         (a) To the extent not prohibited by any applicable law or applicable
interpretation of the Staff of the SEC, the Company shall prepare and cause to
be filed with the SEC an Exchange Offer Registration Statement covering the
offer by the Company to the Holders to exchange all of the Registrable
Securities for Exchange Securities and shall use its reasonable best efforts to
cause such Registration Statement to be declared effective under the 1933 Act by
the SEC and to cause such Registration Statement to remain effective until the
closing of the Exchange Offer. The Company shall commence the Exchange Offer
promptly after the Exchange Offer Registration Statement has been declared
effective by the SEC and shall have the Exchange Offer consummated not later
than 140 days following the date of the original issuance of the Securities. The
Company 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;

                  (ii) the dates of acceptance for exchange (which shall be a
         period of at least 20 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

                                        4
<PAGE>

                  (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 (but in
         any event no later than 140 days following the date of the original
         issuance of the Securities) the Company shall:

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         thereof tendered and not validly withdrawn pursuant to the Exchange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

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

         The Company shall comply with the applicable requirements of the 1933
Act, the 1934 Act and other applicable laws and regulations in connection with
the Exchange Offer. The Exchange Offer shall not be subject to any conditions,
other than that the Exchange Offer does not violate applicable law or any
applicable interpretation of the Staff of the SEC. The Company shall inform the
Initial Purchasers of the names and addresses of the Holders to whom the
Exchange Offer is made, and the Initial Purchasers shall have the right, subject
to applicable law, to contact such Holders and otherwise facilitate the tender
of Registrable Securities in the Exchange Offer.

         (b) In the event that (i) the Company determines that the Exchange
Offer Registration provided for in Section 2(a) above is not available or may
not be consummated as soon as practicable after the last Exchange Date because
it would violate applicable law or the applicable interpretations of the Staff
of the SEC, or (ii) the Exchange Offer has been completed and in the opinion of
counsel for the Initial Purchasers a Registration Statement must be filed and a
Prospectus must be delivered by the Initial Purchasers in connection with any
offering or sale of Registrable Securities constituting any portion of an unsold
allotment, the Company shall cause to be filed as soon as practicable after such
determination 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 use its reasonable best
efforts to have such Shelf Registration Statement declared effective by the SEC.
In the event the Company is required to file a Shelf Registration Statement
solely as a result of the matters referred to in clause (ii) of the preceding
sentence, the Company shall file and use its reasonable best efforts to 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

                                        5
<PAGE>

the Initial Purchasers after completion of the Exchange Offer. The Company
agrees to use its reasonable best efforts to keep the Shelf Registration
Statement continuously effective until the expiration of the period referred to
in Rule 144(k) with respect to the Registrable Securities or such shorter period
that will terminate when all of the Registrable Securities covered by the Shelf
Registration Statement have been sold pursuant to the Shelf Registration
Statement. The Company further agrees to supplement or amend the Shelf
Registration Statement if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the 1933 Act or by any other rules and regulations
thereunder for shelf registration or if reasonably requested by a Holder with
respect to information relating to such Holder, and to use its reasonable best
efforts to cause any such amendment to become effective and such Shelf
Registration Statement to become usable as soon as thereafter practicable. The
Company agrees to furnish to the Holders of Registrable Securities copies of any
such supplement or amendment promptly after its being used or filed with the
SEC.

         (c) The Company shall pay all Registration Expenses in connection with
the registration pursuant to Section 2(a) and 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. In the event the Exchange Offer is
not consummated or the Shelf Registration Statement is not declared effective on
or prior to the day that is 140 days following the date of the original issuance
of the Securities, the interest rate on the Securities will be increased by
0.50% per annum until the Exchange Offer is consummated or the Shelf
Registration Statement is declared effective by the SEC (such additional
interest, the "Special Interest").

         (e) Without limiting the remedies available to the Initial Purchasers
and the Holders, the Company acknowledges that any failure by the Company to
comply with its obligations under Section 2(a) and Section 2(b) hereof may
result in material irreparable injury to the Initial Purchasers or the Holders
for which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Section 2(a)
and Section 2(b) hereof.

