          2.  Registration Under the Securities Act.

          (a) Except as set forth in Section 2(b) below, the Company agrees to
file under the Securities Act, as soon as practicable, but no later than 90 days
after the Closing

                                       4
<PAGE>

Date, a registration statement relating to an offer to exchange (such
registration statement, the "Exchange Registration Statement", and such offer,
the "Exchange Offer") any and all of the Securities for a like aggregate
principal amount of debt securities issued by the Company, which debt securities
are identical in all material respects, including but not limited to the minimum
denomination requirements set forth in Section 2.03 of the Indenture, to the
Securities (and are entitled to the benefits of a trust indenture which is
identical in all material respects to the Indenture or is the Indenture and
which has been qualified under the Trust Indenture Act), except that they have
been registered pursuant to an effective registration statement under the
Securities Act and do not contain provisions for the additional interest
contemplated in Section 2(c) below (such new debt securities hereinafter called
"Exchange Securities"). The Company agrees to use its best efforts to cause the
Exchange Registration Statement to become effective under the Securities Act as
soon as practicable, but no later than 150 days after the Closing Date, and to
use its best efforts to keep the Exchange Registration Statement effective until
the Exchange Offer is complete. The Exchange Offer will be registered under the
Securities Act on the appropriate form and will comply with all applicable
tender offer rules and regulations under the Exchange Act. The Company further
agrees to use its best efforts to complete the Exchange Offer promptly, but no
later than 180 days after the Closing Date, hold the Exchange Offer open for at
least 30 days (or longer if required by applicable law) after the date notice of
the Exchange Offer is mailed to holders of the Securities and exchange Exchange
Securities for all Registrable Securities that have been properly tendered and
not withdrawn on or prior to the expiration of the Exchange Offer. The Exchange
Offer will be deemed to have been "completed" only if the debt securities
received by holders other than Restricted Holders in the Exchange Offer for
Registrable Securities are, upon receipt, transferable by each such holder
without restriction under the Securities Act and the Exchange Act and without
material restrictions under the blue sky or securities laws of a substantial
majority of the States of the United States of America. The Exchange Offer shall
be deemed to have been completed upon the earlier to occur of (i) the Company
having exchanged the Exchange Securities for all outstanding Registrable
Securities pursuant to the Exchange Offer and (ii) the Company having exchanged,
pursuant to the Exchange Offer, Exchange Securities for all Registrable
Securities that have been properly tendered and not withdrawn before the
expiration of the Exchange Offer, which shall be on a date that is at least 30
days following the commencement of the Exchange Offer. The Company agrees (x) to
include in the Exchange Registration Statement a prospectus for use in any
resales by any holder of Exchange Securities that is a broker-dealer and (y) to
keep such Exchange Registration Statement effective for a period (the "Resale
Period") beginning when Exchange Securities are first issued in the Exchange
Offer and ending upon the earlier of the expiration of the 180th day after the
Exchange Offer has been completed or such time as such broker-dealers no longer
own any Registrable Securities and take any such other action as provided in
Section 3. With respect to such Exchange Registration Statement, such holders
shall have the benefit of the rights of indemnification and contribution set
forth in Sections 6(a), (c), (d) and (e) hereof.

          Each holder that participates in the exchange Securities in the
Exchange Offer will be required, as a condition to its participation in the
Exchange Offer, to represent to

                                       5
<PAGE>

the Company in writing (which may be contained in the applicable letter of
transmittal) (i) that such holder is not an affiliate of the Company within the
meaning of the Securities Act or a broker-dealer tendering Securities acquired
directly from the Company for its own account, (ii) that any Exchange Securities
to be received by it will be acquired in the ordinary course of its business,
(iii) that at the time of the commencement of the Exchange Offer such holder
will have no arrangement or understanding with any person to participate in the
distribution (within the meaning of the Securities Act) of the Exchange
Securities in violation of the provisions of the Securities Act and (iv) that
such holder is not acting on behalf of a person who could not make the foregoing
representations.

