event later than the Effectiveness Deadline, a Shelf Registration Statement
relating to the offer and sale of the Securities by the Holders from time to
time in accordance with the methods of distribution elected by such Holders and
set forth in such Shelf Registration Statement; provided, however, that no
Holder (other than a Purchaser) shall be entitled to have the Securities held by
it covered by such Shelf Registration Statement unless such Holder agrees in
writing to be bound by all the provisions of this Agreement applicable to such
Holder.

                (b)     The Trust and the Company shall each use its best
efforts

                        (i)     to keep the Shelf Registration Statement
                continuously effective in order to permit the Prospectus
                included therein to be lawfully delivered by the Holders of the
                relevant Securities, for a period of two years (or for such

                being called the "Shelf Registration Period"):

                        (A) when all the Preferred Securities covered by the

                        the Shelf Registration Statement have been sold pursuant
                        to the Shelf Registration Statement, or

                        Debentures that had not been sold pursuant to the Shelf
                        Registration Statement have been sold pursuant to the
                        Shelf Registration Statement and

<PAGE>   7

                        (ii)    during the Shelf Registration Period, promptly
                upon the request of any Holder to take any action reasonably
                necessary to register the sale of any Securities of such Holder
                and to identify such Holder as a selling securityholder.

                The Trust and the Company shall be deemed not to have used their
best efforts to keep the Shelf Registration Statement effective during the Shelf
Registration Period if they voluntarily take any action that would result in
Holders of Securities covered thereby not being able to offer and sell such
Securities during such period, unless such action is required by applicable law.

                (c)     Notwithstanding any provisions of this Agreement to the
contrary, the Trust and the Company shall cause the Shelf Registration Statement
and the related Prospectus and any amendment or supplement thereto, as of the
effective date of the Shelf Registration Statement, amendment or supplement, (i)
to comply in all material respects with the applicable requirements of the
Securities Act and the rules and regulations of the Commission and (ii) not to
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading.

        3.      REGISTRATION PROCEDURES. In connection with any Shelf
Registration Statement, the following provisions shall apply:

                (a)     The Trust and the Company shall furnish to (i) the
Purchasers, and (ii) any other Holders who so request, and their respective
counsel and accountants, prior to the filing thereof with the Commission, a copy
of any Shelf Registration Statement, and each amendment thereof and each
amendment or supplement, if any, to the Prospectus included therein and shall
each use its best efforts to reflect in each such document, when so filed with
the Commission, such comments as the Purchasers and such other Holders
reasonably may propose.

                (b)     The Trust and the Company shall give written notice to
the Purchasers and the Holders:

                        (i)     when the Shelf Registration Statement and any
                amendment thereto has been filed with the Commission and when
                the Shelf Registration Statement or any post-effective amendment
                thereto has become effective; and

                                       7
<PAGE>   8

                        (ii)    of any written request by the Commission for
                amendments or supplements to the Shelf Registration Statement or
                the Prospectus included therein or for additional information;

                        (iii)   of the issuance by the Commission of any stop
                order suspending the effectiveness of the Shelf Registration
                Statement or the initiation of any proceedings for that purpose;

                        (iv)    of the receipt by the Trust or the Company of
                any notification with respect to the suspension of the
                qualification of the Securities included therein for sale in any
                state or the initiation or threatening of any proceeding for
                such purpose; and

                        (v)     of the happening, during the Shelf Registration
                Period, of any event that requires the making of any changes in
                the Shelf Registration Statement or the Prospectus so that, as
                of such date, the Registration Statement and the Prospectus do
                not contain an untrue statement of a material fact and do not
                omit to state a material fact required to be stated therein or
                necessary to make the statements therein (in the case of the
                Prospectus, in light of the circumstances under which they were
                made) not misleading (which advice shall be accompanied by an
                instruction to suspend the use of the Prospectus until the
                requisite changes have been made).

                (c)     Each of the Trust and the Company shall use its best
efforts to prevent the issuance, and if issued to obtain the withdrawal, of any
order suspending the effectiveness of any Shelf Registration Statement at the
earliest possible time.

                (d)     The Trust and the Company shall furnish to each
Purchaser and each requesting Holder of Securities included within the coverage
of any Shelf Registration Statement, without charge, at least one copy of such
Shelf Registration Statement and any post-effective amendment thereto
(including, to any such Purchaser or Holder who so requests, any reports or
other documents incorporated therein by reference), including financial
statements and schedules included therein, and, if such Holder so requests, all
exhibits (including those incorporated by reference).

                                       8
<PAGE>   9

                (e)     The Trust and the Company shall, during the Shelf
Registration Period, deliver to each Holder of Securities included within the
coverage of any Shelf Registration Statement, without charge, as many copies of
the Prospectus (including each preliminary Prospectus) included in such Shelf
Registration Statement and any amendment or supplement thereto as such Holder
may reasonably request; and each of the Trust and the Company consents to the
use, in accordance with the terms of this Agreement, of the Prospectus or any
amendment or supplement thereto by each of the selling Holders of Securities in
connection with the offering and sale of the Securities covered by the
Prospectus or any amendment or supplement thereto during the Shelf Registration
Period.

                (f)     Prior to any offering of Securities pursuant to any
Shelf Registration Statement, the Trust and the Company shall register or
qualify, or shall cooperate with the Holders of Securities included therein and
their respective counsel in connection with the registration or qualification
of, such Securities for offer and sale under the securities or blue sky laws of
such states as any such Holders reasonably request in writing and do any and all
other acts or things necessary or advisable to enable the offer and sale in such
states of the Securities covered by such Shelf Registration Statement; provided,
however, that neither the Trust nor the Company will be required to qualify
generally to do business in any jurisdiction where it is not then so qualified
or to take any action which would subject it to general service of process or to
taxation in any such jurisdiction where it is not then so subject.

                (g)     Unless the applicable Securities shall be in book-entry
only form, the Trust and the Company shall cooperate with the Holders of
Securities to facilitate the timely preparation and delivery of certificates
representing Securities to be sold pursuant to any Shelf Registration Statement
free of any restrictive legends and in such permitted denominations and
registered in such names as Holders may request in connection with the sale of
Securities pursuant to such Shelf Registration Statement.

                (h)     Upon the occurrence of any event contemplated by
paragraphs (ii) through (v) of Section 3(b) above (other than a request by the
Commission solely for additional information as referred to in Section 3(b)(ii)
and unless directed otherwise by the Commission), the Trust and the Company
shall promptly prepare and file a post-effective amendment to any Shelf
Registration Statement or an amendment or supplement to the related Prospectus
or file any other required document so that, as thereafter delivered to Holders
or purchasers of the Securities included therein, the Prospectus will not
contain an untrue statement of a material

                                       9
<PAGE>   10

fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading. If the Company or the Trust notifies
the Purchasers or the Holders of the Securities in accordance with paragraphs
(ii) through (v) of Section 3(b) above to suspend the use of the Prospectus
until the requisite changes to the Prospectus have been made, then the
Purchasers and the Holders of the Securities shall suspend use of the Prospectus
for such time.

                (i)     Not later than the effective date of any Shelf
Registration Statement hereunder, the Trust and the Company shall provide a
CUSIP number for the Preferred Securities (and, in the event of and at the time
of any distribution thereof to Holders, the Debentures,) registered under such
Shelf Registration Statement, and provide the applicable Trustee with
certificates for such Securities, in a form eligible for deposit with The
Depository Trust Company.

                (j)     The Trust and the Company shall use their best efforts
to comply with all applicable rules and regulations of the Commission and shall
make generally available to their security holders (or otherwise provide in
accordance with Section 11(a) of the Securities Act) as soon as practicable
after the effective date of the applicable Shelf Registration Statement an
earnings statement satisfying the provisions of Section 11(a) of the Securities
Act, but in no event later than 45 days after the end of a 12-month period (or
90 days, if such period is a fiscal year) beginning with the first month of the
Company's first fiscal quarter commencing after the effective date of the
Registration Statement, which statement shall cover such 12-month period.

                (k)     The Trust and the Company shall cause the Indenture, the
Declaration and the Guarantee to be qualified under the Trust Indenture Act in a
timely manner and containing such changes, if any, as shall be necessary for
such qualification. In the event that such qualification would require the
appointment of a new trustee under the Indenture, Declaration or Guarantee, the
Company or Trust (as applicable) shall appoint a new trustee thereunder pursuant
to the applicable provisions of such agreement.

                (1)     The Trust and the Company may require each Holder of
Securities to be sold pursuant to any Shelf Registration Statement as a
condition to the registration of such Holder's Securities thereunder to furnish
to the Trust and the Company such information regarding the Holder and the
distribution of such Securities as the Trust and the Company may from time to
time reasonably require

                                       10
<PAGE>   11

for inclusion in such Shelf Registration Statement. Each Holder who offers and
sells Securities by means of the Shelf Registration Statement shall do so in
accordance with the terms thereof and the requirements of the Securities Act.

                (m)     The Trust and the Company shall, if requested, promptly
incorporate in a Prospectus supplement or post-effective amendment to a Shelf
Registration Statement, such information as the Managing Underwriters, if any,
reasonably agree should be included therein and to which the Trust and the
Company do not reasonably object and shall make all required filings of such
Prospectus supplement or post-effective amendment as soon as practicable after
they are notified of the matters to be incorporated in such Prospectus
supplement or post-effective amendment.

                (n)     The Trust and the Company shall enter into such
customary agreements (including underwriting agreements in customary form) to
take all other appropriate actions in order to expedite or facilitate the
registration or the disposition of the Securities, and in connection therewith,
if an underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures substantially identical to those set
forth in Section 5 hereof (or such other customary provisions and procedures
acceptable to the Managing Underwriters, if any) with respect to all parties to
be indemnified pursuant to Section 5 hereof.

                (o)     The Trust and the Company shall (i) make reasonably
available for inspection by the Holders of Securities to be registered
thereunder, any underwriter participating in any disposition pursuant to such
Shelf Registration Statement, and any attorney, accountant or other agent
retained by such Holders or any such underwriter, all relevant financial and
other records, pertinent corporate documents and properties of the Trust and the
Company and its subsidiaries as shall be requested in connection with the
discharge of their due diligence obligations; (ii) cause the Company's officers,
directors, employees and independent public accountants and any relevant
Trustees to supply at the Company's expense all relevant information reasonably
requested by such Holders or any such underwriter, attorney, accountant or agent
in connection with any such Shelf Registration Statement as is customary for
similar due diligence examinations; provided, however, that any information that
is designated in writing by the Trust and the Company in good faith as
confidential at the time of delivery of such information shall be kept
confidential by such Holders or any such underwriter, attorney, accountant or
agent, unless such disclosure is made in connection with a court proceeding or
required by law, or such information becomes available to the public generally
or through a third party

                                       11
<PAGE>   12

without an accompanying obligation of confidentiality; and provided further that
the foregoing inspection and information gathering shall be coordinated on
behalf of the Holders and the other parties entitled thereto by one counsel who
shall be Skadden, Arps, Slate, Meagher & Flom LLP unless another
nationally-recognized law firm with specialization in securities laws shall be
chosen by the Company; (iii) make such representations and warranties to the
Holders of Securities registered thereunder and the underwriters, if any, in
form, substance and scope as are customarily made by the issuers to underwriters
in primary underwritten offerings and covering matters as are customarily
covered in representations and warranties requested in primary underwritten
offerings including, but not limited to, those set forth in the Purchase
Agreement; (iv) obtain opinions of counsel to the Trust and the Company and
updates thereof (which counsel and opinions (in form, scope and substance) shall
be reasonably satisfactory to the Managing Underwriters, if any) addressed to
each selling Holder and the underwriters, if any, thereof and dated, in the case
of the initial opinion, the effective date of such Shelf Registration Statement
(it being agreed that the matters to be covered by such opinion shall include,
without limitation, the due incorporation and good standing of the Trust, the
Company and its Subsidiaries; the due authorization, execution and delivery of
the relevant agreement of the type referred to in Section 3(n) hereof; the due
authorization, execution, authentication and issuance, and the validity and
enforceability, of the applicable Securities; the absence of material legal or
governmental proceedings involving the Trust, the Company and its Subsidiaries;
the absence of governmental approvals required to be obtained in connection with
the Shelf Registration Statement, the offering and sale of the applicable
Securities, or any agreement of the type referred to in Section 3(n) hereof; the
compliance as to form of such Shelf Registration Statement and any documents
incorporated by reference therein and of the Indenture, the Declaration and the
Guarantee with the requirements of the Securities Act and the Trust Indenture
Act; and, as of the date of the opinion and as of the effective date of the
Shelf Registration Statement or most recent post-effective amendment thereto, as
the case may be, that such counsel do not believe that such Shelf Registration
Statement and the prospectus included therein, as then amended or supplemented,
and any documents incorporated by reference therein contain an untrue statement
of a material fact or omit to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading (in
the case of any such documents, in the light of the circumstances existing at
the time that such documents were filed with the Commission under the Exchange
Act); (v) cause its officers to execute and deliver all customary documents and
certificates and updates thereof requested by such Holders and any underwriters
of the applicable Securities and (vi) cause its independent public accountants
and the independent public accountants

                                       12

with respect to any other entity for which financial information is provided in
the Shelf Registration Statement to provide to the Holders of the applicable
Securities and any underwriter therefor a comfort letter in customary form and
covering matters of the type customarily covered in comfort letters in
connection with primary underwritten offerings, subject to receipt of
appropriate documentation as contemplated, and only if permitted, by Statement
of Auditing Standards No. 72. The foregoing actions set forth in clauses (iii),
(iv), (v) and (vi) of this Section 3(o) shall be performed at (A) the
effectiveness of such Shelf Registration Statement and each post-effective
amendment thereto and (B) each closing under any underwritten offering of the
Securities to the extent required under any related underwriting or similar
agreement.

                (p)     Each of the Trust and the Company will use its best
efforts to cause the Common Stock relating to such Shelf Registration Statement
to be listed on each securities exchange, over-the-counter market, or respective
counterpart if any, on which any shares of Common Stock are then listed.

                (q)     The Trust and the Company shall, in the event that any
broker-dealer registered under the Exchange Act shall underwrite any Securities
or participate as a member of an underwriting syndicate or selling group or
"assist in the distribution" (within the meaning of the Rules of Fair Practice
and the By-Laws of the National Association of Securities Dealers, Inc.
("NASD")) thereof, whether as a Holder of such Securities or as an underwriter,
a placement or sales agent or a broker or dealer in respect thereof, or
otherwise, assist such broker-dealer in complying with the requirements of such
Rules and By-Laws, including, without limitation, by (A) if such Rules or
By-Laws, including Rule 2720, shall so require, engaging a "qualified
independent underwriter" (as defined in Rule 2720) to participate in the
preparation of the Shelf Registration Statement relating to such Securities, to
exercise usual standards of due diligence in respect thereto and, if any portion
of the offering contemplated by such Shelf Registration Statement is an
underwritten offering or is made through a placement or sales agent, to
recommend the yield of such Securities, (B) indemnifying any such qualified
independent underwriter to the extent of the indemnification of underwriters
provided in Section 5 hereof and (C) providing such information to such
broker-dealer as may be required in order for such broker-dealer to comply with
the requirements of the Rules of Fair Practice of the NASD.

                (r)     The Trust and the Company shall use their best efforts
to take all other steps necessary to effect the registration, offering and sale
of the Securities covered by the Shelf Registration Statement contemplated
hereby.

        4.      REGISTRATION EXPENSES. (a) All expenses incident to the
Company's and the Trust's performance of and compliance with this Agreement will
be borne by the Company, regardless of whether a Shelf Registration Statement is
ever filed or becomes effective, including without limitation;

                        (i)     all registration and filing fees and expenses;

                        (ii)    all fees and expenses of compliance with federal
                securities and state "blue sky" or securities laws;

                        (iii)   all expenses of printing (including printing
                certificates for the Securities without the Restrictive Legend
                to be issued and printing of Prospectuses), messenger and
                delivery services and telephone;

                        (iv)    all fees and disbursements of counsel for the
                Company and the Trust;

                        (v)     all application and filing fees in connection
                with listing the Securities on a national securities exchange or
                automated quotation system pursuant to the requirements
                hereof; and

                        (vi)    all fees and disbursements of independent
                certified public accountants of the Company and the Trust
                (including the expenses of any special audit and comfort letters
                required by or incident to such performance).

                The Company and the Trust will bear their internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expenses of any annual
audit and the fees and expenses of any person, including special experts,
retained by the Company or the Trust.

                (b)     In connection with any Shelf Registration Statement
required by this Agreement, the Company and the Trust will reimburse the
Purchasers and the Holders who are selling or reselling Securities pursuant to
the Shelf Registration Statement for the reasonable fees and disbursements of
not more than one counsel, who shall be Skadden, Arps, Slate, Meagher & Flom LLP
unless another nationally-

                                       14
<PAGE>   15

recognized law firm with specialization in securities laws shall be chosen by
the Company.

        5.      INDEMNIFICATION AND CONTRIBUTION. (a) In connection with any
Shelf Registration Statement, the Trust and the Company, jointly and severally,
agree to indemnify and hold harmless the Purchasers, each Holder of Securities
covered thereby (including the Purchasers), their respective partners,
directors, and officers and each person, if any, who controls the Purchasers or
any such Holder within the meaning of Section 15 of the Securities Act (each
Purchaser, Holder and such controlling persons are referred to collectively as
the "Indemnified Parties") against any losses, claims, damages or liabilities,
joint or several, or any actions in respect thereof (including, but not limited
to, any losses, claims, damages, liabilities or actions relating to purchases
and sales of the Securities) to which each Indemnified Party may become subject
under the Securities Act, the Exchange Act or other Federal or state statutory
law or regulation, at common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in the Shelf Registration Statement as originally filed or in any
amendment or supplement thereof, or in any preliminary Prospectus or Prospectus,
or in any amendment thereof or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in the light of the circumstances under which they were made, and shall
reimburse each such Indemnified Party, as incurred, for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that (i) the Company and the Trust will not be liable in any case to the extent
that any such loss, claim, damage or liability arises out of or is based upon
any such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of the Purchasers or any
such Holder specifically for inclusion therein and (ii) the foregoing indemnity,
with respect to any untrue statement or alleged untrue statement or omission or
alleged omission made in any preliminary Prospectus relating to a Shelf
Registration Statement, shall not inure to the benefit of any Holder (or any
person controlling such Holder) from whom the person asserting any such losses,
claims, damages or liabilities purchased the Securities concerned, to the extent
that a Prospectus relating to such Securities was required to be delivered by
such Holder under the Securities Act in connection with such purchase and any
such loss, claim, damage or liability of such Holder results from the fact that
there was not sent or given to such person, at or

                                       15
<PAGE>   16

prior to the written confirmation of the sale of such Securities to such person,
a copy of the final Prospectus if the Company had previously furnished copies
thereof to such Holder at or prior to the written confirmation of the sale of
such Securities to such person and the untrue statement or alleged untrue
statement or omission or alleged omission contained in the preliminary
prospectus was corrected in the final prospectus (or the final prospectus as
supplemented). This indemnity agreement will be in addition to any liability
which the Company or the Trust may otherwise have.

