                                  ----------
 
  This Prospectus relates to the 6 3/4% Convertible Quarterly Income Preferred
securities (the "Preferred Securities") which represent preferred undivided
beneficial interests in the assets of Host Marriott Financial Trust, a
statutory business trust created under the laws of the State of Delaware (the
"Issuer"), and the shares of common stock, par value $1.00 per share (the "Host
Marriott Common Stock"), of Host Marriott Corporation, a Delaware corporation
("Host Marriott" or the "Company"), issuable upon conversion of the Preferred
Securities. The Preferred Securities were issued and sold (the "Original
Offering") on December 2, 1996 (the "Original Offering Date") to the Initial
Purchasers (as defined herein) and were simultaneously sold by the Initial
Purchasers in transactions exempt from the registration requirements of the
Securities Act of 1933, as amended (the "Securities Act"), in the United States
to persons reasonably believed by the Purchasers to be qualified institutional
buyers as defined in Rule 144A under the Securities Act, and outside the United
States to non-U.S. persons in offshore transactions in reliance on Regulation S
under the Securities Act. All of the beneficial interests in the assets of the
Issuer represented by common securities of the Issuer (the "Common Securities"
and, together with the Preferred Securities, the "Trust Securities") are owned
by Host Marriott Corporation. The Issuer exists for the sole purpose of issuing
the Preferred Securities and the Common Securities and investing the proceeds
from the issuance thereof in 6 3/4% Convertible Subordinated Debentures due
December 2, 2026 (the "Debentures") to be issued by Host Marriott. The
Preferred Securities have a preference under certain circumstances with respect
to cash distributions and amounts payable on liquidation, redemption or
otherwise over the Common Securities. See "Description of the Preferred
Securities--Subordination of Common Securities."
 
  The Preferred Securities and Host Marriott Common Stock issuable upon
conversion of the Preferred Securities (collectively the "Offered Securities")
may be offered and sold from time to time by the holders named herein or by
their transferees, pledgees, donees or their successors (collectively, the
"Selling Holders") pursuant to this Prospectus. The Offered Securities may be
sold by the Selling Holders from time to time directly to purchasers or through
agents, underwriters or dealers. See "Selling Holders" and "Plan of
Distribution." If required, the names of any such agents or underwriters
involved in the sale of the Offered Securities and the applicable agent's
commission, dealer's purchase price or underwriter's discount, if any, will be
set forth in an accompanying supplement to this Prospectus (the "Prospectus
Supplement"). The Selling Holders will receive all of the net proceeds from the
sale of the Offered Securities and will pay all underwriting discounts, selling
commissions and transfer taxes, if any, applicable to any such sale. Host
Marriott is responsible for payment of all other expenses incident to the
registration of the Offered Securities. The Selling Holders and any broker-
dealers, agents or underwriters that participate in the distribution of the
Offered Securities may be deemed to be "underwriters" within the meaning of the
Securities Act, and any commission received by them and any profit on the
resale of the Offered Securities purchased by them may be deemed to be
underwriting commissions or discounts under the Securities Act. See "Plan of
Distribution" for a description of indemnification arrangements.
 
  Each Preferred Security is convertible in the manner described herein at the
option of the holder, at any time prior to the Conversion Expiration Date (as
defined herein), into shares of common stock, $1.00 par value per share, of
Host Marriott Common Stock at the rate of 2.6876 shares of Host Marriott Common
Stock for each Preferred Security (equivalent to a conversion price of $18.604
per share of Host Marriott Common Stock), subject to adjustment in certain
circumstances. See "Description of the Preferred Securities--Conversion Rights"
and "Description of Host Marriott Capital Stock." The last reported sale price
of Host Marriott Common Stock, which is listed under the symbol "HMT" on the
New York Stock Exchange, on January 15, 1997 was $16 5/8 per share.
 
  Holders of the Preferred Securities are entitled to receive preferential
cumulative cash distributions from the Issuer at an annual rate of 6 3/4% of
the liquidation preference of $50 per Preferred Security accruing from the date
of original issuance and payable quarterly in arrears on March 1, June 1,
September 1 and December 1 of each year, commencing March 1, 1997. See
"Description of the Preferred Securities--Distributions". The payment of
distributions out of moneys held by the Trust and payments on liquidation of
the Trust or the redemption of Preferred Securities, as described below, are
guaranteed by Host Marriott (the "Guarantee") to the extent the Trust has funds
available therefor as described under "Description of the Guarantee". The
Guarantee, when taken together with its obligations under the Indenture (as
defined herein) pursuant to which the Debentures were issued, the Debentures
and its obligations under the Trust Agreement (as defined herein), including
its obligations under the Indenture to pay costs, expenses, debts and
liabilities of the Trust (other than with respect to the Trust Securities),
provide a full and unconditional guarantee of amounts due on the Preferred
Securities. Host Marriott's obligations under the Guarantee rank (i)
subordinate and junior to all other liabilities of Host Marriott except any
liabilities that may be pari passu by their terms, (ii) pari passu with the
most senior preferred stock issued from time to time by Host Marriott and with
any guarantee now or hereafter entered into by Host Marriott in respect of any
preferred or preference stock or any preferred securities of any affiliate of
Host Marriott and (iii) senior to Host Marriott Common Stock. See "Description
of the Guarantee".The distribution rate and the distribution and other payment
dates for the Preferred Securities correspond to the interest rate and interest
and other payment dates in the Debentures, which are the sole assets of the
Issuer. As a result, if principal or interest is not paid on the Debentures, no
amounts will be paid on the Preferred Securities.
 
  Host Marriott has the right to defer payment of interest on the Debentures at
any time or from time to time for a period not exceeding 20 consecutive
quarters with respect to each deferral period (each, an "Extension Period"),
provided that no Extension Period may extend beyond the stated maturity of the
Debentures. Upon the termination of any such Extension Period and the payment
of all amounts then due on any Interest Payment Date (as defined herein), Host
Marriott may elect to begin a new Extension Period subject to the requirements
set forth herein. If interest payments on the Debentures are so deferred,
Distributions on the Preferred Securities will also be deferred and Host
Marriott will not be permitted, subject to certain exceptions set forth herein,
to declare or pay any cash distributions with respect to Host Marriott's
capital stock or debt securities that rank pari passu with or junior to the
Debentures.
                                                           (Continued on page 2)
 
 
                                  ----------
  PROSPECTIVE INVESTORS SHOULD CAREFULLY CONSIDER THE MATTERS DISCUSSED UNDER
THE CAPTION "RISK FACTORS" BEGINNING ON PAGE 4.
 
                                  ----------
THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE  SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
  AND EXCHANGE COMMISSION OR ANY  STATE SECURITIES COMMISSION PASSED UPON THE
  ACCURACY  OR  ADEQUACY  OF  THIS  PROSPECTUS.  ANY  REPRESENTATION  TO  THE
   CONTRARY IS A CRIMINAL OFFENSE.

(Continued from page 1)
 
  During an Extension Period, interest on the Debentures will continue to
accrue (and the amount of Distributions to which holders of the Preferred
Securities are entitled will accumulate at 6 3/4% per annum, compounded
quarterly) and holders of Preferred Securities will be required to accrue
interest income for United States federal income tax purposes. See
"Description of the Debentures--Option to Extend Interest Payment Period" and
"Certain Federal Income Tax Consequences--Original Issue Discount."
 
  At any time on or after December 2, 1999, Host Marriott may, at its option,
cause the rights of holders of the Preferred Securities to convert the
Preferred Securities into Host Marriott Common Stock to expire. Host Marriott
may exercise this option only if for 20 trading days within any period of
30 consecutive trading days, including the last trading day of such period,
the Current Market Price (as defined herein) of Host Marriott Common Stock
exceeds 120% of the conversion price of the Preferred Securities, subject to
adjustment in certain circumstances. In order to exercise its option to
terminate the conversion rights of the Preferred Securities, Host Marriott
must issue a press release announcing the date upon which conversion rights
will expire prior to the opening of business on the second trading day after
any period in which the condition in the preceding sentence has been met, but
in no event prior to December 2, 1999. The date on which such conversion
rights will expire (the "Conversion Expiration Date") shall be a date not less
than 30 and not more than 60 days following the date of the issuance of the
press release described above. See "Description of the Preferred Securities--
Conversion Rights--Expiration of Conversion Rights."
 
  Except as provided below, the Preferred Securities may not be redeemed by
the Issuer prior to December 2, 1999. The Preferred Securities are subject to
redemption, in whole or in part, on or after such date, at redemption prices
set forth herein, upon any permitted redemption by Host Marriott of
Debentures, in a principal amount not to exceed the amount of the proceeds
derived by Host Marriott or its subsidiaries from the issuance and sale of
common stock within two years preceding the date fixed for redemption. See
"Description of the Preferred Securities--Optional Redemption." In the event
that, at any time after the Conversion Expiration Date, less than 5% of the
Preferred Securities remains outstanding, such Preferred Securities shall be
redeemable at the option of the Issuer, in whole but not in part, at a
redemption price equal to the liquidation preference for such Preferred
Securities and all accrued and unpaid Distributions. See "Description of the
Preferred Securities--Optional Redemption." In addition, the Preferred
Securities are subject to mandatory redemption upon the repayment at maturity
or as a result of acceleration of the Debentures. See "Description of the
Preferred Securities-- Mandatory Redemption."
 
  Under certain circumstances following the occurrence of a Special Event (as
herein defined), the Preferred Securities are also subject to (i) exchange, at
the option of the Issuer in the manner described herein, for Debentures (see
"Description of the Preferred Securities--Special Event Exchange or
Redemption") and (ii) redemption, in whole or in part, on or after December 2,
1999, if such Special Event constitutes a Tax Event (as defined herein). At
any time, Host Marriott has the right to terminate the Issuer and cause the
Debentures to be distributed to the holders of the Preferred Securities in
liquidation of the Issuer. See "Description of the Preferred Securities--
Distribution of Debentures."
 
  The Debentures are subordinate and junior in right of payment to all Senior
Debt of Host Marriott. The terms of the Debentures place no limitation on the
amount of Senior Debt that may be incurred by Host Marriott or the amount of
indebtedness that may be incurred by its subsidiaries. On a pro forma basis as
of September 6, 1996, Host Marriott had indebtedness of $142 million
(excluding various guarantees of debt obligations of certain affiliates on
such date in an aggregate amount of $128 million), all of which comprised
Senior Debt of Host Marriott. Host Marriott has the right from time
 
                                       2
<PAGE>
 
to time on or after December 2, 1999 to redeem, in whole or in part, the
Debentures at the redemption prices set forth herein, provided that the
principal amount so redeemed may not exceed the amount of proceeds derived from
Host Marriott or its subsidiaries from the issuance and sale of common stock
within two years preceding the date fixed for redemption.
 
  In the event of the termination of the Issuer, after satisfaction of the
creditors of the Issuer as provided by applicable law, the holders of the
Preferred Securities will be entitled to receive a liquidation preference of
$50 per Preferred Security plus accumulated and unpaid Distributions thereon to
the date of payment, which may be in the form of a distribution of such amount
in Debentures, subject to certain exceptions. See "Description of the Preferred
Securities--Liquidation Distribution Upon Termination."
 
  Whenever Host Marriott issues shares of Host Marriott Common Stock upon
conversion of Debentures, Host Marriott will, subject to certain conditions,
issue, together with each share of Host Marriott Common Stock, such number
(which number may be a fraction) of Rights (as defined herein) as shall at that
time be issuable with a share of Common Stock pursuant to the Rights Agreement
(as defined herein).

                                  RISK FACTORS
 
  Prospective purchasers of the Offered Securities should carefully review the
information contained elsewhere or incorporated by reference in this Prospectus
and should particularly consider the following matters.
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE DEBENTURES
 
  The obligations of Host Marriott under the Guarantee issued by Host Marriott
for the benefit of the holders of Preferred Securities are unsecured and rank
subordinate and junior in right of payment to all other liabilities of Host
Marriott and pari passu with any guarantee now or hereafter entered into by
Host Marriott in respect of any preferred or preference stock of any affiliate
of Host Marriott. The obligations of Host Marriott under the Debentures are
subordinate and junior in right of payment to all present and future Senior
Debt of Host Marriott. On a pro forma basis as of September 6, 1996 Host
Marriott had indebtedness of $142 million (excluding various guarantees of debt
obligations of certain affiliates on such date in an aggregate amount of $128
million), all of which comprised Senior Debt of Host Marriott. The ability of
the Issuer to pay amounts due on the Preferred Securities is solely dependent
upon Host Marriott making payments on the Debentures as and when required.
Neither the Indenture, the Guarantee nor the Trust Agreement places any
limitation on the amount of secured or unsecured debt, including Senior Debt,
that may be incurred by Host Marriott and its subsidiaries. See "Description of
the Guarantee--Status of the Guarantee" and "Description of the Debentures--
Subordination."
 
STRUCTURAL SUBORDINATION
 
  The Debentures are obligations of Host Marriott exclusively. Since
substantially all of Host Marriott's operations are conducted through
subsidiaries, substantially all of Host Marriott's cash flow and, consequently,
its ability to service debt, including the Debentures, is dependent upon the
earnings of its subsidiaries and the transfer of funds by those subsidiaries to
Host Marriott in the form of dividends or other transfers, supplemented with
borrowings. The ability of these subsidiaries to pay dividends to Host Marriott
in the future are subject to restrictions contained in indentures and other
financing agreements by which such subsidiaries are bound. See "--Limitations
on Host Marriott from Debt Financing."
 
  In addition, creditors of Host Marriott's subsidiaries are entitled to a
claim on the assets of such subsidiaries prior to any claims by Host Marriott.
Consequently, in the event of a liquidation or reorganization of any
subsidiary, creditors of such subsidiary are likely to be paid in full before
any distribution is made to Host Marriott, except to the extent that Host
Marriott itself is recognized as a creditor of such subsidiary, in which case
the claims of Host Marriott would still be subordinate to any security interest
in the assets of such subsidiary and any indebtedness of such subsidiary senior
to that held by Host Marriott. On a pro forma basis as of September 6, 1996,
the aggregate indebtedness (excluding accounts payable and accrued expenses,
deferred income taxes and other liabilities) of the consolidated subsidiaries
of Host Marriott was approximately $2.7 billion. See "Description of the
Preferred Securities--Distributions" and "Description of the Debentures--Option
to Extend Interest Payment Period."
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES
 
  Host Marriott has the right under the Indenture to defer the payment of
interest on the Debentures at any time or from time to time for a period not
exceeding 20 consecutive quarters with respect to each Extension Period,
provided that no Extension Period may extend beyond the stated maturity of the
Debentures. Upon the termination of any Extension Period and the payment of all
amounts then due, Host Marriott may select a new Extension Period and terminate
the payments of all amounts then due, subject to the requirements described
herein. As a consequence of any such deferral, quarterly
 
                                       4
<PAGE>
 
Distributions on the Preferred Securities by the Issuer will be deferred (and
the amount of Distributions to which holders of the Preferred Securities are
entitled will accumulate additional Distributions) during any such Extension
Period.
 
  Should an Extension Period occur, a holder of Preferred Securities will
continue to accrue income (in the form of original issue discount) in respect
of its pro rata share of the deferred interest allocable to the Debentures held
by the Issuer for United States Federal income tax purposes. As a result, a
holder of Preferred Securities will include such income in gross income for
United States Federal income tax purposes in advance of the receipt of cash,
and will not receive the cash related to such income from the Issuer if the
holder disposes of the Preferred Securities prior to the record date for the
payment of Distributions. See "Certain Federal Income Tax Consequences--
Original Issue Discount." Moreover, if a holder of Preferred Securities
converts its Preferred Securities into Host Marriott Common Stock during an
Extension Period, the holder will not receive any cash related to the deferred
distribution. Additionally, during the pendancy of any Extension Period, Host
Marriott will not be permitted, subject to certain exceptions set forth herein,
to declare or pay any cash distribution with respect to Host Marriott capital
stock or debt securities (including guarantees of indebtedness for money
borrowed) that rank pari passu with or junior to the Debentures. See
"Description of the Preferred Securities--Distributions."
 
  Host Marriott has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the
Debentures. However, should Host Marriott elect to exercise such right in the
future, the market price of the Preferred Securities is likely to be affected.
A holder that disposes of its Preferred Securities during an Extension Period,
therefore, might not receive the same return on its investment as a holder that
continues to hold its Preferred Securities. In addition, as a result of the
existence of Host Marriott's right to defer interest payments, the market price
of the Preferred Securities (which represent preferred undivided beneficial
interests in the Debentures) may be more volatile than the market prices of
other securities on which original issue discount accrues that are not subject
to such deferrals.
 
EXPIRATION OF CONVERSION RIGHTS
 
  On and after December 2, 1999, Host Marriott may, subject to certain
conditions, at its option, cause the conversion rights of holders of the
Preferred Securities to expire, provided that the Current Market Price of Host
Marriott Common Stock exceeds 120% of the conversion price of the Preferred
Securities for a specified period. See "Description of the Preferred
Securities--Conversion Rights--Expiration of Conversion Rights."
 
SPECIAL EVENT EXCHANGE OR REDEMPTION
 
  Upon certain circumstances following the occurrence and continuation of a
Special Event (as defined herein), the Preferred Securities are also subject to
(i) exchange in whole or, in the case of a Tax Event (as defined herein), in
whole or in part, in the manner described herein, for the Debentures or (ii)
redemption, in whole or in part, on or after December 2, 1999 in the case of a
Tax Event. See "Description of the Preferred Securities--Special Event Exchange
or Redemption."
 
  There can be no assurance as to the market prices for Preferred Securities or
Debentures that may be distributed in exchange for Preferred Securities if a
liquidation of the Issuer occurs or if the Preferred Securities are exchanged
for Debentures in connection with a Special Event. Accordingly, the Preferred
Securities that an investor may purchase, whether pursuant to the offer made
hereby or in the secondary market, or the Debentures that a holder of Preferred
Securities may receive on liquidation of the Issuer, may trade at a discount to
the price that the investor paid to purchase the Preferred Securities offered
hereby. Because holders of Preferred Securities may receive Debentures
 
                                       5
<PAGE>
 
on termination of the Issuer or if the Preferred Securities are exchanged for
Debentures in connection with a Special Event, prospective purchasers of
Preferred Securities are also making an investment decision with regard to the
Debentures and should carefully review all the information regarding the
Debentures contained herein. See "Description of the Preferred Securities--
Special Event Exchange or Redemption" and "Description of the Debentures--
General."
 
RIGHTS UNDER THE GUARANTEE
 
  The Guarantee guarantees to the holders of the Preferred Securities the
following payments, to the extent not paid by the Issuer: (i) any accumulated
and unpaid Distributions required to be paid on the Preferred Securities, to
the extent that the Issuer has funds on hand available therefor at such time,
(ii) the redemption price with respect to any Preferred Securities called for
redemption, to the extent that the Issuer has funds on hand available therefor
at such time, and (iii) upon a voluntary or involuntary dissolution, winding-up
or liquidation of the Issuer (unless the Debentures are distributed to holders
of the Preferred Securities), the lesser of (a) the aggregate of the
liquidation preference and all accrued and unpaid Distributions to the date of
payment to the extent that the Issuer has funds on hand available therefor at
such time and (b) the amount of assets of the Issuer remaining available for
distribution to holders of the Preferred Securities in liquidation of the
Issuer.
 
  As part of the Guarantee, Host Marriott agreed that it will honor all
obligations described therein relating to the conversion or exchange of the
Preferred Securities into or for Host Marriott Common Stock or Debentures.
 
  The holders of not less than a majority in aggregate liquidation amount of
the Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Guarantee or to direct the exercise of any trust power conferred
upon the Guarantee Trustee under the Guarantee. Any holder of Preferred
Securities may institute a proceeding directly against Host Marriott to enforce
its rights under the Guarantee without first instituting a proceeding against
the Issuer, the Guarantee Trustee or any other person or entity. If Host
Marriott were to default on its obligation to pay amounts payable under the
Debentures, the Issuer would lack funds for the payment of Distributions or
amounts payable on redemption of the Preferred Securities or otherwise, and, in
such event, holders of the Preferred Securities would not be able to rely upon
the Guarantee for payment of such amounts. Instead, in the event a Debenture
Event of Default shall have occurred and be continuing, a holder of Preferred
Securities would be required to rely on its enforcement by the Property Trustee
of its rights as registered holder of the Debenture against Host Marriott
pursuant to the terms of the Debenture. If, however, such event is attributable
to the failure of Host Marriott to pay interest on or principal of the
Debentures on the payment date on which such payment is due and payable, then a
holder of Preferred Securities may directly institute a proceeding against Host
Marriott for enforcement of payment to such holder of the interest on or
principal of such Debentures having a principal amount equal to the aggregate
liquidation preference of the Preferred Securities of such holder (a "Direct
Action"). In connection with such Direct Action, Host Marriott will be
subrogated to the rights of such holder of Preferred Securities under the Trust
Agreement to the extent of any payment made by Host Marriott to such holder of
Preferred Securities in such Direct Action. Except as set forth herein, holders
of Preferred Securities will not be able to exercise directly any other remedy
available to the holders of Debentures or assert directly any other rights in
respect of the Debentures. See "Description of the Preferred Securities--
Enforcement of Certain Rights by Holders of Preferred Securities," "Description
of the Guarantee" and "Description of the Debentures--Debenture Events of
Default." The Trust Agreement provides that each holder of Preferred Securities
by acceptance thereof agrees to the provisions of the Guarantee and the
Indenture.
 
                                       6
<PAGE>
 
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
  If a Declaration Event of Default (as defined herein) occurs and is
continuing, then the holders of Preferred Securities would rely on the
enforcement by the Property Trustee of its rights as the holder of the
Debentures against Host Marriott. In addition, the holders of a majority in
aggregate liquidation amount of the Preferred Securities have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Property Trustee or to direct the exercise of any trust or
power conferred upon the Property Trustee under the Trust Agreement, including
the right to direct the Property Trustee to exercise the remedies available to
it as a holder of the Debentures. If the Property Trustee fails to enforce its
rights as holder of the Debentures after a request therefor by a holder of
Preferred Securities, such holder may proceed to enforce such rights directly
against Host Marriott. Notwithstanding the following, if a Declaration Event of
Default occurs that results from the failure of Host Marriott to pay principal
of or interest on the Debentures when due (or in the case of a redemption, on
the redemption date), during the continuance of such an event of default a
holder of Preferred Securities may institute a legal proceeding directly
against Host Marriott to obtain payment to such holder (a "Direct Action") of
such principal or interest on Debentures having a principal amount equal to the
aggregate liquidation amount of the Preferred Securities owned of record by
such holder. See "Description of the Preferred Securities--Declaration Events
of Default; Notice" and "--Voting Rights; Amendment of the Trust Agreement."
 
LIMITED VOTING RIGHTS
 
  Holders of Preferred Securities generally have limited voting rights
primarily in connection with directing the activities of the Property Trustee
as the holder of the Debentures. Holders of Preferred Securities are not
entitled to vote to appoint, remove or replace the Issuer Trustees (as
defined), which voting rights are vested exclusively in the holder of the
Common Securities. The Issuer Trustees and Host Marriott may amend the Trust
Agreement without the consent of holders of Preferred Securities to ensure that
the Issuer will be classified for United States federal income tax purposes as
a grantor trust even if such action adversely affects the interests of such
holders. See "Description of the Preferred Securities--Voting Rights; Amendment
of the Trust Agreement."
 
PROPOSED TAX LEGISLATION
 
  As a part of President Clinton's Fiscal 1997 Budget Proposal, the Treasury
Department proposed legislation (the "Proposed Legislation") that, among other
things, would have treated as equity for United States federal income tax
purposes certain debt instruments with a maximum term of more than 20 years
that are not shown as indebtedness on the consolidated balance sheet of the
Issuer. The proposed legislation was to be effective for debt instruments
issued on or after December 7, 1995. Although this legislation was not enacted
as part of the Fiscal 1997 Budget, there can be no assurance that a similar
proposal would not be enacted in the future, that such future legislation would
not have a retroactive effective date and that such future legislation would
not prevent Host Marriott from deducting interest on the Debentures. This would
constitute a Tax Event and would permit the Issuer to exchange the Preferred
Securities, in whole or in part, for the Debentures or redeem, in whole or in
part, the Preferred Securities and corresponding Debentures.
 
POTENTIAL REDUCTION OF PAYMENTS TO NON-UNITED STATES HOLDERS FOR UNITED STATES
TAX WITHHOLDING REQUIREMENTS
 
  In the event that any United States taxes, duties or other governmental
charges are required to be deducted or withheld from any payments by Host
Marriott to holders of Preferred Securities that are not United States persons
(as defined herein), neither Host Marriott nor the Issuer would be required to
pay any additional amounts to such holders and, therefore, any such taxes,
duties or
 
                                       7
<PAGE>
 
charges would reduce the amounts received by such holders. See "Certain Federal
Income Tax Consequences--Certain United States Tax Consequences to Non-United
States Holders."
 
ABSENCE OF PUBLIC MARKET FOR THE PREFERRED SECURITIES AND RESTRICTIONS ON
RESALE
 
  Although the Preferred Securities are approved for trading in the PORTAL
market, there can be no assurance that any market for the Preferred Securities
will develop or, if one does develop, that it will be maintained. If an active
market for the Preferred Securities fails to develop or be sustained, the
trading price of the Preferred Securities could be adversely affected. The
Preferred Securities could trade at prices that may be higher or lower than the
offering price hereunder depending on many factors, including prevailing
interest rates, the price of the Common Stock, the Company's operating results,
any election by the Company to extend interest payment periods and the market
for similar securities. However, there can be no assurance as to the liquidity
of any trading market for the Preferred Securities or that an active public
market for the Preferred Securities will develop.
 
TRADING PRICE OF PREFERRED SECURITIES
 
  The Preferred Securities may trade at a price that does not fully reflect the
value of accrued but unpaid interest with respect to the underlying Debentures.
A holder disposing of Preferred Securities between record dates for payments of
distributions thereon will be required for United States Federal income tax
purposes to include accrued but unpaid interest on the Debentures through the
date of disposition in income as ordinary income (i.e., original issue
discount), and to add such amount to the adjusted tax basis in the holder's
Preferred Securities. To the extent the selling price is less than the holder's
adjusted tax basis (which will include, in the form of original issue discount,
all accrued but unpaid interest), a holder will recognize a capital loss.
Subject to certain limited exceptions, capital losses cannot be applied to
offset ordinary income for United States Federal income tax purposes. See
"Certain Federal Income Tax Consequences--Sales of Preferred Securities."
 
SUBSTANTIAL LEVERAGE AND LIMITED FINANCIAL FLEXIBILITY
 
  Host Marriott and its subsidiaries have substantial indebtedness. As of
September 6, 1996, on a pro forma basis, Host Marriott and its subsidiaries had
consolidated debt of $2.7 billion, representing 62% of its total
capitalization. Host Marriott's business is capital intensive, and Host
Marriott will have significant capital requirements in the future. Host
Marriott's leverage could affect its ability to obtain financing in the future
or to undertake refinancings on terms and subject to conditions deemed
acceptable by Host Marriott.
 
  In the event that Host Marriott's cash flow and working capital are not
sufficient to fund its expenditures or to service its indebtedness, Host
Marriott would be required to raise additional funds through the sale of
additional equity securities, the refinancing of all or part of its
indebtedness, the incurrence of additional permitted indebtedness (including
the Debentures), or the sale of assets. There can be no assurance that any of
these sources of funds would be available in amounts sufficient for Host
Marriott to meet its obligations. Moreover, even if Host Marriott were able to
meet its obligations, its leveraged capital structure could significantly limit
its ability to finance its acquisition program and other capital expenditures,
to compete effectively or to operate successfully under adverse economic
conditions.
 
LIMITATIONS ON HOST MARRIOTT FROM DEBT FINANCING
 
  The indentures relating to senior notes issued by certain of Host Marriott's
subsidiaries contain financial and operating covenants, including, but not
limited to, restrictions on the ability of such
 
                                       8
<PAGE>
 
subsidiaries to incur additional indebtedness and issue preferred stock, pay
dividends or make other distributions to Host Marriott, create liens, sell
assets, enter into certain transactions with affiliates, and enter into certain
mergers and consolidations. In addition, the $225 million revolving line of
credit with Marriott International (the "MI Line of Credit") imposes certain
restrictions on the ability of Host Marriott and certain of its subsidiaries to
incur additional debt, create liens or mortgages on their properties (other
than various types of liens arising in the ordinary course of business), extend
new guarantees (other than replacement guarantees), pay dividends and
repurchase their common stock. The above restrictions may limit Host Marriott's
ability to secure additional financing, and may prevent Host Marriott from
engaging in transactions that might otherwise be beneficial to Host Marriott
and to holders of Host Marriott Common Stock.
 
RISKS OF ACQUISITION STRATEGY
 
  Host Marriott intends to continue pursuing a strategy of growth through the
opportunistic acquisition of full-service urban, convention and resort hotels
primarily in the United States. There can be no assurance that Host Marriott
will find suitable properties for acquisition. Host Marriott incurs certain
costs in connection with the acquisition of new properties and may be required
to provide significant capital expenditures for conversions and upgrades when
acquiring a property operating as other than a Marriott-brand property. There
can be no assurance that any of the properties Host Marriott may acquire will
be profitable following such acquisition. The acquisition of a property that is
not profitable, or the acquisition of a property that results in significant
unanticipated conversion costs, could adversely affect Host Marriott's
profitability. Host Marriott expects to finance new acquisitions from a
combination of the proceeds from the Original Offering and, to the extent
available, operating cash flow, indebtedness and proceeds from the sale of
limited-service properties. Depending on the number, size and timing of such
transactions, Host Marriott may in the future require additional financing in
order to continue to make acquisitions. There is no assurance that such
additional financing, if any, will be available to Host Marriott on acceptable
terms.
 
COMPETITION AND RISKS OF THE LODGING INDUSTRY
 
  Host Marriott's hotels generally operate in areas that contain numerous other
competitors. There can be no assurance that demographic, geographic or other
changes in markets will not adversely affect the convenience or desirability of
the location of Host Marriott's hotels. Furthermore, there can be no assurance
that, in the markets in which Host Marriott's hotels operate, competing hotels
will not pose greater competition for guests than presently exists, or that new
hotels will not enter such markets.
 
  During the 1980s, construction of lodging facilities in the United States
resulted in an excess supply of available rooms. This over-supply had an
adverse effect on occupancy levels and room rates in the industry. Although the
current outlook for the industry has improved, there can be no assurance that
in the future the lodging industry, including Host Marriott and its hotels,
will not be adversely affected by (i) national and regional economic
conditions, (ii) changes in travel patterns, (iii) seasonality of the hotel
business, (iv) taxes and government regulations which influence or determine
wages, prices, interest rates, construction procedures and costs, and (v) the
availability of credit. Hotel investments are relatively illiquid. Such
illiquidity will tend to limit the ability of Host Marriott to respond to
changes in economic or other conditions.
 
POTENTIAL CONFLICTS WITH MARRIOTT INTERNATIONAL
 
  The interests of Host Marriott and Marriott International may conflict due to
the ongoing relationships between the companies. In addition, Host Marriott and
Marriott International share two common directors--J.W. Marriott, Jr. serves as
Chairman of the Board of Directors and President of
 
                                       9
<PAGE>
 
Marriott International and also serves as a director of Host Marriott, and
Richard E. Marriott serves as Chairman of the Board of Directors of Host
Marriott and also serves as a director of Marriott International. Messrs. J.W.
Marriott, Jr. and Richard E. Marriott, as well as certain other officers and
directors of Marriott International and Host Marriott, also own shares (and/or
options or other rights to acquire shares) in both companies. With respect to
the various contractual arrangements between the two companies, the potential
exists for disagreement as to the quality of services provided by Marriott
International and as to contract compliance. Any such disagreements between
Host Marriott and Marriott International could adversely affect the performance
of one or more of Host Marriott's hotels. Additionally, the possible desire of
Host Marriott, from time to time, to finance, refinance or effect a sale of any
of the properties managed by Marriott International may, depending upon the
structure of such transactions, result in a need to modify the management
agreement with Marriott International with respect to such property. Any such
modification proposed by Host Marriott may not be acceptable to Marriott
International, and the lack of consent from Marriott International could
adversely affect Host Marriott's ability to consummate such financing or sale.
In addition, certain situations could arise where actions taken by Marriott
International in its capacity as manager of competing lodging properties would
not necessarily be in the best interests of Host Marriott. Any such actions by
Marriott International could adversely impact one or more of Host Marriott's
hotels. Nevertheless, Host Marriott believes that there is sufficient mutuality
of interest between Host Marriott and Marriott International to result in a
mutually productive relationship. Moreover, appropriate policies and procedures
are followed by the Board of Directors of each of the companies to limit the
involvement of Messrs. J.W. Marriott, Jr. and Richard E. Marriott (and, if
appropriate, other officers and directors of such companies) in conflict
situations, including requiring them to abstain from voting as directors of
either Host Marriott or Marriott International (or as directors of any of their
subsidiaries) on certain matters which present a conflict between the
companies.
 
RISKS INVOLVED IN INVESTMENTS THROUGH PARTNERSHIPS OR JOINT VENTURES
 
  Historically, Host Marriott has served as a general or limited partner in
hotel partnerships, which typically owned a number of hotel properties and
involved numerous limited partners. More recently, Host Marriott's joint
venture arrangements have been focused on one or a small number of properties,
and have involved only a few partners, which could include the manager or
former owners of such hotels. In the future, Host Marriott intends selectively
to use joint venture arrangements to acquire properties and may consider
acquiring full or controlling interests in partnerships in which it currently
holds general or limited partner interests. Joint venturers may have certain
rights over the operation of the joint venture assets. Therefore, such
investments may, under certain circumstances, involve risks such as the
possibility that the co-venturer in an investment might become bankrupt, or
have economic or business interests or goals that are inconsistent with the
business interests or goals of Host Marriott, or be in a position to take
action contrary to the instructions or the requests of Host Marriott or
contrary to Host Marriott's policies or objectives. Consequently, actions by a
co-venturer might result in subjecting hotel properties owned by the joint
venture to additional risk. Although Host Marriott will seek to maintain
sufficient control of any joint venture to permit Host Marriott's objectives to
be achieved, it may be unable to take action without the approval of its joint
venture partners or its joint venture partners could take actions binding on
the joint venture without Host Marriott's consent. Additionally, should a joint
venture partner become bankrupt, Host Marriott could, in certain circumstances,
become liable for such partner's share of joint venture liabilities.
 
POTENTIAL ANTITAKEOVER EFFECT OF PROVISIONS IN HOST MARRIOTT'S CERTIFICATE OF
INCORPORATION AND BYLAWS
 
  Host Marriott's Restated Certificate of Incorporation and Bylaws each contain
provisions that will make difficult an acquisition of control of Host Marriott
by means of a tender offer, open market
 
                                       10
<PAGE>
 
purchases, proxy fight, or otherwise, that is not approved by the Board of
Directors. Provisions that may have an antitakeover effect include (i) a
staggered board of directors with three separate classes, (ii) a super-majority
vote requirement for removal or filling of vacancies on the Board of Directors
and for amendment to Host Marriott's Restated Certificate of Incorporation (the
"Company Certificate") and Bylaws, (iii) a prohibition on shareholder action by
written consent and (iv) super-majority voting requirements for approval of
mergers and other business combinations involving Host Marriott and interested
shareholders. In addition, Host Marriott is subject to Section 203 of the
Delaware General Corporation Law requiring super-majority approval for certain
business combinations. Host Marriott has also adopted a shareholder rights plan
which may discourage or delay a change in control of Host Marriott. Certain
indebtedness issued by subsidiaries of Host Marriott also have change of
control provisions that would require such indebtedness to be repurchased in
the event of a change of control which also may have the effect of discouraging
or delaying a change in control of Host Marriott. Finally, Host Marriott has
granted Marriott International, for a period expiring in October 2003, the
right to purchase up to 20% of each class of the then outstanding voting stock
of Host Marriott at the fair market value thereof upon the occurrence of
certain specified events, generally involving changes in control of Host
Marriott (the "Marriott International Purchase Right"). The Marriott
International Purchase Right may have certain antitakeover effects with respect
to Host Marriott. Any person considering acquiring a substantial or controlling
block of Common Stock would face the possibility that its ability to exercise
control would be impaired by Marriott International's 20% ownership resulting
from exercise of the Marriott International Purchase Right. It is also possible
that the exercise price of the Marriott International Purchase Right would be
lower than the price at which a potential acquirer might be willing to purchase
a 20% block of shares of Common Stock because the purchase price for the
Marriott International Purchase Right is based on the average trading price
during a 30-day period which may be prior to the announcement of the takeover
event. This potential price difference may have a further antitakeover effect
of discouraging potential acquirers of Host Marriott. See "Purposes and
Antitakeover Effects of Certain Provisions of the Company Certificate and
Bylaws and the Marriott International Purchase Right" and "Description of Host
Marriott Capital Stock--Rights and Junior Preferred Stock."
 
HISTORY OF LOSSES
 
  Host Marriott has sustained losses from continuing operations of $7 million
and $62 million for the First Three Quarters 1996 and fiscal year 1995,
respectively. Host Marriott's losses have resulted principally from
depreciation and write downs of the carrying values of certain assets to their
estimated sales values. There can be no assurance that Host Marriott will not
continue to experience losses from operations in the future.

Host Marriott Corporation and its subsidiaries and their combined operations.

January 1996 Hospitality Directions Quarterly Research Journal published by
Coopers & Lybrand LLP.
 
                                  THE COMPANY
 
  The Company is one of the largest owners of hotels in the world with 81
upscale and luxury full-service lodging properties as of January 15, 1997,
primarily located in the United States. These properties generally are
operated under the Marriott brand and are managed by Marriott International,
Inc. ("Marriott International"), formerly a wholly owned subsidiary of the
Company. Three of the Company's properties are operated under the Ritz-Carlton
brand in which Marriott International acquired a 49% interest in April 1995.
The Marriott and Ritz-Carlton brand names are among the most respected and
widely recognized brand names in the lodging industry. The Company's primary
focus is the acquisition of full-service lodging properties. Since 1994, the
Company has added 52 full-service hotels with 24,298 rooms for an aggregate
purchase price of almost $2.5 billion. Based on data provided by Smith Travel
Research, the Company believes that its full-service hotels consistently
outperform the industry's average occupancy rate by a significant margin and
averaged 78.6% occupancy for the First Three Quarters 1996 (as defined herein)
compared to 70.1% average occupancy for the upscale full-service segment of
the lodging industry (the segment which is most representative of the majority
of the Company's full-service hotels).
 
  The lodging industry as a whole, and the upscale and luxury full-service
hotel segments in particular, are benefiting from an improved supply and
demand relationship in the United States. Management believes that demand
increases have resulted primarily from an improved economic environment and a
corresponding increase in business travel. In spite of increased demand for
rooms, the room supply growth rate in the full-service segment has diminished.
Management believes that this decrease in the supply growth rate in the full-
service segment is attributable to many factors including the limited
availability of attractive building sites for full-service hotels, the lack of
available financing for new full-service hotel construction and the
availability of existing full-service properties for sale at a discount to
their replacement value. The relatively high occupancy rates of the Company's
hotels along with increased demand for full-service hotel rooms have allowed
the managers of the Company's hotels to increase average daily room rates by
primarily replacing certain discounted group business with higher-rated group
and transient business and by selectively raising room rates. As a result, on
a comparable basis, room revenues per available room ("REVPAR") for full-
service properties increased approximately 12% for the First Three Quarters
1996 over the comparable period for the prior year. Furthermore, because
lodging property operations have a high fixed cost component, increases in
REVPAR generally yield greater percentage increases in the Company's
consolidated Earnings Before Interest Expense, Taxes, Depreciation,
Amortization and other non-cash items (principally non-cash writedowns of
lodging properties and equity in earnings of an affiliate, net of
distributions received). ("EBITDA"). Accordingly, the approximately 12%
increase in REVPAR resulted in an approximately 18% increase in comparable
full-service EBITDA for the First Three Quarters 1996. The Company expects
this supply/demand imbalance, particularly in the upscale and luxury full-
service segments, to continue, which should result in improved REVPAR and
EBITDA at its hotel properties in the near term.
 
  BUSINESS STRATEGY. The Company's business strategy is to continue to focus
on opportunistic acquisitions of full-service urban, convention and resort
hotels primarily in the United States. The Company believes that the upscale
and luxury full-service segments of the market offer numerous opportunities to
acquire assets at attractive multiples of cash flow and at substantial
discounts to
 
                                      12
<PAGE>
 
replacement value, including underperforming hotels which can be improved by
conversion to the Marriott or Ritz-Carlton brands.
 
  Many desirable hotel properties are currently held by inadvertent owners
such as banks, insurance companies and other financial institutions, which are
motivated and willing sellers. The Company has acquired a number of properties
from these inadvertent owners at significant discounts to replacement cost,
including luxury hotels operating under the Ritz-Carlton brand. In the
Company's experience to date, these sellers have been primarily United States
financial organizations. The Company believes that numerous international
financial institutions are also inadvertent owners of lodging properties and
have only recently begun to dispose of such properties. The Company expects
that there will be increased opportunities to acquire lodging properties from
these international financial institutions.
 
  The Company holds minority interests and serves as general partner in
various partnerships that own, as of January 15, 1997, an aggregate of 251
additional properties, 31 of which are full-service properties, all managed by
Marriott International. Fourteen of the properties added by the Company to its
portfolio since 1994 were held by partnerships in which the Company held a
minority interest. Nine of those properties were added through investments
that increased the Company's partnership interest. The Company is actively
considering the acquisition of additional full-service properties currently
held by such partnerships and/or additional interests in such partnerships. On
January 14, 1997, the Company successfully completed the tender offer for
46.4% of the limited partnership units of the Marriott Hotel Properties
Limited Partnership ("MHP"), an affiliated partnership of the Company in which
the Company owned a 1% general partner interest and an approximate 1% limited
partner interest, by purchasing 464 limited partnership units for
approximately $37 million, or $80,000 per unit. MHP owns the 1,503-room
Marriott Orlando World Center and a 50.5% partnership interest in the 624-room
Marriott Harbor Beach Resort. As a result of this transaction, a wholly-owned
subsidiary of the Company became the largest limited partner in MHP which the
Company will consolidate in the first quarter of 1997.
 
  In addition to investments in partnerships in which it already held minority
interests, the Company has been successful in adding properties to its
portfolio through partnership arrangements with either the seller of the
property or the incoming manager (typically Marriott International or a
Marriott franchisee). The Company has the financial flexibility and, due to
its existing partnership investment portfolio, the administrative
infrastructure in place to accommodate such arrangements. The Company views
this ability as a competitive advantage and expects to enter into similar
arrangements in the future. The Company also believes that it has significant
opportunities to acquire additional Ritz-Carlton hotels through the Company's
relationship with Marriott International.
 
  While the Company's portfolio of lodging properties consists almost entirely
of upscale and luxury full-service hotels, management continually considers
the merits of diversifying into other compatible lodging-related real estate
assets that offer strong current economic benefits and growth prospects. The
Company is currently considering investments in senior living communities,
including portfolio transactions, which may offer attractive yields and stable
cash flows. The Company intends to finance its acquisition program through the
use of internally generated funds, additional equity and moderate levels of
indebtedness.

acquired six full-service hotels (1,964 rooms) for an aggregate purchase price
of $189 million and controlling interests in 17 additional properties (8,922
rooms) for an aggregate purchase price of approximately $1.1 billion
(including the assumption of $696 million of debt). In addition, the Company
purchased the mortgage loan secured by the 504-room New York Financial Center
Marriott for approximately $101 million. In 1996, the Company acquired or
gained control of the following properties:

  1997 TRANSACTION. On January 14, 1997, the Company successfully completed
the tender offer for 46.4% of the limited partnership units of MHP, an
affiliated partnership of the Company in which the Company owned a 1% general
partner interest and an approximate 1% limited partner interest, by purchasing
464 limited partnership units for approximately $37 million, or $80,000 per
unit. MHP owns the 1,503-room Marriott Orlando World Center and a 50.5%
partnership interest in the 624-room Marriott Harbor Beach Resort. As a result
of this transaction, a wholly-owned subsidiary of the Company became the
largest limited partner in MHP which the Company will consolidate in the first
quarter of 1997.
 
  The Company is also actively engaged in negotiations for a number of
additional full-service properties.
 
  SPECIAL DIVIDEND. Host Marriott previously operated food, beverage and
merchandise concessions at airports, on tollroads and at stadiums and arenas
and other tourist attractions (the "Operating Group Business"). On December
29, 1995, Host Marriott distributed the Operating Group Business to its
stockholders through a special dividend (the "Special Dividend") of all of the
outstanding shares of common stock of Host Marriott Services Corporation ("HM
Services").
 
                         HOST MARRIOTT FINANCIAL TRUST
 
  Host Marriott Financial Trust (the "Issuer") is a statutory business trust
created under Delaware law pursuant to (i) a trust agreement executed by Host
Marriott, as Depositor, and the Property Trustee, the Delaware Trustee and the
Administrative Trustees (each as defined herein) and (ii) the filing of a
certificate of trust with the Delaware Secretary of State on November 25,
1996. In connection with the Original Offering such trust agreement was
amended and restated in its entirety (as so amended and restated, the "Trust
Agreement"). The Issuer exists for the exclusive purposes of (i) issuing and
selling the Preferred Securities and Common Securities, (ii) using the
proceeds from
 
                                      14
<PAGE>
 
the sale of such Preferred Securities and Common Securities to acquire the
Debentures issued by Host Marriott and (iii) engaging in only those other
activities necessary or incidental thereto. Accordingly, the Debentures will
be the sole assets of the Issuer, and payments under the Debentures will be
the sole revenue of the Issuer. The Issuer has a term of 45 years, but may
terminate earlier as provided in the Trust Agreement.
 
  All of the Common Securities are owned by Host Marriott. The Common
Securities will rank pari passu, and payments will be made thereon pro rata,
with the Preferred Securities, except that upon the occurrence and continuance
of a Declaration Event of Default resulting from an Event of Default under the
Indenture, the rights of Host Marriott as holder of the Common Securities to
payment in respect of Distributions and payments upon liquidation, redemption
or otherwise are subordinated to the rights of the holders of the Preferred
Securities. See "Description of the Preferred Securities--Subordination of
Common Securities." Host Marriott has acquired Common Securities in an
aggregate liquidation amount equal to not less than 3% of the total capital of
the Issuer.
 
  The Issuer's business and affairs are conducted by its trustees, which were
appointed by Host Marriott as holder of the Common Securities. Pursuant to the
Trust Agreement, the number of trustees initially is five. Three of the
trustees (the "Administrative Trustees") are persons who are employees of
officers of, or affiliated with, Host Marriott. A fourth trustee is a
financial institution unaffiliated with Host Marriott that will serve as
property trustee (the "Property Trustee") under the Trust Agreement. IBJ
Schroder Bank & Trust Company is acting as the Property Trustee until removed
or replaced by the holder of the Common Securities. See "Description of the
Debentures." The fifth trustee is a financial institution or an affiliate
thereof which maintains a principal place of business or residence in the
State of Delaware (the "Delaware Trustee"). Delaware Trust Capital Management,
Inc. is acting as Delaware Trustee until removed or replaced by the holder of
the Common Securities. The Administrative Trustees, the Property Trustee and
the Delaware Trustee are referred to herein as the "Issuer Trustees." IBJ
Schroder Bank & Trust Company is also acting as indenture trustee under the
Guarantee (the "Guarantee Trustee"). See "Description of the Guarantee."
 
  The Property Trustee holds the title to the Debentures for the benefit of
the Issuer and holders of the Preferred Securities and the Common Securities
and has the power to exercise all rights, powers and privileges as holder of
the Debentures. In addition, the Property Trustee maintains exclusive control
of a segregated non-interest bearing bank account (the "Property Account") to
hold all payments made in respect of the Debentures for the benefit of the
Issuer and holders of the Preferred Securities and the Common Securities. The
Property Trustee will make payments of Distributions and payments on
liquidation, redemption and otherwise to the holders of the Preferred
Securities and the Common Securities out of funds from the Property Account.
The Guarantee Trustee holds the Guarantee for the benefit of the holders of
the Preferred Securities. Host Marriott, as the holder of all the Common
Securities, has the right to appoint, remove or replace any Issuer Trustee and
to increase or decrease the number of Issuer Trustees, provided that the
number of Issuer Trustees shall be at least three, a majority of which will be
Administrative Trustees. The duties and obligations of the Issuer Trustees are
governed by the Trust Agreement. The rights of the holders of the Preferred
Securities, including economic rights, right to information and voting rights,
are as set forth in the Trust Agreement and the Delaware Business Trust Act,
as amended (the "Trust Act").
 
  Host Marriott will pay all fees and expenses related to the Issuer and the
offering of the Preferred Securities and will pay, directly or indirectly, all
ongoing costs, expenses and liabilities of the Issuer. See "Description of the
Debentures--Expenses of Issuer." The principal executive office of the Issuer
is 10400 Fernwood Road, Bethesda, Maryland, 20817, Attention: Corporate
Secretary. The telephone number is (301) 380-9000.

                                USE OF PROCEEDS
 
  The Selling Holders will receive all of the proceeds from any sale of the
Offered Securities. Neither the Company, nor the Trust will receive any
proceeds from the sale of Offered Securities.
 
                             ACCOUNTING TREATMENT
 
  The financial statements of the Issuer are consolidated with the
consolidated financial statements of Host Marriott with the Preferred
Securities shown on such consolidated financial statements as "Company-
Obligated Mandatorily Redeemable Convertible Preferred Securities of a
Subsidiary Trust". The sole assets of the Issuer will be the 6 3/4%
Convertible Subordinated Debentures due 2026.

                    DESCRIPTION OF THE PREFERRED SECURITIES
 
  This summary of certain provisions of the Preferred Securities and the Trust
Agreement does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, all the provisions of the Trust Agreement (a
copy of which will be available for inspection at the corporate trust office
of the Property Trustee in New York, New York) and the Trust Act. The
Preferred Securities were issued in the Original Offering pursuant to the
terms of the Trust Agreement. Wherever particular defined terms of the Trust
Agreement are referred to herein, such defined terms are incorporated herein
or therein by reference.
 
GENERAL
 
  The Preferred Securities were issued in the Original Offering in fully
registered form without interest coupons. Bearer Preferred Securities were not
issued. The Trust Agreement authorizes the Issuer Trustees, on behalf of the
Issuer to issue the Preferred Securities and the Common Securities. The
Preferred Securities represent preferred undivided beneficial interests in the
assets of the Issuer and the Common Securities represent common undivided
beneficial interests in the assets of the Issuer. All of the Common Securities
are owned by Host Marriott. The Preferred Securities rank pari passu, and
payments are made thereon pro rata, with the Common Securities except as
described under "--Subordination of Common Securities." Legal title to the
Debentures is held by the Property Trustee in trust for the benefit of the
holders of the Preferred Securities and Common Securities. The Trust Agreement
does not permit the issuance by the Issuer of any securities other than the
Preferred Securities and the Common Securities or the incurrence of any
indebtedness by the Issuer. The payment of Distributions out of money held by
the Issuer, and payments upon redemption of the Preferred Securities or
liquidation of the Issuer, are guaranteed by Host Marriott to the extent
described under "Description of the Guarantee." The Guarantee is held by the
Guarantee Trustee for the benefit of the holders of the Preferred Securities.
The Guarantee does not cover payment of Distributions when the Issuer does not
have sufficient available funds to pay such Distributions. The remedy of a
holder of Preferred Securities in such an event is as described herein in "--
Voting Rights; Amendment of the Trust Agreement."
 
DISTRIBUTIONS
 
  Distributions on each Preferred Security are fixed at a rate per annum of 6
3/4% of the liquidation preference of $50 per Preferred Security.
Distributions accumulate from the date of original issuance and are payable
quarterly in arrears on March 1, June 1, September 1 and December 1 of each
year on the applicable record date, commencing March 1, 1997 when, as and if
available for payment by the Property Trustee, except as otherwise described
below. The amount of Distributions payable for any period is computed on the
basis of a 360-day year of twelve 30-day months. In the event that any date on
which Distributions are payable on the Preferred Securities is not a Business
Day (as defined below), then payment of the Distributions payable on such date
will be made on the next succeeding day that is a Business Day and without any
additional Distributions or other payment in respect of any such delay (each
date on which Distributions are payable in accordance with the foregoing, a
"Distribution Date"). A "Business Day" shall mean any day other than a
Saturday or a Sunday, or a day on which banking institutions in the City of
New York are authorized or required by law or executive order to remain closed
or a day on which the corporate trust office of the Property Trustee or the
Debenture Trustee is closed for business.
 
  So long as no Debenture Event of Default has occurred and is continuing,
Host Marriott has the right under the Indenture to defer the payment of
interest (including any Liquidated Damages) on the Debentures at any time or
from time to time for a period not exceeding 20 consecutive quarters with
respect to each deferral period (each an "Extension Period"), provided that no
Extension Period may extend beyond the stated maturity of the Debentures. As a
consequence of any such election,
 
                                      17
<PAGE>
 
quarterly Distributions on the Preferred Securities would be deferred by the
Issuer during any such Extension Period. Distributions to which holders of the
Preferred Securities are entitled would accumulate additional Distributions
thereon at the rate per annum set forth herein, compounded quarterly from the
relevant payment date for such Distributions. The term "Distributions" as used
herein includes any such additional Distributions. During any such Extension
Period, Host Marriott may not, and may not cause any of its subsidiaries to,
(i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire, or make a liquidation payment with respect to, any of Host Marriott's
capital stock, or (ii) make any payment of principal, interest or premium, if
any, on or repay, repurchase or redeem any debt securities (including
guarantees of indebtedness for money borrowed) of Host Marriott that rank pari
passu with or junior to the Debentures (other than (a) any dividend,
redemption, liquidation, interest, principal or guarantee payment by Host
Marriott where the payment is made by way of securities (including capital
stock) that rank pari passu with or junior to the securities on which such
dividend, redemption, interest, principal or guarantee payment is being made,
(b) redemptions or purchases of any Rights pursuant to Host Marriott's Rights
Agreement, or any successor to such Rights Agreement, and the declaration of a
dividend of such Rights or the issuance of preferred stock under such plans in
the future, (c) payments under the Guarantee, (d) purchases of Host Marriott
Common Stock related to the issuance of Host Marriott Common Stock under any
of Host Marriott's benefit plans for its directors, officers or employees, (e)
as a result of a reclassification of Host Marriott's capital stock or the
exchange or conversion of one series or class of Host Marriott's capital stock
for another series or class of Host Marriott's capital stock, and (f) the
purchase of fractional interests in shares of Host Marriott's capital stock
pursuant to the conversion or exchange provisions of such capital stock or the
security being converted or exchanged). Prior to the termination of any such
Extension Period, Host Marriott may further extend the interest payment
period, provided that no Extension Period may exceed 20 consecutive quarters
or extend beyond the stated maturity of the Debentures. Upon the termination
of any such Extension Period and the payment of all amounts then due on any
Interest Payment Date, Host Marriott may elect to begin a new Extension
Period. See "Description of the Debentures--Option to Extend Interest Payment
Period" and "Certain Federal Income Tax Consequences--Original Issue
Discount."
 
  Host Marriott has no current intention to exercise its right to defer
payments of interest by extending the interest payment period on the
Debentures.
 
  Distributions with respect to the Preferred Securities are made on the dates
payable to the extent that the Issuer has funds available for the payment of
such Distributions in the Property Account. The funds of the Issuer available
for distribution to holders of the Preferred Securities are limited to
payments under the Debentures in which the Issuer has invested the proceeds
from the issuance and sale of the Preferred Securities and the Common
Securities. See "Description of the Debentures." If Host Marriott does not
make interest payments on such Debentures, the Property Trustee would not have
funds available to pay Distributions on the Preferred Securities. The payment
of Distributions (if and to the extent the Issuer has funds on hand available
for the payment of such Distributions and cash sufficient to make such
payments) is guaranteed by Host Marriott on a limited basis as set forth
herein under "Description of the Guarantee."
 
  Distributions on the Preferred Securities are payable to the holders thereof
as they appear on the register of the Issuer on the relevant record dates,
which are the fifteenth day (whether or not a Business Day) next preceding the
relevant distribution date. As long as the Preferred Securities remain in
book-entry form, subject to any applicable laws and regulations and the
provisions of the Trust Agreement, each such payment will be made as described
under "--Form, Transfer, Exchange and Book-Entry Procedures."
 
 
                                      18

CONVERSION RIGHTS
 
 GENERAL
 
  The Preferred Securities are convertible at any time prior to the Conversion
Expiration Date (as defined herein), at the option of the holder thereof and in
the manner described below, into shares of Host Marriott Common Stock at an
initial conversion rate of 2.6876 shares of Host Marriott Common Stock for each
Preferred Security (equivalent to a purchase price of $18.604 per share of Host
Marriott Common Stock), subject to adjustment as described under "--Conversion
Price Adjustments" below. Whenever Host Marriott issues shares of Host Marriott
Common Stock upon conversion of Preferred Securities and Host Marriott has in
effect at such time a share purchase rights agreement under which holders of
Host Marriott Common Stock are issued rights entitling the holders under
certain circumstances to purchase an additional share or shares of Host
Marriott Common Stock, Host Marriott will issue, together with each such share
of Host Marriott Common Stock, an appropriate number of rights. For a
description of Host Marriott's existing shareholder rights agreement, see
"Description of Host Marriott Capital Stock--Rights and Junior Preferred
Stock."
 
  A holder of Preferred Securities wishing to exercise its conversion right
shall surrender such Preferred Securities, together with an irrevocable
conversion notice to the Property Trustee, as conversion agent or to such other
agent appointed for such purpose (the "Conversion Agent"), which shall, on
behalf of such holder, exchange the Preferred Securities for a portion of the
Debentures and immediately convert such Debentures into Host Marriott Common
Stock. So long as a book-entry system for the Preferred Securities is in
effect, however, the procedures for converting the Preferred Stock that are in
the form of Global Certificates into shares of Common Stock will be as
described under "--Form, Transfer, Exchange and Book-Entry Procedures." Host
Marriott's delivery upon conversion of the fixed number of shares of Host
Marriott Common Stock into which the Debentures are convertible (together with
the cash payment, if any, in lieu of any fractional share) shall be deemed to
satisfy Host Marriott's obligation to pay the principal amount at maturity of
the portion of the Debentures so converted and any unpaid interest accrued on
such Debentures at the time of such conversion. For a discussion of the
taxation of such an exchange to holders, including the possibility that holders
who exchange their Preferred Securities for Host Marriott Common Stock may be
subject to additional income tax to the extent accrued but unpaid interest on
the Debentures is converted into Host Marriott Common Stock, see "Certain
Federal Income Tax Consequences--Conversion of Preferred Securities into Host
Marriott Common Stock." Holders may obtain copies of the required form of the
conversion notice from the Conversion Agent.
 
  Accrued Distributions will not be paid on Preferred Securities that are
converted, provided however, that holders of Preferred Securities at the close
of business on a Distribution payment record date will be entitled to receive
the Distribution payable on such Preferred Securities on the corresponding
Distribution payment date notwithstanding the conversion of such Preferred
Securities on or subsequent to such Distribution record date but prior to such
Distribution payment date. Except as provided in the immediately preceding
sentence, the Issuer will make no payment or allowance for accumulated and
unpaid Distributions, whether or not in arrears, on converted Preferred
Securities. Host Marriott will make no payment or allowance for dividends on
the shares of Host Marriott Common Stock issued upon such conversion. Each
conversion will be deemed to have been effected immediately prior to the close
of business on the day on which proper notice was received by the Conversion
Agent.
 
  Shares of Host Marriott Common Stock issued upon conversion of Preferred
Securities are validly issued, fully paid and non-assessable. No fractional
shares of Host Marriott Common Stock will be issued as a result of conversion,
but in lieu thereof such fractional interest will be paid in cash.
 
 EXPIRATION OF CONVERSION RIGHTS
 
  On and after December 2, 1999 Host Marriott may, at its option, cause the
conversion rights of holders of the Preferred Securities to expire. Host
Marriott may exercise this option only if for 20
 
                                       19
<PAGE>
 
trading days within any period of 30 consecutive trading days, including the
last trading day of such period, the Current Market Price of Host Marriott
Common Stock exceeds 120% of the conversion price of the Preferred Securities,
subject to adjustment in certain circumstances. In order to exercise its option
to terminate the conversion rights of the Preferred Securities, Host Marriott
must issue a press release for publication on the Dow Jones News Service
announcing the Conversion Expiration Date prior to the opening of business on
the second trading day after any period in which the condition in the preceding
sentence has been met, but in no event prior to December 2, 1999. The press
release shall announce the Conversion Expiration Date and provide the current
conversion price and Current Market Price of Host Marriott Common Stock, in
each case as of the close of business on the trading day next preceding the
date of the press release. Conversion rights will terminate at the close of
business on the Conversion Expiration Date.
 
  Notice of the expiration of conversion rights will be given by Host Marriott
by first-class mail to the holders of the Preferred Securities not more than
four Business Days after Host Marriott issues the press release. The Conversion
Expiration Date will be a date selected by Host Marriott not less than 30 nor
more than 60 days after the date on which Host Marriott issues the press
release announcing its intention to terminate the conversion rights of the
Preferred Securities. In the event that Host Marriott does not exercise its
option to terminate the conversion rights of the Preferred Securities, the
Conversion Expiration Date with respect to the Preferred Securities will be two
Business Days preceding the date set for redemption of the Preferred
Securities.
 
  The term "Current Market Price" of Host Marriott Common Stock for any day
means the last reported sale price, regular way, on such day, or, if no sale
takes place on such day, the average of the reported closing bid and asked
prices on such day, regular way, in either case as reported on the NYSE
Composite Transactions Tape, or, if the Host Marriott Common Stock is not
listed or admitted to trading on the NYSE on such day, on the principal
national securities exchange on which the Host Marriott Common Stock is listed
or admitted to trading, if the Host Marriott Common Stock is listed on a
national securities exchange, or the Nasdaq National Market, or, if the Host
Marriott Common Stock is not quoted or admitted to trading on such quotation
system, on the principal quotation system on which the Host Marriott Common
Stock may be listed or admitted to trading or quoted, or, if not listed or
admitted to trading or quoted on any national securities exchange or quotation
system, the average of the closing bid and asked prices of the Host Marriott
Common Stock in the over-the-counter market on the day in question as reported
by the National Quotation Bureau Incorporated, or a similar generally accepted
reporting service, or, if not so available in such manner, as furnished by any
NYSE member firm selected from time to time by the Board of Directors of Host
Marriott for that purpose or, if not so available in such manner, as otherwise
determined in good faith by the Board of Directors of Host Marriott.
 
 CONVERSION PRICE ADJUSTMENTS
 
  GENERAL. The conversion price is subject to adjustment in certain events
including, without duplication: (i) the payment of dividends (and other
distributions) payable exclusively in Host Marriott Common Stock on Host
Marriott Common Stock; (ii) the issuance to all holders of Host Marriott Common
Stock of rights or warrants entitling holders of such rights or warrants (for a
period not exceeding 45 days) to subscribe for or purchase Host Marriott Common
Stock at less than the then Current Market Price; (iii) subdivisions and
combinations of Host Marriott Common Stock; (iv) the payment of dividends (and
other distributions) to all holders of Host Marriott Common Stock consisting of
evidences of indebtedness of Host Marriott, securities or capital stock, cash,
or assets (including securities, but excluding those rights or warrants
referred to above in clause (ii) and dividends and distributions paid
exclusively in cash); (v) the payment of dividends (and other distributions) on
Host Marriott Common Stock paid exclusively in cash, excluding (A) cash
dividends that do not exceed the per share amount of the immediately preceding
regular cash dividend (as adjusted to reflect any of the events referred to in
clauses (i) through (vi) of this sentence), and (B) cash dividends if the
annualized per share amount thereof does not exceed 12.5% of the last sale
price of Host Marriott Common
 
                                       20
<PAGE>
 
Stock, as reported on the NYSE Consolidated Transactions Tape, on the trading
day immediately preceding the date of declaration of such dividend (such
adjustment being limited to the amount in excess of 12.5% of such Current
Market Price); and (vi) payment in respect of a tender or exchange offer (other
than an odd-lot offer) by Host Marriott or any subsidiary of Host Marriott for
Host Marriott Common Stock in excess of 110% of the Current Market Price of
Host Marriott Common Stock on the trading day next succeeding the last date
tenders or exchanges may be made pursuant to such tender or exchange offer.
 
