The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for forward-looking statements. Certain information included in
this Quarterly Report on Form 10-Q contain statements that are or will be
forward-looking, such as statements relating to acquisitions,
dispositions and other business development and development activities,
future capital expenditures, the costs and risks associated with the Year
2000 issue, financing sources and availability, and the effects of
regulation (including environmental regulation) and competition. Such
forward-looking information involves important risks and uncertainties
that could significantly affect anticipated results in the future and,
accordingly, such results may differ from those expressed in any
forward-looking statements made by, or on behalf of, Liberty Property
Trust and Liberty Property Limited Partnership (together, the "Company").
These risks and uncertainties include, but are not limited to,
uncertainties affecting real estate businesses generally (such as entry
into new leases, renewals of leases and dependence on tenants' business
operations), risks relating to acquisition, construction and development
activities, possible environmental liabilities, risks relating to
leverage and debt service (including availability of financing terms
acceptable to the Company and sensitivity of the Company's operations to
fluctuations in interest rates), the potential for the use of borrowings
to make distributions necessary to qualify as a REIT, dependence on the
primary markets in which the Company's properties are located, the
existence of complex regulations relating to status as a REIT and the
adverse consequences of the failure to qualify as a REIT, the potential
adverse impact of market interest rates on the market price for the
Company's securities and risks relating to the Year 2000 issue.

NOTE 2 - ORGANIZATION
- ---------------------

Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT").  Substantially
all of the Trust's assets are owned directly or indirectly, and
substantially all of the Trust's operations are conducted directly or
indirectly, by its subsidiary, Liberty Property Limited Partnership, a
Pennsylvania limited partnership (the "Operating Partnership" and,
together with the Trust, the "Company").  The Trust is the sole general
partner and also a limited partner of the Operating Partnership, with a
combined equity interest in the Operating Partnership of 93.1% at June
30, 1999.  The Company provides leasing, property management,
development, acquisition, construction management and design management
for a portfolio of industrial and office properties which are located
principally within the Southeastern, Mid-Atlantic and Midwestern United
States.

In 1998, the Company received $296.3 million in aggregate net proceeds
from the issuance of Common Shares and $292.1 million in aggregate net
proceeds from the issuance of unsecured notes.  The Company used the
aggregate net proceeds from the sale of Common Shares and the unsecured
notes to fund the Company's activities, including paying down the Credit
Facility, which funds acquisition and development activity.

On January 15, 1999, the Company closed on a $135 million, two-year
unsecured term loan.  The interest rate for the loan is 135 basis points
over LIBOR.

On April 20, 1999, the Company sold $250 million principal amount of
7.75% notes due 2009.  The aggregate net proceeds from such issuance was
approximately $246.0 million.

On July 28, 1999, the Company completed a private placement of 3.8
million Series B Cumulative Redeemable Preferred Units of the Operating
Partnership.  The Series B Preferred Units are payable at the rate of
9.25% per annum of the $25 liquidation preference, and are redeemable at
the option of the Company at any time on or after July 28, 2004 at $25
per share.

NOTE 3 - SEGMENT INFORMATION
- ----------------------------

Liberty Property Trust operates its portfolio of properties throughout
the Southeastern, Mid-Atlantic and Midwestern United States.  The
Company reviews performance of the portfolio on a geographical basis, as
such, the following regions are considered the Company's reportable
segments:  Southeastern Pennsylvania; New Jersey; Lehigh Valley,
Pennsylvania; Virginia; the Carolinas; Jacksonville, Florida; Detroit,
Michigan; and all others, which includes Maryland; Tampa, Florida; South
Florida; Minneapolis, Minnesota; and the United Kingdom.  The Company's
reportable segments are distinct business units which are each managed
separately in order to concentrate market knowledge within a
geographical area.  Within these reportable segments, the Company
derives its revenues from its two product types: industrial properties
and office properties.

