of the
      Exchange Notes to whom such Prospectus will be delivered by a
      Participating Broker-Dealer, any such Prospectus will not 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,
      in the light of the circumstances under which they were made, not
      misleading.

(l)   Use its reasonable efforts to cause the Registrable Securities covered by
      a Registration Statement or the Exchange Notes, as the case may be, to be
      rated with the appropriate rating agencies, if so requested by the Holders
      of a majority in aggregate principal amount of Registrable Securities
      covered by such Registration Statement or the Exchange Notes, as the case
      may be.

(m)   Prior to the effective date of the first Registration Statement relating
      to the Registrable Securities, (i) provide the Trustee with certificates
      for, or the form of global note with respect to, the Registrable
      Securities or Exchange Notes, as the case may be, in a form eligible for
      deposit


                                       13
<PAGE>

      with The Depository Trust Company and (ii) provide a CUSIP number for the
      Registrable Securities or Exchange Notes, as the case may be.

(n)   If (i) a Shelf Registration Statement is filed pursuant to Section 3
      hereof or (ii) a Prospectus contained in an Exchange Registration
      Statement filed pursuant to Section 2 hereof is required to be delivered
      under the Securities Act by any Participating Broker-Dealer who seeks to
      sell Exchange Notes during the Applicable Period, upon reasonable advance
      notice make available for inspection by any selling Holder of such
      Registrable Securities being sold, or each such Participating
      Broker-Dealer, as the case may be, and any attorney, accountant or other
      agent retained by any such selling Holder or each such Participating
      Broker-Dealer, as the case may be (collectively, the "Inspectors"), at the
      offices where normally kept, during reasonable business hours without
      interfering in the orderly business of the Company, all financial and
      other relevant records, pertinent corporate documents and instruments 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 respective officers, directors
      and employees of the Company and its subsidiaries to supply all
      information reasonably requested by any such Inspector in connection with
      such Registration Statement. Records that the Company determines, in good
      faith, to be confidential and any Records that they notify the Inspectors
      are confidential shall not be disclosed by the Inspectors unless (A) the
      disclosure of such Records is necessary to avoid or correct a material
      misstatement or omission in such Registration Statement, (B) the release
      of such Records is ordered pursuant to a subpoena or other order from a
      court of competent jurisdiction, (C) after giving reasonable prior notice
      to the Company, disclosure of such information is, in the opinion of
      counsel for any Inspector, necessary or advisable in connection with any
      action, claim, suit or proceeding, directly or indirectly, involving or
      potentially involving such Inspector and arising out of, based upon,
      relating to or involving this Agreement or any transactions contemplated
      hereby or arising hereunder or (D) the information in such Records has
      been made generally available to the public. Each selling Holder of such
      Registrable Securities and each such Participating Broker-Dealer will be
      required to agree 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 information is generally available to the public.
      Each selling Holder of such Registrable Securities and each such
      Participating Broker-Dealer will be required to further agree 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 to undertake appropriate action to prevent disclosure of the
      Records deemed confidential at the Company's sole expense.

(o)   Provide an indenture trustee for the Registrable Securities or the
      Exchange Notes, as the case may be, and cause the Indenture or the trust
      indenture provided for in Section 2(a) hereof, as the case may be, to be
      qualified under the TIA not later than the effective date of the Exchange
      Offer or the first Registration Statement relating to the Registrable
      Securities; and in connection therewith, cooperate with the Trustee and
      the Holders of the Registrable Securities, to effect such changes to such
      indenture as may be required for such indenture to be so qualified in
      accordance with the terms of the TIA; and execute, and use its reasonable
      efforts to cause such trustee to execute, all documents as may be required
      to effect such changes and all other forms and documents required to be
      filed with the SEC to enable such indenture to be so qualified in a timely
      manner.


                                       14
<PAGE>

(p)   Comply with all applicable rules and regulations of the SEC 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
      Securities are sold to underwriters in a firm commitment or reasonable
      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.

