MACK-CALI REALTY CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN THOUSANDS, EXCEPT PER
SHARE/UNIT AMOUNTS)
================================================================================

1. ORGANIZATION AND BASIS OF PRESENTATION

ORGANIZATION

Mack-Cali Realty Corporation, a Maryland corporation, and subsidiaries (the
"Company") is a fully-integrated, self-administered, self-managed real estate
investment trust ("REIT") providing leasing, management, acquisition,
development, construction and tenant-related services for its properties. As of
June 30, 2001, the Company owned or had interests in 269 properties, plus
developable land (collectively, the "Properties"). The Properties aggregate
approximately 28.5 million square feet, and are comprised of 164 office
buildings and 93 office/flex buildings totaling approximately 28.1 million
square feet (which includes seven office buildings and one office/flex building
aggregating 1.2 million square feet, owned by unconsolidated joint ventures in
which the Company has investment interests), six industrial/warehouse buildings
totaling approximately 387,400 square feet, one multi-family residential complex
consisting of 124 units, two stand-alone retail properties and three land
leases. The Properties are located in 11 states, primarily in the Northeast,
plus the District of Columbia.

BASIS OF PRESENTATION

The accompanying consolidated financial statements include all accounts of the
Company, its majority-owned and/or controlled subsidiaries, which consist
principally of Mack-Cali Realty, L.P. ("Operating Partnership"). See Investments
in Unconsolidated Joint Ventures in Note 2 for the Company's treatment of
unconsolidated joint venture interests. All significant intercompany accounts
and transactions have been eliminated.

The preparation of financial statements in conformity with generally accepted
accounting principles ("GAAP") requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

2. SIGNIFICANT ACCOUNTING POLICIES

RENTAL PROPERTY

Rental properties are stated at cost less accumulated depreciation and
amortization. Costs directly related to the acquisition and development of
rental properties are capitalized. Capitalized development costs include
interest, property taxes, insurance and other project costs incurred during the
period of development. Included in total rental property is
construction-in-progress of $141,623 and $188,077 as of June 30, 2001 and
December 31, 2000, respectively. Ordinary repairs and maintenance are expensed
as incurred; major replacements and betterments, which improve or extend the
life of the asset, are capitalized and depreciated over their estimated useful
lives. Fully-depreciated assets are removed from the accounts.

Properties are depreciated using the straight-line method over the estimated
useful lives of the assets. The estimated useful lives are as follows:

<Table>
                                            
Leasehold interests                                        Remaining lease term

                                               the related lease or useful life

On a periodic basis, management assesses whether there are any indicators that
the value of the real estate properties may be impaired. A property's value is
impaired only if management's estimate of the aggregate future cash flows
(undiscounted and without interest charges) to be generated by the property are
less than the carrying value of the property. To the extent impairment has
occurred, the loss shall be measured as the excess of the carrying amount of the
property over the fair value of the property. Management does not believe that
the value of any of its rental properties is impaired.

When assets are identified by management as held for sale, the Company
discontinues depreciating the assets and estimates the sales price, net of
selling costs, of such assets. If, in management's opinion, the net sales price
of the assets which have been identified for sale is less than the net book
value of the assets, a valuation allowance is established. See Note 7.

INVESTMENTS IN UNCONSOLIDATED JOINT VENTURES

The Company accounts for its investments in unconsolidated joint ventures under
the equity method of accounting as the Company exercises significant influence,
but does not control these entities. These investments are recorded initially at
cost, as Investments in Unconsolidated Joint Ventures, and subsequently adjusted
for equity in earnings and cash contributions and distributions. Any difference
between the carrying amount of these investments on the balance sheet of the
Company and the underlying equity in net assets is amortized as an adjustment to
equity in earnings of unconsolidated joint ventures over 40 years. See Note 4.

PARTIALLY-OWNED PROPERTIES

The Company controlled operations of the partially-owned properties and has
consolidated the financial position and results of operations of partially-owned
properties in the financial statements of the Company. The equity interests of
the other members are reflected as minority interests: partially-owned
properties in the consolidated financial statements of the Company.

CASH AND CASH EQUIVALENTS

All highly liquid investments with a maturity of three months or less when
purchased are considered to be cash equivalents.

DEFERRED FINANCING COSTS

Costs incurred in obtaining financing are capitalized and amortized on a
straight-line basis, which approximates the effective interest method, over the
term of the related indebtedness. Amortization of such costs is included in
interest expense and was $1,161 and $901 for the three months ended June 30,
2001 and 2000, respectively, and $2,282 and $1,802 for the six months ended June
30, 2001 and 2000, respectively.

