                        (ii) the preparation and filing by the Trust with the

company" required to be registered under the 1940 Act, or taxed as a corporation
for United States Federal or German income tax purposes or for purposes of any
income tax imposed by the jurisdiction of formation of the Issuer and so that
the Notes will be treated as indebtedness of the Issuer and the Sponsor for
United States Federal or German income tax purposes and for purposes of any
income tax imposed by the jurisdiction of formation of the Issuer. In this
connection, the Sponsor and the Company Trustees are authorized to take any
action, not inconsistent with applicable law, the Certificate of Trust or this
Declaration, that each of the Sponsor and the Company Trustees determines in

action does not adversely affect in any material respect the interests of the
Holders of Preferred Securities.

establish the Payment Account. The Preferred Trustee and any agent of the
Preferred Trustee shall have exclusive control and sole right of withdrawal with
respect to the Payment Account for the purpose of making withdrawals from the

                                       16
<PAGE>   23

Declaration. All monies and other property deposited or held from time to time
in the Payment Account shall be held by the Preferred Trustee in the Payment
Account for the exclusive benefit of the Securityholders and for distribution as
herein provided, including (and subject to) any priority of payments provided
for herein.

                (B) The Preferred Trustee shall deposit in the Payment Account,
promptly upon receipt, all payments of principal of or interest on, and any
other payments or proceeds with respect to, the Notes. Amounts held in the

                                   ARTICLE IV
                            DISTRIBUTIONS; REDEMPTION

                .1 Distributions.

                (A) Distributions on the Trust Securities shall be cumulative,
and will accumulate whether or not there are funds of the Trust available for
the payment of Distributions. Distributions shall accrue from the date of
issuance of the Preferred Securities, and shall be payable quarterly in arrears
on March 15, June 15, September 15 and December 15 of each year, commencing on
September 15, 2001. If any date on which a Distribution is otherwise payable on
the Trust Securities is not a Business Day, then the payment of such
Distribution shall be made on the next succeeding day that is a Business Day
(and without any interest or other payment in respect of any such delay) except
that, if such Business Day is in the next succeeding calendar year, payment of
such Distribution shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date (each date on
which distributions are payable in accordance with this Section 4.1(a), a
"Distribution Date").

                (B) The Trust Securities represent undivided beneficial
interests in the Trust Property. Distributions on the Trust Securities shall be
payable at a rate of 7.875% per annum of the Liquidation Amount of the Trust
Securities. Distributions in arrears for more than one quarter (and interest
thereon) will accrue interest (compounded quarterly) at the same rate. The
amount of Distributions payable for any full period shall be computed on the
basis of a 360-day year of twelve 30-day months. The amount of Distributions for
any partial period shall be computed on the basis of the number of days elapsed
in a 360-day year of twelve 30-day months. The amount of Distributions payable
for any period shall include the Additional Payments and the Additional Amounts,
if any, for such period.

                (C) Distributions on the Trust Securities shall be made by the
Preferred Trustee from the Payment Account and shall be payable on each
Distribution Date only to the extent that the Trust has funds then legally
available in the Payment Account for the payment of such Distributions.

                (D) Distributions on the Trust Securities with respect to a
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Securities at the close of business on the
relevant record date, which shall be 15 days prior to such Distribution Date.

                .2 Redemption.


                                       17
<PAGE>   24

                (A) On each Note Redemption Date and on the stated maturity of
the Notes, the Trust will be required to redeem a Like Amount of Trust
Securities at the Redemption Price. The Trust Securities shall not be redeemed
unless all accrued and unpaid Distributions have been paid on all Trust
Securities for all quarterly distribution periods terminating on or prior to the
Redemption Date.

                (B) Notice of redemption shall be given by the Preferred Trustee
by first-class mail, postage prepaid, mailed not less than 30 nor more than 60
days prior to the Redemption Date to each Holder of Trust Securities to be
redeemed, at such Holder's address appearing in the Security Register. All
notices of redemption shall be irrevocable and shall state:

                        (i) the Redemption Date;

                        (ii) the Redemption Price;

                        (iii) the CUSIP number;

                        (iv) if less than all the Outstanding Trust Securities
are to be redeemed, the identification and the total Liquidation Amount of the
particular Trust Securities to be redeemed; and

                        (v) that on the Redemption Date the Redemption Price
will become due and payable upon each such Trust Security to be redeemed and
that distributions thereon will cease to accrue on and after said date; and

                        (vi) the place or places where the Trust Securities are
to be surrendered for the payment of the Redemption Price.

                (C) The Trust Securities redeemed on each Redemption Date shall
be redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Notes. Redemptions of the Trust Securities shall be made and the
Redemption Price shall be payable on each Redemption Date only to the extent
that the Trust has funds then legally available in the Payment Account for the
payment of such Redemption Price.

                (D) If the Preferred Trustee gives a notice of redemption in
respect of any Preferred Securities, then, by 12:00 noon, New York City time, on
the Redemption Date, subject to Section 4.2(c), the Preferred Trustee will, so
long as the Preferred Securities are in book-entry-only form, in its capacity as
Paying Agent, irrevocably deposit with the Paying Agent for such Preferred
Securities, to the extent available therefor, funds sufficient to pay the
applicable Redemption Price and will give such Paying Agent (if other than the
Preferred Trustee) irrevocable instructions and authority to pay the Redemption
Price to the holders thereof. If the Preferred Securities are no longer in
book-entry-only form, the Preferred Trustee, subject to Section 4.2(c), will
irrevocably deposit with the Paying Agent, to the extent available therefor,
funds sufficient to pay the applicable Redemption Price and will give the Paying
Agent irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof upon surrender of their Preferred Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Register for the
Trust Securities on the relevant record dates for the related


                                       18
<PAGE>   25

Distribution Dates. If notice of redemption shall have been given and funds
deposited as required, then upon the date of such deposit, all rights of
Securityholders holding Trust Securities so called for redemption will cease,
except the right of such Securityholders to receive the Redemption Price and any
Distribution payable on or prior to the Redemption Date, but without interest,
and such Securities will cease to be Outstanding. In the event that any date on
which any Redemption Price is payable is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), except that, if such Business Day falls in the next calendar
year, such payment will be made on the immediately preceding Business Day, in
each case, with the same force and effect as if made on such date. In the event
that payment of the Redemption Price in respect of any Trust Securities called
for redemption is improperly withheld or refused and not paid either by the
Trust or by the Sponsor pursuant to the Trust Guarantee, Distributions on such
Trust Securities will continue to accrue, at the then applicable rate, from the
Redemption Date originally established by the Trust for such Trust Securities to
the date such Redemption Price is actually paid, in which case the actual
payment date will be the date fixed for redemption for purposes of calculating
the Redemption Price (other than for purposes of calculating any premium).

                (E) Payment of the Redemption Price on the Trust Securities
shall be made to the record holders thereof as they appear on the Securities
Register for the Trust Securities at the close of business on the relevant
record date, which shall be 15 days prior to the relevant Redemption Date. In
the event that any date on which payment of the Redemption Price on the
Preferred Securities is not a Business Day, payment of the Redemption Price on
such date will be made on the next succeeding day which is a Business Day
(without any distribution or other payment in respect of any such delay) except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on such date.

                (F) Subject to the foregoing and applicable law (including,
without limitation, United States Federal securities laws), the Sponsor or its
subsidiaries may at any time and from time to time purchase Outstanding
Preferred Securities by tender, in the open market or by private agreement.

                .3 Subordination of Common Securities.

                Payment of Distributions (including Additional Payments and
Additional Amounts if applicable) on, and the Redemption Price of, the Trust
Securities, as applicable, shall be made pro rata among the Common Securities
and the Preferred Securities based on the respective Liquidation Amounts of the
Trust Securities; provided, however, that if on any Distribution Date or
Redemption Date a Declaration Event of Default shall have occurred and be
continuing, no payment of any Distribution (including Additional Payments and
Additional Amounts, if applicable) on, or Redemption Price of, any Common
Security, and no other payment on account of the redemption, liquidation or
other acquisition of Common Securities, shall be made unless payment in full in
cash of all accumulated and unpaid Distributions (including Additional Payments
and Additional Amounts, if applicable) on all Outstanding Preferred Securities
for all Distribution periods terminating on or prior thereto, or in the case of
payment of the Redemption Price the full amount of such Redemption Price on all


                                       19
<PAGE>   26

Outstanding Preferred Securities, shall have been made or provided for, and all
funds immediately available to the Preferred Trustee shall first be applied to
the payment in full in cash of all Distributions (including Additional Payments
and Additional Amounts, if applicable) on, or the Redemption Price of, Preferred
Securities then due and payable.

                .4 Payment Procedures.

                Payments of Distributions (including Additional Payments and
Additional Amounts, if applicable) in respect of the Preferred Securities shall
be made by check mailed to the address of the Person entitled thereto as such
address shall appear on the Securities Register or, if the Preferred Securities
are held by a Clearing Agency, such Distributions shall be made to the Paying
Agent by wire transfer in immediately available funds, which shall credit the
relevant Persons' accounts on the applicable distribution dates. Payments in
respect of the Common Securities shall be made in such manner as shall be
mutually agreed between the Preferred Trustee and the Common Securityholder(s).

                .5 Tax Returns and Reports.

                The Company Trustees shall prepare (or cause to be prepared), at
the Sponsor's expense, and file all United States Federal, state and local tax

Trust. In this regard, the Company Trustees shall (a) prepare and file (or cause
to be prepared and filed) the appropriate Internal Revenue Service Form required

Securityholder the appropriate Internal Revenue Service form required to be

Preferred Trustee with a copy of all such returns and reports promptly after

and information reporting requirements with respect to any payments to
Securityholders under the Trust Securities.

                .6 Payment of Taxes, Duties, Etc. of the Trust.

                Upon receipt under the Notes of Additional Sums or Additional
Amounts and the written direction of the Sponsor, the Preferred Trustee shall
promptly pay any taxes, duties or governmental charges of whatsoever nature
(other than withholding taxes) imposed on the Trust by the United States or any
other taxing authority.

                .7 Payments under Indenture.

                Any amount payable hereunder to any Holder of Preferred
Securities (and any Owner with respect thereto) shall be reduced by the amount
of any corresponding payment such Holder (and Owner) has directly received
pursuant to Section 5.8 of the Indenture.

                .8 Change of Control.

                (A) Upon the occurrence of a Change of Control Triggering Event
(as defined in the Indenture), each Holder shall have the right to require, and

                .9 Offer to Repurchase Upon Asset Disposition.

                If the Issuer makes an offer to repurchase Notes in the event of
an Asset Disposition (as defined in the Indenture) pursuant to Section 10.13 of

Like Amount of Preferred Securities, at a purchase price equal to 100% of the
Liquidation Amount of the Preferred Securities (without premium), plus accrued
and unpaid Distributions thereon to the date of purchase. In the event of any
such offer to purchase Notes pursuant to Section 10.13 of the Indenture, the

forth in Section 4.8 with respect to a Change of Control offer (including
compliance, to the extent applicable, with the requirements of Section 14(e) of
the Exchange Act).

                          Trust Securities Certificates

                .1 Initial Ownership.

                Upon the formation of the Trust and the contribution by the
Sponsor pursuant to Section 2.3 and until the issuance of the Trust Securities,
and at any time during which no Trust Securities are outstanding, the Sponsor
shall be the sole beneficial owner of the Trust.

                .2 The Trust Securities Certificates.

                (A) The Preferred Securities Certificates shall be issued in
minimum denominations of $1,000 Liquidation Amount and integral multiples of
$1,000 in excess thereof, and the Common Securities Certificates shall be issued
in denominations of $1,000 Liquidation Amount and integral multiples thereof.
The Initial Preferred Securities may only be issued and transferred with minimum
liquidation amounts of $100,000 or more. The Trust Securities Certificates shall
be executed on behalf of the Trust by manual or facsimile signature of at least
one Company Trustee (and, in the case of Preferred Securities Certificates,
shall be authenticated by the Preferred Trustee by manually executing a
certificate of authentication substantially in the form appearing in Exhibit E
hereto). Trust Securities Certificates bearing the manual or facsimile
signatures, as the case may be, of individuals who were, at the time when such
signatures shall have been affixed, authorized to sign on behalf of the Trust,
shall be validly issued and entitled to the benefits of this Declaration,
notwithstanding that such individuals or any of them shall have ceased to be so
authorized prior to the delivery of such Trust Securities Certificates or did
not hold such offices at the date of delivery of such Trust Securities
Certificates. A transferee of a Trust Securities Certificate shall become a
Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.11
and 5.13.

                Prior to the issuance of any Exchange Preferred Securities, the
Sponsor shall deliver to the Preferred Trustee an Opinion of Counsel
substantially to the effect that: (i) the Exchange Preferred Securities have
been duly authorized and, when executed and authenticated in accordance with the
provisions of the Declaration and delivered in exchange for the Initial
Preferred Securities in accordance with the Declaration and the Exchange Offer,
will be entitled to the benefits of the Declaration and will be legally valid
and binding obligations of the Trust, enforceable in accordance with their terms
subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors' rights and to general equity principles; and (ii) when the Exchange
Preferred Securities are executed and authenticated in accordance with the
provisions of the Declaration and delivered in exchange for the Initial
Preferred Securities in accordance with the Declaration and the Exchange Offer,
the Exchange Guarantee Agreement relating thereto will be the legally valid and
binding obligation of the Sponsor, enforceable in accordance with its terms
subject to bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium and similar laws of general applicability relating to or affecting
creditors' rights and general equity principles.

                (B) Pending the preparation of definitive Trust Securities
Certificates, at least one Company Trustee, on behalf of the Trust may execute,
(and, in the case of Preferred


                                       22
<PAGE>   29

Securities the Preferred Trustee shall authenticate by manually executing a
certificate of authentication substantially in the form appearing in Exhibit E)
and deliver, temporary Trust Securities Certificates which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Trust Securities
Certificates in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers
executing such Trust Securities Certificates and Guaranties, as the case may be,
may determine, as evidenced by their execution of such Trust Securities
Certificates and Guaranties, as the case may be.

