4.    PAYING AGENCY

and principal of the Notes to the Fiscal Agent, in Euros in same-day funds, to
such account at the Fiscal Agent in London as the Fiscal Agent may from time to
time specify (the "REDEMPTION ACCOUNT") on the Business Day such payment is due,
provided always that, if any due date shall not be a Business Day, the Issuer
shall make such transfer to the account of the Fiscal Agent on the next
succeeding Business Day (for the purposes of this Clause 4, Business Day shall
mean (x) a day on which commercial banks and foreign exchange markets settle
payments and are open for general business in each of London and The City of New
York and (y) a day which is a TARGET business day).

The Issuer hereby authorizes and directs the Fiscal Agent, from the amounts so
paid to it, to make payment of the principal of, and interest on, the Notes on
the due date for payment set forth in the Conditions and this Agreement. If
applicable, the Fiscal Agent will, from funds so received from the Issuer,
credit to the account of the Paying Agent the amounts of all such payments made
by it in accordance with the provisions of this Agreement.

The Issuer shall confirm to the Fiscal Agent not later than 10:00 a.m. (London
time) on the second Business Day before the relevant date for such payment that
it has issued irrevocable payment instructions for such payment to be made.

4.2 If for any reason the Fiscal Agent does not receive unconditionally the full
amount payable by the Issuer on the relevant due date in respect of all the
outstanding or maturing Notes, the Fiscal Agent

<PAGE>
                                       4

shall forthwith notify immediately the Issuer by telephone followed by facsimile
and the Fiscal Agent shall not be bound to make any payment of principal or
interest in respect of the Notes until the Fiscal Agent has received to its
order the full amount of the monies then due and payable in respect of all
outstanding or maturing Notes, provided, however, that if the Fiscal Agent
shall, in its discretion, make any payment of principal or interest on or after
the due date therefor in respect of the Notes prior to its unconditional receipt
of the full amount then due and payable in respect of all outstanding Notes, the
Issuer will promptly pay such amount to the Fiscal Agent and will compensate the
Fiscal Agent at a rate equal to the Fiscal Agent's cost of funding.

4.3 Out of the sums paid to the Fiscal Agent in respect of interest and
principal on the Notes, the Fiscal Agent will make payment free of charge to the
registered holder of the International Global Note and the DTC Global Note as
stipulated in Clause 9 below, in the amounts specified in the Conditions. The
Fiscal Agent shall obtain from the Registrar, and the Registrar shall supply,
such details as are required for the Paying Agent to make payment as stated
above.

4.4 In respect of the monies paid to it relating to any Note, the Fiscal Agent

      4.4.1 shall not be entitled to exercise any lien, right of set-off or
      similar claim (including without limitation any claim arising from or
      relating to any other issue of securities by the Issuer),

      4.4.2 shall not be required to account for interest thereon and

      4.4.3 money held by it need not be segregated except as may be required by
      applicable law.

5.    DOCUMENTS FOR INSPECTION AND PUBLICATION OF NOTICES

5.1 On behalf and at the request and expense of the Issuer, the Fiscal Agent
shall cause to be published any notices required to be given by the Issuer in
accordance with the Conditions.

5.2 The Issuer shall provide to the Fiscal Agent sufficient copies of all
documents required by the Conditions to be available for issue or inspection,
and the Fiscal Agent shall make such copies available to Noteholders upon their
request.

5.3 To the extent practicable, the Issuer shall provide the Fiscal Agent with a
copy (prior to publication) of all notices to be issued in connection with the
Notes.

6.    CANCELLATION OF THE GLOBAL NOTES

6.1 Subject to the terms of the Indenture, promptly upon the Issuer's request,
the Registrar shall take all measures necessary to cancel any Notes which the
Issuer has repurchased or whose maturity has been accelerated pursuant to the
Conditions. The Registrar shall cause any such Notes (i) to the extent
represented by the International Global Note, to be cancelled resulting in a
reduction in the aggregate amount of the Notes represented by the International
Global Note by the aggregate amount of Notes so cancelled, and (ii) to the
extent represented by the DTC Global Note, to be cancelled in accordance with
the procedures established for that purpose by DTC, resulting in a reduction in
the aggregate amount of the Notes represented by the DTC Global Note by the
aggregate amount of the Notes so cancelled.