  If the distribution date for the Rights of Host Marriott provided in the
Rights Agreement, as presently constituted or under any similar plan (see
"Description of Host Marriott Capital Stock-- Rights and Junior Preferred
Stock"), occurs prior to the date a Preferred Security is converted, holders of
the Preferred Securities who convert such Preferred Securities after the
distribution date are not entitled to receive the Rights that would otherwise
be attached (but for the date of conversion) to the shares of Host Marriott
Common Stock received upon such conversion. However, adjustment of the
conversion price shall be made under clause (ii) of the preceding paragraph as
if the Rights were being distributed to the common stockholders of Host
Marriott immediately prior to such conversion. If such an adjustment is made
and the Rights are later redeemed, invalidated or terminated, then a
corresponding reversing adjustment shall be made to the conversion price, on an
equitable basis, to take account of such event.
 
  Host Marriott from time to time may reduce the conversion price of the
Debentures (and thus the conversion price of the Preferred Securities) by any
amount selected by Host Marriott for any period of at least 30 days, in which
case Host Marriott shall give at least 15 days' notice of such reduction. Host
Marriott may, at its option, make such reductions in the conversion price, in
addition to those set forth above, as the Board of Directors of Host Marriott
deems advisable to avoid or diminish any income tax to holders of Host Marriott
Common Stock resulting from any dividend or distribution of stock (or rights to
acquire stock) or from any event treated as such for income tax purposes. See
"Certain Federal Income Tax Consequences--Adjustment of Conversion Price."
 
  No adjustment of the conversion price will be made upon the issuance of any
shares of Host Marriott Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on securities
of Host Marriott and the investment of additional optional amounts in shares of
Host Marriott Common Stock under any such plan, or the issuance of any shares
of Host Marriott Common Stock or options or rights to purchase such shares
pursuant to any present or future employee benefit plan or program of Host
Marriott or pursuant to any option, warrant, right, or exercisable,
exchangeable or convertible security which does not constitute an issuance to
all holders of Host Marriott Common Stock of rights or warrants entitling
holders of such rights or warrants to subscribe for or purchase Host Marriott
Common Stock at less than the Current Market Price. There shall also be no
adjustment of the conversion price in case of the issuance of any Host Marriott
Common Stock (or securities convertible into or exchangeable for Host Marriott
Common Stock), except as specifically described above. If any action would
require adjustment of the conversion price pursuant to more than one of the
anti-dilution provisions, only one adjustment shall be made and such adjustment
shall be the amount of adjustment that has the highest absolute value to
holders of the Preferred Securities. No adjustment in the conversion price will
be required unless such adjustment would require an increase or decrease of at
least 1% of the conversion price, but any adjustment that would otherwise be
required to be made shall be carried forward and taken into account in any
subsequent adjustment.
 
  MERGER, CONSOLIDATION OR SALE OF ASSETS OF HOST MARRIOTT. In the event that
Host Marriott is a party to any transaction (including, without limitation, a
merger other than a merger that does not result in a reclassification,
conversion, exchange or cancellation of Host Marriott Common Stock),
consolidation, sale of all or substantially all of the assets of Host Marriott,
recapitalization or
 
                                       21
<PAGE>
 
reclassification of Host Marriott Common Stock (other than a change in par
value, or from par value to no par value, or from no par value to par value or
as a result of a subdivision or combination of Host Marriott Common Stock) or
any compulsory share exchange (each of the foregoing being referred to as a
"Transaction"), in each case, as a result of which shares of Host Marriott
Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (as defined below) (and subject to
funds being legally available for such purpose under applicable law at the time
of such conversion), securities, cash or other property, each Preferred
Security shall thereafter be convertible into the kind and, in the case of a
Transaction which does not involve a Fundamental Change (as defined below),
amount of securities, cash and other property receivable upon the consummation
of such Transaction by a holder of that number of shares of Host Marriott
Common Stock into which a Preferred Security was convertible immediately prior
to such Transaction, or (ii) in the case of a Transaction involving a Common
Stock Fundamental Change, common stock, each Preferred Security shall
thereafter be convertible (in the manner described herein) into common stock of
the kind received by holders of Host Marriott Common Stock (but in each case
after giving effect to any adjustment discussed below relating to a Fundamental
Change if such Transaction constitutes a Fundamental Change. The holders of
Preferred Securities will have no voting rights with respect to any Transaction
described in this section.
 
  If any Fundamental Change occurs, then the conversion price in effect will be
adjusted immediately after such Fundamental Change as described below. In
addition, in the event of a Common Stock Fundamental Change, each Preferred
Security shall be convertible solely into common stock of the kind received by
holders of Host Marriott Common Stock as a result of such Common Stock
Fundamental Change.
 
  The conversion price in the case of any Transaction involving a Fundamental
Change will be adjusted immediately after such Fundamental Change:
 
    (i) in the case of a Non-Stock Fundamental Change (as defined below), the
  conversion price of the Preferred Securities will thereupon become the
  lower of (A) the conversion price in effect immediately prior to such Non-
  Stock Fundamental Change, but after giving effect to any other prior
  adjustments effected pursuant to the preceding paragraphs, and (B) the
  result obtained by multiplying the greater of the Applicable Price (as
  defined below) or the then applicable Reference Market Price (as defined
  below) by a fraction, the numerator of which is $50 and the denominator of
  which is (x) the amount of the redemption price for Preferred Security if
  the redemption date were the date of such Non-Stock Fundamental Change (or,
  for the period commencing on the first date of original issuance of the
  Preferred Securities and through December 1, 1997, and the twelve-month
  periods commencing December 2, 1997 and December 2, 1998, the product of
  106.75, 106.075 and 105.400, respectively, multiplied by $50) plus (y) any
  then-accrued and unpaid distributions on one Preferred Security; and
 
    (ii) in the case of a Common Stock Fundamental Change, the conversion
  price of the Preferred Securities in effect immediately prior to such
  Common Stock Fundamental Change, but after giving effect to any other prior
  adjustments effected pursuant to the preceeding paragraphs, will thereupon
  be adjusted by multiplying such conversion price by a fraction of which the
  numerator will be the Purchaser Stock Price (as defined below) and the
  denominator will be the Applicable Price; provided, however, that in the
  event of a Common Stock Fundamental Change in which (A) 100% of the value
  of the consideration received by a holder of Host Marriott Common Stock is
  common stock of the successor, acquiror, or other third party (and cash, if
  any, is paid only with respect to any fractional interests in such common
  stock resulting from such Common Stock Fundamental Change) and (B) all Host
  Marriott Common Stock will have been exchanged for, converted into, or
  acquired for common stock (and cash with respect to fractional interests)
  of the successor, acquiror, or other third party, the conversion price of
  the Preferred Securities in
 
                                       22
<PAGE>
 
  effect immediately prior to such Common Stock Fundamental Change will
  thereupon be adjusted by multiplying such conversion price by a fraction of
  which the numerator will be one and the denominator will be the number of
  shares of common stock of the successor, acquiror, or other third party
  received by a holder of one share of Host Marriott Common Stock as a result
  of such Common Stock Fundamental Change.
 
  In the absence of the Fundamental Change provisions, in the case of a
Transaction each Preferred Security would become convertible into the
securities, cash, or property receivable by a holder of the number of shares of
Host Marriott Common Stock into which such Preferred Security was convertible
immediately prior to such Transaction. A failure to apply the Fundamental
Change conversion price adjustments described above could substantially lessen
or eliminate the value of the conversion privilege associated with the
Preferred Securities. For example, if Host Marriott were acquired in a cash
merger, each Preferred Security would become convertible solely into cash and
would no longer be convertible into securities whose value would vary depending
on the future prospects of Host Marriott and other factors.
 
  The foregoing conversion price adjustments are designed, in certain
circumstances, to reduce the conversion price that would be applicable in
"Fundamental Change" Transactions where all or substantially all the Host
Marriott Common Stock is converted into securities, cash, or property and not
more than 50% of the value received by the holders of Host Marriott Common
Stock consists of stock listed or admitted for listing subject to notice of
issuance on the NYSE or a national securities exchange or quoted on the Nasdaq
National Market (a Non-Stock Fundamental Change, as defined below). Such
reduction would result in an increase in the amount of the securities, cash, or
property into which each Preferred Security is convertible over that which
would have been obtained in the absence of such conversion price adjustments.
 
  In a Non-Stock Fundamental Change Transaction where the initial value
received per share of Host Marriott Common Stock (measured as described in the
definition of Applicable Price below) is lower than the then applicable
conversion price of a Preferred Security but greater than or equal to the
"Reference Market Price", the conversion price will be adjusted as described
above with the effect that each Preferred Security will be convertible into
securities, cash or property of the same type received by the holders of Host
Marriott Common Stock in the Transaction but in an amount per Preferred
Security that would at the time of the Transaction have had a value equal to
the then applicable redemption price per Preferred Security set forth below
under "--Optional Redemption" (or, for periods prior to the date on and after
which Host Marriott may cause the conversion rights of holders of Preferred
Securities to expire.
 
  In a Non-Stock Fundamental Change Transaction where the initial value
received per share of Host Marriott Common Stock (measured as described in the
definition of Applicable Price) is lower than both the conversion price of a
Preferred Security in effect prior to any adjustment described above and the
Reference Market Price, the conversion price will be adjusted as described
above but calculated as though such initial value had been the Reference Market
Price.
 
  In a Fundamental Change Transaction where all or substantially all the Host
Marriott Common Stock is converted into securities, cash, or property and more
than 50% of the value received by the holders of Host Marriott Common Stock
consists of listed or Nasdaq National Market traded common stock (a Common
Stock Fundamental Change, as defined below), the foregoing adjustments are
designed to provide in effect that (a) where Host Marriott Common Stock is
converted partly into such common stock and partly into other securities, cash,
or property, each Preferred Security will be convertible solely into a number
of shares of such common stock determined so that the initial value of such
shares (measured as described in the definition of "Purchaser Stock Price"
below) equals the value of the shares of Host Marriott Common Stock into which
such Preferred Security was convertible
 
                                       23
<PAGE>
 
immediately before the Transaction (measured as aforesaid) and (b) where Host
Marriott Common Stock is converted solely into such common stock, each
Preferred Security will be convertible into the same number of shares of such
common stock receivable by a holder of the number of shares of Host Marriott
Common Stock into which such Preferred Security was convertible immediately
before such Transaction.
 
  The term "Applicable Price" means (i) in the case of a Non-Stock Fundamental
Change in which the holders of the Host Marriott Common Stock receive only
cash, the amount of cash received by the holder of one share of Host Marriott
Common Stock and (ii) in the event of any other Non-Stock Fundamental Change or
any Common Stock Fundamental Change, the average of the Closing Prices (as
defined below) for the Host Marriott Common Stock during the ten trading days
prior to the record date for the determination of the holders of Host Marriott
Common Stock entitled to receive such securities, cash, or other property in
connection with such Non-Stock Fundamental Change or Common Stock Fundamental
Change or, if there is no such record date, the date upon which the holders of
the Host Marriott Common Stock shall have the right to receive such securities,
cash, or other property (such record date or distribution date being
hereinafter referred to as the "Entitlement Date"), in each case as adjusted in
good faith by Host Marriott to appropriately reflect any of the events referred
to in clauses (i) through (vi) of the first paragraph under "--Conversion Price
Adjustments--General."
 
  The term "Closing Price" means on any day the reported last sale price on
such day or in case no sale takes place on such day, the average of the
reported closing bid and asked prices in each case on the NYSE Consolidated
Transactions Tape or, if the stock is not listed or admitted to trading on the
NYSE, on the principal national securities exchange on which such stock is
listed or admitted to trading or, if not listed or admitted to trading on any
national securities exchange, the average of the closing bid and asked prices
as furnished by any NYSE member firm, selected by the Debenture Trustee for
that purpose.
 
  The term "Common Stock Fundamental Change" means any Fundamental Change in
which more than 50% of the value (as determined in good faith by the Board of
Directors of Host Marriott) of the consideration received by holders of Host
Marriott Common Stock consists of common stock that for each of the ten
consecutive trading days prior to the Entitlement Date has been admitted for
listing or admitted for listing subject to notice of issuance on a national
securities exchange or quoted on the Nasdaq National Market; provided, however,
that a Fundamental Change shall not be a Common Stock Fundamental Change unless
either (i) Host Marriott continues to exist after the occurrence of such
Fundamental Change and the outstanding Preferred Securities continue to exist
as outstanding Preferred Securities or (ii) not later than the occurrence of
such Fundamental Change, the outstanding Preferred Securities are converted
into or exchanged for shares of convertible preferred stock of an entity
succeeding to the business of Host Marriott or a subsidiary thereof, which
convertible preferred stock has powers, preferences, and relative,
participating, optional, or other rights, and qualifications, limitations, and
restrictions, substantially similar to those of the Preferred Securities.
 
  The term "Fundamental Change" means the occurrence of any Transaction or
event in connection with a plan pursuant to which all or substantially all of
the Host Marriott Common Stock shall be exchanged for, converted into, acquired
for, or constitute solely the right to receive securities, cash, or other
property (whether by means of an exchange offer, liquidation, tender offer,
consolidation, merger, combination, reclassification, recapitalization, or
otherwise), provided, that, in the case of a plan involving more than one such
Transaction or event, for purposes of adjustment of the conversion price, such
Fundamental Change shall be deemed to have occurred when substantially all of
the Host Marriott Common Stock shall be exchanged for, converted into, or
acquired for or constitute solely the right to receive securities, cash, or
other property, but the adjustment shall be based upon the consideration that a
holder of Host Marriott Common Stock received in such Transaction or event as a
result of which more than 50% of the Host Marriott Common Stock shall have been
exchanged for,
 
                                       24
<PAGE>
 
converted into, or acquired for or constitute solely the right to receive
securities, cash, or other property.
 
  The term "Non-Stock Fundamental Change" means any Fundamental Change other
than a Common Stock Fundamental Change.
 
  The term "Purchaser Stock Price" means, with respect to any Common Stock
Fundamental Change, the average of the Closing Prices for the common stock
received in such Common Stock Fundamental Change for the ten consecutive
trading days prior to and including the Entitlement Date, as adjusted in good
faith by Host Marriott to appropriately reflect any of the events referred to
in clauses (i) through (vi) of the first paragraph under "--Conversion Price
Adjustments--General."
 
  The term "Reference Market Price" shall initially mean $10.083 (which is an
amount equal to 66 2/3% of the reported last sales price for Host Marriott
Common Stock on the NYSE Corporate Tape on November 25, 1996) and in the event
of any adjustment of the conversion price other than as a result of a Non-Stock
Fundamental Change, the Reference Market Price shall also be adjusted so that
the ratio of the Reference Market Price to the conversion price after giving
effect to any such adjustment shall always be the same as the ratio of the
initial Reference Market Price to the initial conversion price of the Preferred
Securities.
 
SPECIAL EVENT EXCHANGE OR REDEMPTION
 
  At any time following the occurrence and the continuation of a Tax Event or
an Investment Company Event, the Issuer Trustees shall direct the Conversion
Agent to exchange all outstanding Preferred Securities for Debentures, provided
that, in the case of a Tax Event, Host Marriott shall have the right to (a)
direct that less than all, or none, of the Preferred Securities be so exchanged
if and for so long as Host Marriott shall have elected to pay any Additional
Sums (as defined below) such that the net amounts received by the holders of
Preferred Securities not so exchanged in respect of Distributions and other
distributions are not reduced as a result of such Tax Event, and shall not have
revoked any such election or failed to make such payments or (b) redeem the
Preferred Securities in the manner set forth below.
 
  If, a Tax Event shall occur or be continuing, Host Marriott 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 upon the later of (i) 90 days
following the occurrence of such Tax Event or (ii) December 2, 1999. Promptly
following such redemption, Preferred Securities and Common Securities with an
aggregate liquidation amount equal to the aggregate principal amount of the
Debentures so redeemed will be redeemed by the Issuer at the liquidation amount
thereof plus accrued and unpaid Distributions thereon to the redemption date on
a pro rata basis. The Common Securities will be redeemed on a pro rata basis
with the Preferred Securities, except that if a Declaration Event of Default
has occurred and is continuing, the Preferred Securities will have a priority
over the Common Securities with respect to the Redemption Price.
 
  A "Special Event" means a Tax Event or an Investment Company Event. A "Tax
Event" means the receipt by the Property Trustee, on behalf of the Issuer, of
an opinion of counsel, rendered by a law firm having a national tax and
securities practice (which opinion shall not have been rescinded by such law
firm), to the effect that, as a result of any amendment to, or change
(including any announced prospective change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein affecting taxation, or as a result of any official
administrative pronouncement or judicial decision interpreting or applying such
laws or regulations, which amendment or change is effective or such
pronouncement or decision is announced on or after the date of issuance of the
Preferred Securities under the Trust Agreement, there is more than an
insubstantial risk in each case after the date hereof that (i) the Issuer is,
or will be within 90 days of
 
                                       25
<PAGE>
 
the date thereof, subject to United States Federal income tax with respect to
income received or accrued on the Debentures, (ii) interest payable by Host
Marriott on such Debentures is not, or within 90 days of the date thereof will
not be, deductible by Host Marriott, in whole or in part, for United States
Federal income tax purposes; or (iii) the Issuer is, or will be within 90 days
of the date thereof, subject to more than a de minimis amount of other taxes,
duties or other governmental charges. "Investment Company Event" means the
receipt by the Property Trustee, on behalf of the Issuer, of an opinion of
counsel, rendered by a law firm having a recognized national tax and securities
practice (which opinion shall not have been rescinded by such law firm), to the
effect that, as a result of the occurrence of a change in law or regulation or
a change in interpretation or application of law or regulation by any
legislative body, court, governmental agency or regulatory authority (a "Change
in 1940 Act Law"), that there is more than an insubstantial risk that the
Issuer is or will be considered an "investment company" that is required to be
registered under the Investment Company Act of 1940, as amended (the
"Investment Company Act"), which Change in 1940 Act Law becomes effective on or
after the date of original issuance of the Preferred Securities.
 
  As a part of President Clinton's Fiscal 1997 Budget Proposal, the Treasury
Department proposed legislation that, among other things, would have treated as
equity for United States Federal income tax purposes certain debt instruments
with a maximum term of more than 20 years that are not shown as indebtedness on
the consolidated balance sheet of the Issuer. The proposed legislation was to
be effective for debt instruments issued on or after December 7, 1995. Although
this legislation was not enacted as part of the Fiscal 1997 Budget, there can
be no assurance that a similar proposal would not be enacted in the future,
that such future legislation would not have a retroactive effective date and
that such future legislation would not prevent Host Marriott from deducting
interest on the Debentures. This would constitute a Tax Event and would permit
the Issuer to exchange the Preferred Securities, in whole or in part, for the
Debentures or redeem, in whole or in part, the Preferred Securities and
corresponding Debentures.
 
  "Additional Sums" means the additional amounts as may be necessary in order
that the amount of Distributions then due and payable by the Issuer on the
outstanding Preferred Securities and Common Securities of the Issuer shall not
be reduced as a result of any additional taxes, duties and other governmental
charges to which the Issuer has become subject as a result of a Tax Event.
 
  Holders of Preferred Securities, by purchasing such Preferred Securities,
will be deemed to have agreed to be bound by these exchange provisions in
regard to the exchange of such Preferred Securities for Debentures on the terms
described above.
 
DISTRIBUTION OF DEBENTURES
 
  At any time, Host Marriott will have the right to terminate the Issuer and,
after satisfaction of the liabilities of creditors of the Issuer as provided by
applicable law, cause the Debentures to be distributed to the holders of the
Preferred Securities in liquidation of the Issuer. Under current United States
Federal income tax law and interpretations and assuming, as expected, the
Issuer is treated as a grantor trust, a distribution of the Debentures should
not be a taxable event to the Issuer and holders of the Preferred Securities.
Should there be a change in law, a change in legal interpretation, a Special
Event or other circumstances, however, the distribution could be a taxable
event to holders of the Preferred Securities. See "Certain Federal Income Tax
Consequences--Redemption of Preferred Securities for Debentures or Cash."
 
  After the liquidation date fixed for any distribution of Debentures for
Preferred Securities (i) such Preferred Securities will no longer be deemed to
be outstanding, (ii) DTC or its nominee, as the record holder of such Preferred
Securities, will receive a registered global certificate or certificates
representing the Debentures to be delivered upon such distribution and (iii)
any certificates representing such Preferred Securities not held by DTC or its
nominee will be deemed to represent
 
                                       26
<PAGE>
 
the Debentures having a principal amount equal to the liquidation amount of
such Preferred Securities, and bearing accrued and unpaid interest in an amount
equal to the accrued and unpaid Distributions on such Preferred Securities
until such certificates are presented to the Property Trustee for transfer or
reissuance.
 
OPTIONAL REDEMPTION
 
  Except as provided under "--Mandatory Redemption" below, the Preferred
Securities may not be redeemed by the Issuer prior to December 2, 1999.
 
  On and after such date, upon any permitted redemption by Host Marriott of
Debentures, the Preferred Securities are subject to redemption, in whole or in
part, at the following percentages of the liquidation preference thereof plus
accrued and unpaid Distributions, if any, to the date fixed for redemption if
redeemed during the twelve-month period commencing December 2 in each of the
following years indicated:

  The aggregate liquidation preference of the Preferred Securities and Common
Securities so redeemed will equal the aggregate principal amount of Debentures
redeemed by Host Marriott, which may not exceed the amount of the proceeds
derived, directly or indirectly, by Host Marriott or its subsidiaries from the
issuance and sale of common stock within two years preceding the date fixed for
redemption. The Issuer may not redeem the Preferred Securities in part unless
all accrued and unpaid Distributions have been paid in full on all outstanding
Preferred Securities. If fewer than all the outstanding Preferred Securities
are to be redeemed, the Preferred Securities to be so redeemed will be selected
as described under "--Form, Transfer, Exchange and Book-Entry Procedures."
 
  In the event Host Marriott redeems the Debentures in certain circumstances
upon the occurrence of a Tax Event as described under "--Special Event Exchange
or Redemption," the appropriate amount of the Preferred Securities will be
redeemed at 100% of the principal amount thereof together with accrued and
unpaid Distributions to the redemption date.
 
  If at any time following the Conversion Expiration Date, less than 5% of the
Preferred Securities offered hereby remain outstanding, such Preferred
Securities shall be redeemable at the option of the Issuer, in whole but not in
part, at a redemption price of $50 per Preferred Security, and all accrued and
unpaid Distributions.
 
MANDATORY REDEMPTION
 
  Upon repayment at maturity or as a result of the acceleration of the
Debentures upon the occurrence of a "Debenture Event of Default" described
under "Description of the Debentures--Debenture Events of Default," the
Debentures shall be subject to mandatory redemption, in whole but not in part,
by Host Marriott, and the proceeds from such repayment will be applied to
redeem Preferred Securities and Common Securities having an aggregate
liquidation amount equal to the aggregate principal amount of Debentures so
repaid or redeemed at a redemption price equal to the respective liquidation
amount of the Preferred Securities and Common Securities or, in the case of a
redemption of the Debentures, at the redemption price paid with respect to the
Debentures, as described below, together with accrued and unpaid distributions
on the Preferred Securities and Common Securities to the date of redemption. In
the case of acceleration of the Debentures, the Preferred Securities will be
redeemed only when repayment of the Debentures has actually been received by
the Issuer. In addition, as described above under "--Special Event Exchange or

Redemption," upon the occurrence of a Special Event, Preferred Securities shall
be exchanged for Debentures unless, in the case of a Tax Event, Host Marriott
shall have elected to (a) pay any Additional Sums such that the net amounts of
Distributions received by the holders of any Preferred Securities not so
exchanged are not reduced as a result of such Tax Event and shall not have
revoked any such election or failed to make such payments or (b) redeem the
Preferred Securities as further set forth in "Special Event Exchange or
Redemption."
 
REDEMPTION PROCEDURES
 
  Preferred Securities redeemed on the date fixed for redemption shall be
redeemed at the redemption price with the applicable proceeds from the
contemporaneous redemption of the Debentures. Redemptions of the Preferred
Securities shall be made and the redemption price shall be payable on the
redemption date only to the extent that the Issuer has funds on hand available
for the payment of such redemption price. See also "--Subordination of Common
Securities."
 
  Notice of any redemption (optional or mandatory) of Preferred Securities
(which notice will be irrevocable) will be given by the Property Trustee to
each record holder of Preferred Securities that are being redeemed not fewer
than 30 nor more than 60 days prior to the redemption date. If the Property
Trustee gives a notice of redemption in respect of the Preferred Securities,
then, by 12:00 noon, New York City time, on the redemption date, to the extent
funds are available, the Property Trustee will deposit irrevocably with DTC or
the Conversion Agent, as the case may be, funds sufficient to pay the
applicable redemption price and will give DTC or the Conversion Agent, as the
case may be, irrevocable instructions and authority to pay the redemption price
to the holders of such Preferred Securities. See "--Form, Transfer, Exchange
and Book-Entry Procedures." If such Preferred Securities are no longer in book-
entry form, the Property Trustee, to the extent funds are available, will
irrevocably deposit with the Paying Agent 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 certificates evidencing such Preferred Securities.
Notwithstanding the foregoing, Distributions payable on or prior to the
redemption date for any Preferred Securities called for redemption shall be
payable to the holders of such Preferred Securities as of the relevant record
dates for the related distribution dates. If notice of redemption shall have
been given and funds deposited as required, then upon the date of such deposit,
all rights of the holders of such Preferred Securities so called for redemption
will cease, except the right of the holders of such Preferred Securities to
receive the redemption price, but without interest on such redemption price,
and such Preferred Securities will cease to be outstanding. In the event that
any date fixed for redemption of Preferred Securities is not a Business Day,
then payment of the redemption price on such date will be made on the next
succeeding day which 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 the event that payment of the redemption price in
respect of Preferred Securities called for redemption is improperly withheld or
refused and not paid either by the Issuer or by Host Marriott pursuant to the
Guarantee as described under "Description of the Guarantee," Distributions on
such Preferred Securities will continue to accrue at the then applicable rate,
from the redemption date originally established by the Issuer 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.
 
  Subject to applicable law (including, without limitation, United States
Federal securities law), Host Marriott or its subsidiaries may at any time and
from time to time purchase outstanding Preferred Securities by tender, in the
open market or by private agreement.
 
  Payment of the redemption price on the Preferred Securities and any
distribution or exchange of Debentures to holders of Preferred Securities shall
be made to the applicable record holders thereof as they
 
                                       28
<PAGE>
 
appear on the register for such Preferred Securities on the relevant record
date, which shall be the fifteenth day (whether or not a Business Day) prior to
the redemption date or liquidation date, as applicable.
 
  If less than all of the Preferred Securities and Common Securities listed by
the Issuer are to be redeemed on a redemption date, then the aggregate
liquidation amount of such Preferred Securities and Common Securities to be
redeemed shall be allocated pro rata among the Preferred Securities and the
Common Securities. The particular Preferred Securities to be redeemed shall be
selected not more than 60 days prior to the redemption date by the Property
Trustee from the outstanding Preferred Securities not previously called for
redemption, by lot or by such method as the Property Trustee shall deem fair
and appropriate and which may provide for the selection for redemption of
portions (equal to $50 or an integral multiple of $50 in excess thereof) of the
liquidation amount of the Preferred Securities. The Property Trustee shall
promptly notify the Conversion Agent 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; it being
understood that, in the case of Preferred Securities held by DTC (or any
successor) or its nominee, the distribution of the proceeds of such redemption
will be made in accordance with the procedures of DTC or its nominee. For all
purposes of the 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 aggregate liquidation amount of Preferred Securities
which has been or is to be redeemed.
 
  Notice of any redemption of Debentures will be mailed at least 30 days but
not more than 60 days before the redemption date to each holder of Debentures
to be redeemed at its registered address. Unless Host Marriott defaults in
payment of the redemption price, on and after the redemption date interest
ceases to accrue on such Debentures or portions thereof called for redemption.
 
SUBORDINATION OF COMMON SECURITIES
 
  Payment of Distributions on, and the redemption price of, the Preferred
Securities and Common Securities, as applicable, shall be made pro rata based
on the liquidation amount of such Preferred Securities and Common Securities;
provided, however, that if on any distribution date or redemption date a
Declaration Event of Default shall have occurred and be continuing, no payment
of any Distribution on, or redemption price of, any of the Common Securities,
and no other payment on account of the redemption, liquidation or other
acquisition of such Common Securities, shall be made unless payment in full in
cash of all accumulated and unpaid Distributions on all of the 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 of the outstanding Preferred Securities then
called for redemption, shall have been made or provided for, and all funds
available to the Property Trustee shall first be applied to the payment in full
in cash of all Distributions on, or redemption price of, the Preferred
Securities then due and payable.
 
  In the case of any Declaration Event of Default, Host Marriott as holder of
the Common Securities will be deemed to have waived any right to act with
respect to any such Declaration Event of Default until all such Declaration
Events of Default with respect to the Preferred Securities have been cured,
waived or otherwise eliminated. Until any such Declaration Events of Default
with respect to the Preferred Securities have been so cured, waived or
otherwise eliminated, the Property Trustee shall act solely on behalf of the
holders of the Preferred Securities and not on behalf of Host Marriott as
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.
 
LIQUIDATION DISTRIBUTION UPON TERMINATION
 
  In the event of any voluntary or involuntary liquidation, termination,
dissolution or winding up of the Issuer (each, a "Liquidation"), the holders of
the Preferred Securities at that time will be entitled to
 
                                       29
<PAGE>
 
receive out of the assets of the Issuer, after satisfaction of liabilities to
creditors, distributions in an amount equal to the aggregate of the stated
liquidation amount of $50 per Preferred Security plus accrued and unpaid
Distributions thereon to the date of payment (the "Liquidation Distribution"),
unless, in connection with such Liquidation, Debentures in an aggregate
principal amount equal to the aggregate stated liquidation amount of, with an
interest rate identical to the distribution rate of, and accrued and unpaid
interest equal to accrued and unpaid Distributions on, the Preferred
Securities, have been distributed on a pro rata basis to the holders of
Preferred Securities in exchange for such Preferred Securities. See "--
Distribution of Debentures."
 
  If such Liquidation Distribution can be paid only in part because the Issuer
has insufficient assets available to pay in full the aggregate Liquidation
Distribution, then the amounts payable directly by the Issuer on the Preferred
Securities shall be paid on a pro rata basis. The holder(s) of the Common
Securities will be entitled to receive Liquidation Distributions upon any such
liquidation pro rata with the holders of the 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.
 
  Pursuant to the Trust Agreement, the Issuer shall automatically terminate
upon expiration of its term and shall terminate on the first to occur of: (i)
certain events of bankruptcy, dissolution or liquidation of Host Marriott; (ii)
the distribution of Debentures to the holders of the Preferred Securities and
Common Securities, if Host Marriott, as Depositor, has given written direction
to the Property Trustee to terminate the Issuer (which direction is optional
and wholly within the discretion of Host Marriott, as Depositor); (iii) the
redemption, conversion, or exchange of all of the Preferred Securities and
Common Securities; (iv) the entry by a court of competent jurisdiction of an
order for the dissolution of the Issuer; and (v) the occurrence of a Special
Event except in the case of a Tax Event following which Host Marriott has
elected to pay any Additional Sums such that the net amount received by holders
of Preferred Securities in respect of Distributions is not reduced as a result
of such Tax Event and Host Marriott has not revoked any such election or failed
to make such payment.
 
DECLARATION EVENTS OF DEFAULT; NOTICE
 
  An event of default under the Indenture (a "Debenture Event of Default")
constitutes an event of default under the Trust Agreement with respect to the
Preferred Securities and the Common Securities (a "Declaration Event of
Default"), whatever the reason for such Debenture Event of Default and whether
it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body.
 
  Within ten days after the occurrence of any Declaration Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit
notice of such Declaration Event of Default to the holders of the Preferred
Securities, the Administrative Trustees and Host Marriott, as Depositor, unless
such Declaration Event of Default shall have been cured or waived. Host
Marriott, as Depositor, and the Administrative Trustees, on behalf of the
Issuer, are required to file annually with the Property Trustee a certificate
as to whether or not they are in compliance with all the conditions and
covenants applicable to them under the Trust Agreement.
 
  If a Declaration Event of Default has occurred and is continuing, the
Preferred Securities shall have a preference over the Common Securities upon
termination of the Issuer as described above. See "--Liquidation Distribution
Upon Termination." The existence of a Declaration Event of Default does not
entitle the holders of Preferred Securities to accelerate the maturity thereof.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
  If a Declaration Event of Default has occurred and is continuing, then the
holders of Preferred Securities would rely on the enforcement by the Property
Trustee of its rights as a holder of the
 
                                       30
<PAGE>
 
Debentures against Host Marriott. In addition, the holders of a majority in
aggregate liquidation amount of the Preferred Securities will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Property Trustee or to direct the exercise of any trust or
power conferred upon the Property Trustee under the Trust Agreement, including
the right to direct the Property Trustee to exercise the remedies available to
it as a holder of the Debentures. If the Property Trustee fails to enforce its
rights as holder of the Debentures after a request therefor by a holder of
Preferred Securities, such holder may proceed to enforce such rights directly
against Host Marriott. Notwithstanding the foregoing, if a Declaration Event of
Default has occurred and is continuing and such event is attributable to the
failure of Host Marriott to pay interest or principal on the Debentures on the
date such interest or principal is otherwise payable (or in the case of
redemption, on the redemption date), then a holder of Preferred Securities may
directly institute a Direct Action against Host Marriott for enforcement of
payment to such holder of the principal of or interest on the Debentures having
a principal amount equal to the aggregate liquidation amount of the Preferred
Securities of such holder on or after the respective due date specified in the
Debentures. In connection with such Direct Action, Host Marriott will be
subrogated to the rights of such holder of Preferred Securities under the Trust
Agreement to the extent of any payment made by Host Marriott to such holder of
Preferred Securities in such Direct Action. The holders of Preferred Securities
will not be able to exercise directly against Host Marriott any other remedy
available to the Property Trustee unless the Property Trustee first fails to do
so.
 
MERGER OR CONSOLIDATION OF ISSUER TRUSTEES
 
  Any corporation into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which such Issuer Trustee shall be a
party, or any corporation succeeding to all or substantially all the corporate
trust business of such Issuer Trustee, shall be the successor of such Issuer
Trustee under the Declaration, provided such corporation shall be otherwise
qualified and eligible.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE ISSUER
 
  The Issuer may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described below. The Issuer may, at the request of Host Marriott, with the
consent of the Administrative Trustees and without the consent of the Property
Trustee, the Delaware Trustee or the holders of the Preferred Securities, merge
with or into, consolidate, 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 (i) such successor
entity either (a) expressly assumes all of the obligations of the Issuer with
respect to the Preferred Securities or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the
Preferred Securities (the "Successor Securities") so long as the Successor
Securities rank the same as the Preferred Securities rank in priority with
respect to Distributions and payments upon liquidation, redemption and
otherwise, (ii) Host Marriott expressly appoints a trustee of such successor
entity possessing the same powers and duties as the Property Trustee as the
holder of the Debentures, (iii) the Successor Securities are listed, 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, if any, (iv) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not cause the
Preferred Securities (including any Successor Securities) to be downgraded by
any nationally recognized statistical rating organization, (v) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does
not adversely affect the rights, preferences and privileges of the holders of
the Preferred Securities (including any Successor Securities) in any material
respect, (vi) such successor entity has a purpose identical to that of the
 
                                       31
<PAGE>
 
Issuer, (vii) prior to such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, Host Marriott has received an opinion from
independent counsel to the Issuer experienced in such matters to the effect
that (a) such merger, consolidation, 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 (other than with respect to any dilution of
the holders interest in the new entity) and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease,
neither the Issuer nor such successor entity will be required to register as an
investment company under the Investment Company Act, and (viii) Host Marriott
or any permitted successor or assignee owns all of the Common Securities of
such successor entity and guarantees the obligations of such successor entity
under the Successor Securities at least to the extent provided by the
Guarantee. Notwithstanding the foregoing, the Issuer shall not, except with the
consent of holders of 100% in aggregate liquidation amount of the Preferred
Securities, consolidate, amalgamate, merge with or into, be replaced by or
convey, transfer or lease its properties and assets substantially as an
entirety to any other entity or permit any other entity to consolidate,
amalgamate, merge with or into, or replace it if such consolidation,
amalgamation, merger, replacement, conveyance, transfer or lease would cause
the Issuer or the successor entity to be classified as other than a grantor
trust for United States Federal income tax purposes.
 
VOTING RIGHTS; AMENDMENT OF THE TRUST AGREEMENT
 
  Except as provided below and under "Description of the Guarantee--Amendments
and Assignment" and as otherwise required by law and the Trust Agreement, the
holders of the Preferred Securities have no voting rights.
 
  The Trust Agreement may be amended from time to time by Host Marriott and the
Issuer Trustees, without the consent of the holders of the Preferred Securities
(i) to cure any ambiguity, correct or supplement any provisions in the Trust
Agreement that may be inconsistent with any other provision, or to make any
other provisions with respect to matters or questions arising under the Trust
Agreement that shall not be inconsistent with the other provisions of the Trust
Agreement, (ii) to modify, eliminate or add to any provision of the Trust
Agreement to such extent as shall be necessary to ensure that the Issuer will
be classified for United States Federal income tax purposes as a grantor trust
at all times that any Preferred Securities and Common Securities are
outstanding or to ensure that the Issuer will not be required to register as an
"investment company" under the Investment Company Act or be classified as other
than a grantor trust for United States Federal income tax purposes or (iii) to
qualify or maintain the qualification of the Trust Agreement under the Trust
Indenture Act; provided, however, that in the case of clause (i), such action
shall not adversely affect in any material respect the interests of any holder
of Preferred Securities or Common Securities, and any amendments of the Trust
Agreement shall become effective when notice thereof is given to the holders of
Preferred Securities and Common Securities. The Trust Agreement may be amended
by the Issuer Trustees and Host Marriott with (i) the consent of holders
representing not less than a majority (based upon liquidation amounts) of the
outstanding Preferred Securities and Common Securities, acting as a single
class, and (ii) receipt by the Issuer Trustees of an opinion of counsel to the
effect that such amendment or the exercise of any power granted to the Issuer
Trustees in accordance with such amendment will not affect the Issuer's status
as a grantor trust for United States Federal income tax purposes or the
Issuer's exemption from the status of an "investment company" under the
Investment Company Act; provided further that (a) without the consent of each
holder of Preferred Securities and Common Securities, the Trust Agreement may
not be amended to (i) change the amount or timing of any Distribution on the
Preferred Securities and Common Securities or otherwise adversely affect the
amount of any Distribution required to be made in respect of the Preferred
Securities and Common Securities as of a specified date or (ii) restrict the
right of a holder of Preferred Securities and Common Securities to institute
suit for the enforcement of any such payment on or after such date.
 
  If any proposed amendment of the Trust Agreement provides for, or the Issuer
Trustees otherwise propose to effect, the dissolution, winding-up or
termination of the Issuer, other than pursuant to the
 
                                       32
<PAGE>
 
terms of the Trust Agreement, then the holders of the then 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 the majority in aggregate liquidation amount of the
Preferred Securities.
 
  The holders of a majority in aggregate liquidation amount of Preferred
Securities have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Property Trustee or to direct
the exercise of any trust or power conferred upon the Property Trustee under
the Trust Agreement, including the right to direct the Property Trustee to
exercise the remedies available to it as a holder of the Debentures. So long as
any Debentures are held by the Property Trustee, the Issuer Trustees may not
(i) direct the time, method and place of conducting any proceeding for any
remedy available to the Debenture Trustee or executing any trust or power
conferred on the Debenture Trustee with respect to such Debentures, (ii) waive
any past default that 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,
modification or termination of the Indenture or the Debentures where such
consent shall be required, without in each case, obtaining the prior approval
of the holders of a majority in aggregate liquidation amount of all outstanding
Preferred Securities (except in the case of clause (iv), which consent, in the
event that no Declaration Event of Default shall occur and be continuing, shall
be of the holders of Preferred Securities and Common Securities, voting
together as a single class); 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 the Preferred Securities. The Issuer
Trustees may not revoke any action previously authorized or approved by a vote
of the holders of the Preferred Securities except by subsequent vote of the
holders of the Preferred Securities. The Property Trustee shall notify each
holder of record of the Preferred Securities of any notice of default with
respect to the Debentures.
 
  A waiver of a Debenture Event of Default will constitute a waiver of the
corresponding Declaration Event of Default.
 
  Any required approval or direction of holders of Preferred Securities may be
given at a separate meeting of holders of Preferred Securities convened for
such purpose, at a meeting of all of the holders of the Preferred Securities
and the Common Securities or pursuant to written consent. The Property Trustee
will cause a notice of any meeting at which holders of Preferred Securities are
entitled to vote, or of any matter upon which action by written consent of such
holders is to be taken, to be given to each holder of record of Preferred
Securities in the manner set forth in the Trust Agreement.
 
  No vote or consent of the holders of Preferred Securities is required for the
Issuer to redeem and cancel the Preferred Securities in accordance with the
Trust Agreement.
 
  Notwithstanding that holders of Preferred Securities are entitled to vote or
consent under any of the circumstances described above, any of the Preferred
Securities that are owned at such time by Host Marriott, the Issuer Trustees or
any affiliate of any Issuer Trustee shall, for purposes of such vote or
consent, be treated as if such Preferred Securities were not outstanding.
 
  The procedures by which holders of Preferred Securities may exercise their
voting rights are described below. See "--Form, Transfer, Exchange and Book-
Entry Procedures."
 
  Holders of the Preferred Securities have no rights to appoint or remove the
Issuer Trustees, who may be appointed, removed or replaced solely by Host
Marriott, as the direct or indirect holder of all the Common Securities.
 
PAYMENT AND PAYING AGENCY
 
  Payments in respect of the Preferred Securities represented by the Global
Certificates shall be made to DTC, which shall credit the relevant accounts at
DTC on the applicable distribution dates or,
 
                                       33
<PAGE>
 
in the case of Certificated Securities, such payments shall be made by check
mailed to the address of the holder entitled thereto as such address shall
appear on the Securities Register. The paying agent (the "Paying Agent")
initially is the Property Trustee and any co-paying agent chosen by the
Property Trustee and acceptable to the Administrative Trustees and Host
Marriott. The Paying Agent is permitted to resign as Paying Agent upon 30 days'
written notice to the Property Trustee and Host Marriott. In the event that the
Property Trustee shall no longer be the Paying Agent, the Administrative
Trustees shall appoint a successor (which shall be a bank or trust company
acceptable to the Administrative Trustees and Host Marriott) to act as Paying
Agent.
 
 CERTAIN BOOK-ENTRY PROCEDURES FOR GLOBAL CERTIFICATES
 
  The description of book-entry procedures in this Prospectus includes
summaries of certain rules and operating procedures of DTC that affect
transfers of interests in the global certificate or certificates issued in
connection with sales of Preferred Securities made pursuant to this Prospectus.
Substantially all of the Preferred Securities were issued as fully registered
securities registered in the name of Cede & Co. (as nominee for DTC). Fully
registered global Preferred Security certificates (the "Global Certificates")
were issued, representing such Preferred Securities and were deposited with
DTC.
 
  DTC has advised the Issuer and the Company as follows: DTC is a limited
purpose trust company organized under the laws of the State of New York, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the Uniform Commercial Code and a "Clearing Agency" registered
pursuant to the provisions of Section 17A of the Exchange Act. DTC was created
to hold securities for its participants ("participants") and facilitate the
clearance and settlement of securities transactions between participants
through electronic book-entry changes in accounts of its participants, thereby
eliminating the need for physical transfer and delivery of certificates.
Participants include securities brokers and dealers, banks, trust companies and
clearing corporations and may include certain other organizations. Indirect
access to the DTC system is available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a participant, either directly or indirectly ("indirect
participants").
 
  DTC has advised the Issuer and the Company that its current practice, upon
the issuance of the Restricted Global Certificate and the Regulation S Global
Certificate, is to credit, on its internal system, the respective principal
amount of the individual beneficial interests represented by such Global
Certificates to the accounts with DTC of the participants through which such
interests are to be held. Ownership of beneficial interests in the Global
Certificates will be shown on, and the transfer of that ownership will be
effected only through, records maintained by DTC or its nominees (with respect
to interests of participants) and the records of participants and indirect
participants (with respect to interests of persons other than participants).
 
  [DTC has no knowledge of the actual Beneficial Owners of the Preferred
Securities; DTC's records reflect only the identity of the Participants to
whose accounts such Preferred Securities are credited, which may or may not be
the Beneficial Owners. The Participants and Indirect Participants will remain
responsible for keeping account of their holdings on behalf of their
customers.]
 
  As long as DTC, or its nominee, is the registered holder of a Global
Certificate, DTC or such nominee, as the case may be, will be considered the
sole owner and holder of the Preferred Securities represented by such Global
Certificate for all purposes under the Trust Agreement and the Preferred
Securities. [No beneficial owner of an interest in a Global Certificate will be
able to transfer that interest except in accordance with DTC's applicable
procedures, in addition to those provided for under the Trust Agreement.]
 
  Except in certain limited circumstances, owners of beneficial interests in a
Global Certificate will not be entitled to have any portions of such Global
Certificate registered in their names, will not receive
 
                                       34
<PAGE>
 
or be entitled to receive physical delivery of Preferred Securities in
definitive form and will not be considered the owners or holders of the Global
Certificate (or any Preferred Securities represented thereby) under the Trust
Agreement or the Preferred Securities.
 
  Investors may hold their interests in the Restricted Global Certificate
directly through DTC, if they are participants in such system, or indirectly
through organizations (including Euroclear and CEDEL) which are participants in
such system. Investors may hold their interests in the Regulation S Global
Certificate through CEDEL or Euroclear, if they are participants in such
systems, or indirectly through organizations which are participants in such
systems. After the expiration of the Restricted Period (but not earlier),
investors may also hold their interests in the Regulation S Global Certificate
through organizations other than CEDEL and Euroclear that are participants in
the DTC system. CEDEL and Euroclear will hold interests in the Regulation S
Global Certificate on behalf of their participants through customers'
securities accounts in their respective names on the books of their respective
depositories. The depositories, in turn, will hold such interests in the
Regulation S Global Certificate in customers' securities accounts in the
depositories' names on the books of DTC. All interests in a Global Certificate,
including those held through Euroclear or CEDEL, will be subject to the
procedures and requirements of DTC. Those interests held through Euroclear and
CEDEL will also be subject to the procedures and requirements of such system.
Transfers and exchanges of interests in a Global Certificate will also be
subject to the procedures described above under "--Exchanges between the
Restricted Global Certificate and the Regulation S Global Certificate," if
applicable.
 
  The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interests in a Global Certificate to such persons may be
limited to that extent. Because DTC can act only on behalf of its participants,
which in turn act on behalf of indirect participants and certain banks, the
ability of a person having beneficial interests in a Global Certificate to
pledge such interest to persons or entities that do not participate in the DTC
system, or otherwise take actions in respect of such interests, may be affected
by the lack of a physical certificate evidencing such interests.
 
  Payments of Distributions on Global Certificates will be made to DTC or its
nominee as the registered owner thereof. Neither the Issuer, the Company, the
Property Trustee nor any of their respective agents will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global
Certificates or for maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.
 
  The Issuer and the Company expect that DTC or its nominee, upon receipt of
any payment of Distributions in respect of a Global Certificate representing
any Preferred Securities held by it or its nominee, will immediately credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of such Global
Certificate for such Preferred Securities as shown on the records of DTC or its
nominee. The Issuer and the Company also expects that payments by participants
to owners of beneficial interests in such Global Certificate held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers
registered in "street name." Such payments will be the responsibility of such
participants.
 
  Except for trades involving only Euroclear and CEDEL participants, interests
in the Global Certificates will trade in DTC's Same-Day Funds Settlement System
and secondary market trading activity in such interests will therefore settle
in immediately available funds, subject in all cases to the rules and
procedures of DTC and its participants. Transfers between participants in DTC
will be effected in accordance with DTC's procedures, and will be settled in
same-day funds. Transfers between participants in Euroclear and CEDEL will be
effected in the ordinary way in accordance with their respective rules and
operating procedures.
 
 
                                       35
<PAGE>
 
  Subject to compliance with the transfer and exchange restrictions applicable
to the Preferred Securities described elsewhere herein, cross-market transfers
between DTC participants, on the one hand, and Euroclear or CEDEL participants,
on the other hand, will be effected by DTC in accordance with DTC's rules on
behalf of Euroclear or CEDEL, as the case may be, by its respective depositary;
however, such cross-market transactions will require delivery of instructions
to Euroclear or CEDEL, as the case may be, by the counterparts in such system
in accordance with the rules and procedures and within the established
deadlines (Brussels time) of such system. Euroclear or CEDEL, as the case may
be, will, if the transaction meets its settlement requirements, deliver
instructions to its respective depository to take action to effect final
settlement on its behalf by delivering or receiving interests in the relevant
Global Certificate in DTC, and making or receiving payment in accordance with
normal procedures for same-day funds settlement applicable to DTC. Euroclear
participants and CEDEL participants may not deliver instructions directly to
the depositories for Euroclear or CEDEL.
 
  Because of time zone differences, the securities account of a Euroclear or
CEDEL participant purchasing an interest in a Global Certificate from a DTC
participant will be credited, and any such crediting will be reported to the
relevant Euroclear or CEDEL participant, during the securities settlement
processing day (which must be a business day for Euroclear and CEDEL)
immediately following the DTC settlement date. Cash received in Euroclear or
CEDEL as a result of sales of interests in a Global Certificate by or through a
Euroclear or CEDEL participant to a DTC participant will be received with value
on the DTC settlement date but will be available in the relevant Euroclear or
CEDEL cash account only as of the business day for Euroclear or CEDEL following
the DTC settlement date.
 
  DTC has advised the Issuer and the Company that it will take any action
permitted to be taken by a holder of Certificates (including the presentation
of Preferred Securities for exchange as described below and the conversion of
Preferred Securities) only at the direction of one or more participants to
whose account with DTC interests in the Global Certificates are credited and
only in respect of such portion of the aggregate liquidation amount of the
Preferred Securities as to which such participant or participants has or have
given such direction. However, if there is a Declaration Event of Default, DTC
reserves the right to exchange the Global Certificates for legended Preferred
Securities in certificated form, and to distribute such Preferred Securities to
its participants.
 
  Although DTC, Euroclear and CEDEL have agreed to the foregoing procedures in
order to facilitate transfers of beneficial ownership interests in the Global
Certificates among participants of DTC, Euroclear and CEDEL, they are under no
obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. None of the Issuer, the Company,
the Property Trustee nor any of their respective agents will have any
responsibility for the performance by DTC, Euroclear and CEDEL, their
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations, including maintaining,
supervising or reviewing the records relating to, or payments made on account
of, beneficial ownership interests in Global Certificates.
 
  Redemption notices shall be sent to Cede & Co. as the registered holder of
the Preferred Securities. If less than all of the Preferred Securities are
being redeemed, DTC's current practice is to determine by lot the amount of the
interest of each Direct Participant to be redeemed.
 
  Although voting with respect to the Preferred Securities is limited to the
holders of record of the Preferred Securities, in those instances in which a
vote is required, neither DTC nor Cede & Co. will itself consent or vote with
respect to Preferred Securities. Under its usual procedures, DTC would mail an
omnibus proxy (the "Omnibus Proxy") to the Property Trustee as soon as possible
after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or
voting rights to those Direct Participants to whose accounts such Preferred
Securities are credited on the record date (identified in a listing attached to
the Omnibus Proxy).
 
                                       36
<PAGE>
 
  Conveyance of notices and other communications by DTC to participants, by
participants to indirect participants, and by participants and indirect
participants to beneficial owners of the Preferred Securities and the voting
rights of participants, indirect participants and beneficial owners of
Preferred Securities will be governed by arrangements among them, subject to
any statutory or regulatory requirements as may be in effect from time to time.
 
  DTC may discontinue providing its services as securities depositary with
respect to the Preferred Securities at any time by giving reasonable notice to
the Property Trustee and Host Marriott. In the event that a successor
securities depositary is not obtained, definitive Preferred Securities
certificates representing such Preferred Securities are required to be printed
and delivered. Host Marriott, at its option, may decide to discontinue use of
the system of book-entry transfers through DTC (or a successor depositary).
After a Debenture Event of Default, the holders of a majority in liquidation
amount of Preferred Securities may determine to discontinue the system of book-
entry transfers through DTC. In any such event, definitive certificates for the
Preferred Securities will be printed and delivered.
 
 TRANSFER AGENT, REGISTRAR AND PAYING, CONVERSION AND EXCHANGE AGENT
 
  The Property Trustee presently acts as transfer agent, registrar, paying
agent, conversion agent and exchange agent for the Preferred Securities.
 
  Registration of transfers or exchanges of Preferred Securities will be
effected without charge by or on behalf of the Issuer, but upon payment of any
tax or other governmental charges that may be imposed in connection with any
transfer or exchange. The Issuer will not be required to register or cause to
be registered the transfer of the Preferred Securities after such Preferred
Securities have been called for redemption.
 
 INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
  Host Marriott and certain of its subsidiaries may maintain deposit accounts
and conduct other banking and corporate securities transactions and
relationships with the Property Trustee in the ordinary course of their
businesses. The Property Trustee, other than during the occurrence and
continuance of a Declaration Event of Default, undertakes to perform only such
duties as are specifically set forth in the Trust Agreement and, after such
Declaration Event of Default, must exercise the same degree of care and skill
as a prudent person would exercise or use in the conduct of his or her own
affairs. Subject to this provision, the Property Trustee is under no obligation
to exercise any of the powers vested in it by the Trust Agreement at the
request of any holder of Preferred Securities unless it is offered reasonable
indemnity against the costs, expenses and liabilities that might be incurred
thereby. If no Declaration Event of Default has occurred and is continuing and
the Property Trustee is required to decide between alternative causes of
action, construe ambiguous provisions in the Trust Agreement or is unsure of
the application of any provision of the Trust Agreement, and the matter is not
one on which holders of Preferred Securities are entitled under the Trust
Agreement to vote, then the Property Trustee shall take such action as is
directed by Host Marriott and, if not so directed, shall take such action as it
deems advisable and in the best interests of the holders of the Preferred
Securities and the Common Securities and will have no liability except for its
own bad faith, negligence or willful misconduct.
 
 MISCELLANEOUS
 
  The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate the Issuer in such a way that the Issuer will not be
deemed to be an "investment company" required to be registered under the
Investment Company Act or classified as an association taxable as a corporation
for United States Federal income tax purposes and so that the Debentures will
be treated as indebtedness of Host Marriott for United States Federal income
tax purposes. In this connection,
 
                                       37
<PAGE>
 
Host Marriott and the Administrative Trustees are authorized to take any
action, not inconsistent with applicable law, the certificate of trust of the
Issuer or the Trust Agreement, that Host Marriott and the Administrative
Trustees determine in their discretion to be necessary or desirable for such
purposes, as long as such action does not materially adversely affect the
interests of the holders of the Preferred Securities.
 
  Holders of the Preferred Securities have no preemptive or similar rights.
 
  The Issuer may not borrow money or issue debt or mortgage or pledge any of
its assets.
 
REGISTRATION RIGHTS
 
  In connection with the Original Offering, the Company and the Trust entered
into registration rights agreement with the Purchasers, dated December 2, 1996
(the "Registration Rights Agreement") pursuant to which the Company and the
Trust agreed, at the Company's expense, for the benefit of the holders of the
Preferred Securities, the Debentures issuable in respect of the Preferred
Securities, Host Marriott Common Stock issuable upon conversion of the
Preferred Securities and the Debentures and the Guarantee (together, the
"Registrable Securities"), to file with the Commission on or prior to the date
120 days after the Original Offering Date a shelf registration statement (the
"Shelf Registration Statement") on such form as Host Marriott deems appropriate
covering resale by holders of the Registrable Securities. The Company has
agreed to use its best efforts (i) to cause the Shelf Registration Statement to
be declared effective as promptly as practicable and in no event later than 180
days after the Original Offering Date and (ii) to keep effective the Shelf
Registration Statement until three years after the latest date of original
issuance of the Preferred Securities (or such earlier date as the holders of
Registrable Securities are able to sell all Registrable Securities immediately
without restriction pursuant to Rule 144(k) under the Securities Act or any
successor rule thereto or otherwise) (such period the "Effectiveness Period").
The Issuer and Host Marriott are permitted to suspend the use of the prospectus
(which is a part of the Shelf Registration Statement) in connection with sales
of Registrable Securities by holders during certain periods of time under
certain circumstances relating to pending corporate developments relating to
the Company and public filings with the Commission and similar events. Pursuant
to the Registration Rights Agreement, the Issuer and Host Marriott agreed to
provide to each registered holder copies of such prospectus, notify each
registered holder when the Shelf Registration Statement has become effective,
and take certain other actions as are required to permit unrestricted sales of
the Registrable Securities.
 
  In the Registration Rights Agreement, the Issuer and Host Marriott agreed to
indemnify the holders of Registrable Securities against certain liabilities,
including liabilities under the Securities Act, subject to certain customary
limitations, and each holder of Registrable Securities included in the Shelf
Registration Statement will be obligated to indemnify the Issuer and the
Company, any other holder and any underwriters participating in the offering of
Registrable Securities against any liability with respect to information
furnished by such holder in writing to the Issuer and the Company (including
the information in a Selling Securityholder's Questionnaire) expressly for use
in the Shelf Registration Statement.
 
  If (i) on or prior to the date 120 days after the Closing Date a Shelf
Registration Statement has not been filed with the Commission or (ii) on or
prior to the date 180 days after the Original Offering Date such Shelf
Registration Statement has not been declared effective (each such event, a
"Registration Default"), additional interest ("Liquidated Damages") will accrue
on the Debentures, and, accordingly, additional distributions will accrue on
the Preferred Securities, from and including the day following such
Registration Default until such date as the Shelf Registration Statement is
declared effective. Liquidated Damages will be paid quarterly in arrears, with
the first quarterly payment due on the first interest or distribution payment
date, as applicable, following the date on which such Liquidated Damages begin
to accrue, and will accrue at a rate per annum equal to an additional one-
 
                                       38
<PAGE>
 
quarter of one percent (0.25%) of the principal amount or liquidation amount,
as applicable, to and including the 90th day following such Registration
Default and one-half of one percent (0.50%) thereof from and after the 91st day
following such Registration Default. In the event that the Shelf Registration
Statement ceases to be effective during the Effectiveness Period for more than
90 days, whether or not consecutive, during any 12-month period then the
interest rate borne by the Debentures and the distribution rate borne by the
Preferred Securities will each increase by an additional one-half of one
percent (0.50%) per annum from the 91st day of the applicable 12-month period
such Shelf Registration Statement ceases to be effective until such time as the
Shelf Registration Statement again becomes effective.
 
  This summary of certain provisions of the Registration Rights Agreement does
not purport to be complete and is subject to, and qualified in its entirety by
reference to, all the provisions of the Registration Rights Agreement, a copy
of the form of which is incorporated by reference herein as an exhibit to the
Registration Statement.
 
GOVERNING LAW
 
  The Trust Agreement and the Preferred Securities are governed by, and
construed in accordance with, the internal laws of the State of Delaware
without regard to its conflict of laws principles and excluding sections 3540
and 3561 of Title 12 of the Delaware General Corporate Laws.

                          DESCRIPTION OF THE GUARANTEE
 
  The Guarantee was executed and delivered by Host Marriott concurrently with
the issuance by the Issuer of the Preferred Securities for the benefit of the
holders from time to time of such Preferred Securities. IBJ Schroder Bank &
Trust Company is the trustee ("Guarantee Trustee") under the Guarantee. This
summary of certain provisions of the Guarantee does not purport to be complete
and is subject to, and qualified in its entirety by reference to, all of the
provisions of the Guarantee. The Guarantee Trustee will hold the Guarantee for
the benefit of the holders of the Preferred Securities.
 
GENERAL
 
  Pursuant to and to the extent set forth in the Guarantee, Host Marriott
irrevocably agreed to pay in full on a subordinated basis, to the extent set
forth herein, the Guarantee Payments (as defined below) to the holders of the
Preferred Securities, as and when due, regardless of any defense, right of set-
off or counterclaim that the Issuer may have or assert other than the defense
of payment. The following payments with respect to the Preferred Securities, to
the extent not paid by or on behalf of the Issuer (the "Guarantee Payments"),
are subject to the Guarantee: (i) any accumulated and unpaid Distributions
required to be paid on the Preferred Securities, to the extent that the Issuer
has funds on hand available therefor at such time, (ii) the redemption price
with respect to any Preferred Securities called for redemption to the extent
that the Issuer has funds on hand available therefor at such time, or (iii)
upon a voluntary or involuntary dissolution, winding up or liquidation of the
Issuer (unless the Debentures are distributed to holders of the Preferred
Securities), the lesser of (a) the Liquidation Distribution, to the extent that
the Issuer has funds on hand available therefor at such time, and (b) the
amount of assets of the Issuer remaining available for distribution to holders
of Preferred Securities. Host Marriott's obligation to make a Guarantee Payment
may be satisfied by direct payment of the required amounts by Host Marriott to
the holders of the Preferred Securities or by causing the Issuer to pay such
amounts to such holders.
 
  The Guarantee is an irrevocable guarantee on a subordinated basis of the
Issuer's obligations under the Preferred Securities, but it applies only to the
extent that the Issuer has funds sufficient to make such payments, and is not a
guarantee of collection. If Host Marriott does not make interest payments on
the Debentures held by the Issuer, the Issuer will not be able to pay
Distributions on the Preferred Securities and will not have funds legally
available therefor.
 
  Host Marriott has, through the Guarantee, the Trust Agreement, the
Debentures, the Indenture and the Expense Agreement, taken together, fully,
irrevocably and unconditionally guaranteed all of the Issuer's obligations
under the Preferred Securities. No single document standing alone or operating
in conjunction with fewer than all of the other documents constitutes such
guarantee. It is only the combined operation of these documents that has the
effect of providing a full, irrevocable and unconditional guarantee of the
Issuer's obligations under the Preferred Securities. See "Relationship Among
the Preferred Securities, the Debentures and the Guarantee."
 
  The Company has also agreed separately to irrevocably and unconditionally
guarantee the obligations of the Issuer with respect to the Common Securities
to the same extent as the Guarantee, except that upon the occurrence and during
the continuation of a Declaration Event of Default, holders of Preferred
Securities shall have priority over holders of Common Securities with respect
to distributions and payments on liquidation, redemption or otherwise.
 
STATUS OF THE GUARANTEE
 
  The Guarantee constitutes an unsecured obligation of Host Marriott and ranks
subordinate and junior in right of payment to all other liabilities of Host
Marriott and ranks pari passu with any guarantee
 
                                       40
<PAGE>
 
now or hereafter entered into by Host Marriott in respect of any preferred or
preference stock of any affiliate of Host Marriott.
 
