    Washington Real Estate Investment Trust ("WRIT" or the "Trust") intends to
issue from time to time its (i) unsecured senior or subordinated debt securities
(the "Debt Securities"), (ii) preferred shares of beneficial interest, $.01 par
value per share ("Preferred Shares"), (iii) common shares of beneficial
interest, $.01 par value per share ("Common Shares"), and/or (iv) warrants to
purchase Common Shares ("Common Share Warrants"), having an aggregate initial
public offering price not to exceed $200,000,000 or the equivalent thereof in
one or more foreign currencies or composite currencies, including European
Currency Units, on terms to be determined at the time of sale. The Debt
Securities, the Preferred Shares, the Common Shares and the Common Share
Warrants offered hereby (collectively, the "Offered Securities") may be offered,
separately or as units with other Offered Securities, in separate series or
amounts, at prices and on terms to be determined at the time of sale and to be
set forth in a supplement to this Prospectus (a "Prospectus Supplement.")
 
    The Debt Securities will be direct unsecured obligations of the Trust and
may be either senior Debt Securities ("Senior Securities") or subordinated Debt
Securities ("Subordinated Securities"). The Senior Securities will rank equally
with all other unsecured and unsubordinated indebtedness of the Trust. The
Subordinated Securities will be subordinated to all existing and future Senior
Debt of the Trust, as defined. See "Description of Debt Securities."
 
    The specific terms of the Offered Securities in respect of which this
Prospectus is being delivered will be set forth in the applicable Prospectus
Supplement and will include, where applicable, (i) in the case of Debt
Securities, the specific title, aggregate principal amount, currency,
denominations, maturity, priority, interest rate, time of payment of interest,
terms of redemption at the option of the Trust or repayment at the option of the
holder or for sinking fund payments, terms for conversion into or exchange for
other Offered Securities and the initial public offering price; (ii) in the case
of Preferred Shares, the series designation and the number of shares and the
dividend, liquidation, redemption, conversion, voting and other rights and the
initial public offering price; (iii) in the case of Common Shares, the initial
public offering price; (iv) in the case of Common Share Warrants, the duration,
offering price, exercise price and detachability; and (v) in the case of all
Offered Securities, whether such Offered Securities will be offered separately
or as a unit with other Offered Securities. In addition, such specific terms may
include limitations on direct or beneficial ownership and restrictions on
transfer of the Offered Securities, in each case as may be appropriate to
preserve the status of the Trust as a qualified real estate investment trust
("REIT") under the Internal Revenue Code of 1986, as amended (the "Code").
 
    The applicable Prospectus Supplement will also contain information, where
applicable, about certain United States federal income tax considerations
relating to, and any listing on a securities exchange of, the Offered Securities
covered by such Prospectus Supplement.
 
    The Offered Securities may be offered directly, through agents designated
from time to time by the Trust or to or through underwriters or dealers. If any
agents or underwriters are involved in the sale of any of the Offered
Securities, their names, and any applicable purchase price, fee, commission or
discount arrangement between or among them, will be set forth, or will be
calculable from the information set forth, in an accompanying Prospectus
Supplement. See "Plan of Distribution." No Offered Securities may be sold
without delivery of a Prospectus Supplement describing the method and terms of
the offering of such series of Offered Securities.

                                   THE TRUST
 
    The Trust is an equity real estate investment trust investing in income
producing properties in the Mid-Atlantic area with a principal focus in the
greater Washington-Baltimore region. The Trust owns a diversified portfolio of
49 properties consisting of 16 office buildings, 12 shopping centers, 7
high-rise apartment buildings and 14 industrial distribution properties.
 
    WRIT's principal objective is to increase operating income by investing in
high quality real estate with strong growth potential in prime locations and
aggressively managing these properties with active leasing and capital
improvement programs. The percentage leased at December 31, 1996 for the Trust's
properties was 94% for office buildings, 91% for shopping centers, 98% for
apartment buildings and 97% for industrial distribution properties.
 
    Total debt (all medium term) on December 31, 1996 was $113,000,000, which
represented approximately 17% of the market capitalization of the Trust.
 
    In 1995, the Trust organized WRIT Limited Partnership (the "Partnership") to
assist the Trust in competing for acquisition of properties that meet the
Trust's objectives from sellers who may wish to defer taxation of gain realized
on sale through an exchange of partnership interests.
 
    WRIT's income from operations per share has increased for 31 consecutive
years. WRIT concentrates on increasing its income from operations and funds from
operations to achieve its objective of paying increasing dividends to its
shareholders. Consecutive quarterly dividends have been paid for 35 years, and
the annual dividend paid has increased every year for the last 26 years.
 
    The Trust is a Maryland real estate investment trust, successor to a trust
founded in 1960. The principal offices of the Trust are located at 10400
Connecticut Avenue, Kensington, Maryland 20895, telephone (301) 929-5900 or
(800) 565-9748.
 
                                USE OF PROCEEDS
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
Trust intends to use the net proceeds from the sale of Offered Securities for
general business purposes, including the acquisition and/ or renovation,
expansion or improvement of income-producing properties or the repayment of
indebtedness. It is expected that properties purchased in the future will be of
the same general character as those presently held by the Trust. Pending such
uses, the net proceeds may be invested in short- term income producing
investments such as commercial paper, government securities or money market
funds that invest in government securities.
 
                      RATIOS OF EARNINGS TO FIXED CHARGES
 
    The following table sets forth the Trust's ratios of earnings to fixed
charges for the periods shown:

</TABLE>
 
    The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings consist of income from continuing
operations plus fixed charges. Fixed charges consist of interest expense
(including interest costs capitalized) and the amortization of debt issuance
costs.

relating to the Debt Securities and the Indentures are summaries of the
provisions thereof and do not purport to be complete and are qualified in their
entirety by reference to the Indentures and the Debt Securities. All Section
references herein are to sections of the Indentures, and capitalized terms used
but not defined herein shall have the respective meanings set forth in the
Indentures and the Debt Securities.
 
TERMS
 
    The Debt Securities will be direct, unsecured obligations of the Trust. The
indebtedness represented by the Senior Securities will rank equally with all
other unsecured and unsubordinated indebtedness of the Trust. The indebtedness
represented by the Subordinated Securities will be subordinated in right of
payment to the prior payment in full of the Senior Debt of the Trust, as
described under "Subordination." Each Indenture provides that the Debt
Securities may be issued without limit as to aggregate principal amount, in one
or more series, in each case as established from time to time in or pursuant to
authority granted by a resolution of the Board of Trustees of the Trust or as
established in one or more indentures supplemental to such Indenture. Debt
Securities may be issued with terms different from those of Debt Securities
previously issued. All Debt Securities of one series need not be issued at the
same time and, unless otherwise provided, a series may be reopened, without the
consent of the holders of the Debt Securities of such series, for issuances of
additional Debt Securities of such series (Section 301 of each Indenture).
 
    Each Indenture provides that there may be more than one Indenture Trustee
thereunder, each with respect to one or more series of Debt Securities. Any
Indenture Trustee under either Indenture may resign or be removed with respect
to one or more series of Debt Securities, and a successor Indenture Trustee may
be appointed to act with respect to such series (Section 608 of each Indenture).
In the event that two or more persons are acting as Indenture Trustee with
respect to different series of Debt Securities, each such Indenture Trustee
shall be an Indenture Trustee of a trust under the applicable Indenture separate
and apart from the trust administered by any other Indenture Trustee (Section
609 of each Indenture), and, except as otherwise indicated herein, any action
described herein to be taken by an Indenture Trustee may be taken by each such
Indenture Trustee with respect to, and only with respect to, the one or more
series of Debt Securities for which it is Indenture Trustee under the applicable
Indenture.

    Except as set forth below under "--Certain Covenants" and as may be set
forth in any Prospectus Supplement, the Indentures will not contain any

that would afford holders of Debt Securities protection in the event of a highly
leveraged or similar transaction involving the Trust or in the event of a change
of control. Reference is made to the applicable Prospectus Supplement for
information with respect to any deletions from, modifications of, or additions
to the events of default or covenants of the Trust that are described below,
including any addition of a covenant or other provision providing event risk or
similar protection.
 
DENOMINATIONS, INTEREST, REGISTRATION AND TRANSFER
 
    Unless otherwise described in the applicable Prospectus Supplement, the Debt
Securities of any series issued in registered form will be issuable in
denominations of $1,000 and integral multiples thereof. Unless otherwise
specified in the applicable Prospectus Supplement, the Debt Securities of any
series issued in bearer form will be issuable in denominations of $5,000.
(Section 302 of each Indenture).
 
    Unless otherwise specified in the applicable Prospectus Supplement, the
principal of (and premium, if any) and interest on any series of Senior
Securities will be payable at the corporate trust office of the Senior Indenture
Trustee, which initially shall be c/o First Chicago Trust Company of New York,
14 Wall Street, Eighth Floor, New York, New York 10005 and the principal of (and
premium, if any) and interest
 
                                       7
<PAGE>
on any series of Subordinated Securities will be payable at the corporate trust
office of the Subordinated Indenture Trustee; provided that, at the option of
the Trust, payment of interest on any series of Debt Securities may be made by
check mailed to the address of the Person entitled thereto as it appears in the
applicable register for such Debt Securities or by wire transfer of funds to
such person at an account maintained within the United States (Sections 301, 307
and 1002 of each Indenture).
 
    Any interest not punctually paid or duly provided for on any interest
payment date with respect to a Debt Security ("Defaulted Interest") will
forthwith cease to be payable to the holder on the applicable Regular Record
Date and may either be paid to the Person in whose name such Security is
registered at the close of business on a special record date (the "Special
Record Date") for the payment of such Defaulted Interest to be fixed by the
Indenture Trustee, notice whereof shall be given to the holder of such Debt
Security not less than 10 days prior to such Special Record Date, or may be paid
at any time in any other lawful manner, all as more completely described in the
applicable Indenture (Section 307 of each Indenture).
 
    Subject to certain limitations imposed upon Debt Securities issued in
book-entry form, the Debt Securities of any series will be exchangeable for
other Debt Securities of the same series and of a like aggregate principal
amount and tenor of different authorized denominations upon surrender of such
Debt Securities at the corporate trust office of the applicable Indenture
Trustee referred to above. In addition, subject to certain limitations imposed
upon Debt Securities issued in book-entry form, the Debt Securities of any
series may be surrendered for conversion, registration of transfer or exchange
thereof at the corporate trust office of the applicable Indenture Trustee. Every
Debt Security surrendered for conversion, registration of transfer or exchange
must be duly endorsed or accompanied by a written instrument of transfer. No
service charge will be made for any registration of transfer or exchange of any
Debt Securities, but the Trust may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith (Section
305 of each Indenture). If the applicable Prospectus Supplement refers to any
transfer agent (in addition to the applicable Indenture Trustee) initially
designated by the Trust with respect to any series of Debt Securities, the Trust
may at any time rescind the designation of any such transfer agent or approve a
change in the location through which any such transfer agent acts, except that
the Trust will be required to maintain a transfer agent in each place of payment
for such series. The Trust may at any time designate additional transfer agents
with respect to any series of Debt Securities (Section 1002 of each Indenture).
 
    Neither the Trust nor either Indenture Trustee shall be required to (i)
issue, register the transfer of or exchange Debt Securities of any series during
a period beginning at the opening of business 15 days before any selection of
Debt Securities of that series to be redeemed and ending at the close of
business on the day of mailing of the relevant notice of redemption; (ii)
register the transfer of or exchange any Debt Security, or portion thereof,
called for redemption, except the unredeemed portion of any Debt Security being
redeemed in part; or (iii) issue, register the transfer of or exchange any Debt
Security that has been surrendered for repayment at the option of the holder,
except the portion, if any, of such Debt Security not to be so repaid (Section
305 of each Indenture).
 
MERGER, CONSOLIDATION OR SALE
 
    The Trust will be permitted to consolidate with, or sell, lease or convey
all or substantially all of its assets to, or merge with or into, any other
entity provided that (a) either the Trust shall be the continuing entity, or the
successor entity (if other than the Trust) formed by or resulting from any such
consolidation or merger or which shall have received the transfer of such assets
shall expressly assume payment of the principal of (and premium, if any) and
interest on all of the Debt Securities and the due and punctual performance and
observance of all of the covenants and conditions contained in each Indenture;
(b) immediately after giving effect to such transaction and treating any
indebtedness that becomes an obligation of the Trust or any Subsidiary as a
result thereof as having been incurred by the Trust or such Subsidiary at the
time of such transaction, no Event of Default under an Indenture, and no event
which,
 
                                       8
<PAGE>
after notice or the lapse of time, or both, would become such an Event of
Default, shall have occurred and be continuing; and (c) an officer's certificate
and legal opinion covering such conditions shall be delivered to the Indenture
Trustee (Sections 801 and 803 of each Indenture).
 
CERTAIN COVENANTS
 
    SENIOR INDENTURE LIMITATIONS ON INCURRENCE OF DEBT.  The Senior Indenture
provides that the Trust will not, and will not permit any Subsidiary to, incur
any Debt (as defined below) if, immediately after giving effect to the
incurrence of such Debt and the application of the proceeds thereof, the
aggregate principal amount of all outstanding Debt of the Trust and its
Subsidiaries on a consolidated basis determined in accordance with generally
accepted accounting principles is greater than 60% of the sum of (without
duplication) (i) the Trust's Total Assets as of the end of the calendar quarter
covered in the Trust's Annual Report on Form 10-K or Quarterly Report on Form
10-Q, as the case may be, most recently filed with the Commission (or, if such
filing is not permitted under the Exchange Act, with the Indenture Trustee)
prior to the incurrence of such additional Debt and (ii) any increase in the
Trust's Total Assets since the end of such quarter including, without
limitation, any increase in Total Assets resulting from the incurrence of such
additional Debt (such increase together with the Trust's Total Assets being
referred to as "Adjusted Total Assets") (Section 1011 of the Senior Indenture).
 
    In addition to the foregoing limitation on the incurrence of Debt, the
Senior Indenture provides that the Trust will not, and will not permit any
Subsidiary to, incur any Debt secured by any mortgage, lien, charge, pledge,
encumbrance or security interest of any kind upon any of the property of the
Trust or any Subsidiary ("Secured Debt"), whether owned at the date of the
Senior Indenture or thereafter acquired, if, immediately after giving effect to
the incurrence of such additional Secured Debt and the application of the
proceeds thereof, the aggregate principal amount of all outstanding Secured Debt
of the Trust and its Subsidiaries on a consolidated basis is greater than 40% of
the Trust's Adjusted Total Assets (Section 1011 of the Senior Indenture).
 
    In addition to the foregoing limitations on the incurrence of Debt, the
Senior Indenture provides that the Trust will not, and will not permit any
Subsidiary to, incur any Debt if the ratio of Consolidated Income Available for
Debt Service (as defined below) to the Annual Service Charge (as defined below)
for the four consecutive fiscal quarters most recently ended prior to the date
on which such additional Debt is to be incurred shall have been less than 1.5 to
1.0, on a pro forma basis after giving effect thereto and to the application of
the proceeds therefrom, and calculated on the assumption that (i) such Debt and
any other Debt incurred by the Trust and its Subsidiaries since the first day of
such four-quarter period and the application of the proceeds therefrom,
including to refinance other Debt, had occurred at the beginning of such period;
(ii) the repayment or retirement of any other Debt by the Trust and its
Subsidiaries since the first day of such four-quarter period had been incurred,
repaid or retired at the beginning of such period (except that, in making such
computation, the amount of Debt under any revolving credit facility shall be
computed based upon the average daily balance of such Debt during such period);
(iii) in the case of Acquired Debt (as defined below) or Debt incurred in
connection with any acquisition since the first day of such four-quarter period,
the related acquisition had occurred as of the first day of such period with the
appropriate adjustments with respect to such acquisition being included in such
pro forma calculation; and (iv) in the case of any acquisition or disposition by
the Trust or its Subsidiaries of any asset or group of assets since the first
day of such four-quarter period, whether by merger, stock purchase or sale, or
asset purchase or sale, such acquisition or disposition or any related repayment
of Debt had occurred as of the first day of such period with the appropriate
adjustments with respect to such acquisition or disposition being included in
such pro forma calculation (Section 1011 of the Senior Indenture).
 
    For purposes of the foregoing provisions regarding the limitation on the
incurrence of Debt, Debt shall be deemed to be "incurred" by the Trust or a
Subsidiary whenever the Trust or such Subsidiary shall create, assume, guarantee
or otherwise become liable in respect thereof.
 
                                       9

    MAINTENANCE OF TOTAL UNENCUMBERED ASSETS.  The Senior Indenture also
provides that the Trust is required to maintain Total Unencumbered Assets (as
defined below) of not less than 150% of the aggregate outstanding principal
amount of the Unsecured Debt (as defined below) of the Trust (Section 1012 of
the Senior Indenture).

consolidated balance sheet in accordance with generally accepted accounting

against loss or damage at least equal to their then full insurable value with
insurers of recognized responsibility and, if described in the applicable
Prospectus Supplement, having a specified rating from a recognized insurance
rating service (Section 1006 of each Indenture).
 
    PAYMENT OF TAXES AND OTHER CLAIMS.  The Trust will be required to pay or
discharge or cause to be paid or discharged, before the same shall become
delinquent, (i) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Trust or any Subsidiary, and (ii) all lawful claims for labor, materials and
supplies, which, if unpaid, might by law become a material lien upon the
property of the Trust or any Subsidiary; PROVIDED, HOWEVER, that the Trust 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 (Section 1007 of each Indenture).
 
    PROVISION OF FINANCIAL INFORMATION.  Whether or not the Trust is subject to
Section 13 or 15(d) of the Exchange Act, the Trust will be required, within 15
days of each of the respective dates by which the Trust would have been required
to file annual reports, quarterly reports and other documents with the
Commission if the Trust were so subject, to (i) transmit by mail to all holders
of Debt Securities, as their names and addresses appear in the applicable
register for such Debt Securities, without cost to such holders, copies of the
annual reports, quarterly reports and other documents that the Trust would have
been required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act if the Trust were subject to such sections, (ii) file with the
applicable Indenture Trustee copies of the annual reports, quarterly reports and
other documents that the Trust would have been required to file with the
Commission pursuant to Section 13 or 15(d) of the Exchange Act if the Trust were
subject to such Sections, and (iii) promptly upon written request and payment of
the reasonable cost of duplication and delivery, supply copies of such documents
to any prospective holder (Section 1008 of each Indenture).
 
    ADDITIONAL COVENANTS.  Any additional covenants of the Trust with respect to
any series of Debt Securities will be set forth in the Prospectus Supplement
relating thereto.
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
    Each Indenture provides that the following events are "Events of Default"
with respect to any series of Debt Securities issued thereunder: (a) default for
30 days in the payment of any installment of interest or Additional Amounts
payable on any Debt Security of such series; (b) default in the payment of
principal of (or premium, if any, on) any Debt Security of such series at its
maturity; (c) default in making any sinking fund payment as required for any
Debt Security of such series; (d) default in the performance or breach of any
other covenant or warranty of the Trust contained in the Indenture (other than a
covenant added to the Indenture solely for the benefit of a series of Debt
Securities issued thereunder other than such series), continued for 60 days
after written notice as provided in the Indenture; (e) a default under any bond,
debenture, note or other evidence of indebtedness for money borrowed by the
Trust (including obligations under leases required to be capitalized on the
balance sheet of the lessee under generally accepted accounting principles but
not including any indebtedness or obligations for which recourse is limited to
property purchased) in an aggregate principal amount in excess of $5,000,000 or
under any mortgage, indenture or instrument under which there may be issued or
by which there may be secured or evidenced any indebtedness for money borrowed
by the Trust (including such leases, but not including such indebtedness or
obligations for which recourse is limited to property purchased) in an aggregate
principal amount in excess of $5,000,000, whether such indebtedness now exists
or shall hereafter be created which default shall have resulted in such
indebtedness becoming or being declared due and payable prior to the date on
which it would otherwise have become due and payable or such obligations being
accelerated, without such acceleration having been rescinded or annulled; (f)
certain events of bankruptcy, insolvency or reorganization, or court appointment
of a receiver, liquidator or trustee of the Trust or any Significant
 
                                       12
<PAGE>
Subsidiary of the Trust; and (g) any other event of default provided with
respect to a particular series of Debt Securities (Section 501 of each
Indenture). The term "Significant Subsidiary" means each significant subsidiary
(as defined in Regulation S-X promulgated under the Securities Act) of the
Trust.
 
    If an Event of Default under either Indenture with respect to Debt
Securities of any series at the time outstanding occurs and is continuing, then
in every such case the Indenture Trustee or the holders of not less than 25% in
principal amount of the outstanding Securities of that series will have the
right to declare the principal amount (or, if the Debt Securities of that series
are Original Issue Discount Securities or Indexed Securities, such portion of
the principal amount as may be specified in the terms thereof) of, and premium,
if any, on all of the Debt Securities of that series to be due and payable
immediately by written notice thereof to the Trust (and to the Indenture Trustee
if given by the holders). However, at any time after such a declaration of
acceleration with respect to Debt Securities of such series (or of all Debt
Securities then outstanding under the applicable Indenture, as the case may be)
has been made, but before a judgment or decree for payment of the money due has
been obtained by the Indenture Trustee, the holders of not less than a majority
in principal amount of outstanding Debt Securities of such series (or of all
Debt Securities then outstanding under the applicable Indenture, as the case may
be) may rescind and annul such declaration and its consequences if (a) the Trust
shall have deposited with the applicable Indenture Trustee all required payments
of the principal of (and premium, if any) and interest, and any Additional
Amounts, on the Debt Securities of such series (or of all Debt Securities then
outstanding under the applicable Indenture, as the case may be), plus certain
fees, expenses, disbursements and advances of such Indenture Trustee and (b) all
Events of Default, other than the non-payment of accelerated principal (or
specified portion thereof and the premium, if any) or interest, with respect to
Debt Securities of such series (or of all Debt Securities then outstanding under
the applicable Indenture, as the case may be) have been cured or waived as
provided in the applicable Indenture (Section 502 of each Indenture). Each
Indenture also provides that the holders of not less than a majority in
principal amount of the outstanding Debt Securities of any series (or of all
Debt Securities then outstanding under the applicable Indenture, as the case may
be) may waive any past default with respect to such series and its consequences,
except a default (x) in the payment of the principal of (or premium, if any) or
interest or Additional Amounts payable on any Debt Security of such series or
(y) in respect of a covenant or provision contained in the applicable Indenture
that cannot be modified or amended without the consent of the holder of each
outstanding Debt Security affected thereby (Section 513 of each Indenture).
 
    Each Indenture Trustee will be required to give notice to the holders of
Debt Securities within 90 days of a default under the applicable Indenture
unless such default shall have been cured or waived; PROVIDED, HOWEVER, that
such Indenture Trustee may withhold notice to the holders of any series of Debt
Securities of any default with respect to such series (except a default in the
payment of the principal of (or premium, if any) or interest or Additional
Amounts payable on any Debt Security of such series or in the payment of any
sinking fund installment in respect of any Security of such series) if specified
responsible officers of such Indenture Trustee consider such withholding to be
in the interest of such holders (Section 601 of each Indenture).
 
    Each Indenture provides that no holders of Debt Securities of any series may
institute any proceedings, judicial or otherwise, with respect to such Indenture
or for any remedy thereunder, except in the cases of failure of the Indenture
Trustee, for 60 days, to act after it has received a written request to
institute proceedings in respect of an event of default from the holders of not
less than 25% in principal amount of the outstanding Debt Securities of such
series, as well as an offer of indemnity reasonably satisfactory to it (Section
507 of each Indenture). This provision will not prevent, however, any holder of
Debt Securities from instituting suit for the enforcement of payment of the
principal of (and premium, if any), interest on and Additional Amounts payable
with respect to, such Debt Securities at the respective due dates thereof.
 
    Subject to provisions in each Indenture relating to its duties in case of
default, each Indenture Trustee will not be under any obligation to exercise any
of its rights or powers under the applicable Indenture at the request or
direction of any holders of any series of Debt Securities then outstanding under
such
 
                                       13
<PAGE>
Indenture, unless such holders shall have offered to the Indenture Trustee
thereunder reasonable security or indemnity (Section 602 of each Indenture). The
holders of not less than a majority in principal amount of the outstanding Debt
Securities of any series (or of all Debt Securities then outstanding under the
applicable Indenture, as the case may be) shall have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the Indenture Trustee, or of exercising any trust or power conferred upon such
Indenture Trustee. However, an Indenture Trustee may refuse to follow any
direction which is in conflict with any law or the Indenture, which may involve
the Indenture Trustee in personal liability or which may be unduly prejudicial
to the holders of Debt Securities of such series not joining therein (Section
512 of each Indenture).
 
    Within 120 days after the close of each fiscal year, the Trust will be
required to deliver to each Indenture Trustee a certificate, signed by one of
several specified officers of the Trust, stating whether or not such officer has
knowledge of any default under the applicable Indenture and, if so, specifying
each such default and the nature and status thereof (Section 1009 of each
Indenture).
 
MODIFICATION OF THE INDENTURES
 
    Modifications and amendments of either Indenture will be permitted to be
made only with the consent of the holders of not less than a majority in
principal amount of all outstanding Debt Securities issued under each Indenture
which are affected by such modification or amendment; PROVIDED, HOWEVER, that no
such modification or amendment may, without the consent of the holder of each
such Debt Security affected thereby, (a) change the stated maturity of the
principal of (or premium, if any) , or any installment of principal of or
interest payable on, any such Debt Security; (b) reduce the principal amount of,
or the rate or amount of interest on, or any premium payable on redemption of,
or Additional Amounts payable with respect to, any such Debt Security, or reduce
the amount of principal of an Original Issue Discount Security that would be due
and payable upon declaration of acceleration of the maturity thereof or would be
provable in bankruptcy, or adversely affect any right of repayment of the holder
of any such Debt Security; (c) change the place of payment, or the coin or
currency, for payment of principal of (and premium, if any), or interest on, or
any Additional Amounts payable with respect to, any such Debt Security; (d)
impair the right to institute suit for the enforcement of any payment on or with
respect to any such Debt Security; (e) reduce the above-stated percentage of
outstanding Debt Securities of any series necessary to modify or amend the
applicable Indenture, to waive compliance with certain provisions thereof or
certain defaults and consequences thereunder or to reduce the quorum or voting
requirements set forth in the Indenture; or (f) modify any of the foregoing
provisions or any of the provisions relating to the waiver of certain past
defaults or certain covenants, except to increase the required percentage to
effect such action or to provide that certain other provisions may not be
modified or waived without the consent of the holder of such Debt Security
(Section 902 of each Indenture).
 
    The holders of not less than a majority in principal amount of outstanding
Debt Securities issued under either Indenture will have the right to waive
compliance by the Trust with certain covenants in such Indenture (Section 1013
of each Indenture).
 
    Modifications and amendments of each Indenture will be permitted to be made
by the Trust and the applicable Indenture Trustee thereunder without the consent
of any holder of Debt Securities for any of the following purposes: (i) to
evidence the succession of another person to the Trust as obligor under the
applicable Indenture; (ii) to add to the covenants of the Trust for the benefit
of the holders of all or any series of Debt Securities or to surrender any right
or power conferred upon the Trust in the applicable Indenture; (iii) to add
events of default for the benefit of the holders of all or any series of Debt
Securities; (iv) to add or change any provisions of the applicable Indenture to
facilitate the issuance of, or to liberalize certain terms of, Debt Securities
in bearer form, or to permit or facilitate the issuance of Debt Securities in
uncertificated form, PROVIDED that such action shall not adversely affect the
interests of the holders of the Debt Securities of any series in any material
aspect; (v) to change or eliminate any provisions of the applicable Indenture,
PROVIDED that any such change or elimination shall become effective only when
there
 
                                       14
<PAGE>
are no Debt Securities outstanding of any series created prior thereto which are
entitled to the benefit of such provision; (vi) to secure the Debt Securities;
(vii) to establish the form or terms of Debt Securities of any series; (viii) to
provide for the acceptance of appointment by a successor Indenture Trustee or
facilitate the administration of the trusts under the applicable Indenture by
more than one Indenture Trustee; (ix) to cure any ambiguity, defect or
inconsistency in the applicable Indenture, PROVIDED that such action shall not
adversely affect the interests of holders of Debt Securities of any series
issued under such Indenture in any material respect; or (x) to supplement any of
the provisions of such Indenture to the extent necessary to permit or facilitate
defeasance and discharge of any series of such Debt Securities, PROVIDED that
such action shall not adversely affect the interests of the holders of the Debt
Securities of any series in any material respect (Section 901 of each
Indenture).
 
    Each Indenture provides that in determining whether the holders of the
requisite principal amount of outstanding Debt Securities of a series have given
any request, demand, authorization, direction, notice, consent or waiver
thereunder or whether a quorum is present at a meeting of holders of Debt
Securities, (i) the principal amount of an Original Issue Discount Security that
shall be deemed to be outstanding shall be the amount of the principal thereof
that would be due and payable as of the date of such determination upon
declaration of acceleration of the maturity thereof, (ii) the principal amount
of any Debt Security denominated in a foreign currency that shall be deemed
outstanding shall be the U.S. dollar equivalent, determined on the issue date
for such Debt Security, of the principal amount (or, in the case of Original
Issue Discount Security, the U.S. dollar equivalent on the issue date of such
Debt Security of the amount determined as provided in (i) above), (iii) the
principal amount of an Indexed Security that shall be deemed outstanding shall
be the principal face amount of such Indexed Security at original issuance,
unless otherwise provided with respect to such indexed security pursuant to
Section 301 of the Indenture, and (iv) Debt Securities owned by the Trust or any
other obligor upon the Debt Securities or any affiliate of the Trust or of such
other obligor shall be disregarded (Section 101 of each Indenture).
 
    Each Indenture contains provisions for convening meetings of the holders of
Debt Securities of a series (Section 1501 of each Indenture). A meeting will be
permitted to be called at any time by the applicable Indenture Trustee, and
also, upon request, by the Trust or the holders of at least 10% in principal
amount of the outstanding Debt Securities of such series, in any such case upon
notice given as provided in the applicable Indenture (Section 1502 of each
Indenture). Except for any consent that must be given by the holder of each Debt
Security affected by certain modifications and amendments of the applicable
Indenture, any resolution presented at a meeting or adjourned meeting duly
reconvened at which a quorum is present may be adopted by the affirmative vote
of the holders of a majority in principal amount of the outstanding Debt
Securities of that series; PROVIDED, HOWEVER, that, except as referred to above,
any resolution with respect to any request, demand, authorization, direction,
notice, consent, waiver or other action that may be made, given or taken by the
holders of a specified percentage, which is less than a majority, in principal
amount of the outstanding Debt Securities of a series may be adopted at a
meeting or adjourned meeting or adjourned meeting duly reconvened at which a
quorum is present by the affirmative vote of the holders of such specified
percentage in principal amount of the outstanding Debt Securities of that
series. Any resolution passed or decision taken at any meeting of holders of
Debt Securities of any series duly held in accordance with the applicable
Indenture will be binding on all holders of Debt Securities of that series. The
quorum at any meeting called to adopt a resolution, and at any reconvened
meeting, will be persons holding or representing a majority in principal amount
of the outstanding Debt Securities of a series; PROVIDED, HOWEVER, that if any
action is to be taken at such meeting with respect to a consent or waiver which
may be given by the holders of not less than a specified percentage in principal
amount of the outstanding Debt Securities of a series, the persons holding or
representing such specified percentage in principal amount of the outstanding
Debt Securities of such series will constitute a quorum (Section 1504 of each
Indenture).
 
    Notwithstanding the foregoing provisions, each Indenture provides that if
any action is to be taken at a meeting of holders of Debt Securities of any
series with respect to any request, demand, authorization,
 
                                       15
<PAGE>
direction, notice, consent, waiver and other action that the Indenture expressly
provides may be made, given or taken by the holders of a specified percentage in
principal amount of all outstanding Debt Securities affected thereby, or of the
holders of such series and one or more additional series: (i) there shall be no
minimum quorum requirement for such meeting, and (ii) the principal amount of
the outstanding Debt Securities of such series that vote in favor of such
request, demand, authorization, direction, notice, consent, waiver or other
action shall be taken into account in determining whether such request, demand,
authorization, direction, notice, consent, waiver or other action has been made,
given or taken under the Indenture (Section 1504 of each Indenture).
 
SUBORDINATION
 
    Upon any distribution to creditors of the Trust in a liquidation,
dissolution or reorganization, the payment of the principal of and interest on
the Subordinated Securities will be subordinated to the extent provided in the
Subordinated Indenture in right of payment to the prior payment in full of all
Senior Debt (Sections 1601 and 1602 of the Subordinated Indenture), but the
obligation of the Trust to make payment of the principal and interest on the
Subordinated Securities will not otherwise be affected (Section 1608 of the
Subordinated Indenture). No payment of principal or interest may be made on the
Subordinated Securities at any time if a default on Senior Debt exists that
permits the holders of such Senior Debt to accelerate its maturity and the
default is the subject of judicial proceedings or the Trust receives notice of
the default (Section 1603 of the Subordinated Indenture). After all Senior Debt
is paid in full and until the Subordinated Securities are paid in full, holders
will be subrogated to the rights of holders of Senior Debt to the extent that
distributions otherwise payable to holders have been applied to the payment of
Senior Debt (Section 1607 of the Subordinated Indenture). By reason of such
subordination, in the event of a distribution of assets upon insolvency, certain
general creditors of the Trust may recover more, ratably, than holders of the
Subordinated Securities.
 
    Senior Debt is defined in the Subordinated Indenture as the principal of and
interest on, or substantially similar payments to be made by the Trust in
respect of, the following, whether outstanding at the date of execution of the
Subordinated Indenture or thereafter incurred, created or assumed: (a)
indebtedness of the Trust for money borrowed or represented by purchase-money
obligations, (b) indebtedness of the Trust evidenced by notes, debentures, or
bonds, or other securities issued under the provisions of an indenture, fiscal
agency agreement or other instrument, (c) obligations of the Trust as lessee
under leases of property either made as part of any sale and leaseback
transaction to which the Trust is a party or otherwise, (d) indebtedness of
partnerships and joint ventures that is included in the consolidated financial
statements of the Trust, (e) indebtedness, obligations and liabilities of others
in respect of which the Trust is liable contingently or otherwise to pay or
advance money or property or as guarantor, endorser or otherwise or which the
Trust has agreed to purchase or otherwise acquire and (f) any binding commitment
of the Trust to fund any real estate investment or to fund any investment in any
entity making such real estate investment, in each case other than (1) any such
indebtedness, obligation or liability referred to in clauses (a) through (f)
above as to which, in the instrument creating or evidencing the same pursuant to
which the same is outstanding, it is provided that such indebtedness, obligation
or liability is not superior in right of payment to the Subordinated Securities
or ranks pari passu with the Subordinated Securities, (2) any such indebtedness,
obligation or liability which is subordinated to indebtedness of the Trust, to
substantially the same extent as or to a greater extent than the Subordinated
Securities are subordinated and (3) the Subordinated Securities (Section 101 of
the Subordinated Indenture). At December 31, 1996, Senior Debt aggregated
approximately $113 million. There are no restrictions in the Subordinated
Indenture upon the creation of additional Senior Debt. However, the Senior
Indenture contains limitations on incurrence of indebtedness by the Trust.
"See--Certain Covenants--Senior Indenture Limitations on Incurrence of Debt."

<PAGE>
DISCHARGE, DEFEASANCE AND COVENANT DEFEASANCE
 
    Under each Indenture, the Trust may discharge certain obligations to holders
of any series of Debt Securities issued thereunder that have not already been
delivered to the applicable Indenture Trustee for cancellation and that either
have become due and payable or will become due and payable within one year (or
scheduled for redemption within one year) by irrevocably depositing with the
applicable Indenture Trustee, in trust, funds in such currency or currencies,
currency unit or units or composite currency or currency in which such Debt
Securities are payable in an amount sufficient to pay the entire indebtedness on
such Debt Securities in respect of principal (and premium, if any) and interest
and any Additional Amounts payable to the date of such deposit (if such Debt
Securities have become due and payable) or to the stated maturity or redemption
date, as the case may be (Section 401 of each Indenture).
 
    Each Indenture provides that, if the provisions of Article Fourteen thereof
are made applicable to the Debt Securities of or within any series pursuant to
Section 301 of such Indenture, the Trust may elect either (a) to defease and be
discharged from any and all obligations with respect to such Debt Securities
(except for the obligation to pay Additional Amounts, if any, upon the
occurrence of certain events of tax, assessment or governmental charge with
respect to payments on such Debt Securities and the obligations to register the
transfer or exchange of such Debt Securities, to replace temporary or mutilated,
destroyed, lost or stolen Debt Securities, to maintain an office or agency in
respect of such Debt Securities and to hold moneys for payment in trust)
("defeasance") (Section 1402 of each Indenture) or (b) to be released from its
obligations with respect to such Debt Securities under Sections 1004 to 1008,
inclusive, and Sections 1011 and 1012 under such Indenture (being the
restrictions described under "--Certain Covenants") or, if provided pursuant to
such Indenture, its obligations with respect to any other covenant, and any
omission to comply with such obligations shall not constitute an event of
default with respect to such Debt Securities ("covenant defeasance") (Section
1403 of each Indenture), in either case upon the irrevocable deposit by the
Trust with the applicable Indenture Trustee, in trust, of an amount, in such
currency or currencies, currency unit or units or composite currency or
currencies in which such Debt Securities are payable at stated maturity, or
Government Obligations (as defined below), or both, applicable to such Debt
Securities which through the scheduled payment of principal and interest in
accordance with their terms will provide money in an amount sufficient to pay
the principal of (and premium, if any) and interest on such Debt Securities, and
any mandatory sinking fund or analogous payments thereon, on the scheduled due
dates therefor (Section 1404 of each Indenture).
 
    Such a trust will only be permitted to be established if, among other
things, the Trust has delivered to the applicable Indenture Trustee an opinion
of counsel (as specified in each Indenture) to the effect that the holders of
such Debt Securities will not recognize income, gain or loss for U.S. federal
income tax purposes as a result of such defeasance or covenant defeasance and
will be subject to U.S. federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such defeasance or
covenant defeasance had not occurred, and such opinion of counsel, in the case
of defeasance, will be required to refer to and be based upon a ruling of the
Internal Revenue Service or a change in applicable United States federal income
tax law occurring after the date of such Indenture (Section 1404 of each
Indenture).
 
    "Government Obligations" means securities which are (i) direct obligations
of the United States of America or the government which issued the foreign
currency in which the Debt Securities of a particular series are payable for the
payment of which its full faith and credit is pledged or (ii) obligations of a
person controlled or supervised by and acting as an agency or instrumentality of
the United States of America or the government which issued the foreign currency
in which the Debt Securities of a particular series are payable, the payment of
which is unconditionally guaranteed as a full faith and credit obligation by the
United States of America or such other government, which, in either case, are
not callable or redeemable at the option of the issuer thereof, and shall also
include a depository receipt issued by a bank or trust company as custodian with
respect to any such Government Obligation or a specific payment of interest on
or principal of any such Government Obligation held by such custodian for the
account of the holder of a
 
                                       17
<PAGE>
depository receipt, PROVIDED that (except as required by law) such custodian is
not authorized to make any deduction from the amount payable to the holder of
such depository receipt from any amount receiving by the custodian in respect of
the Government Obligation or the specific payment of interest on or principal of
the Government Obligation evidenced by such depository receipt (Section 101 of
each Indenture).
 
    Unless otherwise provided in the applicable Prospectus Supplement, if after
the Trust has deposited funds and/or Government Obligations to effect defeasance
or covenant defeasance with respect to Debt Securities of any series, (a) the
holder of a Debt Security of such series is entitled to, and does, elect
pursuant to Section 301 of either Indenture or the terms of such Debt Security
to receive payment in a currency, currency unit or composite currency other than
that in which such deposit has been made in respect of such Debt Security, or
(b) a Conversion Event (as defined below) occurs in respect of the currency,
currency unit or composite currency in which such deposit has been made, the
indebtedness represented by such Debt Security shall be deemed to have been, and
will be, fully discharged and satisfied through the payment of the principal of
(and premium, if any) and interest on such Debt Security as they become due out
of the proceeds yielded by converting the amount so deposited in respect of such
Security into the currency, currency unit or composite currency in which such
Debt Security becomes payable as a result of such election or such cessation of
usage based on the applicable market exchange rate (Section 1405 of each
Indenture). "Conversion Event" means the cessation of use of (i) a currency,
currency unit or composite currency both by the government of the country which
issued such currency and for the settlement of transactions by a central bank or
other public institutions of or within the international banking community, (ii)
the ECU both within the European Monetary System and for the settlement of
transactions by public institutions of or within the European Communities or
(iii) any currency unit or composite currency other than the ECU for the
purposes for which it was established. Unless otherwise provided in the
applicable Prospectus Supplement, all payments of principal of (and premium, if
any) and interest on any Debt Security that is payable in a foreign currency
that ceases to be used by its government of issuance shall be in U.S. dollars
(Section 101 of each Indenture).
 
    In the event the Trust effects covenant defeasance with respect to any Debt
Securities and such Debt Securities are declared due and payable because of the
occurrence of any Event of Default other than the Event of Default described in
clause (d) under "Events of Default, Notice and Waiver" with respect to Sections
1004 to 1008, inclusive, and Sections 1011 and 1012 of either Indenture (which
sections would no longer be applicable to such Debt Securities) or described in
clause (g) under "Events of Default, Notice and Waiver" with respect to any
other covenant as to which there has been covenant defeasance, the amount in
such currency, currency unit or composite currency in which such Debt Securities
are payable, and Government Obligations on deposit with the applicable Indenture
Trustee, will be sufficient to pay amounts due on such Debt Securities at the
time of their stated maturity but may not be sufficient to pay amounts due on
such Debt Securities at the time of the acceleration resulting from such Event
of Default. However, the Trust would remain liable to make payment of such
amounts due at the time of acceleration.
 
    The applicable Prospectus Supplement may further describe the provisions, if
any, permitting such defeasance or covenant defeasance, including any
modifications to the provisions described above, with respect to the Debt
Securities of or within a particular series.
 
CONVERSION RIGHTS
 
    The terms and conditions, if any, upon which the Debt Securities are
convertible into Common Shares or Preferred Shares will be set forth in the
applicable Prospectus Supplement relating thereto. Such terms will include
whether such Debt Securities are convertible into Common Shares or Preferred
Shares, the conversion price (or manner of calculation thereof), the conversion
period, provisions as to whether conversion will be at the option of the holders
or the Trust, the events requiring an adjustment of the conversion price and
provisions affecting conversion in the event of the redemption of such Debt
Securities.

GLOBAL SECURITIES
 
    The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities (the "Global Securities") that will be
deposited with, or on behalf of, a depositary identified in the applicable
Prospectus Supplement relating to such series. Global Securities may be issued

The specific terms of the depositary arrangement with respect to a series of
Debt Securities will be described in the applicable Prospectus Supplement
relating to such series.

