                                       6



                         (iii) that any Registrable Security not tendered will
                  remain outstanding and continue to accrue interest, but will

                          (iv) that Holders electing to have a Registrable

                  the address specified in the notice prior to the close of
                  business on the last Exchange Date; and

                           (v) that Holders will be entitled to withdraw their
                  election, not later than the close of business on the last
                  Exchange Date, by sending to the institution and at the
                  address (located in the Borough of Manhattan, The City of New
                  York) specified in the notice, a telegram, telex, facsimile
                  transmission or letter setting forth the name of such Holder,
                  the principal amount of Registrable Securities delivered for
                  exchange and a statement that such Holder is withdrawing his
                  election to have such Registrable Securities exchanged.

                  As soon as practicable after the last Exchange Date, the
         Company shall:


                                    (A) accept for exchange Registrable
                           Securities or portions thereof tendered and not
                           validly withdrawn pursuant to the Exchange Offer; and

                                    (B) deliver, or cause to be delivered, to
                           the Trustee for cancellation all Registrable
                           Securities or portions thereof so accepted for
                           exchange by the Company and issue, and cause the
                           Trustee to promptly authenticate and mail to each
                           Holder, an Exchange Security equal in aggregate
                           principal amount to the aggregate principal amount of
                           the Registrable Securities surrendered by such
                           Holder.

                  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 1933 Act, the 1934 Act and other
         applicable laws and regulations in connection with the Exchange Offer.
         The Exchange Offer shall not be subject to any conditions, other than
         that the Exchange Offer does not violate applicable law or any
         applicable interpretation of the Staff of the SEC. The Company shall
         inform the Initial Purchasers of the names


                                       7


         and addresses of the Holders to whom the Exchange Offer is made, and
         the Initial Purchasers shall have the right, subject to applicable law,
         to contact such Holders and otherwise facilitate the tender of
         Registrable Securities in the Exchange Offer.


                  If, during the period the Exchange Offer Registration
         Statement is effective, an event occurs which makes any statement made
         in such Exchange Offer Registration Statement or the related Prospectus
         untrue in any material respect or which requires the making of any
         changes in such Exchange Offer Registration Statement or Prospectus in
         order to make the statements therein not misleading, the Company shall
         use its reasonable best efforts to prepare and file with the SEC a
         supplement or post-effective amendment to the Exchange Offer
         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
         Securities, 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 light of the circumstances under which they were
         made, not misleading. The Company agrees to notify the Holders to
         suspend the exchange of the Registrable Securities as promptly as
         practicable after the occurrence of such an event, and the Holders
         hereby agree to suspend such exchange until the Company has amended or
         supplemented the Prospectus to correct such misstatement or omission.

                  (b) If (i) the Company determines that the Exchange Offer
         Registration provided for in Section 2(a) above is not available or may
         not be consummated as soon as practicable after the last Exchange Date
         because it would violate applicable law or the applicable
         interpretations of the Staff of the SEC, (ii) the Exchange Offer is not
         for any other reason consummated within 180 days following the Closing
         Date or (iii) in the written opinion of counsel for the Holders a Shelf
         Registration Statement must be filed and a Prospectus must be delivered
         by any Holder in connection with any reoffering or resale of
         Registrable Securities, the Company shall (x) file with the SEC within
         75 days following such determination, date or notice of such opinion of
         counsel is given to the Company a Shelf Registration Statement
         providing for the resale by the Holders (other than those who fail to
         comply with the paragraph immediately following clause (p) of Section
         3) of all of their Registrable Securities and (y) use its reasonable
         best efforts to cause such Shelf Registration Statement to become
         effective within 60 days thereafter. If the Company is required to file
         a Shelf Registration Statement solely as a result of the matters
         referred to in clause (iii) of the preceding sentence, the Company
         shall use its reasonable best efforts to file and have declared
         effective by the SEC both an Exchange Offer Registration Statement
         pursuant to Section 2(a) with respect to all Registrable Securities and
         a




                                       8


         Shelf Registration Statement (which may be a combined Registration
         Statement with the Exchange Offer Registration Statement) with respect
         to reoffers and resales of Registrable Securities held by the Holders
         who must deliver the related Prospectus. The Company agrees to use its
         reasonable best efforts to keep the Shelf Registration Statement
         continuously effective until the expiration of the period referred to
         in Rule 144(k) with respect to the Registrable Securities or such
         shorter period that will terminate when all of the Registrable
         Securities covered by the Shelf Registration Statement have been sold
         pursuant to the Shelf Registration Statement or cease to be Registrable
         Securities within the meaning of this Agreement. The Company further
         agrees 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 1933 Act or by any other rules and regulations
         thereunder for shelf registration or if reasonably requested by a
         Holder with respect to information relating to such Holder, and to use
         its reasonable best efforts to cause any such amendment to become
         effective and such Shelf Registration Statement to become usable as
         soon as thereafter practicable. 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) The Company shall pay all Registration Expenses in
         connection with the registration pursuant to Section 2(a) or Section
         2(b). Each Holder shall pay all underwriting discounts, if any, and
         commissions and transfer taxes, if any, relating to the sale or
         disposition of such Holder's Registrable Securities pursuant to a Shelf
         Registration Statement.