  The Guarantee constitutes a guarantee of payment and not of collection (i.e.,
the guaranteed party may institute a legal proceeding directly against the
Guarantor to enforce its rights under the Guarantee without first instituting a
legal proceeding against any other person or entity). The Guarantee is held for
the benefit of the holders of the Preferred Securities. The Guarantee will not
be discharged except by payment of the Guarantee Payments in full to the extent
not paid by the Issuer or upon distribution of the Debentures to the holders of
the Preferred Securities. The Guarantee does not place a limitation on the
amount of additional indebtedness that may be incurred by Host Marriott or any
of its subsidiaries.
 
AMENDMENTS AND ASSIGNMENT
 
  Except with respect to any changes which do not materially adversely affect
the rights of holders of the Preferred Securities (in which case no vote will
be required), the Guarantee may not be amended without the prior approval of
the holders of not less than a majority in aggregate liquidation amount of such
outstanding Preferred Securities. The manner of obtaining any such approval
will be set forth under "Description of the Preferred Securities--Voting
Rights; Amendment of the Trust Agreement." All guarantees and agreements
contained in the Guarantee bind the successors, assigns, receivers, trustees
and representatives of Host Marriott and inure to the benefit of the holders of
the Preferred Securities then outstanding.
 
CERTAIN COVENANTS OF HOST MARRIOTT
 
  Host Marriott covenants in the Guarantee that if and so long as (i) the
Issuer is the holder of all the Debentures, (ii) a Tax Event in respect of the
Issuer has occurred and is continuing and (iii) Host Marriott has elected, and
has not revoked such election, to pay Additional Sums in respect of the
Preferred Securities and Common Securities, Host Marriott will pay to the
Issuer such Additional Sums. Host Marriott also covenants that it will not, and
it will not cause any of its subsidiaries to, (i) declare or pay any dividends
or distributions on, or redeem, purchase, acquire, or make a liquidation
payment with respect to, any of Host Marriott's capital stock or (ii) make any
payment of principal, interest or premium, if any, on or repay or repurchase or
redeem any debt securities (including guarantees of indebtedness for money
borrowed) of Host Marriott that rank pari passu with or junior to the
Debentures (other than (a) any dividend, redemption, liquidation, interest,
principal or guarantee payment by Host Marriott where the payment is made by
way of securities (including capital stock) that rank pari passu with or junior
to the securities on which such dividend, redemption, interest, principal or
guarantee payment is being made, (b) redemptions or purchases of any Rights
pursuant to Host Marriott's Rights Agreement, or any successor to such Rights
Agreement and the declaration of a dividend of such Rights or the issuance of
preferred stock under such plans in the future, (c) payments under the
Guarantee, (d) purchases of Host Marriott Common Stock related to the issuance
of Host Marriott Common Stock under any of Host Marriott's benefit plans for
its directors, officers or employees, (e) as a result of a reclassification of
Host Marriott's capital stock or the exchange or conversion of one series or
class of Host Marriott's capital stock for another series or class of Host
Marriott's capital stock and (f) the purchase of fractional interests in shares
of Host Marriott's capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged)
if at such time (i) there shall have occurred any event of which Host Marriott
has actual knowledge that (a) with the giving of notice or the lapse of time,
or both, would constitute a Debenture Event of Default and (b) in respect of
which Host Marriott shall not have taken reasonable steps to cure, (ii) Host
Marriott shall be in default with respect to its payment of any obligations
under the Guarantee or (iii) Host Marriott shall have given notice of its
selection of an Extension Period as provided in the Indenture with respect to
the Debentures and shall not have rescinded such notice, or such Extension
Period, or any extension thereof, shall be continuing. Host Marriott also
covenants
 
                                       41
<PAGE>
 
(i) for so long as Preferred Securities are outstanding, not to convert
Debentures except pursuant to a notice of conversion delivered to the
Conversion Agent by a holder of Preferred Securities, (ii) to maintain directly
or indirectly 100% ownership of the Common Securities, provided that certain
successors which are permitted pursuant to the Indenture may succeed to Host
Marriott's ownership of the Common Securities, (iii) not to voluntarily
terminate, wind-up or liquidate the Issuer, except (a) in connection with a
distribution of the Debentures to the holders of the Preferred Securities in
liquidation of the Issuer or (b) in connection with certain mergers,
consolidations or amalgamations permitted by the Trust Agreement, (iv) to
maintain the reservation for issuance of the number of shares of Host Marriott
Common Stock that would be required from time to time upon the conversion of
all the Debentures then outstanding, (v) to use its reasonable efforts,
consistent with the terms and provisions of the Trust Agreement, to cause the
Issuer to remain classified as a grantor trust and not as an association
taxable as a corporation for United States Federal income tax purposes and (vi)
to deliver shares of Host Marriott Common Stock upon an election by the holders
of the Preferred Securities to convert such Preferred Securities into Host
Marriott Common Stock.
 
  As part of the Guarantee, Host Marriott agrees that it will honor all
obligations described therein relating to the conversion or exchange of the
Preferred Securities into or for Host Marriott Common Stock or Debentures.
 
EVENTS OF DEFAULT
 
  An event of default under the Guarantee will occur upon the failure of Host
Marriott to perform any of its payment or other obligations thereunder. The
holders of a majority in aggregate liquidation amount of the Preferred
Securities have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Guarantee Trustee in respect of
the Guarantee or to direct the exercise of any trust or power conferred upon
the Guarantee Trustee under the Guarantee.
 
  If the Guarantee Trustee fails to enforce the Guarantee, any holder of the
Preferred Securities may institute a legal proceeding directly against Host
Marriott to enforce its rights under the Guarantee without first instituting a
legal proceeding against the Issuer, the Guarantee Trustee or any other person
or entity. In addition, any record holder of Preferred Securities shall have
the right, which is absolute and unconditional, to proceed directly against
Host Marriott to obtain Guarantee Payments, without first waiting to determine
if the Guarantee Trustee has enforced the Guarantee or instituting a legal
proceeding against the Issuer, the Guarantee Trustee or any other person or
entity. Host Marriott has waived any right or remedy to require that any action
be brought just against the Issuer, or any other person or entity before
proceeding directly against Host Marriott.
 
  Host Marriott, as guarantor, is required to file annually with the Guarantee
Trustee a certificate as to whether or not Host Marriott is in compliance with
all the conditions and covenants applicable to it under the Guarantee.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
  The Guarantee Trustee, other than during the occurrence and continuance of a
default by Host Marriott in performance of the Guarantee, undertakes to perform
only such duties as are specifically set forth in the Guarantee and, after
default with respect to the Guarantee, must exercise the same degree of care
and skill as a prudent person would exercise or use under the circumstances in
the conduct of his or her own affairs. Subject to this provision, the Guarantee
Trustee is under no obligation to exercise any of the powers vested in it by
the Guarantee at the request of any holder of Preferred Securities unless it is
offered reasonable indemnity against the costs, expenses and liabilities that
might be incurred thereby.
 
 
                                       42
<PAGE>
 
TERMINATION OF THE GUARANTEE
 
  The Guarantee will terminate and be of no further force and effect upon full
payment of the redemption price of the Preferred Securities, upon full payment
of the amounts payable upon liquidation of the Issuer, upon the distribution,
if any, of Host Marriott Common Stock to the holders of Preferred Securities in
respect of the conversion of all such holders' Preferred Securities into Host
Marriott Common Stock or upon distribution of Debentures to the holders of the
Preferred Securities in exchange for all of the Preferred Securities. The
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any holder of Preferred Securities must restore payment of
any sums paid under such Preferred Securities or the Guarantee.
 
GOVERNING LAW
 
  The Guarantee will be governed by and construed in accordance with the laws
of the State of New York.
 
                         DESCRIPTION OF THE DEBENTURES
  Set forth below is a description of a the specific terms of the Debentures in
which the Trust invested the proceeds from the issuance and sale of the Trust
Securities. The Debentures are issued under a Junior Subordinated Indenture
(the "Indenture") between Host Marriott and IBJ Schroder Bank & Trust Company
as trustee (the "Debenture Trustee"), copies of which will be available for
inspection at the corporate trust office of the Debenture Trustee in New York,
New York. This summary of certain terms and provisions of the Debentures and
the Indenture does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, the Indenture, attached to this
Registration Statement as an Exhibit. Whenever particular defined terms of the
Indenture are referred to herein, such defined terms are incorporated herein or
therein by reference.
 
GENERAL
 
  The Debentures are unsecured and rank junior and subordinate in right of
payment to all Senior Debt of Host Marriott. The Debentures are limited in
aggregate principal amount to $567.05 million, such amount being the sum of the
aggregate stated liquidation amount of the Preferred Securities and capital
contributed by Host Marriott in exchange for the Common Securities. The
Indenture does not limit the incurrence or issuance of other secured or
unsecured debt of Host Marriott, whether under the Indenture or any existing or
other indenture that Host Marriott may enter into in the future or otherwise.
See "--Subordination."
 
  Concurrently with the issuance of the Preferred Securities, the Issuer has
invested the proceeds thereof and the consideration paid by Host Marriott for
the Common Securities in the Debentures. The Debentures are in the principal
amount equal to the aggregate stated liquidation amount of the Preferred
Securities plus Host Marriott's concurrent investment in the Common Securities.
 
  The Debentures are not subject to any sinking fund provision. The entire
principal amount of the Debentures will mature, and become due and payable,
together with any accrued and unpaid interest thereon, on December 2, 2026.
 
INTEREST
 
  The Debentures bear interest at the annual rate of 6 3/4% per annum, payable
quarterly in arrears on March 1, June 1, September 1 and December 1 of each
year, commencing on March 1, 1997 (each, an "Interest Payment Date"), to the
person in whose name each Debenture is registered at the close of business on
the Business Day next preceding such Interest Payment Date, subject to certain
 
                                       43
<PAGE>
 
exceptions. It is anticipated that, until the liquidation, if any, of the
Issuer, each Debenture will be held in the name of the Property Trustee in
trust for the benefit of the holders of the Preferred Securities and the Common
Securities. The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months. In the event that any date
on which interest is payable on the Debentures is not a Business Day, then
payment of the interest 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). Accrued interest that is not paid on the
applicable Interest Payment Date will bear additional interest on the amount
thereof (to the extent permitted by law) at the stated rate per annum,
compounded quarterly. The term "interest" as used herein shall include
quarterly interest payments, interest on quarterly interest payments not paid
on the applicable Interest Payment Date and Additional Sums (as defined below),
as applicable.
 
GLOBAL SECURITIES
 
  If distributed to holders of the Preferred Securities in connection with the
involuntary or voluntary dissolution, winding-up or liquidation of the Issuer
as a result of the occurrence of a Special Event, the Debentures will be issued
in the same form as the Preferred Securities which such Debentures replace. Any
Global Certificate will be replaced by one or more global certificates (each a
"Global Security") registered in the name of the depository or its nominee.
Except under the limited circumstances described below, the Debentures
represented by the Global Security will not be exchangeable for, and will not
otherwise be issuable as, Debentures in definitive form. The Global Securities
described above may not be transferred except by the depository to a nominee of
the depository or by a nominee of the depository to the depository or another
nominee of the depository or to a successor depository or its nominee.
 
  The laws of some jurisdictions require that certain purchasers of securities
take physical delivery of such securities in definitive form. Such laws may
impair the ability to transfer beneficial interests in such a Global Security.
 
  Except as provided below, owners of beneficial interests in such a Global
Security will not be entitled to receive physical delivery of Debentures in
definitive form and will not be considered the holders thereof for any purpose
under the Indenture, and no Global Security representing Debentures shall be
exchangeable, except for another Global Security of like denomination and tenor
to be registered in the name of the depository or its nominee or to a successor
depository or its nominee. Accordingly, each beneficial owner of Preferred
Securities must rely on the procedures of DTC or if such person is not a
participant, on the procedures of the participant through which such person
owns its interest to exercise any rights of a holder under the Indenture.
 
  If Debentures are distributed to holders of Preferred Securities in
liquidation of such holders' interests in the Issuer and a Global Security is
issued, DTC will act as securities depository for the Debentures represented by
such Global Security. For a description of DTC and the specific terms of the
depository arrangements, see "Description of the Preferred Securities--Form,
Transfer, Exchange and Book-Entry Procedures." As of the date of this
Prospectus, the description therein of DTC's book-entry system and DTC's
practices as they relate to purchases, transfers, notices and payments with
respect to the Preferred Securities apply in all material respects to any debt
obligations represented by one or more Global Securities held by DTC. Host
Marriott may appoint a successor to DTC or any successor depository in the
event DTC or such depository is unable or unwilling to continue as a depository
for the Global Securities.
 
  None of Host Marriott, the Debenture Trustee, any Paying Agent or the
Securities Registrar have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of the Global Security representing such Debentures or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
                                       44
<PAGE>
 
  A Global Security shall be exchangeable for Debentures registered in the
names of persons other than DTC or its nominee only if (i) DTC notifies Host
Marriott that it is unwilling or unable to continue as a depository for such
Global Debenture and no successor depositary shall have been appointed by Host
Marriott within 90 days, or if at any time DTC ceases to be a clearing agency
registered under the Exchange Act at a time when DTC is required to be so
registered to act as such depository, (ii) Host Marriott in its sole discretion
determines that such Global Security shall be so exchangeable, or (iii) there
shall have occurred and be continuing an Event of Default with respect to such
Global Security. Any Global Security that is exchangeable pursuant to the
preceding sentence shall be exchangeable for definitive certificates registered
in such names as DTC shall direct. It is expected that such instructions will
be based upon directions received by DTC from its Participants with respect to
ownership of beneficial interests in such Global Security. In the event that
Debentures are issued in definitive form, such Debentures will be in
denominations of $50 and integral multiples thereof and may be transferred or
exchanged at the offices described in "--Payment and Paying Agents" below.
 
PAYMENT AND PAYING AGENTS
 
  Payments on Debentures represented by a Global Security will be made to DTC,
as the depositary for the Debentures. In the event Debentures are issued in
definitive form, principal of and premium, if any, and any interest on
Debentures will be payable, the transfer of the Debentures will be registrable,
and the Debentures will be exchangeable for Debentures of other denominations
of a like aggregate principal amount at the corporate office of the Debenture
Trustee in the City of New York or at the office of such Paying Agent or Paying
Agents as Host Marriott may designate, except that at the option of Host
Marriott payment of any interest may be made (i) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Securities
Register or (ii) by wire transfer to an account maintained by the Person
entitled thereto as specified in the Securities Register, provided that proper
transfer instructions have been received by the Regular Record Date. Payment of
any interest on Debentures will be made to the Person in whose name such
Debentures are registered at the close of business on the Regular Record Date
for such interest, except in the case of Defaulted Interest. The Regular Record
Date for the interest payable on any Interest Payment Date shall be the
fifteenth day (whether or not a Business Day) next preceding such Interest
Payment Date. Host Marriott may at any time designate additional Paying Agents
or rescind the designation of any Paying Agent.
 
  Any monies deposited with the Debenture Trustee or any Paying Agent, or then
held by Host Marriott in trust, for the payment of the principal of and
premium, if any, or interest on any Debentures and remaining unclaimed for two
years after such principal and premium, if any, or interest has become due and
payable shall, at the request of Host Marriott, be repaid to Host Marriott and
the holder of such Debentures shall thereafter look, as a general unsecured
creditor, only to Host Marriott for payment thereof.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD
 
  So long as no Event of Default under the Indenture has occurred and is
continuing, Host Marriott has the right under the Indenture to defer the
payment of interest (including any Liquidated Damages) on the Debentures at any
time or from time to time for a period not exceeding 20 consecutive quarters
with respect to each Extension Period, provided that no Extension Period may
extend beyond the stated maturity of the Debentures. At the end of such
Extension Period, Host Marriott must pay all interest then accrued and unpaid
(together with interest thereon at the stated annual rate, compounded
quarterly, to the extent permitted by applicable law). During an Extension
Period, interest will continue to accrue and holders of Debentures (or holders
of Preferred Securities while the Preferred Securities are outstanding) will be
required to accrue interest income for United States Federal income tax
purposes. See "Certain Federal Income Tax Consequences--Original Issue
Discount."
 
 
                                       45
<PAGE>
 
  During any such Extension Period, Host Marriott may not, and may not cause
any subsidiary to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any
of Host Marriott's capital stock or (ii) make any payment of principal,
interest or premium, if any, on or repay, repurchase or redeem any debt
securities (including guarantees of indebtedness for money borrowed) of Host
Marriott that rank pari passu with or junior to the Debentures (other than (a)
any dividend, redemption, liquidation, interest, principal or guarantee payment
by Host Marriott where the payment is made by way of securities (including
capital stock) that rank pari passu with or junior to the securities on which
such dividend, redemption, interest, principal or guarantee payment is being
made, (b) redemptions or purchases of any Rights pursuant to Host Marriott's
Rights Agreement, or any successor to such Rights Agreement, and the
declaration of a dividend of such Rights or the issuance of preferred stock
under such plans in the future, (c) payments under the Guarantee, (d) purchases
of Host Marriott Common Stock related to the issuance of Host Marriott Common
Stock under any of Host Marriott's benefit plans for its directors, officers or
employees, (e) as a result of a reclassification of Host Marriott's capital
stock or the exchange or conversion of one series or class of Host Marriott's
capital stock for another series or class of Host Marriott's capital stock, and
(f) the purchase of fractional interests in shares of Host Marriott's capital
stock pursuant to the conversion or exchange provisions of such capital stock
or the security being converted or exchanged). Prior to the termination of any
such Extension Period, Host Marriott may further extend the interest payment
period, provided that no Extension Period may exceed 20 consecutive quarters or
extend beyond the stated maturity of the Debentures. Upon the termination of
any such Extension Period and the payment of all amounts then due on any
Interest Payment Date, Host Marriott may elect to begin a new Extension Period
subject to the above requirements. No interest shall be due and payable during
an Extension Period, except at the end thereof. Host Marriott shall give the
Property Trustee, the Administrative Trustees and the Debenture Trustee notice
of its election to begin any Extension Period at least one Business Day prior
to the earlier of (i) the record date for the date Distributions on the
Preferred Securities (or, if no Preferred Securities are outstanding, for the
date interest on the Debentures) would have been payable except for the
election to begin such Extension Period and (ii) the date the Property Trustee
is (or, if no Preferred Securities are outstanding, the Debenture Trustee is)
required to give notice to the NYSE or other applicable self-regulatory
organization or to holders of such Preferred Securities (or, if no Preferred
Securities are outstanding, to the holders of such Debentures) of such record
date. The Debenture Trustee and the Property Trustee shall give notice of Host
Marriott's election to begin an Extension Period to the holders of the
Debentures and the Preferred Securities, respectively.
 
MANDATORY REDEMPTION
 
  Upon repayment at maturity or as a result of acceleration upon the occurrence
of a Debenture Event of Default, Host Marriott will redeem the Debentures, in
whole but not in part, at a redemption price equal to 100% of the principal
amount thereof, together with any accrued and unpaid interest thereon. Any
payment pursuant to this provision shall be made prior to 12:00 noon, New York
City time, on the date of such repayment or acceleration or at such other time
on such earlier date as the parties thereto shall agree. The Debentures are not
entitled to the benefit of any sinking fund or, except as set forth above or as
a result of acceleration, any other provision for mandatory prepayment.
 
                                       46

OPTIONAL REDEMPTION
 
  On and after December 2, 1999, and subject to the next succeeding sentence,
Host Marriott has the right, at any time and from time to time, to redeem the
Debentures, in whole or in part, upon notice given as provided below, during
the twelve month periods beginning on December 2 in each of the following years
and at the indicated redemption prices (expressed as a percentage of the
principal amount of the Debentures being redeemed), together with any accrued
but unpaid interest on the portion being redeemed.

  The principal amount of the Debentures so redeemed may not, however, exceed
the amount of the proceeds derived, directly or indirectly, by Host Marriott or
its subsidiaries from the issuance and sale of common stock within two years
preceding the date fixed for redemption. For so long as the Issuer is the
holder of all the outstanding Debentures, the proceeds of any such redemption
will be used by the Issuer to redeem Preferred Securities and Common Securities
in accordance with their terms. Host Marriott may not redeem the Debentures in
part unless all accrued and unpaid interest has been paid in full on all
outstanding Debentures. See "Description of the Preferred Securities--Optional
Redemption."
 
  Host Marriott also has the right to redeem the Debentures at any time after
December 2, 1999 upon the occurrence of a Tax Event as described in
"Description of the Preferred Securities--Special Event Exchange or
Redemption."
 
  If at any time following the Conversion Expiration Date, less than 5% of the
original aggregate principal amount of the Debentures remains outstanding, such
Debentures shall be redeemable at the option of Host Marriott, in whole but not
in part, at a redemption price equal to the principal amount thereof, plus any
accrued and unpaid interest.
 
REDEMPTION PROCEDURES
 
  Notices of any redemption of the Debentures and the procedures for such
redemption shall be as provided with respect to the Preferred Securities under
"Description of the Preferred Securities-- Redemption Procedures." Notice of
any redemption will be mailed at least 30 days but not more than 60 days before
the redemption date to each holder of Debentures to be redeemed at its
registered address. Unless Host Marriott defaults in payment of the redemption
price, on and after the redemption date interest ceases to accrue on such
Debentures or portions thereof called for redemption.
 
DISTRIBUTION OF DEBENTURES
 
  At any time, Host Marriott has the right to terminate the Issuer and cause
the Debentures to be distributed to the holders of the Preferred Securities in
liquidation of the Issuer after satisfaction of liabilities to creditors of the
Issuer as provided by applicable law. If distributed to holders of Preferred
Securities in liquidation, the Debentures will initially be issued in the form
of one or more global securities and DTC, or any successor depositary for the
Preferred Securities, will act as depositary for the Debentures. It is
anticipated that the depositary arrangements for the Debentures would be
substantially identical to those in effect for the Preferred Securities. There
can be no assurance as to the market price of any Debentures that may be
distributed to the holders of Preferred Securities. For a description of DTC
and the terms of the depositary matters, see "Description of the Preferred
Securities--Form, Transfer, Exchange and Book-Entry Procedures."
 
                                       47
<PAGE>
 
CONVERSION OF THE DEBENTURES
 
  The Debentures are convertible at the option of the holders of the Debentures
into Host Marriott Common Stock, at any time prior to redemption, maturity or
the Conversion Expiration Date, initially at the rate of 2.6876 shares of Host
Marriott Common Stock for each $50 in principal amount of Debentures
(equivalent to a conversion price of $18.604 per share of Host Marriott Common
Stock), subject to the conversion price adjustments described under
"Description of the Preferred Securities-- Conversion Rights." The Issuer
covenants for so long as the Preferred Securities are outstanding not to
convert Debentures except pursuant to a notice of conversion delivered to the
Conversion Agent by a holder of Preferred Securities. Upon surrender of such
Preferred Securities to the Conversion Agent for conversion, the Issuer will
distribute the commensurate principal amount of the Debentures to the
Conversion Agent on behalf of the holder of every Preferred Security so
converted, whereupon the Conversion Agent will convert such Debentures into
Host Marriott Common Stock on behalf of such holder. Host Marriott's delivery
to the holders of the Debentures (through the Conversion Agent) of the fixed
number of shares of Host Marriott Common Stock into which the Debentures are
convertible (together with the cash payment, if any, in lieu of fractional
shares) will be deemed to satisfy Host Marriott's obligation to pay the
principal amount of the Debentures, and the accrued and unpaid interest
attributable to the period from the last date to which interest has been paid
or duly provided for.
 
EXPIRATION OF CONVERSION RIGHTS
 
  The conversion rights of any Debentures held by the Issuer expire upon the
expiration of the conversion rights of the Preferred Securities on the terms
described above under "Description of the Preferred Securities--Expiration of
Conversion Rights." In the case of any Debentures that have been exchanged for
Preferred Securities under the conditions described under "Description of the
Preferred Securities--Special Event Exchange or Redemption," on and after
December 2, 1999 Host Marriott may, at its option, cause the conversion rights
of holders of such Debentures to expire. Host Marriott may exercise this option
only if for 20 trading days within any period of 30 consecutive trading days,
including the last trading day of such period, the Current Market Price of Host
Marriott Common Stock exceeds 120% of the conversion price of the Debentures,
subject to adjustment in certain circumstances. In order to exercise its
conversion expiration option, Host Marriott must issue a press release for
publication on the Dow Jones News Service announcing the Conversion Expiration
Date prior to the opening of business on the second trading day after any
period in which the condition in the preceding sentence has been met, but in no
event prior to December 2, 1999. The press release shall announce the
Conversion Expiration Date and provide the current conversion price and Current
Market Price of Host Marriott Common Stock, in each case as of the close of
business on the trading day next preceding the date of the press release.
 
  Notice of the expiration of conversion rights will be given by first-class
mail to the holders of the Debentures not more than four Business Days after
Host Marriott issues the press release. The Conversion Expiration Date will be
a date selected by Host Marriott not less than 30 nor more than 60 days after
the date on which Host Marriott issues the press release announcing its
intention to terminate the conversion rights of Debenture holders. In the event
that Host Marriott does not exercise its conversion expiration option, the
Conversion Expiration Date with respect to the Debentures will be two Business
Days preceding the date set for mandatory redemption of the Debentures.
 
MODIFICATION OF INDENTURE
 
  From time to time, Host Marriott and the Debenture Trustee may, without the
consent of the holders of Debentures, amend, waive or supplement the Indenture
for specified purposes, including, among other things, curing ambiguities,
defects or inconsistencies (provided that any such action does not materially
adversely affect the interest of the holders of the Debentures, or the holders
of the Preferred Securities so long as they remain outstanding) and qualifying,
or maintaining the qualification
 
                                       48
<PAGE>
 
of, the Indenture under the Trust Indenture Act. The Indenture contains
provisions permitting Host Marriott and the Debenture Trustee, with the consent
of the holders of not less than a majority in principal amount of the
outstanding Debentures, to modify the Indenture in a manner affecting the
rights of the holders of the Debentures; provided that no such modification
may, without the consent of the holder of each outstanding Debentures so
affected, (i) change the stated maturity of the Debentures, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon (other than deferrals of the payments of interest as described
under "--Option to Extend Interest Payment Period") or impair any right to
institute suit for the enforcement of any such payment, or adversely affect the
subordination provisions of the Indenture or any right to convert any
Debentures or (ii) reduce the percentage of principal amount of Debentures, the
holders of which are required to consent to any such modification of the
Indenture, provided that, so long as any of the Preferred Securities remain
outstanding, no such modification may be made that adversely affects the
holders of such Preferred Securities in any material respect, and no
termination of the Indenture may occur, and no waiver of any Debenture Event of
Default or compliance with any covenant under the Indenture may be effective,
without the prior consent of the holders of at least a majority in aggregate
liquidation amount of the Preferred Securities then outstanding unless and
until the principal of the Debentures and all accrued and unpaid interest
thereon has been paid in full.
 
DEBENTURE EVENTS OF DEFAULT
 
  The Indenture provides that any one or more of the following described events
that has occurred and is continuing constitutes a "Debenture Event of Default"
with respect to such Debentures:
 
    (i) failure for 30 days to pay any interest on the Debentures, when due
  (subject to the deferral of any due date in the case of an Extension
  Period); or
 
    (ii) failure to pay any principal or premium, if any, on the Debentures
  when due whether at maturity, upon redemption by declaration or otherwise;
  or
 
    (iii) failure by Host Marriott to deliver shares of Host Marriott Common
  Stock upon an appropriate election by holders of Debentures to convert such
  Debentures; or
 
    (iv) failure to observe or perform in any material respect certain other
  covenants contained in the Indenture for 90 days after written notice to
  Host Marriott from the Debenture Trustee or to the Debenture Trustee and
  Host Marriott from the holders of at least 25% in aggregate outstanding
  principal amount of such Debentures; or
 
    (v) certain events in bankruptcy, insolvency or reorganization of Host
  Marriott.
 
  The holders of a majority in aggregate outstanding principal amount of the
Debentures have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Debenture Trustee. The Debenture
Trustee or the holders of not less than 25% in aggregate principal amount of
the Debentures then outstanding may declare the principal due and payable
immediately upon a Debenture Event of Default, and, should the Debenture
Trustee or the holders of the Debentures fail to make such declaration, the
holders of at least 25% in aggregate liquidation amount of the Preferred
Securities then outstanding shall have such right. The holders of a majority in
aggregate outstanding principal amount of the Debentures may annul and rescind
such declaration if the default (other than the non-payment of the principal of
the Debentures which has become due solely by such acceleration) 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 Debenture
Trustee and, should the holders of the Debentures fail to annul and rescind
such declaration, the holders of a majority in aggregate liquidation amount of
the Preferred Securities then outstanding shall have such right.
 
  The holders of a majority in aggregate outstanding principal amount of the
Debentures affected thereby may, on behalf of the holders of all the
Debentures, waive any past default, except a default
 
                                       49
<PAGE>
 
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 Debenture 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 and, should the holders of the Debentures fail to annul
such declaration and waive such default, the holders of a majority in aggregate
liquidation amount of the Preferred Securities shall have such right. Host
Marriott is required to file annually with the Debenture Trustee a certificate
as to whether or not Host Marriott is in compliance with all the conditions and
covenants applicable to it under the Indenture.
 
  In case a Debenture Event of Default shall occur and be continuing as to the
Debentures, the Property Trustee has the right to declare the principal of and
the interest on the Debentures and any other amounts payable under the
Indenture to be forthwith due and payable and to enforce its other rights as a
creditor with respect to the Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
  If a Debenture Event of Default has occurred and is continuing and such event
is attributable to the failure of Host Marriott to pay interest or principal on
the Debentures on the date such interest or principal is otherwise payable, a
holder of Preferred Securities may institute a Direct Action for payment after
the respective due date specified in the Debentures. Host Marriott may not
amend the Indenture to remove the foregoing right to bring a Direct Action
without the prior written consent of the holders of all of the Preferred
Securities. Notwithstanding any payment made to such holder of Preferred
Securities by Host Marriott in connection with a Direct Action, Host Marriott
shall remain obligated to pay the principal of or interest on the Debentures
held by the Issuer or the Property Trustee and Host Marriott shall be
subrogated to the rights of the holder of such Preferred Securities with
respect to payments on the Preferred Securities to the extent of any payments
made by Host Marriott to such holder in any Direct Action.
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
  The Indenture provides that Host Marriott shall not consolidate with or merge
into any other Person or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, and no Person shall consolidate
with or merge into Host Marriott or convey, transfer or lease its properties
and assets substantially or as an entirety to Host Marriott, unless (i) in case
Host Marriott consolidates with or merges into another Person or conveys,
transfers or leases its properties and assets substantially as an entirety to
any Person, the successor Person is organized under the laws of the United
States or any state or the District of Columbia, and such successor Person
expressly assumes Host Marriott's obligations on the Debentures; (ii)
immediately after giving effect thereto, no Debenture Event of Default, and no
event which, after notice or lapse of time or both, would become a Debenture
Event of Default, shall have happened and be continuing; (iii) in the case of
the Debentures, such transaction is permitted under the Trust Agreement and
Guarantee and does not give rise to any breach or violation of the Trust
Agreement or Guarantee; and (iv) certain other conditions as prescribed in the
Indenture are met.
 
  The general provisions of the Indenture do not afford holders of the
Debentures protection in the event of a highly leveraged or other transaction
involving Host Marriott that may adversely affect holders of the Debentures.
 
EXPENSES OF ISSUER
 
  Pursuant to the Indenture, Host Marriott will pay all of the costs, expenses
or liabilities of the Issuer, other than obligations of the Issuer to pay to
the holders of any Preferred Securities or Common Securities the amounts due
such holders pursuant to the terms of the Preferred Securities or Common
Securities.
 
                                       50
<PAGE>
 
SATISFACTION AND DISCHARGE
 
  The Indenture provides that when, among other things, all Debentures not
previously delivered to the Debenture Trustee for cancellation (i) have become
due and payable or (ii) will become due and payable at their stated maturity
within one year, and Host Marriott deposits or causes to be deposited with the
Debenture Trustee trust funds, in trust, for the purpose and in an amount in
the currency or currencies in which the Debentures are payable sufficient to
pay and discharge the entire indebtedness on the Debentures not previously
delivered to the Debenture Trustee for cancellation, for the principal and
premium, if any, and interest to the date of the deposit or to the stated
maturity, as the case may be, then the Indenture will cease to be of further
effect (except as to Host Marriott's obligations to pay all other sums due
pursuant to the Indenture and to provide the officers' certificates and
opinions of counsel described therein), and Host Marriott will be deemed to
have satisfied and discharged the Indenture.
 
SUBORDINATION
 
  In the Indenture, Host Marriott has covenanted and agreed that any Debentures
issued thereunder is subordinate and junior in right of payment to all Senior
Debt of Host Marriott whether now existing or hereinafter incurred. Upon any
payment or distribution of assets to creditors upon any liquidation,
dissolution, winding-up, reorganization, assignment for the benefit of
creditors, marshaling of assets or any bankruptcy, insolvency, debt
restructuring or similar proceedings in connection with any insolvency or
bankruptcy proceeding of Host Marriott, the holders of Senior Debt are first
entitled to receive payment in full of principal of and premium, if any, and
interest, if any, on such Senior Debt before the Property Trustee, on behalf of
the holders of the Debentures, are entitled to receive or retain any payment in
respect of the principal of and premium, if any, or interest, if any, on the
Debentures.
 
  In the event of the acceleration of the maturity of any Debentures, the
holders of all Senior Debt outstanding at the time of such acceleration are
first entitled to receive payment in full of all amounts due thereon (including
any amounts due upon acceleration) before the holders of Debentures are
entitled to receive or retain any payment in respect of the principal of or
premium, if any, or interest, if any, on the Debentures.
 
  No payments on account of principal (or premium, if any) or interest, if any,
in respect of the Debentures may be made if there shall have occurred and be
continuing a default in any payment with respect to Senior Debt, or an event of
default with respect to any Senior Debt resulting in the acceleration of the
maturity thereof, or if any judicial proceeding shall be pending with respect
to any such default.
 
  "Debt" means, with respect to any Person, whether recourse is to all or a
portion of the assets of such Person and whether or not contingent, (i) every
obligation of such Person for money borrowed; (ii) every obligation of such
Person evidenced by bonds, debentures, notes or other similar instruments,
including obligations incurred in connection with the acquisition of property,
assets or businesses; (iii) every reimbursement obligation of such Person with
respect to letters of credit, bankers' acceptances or similar facilities issued
for the account of such Person; (iv) every obligation of such Person issued or
assumed as the deferred purchase price of property or services (but excluding
trade accounts payable or accrued liabilities arising in the ordinary course of
business); (v) every capital lease obligation of such Person; and (vi) every
obligation of the type referred to in clauses (i) through (v) of another Person
and all dividends of another person the payment of which, in either case, such
Person has guaranteed or for which such Person is responsible or liable,
directly or indirectly, as obligor or otherwise.
 
  "Senior Debt" means the principal of (and premium, if any) and interest, if
any (including interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to Host Marriott whether or not such
claim for post-petition interest is allowed in such proceeding), on Debt of
Host
 
                                       51
<PAGE>
 
Marriott, whether incurred on or prior to the date of the Indenture or
thereafter incurred, unless, in the instrument creating or evidencing the same
or pursuant to which the same is outstanding, it is provided that such
obligations are not superior in right of payment to the Debentures or to other
Debt which is pari passu with, or subordinated to, the Debentures; provided,
however, that Senior Debt does not include:
 
    (i) any Debt of Host Marriott which, when incurred and without respect to
  any election under Section 1111 (b) of the Bankruptcy Code, was without
  recourse to Host Marriott,
 
    (ii) any Debt of Host Marriott to any of its subsidiaries,
 
    (iii) Debt to any employee of Host Marriott,
 
    (iv) any liability for taxes, and
 
    (v) Debt or other monetary obligations to trade creditors or assumed by
  Host Marriott or any of its subsidiaries in the ordinary course of business
  in connection with the obtaining of goods, materials or services.
 
  The Indenture places no limitation on the amount of additional Senior Debt
that may be incurred by Host Marriott.
 
GOVERNING LAW
 
  The Indenture and the Debentures are governed by and construed in accordance
with the laws of the State of New York.
 
INFORMATION CONCERNING THE DEBENTURE TRUSTEE
 
  The Debenture Trustee is under no obligation to exercise any of the powers
vested in it by the Indenture at the request of any holder of Debentures,
unless offered reasonable indemnity by such holder against the costs, expenses
and liabilities which might be incurred thereby. The Debenture Trustee is not
required to expend or risk its own funds or otherwise incur personal financial
liability in the performance of its duties if the Debenture Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.
 
  RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE DEBENTURE AND THE GUARANTEE
 
FULL AND UNCONDITIONAL GUARANTEE
 
  Payments of Distributions and other amounts due on the Preferred Securities
(to the extent the Issuer has funds available for the payment of such
Distributions) are irrevocably guaranteed by Host Marriott as and to the extent
set forth under "Description of the Guarantee." Taken together, Host Marriott's
obligations under the Debentures, the Indenture, the Trust Agreement and the
Guarantee provide, in the aggregate, a full, irrevocable and unconditional
guarantee of payments of Distributions and other amounts due on the Preferred
Securities. No single document standing alone or operating in conjunction with
fewer than all of the other documents constitutes such guarantee. It is only
the combined operation of these documents that has the effect of providing a
full, irrevocable and unconditional guarantee of the Issuer's obligations under
the Preferred Securities. If and to the extent that Host Marriott does not make
payments on the Debentures, the Issuer will not pay Distributions or other
amounts due on the Preferred Securities. The Guarantee does not cover payment
of Distributions when the Issuer does not have sufficient funds to pay such
Distributions. In such event, a holder of Preferred Securities may institute a
Direct Action directly against Host Marriott to enforce payment of such
Distributions to such holder after the respective due dates. The obligations of
Host Marriott under the Guarantee are subordinate and junior in right of
payment to all other liabilities of Host Marriott; and pari passu with any
guarantee now or hereafter entered into by Host Marriott in respect of any
preferred or preference stock of any affiliate of Host Marriott.

SUFFICIENCY OF PAYMENTS
 
  As long as payments of interest and other payments are made when due on the
Debentures, such payments will be sufficient to cover Distributions and other
payments due on the Preferred Securities, primarily because (i) the aggregate
principal amount of the Debentures will be equal to the sum of the aggregate
stated liquidation amount of the Preferred Securities and Common Securities;
(ii) the interest rate and interest and other payment dates on the Debentures
will match the Distribution rate and Distribution and other payment dates for
the Preferred Securities; (iii) Host Marriott shall pay for all and any costs,
expenses and liabilities of the Issuer except the Issuer's obligations to
holders of the Preferred Securities under such Preferred Securities; and (iv)
the Trust Agreement further provides that the Issuer will not engage in any
activity that is not consistent with the limited purposes of the Issuer.
 
  Notwithstanding anything to the contrary in the Indenture, Host Marriott has
the right to set-off any payment it is otherwise required to make thereunder
with and to the extent Host Marriott has theretofore made, or is concurrently
on the date of such payment making, a payment under the Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES
 
  A holder of any Preferred Securities may institute a legal proceeding
directly against Host Marriott to enforce its rights under the Guarantee
without first instituting a legal proceeding against the Guarantee Trustee, the
Issuer or any other person or entity.
 
  A default or event of default under any Senior Debt of Host Marriott will not
constitute a default under the Indenture or a Debenture Event of Default.
However, in the event of payment defaults under, or acceleration of, Senior
Debt of Host Marriott, the subordination provisions of the Indenture provide
that no payments may be made in respect of the Debentures until such Senior
Debt has been paid in full or any payment default thereunder has been cured or
waived. Failure to make required payments on the Debentures would constitute a
Debenture Event of Default.
 
LIMITED PURPOSE OF ISSUER
 
  The Preferred Securities evidence a beneficial interest in the Issuer, and
the Issuer exists for the sole purpose of issuing the Preferred Securities and
Common Securities and investing the proceeds thereof in the Debentures. A
principal difference between the rights of a holder of Preferred Securities and
a holder of Debentures is that a holder of Debentures is entitled to receive
from Host Marriott the principal amount of and interest accrued on Debentures
held, while a holder of Preferred Securities is entitled to receive
Distributions from the Issuer (or from Host Marriott under the applicable
Guarantee) if and to the extent the Issuer has funds available for the payment
of such Distributions.
 
RIGHTS UPON TERMINATION
 
  Upon any voluntary or involuntary termination, winding-up or liquidation of
the Issuer involving the liquidation of the Debentures, the holders of the
Preferred Securities will be entitled to receive, out of assets held by the
Issuer, the Liquidation Distribution in cash. See "Description of the Preferred
Securities--Liquidation Distribution Upon Termination." Upon any voluntary or
involuntary liquidation or bankruptcy of Host Marriott, the Property Trustee,
as holder of the Debentures, would be a subordinated creditor of Host Marriott,
subordinated in right of payment to all Senior Debt, but entitled to receive
payment in full of principal and interest before any stockholders of Host
Marriott receive payments or distributions. Since Host Marriott is the
guarantor under the Guarantee and has agreed to pay for all costs, expenses and
liabilities of the Issuer (other than the Issuer's obligations to the holders
of the Preferred Securities), the positions of a holder of such Preferred
Securities and a holder
 
                                       53
<PAGE>
 
of such Debentures relative to other creditors and to stockholders of Host
Marriott in the event of liquidation or bankruptcy of Host Marriott would be
substantially the same.
 
                   DESCRIPTION OF HOST MARRIOTT CAPITAL STOCK
 
  The following description of Host Marriott's capital stock is a summary and
is subject in all respects to applicable Delaware law and to the provisions of
the Company's Restated Certificate of Incorporation and shareholder's rights
plan.
 
GENERAL
 
  Host Marriott's Restated Certificate of Incorporation (the "Company
Certificate") authorizes the issuance of a total of 301 million shares of all
classes of stock, of which one million may be shares of preferred stock,
without par value, and 300 million may be shares of Common Stock. At January 3,
1997, approximately 202.1 million shares of Common Stock were outstanding. The
Company Certificate provides that the Board is authorized to provide for the
issuance of shares of preferred stock, from time to time, in one or more
series, and to fix any voting powers, full or limited or none, and the
designations, preferences and relative, participating, optional or other
special rights, applicable to the shares to be included in any such series and
any qualifications, limitations or restrictions thereon.
 
COMMON STOCK
 
 VOTING RIGHTS
 
  Each holder of Common Stock is entitled to one vote for each share registered
in his name on the books of Host Marriott on all matters submitted to a vote of
shareholders. Except as otherwise provided by law, the holders of Common Stock
vote as one class. The shares of Common Stock do not have cumulative voting
rights. As a result, subject to the voting rights, if any, of the holders of
any shares of Host Marriott's preferred stock which may at the time be
outstanding, the holders of Common Stock entitled to exercise more than 50% of
the voting rights in an election of directors will be able to elect 100% of the
directors to be elected if they choose to do so. In such event, the holders of
the remaining Common Stock voting for the election of directors will not be
able to elect any persons to the Board. The Company Certificate provides that
the Board is classified into three classes, each serving a three-year term,
with one class to be elected in each of three consecutive years.
 
 DIVIDEND RIGHTS
 
  Subject to the rights of the holders of any shares of the Company's preferred
stock which may at the time be outstanding, holders of Common Stock are
entitled to such dividends as the Board of Directors may declare out of funds
legally available therefor. Host Marriott intends to retain future earnings for
use in its business and does not currently intend to pay regular cash
dividends. In addition, the MI Line of Credit contains restrictions on the
payment of dividends on the Common Stock. See "Dividend Policy."
 
 LIQUIDATION RIGHTS AND OTHER PROVISIONS
 
  Subject to the prior rights of creditors and the holders of any of Host
Marriott's preferred stock which may be outstanding from time to time, the
holders of Common Stock are entitled in the event of liquidation, dissolution
or winding up to share pro rata in the distribution of all remaining assets.
The Common Stock is not liable for any calls or assessments and is not
convertible into any other securities. The Company Certificate provides that
the private property of the shareholders shall not be subject to the payment of
corporate debts. There are no redemption or sinking fund provisions
 
                                       54
<PAGE>
 
applicable to the Common Stock, and the Company Certificate provides that there
shall be no preemptive rights.
 
  The transfer agent and registrar for the Common Stock is First Chicago Trust
of New York.
 
RIGHTS AND JUNIOR PREFERRED STOCK
 
  Host Marriott has adopted a shareholder rights plan as set forth in a Rights
Agreement dated February 3, 1989, as amended, between the Company and the Bank
of New York, as rights agent (the "Rights Agreement"). The following is a
summary of the terms of the Rights Agreement.
 
 RIGHTS
 
  Following the occurrence of certain events (the "Occurrence Date") and except
as described below, each right (a "Right," and, collectively, the "Rights")
will entitle the registered holder thereof to purchase from the Company one
one-thousandth of a share (a "Unit") of Host Marriott's Series A Junior
Participating Preferred Stock ("Junior Preferred Stock") at a price (the
"Purchase Price") of $150 per Unit, subject to adjustment. The Rights are not
exercisable until the Occurrence Date. The Rights expire on the tenth
anniversary of the adoption of the Rights Agreement, unless exercised in
connection with a transaction of the type described below or unless earlier
redeemed by Host Marriott.
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a Host Marriott shareholder, including, without limitation, the right to
vote or to receive dividends.
 
  Initially, ownership of the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate certificates
representing the Rights (the "Rights Certificates") will be distributed. Until
the Occurrence Date (or earlier redemption or expiration of the Rights), the
Rights will be transferable only with the Common Stock, and the surrender or
transfer of any certificate of Common Stock will also constitute the transfer
of the Rights associated with the Common Stock represented by such certificate.
The Rights will separate from the Common Stock and an Occurrence Date will
occur upon the earlier of (i) 10 days following the date (a "Stock Acquisition
Date") of a public announcement that a person or group of affiliates or
associated persons (an "Acquiring Person") has acquired, or obtained the right
to acquire, beneficial ownership of 20% or more of the outstanding Common Stock
or (ii) 10 business days following the commencement of or announcement of an
intention to make a tender offer or exchange offer, the consummation of which
would result in the Acquiring Person becoming the beneficial owner of 30% or
more of such outstanding Common Stock (such date being called the Occurrence
Date).
 
  For purposes of the Rights Agreement, a person shall not be deemed to
beneficially own "Exempt Shares" which include (i) shares of Common Stock
acquired by such person by gift, bequest and certain other transfers, which
shares were Exempt Shares immediately prior to such transfer and were held by
such person continuously thereafter and (ii) shares acquired by such person in
connection with certain distributions of Common Stock with respect to Exempt
Shares which were held by such person continuously thereafter. In connection
with the Marriott International Distribution, the Board amended the Rights
Agreement to provide that the shares of Common Stock acquired by Marriott
International upon exercise of the Marriott International Purchase Right will
be deemed "Exempt Shares" under the Rights Agreement, such that the exercise of
such right by Marriott International will not cause Marriott International to
be deemed an "Acquiring Person" under the Rights Agreement and thus trigger a
distribution of the Rights. See "Relationship Between the Company and Marriott
International--Marriott International Purchase Right."
 
  As soon as practicable following an Occurrence Date, Rights Certificates will
be mailed to holders of record of Common Stock as of the close of business on
the Occurrence Date. After such time, such
 
                                       55
<PAGE>
 
separate Rights Certificates alone will evidence the Rights and could trade
independently from the Common Stock.
 
  In the event (i) Host Marriott is the surviving corporation in a merger with
an Acquiring Person and the Common Stock is not changed or exchanged, or (ii)
an Acquiring Person becomes the beneficial owner of 30% or more of the then
outstanding shares of Common Stock (except pursuant to an offer for all
outstanding shares of Common Stock which the Board determines to be fair to and
otherwise in the best interests of the Company and its shareholders), each
holder of a Right will, in lieu of the right to receive one one-thousandth of a
share of Junior Preferred Stock, thereafter have the right to receive, upon
exercise, Common Stock (or, in certain circumstances, cash, property or other
securities of Host Marriott) having a value equal to two times the exercise
price of the Right. Notwithstanding any of the foregoing, following the
occurrence of any of the events set forth in this paragraph, all Rights that
are (or, under certain circumstances specified in the Rights Agreement, were)
beneficially owned by any Acquiring Person will be null and void. However, the
Rights are not exercisable following the occurrence of either of the events set
forth above until such time as the Rights are no longer redeemable by Host
Marriott as set forth below.
 
  For example, at an exercise price of $150 per Right, each Right not owned by
an Acquiring Person (or by certain related parties) following an event set
forth in the preceding paragraph would entitle its holder to purchase $300
worth of Common Stock (or other consideration, as noted above) for $150.
Assuming that the Common Stock had a per share value of $30 at such time, the
holder of each valid Right would be entitled to purchase 10 shares of Common
Stock for $150.
 
  In the event that, at any time following the Stock Acquisition Date, (i) Host
Marriott is acquired in a merger or other business combination transaction in
which Host Marriott is not the surviving corporation (other than a merger
described in the second preceding paragraph or a merger which follows an offer
described in the second preceding paragraph), or (ii) 50% or more of Host
Marriott's assets or earning power is sold or transferred, each holder of a
Right (except Rights which previously have been voided as set forth above)
shall thereafter have the right to receive, upon exercise, common stock of the
acquiring company having a value equal to two times the exercise price of the
Right.
 
  In general, the Board may redeem the Rights in whole, but not in part, at any
time until 10 days following the Stock Acquisition Date, at a price of $.01 per
Right. After the redemption period has expired, the Company's right of
redemption may be reinstated if an Acquiring Person reduces its beneficial
ownership to 10% or less of the outstanding shares of Common Stock in a
transaction or series of transactions not involving the Company. Immediately
upon the action of the Board ordering redemption of the Rights, the Rights will
terminate and the only right of the holders of Rights will be to receive the
$.01 per Right redemption price.
 
  The purchase price payable, and the number of shares of Junior Preferred
Stock or other securities or property issuable upon exercise of the Rights are
subject to adjustment upon the occurrence of certain events with respect to the
Company, including stock dividends, subdivisions, combinations,
reclassifications, rights or warrants offerings of Junior Preferred Stock at
less than the then current market price and certain distributions of property
or evidences of indebtedness of Host Marriott to holders of Junior Preferred
Stock, all as set forth in the Rights Agreement.
 
  The Rights have certain antitakeover effects. The Rights may cause
substantial dilution to a person or group that attempts to acquire Host
Marriott on terms not approved by the Board, except pursuant to an offer
conditioned on a substantial number of Rights being acquired. The Rights should
not interfere with any merger or other business combination approved by the
Board since the Rights may be redeemed by Host Marriott as set forth above. See
"Purposes and Antitakeover Effects of Certain Provisions of Host Marriott
Certificate and Bylaws and the Marriott International Purchase Right."

 JUNIOR PREFERRED STOCK
 
  In connection with the Rights Agreement, 300,000 shares of Junior Preferred
Stock are authorized and reserved for issuance by the Board. No shares of
Junior Preferred Stock are currently outstanding. The material terms of the
Junior Preferred Stock are summarized herein; however, such summary is subject
to the terms of the Company Certificate and the certificate of designation
relating to the Junior Preferred Stock (the "Junior Preferred Stock Certificate
of Designation").
 
  Subject to the prior payment of cumulative dividends on any class of
preferred stock ranking senior to the Junior Preferred Stock, a holder of
Junior Preferred Stock will be entitled to cumulative dividends out of funds
legally available therefor, when, as and if declared by the Board, at a
quarterly rate per share of Junior Preferred Stock equal to the greater of (a)
$10.00 or (b) 1000 times (subject to adjustment upon certain dilutive events)
the aggregate per share amount of all cash dividends and 1000 times (subject to
adjustment upon certain dilutive events) the aggregate per share amount
(payable in kind) of all noncash dividends or other distributions (other than
dividends payable in Common Stock or a sub-division of the outstanding shares
of Common Stock) declared on Common Stock, since the immediately preceding
quarterly dividend payment date for the Junior Preferred Stock (or since the
date of issuance of the Junior Preferred Stock if no such dividend payment date
has occurred).
 
  A holder of Junior Preferred Stock will be entitled to 1000 votes (subject to
adjustment upon certain dilutive events) per share of Junior Preferred Stock on
all matters submitted to a vote of Host Marriott shareholders. Such holders
will vote together with the holders of the Common Stock as a single class on
all matters submitted to a vote of Host Marriott shareholders.
 
  In the event of a merger or consolidation of Host Marriott which results in
Common Stock being exchanged or changed for other stock, securities, cash
and/or other property, the shares of Junior Preferred Stock shall similarly be
exchanged or changed in an amount per share equal to 1000 times (subject to
adjustment upon certain dilutive events) the aggregate amount of stock,
securities, cash and/or other property, as the case may be, into which each
share of Common Stock has been exchanged or changed.
 
  In the event of liquidation, dissolution or winding up of Host Marriott, a
holder of Junior Preferred Stock will be entitled to receive $1000 per share,
plus accrued and unpaid dividends and distributions thereon, before any
distribution may be made to holders of shares of stock of Host Marriott ranking
junior to the Junior Preferred Stock, and the holders of Junior Preferred Stock
are entitled to receive an aggregate amount per share equal to 1000 times
(subject to adjustment upon certain dilutive events) the aggregate amount to be
distributed per share to holders of Common Stock.
 
  In the event that dividends on the Junior Preferred Stock are in arrears in
an amount equal to six quarterly dividends thereon, all holders of Junior
Preferred Stock, voting separately as a class with the holders of any other
series of preferred stock of Host Marriott with dividends in arrears, will be
entitled to elect two directors pursuant to provisions of the Company
Certificate. Such right to elect two additional directors shall continue at
each annual meeting until all dividends in arrears (including the then-current
quarterly dividend payment) have been paid or declared and set apart for
payment. Upon payment or declaration and reservation of funds for payment of
all such dividends, the term of office of each director elected shall
immediately terminate and the number of directors shall be such number as may
be provided for in the Company Certificate or Bylaws.
 
  The Junior Preferred Stock is not subject to redemption. The terms of the
Junior Preferred Stock provide that the Company is subject to certain
restrictions with respect to dividends and distributions on and redemptions and
purchases of shares of stock of Host Marriott ranking junior to or on a parity
with the Junior Preferred Stock in the event that payments of dividends or
other distributions payable on the Junior Preferred Stock are in arrears.
 
                                       57

WARRANTS
 
  Host Marriott agreed to issue warrants (the "Warrants") to acquire 7,700,000
shares of the Company's Common Stock in connection with the settlement of class
action lawsuits instituted against Host Marriott and certain individual
defendants by certain holders and purchasers of senior notes and debentures of
Host Marriott. As adjusted to reflect the Special Dividend, each Warrant
entitles the holder, at any time prior to 5:00 p.m. on October 8, 1998 (the
"Expiration Time"), to purchase one share of Common Stock from the Company and
one-fifth share of HM Services common stock at a price (the "Exercise Price")
of $10.00. The portion of the Exercise Price attributable to the HM Services
common stock is payable to HM Services. Both the Exercise Price and the number
of shares subject to the Warrants are subject to certain adjustments. Warrants
that are not exercised prior to the Expiration Time expire and become void.
Host Marriott did not receive any proceeds from the issuance of the Warrants.
 
  Warrantholders will not be entitled to vote or to consent or to receive
notice as shareholders in respect of the meeting of shareholders or the
election of directors of Host Marriott or any other matter, or possess any
rights whatsoever as Host Marriott.
 
  Host Marriott has also agreed to use its reasonable best efforts to obtain
any required approvals or registration under state securities laws for the
issuance of the Common Stock upon exercise of the Warrants. Under the Warrant
Agreement, however, Warrants may not be exercised by or, shares of Common Stock
issued to, any Warrant holder in any state where such exercise or issuance
would be unlawful. The Warrants have no established trading market and no
assurance can be given that any such markets will develop.
 
  As of January 3, 1997, approximately 600,000 Warrants were outstanding or
reserved for issuance.

     PURPOSES AND ANTITAKEOVER EFFECTS OF CERTAIN PROVISIONS OF THE COMPANY
      CERTIFICATE AND BYLAWS AND THE MARRIOTT INTERNATIONAL PURCHASE RIGHT
 
COMPANY CERTIFICATE AND BYLAWS
 
  The Company Certificate contains several provisions that will make difficult
an acquisition of control of the Company by means of a tender offer, open
market purchases, a proxy fight or otherwise, that is not approved by the
Board. The Company's Bylaws (the "Bylaws") also contain provisions that could
have an antitakeover effect.
 
  The purposes of the relevant provisions of the Company Certificate and Bylaws
are to discourage certain types of transactions, described below, which may
involve an actual or threatened change of control of the Company and to
encourage persons seeking to acquire control of the Company to consult first
with the Board to negotiate the terms of any proposed business combination or
offer. The provisions are designed to reduce the vulnerability of Host Marriott
to an unsolicited proposal for a takeover that does not contemplate the
acquisition of all outstanding shares or is otherwise unfair to shareholders of
Host Marriott or an unsolicited proposal for the restructuring or sale of all
or part of Host Marriott. Host Marriott believes that, as a general rule, such
proposals would not be in the best interests of the Company and its
shareholders.
 
  There has been a history of the accumulation of substantial stock positions
in public companies by third parties as a prelude to proposing a takeover or a
restructuring or sale of all or part of the company or another similar
extraordinary corporate action. Such actions are often undertaken by the third-
party without advance notice to, or consultation with, the management or board
of directors of the target company. In many cases, the purchaser seeks
representation on the company's board of directors in order to increase the
likelihood that its proposal will be implemented by the company. If the company
resists the efforts of the purchaser to obtain representation on the company's
board, the purchaser may commence a proxy contest to have its nominees elected
to the board in place of certain directors or the entire board. In some cases,
the purchaser may not truly be interested in taking over the company, but may
use the threat of a proxy fight and/or a bid to take over the company as a
means of forcing the company to repurchase its equity position at a substantial
premium over market price.
 
  Host Marriott believes that the imminent threat of removal of Host Marriott's
management or Board in such situations would severely curtail the ability of
management or the Board to negotiate effectively with such purchasers. The
management or the Board would be deprived of the time and information necessary
to evaluate the takeover proposal, to study alternative proposals and to help
ensure that the best price is obtained in any transaction involving the Company
which may ultimately be undertaken. If the real purpose of a takeover bid were
to force the Company to repurchase an accumulated stock interest at a premium
price, management or the Board would face the risk that, if it did not
repurchase the purchaser's stock interest, Host Marriott's business and
management would be disrupted, perhaps irreparably.
 
  Certain provisions of the Company Certificate and Bylaws, Host Marriott
believes, will help ensure that the Board, if confronted by a surprise proposal
from a third party which has acquired a block of stock, will have sufficient
time to review the proposal and appropriate alternatives to the proposal and to
act in what it believes to be the best interests of the shareholders. In
addition, certain other provisions of the Company Certificate are designed to
prevent a purchaser from utilizing two-tier pricing and similar inequitable
tactics in the event of an attempt to take over Host Marriott.
 
  These provisions, individually and collectively, will make difficult and may
discourage a merger, tender offer or proxy fight, even if such transaction or
occurrence may be favorable to the interests of the shareholders, and may delay
or frustrate the assumption of control by a holder of a large block of stock of
Host Marriott and the removal of incumbent management, even if such removal
might be
 
                                       59
<PAGE>
 
beneficial to the shareholders. Furthermore, these provisions may deter or
could be utilized to frustrate a future takeover attempt which is not approved
by the incumbent Board, but which the holders of a majority of the shares may
deem to be in their best interests or in which shareholders may receive a
substantial premium for their stock over prevailing market prices of such
stock. By discouraging takeover attempts, these provisions might have the
incidental effect of inhibiting certain changes in management (some or all of
the members of which might be replaced in the course of a change of control)
and also the temporary fluctuations in the market price of the stock which
often result from actual or rumored takeover attempts. Set forth below is a
description of such provisions in the Company Certificate and Bylaws. Such
description is intended as a summary only and is qualified in its entirety by
reference to the Company Certificate and Bylaws.
 
 CLASSIFIED BOARD OF DIRECTORS
 
  The Company Certificate provides for the Board to be divided into three
classes serving staggered terms so that directors' current terms will expire at
the 1997, 1998 or 1999 annual meeting of shareholders.
 
  The classification of directors will have the effect of making it more
difficult for shareholders to change the composition of the Board in a
relatively short period of time. At least two annual meetings of shareholders,
instead of one, will generally be required to effect a change in a majority of
the Board. Such a delay may help ensure that the Board, if confronted by a
holder attempting to force a stock repurchase at a premium above market prices,
a proxy contest or an extraordinary corporate transaction, will have sufficient
time to review the proposal and appropriate alternatives to the proposal and to
act in what it believes are the best interests of the shareholders.
 
  The classified board provision could have the effect of discouraging a third
party from making a tender offer or otherwise attempting to obtain control of
Host Marriott, even though such an attempt might be beneficial to the Company
and its shareholders. The classified board provision could thus increase the
likelihood that incumbent directors will retain their positions. In addition,
since the classified board provision is designed to discourage accumulations of
large blocks of Host Marriott's stock by purchasers whose objective is to have
such stock repurchased by the Company at a premium, the classified board
provision could tend to reduce the temporary fluctuations in the market price
of Host Marriott's stock that could be caused by accumulations of large blocks
of such stock. Accordingly, shareholders could be deprived of certain
opportunities to sell their stock at a temporarily higher market price.
 
  Host Marriott believes that a classified board of directors helps to assure
the continuity and stability of the Board and business strategies and policies
as determined by the Board, because generally a majority of the directors at
any given time will have had prior experience as directors of Host Marriott.
The classified board provision also helps assure that the Board, if confronted
with an unsolicited proposal from a third party that has acquired a block of
the voting stock of Host Marriott, will have sufficient time to review the
proposal and appropriate alternatives and to seek the best available result for
all shareholders.
 
 REMOVAL; FILLING VACANCIES
 
  The Company Certificate provides that, subject to any rights of the holders
of preferred stock, only a majority of the Board then in office shall have the
authority to fill any vacancies on the Board, including vacancies created by an
increase in the number of directors. In addition, the Company Certificate
provides that a new director elected to fill a vacancy on the Board will serve
for the remainder of the full term of his or her class and that no decrease in
the number of directors shall shorten the term of an incumbent. Moreover, the
Company Certificate provides that directors may be removed with or without
cause only by the affirmative vote of holders of at least 66 2/3% of the voting
 
                                       60
<PAGE>
 
power of the shares entitled to vote at the election of directors, voting
together as a single class. These provisions relating to removal and filling of
vacancies on the Board will preclude shareholders from enlarging the Board or
removing incumbent directors and filling the vacancies with their own nominees.
 
 LIMITATIONS ON SHAREHOLDER ACTION BY WRITTEN CONSENT; SPECIAL MEETINGS
 
  The Company Certificate and Bylaws provide that shareholder action can be
taken only at an annual or special meeting of shareholders and prohibit
shareholder action by written consent in lieu of a meeting. The Company
Certificate and Bylaws provide that, subject to the rights of holders of any
series of preferred stock, special meetings of shareholders can be called only
by a majority of the entire Board. Shareholders are not permitted to call a
special meeting or to require that the Board call a special meeting of
shareholders. Moreover, the business permitted to be conducted at any special
meeting of shareholders is limited to the business brought before the meeting
by or at the direction of the Board.
 
  The provisions of the Company Certificate and Bylaws restricting shareholder
action by written consent may have the effect of delaying consideration of a
shareholder proposal until the next annual meeting unless a special meeting is
called by a majority of the entire Board. These provisions would also prevent
the holders of a majority of the voting power of the voting stock from using
the written consent procedure to take shareholder action and from taking action
by consent without giving all the shareholders entitled to vote on a proposed
action the opportunity to participate in determining such proposed action.
Moreover, a shareholder could not force shareholder consideration of a proposal
over the opposition of the Board by calling a special meeting of shareholders
prior to the time the Board believed such consideration to be appropriate.
 