The Company evaluates performance of the reportable segments based on
property-level net operating income, which is calculated as rental
revenue and operating expense reimbursement less rental property
expenses and real estate taxes.  The accounting policies of the
reportable segments are the same as those for the Company on a
consolidated basis.  The operating information by segment is as follows
(in thousands):

NOTE 2 - ORGANIZATION
- ---------------------

Liberty Property Trust (the "Trust") is a self-administered and self-
managed Maryland real estate investment trust (a "REIT").  Substantially
all of the Trust's assets are owned directly or indirectly, and
substantially all of the Trust's operations are conducted directly or
indirectly, by its subsidiary, Liberty Property Limited Partnership, a
Pennsylvania limited partnership (the "Operating Partnership" and,
together with the Trust and its consolidated subsidiaries, the
"Company").  The Trust is the sole general partner and also a limited
partner of the Operating Partnership, with a combined equity interest in
the Operating Partnership of 93.1% at June 30, 1999.  The Company
provides leasing, property management, acquisition, development,
construction management and design management for a portfolio of
industrial and office properties which are located principally within the
Southeastern, Mid-Atlantic and Midwestern United States.

In 1998, the Company received $296.3 million in aggregate net proceeds
from the issuance of Common Shares and $292.1 million in aggregate net
proceeds from the issuance of unsecured notes.  The Company used the
aggregate net proceeds from the sale of Common Shares and the unsecured
notes to fund the Company's activities, including paying down the Credit
Facility, which funds acquisition and development activity.

On January 15, 1999, the Company closed on a $135 million, two-year
unsecured term loan.  The interest rate for the loan is 135 basis points
over LIBOR.

On April 20, 1999, the Company sold $250 million principal amount of
7.75% notes due 2009.  The aggregate net proceeds from such issuance was
approximately $246.0 million.

million Series B Cumulative Redeemable Preferred Units of the Operating
Partnership.  The Series B Preferred Units are payable at the rate of
9.25% per annum of the $25 liquidation preference, and are redeemable at
the option of the Company at any time on or after July 28, 2004 at $25
per share.

NOTE 3 - SEGMENT INFORMATION
- ----------------------------

Liberty Property Limited Partnership operates its portfolio of
properties throughout the Southeastern, Mid-Atlantic and Midwestern
United States.  The Company reviews performance of the portfolio on a
geographical basis, as such, the following regions are considered the
Company's reportable segments:  Southeastern Pennsylvania; New Jersey;
Lehigh Valley, Pennsylvania; Virginia; the Carolinas; Jacksonville,
Florida; Detroit, Michigan; and all others which includes Maryland;
Tampa, Florida; South Florida; Minneapolis, Minnesota; and the United
Kingdom.  The Company's reportable segments are distinct business units
which are each managed separately in order to concentrate market
knowledge within a geographical area.  Within these reportable segments,
the Company derives its revenues from its two product types: industrial
and office properties.

The Company evaluates performance of the reportable segments based on
property-level net operating income, which is calculated as rental
revenue and operating expense reimbursement less rental property
expenses and real estate taxes.  The accounting policies of the
reportable segments are the same as those for the Company on a
consolidated basis.  The operating information by segment is as follows

RESULTS OF OPERATIONS
- ---------------------

The following discussion is based on the consolidated financial
statements of the Company.  It compares the results of operations of the
Company for the three and six months ended June 30, 1999 (unaudited) with
the results of operations of the Company for the three and six months
ended June 30, 1998 (unaudited).  As a result of the significant level of
acquisition, disposition and development activities by the Company in
1999 and 1998, the overall operating results of the Company during such
periods are not directly comparable.  However, certain data, including
the "Same Store" comparison, do lend themselves to direct comparison.  As
used herein, the term "Company" includes the Trust, the Operating
Partnership and their subsidiaries.

This information should be read in conjunction with the accompanying
consolidated financial statements and notes included elsewhere in this
report.

For the three and six months ended June 30, 1999 compared to the three
and six months ended June 30, 1998.
- -----------------------------------------------------------------------

Total revenue (principally rental revenue and operating expense
reimbursement) increased to $127.1 million from $91.4 million for the
three months ended June 30, 1999 compared to 1998, and increased to
$240.6 million from $174.0 million for the six months ended June 30, 1999
compared to 1998. These increases are primarily due to the increase in
the number of properties in operation during the respective periods.  As
of June 30, 1998, the Company had 540 properties in operation and, as of
June 30, 1999, the Company had 627 properties in operation. From January
1, 1998 through March 31, 1998, and from April 1, 1998 through June 30,
1998, the Company acquired or completed the development on 55 properties
and 48 properties, respectively, for Total Investments (as defined below)
of approximately $301.6 million and $224.8 million, respectively.  From
January 1, 1999 through March 31, 1999, and from April 1, 1999 through
June 30, 1999, the Company acquired or completed the development on 19
properties and 15 properties, respectively, for Total Investments of
approximately $71.2 million and $120.0 million, respectively. Offsetting
the increases in the number of properties acquired and developed and the
related Total Investments during the periods were property dispositions.
From January 1, 1998 through March 31, 1998, the Company did not sell any
properties.  From April 1, 1998 through June 30, 1998, the Company sold 5
properties for net proceeds of approximately $11.7 million.  From January
1, 1999 through March 31, 1999, and from April 1, 1999 through June 30,