                             DESCRIPTION OF SHARES
 
GENERAL
 
    The Trust is authorized to issue 100,000,000 Common Shares with a par value
of $.01 per share. Under Maryland law and the Trust's Declaration of Trust (the
"Declaration of Trust"), the Trust may increase the aggregate number of
authorized Common Shares without shareholder approval. As of March 7, 1997,
31,827,844 Common Shares were outstanding.
 
    The Trust's Board of Trustees has proposed to amend the Declaration of Trust
to authorize the Trust to issue Preferred Shares, $.01 par value per share (the
"Preferred Amendment"). The adoption of the Preferred Amendment requires the
approval of the Board of Trustees and of the holders of a majority of the
Trust's outstanding Common Shares of the form of an amendment to the Declaration
of Trust authorizing the Preferred Shares. No Preferred Shares may be issued
prior to the adoption of the Preferred Amendment.
 
    The following statements with respect to the Common Shares and Preferred
Shares (being sometimes referred to herein collectively as the "Shares") are
subject to the detailed provisions of the Declaration of Trust, the Trust's
bylaws and the proposed Preferred Amendment. These statements do not purport to
be complete or to give full effect to the terms of the provisions of the
statutory or common law and are subject to, and are qualified in their entirety
by reference to, the terms of the Declaration of Trust, the Trust's bylaws and
the proposed Preferred Amendment.
 
COMMON SHARES
 
    Holders of Common Shares are entitled to receive dividends and distributions
when and as declared by the Board of Trustees after payment of, or provision
for, any cumulated dividends and distributions on and any required redemptions
of Preferred Shares then outstanding. Holders of Common Shares have one vote per
share and non-cumulative voting rights. The Declaration of Trust establishes the
number of Trustees at not less than three nor more than seven and divides the
Trustees into three classes to be elected on a staggered basis. Upon liquidation
of the Trust, holders of Common Shares would receive their PRO RATA share of the
distributable assets of the Trust remaining after the satisfaction of prior
preferential rights of Preferred Shares and the satisfaction of all debts and
liabilities of the Trust. Holders of Common Shares do not have any preference,
conversion, exchange, preemptive or redemption rights.
 
    Outstanding Common Shares are listed on the American Stock Exchange.
American Stock Transfer & Trust Company, New York, New York is the transfer
agent for the Common Shares.
 
PREFERRED SHARES
 
    The following description of the terms of the Preferred Shares sets forth
certain general terms and provisions of the Preferred Shares to which a
Prospectus Supplement may relate. Specific terms of any series of Preferred
Shares offered by a Prospectus Supplement will be described in that Prospectus
Supplement. The description set forth below is subject to and qualified in its
entirety by reference to the Articles of Amendment to the Declaration of Trust
fixing the preferences, limitations and relative rights of a particular series
of Preferred Shares.
 
    GENERAL.  Upon the adoption of the Preferred Amendment, the Board of
Trustees would be authorized, without further shareholder action, to provide for
issuance of Preferred Shares, in one or more series, with such voting powers and
with such designations, preferences and relative, participating, optional or
other special rights, and qualifications, limitations or restrictions, as the
Board of Trustees shall approve.
 
    The Preferred Shares will have the dividend, liquidation, redemption,
conversion and voting rights set forth below unless otherwise provided in the
Prospectus Supplement relating to a particular series of Preferred Shares.
Reference is made to the Prospectus Supplement relating to the particular series
of
 
                                       20
<PAGE>
Preferred Shares offered thereby for specific terms, including: (i) the title
and liquidation preference per share of such Preferred Shares and the number of
shares offered; (ii) the price at which such series will be issued; (iii) the
dividend rate (or method of calculation), the dates on which dividends shall be
payable and the dates from which dividends shall commence to accumulate; (iv)
any redemption or sinking fund provisions of such series; (v) any conversion
provisions of such series; and (vi) any additional dividend, liquidation,
redemption, sinking fund and other rights, preferences, privileges, limitations
and restrictions of such series.
 
    The Preferred Shares will, when issued, be fully paid and nonassessable.
Unless otherwise specified in the Prospectus Supplement relating to a particular
series of Preferred Shares, each series will rank on a parity as to dividends
and distributions in the event of a liquidation with each other series of
Preferred Shares and, in all cases, will be senior to the Common Shares.
 
    DIVIDEND RIGHTS.  Holders of Preferred Shares of each series will be
entitled to receive, when, as and if declared by the Board of Trustees, out of
assets of the Trust legally available therefor, cash dividends at such rates and
on such dates as are set forth in the Prospectus Supplement relating to such
series of Preferred Shares. Such rate may be fixed or variable or both and may
be cumulative, noncumulative or partially cumulative.
 
    If the applicable Prospectus Supplement so provides, as long as any
Preferred Shares are outstanding, no dividends will be declared or paid or any
distributions be made on the Common Shares, other than a dividend payable in
Common Shares, unless the accrued dividends on each series of Preferred Shares
have been fully paid or declared and set apart for payment and the Trust shall
have set apart all amounts, if any, required to be set apart for all sinking
funds, if any, for each series of Preferred Shares.
 
    If the applicable Prospectus Supplement so provides, when dividends are not
paid in full upon any series of Preferred Shares and any other series of
Preferred Shares ranking on a parity as to dividends with such series of
Preferred Shares, all dividends declared upon such series of Preferred Shares
and any other series of Preferred Shares ranking on a parity as to dividends
will be declared PRO RATA so that the amount of dividends declared per share on
such series of Preferred Shares and such other series will in all cases bear to
each other the same ratio that accrued dividends per share on such series of
Preferred Shares and such other series bear to each other.
 
    Each series of Preferred Shares will be entitled to dividends as described
in the Prospectus Supplement relating to such series, which may be based upon
one or more methods of determination. Different series of Preferred Shares may
be entitled to dividends at different dividend rates or based upon different
methods of determination. Except as provided in the applicable Prospectus
Supplement, no series of Preferred Shares will be entitled to participate in the
earnings or assets of the Trust.
 
    RIGHTS UPON LIQUIDATION.  In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Trust, the holders of each series
of Preferred Shares will be entitled to receive out of the assets of the Trust
available for distribution to shareholders the amount stated or determined on
the basis set forth in the Prospectus Supplement relating to such series, which
may include accrued dividends, if such liquidation, dissolution or winding up is
involuntary, or may equal the current redemption price per share (otherwise than
for the sinking fund, if any, provided for such series) provided for such series
set forth in such Prospectus Supplement, if such liquidation, dissolution or
winding up is voluntary, and on such preferential basis as is set forth in such
Prospectus Supplement. If, upon any voluntary or involuntary liquidation,
dissolution or winding up of the Trust, the amounts payable with respect to
Preferred Shares of any series and any other shares of stock of the Trust
ranking as to any such distribution on a parity with such series of Preferred
Shares are not paid in full, the holders of Preferred Shares of such series and
of such other shares will share ratably in any such distribution of assets of
the Trust in proportion to the full respective preferential amounts to which
they are entitled or on such other basis as is set forth in the applicable
Prospectus Supplement. The rights, if any, of the holders of any series of
Preferred Shares to participate in the assets of the Trust remaining after the
holders of other series of Preferred Shares have
 
                                       21
<PAGE>
been paid their respective liquidation preferences upon any liquidation
dissolution or winding up of the Trust will be described in the Prospectus
Supplement relating to such series.
 
    REDEMPTION.  A series of Preferred Shares may be redeemable, in whole or in
part, at the option of the Trust, and may be subject to mandatory redemption
pursuant to a sinking fund, in each case upon terms, at the times, at the
redemption prices and for the types of consideration set forth in the Prospectus
Supplement relating to such series. The Prospectus Supplement relating to a
series of Preferred Shares which is subject to mandatory redemption shall
specify the number of shares of such series that shall be redeemed by the Trust
in each year commencing after a date to be specified, together with an amount
equal to any accrued and unpaid dividends thereon to the date of redemption.
 
    If, after giving notice or redemption to the holders of a series of
Preferred Shares, the Trust deposits with a designated bank funds sufficient to
redeem such Preferred Shares, then from and after such deposit, all shares
called for redemption will no longer be outstanding for any purpose, other than
the right to receive the redemption price and the right to convert such shares
into other classes of capital stock of the Trust. The redemption price will be
stated in the Prospectus Supplement relating to a particular series of Preferred
Shares.
 
    Except as indicated in the applicable Prospectus Supplement, the Preferred
Shares will not be subject to any mandatory redemption at the option of the
holder.
 
    SINKING FUND.  The Prospectus Supplement for any series of Preferred Shares
will state the terms, if any, of a sinking fund for the purchase or redemption
of that series.
 
    CONVERSION RIGHTS.  The Prospectus Supplement for any series of Preferred
Shares will state the terms, if any, on which shares of that series are
convertible into Common Shares or another series of Preferred Shares. The
Preferred Shares will have no preemptive rights.
 
    VOTING RIGHTS.  Except as indicated in the Prospectus Supplement relating to
a particular series of Preferred Shares, or except as expressly required by
Maryland law, a holder of Preferred Shares will not be entitled to vote. Except
as indicated in the Prospectus Supplement relating to a particular series of
Preferred Shares, in the event the Trust issues full shares of any series of
Preferred Shares, each such share will be entitled to one vote on matters on
which holders of such series of Preferred Shares are entitled to vote.
 
    Under Maryland law, the affirmative vote of the holders of a majority of the
outstanding shares of all series of Preferred Shares, voting as a separate
voting group, will be required for (i) the authorization of any class of shares
ranking prior to or on parity with Preferred Shares or the increase in the
authorized number of any such shares, (ii) any increase in the authorized number
of Preferred Shares and (iii) certain amendments to the Declaration of Trust
that may be adverse to the rights of Preferred Shares outstanding.
 
    TRANSFER AGENT AND REGISTRAR.  The transfer agent, registrar and dividend
disbursement agent for a series of Preferred Shares will be selected by the
Trust and be described in the applicable Prospectus Supplement. The registrar
for Preferred Shares will send notices to shareholders of any meetings at which
holders of Preferred Shares have the right to vote on any matter.
 
BUSINESS COMBINATION PROVISIONS
 
    The Declaration of Trust provides that any merger, consolidation or
liquidation of the Trust, or any sale of all or substantially all of its assets,
must be approved by a majority of the Trustees, and that if any such transaction
is with, into or to a Related Shareholder (defined as a person or entity
beneficially owning, directly or indirectly, 5% or more of the outstanding
Shares), the transaction must be approved by a majority of the Trustees not
appointed or nominated by or acting on behalf of the Related Shareholder or an
affiliate or associate of the Related Shareholder.
 
                                       22
<PAGE>
    The Trust, as permitted by Maryland Law, has expressly elected to be
governed by the special voting requirement of the Maryland Corporations and
Associates Article (the "Special Voting Article"). The Special Voting Article
establishes special requirements with respect to "business combinations" between
an "interested stockholder" and a Maryland corporation unless exemptions are
applicable. Among other things, the Special Voting Article prohibits, for a
period of five years, a merger and other specific or similar transactions
between a Maryland corporation and an interested stockholder and requires a
super majority vote for such transactions after the end of such five-year
period. (For the purposes of the Special Voting Article and the Control Share
Article (described below), a "Maryland corporation" includes a Maryland real
estate investment trust. They are referred to collectively in this section as a
"Maryland company.")
 
    "Interested stockholders" are all persons owning beneficially, directly or
indirectly, more than 10% of the outstanding voting stock of a Maryland company.
"Business combinations" include any merger or similar transaction subject to a
statutory vote and additional transactions involving transfers of assets or
securities in specified amounts to interested stockholders or their affiliates.
Unless an exemption is available, transactions of these types may not be
consummated between a Maryland company and an interested stockholder and,
thereafter, may not be consummated unless recommended by the board of the
Maryland company and approved by the affirmative vote of at least 80% of the
votes entitled to be cast by all holders of outstanding shares of voting stock
and 66 2/3% of the votes entitled to be cast by all holders of outstanding
shares of voting stock other than the interested stockholder unless, among other
things, the company's stockholders receive a minimum price (as defined in the
Special Voting Article) for their shares and the consideration is received in
cash or in the same form as previously paid by the interested stockholder for
its shares.
 
    A business combination with an interested stockholder which is approved by
the board of a Maryland company at any time before an interested stockholder
first becomes an interested stockholder is not subject to the special voting
requirements or fair price provisions of the Special Voting Article. An
amendment to a Maryland company's charter electing not to be subject to the
foregoing requirements must be approved by the affirmative vote of at least 80%
of the votes entitled to be cast by all holders of outstanding shares of voting
stock and 66 2/3% of the votes entitled to be cast by holders of outstanding
shares of voting stock who are not interested stockholders. Any such amendment
is not effective until eighteen months after the vote of stockholders and does
not apply to any business combination of a company with a stockholder who was an
interested stockholder on the date of the stockholder vote.
 
    The Trust, as permitted by Maryland law, has also expressly elected to be
governed by the control share provisions of the Maryland Corporations and
Associates Article (the "Control Share Article"). Under the Control Share
Article, "control shares" of a Maryland company acquired in a "control share
acquisition" have no voting rights except to the extent approved a vote of
two-thirds of the votes entitled to be cast on the matter, excluding shares of
stock owned by the acquirer or by officers or directors who are employees of the
company. "Control shares" are voting shares of stock which, if aggregated with
all other shares of stock previously acquired by such a person, would entitle
the acquirer to exercise voting power in electing directors within one of the
following ranges of voting power: (i) 20% or more but less than 33 1/3%, or
33 1/3% or more but less than a majority, or (iii) a majority of all voting
power. Control shares do not include shares the acquiring person is then
entitled to vote as a result of having previously obtained shareholder approval.
A "control share acquisition" means, subject to certain exceptions, the
acquisition of, ownership of, or the power to direct the exercise of voting
power with respect to, control shares.
 
    A person who has made or proposes to make a control share acquisition upon
satisfaction of certain conditions (including an undertaking to pay expenses)
may compel the board of directors to call a special meeting of shareholders to
be held within 50 days of demand to consider the voting rights of the shares. If
no request for a meeting is made, the Maryland company may itself present the
question at any shareholders' meeting.
 
                                       23
<PAGE>
    If voting rights are not approved at the meeting or if the acquiring person
does not deliver an acquiring person statement as permitted by the statute,
then, subject to certain conditions and limitations, the Maryland company may
redeem any or all of the control shares (except those for which voting rights
have previously been approved) for fair value, without regard to voting rights.
Fair value shall be determined as of the date of the meeting of the shareholders
at which the voting rights of the control shares are considered but not
approved. If no such meeting is held, fair value shall be determined as of the
date of the last acquisition of control shares by the acquiring person. If
voting rights for control shares are approved at a shareholders' meeting and the
acquirer becomes entitled to a majority of the shares entitled to vote, all
other shareholders may exercise appraisal rights. The fair value of the shares
as determined for purposes of such appraisal rights may not be less than the
highest price per share paid in the control share acquisition, and certain
limitations and restrictions otherwise applicable to the exercise of dissenters'
rights do not apply in the context of a control share acquisition.
 
    The Control Share Article does not apply to shares acquired in a merger,
consolidation or share exchange if the Maryland company is a party to the
transaction, to acquisitions approved or exempted by the charter or bylaws of
the Maryland company or to shares acquired before November 4, 1988 or pursuant
to a contract entered into before November 4, 1988.
 
    The foregoing provisions may have the effect of discouraging unilateral
tender offers or other takeover proposals which certain shareholders might deem
in their interests or pursuant to which they might receive a substantial premium
for their Shares. The Control Share Article in particular has the effect of
making a unilateral tender offer or other takeover of the Trust more difficult.
The provisions could also have the effect of insulating current management
against the possibility of removal and could, by possibly reducing temporary
fluctuations in market price caused by accumulations of Shares, deprive
shareholders of opportunities to sell at a temporarily higher market price.
 
EXCESS SHARE PROVISIONS
 
    For the Trust to qualify as a REIT under the Code, in any taxable year, not
more than 50% in value of its outstanding Shares may be owned, directly or
indirectly, by five or fewer individuals during the last six months of such
year, and the Shares must be owned by 100 or more persons during at least 335
days of a taxable year or a proportionate part of a taxable year less than 12
months. In order to meet these and other requirements, the Trustees have the
power to redeem or prohibit the transfer of a sufficient number of Shares to
maintain or bring the ownership of the Shares into conformity with such
requirements. In connection with the foregoing, if the Trustees shall, at any
time and in good faith, be of the opinion that direct or indirect ownership of
Shares representing more than 10% in value of the total Shares outstanding (the
"Excess Shares") has or may become concentrated in the hands of one beneficial
owner, the Trustees shall have the power (i) to repurchase from any shareholder
of the Trust such Excess Shares and (ii) to refuse to sell, transfer or deliver
Shares to any person whose acquisition of such Shares would, in the opinion of
the Trustees, result in the direct or indirect beneficial ownership by any
person of Shares representing more than 10% in value of the outstanding Shares.
The purchase price for any Shares so repurchased shall be at cost or at the last
sale price of the Share as of the date immediately preceding the day on which
the demand for repurchase is mailed, whichever price is higher. From and after
the date fixed for repurchase by the Trustees, and so long as payment of the
purchase price for the Shares to be so repurchased shall have been made or duly
provided for, the holder of any Excess Shares so called for repurchase shall
cease to be entitled to distributions, voting rights and other benefits with
respect to such Shares, except the right to payment of the purchase price for
the Shares.
 
    The Declaration of Trust includes an excess share provision to ensure that
any rent paid to the trust by a "sister corporation" not become disqualified as
rent from real property by virtue of Section 856(d)(2)(B) of the Code. Under
these provisions, the Trustees have the power (i) by lot or other means deemed
equitable to call for purchase from any shareholder such numbers of Shares as
shall be sufficient in the opinion of the Trustees to maintain or bring the
direct or indirect ownership of Shares in conformity
 
                                       24
<PAGE>
with the requirements of Section 856(d)(2)(B), and (ii) to refuse to register
the transfer of Shares to any person whose ownership would jeopardize the
Trust's compliance with Section 856(d)(2)(B). For purposes of this provision,
the term "sister corporation" means a corporation the shares of which are owned
by exactly or substantially the same persons and in exactly or substantially the
same numbers as are the Shares. This provision shall apply even if a "sister
corporation" does not exist (i) at the time the Trustees determine that the
ownership of Shares has or may become so concentrated, or (ii) at the time the
Trustees call Shares for purchase or refuse to register the transfer of Shares.
The purchase price for the Shares purchased pursuant thereto shall be equal to
the fair market value of such Shares as reflected in the closing price for such
Shares on the principal stock exchange on which such Shares are listed or, if
such Shares are not listed, then the last bid for the Shares, as of the close of
business on the date fixed by the Trustees for such purchase or, if no such
quotation is available, as shall be determined in good faith by the Trustees.
From and after the date fixed for purchase by the Trustees, the holder of any
Shares so called for purchase shall cease to be entitled to dividends, voting
rights and other benefits with respect to such Shares, except the right to
payment of the purchase price fixed as aforesaid.
 
    In order to further assure that ownership of the Shares does not become so
concentrated, the Declaration of Trust provides that if any transfer of Shares
would prevent amounts received by the Trust from a "sister corporation," if one
existed, from qualifying as "rents from real property" as defined in Section
856(d) of the Code, by virtue of the application of Section 856(d)(2)(B) of the
Code, the transfer shall be void AB INITIO and the intended transferee of such
Shares shall be deemed never to have had an interest therein. If this provision
is deemed void or invalid by virtue of any legal decision, statute, rule or
regulation, then the transferee of such Shares is deemed to have acted as an
agent on behalf of the Trust. Furthermore, the Declaration of Trust provides
that shareholders shall upon demand disclose to the Trustees in writing such
information with respect to their direct and indirect ownership of the Shares as
the Trustees deem necessary to determine whether the Trust satisfies the
provisions of Sections 856(a)(5) and (6) and Section 856(d) of the Code or the
regulations thereunder, as the same shall from time to time be amended, or to
comply with the requirements of any other taxing authority.
 
    Similarly to the business combination provisions, the excess share
provisions may deter or render more difficult attempts by third parties to
obtain control of the Trust if such attempts are not supported by the Board of
Trustees.
 
TAXATION
 
    The Trust has elected to be taxed as a REIT under the Code. A REIT which
meets certain qualifications is relieved of federal income taxes on ordinary
income and capital gains distributed to shareholders. In the opinion of Arent
Fox Kintner Plotkin & Kahn, legal counsel for WRIT, the Trust has qualified as a
real estate investment trust for the years 1992--1996 and its present and
contemplated method of operation will put it in a position to continue to so
qualify. David M. Osnos, a trustee, is a partner of such firm.

<PAGE>
                      DESCRIPTION OF COMMON SHARE WARRANTS
 
    The Trust may issue Common Share Warrants for the purchase of Common Shares.
Common Share Warrants may be issued independently or together with any other
Offered Securities offered by any Prospectus Supplement and may be attached to
or separate from such Offered Securities. Each series of Common Share Warrants
will be issued under a separate warrant agreement (each, a "Warrant Agreement")
to be entered into between the Trust and a warrant agent specified in the
applicable Prospectus Supplement (the "Warrant Agent"). The Warrant Agent will
act solely as an agent of the Trust in connection with the Common Share Warrants
of such series and will not assume any obligation or relationship of agency or
trust for or with any holders or beneficial owners of Common Share Warrants.
 
    The applicable Prospectus Supplement will describe the terms of the Common
Share Warrants in respect of which this Prospectus is being delivered,
including, where applicable, the following: (i) the title of such Common Share
Warrants; (ii) the aggregate number of such Common Share Warrants; (iii) the
price or prices at which such Common Share Warrants will be issued; (iv) the
designation, number and terms of the Common Shares purchasable upon exercise of
such Common Share Warrants; (v) the designation and terms of the other Offered
Securities with which such Common Share Warrants are issued and the number of
such Common Share Warrants issued with each such Offered Security; (vi) the
date, if any, on and after which such Common Share Warrants and the related
Common Shares will be separately transferable; (vii) the price at which each
Common Share purchasable upon exercise of such Common Share Warrants may be
purchased; (viii) the date on which the right to exercise such Common Share
Warrants shall commence and the date on which such right shall expire; (ix) the
minimum and maximum amount of such Common Share Warrants which may be exercised
at any one time; (x) information with respect to book-entry procedures, if any;
(xi) a discussion of certain federal income tax considerations; and (xii) any

and limitations relating to the exchange and exercise of such Common Share
Warrants.

                              PLAN OF DISTRIBUTION
 
    The Trust may sell the Offered Securities to one or more underwriters for
public offering and sale by them or may sell the Offered Securities to investors
directly or through agents. Any such underwriter or agent involved in the offer
and sale of the Offered Securities will be named in the applicable Prospectus
Supplement.
 
    Underwriters may offer and sell the Offered Securities at a fixed price or
prices, which may be changed, at prices related to the prevailing market prices
at the time of sale or at negotiated prices. The Trust also may, from time to
time, authorize underwriters acting as the Trust's agents to offer and sell the
Offered Securities upon the terms and conditions as are set forth in the
applicable Prospectus Supplement. In connection with the sale of Offered
Securities, underwriters may be deemed to have received compensation from the
Trust in the form of underwriting discounts or commissions and may also receive
commissions from purchasers of Offered Securities for whom they may act as
agent. Underwriters may sell Offered Securities to or through dealers, and such
dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agent.
 
    Any underwriting compensation paid by the Trust to underwriters or agents in
connection with the offering of Offered Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the applicable Prospectus Supplement. Underwriters, dealers
and agents participating in the distribution of the Offered Securities may be
deemed to be underwriters, and any discounts and commission received by them and
any profit realized by them on resale of the Offered Securities may be deemed to
be underwriting discounts and commissions, under the Securities Act.
Underwriters, dealers and agents may be entitled, under agreements entered into
with the Trust, to indemnification against the contribution toward certain civil
liabilities, including liabilities under the Securities Act.
 
    If so indicated in the applicable Prospectus Supplement, the Trust will
authorize dealers acting as the Trust's agents to solicit offers by certain
institutions to purchase Offered Securities from the Trust at the public
offering price set forth in such Prospectus Supplement pursuant to delayed
delivery contracts ("Contracts") providing for payment and delivery on the date
or dates stated in such Prospectus Supplement. Each Contract will be for an
amount not less than, and the aggregate principal amount of Offered Securities
sold pursuant to Contracts shall be not less nor more than, the respective
amounts stated in the applicable Prospectus Supplement. Institutions with whom
Contracts, when authorized, may be made include commercial and savings banks,
insurance companies, pension funds, investment companies, educational and
charitable institutions and other institutions but will in all cases be subject
to the approval of the Trust. Contracts will not be subject to any conditions
except (i) the purchase by an institution of the Offered Securities covered by
its Contracts shall not at the time of delivery be prohibited under the laws of
any jurisdiction in the United States to which such institution is subject, and
(ii) if the Offered Securities are being sold to underwriters, the Trust shall
have sold to such underwriters the total principal amount of the Offered
Securities less the principal amount thereof covered by Contracts.
 
    Certain of the underwriters and their affiliates may engage in transactions
with and perform services for the Trust and its subsidiaries in the ordinary
course of business.
 
                                 LEGAL OPINIONS
 
    The legality of the Offered Securities is being passed upon for the Trust by
Arent Fox Kintner Plotkin & Kahn, Washington, D.C. David M. Osnos, a trustee of
the Trust, is a partner of Arent Fox Kintner Plotkin & Kahn. Andrews & Kurth
L.L.P., Washington, D.C., will act as counsel to any underwriters, dealers or
agents.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Registrant's Declaration of Trust dated April 5, 1996 provides that no
Trustee or officer of the Registrant shall be personally liable, in tort,
contract or otherwise, in connection with the Registrant's property or the
affairs of the Registrant, or on account of his own acts or omissions to the
Registrant, or to any shareholder, Trustee, officer or agent thereof except (1)
to the extent that it is proved that such trustee or officer actually received
an improper benefit or profit in money, property, or services, in which case any
such liability shall not exceed the amount of the benefit or profit in money,
property, or services actually received; or (2) to the extent that a judgment or
other final adjudication adverse to such Trustee or officer is entered in a
proceeding based on a finding in the proceeding that such Trustee's or officer's
action or failure to act was the result of active and deliberate dishonesty and
was material to the cause of action adjudicated in the proceeding. All persons
shall look solely to the Registrant's property for satisfaction of claims of any
nature in connection with the affairs of the Registrant. The Registrant's
Declaration of Trust further provides for the indemnification of the
Registrant's Trustees and officers to the fullest extent permitted by Section
2-418 of the Maryland General Corporation Law.

ITEM 17. UNDERTAKINGS
 
    (a) The Registrant hereby undertakes:
 
       (1) To file, during any period in which offers or sales are being made of
           the securities registered hereby, a post-effective amendment to this
           Registrant Statement;
 
            (i) To include any prospectus required by Section 10(a)(3) of the
                Securities Act;
 
            (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 this Registration Statement.
                 Notwithstanding the foregoing, any increase or decrease in
                 volume of securities offered (if the total dollar value of
                 securities offered would not exceed that which was registered)
                 and any deviation from the low or high end of the estimated
                 maximum offering range may be reflected in the form of
                 prospectus filed with the Commission pursuant to Rule 424(b)
                 if, in the aggregate, the changes in volume and price represent
                 no more than a 20% change in the maximum aggregate offering
                 price set forth in the "Calculation of Registration Fee" table
                 in the effective registration statement; and
 
                                      II-2
<PAGE>
           (iii) To include any material information with respect to the plan of
                 distribution not previously disclosed in this Registration
                 Statement or any material change to such information in this
                 Registration Statement;
 
          PROVIDED, HOWEVER, that the undertakings set forth in paragraphs
           (1)(i) and (1)(ii) above do not apply if 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 Exchange Act that are incorporated
           by reference in this Registration Statement.
 
       (2) That, for the purpose of determining any liability under the
           Securities Act, 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.
 
       (3) To remove from registration by means of a post-effective amendment
           any of the securities being registered which remain unsold at the
           termination of the offering.
 
    (b) The Registrant hereby further undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act 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 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 Commission such indemnification is
against public policy as expressed in the Securities Act 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, unless in the opinion of its counsel the matter has
been settled by controlling precedent, will submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    The undersigned Registrant 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 the form of prospectus filed by the Registrant 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.
 
       (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 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.
 
    The undersigned Registrant hereby undertakes to file an application for
purposes of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and
regulations prescribed by the Commission under Section 305(b)(2) of the Act.

                                UNDERWRITING AGREEMENT



                                                           ____________, 199_


[Name(s) of Representative(s)]




Ladies and Gentlemen:

    Washington Real Estate Investment Trust, a real estate investment trust 
organized under the laws of the State of Maryland (the "Company"), proposes 
to issue and sell senior or subordinated debt securities (the "Debt 
Securities"), from time to time, in one or more offerings on terms to be 
determined at the time of sale.  The Debt Securities will be issued in one or 
more series as senior indebtedness (the "Senior Debt Securities") under an 
indenture, dated as of August 1, 1996 (the "Senior Indenture"), between the 
Company and The First National Bank of Chicago, as trustee (the "Senior 
Indenture Trustee"), or as subordinated indebtedness (the "Subordinated Debt 
Securities") under an indenture, dated as of _______, 1997 (the "Subordinated 
Indenture," and together with the Senior Indenture, the "Indentures," and 
each, an "Indenture"), between the Company and _______, as trustee, (the 
"Subordinated Indenture Trustee", and together with the Senior Indenture 
Trustee the "Indenture Trustees" and each, and "Indenture Trustee") .  Each 
series of Debt Securities may vary, as applicable, as to title, aggregate 
principal amount, rank, interest rate or formula and timing of payments 
thereof, stated maturity date, redemption and/or repayment provisions, 
sinking fund requirements, conversion provisions (and terms of the related 
Underlying Securities (as defined below)), and any other variable terms 
established by or pursuant to the applicable Indenture.


<PAGE>

    As used herein, "Debt Securities" shall mean the Senior Debt Securities 
or Subordinated Debt Securities, or any combination thereof, initially 
issuable by the Company and "Underlying Securities" shall mean the Company's 
common shares of beneficial interest, par value $.01 per share (the "Common 
Shares") or preferred shares of beneficial interest, par value $.01 per share 
(the "Preferred Shares"), issuable upon conversion of the Senior Debt 
Securities or Subordinated Debt Securities.  As used herein, "you" and 
"your", unless the context otherwise requires, shall mean the parties to whom 
this Agreement is addressed together with the other parties, if any, 
identified in the applicable Terms Agreement (as hereinafter defined) as 
additional co-managers with respect to the Underwritten Securities (as 
hereinafter defined) purchased pursuant thereto.

    Whenever the Company determines to make an offering of Debt Securities 
through you or through an underwriting syndicate managed by you, the Company 
will enter into an agreement (each, a "Terms Agreement") providing for the 
sale of such Debt Securities (the "Underwritten Securities") to, and the 
purchase and offering thereof by, you and such other underwriters, if any, 
selected by you (the "Underwriters", which term shall include you, whether 
acting alone or as  members of an underwriting syndicate, as well as any 
Underwriter substituted pursuant to Section 10 hereof). The Terms Agreement 
relating to the offering of Underwritten Securities shall specify the 
aggregate principal amount of Underwritten Securities to be initially issued 
(the "Initial Underwritten Securities"), the name of each Underwriter 
participating in such offering (subject to substitution as provided in 
Section 10 hereof) and the name of each additional co-manager, if any, 
participating in such offering, the aggregate principal amount of Initial 
Underwritten Securities which each such Underwriter severally agrees to 
purchase, whether such offering is on a fixed or variable price basis and, if 
on a fixed price basis, the initial offering price, the price at which the 
Initial Underwritten Securities are to be purchased by the Underwriters, the 
form, time, date and place of delivery and payment of the Initial 
Underwritten Securities and any other material variable terms of the Initial 
Underwritten Securities.  In addition, such Terms Agreement shall specify 
whether the Company has agreed to grant to the Underwriters an option to 
purchase additional Debt Securities to cover over-allotments, if any, and the 
aggregate principal amount of Debt Securities subject to such option (the 
"Option Underwritten Securities").  As used herein, the term "Underwritten 
Securities" shall include the Initial Underwritten Securities and all or any 
portion of any Option Underwritten Securities.  The Terms Agreement, which 
shall be substantially in the form of Exhibit A hereto, may take the form of 
an exchange of any standard form of written telecommunication between the 
Company and you.  Each offering of Underwritten Securities through you or 
through an underwriting syndicate managed by you will be governed by this 
Underwriting Agreement, as supplemented by the applicable Terms Agreement.

    The Company has filed with the Securities and Exchange Commission (the 
"Commission") a registration statement on Form S-3 (No. 333-_____) 
[and pre-effective amendment no. 1 thereto] for the registration of the Debt 
Securities, Common Shares, Preferred Shares, Warrants to Purchase Common 
Shares and the Underlying Securities under the Securities Act of 1933, as 
amended (the "1933 Act"), and the offering thereof from time to time in 
accordance with Rule 415 of the rules and regulations of the Commission under 
the 1933 Act (the "1933 Act Regulations"), and the Company has filed such 
post-effective amendments thereto as may be required prior to the execution 
of the 

                                   -2-

<PAGE>

applicable Terms Agreement.  Such registration statement (as so amended, if 
applicable) has been declared effective by the Commission and each Indenture 
has been duly qualified under the Trust Indenture Act of 1939, as amended 
(the "1939 Act").  Such registration statement (as so amended, if 
applicable), including the information, if any, deemed to be a part thereof 
pursuant to Rule 434(d) of the 1933 Act Regulations (the "Rule 434 
Information"), is referred to herein as the "Registration Statement"; and the 
final prospectus and the final prospectus supplement relating to the offering 
of the Underwritten Securities, in the form first furnished to the 
Underwriters by the Company for use in connection with the offering of the 
Underwritten Securities, are collectively referred to herein as the 
"Prospectus"; provided, however, that all references to the "Registration 
Statement" and the "Prospectus" shall also be deemed to include all documents 
incorporated therein by reference pursuant to the Securities Exchange Act of 
1934, as amended (the "1934 Act"), prior to the execution of the applicable 
Terms Agreement; provided, further, that if the Company files a registration 
statement with the Commission pursuant to Rule 462(b) of the 1933 Act 
Regulations (the "Rule 462 Registration Statement"), then, after such filing, 
all references to "Registration Statement" shall also be deemed to include 
the Rule 462 Registration Statement; and provided, further, that if the 
Company elects to rely upon Rule 434 of the 1933 Act Regulations, then all 
references to "Prospectus" shall also be deemed to include the final or 
preliminary prospectus, as the case may be, and the applicable term sheet or 
abbreviated term sheet (the "Term Sheet"), as the case may be, in the form 
first furnished to the Underwriters by the Company in reliance upon Rule 434 
of the 1933 Act Regulations, and all references in this Underwriting 
Agreement to the date of the Prospectus shall mean the date of the Term 
Sheet.  For purposes of this Underwriting Agreement, all references to the 
Registration Statement, Prospectus, Term Sheet or preliminary prospectus or 
to any amendment or supplement to any of the foregoing shall be deemed to 
include any copy filed with the Commission pursuant to its Electronic Data 
Gathering, Analysis and Retrieval system ("EDGAR"). 

    All references in this Underwriting Agreement to financial statements and 
schedules and other information which is "contained," "included" or "stated" 
(or other references of like import) in the Registration Statement, 
Prospectus or preliminary prospectus shall be deemed to mean and include all 
such financial statements and schedules and other information which is 
incorporated by reference in the Registration Statement, Prospectus or 
preliminary prospectus, as the case may be; and all references in this 
Underwriting Agreement to amendments or supplements to the Registration 
Statement, Prospectus or preliminary prospectus shall be deemed to mean and 
include the filing of any document under the 1934 Act which is incorporated 
by reference in the Registration Statement, Prospectus or preliminary

       (1)  The Company meets the requirements for use of Form S-3 under the 
    1933 Act.  Each of the Registration Statement and any Rule 462(b) 
    Registration Statement has become effective under the 1933 Act and no 
    stop order suspending the effectiveness of the Registration Statement or 
    any Rule 462(b) Registration Statement has been issued under the 1933 Act 
    and no proceedings for that purpose have been instituted or are pending 
    or, to the knowledge of the Company, are contemplated by the Commission, 
    and any request on the part of the Commission for additional information 
    has been complied with.  In addition, each Indenture has been duly 
    qualified under the 1939 Act.

         At the respective times the Registration Statement, any Rule 462(b) 
    Registration Statement and any post-effective amendments thereto 
    (including the filing of the Company's most recent Annual Report on Form 
    10-K with the Commission (the "Annual Report on Form 10-K")) became 
    effective and at each Representation Date, the Registration Statement, 
    any Rule 462(b) Registration Statement and any amendments and supplements 
    thereto complied and will comply in all material respects with the 
    requirements of the 1933 Act and the 1933 Act Regulations and the 1939 
    Act and the rules and regulations of the Commission under the 1939 Act 
    (the "1939 Act Regulations") and did not and will not 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. At the date of the Prospectus, at the Closing Time and at 
    each Date of Delivery, if any, the Prospectus and any amendments and 
    supplements thereto did not and will not 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.  If the Company elects to rely upon Rule 
    434 of the 1933 Act Regulations, the Company will comply with the 
    requirements of Rule 434.  Notwithstanding the foregoing, the 
    representations and warranties in this subsection shall not apply to 
    statements in or omissions from the Registration Statement or the 
    Prospectus made in reliance upon and in conformity with information 
    furnished to the Company in writing by any Underwriter through you 
    expressly for use in the Registration Statement or the Prospectus.

              Each preliminary prospectus and prospectus filed as part of the 
    Registration Statement as originally filed or as part of any amendment 
    thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when 
    so filed in all material respects with the 1933 Act Regulations and each 
    preliminary prospectus and the Prospectus delivered to the Underwriters 
    for use in connection with the offering of Underwritten Securities will, 
    at the time of such delivery, be identical to any electronically 
    transmitted copies thereof filed with the Commission pursuant to EDGAR, 
    except to the extent permitted by Regulation S-T.

       (2)  The documents incorporated or deemed to be incorporated by 
    reference in the Registration Statement and the Prospectus, at the time 
    they were or hereafter are filed with the Commission, complied and will 
    comply in all material respects with the requirements of the 1934 Act and 
    the rules and regulations of the Commission thereunder (the "1934 Act 
    Regulations") and, when read together with the other information in the 
    Prospectus, at the 

                                   -4-

<PAGE>

    date of the Prospectus, at the Closing Time and at each Date of Delivery, 
    if any, did not and will not include an untrue statement of a material 
    fact or omit to state a material fact necessary to make the statements 
    therein, in the light of the circumstances under which they were made, 
    not misleading.

       (3)  The accountants who certified the financial statements and any 
    supporting schedules thereto included in the Registration Statement and 
    the Prospectus are independent public accountants as required by the 1933 
    Act and the 1933 Act Regulations.

       (4)  The financial statements of the Company included in the 
    Registration Statement and the Prospectus, together with the related 
    schedules and notes, present fairly the financial position of the Company 
    and its consolidated subsidiaries, at the dates indicated and the 
    statement of operations, shareholders' equity and cash flows of the 
    Company and its consolidated subsidiaries for the periods specified.  
    Such financial statements have been prepared in conformity with generally 
    accepted accounting principles ("GAAP") applied on a consistent basis 
    throughout the periods involved.  The supporting schedules, if any, 
    included in the Registration Statement and the Prospectus present fairly 
    in accordance with GAAP the information required to be stated therein.  
    The selected financial data and the summary financial information 
    included in the Prospectus present fairly the information shown therein 
    and have been compiled on a basis consistent with that of the audited 
    financial statements included in the Registration Statement and the 
    Prospectus.  Any historical summaries of revenue and certain operating 
    expenses included or incorporated by reference in the Registration 
    Statement and the Prospectus present fairly the revenue and those 
    operating expenses included in such summaries of the properties related 
    thereto for the periods specified in conformity with GAAP.  In addition, 
    any pro forma financial statements of the Company and its subsidiaries 
    and the related notes thereto included in the Registration Statement and 
    the Prospectus present fairly the information shown therein, have been 
    prepared in accordance with the Commission's rules and guidelines with 
    respect to pro forma financial statements and have been properly compiled 
    on the bases described therein, and the assumptions used in the 
    preparation thereof are reasonable and the adjustments used therein are 
    appropriate to give effect to the transactions and circumstances referred 
    to therein.

        (5)  Since the respective dates as of which information is given in 
    the Registration Statement and the Prospectus, except as otherwise stated 
    therein, (A) there has been no material adverse change in the condition, 
    financial or otherwise, or in the earnings, business affairs or business 
    prospects of the Company and its subsidiaries considered as one 
    enterprise, whether or not arising in the ordinary course of business (a 
    "Material Adverse Effect"), (B) there have been no transactions entered 
    into by the Company or any of its subsidiaries, other than those arising 
    in the ordinary course of business, which are material with respect to 
    the Company and its subsidiaries considered as one enterprise and (C) 
    except for regular dividends on the Company's shares of beneficial 
    interest, in amounts per share that are consistent with past practice, 
    there has been no dividend or distribution of any kind declared, paid or 
    made by the Company on any class of its capital stock.

                                   -5-

        (6)  The Company has been duly organized and is validly existing as a 
    real estate investment trust of unlimited duration with transferable 
    shares of beneficial interest in good standing under the laws of the 
    State of Maryland, with full power and authority to own, lease and 
    operate its properties and to conduct its business as described in the 
    Prospectus and to enter into and perform its obligations under, or as 
    contemplated under, this Underwriting Agreement and the applicable Terms 
    Agreement.  The Company is duly qualified to transact business in each 
    other jurisdiction in which such qualification is required, whether by 
    reason of the ownership or leasing of property or the conduct of 
    business, except where the failure to so qualify would not result in a 
    Material Adverse Effect.

        (7)  Each "significant subsidiary" of the Company (as such term is 
    defined in Rule 1-02 of Regulation S-X promulgated under the 1933 Act) 
    (each, a "Subsidiary" and, collectively, the "Subsidiaries") (which term 
    includes corporations, limited and general partnerships, joint ventures 
    and other entities, and includes direct and indirect subsidiaries), if 
    any, has been duly organized and is validly existing as a corporation or 
    partnership, as the case may be, in good standing under the laws of the 
    jurisdiction of its organization, has power and authority to own, lease 
    and operate its properties and to conduct its business as described in 
    the Prospectus and is duly qualified to transact business and is in good 
    standing in each jurisdiction in which such qualification is required, 
    whether by reason of the ownership or leasing of property or the conduct 
    of business, except where the failure to so qualify or be in good 
    standing would not result in a Material Adverse Effect.  Except as 
    otherwise stated in the Registration Statement and the Prospectus, all of 
    the issued and outstanding capital stock or other ownership interests of 
    each Subsidiary have been duly authorized and validly issued, are fully 
    paid and non-assessable and are owned by the Company, directly or through 
    subsidiaries, free and clear of any security interest, mortgage, pledge, 
    lien, encumbrance, claim or equity.