  Host Marriott believes that such limitations on shareholder action will help
to assure the continuity and stability of the Board and Host Marriott's
business strategies and policies as determined by the Board, to the benefit of
all of the Company's shareholders. If confronted with an unsolicited proposal
from Company shareholders, the Board will have sufficient time to review such
proposal and to seek the best available result for all shareholders, before
such proposal is approved by such shareholders by written consent in lieu of a
meeting or through a special meeting of shareholders.
 
 NOMINATIONS OF DIRECTORS AND SHAREHOLDER PROPOSALS
 
  The Bylaws establish an advance notice procedure with regard to the
nomination, other than by or at the direction of the Board, of candidates for
election as directors (the "Nomination Procedure") and with regard to
shareholder proposals to be brought before an annual or special meeting of
shareholders (the "Business Procedure").
 
  The Nomination Procedure provides that only persons who are nominated by or
at the direction of the Board, or by a shareholder who has given timely prior
written notice to the Corporate Secretary of Host Marriott prior to the meeting
at which directors are to be elected, will be eligible for election as
directors. The Business Procedure provides that shareholder proposals must be
submitted in writing in a timely manner in order to be considered at any annual
or special meeting. To be timely, notice must be received by Host Marriott (i)
in the case of an annual meeting, not less than 90 days prior to the annual
meeting for a director nomination, and not less than 120 days prior to the
annual meeting for a shareholder proposal or (ii) in the case of a special
meeting not later than the seventh day following the day on which notice of
such meeting is first given to shareholders for both a director nomination and
a shareholder proposal.
 
  Under the Nomination Procedure, notice to Host Marriott from a shareholder
who proposes to nominate a person at a meeting for election as a director must
contain certain information about that person, including age, business and
residence addresses, principal occupation, the class and number
 
                                       61
<PAGE>
 
of shares of Common Stock beneficially owned, the consent to be nominated and
such other information as would be required to be included in a proxy statement
soliciting proxies for the election of the proposed nominee, and certain
information about the shareholder proposing to nominate that person. Under the
Business Procedure, notice relating to a shareholder proposal must contain
certain information about such proposal and about the shareholder who proposes
to bring the proposal before the meeting, including the class and number of
shares of Common Stock beneficially owned by such shareholder. If the Chairman
or other officer presiding at a meeting determines that a person was not
nominated in accordance with the Nomination Procedure, such person will not be
eligible for election as a director, or if he determines that the shareholder
proposal was not properly brought before such meeting, such proposal will not
be introduced at such meeting. Nothing in the Nomination Procedure or the
Business Procedure will preclude discussion by any shareholder of any
nomination or proposal properly made or brought before an annual or special
meeting in accordance with the above-mentioned procedures.
 
  The purpose of the Nomination Procedure is, by requiring advance notice of
nomination by shareholders, to afford the Board a meaningful opportunity to
consider the qualifications of the proposed nominees and, to the extent deemed
necessary or desirable by the Board, to inform shareholders about such
qualifications. The purpose of the Business Procedure is, by requiring advance
notice of shareholder proposals, to provide a more orderly procedure for
conducting annual meetings of shareholders and, to the extent deemed necessary
or desirable by the Board, to provide the Board with a meaningful opportunity
to inform shareholders, prior to such meetings, of any proposal to be
introduced at such meetings, together with any recommendation as to the Board's
position or belief as to action to be taken with respect to such proposal, so
as to enable shareholders better to determine whether they desire to attend
such meeting or grant a proxy to the Board as to the disposition of any such
proposal. Although the Bylaws do not give the Board any power to approve or
disapprove shareholder nominations for the election of directors or of any
other proposal submitted by shareholders, the Bylaws may have the effect of
precluding a nomination for the election of directors or precluding the
conducting of business at a particular shareholder meeting if the proper
procedures are not followed, and may discourage or deter a third-party from
conducting a solicitation of proxies to elect its own slate of directors or
otherwise attempting to obtain control of the Company, even if the conduct of
such solicitation or such attempt might be beneficial to the Company and its
shareholders.
 
 FAIR PRICE PROVISION
 
  Article Fifteen of the Company Certificate (the "Fair Price Provision")
requires approval by the holders of 66 2/3% of the voting power of the
outstanding capital stock of the Company entitled to vote generally in the
election of directors (the "Voting Stock") as a condition for mergers and
certain other business combinations ("Business Combinations") involving the
Company and any holder of more than 25% of such voting power (an "Interested
Shareholder") unless the transaction is either (i) approved by a majority of
the members of the Board who are not affiliated with the Interested Shareholder
and who were directors before the Interested Shareholder became an Interested
Shareholder (the "Disinterested Directors") or (ii) certain minimum price and
procedural requirements are met.
 
  The Fair Price Provision is designed to prevent a third party from utilizing
two-tier pricing and similar inequitable tactics in a takeover attempt. The
Fair Price Provision is not designed to prevent or discourage tender offers for
the Company. It does not impede an offer for at least 66 2/3% of the Voting
Stock in which each shareholder receives substantially the same price for his
or her shares as each other shareholder or which the Board has approved in the
manner described herein. Nor does the Fair Price Provision preclude a third
party from making a tender offer for some of the shares of Voting Stock without
proposing a Business Combination in which the remaining shares of Voting Stock
are purchased. Except for the restrictions on Business Combinations, the Fair
Price Provision will not prevent an Interested Shareholder having a controlling
interest of the Voting Stock from exercising control over Host Marriott or
increasing its interest in Host Marriott. Moreover, an Interested
 
                                       62
<PAGE>
 
Shareholder could increase its ownership to 66 2/3% and avoid application of
the Fair Price Provision. However, the separate provisions contained in the
Company Certificate and the Bylaws relating to "Classified Boards of Directors"
discussed above will, as therein indicated, curtail an Interested Shareholder's
ability to exercise control in several respects, including such shareholder's
ability to change incumbent directors who may oppose a Business Combination or
to implement a Business Combination by written consent without a shareholder
meeting. The Fair Price Provision would, however, discourage some takeover
attempts by persons intending to acquire the Company in two steps and to
eliminate remaining shareholder interests by means of a business combination
involving less consideration per share than the acquiring person would propose
to pay for its initial interest in the Company. In addition, acquisitions of
stock by persons attempting to acquire control through market purchases may
cause the market price of the stock to reach levels which are higher than would
otherwise be the case. The Fair Price Provision may thereby deprive some
holders of the Common Stock of an opportunity to sell their shares at a
temporarily higher market price.
 
  Although the Fair Price Provision is designed to help assure fair treatment
of all shareholders vis-a-vis other shareholders in the event of a takeover, it
is not the purpose of the Fair Price Provision to assure that shareholders will
receive a premium price for their shares in a takeover. Accordingly, the Board
is of the view that the adoption of the Fair Price Provision does not preclude
the Board's opposition to any future takeover proposal which it believes would
not be in the best interests of the Company and its shareholders, whether or
not such a proposal satisfies the minimum price criteria and procedural
requirements of the Fair Price Provision.
 
  In addition, under Section 203 of the Delaware General Corporation Law as
applicable to Host Marriott, certain "business combinations" (defined generally
to include (i) mergers or consolidations between a Delaware corporation and an
interested shareholder (as defined below) and (ii) transactions between a
Delaware corporation and an interested shareholder involving the assets or
stock of such corporation or its majority-owned subsidiaries, including
transactions which increase the interested shareholder's percentage ownership
of stock) between a Delaware corporation, whose stock generally is publicly
traded or held of record by more than 2,000 shareholders, and an interested
shareholder (defined generally as those shareholders, who, on or after December
23, 1987, become beneficial owners of 15% or more of a Delaware corporation's
voting stock) are prohibited for a three-year period following the date that
such shareholder became an interested shareholder, unless (i) prior to the date
such shareholder became an interested shareholder, the board of directors of
the corporation approved either the business combination or the transaction
which resulted in the shareholder becoming an interested shareholder, (ii) upon
consummation of the transaction that made such shareholder an interested
shareholder, the interested shareholder owned at least 85% of the voting stock
of the corporation outstanding at the time the transaction commenced (excluding
voting stock owned by officers who also are directors and voting stock held in
employee benefit plans in which the employees do not have a confidential right
to tender or vote stock held by the plan), or (iii) the business combination
was approved by the board of directors of the corporation and ratified by two-
thirds of the voting stock which the interested shareholder did not own. The
three-year prohibition also does not apply to certain business combinations
proposed by an interested shareholder following the announcement or
notification of certain extraordinary transactions involving the corporation
and a person who had been an interested shareholder during the previous three
years or who became an interested shareholder with the approval of a majority
of the corporation's directors.
 
  SHAREHOLDER RIGHTS PLAN
 
  Host Marriott has adopted a shareholder rights plan which may have anti-
takeover effects. See "Description of Host Marriott Capital Stock--Rights and
Junior Preferred Stock."
 
  AMENDMENT OF THE COMPANY CERTIFICATE AND BYLAWS
 
  The Company Certificate contains provisions requiring the affirmative vote of
the holders of at least 66 2/3% the voting power of the stock entitled to vote
generally in the election of directors to
 
                                       63
<PAGE>
 
amend certain provisions of the Company Certificate and Bylaws (including the
provisions discussed above). These provisions make it more difficult for
shareholders to make changes in the Company Certificate or Bylaws, including
changes designed to facilitate the exercise of control over the Company. In
addition, the requirement for approval by at least a 66 2/3% shareholder vote
will enable the holders of a minority of the Company's capital stock to prevent
holders of a less-than-66 2/3% majority from amending such provisions of the
Company's Certificate or Bylaws.
 
MARRIOTT INTERNATIONAL PURCHASE RIGHT
 
  Host Marriott granted to Marriott International, for a period of ten years
following the Marriott International Distribution (i.e., until October 2003),
the right to purchase a number of shares equal in amount of up to 20% of each
class of Host Marriott's outstanding voting stock at the then fair market value
upon the occurrence of certain change of control events involving the Company.
The Marriott International Purchase Right may be exercised for a 30-day period
following the date a person or group of affiliated persons has (i) become the
beneficial owner of 20% or more of the total voting power of the then
outstanding shares of the Company's voting stock or (ii) announced a tender
offer for 30% or more of the total voting power of the then outstanding shares
of the Company's voting stock. These change of control events upon which the
Marriott International Purchase Right becomes exercisable are substantially
identical to those events that cause a distribution of the Rights under the
Rights Agreement (see "Description of Host Marriott Capital Stock--Rights and
Junior Preferred Stock"). Accordingly, certain share ownership of the Company's
voting stock by specified persons is exempt under the Rights Agreement, and
consequently will not result in a distribution of Rights, and will not cause
the Marriott International Purchase Right to become exercisable.
 
  In connection with the Marriott International Distribution, the Board amended
the terms of the Rights Agreement to provide that the exercise of the Marriott
International Purchase Right will not result in a distribution of the Rights.
Accordingly, upon exercise of the Marriott International Purchase Right,
Marriott International will be entitled to receive the Rights associated with
the Common Stock and will not be deemed an "Acquiring Person" under the Rights
Agreement.
 
  The purchase price for the Common Stock to be purchased upon the exercise of
the Marriott International Purchase Right is determined by taking the average
of the closing sale price of the Common Stock during the 30 consecutive trading
days preceding the date the Marriott International Purchase Right becomes
exercisable. The specific terms of the Marriott International Purchase Right
are set forth in the Marriott International Distribution Agreement.
 
  The Marriott International Purchase Right will have an antitakeover effect.
Any person considering acquiring a substantial or controlling block of Common
Stock would face the possibility that its ability to exercise control would be
impaired by Marriott International's 20% ownership resulting from exercise of
the Marriott International Purchase Right. Moreover, so long as the Marriott
family's current percentage of ownership of Common Stock continues, the
combined Marriott family (including various trusts established by members of
the Marriott family) and Marriott International ownership following exercise of
the Marriott International Purchase Right may effectively block control by
others (see "Description of Host Marriott Capital Stock"). It is also possible
that the exercise price of the Marriott International Purchase Right would be
lower than the price at which a potential acquiror might be willing to purchase
a 20% block of shares of Common Stock because the purchase price for the
Marriott International Purchase Right is based on the average trading price
during a 30-day period which may be prior to the announcement of the takeover
event. This potential price differential may have a further antitakeover effect
by discouraging potential acquirers of Host Marriott. The antitakeover effect
of the Marriott International Purchase Right will be in addition to the
antitakeover effects of the provisions contained in the Company Certificate and
Bylaws.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
  The following is a summary of certain of the material United States Federal
income tax consequences of the purchase, ownership and disposition of the
Preferred Securities. Unless otherwise stated, this summary deals only with
Preferred Securities held as capital assets. It does not deal with special
classes of holders such as banks, thrifts, real estate investment trusts,
regulated investment companies, insurance companies, dealers in securities or
currencies, tax-exempt investors, foreign corporations and persons who are not
citizens or residents of the United States (except to the extent discussed
under the heading "Certain United States Tax Consequences to Non-United States
Holders") or persons that will hold the Preferred Securities as a position in a
"straddle," as part of a "synthetic security" or "hedge," as part of a
"conversion transaction" or other integrated investment, or as other than a
capital asset. This summary also does not address the tax consequences to
persons that have a functional currency other than the U.S. Dollar. Further, it
does not include any description of any alternative minimum tax consequences or
the tax laws of any state or local government or of any foreign government that
may be applicable to the Preferred Securities. This summary is based on the
Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations
thereunder and administrative and judicial interpretations thereof, as of the
date hereof, all of which are subject to change, possibly on a retroactive
basis.
 
  INVESTORS ARE ADVISED TO CONSULT THEIR TAX ADVISORS AS TO THE UNITED STATES
FEDERAL INCOME TAX CONSEQUENCES OF THE OWNERSHIP AND DISPOSITION OF PREFERRED
SECURITIES IN LIGHT OF THEIR PARTICULAR CIRCUMSTANCES, AS WELL AS THE EFFECT OF
ANY STATE, LOCAL, FOREIGN OR OTHER TAX LAWS AND OF POTENTIAL CHANGES IN
APPLICABLE TAX LAWS.
 
CLASSIFICATION OF THE DEBENTURES
 
  Host Marriott has taken the position that the Debentures will be classified
for United States Federal income tax purposes as indebtedness of Host Marriott
under current law and, by acceptance of Preferred Securities, each holder
covenants to treat the Debentures as indebtedness and the Preferred Securities
as evidence of an indirect beneficial ownership interest in the Debentures. No
assurance can be given, however, that such position of Host Marriott will not
be challenged by the Internal Revenue Service or, if challenged, that such a
challenge will not be successful. The remainder of this discussion assumes that
the Debentures will be classified as indebtedness of Host Marriott for United
States Federal income tax purposes.
 
CLASSIFICATION OF THE ISSUER
 
  In connection with the issuance of the Preferred Securities, Latham &
Watkins, special United States tax counsel to the Issuer and Host Marriott,
rendered its opinion generally to the effect that, under then current law and
assuming full compliance with the terms of the Trust Agreement and the
Indenture (and certain other documents), based on certain facts and assumptions
contained in such opinion, the Trust will be classified for United States
Federal income tax purposes as a grantor trust and not as an association
taxable as a corporation. Accordingly, for United States Federal income tax
purposes, each holder of Preferred Securities generally will be considered the
owner of an undivided interest in the Debentures, and each holder will be
required to include in its gross income any original issue discount accrued
with respect to its allocable share of those Debentures.
 
ORIGINAL ISSUE DISCOUNT
 
  Because Host Marriott has the option, under the terms of the Debentures, to
defer payments of interest by extending interest payment periods for up to 60
months, all of the stated interest payments
 
                                       65
<PAGE>
 
on the Debentures will be treated as "original issue discount." Under the Code,
holders of debt instruments (such as the Debentures) issued with original issue
discount must include that discount in income on an economic accrual basis
before the receipt of cash attributable to the interest, regardless of their
method of tax accounting. Generally, all of a holder's taxable interest income
with respect to the Debentures will be accounted for as original issue
discount. Actual payments and distributions of stated interest will not,
however, be separately reported as taxable income. The amount of original issue
discount that accrues in any quarter will approximately equal the amount of the
interest that accrues on the Debentures in that quarter at the stated interest
rate. In the event that the interest payment period is extended, holders will
continue to accrue original issue discount in an amount approximately equal to
the amount of the interest payment due at the end of the extended interest
payment period on an economic accrual basis over the length of the extended
interest payment period.
 
  Because income on the Debentures will constitute original issue discount,
corporate holders will not be entitled to a dividends-received deduction with
respect to any income recognized with respect to the Debentures.
 
LIQUIDATED DAMAGES
 
  Host Marriott intends to take the position that the Liquidated Damages
described above under "Description of the Preferred Securities--Registration
Rights" will be taxable to a holder as ordinary income in accordance with the
holder's usual method of income tax accounting. The IRS may take a different
position, however, which could affect both the timing of the holder's income
and the timing and amount of Host Marriott's deduction with respect to the
Liquidated Damages.
 
REDEMPTION OF PREFERRED SECURITIES FOR DEBENTURES OR CASH UPON LIQUIDATION OF
THE ISSUER
 
  Under certain circumstances, the Debentures may be distributed to holders in
exchange for the Preferred Securities. Under current law, such a distribution
to holders, for United States Federal income tax purposes, would be treated as
a nontaxable event to each holder, and each holder would receive an aggregate
tax basis in the Debentures distributed equal to such holder's aggregate tax
basis in its Preferred Securities exchanged therefor. A holder's holding period
in the Debentures so received would include the period during which the
Preferred Securities were held by such holder. If, however, the exchange is
caused by a Tax Event which results in the Issuer being treated as an
association taxable as a corporation the distribution would likely constitute a
taxable event to the Issuer and holders of the Preferred Securities.
 
  Under certain circumstances described herein (see "Special Event Exchange or
Redemption"), the Debentures may be redeemed for cash and the proceeds of such
redemption distributed to holders in redemption of their Preferred Securities.
Under current law, such a redemption would, for United States Federal income
tax purposes, constitute a taxable disposition of the redeemed Preferred
Securities, and a holder would recognize gain or loss in the same manner as if
it sold such redeemed Preferred Securities for cash. See "--Sales of Preferred
Securities".
 
SALES OF PREFERRED SECURITIES
 
  A holder that sells Preferred Securities will recognize gain or loss equal to
the difference between the amount realized on the sale of the Preferred
Securities and the holder's adjusted tax basis in such Preferred Securities. A
holder's adjusted tax basis in the Preferred Securities generally will be its
initial purchase price increased by original issue discount previously
includible in such holder's gross income to the date of disposition and
decreased by payments received on the Preferred Securities to the date of
disposition. In general, such gain or loss will be a capital gain or loss and
will be a long-term capital gain or loss if the Preferred Securities have been
held for more than one year at the time of sale.
 
 
                                       66
<PAGE>
 
  The Preferred Securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
Debentures. A holder who disposes of or converts his Preferred Securities
between record dates for payments of distributions thereon will be required to
include accrued but unpaid interest on the Debentures through the date of
disposition or conversion in income as ordinary income, and to add such amount
to his adjusted tax basis in his pro rata share of the underlying Debentures
deemed disposed of or converted. To the extent the selling price is less than
the holder's adjusted tax basis (which basis will include, in the form of
original issue discount, all accrued but unpaid interest), a holder will
recognize a capital loss. Subject to certain limited exceptions, capital losses
cannot be applied to offset ordinary income for United States Federal income
tax purposes.
 
MARKET DISCOUNT AND BOND PREMIUM
 
  To the extent a holder acquires its Preferred Securities at a price that is
greater or less than the adjusted issue price of such holder's proportionate
share of the Debentures (which generally should approximate the face amount
plus accrued but unpaid interest on the Debentures), the holder may be deemed
to have acquired its undivided interest in the Debentures with acquisition
premium or market discount. A holder who purchases Preferred Securities at a
premium will be permitted to reduce the amount of original issue discount
required to be included in income to reflect the acquisition premium. A holder
who purchases Preferred Securities at a market discount will include the amount
of such discount in income in accordance with the market discount rules
described below.
 
  A holder that acquires its undivided beneficial interest in the Debentures at
a market discount generally will be required to recognize ordinary income to
the extent of accrued market discount on the Debentures upon their retirement
or, to the extent of any gain, upon the disposition of the Preferred
Securities. Such market discount will accrue ratably or, at the election of the
holder, under a constant yield method over the remaining term of the
Debentures. A holder will also be required to defer the deduction of a portion
of the interest paid or accrued on indebtedness incurred to purchase or carry
Preferred Securities that represent an undivided interest in Debentures
acquired with market discount. In lieu of the foregoing, a holder may elect to
include market discount in income currently as it accrues on all market
discount instruments acquired by such holder in the taxable year of the
election or thereafter, in which case the interest deferral rules will not
apply.
 
  A holder may elect, in lieu of applying the market discount or acquisition
premium rules described above, to account for all income under the Debentures
as if it were original issue discount. A holder that makes this election and
that is considered to have acquired its beneficial interest in the Debentures
with market discount will be considered to have made the election described in
the immediately preceding paragraph.
 
CONVERSION OF PREFERRED SECURITIES INTO HOST MARRIOTT COMMON STOCK
 
  Except possibly to the extent attributable to accrued and unpaid interest on
the Debentures, a holder of Preferred Securities will not recognize income,
gain or loss upon the conversion of the Preferred Securities into Host Marriott
Common Stock through the Conversion Agent. A holder of Preferred Securities
will, however, recognize gain upon the receipt of cash in lieu of a fractional
share of Host Marriott Common Stock equal to the amount of cash received less
such holder's tax basis in such fractional share. Such a holder's tax basis in
the Host Marriott Common Stock received upon conversion should generally be
equal to such holder's tax basis in the Preferred Securities delivered to the
Conversion Agent for exchange less the basis allocated to any fractional share
for which cash is received and such holder's holding period in the Host
Marriott Common Stock received upon conversion should generally begin on the
date such holder acquired the Preferred Securities delivered to the Conversion
Agent for exchange.
 
  Holders of Preferred Securities should not recognize gain or loss upon
expiration of the conversion rights. Such expiration should not effect a
significant modification of the underlying Debentures within
 
                                       67
<PAGE>
 
the meaning of applicable Treasury Regulations, and thus will not be considered
a sale or exchange for purposes of federal income taxation.
 
ADJUSTMENT OF CONVERSION PRICE
 
  Treasury Regulations promulgated under Section 305 of the Code would treat
holders of Preferred Securities as having received a constructive distribution
from Host Marriott in the event the conversion ratio of the Debentures were
adjusted if (i) as a result of such adjustment, the proportionate interest
(measured by the quantum of Host Marriott Common Stock into or for which the
Debentures are convertible or exchangeable) of the holders of the Preferred
Securities in the assets or earnings and profits of Host Marriott were
increased, and (ii) the adjustment was not made pursuant to a bona fide,
reasonable antidilution formula. An adjustment in the conversion ratio would
not be considered made pursuant to such a formula if the adjustment was made to
compensate for certain taxable distributions with respect to the Host Marriott
Common Stock. Thus, under certain circumstances, a reduction in the conversion
price for the holders may result in deemed dividend income to holders to the
extent of the current or accumulated earnings and profits of Host Marriott.
Holders of the Preferred Securities would be required to include their
allocable share of such deemed dividend income in gross income but would not
receive any cash related thereto.
 
INFORMATION REPORTING TO HOLDERS
 
  The Issuer will report the original issue discount, if any, that accrued
during the year with respect to the Debentures, and any gross proceeds received
by the Issuer from the retirement or redemption of the Debentures, annually to
the holders of record of the Preferred Securities and the Internal Revenue
Service. The Issuer currently intends to deliver such reports to holders of
record prior to January 31 following each calendar year. It is anticipated that
persons who hold Preferred Securities as nominees for beneficial holders will
report the required tax information to beneficial holders on Form 1099.
 
BACKUP WITHHOLDING
 
  Payments made on, and proceeds from the sale of, Preferred Securities may be
subject to a "backup" withholding tax of 31% unless the holder complies with
certain identification requirements. Any withheld amounts will generally be
allowed as a credit against the holder's Federal income tax, provided the
required information is timely filed with the Internal Revenue Service.
 
POSSIBLE TAX LEGISLATION
 
  As part of President Clinton's Fiscal 1997 Budget Proposal, the Treasury
Department proposed legislation that, among other things, would have treated as
equity for United States Federal income tax purposes instruments with a maximum
term of more than 20 years that are not shown as indebtedness on the
consolidated balance sheet of the issuer. The legislation was to be effective
for debt instruments issued on or after December 7, 1995. Although this
legislation was not enacted as part of the Fiscal 1997 Budget, there can be no
assurance that a similar proposal would not be enacted in the future, that such
future legislation would not have a retroactive effective date and that such
future legislation would not prevent Host Marriott from deducting interest on
the Debentures. This would constitute a Tax Event and would permit the Issuer
to exchange the Preferred Securities, in whole or in part, for the Debentures.
See "Description of the Preferred Securities--Special Event Exchange or
Redemption."
 
CERTAIN UNITED STATES TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS
 
  GENERAL. The following is a general discussion of certain United States
Federal income and estate tax consequences of the acquisition, ownership and
disposition of Preferred Securities by a "Non-United States Holder" and does
not deal with tax consequences arising under the laws of any
 
                                       68
<PAGE>
 
foreign, state, or local jurisdiction. As used herein, a "Non-United States
Holder" is a person or entity that, for United States Federal income tax
purposes, is not a citizen or resident of the United States, a corporation,
partnership, or other entity created or organized under the laws of the United
States or a political subdivision thereof, or an estate or trust, the income of
which is subject to United States Federal income taxation regardless of its
source, or that otherwise is subject to United States federal income taxation
on a net basis in respect of the Preferred Securities. The tax treatment of the
holders of the Preferred Securities may vary depending upon their particular
situations. Certain holders (including insurance companies, tax exempt
organizations, financial institutions and broker-dealers) may be subject to
special rules not discussed below. Prospective investors who are Non-United
States Holders are urged to consult their tax advisors regarding the United
States Federal tax consequences of acquiring, holding and disposing of
Preferred Securities and Host Marriott Common Stock, as well as any tax
consequences that may arise under the laws of any foreign, state, local or
other taxing jurisdiction.
 
  INTEREST. Interest (including original issue discount) received or accrued by
a Non-United States Holder of Preferred Securities will not be subject to
United States Federal income or withholding tax if such interest is not
effectively connected with the conduct of a trade or business within the United
States by such Non-United States Holder and (i) the Non-United States Holder
does not actually or constructively own 10% or more of the total voting power
of all voting stock of Host Marriott and is not a controlled foreign
corporation with respect to which Host Marriott is a "related person" within
the meaning of the Code and (ii) the beneficial owner of the Preferred
Securities certifies, under penalties
of perjury, that the beneficial owner is not a United States person and provide
the beneficial owner's name and address.
 
  GAIN ON DISPOSITION OF PREFERRED SECURITIES. A Non-United States Holder will
generally not be subject to United States federal income tax on gain recognized
on a sale, redemption or other disposition of a Preferred Security unless (i)
the gain is effectively connected with the conduct of a trade or business
within the United States by the Non-United States Holder, (ii) in the case of a
Non-United States Holder who is a nonresident alien individual and holds the
Preferred Security as a capital asset, such holder is present in the United
States for 183 or more days in the taxable year and certain other requirements
are met.
 
  DIVIDENDS ON HOST MARRIOTT COMMON STOCK. In the event that dividends are paid
on Host Marriott Common Stock, except as described below, such dividends paid
to a Non-United States Holder of Host Marriott Common Stock will be subject to
withholding of United States Federal income tax at a 30% rate or such lower
rate as may be specified by an applicable income tax treaty, unless the
dividends are effectively connected with the conduct of a trade or business of
the Non-United States Holder within the United States. If the dividend is
effectively connected with the conduct of a trade or business of the Non-United
States Holder within the United States, the dividend would be subject to United
States Federal income tax on a net income basis at applicable graduated
individual or corporate rates and would be exempt from the 30% withholding tax
described above. Any such effectively connected dividends received by a foreign
corporation may, under certain circumstances, be subject to an additional
"branch profits tax" at a 30% rate or such lower rate as may be specified by an
applicable income tax treaty.
 
  Under current United States Treasury regulations, dividends paid to an
address outside the United States are presumed to be paid to a resident of such
country for purposes of the withholding discussed above, and, under the current
interpretation of United States Treasury regulations, for purposes of
determining the applicability of a tax treaty rate. Under proposed United
States Treasury regulations, not currently in effect, however, a Non-United
States Holder of Host Marriott Common Stock who wishes to claim the benefit of
an applicable treaty rate would be required to satisfy applicable certification
and other requirements. Certain certification and disclosure requirements must
be complied with in order to be exempt from withholding under the effectively
connected income exemption discussed above.
 
                                       69
<PAGE>
 
  A Non-United States Holder of Host Marriott Common Stock that is eligible for
a reduced rate of United States withholding tax pursuant to a tax treaty may
obtain a refund of any excess amounts currently withheld by filing an
appropriate claim for refund with the United States Internal Revenue Service.
 
  GAIN ON DISPOSITION OF HOST MARRIOTT COMMON STOCK. A Non-United States Holder
generally will not be subject to United States Federal income tax on any gain
recognized on a disposition of the Host Marriott Common Stock (i) subject to
the exception discussed below, Host Marriott is or has been a "United States
real property holding corporation" (a "USRPHC") within the meaning of Section
897 (c) (2) of the Code at any time within the shorter of the five-year period
preceding such disposition or such Non-United States Holder's holding period
(the "Required Holding Period"), (ii) the gain is effectively connected with
the conduct of a trade or business within the United States of the Non-United
States Holder and, if a tax treaty applies, attributable to a permanent
establishment maintained by the Non-United States Holder, (iii) the Non-United
States Holder is an individual who holds the Host Marriott Common Stock as a
capital asset and is present in the United States for 183 days or more in the
taxable year of the disposition and either (a) such individual has a "tax home"
(as defined for United States Federal income tax purposes) in the United States
or (b) the gain is attributable to an office or other fixed place of business
maintained in the United States by such individual, or (iv) the Non-United
States Holder is subject to tax pursuant to the Code provisions applicable to
certain United States expatriates. If an individual Non-United States Holder
falls under clauses (ii) or (iv) above, he or she will be taxed on his or her
net gain derived from the sale under regular United States Federal income tax
rates. If the individual Non-United States Holder falls under clauses (iii)
above, he or she will be subject to a flat 30% tax on the gain derived from the
sale which may be offset by United States capital losses (notwithstanding the
fact that he or she is not considered a resident of the United States). If a
Non-United States Holder that is a foreign corporation falls under clause (ii)
above, it will be taxed on its gain under regular graduated United States
Federal income tax rates and, in addition, will under certain circumstances be
subject to the branch profits tax equal to 30% of its "effectively connected
earnings and profits" within the meaning of the Code for the taxable year, as
adjusted for certain items, unless it qualifies for a lower rate under an
applicable income tax treaty.
 
  A corporation is generally a USRPHC if the fair amount value of its United
States real property interests equals or exceeds 50% of the sum of the fair
market value of its worldwide real property interests plus its other assets
used or held for use in a trade or business. While not free from doubt, Host
Marriott believes that it currently is a USRPHC; however, a Non-United States
Holder would generally not be subject to tax or withholding in respect of such
tax on gain from a sale or other disposition of Host Marriott Common Stock by
reason of Host Marriott's USRPHC status if the Host Marriott Common Stock is
regularly traded on an established securities market ("regularly traded")
during the calendar year in which such sale or disposition occurs provided that
such holder does not own, actually or constructively, Host Marriott Common
Stock with a fair market value in excess of 5% of the fair market value of all
the Host Marriott Common Stock outstanding at any time during the Required
Holding Period. The Company believes that the Host Marriott Common Stock will
be treated as regularly traded.
 
  If Host Marriott is or has been a USRPHC within the Required Holding Period,
and if a Non-United States Holder owns in excess of 5% of the fair market value
of the outstanding Host Marriott Common Stock (as described in the preceding
paragraph), such Non-United States Holder will be subject to United States
Federal income tax at regular graduated rates under certain rules ("FIRPTA
tax") on gain recognized on a sale or other disposition of such stock. In
addition, if Host Marriott is or has been a USRPHC within the Required Holding
Period and if the Host Marriott Common Stock was not treated as regularly
traded, a Non-United States Holder (without regard to its ownership percentage)
is subject to withholding in respect of FIRPTA tax at a rate of 10% of the
amount realized on a sale or other disposition of Host Marriott Common Stock in
USRPHCs and will be further subject to FIRPTA tax in excess of the amounts
withheld. Any amount withheld pursuant to such withholding tax will be
 
                                       70
<PAGE>
 
creditable against such Non-United States Holder's United States Federal income
tax liability. Non-United States Holders are urged to consult their tax
advisors concerning the potential applicability of these provisions.
 
  FEDERAL ESTATE TAXES. A Preferred Security beneficially owned by an
individual who is a Non-United States Holder at the time of his or her death
generally will not be subject to United States Federal estate tax as a result
of such individual's death, provided that (i) such individual does not actually
or constructively own 10% or more of the total combined voting power of all
classes of stock of Host Marriott entitled to vote within the meaning of
section 871(h)(3) of the Code, and (ii) interest payments (including payments
of original issue discount) with respect to the Debentures would not have been,
if received at the time of such individual's death, effectively connected with
the conduct of a U.S. trade or business by such individual. Common stock of
Host Marriott owned, or treated as owned, by an individual Non-United States
Holder at the time of his or her death will be included in such holder's gross
estate for United States federal estate tax purposes, unless an applicable
estate tax treaty provides otherwise.
 
  INFORMATION REPORTING AND BACKUP WITHHOLDING. Host Marriott must report
annually to the Internal Revenue Service and to each Non-United States Holder
the amount of interest and dividends paid to such holder and the amount of any
tax withheld. These information reporting requirements apply regardless of
whether withholding is required. Copies of the Information returns reporting
such interest and dividends and withholding may also be made available to the
tax authorities in the country in which the Non-United States Holder resides
under the provisions of an applicable income tax treaty.
 
  In the case of payments of interest to Non-United States Holders, temporary
Treasury regulations provide that the 31% backup withholding tax and certain
information reporting will not apply to such payments with respect to which
either the requisite certification, as described above, has been received or an
exemption has otherwise been established; provided that neither Host Marriott
nor its payment agent has actual knowledge that the holder is a United States
person or that the conditions of any other exemption are not in fact satisfied.
Under temporary Treasury regulations, these information reporting and backup
withholding requirements will apply, however, to the gross proceeds paid to a
Non-United States Holder on the disposition of the Preferred Securities by or
through a United States office of a United States or foreign broker, unless the
holder certifies to the broker under penalties of perjury as to its name,
address and status as a foreign person or the holder otherwise establishes an
exemption. Information reporting requirements, but not backup withholding, will
also apply to a payment of the proceeds of a disposition of the Preferred
Securities by or through a foreign office of a United States broker or foreign
brokers with certain types of relationships to the United States. Neither
information reporting nor backup withholding generally will apply to a payment
of the proceeds of a disposition of the Preferred Securities by or through a
foreign office of a foreign broker not subject to the preceding sentence.
 
  United States backup withholding tax generally will not apply to (a) the
payment of dividends paid on Host Marriott Common Stock to a Non-United States
Holder at an address outside the United States or (b) the payment of the
proceeds of the sale of Host Marriott Common Stock to or through the foreign
office of a broker. In the case of the payment of proceeds from such a sale of
Host Marriott Common Stock through a foreign office of a broker that is a
United States person or a "U.S. related person," however, information reporting
(but not backup withholding) is required with respect to the payment unless the
broker has documentary evidence in its files that the owner is a Non-United
States Holder and certain other requirements are met or the holder otherwise
establishes an exemption. For this purpose, a "U.S. related person" is (i) a
controlled foreign corporation for United States Federal income tax purposes,
or (ii) a foreign person 50% or more of whose gross income from all sources for
the three-year period ending with the close of its taxable year preceding the
payment (or for such part of the period that the broker has been in existence)
is derived from activities that are effectively connected with the conduct of a
United States trade or business. The payment of the proceeds of a
 
                                       71
<PAGE>
 
sale of Host Marriott Common Stock to or through a United States office of a
broker is subject to information reporting and possible backup withholding
unless the owner certifies its non-United States status under penalties of
perjury or otherwise establishes an exemption.
 
  Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules may be refunded or credited against the Non-United
States Holder's United States Federal income tax liability, provided that the
required information is furnished to the Internal Revenue Service.
 
  These information and backup withholding rules are under review by the United
States Treasury and their application to the Preferred Securities and the Host
Marriott Common Stock could be changed by future regulations. On April 15,
1996, the Internal Revenue Service issued proposed Treasury Regulations
concerning the withholding of tax and reporting for certain amounts paid to
non-resident individuals and foreign corporations. The proposed regulations
would, among other changes, eliminate the presumption under current regulations
with respect to dividends paid to addresses outside the United States. The
proposed Treasury Regulations, if adopted in their present form, would be
effective for payments made after December 15, 1997. Prospective purchasers of
the Preferred Securities should consult their tax advisors concerning the
potential adoption of such Treasury Regulations.
 
                                SELLING HOLDERS
 
  The Preferred Securities were originally issued by the Issuer and sold by
Goldman, Sachs & Co., Donaldson, Lufkin & Jenrette Securities Corporation, BT
Securities Corporation and Montgomery Securities (the "Purchasers"), in a
transaction exempt from the registration requirements of the Securities Act, to
persons reasonably believed by such Purchasers to be "qualified institutional
buyers" (as defined in Rule 144A under the Securities Act). The Selling Holders
may from time to time offer and sell pursuant to this Prospectus any or all of
the Offered Securities. The term Selling Holder includes the holders listed
below and the beneficial owners of the Preferred Securities and their
transferees, pledgees, donees or other successors.
 
  The following table sets forth information with respect to the Selling
Holders of the Preferred Securities and the respective number of Preferred
Securities beneficially owned by each Selling Holder that may be offered
pursuant to this Prospectus.

  None of the Selling Holders has, or within the past three years has had, any
position, office or other material relationship with the Issuer or the Company
or any of their predecessors or affiliates. Because the Selling Holders may,
pursuant to this Prospectus, offer all or some portion of the Preferred
Securities, the Convertible Debentures or the Common Stock issuable upon
conversion of the Preferred Securities, no estimate can be given as to the
amount of the Preferred Securities, the Convertible Debentures or the Common
Stock issuable upon conversion of the Preferred Securities that will be held by
the Selling Holders upon termination of any such sales. In addition, the
Selling Holders identified above may have sold, transferred or otherwise
disposed of all or a portion of their Preferred Securities since the date on
which they provided the information regarding their Preferred Securities
included herein in transactions exempt from the registration requirements of
the Securities Act.

                              PLAN OF DISTRIBUTION
 
  The Offered Securities may be sold from time to time to purchasers directly
by the Selling Holders. Alternatively, the Selling Holders may from time to
time offer the Offered Securities to or through underwriters, broker/dealers or
agents, who may receive compensation in the form of underwriting discounts,
concessions or commissions from the Selling Holders or the purchasers of such
securities for whom they may act as agents. The Selling Holders and any
underwriters, broker/dealers or agents that participate in the distribution of
Offered Securities may be deemed to be "underwriters" within the meaning of the
Securities Act and any profit on the sale of such securities and any discounts,
commissions, concessions or other compensation received by any such
underwriter, broker/dealer or agent may be deemed to be underwriting discounts
and commissions under the Securities Act. The Offered Securities may be sold
from time to time in one or more transactions at fixed prices, at prevailing
market prices at the time of sale, at varying prices determined at the time of
sale or at negotiated prices. The sale of the Offered Securities may be
effected in transactions (which may involve crosses or block transactions) (i)
on any national securities exchange or quotation service on which the Offered
Securities may be listed or quoted at the time of sale, (ii) in the over-the-
counter market, (iii) in transactions otherwise than on such exchanges or in
the over-the-counter market or (iv) through the writing of options. At the time
a particular offering of the Offered Securities is made, a Prospectus
Supplement, if required, will be distributed which will set forth the aggregate
amount and type of Offered Securities being offered and the terms of the
offering, including the name or names of any underwriters, broker/dealers or
agents, any discounts, commissions and other terms constituting compensation
from the Selling Holders and any discounts, commissions or concessions allowed
or reallowed or paid to broker/dealers.
 
  To comply with the securities laws of certain jurisdictions, if applicable,
the Offered Securities will be offered or sold in such jurisdictions only
through registered or licensed brokers or dealers. In addition, in certain
jurisdictions the Offered Securities may not be offered or sold unless they
have been registered or qualified for sale in such jurisdictions or any
exemption from registration or qualification is available and is complied with.
 
  The Selling Holders will be subject to applicable provisions of the Exchange
Act and the rules and regulations thereunder, which provisions may limit the
timing of purchases and sales of any of the Offered Securities by the Selling
Holders. The foregoing may affect the marketability of such securities.
 
  Pursuant to the Registration Rights Agreement, the Company and the Trust
shall each bear all reasonable fees and expenses customarily borne by issuers
in a non-underwritten secondary offering by selling security holders or in an
underwritten offering, as the case may be, incurred in connection with the
performance of its obligations under the Registration Rights Agreement;
provided, however, that the Selling Holders will pay all underwriting discounts
and selling commissions, if any. The Selling Holders will be indemnified by the
Company and the Trust, jointly and severally against certain civil liabilities,
including certain liabilities under the Securities Act, or will be entitled to
contribution in connection therewith. The Company and the Trust will be
indemnified by the Selling Holders severally against certain civil liabilities,
including certain liabilities under the Securities Act, or will be entitled to
contribution in connection therewith.

activity other than holding as trust assets the Debentures of Host Marriott
and issuing the Preferred Securities and Common Securities and Host Marriott
has fully and unconditionally guaranteed all of the Issuer's obligations under
the Preferred Securities. See "Host Marriott Financial Trust," "Description of
the Preferred Securities," "Description of the Guarantee" and "Description of
the Debentures."

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  Article Eleven and Article Sixteen of the Company's Certificate and Section
7.7 of the Bylaws limit the personal liability of directors to the Company or
its shareholders for monetary damages for breach of fiduciary duty. The
provisions of the Company Certificate and Bylaws are collectively referred to
herein as the "Director Liability and Indemnification Provisions."
 
  Set forth below is a description of the Director Liability and
Indemnification Provisions. Such description is intended as a summary only and
is qualified in its entirety by reference to the Company Certificate and the
Bylaws.
 
  Elimination of Liability in Certain Circumstances. Article Sixteen of the
Company Certificate protects directors against monetary damages for breaches
of their fiduciary duty of care, except as set forth below. Under the Delaware
General Corporation Law, absent such limitation of liability provisions as are
provided in Article Sixteen, directors could generally be held liable for
gross negligence for decisions made in the performance of their duty of care
but not for simple negligence. Article Sixteen eliminates liability of
directors for negligence in the performance of their duties, including gross
negligence. In a context not involving a decision by the directors (i.e., a
suit alleging loss to the Company due to the directors' inattention to a
particular matter) a simple negligence standard might apply. Directors remain
liable for breaches of their duty of loyalty to the Company and its
shareholders, as well as acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law and transactions from
which a director derives improper personal benefit. Article Sixteen does not
eliminate director liability under Section 174 of the Delaware General
Corporation Law, which makes directors personally liable for unlawful
dividends or unlawful stock repurchases or redemptions and expressly sets
forth a negligence standard with respect to such liability.
 
  While the Director Liability and Indemnification Provisions provide
directors with protection from awards of monetary damages for breaches of the
duty of care, they do not eliminate the directors' duty of care. Accordingly,
these provisions will have no effect on the availability of equitable remedies
such as an injunction or rescission based upon a director's breach of the duty
of care. The provisions of Article Sixteen, which eliminates liability as
described above, will apply to officers of the Company only if they are
directors of the Company and are acting in their capacity as directors, and
will not apply to officers of the Company who are not directors. The
elimination of liability of directors for monetary damages in the
circumstances described above may deter persons from bringing third-party or
derivative actions against directors to the extent such actions seek monetary
damages.

  Indemnification and Insurance. Under Section 145 of the Delaware General
Corporation Law, directors and officers as well as other employees and
individuals may be indemnified against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement in connection with specified
actions, suits or proceedings, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation--a
"derivative action") if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation, and with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard of
care is applicable in the case of the derivative actions, except that
indication only extends to expenses (including attorneys' fees) incurred in
connection with defense or settlement of such an action, and the Delaware
General Corporation Law requires court approval before there can be any
indemnification where the person seeking indemnification has been found liable
to the corporation.
 
  Section 7.7 of the Bylaws provides that the Company shall indemnify any
person to whom, and to the extent, indemnification may be granted pursuant to
Section 145 of the Delaware General Corporation law.
 
  Article Eleven of the Company Certificate provides that a person who was or
is made a party to, or is involved in, any action, suit or proceeding by
reason of the fact that he is or was a director, officer or employee of the
Company will be indemnified by the Company against all expenses and
liabilities, including counsel fees, reasonably incurred by or imposed upon
him, except in such cases where the director, officer or employee is adjudged
guilty of willful misconduct or malfeasance in the performance of his duties.
Article Eleven also provides that the right of indemnification shall be in
addition to and not exclusive of all other rights to which such director,
officer or employee may be entitled.

ITEM 17. UNDERTAKINGS
 
The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement:
 
      (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement;
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement;
 
  provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the registration statement is on Form S-3, Form S-8 or Form F-3, and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant
to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 

                                     II-3
<PAGE>
 
    (3) To remove from registration by means of a post-effective amendment
  any of the securities which remain unsold at the termination of the
  offering.
 
  (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
  (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.
 
  (d) The Company hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of Prospectus filed as part of
  this Registration Statement in reliance upon Rule 430A and contained in a
  form of Prospectus filed by the Registrants pursuant to Rule 424(b) (1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective; and
 
    (2) For purposes of determining any liability under the Securities Act of
  1933, each post-effective amendment that contains a form of Prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

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, the Depositor and the
Administrative Trustees are authorized to take any action, not inconsistent with
applicable law, the Certificate of Trust or this Trust Agreement, that each of
the Depositor and the Administrative Trustees determines in their discretion to
be necessary or desirable for such purposes, so long as such action does not
adversely affect in any material respect the interests of the Holders of the
Preferred Securities except as otherwise provided in Section 10.2(a).

                  SECTION 2.8.  Assets of Trust.  The assets of the
Trust shall consist of only the Trust Property.

                  SECTION 2.9. Title to Trust Property. Legal title to all Trust
Property shall be vested at all times in the Property Trustee (in its capacity
as such) and shall be held and administered by the Property Trustee for the
benefit of the Trust and the Securityholders in accordance with this Trust
Agreement. The Securityholder shall not have legal title to any part of the
assets of the Trust, but shall have an undivided beneficial interest in the
assets of the Trust.

                                PAYMENT ACCOUNT

                  SECTION 3.1. Payment Account. (a) On or prior to the Closing
Date, the Property Trustee shall establish the Payment Account. The Property
Trustee and any agent of the Property Trustee shall have exclusive control and
sole right of withdrawal with respect to the Payment Account for the purpose of
making deposits in and withdrawals from the Payment Account in accordance with
this Trust Agreement. All monies and other property deposited or held from time
to time in the Payment Account shall be held by the Property Trustee in the
Payment Account for the exclusive benefit of the Securityholders and for
distribution as herein provided,

                                      24

including (and subject to) any priority of payments provided for herein.

                  (b) The Property Trustee shall deposit in the Payment Account,
promptly upon receipt, all payments of principal of or interest on, and any
other payments or proceeds with respect to, the Debentures. Amounts held in the
Payment Account shall not be invested by the Property Trustee pending
distribution thereof.

                DISTRIBUTIONS; REDEMPTION; EXCHANGE; CONVERSION

                  SECTION 4.1. Distributions. (a) Distributions on the Trust
Securities shall be cumulative, and shall accrue from the date of original
issuance, or the most recent Distribution Date (as defined herein) and, except
in the event that the Depositor exercises its right to defer the payment of
interest on the Debentures pursuant to the Indenture, shall be payable quarterly
in arrears on March 1, June 1, September 1 and December 1 of each year,
commencing on March 1, 1997 (which dates correspond to the interest payment
dates on the Debentures), when, as and if available for payment by the Property
Trustee, as further described in paragraph (c) of this Section 4.1. If any date
on which Distributions are otherwise payable on the Trust Securities is not a
Business Day, then the payment of such Distributions shall be made on the next
succeeding day which is a Business Day (and no interest shall accrue for the
period from and after such date until the next succeeding Business Day) with the
same force and effect as if made on such date (each date on which Distributions
are payable in accordance with this Section 4.1(a), a "Distribution Date").

                  (b) The Trust Securities represent undivided beneficial
interests in the Trust Property, and the Distributions on the Trust Securities
shall be payable at a rate of 6 3/4% per annum of the Liquidation Amount of the
Trust Securities, such rate being the rate of interest payable on the Debentures
to be held by the Property Trustee. The amount of Distributions payable for any
period shall be computed on the basis of a 360-day year of twelve 30-day months.
For periods less than a full month, Distributions shall reflect interest on
Debentures computed on the basis of the actual number of elapsed days based on a
360-day

                                      25
<PAGE>
 
year. The amount of Distributions payable for any period shall include the
Additional Amounts, if any.

                  (c) 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.

                  (d) Distributions on the Trust Securities with respect to a
Distribution Date shall be payable to the Holders thereof as they appear on the
Securities Register for the Trust Securities on the relevant record date, which
shall be the date which is the fifteenth day (whether or not a Business Day)
next preceding such Distribution Date.

                  SECTION 4.2. Redemption. (a) (i) Upon an optional redemption
(as set forth in the Indenture) of Debentures, the proceeds from such redemption
shall be applied to redeem Trust Securities having an aggregate Liquidation
Amount equal to the aggregate principal amount of the Debentures so redeemed by
the Depositor, including pursuant to Section 4.4, at the Optional Redemption
Price, and upon a mandatory redemption (as set forth in the Indenture) of
Debentures, the proceeds from such redemption shall be applied to redeem Trust
Securities, having an aggregate Liquidation Amount equal to the aggregate
principal amount of the Debentures so redeemed by the Depositor, at the
Redemption Price.

                           (ii) If at any time following the Conversion
                  Expiration Date, less than five percent (5%) in principal
                  amount of the Debentures originally issued by the Depositor
                  remain outstanding, such Debentures are redeemable, at the
                  option of the Depositor, in whole but not in part, at a
                  redemption price equal to the aggregate principal amount
                  thereof, and all accrued and unpaid interest; in such event,
                  the proceeds from such redemption shall be applied to redeem
                  the Outstanding Trust Securities.

                  (b)  Notice of redemption (which notice will be
irrevocable) 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 the

                                                    26
<PAGE>
 
Depositor and each Holder of Trust Securities to be redeemed, at such Holder's
address as it appears in the Securities Register. All notices of redemption
shall state:

               (i)  the Redemption Date;

               (ii)  the Redemption Price or the Optional Redemption Price, as
          the case may be;

               (iii)  the CUSIP number;

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

               (v)  If the Preferred Securities are convertible, (A) that a
          Holder of Preferred Securities who desires to convert such Preferred
          Securities called for redemption must satisfy the requirements for
          conversion contained in Section 4.3 below, (B) the Conversion Price
          and (C), if previously determined, the Conversion Expiration Date;

               (vi)  that on the Redemption Date the Redemption Price or the
          Optional Redemption Price, as the case may be, 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

               (vii)  the place or places where such Trust Securities are to be
          surrendered for payment of the Redemption Price or the Optional
          Redemption Price, as the case may be.

          (c)  The Trust Securities redeemed on each Redemption Date
shall be redeemed at the Redemption Price or the Optional Redemption Price, as
the case may be, with the proceeds from the contemporaneous redemption of
Debentures. Redemptions of the Trust Securities shall be made and the Redemption
Price or the Optional Redemption Price, as the case may be, 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 or
the Optional Redemption Price, as the case may be.

                                      27
<PAGE>
 
                  (d) If the Property Trustee gives a notice of redemption in
respect of any Preferred Securities, then, by 12:00 noon, New York City time, on
the Redemption Date, subject to Section 4.2(c), the Property Trustee will, so
long as and to the extent the Preferred Securities are in book-entry-only form,
irrevocably deposit with the Clearing Agency for the Preferred Securities funds
sufficient to pay the applicable Redemption Price. If the Preferred Securities
are no longer in book-entry only form, the Property Trustee, subject to Section
4.2(c), will irrevocably deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price or Optional Redemption Price, as the case may
be, on such Preferred Securities held in certificated form and will give the
Paying Agent irrevocable instructions and authority to pay the Redemption Price
or the Optional Redemption Price, as the case may be, 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 Securities 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, upon the date of such deposit, all rights of Securityholders holding Trust
Securities so called for redemption will cease, except the right of such
Securityholders to receive the Redemption Price or the Optional Redemption
Price, as the case may be, but without interest, and such Trust Securities will
cease to be Outstanding. In the event that any date on which any Redemption
Price or the Optional Redemption Price, as the case may be, is payable is not a
Business Day, then payment of the Redemption Price or the Optional Redemption
Price, as the case may be, payable on such date will be made on the next
succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), with the same force and effect as if made
on such date.

                  (e) 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
that are to be redeemed. The particular Preferred Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Property Trustee from the Outstanding Preferred Securities

                                      28
<PAGE>
 
not previously called for redemption, by lot or by such other method as the
Property Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to $50 or an integral multiple of
$50 in excess thereof) of the liquidation amount of the Preferred Securities.
The Property Trustee shall promptly notify the Securities Registrar and the
Conversion Agent 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; it being understood that, in the
case of Preferred Securities registered in the name of and held of record by the
Clearing Agency (or any successor) or any nominee, the distribution of the
proceeds of such redemption will be made in accordance with the procedures of
the Clearing Agency or its nominee. 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 which has been or is to be redeemed. In the event
of any redemption in part, the Trust shall not be required to (i) issue,
register the transfer of or exchange of any Preferred Security during a period
beginning at the opening of business 15 days before any selection for redemption
of Preferred Securities and ending at the close of business on the earliest date
in which the relevant notice of redemption is deemed to have been given to all
holders of Preferred Securities to be so redeemed or (ii) register the transfer
of or exchange of any Preferred Securities so selected for redemption, in whole
or in part, except for the unredeemed portion of any Preferred Securities being
redeemed in part.

                  SECTION 4.3. Conversion. The Holders of Trust Securities,
subject to the limitations set forth in this Section, shall have the right at
any time prior to the Conversion Expiration Date, at their option, to cause the
Conversion Agent to convert Trust Securities, on behalf of the converting
Holders, into shares of Common Stock in the manner described herein on and
subject to the following terms and conditions:

                           (i) The Trust Securities will be convertible into
                  fully paid and nonassessable shares of Common Stock pursuant
                  to the Holder's direction to the Conversion Agent to exchange
                  such Trust Securities

                                      29
<PAGE>
 
                  for a portion of the Debentures, and immediately convert such
                  amount of Debentures into fully paid and nonassessable shares
                  of Common Stock at an initial rate of 2.6876 shares of Common
                  Stock for each Trust Security (which is equivalent to a
                  conversion price of $18.604 per $50 principal amount of
                  Debentures), subject to certain adjustments set forth in the
                  Indenture (as so adjusted, "Conversion Price").

                           (ii) In order to convert Trust Securities into Common
                  Stock, the Holder of such Trust Securities shall submit to the
                  Conversion Agent an irrevocable Notice of Conversion to
                  convert Trust Securities on behalf of such Holder, together,
                  if the Trust Securities are in certificated form, with such
                  certificates. The Notice of Conversion shall (i) set forth the
                  number of Trust Securities to be converted and the name or
                  names, if other than the Holder, in which the shares of Common
                  Stock should be issued and (ii) direct the Conversion Agent
                  (a) to exchange such Trust Securities for a portion of the
                  Debentures held by the Property Trustee (at the rate of
                  exchange specified in the preceding paragraph) and (b) to
                  immediately convert such Debentures, on behalf of such Holder,
                  into Common Stock (at the conversion rate specified in the
                  preceding paragraph). The Conversion Agent shall notify the
                  Property Trustee of the Holder's election to exchange Trust
                  Securities for a portion of the Debentures held by the
                  Property Trustee and the Property Trustee shall, upon receipt
                  of such notice, deliver to the Conversion Agent the
                  appropriate principal amount of Debentures for exchange in
                  accordance with this Section. The Conversion Agent shall
                  thereupon notify the Depositor of the Holder's election to
                  convert such Debentures into shares of Common Stock. Holders
                  of Trust Securities at the close of business on a Distribution
                  payment record date will be entitled to receive the
                  Distribution paid on such Trust Securities on the
                  corresponding Distribution Date notwithstanding the conversion
                  of such Trust Securities following such record date but prior
                  to such Distribution Date. Except as provided above, neither
                  the Trust nor the Depositor will make, or be required to make,
                  any payment, allowance or ad-

                                      30
<PAGE>
 
                  justment upon any conversion on account of any accumulated and
                  unpaid Distributions whether or not in arrears accrued on the
                  Trust Securities surrendered for conversion, or on account of
                  any accumulated and unpaid dividends on the shares of Common
                  Stock issued upon such conversion. Trust Securities shall be
                  deemed to have been converted immediately prior to the close
                  of business on the day on which an irrevocable Notice of
                  Conversion relating to such Trust Securities is received by
                  the Conversion Agent in accordance with the foregoing
                  provision (the "Conversion Date"). The Person or Persons
                  entitled to receive the Common Stock issuable upon conversion
                  of the Debentures shall be treated for all purposes as the
                  record holder or holders of such Common Stock on the date of
                  conversion. As promptly as practicable on or after the
                  Conversion Date, the Depositor shall issue and deliver at the
                  office of the Conversion Agent a certificate or certificates
                  for the number of full shares of Common Stock issuable upon
                  such conversion, together with the cash payment, if any, in
                  lieu of any fraction of any share to the Person or Persons
                  entitled to receive the same, unless otherwise directed by the
                  Holder in the notice of conversion and the Conversion Agent
                  shall distribute such certificate or certificates to such
                  Person or Persons.

                           (iii) On and after December 2, 1999, the Depositor
                  may, at its option, cause the conversion rights of holders of
                  the Debentures (and the corresponding conversion rights of
                  Holders of Trust Securities) to expire; provided, however,
                  that the Depositor may exercise this option only if for 20
                  trading days within any period of 30 consecutive trading days,
                  including the last trading day of such period, the Current
                  Market Price of Common Stock exceeds 120% of the Conversion
                  Price.

                           In order to exercise its option to terminate the
                  conversion rights of the Debentures, the Depositor must issue
                  a press release for publication on the Dow Jones News Service
                  announcing the Conversion Expiration Date prior to the opening
                  of business on the second trading day after any period in
                  which the condition in the preceding sen

                                      31
<PAGE>
 
                  tence has been met, but in no event prior to December 2, 1999.
                  The press release shall announce the Conversion Expiration
                  Date (which may not occur sooner than 30 nor more than 60 days
                  after the Depositor issues the press release announcing its
                  intention to terminate the conversion rights of the
                  Debentures) and provide the current Conversion Price and
                  Current Market Price of Common Stock, in each case as of the
                  close of business on the trading day next preceding the date
                  of the press release. Conversion rights will terminate at the
                  close of business on the Conversion Expiration Date.

                           The Depositor, or at the request of the Depositor,
                  the Property Trustee shall send notice of the expiration of
                  conversion rights by first-class mail to the Holders of the
                  Trust Securities and the holders of the Debentures not more
                  than four Business Days after the Depositor issues the press
                  release or, if the Property Trustee is requested to send such
                  notice, which shall be on the date of such press release,
                  after the Depositor delivers written instructions to the
                  Property Trustee containing the information required by the
                  next sentence to be in the notice. Such mailed notice of the
                  expiration of the conversion rights of the Holders shall
                  state: (A) the Conversion Expiration Date; (B) the Conversion
                  Price of the Trust Securities and the Current Market Price of
                  the Common Stock, in each case as of the close of business on
                  the Business Day next preceding the date of the notice of
                  expiration of the conversion rights of the Holders; (C) the
                  place or places at which Trust Securities may be surrendered
                  prior to the Conversion Expiration Date for certificates
                  representing shares of Common Stock; and (D) such other
                  information or instructions as the Depositor deems necessary
                  or advisable to enable a Holder to exercise its conversion
                  right hereunder. No defect in the notice of expiration of the
                  conversion rights of the Holders or in the mailing thereof
                  with respect to any Trust Security shall affect
                  the validity of such notice with respect to any other Trust
                  Security. As of the close of business on the Conversion
                  Expiration Date, the Debentures (and correspondingly, the
                  Trust Securities) shall 

                                      32
<PAGE>
 
                  no longer be convertible into Common Stock. In the event that
                  the Depositor does not exercise its option to terminate the
                  conversion rights of the Debentures, the Conversion Expiration
                  Date with respect to the Trust Securities will be the close of
                  business two Business Days preceding the date set for
                  redemption of the Trust Securities upon the mandatory or
                  optional redemption of the Debentures.

                           (iv) Each Holder of a Trust Security by its
                  acceptance thereof initially appoints IBJ Schroder Bank &
                  Trust Company not in its individual capacity but solely as
                  conversion agent (the "Conversion Agent") for the purpose of
                  effecting the conversion of Trust Securities in accordance
                  with this Section. In effecting the conversion and
                  transactions described in this Section, the Conversion Agent
                  shall be acting as agent of the Holders of Trust Securities
                  directing it to effect such conversion transactions. The
                  Conversion Agent is hereby authorized (i) to exchange Trust
                  Securities from time to time for Debentures held by the Trust
                  in connection with the conversion of such Trust Securities in
                  accordance with this Section and (ii) to convert all or a
                  portion of the Debentures into Common Stock and thereupon to
                  deliver such shares of Common Stock in accordance with the
                  provisions of this Section and to deliver to the Property
                  Trustee any new Debenture or Debentures for any resulting
                  unconverted principal amount delivered to the Conversion Agent
                  by the Debenture Trustee.

                           (v) No fractional shares of Common Stock will be
                  issued as a result of conversion, but, in lieu thereof, such
                  fractional interest will be paid in cash by the Depositor to
                  the Conversion Agent in an amount equal to the Current Market
                  Price of the fractional share of the Common Stock, and the
                  Conversion Agent will in turn make such payment to the Holder
                  or Holders of Trust Securities so converted.

                           (vi) Nothing in this Section 4.3 shall limit the
                  requirement of the Trust to withhold taxes pursuant to the
                  terms of the Trust Securities or

                                      33

                  as set forth in this Agreement or otherwise required of the
                  Property Trustee or the Trust to pay any amounts on account of
                  such withholdings.

                  SECTION 4.4. Special Event Exchange or Redemption. (a) If a
Special Event shall occur and be continuing, the Property Trustee shall direct
the Conversion Agent to exchange all Outstanding Trust Securities for Debentures
having a principal amount equal to the aggregate Liquidation Amount of the Trust
Securities to be exchanged and with accrued interest in an amount equal to any
unpaid Distribution (including any Additional Amounts) on the Trust Securities;
provided, however, that, in the case of a Tax Event, the Depositor shall have
the right to (i) direct that less than all, or none, as appropriate, of the
Trust Securities be so exchanged if and for so long as the Depositor shall have
elected to pay any Additional Sums (as defined in the Indenture) such that the
amount received by Holders of Trust Securities not so exchanged in respect of
Distributions and other distributions are not reduced as a result of such Tax
Event, and shall not have revoked any such election or failed to make such
payments or (ii) cause the Trust Securities to be redeemed in the manner set
forth below. If a Tax Event shall occur or 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 upon the later of (i) 90 days
following the occurrence of such Tax Event or (ii) December 2, 1999. Promptly
following such redemption, Trust Securities with an aggregate liquidation amount
equal to the aggregate principal amount of the Debentures so redeemed will be
redeemed by the Trust at the Optional Redemption Price on a pro rata basis.

