HOLDINGS, INC., a Delaware corporation (including any successors or assigns, the
"Depositor"), First Union National Bank, a national banking association
organized under the laws of the United States (the "Property Trustee"), and

         1. The trust created hereby shall be known as "HCC Capital Trust II,"
in which name the Issuer Trustees, or the Depositor to the extent provided
herein, may conduct the business of the Trust, make and execute contracts, and
sue and be sued.

         2. The Depositor hereby assigns, transfers, conveys and sets over to
the Property Trustee the sum of $10. The Property Trustee hereby acknowledges
receipt of such amount in trust from the Depositor, which amount shall
constitute the initial trust estate. The Property Trustee hereby declares that
it will hold the trust estate in trust for the Depositor. It is the intention of
the parties hereto that the Trust created hereby constitute a business trust

issuing and selling preferred securities ("Preferred Securities") representing
undivided beneficial interests in the assets of the Trust in exchange for cash
and investing the proceeds thereof in Junior Subordinated Debentures of the
Depositor (the "Debentures"), (ii) issuing and selling common securities
("Common Securities" and, together with the Preferred Securities, "Trust
Securities") representing undivided beneficial interests in the assets of the
Trust to the Depositor in exchange for cash and investing the proceeds thereof
in additional Debentures and (iii) engaging in such other activities as are
necessary, convenient or incidental thereto.

         3. Concurrent with the first issuance of any Trust Securities by the
Trust, the Depositor and the Issuer Trustees intend to enter into an amended and
restated Trust Agreement, satisfactory to each such party, to provide for the
contemplated operation of the Trust created hereby and the issuance of the
Preferred Securities and the Common Securities referred to therein. Prior to the
execution and delivery of such amended and restated Trust Agreement, the Issuer
Trustees shall not have any duty or obligation hereunder or with respect to the
trust estate.

         4. The Depositor and the Property Trustee hereby authorize and direct
the Depositor, as the Depositor of the Trust, (i) to file with the Securities
and Exchange Commission (the "Commission") and execute, in each case on behalf
of the Trust, (a) the

Trust such applications, reports, surety bonds, irrevocable consents,

behalf of the Trust, may deem necessary or desirable; and (iv) to execute on
behalf of the Trust that certain Underwriting Agreement relating to the

"investment company" required to be registered under the 1940 Act, or taxed as a
corporation for United States Federal income tax purposes and so that the
Debentures will be treated as indebtedness of the Depositor for United States
Federal income tax purposes. In this connection, each Administrator, the
Property Trustee or the Holders of at least a majority in Liquidation Amount of
the Common Securities are authorized to take any action, not inconsistent with
applicable law, the Certificate of Trust or this Trust Agreement, that such
Administrator, the Property Trustee or such Holders of Common Securities
determine in their discretion to be necessary or desirable for such purposes, as
long as such action does not adversely affect in any material respect the
interests of the Holders of the Outstanding Preferred Securities. In no event
shall the Administrators take any action pursuant to the preceding sentence or
any other provision herein that would constitute discretionary control over the
assets of the Trust for purposes of Section 3(21) of ERISA. In no event shall
the Administrators or the Issuer Trustees be liable to the Trust or the Holders
for any failure to comply with this section that results from a change in law or
regulation or in the interpretation thereof.

property deposited or held from time to time in the Payment Account shall be

any priority of payments provided for herein.

     (b) The Property Trustee shall deposit in the Payment Account, promptly

                                   ARTICLE IV

                      CERTAIN TERMS OF THE TRUST SECURITIES

     Section 4.1. Distributions.

     The term "Distributions" as used in this Trust Agreement includes such cash
distributions and any such accumulated amounts, including Additional Interest
and Additional Amounts, that are payable unless otherwise stated.

     (a) The Trust Securities represent undivided beneficial ownership interests
in the Trust Property, and, as a practical matter, the Distributions on the
Preferred Securities shall be payable at the rates and on the dates that
payments of interest are made on the Debentures. Accordingly:

          (i) Distributions on the Trust Securities shall be cumulative, and
     will accumulate whether or not there are funds of the Trust available for
     the payment of Distributions. Distributions shall accrue from _________,
     2000 and shall be payable quarterly in arrears on March 30, June 30,
     September 30 and December 30 of each year, commencing on ____________,
     2000, except as provided below. If any date on which a Distribution is
     otherwise payable on the Trust Securities is not a Business Day, then the
     payment of such Distribution shall be made on the next succeeding day that
     is a Business Day (and without any interest or other payment in respect of
     any such delay) except that, if such Business Day is in the next succeeding
     calendar year, payment of such Distribution shall be made on the
     immediately preceding Business Day, in each case with the same force and
     effect as if made on such date (each date on which distributions are
     payable in accordance with this Section 4.1(a), a "Distribution Date").

                                       16
<PAGE>   22

          (ii) 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 extending, in the aggregate, beyond the
     maturity date of the Debentures (each, an "Interest Payment Deferral
     Period"). During such Interest Payment Deferral Period, no interest shall
     be due and payable on the Debentures. As a consequence of such deferral,
     Distributions on the Preferred Securities will also be deferred. Despite
     such deferral, quarterly Distributions will accrue Additional Interest (to
     the extent permitted by applicable law).

          (iii) Distributions in arrears for more than one quarter will
     accumulate and compound at a rate of ____% per annum of the Liquidation
     Amount of the Trust Securities. The amount of Distributions payable for any
     period less than a full period shall be computed on the basis of a 360-day
     year of twelve 30-day months. Distributions payable for each full
     Distribution period will be computed by dividing the rate per annum by
     four.

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

     (b) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which with
respect to Book-Entry Preferred Securities shall be one Business Day prior to
the relevant Redemption Date, and, with respect to Preferred Securities not in
book-entry-only form, the date 15 days prior to the relevant Redemption Date or,
in the case of an Interest Payment Deferral Period as described in subclause
(a)(ii) above, on the first record date after the end of the Interest Payment
Deferral Period.

     Section 4.2. Redemption.

     (a) On each Debenture Redemption Date and on the stated maturity of the
Debentures, the Trust will be required to redeem a Like Amount of Trust
Securities at the Redemption Price.

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

          (i)   the Redemption Date;

          (ii)  the Redemption Price;

          (iii) the CUSIP number(s) of the Preferred Securities affected;

                                       17
<PAGE>   23

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

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

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

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

     (d) If the Property Trustee gives a notice of redemption in respect of any
Trust Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), the Property Trustee will, with respect to
Book-Entry Preferred Securities, irrevocably deposit with the Clearing Agency
for such Book-Entry Preferred Securities, to the extent available, funds
sufficient to pay the applicable Redemption Price and will give such Clearing
Agency irrevocable instructions and authority to pay the Redemption Price to the
Holders thereof. If the Preferred Securities are not in book-entry-only form,
the Property Trustee, subject to Section 4.2(c), will irrevocably deposit with
the Paying Agent, to the extent available, funds sufficient to pay the
applicable Redemption Price and will give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the Holders thereof
upon surrender of their Preferred Securities Certificates. Notwithstanding the
foregoing, Distributions payable on or prior to the Redemption Date for any
Trust Securities called for redemption shall be payable to the Holders of such
Trust Securities as they appear on the Register for the Trust Securities on the
relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited as required, then
immediately prior to the close of business on the date of such deposit, all
rights of Holders holding Trust Securities so called for redemption will cease,
except the right of such Holders to receive the Redemption Price and any
Distribution payable on or prior to the Redemption Date, but without interest,
and such Securities will cease to be outstanding. In the event that any date on
which any Redemption Price is payable is not a Business Day, then payment of the
Redemption Price payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay), except that, if such Business Day falls in the next calendar
year, such payment will be made on the immediately preceding Business Day, in
each case, with the same force and effect as if made on such date. In the event
that payment of the Redemption Price in respect of any Trust Securities called
for redemption is improperly withheld or refused and not paid either by the
Trust or by the Depositor pursuant to the Guarantee, Distributions on such Trust
Securities will continue to accrue, at the then applicable rate, from the
Redemption Date originally established by the Trust for such Trust Securities to
the date such Redemption Price is actually paid, in which case the actual
payment date will be the date fixed for redemption for purposes of calculating
the Redemption Price.