                  (d) An Exchange Offer Registration Statement pursuant to
         Section 2(a) hereof or a Shelf Registration Statement pursuant to
         Section 2(b) hereof will not be deemed to have become effective unless
         it has been declared effective by the SEC; provided, however, that, if,
         after it has been declared effective, the offering of Registrable
         Securities pursuant to a Shelf Registration Statement is interfered
         with by any stop order, injunction or other order or requirement of the
         SEC or any other governmental agency or court, such Registration
         Statement will be deemed not to have become effective during the period
         of such interference until the offering of Registrable Securities
         pursuant to such Registration Statement may legally resume.

                  (e) The Company and the Initial Purchasers agree that the
         Holders will suffer damages if the Company fails to fulfill its
         obligations under Section 2(a) or Section 2(b) hereof and that it would
         not be feasible to ascertain the extent of such damages with precision.
         Accordingly, the Company agrees that if:


                                       9



                           (i) the Exchange Offer Registration Statement is not
                  filed with the SEC on or prior to the 75th day following the
                  Closing Date,

                           (ii) the Exchange Offer Registration Statement is not
                  declared effective on or prior to the 120th day following the
                  Closing Date,

                           (iii) the Exchange Offer is not completed on or prior
                  to the 180th day following the Closing Date, or

                           (iv) the Shelf Registration Statement is required to
                  be filed but is not filed or declared effective within the
                  time period set forth herein or is declared effective but
                  thereafter ceases to be effective or usable prior to the
                  expiration of the period referred to in Rule 144(k) with
                  respect to the Registrable Securities other than after the
                  Registrable Securities have been disposed of under the Shelf
                  Registration Statement or cease to be Registrable Securities,
                  without being succeeded within two Business Days by a
                  post-effective amendment which cures the failure and that is
                  itself immediately declared effective,


         (each such event referred to in clauses (i) through (iv) a
         "REGISTRATION DEFAULT"), liquidated damages ("LIQUIDATED DAMAGES") will
         accrue on the affected Registrable Securities and the affected Exchange
         Securities, as applicable. The rate of Liquidated Damages will be 0.25%
         per annum of the principal amount of Registrable Securities held by
         such Holder for the first 90-day period immediately following the
         occurrence of a Registration Default, increasing to 0.50% per annum
         thereafter, from and including the date on which any such Registration
         Default shall occur to, but excluding, the earlier of (1) the date on
         which all Registration Defaults have been cured or (2) the date on
         which all the Registrable Securities and Exchange Securities otherwise
         become freely transferable by Holders other than affiliates of the
         Securities without further registration under the 1933 Act.

                  Notwithstanding the foregoing, (1) the amount of Liquidated
         Damages payable shall not increase because more than one Registration
         Default has occurred and is pending and (2) a Holder of Registrable
         Securities or Exchange Securities who is not entitled to the benefits
         of the Shelf Registration Statement (i.e., such Holder has not elected
         to including information) shall not be entitled to Liquidated Damages
         with respect to a Registration Default that pertains to the Shelf
         Registration Statement.


                                       10



                  (f) The Company shall notify the Trustee within one Business
         Day after each date on which an event occurs in respect of which
         Liquidated Damages are required to be paid. Any amounts of Liquidated
         Damages due pursuant to this Section 2 will be payable in addition to
         any other interest payable from time to time with respect to the
         Registrable Securities in cash semi-annually on the interest payment
         dates specified in the Indenture (to the holders of record as specified
         in the Indenture), commencing with the first such interest payment date
         occurring after any such Liquidated Damages commence to accrue. The
         amount of Liquidated Damages will be determined in a manner consistent
         with the calculation of interest under the Indenture.

                  (g) 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 will not be possible to measure damages
         for such injuries precisely and that, in the event of any such failure,
         the Initial Purchasers or any Holder may obtain such relief as may be
         required to specifically enforce the Company's obligations under
         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 Section 2(a) and Section 2(b) hereof, the
Company shall as expeditiously as possible (provided, however, that the Company
shall not be required to take actions more promptly than required by Sections
2(a) and 2(b)):

                  (a) prepare and file with the SEC a Registration Statement on
         the appropriate form under the 1933 Act, which form shall (x) be
         selected by the Company, (y) in the case of a Shelf Registration, be
         available for the sale of the Registrable Securities by the selling
         Holders thereof and (z) comply as to form in all material respects with
         the applicable requirements of the 1933 Act and rules and regulations
         promulgated thereunder and include all financial statements required by
         the SEC to be filed therewith, and use reasonable best efforts to cause
         such Registration Statement to become effective and remain effective in
         accordance with Section 2 hereof;

                  (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
         applicable period and cause each Prospectus to be supplemented by any
         required prospectus supplement and, as so supplemented, to be filed
         pursuant to Rule 424