                If temporary Trust Securities Certificates are issued, the
Company Trustees will cause definitive Trust Securities Certificates (which may
be printed, lithographed, typewritten, mimeographed or otherwise produced) to be
prepared without unreasonable delay. After the preparation of definitive Trust
Securities Certificates, the temporary Trust Securities Certificates shall be
exchangeable for definitive Trust Securities Certificates upon surrender of the
temporary Trust Securities Certificates at the office or agency of the Company
Trustees designated for that purpose without charge to the Securityholder. Upon
surrender for cancellation of any one or more temporary Trust Securities
Certificates, at least one Company Trustee, on behalf of the Trust shall execute
(and, in the case of Preferred securities the Preferred Trustee shall
authenticate by manually executing a certificate of authentication substantially
in the form appearing in Exhibit E) and deliver in exchange therefore a like
principal amount of definitive Trust Securities Certificates of authorized
denominations having the same terms and like tenor. Until so exchanged, the
temporary Trust Securities Certificates shall in all respects be entitled to the
same benefits under this Declaration as definitive Trust Securities
Certificates.

                .3 Execution and Delivery of Trust Securities Certificates.

                On the Closing Date, the Company Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5 and as contemplated by Section 5.11, to be executed on
behalf of the Trust and delivered to or upon the written order of the Sponsor,
signed by any member of the Managing Board or without further corporate action
by the Sponsor, in authorized denominations; and, in the case of Preferred
Securities, the Preferred Trustee shall cause such Preferred Securities
Certificates to be authenticated and delivered to or upon the written order of
the Sponsor in authorized denominations.

                .4 Registration of Transfer and Exchange of Preferred Securities
Certificates.

                (A) The Sponsor shall keep or cause to be kept, at the office or
agency maintained pursuant to Section 5.8, a register or registers for the
purpose of registering Trust Securities Certificates and transfers and exchanges
of Preferred Securities Certificates (the "Securities Register") in which the
registrar designated by the Sponsor (the "Securities Registrar"), subject to
such reasonable regulations as it may prescribe, shall provide for the
registration of Preferred Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided. The Bank shall be the initial
Securities Registrar.


                                       23
<PAGE>   30

                (B) Subject to Sections 5.11, 5.13 and 5.4(D) hereof, upon
surrender for registration of transfer of any Preferred Securities Certificate
at the office or agency maintained pursuant to Section 5.8, the Company Trustees
or any one of them shall execute and deliver to the Preferred Trustee, and the
Preferred Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Preferred Securities Certificates in
authorized denominations of a like aggregate Liquidation Amount dated the date
of authentication by such Preferred Trustee and bearing such restrictive legends
as may be required by this Declaration, provided that Initial Preferred
Securities may only be transferred with minimum liquidation amounts of $100,000
or more.

                The Securities Registrar shall not be required to register the
transfer of any Preferred Securities that have been called for redemption. At
the option of a Holder, Preferred Securities Certificates may be exchanged for
other Preferred Securities Certificates in authorized denominations of the same
class and of a like aggregate Liquidation Amount, bearing such restrictive
legends as may be required by this Declaration and bearing a certificate number
not contemporaneously Outstanding, upon surrender of the Preferred Securities
Certificates to be exchanged at the office or agency maintained pursuant to
Section 5.8. Whenever any Preferred Securities Certificates are so surrendered
for exchange, the Company Trustees or any one of them shall execute and deliver
to the Preferred Trustee, and the Preferred Trustee shall authenticate and
deliver, the Preferred Securities Certificates that the Holder making the
exchange is entitled to receive.

                (C) All Preferred Securities issued upon any registration of
transfer or exchange of Preferred Securities shall evidence the same interest in
the assets of the Trust, and be entitled to the same benefits under this
Declaration, as the Preferred Securities surrendered upon such registration of
transfer or exchange.

                (D) The following transfer restrictions shall apply to the
transfer of Initial Preferred Securities:

                        (i) Transfer of beneficial interests in a Restricted
        Book-Entry Preferred Securities Certificate to a Regulation S Book-Entry
        Preferred Securities Certificate. A beneficial interest in a Restricted
        Book-Entry Preferred Securities Certificate may be exchanged for a
        beneficial interest in a Regulation S Book-Entry Preferred Securities
        Certificate only in connection with a pending transfer of such interest
        that complies with Regulation S or Rule 144A under the Securities Act
        and only if a written instrument of transfer duly executed by the Holder
        thereof or his attorney and substantially in the form of Exhibit F-1 is
        first delivered to the Securities Registrar by or on behalf of the
        Person who is the beneficial owner of such interest immediately prior to
        such transfer.

                        (ii) Transfer of beneficial interests in a Regulation S
        Book-Entry Preferred Securities Certificate to a Restricted Book-Entry
        Preferred Securities Certificate. A beneficial interest in a Regulation
        S Book-Entry Preferred Securities Certificate may be exchanged for a
        beneficial interest in a Restricted Book-Entry Preferred Securities
        Certificate only in connection with a pending transfer of such interest
        that complies with Rule 144A under the Securities Act and only if a
        written instrument of transfer duly executed by the Holder thereof or
        his attorney and substantially in the form of Exhibit F-2 and, if the
        Sponsor, so requests, evidence


                                       24
<PAGE>   31

        reasonably satisfactory to them (which shall include an opinion of
        counsel to the Holder) as to the compliance with the restrictions set
        forth in the legend set forth in Section 5.4(G)(i), is first delivered
        to the Securities Registrar by or on behalf of the Person who is the
        beneficial owner of such interest immediately prior to such transfer.

                        (iii) Transfer of beneficial interests in a Temporary
        Regulation S Book-Entry Preferred Securities Certificate to a Permanent
        Regulation S Book-Entry Preferred Securities Certificate. A beneficial
        interest in a Temporary Regulation S Book-Entry Preferred Securities
        Certificate may be exchanged for a beneficial interest in a Permanent
        Regulation S Book-Entry Preferred Securities Certificate only if (a) the
        Distribution Compliance Period has ended and (b) a written certification
        substantially in the form of Exhibit F-3 has been delivered to the
        Securities Registrar by or on behalf of the Person who is the beneficial
        owner of such interest immediately prior to such exchange.
        Notwithstanding any provision of this Declaration, no amount shall be
        paid hereunder (or under the Trust Securities and the Notes) in respect
        of the Temporary Regulation S Book-Entry Preferred Securities
        Certificate or any portion thereof; rather the Paying Agent shall hold
        any such amount that becomes payable pending exchange of such security
        (or portion) for the Permanent Regulation S Book-Entry Preferred
        Securities Certificate (or a portion thereof) and upon such exchange
        shall promptly pay such amount to the Holder of such Permanent
        Regulation S Book-Entry Preferred Securities Certificate. No such
        suspension of payment shall result in a default under the Book-Entry
        Preferred Securities Certificates, if the suspended payment is made
        promptly upon such exchange.

                (E) Every Preferred Securities Certificate presented or
surrendered for registration of transfer or exchange shall be accompanied by a
written instrument of transfer substantially in the form appearing in Exhibit E
(under the heading "Assignment"), duly executed by the Holder or his attorney
duly authorized in writing. Each Preferred Securities Certificate surrendered
for registration of transfer or exchange shall be cancelled and subsequently
disposed of by a Company Trustee in accordance with such Person's customary
practice.

                No service charge shall be made for any registration of transfer
or exchange of Preferred Securities Certificates, but the Securities Registrar
may require payment of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer or exchange of Preferred
Securities Certificates.

                (F) The Preferred Trustee and Securities Registrar shall have no
obligation or duty to monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Declaration or under applicable law
with respect to any transfer of any interest in any Trust Securities Certificate
other than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly
required by, the terms of this Declaration, and to examine the same to determine
substantial compliance as to form with the express requirements hereof.

        the following form:

UNTIL THE PREFERRED SECURITIES ARE REGISTERED PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT FILED UNDER THE SECURITIES ACT, PREFERRED SECURITIES MAY

        representing a Temporary Regulation S Book-Entry Preferred Securities
        Certificate shall bear a legend substantially to the following effect
        (with such changes as may be determined by the Sponsor, based upon

                        (iv) As long as the Preferred Securities are represented
                by Book-Entry Preferred Securities Certificates, such Book-Entry
                Preferred Securities Certificates shall bear a legend

receive evidence to its satisfaction of the destruction, loss or theft of any
Trust Securities Certificate and (b) there shall be delivered to the Securities

the Company Trustees, or any one of them, on behalf of the Trust shall execute
and make available for delivery, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust
Securities Certificate of like class, tenor and denomination. In connection with
the issuance of any new Trust Securities Certificate under this Section, the
Company Trustees or the Securities Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Trust Securities Certificate issued pursuant
to this Section shall constitute conclusive evidence of an undivided beneficial
interest in the assets of the Trust, as if originally issued, whether or not the
lost, stolen or destroyed Trust Securities Certificate shall be found at any
time.

                .6 Persons Deemed Securityholders.

<PAGE>   34

                The Company Trustees or the Securities Registrar shall treat the
Person in whose name any Trust Securities Certificate shall be registered in the
Securities Register as the owner of such Trust Securities Certificate for the
purpose of receiving Distributions and for all other purposes whatsoever, and
neither the Trustees nor the Securities Registrar shall be bound by any notice
to the contrary.

                .7 Access to List of Securityholders' Names and Addresses.

                Each Holder of a Trust Securities Certificate, and each Owner
shall be deemed to have agreed not to hold the Sponsor, the Preferred Trustee,
the Delaware Trustee or the Company Trustees accountable by reason of the
disclosure of its name and address, regardless of the source from which such
information was derived.

                .8 Maintenance of Office or Agency.

                The Company Trustees shall maintain an office or offices or
agency or agencies where Preferred Securities Certificates may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Trustees in respect of the Trust Securities Certificates may be served.
The Company Trustees initially designate State Street Bank and Trust Company,
225 Asylum Street, Hartford, Connecticut 06103, Attn: Corporate Trust
Administrations, as its principal corporate trust office for such purposes;
State Street Bank and Trust Company will use the services of Banque Generale du
Luxembourg, 50 Avenue J.F. Kennedy, L-2951 Luxembourg to perform its functions
under this Section 5.8. The Company Trustees shall give prompt written notice to
the Sponsor and to the Securityholders of any change in the location of the
Securities Register or any such office or agency.

                .9 Appointment of Paying Agent.

                (A) The Paying Agent shall make Distributions to Securityholders
from the Payment Account and shall report the amounts of such Distributions to
the Preferred Trustee (if the Preferred Trustee is not then serving as the
Paying Agent) and the Company Trustees. Any Paying Agent shall have the
revocable power to withdraw funds from the Payment Account for the purpose of
making Distributions. The Company Trustees may revoke such power and remove the
Paying Agent if such Trustees determine in their sole discretion that the Paying
Agent shall have failed to perform its obligations under this Declaration in any
material respect. The Paying Agent shall initially be the Bank, and any
co-paying agent chosen by the Bank, and acceptable to the Company Trustees and
the Sponsor. Any Person acting as Paying Agent shall be permitted to resign as
Paying Agent upon 30 days' written notice to the Company Trustees and the
Preferred Trustee (if the Preferred Trustee is not then serving as the Paying
Agent). In the event that the Bank shall no longer be the Paying Agent or a
successor Paying Agent shall resign or its authority to act be revoked, the
Company Trustees shall appoint a successor that is acceptable to the Preferred
Trustee and the Sponsor to act as Paying Agent (which shall be a bank or trust
company). The Company Trustees shall cause such successor Paying Agent or any
additional Paying Agent appointed by the Company Trustees to execute and deliver
to the Trustees an instrument in which such successor Paying Agent or additional
Paying Agent shall agree with the Trustees that as Paying Agent, such successor
Paying Agent or additional Paying Agent will hold all sums, if any, held by it
for payment to the Securityholders in trust for the benefit of the
Securityholders entitled thereto


                                       28
<PAGE>   35

until such sums shall be paid to such Securityholders. The Paying Agent shall
return all unclaimed funds to the Preferred Trustee and upon removal of a Paying
Agent such Paying Agent shall also return all funds in its possession to the
Preferred Trustee. The provisions of Sections 8.1, 8.3 and 8.6 herein shall
apply to the Bank also in its role as Paying Agent, for so long as the Bank
shall act as Paying Agent and, to the extent applicable, to any other paying
agent appointed hereunder. Any reference in this Declaration to the Paying Agent
shall include any co-paying agent unless the context requires otherwise. If the
Paying Agent shall be retained as paying agent for the payment of Liquidated
Damages by the Sponsor or its Affiliates, funds received by the Paying Agent for
the purpose of paying any such Liquidated Damages shall not constitute Trust
Property and shall not be commingled with funds or other assets of the Trust.

                (B)     If any European Union Directive on the taxation of
savings implementing the conclusions of the ECOFIN Council meeting of
26-27 November 2000 or any law implementing or complying with, or introduced in
order to conform to, such Directive is introduced, the Company Trustees shall
ensure that the Trust maintains a Paying Agent in a member state of the European
Union that will not be obliged to withhold or deduct for or on account of tax
pursuant to any such Directive or law.

                .10 Ownership of Common Securities by Sponsor.

                On the Closing Date, the Sponsor shall acquire and retain
beneficial and record ownership of the Common Securities. To the fullest extent
permitted by law, other than a transfer in connection with a consolidation or
merger of the Sponsor into another corporation, or any conveyance, transfer or
lease by the Sponsor of its properties and assets substantially as an entirety
to any Person, pursuant to Article VIII of the Indenture, any attempted transfer
of the Common Securities shall be void. The Company Trustees shall cause each
Common Securities Certificate issued to the Sponsor to contain a legend stating
"THIS CERTIFICATE IS NOT TRANSFERABLE EXCEPT AS PROVIDED IN SECTION 5.10 OF THE
DECLARATION".

                .11 Book-Entry Preferred Securities Certificates; Common
Securities Certificate.

                (A) Upon their original issuance, Preferred Securities
Certificates shall be issued in the form of one or more Book-Entry Preferred

its nominee and deposited with DTC or the Securities Registrar as custodian for
DTC for credit by DTC to the respective accounts of the Owners thereof (or such
other accounts as they may direct) in accordance with DTC's applicable rules and
procedures.