        (8) The authorized, issued and outstanding shares of beneficial 
    interest of the Company are as set forth in the Prospectus under the 
    caption "Capitalization" (except for subsequent issuances thereof, if 
    any, contemplated under this Underwriting Agreement, pursuant to dividend 
    reinvestment plans, reservations, agreements or employee benefit plans 
    referred to in the Prospectus or pursuant to the exercise of convertible 
    securities or options referred to in the Prospectus). Such shares of 
    beneficial interest have been duly authorized and validly issued by the 
    Company and are fully paid and non-assessable, and none of such shares of 
    beneficial interest was issued in violation of preemptive or other 
    similar rights of any security holder of the Company.

        (9)  This Underwriting Agreement has been, and the applicable Terms 
    Agreement as of the date thereof will have been, duly authorized, 
    executed and delivered by the Company.

        (10) The Underwritten Securities being sold pursuant to the 
    applicable Terms Agreement have been, or as of the date of such Terms 
    Agreement will have been, duly authorized by the Company for issuance and 
    sale pursuant to this Underwriting Agreement and such Terms 

                                  -6-

<PAGE>

    Agreement.  Such Underwritten Securities, when issued and authenticated 
    in the manner provided for in the applicable Indenture and delivered 
    against payment of the consideration therefor specified in such Terms 
    Agreement, will constitute valid and legally binding obligations of the 
    Company, enforceable against the Company in accordance with their terms, 
    except as the enforcement thereof may be limited by bankruptcy, 
    insolvency, reorganization, moratorium or other similar laws relating to 
    or affecting creditors' rights generally or by general equitable 
    principles, and except further as enforcement thereof may be limited by 
    (A) requirements that a claim with respect to any Debt Securities 
    denominated other than in U.S. dollars (or a foreign or composite 
    currency judgment in respect of such claim) be converted into U.S. 
    dollars at a rate of exchange prevailing on a date determined pursuant to 
    applicable law or (B) governmental authority to limit, delay or prohibit 
    the making of payments outside the United States.  Such Underwritten 
    Securities will be in the form contemplated by, and each registered 
    holder thereof is entitled to the benefits of, the applicable Indenture.

        (11)  Each applicable  Indenture has been duly authorized, executed 
    and delivered by the Company and constitutes a valid and legally binding 
    agreement of the Company, enforceable against the Company in accordance 
    with its terms, except as the enforcement thereof may be limited by 
    bankruptcy, insolvency, reorganization, moratorium or other similar laws 
    relating to or affecting creditors' rights generally or by general 
    equitable principles.  

       (12) If applicable, the Underlying Securities have been, or as of the 
    date of the applicable Terms Agreement will have been, duly authorized 
    and reserved for issuance by the Company upon conversion of the related 
    Senior Debt Securities or Subordinated Debt Securities, as applicable.  
    The Underlying Securities, when issued upon such conversion, will be 
    validly issued, fully paid and non-assessable and will not be subject to 
    preemptive or other similar rights of any securityholder of the Company.

        (13)  The Underwritten Securities being sold pursuant to the 
    applicable Terms Agreement and each applicable Indenture, as of the date 
    of the Prospectus, and any Underlying Securities, when issued and 
    delivered in accordance with the terms of the related Underwritten 
    Securities, will conform in all material respects to the statements 
    relating thereto contained in the Prospectus and will be in substantially 
    the form filed or incorporated by reference, as the case may be, as an 
    exhibit to the Registration Statement.

        (14)  Neither the Company nor any of its subsidiaries is in violation 
    of its declaration of trust, partnership agreement, charter, by-laws or 
    other organizational document or in default in the performance or 
    observance of any obligation, agreement, covenant or condition contained 
    in any contract, indenture, mortgage, deed of trust, loan or credit 
    agreement, note, lease or other agreement or instrument to which the 
    Company or any of its subsidiaries is a party or by which it or any of 
    them may be bound, or to which any of the property or assets of the 
    Company or any of its subsidiaries is subject, except for such defaults 
    that would not result in a Material Adverse Effect.  The execution, 
    delivery and performance of this 

                                   -7-

<PAGE>

    Underwriting Agreement, the applicable Terms Agreement and each applicable 
    Indenture and any other agreement or instrument entered into or issued or 
    to be entered into or issued by the Company in connection with the 
    transactions contemplated hereby or thereby or in the Registration 
    Statement and the Prospectus and the consummation of the transactions 
    contemplated herein and in the Registration Statement and the Prospectus 
    and compliance by the Company with its obligations hereunder and 
    thereunder have been duly authorized by all necessary action on the part 
    of the Company  and do not and will not, whether with or without the 
    giving of notice or passage of time or both, conflict with or constitute 
    a breach of, or default under, or result in the creation or imposition of 
    any lien, charge or encumbrance upon any assets, properties or operations 
    of the Company or any of its subsidiaries pursuant to, any contract, 
    indenture, mortgage, deed of trust, loan or credit agreement, note, lease 
    or other agreement or instrument to which the Company or any of its 
    subsidiaries is a party or which it or any of them may be bound or to 
    which any property or assets of the Company or any of its subsidiaries is 
    subject (except for such conflicts, breaches, defaults, events or liens, 
    charges or encumbrances that would not result in a Material Adverse 
    Effect) nor will such action result in any violation of the provisions of 
    the declaration of trust, partnership agreement, charter, by-laws, or 
    other organizational documents of the Company or any of its subsidiaries 
    or any applicable law, statute, rule, regulation, judgment, order, writ 
    or decree of any government, government instrumentality or court, 
    domestic or foreign, having jurisdiction over the Company or any if its 
    subsidiaries or any of their assets, properties or operations.

        (15)  There is not pending or threatened any action, suit, 
    proceeding, inquiry or investigation before or brought by any court or 
    governmental agency or body, domestic or foreign, now pending, or to the 
    knowledge of the Company threatened, against or affecting the Company or 
    any of its subsidiaries which is required to be disclosed in the 
    Registration Statement and the Prospectus (other than as stated therein), 
    or which might reasonably be expected to result in a Material Adverse 
    Effect, or which might reasonably be expected to materially and adversely 
    affect the assets, properties or operations thereof or the consummation 
    of the transactions contemplated under this Underwriting Agreement, the 
    applicable Terms Agreement or any applicable Indenture or the performance 
    by the Company of its obligations hereunder and thereunder.  The 
    aggregate of all pending legal or governmental proceedings to which the 
    Company or any of its subsidiaries is a party or of which any of their 
    respective assets, properties or operations is the subject which are not 
    described in the Registration Statement and the Prospectus, including 
    ordinary routine litigation incidental to the business, could not 
    reasonably be expected to result in a Material Adverse Effect.

        (16)  There are no contracts or documents which are required to be 
    described in the Registration Statement, the Prospectus or the documents 
    incorporated by reference therein or to be filed as exhibits thereto 
    which have not been so described and filed as required.

                                   -8-

<PAGE>

        (17)  Each approval, consent, order, authorization, designation, 
    declaration or filing by or with any regulatory, administrative or other 
    governmental body necessary in connection with the execution and delivery 
    by the Company of this Underwriting Agreement, the applicable Terms 
    Agreement and any applicable Indenture and the consummation of the 
    transactions herein and therein contemplated (except such additional 
    steps as may be necessary to qualify the Underwritten Securities for 
    public offering by the Underwriters under state securities or Blue Sky 
    laws) has been obtained or made and is in full force and effect.

        (18)  The Company and its subsidiaries hold all licenses, 
    certificates and permits from governmental authorities which are 
    necessary to the conduct of their business the absence of which would 
    result in a Material Adverse Effect; and neither the Company nor any 
    subsidiary has infringed any patents, patent rights, trade names, 
    trademarks or copyrights, which infringement would result in a Material 
    Adverse Effect.

        (19)  With respect to all tax periods regarding which the Internal 
    Revenue Service is or will be entitled to assert any claim, the Company 
    has met the requirements for qualification as a real estate investment 
    trust under Sections 856 through 860 of the Internal Revenue Code, as 
    amended, and the Company's present and contemplated operations, assets 
    and income continue to meet such requirements.

        (20)  The Company and its subsidiaries have good and marketable title 
    to, or valid and enforceable leasehold estates in, all items of real and 
    personal property referred to in the Prospectus as owned or leased by 
    them, in each case free and clear of all liens, encumbrances, claims, 
    security interests and defects, other than those referred to in the 
    Prospectus or which are not material in amount.  The Company has no 
    reason to believe that the lessee under any lease (excluding leases for 
    which rent payments due for the remainder of such lease are less than 
    $500,000) calling for annual lease payments in excess of $500,000 is not 
    financially capable of performing its obligations thereunder.

        (21)  The Company has filed all Federal, State and foreign income tax 
    returns which have been required to be filed and has paid all taxes 
    indicated by said returns and all assessments received by it to the 
    extent that such taxes have become due.

        (22)  The Underwritten Securities, upon issuance, will be excluded or 
    exempted under, or beyond the purview of, the Commodity Exchange Act, as 
    amended (the "Commodity Exchange Act"), and the rules and regulations 
    of the Commodity Futures Trading Commission under the Commodity Exchange 
    Act (the "Commodity Exchange Act Regulations").

        (23)  The Company is not, and upon the issuance and sale of the 
    Underwritten Securities as herein contemplated and the application of the 
    net proceeds therefrom as described in the 

                                  -9-

<PAGE>

    Prospectus will not be, an "investment company" within the meaning of the 
    Investment Company Act of 1940, as amended (the "1940 Act").

       (24)  The Company has no knowledge of (a) the unlawful presence of any 
    hazardous substances, hazardous materials, toxic substances or waste 
    materials (collectively, "Hazardous Materials") on any of the properties 
    owned by it or any of its subsidiaries, or of (b) any unlawful spills, 
    releases, discharges or disposal of Hazardous Materials that have 
    occurred or are presently occurring off such properties as a result of 
    any construction on or operation and use of such properties which 
    presence or occurrence, singly or in the aggregate, would result in a 
    Material Adverse Effect.  In connection with the construction on or 
    operation and the use of the properties owned by the Company and its 
    subsidiaries, the Company represents that, as of the date of this 
    Underwriting Agreement and will represent that, as of the date of the 
    applicable Terms Agreement, it has no knowledge of any failure to comply 
    with all applicable local, state and federal environmental laws, 
    regulations, ordinances and administrative and judicial orders relating 
    to the generation, recycling, reuse, sale, storage, handling, transport 
    and disposal of any Hazardous Materials which failure would result in a 
    Material Adverse Effect.

       (25)  The Company has complied with, and is and will be in compliance 
    with, the provisions of that certain Florida act relating to disclosure 
    of doing business with Cuba, codified as Section 517.075 of the Florida 
    statutes, and the rules and regulations thereunder or is exempt therefrom.

(b) Any certificate signed by any officer of the Company or any of its 
subsidiaries and delivered to any Underwriter or to counsel for the 
Underwriters in connection with the offering of the Underwritten Securities 
shall be deemed a representation and warranty by the Company to each 
Underwriter as to the matters covered thereby on the date of such certificate 
and, unless subsequently amended or supplemented, at each Representation Date 
subsequent thereto.

    SECTION 2.  Sale and Delivery to Underwriters; Closing.

    (a) The several commitments of the Underwriters to purchase the 
Underwritten Securities pursuant to the applicable Terms Agreement shall be 
deemed to have been made on the basis of the representations and warranties 
herein contained and shall be subject to the terms and conditions herein set 
forth.

    (b) In addition, subject to the terms and conditions herein set forth, 
the Company may grant, if so provided in the applicable Terms Agreement, an 
option to the Underwriters, severally and not jointly, to purchase up to the 
aggregate principal amount of the Option Underwritten Securities set forth 
therein at a price per Option Underwritten Security equal to the price per 
Initial Underwritten Security.  Such option, if granted, will expire 30 days 
after the date of such Terms Agreement, and may be exercised in whole or in 
part from time to time only for the purpose of covering over-allotments which 
may be made in connection with the offering and distribution of the Initial 

                                  -10-

<PAGE>

Underwritten Securities upon notice by you to the Company setting forth the 
aggregate principal amount of Option Underwritten Securities as to which the 
several Underwriters are then exercising the option and the time, date and 
place of payment and delivery for such Option Underwritten Securities.  Any 
such time and date of payment and delivery (each, a "Date of Delivery") shall 
be determined by you, but shall not be later than seven full business days 
after the exercise of said option, nor in any event prior to the Closing 
Time, unless otherwise agreed upon by you and the Company.  If the option is 
exercised as to all or any portion of the Option Underwritten Securities, 
each of the Underwriters, acting severally and not jointly, will purchase 
that proportion of the aggregate principal amount of Option Underwritten 
Securities then being purchased which the aggregate principal amount of 
Initial Underwritten Securities each such Underwriter has severally agreed to 
purchase as set forth in such Terms Agreement bears to the aggregate 
principal amount of Initial Underwritten Securities.

    (c) Payment of the purchase price for, and delivery of, the Initial 
Underwritten Securities shall be made at the offices of Andrews & Kurth 
L.L.P., 1701 Pennsylvania Avenue, N.W., Washington, D.C.  20006, or at such 
other place as shall be agreed upon by you and the Company, at 10:00 A.M. 
(Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. 
(Eastern time) on any given day) business day after the date of the 
applicable Terms Agreement (unless postponed in accordance with the 
provisions of Section 10 hereof), or such other time not later than ten 
business days after such date as shall be agreed upon by you and the Company 
(such time and date of payment and delivery being herein called "Closing 
Time").  In addition, in the event that the Underwriters have exercised their 
option, if any, to purchase any or all of the Option Underwritten Securities, 
payment of the purchase price for, and delivery of such Option Underwritten 
Securities, shall be made at the above-mentioned offices of Andrews & Kurth 
L.L.P., or at such other place as shall be agreed upon by you and the 
Company, on the relevant Date of Delivery as specified in the notice from you 
to the Company.

    Payment shall be made to the Company by wire transfer of immediately 
available funds to a bank account designated by the Company, against delivery 
to you for the respective accounts of the Underwriters of the Underwritten 
Securities to be purchased by them.  It is understood that each Underwriter 
has authorized you, for its account, to accept delivery of, receipt for, and 
make payment of the purchase price for, the Underwritten Securities which it 
has severally agreed to purchase. You, individually and not as representative 
of the Underwriters, may (but shall not be obligated to) make payment of the 
purchase price for the Underwritten Securities to be purchased by any 
Underwriter whose funds have not been received by the Closing Time or the 
relevant Date of Delivery, as the case may be, but such payment shall not 
relieve such Underwriter from its obligations hereunder.

    (d) The Underwritten Securities shall be in such denominations and 
registered in such names as you may request in writing at least one full 
business day prior to the Closing Time or the relevant Date of Delivery, as 
the case may be.  The Underwritten Securities, which may be in temporary 
form, will be made available for examination and packaging by you in The City 
of New York not 

                                   -11-

Time or the relevant Date of Delivery, as the case may be.

    SECTION 3.  Covenants of the Company.  The Company covenants with you and 
with each Underwriter participating in the offering of Underwritten 
Securities, as follows:

        (a)  The Company will comply with the requirements of Rule 434 of the 
    1933 Act Regulations, if and as applicable, and will notify the 
    Representative(s) immediately, and confirm the notice in writing, of (i) 
    the effectiveness of any post-effective amendment to the Registration 
    Statement or the filing of any supplement or amendment to the Prospectus, 
    (ii) the receipt of any comments from the Commission, (iii) any request 
    by the Commission for any amendment to the Registration Statement or any 
    amendment or supplement to the Prospectus or for additional information, 
    and (iv) the issuance by the Commission of any stop order suspending the 
    effectiveness of the Registration Statement or of any order preventing or 
    suspending the use of any preliminary prospectus, or of the suspension of 
    the qualification of the Underwritten Securities for offering or sale in 
    any jurisdiction, or of the initiation or threatening of any proceedings 
    for any of such purposes.  The Company will promptly effect the filings 
    necessary pursuant to Rule 424 and will take such steps as it deems 
    necessary to ascertain promptly whether the Prospectus transmitted for 
    filing under Rule 424 was received for filing by the Commission and, in 
    the event that it was not, it will promptly file the Prospectus.  The 
    Company will make every reasonable effort to prevent the issuance of any 
    stop order and, if any stop order is issued, to obtain the lifting 
    thereof at the earliest possible moment.

        (b)  The Company will give you notice of its intention to file or 
    prepare any amendment to the Registration Statement (including any filing 
    under Rule 462(b) of the 1933 Act Regulations), any Term Sheet or any 
    amendment, supplement or revision to either the prospectus included in 
    the Registration Statement at the time it became effective or to the 
    Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, 
    will furnish you with copies of any such documents a reasonable amount of 
    time prior to such proposed filing or use, as the case may be, and will 
    not file or use any such document to which you or counsel for the 
    Underwriters shall object.

        (c)  The Company has furnished or will deliver to you and counsel for 
    the Underwriters, without charge, signed copies of the Registration 
    Statement as originally filed and of each amendment thereto (including 
    exhibits filed therewith or incorporated by reference therein and 
    documents incorporated or deemed to be incorporated by reference therein) 
    and signed copies of all consents and certificates of experts, and will 
    also deliver to you, without charge, a conformed copy of the Registration 
    Statement as originally filed and of each amendment thereto (without 
    exhibits) for each of the Underwriters. Copies of the Registration 
    Statement and each amendment thereto furnished to the Underwriters will 
    be identical to any electronically transmitted copies thereof filed with 
    the Commission pursuant to EDGAR, except to the extent permitted by 
    Regulation S-T.

                                   -12-

        (d)  The Company will deliver to each Underwriter, without charge, as 
    many copies of each preliminary prospectus as such Underwriter may 
    reasonably request, and the Company hereby consents to the use of such 
    copies for purposes permitted by the 1933 Act.  The Company will furnish 
    to each Underwriter, without charge, during the period when the 
    Prospectus is required to be delivered under the 1933 Act or the 1934 
    Act, such number of copies of the Prospectus as such Underwriter may 
    reasonably request.  The Prospectus and any amendments or supplements 
    thereto furnished to the Underwriters will be identical to any 
    electronically transmitted copies thereof filed with the Commission 
    pursuant to EDGAR, except to the extent permitted by Regulation S-T.

        (e)  The Company will comply with the 1933 Act and the 1933 Act 
    Regulations and the 1934 Act and the 1934 Act Regulations so as to permit 
    the completion of the distribution of the Underwritten Securities as 
    contemplated in this Underwriting Agreement and the applicable Terms 
    Agreement and in the Registration Statement and the Prospectus.  If at 
    any time when the Prospectus is required by the 1933 Act or the 1934 Act 
    to be delivered in connection with sales of the Underwritten Securities, 
    any event shall occur or condition shall exist as a result of which it is 
    necessary, in the opinion of counsel for the Underwriters or for the 
    Company, to amend the Registration Statement in order that the 
    Registration Statement will not 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 or to amend or 
    supplement the Prospectus in order that the Prospectus will not include 
    an untrue statement of a material fact or omit to state a material fact 
    necessary in order to make the statements therein not misleading in the 
    light of the circumstances existing at the time it is delivered to a 
    purchaser, or if it shall be necessary, in the opinion of such counsel, 
    at any such time to amend the Registration Statement or amend or 
    supplement the Prospectus in order to comply with the requirements of the 
    1933 Act or the 1933 Act Regulations, the Company will promptly prepare 
    and file with the Commission, subject to Section 3(b), such amendment or 
    supplement as may be necessary to correct such statement or omission or 
    to make the Registration Statement or the Prospectus comply with such 
    requirements, and the Company will furnish to the Underwriters, without 
    charge, such number of copies of such amendment or supplement as the 
    Underwriters may reasonably request.

        (f)  The Company will use its best efforts, in cooperation with the 
    Underwriters, to qualify the Underwritten Securities and any related 
    Underlying Securities for offering and sale under the applicable 
    securities laws of such states and other jurisdictions (domestic or 
    foreign) as you may designate and to maintain such qualifications in 
    effect for a period of not less than one year from the date of the 
    applicable Terms Agreement; provided, however, that the Company shall not 
    be obligated to file any general consent to service of process or to 
    qualify as a foreign corporation or as a dealer in securities in any 
    jurisdiction in which it is not so qualified or to subject itself to 
    taxation in respect of doing business in any jurisdiction in which it is 
    not otherwise so subject.  In each jurisdiction in which the Underwritten 
    Securities or any related Underlying Securities have been so qualified, 
    the Company will file such statements and reports as may be required by 
    the laws of such jurisdiction to continue 

                                   -13-

<PAGE>

    such qualification in effect for a period of not less than one year from 
    the date of such Terms Agreement.

        (g)  The Company will timely file such reports pursuant to the 1934 
    Act as are necessary in order to make generally available to its security 
    holders as soon as practicable an earnings statement for the purposes of, 
    and to provide the benefits contemplated by, the last paragraph of 
    Section 11(a) of the 1933 Act.

        (h)  The Company will reserve and keep available at all times, free 
    of preemptive or other similar rights, a sufficient number of Common 
    Shares and/or Preferred Shares, as applicable, for the purpose of 
    enabling the Company to satisfy any obligations to issue such Underlying 
    Securities upon conversion of the Senior Debt Securities or Subordinated 
    Debt Securities, as applicable.

      (i)  The Company will use the net proceeds received by it from the sale 
    of the Underwritten Securities in the manner specified in the Prospectus 
    under "Use of Proceeds".

      (j)  The Company will use its best efforts to effect the listing of the 
    Underwritten Securities and any related Underlying Securities, prior to 
    the Closing Time, on any national securities exchange or quotation system 
    if and as specified in the applicable Terms Agreement.

      (k)  Between the date of the applicable Terms Agreement and the Closing 
    Time or such other date specified in such Terms Agreement, the Company 
    will not, without your prior written consent, directly or indirectly, 
    issue, sell, offer to sell, grant any option for the sale of, or 
    otherwise dispose of, the securities specified in such Terms Agreement.

      (l)  The Company, during the period when the Prospectus is required to 
    be delivered under the 1933 Act or the 1934 Act, will file all documents 
    required to be filed with the Commission pursuant to the 1934 Act within 
    the time periods required by the 1934 Act and the 1934 Act Regulations.

    (m) The Company will elect to qualify as a "real estate investment trust" 
    under the Internal Revenue Code of 1986, as amended, and will use its 
    best efforts to continue to meet the requirements to qualify as a "real 
    estate investment trust".

    SECTION 4.  Payment of Expenses. (a) The Company will pay all expenses 
incident to the performance of its obligations under this Underwriting 
Agreement and the applicable Terms Agreement, including (i) the preparation, 
printing and filing of the Registration Statement (including financial 
statements and exhibits) as originally filed and of each amendment thereto, 
(ii) the preparation, printing and delivery to the Underwriters of this 
Underwriting Agreement, any Terms Agreement, any Agreement among 
Underwriters, the Indentures and such other documents as may be required in

    (b) If the applicable Terms Agreement is terminated by you in accordance 
with the provisions of Section 5 or Section 9(b)(i) hereof, the Company shall 
reimburse the Underwriters for all of their out-of-pocket expenses, including 
the reasonable fees and disbursements of counsel for the Underwriters.

    SECTION 5.  Conditions of Underwriters' Obligations.  The obligations of

delivered pursuant to the provisions hereof, to the performance by the 
Company of its covenants and other obligations hereunder, and to the 
following further conditions:

<PAGE>

              (1)  The favorable opinion, dated as of Closing Time, of Arent 
         Fox Kintner Plotkin & Kahn, counsel for the Company, in form and 
         substance satisfactory to counsel for the Underwriters, to the 
         effect that:

                   (i)  The Company has been duly organized and is validly 
              existing as a real estate investment trust in good standing 
              under the laws of the State of Maryland, with trust power and 
              authority to own, lease and operate its properties and conduct 
              its business as described in the Prospectus and to enter into 
              and perform its obligations under the Underwriting Agreement 
              and the applicable Terms Agreement; and the conditions for use 
              of a registration statement on Form S-3 have been satisfied.

                   (ii) The Company is duly qualified to transact business in 
              each jurisdiction in which such qualification is required, 
              whether by reason of the ownership or leasing of property or 
              the conduct of business except where the failure to so qualify 
              would not result in a Material Adverse Effect.

                  (iii) Each Subsidiary has been duly organized and is 
              validly existing as a corporation or partnership, as the case 
              may be, in good standing under the laws of the jurisdiction of 
              its organization and has power and authority to own, lease and 
              operate its properties and to conduct its business as described 
              in the Prospectus.  Except as otherwise stated in the 
              Registration Statement and the Prospectus, all of the issued 
              and outstanding capital stock or other ownership interests of 
              each Subsidiary have been duly authorized and are validly 
              issued, are fully paid and non-assessable and, to the best of 
              the knowledge of such counsel, are owned by the Company, 
              directly or through subsidiaries, free and clear of any 
              security interest, mortgage, pledge, lien, encumbrance, claim 
              or equity.

                  (iv)  Each Subsidiary of the Company is duly qualified as a 
              foreign corporation to transact business and is in good 
              standing in each jurisdiction which such qualification is 
              required, whether by reason of the ownership or leasing of 
              property or the conduct of business, except where the failure 
              to so qualify or be in good standing would not result in a 
              Material Adverse Effect.

                   (v)  The authorized, issued and outstanding shares of 
              beneficial interest of the Company are as set forth in the 
              Prospectus under the caption "Capitalization" (except for 
              subsequent issuances thereof, if any, contemplated under the 
              Underwriting Agreement, pursuant to dividend reinvestment 
              plans, reservations, agreements or employee benefit plans 
              referred to in the Prospectus or pursuant to the exercise of 
              convertible securities or options referred to in the 
              Prospectus).  Such shares of beneficial interest have been duly 
              authorized and validly issued by the Company and are 

                                   -16-

<PAGE>

              fully paid and non-assessable, and none of such shares of 
              beneficial interest was issued in violation of preemptive or 
              other similar rights arising by operation of law or, to the 
              best of their knowledge and information, otherwise.

                   (vi)  The Underwriting Agreement and the applicable Terms 
              Agreement have been duly authorized, executed and delivered by 
              the Company.

                (vii) The Underwritten Securities have been duly authorized 
              by the Company for issuance and sale pursuant to the 
              Underwriting Agreement and the applicable Terms Agreement.  The 
              Underwritten Securities, when issued and authenticated in the 
              manner provided for in the applicable Indenture and delivered 
              against payment of the consideration therefor specified in such 
              Terms Agreement, will constitute valid and legally binding 
              obligations of the Company, enforceable against the Company in 
              accordance with their terms, except as the enforcement thereof 
              may be limited by bankruptcy, insolvency, reorganization, 
              moratorium or other similar laws relating to or affecting 
              creditors' rights generally or by general equitable principles, 
              and except further as enforcement thereof may be limited by (A) 
              requirements that a claim with respect to any Debt Securities 
              denominated other than in U.S. dollars (or a foreign or 
              composite currency judgement in respect of such claim) be 
              converted into U.S. dollars at a rate of exchange prevailing on 
              a date determined pursuant to applicable law or (B) 
              governmental authority to limit, delay or prohibit the making 
              of payments outside the United States.  The Underwritten 
              Securities are in the form contemplated by, and each registered 
              holder thereof is entitled to the benefits of, the applicable 
              Indenture.

                 (viii) The applicable Indenture has been duly authorized, 
              executed and delivered by the Company and (assuming due 
              authorization, execution and delivery thereof by the applicable 
              Indenture Trustee) constitutes a valid and legally binding 
              agreement of the Company, enforceable against the Company in 
              accordance with its terms, except as the enforcement thereof 
              may be limited by bankruptcy, insolvency, reorganization, 
              moratorium or other similar laws relating to or affecting 
              creditors' rights generally or by general equitable principles.

                  (ix)  If applicable, the Underlying Securities have been 
              duly authorized and reserved for issuance by the Company upon 
              conversion of the related Senior Debt Securities or 
              Subordinated Debt Securities. The Underlying Securities, when 
              issued upon such conversion, will be validly issued, fully paid 
              and non-assessable and will not be subject to preemptive or 
              other similar rights 

                                   -17-

<PAGE>

              arising by operation of law or, to the best of their knowledge 
              and information, otherwise.

                  (x)  The applicable Indenture has been duly qualified 
              under the 1939 Act.

                 (xi) The Underwritten Securities being sold pursuant to the 
              applicable Terms Agreement and the applicable Indenture 
              conform, and any Underlying Securities, when issued and 
              delivered in accordance with the terms of the related 
              Underwritten Securities, will conform, in all material respects 
              to the statements relating thereto contained in the Prospectus 
              and are in substantially the form filed or incorporated by 
              reference, as the case may be, as an exhibit to the 
              Registration Statement.

                   (xii)  The statements in the Prospectus under "Description 
              of Debt Securities", "Description of Shares", "Description of 
              Underlying Securities", if any, and "Certain Federal Income Tax 
              Considerations", if any, and in the Registration Statement 
              under Item 15, insofar as such statements constitute a summary 
              of documents referred to therein or matters of law, are 
              accurate summaries and fairly and correctly present the 
              information called for with respect to such documents and 
              matters in all material respects.

                   (xiii)  Such counsel does not know of any contracts or 
              documents required to be filed as exhibits to or incorporated 
              by reference in the Registration Statement or described in the 
              Registration Statement or the Prospectus which are not so 
              filed, incorporated by reference or described as required, and 
              such contracts and documents as are summarized in the 
              Registration Statement or the Prospectus are fairly summarized 
              in all material respects (except that such counsel need express 
              no opinion as to the financial statements, schedules and other 
              financial information included or incorporated by reference 
              therein).

                  (xiv)  The execution, delivery and performance of the 
              Underwriting Agreement, the applicable Terms Agreement and the 
              applicable Indenture and the consummation of the transactions 
              contemplated therein and compliance by the Company with its 
              obligations thereunder do not constitute a breach of any of the 
              terms or provisions of, or constitute a default under, (a) the 
              declaration of trust, partnership agreement, charter, by-laws, 
              or other organizational document of the Company or any of its 
              subsidiaries, (b) certain specified agreements which are set 
              forth on a schedule to such opinion to which the Company is a 
              party, (c) any order known to such counsel of any court or 
              government agency or body having jurisdiction over the Company 
              or any of its subsidiaries or any of their properties.

                                   -18-

<PAGE>

                 (xv)  To the best of such counsel's knowledge, neither the 
              Company nor any of its subsidiaries is in violation of its 
              declaration of trust, partnership agreement, charter, by-laws 
              or other organizational document.

                 (xvi)  Such counsel knows of no material legal proceedings 
              pending or threatened against the Company.

                 (xvii)  No approval, consent, order, authorization, 
              designation, declaration or filing by or with any regulatory, 
              administrative or other governmental body is necessary in 
              connection with the execution and delivery of the Underwriting 
              Agreement, the applicable Terms Agreement or the applicable 
              Indenture and the consummation of the transactions therein 
              contemplated by the Company (other than as may be required by 
              the NASD or State securities or Blue Sky laws, as to which such 
              counsel need express no opinion) except such as have been 
              obtained or made, specifying the same.

                 (xviii) The investments of the Company described in the 
              Prospectus are permitted investments under its declaration of 
              trust.

                 (xix) The Company has qualified to be taxed as a real estate 
              investment trust pursuant to Sections 856-860 of the Internal 
              Revenue Code, as amended, for the fiscal years ended December 
              31, 1992 through December 31, 1996, and the Company's present 
              method of operation and its assets and contemplated income are 
              such that the Company is in a position under present law to so 
              qualify for the fiscal year ending December 31, 1997, and under 
              the present law the federal income tax treatment of the Company 
              and its shareholders will be as set forth in the Prospectus 
              under the heading "Description of Shares".

                   (xx)  The Registration Statement has been declared 
              effective under the 1933 Act.  Any required filing of the 
              Prospectus pursuant to Rule 424(b) has been made in the manner 
              and within the time period required by Rule 424(b).  To the 
              best of such counsel's knowledge, no stop order suspending the 
              effectiveness of the Registration Statement has been issued 
              under the 1933 Act and no proceedings for that purpose have 
              been initiated or are pending or threatened by the Commission.

                   (xxi)  The Registration Statement and the Prospectus, 
              excluding the documents incorporated by reference therein, and 
              each amendment or supplement to the Registration Statement and 
              Prospectus, excluding the documents incorporated by reference 
              therein, as of their respective effective or issue dates (other 
              than the financial statements and supporting schedules included 
              therein or omitted therefrom and each Indenture Trustee's 
              Statement 

                                   -19-

<PAGE>

              of Eligibility on Form T-1 (the "Form T-1s"), as to which such 
              counsel need express no opinion) complied as to form in all 
              material respects with the requirements of the 1933 Act and the 
              1933 Act Regulations.

                  (xxii)  The documents incorporated by reference in the 
              Prospectus (other than the financial statements and supporting 
              schedules therein or omitted therefrom, as to which such 
              counsel need express no opinion), when they were filed with the 
              Commission, complied as to form in all material respects with 
              the requirements of the 1934 Act and the rules and regulations 
              of the Commission thereunder.

                  (xxiii)  The Underwritten Securities, upon issuance, will 
              be excluded or exempted under, or beyond the purview of, the 
              Commodity Exchange Act and the Commodity Exchange Act 
              Regulations.

                   (xxiv) The Company is not an "investment company" within 
              the meaning of the 1940 Act.

              In rendering such opinion, Arent Fox Kintner Plotkin & Kahn may 
         rely as to matters governed by the laws of jurisdictions other than 
         Maryland and Delaware or Federal laws on local counsel in such 
         jurisdictions, provided that in each case Arent Fox Kintner Plotkin 
         & Kahn shall state that they believe that they and the Underwriters 
         are justified in relying on such other counsel.  In addition to the 
         matters set forth above, such opinion shall also include a statement 
         to the effect that nothing has come to the attention of such counsel 
         which leads them to believe that the Registration Statement, as of 
         the time it became effective under the 1933 Act or at the date of 
         the applicable Terms Agreement, contained an untrue statement of a 
         material fact or omitted to state a material fact required to be 
         stated therein or necessary to make the statements therein not 
         misleading or that the Prospectus, at the date of the applicable 
         Terms Agreement or at Closing Time, contained or contains an untrue 
         statement of a material fact or omitted or omits 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 
         (except that such counsel need express no view as to financial 
         statements, schedules and other financial information included or 
         incorporated by reference therein).  With respect to such statement, 
         Arent Fox Kintner Plotkin & Kahn may state that their belief is 
         based upon the procedures set forth therein, but is without 
         independent check and verification.

              (2)  The favorable opinion, dated as of Closing Time, of 
         Andrews & Kurth L.L.P., counsel for the Underwriters, with respect 
         to the matters set forth in (vi), (vii), (viii), (ix), (x), (xi), 
         (xii) (only with respect to the statements set forth under 
         "Description of Debt Securities" and "Description of Underlying 
         Securities", if 

                                   -20-

<PAGE>

         any), (xx) and (xxi) of subsection (b)(l) of this Section.  In 
         addition to the matters set forth above, such opinion shall also 
         include a statement to the effect that nothing has come to the 
         attention of such counsel which leads them to believe that the 
         Registration Statement, as of the time it became effective under the 
         1933 Act or at the date of the applicable Terms Agreement, contained 
         an untrue statement of a material fact or omitted to state a 
         material fact required to be stated therein or necessary to make the 
         statements therein not misleading or that the Prospectus, at the 
         date of the applicable Terms Agreement or at Closing Time, contained 
         or contains an untrue statement of a material fact or omitted or 
         omits 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 (except that such counsel need 
         express no view as to financial statements, schedules and other 
         financial information included or incorporated by reference 
         therein). With respect to such statement, Andrews & Kurth L.L.P. may 
         state that their belief is based upon the procedures set forth 
         therein, but is without independent check and verification.

        (c)  At Closing Time, there shall not have been, since the date of 
    the applicable Terms Agreement or since the respective dates as of which 
    information is given in the Prospectus, any material adverse change in 
    the condition, financial or otherwise, or in the earnings, business 
    affairs or business prospects of the Company and its subsidiaries 
    considered as one enterprise, whether or not arising in the ordinary 
    course of business, and you shall have received a certificate of the 
    President or a Vice President of the Company and of the chief financial 
    officer or chief accounting officer of the Company, dated as of Closing 
    Time, to the effect that (i) there has been no such material adverse 
    change, (ii) the representations and warranties in Section 1 are true and 
    correct with the same force and effect as though expressly made at and as 
    of the Closing Time, (iii) the Company has complied with all agreements 
    and satisfied all conditions on its part to be performed or satisfied at 
    or prior to the Closing Time, and (iv) no stop order suspending the 
    effectiveness of the Registration Statement has been issued and no 
    proceedings for that purpose have been initiated or threatened by the 
    Commission.

        (d)  At the time of the execution of the applicable Terms Agreement, 
    you shall have received from Arthur Andersen LLP a letter dated such 
    date, in form and substance satisfactory to you, to the effect that (i) 
    they are independent public accountants with respect to the Company and 
    its subsidiaries as required by the 1933 Act and the 1934 Act and the 
    applicable published rules and regulations thereunder; (ii) it is their 
    opinion that the consolidated financial statements and supporting 
    schedules of the Company and its subsidiaries included or incorporated by 
    reference in the Registration Statement and covered by their opinions 
    therein comply as to form in all material respects with the applicable 
    accounting requirements of the 1933 Act and the 1934 Act and the related 
    published rules and regulations thereunder; (iii) based upon limited 
    procedures set forth in detail in such letter (which shall include, 
    without limitation, the procedures specified 

                                   -21-

    by the American Institute of Certified Public Accountants for a review of 
    interim financial information as described in SAS No. 71, Interim 
    Financial Information, with respect to the unaudited condensed 
    consolidated financial statements of the Company and its subsidiaries 
    included or incorporated by reference in the Registration Statement), 
    nothing has come to their attention which causes them to believe that:

             (1)  any material modifications should be made to the unaudited 
         condensed consolidated financial statements included or incorporated 
         by reference in the Registration Statement for them to be in 
         conformity with generally accepted accounting principles;

             (2)  the unaudited condensed consolidated financial statements 
         included or incorporated by reference in the Registration Statement 
         do not comply as to form in all material respects with the 
         applicable accounting requirements of the 1933 Act and the 1934 Act 
         as it applies to Form 10-Q and the related published rules and 
         regulations;

              (3)  at a specified date not more than three days prior to the 
         date of such letter, there was any change in the capitalization of 
         the Company and its subsidiaries, any decrease in total assets, any 
         change in long-term debt or any change in short-term borrowings of 
         the Company and its subsidiaries, as compared with the amounts shown 
         in the most recent consolidated balance sheet incorporated by 
         reference in the Registration Statement; or

             (4)  during the period from the date of the most recent 
         consolidated balance sheet incorporated by reference in the 
         Registration Statement to a specified date not more than three days 
         prior to the date of such letter, there were any decreases, as 
         compared with the corresponding period in the preceding year, in 
         real estate rental revenue, net income or net income per share of 
         the Company and its subsidiaries;

    except in all cases for changes, increases or decreases which the 
    Registration Statement discloses have occurred or may occur; (iv) in 
    addition to the limited procedures referred to in clause (iii) above, 
    they have carried out certain specified procedures, not constituting an 
    audit, with respect to certain amounts, percentages and financial 
    information which are derived from the general accounting records of the 
    Company and its subsidiaries, which are included or incorporated by 
    reference in the Registration Statement and which are specified by you, 
    and have compared such amounts, percentages and financial information 
    with the accounting records of the Company and its subsidiaries and have 
    found them to be in agreement; and (v) they have compared the information 
    in the Prospectus under the caption "Selected Financial Data" with the 
    disclosure requirements of Regulation S-K and on the basis of limited 
    procedures specified in such letter nothing came to their attention as a 
    result of the foregoing procedures that caused them to believe that this 
    information 

                                   -22-
<PAGE>

    does not conform in all material respects with the disclosure 
    requirements of Item 301 of Regulation S-K.

        (e)  At Closing Time, you shall have received from Arthur Andersen 
    LLP a letter, dated as of Closing Time, to the effect that they reaffirm 
    the statements made in the letter furnished pursuant to subsection (d) of 
    this Section 5, except that the specified date referred to shall be a 
    date not more than three business days prior to the Closing Time.

        (f) At the time of the execution of the applicable Terms Agreement, 
    you shall have received from Price Waterhouse L.L.P. a letter dated such 
    date, in form and substance satisfactory to you, to the effect that (i) 
    they are independent public accountants with respect to the Company and 
    its subsidiaries as required by the 1933 Act and the 1934 Act and the 
    applicable published rules and regulations thereunder; and (ii) it is 
    their opinion that the consolidated financial statements and supporting 
    schedules of the Company and its subsidiaries included or incorporated by 
    reference in the Registration Statement and covered by their opinions 
    therein comply as to form in all material respects with the applicable 
    accounting requirements of the 1933 Act and the 1934 Act and the related 
    published rules and regulations thereunder.

        (g) If applicable, at the time of the execution of the applicable 
    Terms Agreement, you  shall have received a letter dated such date from 
    such independent accountants that have prepared any historical financial 
    statements included in or incorporated by referenced into the 
    Registration Statement and Prospectus which financial statements relate 
    to properties or assets acquired or to be acquired by the Company, or any 
    of its subsidiaries, in form and substance satisfactory to the 
    Underwriters, to the effect that (i) they are independent accountants 
    with respect to the Company and such properties or assets acquired by the 
    Company within the meaning of the 1933 Act and the 1933 Act Regulations; 
    and (ii) it is their opinion that the historical financial statements for 
    such properties or assets that have been audited by them and covered by 
    their opinions included or incorporated by reference into the 
    Registration Statement and the Prospectus comply in form in all material 
    respects with the applicable accounting requirements of the 1933 Act and 
    the 1933 Act Regulations.

        (h)  At Closing Time and at any relevant Date of Delivery, the 
    Underwritten Securities shall have the ratings accorded by any 
    "nationally recognized statistical rating organization", as defined by 
    the Commission for purposes of Rule 436(g)(2) of the 1933 Act 
    Regulations, if and as specified in the applicable Terms Agreement, and 
    the Company shall have delivered to you a letter, dated as of such date, 
    from each such rating organization, or other evidence satisfactory to 
    you, confirming that the Underwritten Securities have such ratings.  
    Since the time of execution of such Terms Agreement, there shall not have 
    occurred a downgrading in the rating assigned to the Underwritten 
    Securities or any of the Company's other securities by any such rating 
    organization, and no such rating organization shall have publicly 
    announced that it has under surveillance or review its rating of the 
    Underwritten Securities or any of the Company's other securities.

                                   -23-

        (i)  At Closing Time, the Underwritten Securities shall have been 
    approved for listing, subject only to official notice of issuance, if and 
    as specified in the applicable Terms Agreement.

        (j) On the date of the applicable Terms Agreement, you shall have 
    received, in form and substance satisfactory to you, each lock-up 
    agreement, if any, specified in such Terms Agreement as being required to 
    be delivered by the persons listed therein.