                  (b) Notice of any exchange pursuant to this Section 4.4 (an
"Exchange Notice") of the Trust Securities, which Exchange Notice shall be
irrevocable, will be given by the Property Trustee by first-class mail to the
Depositor and to each record Holder of Trust Securities to be exchanged not
fewer than 30 nor more than 60 days prior to the date fixed for exchange
thereof. For purposes of the calculation of the date of exchange and the dates
on which notices are given pursuant to this paragraph (b), an Exchange Notice
shall be deemed to be given on the day such notice is first mailed by
first-class mail, postage prepaid, to each Holder. Each Exchange Notice shall be
addressed to each Holder of Trust Securities at the address of such Holder
appearing in the books and records of the Trust. Each Ex-

                                      34
<PAGE>
 
change Notice shall state: (A) the exchange date; (B) the aggregate Liquidation
Amount and any unpaid Distributions (including any Additional Amounts) on the
Trust Securities to be exchanged and the aggregate principal amount and any
accrued interest on the Debentures to be exchanged therefor; (C) that on the
exchange date the Trust Securities to be so exchanged shall be exchanged for
Debentures and that Distributions on the Trust Securities so exchanged will
cease to accumulate on and after said date; and (D) the identity of the
Conversion Agent, if any, and the place or places where each Trust Certificate
to be exchanged is to be surrendered in exchange for Debentures. No defect in
the Exchange Notice or in the mailing thereof with respect to any Trust Security
shall affect the validity of the exchange proceedings for any other Trust
Security.

                  (c) In the event that fewer than all the Outstanding Preferred
Securities are to be exchanged, then, on the exchange date, (i) if all of the
Outstanding Preferred Securities are represented by Definitive Preferred
Securities Certificates, the particular Preferred Securities to be exchanged
will be selected by the Property Trustee from the Outstanding Preferred
Securities not previously called for redemption or exchange on a pro rata basis,
(ii) if all of the Outstanding Preferred Securities are represented by
Book-Entry Preferred Securities Certificates, the Property Trustee shall provide
for the selection for exchange of a portion of the Global Certificate
representing the Book-Entry Preferred Securities Certificates on a pro rata
basis and (iii) if Outstanding Trust Securities are represented by both
Definitive Preferred Securities Certificates and Book-Entry Preferred Securities
Certificates, the Property Trustee shall select the portion of the Global
Certificate representing the Book-Entry Preferred Securities Certificates and
the particular Outstanding Preferred Securities represented by Definitive
Preferred Securities Certificates to be exchanged on a pro rata basis. In the
case of clause (ii) or (iii) above, the particular Book-Entry Preferred
Securities Certificates to be exchanged shall be selected in accordance with the
applicable rules and procedures for the Clearing Agency in whose name, or whose
nominee's name, such global certificate is then held. Any Preferred Securities
Certificate that is to be exchanged only in part shall be surrendered with due
endorsement or by a written instrument of transfer fully executed by the Holder
thereof (or its attorney duly authorized in writing) and the Trust shall prepare
and deliver to such Holder, without service charge, a new

                                      35
<PAGE>
 
Preferred Securities Certificate or Certificates in aggregate stated Liquidation
Amount equal to, and in exchange for, the unredeemed portion of the Preferred
Securities Certificate so surrendered. The Common Securities shall be exchanged
in a similar manner.

                  (d) In the event of an exchange pursuant to this Section 4.4,
on the date fixed for any such exchange, (i) if the Preferred Securities are
represented by Book-Entry Preferred Securities Certificates, the Clearing Agency
of its nominee, as the record Holder of the Preferred Securities, will exchange
through the Conversion Agent the Global Certificate representing the Preferred
Securities to be exchanged for a registered Global Certificate or certificates
representing the Debentures to be delivered upon such exchange, (ii) if the
Preferred Securities are represented by Definitive Preferred Securities
Certificates, the certificates representing the Preferred Securities to be so
exchanged will be deemed to represent Debentures having a principal amount equal
to the aggregate stated Liquidation Amount of such Preferred Securities until
such certificates are presented to the Conversion Agent for exchange for
definitive certificates representing Debentures and (iii) all rights of the
Holders of the Preferred Securities so exchanged will cease, except for the
right of such Holders to receive Debentures. The Common Securities shall be
exchanged in a similar manner

                  (e) Each Holder, by becoming a party to this Agreement
pursuant to Section 10.11 of this Agreement, will be deemed to have agreed to be
bound by these exchange provisions in regard to the exchange of Trust Securities
for Debentures pursuant to the terms described above.

                  (f) Nothing in this Section 4.4 shall limit the requirement of
the Trust to withhold taxes pursuant to the terms of the Trust Securities or as
set forth in this Agreement or otherwise require the Property Trustee or the
Trust to pay any amounts on account of such withholdings.

                  SECTION 4.5. Subordination of Common Securities. Payment of
Distributions (including Additional Amounts, if applicable) on, and the
Redemption Price of, the Trust Securities, as applicable, shall be made pro
rata based on the Liquidation Amount of the Trust Securities; provided, however,
that if on any Distribution Date or Redemption Date an Event of Default shall
have occurred and be continuing, no

                                      36
<PAGE>
 
payment of any Distribution (including Additional Amounts, if applicable) on, or
the Redemption Price of, any Common Security, and no other payment on account of
the redemption, liquidation or other acquisition of Common Securities, shall be
made unless payment in full in cash of all accumulated and unpaid Distributions
(including Additional Amounts, if applicable) on all Outstanding Preferred
Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities, shall have been made or provided
for, and all funds immediately available to the Property Trustee shall first be
applied to the payment in full in cash of all Distributions (including
Additional Amounts, if applicable) on, or the Redemption Price of, Preferred
Securities then due and payable.

                  SECTION 4.6. 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, in accordance
with the Certificate Depositary Agreement 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 4.7. Tax Returns and Reports. The Administrative
Trustees 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 Administrative Trustees shall (a) prepare and file (or cause to be prepared
or filed) Form 1041 or 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
Securityholder a Form 1099 or the appropriate Internal Revenue Service form
required to be furnished to such Securityholder or the information required to
be provided on such form. The Administrative Trustees shall provide the
Depositor and the Property Trustee with a copy of all such returns, reports and
schedules promptly after such filing or furnishing. The Trustees shall comply
with United States Federal withholding and backup withhold-

                                      37
<PAGE>
 
ing tax laws and information reporting requirements with respect to any payments
to Securityholders under the Trust Securities.

                  SECTION 4.8. Payment of Taxes, Duties, Etc. of the Trust. Upon
receipt under the Debentures of Additional Sums, the Property Trustee, upon
receipt of written notice from the Depositor or the Administrative Trustees,
shall promptly pay from such Additional Sums any taxes, duties or governmental
charges of whatsoever nature (other than withholding taxes) imposed on the Trust
by the United States or any other taxing authority.

                  SECTION 4.9. Payments under Indenture. Any amount payable
hereunder to any Holder of Preferred Securities (and any Owner with respect
thereto) shall be reduced by the amount of any corresponding payment such Holder
(or Owner) has directly received pursuant to Section 5.8 of the Indenture in
accordance with the terms of Section 6.8 hereof.

                                   ARTICLE 5

                         TRUST SECURITIES CERTIFICATES

                  SECTION 5.1. Initial Ownership. Upon the formation of the
Trust and until the issuance of the Trust Securities, and at any time during
which no Trust Securities are Outstanding, the Depositor shall be the sole
beneficial owner of the Trust.

                  SECTION 5.2. The Trust Securities Certificates. The Preferred
Securities Certificates shall be issued in minimum denominations of $50
Liquidation Amount and integral multiples of $50 in excess thereof, and the
Common Securities Certificates shall be issued in denominations of $50
Liquidation Amount and integral multiples thereof. The consideration received by
the Trust for the issuance of the Trust Securities shall constitute a
contribution to the capital of the Trust and shall not constitute a loan to the
Trust. Preferred Securities initially sold to qualified institutional buyers in
reliance on Rule 144A under the Securities Act ("Rule 144A Preferred
Securities") initially will be represented by one or more certificates in regis-
tered, global form (collectively, the "Restricted Global Certificate").
Preferred Securities initially sold in off-shore transactions in reliance on
Regulation S ("Regulation 

                                      38
<PAGE>
 
S Preferred Securities") initially will be represented by one or more
certificates in registered, global form (collectively, the "Regulation S Global
Certificate" and, together with the Restricted Global Certificate, the "Global
Certificates"). Preferred Securities initially transferred, in accordance with
Section 5.4, to institutional accredited investors in a manner exempt from the
registration requirements of the Securities Act will be exchanged for Preferred
Securities in registered, certificated form (the "Certificated Preferred
Securities"). The Trust Securities Certificates shall be executed on behalf of
the Trust by manual or facsimile signature of at least one Administrative
Trustee and authenticated by the Property Trustee. Trust Securities Certificates
bearing the manual or facsimile 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 benefit 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 Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Section 5.4.

                  SECTION 5.3. Delivery of Trust Securities Certificates. On the
Closing Date, the Administrative Trustees shall cause Trust Securities
Certificates, in an aggregate Liquidation Amount as provided in Sections 2.4 and
2.5, to be executed on behalf of the Trust and delivered to or upon the written
order of the Depositor, signed by its Chairman of the Board, any Vice Chairman,
its President, any Senior Vice President or any Vice President, Treasurer or
Assistant Treasurer or Controller without further corporate action by the
Depositor, in authorized denominations.

                  A Trust Security Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the Property
Trustee. The signature shall be conclusive evidence that the Trust Security
Certificate has been authenticated under this Trust Agreement. Upon a writ-
ten order of the Trust signed by one Administrative Trustee, the Property
Trustee shall authenticate the Trust Security Certificates for original issue.

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

                  SECTION 5.4. Registration of Transfer and Exchange of
Preferred Securities; Restrictions on Transfer. (a) The Securities Registrar
shall keep or cause to be kept, at the office or agency maintained pursuant to
Section 5.8, a Securities Register in which, subject to such reasonable
regulations as it may prescribe, the Securities Registrar shall provide for the
registration of Preferred Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Preferred
Securities Certificates as herein provided. The Property Trustee shall be the
initial Securities Registrar.

                  Subject to the other provisions of this Trust Agreement
regarding restrictions on transfer, upon surrender for registration of transfer
of any Preferred Security at an office or agency of the Depositor designated
pursuant to Section 5.8 for such purpose, the Depositor shall execute, and the
Property Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Preferred Securities of any
authorized denominations and of a like aggregate principal amount and bearing
such restrictive legends as may be required by this Trust Agreement.

                  At the option of the Holder, and subject to the other
provisions of this Section 5.4, Preferred Securities may be exchanged for other
Preferred Securities of any authorized denomination and of a like Liquidation
Amount, upon surrender of the Preferred Securities to be exchanged at any such
office or agency. Whenever any Preferred Securities are so surrendered for
exchange, the Depositor shall execute, and the Property Trustee shall
authenticate and deliver, the Preferred Securities which the Holder making the
exchange is entitled to receive.

                                      40
<PAGE>
 
                  All Preferred Securities issued upon any registration of
transfer or exchange of Preferred Securities shall be the valid obligations of
the Depositor, evidencing the same debt, and entitled to the same benefits under
this Trust Agreement, as the Securities surrendered upon such registration of
transfer or exchange.

                  Every Preferred Security presented or surrendered for
registration of transfer or for exchange shall (if so requested by the Depositor
or the Securities Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Depositor and the Securities
Registrar duly executed, by the Holder thereof or his attorney duly authorized
in writing.

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

                  (b) Certain Transfers and Exchanges. Notwithstanding any other
provision of this Trust Agreement or the Preferred Securities, transfers and
exchanges of Preferred Securities and beneficial interests in a Global
Certificate of the kinds specified in this Section 5.4(b) shall be made only in
accordance with this Section 5.4(b).

                           (i) Restricted Global Certificate to Regulation S
         Global Certificate. If the owner of a beneficial interest in the
         Restricted Global Certificate wishes at any time to transfer such
         interest to a Person who wishes to acquire the same in the form of a
         beneficial interest in the Regulation S Global Certificate, such
         transfer may be effected in accordance with the provisions of this
         Clause (b)(i) and Clause (b)(vii) below and subject to the Applicable
         Procedures. Upon receipt by the Property Trustee, as Securities
         Registrar, of (A) an order given by the Clearing Agency or its
         authorized representative directing that a beneficial interest in the
         Regulation S Global Certificate in a specified principal amount be
         credited to a specified participant's account and that a beneficial
         interest in the Restricted Global Certificate in an equal principal
         amount be debited from another specified participant's account and (B)
         a Regulation S Cer-

                                      41
<PAGE>
 
         tificate, satisfactory to the Property Trustee and duly executed by
         the owner of such beneficial interest in the Restricted Global
         Certificate or his attorney duly authorized in writing, then the
         Property Trustee, as Securities Registrar but subject to Clause
         (b)(vii) below, shall reduce the share number of the Restricted Global
         Certificate and increase the share number of the Regulation S Global
         Certificate by such specified principal amount as provided in Section
         5.11(b).

                           (ii) Regulation S Global Certificate to Restricted
         Global Certificate. If the owner of a beneficial interest in the
         Regulation S Global Certificate wishes at any time to transfer such
         interest to a Person who wishes to acquire the same in the form of a
         beneficial interest in the Restricted Global Certificate, such transfer
         may be effected only in accordance with this Clause (b)(ii) and subject
         to the Applicable Procedures. Upon receipt by the Property Trustee, as
         Securities Registrar, of (A) an order given by the Clearing Agency or
         its authorized representative directing that a beneficial interest in
         the Restricted Global Certificate in a specified principal amount be
         credited to a specified participant's account and that a beneficial
         interest in the Regulation S Global Certificate in an equal principal
         amount be debited from another specified participant's account and (B)
         if such transfer is to occur during the Restricted Period, a Restricted
         Securities Certificate, satisfactory to the Property Trustee and duly
         executed by the owner of such beneficial interest in the Regulation S
         Global Certificate or his attorney duly authorized in writing, then the
         Property Trustee, as Securities Registrar, shall reduce the principal
         amount of the Regulation S Global Certificate and increase the
         principal amount of the Restricted Global Certificate by such specified
         principal amount as provided in Section 5.11(b).

                           (iii)  Restricted Non-Global Certificate to
         Restricted Global Certificate or Regulation S Global Certificate. If
         the Holder of a Restricted Security (other than a Global Certificate)
         wishes at any time to transfer all or any portion of such Restricted
         Security to a Person who wishes to take delivery thereof in the form of
         a beneficial interest in the Restricted Global Certificate or the
         Regulation S Global Certificate, such transfer may be effected only in
         accordance with

                                      42
<PAGE>
 
         the provisions of this Clause (b)(iii) and Clause (b)(vii) below and
         subject to the Applicable Procedures. Upon receipt by the Property
         Trustee, as Securities Registrar, of (A) such Restricted Security as
         provided in Section 5.4(a) and instructions satisfactory to the
         Property Trustee directing that a beneficial interest in the Restricted
         Global Certificate or Regulation S Global Certificate in a specified
         principal amount not greater than the share amount of such Preferred
         Security be credited to a specified participant's account and (B) a
         Restricted Securities Certificate, if the specified account is to be
         credited with a beneficial interest in the Restricted Global
         Certificate, or a Regulation S Certificate, if the specified account is
         to be credited with a beneficial interest in the Regulation S Global
         Certificate, in either case satisfactory to the Property Trustee and
         duly executed by such Holder or his attorney duly authorized in
         writing, then the Property Trustee, as Securities Registrar but subject
         to Clause (b)(vii) below, shall cancel such Restricted Security (and
         issue a new Restricted Security in respect of any untransferred portion
         thereof) as provided in Section 5.4(a) and increase the principal
         amount of the Restricted Global Certificate or the Regulation S Global
         Certificate, as the case may be, by the specified principal amount as
         provided in Section 5.11(b).

                           (iv) Regulation S Non-Global Certificate to
         Restricted Global Certificate or Regulation S Global Certificate. If
         the Holder of a Regulation S Preferred Security (other than a Global
         Certificate) wishes at any time to transfer all or any portion of such
         Regulation S Security to a Person who wishes to acquire the same in the
         form of a beneficial interest in the Restricted Global Certificate or
         the Regulation S Global Certificate, such transfer may be effected only
         in accordance with this Clause (b)(iv) and Clause (b)(vii) below and
         subject to the Applicable Procedures. Upon receipt by the Property
         Trustee, as Securities Registrar, of (A) such Regulation S Security as
         provided in Section 5.4(a) and instructions satisfactory to the
         Property Trustee directing that a beneficial interest in the Restricted
         Global Certificate or Regulation S Global Certificate in a specified
         share amount not greater than the share amount of such Preferred
         Security be credited to a specified participant's account and

                                      43
<PAGE>
 
         (B) if the transfer is to occur during the Restricted Period and the
         specified account is to be credited with a beneficial interest in the
         Restricted Global Certificate, a Restricted Securities Certificate
         satisfactory to the Property Trustee and duly executed by such Holder
         or his attorney duly authorized in writing then the Property Trustee,
         as Securities Registrar but subject to Clause (b)(vii) below, shall
         cancel such Regulation S Security (and issue a new Regulation S
         Security in respect of any untransferred portion thereof) as provided
         in Section 5.4(a) and increase the principal amount of the Restricted
         Global Certificate or the Regulation S Global Certificate, as the case
         may be, by the specified principal amount as provided in Section
         5.11(b).

                           (v) Non-Global Certificate to Non-Global Certificate.
         A Security that is not a Global Certificate may be transferred, in
         whole or in part, to a Person who takes delivery in the form of another
         Security that is not a Global Certificate as provided in Section 5.11,
         provided that, if the Security to be transferred in whole or in part is
         a Restricted Security, or is a Regulation S Preferred Security and the
         transfer is to occur during the Restricted Period, then the Property
         Trustee shall have received (A) a Restricted Securities Certificate,
         satisfactory to the Property Trustee and duly executed by the
         transferor Holder or his attorney duly authorized in writing, in which
         case the transferee Holder shall take delivery in the form of a
         Restricted Security, or (B) a Regulation S Certificate, satisfactory to
         the Property Trustee and duly executed by the transferor Holder or his
         attorney duly authorized in writing, in which case the transferee
         Holder shall take delivery in the form of a Regulation S Preferred
         Security (subject in every case to Section 5.4(c)).

                           (vi)  Exchanges between Global Certificate
         and Non-Global Certificate. A beneficial interest in a Global
         Certificate may be exchanged for a Preferred Security that is not a
         Global Certificate as provided in Section 5.11 to an institution that
         is an accredited investor within the meaning of Rule 501(a)(1), (2),
         (3) or (7) of Regulation D of the Securities Act of 1933, as amended,
         provided that, if such interest is a beneficial interest in the
         Restricted Global Certificate,

                                      44
<PAGE>
 
         or if such interest is a beneficial interest in the Regulation S Global
         Certificate and such exchange is to occur during the Restricted Period,
         then such interest shall be exchanged for a Restricted Security
         (subject in each case to Section 5.4(c)). A Preferred Security that is
         not a Global Certificate may be exchanged for a beneficial interest in
         a Global Certificate only if (A) such exchange occurs in connection
         with a transfer effected in accordance with Clause (b)(iii) or (iv)
         above or (B) such Security is a Regulation S Preferred Security and
         such exchange occurs after the Restricted Period.

                           (vii) Regulation S Global Certificate to be Held
         Through Euroclear or Cedel during Restricted Period. The Depositor
         shall use its best efforts to cause the Clearing Agency to ensure that,
         until the expiration of the Restricted Period, beneficial interests in
         the Regulation S Global Certificate may be held only in or through
         accounts maintained at the Clearing Agency by Euroclear or Cedel (or by
         participants acting for the account thereof), and no person shall be
         entitled to effect any transfer or exchange that would result in any
         such interest being held otherwise than in or through such an account;
         provided that this Clause (b)(vii) shall not prohibit any transfer or
         exchange of such an interest in accordance with Clause (b)(ii) or (vi)
         above.

                  (c) Securities Act Legends. Rule 144A Securities, Certificated
Preferred Securities and their respective Successor Securities shall bear a
Restricted Securities Legend as set forth in Section 5.15, and the Regulation S
Preferred Securities and their Successor Securities shall bear a Regulation S
Legend, subject to the following:

                           (i) subject to the following Clauses of this Section
         5.4(c), a Preferred Security or any portion thereof which is exchanged,
         upon transfer or otherwise, for a Global Certificate or any portion
         thereof shall bear the Securities Act Legend borne by such Global
         Certificate while represented thereby;

                           (ii) subject to the following Clauses of this Section
         5.4(c), a new Preferred Security which is not a Global Certificate and
         is issued in exchange for another Preferred Security (including,a
         Global Certifi-

<PAGE>
 
         cate) or any portion thereof, upon transfer or otherwise, shall bear
         the Securities Act Legend borne by such other Preferred Security,
         provided that, if such new Preferred Security is required pursuant to
         Section 5.4(b)(v) or (vi) to be issued in the form of a Restricted
         Security, it shall bear a Restricted Securities Legend and, if such new
         Preferred Security is so required to be issued in the form of a
         Regulation S Preferred Security, it shall bear a Regulation S Legend;

                           (iii) Any Preferred Securities which are sold or
         otherwise disposed of pursuant to an effective registration statement
         under the Securities Act (including the Shelf Registration Statement),
         together with their Successor Securities shall not bear a Securities
         Act Legend; the Depositor shall inform the Property Trustee in writing
         of the effective date of any such registration statement registering
         the Preferred Securities under the Securities Act and shall notify the
         Property Trustee at any time when prospectuses may not be delivered
         with respect to Preferred Securities to be sold pursuant to such
         registration statement. The Property Trustee shall not be liable for
         any action taken or omitted to be taken by it in good faith in
         accordance with the aforementioned registration statement;

                           (iv) at any time after the Preferred Securities may
         be freely transferred without registration under the Securities Act or
         without being subject to transfer restrictions pursuant to the
         Securities Act, a new Preferred Security which does not bear a
         Securities Act Legend may be issued in exchange for or in lieu of a
         Preferred Security (other than a Global Certificate) or any portion
         thereof which bears such a legend if the Property Trustee has received
         an Unrestricted Securities Certificate, satisfactory to the Property
         Trustee and duly executed by the Holder of such legended Preferred
         Security or his attorney duly authorized in writing, and after such
         date and receipt of such certificate, the Property Trustee shall
         authenticate and deliver such a new Preferred Security in exchange for
         or in lieu of such other Preferred Security as provided in this 
         Article 5;

                                      46
<PAGE>
 
                           (v) a new Preferred Security which does not bear a
         Securities Act Legend may be issued in exchange for or in lieu of a
         Preferred Security (other than a Global Certificate) or any portion
         thereof which bears such a legend if, in the Depositor's judgment,
         placing such a legend upon such new Preferred Security is not necessary
         to ensure compliance with the registration requirements of the
         Securities Act, and the Property Trustee, at the direction of the
         Depositor, shall authenticate and deliver such a new Preferred Security
         as provided in this Article 5; and

                           (vi) notwithstanding the foregoing provisions of this
         Section 5.4(c), a Successor Security of a Preferred Securities that
         does not bear a particular form of Securities Act Legend shall not bear
         such form of legend unless the Depositor has reasonable cause to
         believe that such Successor Security is a "restricted security" within
         the meaning of Rule 144, in which case the Property Trustee, at the
         direction of the Depositor, shall authenticate and deliver a new
         Preferred Security bearing a Restricted Securities Legend in exchange
         for such Successor Security as provided in this Article 5.

                  SECTION 5.5. 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, loss or theft of any
Trust Securities Certificate and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees 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 Administrative Trustees, or any one of them, on behalf of the
Trust shall execute and make available for authentication and 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 denomination.
In connection with the issuance of any new Trust Securities Certificate under
this Section, 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 duplicative Trust Securities Certificate issued
pursuant to this Section shall

                                      47
<PAGE>
 
constitute conclusive evidence of an undivided beneficial interest
in the assets of the Trust, as if originally issued, whether or not the lost,
stolen or destroyed Trust Securities Certificate shall be found at any time.

                  SECTION 5.6. Persons Deemed Securityholders. The Property
Trustee and the Securities Registrar shall treat the Person in whose name any
Trust Securities Certificate shall be registered in the Securities Register as
the owner of such Trust Securities Certificate for the purpose of receiving
Distributions and for all other purposes whatsoev-er, and neither the Property
Trustee nor the Securities Registrar shall be bound by any notice to the
contrary.

                  SECTION 5.7. Access to List of Securityholders' Names and
Addresses. The Administrative Trustees or the Depositor shall furnish or cause
to be furnished (unless the Property Trustee is acting as Securities Registrar
with respect to the Trust Securities under the Trust Agreement) a list, in such
form as the Property Trustee may reasonably require, of the names and addresses
of the Securityholders as of the most recent record date (a) to the Property
Trustee, quarterly at least 5 Business Days before each Distribution Date, and
(b) to the Property Trustee, promptly after receipt by the Depositor of a
request therefor from the Property Trustee 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
Administrative Trustees 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 Securityholders to communicate
with other Securityholders with respect to their rights under this Trust
Agreement or under the Trust Securities, and the corresponding rights of the
Trustee shall be as provided in the Trust Indenture Act, except to the extent
Section 3819 of the Delaware Business Trust Act would require greater access to
such information, in which case the latter shall apply. 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
Administrative Trustees accountable by reason of the disclosure of its name and
address, regardless of the source from which such information was derived.

                                      48

                  SECTION 5.8. Maintenance of Office or Agency. The Securities
Registrar shall maintain in The City of New York an office or offices or agency
or agencies where Preferred Securities Certificates may be surrendered for
registration of transfer, exchange or conversion and where notices and demands
to or upon the Trustees in respect of the Trust Securities Certificates may be
served. The Securities Registrar initially designates One State Street, 11th
Floor, New York, New York 10004, Attention: Corporate Trust Department, as its
principal corporate trust office for such purposes. The Securities Registrar
shall give prompt written notice to the Depositor and to the Securityholders of
any change in the location of the Securities Register or any such office or
agency.

                  SECTION 5.9. Appointment of Paying Agent. In the event that
the Preferred Securities are not in book-entry form only, the Trust shall
maintain in the Borough of Man-hattan, City of New York, an office or agency
(the "Paying Agent") where the Preferred Securities may be presented for
payment. The Paying Agent shall make Distributions to Securityholders from the
Payment Account and shall report the amounts of such Distributions to the
Property Trustee and the Administrative Trustees. 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 Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Property Trustee, and any co-paying agent chosen by the
Property Trustee and acceptable to the Administrative Trustees and the
Depositor. 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 Property Trustee shall no longer be the Paying
Agent or a successor Paying Agent shall resign or its authority to act be
revoked, the Administrative Trustees shall appoint a successor that is
acceptable to the Property Trustee and the Depositor to act as Paying Agent
(which shall be a bank or trust company). Each successor Paying Agent or any
additional Paying Agent shall agree with the Trustees that, as Paying Agent,
such successor Paying Agent or additional Paying Agent will hold all sums, if
any, held by it for payment to the Securityholders in trust for the benefit of
the Securityholders entitled thereto until

                                      49
<PAGE>
 
such sums shall be paid to each Securityholder. 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 shall apply to the Property
Trustee also in its role as Paying Agent, for so long as the Property Trustee
shall act as Paying Agent and, 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 5.10. Ownership of Common Securities by Depositor. On
the Closing Date provided for in Section 2.5, the Depositor shall acquire and
retain beneficial and record ownership of the Common Securities. To the fullest
extent permitted by law, any attempted transfer of the Common Securities shall
be void. The Administrative Trustees shall cause each Common Securities
Certificate issued to the Depositor to contain a legend stating "THIS
CERTIFICATE IS NOT TRANSFERABLE".

                  SECTION 5.11. Global Securities; Non-Global Securities; Common
Securities Certificate. (a) Each Global Certificate authenticated under this
Trust Agreement shall be registered in the name of the Clearing Agency
designated by the Depositor for such Global Certificate or a nominee thereof and
delivered to such Clearing Agency or a nominee thereof or custodian therefor,
and each such Global Certificate shall constitute a Preferred Security for all
purposes of this Trust Agreement.

                  (b) If a Global Certificate is to be exchanged for
Certificated Preferred Securities or canceled in whole, it shall be surrendered
by or on behalf of the Clearing Agency, its nominee or custodian to the Property
Trustee, as Securities Registrar, for exchange or cancellation as provided in
this Article 5. If any Global Certificate is to be exchanged for Certificated
Preferred Securities or cancelled in part, or if another Preferred Security is
to be exchanged in whole or in part for a beneficial interest in any Global
Certificate, in each case, as provided in Section 5.4, then either (i) such
Global Certificate shall be so surrendered for exchange or cancellation as
provided in this Article 5 or (ii) the principal amount thereof shall be reduced
or increased by an amount equal to the portion thereof to be so exchanged or
cancelled, or equal to the principal amount of

                                      50
<PAGE>
 
such Certificated Preferred Security to be so exchanged for a beneficial
interest therein, as the case may be, by means of an appropriate adjustment made
on the records of the Property Trustee, as 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 any such surrender or adjustment of a Global
Certificate, the Property Trustee shall, subject to Section 5.4 and as otherwise
provided in this Article 5, authenticate and deliver any Preferred Securities
issuable in exchange for such Global Certificate (or any portion thereof) to or
upon the order of, and registered in such names as may be directed by, the
Clearing Agency or its authorized representative. Upon the request of the
Property Trustee in connection with the occurrence of any of the events
specified in the preceding paragraph, the Depositor shall promptly make
available to the Property Trustee a reasonable supply of Preferred Securities
that are not in the form of Global Certificates. The Property Trustee shall be
entitled to rely upon any order, direction or request of the Clearing Agency or
its authorized representative which is given or made pursuant to this Article 5
if such order, direction or request is given or made in accordance with the
Applicable Procedures.

                  (c) Every Preferred Security authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global
Certificate or any portion thereof, whether pursuant to this Article 5 or
otherwise, shall be authenticated and delivered in the form of, and shall be, a
Global Certificate, unless such Preferred Security is registered in the name of
a Person other than the Clearing Agency for such Global Certificate or a nominee
thereof.

                  (d) The Clearing Agency or its nominee, as registered owner of
a Global Certificate, shall be the holder of such Global Certificate for all
purposes under the Trust Agreement and the Preferred Securities, and owners of
beneficial interests in a Global Certificate shall hold such interests pursuant
to the Applicable Procedures. Accordingly, any such Owner's beneficial interest
in a Global Certificate will be shown only on, and the transfer of such interest
shall be effected only through, records maintained by the Clearing Agency or its
nominee or its participants and such owners of beneficial interests in a Global
Certifi-

                                      51
<PAGE>
 
cate will not be considered the owners or holders of such Global Certificate for
any purpose of this Trust Agreement or the Preferred Securities.

                  (e) 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 5.12. Notices to Clearing Agency. To the extent that a
notice or other communication to the Owners is required under this Trust
Agreement, unless and until Definitive Preferred Securities Certificates shall
have been issued to Owners pursuant to Section 5.13, the 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 provide notices directly to
the Owners.

                  SECTION 5.13. Definitive Preferred Securities Certificates.
Notwithstanding any other provision in this Trust Agreement other than as
provided for in Section 5.4(b)(vi), no Global Certificate may be exchanged in
whole or in part for Preferred Securities registered, and no transfer of a
Global Certificate in whole or in part may be registered, in the name of any
Person other than the Clearing Agency for such Global Certificate or a nominee
thereof unless (i) such Clearing Agency (A) has notified the Depositor that it
is unwilling or unable to continue as Clearing Agency for such Global
Certificate or (B) has ceased to be a clearing agency registered as such under
the Securities Exchange Act of 1934, as amended, and in either case the Trust
and the Depositor thereupon fails to appoint a successor Clearing Agency, (ii)
the Trust and the Depositor, at their option, notify the Property Trustee in
writing that it elects to cause the issuance of the Preferred Securities in
certificated form or (iii) there shall have occurred and be continuing an Event
of Default or any event which after notice or lapse of time or both would be an
Event of Default. In all cases, Certificated Preferred Securities delivered in
exchange for any Global Certificate or beneficial interests therein will be
registered in the names, and issued in any approved denominations, requested by
or on behalf of the Clearing Agency (in accordance with its customary
procedures).

                                      52

                  SECTION 5.14. Rights of Securityholders. 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 Securityholders shall
not have any right or title therein other than the undivided beneficial interest
in the assets of the Trust conferred by their Trust Securities and they shall
have no right to call for any partition or division of property, profits or
rights of the Trust except as described below. The Trust Securities shall be
personal property giving only the rights specifically set forth therein and in
this Trust Agreement. The Trust Securities shall have no preemptive or similar
rights and, when issued and delivered to Securityholders against payment of the
purchase price therefor, will be fully paid and nonassessable by the Trust. The
Holders of the Trust Securities, in their capacities as such, shall be entitled
to the same limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware.

                  Section 5.15. Restrictive Legends. (a) The Restricted Global
Certificate and the Certificated Preferred Securities shall bear the following
legend (the "Restricted Securities Legend") unless the Depositor determines
otherwise in accordance with applicable law:

                  "THE SECURITIES EVIDENCED HEREBY AND THE COMMON STOCK ISSUABLE
UPON THEIR CONVERSION HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF
1933 (THE "SECURITIES ACT") AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE
TRANSFERRED EXCEPT (A) BY ANY INITIAL INVESTOR THAT IS NOT A QUALIFIED
INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT,
(1) TO A PERSON WHO THE TRANSFEROR REASONABLY BELIEVES IS A QUALIFIED
INSTITUTIONAL BUYER ACQUIRING FOR ITS OWN ACCOUNT OR THE ACCOUNT OF A QUALIFIED
INSTITUTIONAL BUYER IN A TRANSACTION COMPLYING WITH RULE 144A, (2) IN AN
OFFSHORE TRANSACTION COMPLYING WITH RULE 904 OF REGULATION S UNDER THE
SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE
SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (4) PURSUANT TO
AN EFFECTIVE REGISTRATION STATEMENT OR (B) BY ANY INITIAL INVESTOR THAT IS A
QUALIFIED INSTITUTIONAL BUYER OR BY ANY SUBSEQUENT INVESTOR, AS SET FORTH IN
CLAUSE (A) ABOVE OR TO AN INSTITUTION THAT IS AN ACCREDITED INVESTOR WITHIN THE
MEANING OF RULE 501(A)(1), (2), (3) OR (7) IN A TRANSACTION EXEMPT FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND, IN EACH CASE (A) AND (B),
IN COMPLI-

ANCE WITH ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES AND
OTHER JURISDICTIONS. SECURITIES OWNED BY AN INITIAL INVESTOR THAT IS NOT A
QUALIFIED INSTITUTIONAL BUYER MAY NOT BE HELD IN BOOK-ENTRY FORM AND MAY NOT BE
TRANSFERRED WITHOUT CERTIFICATION THAT THE TRANSFER COMPLIES WITH THE FOREGOING
RESTRICTIONS, AS PROVIDED IN THE TRUST AGREEMENT REFERRED TO BELOW."

                  (b) The Regulation S Preferred Securities shall bear the
following legend (the "Regulation S Legend") unless the Depositor determines
otherwise in accordance with the applicable law:

                  "THE SECURITIES EVIDENCED HEREBY AND THE COMMON STOCK ISSUABLE
UPON CONVERSION THEREOF (COLLECTIVELY, THE "SECURITIES") HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT AND MAY NOT BE OFFERED, SOLD OR DELIVERED IN
THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON,
UNLESS SUCH SECURITIES ARE REGISTERED UNDER THE SECURITIES ACT OR AN EXEMPTION
FROM THE REGISTRATION REQUIREMENTS THEREOF IS AVAILABLE."

                                   ARTICLE 6

                   ACT OF SECURITYHOLDERS; MEETINGS; VOTING

                  SECTION 6.1. Limitations on Voting Rights. (a) Except as
provided in this Section, in Section 8.9 and 10.2 and in the Indenture and as
otherwise required by law, no Holder of Preferred Securities shall have any
right to vote or in any manner otherwise control the administration, operation
and management of the Trust or the obligations of the parties hereto, nor shall
anything herein set forth, or contained in the terms of the Trust Securities
Certificates, be construed so as to constitute the Securityholders from time to
time as partners or members of an association.

                  (b) Subject to Section 8.2 hereof, if an Event of Default with
respect to the Preferred Securities has occurred and been subsequently cured,
waived or otherwise eliminated, the provisions of Section 6.1(b)(ii) hereof
shall apply. During (x) the period commencing on the date of the occurrence of
an Event of Default with respect to the Preferred Securities and ending on the
date when such Event of Default is cured, waived or otherwise eliminated, or (y)
any period not described in either the preceding sentence or

                                      54
<PAGE>
 
the preceding clause (x), the provisions of Section 6.1(b)(i) shall apply.

                           (i) The holders of a majority in aggregate
         liquidation amount of the Preferred Securities will have the right to
         direct the time, method and place of conducting any proceeding for any
         remedy available to the Property Trustee or to exercise any trust or
         power conferred upon the Property Trustee under the Trust Agreement,
         including the right to direct the Property Trustee to exercise the
         remedies available to it as a holder of the Debentures but excluding
         the right to direct the Property Trustee to consent to an amendment,
         modification or termination of the Indenture (which shall be as
         provided below). So long as any Debentures are held by the Property
         Trustee, the Trustees shall not (A) direct the time, method and place
         of conducting any proceeding for any remedy available to the Debenture
         Trustee, or executing any trust or power conferred on the Debenture
         Trustee with respect to such Debentures, (B) waive any past default
         which is waivable under Section 5.13 of the Indenture, (C) exercise any
         right to rescind or annul a declaration that the principal of all the
         Debentures shall be due and payable or (D) consent to any amendment,
         modification or termination of the Indenture or the Debentures, where
         such consent shall be required, without, in each case, obtaining the
         prior approval of the Holders of a majority in aggregate Liquidation
         Amount of all Outstanding Preferred Securities (except in the case of
         clause (D), which consent, in the event that no Event of Default shall
         occur and be continuing, shall be of the Holders of all Trust
         Securities, voting together as a single class); 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 Trustees shall not revoke any
         action previously authorized or approved by a vote of the Holders of
         the Preferred Securities, except by a subsequent vote of the Holders of
         the Preferred Securities. The Property Trustee shall notify all Holders
         of record of the Preferred Securities of any notice of default received
         from the Debenture Trustee with respect to the Debentures. In addition
         to obtaining the foregoing approvals of the Holders of the Preferred
         Securities, prior

                                      55
<PAGE>
 
to taking any of the foregoing actions, the 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 or partnership for United States Federal income tax purposes on
account of such action.

          (ii) Subject to Section 8.2 of this Trust Agreement and only after the
Event of Default with respect to the Preferred Securities has been cured,
waived, or otherwise eliminated the holders of a majority in aggregate
liquidation amount of the Common Securities will have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Property Trustee or to exercise any trust or power conferred upon the
Property Trustee under the Trust Agreement, including the right to direct the
Property Trustee to exercise the remedies available to it as a holder of the
Debentures but excluding the right to direct the Property Trustee to consent to
an amendment, modification or termination of the Indenture (which shall be as
provided below). So long as any Debentures are held by the Property Trustee, the
Trustees shall not (A) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (B) waive any past default which is waivable under Section 5.13 of
the Indenture, (C) exercise any right to rescind or annul a declaration that the
principal of all the Debentures shall be due and payable or (D) consent to any
amendment, modification or termination of the Indenture or the Debentures, where
such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of a majority in aggregate Liquidation Amount of all
Common Securities (except in the case of clause (D), which consent, in the event
that no Event of Default shall occur and be continuing, shall be of the Holders
of all Trust Securities, voting together as a single class); 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 Common
Securities. The Trustees shall not revoke any action previ-

                                      56
<PAGE>
 
         ously authorized or approved by a vote of the Holders of the Common
         Securities, except by a subsequent vote of the Holders of the Common
         Securities. The Property Trustee shall notify all Holders of record of
         the Common Securities of any notice of default received from the
         Debenture Trustee with respect to the Debentures. In addition to
         obtaining the foregoing approvals of the Holders of the Common
         Securities, prior to taking any of the foregoing actions, the 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 or partnership
         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 Trustees otherwise propose to effect 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 a majority in
aggregate Liquidation Amount of the Outstanding Preferred Securities.

                  SECTION 6.2. Notice of Meetings. Notice of all meetings of the
Holders of the 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
Preferred Securityholder of record, at its 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.

                  SECTION 6.3. Meetings of Preferred Security- holders. No
annual meeting of Securityholders is required to be held. The Administrative
Trustees, however, shall call a meeting of Securityholders to vote on any matter
upon the written request of the Preferred Securityholders of record of 25% of
the Preferred Securities (based upon their Liquidation Amount) and the
Administrative Trustees or the Property Trustee may, at any time in their
discretion, call

                                      57
<PAGE>
 
a meeting of the Holders of Preferred Securities to vote on any matters as to
which such Holders are entitled to vote.

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

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

                  SECTION 6.4. Voting Rights. Securityholders shall be entitled
to one vote for each $50 of Liquidation Amount represented by their Trust
Securities in respect of any matter as to which such Securityholders are
entitled to vote. Notwithstanding that holders of Preferred Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Preferred Securities that are owned at such time by the Depositor, the
Trustees or any affiliate of any Trustee shall, for purposes of such vote or
consent, be treated as if such Preferred Securities were not outstanding.

                  SECTION 6.5. Proxies, Etc. At any meeting of Securityholders,
any Securityholders 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 Administrative Trustees, or with such other officer or agent of the
Trust as the Administrative Trustees 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 Securityholders of record shall be
entitled to vote. When Trust Securities are held jointly by several Persons, any
one of them may vote at any meeting in person or represented 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

                                      58
<PAGE>
 
shall not be received in respect of such Trust Securities. A proxy purporting to
be executed by or on behalf of a Securityholder shall be deemed valid unless
challenged at or prior to its exercise, and the burden of proving invalidity
shall rest on the challenger. No proxy shall be valid more than three years
after its date of execution.

                  SECTION 6.6. Securityholder Action by Written Consent. Any
action which may be taken by Securityholders at a meeting may be taken without a
meeting if Securityholders holding more than a majority of all Outstanding Trust
Securities (based upon their Liquidation Amount) entitled to vote in respect of
such action (or such larger proportion thereof as shall be required by any
express provision of this 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 Securityholders who are entitled to notice of
and to vote at any meeting or by written consent, or to participate in any
Distribution on the Trust Securities in respect of which a record date is not
otherwise provided for in this Trust Agreement, or for the purpose of any other
action, the Property Trustee may from time to time fix a date, not more than 90
days prior to the date of any meeting of Securityholders or the payment of
Distributions or other action, as the case may be, as a record date for the
determination of the identity of the Securityholders of record for such
purposes.

                  SECTION 6.8. Acts of Securityholders. 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 Securityholders
or Owners may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Securityholders or Owners in person
or by an agent duly appointed in writing; and, except as otherwise expressly
provided herein, such action shall become effective when such instrument or
instruments are delivered to an Administrative Trustee. Such instrument or
instruments (and the action embodied therein and evidence thereby) are herein
sometimes referred to as the "Act" of the Securityholders or Owners signing such
instrument or instruments. Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this
Trust Agreement and (subject to Section 8.1) conclusive in 

                                      59
<PAGE>
 
favor of the Trustees, if made in the manner provided in this Section.

                  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgements 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 Preferred Securities shall be proved by the
Securities Register.

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

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

                  If any dispute shall arise between the Securityholders and
the Administrative Trustees or among such Securityholders or Trustees with
respect to the authenticity, validity or binding nature of any request, demand,
authorization, direction, consent, waiver or other Act of such Securityholder or
Trustee under this Article 6, then

                                      60
<PAGE>
 
the determination of such matter by the Property Trustee shall be conclusive
with respect to such matter.

                  Upon the occurrence and continuation of an Event of Default,
the holders of Preferred Securities shall rely on the enforcement by the
Property Trustee of its rights as holder of the Debentures against the
Depositor. If the Property Trustee fails to enforce its rights as holder of the
Debentures after a request therefor by a holder of Preferred Securities, such
holder may proceed to enforce such rights directly against the Depositor.
Notwithstanding the foregoing, if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Depositor to pay
interest or principal on the Debentures on the date such interest or principal
is otherwise payable (or in the case of redemption, on the Redemption Date),
then a holder of Preferred Securities shall have the right to institute a
proceeding directly against the Depositor, for enforcement of payment to such
holder of the principal amount of or interest on Debentures having a principal
amount equal to the aggregate Liquidation Amount of the Preferred Securities of
such holder after the respective due date specified in the Debentures (a "Direct
Action"). In connection with any such Direct Action, the rights of the Depositor
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.

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

                  SECTION 6.9. Inspection of Records. Upon reasonable notice to
the Administrative Trustees and the Property Trustee, the records of the Trust
shall be open to inspection by Securityholders during normal business hours for
any purpose reasonably related to such Securityholder's interest as a
Securityholder.

the 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

Depositor hereby represents and warrants for the benefit of the Securityholders
that:

                  (a) the Trust Securities Certificates issued on the Closing

                                   ARTICLE 8
                                 THE TRUSTEES

                  SECTION 8.1. Certain Duties and Responsibilities. (a) The
duties and responsibilities of the Trustees shall be as provided by this Trust
Agreement and, in the case of the Property Trustee, by the Trust Indenture Act.
The Property Trustee, before the occurrence of any Event of Default and after
the curing or waiving of all Events of Default that may have occurred, shall
undertake to perform only such duties and obligations as are specifically set
forth in this Trust Agreement and the Trust Indenture Act and no implied
covenants shall be read into this Trust Agreement against the Property Trustee.
In case an Event of Default has occurred (that has not been cured or waived
pursuant to Section 8.2) of which a responsible officer of the Property Trustee
has actual knowledge, the Property Trustee shall exercise such rights and powers
vested in it by this Trust Agreement and the Trust Indenture Act, and use the
same degree of care and skill in its exercise, as a prudent individual would
exercise or use under the circumstances in the conduct of his or her own
affairs. Notwithstanding the foregoing, no provision of this Trust Agreement
shall require the Trustees to expend or risk their own funds or otherwise incur
any financial liability in the performance of any of their duties hereunder, or
in the exercise of any of their rights or powers, if they shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Trust Agreement relating to the
conduct or affecting the liability of or affording protection to the Trustees
shall be subject to the provisions of this Section. Nothing in this Trust
Agreement

                                      64
<PAGE>
 
shall be construed to release the Administrative Trustees from liability for
their own grossly negligent action, their own grossly negligent failure to act,
or their own willful misconduct. To the extent that, at law or in equity, an
Administrative Trustee has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, such Administrative
Trustee shall not be liable to the Trust or to any Securityholder for such
Administrative Trustee's 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 Administrative Trustees otherwise
existing at law or in equity, are agreed by the Depositor and the
Securityholders to replace such other duties and liabilities of the
Administrative 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 Securityholder, by its acceptance of a Trust Security, agrees that it will
look solely to the revenue and proceeds from the Trust Property to the extent
legally available for distribution to it as herein provided and that the
Trustees are not personally liable to it for any amount distributable in respect
of any Trust Security or for any other liability in respect of any Trust
Security. This Section 8.1(b) does not limit the liability of the Trustees
expressly set forth elsewhere in this Trust Agreement or, in the case of the
Property Trustee, in the Trust Indenture Act.

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

                  (i)  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

                                      65
<PAGE>
 
         by it in good faith in accordance with the direction of the Holders of
         a majority Liquidation Amount of the Trust 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, safekeeping and physical preservation of the Debentures and
         the Payment Account shall be to deal with such property as fiduciary
         assets, 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 
<PAGE>
 
         and except to the extent otherwise required by law; and

                  (v) the Property Trustee shall not be responsible for
         monitoring the compliance by the Administrative Trustees 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 Administrative Trustees or the Depositor.

                  SECTION 8.2. Notice of Defaults. (a) Within ten 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 of Preferred
Securities, the Administrative Trustees and the Depositor, unless such Event of
Default shall have been cured or waived, provided that, except for a default in
                                         --------
the payment of principal of (or premium, if any) or interest on any of the
Debentures, the Property Trustee shall be protected in withholding such notice
if and so long as the Board of Directors, the executive committee, or a trust
committee of directors and/or responsible officers of the Property Trustee in
good faith determines that the withhold-

                                      66
<PAGE>
 
ing of such notice is in the interests of the Holders of the Preferred
Securities.

                  (b)  Within ten days after the receipt of notice of the
Depositor's exercise of its right to extend the interest payment period for 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 Securityholders, unless such exercise shall have been revoked.

                  (c)  The Holders of a majority in liquidation amount of
Preferred Securities may, by vote, on behalf of the Holders of all of the
Preferred Securities, waive any past Event of Default in respect of the
Preferred Securities and its consequences, provided that, if the underlying
                                           --------
Debenture Event of Default:

                       (i)   is not waivable under the Indenture, the Event
         of Default under the Trust Agreement shall also not be waivable; or

                       (ii)  requires the consent or vote of greater than a
         majority in principal amount of the holders of the Debentures (a "Super
         Majority") to be waived under the Indenture, the Event of Default under
         the Trust Agreement may only be waived by the vote of the Holders of
         the same proportion in liquidation amount of the Preferred Securities
         that the relevant Super Majority represents of the aggregate principal
         amount of the Debentures outstanding.

                  The provisions of Section 6.1(b) and this Section 8.2(c) shall
be in lieu of (S) 316(a)(1)(B) of the Trust Indenture Act and such 
(S) 316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from
this Trust Agreement and the Preferred Securities, as permitted by the Trust
Indenture Act. Upon such waiver, any such default shall cease to exist, and any
Event of Default with respect to the Preferred Securities 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 an Event
of Default with respect to the Preferred Securities or impair any right
consequent thereon. Any waiver by the Holders of the Preferred Securities of an
Event of Default with respect to the Preferred Securities shall also be deemed
to constitute a waiver by the Holders

                                      67
<PAGE>
 
of the Common Securities of any such Event of Default with respect to the Common
Securities for all purposes of this Trust Agreement without any further act,
vote, or consent of the Holders of the Common Securities.

                  (d)  The Holders of a majority in liquidation amount of the
Common Securities may, by vote, on behalf of the Holders of all of the Common
Securities, waive any past Event of Default with respect to the Common
Securities and its consequences, provided that, if the underlying Debenture
                                 --------
Event of Default:

                       (i)  is not waivable under the Indenture, except where
         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the Declaration as provided below in this
         Section 8.2(d), the Event of Default under the Trust Agreement shall
         also not be waivable; or

                       (ii) requires the consent or vote of a Super Majority
         to be waived, except where the Holders of the Common Securities are
         deemed to have waived such Event of Default under the Trust Agreement
         as provided below in this Section 8.2(d), the Event of Default under
         the Trust Agreement may only be waived by the vote of the Holders of
         the same proportion in liquidation amount of the Common Securities that
         the relevant Super Majority represents of the aggregate principal
         amount of the Debentures outstanding;

provided further, that each Holder of Common Securities will be deemed to have
- -------- -------
waived any such Event of Default and all Events of Default with respect to the
Common Securities and its consequences until all Events of Default with respect
to the Preferred Securities have been cured, waived or otherwise eliminated, and
until such Events of Default have been so cured, waived or otherwise eliminated,
the Property Trustee will be deemed to be acting solely on behalf of the Holders
of the Preferred Securities and only the Holders of the Preferred Securities
will have the right to direct the Property Trustee in accordance with the terms
of the Securities. The provisions of Section 6.1(b) and this Section 8.2(d)
shall be in lieu of (S)316(a)(1)(B) of the Trust Indenture Act and such
(S)316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from
this Trust Agreement and the Preferred Securities, as permitted by the Trust
Indenture Act. Subject to the foregoing provisions of this

                                      68
<PAGE>
 
Section 8.2(d), upon such waiver, any such default shall cease to exist and any
Event of Default with respect to the Common Securities 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
with respect to the Common Securities or impair any right consequent thereon.

                  (e) A waiver of an Event of Default under the Indenture by the
Property Trustee at the direction of the Holders of the Preferred Securities,
constitutes a waiver of the corresponding Event of Default under this Trust
Agreement. The foregoing provisions of this Section 8.2(e) shall be in lieu of
(S) 316(a)(1)(B) of the Trust Indenture Act and such (S) 316(a)(1)(B) of the
Trust Indenture Act is hereby expressly excluded from this Trust Agreement and
the Preferred Securities, as permitted by the Trust Indenture Act.

                  SECTION 8.3.  Certain Rights of Property Trustee. Subject to

                  (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 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 no Event of Default has occurred and is continuing and,
(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 in 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

                                      69
<PAGE>
 
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 Securityholders, 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 or the
Administrative Trustees contemplated by this Trust Agreement shall be
sufficiently evidenced by an Officers' Certificate;

                  (d)  whenever in the administration of this Trust Agreement,
the Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence of
bad faith on its part, request and rely upon an Officers' Certificate and an
Opinion of Counsel which, upon receipt of such request, shall be promptly
delivered by the Depositor or the Administrative Trustees;

                  (e)  the Property Trustee shall have no duty to accomplish any
recording, filing or registration of any instrument (including any financing or
continuation statement or any filing under tax or securities laws) or any
rerecording, refiling or 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 or any Opinion of
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; and 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

Agreement, unless such Securityholders 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;

                  (h) the Property Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolutions, certificate,
statement, instrument, opinion, report, notice, request, consent, order,
approval, bond, debenture, note or other evidence of indebtedness or other paper
or document, unless requested in writing to do so by Holders of record of 25% or
more of the Preferred Securities (based upon their Liquidation Amount), but the
Property Trustee may make such further inquiry or investigation into such facts
or 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 or an Affiliate, 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 permissive power or authority available to the Property Trustee
shall be construed to be a duty.

                  SECTION 8.4. Not Responsible for Recitals or Issuance of
Securities. The recitals contained herein and in the Trust Securities
Certificates shall not be taken as the statements of the Trustees, and the
Trustees do not assume any responsibility for their correctness. The Trustees
shall not be accountable for the use or application by the Depositor of the
proceeds of the Debentures.

                  SECTION 8.5. May Hold Securities. Except as provided in the
definition of the term "Outstanding" in Article 1, any Trustee or any other
agent of any Trustee or the Trust, in its individual or any other capacity, may

                  (a) to pay the Trustees from time to time reasonable

trustee of an express trust);

                  (b) except as otherwise expressly provided herein, to
reimburse the Trustees upon request for all reasonable expenses, disbursements

                  (c) to the fullest extent permitted by applicable law, to
indemnify and hold harmless (i) each Trustee, (ii) any Affiliate of any Trustee,
(iii) any officer, director, shareholder, employee, representative or agent of
any Trustee, and (iv) any employee or agent of the Trust or its Affiliates
(referred to herein as an "Indemnified Person") from and against any loss,
damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of any

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

entity.

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

                  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

                       (ii)  after the issuance of any Securities, by vote of
         the Holders of a majority in liquidation amount of the Common
         Securities voting as a class.

                  (b)  The Trustee that acts as Property Trustee shall not be
removed in accordance with Section 8.9(a) until a successor possessing the

Delaware Trustee")

                                      74
<PAGE>
 
has been appointed and has accepted such appointment by instrument executed by
such Successor Delaware Trustee and delivered to the Trust, the Depositor and
the removed Delaware Trustee.

          (d)  A Trustee appointed to office shall hold office until
his, her or its successor shall have been appointed or until his, her or its
death, removal, resignation, dissolution or liquidation. Any Trustee may resign
from office (without need for prior or subsequent accounting) by an instrument
in writing signed by the Trustee and delivered to the Depositor and the Trust,
which resignation shall take effect upon such delivery or upon such later date
as is specified therein; provided, however, that:
                         --------  -------

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

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

               liquidated and the proceeds thereof distributed to the holders of
               the Securities; and

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

          (e)  The Holders of the Common Securities shall use their best efforts
to promptly appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be, if the Property Trustee or the Delaware Trustee delivers an
instrument of resignation in accordance with Section 8.9(d).

          (f)  If no Successor Property Trustee or Successor Delaware Trustee
shall have been appointed and accepted

                                      75
<PAGE>
 
appointment as provided in this Section 8.9 within 60 days after delivery
pursuant to this Section 8.9 of an instrument of resignation or removal, the
Property Trustee or Delaware Trustee resigning or being removed, as applicable,
may petition any court of competent jurisdiction for appointment of a Successor
Property Trustee or Successor Delaware Trustee. Such court may thereupon, after
prescribing such notice, if any, as it may deem proper and prescribe, appoint a
Successor Property Trustee or Successor Delaware Trustee, as the case may be.

          (g)  No Property Trustee or Delaware Trustee shall be liable for the
acts or omissions to act of any Successor Property Trustee or Successor Delaware

          (h)  The Property Trustee shall give notice of each resignation and
each removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 10.8 and shall give notice to
the Depositor. 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.

          (i)  Notwithstanding the foregoing or any other provision of this
Trust Agreement, in the event any Administrative Trustee or 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 (a) the unanimous act of the remaining
Administrative Trustees if there are at least two of them or (b) otherwise by
the Depositor (with the successor in each case being a Person who satisfies the
eligibility requirement for Administrative Trustees or the Delaware Trustee, as
the case may be, set forth in Section 8.7).

          (j)  The indemnity provided to a Trustee under Section 8.6 shall
survive any Trustee's resignation or removal.

          SECTION 8.10.  Acceptance of Appointment by Successor.  In case of the
appointment hereunder of a successor Trustee, such successor Trustee so
appointed shall execute, acknowledge and deliver to the Trust and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee;

                                      76
<PAGE>
 
but, on the request of the Depositor or the successor Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Depositor or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and if the Property Trustee is the
resigning Trustee shall duly assign, transfer and deliver to the successor
Trustee all property and money held by such retiring Property Trustee hereunder.

          In case of the appointment hereunder of a successor Relevant Trustee,
the retiring Relevant Trustee and each successor Relevant Trustee 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 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 trusts hereunder 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.

          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.

                                      77

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 8.12.  Preferential Collection of Claims Against Depositor or 
Trust.  If and when the Property Trustee shall be or become a creditor of the
Depositor or the Trust (or any other obligor upon the Debentures or the Trust
Securities), the Property Trustee 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 8.13.  Reports by Property Trustee.  (a)  To the extent
required by the Trust Indenture Act, within 60 days after December 31 of each

all Securityholders in accordance with Section 10.8 and to the Depositor, a
brief report dated as of such December 31 with respect to:

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

          (ii)  a statement that the Property Trustee has complied with all of
     its obligations under this Trust Agreement during the twelve-month period

<PAGE>
 
     ing Date) ending with such December 31 or, if the Property Trustee has not
     complied in any material respects with such obligations, a description of
     such noncompliance; and

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

          (b)  In addition, the Property Trustee shall transmit to
Securityholders 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 provided pursuant thereto.

          (c)  A copy of such report shall, at the time of such transmissions to
Holders, be filed by the Property Trustee with each national securities exchange
or self-regulatory organization upon which the Trust Securities are listed, with
the Commission and with the Depositor.

          SECTION 8.14.  Reports to the Property Trustee.  The Depositor and the

times required by Section 314 of the Trust Indenture Act.

          SECTION 8.15.  Evidence of Compliance with Conditions Precedent.  Each
of the Depositor and the Administrative Trustees on behalf of the Trust shall
provide to the Property Trustee such evidence of compliance with any conditions
precedent, if any, provided for in this Trust Agreement that relate to any of
the matters set forth in Section 314(c) of the Trust Indenture Act. Any
certificate or opinion required to be given by an officer pursuant to Section
314(c)(1) of the Trust Indenture Act shall be given in the form of an Officers'
Certificate.

          SECTION 8.16.  Number of Trustees.  (a) The number of Trustees shall
be five, provided that the Holder of all of the Common Securities by written
instrument may increase

                                      79
<PAGE>
 
or decrease the number of Administrative Trustees. The Property Trustee and the
Delaware Trustee may be the same Person.

          (b)  If a Trustee ceases to hold office for any reason and the number
of Administrative Trustees is not reduced pursuant to Section 8.16(a), or if the
number of Trustees is increased pursuant to Section 8.16(a), a vacancy shall
occur.

          (c)  The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to annul the Trust. Whenever a vacancy in the number of Administrative Trustees
shall occur, until such vacancy is filled by the appointment of an
Administrative Trustee in accordance with Section 8.9, the Administrative
Trustees in office, regardless of their number (and notwithstanding any other
provision of this Agreement), shall have all the powers granted to the
Administrative Trustees and shall discharge all the duties imposed upon the
Administrative Trustees by this Trust Agreement.

          SECTION 8.17.  Delegation of Power.  (a)  Any Administrative Trustee
may, by power of attorney consistent with applicable law, delegate to any other
natural person over the age of 21 his or her power for the purpose of executing

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

                      TERMINATION, LIQUIDATION AND MERGER

          SECTION 9.1.  Termination upon Expiration Date.  Unless earlier
terminated, the Trust shall automatically terminate on November 25, 2041 (the
"Expiration Date"), following the distribution of the Trust Property in
accordance with Section 9.4.

          SECTION 9.2.  Early Termination.  The first to occur of any of the
following events is an "Early Termination Event":

          (a)  the occurrence of a Bankruptcy Event in respect of, or the 
dissolution or liquidation of, the Depositor;

          (b)  the occurrence of a Special Event except in the case of a Tax
Event following which the Depositor has elected (i) to pay any Additional Sums
(in accordance with Section 4.4) such that the net amount received by Holders of
Preferred Securities in respect of Distributions are not reduced as a result of
such Tax Event and the Depositor has not revoked any such election or failed to
make such payments or (ii) to redeem all or some of the Debentures pursuant to
Section 4.4(a);

          (c)  the redemption, conversion or exchange of all of the Trust
Securities;

          (d)  an order for dissolution of the Trust shall have been entered by
a court of competent jurisdiction and

          (e)  receipt by the Property Trustee of written notice from the
Depositor at any time (which direction is optional and wholly within the
discretion of the Depositor) of its intention to terminate the Trust and
distribute the Debentures in exchange for the Preferred Securities.

          SECTION 9.3.  Termination.  The respective obligations and
responsibilities of the Trustees and the Trust created and continued hereby
shall terminate upon the latest to occur of the following: (a) the distribution
by the Property Trustee to Securityholders upon the liquidation of the Trust
pursuant to Section 9.4, or upon the redemption of all of the Trust Securities
pursuant to Section 4.2, of all amounts required to be distributed hereunder
upon the final

                                      81
<PAGE>
 
payment of the Trust Securities; (b) the payment of all expenses owed by the
Trust; and (c) the discharge of all administrative duties of the Administrative
Trustees, including the performance of any tax reporting obligations with
respect to the Trust or the Securityholders.

          SECTION 9.4.  Liquidation.  (a)  If an Early Termination Event
specified in clause (a), (b), (d) or (e) of Section 9.2 occurs or upon the
Expiration Date, the Trust shall be liquidated by the Trustees as expeditiously
as the Trustees determine to be possible by distributing, after satisfaction of
liabilities to creditors of the Trust as provided by applicable law, to each
Securityholder an aggregate principal amount of Debentures equal to the
aggregate Liquidation Amount of Trust Securities held by such Holder, 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 as it appears 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 an aggregate principal amount of Debentures equal to the
     aggregate Liquidation Amount of Preferred Securities held by such Holder;
     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
     Administrative Trustees or the Property Trustee 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
Securityholders, 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

                                      82
<PAGE>
 
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

          (c)  Except where Section 9.2(c) or 9.4(d) applies, after the
Liquidation Date, (i) the Trust Securities will no longer be deemed to be
Outstanding, (ii) the Clearing Agency or its nominee, as the record holder of
such Trust Securities, will receive a registered global certificate or
certificates representing the Debentures to be delivered upon such distribution
and (iii) any Trust Securities Certificates not held by the Clearing Agency will
be deemed to represent an aggregate principal amount of Debentures equal to the
aggregate Liquidation Amount of Preferred Securities held by such Holders, and
bearing accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on such Trust Securities until such certificates are presented to
the Property Trustee for transfer or reissuance.

