            validly tendered will be accepted for exchange;

            period of at least 20 business days or such longer period as may be
            required by the Securities Act from the date such notice is mailed)
            (each such date being an "Exchange Date");

                  (iii) that any Registrable Note not tendered will remain
            outstanding and continues to accrue interest, but will not retain
            any

                                       6
<PAGE>

            rights under this Agreement, other than Notes that represent an
            unsold allotment for the original offering thereof;

                  (iv) that Holders electing to have a Registrable Note
            exchanged pursuant to the Exchange Offer will be required to
            surrender such Registrable Note, together with the enclosed letters
            of transmittal, to the institution and at the address specified in
            the notice prior to the close of business on the last Exchange Date
            (the "Offer Termination Date"); and

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

      As soon as practicable after the Offer Termination Date, the Company
shall:

      (A) accept for exchange in accordance with the Exchange Offer
Registration Statement and the letter of transmittal Registrable Notes or
portions thereof tendered and not validly withdrawn pursuant to the Exchange
Offer or the Private Exchange, as the case may be; and

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

      To the extent not prohibited by any law or the Staff of the SEC, the
Company shall use its reasonable best efforts to complete the Exchange Offer as
provided above and shall comply with the applicable requirements of the
Securities Act, the Exchange Act and other applicable laws and regulations in
connection with the Exchange Offer. The Exchange Offer shall not be subject to
any conditions, other than that (i) the Exchange Offer does not violate
applicable law or any applicable

                                       7
<PAGE>

interpretation of the Staff of the SEC and (ii) the due tendering of
Registrable Notes in accordance with the Exchange Offer. Each Holder of
Registrable Notes who wishes to exchange such Registrable Notes for Exchange
Notes in the Exchange Offer will be required to make certain customary
representations in connection therewith, including representations that such
Holder is not an affiliate of the Company within the meaning of Rule 405 under
the Securities Act, that any Exchange Notes to be received by it will be
acquired in the ordinary course of business and that at the time of the
commencement of the Exchange Offer it has no arrangement with any Person to
participate in the distribution (within the meaning of the Securities Act) of
the Exchange Notes.

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

            (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 Offer Termination
      Date because it would violate applicable law or the applicable
      interpretations of the Staff of the SEC or (ii) in the opinion of counsel
      for the Purchasers a Registration Statement must be filed and a
      Prospectus must be delivered by the Purchasers in connection with any
      offering or sale of Registrable Notes (or Private Exchange Notes) because
      such Registrable Notes (or Private Exchange Notes) represent an unsold
      allotment for the original offering thereof, the Company shall use its
      reasonable best efforts to cause to be filed within 113 days of the
      Closing Date, a Shelf Registration Statement providing for the sale of
      such Registrable Notes (or Private Exchange Notes) and to have such Shelf
      Registration Statement declared effective within 203 days of the Closing
      Date 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 (ii) of the preceding sentence, the Company shall file and have
      declared effective by the SEC both an Exchange Offer Registration
      Statement pursuant to Section 2(a) with respect to all

                                       8
<PAGE>

      Registrable Notes (or Private Exchange Notes) and a Shelf Registration
      Statement with respect to offers and sales of Registrable Notes (or
      Private Exchange Notes) held by the Purchasers after completion of the
      Exchange Offer (or Private Exchange)

      The Company agrees to use its reasonable best efforts to keep the Shelf
      Registration Statement continuously effective until two years from the
      effective date thereof or such shorter period that will terminate when
      all of the Registrable Notes covered by the Shelf Registration Statement
      have been sold pursuant to the Shelf Registration Statement or cease to
      be outstanding. The 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 Securities 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 practicable thereafter. The Company agrees to
      furnish to the Holders of Registrable Notes 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 Notes 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 Notes (or Private
      Exchange Notes) pursuant to a Shelf Registration Statement is interfered
      with by any stop order, injunction or other order or requirement of the
      SEC or any other governmental agency or court, such Registration
      Statement will be deemed not to have become effective during the period
      of such interference until the

                                       9
<PAGE>

      offering of Registrable Notes (or Private Exchange Notes) pursuant to
      such Registration Statement may legally resume.