        (k)  In the event that the Underwriters are granted an over-allotment 
    option by the Company in the applicable Terms Agreement and the 
    Underwriters exercise their option to purchase all or any portion of the 
    Option Underwritten Securities, the representations and warranties of the 
    Company contained herein and the statements in any certificates furnished 
    by the Company or any of its subsidiaries hereunder shall be true and 
    correct as of each Date of Delivery, and, at the relevant Date of 
    Delivery, you shall have received:

             (1)  A certificate, dated such Date of Delivery, of the 
         President or a Vice President of the Company and the chief financial 
         officer or chief accounting officer of the Company, confirming that

         counsel for the Company, in form and substance satisfactory to 
         counsel for the Underwriters, dated such Date of Delivery, relating 
         to the Option Underwritten Securities and otherwise to the same 
         effect as the opinion required by Section 5(b)(1) hereof.

             (3) The favorable opinion of Andrews & Kurth L.L.P., counsel for 
         the Underwriters, dated such Date of Delivery, relating to the 
         Option Underwritten Securities and otherwise to the same effect as 
         the opinion required by Section 5(b)(2) hereof.

         the letter furnished pursuant to this paragraph shall be a date not

        (l)  At Closing Time and at each Date of Delivery, counsel for the 
    Underwriters shall have been furnished with such documents and opinions 
    as they may require for the purpose of enabling them to pass upon the 
    issuance and sale of the Underwritten Securities as herein contemplated, 
    or in order to evidence the accuracy of any of the representations or 
    warranties, or the fulfillment of any of the conditions, herein 
    contained; and all proceedings taken by the Company in connection with 
    the issuance and sale of the Underwritten 

                                   -24-

<PAGE>

    Securities as herein contemplated shall be satisfactory in form and 
    substance to you and counsel for the Underwriters.

        (m)  If any condition specified in this Section 5 shall not have been 
    fulfilled when and as required to be fulfilled, the applicable Terms 
    Agreement (or, with respect to the Underwriters' exercise of any 
    applicable over-allotment option for the purchase of Option Underwritten 
    Securities on a Date of Delivery after the Closing Time, the obligations 
    of the Underwriters to purchase the Option Underwritten Securities on 
    such Date of Delivery) may be terminated by you by notice to the Company 
    at any time at or prior to the Closing Time (or such Date of Delivery, as 
    applicable), and such termination shall be without liability of any party 
    to any other party except as provided in Section 4 and except that 
    Sections 1, 6, 7 and 8 shall survive any such termination and remain in 
    full force and effect.

    SECTION 6.  Indemnification.

    (a) The Company hereby agrees to indemnify and hold harmless each 
Underwriter and each person, if any, who controls any Underwriter within the 
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as 
follows:

        (1)  against any and all loss, liability, claim, damage and expense 
    whatsoever, as incurred, arising out of any untrue statement or alleged 
    untrue statement of a material fact contained in the Registration 
    Statement (or any amendment thereto), including the Rule 434 Information 
    deemed to be a part thereof, if applicable, or the omission or alleged 
    omission therefrom of a material fact required to be stated therein or 
    necessary to make the statements therein not misleading or arising out of 
    any untrue statement or alleged untrue statement of a material fact 
    included in any preliminary prospectus or the Prospectus (or any 
    amendment or supplement thereto), or the omission or alleged omission 
    therefrom of a material fact necessary in order to make the statements 
    therein, in the light of the circumstances under which they were made, 
    not misleading;

        (2)  against any and all loss, liability, claim, damage and expense 
    whatsoever, as incurred, to the extent of the aggregate amount paid in 
    settlement of any litigation, or any investigation or proceeding by any 
    governmental agency or body, commenced or threatened, or of any claim 
    whatsoever based upon any such untrue statement or omission, or any such 
    alleged untrue statement or omission; provided that any such settlement 
    is effected with the written consent of the Company; and

        (3)  against any and all expense whatsoever, as incurred (including, 
    subject to Section 6(c) hereof, the fees and disbursements of counsel 
    chosen by you), reasonably incurred in investigating, preparing or 
    defending against any litigation, or any investigation or proceeding by 
    any governmental agency or body, commenced or threatened, or any claim 
    whatsoever based upon any such untrue statement or omission, or any such 
    alleged untrue statement or omission, to the extent that any such expense 
    is not paid under (i) or (ii) above;

                                   -25-

<PAGE>

provided, however, that this indemnity agreement shall not apply to any loss, 
liability, claim, damage or expense to the extent arising out of any untrue 
statement or omission or alleged untrue statement or omission made in 
reliance upon and in conformity with written information furnished to the 
Company by any Underwriter through you expressly for use in the Registration 
Statement (or any amendment thereto), including the Rule 434 Information 
deemed to be a part thereof, if applicable, or any preliminary prospectus or 
the Prospectus (or any amendment or supplement thereto).

    (b) Each Underwriter severally agrees to indemnify and hold harmless the 
Company, its trustees, each of its officers who signed the Registration 
Statement, and each person, if any, who controls the Company within the 
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against 
any and all loss, liability, claim, damage and expense described in the 
indemnity contained in subsection (a) of this Section, as incurred, but only 
with respect to untrue statements or omissions, or alleged untrue statements 
or omissions, made in the Registration Statement (or any amendment thereto), 
including the Rule 434 Information deemed to be a part thereof, if 
applicable, or any preliminary prospectus or the Prospectus (or any amendment 
or supplement thereto) in reliance upon and in conformity with written 
information furnished to the Company by such Underwriter through you 
expressly for use in the Registration Statement (or any amendment thereto) or 
such preliminary prospectus or the Prospectus (or any amendment or supplement 
thereto).

    (c) Each indemnified party shall give notice as promptly as reasonably 
practicable to each indemnifying party of any action commenced against it in 
respect of which indemnity may be sought hereunder, but failure to so notify 
an indemnifying party shall not relieve such indemnifying party from any 
liability hereunder to the extent it is not materially prejudiced as a result 
thereof and in any event shall not relieve it from any liability which it may 
have otherwise than on account of this indemnity agreement.  In the case of 
parties indemnified pursuant to Section 6(a) above, counsel to the 
indemnified parties shall be selected by you, and, in the case of parties 
indemnified pursuant to Section 6(b) above, counsel to the indemnified 
parties shall be selected by the Company.  An indemnifying party may 
participate at its own expense in the defense of any such action; provided, 
however, that counsel to the indemnifying party shall not (except with the 
consent of the indemnified party) also be counsel to the indemnified party.  
In no event shall the indemnifying parties be liable for fees and expenses of 
more than one counsel (in addition to any local counsel) separate from their 
own counsel for all indemnified parties in connection with any one action or 
separate but similar or related actions in the same jurisdiction arising out 
of the same general allegations or circumstances.  No indemnifying party 
shall, without the prior written consent of the indemnified parties, settle 
or compromise or consent to the entry of any judgment with respect to any 
litigation, or any investigation or proceeding by any governmental agency or 
body, commenced or threatened, or any claim whatsoever in respect of which 
indemnification or contribution could be sought under this Section 6 or 
Section 7 hereof (whether or not the indemnified parties are actual or 
potential parties thereto), unless such settlement, compromise or consent (i) 
includes an unconditional release of each indemnified party from all 
liability arising out of such litigation, investigation, proceeding or claim 
and (ii) does not include a statement as to or an admission of fault, 
culpability or a failure to act by or on behalf of any indemnified party.

                                   -26-

<PAGE>

         SECTION 7.  Contribution.  If the indemnification provided for in 
Section 6 hereof is for any reason unavailable to or insufficient to hold 
harmless an indemnified party in respect of any losses, liabilities, claims, 
damages or expenses referred to therein, then each indemnifying party shall 
contribute to the aggregate amount of such losses, liabilities, claims, 
damages and expenses incurred by such indemnified party, as incurred, (i) in 
such proportion as is appropriate to reflect the relative benefits received 
by the Company, on the one hand, and the Underwriters, on the other hand, 
from the offering of the Underwritten Securities pursuant to the applicable 
Terms Agreement or (ii) if the allocation provided by clause (i) is not 
permitted by applicable law, in such proportion as is appropriate to reflect 
not only the relative benefits referred to in clause (i) above but also the 
relative fault of the Company, on the one hand, and of the Underwriters, on 
the other hand, in connection with the statements or omissions which resulted 
in such losses, liabilities, claims, damages or expenses, as well as any 
other relevant equitable considerations.

    The relative benefits received by the Company, on the one hand, and the 
Underwriters, on the other hand, in connection with the offering of the 
Underwritten Securities pursuant to the applicable Terms Agreement shall be 
deemed to be in the same respective proportions as the total net proceeds 
from the offering of such Underwritten Securities (before deducting expenses) 
received by the Company and the total underwriting discount received by the 
Underwriters, in each case as set forth on the cover of the Prospectus, or, 
if Rule 434 is used, the corresponding location on the Term Sheet, bear to 
the aggregate initial public offering price of such Underwritten Securities 
as set forth on such cover.

    The relative fault of the Company, on the one hand, and the Underwriters, 
on the other hand, shall be determined by reference to, among other things, 
whether any such untrue or alleged untrue statement of a material fact or 
omission or alleged omission to state a material fact relates to information 
supplied by the Company or by the Underwriters and the parties' relative 
intent, knowledge, access to information and opportunity to correct or 
prevent such statement or omission.

    The Company and the Underwriters agree that it would not be just and 
equitable if contribution pursuant to this Section 7 were determined by pro 
rata allocation (even if the Underwriters 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 above in this Section 7.  The 
aggregate amount of losses, liabilities, claims, damages and expenses 
incurred by an indemnified party and referred to above in this Section 7 
shall be deemed to include any legal or other expenses reasonably incurred by 
such indemnified party in investigating, preparing or defending against any 
litigation, or any investigation or proceeding by any governmental agency or 
body, commenced or threatened, or any claim whatsoever based upon any such 
untrue or alleged untrue statement or omission or alleged omission.

    Notwithstanding the provisions of this Section 7, no Underwriter shall be 
required to contribute any amount in excess of the amount by which the total 
price at which the Underwritten Securities underwritten by it and distributed 
to the public were offered to the public exceeds the 

                                   -27-

<PAGE>

amount of any damages which such Underwriter has otherwise been required to 
pay by reason of any such untrue or alleged untrue statement or omission or 
alleged omission.

    No person guilty of fraudulent misrepresentation (within the meaning of 
Section 11(f) of the 1933 Act) shall be entitled to contribution from any 
person who was not guilty of such fraudulent misrepresentation.

    For purposes of this Section 7, each person, if any, who controls an 
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of 
the 1934 Act shall have the same rights to contribution as such Underwriter, 
and each trustee of the Company, each officer of the Company who signed the 
Registration Statement, and each person, if any, who controls the Company 
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 
Act shall have the same rights to contribution as the Company.  The 
Underwriters' respective obligations to contribute pursuant to this Section 7 
are several in proportion to the aggregate principal amount of Initial 
Underwritten Securities set forth opposite their respective names in the 
applicable Terms Agreement, and not joint.

    SECTION 8.  Representations, Warranties and Agreements to Survive 
Delivery.  All representations, warranties and agreements contained in this 
Underwriting Agreement or the applicable Terms Agreement or in certificates 
of officers of the Company submitted pursuant hereto or thereto shall remain 
operative and in full force and effect, regardless of any investigation made 
by or on behalf of any Underwriter or controlling person, or by or on behalf 
of the Company, and shall survive delivery of and payment for the 
Underwritten Securities.

    SECTION 9.  Termination.

    (a) This Underwriting Agreement (excluding the applicable Terms 
Agreement) may be terminated for any reason at any time by the Company or by 
you upon the giving of 30 days' prior written notice of such termination to 
the other party hereto.

    (b) You may terminate the applicable Terms Agreement, by notice to the 
Company, at any time at or prior to the Closing Time or any relevant Date of 
Delivery, if (i) there has been, since the time of execution of such Terms 
Agreement or since the respective dates as of which information is given in 
the Prospectus, any material adverse change in the condition, financial or 
otherwise, or in the earnings, business affairs or business prospects of the 
Company and its subsidiaries considered as one enterprise, whether or not 
arising in the ordinary course of business, or (ii) there has occurred any 
material adverse change in the financial markets in the United States or, if 
the Underwritten Securities are denominated or payable in, or indexed to, one 
or more foreign or composite currencies, in the international financial 
markets, or any outbreak of hostilities or escalation thereof or other 
calamity or crisis or any change or development involving a prospective 
change in national or international political, financial or economic 
conditions, in each case the effect of which is such as to make it, in your 
judgment, impracticable to market the Underwritten Securities or to enforce 
contracts for the sale of the Underwritten Securities, or (iii) trading in 
any securities of the Company has been suspended or limited by the Commission 
or the American Stock Exchange, or if trading 

                                   -28-

<PAGE>

generally on the New York Stock Exchange or the American Stock Exchange or in 
the Nasdaq National Market has been suspended or limited, or minimum or 
maximum prices for trading have been fixed, or maximum ranges for prices have 
been required, by either of said exchanges or by such system or by order of 
the Commission, the NASD or any other governmental authority, or (iv) a 
banking moratorium has been declared by either Federal or New York 
authorities or, if the Underwritten Securities are denominated or payable in, 
or indexed to, one or more foreign or composite currencies, by the relevant 
authorities in the related foreign country or countries.

    (c) If this Underwriting Agreement or the applicable Terms Agreement is 
terminated pursuant to this Section 9, such termination shall be without 
liability of any party to any other party except as provided in Section 4 
hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such 
termination and remain in full force and effect.

    SECTION 10.  Default by One or More of the Underwriters.  If one or more 
of the Underwriters shall fail at the Closing Time or the relevant Date of 
Delivery, as the case may be, to purchase the Underwritten Securities which 
it or they are obligated to purchase under the applicable Terms Agreement 
(the "Defaulted Securities"), then you shall have the right, within 24 hours 
thereafter, to make arrangements for one or more of the non-defaulting 
Underwriters, or any other underwriters, to purchase all, but not less than 
all, of the Defaulted Securities in such amounts as may be agreed upon and 
upon the terms herein set forth; if, however, you shall not have completed 
such arrangements within such 24-hour period, then:

          (a)   if the aggregate principal amount of Defaulted Securities 
    does not exceed 10% of the aggregate principal amount of Underwritten 
    Securities to be purchased on such date pursuant to such Terms Agreement, 
    the non-defaulting Underwriters shall be obligated, severally and not 
    jointly, to purchase the full amount thereof in the proportions that 
    their respective underwriting obligations under such Terms Agreement bear 
    to the underwriting obligations of all non-defaulting Underwriters, or

        (b)  if the aggregate principal amount of Defaulted Securities 
    exceeds 10% of the aggregate principal amount of Underwritten Securities 
    to be purchased on such date pursuant to such Terms Agreement, such Terms 
    Agreement (or, with respect to the Underwriters' exercise of any 
    applicable over-allotment option for the purchase of Option Underwritten 
    Securities on a Date of Delivery after the Closing Time, the obligations 
    of the Underwriters to purchase, and the Company to sell, such Option 
    Underwritten Securities on such Date of Delivery) shall terminate without 
    liability on the part of any non-defaulting Underwriter.

    No action taken pursuant to this Section 10 shall relieve any defaulting 
Underwriter from liability in respect of its default.

    In the event of any such default which does not result in (i) a 
termination of the applicable Terms Agreement or (ii) in the case of a Date 
of Delivery after the Closing Time, a termination of the obligations of the 
Underwriters and the Company with respect to the related Option Underwritten 

                                   -29-

<PAGE>

Securities, as the case may be, either you or the Company shall have the 
right to postpone the Closing Time or the relevant Date of Delivery, as the 
case may be, for a period not exceeding seven days in order to effect any 
required changes in the Registration Statement or the Prospectus or in any 
other documents or arrangements.

    SECTION 11.  Notices.  All notices and other communications hereunder 
shall be in writing and shall be deemed to have been duly given if mailed or 
transmitted by any standard form of telecommunication.  Notices to the

remedy or claim under or in respect of this Underwriting Agreement or such

shall be deemed to be a successor by reason merely of such purchase.

    SECTION 13.  GOVERNING LAW AND TIME.  THIS UNDERWRITING AGREEMENT AND ANY 
APPLICABLE TERMS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE 
WITH THE LAWS OF THE STATE OF NEW YORK.  EXCEPT AS OTHERWISE SET FORTH

[Name(s) of Representative(s)]

Ladies and Gentlemen:

    Washington Real Estate Investment Trust, a real estate investment trust 
organized under the laws of the State of Maryland (the "Company"), proposes 
to issue and sell (i) its common shares of beneficial interest, par value 
$.01 per share (the "Common Shares"), (ii) warrants to purchase Common Shares 
(the "Common Share Warrants") or (iii) its preferred shares of beneficial 
interest, par value $.01 per share (the "Preferred Shares"), from time to 
time, in one or more offerings on terms to be determined at the time of sale. 

    The Preferred Shares will be issued in one or more series and each series 
of Preferred Shares may vary, as applicable, as to the specific number of 
shares, title, rank, stated value, liquidation preference, dividend rate (or 
method of calculation), dividend payments dates, redemption provisions, 
sinking fund requirements, conversion provisions (and terms of the related 
Underlying Securities (as defined below) and any other variable terms as set 
forth in the applicable amendment to the Company's Declaration of Trust (each 
a "Designating Amendment") relating to such series of Preferred Shares.

    Each issue of Common Share Warrants will be issued pursuant to a separate 
warrant agreement (each, a "Warrant Agreement") between the Company and the 
warrant agent identified 

<PAGE>

therein (each, a "Warrant Agent").  The Common Share Warrants may vary, as 
applicable, as to, among other terms, title, specific number, exercise dates 
or periods, exercise price(s) and expiration date(s).

    As used herein, "Securities" shall mean the Common Shares, Common Share 
Warrants and Preferred Shares, or any combination thereof, initially issuable 
by the Company and "Underlying Securities" shall mean the Common Shares 
issuable upon exercise of the Common Share Warrants or upon conversion of the 
Preferred Shares, as applicable. As used herein, "you" and "your", unless the 
context otherwise requires, shall mean the parties to whom this Agreement is 
addressed together with the other parties, if any, identified in the 
applicable Terms Agreement (as hereinafter defined) as additional co-managers 
with respect to the Underwritten Securities (as hereinafter defined) 
purchased pursuant thereto.

    Whenever the Company determines to make an offering of Securities through 
you or through an underwriting syndicate managed by you, the Company will 
enter into an agreement (each, a "Terms Agreement") providing for the sale of 
such Securities (the "Underwritten Securities") to, and the purchase and 
offering thereof by, you and such other underwriters, if any, selected by you 
(the "Underwriters", which term shall include you, whether acting alone or as 
members of an underwriting syndicate, as well as any Underwriter substituted 
pursuant to Section 10 hereof).  The Terms Agreement relating to the offering 
of Underwritten Securities shall specify the number of Underwritten 
Securities to be initially issued (the "Initial Underwritten Securities"), 
the name of each Underwriter participating in such offering (subject to 
substitution as provided in Section 10 hereof) and the name of each 
additional co-manager, if any, participating in such offering, the number of 
Initial Underwritten Securities which each such Underwriter severally agrees 
to purchase, the price at which the Initial Underwritten Securities are to be 
purchased by the Underwriters and the initial public offering price 
applicable thereto, the form, time, date and place of delivery and payment of 
the Initial Underwritten Securities and any other material variable terms of 
the Initial Underwritten Securities.  In addition, such Terms Agreement shall 
specify whether the Company has agreed to grant to the Underwriters an option 
to purchase additional Securities to cover over-allotments, if any, and the 
number of Securities subject to such option (the "Option Underwritten 
Securities").  As used herein, the term "Underwritten Securities" shall 
include the Initial Underwritten Securities and all or any portion of any 
Option Underwritten Securities.  The Terms Agreement, which shall be 
substantially in the form of Exhibit A hereto, may take the form of an 
exchange of any standard form of written telecommunication between the 
Company and you.  Each offering of Underwritten Securities through you or 
through an underwriting syndicate managed by you will be governed by this 
Underwriting Agreement, as supplemented by the applicable Terms Agreement.

    The Company has filed with the Securities and Exchange Commission (the 
"Commission") a registration statement on Form S-3 (No. 333-_____) 
[and pre-effective amendment no. 1 thereto] for the registration of the 
Securities and the Underlying Securities and certain of the Company's debt 
securities under the Securities Act of 1933, as amended (the "1933 Act"), and 
the offering thereof from time to time in accordance with Rule 415 of the 
rules and regulations of the Commission under the 1933 Act (the "1933 Act 
Regulations"), and the Company has filed such post-effective

                                     -2-

<PAGE>

applicable Terms Agreement.  Such registration statement (as so amended, if 
applicable) has been declared effective by the Commission.  Such registration

Regulations (the "Rule 434 Information"), is referred to herein as the 
"Registration Statement"; and the final prospectus and the final prospectus 
supplement relating to the offering of the Underwritten Securities, in the 
form first furnished to the Underwriters by the Company for use in connection 
with the offering of the Underwritten Securities, are collectively referred 
to herein as the "Prospectus"; provided, however, that all references to the 
"Registration Statement" and the "Prospectus" shall also be deemed to include 
all documents incorporated therein by reference pursuant to the Securities 
Exchange Act of 1934, as amended (the "1934 Act"), prior to the execution of 
the applicable Terms Agreement; provided, further, that if the Company files 
a registration statement with the Commission pursuant to Rule 462(b) of the 
1933 Act Regulations (the "Rule 462 Registration Statement"), then, after 
such filing, all references to "Registration Statement" shall also be deemed 
to include the Rule 462 Registration Statement; and provided, further, that 
if the Company elects to rely upon Rule 434 of the 1933 Act Regulations, then 
all references to "Prospectus" shall also be deemed to include the final or 
preliminary prospectus, as the case may be, and the applicable term sheet or 
abbreviated term sheet (the "Term Sheet"), as the case may be, in the form 
first furnished to the Underwriters by the Company in reliance upon Rule 434 
of the 1933 Act Regulations, and all references in this Underwriting 
Agreement to the date of the Prospectus shall mean the date of the Term 
Sheet.  For purposes of this Underwriting Agreement, all references to the 
Registration Statement, Prospectus, Term Sheet or preliminary prospectus or 
to any amendment or supplement to any of the foregoing shall be deemed to 
include any copy filed with the Commission pursuant to its Electronic Data 
Gathering, Analysis and Retrieval system ("EDGAR").  

    All references in this Underwriting Agreement to financial statements and 
schedules and other information which is "contained," "included" or "stated" 
(or other references of like import) in the Registration Statement, 
Prospectus or preliminary prospectus shall be deemed to mean and include all 
such financial statements and schedules and other information which is 
incorporated by reference in the Registration Statement, Prospectus or 
preliminary prospectus, as the case may be; and all references in this 
Underwriting Agreement to amendments or supplements to the Registration 
Statement, Prospectus or preliminary prospectus shall be deemed to mean and 
include the filing of any document under the 1934 Act which is incorporated 
by reference in the Registration Statement, Prospectus or preliminary 
prospectus, as the case may be.

    SECTION 1.  Representations and Warranties.

    (a) The Company represents and warrants to you, as of the date hereof, 
and to each Underwriter named in the applicable Terms Agreement, as of the 
date thereof, as of the Closing Time (as defined below) and, if applicable, 
as of each Date of Delivery (as defined below) (in each case, a 
"Representation Date"), as follows:

                                     -3-

<PAGE>
       (1)  The Company meets the requirements for use of Form S-3 under the 
    1933  Act. Each of the Registration Statement and any Rule 462(b) 
    Registration Statement has become effective under the 1933 Act and no 
    stop order suspending the effectiveness of the Registration Statement or 
    any Rule 462(b) Registration Statement has been issued under the 1933 Act 
    and no proceedings for that purpose have been instituted or are pending 
    or, to the knowledge of the Company, are contemplated by the Commission, 
    and any request on the part of the Commission for additional information 
    has been complied with. In addition, each Indenture has been duly 
    qualified under the 1939 Act.

         At the respective times the Registration Statement, any Rule 462(b) 
    Registration Statement and any post-effective amendments thereto 
    (including the filing of the Company's most recent Annual Report on Form 
    10-K with the Commission (the "Annual Report on Form 10-K")) became 
    effective and at each Representation Date, the Registration Statement, 
    any Rule 462(b) Registration Statement and any amendments and supplements 
    thereto complied and will comply in all material respects with the 
    requirements of the 1933 Act and the 1933 Act Regulations and did not and 
    will not 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. At the date of the Prospectus, at the 
    Closing Time and at each Date of Delivery, if any, the Prospectus and any 
    amendments and supplements thereto did not and will not 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. If the Company 
    elects to rely upon Rule 434 of the 1933 Act Regulations, the Company 
    will comply with the requirements of Rule 434. Notwithstanding the 
    foregoing, the representations and warranties in this subsection shall 
    not apply to statements in or omissions from the Registration Statement 
    or the Prospectus made in reliance upon and in conformity with 
    information furnished to the Company in writing by any Underwriter 
    through you expressly for use in the Registration Statement or the 
    Prospectus.

              Each preliminary prospectus and prospectus filed as part of the 
    Registration Statement as originally filed or as part of any amendment 
    thereto, or filed pursuant to Rule 424 under the 1933 Act, complied when 
    so filed in all material respects with the 1933 Act Regulations and each 
    preliminary prospectus and the Prospectus delivered to the Underwriters 
    for use in connection with the offering of Underwritten Securities will, 
    at the time of such delivery, be identical to any electronically 
    transmitted copies thereof filed with the Commission pursuant to EDGAR, 
    except to the extent permitted by Regulation S-T.

            (2)  The documents incorporated or deemed to be incorporated by 
    reference in the Registration Statement and the Prospectus, at the time 
    they were or hereafter are filed with the Commission, complied and will 
    comply in all material respects with the requirements of the 1934 Act and 
    the rules and regulations of the Commission thereunder (the "1934 Act 
    Regulations") and, when read together with the other information in the 
    Prospectus, at the date of the Prospectus, at the Closing Time and at 
    each Date of Delivery, if any, did not

    and will not include an untrue statement of a material fact or omit to 
    state a material fact necessary to make the statements therein, in the 
    light of the circumstances under which they were made, not misleading.

       (3)  The accountants who certified the financial statements and any 
    supporting schedules thereto included in the Registration Statement and 
    the Prospectus are independent public accountants as required by the 1933 
    Act and the 1933 Act Regulations.

       (4)  The financial statements of the Company included in the 
    Registration Statement and the Prospectus, together with the related 
    schedules and notes, present fairly the financial position of the Company 
    and its consolidated subsidiaries, at the dates indicated and the 
    statement of operations, shareholders' equity and cash flows of the 
    Company and its consolidated subsidiaries for the periods specified. Such 
    financial statements have been prepared in conformity with generally 
    accepted accounting principles ("GAAP") applied on a consistent basis 
    throughout the periods involved. The supporting schedules, if any, 
    included in the Registration Statement and the Prospectus present fairly 
    in accordance with GAAP the information required to be stated therein. 
    The selected financial data and the summary financial information 
    included in the Prospectus present fairly the information shown therein 
    and have been compiled on a basis consistent with that of the audited 
    financial statements included in the Registration Statement and the 
    Prospectus. Any historical summaries of revenue and certain operating 
    expenses included or incorporated by reference in the Registration 
    Statement and the Prospectus present fairly the revenue and those 
    operating expenses included in such summaries of the properties related 
    thereto for the periods specified in conformity with GAAP. In addition, 
    any pro forma financial statements of the Company and its subsidiaries 
    and the related notes thereto included in the Registration Statement and 
    the Prospectus present fairly the information shown therein, have been 
    prepared in accordance with the Commission's rules and guidelines with 
    respect to pro forma financial statements and have been properly compiled 
    on the bases described therein, and the assumptions used in the 
    preparation thereof are reasonable and the adjustments used therein are 
    appropriate to give effect to the transactions and circumstances referred 
    to therein.

        (5)  Since the respective dates as of which information is given in 
    the Registration Statement and the Prospectus, except as otherwise stated 
    therein, (A) there has been no material adverse change in the condition, 
    financial or otherwise, or in the earnings, business affairs or business 
    prospects of the Company and its subsidiaries considered as one 
    enterprise, whether or not arising in the ordinary course of business (a 
    "Material Adverse Effect"), (B) there have been no transactions entered 
    into by the Company or any of its subsidiaries, other than those arising 
    in the ordinary course of business, which are material with respect to 
    the Company and its subsidiaries considered as one enterprise and (C) 
    except for regular dividends on the Company's shares of beneficial 
    interest, in amounts per share that are consistent with past practice, 
    there has been no dividend or distribution of any kind declared, paid or 
    made by the Company on any class of its capital stock.

    contemplated under, this Underwriting Agreement and the applicable Terms 
    Agreement.  The Company is duly qualified to transact business in each

    whether by reason of the ownership or leasing of property or the conduct 
    of business, except where the failure to so qualify or be in good 
    standing would not result in a Material Adverse Effect.  Except as 
    otherwise stated in the Registration Statement and the Prospectus, all of 
    the issued and outstanding capital stock or other ownership interests of 
    each Subsidiary have been duly authorized and validly issued, are fully 
    paid and non-assessable and are owned by the Company, directly or through

    reinvestment plans, reservations, agreements or employee benefit plans 
    referred to in the Prospectus or pursuant to the exercise of convertible 
    securities or options referred to in the Prospectus). Such shares of 
    beneficial interest have been duly authorized and validly issued by the 
    Company and are fully paid and non-assessable, and none of such shares of 
    beneficial interest was issued in violation of preemptive or other 
    similar rights of any security holder of the Company.

    Agreement as of the date thereof will have been, duly authorized,

    Underwritten Securities, when issued and delivered by the Company 
    pursuant to this Agreement and such Terms Agreement against payment of 
    the consideration therefor specified in such Terms Agreement will be 
    validly issued, fully paid and non-assessable and will not be subject to

    Terms Agreement against payment of the consideration therefor specified 
    in such Terms Agreement, will be validly issued, fully paid and 
    non-assessable and will not be subject to preemptive or other similar 
    rights arising by operation of law or otherwise; and the Designating 
    Amendment establishing the preferences, limitations and relative rights 
    of any Preferred Shares will be in full force and effect prior to the 
    Closing Time.

       (12) If the Underwritten Securities being sold pursuant to the 
    applicable Terms Agreement include Common Share Warrants, such 
    Underwritten Securities have been, or as of the date of such Terms 
    Agreement will have been, duly authorized by the Company for issuance and 
    sale pursuant to this Underwriting Agreement and such Terms Agreement.  
    Such Underwritten Securities, when issued and authenticated in the manner 
    provided for the applicable Warrant Agreement and delivered against 
    payment of the consideration therefor specified in such Terms Agreement, 
    will constitute valid and legally binding obligations of the Company, 
    entitled to the benefits provided by such Warrant Agreement and 
    enforceable against the Company in accordance with their terms, except as 
    enforcement thereof may be limited by bankruptcy, insolvency, 
    reorganization, moratorium or other similar laws relating to or affecting 
    creditors' rights generally or by general equitable principles.

       (13)  If the Underwritten Securities being sold pursuant to the 
    applicable Terms Agreement include Common Share Warrants, the applicable 
    Warrant Agreement has been, or prior to the issuance of such Underwritten 
    Securities will have been, duly authorized, executed and delivered by the 
    Company and, upon such authorization, execution and delivery, will 
    constitute a valid and legally binding agreement of the Company, 
    enforceable against the Company in accordance with its terms, except as 
    enforcement thereof may be limited by bankruptcy, insolvency, 
    reorganization, moratorium or other similar laws relating to or affecting 
    creditors' rights generally or by general equitable principles.

       (14) If applicable, the Underlying Securities have been, or as of the 
    date of the applicable Terms Agreement will have been, duly authorized 
    and reserved for issuance by the Company upon exercise of the Common 
    Share Warrants or upon conversion of the related Preferred 

                                     -7-

    Shares, as applicable.  The Underlying Securities, when issued upon such 
    exercise or conversion, as applicable, will be validly issued, fully paid 
    and non-assessable and will not be subject to preemptive or other similar 
    rights of any securityholder of the Company.

        (15)  The Underwritten Securities being sold pursuant to the 
    applicable Terms Agreement and the applicable Warrant Agreement as of the 
    date of the Prospectus, and any Underlying Securities, when issued and 
    delivered in accordance with the terms of the related Underwritten 
    Securities, will conform in all material respects to the statements 
    relating thereto contained in the Prospectus and will be in substantially 
    the form filed or incorporated by reference, as the case may be, as an 
    exhibit to the Registration Statement.

        (16)  Neither the Company nor any of its subsidiaries is in violation 
    of its declaration of trust, partnership agreement, charter, by-laws or 
    other organizational document or in default in the performance or 
    observance of any obligation, agreement, covenant or condition contained 
    in any contract, indenture, mortgage, deed of trust, loan or credit 
    agreement, note, lease or other agreement or instrument to which the 
    Company or any of its subsidiaries is a party or by which it or any of 
    them may be bound, or to which any of the property or assets of the 
    Company or any of its subsidiaries is subject, except for such defaults 
    that would not result in a Material Adverse Effect.  The execution, 
    delivery and performance of this Underwriting Agreement, the applicable 
    Terms Agreement, each applicable Warrant Agreement and any other 
    agreement or instrument entered into or issued or to be entered into or 
    issued by the Company in connection with the transactions contemplated 
    hereby or thereby or in the Registration Statement and the Prospectus and 
    the consummation of the transactions contemplated herein and in the 
    Registration Statement and the Prospectus and compliance by the Company 
    with its obligations hereunder and thereunder have been duly authorized 
    by all necessary action on the part of the Company  and do not and will 
    not, whether with or without the giving of notice or passage of time or 
    both, conflict with or constitute a breach of, or default under, or 
    result in the creation or imposition of any lien, charge or encumbrance 
    upon any assets, properties or operations of the Company or any of its 
    subsidiaries pursuant to, any contract, indenture, mortgage, deed of 
    trust, loan or credit agreement, note, lease or other agreement or 
    instrument to which the Company or any of its subsidiaries is a party or 
    which it or any of them may be bound or to which any property or assets 
    of the Company or any of its subsidiaries is subject (except for such 
    conflicts, breaches, defaults, events or liens, charges or encumbrances 
    that would not result in a Material Adverse Effect) nor will such action 
    result in any violation of the provisions of the declaration of trust, 
    partnership agreement, charter, by-laws, or other organizational 
    documents of the Company or any of its subsidiaries or any applicable 
    law, statute, rule, regulation, judgment, order, writ or decree of any 
    government, government instrumentality or court, domestic or foreign, 
    having jurisdiction over the Company or any if its subsidiaries or any of 
    their assets, properties or operations.

      (17)  There is not pending or threatened any action, suit, proceeding, 
    inquiry or investigation before or brought by any court or governmental 
    agency or body, domestic or

    against or affecting the Company or any of its subsidiaries which is 
    required to be disclosed in the Registration Statement and the Prospectus 
    (other than as stated therein), or which might reasonably be expected to 
    result in a Material Adverse Effect, or which might reasonably be 
    expected to materially and adversely affect the assets, properties or 
    operations thereof, the consummation of the transactions contemplated 
    under this Underwriting Agreement or the applicable Terms Agreement or 
    any applicable Warrant Agreement or the performance by the Company of its 
    obligations hereunder and thereunder.  The aggregate of all pending legal

    subsidiaries is a party or of which any of their respective assets, 
    properties or operations is the subject which are not described in the

    litigation incidental to the business, could not reasonably be expected 
    to result in a Material Adverse Effect.

       (18)  There are no contracts or documents which are required to be 
    described in the Registration Statement, the Prospectus or the documents 
    incorporated by reference therein or to be filed as exhibits thereto 
    which have not been so described and filed as required.

       (19)   Each approval, consent, order, authorization, designation, 
    declaration or filing by or with any regulatory, administrative or other 
    governmental body necessary in connection with the execution and delivery 
    by the Company of this Underwriting Agreement, the applicable Terms 
    Agreement and any applicable Warrant Agreement and the consummation of 
    the transactions herein and therein contemplated (except such additional 
    steps as may be necessary to qualify the Underwritten Securities for 
    public offering by the Underwriters under state securities or Blue Sky 
    laws) has been obtained or made and is in full force and effect.

       (20)  The Company and its subsidiaries hold all licenses, certificates 
    and permits from governmental authorities which are necessary to the 
    conduct of their business the absence of which would result in a Material 
    Adverse Effect; and neither the Company nor any subsidiary has infringed 
    any patents, patent rights, trade names, trademarks or copyrights, which 
    infringement would result in a Material Adverse Effect.

       (21)  With respect to all tax periods regarding which the Internal 
    Revenue Service is or will be entitled to assert any claim, the Company 
    has met the requirements for qualification as a real estate investment 
    trust under Sections 856 through 860 of the Internal Revenue Code, as

    and income continue to meet such requirements.

       (22)  The Company and its subsidiaries have good and marketable title 
    to, or valid and enforceable leasehold estates in, all items of real and 
    personal property referred to in the Prospectus as owned or leased by 
    them, in each case free and clear of all liens, encumbrances, claims, 
    security interests and defects, other than those referred to in the 
    Prospectus or which are not material in amount.  The Company has no 
    reason to believe that

                                     -9-

<PAGE>

    the lessee under any lease (excluding leases for which rent payments due 
    for the remainder of such lease are less than $500,000) calling for 
    annual lease payments in excess of $500,000 is not financially capable of 
    performing its obligations thereunder.

        (23)  The Company has filed all Federal, State and foreign income tax 
    returns which have been required to be filed and has paid all taxes 
    indicated by said returns and all assessments received by it to the 
    extent that such taxes have become due.

        (24)  The Company is not, and upon the issuance and sale of the 
    Underwritten Securities as herein contemplated and the application of the 
    net proceeds therefrom as described in the Prospectus will not be, an

    any hazardous substances, hazardous materials, toxic substances or waste 
    materials (collectively, "Hazardous Materials") on any of the properties 
    owned by it or any of its subsidiaries, or of (b) any unlawful spills, 
    releases, discharges or disposal of Hazardous Materials that have 
    occurred or are presently occurring off such properties as a result of 
    any construction on or operation and use of such properties which 
    presence or occurrence, singly or in the aggregate, would result in a 
    Material Adverse Effect.  In connection with the construction on or 
    peration and the use of the properties owned by the Company and its 
    subsidiaries, the Company represents that, as of the date of this 
    Underwriting Agreement and will represent that, as of the date of the 
    applicable Terms Agreement, it has no knowledge of any failure to comply 
    with all applicable local, state and federal environmental laws, 
    regulations, ordinances and administrative and judicial orders relating 
    to the generation, recycling, reuse, sale, storage, handling, transport 
    and disposal of any Hazardous Materials which failure would result in a 
    Material Adverse Effect.

      (26)  The Company has complied with, and is and will be in compliance 
    with, the provisions of that certain Florida act relating to disclosure 
    of doing business with Cuba, codified as Section 517.075 of the Florida 
    statutes, and the rules and regulations thereunder or is exempt therefrom.

(b) Any certificate signed by any officer of the Company or any of its 
subsidiaries and delivered to any Underwriter or to counsel for the 
Underwriters in connection with the offering of the Underwritten Securities 
shall be deemed a representation and warranty by the Company to each 
Underwriter as to the matters covered thereby on the date of such certificate 
and, unless subsequently amended or supplemented, at each Representation Date 
subsequent thereto.

    SECTION 2.  Sale and Delivery to Underwriters; Closing.

    (a) The several commitments of the Underwriters to purchase the 
Underwritten Securities pursuant to the applicable Terms Agreement shall be 
deemed to have been made on the basis of the 

                                     -10-

<PAGE>

representations and warranties herein contained and shall be subject to the 
terms and conditions herein set forth.

    (b) In addition, subject to the terms and conditions herein set forth, 
the Company may grant, if so provided in the applicable Terms Agreement, an 
option to the Underwriters, severally and not jointly, to purchase up to the 
number of Option Underwritten Securities set forth therein at a price per 
Option Underwritten Security equal to the price per Initial Underwritten 
Security, less an amount equal to any dividends or distributions declared by 
the Company and paid or payable on the Initial Underwritten Securities but 
not payable on the Option Underwritten Securities.  Such option, if granted, 
will expire 30 days after the date of such Terms Agreement, and may be 
exercised in whole or in part from time to time only for the purpose of 
covering over-allotments which may be made in connection with the offering 
and distribution of the Initial Underwritten Securities upon notice by you to 
the Company setting forth the number of Option Underwritten Securities as to 
which the several Underwriters are then exercising the option and the time, 
date and place of payment and delivery for such Option Underwritten 
Securities.  Any such time and date of payment and delivery (each, a "Date of 
Delivery") shall be determined by you, but shall not be later than seven full 
business days after the exercise of said option, nor in any event prior to 
the Closing Time, unless otherwise agreed upon by you and the Company.  If 
the option is exercised as to all or any portion of the Option Underwritten 
Securities, each of the Underwriters, acting severally and not jointly, will 
purchase that proportion of the total number of Option Underwritten 
Securities then being purchased which the number of Initial Underwritten 
Securities each such Underwriter has severally agreed to purchase as set 
forth in such Terms Agreement bears to the total number of Initial 
Underwritten Securities.

    (c) Payment of the purchase price for, and delivery of, the Initial 
Underwritten Securities shall be made at the offices of Andrews & Kurth 
L.L.P., 1701 Pennsylvania Avenue, N.W., Washington, D.C.  20006, or at such 
other place as shall be agreed upon by you and the Company, at 10:00 A.M. 
(Eastern time) on the third (fourth, if the pricing occurs after 4:30 P.M. 
(Eastern time) on any given day) business day after the date of the 
applicable Terms Agreement (unless postponed in accordance with the 
provisions of Section 10 hereof), or such other time not later than ten 
business days after such date as shall be agreed upon by you and the Company 
(such time and date of payment and delivery being herein called "Closing 
Time").  In addition, in the event that the Underwriters have exercised their 
option, if any, to purchase any or all of the Option Underwritten Securities, 
payment of the purchase price for, and delivery of such Option Underwritten 
Securities, shall be made at the above-mentioned offices of Andrews & Kurth 
L.L.P., or at such other place as shall be agreed upon by you and the 
Company, on the relevant Date of Delivery as specified in the notice from you 
to the Company.

    Payment shall be made to the Company by wire transfer of immediately 
available funds to a bank account designated by the Company, against delivery 
to you for the respective accounts of the Underwriters of the Underwritten 
Securities to be purchased by them.  It is understood that each Underwriter 
has authorized you, for its account, to accept delivery of, receipt for, and 
make payment of the purchase price for, the Underwritten Securities which it 
has severally agreed to purchase. 

                                     -11-

<PAGE>

You, individually and not as representative of the Underwriters, may (but 
shall not be obligated to) make payment of the purchase price for the 
Underwritten Securities to be purchased by any Underwriter whose funds have 
not been received by the Closing Time or the relevant Date of Delivery, as 
the case may be, but such payment shall not relieve such Underwriter from its 
obligations hereunder.

