      conjunction with the rules and regulations of the Securities and Exchange
      Commission ("SEC"). Accordingly, they do not include all of the

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, 1999, the Company owned or had interests in 254 properties plus
developable land (collectively, the "Properties"). The Properties aggregate
approximately 28.1 million square feet, and are comprised of 160 office
buildings and 81 office/flex buildings totaling approximately 27.7 million
square feet (which included four office buildings and one office/flex building,
aggregating 1.0 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, two multi-family residential
complexes consisting of 453 units, two stand-alone retail properties and three
land leases. The Properties are located in 12 states, primarily in the
Northeast, plus the District of Columbia.

Basis of Presentation

The accompanying consolidated financial statements include all accounts of the
Company and its majority-owned subsidiaries, which consist principally of
Mack-Cali Realty, L.P. (the "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 construction. 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:

                  Leasehold interests                      Remaining lease term
                  --------------------------------------------------------------
                  Buildings and improvements                      5 to 40 years
                  --------------------------------------------------------------
                  Tenant improvements                The shorter of the term of
                                               the related lease or useful life
                  --------------------------------------------------------------
                  Furniture, fixtures and equipment               5 to 10 years
                  --------------------------------------------------------------

                  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.


                                       8


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 (loss) 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 (loss) of
                  unconsolidated joint ventures over 40 years. See Note 4.

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 $917 and $400 for the three months
                  ended June 30, 1999 and 1998, respectively, and $1,518 and
                  $654 for the six months ended June 30, 1999 and 1998,
                  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 Operating Partnership provide leasing services to the
                  Properties and receive compensation based on space leased. The
                  portion of such compensation which is capitalized and
                  amortized, approximated $743 and $659 for the three months
                  ended June 30, 1999 and 1998, respectively, and $1,401 and
                  $1,236 for the six months ended June 30, 1999 and 1998,
                  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 revenue includes income from parking
                  spaces leased to tenants. 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 13.

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 federal income tax to the extent it
                  distributes at least 95 percent of its REIT taxable income to
                  its shareholders and satisfies certain other requirements.
                  REITs are subject to a number of organizational and
                  operational requirements. 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.

Interest Rate
Contracts         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.


                                       9


                  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, 1999
                  represents dividends payable to shareholders of record on July

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 for the Company's stock option plans.
                  See Note 14.

Extraordinary
Item              Extraordinary item represents the effect resulting from the
                  early settlement of certain debt obligations, including
                  related deferred financing costs, prepayment penalties, yield
                  maintenance payments and other related items.

Non-Recurring
Charges           The Company considers non-recurring charges as costs incurred
                  specific to significant non-recurring events that impact the
                  comparative measurement of the Company's performance.

7. SENIOR UNSECURED NOTES

On March 16, 1999, the Operating Partnership issued $600,000 of senior unsecured
notes ("Senior Unsecured Notes") under a shelf registration statement which was
declared effective by the SEC in September 1998. Interest on the Senior
Unsecured Notes is payable semi-annually in arrears. The Senior Unsecured Notes
are redeemable at any time at the option of the Company, subject to certain
conditions including yield maintenance. The total proceeds from the issuance
(net of selling commissions and discount) of approximately $593,500 were used to
pay down outstanding borrowings under the 1998 Unsecured Facility, as defined
below, and to pay off certain mortgage loans. The Senior Unsecured Notes were
issued at a discount of approximately $2,748, which is being amortized over the
terms of the respective tranches as an adjustment to interest expense. Including
amortization of offering costs, the weighted average effective annual interest
rate for the Senior Unsecured Notes is approximately 7.38 percent.

A summary of the terms of the Senior Unsecured Notes outstanding as of June 30,
1999 is presented below:

                                                                       Effective

   Total Senior Unsecured Notes                              $597,344     7.38%
================================================================================

(1)   Includes the cost of terminated treasury lock agreements, offering and
      transaction costs and the discount on the notes.

In August 1999, the Operating Partnership issued an additional $185,283 of
unsecured corporate debt with an interest rate of 7.18 percent payable monthly
and maturity date of December 31, 2003. The Company used the proceeds to retire
the TIAA Mortgage as defined below (see Note 9).

The terms of the Senior Unsecured Notes and the unsecured corporate 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.

8. REVOLVING CREDIT FACILITIES

ORIGINAL UNSECURED FACILITY

The Original Unsecured Facility ("Original Unsecured Facility") was repaid in
full and retired in connection with the Company obtaining the 1998 Unsecured
Facility in April 1998, as defined below. On account of prepayment fees, loan
origination fees, legal fees, and other costs incurred in the retirement of the
Original Unsecured Facility, an extraordinary loss of $2,203, net of minority
interest's share of the loss ($275), was recorded for the year ended December
31, 1998.


                                       17



1998 UNSECURED FACILITY

In April 1998, the Company repaid in full and terminated the Original Unsecured
Facility and obtained a new unsecured revolving credit facility ("1998 Unsecured
Facility") with a current borrowing capacity of $1,000,000 from a group of 28
lenders. The interest rate is based on the Company's achievement of investment
grade unsecured debt ratings and is currently 90 basis points over London
Inter-Bank Offered Rate ("LIBOR") (5.05 percent at June 30, 1999). The 1998
Unsecured Facility matures in April 2001.

The terms of the 1998 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 for such period, subject to certain other adjustments. The
1998 Unsecured Facility also requires a 17.5 basis point fee on the unused
balance payable quarterly in arrears.