(q)   Upon consummation of the Exchange Offer, obtain an opinion of counsel to
      the Company, in a form customary for underwritten transactions, addressed
      to the Trustee that the Exchange Notes and the related indenture
      constitute legal, valid and binding obligations of the Company,
      enforceable against the Company in accordance with their respective terms,
      subject to customary exceptions and qualifications. If an Exchange Offer
      or a Private Exchange is to be consummated, upon delivery of the
      Registrable Securities by Holders to the Company (or to such other Person
      as directed by the Company) in exchange for the Exchange Notes or the
      Private Exchange Notes, as the case may be, the Company shall mark, or
      cause to be marked, on such Registrable Securities that such Registrable
      Securities are being cancelled in exchange for the Exchange Notes or the
      Private Exchange Notes, as the case may be; in no event shall such
      Registrable Securities be marked as paid or otherwise satisfied.

(r)   Cooperate with each seller of Registrable Securities covered by any
      Registration Statement and each Participating Broker-Dealer, if any,
      participating in the disposition of such Registrable Securities and their
      respective counsel in connection with any filings required to be made with
      the National Association of Securities Dealers, Inc. (the "NASD").

(s)   Use its reasonable efforts to take all other steps necessary or advisable
      to effect the registration of the Registrable Securities covered by a
      Registration Statement contemplated hereby.

            The Company may require each seller of Registrable Securities as to
      which any registration is being effected to furnish to the Company such
      information regarding such seller and the distribution of such Registrable
      Securities as the Company may, from time to time, reasonably request. The
      Company may exclude from such registration the Registrable Securities of
      any seller so long as such seller fails to furnish such information within
      a reasonable time after receiving such request. Each seller as to which
      any Shelf Registration Statement is being effected agrees to furnish
      promptly to the Company all information required to be disclosed in order
      to make the information previously furnished to the Company by such seller
      not materially misleading.

            If any such Registration Statement refers to any Holder by name or
      otherwise as the Holder of any securities of the Company, then such Holder
      shall have the right to require (i) the insertion therein of language, in
      form and substance reasonably satisfactory to such Holder, to the effect
      that the holding by such Holder of such securities is not to be construed
      as a recommendation by such Holder of the investment quality of the
      securities covered thereby and that such holding does not imply that such
      Holder will assist in meeting any future financial requirements of the
      Company, or (ii) in the event that such reference to such Holder by name
      or


                                       15
<PAGE>

      otherwise is not required by the Securities Act or any similar federal
      statute then in force, the deletion of the reference to such Holder in any
      amendment or supplement to the Registration Statement filed or prepared
      subsequent to the time that such reference ceases to be required.

            Each Holder of Registrable Securities and each Participating
      Broker-Dealer agrees by acquisition of such Registrable Securities or
      Exchange Notes to be sold by such Participating Broker-Dealer, as the case
      may be, that, upon actual receipt of any notice from the Company of the
      happening of any event of the kind described in Sections 5(c)(ii)(B),
      5(c)(ii)(D), 5(c)(ii)(E), 5(c)(ii)(F) or 5(c)(ii)(G) hereof, such Holder
      will forthwith discontinue disposition of such Registrable Securities
      covered by such Registration Statement or Prospectus or Exchange Notes to
      be sold by such Holder or Participating Broker-Dealer, as the case may be,
      until such Holder's or Participating Broker-Dealer's receipt of the copies
      of the supplemented or amended Prospectus contemplated by Section 5(k)
      hereof, or until it is advised in writing (the "Advice") by the Company
      that the use of the applicable Prospectus may be resumed, and has received
      copies of any amendments or supplements thereto. If the Company shall give
      any such notice, each of the Effectiveness Period and the Applicable
      Period shall be extended by the number of days during such periods from
      and including the date of the giving of such notice to and including the
      date when each seller of Registrable Securities covered by such
      Registration Statement or Exchange Notes to be sold by such Participating
      Broker-Dealer, as the case may be, shall have received (i) the copies of
      the supplemented or amended Prospectus contemplated by Section 5(k) hereof
      or (ii) the Advice, provided that the Effectiveness Period and the
      Applicable Period shall not be extended beyond two years after the Closing
      Date.