DEFERRED LEASING COSTS

Costs incurred in connection with leases are capitalized and amortized on a
straight-line basis over the terms of the related leases and included in
depreciation and amortization. Unamortized deferred leasing costs are charged to
amortization expense upon early termination of the lease. Certain employees of
the Company provide leasing services to the Properties and receive compensation
based on space leased. The portion of such compensation, which is capitalized
and amortized, approximated $863 and $896 for the three months ended June 30,
2001 and 2000, respectively, and $1,603 and $1,589 for the six months ended June
30, 2001 and 2000, respectively.

REVENUE RECOGNITION

Base rental revenue is recognized on a straight-line basis over the terms of the
respective leases. Unbilled rents receivable represents the amount by which
straight-line rental revenue exceeds rents currently billed in accordance with
the lease agreements. Parking and other revenue includes income from parking
spaces leased to tenants, income from tenants for additional services provided
by the Company, income from tenants for early lease terminations and income from
managing properties for third parties. Rental income on residential property
under operating leases having terms generally of one year or less is recognized
when earned.

Reimbursements are received from tenants for certain costs as provided in the
lease agreements. These costs generally include real estate taxes, utilities,
insurance, common area maintenance and other recoverable costs. See Note 14.

INCOME AND OTHER TAXES

The Company has elected to be taxed as a REIT under Sections 856 through 860 of
the Internal Revenue Code of 1986, as amended (the "Code"). As a REIT, the
Company generally will not be subject to corporate federal income tax on net
income that it currently distributes to its shareholders, provided that the
Company, for its taxable years beginning prior to January 1, 2001, satisfies
certain organizational and operational requirements including the requirement to
distribute at least 95 percent of its REIT taxable income to its shareholders.
For its taxable years beginning after December 31, 2000, as a result of recent
amendments to the Code, the Company is required to distribute at least 90
percent of its REIT taxable income to its shareholders. Effective January 1,
2001, the Company has elected to treat certain of its corporate subsidiaries as
taxable REIT subsidiaries ("TRS"). In general, a TRS of the Company may perform
additional services for tenants of the Company and generally may engage in any
real estate or non-real estate related business (except for the operation or
management of health care facilities or lodging facilities or the providing to
any person, under a franchise, license or otherwise, rights to any brand name
under which any lodging facility or health care facility is operated). A TRS is
subject to corporate federal income tax. If the Company fails to qualify as a
REIT in any taxable year, the Company will be subject to federal income tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate tax rates. The Company is subject to certain state and local
taxes.

DERIVATIVE INSTRUMENTS

The Company has adopted Statement of Financial Accounting Standards No. 133,
Accounting for Derivative Instruments and Hedging Activities ("FASB No. 133") as
of January 1, 2001. Due to its limited use of derivative instruments, adoption
of FASB No. 133 did not have a material impact on the Company's financial
statements.

Interest rate contracts are utilized by the Company to reduce interest rate
risks. The Company does not hold or issue derivative financial instruments for
trading purposes. The differentials to be received or paid under contracts
designated as hedges are recognized over the life of the contracts as
adjustments to interest expense.

In certain situations, the Company uses forward treasury lock agreements to
mitigate the potential effects of changes in interest rates for prospective
transactions. Gains and losses are deferred and amortized as adjustments to
interest expense over the remaining life of the associated debt to the extent
that such debt remains outstanding.

EARNINGS PER SHARE

In accordance with the Statement of Financial Accounting Standards No. 128
("FASB No. 128"), the Company presents both basic and diluted earnings per share
("EPS"). Basic EPS excludes dilution and is computed by dividing net income
available to common stockholders by the weighted average number of shares
outstanding for the period. Diluted EPS reflects the potential dilution that
could occur if securities or other contracts to issue common stock were
exercised or converted into common stock, where such exercise or conversion
would result in a lower EPS amount.

DIVIDENDS AND DISTRIBUTIONS PAYABLE

The dividends and distributions payable at June 30, 2001 represents dividends
payable to shareholders of record as of July 5, 2001 (56,308,064 shares),
distributions payable to minority interest common unitholders (7,955,525 common
units) on that same date and preferred distributions payable to preferred
unitholders (220,340 preferred units) for the second quarter 2001. The second
quarter 2001 dividends and common unit distributions of $0.61 per share and per
common unit, as well as the second quarter preferred unit distribution of
$17.6046 per preferred unit, were approved by the Board of Directors on June 21,
2001 and paid on July 23, 2001.