    (d) The Underwritten Securities shall be in such denominations and 
registered in such names as you may request in writing at least one full 
business day prior to the Closing Time or the relevant Date of Delivery, as 
the case may be. The Underwritten Securities will be made available for 
examination and packaging by you in The City of New York not later than 10:00 
A.M. (Eastern time) on the business day prior to the Closing Time or the 
relevant Date of Delivery, as the case may be.

    SECTION 3.  Covenants of the Company.  The Company covenants with you and 
with each Underwriter participating in the offering of Underwritten 
Securities, as follows:

        (a)  The Company will comply with the requirements of Rule 434 of the 
    1933 Act Regulations, if and as applicable, and will notify the 
    Representative(s) immediately, and confirm the notice in writing, of (i) 
    the effectiveness of any post-effective amendment to the Registration 
    Statement or the filing of any supplement or amendment to the Prospectus, 
    (ii) the receipt of any comments from the Commission, (iii) any request 
    by the Commission for any amendment to the Registration Statement or any 
    amendment or supplement to the Prospectus or for additional information, 
    and (iv) the issuance by the Commission of any stop order suspending the 
    effectiveness of the Registration Statement or of any order preventing or 
    suspending the use of any preliminary prospectus, or of the suspension of 
    the qualification of the Underwritten Securities for offering or sale in 
    any jurisdiction, or of the initiation or threatening of any proceedings 
    for any of such purposes.  The Company will promptly effect the filings 
    necessary pursuant to Rule 424 and will take such steps as it deems 
    necessary to ascertain promptly whether the Prospectus transmitted for 
    filing under Rule 424 was received for filing by the Commission and, in 
    the event that it was not, it will promptly file the Prospectus.  The 
    Company will make every reasonable effort to prevent the issuance of any 
    stop order and, if any stop order is issued, to obtain the lifting 
    thereof at the earliest possible moment.

        (b)  The Company will give you notice of its intention to file or 
    prepare any amendment to the Registration Statement (including any filing 
    under Rule 462(b) of the 1933 Act Regulations), any Term Sheet or any 
    amendment, supplement or revision to either the prospectus included in 
    the Registration Statement at the time it became effective or to the 
    Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, 
    will furnish you with copies of any such documents a reasonable amount of 
    time prior to such proposed filing or use, as the case may be, and will 
    not file or use any such document to which you or counsel for the 
    Underwriters shall object.

        (c)  The Company has furnished or will deliver to you and counsel for 
    the Underwriters, without charge, signed copies of the Registration 
    Statement as originally filed and of each amendment thereto (including 
    exhibits filed therewith or incorporated by reference therein and 
    documents incorporated or deemed to be incorporated by reference therein) 
    and signed copies of all consents and certificates of experts, and will 
    also deliver to you, without charge, a conformed copy of the Registration 
    Statement as originally filed and of each amendment thereto (without 
    exhibits) for each of the Underwriters. Copies of the Registration 
    Statement and each amendment thereto furnished to the Underwriters will 
    be identical to any electronically transmitted copies thereof filed with 
    the Commission pursuant to EDGAR, except to the extent permitted by 
    Regulation S-T.

        (d)  The Company will deliver to each Underwriter, without charge, as 
    many copies of each preliminary prospectus as such Underwriter may 
    reasonably request, and the Company hereby consents to the use of such 
    copies for purposes permitted by the 1933 Act.  The Company will furnish 
    to each Underwriter, without charge, during the period when the 
    Prospectus is required to be delivered under the 1933 Act or the 1934 
    Act, such number of copies of the Prospectus as such Underwriter may 
    reasonably request.  The Prospectus and any amendments or supplements 
    thereto furnished to the Underwriters will be identical to any 
    electronically transmitted copies thereof filed with the Commission 
    pursuant to EDGAR, except to the extent permitted by Regulation S-T.

        (e)  The Company will comply with the 1933 Act and the 1933 Act 
    Regulations and the 1934 Act and the 1934 Act Regulations so as to permit 
    the completion of the distribution of the Underwritten Securities as 
    contemplated in this Underwriting Agreement and the applicable Terms 
    Agreement and in the Registration Statement and the Prospectus.  If at 
    any time when the Prospectus is required by the 1933 Act or the 1934 Act 
    to be delivered in connection with sales of the Underwritten Securities, 
    any event shall occur or condition shall exist as a result of which it is 
    necessary, in the opinion of counsel for the Underwriters or for the 
    Company, to amend the Registration Statement in order that the 
    Registration Statement will not 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 or to amend or 
    supplement the Prospectus in order that the Prospectus will not include 
    an  untrue statement of a material fact or omit to state a material fact 
    necessary in order to make the statements therein not misleading in the 
    light of the circumstances existing at the time it is delivered to a 
    purchaser, or if it shall be necessary, in the opinion of such counsel, 
    at any such time to amend the Registration Statement or amend or 
    supplement the Prospectus in order to comply with the requirements of the 
    1933 Act or the 1933 Act Regulations, the Company will promptly prepare 
    and file with the Commission, subject to Section 3(b), such amendment or 
    supplement as may be necessary to correct such statement or omission or 
    to make the Registration Statement or the Prospectus comply with such 
    requirements, and the Company will furnish to the Underwriters, without 
    charge, such number of copies of such amendment or supplement as the 
    Underwriters may reasonably request.

       (f)  The Company will use its best efforts, in cooperation with the 
    Underwriters, to qualify the Underwritten Securities and any related 
    Underlying Securities for offering and sale under the applicable 
    securities laws of such states and other jurisdictions (domestic or 
    foreign) as you may designate and to maintain such qualifications in 
    effect for a period of not less than one year from the date of the 
    applicable Terms Agreement; provided, however, that the Company shall not 
    be obligated to file any general consent to service of process or to 
    qualify as a foreign corporation or as a dealer in securities in any 
    jurisdiction in which it is not so qualified or to subject itself to 
    taxation in respect of doing business in any jurisdiction in which it is 
    not otherwise so subject.  In each jurisdiction in which the Underwritten 
    Securities or any related Underlying Securities have been so qualified, 
    the Company will file such statements and reports as may be required by 
    the laws of such jurisdiction to continue such qualification in effect 
    for a period of not less than one year from the date of such Terms 
    Agreement.

       (g)  The Company will timely file such reports pursuant to the 1934 
    Act as are necessary in order to make generally available to its security 
    holders as soon as practicable an earnings statement for the purposes of, 
    and to provide the benefits contemplated by, the last paragraph of 
    Section 11(a) of the 1933 Act. 

       (h) If applicable, the Company will reserve and keep available at all 
    times, free of preemptive or other similar rights, a sufficient number of 
    Common Shares for the purpose of enabling the Company to satisfy any 
    obligations to issue such Underlying Securities upon exercise of the 
    related Common Share Warrants, as applicable, or upon conversion of the 
    Preferred Shares, as applicable.

       (i)  The Company will use the net proceeds received by it from the 
    sale of the Underwritten Securities in the manner specified in the 
    Prospectus under "Use of Proceeds".

       (j)  The Company will use its best efforts to effect the listing of 
    the Underwritten Securities and any related Underlying Securities, prior 
    to the Closing Time, on any national securities exchange or quotation 
    system if and as specified in the applicable Terms Agreement.

       (k)  Between the date of the applicable Terms Agreement and the 
    Closing Time or such other date specified in such Terms Agreement, the 
    Company will not, without your prior written consent, directly or 
    indirectly, issue, sell, offer to sell, grant any option for the sale of, 
    or otherwise dispose of, the securities specified in such Terms Agreement.

       (l) If the applicable Terms Agreement relates to Common Shares, the 
    Company will cause each of its officers and trustees to enter into a 
    written agreement, in form and substance satisfactory to you, to the 
    effect that, during a period of 90 days from the date of the applicable 
    Terms Agreement, they will not directly or indirectly sell, offer or 
    contract to sell, grant any option for the sale of, or otherwise dispose 
    of or transfer, any Common Shares (including, without limitation, any 
    options or warrants to acquire Common Shares), whether

                                     -14-

    then owned or thereafter acquired by them or with respect to which they 
    have or thereafter acquire the power of disposition, without your prior 
    written consent.

      (m) The Company, during the period when the Prospectus is required to 
    be delivered under the 1933 Act or the 1934 Act, will file all documents 
    required to be filed with the Commission pursuant to the 1934 Act within 
    the time periods required by the 1934 Act and the 1934 Act Regulations.

      (n) The Company will elect to qualify as a "real estate investment 
    trust" under the Internal Revenue Code of 1986, as amended, and will use 
    its best efforts to continue to meet the requirements to qualify as a 
    "real estate investment trust".

related Underlying Securities under state securities laws in accordance with 
the provisions of Section 3(f) hereof, including filing fees and the

organizations for the rating of the Underwritten Securities,  and if 
applicable, (viii) the fees and expenses incurred with respect to the listing 
of the Underwritten Securities and any related Underlying Securities.

    (b) If the applicable Terms Agreement is terminated by you in accordance 
with the provisions of Section 5 or Section 9(b)(i) hereof, the Company shall 
reimburse the Underwriters for all of their out-of-pocket expenses, including 
the reasonable fees and disbursements of counsel for the Underwriters.

    SECTION 5.  Conditions of Underwriters' Obligations.  The obligations of 
the Underwriters to purchase and pay for the Underwritten Securities pursuant 
to the applicable Terms Agreement are 

                                     -15-

subject to the accuracy of the representations and warranties of the Company 
contained in Section 1 hereof or in certificates of any officer of the 
Company or any of its subsidiaries delivered pursuant to the provisions

    Registration Statement, has become effective under the 1933 Act and no 
    stop order suspending the effectiveness of the Registration Statement 
    shall have been issued under the 1933 Act and no proceedings for that 
    purpose shall have been initiated or be pending or threatened by the 
    Commission, and any request on the part of the Commission for additional 
    information shall have been complied with to the reasonable satisfaction 
    of counsel to the Underwriters.  A prospectus containing information

    method of distribution and similar matters shall have been filed with the 
    Commission in accordance with Rule 424(b)(1), (2), (3), (4) or (5), as 
    applicable, or, if the Company has elected to rely upon Rule 434 of the 
    1933 Act Regulations, a Term Sheet including the Rule 434 Information 
    shall have been filed with the Commission in accordance with Rule 
    424(b)(7).

        (b)  At Closing Time, you shall have received:

              (1)  The favorable opinion, dated as of Closing Time, of Arent 
          Fox Kintner Plotkin & Kahn, counsel for the Company, in form and 
          substance satisfactory to counsel for the Underwriters, to the 
          effect that:

                   (i)  The Company has been duly organized and is validly 
               existing as a real estate investment trust in good standing 
               under the laws of the State of Maryland, with trust power and 
               authority to own, lease and operate its properties and conduct 
               its business as described in the Prospectus and to enter into 
               and perform its obligations under the Underwriting Agreement 
               and the applicable Terms Agreement; and the conditions for use 
               of a registration statement on Form S-3 have been satisfied.

                   (ii) The Company is duly qualified to transact business in 
               each jurisdiction in which such qualification is required, 
               whether by reason of the ownership or leasing of property or 
               the conduct of business except where the failure to so qualify 
               would not result in a Material Adverse Effect. 

                   (iii) Each Subsidiary has been duly organized and is 
               validly existing as a corporation or partnership, as the case 
               may be, in good standing under the laws of the jurisdiction of 
               its organization and has power and authority to own, lease and 
               operate its properties and to conduct its business as 
               described in the Prospectus.  Except as otherwise stated in 
               the Registration Statement and the Prospectus, all of the 
               issued and outstanding capital stock or other ownership 
               interests of each Subsidiary have been duly authorized and are 
               validly 

                                     -16-

<PAGE>

               issued, are fully paid and non-assessable and, to the best of 
               the knowledge of such counsel, are owned by the Company, 
               directly or through subsidiaries, free and clear of any 
               security interest, mortgage, pledge, lien, encumbrance, claim 
               or equity.

                  (iv)  Each Subsidiary of the Company is duly qualified as a 
               foreign corporation to transact business and is in good 
               standing in each jurisdiction which such qualification is 
               required, whether by reason of the ownership or leasing of 
               property or the conduct of business, except where the failure 
               to so qualify or be in good standing would not result in a 
               Material Adverse Effect.

                  (v)  The authorized, issued and outstanding shares of 
               beneficial interest of the Company are as set forth in the 
               Prospectus under the caption "Capitalization" (except for 
               subsequent issuances thereof, if any, contemplated under the 
               Underwriting Agreement, pursuant to dividend reinvestment 
               plans, reservations, agreements or employee benefit plans 
               referred to in the Prospectus or pursuant to the exercise of 
               convertible securities or options referred to in the 
               Prospectus).  Such shares of beneficial interest have been 
               duly authorized and validly issued by the Company and are 
               fully paid and non-assessable, and none of such shares of 
               beneficial interest was issued in violation of preemptive or 
               other similar rights arising by operation of law or, to the 
               best of their knowledge and information, otherwise.

                  (vi)  The Underwriting Agreement and the applicable Terms 
               Agreement have been duly authorized, executed and delivered by 
               the Company. 

                  (vii) If the Underwritten Securities being sold pursuant to 
               the applicable Terms Agreement include Common Shares, such 
               Underwritten Securities have been duly authorized by the 
               Company for issuance and sale pursuant to this Agreement and 
               such Terms Agreement; and such Underwritten Securities, when 
               issued and delivered by the Company pursuant to this Agreement 
               and such Terms Agreement against payment of the consideration 
               therefor specified in such Terms Agreement, will be validly 
               issued, fully paid and non-assessable and will not be subject 
               to preemptive or other similar rights arising by operation of 
               law or, to the best of their knowledge and information, 
               otherwise.

                 (viii) If the Underwritten Securities being sold pursuant to 
               the applicable Terms Agreement include Preferred Shares, such 
               Underwritten Securities have been duly authorized by the 
               Company for issuance and sale pursuant to this Agreement and 
               such Terms Agreement; the Underwritten Securities, when issued 
               and delivered by the Company pursuant to this Agreement and 

                                     -17-

<PAGE>

               such Terms Agreement against payment of the consideration 
               therefor specified in such Terms Agreement, will be validly 
               issued, fully paid and non-assessable and will not be subject 
               to preemptive or other similar rights arising by operation of 
               law or, to the best of their knowledge and information, 
               otherwise; and the Designating Amendment establishing the 
               preferences, limitations and relative rights of any Preferred 
               Shares is in full force and effect. 

                 (ix)  If the Underwritten Securities being sold pursuant to 
               the applicable Terms Agreement include Common Share Warrants, 
               such Underwritten Securities have been duly authorized by the 
               Company for issuance and sale pursuant to the Underwriting 
               Agreement and the applicable Terms Agreement.  The 
               Underwritten Securities, when issued and authenticated in the 
               manner provided for in the applicable Warrant Agreement and 
               delivered against payment of the consideration therefor 
               specified in such Terms Agreement, will constitute valid and 
               legally binding obligations of the Company, entitled to the 
               benefits provided by such Warrant Agreement and enforceable 
               against the Company in accordance with their terms, except as 
               enforcement thereof may be limited by bankruptcy, insolvency, 
               reorganization, moratorium or other similar laws relating to 
               or affecting creditors' rights generally or by general 
               equitable principles.

                  (x) If the Underwritten Securities being sold pursuant to 
               the applicable Terms Agreement include Common Share Warrants, 
               the applicable Warrant Agreement has been duly authorized, 
               executed and delivered by the Company and (assuming due 
               authorization, execution and delivery thereof by the Warrant 
               Agent) constitutes a valid and legally binding agreement of 
               the Company, enforceable against the Company in accordance 
               with its terms, except as enforcement thereof may be limited 
               by bankruptcy, insolvency, reorganization, moratorium or other 
               similar laws relating to or affecting creditors' rights 
               generally or by general equitable principles.

                   (xi)  If applicable, the Underlying Securities have been 
               duly authorized and reserved for issuance by the Company upon 
               exercise of the Common Share Warrants or upon conversion of 
               the related Preferred Shares, as applicable.  The Underlying 
               Securities, when issued upon such exercise or upon such 
               conversion, as applicable, will be validly issued, fully paid 
               and non-assessable and will not be subject to preemptive or 
               other similar rights  arising by operation of law or, to the 
               best of their knowledge and information, otherwise.

                   (xii)  The form of certificate used to evidence the 
               Underwritten Securities and any related Underlying Securities 
               is in due and proper form and complies with all applicable 
               statutory requirements.

                 (xiii) The Underwritten Securities being sold pursuant to 
               the applicable Terms Agreement and the applicable Warrant 
               Agreement conform, and any Underlying Securities, when issued 
               and delivered in accordance with the terms of the related 
               Underwritten Securities, will conform, in all material 
               respects to the statements relating thereto contained in the 
               Prospectus and are in substantially the form filed or 
               incorporated by reference, as the case may be, as an exhibit 
               to the Registration Statement.

                  (xiv)  The statements in the Prospectus under "Description 
               of Shares", "Description of Common Shares", if any, 
               "Description of Preferred Shares", if any, "Description of 
               Common Share Warrants", "Description of Underlying 
               Securities", if any, and "Certain Federal Income Tax 
               Considerations", if any,  and in the Registration Statement 
               under Item 15, insofar as such statements constitute a summary 
               of documents referred to therein or matters of law, are 
               accurate summaries and fairly and correctly present the 
               information called for with respect to such documents and 
               matters in all material respects.

                   (xv)  Such counsel does not know of any contracts or 
               documents required to be filed as exhibits to or incorporated 
               by reference in the Registration Statement or described in the 
               Registration Statement or the Prospectus which are not so 
               filed, incorporated by reference or described as required, and 
               such contracts and documents as are summarized in the 
               Registration Statement or the Prospectus are fairly summarized 
               in all material respects (except that such counsel need 
               express no opinion as to the financial statements, schedules 
               and other financial information included or incorporated by 
               reference therein).

                  (xvi)  The execution, delivery and performance of the 
               Underwriting Agreement, the applicable Terms Agreement and the 
               applicable Warrant Agreement and the consummation of the 
               transactions contemplated therein and compliance by the 
               Company with its obligations thereunder do not constitute a 
               breach of any of the terms or provisions of, or constitute a 
               default under, (a) the declaration of trust, partnership 
               agreement, charter, by-laws, or other organizational document 
               of the Company or any of its subsidiaries, (b) certain 
               specified agreements which are set forth on a schedule to such 
               opinion to which the Company is a party, (c) any order known 
               to such counsel of any court or government agency or body 
               having jurisdiction over the Company or any of its 
               subsidiaries or any of their properties.

                 (xvii)  To the best of such counsel's knowledge, neither the 
               Company nor any of its subsidiaries is in violation of its 
               declaration of trust, partnership agreement, charter, by-laws 
               or other organizational document.

                 (xviii)  Such counsel knows of no material legal proceedings 
               pending or threatened against the Company.

                  (xix)  No approval, consent, order, authorization, 
               designation, declaration or filing by or with any regulatory, 
               administrative or other governmental body is necessary in 
               connection with the execution and delivery of the Underwriting 
               Agreement, the applicable Terms Agreement or any applicable 
               Warrant Agreement and the consummation of the transactions 
               therein contemplated by the Company (other than as may be 
               required by the NASD or State securities or Blue Sky laws, as 
               to which such counsel need express no opinion) except such as 
               have been obtained or made, specifying the same.

                  (xx) The investments of the Company described in the 
               Prospectus are permitted investments under its declaration of 
               trust.

                  (xxi) The Company has qualified to be taxed as a real 
               estate investment trust pursuant to Sections 856-860 of the 
               Internal Revenue Code, as amended, for the fiscal years ended 
               December 31, 1992 through December 31, 1996, and the Company's 
               present method of operation and its assets and contemplated 
               income are such that the Company is in a position under 
               present law to so qualify for the fiscal year ending December 
               31, 1997, and under the present law the federal income tax 
               treatment of the Company and its shareholders will be as set 
               forth in the Prospectus under the heading "Description of 
               Shares".

                   (xxii)  The Registration Statement has been declared 
               effective under the 1933 Act.  Any required filing of the 
               Prospectus pursuant to Rule 424(b) has been made in the manner 
               and within the time period required by Rule 424(b).  To the 
               best of such counsel's knowledge, no stop order suspending the 
               effectiveness of the Registration Statement has been issued 
               under the 1933 Act and no proceedings for that purpose have 
               been initiated or are pending or threatened by the Commission.

                    (xxiii)  The Registration Statement and the Prospectus, 
               excluding the documents incorporated by reference therein, and 
               each amendment or supplement to the Registration Statement and 
               Prospectus, excluding the documents incorporated by reference 
               therein, as of their respective effective or issue dates 
               (other than the financial statements and supporting schedules 
               included therein or omitted therefrom, as to which such 
               counsel need express 

                                     -20-

<PAGE> 

               no opinion) complied as to form in all material respects with 
               the requirements of the 1933 Act and the 1933 Act Regulations.

                    (xxiv)  The documents incorporated by reference in the 
               Prospectus (other than the financial statements and supporting 
               schedules therein or omitted therefrom, as to which such 
               counsel need express no opinion), when they were filed with 
               the Commission, complied as to form in all material respects 
               with the requirements of the 1934 Act and the rules and 
               regulations of the Commission thereunder.

                   (xxv)  The Company is not an "investment company" within 
               the meaning of the 1940 Act.

              In rendering such opinion, Arent Fox Kintner Plotkin & Kahn may 
          rely as to matters governed by the laws of jurisdictions other than 
          Maryland and Delaware or Federal laws on local counsel in such 
          jurisdictions, provided that in each case Arent Fox Kintner Plotkin 
          & Kahn shall state that they believe that they and the Underwriters 
          are justified in relying on such other counsel.  In addition to the 
          matters set forth above, such opinion shall also include a 
          statement to the effect that nothing has come to the attention of 
          such counsel which leads them to believe that the Registration 
          Statement, as of the time it became effective under the 1933 Act or 
          at the date of the applicable Terms Agreement, contained an untrue 
          statement of a material fact or omitted to state a material fact 
          required to be stated therein or necessary to make the statements 
          therein not misleading or that the Prospectus, at the date of the 
          applicable Terms Agreement or at Closing Time, contained or 
          contains an untrue statement of a material fact or omitted or omits 
          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 (except that such counsel need express no view 
          as to financial statements, schedules and other financial 
          information included or incorporated by reference therein).  With 
          respect to such statement, Arent Fox Kintner Plotkin & Kahn may 
          state that their belief is based upon the procedures set forth 
          therein, but is without independent check and verification.

              (2)  The favorable opinion, dated as of Closing Time, of 
          Andrews & Kurth L.L.P., counsel for the Underwriters, with respect 
          to the matters set forth in (vi), (vii), (viii), (ix), (xi), (xii) 
          (only with respect to the statements set forth under "Description 
          of Shares", "Description of Common Shares", "Description of 
          Preferred Shares", "Description of Common Share Warrants" and 
          "Description of Underlying Securities", if any), (xxii) and (xxiii) 
          of subsection (b)(l) of this Section.  In addition to the matters 
          set forth above, such opinion shall also include a statement to the 
          effect that nothing has come to the attention of such counsel which 
          leads them to  believe that the Registration Statement, as of the 
          time it

                                     -21-

<PAGE>

          became effective under the 1933 Act or at the date of the applicable 
          Terms Agreement, contained an untrue statement of a material fact 
          or omitted to state a material fact required to be stated therein 
          or necessary to make the statements therein not misleading or that 
          the Prospectus, at the date of the applicable Terms Agreement or at 
          Closing Time, contained or contains an untrue statement of a 
          material fact or omitted or omits 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 
          (except that such counsel need express no view as to financial 
          statements, schedules and other financial information included or 
          incorporated by reference therein). With respect to such statement, 
          Andrews & Kurth L.L.P. may state that their belief is based upon 
          the procedures set forth therein, but is without independent check 
          and verification.

        (c)  At Closing Time, there shall not have been, since the date of 
the applicable Terms Agreement or since the respective dates as of which 
information is given in the Prospectus, any material adverse change in the 
condition, financial or otherwise, or in the earnings, business affairs or 
business prospects of the Company and its subsidiaries considered as one 
enterprise, whether or not arising in the ordinary course of business, and 
you shall have received a certificate of the President or a Vice President of 
the Company and of the chief financial officer or chief accounting officer of 
the Company, dated as of Closing Time, to the effect that (i) there has been 
no such material adverse change, (ii) the representations and warranties in 
Section 1 are true and correct with the same force and effect as though 
expressly made at and as of the Closing Time, (iii) the Company has complied 
with all agreements and satisfied all conditions on its part to be performed 
or satisfied at or prior to the Closing Time, and (iv) no stop order 
suspending the effectiveness of the Registration Statement has been issued 
and no proceedings for that purpose have been initiated or threatened by the 
Commission.

        (d)  At the time of the execution of the applicable Terms Agreement, 
you shall have received from Arthur Andersen LLP a letter dated such date, in 
form and substance satisfactory to you, to the effect that (i) they are 
independent public accountants with respect to the Company and its 
subsidiaries as required by the 1933 Act and the 1934 Act and the applicable 
published rules and regulations thereunder; (ii) it is their opinion that the 
consolidated financial statements and supporting schedules of the Company and 
its subsidiaries included or incorporated by reference in the Registration 
Statement and covered by their opinions therein comply as to form in all 
material respects with the applicable accounting requirements of the 1933 Act 
and the 1934 Act and the related published rules and regulations thereunder; 
(iii) based upon limited procedures set forth in detail in such letter (which 
shall include, without limitation, the procedures specified by the American 
Institute of Certified Public Accountants for a review of interim financial 
information as described in SAS No. 71, Interim Financial Information, with 
respect to the unaudited condensed consolidated financial statements of the 
Company and its

                                     -22-

<PAGE>

    subsidiaries included or incorporated by reference in the Registration 
Statement), nothing has come to their attention which causes them to believe 
that:

             (1)  any material modifications should be made to the unaudited 
    condensed consolidated financial statements included or incorporated by 
    reference in the Registration Statement for them to be in conformity with 
    generally accepted accounting principles;

             (2)  the unaudited condensed consolidated financial statements 
    included or incorporated by reference in the Registration Statement do 
    not comply as  to form in all material respects with the applicable 
    accounting requirements of the 1933 Act and the 1934 Act as it applies to 
    Form 10-Q and the related published rules and regulations;

             (3)  at a specified date not more than three days prior to the 
    date of such letter, there was any change in the capitalization of the 
    Company and its subsidiaries, any decrease in total assets, any change in 
    long-term debt or any change in short-term borrowings of the Company and 
    its subsidiaries, as compared with the amounts shown in the most recent 
    consolidated balance sheet incorporated by reference in the Registration 
    Statement; or

             (4)  during the period from the date of the most recent 
    consolidated balance sheet incorporated by reference in the Registration 
    Statement to a specified date not more than three days prior to the date 
    of such letter, there were any decreases, as compared with the 
    corresponding period in the preceding year, in real estate rental 
    revenue, net income or net income per share of the Company and its 
    subsidiaries;

except in all cases for changes, increases or decreases which the 
Registration Statement discloses have occurred or may occur; (iv) in addition 
to the limited procedures referred to in clause (iii) above, they have 
carried out certain specified procedures, not constituting an audit, with 
respect to certain amounts, percentages and financial information which are 
derived from the general accounting records of the Company and its 
subsidiaries, which are included or incorporated by reference in the 
Registration Statement and which are specified by you, and have compared such 
amounts, percentages and financial information with the accounting records of 
the Company and its subsidiaries and have found them to be in agreement; and 
(v) they have compared the information in the Prospectus under the caption 
"Selected Financial Data" with the disclosure requirements of Regulation S-K 
and on the basis of limited procedures specified in such letter nothing came 
to their attention as a result of the foregoing procedures that caused them 
to believe that this information does not conform in all material respects 
with the disclosure requirements of Item 301 of Regulation S-K.

            (e)  At Closing Time, you shall have received from Arthur 
    Andersen LLP a letter, dated as of Closing Time, to the effect that they 
    reaffirm the statements made in the letter furnished pursuant to 
    subsection (d) of this Section 5, except that the specified date referred 
    to shall be a date not more than three business days prior to the Closing 
    Time.

             (f)  At the time of the execution of the applicable Terms 
    Agreement, you  shall have received from Price Waterhouse L.L.P. a letter 
    dated such date, in  form and substance satisfactory to you, to the 
    effect that (i) they are  independent public accountants with respect to 
    the Company and its subsidiaries  as required by the 1933 Act and the 
    1934 Act and the applicable published rules  and regulations thereunder; 
    and (ii) it is their opinion that the consolidated financial statements 
    and supporting schedules of the Company and its subsidiaries included or 
    incorporated by reference in the Registration Statement and covered by 
    their opinions therein comply as to form in all material respects with 
    the applicable accounting requirements of the 1933 Act and the 1934 Act 
    and the related published rules and regulations thereunder.

             (g)  If applicable, at the time of the execution of the 
    applicable Terms Agreement, you  shall have received a letter dated such 
    date from such independent accountants that have prepared any historical 
    financial statements included in or incorporated by referenced into the 
    Registration Statement and Prospectus which financial statements relate 
    to properties or assets acquired or to be acquired by the Company, or any 
    of its subsidiaries, in form and substance satisfactory to the 
    Underwriters, to the effect that (i) they are independent accountants 
    with respect to the Company and such properties or assets acquired by the 
    Company within the meaning of the 1933 Act and the 1933 Act Regulations; 
    and (ii) it is their opinion that the historical financial statements for 
    such properties or assets that have been audited by them and covered by 
    their opinions included or incorporated by reference into the 
    Registration Statement and the Prospectus comply in form in all material 
    respects with the applicable accounting requirements of the 1933 Act and 
    the 1933 Act Regulations.

        (h)  At Closing Time and at any relevant Date of Delivery, the 
    Underwritten Securities shall have the ratings accorded by any 
    "nationally recognized statistical rating organization", as defined by 
    the Commission for purposes of Rule 436(g)(2) of the 1933 Act 
    Regulations, if and as specified in the applicable Terms Agreement, and 
    the Company shall have delivered to you a letter, dated as of such date, 
    from each such rating organization, or other evidence satisfactory to 
    you, confirming that the Underwritten Securities have such ratings.  
    Since the time of execution of such Terms Agreement, there shall not have 
    occurred a downgrading in the rating assigned to the Underwritten 
    Securities or any of the Company's other securities by any such rating 
    organization, and no such rating organization shall have publicly 
    announced that it has under surveillance or review its rating of the 
    Underwritten Securities or any of the Company's other securities.

                                     -24-

        (i)  At Closing Time, the Underwritten Securities shall have been 
    approved for listing, subject only to official notice of issuance, if and 
    as specified in the applicable Terms Agreement.

        (j) On the date of the applicable Terms Agreement, you shall have 
    received, in form and substance satisfactory to you, each lock-up 
    agreement, if any, specified in such Terms Agreement as being required to 
    be delivered by the persons listed therein.

        (k)  In the event that the Underwriters are granted an over-allotment 
    option by the Company in the applicable Terms Agreement and the 
    Underwriters exercise their option to purchase all or any portion of the 
    Option Underwritten Securities, the representations and warranties of the 
    Company contained herein and the statements in any certificates furnished 
    by the Company or any of its subsidiaries hereunder shall be true and 
    correct as of each Date of Delivery, and, at the relevant Date of 
    Delivery, you shall have received:

             (1)  A certificate, dated such Date of Delivery, of the 
          President or a Vice President of the Company and the chief

          on the letter furnished pursuant to this paragraph shall be a date 
          not more than three business days prior to such Date of Delivery.

        (l)  At Closing Time and at each Date of Delivery, counsel for the 
    Underwriters shall have been furnished with such documents and opinions 
    as they may require for the purpose of enabling them to pass upon the

<PAGE>

    as herein contemplated shall be satisfactory in form and substance to you 
    and counsel for the Underwriters.

        (m)  If any condition specified in this Section 5 shall not have been

    Agreement (or, with respect to the Underwriters' exercise of any 
    applicable over-allotment option for the purchase of Option Underwritten 
    Securities on a Date of Delivery after the Closing Time, the obligations 
    of the Underwriters to purchase the Option Underwritten Securities on 
    such Date of Delivery) may be terminated by you by notice to the Company 
    at any time at or prior to the Closing Time (or such Date of Delivery, as 
    applicable), and such termination shall be without liability of any party 
    to any other party except as provided in Section 4 and except that 
    Sections 1, 6, 7 and 8 shall survive any such termination and remain in 
    full force and effect.

    SECTION 6.  Indemnification.

    (a) The Company hereby agrees to indemnify and hold harmless each 
Underwriter and each person, if any, who controls any Underwriter within the 
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as 
follows:

        (1)  against any and all loss, liability, claim, damage and expense 
    whatsoever, as incurred, arising out of any untrue statement or alleged 
    untrue statement of a material fact contained in the Registration 
    Statement (or any amendment thereto), including the Rule 434 Information 
    deemed to be a part thereof, if applicable, or the omission or alleged 
    omission therefrom of a material fact required to be stated therein or 
    necessary to make the statements therein not misleading or arising out of 
    any untrue statement or alleged untrue statement of a material fact 
    included in any preliminary prospectus or the Prospectus (or any 
    amendment or supplement thereto), or the omission or alleged omission 
    therefrom of a material fact necessary in order to make the statements 
    therein, in the light of the circumstances under which they were made, 
    not misleading;

        (2)  against any and all loss, liability, claim, damage and expense 
    whatsoever, as incurred, to the extent of the aggregate amount paid in 
    settlement of any litigation, or any investigation or proceeding by any 
    governmental agency or body, commenced or threatened, or of any claim 
    whatsoever based upon any such untrue statement or omission, or any such 
    alleged untrue statement or omission; provided that any such settlement 
    is effected with the written consent of the Company; and

        (3)  against any and all expense whatsoever, as incurred (including, 
    subject to Section 6(c) hereof, the fees and disbursements of counsel 
    chosen by you), reasonably incurred in investigating, preparing or 
    defending against any litigation, or any investigation or proceeding by 
    any governmental agency or body, commenced or threatened, or any claim 
    whatsoever based upon any such untrue statement or omission, or any such 
    alleged untrue statement or omission, to the extent that any such expense 
    is not paid under (i) or (ii) above;

                                     -26-

<PAGE>

provided, however, that this indemnity agreement shall not apply to any loss, 
liability, claim, damage or expense to the extent arising out of any untrue 
statement or omission or alleged untrue statement or omission made in 
reliance upon and in conformity with written information furnished to the 
Company by any Underwriter through you expressly for use in the Registration 
Statement (or any amendment thereto), including the Rule 434 Information 
deemed to be a part thereof, if applicable, or any preliminary prospectus or 
the Prospectus (or any amendment or supplement thereto).

    (b) Each Underwriter severally agrees to indemnify and hold harmless the 
Company, its trustees, each of its officers who signed the Registration 
Statement, and each person, if any, who controls the Company within the 
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against 
any and all loss, liability, claim, damage and expense described in the 
indemnity contained in subsection (a) of this Section, as incurred, but only 
with respect to untrue statements or omissions, or alleged untrue statements 
or omissions, made in the Registration Statement (or any amendment thereto), 
including the Rule 434 Information deemed to be a part thereof, if 
applicable, or any preliminary prospectus or the Prospectus (or any amendment 
or supplement thereto) in reliance upon and in conformity with written 
information furnished to the Company by such Underwriter through you 
expressly for use in the Registration Statement (or any amendment thereto) or 
such preliminary prospectus or the Prospectus (or any amendment or supplement 
thereto).

    (c) Each indemnified party shall give notice as promptly as reasonably 
practicable to each indemnifying party of any action commenced against it in 
respect of which indemnity may be sought hereunder, but failure to so notify 
an indemnifying party shall not relieve such indemnifying party from any 
liability hereunder to the extent it is not materially prejudiced as a result 
thereof and in any event shall not relieve it from any liability which it may 
have otherwise than on account of this indemnity agreement.  In the case of 
parties indemnified pursuant to Section 6(a) above, counsel to the 
indemnified parties shall be selected by you, and, in the case of parties 
indemnified pursuant to Section 6(b) above, counsel to the indemnified 
parties shall be selected by the Company.  An indemnifying party may 
participate at its own expense in the defense of any such action; provided, 
however, that counsel to the indemnifying party shall not (except with the 
consent of the indemnified party) also be counsel to the indemnified party.  
In no event shall the indemnifying parties be liable for fees and expenses of 
more than one counsel (in addition to any local counsel) separate from their 
own counsel for all indemnified parties in connection with any one action or 
separate but similar or related actions in the same jurisdiction arising out 
of the same general allegations or circumstances.  No indemnifying party 
shall, without the prior written consent of the indemnified parties, settle 
or compromise or consent to the entry of any judgment with respect to any 
litigation, or any investigation or proceeding by any governmental agency or 
body, commenced or threatened, or any claim whatsoever in respect of which 
indemnification or contribution could be sought under this Section 6 or 
Section 7 hereof (whether or not the indemnified parties are actual or 
potential parties thereto), unless such settlement, compromise or consent (i) 
includes an unconditional release of each indemnified party from all 
liability arising out of such litigation, investigation, proceeding or claim 
and (ii) does not include a statement as to or an admission of fault, 
culpability or a failure to act by or on behalf of any indemnified party. 

                                 -27-

         SECTION 7.  Contribution.  If the indemnification provided for in 
Section 6 hereof is for any reason unavailable to or insufficient to hold 
harmless an indemnified party in respect of any losses, liabilities, claims, 
damages or expenses referred to therein, then each indemnifying party shall 
contribute to the aggregate amount of such losses, liabilities, claims, 
damages and expenses incurred by such indemnified party, as incurred, (i) in 
such proportion as is appropriate to reflect the relative benefits received 
by the Company, on the one hand, and the Underwriters, on the other hand, 
from the offering of the Underwritten Securities pursuant to the applicable 
Terms Agreement or (ii) if the allocation provided by clause (i) is not 
permitted by applicable law, in such proportion as is appropriate to reflect 
not only the relative benefits referred to in clause (i) above but also the 
relative fault of the Company, on the one hand, and of the Underwriters, on 
the other hand, in connection with the statements or omissions which resulted 
in such losses, liabilities, claims, damages or expenses, as well as any 
other relevant equitable considerations.

    The relative benefits received by the Company, on the one hand, and the 
Underwriters, on the other hand, in connection with the offering of the 
Underwritten Securities pursuant to the applicable Terms Agreement shall be 
deemed to be in the same respective proportions as the total net proceeds 
from the offering of such Underwritten Securities (before deducting expenses) 
received by the Company and the total underwriting discount received by the 
Underwriters, in each case as set forth on the cover of the Prospectus, or, 
if Rule 434 is used, the corresponding location on the Term Sheet, bear to 
the aggregate initial public offering price of such Underwritten Securities 
as set forth on such cover.

    The relative fault of the Company, on the one hand, and the Underwriters, 
on the other hand, shall be determined by reference to, among other things, 
whether any such untrue or alleged untrue statement of a material fact or 
omission or alleged omission to state a material fact relates to information 
supplied by the Company or by the Underwriters and the parties' relative 
intent, knowledge, access to information and opportunity to correct or 
prevent such statement or omission.

    The Company and the Underwriters agree that it would not be just and 
equitable if contribution pursuant to this Section 7 were determined by pro 
rata allocation (even if the Underwriters 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 above in this Section 7.  The 
aggregate amount of losses, liabilities, claims, damages and expenses 
incurred by an indemnified party and referred to above in this Section 7 
shall be deemed to include any legal or other expenses reasonably incurred by 
such indemnified party in investigating, preparing or defending against any 
litigation, or any investigation or proceeding by any governmental agency or 
body, commenced or threatened, or any claim whatsoever based upon any such 
untrue or alleged untrue statement or omission or alleged omission.

    Notwithstanding the provisions of this Section 7, no Underwriter shall be 
required to contribute any amount in excess of the amount by which the total 
price at which the Underwritten Securities underwritten by it and distributed 
to the public were offered to the public exceeds the

                                     -28-

<PAGE>

amount of any damages which such Underwriter has otherwise been required to 
pay by reason of any such untrue or alleged untrue statement or omission or 
alleged omission.

    No person guilty of fraudulent misrepresentation (within the meaning of 
Section 11(f) of the 1933 Act) shall be entitled to contribution from any 
person who was not guilty of such fraudulent misrepresentation.

    For purposes of this Section 7, each person, if any, who controls an 
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of 
the 1934 Act shall have the same rights to contribution as such Underwriter, 
and each trustee of the Company, each officer of the Company who signed the 
Registration Statement, and each person, if any, who controls the Company 
within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 
Act shall have the same rights to contribution as the Company.  The 
Underwriters' respective obligations to contribute pursuant to this Section 7 
are several in proportion to the number of Initial Underwritten Securities 
set forth opposite their respective names in the applicable Terms Agreement, 
and not joint.

    SECTION 8.  Representations, Warranties and Agreements to Survive 
Delivery.  All representations, warranties and agreements contained in this 
Underwriting Agreement or the applicable Terms Agreement or in certificates 
of officers of the Company submitted pursuant hereto or thereto shall remain 
operative and in full force and effect, regardless of any investigation made 
by or on behalf of any Underwriter or controlling person, or by or on behalf 
of the Company, and shall survive delivery of and payment for the 
Underwritten Securities.

    SECTION 9.  Termination.  

    (a) This Underwriting Agreement (excluding the applicable Terms 
Agreement) may be terminated for any reason at any time by the Company or by 
you upon the giving of 30 days' prior written notice of such termination to 
the other party hereto.

    (b) You may terminate the applicable Terms Agreement, by notice to the 
Company, at any time at or prior to the Closing Time or any relevant Date of 
Delivery, if (i) there has been, since the time of execution of such Terms 
Agreement or since the respective dates as of which information is given in 
the Prospectus, any material adverse change in the condition, financial or 
otherwise, or in the earnings, business affairs or business prospects of the 
Company and its subsidiaries considered as one enterprise, whether or not 
arising in the ordinary course of business, or (ii) if there has occurred any 
material adverse change in the financial markets in the United States or any 
outbreak of hostilities or escalation thereof or other calamity or crisis or 
any change or development involving a prospective change in national or 
international political, financial or economic conditions, in each case the 
effect of which is such as to make it, in your judgment, impracticable to 
market the Underwritten Securities or to enforce contracts for the sale of 
the Underwritten Securities, or (iii) trading in any securities of the 
Company has been suspended or limited by the Commission or the American Stock 
Exchange, or if trading generally on the New York Stock Exchange or the 
American Stock Exchange or in the Nasdaq National Market has been suspended 
or limited, or minimum or

                                     -29-

<PAGE>

maximum prices for trading have been fixed, or maximum ranges for prices have 
been required, by either of said exchanges or by such system or by order of 
the Commission, the NASD or any other governmental authority, or (iv) a 
banking moratorium has been declared by either Federal or New York 
authorities.

    (c) If this Underwriting Agreement or the applicable Terms Agreement is 
terminated pursuant to this Section 9, such termination shall be without 
liability of any party to any other party except as provided in Section 4 
hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such 
termination and remain in full force and effect.