      6. Registration Expenses

(a)   All fees and expenses incident to the performance of or compliance with
      this Agreement by the Company shall be borne by the Company whether or not
      the Exchange Offer or any Shelf Registration Statement is filed or becomes
      effective, including, without limitation, (i) all registration and filing
      fees (including, without limitation, fees and expenses of compliance with
      state securities or Blue Sky laws (including, without limitation,
      reasonable fees and disbursements of counsel in connection with Blue Sky
      qualifications of the Registrable Securities or Exchange Notes and
      determination of the eligibility of the Registrable Securities or Exchange
      Notes for investment under the laws of such jurisdictions (A) where the
      holders of Registrable Securities are located, in the case of the Exchange
      Notes, or (B) as provided in Section 5(h) hereof, in the case of
      Registrable Securities or Exchange Notes to be sold by a Participating
      Broker-Dealer during the Applicable Period)), (ii) printing and
      duplicating expenses, including, without limitation, expenses of printing
      certificates for Registrable Securities or Exchange Notes in a form
      eligible for deposit with The Depository Trust Company and of printing or
      duplicating Prospectuses if the printing of Prospectuses is requested by
      the Holders of a majority in aggregate principal amount of the Registrable
      Securities included in any Registration Statement or sold by any
      Participating Broker-Dealer, as the case may be, (iii) messenger,
      telephone and delivery expenses, (iv) fees and disbursements of counsel
      for the Company and fees and disbursements of special counsel for the
      sellers of Registrable Securities (subject to the provisions of Section
      6(b) hereof), (v) rating agency fees, if any, and any fees associated with
      making the Registrable Securities or Exchange Notes eligible for trading
      through The Depository Trust Company, (vi) Securities Act liability
      insurance, if the Company desires such insurance, (vii) fees and expenses
      of all other Persons retained by the Company, (viii) internal expenses of


                                       16
<PAGE>

      the Company (including, without limitation, all salaries and expenses of
      officers and employees of the Company performing legal or accounting
      duties), (ix) the expense of any annual audit or "cold comfort" letters,
      (x) the fees and expenses incurred in connection with the listing of the
      securities to be registered on any securities exchange, if applicable, and
      (xi) the expenses relating to printing, word processing and distributing
      of all Registration Statements, underwriting agreements, securities sales
      agreements, indentures and any other documents necessary to comply with
      this Agreement.

(b)   The Company shall (i) reimburse the Holders of the Registrable Securities
      being registered in a Shelf Registration Statement for the reasonable fees
      and disbursements of not more than one counsel chosen by the Holders of a
      majority in aggregate principal amount of the Registrable Securities to be
      included in such Registration Statement, and (ii) reimburse reasonable
      out-of-pocket expenses (other than legal expenses) of Holders of
      Registrable Securities incurred in connection with the registration and
      sale of the Registrable Securities pursuant to a Shelf Registration
      Statement.

      7. Indemnification

(a)   Indemnification by the Company. The Company will indemnify and hold
      harmless each Holder of Registrable Securities included in an Exchange
      Registration Statement and each Holder of Registrable Securities included
      in a Shelf Registration Statement against any losses, claims, damages or
      liabilities, joint or several, to which such Holder may become subject
      under the Securities Act or otherwise, insofar as such losses, claims,
      damages or liabilities (or actions in respect thereof) arise out of or are
      based upon an untrue statement or alleged untrue statement of a material
      fact contained in any Exchange Registration Statement or Shelf
      Registration Statement, as the case may be, under which such Registrable
      Securities were registered under the Securities Act, or any preliminary,
      final or summary prospectus contained therein or furnished by the Company
      to any such Holder, or any amendment or supplement thereto, 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 will reimburse such Holder for any
      legal or other expenses reasonably incurred by them in connection with
      investigating or defending any such action or claim as such expenses are
      incurred; provided, however, that the Company shall not be liable to any
      such Holder (i) to the extent that any such loss, claim, damage or
      liability arises out of or is based upon an untrue statement or alleged
      untrue statement or omission or alleged omission made in such registration
      statement, or preliminary, final or summary prospectus, or amendment or
      supplement thereto, in reliance upon and in conformity with written
      information furnished to the Company by such Holder expressly for use
      therein or (ii) if such Holder sold to the Person asserting the claim the
      Registrable Notes or Exchange Notes that are the subject of such claim
      after receipt of a notice from the Company pursuant to Sections
      5(c)(ii)(D), 5(c)(ii)(E), 5(c)(ii)(F) or 5(c)(ii)(G) hereof and prior to
      receipt of copies of a supplemented or amended Prospectus contemplated by
      Section 5(k) hereof, or an Advice that the use of the applicable
      Prospectus may be resumed.