                (B) Initial Preferred Securities offered and sold to QIBs shall
be issued in the form of one or more permanent global Preferred Securities
Certificates, in substantially the form appearing in Exhibit E-1 (a "Restricted
Book-Entry Preferred Securities Certificate"). Initial Preferred Securities
offered and sold in reliance on Regulation S shall be issued in the form of one
or more global Preferred Securities Certificates in temporary form
(collectively, a "Temporary Regulation S Book-Entry Preferred Securities
Certificate"), which shall be exchangeable in whole or in part for one or more
Preferred Securities Certificates in permanent form (a "Permanent Regulation S
Book-Entry Preferred Securities Certificate"


                                       29

Certificate for which it is exchangeable, the "Regulation S Book-Entry Preferred
Securities Certificates" and together with the Restricted Book-Entry Preferred
Securities Certificate, the "Book-Entry Preferred Securities Certificates"), in
accordance with Section 5.4(D) and 5.4(G). The number of Preferred Securities
Certificates represented by the Book-Entry Preferred Securities Certificates may
from time to time be increased or decreased by adjustments made on the records
of the Securities Registrar and the Clearing Agency or their nominees as herein
provided.

                (C) Each Book-Entry Preferred Securities Certificate shall
constitute a single Preferred Securities Certificate for all purposes of this
Declaration. No Owner will receive a Definitive Preferred Securities Certificate
representing such Owner's interest in such Preferred Securities, except as
provided in Section 5.13. unless and until Definitive Preferred Securities
Certificates have been issued to Owners pursuant to Section 5.13:

                        (ii) the provisions of this Section 5.11(C) shall be in
        full force and effect;

                        (iii) the Securities Registrar and the Trustees shall be
        entitled to deal with the Clearing Agency for all purposes of this
        Declaration relating to the Book-Entry Preferred Securities Certificates
        (including the giving of instructions or directions to Owners of
        Book-Entry Preferred Securities Certificates but excluding the payment
        of the Liquidation Amount of and Distributions on the Book-Entry
        Preferred Securities Certificates) as the sole Holder of Book-Entry
        Preferred Securities Certificates and shall have no obligations to the
        Owners thereof;

                        (iv) to the extent that the provisions of this Section
        5.11 conflict with any other provisions of this Declaration, the
        provisions of this Section 5.11 shall control; and

                        (v) the rights of the Owners of the Book-Entry Preferred
        Securities Certificates shall be exercised only through the Clearing
        Agency and shall be limited to those established by law and agreements
        between such Owners and the Clearing Agency and/or the Clearing Agency
        Participants. Pursuant to the Certificate Depository Agreement, unless
        and until Definitive Preferred Securities Certificates are issued
        pursuant to Section 5.13, the initial Clearing Agency will make
        book-entry transfers among the Clearing Agency Participants.

                (D)     Preferred Securities Certificates in respect of Initial
Preferred Securities and the Preferred Trustee's certificate of authentication
shall be in substantially in the form of Exhibit E-1 hereto, which is hereby
incorporated in and expressly made a part of this Declaration. Any Preferred
Securities Certificates in respect of Exchange Preferred Securities and the
Preferred Trustee's certificate of authentication shall be substantially in the
form of Exhibit E-2 hereto, which is incorporated in and expressly made a part
of this Declaration. The Preferred Securities Certificates may have notations,
legends or endorsements required by law, stock exchange rule, agreements to
which the Trust is subject, if any, or usage. Each Preferred Security
Certificate shall be dated the date of its authentication.

                (E)     A single Common Securities Certificate representing the
Common Securities shall be issued to the Sponsor in the form of a definitive
Common Securities Certificate.

                .12 Notices to Clearing Agency.

                To the extent that a notice or other communication to the Owners
is required under this Declaration, unless and until Definitive Preferred
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Preferred Trustee and the Company Trustees shall give all such notices
and communications specified herein to be given to Owners to the Clearing Agency
and the Paying Agent (if other than the Preferred Trustee), and shall have no
obligations to the Owners.

                .13 Definitive Preferred Securities Certificates.

                Notwithstanding any other provision in this Declaration, no
Book-Entry Preferred Securities Certificate may be exchanged in whole or in part
for Preferred Securities Certificates registered, and no transfer of a
Book-Entry Preferred Securities Certificate in whole or in part may be
registered, in the name of any Person other than the Clearing Agency for such
Book-Entry Preferred Securities Certificates or a nominee thereof unless (a) the
Clearing Agency advises the Trust in writing that the Clearing Agency is no
longer willing or able to properly discharge its responsibilities with respect
to the Book-Entry Preferred Securities Certificates or the Clearing Agency
ceases to be a clearing agency registered under the Exchange Act at a time when
it is required to be so registered to act as such clearing agent, and a
qualified successor shall not have been appointed by the Trust within 90 days,
(b) the Sponsor at its option advises the Trustees in writing that it elects to
terminate the book-entry system through the Clearing Agency or (c) after the
occurrence of a Declaration Event of Default, Owners of Book-Entry Preferred
Securities Certificates representing beneficial interests aggregating at least a
majority of the Liquidation Amount advise the Company Trustees in writing that
the continuation of a book-entry system through the Clearing Agency is no longer
in the best interest of the Owners of Book-Entry Preferred Securities
Certificates, then the Company Trustees shall notify the Clearing Agency and the
Clearing Agency shall notify all Owners of Book-Entry Preferred Securities
Certificates and the other Trustees of the occurrence of any such event and of
the availability of the Definitive Preferred Securities Certificates to Owners
of such class or classes, as applicable, requesting the same by delivery of a
certificate in substantially the form of Exhibit G-1 (in the case of Initial
Preferred Securities) or Exhibit G-2 (in the case of Exchange Preferred
Securities). Upon surrender to the Company Trustees of the typewritten Preferred
Securities Certificate or Certificates representing the Book-Entry Preferred
Securities Certificates by the Clearing Agency, accompanied by registration
instructions, the Company Trustees, or any one of them, shall execute the
Definitive Preferred Securities Certificates in accordance with the instructions
of the Clearing Agency. Neither the Securities Registrar nor the Trustees shall
be liable for any delay in delivery of such instructions, and each may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Preferred Securities Certificates, the Trustees
shall recognize the Holders of the Definitive Preferred Securities Certificates
as Securityholders. The Definitive Preferred Securities Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably


                                       31

acceptable to the Company Trustees, as evidenced by the execution thereof by the
Company Trustees or any one of them.

                .14 Rights of Securityholders; Waivers of Past Defaults.

                (A) The legal title to the Trust Property is vested exclusively
in the Preferred Trustee (in its capacity as such) in accordance with Section
2.9, and the Securityholders shall not have any right or title therein other
than the undivided beneficial interest in the assets of the Trust conferred by
their Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein, in this Declaration and in the Delaware Business
Trust Act. The Trust Securities shall have no preemptive or similar rights and
when issued and delivered to Securityholders against payment of the purchase
price therefor will be fully paid and nonassessable by the Trust. The Holders of
the Trust Securities, in their capacities as such, shall be entitled to the same
limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware without giving effect to principles of conflict of laws.

                (B) For so long as any Preferred Securities remain Outstanding,
if, upon a Declaration Event of Default, the Indenture Trustee fails or the
holders of not less than 25% in principal amount of the outstanding Notes fail
to declare the principal of all of the Notes to be immediately due and payable,
the Preferred Trustee may exercise such right, subject to the provisions below,
by a notice in writing to the Issuer, the Sponsor and the Indenture Trustee; and
upon any such declaration such principal amount of and the accrued interest on
all of the Notes shall become immediately due and payable, provided, that the
payment of principal and interest on such Notes shall remain subordinated to the
extent provided in the Indenture.

                At any time after such a declaration of acceleration with
respect to the Notes has been made and before a judgment or decree for payment
of the money due has been obtained by the Indenture Trustee as in the Indenture
provided, the Holders of a majority in Liquidation Amount of the Preferred
Securities, by written notice to the Preferred Trustee, the Issuer, the Sponsor
and the Indenture Trustee, may rescind and annul such declaration and its
consequences if:

                        (i) the Issuer has paid or deposited with the Indenture
Trustee a sum sufficient to pay:

                        (A) all overdue installments of interest (including any
        Additional Sums) on all of the Notes;

                        (B) the principal of (and premium, if any, on) any Notes
        which have become due otherwise than by such declaration of acceleration
        and interest thereon at the rate borne by the Notes;

                        (C) all sums paid or advanced by the Indenture Trustee
        under the Indenture and the reasonable compensation, expenses,
        disbursements and advances of the Indenture Trustee, the Preferred
        Trustee and the Delaware Trustee, their agents and counsel; and


                                       32
<PAGE>   39

                        (ii) any Note Event of Default, other than the
non-payment of the principal of the Notes which has become due solely by such
acceleration, has been cured or waived as provided in Section 5.13 of the
Indenture.

                In the case of any Declaration Event of Default, the Holder of
Common Securities will be deemed to have waived any right to act with respect to
any such Declaration Event of Default under this Declaration until the effect of
all such Declaration Events of Default with respect to the Preferred Securities
have been cured, waived or otherwise eliminated. Until any such Declaration
Event of Default with respect to the Preferred Securities has been so cured,
waived or otherwise eliminated, the Preferred Trustee shall act solely on behalf
of the Holders of Preferred Securities and not the Holder of the Common
Securities, and only the Holders of Preferred Securities will have the right to
direct the Preferred Trustee to act on their behalf.

                The holders of a majority in aggregate Liquidation Amount of the
Preferred Securities may, on behalf of the Holders of all the Preferred
Securities, waive any past default under the Indenture, except a default in the
payment of principal or interest (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Indenture Trustee) or
a default in respect of a covenant or provision which under the Indenture cannot
be modified or amended without the consent of the holder of each outstanding
Note. No such rescission shall affect any subsequent default or impair any right
consequent thereon. The Preferred Trustee shall not, as the initial holder of
the Notes, for so long as it holds such Notes waive any Note Event of Default
without the consent of Holders of a majority in aggregate Liquidation Amount of
Preferred Securities then Outstanding.

                A waiver of a Note Event of Default will constitute a waiver of
the corresponding Declaration Event of Default.

                Upon receipt by the Preferred Trustee of written notice
declaring such rescission and annulment by Holders of Preferred Securities all
or part of which is represented by Book-Entry Preferred Securities Certificates,
a record date shall be established for determining Holders of Outstanding
Preferred Securities entitled to join in such notice, which record date shall be
at the close of business on the day the Preferred Trustee receives such notice.
The Holders on such record date, or their duly designated proxies, and only such
Persons, shall be entitled to join in such notice, whether or not such Holders
remain Holders after such record date; provided, that, unless such declaration
of rescission and annulment shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of rescission and
annulment shall automatically and without further action by any Holder be
canceled and of no further effect. Nothing in this paragraph shall prevent a
Holder, or a proxy of a Holder, from giving, after expiration of such 90-day
period, a new written notice of declaration of rescission and annulment that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

                (C) For so long as any Preferred Securities remain Outstanding,
to the fullest extent permitted by law and subject to the terms of this
Declaration and the Indenture, if a Declaration Event of Default has occurred
and is continuing and such event is attributable to


                                       33
<PAGE>   40
 the failure of the Issuer to pay interest on or principal of the Notes on the
date such interest or principal is otherwise payable (or in the case of
redemption, the redemption date), then the Holders of at least 25% in
Liquidation Amount of the Preferred Securities shall have the right to appoint a
trustee (the "Special Trustee") to act on behalf of all Holders of Preferred
Securities. The Special Trustee so appointed shall represent the Holders of all
Outstanding Preferred Securities unless Holders of at least a majority in
Liquidation Amount of the Outstanding Preferred Securities appoint an
alternative Special Trustee, in which case the Special Trustee appointed in
accordance with the preceding sentence shall resign as Special Trustee. At no
time can there be more than one Special Trustee acting on behalf of the Holders
of Preferred Securities. The Special Trustee shall have the right to directly
institute a proceeding against the Issuer or the Guarantors (a "Trustee Action")
for enforcement of payment to Holders of Preferred Securities of the principal
of or interest on the Notes having a principal amount equal to the aggregate
Liquidation Amount of the Preferred Securities of such Holders. In connection
with any such Trustee Action, the rights of the Holder of the Common Securities
will be subrogated to the rights of any Holder of Preferred Securities to the
extent of any payment made by the Issuer or the Guarantors to such Holder of
Preferred Securities as a result of such Trustee Action. Except as set forth in
Section 5.14(b) and (c), the Holders of Preferred Securities shall have no right
to exercise directly any right or remedy available to the holders of, or in
respect of, the Notes; provided, however, that if the Preferred Trustee or the
Special Trustee do not enforce such payment obligations, a Holder of Preferred
Securities will have the right, to the fullest extent permitted by law, to bring
an action on behalf of the Trust to enforce the Trust's rights under the Notes
and the Indenture.

                                   ARTICLE VI
                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING



                .1 Limitations on Voting Rights.

                (A) Except as provided in this Section, in Sections 5.14, 8.10
and 10.2 and in the Indenture and as otherwise required by law, no Holder of
Preferred Securities shall have any right to vote or in any manner otherwise
control the administration, operation and management of the Trust or the
obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of an
association.