                                       11


         under the 1933 Act; and keep each Prospectus current during the period
         described under Section 4(3) and Rule 174 under the 1933 Act that is
         applicable to transactions by brokers or dealers with respect to the
         Registrable Securities or Exchange Securities;

                  (c) in the case of a Shelf Registration, furnish to each
         Holder of Registrable Securities, to counsel for the Initial Purchasers
         and to counsel for the Holders and to each Underwriter of an
         Underwritten Offering of Registrable Securities, if any, without
         charge, as many copies of each Prospectus, including each preliminary
         Prospectus and any amendment or supplement thereto and such other
         documents as such Holder or Underwriter may reasonably request, in
         order to facilitate the public sale or other disposition of the
         Registrable Securities; and, subject to Section 3(i), the Company
         consents to the use of such Prospectus and any amendment or supplement
         thereto in accordance with applicable law by each of the selling
         Holders of Registrable Securities and any such Underwriters in
         connection with the offering and sale of the Registrable Securities
         covered by and in the manner described in such Prospectus or any
         amendment or supplement thereto in accordance with applicable law;

                  (d) use its reasonable best efforts to register or qualify the
         Registrable Securities under all applicable state securities or blue
         sky laws of such jurisdictions as any Holder of Registrable Securities
         covered by a Registration Statement shall reasonably request in writing
         by the time the applicable Registration Statement is declared effective
         by the SEC, and to cooperate with such Holders in connection with any
         filings required to be made with the National Association of Securities
         Dealers, Inc. and do any and all other acts and things which may be
         reasonably necessary or advisable to enable such Holder to consummate
         the disposition in each such jurisdiction of such Registrable
         Securities owned by such Holder; provided, however, that 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 or (iii) subject itself to taxation in
         any such jurisdiction if it is not so subject;

                  (e) in the case of a Shelf Registration, notify each Holder of
         Registrable Securities, counsel for the Holders and counsel for the
         Initial Purchasers (or, if applicable, separate counsel for the
         Holders) promptly and, if requested by any such Holder or counsel,
         confirm such advice in writing, (i) when a Registration Statement has
         become effective and when any post-effective amendment thereto has been
         filed and becomes effective, (ii) of any request by the SEC or any
         state securities authority for amendments and supplements to a
         Registration Statement and Prospectus or for additional information
         after the Registration Statement has become


                                       12


         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 initiation of any proceedings for that
         purpose, (iv) if, between the effective date of a Registration
         Statement and the closing of any sale of Registrable Securities covered
         thereby, the representations and warranties of the Company contained in
         any underwriting agreement, securities sales agreement or other similar
         agreement, if any, relating to the offering cease to be true and
         correct in all material respects or if the Company receives any
         notification with respect to the suspension of the qualification of the
         Registrable Securities for sale in any jurisdiction or the initiation
         of any proceeding for such purpose, (v) of the happening of any event
         during the period a Shelf Registration Statement is effective which
         makes any statement made in such Shelf Registration Statement or the
         related Prospectus untrue in any material respect or which requires the
         making of any changes in such Registration Statement or Prospectus in
         order to make the statements therein not misleading and (vi) of any
         determination by the Company that a post-effective amendment to a
         Registration Statement would be appropriate;

                  (f) use its reasonable best efforts to obtain the withdrawal
         of any order suspending the effectiveness of a Registration Statement
         at the earliest possible moment and provide immediate notice to each
         Holder of the withdrawal of any such order;

                  (g) in the case of a Shelf Registration, furnish to each
         Holder of Registrable Securities, without charge, at least one
         conformed copy of each Registration Statement 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 Securities to facilitate the timely
         preparation and delivery of certificates representing Registrable
         Securities to be sold and not bearing any restrictive legends (unless
         required by applicable securities laws) and enable such Registrable
         Securities to be in such denominations (consistent with the provisions
         of the Indenture) and registered in such names as the selling Holders
         may reasonably request at least two Business Days prior to the closing
         of any sale of Registrable Securities;

                  (i) in the case of a Shelf Registration, upon the occurrence
         of any event contemplated by Section 3(e)(v) hereof, use its reasonable
         best efforts to prepare and file with the SEC 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




                                       13


         Registrable Securities, 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. The Company agrees to notify the
         Holders to suspend use of the Prospectus as promptly as practicable
         after the occurrence of such an event, and the Holders hereby agree to
         suspend use of the Prospectus until the Company has amended or
         supplemented the Prospectus to correct such misstatement or omission
         and has furnished copies of the amended or supplemented Prospectus to
         the Holders or until the Company notifies the Holders that the sale of
         the Registrable Securities may be resumed;