(b)   Indemnification by the Holders. The Company may require, as a condition to
      including any Registrable Securities in any registration statement filed
      pursuant to Section 3 hereof, that the Company shall have received an
      undertaking reasonably satisfactory to it from each Participating
      Broker-Dealer selling Exchange Notes during the Applicable Period and from
      each Holder,


                                       17
<PAGE>

      severally and not jointly, to (i) indemnify and hold harmless the Company,
      and all other Holders, against any losses, claims, damages or liabilities
      to which the Company or such other Holders may become subject, under the
      Act or otherwise, insofar as such losses, claims, damages or liabilities
      (or actions in respect thereof) arise out of or are based upon an untrue
      statement or alleged untrue statement of a material fact contained in such
      registration statement, or any preliminary, final or summary prospectus
      contained therein or furnished by the Company to any such Holder, or any
      amendment or supplement thereto, 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, in each case to the extent, but only to the extent, that such
      untrue statement or alleged untrue statement or omission or alleged
      omission was made in reliance upon and in conformity with written
      information furnished to the Company by such Holder expressly for use
      therein, and (ii) reimburse the Company for any legal or other expenses
      reasonably incurred by the Company in connection with investigating or
      defending any such action or claim as such expenses are incurred;
      provided, however, that no such Holder shall be required to undertake
      liability to any Person under this Section 7(b) for any amounts in excess
      of the dollar amount of the proceeds to be received by such Holder from
      the sale of such Holder's Registrable Securities pursuant to such
      registration.

(c)   Notices of Claims, Etc. Promptly after receipt by an indemnified party
      under subsection (a) or (b) above of written notice of the commencement of
      any action, such indemnified party shall, if a claim in respect thereof is
      to be made against an indemnifying party pursuant to the indemnification
      provisions of or contemplated by this Section 7, notify such indemnifying
      party in writing of the commencement of such action; but the omission so
      to notify the indemnifying party (i) shall not relieve it from liability
      under Subsection 7(a) or 7(b) hereof unless and to the extent it did not
      otherwise learn of such action and such failure results in the forfeiture
      by the indemnifying party of substantial rights and defenses and (ii)
      shall not, in any event, relieve it from any liability which it may have
      to any indemnified party otherwise than under the indemnification
      provisions of or contemplated by Section 7(a) or 7(b) hereof. In case any
      such action shall be brought against any indemnified party and it shall
      notify an indemnifying party of the commencement thereof, such
      indemnifying party shall be entitled to participate therein and, to the
      extent that it shall wish, jointly with any other indemnifying party
      similarly notified, to assume the defense thereof, with counsel reasonably
      satisfactory to such indemnified party (who shall not, except with the
      consent of the indemnified party, be counsel for the indemnifying party),
      and, after notice from the indemnifying party to such indemnified party of
      its election so to assume the defense thereof, such indemnifying party
      shall not be liable to such indemnified party for any legal expenses of
      other counsel or any other expenses, in each case subsequently incurred by
      such indemnified party, in connection with the defense thereof other than
      reasonable costs of investigation. No indemnifying party shall, without
      the written consent of the indemnified party, effect the settlement or
      compromise of, or consent to the entry of any judgment with respect to,
      any pending or threatened action or claim in respect of which
      indemnification or contribution may be sought hereunder (whether or not
      the indemnified party is an actual or potential party to such action or
      claim) unless such settlement, compromise or judgment (i) includes an
      unconditional release of the indemnified party from all liability arising
      out of such action or claim and (ii) does not include a statement as to or
      an admission of fault, culpability or a failure to act by or on behalf of
      any indemnified party.