                                       18
<PAGE>   24

     (e) Payment of the Redemption Price on the Trust Securities shall be made
to the recordholders thereof as they appear on the Securities Register for the
Trust Securities on the relevant record date, which with respect to Book-Entry
Preferred Securities shall be one Business Day prior to the relevant Redemption
Date, and, with respect to Preferred Securities not in book-entry-only form, the
date 15 days prior to the relevant Redemption Date.

     (f) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities. The particular Preferred Securities to be redeemed
shall be selected on a pro rata basis (based upon Liquidation Amounts) not more
than 60 days prior to the Redemption Date by the Property Trustee from the
Outstanding Preferred Securities not previously called for redemption. The
Property Trustee shall promptly notify the Security Registrar in writing of the
Preferred Securities selected for redemption and, in the case of any Preferred
Securities selected for partial redemption, the Liquidation Amount thereof to be
redeemed. For all purposes of this Trust Agreement, unless the context otherwise
requires, all provisions relating to the redemption of Preferred Securities
shall relate, in the case of any Preferred Securities redeemed or to be redeemed
only in part, to the portion of the Liquidation Amount of Preferred Securities
that has been or is to be redeemed.

     (g) Subject to obtaining any required regulatory approval, if, at any time,
a Tax Event or an Investment Company Event shall occur and be continuing, the
Depositor shall have the right, upon not less than 30 nor more than 60 days'
notice, to redeem the Debentures, in whole or in part, for cash within 90 days
following the occurrence of such Special Event, and, following such redemption,
a Like Amount of Preferred Securities shall be redeemed by the Trust at the
Redemption Price on a pro rata basis; 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 Special Event by taking some ministerial action,
such as filing a form or making an election or pursuing some other similar
reasonable measure that will have no adverse effect on the Trust, the Depositor
or the Holders of the Securities, then the Depositor or the Administrators on
behalf of the Trust will pursue such measure in lieu of redemption.

     Section 4.3. Subordination of Common Securities.

     (a) Payment of Distributions on, the Redemption Price of, and the
Liquidation Distribution in respect of, the Trust Securities, as applicable,
shall be made, subject to Section 4.2(f), pro rata among the Common Securities
and the Preferred Securities based on the Liquidation Amount of the Trust
Securities; provided, however, that if on any Distribution Date or Redemption
Date any Event of Default resulting from a Debenture Event of Default shall have
occurred and be continuing, no payment of any Distribution on, or Redemption
Price of, any Common Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Securities, shall be made
unless payment in full in cash of all accumulated and unpaid Distributions on
all Outstanding Preferred Securities for all Distribution periods terminating on
or prior thereto, or in the case of payment of the Redemption Price the full
amount of such Redemption Price on all Outstanding Preferred Securities, shall
have been made or provided for, and all funds immediately available to the
Property Trustee shall first be

                                       19

applied to the payment in full in cash of all Distributions on, or the
Redemption Price of, Preferred Securities then due and payable.

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

     Section 4.4. Payment Procedures.

     Payments in respect of the Preferred Securities shall be made by check
mailed to the address of the Person entitled thereto as such address shall
appear on the Securities Register or, if the Preferred Securities are held by a
Clearing Agency, such Distributions shall be made to the Clearing Agency in
immediately available funds, which shall credit the relevant Persons' accounts
at such Clearing Agency on the applicable distribution dates. Payments in
respect of the Common Securities shall be made in such manner as shall be
mutually agreed between the Property Trustee and the Holder of the Common
Securities.

     Section 4.5. Tax Returns and Reports.

     The Administrators shall prepare (or cause to be prepared), at the
Depositor's expense, and file all United States Federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrators shall (a) prepare and file (or cause
to be prepared and filed) the appropriate Internal Revenue Service form required
to be filed in respect of the Trust in each taxable year of the Trust and (b)
prepare and furnish (or cause to be prepared and furnished) to each Holder the
appropriate Internal Revenue Service form required to be provided or the
information required to be provided on such form. The Administrators shall
provide the Depositor and the Property Trustee with a copy of all such returns
and reports promptly after such filing or furnishing. The Trust and the
Administrators shall comply with United States Federal withholding and backup
withholding tax laws and information reporting requirements with respect to any
payments to Holders under the Trust Securities.

     Section 4.6. Payments under Indenture or Pursuant to Direct Actions.

     Any amount payable hereunder to any Holder of Preferred Securities (and any
Owner with respect thereto) shall be reduced by the amount of any corresponding
payment such Holder (and Owner) has directly received pursuant to Section 5.8 of
the Indenture or Section 5.13 of this Trust Agreement.

     Section 5.1. Initial Ownership.

     Upon the creation of the Trust and the contribution by the Depositor
pursuant to Section 2.3 and until the issuance of the Trust Securities, and at

be the sole beneficial owner of the Trust.

     Section 5.2. The Trust Securities Certificates.

     (a) The Preferred Securities Certificates shall be issued in minimum
denominations of $___ Liquidation Amount and integral multiples of $___ in
excess thereof, and the Common Securities Certificates shall be issued in
denominations of $___ Liquidation Amount and integral multiples of $___ in
excess thereof. The Trust Securities Certificates shall be executed on behalf of
the Trust by manual signature of at least one Administrator. Trust Securities
Certificates bearing the manual signatures of individuals who were, at the time
when such signatures shall have been affixed, authorized to sign on behalf of
the Trust, shall be validly issued and entitled to the benefits of this Trust
Agreement, notwithstanding that such individuals or any of them shall have
ceased to be so authorized prior to the delivery of such Trust Securities
Certificates or did not hold such offices at the date of delivery of such Trust
Securities Certificates. A transferee of a Trust Securities Certificate shall
become a Holder, and shall be entitled to the rights and subject to the
obligations of a Holder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.5
and 5.11.

     (b) Upon their original issuance, Preferred Securities Certificates shall
be issued in the form of one or more Global Preferred Securities registered in
the name of The Depository Trust Company, as Clearing Agency, or its nominee and
deposited with The Depository Trust Company or a custodian for The Depository
Trust Company for credit by The Depository Trust Company to the respective
accounts of the Owners thereof (or such other accounts as they may direct).

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

     Section 5.3. Execution and Delivery of Trust Securities Certificates.

Certificates, in an aggregate Liquidation Amount as provided in Sections 2.4 and

order of the Depositor, signed by an authorized Officer thereof, without further
corporate action by the Depositor, in authorized denominations.

     Section 5.4. Book-Entry Preferred Securities.

     (a) Each Global Preferred Security issued under this Agreement shall be
registered in the name of the Clearing Agency or a nominee thereof and delivered
to such Clearing Agency or a nominee thereof or custodian therefor, and each
such Global Preferred Security shall constitute a single Preferred Securities
Certificate for all purposes of this Agreement.

     (b) Notwithstanding any other provision in this Trust Agreement, no Global
Preferred Security may be exchanged in whole or in part for Preferred Securities
Certificates registered, and no transfer of a Global Preferred Security in whole
or in part may be registered, in the name of any Person other than the Clearing
Agency for such Global Preferred Security or a nominee thereof unless (i) the
Clearing Agency advises the Property Trustee in writing that the Clearing Agency
is no longer willing or able to properly discharge its responsibilities with
respect to the Global Preferred Security, and the Property Trustee is unable to
locate a qualified successor, (ii) the Trust at its option advises the
Depositary in writing that it elects to terminate the book-entry system through
the Clearing Agency, or (iii) a Debenture Event of Default has occurred and is
continuing. Upon the occurrence of any event specified in clause (i), (ii) or
(iii) above, the Administrators shall notify the Clearing Agency and instruct
the Clearing Agency to notify all Owners of Book-Entry Preferred Securities, the
Delaware Trustee and the Administrators of the occurrence of such event and of
the availability of the Definitive Preferred Securities Certificates to Owners
of the Preferred Securities requesting the same.