          (b) If (i) on or prior to the time the Exchange Offer is completed
existing laws, rules or Commission interpretations are changed such that the
Company is not permitted to consummate the Exchange Offer or the debt securities
received or to be received by any Electing Holder other than any Restricted
Holder in the Exchange Offer for Registrable Securities are not or would not be,
upon receipt, transferable by each such holder without restriction under the
Securities Act, (ii) the Exchange Offer has not been completed within 180 days
following the Closing Date, (iii) any of the Purchasers so requests if such
Purchaser holds Securities acquired as part of an unsold allotment or as to
which such Purchaser does not believe it would receive freely transferable
securities if it exchanged its Securities in the Exchange Offer or (iv) any
holder of Registrable Securities so requests if such holder is not permitted,
because of a change in applicable laws, rules or Commission interpretations, to
participate in the Exchange Offer, the Company shall, in lieu of (or, in the
case of clause (iv), in addition to) conducting the Exchange Offer contemplated
by Section 2(a), file under the Securities Act as soon as practicable, but no
later than 60 days after the time such obligation to file arises (upon the
earliest to occur of (i) through (iv) above), a "shelf" registration statement
providing for the registration of, and the sale on a continuous or delayed basis
by the holders of, all of the Registrable Securities, pursuant to Rule 415 or
any similar rule that may be adopted by the Commission (such filing, the "Shelf
Registration" and such registration statement, the "Shelf Registration
Statement"). The Company agrees to use its best efforts (x) to cause the Shelf
Registration Statement to become or be declared effective by the 60th day after
such Shelf Registration Statement is filed but in no event later than 210 days
after the Closing Date and to keep such Shelf Registration Statement
continuously effective for a period ending on the earlier of the second
anniversary of the Effective Time or such time as there are no longer any
Registrable Securities outstanding, provided, however, that no holder shall be
entitled to be named as a selling securityholder in the Shelf Registration
Statement or to use the prospectus forming a part thereof for resales of
Registrable Securities unless such holder is an Electing Holder, and (y) after
the Effective Time of the Shelf Registration Statement, promptly upon the
request of any holder of Registrable Securities that is not then an Electing
Holder, to take any action reasonably necessary to enable such holder to use the
prospectus forming a part thereof for resales of Registrable Securities,
including, without limitation, any action necessary to identify such holder as a
selling securityholder in the Shelf Registration Statement, provided, however,
that nothing in this clause (y) shall relieve any such holder of the obligation
to return a completed and signed Notice and Questionnaire to the Company in
accordance with Section 3(d)(iii) hereof.

                                       6
<PAGE>

The Company further agrees to supplement or make amendments to the Shelf
Registration Statement, as and when required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or by the Securities Act or rules and regulations
thereunder for shelf registration, and the Company agrees to furnish to each
Electing Holder copies of any such supplement or amendment prior to its being
used or promptly following its filing with the Commission.

          (c) In the event that (i) the Company has not filed the Exchange
Registration Statement or Shelf Registration Statement on or before the date on
which such registration statement is required to be filed pursuant to Section
2(a) or 2(b), respectively, (ii) such Exchange Registration Statement or Shelf
Registration Statement has not become effective or been declared effective by
the Commission on or before the date on which such registration statement is
required to become or be declared effective pursuant to Section 2(a) or 2(b),
respectively, (iii) the Exchange Offer has not been completed on or prior to the
180th day following the Closing Date (if the Exchange Offer is then required to
be made) or (iv) any Exchange Registration Statement required by 2(a) or Shelf
Registration Statement required by Section 2(b) is declared effective but shall
thereafter either be withdrawn by the Company, become unusable or become subject
to an effective stop order issued pursuant to Section 8(d) of the Securities Act
suspending the effectiveness of such registration statement such that it is not
effective for the period required by Section 2(a) or Section 2(b), without, in
the case of a Shelf Registration Statement, an additional shelf registration
statement being declared effective, for more than 45 days in the aggregate in
any 12-month period (each such event referred to in clauses (i) through (iv), a
"Registration Default"), then, as liquidated damages for such Registration
Default, subject to the provisions of Section 9(b), special interest ("Special
Interest"), in addition to the Base Interest, shall accrue on the aggregate
principal amount of the outstanding Securities at a per annum rate of 0.25% upon
the occurrence of each Registration Default, which Special Interest rate will
increase by an additional per annum rate of 0.25% each 90-day period that such
Registration Default continues under any such circumstances, with an aggregate
maximum per annum Special Interest rate of 2.0%. All accrued Special Interest
shall be paid in cash by the Company on each Interest Payment Date (as defined
in the Indenture). Following the cure of all Registration Defaults, the accrual
of Special Interest will cease. Upon any Registration Default, so long as the
Securities are listed in the Luxembourg Stock Exchange or another exchange and
the rules of such exchange so require, the Company shall provide a notice in a
publication with circulation in Luxembourg describing such event giving rise to
the obligation to pay Special Interest.