            (e) The parties hereto agree that the Holders will suffer damages,
      and that it would not be feasible to ascertain the extent of such damages
      with precision if, the Company fails to comply with its obligations under
      Section 2(a) and Section 2(b) hereof (any such failure, a "Registration
      Default"). Therefore, the parties hereto agree that:

            (i) if the Exchange Offer Registration Statement is not filed with
      the SEC within 113 days following the Closing Date (or, if applicable,
      the Shelf Registration Statement is not filed within 120 days of the
      Closing Date), then beginning on the 114th day after the Closing Date,
      additional interest ("Additional Interest") shall accrue on the
      Registrable Notes over and above the accrued interest rate thereon at a
      rate of 0.25% per annum,

            (ii) if the Exchange Offer Registration Statement (or, if
      applicable the Shelf Registration Statement) is filed and is not declared
      effective by the SEC within 203 days following the Closing Date, then
      beginning on the 204th day after the Closing Date, Additional Interest
      shall accrue on the Registrable Notes over and above the accrued interest
      rate thereon at a rate of 0.25% per annum, and

            (iii) if either

            (x) the Company has not exchanged Exchange Notes for all
            Registrable Notes validly tendered in accordance with the terms of
            the Exchange Offer on or prior to 238 days after the Closing Date;

            or

            (y) if applicable, a Shelf Registration Statement is declared
      effective but that Shelf Registration Statement ceases to be effective at
      anytime prior to the expiration of the holding period referred to in Rule
      144(k) promulgated under the Securities Act ("Rule 144(k)"),

      then Additional Interest shall accrue on the Registrable Notes over and
      above accrued interest rate thereon at a rate of 0.25% per annum
      immediately

                                       10
<PAGE>

      following the (a) 239th day after the Closing Date, in the case of (x)
      above, or (b) the day the Shelf Registration Statement ceases to be
      effective, in the case of (y) above.

      However, Additional Interest may in no event exceed 0.25% per annum. Any
Additional Interest will be payable in cash on the same original payment date
of the Notes. In addition, Additional Interest shall (a) cease to accrue upon
the filing of the Exchange Offer Registration Statement (or, if applicable, the
Shelf Registration Statement) (in the case of (i) above), (b) cease to accrue
upon the declaration of effectiveness of the Exchange Offer Registration
Statement (or, if applicable, the declaration and continued effectiveness of
the Shelf Registration Statement) (in the case of (ii) above), and (c) cease to
accrue upon the exchange of Exchange Notes for the Registrable Notes or, if
applicable, upon the effectiveness of the Shelf Registration Statement which
had ceased to remain effective prior to the expiration of the holding period
referred to in Rule 144(k) (in the case of (iii) above).

      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 Notes
      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 Notes for sale in any jurisdiction or the initiation of any

                                       13
<PAGE>

      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 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 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 Notes, 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 Notes to facilitate the timely preparation and
      delivery of certificates representing Registrable Notes to be sold and
      not bearing any restrictive legends (unless required by applicable
      securities laws) and enable such Registrable Notes 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
      Notes;

            (i) in the case of a Shelf Registration, upon the occurrence of any
      event contemplated by Section 3(e)(v) hereof, use its best efforts to
      prepare a supplement or post-effective amendment to a Registration
      Statement or the related Prospectus or any document incorporated therein
      by reference or file any other required document so that, as thereafter
      delivered to the purchasers of the Registrable Notes, such Prospectus
      will not contain any untrue statement of a material fact or omit to state
      a material fact necessary to make the statements therein, in the light of
      the circumstances under which they were made, not misleading. The Company
      agrees to notify the Holders to suspend use of the Prospectus as promptly
      as practicable after the occurrence