                  (j) a reasonable time prior to the filing of any Registration
         Statement, any Prospectus, any amendment to a Registration Statement or
         amendment or supplement to a Prospectus, or any document which is to be
         incorporated by reference into a Registration Statement or Prospectus
         after the initial filing of a Registration Statement, provide copies of
         such document to the Initial Purchasers and their counsel (and, in the
         case of a Shelf Registration Statement, the Holders and their counsel)
         and make such of the representatives of the Company as shall be
         reasonably requested by the Initial Purchasers or their counsel (and,
         in the case of a Shelf Registration Statement, the Holders or their
         counsel) available for discussion of such document, and shall not at
         any time file or make any amendment to the Shelf Registration
         Statement, any Prospectus or any amendment of or supplement to a Shelf
         Registration Statement or a Prospectus or any document which is to be
         incorporated by reference into a Registration Statement or a
         Prospectus, of which the Initial Purchasers and their counsel (and, in
         the case of a Shelf Registration Statement, the Holders or their
         counsel) shall not have previously been advised and furnished a copy or
         to which the Initial Purchasers or their counsel (and, in the case of a
         Shelf Registration Statement, the Holders or their counsel) shall
         reasonably object;

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

                  (l) 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 Securities or Registrable Securities, as
         the case may be, and cooperate with the Trustee and the Holders to
         effect such changes to the Indenture as may be required for the
         Indenture to be so qualified in accordance with the terms of the TIA
         and execute, and use commercially reasonable best efforts to cause the
         Trustee to execute, all documents as may be required to effect such
         changes and all other forms and documents


                                       14


         required to be filed with the SEC to enable the Indenture to be so
         qualified in a timely manner;

                  (m) in the case of a Shelf Registration, make available for
         inspection by a representative of the Holders of the Registrable
         Securities, any Underwriter participating in any disposition pursuant
         to such Shelf Registration Statement, and attorneys and accountants
         designated by the Holders, at reasonable times and in a reasonable
         manner, all financial and other records, pertinent documents and
         properties of the Company, and cause the respective officers, directors
         and employees of the Company to supply all information reasonably
         requested by any such representative, Underwriter, attorney or
         accountant in connection with a Shelf Registration Statement, in each
         case that would customarily be reviewed or examined in connection with
         "due diligence" review of the Company;

                  (n) use its reasonable best efforts to cause the Exchange
         Securities to continue to be rated by two nationally recognized
         statistical rating organizations (as such term is defined in Rule
         436(g)(2) under the 1933 Act), if the Registrable Securities have been
         rated;

                  (o) if reasonably requested by any Holder of Registrable
         Securities covered by a Registration Statement, (i) promptly
         incorporate in a Prospectus supplement or post-effective amendment such
         information with respect to such Holder as such Holder reasonably
         requests to be included therein and (ii) make all required filings of
         such Prospectus supplement or such post-effective amendment as soon as
         reasonably practicable after the Company has received notification of
         the matters to be incorporated in such filing; and

                  (p) in the case of a Shelf Registration, enter into such
         customary agreements and take all such other actions in connection
         therewith (including those reasonably requested by the Holders of a
         majority of the Registrable Securities being sold thereunder) in order
         to expedite or facilitate the disposition of such Registrable
         Securities thereunder including, but not limited to, pursuant to an
         Underwritten Offering and in such connection, (i) to the extent
         possible, make such representations and warranties to the Holders and
         any Underwriters of such Registrable Securities with respect to the
         business of the Company and its subsidiaries, the Registration
         Statement, Prospectus and documents incorporated by reference or deemed
         incorporated by reference, if any, in each case, in form, substance and
         scope as are customarily made by issuers to underwriters in
         underwritten offerings and confirm the same if and when requested, (ii)
         obtain opinions of counsel to the Company (which counsel and opinions,
         in form, scope and substance, shall be reasonably satisfactory to the
         Holders of a majority in principal amount of the Registrable


                                       15


         Securities being sold under such Shelf Registration Statement, such
         Underwriters and their respective counsel) addressed to each selling
         Holder and Underwriter of Registrable Securities, covering the matters
         customarily covered in opinions requested in underwritten offerings,
         (iii) obtain "cold comfort" letters from the independent certified
         public accountants of the Company (and, if necessary, any other
         certified public accountant 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 selling Holder and Underwriter of
         Registrable Securities, 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 (iv) deliver
         such documents and certificates as may be reasonably requested by the
         Holders of a majority in principal amount of the Registrable Securities
         being sold under such Shelf Registration Statement or by the
         Underwriters, and which are customarily delivered in underwritten
         offerings, to evidence the continued validity of the representations
         and warranties of the Company made pursuant to clause (i) above and to
         evidence compliance with any customary conditions contained in an
         underwriting agreement.


                  In the case of a Shelf Registration Statement, the Company may
         require each Holder of Registrable Securities to furnish to the Company
         such information regarding the Holder and the proposed distribution by
         such Holder of such Registrable Securities as the Company may from time
         to time reasonably request in writing. No Holder of Registrable
         Securities may include its Registrable Securities in such Shelf
         Registration Statement unless and until such Holder furnishes such
         information to the Company. Each Holder including Registrable
         Securities in a Shelf Registration Statement shall agree to furnish
         promptly to the Company all information regarding such Holder and the
         proposed distribution by such Holder of such Registrable Securities
         required to make the information previously furnished to the Company by
         such Holder not materially misleading.