                (B) Subject to the requirement of the Preferred Trustee
obtaining an Opinion of Counsel in certain circumstances set forth in the last
sentence of this paragraph, Holders of a majority in Liquidation Amount of all
Outstanding Preferred Securities have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Preferred
Trustee (or Special Trustee, if appointed), or direct the exercise of any trust
or power conferred upon the Preferred Trustee under the Declaration including
the right to direct the Preferred Trustee, as holder of the Notes, to (i)
exercise the remedies available under the Indenture with respect to the Notes or
the Guaranties, (ii) waive any past Event of Default that is waiveable under the
Indenture, (iii) exercise any right to rescind or annul a declaration that the
principal of all the Notes shall be due and payable or (iv) consent to any
amendment, modification, or termination of the Indenture or the Notes where such
consent shall be required; provided, however, that, where a consent or action
under the Indenture would


                                       34
<PAGE>   41

require the consent or act of the holders of more than a majority of the
aggregate principal amount of Notes affected thereby, only Holders of the
percentage of the Liquidation Amount of all Outstanding Preferred Securities
which is at least equal to the percentage required under the Indenture may
direct the Preferred Trustee to give such consent or take such action; provided,
further, that the Indenture cannot be amended in any way which would cause the
Trust to fail or cease to be classified for purposes of United States Federal
income taxation as other than a grantor trust or other entity which is not
subject to United States Federal income tax at the entity level and the assets
and income of which are treated for United States Federal income tax purposes as
held and derived directly by holders of interests in the entity. The Trustees
shall not revoke any action previously authorized or approved by a vote of the
Holders of Preferred Securities, except by a subsequent vote of the Holders of
Preferred Securities. If the Preferred Trustee or the Special Trustee fails to
enforce its rights under the Notes to receive interest or principal on the Notes
on the date such interest or principal is otherwise payable (or in the case of
redemption, the redemption date), a Holder of Preferred Securities may, to the
fullest extent permitted by law, institute a legal proceeding on behalf of the
Trust against the Issuer or the Guarantors to enforce the Trust's rights under
the Notes or the Guaranties without first instituting any legal proceeding
against the Preferred Trustee or any other person or entity. Holders of
Preferred Securities shall not be able to exercise directly any other remedies
available to the holders of the Notes unless the Preferred Trustee or the
Indenture Trustee, acting for the benefit of the Preferred Trustee, fail to do
so. In such event, Holders of at least 25% in Liquidation Amount of all
Outstanding Preferred Securities shall have a right to institute such
proceedings. The Preferred Trustee shall notify all Holders of Preferred
Securities of any notice of default received from the Indenture Trustee with
respect to the Notes. Such notice shall state that such Event of Default also
constitutes a Declaration Event of Default. Except with respect to directing the
time, method and place of conducting a proceeding for a remedy, the Preferred
Trustee shall not take any of the actions described in clause (i), (ii) or (iii)
above unless the Preferred Trustee has obtained an Opinion of Counsel rendered
by a law firm having a nationally recognized tax and securities practice to the
effect that, as a result of such action, the Trust will not fail to be
classified as a grantor trust for United States Federal income tax purposes or
another entity which is not subject to United States Federal income tax at the
entity level and the assets and income of which are treated for United States
Federal income tax purposes as held and derived directly by holders of interests
in the entity.

                (C) In the event the consent of the Preferred Trustee, as the
holder of the Notes, is required under the Indenture with respect to any
amendment, modification or termination of the Indenture, the Preferred Trustee
shall request the direction of the Holders of Preferred Securities with respect
to such amendment, modification or termination and shall vote with respect to
such amendment, modification or termination as directed by a majority in
Liquidation Amount of all Outstanding Preferred Securities; provided, however,
that, where a consent under the Indenture would require the consent of the
holders of more than a majority of the aggregate principal amount of the Notes,
the Preferred Trustee may only give such consent at the direction of the Holders
of at least the same proportion in Liquidation Amount of all Outstanding
Preferred Securities; provided, further, that the Indenture cannot be amended in
any way which would cause the Trust to fail or cease to be classified for
purposes of United States Federal income taxation as other than a grantor trust
or other entity which is not subject to United States Federal income tax at the
entity level and the assets and income of which are treated for United States
Federal income tax purposes as held and derived directly


                                       35
<PAGE>   42

by holders of interests in the entity. The Preferred Trustee shall not take any
such action in accordance with the directions of the Holders of Preferred
Securities unless the Preferred Trustee has obtained an Opinion of Counsel
rendered by a law firm having a nationally recognized tax and securities
practice to the effect that for the purposes of United States Federal income tax
the Trust will not be classified as other than a grantor trust or another entity
which is not subject to United States Federal income tax at the entity level and
the assets and income of which are treated for United States Federal income tax
purposes as held and derived directly by holders of interests in the entity.

                (D) If any proposed amendment to the Declaration pursuant to
Section 10.2 provides for, or the Trustees otherwise propose to effect, (i) any
action that would adversely affect in any material respect the powers,
preferences or special rights of the Trust Securities, whether by way of
amendment to the Declaration or otherwise, or (ii) the dissolution, winding-up
or termination of the Trust, other than pursuant to the terms of this
Declaration, then the Holders of the Trust Securities as a class will be
entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of the Holders of at least a
majority in Liquidation Amount of the Trust Securities affected thereby;
provided, that if any amendment or proposal referred to in clause (i) above
would adversely affect only the Preferred Securities or the Common Securities,
then only the affected class will be entitled to vote on such amendment or
proposal and such amendment or proposal shall not be effective except with the
approval of at least a majority in Liquidation Amount of such class of Trust
Securities.

                (E) Notwithstanding that Holders of Preferred Securities are
entitled to vote or consent under any of the circumstances described herein, any
of the Preferred Securities that are owned at such time by the Sponsor or any
entity directly or indirectly controlling or controlled by, or under direct or
indirect common control with, the Sponsor, shall not be entitled to vote or
consent and shall, for purposes of such vote or consent, be treated as if such
Preferred Securities were not Outstanding.

                (F) Holders of Preferred Securities will have no rights to
appoint or remove, or increase or decrease the number of, the Trustees, who may
be appointed, removed or replaced, increased or decreased solely by the Sponsor
as the indirect or direct Holder of all of the Common Securities. No vote or
consent of the Holders of Preferred Securities will be required for the Trust to
redeem and cancel Preferred Securities or distribute Notes in accordance with
the Declaration.

                .2 Notice of Meetings.

                Notice of all meetings at which the Preferred Securityholders
are entitled to vote shall be given by the Preferred Trustee pursuant to Section
10.9 to each Preferred Securityholder of record, at his registered address, at
least 15 days and not more than 90 days before the meeting. Notice of all
matters upon which action by written consent of the Preferred Securityholders is
to be taken shall be given by the Preferred Trustee pursuant to Section 10.9 to
each Preferred Securityholder of record, at his registered address,
contemporaneously with any request for or solicitation of such consents. Each
such notice shall include a statement setting forth the following information:
(i) the date, place and purpose of such meeting or the date by which such action
is to be taken and the purpose thereof; (ii) a description of any resolution
proposed for adoption at such meeting on which


                                       36
<PAGE>   43

such Holders are entitled to vote or of such matter upon which written consent
is sought; and (iii) instructions for the delivery of proxies or consents. At
any such meeting, any business properly before the meeting may be so considered
whether or not stated in the notice of the meeting. Any adjourned meeting may be
held as adjourned without further notice.

                .3 Meetings of Preferred Securityholders.

                Any required approval or direction of Holders of Preferred
Securities may be given at a separate meeting of Holders of Preferred Securities
convened for such purpose, at a meeting of all of the Holders of Trust
Securities or pursuant to written consent. No annual meeting of Securityholders
is required to be held. The Company Trustees, however, shall call a meeting of
Securityholders to vote on any matter upon the written request of the Preferred
Securityholders of record of 25% of the Preferred Securities (based upon their
Liquidation Amount) and the Company Trustees or the Preferred Trustee may, at
any time in their discretion, call a meeting of Preferred Securityholders to
vote on any matters as to which Preferred Securityholders are entitled to vote.

                Preferred Securityholders of record of 50% of the Outstanding
Preferred Securities (based upon their Liquidation Amount), present in person or
by proxy, shall constitute a quorum at any meeting of Securityholders.

                If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding more
than a majority of the Preferred Securities (based upon their Liquidation
Amount) held by the Preferred Securityholders of record present, either in
person or by proxy, at such meeting shall constitute the action of the
Securityholders, unless this Declaration requires a greater number of
affirmative votes.

                .4 Voting Rights.

                Securityholders shall be entitled to one vote for each $1,000 of
Liquidation Amount represented by their Trust Securities in respect of any
matter as to which such Securityholders are entitled to vote.

                .5 Proxies, etc.

                At any meeting of Securityholders, any Securityholder entitled
to vote thereat may vote by proxy, provided, that no proxy shall be voted at any
meeting unless it shall have been placed on file with the Company Trustees, or
with such other officer or agent of the Trust as the Company Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Proxies may be solicited in the name of the Preferred Trustee or one or more
officers of the Preferred Trustee. Only Securityholders of record shall be
entitled to vote. When Trust Securities are held jointly by several persons, any
one of them may vote at any meeting in person or by proxy in respect of such
Trust Securities, but if more than one of them shall be present at such meeting
in person or by proxy, and such joint owners or their proxies so present
disagree as to any vote to be cast, such vote shall not be received in respect
of such Trust Securities. A proxy purporting to be executed by or on behalf of a
Securityholder shall be deemed valid unless challenged at or prior to its
exercise, and the burden of proving


                                       37
<PAGE>   44

invalidity shall rest on the challenger. No proxy shall be valid more than three
years after its date of execution.

                .6 Securityholder Action by Written Consent.

                Any action which may be taken by Securityholders at a meeting
may be taken without a meeting if Securityholders holding more than a majority
of all Outstanding Trust Securities (based upon their Liquidation Amount)
entitled to vote in respect of such action (or such larger proportion thereof as
shall be required by any express provision of this Declaration) shall consent to
the action in writing. Any such action shall be effective at the time specified
in or determined in accordance with the notice distributed pursuant to Section
6.2 hereof.

                .7 Record Date for Voting and Other Purposes.

                For the purposes of determining the Securityholders who are
entitled to notice of and to vote at any meeting or by written consent, or to
participate in any Distribution on the Trust Securities in respect of which a
record date is not otherwise provided for in this Declaration, or for the
purpose of any other action, the Company Trustees may from time to time fix a
date, not more than 90 days prior to the date of any meeting of Securityholders
or the payment of a distribution or other action, as the case may be, as a
record date for the determination of the identity of the Securityholders of
record for such purposes.

                .8 Acts of Securityholders.

                Any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted by this Declaration to be given,
made or taken by Securityholders or Owners may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such
Securityholders or Owners in person or by an agent duly appointed in writing;
and, except as otherwise expressly provided herein, such action shall become
effective when such instrument or instruments are delivered to a Company
Trustee. Such instrument or instruments (and the action embodied therein and
evidenced thereby) are herein sometimes referred to as the "Act" of the
Securityholders or Owners signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Declaration and (subject to Section 8.1)
conclusive in favor of the Trustees, if made in the manner provided in this
Section.

                The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which any Trustee receiving the same deems sufficient.


                                       38
<PAGE>   45

                The ownership of Preferred Securities shall be proved by the
Securities Register.

                Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Securityholder of any Trust Security shall bind every
future Securityholder of the same Trust Security and the Securityholder of every
Trust Security issued upon the registration of transfer thereof or in exchange
therefor or in lieu thereof in respect of anything done, omitted or suffered to
be done by the Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

                Without limiting the foregoing, a Securityholder entitled
hereunder to take any action hereunder with regard to any particular Trust
Security may do so with regard to all or any part of the Liquidation Amount of
such Trust Security or by one or more duly appointed agents each of which may do
so pursuant to such appointment with regard to all or any part of such
liquidation amount.

                If any dispute shall arise between the Securityholders and the
Company Trustees or among such Securityholders or Trustees with respect to the
authenticity, validity or binding nature of any request, demand, authorization,
direction, consent, waiver or other Act of such Securityholder or Trustee under
this Article VI, then the determination of such matter by the Preferred Trustee
shall be conclusive with respect to such matter.

                A Securityholder may institute a legal proceeding directly
against the Sponsor under the Trust Guarantee to enforce its rights under the
Trust Guarantee without first instituting a legal proceeding against the
Guarantee Trustee (as defined in the Guarantee Agreement), the Trust or any
person or entity.

                .9 Inspection of Records.

                Upon reasonable notice to the Company Trustees and the Preferred
Trustee, the records of the Trust shall be open to inspection by Securityholders
during normal business hours for any purpose reasonably related to such
Securityholder's interest as a Securityholder.

                        (H) there are no proceedings pending or, to the best of
        each of the Preferred Trustee's and the Delaware Trustee's knowledge,
        threatened against or affecting the Preferred Trustee or the Delaware
        Trustee in any court or before any governmental authority, agency or
        arbitration board or tribunal which, individually or in the aggregate,
        would materially and adversely affect the Trust or would question the
        right, power and authority of the Preferred Trustee or the Delaware
        Trustee, as the case may be, to enter into or perform its obligations as
        one of the Trustees under this Declaration.

                .2 Representations and Warranties of Sponsor.

                The Sponsor hereby represents and warrants for the benefit of
the Securityholders that:

                        (A) the Trust Securities Certificates issued on the
        Closing Date on behalf of the Trust have been duly authorized and will
        have been duly and validly executed, issued and delivered by the
        Trustees pursuant to the terms and provisions of, and in accordance with
        the requirements of, this Declaration and the Securityholders will be,
        as of each such date, entitled to the benefits of this Declaration;

                        (B) there are no taxes, fees or other governmental
        charges payable by the Trust (or the Trustees on behalf of the Trust)
        under the laws of the State of Delaware or any political subdivision
        thereof in connection with the execution, delivery and performance by
        the Preferred Trustee or the Delaware Trustee, as the case may be, of
        this Declaration; and

                        (C) to its knowledge, since the date of the creation of
        the Trust through the date hereof, no Trust Securities have been issued
        and the Trust has not conducted any business nor incurred any
        liabilities and the Trust has not been caused to conduct any business
        nor to incur any liabilities.

                                  ARTICLE VIII
                                  THE TRUSTEES

                .1 Certain Duties and Responsibilities.

                (A) The duties and responsibilities of the Trustees shall be as
provided by this Declaration and, in the case of the Preferred Trustee, subject
to Section 10.11(a) hereof, the Trust Indenture Act. Notwithstanding the
foregoing, no provision of this Declaration shall require the Trustees to expend
or risk their own funds or otherwise incur any financial liability in the
performance of any of their duties hereunder, or in the exercise of any of their
rights or powers, if they shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it. Whether or not therein expressly so provided,
every provision of this Declaration relating to the conduct or affecting the
liability of or affording protection to the Trustees shall be subject to the
provisions of this Section 8.1. Nothing in this Declaration shall be construed
to release the Preferred Trustee from liability for its own negligent action,
its own negligent failure to act, or its own willful misconduct. The Delaware
Trustee shall have no personal liability under this Declaration except to the
Trust, the Sponsor and the Holders for its gross negligence or willful


                                       41
<PAGE>   48

misconduct. To the extent that, at law or in equity, a Company Trustee or the
Delaware Trustee has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, such Company Trustee or
the Delaware Trustee shall not be liable to the Trust or to any Securityholder
for such Trustee's good faith reliance on the provisions of this Declaration.
The provisions of this Declaration, to the extent that they restrict the duties
and liabilities of the Company Trustees and the Delaware Trustee otherwise
existing at law or in equity, are agreed by the Sponsor and the Securityholders
to replace such other duties and liabilities of the Company Trustees and the
Delaware Trustee.