The dividends and distributions payable at December 31, 2000 represents
dividends payable to shareholders of record as of January 4, 2001 (56,982,893
shares), distributions payable to minority interest common unitholders
(7,963,725 common units) on that same date and preferred distributions payable
to preferred unitholders (220,340 preferred units) for the fourth quarter 2000.
The fourth quarter 2000 dividends and common unit distributions of $0.61 per
share and per common unit, as well as the fourth quarter preferred unit
distribution of $17.6046 per preferred unit, were approved by the Board of
Directors on December 20, 2000 and paid on January 22, 2001.

UNDERWRITING COMMISSIONS AND COSTS

Underwriting commissions and costs incurred in connection with the Company's
stock offerings are reflected as a reduction of additional paid-in capital.

STOCK OPTIONS

The Company accounts for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," and related Interpretations ("APB No. 25"). Under
APB No. 25, compensation cost is measured as the excess, if any, of the quoted
market price of the Company's stock at the date of grant over the exercise price
of the option granted. Compensation cost for stock options, if any, is
recognized ratably over the vesting period. The Company's policy is to grant
options with an exercise price equal to the quoted closing market price of the
Company's stock on the business day preceding the grant date. Accordingly, no
compensation cost has been recognized under the Company's stock option plans for
the granting of stock options. See Note 15.

9. REVOLVING CREDIT FACILITIES

2000 UNSECURED FACILITY

On June 22, 2000, the Company obtained an unsecured revolving credit facility
("2000 Unsecured Facility") with a current borrowing capacity of $800,000 from a
group of 24 lenders. The interest rate on outstanding borrowings under the
credit line is currently the London Inter-Bank Offered Rate ("LIBOR") (3.86
percent at June 30, 2001) plus 80 basis points. The Company may instead elect an
interest rate representing the higher of the lender's prime rate or the Federal
Funds rate plus 50 basis points. The 2000 Unsecured Facility also requires a 20
basis point facility fee on the current


                                       20
<Page>

borrowing capacity payable quarterly in arrears. In the event of a change in the
Company's unsecured debt rating, the interest rate and facility fee will be
changed on a sliding scale. Subject to certain conditions, the Company has the
ability to increase the borrowing capacity of the credit line up to $1,000,000.
The 2000 Unsecured Facility matures in June 2003, with an extension option of
one year, which would require a payment of 25 basis points of the then borrowing
capacity of the credit line upon exercise.

The terms of the 2000 Unsecured Facility include certain restrictions and
covenants which limit, among other things, the payment of dividends (as
discussed below), the incurrence of additional indebtedness, the incurrence of
liens and the disposition of assets, and which require compliance with financial
ratios relating to the maximum leverage ratio, the maximum amount of secured
indebtedness, the minimum amount of tangible net worth, the minimum amount of
debt service coverage, the minimum amount of fixed charge coverage, the maximum
amount of unsecured indebtedness, the minimum amount of unencumbered property
debt service coverage and certain investment limitations. The dividend
restriction referred to above provides that, except to enable the Company to
continue to qualify as a REIT under the Code, the Company will not during any
four consecutive fiscal quarters make distributions with respect to common stock
or other equity interests in an aggregate amount in excess of 90 percent of
funds from operations (as defined) for such period, subject to certain other
adjustments.

PRUDENTIAL FACILITY

The Company had a revolving credit facility ("Prudential Facility") with
Prudential Securities Corp. ("PSC") in the amount of $100,000, which bore
interest at 110 basis points over one-month LIBOR, with a maturity date of
June 29, 2001. The Prudential Facility was a recourse liability of the
Operating Partnership and was secured by the Company's equity interest in
Harborside Plazas 2 and 3. The Prudential Facility limited the ability of the
Operating Partnership to make any distributions during any fiscal quarter in
an amount in excess of 100 percent of the Operating Partnership's available
funds from operations (as defined) for the immediately preceding fiscal
quarter (except to the extent such excess distributions or dividends are
attributable to gains from the sale of the Operating Partnership's assets or
are required for the Company to maintain its status as a REIT under the
Code); provided, however, that the Operating Partnership may make
distributions and pay dividends in excess of 100 percent of available funds
from operations (as defined) for the preceding fiscal quarter for not more
than three consecutive quarters. In addition to the foregoing, the Prudential
Facility limited the liens placed upon the subject property and certain
collateral, the use of proceeds from the Prudential Facility, and the
maintenance of ownership of the subject property and assets derived from said
ownership. The Company repaid in full and terminated the Prudential Facility
on June 29, 2001.

SUMMARY

As of June 30, 2001 and December 31, 2000, the Company had outstanding
borrowings of $76,500 and $348,840, respectively, under its revolving credit
facilities. The total outstanding borrowings were from the 2000 Unsecured
Facility, with no outstanding borrowings under the Prudential Facility.