                The Trust and the Company, jointly and severally, shall also
indemnify underwriters, their officers, directors and each person who controls
such underwriters within the meaning of the Securities Act or the Exchange Act
to the same extent as provided above with respect to the indemnification of the
Holders of the Securities and shall, if requested by any Holder, enter into an
underwriting agreement reflecting such agreement, as provided in Section 3(n)
and Section 6 hereof.

                (b)     Each Holder of Securities covered by a Shelf
Registration Statement (including the Purchasers) severally, and not jointly,
agrees to indemnify and hold harmless (i) the Trust and the Company, (ii) each
of the directors of the Company, (iii) each of its officers who signs such Shelf
Registration Statement and (iv) each person who controls the Trust or the
Company within the meaning of either the Securities Act or the Exchange Act to
the same extent as the foregoing indemnity from the Trust and the Company, but
only in respect of written information relating to such Holder furnished to the
Company by or on behalf of such Holder specifically for inclusion in the
documents referred to in the foregoing indemnity. This indemnity agreement will
be in addition to any liability which any such Holder may otherwise have.

                (c)     Promptly after receipt by an indemnified party under
this Section 5 of notice of the commencement of any action or proceeding
(including a governmental investigation), such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 5, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve the indemnifying
party from any liability it may have to any indemnified party otherwise than
under paragraph (a) or (b) above. In case any such action is brought against any
indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with

                                       16
<PAGE>   17

counsel reasonably satisfactory to such indemnified party (who shall not, except
with the consent of such indemnified party, be counsel to the indemnifying
party), and after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party will
not be liable to such indemnified party under this Section 5 for any legal or
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof other than reasonable costs of investigation. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened action in respect of
which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party unless such settlement
includes an unconditional release of such indemnified party from all liability
on any claims that are the subject matter of such action and does not include a
statement as to or an admission of fault, culpability or a failure to act by or
on behalf of any indemnified party.

                (d)     If the indemnification provided for in this Section 5 is
unavailable or insufficient to hold harmless an indemnified party under
subsections (a) or (b) above, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to in
subsection (a) or (b) above (i) in such proportion as is appropriate to reflect
the relative benefits received by the indemnifying party or parties on the one
hand and the indemnified party on the other from the Initial Placement and the
Shelf Registration Statement, or (ii) if the allocation provided by the
foregoing clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the indemnifying party or parties on
the one hand and the indemnified party on the other in connection with the
statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof) as well as any other relevant
equitable considerations. The relative fault of the parties shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Trust or the Company on
the one hand or such Holder or such other indemnified party, as the case may
be, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid by an indemnified party as a result of the losses, claims,
damages or liabilities referred to in the first sentence of this subsection(d)
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any action
or claim which is the subject

                                       17
<PAGE>   18

of this subsection(d). Notwithstanding any other provision of this Section
5(d), the Holders of the Securities shall not be required to contribute any
amount in excess of the amount by which the net proceeds received by such
Holders from the sale of the Securities pursuant to the Shelf Registration
Statement exceeds the amount of damages which such Holders have otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this paragraph (d), each person, if any, who
controls such indemnified party within the meaning of the Securities Act or the
Exchange Act shall have the same rights to contribution as such indemnified
party and each person, if any, who controls the Trust or the Company within the
meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Trust and the Company.

                (e)     The agreements contained in this Section 5 shall survive
the sale of the Securities pursuant to a Registration Statement and shall remain
in full force and effect, regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of any indemnified party.

        6.      UNDERWRITTEN OFFERING. If, pursuant to written notice delivered
to the Company by the Holders of a majority in aggregate liquidation amount of
the Preferred Securities, a majority in aggregate principal amount of the
Debentures or a majority of holders of the Common Stock, as the case may be,
registered pursuant to a Shelf Registration, such Holders so elect, the offer
and sale of any such Preferred Securities, Debentures and/or Common Stock may be
effected in the form of an underwritten offering. In any such underwritten
offering, the investment banker or bankers and manager or managers that will
administer the offering will be selected by, and the underwriting arrangements
with respect thereto will be approved by, the Company; provided, however, that
such investment bankers and managers and underwriting arrangements must be
reasonably satisfactory to the Holders of a majority of the Securities to be
included in such offering. No Holder may participate in any underwritten
offering contemplated hereby unless such Holder (a) agrees to sell such Holder's
Securities in accordance with any approved underwriting arrangements, and (b)
completes and executes all reasonable questionnaires, powers of attorney,
indemnities, underwriting agreements, lock-up letters and other documents
required under the terms of such approved underwriting arrangements.

        7.      CHANGES TO THE APPLICABLE RATE UNDER CERTAIN CIRCUMSTANCES.
(a) The Applicable Rate at which interest is paid on the Debentures (including
in respect of amounts accruing during any Deferral Period), and distributions
are paid on the Preferred Securities shall be adjusted as follows, if any of the
following events occur (each such event in clauses (i) through (iii) below, a
"Registration Default"):

                        (i)     if a Shelf Registration Statement is not filed
                with the Commission on or prior to the Filing Deadline;

                        (ii)    if the Shelf Registration Statement is not
                declared effective by the Commission on or prior to the
                Effectiveness Deadline;

                        (iii)   if (A) after the Shelf Registration Statement is
                declared effective, such Shelf Registration Statement ceases to
                be effective prior to the end of the Shelf Registration Period
                or (B) such Shelf Registration Statement or the related
                Prospectus ceases to be usable in connection with resales of
                Securities covered by such Shelf Registration Statement prior to
                the end of the Shelf Registration Period because either (1) any
                event occurs as a result of which the related Prospectus forming
                part of such Shelf Registration Statement would include any
                untrue statement of a material fact or omit to state any
                material fact necessary to make the statements therein in the
                light of the circumstances in which they were made not
                misleading or (2) it shall be necessary to amend such Shelf
                Registration Statement, or supplement the related Prospectus, to
                comply with the Securities Act or the Exchange Act or the
                respective rules thereunder.

                Each of the foregoing will constitute a Registration Default
whatever the reason for any such event and whether it is voluntary or
involuntary or is beyond the control of the Company or pursuant to operation of
law or as a result of any action or inaction by the Commission.

                Additional Interest shall accrue on the Securities over and
above the interest set forth in the title of the Securities from and including
the date on which any such Registration Default shall occur to but excluding the
date on which all such Registration Defaults have been cured, at a rate of 0.50%
per annum (the "Additional Interest Rate"). The increase in the Applicable Rate
attributable to any Registration Default shall cease to be effective from the
date such Registration Default is cured,

                                       19
<PAGE>   20

and the Applicable Rate shall be reduced at such time to the Applicable Rate in
effect immediately prior to such Registration Default; provided, however, in the
event a Registration Default occurs prior to the Reset Date and is cured on or
after the Reset Date, the Applicable Rate shall be the Term Rate from the date
such Registration Default is cured.

                (b)     A Registration Default referred to in Section 7(a)(iii)
shall be deemed not to have occurred and be continuing in relation to the Shelf
Registration Statement or the related Prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Holders to use the related Prospectus or (y) the occurrence of other material
events or developments with respect to the Trust or the Company that would need
to be described in such Registration Statement or the related Prospectus and
(ii) in the case of clause (y), the Trust and the Company are proceeding
promptly and in good faith to amend or supplement such Registration Statement
and related Prospectus to describe such events; provided, however, that in any
case if such Registration Default occurs for a continuous period in excess of 30
days, Additional Interest shall be payable in accordance with the above
paragraph from the day such Registration Default occurred until such
Registration Default is cured.

                (c)     Any amounts of Additional Interest due pursuant to
Section 7(a) will be payable in cash on the regular interest payment dates (or
such other time as provided in the Indenture or Declaration, as applicable, for
the payment of interest or distributions) with respect to the Securities. The
amount of Additional Interest will be determined by multiplying the applicable
Additional Interest Rate by the principal amount of the Securities and further
multiplied by a fraction, the numerator of which is the number of days such
Additional Interest Rate was applicable during such period (determined on the
basis of a 360-day year comprised of twelve 30-day months), and the denominator
of which is 360.

        8.      RULES 144 AND 144A. The Company and the Trust shall use their
best efforts to file the reports required to be filed by them under the
Securities Act and the Exchange Act in a timely manner and, if at any time the
Company or the Trust is not required to file such reports, it will, upon the
request of any Holder of Securities, make publicly available other information
so long as necessary to permit sales of

                                       20
<PAGE>   21

their securities pursuant to Rules 144 and 144A of the Securities Act, or any
successor regulation or statute thereto. The Company and the Trust covenant that
they will take such further action as any Holder of Securities may reasonably
request, all to the extent required from time to time to enable such Holder to
sell Securities without registration under the Securities Act within the
limitation of the exemptions provided by Rules 144 and 144A (including the
requirements of Rule 144A(d)(4)). The Company and the Trust will provide a copy
of this Agreement to prospective purchasers of Securities identified to the
Company or the Trust by the Purchasers upon request. Upon the request of any
Holder of Securities, the Company and the Trust shall deliver to such Holder a
written statement as to whether it has complied with such requirements.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company and the Trust to register any of their securities pursuant
to the Exchange Act.

        9.      MISCELLANEOUS.

                (a)     Remedies. The Company and the Trust each acknowledge and
agree that any failure by either of them to comply with their respective
obligations under Section 2 hereof may result in material irreparable injury to
the Purchasers or the Holders for which there is no adequate remedy at law, that
it will not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Purchasers or any Holder may obtain such
relief as may be required to specifically enforce the Company's and the Trust's
obligations under Section 2 hereof. The Company and the Trust each further agree
to waive the defense in any action for specific performance of Section 2 hereof
that a remedy at law would be adequate.

                (b)     No Inconsistent Agreements. The Trust and the Company
have not, as of the date hereof, entered into, nor shall they on or after the
date hereof, enter into, any agreement with respect to their securities or
otherwise that is inconsistent with the rights granted to the Holders herein or
otherwise conflicts with the provisions hereof.

                (c)     Amendments and Waivers. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
qualified, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, unless the Trust and the Company have
obtained the written consent of a majority in principal amount, liquidation
preference or voting rights (as applicable ) of the Securities affected by such
amendment, qualification, modification, supple-

                                       21

ment, waiver or consent.

                (d)     Notices. All notices and other communications provided
for or permitted hereunder shall be made in writing and shall be mailed,
delivered, telegraphed and confirmed or faxed and confirmed:

                (1)     if to a Holder, at the most current address given by
        such Holder to the Company in accordance with the provisions of this
        Section 9(d), which address initially is, with respect to each Holder,
        the address of such Holder maintained by the Registrar under the
        Indenture, with respect to the Debentures; or the Declaration, with
        respect to the Preferred Securities; with a copy in a like manner to
        Credit Suisse First Boston Corporation;

                (2)     if to any or all of the Purchasers, initially at the
        address set forth in the Purchase Agreement; and

                (3)     if to the Trust or the Company, initially at its address
        set forth in the Purchase Agreement.

                Any Purchaser, any Holder, the Trust or the Company by notice to
the other may designate additional or different addresses for subsequent notices
or communications (including with respect to any Holder, by means of any Selling
Holders Questionnaire delivered by such Holder to the Trust and the Company).

                (e)     Third Party Beneficiaries. The Holders shall be third
party beneficiaries to the agreements made hereunder between the Company and/or
the Trust, on the one hand, and the Purchasers, on the other hand, and shall
have the right to enforce such agreements directly to the extent they may deem
such enforcement necessary or advisable to protect their rights or the rights of
Holders hereunder.

                (f)     Successors and Assigns. This Agreement shall inure to
the benefit of and be binding upon the successors and assigns of each of the
parties and the Holders, including, without the need for an express assignment
or any consent by the Trust or the Company thereto, subsequent Holders of
Securities. The Trust and the Company hereby agree to extend the benefits of
this Agreement to any Holder of Securities and any such Holder may specifically
enforce the provisions of this Agreement as if an original party hereto.

                (g)     Counterparts, This Agreement may be executed in any

      Majority represents of the aggregate principal amount of the Debentures
      outstanding;

      provided further, each Holder of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until the effects of all Events of

            (ii) acquire any assets other than as expressly provided herein;

                                       19

      or the Debentures where such consent shall be required unless, in the case
      of each action described in clause (A), (B), (C) or (D), the Trust shall
      have received an opinion of a nationally recognized independent counsel
      experienced in such matters to the effect that such modification will not
      cause more than an insubstantial risk that for United States federal
      income tax purposes the Trust will not be classified as a grantor trust.

      Section 3.08 Powers and Duties of the Property Trustee. (a) The legal
title to the Debentures shall be owned by and held of record in the name of the
Property Trustee in trust for the benefit of the Holders of the Securities. The
right, title and interest of the Property Trustee to the Debentures shall vest
automatically in each Person who may hereafter be appointed as Property Trustee
in accordance with Section 5.06. To the fullest extent permitted by law, such
vesting and cessation of title shall be effective whether or not conveyancing
documents with regard to the Debentures have been executed and delivered.

      (b) The Property Trustee shall not transfer its right, title and interest
in the Debt to the Administrative Trustees or to the Delaware Trustee (if the
Property Trustee does not also act as Delaware Trustee).

      (c) The Property Trustee shall:

            (i) establish and maintain a segregated non-interest bearing trust
      account (the "Property Trustee Account") in the name of and under the
      exclusive control of the Property Trustee on behalf of the Holders of the
      Securities and, upon the receipt of payments of funds made in respect of
      the Debentures held by the Property Trustee, deposit such

                                       20
<PAGE>   26
funds into the Property Trustee Account and make payments to the Holders of the
Preferred Securities and Holders of the Common Securities from the Property
Trustee Account in accordance with Section 6.01. Funds in the Property Trustee
Account shall be held uninvested until disbursed in accordance with this
Declaration.

              (ii)   engage in such ministerial activities as so directed and as
shall be necessary or appropriate to effect the redemption of the Preferred
Securities and the Common Securities to the extent the Debentures are redeemed
or mature; and

              (iii)  upon written notice of distribution issued by the
Administrative Trustees in accordance with the terms of the Securities, engage
in such ministerial activities as so directed as shall be necessary or
appropriate to effect the distribution of the Debentures to Holders of
Securities.

       (d)    The Property Trustee shall take all actions and perform such
duties as may be specifically required of the Property Trustee pursuant to the
terms of the Securities.

       (e)    The Property Trustee may take any Legal Action which arises out of
or in connection with an Event of Default or the Property Trustee's duties and
obligations under this Declaration or the Trust Indenture Act; provided,
however, that if a Debenture Event of Default has occurred and is continuing and
such event is attributable to the failure of the Depositor as issuer of the
Debentures to pay interest or principal on the Debentures on the date such
interest or principal is otherwise payable (or in the case of redemption, on the
redemption date), then a Holder of Preferred Securities may institute a legal
proceeding directly, subject to the terms of the Indenture (including the
subordination provisions set forth in Article XII thereof), for enforcement of
payment to such Holder of the principal of or interest on the Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such Holder (a "Direct Action") on or after the respective due
date specified or provided for in the Securities. In connection with such Direct
Action, the Holders of the Common Securities will be subrogated to the rights of
such Holder of Preferred Securities to the extent of any payment made by the
Depositor to such Holder of Preferred Securities in such Direct Action. In
addition, if the Property Trustee fails to enforce its rights under the
Debentures (other than rights arising from an Event of Default described in the
immediately preceding sentence) after any Holder of Preferred Securities shall
have made a written request to the property trustee to enforce such rights, such
Holder of Preferred Securities may, to the fullest extent permitted by law,
institute a direct action to enforce the rights of the Trustee or any other
Person. Except as provided in the preceding sentences, the Holders of Preferred
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures.

       (f)    The Property Trustee shall not resign as a Trustee unless either:

                                       21

<PAGE>   27

              (i)    the Trust has been completely liquidated and the proceeds
of the liquidation distributed to the Holders of Securities pursuant to the
terms of the Securities; or

              (ii)   a Successor Property Trustee has been appointed and has
accepted that appointment in accordance with Section 5.06.

       (g)    The Property Trustee shall have the legal power to exercise all of
the rights, powers and privileges of a holder of Debentures under the Indenture
and, if an Event of Default occurs and is continuing, the Property Trustee may,
for the benefit of Holders of the Securities, enforce its rights as holder of
the Debentures subject to the rights of the Holders pursuant to the terms of the
Securities and this Declaration.

       (h)    The Property Trustee shall act as the initial Paying Agent and
Registrar to pay Distributions, redemption payments or liquidation payments on
behalf of the Trust with respect to all Securities and any such Paying Agent
shall comply with Section 317(b) of the Trust Indenture Act. Any Paying Agent
may be removed by the Administrative Trustees at any time and a successor Paying
Agent or additional Paying Agents may be appointed at any time by the
Administrative Trustees. The Paying Agent may resign upon 30 days' written
notice to the Property Trustee, the Administrative Trustees and the Depositor.

       (i)    Subject to this Section 3.08, the Property Trustee shall have none
of the duties, liabilities, powers or the authority of the Administrative
Trustees set forth in Section 3.06.

              The Property Trustee trust exercise the powers set forth in this
Section 3.08 in a manner that is consistent with the purposes and functions of
the Trust set out in Section 3.03, and the Property Trustee shall not take any
action that is inconsistent with the purposes and functions of the Trust set out
in Section 3.03.

