applicable interpretation of the Staff of the SEC, the Issuers shall use their
best efforts to cause to be filed an Exchange Offer Registration Statement
covering the offer by the Issuers to the Holders to exchange all of the
Registrable Securities for Exchange Securities and to have such Registration
Statement remain effective until the closing of the Exchange Offer. The Issuers
shall commence the Exchange Offer promptly after the Exchange Offer Registration
Statement has been declared effective by the SEC and use their best efforts to
have the Exchange Offer consummated not later than 60 days after such effective
date.

               The Issuers shall commence the Exchange Offer by mailing the
related exchange offer Prospectus and accompanying documents to each Holder
stating, in addition to such other disclosures as are required by applicable
law:

               (i)   that the Exchange Offer is being made pursuant to this
          Registration Rights Agreement and that all Registrable Securities
          validly tendered will be accepted for exchange;

                                       4

<PAGE>

               (ii)  the dates of acceptance of election of exchange (which
          shall be a period of at least 30 business days from the date such
          notice is mailed) (the "Exchange Dates");

               (iii) that any Registrable Security not tendered will remain
          outstanding and continue to accrue interest, but will not retain any
          rights under this Registration Rights Agreement;

               (iv)  that Holders electing to have a Registrable Security
          exchanged pursuant to the Exchange Offer will be required to surrender
          such Registrable Security, together with the enclosed letters of
          transmittal, to the institution and at the address (located in the
          Borough of Manhattan, The City of New York) specified in the notice
          prior to the close of business on the last Exchange Date; and

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

               As soon as practicable after the last Exchange Date, the Issuers
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 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 Issuers shall use their best efforts to complete the Exchange Offer as
provided above and shall comply with the applicable requirements of the 1933
Act, the 1934 Act and other applicable laws and regulations in connection with
the Exchange Offer. The Exchange Offer shall not be subject to any material
conditions, other than that the Exchange Offer does not violate applicable law
or any applicable interpretation of the Staff of the SEC. The Issuers shall
inform the Placement Agents of the names and addresses of the Holders to whom
the Exchange Offer is made, and the Placement Agents shall have 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 Issuers determine 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
210th day after the Issue Date or (iii) the Exchange Offer has been completed
and in the opinion of counsel for the Placement Agents a Registration Statement
must be filed and a Prospectus must be delivered by the Placement Agents in
connection with any offering or sale of Registrable Securities, the Issuers
shall use their best efforts to cause to be

                                       5

<PAGE>

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 Issuers are required to file a Shelf
Registration Statement solely as a result of the matters referred to in clause
(iii) of the preceding sentence, the Issuers shall use their best efforts to
file and have declared effective by the SEC both an Exchange Offer Registration
Statement pursuant to Section 2(a) with respect to all Registrable Securities
and a 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 Placement Agents after
completion of the Exchange Offer. The Issuers agree to use their best efforts to
keep the Shelf Registration Statement continuously effective until the
expiration of the period referred to in Rule 144(k) with respect to the
Registrable Securities or such shorter period that will terminate when all of
the Registrable Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement. The Issuers further agree to
supplement or amend the Shelf Registration Statement if required by the rules,
regulations or instructions applicable to the registration form used by the
Issuers 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 their best efforts to cause any such amendment to become effective and
such Shelf Registration Statement to become usable as soon as thereafter
practicable. The Issuers agree 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 Issuers 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 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. As provided for in
the Indenture, in the event the Exchange Offer is not consummated and the Shelf
Registration Statement is not declared effective as set forth below, then, the
interest rate on the Securities will be increased (the "Additional Interest") as
follows:

               (i)   if (A) neither the Exchange Offer Registration Statement
          nor a Shelf Registration Statement has been filed with the SEC on or
          prior to the 90th day after the Issue Date or (B) the Issuers are
          required to file a Shelf Registration Statement pursuant to Section
          2(b)(iii) hereof and such Shelf Registration Statement is not filed on
          or prior to the Filing Date applicable thereto then, commencing on the
          day after either such 90th day in the case of clause (A) or such
          Filing Date in the case of clause (B), Additional Interest shall
          accrue on the principal amount of the Registrable Securities at a rate
          of 0.25% per

                                       6

<PAGE>

          annum for the first 90 days immediately following thereafter, and such
          Additional Interest rate shall increase by an additional 0.25% per
          annum at the beginning of each subsequent 90-day period; or

