         under the Act or, with respect to Securities sold outside the United
         States (as defined in Rule 902 under the Act), by means of any directed
         selling efforts within the meaning of Rule 902 under the Act;

                  (r) To comply, and to ensure that each of its affiliates and
         each person acting on its or their behalf has complied and will comply,
         with the "offering restrictions" (described in the Offering Circular)
         within the meaning of Rule 903 under the Act;

                  (s) Not to offer, sell, publicly promote or advertise and to
         use its best efforts to ensure that its affiliates and any person
         acting on its behalf (other than the Purchasers) has not offered, sold,
         publicly promoted or advertised and will not offer, sell, publicly
         promote or advertise, directly or indirectly, any Securities in Germany
         other than in compliance with the German Securities Selling Prospectus
         Act (WERTPAPIERVERKAUFSPROSPEKTGESETZ) of 13th December, 1990, as
         amended, or any other laws applicable in Germany governing the issue,
         offering and sale of securities; and

                  (t) To pay any amounts due as a result of any value added
         taxes ("VAT") payable by the Purchasers in respect of commissions

         reimbursable by the Company pursuant to this Agreement.

         6. The Company covenants and agrees with the several Purchasers that
the Company will pay or cause to be paid the following: (i) the fees,

         satisfactory to you;

                  (k) Neither the Company nor any of its subsidiaries shall have
         sustained since the date of the latest audited financial statements
         included in the Offering Circular any loss or interference with its
         business from fire, explosion, flood or other calamity, whether or not
         covered by insurance, or from any labor dispute or court or
         governmental or quasi-governmental action, order or decree, otherwise
         than as set forth in the Offering Circular, and (ii) since the
         respective dates as of which information is given in the Offering
         Circular there shall not have been any change in the capital stock or
         long-term debt of the Company or any of its subsidiaries or any change,
         or any development involving a prospective change, in or affecting the
         general affairs, management, financial position, business prospects,
         shareholders' equity or results of operations of the Company and its
         subsidiaries, otherwise than as set forth in the Offering Circular, the
         effect of which, in any such case described in clause (i) or (ii), is
         in the judgment of the Representative so material and adverse as to
         make it impracticable or inadvisable to proceed with the offering or
         the delivery of the Securities on the terms and in the manner
         contemplated in the Offering Circular;

                  (l) On or after the date hereof there shall not have occurred
         any of the following: (i) a suspension or material limitation in
         trading in securities generally on the New York Stock Exchange, the
         Frankfurt Stock Exchange, or the Luxembourg Stock Exchange; (ii) a
         suspension or material limitation in trading in the Company's

         existing financial, political or economic conditions in the United
         States, Germany or elsewhere; provided that, with respect to clauses
         (iv), (v) and (vi) above, the effect of any such event specified in
         such clauses (iv), (v) or (vi), in the judgment of the Representative,
         makes it impracticable or inadvisable to proceed with the offering or
         the delivery of the Securities on the terms and in the manner
         contemplated in the Offering Circular;

                  (m) At the Time of Delivery, Allen & Overy shall have been
         furnished with such information, certificates and documents as it may
         reasonably require for the purpose of enabling it to pass upon the
         issuance and sale of the Securities as contemplated herein and


                                       16
<Page>

         related proceedings, and in order to evidence the accuracy of any of
         the representations or warranties, or the fulfillment of any of the
         conditions, herein contained;

                  (n) the Representative shall have received a counterpart,
         conformed as executed, of the Indenture, the Assignment and each of the
         High Yield Structure Document to which the Trustee is or will be a
         party which shall have been entered into by the Company and the
         Trustee;

                  (o) The Company shall have executed the Registration Rights
         Agreement as set forth in the Offering Circular with such other terms
         as shall be mutually satisfactory and the Representative shall have
         received an original copy thereof, duly executed by the Company;

                  (p) The Securities have been accepted for listing on the
         Luxembourg Stock Exchange;

                  (q) The Company and each other party thereto shall have
         executed the Assignment Agreement and each of the High Yield Structure
         Documents in the respective forms previously delivered to you and the
         Representative shall have received a copy, conformed as executed, of
         each, duly executed by the parties thereto; and

                  (r) The Company shall have furnished or caused to be furnished
         to you at the Time of Delivery certificates of officers of the Company
         satisfactory to you as to the accuracy of the representations and
         warranties of the Company herein at and as of such Time of Delivery, as
         to the performance by the Company of all of its obligations hereunder
         to be performed at or prior to such Time of Delivery, as to the matters
         set forth in subsections (e) through (h) of this Section and as to such
         other matters as you may reasonably request.