              Section 3.09 Certain Duties and Responsibilities of the Proper
Trustee. (a) The Property Trustee, before the occurrence of any Event of Default
and after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Declaration and no implied covenants shall be read into this Declaration against
the Property Trustee. In case an Event of Default has occurred (that has not
been cured or waived pursuant to Section 2.06), the Property 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, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

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

              (i)    prior to the occurrence of an Event of Default and after
       the curing or waiving of all such Events of Default that may have
       occurred:

<PAGE>   28

                     (A)    the duties and obligations of the Property Trustee
              shall be determined solely by the express provisions of this
              Declaration and in the Securities and the Property Trustee shall
              not be liable except for the performance of such duties and
              obligations as are specifically set forth in this Declaration and
              in the Securities, and no implied covenants or obligations shall
              be read into this Declaration or the Securities against the
              Property Trustee; and

                     (B)    in the absence of bad faith on the part of the
              Property Trustee, the Property Trustee may conclusively rely, as
              to the truth of the statements and the correctness of the opinions
              expressed therein, upon any certificates or opinions furnished to
              the Property Trustee and conforming to the requirements of this
              Declaration; but in the case of any such certificates or opinions
              that by any provision hereof are specifically required to be
              furnished to the Property Trustee, the Property Trustee shall be
              under a duty to examine the same to determine whether or not they
              conform to the requirements of this Declaration (but need not
              confirm or investigate the accuracy of mathematical calculations
              or other facts stated therein);

              (ii)   the Property Trustee shall not be liable for any error of
       judgment made in good faith by a Responsible Officer of the Property
       Trustee, unless it shall be proved that the Property Trustee was
       negligent in ascertaining the pertinent facts;

              (iii)  the Property 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 Securities relating to the time, method and
       place of conducting any proceeding for any remedy available to the
       Property Trustee, or exercising any trust or power conferred upon the
       Property Trustee under this Declaration;

              (iv)   no provision of this Declaration shall require the Property
       Trustee to expend or risk its own funds or otherwise incur personal
       financial liability in the performance of any of its duties or in the
       exercise of any of its rights or powers;

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

              (vi)   the Property Trustee shall have no duty or liability for or
       with respect to the value, genuineness, existence or sufficiency of

                                       23

       the Debentures or the payment of any taxes or assessments levied thereon
       or in connection therewith;

              (vii)  the Property Trustee shall not be liable for any interest
       on any money received by it except as it may otherwise agree with the
       Depositor. Money held by the Property Trustee need not be segregated from
       other funds held by it except in relation to the Property Trustee Account
       maintained by the Property Trustee pursuant to Section 3.08(c)(i) and
       except to the extent otherwise required by law; and

              (viii) the Property Trustee shall not be responsible for
       monitoring the compliance by the Administrative Trustees or the Depositor
       with their respective duties under this Declaration, nor shall the
       Property Trustee be liable for the default or misconduct of the
       Administrative Trustees or the Depositor.

       rely upon an Officers' Certificate which, upon receipt of such request,

       Trustees;

       attorneys' fees and expenses) and liabilities that might be incurred by
       it in complying with such request or direction, including such reasonable
       advances as may be requested in writing by the Property Trustee, provided
       that, nothing contained in this Section 3.10(a)(vi) shall be taken to
       relieve the Property Trustee, upon the occurrence of an Event of Default,
       of its obligation to exercise the rights and powers vested in it by this
       Declaration and use the same degree of care and skill in the exercise
       thereof as a prudent person would exercise or use under the circumstances
       in the conduct of his or her own affairs;

              (vii)  the Property Trustee shall not be bound to make any
       investigation into the facts or matters stated in any resolution,

       attorney appointed with due care by it hereunder;

              (ix)   any action taken by the Property Trustee or its agents
       hereunder shall bind the Trust and the Holders of the Securities, and the
       signature of the Property Trustee or its agents alone shall be sufficient
       and effective to perform any such action and no third party shall be
       required to inquire as to the authority of the property trustee to so act
       or as to its compliance with any of the terms and provisions of this
       declaration both of which shall be conclusively evidenced by the Property
       Trustee's or its agent's taking such action;

              (x)    whenever in the administration of this Declaration the
       Property Trustee shall deem it desirable to receive instructions with
       respect to enforcing any remedy or right or taking any other action
       hereunder the Property Trustee (i) may request instructions from the
       Holders of the Securities which instructions may only be given by the
       Holders of the same proportion in liquidation amount of the Securities as
       would be

                                       25
<PAGE>   31
       entitled to direct the Property Trustee under the terms of the 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;

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

              (xii)  the Property Trustee shall not be liable for any action
       taken, suffered, or omitted to be taken by it in good faith and
       reasonably believed by it to be authorized or within the discretion or
       rights or powers conferred upon it by this Declaration.

       (b)    No provision of this Declaration shall be deemed to impose any
duty or obligation on the Property 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 Property 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 Property Trustee
shall be construed to be a duty.

entitled to exercise any powers, nor shall the Delaware Trustee have any of the
duties and responsibilities of the Administrative Trustees or the Property

shall be signed by a majority of the Administrative Trustees.

       Section 3.13 Not Responsible for Recitals or Issuance of Securities. The

statements of the Depositor, and the Trustees do not assume any responsibility
for their correctness. The Trustees make no representations as to the value or

representations as to the validity or sufficiency of this Declaration, the

       Section 3.15 Mergers. (a) 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 Person, except as
described in Section 3.15(b) and (c) of this Declaration or paragraph 3 of Annex
I.

       (b)    The Trust may, with the consent of a majority of the
Administrative Trustees and without the consent of the Holders of the
Securities, the Delaware Trustee or the Property Trustee, consolidate,
amalgamate, merge with or into, or be replaced by a trust organized as such
under the laws of any State or the District of Columbia; provided that:

              (i)    if the Trust is not the surviving entity, the successor

       entity (the "Successor Entity") either:

                     (A)    expressly assumes all of the obligations of the
              Trust under the Securities; or

                     (B)    substitutes for the Preferred Securities other
              securities having substantially the same terms as the Preferred
              Securities (the "Successor Securities") as long as the Successor
              Securities rank, with respect to participation in the profits and
              Distributions or in the assets of the Successor Entity at least as
              high as the Preferred Securities rank with respect to
              participation in the profits and dividends or in the assets of the
              Trust;

              (ii)   the Debenture issuer expressly acknowledges a trustee of
       the Successor Entity that possesses the same powers and duties as the
       Property Trustee as the Holder of the Debentures;

              (iii)  to the extent the Preferred Securities are listed on any
       national securities exchange or with another organization for listing or
       quotation, the Preferred Securities or any Successor Securities shall be
       so listed, or any Successor Securities will be listed upon notification
       of issuance, on any national securities exchange or with any other
       organization on which the Preferred Securities are then listed or quoted;

              (iv)   such merger, consolidation, amalgamation or replacement
       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 or replacement
       does not adversely affect the powers, preferences and other special
       rights of the Holders of the Preferred Securities (including any
       Successor Securities) in any material respect;

              (vi)   such Successor Entity has a purpose substantially identical
       and limited to that of the Trust;

                                       27
<PAGE>   33

              (vii)  prior to such merger, consolidation, amalgamation or
       replacement, the Depositor has received an opinion of a nationally
       recognized independent counsel (reasonably acceptable to the Property
       Trustee) to the Trust experienced in such matters to the effect that:

                     (A)    following such merger, consolidation, amalgamation
              or replacement, the Trust or the Successor Entity will continue to
              be treated as a grantor trust for United States federal income tax
              purposes;

                     (B)    following such merger, consolidation, amalgamation
              or replacement, neither the Depositor nor the Successor Entity
              will be required to register as an Investment Company;

                     (C)    such merger, consolidation, amalgamation or
              replacement will not adversely affect the limited liability of the
              Holders of the Securities (including any Successor Securities);

              (viii) the Depositor or any permitted successor or assignee
       directly or indirectly owns all the common securities of such successor
       entity and provides a guarantee to the Holders of the Successor
       Securities with respect to the Successor Entity having substantially the
       same terns as the Preferred Securities Guarantee; and

              (ix)   such merger, consolidation, amalgamation, replacement or
       lease is not a taxable event for the Holders of the Preferred Securities.

       (c)    Notwithstanding Section 3.15(b), the Trust shall not, except with
the consent of Holders of 100% in liquidation amount of the 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 or
replacement would cause the Trust or Successor Entity to be classified as other
than a grantor trust for United States federal income tax purposes.

Obligation, under the Preferred Securities Guarantee or under this Agreement for
any reason whatsoever. Such agreement is continuing, irrevocable, unconditional

other Appointment Events cease to be continuing. Any Trustee may resign from
office (without need for prior or subsequent accounting) by an instrument in
writing signed by the Trustee and delivered to the Depositor and the Trust,
which resignation shall take effect upon such delivery or upon such later date
as is specified therein; provided, however, that:

              (i)    No such resignation of the Trustee that acts as the
       Property Trustee shall be effective:

                     (A)    until a Successor Property Trustee has been
              appointed and has accepted such appointment by instrument executed
              by such Successor Property Trustee and delivered to the Trust, the
              Depositor and the resigning Property Trustee; or

                     (B)    until the assets of the Trust have been completely
              liquidated and the proceeds thereof distributed to the Holders of
              the Securities;

              (ii)   no such resignation of the Trustee that acts as the
       Delaware Trustee shall be effective until a Successor Delaware Trustee
       has been appointed and has accepted such appointment by instrument
       executed by such Successor Delaware Trustee and delivered to the Trust,
       the Depositor and the resigning Delaware Trustee; and

              (iii)  no such resignation of a Special Trustee shall be effective
       until the 60th day following delivery of the instrument of resignation of
       the Special Trustee to the Depositor and the Trust or such later date
       specified in such instrument during which period the Holders of the
       Preferred Securities shall have the right to appoint a successor Special
       Trustee as provided in this section 5.06.

       (f) The Holders of the Common Securities shall use their best efforts to
promptly appoint a Successor Property Trustee or Successor Delaware Trustee, as
the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with this Section 5.06 or is removed
pursuant to this Section 5.06.

       (g) If no Successor Property Trustee or Successor Delaware Trustee shall
have been appointed and accepted appointment as provided in this Section 5.06

                                       34
<PAGE>   40
within 60 days after delivery to the Depositor and the Trust of an instrument of
resignation or removal, the resigning Property Trustee or Delaware Trustee,
resigning or being removed as applicable, may petition any court of competent
jurisdiction for appointment of a Successor Property Trustee or Successor
Delaware Trustee. Such court may thereupon, after prescribing such notice, if
any, as it may deem proper and prescribe, appoint a Successor Property Trustee
or Successor Delaware Trustee, as the case may be.

       (h)    No Property Trustee or Delaware Trustee shall be liable for the
acts or omissions to act of any Successor Property Trustee or Successor Delaware
Trustee, as the case may be.

       Section 5.07 Vacancies among Trustees. If a Trustee ceases to hold office
for any reason and the number of Trustees is not reduced pursuant to Section
5.01, or if the number of Trustees is increased pursuant to Section 5.01, a
vacancy shall occur. A resolution certifying the existence of such vacancy by a
majority of the Administrative Trustees shall be conclusive evidence of the
existence of such vacancy. The vacancy shall be filled with a Trustee appointed
in accordance with Section 5.06.

       Section 5.08 Effect of Vacancies. The death, resignation, retirement,
removal, bankruptcy, dissolution, liquidation, incompetence or incapacity to
perform the duties of a Trustee shall not operate to dissolve, terminate or
annul the Trust. Whenever a vacancy in the number of Administrative Trustees
shall occur, until such vacancy is filled by the appointment of a Administrative
Trustee in accordance with Section 5.06, the Administrative Trustees in office,
regardless of their number, shall have all the powers granted to the
Administrative Trustees and shall discharge all the duties imposed upon the
Administrative Trustees by this Declaration.

       Section 5.09 Meetings. Meetings of the Administrative Trustees shall be
held from time to time upon the call of any Administrative Trustee. Regular
meetings of the Administrative Trustees may be held at a time and place fixed by
resolution of the Administrative Trustees. Notice of any meetings of the
Administrative Trustees shall be hand delivered or otherwise delivered in
writing (including by facsimile or overnight courier) not less than 24 hours
before such meeting. Notices shall contain a brief statement of the time, place
and anticipated purposes of the meeting. The presence (whether in person or by
telephone) of an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Declaration, any action of the Administrative
Trustees may be taken at a meeting by vote of a majority of the Administrative
Trustees present (whether in person or by telephone) and eligible to vote with
respect to such matter, provided that a Quorum is present, or without a meeting
and without prior notice by the unanimous written consent of the Administrative
Trustees.

       In the event there is only one Administrative Trustee, any and all action
of such Administrative Trustee shall be evidenced by a written consent of such
Administrative Trustee. In the event a Special Trustee is holding office
pursuant to Section 5.06, such Special Trustee shall have the same rights as an
Administrative Trustee with respect to notice and participation in a meeting of
the Administrative Trustees.

       Section 5.10 Delegation of Power.

       (a)    Any Administrative Trustee may, by power of attorney consistent
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
3.06, including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

       (b)    the Administrative Trustees shall have power to delegate from time
to time to such of their number or to officers of the Trust the doing of such
things and the execution of such instruments either in the name of the Trust or
the names of the Administrative Trustees or otherwise as the Administrative
Trustees may deem expedient, to the extent such delegation is not prohibited by
applicable law or contrary to the provisions of the Trust, as set forth herein.

       Section 5.11 Merger, Conversion, Consolidation or Succession to
Business. Any Person into which the Property Trustee or the Delaware Trustee, as
the case may be, may be merged or converted or with which either may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Property Trustee or the Delaware Trustee, as the case
may be, shall be a party, or any Person succeeding to all or substantially all
the corporate trust business of the Property Trustee or the Delaware Trustee,
as the case may be, shall be the successor of the Property Trustee or the
Delaware Trustee, as the case may be, hereunder, provided such Person 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
other than as required by applicable law.

       Section 5.12 Compensation and Expenses. The Depositor agrees:

       (a)    to pay the Property Trustee and the Delaware Trustee from time to
time such compensation as shall be agreed in writing between the Depositor and
the Property Trustee and the Delaware Trustee, respectively, for all services
rendered by them hereunder (which compensation shall not be limited by any
provision of any law in regard to the compensation of a trustee of an express
trust); and

       (b)    to reimburse the Property Trustee and the Delaware Trustee upon
their request for expenses, disbursements and advances incurred or made by the
Property Trustee or the Delaware Trustee, respectively, in accordance with any
provision of this Declaration (including the reasonable compensation and the
expenses and advances of their agents and counsel and other professionals),
except any such expense or advance as may be attributable to their negligence or
wilfull misconduct.

                                Distributions

       Section 6.01 Distributions. Holders shall receive Distributions in
accordance with the applicable terms of the relevant Holder's Securities.
Distributions shall be made on the Preferred Securities and the Common
Securities in accordance with the preferences set forth in the terms attached as
Annex I hereto. If and to the extent that the Debenture Issuer makes a payment
of interest (including Compounded Interest (as defined in the Indenture) and
Additional Amounts (as defined in the Indenture)), premium and principal on the
Debentures held by the Property Trustee (the amount of any such payment being a
"Payment Amount"), the Property Trustee shall and is directed, to the extent
funds are available for that purpose, to make a distribution (a "Distribution")
of the Payment Amount to Holders.

                                   ARTICLE VII

                             Issuance of Securities

       Section 7.01 General Provisions Regarding Securities.

       (a)    The Administrative Trustees shall on behalf of the Trust issue one
class of convertible preferred securities, designated as Remarketable Term
Income Deferrable Equity Securities (HIGH TIDES)(SM), liquidation amount $50 per
HIGH TIDES, representing undivided beneficial interests in the assets of the
Trust (the "Preferred Securities"), having such terms as are set forth in Annex
I (including as such terms may be modified in accordance with the provisions of
the Remarketing Agreement) and one class of convertible common securities,
liquidation amount $50, representing undivided beneficial interests in the
assets of the Trust (the "Common Securities"), having such terms as are set
forth in Annex I. On the Reset Date and as contemplated by the Remarketing
Agreement, the Trust may also issue securities having Term Provisions to be set
by the Remarketing Agent in accordance with the terms of the Remarketing
Agreement. The Trust shall have no securities or other interests in the assets
of the Trust other than the Preferred Securities and the Common Securities. The
Trust shall issue no Securities in bearer form.

       (b)    The consideration received by the Trust for the issuance of the
Securities shall constitute a contribution to the capital of the Trust and shall
not constitute a loan to the Trust.

       (e)    Upon issuance of the Securities as provided in this Declaration,
the Securities so issued shall be deemed to be validly issued, fully paid and
non-assessable, subject to Section 10.01 with respect to the Common Securities.

       (d)    Every Person, by virtue of having become a Holder or a Preferred
Security Beneficial Owner in accordance with the terms of this Declaration,
shall be deemed to have expressly assented and agreed to the terms of, and shall
be bound by, this Declaration.

                                       37
<PAGE>   43

       (e)    Every Person, by virtue of having become a Holder or a Preferred
Security Beneficial Owner in accordance with the terms of this Declaration,
shall be deemed to have covenanted to treat the Debentures as indebtedness and
the Securities as evidence of an indirect beneficial ownership interest in the
Debentures.

       Section 7.02 Execution and Authentication.

       (a)    The Securities shall be signed on behalf of the Trust by one
Administrative Trustee. In case any Administrative Trustee who shall have signed
any of the Securities shall cease to be such Administrative Trustee before the
Securities so signed shall be delivered by the Trust, such Securities
nevertheless may be delivered as though the person who signed such Securities
had not ceased to be such Administrative Trustee; and any Securities may be
signed on behalf of the Trust by such persons who, at the actual date of
execution of such Security, shall be the Administrative Trustees, although at
the date of the execution and delivery of the Declaration any such person was
not such an Administrative Trustee.

       (b)    One Administrative Trustee shall sign the Preferred Securities for
the Trust by manual or facsimile signature. Unless otherwise determined by the
Trust, such signature shall, in the case of Common Securities, be a manual
signature.

       A Preferred Security shall not be valid until authenticated by the manual
signature of an authorized officer of the Property Trustee. The signature shall
be conclusive evidence that the Preferred Security has been authenticated under
this Declaration.

       Upon a written order of the Trust signed by one Administrative Trustee,
the Property Trustee shall authenticate the Preferred Securities for original
issue by executing the Property Trustee's certificate of authentication
contained in the form of Preferred Securities attached hereto as Exhibit A-1.
The aggregate number of Preferred Securities outstanding at any time shall not
exceed the number set forth in the terms in Annex I hereto except as provided in
Sections 7.06 and 7.07.

       The Property Trustee may appoint an authenticating agent acceptable to
the Trust to authenticate Preferred Securities. An authenticating agent may
authenticate Preferred Securities whenever the Property Trustee may do so. Each
reference in this Declaration to authentication by the Property Trustee includes
authentication by such agent. An authenticating agent has the same rights as the
Property Trustee to deal with the Depositor or an Affiliate.

       The Property Trustee shall have the right to decline to authenticate and
deliver any Preferred Securities under this Section if the Trustee, being
advised by counsel, determines that such action may not lawfully be taken or if
the Trustee in good faith shall determine that such action would expose the
Trustee to personal liability to existing Holders.

       Section 7.03 Form and Dating. The Preferred Securities and the Property
Trustee's certificate of authentication shall be substantially in the form of

                                       38

<PAGE>   44

Exhibit A-l and the Common Securities shall be substantially in the form of
Exhibit A-2, each of which is hereby incorporated in and expressly made a part
of this Declaration. Certificates may be printed, lithographed or engraved or
may be produced in any other manner as is reasonably acceptable to the
Administrative Trustees, as evidenced by their execution thereof. The Securities
may have letters, numbers, notations or other marks of identification or
designation and such legends or endorsements required by law, stock exchange
rule, agreements to which the Trust is subject, if any, or usage (provided that
any such notation, legend or endorsement is in a form acceptable to the Trust).
The Trust at the direction of the Depositor shall furnish any such legend not
contained in Exhibit A-1 to the Property Trustee in writing. Each Preferred
Security shall be dated the date of its authentication. The terms and provisions
of the Securities set forth in Annex I and the forms of Securities set forth in
Exhibits A-1 and A-2 are part of the terms of this Declaration and to the extent
applicable, the Property Trustee and the Depositor, by their execution and
delivery of this Declaration, expressly agree to such terms and provisions and
to be bound thereby.

       The Preferred Securities are being offered and sold by the Trust pursuant
to a Purchase Agreement relating to the Preferred Securities, dated August 3,
2000, among the Trust, the Depositor and the Purchasers named therein (the
"Purchase Agreement").