     (c) If any Global Preferred Security is to be exchanged for other Preferred
Securities Certificates or canceled in part, or if any other Preferred
Securities Certificate is to be exchanged in whole or in part for Book-Entry
Preferred Securities represented by a Global Preferred Security, then either (i)
such Global Preferred Security shall be so surrendered for exchange or
cancellation as provided in this Article V or (ii) the aggregate Liquidation
Amount represented by such Global Preferred Security shall be reduced, subject
to Section 5.2, or increased by an amount equal to the Liquidation Amount
represented by that portion of the Global Preferred Security to be so exchanged
or canceled, or equal to the Liquidation Amount represented by such other
Preferred Securities Certificates to be so exchanged for Book-Entry Preferred
Securities represented thereby, as the case may be, by means of an appropriate
adjustment made on the records of the Securities Registrar, whereupon the
Property Trustee, in accordance with the Applicable Procedures, shall instruct
the Clearing Agency or its authorized representative to make a corresponding
adjustment to its records. Upon surrender to the Administrators or the
Securities Registrar of the Global Preferred Security or Securities by the
Clearing Agency, accompanied by registration instructions, the Administrators,
or any one of them, shall execute the Definitive Preferred Securities
Certificates in accordance with the instructions of the Clearing Agency. None of
the Securities Registrar, the Issuer Trustees or the Administrators shall be
liable for any delay in delivery of such instructions and may conclusively rely
on, and shall be fully protected in relying on, such instructions. Upon the
issuance of Definitive Preferred Securities Certificates, the Issuer Trustees
and Administrators shall recognize the Holders of the Definitive Preferred
Securities Certificates as Holders. The Definitive Preferred Securities
Certificates shall be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to the Administrators, as evidenced
by the execution thereof by the Administrators or any one of them.

                                       22

     (d) Every Preferred Securities Certificate executed and delivered upon
registration or transfer of, or in exchange for or in lieu of, a Global
Preferred Security or any portion thereof, whether pursuant to this Article V or
Article IV or otherwise, shall be executed and delivered in the form of, and
shall be, a Global Preferred Security, unless such Preferred Securities
Certificate is registered in the name of a Person other than the Clearing Agency
for such Global Preferred Security or a nominee thereof.

     (e) The Clearing Agency or its nominee, as registered owner of a Global
Preferred Security, shall be the Holder of such Global Preferred Security for
all purposes under this Agreement and the Global Preferred Security, and Owners
with respect to a Global Preferred Security shall hold such interests pursuant
to the Applicable Procedures. The Securities Registrar and the Property Trustee
shall be entitled to deal with the Clearing Agency for all purposes of this
Trust Agreement relating to the Global Preferred Securities (including the
payment of the Liquidation Amount of and Distributions or directions by Owners
of Book-Entry Preferred Securities represented thereby) as the sole Holder of
the Book-Entry Preferred Securities represented thereby and shall have no
obligations to the Owners thereof. Neither of the Property Trustee nor the
Securities Registrar shall have any liability in respect of any transfers
effected by the Clearing Agency.

     The rights of the Owners of the Book-Entry Preferred Securities shall be
exercised only through the Clearing Agency and shall be limited to those
established by law, the Applicable Procedures and agreements between such Owners
and the Clearing Agency and/or the Clearing Agency Participants; provided, that,
solely for the purpose of determining whether the Holders of the requisite
amount of Preferred Securities have voted on any matter provided for in this
Trust Agreement, so long as Definitive Preferred Security Certificates have not
been issued, the Issuer Trustees may conclusively rely on, and shall be fully
protected in relying on, any written instrument (including a proxy) delivered to
the Property Trustee by the Clearing Agency setting forth the Owners' votes or
assigning the right to vote on any matter to any other Persons either in whole
or in part. Pursuant to the Certificate Depository Agreement, unless and until
Definitive Preferred Securities Certificates are issued pursuant to Section
5.4(b), the initial Clearing Agency will make book-entry transfers among the
Clearing Agency Participants and receive and transmit payments on the Preferred
Securities to such Clearing Agency Participants, and none of the Depositor, the
Administrators or the Issuer Trustees shall have any responsibility or
obligation with respect thereto.

     Section 5.5. Registration of Transfer and Exchange of Preferred Securities
Certificates.

     (a) The Property Trustee shall keep or cause to be kept, at its Corporate
Trust Office, a register or registers for the purpose of registering Trust
Securities Certificates and transfers and exchanges of Preferred Securities
Certificates (the "Securities Register") in which, the registrar designated by
the Depositor (the "Securities Registrar"), subject to such reasonable
regulations as it may prescribe, shall provide for the registration of Preferred
Securities Certificates and Common Securities Certificates (subject to Section
5.11 in the case of the Common Securities Certificates) and registration of
transfers and exchanges of Preferred Securities Certificates as herein provided.
The Property Trustee is hereby appointed Securities Registrar for the purpose of
registering Preferred Securities Certificates and (subject to Section 5.11)
Common Securities Certificates and transfers and exchanges thereof as provided
therein.

                                       23
<PAGE>   29

     Upon surrender for registration of transfer of any Preferred Securities
Certificate at the office or agency maintained pursuant to Section 5.9, the
Administrators or any one of them shall execute and deliver to the Property
Trustee, and the Property Trustee shall deliver in the name of the designated
transferee or transferees, one or more new Preferred Securities Certificates in
authorized denominations of a like aggregate Liquidation Amount dated the date
of execution by such Administrator.

     The Securities Registrar shall not be required to register the transfer of
any Preferred Securities that have been called for redemption. At the option of
a Holder, Preferred Securities Certificates may be exchanged for other Preferred
Securities Certificates in authorized denominations of the same class and of a
like aggregate Liquidation Amount upon surrender of the Preferred Securities
Certificates to be exchanged at the Corporate Trust Office.

     Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Securities Registrar duly
executed by the Holder or his attorney duly authorized in writing. Each
Preferred Securities Certificate surrendered for registration of transfer or
exchange shall be cancelled and subsequently disposed of by the Property Trustee
in accordance with its customary practice.

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

     (b) Notwithstanding any other provision of this Agreement, transfers and
exchanges of Preferred Securities Certificates and beneficial interests in a
Global Preferred Security of the kinds specified in this Section 5.5 shall be
made only in accordance with this Section 5.5.

     Section 5.6. Mutilated, Destroyed, Lost or Stolen Trust Securities
Certificates.

     If (a) any mutilated Trust Securities Certificate shall be surrendered to
the Securities Registrar, or if the Securities Registrar shall receive evidence
to its satisfaction of the destruction, lose or theft of any Trust Securities
Certificate and (b) there shall be delivered to the Securities Registrar and the
Administrators such security or indemnity as may be required by them to save
each of them harmless, then in the absence of notice that such Trust Securities
Certificate shall have been acquired by a bona fide purchaser, the
Administrators, or any one of them, on behalf of the Trust, shall execute and
make available for delivery, in exchange for or in lieu of any such mutilated,
destroyed, lost or stolen Trust Securities Certificate, a new Trust Securities
Certificate of like class, tenor and denomination. In connection with the
issuance of any new Trust Securities Certificate under this Section, the
Administrators or the Securities Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Trust Securities Certificate issued pursuant
to this Section shall constitute conclusive evidence of an undivided beneficial
ownership interest in the assets of the Trust, as if originally issued, whether
or not the lost, stolen or destroyed Trust Securities Certificate shall be found
at any time.