         3. Registration Procedures.

requirements of Section 2 hereof):

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

Statement to become effective and remain effective in accordance with Section 2
hereof;

         (b) prepare and file with the SEC such amendments and post-effective

supplemented, to be filed pursuant to Rule 424 under the 1933 Act; to keep each
Prospectus current during the period described under Section 4(3) and Rule 174
under the 1933 Act that is applicable to transactions by brokers or dealers with
respect to the Registrable Securities or Exchange Securities;

         (c) in the case of a Shelf Registration, furnish to each Holder of

Securities, if any, without charge, as many copies of each Prospectus, including
each preliminary Prospectus, and any amendment or supplement thereto and such
other documents as such Holder or Underwriter may reasonably request, in order
to facilitate the public sale or other disposition of the Registrable
Securities; and the Company consents to the use of such Prospectus and any
amendment or supplement thereto in accordance with applicable law by each of the
selling Holders of Registrable Securities and any such Underwriters in
connection with the offering and sale of the Registrable Securities covered by
and in the manner described in such Prospectus or any amendment or supplement
thereto in accordance with applicable law;

         (d) use its best efforts to register or qualify the Registrable
Securities under all applicable state securities or "blue sky" laws of such
jurisdictions as any Holder of Registrable Securities covered by a Registration
Statement shall reasonably request in writing by the time the applicable
Registration Statement is declared effective by the SEC, to cooperate with such
Holders in connection with any filings required to be made with the National
Association of Securities Dealers, Inc. and do any and all other acts and things
which may be reasonably necessary or advisable to enable such Holder to
consummate the disposition in each such jurisdiction of such Registrable
Securities owned by such Holder; provided, however, that the Company shall not
be required to (i) qualify as a foreign corporation or as a dealer in securities
in any jurisdiction where it would not otherwise be required to qualify but for
this Section 3(d), (ii) file any general consent to service of process or (iii)
subject itself to taxation in any such jurisdiction if it is not so subject;

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

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

Holders of Registrable Securities to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not

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, prepare and file with the SEC a
supplement or post-effective amendment to a Registration Statement or the
related Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered to the purchasers of
the Registrable Securities, such Prospectus will not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading. The Company agrees to notify the Holders to suspend use of

                                        8
<PAGE>

the Prospectus as promptly as practicable after the occurrence of such an event,

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,

Securities satisfy applicable listing requirements;

Registrable Securities with respect to the business of the Company and its
subsidiaries, the Registration Statement, Prospectus and documents incorporated

Company, or of any business acquired by the Company for which financial
statements and financial data are or are required to be included in the
Registration Statement) addressed to each selling Holder and Underwriter of
Registrable Securities, such letters to be in customary form and covering
matters of the type customarily covered in "cold comfort" letters in connection
with primary 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 primary underwritten offerings, to
evidence the continued validity of the representations and warranties of the
Company made pursuant to clause (i) above and to evidence compliance with any
customary conditions contained in an underwriting agreement.

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

         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

                                       10
<PAGE>

Securities pursuant to a Registration Statement until such Holder's receipt of
the copies of the supplemented or amended Prospectus contemplated by Section
3(i) hereof, and, if so directed by the Company, such Holder will deliver to the
Company (at its expense) all copies in its possession, other than permanent file
copies then in such Holder's possession, of the Prospectus covering such
Registrable Securities current at the time of receipt of such notice. If the
Company shall give any such notice to suspend the disposition of Registrable
Securities pursuant to a Registration Statement, the Company shall extend the
period during which the Registration Statement shall be maintained effective
pursuant to this Agreement by the number of days during the period from and
including the date of the giving of such notice to and including the date when
the Holders shall have received copies of the supplemented or amended Prospectus
necessary to resume such dispositions. The Company may give any such notice only
twice during any 365 day period and any such suspensions may not exceed 30 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 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 Securities, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Securities owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the 1933
Act in connection with resales of Exchange Securities for their own accounts, so
long as the Prospectus otherwise meets the requirements of the 1933 Act.

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

                                       11

<PAGE>

                  (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 90 days after the last Exchange Date (as such period may be
         extended pursuant to the penultimate paragraph of Section 3 of this
         Agreement) and Participating Broker-Dealers shall not be authorized by
         the Company to deliver and shall not deliver such Prospectus after such
         period in connection with the resales contemplated by this Section 4;
         and

                  (ii) the application of the Shelf Registration procedures set
         forth in Section 3 of this Agreement to an Exchange Offer Registration,
         to the extent not required by the positions of the Staff of the SEC or
         the 1933 Act and the rules and regulations thereunder, will be in
         conformity with the reasonable request to the Company by the Initial
         Purchasers or with the reasonable request in writing to the Company by
         one or more broker-dealers who certify to the Initial Purchasers and
         the Company in writing that they anticipate that they will be
         Participating Broker-Dealers; and provided further that, in 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. unless it elects not to act as such representative, (y) to pay the
         fees and expenses of only one counsel representing the Participating
         Broker-Dealers, which shall be counsel to the Initial Purchasers unless
         such counsel elects not to so act and (z) to cause to be delivered only
         one, if any, "cold comfort" letter with respect to the Prospectus in
         the form existing on the last Exchange Date and with respect to each
         subsequent amendment or supplement, if any, effected during the period
         specified in clause (i) above.