               (ii)  if (A) neither the Exchange Offer Registration Statement
          nor a Shelf Registration Statement is declared effective by the SEC on
          or prior to the 180th day after the Issue Date or (B) the Issuers are
          required to file a Shelf Registration Statement pursuant to Section
          2(b)(iii) hereof and such Shelf Registration Statement is not declared
          effective by the SEC on or prior to the 90th day following the Filing
          Date applicable thereto then, commencing on the day after either such
          180th day in the case of clause (A) or Filing Date in the case of
          clause (B), Additional Interest shall accrue on the principal amount
          of the Registrable Securities at a rate of 0.25% per annum for the
          first 90 days immediately following thereafter, and such Additional
          Interest rate shall increase by an additional 0.25% per annum at the
          beginning of each subsequent 90-day period; or

               (iii) subject to Sections 2(f) and 2(g) if (A) the Issuers have
          not exchanged Exchange Securities for all Securities validly tendered
          in accordance with the terms of the Exchange Offer on or prior to the
          210th day after the Issue Date or (B) if applicable, the Shelf
          Registration Statement has been declared effective and such Shelf
          Registration Statement ceases to be effective at any time prior to the
          second anniversary of the Closing Date (or, if earlier, the date when
          all Securities have been disposed of thereunder), then Additional
          Interest shall accrue on the principal amount of the Registrable
          Securities at a rate of .25% per annum for the first 90 days
          commencing on (x) the 211th day after the Closing Date, in the case of
          (A) above, or (y) the day such Shelf Registration Statement ceases to
          be effective in the case of (B) above, and such Additional Interest
          rate shall increase by an additional .25% per annum at the beginning
          of each subsequent 90-day period;

provided, however, that the Additional Interest rate on the Securities may not
exceed in the aggregate 1.0% per annum; provided further, that the Issuers shall
in no event be required to pay additional interest for more than one event in
clauses (i), (ii), or (iii) at any one time; provided further, however, that (1)
upon the filing of the Exchange Offer Registration Statement or a Shelf
Registration Statement (in the case of clause (a) above), (2) upon the
effectiveness of the Exchange Offer Registration or a Shelf Registration
Statement (in the case of clause (b) above), or (3) upon the exchange of
Exchange Securities for all Securities tendered (in the case of clause (c)(A)
above), or upon the effectiveness of the Shelf Registration Statement which had
ceased to remain effective (in the case of clause (c)(B) above), Additional
Interest on the Securities as a result of such clause (or the relevant subclause
thereof), as the case may be, shall cease to accrue.

               (e) Without limiting the remedies available to the Placement
Agents and the Holders, the Issuers acknowledge that any failure by the Issuers
to comply with their obligations under Section 2(a) and Section 2(b) hereof may
result in material irreparable injury to the Placement Agents 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 Placement Agents or any Holder may obtain such relief as may be
required to specifically enforce any Issuer's obligations under Section 2(a) and
Section 2(b) hereof.

          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

          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 Issuers consent to the use of such Prospectus and any
          amendment or supplement thereto in accordance with applicable law by

          Prospectus or any amendment or supplement thereto in accordance with
          applicable law;

               (d) use their best efforts to register or qualify the Registrable
          Securities under all applicable state securities or "blue sky" laws of
          such jurisdictions as any Holder of Registrable Securities covered by

          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

          shall not be required to (i) qualify as a foreign corporation or as a
          dealer in securities in any jurisdiction where it would not otherwise
          be required to qualify but for this Section 3(d), (ii) file any
          general

          consent to service of process or (iii) subject itself to taxation in
          any such jurisdiction if it is not so subject;

               (e) in the case of a Shelf Registration, notify each Holder of
          Registrable Securities, counsel for the Holders and counsel for the
          Placement Agents 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 Issuers
          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 Issuers receive
          any notification with respect to the suspension of the qualification
          of the Registrable Securities for sale in any jurisdiction or the
          initiation of any proceeding for such purpose, (v) of the happening of
          any event during the period a Shelf Registration Statement is
          effective which makes any statement made in such 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 Issuers that a
          post-effective amendment to a Registration Statement would be
          appropriate;

               (f) make every reasonable effort to obtain the withdrawal of any

          earliest possible moment and provide immediate notice to each Holder
          of the withdrawal of any such order;

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

               (h) in the case of a Shelf Registration, cooperate with the
          selling Holders of Registrable Securities to facilitate the timely
          preparation and delivery of certificates representing Registrable
          Securities to be sold and not bearing any restrictive legends 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;

               (i) in the case of a Shelf Registration, upon the occurrence of
          any event contemplated by Section 3(e)(v) hereof, use their best
          efforts to prepare and file with the SEC a supplement or
          post-effective amendment to a Registration Statement or the related
          Prospectus or any document incorporated therein by reference or file
          any other required

