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.

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
                  6, 1999 (59,109,277 shares), distributions payable to minority
                  interest common unitholders (8,299,690 common units) on that
                  same date and preferred distributions to preferred unitholders
                  (229,304 preferred units) for the second quarter 1999. The
                  second quarter 1999 dividends and common unit distributions of
                  $0.55 per share and per common unit (pro-rated for units
                  issued during the quarter), as well as the second quarter
                  preferred unit distribution of $16.875 per preferred unit,
                  were approved by the Board of Directors on June 10, 1999 and
                  paid on July 23,1999.

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

--------------------------------------------------------------------------------
   7.00% Senior Unsecured Notes, due March 15, 2004          $299,624     7.27%
   7.25% Senior Unsecured Notes, due March 15, 2009          $297,720     7.49%
--------------------------------------------------------------------------------

   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.

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.

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.

(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.

10. MINORITY INTEREST

Minority interest in the accompanying consolidated financial statements relates to common units in the Operating Partnership, in addition to preferred units
("Preferred Units") and warrants to purchase common units ("Unit Warrants")
issued in connection with the Company's December 1997 acquisition of 54 office properties ("Mack Properties") from the Mack Company and Patriot American Office Group ("Mack Transaction"), held by parties other than the Company.

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.

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.

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.

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 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.

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.

COMMON STOCK

On February 25, 1998, the Company completed an underwritten public offer and sale of 2,500,000 shares of its common stock and used the net proceeds, which totaled approximately $92,194 (after offering costs) to pay down a portion of its outstanding borrowings under the Company's credit facilities and fund the acquisition of 10 Mountainview Road (see Note 3).

On March 18, 1998, in connection with the acquisition of Prudential Business Campus, the Company completed an offer and sale of 2,705,628 shares of its common stock using the net proceeds of approximately $99,899 (after offering costs) in the funding of such acquisition (see Note 3).

Purchases 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 of approximately $25,058. Concurrent with these purchases, the Company sold to the Operating Partnership 854,700 common units for approximately $25,058.

For the six months ended June 30, 1999, the Company purchased, for constructive retirement, 26,000 shares of its outstanding common stock for an aggregate cost of approximately $713.

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.

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.

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.

Base rents for the Same-Store Properties increased $7.5 million, or 3.8 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 $3.8 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.

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.

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 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.

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.

Section 21E of The Securities Exchange Act of 1934. 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.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Approximately $1.3 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 the market interest rates. The following table presents principal cash flows (in thousands) based upon maturity dates of the debt obligations and the related weighted-average interest rates by expected maturity dates for the fixed rate debt. The interest rate on the variable rate debt as of June 30, 1999 ranged from LIBOR plus 0.65 percent to LIBOR plus 0.90 percent.

Section 2.2 Limitation on Aggregate Principal Amount.

The aggregate principal amount of the Notes shall be limited to $185,283,478, and, except as provided in this Section and in Section 306 of the Original Indenture, the Issuer shall not execute and the Trustee shall not authenticate or deliver Notes in excess of such aggregate principal amount.

Nothing contained in this Section 2.2 or elsewhere in this Supplemental Indenture, or in the Notes, is intended to or shall limit execution by the Issuer or authentication or delivery by the Trustee of Notes under the circumstances contemplated by Sections 303, 304, 305, 306, 906, 1107 and 1305 of the Original Indenture.

Section 2.3 Interest and Interest Rates; Maturity Date of Notes.

The Notes will bear interest at a rate of 7.18% per annum from August __, 1999 or from the immediately preceding Interest Payment Date to which interest has been paid or duly provided for, payable monthly in arrears on the first Business Day of each month, commencing on September 1, 1999 (each, an "Interest Payment Date"), to the Person in whose name such Note is registered at the close of business on the last Business Day of the month preceding the relevant Interest Payment Date (each, a "Regular Record Date"). Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest so payable on any Note which is not punctually paid or duly provided for on any Interest Payment Date shall forthwith cease to be payable to the Person in whose name such Note is registered on the relevant Regular Record Date, and such defaulted interest shall instead be payable to the Person in whose name such Note is registered on the Special Record Date or other specified date determined in accordance with the Original Indenture.

If any Interest Payment Date or Maturity falls on a day that is not a Business Day, the required payment shall be made on the next Business Day as if it were made on the date such payment was due and no interest shall accrue on the amount so payable for the period from and after such Interest Payment Date or Maturity, as the case may be.

The Notes will mature on December 31, 2003.

Section 2.4 Limitations on Incurrence of Indebtedness.

(a) The Issuer will not, and will not permit any Subsidiary to,

7

incur any Indebtedness, other than Intercompany Indebtedness, if, immediately after giving effect to the incurrence of such additional Indebtedness and the application of the proceeds thereof, the aggregate principal amount of all outstanding Indebtedness of the Issuer and its Subsidiaries on a consolidated basis determined in accordance with GAAP is greater than 60% of the sum of (without duplication) (i) the Total Assets of the Issuer and its Subsidiaries as of the end of the calendar quarter covered in the Issuer's Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Indebtedness and
(ii) the purchase price of any assets included in the definition of Total Assets acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire items included in the definition of Total Assets or used to reduce indebtedness), by the Issuer or any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Indebtedness.

(b) In addition to the limitation set forth in subsection (a) of this Section 2.4, the Issuer will not, and will not permit any Subsidiary to, incur any Indebtedness if the ratio of Consolidated Income Available for Debt Service to the Annual Service Charge for the four consecutive fiscal quarters most recently ended prior to the date on which such additional Indebtedness is to be incurred shall have been less than 1.5:1, on a pro forma basis after giving effect thereto and to the application of the proceeds therefrom, and calculated on the assumption that (i) such Indebtedness and any other Indebtedness incurred by the Issuer and its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Indebtedness, had occurred at the beginning of such period; (ii) the repayment or retirement of any other Indebtedness by the Issuer and its Subsidiaries since the first day of such four-quarter period had been repaid or retired at the beginning of such period (except that, in making such computation, the amount of Indebtedness under any revolving credit facility shall be computed based upon the average daily balance of such Indebtedness during such period); (iii) in the case of Acquired Indebtedness or Indebtedness incurred in connection with any acquisition since the first day of such four-quarter period, the related acquisition had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition being included in such pro forma calculation; and (iv) in the case of any acquisition or disposition by the Issuer or its Subsidiaries of any asset or group of assets since the first day of such four-quarter period, whether by merger, stock purchase or sale, or asset purchase or sale, such acquisition or disposition or any related repayment of Indebtedness had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation.

(c) In addition to the limitations set forth in subsections (a) and
(b) of this Section 2.4, the Issuer will not, and will not permit any Subsidiary to, incur any Indebtedness secured by any Encumbrance upon any of the property of the

8

Issuer or any Subsidiary, whether owned at the date of the Indenture or thereafter acquired, if, immediately after giving effect to the incurrence of such additional Indebtedness secured by an Encumbrance and the application of the proceeds thereof, the aggregate principal amount of all outstanding Indebtedness of the Issuer and its Subsidiaries on a consolidated basis which is secured by any Encumbrance on property of the Issuer or any Subsidiary is greater than 40% of the sum of (without duplication) (i) the Total Assets of the Issuer and its Subsidiaries as of the end of the calendar quarter covered in the Issuer's Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, most recently filed with the Commission (or, if such filing is not permitted under the Exchange Act, with the Trustee) prior to the incurrence of such additional Indebtedness and (ii) the purchase price of any assets included in the definition of Total Assets acquired, and the amount of any securities offering proceeds received (to the extent such proceeds were not used to acquire items included in the definition of Total Assets or used to reduce Indebtedness), by the Issuer or any Subsidiary since the end of such calendar quarter, including those proceeds obtained in connection with the incurrence of such additional Indebtedness.

(d) The Issuer and its Subsidiaries may not at any time own Total Unencumbered Assets equal to less than 150% of the aggregate outstanding principal amount of the Unsecured Indebtedness of the Issuer and its Subsidiaries on a consolidated basis.

(e) For purposes of this Section 2.4, Indebtedness shall be deemed to be "incurred" by the Issuer or a Subsidiary whenever the Issuer or such Subsidiary shall create, assume, guarantee or otherwise become liable in respect thereof.

Section 2.5 Redemption.

The Notes may be redeemed at any time at the option of the Issuer, in whole or in part, at a redemption price equal to the sum of (i) the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon up to but not including the Redemption Date and (ii) the Make-Whole Premium, if any, with respect to such Notes (the "Redemption Price").

Section 2.6 Places of Payment.

The Places of Payment where the Notes may be presented or surrendered for payment, where the Notes may be surrendered for registration of transfer or exchange and where notices and demands to and upon the Issuer in respect of the Notes and the Original Indenture may be served shall be in Wilmington, Delaware, and the office or agency for such purpose shall initially be located at the Corporate Trust Office.

Section 2.7 Method of Payment.

9

Payment of the principal of and interest on the Notes will be made at the office or agency of the Issuer maintained for that purpose in Wilmington, Delaware (which shall initially be an office or agency of the Trustee), in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Issuer, payments of principal and interest on the Notes (other than payments of principal and interest due at Maturity) may be made (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) by wire transfer to an account maintained by the Person entitled thereto located within the United States.

7.18% NOTE DUE 2003

MACK-CALI REALTY, L.P., a limited partnership duly organized and existing under the laws of the State of Delaware (herein referred to as the "Issuer" which term shall include any Successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, upon presentation, the principal sum of ONE HUNDRED EIGHTY-FIVE MILLION TWO HUNDRED EIGHTY-THREE THOUSAND FOUR HUNDRED SEVENTY-EIGHT AND 00/100 DOLLARS on December 31, 2003, and to pay interest on the outstanding principal amount thereon from August 2, 1999, or from the immediately preceding Interest Payment Date to which interest has been paid or duly provided for, monthly in arrears on the first Business Day of each month in each year, commencing September 1, 1999, at the rate of 7.18% per annum, until the entire principal hereof is paid or made available for payment. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in the Indenture, be paid to the Person in whose name this Security is registered at the close of business on the Regular Record Date for such interest which shall be the last Business Day of the month preceding the relevant Interest Payment Date. Any such interest not so punctually paid or duly

15

provided for shall forthwith cease to be payable to the Holder on such Regular Record Date, and may either be paid to the Person in whose name this Security is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of the Securities not more than 15 days and not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. Payment of the principal of and interest on this Security will be made at the office or agency maintained for that purpose in the City of Wilmington, Delaware or elsewhere as provided in the Indenture, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Issuer payments of principal and interest on the Notes (other than payments of principal and interest due at Maturity) may be made (i) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or
(ii) by wire transfer to an account of the Person entitled thereto located within the United States.

Securities of this series are one of a duly authorized issue of securities of the Issuer (herein called the "Securities"), issued and to be issued in one or more series under an Indenture, dated as of March 16, 1999, among the Issuer, Mack-Cali Realty Corporation and Wilmington Trust Company, (herein called the "Trustee," which term includes any successor trustee under the Indenture), as supplemented by Supplemental Indenture No. 1, dated as of March 16, 1999, as further supplemented by Supplemental Indenture No. 2, dated as of August 2, 1999 (as so supplemented, herein called the "Indenture"), between the Issuer and the Trustee to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Trustee and the Holders of the Securities and of the terms upon which the Securities are authenticated and delivered. This Security is one of the series designated in the first page thereof, limited in aggregate principal amount to $185,283,478.

Securities of this series may be redeemed at any time at the option of the Issuer, in whole or in part, upon notice of not more than 60 nor less than 30 days prior to the Redemption Date, at a redemption price equal to the sum of (i) the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon up to but not including the Redemption Date and (ii) the Make-Whole Premium, if any.

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the Issuer on this Security and (b) certain restrictive covenants and the related defaults and Events of Default applicable to the Issuer, in each case, upon compliance by the Issuer with certain conditions set forth in the Indenture,

16

which provisions apply to this Security.

If an Event of Default with respect to the Securities shall occur and be continuing, the principal of the Securities may be declared due and payable in the manner and with the effect provided in the Indenture.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities, the Holders of not less than a majority in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any interest on or after the respective due dates expressed herein.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Issuer and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of each series of Securities then Outstanding affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of (and Make-Whole Premium, if any) and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

Except as set forth in Section 302 of the Indenture, the Securities of this series are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Issuer may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Security for registration of transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Issuer, the Trustee nor any such agent shall be affected by notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in this Security, or because of any indebtedness evidenced hereby or thereby, shall be had against any promoter, as such, or against any past, present or future shareholder, officer or director, as such, of the Issuer or of any successor, either directly or through the Issuer or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance of this Security by the Holder thereof and as part of the consideration for the issue of the Securities of this series.

The Operating Partnership is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and has all requisite power and authority to own its properties and to carry on its business as now conducted and as proposed to be conducted. The Operating Partnership is duly qualified as a foreign limited partnership to do business in and is in good standing in each jurisdiction in which the character of the properties owned or held under lease by it or the nature of the business now conducted by it and proposed to be conducted by it requires such qualification, except where the failure to be so qualified or to be in good standing would not have a Material Adverse Effect. As used in this Agreement, "Material Adverse Effect" means a material adverse effect on (a) the business, operations, affairs, financial condition, assets or properties of the Operating Partnership and its subsidiaries taken as a whole, or (b) the ability of the Operating Partnership to perform its obligations under this Agreement and the Notes, or (c) the validity or enforceability of this Agreement or the Notes.

(2) Authorization. The Operating Partnership has all requisite power and authority to enter into this Agreement, the Original Indenture and the Supplemental Indenture (all of the foregoing Agreements being referred to herein collectively as the


"Transaction Documents"), to issue the Notes and to perform its obligations pursuant to the provisions hereof and thereof. The execution and delivery of the Transaction Documents and the Notes have been duly authorized by all requisite action on the part of the Operating Partnership. This Agreement constitutes, and each of the other Transaction Documents and the Notes will constitute the legal, valid and binding obligations of the Operating Partnership, enforceable against the Operating Partnership in accordance with their respective terms, except as limited by general equitable principles and by applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting the rights of creditors generally.

