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
September 30, 2001, the Company owned or had interests in 269 properties, plus
developable land (collectively, the "Properties"). The Properties aggregate
approximately 28.7 million square feet, and are comprised of 162 office
buildings and 95 office/flex buildings totaling approximately 28.3 million
square feet (which includes eight office buildings and one office/flex building
aggregating 1.5 million square feet, owned by unconsolidated joint ventures in
which the Company has investment interests), nine 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 10 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.

                        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:

                        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 estimated 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 $1,180 and
                        $1,055 for the three months ended September 30, 2001 and
                        2000, respectively, and $3,462 and $2,857 for the nine
                        months ended September 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 $899 and $794 for the three months ended
                        September 30, 2001 and 2000, respectively, and $2,501
                        and $2,383 for the nine months ended September 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.

                        common unit, as well as the third quarter preferred unit
                        distribution of $17.8932 per preferred unit, were
                        approved by the Board of Directors on September 20, 2001
                        and paid on October 22, 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.

8. SENIOR UNSECURED NOTES

On January 29, 2001, the Operating Partnership issued $300,000 face amount of
7.75 percent senior unsecured notes with interest payable semi-annually in
arrears. The total proceeds from the issuance (net of selling commissions and
discount) of approximately $296,300 were used primarily to pay down outstanding
borrowings under the 2000 Unsecured Facility, as defined in Note 9. The senior
unsecured notes were issued at a discount of approximately $1,731, which is
being amortized over the term as an adjustment to interest expense.

The Operating Partnership's senior unsecured notes are redeemable at any time at
the option of the Company, subject to certain conditions including yield
maintenance.

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") (one-month
LIBOR: 2.63 percent at September 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

                                       20
<Page>

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 rate and facility fee will be adjusted 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 and was repaid in full and
terminated at maturity on June 29, 2001.

SUMMARY
As of September 30, 2001 and December 31, 2000, the Company had outstanding
borrowings of $73,000 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.

for 2001. Total expense recognized by the Company for both the nine month
periods ended September 30, 2001 and 2000 was $300.

OTHER
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.

2000 Employee Plan and Employee Plan subsequent to 1995 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 options were granted at
the fair market value at the dates of grant and have terms of ten years. There

</Table>

Base rents for the Same-Store Properties increased $1.4 million, or 1.1 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
$0.1 million, or 0.3 percent, for 2001 over 2000, due to the recovery of a
decreased amount of total property expenses in 2001. Parking and other income
for the Same-Store Properties decreased $0.8 million, or 22.9 percent, due
primarily to decreased third party management fees in 2001.

Real estate taxes on the Same-Store Properties decreased $0.1 million, or 0.4
percent, for 2001 as compared to 2000, due primarily to lower assessments on
certain properties in 2001. Utilities for the Same-Store Properties increased
$0.1 million, or 0.4 percent, for 2001 as compared to 2000, due primarily to
increased electric rates. Operating services for the Same-Store Properties
decreased $0.3 million, or 1.6 percent, due primarily to a decrease in repair
costs in 2001.

Equity in earnings of unconsolidated joint ventures decreased $0.3 million, or
14.1 percent, for 2001 as compared to 2000. This is due primarily to the sale of
two joint venture office properties in 2001 (see Note 4 to the Financial
Statements).

Interest income increased $0.4 million, or 135.4 percent, for 2001 as compared
to 2000. This increase was due primarily to the effect of net proceeds from
certain property sales being invested in cash and cash equivalents for the
period of time prior to which such proceeds were reinvested.

General and administrative increased by $3.3 million, or 60.5 percent, for 2001
as compared to 2000. This increase is due primarily to bad debt expense of
approximately $2.5 million in 2001, related to a lease breakage fee receivable
from a former tenant deemed uncollectible, 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 $0.8 million, or 3.4 percent, for
2001 over 2000. Of this decrease, $1.5 million, or 6.3 percent, is attributable
to the Same-Store Properties, and $0.5 million, or 2.1 percent, is due to the
Dispositions, partially offset by an increase of $1.2 million, or 5.0 percent,
due to the Acquired Properties.


                                       30
<Page>

Interest expense increased $1.9 million, or 7.4 percent, for 2001 as compared to
2000. This increase is due primarily to higher average outstanding debt balances
in 2001 versus 2000, primarily as a result of Common Stock repurchases in late
2000 and early 2001 and, to a lesser extent, the replacement in early 2001 of
short-term credit facility borrowings with long-term, higher, fixed rate debt.

The Company incurred non-recurring charges of $27.9 million in 2000, as a result
of costs associated with the termination of the Prentiss merger agreement (see
Note 3 to the Financial Statements).

Income before realized gains and unrealized losses on disposition of rental
property and minority interests increased to $43.0 million in 2001 from $16.6
million in 2000. The increase of approximately $26.4 million is due to the
factors discussed above.

Net income increased by $4.0 million, from $20.0 million in 2000 to $24.0
million in 2001. This increase was a result of an increase in income before
realized gains and unrealized losses on disposition of rental property and
minority interests of $26.4 million, which was partially offset by an unrealized
loss on disposition of rental property in 2001 of $11.6 million, a gain on sale
of rental property in 2000 of $10.0 million, and a decrease in minority
interests of $0.8 million in 2001.

</Table>

Base rents for the Same-Store Properties increased $10.4 million, or 2.8
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 $2.0 million, or 4.4 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 $4.5 million, or 34.9 percent, due primarily to fewer lease
termination fees in 2001.