<PAGE>   30

     Section 5.7. Persons Deemed Holders.

     The Issuer Trustees, the Administrators and the Securities Registrar shall
each treat the Person in whose name any Trust Securities Certificate shall be
registered in the Securities Register as the owner of such Trust Securities
Certificate for the purpose of receiving distributions and for all other
purposes whatsoever, and none of the Issuer Trustees, the Administrators or the
Securities Registrar shall be bound by any notice to the contrary.

     Section 5.8. Access to List of Holders' Names and Addresses.

     At any time when the Property Trustee is not also acting as the Securities
Registrar, the Administrators or the Depositor shall furnish or cause to be
furnished to the Property Trustee (a) semi-annually on or before January 15 or
July 15 in each year, a list, in such form as the Property Trustee may
reasonably require, of the names and addresses of the Holders as of the most
recent regular record date (as provided in Section 4.1(d)) and (b) promptly
after receipt by any Administrator or the Depositor of a request therefor from
the Property Trustee, such other information as the Property Trustee may
reasonably require in order to enable the Property Trustee to discharge its
obligations under this Trust Agreement, in each case to the extent such
information is in the possession or control of the Administrators or the
Depositor and is not identical to a previously supplied list or has not
otherwise been received by the Property Trustee in its capacity as Securities
Registrar. The rights of Holders to communicate with other Holders with respect
to their rights under this Trust Agreement or under the Trust Securities, and
the corresponding rights of the Property Trustee shall be as provided in the
Trust Indenture Act. Each Holder, by receiving and holding a Trust Securities
Certificate, and each Owner shall be deemed to have agreed not to hold the
Depositor, the Property Trustee or the Administrators accountable by reason of
the disclosure of its name and address, regardless of the source from which such
information was derived.

     Section 5.9. Maintenance of Office or Agency.

     The Property Trustee shall designate, with the consent of the
Administrators (which shall not be unreasonably withheld), an office or offices
or agency or agencies where Preferred Securities Certificates may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Issuer Trustees in respect of the Trust Securities Certificates may be
served. The Property Trustee initially designates the Corporate Trust Office,
Attn: Corporate Trust Administration, as its principal corporate trust office
for such purposes. The Property Trustee shall give prompt written notice to the
Depositor and to the Holders of any change in the location of the Securities
Register or any such office or agency.

     Section 5.10. Appointment of Paying Agent.

     The Paying Agent shall make distributions to Holders from the Payment
Account and shall report the amounts of such distributions to the Property
Trustee and the Administrators. Any Paying Agent shall have the revocable power
to withdraw funds from the Payment Account for the purpose of making the
distributions referred to above. The Property Trustee may revoke such power and
remove the Paying Agent if it determines in its sole discretion that the Paying
Agent shall have failed to perform its obligations under this Trust Agreement in
any material

                                       25
<PAGE>   31

respect. The Paying Agent shall initially be the Bank. Any Person acting as
Paying Agent shall be permitted to resign as Paying Agent upon 30 days written
notice to the Property Trustee and the Depositor. In the event that the Bank
shall no longer be the Paying Agent or a successor Paying Agent shall resign or
its authority to act be revoked, the Property Trustee shall appoint a successor
that is reasonably acceptable to the Administrators to act as Paying Agent
(which shall be a bank or trust company). Such successor Paying Agent or any
additional Paying Agent shall execute and deliver to the Issuer Trustees an
instrument in which such successor Paying Agent or additional Paying Agent shall
agree with the Issuer Trustees that as Paying Agent, such successor Paying Agent
or additional Paying Agent will hold all sums, if any, held by it for payment to
the Holders in trust for the benefit of the Holders entitled thereto until such
sums shall be paid to such Holders. The Paying Agent shall return all unclaimed
funds to the Property Trustee and upon removal of a Paying Agent such Paying
Agent shall also return all funds in its possession to the Property Trustee. The
provisions of Sections 8.1, 8.3 and 8.6 herein shall apply, to the extent
applicable, to any other paying agent appointed hereunder. Any reference in this
Agreement to the Paying Agent shall include any co-paying agent unless the
context requires otherwise.

     Section 5.11. Ownership of Common Securities by Depositor.

     At each Closing Date, the Depositor shall acquire and retain beneficial and
record ownership of the Common Securities. To the fullest extent permitted by
law, other than transactions permitted by Sections 8.1 and 8.2 of the Indenture,
any attempted transfer of the Common Securities shall be void. The
Administrators shall cause each Common Securities Certificate issued to the
Depositor to contain a legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE
OTHER THAN IN ACCORDANCE WITH THE TRUST AGREEMENT (AS DEFINED BELOW)."

     Section 5.12. Notices to Clearing Agency.

     To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, for so long as Preferred Securities are
represented by a Global Preferred Security, the Administrators and the Issuer
Trustees shall give all such notices and communications specified herein to be
given to Owners to the Clearing Agency, and shall have no obligations to the
Owners.

     Section 5.13. Rights of Holders.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Holders shall not have any right or title therein other than the undivided
beneficial ownership interests in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. By acceptance of a
beneficial ownership interest in the Trust Securities, Holders agree to treat
the Debentures as indebtedness for all United States tax purposes. The Trust
Securities shall have no preemptive or similar rights and when issued and
delivered to Holders against payment of the purchase price therefor will be
fully paid and nonassessable by the Trust. The Holders of

                                       26
<PAGE>   32

the Trust Securities, in their capacities as such, shall be entitled to the same
limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware.

     (b) For so long as any Preferred Securities remain Outstanding, if, upon a
Debenture Event of Default, the Indenture Trustee fails or the holders of not
less than 25% in aggregate principal amount of the outstanding Debentures fail
to declare the principal of all of the Debentures to be immediately due and
payable, the Holders of at least 25% in aggregate Liquidation Amount of the
Preferred Securities then Outstanding shall have such right by a notice in
writing to the Depositor and the Indenture Trustee; and upon any such
declaration such principal amount of and the accrued interest on all of the
Debentures shall become immediately due and payable; provided, that the payment
of principal and interest on such Debentures shall remain subordinated to the
extent provided in the Indenture. At any time after such a declaration of
acceleration with respect to the Debentures has been made and before a judgment
or decree for payment of the money due has been obtained by the Indenture
Trustee as in the Indenture provided, the Holders of a majority in Liquidation
Amount of the Preferred Securities, by written notice to the Depositor and the
Indenture Trustee, may rescind and annul such declaration and its consequences
if:

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

               (A) all overdue installments of interest on all of the
               Debentures,

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

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

          (ii) all Events of Default with respect to the Debentures, other than
     the non-payment of the principal of the Debentures which has become due
     solely by such acceleration, have been cured or waived as provided in
     Section 5.13 of the Indenture.

     The Holders of a majority in aggregate Liquidation Amount of the Preferred
Securities may, on behalf of the Holders of all the Preferred Securities, waive
any past default under the Indenture, except a default in the payment of
principal or interest (unless such default has been cured and a sum sufficient
to pay all matured installments of interest and principal due otherwise than by
acceleration has been deposited with the Indenture Trustee) or a default in
respect of a covenant or provision which under the Indenture cannot be modified
or amended without the consent of the holder of each outstanding Debenture. No
such waiver or rescission shall affect any subsequent default or impair any
right consequent thereon. Upon receipt by the Property Trustee of written notice
declaring such an acceleration, or rescission and annulment thereof, by Holders
of the Preferred Securities all or part of which is represented by Book-Entry
Preferred

                                       27
<PAGE>   33

Securities Certificates, a record date shall be established for determining
Holders of Outstanding Preferred Securities entitled to join in such notice,
which record date shall be at the close of business on the day the Property
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day which is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice which has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.13(b).