(3) Compliance with Securities Laws; Disclosure. The Registration Statement and the Prospectus (i) comply in all material respects with the Securities Act of 1933, as amended (the "Securities Act") and the applicable rules and regulations thereunder, (ii) correctly describe in all material respects the business of the Operating Partnership and (iii) do not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(4) Priority. The Notes will constitute senior unsecured obligations of the Operating Partnership, ranking equally with such of the Operating Partnership's existing and future senior unsecured and unsubordinated indebtedness.

(5) Compliance with Other Instruments. The consummation of the transactions contemplated by this Agreement and the performance of the terms and provisions of the Transaction Documents and the Notes will not result in any breach of, or constitute a default under, or result in the creation of any lien in respect of any property of the Operating Partnership under, any indenture, mortgage, deed of trust, bank loan or credit agreement, organizational instrument, or other agreement or instrument to which the Operating Partnership is a party or by which the Operating Partnership or any of its properties is bound except where such breach, default or creation could not reasonably be expected to result in a Material Adverse Effect. The Operating Partnership is not in violation of, in default under or in breach of any agreement or instrument to which the Operating Partnership or any of its properties is bound, except where such violation, default or breach would not have a Material Adverse Effect.

(6) Governmental Consents. Except for the filing of the Registration Statement and the Prospectus, no consent, approval or authorization of, or registration, filing or declaration with, any Governmental Body is required for the execution, delivery or performance by the Operating Partnership of the Transaction Documents and the Notes.


(7) Litigation; Governmental Orders. There are no actions, suits or proceedings pending or, to the knowledge of the Operating Partnership, threatened against the Operating Partnership or any of its properties in any court or before any arbitrator or Governmental Body, except for those actions, suits or proceedings an adverse decision with respect to which would not have a Material Adverse Effect. The Operating Partnership is not, and the consummation of the transactions contemplated by this Agreement and the performance of the terms and provisions of the Transaction Documents and the Notes will not cause the Operating Partnership to be, (i) in default under any Order of any court, arbitrator or Governmental Body, (ii) subject to any Order of any court or Governmental Body or (iii) in violation of any statute or other rule or regulation of any Governmental Body, the violation of which would have a Material Adverse Effect.

As used in this Agreement, the term "Governmental Body" includes any applicable federal, state, county, city, municipal or other governmental department, commission, board, bureau, agency, authority or instrumentality, whether domestic or foreign; and the term "Order" includes any order, writ, injunction, decree, judgment, award, determination or written direction or demand.

(8) Taxes. The Operating Partnership has filed all tax returns that are required to have been filed by it in any jurisdiction. All taxes shown to be due and payable on such returns and all other taxes and assessments payable by the Operating Partnership, to the extent the same have become due and payable, have been paid. The Operating Partnership does not know of any proposed material tax assessment against the Operating Partnership and, in the opinion of the Operating Partnership, all of its tax liabilities are adequately provided for on the books of the Operating Partnership.

(9) Compliance with ERISA. (i) The Operating Partnership and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of non-compliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Operating Partnership nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA) and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Operating Partnership or any ERISA Affiliate, or in the imposition of any lien on any of the rights, properties or assets of the Operating Partnership or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such


liabilities or liens as would not be individually or in the aggregate Material.

(ii) The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan's most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan's most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term "benefit liabilities" has the meaning specified in Section 4001 of ERISA and the terms "current value" and "present value" have the meaning specified in Section 3 of ERISA.

(iii) The Operating Partnership and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to contingent withdrawal liabilities) under Section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material.

(iv) The expected postretirement benefit obligation (determined as of the last day of the Operating Partnership's most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by Section 4980B of the Code) of the Operating Partnership and its subsidiaries is not Material.

Exhibit A

August 2, 1999

Teachers Insurance and Annuity Association of America 730 Third Avenue
New York, New York 10017

Re: Purchase of Unsecured Notes by Teachers Insurance and Annuity Association of America

Dear Sirs:

We have acted as counsel to Mack-Cali Realty, L.P., a Delaware limited partnership (the "Operating Partnership"), and the Operating Partnership's general partner, Mack-Cali Realty Corporation, a Maryland corporation (the "Company"), in connection with the issuance and sale by the Operating Partnership of $185,283,478 of 7.18% notes due 2003 (the "Securities"). The Securities are being sold by the Operating Partnership pursuant to the Note Purchase Agreement, dated as of August 2, 1999 (the "Note Purchase Agreement"), between the Operating Partnership and Teachers Insurance and Annuity Association of America, a New York corporation ("TIAA"). Terms not defined herein have the meanings ascribed to them in the Note Purchase Agreement.

In so acting, we have participated in the preparation of the Base Indenture, Supplemental Indenture No. 2, the Base Prospectus and the Prospectus Supplement. We have examined originals or copies certified or otherwise identified to our satisfaction, of such documents, necessary or appropriate for purposes of rendering this opinion, including (a) the Certificate of Limited Partnership of the Operating Partnership, (b) the Second Amended and Restated Agreement of Limited Partnership, as amended, of the Operating Partnership, (c) the Note Purchase Agreement, (d) a proof of a specimen note, (e) the Prospectus Supplement, (f) the Shelf Registration Statement, (g) certificates prepared for purposes of this opinion and (h) such other documents, records and other instruments and matters of law as we have deemed necessary or appropriate for purposes of this opinion. In all such examinations, we have assumed the genuineness of all signatures on original and certified documents, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to executed documents of all unexecuted copies submitted to us, and the conformity to the originals of photostatic copies.

As to the various questions of fact material to our opinion stated to be "to the best of our


Teachers Insurance and Annuity Association of America August 2, 1999

Page 2

knowledge", and as otherwise specifically stated in our opinion, we have made inquiries of and relied upon oral statements, written information and certificates of officials and representatives of the Operating Partnership and the Company.

We are admitted to the Bar in the States of New York and New Jersey and we express no opinion as to the laws of any other jurisdiction, except the laws of the United States of America and the limited partnership laws of the State of Delaware.

Upon the basis of the foregoing and in reliance upon the representations made to us, we are of the opinion that:

1 The Operating Partnership has been duly organized and is validly existing as a limited partnership in good standing under the laws of the State of Delaware and is duly qualified to transact business and is in good standing under the laws of all other jurisdictions where the ownership or leasing of its properties or the conduct of its business requires such qualification, except where the failure to be so qualified does not amount to a material liability or disability to the Operating Partnership and its subsidiaries, taken as a whole.

2. The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Maryland and is duly qualified to transact business and is in good standing under the laws of all other jurisdictions where the ownership or leasing of its properties or the conduct of its business requires such qualification, except where the failure to be so qualified does not amount to a material liability or disability to the Company and its subsidiaries, taken as a whole.

3. The Operating Partnership, the Company and each of their subsidiaries have full power, corporate or other, to own or lease their respective properties and conduct their respective businesses as described in the Base Prospectus and the Prospectus Supplement, and the Operating Partnership has full power, partnership or other, to enter into the Note Purchase Agreement, the Base Indenture and the Supplemental Indenture and to carry out all the terms and provisions thereof to be carried out by it.

4. The Securities have been duly authorized by all necessary partnership action, and when executed and delivered against payment therefor in the manner provided in the Note Purchase Agreement, the Securities will be the legal, valid, binding and enforceable obligation of the Operating Partnership entitled to the benefits provided by the Base Indenture and the Supplemental Indenture, subject to the effect of bankruptcy, insolvency, moratorium, fraudulent conveyance, reorganization and similar laws relating to creditors' rights generally and the application of equitable principles in any proceeding, whether at law or in equity. The Operating Partnership has complied with all conditions precedent or covenants with respect to the


Teachers Insurance and Annuity Association of America August 2, 1999

Page 3

authentication and delivery of the Securities under the Base Indenture and the Supplemental Indenture.

5. No partner of the Operating Partnership is entitled as such to any preemptive or other rights to subscribe for any of the Securities and no holder of securities of the Operating Partnership or any subsidiary has any right which has not been waived to require the Operating Partnership to register the offer or sale of any securities owned by such holder under the Act in the public offering contemplated by the Note Purchase Agreement.

6. The form and terms of the Securities have been established in conformity with the provisions of the Base Indenture and the Supplemental Indenture.

7. The execution and delivery of the Note Purchase Agreement, the Base Indenture and the Supplemental Indenture have been duly authorized by all necessary action of the Operating Partnership, and the Note Purchase Agreement, the Base Indenture and the Supplemental Indenture have been duly executed and delivered by the Operating Partnership, and are valid and binding agreements of the Operating Partnership, enforceable against the Operating Partnership in accordance with their terms, subject to the effect of bankruptcy, insolvency, moratorium, fraudulent conveyance, reorganization and similar laws relating to creditors' rights generally and to the application of equitable principles in any proceeding, whether at law or in equity, and except as rights to indemnity and contribution may be limited by federal or state securities laws or principles of public policy.

8. (A) No legal or governmental proceedings are pending to which the Operating Partnership, any of its subsidiaries, or any of their senior management in their capacity as such, is a party or to which the Properties or any other property of the Operating Partnership or any of its subsidiaries is subject that are required to be described in the Prospectus Supplement or the Shelf Registration Statement and are not described therein, and, to the best of our knowledge, no such proceedings have been threatened against the Operating Partnership or any of its subsidiaries or with respect to the Properties or any of their respective other properties and (B) no contract or other document is required to be described in the Prospectus Supplement that is not described therein.

9. The issuance, offering and sale of the Securities to TIAA by the Operating Partnership pursuant to the Note Purchase Agreement, the compliance by the Operating Partnership with the other provisions of the Note Purchase Agreement, and the consummation of the other transactions contemplated by the Note Purchase Agreement do not (A) require the consent, approval, authorization, registration or qualification of or with any governmental authority, except such as have been obtained and such as may be required under state securities


Teachers Insurance and Annuity Association of America August 2, 1999

Page 4

or blue sky laws (as to which we do not opine) or (B) conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the Properties or any other properties or assets of the Operating Partnership or any of its subsidiaries pursuant to any indenture, mortgage, deed of trust, lease or other agreement or instrument known to us after due inquiry to which the Operating Partnership or any of its subsidiaries is a party or by which the Operating Partnership or any of its subsidiaries or the Properties or any other of their respective properties are bound, the Second Amended and Restated Agreement of Limited Partnership or other organizational documents, as the case may be, of the Operating Partnership or any of its subsidiaries, or any statute, or (to the best of our knowledge after due inquiry) any judgment, decree, order, rule or regulation of any court or other governmental authority or any arbitrator applicable to the Operating Partnership or any of its subsidiaries or any of the Properties.

10. The Operating Partnership is not subject to registration as an Investment Company under the Investment Company Act of 1940, as amended, and the transactions contemplated by the Note Purchase Agreement will not cause the Operating Partnership to become an investment company subject to registration under such Act.

11. The Prospectus Supplement will be filed with the Securities and Exchange Commission in the manner and within the time period required by Rule
424(b); and the Shelf Registration Statement has been declared effective under the Securities Act and no stop order suspending the effectiveness of the Shelf Registration Statement and no order directed at any document incorporated by reference in the Prospectus Supplement or any amendment or supplement thereto has been issued, and no proceedings for that purpose have been instituted or, to the best of our knowledge, threatened by the Securities and Exchange Commission.

12. The Registration Statement and each amendment thereto, and the Prospectus Supplement (in each case, including the documents incorporated by reference therein but not including the financial statements and other financial or statistical data included therein or omitted therefrom, as to which we express no opinion) comply as to form in all material respects with the applicable requirements of the Securities Act, the Exchange Act and the rules and regulations of the Securities and Exchange Commission thereunder.

13. The statements in the Base Prospectus under the caption entitled "Description of Debt Securities," insofar as they purport to summarize certain provisions of the Base Indenture, are accurate summaries of such provisions. The statements in the Prospectus Supplement under the caption entitled "Description of the Notes," insofar as they purport to summarize certain provisions of the Supplemental Indenture and the Notes, are accurate summaries of such provisions.

THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of July 1, 1999, by and between Mitchell E. Hersh, an individual residing at 15 Parkwood Drive, Wayne, New Jersey 07470 ("Executive"), and Mack-Cali Realty Corporation, a Maryland corporation with offices at 11 Commerce Drive, Cranford, New Jersey 07016 (the "Company").

RECITALS

WHEREAS, Executive has served as President and Chief Operating Officer and as a member of the Board of Directors of the Company (the "Board") pursuant to his prior employment agreement dated as of December 1997 (the "Prior Agreement") entered into as of the closing of the combination of Cali Realty Corporation with the Mack Companies (the "Mack Combination");

WHEREAS, Executive was appointed Chief Executive Officer of the Company on April 18, 1999;

WHEREAS, the Company and the Executive wish to amend and restate the Prior Agreement in its entirety among other things to acknowledge Executive's appointment as Chief Executive Officer, to provide for an award of Restricted Shares and a Tax Gross-Up Payment (as defined in sub-paragraph 4(c) below), to change the Employment Period (as defined in sub-paragraph 2(a) below) to (4) years and to amend the amount of the severance payment Executive may be eligible to receive upon termination of employment with the Company; and

WHEREAS, the Company desires to continue to employ Executive as Chief Executive Officer and to continue to have Executive serve as a member of the Board


and Executive desires to continue to be employed by the Company as Chief Executive Officer and to continue to serve as member of the Board, pursuant to the amended and restated terms set forth herein and to restate the Prior Agreement in its entirety

NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:

1. Employment.

The Company hereby agrees to employ Executive, and Executive hereby agrees to accept such employment during the period and upon the terms and conditions set forth in this Agreement.

2. Employment Period.

(a) Except as otherwise provided in this Agreement to the contrary, the terms and conditions of this Agreement shall be and remain in effect during the period of employment (the "Employment Period") established under this Paragraph 2. The initial Employment Period shall be for a term commencing on the date of this Agreement and ending on the fourth anniversary of the date of this Agreement provided, however, that commencing on the day after the date of this Agreement and on each day thereafter, the Employment Period shall be extended for one additional day so that a constant four (4) year Employment Period shall be in effect, unless (i) the Company or Executive elects not to extend the term of this Agreement by giving written notice to the other party in accordance with Paragraph 19, in which case, subject to the provisions of sub-paragraph 5(a)(iv) below, the term of this Agreement shall become

2

fixed and shall end on the fourth anniversary of the date of such written notice ("Notice of Non-Renewal"), or (ii) Executive's employment terminates hereunder.