       (a)    Global Securities. Preferred Securities offered and sold to
Qualified Institutional Buyers ("QIBs") in reliance on Rule 144A under the
Securities Act("Rule 144A") as provided in the Purchase Agreement, shall be
initially issued in the form of one or more permanent global Securities in
definitive, fully registered form without distribution coupons with the
appropriate global legends and Restricted Securities Legend set forth in Exhibit
A-1 hereto (each, a "Rule 144A Global Preferred Security"), which shall be
deposited on behalf of the purchasers of the Preferred Securities represented
thereby with the Property Trustee, at either its Delaware or New York office, as
custodian for the Depositary, and registered in the name of the Depositary or a
nominee of the Depositary, duly executed by the Trust and authenticated by the
Property Trustee as provided herein. The number of Preferred Securities
represented by the Rule 144A Global Preferred Security may from time to time be
increased or decreased by adjustments made on the records of the Property
Trustee and the Depositary or its nominee as hereinafter provided.

       (b)    Book-Entry Provisions. This Section 7.03(b) shall apply only to
the Rule 144A Global Preferred Securities and such other Preferred Securities in
global form as may be authorized by the Trust to be deposited with or on behalf
of the Depositary.

       An Administrative Trustee on behalf of the Trust shall execute and the
Property Trustee shall, in accordance with Section 7.02, authenticate and
deliver initially one or more Rule 144A Global Preferred Securities that (a)
shall be registered in the name of Cede & Co. or other nominee of the Depositary
and (b) shall be delivered by the Property Trustee to the Depositary or pursuant
to the Depositary's written instructions or held by the Property Trustee as
custodian for the Depositary.

                                       39

<PAGE>   45
       Unless and until definitive, fully registered certificated Preferred
Securities have been issued to the Preferred Security Beneficial Owners pursuant
to Section 7.03:

              (i)    the provisions of this Section 7.03 shall be in full force
       and effect;

              (ii)   the Trust, the Trustees, the Registrar and the Paying Agent
       shall be entitled to deal with the Depositary for all purposes of this
       Declaration (including the payment of Distributions on the Global
       Preferred Security and receiving approvals, votes or consents hereunder)
       as the Holder of the Preferred Securities and the sole holder of the
       Global Preferred Security and shall have no obligation to the Preferred
       Security Beneficial Owners;

              (iii)  to the extent that the provisions of this Section 7.03
       conflict with any other provisions of this Declaration, the provisions of
       this Section 7.03 shall control; and

              (iv)   the rights of the Preferred Security Beneficial Owners
       shall be exercised only through the Depositary and shall be limited to
       those established by law and agreements between such Preferred Security
       Beneficial Owners and the Depositary and/or the Participants and the
       Depositary shall receive and transmit payments of Distributions on the
       Global Preferred Securities to such Participants. The Depositary will
       make book-entry transfers among the Participants and receive and transmit
       payments of Distributions on the Global Preferred Securities to such
       Participants; provided that solely for the purposes of determining
       whether the Holders of the requisite amount of Preferred Securities have
       voted on any matter provided for in this Declaration, so long as
       Definitive Preferred Security Certificates have not been issued, the
       Trustees may conclusively rely on, and shall be protected in relying on,
       any written instrument (including a proxy) delivered to the Trustees by
       the Depositary setting forth the Preferred Security Beneficial Owners'
       votes or assigning the right to vote on any matter to any other Persons
       either in whole or in part.

       Members of, or participants in, the Depositary ("participants") shall
have no rights under this Declaration with respect to any Global Preferred
Security held on their behalf by the Depositary or by the Property Trustee as
the custodian of the Depositary or under such Global Preferred Security, and
the Depositary may be treated by the Trust, the Property Trustee and any agent
of the Trust or the Property Trustee as the absolute owner of such Global
Preferred Security for all purposes whatsoever. Notwithstanding the foregoing,
nothing herein shall prevent the Trust, the Property Trustee or any agent of the
Trust or the Property Trustee from giving effect to any written certification,
proxy or other authorization furnished by the Depositary or impair, as between
the Depositary and its Participants, the operation of customary practices of
such Depositary governing the exercise of the rights of a holder of a beneficial
interest in any Global Preferred Security.

                                       40

<PAGE>   46

       (c)    Certificated Securities. Except as provided in Section 7.03(d),
owners of beneficial interests in the Global Preferred Security will not be
entitled to receive physical delivery of certificated Preferred Securities.

       (d)    Subject to Section 9.05, a Global Preferred Security deposited
with the Depositary or with the Property Trustee as custodian for the Depositary
pursuant to this Section 7.03 shall be transferred to the beneficial owners
thereof in the form of certificated Preferred Securities only if such transfer
complies with Section 9.02 and (i) the Depositary notifies the Depositor that it
is unwilling or unable to continue as Depositary for such Global Preferred
Security or if at any time such Depositary ceases to be a "clearing agency"
registered under the Exchange Act, at a time when the Depositary is required to
be so registered to act as such depositary and the Administrative Trustees do
not appoint a successor qualified Depositary within 60 days after the
Depositor's receipt of such notice or the Depositor's becoming aware of such
cessation, (ii) the Administrative Trustees decide in their sole discretion that
such Global Preferred Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing.

       (e)    Any Global Preferred Security that is transferable to the
beneficial owners thereof in the form of certificated Preferred Securities
pursuant to this Section 7.03 shall be surrendered by the Depositary to the
Property Trustee located in the Borough of Manhattan, City of New York, to be so
transferred, in whole or from time to time in part, without charge, and the
Property Trustee shall authenticate and deliver, upon such transfer of each
portion of such Global Preferred Security, an equal aggregate liquidation
amount of Preferred Securities of authorized denominations in the form of
certificated Preferred Securities. Any portion of a Global Preferred Security
transferred pursuant to this Section shall be registered in such names and such
amounts as the Depositary shall direct. Any Preferred Security in the form of
certificated Preferred Securities delivered in exchange for an interest in the
Rule 144A Global Preferred Security shall, except as otherwise provided by
Section 9.02, bear the Restricted Securities Legend set forth in Section
9.02(h).

       (f)    Subject to the provisions of Section 7.03(e), the registered
holder of a Global Preferred Security may grant proxies and otherwise authorize
any Person, including Participants and Persons that may hold interests through
Participants, to take any action which a holder is entitled to take under this
Declaration or the Securities.

       (g)    In the event of the occurrence of any of the events specified in
Section 7.03(d), the Trust will promptly make available to the Property Trustee
a reasonable supply of certificated Securities in definitive, fully registered
form without DISTRIBUTION COUPONS.

       Section 7.04 Registrar, Paying Agent, Conversion Agent and Tender Agent.
The Administrative Trustees shall maintain in the Borough of Manhattan, City of
New York, State of New York (i) an office or agency where Preferred Securities
may be presented for registration of transfer or for exchange ("Registrar"),
(ii) an office or agency where Preferred Securities may be presented for payment
("Paying Agent") and (iii) an office or agency where Securities may be presented
for conversion ("Conversion Agent"). The Registrar shall keep a register of the
Preferred Securities and of their transfer and exchange. The Administrative
Trustees may appoint the Registrar, the Paying Agent and

                                       41

<PAGE>   47
the Conversion Agent and may appoint one or more co-Registrars, one or more
additional paying agents and one or more additional conversion agents in such
other locations as it shall determine. The term "Paying Agent" includes any
additional paying agent and the term "Conversion Agent" includes any additional
conversion agent. The Administrative Trustees may change any Paying Agent,
Registrar, co-Registrar or Conversion Agent without prior notice to any Holder;
provided that the Administrative Trustees shall provide notice of such change to
all Holders promptly thereafter. The Administrative Trustees shall notify the
Property Trustee of the name and address of any Agent not a party to this
Declaration. If the Administrative Trustees fail to appoint or maintain another
entity as Registrar, Paying Agent or Conversion Agent, the Property Trustee
shall act as such. The Trust or any of its Affiliates may act as Paying Agent,
Registrar, or Conversion Agent. The Trust shall act as Paying Agent, Registrar,
co-Registrar, and Conversion Agent for the Common Securities.

       The Trust initially appoints the Property Trustee as Registrar, Paying
Agent, and Conversion Agent for the Preferred Securities. The Property Trustee
shall also serve as Tender Agent and shall have the responsibilities of such
described in the Remarketing Agreement for so long as the Debentures are held by
the Property Trustee.

       Section 7.05 Paying Agent to Hold Money in Trust. The Trust shall require
each Paying Agent other than the Property Trustee to agree in writing that the
Paying Agent will hold in trust for the benefit of Holders or the Property
Trustee all money held by the Paying Agent for the payment of principal or
distribution on the Securities, and will notify the Property Trustee if there
are insufficient funds. While any such insufficiency continues, the Property
Trustee may require a Paying Agent to pay all money held by it to the Property
Trustee. The Administrative Trustees at any time may require a Paying Agent to
pay all money held by it to the Property Trustee and to account for any money
disbursed by it. Upon payment over to the Property Trustee, the Paying Agent (if
other than the Trust or an Affiliate of the Trust) shall have no further
liability for the money. If the Trust or the Depositor or an Affiliate of the
Trust or the Depositor acts as Paying Agent, it shall segregate and hold in a
separate trust fund for the benefit of the Holders all money held by it as
Paying Agent.

       Section 7.06 Replacement Securities. If the Holder of a Security claims
that the Security has been lost, destroyed or wrongfully taken or if such
Security is mutilated and is surrendered to the Trust or in the case of the
Preferred Securities to the Property Trustee, an Administrative Trustee on
behalf of the Trust shall issue and the Property Trustee, in the case of
Preferred Securities, shall authenticate a replacement Security if the Property
Trustee's and such Administrative Trustee's requirements, as the case may be,
are met. If required by the Property Trustee or such Administrative Trustee, an
indemnity bond must be provided by the Holder which must be sufficient in the
judgment of both to protect the Trustees, the Depositor or any authenticating
agent from any loss which any of them may suffer if a Security is replaced. The
Depositor may charge for its expenses in replacing a Security.

       In case any such mutilated, destroyed, lost or stolen Security has become
or is about to become due and payable, the Depositor in its discretion may,
instead of the Trust's issuing a new Security, pay or purchase such Security, as
the case may be.

                                       42
<PAGE>   48

       Section 7.07 Outstanding Preferred Securities. The Preferred Securities
outstanding at any time are all the Preferred Securities authenticated by the
Property Trustee except for those canceled by it, those delivered to it for
cancellation, and those described in this Section as not outstanding.

       If a Preferred Security is replaced or paid pursuant to Section 7.06
hereof, it ceases to be outstanding unless the Property Trustee receives proof
satisfactory to it that the replaced or paid Preferred Security is held by a
protected purchaser (as such term is used in Section 8-405 of the Delaware
Uniform Commercial Code).

       If Preferred Securities are considered paid in full in accordance with
the terms of this Declaration, they cease to be outstanding and Distributions on
them cease to accumulate.

       A Preferred Security does not cease to be outstanding because one of the
Trust, the Trustees, the Depositor or an Affiliate of the Depositor or the
Trustees holds such Security.

       Section 7.08 Preferred Securities in Treasury In determining whether the
Holders of the required amount of Securities have concurred in any direction,
waiver or consent, Preferred Securities owned by the Trust, the Trustees, the
Depositor or an Affiliate of the Depositor, as the case may be, shall be
disregarded and deemed not to be outstanding, except that for the purposes of
determining whether the Property Trustee shall be fully protected in relying on
any such direction, waiver or consent, only Securities which the Property
Trustee knows are so owned shall be so disregarded.

       Section 7.09 Temporary Securities. Until definitive Securities are ready
for delivery, the Trust may prepare and, in the case of the Preferred
Securities, the Property Trustee shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of definitive Securities
but may have variations that the Trust considers appropriate for temporary
Securities. Without unreasonable delay, the Trust shall prepare and deliver to
the Property Trustee Preferred Securities in certificated form (other than in
the case of Preferred Securities in global form) and thereupon any or all
temporary Preferred Securities (other than any such Preferred Securities in
global form) may be surrendered in exchange therefor, at the office of the
Registrar, and the Property Trustee shall authenticate and deliver an equal
aggregate liquidation amount of definitive Preferred Securities in certificated
form in exchange for temporary Preferred Securities (other than any such
Preferred Securities in global form).

       Section 7.10 Cancellation. Any Administrative Trustee on behalf of the
Trust at any time may deliver Preferred Securities to the Property Trustee for
cancellation. The Registrar, Paying Agent and Conversion Agent shall forward to
the Property Trustee any Preferred Securities surrendered to them for
registration of transfer, redemption, conversion, exchange or payment. The
Property Trustee shall promptly cancel all Preferred Securities, surrendered for
registration of transfer, redemption, conversion, exchange, payment, replacement
or cancellation and shall deliver to the Administrative Trustees a certificate
of cancellation. The Trust may not issue new Preferred Securities to replace
Preferred Securities that it has paid or that have been delivered to the
Property Trustee for cancellation or that any Holder has converted.

                              Transfer and Exchange

       Section 9.01 General.

       (a)    When Preferred Securities are presented to the Registrar or a
co-Registrar with a request to register a transfer or to exchange them for an
equal number of Preferred Securities represented by different certificates, the
Registrar shall register the transfer or make the exchange if its requirements
for such transactions are met. To permit registrations of transfers and
exchanges, the Administrative Trustees shall prepare and one Administrative
Trustee shall execute and the Property Trustee shall authenticate Preferred
Securities at the Registrar's request.

       (b)    Securities may only be transferred, in whole or in part, in
accordance with the terms and conditions set forth in this Declaration and in
the terms of the Securities. To the fullest extent permitted by law, any
transfer or purported transfer of any Security not made in accordance with this
Declaration shall be null and void.

       Subject to this Article IX, the Depositor and any Related Party may only
transfer Common Securities (i) in accordance with Article VIII of the Indenture,
or (ii) to the Depositor or a Related Party of the Depositor; provided that, any
such transfer is subject to the condition precedent that the transferor obtain
the written opinion of nationally recognized independent counsel experienced in
such matters that such transfer would not cause more than an insubstantial risk
that:

              (i) the Trust would not be classified for United States federal
income tax purposes as a grantor trust; and

              (ii) the Trust would be an Investment Company or the transferee
would become an Investment Company.

       (c)    The Administrative Trustees shall provide for the registration of
Securities and of transfers of Securities, which will be effected without charge
but only upon payment (with such indemnity as the Administrative Trustees may
require) in respect of any tax or other governmental charges that may be imposed
in relation to it. Upon surrender for registration of transfer of any
Securities, the Administrative Trustees shall cause one or more new Securities
to be issued in the name of the designated transferee or transferees and, in the
case of Preferred Securities, authenticated by the property trustee. Every
Security surrendered for registration of transfer shall be accompanied by a
written instrument of transfer in form satisfactory to the Administrative
Trustees and the Registrar or co-Registrar duly executed by the Holder or such
Holder's attorney duly authorized in writing. Each Security surrendered for
registration of transfer shall be cancelled in accordance with Section 7.10. A
transferee of a Security shall be entitled to the rights and subject to the
obligations of a Holder hereunder upon the receipt by such transferee of a
Security. By acceptance of a Security, each transferee shall be deemed to have
agreed to be bound by this Declaration.

                                       45
<PAGE>   51

       (d)    The Trust shall not be required (i) to issue, register the
transfer of, or exchange, Preferred Securities during a period beginning at the
opening of business 15 days before the day of any selection of Preferred
Securities for redemption set forth in the terms of the Securities as set forth
in Annex I hereto and ending at the close of business on the day of selection,
or (ii) to register the transfer or exchange of any Preferred Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Preferred Security being redeemed in part.

       (e)    All Preferred Securities issued upon any transfer or exchange
pursuant to the terms of this Declaration shall evidence the same security and
shall be entitled to the same benefits under this Declaration as the Preferred
Securities surrendered upon such transfer or exchange.

       Section 9.02 Transfer Procedures and Restrictions.

       (a)    General. Subject to Sections 9.02(b) and 9.02(h)(ii), if Preferred
Securities are issued upon the transfer, exchange or replacement of Preferred
Securities bearing the Restricted Securities Legend set forth in Exhibit A-1
hereto, or if a request is made to remove such Restricted Securities Legend on
Preferred Securities, the Preferred Securities so issued shall bear the
Restricted Securities Legend, or the Restricted Securities Legend shall not be
removed, as the case may be, unless there is delivered to the Trust and the
Property Trustee such satisfactory evidence, which may include an opinion of
counsel licensed to practice law in the State of New York, as may be reasonably
required by the Depositor, that (i) neither the legend nor the restrictions on
transfer set forth therein are required to ensure that transfers thereof comply
with the provisions of Rule 144A or (ii) that such Securities are not
"restricted" within the meaning of Rule 144 under the Securities Act. Upon
provision of such satisfactory evidence, the Property Trustee, at the written
direction of the Trust, shall authenticate and deliver Preferred. Securities
that do not bear the Restricted Securities Legend.

       (b)    Transfers After Effectiveness of Shelf Registration Statement.
After the effectiveness of a Shelf Registration Statement for any Preferred
Securities, all requirements pertaining to Restricted Securities Legends on any
Preferred Security included within such Shelf Registration Statement will cease
to apply, and beneficial interests in a Preferred Security in global form
without Restricted Securities Legends will be available to transferees of such
Preferred Securities upon directions to transfer such Holder's beneficial
interest in the Rule 144A Global Preferred Security. After the effectiveness of
the Shelf Registration Statement, an Administrative Trustee on behalf of the
trust shall execute and the property Trustee shall authenticate a Preferred
Security in global form without the restricted Securities Legend (the
"Unrestricted Global Preferred security") to deposit with the depositary to
evidence transfers of beneficial interests from the rule 144a global preferred
security.

       (c)    Transfer and Exchange of Definitive Preferred Securities. When
Definitive Preferred Securities are presented to the Registrar or co-Registrar

              (x)    to register the transfer of such Definitive
       Preferred Securities; or

                                       46
<PAGE>   52
                        (y)     to exchange such Definitive Preferred Securities
                for an equal number of Definitive Preferred Securities of
                another denomination;

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met,
provided, however, that the Definitive Preferred Securities surrendered for
transfer or exchange:

                        (i)     shall be duly endorsed or accompanied by a
        written instrument of transfer in form reasonably satisfactory to the
        Administrative Trustees and the Registrar or co-Registrar, duly executed
        by the Holder thereof or his attorney duly authorized in writing.

                        (ii)    in the case of Definitive Preferred Securities
        that are Restricted Preferred Securities, are being transferred or
        exchanged (x) pursuant to an effective registration statement under the
        Securities Act or (y) pursuant to, and in compliance with, clause (A) or
        (B) below:

                                (A)     if such Restricted Preferred Securities
                are being delivered to the Registrar by a Holder for
                registration in the name of such Holder, without transfer, such
                Holder shall deliver a certification to that effect (in the form
                set forth on the reverse of the Preferred Security); or

                                (B)     if such Restricted Preferred Securities
                are being transferred pursuant to an exemption from registration
                in accordance with Rule 144A under the Securities Act such
                Holder shall deliver: (i) a certification to that effect (in the
                form set forth on the reverse of the Preferred Security) and
                (ii) if the Trust or Registrar so requests, evidence reasonably
                satisfactory to them as to the compliance with the restrictions
                set forth in the Restricted Securities Legend.