     (c) For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section 5.1(a)
or 5.1(b) of the Indenture, any Holder of Preferred Securities shall have the
right to institute a proceeding directly against the Depositor, pursuant to the
Indenture, for enforcement of payment to such Holder of the principal amount of
or interest on Debentures having a principal amount equal to the Liquidation
Amount of the Preferred Securities of such Holder (a "Direct Action"). In
connection with any such Direct Action, the Holder of the Common Securities will
be subrogated to the rights of any Holder of the Preferred Securities to the
extent of any payment made by the Depositor to such Holder of Preferred
Securities as a result of such Direct Action. Except as set forth in subsection
(b) of this Section 5.13 and this subsection (c), the Holders of Preferred
Securities shall have no right to exercise directly any right or remedy
available to the holders of, or in respect of, the Debentures.

     (d) Except as otherwise provided in subsections (a), (b) and (c) of this
Section 5.13, the Holders of at least a majority in Liquidation Amount of the
Preferred Securities may, on behalf of the Holders of all the Preferred
Securities, waive any past default or Event of Default and its consequences.
Upon such waiver, any such default or Event of Default shall cease to exist, and
any default or Event of Default arising therefrom shall be deemed to have been
cured, for every purpose of this Trust Agreement, but no such waiver shall
extend to any subsequent or other default or Event of Default or impair any
right consequent thereon.

                                   ARTICLE VI

                        ACTS OF HOLDERS; MEETINGS; VOTING

     Section 6.1. Limitations on Voting Rights.

     (a) Except as provided in this Trust Agreement and in the Indenture and as
otherwise required by law, no Holder of Preferred Securities shall have any
right to vote or in any manner otherwise control the administration, operation
and management of the Trust or the obligations of the parties hereto, nor shall
anything herein set forth, or contained in the terms of the Trust

                                       28
<PAGE>   34

Securities Certificates, be construed so as to constitute the Holders from time
to time as partners or members of an association.

     (b) So long as any Debentures are held by the Property Trustee, the Issuer
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Indenture Trustee, or executing any
trust or power conferred on the Property Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 5.13 of
the Indenture, (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 or modification under Section 10.2 or termination of the Indenture
or any amendment, modification or termination of the Debentures, where such
consent shall be required, without, in each case, obtaining the prior approval
of the Holders of at least a majority in Liquidation Amount of all Outstanding
Preferred Securities; provided, however, that where a consent under the
Indenture would require the consent of each Holder of Debentures affected
thereby, no such consent shall be given by the Property Trustee without the
prior written consent of each Holder of Preferred Securities. The Property
Trustee shall not revoke any action previously authorized or approved by a vote
of the Holders of Preferred Securities, except by a subsequent vote of the
Holders of Preferred Securities. The Property Trustee shall notify all Holders
of the Preferred Securities of any notice of default received from the Indenture
Trustee with respect to the Debentures. In addition to obtaining the foregoing
approvals of the Holders of the Preferred Securities, prior to taking any of the
foregoing actions, the Issuer Trustees shall, at the expense of the Depositor,
obtain an Opinion of Counsel experienced in such matters to the effect that the
Trust will not be classified as an association taxable as a corporation for
United States Federal income tax purposes on account of such action.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Issuer Trustees otherwise propose to effect, (i) any action that would adversely
affect in any material respect the powers, preferences or special rights of the
Preferred Securities, whether by way of amendment to the Trust Agreement or
otherwise, or (ii) the dissolution, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Preferred Securities as a class will be entitled to vote on such
amendment or proposal and such amendment or proposal shall not be effective
except with the approval of the Holders of at least a majority in Liquidation
Amount of the Outstanding Preferred Securities. Notwithstanding any other
provision of this Trust Agreement, no amendment to this Trust Agreement may be
made if, as a result of such amendment, the Trust would be classified as an
association taxable as a corporation for United States Federal income tax
purposes.

     Section 6.2. Notice of Meetings.

     Notice of all meetings of the Holders of Preferred Securities, stating the
time, place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 10.8 to each Holder of Preferred Securities of record, at
his registered address, at least 15 days and not more than 90 days before the
meeting. At any such meeting, any business properly before the meeting may be so
considered whether or not stated in the notice of the meeting. Any adjourned
meeting may be held as adjourned without further notice.

<PAGE>   35

     Section 6.3. Meetings of the Holders of Preferred Securities.

     No annual meeting of Holders is required to be held. The Property Trustee,
however, shall call a meeting of Holders to vote on any matter upon the written
request of the Holders of record of 25% in aggregate Liquidation Amount of the
Preferred Securities and the Administrators or the Property Trustee may, at any
time in their discretion, call a meeting of Holders of Preferred Securities to
vote on any matters as to which Holders of Preferred Securities are entitled to
vote.

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

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

     Section 6.4. Voting Rights.

     Holders shall be entitled to one vote for each $____ of Liquidation Amount
represented by their Outstanding Trust Securities in respect of any matter as to
which such Holders are entitled to vote.

     Section 6.5. Proxies, etc.

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

     Section 6.6. Holder Action by Written Consent.

     Any action which may be taken by Holders at a meeting may be taken without
a meeting if Holders holding a majority of all Outstanding Trust Securities
(based upon their Liquidation Amount) entitled to vote in respect of such action
(or such larger proportion thereof as shall be required by any express provision
of this Trust Agreement) shall consent to the action in writing.

     Section 6.7. Record Date for Voting and Other Purposes.

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

     Section 6.8. Acts of Holders.

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

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

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

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

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

                                       31
<PAGE>   37

     If any dispute shall arise among the Holders, the Administrators and the
Issuer Trustees with respect to the authenticity, validity or binding nature of
any request, demand, authorization, direction, consent, waiver or other Act of
such Holder, Administrator or Issuer Trustee under this Article VI, then the
determination of such matter by the Property Trustee shall be conclusive with
respect to such matter.

     Section 6.9. Inspection of Records.

     Upon reasonable notice to the Administrators and the Property Trustee, the
records of the Trust shall be open to inspection by Holders during normal
business hours for any purpose reasonably related to such Holder's interest as a
Holder.

Trust or would question the right, power and authority of the Property Trustee
or the Delaware Trustee, as the case may be, to enter into or perform its
obligations as one of the Issuer Trustees under this Trust Agreement.

                                  ARTICLE VIII

                     THE ISSUER TRUSTEES; THE ADMINISTRATORS

     Section 8.1. Certain Duties and Responsibilities.

     (a) The duties and responsibilities of the Issuer Trustees and the
Administrators shall be as provided by this Trust Agreement and, in the case of
the Property Trustee, subject to the Trust Indenture Act. Notwithstanding the
foregoing, no provision of this Trust Agreement shall require any of the Issuer
Trustees or the Administrators to expend or risk their own funds or otherwise
incur any financial liability in the performance of any of their duties
hereunder, or in the exercise of any of their rights or powers, if they shall
have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Issuer Trustees or the Administrators shall be subject to the
provisions of this Section. Nothing in this Trust Agreement shall be construed
to release an Issuer Trustee or an Administrator from liability for its own
gross negligent action, its own gross negligent failure to act, or its own
willful misconduct. To the extent that, at law or in equity, an Administrator or
Issuer Trustee has duties (including fiduciary duties) and liabilities relating
thereto to the Trust or to the Holders, such Administrator or the Issuer Trustee
shall not be liable to the Trust or to any Holder for its good faith reliance on
the provisions of this Trust Agreement. The provisions of this Trust Agreement,
to the extent that they restrict the duties and liabilities of the
Administrators or Issuer Trustees otherwise existing at law or in equity, are
agreed by the Depositor and the Holders to replace such other duties and
liabilities of the Administrators and Issuer Trustees.