PRUDENTIAL FACILITY

The Company has a revolving credit facility ("Prudential Facility") from
Prudential Securities Corp. ("PSC") in the amount of $100,000, which currently
bears interest at 110 basis points over one-month LIBOR, with a maturity date of
June 30, 2000. The Prudential Facility is a recourse liability of the Operating
Partnership and is secured by the Company's equity interest in Harborside. The
Prudential Facility limits 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 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 for the preceding fiscal quarter for not more than three consecutive
quarters. In addition to the foregoing, the Prudential Facility limits 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.

SUMMARY

As of June 30, 1999, the Company had outstanding borrowings of $148,600 under
its revolving credit facilities (with aggregate borrowing capacity of
$1,100,000). The outstanding borrowings were comprised of $148,600 from the 1998
Unsecured Facility, with no outstanding borrowings on its Prudential Facility.

PORTFOLIO MORTGAGES

TIAA Mortgage

The Company has a $185,283 non-recourse mortgage loan with Teachers Insurance
and Annuity Association of America, with interest only payable monthly at a
fixed annual rate of 7.18 percent ("TIAA Mortgage"). The TIAA Mortgage is
secured and cross collateralized by 43 properties and matures in December 2003.
The Company has the option to convert, without any yield maintenance obligation
or prepayment premium, the TIAA Mortgage to unsecured public debt as a result of
the achievement of an investment grade credit rating. The TIAA Mortgage is
prepayable in whole or in part subject to certain provisions, including yield
maintenance.


                                       18


Using the proceeds from the issuance of $185,283 of unsecured corporate debt in
August 1999 (see Note 7), the Company repaid in full and retired the TIAA
Mortgage.

$150,000 Prudential Mortgage Loan

On April 30, 1998, the Company obtained a $150,000, interest-only, non-recourse
mortgage loan from Prudential ("$150,000 Prudential Mortgage Loan"). The loan,
which is secured by 12 properties, has an effective annual interest rate of 7.10
percent and a seven-year term. The Company has the option to convert the
mortgage loan to unsecured debt as a result of the achievement of an investment
grade credit rating. The mortgage loan is prepayable in whole or in part subject
to certain provisions, including yield maintenance.

Certain mortgages and loans payable were repaid and retired in connection with
the Company obtaining the $150,000 Prudential Mortgage Loan. On account of
prepayment fees, loan origination fees, legal fees, and other costs incurred in
the retirement of certain mortgages and loans payable in April 1998, an
extraordinary loss of $170, net of minority interest's share of the loss ($22),
was recorded in the year ended December 31, 1998.

(1)   As part of the Harborside acquisition in November 1996, the Company agreed
      to make payments (with an estimated net present value of approximately
      $5,252 at acquisition date) to the seller for development rights
      ("Contingent Obligation") if and when the Company commences construction
      on the acquired site during the next several years. However, the agreement
      provides, among other things, that even if the Company does not commence
      construction, the seller may nevertheless require the Company to acquire
      these rights during the six-month period after the end of the sixth year.
      After such period, the seller's option lapses, but any development in
      years 7 through 30 will require a payment, on an increasing scale, for the
      development rights. The Company is currently in the pre-development phase
      of a long-range plan to develop the Harborside site on a multi-property,
      multi-use basis.

INTEREST RATE CONTRACTS

On May 24, 1995, the Company entered into an interest rate swap agreement with a
commercial bank. The swap agreement fixes the Company's one-month LIBOR base to
6.285 percent per annum on a notional amount of $24,000. The swap agreement
expires on August 15, 1999.

On January 23, 1996, the Company entered into an interest rate swap agreement
with a commercial bank. The swap agreement fixed the Company's one-month LIBOR
base to 5.265 percent per annum on a notional amount of $26,000. The swap
agreement expired in January 1999.

On October 1, 1998, the Company entered into a forward treasury rate lock
agreement with a commercial bank. The agreement locked an interest rate of 4.089
percent per annum for the three-year U.S. Treasury Note effective November 4,
1999, on a notional amount of $50,000. The agreement will be used to fix the
Index Rate on $50,000 of the Harborside- Plaza I mortgage, for which the
Company's interest rate re-sets for three years beginning November 4, 1999 to
the three-year U.S. Treasury Note plus 110 basis points (see "Property
Mortgages: Harborside-Plaza I").

In connection with the issuance of the Senior Unsecured Notes, the Company
entered into and settled forward treasury rate lock agreements in March 1999.
These agreements were settled at a cost of approximately $517, which is being
amortized to interest expense over the terms of the respective tranches.

The Company is exposed to credit loss in the event of non-performance by the
other parties to the interest rate contracts. However, the Company does not
anticipate non-performance by any of the counterparties. The Company is also
exposed to market risk from the movement in interest rates pertaining to the
forward treasury rate lock agreement.

                                       20


PREFERRED UNITS

In connection with the Mack Transaction in December 1997, the Company issued
15,237 Series A Preferred Units and 215,325 Series B Preferred Units, with an
aggregate value of $236,491. The Preferred Units have a stated value of $1,000
per unit and are preferred as to assets over any class of common units or other
class of preferred units of the Company, based on circumstances per the
applicable unit certificates.