                Definitive Preferred Securities that are transferred to QIBs in
accordance with Rule 144A under the Securities Act must be delivered to QIBs in
the form of a beneficial interest in the Rule 144A Global Preferred Security in
accordance with Section 9.02(d) except as otherwise provided in Section 7.03(d).

                (d)     Restrictions on Transfer of a Definitive Preferred
Security for a Beneficial Interest in a Global Preferred Security. A Definitive
Preferred Security may not be exchanged for a beneficial interest in a Global
Preferred Security except upon satisfaction of the requirements set forth below.
Upon receipt by the Property Trustee of a Definitive Preferred Security, duly
endorsed or accompanied by appropriate instruments of transfer, is form
satisfactory to the Property Trustee, together with written instructions
directing the Property Trustee to make, or to direct the Depositary to make, an
adjustment on its books and records with respect to such Global Preferred
Security to reflect an increase in the number of the Preferred Securities
represented by the Global Preferred Security, then the Property Trustee shall
cancel such Definitive Preferred Security and cause, or direct the Depositary to
cause, the aggregate number of Preferred Securities

                                       47
<PAGE>   53

represented by the Global Preferred Security to be increased accordingly. If no
Global Preferred Securities are then outstanding, an Administrative Trustee on
behalf of the Trust shall execute and the Property Trustee shall authenticate,
upon written order of any Administrative Trustee, an appropriate number of
Preferred Securities in global form.

                (e)     Transfer and Exchange of Global Preferred Securities.
The transfer and exchange of Global Preferred Securities or beneficial interests
therein shall be effected through the Depositary, in accordance with this
Declaration (including applicable restrictions on transfer set forth herein, if
any) and the procedures of the Depositary therefor.

                (f)     Transfer of a Beneficial Interest in a Global Preferred
Security for a Definitive Preferred Security. Definitive Preferred Securities
issued in exchange for a beneficial interest in a Global Preferred Security
pursuant to this Section 7.03(d) shall be registered in such names and in such
authorized denominations as the Depositary, pursuant to instructions from its
Participants or indirect participants or otherwise, shall instruct the Property
Trustee. The Property Trustee shall deliver such Preferred Securities to the
Persons in whose names such Preferred Securities are so registered in accordance
with the instructions of the Depositary.

                (g)     Restrictions on Transfer and Exchange of Global
Preferred Securities. Notwithstanding any other provisions of this Declaration
(other than the provisions set forth in Section 7.03), a Global Preferred
Security may not be transferred as a whole except by the Depositary to a nominee
of the Depositary or by any such nominee to another nominee of the Depositary or
by the Depositary or any such nominee to a successor Depositary or a nominee of
such successor Depositary.

                (h)     Legend.

                        (i)     Except as permitted by the following paragraph
        (ii), each Preferred Security certificate evidencing the Global
        Preferred Securities and the Definitive Preferred Securities (and all
        Preferred Securities issued in exchange therefor or substitution
        thereof) shall bear a legend the "Restricted Securities Legend") in
        substantially the following form:

                "EACH OF THE PREFERRED SECURITIES (OR ITS PREDECESSOR) WAS
        ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE
        UNITED STATES SECURITIES ACT OF 1933 (THE "SECURITIES ACT"), AND EACH OF
        THE PREFERRED SECURITIES AND ANY DEBENTURES ISSUED UPON EXCHANGE FOR THE
        PREFERRED SECURITIES REPRESENTED HEREBY AND ANY COMMON STOCK ISSUABLE
        UPON CONVERSION THEREOF MAY NOT BE OFFERED, SOLD OR OTHERWISE
        TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE
        EXEMPTION THEREFROM. EACH PURCHASER OF EACH OF THE PREFERRED SECURITIES
        IS HEREBY NOTIFIED THAT THE SELLER OF EACH OF THE PREFERRED SECURITIES
        MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE
        SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

                THE HOLDER OF THIS PREFERRED SECURITY AGREES FOR THE BENEFIT OF
        THE ISSUER AND THE COMPANY THAT (A) THIS PREFERRED SECURITY AND ANY
        DEBENTURES OR COMMON STOCK ISSUABLE UPON CONVERSION HEREOF MAY BE
        OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (i) TO A PERSON
        WHOM THE SELLER REASONABLY BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER"
        (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION
        MEETING THE REQUIREMENTS OF RULE 144A, (ii) PURSUANT TO AN EXEMPTION
        FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144
        THEREUNDER (IF AVAILABLE) OR (iii) PURSUANT TO AN EFFECTIVE REGISTRATION
        STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (i) THROUGH (iii)
        IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE
        UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION, AND (B) THE HOLDER
        WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF
        EACH OF THE PREFERRED SECURITIES FROM IT OF THE RESALE RESTRICTIONS
        REFERRED TO IN (A) ABOVE."

                        (ii)    Upon any sale or transfer of a Restricted
        Preferred Security (including any Restricted Preferred Security
        represented by a Global Preferred Security) pursuant to Rule 144 under
        the Securities Act or an effective registration statement under the
        Securities Act the Registrar shall, at the direction of the Trust,
        permit the Holder thereof to exchange such Restricted Preferred Security
        for an interest in the Unrestricted Global Preferred Security.

                 (i)     Cancellation or Adjustment of Global Preferred
        Security. At such time as all beneficial interests in a Global Preferred
        Security have either been exchanged for Definitive Preferred Securities
        to the extent permitted by the Declaration or redeemed, repurchased or
        cancelled in accordance with the terms of this Declaration, such Global
        Preferred Security shall be returned to the Depositary for cancellation
        or retained and cancelled by the Property Trustee. At any time prior to
        such cancellation, if any beneficial interest in a Global Preferred
        Security is exchanged for Definitive Preferred Securities, Preferred
        Securities represented by such Global Preferred Security shall be
        reduced and an adjustment shall be made on the books and records of the
        Property Trustee (if it is then the Registrar for such Global Preferred
        Security) with respect to such Global Preferred Security, by the
        Property Trustee or the Registrar, to reflect such reduction.

                (j)     No Obligation of the Property Trustee.

                        (i)     The Property Trustee shall have no
        responsibility or obligation to any preferred Security Beneficial Owner,
        a Participant in the Depositary or other Person with respect to the
        accuracy of the records of the Depositary or its nominee or of any
        Participant thereof, with respect to any ownership interest in the
        Preferred Securities or with respect to the delivery to any Participant,
        Preferred Security Beneficial Owner or other Person (other than the
        Depositary) of any notice (including any notice of redemption) or the
        payment of any amount, under or with respect to such

                                       49
<PAGE>   55

        Preferred Securities. All notices and communications to be given to the
        Holders and all payments to be made to Holders under the Preferred
        Securities shall be given or made only to or upon the order of the
        registered Holders (which shall be the Depositary or its nominee in the
        case of a Global Preferred Security). The rights of Preferred Security
        Beneficial Owners in any Global Preferred Security shall be exercised
        only through the Depositary subject to the applicable rules and
        procedures of the Depositary. The Property Trustee may conclusively rely
        and shall be fully protected in relying upon information furnished by
        the Depositary or agent thereof with respect to its Participants and any
        Preferred Security Beneficial Owners.

                        (ii)    The Property Trustee and 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
        Preferred Security (including any transfers between or among Depositary
        Participants or Preferred Security Beneficial Owners in any Global
        Preferred Security) 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.

                Section 9.03 Deemed Security Holders. The Trustees may treat the
Person in whose name any Certificate shall be registered on the books and
records of the Trust as the sole holder of such Certificate and of the
Securities represented by such Certificate for purposes of receiving
Distributions (subject to Section 2(b) of Annex 1) and for all other purposes
whatsoever and, accordingly, shall not be bound to recognize any equitable or
other claim to or interest in such Certificate or in the Securities represented
by such Certificate on the part of any Person, whether or not the Trust, the
Property Trustee, the Registrar or a co-Registrar shall have actual or other
notice thereof.

                Section 9.04 Notices to Depositary. Whenever a notice or other
communication to the Preferred Security Holders is required under this
Declaration, the Administrative Trustees shall, in the case of any Global
Preferred Security, give all such notions and communications specified herein to
be given to the Preferred Security Holders to the Depositary and shall have no
notice obligations to the Preferred Security Beneficial Owners.

                Section 9.05 Appointment of Successor Depositary. If the
Depositary elects to discontinue its services as securities depositary with
respect to the Preferred Securities, the Administrative Trustees may, in their
sole discretion, appoint a successor Depositary with respect to such Preferred
Securities.

this Declaration, the Securities Guarantee and the terms of the Securities, the
Depositor shall not be:

                        (i)     personally liable for the return of any portion
        of the capital contributions (or any return thereon) of the Holders of
        the Securities which shall be made solely from assets of the Trust; or

                        (ii)    required to pay to the Trust or to any Holder of
        Securities any deficit upon dissolution of the Trust or otherwise.

                (b)     The Holder of the Common Securities shall be liable for
all of the debts and obligations of the Trust (other than with respect to the
Securities) to the extent not satisfied out of the Trust's assets.

                (c)     Pursuant to Section 3803(a) of the Business Trust Act,
the Holders of the Preferred Securities 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.

                Section 10.02 Exculpation. (a) No Indemnified Person shall be
liable, responsible or accountable in damages or otherwise to the Trust or any
Covered Person for any loss, damage or claim incurred by reason of 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 the authority conferred on such Indemnified Person by this
Declaration or by law, except that an Indemnified Person shall be liable for any
such loss, damage or claim incurred by reason of such Indemnified Person's gross
negligence (or, in the case of the Property Trustee, negligence) or willful
misconduct with respect to such acts or omissions.

                (b)     An Indemnified Person shall be fully protected in

Indemnified Person, has been selected by it with reasonable care on behalf of
the Trust, including information, opinions, reports or statements as to the
value and amount of the assets, liabilities, profits, losses, or any other facts
pertinent to the existence and amount of assets from which Distributions to
Holders of Securities might properly be paid.

                Section 10.03 Fiduciary Duty. (a) To the extent that, at law or
in equity, an Indemnified Person has duties (including fiduciary duties) and
liabilities relating thereto to the Trust or to any other Covered Person, an
Indemnified Person acting under this Declaration shall not be liable to the
Trust or to any other Covered Person for its 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 an Indemnified Person

hereto to replace such other duties and liabilities of such Indemnified Person.

                (b)     Unless otherwise expressly provided herein:

                        (i)     whenever a conflict of interest exists or arises
        between an Indemnified Person and any Covered Person; or

                        (ii)    whenever this Declaration or any other agreement
        contemplated herein or therein provides that an Indemnified Person shall
        act in a manner that is, or provides terms that are, fair and reasonable
        to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such action
or provide such terms, considering in each case the relative interest of each
party (including its own interest) to such conflict, agreement, transaction or
situation and the benefits and burdens relating to such interests, any customary
or accepted industry practices, and any applicable generally accepted accounting
practices or principles. In the absence of bad faith by the Indemnified Person,
the resolution, action or term so made, taken or provided by the Indemnified
Person shall not constitute a breach of this Declaration or any other agreement
contemplated herein or of any duty or obligation of the Indemnified Person at
law or in equity or otherwise.

                (c)     Whenever in this Declaration an Indemnified Person is
permitted or required to make a decision

                        (i)     in its "discretion" or under a grant of similar
        authority, the Indemnified Person shall be entitled to consider such
        interests and factors as it desires, including its own interests, and
        shall have no duty or obligation to give any consideration to any
        interest of or factors affecting the Trust or any other Person; or

permitted by applicable law, the Debenture Issuer shall indemnify and hold
harmless each Indemnified Person from and against any loss, damage, liability,
tax, penalty, expense or claim of any kind or nature whatsoever incurred without
gross negligence (or, in the case of the Property Trustee, negligence), bad
faith or willful misconduct on its part, arising out of or in connection with
the acceptance or administration of the trust or trusts hereunder, including the
reasonable costs and expenses (including reasonable legal fees and expenses) of
defending itself against or investigating any claim or liability in connection
with the exercise or performance of any of its powers or duties hereunder. The
Debenture Issuer shall be entitled to participate in the defense of any action
arising hereunder and, to the extent it may wish, assume the defense thereof,
with counsel satisfactory to such

                                       52
<PAGE>   58

Indemnified Persons (who shall not, except with the consent of the Indemnified
Persons, be counsel to the Debenture Issuer). Upon assuming such defense, the
Debenture Issuer shall not be liable for any legal or other expenses
subsequently incurred by such Indemnified Persons in connection with the defense
thereof, other than reasonable costs of investigation. The Debenture Issuer
shall not, without the prior written consent of the Indemnified Persons, effect
any settlement of any pending or threatened action in respect of which any
Indemnified Person is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Person unless such settlement (i) includes
an unconditional release of such Indemnified Person from all liability on any
claims that are the subject matter of such action and (ii) does not include a
statement as to, or an admission of, fault, culpability or a failure to act by
or on behalf of an Indemnified Person.

                (b)     To the fullest extent permitted by applicable law,
expenses (including legal fees and expenses) incurred by an Indemnified Person
in defending any claim, demand, action, suit or proceeding shall, from time to
time, be advanced by the Debenture Issuer prior to the final disposition of such
claim, demand, action, suit or proceeding upon receipt by the Debenture Issuer
of 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 Section 10.4(a). The obligation to indemnify, as
set forth in this Section 10.04, shall survive the termination of this
Declaration and the resignation or removal of the Property Trustee or the
Delaware Trustee, as the case may be.

                Section 10.05 Outside Businesses. Any Covered Person, the
Depositor, the Delaware Trustee and the Property Trustee (subject to Section
5.03(c)) 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 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. None of the Depositor, any Covered Person, the Delaware Trustee,
the Administrative Trustees or the Property 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 any Covered Person, the Depositor, the Delaware Trustee and the
Property 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 Covered Person, thE Delaware Trustee and
the Property Trustee may engage or be interested in any financial or other
transaction with the Depositor or any Affiliate of the Depositor, or may act as
depositary for, trustee or agent for, or act on any committee or body of holders
of, securities or other obligations of the Depositor or its Affiliates.

                Section 11.01 Fiscal Year. The fiscal year ("Fiscal Year") of
the Trust shall be the calendar year, or such other year as is required by the
Code.

                Section 11.02 Certain Accounting Matters.

                (a)     At all times during the existence of the Trust, the
Administrative Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail, each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account
and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year by a firm of independent certified public accountants
selected by the Administrative Trustees.

                (b)     The Administrative Trustees shall cause to be prepared
and delivered to each of the Holders of Securities, within 90 days after the end
of each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss;

                (c)     The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders of Securities, any annual United
States federal income tax information statement, required by the Code,
containing such information with regard to the Securities held by each Holder as
is required by the Code and the Treasury Regulations. Notwithstanding any right
under the Code to deliver any such statement at a later date, the Administrative
Trustees shall endeavor to deliver all such statements within 30 days after the
end of each Fiscal Year of the Trust.

                (d)     The Administrative Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by

required to be filed by the Administrative Trustees on behalf of the Trust with
any state or local taxing authority.

                Section 11.03 Banking. The Administrative Trustees on behalf of
the Trust shall maintain one or more bank accounts in the name and for the sole
benefit of the Trust; provided, however, that all payments of funds in respect
of the Debentures held by the Property Trustee shall be made directly to the
Property Trustee Account and no other funds of the Trust shall be deposited in
the Property Trustee Account. The sole signatories for such accounts shall be
designated by the Administrative Trustees; provided, however, that the Property
Trustee shall designate the signatories for the Property Trustee Account.

                Section 11.04 Withholding. The Trust and the Administrative
Trustees on behalf of the Trust shall comply with all withholding requirements
under United States federal, state and local law. The Administrative Trustees on
behalf of the Trust shall request, and the Holders shall provide to the
Administrative Trustees, such forms or certificates as are necessary to
establish an exemption from withholding with respect to each Holder, and any
representations and forms as shall reasonably be requested by the Administrative
Trustees on behalf of the Trust to assist it in determining the extent of, and
in fulfilling the Trust's withholding obligations. The Administrative Trustees
shall file required forms with applicable jurisdictions and, unless an exemption
from withholding is properly established by a Holder, shall remit amounts
withheld with respect to the Holder to applicable jurisdictions. To the extent
that the Trust is required to withhold and pay over any amounts to any authority
with respect to Distributions or allocations to any Holder, the amount withheld
shall be deemed to be a distribution in the amount of the withholding to the
Holder. In the event of any claimed overwithholding, Holders shall be limited to
an action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Administrative
Trustees on behalf of the Trust may reduce subsequent Distributions by the
amount of such withholding.

                Section 12.01 Amendments. (a) Except as otherwise provided in
this Declaration or by any applicable terms of the Securities, this Declaration
may be amended from time to time by the Depositor, the Property Trustee and the
Administrative Trustees, without the consent of the Holders of the Securities,
(i) to cure any ambiguity, correct or supplement any provision in the
Declaration that may be inconsistent with any other provision, or to make any
other provisions with respect to ministerial matters or questions arising under
the Declaration, which shall not be inconsistent with the other provisions of
the Declaration, or (ii) to modify, eliminate or add to any provisions of the
Declaration to such extent as shall be necessary to ensure that the Trust will
not be taxable as a corporation or will be classified for United States federal
income tax purposes as a grantor trust at all times that any Securities are
outstanding or to ensure that the Trust will not be required to register as an
"investment company" under the Investment Company Act; provided, however, that
in the case of clause (i), such action shall not adversely affect in any
material respect the interests of any Holder of Securities, and any such
amendments of the Declaration shall become effective when notice thereof is
given to the Holders of the Securities.

                (b)     Except as provided in (c) below, and the terms of the
Securities, this Declaration may be amended by the Trustees and the Depositor
with (i) the consent of Holders representing not less than a Majority in
liquidation amount of the outstanding Preferred Securities, 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 as a grantor trust for United States federal
income tax purposes or the Trust's exemption from status as an "investment
company" under the investment Company Act.

                (c)     Without the consent of each Holder of Securities, the

Distribution on the Securities or otherwise adversely affect the amount of any
Distribution required to be made in respect of the Securities of a specified
date, (ii) restrict the right of a Holder of Securities to institute suit for
the enforcement of any such payment on or after such date or (iii) adversely
affect the conversion rights of the Securities.

                (d)     In executing, or accepting the additional trusts created
by, any amendment permitted by this Article or the modifications thereby of the
trusts created by this Declaration, the Property Trustee shall be entitled to
receive and shall be fully protected in relying upon, a written opinion of
counsel stating that the execution of such amendment is authorized or permitted
by this Declaration. The Property Trustee and the Delaware Trustee may, but
shall not be obligated to, enter into any such amendment which affects the
Property Trustee's or the Delaware Trustee's, as the case may be, own rights,
duties or immunities under this Declaration or otherwise. No amendment to which
the Delaware Trustee is not a party shall be effective without the consent of
the Delaware Trustee, if such amendment affects the Delaware Trustee's own
rights, duties or immunities under this Declaration or otherwise.