(b) Notwithstanding anything contained herein to the contrary: (i) Executive's employment with the Company may be terminated by the Company or Executive during the Employment Period, subject to the terms and conditions of this Agreement; and (ii) nothing in this Agreement shall mandate or prohibit a continuation of Executive's employment following the expiration of the Employment Period upon such terms and conditions as the Board and Executive may mutually agree.

(c) If Executive's employment with the Company is terminated, for purposes of this Agreement the term "Unexpired Employment Period" shall mean the period commencing on the date of such termination and ending on the last day of the Employment Period.

3. Services / Place of Employment.

(a) Services. During the Employment Period, Executive shall hold the position of Chief Executive Officer and shall serve as a member of the Board. Executive shall devote his best efforts and substantially all of his business time, skill and attention to the business of the Company (other than absences due to vacation, illness, disability or approved leave of absence), and shall perform such duties as are customarily performed by similar executive officers and as may be more specifically enumerated from time to time by the Board or Executive Committee of the Board; provided, however, that the foregoing is not intended to (a) preclude Executive from (i) owning and managing personal investments, including real estate investments, subject

3

to the restrictions set forth in Paragraph 13 hereof or (ii) engaging in charitable activities and community affairs, or (b) restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to those properties described in Schedule A, attached hereto, (the "Excluded Properties"), provided that the performance of the activities referred to in clauses (a) and (b) does not prevent Executive from devoting substantially all of his business time to the Company.

4. Compensation and Benefits.

(a) Salary. During the Employment Period, the Company shall pay Executive a minimum annual base salary in the amount of $1,050,000 (the "Annual Base Salary") payable in accordance with the Company's regular payroll practices. Executive's Annual Base Salary shall be reviewed annually in accordance with the policy of the Company from time to time and may be subject to upward adjustment based upon, among other things, Executive's performance, as determined in the sole discretion of the Option and Executive Compensation Committee of the Board (the "Compensation Committee"). In no event shall Executive's Annual Base Salary in effect at a particular time be reduced without his prior written consent.

(b) Incentive Compensation/Bonuses. In addition, Executive shall be eligible for incentive compensation payable each year in such amounts as may be

4

determined by the Compensation Committee. Executive shall be entitled to receive such bonuses, restricted share awards and options to purchase shares of common stock, par value $0.01 per share, of the Company (the "Common Stock") as the Board or the Compensation Committee as the case may be shall approve, in its sole discretion, including, without limitation, options, restricted share awards and bonuses contingent upon Executive's performance and the achievement of specified financial and operating objectives.

(c) Restricted Share Award/Tax Gross-Up Payment. Pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 1, 1998 (the "SOP"), Executive has been awarded a restricted share award of 62,500 shares of Common Stock ("Restricted Shares") as of July 1, 1999 (the "Restricted Share Award"). Executive shall be entitled to receive a tax gross-up payment (the "Tax Gross-Up Payment") from the Company with respect to each tax year in which Restricted Shares granted pursuant to the Restricted Share Award vest and are distributed to him. Each Tax Gross-Up Payment shall be a dollar amount equal to forty-three (43%) percent of the fair market value of the Restricted Shares at time of vesting, exclusive of dividends. In the event vesting occurs with respect to any Restricted Shares as a result of the achievement of the required performance goals, such payment shall be made as soon as practicable after a determination that the performance goals have been achieved but in no event later than the 90th day of the fiscal year of the Company immediately following the fiscal year as to which the performance goals were achieved. In the event vesting occurs for any other reason, including, without limitation, termination of

5

Executive's employment by the Company without Cause or by Executive for Good Reason (but excluding a termination by the Company for Cause or a voluntary quit without Good Reason by Executive), such payment shall be made as soon as practicable after the date of vesting but in no event later than the tenth
(10th) business day following such vesting.

(d) Taxes and Withholding. The Company shall have the right to deduct and withhold from all compensation all social security and other federal, state and local taxes and charges which currently are or which hereafter may be required by law to be so deducted and withheld.

(e) Additional Benefits. In addition to the compensation specified above and other benefits provided pursuant to this Paragraph 4, Executive shall be entitled to the following benefits:

(i) participation in the SOP, the Mack-Cali Realty Corporation
401(k) Savings and Retirement Plan (subject to statutory rules and maximum contributions and non-discrimination requirements applicable to 401(k) plans) and such other benefit plans and programs, including but not limited to restricted stock, phantom stock and/or unit awards, loan programs and any other incentive compensation plans or programs (whether or not employee benefit plans or programs), as maintained by the Company from time to time and made generally available to executives of the Company with such participation to be consistent with reasonable Company guidelines;

(ii) participation in any health insurance, disability insurance, paid vacation, group life insurance or other welfare benefit program made generally available to executives of the Company; and

(iii) participation in the security plan and reimbursement for reasonable business expenses incurred by Executive in furtherance of the interests of the Company.

6

As further consideration for Executive agreeing to serve as an officer and entering into the Prior Agreement upon the terms set forth therein, including, without limitation, the terms relating to non-competition set forth in Paragraph 13 of the Prior Agreement, the Company issued to Executive, warrants to purchase an aggregate of 339,976 shares of Common Stock at a purchase price equal to $38.75 per share ("Warrants"). Executive's Warrants are evidenced by the Warrant Agreement dated December 11, 1997 which includes, but is not limited to, the following provision: vesting over a five year period with one fifth (1/5) of the Warrants vesting on each of the first, second, third, fourth and fifth anniversaries of the date of the Warrant Agreement subject to acceleration in accordance with the terms of this Agreement.

(i) Cause. The Company shall have the right to terminate Executive's employment for Cause upon Executive's: (A) willful and continued failure to use best efforts to substantially perform his duties hereunder (other than any such failure resulting from Executive's incapacity due to physical or mental illness) for a period of thirty (30) days after written demand for substantial performance is delivered by the Company specifically identifying the manner in which the Company believes Executive has not substantially performed his duties; (B) willful misconduct and/or willful violation of Paragraph 11 hereof, which is materially economically injurious to the Company and the Partnership taken as a whole; (C) the willful violation of the provisions of Paragraph 13 hereof; or (D) conviction of, or plea of guilty to a felony.

(v) Without Cause. The Company shall have the right to terminate the Executive's employment hereunder without Cause subject to the terms and conditions of this Agreement.

Such termination shall be deemed a termination for Good Reason hereunder. For purposes of this Agreement "Change in Control" shall mean that any of the following events has occurred: (A) any "person" or "group" of persons, as such terms are used in Sections 13 and 14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than any employee benefit plan sponsored by the Company, becomes the "beneficial owner", as such term is used in Section 13 of the Exchange Act, (irrespective of any vesting or waiting periods) of (I) Common Stock or any class of stock convertible into Common Stock and/or (II) Common OP Units or preferred units or any other class of units convertible into Common OP Units, in an amount equal to twenty (20%) percent or more of the sum total of the Common Stock and the Common OP Units (treating all classes of outstanding stock, units or other securities convertible into stock units as if they were converted into Common Stock or Common OP Units as the case may be and then treating Common Stock and Common OP Units as if they were a single class) issued and outstanding immediately prior to such acquisition as if they were a single class and disregarding any equity raise in connection with the financing of such transaction; (B) any Common Stock is purchased pursuant to a tender or exchange offer other than an offer by the Company; (C) the dissolution or liquidation of the Company or the consummation of any merger or consolidation of the Company or any sale or other disposition of all or substantially all of its assets, if the shareholders of the Company and unitholders of the Partnership taken as a whole and considered as one class immediately before such transaction own, immediately after consummation of such transaction, equity securities and partnership units possessing less than fifty (50%) percent of the surviving or acquiring company and partnership taken as a whole; or (D) a turnover, during any two (2) year period, of the majority of the members of the Board, without the consent of the remaining members of the Board as to the appointment of the new Board members.

(b) Notice of Termination. Any termination of Executive's employment by the Company or any such termination by Executive (other than on account of death)

9

shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive's employment under the provision so indicated. In the event of the termination of Executive's employment on account of death, written Notice of Termination shall be deemed to have been provided on the date of death.

6. Compensation Upon Termination of Employment By the Company for Cause or By Executive without Good Reason.

In the event the Company terminates Executive's employment for Cause or Executive terminates his employment without Good Reason, the Company shall pay Executive any unpaid Annual Base Salary at the rate then in effect accrued through and including the date of termination. In addition, in such event, Executive shall be entitled (i) to receive any earned but unpaid incentive compensation or bonuses and (ii) to exercise any options which have vested and are exercisable in accordance with the terms of the applicable option grant agreement or plan, and (iii) to retain and/or receive any Restricted Shares which have vested as of the last day of the Company's fiscal year coincident or immediately preceding Executive's termination of employment and the corresponding Tax Gross-Up Payment (irrespective of whether the determination is made after Executive's termination of employment).

Except for any rights which Executive may have to unpaid salary amounts through and including the date of termination, earned but unpaid incentive compensation or bonuses, vested options, vested Restricted Shares and the

10

corresponding Tax Gross-Up Payment, the Company shall have no further obligations hereunder following such termination. The aforesaid amounts shall be payable in full immediately upon such termination.

7. Compensation Upon Termination of Employment Upon Death or Disability.

In the event of termination of Executive's employment as a result of either Executive's death or Disability, the Company shall pay to Executive, his estate or his personal representative the aggregate of (i) a cash payment of eight million dollars ($8,000,000) in full immediately upon such termination (the "Fixed Amount") and (ii) reimbursement of expenses incurred prior to date of termination ("Expense Reimbursement"). Executive (and Executive's dependents) shall also receive continuation of health coverage through the end of the Unexpired Employment Period on the same basis as health coverage is provided by the Company for active employees and as may be amended from time to time ("Medical Continuation").

In addition, all (A) incentive compensation payments or programs of any nature whether stock based or otherwise that are subject to a vesting schedule including, without limitation, the Warrants, the Restricted Share Award or any other restricted stock, phantom stock, units and any loan forgiveness arrangements granted to Executive ("Incentive Compensation") shall immediately vest as of the date of such termination ("Vested Incentive Compensation"), (B) options granted to Executive shall immediately vest as of the date of such termination (the "Vested Options") and Executive shall be entitled at the option of Executive, his estate or his personal representative, within one (1) year of the date of such termination, to exercise the

11

Vested Options and/or other options which have vested (including, without limitation, all other options which have previously vested in accordance with the Prior Agreement, any applicable option grant agreement or plan) (the "Total Vested Options") and are exercisable in accordance with the terms of the applicable option grant agreement or plan and/or any other methods or procedures for exercise applicable to optionees or to require the Company (upon written notice delivered within one hundred eighty (180) days following the date of Executive's termination) to repurchase all or any portion of Executive's vested options to purchase shares of Common Stock at a price equal to the difference between the Repurchase Fair Market Value (as hereinafter defined) of the shares of Common Stock for which the options to be repurchased are exercisable and the exercise price of such options as of the date of Executive's termination of employment (the "Vested Option Exercise Election"), and (C) the Tax Gross-Up Payment(s) applicable to the Restricted Share Award shall vest and be paid to Executive at such time as provided in sub-paragraph 4(c) above (the "Vested Tax Gross-Up Payments"). In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

Except for any rights which Executive or Executive's estate in the event of Executive's death may have to all of the above including the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation (which, in the event of Executive's death, shall be provided to Executive's

12

dependents), the Company shall have no further obligations hereunder following such termination.

For purposes of this Agreement, "Repurchase Fair Market Value" shall mean the average of the closing price on the New York Stock Exchange (or such other exchange on which the Common Stock is primarily traded) of the Common Stock on each of the trading days within the thirty (30) days immediately preceding the date of termination of Executive's employment.

8. Compensation Upon Termination of Employment By the Company Without Cause or By Executive for Good Reason.

In the event the Company terminates Executive's employment for any reason other than Cause or Executive terminates his employment for Good Reason, the Company shall pay to Executive and Executive shall be entitled to receive the aggregate of (i) the Fixed Amount and (ii) Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control. Executive understands that any options exercised more than ninety
(90) days following the date of his termination of employment which were granted as incentive stock options shall automatically be converted into non-qualified options.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical

13

Continuation, the Company shall have no further obligations hereunder following such termination. The parties both agree that the agreement to make these payments was consideration and an inducement to obtain Executive's consent to enter into this Agreement. The payments are not a penalty and neither party will claim them to be a penalty. Rather, the payments represent a fair approximation of reasonable amounts due to Executive for the Employment Period.

9. Change in Control.

(a) Options. Any Incentive Compensation and options granted to Executive that have not vested as of the date of a Change in Control shall immediately vest upon the date of the Change in Control. Neither the occurrence of a Change in Control, nor the vesting in any warrants or options as a result thereof shall require Executive to exercise any warrants or options. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

(b) Upon Termination. In the event Executive terminates his employment on or following a Change in Control as set forth in sub-paragraph
5(a)(vii), the Company shall pay to Executive and Executive shall be entitled to all the payments and rights Executive would have had if Executive had terminated his employment with Good Reason as set forth in Paragraph 8.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options (including, without limitation, by acceleration in accordance with sub-paragraph 9(a)) and the Vested Option Exercise

14

Election, the Vested Tax Gross-Up Payment, Expense Reimbursement, Medical Continuation and the Excise Tax Gross Up set forth in subparagraph 9(c), the Company shall have no further obligations hereunder following such termination.