The quarterly distribution on each Preferred Unit (representing 6.75 percent of
the Preferred Unit stated value of $1,000 on an annualized basis) is an amount
equal to the greater of (i) $16.875 or (ii) the quarterly distribution
attributable to a Preferred Unit determined as if such unit had been converted
into common units, subject to adjustment for customary anti-dilution rights.
Each of the Series A Preferred Units may be converted at any time into common
units at a conversion price of $34.65 per unit, and, after the one year
anniversary of the date of the Series A Preferred Units' initial issuance,
common units received pursuant to such conversion may be redeemed into common
stock. Each of the Series B Preferred Units may be converted at any time into
common units at a conversion price of $34.65 per unit, and, after the three year
anniversary of the date of the Series B Preferred Units' initial issuance,
common units received pursuant to such conversion may be redeemed into common
stock. Each of the common units are redeemable for an equal number of shares of
common stock.

During 1998, the Company issued 19,694 additional Preferred Units (11,895 of
Series A and 7,799 of Series B), convertible into 568,369 common units and
valued at approximately $20,200, in connection with the achievement of certain
performance goals at the Mack Properties in redemption of an equivalent number
of contingent Preferred Units.

During the six months ended June 30, 1999, 20,952 Series A Preferred Units were
converted into 604,675 common units.

As of June 30, 1999, there was 229,304 Preferred Units outstanding (convertible
into 6,617,721 common units).

COMMON UNITS

Certain individuals and entities own common units in the Operating Partnership.
A common unit and a share of common stock of the Company have substantially the
same economic characteristics in as much as they effectively share equally in
the net income or loss of the Operating Partnership.

Common units are redeemable by the common unitholders at their option, subject
to certain restrictions, on the basis of one common unit for either one share of
common stock or cash equal to the fair market value of a share at the time of
the redemption. The Company has the option to deliver shares of common stock in
exchange for all or any portion of the cash requested. When a unitholder redeems
a common unit, minority interest is reduced and the Company's investment in the
Operating Partnership is increased.

During 1998, the Operating Partnership redeemed a total of 82,880 common units
in exchange for an aggregate of $3,163 in cash. Additionally, the Operating
Partnership redeemed an aggregate of 29,300 common units for an equivalent
number of shares of common stock in the Company.

On March 26, 1998, in connection with the Pacifica portfolio-phase I
acquisition, the Company issued 100,175 common units, valued at approximately
$3,779.

On April 30, 1998, in connection with the acquisition of a 49.9 percent interest
in the G&G Martco joint venture (see Note 4), the Company issued 218,105 common
units, valued at approximately $8,334.

On June 8, 1998, in connection with the Pacifica portfolio-phase II acquisition,
the Company issued 585,263 common units, valued at approximately $20,753.

On July 20, 1998, in connection with the expansion of one of the Mack
Properties, the Company issued 52,245 common units, valued at approximately
$1,632.

On September 10, 1998, in connection with the acquisition of 40 Richards Avenue,
the Company issued 414,114 common units, valued at approximately $12,615.


                                       21


During 1998, the Company also issued 1,731,386 common units, valued at
approximately $58,936, in connection with the achievement of certain performance
goals at the Mack Properties in redemption of an equivalent number of contingent
common units.

On June 4, 1999, in connection with the acquisition of a 0.1 percent interest in
G&G Martco joint venture (see Note 4), the Company issued 437 common units,
valued at approximately $17.

During the six months ended June 30, 1999, the Operating Partnership redeemed an
aggregate of 1,634,164 common units for an equivalent number of shares of common
stock in the Company.

During the six months ended June 30, 1999, the Company also issued 242,157
common units, valued at approximately $7,241, in connection with the achievement
of certain performance goals at the Mack Properties in redemption of an
equivalent number of contingent common units.

As of June 30, 1999, there were 8,299,690 common units outstanding.

CONTINGENT COMMON & PREFERRED UNITS

In connection with the Mack Transaction in December 1997, 2,006,432 contingent
common units, 11,895 Series A contingent Preferred Units and 7,799 Series B
contingent Preferred Units were issued as contingent non-participating units
("Contingent Units"). Such Contingent Units have no voting, distribution or
other rights until such time as they are redeemed into common units, Series A
Preferred Units, and Series B Preferred Units, respectively. Redemption of such
Contingent Units shall occur upon the achievement of certain performance goals
relating to certain of the Mack Properties, specifically the achievement of
certain leasing activity. When Contingent Units are redeemed for common and
Preferred Units, an adjustment to the purchase price of certain of the Mack
Properties is recorded, based on the value of the units issued.

On account of certain of the performance goals at the Mack Properties having
been achieved during 1998, the Company redeemed 1,731,386 contingent common
units and 19,694 contingent Preferred Units and issued an equivalent number of
common and Preferred Units, as indicated above.

On account of certain of the performance goals at the Mack Properties having
been achieved during the six months ended June 30, 1999, the Company redeemed
242,157 contingent common units and issued an equivalent number of common units,
as indicated above. There were no contingent Preferred Units outstanding and
32,889 contingent common units outstanding as of June 30, 1999.

exercisable at $37.80 per common unit and expire on December 11, 2002.

MINORITY INTEREST OWNERSHIP

As of June 30, 1999 and December 31, 1998, the minority interest common
unitholders owned 12.3 percent (20.2 percent, including the effect of the
conversion of Preferred Units into common units) and 13.7 percent (22.2 percent
including the effect of the conversion of Preferred Units into common units) of
the Operating Partnership, respectively (excluding any effect for the exercise
of Unit Warrants).