                Section 12.02 Meetings of the Holders of Securities: Action by
Written Consent. (a) Meetings of the Holders of any class of Securities may be
called at any time by the Administrative Trustees (or as provided in the terms
of the Securities) to consider and act on any matter on which Holders of such
class of Securities are entitled to act under the terms of this Declaration, the
terms of the Securities or the rules of any stock exchange on which the
Preferred Securities are listed or admitted for trading. Except as otherwise set
forth in the terms of the Securities, the Administrative Trustees shall call a
meeting of the Holders of such class if directed to do so by the Holders of at
least 25% in liquidation amount of such class of Securities. Such direction
shall be given by delivering to the Administrative Trustees one or more requests
in a writing stating that the signing Holders of Securities wish to call a
meeting and indicating the general or specific purpose for which the meeting is
to be called. Any Holders of Securities calling a meeting shall specify in
writing the Certificates held by the Holders of Securities exercising the right
to call a meeting and only those Securities represented by the Certificates so
specified shall be counted for purposes of determining whether the required
percentage set forth in the second sentence of this paragraph has been met.

                (b)     Except to the extent otherwise provided in the terms of
the Securities, the following provisions shall apply to meetings of Holders of
Securities:

                        (i)     notice of any such meeting shall be given to all
        the Holders of Securities having a right to vote thereat at least 7 days
        and not more than 60 days before the date of such meeting. Whenever a
        vote, consent or approval of the Holders of Securities is permitted or
        required under this Declaration or the rules of any stock exchange on
        which the Preferred Securities are listed or admitted for trading, such
        vote, consent or approval may be given at a meeting of the Holders of
        Securities. Any action that may be taken at a meeting of the Holders of
        Securities may be taken without a meeting and without prior notice if a
        consent in writing

                                       56
<PAGE>   62

        setting forth the action so taken is signed by the Holders of Securities
        owning not less than the minimum aggregate liquidation amount of
        Securities that would be necessary to authorize or take such action at a
        meeting at which all Holders of Securities having a right to vote
        thereon were present and voting. Prompt notice of the taking of action
        without a meeting shall be given to the Holders of Securities entitled
        to vote who have not consented in writing. The Administrative Trustees
        may specify that any written ballot submitted to the Holders for the
        purpose of taking any action without a meeting shall be returned to the
        Trust within the time specified by the Administrative Trustees;

                        (ii)    each Holder of a Security may authorize any
        Person to act for it by proxy on all matters in which a Holder of
        Securities is entitled to participate, including waiving notice of any
        meeting, or voting or participating at a meeting. No proxy shall be
        valid after the expiration of 11 months from the date thereof unless
        otherwise provided in the proxy. Every proxy shall be revocable at the
        pleasure of the Holder of Securities executing it. Except as otherwise
        provided herein, all matters relating to the giving, voting or validity
        of proxies shall be governed by the General Corporation Law of the State
        of Delaware relating to proxies, and judicial interpretations
        thereunder, as if the Trust were a Delaware corporation and the Holders
        of the Securities were stockholders of a Delaware corporation;

                        (iii)   each meeting of the Holders of the Securities
        shall be conducted by the Administrative Trustees or by such other
        Person that the Administrative Trustees may designate; and

                        (iv)    unless the Business Trust Act, this Declaration,
        the terms of the Securities, the Trust Indenture Act or the listing
        rules of any stock exchange on which the Preferred Securities are then
        listed or trading, provide otherwise, the Administrative Trustees, in
        their sole discretion, shall establish all other provisions relating to
        meetings of Holders of Securities, including notice of the time, place
        or purpose of any meeting at which any matter is to be voted on by any
        Holders of Securities, waiver of any such notice, action by consent
        without a meeting, the establishment of a record date, quorum
        requirements, voting in person or by proxy or any other matter with
        respect to the exercise of any such right to vote.

                                    TERMS OF
                       Remarketable Term Income Deferrable
                     Equity Securities (HIGH TIDES(SM)) and
                          HIGH TIDES Common Securities

                Pursuant to Section 7.01 of the Amended and Restated Declaration
of Trust, dated as of August 9, 2000 (as amended from time to time, the
"Declaration"), the designation, rights, privileges, restrictions, preferences
and other terms and provisions of the Preferred Securities and the Common
Securities are set out below (each capitalized term used but not defined herein
has the meaning set forth in the Declaration or the Indenture (as defined in the
Declaration) or, if not defined in the Declaration, Indenture or Remarketing
Agreement, as defined in the Offering Circular (as defined in the Declaration):

1.      Designation and Number.

        (a)     "Preferred Securities." 10,350,000 (including 1,350,000 relating
to the exercise of the full amount of the over-allotment option granted by the
Trust) Preferred Securities of the Trust with an aggregate liquidation
preference with respect to the assets of the Trust of FIVE HUNDRED SEVENTEEN
MILLION FIVE HUNDRED THOUSAND Dollars ($517,500,000) (including SIXTY-SEVEN
MILLION FIVE HUNDRED THOUSAND Dollars ($67,500,000) relating to the exercise of
the full amount of the over-allotment option granted by the Trust), and a
liquidation amount with respect to the assets of the Trust of $50 per Preferred
Security, are hereby designated for the purposes of identification only as
"Remarketable Term Income Deferrable Equity Securities (HIGH TIDES(SM))" (the
"Preferred Securities"). The Preferred Security Certificates evidencing the
Preferred Securities shall be substantially in the form attached hereto as
Exhibit A-1, with such changes and additions thereto or deletions therefrom as
may be required by ordinary usage, custom or practice or to conform to the rules
of any stock exchange or other organization on which the Preferred Securities
are listed, if any.

        (b)     "Common Securities." 350,000 (including 70,000 relating to the
exercise of the full amount of the over-allotment option granted by the Trust)
Common Securities of the Trust with an aggregate liquidation amount with respect
to the assets of the Trust of SEVENTEEN MILLION FIVE HUNDRED THOUSAND Dollars
($17,500,000) (including THREE MILLION FIVE HUNDRED THOUSAND Dollars
($3,500,000) relating to the exercise of the full amount of the option granted
by the Trust) and a liquidation amount with respect to the assets of the Trust
of $50 per Common Security, are hereby designated for the purposes of
identification only as "HIGH TIDES Common Securities" (the "Common Securities").
The Common Security Certificates evidencing the Common Securities shall be
substantially in the form attached hereto as Exhibit A-2, with such changes and
additions thereto or deletions therefrom as may be required by ordinary usage,
custom or practice.

<PAGE>   72

2.      Distributions.

        (a)     Distributions payable on each Security will accrue at the
Applicable Rate applied to the stated liquidation amount of $50 per Security,
such rate being the rate of interest payable on the Debentures to be held by the
Property Trustee. The Applicable Rate will be 5% per annum (the "Initial Rate")
from August 9, 2000 to but excluding the Reset Date. From the Reset Date, the
Applicable Rate will be the Term Rate established by the Remarketing Agent to be
effective on the Reset Date. The Applicable Rate will be increased by 0.50% per
annum during the continuation of a Registration Default until such Registration
Default is cured. Distributions in arrears for more than one quarter will bear
interest thereon compounded quarterly at the Applicable Rate (to the extent
permitted by applicable law) as described in the Declaration. The term
"Distributions" as used herein includes such quarterly Distributions, additional
Distributions on quarterly Distributions not paid on the applicable Distribution
Date and Additional Amounts, as applicable. A Distribution is payable only to
the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent the Property Trustee has funds available
therefor. The amount of Distributions payable for any period will be computed
for any full quarterly Distribution period on the basis of a 360-day year of
twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

        (b)     Distributions on the Securities will be cumulative, will accrue
from August 9, 2000 and will be payable quarterly in arrears, on the following
dates, which dates correspond to the interest payment dates on the Debentures:
February 1, May 1, August 1 and November 1 of each year, commencing on November
1, 2000, except as otherwise described below (each such date being a
"Distribution Date"). The Reset Date is any date (1) not later than August 1,
2005 (or, if such day is not a Business Day, the next succeeding Business Day),
and (2) not earlier than 70 Business Days prior to August 1, 2005, as may be
determined by the Remarketing Agent, in its sole discretion, for settlement of a
successful remarketing. The fifteenth day of the month immediately preceding
each Distribution Date is the record date for determining which holders of
Securities shall be paid the Distributions and Additional Amounts, if any,
payable on such Distribution Date. If the Reset Date is prior to the record date
for the immediately following Distribution Date, then Distributions and
Additional Amounts, if any, accrued from and after the Reset Date to but
excluding the immediately following Distribution Date shall be paid on such
Distribution Date to the person in whose name each Security is registered on the
relevant record date, subject to the Depositor's right to initiate a Deferral
Period. If the Reset Date is on or after the record date for the immediately
following Distribution Date, then (1) Distributions and Additional Amounts, if
any, accrued from and after the record date to but excluding the Reset Date
shall be paid on the immediately following Distribution Date to the person in
whose name each Security is registered on the relevant record date and (2)
Distributions and Additional Amounts, if any, accrued from and after the Reset
Date to but excluding the immediately following Distribution Date shall be paid
on the second Distribution Date immediately following the Reset Date to the
person in whose name each Security is registered on the relevant record date for
such second Distribution Date, subject in each case to the Depositor's right to
initiate a Deferral Period.

                                       A-2
<PAGE>   73

        So long as no Debenture Event of Default has occurred and is continuing,
the Depositor has the right under the Indenture to defer payments of interest by
extending the interest payment period from time to time on the Debentures for a
period not exceeding 20 consecutive quarters (each a "Deferral Period") and, as
a consequence of such deferral, Distributions will also be deferred. Despite
such deferral, quarterly Distributions will continue to accrue with interest
thereon (to the extent permitted by applicable law) at the Applicable Rate
compounded quarterly during any such Deferral Period. Prior to three Business
Days before a Regular Record Date relating to a Payment Resumption Date (as
defined in the Indenture), the Depositor may further extend such Deferral
Period; provided that such Deferral Period together with all such previous and
further extensions thereof may not exceed 20 consecutive quarters or extend
beyond (i) the maturity (whether at the stated maturity or by declaration of
acceleration, call for redemption or otherwise) of the Debentures under the
Indenture and (ii) in the case of a Deferral Period which begins prior to the
Reset Date, the Reset Date. Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the Regular
Record Date for the relevant Payment Resumption Date. Upon the termination of
any Deferral Period and the payment of all amounts then due, the Depositor may
commence a new Deferral Period, subject to the above requirements.

        (c)     Distributions on the Securities will be payable to the Holders
thereof as they appear on the books and records of the Trust at the close of
business on the relevant record dates. The relevant record dates shall be on the
fifteenth day of the month immediately preceding each relevant payment date,
except as otherwise described in this Annex I to the Declaration. Subject to any
applicable laws and regulations and the provisions of the Declaration, each such
payment in respect of Preferred Securities being held in book-entry form through
The Depository Trust Company (the "Depositary"), or any successor Depositary
appointed pursuant to the Declaration, will be made as described under the
heading "Description of HIGH TIDES -- Depository Procedures" in the Offering
Circular and each such payment in respect of Preferred Securities not being held
in book-entry form through the Depositary shall be made via checks mailed to
Holders at their addresses as they appear on the books and records of the Trust.
The relevant record dates for the Common Securities shall be the same record
dates as for the Preferred Securities. Distributions payable on any Securities
that are not punctually paid on any Distribution payment date, as a result of
the Depositor having failed to make a payment under the Debentures, will cease
to be payable to the Person in whose name such Securities are registered on the
relevant record date, and such defaulted Distribution will instead be payable to
the Person in whose name such Securities are registered on the special record
date or other specified date determined in accordance with the Indenture. If any
date on which Distributions are payable on the Securities is not a Business Day,
then payment of the Distribution payable on such date will be made on the next
succeeding day that is a Business Day (and without any additional Distributions
or other payment in respect of any such delay) except that, with respect to any
Redemption Date, if such Business Day is in the next succeeding calendar year,
such Redemption Date shall be the immediately preceding Business Day, in each
case with the same force and effect as if made on such date.

        (d)     In the event of an election by the Holder to convert its
Securities through the Conversion Agent into Common Stock pursuant to the terms
of the Securities as forth in this Annex I to the Declaration, no payment,
allowance or adjustment shall be made with respect to accumulated and unpaid
Distributions on such Securities, or be required to be made; provided that
Holders of Securities at the close of business on any record date for the
payment of Distributions will be entitled to receive the Distributions payable
on such Securities on the corresponding payment date notwithstanding the
conversion of such Securities into Common Stock following such record date.

        (e)     In the event that there is any money or other property held by
or for the Trust that is not accounted for hereunder, such property shall be
distributed Pro Rata (as defined herein) among the Holders of the Securities.

3.      Liquidation Distribution Upon Dissolution.

        In the event of any voluntary or involuntary dissolution of the Trust,
the Trust shall be liquidated by the Trustees as expeditiously as the Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to the Holders of the
Securities a Like Amount of Debentures, unless such distribution would not be
practical, in which event such Holders will be entitled to receive out of the
assets of the Trust available for distribution to Holders, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, an amount
equal to the aggregate liquidation amount thereof plus accrued and unpaid
Distributions thereon to the date of payment (such amount being the "Liquidation
Distribution"). If such Liquidation Distribution can be paid only in part
because the Trust has insufficient assets available to pay in full the aggregate
Liquidation Distribution, then the amounts payable directly by the Trust on the
Securities shall be paid on a Pro Rata basis in accordance with paragraph 9. The
Holder of the Common Securities will be entitled to receive Distributions upon
any such liquidation Pro Rata with the Holders of the Preferred Securities,
except as provided in paragraph 10.

4.      Redemption and Distribution.

        (a)     Upon the repayment or payment of the Debentures in whole or in
part, whether at maturity or upon redemption or otherwise (other than following
any distribution of the Debentures to the Holders), the proceeds from such
repayment or redemption shall be simultaneously applied to redeem, on a Pro Rata
basis, a Like Amount of Securities, on the redemption date, in an amount per
Security equal to the applicable Redemption Price, payable in cash, which
Redemption Price will be equal to (i) the liquidation amount of each of the
Securities plus any accrued and unpaid Distributions thereon (A) in the case of
the repayment of the Debentures at stated maturity, or (B) in the case of a
redemption of the Debentures in certain limited circumstances set forth in the
Indenture upon the occurrence of a Tax Event, or (ii) (A) in the case of an
Optional Redemption after August 5, 2003 until but excluding the Tender
Notification Date, the Initial Redemption Price; (B) in the case of an Optional
Redemption on or after the Reset Date (except in the event of a Failed Final
Remarketing), in accordance with the Term Call Protections or (C) in the event
of a

                                      A-4

<PAGE>   75

Failed Final Remarketing, 100% of the then outstanding aggregate principal
amount of the Securities being redeemed, plus accrued and unpaid interest
thereon.

        (b)     If fewer than all the outstanding Securities are to be so
redeemed, the Common Securities and the Preferred Securities will be redeemed
Pro Rata and the Preferred Securities to be redeemed will be as described in
Paragraph 4(f)(ii) below.

        (c)     The Depositor, as the Holder of the outstanding Common
Securities, shall have the right at any time (including, without limitation,
upon the occurrence of a Tax Event or Investment Company Event) to dissolve the
Trust and, after satisfaction of the creditors of the Trust, cause a Like Amount
of the Debentures to be distributed to the Holders of the Securities in
liquidation of the Trust, provided that neither the Depositor nor the
Administrative Trustees may cause the dissolution of the Trust during the period
beginning on the Business Day following the Tender Notification Date and ending
on the Reset Date (other than upon the occurrence of a Tax Event or an
Investment Company Event), provided that the Administrative Trustees shall have
received a No Recognition Opinion (as defined below) prior to the dissolution of
the Trust.

        (d)     If, at any time, a Tax Event shall occur and be continuing the
Depositor shall cause the Trustees to dissolve the Trust and, after satisfaction
of the creditors of the Trust, cause a Like Amount of Debentures to be
distributed to the Holders of the Securities in liquidation of the Trust within
90 days following the occurrence of such Tax Event; provided, however, that such
dissolution, liquidation and distribution shall be conditioned on (i) the
Trustees' receipt of an opinion of a nationally recognized independent tax
counsel (reasonably acceptable to the Trustees) 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 dissolution and distribution of
Debentures, and (ii) the Depositor being unable to avoid such Tax Event within
such 90-day period by taking some ministerial action or pursuing some other
reasonable measure that, in the sole judgment of the Depositor, will have no
adverse effect on the Trust, the Depositor or the Holders of the Preferred
Securities and will involve no material cost ("Ministerial Action").

        If (i) the Depositor has received an opinion (a "Redemption Tax
Opinion") of a nationally recognized independent tax counsel (reasonably
acceptable to the Trustees) experienced in such matters that, as a result of a
Tax Event, there is more than an insubstantial risk that (a) the Trust would not
be considered to be a grantor trust for United States federal income tax
purposes or (b) the Depositor would be precluded from deducting the interest on
the Debentures for United States federal income tax purposes, even after the
Debentures were distributed to the Holders of Securities upon liquidation of the
Trust as described in this paragraph 4(d), or (ii) the Trustees shall have been
informed by such tax counsel that it cannot deliver a No Recognition Opinion,
the Depositor shall have the right, upon not less than 30 nor more than 60 days'
notice, and within 90 days following the occurrence and continuation of such Tax
Event, to redeem the Debentures in whole, but not in part, for cash, for the
principal amount plus accrued and unpaid interest thereon and, following such

                                      A-5

<PAGE>   76

redemption, all the Securities will be redeemed by the Trust at the liquidation
amount of $50 per Security plus accrued and unpaid Distributions thereon;
provided, however, that, if at the time there is available to the Depositor or
the Trust the opportunity to eliminate, within such 90-day period, the Tax
Event by taking some Ministerial Action, the Trust or the Depositor will pursue
such Ministerial Action in lieu of redemption.

        In lieu of the foregoing options, the Depositor shall also have the
option of causing the Securities to remain outstanding and pay Additional
Amounts on the Debentures.

        "Tax Event" means that the Property Trustee shall have received an
opinion of a nationally recognized independent tax counsel to the Depositor
(reasonably acceptable to the Trustees) experienced in such matters (a
"Dissolution Tax Opinion") to the effect that, as a result of (i) any amendment
to, or change (including any announced prospective change (which shall not
include a proposed change), provided that a Tax Event shall not occur more than
90 days before the effective date of any such prospective change) in the laws
(or any regulations thereunder) of the United States or any political
subdivision or taxing authority therefor or therein, (ii) any judicial decision
or official administrative pronouncement, ruling, regulatory procedure, notice
or announcement, including any notice or announcement of intent to adopt such
procedures or regulations (an "Administrative Action") or (iii) any amendment to
or change in the administrative position or interpretation of any Administrative
Action or judicial decision that differs from the theretofore generally accepted
position, in each case, by any legislative body, court, governmental agency or
regulatory body, irrespective of the manner in which such amendment or change is
made known, which amendment or change is effective or such Administrative Action
or decision is announced, in each case, on or after the date of original
issuance of the Debentures or the issue date of the Preferred Securities issued
by the Trust, there is more than an insubstantial risk that (a) if the
Debentures are held by the Property Trustee, (x) the Trust is, or will be within
90 days of the date of such opinion, subject to United States federal income tax
with respect to interest accrued or received on the Debentures or subject to
more than a de minimal amount of other taxes, duties or other governmental
charges as determined by such counsel, or (y) any portion of interest payable by
the Depositor to the Trust (or OID accruing) on the Debentures is not, or within
90 days of the date of such opinion will not be, deductible by the Depositor in
whole or in part for United States federal income tax purposes or (b) with
respect to Debentures which are no longer held by the Property Trustee, any
portion of interest payable by the Depositor (or OID accruing) on the debentures
is not, or within 90 days of the date of such opinion will not be, deductible by
the Depositor in whole or in part for United States federal income tax purposes.