OTHER

On June 27, 2000, both Brant Cali and John R. Cali resigned their positions
as officers of the Company and Brant Cali resigned as a director of the
Company. John R. Cali was appointed to the Board of Directors of the Company
to take the seat previously held by Brant Cali. As required by Brant Cali and
John R. Cali's employment agreements with the Company: (i) the Company paid
$2,820 and $2,806 (less applicable withholding) to Brant Cali and John R.
Cali, respectively; (ii) all options to acquire shares of the Company's
common stock and Restricted Stock Awards (as hereinafter defined) held by
Brant Cali and John R. Cali became fully vested on the effective date of
their resignations from the Company. All costs associated with Brant Cali and
John R. Cali's resignations, which totaled approximately $9,228, are included
in non-recurring charges for the six months ended June 30, 2000.

The Company is a defendant in certain litigation arising in the normal course of
business activities. Management does not believe that the resolution of these
matters will have a materially adverse effect upon the Company.

14. TENANT LEASES

The Properties are leased to tenants under operating leases with various
expiration dates through 2016. Substantially all of the leases provide for
annual base rents plus recoveries and escalation charges based upon the tenant's
proportionate share of and/or increases in real estate taxes and certain
operating costs, as defined, and the pass through of charges for electrical
usage.

15. STOCKHOLDERS' EQUITY

To maintain its qualification as a REIT, not more than 50 percent in value of
the outstanding shares of the Company may be owned, directly or indirectly, by
five or fewer individuals at any time during the last half of any taxable year
of the Company, other than its initial taxable year (defined to include certain
entities), applying certain constructive ownership rules. To help ensure that
the Company will not fail this test, the Company's Articles of Incorporation
provide for, among other things, certain restrictions on the transfer of the
common stock to prevent further concentration of stock ownership. Moreover, to
evidence compliance with these requirements, the Company must maintain records
that disclose the actual ownership of its outstanding common stock and will
demand written statements each year from the holders of record of designated
percentages of its common stock requesting the disclosure of the beneficial
owners of such common stock.

COMMON STOCK REPURCHASES

On September 13, 2000, the Board of Directors authorized the Company to purchase
up to $150,000 of the Company's outstanding common stock ("Repurchase Program").
The Company purchased for constructive retirement 2,026,300 shares of its
outstanding common stock for an aggregate cost of approximately $55,514 from
September 13, 2000 through December 31, 2000.

Under the Repurchase Program, the Company purchased for constructive retirement
881,500 shares of its outstanding common stock for an aggregate cost of
approximately $24,056 for the six months ended June 30, 2001.

the 2000 Employee Plan and Employee Plan in 1996, 1997, 1998, 1999 and 2000
become exercisable over a five-year period. All stock options granted under both
the 2000 Director Plan and Director Plan become exercisable in one year. All

EARNINGS PER SHARE

FASB No. 128 requires a dual presentation of basic and diluted EPS on the face
of the income statement for all companies with complex capital structures even
where the effect of such dilution is not material. Basic EPS excludes dilution
and is computed by dividing net income available to common stockholders by the
weighted average number of shares outstanding for the period. Diluted EPS
reflects the potential dilution that could occur if securities or other
contracts to issue common stock were exercised or converted into common stock.

The following information presents the Company's results for the three and six
month periods ended June 30, 2001 and 2000 in accordance with FASB No. 128:

</Table>

Base rents for the Same-Store Properties increased $4.0 million, or 3.2 percent,
for 2001 as compared to 2000, due primarily to rental rate increases in 2001.
Escalations and recoveries from tenants for the Same-Store Properties decreased
$1.1 million, or 7.8 percent, for 2001 over 2000, due to the recovery of a
decreased amount of total property expenses in 2001, as well as increased
settle-up billings during the second quarter 2000. Parking and other income for
the Same-Store Properties decreased $3.0 million, or 49.2 percent, due primarily
to fewer lease termination fees in 2001.

Real estate taxes on the Same-Store Properties increased $0.1 million, or 1.0
percent, for 2001 as compared to 2000, due primarily to property tax rate
increases in certain municipalities in 2001. Utilities for the Same-Store
Properties increased $0.6 million, or 6.2 percent, for 2001 as compared to 2000,
due primarily to increased gas rates. Operating services for the Same-Store
Properties increased $0.5 million, or 2.7 percent, due primarily to an increase
in maintenance costs in 2001.