- -20-


1999, the Company sold 2 and 14 properties, respectively, for net
proceeds of approximately $8.7 million and $51.3 million, respectively.
The "Total Investment" for a property is defined as the property's
purchase price plus closing costs and management's estimate, as
determined at the time of acquisition, of the cost of necessary building
improvements in the case of acquisitions, or land costs and land and
building improvement costs in the case of development projects, and where
appropriate, other development costs and carrying costs required to reach
rent commencement.

Rental property and real estate tax expenses increased to $30.7 million
from $24.2 million for the three months ended June 30, 1999 compared to
1998, and to $61.7 million from $46.2 million for the six months ended
June 30, 1999 compared to 1998. These increases are due to the increase
in the number of properties owned during the respective periods.

Property-level operating income for the "Same Store" properties
(properties owned as of January 1, 1998) increased to $110.5 million for
the six months ended June 30, 1999 from $106.9 million for the six months
ended June 30, 1998, with straightlining (which recognizes rental revenue
evenly over the life of the lease), and increased to $109.0 million for
the six months ended June 30, 1999 from $104.8 million for the six months
ended June 30, 1998, without straightlining.  These increases of 3.3% and
3.9%, respectively, are due to increases in the rental rates for the
properties.

Set forth below is a schedule comparing the property-level operating
income for the Same Store properties for the six month periods ended June
30, 1999 and 1998 (in thousands).

General and administrative expenses increased to $3.9 million for the
three months ended June 30, 1999 from $3.7 million for the three months
ended June 30, 1998, and to $7.9 million for the six months ended June
30, 1999 from $7.0 million for the six months ended June 30, 1998, due to
the increase in personnel and other related overhead costs necessitated
by the increase in the number of properties owned during the respective
periods.  These increases are somewhat mitigated by the benefit of
certain economies of scale experienced by the Company in owning and
operating the increased number of properties.

Depreciation and amortization expense increased to $20.4 million for the
three months ended June 30, 1999 from $16.5 million for the three months
ended June 30, 1998, and to $40.6 million for the six months ended June
30, 1999 from $30.7 million for the six months ended June 30, 1998.

- -21-


These increases are due to an increase in the number of properties owned
during the respective periods.

Interest expense increased to $25.8 million for the three months ended
June 30, 1999 from $18.9 million for the three months ended June 30,
1998, and to $49.6 million for the six months ended June 30, 1999 from
$35.4 million for the six months ended June 30, 1998.  These increases
are due to an increase in the average debt outstanding for the respective
periods which was $1,497.2 million for the second quarter of 1999
compared to $1,220.3 million for the second quarter of 1998, and $1,472.7
million for the first six months of 1999 compared to $1,133.6 million for
the first six months of 1998.  These increases are offset by decreases in
the weighted average interest rates for the periods, to 7.2% for the
second quarter June 30, 1999 from 7.3% for the second quarter June 30,
1998, and to 7.2% for the first six months of 1999 from 7.3% for the
first six months of 1998.

As a result of the foregoing, the Company's operating income increased to
$72.1 million for the three months ended June 30, 1999 from $47.0 million
for the three months ended June 30, 1998, and to $130.5 million for the
six months ended June 30, 1999 from $90.1 million for the six months
ended June 30, 1998.  In addition, income before minority interest
increased to $46.3 million for the three months ended June 30, 1999 from
$28.1 million for the three months ended June 30, 1998, and to $80.9
million for six months ended June 30, 1999 from $54.6 million for the six
months ended June 30, 1998.

LIQUIDITY AND CAPITAL RESOURCES

As of June 30, 1999, the Company had cash and cash equivalents of $33.6
million.

Net cash flow provided by operating activities increased to $131.2
million for the six months ended June 30, 1999 from $108.6 million for
the six months ended June 30, 1998.  This $22.6 million increase was
primarily due to the cash provided by the additional Operating Properties
in service during the latter period.