                                       14
<PAGE>

      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
      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 counsel for the Holders and make such of the
      representatives of the Company as shall be reasonably requested by
      counsel for 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 or any document which is to be
      incorporated by reference into a Registration Statement or a Prospectus,
      of which counsel for the Holders shall not have, (i) with respect to an
      Exchange Offer Registration Statement, simultaneously upon filing with
      the SEC, been advised and furnished a copy or (ii) with respect to a
      Shelf Registration Statement, previously been advised and furnished a
      copy or to which counsel for the Holders shall reasonably object
      (provided, however that this section 3(j) shall not prevent the Company
      from complying with its ongoing reporting obligations under applicable
      securities laws);

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

            (l) cause the Indenture to be qualified under the Trust Indenture
      Act of 1939, as amended (the "TIA")(unless an exemption under Rule 4d-9
      under the TIA is available), to the extent not already so qualified, in
      connection with the registration of the Exchange Notes or Registrable
      Notes, 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 its

                                       15
<PAGE>

      best 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;

            (m) in the case of a Shelf Registration, make available for
      inspection by a representative of the Holders of the Registrable Notes,
      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 relevant
      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; provided, however, that each such party shall be required to
      maintain confidences and not to disclose to any other person any
      information or records reasonably designated by the Company as being
      confidential;

            (n) if reasonably requested by any Holder of Registrable Notes
      covered by the Shelf 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;

            (o) cause all Registrable Notes covered by a Registration Statement
      to be rated with the appropriate rating agencies, (i) if the Notes have
      been rated prior to the initial resale by the Purchasers or (ii) if the
      Notes have not been previously rated, if so requested by the Majority
      Holders; and

            (p) in the case of an Underwritten Offering pursuant to a Shelf
      Registration, enter into such customary agreements and take all such
      other customary actions in connection therewith (including, those
      reasonably requested by counsel for the Holders) in order to expedite or
      facilitate the disposition of such Registrable Notes and in such
      connection, (i) to the extent

                                       16
<PAGE>

      possible, make such representations and warranties to the Holders and any
      Underwriters of such Registrable Notes 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 Companies 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 and such
      Underwriters and their respective counsel) addressed to each selling
      Holder and Underwriter of Registrable Notes, covering the matters
      customarily covered in opinions requested in underwritten offerings,
      (iii) obtain 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 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 Notes, such letters to be
      in customary form and covering matters of the type customarily covered in
      comfort letters in connection with primary underwritten offerings,
      subject to receipt of appropriate documentation as contemplated, and only
      if permitted, by the Statement of Auditing Standards No. 72 comfort, and
      (iv) deliver such documents and certificates as may be reasonably
      requested by counsel for the Holders 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
      in an underwriting agreement. In the case of any Underwritten Offering,
      the Company shall provide written notice to the Holders of all
      Registrable Notes of such Underwritten Offering at least 30 days prior to
      the filing of a prospectus supplement for such Underwritten Offering.
      Such notice shall (x) offer each such Holder the right to participate in
      such Underwritten Offering, (y) specify a date, which shall be no earlier
      than 10 days following the date of such notice, by which such Holder must
      inform the Company of its intent to participate in such Underwritten
      Offering and (z) include the instructions such Holder must follow in
      order to participate in such Underwritten Offering.

      In the case of a Shelf Registration Statement, the Company may require
each Holder of Registrable Notes to promptly furnish, but not later than 15
days after written request, to the Company such information regarding the
Holder and the

                                       17
<PAGE>

proposed distribution by such Holder of such Registration Notes as the Company
may from time to time reasonably request in writing. Notwithstanding anything
in this Agreement to the contrary, if a Holder does not provide the information
required above, then such Holder will not be included in such Shelf
Registration Statement.

      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 Notes pursuant to a Registration
Statement until such Holder's receipt of the copies of the supplemented or
amended Prospectus contemplated by Section 3(i) hereof, 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 Registration Notes current
at the time of receipt of such notice.