                  In connection with an Exchange Offer Registration, each Holder
         exchanging Securities for Exchange Securities shall be required to
         represent that (i) the Exchange Securities are being obtained in the
         ordinary course of business of the Person receiving such Exchange
         Securities, whether or not such Person is a Holder, (ii) neither such
         Holder nor any such other Person has an arrangement or understanding
         with any Person to participate in the distribution of Exchange
         Securities, (iii) other than as set forth in Section 4, if the Holder
         is not a broker-dealer, or is a broker-dealer but will not receive
         Exchange Securities for its own account in exchange for Securities,
         neither the Holder nor any such other Person is engaged in or intends
         to participate in a distribution of the Exchange Securities and (iv)
         neither the Holder nor any such other Person is an "affiliate" of the


                                       16


         Company within the meaning of Rule 405 under the Securities Act or, if
         such Person is an "affiliate", that such Holder will comply with the
         registration and prospectus delivery requirements of the Securities Act
         to the extent applicable.

                  In the case of a Shelf Registration Statement, 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)(v) hereof,
         such Holder will forthwith discontinue disposition of Registrable
         Securities pursuant to a Registration Statement until such Holder's
         receipt of the copies of the supplemented or amended Prospectus
         contemplated by Section 3(i) hereof, and, if so directed by the
         Company, such Holder will destroy or deliver to the Company (at its
         expense) all copies in its possession, other than permanent file copies
         then in such Holder's possession, of the Prospectus covering such
         Registrable Securities current at the time of receipt of such notice.

                  If the Company shall give any such notice to suspend the
         disposition of Registrable Securities pursuant to a Registration
         Statement, the Company shall extend the period during which the
         Registration Statement shall be maintained effective pursuant to this
         Agreement by the number of days during the period from and including
         the date of the giving of such notice to and including the date when
         the Holders shall have received copies of the supplemented or amended
         Prospectus necessary to resume such dispositions. The Company may give
         such notice so long as there are no more than 90 days during any 365
         day period in which such suspensions are in effect.


                  The Holders of Registrable Securities covered by a Shelf
         Registration Statement who desire to do so may sell such Registrable
         Securities in an Underwritten Offering. In any such Underwritten
         Offering, the investment banker or investment bankers and manager or
         managers (the "Underwriters") that will administer the offering will be
         selected by the Majority Holders of the Registrable Securities included
         in such offering, provided that such Underwriters shall be reasonably
         acceptable to the Company.

          4.   Participation of Broker-Dealers in Exchange Offer.

                  (a) The parties hereto understand that the Staff of the SEC
         has taken the position that any broker-dealer that receives Exchange
         Securities for its own account in the Exchange Offer in exchange for
         Securities that were acquired by such broker-dealer as a result of
         market-making or other trading activities (a "Participating
         Broker-Dealer"), may be deemed to be an "underwriter" within the
         meaning of the 1933 Act and must deliver a


                                       17


         prospectus meeting the requirements of the 1933 Act in connection with
         any resale of such Exchange Securities.

                  The Company understands that it is currently the Staff's
         position that if the Prospectus contained in the Exchange Offer
         Registration Statement includes a plan of distribution containing a
         statement to the above effect and the means by which Participating
         Broker-Dealers may resell the Exchange Securities, without naming the
         Participating Broker-Dealers or specifying the amount of Exchange
         Securities owned by them, such Prospectus may be delivered by
         Participating Broker-Dealers to satisfy their prospectus delivery
         obligation under the 1933 Act in connection with resales of Exchange
         Securities for their own accounts, so long as the Prospectus otherwise
         meets the requirements of the 1933 Act.

                  (b) In light of the above, notwithstanding the other
         provisions of this Agreement, the Company agrees that the provisions of
         this Agreement as they relate to a Shelf Registration shall also apply
         to an Exchange Offer Registration to the extent, and with such
         reasonable modifications thereto as may be, reasonably requested by the
         Initial Purchasers or by one or more Participating Broker-Dealers, in
         each case as provided in clause (ii) below, in order to expedite or
         facilitate the disposition of any Exchange Securities by Participating
         Broker-Dealers consistent with the positions of the Staff recited in
         Section 4(a) above; provided that:

                           (i) the Company shall not be required to amend or
                  supplement the Prospectus contained in the Exchange Offer
                  Registration Statement, as would otherwise be contemplated by
                  Section 3(i), for a period exceeding 180 days after the last
                  Exchange Date (as such period may be extended pursuant to the
                  penultimate paragraph of Section 3 of this Agreement) and
                  Participating Broker-Dealers shall not be authorized by the
                  Company to deliver and shall not deliver such Prospectus after
                  such period in connection with the resales contemplated by
                  this Section 4; and