    SECTION 10.  Default by One or More of the Underwriters.  If one or more 
of the Underwriters shall fail at the Closing Time or the relevant Date of 
Delivery, as the case may be, to purchase the Underwritten Securities which 
it or they are obligated to purchase under the applicable Terms Agreement 
(the "Defaulted Securities"), then you shall have the right, within 24 hours 
thereafter, to make arrangements for one or more of the non-defaulting 
Underwriters, or any other underwriters, to purchase all, but not less than 
all, of the Defaulted Securities in such amounts as may be agreed upon and 
upon the terms herein set forth; if, however, you shall not have completed 
such arrangements within such 24-hour period, then:

          (a)   if the number of Defaulted Securities does not exceed 10% of 
    the number of Underwritten Securities to be purchased on such date 
    pursuant to such Terms Agreement, the non-defaulting Underwriters shall 
    be obligated, severally and not jointly, to purchase the full number 
    thereof in the proportions that their respective underwriting obligations 
    under such Terms Agreement bear to the underwriting obligations of all 
    non-defaulting Underwriters, or

        (b)  if the number of Defaulted Securities exceeds 10% of the number 
    of Underwritten Securities to be purchased on such date pursuant to such 
    Terms Agreement, such Terms Agreement (or, with respect to the 
    Underwriters' exercise of any applicable over-allotment option for the 
    purchase of Option Underwritten Securities on a Date of Delivery after 
    the Closing Time, the obligations of the Underwriters to purchase, and 
    the Company to sell, such Option Underwritten Securities on such Date of 
    Delivery) shall terminate without liability on the part of any 
    non-defaulting Underwriter.

    No action taken pursuant to this Section 10 shall relieve any defaulting 
Underwriter from liability in respect of its default.

    In the event of any such default which does not result in (i) a 
termination of the applicable Terms Agreement or (ii) in the case of a Date 
of Delivery after the Closing Time, a termination of the obligations of the 
Underwriters and the Company with respect to the related Option Underwritten 
Securities, as the case may be, either you or the Company shall have the 
right to postpone the Closing Time or the relevant Date of Delivery, as the 
case may be, for a period not exceeding seven days

equivalent, determined pursuant to Section 301 as of the date such Security

of an Original Issue Discount Security, the Dollar equivalent as of such date 
of original issuance of the amount determined as provided in clause (i) 
above) of such Security, (iii) the principal amount of any Indexed Security 
that may be counted in making such determination or calculation and that 
shall be deemed outstanding for such purpose shall be equal to the principal 
face amount of such Indexed Security at original issuance, unless otherwise

         Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Indenture (including certificates
delivered pursuant to Section 1009) shall include:

         (1)  a statement that each individual signing such certificate or
    opinion has read such condition or covenant and the definitions herein
    relating thereto;

         (2)  a brief statement as to the nature and scope of the examination
    or investigation upon which the statements or opinions contained in such
    certificate or opinion are based;

         SECTION 103.  Form of Documents Delivered to Trustee.  In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified

representations with respect to the matters upon which his certificate or

representations may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Trust stating that the information as to such factual matters is in the
possession of the Trust, unless such counsel knows that the certificate or
opinion or representations as to such matters are erroneous.

                                  -11-

<PAGE>

         Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

         SECTION 104.  Acts of Holders.  (a)  Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders of the Outstanding Securities of
all series or one or more series, as the case may be, may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Holders in person or by agents duly appointed in writing.  If Securities of
a series are issuable as Bearer Securities, any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fifteen, or a combination of
such instruments and any such record.  Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Trust.  Such instrument or instruments and any such record (and
the action embodied therein and evidenced thereby) are herein sometimes referred
to as the "Act" of the Holders signing such instrument or instruments or so
voting at any such meeting.  Proof of execution of any such instrument or of a
writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture.  The record of
any meeting of Holders of Securities shall be proved in the manner provided in
Section 1506.

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

         (c)  The ownership of Registered Securities shall be proved by the
Security Register.

         (d)  The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depositary, by any trust company, bank, banker or other depositary, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depositary, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory.  The Trustee and the Trust may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit bearing
a 

                                  -12-

<PAGE>

later date issued in respect of the same Bearer Security is produced, or (2) 
such Bearer Security is produced to the Trustee by some other Person, or (3) 
such Bearer Security is surrendered in exchange for a Registered Security, or 
(4) such Bearer Security is no longer Outstanding.  The ownership of Bearer 
Securities may also be proved in any other manner which the Trustee deems 
sufficient.

         (e)  If the Trust shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Trust may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Trust shall have no obligation to do so. 
Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities shall be computed as of such record date;
provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than eleven months after the
record date.

    In the absence of any such record date fixed by the Trust, regardless as to
whether a solicitation of the Holders is occurring on behalf of the Trust or any
Holder, the Trustee may, at its option, fix in advance a record date for the
determination of such Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Trustee
shall have no obligation to do so.  Any such record date shall be a date not
more than 30 days prior to the first solicitation of Holders generally in
connection therewith no later than the date of such solicitation.

         (f)  Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future Holder
of the same Security and the Holder of every 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 Trustee, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Trust in
reliance thereon, whether or not notation of such action is made upon such
Security.

         SECTION 105.  Notices, etc., to Trustee and Trust.  Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,

                                  -13-

<PAGE>

         (1)  the Trustee by any Holder or by the Trust shall be sufficient for
    every purpose hereunder if made, given, furnished or filed in writing to or
    with the Trustee at __________________; Attention: _______________________.

         (2)  the Trust by the Trustee or by any Holder shall be sufficient for
    every purpose hereunder (unless otherwise herein expressly provided) if in
    writing and mailed, first class postage prepaid, to the Trust addressed to
    it at the address of its principal office specified in the first paragraph
    of this Indenture or at any other address previously furnished in writing
    to the Trustee by the Trust.

         SECTION 106.  Notice to Holders; Waiver.  Where this Indenture
provides for notice of any event to Holders of Registered Securities by the
Trust or the Trustee, such notice shall be sufficiently given (unless otherwise
herein expressly provided) if in writing and mailed, first-class postage
prepaid, to each such Holder affected by such event, at his address as it
appears in the Security Register, 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 of Registered Securities 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 of Registered Securities or the sufficiency of any
notice to Holders of Bearer Securities given as provided herein.  Any notice
mailed to a Holder in the manner herein prescribed shall be conclusively deemed
to have been received by such Holder, whether or not such Holder actually
receives such notice.

         If by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause it shall be impracticable to give such
notice by mail, then such notification to Holders of Registered Securities as
shall be made with the approval of the Trustee shall constitute a sufficient
notification to such Holders for every purpose hereunder.

         Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given if published in an Authorized Newspaper in New York
City and in such other city or cities as may be specified in such Securities on
a Business Day, such publication to be not later than the latest date, and not
earlier than the earliest date, prescribed for the giving of such notice.  Any
such notice shall be deemed to have been given on the date of such publication
or, if published more than once, on the date of the first such publication.

         If by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder.  Neither the failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so published, 


                                  -14-

<PAGE>

shall affect the sufficiency of such notice with respect to other Holders of 
Bearer Securities or the sufficiency of any notice to Holders of Registered 
Securities given as provided herein.

         Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

         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 precedent to the validity of any action taken in
reliance upon such waiver.

         SECTION 107.  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 108.  Successors and Assigns.  All covenants and agreements in
this Indenture by the Trust shall bind its successors and assigns, whether so
expressed or not.

         SECTION 109.  Separability Clause.  In case any provision in this
Indenture or in any Security or coupon 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 110.  Benefits of Indenture.  Nothing in this Indenture or in
the Securities or coupons, express or implied, shall give to any Person, other
than the parties hereto, any Security Registrar, any Paying Agent, any
Authenticating Agent and their successors hereunder and the Holders any benefit
or any legal or equitable right, remedy or claim under this Indenture.

         SECTION 111.  Governing Law.  This Indenture and the Securities and
coupons shall be governed by and construed in accordance with the law of the
State of New York.  This Indenture is subject to the provisions of the TIA that
are required to be part of this Indenture and shall, to the extent applicable,
be governed by such provisions.

         SECTION 112.  Legal Holidays.  In any case where any Interest Payment
Date, Redemption Date, Repayment Date, sinking fund payment date, Stated
Maturity or Maturity of any Security shall not be a Business Day at any Place of
Payment, then (notwithstanding any other provision of this Indenture or any
Security or coupon other than a provision in the Securities of any series which
specifically states that such provision shall apply in lieu hereof), payment of
interest or any Additional Amounts or principal (and premium, if any) need not
be made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date, Redemption Date, Repayment Date or
sinking fund payment date, or at the Stated Maturity or Maturity, provided that


                                  -15-

<PAGE>


no interest shall accrue on the amount so payable for the period from and after
such Interest Payment Date, Redemption Date, Repayment Date, sinking fund
payment date, Stated Maturity or Maturity, as the case may be.

         SECTION 113.  Immunity of Shareholders, Trustees, Officers and Agents
of the Trust.  The obligations of the Trust under the Indenture and the
Securities and all documents delivered in the name of the Trust in connection
herewith and therewith do not and shall not constitute personal obligations of
the trustees, officers, employees, agents or shareholders of the Trust or any of
them, and shall not involve any claim against or personal liability on the part
of any of them, and all persons including the Trustee shall look solely to the
assets of the Trust for the payment of any claim thereunder or for the
performance thereof and shall not seek recourse against such trustees, officers,
employees, agents or shareholders of the Trust or any of them or any of their
personal assets for such satisfaction.  The performance of the obligations of
the Trust under the Indenture and the Securities and all documents delivered in
the name of the Trust in connection therewith shall not be deemed a waiver of
any rights or powers of the Trust, trustees or shareholders under the Trust's
Declaration of Trust.

Indenture, or as may be required to comply with any law or with any rule or

exchange on which the Securities may be listed, or to conform to usage.

         Unless otherwise specified as contemplated by Section 301, Bearer

         The definitive Securities and coupons shall be printed, lithographed
or engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or may be produced in any other manner, all as

         SECTION 202.  Form of Trustee's Certificate of Authentication. 
Subject to Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

    This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

                        _____________________________________
                                      as Trustee


                        By __________________________________
                                  Authorized Signatory


         SECTION 203.  Securities Issuable in Global Form.  If Securities of or
within a series are issuable in global form, as specified as contemplated by
Section 301, then, notwithstanding clause (8) of Section 301 and the provisions
of Section 302, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
shall represent the aggregate amount of Outstanding Securities of such series
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities of such series represented thereby may from time to time be increased
or decreased to reflect exchanges.  Any endorsement of a Security in global form
to reflect the amount, or any increase or decrease in the amount, of Outstanding
Securities represented thereby shall be made by the Trustee in such manner and
upon instructions given by such Person or Persons as shall be specified therein
or in the Trust Order to be delivered to the Trustee pursuant to Section 303 or
304.  Subject to the provisions of Section 303 and, if applicable, Section 304,
the Trustee shall deliver and redeliver any Security in permanent global form in
the manner and upon instructions given by the Person or Persons specified
therein or in the applicable Trust Order.  If a Trust Order pursuant to Section
303 or 304 has been, or simultaneously is, delivered, any instructions by the
Trust with respect to endorsement or delivery or redelivery of a Security in
global form shall be in writing but need not comply with Section 102 and need
not be accompanied by an Opinion of Counsel.

         The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Trust and the Trust delivers to the Trustee the Security
in global form together with written instructions (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) with regard to
the reduction in the principal amount of Securities represented thereby,
together with the written statement contemplated by the last sentence of Section
303.

         Notwithstanding the provisions of Section 307, unless otherwise
specified as contemplated by Section 301, payment of principal of and any
premium and interest on any Security in permanent global form shall be made to
the Person or Persons specified therein.

         Notwithstanding the provisions of Section 308 and except as provided
in the preceding paragraph, the Trust, the Trustee and any agent of the Trust
and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a permanent
global Security in bearer form, Euroclear or CEDEL.

    thereof, the denominations in which any Registered Securities of the series

         (12) whether the amount of payments of principal of (and premium, if 
    any) or interest, if any, on the Securities of the series may be 
    determined with reference to an index, formula or other method (which 
    index, formula or method may be based, without limitation, on one or more

          (15) any deletions from, modifications of or additions to the Events 
    of Default or covenants of the Trust with respect to Securities of the 
    series, whether or not such Events of Default or covenants are consistent 
    with the Events of Default or covenants set forth herein;

          (16) whether Securities of the series are to be issuable as 
    Registered Securities, Bearer Securities (with or without coupons) or 
    both, any restrictions applicable to the offer, sale or delivery of Bearer 
    Securities and the terms upon which Bearer Securities of the series may be 
    exchanged for Registered Securities of the series and vice versa (if 
    permitted by applicable laws and regulations), whether any Securities of 
    the series are to be issuable initially in temporary global form and 
    whether any Securities of the series are to be issuable in permanent 
    global form with or without coupons and, if so, whether beneficial owners 
    of interests in any such permanent global Security may exchange such 
    interests for Securities of such series and of like tenor of any 
    authorized form and denomination and the circumstances under which any 
    such exchanges may occur, if other than in the manner provided in Section 
    305, and, if Registered Securities of the series are to be issuable as a

    any temporary global Security representing Outstanding Securities of the 
    series shall be dated if other than the date of original issuance of the 
    first Security of the series to be issued;

          (18) the Person to whom any interest on any Registered Security of 
    the series shall be payable, if other than the Person in whose name that 
    Security (or one or more Predecessor Securities) is registered at the 
    close of business on the Regular Record Date for such interest, the manner

<PAGE>

          (19) the applicability, if any, of Sections 1402 and/or 1403 to the 
    Securities of the series and any provisions in modification of, in 
    addition to or in lieu of any of the provisions of Article Fourteen;

          (20) if the Securities of such series are to be issuable in 
    definitive form (whether upon original issue or upon exchange of a 
    temporary Security of such series) only upon receipt of certain 
    certificates or other documents or satisfaction of other conditions, then 
    the form and/or terms of such certificates, documents or conditions;

          (21) whether and under what circumstances the Trust will pay 
    Additional Amounts as contemplated by Section 1010 on the Securities of 
    the series to any Holder who is not a United States person (including any 
    modification to the definition of such term) in respect of any tax, 
    assessment or governmental charge and, if so, whether the Trust will have 
    the option to redeem such Securities rather than pay such Additional 
    Amounts (and the terms of any such option);

          (22) the obligation, if any, of the Trust to permit the conversion 
    of the Securities of such series into the Trust's Common Shares or 
    Preferred Shares, as the case may be, and the terms and conditions upon 
    which such conversion shall be effected (including, without limitation, 
    the initial conversion price or rate, the conversion period, any 
    adjustment of the applicable conversion price and any requirements 
    relative to the reservation of such shares for purposes of conversion); 

          (23) if the Securities of or within the series are convertible into 
    the Trust's Common Shares or Preferred Shares, in connection with the 
    preservation of the status of the Trust as a "real estate investment 
    trust" qualified under Sections 856-859 of the Internal Revenue Code of 
    1986, as amended, any applicable limitations on the ownership or 
    transferability of the Common Shares or Preferred Shares into which such 
    Securities are convertible; and

          (24) any other terms of the series (which terms shall not be 
    inconsistent with the provisions of this Indenture).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officer's Certificate or in any such indenture supplemental
hereto.  All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

         If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) shall be certified by the Secretary or an Assistant
Secretary of the Trust and delivered to the Trustee at or 


                                  -21-

<PAGE>

prior to the delivery of the Officer's Certificate setting forth the terms of 
the Securities of such series.

         SECTION 302.  Denominations.  The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301.  With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions with respect to the Securities of any series, the
Registered Securities of such series, other than Registered Securities issued in
global form (which may be of any denomination), shall be issuable in
denominations of $1,000 and any integral multiple thereof and the Bearer
Securities of such series, other than Bearer Securities issued in global form
(which may be of any denomination), shall be issuable in a denomination of
$5,000.

         SECTION 303.  Execution, Authentication, Delivery and Dating.  The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Trust by an executive officer of the Trust and attested by its Secretary or
one of its Assistant Secretaries.  The signature of any of these individuals on
the Securities and coupons may be manual or facsimile signatures of the present
or any future such authorized officer and may be imprinted or otherwise
reproduced on the Securities.

         Securities or coupons bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Trust shall bind the
Trust, notwithstanding that such individuals or any of them have ceased to hold
such offices prior to the authentication and delivery of such Securities or did
not hold such offices at the date of such Securities or coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Trust may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Trust to the Trustee for
authentication, together with a Trust Order for the authentication and delivery
of such Securities, and the Trustee in accordance with the Trust Order shall
authenticate and deliver such Securities; provided, however, that, in connection
with its original issuance, no Bearer Security shall be mailed or otherwise
delivered to any location in the United States; and provided further that,
unless otherwise specified with respect to any series of Securities pursuant to
Section 301, a Bearer Security may be delivered in connection with its original
issuance only if the Person entitled to receive such Bearer Security shall have
furnished a certificate to Euroclear or Cedel, as the case may be, in the form
set forth in Exhibit A-1 to this Indenture or such other certificate as may be
specified with respect to any series of Securities pursuant to Section 301,
dated no earlier than 15 days prior to the earlier of the date on which such
Bearer Security is delivered and the date on which any temporary Security first
becomes exchangeable for such Bearer Security in accordance with the terms of
such temporary Security and this Indenture.  If any Security shall be
represented by a permanent global Bearer Security, then, for purposes of this
Section and Section 304, the notation of a beneficial owner's interest therein
upon original issuance of such Security or upon exchange of a portion of a
temporary global Security shall be deemed to be delivery in connection with its
original issuance of such beneficial owner's interest in such permanent global
Security.  Except as permitted by Section 306, the Trustee shall not
authenticate and deliver any 



                                  -22-

<PAGE>

Bearer Security unless all appurtenant coupons for interest then matured have 
been detached and canceled.

         If all the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Trust Order may set forth procedures acceptable to the
Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue.  In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to TIA Section 315(a) through 315(d)) shall be
fully protected in relying upon,

         (i)  an Opinion of Counsel stating that 

              (a)  the form or forms of such Securities and any coupons have
         been established in conformity with the provisions of this Indenture;

              (b)  the terms of such Securities and any coupons have been
         established in conformity with the provisions of this Indenture; and

              (c)  such Securities, together with any coupons appertaining
         thereto, when completed by appropriate insertions and executed and
         delivered by the Trust to the Trustee for authentication in accordance
         with this Indenture, authenticated and delivered by the Trustee in
         accordance with this Indenture and issued by the Trust in the manner
         and subject to any conditions specified in such Opinion of Counsel,
         will constitute legal, valid and binding obligations of the Trust,
         enforceable in accordance with their terms, subject to applicable
         bankruptcy, insolvency, reorganization and other similar laws of
         general applicability relating to or affecting the enforcement of
         creditors' rights generally and to general equitable principles; and

        (ii)  an Officer's Certificate stating that all conditions precedent
    provided for in this Indenture relating to the issuance of the Securities
    have been complied with and that, to the best of the knowledge of the
    signers of such certificate, no Event of Default with respect to any of the
    Securities shall have occurred and be continuing.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties,
obligations or immunities under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

         Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officer's Certificate otherwise required
pursuant to Section 301 or a Trust Order, or an Opinion of 

                                  -23-

<PAGE>

Counsel or an Officer's Certificate otherwise required pursuant to the 
preceding paragraph at the time of issuance of each Security of such series, 
but such order, opinion and certificates, with appropriate modifications to 
cover such future issuances, shall be delivered at or before the time of 
issuance of the first Security of such series.

         Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

         No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture.  Notwithstanding the foregoing, if any Security
shall have been authenticated and delivered hereunder but never issued and sold
by the Trust, and the Trust shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the Trust,
for all purposes of this Indenture such Security shall be deemed never to have
been authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

         SECTION 304.  Temporary Securities.  (a)  Pending the preparation of
definitive Securities of any series, the Trust may execute, and upon Trust Order
the Trustee shall authenticate and deliver, temporary Securities which are
printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Securities
in lieu of which they are issued, in registered form, or, if authorized, in
bearer form with one or more coupons or without coupons, and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Securities may determine, as conclusively evidenced by
their execution of such Securities.  In the case of Securities of any series,
such temporary Securities may be in global form.

         Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with Section 304(b) or as otherwise provided in or
pursuant to a Board Resolution), if temporary Securities of any series are
issued, the Trust will cause definitive Securities of that series to be prepared
without unreasonable delay.  After the preparation of definitive Securities of
such series, the temporary Securities of such series shall be exchangeable for
definitive Securities of such series upon surrender of the temporary Securities
of such series at the office or agency of the Trust in a Place of Payment for
that series, without charge to the Holder.  Upon surrender for cancellation of
any one or more temporary Securities of any series (accompanied by any
non-matured coupons appertaining thereto), the Trust shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series of authorized denominations;
provided, however, that no definitive Bearer Security shall be 


                                  -24-

<PAGE>

delivered in exchange for a temporary Registered Security; and provided 
further that a definitive Bearer Security shall be delivered in exchange for 
a temporary Bearer Security only in compliance with the conditions set forth 
in Section 303.  Until so exchanged, the temporary Securities of any series 
shall in all respects be entitled to the same benefits under this Indenture 
as definitive Securities of such series.

         (b)  Unless otherwise provided in or pursuant to a Board Resolution,
this Section 304(b) shall govern the exchange of temporary Securities issued in
global form other than through the facilities of The Depository Trust Company. 
If any such temporary Security is issued in global form, then such temporary
global Security shall, unless otherwise provided therein, be delivered to the
London office of a depositary or common depositary (the "Common Depositary"),
for the benefit of Euroclear and CEDEL, for credit to the respective accounts of
the beneficial owners of such Securities (or to such other accounts as they may
direct).

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Trust shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Trust.  On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depositary to the Trustee, as the Trust's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary global Security to be
exchanged.  The definitive Securities to be delivered in exchange for any such
temporary global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by the beneficial owner thereof; provided,
however, that, unless otherwise specified in such temporary global Security,
upon such presentation by the Common Depositary, such temporary global Security
is accompanied by a certificate dated the Exchange Date or a subsequent date and
signed by Euroclear as to the portion of such temporary global Security held for
its account then to be exchanged and a certificate dated the Exchange Date or a
subsequent date and signed by CEDEL as to the portion of such temporary global
Security held for its account then to be exchanged, each in the form set forth
in Exhibit A-2 to this Indenture or in such other form as may be established
pursuant to Section 301; and provided further that definitive Bearer Securities
shall be delivered in exchange for a portion of a temporary global Security only
in compliance with the requirements of Section 303.

         Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or CEDEL, as the case may be, to request such exchange on his behalf
and delivers to Euroclear or CEDEL, as the case may be, a certificate in the
form set forth in 


                                  -25-

<PAGE>

Exhibit A-1 to this Indenture (or in such other form as may be established 
pursuant to Section 301), dated no earlier than 15 days prior to the Exchange 
Date, copies of which certificate shall be available from the offices of 
Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed for such 
series of Securities and each Paying Agent.  Unless otherwise specified in 
such temporary global Security, any such exchange shall be made free of 
charge to the beneficial owners of such temporary global Security, except 
that a Person receiving definitive Securities must bear the cost of 
insurance, postage, transportation and the like unless such Person takes 
delivery of such definitive Securities in person at the offices of Euroclear 
or CEDEL.  Definitive Securities in bearer form to be delivered in exchange 
for any portion of a temporary global Security shall be delivered only 
outside the United States.

         Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and CEDEL on
such Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee
of a certificate or certificates in the form set forth in Exhibit A-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit A-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301).  Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
the temporary global Security with respect to which such certification was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners.  Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial interest in a temporary global Security will be
made unless and until such interest in such temporary global Security shall have
been exchanged for an interest in a definitive Security.  Any interest so
received by Euroclear and CEDEL and not paid as herein provided shall be
returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Trust.

         SECTION 305.  Registration, Registration of Transfer and Exchange. 
The Trust shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Trust in a Place of Payment a register for each
series of Securities (the registers maintained in such office or in any such
office or agency of the Trust in a Place of Payment being herein sometimes
referred to collectively as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Trust shall provide for the
registration of Registered Securities and of transfers of 


                                  -26-

<PAGE>

Registered Securities. The Security Register shall be in written form or any 
other form capable of being converted into written form within a reasonable 
time.  The Trustee, at its Corporate Trust Office, is hereby appointed 
"Security Registrar" for the purpose of registering Registered Securities and 
transfers of Registered Securities on such Security Register as herein 
provided.  In the event that the Trustee shall cease to be Security 
Registrar, it shall have the right to examine the Security Register at all 
reasonable times.

         Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Trust in a Place of Payment for that series, the Trust shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Registered Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

         Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency.  Whenever any such Registered Securities
are so surrendered for exchange, the Trust shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.  Unless otherwise specified with respect to any
series of Securities as contemplated by Section 301, Bearer Securities may not
be issued in exchange for Registered Securities.

         If (but only if) permitted by the applicable Board Resolution and
(subject to Section 303) set forth in the applicable Officers' Certificate, or
in any indenture supplemental hereto, delivered as contemplated by Section 301,
at the option of the Holder, Bearer Securities of any series may be exchanged
for Registered Securities of the same series of any authorized denominations and
of a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining.  If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Trust in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Trust and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States. 
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor 


                                  -27-

<PAGE>

after the close of business at such office or agency on (i) any Regular 
Record Date and before the opening of business at such office or agency on 
the relevant Interest Payment Date, or (ii) any Special Record Date and 
before the opening of business at such office or agency on the related 
proposed date for payment of Defaulted Interest, such Bearer Security shall 
be surrendered without the coupon relating to such Interest Payment Date or 
proposed date for payment, as the case may be, and interest or Defaulted 
Interest, as the case may be, will not be payable on such Interest Payment 
Date or proposed date for payment, as the case may be, in respect of the 
Registered Security issued in exchange for such Bearer Security, but will be 
payable only to the Holder of such coupon when due in accordance with the 
provisions of this Indenture.  Whenever any Securities are so surrendered for 
exchange, the Trust shall execute, and the Trustee shall authenticate and 
deliver, the Securities which the Holder making the exchange is entitled to 
receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph.  If the depositary for any permanent global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
global Security expressly permit such global Security to be exchanged in whole
or in part for definitive Securities, a global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such global Security selected or approved by the
Trust or to a nominee of such successor to DTC.  If at any time DTC notifies the
Trust that it is unwilling or unable to continue as depositary for the
applicable global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Securities Exchange Act of 1934 if so
required by applicable law or regulation, the Trust shall appoint a successor
depositary with respect to such global Security or Securities.  If (x) a
successor depositary for such global Security or Securities is not appointed by
the Trust within 90 days after the Trust receives such notice or becomes aware
of such unwillingness, inability or ineligibility, (y) an Event of Default has
occurred and is continuing and the beneficial owners representing a majority in
principal amount of the applicable series of Securities represented by such
global Security or Securities advise DTC to cease acting as depositary for such
global Security or Securities or (z) the Trust, in its sole discretion,
determines at any time that all Outstanding Securities (but not less than all)
of any series issued or issuable in the form of one or more global Securities
shall no longer be represented by such global Security or Securities, then the
Trust shall execute, and the Trustee shall authenticate and deliver definitive
Securities of like series, rank, tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of such global Security
or Securities.  If any beneficial owner of an interest in a permanent global
Security is otherwise entitled to exchange such interest for Securities of such
series and of like tenor and principal amount of another authorized form and
denomination, as specified as contemplated by Section 301 and provided that any
applicable notice provided in the permanent global Security shall have been
given, then without unnecessary delay but in any event not later than the
earliest date on which such interest may be so exchanged, the Trust shall
execute, and the Trustee shall authenticate and deliver definitive Securities in
aggregate principal amount equal to the principal amount of such beneficial
owner's interest in such permanent global Security.  On or after the earliest
date on which such interests may be so exchanged, such permanent global Security
shall be surrendered for exchange by DTC or such other depositary as shall be
specified in the Trust Order with respect 



                                  -28-

<PAGE>

thereto to the Trustee, as the Trust's agent for such purpose; provided, 
however, that no such exchanges may occur during a period beginning at the 
opening of business 15 days before any selection of Securities to be redeemed 
and ending on the relevant Redemption Date if the Security for which exchange 
is requested may be among those selected for redemption; and provided further 
that no Bearer Security delivered in exchange for a portion of a permanent 
global Security shall be mailed or otherwise delivered to any location in the 
United States.  If a Registered Security is issued in exchange for any 
portion of a permanent global Security after the close of business at the 
office or agency where such exchange occurs on (i) any Regular Record Date 
and before the opening of business at such office or agency on the relevant 
Interest Payment Date, or (ii) any Special Record Date and the opening of 
business at such office or agency on the related proposed date for payment of 
Defaulted Interest, interest or Defaulted Interest, as the case may be, will 
not be payable on such Interest Payment Date or proposed date for payment, as 
the case may be, in respect of such Registered Security, but will be payable 
on such Interest Payment Date or proposed date for payment, as the case may 
be, only to the Person to whom interest in respect of such portion of such 
permanent global Security is payable in accordance with the provisions of 
this Indenture.

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

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Trust or the
Security Registrar) be duly endorsed, or be accompanied by a written instrument
of transfer in form satisfactory to the Trust and the Security 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 Securities, but the Trust may require payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

         The Trust or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such Securities are issuable
only as Registered Securities, the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the first publication of the relevant notice of redemption or, if such
Securities are also issuable as Registered Securities and there is no
publication, the mailing of the relevant notice of redemption, or (ii) to
register the transfer of or exchange any Registered Security so selected for
redemption in whole or in part, except, in the case of any Registered Security
to be redeemed in part, the portion thereof not to be redeemed, or (iii) to
exchange any Bearer Security so selected for redemption except that such a
Bearer Security may be exchanged for a Registered Security of that series and
like tenor, provided that such 


                                  -29-

<PAGE>

Registered Security shall be simultaneously surrendered for redemption, or 
(iv) to issue, register the transfer of or exchange any Security which has 
been surrendered for repayment at the option of the Holder, except the 
portion, if any, of such Security not to be so repaid.

         SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.  If
any mutilated Security or a Security with a mutilated coupon appertaining to it
is surrendered to the Trustee or the Trust, together with, in proper cases, such
security or indemnity as may be required by the Trust or the Trustee to save
each of them or any agent of either of them harmless, the Trust shall execute
and the Trustee shall authenticate and deliver in exchange therefor a new
Security of the same series and principal amount, containing identical terms and
provisions and bearing a number not contemporaneously outstanding, with coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

         If there shall be delivered to the Trust and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Trust or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Trust shall execute and upon its request
the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost
or stolen Security or in exchange for the Security to which a destroyed, lost or
stolen coupon appertains (with all appurtenant coupons not destroyed, lost or
stolen), a new Security of the same series and principal amount, containing
identical terms and provisions and bearing a number not contemporaneously
outstanding, with coupons corresponding to the coupons, if any, appertaining to
such destroyed, lost or stolen Security or to the Security to which such
destroyed, lost or stolen coupon appertains.

         Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Trust in its discretion may, instead of
issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium, if any),
any interest on and any Additional Amounts with respect to, Bearer Securities
shall, except as otherwise provided in Section 1002, be payable only at an
office or agency located outside the United States and, unless otherwise
specified as contemplated by Section 301, any interest on Bearer Securities
shall be payable only upon presentation and surrender of the coupons
appertaining thereto.

         Upon the issuance of any new Security under this Section, the Trust
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 Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a 


                                  -30-

<PAGE>

destroyed, lost or stolen coupon appertains, shall constitute an original 
additional contractual obligation of the Trust, whether or not the destroyed, 
lost or stolen Security and its coupons, if any, or the destroyed, lost or 
stolen coupon 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 Securities of that series and their coupons, if any, 
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 Securities or coupons.

         SECTION 307.  Payment of Interest; Interest Rights Preserved.  Except
as otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that 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 Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular
Record Date for such interest at the office or agency of the Trust maintained
for such purpose pursuant to Section 1002; provided, however, that each
installment of interest on any Registered Security may at the Trust's option be
paid by (i) mailing a check for such interest, payable to or upon the written
order of the Person entitled thereto pursuant to Section 308, to the address of
such Person as it appears on the Security Register or (ii) transfer to an
account maintained by the payee located inside the United States.

         Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest may be made, in the case of
a Bearer Security, by transfer to an account maintained by the payee with a bank
located outside the United States.

         Unless otherwise provided as contemplated by Section 301, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such permanent global Security held for
its account by Cede & Co. or the Common Depositary, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

         In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.


                                  -31-

<PAGE>


         Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Trust, at its election in each case, as
provided in clause (1) or (2) below:

         (1)  The Trust may elect to make payment of any Defaulted Interest to
    the Persons in whose names the Registered Securities of such series (or
    their respective Predecessor Securities) 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 Trust shall
    notify the Trustee in writing of the amount of Defaulted Interest proposed
    to be paid on each Registered Security of such series and the date of the
    proposed payment (which shall not be less than 20 days after such notice is
    received by the Trustee), and at the same time the Trust shall deposit with
    the Trustee an amount of money in the currency or currencies, currency unit
    or units or composite currency or currencies in which the Securities of
    such series are payable (except as otherwise specified pursuant to Section
    301 for the Securities of such series) 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 on or 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
    Trust of such Special Record Date and, in the name and at the expense of
    the Trust, 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 Registered Securities of such series at
    his address as it appears in the Security Register not less than 10 days
    prior to such Special Record Date.  The Trustee may, in its discretion, in
    the name and at the expense of the Trust, cause a similar notice to be
    published at least once in an Authorized Newspaper in each place of
    payment, but such publications shall not be a condition precedent to the
    establishment of 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 Registered Securities of such series (or their
    respective Predecessor Securities) are registered at the close of business
    on such Special Record Date and shall no longer be payable pursuant to the
    following clause (2).  In case a Bearer Security of any series is
    surrendered at the office or agency in a Place of Payment for such series
    in exchange for a Registered Security of such series after the close of
    business at such office or agency on any Special Record Date and before the
    opening of business at such office or agency on the related proposed date
    for payment of Defaulted Interest, such Bearer Security shall be
    surrendered without the coupon relating to such proposed date of payment
    and Defaulted Interest will not be payable on such proposed date of payment
    in respect of the Registered Security issued in exchange for such 


                                  -32-

<PAGE>

    Bearer Security, but will be payable only to the Holder of such coupon 
    when due in accordance with the provisions of this Indenture.

         (2)  The Trust may make payment of any Defaulted Interest on the
    Registered Securities of any series in any other lawful manner not
    inconsistent with the requirements of any securities exchange on which such
    Securities may be listed, and upon such notice as may be required by such
    exchange, if, after notice given by the Trust to the Trustee of the
    proposed payment pursuant to this clause, such manner of payment shall be
    deemed practicable by the Trustee.

         Subject to the foregoing provisions of this Section and Section 305,
each Security delivered under this Indenture upon registration of transfer of or
in exchange for or in lieu of any other Security shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other
Security.

         SECTION 308.  Persons Deemed Owners.  Prior to due presentment of a
Registered Security for registration of transfer, the Trust, the Trustee and any
agent of the Trust or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium, if any), and (subject to
Sections 305 and 307) interest on, such Registered Security and for all other
purposes whatsoever, whether or not such Registered Security be overdue, and
neither the Trust, the Trustee nor any agent of the Trust or the Trustee shall
be affected by notice to the contrary.

         Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery.  The Trust, the Trustee and any agent of the Trust or
the Trustee may treat the Holder of any Bearer Security and the Holder of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and neither the
Trust, the Trustee nor any agent of the Trust or the Trustee shall be affected
by notice to the contrary.

         None of the Trust, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

         Notwithstanding the foregoing, with respect to any global Security,
nothing herein shall prevent the Trust, the Trustee, or any agent of the Trust
or the Trustee, from giving effect to any written certification, proxy or other
authorization furnished by any depositary, as a Holder, with respect to such
global Security or impair, as between such depositary and owners of beneficial
interests in such global Security, the operation of customary practices
governing the exercise of the rights of such depositary (or its nominee) as
Holder of such global Security.



                                  -33-

         SECTION 309.  Cancellation.  All Securities and coupons surrendered 
for payment, redemption, repayment at the option of the Holder, registration 
of transfer or exchange or for credit against any sinking fund payment shall, 
if surrendered to any Person other than the Trustee, be delivered to the 
Trustee, and any such Securities and coupons and Securities and coupons 
surrendered directly to the Trustee for any such purpose shall be promptly 
canceled by it; provided, however, where the Place of Payment is located 
outside of the United States, the Paying Agent at such Place of Payment may 
cancel the Securities surrendered to it for such purposes prior to delivering 
the Securities to the Trustee.  The Trust may at any time deliver to the 
Trustee for cancellation any Securities previously authenticated and 
delivered hereunder which the Trust may have acquired in any manner 
whatsoever, and may deliver to the Trustee (or to any other Person for 
delivery to the Trustee) for cancellation any Securities previously 
authenticated hereunder which the Trust has not issued and sold, and all 
Securities so delivered shall be promptly canceled by the Trustee.  If the 
Trust shall so acquire any of the Securities, however, such acquisition shall 
not operate as a redemption or satisfaction of the indebtedness represented 
by such Securities unless and until the same are surrendered to the Trustee 
for cancellation.  No Securities shall be authenticated in lieu of or in 
exchange for any Securities canceled as provided in this Section, except as 
expressly permitted by this Indenture.  Canceled Securities and coupons held 
by the Trustee shall be destroyed by the Trustee and the Trustee shall 
deliver a certificate of such destruction to the Trust, unless by a Trust 
Order the Trust directs their return to it.

         SECTION 310.  Computation of Interest.  Except as otherwise 
specified as contemplated by Section 301 with respect to Securities of any 
series, interest on the Securities of each series shall be computed on the 
basis of a 360-day year consisting of twelve 30-day months.

                                     ARTICLE FOUR

                              SATISFACTION AND DISCHARGE

         SECTION 401.  Satisfaction and Discharge of Indenture.  This 
Indenture shall upon Trust Request cease to be of further effect with respect 
to any series of Securities specified in such Trust Request (except as to any 
surviving rights of registration of transfer or exchange of Securities of 
such series herein expressly provided for and any right to receive Additional 
Amounts, as provided in Section 1010), and the Trustee, upon receipt of a 
Trust Order, and at the expense of the Trust, shall execute proper 
instruments acknowledging satisfaction and discharge of this Indenture as to 
such series when

         (1)  either

              (A)  all Securities of such series theretofore authenticated 
         and delivered and all coupons, if any, appertaining thereto (other 
         than (i) coupons appertaining to Bearer Securities surrendered for 
         exchange for Registered Securities and maturing after such exchange, 
         whose surrender is not required or has been waived as provided in

         305, (ii) Securities and coupons of such series which have been 
         destroyed, lost or stolen and which have been replaced or paid as 
         provided in Section 306, (iii) coupons appertaining to Securities 
         called for redemption and maturing after the relevant Redemption 
         Date, whose surrender has been waived as provided in Section 1106, 
         and (iv) Securities and coupons of such series for whose payment 
         money has theretofore been deposited in trust or segregated and held

         discharged from such trust, as provided in Section 1003) have been 
         delivered to the Trustee for cancellation; or

              (B)  all Securities of such series and, in the case of (i) or 
         (ii) below, any coupons appertaining thereto not theretofore 
         delivered to the Trustee for cancellation

                   (i)  have become due and payable, or

                  (ii)  will become due and payable at their Stated Maturity
              within one year, or

                 (iii)  if redeemable at the option of the Trust, are to be
              called for redemption within one year under arrangements
              satisfactory to the Trustee for the giving of notice of
              redemption by the Trustee in the name, and at the expense, of the
              Trust,

         and the Trust, in the case of (i), (ii) or (iii) above, has 
         irrevocably deposited or caused to be deposited with the Trustee as 
         trust funds in trust for the purpose an amount in the currency or 
         currencies, currency unit or units or composite currency or 
         currencies in which the Securities of such series are payable, 
         sufficient to pay and discharge the entire indebtedness on such 
         Securities and such coupons not theretofore delivered to the Trustee 
         for cancellation, for principal (and premium, if any) and interest, 
         and any Additional Amounts with respect thereto, to the date of such 
         deposit (in the case of Securities which have become due and 
         payable) or to the Stated Maturity or Redemption Date, as the case 
         may be;

         (2)  the Trust has paid or caused to be paid all other sums payable
    hereunder by the Trust; and

         (3)  the Trust has delivered to the Trustee an Officer's Certificate
    and an Opinion of Counsel, each stating that all conditions precedent
    herein provided for relating to the satisfaction and discharge of this
    Indenture as to such series have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the 
obligations of the Trust to the Trustee and any predecessor Trustee under 
Section 606, the obligations of the Trust to any Authenticating Agent under 
Section 611 and, if money shall have been deposited with and held by

the Trustee pursuant to subclause (B) of clause (1) of this Section, the 
obligations of the Trustee under Section 402 and the last paragraph of 
Section 1003 shall survive.

         SECTION 402.  Application of Trust Funds.   Subject to the 
provisions of the last paragraph of Section 1003, all money deposited with 
the Trustee pursuant to Section 401 shall be held in trust and applied by it, 
in accordance with the provisions of the Securities, the coupons and this 
Indenture, to the payment, either directly or through any Paying Agent 
(including the Trust acting as its own Paying Agent) as the Trustee may 
determine, to the Persons entitled thereto, of the principal (and premium, if 
any), and any interest and Additional Amounts for whose payment such money 
has been deposited with or received by the Trustee, but such money need not 
be segregated from other funds except to the extent required by law.

                                       REMEDIES

         SECTION 501.  Events of Default.  "Event of Default", wherever used 
herein with respect to any particular series of Securities, means any one of 
the following events (whatever the reason for such Event of Default and 
whether or not 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):

          (1)  default in the payment of any interest upon or any Additional 
    Amounts payable in respect of any Security of that series or of any 
    coupon appertaining thereto, when such interest, Additional Amounts or 
    coupon becomes due and payable, and continuance of such default for a 
    period of 30 days; or

         (2)  default in the payment of the principal of (or premium, if any, 
    on) any Security of that series when it becomes due and payable at its 
    Maturity; or

         (3)  default in the deposit of any sinking fund payment, when and as 
    due by the terms of any Security of that series; or 

         (4)  default in the performance, or breach, of any covenant or 
    warranty of the Trust in this Indenture with respect to any Security of 
    that series (other than a covenant or warranty a default in whose 
    performance or whose breach is elsewhere in this Section specifically 
    dealt with), and continuance of such default or breach for a period of 60 
    days after there has been given, by registered or certified mail, to the 
    Trust by the Trustee or to the Trust and the Trustee by the Holders of at 
    least 25% in principal amount of the Outstanding Securities of that 
    series a written notice specifying such default or breach and requiring 
    it to be remedied and stating that such notice is a "Notice of Default" 
    hereunder; or 
                                      -36-

<PAGE>

         (5)  default under any bond, debenture, note or other evidence of 
    indebtedness for money borrowed by the Trust (including obligations under 
    leases required to be capitalized on the balance sheet of the lessee 
    under generally accepted accounting principles, but not including any 
    indebtedness or obligations for which recourse is limited to property 
    purchased) in an aggregate principal amount in excess of $5,000,000 or 
    under any mortgage, indenture or instrument under which there may be 
    issued or by which there may be secured or evidenced any indebtedness for 
    money borrowed by the Trust (including such leases but not including such 
    indebtedness or obligations for which recourse is limited to property 
    purchased) in an aggregate principal amount in excess of $5,000,000 by 
    the Trust, whether such indebtedness now exists or shall hereafter be 
    created, which default shall have resulted in such indebtedness becoming 
    or being declared due and payable prior to the date on which it would 
    otherwise have become due and payable or such obligations being 
    accelerated, without such acceleration having been rescinded or annulled; 
    or 

         (6)  the Trust or any Significant Subsidiary pursuant to or within 
    the meaning of any Bankruptcy Law:

              (A)  commences a voluntary case,

              (B)  consents to the entry of an order for relief against it in
         an involuntary case,

              (C)  consents to the appointment of a Custodian of it or for all
         or substantially all of its property, or

              (D)  makes a general assignment for the benefit of its creditors;
         or

         (7)  a court of competent jurisdiction enters an order or decree under
    any Bankruptcy Law that:

              (A)  is for relief against the Trust or any Significant 
         Subsidiary in an involuntary case,

              (B)  appoints a Custodian of the Trust or any Significant
         Subsidiary or for all or substantially all of either of its property,
         or

              (C)  orders the liquidation of the Trust or any Significant
         Subsidiary,

    and the order or decree remains unstayed and in effect for 90 days; or

         (8)  any other Event of Default provided with respect to Securities of
    that series.
                                      -37-

<PAGE>

 As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. 
Code or any similar Federal or State law for the relief of debtors and the 
term "Custodian" means any receiver, trustee, assignee, liquidator or other 
similar official under any Bankruptcy Law.