          (d) The Company shall take all actions necessary or advisable to be
taken by it to ensure that the transactions contemplated herein are effected as
so contemplated, including all actions necessary or desirable to register the
Guarantee under the Registration Statement contemplated in Section 2(a) or 2(b)
hereof, as applicable, to the extent the Guarantee, by its terms, requires the
maintenance of the Guarantee at such time.

          (e) Any reference herein to a registration statement as of any time
shall be deemed to include any document incorporated, or deemed to be
incorporated, therein by

                                       7
<PAGE>

reference as of such time and any reference herein to any post-effective
amendment to a registration statement as of any time shall be deemed to include
any document incorporated, or deemed to be incorporated, therein by reference as
of such time.

          3.  Registration Procedures.

          If the Company files a registration statement pursuant to Section 2(a)
or Section 2(b), the following provisions shall apply:

          (a) At or before the Effective Time of the Exchange Offer or the Shelf
Registration, as the case may be, the Company shall qualify the Indenture under
the Trust Indenture Act of 1939.

          (b) In the event that such qualification would require the appointment
of a new trustee under the Indenture, the Company shall appoint a new trustee
thereunder pursuant to the applicable provisions of the Indenture.

          (c) In connection with the Company's obligations with respect to the
registration of Exchange Securities as contemplated by Section 2(a) (the
"Exchange Registration"), if applicable, the Company shall, as soon as
practicable (or as otherwise specified):

          (i) prepare and file with the Commission, as soon as practicable but
     no later than 90 days after the Closing Date, an Exchange Registration
     Statement on any form which may be utilized by the Company and which shall
     permit the Exchange Offer and resales of Exchange Securities by broker-
     dealers during the Resale Period to be effected as contemplated by Section
     2(a), and use its best efforts to cause such Exchange Registration
     Statement to become effective as soon as practicable thereafter, but no
     later than 150 days after the Closing Date;

          (ii) as soon as practicable prepare and file with the Commission such
     amendments and supplements to such Exchange Registration Statement and the
     prospectus included therein as may be necessary to effect and maintain the
     effectiveness of such Exchange Registration Statement for the periods and
     purposes contemplated in Section 2(a) hereof and as may be required by the
     applicable rules and regulations of the Commission and the instructions
     applicable to the form of such Exchange Registration Statement, and
     promptly provide each broker-dealer holding Exchange Securities with such
     number of copies of the prospectus included therein (as then amended or
     supplemented), in conformity in all material respects with the requirements
     of the Securities Act and the Trust Indenture Act and the rules and
     regulations of the Commission thereunder, as such broker-dealer reasonably
     may request prior to the expiration of the Resale Period, for use in
     connection with resales of Exchange Securities;

                                       8
<PAGE>

          (iii) promptly notify each broker-dealer that has requested or
     received copies of the prospectus included in such registration statement,
     and confirm such advice in writing, (A) when such Exchange Registration
     Statement or the prospectus included therein or any prospectus amendment or
     supplement or post-effective amendment has been filed, and, with respect to
     such Exchange Registration Statement or any post-effective amendment, when
     the same has become effective, (B) of any comments by the Commission and by
     the blue sky or securities commissioner or regulator of any state with
     respect thereto or any request by the Commission for amendments or
     supplements to such Exchange Registration Statement or prospectus or for
     additional information, (C) of the issuance by the Commission of any stop
     order suspending the effectiveness of such Exchange Registration Statement
     or the initiation or threatening of any proceedings for that purpose, (D)
     if at any time the representations and warranties of the Company
     contemplated by Section 5 cease to be true and correct in all material
     respects, (E) of the receipt by the Company of any notification with
     respect to the suspension of the qualification of the Exchange Securities
     for sale in any jurisdiction or the initiation or threatening of any
     proceeding for such purpose, or (F) at any time during the Resale Period
     when a prospectus is required to be delivered under the Securities Act,
     that such Exchange Registration Statement, prospectus, prospectus amendment
     or supplement or post-effective amendment does not conform in all material
     respects to the applicable requirements of the Securities Act and the Trust
     Indenture Act and the rules and regulations of the Commission thereunder or
     contains an untrue statement of a material fact or omits to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading in light of the circumstances then
     existing;