                (B) All payments made by the Preferred Trustee or a Paying Agent
in respect of the Trust Securities shall be made only from the revenue and
proceeds from the Trust Property and only to the extent that there shall be
sufficient revenue or proceeds from the Trust Property to enable the Preferred
Trustee or a Paying Agent to make payments in accordance with the terms hereof.
Each Securityholder, by its acceptance of a Trust Security, agrees that it will
look solely to the revenue and proceeds from the Trust Property to the extent
legally available for distribution to it as herein provided and that the
Trustees are not personally liable to it for any amount distributable in respect
of any Trust Security or for any other liability in respect of any Trust
Security. This Section 8.1(b) does not limit the liability of the Trustees
expressly set forth elsewhere in this Declaration or, in the case of the
Preferred Trustee, in the Trust Indenture Act.

                (C) Subject to Section 5.14 hereof, if a Declaration Event of
Default has occurred and is continuing, the Preferred Trustee shall enforce this
Declaration for the benefit of the Holders. The Preferred Trustee, before the
occurrence of any Declaration Event of Default and after the curing of all
Declaration Events of Default that may have occurred, shall undertake to perform
only such duties as are specifically set forth in this Declaration (including
pursuant to Section 10.11), and no implied covenants shall be read into this
Declaration against the Preferred Trustee. If a Declaration Event of Default has
occurred (that has not been cured or waived pursuant to Section 5.14), the
Preferred Trustee shall exercise such of the rights and powers vested in it by
this Declaration, and use the same degree of care and skill in its exercise
thereof, as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs.

                (D) No provision of this Declaration shall be construed to
relieve the Preferred Trustee from liability for its own negligent action, its
own negligent failure to act, or its own willful misconduct, except that:

                        (i) the Preferred Trustee shall not be liable for any
error of judgment made in good faith by an authorized officer of the Preferred
Trustee, unless it shall be proved that the Preferred Trustee was negligent in
ascertaining the pertinent facts;

                        (ii) the Preferred Trustee shall not be liable with
respect to any action taken or omitted to be taken by it in good faith in
accordance with the direction of the Holders of not less than a majority in
Liquidation Amount of the Trust Securities relating to the time, method and
place of conducting any proceeding for any remedy available to the Preferred
Trustee, or exercising any trust or power conferred upon the Preferred Trustee
under this Declaration;


                                       42
<PAGE>   49

                        (iii) the Preferred Trustee's sole duty with respect to
the custody, safe keeping and physical preservation of the Notes and the Payment
Account shall be to deal with such Property in a similar manner as the Preferred
Trustee deals with similar property for its own account, subject to the
protections and limitations on liability afforded to the Preferred Trustee under
this Declaration and the Trust Indenture Act;

                        (iv) the Preferred Trustee shall not be liable for any
interest on any money received by it except as it may otherwise agree with the
Sponsor; and money held by the Preferred Trustee need not be segregated from
other funds held by it except in relation to the Payment Account maintained by
the Preferred Trustee pursuant to Section 3.1 and except to the extent otherwise
required by law; and

                        (v) the Preferred Trustee shall not be responsible for
monitoring the compliance by the Company Trustees or the Sponsor with their
respective duties under this Declaration, nor shall the Preferred Trustee be
liable for the default or misconduct of the Company Trustees or the Sponsor.

                .2 Certain Notices.

                Within five Business Days after the occurrence of any
Declaration Event of Default actually known to an officer in the Corporate Trust
Administration office of the Preferred Trustee, the Preferred Trustee shall
transmit, in the manner and to the extent provided in Section 10.9, notice of
such Declaration Event of Default to the Securityholders, the Company Trustees,
the Delaware Trustee and the Sponsor, unless such Declaration Event of Default
shall have been cured or waived.

                .3 Certain Rights of Preferred Trustee.

                Subject to the provisions of Section 8.1:

                        (A) the Preferred Trustee may rely and shall be
        protected in acting or refraining from acting in good faith upon any
        resolution, Opinion of Counsel, certificate, written representation of a
        Holder or transferee, certificate of auditors or any other certificate,
        statement, instrument, opinion, report, notice, request, consent, order,
        appraisal, bond, debenture, note, other evidence of indebtedness or
        other paper or document believed by it to be genuine and to have been
        signed or presented by the proper party or parties;

                        (B) if (i) in performing its duties under this
        Declaration the Preferred Trustee is required to decide between
        alternative courses of action or (ii) in construing any of the
        provisions of this Declaration the Preferred Trustee finds the same
        ambiguous or inconsistent with any other provisions contained herein or
        (iii) the Preferred Trustee is unsure of the application of any
        provision of this Declaration, then, except as to any matter as to which
        the Preferred Securityholders are entitled to vote under the terms of
        this Declaration, the Preferred Trustee shall deliver a notice to the
        Sponsor requesting written instructions of the Sponsor as to the course
        of action to be taken and the Preferred Trustee shall take such action,
        or refrain from taking such action, as the Preferred Trustee shall be
        instructed in writing to take, or to refrain from taking, by the
        Sponsor; provided, however, that if the Preferred Trustee does not


                                       43
<PAGE>   50

        receive such instructions of the Sponsor within ten Business Days after
        it has delivered such notice, or such reasonably shorter period of time
        set forth in such notice (which to the extent practicable shall not be
        less than five Business Days), it may, but shall be under no duty to,
        take or refrain from taking such action not inconsistent with this
        Declaration as it shall deem advisable and in the best interests of the
        Securityholders, in which event the Preferred Trustee shall have no
        liability except for its own bad faith, negligence or willful
        misconduct;

                        (C) any direction or act of the Sponsor or the Company
        Trustees contemplated by this Declaration shall be sufficiently
        evidenced by an Officers' Certificate with respect to the Sponsor and a
        certificate of any one of the Company Trustees with respect to the
        Company Trustees;

                        (D) whenever in the administration of this Declaration,
        the Preferred Trustee shall deem it desirable that a matter be
        established before undertaking, suffering or omitting any action
        hereunder, the Preferred Trustee (unless other evidence is herein
        specifically prescribed) may, in the absence of bad faith on its part,
        request and rely upon an Officers' Certificate or certificate from any
        one of the Company Trustees which, upon receipt of such request, shall
        be promptly delivered by the Sponsor or the Company Trustees;

                        (E) the Preferred Trustee shall have no duty to see to
        any recording, filing or registration of any instrument (including any
        financing or continuation statement or any filing under tax or
        securities laws) or any rerecording, refiling or re-registration
        thereof;

                        (F) the Preferred Trustee may consult with counsel
        (which counsel may be counsel to the Sponsor or any of its Affiliates,
        and may include any of its employees) and the written advice of such
        counsel shall be full and complete authorization and protection in
        respect of any action taken, suffered or omitted by it hereunder in good
        faith and in reliance thereon and in accordance with such advice, such
        counsel may be counsel to the Sponsor or any of its Affiliates, and may
        include any of its employees; the Preferred Trustee shall have the right
        at any time to seek instructions concerning the administration of this
        Declaration from any court of competent jurisdiction;

                        (G) the Preferred Trustee shall be under no obligation
        to exercise any of the rights or powers vested in it by this Declaration
        at the request or direction of any of the Securityholders pursuant to
        this Declaration, unless such Securityholders shall have offered to the
        Preferred Trustee reasonable security or indemnity against the costs,
        expenses and liabilities which might be incurred by it in compliance
        with such request or direction;

                        (H) the Preferred Trustee shall not be bound to make any
        investigation into the facts or matters stated in any resolution,
        certificate, statement, instrument, opinion, report, notice, request,
        consent, order, approval, bond, debenture, note or other evidence of
        indebtedness or other paper or document, unless requested in writing to
        do so by one or more Securityholders;


                                       44
<PAGE>   51

                        (I) the Preferred Trustee may execute any of the trusts
        or powers hereunder or perform any duties hereunder either directly or
        by or through its agents or attorneys, provided, that the Preferred
        Trustee shall be responsible for its own negligence or recklessness with
        respect to selection of any agent or attorney appointed by it hereunder;

                        (J) whenever in the administration of this Declaration
        the Preferred Trustee shall deem it desirable to receive instructions
        with respect to enforcing any remedy or right or taking any other action
        hereunder the Preferred Trustee (i) may request instructions from the
        Holders of the Trust Securities which instructions may only be given by
        the Holders of the same proportion in Liquidation Amount of the Trust
        Securities as would be entitled to direct the Preferred Trustee under
        the terms of the Trust Securities in respect of such remedy, right or
        action, (ii) may refrain from enforcing such remedy or right or taking
        such other action until such instructions are received, and (iii) shall
        be protected in acting in accordance with such instructions;

                        (K) except as otherwise expressly provided by this
        Declaration, the Preferred Trustee shall not be under any obligation to
        take any action that is discretionary under the provisions of this
        Declaration; and

                        (l) if the Initial Purchasers named in the Purchase
        Agreement request or if the Clearing Agency requires that the Preferred
        Securities be identified on the Clearing Agency records by reference to
        the liquidation amount or in increments of the liquidation value of the
        Preferred Securities, the Preferred Trustee is authorized to take any
        actions necessary to comply with such request or requirement.

                No provision of this Declaration shall be deemed to impose any
duty or obligation on the Preferred Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it, in any
jurisdiction in which it shall be illegal, or in which the Preferred Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts, or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Preferred Trustee
shall be construed to be a duty.

                .4 Not Responsible for Recitals or Issuance of Securities.

                The recitals contained herein and in the Trust Securities
Certificates shall be taken as the statements of the Trust, and the Trustees
(other than the Company Trustees) do not assume any responsibility for their
correctness. The Trustees (other than the Company Trustees) shall not be
accountable for the use or application by the Sponsor or the Issuer of the
proceeds of the Notes.

                .5 May Hold Securities.

                Except as provided in the definition of the term "Outstanding"
in Article I, any Trustee or any other agent of any Trustee or the Trust, in its
individual or any other capacity, may become the owner or pledgee of Trust
Securities and, subject to Sections 8.8 and 8.13, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

                .6 Compensation; Indemnity; Fees.

                The Sponsor agrees:

                        (A) to pay to the Trustees and to any Paying Agent
        appointed by the Sponsor from time to time reasonable compensation for
        all services rendered by them hereunder (which compensation shall not be
        limited by any provision of law in regard to the compensation of a
        trustee of an express trust);

                        (B) except as otherwise expressly provided herein, to
        reimburse the Trustees and Paying Agent upon request for all reasonable
        expenses, disbursements and advances incurred or made by the Trustees
        and Paying Agent in accordance with any provision of this Declaration
        (including the reasonable compensation and the expenses and
        disbursements of its agents and counsel), except any such expense,
        disbursement or advance as may be attributable to its negligence (or, in
        the case of the Delaware Trustee, gross negligence) or bad faith;

                        (C) to the fullest extent permitted by applicable law,
        to indemnify and hold harmless (i) each Trustee, (ii) each Paying Agent,
        (iii) any Affiliate of any Trustee (other than the Sponsor), (iv) any
        officer, director, shareholder, employee, representative or agent of any
        Trustee, and (v) any employee or agent of the Trust or its Affiliates
        (other than the Sponsor) (referred to herein as an "Indemnified
        Person"), from and against any loss, damage, liability, tax, penalty,
        expense or claim of any kind or nature whatsoever incurred by such
        Indemnified Person by reason of the creation, operation or termination
        of the Trust or any act or omission performed or omitted by such
        Indemnified Person in good faith on behalf of the Trust and in a manner
        such Indemnified Person reasonably believed to be within the scope of
        authority conferred on such Indemnified Person by this Declaration,
        except that no Indemnified Person shall be entitled to be indemnified in
        respect of any loss, damage or claim incurred by such Indemnified Person
        by reason of its negligence (or, in the case of the Delaware Trustee and
        its related Indemnified Persons, gross negligence) or willful misconduct
        with respect to such acts or omissions; and

                        (D) to the fullest extent permitted by applicable law,
        to advance expenses (including legal fees) incurred by an Indemnified
        Person in defending any claim, demand, action, suit or proceeding, from
        time to time, prior to the final disposition of such claim, demand,
        action, suit or proceeding upon receipt by the Sponsor of (i) a written
        affirmation by or on behalf of the Indemnified Person of its or his good
        faith belief that it or he has met the standard of conduct set forth in
        this Section 8.6 and (ii) an undertaking by or on behalf of the
        Indemnified Person to repay such amount if it shall be determined that
        the Indemnified Person is not entitled to be indemnified as authorized
        in the preceding subsection.

                The provisions of this Section 8.6 shall survive the termination
of this Declaration and the removal or resignation of any Trustee or Paying
Agent.

                No Trustee may claim any lien or charge on any Trust Property as
a result of any amount due pursuant to this Section 8.6.

                The Sponsor, the Issuer (subject to the Indenture) and any
Trustee may engage in or possess an interest in other business ventures of any
nature or description, independently or with others, similar or dissimilar to
the business of the Trust, and the Trust and the Holders of Trust Securities
shall have no rights by virtue of this Declaration in and to such independent
ventures or the income or profits derived therefrom, and the pursuit of any such
venture, even if competitive with the business of the Trust, shall not be deemed
wrongful or improper. Neither the Sponsor, nor any Trustee, shall be obligated
to present any particular investment or other opportunity to the Trust even if
such opportunity is of a character that, if presented to the Trust, could be
taken by the Trust, and the Sponsor or any Trustee shall have the right to take
for its own account (individually or as a partner or fiduciary) or to recommend
to others any such particular investment or other opportunity. Any Trustee may
engage or be interested in any financial or other transaction with the Sponsor
or any Affiliate of the Sponsor, or may act as depository for, trustee or agent
for, or act on any committee or body of holders of, securities or other
obligations of the Sponsor or its Affiliates.