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

                                      83
<PAGE>
 
occurred and is continuing, the Preferred Securities shall have a priority over
the Common Securities.

          SECTION 9.5.  Mergers, Consolidations, Amalgamations or Replacements 
of the Trust.  The Trust may not merge with or into, consolidate, amalgamate, or
be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 9.5. At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the Property Trustee, the
Delaware Trustee or the Holders of the Preferred Securities, the Trust may merge
with or into, consolidate, 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 (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities") so long as the Successor Securities rank
the same as the Preferred Securities rank in priority with respect to
Distributions and payments upon liquidation, redemption and otherwise, (ii) 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,
(iii) the Successor Securities are listed, 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, if any,
(iv) such merger, consolidation, amalgamation, replacement, conveyance, transfer
or lease does not cause the Preferred Securities (including any Successor
Securities) to be downgraded by any nationally recognized statistical rating
organization, (v) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the Holders of the Preferred Securities (including any
Successor Securities) in any material respect, (vi) such successor entity has a
purpose identical to that of the Trust, (vii) prior to such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease the
Depositor has received an Opinion of Counsel to the effect that (a) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the Holders of the
Preferred Securi-

                                      84
<PAGE>
 
ties (including any Successor Securities) in any material respect (other than
with respect to any dilution of the Holder's interest in the new entity), (b)
following such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease neither the Trust nor such successor entity will be required
to register as an investment company under the 1940 Act, and (c) following such
merger, consolidation, amalgamation or replacement, the Trust or such successor
entity will be treated as a grantor trust for United States Federal income tax
purposes and (viii) the Depositor or any permitted successor or assignee owns
all of the Common Securities of such successor entity and guarantees the
obligations of such successor entity under the Successor Securities at least to
the extent provided by the Guarantee. Notwithstanding the foregoing, the Trust
shall not, except with the consent of Holders of 100% in aggregate Liquidation
Amount of the Preferred Securities, consolidate, amalgamate, merge with or into,
be replaced by or convey, transfer or lease its properties and assets
substantially as an entirety to any other entity or permit any other entity to
consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, replacement, conveyance, transfer or lease
would cause the Trust or the successor entity to be classified as other than a
grantor trust for United States Federal income tax purposes.

                                  ARTICLE 10
                           MISCELLANEOUS PROVISIONS

          SECTION 10.1.  Limitation of Rights of Securityholders.  The death or 
incapacity of any person having an interest, beneficial or otherwise, in Trust
Securities shall not operate to terminate this Trust Agreement, nor entitle the
legal representatives or heirs of such person or any Securityholder for such
person to claim an accounting, take any action or bring any proceeding in any
court for a partition or winding-up of the arrangements contemplated hereby, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

          SECTION 10.2.  Amendment.  (a)  This Trust Agreement may be amended
from time to time by the Trustees and the Depositor, without the consent of any
Securityholders, (i) to cure any ambiguity, correct or supplement any provision
herein which may be inconsistent with any other provision herein, or to make any
other provisions with respect to

                                      85
<PAGE>
 
matters or questions arising under this Trust Agreement, which shall not be
inconsistent with the other provisions of this Trust Agreement, (ii) to modify,
eliminate or add to any provisions of this Trust Agreement to such extent as
shall be necessary to ensure that the Trust will be classified for United States
Federal income tax purposes as a grantor trust at all times that any Trust
Securities are Outstanding or to ensure that the Trust will not be required to
register as an "investment company" under the 1940 Act, or be classified as
other than a grantor trust for United States Federal income tax purposes, or
(iii) to comply with the requirements of the Commission in order to effect or
maintain the qualification of this Trust Agreement under the Trust Indenture
Act; provided, however, that in the case of clause (i), such action shall not
adversely affect in any material respect the interests of any Securityholder,
and any amendments of this Trust Agreement shall become effective when notice
thereof is given to the Securityholders.

          (b)  Except as provided in Section 10.2(c) hereof, any provision of
this Trust Agreement may be amended by the Trustees and the Depositor with (i)
the consent of Holders representing not less than a majority (based upon
Liquidation Amounts) of the Trust Securities then Outstanding, acting as a
single class, and (ii) receipt by the Trustees of an Opinion of Counsel to the
effect that such amendment or the exercise of any power granted to the Trustees
in accordance with such amendment will not affect the Trustee's status as a
grantor trust for United States Federal income tax purposes or the Trust's
exemption from the status of an "investment company" under the 1940 Act,
provided, however, if any amendment or proposal that would adversely affect the
powers, preferences or special rights of the Trust Securities, whether by way of
amendment or otherwise, would adversely affect only the Preferred Securities or
only the Common Securities, then only the affected class will be entitled to
vote on such amendment or proposal and such amendment or proposal shall not be
effective except with the approval of a majority in liquidation amount of such
class of Trust Securities.

          (c)  In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or other-

                                      86
<PAGE>
 
wise adversely affect the amount of any Distribution required to be made in
respect of the Trust Securities as of a specified date or (ii) restrict the
right of a Securityholder to institute suit for the enforcement of any such
payment on or after such date; notwithstanding any other provision herein,
without the unanimous consent of the Securityholders (such consent being
obtained in accordance with Section 6.3 or 6.6 hereof), this paragraph (c) of
this Section 10.2 may not be amended.

          (d)  Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
the status of an "investment company" under the 1940 Act or be classified as
other than a grantor trust for United States Federal income tax purposes.

          (e)  Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor, this Trust Agreement may not be amended in
a manner which imposes any additional obligation on the Depositor.

          (f)  In the event that any amendment to this Trust Agreement is made,
the Administrative Trustees shall promptly provide to the Depositor a copy of
such amendment.

          (g)  Neither the Property Trustee nor the Delaware Trustee shall be
required to enter into any amendment to this Trust Agreement which affects its
own rights, duties or immunities under this Trust Agreement. The Property
Trustee shall be entitled to receive an Opinion of Counsel and an Officers'
Certificate stating that any amendment to this Trust Agreement is in compliance
with this Trust Agreement.

          SECTION 10.3.  Separability.  In case any provision in this Trust
Agreement or in the Trust Securities Certificates shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

          SECTION 10.4.  GOVERNING LAW.  THIS TRUST AGREEMENT AND THE RIGHTS AND
OBLIGATIONS OF EACH OF THE SECURITYHOLDERS, THE TRUST AND TRUSTEES WITH RESPECT
TO THIS TRUST AGREEMENT IN THE TRUST SECURITIES SHALL BE CONSTRUED IN ACCORDANCE
WITH AND GOVERNED BY THE LAWS OF THE STATE OF DELA-

<PAGE>
 
WARE WITHOUT REGARD TO ITS CONFLICT OF LAWS PRINCIPLES AND EXCLUDING SECTIONS
3540 AND 3561 OF TITLE 12 THEREOF.

          SECTION 10.5.  Payments Due on Non-Business Day.  If the date fixed
for any payment on any Trust Security shall be a day which is not a Business
Day, then such payment need not be made on such date but may be made on the next
succeeding day which is a Business Day except as otherwise provided in Section
4.1(a) and Section 4.2(d)), with the same force and effect as though made on the
date fixed for such payment, and no interest shall accrue thereon for the period
after such date.

          SECTION 10.6.  Successors.  This Trust Agreement shall be binding upon
and shall inure to the benefit of any successor to the Depositor, the Trust or
the Relevant Trustee, including any successor by operation of law. Except in
connection with a consolidation, merger or sale involving the Depositor that is
permitted under Article 8 of the Indenture and pursuant to which the assignee
agrees in writing to perform the Depositor's obligations hereunder, the
Depositor shall not assign its obligations hereunder.

          SECTION 10.7.  Headings.  The Article and Section headings are for
convenience only and shall not affect the construction of this Trust Agreement.

          SECTION 10.8.  Reports, Notices and Demands.  Any report, notice,
demand or other communications which by any provision of this Trust Agreement is
required or permitted to be given or served to or upon any Securityholder or the
Depositor may be given or served in writing by deposit thereof, first-class
postage prepaid, in the United States mail, hand delivery or facsimile
transmission, in each case, addressed, (a) in the case of a Holder of Preferred
Securities, to such Holder as such Holder's name and address may appear on the
Securities Register; and (b) in the case of the Holder of the Common Securities.

          Any notice to Preferred Securityholders shall also be given to such
Owners as have, within two years preceding the giving of such notice, filed
their names and addresses with the Property Trustee for that purpose. Such
notice, demand or other communication to or upon a Securityholder shall be
deemed to have been sufficiently given, or made, for all purposes, upon hand
delivery, mailing or transmission.

                                      88
<PAGE>
 
          Any notice, demand or other communication which by any provision of
this Trust Agreement is required or permitted to be given or served to or upon
the Trust, the Property Trustee, the Delaware Trustee or the Administrative
Trustees shall be given in writing addressed (until another address is published
by the Trust) as follows: (a) with respect to the Property Trustee, to IBJ
Schroder Bank & Trust Company, One State Street, 11th Floor, New York, New York
10004, Attention: Corporate Trust & Agency Department, (b) with respect to the
Delaware Trustee, to Delaware Trust Capital Management, Inc., 900 Market Street,
Wilmington, Delaware 19801, with a copy of any such notice to the Property
Trustee at its address above, and (c) with respect to the Administrative
Trustees, to them at the address for notices to the Depositor, marked
"Attention: Secretary". Such notice, demand or other communication to or upon
the Trust or the Property Trustee shall be deemed to have been sufficiently
given or made only upon actual receipt of the writing by the Trust or the
Property Trustee.

          SECTION 10.9.  Agreement Not to Petition.  Each of the Trustees and
the Depositor agrees for the benefit of the Securityholders that, until at least
one year and one day after the Trust has been terminated in accordance with
Article 9, it shall not file, or join in the filing of, a petition against the
Trust under any bankruptcy, insolvency, reorganization or other similar law
(including, without limitation, the United States Bankruptcy Code)
(collectively, "Bankruptcy Laws") or otherwise join in the commencement of any
proceeding against the Trust under any Bankruptcy Law. In the event the
Depositor takes action in violation of this Section 10.9, the Property Trustee
agrees, for the benefit of Securityholders, that, at the expense of the
Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Trust
or the commencement of such action and raise the defense that the Depositor has
agreed in writing not to take such action and should be stopped and precluded
therefrom and such other defenses, if any, as counsel for the Trustee or the
Trust may assert. The provisions of this Section 10.9 shall survive the
termination of this Trust Agreement.

          SECTION 10.10.  Trust Indenture Act; Conflict with Trust Indenture 
Act.  (a)  This Trust Agreement is subject to the provisions of the Trust
Indenture Act that are re-

                                      89
<PAGE>
 
quired to be part of this Trust Agreement and shall, to the extent applicable,
be governed by such provisions.

          (b)  The Property Trustee shall be the only Trustee which is the
trustee for the purposes of the Trust Indenture Act.

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

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

          SECTION 10.11.  ACCEPTANCE OF TERMS OF TRUST AGREEMENT, GUARANTEE AND
INDENTURE.  THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST
THEREIN BY OR ON BEHALF OF A SECURITYHOLDER OR BENEFICIAL OWNER, WITHOUT ANY
SIGNATURE OR FURTHER MANIFESTATION OF ASSENT, SHALL CONSTITUTE THE UNCONDITIONAL
ACCEPTANCE BY THE SECURITYHOLDER AND ALL OTHERS HAVING A BENEFICIAL INTEREST IN
SUCH TRUST SECURITY OF ALL THE TERMS AND PROVISIONS OF THIS TRUST AGREEMENT AND
AGREEMENT TO SUBORDINATION PROVISIONS AND OTHER TERMS OF THE GUARANTEE AND THE
INDENTURE, AND SHALL CONSTITUTE THE AGREEMENT OF THE TRUST, SUCH SECURITYHOLDER
AND SUCH OTHERS THAT THE TERMS AND PROVISIONS OF THIS TRUST AGREEMENT SHALL BE
BINDING, OPERATIVE AND EFFECTIVE AS THE TRUST AND SUCH SECURITYHOLDER AND SUCH
OTHERS.

          SECTION 10.12.  Counterparts.  This Trust Agreement may contain more
than one counterpart of the signature page and this Trust Agreement may be
executed by the affixing of the signature of each of the Trustees to one of such
counterpart signature pages. All of such counterpart signature pages shall be
read as though one, and they shall have the same force and effect as though all
of the signers had signed a single signature page.

         CERTIFICATE No(s). __________________

         The Person in whose name this certificate is executed below
(the "Undersigned") hereby certifies that either (i) it is the sole beneficial
owner of the Specified Securities or (ii) it is acting on behalf of all the
beneficial owners of the Specified Securities and is duly authorized by them to

                  The Owner has requested that the Specified Securities be

accordance with Rule 904 or Rule 144 under the Securities Act and with all
applicable securities laws of the states of the United States and other
jurisdictions. Accordingly, the Owner hereby further certifies as follows:

                  (1)      Rule 904 Transfers.  If the transfer is being
effected in accordance with Rule 904:

                  (A)      the Owner is not a distributor of the Securities, an
affiliate of the Company or any such distributor or a person acting on behalf of

                  (C)      either:

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

                           (ii) the transaction is being executed in, on or
         through the facilities of the Eurobond market, as regulated by the
         Association of International Bond Dealers, or another designated
         offshore securities market and neither the Owner nor any person acting
         on its behalf knows that the transaction has been prearranged with a
         buyer in the United States;

                  (D)      no directed selling efforts have been made in the
United States by or on behalf of the Owner or any affiliate thereof;

<PAGE>
 
                  (E)   if the Owner is a dealer in securities or has received a
selling concession, fee or other remuneration in respect of the Specified
Securities, and the transfer is to occur during the Restricted Period, then the
requirements of Rule 904(c)(1) have been satisfied; and

                  (F)   the transaction is not part of a plan or
scheme to evade the registration requirements of the Securi-
ties Act.

                  (2)   Rule 144 Transfers.  If the transfer is being
effected pursuant to Rule 144:

                  (A)   the transfer is occurring after a holding period of at
least two years (computed in accordance with paragraph (d) of Rule 144) has
lapsed since the Specified Securities were last acquired from the Trust or from
an affiliate of the Trust, whichever is later, and is being effected in
accordance with the applicable amount, manner of sale and notice requirements of
Rule 144; or

                  (B)   the transfer is occurring after a holding period of at
least three years has elapsed since the Specified Securities were last acquired
from the Trust or from an affiliate of the Trust, whichever is later, and the
Owner is not, and during the preceding three months has not been, an affiliate
of the Trust.

future Holder of the same Debenture and the Holder of every Debenture issued

record date.

hereunder to give or take any such action with regard to any particular
Debenture may do so with regard to all or any part of the principal amount of
such Debenture or by one or more duly appointed agents each of

                                      18

furnished to, or filed with

                  (a) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         or

                  (b) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose (except as otherwise provided in Section
         5.1 hereof) hereunder if in writing and mailed, first class, postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the first paragraph of this instrument or at any
         other address previously furnished in writing to the Trustee by the

such Holder as it appears in the Securities Register on the date such notice is
mailed, which shall be not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition prece-
dent to the validity of any action taken in reliance upon such waiver.

                                      19
<PAGE>
 
         In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

this Indenture limits, qualifies or conflicts with a provision of the Trust
Indenture Act that is required under such act to be a part of and govern this
Indenture, the latter provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the former provision shall be deemed to apply.

         SECTION 1.8.  Effect of Headings and Table of Contents. The Article and
Section headings herein and the Table of Contents are for convenience only and
shall not affect the construction hereof.

         SECTION 1.9.  Successors and Assigns.  All covenants and agreements in
this Indenture by the Company shall bind its successors and assigns, whether so
expressed or not.

         SECTION 1.10. Separability Clause.  In case any provision in this
Indenture or in the Debentures shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

         SECTION 1.11. Benefits of Indenture. Nothing in this Indenture or in
the Debentures, express or implied, shall give to any Person, other than the
parties thereto, any Paying Agent and their successors and assigns and the
Holders of the Debentures, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

be governed by and construed in accordance with the laws of the State of New

Payment Date, Redemption Date, or Stated

                                      20

other provision of this Indenture or the Debentures) payment of interest or

         Host Marriott Corporation, a corporation organized and existing under
the laws of Delaware (hereinafter called the "Company", which term includes any
successor corporation under the Indenture hereinafter referred to), for value
received, hereby promises to pay to__________________________________, or
registered assigns, the principal sum of _______________________________________
on December 2, 2026 and to pay interest on said principal sum from December 2,
1996 or from the most recent interest payment date (each such date, an "Interest
Payment Date") on which interest has been paid or duly provided for, quarterly
plus Additional Interest, if any until the principal hereof is paid or duly
provided for or made available for payment subject to deferral as set forth
herein in arrears on March 1, June 1, September 1 and December 1 of each year,
commencing March 1, 1997 at the rate of 6 3/4% per annum, until the principal
hereof shall have become due and payable.

         Reference is hereby made to the further provisions of this Debenture
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this
Debenture shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

         IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed.

Dated:

                                               By:
                                                  ------------------------------


         SECTION 2.3. Form of Reverse of Debenture.  This Debenture is one of a
duly authorized issue of Debentures of the Company (herein called the
"Debentures") limited to the aggregate principal amount of $567,050,000, issued
and to be issued under an Indenture, dated as of December 2, 1996 (herein called
the "Indenture"), between the Company and IBJ Schroder Bank & Trust Company, as
Trustee (herein called the "Trustee", which term includes any

                                      22
<PAGE>
 
successor trustee under the Indenture), to which the Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of
the Trustee, the Company and the Holders of the Debentures, and of the terms
upon which the Debentures are, and are to be, authenticated and delivered. All
terms used in this Debenture that are defined in the Indenture shall have the
meanings assigned to them in the Indenture.

         The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30 day months. For periods less than a full
month, interest shall be computed on the actual number of elapsed days over 360
days. In the event that any date on which interest is payable on this Debenture
is not a Business Day, then a payment of the interest on such date will be made
on the next succeeding day which is a Business Day (and without any interest or
other payment in respect of any such delay) with the same force and effect as if
made on the date the payment was originally payable. A "Business Day" shall mean
any day other than a Saturday or a Sunday or a day on which banking institutions
in the City of New York are authorized or required by law or executive order to
remain closed or a day on which the Corporate Trust Office of the Trustee, or
the principal office of the Property Trustee under the Trust Agreement is closed
for business. The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Debenture (or one or more Predecessor
Debentures, as defined in the Indenture) is registered at the close of business
on the Regular Record Date, for such interest installment which shall be the
date which is the Business Day next preceding such Interest Payment Date. Any
such interest installment not so punctually paid or duly provided for shall
forthwith cease to be payable to the Holder on such Regular Record Date and may
either be paid to the Person in whose name this Debenture (or one or more
Predecessor Debentures) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Debentures not less than 10
days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the

                                      23
<PAGE>
 
requirements of any securities exchange on which the Debentures may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in the Indenture.

         The Company shall have the right at any time during the term of this
Debenture, from time to time, to extend the interest payment period of such
Debenture for up to 20 consecutive quarters with respect to each deferral period
(each such deferral period an "Extension Period"), during which periods the
Company shall have the right not to make payments of interest on any Interest
Payment Date, and at the end of which the Company shall pay all interest then
accrued and unpaid (together with Additional Interest and Liquidated Damages, if
any, thereon to the extent permitted by applicable law); provided that during
any such Extension Period, the Company will not, and will not permit any
Subsidiary to (a) declare or pay any dividends or distributions on, or redeem,
purchase, acquire or make a liquidation payment with respect to, any shares of
the Company's capital stock or (b) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities
(including guarantees of indebtedness for money borrowed) of the Company that
rank pari passu with or junior to the Debentures (other than (i) any dividend,
redemption, liquidation, interest, principal or guarantee payment by the Company
where the payment is made by way of securities (including capital stock) that
rank pari passu with or junior to the securities on which such dividend,
redemption, interest, principal or guarantee payment is being made, (ii)
redemptions or purchases of any rights pursuant to the Company's Shareholders
Rights Plan, or any successor to such Shareholders Rights Plan, and the
declaration of a dividend of such rights or the issuance of preferred stock
under such plans in the future, (iii) payments under the Guarantee, (iv)
purchases of Common Stock related to the issuance of Common Stock under any of
the Company's benefit plans for its directors, officers or employees, (v) as a
result of a reclassification of the Company's capital stock or the exchange or
conversion of one series or class of the Company's capital stock for another
series or class of the Company's capital stock and (vi) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
conversion or exchange provisions of such capital stock or the security being
converted or exchanged). Prior to

                                      24
<PAGE>
 
the termination of any such Extension Period, the Company may further extend the
interest payment period, provided that no Extension Period shall exceed 20
consecutive quarters or extend beyond the Stated Maturity of this Debenture.
Upon the termination of any such Extension Period and upon the payment of all
accrued and unpaid interest and any Additional Interest then due, the Company
may elect to begin a new Extension Period, subject to the above requirements. No
interest shall be due and payable during an Extension Period except at the end
thereof. The Company shall give the Trustee, the Property Trustee and the
Administrative Trustees notice of its selection of an Extension Period at least
one Business Day prior to the earlier of (i) the record date for the date the
distributions on the Preferred Securities (or if no Preferred Securities are
outstanding, for the date interest on the Debentures) would have been payable
except for the election to begin such Extension Period or (ii) the date the
Property Trustee of the Host Marriott Financial Trust is (or if no Preferred
Securities are outstanding, the Debenture Trustee is) required to give notice to
NYSE or other applicable self-regulatory organizations or to holders of such
Preferred Securities (or, if no Preferred Securities are outstanding, to the
holders of such Debentures) of the record date.

         Payment of the principal of (and premium, if any) and interest on this
Debenture will be made [Insert, if a global security is issued - to the
Depositary Trust Company or its nominee] [Insert if securities in definitive
form are issued - at the office or agency of the Paying Agent maintained for
that purpose in the United States], in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts provided, however, that at the option of the Company
payment of interest may be made (i) by check mailed to the address of the Person
entitled thereto as such address shall appear in the Securities Register or (ii)
by wire transfer in immediately available funds at such place and to such
account as may be designated by the Person entitled thereto as specified in the
Securities Register.

         The indebtedness evidenced by this Debenture is, to the extent provided
in the Indenture, subordinate and subject in right of payments to the prior
payment in full of all Senior Debt (as defined in the Indenture), and

                                      25
<PAGE>
 
this Debenture is issued subject to the provisions of the Indenture with respect
thereto. Each Holder of this Debenture, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his
behalf to take such actions as may be necessary or appropriate to effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes. Each Holder hereof, by his acceptance hereof, waives
all notice of the acceptance of the subordination provisions contained herein
and in the Indenture by each holder of Senior Debt, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

         At any time on or after December 2, 1999, the Company may, at its
option, subject to the terms and conditions of Article 11 of the Indenture,
redeem this Debenture in whole at any time or in part from time to time, at the
Redemption Prices set forth in Section 11.8 of the Indenture.

         In the event of redemption of this Debenture in part only, a new
Debenture or Debentures for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

         If a Special Event shall occur and be continuing, this Debenture shall
be exchangeable for Preferred Securities in accordance with Section 11.9 of the
Indenture or, in certain circumstances, redeemable by the Company in accordance
with Section 11.8 of the Indenture.

         Subject to the terms and conditions set forth in Article 13 of the
Indenture, this Debenture is convertible, at the option of the Holder, hereof
into shares of Common Stock.

         If an Event of Default shall occur and be continuing, the principal of
the Debentures may be declared due and payable in the manner, with the effect
and subject to the conditions provided in the Indenture.

         The Indenture contains provisions for satisfaction, discharge and
defeasance of the entire indebtedness of this Debenture upon compliance by the
Company with certain conditions set forth in the Indenture.

                                      26
<PAGE>
 
         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures to be affected under the
Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in principal amount of the Debentures. The Indenture also
contains provisions permitting Holders of specified percentages in principal
amount of the Debentures at the time Outstanding, on behalf of the Holders of
all Debentures, to waive compliance by the Company with certain provisions of
the Indenture and certain past defaults under the Indenture and their
consequences. Any such consent or waiver shall be conclusive and binding upon
the Holder of this Debenture and upon all future Holders of this Debenture and
of any Debenture issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Debenture.

         As provided in and subject to the provisions of the Indenture, if an
Event of Default occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures may declare the principal amount of all the Debentures to
be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders), provided that, if upon an Event of Default,
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures fail to declare the principal of all 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 Company and the Trustee; and upon any such
declaration such principal amount (or specified amount) of and the accrued
interest (including any Additional Interest) on all the Debentures shall become
immediately due and payable, provided that the payment of principal and interest
(including any Additional Interest) on such Debentures shall remain subordinated
to the extent provided in Article 12 of the Indenture.

         No reference herein to the Indenture and no provision of this Debenture
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium,

                                      27
<PAGE>
 
if any) and interest on this Debenture at the times, place and rate, and in the
coin or currency, herein prescribed.

         The holders of the Preferred Securities, the Debentures, the Guarantee
and the shares of Common Stock of the Company issuable upon conversion of the
Securities (collectively, the "Registrable Securities") are entitled to the
benefits of a Registration Rights Agreement, dated as of December 2, 1996, among
Host Marriott Financial Trust, the Company and the Purchasers (the "Registration
Rights Agreement"). Pursuant to the Registration Rights Agreement, the Company
has agreed for the benefit of the holders of Registrable Securities that (i) it
will, at its cost, within 120 days after the date of issuance of the Registrable
Securities, file a shelf registration statement (the "Shelf Registration
Statement") with the Commission with respect to the resales of the Registrable
Securities, (ii) it will use its best efforts to cause such Shelf Registration
Statement to be declared effective by the Commission within 180 days after the
date of issuance of the Registrable Securities and (iii) the Depositor (as
defined in the Trust Agreement) will use its best efforts to maintain such Shelf
Registration Statement continuously effective under the Securities Act until the
third anniversary of the date of issuance of the Registrable Securities or such
earlier date as is provided in the Registration Rights Agreement (the
"Effectiveness Period".) The Company will be permitted to suspend the use of the
prospectus (which is a part of the Shelf Registration Statement) in connection
with sales of Registrable Securities by holders during certain periods of time
under certain circumstances relating to pending corporate developments relating
to the Company and public filings with the Commission and similar events.

         If (i) on or prior to 120 days following the date of original issuance
of the Registrable Securities, a Shelf Registration Statement has not been filed
with the Commission, or (ii) on or prior to the 180th day following the issuing
of the Registrable Securities, such Shelf Registration Statement is not declared
effective (each such event a "Registration Default"), additional interest
("Liquidated Damages") will accrue on the Debentures and, accordingly,
additional distributions will accrue on the Preferred Securities, from and
including the day following such Registration Default until such time as such

                                      28
<PAGE>
 
Shelf Registration Statement is filed or such Shelf Registration Statement is
declared effective, as the case may be. Liquidated Damages will be paid
quarterly in arrears (subject to the Company's ability to defer payment of
Liquidated Damages during any Extension Period), with the first quarterly
payment due on the first Interest Payment Date following the date on which such
Liquidated Damages begin to accrue, and will accrue at a rate per annum equal to
an additional 0.25% of the principal amount, to and including the 90th day
following such Registration Default and 0.50% thereof from and after the 91st
day following such Registration Default. In the event that during the
Effectiveness Period the Shelf Registration Statement ceases to be effective, or
the Company suspends the use of the prospectus which is a part thereof, for more
than 90 days, whether or not consecutive, during any 12-month period then the
interest rate borne by the Debentures and the distribution rate borne by the
Preferred Securities will each increase by an additional 0.50% per annum from
the 91st day of the applicable 12-month period such Shelf Registration Statement
ceases to be effective or the Company suspends the use of the prospectus which
is a part thereof, as the case may be, until the earlier of such time as (i) the
Shelf Registration Statement again becomes effective, (ii) the use of the
related prospectuses ceases to be suspended or (iii) the Effectiveness Period
expires.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Debenture is registrable in the Securities
Register, upon surrender of this Debenture for registration of transfer at the
office or agency of the Company maintained under Section 10.2 of the Indenture
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the Securities Registrar duly executed by, the
Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Debentures, of authorized denominations and for the same aggregate
principal amount, will be issued to the designated transferee or transferees. No
service charge shall be made for any such registration of transfer or exchange,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith.

                                      29

transfer, the Company, the Trustee and any agent of the Company or the Trustee

the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

denominations of $50 and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Debentures are
exchangeable for a like aggregate principal amount of Debentures of a different
authorized denomination, as requested by the Holder surrendering the same.

         The Company and, by its acceptance of this Debenture or a beneficial
interest therein, the Holder of, and any Person that acquires a beneficial
interest in, this Debenture agree that for United States Federal, state and
local tax purposes it is intended that this Debenture constitute indebtedness.

                                 THE DEBENTURES

         SECTION 3.1. Amount of Debentures. The aggregate principal amount of
Debentures which may be authenticated and delivered under this Indenture is
$567,050,000 except for Debentures authenticated and delivered upon registration
of, transfer of, or in exchange for, or in lieu of, other Debentures pursuant to
Sections 3.4, 3.5 or 3.6.

                                      36
<PAGE>
 
         SECTION 3.2. Denominations. The Debentures shall be in registered form
without coupons and shall be issuable in denominations of $50 and any integral
multiple thereof.

         SECTION 3.3. Execution, Authentication, Delivery and Dating. The
Debentures shall be executed on behalf of the Company by its President or one of
its Vice Presidents under its corporate seal reproduced or impressed thereon and
attested by its Secretary or one of its Assistant Secretaries. The signature of
any of these officers on the Debentures may be manual or facsimile.

         Debentures bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Debentures or did not
hold such offices at the date of such Debentures. Upon the execution and
delivery of this Indenture, or from time to time thereafter, Debentures may be
executed by the Company and delivered to the Trustee for authentication, and the
Trustee shall thereupon authenticate and deliver said Securities to or upon
Company Order without any further action by the Company. Debentures may be
authenticated on original issuance from time to time and delivered pursuant to
such procedures acceptable to the Trustee ("Procedures") as may be specified
from time to time by Company Order. Procedures may authorize authentication and
delivery pursuant to oral instructions of the Company or a duly authorized
agent, which instructions shall be promptly confirmed in writing.

         Each Debenture shall be dated the date of its authentication.

         No Debenture shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose, unless there appears on such Debenture a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
officers, and such certificate upon any Debenture shall be conclusive evidence,
and the only evidence, that such Debenture has been duly authenticated and
delivered hereunder.

         SECTION 3.4. Temporary Debentures. Pending the preparation of
definitive Debentures, the Company may execute, and upon Company Order the
Trustee shall authen-

                                      37
<PAGE>
 
ticate and deliver, temporary Debentures which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any denomination,
substantially of the tenor of the definitive Debentures in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Debentures may determine, as
evidenced by their execution of such Debentures.

         If temporary Debentures are issued, the Company will cause definitive
Debentures to be prepared without unreasonable delay. After the preparation of
definitive Debentures, the temporary Debentures shall be exchangeable for
definitive Debentures upon surrender of the temporary Debentures at the office
or agency of the Company designated for the purpose without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Debentures,
the Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a like principal amount of definitive Debentures of authorized
denominations. Until so exchanged, the temporary Debentures shall in all
respects be entitled to the same benefits under this Indenture as definitive
Debentures.

         SECTION 3.5. Registration, Transfer and Exchange. The Company shall
cause to be kept at the Corporate Trust Office of the Trustee a register in
which, subject to such reasonable regulations as it may prescribe, the Company
shall provide for the registration of Debentures and of transfers of Debentures.
Such register is herein sometimes referred to as the "Securities Register." The
Trustee is hereby appointed "Securities Registrar" for the purpose of
registering Debentures and transfers of Debentures as herein provided.

         Upon surrender for registration of transfer of any Debenture at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Debentures of any
authorized denominations, of a like aggregate principal amount.

         At the option of the Holder, Debentures may be exchanged for other
Debentures of any authorized denominations, of a like aggregate principal
amount, upon surrender of the Debentures to be exchanged at such office or
agency. Whenever any Debentures are so surrendered for exchange, the Company
shall execute, and the

                                      38
<PAGE>
 
Trustee shall authenticate and deliver, the Debentures which the Holder making
the exchange is entitled to receive.

         All Debentures issued upon any transfer or exchange of Debentures shall
be the valid obligations of the Company, evidencing the same debt, and entitled
to the same benefits under this Indenture, as the Debentures surrendered upon
such transfer or exchange.

         Every Debenture presented or surrendered for transfer or exchange shall
(if so required by the Company or the Securities Registrar) be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing.

         No service charge shall be made to a Holder for any transfer or
exchange of Debentures, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Debentures.

         Notwithstanding any of the foregoing, the Global Debenture shall be
exchangeable pursuant to this Section 3.5 for Debentures registered in the names
of Persons other than the Depositary for such Debenture or its nominee only if
(a) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for the Global Debenture and the Company shall not have
appointed a successor depositary within 90 days after such notice, or if at any
time such Depositary ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, (b) the Company executes and
delivers to the Trustee a Company Order that the Global Debenture shall be so
exchangeable or (c) there shall have occurred and be continuing an Event of
Default. The Global Debenture shall be exchangeable for Debentures registered in
such names as such Depositary shall direct.

         Notwithstanding any other provisions in this Indenture, the Global
Debenture may not be transferred except as a whole by the Depositary with
respect to the Global Debenture to a nominee of such Depositary or by a nominee
of such Depositary to such Depositary or another nominee of such Depositary.

                                      39
<PAGE>
 
         Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, transfer or exchange any Debenture
during a period beginning at the opening of business 15 days before the day of
selection for redemption of Debentures pursuant to Article 11 and ending at the
close of business on the day of mailing of notice of redemption or (b) to
transfer or exchange any Debenture so selected for redemption in whole or in
part, except, in the case of any Debenture to be redeemed in part, any portion
thereof not to be redeemed.

         The Debentures may not be transferred except in compliance with the
Restricted Securities Legend unless otherwise determined by the Company in
accordance with applicable law. Upon any distribution of the Debentures to the
holders of the Preferred Securities in accordance with the Trust Agreement, the
Company and the Trustee shall enter into a supplemental indenture pursuant to
Section 9.1(h) to provide for transfer procedures and restrictions with respect
to the Debentures substantially similar to those contained in the Trust
Agreement to the extent applicable in the circumstances existing at the time of
such distribution.

         SECTION 3.6. Mutilated, Destroyed, Lost and Stolen Debentures. If any
mutilated Debenture is surrendered to the Trustee together with such security or
indemnity as may be required by the Company or the Trustee to save each of them
harmless, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Debenture and bearing a number not
contemporaneously outstanding.

         If there shall be delivered to the Company and to the Trustee (a)
evidence to their satisfaction of the destruction, loss or theft of any
Debenture, and (b) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of actual notice to the Company or
the Trustee that such Debenture has been acquired by a bona fide purchaser, the
Company shall execute and upon a Company Order its request the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen
Debenture, a new Debenture bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Debenture has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Debenture, pay such Debenture.

                                      40
<PAGE>
 
         Upon the issuance of any new Debenture under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Debenture issued pursuant to this Section in lieu of any
destroyed, lost or stolen Debenture shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Debenture shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Debentures duly issued hereunder.

         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Debentures.

         SECTION 3.7. Payment of Interest; Interest Rights Preserved. Interest
on any Debenture which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date, shall be paid to the Person in whose name that
Debenture (or one or more Predecessor Debentures) is registered at the close of
business on the Regular Record Date, except that interest payable on the Stated
Maturity of the Debentures shall be paid to the Person to whom principal is
paid.

         Any interest on the Debentures which is payable, but is not timely paid
or duly provided for, on an Interest Payment Date (herein called "Defaulted
Interest"), shall forthwith cease to be payable to the registered Holder on the
Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in clause (a) or (b) below:

                  (a) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Debentures (or their
         respective Predecessors Debentures) are registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed to be paid on the Debentures and the date of the proposed
         payment, and at the same time

                                      41
<PAGE>
 
         the Company shall deposit with the Trustee an amount of money equal to
         the aggregate amount proposed to be paid in respect of such Defaulted
         Interest or shall make arrangements satisfactory to the Trustee for
         such deposit prior to the date of the proposed payment, such money when
         deposited to be held in trust for the benefit of the Persons entitled
         to such Defaulted Interest as in this Clause provided. Thereupon the
         Trustee shall fix a Special Record Date for the payment of such
         Defaulted Interest which shall be not more than 15 days and not less
         than 10 days prior to the date of the proposed payment and not less
         than 10 days after the receipt by the Trustee of the notice of the
         proposed payment. The Trustee shall promptly notify the Company of such
         Special Record Date and, in the name and at the expense of the Company,
         shall cause notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor to be mailed, first class, postage
         prepaid, to each Holder of the Debentures at the address of such Holder
         as it appears in the Securities Register not less than 10 days prior to
         such Special Record Date. Notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor having been
         mailed as aforesaid, such Defaulted Interest shall be paid to the
         Persons in whose names the Debentures (or their respective Predecessor
         Debentures) are registered on such Special Record Date and shall no
         longer be payable pursuant to the following clause (b).

                  (b) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Debentures may be listed and, upon
         such notice as may be required by such exchange (or by the Trustee if
         the Debentures are not listed), if, after notice given by the Company
         to the Trustee of the proposed payment pursuant to this Clause, such
         payment shall be deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section, each Debenture
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Debenture shall carry the rights to interest accrued and unpaid, and
to accrue, which were carried by such other Debenture.

                                      42
<PAGE>
 
         SECTION 3.8. Persons Deemed Owners. The Company, the Trustee, the
Paying Agent and any agent of the Company or the Trustee or the Paying Agent may
treat the Person in whose name any Debenture is registered as the owner of such
Debenture for the purpose of receiving payment of principal of and (subject to
Section 3.7) interest on such Debenture and for all other purposes whatsoever,
whether or not such Debenture be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.

         SECTION 3.9. Cancellation. All Debentures surrendered for payment,
redemption, conversion transfer or exchange shall, if surrendered to any Person
other than the Trustee, be delivered to the Trustee, and any such Debentures and
Debentures surrendered directly to the Trustee for any such purpose shall be
promptly canceled by it. The Company may at any time deliver or cause to be
delivered to the Trustee for cancellation any Debentures previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Debentures so delivered shall be promptly canceled by
the Trustee. No Debentures shall be authenticated in lieu of or in exchange for
any Debentures canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Debentures shall be destroyed by the
Trustee and upon request, the Trustee shall deliver to the Company a certificate
of such destruction.

         SECTION 3.10. Computation of Interest. Interest on the Debentures shall
be computed on the basis of a 360-day year of twelve 30-day months.

         SECTION 3.11. Deferrals of Interest Payment Dates. The Company shall
have the right, at any time during the term of the Debentures, so long as no
Event of Default has occurred and is continuing, from time to time to extend the
interest payment period for the Debentures for up to 20 consecutive quarters
with respect to each deferral period (each, an "Extension Period") during which
periods the Company shall have the right to not make payments of interest
(including any Liquidated Damages) on any Interest Payment Date, and at the end
of such Extension Period the Company shall pay all interest then accrued and
unpaid thereon (together with Additional Interest thereon, if any, at the rate
specified for the Debentures to the extent permitted by applicable law),
provided, however, that during any such Extension Period,

                                      43
<PAGE>
 
the Company shall not, and shall cause any Subsidiary not to, (a) declare or pay
any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any shares of the Company's capital stock
or (b) make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities (including guarantees of indebtedness
for money borrowed) of the Company that rank pari passu with or junior to the
Debentures (other than (i) any dividend, redemption, liquidation, interest,
principal or guarantee payment by the Company where the payment is made by way
of securities (including capital stock) that rank pari passu with or junior to
the securities on which such dividend, redemption, interest, principal or
guarantee payment is being made, (ii) redemptions or purchases of any rights
pursuant to the Company's Shareholders Rights Plan, or any successor to such
Shareholders Rights Plan, and the declaration of a dividend of such rights or
the issuance of preferred stock under such plans in the future, (iii) payments
under the Guarantee, (iv) purchases of Common Stock related to the issuance of
Common Stock under any of the Company's benefit plans for its directors,
officers or employees, (v) as a result of a reclassification of the Company's
capital stock or the exchange or conversion of one series or class of the
Company's capital stock for another series or class of the Company's capital
stock and (vi) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged). Prior to the termination of
any such Extension Period, the Company may further extend the interest payment
period, provided that no such Extension Period shall exceed 20 consecutive
quarters or extend beyond the Stated Maturity of the Debentures. Upon
termination of any Extension Period and upon the payment of all accrued and
unpaid interest and any Additional Interest then due, the Company may select a
new Extension Period, subject to the above requirements. No interest including
Additional Interest and Liquidated Damages, if any, shall be due and payable
during an Extension Period, except at the end thereof. The Company shall give
the Trustee, the Property Trustee and the Administrative Trustees notice of its
selection of such Extension Period at least one Business Day prior to the
earlier of (i) the record date for the date the distributions on the Preferred
Securities of the Trust (or if no, Preferred Securities are outstanding, for the
date interest on the Debentures) would have been payable except for the election
to begin such Extension Period and (ii) the date the Property Trustee (or, if no

                                      44
<PAGE>
 
Preferred Securities are outstanding, the Trustee) is required to give notice to
NYSE or other applicable self-regulatory organization or to holders of such
Preferred Securities (or, if no Preferred Securities are outstanding, to the
holders of such Debentures) of such record date, but in any event not less than
one Business Day prior to such record date. Such notice shall specify the period
selected.

         The Trustee shall promptly give notice of the Company's selection of
such Extension Period to the Holders of the outstanding Debentures.

         SECTION 3.12. Right of Set-off. Notwithstanding anything to the
contrary in the Indenture, the Company shall have the right to set-off any
payment it is otherwise required to make thereunder in respect of the Debenture
to the extent the Company has theretofore made, or is concurrently on the date
of such payment making, a payment relating to the Debentures under the
Guarantee.

         SECTION 3.13. Agreed Tax Treatment. Each Debenture issued hereunder
shall provide that the Company and, by its acceptance of a Debenture or a
beneficial interest therein, the Holder of, and any Person that acquires a
beneficial interest in, such Debenture agree that for United States Federal,
state and local tax purposes it is intended that such Debenture constitute
indebtedness.

         SECTION 3.14. CUSIP Numbers. The Company in issuing the Debentures may
use "CUSIP" numbers (if then generally in use), and, if so, the Trustee shall
use such "CUSIP" number in notices of redemption as a convenience to Holders;
provided that any such notice may state that no representation is made as to the
correctness of such number either as printed on the Debentures or as contained
in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Debentures, and any such redemption shall
not be affected by any defect in or omission of such numbers.

         SECTION 3.15. Global Security.  (a)  In connection with distribution of
Debentures to holders of the Preferred Securities in connection with the
involuntary or voluntary dissolution, winding up or liquidation of the Trust,

                           (i)   the Debentures in certificated form may be
presented to the Trustee by the Property Trustee

                                      45
<PAGE>
 
in exchange for a global certificate in an aggregate principal amount equal to
the aggregate principal amount of all outstanding Debentures (a "Global
Debenture"), to be registered in the name of the Depositary, or its nominee, and
delivered by the Trustee to the Depositary, or its custodian, for crediting to
the accounts of its participants pursuant to the procedures of the Depositary.
The Company upon any such presentation shall execute a Global Debenture in such
aggregate principal amount and deliver the same to the Trustee for
authentication and delivery in accordance with this Indenture; and

                           (ii)      if any Preferred Securities are held
in non book-entry certificated form, the Debentures in certificated form may be
presented to the Trustee by the Property Trustee and any Preferred Security
certificate which represents Preferred Securities other than Preferred
Securities held by the Depositary or its nominee ("Non Book-Entry Preferred
Securities") will be deemed to represent beneficial interests in Debentures
presented to the Trustee by the Property Trustee having an aggregate principal
amount equal to the aggregate liquidation amount of the Non Book-Entry Preferred
Securities until such Preferred Security certificates are presented to the
Securities Registrar for transfer or reissuance at which time such Non-Book
Entry Preferred Security certificates will be cancelled and a Debenture,
registered in the name of the holder of the Preferred Security certificate or
the transferee of the holder of such Preferred Security certificate, as the case
may be, with an aggregate principal amount equal to the aggregate liquidation
amount of the Preferred Security certificate cancelled, will be executed by the
Company and delivered to the Trustee for authentication and delivery in
accordance with this Indenture. On issue of such Debentures, Debentures with an
equivalent aggregate principal amount that were presented by the Property
Trustee to the Trustee will be deemed to have been cancelled.

                  (b) A Global Debenture may be transferred, in whole but not in
part, only to another nominee of the Depositary, or to a nominee of such
successor Depositary.

                  (c) If (i) the Depositary notifies the Company that it is
unwilling or unable to continue as a depositary for such Global Debenture and
no successor depositary shall have been appointed within 90 days by the
Company, (ii) the Depositary, at any time, ceases to be a clearing agency
registered under the Exchange Act at which time the Depositary is required to be
so registered

                                      46
<PAGE>
 
to act as such depositary and no successor depositary shall have been appointed
within 90 days by the Company, (iii) the Company, in its sole discretion,
determines that such Global Debenture shall be so exchangeable or (iv) there
shall have occurred an Event of Default with respect to such Debentures, as the
case may be, the Company will execute, and, subject to Article 3 of this
Indenture, the Trustee, upon written notice from the Company and receipt of a
Company Order, will authenticate and deliver the Debentures in definitive
registered form without coupons, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Debenture
in exchange for such Global Debenture. In addition, upon an Event of Default or
if the Company may at any time determine that the Debenture shall no longer be
represented by a Global Debenture, in such event the Company will execute, and
subject to Section 3.5 of this Indenture, the Trustee, upon receipt of an
Officers' Certificate evidencing such determination by the Company and a Company
Order, will authenticate and make available for delivery the Debentures in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Debenture in exchange for such Global Debenture. Upon the exchange of the Global
Debenture for such Debentures in definitive registered form without coupons, in
authorized denominations, the Global Debenture shall be cancelled by the
Trustee. Such Debentures in definitive registered form issued in exchange for
the Global Debenture shall be registered in such names and in such authorized
denominations as the Depositary, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such Debentures to the Depositary for delivery to the Persons in
whose names such Debentures are so registered.

                  entire indebtedness on the Debentures not theretofore
                  delivered to the Trustee for cancellation, for principal (and

         Certificate and an Opinion of Counsel each stating that all conditions

obligations have been deposited with or received by the Trustee; provided,
however, such moneys need not be segregated from other funds except to the
extent required by law.

         has been expressly included in this Indenture solely for the benefit of
         the Company) and continuance for such failure for a period of 90 days
         after the date on which written notice of such failure, requiring the
         same to be remedied and stating that such notice is a "Notice of

         appointment of a receiver, liquidator, assignee, trustee, seques-
         trator (or other similar official) of the Company or of any substantial

         benefit of creditors, or the admission by it in writing of its
         inability to pay its debts generally as they become due and its
         willingness to be adjudicated as bankrupt, or the taking of corporate
         action by the Company in furtherance of any such action.

         SECTION 5.2. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures may declare the principal amount of all the Debentures to
be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders), provided that, if upon an Event of Default,
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures fail to declare the principal of all 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 Company and the Trustee, and upon any such
declaration such principal amount (or specified amount) of and the accrued
interest (including any Additional Interest) on all the Debentures shall become
immediately due and payable, provided that the payment of principal and interest
(including any Additional Interest) on the Debentures shall remain subordinated
to the extent provided in Article 12.

         At any time after such a declaration of acceleration with respect to
Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in principal amount of the Outstanding
Debentures, by written notice to the Company and the Trustee may rescind and
annul such declaration and its consequences if:

                  (i)  the Company has paid or deposited with the Trustee a sum
         sufficient to pay

                                      51
<PAGE>
 
                           (A) all overdue installments of interest (including
                  any Additional Interest) on the Debentures;

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

                           (C) to the extent that payment of such interest is
                  lawful, interest (including any Additional Interest) upon
                  overdue installments of interest at the rate borne by the
                  Debentures;

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel; and

         (ii)   all Events of Default with respect to 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. If the
holders of a majority in principal amount of the Outstanding Debentures fail to
rescind and annul such declaration and its consequences, the holders of a
majority in liquidation amount of the Preferred Securities then outstanding
shall have such right.

         SECTION 5.3. Collection of Indebtedness and Suits for Enforcement by
Trustee.

         The Company covenants that if:

         (a) default is made in the payment of any installment of interest
(including any Additional Interest) on the Debentures when such interest becomes
due and payable and such default continues for a period of 30 days, or

         (b) default is made in the payment of the principal of (and premium, if
any, on) the Debentures whether at the Stated Maturity thereof upon redemption
by declaration or otherwise, the Company will, upon demand of the Trustee, pay
to it, for the benefit of the Holders of the Debentures, the whole amount then
due and payable on the Debentures for principal (and premium, if any) and
interest (including any Additional Interest), including, to the extent that
payment of such interest shall be lawful,

                                      52
<PAGE>
 
interest on any overdue principal (and premium, if any) and on any overdue
installments of interest (including any Additional Interest) at the rate borne
by the Debentures, and, in addition thereto, all amounts owing the Trustee under
Section 6.7.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgement or final decree, and may enforce the same
against the Company or any other obligor upon the Debentures and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Debentures, wherever
situated.

         If an Event of Default occurs and is continuing, the Trustee may in its
discretion proceed to protect and enforce its rights and the rights of the
Holders of the Debentures by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

         SECTION 5.4. Trustee May File Proofs of Claim. In case of the pendency
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to
the Company or any other obligor upon the Debentures or the property of the
Company or of such other obligor or their creditors:

         (a)   the Trustee (irrespective of whether the principal of the
Debentures shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of overdue principal (and premium, if any) or
interest (including any Additional Interest)) shall be entitled and empowered,
by intervention in such proceeding or otherwise,

               (i) to file and prove a claim for the whole amount of principal
         (and premium, if any) and interest (including any Additional Interest)
         owing and unpaid in respect to the Debentures and to file such other
         papers or documents as may be necessary or

                                      53
<PAGE>
 
         advisable and to take any and all actions as are authorized under the
         Trust Indenture Act in order to have the claims of the Holders and any
         predecessor to the Trustee under Section 6.7 and, of the Holders
         allowed in any such judicial proceedings; and

                  (ii) in particular, the Trustee shall be authorized to collect
         and receive any moneys or other property payable or deliverable on any
         such claims and to distribute the same in accordance with Section 5.6;
         and

         (b) any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

         SECTION 5.5. Trustee May Enforce Claim Without Possession of
Debentures. All rights of action and claims under this Indenture or the
Debentures may be prosecuted and enforced by the Trustee without the possession
of any of the Debentures or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgement
shall, after provision for the payment of all the amounts owing the Trustee and
any predecessor Trustee under Section 6.7, its agents and counsel, be for the
ratable benefit of the Holders of the Debentures in respect of which such
judgement has been recovered.

         SECTION 5.6. Application of Money Collected. Any money or property
collected or to be applied by the Trustee with respect to the Debentures
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money or
property on account of principal (or premium, if any) or interest (including any
Additional Interest), upon presentation of the Debentures and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

         FIRST: To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7,

         SECOND: To the payment of the amounts then due and unpaid upon the
Debentures for principal (and premium, if any) and interest (including any
Additional Interest), in respect of which or for the benefit of which such money
has been collected, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Debentures for principal (and
premium, if any) and interest (including any Additional Interest), respectively;
and

         THIRD: The balance, if any, to the Person or Persons entitled thereto.

         SECTION 5.7. Limitation on Suits. No Holder of the Debentures,
including a holder of Preferred Securities acting to enforce the rights of the
Property Trustee as a Holder of the Debentures pursuant to Section 6.8 of the
Trust Agreement, shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture or for the appointment of a receiver,
assignee, trustee, liquidator, sequestrator (or other similar official) or for
any other remedy hereunder, unless:

                  (a)  such Holder has previously given written notice to the
         Trustee of a continuing Event of Default;

                  (b)  if the Trust is not the sole holder of the Outstanding
         Debentures, the Holders of not less than 25% in principal amount of the
         Outstanding Debentures shall have made written request to the Trustee
         to institute proceedings in respect of such Event of Default in its own
         name as Trustee hereunder;

                  (c)  such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs,

                                      55
<PAGE>
 
         expenses and liabilities to be incurred in compliance with such
         request;

                  (d) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (e) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Debentures;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of the Debentures, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

         SECTION 5.8. Unconditional Right of Holders to Receive Principal,
Premium and Interest. Notwithstanding any other provision in this Indenture, the
Holder of any Debenture shall have the right which is absolute and unconditional
to receive payment of the principal of (and premium, if any) and (subject to
Section 3.7) interest (including any Additional Interest) on such Debenture on
the Maturity or to convert such Debenture in accordance with Article 13 and to
institute suit for the enforcement of any such payment and right to convert, and
such right shall not be impaired without the consent of such Holder. For so long
as any Preferred Securities remain Outstanding, to the fullest extent permitted
by law and subject to the terms of this Indenture and the Trust Agreement, upon
an Event by Default specified in Sections 5.1(a) or 5.1(b), any holder of
Preferred Securities shall have the right to institute a proceeding directly
against the Company, for enforcement of payment to such holder of the principal
amount of or interest on Debentures having a principal amount equal to the
liquidation preference of the Preferred Securities of such holder (a "Direct
Action"). Notwithstanding any payment made to such holder of Preferred
Securities by the Company in connection with a Direct Action, the Company shall
remain obligated to pay the principal of or interest on the Debentures held by
the Trust or the Property Trustee. In connection with

                                      56
<PAGE>
 
any such Direct Action, the rights of the Company will be subrogated to the
rights of any holder of the Preferred Securities to the extent of any payment
made by the Company to such holder of Preferred Securities as a result of such
Direct Action. Except as set forth in this Section, the holders of Preferred
Securities shall have no right to execute any right or remedy available to the
Holders of or in respect of, the Debentures.

         SECTION 5.9. Restoration of Rights and Remedies. If the Trustee or any
Holder has instituted any proceeding to enforce any right or remedy under this
Indenture and such proceeding has been discontinued or abandoned for any reason,
or has been determined adversely to the Trustee or to such Holder, then and in
every such case the Company, the Trustee and the Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

         SECTION 5.10. Rights and Remedies Cumulative. Except as otherwise
provided in the last paragraph of Section 3.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         SECTION 5.11. Delay or Omission Not Waiver. No delay or omission of the
Trustee or of any Holder of the Debentures to exercise any right or remedy
accruing upon any Event of Default shall impair any such right or remedy, or
constitute a waiver of any such Event of Default or an acquiescence therein.

         Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

         SECTION 5.12. Control by Holders. The Holders of a majority in
principal amount of the Outstanding Deben-

                                      57
<PAGE>
 
tures shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on the Trustee, with respect to the Debentures, provided
that:

                  (a)  such direction shall not be in conflict with any rule of
         law or with this Indenture,

                  (b)  the Trustee may take any other action deemed proper by
         the Trustee which is not inconsistent with such direction, and

                  (c) subject to the provisions of Section 6.1, the Trustee
         shall have the right to decline to follow such direction if the Trustee
         in good faith shall, by a Responsible Officer or Officers of the
         Trustee, determine that the proceeding so directed would be unjustly
         prejudicial to the Holders not joining in any such direction or would
         involve the Trustee in personal liability.

         Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, with respect to the Debentures and, if all or part of the Debentures
is represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Debentures entitled to join in such notice,
which record date shall be at the close of business on the day the 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 the Holders of a majority in principal amount of the Outstanding
Debentures shall have joined in such notice prior to the day which is 90 days
after such record date, such notice 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 notice identical to a 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 5.12.

         SECTION 5.13. Waiver of Past Defaults. Subject to Section 9.2 hereof,
the Holders of not less than a major-ity in principal amount of the Outstanding
Debentures may

                                      58
<PAGE>
 
on behalf of the Holders of all the Debentures waive any past default hereunder
with respect to Debentures and its consequences, except a default:

                  (a) in the payment of the principal of (or premium, if any) or
         interest (including any Additional Interest) on the Debentures (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 Trustee), or

                  (b) in respect of a covenant or provision hereof which under
         Article 9 cannot be modified or amended without the consent of the
         Holder of each Outstanding Debenture; provided, however, that if the
                                               --------  -------
         Debentures are held by the Trust or a trustee of the Trust, such waiver
         shall not be effective until the holders of a majority in liquidation
         amount of Trust Securities shall have consented to such waiver;
         provided, further, that if the consent of the Holder of each
         --------  -------
         outstanding Debenture is required, such waiver shall not be effective
         until each holder of the Trust Securities shall have consented to such
         waiver.

         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture, but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon. If the Holders of a
majority in aggregate principal amount of the Outstanding Debentures fail to
waive such Event of Default, the holders of a majority in aggregate liquidation
amount of Preferred Securities shall have such right. No such rescission shall
affect any subsequent default or impair any right consequent thereon.

         SECTION 5.14. Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Debenture by his acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,

                                      59
<PAGE>
 
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Debentures, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium, if any) or interest
(including any Additional Interest) on the Debentures on or after the Maturity
of the Debentures or to convert a Debenture in accordance with Article 13.

         SECTION 5.15. Waiver of Usury, Stay, or Extension Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

                                  THE TRUSTEE

         SECTION 6.1. Certain Duties and Responsibilities. (a) Except during the
continuance of an Event of Default,

                           (i) the Trustee undertakes to perform such duties and
                  only such duties as are specifically set forth in this
                  Indenture, and no implied covenants or obligations shall be
                  read into this Indenture against the Trustee; and

                           (ii) in the absence of bad faith on its part, the
                  Trustee may conclusively rely, as to the truth of the
                  statements and the correctness of the opinions expressed
                  therein, upon certificates or opinions furnished to the
                  Trustee and conforming to the requirements of this Indenture,
                  but in the case of any such certificates

                                      60
<PAGE>
 
                  or opinions which by any provisions hereof are specifically
                  required to be furnished to the Trustee, the Trustee shall be
                  under a duty to examine the same to determine whether or not
                  they conform to the requirements of this Indenture.

                  (b) In case an Event of Default has occurred and is
         continuing, the Trustee shall exercise such of the rights and powers
         vested in it by this Indenture, and use the same degree of care and
         skill in their exercise, as a prudent person would exercise or use
         under the circumstances in the conduct of his own affairs.

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

                           (i)   this Subsection shall not be construed to
                  limit the effect of Subsection (a) of this Section;

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

                           (iii) the 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 Holders pursuant to Section
                  5.12 relating to the time, method and place of conducting any
                  proceeding for any remedy available to the Trustee, or
                  exercising any trust or power conferred upon the Trustee,
                  under this Indenture.

                  (d) No provision of this Indenture shall require the Trustee
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if there shall be reasonable
         grounds for believing that repayment of such funds or adequate
         indemnity against such risk or liability is not reasonably assured to
         it.

                                      61
<PAGE>
 
                  (e) Whether or not therein expressly so provided, every
         provision of this Indenture relating to the conduct or affecting the
         liability of or affording protection to the Trustee shall be subject to
         the provisions of this Section.

         SECTION 6.2. Notice of Defaults. Within 90 days after actual knowledge
by a Responsible Officer of the Trustee of the occurrence of any default
hereunder, the Trustee shall transmit by mail to all Holders of Debentures, as
their names and addresses appear in the Securities Register, notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest (including any
Additional Interest) on Debenture, the Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee or
a trust committee of directors and/or Responsible Officers of the Trustee in
good faith determines that the withholding of such notice is in the interests of
the Holders of Debentures; and provided, further, that, except in the case of
                               --------  -------
any default of the character specified in Section 5.1(c), no such notice to
Holders of the Debentures shall be given until at least 30 days after the
occurrence thereof For the purpose of this Section, the term "default" means any
event which is, or after notice or lapse of time or both would become, an Event
of Default.

         SECTION 6.3. Certain Rights of Trustee. Subject to the provisions of
Section 6.1:

                  (a) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, Debenture or other paper or document believed
         by it to be genuine and to have been signed or presented by the proper
         party or parties;

                                      62

         matter be proved or established prior to taking, suffering or omitting
         any action hereunder, the Trustee (unless other evidence be herein
         specifically prescribed) may, in the absence of bad faith on its part,

         incurred by it in compliance with such request or direction;

                  (f) the Trustee is not required to expend or risk its own

                  (g) the 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, direction,
         consent, order, bond, indenture, Debenture or other paper or document,

         SECTION 6.4. Not Responsible for Recitals or Issuance of Debentures.
The recitals contained herein and in the Debentures, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness. The Trustee

of the Debentures. The Trustee shall not be accountable for the use or
application by the Company of the Debentures or the proceeds thereof.

         SECTION 6.5. May Hold Debentures. The Trustee, any Paying Agent,
Securities Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Debentures and, subject to
Sections 6.8 and 6.13, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Paying Agent, Securities Registrar or such
other agent.

         SECTION 6.6. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required

         compensation for all services rendered by it hereunder in such amounts
         as the Company and the Trustee shall agree from time to time (which
         compensation shall not be limited by any provision of law in regard to
         the compensation of a trustee of an express trust);

                  (b) to reimburse the Trustee upon its request for all
         reasonable expenses, disbursements and advances incurred or made by the
         Trustee in accordance with any provision of this Indenture (including
         the reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursements of its
         agents and counsel); and

                  (c)  to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense (including the reasonable
         compensation and the

                                      64
<PAGE>
 
         expenses and disbursements of its agents and counsel) incurred without
         negligence or bad faith, arising out of or in connection with the
         acceptance or administration of this trust or the performance of its
         duties hereunder, including the costs and expenses of defending itself
         against any claim or liability in connection with the exercise or
         performance of any of its powers or duties hereunder. This
         Indemnification shall survive the termination of this Agreement.

         To secure the Company's payment obligations in this Section, the
Company and the Holders agree that the Trustee shall have a lien prior to the
Debentures on all money or property held or collected by the Trustee except
assets held in trust to pay principal and premium, if any, or interest on
particular Debentures pursuant to Section 4.1(a)(ii)(B), or pursuant to any
redemption pursuant to Article 11 hereof if monies have been deposited for such
redemption and notice has been given and the Redemption Date has passed. Such
lien shall survive the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(e) or (f) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Reform Act of 1978 or a successor statute.

         SECTION 6.8. Disqualification; Conflicting Interests. The Trustee shall
be subject to the provisions of Section 310(b) of the Trust Indenture Act.
Nothing herein shall prevent the Trustee from filing with the Commission the
application referred to in the second to last paragraph of Section 310(b) of the
Trustee Indenture Act. The Trust Agreement and the Guarantee shall be deemed to
be specifically described in this Indenture for the purposes of clause (i) of
the first proviso contained in Section 310(b) of the Trust Indenture Act.

         SECTION 6.9. Corporate Trustee Required; Eligibili-ty. There shall at
all times be a Trustee hereunder which shall be

                  (a) a corporation organized and doing business under the laws
         of the United States of America or of any State, Territory or the
         District of Columbia, authorized under such laws to exercise corporate
         trust powers and subject to supervision or examina-

                                      65

         under the laws of a foreign government that is permitted to act as
         Trustee pursuant to a rule, regulation or order of the Commission,
         authorized under such laws to exercise corporate trust powers, and
         subject to supervision or examination by authority of such foreign
         government or a political subdivision thereof substantially equivalent
         to supervision or examination applicable to United States institutional
         trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by Federal or State authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then,
to the purposes of this Section, the combined capital and surplus of such
corporation 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 Trustee
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. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve
as Trustee hereunder.