                          (ii) the application of the Shelf Registration
                  procedures set forth in Section 3 of this Agreement to an
                  Exchange Offer Registration, to the extent not required by the
                  positions of the Staff of the SEC or the 1933 Act and the
                  rules and regulations thereunder, will be in conformity with
                  the reasonable request in writing to the Company by the
                  Initial Purchasers or with the reasonable request in writing
                  to the Company by one or more broker-dealers who certify to
                  the Initial Purchasers and the Company in writing that they
                  anticipate that they will be Participating Broker-Dealers; and
                  provided further that, in


                                       18


                  connection with such application of the Shelf Registration
                  procedures set forth in Section 3 to an Exchange Offer
                  Registration, the Company shall be obligated (x) to deal only
                  with one entity representing the Participating Broker-Dealers,
                  which shall be UBS Warburg LLC unless it elects not to act as
                  such representative, (y) to pay the fees and expenses of only
                  one counsel representing the Participating Broker-Dealers,
                  which shall be counsel to the Initial Purchasers unless such
                  counsel elects not to so act and (z) to cause to be delivered
                  only one, if any, "cold comfort" letter with respect to the
                  Prospectus in the form existing on the last Exchange Date and
                  with respect to each subsequent amendment or supplement, if
                  any, effected during the period specified in clause (i) above.

                  (c) The Initial Purchasers shall have no liability to the
         Company, other than as Holders in accordance with the terms hereof, or
         to any other Holder with respect to any request that they may make
         pursuant to Section 4(b) above.

          5.   Indemnification and Contribution.

                 (a) The Company agrees to indemnify and hold harmless the
         Initial Purchasers, each Holder and each Person, if any, who controls
         the Initial Purchasers or any Holder within the meaning of either
         Section 15 of the 1933 Act or Section 20 of the 1934 Act, or is under
         common control with, or is controlled by, the Initial Purchasers or any
         Holder (each, a "Participant"), from and against all losses, claims,
         damages and liabilities (including, without limitation, any legal fees
         or other expenses reasonably incurred by a Participant in connection
         with defending or investigating any such action or claim) caused by any
         untrue statement or alleged untrue statement of a material fact
         contained in any Registration Statement (or any amendment thereto)
         pursuant to which Exchange Securities or Registrable Securities were
         registered under the 1933 Act, including all documents incorporated
         therein by reference, or caused by any omission or alleged omission to
         state therein a material fact required to be stated therein or
         necessary to make the statements therein not misleading, or caused by
         any untrue statement or alleged untrue statement of a material fact
         contained in any Prospectus (as amended or supplemented if the Company
         shall have furnished any amendments or supplements thereto) forming a
         part of such Registration Statement, or caused by any omission or
         alleged omission to state therein a material fact necessary to make the
         statements therein in light of the circumstances under which they were
         made not misleading, except insofar as such losses, claims, damages or
         liabilities are caused by any such untrue statement or omission or
         alleged untrue statement or omission based upon and in conformity with
         information relating to the



                                       19


         Initial Purchasers or any Holder furnished to the Company in writing by
         the Initial Purchasers or any selling Holder expressly for use therein;
         provided that the foregoing indemnity with respect to any Prospectus
         shall not inure to the benefit of any Holder from whom the Person
         asserting any such losses, claims, damages or liabilities purchased
         Securities, or any Person controlling such Holder, if a copy of the
         final Prospectus (as then amended or supplemented if the Company shall
         have furnished any amendments or supplements thereto) was not sent by,
         or delivered on behalf of, such Holder to such Person at or prior to
         the written confirmation of the sale of the Securities to such Person,
         if the final Prospectus (as so amended or supplemented) would have
         cured the defect giving rise to such loss, claim, damage or liability.
         In connection with any Underwritten Offering permitted by Section 3,
         the Company will also enter into an underwriting agreement pursuant to
         which the Company will agree to indemnify the Underwriters, if any,
         selling brokers, dealers and similar securities industry professionals
         participating in such Underwritten Offering, their officers and
         directors and each Person who controls such Persons (within the meaning
         of either Section 15 of the 1933 Act or Section 20 of the 1934 Act) to
         the same extent as provided above with respect to the indemnification
         of the Holders, if requested in connection with any Registration
         Statement for such Underwritten Offering.

                  (b) Each Holder agrees, severally and not jointly, to
         indemnify and hold harmless the Company, the Initial Purchasers and the
         other selling Holders, and each of their respective directors and
         officers who sign the Registration Statement and each Person, if any,
         who controls the Company, the Initial Purchasers and any other selling
         Holder within the meaning of either Section 15 of the 1933 Act or
         Section 20 of the 1934 Act to the same extent as the foregoing
         indemnity from the Company to the Initial Purchasers and the Holders
         pursuant to Section 5(a), but only with reference to information
         relating to such Holder furnished to the Company in writing by such
         Holder expressly for use in any Registration Statement (or any
         amendment thereto) or any Prospectus (or any amendment or supplement
         thereto).