                                       18
<PAGE>

(d)   Contribution. If for any reason the indemnification provisions
      contemplated by Section 7(a) or Section 7(b) are unavailable to or
      insufficient to hold harmless an indemnified party in respect of any
      losses, claims, damages or liabilities (or actions in respect thereof)
      referred to therein, then each indemnifying party shall contribute to the
      amount paid or payable by such indemnified party as a result of such
      losses, claims, damages or liabilities (or actions in respect thereof) in
      such proportion as is appropriate to reflect the relative fault of the
      indemnifying party and the indemnified party in connection with the
      statements or omissions which 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 such indemnifying party
      and indemnified party shall be determined by reference to, among other
      things, whether the untrue or alleged untrue statement of a material fact
      or omission or alleged omission to state a material fact relates to
      information supplied by such indemnifying party or by such indemnified
      party, and the parties' relative intent, knowledge, access to information
      and opportunity to correct or prevent such statement or omission. The
      parties hereto agree that it would not be just and equitable if
      contributions pursuant to this Section 7(d) were determined by pro rata
      allocation (even if the Holders were treated as one entity for such
      purpose) or by any other method of allocation which does not take account
      of the equitable considerations referred to in this Section 7(d). The
      amount paid or payable by an indemnified party as a result of the losses,
      claims, damages, or liabilities (or actions in respect thereof) referred
      to above shall be deemed to include any legal or other fees or expenses
      reasonably incurred by such indemnified party in connection with
      investigating or defending any such action or claim. Notwithstanding the
      provisions of this Section 7(d), no Holder shall be required to contribute
      any amount in excess of the amount by which the dollar amount of the
      proceeds received by such Holder from the sale of any Registrable
      Securities (after deducting any fees and commissions applicable thereto)
      exceeds the amount of any damages which such Holder has otherwise been
      required to pay by reason of such untrue or alleged untrue statement or
      omission or alleged omission. No Person guilty of fraudulent
      misrepresentation (within the meaning of Section 11(f) of the Securities
      Act) shall be entitled to contribution from any Person who was not guilty
      of such fraudulent misrepresentation. The Holders' obligations in this
      Section 7(d) to contribute shall be several in proportion to the principal
      amount of Registrable Securities registered by them and not joint.

(e)   The obligations of the Company under this Section 7 shall be in addition
      to any liability which the Company may otherwise have and shall extend,
      upon the same terms and conditions, to each officer, director and partner
      of each Holder and each Person, if any, who controls any Holder within the
      meaning of the Securities Act; and the obligations of the Holders
      contemplated by this Section 7 shall be in addition to any liability which
      the Holder may otherwise have and shall extend, upon the same terms and
      conditions, to each officer and director of the Company and to each
      Person, if any, who controls the Company within the meaning of the
      Securities Act.

      8. Rule 144 and 144A

            The Company covenants that it will file the reports required to be
      filed by it under the Securities Act and the Exchange Act and the rules
      and regulations adopted by the SEC thereunder in a timely manner in
      accordance with the requirements of the Securities Act and the Exchange
      Act and, if at any time the Company is not required to file such reports,
      they will, upon the request of any Holder of Registrable Securities, make
      available to any Holder or beneficial owner of Registrable Securities in
      connection with any sale thereof and any


                                       19
<PAGE>

      prospective purchaser of such Registrable Securities from such Holder or
      beneficial owner the information required by Rule 144A(d)(4) under the
      Securities Act in order to permit resales of such Registrable Securities
      pursuant to Rule 144A. The Company further covenants and agrees, for so
      long as any Registrable Securities remain outstanding, that it will take
      such further action as any Holder of Registrable Securities may reasonably
      request, all to the extent required from time to time to enable such
      holder to sell Registrable Securities without registration under the
      Securities Act within the limitation of the exemptions provided by Rule
      144(k) under the Securities Act and Rule 144A.