11. EMPLOYEE BENEFIT PLAN

All employees of the Company who meet certain minimum age and period of service
requirements are eligible to participate in a 401(k) defined contribution plan
(the "401(k) Plan"). The 401(k) Plan allows eligible employees to defer up to 15
percent of their annual compensation. The amounts contributed by employees are
immediately vested and non-forfeitable. The Company, at management's discretion,
may match employee contributions, although no employer contributions have been
made to date.

OTHER

On April 19, 1999, the Company announced the following changes in the membership
of its Board of Directors and the identities, titles and responsibilities of its
executive officers: (i) Thomas A. Rizk resigned from the Board of Directors, the
Executive Committee of the Board of Directors, his position as Chief Executive
Officer and as an employee of the Company; (ii) Mitchell E. Hersh was appointed
Chief Executive Officer of the Company simultaneous with his resignation from
his positions as President and Chief Operating Officer of the Company; (iii)
Timothy M. Jones was appointed President of the Company simultaneous with his
resignation from his positions as Executive Vice President and Chief Investment
Officer of the Company; and (iv) Brant Cali was appointed to the Board of
Directors of the Company to fill the remainder of Thomas A. Rizk's term as a
Class III Director and was appointed Chief Operating Officer of the Company,
also remaining as an Executive Vice President and Assistant Secretary of the
Company.

Pursuant to the terms of Mr. Rizk's employment agreement entered into with the
Company in December 1997 and an agreement entered into simultaneous with his
resigning from the Company, Mr. Rizk received a payment of approximately $14,490
in April 1999 and will receive $500 annually over the next three years. All
costs associated with Mr. Rizk's resignation are included in non-recurring
charges for the three and six month periods ended June 30, 1999.

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.

13. TENANT LEASES

The Properties are leased to tenants under operating leases with various
expiration dates through 2016. Substantially all of the leases provide for

14. 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.

could be made from time to time in open market transactions at prevailing prices
or through privately negotiated transactions.

For the year ended December 31, 1998, the Company purchased, for constructive
retirement, 854,700 shares of its outstanding common stock for an aggregate cost

DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN

The Company filed a registration statement with the SEC for the Company's
dividend reinvestment and stock purchase plan ("Plan") which was declared
effective in February 1999. The Plan commenced on March 1, 1999.

During the six months ended June 30, 1999, 320 shares were issued and proceeds
of approximately $10 were received from stock purchases and/or dividend
reinvestments under the Plan.


                                       24


SHAREHOLDER RIGHTS PLAN

On June 10, 1999, the Board of Directors of the Company authorized a dividend
distribution of one preferred share purchase right ("Right") for each
outstanding share of common stock to be distributed to all holders of record of
the common stock on July 6, 1999. Each Right entitles the registered holder to
purchase from the Company one one-thousandth of a share of Series A junior
participating preferred stock, par value $0.01 per share ("the Preferred
Shares"), at a price of $100.00 per one one-thousandth of a Preferred Share
("Purchase Price"), subject to adjustment as provided in the rights agreement.
The Rights expire on July 6, 2009, unless the expiration date is extended or the
Right is redeemed or exchanged earlier by the Company.

The Rights will be attached to each share of common stock. The Rights will
generally be exercisable only if a person or group becomes the beneficial owner
of 15 percent or more of the outstanding common stock or announces a tender
offer for 15 percent or more of the outstanding common stock ("Acquiring
Person"). In the event that a person or group becomes an Acquiring Person, each
holder of a Right will have the right to receive, upon exercise, common stock
having a market value equal to two times the Purchase Price of the Right.

STOCK OPTION PLANS

In 1994, and as subsequently amended, the Company established the Mack-Cali
Employee Stock Option Plan ("Employee Plan") and the Mack-Cali Director Stock
Option Plan ("Director Plan") under which a total of 5,380,188 shares (subject
to adjustment) of the Company's common stock have been reserved for issuance
(4,980,188 shares under the Employee Plan and 400,000 shares under the Director
Plan). Stock options granted under the Employee Plan in 1994 and 1995 become
exercisable over a three-year period and those options granted under the
Employee Plan in 1996, 1997 and 1998 become exercisable over a five-year period.
All stock options granted under the 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. As of June 30, 1999 and December 31, 1998, the
stock options outstanding had a weighted average remaining contractual life of
approximately 7.6 and 8.5 years, respectively.

                                       25


As of June 30, 1999 and December 31, 1998, there were 914,976 Stock Warrants
outstanding. As of June 30, 1999 and December 31, 1998, there were 585,989 and

EXECUTIVE STOCK COMPENSATION

Effective July 1, 1999, the Company entered into amended and restated employment
contracts with six of its key executive officers which provided for, among other
things, compensation in the form of stock awards ("Restricted Stock Awards") and
associated tax obligation payments. In connection with the Restricted Stock
Awards, the executive officers are to receive up to a total of 193,593 shares of
the Company's common stock vesting over a five-year period contingent upon the
Company meeting certain performance and/or stock price appreciation objectives.

DEFERRED STOCK COMPENSATION PLAN FOR DIRECTORS

The Deferred Compensation Plan for Directors ("Deferred Compensation Plan")
commenced January 1, 1999 and is a plan which allows non-employee directors of
the Company to elect to defer up to 100 percent of their annual retainer fee
into deferred stock units. The deferred stock units are convertible into an
equal number of shares of common stock upon the directors' termination of
service from the Board of Directors or a change in control of the Company, as
defined in the plan. Deferred stock units are credited to each director
quarterly using the closing price of the Company's common stock on the
applicable dividend record date for the respective quarter. Each participating
director's account is also credited for an equivalent amount of deferred stock
units based on the dividend rate for each quarter.