        If an Investment Company Event (as hereinafter defined) shall occur and
be continuing, the Depositor shall cause the Trustees to dissolve the Trust and,
after satisfaction of creditors of the Trust, cause a Like Amount of the
Debentures to be distributed to the Holders of the Securities in liquidation of
the Trust within 90 days following the occurrence of such Investment Company
Event.

                                      A-6

<PAGE>   77
       "Investment Company Event" means the occurrence of a change in law or
regulation or a written change in interpretation or application of law or
regulation by any legislative body, court, governmental agency or regulatory
authority (a "Change in 1940 Act Law"), to the effect that the Trust is or will
be considered an Investment Company which is required to be registered under the
Investment Company Act, which Change in 1940 Act Law becomes effective on or
after the date of the Offering Circular.

       After the date fixed for any distribution of Debentures: (i) the
Securities will no longer be deemed to be outstanding, (ii) the Depositary or
its nominee (or any successor Depositary or its nominee), as record Holder of
Preferred Securities represented by global certificates, will receive a
registered global certificate or certificates representing the Debentures to be
delivered upon such distribution and (iii) any certificates representing
Securities, except for certificates representing Preferred Securities held by
the Depositary or its nominee (or any successor Depositary or its nominee), will
be deemed to represent Debentures having an aggregate principal amount equal to
the aggregate stated liquidation amount of such Securities, with accrued and
unpaid interest equal to accrued and unpaid Distributions on such Securities
until such certificates are presented to the Depositor or its agent for transfer
or reissuance.

       (e) The Securities will not be redeemed unless all accrued and unpaid
Distributions have been paid on all Securities for all quarterly Distribution
periods terminating on or before the date of redemption.

       (f) Redemption, Distribution and Remarketing Procedures.

                     (i) Holders will be given not less than 20 nor more than 60
       days notice of an Optional Redemption. Holders will be given at least 30
       days but not more than 60 days notice of a redemption pursuant to
       paragraph 4(d). Notice of distribution of Debentures in exchange for the
       Securities will be given by the Administrative Trustees on behalf of the
       Trust by mail to each Holder of Securities to be exchanged not fewer than
       30 nor more than 60 days before the date fixed for exchange thereof. For
       purposes of the calculation of the date of redemption or exchange and the
       dates on which notices are given pursuant to this paragraph 4(f)(i)
       (other than notices in connection with a Remarketing, the terms of which
       shall be governed by the Remarketing Agreement), a redemption or
       distribution notice shall be deemed to be given on the day such notice is
       first mailed by first-class mail, postage prepaid, to Holders of
       Securities. Each redemption or distribution notice shall be addressed to
       the Holders of Securities at the address of each such Holder appearing in
       the books and records of the Trust. No defect in the redemption or
       distribution notice or in the mailing of either thereof with respect to
       any Holder shall affect the validity of the redemption or exchange
       proceedings with respect to any other Holder.

                                      A-7
<PAGE>   78

                     (ii) In the event that fewer than all the outstanding
       Securities are to be redeemed, the Securities to be redeemed shall be
       redeemed Pro Rata from each Holder of Securities, it being understood
       that, in respect of Preferred Securities registered in the name of and
       held of record by the Depositary (or any successor Depositary) or any
       nominee, the distribution of the proceeds of such redemption will be made
       to each Participant (or Person on whose behalf such nominee holds such
       securities) in accordance with the procedures applied by such agency or
       nominee.

                     (iii) If Securities are to be redeemed and the
       Administrative Trustees on behalf of the Trust gives a redemption or
       distribution notice, which notice may only be issued if the Debentures
       are redeemed as set out in this paragraph 4 (which notice will be
       irrevocable), then (A) with respect to Preferred Securities held in
       book-entry form, by 2:30 p.m., New York City time, on the redemption
       date, to the extent funds are available, with respect to Preferred
       Securities held in global form, the Property Trustee will deposit
       irrevocably with the Depositary (or successor Depositary) funds
       sufficient to pay the amount payable on redemption with respect to such
       Preferred Securities and will give the Depositary irrevocable
       instructions and authority to pay the amount payable on redemption to the
       Holders of such Preferred Securities, and (B) with respect to Preferred
       Securities issued in certificated form and Common Securities, to the
       extent funds are available, the Property Trustee will irrevocably deposit
       with the Paying Agent funds sufficient to pay the amount payable on
       redemption to the Holders of such Securities and will give the Paying
       Agent irrevocable instructions and authority to pay the amount payable on
       redemption to the Holders thereof upon surrender of their certificates.
       If a redemption or distribution notice shall have been given and funds
       deposited as required, then on the date of such deposit, all rights of
       Holders of such Securities so called for redemption will cease, except
       the right of the Holders of such Securities to receive the Redemption
       Price, but without interest on such Redemption Price, and such Securities
       will cease to be outstanding. Neither the Administrative Trustees nor the
       Trust shall be required to register or cause to be registered the
       transfer of any Securities that have been so called for redemption. If
       any date fixed for redemption of Securities is not a Business Day, then
       payment of the amount payable on such date will be made on the next
       succeeding day that is a Business Day (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 fixed for redemption. If payment of the
       Redemption Price in respect of any Securities is improperly withheld or
       refused and not paid either by the Trust or by the Depositor as guarantor
       pursuant to the relevant Securities Guarantee, Distributions on such
       Securities will continue to accrue at the then applicable rate, from the
       original redemption date to the date of payment, in which case the actual
       payment date

                                      A-8
<PAGE>   79

       will be considered the date fixed for redemption for purposes of
       calculating the amount payable upon redemption (other than for purposes
       of calculating any premium).

                     (iv) Redemption and/or distribution notices, as applicable,
       shall be sent by the Administrative Trustees on behalf of the Trust to
       (A) in the case of Preferred Securities held in book-entry form, the
       Depositary and, in the case of Preferred Securities held in certificated
       form, the Holders of such certificates and (B) in respect of the Common
       Securities, the Holder thereof.

                     (v) Subject to the foregoing and applicable law (including,
       without limitation, United States federal securities laws), the Depositor
       or any of its subsidiaries may at any time and from time to time purchase
       outstanding Preferred Securities, including by tender, in the open market
       or by private agreement; provided that neither the Depositor nor any of
       its Affiliates may purchase Preferred Securities on the Reset Date or
       submit orders in the Remarketing.

       5. Conversion Rights.

       The Holders of Securities shall have the right at any time prior to 5:00
p.m., New York City time, on the Tender Notification Date and, in the event of a
Convertible Remarketing or a Failed Final Remarketing, from and after the Reset
Date to and including August 1, 2030 (except that Securities called for
redemption by the Depositor will be convertible at any time prior to 5:00 p.m.,
New York City time on any Redemption Date), at their option, to cause the
Conversion Agent to convert Securities, on behalf of the converting Holders,
into shares of Common Stock (as defined in the Indenture) in the manner
described herein on and subject to the following terms and conditions:

       (a) The Securities will be convertible at the office of the Conversion
Agent into fully paid and nonassessable shares of Common Stock pursuant to the
Holder's direction to the Conversion Agent to exchange such Securities for a
portion of the Debentures theretofore held by the Trust on the basis of one
Security per $50 principal amount of Debentures, and immediately convert such
amount of Debentures into fully paid and nonassessable shares of Common Stock on
or prior to the Tender Notification Date into 0.5755 shares of Common Stock per
$50 principal amount of Debentures (which is equivalent to a conversion price of
$86.875 per share of Common Stock, subject to certain adjustments set forth in
the Indenture (as so adjusted, "Initial Conversion Price")). On and after the
Reset Date, the Securities may, at the option of the Trust and subject to the
results of the Remarketing, become nonconvertible or convertible into a
different number of shares of Common Stock.

       (b) In order to convert Securities into Common Stock the Holder shall
submit to the Conversion Agent an irrevocable request to convert Securities on
behalf of such Holder (the "Conversion Request"), together, if the Securities
are in certificated form, with such certificates. The Trust shall not cause the
conversion of any Debentures except pursuant to such a Conversion Request. The
Conversion Request

                                      A-9
<PAGE>   80

shall (i) set forth the number of Securities to be converted and the name or
names, if other than the Holder, in which the shares of Common Stock should be
issued and (ii) direct the Conversion Agent (a) to exchange such Securities for
a portion of the Debentures held by the Trust (at the rate of exchange specified
in the preceding paragraph) and (b) to immediately convert such Debentures on
behalf of such Holder, into Common Stock (at the conversion rate specified in
the preceding paragraph). The Conversion Agent shall notify the Property Trustee
of the Holder's election to exchange Securities for a portion of the Debentures
held by the Trust and the Property Trustee shall, upon receipt of such notice,
deliver to the Conversion Agent the appropriate principal amount of Debentures
for exchange in accordance with this Section 5. The Conversion Agent shall
thereupon notify the Depositor of the Holder's election to convert such
Debentures into shares of Common Stock. Holders of Securities at the close of
business on a Distribution record date will be entitled to receive the
Distribution payable on such Securities on the corresponding Distribution
payment date notwithstanding the conversion of such Securities following such
record date but prior to such distribution payment date. Except as provided
above, neither the Trust nor the Depositor will make, or be required to make,
any payment, allowance or adjustment upon any conversion on account of any
accumulated and unpaid Distributions accrued on the Securities, whether or not
in arrears, (including any Additional Amounts accrued thereon) surrendered for
conversion, or on account of any accumulated and unpaid dividends on the shares
of Common Stock issued upon such conversion, except to the extent that such
shares are held of record on the record date for any such dividends. Securities
shall be deemed to have been converted immediately prior to the close of
business on the day on which a Conversion Request relating to such Securities is
received by the Trust in accordance with the foregoing provision (the
"Conversion Date"). The Person or Persons entitled to receive the Common Stock
issuable upon conversion of the Debentures shall be treated for all purposes as
the record holder or holders of such Common Stock at such time. As promptly as
practicable on or after the Conversion Date, the Depositor shall issue and
deliver at the office of the Conversion Agent a certificate or certificates for
the number of full shares of Common Stock issuable upon such conversion,
together with the cash payment, if any, in lieu of any fraction of any share to
the Person or Persons entitled to receive the same, unless otherwise directed by
the Holder in the notice of conversion and the Conversion Agent shall distribute
such certificate or certificates to such Person or Persons.

       (c) Each Holder of a Security by his acceptance thereof appoints
Wilmington Trust Company "Conversion Agent" for the purpose of effecting the
conversion of Securities in accordance with this Section 5. In effecting the
conversion and transactions described in this Section 5, the Conversion Agent
shall be acting as agent of the Holders of Securities directing it to effect
such conversion transactions. The Conversion Agent is hereby authorized (i) to
exchange Securities from time to time for Debentures held by the Trust in
connection with the conversion of such Securities in accordance with this
Section 5 and (ii) to convert all or a portion of the Debentures into Common
Stock and thereupon to deliver such shares of Common Stock in accordance with
the provisions of this Section and to deliver to the Trust a new Debenture or
Debentures for any resulting unconverted principal amount.

                                      A-10
<PAGE>   81

       (d) No fractional shares of Common Stock will be issued as a result of
conversion, but in lieu thereof, such fractional interest will be paid in cash
by the Depositor to the Trust, which in turn will make such payment to the
Holder or Holders of Securities so converted.

       (e) The Depositor shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for issuance upon the
conversion of the Debentures, free from any preemptive or other similar rights,
such number of shares of Common Stock as shall from time to time be issuable
upon the conversion of all the Debentures then outstanding. Notwithstanding the
foregoing, the Depositor shall be entitled to deliver upon conversion of
Debentures, shares of Common Stock reacquired and held in the treasury of the
Depositor (in lieu of the issuance of authorized and unissued shares of Common
Stock), so long as any such treasury shares are free and clear of all liens,
charges, security interests or encumbrances. Any shares of Common Stock issued
upon conversion of the Debentures shall be duly authorized, validly issued and
fully paid and nonassessable. The Property Trustee shall deliver the shares of
Common Stock received upon conversion of the Debentures to the converting Holder
free and clear of all liens, charges, security interests and encumbrances,
except for United States withholding taxes. Each of the Depositor and the
Administrative Trustees on behalf of the Trust shall prepare and shall use its
best efforts to obtain and keep in force such governmental or regulatory permits
or other authorizations as may be required by law, and shall comply with all
applicable requirements as to registration or qualification of the Common Stock
(and all requirements to list the Common Stock issuable upon conversion of
Debentures that are at the time applicable), in order to enable the Depositor to
lawfully issue Common Stock to the Trust upon conversion of the Debentures and
the Trust to lawfully deliver the Common Stock to each Holder upon conversion of
the Securities.

       (f) The Depositor will pay any and all taxes that may be payable in
respect of the issue or delivery of shares of Common Stock on conversion of
Debentures and the delivery of the shares of Common Stock by the Trust upon
conversion of the Securities. The Depositor shall not, however, be required to
pay any tax which may be payable in respect of any transfer involved in the
issue and delivery of shares of Common Stock in a name other than that in which
the Securities so converted were registered, and no such issue or delivery shall
be made unless and until the Person requesting such issue has paid to the Trust
the amount of any such tax, or has established to the satisfaction of the Trust
that such tax has been paid.

       (g) Nothing in the preceding Paragraph (f) shall limit the requirement of
the Trust to withhold taxes pursuant to the terms of the Securities set forth in
this Annex I to the Declaration or in the Declaration itself or otherwise
require the Property Trustee or the Trust to pay any amounts on account of such
withholdings.

       (h) Notwithstanding anything to the contrary contained in this Annex I or
the Declaration, no Common Securities may be converted into Common Stock unless
all outstanding Securities are converted into Common Stock, which conversion
will result in the dissolution of the Trust.

6. Voting Rights - Preferred Securities.

       (a) Except as provided under paragraphs 6(b) and 8, as otherwise required
by law, the Declaration and the Indenture, the Holders of the Preferred
Securities will have no voting rights.

       (b) In addition to the rights of the Holders of the Preferred Securities
with respect to the enforcement of payment of principal and interest on the
Debentures set forth herein, in the Declaration or in the Indenture, if (i) a
Debenture Event of Default occurs and is continuing or (ii) the Depositor
defaults under the Preferred Securities Guarantee (each of (i) and (ii) being an
"Appointment Event"), then the Holders of the Preferred Securities, acting as a
single class, will be entitled by the vote of a Majority in liquidation amount
of the Preferred Securities to appoint a Special Trustee in accordance with
Section 5.06(a)(ii)(B) of the Declaration. Any Holder of Preferred Securities
(other than the Depositor, or any entity directly or indirectly controlling or
controlled by or under direct or indirect common control with the Depositor)
will be entitled to nominate any Person to be appointed as Special Trustee. Not
later than 30 days after such right to appoint a Special Trustee arises, the
Trustees (other than the Delaware Trustee) will convene a meeting for the
purpose of appointing a Special Trustee. If the Trustees fail to convene such
meeting within such 30-day period, the Holders of not less than 10% in aggregate
liquidation amount of the Preferred Securities will be entitled to convene such
meeting in accordance with Section 12.02 of the Declaration. The record date for
such meeting will be the close of business on the Business Day that is one
Business Day before the day on which notice of the meeting is sent to the
Holders. The provisions of the Declaration relating to the convening and conduct
of the meetings of the Holders will apply with respect to any such meeting.

       Any Special Trustee so appointed shall cease to be a Special Trustee if
the Appointment Event pursuant to which the Special Trustee was appointed and
all other Appointment Events cease to be continuing. A Special Trustee may be
removed without cause at any time by vote of the Holders of a Majority in
liquidation amount of the Preferred Securities at a meeting of the Holders of
the Preferred Securities in accordance with Section 5.06(ii)(B) of the
Declaration. The Holders of 10% in liquidation amount of the Preferred
Securities will be entitled to convene such a meeting in accordance with Section
12.02 of the Declaration. The record date for such meeting will be the close of
business on the Business Day which is one Business Day before the day on which
the notice of meeting is sent to Holders. Notwithstanding the appointment of a
Special Trustee, the Depositor shall retain all rights under the Indenture,
including the right to defer payments of interest by extending the interest
payment period on the Debentures.

       Subject to the requirements set forth in this paragraph and as long as
the Debentures are held by the Trust, the Holders of a majority in liquidation
amount of the outstanding Preferred Securities, voting separately as a class
may, and the Trustees shall not, without obtaining the prior approval of the
Holders of a Majority in aggregate liquidation amount of all Preferred
Securities (i) direct the time, method, and place of conducting any proceeding
for any remedy available to the Property Trustee hereunder or under the
Indenture, or executing any trust or power conferred upon the Property Trustee
hereunder or with respect to the Debentures; provided, however, that,

                                      A-12
<PAGE>   83

the Property Trustee shall have the right to decline to follow any such
direction if the Property Trustee being advised by counsel determines that the
action so directed may not lawfully be taken, or if the Property Trustee in good
faith shall, by a Responsible Officer or Officers of the Property Trustee,
determine that the proceedings so directed would be illegal or involve it in
personal liability, and provided further that nothing in this Declaration shall
impair the right of the Property Trustee to take any action deemed proper by the
Property Trustee and which is not inconsistent with such direction, (ii) waive
any past default and its consequences that is waivable under Section 5.13 of the
Indenture or otherwise, (iii) exercise any right to rescind or annul a
declaration that the principal of all the Debentures shall be due and payable or
(iv) consent to any amendment, modification or termination of the Indenture or
the Debentures, where such consent shall be required, provided however, that,
where a consent under the Indenture would require the consent or act of the
Holders of greater than a majority in principal amount of Debentures affected
thereby (a "Super Majority"), the Property Trustee may only give such consent or
take such action at the direction of the Holders of at least the proportion in
liquidation preference of the Preferred Securities which the relevant Super
Majority represents of the aggregate principal amount of the Debentures
outstanding. The Property Trustee shall not, and none of the other Trustees
shall in any event, revoke any action previously authorized or approved by a
vote of the Holders of the Preferred Securities, except by a subsequent vote of
the Holders of the Preferred Securities. Other than with respect to directing
the time, method and place of conducting any remedy available to the Property
Trustee or the Debenture Trustee as set forth above, the Property Trustee shall
not take any action in accordance with the directions of the Holders of the
Preferred Securities under this paragraph unless the Property Trustee has
obtained an opinion of tax counsel experienced in such matters 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.