                  (c) In case any proceeding (including any governmental
         investigation) shall be instituted involving any Person in respect of
         which indemnity may be sought pursuant to either paragraph (a) or
         paragraph (b) above, such Person (the "INDEMNIFIED PARTY") shall
         promptly notify the Person against whom such indemnity may be sought
         (the "INDEMNIFYING PARTY") in writing, but the failure to so promptly
         notify the Indemnifying Party shall not negate the obligation to so
         indemnify such Indemnified Party unless the Indemnifying Party is
         materially prejudiced by such delay, and the Indemnifying Party, upon
         request of the Indemnified Party, shall retain counsel reasonably
         satisfactory to the Indemnified Party to represent


                                       20




         the Indemnified Party and any others the Indemnifying Party may
         designate in such proceeding and shall pay the fees and expenses of
         such counsel related to such proceeding. In any such proceeding, any
         Indemnified Party shall have the right to retain its own counsel, but
         the fees and expenses of such counsel shall be at the expense of such
         Indemnified Party unless (i) the Indemnifying Party and the Indemnified
         Party shall have mutually agreed to the retention of such counsel or
         (ii) the named parties to any such proceeding (including any impleaded
         parties) include both the Indemnifying Party and the Indemnified Party
         and, in the opinion of counsel to the Indemnifying Party,
         representation of both parties by the same counsel would be
         inappropriate due to actual or potential differing interests between
         them. It is understood that the Indemnifying Party shall not, in
         connection with any proceeding or related proceedings in the same
         jurisdiction, be liable for (a) the fees and expenses of more than one
         separate firm (in addition to any local counsel) for the Initial
         Purchasers and all Persons, if any, who control the Initial Purchasers
         within the meaning of either Section 15 of the 1933 Act or Section 20
         of the 1934 Act, (b) the fees and expenses of more than one separate
         firm (in addition to any local counsel) for the Company, its directors,
         its officers who sign the Registration Statement and each Person, if
         any, who controls the Company within the meaning of either such Section
         and (c) the fees and expenses of more than one separate firm (in
         addition to any local counsel) for all Holders and all Persons, if any,
         who control any Holders within the meaning of either such Section, and
         that all such fees and expenses shall be reimbursed as they are
         incurred. In such case involving the Initial Purchasers and Persons who
         control the Initial Purchasers, such firm shall be designated in
         writing by the Initial Purchasers. In such case involving the Holders
         and such Persons who control Holders, such firm shall be designated in
         writing by the Majority Holders. In all other cases, such firm shall be
         designated by the Company. The Indemnifying Party shall not be liable
         for any settlement of any proceeding effected without its written
         consent but, if settled with such consent or if there be a final
         judgment for the plaintiff, the Indemnifying Party agrees to indemnify
         the Indemnified Party from and against any loss or liability by reason
         of such settlement or judgment. No Indemnifying Party shall, without
         the prior written consent of the Indemnified Party, effect any
         settlement of any pending or threatened proceeding in respect of which
         such Indemnified Party is or could have been a party and indemnity
         could have been sought hereunder by such Indemnified Party, unless such
         settlement includes an unconditional release of such Indemnified Party
         from all liability on claims that are the subject matter of such
         proceeding.

                  (d) If the indemnification provided for in paragraph (a) or
         paragraph (b) of this Section 5 is unavailable to an Indemnified Party
         or insufficient in respect of any losses, claims, damages or
         liabilities, then each


                                       21



         Indemnifying Party under such paragraph, in lieu of indemnifying such
         Indemnified Party thereunder, shall contribute to the amount paid or
         payable by such Indemnified Party as a result of such losses, claims,
         damages or liabilities in such proportion as is appropriate to reflect
         the relative fault of the Indemnifying Party or parties on the one hand
         and of the Indemnified Party or parties on the other hand in connection
         with the statements or omissions that resulted in such losses, claims,
         damages or liabilities, as well as any other relevant equitable
         considerations. The relative fault of the Company and the Holders shall
         be determined by reference to, among other things, whether the untrue
         or alleged untrue statement of a material fact or the omission or
         alleged omission to state a material fact relates to information
         supplied by the Company or by the Holders and the parties' relative
         intent, knowledge, access to information and opportunity to correct or
         prevent such statement or omission. The Holders' respective obligations
         to contribute pursuant to this Section 5(d) are several in proportion
         to the respective principal amount of Registrable Securities of the
         applicable Holder that were registered pursuant to a Registration
         Statement.