Equity in earnings of unconsolidated joint ventures increased $1.0 million, or
90.4 percent, for 2001 as compared to 2000. This is due primarily to properties
developed by joint ventures being placed in service during 2000 and higher
occupancies at certain properties in 2001 (see Note 4 to the Financial
Statements).

Interest income decreased $1.5 million, or 76.3 percent, for 2001 as compared to
2000. This decrease was due primarily to additional interest income in 2000 on
investment of proceeds from the Dispositions in cash and cash equivalents.

General and administrative increased by $1.7 million, or 32.9 percent, for 2001
as compared to 2000. This increase is due primarily to increased professional
fees, mostly on account of costs for transactions not consummated, and
increased payroll and related costs in 2001.

Depreciation and amortization decreased by $1.0 million, or 4.3 percent, for
2001 over 2000. Of this decrease, $1.7 million, or 7.4 percent, is attributable
to the Same-Store Properties, and $0.7 million, or 3.1 percent, is due to the
Dispositions, partially offset by an increase of $1.4 million, or 6.2 percent,
due to the Acquired Properties.

Interest expense increased $1.7 million, or 6.4 percent, for 2001 as compared to
2000. This increase is due primarily to the replacement in early 2001 of
short-term credit facility borrowings with higher, long-term fixed rate
unsecured debt.

Income before realized and unrealized gain on disposition of rental property and
minority interests increased to $47.2 million in 2001 from $40.2 million in
2000. The increase of approximately $7.0 million is due to the factors discussed
above.

Net income decreased by $36.6 million, from $94.3 million in 2000 to $57.7
million in 2001. This decrease was a result of a gain on sale of rental property
in 2000 of $73.9 million, which was partially offset by a gain on sale of rental
property in 2001 of $22.5 million, an increase in income before realized and
unrealized gain on disposition of rental property and minority interests of $7.0
million in 2001 as compared to 2000, and a decrease in minority interests of
$7.8 million in 2001.

</Table>

Base rents for the Same-Store Properties increased $9.3 million, or 3.8 percent,
for 2001 as compared to 2000, due primarily to rental rate increases in 2001.
Escalations and recoveries from tenants for the Same-Store Properties decreased
$1.8 million, or 5.9 percent, for 2001 over 2000, due to the recovery of a
decreased amount of total property expenses in 2001, as well as increased
settle-up billings in 2000. Parking and other income for the Same-Store
Properties decreased $3.7 million, or 39.0 percent, due primarily to fewer lease
termination fees in 2001.

Real estate taxes on the Same-Store Properties increased $0.5 million, or 1.6
percent, for 2001 as compared to 2000, due primarily to property tax rate
increases in certain municipalities in 2001. Utilities for the Same-Store
Properties increased $1.9 million, or 9.4 percent, for 2001 as compared to 2000,
due primarily to increased gas rates. Operating services for the Same-Store
Properties increased $1.0 million, or 3.0 percent, due primarily to an increase
in maintenance costs in 2001.

Equity in earnings of unconsolidated joint ventures increased $3.2 million, or
146.8 percent, for 2001 as compared to 2000. This is due primarily to properties
developed by joint ventures being placed in service during 2000 and higher
occupancies at certain properties (see Note 4 to the Financial Statements).

Interest income decreased $1.2 million, or 51.7 percent, for 2001 as compared to
2000. This decrease was due primarily to additional interest income in 2000 on
investment of proceeds from the Dispositions in cash and cash equivalents.

General and administrative increased by $1.6 million, or 14.1 percent, for
2001 as compared to 2000. This increase is due primarily to increased
professional fees, mostly on account of costs for transactions not
consummated, and increased payroll and related costs in 2001.

Depreciation and amortization decreased by $0.3 million, or 0.7 percent, for
2001 over 2000. Of this increase, $2.6 million, or 5.9 percent, is due to the
Acquired Properties, partially offset by a decrease of $1.4 million, or 3.2
percent, due to the Dispositions and $0.9 million, or 2.0 percent, attributable
to the Same-Store Properties.

Interest expense increased $3.7 million, or 6.9 percent, for 2001 as compared to
2000. This increase is due primarily to the replacement in 2001 of short-term
credit facility borrowings with higher, long-term fixed rate unsecured debt.

Income before realized gains and unrealized losses on disposition of rental
property and minority interests increased to $90.7 million in 2001 from $85.6
million in 2000. The increase of approximately $5.1 million is due to the
factors discussed above.

Net income decreased by $56.5 million, from $130.9 million in 2000 to $74.4
million in 2001. This decrease was a result of a gain on sale of rental property
of $76.2 million. This was partially offset by a gain on sale of rental property
of $2.0 million in 2001, an increase in income before realized gains and
unrealized losses on disposition of rental property and minority interests of
$5.1 million, and a decrease in minority interests of $12.6 million in 2001.