Real estate taxes on the Same-Store Properties increased $0.4 million, or 0.9
percent, for 2001 as compared to 2000, due primarily to property tax rate
increases in certain municipalities in 2001, partially offset by lower
assessments on certain properties in 2001. Utilities for the Same-Store
Properties increased $1.9 million, or 5.9 percent, for 2001 as compared to 2000,
due primarily to increased gas rates. Operating services for the Same-Store
Properties increased $0.7 million, or 1.4 percent, due primarily to an increase
in maintenance costs in 2001.

Equity in earnings of unconsolidated joint ventures increased $2.9 million, or
66.6 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, partially offset by the sale of a joint
venture office property in 2001 (see Note 4 to the Financial Statements).

Interest income decreased $0.8 million, or 30.2 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 for
longer periods of time.

General and administrative increased by $4.9 million, or 29.3 percent, for 2001
as compared to 2000. This increase is due primarily to increased, bad debt
expense of approximately $2.5 million in 2001, related to a lease breakage fee
receivable due from a former tenant deemed uncollectible, 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 $0.5 million, or 0.7 percent, for
2001 over 2000. Of this decrease, $2.2 million, or 3.3 percent, is due to the
Same-Store Properties and $2.1 million, or 3.0 percent, attributable to the
Dispositions, partially offset by an increase of $3.8 million, or 5.6 percent,
due to the Acquired Properties.


                                       32

Interest expense increased $5.7 million, or 7.0 percent, for 2001 as compared to
2000. This increase is due primarily to higher average outstanding debt balances
in 2001 versus 2000, primarily as a result of Common Stock repurchases in late
2000 and early 2001 and, to a lesser extent, the replacement in early 2001 of
short-term credit facility borrowings with long-term, higher, fixed rate debt.

Non-recurring charges of $37.1 million were incurred in 2000, as a result of
costs associated with the termination of the Prentiss merger agreement (see Note
3 to the Financial Statements) in September 2000 and costs associated with the
resignations of Brant Cali and John R. Cali (see Note 13 to Financial
Statements) in June 2000.

Income before realized gains and unrealized losses on disposition of rental
property and minority interests increased to $133.7 million in 2001 from $102.2
million in 2000. The increase of approximately $31.5 million is due to the
factors discussed above.

Net income decreased by $52.5 million, from $150.9 million in 2000 to $98.4
million in 2001. This decrease was a result of a gain on sale of rental property
of $86.2 million in 2000 and unrealized losses on disposition of rental property
of $9.7 million in 2001. This was partially offset by an increase in income
before realized gains and unrealized losses on disposition of rental property
and minority interests of $31.5 million, and a decrease in minority interests of
$11.9 million in 2001.

LIQUIDITY AND CAPITAL RESOURCES

STATEMENT OF CASH FLOWS During the nine months ended September 30, 2001, the
Company generated $188.1 million in cash flows from operating activities, and
together with $695.6 million in borrowings from the Company's senior
unsecured notes, revolving credit facilities and additional mortgage
financing, $124.1 million in proceeds from sales of rental property, $37.5
million in distributions received from unconsolidated joint ventures, $6.0
million in proceeds from repayment of a mortgage note receivable and $4.0
million in proceeds from stock options exercised used an aggregate of
approximately $1.1 billion to acquire properties and land parcels and pay for
other tenant and building improvements totaling $189.9 million, repay
outstanding borrowings on its revolving credit facilities and other mortgage
debt of $610.1 million, pay quarterly dividends and distributions of $130.0
million, invest $64.2 million in unconsolidated joint ventures, pay financing
costs of $3.3 million, repurchase 915,300 shares of its outstanding common
stock for $25.0 million, add $1.0 million to restricted cash and add $31.8
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, which is approximately 40 percent leased. 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 primarily through drawing on its revolving credit facility.


                                       33

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 October
31, 2001, the Company purchased for constructive retirement 2.9 million shares
of its outstanding common stock for an aggregate cost of approximately $80.5
million under the Repurchase Program. The Company has authorization to
repurchase up to an additional $69.5 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 September 30, 2001, the Company's total indebtedness of $1.7 billion
(weighted average interest rate of 7.19 percent) was comprised of $105.2 million
of revolving credit facility borrowings and other variable rate mortgage debt
(weighted average rate of 4.27 percent) and fixed rate debt of $1.6 billion
(weighted average rate of 7.39 percent).

As of September 30, 2001, the Company had outstanding borrowings of $73.0
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 2 and 3 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 2 and 3 of $162.9 million at September 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 September 30, 2001, the Company had 236 unencumbered properties, totaling
21.0 million square feet, representing 77.3 percent of the Company's total
portfolio on a square footage basis.

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 frequently examines 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 September 30, 2001, the Company classified 42 properties with an aggregate
net book value of $422.7 million as held for sale. The Company is currently in
various stages of contract negotiations for the sale of certain of the
properties. Substantially all of the properties are unencumbered. The sale of
one or more of these assets will enhance the company's short-term liquidity
although there is no assurance when and if any sales will occur or, if they
occur, how much proceeds the Company will realize.

As of September 30, 2001, the Company's total debt had a weighted average term
to maturity of approximately 5.1 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.

Funds from operations for the three and nine month periods ended September 30,
2001 and 2000, as calculated in accordance with NAREIT's definition as published
in October 1999, after adjustment for straight-lining of rents and non-recurring
charges, are summarized in the following table (IN THOUSANDS):

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 September 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.