                  (c) The Initial Purchasers shall have no liability to the
         Company or any Holder with respect to any request that it may make
         pursuant to Section 4(b) above.

          5. Indemnification and Contribution.

         (a) The Company agrees to indemnify and hold harmless the Initial
Purchasers, each Holder and each Person, if any, who controls any Initial
Purchaser or any Holder within the meaning of either Section 15 of the 1933 Act
or Section 20 of the 1934 Act, or is under common control with, or is controlled
by, any Initial Purchaser or any Holder, from and against all losses, claims,
damages and liabilities (including, without limitation, any legal or other
expenses reasonably incurred by the Initial Purchaser, any Holder or any such
controlling or affiliated Person in connection with defending or investigating
any such action or claim) caused by any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement (or any
amendment thereto) pursuant to which Exchange Securities or Registrable
Securities were registered under the 1933 Act, including all documents
incorporated therein by reference, or caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, or caused by any untrue statement or
alleged untrue statement of a material fact contained in any

                                       12

<PAGE>

Prospectus (as amended or supplemented if the Company shall have furnished any
amendments or supplements thereto), or caused by any omission or alleged
omission to state therein a material fact necessary to make the statements
therein in light of the circumstances under which they were made not misleading,
except insofar as such losses, claims, damages or liabilities are caused by any
such untrue statement or omission or alleged untrue statement or omission based
upon information relating to the Initial Purchasers or any Holder furnished to
the Company in writing by Deutsche Bank Securities Inc. or any selling Holder
expressly for use therein. In connection with any Underwritten Offering
permitted by Section 3, the Company 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 Company, the Initial Purchasers and the other selling Holders,
and each of their respective directors, officers who sign the Registration
Statement and each Person, if any, who controls the Company, any Initial
Purchaser and any other selling Holder within the meaning of either Section 15
of the 1933 Act or Section 20 of the 1934 Act to the same extent as the
foregoing indemnity from the Company to the Initial Purchasers and the Holders,
but only with reference to information relating to such Holder furnished to the
Company in writing by such Holder expressly for use in any Registration
Statement (or any amendment thereto) or any Prospectus (or any amendment or
supplement thereto).

         (c) In case any proceeding (including any governmental investigation)
shall be instituted involving any Person in respect of which indemnity may be
sought pursuant to either paragraph (a) or paragraph (b) above, such Person (the
"indemnified party") shall promptly notify the Person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. It is understood that the indemnifying party
shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for (a) the fees and expenses of more than one separate
firm (in addition to any local counsel) for the Initial Purchasers and all
Persons, if any, who control any Initial Purchaser within the meaning of either
Section 15 of the 1933 Act or Section 20 of the 1934 Act, (b) the fees and
expenses of more than one separate firm (in addition to any local counsel) for
the Company, its directors, its officers who sign the Registration Statement and
each Person, if any, who controls the Company within the meaning of either such
Section and (c) the fees and expenses of more than one separate firm (in
addition to any local

                                       13

<PAGE>

counsel) for all Holders and all Persons, if any, who control any Holders within
the meaning of either such Section, and that all such fees and expenses shall be
reimbursed as they are incurred. In such case involving the Initial Purchasers
and Persons who control the Initial Purchasers, such firm shall be designated in
writing by Deutsche Bank Securities Inc. 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 Company and the Holders shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or by the Holders
and the parties" relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Holders'
respective obligations to contribute pursuant to this Section 5(d) are several
in proportion to the respective principal amount of Registrable Securities of
such Holder that were registered pursuant to a Registration Statement.

         (e) The Company and each Holder agree that it would not be just or
equitable if contribution pursuant to this Section 5 were determined by pro rata
allocation or by any other method of allocation that does not take account of
the equitable considerations referred to in paragraph (d) above. The amount paid
or payable by an indemnified party as a result of the losses, claims, damages
and liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably

                                       14

<PAGE>

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

         The indemnity and contribution provisions contained in this Section 5
shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
the Initial Purchasers, any Holder or any Person controlling any Initial
Purchaser or any Holder, or by or on behalf of the Company, its officers or
directors or any Person controlling the Company, (iii) acceptance of any of the
Exchange Securities and (iv) any sale of Registrable Securities pursuant to a
Shelf Registration Statement.