During the six months ended June 30, 1999, 1,309 deferred stock units were
earned.

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, 1999 and 1998 in accordance with FASB No. 128.

constructive retirement, 854,700 shares of its outstanding common stock for
approximately $25,058. Additionally, during the six months ended June 30, 1999,

16. IMPACT OF RECENTLY-ISSUED ACCOUNTING STANDARDS

In April 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued Statement of Position 98-5,
"Reporting on the Cost of Start-Up Activities" ("SOP 98-5"), which is effective
for fiscal years beginning after December 15, 1998. SOP 98-5 requires costs of
start-up and organizational activities be expensed as incurred. The adoption of
SOP 98-5 did not have a material effect on the Company's financial statements.

In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, Accounting for Derivative Instruments and Hedging Activities ("FASB No.
133"). FASB No. 133 is effective for all fiscal quarters of all fiscal years
beginning after June 15, 1999. In June 1999, the FASB delayed the implementation
date of FASB No. 133 by one year (January 1, 2001 for the Company). FASB No. 133
requires that all derivative instruments be recorded on the balance sheet at
their fair value. Changes in the fair value of derivatives are recorded each
period in current earnings or other comprehensive income, depending on whether a
derivative is designated as part of a hedge transaction and, if it is, the type
of hedge transaction. Management of the Company anticipates that, due to its
limited use of derivative instruments, the adoption of FASB No. 133 will not
have a significant effect on the Company's results of operations or its
financial position.

17. PRO FORMA FINANCIAL INFORMATION

The following pro forma financial information for the six months ended June 30,
1999 and 1998 are presented as if all acquisitions and common stock offerings
completed during the six months ended June 30, 1999 and the year ended December
31, 1998 had occurred on January 1, 1998. In management's opinion, all
adjustments necessary to reflect the effects of these transactions have been
made.

This pro forma financial information is not necessarily indicative of what the
actual results of operations of the Company would have been assuming such
transactions had been completed as of January 1, 1998, nor do they represent the
results of operations of future periods.

OTHER DATA:
Number of wholly-owned properties                     249                    22                   227

Base rents for the Same-Store Properties increased $3.1 million, or 2.9 percent,
for 1999 as compared to 1998, due primarily to occupancy and rental rate
increases in 1999. Escalations and recoveries from tenants for the Same-Store
Properties increased $3.0 million, or 24.4 percent, for 1999 over 1998, due to
the recovery of an increased amount of total property expenses, as well as
additional settle-up billings in 1999. Parking and other income for the
Same-Store Properties increased $0.1 million, or 4.5 percent, due primarily to
lease termination fees received in 1999.

Real estate taxes on the Same-Store Properties increased $1.4 million, or 11.8
percent, for 1999 as compared to 1998, due primarily to property tax rate
increases in certain municipalities in 1999. Utilities for the Same-Store
Properties increased $0.1 million, or 0.8 percent, for 1999 as compared to 1998,
due primarily to increased usage in 1999. Operating services for the Same-Store
Properties increased $0.3 million, or 2.2 percent, due primarily to additional
maintenance costs incurred.

Equity in earnings of unconsolidated joint ventures increased $0.8 million in
1999 as compared to 1998. This is due to additional joint ventures being entered
into by the Company (see Note 4 to the Financial Statements).

Interest income decreased by approximately $0.7 million, or 76.5 percent, for
1999 as compared to 1998. This decrease was due primarily to repayment by a
borrower of a mortgage note receivable in 1998 with no interest income from
mortgage note receivables in 1999.

General and administrative decreased by $0.6 million, or 9.8 percent for 1999 as
compared to 1998. This decrease is due primarily to decreased payroll and
related costs in 1999.

Depreciation and amortization increased by $3.4 million, or 17.7 percent, for
1999 over 1998. Of this increase, $1.7 million or 8.8 percent, is attributable
to the Acquired Properties, and $1.7 million, or 8.9 percent, is due to the
Same-Store Properties.

Interest expense increased $3.9 million, or 18.0 percent, for 1999 as compared
to 1998. This increase is due primarily to the replacement in 1999 of short-term
credit facility borrowings with long-term fixed rate unsecured debt and net
additional drawings from the Company's revolving credit facilities generally as
a result of Company acquisitions in 1998. These increases were partially offset
by a reduction in LIBOR in 1999, the reduction in spread over LIBOR due to the
1998 Unsecured Facility signed in April 1998 and the achievement by the Company
of investment grade credit ratings in November 1998.

Non-recurring charges of $16.5 million were incurred in 1999, as a result of the
resignation of Thomas A. Rizk (see Note 12 to the Financial Statements).

Income before minority interest and extraordinary item decreased to $25.3
million in 1999 from $38.2 million in 1998. The decrease of $12.9 million is due
to the factors discussed above.


                                       31


Net income decreased by $9.3 million for 1999, from $28.0 million in 1998 to
$18.7 million in 1999. This decrease is a result of a decrease in income before
minority interest and extraordinary item of $12.9 million (as discussed above),
offset by an extraordinary item of $2.4 million (net of minority interest) in
1998 and a decrease of $1.2 million in minority interest.

for 1999 as compared to 1998, due primarily to occupancy and rental rate
increases in 1999. Escalations and recoveries from tenants for the Same-Store
Properties increased $3.8 million, or 16.6 percent, for 1999 over 1998, due to
the recovery of an increased amount of total property expenses, as well as
additional settle-up billings in 1999. Parking and other income for the
Same-Store Properties increased $0.7 million, or 14.8 percent, which is
primarily attributable to lease termination fees received in 1999.