         8.       (a) The Company will indemnify and hold harmless each
Purchaser against any losses, claims, damages or liabilities, joint or several,
to which such Purchaser may become subject, under the 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 Preliminary Offering Circular, the Offering
Circular, or any Registration Statement or Market Making Shelf Registration
Statement (as defined in the Registration Rights Agreement) 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 necessary to make the statements
therein not misleading and will reimburse each Purchaser for any legal or other
expenses reasonably incurred by such Purchaser 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 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 any Preliminary Offering Circular or the Offering Circular or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by any Purchaser through the Representative
expressly for use therein.

                  (b) Each Purchaser will indemnify and hold harmless the
Company against any losses, claims, damages or liabilities to which the Company
may become subject, under the 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


                                       17
<Page>

in any Preliminary Offering Circular or the Offering Circular, 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 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 any Preliminary Offering Circular or Offering Circular or
any such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Purchaser through the
Representative expressly for use therein; and will 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.

                  (c) Promptly after receipt by an indemnified party under
subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be made against
the indemnifying party under such subsection, notify the indemnifying party
in writing of the commencement thereof; 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 such subsection. In case any
such action shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the 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 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, the indemnifying party shall not be liable to such indemnified party
under such subsection 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.

                  (d) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above 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 benefits received by the Company on the one hand and the Purchasers
on the other from the offering of the Securities. If, however, the allocation
provided by the immediately preceding sentence is not permitted by applicable
law or if the indemnified party failed to give the notice required under
subsection (c) above, then each indemnifying party shall contribute to such
amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Purchasers on the other 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 benefits received by the
Company on the one hand and the Purchasers on the other shall be deemed to be in
the same proportion as the total net


                                       18
<Page>

proceeds from the offering (before deducting expenses) received by the Company
bear to the total underwriting discounts and commissions received by the
Purchasers, in each case as set forth in the Offering Circular. The relative
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or the Purchasers on the other and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Purchasers agree that it would not be
just and equitable if contribution pursuant to this subsection (d) were
determined by PRO RATA allocation (even if the Purchasers 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 above in this
subsection (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 in this subsection (d) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), no Purchaser shall be required to contribute
any amount in excess of the amount by which the total price at which the
Securities underwritten by it and distributed to investors were offered to
investors exceeds the amount of any damages which such Purchaser has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. The Purchasers' obligations in this subsection (d)
to contribute are several in proportion to their respective underwriting
obligations and not joint.

                  (e) The obligations of the Company under this Section 8 shall
be in addition to any liability which the Company may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who controls
any Purchaser within the meaning of the Act; and the obligations of the
Purchasers under this Section 8 shall be in addition to any liability which the
respective Purchasers may otherwise have and shall extend, upon the same terms
and conditions, to each person, if any, who controls the Company within the
meaning of the Act.

         9.       (a) If any Purchaser shall default in its obligation to
purchase the Securities which it has agreed to purchase hereunder, you may in
your discretion arrange for you or another party or other parties to purchase
such Securities on the terms contained herein. If within thirty-six hours
after such default by any Purchaser you do not arrange for the purchase of
such Securities, then the Company shall be entitled to a further period of
thirty-six hours within which to procure another party or other parties
satisfactory to you to purchase such Securities on such terms. In the event
that, within the respective prescribed periods, you notify the Company that
you have so arranged for the purchase of such Securities, or the Company
notifies you that it has so arranged for the purchase of such Securities, you
or the Company shall have the right to postpone the Time of Delivery for a
period of not more than seven days, in order to effect whatever changes may
thereby be made necessary in the Offering Circular, or in any other documents
or arrangements, and the Company agrees to prepare promptly any amendments to
the Offering Circular which in your opinion may thereby be made necessary.
The term "PURCHASER" as used in this Agreement shall include any person
substituted under this Section with like effect as if such person had
originally been a party to this Agreement with respect to such Securities.