                                       9

<PAGE>

          document so that, as thereafter delivered to the purchasers of the
          Registrable Securities, such Prospectus will not contain any untrue
          statement of a material fact or omit to state a material fact
          necessary to make the statements therein, in light of the
          circumstances under which they were made, not misleading. The Issuers
          agree 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
          Issuers have 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 a
          Prospectus after initial filing of a Registration Statement, provide
          copies of such document to the Placement Agents and their counsel
          (and, in the case of a Shelf Registration Statement, the Holders and
          their counsel) and make such of the representatives of the Issuers as
          shall be reasonably requested by the Placement Agents or their counsel
          (and, in the case of a Shelf Registration Statement, the Holders or
          their counsel) available for discussion of such document, and shall
          not at any time file or make any amendment to the 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 the Placement Agents and their counsel (and, in
          the case of a Shelf Registration Statement, the Holders and their
          counsel) shall not have previously been advised and furnished a copy
          or to which the Placement Agents or their counsel (and, in the case of
          a Shelf Registration Statement, the Holders or their counsel) shall
          reasonably object within 5 days after receipt thereof;

               (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 its 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
          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 Issuers and subsidiaries of the Issuers, and cause
          the respective officers, directors and employees of the Issuers and
          any of their subsidiaries to supply all information reasonably
          requested by any such representative, Underwriter, attorney or
          accountant in connection with a Shelf

                                       10

<PAGE>

          Registration Statement; provided that any such representative,
          Underwriter or other recipient shall agree in writing that any
          information designated as confidential by the Company shall be kept
          confidential by such recipient except to the extent reasonably
          necessary in connection with an offering.

               (n) in the case of a Shelf Registration, use their commercially
          reasonable efforts to cause all Registrable Securities to be listed on
          any securities exchange or any automated quotation system on which
          similar securities issued by the Issuer are then listed if requested
          by the Majority Holders, to the extent such Registrable Securities
          satisfy applicable listing requirements;

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

               (p) in the case of a Shelf Registration, enter into such
          customary agreements and take all such other actions in connection
          therewith (including those 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,
          (i) to the extent possible, make such representations and warranties
          to the Holders and any Underwriters of such Registrable Securities
          with respect to the business of the Issuers and their subsidiaries,
          the Registration Statement, Prospectus and documents incorporated by
          reference or deemed incorporated by reference, if any, in each case,
          in form, substance and scope as are customarily made by Issuers to
          underwriters in underwritten offerings and confirm the same if and
          when requested, (ii) obtain opinions of counsel to the Issuers (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 Securities, covering the matters customarily covered in
          opinions requested in underwritten offerings, (iii) obtain "cold
          comfort" letters from the independent certified public accountants of
          the Issuers (and, if necessary, any other certified public accountant
          of any subsidiary of the Issuers, or of any business acquired by the
          Issuers for which financial statements and financial data are or are
          required to be included in the Registration Statement) addressed to
          each selling Holder and Underwriter of Registrable Securities, such
          letters to be in customary form and covering matters of the type
          customarily covered in "cold comfort" letters in connection with
          underwritten offerings, and (iv) deliver such documents and
          certificates as may be reasonably requested by the Holders of a
          majority in principal amount of the Registrable Securities being sold
          or the Underwriters, and which are customarily delivered in
          underwritten offerings, to evidence the continued validity of the
          representations and warranties of the Issuers made pursuant to clause
          (i) above and to evidence compliance with any customary conditions
          contained in an underwriting agreement.

                                       11

               In the case of a Shelf Registration Statement, the Issuers may
require each Holder of Registrable Securities to furnish to the Issuers such
information regarding the Holder and the proposed distribution by such Holder of
such Registrable Securities as the Issuers may from time to time reasonably
request in writing.

               In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Issuers of the happening of any event
of the kind described in Section 3(c)(iii) or 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 Issuers, such Holder will deliver to the Issuers (at its
expense) all copies in its possession, other than permanent file copies then in
such Holder's possession, of the Prospectus covering such Registrable Securities
current at the time of receipt of such notice. If the Issuers shall give any
such notice to suspend the disposition of Registrable Securities pursuant to a
Registration Statement, the Issuers 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 Issuers may give any such notice only twice during any
365 day period and any such suspensions may not exceed 45 days for each
suspension and there may not be more than two suspensions in effect during any
365 day period.

               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.

               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 Issuers understand 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 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.