      9. Miscellaneous

(a)   No Inconsistent Agreements. The Company has not entered into, as of the
      date hereof, and shall not, after the date of this Agreement, enter into
      any agreement with respect to any of the Company's securities that is
      inconsistent with the rights granted to the Holders of Registrable
      Securities in this Agreement or otherwise conflicts with the provisions
      hereof. The Company has not entered and will not enter into any agreement
      with respect to any of the Company's securities that will grant to any
      Person piggy-back registration rights with respect to a Registration
      Statement.

(b)   Adjustments Affecting Registrable Securities. The Company shall not,
      directly or indirectly, take any action with respect to the Registrable
      Securities as a class that would adversely affect the ability of the
      Holders of Registrable Securities to include such Registrable Securities
      in a registration undertaken pursuant to this Agreement.

(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, otherwise than with the prior
      written consent of the Holders of not less than a majority in aggregate
      principal amount of the then outstanding Registrable Securities.
      Notwithstanding the foregoing, a waiver or consent to depart from the
      provisions hereof with respect to a matter that relates exclusively to the
      rights of Holders of Registrable Securities whose securities are being
      sold pursuant to a Registration Statement and that does not directly or
      indirectly affect, impair, limit or compromise the rights of other Holders
      of Registrable Securities may be given by Holders of at least a majority
      in aggregate principal amount of the Registrable Securities being sold by
      such Holders pursuant to such Registration Statement; provided, however,
      that the provisions of this sentence may not be amended, modified or
      supplemented except in accordance with the provisions of the immediately
      preceding sentence.

(d)   Notices. All notices and other communications (including without
      limitation any notices or other communications to the Trustee) provided
      for or permitted hereunder shall be made in writing by hand-delivery,
      registered first-class mail, next-day air courier or facsimile:

      MADE AND PERFORMED WHOLLY WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO
      PRINCIPLES OF CONFLICTS OF LAW THAT WOULD RESULT IN THE APPLICATION OF
      ANOTHER STATE'S LAW. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE
      JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR
      PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

(i)   Severability. If any term, provision, covenant or restriction of this
      Agreement is held by a court of competent jurisdiction to be invalid,
      illegal, void or unenforceable, the remainder of the terms, provisions,
      covenants and restrictions set forth herein shall remain in full force and
      effect and shall in no way be affected, impaired or invalidated, and the
      parties hereto shall use their reasonable best efforts to find and employ
      an alternative means to achieve the same or substantially the same result
      as that contemplated by such term, provision, covenant or restriction. It
      is hereby stipulated and declared to be the intention of the parties that
      they would have executed the remaining terms, provisions, covenants and
      restrictions without including any of such that may be hereafter declared
      invalid, illegal, void or unenforceable.

(j)   Notes Held by the Company or its Affiliates. Whenever the consent or
      approval of Holders of a specified percentage of Registrable Securities is
      required hereunder, Registrable Securities held by the Company or its
      affiliates (as such term is defined in Rule 405 under the Securities Act)
      shall not be counted in determining whether such consent or approval was
      given by the Holders of such required percentage.

(k)   Third Party Beneficiaries. Holders of Registrable Securities and
      Participating Broker-Dealers are intended third party beneficiaries of
      this Agreement and this Agreement may be enforced by such Persons.

(l)   Specific Performance. The parties hereto acknowledge that there would be
      no adequate remedy at law if the Company fails to perform any of its
      obligations hereunder and that the Initial Purchasers, Holders of
      Registrable Securities and Participating Broker-Dealers may be irreparably
      harmed by any such failure, and accordingly agree that the Initial
      Purchasers, Holders of Registrable Securities and Participating
      Broker-Dealers, in addition to any other remedy to which they may be
      entitled at law or in equity, shall be entitled to compel specific
      performance of the obligations of the Company under this Agreement in
      accordance with the terms and conditions of this Agreement, in any court
      of the United States or any State thereof having jurisdiction; provided
      that in the event that the Company fails to perform any terms of this
      Agreement with respect to which Additional Interest pursuant to Section 4
      hereof is expressly


                                       22

      provided as a remedy, and the company is not in default of payment of such
      Additional Interest, payment of such Additional Interest shall constitute
      the sole monetary damages for such failure.

      the Indenture, is intended by the parties as a final and exclusive
