         filed an Exchange Offer Registration Statement covering the offer by

                  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 Securities exchanged.

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

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                  or portions thereof tendered and not validly withdrawn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

                           (ii)     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 principal amount
                  to the principal amount of the Registrable Securities
                  surrendered by such Holder.

         The Company shall use commercially reasonable 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 Purchaser of the names and addresses of the
Holders to whom the Exchange Offer is made, and the Initial Purchaser shall have

                                       5

<PAGE>

the right, subject to applicable law, to contact such Holders and otherwise
facilitate the tender of Registrable Securities in the Exchange Offer.

                  (b)      In the event that (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 by July 6, 2004 or the
         Exchange Offer has been completed and in the opinion of counsel for the
         Initial Purchaser a Registration Statement must be filed and a
         Prospectus must be delivered by the Initial Purchaser in connection
         with any offering or sale of Registrable Securities, the Company shall
         use commercially reasonable efforts to cause to be filed as soon as
         practicable after such determination, date or notice of such opinion of
         counsel is given to the Company, as the case may be, a Shelf
         Registration Statement providing for the sale by the Holders of all of
         the Registrable Securities and to have such Shelf Registration
         Statement declared effective by the SEC. In the event 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 commercially reasonable 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 Shelf Registration Statement (which may be a combined
         Registration Statement with the Exchange Offer Registration Statement)
         with respect to offers and sales of Registrable Securities held by the
         Initial Purchaser after completion of the Exchange Offer. The Company
         agrees to use commercially reasonable 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. 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
         commercially reasonable 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) and Section
         2(b).

                                       6

<PAGE>

         Each Holder shall pay all underwriting discounts and commissions and
         transfer taxes, if any, relating to the sale or disposition of such
         Holder's Registrable Securities pursuant to the 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. In the
         event the Exchange Offer Registration Statement or the Shelf
         Registration Statement is not declared effective on or prior to June 6,
         2004, the interest rate on the Securities will be increased by 0.50%
         per annum until the Exchange Offer Registration Statement or the Shelf
         Registration Statement is declared effective by the SEC. Unless the
         Shelf Registration Statement shall have become effective, in the event
         the Exchange Offer is not consummated on or prior to July 6, 2004, the
         interest rate on the Securities will be increased by 0.50% per annum
         until the Exchange Offer is consummated; provided, however, that on the
         effectiveness of the Shelf Registration Statement, any such increased
         interest will cease to accrue.

                  (e)      Without limiting the remedies available to the
         Initial Purchaser and 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 Initial Purchaser or the Holders for which there is no adequate
         remedy at law, that it will not be possible to measure damages for such
         injuries precisely and that, in the event of any such failure, the
         Initial Purchaser 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:

                  (a)      prepare and file with the SEC a Registration
         Statement on the appropriate form under the 1933 Act, which form (x)
         shall be selected by the Company and (y) shall, in the case of a Shelf
         Registration, be available for the sale of the Registrable Securities
         by the selling Holders thereof and (z) shall comply as to form in all
         material respects with the

                                       7

<PAGE>

         requirements of the applicable form and include all financial
         statements required by the SEC to be filed therewith, and use
         commercially reasonable 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 under the 1933 Act; to 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 Purchaser,
         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
         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 commercially reasonable 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, 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, (iii) subject itself to taxation in any such jurisdiction if
         it is not so subject or (iv) amend its articles of incorporation or
         bylaws;

<PAGE>

                  (e)      in the case of a Shelf Registration, notify each
         Holder of Registrable Securities, counsel for the Holders and counsel
         for the Initial Purchaser 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
         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, of the happening of any event
         during the period a Shelf Registration Statement is effective which
         makes any statement made in such 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 commercially reasonable efforts to obtain the
         withdrawal of any order suspending the effectiveness of a Registration
         Statement at the earliest possible moment and provide prompt 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 exhibits thereto, unless specifically
         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 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 one
         business day prior to the closing of any sale of Registrable
         Securities;

                                       9

                  (i)      in the case of a Shelf Registration, upon the
         occurrence of any event contemplated by Section 3(e)(v) hereof, use
         commercially reasonable 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 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;

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

                  (k)      obtain a CUSIP number for all Exchange Securities or
         Registrable Securities, as the case may be, not later than the
         effective date of a 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, 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 efforts to cause the 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 the Indenture to be so qualified in a timely manner;

                                       10

<PAGE>

                  (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;