6.2 On the same day such cancellation is effected, the Registrar shall record
such cancellation of Notes on the Register in such a way that the aggregate
principal amount of Notes cancelled at any time together with the aggregate
principal amount of Notes outstanding and represented by the Global Notes shall
equal the aggregate principal amount of Notes originally issued by the Issuer.

6.3 The Registrar shall upon request furnish the Issuer with a notice of
cancellation signed by an authorized officer of the Registrar confirming the
cancellation of such Notes and the corresponding reduction of the relevant
Global Note(s).

7.    DUTIES OF THE REGISTRAR

7.1 The Registrar shall maintain the Register in London in accordance with the
Conditions. The Register shall show the aggregate amount of Notes represented by
each Global Note at the date of issue and all subsequent transfers and exchanges
involving a change in such amounts and the names and addresses of the registered
holders (each a "PAYEE"). On the first Business Day after the Record Date for
any interest payment on the Notes, the Registrar shall send payment details in
respect of the Payees and the Euros accounts to which transfers should be made
to the Fiscal Agent.

7.2 Transfers or exchanges of Notes will be made in accordance with the
Conditions, the procedures established for this purpose between Euroclear,
Clearstream, DTC and the Registrar, and Euroclear, Clearstream and DTC's
regulations applicable to such transfers or exchanges. Any such transfer or
exchange which results in a change in the aggregate principal amount of Notes
held by Euroclear, Clearstream and DTC shall be notified by Euroclear,
Clearstream and DTC to the Registrar. The Registrar shall promptly enter details
of the transfer or exchange in the Register, which entry shall, without further
action, cause the aggregate principal amount represented by each Global Note to
be amended accordingly.

7.3 The Registrar shall at all reasonable times during office hours make the
Register available to the Issuer and the Fiscal Agent or any person authorised
by either of them for inspection and for the taking of copies thereof or
extracts therefrom, and the Registrar shall deliver to such persons such
information contained in the Register or relating to the Notes as they may
reasonably request.

8.    DUTIES OF THE TRANSFER AGENT

If and to the extent so specified by the Conditions and in accordance therewith,
or if otherwise requested by the Issuer, the Transfer Agent shall make available
all relevant forms of transfer, inform the Registrar of the name and address of
the relevant person to be inserted in the Register and carry out such other acts
as may be necessary to give effect to the Conditions and this Agreement.

9.    PAYMENTS TO DTC NOTEHOLDERS

9.1 All amounts of principal and interest due in respect of the Notes which are
represented by the DTC Global Note (each a "DTC AMOUNT") shall be paid in U.S.
dollars (each such payment being referred to herein as a "U.S. DOLLAR PAYMENT"),
unless DTC has advised the Fiscal Agent that the relevant Noteholder has made an
effective election to receive all or a portion of its payment in Euros outside
DTC (each a "EUROS PAYMENT").

9.2 The Paying Agent shall, from each DTC Amount received by it, make U.S.
Dollar Payments in accordance with the Conditions and Euros Payments in
accordance with the Conditions.

10.   DUTIES OF EXCHANGE AGENT

      The Exchange Agent shall:

(i)   accept Euros by remittance to an account maintained by the Exchange Agent
      of the total amount of interest or principal due on any payment date on
      Notes held by Cede & Co. (as nominee of DTC) on the Record Date. The
      Exchange Agent shall be advised by Cede & Co. (as nominee of DTC) if any
      beneficial holders of the Notes held by Cede & Co. (as nominee of DTC)
      have elected to receive payment in Euros and, if so, the amount of Notes
      held by such holders and the accounts to which such payments in Euros are
      to be wired. On the payment date, the Exchange Agent shall wire payment in
      the appropriate Euro amounts to the accounts indicated. The remainder on
      such payment date shall be exchanged by the Exchange Agent pursuant to
      sub-clause (ii) below into U.S. dollars and, after deduction of any costs
      relating to such exchange, shall be paid to Cede & Co. (as nominee of DTC)
      on the payment date; and

(ii)  at or prior to 11:00 a.m., London time, on the second London business day
      preceding the applicable payment date, enter into a contract for the
      purchase of U.S. dollars with the Specified Amount of Euros for settlement
      on such payment date. "SPECIFIED AMOUNT" shall