                  (b) If, after giving effect to any arrangements for the
purchase of the Securities of a defaulting Purchaser or Purchasers by you and
the Company as provided in subsection (a) above, the aggregate principal amount
of such Securities which remains unpurchased does not exceed one-eleventh of the
aggregate principal amount of all the Securities, then the Company shall have
the


                                       19
<Page>

right to require each non-defaulting Purchaser to purchase the principal amount
of Securities which such Purchaser agreed to purchase hereunder and, in
addition, to require each non-defaulting Purchaser to purchase its pro rata
share (based on the principal amount of Securities which such Purchaser agreed
to purchase hereunder) of the Securities of such defaulting Purchaser or
Purchasers for which such arrangements have not been made; but nothing herein
shall relieve a defaulting Purchaser from liability for its default.

                  (c) If, after giving effect to any arrangements for the
purchase of the Securities of a defaulting Purchaser or Purchasers by you and
the Company as provided in subsection (a) above, the aggregate principal amount
of Securities which remains unpurchased exceeds one-eleventh of the aggregate
principal amount of all the Securities, or if the Company shall not exercise the
right described in subsection (b) above to require non-defaulting Purchasers to
purchase Securities of a defaulting Purchaser or Purchasers, then this Agreement
shall thereupon terminate, without liability on the part of any non-defaulting
Purchaser or the Company, except for the expenses to be borne by the Company and
the Purchasers as provided in Section 6 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Purchaser from liability for its default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Purchasers, as set forth in
this Agreement or made by or on behalf of them, respectively, pursuant to this
Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Purchaser or any controlling person of any Purchaser, or the Company, or
controlling person of the Company, and shall survive delivery of and payment for
the Securities.

         11. If this Agreement shall be terminated pursuant to Section 9 hereof,
the Company shall not then be under any liability to any Purchaser except as
provided in Sections 6 and 8 hereof; but, if for any other reason, the
Securities are not delivered by or on behalf of the Company as provided herein,
the Company will reimburse the Purchasers through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Purchasers in making preparations for the
purchase, sale and delivery of the Securities, but the Company shall then be
under no further liability to any Purchaser except as provided in Sections 6 and
8 hereof.

         12. In all dealings hereunder, you shall act on behalf of each of the
Purchasers, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Purchaser made or given
by you jointly or by Goldman Sachs International on behalf of you as the
representative.

         All statements, requests, notices and agreements hereunder shall be
in writing, and if to the Purchasers shall be delivered or sent by mail,
telex or facsimile transmission to you as the representative at Goldman Sachs
International, Peterborough Court, 133 Fleet Street, London EC4A 2BB,
Attention: General Counsel; telephone 0207 774 1000, telex 887902; and if to
the Company shall be delivered or sent by mail, telex or facsimile
transmission to the address of the Company set forth in the Offering
Circular, Attention: Chief Financial Officer; PROVIDED, HOWEVER, that any
notice to a Purchaser pursuant to Section 8(c) hereof shall be delivered or
sent by mail, telex or facsimile transmission to such Purchaser at its
address set forth in its Purchasers' Questionnaire, or telex

                                       20
<Page>

constituting such Questionnaire, which address will be supplied to the Company
by you upon request. Any such statements, requests, notices or agreements shall
take effect upon receipt thereof.

         13. This Agreement shall be binding upon, and inure solely to the
benefit of, the Purchasers, the Company and, to the extent provided in Sections
8 and 10 hereof, each person who controls the Company or any Purchaser, and
their respective heirs, executors, administrators, successors and assigns, and
no other person shall acquire or have any right under or by virtue of this
Agreement. No purchaser of any of the Securities from any Purchaser shall be
deemed a successor or assign by reason merely of such purchase.

         14. The Company irrevocably (i) agrees that any legal suit, action
or proceeding against the Company brought by any Purchaser or by any person
who controls any Purchaser arising out of or based upon this Agreement or the
transactions contemplated hereby may be instituted in any New York Court,
(ii) waives, to the fullest extent it may effectively do so, any objection
which it may now or hereafter have to the laying of venue of any such
proceeding and (iii) submits to the exclusive jurisdiction of such courts in
any such suit, action or proceeding. The Company irrevocably waives any
immunity to jurisdiction to which it may otherwise be entitled or become
entitled (including sovereign immunity, immunity to pre-judgment attachment,
post-judgment attachment and execution) in any legal suit, action or
proceeding against it arising out of or based on this Agreement or the
transactions contemplated hereby which is instituted in any New York Court or
in any competent court in Germany. The Company has appointed CT Corporation