          (iv) in the event that the Company would be required, pursuant to
     Section 3(c)(iii)(F) above, to notify any broker-dealers holding Exchange
     Securities, without delay prepare and furnish to each such holder a
     reasonable number of copies of a prospectus supplemented or amended so
     that, as thereafter delivered to purchasers of such Exchange Securities
     during the Resale Period, such prospectus shall conform in all material
     respects to the applicable requirements of the Securities Act and the Trust
     Indenture Act and the rules and regulations of the Commission thereunder
     and shall not contain an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in light of the circumstances then
     existing;

          (v) use its best efforts to obtain the withdrawal of any order
     suspending the effectiveness of such Exchange Registration Statement or any
     post-effective amendment thereto at the earliest practicable date;

                                       9
<PAGE>

          (vi) use its best efforts to (A) register or qualify the Exchange
     Securities under the securities laws or blue sky laws of such jurisdictions
     as are contemplated by Section 2(a) no later than the commencement of the
     Exchange Offer, (B) keep such registrations or qualifications in effect and
     comply with such laws so as to permit the continuance of offers, sales and
     dealings in such jurisdictions until the expiration of the Resale Period
     and (C) take any and all other actions as may be reasonably necessary or
     advisable to enable each broker-dealer holding Exchange Securities to
     consummate the disposition thereof in such jurisdictions; provided,
     however, that the Company shall not be required for any such purpose to (1)
     qualify as a foreign corporation in any jurisdiction wherein it would not
     otherwise be required to qualify but for the requirements of this Section
     3(c)(vi), (2) consent to general service of process in any such
     jurisdiction or (3) make any changes to its articles of association or
     other constituent documents or any agreement between it and its

     governmental agency or authority, whether federal, state or local, which
     may be required to effect the Exchange Registration, the Exchange Offer and
     the offering and sale of Exchange Securities by broker-dealers during the
     Resale Period;

          (viii) provide a CUSIP number for all Exchange Securities, not later
     than the applicable Effective Time;

          (ix) so long as the Securities are listed on the Luxembourg Stock
     Exchange or another exchange, and the rules of such exchange so require,
     prior to the Exchange Offer, provide a notice in a leading newspaper having
     general circulation in Luxembourg (which is expected to be the Luxemburger
     Wort) indicating the proceedings to be followed in connection with the
     Exchange Offer; and

          (x) comply with all applicable rules and regulations of the
     Commission, and make generally available to its securityholders as soon as
     practicable but no later than eighteen months after the effective date of
     such Exchange Registration Statement, an earning statement of the Company
     and its subsidiaries complying with Section 11(a) of the Securities Act
     (including, at the option of the Company, Rule 158 thereunder).

local counsel) for the Electing Holders retained in connection with a Shelf
Registration, as selected by the Electing Holders of at least a majority in
aggregate principal amount of the Registrable Securities held by Electing
Holders (which counsel shall be reasonably satisfactory to the Company), (j) any
fees charged by securities rating services for rating the Securities, (k) fees,
expenses and disbursements of any other persons, including special experts,
retained by the Company in connection with such registration and (l) fees and
expenses incurred in connection with the listing of the Securities or Exchange
Securities on any securities exchange, including the listing on the Luxembourg

any Registration Expenses are incurred, assumed or paid by any holder of
Registrable Securities or any placement or sales agent therefor or underwriter
thereof, the Company shall reimburse such person for the full amount of the
Registration Expenses so incurred, assumed or paid promptly after receipt of a
request therefor. Notwithstanding the foregoing, the holders of the Registrable
Securities being registered shall pay all agency fees and commissions and
underwriting discounts and commissions attributable to the sale of such
Registrable Securities and the fees and disbursements of any counsel or other
advisors or experts retained by such holders (severally or jointly), other than
the counsel and experts specifically referred to above.

        5.  Representations and Warranties.

        The Company represents and warrants to, and agrees with, each Purchaser
and each of the holders from time to time of Registrable Securities that:

        (a) Each registration statement covering Registrable Securities and each
prospectus (including any preliminary or summary prospectus) contained therein
or furnished pursuant to Section 3(d) or Section 3(c) hereof and any further
amendments or supplements to any such registration statement or prospectus, when
it becomes effective or is filed with the Commission, as the case may be, and,
in the case of an underwritten offering of Registrable Securities, at the time
of the closing under the underwriting agreement relating thereto, will conform
in all material respects to the requirements of the Securities Act and the Trust