                  (e) The Company and each Holder agree that it would not be
         just or equitable if contribution pursuant to this Section 5(d) were
         determined by pro rata allocation or by any other method of allocation
         that does not take account of the equitable considerations referred to
         in Section 5(d) above. The amount paid or payable by an Indemnified
         Party as a result of the losses, claims, damages and liabilities
         referred to in Section 5(d) above shall be deemed to include, subject
         to the limitations set forth above, any legal or other expenses
         reasonably incurred by such Indemnified Party in connection with
         investigating or defending any such action or claim. Notwithstanding
         the provisions of this Section 5, no Holder shall be required to
         indemnify or contribute any amount in excess of the amount by which the
         total price at which Registrable Securities were sold by such Holder
         exceeds the amount of any damages that such Holder has otherwise been
         required to pay by reason of such untrue or alleged untrue statement or
         omission or alleged omission. No Person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the 1933 Act)
         shall be entitled to contribution from any Person who was not guilty of
         such fraudulent misrepresentation. The remedies provided for in this
         Section 5 are not exclusive and shall not limit any rights or remedies
         which may otherwise be available to any Indemnified Party at law or in
         equity.

                  The indemnity and contribution provisions contained in this
         Section 5 shall remain operative and in full force and effect
         regardless of (i) any termination of this Agreement, (ii) any
         investigation made by or on behalf of the Initial Purchasers, any
         Holder or any Person controlling the Initial Purchasers or any Holder,
         or by or on behalf of the Company, its officers


                                       22




         or directors or any Person controlling the Company, (iii) acceptance of
         any of the Exchange Securities and (iv) any sale of Registrable
         Securities pursuant to a Shelf Registration Statement.

           6.   Miscellaneous.

                  (a) No Inconsistent Agreements. The Company has not entered
         into, and on or after the date of this Agreement will not enter into,
         any agreement which is inconsistent with the rights granted to the
         Holders of Registrable Securities 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.

                  (b) Amendments and Waivers. The provisions of this Agreement,
         including the provisions of this sentence, may not be amended, modified
         or supplemented, and waivers or consents to departures from the
         provisions hereof may not be given unless the Company has obtained the
         written consent of Holders of at least a majority in aggregate
         principal amount of the outstanding Registrable Securities affected by
         such amendment, modification, supplement, waiver or consent; provided,
         however, that no amendment, modification, supplement, waiver or consent
         to any departure from the provisions of Section 5 hereof or this
         paragraph (b) shall be effective as against any Holder of Registrable
         Securities unless consented to in writing by such Holder.

                  (c) Notices. All notices and other communications provided for
         or permitted hereunder shall be made in writing by hand-delivery,
         registered first-class mail, telex, telecopier, or any courier
         guaranteeing overnight delivery (i) if to a Holder, at the most current
         address given by such Holder to the Company by means of a notice given
         in accordance with the provisions of this Section 6(c), which address
         initially is, with respect to the Initial Purchasers, the address set
         forth in the Purchase Agreement; and (ii) if to the Company, initially
         at the Company's address set forth in the Purchase Agreement and
         thereafter at such other address, notice of which is given in
         accordance with the provisions of this Section 6(c).

                  All such notices and communications shall be deemed to have
         been duly given at the time delivered by hand, if personally delivered;
         five Business Days after being deposited in the mail, postage pre-paid,
         if mailed; when answered back, if telexed; when receipt is
         acknowledged, if telecopied; and on the next Business Day if timely
         delivered to an air courier guaranteeing overnight delivery.


                                       23



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

                  (d) Successors and Assigns. This Agreement shall inure to the
         benefit of, and be binding upon, the successors, assigns and
         transferees of each of the parties, including, without limitation and
         without the need for an express assignment, subsequent Holders of
         Registrable Securities; provided that nothing herein shall be deemed to
         permit any assignment, transfer or other disposition of Registrable
         Securities in violation of the terms of the Securities and the Purchase
         Agreement. If any transferee of any Holder shall acquire Registrable
         Securities, in any manner, whether by operation of law or otherwise,
         such Registrable Securities shall be held subject to all of the terms
         of this Agreement, and by taking and holding such Registrable
         Securities such Person shall be conclusively deemed to have agreed to
         be bound by and to perform all of the terms and provisions of this
         Agreement and such Person shall be entitled to receive the benefits
         hereof. The Initial Purchasers shall have no liability or obligation to
         the Company with respect to any failure by a Holder to comply with, or
         any breach by any other Holder of, any of the obligations of such
         Holder under this Agreement.

                  (e) Purchases and Sales of Securities. The Company shall not,
         and shall use its reasonable best efforts to cause its affiliates (as
         defined in Rule 405 under the 1933 Act) not to, purchase and then
         resell or otherwise transfer any Securities.

                  (f) Third Party Beneficiary. Each Holder shall be a third
         party beneficiary to the agreements made hereunder between the Company,
         on the one hand, and the Initial Purchasers, on the other hand, shall
         be bound by all of the terms and provisions of this Agreement and shall
         have the right to enforce such agreements directly to the extent it
         deems such enforcement necessary or advisable to protect its rights or
         the rights of Holders hereunder.

                  (g) Counterparts. This Agreement may be executed in any number
         of counterparts and by the parties hereto in separate counterparts,
         each of which when so executed shall be deemed to be an original and
         all of which taken together shall constitute one and the same
         agreement.

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


                                       24



                  (i) Governing Law This Agreement shall be governed by the laws
         of the State of New York.

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


                                       25



          IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.