       If an Event of Default under the Declaration has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay interest or principal on the Debentures on the date such interest or
principal is otherwise payable (or in the case of redemption on the redemption
date), then a Holder of Preferred Securities may directly institute a legal
proceeding, subject to the terms of the Indenture (including the subordination
provisions set forth in Article XII thereof), for enforcement of payment to such
Holder (a "Direct Action") of the principal of or interest on the Debentures
having a principal amount equal to the aggregate liquidation amount of the
Preferred Securities of such Holder on or after the respective due date
specified or provided for in the Debentures. Except as provided in the preceding
sentence, the Holders of Preferred Securities will not be able to exercise
directly any other remedy available to the Holders of the Debentures. In
connection with any Direct Action, the Holder of the Common Securities will be
subrogated to the rights of such Holder of Preferred Securities under the
Declaration to the extent of any payment made by the Debenture Issuer to such
Holder of Preferred Securities in such Direct Action. In addition, if the
Property Trustee fails to enforce its rights under the Debentures (other than
rights arising from an Event of Default described in the immediately preceding
sentence) after any Holder of Preferred Securities shall have made a written
request to the Property Trustee to enforce such rights, such Holder of Preferred
Securities may, to the fullest extent permitted by law, institute a direct
action

                                      A-13
<PAGE>   84

on behalf of the Trust to enforce the rights of the Debenture Trustee, the
Property Trustee or any other Person in accordance with the terms of the
Indenture or the Declaration, as the case may be.

       Any 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 Securities in the Trust or
pursuant to written consent without prior notice. The Administrative Trustees
will cause a notice of any meeting at which Holders of Preferred Securities are
entitled to vote to be mailed to each Holder of record of Preferred Securities.
Each such notice will include a statement setting forth the following
information (i) the date of such meeting, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
and (iii) instructions for the delivery of proxies.

       No vote or consent of the Holders of the Preferred Securities will be
required for the Trust to redeem and cancel Preferred Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

       Notwithstanding that Holders of Preferred Securities are entitled to vote
or consent under any of the circumstances described above, any of the Preferred
Securities that are owned by the Depositor, the Trustees or any Affiliate of the
Depositor or the Trustee shall not be entitled to vote or consent and shall, for
purposes of such vote or consent, be treated as if they were not outstanding,
except that for the purposes of determining whether the Property Trustee shall
be fully protected in relying on any such direction, waiver or consent, only
Securities which the Property Trustee knows are so owned shall be so
disregarded.

7. Voting Rights - Common Securities.

       (a) Except as provided under paragraphs 7(b), (c) and 8, in the Business
Trust Act and as otherwise required by law and the Declaration, the Holders of
the Common Securities will have no voting rights.

       (b) The Holders of the Common Securities are entitled, in accordance with
Article V of the Declaration, to vote to appoint, remove or replace any Trustee,
subject to the exclusive right of the Holders of the Preferred Securities to
appoint, remove or replace a Special Trustee, unless a Debenture Event of
Default shall have occurred and be continuing, in which event the Property
Trustee and the Delaware Trustee may only be removed by the Holders of a
Majority in liquidation amount of the Preferred Securities, voting as a class at
a meeting of the Holders of the Preferred Securities; and

        (c) Subject to Section 2.06 of the Declaration and only after the Event
of Default with respect to the Preferred Securities has been cured, waived, or
otherwise eliminated and subject to the requirements of the second to last
sentence of this paragraph, the Holders of a Majority in liquidation amount of
the Common Securities, voting separately as a class, may direct the time,
method, and place of conducting any proceeding for any remedy available to the
Property Trustee, or exercising any trust or power conferred upon the Property
Trustee under the Declaration, including (i) directing the time, method, place
of conducting any proceeding for any remedy

                                      A-14
<PAGE>   85
available to the Debenture Trustee, or exercising any trust or power conferred
on the Debenture Trustee with respect to the Debentures; provided, however, that
the Property Trustee shall have the right to decline to follow any such
direction if the Property Trustee being advised by counsel determines that the
action so directed may not lawfully be taken, or if the Property Trustee in good
faith shall, by a Responsible Officer or Officers of the Property Trustee,
determine that the proceedings so directed would be illegal or involve it in
personal liability, and provided further that nothing in this Declaration shall
impair the right of the Property Trustee to take any action deemed proper by the
Property Trustee and which is not inconsistent with such direction, (ii) waiving
any past default and its consequences that is waivable under Section 5.13 of the
Indenture, or (iii) exercising any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable, provided that,
where a consent or action under the Indenture would require the consent or act
of the Holders of greater than a majority in principal amount of Debentures
affected thereby (a "Super Majority"), the Property Trustee may only give such
consent or take such action at the direction of the Holders of at least the
proportion in liquidation amount of the Common Securities which the relevant
Super Majority represents of the aggregate principal amount of the Debentures
outstanding. Pursuant to this paragraph 7(c), the Property Trustee shall not
revoke any action previously authorized or approved by a vote of the Holders of
the Preferred Securities, except by a subsequent vote of the Holders of the
Preferred Securities. Other than with respect to directing the time, method and
place of conducting any remedy available to the Property Trustee or the
Debenture Trustee as set forth above, the Property Trustee shall not take any
action in accordance with the directions of the Holders of the Common Securities
under this paragraph unless the Property Trustee has obtained an opinion of tax
counsel 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. If the Property Trustee fails to enforce its rights under the
Debentures after any Holder of Common Securities shall have made a written
request to the Property Trustee to enforce such rights, such Holder of Common
Securities may, to the fullest extent permitted by law, institute a legal
proceeding directly against the Depositor, to enforce the Property Trustee's
rights, as holder of the Debentures, under the Indenture, without first
instituting any legal proceeding against the Property Trustee or any other
Person.

       Any approval or direction of Holders of Common Securities may be given at
a separate meeting of Holders of Common Securities convened for such purpose, at
a meeting of all of the Holders of Securities in the Trust or pursuant to
written consent without prior notice. The Administrative Trustees will cause a
notice of any meeting at which Holders of Common Securities are entitled to vote
to be mailed to each Holder of record of Common Securities. Each such notice
will include a statement setting forth (i) the date of such meeting, (ii) a
description of any resolution proposed for adoption at such meeting on which
such Holders are entitled to vote and (iii) instructions for the delivery of
proxies.

       No vote or consent of the Holders of the Common Securities will be
required for the Trust to redeem and cancel Common Securities or to distribute
the Debentures in accordance with the Declaration and the terms of the
Securities.

8. Amendments to Declaration and Indenture.

                                      A-15
<PAGE>   86

       (a) In addition to any requirements under Section 12.01 of the
Declaration, if any proposed amendment to the Declaration provides for, or the
Administrative Trustees otherwise propose to effect, (i) any action that would
adversely affect the powers, preferences or rights of the Securities, whether by
way of amendment to the Declaration or otherwise, or (ii) the dissolution,
winding-up or termination of the Trust, other than as described in Section 8.01
of the Declaration, then the Holders of outstanding Securities will be entitled
to vote on such amendment or proposal (but not on any other 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
Securities, voting together as a single class, provided, however, that, the
rights of Holders of Preferred Securities under Article V of the Declaration to
appoint, remove or replace a Special Trustee shall not be amended without the
consent of each Holder of Preferred Securities; and provided further that if any
amendment or proposal referred to in clause (i) above would adversely affect
only the Preferred Securities or only 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 Securities.

       (b) In the event the consent of the Property Trustee as the holder of the
Debentures is required under the Indenture with respect to any amendment,
modification or termination of the Indenture or the Debentures, the Property
Trustee shall request the direction of the Holders of the Securities with
respect to such amendment, modification or termination and shall vote with
respect to such amendment, modification or termination as directed by at least
the same proportion in aggregate stated liquidation preference of the
Securities; provided, however, that the Property Trustee shall not take any
action in accordance with the directions of the Holders of the Securities under
this paragraph 8(b) unless the Property Trustee has obtained an opinion of tax
counsel 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 on account of
such action.

9. Pro Rata.

       A reference in these terms of the Securities to any payment, Distribution
or treatment as being "Pro Rata" shall mean pro rata to each Holder of
Securities according to the aggregate liquidation amount of the Securities held
by the relevant Holder in relation to the aggregate liquidation amount of all
Securities outstanding unless, on any Distribution Date or redemption date an
Event of Default under the Declaration has occurred and is continuing, in which
case no payment of any Distribution on, or amount payable upon redemption 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 on all
outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the amount payable upon redemption
of the Preferred Securities, the full amount of such amount in respect of all
outstanding Preferred Securities shall have been made or provided for, and all
funds available to the Property Trustee shall first be applied to the payment in
full in cash of all Distribu-

                                      A-16
<PAGE>   87

tions on, or the amount payable upon redemption of Preferred Securities then due
and payable.

10. Ranking.

       The Preferred Securities rank pari passu and payment thereon shall be
made Pro Rata with the Common Securities except that, where a Debenture Event of
Default occurs and is continuing in respect of the Debentures held by the
Property Trustee, the rights of Holders of the Common Securities to payment in
respect of Distributions and payments upon liquidation, redemption and otherwise
are subordinated to the rights to payment of the Holders of the Preferred
Securities.

11. Acceptance of Securities Guarantee and Indenture.

       Each Holder of Preferred Securities and Common Securities, by the
acceptance thereof, agrees to the provisions of the Preferred Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein, and to the provisions of the Indenture
including the subordination provisions therein, which are each incorporated by
reference herein and which include, among other things, provisions relating to
certain rights of the Holders of the Preferred Securities all as set forth
therein.

12. No Preemptive Rights.

       The Holders of the Securities shall have no preemptive or similar rights
to subscribe for any additional securities.

13. Registration Rights.

       The Holders of the Preferred Securities shall have all the rights and
obligations set forth in the Registration Rights Agreement.

14. Miscellaneous.

       These terms constitute a part of the Declaration.

       The Depositor will provide a copy of the Declaration, the Preferred
Securities Guarantee or the Common Securities Guarantee, as may be appropriate,
and the Indenture to a Holder without charge on written request to the Depositor
at its principal place of business.

                          [FORM OF REVERSE OF SECURITY]

              Distributions payable on each Preferred Security will accrue at
the Applicable Rate applied to the stated liquidation amount of $50 per
Preferred Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. The Applicable Rate will be 5%
per annum (the "Initial Rate") from the date of original issuance of the
Securities to be excluding the Reset Date, and the Term Rate from the Reset Date
and thereafter. The Term Rate will be the rate established by the Remarketing
Agent to be effective on the Reset Date. The Applicable Rate will be increased
by 0.50% per annum during the continuation of a Registration Default.
Distributions in arrears for more than one quarter will bear interest thereon
compounded quarterly at the Applicable Rate (to the extent permitted by
applicable law). The term "Distributions" as used herein includes such quarterly
Distributions, additional Distributions on quarterly Distributions not paid on
the applicable Distribution Date and Additional Amounts, as applicable. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds available therefor. The amount of Distributions payable for
any period will be computed for any full quarterly Distribution period on the
basis of a 360-day year of twelve 30-day months, and for any period shorter than
a full quarterly Distribution period for which Distributions are computed,
Distributions will be computed on the basis of the actual number of days elapsed
per 30-day month.

              Except as otherwise described below, Distributions on the
Preferred Securities will be cumulative, will accrue from August 9, 2000 and
will be payable quarterly in arrears on February 1, May 1, August 1 and November
1, of each year (except as provided below), commencing on November 1, 2000 to
Holders of record at the close of business on the fifteenth day of the month
immediately preceding the applicable payment date, which payment dates shall
correspond to the interest payment dates (each an "Interest Payment Date") on
the Debentures. The Reset Date is any date (1) not later than August 1, 2005
(or, if such day is not a Business Day, the next succeeding Business Day), and
(2) not earlier than 70 Business Days prior to August 1, 2005, as may be
determined by the Remarketing Agent, in its sole discretion, for settlement of a
successful remarketing. The fifteenth day of the month immediately preceding
each Distribution Date is the record date for determining which holders of
Preferred Securities shall be paid the Distributions and Additional Amounts, if
any, payable on such Distribution Date. If the Reset Date is prior to the record
date for the immediately following Distribution Date, then Distributions and
Additional Amounts, if any, accrued from and after the Reset Date to but
excluding the immediately following Distribution Date shall be paid on such
Distribution Date to the person in whose name each Preferred Security is
registered on the relevant record date, subject to our right to initiate a
Deferral Period. If the Reset Date is on or after the record date for the
immediately following Distribution Date, then (1) Distributions and Additional
Amounts, if any, accrued from and after the record date to but excluding the
Reset Date shall be paid on the immediately following Distribution Date to the
person in whose name each Preferred Security is registered on the relevant
record date and (2) Distributions and Additional Amounts, if any, accrued from
and after the Reset Date to but excluding the immediately following Distribution
Date shall be paid on the second Distribution Date immediately following the
Reset Date to the person in whose name

                                       1
<PAGE>   95

each Preferred Security is registered on the relevant record date for such
second Distribution Date, subject in each case to the Depositor's right to
initiate a Deferral Period. So long as no Debenture Event of Default has
occurred and is continuing, the Debenture Issuer has the right under the
Indenture to defer payments of interest by extending the interest payment period
from time to time on the Debentures for a period not exceeding 20 consecutive
quarters (each a "Deferral Period") and, as a consequence of such deferral,
Distributions will also be deferred. Despite such deferral, quarterly
Distributions will continue to accrue with interest thereon (to the extent
permitted by applicable law) at the Applicable Rate compounded quarterly during
any such Deferral Period. Prior to the termination of any such Deferral Period,
the Debenture Issuer may further extend such Deferral Period; provided that such
Deferral Period together with all such previous and further deferrals thereof
may not exceed 20 consecutive quarters or extend beyond (i) the maturity
(whether at the stated maturity or by declaration of acceleration, call for
redemption or otherwise) of the Debentures under the Indenture or (ii) in the
case of a Deferral Period which begins prior to the Reset Date, the Reset Date.
Payments of accrued Distributions will be payable on an Interest Payment Date
elected by the Depositor to Holders as they appear on the books and records of
the Trust on the record date for such Interest Payment Date. Upon the
termination of any Deferral Period and the payment of all amounts then due, the
Debenture Issuer may commence a new Deferral Period, subject to the above
requirements.

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

              The Preferred Securities shall be convertible into shares of
Common Stock, through (i) the exchange of Preferred Securities for a portion of
the Debentures and (ii) the immediate conversion of such Debentures into Common
Stock, in the manner and according to the terms set forth in the Declaration.

              [Include if the Preferred Security contains a Restricted
Securities Legend -- Holders of Restricted Preferred Securities shall have all
the rights and obligations set forth in the Registration Rights Agreement.]

                          [FORM OF REVERSE OF SECURITY]

              Distributions payable on each Common Security will accrue at the
Applicable Rate applied to the stated liquidation amount of $50 per Common
Security, such rate being the rate of interest payable on the Debentures to be
held by the Property Trustee. The Applicable Rate will be 5% per annum (the
"Initial Rate") from the date of original issuance of the Securities to be
excluding the Reset Date, and the Term Rate from the Reset Date and thereafter.
The Term Rate will be the rate established by the Remarketing Agent to be
effective on the Reset Date. Distributions in arrears for more than one quarter
will bear interest thereon compounded quarterly at the Applicable Rate (to the
extent permitted by applicable law). The term "Distributions" as used herein
includes quarterly Distributions, additional Distributions on quarterly
Distributions not paid on the applicable Distribution Date and Additional
Amounts, as applicable. A Distribution is payable only to the extent that
payments are made in respect of the Debentures held by the Property Trustee and
to the extent the Property Trustee has funds available therefor. The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 30-day month.

              Except as otherwise described below, Distributions on the Common
Securities will be cumulative, will accrue from August 9, 2000 and will be
payable quarterly in arrears on February 1, May 1, August 1 and November 1 of
each year (except as provided below), commencing on November 1, 2000 to Holders
of record at the close of business on the fifteenth day of the month immediately
preceding the applicable payment date, which payment dates shall correspond to
the interest payment dates (each, an "Interest Payment Date") on the Debentures.
The Reset Date is any date (1) not later than August 1, 2005, or if the day is
not a Business Day, the next succeeding Business Day, and (2) not earlier than
70 Business Days prior to August 1, 2005, as may be determined by the
Remarketing Agent, in its sole discretion, for settlement of a successful
remarketing. The fifteenth day of the month immediately preceding each
Distribution Date is the record date for determining which holders of Common
Securities shall be paid the Distributions and Additional Amounts, if any,
payable on such Distribution Date. If the Reset Date is prior to the record date
for the immediately following Distribution Date, then Distributions and
Additional Amounts, if any, accrued from and after the Reset Date to but
excluding the immediately following Distribution Date shall be paid on such
Distribution Date to the person in whose name each Common Security is registered
on the relevant record date, subject to our right to initiate a Deferral Period.
If the Reset Date is on or after the record date for the immediately following
Distribution Date, then (1) Distributions and Additional Amounts, if any,
accrued from and after the record date to but excluding the Reset Date shall be
paid on the immediately following Distribution Date to the person in whose name
each Common Security is registered on the relevant record date and (2)
Distributions and Additional Amounts, if any, accrued from and after the Reset
Date to but excluding the immediately following Distribution Date shall be paid
on the second Distribution Date immediately following the Reset Date to the
person in whose name each Common Security is registered on the relevant record
date for such second Distribution Date, subject in each case to the Depositor's
right to initiate a Deferral

Period. So long as no Debenture Event of Default has occurred and is continuing,
the Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period from time to time on the
Debentures for a period not exceeding 20 consecutive quarters (each a "Deferral
Period") and, as a consequence of such deferral, Distributions will also be
deferred. Despite such deferral, quarterly Distributions will continue to accrue
with interest thereon (to the extent permitted by applicable law) at the
Applicable Rate compounded quarterly during any such Deferral Period. Prior to
the termination of any such Deferral Period, the Debenture Issuer may further
extend such Deferral Period; provided that such Deferral Period together with
all such previous and further deferrals thereof may not exceed 20 consecutive
quarters or extend beyond (i) the maturity (whether at the stated maturity or by
declaration of acceleration, call for redemption or otherwise) of the Debentures
under the Indenture or (ii) in the case of a Deferral Period which begins prior
to the Reset Date, the Reset Date. Payments of accrued Distributions will be
payable on an Interest Payment Date elected by the Depositor to Holders as they
appear on the books and records of the Trust on the record date for such
Interest Payment Date. Upon the termination of any Deferral Period and the
payment of all amounts then due, the Debenture Issuer may commence a new
Deferral Period, subject to the above requirements.

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

              The Common Securities shall be convertible into shares of Common
Stock, through (i) the exchange of Common Securities for a portion of the
Debentures and (ii) the immediate conversion of such Debentures into Common
Stock, in the manner and according to the terms set forth in the Declaration;
provided that no Common Securities may be converted into Common Stock unless
all outstanding Securities are converted into Common Stock, which conversion
will result in the dissolution of the Trust.