Real estate taxes on the Same-Store Properties increased $1.9 million, or 8.7
percent, for 1999 as compared to 1998, due primarily to property tax rate
increases in certain municipalities in 1999. Utilities for the Same-Store
Properties decreased $0.2 million, or 1.1 percent, for 1999 as compared to 1998,
due primarily to decreased electric rates and usage in early 1999. Operating
services for the Same-Store Properties increased $0.8 million, or 2.9 percent,
due primarily to increased snow removal costs incurred at the Same-Store
Properties in 1999.

Equity in earnings of unconsolidated joint ventures increased $0.5 million in
1999 as compared to 1998. This is due to additional joint ventures being entered
into by the Company (see Note 4 to the Financial Statements).

Interest income decreased by approximately $1.0 million, or 67.8 percent, for
1999 as compared to 1998. This decrease was due primarily to repayment by a
borrower of a mortgage note receivable in 1998 with no interest income from
mortgage note receivables in 1999.

General and administrative increased by $1.3 million, or 10.4 percent for 1999
as compared to 1998. This increase is due primarily to an increase in payroll
and related costs and professional fees as a result of the Company's expansion
in 1998.

Depreciation and amortization increased by $9.1 million, or 25.8 percent, for
1999 over 1998. Of this increase, $6.8 million or 19.4 percent, is attributable
to the Acquired Properties, and $2.3 million, or 6.4 percent, is due to the
Same-Store Properties.

Interest expense increased $9.1 million, or 22.5 percent, for 1999 as compared
to 1998. This increase is due primarily to the replacement in 1999 of short-term
credit facility borrowings with long-term fixed rate unsecured debt and net
additional drawings from the Company's revolving credit facilities generally as
a result of Company acquisitions in 1998. These increases were partially offset
by a reduction in LIBOR in 1999, the reduction in spread over LIBOR due to the
1998 Unsecured Facility signed in April 1998 and the achievement by the Company
of investment grade credit ratings in November 1998.

Non-recurring charges of $16.5 million were incurred in 1999, as a result of the
resignation of Thomas A. Rizk (see Note 12 to the Financial Statements).


                                       33


Income before minority interest and extraordinary item decreased to $66.1
million in 1999 from $72.0 million in 1998. The decrease of $5.9 million is due
to the factors discussed above.

Net income decreased by $3.8 million for 1999, from $54.6 million in 1998 to
$50.8 million in 1999. This decrease is a result of a decrease in income before
minority interest and extraordinary item of $5.9 million (as discussed above),
and an increase of $0.3 million in minority interest, offset by an extraordinary
item of $2.4 million (net of minority interest) in 1998.

Liquidity and Capital Resources

Statement of Cash Flows

During the six months ended June 30, 1999, the Company generated $110.0 million
in cash flows from operating activities, and together with $773.6 million in
borrowings from the Company's revolving credit facilities, the issuance of
unsecured notes and funds from additional mortgage debt, $0.9 million in
proceeds from stock options exercised, $10.6 million in distributions received
from unconsolidated joint ventures, used an aggregate of approximately $895.1
million to acquire properties and land parcels and pay for other tenant and
building improvements totaling $71.1 million, repay outstanding borrowings on
its revolving credit facilities and other mortgage debt of $699.7 million, pay
quarterly dividends and distributions of $81.3 million, invest $29.9 million in
unconsolidated joint ventures, repurchase 26,000 shares of its outstanding
common stock for $0.7 million, pay deferred financing costs of $6.6 million, add
$0.1 million to restricted cash and increase the Company's cash and cash
equivalents by $5.7 million.

Capitalization

During the six months ended June 30, 1999, in conjunction with the redemption of
certain of the contingent units issued in the Mack Transaction, the Company
issued a total of 242,157 common units with a total value of approximately $7.2
million at time of issuance.

In August 1998, the Board of Directors of the Company authorized a share
repurchase program under which the Company was permitted to purchase up to
$100.0 million of the Company's outstanding common stock. Purchases could be
made from time to time in open market transactions at prevailing prices or
through privately negotiated transactions. Subsequently, through June 30, 1999,
the Company purchased, for constructive retirement, 880,700 shares of its
outstanding common stock for an aggregate cost of approximately $25.8 million.
Concurrent with these purchases, the Company sold to the Operating Partnership
880,700 common units for approximately $25.8 million.

On June 10, 1999, the Board of Directors of the Company authorized a dividend
distribution of one preferred share purchase right for each outstanding share of
common stock to be distributed to all holders of record of the common stock on
July 6, 1999. Each Right entitles the registered holder to purchase from the
Company one one-thousandth of a share of Series A junior participating preferred
stock, par value $0.01 per share, at a price of $100.00 per one one-thousandth
of a Preferred Share, subject to adjustment as provided in the rights agreement.
The Rights expire on July 6, 2009, unless the expiration date is extended or the
Right is redeemed or exchanged earlier by the Company.

The Rights will be attached to each share of common stock. The Rights will
generally be exercisable only if a person or group becomes the beneficial owner
of 15 percent or more of the outstanding common stock or announces a tender
offer for 15 percent or more of the outstanding common stock. In the event that
a person or group becomes an Acquiring Person, each holder of a Right will have
the right to receive, upon exercise, common stock having a market value equal to
two times the Purchase Price of the Right. The Company's adoption of the
shareholder rights plan was not taken in response to any known effort to acquire
control of the Company.