(c) Excise Tax Gross Up. In addition, if it is determined by an independent accountant mutually acceptable to the Company and Executive that as a result of any payment in the nature of compensation made by the Company to (or for the benefit of) Executive pursuant to this Agreement or otherwise, an excise tax may be imposed on Executive pursuant to Section 4999 of the Code (or any successor provisions), the Company shall pay Executive in cash an amount equal to X determined under the following formula: (the "Excise Tax Gross Up"):

E x P

X = --------------------------------

            1-[(FI x (1-SLI)) + SLI + E + M]

where

E     =     the rate at which the excise tax is assessed under
            Section 4999 of the Code (or any successor provisions);

P     =     the amount with respect to which such excise tax is
            assessed, determined without regard to the Excise Tax
            Gross Up;

FI    =     the highest effective marginal rate of income tax
            applicable to Executive under the Code for the taxable
            year in question (taking into account any phase-out or
            loss of deductions, personal exemptions or other similar
            adjustments);

SLI   =     the sum of the highest effective marginal rates of
            income tax applicable to Executive under all applicable
            state and local laws for the taxable year in question
            (taking into account any phase-out or loss of
            deductions, personal exemptions and other similar
            adjustments); and

15

M     =     the highest marginal rate of Medicare tax applicable to
            Executive under the Code for the taxable year in
            question.

With respect to any payment in the nature of compensation that is made to (or for the benefit of) Executive under the terms of this Agreement or otherwise and on which an excise tax under Section 4999 of the Code (or any successor provisions) may be assessed, the payment determined under this sub-paragraph 9(c) shall be paid to Executive at the time of the Change in Control but prior to the consummation of the transaction with any successor. It is the intention of the parties that the Company provide Executive with a full tax gross-up under the provisions of this sub-paragraph, so that on a net after-tax basis, the result to Executive shall be the same as if the excise tax under Section 4999 of the Code (or any successor provisions) had not been imposed. The Excise Tax Gross Up may be adjusted if alternative minimum tax rules are applicable to Executive.

10. Mitigation / Effect on Employee Benefit Plans and Programs.

(a) Mitigation. Executive shall not be required to mitigate amounts payable under this Agreement by seeking other employment or otherwise, and there shall be no offset against amounts due Executive under this Agreement on account of subsequent employment. Amounts owed to Executive under this Agreement shall not be offset by any claims the Company may have against Executive and such payment shall not be affected by any other circumstances, including, without limitation, any counterclaim, recoupment, defense, or other right which the Company may have against Executive or others.

16

(b) Effect on Employee Benefit Programs. The termination of Executive's employment hereunder, whether by the Company or Executive, shall have no effect on the rights and obligations of the parties hereto under the Company's (i) welfare benefit plans including, without limitation, Medical Continuation as provided for herein and, health coverage thereafter but only to the extent required by law, and on the same basis applicable to other employees and (ii) 401(k) Plan but only to the extent required by law and pursuant to the terms of the 401(k) Plan.

11. Confidential Information.

(a) Executive understands and acknowledges that during his employment with the Company, he will be exposed to Confidential Information (as defined below), all of which is proprietary and which will rightfully belong to the Company. Executive shall hold in a fiduciary capacity for the benefit of the Company such Confidential Information obtained by Executive during his employment with the Company and shall not, directly or indirectly, at any time, either during or after his employment with the Company, without the Company's prior written consent, use any of such Confidential Information or disclose any of such Confidential Information to any individual or entity other than the Company or its employees, attorneys, accountants, financial advisors, consultants, or investment bankers except as required in the performance of his duties for the Company or as otherwise required by law. Executive shall take all reasonable steps to safeguard such Confidential Information and to protect such Confidential Information against disclosure, misuse, loss or theft.

17

(b) The term "Confidential Information" shall mean any information not generally known in the relevant trade or industry or otherwise not generally available to the public, which was obtained from the Company or its predecessors or which was learned, discovered, developed, conceived, originated or prepared during or as a result of the performance of any services by Executive on behalf of the Company or its predecessors. For purposes of this Paragraph 11, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

12. Return of Documents.

Except for such items which are of a personal nature to Executive (e.g., daily business planner), all writings, records, and other documents and things containing any Confidential Information shall be the exclusive property of the Company, shall not be copied, summarized, extracted from, or removed from the premises of the Company, except in pursuit of the business of the Company and at the direction of the Company, and shall be delivered to the Company, without retaining any copies, upon the termination of Executive's employment or at any time as requested by the Company.

13. Noncompete.

Executive agrees that:

(a) During the Employment Period and, in the event (i) the Company terminates Executive's employment for Cause, or (ii) Executive terminates his employment without Good Reason, for a one (1) year period thereafter, Executive shall

18

not, directly or indirectly, within the continental United States, engage in, or own, invest in, manage or control any venture or enterprise primarily engaged in any office-service, flex, or office property development, acquisition or management activities without regard to whether or not such activities compete with the Company. Nothing herein shall prohibit Executive from being a passive owner of not more than five percent (5%) of the outstanding stock of any class of securities of a corporation or other entity engaged in such business which is publicly traded, so long as he has no active participation in the business of such corporation or other entity. Moreover, the foregoing limitations shall not be deemed to restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to the Excluded Properties, if any, provided that during the Employment Period the performance of such activities does not prevent Executive from devoting substantially all of his business time to the Company.

(b) If, at the time of enforcement of this Paragraph 13, a court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable, the parties agree that reasonable maximum duration, scope, area or other restrictions may be substituted by such court for the stated duration, scope, area or other restrictions and upon substitution by such court, this Agreement shall be automatically modified without further action by the parties hereto.

(c) For purposes of this Paragraph 13, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

19

14. Remedies.

The parties hereto agree that the Company would suffer irreparable harm from a breach by Executive of any of the covenants or agreements contained in Paragraphs 11, 12 or 13 of this Agreement. Therefore, in the event of the actual or threatened breach by Executive of any of the provisions of Paragraphs 11, 12 or 13 of this Agreement, the Company may, in addition and supplementary to other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violation of the provisions thereof.

15. Indemnification/Legal Fees.

(a) Indemnification. In the event the Executive is made party or threatened to be made a party to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "Proceeding"), by reason of Executive's employment with or serving as an officer or director of the Company, whether or not the basis of such Proceeding is alleged action in an official capacity, the Company shall indemnify, hold harmless and defend Executive to the fullest extent authorized by Maryland law, as the same exists and may hereafter be amended, against any and all claims, demands, suits, judgments, assessments and settlements including all expenses incurred or suffered by Executive in connection therewith (including, without limitation, all legal fees incurred using counsel reasonably acceptable to Executive) and such indemnification shall continue as to Executive even after Executive is no longer employed by the Company and shall inure to the benefit of his heirs, executors, and

20

administrators. Expenses incurred by Executive in connection with any Proceeding shall be paid by the Company in advance upon request of Executive that the Company pay such expenses; but, only in the event that Executive shall have delivered in writing to the Company an undertaking to reimburse the Company for expenses with respect to which Executive is not entitled to indemnification. The provisions of this Paragraph shall remain in effect after this Agreement is terminated irrespective of the reasons for termination. The indemnification provisions of this Paragraph shall not supersede or reduce any indemnification provided to Executive under any separate agreement, or the by-laws of the Company since it is intended that this Agreement shall expand and extend the Executive's rights to receive indemnity.

(b) Legal Fees. If any contest or dispute shall arise between the Company and Executive regarding or as a result of any provision of this Agreement, the Company shall reimburse Executive for all legal fees and expenses reasonably incurred by Executive in connection with such contest or dispute, but only if Executive is successful in respect of substantially all of Executive's claims pursued or defended in connection with such contest or dispute. Such reimbursement shall be made as soon as practicable following the resolution of such contest or dispute (whether or not appealed).

16. Successors and Assigns.

(a) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance

21

satisfactory to Executive, to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such agreement prior to the effectiveness of an such succession shall be a breach of this Agreement and shall entitle Executive to compensation from the Company in the same amount and on the same terms as he would be entitled to hereunder if Executive terminated his employment hereunder within six (6) months of a Change in Control as set forth in Paragraph 9, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the date of termination. In the event of such a breach of this Agreement, the Notice of Termination shall specify such date as the date of termination. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to all or substantially all of its business and/or its assets as aforesaid which executes and delivers the agreement provided for in this Paragraph 16 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law. Any cash payments owed to Executive pursuant to this Paragraph 16 shall be paid to Executive in a single sum without discount for early payment immediately prior to the consummation of the transaction with such successor.

(b) This Agreement and all rights of Executive hereunder may be transferred only by will or the laws of descent and distribution. Upon Executive's death, this Agreement and all rights of Executive hereunder shall inure to the benefit of and be enforceable by Executive's beneficiary or beneficiaries, personal or legal representatives, or estate, to the extent any such person succeeds to Executive's

22

interests under this Agreement. Executive shall be entitled to select and change a beneficiary or beneficiaries to receive any benefit or compensation payable hereunder following Executive's death by giving Company written notice thereof. If Executive should die following the date of termination while any amounts would still be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons so appointed in writing by Executive, including, without limitation, under any applicable plan, or otherwise to his legal representatives or estate.

17. Timing of and No Duplication of Payments.

All payments payable to Executive pursuant to this Agreement shall be paid as soon as practicable after such amounts have become fully vested and determinable. In addition, Executive shall not be entitled to receive duplicate payments under any of the provisions of this Agreement.

18. Modification or Waiver.

No amendment, modification, waiver, termination or cancellation of this Agreement shall be binding or effective for any purpose unless it is made in a writing signed by the party against whom enforcement of such amendment, modification, waiver, termination or cancellation is sought. No course of dealing between or among the parties to this Agreement shall be deemed to affect or to modify, amend or discharge any provision or term of this Agreement. No delay on the part of the Company or Executive in the exercise of any of their respective rights or remedies shall operate as a waiver thereof, and no single or partial exercise by the Company or

23

Executive of any such right or remedy shall preclude other or further exercise thereof. A waiver of right or remedy on any one occasion shall not be construed as a bar to or waiver of any such right or remedy on any other occasion.

The respective rights and obligations of the parties hereunder shall survive the Executive's termination of employment and termination of this Agreement to the extent necessary for the intended preservation of such rights and obligations.

19. Notices.

All notices or other communications required or permitted hereunder shall be made in writing and shall be deemed to have been duly given if delivered by hand or delivered by a recognized delivery service or mailed, postage prepaid, by express, certified or registered mail, return receipt requested, and addressed to the President of the Company or Executive, as applicable, at the address set forth above (or to such other address as shall have been previously provided in accordance with this Paragraph 19).

20. Governing Law.

This agreement will be governed by and construed in accordance with the laws of the State of New Jersey except as to Paragraph 15(a), without regard to principles of conflicts of laws thereunder.

21. Severability.

Whenever possible, each provision and term of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any

24

provision or term of this Agreement shall be held to be prohibited by or invalid under such applicable law, then, subject to the provisions of sub-paragraph 13(b) above, such provision or term shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or affecting in any manner whatsoever the remainder of such provisions or term or the remaining provisions or terms of this Agreement.

22. Legal Representation.

Each of the Company and Executive have been represented by counsel with respect to this Agreement.

23. Counterparts.

This Agreement may be executed in separate counterparts, each of which is deemed to be an original and both of which taken together shall constitute one and the same agreement.

24. Headings.

The headings of the Paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute a part hereof and shall not affect the construction or interpretation of this Agreement.

25. Entire Agreement.

This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all other prior agreements and undertakings, both written and oral, among the parties with respect to the subject matter hereof. The parties recognize that the Prior Agreement has been amended and restated in its

25

entirety by this Agreement and the terms of the Prior Agreement are of no further force and effect.

26. Survival of Agreements.

The covenants made in Paragraphs 5 through 15 and 21 each shall survive the termination of this Agreement.

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the date first above written.

SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT

THIS SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of July 1, 1999, by and between Timothy M. Jones, an individual residing at 1165 Park Avenue, Apt. 7D, New York, New York 10128 ("Executive"), and Mack-Cali Realty Corporation, a Maryland corporation with offices at 11 Commerce Drive, Cranford, New Jersey 07016 (the "Company").

RECITALS

WHEREAS, Executive has served as Executive Vice President of the Company pursuant to his prior employment agreement dated as of December 1997 (the "Prior Agreement") entered into as of the closing of the combination of Cali Realty Corporation with the Mack Companies (the "Mack Combination");

WHEREAS, Executive was appointed President of the Company on April 18, 1999;

WHEREAS, the Company and the Executive wish to amend and restate the Prior Agreement in its entirety among other things to acknowledge Executive's appointment as President, to provide for an award of Restricted Shares and a Tax Gross-Up Payment (as defined in sub-paragraph 4(c) below), to change the Employment Period (as defined in sub-paragraph 2(a) below) to (4) years and to amend the amount of the severance payment Executive may be eligible to receive upon termination of employment with the Company; and

WHEREAS, the Company desires to continue to employ Executive as President and Executive desires to continue to be employed by the Company as President,


pursuant to the amended and restated terms set forth herein and to restate the Prior Agreement in its entirety

NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:

1. Employment.

The Company hereby agrees to employ Executive, and Executive hereby agrees to accept such employment during the period and upon the terms and conditions set forth in this Agreement.

2. Employment Period.

(a) Except as otherwise provided in this Agreement to the contrary, the terms and conditions of this Agreement shall be and remain in effect during the period of employment (the "Employment Period") established under this Paragraph 2. The initial Employment Period shall be for a term commencing on the date of this Agreement and ending on the fourth anniversary of the date of this Agreement provided, however, that commencing on the day after the date of this Agreement and on each day thereafter, the Employment Period shall be extended for one additional day so that a constant four (4) year Employment Period shall be in effect, unless (i) the Company or Executive elects not to extend the term of this Agreement by giving written notice to the other party in accordance with Paragraph 19, in which case, subject to the provisions of sub-paragraph 5(a)(iv) below, the term of this Agreement shall become fixed and shall end on the fourth anniversary of the date of such written notice ("Notice of Non-Renewal"), or
(ii) Executive's employment terminates hereunder.

2

(b) Notwithstanding anything contained herein to the contrary: (i) Executive's employment with the Company may be terminated by the Company or Executive during the Employment Period, subject to the terms and conditions of this Agreement; and (ii) nothing in this Agreement shall mandate or prohibit a continuation of Executive's employment following the expiration of the Employment Period upon such terms and conditions as the Board of Directors of the Company (the "Board") and Executive may mutually agree.