                                       20
<PAGE>

Indenture Act and the rules and regulations of the Commission thereunder and
will not contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; and at all times subsequent to the Effective Time when a
prospectus would be required to be delivered under the Securities Act, other
than from (i) such time as a notice has been given to holders of Registrable
Securities pursuant to Section 3(d)(viii)(F) or Section 3(c)(iii)(F) hereof
until (ii) such time as the Company furnishes an amended or supplemented
prospectus pursuant to Section 3(e) or Section 3(c)(iv) hereof, each such
registration statement, and each prospectus (including any summary prospectus)
contained therein or furnished pursuant to Section 3(d) or Section 3(c) hereof,
as then amended or supplemented, will conform in all material respects to the
requirements of the Securities Act and the Trust Indenture Act and the rules and
regulations of the Commission thereunder and will not contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing; provided, however, that this
representation and warranty shall not apply to any statements or omissions made
in reliance upon and in conformity with information furnished in writing to the
Company by a holder of Registrable Securities relating to such holder expressly
for use therein.

        (b) Any documents incorporated by reference in any prospectus referred
to in Section 5(a) hereof, when they become or became effective or are or were
filed with the Commission, as the case may be, will conform or conformed in all
material respects to the requirements of the Securities Act or the Exchange Act,
as applicable, and none of such documents will contain or contained an untrue
statement of a material fact or will omit or omitted to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading; provided, however, that this representation and warranty shall not
apply to any statements or omissions made in reliance upon and in conformity
with information furnished in writing to the Company by a holder of Registrable
Securities expressly for use therein.

        (c) The compliance by the Company with all of the provisions of this
Exchange and Registration Rights Agreement and the consummation of the
transactions herein contemplated will not conflict with or result in a breach of
any of the terms or provisions of, or constitute a default under, any indenture,
mortgage, deed of trust, loan agreement, lease, license, permit or other
material agreement or instrument to which the Company or any subsidiary of the
Company is a party or by which the Company or any subsidiary of the Company is
bound or to which any of the property or assets of the Company or any subsidiary
of the Company is subject, nor will such action result in any violation of the
provisions of the articles of association or other constituent documents, as
amended, of the Company or any statute or any order, rule or regulation of any
court or governmental agency or body having jurisdiction over the Company or any
subsidiary of the Company or any of their properties; and no consent, approval,
authorization, order, registration or qualification of or with any such court or
governmental agency or body is required for the consummation by the Company of
the transactions contemplated by this Exchange and Registration Rights
Agreement,

                                       21
<PAGE>

except the registration under the Securities Act of the Securities,
qualification of the Indenture under the Trust Indenture Act and such consents,
approvals, authorizations, registrations or qualifications as may be required
under State securities or blue sky laws in connection with the offering and
distribution of the Securities.

        (d) This Exchange and Registration Rights Agreement has been duly
authorized, executed and delivered by the Company.

        6.  Indemnification.

        (a) Indemnification by the Company. The Company will indemnify and hold
harmless each of the holders of Registrable Securities included in an Exchange
Registration Statement, each of the Electing Holders of Registrable Securities
included in a Shelf Registration Statement and each person who participates as a
placement or sales agent or as an underwriter in any offering or sale of such
Registrable Securities against any losses, claims, damages or liabilities, joint
or several, to which such holder, agent or underwriter may become subject under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Exchange Registration Statement or Shelf Registration Statement, as the case may
be, under which such Registrable Securities were registered under the Securities
Act, or any preliminary, final or summary prospectus contained therein or
furnished by the Company to any such holder, Electing Holder, agent or
underwriter, or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse such holder, such Electing Holder, such agent and
such underwriter for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such action or claim as such
expenses are incurred; provided, however, that the Company shall not be liable
to any such person in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in such
registration statement, or preliminary, final or summary prospectus, or
amendment or supplement thereto, in reliance upon and in conformity with written
information furnished to the Company by such person expressly for use therein.

        (b) Indemnification by the Holders and any Agents and Underwriters. The
Company may require, as a condition to including any Registrable Securities in
any registration statement filed pursuant to Section 2(b) hereof and to entering
into any underwriting agreement with respect thereto, that the Company shall
have received an undertaking reasonably satisfactory to it from each Electing
Holder of such Registrable Securities and from each underwriter named in any
such underwriting agreement, severally and not jointly, to (i) indemnify and
hold harmless the Company and all other holders of Registrable Securities
against any losses, claims, damages or liabilities to which the Company or such
other holders of Registrable Securities may become subject, under the Securities
Act or otherwise, in-

                                       22
<PAGE>

sofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in such registration statement, or any
preliminary, final or summary prospectus contained therein or furnished by the
Company to any such Electing Holder, agent or underwriter, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Electing
Holder relating to such holder or underwriter expressly for use therein, and
(ii) reimburse the Company for any legal or other expenses reasonably incurred
by the Company in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that no such Electing
Holder shall be required to undertake liability to any person under this Section
6(b) for any amounts in excess of the amount of the proceeds to be received by
such Electing Holder from the sale of such Electing Holder's Registrable
Securities pursuant to such registration.