LIQUIDITY AND CAPITAL RESOURCES

STATEMENT OF CASH FLOWS

During the six months ended June 30, 2001, the Company generated $133.0 million
in cash flows from operating activities, and together with $586.8 million in
borrowings from the Company's senior unsecured notes, revolving credit
facilities and additional mortgage financing, $44.8 million in proceeds from
sales of rental property, $19.1 million in distributions received from
unconsolidated joint ventures, $6.0 million in proceeds from repayment of a
mortgage note receivable and $2.4 million in proceeds from stock options
exercised used an aggregate of approximately $792.1 million to acquire
properties and land parcels and pay for other tenant and building improvements
totaling $148.1 million, repay outstanding borrowings on its revolving credit
facilities and other mortgage debt of $494.7 million, pay quarterly dividends
and distributions of $87.0 million, invest $24.5 million in unconsolidated joint
ventures, pay financing costs of $3.2 million, repurchase 881,500 shares of its
outstanding common stock for $24.1 million, add $0.9 million to restricted cash
and add $9.6 million to cash and cash equivalents.

CAPITALIZATION

The Company has a focused strategy geared to attractive opportunities in
high-barrier-to-entry markets, primarily predicated on the Company's strong
presence in the Northeast region and, to a lesser extent, certain markets in
California. The Company plans to sell substantially all of its properties
located in the Southwestern and Western regions, using such proceeds to invest
in property acquisitions and development projects in its core Northeast markets,
as well as to repay debt and fund stock repurchases.

Consistent with its strategy, in the fourth quarter 2000, the Company started
construction of a 980,000 square-foot office property, to be known as Plaza 5,
at its Harborside Financial Center office complex in Jersey City, Hudson County,
New Jersey. The total cost of the project is currently projected to be
approximately $260 million and is anticipated to be completed in late 2002.
Additionally, in the fourth quarter 2000, the Company, through a joint venture,
started construction of a 575,000 square-foot office property, to be known as
Plaza 10, on land owned by the joint venture located adjacent to the Company's
Harborside complex. The total cost of this project is currently projected to be
approximately $140 million and is anticipated to be completed in late 2002.
Plaza 10 is 100 percent pre-leased to Charles Schwab & Co. Inc. for a 15-year
term. The lease agreement obligates the Company, among other things, to deliver
space to the tenant by required timelines and offers expansion options, at the
tenant's election, to additional space in any adjacent Harborside projects. Such
options may obligate the Company to construct an additional building at
Harborside if vacant space is not available in any of its existing Harborside
properties. Should the Company be unable to or choose not to provide such
expansion space, the Company could be liable to Schwab for its actual damages,
in no event to exceed $15.0 million. The Company expects to finance its funding
requirements under both Plazas 5 and 10 projects through drawing on its
revolving credit facilities, construction financing, or through joint venture
arrangements.

On August 6, 1998, the Board of Directors of the Company authorized a Repurchase
Program under which the Company was permitted to purchase up to $100.0 million
of the Company's outstanding common stock. Under the Repurchase Program, the
Company purchased for constructive retirement 1,869,200 shares of its
outstanding common stock for an aggregate cost of approximately $52.6 million
through September 12, 2000.

On September 13, 2000, the Board of Directors authorized an increase to the
Repurchase Program under which the Company is permitted to purchase up to an
additional $150.0 million of the Company's outstanding common stock above the
$52.6 million that had previously been purchased. From that date through July
31, 2001, the Company purchased for constructive retirement 2.9 million shares
of its outstanding common stock for an aggregate cost of approximately $79.7
million under the Repurchase Program. The Company has authorization to
repurchase up to an additional $70.3


                                       33
<Page>

million of its outstanding common stock which it may repurchase from time to
time in open market transactions at prevailing prices or through privately
negotiated transactions.

As of June 30, 2001, the Company's total indebtedness of $1.7 billion (weighted
average interest rate of 7.27 percent) was comprised of $108.7 million of
revolving credit facility borrowings and other variable rate mortgage debt
(weighted average rate of 5.07 percent) and fixed rate debt of $1.6 billion
(weighted average rate of 7.42 percent).