(c) If Executive's employment with the Company is terminated, for purposes of this Agreement the term "Unexpired Employment Period" shall mean the period commencing on the date of such termination and ending on the last day of the Employment Period.

3. Services / Place of Employment.

(a) Services. During the Employment Period, Executive shall hold the position of President of the Company. Executive shall devote his best efforts and substantially all of his business time, skill and attention to the business of the Company (other than absences due to vacation, illness, disability or approved leave of absence), and shall perform such duties as are customarily performed by similar executive officers and as may be more specifically enumerated from time to time by the Chief Executive Officer; provided, however, that the foregoing is not intended to (a) preclude Executive from (i) owning and managing personal investments, including real estate investments, subject to the restrictions set forth in Paragraph 13 hereof or (ii) engaging in charitable activities and community affairs, or (b) restrict or otherwise limit Executive from

3

conducting the activities described in Schedule A, attached hereto, (the "Excluded Activities"), provided that the performance of the activities referred to in clauses (a) and (b) does not prevent Executive from devoting substantially all of his business time to the Company.

(b) Place of Employment. The principal place of employment of Executive shall be at the Company's principal executive offices in Cranford, New Jersey.

4. Compensation and Benefits.

(a) Salary. During the Employment Period, the Company shall pay Executive a minimum annual base salary in the amount of $515,000 (the "Annual Base Salary") payable in accordance with the Company's regular payroll practices. Executive's Annual Base Salary shall be reviewed annually in accordance with the policy of the Company from time to time and may be subject to upward adjustment based upon, among other things, Executive's performance, as determined in the sole discretion of the Chief Executive Officer. In no event shall Executive's Annual Base Salary in effect at a particular time be reduced without his prior written consent.

(b) Incentive Compensation/Bonuses. In addition, Executive shall be eligible for incentive compensation payable each year in such amounts as may be determined by the Option and Executive Compensation Committee of the Board (the "Compensation Committee"). Executive shall be entitled to receive such bonuses, restricted share awards and options to purchase shares of common stock, par value $0.01 per share, of the Company (the "Common Stock") as the Board or the

4

Compensation Committee as the case may be shall approve, in its sole discretion, including, without limitation, options, restricted share awards and bonuses contingent upon Executive's performance and the achievement of specified financial and operating objectives.

(c) Restricted Share Award/Tax Gross-Up Payment. Pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 1, 1998 (the "SOP"), Executive has been awarded a restricted share award of 37,500 shares of Common Stock ("Restricted Shares") as of July 1, 1999 (the "Restricted Share Award"). Executive shall be entitled to receive a tax gross-up payment (the "Tax Gross-Up Payment") from the Company with respect to each tax year in which Restricted Shares granted pursuant to the Restricted Share Award vest and are distributed to him. Each Tax Gross-Up Payment shall be a dollar amount equal to forty-three (43%) percent of the fair market value of the Restricted Shares at time of vesting, exclusive of dividends. In the event vesting occurs with respect to any Restricted Shares as a result of the achievement of the required performance goals, such payment shall be made as soon as practicable after a determination that the performance goals have been achieved but in no event later than the 90th day of the fiscal year of the Company immediately following the fiscal year as to which the performance goals were achieved. In the event vesting occurs for any other reason, including, without limitation, termination of Executive's employment by the Company without Cause or by Executive for Good Reason (but excluding a termination by the Company for Cause or a voluntary quit without Good Reason by Executive), such payment shall be made as soon as

5

practicable after the date of vesting but in no event later than the tenth
(10th) business day following such vesting.

(d) Taxes and Withholding. The Company shall have the right to deduct and withhold from all compensation all social security and other federal, state and local taxes and charges which currently are or which hereafter may be required by law to be so deducted and withheld.

(e) Additional Benefits. In addition to the compensation specified above and other benefits provided pursuant to this Paragraph 4, Executive shall be entitled to the following benefits:

(i) participation in the SOP, the Mack-Cali Realty Corporation
401(k) Savings and Retirement Plan (subject to statutory rules and maximum contributions and non-discrimination requirements applicable to 401(k) plans) and such other benefit plans and programs, including but not limited to restricted stock, phantom stock and/or unit awards, loan programs and any other incentive compensation plans or programs (whether or not employee benefit plans or programs), as maintained by the Company from time to time and made generally available to executives of the Company with such participation to be consistent with reasonable Company guidelines;

(ii) participation in any health insurance, disability insurance, paid vacation, group life insurance or other welfare benefit program made generally available to executives of the Company; and

(iii) reimbursement for reasonable business expenses incurred by Executive in furtherance of the interests of the Company including a monthly allowance of twelve hundred ($1,200) which is intended to cover the cost of local business-related travel expenses exclusive of amounts paid to third-parties (e.g. taxi service).

5. Termination of Employment and Change in Control.

6

(a) Executive's employment hereunder may be terminated during the Employment Period under the following circumstances:

(i) Cause. The Company shall have the right to terminate Executive's employment for Cause upon Executive's: (A) willful and continued failure to use best efforts to substantially perform his duties hereunder (other than any such failure resulting from Executive's incapacity due to physical or mental illness) for a period of thirty (30) days after written demand for substantial performance is delivered by the Company specifically identifying the manner in which the Company believes Executive has not substantially performed his duties; (B) willful misconduct and/or willful violation of Paragraph 11 hereof, which is materially economically injurious to the Company and the Partnership taken as a whole; (C) the willful violation of the provisions of Paragraph 13 hereof; or (D) conviction of, or plea of guilty to a felony. For purposes of this sub-paragraph 5(a), no act, or failure to act, on Executive's part shall be considered "willful" unless done, or omitted to be done, by him (I) not in good faith and (II) without reasonable belief that his action or omission was in furtherance of the interests of the Company.

(ii) Death. Executive's employment hereunder shall terminate upon his death.

(iii) Disability. The Company shall have the right to terminate Executive's employment due to "Disability" in the event that there is a determination by the Company, upon the advice of an independent qualified physician, reasonably acceptable to Executive, that Executive has become physically or mentally incapable of performing his duties under this Agreement and such disability has disabled Executive for a cumulative period of one hundred eighty (180) days within a twelve (12) month period.

(iv) Good Reason. Executive shall have the right to terminate his employment for "Good Reason": (A) upon the occurrence of any material breach of this Agreement by the Company which shall include but not be limited to; an assignment to Executive of duties materially and adversely inconsistent with Executive's status as President or a material or adverse alteration in the nature of or diminution in Executive's duties and/or responsibilities, reporting obligations, titles or authority; (B) upon a reduction in Executive's Annual Base Salary or a material reduction in other benefits (except for bonuses or similar discretionary payments) as in effect at the time in question, a failure to pay such amounts when due or

7

any other failure by the Company to comply with Paragraph 4 hereof; (C) on or within six (6) months following the date a Notice of Non-Renewal is issued by the Company pursuant to Paragraph 2 hereof; (D) on or within six (6) months following a Change in Control (as hereinafter defined) in accordance with the provisions set forth in sub-paragraph 5(a)(vii) hereof; (E) upon any purported termination of Executive's employment for Cause which is not effected pursuant to the procedures of sub-paragraph 5(a)(i) (and for purposes of this Agreement, in the event of such failure to comply, no such purported termination shall be effective); or (F) upon the relocation of the Company's principal executive offices or Executive's own office location to a location more than thirty
(30) miles away from Cranford, New Jersey.

(v) Without Cause. The Company shall have the right to terminate the Executive's employment hereunder without Cause subject to the terms and conditions of this Agreement.

(vi) Without Good Reason. The Executive shall have the right to terminate his employment hereunder without Good Reason subject to the terms and conditions of this Agreement.

(vii) Change in Control. Executive shall have the right to terminate his employment hereunder on or within six (6) months following a Change in Control. Such termination shall be deemed a termination for Good Reason hereunder. For purposes of this Agreement "Change in Control" shall mean that any of the following events has occurred: (A) any "person" or "group" of persons, as such terms are used in Sections 13 and 14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than any employee benefit plan sponsored by the Company, becomes the "beneficial owner", as such term is used in Section 13 of the Exchange Act, (irrespective of any vesting or waiting periods) of (I) Common Stock or any class of stock convertible into Common Stock and/or (II) Common OP Units or preferred units or any other class of units convertible into Common OP Units, in an amount equal to twenty (20%) percent or more of the sum total of the Common Stock and the Common OP Units (treating all classes of outstanding stock, units or other securities convertible into stock units as if they were converted into Common Stock or Common OP Units as the case may be and then treating Common Stock and Common OP Units as if they were a single class) issued and outstanding immediately prior to such acquisition as if they were a single class and disregarding any equity raise in connection with the financing of such transaction; (B) any Common Stock is

8

purchased pursuant to a tender or exchange offer other than an offer by the Company; (C) the dissolution or liquidation of the Company or the consummation of any merger or consolidation of the Company or any sale or other disposition of all or substantially all of its assets, if the shareholders of the Company and unitholders of the Partnership taken as a whole and considered as one class immediately before such transaction own, immediately after consummation of such transaction, equity securities and partnership units possessing less than fifty (50%) percent of the surviving or acquiring company and partnership taken as a whole; or (D) a turnover, during any two (2) year period, of the majority of the members of the Board, without the consent of the remaining members of the Board as to the appointment of the new Board members.

(b) Notice of Termination. Any termination of Executive's employment by the Company or any such termination by Executive (other than on account of death) shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive's employment under the provision so indicated. In the event of the termination of Executive's employment on account of death, written Notice of Termination shall be deemed to have been provided on the date of death.

6. Compensation Upon Termination of Employment By the Company for Cause or By Executive without Good Reason.

In the event the Company terminates Executive's employment for Cause or Executive terminates his employment without Good Reason, the Company shall pay Executive any unpaid Annual Base Salary at the rate then in effect accrued through and including the date of termination. In addition, in such event, Executive shall be entitled

9

(i) to receive any earned but unpaid incentive compensation or bonuses and (ii) to exercise any options which have vested and are exercisable in accordance with the terms of the applicable option grant agreement or plan, and (iii) to retain and/or receive any Restricted Shares which have vested as of the last day of the Company's fiscal year coincident or immediately preceding Executive's termination of employment and the corresponding Tax Gross-Up Payment (irrespective of whether the determination is made after Executive's termination of employment).

Except for any rights which Executive may have to unpaid salary amounts through and including the date of termination, earned but unpaid incentive compensation or bonuses, vested options, vested Restricted Shares and the corresponding Tax Gross-Up Payment, the Company shall have no further obligations hereunder following such termination. The aforesaid amounts shall be payable in full immediately upon such termination.

7. Compensation Upon Termination of Employment Upon Death or Disability.

In the event of termination of Executive's employment as a result of either Executive's death or Disability, the Company shall pay to Executive, his estate or his personal representative the aggregate of (i) a cash payment of two million seven hundred thousand dollars ($2,700,000) in full immediately upon such termination (the "Fixed Amount") and (ii) reimbursement of expenses incurred prior to date of termination ("Expense Reimbursement"). Executive (and Executive's dependents) shall also receive continuation of health coverage through the end of the Unexpired Employment Period on the same basis as health coverage is provided by the Company

10

for active employees and as may be amended from time to time ("Medical Continuation").

In addition, all (A) incentive compensation payments or programs of any nature whether stock based or otherwise that are subject to a vesting schedule including, without limitation, the Restricted Share Award or any other restricted stock, phantom stock, units and any loan forgiveness arrangements granted to Executive ("Incentive Compensation") shall immediately vest as of the date of such termination ("Vested Incentive Compensation"), (B) options granted to Executive shall immediately vest as of the date of such termination (the "Vested Options") and Executive shall be entitled at the option of Executive, his estate or his personal representative, within one (1) year of the date of such termination, to exercise the Vested Options and/or other options which have vested (including, without limitation, all other options which have previously vested in accordance with the Prior Agreement, any applicable option grant agreement or plan) (the "Total Vested Options") and are exercisable in accordance with the terms of the applicable option grant agreement or plan and/or any other methods or procedures for exercise applicable to optionees or to require the Company (upon written notice delivered within one hundred eighty
(180) days following the date of Executive's termination) to repurchase all or any portion of Executive's vested options to purchase shares of Common Stock at a price equal to the difference between the Repurchase Fair Market Value (as hereinafter defined) of the shares of Common Stock for which the options to be repurchased are exercisable and the exercise price of such options as of the date of Executive's termination of employment (the "Vested Option Exercise Election"), and (C) the Tax Gross-Up Payment(s) applicable to the Restricted Share

11

Award shall vest and be paid to Executive at such time as provided in sub-paragraph 4(c) above (the "Vested Tax Gross-Up Payments"). In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

Except for any rights which Executive or Executive's estate in the event of Executive's death may have to all of the above including the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation (which, in the event of Executive's death, shall be provided to Executive's dependents), the Company shall have no further obligations hereunder following such termination.

For purposes of this Agreement, "Repurchase Fair Market Value" shall mean the average of the closing price on the New York Stock Exchange (or such other exchange on which the Common Stock is primarily traded) of the Common Stock on each of the trading days within the thirty (30) days immediately preceding the date of termination of Executive's employment.

8. Compensation Upon Termination of Employment By the Company Without Cause or By Executive for Good Reason.

In the event the Company terminates Executive's employment for any reason other than Cause or Executive terminates his employment for Good Reason, the Company shall pay to Executive and Executive shall be entitled to receive the aggregate of (i) the Fixed Amount and (ii) Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment,

12

Expense Reimbursement and Medical Continuation. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control. Executive understands that any options exercised more than ninety (90) days following the date of his termination of employment which were granted as incentive stock options shall automatically be converted into non-qualified options.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation, the Company shall have no further obligations hereunder following such termination. The parties both agree that the agreement to make these payments was consideration and an inducement to obtain Executive's consent to enter into this Agreement. The payments are not a penalty and neither party will claim them to be a penalty. Rather, the payments represent a fair approximation of reasonable amounts due to Executive for the Employment Period.