     (b) All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the Property Trustee or a Paying
Agent to make payments in accordance with the terms hereof. Each Holder, by its
acceptance of a Trust Security, agrees that it will look solely to the revenue
and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that none of the Administrators or the
Issuer Trustees are personally liable to it for any amount distributable in
respect of any Trust Security or for any other liability in respect of any Trust
Security. This Section 8.1(b) does not limit the liability of the Issuer
Trustees or the Administrators expressly set forth elsewhere in this Trust
Agreement and, in the case of the Property Trustee, in the Trust Indenture Act.

     (c) If an Event of Default has occurred and is continuing, the Property
Trustee shall enforce this Trust Agreement for the benefit of the Holders.

     (d) 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
Trust Agreement (including pursuant to Section 10.10), and no implied covenants
shall be read into this Trust Agreement against the Property Trustee. If an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 5.13), the Property Trustee shall exercise such of the rights and powers
vested in it by this Trust

                                       34
<PAGE>   40

Agreement and use the same degree of care and skill in its exercise thereof as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

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

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

          (ii) 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 Preferred 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 Trust Agreement;

          (iii) the Property Trustee's sole duty with respect to the custody,
     safe keeping and physical preservation of the Debentures and the Payment
     Account shall be to deal with such Property in 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 Trust Agreement and the Trust Indenture Act;

          (iv) 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;
     and money held by the Property Trustee need not be segregated from other
     funds held by it except in relation to the Payment Account maintained by
     the Property Trustee pursuant to Section 3.1 and except to the extent
     otherwise required by law;

          (v) the Property Trustee shall not be responsible for monitoring the
     compliance by the Delaware Trustee, the Administrators or the Depositor
     with their respective duties under this Trust Agreement, nor shall the
     Property Trustee be liable for the default or misconduct of the Delaware
     Trustee, the Administrators or the Depositor;

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

               (A) the duties and obligations of the Property Trustee shall be
               determined solely by the express provisions of this Trust
               Agreement (including pursuant to Section 10.10), and the Property
               Trustee shall not be liable except for the performance of such
               duties and obligations as are specifically set forth in this
               Trust Agreement (including pursuant to Section 10.10); 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

                                       35
<PAGE>   41

               requirements of this Trust Agreement; but in the case of any such
               certificates or opinions that by any provision hereof or of the
               Trust Indenture Act 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 Trust Agreement; and

          (vii) subject to Section 8.1(c), no provision of this Trust Agreement
     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, if the
     Property Trustee shall have reasonable grounds for believing that the
     repayment of such funds or liability is not reasonably assured to it under
     the terms of the Trust Agreement or indemnity reasonably satisfactory to it
     against such risk or liability is not reasonably assured to it.

     (f) The Administrators shall not be responsible for monitoring the
compliance by the Issuer Trustees or the Depositor with their respective duties
under this Trust Agreement, nor shall any Administrator be liable for the
default or misconduct of any other Administrator, the Issuer Trustees or the
Depositor.

     (g) No provision of this Trust Agreement shall be deemed to impose any duty
or obligation on any Issuer Trustee or Administrator 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 such Person 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 any Issuer Trustee or Administrator
shall be construed to be a duty.

     Section 8.2. Certain Notices.

     Within 90 days after the occurrence of any Event of Default actually known
to the Property Trustee, the Property Trustee shall transmit, in the manner and
to the extent provided in Section 10.8, notice of such Event of Default to the
Holders, the Administrators and the Depositor, unless such Event of Default
shall have been cured or waived.

     Within five Business Days after the receipt of notice of the Depositor's
exercise of its right to defer the payment of interest on the Debentures
pursuant to the Indenture, the Property Trustee shall transmit, in the manner
and to the extent provided in Section 10.8, notice of such exercise to the
Holders and the Administrators, unless such exercise shall have been revoked.

     Section 8.3. Certain Rights of Property Trustee.

     Subject to the provisions of Section 8.1:

     (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond, debenture, note, other
evidence

                                       36
<PAGE>   42

of indebtedness or other paper or document believed by it to be genuine and to
have been signed or presented by the proper party or parties;

     (b) if (i) in performing its duties under this Trust Agreement, the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement, the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the Holders of Preferred Securities are entitled to vote under the terms of this
Trust Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within ten
Business Days after it has delivered such notice, or such reasonably shorter
period of time set forth in such notice (which to the extent practicable shall
not be less than two Business Days), it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Trust Agreement as
it shall deem advisable and in the best interests of the Holders, in which event
the Property Trustee shall have no liability except for its own bad faith,
negligence or willful misconduct;

     (c) any direction or act of the Depositor contemplated by this Trust

or registration of any instrument (including any financing or continuation
statement or any filing under tax or securities laws) or any rerecording,
refiling or reregistration thereof;

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

     (g) the Property Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Holders pursuant to this Trust Agreement, unless such
Holders shall have offered to the Property Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by
it in compliance with such request or direction; provided, that nothing
contained in this Section 8.3(g) shall be taken to relieve the Property Trustee,
upon the occurrence of an Event

                                       37
<PAGE>   43

of Default, of its obligation to exercise the rights and powers vested in it by
this Trust Agreement;

     (h) the Property Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,

matters as it may see fit;

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

     (j) whenever in the administration of this Trust Agreement 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 Trust Securities
which instructions may only be given by the Holders of the same proportion in
Liquidation Amount of the Trust Securities as would be entitled to direct the
Property Trustee under the terms of the Trust Securities in respect of such
remedy, right or action, (ii) may refrain from enforcing such remedy or right or
taking such other action until such instructions are received and (iii) shall be
protected in acting in accordance with such instructions; and

     (k) except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement.

     No provision of this Trust Agreement 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

     Section 8.5. May Hold Securities.

     Any Administrator, any Issuer Trustee or any other agent of any Trustee or
the Trust, in its individual or any other capacity, may become the owner or
pledgee of Trust Securities and, subject to Sections 8.8 and 8.13 and except as
provided in the definition of the term "Outstanding" in Article I, may otherwise

     Pursuant to the Indenture, the Depositor, as borrower, agrees:

     (a) to pay to each Issuer Trustee and Paying Agent from time to time

     (b) except as otherwise expressly provided herein, to reimburse each Issuer
Trustee upon request for all reasonable expenses, disbursements and advances
incurred or made by such Issuer Trustee in accordance with any provision of this

penalty, expense or claim of any kind or nature whatsoever incurred by such
Indemnified Person by reason of the creation, operation or termination of the
Trust or any act or omission performed or omitted by such Indemnified Person in
good faith on behalf of the Trust and in a manner such Indemnified Person
reasonably believed to be within the scope of authority conferred on such
Indemnified Person by this Trust Agreement, except that no Indemnified Person
shall be entitled to be indemnified in respect of any loss, damage or claim
incurred by such Indemnified Person by reason of gross negligence or willful
misconduct with respect to such acts or omissions.

     (d) to the fullest extent permitted by applicable law, to advance expenses
(including reasonable legal fees) incurred by an Indemnified Person in defending
any claim, demand, action, suit or proceeding, from time to time, prior to the
final disposition of such claim, demand, action, suit or proceeding upon receipt

Person of its or his good faith belief that it or he has met the standard of
conduct set forth in this Section 8.6 and (ii) an undertaking by or on behalf of
the Indemnified Person to repay such amount if it shall be determined that the
Indemnified Person is not entitled to be indemnified as authorized in the
preceding subsection.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement or the resignation or removal of any Trustee.

                                       39
<PAGE>   45

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

     In the event that the Property Trustee is also acting as Paying Agent or

Paying Agent or Securities Registrar.

     Section 8.7. Corporate Property Trustee Required; Eligibility of Issuer
Trustees and Administrators.

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

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

     (c) There shall at all times be a Delaware Trustee with respect to the

     Section 8.8. Conflicting Interests.