                  (n)      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 promptly
         after the Company has received notification of the matters to be
         incorporated in such filing; and

                  (o)      in the case of a Shelf Registration, enter into such
         customary agreements and take all such other actions in connection
         therewith (including those requested by the Holders of a majority of
         the Registrable Securities being sold) in order to expedite or
         facilitate the disposition of such Registrable Securities including,
         but not limited to, an Underwritten Offering and in such connection, 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, and the Prospectus, in each case, in form,
         substance and scope as are customarily made by issuers to underwriters
         in similar underwritten offerings of debt securities 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 and such Underwriters)
         addressed to each selling Holder and Underwriter of Registrable
         Securities, covering the matters customarily covered in opinions
         requested in similar underwritten offerings of debt securities, (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 similar underwritten offerings of debt securities, and (iv)
         deliver such documents and certificates as may be reasonably requested
         by the Holders of a majority in

                                       11

<PAGE>

         principal amount of the Registrable Securities being sold or the
         Underwriters, and which are customarily delivered in similar
         underwritten offerings of debt securities, 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; provided
         that the Company shall not be required to enter into any such agreement
         with respect to any or all of the Registrable Securities more than
         once.

         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 shall be entitled to the
increased interest rate described in Section 2(d) unless and until such Holder
shall have provided all such information which is required by rules of the
Commission to be included in the Shelf Registration Statement prior to the time
it is declared effective. Each selling Holder agrees to promptly furnish
additional information required to be disclosed in order to make the information
previously furnished to the Company by such Holder not misleading.

         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 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.

         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 investment
banker or manager is reasonably satisfactory to the Company.

         The Company may suspend the Shelf Registration Statement (a "SUSPENSION
PERIOD"), if the Company determines, upon advice of counsel, that the continued
effectiveness and use of the Shelf Registration Statement would require the
disclosure of confidential information or interfere with any financing,
acquisition, reorganization or other material transaction involving the Company.
A Suspension Period shall commence on and include the date that the Company
gives notice that the Shelf Registration Statement is no longer effective or the

                                       12

<PAGE>

Prospectus included therein is no longer usable for offers and sales of
Registrable Securities covered by such Registration Statement and continue until
Holders of such Registrable Securities either receive the copies of the
supplemented or amended prospectus or are advised in writing by the Company that
use of the Prospectus may be resumed. Any such suspension may not exceed 60 days
in the aggregate during any twelve month period.

         As a condition to its participation in the Exchange Offer, each Holder
of Registrable Securities (including, without limitation, any Holder who is a
Participating Broker-Dealer) shall furnish, upon the request of the Company,
prior to the consummation of the Exchange Offer, a written representation to the
Company to the effect that (A) that such Holder is not an Affiliate of the
Company or a Participating Broker-Dealer tendering Registrable Securities
acquired directly from the Company for its own account, (B) such Holder will
have no arrangement or understanding with any person to participate in the
distribution of the Registrable Securities or the Exchange Securities within the
meaning of the Act, (C) if the Holder is not a Participating Broker-Dealer or is
a Participating Broker-Dealer but will not receive Exchange Securities for its
own account in exchange for Registrable Securities, neither the Holder nor any
such other Person is engaged in or intends to participate in a distribution of
the Exchange Securities, and (D) any Exchange Securities received by such Holder
will be acquired in the ordinary course of its business. If the Holder is a
Participating Broker-Dealer that will receive Exchange Securities for its own
account in exchange for Registrable Securities, it will represent that the
Registrable Securities to be exchanged for the Exchange Securities were acquired
by it as a result of market-making activities or other trading activities, and
will acknowledge that it will deliver a prospectus meeting the requirements of
the 1933 Act in connection with any resale of such Exchange Securities. It is
understood that, by acknowledging that it will deliver, and by delivering, a
prospectus meeting the requirement of the 1933 Act in connection with any resale
of such Exchange Securities, the Holder is not admitting that it is an
"underwriter" within the meaning of the 1933 Act.