9. Change in Control.

(a) Options. Any Incentive Compensation and options granted to Executive that have not vested as of the date of a Change in Control shall immediately vest upon the date of the Change in Control. Neither the occurrence of a Change in Control, nor the vesting in any options as a result thereof shall require Executive to exercise any options. In the event of a conflict between any Incentive Compensation

13

grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

(b) Upon Termination. In the event Executive terminates his employment on or following a Change in Control as set forth in sub-paragraph
5(a)(vii), the Company shall pay to Executive and Executive shall be entitled to all the payments and rights Executive would have had if Executive had terminated his employment with Good Reason as set forth in Paragraph 8.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options (including, without limitation, by acceleration in accordance with sub-paragraph 9(a)) and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement, Medical Continuation and the Excise Tax Gross Up set forth in subparagraph 9(c), the Company shall have no further obligations hereunder following such termination.

(c) Excise Tax Gross Up. In addition, if it is determined by an independent accountant mutually acceptable to the Company and Executive that as a result of any payment in the nature of compensation made by the Company to (or for the benefit of) Executive pursuant to this Agreement or otherwise, an excise tax may be imposed on Executive pursuant to Section 4999 of the Code (or any successor provisions), the Company shall pay Executive in cash an amount equal to X determined under the following formula: (the "Excise Tax Gross Up"):

E x P

X = --------------------------------

1-[(FI x (1-SLI)) + SLI + E + M]

where

14

E     =     the rate at which the excise tax is assessed under
            Section 4999 of the Code (or any successor provisions);

P     =     the amount with respect to which such excise tax is
            assessed, determined without regard to the Excise Tax
            Gross Up;

FI    =     the highest effective marginal rate of income tax
            applicable to Executive under the Code for the taxable
            year in question (taking into account any phase-out or
            loss of deductions, personal exemptions or other similar
            adjustments);

SLI   =     the sum of the highest effective marginal rates of
            income tax applicable to Executive under all applicable
            state and local laws for the taxable year in question
            (taking into account any phase-out or loss of
            deductions, personal exemptions and other similar
            adjustments); and

M     =     the highest marginal rate of Medicare tax applicable to
            Executive under the Code for the taxable year in
            question.

With respect to any payment in the nature of compensation that is made to (or for the benefit of) Executive under the terms of this Agreement or otherwise and on which an excise tax under Section 4999 of the Code (or any successor provisions) may be assessed, the payment determined under this sub-paragraph 9(c) shall be paid to Executive at the time of the Change in Control but prior to the consummation of the transaction with any successor. It is the intention of the parties that the Company provide Executive with a full tax gross-up under the provisions of this sub-paragraph, so that on a net after-tax basis, the result to Executive shall be the same as if the excise tax under Section 4999 of the Code (or any successor provisions) had not been imposed. The Excise Tax Gross Up may be adjusted if alternative minimum tax rules are applicable to Executive.

15

10. Mitigation / Effect on Employee Benefit Plans and Programs.

(a) Mitigation. Executive shall not be required to mitigate amounts payable under this Agreement by seeking other employment or otherwise, and there shall be no offset against amounts due Executive under this Agreement on account of subsequent employment. Amounts owed to Executive under this Agreement shall not be offset by any claims the Company may have against Executive and such payment shall not be affected by any other circumstances, including, without limitation, any counterclaim, recoupment, defense, or other right which the Company may have against Executive or others.

(b) Effect on Employee Benefit Programs. The termination of Executive's employment hereunder, whether by the Company or Executive, shall have no effect on the rights and obligations of the parties hereto under the Company's (i) welfare benefit plans including, without limitation, Medical Continuation as provided for herein and, health coverage thereafter but only to the extent required by law, and on the same basis applicable to other employees and (ii) 401(k) Plan but only to the extent required by law and pursuant to the terms of the 401(k) Plan.

11. Confidential Information.

(a) Executive understands and acknowledges that during his employment with the Company, he will be exposed to Confidential Information (as defined below), all of which is proprietary and which will rightfully belong to the Company. Executive shall hold in a fiduciary capacity for the benefit of the Company such Confidential Information obtained by Executive during his employment with the

16

Company and shall not, directly or indirectly, at any time, either during or after his employment with the Company, without the Company's prior written consent, use any of such Confidential Information or disclose any of such Confidential Information to any individual or entity other than the Company or its employees, attorneys, accountants, financial advisors, consultants, or investment bankers except as required in the performance of his duties for the Company or as otherwise required by law. Executive shall take all reasonable steps to safeguard such Confidential Information and to protect such Confidential Information against disclosure, misuse, loss or theft.

(b) The term "Confidential Information" shall mean any information not generally known in the relevant trade or industry or otherwise not generally available to the public, which was obtained from the Company or its predecessors or which was learned, discovered, developed, conceived, originated or prepared during or as a result of the performance of any services by Executive on behalf of the Company or its predecessors. For purposes of this Paragraph 11, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

12. Return of Documents.

Except for such items which are of a personal nature to Executive (e.g., daily business planner), all writings, records, and other documents and things containing any Confidential Information shall be the exclusive property of the Company, shall not be copied, summarized, extracted from, or removed from the premises of the Company,

17

except in pursuit of the business of the Company and at the direction of the Company, and shall be delivered to the Company, without retaining any copies, upon the termination of Executive's employment or at any time as requested by the Company.

13. Noncompete. Executive agrees that:

(a) During the Employment Period and, in the event (i) the Company terminates Executive's employment for Cause, or (ii) Executive terminates his employment without Good Reason, for a one (1) year period thereafter, Executive shall not, directly or indirectly, within the continental United States, engage in, or own, invest in, manage or control any venture or enterprise primarily engaged in any office-service, flex, or office property development, acquisition or management activities without regard to whether or not such activities compete with the Company. Nothing herein shall prohibit Executive from being a passive owner of not more than five percent (5%) of the outstanding stock of any class of securities of a corporation or other entity engaged in such business which is publicly traded, so long as he has no active participation in the business of such corporation or other entity. Moreover, the foregoing limitations shall not be deemed to restrict or otherwise limit Executive from conducting the Excluded Activities, if any, provided that during the Employment Period the performance of such activities does not prevent Executive from devoting substantially all of his business time to the Company.

(b) If, at the time of enforcement of this Paragraph 13, a court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable,

18

the parties agree that reasonable maximum duration, scope, area or other restrictions may be substituted by such court for the stated duration, scope, area or other restrictions and upon substitution by such court, this Agreement shall be automatically modified without further action by the parties hereto.

(c) For purposes of this Paragraph 13, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

14. Remedies.

The parties hereto agree that the Company would suffer irreparable harm from a breach by Executive of any of the covenants or agreements contained in Paragraphs 11, 12 or 13 of this Agreement. Therefore, in the event of the actual or threatened breach by Executive of any of the provisions of Paragraphs 11, 12 or 13 of this Agreement, the Company may, in addition and supplementary to other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violation of the provisions thereof.

15. Indemnification/Legal Fees.

(a) Indemnification. In the event the Executive is made party or threatened to be made a party to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "Proceeding"), by reason of Executive's employment

19

with or serving as an officer or director of the Company, whether or not the basis of such Proceeding is alleged action in an official capacity, the Company shall indemnify, hold harmless and defend Executive to the fullest extent authorized by Maryland law, as the same exists and may hereafter be amended, against any and all claims, demands, suits, judgments, assessments and settlements including all expenses incurred or suffered by Executive in connection therewith (including, without limitation, all legal fees incurred using counsel reasonably acceptable to Executive) and such indemnification shall continue as to Executive even after Executive is no longer employed by the Company and shall inure to the benefit of his heirs, executors, and administrators. Expenses incurred by Executive in connection with any Proceeding shall be paid by the Company in advance upon request of Executive that the Company pay such expenses; but, only in the event that Executive shall have delivered in writing to the Company an undertaking to reimburse the Company for expenses with respect to which Executive is not entitled to indemnification. The provisions of this Paragraph shall remain in effect after this Agreement is terminated irrespective of the reasons for termination. The indemnification provisions of this Paragraph shall not supersede or reduce any indemnification provided to Executive under any separate agreement, or the by-laws of the Company since it is intended that this Agreement shall expand and extend the Executive's rights to receive indemnity.

(b) Legal Fees. If any contest or dispute shall arise between the Company and Executive regarding or as a result of any provision of this Agreement, the Company shall reimburse Executive for all legal fees and expenses reasonably incurred by Executive in connection with such contest or dispute, but only if Executive is

20

successful in respect of substantially all of Executive's claims pursued or defended in connection with such contest or dispute. Such reimbursement shall be made as soon as practicable following the resolution of such contest or dispute (whether or not appealed).

16. Successors and Assigns.

(a) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance satisfactory to Executive, to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such agreement prior to the effectiveness of an such succession shall be a breach of this Agreement and shall entitle Executive to compensation from the Company in the same amount and on the same terms as he would be entitled to hereunder if Executive terminated his employment hereunder within six (6) months of a Change in Control as set forth in Paragraph 9, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the date of termination. In the event of such a breach of this Agreement, the Notice of Termination shall specify such date as the date of termination. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to all or substantially all of its business and/or its assets as aforesaid which executes and delivers the agreement provided for in this Paragraph 16 or which otherwise becomes

21

bound by all the terms and provisions of this Agreement by operation of law. Any cash payments owed to Executive pursuant to this Paragraph 16 shall be paid to Executive in a single sum without discount for early payment immediately prior to the consummation of the transaction with such successor.

(b) This Agreement and all rights of Executive hereunder may be transferred only by will or the laws of descent and distribution. Upon Executive's death, this Agreement and all rights of Executive hereunder shall inure to the benefit of and be enforceable by Executive's beneficiary or beneficiaries, personal or legal representatives, or estate, to the extent any such person succeeds to Executive's interests under this Agreement. Executive shall be entitled to select and change a beneficiary or beneficiaries to receive any benefit or compensation payable hereunder following Executive's death by giving Company written notice thereof. If Executive should die following the date of termination while any amounts would still be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons so appointed in writing by Executive, including, without limitation, under any applicable plan, or otherwise to his legal representatives or estate.

17. Timing of and No Duplication of Payments.

All payments payable to Executive pursuant to this Agreement shall be paid as soon as practicable after such amounts have become fully vested and determinable. In addition, Executive shall not be entitled to receive duplicate payments under any of the provisions of this Agreement.

22

18. Modification or Waiver.

No amendment, modification, waiver, termination or cancellation of this Agreement shall be binding or effective for any purpose unless it is made in a writing signed by the party against whom enforcement of such amendment, modification, waiver, termination or cancellation is sought. No course of dealing between or among the parties to this Agreement shall be deemed to affect or to modify, amend or discharge any provision or term of this Agreement. No delay on the part of the Company or Executive in the exercise of any of their respective rights or remedies shall operate as a waiver thereof, and no single or partial exercise by the Company or Executive of any such right or remedy shall preclude other or further exercise thereof. A waiver of right or remedy on any one occasion shall not be construed as a bar to or waiver of any such right or remedy on any other occasion.

The respective rights and obligations of the parties hereunder shall survive the Executive's termination of employment and termination of this Agreement to the extent necessary for the intended preservation of such rights and obligations.

19. Notices.

All notices or other communications required or permitted hereunder shall be made in writing and shall be deemed to have been duly given if delivered by hand or delivered by a recognized delivery service or mailed, postage prepaid, by express, certified or registered mail, return receipt requested, and addressed to the Chief Executive Officer of the Company or Executive, as applicable, at the address set forth above (or to such

23

other address as shall have been previously provided in accordance with this Paragraph 19).

20. Governing Law.

This agreement will be governed by and construed in accordance with the laws of the State of New Jersey except as to Paragraph 15(a), without regard to principles of conflicts of laws thereunder.

21. Severability.

Whenever possible, each provision and term of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or term of this Agreement shall be held to be prohibited by or invalid under such applicable law, then, subject to the provisions of sub-paragraph 13(b) above, such provision or term shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or affecting in any manner whatsoever the remainder of such provisions or term or the remaining provisions or terms of this Agreement.

22. Legal Representation.

Each of the Company and Executive have been represented by counsel with respect to this Agreement.

23. Counterparts.

This Agreement may be executed in separate counterparts, each of which is deemed to be an original and both of which taken together shall constitute one and the same agreement.

24

24. Headings.

The headings of the Paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute a part hereof and shall not affect the construction or interpretation of this Agreement.

25. Entire Agreement.

This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all other prior agreements and undertakings, both written and oral, among the parties with respect to the subject matter hereof. The parties recognize that the Prior Agreement has been amended and restated in its entirety by this Agreement and the terms of the Prior Agreement are of no further force and effect.

26. Survival of Agreements.

The covenants made in Paragraphs 5 through 15 and 21 each shall survive the termination of this Agreement.

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the date first above written.

JOHN R. CALI

AMENDED AND RESTATED EMPLOYMENT AGREEMENT

THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of July 1, 1999, by and between John R. Cali, an individual residing at 203 Laurel Hill Road, Mountain Lakes, New Jersey 07046 ("Executive"), and Mack-Cali Realty Corporation, a Maryland corporation with offices at 11 Commerce Drive, Cranford, New Jersey 07016 (the "Company").

RECITALS

WHEREAS, Executive has served as Chief Administrative Officer of the Company pursuant to his prior employment agreement dated as of December 1997 (the "Prior Agreement") entered into as of the closing of the combination of Cali Realty Corporation with the Mack Companies (the "Mack Combination");

WHEREAS, the Company and the Executive wish to amend and restate the Prior Agreement in its entirety to provide for an award of Restricted Shares and a Tax Gross-Up Payment (as defined in sub-paragraph 4(c) below), to change the Employment Period (as defined in sub-paragraph 2(a) below) to (4) years and to amend the amount of the severance payment Executive may be eligible to receive upon termination of employment with the Company; and

WHEREAS, the Company desires to continue to employ Executive as Executive Vice President of Development, and Executive desires to continue to be employed by the Company as Executive Vice President of Development, pursuant to the amended and restated terms set forth herein and to restate the Prior Agreement in its entirety

NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:


1. Employment.

The Company hereby agrees to employ Executive, and Executive hereby agrees to accept such employment during the period and upon the terms and conditions set forth in this Agreement.