        (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
party under subsection (a) or (b) above of written notice of the commencement of
any action, such indemnified party shall, if a claim in respect thereof is to be
made against an indemnifying party pursuant to the indemnification provisions of
or contemplated by this Section 6, notify such indemnifying party in writing of
the commencement of such action; but the omission so to notify the indemnifying
party shall not relieve it from any liability which it may have to any
indemnified party otherwise than under the indemnification provisions of or
contemplated by Section 6(a) or 6(b) hereof. In case any such action shall be
brought against any indemnified party and it shall notify an indemnifying party
of the commencement thereof, such indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any
other indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, such indemnifying party shall
not be liable to such indemnified party for any legal expenses of other counsel
or any other expenses, in each case subsequently incurred by such indemnified
party, in connection with the defense thereof other than reasonable costs of
investigation. No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or claim
in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to or an admission
of fault, culpability or a failure to act by or on behalf of any indemnified
party.

                                       23
<PAGE>

        (d) Contribution. If for any reason the indemnification provisions
contemplated by Section 6(a) or Section 6(b) are unavailable to or insufficient
to hold harmless an indemnified party in respect of any losses, claims, damages
or liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and the indemnified party in connection
with the statements or omissions which resulted in such losses, claims, damages
or liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contributions pursuant to this Section 6(d) were determined by
pro rata allocation (even if the holders or any agents or underwriters or all of
them were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations referred
to in this Section 6(d). The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, or liabilities (or actions in respect
thereof) referred to above shall be deemed to include any legal or other fees or
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 6(d), no holder shall be required to contribute any
amount in excess of the amount by which the amount of the proceeds received by
such holder from the sale of any Registrable Securities (after deducting any
fees, discounts and commissions applicable thereto) exceeds the amount of any
damages which such holder has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission, and no
underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Registrable Securities underwritten by it
and distributed to the public were offered to the public exceeds the amount of
any damages which such underwriter 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 Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The holders' and any
underwriters' obligations in this Section 6(d) to contribute shall be several in
proportion to the principal amount of Registrable Securities registered or
underwritten, as the case may be, by them and not joint.

        (e) The obligations of the Company under this Section 6 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each officer, director and partner of
each holder, agent and underwriter and each person, if any, who controls any
holder, agent or underwriter within the meaning of the Securities Act; and the
obligations of the holders and any agents or underwriters contemplated by this
Section 6 shall be in addition to any liability which the respective

                                       24
<PAGE>

holder, agent or underwriter may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company (including any
person who, with his consent, is named in any registration statement as about to
become a director of the Company) and to each person, if any, who controls the
Company within the meaning of the Securities Act.

        7.  Underwritten Offerings.

        (a) Selection of Underwriters. If any of the Registrable Securities
covered by the Shelf Registration are to be sold pursuant to an underwritten
offering, the managing underwriter or underwriters thereof shall be designated
by Electing Holders holding at least a majority in aggregate principal amount of
the Registrable Securities to be included in such offering, provided that such
designated managing underwriter or underwriters is or are reasonably acceptable
to the Company.

        (b) Participation by Holders. Each holder of Registrable Securities
hereby agrees with each other such holder that no such holder may participate in
any underwritten offering hereunder unless such holder (i) agrees to sell such
holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

        8.  Rule 144.

        The Company covenants to the holders of Registrable Securities that to
the extent it shall be required to do so under the Exchange Act, the Company
shall timely file the reports required to be filed by it under the Exchange Act
or the Securities Act (including the reports under Section 13 and 15(d) of the
Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted by the
Commission under the Securities Act) and the rules and regulations adopted by
the Commission thereunder, and shall take such further action as any holder of
Registrable Securities may reasonably request, all to the extent required from
time to time to enable such holder to sell Registrable Securities without
registration under the Securities Act within the limitations of the exemption
provided by Rule 144 under the Securities Act, as such Rule may be amended from
time to time, or any similar or successor rule or regulation hereafter adopted
by the Commission. Upon the request of any holder of Registrable Securities in
connection with that holder's sale pursuant to Rule 144, the Company shall
deliver to such holder a written statement as to whether it has complied with
such requirements.