         SECTION 502.  Acceleration of Maturity; Rescission and Annulment.  
If an Event of Default with respect to Securities of any series at the time 
Outstanding 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 
Securities of that series may declare the principal (or, if any Securities 
are Original Issue Discount Securities or Indexed Securities, such portion of 
the principal as may be specified in the terms thereof) of all the Securities 
of that series to be due and payable immediately, by a notice in writing to 
the Trust (and to the Trustee if given by the Holders), and upon any such 
declaration such principal or specified portion thereof shall become 
immediately due and payable.

         At any time after such a declaration of acceleration with respect to 
Securities of any series 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 Securities of that series, by written notice to the Trust and the 
Trustee, may rescind and annul such declaration and its consequences if:

         (1)  the Trust has paid or deposited with the Trustee a sum sufficient
    to pay in the currency or currency unit or composite currency in which the
    Securities of such series are payable (except as otherwise specified
    pursuant to Section 301 for the Securities of such series):

              (A)  all overdue installments of interest on and any Additional
         Amounts payable in respect of all Outstanding Securities of that
         series and any related coupons,

              (B)  the principal of (and premium, if any, on) any Outstanding
         Securities of that series which have become due otherwise than by such
         declaration of acceleration and interest thereon at the rate or rates
         borne by or provided for in such Securities,

              (C)  to the extent that payment of such interest is lawful,
         interest upon overdue installments of interest and any Additional
         Amounts at the rate or rates borne by or provided for in such
         Securities, and

              (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

         (2)  all Events of Default with respect to Securities of that series,
    other than the nonpayment of the principal of (or premium, if any) or
    interest on Securities of that series

                                      -38-

<PAGE>

    which have become due solely by such declaration of acceleration, have 
    been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right 
consequent thereon.

         SECTION 503.  Collection of Indebtedness and Suits for Enforcement by
Trustee.  The Trust covenants that if:

         (1)  default is made in the payment of any installment of interest or
    Additional Amounts, if any, on any Security of any series and any related
    coupon when such interest or Additional Amount becomes due and payable and
    such default continues for a period of 30 days, or

         (2)  default is made in the payment of the principal of (or premium,
    if any, on) any Security of any series at its Maturity,

then the Trust will, upon demand of the Trustee, pay to the Trustee, for the 
benefit of the Holders of such Securities of such series and coupons, the 
whole amount then due and payable on such Securities and coupons for 
principal (and premium, if any) and interest and Additional Amounts, with 
interest upon any overdue principal (and premium, if any) and, to the extent 
that payment of such interest shall be legally enforceable, upon any overdue 
installments of interest or Additional Amounts, if any, at the rate or rates 
borne by or provided for in such Securities, and, in addition thereto, such 
further amount as shall be sufficient to cover the costs and expenses of 
collection, including the reasonable compensation, expenses, disbursements 
and advances of the Trustee, its agents and counsel.

         If the Trust 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 judgment or final decree, and 
may enforce the same against the Trust or any other obligor upon such 
Securities of such series and collect the moneys adjudged or decreed to be 
payable in the manner provided by law out of the property of the Trust or any 
other obligor upon such Securities of such series, wherever situated.

         If an Event of Default with respect to Securities of any series 
occurs and is continuing, the Trustee may in its discretion proceed to 
protect and enforce its rights and the rights of the Holders of Securities of 
such series and any related coupons 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 504.  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 Trust or any other obligor upon the Securities


                                      -39-

<PAGE>

or the property of the Trust or of such other obligor or their creditors, the 
Trustee (irrespective of whether the principal of the Securities of any 
series 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 Trust for the payment of overdue principal, premium, if any, or 
interest) shall be entitled and empowered, by intervention in such proceeding 
or otherwise:

         (i)  to file and prove a claim for the whole amount, or such lesser
    amount as may be provided for in the Securities of such series, of
    principal (and premium, if any) and interest and Additional Amounts, if
    any, owing and unpaid in respect of the Securities and to file such other
    papers or documents as may be necessary or advisable in order to have the
    claims of the Trustee (including any claim for the reasonable compensation,
    expenses, disbursements and advances of the Trustee, its agents and
    counsel) and of the Holders allowed in such judicial proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or 
other similar official) in any such judicial proceeding is hereby authorized 
by each Holder of Securities of such series and coupons to make such payments 
to the Trustee, 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 for the reasonable compensation, expenses, disbursements and 
advances of the Trustee and any predecessor Trustee, their agents and 
counsel, and any other amounts due the Trustee or any predecessor Trustee 
under Section 606.

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

         SECTION 505.  Trustee May Enforce Claims Without Possession of 
Securities or Coupons.  All rights of action and claims under this Indenture 
or any of the Securities or coupons may be prosecuted and enforced by the 
Trustee without the possession of any of the Securities or coupons 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 judgment shall, after 
provision for the payment of the reasonable compensation, expenses, 
disbursements and advances of the Trustee, its agents and counsel, be for the 
ratable benefit of the Holders of the Securities and coupons in respect of 
which such judgment has been recovered.

         SECTION 506.  Application of Money Collected.  Any money collected 
by the Trustee pursuant to this Article shall be applied in the following 
order, at the date or dates fixed by the


                                      -40-

<PAGE>

Trustee and, in case of the distribution of such money on account of 
principal (or premium, if any) or interest and any Additional Amounts, upon 
presentation of the Securities or coupons, or both, as the case may be, 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 606;

         SECOND:  To the payment of the amounts then due and unpaid upon the
    Securities and coupons for principal (and premium, if any) and interest and
    any Additional Amounts payable, 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 aggregate amounts due and payable on
    such Securities and coupons for principal (and premium, if any), interest
    and Additional Amounts, respectively; and

         THIRD:  To the payment of the remainder, if any, to the Trust.

         SECTION 507.  Limitation on Suits.  No Holder of any Security of any 
series or any related coupon shall have any right to institute any 
proceeding, judicial or otherwise, with respect to this Indenture, or for the 
appointment of a receiver or trustee, or for any other remedy hereunder, 
unless:

         (1)  such Holder has previously given written notice to the Trustee of
    a continuing Event of Default with respect to the Securities of that
    series;

         (2)  the Holders of not less than 25% in principal amount of the
    Outstanding Securities of that series 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;

         (3)  such Holder or Holders have offered to the Trustee indemnity
    reasonably satisfactory to the Trustee against the costs, expenses and
    liabilities to be incurred in compliance with such request;

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

         (5)  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 Securities of that series;

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 of
such Holders, or to obtain or to seek to obtain priority or

                                      -41-

<PAGE>

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 508.  Unconditional Right of Holders to Receive Principal, 
Premium, if any, Interest and Additional Amounts.  Notwithstanding any other 
provision in this Indenture, the Holder of any Security or coupon shall have 
the right which is absolute and unconditional to receive payment of the 
principal of (and premium, if any) and subject to Sections 305 and 307, 
interest on, and any Additional Amounts in respect of, such Security or 
payment of such coupon on the respective due dates expressed in such Security 
or coupon (or, in the case of redemption, on the Redemption Date) and to 
institute suit for the enforcement of any such payment, and such rights shall 
not be impaired without the consent of such Holder.

         SECTION 509. Restoration of Rights and Remedies.  If the Trustee or 
any Holder of a Security of coupon 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 Trust, the 
Trustee and the Holders of Securities and coupons shall, subject to and 
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 510.  Rights and Remedies Cumulative.  Except as otherwise 
provided with respect to the replacement or payment of mutilated, destroyed, 
lost or stolen Securities or coupons in the last paragraph of Section 306, no 
right or remedy herein conferred upon or reserved to the Trustee or to the 
Holders of Securities or coupons 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 511.  Delay or Omission Not Waiver.  No delay or omission of 
the Trustee or of any Holder of any Security or coupon 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 of Securities or 
coupons, as the case may be.

         SECTION 512.  Control by Holders of Securities.  The Holders of not 
less than a majority in principal amount of the Outstanding Securities of any 
series 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 
Securities of such series, provided that


                                      -42-

<PAGE>

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

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

         (3)  the Trustee need not take any action which might involve it in
    personal liability or be unduly prejudicial to the Holders of Securities of
    such series not joining therein.

         SECTION 513.  Waiver of Past Defaults.  The Holders of not less than 
a majority in principal amount of the Outstanding Securities of any series 
may on behalf of the Holders of all the Securities of such series and any 
related coupons waive any past default hereunder with respect to such series 
and its consequences, except a default

         (1)  in the payment of the principal of (or premium, if any) or
    interest on or Additional Amounts payable in respect of any Security of
    such series or any related coupons, or

         (2)  in respect of a covenant or provision hereof which under Article
    Nine cannot be modified or amended without the consent of the Holder of
    each Outstanding Security of such series affected.

         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 Event of Default or impair any right consequent thereon.

         SECTION 514.  Waiver of Usury, Stay or Extension Laws.  The Trust 
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 Trust (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.

         SECTION 515.  Undertaking for Costs.  All parties to this Indenture 
agree, and each Holder of any Security 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 any undertaking to 
pay the costs of such suit, and that such court may in its discretion assess 
reason-able costs, including reasonable attorneys' fees, against any party 
litigant in such suit having due regard to the merits and good faith of the 
claims or defenses made


                                      -43-

<PAGE>
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 Securities, or to any suit instituted by any Holder 
for the enforcement of the payment of the principal of (or premium, if any) 
or interest on any Security on or after the respective Stated Maturities 
expressed in such Security (or, in the case of redemption, on or after the 
Redemption Date).


                                     ARTICLE SIX

                                     THE TRUSTEE

         SECTION 601.  Notice of Defaults.  Within 90 days after the 
occurrence of any default hereunder with respect to the Securities of any 
series, the Trustee shall transmit in the manner and to the extent provided 
in TIA Section 313(c), 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 on or any Additional Amounts with respect to any 
Security of such series, or in the payment of any sinking fund installment 
with respect to the Securities of such series, the Trustee shall be protected 
in withholding such notice if and so long as Responsible Officers of the 
Trustee in good faith determine that the withholding of such notice is in the 
interests of the Holders of the Securities and coupons of such series; and 
provided further that in the case of any default or breach of the character 
specified in Section 501(4) with respect to the Securities and coupons of 
such series, no such notice to Holders shall be given until at least 60 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 with respect to the Securities of such 
series.

of TIA Section 315(a) through 315(d):

         (1)  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, note, coupon or other paper or document believed by it to
    be genuine and to have been signed or presented by the proper party or
    parties;

         (2)  any request or direction of the Trust mentioned herein shall be
    sufficiently evidenced by a Trust Request or Trust Order (other than
    delivery of any Security, together with any coupons appertaining thereto,
    to the Trustee for authentication and delivery pursuant to Section 303
    which shall be sufficiently evidenced as provided therein) and any
    resolution of the Board of Trustees may be sufficiently evidenced by a
    Board Resolution;

    taking, suffering or omitting any action


                                      -44-

<PAGE>

    hereunder, the Trustee (unless other evidence be herein specifically 
    prescribed) may, in the absence of bad faith on its part, rely upon an 
    Officers' Certificate;

         (4)  the Trustee may consult with counsel 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;

         (5)  the Trustee shall be under no obligation to exercise any of the
    rights or powers vested in it by this Indenture at the request or direction
    of any of the Holders of Securities of any series or any related coupons
    pursuant to this Indenture, unless such Holders shall have offered to the
    Trustee security or indemnity reasonably satisfactory to the Trustee
    against the costs, expenses and liabilities which might be incurred by it
    in compliance with such request or direction;

         (6)  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, debenture, note, coupon or other paper or document, but the Trustee,
    in its discretion, may make such further inquiry or investigation into such
    facts or matters as it may see fit, and, if the Trustee shall determine to
    make such further inquiry or investigation, it shall be entitled to make
    reasonable examination of the books, records and premises of the Trust,
    personally or by agent or attorney following reasonable notice to the
    Trust;

         (7)  the Trustee may execute any of the trusts or powers hereunder or
    perform any duties hereunder either directly or by or through agents or
    attorneys and the Trustee shall not be responsible for any misconduct or
    negligence on the part of any agent or attorney appointed with due care by
    it hereunder; and

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

         The Trustee shall not be required 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 it 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.

         Except during the continuance of an Event of Default, the Trustee
undertakes to perform 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.

          SECTION 603.  Not Responsible for Recitals or Issuance of 
Securities. The recitals contained herein and in the Securities, except the 
Trustee's certificate of authentication, and in any


                                      -45-

<PAGE>

coupons shall be taken as the statements of the Trust, and neither the 
Trustee nor any Authenticating Agent assumes any responsibility for their 
correctness.  The Trustee makes no representations as to the validity or 
sufficiency of this Indenture or of the Securities or coupons, except that 
the Trustee represents that it is duly authorized to execute and deliver this 
Indenture, authenticate the Securities and perform its obligations hereunder. 
 Neither the Trustee nor any Authenticating Agent shall be accountable for 
the use or application by the Trust of Securities or the proceeds thereof.

         SECTION 604.  May Hold Securities.  The Trustee, any Paying Agent, 
Security Registrar, Authenticating Agent or any other agent of the Trust, in 
its individual or any other capacity, may become the owner or pledgee of 
Securities and coupons and, subject to TIA Sections 310(b) and 311, may 
otherwise deal with the Trust with the same rights it would have if it were 
not Trustee, Paying Agent, Security Registrar, Authenticating Agent or such 
other agent.

         SECTION 605.  Money Held in Trust.  Money held by the Trustee in 
trust hereunder need not be segregated from other funds except to the extent 
required by law.  The Trustee shall be under no liability for interest on any 
money received by it hereunder except as otherwise agreed with the Trust.

         SECTION 606.  Compensation and Reimbursement.  The Trust agrees:

         (1)  to pay to the Trustee from time to time reasonable compensation
    for all services rendered by it hereunder (which compensation shall not be
    limited by any provision of law in regard to the compensation of a trustee
    of an express trust);

         (2)  except as otherwise expressly provided herein, to reimburse each
    of the Trustee and any predecessor 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, disbursement or advance as may be
    attributable to its negligence or bad faith; and

         (3)  to indemnify each of the Trustee and any predecessor Trustee for,
    and to hold it harmless against, any loss, liability or expense incurred
    without negligence or bad faith on its own part, arising out of or in
    connection with the acceptance or administration of the trust or trusts
    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.

         When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(6) or Section 501(7), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

                                      -46-

<PAGE>

         As security for the performance of the obligations of the Trust under
this Section, the Trustee shall have a lien prior to the Securities upon all
property and funds held or collected by the Trustee as such, except funds held
in trust for the payment of principal of (or premium, if any) or interest on
particular Securities or any coupons.

         The provisions of this Section shall survive the termination of this
Indenture.

         SECTION 607.  Corporate Trustee Required; Eligibility; Conflicting 
Interests.  There shall at all times be a Trustee hereunder which shall be 
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a 
combined capital and surplus of at least $50,000,000.  If such corporation 
publishes reports of condition at least annually, pursuant to law or the 
requirements of Federal, State, Territorial or District of Columbia 
supervising or examining authority, then for 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.

         SECTION 608.  Resignation and Removal; Appointment of Successor.  
(a) No resignation or removal of the Trustee and no appointment of a 
successor Trustee pursuant to this Article shall become effective until the 
acceptance of appointment by the successor Trustee in accordance with the 
applicable requirements of Section 609.

         (b)  The Trustee may resign at any time with respect to the 
Securities of one or more series by giving written notice thereof to the 
Trust.  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 with respect to the 
Securities of any series by Act of the Holders of a majority in principal 
amount of the Outstanding Securities of such series delivered to the Trustee 
and to the Trust.

         (d)  If at any time:

         (1)  the Trustee shall fail to comply with the provisions of TIA
    Section 310(b) after written request therefor by the Trust or by any Holder
    of a Security who has been a bona fide Holder of a Security for at least
    six months, or

         (2)  the Trustee shall cease to be eligible under Section 607 and
    shall fail to resign after written request therefor by the Trust or by any
    Holder of a Security who has been a bona fide Holder of a Security for at
    least six months, or


                                      -47-

<PAGE>


         (3)  the Trustee shall become incapable of acting or shall be adjudged
    a bankrupt or insolvent or a receiver of the Trustee or of its property
    shall be appointed or any public officer shall take charge or control of
    the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation,

then, in any such case, (i) the Trust by or pursuant to a Board Resolution 
may remove the Trustee and appoint a successor Trustee with respect to all 
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security 
who has been a bona fide Holder of a Security for at least six months may, on 
behalf of himself and all others similarly situated, petition any court of 
competent jurisdiction for the removal of the Trustee with respect to all 
Securities and the appointment of a successor Trustee or Trustees.

         (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 Securities of one or more series, the Trust, by or 
pursuant to a Board Resolution, shall promptly appoint a successor Trustee or 
Trustees with respect to the Securities of that or those series (it being 
understood that any such successor Trustee may be appointed with respect to 
the Securities of one or more or all of such series and that at any time 
there shall be only one Trustee with respect to the Securities of any 
particular series).  If, within one year after such resignation, removal or 
incapability, or the occurrence of such vacancy, a successor Trustee with 
respect to the Securities of any series shall be appointed by Act of the 
Holders of a majority in principal amount of the Outstanding Securities of 
such series delivered to the Trust and the retiring Trustee, the successor 
Trustee so appointed shall, forthwith upon its acceptance of such 
appointment, become the successor Trustee with respect to the Securities of 
such series and to that extent supersede the successor Trustee appointed by 
the Trust.  If no successor Trustee with respect to the Securities of any 
series shall have been so appointed by the Trust or the Holders of Securities 
and accepted appointment in the manner hereinafter provided, any Holder of a 
Security who has been a bona fide Holder of a Security of such series for at 
least six months may, on behalf of himself and all others similarly situated, 
petition any court of competent jurisdiction for the appointment of a 
successor Trustee with respect to Securities of such series.

         (f)  The Trust shall give notice of each resignation and each 
removal of the Trustee with respect to the Securities of any series and each 
appointment of a successor Trustee with respect to the Securities of any 
series in the manner provided for notices to the Holders of Securities in 
Section 106.  Each notice shall include the name of the successor Trustee 
with respect to the Securities of such series and the address of its 
Corporate Trust Office.

         SECTION 609.  Acceptance of Appointment by Successor.  (a)  In case 
of the appointment hereunder of a successor Trustee with respect to all 
Securities, every such successor Trustee shall execute, acknowledge and 
deliver to the Trust and to the retiring Trustee an instrument accepting such 
appointment, and thereupon the resignation or removal of the retiring Trustee 
shall become effective and such successor Trustee, without any further act, 
deed or conveyance, shall become vested with all the rights, powers, trusts 
and duties of the retiring Trustee; but, on request of the Trust or the 
successor Trustee, such retiring Trustee shall, upon payment of its charges, 


                                      -48-

<PAGE>

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, subject nevertheless to its claim, if any, 
provided for in Section 606.

         (b)  In case of the appointment hereunder of a successor Trustee 
with respect to the Securities of one or more (but not all) series, the 
Trust, the retiring Trustee and each successor Trustee with respect to the 
Securities of one or more series shall execute and deliver an indenture 
supplemental hereto, pursuant to Article Nine hereof, wherein each successor 
Trustee shall accept such appointment and which (1) shall contain such 
provisions as shall be necessary or desirable to transfer and confirm to, and 
to vest in, each successor Trustee all the rights, powers, trusts and duties 
of the retiring Trustee with respect to the Securities of that or those 
series to which the appointment of such successor Trustee relates, (2) if the 
retiring Trustee is not retiring with respect to all Securities, shall 
contain such provisions as shall be deemed necessary or desirable to confirm 
that all the rights, powers, trusts and duties of the retiring Trustee with 
respect to the Securities of that or those series as to which the retiring 
Trustee is not retiring shall continue to be vested in the retiring Trustee, 
and (3) shall add to or change any of the provisions of this Indenture as 
shall be necessary to provide for or facilitate the administration of the 
trusts hereunder by more than one Trustee, it being understood that nothing 
herein or in such supplemental indenture shall constitute such Trustees 
co-trustees of the same trust and that each such Trustee shall be trustee of 
a trust or trusts hereunder separate and apart from any trust or trusts 
hereunder administered by any other such Trustee; and upon the execution and 
delivery of such supplemental indenture the resignation or removal of the 
retiring Trustee shall become effective to the extent provided therein and 
each 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 with respect to the Securities of that or those series to 
which the appointment of such successor Trustee relates; but, on request of 
the Trust or any successor Trustee, such retiring Trustee shall duly assign, 
transfer and deliver to such successor Trustee all property and money held by 
such retiring Trustee hereunder with respect to the Securities of that or 
those series to which the appointment of such successor Trustee relates.

         (c)  Upon request of any such successor Trustee, the Trust shall 
execute any and all instruments for more fully and certainly vesting in and 
confirming to such successor Trustee all such rights, powers and trusts 
referred to in paragraph (a) or (b) of this Section, as the case may be.

         (d)  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 610.  Merger, Conversion, Consolidation or Succession to 
Business.  Any corporation into which the 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


                                      -49-

<PAGE>

filing of any paper or any further act on the part of any of the parties 
hereto.  In case any Securities or coupons 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 Securities or coupons so authenticated with 
the same effect as if such successor Trustee had itself authenticated such 
Securities or coupons.  In case any Securities or coupons shall not have been 
authenticated by such predecessor Trustee, any such successor Trustee may 
authenticate and deliver such Securities or coupons, in either its own name 
or that of its predecessor Trustee, with the full force and effect which this 
Indenture provides for the certificate of authentication of the Trustee.

          SECTION 611.  Appointment of Authenticating Agent.  At any time 
when any of the Securities remain Outstanding, the Trustee may appoint an 
Authenticating Agent or Agents with respect to one or more series of 
Securities which shall be authorized to act on behalf of the Trustee to 
authenticate Securities of such series issued upon exchange, registration of 
transfer or partial redemption or repayment thereof, and Securities 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.  Any such appointment shall be evidenced by an instrument in 
writing signed by a Responsible Officer of the Trustee, a copy of which 
instrument shall be promptly furnished to the Trust.  Wherever reference is 
made in this Indenture to the authentication and delivery of Securities 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 and a certificate of authentication 
executed on behalf of the Trustee by an Authenticating Agent.  Each 
Authenticating Agent shall be acceptable to the Trust and shall at all times 
be a bank or trust company or corporation organized and doing business and in 
good standing under the laws of the United States of America or of any State 
or the District of Columbia, authorized under such laws to act as 
Authenticating Agent, having a combined capital and surplus of not less than 
$50,000,000 and subject to supervision or examination by Federal or State 
authorities.  If such Authenticating Agent publishes reports of condition at 
least annually, pursuant to law or the requirements of the aforesaid 
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.  In case 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 the corporate agency 
or corporate trust business of an Authenticating Agent, shall continue to be 
an Authenticating Agent, provided such corporation shall be otherwise 
eligible under this Section, without the execution or filing of any paper or 
further act on the part of the Trustee or the Authenticating Agent.

                                      -50-

<PAGE>

         An Authenticating Agent for any series of Securities may at any time 
resign by giving written notice of resignation to the Trustee for such series 
and to the Trust.  The Trustee for any series of Securities may at any time 
terminate the agency of an Authenticating Agent by giving written notice of 
termination to such Authenticating Agent and to the Trust.  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 for such series may appoint a 
successor Authenticating Agent which shall be acceptable to the Trust and 
shall give notice of such appointment to all Holders of Securities of the 
series with respect to which such Authenticating Agent will serve in the 
manner set forth in Section 106.  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 herein.  No successor 
Authenticating Agent shall be appointed unless eligible under the provisions 
of this Section.

         The Trust agrees to pay to each Authenticating Agent from time to 
time reasonable compensation including reimbursement of its reasonable 
expenses for its services under this Section.

         If an appointment with respect to one or more series is made 
pursuant to this Section, the Securities of such series may have endorsed 
thereon, in addition to or in lieu of the Trustee's certificate of 
authentication, an alternate certificate of authentication substantially in 
the following form:

         This is one of the Securities of the series designated therein 
referred to in the within-mentioned Indenture.

                           _______________________________,
                               as Trustee

    regulations prescribe) which the Trust may be required to file with the
    Commission pursuant to Section 13 or Section 15(d) of the Securities
    Exchange Act of 1934; or, if the Trust is not required to file information,

    time to time by the Commission, such of the supplementary and periodic

such list shall be required to be furnished.

         SECTION 801.  Consolidations and Mergers of Trust and Sales, Leases
and Conveyances Permitted Subject to Certain Conditions.  The Trust may
consolidate with, or sell, lease or convey all or substantially all of its
assets to, or merge with or into any other corporation, provided that in any
such case, (1) either the Trust shall be the continuing corporation, or the
successor corporation shall be a corporation organized and existing under the
laws of the United States or a State thereof and such successor corporation
shall expressly assume the due and punctual payment of the principal of (and
premium, if any) and any interest (including all Additional Amounts, if any,
payable pursuant to Section 1010) on all of the Securities, according to their

supplemental indenture, complying with Article Nine hereof, satisfactory to the
Trustee, executed and delivered to the Trustee by such corporation and (2)
immediately after giving effect to such transaction and treating any

any such consolidation, merger, sale, lease or conveyance and upon any such
assumption by the successor corporation, such successor corporation shall
succeed to and be substituted for the Trust, with the same effect as if it had

corporation, except in the event of a lease, shall be relieved of any further
obligation under this

Indenture and the Securities.  Such successor corporation thereupon may cause 
to be signed, and may issue either in its own name or in the name of the 
Trust, any or all of the Securities issuable hereunder which theretofore 
shall not have been signed by the Trust and delivered to the Trustee; and, 
upon the order of such successor corporation, instead of the Trust, and 
subject to all the terms, conditions and limitations in this Indenture 
prescribed, the Trustee shall authenticate and shall deliver any Securities 
which previously shall have been signed and delivered by the officers of the 
Trust to the Trustee for authentication, and any Securities which such 
successor corporation thereafter shall cause to be signed and delivered to 
the Trustee for that purpose.  All the Securities so issued shall in all 
respects have the same legal rank and benefit under this Indenture as the 
Securities theretofore or thereafter issued in accordance with the terms of 
this Indenture as though all of such Securities had been issued at the date 
of the execution hereof.

         In case of any such consolidation, merger, sale, lease or conveyance,
such changes in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

         SECTION 803.  Officer's Certificate and Opinion of Counsel.  Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officer's Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor corporation,
complies with the provisions of this Article and that all conditions precedent
herein provided for relating to such transaction have been complied with.

                               SUPPLEMENTAL INDENTURES

         SECTION 901.  Supplemental Indentures without Consent of Holders. 
Without the consent of any Holders of Securities or coupons, the Trust, when
authorized by or pursuant to a Board Resolution, and the Trustee, at any time
and from time to time, may enter into one or more indentures supplemental
hereto, in form satisfactory to the Trustee, for any of the following purposes:

         (1)  to evidence the succession of another Person to the Trust and the
    assumption by any such successor of the covenants of the Trust herein and
    in the Securities contained; or

         (2)  to add to the covenants of the Trust for the benefit of the
    Holders of all or any series of Securities (and if such covenants are to be
    for the benefit of less than all series of Securities, stating that such
    covenants are expressly being included solely for the benefit of such
    series) or to surrender any right or power herein conferred upon the Trust;
    or


                                    -54-


<PAGE>


         (3)  to add any additional Events of Default for the benefit of the
    Holders of all or any series of Securities (and if such Events of Default
    are to be for the benefit of less than all series of Securities, stating
    that such Events of Default are expressly being included solely for the
    benefit of such series); provided, however, that in respect of any such
    additional Events of Default such supplemental indenture may provide for a
    particular period of grace after default (which period may be shorter or
    longer than that allowed in the case of other defaults) or may provide for
    an immediate enforcement upon such default or may limit the remedies
    available to the Trustee upon such default or may limit the right of the
    Holders of a majority in aggregate principal amount of that or those series
    of Securities to which such additional Events of Default apply to waive
    such default; or

         (4)  to add to or change any of the provisions of this Indenture to
    provide that Bearer Securities may be registrable as to principal, to
    change or eliminate any restrictions on the payment of principal of or any
    premium or interest on Bearer Securities, to permit Bearer Securities to be
    issued in exchange for Registered Securities, to permit Bearer Securities
    to be issued in exchange for Bearer Securities of other authorized
    denominations or to permit or facilitate the issuance of Securities in
    uncertificated form, provided that any such action shall not adversely
    affect the interests of the Holders of Securities of any series or any
    related coupons in any material respect; or 

         (5)  to change or eliminate any of the provisions of this Indenture,
    provided that any such change or elimination shall become effective only
    when there is no Security Outstanding of any series created prior to the
    execution of such supplemental indenture which is entitled to the benefit
    of such provision; or

         (6)  to secure the Securities; or

         (7)  to establish the form or terms of Securities of any series and
    any related coupons as permitted by Sections 201 and 301, including the
    provisions and procedures relating to Securities convertible into Common
    Shares or Preferred Shares, as the case may be; or

         (8)  to evidence and provide for the acceptance of appointment
    hereunder by a successor Trustee with respect to the Securities of one or
    more series and to add to or change any of the provisions of this Indenture
    as shall be necessary to provide for or facilitate the administration of
    the trusts hereunder by more than one Trustee; or

         (9)  to cure any ambiguity, to correct or supplement any provision
    herein which may be defective or inconsistent with any other provision
    herein, or to make any other provisions with respect to matters or
    questions arising under this Indenture which shall not be inconsistent with
    the provisions of this Indenture, provided such provisions shall not
    adversely affect the interests of the Holders of Securities of any series
    or any related coupons in any material respect; or


                                    -55-


<PAGE>


          (10)     to supplement any of the provisions of this Indenture to
    such extent as shall be necessary to permit or facilitate the defeasance
    and discharge of any series of Securities pursuant to Sections 401, 1402
    and 1403; provided that any such action shall not adversely affect the
    interests of the Holders of Securities of such series and any related
    coupons or any other series of Securities in any material respect.

         SECTION 902.  Supplemental Indentures with Consent of Holders.  With
the consent of the Holders of not less than a majority in principal amount of
all Outstanding Securities affected by such supplemental indenture, by Act of
said Holders delivered to the Trust and the Trustee, the Trust, when authorized
by or pursuant to a Board Resolution, and the Trustee may enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Indenture or of modifying in any manner the rights of the Holders of
Securities and any related coupons under this Indenture; provided, however, that
no such supplemental indenture shall, without the consent of the Holder of each
Outstanding Security affected thereby:

         (1)  change the Stated Maturity of the principal of (or premium, if
    any, on) or any installment of principal of or interest on, any Security;
    or reduce the principal amount thereof or the rate or amount of interest
    thereon or any Additional Amounts payable in respect thereof, or any
    premium payable upon the redemption thereof, or change any obligation of
    the Trust to pay Additional Amounts pursuant to Section 1010 (except as
    contemplated by Section 801(1) and permitted by Section 901(1)), or reduce
    the amount of the principal of an Original Issue Discount Security that
    would be due and payable upon a declaration of acceleration of the Maturity
    thereof pursuant to Section 502 or the amount thereof provable in
    bankruptcy pursuant to Section 504, or adversely affect any right of
    repayment at the option of the Holder of any Security, or change any Place
    of Payment where, or the currency or currencies, currency unit or units or
    composite currency or currencies in which, any Security or any premium or
    the interest thereon is payable, or impair the right to institute suit for
    the enforcement of any such payment on or after the Stated Maturity thereof
    (or, in the case of redemption or repayment at the option of the Holder, on
    or after the Redemption Date or the Repayment Date, as the case may be), or 

         (2)  reduce the percentage in principal amount of the Outstanding
    Securities of any series, the consent of whose Holders is required for any
    such supplemental indenture, or the consent of whose Holders is required
    for any waiver with respect to such series (or compliance with certain
    provisions of this Indenture or certain defaults hereunder and their
    consequences) provided for in this Indenture, or reduce the requirements of
    Section 1504 for quorum or voting, or

         (3)  modify any of the provisions of this Section, Section 513 or
    Section 1013, except to increase the required percentage to effect such
    action or to provide that certain other provisions of this Indenture cannot
    be modified or waived without the consent of the Holder of each Outstanding
    Security affected thereby.

         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.

         A supplemental indenture which changes or eliminates any covenant or
other provision of this Indenture which has expressly been included solely for
the benefit of one or more particular series of Securities, or which modifies
the rights of the Holders of Securities of such series with respect to such
covenant or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

         SECTION 903.  Execution of Supplemental Indentures.  In executing, or
accepting the additional trusts created by, any supplemental indenture permitted
by this Article or the  modification thereby of the trusts created by this
Indenture, the Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture.  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 904.  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 Securities
theretofore or thereafter authenticated and delivered hereunder and of any
coupon appertaining thereto shall be bound thereby.

         SECTION 905.  Conformity with Trust Indenture Act.  Every supplemental
indenture executed pursuant to this Article shall conform to the requirements of
the Trust Indenture Act as then in effect.

         SECTION 906.  Reference in Securities to Supplemental Indentures. 
Securities of any series 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 Trust shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Trust, to any such supplemental indenture may be prepared and
executed by the Trust and authenticated and delivered by the Trustee in exchange
for Outstanding Securities of such series.


                                     ARTICLE TEN

                                      COVENANTS

         SECTION 1001.  Payment of Principal, Premium, if any, Interest and
Additional Amounts.  The Trust covenants and agrees for the benefit of the
Holders of each series of Securities


                                    -57-


<PAGE>


that it will duly and punctually pay the principal of (and premium, if any) 
and interest on and any Additional Amounts payable in respect of the 
Securities of that series in accordance with the terms of such series of 
Securities, any coupons appertaining thereto and this Indenture.  Unless 
otherwise specified as contemplated by Section 301 with respect to any series 
of Securities, any interest due on and any Additional Amounts payable in 
respect of Bearer Securities on or before Maturity, other than Additional 
Amounts, if any, payable as provided in Section 1010 in respect of principal 
of (or premium, if any, on) such a Security, shall be payable only upon 
presentation and surrender of the several coupons for such interest 
installments as are evidenced thereby as they severally mature.  Unless 
otherwise specified with respect to Securities of any series pursuant to 
Section 301, at the option of the Trust, all payments of principal may be 
paid by check to the registered Holder of the Registered Security or other 
person entitled thereto against surrender of such Security.

         SECTION 1002.  Maintenance of Office or Agency.  If Securities of a
series are issuable only as Registered Securities, the Trust shall maintain in
each Place of Payment for any series of Securities an office or agency where
Securities of that series may be presented or surrendered for 
payment or conversion, where Securities of that series may be surrendered for 
registration of transfer or exchange and where notices and demands to or upon 
the Trust in respect of the Securities of that series and this Indenture may 
be served.  If Securities of a series are issuable as Bearer Securities, the 
Trust will maintain:  (A) in the Borough of Manhattan, New York City, an 
office or agency where any Registered Securities of that series may be 
presented or surrendered for payment or conversion, where any Registered 
Securities of that series may be surrendered for registration of transfer, 
where Securities of that series may be surrendered for exchange, where 
notices and demands to or upon the Trust in respect of the Securities of that 
series and this Indenture may be served and where Bearer Securities of that 
series and related coupons may be presented or surrendered for payment or 
conversion in the circumstances described in the following paragraph (and not 
otherwise); (B) subject to any laws or regulations applicable thereto, in a 
Place of Payment for that series which is located outside the United States, 
an office or agency where Securities of that series and related coupons may 
be presented and surrendered for payment (including payment of any Additional 
Amounts payable on Securities of that series pursuant to Section 1010) or 
conversion; provided, however, that if the Securities of that series are 
listed on the Luxembourg Stock Exchange or any other stock exchange located 
outside the United States and such stock exchange shall so require, the Trust 
will maintain a Paying Agent for the Securities of that series in Luxembourg 
or any other required city located outside the United States, as the case may 
be, so long as the Securities of that series are listed on such exchange; and 
(C) subject to any laws or regulations applicable thereto, in a Place of 
Payment for that series located outside the United States an office or agency 
where any Registered Securities of that series may be surrendered for 
registration of transfer, where Securities of that series may be surrendered 
for exchange and where notices and demands to or upon the Trust in respect of 
the Securities of that series and this Indenture may be served.  The Trust 
will give prompt written notice to the Trustee of the location, and any 
change in the location, of each such office or agency.  If at any time the 
Trust shall fail to maintain any such required 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, except that Bearer Securities of that series and the 
related coupons may be presented and surrendered for

                                       58

<PAGE>

payment (including payment of any Additional Amounts payable on Bearer 
Securities of that series pursuant to Section 1010) or conversion at the 
offices specified in the Security, in London, England, and the Trust hereby 
appoints the same as its agent to receive such respective presentations, 
surrenders, notices and demands, and the Trust hereby appoints the Trustee 
its agent to receive all such presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on or Additional
Amounts in respect of Bearer Securities shall be made at any office or agency of
the Trust in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United
States; provided, however, that, if the Securities of a series are payable in
Dollars, payment of principal of and any premium and interest on any Bearer
Security (including any Additional Amounts payable on Securities of such series
pursuant to Section 1010) shall be made at the office of the designated agent of
the Trust's Paying Agent in the Borough of Manhattan, New York City, if (but
only if) payment in Dollars of the full amount of such principal, premium,
interest or Additional Amounts, as the case may be, at all offices or agencies
outside the United States maintained for the purpose by the Trust in accordance
with this Indenture, is illegal or effectively precluded by exchange controls or
other similar restrictions.

         The Trust may from time to time designate one or more other offices or
agencies where the Securities of one or more series 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 Trust of its obligation to maintain an office or
agency in accordance with the requirements set forth above for Securities of any
series for such purposes.  The Trust will give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location
of any such other office or agency.  Unless otherwise specified with respect to
any Securities pursuant to Section 301 with respect to a series of Securities,
the Trust hereby designates as a Place of Payment for each series of Securities
the office or agency of the Trust in the Borough of Manhattan, New York City,
and initially appoints the Trustee at its Corporate Trust Office as Paying Agent
and as its agent to receive all such presentations, surrenders, notices and
demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Trust
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

         SECTION 1003.  Money for Securities Payments to Be Held in Trust.  If
the Trust shall at any time act as its own Paying Agent with respect to any
series of any Securities and any related coupons, it will, on or before each due
date of the principal of (and premium, if any), or interest on or Additional
Amounts in respect of, any of the Securities of that series, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum in the currency
or currencies,


                                    -59-


<PAGE>


currency unit or units or composite currency or currencies in which the 
Securities of such series are payable (except as otherwise specified pursuant 
to Section 301 for the Securities of such series) sufficient to pay the 
principal (and premium, if any) or interest or Additional Amounts 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 action or 
failure so to act.

         Whenever the Trust shall have one or more Paying Agents for any series
of Securities and any related coupons, it will, before each due date of the
principal of (and premium, if any), or interest on or Additional Amounts in
respect of, any Securities of that series, deposit with a Paying Agent a sum (in
the currency or currencies, currency unit or units or composite currency or
currencies described in the preceding paragraph) sufficient to pay the principal
(and premium, if any) or interest or Additional Amounts, so becoming due, such
sum to be held in trust for the benefit of the Persons entitled to such
principal, premium or interest or Additional Amounts and (unless such Paying
Agent is the Trustee) the Trust will promptly notify the Trustee of its action
or failure so to act.

         The Trust 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

         (1)  hold all sums held by it for the payment of principal of (and
    premium, if any) or interest on Securities or Additional Amounts 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;

         (2)  give the Trustee notice of any default by the Trust (or any other
    obligor upon the Securities) in the making of any such payment of principal
    (and premium, if any) or interest or Additional Amounts; and

         (3)  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.

         The Trust may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Trust Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Trust or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Trust or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

         Except as otherwise provided in the Securities of any series, any
money deposited with the Trustee or any Paying Agent, or then held by the Trust,
in trust for the payment of the principal of (and premium, if any) or interest
on, or any Additional Amounts in respect of, any Security of any series and
remaining unclaimed for two years after such principal (and premium, if


                                    -60-


<PAGE>


any), interest or Additional Amounts has become due and payable shall be paid 
to the Trust upon Trust Request or (if then held by the Trust) shall be 
discharged from such trust; and the Holder of such Security shall thereafter, 
as an unsecured general creditor, look only to the Trust for payment of such 
principal of (and premium, if any) or interest on, or any Additional Amounts 
in respect of, any Security, without interest thereon, and all liability of 
the Trustee or such Paying Agent with respect to such trust money, and all 
liability of the Trust as trustee thereof, shall thereupon cease; provided, 
however, that the Trustee or such Paying Agent, before being required to make 
any such repayment, may at the expense of the Trust cause to be published 
once, in an Authorized Newspaper, notice that such money remains unclaimed 
and that, after a date specified therein, which shall not be less than 30 
days from the date of such publication, any unclaimed balance of such money 
then remaining will be repaid to the Trust.

         SECTION 1004.  Existence.  Subject to Article Eight, the Trust will do
or cause to be done all things necessary to preserve and keep in full force and
effect its existence as a corporation, rights (charter and statutory) and
franchises; provided, however, that the Trust shall not be required to preserve
any right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Trust.

         SECTION 1005.  Maintenance of Properties.  The Trust will cause all of
its material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Trust may be necessary so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times.

         SECTION 1006.  Insurance.  The Trust will, and will cause each of its
Subsidiaries to, keep all of its insurable properties insured against loss or
damage at least equal to their then full insurable value with insurers of
recognized responsibility.