         6. Miscellaneous.

         (a) No Inconsistent Agreements. The Company has not entered into, and
on or after the date of this Agreement will not enter into, any agreement which
is inconsistent with the rights granted to the Holders of Registrable Securities
in this Agreement or otherwise conflicts with the provisions hereof. The rights
granted to the Holders hereunder do not in any way conflict with and are not
inconsistent with the rights granted to the holders of the Company's other
issued and outstanding securities under any such agreements.

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

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

                                       15

<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 Purchase Agreement. If any transferee of any
Holder shall acquire Registrable Securities, in any manner, whether by operation
of law or otherwise, such Registrable Securities shall be held subject to all of
the terms of this Agreement, and by taking and holding such Registrable
Securities such Person shall be conclusively deemed to have agreed to be bound
by and to perform all of the terms and provisions of this Agreement and such
Person shall be entitled to receive the benefits hereof. The Initial Purchasers
(in their capacity as Initial Purchasers) shall have no liability or obligation
to the Company with respect to any failure by a Holder to comply with, or any
breach by any Holder of, any of the obligations of such Holder under this
Agreement.

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

         (f) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Initial Purchasers, 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 law of the
State of New York.

                                       16

<PAGE>

     (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.

         (k) Consent to Jurisdiction.

                  (i) The Company irrevocably submits to the nonexclusive
         jurisdiction of any court of the State of New York or any United States
         Federal court sitting in the Borough of Manhattan, the City of New
         York, New York, United States, and any appellate court from any
         thereof, and waives any immunity from the jurisdiction of such courts
         over any suit, action or proceeding that may be brought in connection
         with this Agreement. The Company irrevocably waives, to the fullest
         extent permitted by law, any objection to any suit, action, or
         proceeding that may be brought in connection with this Agreement in
         such courts whether on the grounds of venue, residence or domicile or
         on the ground that any such suit, action or proceeding has been brought
         in an inconvenient forum. The Company agrees that final judgment in any
         such suit, action or proceeding brought in such court shall be
         conclusive and binding upon the Company and may be enforced in any
         court to the jurisdiction of which the Company is subject by a suit
         upon such judgment; provided that service of process is effected upon
         the Company in the manner provided by this Agreement. Notwithstanding
         the foregoing, any suit, action or proceeding brought in connection
         with this Agreement against the Company may be instituted in any
         competent court in the Republic of Chile.

                  (ii) The Company agrees that service of all writs, process and
         summonses in any suit, action or proceeding brought in connection with
         this Agreement against the Company in any court of the State of New
         York or any United States Federal court, in each case, sitting in the
         Borough of Manhattan, The City of New York, may be made upon CT
         Corporation System at 111 Eighth Avenue, New York, New York 10011, whom
         the Company irrevocably appoints as its authorized agent for service of
         process. The Company represents and warrants that CT Corporation System
         has agreed to act as its agent for service of process. The Company
         agrees that such appointment shall be irrevocable until the irrevocable
         appointment by the Company, of a successor in The City of New York as
         its authorized agent for such purpose and the acceptance of such
         appointment by such successor. The Company further agrees to take any
         and all action, including the filing of any and all documents and
         instruments, that may be necessary to continue such appointment in full
         force and effect as aforesaid. If CT Corporation System shall cease to
         act as the agent for service of process for the Company, the Company
         shall appoint without delay another such agent and provide prompt
         written notice to the Initial Purchasers of such appointment. With
         respect to any such action in any court of the State of New York or any
         United States Federal court, in each case, in the Borough of Manhattan,
         The City of New York, service of process upon CT Corporation System, as
         the authorized agent of the Company for service of process, and written
         notice of such service to the

                                       17

<PAGE>

         Company shall be deemed, in every respect, effective service of process
         upon the Company.

                  (iii) Nothing in this Section shall affect the right of any
         party to serve legal process in any other manner permitted by law or
         affect the right of any party to bring any action or proceeding against
         any other party or its property in the courts of other jurisdictions.

         (l) Waiver of Immunity. To the extent that the Company or any of its
properties, assets or revenues may have or may hereafter become entitled to, or
have attributed to it, any right of immunity, on the grounds of sovereignty or
otherwise, from any legal action, suit or proceeding, from the giving of any
relief in any thereof, from setoff or counterclaim, from the jurisdiction of any
court, from service of process, from attachment upon or prior to judgment, from
attachment in aid of execution of judgment, or from execution of judgment, as
relief or for the enforcement of any judgment, in any jurisdiction in which the
proceedings may at any time be commenced, with respect to its obligations,
liabilities or any other matter under or arising out of or in connection with
this Agreement, the Company, to the fullest extent permitted by law, hereby
irrevocably and unconditionally waives and agrees not to plead or claim any such
immunity and consents to such relief and enforcement.