        9.  Miscellaneous.

        (a) No Inconsistent Agreements. The Company represents, warrants,
covenants and agrees that it has not granted, and shall not grant, registration
rights with respect to Registrable Securities or any other securities which
would be inconsistent with the terms contained in this Exchange and Registration
Rights Agreement.

                                       25
<PAGE>

        (b) Specific Performance. The parties hereto acknowledge that there
would be no adequate remedy at law if the Company fails to perform any of its
obligations hereunder and that the Purchasers and the holders from time to time
of the Registrable Securities may be irreparably harmed by any such failure, and
accordingly agree that the Purchasers and such holders, in addition to any other
remedy to which they may be entitled at law or in equity, shall be entitled to
compel specific performance of the obligations of the Company under this
Exchange and Registration Rights Agreement in accordance with the terms and
conditions of this Exchange and Registration Rights Agreement, in any court of
the United States or any State thereof having jurisdiction.

        (c) Notices. All notices, requests, claims, demands, waivers and other
communications hereunder shall be in writing and shall be deemed to have been
duly given when delivered by hand, if delivered personally or by courier, or

postage prepaid, return receipt requested) as follows: If to the Company, to it

        (d) Parties in Interest. All the terms and provisions of this Exchange
and Registration Rights Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the parties hereto and the holders from
time to time of the Registrable Securities and the respective successors and
assigns of the parties hereto and such holders. In the event that any transferee
of any holder of Registrable Securities shall acquire Registrable Securities, in
any manner, whether by gift, bequest, purchase, operation of law or otherwise,
such transferee shall, without any further writing or action of any kind, be
deemed a beneficiary hereof for all purposes and such Registrable Securities
shall be held subject to all of the terms of this Exchange and Registration
Rights Agreement, and by taking and holding such Registrable Securities such
transferee shall be entitled to receive the benefits of, and be conclusively
deemed to have agreed to be bound by all of the applicable terms and provisions
of this Exchange and Registration Rights Agreement. If the Company shall so
request, any such successor, assign or transferee shall agree in writing to
acquire and hold the Registrable Securities subject to all of the applicable
terms hereof.

        (e) Survival. The respective indemnities, agreements, representations,
warranties and each other provision set forth in this Exchange and Registration
Rights Agreement or made pursuant hereto shall remain in full force and effect
regardless of any investigation (or statement as to the results thereof) made by
or on behalf of any holder of Registrable Securities, any director, officer or
partner of such holder, any agent or under-

                                       26
<PAGE>

writer or any director, officer or partner thereof, or any controlling person of
any of the foregoing, and shall survive delivery of and payment for the
Registrable Securities pursuant to the Purchase Agreement and the transfer and
registration of Registrable Securities by such holder and the consummation of an
Exchange Offer.

        (f) Governing Law. This Exchange and Registration Rights Agreement shall
be governed by and construed in accordance with the laws of the State of New
York, without giving effect to applicable principles of conflicts of laws to the
extent that the application of the law of another jurisdiction would be required
thereby.

        (g) Headings. The descriptive headings of the several Sections and
paragraphs of this Exchange and Registration Rights Agreement are inserted for
convenience only, do not constitute a part of this Exchange and Registration
Rights Agreement and shall not affect in any way the meaning or interpretation
of this Exchange and Registration Rights Agreement.

        (h) Entire Agreement; Amendments. This Exchange and Registration Rights
Agreement and the other writings referred to herein (including the Indenture and
the form of Securities) or delivered pursuant hereto which form a part hereof
contain the entire understanding of the parties with respect to its subject
matter. This Exchange and Registration Rights Agreement supersedes all prior
agreements and understandings between the parties with respect to its subject
matter. This Exchange and Registration Rights Agreement may be amended and the
observance of any term of this Exchange and Registration Rights Agreement may be
waived (either generally or in a particular instance and either retroactively or
prospectively) only by a written instrument duly executed by the Company and the
holders of at least a majority in aggregate principal amount of the Registrable
Securities at the time outstanding. Each holder of any Registrable Securities at
the time or thereafter outstanding shall be bound by any amendment or waiver
effected pursuant to this Section 9(h), whether or not any notice, writing or
marking indicating such amendment or waiver appears on such Registrable
Securities or is delivered to such holder.