                .7 Corporate Preferred Trustee Required; Eligibility of

                (A) There shall at all times be a Preferred Trustee hereunder
with respect to the Trust Securities. The Preferred Trustee shall be a Person
that is eligible pursuant to the Trust Indenture Act to act as such and has a
combined capital and surplus of at least $50,000,000. If any such Person
publishes reports of condition at least annually, pursuant to law or to the
requirements of its supervising or examining authority, then for the purposes of
this Section, the combined capital and surplus of such Person shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. If at any time the Preferred Trustee with respect to the
Trust Securities shall cease to be eligible in accordance with the provisions of
this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

                (B) There shall at all times be one or more Company Trustees
hereunder with respect to the Trust Securities. Each Company Trustee shall be
either a natural person who is at least 21 years of age or a legal entity that
shall act through one or more persons authorized to bind that entity.

                (C) There shall at all times be a Delaware Trustee with respect
to the Trust Securities. The Delaware Trustee shall either be (i) a natural
person who is at least 21 years of age and a resident of the State of Delaware
or (ii) a legal entity with its principal place of business in the State of
Delaware and that otherwise meets the requirements of applicable Delaware law
that shall act through one or more persons authorized to bind such entity.

                .8 Conflicting Interests.

                (A) If the Preferred Trustee has or shall acquire a conflicting
interest within the meaning of the Trust Indenture Act, the Preferred Trustee
shall either eliminate such interest or resign, to the extent and in the manner
provided by, and subject to the provisions of, the Trust Indenture Act and this
Declaration.

                (B) The Guarantee Agreement and the Indenture as well as the
Guarantee Agreements, Declarations and Indentures relating to the 9% Trust

                                       47
<PAGE>   54

Medical Care Capital Trust II and the 7 3/8% DM Trust Preferred Securities of
Fresenius Medical Care Capital Trust III shall be deemed to be specifically
described in this Declaration for the purposes of clause (i) of the first
proviso contained in Section 310(b) of the Trust Indenture Act.

                .9 Co-Trustees and Separate Trustee.

                Unless a Declaration Event of Default shall have occurred and be
continuing, at any time or times, for the purpose of meeting the legal
requirements of the Trust Indenture Act or of any jurisdiction in which any part
of the Trust Property may at the time be located, the Sponsor and the Company
Trustees, by agreed action of the majority of such Trustees, shall have power to
appoint, and upon the written request of the Company Trustees, the Sponsor shall
for such purpose join with the Company Trustees in the execution, delivery, and
performance of all instruments and agreements necessary or proper to appoint,
one or more Persons approved by the Preferred Trustee either to act as
co-trustee, jointly with the Preferred Trustee, of all or any part of such Trust
Property, or to the extent required by law to act as separate trustee of any
such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such Person or Persons in the capacity
aforesaid, any property, title, right or power deemed necessary or desirable,
subject to the other provisions of this Section. If the Sponsor does not join in
such appointment within 15 days after the receipt by it of a request so to do,
or in case a Declaration Event of Default has occurred and is continuing, the
Preferred Trustee alone shall have power to make such appointment. Any co-
trustee or separate trustee appointed pursuant to this Section shall either be
(i) a natural person who is at least 21 years of age and a resident of the
United States or (ii) a legal entity with its principal place of business in the
United States that shall act through one or more persons authorized to bind such
entity.

                Should any written instrument from the Sponsor be required by
any co-trustee or separate trustee so appointed for more fully confirming to
such co-trustee or separate trustee such property, title, right, or power, any
and all such instruments shall, on request, be executed, acknowledged and
delivered by the Sponsor.

                Every co-trustee or separate trustee shall, to the extent
permitted by law, but to such extent only, be appointed subject to the following
terms, namely:

                        (A) The Trust Securities shall be executed,
        authenticated and delivered and all rights, powers, duties, and
        obligations hereunder in respect of the custody of securities, cash and
        other personal property held by, or required to be deposited or pledged
        with, the Trustees specified hereunder, shall be exercised, solely by
        such Trustees and not by such co-trustee or separate trustee.

                        (B) The rights, powers, duties, and obligations hereby
        conferred or imposed upon the Preferred Trustee in respect of any
        property covered by such appointment shall be conferred or imposed upon
        and exercised or performed by the Preferred Trustee or by the Preferred
        Trustee and such co-trustee or separate trustee jointly, as shall be
        provided in the instrument appointing such co-trustee or separate
        trustee, except to the extent that under any law of any jurisdiction in
        which any particular act is to be performed, the Preferred Trustee shall
        be incompetent or


                                       48
<PAGE>   55

        unqualified to perform such act, in which event such rights, powers,
        duties and obligations shall be exercised and performed by such
        co-trustee or separate trustee.

                        (C) The Preferred Trustee at any time, by an instrument
        in writing executed by it, with the written concurrence of the Sponsor
        and the Issuer, may accept the resignation of or remove any co-trustee
        or separate trustee appointed under this Section, and, in case a
        Declaration Event of Default has occurred and is continuing, the
        Preferred Trustee shall have power to accept the resignation of, or
        remove, any such co-trustee or separate trustee without the concurrence
        of the Sponsor. Upon the written request of the Preferred Trustee, the
        Sponsor and the Issuer shall join with the Preferred Trustee in the
        execution, delivery and performance of all instruments and agreements
        necessary or proper to effectuate such resignation or removal. A
        successor to any co-trustee or separate trustee so resigned or removed
        may be appointed in the manner provided in this Section.

                        (D) No co-trustee or separate trustee hereunder shall be
        personally liable by reason of any act or omission of the Preferred
        Trustee or any other trustee hereunder.

                        (E) The Preferred Trustee shall not be liable by reason
        of any act or omission of a co-trustee or separate trustee.

                        (F) Any Act of Holders delivered to the Preferred
        Trustee shall be deemed to have been delivered to each such co-trustee
        and separate trustee.

                .10 Resignation and Removal; Appointment of Successor.

                No resignation or removal of any Trustee (the "Relevant
Trustee") and no appointment of a successor Trustee pursuant to this Article
shall become effective until the acceptance of appointment by the successor
Trustee in accordance with the applicable requirements of Section 8.11.

                Subject to the immediately preceding paragraph, the Relevant
Trustee may resign at any time by giving written notice thereof to the
Securityholders, the Sponsor, the Issuer and the other Trustees. If the
instrument of acceptance by the successor Trustee required by Section 8.11 shall
not have been delivered to the Relevant Trustee within 30 days after the giving
of such notice of resignation, the Relevant Trustee may petition, at the expense
of the Trust, any court of competent jurisdiction for the appointment of a
successor Relevant Trustee.

                Unless a Declaration Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder(s). If a Declaration Event of Default shall have occurred and be
continuing, the Preferred Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). A Company Trustee may be
removed by the Common Securityholder(s) at any time.


                                       49
<PAGE>   56

                If any Trustee shall resign, be removed or become incapable of
acting as Trustee, or if a vacancy shall occur in the office of any Trustee for
any cause, at a time when no Declaration Event of Default shall have occurred
and be continuing, the Common Securityholder(s), by Act of the Common
Securityholder(s) delivered to the retiring Trustee, shall promptly appoint a
successor Trustee or Trustees, and the retiring Trustee shall comply with the
applicable requirements of Section 8.11. If the Preferred Trustee or the
Delaware Trustee shall resign, be removed or become incapable of continuing to
act as the Preferred Trustee or the Delaware Trustee, as the case may be, at a
time when a Declaration Event of Default shall have occurred and be continuing,
the Preferred Securityholders, by Act of the Securityholders of a majority in
Liquidation Amount of the Preferred Securities then Outstanding delivered to the
retiring Relevant Trustee, shall promptly appoint a successor Relevant Trustee
or Trustees, and such successor Trustee shall comply with the applicable
requirements of Section 8.11. If a Company Trustee shall resign, be removed or
become incapable of acting as Company Trustee, at a time when a Declaration
Event of Default shall have occurred and be continuing, the Common
Securityholder(s) by Act of the Common Securityholder(s) delivered to the
Company Trustee shall promptly appoint a successor Company Trustee or Company
Trustees and such successor Company Trustee or Trustees shall comply with the
applicable requirements of Section 8.11. If no successor Relevant Trustee shall
have been so appointed by the Common Securityholder(s) or the Preferred
Securityholders and accepted appointment in the manner required by Section 8.11,
any Trustee may or any Securityholder who has been a Securityholder of Trust
Securities for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

                The Preferred Trustee shall give notice of each resignation and
each removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.9 and shall give notice to
the Sponsor. Each notice shall include the name of the successor Relevant
Trustee and the address of its Corporate Trust Office if it is the Preferred
Trustee.

                Notwithstanding the foregoing or any other provision of this
Declaration, in the event any Company Trustee or a Delaware Trustee who is a
natural person dies or becomes, in the opinion of the Sponsor, incompetent or
incapacitated, the vacancy created by such death, incompetence or incapacity may
be filled by (a) the unanimous act of remaining Company Trustees if there are at
least two of them or (b) otherwise by the Sponsor (with the successor in each
case being a Person who satisfies the eligibility requirement for Company
Trustees or Delaware Trustee, as the case may be, set forth in Section 8.7).

                .11 Acceptance of Appointment by Successor.

                In case of the appointment hereunder of a successor Trustee such
successor Trustee so appointed shall execute, acknowledge and deliver to the
Trust and to the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Sponsor or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and if the


                                       50
<PAGE>   57

Preferred Trustee is the resigning Trustee shall duly assign, transfer and
deliver to the successor Trustee all property and money held by such retiring
Preferred Trustee hereunder.

                In case of the appointment hereunder of a successor Relevant
Trustee, the retiring Relevant Trustee and each successor Relevant Trustee with
respect to the Trust Securities shall execute and deliver an amendment hereto
wherein each successor Relevant Trustee shall accept such appointment and which
(a) shall contain such provisions as shall be necessary or desirable to transfer
and confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee with respect to the
Trust Securities and the Trust and (b) shall add to or change any of the
provisions of this Declaration as shall be necessary to provide for or
facilitate the administration of the Trust by more than one Relevant Trustee, it
being understood that nothing herein or in such amendment shall constitute such
Relevant Trustees co-trustees and upon the execution and delivery of such
amendment the resignation or removal of the retiring Relevant Trustee shall
become effective to the extent provided therein and each such successor Relevant
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties of the retiring Relevant Trustee; but,
on request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant Trustee hereunder with respect to the Trust Securities and the Trust.

                Upon request of any such successor Relevant Trustee, the Trust
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Relevant Trustee all such rights, powers and
trusts referred to in the first or second preceding paragraph, as the case may
be.

                No successor Relevant Trustee shall accept its appointment
unless at the time of such acceptance such successor Relevant Trustee shall be
qualified and eligible under this Article.

                .12 Merger, Conversion, Consolidation or Succession to Business.

                Any corporation, association or other entity into which the
Preferred Trustee or the Delaware Trustee may be merged or converted or with
which it may be consolidated, or any corporation, association or other entity
resulting from any merger, conversion or consolidation to which such Relevant
Trustee shall be a party, or any corporation, association or other entity
succeeding to all or substantially all the corporate trust business of such
Relevant Trustee, shall be the successor of such Relevant Trustee hereunder,
provided such corporation, association or other entity shall be otherwise
qualified and eligible under this Article, without the execution or filing of
any paper or any further act on the part of any of the parties hereto.

                .13 Preferential Collection of Claims Against Sponsor or Trust.

                If and when the Preferred Trustee shall be or become a creditor
of the Sponsor, any other Guarantor, the Issuer or the Trust (or any other
obligor upon the Preferred Securities), the Preferred Trustee shall be subject
to the provisions of the Trust Indenture Act regarding the collection of claims
against the Sponsor, any other Guarantor, the Issuer or the Trust (or any such
other obligor).

                .14 Preferred Trustee May File Proofs of Claim.

                In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other similar judicial proceeding relative to the Trust or any other obligor
upon the Trust Securities or the property of the Trust or of such other obligor
or their creditors, the Preferred Trustee (irrespective of whether any
Distributions on the Trust Securities shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the
Preferred Trustee shall have made any demand on the Trust for the payment of any
past due Distributions) shall be entitled and empowered, to the fullest extent
permitted by law, by intervention in such proceeding or otherwise:

                        (A) to file and prove a claim for the whole amount of
        any Distributions owing and unpaid in respect of the Trust Securities
        and to file such other papers or documents as may be necessary or
        advisable in order to have the claims of the Preferred Trustee
        (including any claim for the reasonable compensation, expenses,
        disbursements and advances of the Preferred Trustee, its agents and
        counsel) and of the Holders allowed in such judicial proceeding, and

                        (B) to collect and receive any moneys or other property
        payable or deliverable on any such claims and to distribute the same;


and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Preferred Trustee and, in the event the
Preferred Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Preferred Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Preferred Trustee, its
agents and counsel, and any other amounts due the Preferred Trustee.

                Nothing herein contained shall be deemed to authorize the
Preferred Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement adjustment or compensation
affecting the Trust Securities or the rights of any Holder thereof or to
authorize the Preferred Trustee to vote in respect of the claim of any Holder in
any such proceeding.

in accordance with Section 10.9, and to the Sponsor, a brief report, to the
extent required by the Trust Indenture Act, with respect to any of the following
events which may have occurred within the previous 12 months (or, in the case of
the initial report, the period since the Closing Date):

                        (i) its eligibility under Section 8.7 or, in lieu
thereof, if to the best of its knowledge it has continued to be eligible under
said Section, a written statement to such effect;


                                       52
<PAGE>   59

                        (ii) a statement that the Preferred Trustee has complied
with all of its obligations under this Declaration or, if the Preferred Trustee
has not complied in any material respect with such obligations, a description of
such noncompliance; and

                        (iii) any change in the property and funds in its
possession as Preferred Trustee since the date of its last report and any action
taken by the Preferred Trustee in the performance of its duties hereunder which
it has not previously reported and which in its opinion materially affects the
Trust Securities.