Net cash used in investing activities decreased to $128.4 million for the
six months ended June 30, 1999 from $526.2 million for the six months
ended June 30, 1998.  This decrease primarily resulted from
decreased acquisition activity in 1999, and an increase in property
dispositions.

Net cash provided by financing activities decreased to $16.4 million for
the six months ended June 30, 1999 from $402.9 million for the six months
ended June 30, 1998. This decrease is due to a decrease in the Company's
financing requirements consistent with its decrease in investing
activities.

The Company believes that its undistributed cash flow from operations is
adequate to fund its short-term liquidity requirements.

The Company funds its acquisitions and completed development with long-
term capital sources.  These activities may be funded on a temporary
basis through its $325.0 million unsecured line of credit (the "Credit
Facility"), which matures May 2000.

The interest rate on borrowings under the Credit Facility fluctuates
based upon the Company's leverage levels or ratings from Moody's Investor
Services, Inc. ("Moody's") and Standard & Poor's Rating's Group

- -22-


("Standard & Poor's"). Moody's and Standard & Poor's have assigned senior
debt ratings to the Company of Baa3 and BBB-, respectively.  At these
ratings, the interest rate for borrowings under the Credit Facility is
110 basis points over LIBOR.

As of June 30, 1999, $386.2 million in mortgage loans, $895.0 million in
unsecured notes and $135.0 million in an unsecured term loan were
outstanding.  The interest rates on $376.8 million of mortgage loans and
unsecured notes are fixed and range from 5.0% to 9.1%.  Interest rates on
$9.4 million of mortgage loans and the unsecured term loan float with
LIBOR or a municipal bond index, $2.8 million of which is subject to a
cap.  The weighted average remaining term for the mortgage loans,
unsecured notes and the unsecured term loan is 7.8 years. The scheduled
maturities of principal amortization of the Company's mortgage loans,
unsecured notes and the unsecured term loan outstanding and the related
weighted average interest rates are as follows (in thousands):

General

The Company believes that its existing sources of capital will provide
sufficient funds to finance its continued development and acquisition
activities.  The Company's need for capital has been somewhat reduced by
a decline in acquisition activity throughout the year, resulting from a
general marketplace decline in initial returns on acquisitions.  The
Company's existing sources of capital include the public debt and equity
markets, proceeds from property dispositions and net cash provided from
its operating activities.  Additionally, the Company expects to incur
variable rate debt, including borrowings under the Credit Facility, from
time to time.

In 1998, the Company received $296.3 million in aggregate net proceeds
from the issuance of Common Shares and $292.1 million in aggregate net
proceeds from the issuance of unsecured notes.  The Company used the
aggregate net proceeds from the sale of Common Shares and the unsecured
notes to fund the Company's activities, including paying down the Credit
Facility, which funds acquisition and development activity.

- -23-


On January 15, 1999, the Company closed a $135 million, two-year
unsecured term loan.  The interest rate for the loan is 135 basis points
over LIBOR.

On April 20, 1999, the Company sold $250 million principal amount of
7.75% notes due 2009.  The aggregate net proceeds from such issuance was
approximately $246.0 million.

On July 28, 1999, the Company completed a private placement of 3.8
million 9.25% Series B Cumulative Redeemable Preferred Units of the
Operating Partnership at a price of $25 per unit.  The Company used the
aggregate net proceeds of approximately $93.0 million from the sale of
the preferred units to repay outstanding borrowings under the Company's
term loan and to fund the Company's activities including paying down the
Credit Facility which funds acquisitions and development activity.

The Company has an effective S-3 shelf registration statement on file
with the Securities and Exchange Commission.  As of July 30, 1999, the
Company had the capacity pursuant to the Shelf Registration Statement to
issue $688.4 million in equity securities and the Operating Partnership
has the capacity to issue $108.0 million in debt securities.