<PAGE>
                                       6

      mean the aggregate amount of Euros payable to all Noteholders holding
      Notes through participants of DTC that have not elected to receive
      payments in Euros. The amount of U.S. dollars payable in respect of a
      particular payment under the DTC Global Note will be equal to the amount
      of Euros otherwise payable exchanged into U.S. dollars at the Euro/U.S.$
      exchange rate prevailing as at 11:00 a.m. (London time) on the second
      London business day prior to the relevant payment date, less any costs
      incurred by the Exchange Agent for such conversion (such costs to be
      shared pro rata among holders under the DTC Global Note accepting U.S.
      dollar payments in proportion of their respective holdings). If an
      exchange rate bid quotation is not so available, the Exchange Agent shall
      obtain a bid quotation from a leading foreign exchange bank in London
      selected by the Exchange Agent after consultation with the Issuer. If no
      bid quotation is so available, payment will be made in Euros to the
      account or accounts specified by DTC to the Exchange Agent. Pending
      specification of such account or accounts, funds held by the Exchange
      Agent shall bear interest at the rate quoted by it for deposits with the
      Exchange Agent on an overnight basis, but only to the extent that the
      Exchange Agent is able to reinvest such funds. If the payment date is not
      a day on which commercial banks are open for business (including dealings
      in foreign currencies) in each of London and New York City, delivery of
      the U.S. dollars will occur on the next succeeding day which is such a
      business day. In this sub-clause (ii), the term "London business day"
      shall mean any day on which commercial banks and foreign exchange markets
      settle payments in New York City and London.

11.   CONDITIONS OF APPOINTMENT

11.1 The Issuer will pay to the Agents a remuneration for all services rendered
hereunder by the Agents in connection with the Notes together with any expenses
incurred as separately agreed upon by the Agents and the Issuer.

11.2 The Issuer will indemnify and hold harmless each of the Agents against any
loss, liability or expense which it may incur or any claim, action or demand

connection with such Agent's appointment or the exercise of its powers and
duties hereunder without negligence or wilful misconduct on the part of such
Agent.

11.3 Each Agent will indemnify and hold harmless the Issuer against any loss,

agents) and arising out of or in connection with such Agent's duties hereunder.
Notwithstanding the foregoing, under no circumstances will any Agent be liable

Agreement.

11.5 Each of the Agents shall be protected and shall incur no liability for or

party or parties in accordance with the provisions hereof, except such as may
result from its own negligence or wilful misconduct or that of its officers,
employees or agents.

11.6 In acting hereunder and in connection with the Notes, the Agents do not
assume any relationship of agency and trust for the Noteholders, and shall not
have any obligation towards them except that all funds held by the Fiscal Agent

set forth herein and in the Conditions. Except as otherwise required by

funds in the performance of its duties hereunder.

<PAGE>
                                       7

hereunder in good faith and without negligence and in accordance with the
opinion of such advisers.

obligation to take any action hereunder which it expects will result in any
expense or liability of such Agent, the payment of which within a reasonable
time is not, in its opinion, assured to it. The obligations of the Agents
hereunder are several and not joint.

11.10 The Agents, their affiliates and their respective officers and employees,

been appointed by the Issuer as hereinafter provided, and such new Agent shall
have accepted such appointment. Any change in any Agent shall be notified by the
Issuer to the other Agent(s).

affiliates and their respective employees and agents, substantially in the form
set forth in Appendix A. The Severance Benefit shall be paid by the Company in a
lump-sum, no later than two (2) business days after the expiration of the

employment under the provision so indicated.

breaches any of the provisions of Sections 5.01, 5.02, 5.03 and/or 5.05 below,

            5. RESTRICTIVE COVENANTS.

            5.01 CONFIDENTIALITY; NONDISCLOSURE. Executive understands and
acknowledges that in the course of Executive's employment, he has had and will
continue to have access to and will learn information proprietary to the Company
and its subsidiaries affiliates (the "COMPANY GROUP") that concerns the

including, without limitation, business plans, financial information, protocols,
proposals, manuals, procedures and guidelines, computer source codes, programs,
software, know-how and specifications, copyrights, trade secrets, market
information, Developments (as hereinafter defined), data and customer
information (collectively, "PROPRIETARY INFORMATION"). Executive agrees that
during the period beginning on the date of his hiring and continuing in
perpetuity thereafter, Executive shall keep confidential and shall not disclose
any such Proprietary Information to any third party, except as required to
fulfill his duties in connection with his employment by the Company, and shall
not misuse, misappropriate or exploit such Proprietary Information in any way.
The restrictions contained herein shall not apply to any information which
Executive can demonstrate (i) was already available to the public at the time of
disclosure, or subsequently became available to the public, otherwise than by
breach of this Agreement or (ii) was the subject of a court order to disclose.
Upon any termination of Executive's employment, Executive will immediately
return to the Company all Proprietary Information and copies thereof in
Executive's possession.