As of June 30, 1999, the Company's total indebtedness of $1.5 billion (weighted
average interest rate of 7.08 percent) was comprised of $228.8 million of
revolving credit facility borrowings and other variable rate mortgage debt
(average rate of 5.84 percent), fixed rate debt of $1.3 billion (average rate of
7.31 percent), and a Contingent Obligation of $6.4 million.

As of June 30, 1999, the Company had outstanding borrowings of $148.6 million
under its revolving credit facilities (with aggregate borrowing capacity of $1.1
billion). The total outstanding borrowings were from the 1998 Unsecured
Facility, with no outstanding borrowings on its Prudential Facility. The 1998
Unsecured Facility, with 28 lender banks, carries an interest rate of 90 basis
points over LIBOR and matures in April 2001. The Prudential Facility carries an
interest rate of 110 basis points over LIBOR and matures in June 2000.


                                       34


The terms of the 1998 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 for such period, subject to certain other adjustments. The
1998 Unsecured Facility also requires a 17.5 basis point fee on the unused
balance payable quarterly in arrears.

The Company has three investment grade credit ratings. Duff & Phelps Credit
Rating Co. ("DCR") and Standard & Poors Rating Services ("S&P") have each
assigned their BBB rating to the $785.3 million of total unsecured corporate
debt of the Operating Partnership. DCR and S&P 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 unsecured corporate debt
and its Ba1 rating to prospective preferred stock offerings of the Company.

The terms of the unsecured corporate 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.

In May 1995, the Company entered into an interest rate swap agreement with a
commercial bank. The swap agreement fixes the Company's one-month LIBOR base to
6.285 percent per annum on a notional amount of $24.0 million. The swap
agreement expires on August 15, 1999.

In October 1998, the Company entered into a forward treasury rate lock agreement
with a commercial bank. The agreement locked an interest rate of 4.089 percent
per annum for the three-year U.S. Treasury Note effective November 4, 1999, on a
notional amount of $50.0 million. The agreement will be used to fix the Index
Rate on $50.0 million of the Harborside - Plaza I mortgage, for which the
Company's interest rate re-sets for three years beginning November 4, 1999 to
the interpolated three-year U.S. Treasury Note plus 110 basis points (see Note 9
to the Financial Statements - "Property Mortgages: Harborside-Plaza I").

Using the proceeds from the issuance of $185.3 million of unsecured corporate
debt in August 1999, the Company repaid in full and retired the TIAA Mortgage,
which was secured by 43 properties aggregating 3.1 million square feet.
Following the repayment, the Company had 217 unencumbered properties, totaling
20.1 million square feet, representing 73.5 percent of the Company's total
portfolio on a square footage basis. The Company is currently reviewing its
option to convert the $150.0 Million Prudential Mortgage Loan, encumbering 12
properties aggregating 2.4 million square feet, to unsecured corporate debt.

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 $785.3 million of
unsecured corporate debt. The Company also has an effective registration
statement with the SEC for a dividend reinvestment and stock purchase plan,
which commenced on March 1, 1999.

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 credit facilities and other debt and equity financing.

The Company expects to meet its short-term liquidity requirements generally
through its working capital and net cash provided by operating activities, along
with the 1998 Unsecured Facility and the Prudential Facility. The Company is
frequently examining potential property acquisitions and construction projects
and, at any given time, one or more of such acquisitions may be under
consideration. Accordingly, the ability to fund property acquisitions is a major
part of the Company's financing


                                       35


requirements. The Company expects to meet its financing requirements through
funds generated from operating activities, long-term or short-term borrowings
(including draws on the Company's revolving credit facilities) and the issuance
of additional debt or equity securities. In addition, the Company anticipates
utilizing the 1998 Unsecured Facility and the Prudential Facility primarily to
fund property acquisitions.

As of quarter end, the Company's total debt had a weighted average term to
maturity of 5.9 years. The Company does not intend to reserve funds to retire
the unsecured corporate debt, Harborside mortgages, $150.0 Million Prudential
Mortgage Loan, its other property mortgages or other long-term 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 corporate debt, preferred stock,
and/or obtaining additional mortgage debt, some or all of which may be completed
during 1999. 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 95 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 $130.4 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.

SCHEDULE OF LEASE EXPIRATIONS

The following table sets forth a schedule of the lease expirations for the total
of the Company's wholly-owned office, office/flex, industrial/warehouse and
stand-alone retail properties beginning July 1, 1999, assuming that none of the
tenants exercises renewal options:

Funds from Operations

The Company considers funds from operations ("FFO"), after adjustment for
straight-lining of rents, 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 and
significant non-recurring items, and sales of 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.

NAREIT's definition of funds from operations indicates that the calculation
should be made before any extraordinary item (determined in accordance with
GAAP), and before any deduction of significant non-recurring events that
materially distort the comparative measurement of the Company's performance.

Funds from operations for the three and six month periods ended June 30, 1999
and 1998 as calculated in accordance with NAREIT's definition as published in
March 1995, after adjustment for straight-lining of rents, are summarized in the

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.

Disruption in Operations Due To Year 2000 Problems.