        (i) Inspection. For so long as this Exchange and Registration Rights
Agreement shall be in effect, this Exchange and Registration Rights Agreement
and a complete list of the names and addresses of all the holders of Registrable
Securities shall be made available for inspection and copying on any business
day by any holder of Registrable Securities for proper purposes only (which
shall include any purpose related to the rights of the holders of Registrable
Securities under the Securities, the Indenture and this Agreement) at the
offices of the Company at the address thereof set forth in Section 9(c) above
and at the office of the Trustee under the Indenture.

        (j) Jurisdiction; Immunity. By the execution and delivery of this
Exchange and Registration Rights Agreement, the Company (i) acknowledges that it
has, by separate written instrument, designated and appointed CT Corporation
System (the "Process Agent"), 1633 Broadway, New York, New York 10019, United
             -------------
States, as its authorized agent upon

                                       27
<PAGE>

which process may be served in any suit, action or proceeding arising out of or
relating to this Agreement that may be instituted in any Federal or state court
in the State of New York, The City of New York, the Borough of Manhattan, or
brought under Federal or state securities laws or brought by the holders of the
Securities or Exchange Securities, and acknowledges that the Process Agent has
accepted such designation, (ii) submits to the jurisdiction of any such court in
any such suit, action or proceeding and (iii) agrees that service of process
upon the Process Agent and written notice of said service to it at its principal
office in accordance with Section 9(c), shall be deemed in every respect
effective service of process upon it in any such suit or proceeding. The Company
further agrees to take any and all action, including the execution and filing of
any and all such documents and instruments as may be necessary to continue such
designation and appointment of the Process Agent in full force and effect so
long as the Securities or Exchange Securities shall be outstanding; provided
that the Company may (and shall, to the extent the Process Agent ceases to be
able to be served on the basis contemplated herein) by written notice to the
Trustee, designate such additional or alternative agents for service of process
under this Section 9(j) that (i) maintain an office located in the Borough of
Manhattan, The City of New York in the State of New York, (ii) are either (x)
counsel for the Company or (y) a corporate service company which acts as agent
for service of process for other Persons in the ordinary course of its business
and (iii) agree to act as agent for service of process in accordance with this
Section 9(j). Such notice shall identify the name of such agent for process and
the address of such agent for process in the Borough of Manhattan, The City of
New York, State of New York. Notwithstanding the foregoing, there shall, at all
times, be at least one agent for service of process for the Company appointed
and acting in accordance with this Section 9(j).

        To the extent that the Company has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether
through service of notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property, it
hereby irrevocably waives such immunity in respect of its obligations under the
above-referenced documents, to the extent permitted by law.

        (k)  Currency.  Each reference in this Exchange and Registration Rights
Agreement to any payment, indemnification or contribution obligation refers
to amounts in euros (the "relevant currency") and is of the essence.  To the
                          -----------------
fullest extent permitted by law, the obligations of the Company in respect of
any amount due under this Exchange and Registration Right Agreement will,
notwithstanding any payment in any other currency (whether pursuant to a
judgment or otherwise), be discharged only to the extent of the amount in the
relevant currency that the party entitled to receive such payment may, in
accordance with its normal procedures, purchase with the sum paid in such other
currency (after any premium and costs of exchange) on the business day
immediately following the day on which such party receives such payment. If the
amount in the relevant currency that may be so purchased for any reason falls
short of the amount originally due, the Company will pay such additional
amounts, in the relevant currency, as may be necessary to compensate for the
shortfall. If, alternatively, the amount in the relevant currency that may be so
purchased for any reason exceeds the amount originally due, the party entitled
to receive such original

                                       28
<PAGE>

amount will return such excess amounts, in the relevant currency, to the
Company. Any obligation of the Company not discharged by such payment will, to
the fullest extent permitted by applicable law, be due as a separate and
independent obligation and, until discharged as provided herein, will continue
in full force and effect.

        (l) Counterparts. This agreement may be executed by the parties in
counterparts, each of which shall be deemed to be an original, but all such
respective counterparts shall together constitute one and the same instrument.

                                       29
<PAGE>

          If the foregoing is in accordance with your understanding, please sign
and return to us seven counterparts hereof, and upon the acceptance hereof by
you, on behalf of each of the Purchasers, this letter and such acceptance hereof
shall constitute a binding agreement between each of the Purchasers and the
Company.  It is understood that your acceptance of this letter on behalf of each
of the Purchasers is pursuant to the authority set forth in a form of Agreement
among Purchasers, the form of which shall be submitted to the Company for
examination upon request, but without warranty on your part as to the authority
of the signers thereof.

                                      Very truly yours,