      If the Company shall give any such notice to suspend the disposition of
Registrable Notes 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 Holders of Registrable Notes covered by a Shelf Registration
Statement who desire to do so may sell such Registrable Notes 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 Holders of a majority in
principal amount of the Registrable Notes included in such offering; such
selection must be approved by the Company which approval shall not be
unreasonably withheld or delayed.

      4.    Participation of Broker-Dealers in Exchange Offer.

            (a) The Company understands that the Staff of the SEC has taken the
      position that any broker-dealer that receives Exchange Notes for its own
      account in the Exchange Offer in exchange for Notes 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"

                                       18
<PAGE>

      within the meaning of the Securities Act in connection with any resale of
      such Exchange Notes.

            (b) 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 which Participating Broker-Dealers may resell the
      Exchange Notes, without naming the Participating Broker-Dealers or
      specifying the amount of Exchange Notes owned by them, such Prospectus
      may be delivered by Participating Broker-Dealers to satisfy their
      prospectus delivery obligation under the Securities Act in connection
      with resales of Exchange Notes for their own accounts, so long as the
      Prospectus otherwise meets the requirements of the Securities Act.

            (c) 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 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 Notes 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 two years after the Offer Termination Date (as
            such period may be extended pursuant to the penultimate paragraph
            of Section 3) 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 Securities Act and the rules and
            regulations

                                       19
<PAGE>

            thereunder, will be in conformity with the reasonable request in
            writing to the Company by one or more broker-dealers who certify to
            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 Deutsche Bank Securities Inc. ("Deutsche Bank") if
            Deutsche Bank so requests or otherwise the Participating
            Broker-Dealer holding the largest aggregate principal amount of
            Notes, (y) to pay the fees and expenses of only one counsel
            representing the Participating Broker-Dealers and (z) to cause to
            be delivered only one, if any, comfort letter with respect to the
            Prospectus in the form existing on the Offer Termination Date.

      5.    Indemnification and Contribution.

      (a) The Company agrees to indemnify and hold harmless each Holder of the
Notes, any Participating Broker-Dealer and each person, if any, who controls
such Holder or such Participating Broker-Dealer within the meaning of the
Securities Act or the Exchange Act (each Holder, any Participating
Broker-Dealer, and such controlling persons are referred to collectively as the
"Indemnified Parties") from and against any losses, claims, damages or
liabilities, joint or several, or any actions in respect thereof (including,
but not limited to, any losses, claims, damages, liabilities or actions
relating to purchases and sales of the Notes) to which each Indemnified Party
may become subject under the Securities Act, the Exchange Act or otherwise,
insofar as such losses, claims, damages, liabilities or actions arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in a Registration Statement or Prospectus or in any amendment or
supplement thereto, or arise out of, or are based upon, the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse,
as incurred, the Indemnified Parties for any legal or other expenses reasonably
incurred by the Indemnified Parties for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action in respect thereof; provided, however, that
(i) the Company shall not be liable

                                       20
<PAGE>

in any such case to the extent that such loss, claim, damage or liability
arises out of or is based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in a Registration Statement or Prospectus
or in any amendment or supplement thereto or in any preliminary prospectus
relating to a Shelf Registration in reliance upon and in conformity with
written information pertaining to such Indemnified Party and furnished to the
Company by or on behalf of such Holder and furnished to the Company by or on
behalf of such Holder specifically for inclusion therein and (ii) with respect
to any untrue statement or omission or alleged untrue statement or omission
made in any preliminary prospectus relating to a Shelf Registration Statement,
the indemnity agreement contained in this subsection (a) shall not inure to the
benefit of any Holder or Participating Broker-Dealer from whom the person
asserting any such losses, claims, damages or liabilities purchased the Notes
concerned, to the extent that a prospectus relating to such Notes was required
to be delivered by such Holder or Participating Broker-Dealer under the
Securities Act in connection with such purchase or distribution and any such
loss, claim, damage or liability of such Holder or Participating Broker-Dealer
results from the fact that there was not sent or given to such person, at or
prior to the written confirmation of the sale of such Notes to such person, a
copy of the final prospectus if the Company had previously furnished copies
thereof to such Holder or Participating Broker-Dealer; provided, further,
however, that this indemnity agreement will be in addition to any liability
which the Company may otherwise have to such Indemnified Party. The Company
shall also indemnify underwriters, their partners, officers and directors and
each person who controls such underwriters within the meaning of the Securities
Act or the Exchange Act to the same extent as provided above with respect to
the indemnification of the Holders of the Notes if requested by such Holders.