General

The Year 2000 issue is the result of computer programs and embedded chips using
a two-digit format, as opposed to four digits, to indicate the year. Such
computer systems may be unable to interpret dates beyond the year 1999, which
could cause a system failure or other computer errors, leading to disruptions in
operations. We have developed a three-phase Year 2000 project (the "Project") to
determine our Year 2000 systems compliance. Phase I was to identify those
systems with which we have exposure to Year 2000 issues. Phase II was the
development and implementation of action plans to be Year 2000 compliant in all
areas. Phase III is the final testing of each major area of exposure to assure
compliance. We have identified three major areas critical for successful Year
2000 compliance: (i) our central accounting and operating computer system at our
Cranford, New Jersey headquarters and local networks and related systems in our
regional offices, (ii) inquiries of our tenants and key vendors as to their Year
2000 readiness and (iii) assessment of our individual buildings as to the Year
2000 readiness of their operating systems. We believe that progress in all such
areas is proceeding on schedule and that we will experience no material adverse
effect as a result of the Year 2000 issue. There can, however, be no assurance
that this will be the case. Set forth below is a more detailed analysis of the
Project and its anticipated impact on us.

Central Accounting and Operating Systems

We have completed a review of key computer hardware and software and other
equipment, and have modified, upgraded or replaced all identified hardware and
equipment in our corporate and regional offices that we believe may be affected
by problems associated with Year 2000. Such hardware includes, but is not
limited to, desktop and laptop computers, servers, printers, telecopier machines
and telephones. We, as part of our routine modernization efforts, have completed
necessary upgrades to identified secondary software systems, such as word
processing, spreadsheet applications, telephone voicemail systems and computer
calendar programs. The software supplier of our accounting system completed its
Year 2000 upgrade and supplied us with Year 2000 compliant software at no cost
to us. We have substantially completed our internal testing of such software
with satisfactory results.

Tenant Compliance

We believe that the completion of the Project as scheduled will minimize Year
2000 related issues in our internal operations. However, we may still be
adversely impacted by Year 2000 related issues as a result of problems outside
our control, such as the inability of tenants to pay rent when due. In order to
gauge such risk, we sent questionnaires to each of our then existing tenants in
August 1998 to assess their Year 2000 compliance status. The responses to these
questionnaires continue to be received, reviewed and evaluated. Based on the
responses received, we do not anticipate any material adverse impact on the
orderly payment of monthly rent. Therefore, while there can be no assurance that
Year 2000 problems of tenants


                                       43


will not have a material adverse effect on our operating results or financial
condition, the information available to us indicates such an occurrence is not
likely.

Property Compliance

Our property managers have completed Phase I of the Project, a building by
building survey of all of our properties to determine whether building support
systems such as heat, power, light, security, garages and elevators will be
affected by the advent of the Year 2000. Most of such systems either are already
Year 2000 compliant or contain no computerized parts. Our property managers have
completed Phase II of the Project, the development and implementation of action
plans to modify, upgrade or replace non-compliant building systems. The
compliance testing of these installed building systems is in progress pursuant
to Phase III of the Project.

We have communicated with vendors of building systems or other services to our
buildings regarding their Year 2000 compliance. In many instances, we will rely
on the written representations from these vendors regarding the Year 2000
compliance of their product or service. We are also relying on assurances
requested from utility providers of their Year 2000 compliance and their
continued ability to provide uninterrupted service to our buildings. We
anticipate incurring a total cost of approximately $1.0 million in costs to
modify, upgrade and/or replace identified building support systems for Year 2000
compliance.

Worst Case Exposure

We are aware that it is generally believed that the Year 2000 problem, if
uncorrected, may result in a worldwide economic crisis. We are unable to
determine whether such predictions are true or false. However, if such
predictions prove true, we assume that all companies (including ours) will
experience the effects in one way or another. The most reasonably likely worst
case scenario we anticipate in connection with the Year 2000 issue relates to
the failure of the upgrade to our accounting system to effectively become Year
2000 compliant. We believe that such an event is most unlikely, but an
occurrence of the foregoing might have a material adverse impact on our
operations. We cannot currently assess the financial impact of such a worst case
scenario.

Contingency Plans

We are developing contingency plans to address the Year 2000 non-compliance of
(i) critical building support systems and (ii) our accounting system.

      Critical Building Systems. We believe that the failure of any of the
following critical building support systems due to Year 2000 issues could have a
material adverse impact on the performance of an individual building: security
systems, elevator systems or fire/life safety systems. We believe that in the
event of a Year 2000 related failure in a building security system, we would be
able to maintain adequate security at the building through the use of security
guards. We believe that in the event of a Year 2000 related failure in a
building elevator system, adequate access would exist at most of our buildings
through existing stairways. We believe that in the event of a Year 2000 related
failure in a building fire/life safety system, our property management staff
would be able to manually operate such system.

      Accounting Software. We believe that failure of the Year 2000 compliance
upgrade to our accounting software might have a material adverse impact on our
operations. However, we believe that financial data within any given fiscal year
will remain intact and retrievable. We believe that alternative accounting
software and/or manual bookkeeping would minimize the impact of a Year 2000
related failure of our current accounting software.

Risks

The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. Such failures could materially and adversely affect our results of
operations, liquidity and financial condition. Due to the general uncertainty
inherent in the Year 2000 problem, resulting in part from the uncertainty of the
Year 2000 readiness of third-party vendors and tenants, we are unable to
determine at this time whether the consequences of Year 2000 failures will have
a material impact on our results of operations, liquidity or financial
condition. The Project is expected to significantly reduce our level of
uncertainty about the Year 2000 problem. We believe that, with the
implementation and completion of the Project as scheduled, the possibility of
significant interruptions of normal operations should be reduced.