         SECTION 6.10. Resignation and Removal; Appointment of Successor. (a) No
resignation or removal of the Trustee and no appointment of a successor Trustee
pursu-ant to this Article shall become effective until the acceptance of
appointment by the successor Trustee under Section 6.11.

                  (b) The Trustee may resign at any time by giving written
         notice thereof to the Company. If an instrument of acceptance by a
         successor Trustee shall not have been delivered to the Trustee within
         30 days after the giving of such notice of resignation, the resigning
         Trustee may petition any court of competent jurisdiction for the
         appointment of a successor Trustee.

                  (c)  The Trustee may be removed at any time by Act of the
         Holders of a majority in principal amount

                                      66
<PAGE>
 
         of the Outstanding Debentures, delivered to the Trustee and to the
         Company.

                  (d)      If at any time:
  
                           (i)   the Trustee shall fail to comply with Section
                  6.8 after written request therefor by the Company or by any
                  Holder who has been a bona fide Holder of a Debenture for at
                  least six months, or

                           (ii)  the Trustee shall cease to be eligible under
                  Section 6.9 and shall fail to resign after written request
                  therefor by the Company or by any such Holder, or

                           (iii) the Trustee shall become incapable of acting or
                  shall be adjudged as bankrupt or insolvent or a receiver of

                  of its property or affairs for the purpose of rehabilitation,
                  conservation or liquidation,

then, in any such case, (A) the Company by Board Resolution may remove the
Trustee, or (B) subject to Section 5.14, any Holder who has been a bona fide
Holder of a Debenture for at least six months may, on behalf of himself and all
other similarly situated Holders, petition any court of competent jurisdiction

                  (e) If the Trustee shall resign, be removed or become
         incapable of acting, or if a vacancy shall occur in the office of
         Trustee for any cause with respect to the Debentures, the Company, by a
         Board Resolution, shall promptly appoint a successor Trustee. If,
         within one year after such resignation, removal or incapability, or the
         occurrence of such vacancy, a successor Trustee with respect to the
         Debentures shall be appointed by Act of the Holders of a majority in
         principal amount of the Outstanding Debentures delivered to the Company
         and the retiring Trustee, the successor Trustee so appointed shall,
         forthwith upon its acceptance of such appointment, become the successor
         Trustee and supersede the successor Trustee appointed by the Company.
         If no successor Trustee shall have been so

                                      67
<PAGE>
 
         appointed by the Company or the Holders and accepted appointment in the
         manner hereinafter provided, any Holder who has been a bona fide Holder
         of a Debenture for at least six months may, subject to Section 5.14, on
         behalf of himself and all others similarly situated, petition any court
         of competent jurisdiction for the appointment of a successor Trustee.

                  (f) The Company shall give notice of each resignation and each
         removal of the Trustee and each appointment of a successor Trustee by
         mailing written notice of such event by first-class mail, postage
         prepaid, to the Holders of the Debentures as their name and addresses
         appear in the Securities Register. Each notice shall include the name
         of the successor Trustee and the address of its Corporate Trust Office.

         SECTION 6.11. Acceptance of Appointment by Successor. (a) In case of
the appointment hereunder of a successor Trustee, every such successor Trustee
so appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee,
but, on the request of the Company or the Successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor, Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

                  (b) Upon request of any such successor Trustee, the Company
         shall execute any and all instruments for more fully and certainly
         vesting in and confirming to such successor Trustee all rights, power
         and trusts referred to in paragraph (a) of this Section.

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

         SECTION 6.12. Merger, Conversion, Consolidation or Succession to
Business. Any corporation into which the

                                      68
<PAGE>
 
Trustee may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any corporation succeeding to all or substantially
all of the corporate trust business of the Trustee, shall be the successor of
the 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. In case any Debentures
shall have been authenticated, but not delivered, by the Trustee then in office,
any successor by merger, conversion or consolidation to such authenticating
Trustee may adopt such authentication and deliver the Debentures so
authenticated, and in case any Debentures shall not have been authenticated, any
successor to the Trustee may authenticate such Debentures either in the name of
any predecessor Trustee or in the name of such successor Trustee, and in all
cases the certificate of authentication shall have the full force which it is
provided anywhere in the Debentures or in this Indenture that the certificate of
the Trustee shall have.

         SECTION 6.13. Preferential Collection of Claims Against Company. If and
when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Debentures), the Trustee shall be subject to the provisions of
the Trust Indenture Act regarding the collection of claims against the Company
(or any such other obligor).

         SECTION 6.14. Appointment of Authenticating Agent. The Trustee may
appoint an Authenticating Agent or Agents with respect to the Debentures which
shall be authorized to act on behalf of the Trustee to authenticate the
Debentures issued upon exchange, registration of transfer or partial redemption
thereof, and Debentures so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Debentures by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and doing business
under the laws of the United States of America, or of any State, Territory or
the District of Columbia, authorized under such laws to act as Authenti-

                                      69
<PAGE>
 
cating Agent, having a combined capital and surplus of not less than $50,000,000
and subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section the combined capital and surplus of such
Authenticating Agent 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 an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent shall be the successor
Authenticating Agent hereunder, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of the
Debentures. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent. No successor Authenticating Agent shall be appointed
unless eligible under the provision of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section, and the
Trustee shall be

                                      70
<PAGE>
 
entitled to be reimbursed for such payments, subject to the provisions of
Section 6.7.

         If an appointment is made pursuant to this Section, the Debentures may
have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternative certificate of authentication in the following
form:

         This is one of the Debentures referred to in the within mentioned
indenture.

         nor the Trustee nor any agent of either of them shall be held
         accountable by reason of the disclosure of information as to the names
         and addresses of the Holders made pursuant to the Trust Indenture Act.

         SECTION 7.3. Reports by Trustee. (a) The Trustee shall transmit to
Holders such reports concerning the Trustee and its actions under this Indenture
as may be required pursuant to the Trust Indenture Act, at the times and in the

         transmission to Holders, be filed by the Trustee with each stock
         exchange or self regulatory organization of which the Trustee has

                  (a) in case the Company shall consolidate with or merge into
         another corporation or convey, transfer or lease its properties and
         assets substantially as an entirety to any Person, the corporation
         formed by such consolidation or into which the Company is merged or the

provisions. All the Debentures so issued shall in all respects have the same
legal rank and benefit under this Indenture as the Debentures theretofore or
thereafter issued in accordance with the terms of this Indenture as though all
of such Debentures had been issued at the date of the execution hereof.

         adverse to the Holders thereof;

provided that, so long as any Preferred Securities remain outstanding no
termination of this Indenture shall occur, and no waiver of any Event of Default
or compliance with any covenant under this Indenture shall be effective, without
the prior consent of the holders of at least a majority of the aggregate
liquidation preference of such

                                      77
<PAGE>
 
Preferred Securities then outstanding unless and until the principal (and
premium, if any) of the Debentures and all accrued and unpaid interest
(including any Additional Interest) thereon have been paid in full.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

         SECTION 9.3. Execution of Supplemental Indentures. In executing or
accepting the additional trusts created by any supplemental indenture permitted
by this Article or the modifications thereby of the trust created by this
Indenture, the Trustee shall be entitled to receive, and (subject to Section
6.1) shall be fully protected in relying upon, an Officers' Certificate and an
Opinion of Counsel stating that the execution of such supplemental indenture is
authorized or permitted by this Indenture, and that all conditions precedent
have been complied with. The Trustee may, but shall not be obligated to, enter
into any such supplemental indenture which affects the Trustee's own rights,
duties or immunities under this Indenture or otherwise.

         SECTION 9.4. Effect of Supplemental Indentures. Upon the execution of
any supplemental indenture under this Article, this Indenture shall be modified
in accordance therewith, and such supplemental indenture shall form a part of
this Indenture for all purposes, and every Holder of the Debentures theretofore
or thereafter authenticated and delivered hereunder shall be bound thereby.

         SECTION 9.5. Conformity with Trust Indentures Act. Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

         SECTION 9.6. Reference in Debentures to Supplemental Indentures.
Debentures authenticated and delivered after the execution of any supplemental
indenture pursuant to this Article may, and shall if required by the Trustee,
bear a notation in form approved by the Trustee as to any matter provided for in
such supplemental indenture. If the Company shall so determine, new Debentures
so modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any such supplemental indenture may be prepared and executed by
the Company and

                                      78
<PAGE>
 
authenticated and delivered by the Trustee in exchange for Outstanding
Debentures presented to the Trustee.

                                   ARTICLE 10

                                    COVENANTS

         SECTION 10.1. Payment of Principal, Premium and Interest. The Company
covenants and agrees for the benefit of the Debentures that it will duly and
punctually pay the principal of (and premium, if any) and interest on the
Debentures in accordance with the terms of the Debentures and this Indenture.

         SECTION 10.2. Maintenance of Office or Agency. The Company will
maintain in the United States, an office or agency where Debentures may be
presented or surrendered for payment and an office or agency where Debentures
may be surrendered for transfer or exchange and where notices and demands to or
upon the Company in respect of the Debentures and this Indenture may be served.
The Company initially appoints the Trustee, acting through its Corporate Trust
Office, as its agent for said purposes. The Company will give prompt written
notice to the Trustee of any change in the location of any such office or
agency. If at any time the Company shall fail to maintain such office or agency
or shall fail to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Debentures may be presented or surrendered for any
or all of such purposes, and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
United States for such purposes. The Company will give prompt written notice to
the Trustee of any such designation and any change in the location of any such
office or agency.

         SECTION 10.3. Money for Debenture Payments to Be Held in Trust. If the
Company shall at any time act as its own Paying Agent with respect to the
Debentures, it will, on or before each due date of the principal of (and
premium, if any) or interest on any of the Debentures,

                                      79
<PAGE>
 
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided, and will promptly notify the Trustee of its failure so to
act.

         Whenever the Company shall have one or more Paying Agents, it will, on
or before each due date of the principal of or interest on the Debentures,
deposit with a Paying Agent a sum sufficient to pay the principal (and premium,
if any) or interest so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal and premium (if any) or
interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its failure so to act.

         The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

                  (a) hold all sums held by it for the payment of the principal
         of (and premium, if any) or interest on Debentures in trust for the
         benefit of the Persons entitled thereto until such sums shall be paid
         to such Persons or otherwise disposed of as herein provided;

                  (b) give the Trustee notice of any default by the Company (or
         any other obligor upon the Debentures) in the making of any payment of
         principal (and premium, if any) or interest;

                  (c) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent; and

                  (d) comply with the provisions of the Trust Indenture Act
         applicable to it as a Paying Agent.

         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as

                                      80
<PAGE>
 
those upon which such sums were held by the Company or such Paying Agent, and,
upon such payment by the Company or any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Debenture and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall (unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be paid on Company Request, after all
payments owing the Trustee have been paid, to the Company, or (if then held by
the Company) shall (unless otherwise required by mandatory provision of
applicable escheat or abandoned or unclaimed property law) be discharged from
such trust; and the Holder of such Debenture shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease.

         SECTION 10.4. Payment of Taxes and Other Claims. The Company will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or any Subsidiary or upon the income, profits or
property of the Company or any Subsidiary, and (b) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a lien upon the
property of the Company or any Subsidiary; provided, however, that the Company
                                           --------  -------
shall not be required to pay or discharge or cause to be paid or discharged any
such tax, assessment, charge or claim whose amount, applicability or validity is
being contested in good faith by appropriate proceedings.

         SECTION 10.5. Statement as to Compliance. The Company shall deliver to
the Trustee, within 120 days after the end of each calendar year of the Company
ending after the date hereof an Officers' Certificate (signed by at least one of
the officers referred to in Section 314(a)(4) of the Trust Indenture Act)
covering the preceding calendar year, stating whether or not to the best
knowledge of the signers thereof the Company is in default in the performance,
observance or fulfillment of or

                                      81
<PAGE>
 
compliance with any of the terms, provisions, covenants and conditions of this
Indenture, and if the Company shall be in default, specifying all such defaults
and the nature and status thereof of which they may have knowledge. For the
purpose of this Section 10.5, compliance shall be determined without regard to
any grace period or requirement of notice provided pursuant to the terms of this
Indenture.

         SECTION 10.6. Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any covenant or condition set forth in this
Article 10, if before or after the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Debentures, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condi-tion except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company in
respect of any such covenant or condition shall remain in full force and effect.

         SECTION 10.7. Additional Sums. In the event that (a) the Property
Trustee is the Holder of all of the Outstanding Debentures, (b) a Tax Event in
respect of the Trust shall have occurred and be continuing and (c) the Company
shall not have (i) redeemed the Debentures pursuant to Section 11.7 or 11.8 or
(ii) terminated the Trust pursuant to Section 9.2(b) of the Trust Agreement, the
Company shall pay to the Trust (and its permitted successors or assigns under
the Trust Agreement) for so long as the Trust (or its permitted successor or
assignee) is the registered holder of the Debentures, such additional amounts as
may be necessary in order that the amount of distributions (including any
Additional Amounts (as defined in the Trust Agreement)) then due and payable by
the Trust on the Preferred Securities and Common Securities that at any time
remain outstanding in accord with the terms thereof shall not be reduced as a
result of any Additional Taxes (the "Additional Sums"). Whenever in this
Indenture or the Debentures there is a reference in any context to the payment
of principal of or interest on the Debentures, such mention shall be deemed to
include mention of the payments of the Additional Sums provided for in this
paragraph to the extent that, in such context, Additional Sums are, were or
would be payable in respect thereof pursuant to the provisions of this paragraph
and express mention of the payment of Additional Sums (if applicable) in any
provisions hereof shall not

                                      82
<PAGE>
 
be construed as excluding Additional Sums in those provisions hereof where such
express mention is not made, provided, however, that the extension of an
interest payment period pursuant to Section 3.11 or the Debentures shall not
extend the payment of any Additional Sums that may be due and payable during
such interest payment period.

         SECTION 10.8. Additional Covenants. The Company covenants and agrees
with each Holder of Debentures that so long as the Debentures are outstanding,
if (i) there shall have occurred any event of which the Company has actual
knowledge that (A) with the giving of notice or the lapse of time or both, would
constitute an Event of Default hereunder and (B) in respect of which the Company
shall not have taken reasonable steps to cure, (ii) the Company shall be in
default with respect to its payment of any obligations under the Guarantee or
(iii) the Company shall have given notice of its selection of an Extension
Period as provided herein and shall not have rescinded such notice, or such
period, or any extension thereof, shall be continuing, then the Company shall
not, and shall cause any Subsidiary not to, (x) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any shares of the Company's capital stock or (y) make any
payment of principal, interest or premium, if any, on or repay, repurchase or
redeem any debt securities (including guarantees of indebtedness for money
borrowed) of the Company that rank pari passu with or junior to the Debentures
(other than (1) any dividend, redemption, liquidation, interest, principal or
guarantee payment by the Company where the payment is made by way of securities
(including capital stock) that rank pari passu with or junior to the securities
on which such dividend, redemption, interest, principal or guarantee payment is
being made, (2) redemptions or purchases of any rights pursuant to the Company's
Shareholders Rights Plan, or any successor to such Shareholders Rights Plan, and
the declaration of a dividend of such rights or the issuance of preferred stock
under such plans in the future, (3) payments under the Guarantee, (4) purchases
of Common Stock related to the issuance of Common Stock under any of the
Company's benefit plans for its directors, officers or employees, (5) as a
result of a reclassification of the Company's capital stock or the exchange or
conversion of one series or class of the Company's capital stock for another
series or class of the Company's capital stock and (6) the purchase of
fractional interests in shares of the Company's capital stock pursuant to the
conversion or

                                      83
<PAGE>
 
exchange provisions of such capital stock or the security being converted or
exchanged).

         The Company also covenants with each Holder of the Debentures (i) that
for so long as Preferred Securities are outstanding not to convert the
Debentures except pursuant to a notice of conversion delivered to the Conversion
Agent by a holder of Preferred Securities and (ii) to maintain directly or
indirectly 100% ownership of the Common Securities of the Trust; provided,
however, that any permitted successor of the Company hereunder may succeed to
the Company's ownership of such Common Securities, (iii) not to voluntarily
terminate, wind-up or liquidate the Trust, except (a) in connection with a
distribution of the Debentures to the holders of Preferred Securities in
liquidation of the Trust or (b) in connection with certain mergers,
consolidations or amalgamations permitted by the Trust Agreement and (iv) to use
its reasonable efforts, consistent with the terms and provisions of the Trust
Agreement to cause the Trust to remain a business trust and not to be classified
as an association taxable as a corporation for United States Federal income tax
purposes.

         SECTION 10.9. Registration Rights. The holders of the Preferred
Securities, the Holders, the holders of the Guarantee and the shares of Common
Stock of the Company issuable upon conversion of the Securities are entitled to
the benefits of a Registration Rights Agreement, dated as of December 2, 1996,
among the Company and the Purchasers (the "Registration Rights Agreement").

         SECTION 10.10. Payment of Expenses of the Trust. In connection with the
offering, sale and issuance of the Debentures to the Property Trustee and in
connection with the sale of the Preferred Securities by the Trust, the Company
shall:

                  (a) pay for all costs, fees and expenses relating to the
offering, sale and issuance of the Securities (as defined in the Purchase
Agreement), including commissions, discounts and expenses payable pursuant to
the Purchase Agreement and compensation of the Trustee under the Indenture in
accordance with the provisions of Section 6.7 of the Indenture;

                  (b) be responsible for and pay for all debts and obligations
(other than with respect to the Preferred Securities) of the Trust, pay for all
costs and expenses of the Trust (including, but not limited to, costs and

                                      84
<PAGE>
 
expenses relating to the organization of the Trust, the offering, sale and
issuance of the Preferred Securities (including commissions, discounts and
expenses in connection therewith), the fees and expenses of the Property Trustee
and the Delaware Trustee, the costs and expenses relating to the operation of
the Trust, including without limitation, costs and expenses of accountants,
attorneys, statistical or bookkeeping services, expenses for printing and
engraving and computing or accounting equipment, paying agent(s), registrar(s),
transfer agent(s), duplicating, travel and telephone and other
telecommunications expenses and costs and expenses incurred in connection with
the acquisition, financing, and disposition of Trust assets); and

                  (c) pay any and all taxes (other than United States

                                   ARTICLE 11

                      REDEMPTION OR EXCHANGE OF DEBENTURES

         SECTION 11.1. Election to Redeem; Notice to Trustee. The election of
the Company to redeem any Debentures shall be evidenced by or pursuant to a
Board Resolution. In case of any redemption at the election of the Company, the
Company shall, not less than 45 days prior to the date fixed for redemption
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee in writing of such date and of the principal amount of Debentures to be
redeemed.

         SECTION 11.2. Selection of Debentures to Be Redeemed. If less than all
the Debentures are to be redeemed, the particular Debentures to be redeemed
shall be selected not more than 45 days prior to the Redemption Date by the
Trustee from the Outstanding Debentures not previously called for redemption, by
lot or by such other method as the Trustee shall deem fair and appropriate and
which may provide for the selection for redemption of a portion of the principal
amount of the Debentures Outstanding, provided that the unredeemed portion of
the principal amount of the Debentures be in an authorized denomination (which
shall not be less than the minimum authorized denomination) for the Debentures.

                                      85
<PAGE>
 
         The Trustee shall promptly notify the Company in writing of the
Debentures selected for partial redemption and the principal amount thereof to
be redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Debentures shall relate,
in the case of any Debenture redeemed or to be redeemed only in part, to the
portion of the principal amount of such Debenture which has been or is to be
redeemed. If the Company shall so direct, Debentures registered in the name of
the Company, any Affiliate or any Subsidiary thereof shall not be included in
the Debentures selected for redemption.

         SECTION 11.3. Notice of Redemption. Notice of redemption shall be given
by first-class mail, postage prepaid, mailed not later than the thirtieth day,
and not earlier than the sixtieth day, prior to the date fixed for redemption,
to each Holder of Debentures to be redeemed, at the address of such Holder as it
appears in the Securities Register.

         With respect to Debentures to be redeemed, each notice of redemption
shall state:

                  (a)  the Redemption Date;

                  (b) the redemption price at which the Debentures are to be
         redeemed (the "Redemption Price");

                  (c) if less than all Outstanding Debentures are to be
         redeemed, the identification (and, in the case of partial redemption,
         the respective principal amounts) of the particular Debentures to be
         redeemed (including, if relevant, the CUSIP or ISIN number);

                  (d) that on the Redemption Date the Redemption Price will
         become due and payable upon each such Debenture or portion thereof, and
         that upon deposit with the Paying Agent interest thereon, if any, shall
         cease to accrue on and after the Redemption Date;

                  (e) the place or places where the Debentures are to be
         surrendered for payment of the redemption price at which the Debentures
         are to be redeemed; and

                  (f) that a Holder of Debentures who desires to convert
         Debentures called for redemption must satisfy the requirements for
         conversion contained in the

                                      86
<PAGE>
 
         Debentures, the then existing conversion price or rate, and the date
         and time when the option to convert shall expire.

         Notice of redemption of Debentures to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.
The notice if mailed in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not the Holder receives such
notice. In any case, a failure to give such notice by mail or any defect in the
notice to the Holder of any Debenture designated for redemption as a whole or in
part shall not affect the validity of the proceedings for the redemption of any
other Debenture.

         SECTION 11.4. Deposit of Redemption Price. Prior to 12:00 noon, New
York City time, on the Redemption Date specified in the notice of redemption
given as provided in Section 11.3, the Company will deposit with the Trustee or
with one or more Paying Agents (or, if the Company is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 4.2) an amount of
money sufficient to redeem on the Redemption Date all the Debentures so called
for redemption at the applicable Redemption Price.

         If any Debenture called for redemption has been converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held in
trust for the redemption of such Debenture shall (subject to any right of the
Holder of such Debenture or any Predecessor Debenture to receive interest as
provided in the last paragraph of Section 3.7) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.

         SECTION 11.5. Debentures Payable on Redemption Date. If notice of
redemption has been given as provided in Section 11.3, the Debentures so to be
redeemed shall, on the Redemption Date, become due and payable at the Redemption
Price therein specified, including any accrued interest (and any Additional
Interest) thereon, and from and after such date (unless the Company shall
default in the payment of the Redemption Price or any accrued interest on
(including any Additional Interest)) such Debentures shall cease to bear
interest. Upon surrender of any such Debenture for redemption in accordance with
said notice, such Debenture shall be paid by the Company at

                                      87
<PAGE>
 
the Redemption Price, including any accrued interest (and any Additional
Interest) to the Redemption Date, provided, however, that installments of
                                  --------  -------
interest on Debentures whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Debentures, or one of more
Predecessor Debentures, registered as such at the close of business on the
relevant Regular Record Dates or Special Record Dates, as the case may be,
according to their terms and the provisions of Section 3.7.

         If any Debenture called for redemption shall not be so paid upon
surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in
the Debenture.

         SECTION 11.6. Debentures Redeemed in Part. In the event of any
redemption in part, the Company shall not be required to (i) issue, register the
transfer of or exchange any Debenture during a period beginning at 9:00 a.m.
(New York City time) 15 Business Days before any selection for redemption of
Debentures and ending at 5:00 p.m. (New York City time) on the earliest date in
which the relevant notice of redemption is deemed to have been given to all
holders of Debentures to be so redeemed and (ii) register the transfer of or
exchange any Debentures so selected for redemption, in whole or in part, except
for the unredeemed portion of any Debentures being redeemed in part.

         Any Debenture which is to be redeemed only in part shall be surrendered
at the place of payment therefor (with, if the Company or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company and the Trustee duly executed by, the Holder thereof
or his attorney duly authorized in writing), and the Company shall execute, and
the Trustee shall authenticate and make available for delivery to the Holder of
such Debenture without service charge, a new Debenture or Debentures, of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Debenture so surrendered. Each Debenture shall be subject to partial
redemption only in the amount of $50 or integral multiples thereof.

                                      88
<PAGE>
 
         The Debentures are not entitled to the benefit of any Sinking or like
fund.

         SECTION 11.7. Mandatory Redemption. Upon (i) repayment at maturity or
(ii) as a result of acceleration upon the occurrence of an Event of Default, the
Company shall redeem all the Outstanding Debentures at a redemption price equal
to 100% of the principal amount of such Debentures plus any accrued and unpaid
interest, including any Additional Interest, to the date fixed for redemption.

         SECTION 11.8. Optional Redemption. Except as set forth below, on and
after December 2, 1999 and subject to the next succeeding sentence, the Company
shall have the right, at any time and from time to time, to redeem the
Debentures, in whole or in part, upon notice given as set forth in Section 11.3
during the twelve-month periods beginning on December 2 in each of the following
years at the indicated Redemption Price (expressed as a percentage of the
principal amount of the Debentures being redeemed), together with any accrued
but unpaid interest on the portion being redeemed:

</TABLE> 

         The principal amount of the Debentures so redeemed may not, however,
exceed the amount of the proceeds derived, directly or indirectly, by the
Company or its Subsidiaries from the issuance and sale of Common Stock within
two years preceding the date fixed for redemption. The Company may not redeem
the Debentures in part unless all accrued and unpaid interest has been paid in
full on all outstanding Debentures for all quarterly interest periods
terminating on or prior to the giving of notice of the Redemption Date.

         If at any time following the Conversion Expiration Date, less than 5%
of the original aggregate principal amount of the Debentures remains
Outstanding, such Debentures shall be redeemable at the option of the Company,
in whole but not in part, at a Redemption Price equal to

                                      89
<PAGE>
 
the principal amount thereof, plus any accrued and unpaid interest.

          Upon the occurrence of a Tax Event, the Company 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 upon the later of (i) 90 days following the
occurrence of such Tax Event or (ii) December 2, 1999, at a Redemption Price
equal to the principal amount of such Debentures plus any accrued and unpaid
interest, including Additional Interest, to the date fixed for such redemption.

         SECTION 11.9. Exchange of Trust Securities for Debentures. (a) At any
time, the Company shall have the right to terminate the Trust and cause the
Debentures to be distributed to the holders of the Preferred Securities in
liquidation of the Trust after satisfaction of liabilities to creditors of the
Trust as provided by applicable law.

                  (b) If a Special Event in respect of the Trust shall occur,
the Company shall give the Property Trustee notice of the same. If a Special
Event in respect of the Trust shall occur and be continuing, the Trust Agreement
requires the Property Trustee to direct the Conversion Agent (as defined in the
Trust Agreement) to exchange all outstanding Trust Securities for the Debentures
having a principal amount equal to the aggregate liquidation amount of the Trust
Securities to be exchanged with accrued interest in an amount equal to any
unpaid distributions (including any Additional Amounts) on the Trust Securities
provided that, in the case of a Tax Event, the Company shall have the right to
- --------
direct the Property Trustee that less than all, or none of the Trust Securities
be so exchanged (i) if and for so long as the Company shall have elected to pay
any Additional Sums such that the net amounts received by holders of the Trust
Securities not so exchanged in respect of distributions are not reduced as a
result of such Tax Event, and shall not have revoked any such election or failed
to make such payments or (ii) if the Company shall instead elect to redeem the
Debentures, in whole or in part, in the manner set forth in Section 11.8.

                           SUBORDINATION OF DEBENTURES

         SECTION 12.1. Debentures Subordinate to Senior Debt. The Company
covenants and agrees, and each Holder of a Debenture, by its acceptance thereof,
likewise covenants and agrees, that, to the extent and in the manner hereinafter
set forth in this Article, the payment of the principal of (and premium, if any)
and interest (including any Additional Interest) on each and all of the
Debentures are hereby expressly made subordinate and subject in right of payment
to the prior payment in full of all amounts then due and payable in respect of
all Senior Debt (whether outstanding on the date hereof or hereafter created,
incurred, assumed or guaranteed), and that the subordination is for the benefit
of the holders of Senior Debt.

         SECTION 12.2. Payment Over of Proceeds Upon Dissolution, Etc. In case
of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company (each such event, if any, herein sometimes
referred to as a "Proceeding"), then the holders of Senior Debt shall be
entitled to receive payment in full of principal of (and premium, if any) and
interest (including interest after the commencement of any such proceeding at
the rate specified in the applicable Senior Debt), if any, on such Senior Debt,
or provision shall be made for such payment in cash or cash equivalents or
otherwise in a manner satisfactory to the holders of Senior Debt, before the
Holders of the Debentures are entitled to receive or retain any payment or
distribution of any kind or character, whether in cash, property or Debentures
(including any payment or distribution which may be payable or deliverable by
reason of the payment of any other Debt of the Company (including the
Debentures) subordinated to the payment of the Debentures, but not including any
payments that are made from funds on deposit pursuant to Section 4.1(a)(ii)(B)
or funds on deposit for the redemption of Debentures for which notice of
Redemption has been given and the applicable Redemption Date has passed, such
payment or distribution being hereinafter referred to as a "Junior Subordinated
Payment"), on account of principal of (or premium, if any) or interest
(including any Additional Interest) on the Debentures or on account of the
purchase or other acquisition of Debentures by the Company or any Subsidiary and
to that end the holders of

                                      91
<PAGE>
 
Senior Debt shall be entitled to receive, for application to the payment thereof
any payment or distribution of any kind of character, whether in cash, property
or Debentures, including any Junior Subordinated Payment, which may be payable
or deliverable in respect of the Debentures in any such Proceeding.

         In the event that, notwithstanding the foregoing provisions of this
Section, the Trustee or the Holder of any Debenture shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or Debentures, including any Junior Subordinated
Payment, before all Senior Debt is paid in full or payment thereof is provided
for in cash or cash equivalents or otherwise in a manner satisfactory to the
holders of Senior Debt, and if such fact shall, at or prior to the time of such
payment or distribution, have been made known to the Trustee or, as the case may
be, such Holder, then and in such event such payment or distribution shall be
paid over or delivered forthwith to the trustee in bankruptcy, receiver,
liquidating trustee, custodian, assignee, agent or other Person making payment
or distribution of assets of the Company for application to the payment of all
Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in
full, after giving effect to any concurrent payment or distribution to or for
the holders of Senior Debt.

         For the purposes of this Article only, the words "any payment or
distribution of any kind or character, whether in cash, property or securities"
shall not be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment which securities are subordinated in
right of payment to all then outstanding Senior Debt to substantially the same
extent as the Debentures are so subordinated as provided in this Article. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the sale of
all or substantially all of its properties and assets as an entirety to another
Person or the liquidation or dissolution of the Company following the sale of
all or substantially all of its properties and assets as an entirety to another
Person upon the terms and conditions set forth in Article 8 shall not be deemed
a Proceeding for the purposes of this Section if the Person formed by such
consolidation or into which the Company is merged or the Person which acquires
by sale such properties and assets

                                      92
<PAGE>
 
as an entirety, as the case may be, shall, as a part of such consolidation,
merger, or sale comply with the conditions set forth in Article Eight.

         SECTION 12.3. Prior Payment to Senior Debt upon Acceleration of
Debentures. In the event that the Debentures are declared due and payable before
their Maturity, then and in such event the holders of the Senior Debt
outstanding at the time the Debentures so become due and payable shall be
entitled to receive payment in full of all amounts due on or in respect of such
Senior Debt (including any amounts due upon acceleration), or provision shall be
made for such payment in cash or cash equivalents or otherwise in a manner
satisfactory to the holders of Senior Debt, before the Holders of the Debentures
are entitled to receive any payment or distribution of any kind or character,
whether in cash, properties or securities (including any Junior Subordinated
Payment) by the Company on account of the principal of (or premium, if any) or
interest (including any Additional Interest) on the Debentures or on account of
the purchase or other acquisition of Debentures by the Company or any
Subsidiary.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of the Debentures prohibited by
the foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known, as set forth in Section 12.10,
to the Trustee or, as the case may be, such Holder, then and in such event such
payment shall be paid over and delivered forthwith to the Company.

         The provisions of this Section shall not apply to any payment with
respect to which Section 12.2 would be applicable.

         SECTION 12.4. No Payment When Senior Debt in Default. (a) In the event
and during the continuation of any default in the payment of principal of (or
premium, if any) or interest on any Senior Debt, or in the event that any event
of default with respect to any Senior Debt shall have occurred and be continuing
and shall have resulted in such Senior Debt becoming or being declared due and
payable prior to the date on which it would otherwise have become due and
payable, unless and until such event of default shall have been cured or waived
or shall have ceased to exist and such acceleration shall have been rescinded or
annulled, or (b) in the event any

                                      93
<PAGE>
 
judicial proceeding shall be pending with respect to any such default in payment
or such event or default, then no payment or distribution of any kind or
character, whether in cash, properties or Debentures (including any Junior
Subordinated Payment) shall be made by the Company on account of principal of
(or premium, if any) or interest (including any Additional Interest), if any, on
the Debentures or on account of the purchase or other acquisition of Debentures
by the Company or any Subsidiary other than payments made from funds on deposit
pursuant to Section 4.1(a)(ii)(B) or from funds on deposit for the redemption of
Debentures for which notice of redemption has been given and the Redemption Date
has passed.

         In the event that, notwithstanding the foregoing, the Company shall
make any payment to the Trustee or the Holder of the Debentures prohibited by
the foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known as set forth in Section 12.10, to
the Trustee or, as the case may be, such Holder, then and in such event such
payment shall be paid over and delivered forthwith to the Company.

         The provisions of this Section shall not apply to any payment with
respect to which Section 12.2 would be applicable.

         SECTION 12.5. Payment Permitted If No Default. Nothing contained in
this Article or elsewhere in this Indenture or in any of the Debentures shall
prevent (a) the Company, at any time except during the pendency of any
Proceeding referred to in Section 12.2 or under the conditions described in
Sections 12.3 and 12.4, from making payments at any time of principal of (and
premium, if any) or interest on the Debentures, or (b) the application by the
Trustee of any money deposited with it hereunder to the payment of or on account
of the principal of (and premium, if any) or interest (including any Additional
Interest) on the Debentures or the retention of such payment by the Holders, if,
at the time of such application by the Trustee, the Trustee did not have actual
knowledge that such payment would have been prohibited by the provisions of this
Article.

         SECTION 12.6. Subrogation to Rights of Holders of Senior Debt. Subject
to the payment in full of all Senior Debt, or the provision for such payment in
cash or cash equivalents or otherwise in a manner satisfactory to the holders of
Senior Debt, the Holders of the Debentures

                                      94
<PAGE>
 
shall be subrogated to the extent of the payments or distributions made to the
holders of such Senior Debt pursuant to the provisions of this Article (equally
and ratably with the holders of all indebtedness of the Company which by its
express terms is subordinated to Senior Debt of the Company to substantially the
same extent as the Debentures are subordinated to the Senior Debt and is
entitled to like rights of subrogation by reason of any payments or
distributions made to holders of such Senior Debt) to the rights of the holders
of such Senior Debt to receive payments and distributions of cash, property and
securities applicable to the Senior Debt until the principal of (and premium, if
any) and interest on the Debentures shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior Debt of
any cash, property or securities to which the Holders of the Debentures or the
Trustee would be entitled except for the provisions of this Article, and no
payments pursuant to the provisions of this Article to the holders of Senior
Debt by Holders of the Debentures or the Trustee, shall, as among the Company,
its creditors other than holders of Senior Debt, and the Holders of the
Debentures, be deemed to be a payment or distribution by the Company to or on
account of the Senior Debt.

         SECTION 12.7. Provisions Solely to Define Relative Rights. The
provisions of this Article are and are intended solely for the purpose of
defining the relative rights of the Holders of the Debentures on the one hand
and the holders of Senior Debt on the other hand. Nothing contained in this
Article or elsewhere in this Indenture or in the Debentures is intended to or
shall (a) impair, as between the Company and the Holders of the Debentures, the
obligations of the Company, which are absolute and unconditional, to pay to the
Holders of the Debentures the principal of (and premium, if any) and interest
(including any Additional Interest) on the Debentures as and when the same shall
become due and payable in accordance with their terms, or (b) affect the
relative rights against the Company of the Holders of the Debentures and
creditors of the Company other than their rights in relation to the holders of
Senior Debt, or (c) prevent the Trustee or the Holder of any Debenture from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture including, without limitation, filing and voting claims in any
Proceeding, subject to the rights, if any, under this Article of the holders of
Senior Debt to receive cash, property and

                                      95
<PAGE>
 
securities otherwise payable or deliverable to the Trustee or such Holder.

         SECTION 12.8.  Trustee to Effectuate Subordination. Each Holder of a
Debenture by his or her acceptance thereof authorizes and directs the Trustee on
his or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination provided in this Article and
appoints the Trustee his or her attorney-in-fact for any and all such purposes.

         SECTION 12.9.  No Waiver of Subordination Provisions. No right of any
present or future holder of any Senior Debt to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof that any such holder may have or be otherwise charged with.

         SECTION 12.10. Notice to Trustee. The Company shall give prompt written
notice to the Trustee of any fact known to the Company which would prohibit the
making of any payment to or by the Trustee in respect of the Debentures.
Notwithstanding the provisions of this Article or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts which would prohibit the making of any payment to or by the Trustee in
respect of the Debentures, unless and until the Trustee shall have received
written notice thereof from the Company or a person representing itself as a
holder of Senior Debt or from any trustee, agent or representative therefor
(whether or not the facts contained in such notice are true).

         SECTION 12.11. Reliance on Judicial Order or Certificate of Liquidating
Agent. Upon any payment or distribution of assets of the Company referred to in
this Article, the Trustee, subject to the provisions of Article 6, and the
Holders of the Debentures shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which a Proceeding is pending,
or a certificate of the trustee in bankruptcy, receiver, liquidating trustee,
custodian, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the Holders of
Debentures, for the purpose of ascertaining the Persons entitled to participate
in such

                                      96
<PAGE>
 
payment or distribution, the holders of the Senior Debt and other indebtedness
of the Company, the amount thereof or payable thereon, the amount or amounts
paid or distributed thereon and all other facts pertinent thereto or to this
Article.

         SECTION 12.12. Trustee Not Fiduciary for Holders of Senior Debt. With
respect to the holders of the Senior Debt of the Company, the Trustee undertakes
to perform or observe only such of its obligations and covenants as are set
forth in this Article 12, and no implied covenants or obligations with respect
to the holders of such Senior Debt shall be read into this Indenture against IBJ
Schroder and/or the Trustee. IBJ Schroder and/or the Trustee shall not be deemed
to owe any fiduciary duty to the holders of such Senior Debt and, subject to the
provisions of Section 6.3, neither the Trustee (nor IBJ Schroder) shall be
liable to the holder of any Senior Debt if it shall pay over or deliver to
Holders, the Company, or any other person, money or assets to which any holder
of such Senior Debt shall be entitled to by virtue of this Article 12 or
otherwise.

         SECTION 12.13. Rights of Trustee as Holder of Senior Debt; Preservation
of Trustee's Rights. The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article with respect to any Senior Debt which
may at any time be held by it, to the same extent as any other holder of Senior
Debt, and, subject to the requirements of the Trust Indenture Act, nothing in
this Indenture shall deprive the Trustee of any of its rights as such holder.

         SECTION 12.14. Article Applicable to Paying Agents. In case at any time
any Paying Agent other than the Trustee shall have been appointed by the Company
and be then acting hereunder, the term "Trustee" as used in this Article shall
in such case (unless the context otherwise requires) be construed as extending
to and including such Paying Agent within its meaning as fully for all intent
and purposes as if such Paying Agent were named in this Article in addition to
or in place of the Trustee.

         SECTION 12.15. Certain Conversions or Exchanges Deemed Payment. For the
purpose of this Article only, (a) the issuance and delivery of junior securities
upon conversion or exchange of Debentures shall not be deemed to constitute a
payment or distribution on account of the principal of (or premium, if any) or
interest (including any Additional Interest) on the Debentures or on account

                                      97
<PAGE>
 
of the purchase or other acquisition of Debentures, and (b) the payment,
issuance or delivery of cash (including any payments for fractional shares),
property or securities (other than junior securities) upon conversion or
exchange of a Debenture shall be deemed to constitute payment on account of the
principal of such security. For the purpose of this Section, the term "junior
securities" means (i) shares of any stock of any class of the Company and (ii)
securities of the Company which are subordinated in right of payment to all
Senior Debt which may be outstanding at the time of issuance or delivery of such
securities to substantially the same extent as, or to a greater extent than, the
Debentures are so subordinated as provided in this Article.


                                  ARTICLE 13

                           CONVERSION OF DEBENTURES

         SECTION 13.1. Conversion Rights. Subject to and upon compliance with
the provisions of this Article, the Debentures are convertible, at the option of
the Holder, at any time prior to the Conversion Expiration Date, into fully paid
and nonassessable shares of Common Stock of the Company at an initial conversion
rate of 2.6876 shares of Common Stock for each $50 in aggregate principal amount
of Debentures (equal to a conversion price of $18.604 per share of Common
Stock), subject to adjustment as described in this Article 13 (as adjusted the
"Conversion Price"). A Holder of Debentures may convert any portion of the
principal amount of the Debentures into that number of fully paid and
nonassessable shares of Common Stock (calculated as to each conversion to the
nearest 1/100th of a share) obtained by dividing the principal amount of the
Debentures to be converted by the Conversion Price. In case a Debenture or
portion thereof is called for redemption, such conversion right in respect of
the Debenture or portion so called shall expire at the close of business on the
Business Day immediately preceding the corresponding Redemption Date, unless the
Company defaults in making the payment due upon redemption.

         SECTION 13.2. Conversion Procedures.  (a)  In order to convert all or a
portion of the Debentures, the Holder thereof shall deliver to the Property
Trustee, as conversion agent or to such other agent appointed for such purposes
(the "Conversion Agent") an irrevocable Notice of Conversion setting forth the
principal amount of

                                      98
<PAGE>
 
Debentures to be converted, together with the name or names, if other than the
Holder, in which the shares of Common Stock should be issued upon conversion
and, if such Debentures are definitive Debentures, surrender to the Conversion
Agent the Debentures to be converted, duly endorsed or assigned to the Company
or in blank. In addition, a holder of Preferred Securities may exercise its
right under the Trust Agreement to convert such Preferred Securities into Common
Stock by delivering to the Conversion Agent an irrevocable Notice of Conversion
setting forth the information called for by the preceding sentence and directing
the Conversion Agent (i) to exchange such Preferred Security for a portion of
the Debentures held by the Trust (at an exchange rate of $50 principal amount of
Debentures for each Preferred Security) and (ii) to immediately convert such
Debentures, on behalf of such holder, into Common Stock of the Company pursuant
to this Article 13 and, if such Preferred Securities are in definitive form,
surrendering such Preferred Securities, duly endorsed or assigned to the Company
or in blank. So long as any Preferred Securities are outstanding, the Trust
shall not convert any Debentures except pursuant to a Notice of Conversion
delivered to the Conversion Agent by a holder of Preferred Securities.

         If a Notice of Conversion is delivered on or after the Regular Record
Date and prior to the subsequent Interest Payment Date, the Holder of record on
the Regular Record Date will be entitled to receive the interest paid on the
subsequent Interest Payment Date on the portion of Debentures to be converted
notwithstanding the conversion thereof prior to such Interest Payment Date.
Except as otherwise provided in the immediately preceding sentence, in the case
of any Debenture which is converted, interest whose Stated Maturity is on or
after the date of conversion of such Debenture shall not be payable, and the
Company shall not make nor be required to make any other payment, adjustment or
allowance with respect to accrued but unpaid interest on the Debentures being
converted, which shall be deemed to be paid in full. Each conversion shall be
deemed to have been effected immediately prior to the close of business on the
day on which the Notice of Conversion was received (the "Conversion Date") by
the Conversion Agent from the Holder or from a holder of the Preferred
Securities effecting a conversion thereof pursuant to its conversion rights
under the Trust Agreement, as the case may be. The Person or Persons entitled to
receive the Common Stock issuable upon such conversion shall be treated for

                                      99
<PAGE>
 
all purposes as the record holder or holders of such Common Stock as of the
Conversion Date and such Person or Persons will cease to be a record Holder or
record Holders of the Debentures on that date. As promptly as practicable on or
after the Conversion Date, the Company shall issue and deliver at the office of
the Conversion Agent, unless otherwise directed by the Holder or holder in the
Notice of Conversion, a certificate or certificates for the number of full
shares of Common Stock issuable upon such conversion, together with the cash
payment, if any, in lieu of any fraction of any share to the Person or Persons
entitled to receive the same. The Conversion Agent shall deliver such
certificate or certificates to such Person or Persons.

                  (b)  The Company's delivery upon conversion of the fixed
number of shares of Common Stock into which the Debentures are convertible
(together with the cash payment, if any, in lieu of fractional shares) shall be
deemed to satisfy the Company's obligation to pay the principal amount at
Maturity of the portion of Debentures so converted and any unpaid interest
(including Additional Interest and Liquidated Damages) accrued on such
Debentures at the time of such conversion.

                  (c)  No fractional shares of Common Stock will be issued as a
result of conversion, but in lieu thereof, the Company shall pay to the
Conversion Agent a cash adjustment in an amount equal to the same fraction of
the Current Market Price with respect to such fractional interest on the date on
which the Debentures or Preferred Securities, as the case may be, were duly
surrendered to the Conversion Agent for conversion, and the Conversion Agent in
turn will make such payment, if any, to the Holder of the Securities or the
holder of the Preferred Securities so converted.

                  (d)  In the event of the conversion of any Debenture in part
only, a new Debenture or Debentures for the unconverted portion thereof will be
issued in the name of the Holder thereof upon the cancellation of the Debenture
converted in part in accordance with Section 3.5.

                  (e)  In effecting the conversion transactions described in
this Section, the Conversion Agent is acting as agent of the holders of
Preferred Securities (in the exchange of Preferred Securities for Debentures)
and as agent of the Holders of Debentures (in the conversion of Debentures into
Common Stock), as the case may be, di-

                                      100
<PAGE>
 
recting it to effect such conversion transactions. The Conversion Agent is
hereby authorized (i) to exchange Debentures held by the Trust from time to time
for Preferred Securities in connection with the conversion of such Preferred
Securities in accordance with this Article 13 and (ii) to convert all or a
portion of the Debentures into Common Stock and thereupon to deliver such shares
of Common Stock in accordance with the provisions of this Article 13 and to
deliver to the Trust a new Debenture or Debentures for any resulting unconverted
principal amount.

                  (f)  All shares of Common Stock delivered upon any conversion
of Restricted Securities shall bear a Restrictive Securities Legend
substantially in the form of the legend required to be set forth on such
Debentures and shall be subject to the restrictions on transfer provided in such
legend and in Section 3.5 hereof. Neither the Trustee nor the Conversion Agent
shall have any responsibility for the inclusion or content of any such
Restrictive Securities Legend on such Common Stock; provided, however, that the
                                                    --------  -------
Trustee or the Conversion Agent shall have provided to the Company or to the
Company's transfer agent for such Common Stock, prior to or concurrently with a
request to the Company to deliver to such Conversion Agent certificates for such
Common Stock, written notice that the Debentures delivered for conversion are
Restricted Securities.

                  (g)  The Company shall at all times reserve and keep available
out of its authorized and unissued Common Stock, solely for issuance upon the
conversion of the Debentures, such number of shares of Common Stock as shall
from time to time be issuable upon the conversion of all the Debentures then
outstanding. Notwithstanding the foregoing, the Company shall be entitled to
deliver upon conversion of Debentures shares of Common Stock reacquired and held
in the treasury of the Company (in lieu of the issuance of authorized and
unissued shares of Common Stock) so long as any such treasury shares are free
and clear of all liens, charges, security interests or encumbrances. Whenever
the Company issues shares of Common Stock upon conversion of Debentures and the
Company has in effect at such time a share purchase rights agreement under which
holders of Common Stock are issued rights ("Rights") entitling the holders under
certain circumstances to purchase an additional share or shares of stock, the
Company will issue, together with each such share of Common Stock, such number
of Rights (which number may be a fraction) as shall at that time be issu-

                                      101
<PAGE>
 
able with a share of Common Stock pursuant to such share purchase rights
agreement (currently, half of a Right). Any shares of Common Stock issued upon
conversion of the Debentures shall be duly authorized, validly issued and fully
paid and nonassessable. The Conversion Agent shall deliver the shares of Common
Stock received upon conversion of the Debentures to the converting Holder free
and clear of all liens, charges, security interests and encumbrances, except for
United States withholding taxes. The Company shall use its best efforts to
obtain and keep in force such governmental or regulatory permits or other
authorizations as may be required by law, and shall comply with all applicable
requirements as to registration or qualification of the Common Stock (and all
requirements to list the Common Stock issuable upon conversion of Debentures
that are at the time applicable), in order to enable the Company to lawfully
issue Common Stock upon conversion of the Debentures and to lawfully deliver the
Common Stock to each Holder upon conversion of the Debentures.

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

                  (i)  Nothing in this Article 13 shall limit the requirement of
the Company to withhold taxes pursuant to the terms of the Debentures or as set
forth in this Agreement or otherwise require the Trustee or the Company to pay
any amounts on account of such withholdings.

         SECTION 13.3. Expiration of Conversion Rights. (a) On and after
December 2, 1999, the Company may, at its option, cause the conversion rights of
Holders of Debentures to expire; provided, however, that the Company may
exercise this option only if for 20 trading days within any period of 30
consecutive trading days, including the last trading day of such period, the
Current Market Price of Common Stock exceeds 120% of the Conversion Price of the
Debentures, subject to adjustment as described in this Section.

                                      102
<PAGE>
 
                  (b)  In order to exercise its option to terminate the
conversion rights of the Debentures, the Company must issue a press release for
publication on the Dow Jones News Service announcing the Conversion Expiration
Date prior to the opening of business on the second trading day after any period
in which the condition in Section 13.3(a) has been met, but in no event prior to
December 2, 1999. The press release shall announce the Conversion Expiration
Date (which may not occur sooner than 30 nor more than 60 days after the Company
issues the press release announcing its intention to terminate the conversion
rights of the Debentures) and provide the current Conversion Price and Current
Market Price of Common Stock, in each case as of the close of business on the
trading day next preceding the date of the press release. Conversion rights will
terminate at the close of business on the Conversion Expiration Date.

                  (c)  In addition to issuing the press release referred to in
the preceding paragraph the Company or at the Company's request, the Property
Trustee, shall send notice of the expiration of conversion rights by first-class
mail to the Holders of the Debentures not more than four Business Days after the
Company issues the press release. Such mailed notice of the expiration of the
conversion rights of the Holders shall state: (i) the Conversion Expiration
Date; (ii) the Conversion Price of the Debentures and the Current Market Price
of the Common Stock, in each case as of the close of business on the Business
Day next preceding the date of the notice of expiration of the conversion rights
of the Holders; (iii) the place or places at which Debentures may be surrendered
prior to the Conversion Expiration Date for certificates representing shares of
Common Stock; and (iv) such other information or instructions as the Company
deems necessary or advisable to enable a Holder to exercise its conversion right
hereunder. No defect in the notice of expiration of the conversion rights of the
Holders or in the mailing thereof with respect to any Debentures shall affect
the validity of such notice with respect to any other Debenture. As of the close
of business on the Conversion Expiration Date, the Debenture shall no longer be
convertible into Common Stock. If the Company does not exercise its option to
terminate the conversion rights of the Holders of the Debentures, the Conversion
Expiration Date with respect to the Debentures will be the close of business two
Business Days preceding the date set for redemption of the Debentures upon the
mandatory redemption or Stated Maturity of the Debentures.

         SECTION 13.4. Conversion Price Adjustments. The conversion price shall
be subject to adjustment (without duplication) from time to time as follows:

                  (a)  In case the Company shall, while any of the Debentures
are outstanding, (i) pay a dividend or make a distribution with respect to its
Common Stock in shares of Common Stock, (ii) subdivide its outstanding shares of
Common Stock, (iii) combine its outstanding shares of Common Stock into a
smaller number of shares or (iv) issue by reclassification of its shares of
Common Stock any shares of capital stock of the Company, the conversion
privilege and the Conversion Price in effect immediately prior to such action
shall be adjusted so that the Holder of any Debentures thereafter surrendered
for conversion shall be entitled to receive the number of shares of capital
stock of the Company which he would have owned immediately following such action
had such Debentures been converted immediately prior thereto. An adjustment made
pursuant to this subsection (a) shall become effective immediately after the
record date in the case of a dividend or other distribution and shall become
effective immediately after the effective date in case of a subdivision,
combination or reclassification (or immediately after the record date if a
record date shall have been established for such event). If, as a result of an
adjustment made pursuant to this subsection (a), the Holder of any Debenture
thereafter surrendered for conversion shall become entitled to receive shares of
two or more classes or series of capital stock of the Company, the Board of
Directors (whose determination shall be conclusive and shall be described in a
Board Resolution filed with the Trustee) shall determine the allocation of the
adjusted Conversion Price between or among shares of such classes or series of
capital stock. In the event that such dividend, distribution, subdivision,
combination or issuance is not so paid or made, the Conversion Price shall again
be adjusted to be the Conversion Price which would then be in effect if such
record date had not been fixed.

                  (b)  In case the Company shall, while any of the Debentures
are Outstanding, issue rights or warrants to all holders of its Common Stock
entitling them (for a period expiring within 45 days after the record date
mentioned below) to subscribe for or purchase shares of Common Stock at a price
per share less than the Current Market Price per share of Common Stock on the
record date mentioned below, the Conversion Price for the Debentures shall be
adjusted so that the same shall equal the price

                                      104
<PAGE>
 
determined by multiplying the Conversion Price in effect immediately prior to
the date of issuance of such rights or warrants by a fraction of which the
numerator shall be the number of shares of Common Stock outstanding on the date
of issuance of such rights or warrants plus the number of shares which the
aggregate offering price of the total number of shares so offered for
subscription or purchase would purchase at such Current Market Price, and of
which the denominator shall be the number of shares of Common Stock outstanding
on the date of issuance of such rights or warrants plus the number of additional
shares of Common Stock offered for subscription or purchase. Such adjustment
shall become effective immediately after the record date for the determination
of stockholders entitled to receive such rights or warrants. For the purposes of
this subsection, the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company. The Company shall
not issue any rights or warrants in respect of shares of Common Stock held in
the treasury of the Company. In case any rights or warrants referred to in this
subsection in respect of which an adjustment shall have been made shall expire
unexercised within 45 days after the same shall have been distributed or issued
by the Company, the Conversion Price shall be readjusted at the time of such
expiration to the Conversion Price that would have been in effect if no
adjustment had been made on account of the distribution or issuance of such
expired rights or warrants.

                  (c)  Subject to the last sentence of this sub-paragraph, in
case the Company shall, by dividend or otherwise, distribute to all holders of
its Common Stock evidences of its indebtedness, shares of any class or series of
capital stock, cash or assets (including securities, but excluding any rights or
warrants referred to in subparagraph (b), any dividend or distribution paid
exclusively in cash and any dividend or distribution referred to in subparagraph
(a) of this Section 13.4), the Conversion Price shall be reduced so that the
same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the effectiveness of the Conversion Price reduction
contemplated by this sub-paragraph (c) by a fraction of which the numerator
shall be the Current Market Price per share of the Common Stock on the date
fixed for the payment of such distribution (the "Reference Date") less the fair
market value (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of
Directors), on the Reference

                                      105
<PAGE>
 
Date, of the portion of the evidences of indebtedness, shares of capital stock,
cash and assets so distributed applicable to one share of Common Stock and the
denominator shall be such current market price per share of the Common Stock,
such reduction to become effective immediately prior to the opening of business
on the day following the Reference Date. In the event that such dividend or
distribution is not so paid or made, the Conversion Price shall again be
adjusted to be the Conversion Price which would then be in effect if such
dividend or distribution had not occurred. For purposes of this subparagraph
(c), any dividend or distribution that includes shares of Common Stock or rights
or warrants to subscribe for or purchase shares of Common Stock shall be deemed
instead to be (i) a dividend or distribution of the evidences of indebtedness,
shares of capital stock, cash or assets other than such shares of Common Stock
or such rights or warrants (making any Conversion Price reduction required by
this subparagraph (c)) immediately followed by (ii) a dividend or distribution
of such shares of Common Stock or such rights or warrants (making any further
conversion price reduction required by subparagraph (a) or (b)), except (A) the
Reference Date of such dividend or distribution as defined in this subparagraph
shall be substituted as (x) "the record date in the case of a dividend or other
distribution," and (y) "the record date for the determination of stockholders
entitled to receive such rights or warrants" and (z) "the date fixed for such
determination" within the meaning of subparagraphs (a) and (b) and (B) any
shares of Common Stock included in such dividend or distribution shall not be
deemed outstanding for purposes of computing any adjustment of the conversion
price in subparagraph (a).

                  (d)  In case the Company shall pay or make a dividend or other
distribution on its Common Stock exclusively in cash (excluding all regular cash
dividends, if the annualized amount thereof per share of Common Stock does not
exceed 12.5% of the current market price per share of the Common Stock on the
trading day immediately preceding the date of declaration of such dividend), the
Conversion Price shall be reduced so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (d) by a fraction of which the numerator shall be the Current
Market Price per share of the Common Stock on the date fixed for the payment of
such distribution less the amount of cash so distributed (excluding that portion
of such distribution that does not exceed

                                      106
<PAGE>
 
12.5% of the Current Market Price per share, determined as provided above)
applicable to one share of Common Stock and the denominator shall be such
Current Market Price per share of the Common Stock, such reduction to become
effective immediately prior to the opening of business on the day following the
date fixed for the payment of such distribution; provided, however, that in the
                                                 --------  -------
event the portion of the cash so distributed applicable to one share of Common
Stock is equal to or greater than the Current Market Price per share of the
Common Stock on the record date mentioned above (excluding that portion of such
distribution that does not exceed 12.5% of the Current Market Price per share,
determined as provided above), in lieu of the foregoing adjustment, adequate
provision shall be made so that each Holder of shares of Debentures shall have
the right to receive upon conversion the amount of cash such Holder would have
received had such Holder converted each share of the Debentures immediately
prior to the record date for the distribution of the cash (less that portion of
such distribution that does not exceed 12.5% of the Current Market Price per
share, determined as provided above). In the event that such dividend or
distribution is not so paid or made, the Conversion Price shall again be
adjusted to be the conversion price which would then be in effect if such record
date had not been fixed.

                  (e)  In case a tender or exchange offer (other than an odd-lot
offer) made by the Company or any Subsidiary of the Company for all or any
portion of the Common Stock shall expire and such tender or exchange offer shall
involve the payment by the Company or such Subsidiary of consideration per share
of Common Stock having a fair market value (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and described in a
resolution of the Board of Directors) at the last time (the "Expiration Time")
tenders or exchanges may be made pursuant to such tender or exchange offer (as
it shall have been amended) that exceeds 110% of the Current Market Price per
share of the Common Stock on the trading day next succeeding the Expiration
Time, the Conversion Price shall be reduced so that the same shall equal the
price determined by multiplying the Conversion Price in effect immediately prior
to the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (e) by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding (including any tendered or exchanged shares)
at the Expiration Time (including the Purchased Shares) (as defined below)
multiplied by the Current

                                      107
<PAGE>
 
Market Price per share of the Common Stock on the Trading Day next succeeding
the Expiration Time and the denominator shall be the sum of (x) the fair market
value (determined as aforesaid) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the tender or exchange offer) of all shares validly tendered or exchanged and
not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the "Purchased Shares") (excluding that
portion of such consideration that does not exceed 110% of the Current Market
Price per share) and (y) the product of the number of shares of Common Stock
outstanding (less any Purchased Shares) at the Expiration Time and the Current
Market Price per share of the Common Stock on the trading day next succeeding
the Expiration Time, such reduction to become effective immediately prior to the
opening of business on the day following the Expiration Time. In the event that
such tender or exchange offer is not so made, the Conversion Price shall again
be adjusted to be the Conversion Price which would then be in effect if such
record date had not been fixed.

                  (f)  If the distribution date for the Rights of the Company
provided in the Shareholders Rights Plan, as presently constituted or under any
similar plan occurs prior to the Conversion Date, and a Holder of the Debentures
who converts such Debentures after such distribution date is not entitled to
receive the Rights that would otherwise be attached (but for the date of
conversion) to the shares of Common Stock received upon such conversion, then an
adjustment shall be made to the Conversion Price pursuant to clause (ii) of
Section 13.4(a) as if the Rights were being distributed to the common
stockholders of the Company immediately prior to such conversion. If such an
adjustment is made and the Rights are later redeemed, invalidated or terminated,
then a corresponding reversing adjustment shall be made to the Conversion Price,
on an equitable basis, to take account of such event.

                  (g)  The Company shall have the right to reduce from time to
time the Conversion Price by any amount selected by the Company for any period
of at least 30 days, provided, that Company shall give at least 15 days' notice
                     --------
of such reduction to the Trustee and the Property Trustee. The Company may, at
its option, make such reductions in the Conversion Price, in addition to those
set forth above in Section 13.4(a), as the Board of Directors deems advisable to
avoid or diminish any income

                                      108
<PAGE>
 
tax to holders of Common Stock resulting from any dividend or distribution of
stock (or rights to acquire stock) or from any event treated as such for income
tax purposes. No adjustment of the Conversion Price will be made upon the
issuance of any shares of Common Stock pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on securities of
the Company and the investment of additional optional amounts in shares of
Common Stock under any such plan, or the issuance of any shares of Common Stock
or options or rights to purchase such shares pursuant to any present or future
employee benefit plan or program of the Company or pursuant to any option,
warrant, right, or exercisable, exchangeable or convertible security which does
not constitute an issuance to all holders of Common Stock of rights or warrants
entitling holders of such rights or warrants to subscribe for or purchase Common
Stock at less than the Current Market Price. There shall also be no adjustment
of the Conversion Price in case of the issuance of any Common Stock (or
securities convertible into or exchangeable for Common Stock), except as
specifically described above.

                  (h)  If any action would require adjustment of the Conversion
Price pursuant to more than one of the provisions described above, only one
adjustment shall be made and such adjustment shall be the amount of adjustment
that has the highest absolute value to the Holder of the Debentures.

         SECTION 13.5. Fundamental Change. (a) In the event that the Company is
a party to any transaction (including, without limitation, a merger other than a
merger that does not result in a reclassification, conversion, exchange or
cancellation of Common Stock), consolidation, sale of all or substantially all
of the assets of the Company, recapitalization or reclassification of Common
Stock (other than a change in par value, or from par value to no par value, or
from no par value to par value or as a result of a subdivision or combination
of Common Stock) or any compulsory share exchange (each of the foregoing being
referred to as a "Transaction"), in each case, as a result of which shares of
Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (and subject to funds being legally
available for such purpose under applicable law and the time of such
conversion), securities, cash or other property, each Debenture shall
thereafter be convertible into

                                      109
<PAGE>
 
the kind and, in the case of a Transaction which does not involve a Fundamental
Change, amount of securities, cash and other property receivable upon the
consummation of such Transaction by a holder of that number of shares of Common
Stock into which a Debenture was convertible immediately prior to such
Transaction, or (ii) in the case of a Transaction involving a Common Stock
Fundamental Change, common stock, each Debenture shall thereafter be convertible
(in the manner described herein) into common stock of the kind received by
holders of Common Stock (but in each case after giving effect to any adjustment
discussed in paragraphs (b) and (c) relating to a Fundamental Change if such
Transaction constitutes a Fundamental Change). The holders of Debentures or
Preferred Securities will have no voting rights with respect to any Transaction
described in this section.

                  (b)  If any Fundamental Change occurs, then the Conversion
Price in effect will be adjusted immediately after such Fundamental Change as
described in paragraph (c) below. In addition, in the event of a Common Stock
Fundamental Change, each Debenture shall be convertible solely into common stock
of the kind received by holders of Common Stock as a result of such Common Stock
Fundamental Change.