      (b) Each Holder of the Notes severally and not jointly, will indemnify
and hold harmless the Company and each person, if any, who controls the Company
within the meaning of the Securities Act or the Exchange Act from and against
any losses, claims, damages or liabilities or any actions in respect thereof,
to which the Company or any such controlling person may become subject under
the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or Prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the

                                       21
<PAGE>

statements therein not misleading, but in each case only to the extent that the
untrue statement or omission or alleged untrue statement or omission was made
in reliance upon and in conformity with written information pertaining to such
Holder and furnished to the Company by or on behalf of such Holder or Purchaser
specifically for inclusion therein; and, subject to the limitation set forth
immediately preceding this clause, shall reimburse, as incurred, the Company
for any legal or other expenses reasonably incurred by the Company or any such
controlling person in connection with investigating or defending any loss,
claim, damage, liability or action in respect thereof. This indemnity agreement
will be in addition to any liability which such Holder or Purchaser may
otherwise have to the Company or any of its controlling persons.

      Promptly after receipt by an Indemnified Party under this Section of
notice of the commencement of any action, such Indemnified Party will, if a
claim in respect thereof is to be made against the Indemnifying Party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any Indemnified Party otherwise than
under subsection (a) or (b) above, except to the extent that the failure to so
notify has materially prejudiced the rights of the indemnifying party under
this Agreement. If any such proceeding shall be brought or asserted against an
Indemnified Party and it shall have notified the indemnifying party thereof,
the indemnifying party shall retain counsel reasonably satisfactory to the
Indemnified Party to represent the Indemnified Party and any others entitled to
indemnification pursuant to this Section 5 that the indemnifying party may
designate in such proceeding and shall pay the fees and expenses of such
counsel related to such proceeding, as incurred. 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 contrary; (ii) the indemnifying party has failed within a
reasonable time to retain counsel reasonably satisfactory to the Indemnified
Party; (iii) the Indemnified Party shall have reasonably concluded that there
may be legal defenses available to it that are different from or in addition to
those available to the indemnifying party; or (iv) the named parties in 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 and agreed that the indemnifying party shall
not, in connection with any proceeding or related proceeding in the same

                                       22
<PAGE>

jurisdiction, be liable for the fees and expenses of more than one separate
firm (in addition to any local counsel) for all Indemnified Parties, and that
all such fees and expenses shall be reimbursed as they are incurred. Any such
separate firm (x) for any Purchaser, its affiliates and any control Persons of
such Purchaser shall be designated in writing by Deutsche Bank, (y) for any
Holder, its affiliates and any control Persons of such Holder shall be
designated in writing by the Majority Holders and (z) in all other cases shall
be designated in writing by the Company. No indemnifying party shall, without
the prior written consent of the Indemnified Party, which consent shall not be
unreasonably withheld, effect any settlement of any pending or threatened
action in respect of which any Indemnified Party is or could have been a party
and indemnity could have been sought hereunder by such Indemnified Party unless
such settlement includes an unconditional release of such Indemnified Party, in
form and substance reasonably satisfactory to such indemnified person, from all
liability on any claims that are the subject matter of such action and does not
include a statement as to or an admission of fault, culpability or failure to
act by or on behalf of any Indemnified Party.

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

                                       23
<PAGE>

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

The agreements contained in this Section 5 shall survive the exchange of the
Notes pursuant to a Registration Statement and shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement or any
investigation made by or on behalf of any Indemnified Party.

      6.    Miscellaneous.