Calculation of Funds from Operations

Management generally considers funds from operations (as defined below) a
useful financial performance measure of the operating performance of an
equity REIT, because, together with net income and cash flows, funds from
operations provides investors with an additional basis to evaluate the
ability of a REIT to incur and service debt and to fund acquisitions and
capital expenditures.  Funds from operations is defined by NAREIT as net
income or loss after preferred distributions (computed in accordance with
generally accepted accounting principles ("GAAP")), excluding gains (or
losses) from debt restructuring and sales of property, plus real estate-
related depreciation and amortization and minority interest and excluding
significant nonrecurring events that materially distort the comparative
measurement of the Company's performance over time.  Funds from
operations does not represent net income or cash flows from operations as
defined by GAAP and does not necessarily indicate that cash flows will be
sufficient to fund cash needs.  It should not be considered as an
alternative to net income as an indicator of the Company's operating
performance or to cash flows as a measure of liquidity.  Funds from
operations also does not represent cash flows generated from operating,
investing or financing activities as defined by GAAP.  Funds from
operations for the three and six months ended June 30, 1999 and June 30,
1998 are as follows (in thousands):

YEAR 2000

Background

In the past, many computer software programs were written using two
digits rather than four to define the applicable year.  As a result,
date-sensitive computer software may recognize a date using "00" as the
year 1900 rather than the year 2000.  This is generally referred to as
the Year 2000 issue.  If this situation occurs, the potential exists for
computer system failures or miscalculations by computer programs, which
could disrupt operations.

Approach

The Company has established a group to coordinate the Company's response
to the Year 2000 issue.  This group, which reports to the President and
Chief Operating Officer, includes the Company's MIS Director, a Vice-
President-Property Management and its General Counsel, as well as
support staff.  The Company is in the process of implementing a Year
2000 compliance program at the Company's offices and properties
consisting of the following phases:

      PHASE 1  Compilation of an inventory of information technology
(IT) and non-IT systems that may be sensitive to the Year 2000 problem.

      PHASE 2  Identification and prioritization of the critical systems
from the systems inventory compiled in Phase 1 and inquiries of third
parties with whom the Company does significant business (i.e., vendors,
service providers and certain tenants) as to the state of their Year
2000 readiness.

      PHASE 3   Analysis of critical systems to determine which systems
are not Year 2000 compliant and evaluation of the costs to repair or
replace those systems.

      PHASE 4   Repair or replace noncompliant systems and testing of
critical systems, where applicable.

Status

The Company's property management and accounting system uses four-digit
year fields and consequently is believed to be Year 2000 compliant.

Phases 1, 2, 3 and 4 are substantially complete but for the process of
making inquiries of significant third parties as to their Year 2000
readiness and testing of critical systems, which is ongoing.

Based upon the analysis conducted to date, the Company believes the
major critical systems at the Company's properties are currently
compliant.

Costs

The total cost to the Company of making its systems Year 2000 compliant
is currently estimated to be in the range of $200,000-$300,000.  The
majority of this cost relates to repairing certain software, testing
systems and retrofitting or replacing energy management systems at
certain of the properties.  The cost for the replacement of the
equipment and the software will be capitalized and depreciated over
their expected useful life.  To the extent existing hardware or software
is replaced, the Company will expense the cost as incurred.  This

- -25-


expense is included in the above cost estimate.  Furthermore, all costs
related to software modification, as well as all costs associated with
the Company's administration of its Year 2000 project, are being
expensed as incurred and are likewise included in the cost estimate
above.

Risks Associated with the Year 2000 Problem

The Company utilizes computer systems in many aspects of its business.
As noted, the Company's property management and accounting systems use
four-digit year fields and are believed to be Year 2000 compliant.
Additionally, with respect to the hardware and software systems utilized
by the Company in its management information systems, the Company's
assessment to date indicates that these systems are Year 2000 compliant
or can readily be made Year 2000 compliant on a stand-alone basis.
Testing of the operation of these systems together is ongoing.

The Company's also utilizes microprocessors which are imbedded in
systems which are part of the building operations (e.g., microprocessors
contained within the buildings' energy management systems or fire and
life safety systems).  In particular, Year 2000 problems in the HVAC,
elevator, security or other such systems at the properties could disrupt
operations at the affected properties.  The properties generally consist
of suburban office and industrial properties.  The properties are also
principally single-story and low-rise buildings.  The Company has
reviewed its building operating systems on a building-by-building basis.
 At this point, based on the status of its assessment, the Company does
not believe a material number of these systems will be non-compliant.
Additionally, many of these systems, which operate automatically, can be
operated manually and consequently in the event these systems experience
a failure as a result of the Year 2000 problem, the disruption caused by
such failure should not be material to the Company's operations.