         4.       Participation of Broker-Dealers in Exchange Offer.

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

         The Company understands that it is 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

                                       13

<PAGE>

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 Purchaser 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 the earliest to occur of
                  (1) the date that is 180 days after the last Exchange Date and
                  (2) the date on which all Exchange Securities held by the
                  Participating Broker-Dealers on the Exchange Date have been
                  sold pursuant to the Exchange Offer Registration Statement or
                  are no longer outstanding, 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 to the Company by the Initial Purchaser
                  or with the reasonable request in writing to the Company by
                  one or more broker-dealers who certify to the Initial
                  Purchaser and the Company in writing that they anticipate that
                  they will be Participating Broker-Dealers; and provided
                  further that, in 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 Morgan Stanley & Co.
                  Incorporated unless it elects not to act as such
                  representative, (y) to pay the fees and expenses of only

                                       14

<PAGE>

                  one counsel representing the Participating Broker-Dealers,
                  which shall be counsel to the Initial Purchaser 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 Purchaser shall have no liability to the
         Company or any Holder with respect to any request that it may make
         pursuant to Section 4(b) above.

         5.       Indemnification and Contribution.

                  (a)      The Company agrees to indemnify and hold harmless the
         Initial Purchaser, each Holder and each Person, if any, who controls
         the Initial Purchaser 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 Purchaser or any
         Holder, from and against all losses, claims, damages and liabilities
         (including, without limitation, any out-of-pocket legal or other
         out-of-pocket expenses reasonably incurred by the Initial Purchaser,
         any Holder or any such controlling or affiliated Person 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, 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), or caused
         by any omission or alleged omission to state therein a material fact
         necessary to make the statements therein in the 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 information relating to the Initial Purchaser or any Holder
         furnished to the Company in writing by Morgan Stanley & Co.
         Incorporated or any selling Holder expressly for use therein; provided,
         however, that the foregoing indemnity shall not inure to the benefit of
         any Holder if such Holder sold the Registrable Securities that are the
         subject of the claim (x) after receipt of a notice from the Company
         pursuant to Section 3(e) hereof and prior to receipt of copies of a
         supplemented or amended Registration Statement or Prospectus or (y)
         during a Suspension Period unless notice thereof has not been given. In
         connection with any Underwritten Offering permitted by Section 3, the
         Company will also

                                       15

<PAGE>

         indemnify the Underwriters, if any, selling brokers, dealers and
         similar securities industry professionals participating in the
         distribution, their officers and directors and each Person who controls
         such Persons (within the meaning of the 1933 Act and the 1934 Act) to
         the same extent as provided above with respect to the indemnification
         of the Holders, if requested in connection with the Shelf Registration
         Statement.

                  (b)      Each Holder agrees, severally and not jointly, to
         indemnify and hold harmless the Company, the Initial Purchaser and the
         other selling Holders, and each of their respective directors, officers
         who sign the Registration Statement and each Person, if any, who
         controls the Company, the Initial Purchaser 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 Purchaser and the Holders,
         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 and the indemnifying party, upon
         request of the indemnified party, shall retain counsel reasonably
         satisfactory to the indemnified party to represent the indemnified
         party and any others the indemnifying party may designate in such
         proceeding and shall pay the fees and disbursements 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
         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
         Purchaser and all Persons, if any, who control the Initial Purchaser
         within the meaning of either Section 15 of the 1933 Act or Section 20
         of the 1934 Act, 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

                                       16

         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 Purchaser and Persons who control the Initial Purchaser, such
         firm shall be designated in writing by Morgan Stanley & Co.
         Incorporated. 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. Notwithstanding the foregoing sentence, if at
         any time an indemnified party shall have requested an indemnifying
         party to reimburse the indemnified party for fees and expenses of
         counsel as contemplated by the second and third sentences of this
         paragraph, the indemnifying party agrees that it shall be liable for
         any settlement of any proceeding effected without its written consent
         if (i) such settlement is entered into more than 30 days after receipt
         by such indemnifying party of the aforesaid request and (ii) such
         indemnifying party shall not have reimbursed the indemnified party for
         such fees and expenses of counsel in accordance with such request prior
         to the date of such settlement. 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 referred to therein, then each 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

                                       17

<PAGE>

         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 such
         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 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 paragraph (d) above. The amount paid or payable by an indemnified
         party as a result of the losses, claims, damages and liabilities
         referred to in paragraph (d) above shall be deemed to include, subject
         to the limitations set forth above, any out-of-pocket legal or other
         out-of-pocket 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 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 Purchaser, any Holder or any Person controlling the Initial
Purchaser or any Holder, or by or on behalf of the Company, its officers 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 in any material respect. 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.

                                       18

                  (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 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 Purchaser, 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 prepaid, 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.

         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;
         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 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 Purchaser (in its

                                       19

<PAGE>

         capacity as Initial Purchaser) 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 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 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 Registrable Securities.

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

                  (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.