As of June 30, 2001, the Company had outstanding borrowings of $76.5 million
under its 2000 Unsecured Facility (with aggregate borrowing capacity of $800.0
million). The interest rate on outstanding borrowings under the 2000 Unsecured
Facility is currently LIBOR plus 80 basis points. The Company may instead elect
an interest rate representing the higher of the lender's prime rate or the
Federal Funds rate plus 50 basis points. The 2000 Unsecured Facility also
requires a 20 basis point facility fee on the current borrowing capacity payable
quarterly in arrears. In the event of a change in the Company's unsecured debt
rating, the interest and facility fee rate will be changed on a sliding scale.
Subject to certain conditions, the Company has the ability to increase the
borrowing capacity of the 2000 Unsecured Facility up to $1.0 billion. The 2000
Unsecured Facility matures in June 2003, with an extension option of one year,
which would require a payment of 25 basis points of the then borrowing capacity
of the credit line upon exercise. The Company believes that the 2000 Unsecured
Facility is sufficient to meet its revolving credit facility needs.

The terms of the 2000 Unsecured Facility include certain restrictions and
covenants which limit, among other things, the payment of dividends (as
discussed below), the incurrence of additional indebtedness, the incurrence of
liens and the disposition of assets, and which require compliance with financial
ratios relating to the maximum leverage ratio, the maximum amount of secured
indebtedness, the minimum amount of tangible net worth, the minimum amount of
debt service coverage, the minimum amount of fixed charge coverage, the maximum
amount of unsecured indebtedness, the minimum amount of unencumbered property
debt service coverage and certain investment limitations. The dividend
restriction referred to above provides that, except to enable the Company to
continue to qualify as a REIT under the Code, the Company will not during any
four consecutive fiscal quarters make distributions with respect to common stock
or other equity interests in an aggregate amount in excess of 90 percent of
funds from operations (as defined) for such period, subject to certain other
adjustments.

On January 29, 2001, the Operating Partnership issued $300.0 million face amount
of 7.75 percent senior unsecured notes due February 15, 2011 with interest
payable semi-annually in arrears. The total proceeds from the issuance (net of
selling commissions and discount) of approximately $296.3 million were used to
pay down outstanding borrowings under the 2000 Unsecured Facility, as defined in
Note 9 to the Financial Statements. The senior unsecured notes were issued at a
discount of approximately $1.7 million.

The terms of the Operating Partnership's unsecured debt include certain
restrictions and covenants which require compliance with financial ratios
relating to the maximum amount of debt leverage, the maximum amount of secured
indebtedness, the minimum amount of debt service coverage and the maximum amount
of unsecured debt as a percent of unsecured assets.

The Company has three investment grade credit ratings. Standard & Poor's Rating
Services ("S&P") and Fitch, Inc. ("Fitch") have each assigned their BBB rating
to existing and prospective senior unsecured debt of the Operating Partnership.
S&P and Fitch have also assigned their BBB- rating to prospective preferred
stock offerings of the Company. Moody's Investors Service has assigned its Baa3
rating to the existing and prospective senior unsecured debt of the Operating
Partnership and its Ba1 rating to prospective preferred stock offerings of the
Company.

On May 18, 2001, the Company obtained $70.0 million in additional mortgage
financing secured by Harborside Financial Center Plazas II and III from the
existing lender. The 7.42 percent interest only financing matures concurrent
with the existing financing on January 1, 2006. The total financing secured by
Harborside Financial Center Plazas II and III of $163.9 million at June 30,
2001, has a weighted average interest rate of 7.36 percent. Proceeds from the
financing were used to pay down the outstanding borrowings on the 2000 Unsecured
Facility.

As of June 30, 2001, the Company had 236 unencumbered properties, totaling 21.3
million square feet, representing 77.3 percent of the Company's total portfolio
on a square footage basis.


                                       34

The Company has an effective shelf registration statement with the SEC for an
aggregate amount of $2.0 billion in equity securities of the Company. The
Company and Operating Partnership also have an effective shelf registration
statement with the SEC for an aggregate of $2.0 billion in debt securities,
preferred stock and preferred stock represented by depositary shares, under
which the Operating Partnership has issued an aggregate of $1.1 billion of
unsecured debt.

Historically, rental revenue has been the principal source of funds to pay
operating expenses, debt service and capital expenditures, excluding
non-recurring capital expenditures. Management believes that the Company will
have access to the capital resources necessary to expand and develop its
business. To the extent that the Company's cash flow from operating activities
is insufficient to finance its non-recurring capital expenditures such as
property acquisition and construction project costs and other capital
expenditures, the Company expects to finance such activities through borrowings
under its revolving credit facilities and other debt and equity financing.

The Company expects to meet its short-term liquidity requirements generally
through its working capital, net cash provided by operating activities and from
the 2000 Unsecured Facility. The Company is frequently examining potential
property acquisitions and construction projects and, at any given time, one or
more of such acquisitions or construction projects may be under consideration.
Accordingly, the ability to fund property acquisitions and construction projects
is a major part of the Company's financing requirements. The Company expects to
meet its financing requirements through funds generated from operating
activities, proceeds from property sales, long-term or short-term borrowings
(including draws on the Company's revolving credit facilities) and the issuance
of additional debt or equity securities.