            "DEVELOPMENTS" shall mean all data, discoveries, findings, reports,
designs, inventions, improvements, methods, practices, techniques, developments,
programs, concepts and ideas, whether or not patentable, relating to the present
or planned activities, or the products and services of the Company.

            5.02 NO COMPETING EMPLOYMENT. Executive hereby acknowledges that in
the course of Executive's employment with the Company, Executive has become
familiar, and will become familiar, with the trade secrets of the Company Group
and with other confidential information concerning the Company Group, and that
Executive's services have been and will be of special, unique and extraordinary
value to the Company Group. Therefore, Executive hereby agrees that for the
duration of the Restricted Period, Executive shall not, unless Executive
receives the prior written consent of the Board of Directors of the Company (the
"BOARD"), directly or indirectly, knowingly own an interest in, manage, operate,
join, control, lend money or render financial or other assistance to or
participate in or be connected with, as an officer, employee, partner,
stockholder, consultant or otherwise, any individual, partnership, firm,
corporation or other business organization or entity that competes with the
business of the Company as such businesses exist or are in the process of being
formed or acquired as of the Termination Date, within any geographical area in
which the Company is engaged, services customers, or was actively planning to
engage during the Term or as of the Termination Date; provided, however, that
this Section 5.02 shall not proscribe Executive's ownership, either directly or
indirectly, of less than one percent of any class of securities which are listed
on a national securities exchange or quoted on the automated quotation system of
the National Association of Securities Dealers, Inc.

                                       4
<PAGE>
            5.03 RESTRICTIONS ON SOLICITATION. During the Restricted Period and
except as required pursuant to Executive's duties to the Company in connection
with the employment relationship, Executive will not, directly or indirectly:
(i) solicit or contact any customer of the Company Group (or any other entity
that Executive knows is a potential customer with respect to specific products
of the Company Group and with which Executive have had contact during the period
of Executive's employment with the Company Group) for any commercial pursuit
that to Executive's knowledge is in competition with the Company, or that to
Executive's knowledge is contemplated from time to time during the period of
Executive's employment with the Company by the Company's business plan; (ii)
take away or interfere or attempt to interfere with any custom, trade, business,
patronage or other business relation of the Company, or induce, or attempt to
induce, any employees, agents or consultants of or to the Company Group to do
anything from which Executive is restricted by reason of this Section 5; or
(iii) induce or aid others to induce employees, agents or consultants of the
Company Group to terminate their employment with the Company Group, or interfere
or attempt to interfere with any employees, agents or consultants of the Company
Group.

            5.04 EXTENSION OF RESTRICTED PERIOD. The Restricted Period shall be
extended by the length of any period during which Executive is in breach of any
of the terms of Section 5 hereof.

            5.05 ASSIGNMENT OF DEVELOPMENTS. During the Term, all Developments
that are at any time made, conceived or suggested by Executive, whether acting
alone or in conjunction with others, shall be the sole and absolute property of
the Company, free of any reserved or other rights of any kind on Executive's
part. During the Term, if such Developments were made, conceived or suggested by
Executive during or as a result of Executive's employment relationship with the
Company, thereafter, Executive shall promptly make full disclosure of any such
Developments to the Company and, at the Company's cost and expense, do all acts
and things (including, among others, the execution and delivery under oath of
patent and copyright applications and instruments of assignment) deemed by the
Company to be necessary or desirable at any time in order to effect the full
assignment to the Company, or of Executive's right and title, if any, to such
Developments. Executive acknowledges and agrees that any invention, concept,
design or discovery that concretely relates to or is associated with Executive's
work for the Company that is described in a patent application or is disclosed
to a third party directly or indirectly by Executive during the Restricted
Period shall be the property of and owned by the Company and such disclosure by
patent application or otherwise shall constitute a breach of Section 5.01 above.

            5.06 APPLICATION OF COVENANTS. The activities described in this
Section 5 shall be prohibited regardless of whether undertaken by Executive in
an individual or representative capacity, and regardless of whether performed
for Executive's own account or for the account of any other individual,
partnership, firm, corporation or other business organization (other than the
Company Group).