2. Employment Period.

(a) Except as otherwise provided in this Agreement to the contrary, the terms and conditions of this Agreement shall be and remain in effect during the period of employment (the "Employment Period") established under this Paragraph 2. The initial Employment Period shall be for a term commencing on the date of this Agreement and ending on the fourth anniversary of the date of this Agreement provided, however, that commencing on the day after the date of this Agreement and on each day thereafter, the Employment Period shall be extended for one additional day so that a constant four (4) year Employment Period shall be in effect, unless (i) the Company or Executive elects not to extend the term of this Agreement by giving written notice to the other party in accordance with Paragraph 19, in which case, subject to the provisions of sub-paragraph 5(a)(iv) below, the term of this Agreement shall become fixed and shall end on the fourth anniversary of the date of such written notice ("Notice of Non-Renewal"), or
(ii) Executive's employment terminates hereunder.

(b) Notwithstanding anything contained herein to the contrary: (i) Executive's employment with the Company may be terminated by the Company or Executive during the Employment Period, subject to the terms and conditions of this Agreement; and (ii) nothing in this Agreement shall mandate or prohibit a continuation

2

of Executive's employment following the expiration of the Employment Period upon such terms and conditions as the Board of Directors of the Company (the "Board") and Executive may mutually agree.

(c) If Executive's employment with the Company is terminated, for purposes of this Agreement the term "Unexpired Employment Period" shall mean the period commencing on the date of such termination and ending on the last day of the Employment Period.

3. Services / Place of Employment.

(a) Services. During the Employment Period, Executive shall hold the position of Executive Vice President of Development of the Company. Executive shall devote his best efforts and substantially all of his business time, skill and attention to the business of the Company (other than absences due to vacation, illness, disability or approved leave of absence), and shall perform such duties as are customarily performed by similar executive officers and as may be more specifically enumerated from time to time by the Chief Executive Officer; provided, however, that the foregoing is not intended to (a) preclude Executive from (i) owning and managing personal investments, including real estate investments, subject to the restrictions set forth in Paragraph 13 hereof or (ii) engaging in charitable activities and community affairs, or (b) restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to those properties described in Schedule A, attached hereto, (the "Excluded Properties"), provided that the

3

performance of the activities referred to in clauses (a) and (b) does not prevent Executive from devoting substantially all of his business time to the Company.

(b) Place of Employment. The principal place of employment of Executive shall be at the Company's principal executive offices in Cranford, New Jersey.

4. Compensation and Benefits.

(a) Salary. During the Employment Period, the Company shall pay Executive a minimum annual base salary in the amount of $325,000 (the "Annual Base Salary") payable in accordance with the Company's regular payroll practices. Executive's Annual Base Salary shall be reviewed annually in accordance with the policy of the Company from time to time and may be subject to upward adjustment based upon, among other things, Executive's performance, as determined in the sole discretion of the Chief Executive Officer. In no event shall Executive's Annual Base Salary in effect at a particular time be reduced without his prior written consent.

(b) Incentive Compensation/Bonuses. In addition, Executive shall be eligible for incentive compensation payable each year in such amounts as may be determined by the Option and Executive Compensation Committee of the Board (the "Compensation Committee"). Executive shall be entitled to receive such bonuses, restricted share awards and options to purchase shares of common stock, par value $0.01 per share, of the Company (the "Common Stock") as the Board or the Compensation Committee as the case may be shall approve, in its sole discretion, including, without limitation, options, restricted share awards and bonuses contingent

4

upon Executive's performance and the achievement of specified financial and operating objectives.

(c) Restricted Share Award/Tax Gross-Up Payment. Pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 1, 1998 (the "SOP"), Executive has been awarded a restricted share award of 22,031 shares of Common Stock ("Restricted Shares") as of July 1, 1999 (the "Restricted Share Award"). Executive shall be entitled to receive a tax gross-up payment (the "Tax Gross-Up Payment") from the Company with respect to each tax year in which Restricted Shares granted pursuant to the Restricted Share Award vest and are distributed to him. Each Tax Gross-Up Payment shall be a dollar amount equal to forty-three (43%) percent of the fair market value of the Restricted Shares at time of vesting, exclusive of dividends. In the event vesting occurs with respect to any Restricted Shares as a result of the achievement of the required performance goals, such payment shall be made as soon as practicable after a determination that the performance goals have been achieved but in no event later than the 90th day of the fiscal year of the Company immediately following the fiscal year as to which the performance goals were achieved. In the event vesting occurs for any other reason, including, without limitation, termination of Executive's employment by the Company without Cause or by Executive for Good Reason (but excluding a termination by the Company for Cause or a voluntary quit without Good Reason by Executive), such payment shall be made as soon as practicable after the date of vesting but in no event later than the tenth
(10th) business day following such vesting.

5

(d) Taxes and Withholding. The Company shall have the right to deduct and withhold from all compensation all social security and other federal, state and local taxes and charges which currently are or which hereafter may be required by law to be so deducted and withheld.

(e) Additional Benefits. In addition to the compensation specified above and other benefits provided pursuant to this Paragraph 4, Executive shall be entitled to the following benefits:

(i) participation in the SOP, the Mack-Cali Realty Corporation
401(k) Savings and Retirement Plan (subject to statutory rules and maximum contributions and non-discrimination requirements applicable to 401(k) plans) and such other benefit plans and programs, including but not limited to restricted stock, phantom stock and/or unit awards, loan programs and any other incentive compensation plans or programs (whether or not employee benefit plans or programs), as maintained by the Company from time to time and made generally available to executives of the Company with such participation to be consistent with reasonable Company guidelines;

(ii) participation in any health insurance, disability insurance, paid vacation, group life insurance or other welfare benefit program made generally available to executives of the Company; and

(iii) reimbursement for reasonable business expenses incurred by Executive in furtherance of the interests of the Company including a monthly allowance of twelve hundred ($1,200) which is intended to cover the cost of local business-related travel expenses exclusive of amounts paid to third-parties (e.g. taxi service).

5. Termination of Employment and Change in Control.

(a) Executive's employment hereunder may be terminated during the Employment Period under the following circumstances:

(i) Cause. The Company shall have the right to terminate Executive's employment for Cause upon Executive's: (A) willful and continued

6

failure to use best efforts to substantially perform his duties hereunder (other than any such failure resulting from Executive's incapacity due to physical or mental illness) for a period of thirty (30) days after written demand for substantial performance is delivered by the Company specifically identifying the manner in which the Company believes Executive has not substantially performed his duties; (B) willful misconduct and/or willful violation of Paragraph 11 hereof, which is materially economically injurious to the Company and the Partnership taken as a whole; (C) the willful violation of the provisions of Paragraph 13 hereof; or (D) conviction of, or plea of guilty to a felony. For purposes of this sub-paragraph 5(a), no act, or failure to act, on Executive's part shall be considered "willful" unless done, or omitted to be done, by him (I) not in good faith and (II) without reasonable belief that his action or omission was in furtherance of the interests of the Company.

(ii) Death. Executive's employment hereunder shall terminate upon his death.

(iii) Disability. The Company shall have the right to terminate Executive's employment due to "Disability" in the event that there is a determination by the Company, upon the advice of an independent qualified physician, reasonably acceptable to Executive, that Executive has become physically or mentally incapable of performing his duties under this Agreement and such disability has disabled Executive for a cumulative period of one hundred eighty (180) days within a twelve (12) month period.

(iv) Good Reason. Executive shall have the right to terminate his employment for "Good Reason": (A) upon the occurrence of any material breach of this Agreement by the Company which shall include but not be limited to; an assignment to Executive of duties materially and adversely inconsistent with Executive's status as Executive Vice President of Development or a material or adverse alteration in the nature of or diminution in Executive's duties and/or responsibilities, reporting obligations, titles or authority; (B) upon a reduction in Executive's Annual Base Salary or a material reduction in other benefits (except for bonuses or similar discretionary payments) as in effect at the time in question, a failure to pay such amounts when due or any other failure by the Company to comply with Paragraph 4 hereof; (C) on or within six (6) months following the date a Notice of Non-Renewal is issued by the Company pursuant to Paragraph 2 hereof; (D) on or within six (6) months following a Change in Control (as hereinafter defined) in accordance with the provisions set forth in sub-paragraph 5(a)(vii)

7

hereof; (E) upon any purported termination of Executive's employment for Cause which is not effected pursuant to the procedures of sub-paragraph 5(a)(i) (and for purposes of this Agreement, in the event of such failure to comply, no such purported termination shall be effective); or (F) upon the relocation of the Company's principal executive offices or Executive's own office location to a location more than thirty
(30) miles away from Cranford, New Jersey.

(v) Without Cause. The Company shall have the right to terminate the Executive's employment hereunder without Cause subject to the terms and conditions of this Agreement.

(vi) Without Good Reason. The Executive shall have the right to terminate his employment hereunder without Good Reason subject to the terms and conditions of this Agreement.

(vii) Change in Control. Executive shall have the right to terminate his employment hereunder on or within six (6) months following a Change in Control. Such termination shall be deemed a termination for Good Reason hereunder. For purposes of this Agreement "Change in Control" shall mean that any of the following events has occurred: (A) any "person" or "group" of persons, as such terms are used in Sections 13 and 14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than any employee benefit plan sponsored by the Company, becomes the "beneficial owner", as such term is used in Section 13 of the Exchange Act, (irrespective of any vesting or waiting periods) of (I) Common Stock or any class of stock convertible into Common Stock and/or (II) Common OP Units or preferred units or any other class of units convertible into Common OP Units, in an amount equal to twenty (20%) percent or more of the sum total of the Common Stock and the Common OP Units (treating all classes of outstanding stock, units or other securities convertible into stock units as if they were converted into Common Stock or Common OP Units as the case may be and then treating Common Stock and Common OP Units as if they were a single class) issued and outstanding immediately prior to such acquisition as if they were a single class and disregarding any equity raise in connection with the financing of such transaction; (B) any Common Stock is purchased pursuant to a tender or exchange offer other than an offer by the Company; (C) the dissolution or liquidation of the Company or the consummation of any merger or consolidation of the Company or any sale or other disposition of all or substantially all of its assets, if the shareholders of the Company and unitholders

8

of the Partnership taken as a whole and considered as one class immediately before such transaction own, immediately after consummation of such transaction, equity securities and partnership units possessing less than fifty (50%) percent of the surviving or acquiring company and partnership taken as a whole; or (D) a turnover, during any two (2) year period, of the majority of the members of the Board, without the consent of the remaining members of the Board as to the appointment of the new Board members.

(b) Notice of Termination. Any termination of Executive's employment by the Company or any such termination by Executive (other than on account of death) shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive's employment under the provision so indicated. In the event of the termination of Executive's employment on account of death, written Notice of Termination shall be deemed to have been provided on the date of death.

6. Compensation Upon Termination of Employment By the Company for Cause or By Executive without Good Reason.

In the event the Company terminates Executive's employment for Cause or Executive terminates his employment without Good Reason, the Company shall pay Executive any unpaid Annual Base Salary at the rate then in effect accrued through and including the date of termination. In addition, in such event, Executive shall be entitled (i) to receive any earned but unpaid incentive compensation or bonuses and (ii) to exercise any options which have vested and are exercisable in accordance with the

9

terms of the applicable option grant agreement or plan, and (iii) to retain and/or receive any Restricted Shares which have vested as of the last day of the Company's fiscal year coincident or immediately preceding Executive's termination of employment and the corresponding Tax Gross-Up Payment (irrespective of whether the determination is made after Executive's termination of employment).

Except for any rights which Executive may have to unpaid salary amounts through and including the date of termination, earned but unpaid incentive compensation or bonuses, vested options, vested Restricted Shares and the corresponding Tax Gross-Up Payment, the Company shall have no further obligations hereunder following such termination. The aforesaid amounts shall be payable in full immediately upon such termination.

7. Compensation Upon Termination of Employment Upon Death or Disability.

In the event of termination of Executive's employment as a result of either Executive's death or Disability, the Company shall pay to Executive, his estate or his personal representative the aggregate of (i) a cash payment of two million five hundred thousand dollars ($2,500,000) in full immediately upon such termination (the "Fixed Amount") and (ii) reimbursement of expenses incurred prior to date of termination ("Expense Reimbursement"). Executive (and Executive's dependents) shall also receive continuation of health coverage through the end of the Unexpired Employment Period on the same basis as health coverage is provided by the Company for active employees and as may be amended from time to time ("Medical Continuation").

In addition, all (A) incentive compensation payments or programs of any nature whether stock based or otherwise that are subject to a vesting schedule including, without limitation, the Restricted Share Award or any other restricted stock, phantom stock, units and any loan forgiveness arrangements granted to Executive ("Incentive Compensation") shall immediately vest as of the date of such termination ("Vested Incentive Compensation"), (B) options granted to Executive shall immediately vest as of the date of such termination (the "Vested Options") and Executive shall be entitled at the option of Executive, his estate or his personal representative, within one (1) year of the date of such termination, to exercise the Vested Options and/or other options which have vested (including, without limitation, all other options which have previously vested in accordance with the Prior Agreement, any applicable option grant agreement or plan) (the "Total Vested Options") and are exercisable in accordance with the terms of the applicable option grant agreement or plan and/or any other methods or procedures for exercise applicable to optionees or to require the Company (upon written notice delivered within one hundred eighty
(180) days following the date of Executive's termination) to repurchase all or any portion of Executive's vested options to purchase shares of Common Stock at a price equal to the difference between the Repurchase Fair Market Value (as hereinafter defined) of the shares of Common Stock for which the options to be repurchased are exercisable and the exercise price of such options as of the date of Executive's termination of employment (the "Vested Option Exercise Election"), and (C) the Tax Gross-Up Payment(s) applicable to the Restricted Share Award shall vest and be paid to Executive at such time as provided in sub-paragraph 4(c) above (the "Vested Tax Gross-Up Payments"). In the event of a conflict between

11

any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

Except for any rights which Executive or Executive's estate in the event of Executive's death may have to all of the above including the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation (which, in the event of Executive's death, shall be provided to Executive's dependents), the Company shall have no further obligations hereunder following such termination.