                (B) In addition, the Preferred Trustee shall transmit to
Securityholders such reports concerning the Preferred Trustee and its actions

and with the Sponsor.

                .16 Reports to the Preferred Trustee.

the form, in the manner and at the times required by Section 314 of the Trust
Indenture Act.

Trust shall provide to the Preferred Trustee such evidence of compliance with
any conditions precedent, if any, provided for in this Declaration that relate
to any of the matters set forth in Section 314 (c) of the Trust Indenture Act.

Officers' Certificate.

                .18 Number of Trustees.

                (A) The number of Trustees shall be five, provided, that the
Holder of all of the Common Securities by written instrument may increase or
decrease the number of Company Trustees. Subject to Section 8.7(c), the
Preferred Trustee and the Delaware Trustee may be the same Person, in which case
the number of Trustees may be less than five.

                (B) If a Trustee ceases to hold office for any reason and the
number of Company Trustees is not reduced pursuant to Section 8.18(a), or if the

occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10.

                (C) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul the Trust. Whenever a vacancy in the number of Company Trustees shall
occur, until such vacancy is filled by the

<PAGE>   60

appointment of an Company Trustee in accordance with Section 8.10, the Company
Trustees in office, regardless of their number (and notwithstanding any other
provision of this Agreement), shall have all the powers granted to the Company
Trustees and shall discharge all the duties imposed upon the Company Trustees by
this Declaration.

                .19 Delegation of Power.

                (A) Any Company Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his

to time to such of their number or to the Sponsor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Company Trustees or otherwise as the Company Trustees may deem expedient,
to the extent such delegation is not prohibited by applicable law or contrary to

        optional and wholly within the discretion of the Sponsor) to terminate
        the Trust and to distribute Notes to Securityholders in exchange for the
        Preferred Securities;

                        (G) the redemption of all of the Preferred Securities in
        connection with the redemption of all of the Notes;

                        (H) subject to Section 9.4(e), the occurrence of a Tax
        Event; and

                        (I) the occurrence of an Investment Company Event.

                .3 Termination.

                The respective obligations and responsibilities of the Trustees
and the Trust created and continued hereby shall terminate upon the latest to
occur of the following: (a) the distribution by the Preferred Trustee to
Securityholders upon the liquidation of the Trust pursuant to Section 9.4, or
upon the redemption or repurchase of all of the Trust Securities pursuant to
Sections 4.2, 4.8 or 4.9 of all amounts required to be distributed hereunder
upon the final payment of the Trust Securities; (b) the payment of any expenses
owed by the Trust; and (c) the discharge of all administrative duties of the
Company Trustees, including the performance of any tax reporting obligations
with respect to the Trust or the Securityholders.

                .4 Liquidation.

                (A) If an Early Termination Event specified in Section 9.2 (with
the exception of clauses (d) and (g)) occurs or upon the Expiration Date, the
Trust shall be dissolved by the Preferred Trustee and the Company Trustees as
expeditiously as such Trustees determine to be possible by distributing, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, to each Securityholder a Like Amount of Notes, subject to Section 9.4(d).
Notice of dissolution shall be given by the Preferred Trustee by first-class
mail, postage prepaid mailed not later than 30 nor more than 60 days prior to
the Liquidation Date to each Holder of Trust Securities at such Holder's address
appearing in the Securities Register. All notices of dissolution shall:

                        (i) state the Liquidation Date;

                        (ii) state that from and after the Liquidation Date, the
Trust Securities will no longer be deemed to be Outstanding and any Trust
Securities Certificates not surrendered for exchange will be deemed to represent
a Like Amount of Notes; and

                        (iii) provide such information with respect to the
mechanics by which Holders may exchange Trust Securities Certificates for Notes,
or if Section 9.4(d) applies


                                       55
<PAGE>   62

receive a Liquidation Distribution, as the Company Trustees or the Preferred
Trustee shall deem appropriate.

                (B) Except where Section 9.2(d), 9.2(g) or 9.4(d) applies, in
order to effect the dissolution of the Trust and distribution of the Notes to
Securityholders, the Preferred Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Notes in exchange for the Outstanding
Trust Securities Certificates.

                (C) Except where Section 9.2(d), 9.2(g) or 9.4(d) applies, after
the Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) certificates representing a Like Amount of Notes will be
issued to holders of Trust Securities Certificates, upon surrender of such
certificates to the Company Trustees or their agent for exchange, (iii) any
Trust Securities Certificates not so surrendered for exchange will be deemed to
represent a Like Amount of Notes, accruing interest at the rate provided for in
the Notes from the last Distribution Date on which a Distribution was made on
such Trust Securities Certificates until such certificates are so surrendered
(and until such certificates are so surrendered, no payments of interest or
principal will be made to Holders of Trust Securities Certificates with respect
to such Notes) and (iv) all rights of Securityholders holding Trust Securities
will cease, except the right of such Securityholders to receive Notes upon
surrender of Trust Securities Certificates, provided, that Termination of the
Trust shall not affect the right of the Holders of Preferred Securities to
receive Liquidated Damages under the Registration Rights Agreement as and when
provided therein.

                (D) In the event that, notwithstanding the other provisions of
this Section 9.4, whether because of an order for dissolution entered by a court
of competent jurisdiction or otherwise, distribution of the Notes in the manner
provided herein is determined by the Preferred Trustee not to be practical, the
Trust Property shall be liquidated, and the Trust shall be dissolved, wound-up
or terminated, by the Preferred Trustee in such manner as the Preferred Trustee
determines. In such event, on the date of the dissolution, winding-up or other
termination of the Trust, Securityholders will be entitled to receive out of the
assets of the Trust available for distribution to Securityholders, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, an amount equal to the Liquidation Amount per Trust Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"). If, upon any such dissolution, winding up
or termination, the Liquidation Distribution can be paid only in part because
the Trust has insufficient assets available to pay in full the aggregate
Liquidation Distribution, then, subject to the next succeeding sentence, the
amounts payable by the Trust on the Trust Securities shall be paid on a pro rata
basis (based upon Liquidation Amounts). The Holder of the Common Securities will
be entitled to receive Liquidation Distributions upon any such dissolution,
winding-up or termination pro rata (determined as aforesaid) with Holders of
Preferred Securities, except that, if a Declaration Event of Default has
occurred and is continuing, the Preferred Securities shall have a priority over
the Common Securities.

                (E) If the Early Termination Event specified in Section 9.2(h)
occurs, the Trust shall be dissolved within 90 days following the occurrence of
such Tax Event as provided in


                                       56
<PAGE>   63

this Section 9.4; provided, however, that such dissolution and distribution
shall be conditioned on (i) the Trustees' receipt of an Opinion of Counsel of a
nationally recognized independent tax counsel experienced in such matters (a "No
Recognition Opinion") which opinion may rely on published revenue rulings of the
Internal Revenue Service, to the effect that the Holders of the Preferred
Securities will not recognize any income, gain or loss for United States Federal
income tax purposes as a result of such liquidation and distribution of Notes,
and (ii) the Issuer or the Sponsor being unable to avoid such Tax Event within
such 90-day period by taking some ministerial action or pursuing some other
reasonable measure that will have no adverse effect on the Trust, the Issuer,
the Sponsor or the Holders of the Preferred Securities and will involve no
material cost. If (i) the Sponsor has received an Opinion of Counsel (a
"Redemption Tax Opinion") of a nationally recognized independent United States
or German tax counsel or advisors, or nationally recognized independent counsel
or advisors of the jurisdiction of formation of the Issuer (initially
Luxembourg), as the case may be, experienced in such matters that, as a result
of a Tax Event, there is more than an insubstantial risk that the Issuer or the
Sponsor would be precluded from deducting the interest on the Notes for United
States Federal or German income tax purposes, or for purposes of any income tax
imposed by the jurisdiction of formation of the Issuer, even after the Notes
were distributed to the Holders of the Preferred Securities upon liquidation of
the Trust as provided above, or (ii) the Trustees shall have been informed by
such tax counsel that it cannot deliver a No Recognition Opinion, the Issuer has
the right to redeem the Notes in whole, in which case all the Preferred
Securities and Common Securities will be entitled to receive the Liquidation
Distribution.

                .5 Mergers, Consolidations, Amalgamations or Replacements of the
Trust.

                The Trust may not consolidate, amalgamate, merge with or into,
or be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 9.5. At the request of the Sponsor, with the consent of the
Company Trustees and without the consent of the Holders of Preferred Securities,
the Preferred Trustee or the Delaware Trustee, the Trust may consolidate,
amalgamate, merge with or into, or be replaced by or convey, transfer or lease
its properties and assets substantially as an entirety to, a trust organized as
such under the laws of any state of the United States of America; provided, that
(i) if the Trust is not the survivor, such successor entity either (a) expressly
assumes all of the obligations of the Trust with respect to the Trust Securities
or (b) substitutes for the Trust Securities other securities having
substantially the same terms as the Trust Securities (the "Successor
Securities") so long as the Successor Securities rank the same as the Trust
Securities with respect to Distributions and payments upon liquidation,
redemption and otherwise, (ii) the Sponsor expressly appoints a trustee of such
successor entity possessing substantially the same powers and duties as the
Preferred Trustee as the holder of the Notes, (iii) the Preferred Securities or
any Successor Securities are listed or traded, or any Successor Securities will
be listed upon notification of issuance, on any national securities exchange or
other organization on which the Preferred Securities are then listed or traded,
if any, (iv) such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not cause the Preferred Securities (including any
Successor Securities) to be downgraded by any nationally recognized statistical
rating organization, (v) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Trust Securities (including any Successor
Securities) in any material respect, (vi) such successor entity has a purpose
substantially identical to that of the Trust, (vii) the Sponsor has


                                       57
<PAGE>   64

provided a guarantee to the holders of the Successor Securities with respect to
such successor entity having substantially the same terms as the Trust
Guarantee, (viii) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease the Sponsor has received an Opinion
of Counsel rendered by a law firm having a nationally recognized tax and
securities practice to the effect that (x) such successor entity will be treated
as a grantor trust for United States Federal income tax purposes or otherwise as
an entity that is not subject to United States Federal income tax at the entity
level and the assets and income of which are treated for United States Federal
income tax purposes as held and derived directly by holders of interests in the
entity, (y) following such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, neither the Sponsor nor such successor entity
will be required to register as an investment company under the 1940 Act and (z)
such merger, consolidation, amalgamation or replacement, conveyance, transfer or
lease, will not adversely affect the rights, preferences, privileges and limited
liability of the Preferred Securities in any material respect, and (ix) the
Company Trustees shall have furnished the Delaware Trustee and the Preferred
Trustee at least five Business Days' prior written notice of the consummation of
such merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease; provided, however, that the failure to provide such notice shall not
affect the validity of any such transaction. Notwithstanding the foregoing, the
Trust shall not, except with the consent of holders of 100% in Liquidation
Amount of the Trust Securities, consolidate, amalgamate, merge with or into, or
be replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, replacement, conveyance, transfer or lease
would cause the Trust or the successor entity to be classified as other than a
grantor trust for United States Federal income tax purposes or another entity
which is not subject to United States Federal income tax at the entity level and
the assets and income of which are treated for United States Federal income tax
purposes as held and derived directly by holders of interests in the entity.

                                    ARTICLE X
                            Miscellaneous Provisions

                .1 Limitation of Rights of Securityholders.

                The death or incapacity of any person having an interest,
beneficial or otherwise, in Trust Securities shall not operate to terminate this
Declaration, nor entitle the legal representatives or heirs of such person or
any Securityholder for such person, to claim an accounting, take any action or
bring any proceeding in any court for a partition or winding up of the
arrangements contemplated hereby, nor otherwise affect the rights, obligations
and liabilities of the parties hereto or any of them.

                .2 Amendment.

                (A) This Declaration may be amended from time to time by the
Trustees and the Sponsor, without the consent of any Securityholders, (i) to
cure any ambiguity, correct or supplement any provision herein which may be
inconsistent with any other provision herein, or to make any other provisions
with respect to matters or questions arising under this Declaration, which shall
not be inconsistent with the other provisions of this Declaration, or (ii) to
modify, eliminate or add to any provisions of this Declaration to such extent as
shall be


                                       58
<PAGE>   65

necessary to ensure that the Trust will be classified for United States Federal
income tax purposes as a grantor trust or other entity which is not subject to
United States Federal income tax at the entity level and the assets and income
of which are treated for United States Federal income tax purposes as held and
derived directly by holders of interests in the entity at all times that any
Trust Securities are outstanding or to ensure that the Trust will not be
required to register as an investment company under the 1940 Act, or (iii) to
reflect the establishment of procedures to affect an offer to repurchase
Preferred Securities pursuant to Sections 4.8 or 4.9; provided, however, that in
the case of clause (i) such action shall not adversely affect in any material
respect the interests of any Securityholder, and any amendments of this
Declaration shall become effective when notice thereof is given to the
Securityholders.

                (B) If any proposed amendment provides for, or the Trustees or
the Sponsor otherwise propose to effect, (i) any action that would adversely
affect the powers, preferences or special rights of the Trust Securities,
whether by way of amendment to the Declaration or otherwise or (ii) the
dissolution, winding-up or termination of the Trust other than pursuant to the
terms of the Declaration, then the Securityholders voting together as a single
class will be entitled to vote on such amendment or proposal and such amendment
or proposal shall not be effective except with the approval of at least a
majority (based upon Liquidation Amounts) of the Trust Securities affected
thereby; provided, that if any amendment or proposal referred to in clause (i)
would adversely affect only the Preferred Securities or the Common Securities,
then only the affected class will be entitled to vote on such amendment or
proposal and such amendment or proposal shall not be effective except with the
approval of at least a majority (based on Liquidation Amounts) of such class of
Trust Securities; provided, further, that no amendment or modification may be
made to the Declaration if such amendment or modification would (x) cause the
Trust to be classified for purposes of United States Federal income taxation as
other than a grantor trust or another entity which is not subject to United
States Federal income tax at the entity level and the assets and income of which
are treated for United States Federal income tax purposes as held and derived
directly by holders of interest in the entity, (y) reduce or otherwise adversely
affect the powers of the Trustees or (z) cause the Trust to be deemed an
investment company which is required to be registered under the 1940 Act.