            5.07 INJUNCTIVE RELIEF. Without limiting the remedies available to
the Company, Executive acknowledges that a breach of any of the covenants
contained in this

                                       5
<PAGE>
Section 5 may result in material irreparable injury to the Company 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 such a breach or
threat thereof, the Company shall be entitled to seek a temporary restraining
order or a preliminary or permanent injunction restraining Executive from
engaging in activities prohibited by this Section 5 or such other relief as may
be required to specifically enforce any of the covenants in this Section 5.

            5.08 REASONABLENESS OF COVENANTS. If, at the time of enforcement of
the covenants set forth in this Section 5, a court holds that the restrictions
stated herein are unreasonable under circumstances then existing, the parties
hereto agree that the maximum period, scope or geographical area reasonable
under such circumstances shall be substituted for the stated period, scope or
area.

            5.09 VIOLATION AND REMEDY. If the Company reasonably determines that
Executive has breached any of the provisions of this Section 5, in addition to
any other remedies available to the Company in law or equity, the Company shall
be entitled to immediately suspend as of the date of such breach the provision
to Executive of any payments or benefits under this Agreement, including without
limitation, the Severance Benefit outlined in Section 4 of this Agreement, and
any Severance Benefits already paid shall be immediately returned to the
Company. In addition, should the Company breach any of its obligations under
this Agreement, including without limitation, the Severance Benefit outlined in
Section 4, Executive will not be bound by the provisions of Sections 5.02 and
5.03.

            9. MISCELLANEOUS.

            9.01 NO RIGHTS TO CONTINUED EMPLOYMENT. Neither this Agreement nor
any of the rights or benefits evidenced hereby shall confer upon Executive any
right to continuance of employment by the Company or interfere in any way with
the right of the Company to terminate Executive's employment, subject to the
provisions of Section 4 above, for any reason, with or without Cause.

            9.02 EXECUTIVE'S REPRESENTATION. Executive hereby represents and
warrants to the Company that the execution and delivery by Executive of this
Agreement to the Company will not breach the terms of any contract, agreement or
understanding to which Executive is party. Executive further acknowledges and
agrees that a breach of this representation by Executive shall render this
Agreement void ab initio and of no further force and effect.

            9.03 SUCCESSORS. This Agreement shall be binding upon and inure to
the benefit of and be enforceable by the parties hereto and their respective
heirs, legal representatives, successors and, in the case of the Company,

rights under or by virtue of this Agreement, and the obligations of Executive
under this Agreement may not be assigned or delegated.

            9.04 SEVERABILITY. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under

illegal or unenforceable in any respect under any applicable law or rule in any

any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision had never been contained herein.

counterparts, each of which is deemed to be an original and all of which taken
together constitute one and the same agreement.

            9.09 GOVERNING LAW. This Agreement shall be governed by and
construed and enforced in accordance with the laws and decisions of the State of
New York applicable to contracts made and to be performed therein without giving
effect to the principles of conflict of laws.

            9.10 ENTIRE AGREEMENT; MODIFICATION; WAIVER; INTERPRETATION. This
Agreement contains the entire agreement and understanding between the parties
with respect to the subject matter hereof and supersedes all prior negotiations
and oral understandings concerning the subject matter hereof; provided, however,

Appendix C and incorporated herein by reference, and (2) Section 2 (entitled
"Retention Bonus") of the Retention and Severance Agreement dated October 11,
2001, attached hereto as Appendix D and incorporated herein by reference, shall
be enforceable and binding on the parties. This Agreement supercedes the
remaining terms and conditions of said Retention and Severance Agreement;
provided, however, that it is the intention of the parties hereto that if this
Agreement is void, becomes voidable, or otherwise is or becomes unenforceable as
drafted, then the Retention and Severance Agreement shall continue in full force
and effect, in accordance with the terms and conditions thereof immediately
prior to the execution of this Agreement. Neither this Agreement nor any of its
provisions may be modified, amended, waived, discharged or terminated, in whole
or in part, except in writing signed by the party to be charged. No waiver of
any such provision or any breach of or default under this Agreement shall be
deemed or shall constitute a waiver of any other provision, breach or default.
All pronouns and words used in this Agreement shall be read in the appropriate
number and gender, the masculine, feminine and neuter shall be interpreted
interchangeably and the singular shall include the plural and vice versa, as the
circumstances may require.