As of June 30, 2001, the Company's total debt had a weighted average term to
maturity of approximately 5.3 years. The Company does not intend to reserve
funds to retire the Company's unsecured corporate debt or its mortgages and
loans payable upon maturity. Instead, the Company will seek to refinance such
debt at maturity or retire such debt through the issuance of additional equity
or debt securities. The Company is reviewing various refinancing options,
including the issuance of additional unsecured debt, preferred stock, and/or
obtaining additional mortgage debt, some or all of which may be completed during
2001. The Company anticipates that its available cash and cash equivalents and
cash flows from operating activities, together with cash available from
borrowings and other sources, will be adequate to meet the Company's capital and
liquidity needs both in the short and long-term. However, if these sources of
funds are insufficient or unavailable, the Company's ability to make the
expected distributions discussed below may be adversely affected.

To maintain its qualification as a REIT, the Company must make annual
distributions to its stockholders of at least 90 percent of its REIT taxable
income, determined without regard to the dividends paid deduction and by
excluding net capital gains. Moreover, the Company intends to continue to make
regular quarterly distributions to its stockholders which, based upon current
policy, in the aggregate would equal approximately $139.1 million on an
annualized basis. However, any such distribution, whether for federal income tax
purposes or otherwise, would only be paid out of available cash after meeting
both operating requirements and scheduled debt service on mortgages and loans
payable.

FUNDS FROM OPERATIONS

The Company considers funds from operations ("FFO"), after adjustment for
straight-lining of rents and non-recurring charges, one measure of REIT
performance. Funds from operations is defined as net income (loss) before
minority interest of unitholders, computed in accordance with generally accepted
accounting principles ("GAAP"), excluding gains (or losses) from debt
restructuring, other extraordinary items, and realized gains and unrealized
losses on disposition of depreciable rental property, plus real estate-related
depreciation and amortization. Funds from operations should not be considered as
an alternative to net income as an indication of the Company's performance or to
cash flows as a measure of liquidity. Funds from operations presented herein is
not necessarily comparable to funds from operations presented by other real
estate companies due to the fact that not all real estate companies use the same
definition. However, the Company's funds from operations is comparable to the
funds from operations of real estate companies that use the current definition
of the National Association of Real Estate Investment Trusts ("NAREIT"), after
the adjustment for straight-lining of rents and non-recurring charges.

INFLATION

The Company's leases with the majority of its tenants provide for recoveries and
escalation charges based upon the tenant's proportionate share of, and/or
increases in, real estate taxes and certain operating costs, which reduce the
Company's exposure to increases in operating costs resulting from inflation.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

The Company considers portions of this information to be forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. Such forward-looking
statements relate to, without limitation, the Company's future economic
performance, plans and objectives for future operations and projections of
revenue and other financial items. Forward-looking statements can be identified
by the use of words such as "may," "will," "should," "expect," "anticipate,"
"estimate" or "continue" or comparable terminology. Forward-looking statements
are inherently subject to risks and uncertainties, many of which the Company
cannot predict with accuracy and some of which the Company might not even
anticipate. Although the Company believes that the expectations reflected in
such forward-looking statements are based upon reasonable assumptions, it can
give no assurance that its expectations will be achieved. Future events and
actual results, financial and otherwise, may differ materially from the results
discussed in the forward-looking statements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the exposure to loss resulting from changes in interest rates,
foreign currency exchange rates, commodity prices and equity prices. In pursuing
its business plan, the primary market risk to which the Company is exposed is
interest rate risk. Changes in the general level of interest rates prevailing in
the financial markets may affect the spread between the Company's yield on
invested assets and cost of funds and, in turn, our ability to make
distributions or payments to our investors.

Approximately $1.6 billion of the Company's long-term debt bears interest at
fixed rates and therefore the fair value of these instruments is affected by
changes in market interest rates. The following table presents principal cash
flows (in thousands) based upon maturity dates of the debt obligations and the
related weighted-average interest rates by expected maturity dates for the fixed
rate debt. The interest rate on the variable rate debt as of June 30, 2001
ranged from LIBOR plus 65 basis points to LIBOR plus 80 basis points.

While the Company has not experienced any significant credit losses, in the
event of a significant rising interest rate environment and/or economic
downturn, defaults could increase and result in losses to the Company which
adversely affect its operating results and liquidity.