                (C) Except as provided in Section 10.2(b) and 10.2(d) hereof,
any provision of this Declaration may be amended by the Trustees and the Sponsor
with (i) the consent of Securityholders representing not less than a majority
(based upon Liquidation Amounts) of the Trust Securities then Outstanding and
(ii) receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status for United States Federal
income tax purposes, as a grantor trust or other entity which is not subject to
United States Federal income tax at the entity level and the assets and income
of which are treated for United States Federal income tax purposes as held and
derived directly by holders of interests in the entity, or cause the Trust to be
deemed an investment company which is required to register under the 1940 Act.

                (D) In addition to and notwithstanding any other provision in
this Declaration, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
Declaration may not be amended to (i) change


                                       59
<PAGE>   66

the amount or timing of any Distribution on the Trust Securities or otherwise
adversely affect the amount of any Distribution required to be made in respect
of the Trust Securities as of a specified date or (ii) restrict the right of a
Securityholder to institute suit for the enforcement of any such payment on or
after such date; notwithstanding any other provision herein, without the
unanimous consent of the Securityholders (such consent being obtained in
accordance with Section 6.3 or 6.6 hereof), this paragraph (c) of this Section
10.2 may not be amended.

                (E) Notwithstanding any other provisions of this Declaration, no
Trustee shall enter into or consent to any amendment to this Declaration which
would cause the Trust to fail or cease to qualify for the exemption from status
of an investment company under the 1940 Act or fail or cease to be classified
for purposes of United States Federal income taxation as other than a grantor
trust or another entity which is not subject to United States Federal income tax
at the entity level and the assets and income of which are treated for United
States Federal income tax purposes as held and derived directly by holders of
interests in the entity.

                (F) Notwithstanding anything in this Declaration to the
contrary, without the consent of the Sponsor or the Issuer, this Declaration may
not be amended in a manner which imposes any additional obligation on the
Sponsor or the Issuer, as the case may be.

                (G) In the event that any amendment to this Declaration is made,
the Company Trustees shall promptly provide to the Sponsor a copy of such
amendment.

                (H) Neither the Preferred Trustee nor the Delaware Trustee shall
be required to amend this Declaration in any manner which affects its own
rights, duties or immunities under this Declaration. The Preferred Trustee and
the Delaware Trustee shall be entitled to receive an Opinion of Counsel and an
Officers' Certificate stating that any amendment to this Declaration is in
compliance with this Declaration.

                .3 Separability.

                In case any provision in this Declaration or in the Trust
Securities Certificates shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

                .4 Governing Law.

                THIS DECLARATION AND THE RIGHTS AND OBLIGATIONS OF EACH OF THE
SECURITYHOLDERS, THE TRUST AND THE TRUSTEES WITH RESPECT TO THIS DECLARATION AND
THE TRUST SECURITIES SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
LAWS OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICT OF
LAWS.

                .5 Submission to Jurisdiction.

                The Sponsor hereby appoints Fresenius Medical Care Holdings,
Inc. ("FMCH") c/o CT Corporation System through its office at 1633 Broadway, New
York, New York 10019 as its authorized agent (the "Authorized Agent") upon which
process may be


                                       60
<PAGE>   67

served in any legal action or proceeding against it with respect to its
obligations under this Declaration or the Trust Securities instituted in any
federal or state court in the Borough of Manhattan, The City of New York, by any
Trustee or the Holder of any Trust Securities and agrees that service of process
upon such authorized agent, together with written notice of said service to the
Sponsor by the person serving the same, addressed as provided in Section 10.09,
shall be deemed in every respect effective service of process upon the Sponsor
in any such legal action or proceeding, and the Sponsor hereby irrevocably
submits to the non-exclusive jurisdiction of any such court in respect of any
such legal action or proceeding. Such appointment shall be irrevocable until the
Trust has been terminated in accordance with Article IX hereof. Notwithstanding
the foregoing, the Sponsor reserves the right to appoint another Person located
or with an office in the Borough of Manhattan, The City of New York, selected in
its discretion, as a successor Authorized Agent, and upon acceptance of such
appointment by such a successor the appointment of the prior Authorized Agent
shall terminate. If for any reason FMCH or CT Corporation System ceases to be
able to act as the Authorized Agent or to have an address in the Borough of
Manhattan, The City of New York, the Sponsor will appoint a successor Authorized
Agent in accordance with the preceding sentence. The Sponsor further agrees to
take any and all action, including the filing of any and all documents and
instruments as may be necessary to continue such designation and appointment of
such agent in full force and effect until the Trust has been terminated in
accordance with Article IX hereof. Service of process upon the Authorized Agent
addressed to it at the address set forth above, as such address may be changed
within the Borough of Manhattan, The City of New York by notice given by the
Authorized Agent to the Trustees, together with written notice of such service
mailed or delivered to the Sponsor shall be deemed, in every respect, effective
service of process on the Sponsor.

                .6 Payments Due on Non-Business Day.

                If the date fixed for any payment on any Trust Security shall be
a day that is not a Business Day, then such payment need not be made on such
date but may be made on the next succeeding day that is a Business Day (except
as otherwise provided in Sections 4.1(a) and 4.2(d)), with the same force and
effect as though made on the date fixed for such payment, and no interest shall
accrue thereon for the period after such date.

                .7 Successors.

                This Declaration shall be binding upon and shall inure to the
benefit of any successor to the Sponsor, the Trust or the Relevant Trustee,
including any successor by operation of law. Except in connection with a
consolidation, merger or sale involving the Sponsor that is permitted under
Article VIII of the Indenture and pursuant to which the assignee agrees in
writing to perform the Sponsor's obligations hereunder, the Sponsor shall not
assign its obligations hereunder.

                .8 Headings.

                The Article and Section headings are for convenience only and
shall not affect the construction of this Declaration.

                .9 Reports, Notices and Demands.

provision of this Declaration is required or permitted to be given or served to
or upon any Securityholder or the Sponsor may be given or served in writing by
deposit thereof, first-class postage prepaid, in the United States mail, hand

the Issuer, to FMC Trust Finance S.a.r.l., Luxembourg-III, 7A, rue Robert
Stumper, L-2557 Luxembourg with a copy to the Sponsor. Any notice to Preferred
Securityholders shall also be given to such Owners as have, within two years
preceding the giving of such notice, filed their names and addresses with the
Preferred Trustee for that purpose. Such notice, demand or other communication
to or upon a Securityholder shall be deemed to have been sufficiently given or
made, for all purposes, upon hand delivery, mailing or transmission.

                Any notice, demand or other communication which by any provision
of this Declaration is required or permitted to be given or served to or upon
the Trust, the Preferred Trustee, the Delaware Trustee or the Company Trustees
shall be given in writing by deposit thereof, first-class postage prepaid, in
the United States mail, hand delivery or facsimile transmission, in each case,

or the Preferred Trustee.

                All notices regarding the Preferred Securities shall be
published in the Luxemburger Wort or in such other publication as required by
the rules of the Luxembourg Stock Exchange. Any notice will become effective for
all purposes on the date of its publication. There may (provided that, in the
case of Preferred Securities listed on the Luxembourg Stock Exchange, the rules
of the Luxembourg Stock Exchange so permit) be substituted for such publication
in such newspaper the delivery of the relevant notice to the applicable clearing
system for communication by it to the Securityholders. Any such notice shall be
deemed to have been given to the Securityholders on the seventh day after the
day on which the said notice was given to all applicable clearing systems. The
Company Trustees shall be responsible for compliance with this paragraph and
shall provide directions to the Preferred Trustee in connection therewith.

                .10 Agreement Not to Petition.


                                       62
<PAGE>   69

                Each of the Trustees, the Sponsor, and the Issuer agree for the
benefit of the Securityholders that, until at least one year and one day after
the Trust has been terminated in accordance with Article IX, they shall not
file, or join in the filing of, a petition against the Trust under any
bankruptcy, insolvency, reorganization or other similar law (including, without
limitation, the United States Bankruptcy Code) (collectively "Bankruptcy Laws")
or otherwise join in the commencement of any proceeding against the Trust under
any Bankruptcy Law. In the event the Sponsor takes action in violation of this
Section 10.10, the Preferred Trustee agrees, for the benefit of Securityholders,
that at the expense of the Sponsor, it shall file an answer with the bankruptcy
court or otherwise properly contest the filing of such petition by the Sponsor
against the Trust or the commencement of such action and raise the defense that
the Sponsor has agreed in writing not to take such action and should be stopped
and precluded therefrom and such other defenses, if any, as counsel for the
Trustee or the Trust may assert. The provisions of this Section 10.10 shall
survive the termination of this Declaration.

                .11 Trust Indenture Act; Conflict with Trust Indenture Act.

                (A) This Declaration shall be subject to and governed by the
Trust Indenture Act upon the consummation of the Exchange Offer pursuant to the
Registration Rights Agreement. Until such Exchange Offer, the Trust Indenture
Act shall not apply to this Declaration, except to the extent otherwise
expressly provided herein.

                (B) The Preferred Trustee shall be the only Trustee which is a
trustee for the purposes of the Trust Indenture Act.

                (C) If any provision hereof limits, qualifies or conflicts with
another provision hereof which is required to be included in this Declaration by
any of the provisions of the Trust Indenture Act, such required provision shall
control. If any provision of this Declaration modifies or excludes any provision
of the Trust Indenture Act which may be so modified or excluded, the latter
provision shall be deemed to apply to this Declaration as so modified or
excluded, as the case may be.

                (D) The application of the Trust Indenture Act to this
Declaration shall not affect the nature of the Securities as equity securities
representing undivided beneficial interests in the assets of the Trust.

                               REVERSE OF SECURITY

                Distributions payable on each Common Security will be fixed at a
rate per annum of 7 7/8% (the "Distribution Rate") of the Liquidation Amount of
$1,000 per Common Security, such rate being the rate of interest payable on the
Notes held by the Preferred Trustee. Distributions in arrears for more than one
quarter (and interest thereon) will bear interest thereon compounded quarterly
at the Distribution Rate (to the extent permitted by applicable law). The term
"Distributions," as used herein, includes such cash distribution and any such
interest payable unless otherwise stated. A Distribution is payable only to the
extent that payments are made in respect of the Notes held by the Preferred
Trustee and to the extent the Preferred Trustee has funds on hand in the Payment
Account legally available therefor.

                Distributions on the Common Securities will accumulate from the
most recent date to which Distributions have been paid or, if no Distributions
have been paid, from June 6, 2001, and will be payable quarterly in arrears on

of debt of, or other similar proceedings affecting, the Trust or any of the
assets of the Trust.

                There shall be no obligation of the Beneficiaries to give notice
to, or obtain the consent of, the Company with respect to the happening of any
of the foregoing.

                Distributions payable on each Preferred Security will be fixed
at a rate per annum of 7 7/8% (the "Distribution Rate") of the Liquidation
Amount of $1,000 per Preferred Security, such rate being the rate of interest
payable on the Notes held by the Preferred Trustee. Distributions in arrears for
more than one quarter (and interest thereon) will bear interest thereon
compounded quarterly at the Distribution Rate (to the extent permitted by
applicable law). The term "Distributions," as used herein, includes such cash
distribution and any such interest payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of

has funds on hand in the Payment Account legally available therefor.

                Distributions on the Preferred Securities will accumulate from
the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from June 6, 2001 and will be payable quarterly in
arrears on March 15, June 15, September 15 and December 15, of each year,
commencing on September 15, 2001. Distributions will be computed on the basis of

than a full calendar month, the number of days elapsed in such month. Under the
terms and conditions of, and in the circumstances set forth in, the Registration
Rights Agreement referred to in the Declaration, Liquidated Damages (as defined

satisfaction of liabilities to creditors of the Trust, cause the Notes to be
distributed by the Preferred Trustee to the holders of the Preferred Securities

                               REVERSE OF SECURITY

                Distributions payable on each Preferred Security will be fixed
at a rate per annum of 7 7/8% (the "Distribution Rate") of the Liquidation
Amount of $1,000 per Preferred Security, such rate being the rate of interest
payable on the Notes held by the Preferred Trustee. Distributions in arrears for
more than one quarter (and interest thereon) will bear interest thereon
compounded quarterly at the Distribution Rate (to the extent permitted by
applicable law). The term "Distributions," as used herein, includes such cash
distribution and any such interest payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Notes held by the Preferred Trustee and to the extent the Preferred Trustee
has funds on hand in the Payment Account legally available therefor.

                Distributions on the Preferred Securities will accumulate from
the most recent date to which Distributions have been paid or, if no
Distributions have been paid, from June 6, 2001 and will be payable quarterly in
arrears on March 15, June 15, September 15 and December 15, of each year,
commencing on September 15, 2001. Distributions will be computed on the basis of
a 360-day year constituting twelve 30-day months and, for any period of less
than a full calendar month, the number of days elapsed in such month. Under the
terms and conditions of, and in the circumstances set forth in, the Registration
Rights Agreement referred to in the Declaration, Liquidated Damages (as defined
in such Registration Rights Agreement) may be payable in respect of the
Preferred Securities.

                The Company Trustees shall, at the direction of all of the
Holders of the Common Securities, at any time terminate the Trust and, after
satisfaction of liabilities to creditors of the Trust, cause the Notes to be
distributed by the Preferred Trustee to the holders of the Preferred Securities
in liquidation of the Trust as provided in the Declaration.

                The Preferred Securities shall be redeemable as provided in the
Declaration.

                This certificate relates to [_________] aggregate Liquidation

                        (i) at the time the buy order was originated, the
                Transferee was outside the United States or the Owner and any
                person acting on its behalf reasonably believed that the
                Transferee was outside the United States, or

                        (ii) the transaction is being executed in, on or through

                prearranged with a buyer in the United States;

                (D) no directed selling efforts have been made in the United

effected in accordance with the applicable amount, manner of sale and notice
requirements of Rule 144; or

                (H) the transfer is occurring after the second anniversary of
the latest original issue date for the Preferred Securities (including any
issued after the initial offering, unless the Trust determines otherwise) and
the Owner is not, and during the preceding three months has not been, an