     If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement. The Depositor, any Administrator, any Paying Agent and any Issuer
Trustee may engage in or possess an interest in other business ventures of any
nature or description, independently or with others, similar or dissimilar to
the business of the Trust, and the Trust and the Holders of Trust Securities
shall have no rights by virtue of this Trust Agreement 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 Administrator,
any Paying Agent nor any Issuer Trustee shall be obligated to present any
particular investment or other opportunity to the Trust even if such opportunity
is of a character that, if presented to the Trust, could be taken by the Trust,
and the Depositor, any Administrator, any Paying Agent or any Issuer 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 Issuer Trustee or

                                       40
<PAGE>   46

any Paying Agent may engage or be interested in any financial or other
transaction with the Depositor or any Affiliate of the Depositor, or may act as
depository for, trustee or agent for, or act on any committee or body of holders
of, securities or other obligations of the Depositor or its Affiliates.

     Section 8.9. Co-Trustees and Separate Trustee.

     Unless an Event of Default shall have occurred and be continuing, at any
time or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Property Trustee shall have power to appoint, and
upon the written request of the Property Trustee the Depositor and the
Administrators shall for such purpose join with the Property Trustee in the
execution, delivery and performance of all instruments and agreements necessary
or proper to appoint, one or more Persons either to act as co-trustee jointly
with the Property Trustee of all or any part of such Trust Property or, to the
extent required by law, to act as separate trustee of any such property, in
either case with such powers as may be provided in the instrument of
appointment, and to vest in such Person or Persons in the capacity aforesaid,
any property, title, right or power deemed necessary or desirable, subject to
the other provisions of this Section. Any co-trustee or separate trustee
appointed pursuant to this Section shall either be (i) a natural person who is
at least 21 years of age and a resident of the United States or (ii) a legal
entity with its principal place of business in the United States that shall act
through one or more persons authorized to bind such entity.

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

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

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

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

                                       41
<PAGE>   47

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

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

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

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

     Section 8.10. Resignation and Removal of Issuer Trustees, Appointment of
Successor.

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

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

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

     If either Issuer Trustee shall resign, be removed or become incapable of
acting as Property Trustee or Delaware Trustee, as the case may be, or if a
vacancy shall occur in the office of any Issuer Trustee for any cause, at a time
when no Debenture Event of Default shall have occurred and be continuing, the
Depositor, by Act delivered to the Relevant Trustee, shall promptly appoint a
successor Issuer Trustee or Trustees, and the Relevant Trustee shall comply with
the applicable requirements of Section 8.11. If either Issuer Trustee shall
resign, be removed or become incapable of continuing to act as the Property
Trustee or the Delaware Trustee, as the case may be, at a time when a Debenture
Event of Default shall have occurred

                                       42
<PAGE>   48

and be continuing, the Holders of the Preferred Securities, by Act of the
Holders of a majority in Liquidation Amount of the Preferred Securities then
Outstanding delivered to the retiring Relevant Trustee, shall promptly appoint a
successor Relevant Trustee or Trustees, and such successor Trustee shall comply
with the applicable requirements of Section 8.11.

     The Property Trustee shall give notice of each resignation and each removal
of an Issuer Trustee and each appointment of a successor Issuer Trustee to all
Holders in the manner provided in Section 10.8 and shall give notice to the
Depositor and the Administrators. Each notice shall include the name of the
successor Relevant Trustee and the address of its Corporate Trust Office if it
is the Property Trustee.

     Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event a Delaware Trustee who is a natural person dies or
becomes, in the opinion of the Depositor, incompetent or incapacitated, the
vacancy created by such death, incompetence or incapacity may be filled by the
Property Trustee (with the successor in each case being a Person who satisfies
the eligibility requirement for Delaware Trustee set forth in Section 8.7).

     Section 8.11. Acceptance of Appointment by Successor.

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

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

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

be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such Relevant
Trustee shall be a party, or any corporation succeeding to all or substantially
all the corporate trust business of such Relevant Trustee, shall be the
successor of such Relevant Trustee hereunder, provided such corporation 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.

     Section 8.13. Preferential Collection of Claims Against Depositor or Trust.

     If and when the Property Trustee or the Delaware Trustee shall be or become
a creditor of the Depositor or the Trust (or any other obligor upon the

Trustee, as the case may be, shall be subject to and shall take all actions
necessary in order to comply with the provisions of the Trust Indenture Act
regarding the collection of claims against the Depositor or Trust (or any such
other obligor).

     Section 8.14. Reports by the Property Trustee.

     (a) The Property Trustee shall transmit to Holders such reports concerning
the Property Trustee and its actions under this Trust Agreement as may be
required pursuant to the Trust Indenture Act at the times and in the manner

Act, the Property Trustee shall, within sixty days after each May 15th following
the date of this Trust Agreement deliver to Holders a brief report, dated as of
such May 15, which complies with the provisions of such Section 313(a).

     (b) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with each national stock exchange, the
NASDAQ National Market or such other interdealer quotation system or
self-regulatory organization upon which the Trust Securities are listed or
traded, with the Commission and with the Depositor.

     Section 8.15. Reports to the Property Trustee.

     The Depositor and the Administrators on behalf of the Trust shall provide
to the Property Trustee such documents, reports and information as required by
Section 314 of the Trust Indenture Act (if any) and the compliance certificate
required by Section 314(a) of the Trust Indenture Act in the form, in the manner
and at the times required by Section 314 of the Trust Indenture Act.

Trustee and the Delaware Trustee may be the same Person, subject to the
applicable eligibility requirements set forth herein.

     (b) If an Issuer Trustee ceases to hold office for any reason, or if the
number of Issuer Trustees is increased pursuant to Section 8.17(a), a vacancy
shall occur. The vacancy shall be filled with an Issuer Trustee appointed in
accordance with Section 8.10.

     (c) The death, resignation, retirement, removal, bankruptcy, incompetence

     Section 9.4. Liquidation.

     (a) If an Early Termination Event specified in clause (a), (b) or (d) of
Section 9.2 occurs or upon the Expiration Date, the Trust shall be liquidated by
the Property Trustee as expeditiously as the Property Trustee determines to be
possible by distributing, after satisfaction of liabilities to creditors of the
Trust as provided by applicable law, to each Holder a Like Amount of Debentures,
subject to Section 9.4(d). Notice of liquidation shall be given by the Property
Trustee by first-class mail, postage prepaid mailed not later than 30 nor more
than 60 days prior to the Liquidation Date to each Holder of Trust Securities at
such Holder's address appearing in the Securities Register. All notices of
liquidation shall:

          (i) state the Liquidation Date;

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

          (iii) provide such information with respect to the mechanics by which
     Holders may exchange Trust Securities Certificates for Debentures, or if
     Section 9.4(d) applies, receive a Liquidation Distribution, as the Property
     Trustee (after consultation with the Administrators) shall deem
     appropriate.

     (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Holders, the
Property Trustee shall establish a record date for such distribution (which
shall be not more than 45 days prior to the Liquidation Date) and, either itself
acting as exchange agent or through the appointment of a separate exchange
agent, shall establish such procedures as it shall deem appropriate to effect
the distribution of Debentures in exchange for the Outstanding Trust Securities

reasonable efforts to have the Debentures listed on the New York Stock Exchange
or on such other exchange, interdealer quotation system or self-regulatory
organization as the Preferred Securities are then listed, (iv) any Trust
Securities Certificates not so surrendered for exchange will be deemed to
represent a Like Amount of Debentures, accruing interest at the rate provided
for in the Debentures from the last Distribution Date on which a Distribution
was made on such Trust Securities Certificates until such certificates are so
surrendered (and until such certificates are so surrendered, no payments of
interest or principal will be made to Holders of Trust Securities Certificates
with respect to such Debentures) and (v) all rights of Holders holding Trust
Securities will cease, except the right of such Holders to receive Debentures
upon surrender of Trust Securities Certificates.