                  (c)  The Conversion Price in the case of any Transaction
involving a Fundamental Change will be adjusted immediately after such
Fundamental Change:

                       (1)  in the case of a Non-Stock Fundamental Change,
                  the Conversion Price of the Debentures will thereupon become
                  the lower of (A) the Conversion Price in effect immediately
                  prior to such Non-Stock Fundamental Change, but after giving
                  effect to any other prior adjustments, and (B) the result
                  obtained by multiplying the greater of the Applicable Price or
                  the then applicable Reference Market Price by a fraction of
                  which the numerator will be $50 and the denominator will be
                  (x) the amount of the redemption price for the Debenture if
                  the redemption date were the date of such Non-Stock
                  Fundamental Change (or, for the period commencing on the first
                  date of original issuance of the Debentures and through
                  December 1, 1997, and the twelve-month periods commencing
                  December 2, 1997 and December 2, 1998, the product of
                  106.75, 106.075 and 105.400, respectively,

                                      110

                  multiplied by $50) plus (y) any then-accrued and unpaid
                  interest on the Debentures; and

                       (2)  in the case of a Common Stock Fundamental Change,
                  the Conversion Price of the Debentures in effect immediately
                  prior to such Common Stock Fundamental Change, but after
                  giving effect to any other prior adjustments, will thereupon
                  be adjusted by multiplying such Conversion Price by a fraction
                  of which the numerator will be the Purchaser Stock Price and
                  the denominator will be the Applicable Price; provided,
                  however, that in the event of a Common Stock Fundamental
                  Change in which (A) 100% of the value of the consideration
                  received by a holder of Common Stock is common stock of the
                  successor, acquiror, or other third party (and cash, if any,
                  is paid only with respect to any fractional interests in such
                  common stock resulting from such Common Stock Fundamental
                  Change) and (B) all of the Common Stock will have been
                  exchanged for, converted into, or acquired for common stock
                  (and cash with respect to fractional interests) of the
                  successor, acquiror, or other third party, the Conversion
                  Price of the Debentures in effect immediately prior to such
                  Common Stock Fundamental Change will thereupon be adjusted by
                  multiplying such Conversion Price by a fraction of which the
                  numerator will be one and the denominator will be the number
                  of shares of common stock of the successor, acquiror, or other
                  third party received by a holder of one share of Common Stock
                  as a result of such Common Stock Fundamental Change.

         SECTION 13.6. Notice of Adjustments of Conversion Price.  Whenever the
Conversion Price is adjusted as herein provided:

                  (a)  the Company shall compute the adjusted conversion price
and shall prepare a certificate signed by the Chief Financial Officer or the
Treasurer of the Company setting forth the adjusted conversion price and showing
in reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed with the Trustee, the Conversion Agent and
the transfer agent for the Preferred Securities and the Debentures; and

                                      111
<PAGE>
 
                  (b)  a notice stating the Conversion Price has been adjusted
and setting forth the adjusted Conversion Price shall as soon as practicable be
mailed by the Company to all record holders of Preferred Securities and the
Debentures at their last addresses as they appear upon the stock transfer books
of the Company and the Trust and the Securities Registrar.

         SECTION 13.7. Prior Notice of Certain Events.
              In case:

                       (i)   the Company shall (A) declare any dividend (or
         any other distribution) on its Common Stock, other than (x) a dividend
         payable in shares of Common Stock or (y) a dividend payable in cash
         that would not require an adjustment pursuant to Section 13.4(c) or 
         (d) or (B) authorize a tender or exchange offer that would require an
         adjustment pursuant to Section 13.4(e);

                       (ii)  the Company shall authorize the granting to all
         holders of Common Stock of rights or warrants to subscribe for or
         purchase any shares of stock of any class or series or of any other
         rights or warrants;

                       (iii) of any reclassification of Common Stock (other
         than a subdivision or combination of the outstanding Common Stock, or a
         change in par value, or from par value to no par value, or from no par
         value to par value), or of any consolidation or merger to which the
         Company is a party and for which approval of stockholders of the
         Company shall be required, or of the sale or transfer of all or
         substantially all of the assets of the Company or of any compulsory

<PAGE>
 
Holders at their last addresses as they shall appear in the Security Register,
at least 15 days prior to the applicable record or effective date hereinafter
specified, a notice stating (x) the date on which a record (if any) is to be
taken for the purpose of such dividend, distribution, rights or warrants or, if
a record is not to be taken, the date as of which the holders of Common Stock of
record to be entitled to such dividend, distribution, rights or warrants are to
be determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, share exchange, dissolution, liquidation or winding up
is expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up (but no failure to mail such notice or
any defect therein or in the mailing thereof shall affect the validity of the
corporate action required to be specified in such notice).

         SECTION 13.8. Dividend or Interest Reinvestment Plans. Notwithstanding
anything to the contrary in this Article 13, the issuance of any shares of
Common Stock pursuant to any plan providing for the reinvestment of dividends or
interest payable on securities of the Company and the investment of additional
optional amounts in shares of Common Stock under any such plan, and the issuance
of any shares of Common Stock or options or rights to purchase such shares
pursuant to any employee benefit plan or program of the Company or pursuant to
any option, warrant, right or exercisable, exchangeable or convertible security
outstanding as of the date the Debentures were first issued, shall not be deemed
to constitute an issuance of Common Stock or exercisable, exchangeable or
convertible securities by the Company to which any of the adjustment provisions
described above applies. There shall also be no adjustment of the Conversion
Price in case of the issuance of any stock (or securities convertible into or
exchangeable for stock) of the Company except as specifically described in this
Article 13.

         SECTION 13.9. Certain Additional Rights.

         In case the Company shall, by dividend or otherwise, declare or make a
distribution on its Common Stock referred to in Section 13.4(c) or 13.4(d)
(including, without limitation, dividends or distributions referred to in the
last sentence of Section 13.4(c)), the Holders of the Debentures, upon the
conversion thereof subsequent to the close of business on the date fixed for the
determination of stockholders entitled to receive such distribution and prior to
the effectiveness of the Conversion Price adjustment in respect of such
distribution, shall also be entitled to receive for each share of Common Stock
into which the Debentures are converted, the portion of the shares of Common
Stock, rights, warrants, evidences of indebtedness, shares of capital stock,
cash and assets so distributed applicable to one share of Common Stock;
provided, however, that, at the election of the Company (whose election shall be
- --------  -------
evidenced by a resolution of the Board of Directors) with respect to all Holders
so converting, the Company may, in lieu of distributing to such Holder any
portion of such distribution not consisting of cash or securities of the
Company, pay such Holder an amount in cash equal to the fair market value
thereof (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of
Directors). If any conversion of Debentures described in the immediately
preceding sentence occurs prior to the payment date for a distribution to
holders of Common Stock which the Holder of Debentures so converted is entitled
to receive in accordance with the immediately preceding sentence, the Company
may elect (such election to be evidenced by a resolution of the Board of
Directors) to distribute to such Holder a due bill for the shares of Common
Stock, rights, warrants, evidences of indebtedness, shares of capital stock,
cash or assets to which such Holder is so entitled, provided, that such due bill
(i) meets any applicable requirements of the principal national securities
exchange or other market on which the Common Stock is then traded and 
(ii) requires payment or delivery of such shares of Common Stock, rights,
warrants, evidences of indebtedness, shares of capital stock, cash or assets no
later than the date of payment or delivery thereof to holders of shares of
Common Stock receiving such distribution.

         SECTION 13.10. Restrictions on Common Stock Issuable Upon Conversion.

                  (a)  Shares of Common Stock to be issued upon conversion of a
Debenture in respect of Restricted Preferred Securities shall bear such
restrictive legends as the Company may provide in accordance with applicable
law.

                  (b)  If shares of Common Stock to be issued upon conversion of
a Debenture in respect of Restricted Preferred Securities are to be registered
in a name other than that of the Holder of such Preferred Security, then the
Person in whose name such shares of Common Stock are to be registered must
deliver to the Conversion Agent a certificate satisfactory to the Company and
signed by such Person, as to compliance with the restrictions on transfer
applicable to such Preferred Security. Neither the Trustee nor any Conversion
Agent or Registrar shall be required to register in a name other than that of
the Holder shares of Common Stock issued upon conversion of any such Debenture
in respect of such Preferred Securities not so accompanied by a properly
completed certificate.

         SECTION 13.11. Trustee Not Responsible for Determining Conversion 
Price or Adjustments.

         Neither the Trustee nor any Conversion Agent shall at any time be under
any duty or responsibility to any Holder of any Debenture or to any holder of a
Preferred Security to determine whether any facts exist which may require any
adjustment of the Conversion Price, or with respect to the nature or extent of
any such adjustment when made, or with respect to the method employed, or herein
or in any supplemental indenture provided to be employed, in making the same.
Neither the Trustee nor any Conversion Agent shall be accountable with respect
to the validity or value (or the kind of account) of any shares of Common Stock
or of any securities or property, which may at any time be issued or delivered
upon the conversion of any Debenture; and neither the Trustee nor any Conversion
Agent makes any representation with respect thereto. Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to make any
cash payment or to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property upon the surrender of any
Debenture for the purpose of conversion, or, except as expressly herein
provided, to comply with any of the cove-

undivided beneficial interests in the assets of the Issuer, the Issuer is
issuing 9,000,000 (11,000,000 if the over-allotment option is exercised in full)
of its 6 3/4% Convertible Quarterly Income Preferred Securities (liquidation

Guarantee shall be subordinated to the rights of Holders of Preferred Securities
to receive Guarantee Payments (as defined herein) under this Guarantee;


               NOW, THEREFORE, in consideration of the purchase by each Holder

Agreement limits, qualifies or conflicts with the duties imposed by Sections 310

Guarantee Trustee may request in writing, within 30 days after the receipt by
the Guarantor of any such request, a List of Holders as of a date not more than
15 days prior to the time such list is furnished, in each case to the extent
such information is in the possession or control of the Guarantor and is not
identical to a previously supplied list of Holders or has not otherwise been
received by the Guarantee Trustee. Notwithstanding the foregoing, the Guarantor
shall not be obligated to provide such List of Holders at any time the Preferred
Securities are represented by one or more Global Certificates (as defined in the
Indenture). The Guarantee Trustee may destroy any List of Holders previously
given to it on receipt of a new List of Holders.

               (b)  The Guarantee Trustee shall comply with its obligations

Act.

<PAGE>
 
to the Guarantee Trustee such evidence of compliance with such conditions
precedent, if any, provided for in this Guarantee Agreement that relate to any
of the matters set forth in Section 314(c) of the Trust Indenture Act.  Any
certificate or opinion required to be given by an officer pursuant to Section
314(c)(1) may be given in the form of an Officers' Certificate.

                  SECTION 2.6.  Events of Default; Waiver. The Holders of a
Majority in Liquidation Preference of the Securities may, by vote, on behalf of
the Holders, waive any past Event of Default and its consequences. Upon such
waiver, any such Event of Default shall cease to exist, and any Event of Default
arising therefrom shall be deemed to have been cured, for every purpose of this
Guarantee Agreement, but no such waiver shall extend to any subsequent or other
default or Event of Default or impair any right consequent therefrom.

                  SECTION 2.7.  Event of Default; Notice. (a) The Guarantee
Trustee shall, within 90 days after the occurrence of an Event of Default,
transmit by mail, first class postage prepaid, to the Holders, notices of all
Events of Default known to the Guarantee Trustee, unless such defaults have been
cured before the giving of such notice, provided, that, except in the case of a
default in the payment of a Guarantee Payment, the Guarantee Trustee shall be
protected in withholding such notice if and so long as the Board of Directors,
the executive committee or a trust committee of directors and/or Responsible
Officers of the Guarantee Trustee in good faith determines that the withholding
of such notice is in the interests of the Holders.

                  (b)  The Guarantee Trustee shall not be deemed to have
knowledge of any Event of Default unless the Guarantee Trustee shall have
received written notice, or a Responsible Officer charged with the
administration of the Trust Agreement shall have obtained written notice, of
such Event of Default.

                  SECTION 2.8.  Conflicting Interests. The Trust Agreement and

              POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

                  SECTION 3.1.  Powers and Duties of the Guarantee Trustee. (a)
This Guarantee Agreement shall be held by the Guarantee Trustee for the benefit
of the Holders, and the Guarantee Trustee shall not transfer this Guarantee
Agreement to any Person except a Holder exercising his or her rights pursuant to
Section 5.4(iv) or to a Successor Guarantee Trustee on acceptance by such
Successor Guarantee Trustee of its appointment to act as Successor Guarantee
Trustee. The right, title and interest of the Guarantee Trustee shall
automatically vest in any Successor Guarantee Trustee, upon acceptance by such
Successor Guarantee Trustee of its appointment hereunder, and such vesting and
cessation of title shall be effective whether or not conveyancing documents have
been executed and delivered pursuant to the appointment of such Successor
Guarantee Trustee.

                  (b)  If an Event of Default actually known to the Responsible
Officer of the Guarantee Trustee has occurred and is continuing, the Guarantee
Trustee shall enforce this Guarantee Agreement for the benefit of the Holders.

                  (c)  The Guarantee 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 Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6) and is
actually known to the Responsible Officer of the Guarantee Trustee, the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee 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.

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


                                       8
<PAGE>
 
               (i)  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 Guarantee Trustee shall
               be determined solely by the express provisions of this Guarantee
               Agreement, and the Guarantee Trustee shall not be liable except
               for the performance of such duties and obligations as are
               specifically set forth in this Guarantee Agreement; and

                  (B)  in the absence of bad faith on the part of the Guarantee
               Trustee, the Guarantee 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 Guarantee Trustee and conforming to the requirements of this
               Guarantee 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 Guarantee
               Trustee, the Guarantee Trustee shall be under a duty to examine
               the same to determine whether or not they conform to the
               requirements of this Guarantee Agreement;

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

               (iii)  the Guarantee 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 Preference of the Securities relating to
               the time, method and place of con-

                                       9
<PAGE>
 
               ducting any proceeding for any remedy available to the Guarantee
               Trustee, or exercising any trust or power conferred upon the
               Guarantee Trustee under this Guarantee Agreement; and

               (iv)  no provision of this Guarantee Agreement shall require the
               Guarantee 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 Guarantee 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 this Guarantee Agreement or
               adequate indemnity against such risk or liability is not
               reasonably assured to it.

                  SECTION 3.2. Certain Rights of Guarantee Trustee. (a) Subject
to the provisions of Section 3.1:

                  (i)  The Guarantee Trustee may rely and shall be fully
               protected in acting or refraining from acting upon any
               resolution, certificate, statement, proxy, instrument, opinion,
               report, notice, request, direction, consent, order, bond,
               debenture, note, other evidence of indebtedness or other paper or
               document believed by it to be genuine and to have been signed,
               sent or presented by the proper party or parties.

                  (ii)  Any direction or act of the Guarantor contemplated by
               this Guarantee Agreement shall be sufficiently evidenced by an
               Officers' Certificate unless otherwise prescribed herein.

                  (iii)  Whenever, in the administration of this Guarantee
               Agreement, the Guarantee Trustee shall deem it desirable that a
               matter be proved or established before taking, suffering or
               omitting to take any

                                      10
<PAGE>
 
               action hereunder, the Guarantee Trustee (unless other evidence is
               herein specifically prescribed) may, in the absence of bad faith
               on its part, request and rely upon an Officers' Certificate
               which, upon receipt of such request from the Guarantee Trustee,
               shall be promptly delivered by the Guarantor.

                  (iv)  The Guarantee Trustee may consult with legal counsel,
               and the advice or opinion of such legal counsel with respect to
               legal matters shall be full and complete authorization and
               protection in respect of any action taken, suffered or omitted to
               be taken by it hereunder in good faith and in accordance with
               such advice or opinion.  Such legal counsel may be legal counsel
               to the Guarantor or any of its Affiliates and may be one of its
               employees.  The Guarantee Trustee shall have the right at any
               time to seek instructions concerning the administration of this
               Guarantee Agreement from any court of competent jurisdiction.

                  (v)  The Guarantee Trustee shall be under no obligation to
               exercise any of the rights or powers vested in it by this
               Guarantee Agreement at the request or direction of any Holder,
               unless such Holder shall have provided to the Guarantee Trustee
               such adequate security and indemnity as would satisfy a
               reasonable person in the position of the Guarantee Trustee,
               against the costs, expenses (including attorneys' fees and
               expenses) and liabilities that might be incurred by it in
               complying with such request or direction, including such
               reasonable advances as may be requested by the Guarantee Trustee;
               provided that, nothing contained in this Section 3.2(a)(v) shall
               be taken to relieve the Guarantee Trustee, upon the occurrence of
               an Event of Default, of its obligation to exercise the rights and
               powers vested in it by this Guarantee 


                                      11
<PAGE>
 
               Agreement and use the same degree of care and skill in the
               exercise thereof as a prudent person would exercise or use under
               the circumstances in the conduct of his or her own affairs.

                  (vi)  The Guarantee 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, direction, consent, order, bond, debenture, note, other
               evidence of indebtedness or other paper or document, but the
               Guarantee Trustee, in its discretion, may make such further
               inquiry or investigation into such facts or matters as it may see
               fit.

                  (vii)  The Guarantee 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 or any Affiliate, and
               the Guarantee Trustee shall not be responsible for any misconduct
               or negligence on the part of any such agent or attorney appointed
               with due care by it hereunder.

                  (viii)  Whenever in the administration of this Guarantee
               Agreement the Guarantee Trustee shall deem it desirable to
               receive instructions with respect to enforcing any remedy or
               right or taking any other action hereunder, the Guarantee Trustee
               (A) may request instructions from the Holders of a Majority in
               Liquidation Preference of the Securities, (B) may refrain from
               enforcing such remedy or right or taking such other action until
               such instructions are received, and (C) shall be protected in
               acting in accordance with such instructions.

                  (b)  No provision of this Guarantee Agreement shall be deemed
to impose any duty or obligation on the Guarantee 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

                                      12
<PAGE>
 
be illegal, or in which the Guarantee Trustee shall be unqualified or
incompetent in accordance with applicable law, to perform any such act or acts
or to exercise any such right, power, duty or obligation. No permissive power or
authority available to the Guarantee Trustee shall be construed to be a duty to
act in accordance with such power and authority.

                  SECTION 3.3.  Indemnity. The Guarantor agrees to indemnify the
Guarantee Trustee for, and to hold it harmless against, any loss, liability or
expense incurred without negligence or bad faith on the part of the Guarantee
Trustee, arising out of or in connection with the acceptance or administration
of this Guarantee Agreement, including the reasonable costs and expenses of
defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. The Guarantee Trustee
will not claim or exact any lien or charge on any Guarantee Payment as a result
of any amount due to it under this Guarantee Agreement.

                  SECTION 4.1.  Guarantee Trustee; Eligibility. (a) There shall
at all times be a Guarantee Trustee which shall:

                  (i)  not be an Affiliate of the Guarantor; and

                  (ii)  be a Person that is eligible pursuant to the Trust

               meeting the requirements of Section 310(a) of the Trust Indenture
               Act.  If such corporation publishes reports of condition at least
               annually, pursuant to law or to the requirements of the
               supervising or examining authority, then, for the purposes of
               this Section and to the extent permitted by the Trust Indenture
               Act, the combined capital and surplus of such corporation shall
               be deemed to be its 

                                      13
<PAGE>
 
               combined capital and surplus as set forth in its most recent
               report of condition so published.

                  (b)  If at any time the Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Guarantee Trustee shall immediately
resign in the manner and with the effect set out in Section 4.2(c).

                  (c)  If the Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Guarantee Trustee and Guarantor shall in all respects comply
with the provisions of Section 310(b) of the Trust Indenture Act.

                  SECTION 4.2.  Appointment, Removal and Resignation of the
Guarantee Trustee. (a) Subject to Section 4.2(b) the Guarantee Trustee may be
appointed or removed without cause at any time by the Guarantor.

                  (b)  The Guarantee Trustee shall not be removed until a
Successor Guarantee Trustee has been appointed and has accepted such appointment
by written instrument executed by such Successor Guarantee Trustee and delivered
to the Guarantor.

                  (c)  The Guarantee Trustee appointed hereunder shall hold
office until a Successor Guarantee Trustee shall have been appointed or until
its removal or resignation. The Guarantee Trustee may resign from office
(without need for prior or subsequent accounting) by an instrument in writing
executed by the Guarantee Trustee and delivered to the Guarantor, which
resignation shall not take effect until a Successor Guarantee Trustee has been
appointed and has accepted such appointment by an instrument in writing executed
by such Successor Guarantee Trustee and delivered to the Guarantor and the
resigning Guarantee Trustee.

                  (d)  If no Successor Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 60
days after delivery to the Guarantor of an instrument of resignation, the
resigning Guarantee Trustee may petition, at the expense of the Guarantor, any
court of competent jurisdiction for appointment of a Successor Guarantee
Trustee. Such court

                                      14
<PAGE>
 
may thereupon, after prescribing such notice, if any, as it may deem proper,
appoint a Successor Guarantee Trustee.

unconditionally agrees to pay in full to the Holders the Guarantee Payments
(without duplication of amounts theretofore paid by or on behalf of the Issuer),
as and when due, regardless of any defense, right of set-off or counterclaim
which the Issuer may have or assert other than the defense of payment. The

demands.

                  SECTION 5.3.  Obligations Not Affected. The obligations,

be performed or observed by the Issuer;

                  (b)  the extension of time for the payment by the Issuer of
all or any portion of the Distributions (other than an extension of time for
payment of Distributions that results from the extension of any interest payment
period on the Debentures as so provided

                                      15

the performance of any other obligation under, arising out of, or in connection
with, the Preferred Securities;

                  (c)  any failure, omission, delay or lack of diligence on the
part of the Holders to enforce, assert or exercise any right, privilege, power
or remedy conferred on the Holders pursuant to the terms of the Preferred
Securities, or any action on the part of the Issuer granting indulgence or
extension of any kind;

                  (d)  the voluntary or involuntary liquidation, dissolution,
sale of any collateral, receivership, insolvency, bankruptcy, assignment for the
benefit of creditors, reorganization, arrangement, composition or readjustment

assets of the Issuer;

                  (e)  any invalidity of, or defect or deficiency in, the
Preferred Securities;

                  (f)  the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or

                  (g)  any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor, it being
the intent of this Section 5.3 that the obligations of the Guarantor hereunder
shall be absolute and unconditional under any and all circumstances.

                  There shall be no obligation of the Holders or the Guarantee
Trustee to give notice to, or obtain the consent of, the Guarantor with respect
to the happening of any of the foregoing.

                  SECTION 5.4.  Rights of Holders. The Guarantor expressly
acknowledges that: (i) this Guarantee Agreement will be deposited with the
Guarantee Trustee to be held for the benefit of the Holders; (ii) the Guarantee
Trustee has the right to enforce this Guarantee Agreement on behalf of the

ducting any proceeding for any remedy available to the Guarantee Trustee in
respect of this Guarantee Agreement or to direct the exercise of any trust or
power conferred upon the Guarantee Trustee under this Guarantee Agreement; (iv)
any Holder may institute a legal proceeding directly against the Guarantor to
enforce its rights under this Guarantee Agreement, without first instituting a
legal proceeding against the Guarantee Trustee, the Issuer or any other Person;
and (v) if an Event of Default with respect to the Debentures constituting the
failure to pay interest or principal on the Debentures on the date such interest
or principal is otherwise payable has occurred and is continuing, then any
Holder shall have the right, which is absolute and unconditional, to proceed
directly against the Guarantor to obtain Guarantee Payments without first
waiting to determine if the Guarantee Trustee has enforced this Guarantee
Agreement or instituting a legal proceeding against the Issuer, the Guarantee
Trustee or any other Person.

                  SECTION 5.5.  Guarantee of Payment. This Guarantee Agreement
creates a guarantee of payment and not of collection. This Guarantee Agreement
will not be discharged except by payment of the Guarantee Payments in full

distribution of Debentures to Holders as provided in the Trust Agreement.

                  SECTION 5.6.  Subrogation. The Guarantor shall be subrogated
to all (if any) rights of the Holders against the Issuer in respect of any
amounts paid to the Holders by the Guarantor under this Guarantee Agreement and
shall have the right to waive payment by the Issuer pursuant to Section 5.1;
provided, however, that the Guarantor shall not (except to the extent required
by mandatory provisions of law) be entitled to enforce or exercise any rights
which it may acquire by way of subrogation or any indemnity, reimbursement or
other agreement, in all cases as a result of payment under this Guarantee
Agreement, if, at the time of any such payment, any amounts are due and unpaid
under this Guarantee Agreement. If any amount shall be paid to the Guarantor in
violation of the preceding sentence, the Guarantor agrees to hold such amount in
trust for the Holders and to pay over such amount to the Holders.

acknowledges that its obligations hereunder are independent of the obligations
of the Issuer with respect to the Preferred Securities and that the Guarantor
shall be liable as principal and as debt or hereunder to make Guarantee Payments
pursuant to the terms of this Guarantee Agreement notwithstanding the occurrence
of any event referred to in subsections (a) through (g), inclusive, of Section
5.3 hereof.

Plan, and the declaration of a dividend of such rights or the issuance of

Default" under the Indenture with respect to the Debentures and (b) in respect
of which the Guarantor shall not have taken reasonable steps to cure, (ii) the

Period, or any extension thereof, shall be continuing.

directly or indirectly 100% ownership of the Common Securities, provided that
certain successors which are permitted by the Indenture may succeed to the
Guarantor's ownership of the Common Securities, (ii) not to voluntarily
terminate, wind-up or liquidate the Issuer, except (a) in connection with a
distribution of the Debentures to the holders of the Preferred Securities in
liquidation of the Issuer or (b) in connection with certain mergers,

its reasonable efforts, consistent with the terms and provisions of the Trust
Agreement, to cause the Issuer to remain classified as a grantor trust and not
as an association taxable as a

corporation for United States Federal income tax purposes, (iv) for so long as

upon the conversion of all the Debentures then outstanding, (vi) to deliver
shares of Common Stock upon an election by the Holders to convert such Preferred
Securities into Common Stock and (vii) to honor all obligations relating to the
conversion or exchange of the Preferred Securities into or for Common Stock or
Debentures.

liquidation of the Issuer or (iv) upon the distribution, if any, of Common Stock

holders' Preferred Securities into Common Stock. Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated, as
the case may be, if at any time any Holder must restore payment of any sums paid
with respect to Preferred Securities or this Guarantee Agreement.

surrendered for conversion or exchange in order to receive such number of shares

  2. Shelf Registration.  (a)  The Company and the Trust shall, within 120
calendar days following the first Time of Delivery (as defined in the Purchase
Agreement), file with the Commission a Shelf Registration Statement relating to
the offer and sale of the Registrable Securities and, thereafter, shall use
their  reasonable best efforts to cause such Shelf Registration Statement to be
declared effective under the Act within 180 calendar days after the Time of
Delivery; provided, however, that no Holder shall be entitled to be named as a
selling securityholder in the Shelf Registration Statement or to use the
Prospectus forming a part thereof for resales of Registrable Securities unless
such Holder is an Electing Holder.

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

      (i)  To keep the Shelf Registration Statement continuously effective
  (subject to any Suspension Period (as defined below)) in order to permit the
  Prospectus forming part thereof to be usable by Electing Holders for resales
  of Registrable Securities for a period of three years from the Time of
  Delivery (as defined in the Purchase Agreement), or

                                       4
<PAGE>
 
  such shorter period that will terminate upon the earliest of the following:
  (A) when all the Preferred Securities covered by the Shelf Registration
  Statement have been sold pursuant to the Shelf Registration Statement; (B)
  when all Debentures issued to Holders in respect of Preferred Securities that
  had not been sold pursuant to the Shelf Registration Statement have been sold
  pursuant to the Shelf Registration Statement; (C) when all shares of Common
  Stock issued upon conversion of any such Preferred Securities or any such
  Debentures that have not been sold pursuant to the Shelf Registration
  Statement have been sold pursuant to the Shelf Registration Statement; and (D)
  when, in written opinion of counsel to the Trust and the Company, all
  outstanding Registrable Securities held by persons which are not affiliates of
  the Trust or the Company may be resold without registration under the Act
  pursuant to Rule 144(k) under the Act or any successor provision thereto (in
  any such case, such period being called the "Effectiveness Period").

      (ii)  After the Effective Time of the Shelf Registration Statement,
  reasonably promptly upon the request of any Holder that is not then an
  Electing Holder identified as a selling securityholder in the Prospectus at
  the Effective Time, to take any action reasonably necessary to enable such
  Holder to use the Prospectus forming a part thereof for resales of Registrable
  Securities, including, without limitation, any action necessary to identify
  such Holder as a selling securityholder in the Shelf Registration Statement;
  provided, however, that nothing in this subparagraph shall relieve such Holder
  of the obligation to return a completed and signed Notice and Questionnaire to
  the Trust in accordance with Section 3(a)(2) hereof and to provide to the
  Trust and the Company, in writing, any information with respect to such Holder
  or the Registrable Securities held by such Holder as is, in the reasonable
  opinion of counsel to the Trust or the Company, required under applicable law
  to enable such Holder to use such Prospectus for resales of such Registrable
  Securities; and

      (iii)  If at any time prior to the end of the Effectiveness Period, the
  Preferred Securities are convertible into securities other than Common Stock,
  the Company and the Trust shall, or shall cause any successor under the Trust
  Agreement to, cause such securities to be included in the Shelf Registration
  Statement no later than the date on which the Preferred Securities may then be
  convertible into such securities.

  (c) If (i) on or prior to the date 120 days after the Time of Delivery a Shelf
Registration Statement has not been filed with the Commission or (ii) on or
prior to the date 180 days after the last Time of Delivery such Shelf
Registration Statement has not been declared effective (each such event, a
"Registration Default"), additional interest ("Liquidated Damages") will accrue
on the Debentures, and, accordingly, additional distributions will accrue on the
Preferred Securities, from and including the day following such Registration
Default until such date as the Shelf Registration Statement is filed or declared
effective, as the case may be. Liquidated Damages will be paid quarterly in
arrears (subject to the Company's right to defer the payment of Liquidated
Damages during any Extension Period (as defined in the Indenture)), with the
first quarterly payment due on the first interest or distribution payment date,
as applicable, following the date on which such Liquidated Damages begin to
accrue, and will

                                       5
<PAGE>
 
accrue at a rate per annum equal to an additional one-quarter of one percent
(0.25%) of the principal amount or liquidation amount, as applicable, to and
including the 90th day following such Registration Default and one-half of one
percent (0.50%) thereof from and after the 91st day following such Registration
Default.  In the event that the Shelf Registration Statement ceases to be
effective during the Effectiveness Period for more than 90 days, whether or not
consecutive, during any 12-month period, then the interest rate borne by the
Debentures and the distribution rate borne by the Preferred Securities will each
increase by an additional one-half of one percent (0.50%) per annum from the
91st day of the applicable 12-month period such Shelf Registration Statement
ceases to be effective until such time as the earlier to occur of the Shelf
Registration Statement again becoming effective and the end of the Effectiveness
Period.

     (d) The Company and the Trust shall each be deemed not to have used its
best efforts to keep the Shelf Registration Statement effective during the
Effectiveness Period if either the Trust or the Company voluntarily takes any
action that would result in Electing Holders not being able to offer and sell
any of their Registrable Securities during such period, unless (i) such action
is required by applicable law, (ii)  upon the occurrence of any event
contemplated by paragraph 3(d)(2)(iii) below, and such action is taken by the
Trust or the Company in good faith and for valid business reasons or (iii) the
continued effectiveness of the Shelf Registration Statement would require the
Trust to disclose a material financing, acquisition or other corporate
development, and the proper officers of the Company shall have determined in
good faith that such disclosure is not in the best interest of the Company and
its stockholders and, in the case of clause (ii) above, the Company and the
Trust thereafter promptly comply with the requirements of paragraph 3(j) below.
Any such period during which the Company and the Trust are permitted to suspend
the effectiveness of the Shelf Registration Statement is referred to herein as
the "Suspension Period."

     3.   Registration Procedures.  In connection with the Shelf Registration
Statement, the following provisions shall apply:

          (a) (1)  The Company shall not be required to take any action to name
     such Holder as a selling securityholder in the Shelf Registration Statement
     or to enable such Holder to use the Prospectus forming a part thereof for
     resales of Registrable Securities until such Holder has returned a
     completed and signed Notice and Questionnaire to the Company and the Trust
     and provided to the Trust and the Company such information with respect to
     such Holder or the Registrable Securities held by such Holder as is, in the
     reasonable opinion of counsel to the Trust or the Company, required to
     enable such Holder to use the Prospectus for resales of Registrable
     Securities.

          (2) Not less than 40 calendar days prior to the Effective Time of the
     Shelf Registration Statement, the Company or the Trust shall mail the
     Notice and Questionnaire to each Holder.  No Holder shall be entitled to be
     named as a selling securityholder in the Shelf Registration Statement as of
     the Effective Time, and no Holder shall be entitled to use the Prospectus
     forming a part thereof for resales of Registrable Securities at any time,
     unless such Holder has returned a completed and signed Notice and
     Questionnaire

                                       6
<PAGE>
 
     to the Company and the Trust and provided to the Trust and the Company such
     information with respect to such Holder of the Registrable Securities held
     by such Holder as is, in the reasonable opinion of counsel to the Trust or
     the Company, required to enable such Holder to use the Prospectus for
     resales of Registrable Securities provided, however, only Holders who have
                                       --------  -------                       
     completed and returned the Notice and Questionnaire and any such additional
     information requested of such Holder to the Company on or before the day
     that is ten days prior to the Effective Time shall be entitled to be named
     as a selling securityholder in the Shelf Registration Statement as of the
     Effective Time.

          (3) The term "Electing Holder" shall mean any Holder that has returned
     a completed and signed Notice and Questionnaire to the Company in
     accordance with Section 3(a)(1) or 3(a)(2) hereof and provided to the Trust
     and the Company such information with respect to such Holder or the
     Registrable Securities held by such Holder as is, in the reasonable opinion
     of counsel to the Trust or the Company, required to enable such Holder to
     use the Prospectus for resales of Registrable Securities.

          (b) The Company and the Trust shall furnish to each Electing Holder,
     prior to the Effective Time, a copy of the Shelf Registration Statement
     initially filed with the Commission, and shall reasonably promptly furnish
     to such Holders, copies of each amendment thereto and each amendment or
     supplement, if any, to the Prospectus included therein, and shall consider
     in good faith for inclusion in each such document, at the Effective Time
     such comments as such Holders or their counsel reasonably may propose,
     provided, however, that the Company's obligations set forth in this Section
     3(b) shall not require the Company to delay or postpone the Effective Time
     or prevent the Company from otherwise requesting the acceleration of the
     effectiveness of the Shelf Registration Statement.

          (c) The Company and the Trust shall promptly take such action as may
     be necessary so that (i) each of the Shelf Registration Statement and any
     amendment thereto and the Prospectus forming part thereof and any amendment
     or supplement thereto (and each report or other document incorporated
     therein by reference in each case) complies in all material respects with
     the Securities Act and the rules and regulations thereunder, (ii) each of
     the Shelf Registration Statement and any amendment thereto does not, when
     it becomes effective, contain an untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading and (iii) each of the Prospectus
     forming part of the Shelf Registration Statement, and any amendment or
     supplement to such Prospectus, does not at any time during the
     Effectiveness Period include an untrue statement of a material fact or omit
     to state a material fact necessary in order to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading.

          (d) (1)  The Company shall promptly advise the Purchasers and, in the
     case of clause (i), the Electing Holders and, if requested by the
     Purchasers or any such Electing Holder, confirm such advice in writing:

                                       7
<PAGE>
 
               (i)  when the Shelf Registration Statement and any amendment
          thereto has been filed with the Commission and when the Shelf
          Registration Statement or any post-effective amendment thereto has
          become effective; and

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

          (2)  The Company shall promptly advise each Electing Holder of:

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

               (ii)  the receipt by the Company or the Trust of any notification
          with respect to the suspension of the qualification of the securities
          included in the Shelf Registration Statement for sale in any
          jurisdiction or the initiation of any proceeding for such purpose; and

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

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

          (f) The Company and the Trust shall furnish to each Electing Holder,
     without charge, at least one copy of the Shelf Registration Statement and
     all post-effective amendments thereto, including financial statements and
     schedules, and, if such Holder so requests in writing, all reports, other
     documents and exhibits that are filed with or incorporated by reference in
     the Shelf Registration Statement.

          (g) The Company and the Trust shall, during the Effectiveness Period,
     deliver to each Electing Holder, without charge, as many copies of the
     Prospectus (including each preliminary Prospectus) included in the Shelf
     Registration Statement and any amendment or supplement thereto as such
     Electing Holder may reasonably request; and the Company and the Trust each
     consents (except during the continuance of any event described in Section
     3(d)(2)(iii) above or during any Suspension Period)  to the use of

                                       8
<PAGE>
 
     the Prospectus and any amendment or supplement thereto by each of the
     Electing Holders in connection with the offering and sale of the
     Registrable Securities covered by the Prospectus and any amendment or
     supplement thereto during the Effectiveness Period.

          (h) Prior to any offering of Registrable Securities pursuant to the
     Shelf Registration Statement, the Company and the Trust shall (1) register
     or qualify or cooperate with the Electing Holders and their respective
     counsel in connection with the registration or qualification of such
     Registrable Securities for offer and sale under the securities or "blue
     sky" laws of such jurisdictions within the United States as any Electing
     Holder may reasonably request, (2) keep such registrations or
     qualifications in effect (subject to any Suspension Period) and comply with
     such laws so as to permit the continuance of offers and sales in such
     jurisdictions for so long as may be necessary to enable any Electing Holder
     or underwriter, if any, to complete its distribution of Registrable
     Securities pursuant to the Shelf Registration Statement, and (3) take any
     and all other actions necessary or advisable to enable the disposition in
     such jurisdictions of such Registrable Securities; provided, however, that
     in no event shall the Company or the Trust be obligated to (i) qualify
     generally to do business or as a foreign corporation or as a dealer in
     securities in any jurisdiction where each would not otherwise be required
     to so qualify but for this Section 3(h), (ii) file any general consent to
     service of process in any jurisdiction where it is not as of the date
     hereof so subject or (iii) subject itself to taxation in any jurisdiction
     where it is not otherwise so subject.

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

          (j) Upon the occurrence of any event contemplated by paragraph
     3(d)(2)(iii) above, the Company and the Trust shall promptly prepare a
     post-effective amendment or supplement to the Shelf Registration Statement
     or the Prospectus, or any document incorporated therein by reference, or
     file any other required document so that, as thereafter delivered to
     purchasers of the Registrable Securities included therein, the Prospectus
     will not include an untrue statement of a material fact or omit to state
     any material fact necessary to make the statements therein, in the light of
     the circumstances under which they were made, not misleading (except, in
     each case, for an untrue statement of a material fact or omission of a
     material fact made in reliance on and in conformity with written
     information furnished to the Trust or the Company by or on behalf of any
     Electing Holders); provided, however, if the proper officers of the Company
     determine in good faith that  disclosure in the Shelf Registration
     Statement of a material financing, acquisition or other corporate
     transaction would not be in the best interests of the Company and its
     stockholders, the Company and the Trust shall not be

                                       9
<PAGE>
 
     required to prepare and file such amendment, supplement or document for
     such period as such officers shall have determined in good faith is in the
     best interests of the Company.  Upon receipt of written notice from the
     Company or the Trust of the occurrence of any event contemplated by
     paragraph 3(d)(2)(iii) above or of any Suspension Period, each Holder shall
     forthwith discontinue disposition of Registrable Securities until such
     Holder has received copies of the supplemental or amended Prospectus
     required by this paragraph 3(j), or until such Holder is advised by the
     Company or the Trust that the use of the Prospectus may be resumed and, if
     so directed by the Company, such Holder shall deliver to the Company (at
     the Company's expense) all copies then in such Holder's possession of the
     Prospectus covering such Registrable Securities current at the time of such
     notice.

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

          (l) The Company and the Trust shall each use its best efforts to
     comply with all applicable Rules and Regulations, and to make generally
     available to its securityholders as soon as practicable, but in any event
     not later than 18 months after (i) the effective date (as defined in Rule
     158(c) under the Securities Act) of the Shelf Registration Statement, (ii)
     the effective date of each post effective amendment to the Shelf
     Registration Statement, and (iii) the date of each filing by the Company
     with the Commission of an Annual Report on Form 10-K that is incorporated
     by reference in the Shelf Registration Statement, an earnings statement
     of the Company and its subsidiaries complying with Section 11 (a) of the
     Securities Act and the rules and regulations of the Commission thereunder
     (including, at the option of the Company, Rule 158).

          (m) The Company and the Trust shall each use its reasonable best
     efforts to cause the Indenture, the Declaration and the Guarantee to be
     qualified under the Trust Indenture Act in a timely manner.

          (n) In the event of an underwritten offering conducted pursuant to
     Section 6 hereof, the Company and the Trust shall, if requested, promptly
     include or incorporate in a Prospectus supplement or post-effective
     amendment to the Shelf Registration Statement such information as the
     Managing Underwriters reasonably agree should be included therein and to
     which the Company does not reasonably object and shall make all required
     filings of such Prospectus supplement or post-effective amendment as soon
     as practicable after it is notified of the matters to be included or
     incorporated in such Prospectus supplement or post-effective amendment.

                                       10
<PAGE>
 
          (o) The Company and the Trust shall enter into such customary
     agreements (including an underwriting agreement in customary form in the
     event of an underwritten offering conducted pursuant to Section 6 hereof)
     and take all other appropriate action in order to expedite and facilitate
     the registration and disposition of the Registrable Securities, and in
     connection therewith, if an underwriting agreement is entered into, cause
     the same to contain indemnification provisions and procedures reasonably
     similar to those set forth in Section 5 hereof with respect to all parties
     to be indemnified pursuant to Section 5 hereof.

          (p)  The Company and the Trust shall:

               (i)  (A) make reasonably available for inspection by Electing
          Holders, any underwriter participating in any disposition pursuant to
          such Shelf Registration Statement, and any attorney, accountant or
          other agent retained by such holders or any such underwriter all
          relevant financial and other records, pertinent corporate or other
          documents and properties of the Company, its subsidiaries and the
          Trust, and (B) cause the officers, directors, employees, trustees and
          agents of the Company and the Trust to supply all information
          reasonably requested by such Holders or any such underwriter,
          attorney, accountant or agent in connection with the Shelf
          Registration Statement, in each case, as is customary for similar due
          diligence examinations; provided, however, that each Electing Holder
          and its representatives and agents shall execute an agreement (in form
          reasonably acceptable to the Company) providing that all records,
          information and documents that are designated in writing by the
          Company and the Trust, in good faith, as confidential shall be kept
          confidential by such Holders and any such underwriter, attorney,
          accountant or agent, unless such disclosure is made in connection with
          a court proceeding or required by law, or such records, information or
          documents become available to the public generally or through a third
          party without an accompanying obligation of confidentiality; and
          provided further that, if the foregoing inspection and information
          gathering would, in the Company's reasonable judgment, disrupt the
          Company's conduct of its business, such inspection and information
          gathering shall be coordinated on behalf of the Electing Holders and
          the other parties entitled thereto by one counsel designated by and on
          behalf of Electing Holders and other parties (the fees and expenses of
          such counsel to be borne by such Electing Holders except to the extent
          set forth in Section 4);

               (ii)  in connection with any underwritten offering conducted
          pursuant to Section 6 hereof, make such representations and warranties
          to the Holders participating in such underwritten offering and to the
          Managing Underwriters, in form, substance and scope as are customarily
          made by the Company and the Trust to underwriters in primary
          underwritten offerings of equity and convertible preferred and debt
          securities and covering matters including, but not limited to, those
          set forth in the Purchase Agreement;

                                       11
<PAGE>
 
              (iii)  in connection with any underwritten offering conducted
          pursuant to Section 6 hereof, obtain opinions of counsel (which
          counsel may be an employee of the Company) to the Company and the
          Trust (which counsel and opinions (in form, scope and substance) shall
          be reasonably satisfactory to the Managing Underwriters) addressed to
          each Holder participating in such underwritten offering and the
          underwriters, covering such matters as are customarily covered in
          opinions requested in underwritten offerings and such other matters as
          may be reasonably requested by such Holders and underwriters (it being
          agreed that the matters to be covered by such opinions shall include,
          without limitation, as of the date of the opinion and as of the
          Effective Time of the Shelf Registration Statement or most recent
          post-effective amendment thereto, as the case may be, the absence
          from the Shelf Registration Statement and the Prospectus, including
          the documents incorporated by reference therein, of an untrue
          statement of a material fact or the omission of a material fact
          required to be stated therein or necessary to make the statements
          therein not misleading;

               (iv)  in connection with any underwritten offering conducted
          pursuant to Section 6 hereof, obtain "cold comfort" letters and
          updates thereof from the independent public accountants of the Company
          and the Trust, addressed to each Holder participating in such
          underwritten offering (if such Holder has provided such letter,
          representations or documentation, if any, required for such "cold
          comfort" letter to be so addressed) and the underwriters, in customary
          form and covering matters of the type customarily covered in "cold
          comfort" letters in connection with primary underwritten offerings;

               (v)   deliver such documents and certificates as may be
          reasonably requested by any Holders participating in such underwritten
          offering and the Managing Underwriters, if any, including, without
          limitation, certificates to evidence compliance with Section 3(j)
          hereof and with any conditions contained in the underwriting agreement
          or other agreements entered into by the Company and the Trust.

          (q) The Company and the Trust will each use its best efforts to cause
     the Common Stock issuable upon conversion of the Preferred Securities to be
     listed for quotation on the New York Stock Exchange, the Chicago Stock
     Exchange, the Pacific Stock Exchange, the Philadelphia Stock Exchange or
     other stock exchange or trading system on which the Common Stock primarily
     trades on or prior to the Effective Time of the Shelf Registration
     Statement hereunder.

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

                                       12
<PAGE>
 
          (s) Upon receipt of written notice from the Company that a Suspension
     Period is in effect, each Holder shall forthwith discontinue disposition of
     Registrable Securities until such Holder has received copies of the
     supplemental or amended Prospectus required by Section 3(j) hereof, or
     until such Holder is advised in writing by the Company that the use of the
     Prospectus may be resumed, and, if so directed by the Company, such Holder
     shall deliver to the Company (at the Company's expense) all copies then in
     such Holder's possession, of the Prospectus covering such Registrable
     Securities current at the time of receipt of such notice.

     4.   Registration Expenses.    The Company and the Trust shall each bear
all reasonable fees and expenses customarily borne by issuers in a non-
underwritten secondary offering by selling securityholders or in an underwritten
offering, as the case may be, incurred in connection with the performance of its
obligations under Sections 2, 3 and 6 hereof.  In addition, in the event of an
underwritten offering of Registrable Securities conducted pursuant to Section 6
hereof, or if in any other event the Company requires that inspection and
information gathering be coordinated by counsel for the Electing Holders as
provided in Section 3(p)(i) hereof, the Company shall pay the fees and expenses
of a single counsel selected by the Electing Holders of not less than 25% of the
Registrable Securities to be included in such underwritten offering (or, in any
such other event, included in the Shelf Registration Statement) to represent
them.  The Electing Holders participating in such offering (or, in any such
other event, participating in such inspection and information gathering) shall
be responsible, on a pro rata basis based on the respective amount of their
Registrable Securities included in such offering for all fees and expenses of
such counsel in excess of $75,000; provided, however, that the maximum aggregate
amount that the Company shall be required to pay for fees and expenses of
counsel of Electing Holders pursuant to this Section 4 shall be $75,000.

     5.   Indemnification and Contribution.

     (a)  Indemnification by the Company.  Upon the registration of the
          ------------------------------                               
Registrable Securities pursuant to Section 2 hereof, and in consideration of the
agreements of the Electing Holders and any underwriters, selling agents or other
securities professionals contained in Section 5(b) hereof, the Company and the
Trust jointly and severally shall, and each hereby agrees to, indemnify and hold
harmless each Electing Holder and each underwriter, selling agent or other
securities professional, if any, which facilitates the disposition of
Registrable Securities, and each of their respective officers and directors and
each person who controls such Electing Holder, underwriter, selling agent or
other securities professional within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act (each such person being sometimes referred
to as an "Indemnified Person") against any losses, claims, damages or
liabilities, joint or several, to which such Indemnified Person may become
subject under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in any Shelf Registration Statement under which such Registrable
Securities are to be registered under the Securities Act, or any Prospectus
contained therein or any amendment or supplement thereto, or arise out of or are
based upon the omission or alleged omission to state

                                       13
<PAGE>
 
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and the Company and the Trust hereby agree to
reimburse such Indemnified Person for any reasonable legal or other out-of-
pocket expenses reasonably incurred by them in connection with investigating or
defending any such action or claim as such expenses are incurred; provided,
                                                                  -------- 
however, that the Company or the Trust shall not be liable to any such
- -------                                                               
Indemnified Person in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in such Shelf
Registration Statement or Prospectus, or amendment or supplement, in reliance
upon and in conformity with written information furnished to the Company or the
Trust by such Indemnified Person expressly for use therein.

     The foregoing notwithstanding, the Trust and the Company shall not be
liable to the extent that such losses, claims, damages or liabilities arise out
of or are based upon an untrue statement or alleged untrue statement or omission
or alleged omission made in any Prospectus that is a preliminary prospectus if
(i) such Indemnified Person failed to send or deliver a copy of the Prospectus
with or prior to the delivery of written confirmation of the sale of Registrable
Securities giving rise to such losses, claims, damages or liabilities and (ii)
the Prospectus would have corrected such untrue statement or omission.

     In addition, the Trust and the Company shall not be liable to the extent
that any such losses, claims, damages or liabilities arise out of or are based
upon an untrue statement or alleged untrue statement or omission or alleged
omission in a Prospectus (x) if such untrue statement or omission or alleged
untrue statement or omission is corrected in an amendment or supplement to such
Prospectus and (y) having previously been furnished by or on behalf of the Trust
or the Company with copies of the Prospectus as amended or supplemented, such
Indemnified Person thereafter fails to deliver such Prospectus as so amended or
supplemented prior to or concurrently with the sale to the person who purchased
a Registrable Security from such Indemnified Person and who is asserting such
losses, claims, damages or liabilities.

     (b) Indemnification by the Holders and any Agents and Underwriters.  Each
         --------------------------------------------------------------       
Electing Holder agrees, as a consequence of the inclusion of any of such
Holder's Registrable Securities in such Shelf Registration Statement, and each
underwriter, selling agent or other securities professional, if any, which
facilitates the disposition of Registrable Securities shall agree, as a
consequence of facilitating such disposition of Registrable Securities,
severally and not jointly, to (i) indemnify and hold harmless the Company and
the Trust, its directors, trustees, agents and officers who sign any Shelf
Registration Statement and each person, if any, who controls the Company within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act (collectively referred to as the "Indemnified Party"), against any
losses, claims, damages or liabilities to which the Company or such other
persons may become subject, under the Securities Act or otherwise, insofar as
such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in such Shelf Registration Statement or Prospectus,
or any amendment or supplement, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements

                                       14
<PAGE>
 
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company or the Trust by such Holder, underwriter, selling agent
or other securities professional expressly for use therein, and (ii) reimburse
the Company and the Trust for any reasonable legal or other out-of-pocket
expenses reasonably incurred by the Company and the Trust in connection with
investigating or defending any such action or claim as such expenses are
incurred.

     (c) Notices of Claims, Etc.  If any action or proceeding (including any
         ----------------------                                             
governmental investigation or inquiry) shall be brought or asserted against a
Indemnified Person under subsection (a) or an Indemnified Party under subsection
(b) (collectively referred to as the "Indemnified Holder") in respect of which
indemnity may be sought, such Indemnified Holder shall promptly notify the
indemnifying Company and Trust under subsection (a) and the indemnifying
Electing Holders under subsection (b) (collectively the "Indemnifying Party") in
writing (provided that the failure to give such notice shall not relieve the
Indemnifying Party of its obligations pursuant  to this Agreement unless and
only to the extent that such omission results in the loss or compromise of any
material rights or defenses by the Indemnifying Party, as determined by a court
of competent jurisdiction by final judgment), and the Indemnifying Party shall
assume the defense thereof, including the employment of counsel reasonably
satisfactory to such Indemnified Holder and the payment of all expenses in
connection therewith; but the omission so to notify the Indemnifying Party shall
not relieve it from any liability which it may have to any Indemnified Holder
otherwise than under this Section 5.  Such Indemnified Holder shall have the
right to employ separate counsel in any such action and to participate in the
defense thereof, but the fees and expenses of such separate counsel shall be the
expense of such Indemnified Holder unless (i) the Indemnifying Party has agreed
to pay such fees and expenses, (ii) the Indemnifying Party shall have failed to
promptly assume the defense of such action or proceeding or has failed to employ
counsel reasonably satisfactory to such Indemnified Holder in any such action or
proceeding or (iii) the named parties to any such action or proceeding
(including any impleaded parties) include both such Indemnified Holder and the
Indemnifying Party, and such Indemnified Holder shall have been advised by
counsel that there may be one or more legal defenses available to such
Indemnified Holder that are different from or additional to those available to
the Indemnifying Party or that a conflict may exist between the Indemnified
Holder and the Indemnifying Party.  If such Indemnified Holder notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party as permitted by the provisions of the
preceding sentence, the Indemnifying Party shall not have the right to assume
the defense of such action or proceeding on behalf of such Indemnified Holder.
The foregoing notwithstanding, the Indemnifying Party shall not be liable for
the reasonable fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) at any time for such Indemnified Holder and any
other Indemnified Holders (which firm shall be designated in writing by such
Indemnified Holders) in connection with any one such action or proceeding or
separate but substantially similar or related actions or proceedings in the same
jurisdiction arising out of the same general allegations or circumstances.  The
Indemnifying Party shall not be liable for any settlement of any such action or
proceeding effected without the Indemnifying Party's prior written consent, and
the

                                       15
<PAGE>
 
Indemnifying Party agrees to indemnify and hold harmless any Indemnified  Holder
from and against any loss, damage, liability or expense by reason of any
settlement of any action effected with the written consent of the Indemnifying
Party. No Indemnifying Party shall, without the written consent of the
Indemnified Holder (which consent shall not be unreasonably withheld), effect
the settlement or compromise of, or consent to the entry of any judgment with
respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
Indemnified Holder is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment includes an unconditional release
of the Indemnified Holder from all liability arising out of such action or
claim.

     (d) Contribution.  If the indemnification provided for in this Section 5 is
         ------------                                                           
unavailable to an Indemnified Holder under subsection (a) or (b) above in
respect of any losses, claims, damages or liabilities (or actions in respect
thereof) referred to therein, then each Indemnifying Party shall contribute to
the amount paid or payable by such Indemnified Holder as a result of such
losses, claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and the Indemnified Holder in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations.  The
relative fault of such Indemnifying Party and Indemnified Holder shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by such Indemnifying Party or by
such Indemnified Holder, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The parties hereto agree that it would not be just and equitable if contribution
pursuant to this Section 5(d) were determined by pro rata allocation (even if
the Electing Holders or any underwriters, selling agents or other securities
professionals or all of them were treated as one entity for such purpose) or by
any other method of allocation which does not take account of the equitable
considerations referred to in this Section 5(d).  The amount paid or payable by
an indemnified party as a result of the losses, claims, damages or liabilities
(or actions in respect thereof) referred to above shall be deemed to include any
legal or other fees or expenses reasonably incurred by such Indemnified Party in
connection with investigating or defending any such action or claim.  The
obligations of the Electing Holders and any underwriters, selling agents or
other securities professionals in this Section 5(d) to contribute shall be
several in proportion to the percentage of principal amount of Registrable
Securities registered or underwritten, as the case may be, by them and not
joint.  No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

     (e) Notwithstanding any other provision of this Section 5, in no event will
any (i) Electing Holder be required to undertake liability to any person under
this Section 5 for any amounts in excess of the dollar amount of the proceeds to
be received by such Holder from the sale of such holder's Registrable Securities
(after deducting any fees, discounts and commissions applicable thereto)
pursuant to any Shelf Registration Statement under which such Registrable

                                       16
<PAGE>
 
Securities are to be registered under the Securities Act and (ii) underwriter,
selling agent or other securities professional be required to undertake
liability to any person hereunder for any amounts in excess of the discount,
commission or other compensation payable to such underwriter, selling agent or
other securities professional with respect to the Registrable Securities
underwritten by it and distributed to the public.

     (f) The obligations of the Company and the Trust under this Section 5 shall
be in addition to any liability which the Company and the Trust may otherwise
have to any Indemnified Person and the obligations of any Indemnified Person
under this Section 5 shall be in addition to any liability which such
Indemnified Person may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company, each Administrative
Trustee of the Trust and to each person, if any, who controls the Trust and the
Company within the meaning of the Act. The remedies provided in this Section 5
are not exclusive and shall not limit any rights or remedies which may otherwise
be available to an indemnified party at law or in equity.

     6.   Underwritten Offering.  Any Electing Holder of Registrable Securities
who desires to do so may sell Registrable Securities (in whole or in part) in an
underwritten offering; provided that (i) the Holders of at least a majority in
                       -------------                                          
aggregate principal amount of the outstanding Registrable Securities shall
request such an offering and (ii) at least such aggregate principal amount of
such Registrable Securities shall be included in such offering; and provided
                                                                   ---------
further that the Company shall not be obligated to cooperate with more than one
- -------                                                                        
underwritten offering during the Effectiveness Period.  Upon receipt of such a
request, the Company and the Trust shall provide all Holders of Registrable
Securities written notice of the request, which notice shall inform such Holders
that they have the opportunity to participate in the offering.  In any such
underwritten offering, the investment banker or bankers and manager or managers
that will administer the offering will be selected by, and the underwriting
arrangements with respect thereto (including, subject to clause (ii) above, the
size of the offering) will be approved by the Holders of a majority of the
Registrable Securities to be included in such offering; provided, however, that
such investment bankers and managers and underwriting arrangements must be
reasonably satisfactory to the Company and the Trust.  No Holder may participate
in any underwritten offering contemplated hereby unless (a) such Holder agrees
to sell such Holder's Registrable Securities to be included in the underwritten
offering in accordance with any approved underwriting arrangements, (b) such
Holder completes and executes all reasonable questionnaires, powers of attorney,
indemnities, underwriting agreements, lock-up letters and other documents
required under the terms of such approved underwriting arrangements, and (c) if
such Holder is not then an Electing Holder, such Holder returns a completed and
signed Notice and Questionnaire to the Company and the Trust in accordance with
Section 3(a)(2) hereof (but in no event later than 10 days prior to commencement
of the underwritten offering) and provides to the Trust and the Company, in
writing, any information with respect to such Holder or the Registrable
Securities held by such Holder as is, in the reasonable opinion of counsel to
the Trust or the Company, required under applicable law to enable such Holder to
use such Prospectus for resales of such Registrable Securities, each within a
reasonable amount of time before such underwritten offering.  The Holders
participating in any underwritten

                                       17
<PAGE>
 
offering shall be responsible for any underwriting discounts and commissions and
fees and, subject to Section 4 hereof, expenses of their own counsel.  The
Company and the Trust shall pay all expenses customarily borne by issuers,
including but not limited to filing fees, the fees and disbursements of its
counsel and independent public accountants and any printing expenses incurred in
connection with such underwritten offering.  Notwithstanding the foregoing or
the provisions of Section 3(n) hereof, upon receipt of a request from the
Managing Underwriter or a representative of Holders of a majority of the
Registrable Securities to be included in an underwritten offering to prepare and
file an amendment or supplement to the Shelf Registration Statement and
Prospectus in connection with an underwritten offering, the Company and the
Trust may delay the filing of any such amendment or supplement for up to 90 days
if the Board of Directors of the Company shall have determined in good faith
that the Company has a bona fide business reason for such delay.

     7.   Miscellaneous.

     (a) Other Registration Rights.  The Company may grant registration rights
that would permit any Person that is a third party the right to piggyback on any
Shelf Registration Statement, provided that if the Managing Underwriter of any
underwritten offering conducted pursuant to Section 6 hereof notifies the
Company and the Electing Holders that the total amount of securities which the
Electing Holders and the holders of such piggyback rights intend to include in
any Shelf Registration Statement is so large as to materially threaten the
success of such offering (including the price at which such securities can be
sold), then the amount, number or kind of securities to be offered for the
account of holders of such piggyback rights will be reduced to the extent
necessary to reduce the total amount of securities to be included in such
offering to the amount, number and kind recommended by the Managing Underwriter
prior to any reduction in the amount of Registrable Securities to be included in
such Shelf Registration Statement.

     (b) Amendments and Waivers.  This Agreement, including this Section 7(b),
may be amended, and waivers or consents to departures from the provisions hereof
may be given, only by a written instrument duly executed by the Company and the
Holders of a majority in aggregate principal amount of Registrable Securities
then outstanding.  Each Holder of Registrable Securities outstanding at the time
of any such amendment, waiver or consent or thereafter shall be bound by any
amendment, waiver or consent effected pursuant to this Section 7(b), whether or
not any notice, writing or marking indicating such amendment, waiver or consent
appears on the Registrable Securities or is delivered to such Holder.

     (c) Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail,
telex, telecopier, or air courier guaranteeing overnight delivery:

         (i) if to a Holder, at such address set forth on the record books of
the Company or the Trust, as the case may be;

                                       18
<PAGE>
 
          (ii)   if to the Purchasers, initially at the address set forth in the
Purchase Agreement; and

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

All such notices and communications shall be deemed to have duly given when
received.

     The Purchasers or the Company and the Trust by notice to the other may
designate additional or different addresses for subsequent notices or
communications.

     (d) Parties in Interest.  The parties to this Registration Rights Agreement
intend that all Holders of Registrable Securities shall be entitled to receive
the benefits of this Registration Rights Agreement and that any Electing Holder
shall be bound by the terms and provisions of this Registration Rights Agreement
by reason of such election with respect to the Registrable Securities which are
included in a Shelf Registration Statement.  All the terms and provisions of
this Registration Rights Agreement shall be binding upon, shall inure to the
benefit of and shall be enforceable by the respective successors and assigns of
the parties hereto and any Holder from time to time of the Registrable
Securities to the aforesaid extent.  In the event that any transferee of any
Holder of Registrable Securities shall acquire Registrable Securities, in any
manner, whether by gift, bequest, purchase, operation of law or otherwise, such
transferee shall, without any further writing or action of any kind, be entitled
to receive the benefits of and, if an Electing Holder, be conclusively deemed to
have agreed to be bound by and to perform all of the terms and provisions of
this Registration Rights Agreement to the aforesaid extent.

     (e) Counterparts.  This Registration Rights Agreement may be executed in
any number of counterparts and by the parties hereto in separate counterparts,
each of which when so executed shall be deemed to be an original and all of
which taken together shall constitute one and the same agreement.

     (f) Headings.  The headings in this Registration Rights Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

     (g) Governing Law.  This Registration Rights Agreement shall be governed by
and construed in accordance with the laws of the State of New York, without
giving effect to any provisions relating to conflicts of laws.

     (h) Severability.  In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions hereof shall not be in any way impaired or affected
thereby, it being intended that all of the rights and privileges of the parties
hereto shall be enforceable to the fullest extent permitted by law.

     In answering any item in this Statement of Eligibility which relates to
     matters peculiarly within the knowledge of the obligor and its directors or
     officers, the trustee has relied upon information furnished to it by the
     obligor.

     trustee of all facts on which to base responsive answers to Item 2, the
     answer to said Item are based on incomplete information.

     Item 2, may, however, be considered as correct unless amended by an
     amendment to this Form T-1.

     Pursuant to General Instruction B, the trustee has responded to Items 1, 2
     and 16 of this form since to the best knowledge of the trustee as indicated
     in Item 13, the obligor is not in default under any indenture under which
     the applicant is trustee.