The Company is also exposed to the risk that one or more of its vendors
or service providers could experience Year 2000 problems that impact the
ability of such vendor or service provider to provide goods and
services.  Though this is not considered as significant a risk with
respect to the suppliers of goods, due to the availability of
alternative suppliers, the disruption of certain services, such as
utilities, could, depending upon the extent of the disruption, have a
material adverse impact on the Company's operations.  To date, the
Company is not aware of any vendor or service provider Year 2000 issue
that management believes would have a material adverse impact on the
Company's operations.  However, the Company has no means of ensuring
that its vendors or service providers will be Year 2000 ready.  The
inability of vendors or service providers to complete their Year 2000
resolution process in a timely fashion could have a adverse impact on
the Company.  The effect of non-compliance by vendors or service
providers is not determinable at this time.

In addition, the Company is exposed to the risk that one or more of its
tenants could experience Year 2000 problems that impact the ability of
such tenant to pay its rent to the Company in a timely fashion.  The
Company does not believe that such a problem is likely to affect enough
tenants to pose a material problem for the Company.  To date, the
Company is not aware of any tenant Year 2000 issue that would have a
material adverse impact on the Company's operations.  However, the
Company has no means of ensuring that its tenants will be Year 2000
ready.  The inability of tenants to complete their Year 2000 resolution
process in a timely fashion could have an adverse impact on the Company.

- -26-


The effect of non-compliance by tenants is not determinable at this
time.

Widespread disruptions in the national or international economy,
including disruptions affecting the financial markets, resulting from
Year 2000 issues, or in certain industries, such as commercial or
investment banks, could also have an adverse impact on the Company.  The
likelihood and effect of such disruptions is not determinable at this
time.

Readers are cautioned that forward-looking statements contained in the
Year 2000 discussion should be read in conjunction with the Company's
disclosures regarding forward-looking statements previously disclosed.

INFLATION
- ---------

Inflation has remained relatively low during the last three years, and as
a result, it has not had a significant impact on the Company during this
period. The Credit Facility bears interest at a variable rate; therefore,
the amount of interest payable under the Credit Facility will be
influenced by changes in short-term interest rates, which tend to be
sensitive to inflation. To the extent an increase in inflation would
result in increased operating costs, such as in insurance, real estate
taxes and utilities, substantially all of the tenants' leases require the
tenants to absorb these costs as part of their rental obligations. In
addition, inflation also may have the effect of increasing market rental
rates.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes to the Company's exposure to market
risk since its Annual Report on Form 10-K for 1998.

Item 1.  Legal Proceedings

         None

Item 2.  Changes in Securities and Use of Proceeds

         On July 28, 1999, the Operating Partnership issued 3.8 million
9.25% Series B Cumulative Redeemable Preferred Units of Limited
Partnership Interest (the "Units").  The aggregate sale price of the
Units was $95.0 million.  The Units were sold to two institutional
investors in a private placement in reliance on the exemption from
registration under Section 4(2) of the Securities Act of 1933, as
amended.  The Units are convertible after ten years (or, under limited
circumstances, a shorter period of time), on a one-for-one basis, into
the 9.25% Series B Cumulative Redeemable Preferred Shares of Beneficial
Interest of the Trust (the "Preferred Shares"), which were authorized
for issuance by the Trust in connection with this transaction.  The
Units have identical rights, preferences and privileges as the Preferred
Shares.  The Units do not include any mandatory redemption or sinking
fund provisions.  The holders of the Units have certain rights to cause
the Trust to register the Preferred Shares pursuant to the terms of a
registration rights agreement entered into in connection with this
private placement.

         The net proceeds of the sale of the units, approximately $93.0
million, was used to repay the Company's term loan and to fund other
Company activities, including paying down the outstanding balance under
the Credit Facility.

         In connection with the sale of the Units, the Operating
Partnership amended its Second Restated and Amended Agreement of Limited
Partnership pursuant to the First Amendment thereto, filed as Exhibit
3.1.1 to this Report.  The Articles Supplementary to the Amended and
Restated Declaration of Trust of the Trust creating the Preferred Shares
are filed as Exhibit 3.1.2 to this Report.

         The Units are pari passu with the 8.80% Series A Cumulative
Redeemable Preferred Units of Limited Partnership of the Operating
Partnership, and senior to all other units of limited partnership
interest of the Operating Partnership.  The Preferred Shares are pari
passu with the 8.80% Series A Cumulative Redeemable Preferred Shares of
Beneficial Interest of the Trust, and senior to the Common Shares of
Beneficial Interest of the Trust.