         SECTION 1007.  Payment of Taxes and Other Claims.  The Trust will pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (1) all taxes, assessments and governmental charges levied or
imposed upon it or any Subsidiary or upon the income, profits or property of the
Trust or any Subsidiary, and (2) all lawful claims for labor, materials and
supplies, which, if unpaid, might by law become a material lien upon the
property of the Trust or any Subsidiary; provided, however, that the Trust 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.

         SECTION 1008.  Provision of Financial Information.  Whether or not the
Trust is subject to Section 13 or 15(d) of the Exchange Act, the Trust will
prepare the annual reports, quarterly reports and other documents within 15 days
of each of the respective dates by which the Trust would have been required to
file with the Commission pursuant to such Section 13 or 15(d) and will (i)
transmit by mail to all Holders, as their names and addresses appear in the
Security


                                    -61-


<PAGE>


Register, without cost to such Holders copies of the annual reports, 
quarterly reports and other documents which the Trust would have been 
required to file with the Commission pursuant to Section 13 or 15(d) of the 
Exchange Act if the Trust were subject to such Sections, (ii) file  with the 
Trustee copies of the annual reports, quarterly reports and other documents 
which the Trust would have been required to file with the Commission pursuant 
to Section 13 or 15(d) of the Exchange Act if the Trust were subject to such 
Sections and (iii) promptly upon written request and payment of the 
reasonable cost of duplication and delivery, supply copies of such documents 
to any prospective Holder.

         SECTION 1009.  Statement as to Compliance.  The Trust will deliver to
the Trustee, within 120 days after the end of each fiscal year, a brief
certificate from the principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Trust's
compliance with all conditions and covenants under this Indenture and, in the
event of any noncompliance, specifying such noncompliance and the nature and
status thereof.  For purposes of this Section 1009, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

         SECTION 1010.  Additional Amounts.  If any Securities of a series
provide for the payment of Additional Amounts, the Trust will pay to the Holder
of any Security of such series or any coupon appertaining thereto Additional
Amounts as may be specified as contemplated by Section 301.  Whenever in this
Indenture there is mentioned, in any context except in the case of Section
502(1), the payment of the principal of or any premium or interest on, or in
respect of, any Security of any series or payment of any related coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established pursuant to Section 301
to the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof pursuant to such terms and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding Additional Amounts in those provisions hereof where
such express mention is not made.

         Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate, the Trust will furnish the
Trustee and the Trust's principal Paying Agent or Paying Agents, if other  than
the Trustee, with an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal of and any
premium or interest on the Securities of that series shall be made to Holders of
Securities of that series or any related coupons who are not United States
persons without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of the series.  If any such
withholding shall be required, then such Officers' Certificate shall specify by
country the amount,


                                    -62-


<PAGE>


if any, required to be withheld on such payments to such Holders of 
Securities of that series or related coupons and the Trust will pay to the 
Trustee or such Paying Agent the Additional Amounts required by the terms of 
such Securities.  In the event that the Trustee or any Paying Agent, as the 
case may be, shall not so receive the above-mentioned certificate, then the 
Trustee or such Paying Agent shall be entitled (i) to assume that no such 
withholding or deduction is required with respect to any payment of principal 
or interest with respect to any Securities of a series or related coupons 
until it shall have received a certificate advising otherwise and (ii) to 
make all payments of principal and interest with respect to the Securities of 
a series or related coupons without withholding or deductions until otherwise 
advised.  The Trust covenants to indemnify the Trustee and any Paying Agent 
for, and to hold them harmless against, any loss, liability or expense 
reasonably incurred without negligence or bad faith on their part arising out 
of or in connection with actions taken or omitted by any of them or in 
reliance on any Officers' Certificate furnished pursuant to this Section or 
in reliance on the Trust's not furnishing such an Officers' Certificate.

         SECTION 1011.   Waiver of Certain Covenants.  The Trust may omit in
any particular instance to comply with any term, provision or condition set
forth in Sections 1004 to 1008, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, 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
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Trust and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.


                                    ARTICLE ELEVEN

                               REDEMPTION OF SECURITIES

         SECTION 1101.  Applicability of Article.  Securities of any series
which are redeemable before their Stated Maturity shall be redeemable in
accordance with their terms and (except as otherwise specified as contemplated
by Section 301 for Securities of any series) in accordance with this Article.

         SECTION 1102.  Election to Redeem; Notice to Trustee.  The election of
the Trust to redeem any Securities shall be evidenced by or pursuant to a Board
Resolution.  In case of any redemption at the election of the Trust of less than
all of the Securities of any series, the Trust shall, at least 45 days prior to
the giving of the notice of redemption in Section 1104 (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date and of the principal amount of Securities of such series to be redeemed. 
In the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Trust shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

         SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.  If
less than all the Securities of any series issued on the same day with the same
terms are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series issued on such date with the same
terms not previously called for redemption, by such method as the Trustee shall
deem fair and appropriate and which may provide for the selection for redemption
of portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

         The Trustee shall promptly notify the Trust and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, 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 Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

         SECTION 1104.  Notice of Redemption.  Notice of redemption shall be
given in the manner provided in Section 106, not less than 30 days nor more than
60 days prior to the Redemption Date, unless a shorter period is specified by
the terms of such series established pursuant to Section 301, to each Holder of
Securities to be redeemed, but failure to give such notice in the manner herein
provided to the Holder of any Security designated for redemption as a whole or
in part, or any defect in the notice to any such Holder, shall not affect the
validity of the proceedings for the redemption of any other such Security or
portion thereof.

         Any notice that is mailed to the Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice.

         All notices of redemption shall state:

         (1)  the Redemption Date,

         (2)  the Redemption Price, accrued interest to the Redemption Date
    payable as provided in Section 1106, if any, and Additional Amounts, if
    any,

         (3)  if less than all Outstanding Securities of any series are to be
    redeemed, the identification (and, in the case of partial redemption, the
    principal amount) of the particular Security or Securities to be redeemed,


                                    -64-


<PAGE>


         (4)  in case any Security is to be redeemed in part only, the notice
    which relates to such Security shall state that on and after the Redemption
    Date, upon surrender of such Security, the holder will receive, without a
    charge, a new Security or Securities of authorized denominations for the
    principal amount thereof remaining unredeemed,

         (5)  that on the Redemption Date the Redemption Price and accrued
    interest to the Redemption Date payable as provided in Section 1106, if
    any, will become due and payable upon each such Security, or the portion
    thereof, to be redeemed and, if applicable, that interest thereon shall
    cease to accrue on and after said date,

         (6)  the Place or Places of Payment where such Securities, together in
    the case of Bearer Securities with all coupons appertaining thereto, if
    any, maturing after the Redemption Date, are to be surrendered for payment
    of the Redemption Price and accrued interest, if any, or for conversion,

         (7)  that the redemption is for a sinking fund, if such is the case,

         (8)  that, unless otherwise specified in such notice, Bearer
    Securities of any series, if any, surrendered for redemption must be
    accompanied by all coupons maturing subsequent to the date fixed for
    redemption or the amount of any such missing coupon or coupons will be
    deducted from the Redemption Price, unless security or indemnity
    satisfactory to the Trust, the Trustee for such series and any Paying Agent
    is furnished,

         (9)  if Bearer Securities of any series are to be redeemed and any 
    Registered Securities of such series are not to be redeemed, and if such 
    Bearer Securities may be exchanged for Registered Securities not subject 
    to redemption on this Redemption Date pursuant to Section 305 or 
    otherwise, the last date, as determined by the Trust, on which such 
    exchanges may be made,

         (10) the CUSIP number of such Security, if any, and

         (11) if applicable, that a Holder of Securities who desires to 
    convert Securities for redemption must satisfy the requirements for 
    conversion contained in such Securities, the then existing conversion price
    or rate, and the date and time when the option to convert shall expire.

         Notice of redemption of Securities to be redeemed shall be given by
the Trust or, at the Trust's request, by the Trustee in the name and at the
expense of the Trust.

         SECTION 1105.  Deposit of Redemption Price.  At least one Business Day
prior to any Redemption Date, the Trust shall deposit with the Trustee or with a
Paying Agent (or, if the Trust is acting as its own Paying Agent, which it may
not do in the case of a sinking fund payment under Article Twelve, segregate and
hold in trust as provided in Section 1003) an amount of money


                                    -65-


<PAGE>


in the currency or currencies, currency unit or units or composite currency 
or currencies in which the Securities of such series are payable (except as 
otherwise specified pursuant to Section 301 for the Securities of such 
series) sufficient to pay on the Redemption Date the Redemption Price of, and 
(except if the Redemption Date shall be an Interest Payment Date) accrued 
interest on, all the Securities or portions thereof which are to be redeemed 
on that date.

         SECTION 1106.  Securities Payable on Redemption Date.  Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Trust shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons
for such interest appertaining to any Bearer Securities so to be redeemed,
except to the extent provided below, shall be void.  Upon surrender of any such
Security for redemption in accordance with said notice, together with all
coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Trust at the Redemption Price, together with
accrued interest, if any, to the Redemption Date; provided, however, that
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
that, except as otherwise provided with respect to Securities convertible into
Common Stock or Preferred Stock, installments of interest on Registered
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Trust and the Trustee if there be
furnished to them such security or indemnity as they may require to save each of
them and any Paying Agent harmless.  If thereafter the Holder of such Security
shall surrender to the Trustee or any Paying Agent any such missing coupon in
respect of which a deduction shall have been made from the Redemption Price,
such Holder shall be entitled to receive the amount so deducted; provided,
however, that interest represented by coupons shall be payable only at an office
or agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified as contemplated by Section 301,
only upon presentation and surrender of those coupons.


                                    -66-


<PAGE>


         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Security.

         SECTION 1107.  Securities Redeemed in Part.  Any Registered Security
which is to be redeemed only in part (pursuant to the provisions of this Article
or of Article Twelve) shall be surrendered at a Place of Payment therefor (with,
if the Trust or the Trustee so requires, due endorsement by, or a written
instrument of transfer in form satisfactory to the Trust and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing) and
the Trust shall execute and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge a new Security or Securities of
the same series, 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 Security so surrendered.


                                    ARTICLE TWELVE

                                    SINKING FUNDS

         SECTION 1201.  Applicability of Article.  The provisions of this
Article shall be applicable to any sinking fund for the retirement of Securities
of a series except as otherwise specified as contemplated by Section 301 for
Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment", and any payment in excess of such minimum amount provided for by
the terms of such Securities of any series is herein referred to as an "optional
sinking fund payment".  If provided for by the terms of any Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to
reduction as provided in Section 1202.  Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

         SECTION 1202.  Satisfaction of Sinking Fund Payments with Securities. 
The Trust may, in satisfaction of all or any part of any mandatory sinking fund
payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Trust pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Trust; provided that such Securities so delivered or applied as a credit have
not been previously so credited.  Such Securities shall be received and credited
for such purpose by the Trustee at the applicable Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such mandatory sinking fund payment shall be reduced accordingly.


                                    -67-


<PAGE>


         SECTION 1203.  Redemption of Securities for Sinking Fund.  Not less
than 60 days prior to each sinking fund payment date for Securities of any
series, the Trust will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing mandatory sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202, and the optional amount, if any, to be added in cash
to the next ensuing mandatory sinking fund payment, and will also deliver to the
Trustee any Securities to be so delivered and credited.  If such Officers'
Certificate shall specify an optional amount to be added in cash to the next
ensuing mandatory sinking fund payment, the Trust shall thereupon be obligated
to pay the amount therein specified.  Not less than 30 days before each such
sinking fund payment date the Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 1103 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Trust in the manner provided in Section 1104.  Such notice having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 1106 and 1107.


                                   ARTICLE THIRTEEN

                          REPAYMENT AT THE OPTION OF HOLDERS

         SECTION 1301.  Applicability of Article.  Repayment of Securities of
any series before their Stated Maturity at the option of Holders thereof shall
be made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.

         SECTION 1302.  Repayment of Securities.  Securities of any series
subject to repayment in whole or in part at the option of the Holders thereof
will, unless otherwise provided in the terms of such Securities, be repaid at a
price equal to the principal amount thereof, together with interest, if any,
thereon accrued to the Repayment Date specified in or pursuant to the terms of
such Securities.  The Trust covenants that at least one Business Day prior to
the Repayment Date it will deposit with the Trustee or with a Paying Agent (or,
if the Trust is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay the principal
(or, if so provided by the terms of the Securities of any series, a percentage
of the principal) of, and (except if the Repayment Date shall be an Interest
Payment Date) accrued interest on, all the Securities or portions thereof, as
the case may be, to be repaid on such date.


                                    -68-

<PAGE>

         SECTION 1303.  Exercise of Option.  Securities of any series subject
to repayment at the option of the Holders thereof will contain an "Option to
Elect Repayment" form on the reverse of such Securities.  In order for any
Security to be repaid at the option of the Holder, the Trustee must receive at
the Place of Payment therefor specified in the terms of such Security (or at
such other place or places of which the Trust shall from time to time notify the
Holders of such Securities) not earlier than 60 days nor later than 30 days
prior to the Repayment Date (1) the Security so providing for such repayment
together with the "Option to Elect Repayment" form on the reverse thereof duly
completed by the Holder (or by the Holder's attorney duly authorized in writing)
or (2) a telegram, telex, facsimile transmission or a letter from a member of a
national securities exchange, or the National Association of Securities Dealers,
Inc. ("NASD"), or a commercial bank or trust company in the United States
setting forth the name of the Holder of the Security, the principal amount of
the Security, the principal amount of the Security to be repaid, the CUSIP
number, if any, or a description of the tenor and terms of the Security, a
statement that the option to elect repayment is being exercised thereby and a
guarantee that the Security to be repaid, together with the duly completed form
entitled "Option to Elect Repayment" on the reverse of the Security, will be
received by the Trustee not later than the fifth Business Day after the date of
such telegram, telex, facsimile transmission or letter; provided, however, that
such telegram, telex, facsimile transmission or letter shall only be effective
if such Security and form duly completed are received by the Trustee by such
fifth Business Day.  If less than the entire principal amount of such Security
is to be repaid in accordance with the terms of such Security, the principal
amount of such Security to be repaid, in increments of the minimum denomination
for Securities of such series, and the denomination or denominations of the
Security or Securities to be issued to the Holder for the portion of the
principal amount of such Security surrendered that is not to be repaid, must be
specified.  The principal amount of any Security providing for repayment at the
option of the Holder thereof may not be repaid in part if, following such
repayment, the unpaid principal amount of such Security would be less than the
minimum authorized denomination of Securities of the series of which such
Security to be repaid is a part.  Except as otherwise may be provided by the
terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Trust.

         SECTION 1304.  When Securities Presented for Repayment Become Due and
Payable.  If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Trust on the Repayment Date therein specified,
and on and after such Repayment Date (unless the Trust shall default in the
payment of such Securities on such Repayment Date) such Securities shall, if the
same were interest-bearing, cease to bear interest and the coupons for such
interest appertaining to any Bearer Securities so to be repaid, except to the
extent provided below, shall be void.  Upon surrender of any such Security for
repayment in accordance with such provisions, together with all coupons, if any,
appertaining thereto maturing after the Repayment Date, the principal amount of
such Security so to be repaid shall be paid by the Trust, together with accrued
interest, if any, to the Repayment Date; provided, however, that coupons whose
Stated Maturity is on or prior to the Repayment Date shall be payable only at an
office or 

                                      -69-

<PAGE>

agency located outside the United States (except as otherwise provided
in Section 1002) and, unless otherwise specified pursuant to Section 301, only
upon presentation and surrender of such coupons; and provided further that, in
the case of Registered Securities, installments of interest, if any, whose
Stated Maturity is on or prior to the Repayment Date shall be payable (but
without interest thereon, unless the Trust shall default in the payment thereof)
to the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 307.

         If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Trust and the Trustee if there be furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Security shall surrender to the Trustee or any
Paying Agent any such missing coupon in respect of which a deduction shall have
been made as provided in the preceding sentence, such Holder shall be entitled
to receive the amount so deducted; provided, however, that interest represented
by coupons shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified as contemplated by Section 301, only upon presentation and
surrender of those coupons.

         If the principal amount of any Security surrendered for repayment
shall not be so repaid upon surrender thereof, such principal amount (together
with interest, if any, thereon accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

         SECTION 1305.  Securities Repaid in Part.  Upon surrender of any
Registered Security which is to be repaid in part only, the Trust shall execute
and the Trustee shall authenticate and deliver to the Holder of such Security,
without service charge and at the expense of the Trust, a new Registered
Security or Securities of the same series, of any authorized denomination
specified by the Holder, in an aggregate principal amount equal to and in
exchange for the portion of the principal of such Security so surrendered which
is not to be repaid.


                                   ARTICLE FOURTEEN

                          DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401.  Applicability of Article; Trust's Option to Effect
Defeasance or Covenant Defeasance.  If, pursuant to Section 301, provision is
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or

                                      -70-

<PAGE>

Sections, as the case may be, together with the other provisions of this 
Article (with such modifications thereto as may be specified pursuant to 
Section 301 with respect to any Securities), shall be applicable to such 
Securities and any coupons appertaining thereto, and the Trust may at its 
option by Board Resolution, at any time, with respect to such Securities and 
any coupons appertaining thereto, elect to have Section 1402 (if applicable) 
or Section 1403 (if applicable) be applied to such Outstanding Securities and 
any coupons appertaining thereto upon compliance with the conditions set 
forth below in this Article.

         SECTION 1402.  Defeasance and Discharge.  Upon the Trust's exercise 
of the above option applicable to this Section with respect to any Securities 
of or within a series, the Trust shall be deemed to have been discharged from 
its obligations with respect to such Outstanding Securities and any coupons 
appertaining thereto on the date the conditions set forth in Section 1404 are 
satisfied (hereinafter, "defeasance").  For this purpose, such defeasance 
means that the Trust shall be deemed to have paid and discharged the entire 
indebtedness represented by such Outstanding Securities and any coupons 
appertaining thereto, which shall thereafter be deemed to be "Outstanding" 
only for the purposes of Section 1405 and the other Sections of this 
Indenture referred to in clauses (A) and (B) below, and to have satisfied all 
of its other obligations under such Securities and any coupons appertaining 
thereto and this Indenture insofar as such Securities and any coupons 
appertaining thereto are concerned (and the Trustee, at the expense of the 
Trust, shall execute proper instruments acknowledging the same), except for 
the following which shall survive until otherwise terminated or discharged 
hereunder:  (A) the rights of Holders of such Outstanding Securities and any 
coupons appertaining thereto to receive, solely from the trust fund described 
in Section 1404 and as more fully set forth in such Section, payments in 
respect of the principal of (and premium, if any) and interest, if any, on 
such Securities and any coupons appertaining thereto when such payments are 
due, (B) the Trust's obligations with respect to such Securities under 
Sections 305, 306, 1002 and 1003 and with respect to the payment of 
Additional Amounts, if any, on such Securities as contemplated by Section 
1010, (C) the rights, powers, trusts, duties and immunities of the Trustee 
hereunder and (D) this Article.  Subject to compliance with this Article 
Fourteen, the Trust may exercise its option under this Section 
notwithstanding the prior exercise of its option under Section 1403 with 
respect to such Securities and any coupons appertaining thereto.

         SECTION 1403.  Covenant Defeasance.  Upon the Trust's exercise of 
the above option applicable to this Section with respect to any Securities of 
or within a series, the Trust shall be released from its obligations under 
Sections 1004 to 1008, inclusive, and, if specified pursuant to Section 301, 
its obligations under any other covenant, with respect to such Outstanding 
Securities and any coupons appertaining thereto on and after the date the 
conditions set forth in Section 1404 are satisfied (hereinafter, "covenant 
defeasance"), and such Securities and any coupons appertaining thereto shall 
thereafter be deemed to be not "Outstanding" for the purposes of any 
direction, waiver, consent or declaration or Act of Holders (and the 
consequences of any thereof) in connection with Sections 1004 to 1008, 
inclusive, or such other covenant, but shall continue to be deemed 
"Outstanding" for all other purposes hereunder.  For this purpose, such 
covenant defeasance means that, with respect to such Outstanding Securities 
and any coupons appertaining thereto, the Trust may omit to comply with and 
shall have no liability in respect of any term, condition or limitation 

                                      -71-

<PAGE>

set forth in any such Section or such other covenant, whether directly or 
indirectly, by reason of any reference elsewhere herein to any such Section 
or such other covenant or by reason of reference in any such Section or such 
other covenant to any other provision herein or in any other document and 
such omission to comply shall not constitute a default or an Event of Default 
under Section 501(4) or 501(8) or otherwise, as the case may be, but, except 
as specified above, the remainder of this Indenture and such Securities and 
any coupons appertaining thereto shall be unaffected thereby.

         SECTION 1404.  Conditions to Defeasance or Covenant Defeasance.  The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

         (a)   The Trust shall irrevocably have deposited or caused to be
    deposited with the Trustee (or another trustee satisfying the requirements
    of Section 607 who shall agree to comply with the provisions of this
    Article Fourteen applicable to it) as trust funds in trust for the purpose
    of making the following payments, specifically pledged as security for, and
    dedicated solely to, the benefit of the Holders of such Securities and any
    coupons appertaining thereto, (1) an amount in such currency, currencies or
    currency unit in which such Securities and any coupons appertaining thereto
    are then specified as payable at Stated Maturity, or (2) Government
    Obligations applicable to such Securities and coupons appertaining thereto
    (determined on the basis of the currency, currencies or currency unit in
    which such Securities and coupons appertaining thereto are then specified
    as payable at Stated Maturity) which through the scheduled payment of
    principal and interest in respect thereof in accordance with their terms
    will provide, not later than one day before the due date of any payment of
    principal of (and premium, if any) and interest, if any, on such Securities
    and any coupons appertaining thereto, money in an amount, or (3) a
    combination thereof, in any case, in an amount, sufficient, without
    consideration of any reinvestment of such principal and interest, in the
    opinion of a nationally recognized firm of independent public accountants
    expressed in a written certification thereof delivered to the Trustee, to
    pay and discharge, and which shall be applied by the Trustee (or other
    qualifying trustee) to pay and discharge, (i) the principal of (and
    premium, if any) and interest, if any, on such Outstanding Securities and
    any coupons appertaining thereto on the Stated Maturity of such principal
    or installment of principal or interest and (ii) any mandatory sinking fund
    payments or analogous payments applicable to such Outstanding Securities
    and any coupons appertaining thereto on the day on which such payments are
    due and payable in accordance with the terms of this Indenture and of such
    Securities and any coupons appertaining thereto.

         (b)  Such defeasance or covenant defeasance shall not result in a
    breach or violation of, or constitute a default under, this Indenture or
    any other material agreement or instrument to which the Trust is a party or
    by which it is bound.

         (c)  No Event of Default or event which with notice or lapse of time
    or both would become an Event of Default with respect to such Securities
    and any coupons appertaining thereto shall have occurred and be continuing
    on the date of such deposit or, insofar as

    Sections 501(6) and 501(7) are concerned, at any time during the period 
    ending on the 91st day after the date of such deposit (it being understood
    that this condition shall not be deemed satisfied until the expiration of 
    such period).

         (d)  In the case of an election under Section 1402, the Trust shall
    have delivered to the Trustee an Opinion of Counsel stating that (i) the
    Trust has received from, or there has been published by, the Internal
    Revenue Service a ruling, or (ii) since the date of execution of this
    Indenture, there has been a change in the applicable Federal income tax
    law, in either case to the effect that, and based thereon such opinion
    shall confirm that, the Holders of such Outstanding Securities and any
    coupons appertaining thereto will not recognize income, gain or loss for
    Federal income tax purposes as a result of such defeasance and will be
    subject to Federal income tax on the same amounts, in the same manner and
    at the same times as would have been the case if such defeasance had not
    occurred.

         (e)  In the case of an election under Section 1403, the Trust shall
    have delivered to the Trustee an Opinion of Counsel to the effect that the
    Holders of such Outstanding Securities and any coupons appertaining thereto
    will not recognize income, gain or loss for Federal income tax purposes as
    a result of such covenant defeasance and will be subject to Federal income
    tax on the same amounts, in the same manner and at the same times as would
    have been the case if such covenant defeasance had not occurred.

         (f)  The Trust shall have delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel, each stating that all conditions
    precedent to the defeasance under Section 1402 or the covenant defeasance
    under Section 1403 (as the case may be) have been complied with and an
    Opinion of Counsel to the effect that either (i) as a result of a deposit
    pursuant to subsection (a) above and the related exercise of the Trust's
    option under Section 1402 or Section 1403 (as the case may be),
    registration is not required under the Investment Trust Act of 1940, as
    amended, by the Trust, with respect to the trust funds representing such
    deposit or by the Trustee for such trust funds or (ii) all necessary
    registrations under said Act have been effected.

         (g)  Notwithstanding any other provisions of this Section, such
    defeasance or covenant defeasance shall be effected in compliance with any
    additional or substitute terms, conditions or limitations which may be
    imposed on the Trust in connection therewith pursuant to Section 301.

         SECTION 1405.  Deposited Money and Government Obligations to Be Held
in Trust; Other Miscellaneous Provisions.  Subject to the provisions of the last
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons appertaining
thereto shall be held in trust and applied by the Trustee, in accordance with
the provisions of such Securities and any coupons 

                                     -73-

appertaining thereto and this Indenture, to the payment, either directly or 
through any Paying Agent (including the Trust acting as its own Paying Agent) 
as the Trustee may determine, to the Holders of such Securities and any 
coupons appertaining thereto of all sums due and to become due thereon in 
respect of principal (and premium, if any) and interest and Additional 
Amounts, if any, but such money need not be segregated from other funds 
except to the extent required by law.

         Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium, if any), and
interest, if any, on such Security as the same becomes due out of the proceeds
yielded by converting (from time to time as specified below in the case of any
such election) the amount or other property deposited in respect of such
Security into the currency or currency unit in which such Security becomes
payable as a result of such election or Conversion Event based on the applicable
market exchange rate for such currency or currency unit in effect on the second
Business Day prior to each payment date, except, with respect to a Conversion
Event, for such currency or currency unit in effect (as nearly as feasible) at
the time of the Conversion Event.

         The Trust shall pay and indemnify the Trustee against any tax, fee 
or other charge imposed on or assessed against the Government Obligations 
deposited pursuant to Section 1404 or the principal and interest received in 
respect thereof other than any such tax, fee or other charge which by law is 
for the account of the Holders of such Outstanding Securities and any coupons 
appertaining thereto.

         Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Trust from time to time
upon Trust Request any money or Government Obligations (or other property and
any proceeds therefrom) held by it as provided in Section 1404 which, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Article.

of Holders of Securities of any series may be called at any time and from time
to time pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such
series.

         SECTION 1502.  Call, Notice and Place of Meetings.  (a)  The Trustee
may at any time call a meeting of Holders of Securities of any series for any
purpose specified in Section 1501, to be held at such time and at such place in
the Borough of Manhattan, New York City, or in London as the Trustee shall
determine.  Notice of every meeting of Holders of Securities of any series,
setting forth the time and the place of such meeting and in general terms the
action proposed to be taken at such meeting, shall be given, in the manner
provided in Section 106, not less than 21 nor more than 180 days prior to the
date fixed for the meeting.

         (b)  In case at any time the Trust, pursuant to a Board Resolution, or
the Holders of at least 10% in principal amount of the Outstanding Securities of
any series shall have requested the Trustee to call a meeting of the Holders of
Securities of such series for any purpose specified in Section 1501, by written
request setting forth in reasonable detail the action proposed to be taken at
the meeting, and the Trustee shall not have made the first publication of the
notice of such meeting within 21 days after receipt of such request or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Trust or the Holders of Securities of such series in the amount above specified,
as the case may be, may determine the time and the place in the Borough of
Manhattan, New York City, or in London for such meeting and may call such
meeting for such purposes by giving notice thereof as provided in subsection (a)

         SECTION 1503.  Persons Entitled to Vote at Meetings.  To be entitled
to vote at any meeting of Holders of Securities of any series, a Person shall be
(1) a Holder of one or more Outstanding Securities of such series, or (2) a
Person appointed by an instrument in writing as proxy for a Holder or Holders of
one or more Outstanding Securities of such series by such Holder or Holders. 
The only Persons who shall be entitled to be present or to speak at any meeting

of

                                     -75-

<PAGE>

the Outstanding Securities of a series, the Persons entitled to vote such
specified percentage in principal amount of the Outstanding Securities of such
series shall constitute a quorum.  In the absence of a quorum within 30 minutes
after the time appointed for any such meeting, the meeting shall, if convened at
the request of Holders of Securities of such series, be dissolved.  In any other
case the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting.  In the absence of a quorum at the reconvening of any such adjourned
meeting, such adjourned meeting may be further adjourned for a period of not
less than 10 days; at the reconvening of any meeting adjourned or further
adjourned for lack of a quorum, the persons entitled to vote 25% in the
aggregate principal amount of the Securities at the time outstanding shall
constitute a quorum for the taking of any action set forth in the notice of the
original meeting.  Notice of the reconvening of any adjourned meeting shall be
given as provided in Section 1502(a), except that such notice need be given only
once not less than five days prior to the date on which the meeting is scheduled
to be reconvened.

         Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted by the affirmative vote of the persons
entitled to vote a majority in aggregate principal amount of the Outstanding
Securities represented at such meeting; provided, however, that, except as
limited by the proviso to Section 902, any resolution with respect to any
request, demand, authorization, direction, notice, consent, waiver or other
action which this Indenture expressly provides may be made, given or taken by
the Holders of a specified percentage, which is less than a majority, in
principal amount of the Outstanding Securities of a series may be adopted at a
meeting or an adjourned meeting duly reconvened and at which a quorum is present
as aforesaid by the affirmative vote of the Holders of such specified percentage
in principal amount of the Outstanding Securities of that series.

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

         Notwithstanding the foregoing provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given

    such series that vote in favor of such request, demand, authorization,
    direction, notice, consent, waiver or other action shall be taken into
    account in determining whether such request, demand, authorization,
    direction, notice, consent, waiver or other action has been made, given or
    taken under this Indenture.

         SECTION 1505.  Determination of Voting Rights; Conduct and Adjournment
of Meetings.  (a)  Notwithstanding any provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate. 
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities.  Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

         (b)  The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Trust or by Holders of Securities as provided in Section 1502(b), in which
case the Trust or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman.  A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (c)  At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding.  The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

         (d)  Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

         SECTION 1506.  Counting Votes and Recording Action of Meetings.  The
vote upon any resolution submitted to any meeting of Holders of Securities of
any series shall be by written ballots on which shall be subscribed the
signatures of the Holders of Securities of such series or of their
representatives by proxy and the principal amounts and serial numbers of the
Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in duplicate of all votes cast at the meeting.  A record, at least in
duplicate, of the proceedings of each meeting of Holders of Securities of any
Series shall be prepared by the secretary of the meeting

                                     -77-

<PAGE>

and there shall be attached to said record the original reports of the 
inspectors of votes on any vote by ballot taken thereat and affidavits by one 
or more persons having knowledge of the fact, setting forth a copy of the 
notice of the meeting and showing that said notice was given as provided in 
Section 1502 and, if applicable, Section 1504.  Each copy shall be signed and 
verified by the affidavits of the permanent chairman and secretary of the 
meeting and one such copy shall be delivered to the Trust and another to the 
Trustee to be preserved by the Trustee, the latter to have attached thereto 
the ballots voted at the meeting.  Any record so signed and verified shall be 
conclusive evidence of the matters therein stated.

                                   ARTICLE SIXTEEN

                                    SUBORDINATION

         SECTION 1601.  Agreement to Subordinate.  The Trust agrees, and each
Holder by accepting a Security agrees, that the indebtedness evidenced by the
Securities is subordinated in right of payment, to the extent and in the manner
provided in this Article, to the prior payment in full of all Senior Debt and
that the subordination is for the benefit of the holders of Senior Debt.

         SECTION 1602.  Liquidation; Dissolution; Bankruptcy.  Upon any
distribution to creditors of the Trust in a liquidation or dissolution of the
Trust or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Trust or its property:

              (1)  holders of Senior Debt shall be entitled to receive payment
         in full in cash of the principal of and interest (including interest
         accruing after the commencement of any such proceeding) to the date of
         payment on the Senior Debt before Holders shall be entitled to receive
         any payment of principal of or interest on Securities;

              (2)  until the Senior Debt is paid in full in cash, any
         distribution in which Holders would be entitled but for this Article
         shall be made to holders of Senior Debt as their interests may appear,
         except that Holders may receive securities that are subordinated to
         Senior Debt to at least the same extent as the Securities; and

              (3)  the Trustee is entitled to rely upon an order or decree of a
         court of competent jurisdiction or a certificate of a bankruptcy
         trustee or other similar official for the purpose of ascertaining the
         persons entitled to participate in such distribution, the holders of
         Senior Debt and other Trust debt, the amount thereof or payable
         thereon and all other pertinent facts relating to the Trustee's
         obligations under this Article Sixteen.

                                      -78-

<PAGE>

         SECTION 1603.  Default on Senior Debt.  The Trust may not pay
principal of or interest on the Securities and may not acquire any Securities
for cash or property other than Capital Stock of the Trust if:

              (1)  a default on Senior Debt occurs and is continuing that
         permits holders of such Senior Debt to accelerate its maturity, and

              (2)  the default is the subject of judicial proceedings or the
         Trust receives a notice of the default from a person who may give it
         pursuant to Section 1611.  If the Trust receives any such notice, a
         similar notice received within nine months thereafter relating to the
         same default on the same issue of Senior Debt shall not be effective
         for purposes of this Section.

         The Trust may resume payments on the Securities and may acquire them
when:

              (a)  the default is cured or waived, or

              (b)  120 days pass after the notice is given if the default is
         not the subject of judicial proceedings.

if this Article otherwise permits the payment or acquisition at that time.

         SECTION 1604.  Acceleration of Securities.  If payment of the
Securities is accelerated because of an Event of Default, the Trust shall
promptly notify holders of Senior Debt of the acceleration.  The Trust may pay
the Securities when 120 days pass after the acceleration occurs if this Article
permits the payment at that time.

         SECTION 1605.  When Distribution Must Be Paid Over.  If a distribution
is made to Holders that because of this Article should not have been made to
them, the Holders who receive the distribution shall hold it in trust for
holders of Senior Debt and pay it over to them as their interests may appear.

         SECTION 1606.  Notice by Trust.  The Trust shall promptly notify the
Trustee and any Paying Agent of any facts known to the Trust that would cause a
payment of principal of or interest on the Securities to violate this Article.

         SECTION 1607.  Subrogation.  After all Senior Debt is paid in full and
until the Securities are paid in full, Holders shall be subrogated to the rights
of holders of Senior Debt to receive distributions applicable to Senior Debt to
the extent that distributions otherwise payable to the Holders have been applied
to the payment of Senior Debt.  A distribution made under this Article to
holders of Senior Debt which otherwise would have been made to Holders is not,
as between the Trust and Holders, a payment by the Trust on Senior Debt.

                                     -79-

<PAGE>

         SECTION 1608.  Relative Rights.  This Article defines the relative
rights of Holders and holders of Senior Debt.  Nothing in this Indenture shall:

              (1)  impair, as between the Trust and Holders, the obligation of
         the Trust, which is absolute and unconditional, to pay principal of
         and interest on the Securities in acceptance with their terms;

              (2)  affect the relative rights of Holders and creditors of the
         Trust other than holders of Senior Debt; or

              (3)  prevent the Trustee or any Holder from exercising its
         available remedies upon an Event of Default, subject to the rights of
         holders of Senior Debt to receive distributions otherwise payable to
         Holders.

         If the Trust fails because of this Article to pay principal of or
interest on a Security on the due date, the failure is still a default.

         SECTION 1609.  Subordination May Not Be Impaired by Trust.  No right
of any holder of Senior Debt to enforce the subordination of the indebtedness
evidenced by the Securities shall be impaired by any act or failure to act by
the Trust or by its failure to comply with this Indenture.

         SECTION 1610.  Distribution or Notice to Representative.  Whenever a
distribution is to be made or a notice given to holders of Senior Debt, the
distribution may be made and the notice given to their Representative.

         SECTION 1611.  Rights of Trustee and Paying Agent.  The Trustee or any
Paying Agent may continue to make payments on the Securities until it receives
written notice of facts that would cause a payment of principal of or interest
on the Securities to violate this Article.  Only the Trust, a Representative or
a holder of an issue of Senior Debt that has no Representative may give the
written notice.

         The Trustee has no fiduciary duty to the holders of Senior Debt other
than as created under this Indenture.  The Trustee in its individual or any
other capacity may hold Senior Debt with the same rights it would have if it
were not Trustee.

         The Trust's obligation to pay, and the Trust's payment of, the
Trustee's fees pursuant to Section 606 are excluded from the operation of this
Article Sixteen.

Washington Real Estate Investment Trust
10400 Connecticut Avenue, N.W.
Concourse Level
Kensington, MD  20895

Gentlemen:

    We have acted as counsel to Washington Real Estate Investment Trust, a 
real estate investment trust organized under the laws of Maryland (the 
"Trust"), in connection with the Form S-3 registration statement (the 
"Registration Statement") being filed by the Trust with the Securities and 
Exchange Commission under the Securities Act of 1933, as amended (the "Act"), 
relating to the offering from time to time, as set forth in the prospectus 
contained in such Registration Statement (the "Prospectus") and as to be set 
forth in one or more supplements to the Prospectus (each, a "Prospectus 
Supplement"), of up to $200,000,000 aggregate offering price of (i) one or 
more series of the Trust's debt securities ("Debt Securities"), (ii) one or 
more series of the Trust's preferred shares of beneficial interest 
("Preferred Shares"), (iii) the Trust's common shares of beneficial interest 
("Common Shares")  and/or (iv) warrants to purchase Common Shares 
("Warrants").

    The senior Debt Securities ("Senior Debt Securities") will be issued 
pursuant to an Indenture dated August 1, 1996 (the "Senior Indenture") 
between the Trust and The First National Bank of Chicago (the "Senior 
Trustee"), and the subordinated Debt Securities ("Subordinated Debt 
Securities") will be issued pursuant to a form of Indenture (the 
"Subordinated Indenture") between the Trust and a commercial bank to be 
identified (the "Subordinated Trustee").  The Preferred Shares will be issued 
pursuant to an amendment to the Trust's Declaration of Trust (the 
"Declaration of Trust") and one or more certificates of designation filed 
pursuant to the Declaration of Trust.  The Warrants will be issued pursuant 
to one or more forms of Warrant Agreement (the "Warrant Agreement") between 
the Trust and a commercial bank to be identified (the "Warrant Agent").

    We have examined and relied upon the originals or copies of such records, 
agreements, documents and other instruments and have made such inquiries of 
such officers and representatives of the Trust as we have deemed relevant and 
necessary as the basis for the opinions set forth.  In such examination, we 
have assumed, without independent verification, the genuineness of all 
signatures (whether original or photostatic), the legal capacity of natural 
persons, the authenticity of all documents submitted to us as originals, and 
the conformity to original documents of all documents submitted to us as 
certified or photostatic copies.  We have assumed, without independent 
verification, the accuracy of the relevant facts stated therein.

    Based upon the foregoing and subject to the qualifications set forth 
below, we are of the opinion that:

    1.   The Senior Indenture and the Subordinated Indenture have been duly 
authorized by the Trust.  The Senior Indenture is, and the Subordinated 
Indenture when duly executed and delivered by the Trust will be, the legally 
valid and binding agreement of the Trust.

    2.   When the Senior Debt Securities have been duly established pursuant 
to the Senior Indenture, duly authenticated by the Senior Trustee and duly 
executed and delivered on behalf of the Trust against payment therefor in 
accordance with the terms and provisions of the Senior Indenture and as 
contemplated by the

Page 2


Registration Statement and/or the applicable Prospectus Supplement, the 
Senior Debt Securities will be validly issued and constitute binding 
obligations of the Trust.

    3.   When the Subordinated Debt Securities have been duly established 
pursuant to the Subordinated Indenture, duly authenticated by the 
Subordinated Trustee and duly executed and delivered on behalf of the Trust 
against payment therefor in accordance with the terms and provisions of the 
Subordinated Indenture and as contemplated by the Registration Statement 
and/or the applicable Prospectus Supplement, the Subordinated Debt Securities 
will be validly issued and constitute binding obligations of the Trust.

    4.   When the Trust's Board of Trustees has approved an amendment to the 
Declaration of Trust authorizing the issuance of Preferred Shares (the 
"Preferred Share Amendment"), the Preferred Share Amendment has been duly 
approved by the Trust's shareholders, the Preferred Shares have been duly 
established pursuant to the Declaration of Trust and the applicable 
certificate of designation and the Preferred Shares have been issued and 
delivered on behalf of the Trust against payment therefor  as contemplated by 
the Registration Statement and/or the applicable Prospectus Supplement, the 
Preferred Shares will be validly issued, fully paid and nonassessable.

    5.   The Common Shares to be sold by the Trust, when issued and delivered 
on behalf of the Trust against payment therefor as contemplated by the 
Registration Statement and/or the applicable Prospectus Supplement, will be 
validly issued, fully paid and nonassessable.

    6.   When the Trust's Board of Trustees has approved the Warrant 
Agreement, the Warrants have been duly established pursuant to the Warrant 
Agreement and the Warrants have been issued and delivered on behalf of the 
Trust against payment therefor as contemplated by the Registration Statement 
and/or the applicable Prospectus Supplement, the Warrants will be validly 
issued and constitute binding obligations of the Trust.

    7.   Based upon our review of the Declaration of Trust, the actual 
operations of the Trust to date and the proposed continuing method of 
operation of the Trust, as set forth, or incorporated by reference, in the 
Prospectus and assuming that the Trust will continue to operate in the manner 
in which it has to date, according to the policies and in the manner stated 
in the Declaration of Trust and as set forth, or incorporated by reference, 
in the Prospectus, the Trust will continue to qualify as a Real Estate 
Investment Trust pursuant to the Internal Revenue Code of 1986, and under 
present law the federal income tax treatment of the Trust will be as set 
forth in the Prospectus under the heading "Description of Shares -- Taxation."

    To the extent that the obligations of the Trust under the Senior 
Indenture or Subordinated Indenture may be dependent upon such matters, we 
assume for purposes of this opinion that the Senior Trustee or the 
Subordinated Trustee, as appropriate, will be duly organized, validly 
existing and in good standing under the laws of the jurisdiction of 
organization of such Trustee; that such Trustee will be in compliance 
generally with respect to acting as a trustee under the applicable Indenture 
and with all applicable laws and regulations; and that such Trustee will have 
the requisite organizational and legal power and authority to perform its 
respective obligations under such applicable Indenture.

    To the extent that the obligations of the Trust under the Warrant 
Agreement may be dependent upon such matters, we assume for purposes of this 
opinion that the Warrant Agent will be duly organized, validly existing and 
in good standing under the laws of the jurisdiction of organization of such 
Agent; that such Agent will be in compliance generally with respect to acting 
as an agent under the Warrant Agreement and with all applicable laws and 
regulations; and that such Agent will have the requisite organizational and 
legal power and authority to perform its obligations under such Warrant 
Agreement.