     (d) In the event that, upon the Expiration Date or the occurrence of an
Early Termination Event, notwithstanding the other provisions of this Section
9.4, whether because of an order for dissolution entered by a court of competent
jurisdiction or otherwise, distribution of

                                       47
<PAGE>   53

the Debentures in the manner provided herein is determined by the Property
Trustee not to be practical, the Trust Property shall be liquidated, and the
Trust shall be wound-up by the Property Trustee in such manner as the Property
Trustee determines. In such event, 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 Liquidation Amount per Trust Security plus
accumulated and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"). If, upon any such winding-up, the
Liquidation Distribution can be paid only in part because the Trust has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then, subject to the next succeeding sentence, the amounts payable
by the Trust on the Trust Securities shall be paid on a pro rata basis (based
upon Liquidation Amounts). The Holder of the Common Securities will be entitled
to receive Liquidation Distributions upon any such winding-up pro rata
(determined as aforesaid) with Holders of Preferred Securities, except that, if
a Debenture Event of Default has occurred and is continuing, the Preferred
Securities shall have a priority over the Common Securities.

     (e) Upon the completion of the liquidation of the Trust, the Property
Trustee shall file a certificate of cancellation with the Secretary of State in
the State of Delaware and the Trust shall terminate.

     Section 9.5. Mergers, Consolidations, Conversions, Amalgamations or
Replacements of the Trust.

     The Trust may not merge with or into, consolidate, convert into,
amalgamate, be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, except pursuant to this
Section 9.5 or Section 9.4. At the request of the Holders of at least a majority
in Liquidation Amount of the Common Securities, with the consent of the Holders
of at least a majority in Liquidation Amount of the Preferred Securities but
without the consent of the Issuer Trustees, the Trust may merge with or into,
consolidate, convert into, amalgamate, be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any State; provided, that (a) such successor
entity either (i) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (ii) substitutes for the Preferred

distributions and payments upon liquidation, redemption and otherwise, (b) the
Depositor expressly appoints a trustee of such successor entity possessing the
same powers and duties as the Property Trustee as the holder of the Debentures,
(c) the Successor Securities are listed or traded, or any Successor Securities
will be listed upon notification of issuance, on any national securities
exchange or other organization on which the Preferred Securities are then listed

replacement, conveyance, transfer or lease, the Property Trustee has received an
Opinion of Counsel to the effect that (i) such merger, consolidation,
conversion, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the Holders of the
Preferred Securities (including any Successor Securities) in any material
respect, (ii) following such merger, consolidation, conversion, amalgamation,

entity will be required to register as an investment company under the 1940 Act

to be classified as an association that is taxable as a corporation for U.S.

successor entity under the Successor Securities at least to the extent provided

Securities, consolidate, amalgamate, merge with or into, convert into, be
replaced by or convey, transfer or lease its properties and assets substantially
as an entirety to any other Person or permit any other entity to consolidate,
amalgamate, merge with or into, or replace it if such consolidation, conversion,
amalgamation, merger, replacement, conveyance, transfer or lease would cause the

United States Federal income tax purposes.

other provisions with respect to matters or questions arising under this Trust

classified as a grantor trust for United States Federal income tax purposes.

Attention: General Counsel's Office

          Re: HCC Capital Trust I ____% Trust Preferred Securities

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the
book-entry-only portion of the ____% Trust Preferred Securities (the "Preferred
Securities"), of HCC Capital Trust I, a Delaware business trust (the "Issuer"),
formed pursuant to a Trust Agreement between HCC Insurance Holdings, Inc.
("HCC"), First Union National Bank, as Property Trustee, First Union Trust
Company, N.A., as Delaware Trustee, the several Holders named therein. The
payment of distributions on the Preferred Securities, and payments due upon
liquidation of Issuer or redemption of the Preferred Securities, to the extent
the Issuer has funds available for the payment thereof are guaranteed by HCC to
the extent set forth in a Guarantee Agreement dated _________, 2000, by HCC with
respect to the Preferred Securities. HCC and the Issuer propose to sell the
Preferred Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement dated ______________, 2000 by and among the Underwriters,
the Issuer and HCC, and the Underwriters wish to take delivery of the Preferred
Securities through DTC. First Union National Bank, is acting as transfer agent
and registrar with respect to the Preferred Securities (then "Transfer Agent and
Registrar").

     To induce DTC to accept the Preferred Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Preferred
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:

     1. Prior to the closing of the sale of the Preferred Securities to the
Underwriters, which is expected to occur on or about _________, 2000, there
shall be deposited with or on behalf of DTC one or more global certificates
(individually and collectively, the "Global Certificate") registered in the name
of DTC's Preferred Securities nominee, Cede & Co., representing an aggregate of
___________ Preferred Securities and bearing the following legend:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO ISSUER OR ITS AGENT
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL

                                      B-1

15 calendar days in advance of such record date.

     3. In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4. In the event of distribution on, or an offering or issuance of rights
with respect to, the Preferred Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice specifying: (a) the amount
of and conditions, if any, applicable to the payment of any such distribution or
any such offering or issuance of rights; (b) any applicable expiration or
deadline date, or any date by which any action on the part of the holders of
Preferred Securities is required; and (c) the date any required notice is to be
mailed by or on behalf of the Issuer to holders of Preferred Securities or

"Publication Date"). Such notice shall be sent to DTC by a secure means (e.g.,
legible telecopy, registered or certified mail, overnight delivery) in a timely
manner designed to assure that such notice is in DTC's possession no later than
the close of business on the business day before the Publication Date. The
Issuer or the Transfer Agent and Registrar will forward such notice either in a
separate secure transmission for each CUSIP number or in a secure transmission
of multiple CUSIP numbers (if applicable) that includes a manifest or list of
each CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Preferred Securities. After establishing the amount of payment to be made on the

or address to which notices or payments may be sent.

invitation) necessitating a reduction in the aggregate number of Preferred
Securities outstanding evidenced by Global Certificates, DTC, in its discretion:
(a) may request the Issuer or the Transfer Agent and Registrar to issue and
countersign a new Global Certificate; or (b) may make an appropriate notation on
the Global Certificate indicating the date and amount of such reduction.

     11. DTC may discontinue its services as a securities depositary with
respect to the Preferred Securities at any time by giving at least 90 days'
prior written notice to the Issuer and the Transfer Agent and Registrar (at
which time DTC will confirm with the Issuer or the Transfer Agent and Registrar
the aggregate number of Preferred Securities deposited with it) and discharging
its responsibilities with respect thereto under applicable law. Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Preferred Securities, make available one or more
separate global certificates evidencing Preferred Securities to any Participant
having Preferred Securities credited to its DTC account, or issue definitive
Preferred Securities to the beneficial holders thereof, and in any such case,
DTC agrees to cooperate fully with the Issuer and the Transfer Agent and
Registrar, and to return the Global Certificate, duly endorsed for transfer as
directed by the Issuer or the Transfer Agent and Registrar, together with any
other documents of transfer reasonably requested by the Issuer or the Transfer
Agent and Registrar.

     12. In the event that the Issuer determines that beneficial owners of
Preferred Securities shall be able to obtain definitive Preferred Securities,
the Issuer or the Transfer Agent and Registrar shall notify DTC of the
availability of certificates. In such event, the Issuer or the Transfer Agent
and Registrar shall issue, transfer and exchange certificates in appropriate
amounts, as required by DTC and others, and DTC agrees to cooperate fully with
the Issuer and the Transfer Agent and Registrar and to return the Global
Certificate, duly endorsed for transfer as directed by the Issuer or the
Transfer Agent and Registrar, together with any other documents of transfer
reasonably requested by the Issuer or the Transfer Agent and Registrar.

     13. This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument. Nothing
herein shall be deemed to require the Transfer Agent and Registrar to advance
funds on behalf of HCC Capital Trust I.