                                       12

<PAGE>

               (b) In light of the above, notwithstanding the other provisions
of this Agreement, the Issuers agree 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 Placement Agents 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 Issuers shall not be required to amend or supplement
          the Prospectus contained in the Exchange Offer Registration Statement,
          as would otherwise be contemplated by Section 3(i), for a period
          exceeding 180 days after the last Exchange Date (as such period may be
          extended pursuant to the penultimate paragraph of Section 3 of this
          Agreement) and Participating Broker-Dealers shall not be authorized by
          the Issuers 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 Issuers by
          the Placement Agents or with the reasonable request in writing to the
          Issuers by one or more broker-dealers who certify to the Placement
          Agents and the Issuers 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 one counsel representing the
          Participating Broker-Dealers, which shall be counsel to the Placement
          Agents 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 Placement Agents shall have no liability to the Issuers
or any Holder with respect to any request that it may make pursuant to Section
4(b) above.

               5. Indemnification and Contribution.

               (a) Each of the Issuers, jointly and severally, agrees to
indemnify and hold harmless the Placement Agents, each Holder and each Person,
if any, who controls any Placement Agent 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, any Placement Agent or any Holder,
from and against all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred by the Placement
Agent, 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,
including all documents incorporated therein by reference, or caused by any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
caused by any untrue statement or alleged untrue statement of a

                                       13

<PAGE>

material fact contained in any Prospectus (as amended or supplemented if the
Issuers 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 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 Placement
Agents or any Holder furnished to the Issuers in writing through Morgan Stanley
& Co. Incorporated or any selling Holder expressly for use therein. In
connection with any Underwritten Offering permitted by Section 3, the Issuers
will also 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 any Registration Statement.

               (b) Each Holder agrees, severally and not jointly, to indemnify
and hold harmless the Issuers, the Placement Agents 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 Issuers, any
Placement Agent 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 Issuers to the Placement Agents and the
Holders, but only with reference to information relating to such Holder
furnished to the Issuers 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 Placement Agents and all
Persons, if any, who control any Placement Agent within the meaning of either
Section 15 of the 1933 Act or

                                       14

<PAGE>

Section 20 of the 1934 Act, (b) the fees and expenses of more than one separate
firm (in addition to any local counsel) for the Company, their directors, their
officers who sign the Registration Statement and each Person, if any, who
controls the Company within the meaning of either such Section and (c) the fees
and expenses of more than one separate firm (in addition to any local counsel)
for all Holders and all Persons, if any, who control any Holders within the
meaning of either such Section, and that all such fees and expenses shall be
reimbursed as they are incurred. In such case involving the Placement Agents and
Persons who control the Placement Agents, 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, 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
Issuers 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 Issuers 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 Issuers 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

                                       15

<PAGE>

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 legal or other expenses reasonably incurred by such indemnified party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 5, no Holder shall be required to
indemnify or contribute any amount in excess of the amount by which the total
price at which Registrable Securities were sold by such Holder exceeds the
amount of any damages that such Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation. The remedies
provided for in this Section 5 are not exclusive and shall not limit any rights
or remedies which may otherwise be available to any indemnified party at law or
in equity.

               The indemnity and contribution provisions contained in this
Section 5 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of the Placement Agents, any Holder or any Person controlling any Placement
Agent or any Holder, or by or on behalf of the Company, their officers or
directors or any Person controlling the Issuers, (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. None of the Issuers has entered
into, and on or after the date of this Agreement will not enter into, any
agreement which is inconsistent with the rights granted to the Holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof. The rights granted to the Holders hereunder do not in any way
conflict with and are not inconsistent with the rights granted to the holders of
the Issuers' other issued and outstanding securities under any such agreements.

               (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Issuers have 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 Issuers by means of a notice given in accordance with the provisions of this
Section 6(c), which address initially is, with respect to the Placement Agents,
the address set forth in the Placement Agreement; and (ii) if to the Issuers,
initially at the Company's addresses set forth in the Placement Agreement and
thereafter at such other address, notice of which is given in accordance with
the provisions of this Section 6(c).

                                       16

<PAGE>

               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 Placement 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
Placement Agents (in their capacity as Placement Agents) shall have no liability
or obligation to the Issuers 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. Until the earlier of (1)
two years after the Closing Date and (2) the consummation of the Exchange Offer,
the Issuers shall not, and shall use their best efforts to cause its affiliates
(as defined in Rule 405 under the 1933 Act) not to, purchase and then resell or
otherwise transfer any Securities, unless such Securities are held in the form
of a non-global note.

               (f) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Issuers, on the one
hand, and the Placement Agents, 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.