For purposes of this Agreement, "Repurchase Fair Market Value" shall mean the average of the closing price on the New York Stock Exchange (or such other exchange on which the Common Stock is primarily traded) of the Common Stock on each of the trading days within the thirty (30) days immediately preceding the date of termination of Executive's employment.

8. Compensation Upon Termination of Employment By the Company Without Cause or By Executive for Good Reason.

In the event the Company terminates Executive's employment for any reason other than Cause or Executive terminates his employment for Good Reason, the Company shall pay to Executive and Executive shall be entitled to receive the aggregate of (i) the Fixed Amount and (ii) Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant

12

agreement or plan and this Agreement, the terms of this Agreement shall control. Executive understands that any options exercised more than ninety (90) days following the date of his termination of employment which were granted as incentive stock options shall automatically be converted into non-qualified options.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation, the Company shall have no further obligations hereunder following such termination. The parties both agree that the agreement to make these payments was consideration and an inducement to obtain Executive's consent to enter into this Agreement. The payments are not a penalty and neither party will claim them to be a penalty. Rather, the payments represent a fair approximation of reasonable amounts due to Executive for the Employment Period.

9. Change in Control.

(a) Options. Any Incentive Compensation and options granted to Executive that have not vested as of the date of a Change in Control shall immediately vest upon the date of the Change in Control. Neither the occurrence of a Change in Control, nor the vesting in any options as a result thereof shall require Executive to exercise any options. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

13

(b) Upon Termination. In the event Executive terminates his employment on or following a Change in Control as set forth in sub-paragraph
5(a)(vii), the Company shall pay to Executive and Executive shall be entitled to all the payments and rights Executive would have had if Executive had terminated his employment with Good Reason as set forth in Paragraph 8.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options (including, without limitation, by acceleration in accordance with sub-paragraph 9(a)) and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement, Medical Continuation and the Excise Tax Gross Up set forth in subparagraph 9(c), the Company shall have no further obligations hereunder following such termination.

(c) Excise Tax Gross Up. In addition, if it is determined by an independent accountant mutually acceptable to the Company and Executive that as a result of any payment in the nature of compensation made by the Company to (or for the benefit of) Executive pursuant to this Agreement or otherwise, an excise tax may be imposed on Executive pursuant to Section 4999 of the Code (or any successor provisions), the Company shall pay Executive in cash an amount equal to X determined under the following formula: (the "Excise Tax Gross Up"):

E x P
X = --------------------------------

1-[(FI x (1-SLI)) + SLI + E + M]

where

E = the rate at which the excise tax is assessed under
Section 4999 of the Code (or any successor provisions);

14

P     =     the amount with respect to which such excise tax is
            assessed, determined without regard to the Excise Tax
            Gross Up;

FI    =     the highest effective marginal rate of income tax
            applicable to Executive under the Code for the taxable
            year in question (taking into account any phase-out or
            loss of deductions, personal exemptions or other similar
            adjustments);

SLI   =     the sum of the highest effective marginal rates of
            income tax applicable to Executive under all applicable
            state and local laws for the taxable year in question
            (taking into account any phase-out or loss of
            deductions, personal exemptions and other similar
            adjustments); and

M     =     the highest marginal rate of Medicare tax applicable to
            Executive under the Code for the taxable year in
            question.

With respect to any payment in the nature of compensation that is made to (or for the benefit of) Executive under the terms of this Agreement or otherwise and on which an excise tax under Section 4999 of the Code (or any successor provisions) may be assessed, the payment determined under this sub-paragraph 9(c) shall be paid to Executive at the time of the Change in Control but prior to the consummation of the transaction with any successor. It is the intention of the parties that the Company provide Executive with a full tax gross-up under the provisions of this sub-paragraph, so that on a net after-tax basis, the result to Executive shall be the same as if the excise tax under Section 4999 of the Code (or any successor provisions) had not been imposed. The Excise Tax Gross Up may be adjusted if alternative minimum tax rules are applicable to Executive.

15

10. Mitigation / Effect on Employee Benefit Plans and Programs.

(a) Mitigation. Executive shall not be required to mitigate amounts payable under this Agreement by seeking other employment or otherwise, and there shall be no offset against amounts due Executive under this Agreement on account of subsequent employment. Amounts owed to Executive under this Agreement shall not be offset by any claims the Company may have against Executive and such payment shall not be affected by any other circumstances, including, without limitation, any counterclaim, recoupment, defense, or other right which the Company may have against Executive or others.

(b) Effect on Employee Benefit Programs. The termination of Executive's employment hereunder, whether by the Company or Executive, shall have no effect on the rights and obligations of the parties hereto under the Company's (i) welfare benefit plans including, without limitation, Medical Continuation as provided for herein and, health coverage thereafter but only to the extent required by law, and on the same basis applicable to other employees and (ii) 401(k) Plan but only to the extent required by law and pursuant to the terms of the 401(k) Plan.

11. Confidential Information.

(a) Executive understands and acknowledges that during his employment with the Company, he will be exposed to Confidential Information (as defined below), all of which is proprietary and which will rightfully belong to the Company. Executive shall hold in a fiduciary capacity for the benefit of the Company such Confidential Information obtained by Executive during his employment with the Company and shall not, directly or indirectly, at any time, either during or after his employment with the

16

Company, without the Company's prior written consent, use any of such Confidential Information or disclose any of such Confidential Information to any individual or entity other than the Company or its employees, attorneys, accountants, financial advisors, consultants, or investment bankers except as required in the performance of his duties for the Company or as otherwise required by law. Executive shall take all reasonable steps to safeguard such Confidential Information and to protect such Confidential Information against disclosure, misuse, loss or theft.

(b) The term "Confidential Information" shall mean any information not generally known in the relevant trade or industry or otherwise not generally available to the public, which was obtained from the Company or its predecessors or which was learned, discovered, developed, conceived, originated or prepared during or as a result of the performance of any services by Executive on behalf of the Company or its predecessors. For purposes of this Paragraph 11, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

12. Return of Documents.

Except for such items which are of a personal nature to Executive (e.g., daily business planner), all writings, records, and other documents and things containing any Confidential Information shall be the exclusive property of the Company, shall not be copied, summarized, extracted from, or removed from the premises of the Company, except in pursuit of the business of the Company and at the direction of the Company,

17

and shall be delivered to the Company, without retaining any copies, upon the termination of Executive's employment or at any time as requested by the Company.

13. Noncompete.

Executive agrees that:

(a) During the Employment Period and, in the event (i) the Company terminates Executive's employment for Cause, or (ii) Executive terminates his employment without Good Reason, for a one (1) year period thereafter, Executive shall not, directly or indirectly, within the continental United States, engage in, or own, invest in, manage or control any venture or enterprise primarily engaged in any office-service, flex, or office property development, acquisition or management activities without regard to whether or not such activities compete with the Company. Nothing herein shall prohibit Executive from being a passive owner of not more than five percent (5%) of the outstanding stock of any class of securities of a corporation or other entity engaged in such business which is publicly traded, so long as he has no active participation in the business of such corporation or other entity. Moreover, the foregoing limitations shall not be deemed to restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to the Excluded Properties, if any, provided that during the Employment Period the performance of such activities does not prevent Executive from devoting substantially all of his business time to the Company.

18

(b) If, at the time of enforcement of this Paragraph 13, a court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable, the parties agree that reasonable maximum duration, scope, area or other restrictions may be substituted by such court for the stated duration, scope, area or other restrictions and upon substitution by such court, this Agreement shall be automatically modified without further action by the parties hereto.

(c) For purposes of this Paragraph 13, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

14. Remedies.

The parties hereto agree that the Company would suffer irreparable harm from a breach by Executive of any of the covenants or agreements contained in Paragraphs 11, 12 or 13 of this Agreement. Therefore, in the event of the actual or threatened breach by Executive of any of the provisions of Paragraphs 11, 12 or 13 of this Agreement, the Company may, in addition and supplementary to other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violation of the provisions thereof.

15. Indemnification/Legal Fees.

19

(a) Indemnification. In the event the Executive is made party or threatened to be made a party to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "Proceeding"), by reason of Executive's employment with or serving as an officer or director of the Company, whether or not the basis of such Proceeding is alleged action in an official capacity, the Company shall indemnify, hold harmless and defend Executive to the fullest extent authorized by Maryland law, as the same exists and may hereafter be amended, against any and all claims, demands, suits, judgments, assessments and settlements including all expenses incurred or suffered by Executive in connection therewith (including, without limitation, all legal fees incurred using counsel reasonably acceptable to Executive) and such indemnification shall continue as to Executive even after Executive is no longer employed by the Company and shall inure to the benefit of his heirs, executors, and administrators. Expenses incurred by Executive in connection with any Proceeding shall be paid by the Company in advance upon request of Executive that the Company pay such expenses; but, only in the event that Executive shall have delivered in writing to the Company an undertaking to reimburse the Company for expenses with respect to which Executive is not entitled to indemnification. The provisions of this Paragraph shall remain in effect after this Agreement is terminated irrespective of the reasons for termination. The indemnification provisions of this Paragraph shall not supersede or reduce any indemnification provided to Executive under any separate agreement, or the by-laws of the Company since it is intended that this Agreement shall expand and extend the Executive's rights to receive indemnity.

20

(b) Legal Fees. If any contest or dispute shall arise between the Company and Executive regarding or as a result of any provision of this Agreement, the Company shall reimburse Executive for all legal fees and expenses reasonably incurred by Executive in connection with such contest or dispute, but only if Executive is successful in respect of substantially all of Executive's claims pursued or defended in connection with such contest or dispute. Such reimbursement shall be made as soon as practicable following the resolution of such contest or dispute (whether or not appealed).

16. Successors and Assigns.

(a) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance satisfactory to Executive, to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such agreement prior to the effectiveness of an such succession shall be a breach of this Agreement and shall entitle Executive to compensation from the Company in the same amount and on the same terms as he would be entitled to hereunder if Executive terminated his employment hereunder within six (6) months of a Change in Control as set forth in Paragraph 9, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the date of termination. In the event of such a breach of this Agreement, the Notice of Termination

21

shall specify such date as the date of termination. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to all or substantially all of its business and/or its assets as aforesaid which executes and delivers the agreement provided for in this Paragraph 16 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law. Any cash payments owed to Executive pursuant to this Paragraph 16 shall be paid to Executive in a single sum without discount for early payment immediately prior to the consummation of the transaction with such successor.

(b) This Agreement and all rights of Executive hereunder may be transferred only by will or the laws of descent and distribution. Upon Executive's death, this Agreement and all rights of Executive hereunder shall inure to the benefit of and be enforceable by Executive's beneficiary or beneficiaries, personal or legal representatives, or estate, to the extent any such person succeeds to Executive's interests under this Agreement. Executive shall be entitled to select and change a beneficiary or beneficiaries to receive any benefit or compensation payable hereunder following Executive's death by giving Company written notice thereof. If Executive should die following the date of termination while any amounts would still be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons so appointed in writing by Executive, including, without limitation, under any applicable plan, or otherwise to his legal representatives or estate.

17. Timing of and No Duplication of Payments.

22

All payments payable to Executive pursuant to this Agreement shall be paid as soon as practicable after such amounts have become fully vested and determinable. In addition, Executive shall not be entitled to receive duplicate payments under any of the provisions of this Agreement.

18. Modification or Waiver.

No amendment, modification, waiver, termination or cancellation of this Agreement shall be binding or effective for any purpose unless it is made in a writing signed by the party against whom enforcement of such amendment, modification, waiver, termination or cancellation is sought. No course of dealing between or among the parties to this Agreement shall be deemed to affect or to modify, amend or discharge any provision or term of this Agreement. No delay on the part of the Company or Executive in the exercise of any of their respective rights or remedies shall operate as a waiver thereof, and no single or partial exercise by the Company or Executive of any such right or remedy shall preclude other or further exercise thereof. A waiver of right or remedy on any one occasion shall not be construed as a bar to or waiver of any such right or remedy on any other occasion.

The respective rights and obligations of the parties hereunder shall survive the Executive's termination of employment and termination of this Agreement to the extent necessary for the intended preservation of such rights and obligations.

19. Notices.

23

All notices or other communications required or permitted hereunder shall be made in writing and shall be deemed to have been duly given if delivered by hand or delivered by a recognized delivery service or mailed, postage prepaid, by express, certified or registered mail, return receipt requested, and addressed to the Chief Executive Officer of the Company or Executive, as applicable, at the address set forth above (or to such other address as shall have been previously provided in accordance with this Paragraph 19).

20. Governing Law.

This agreement will be governed by and construed in accordance with the laws of the State of New Jersey except as to Paragraph 15(a), without regard to principles of conflicts of laws thereunder.

21. Severability.

Whenever possible, each provision and term of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or term of this Agreement shall be held to be prohibited by or invalid under such applicable law, then, subject to the provisions of sub-paragraph 13(b) above, such provision or term shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or affecting in any manner whatsoever the remainder of such provisions or term or the remaining provisions or terms of this Agreement.

22. Legal Representation.

24

Each of the Company and Executive have been represented by counsel with respect to this Agreement.

23. Counterparts.

This Agreement may be executed in separate counterparts, each of which is deemed to be an original and both of which taken together shall constitute one and the same agreement.

24. Headings.

The headings of the Paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute a part hereof and shall not affect the construction or interpretation of this Agreement.

25. Entire Agreement.

This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all other prior agreements and undertakings, both written and oral, among the parties with respect to the subject matter hereof. The parties recognize that the Prior Agreement has been amended and restated in its entirety by this Agreement and the terms of the Prior Agreement are of no further force and effect.

26. Survival of Agreements.

The covenants made in Paragraphs 5 through 15 and 21 each shall survive the termination of this Agreement.

25

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the date first above written.

AMENDED AND RESTATED EMPLOYMENT AGREEMENT

THIS AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of July 1, 1999, by and between Brant Cali, an individual residing at 175 Eagle Rock Way, Montclair, New Jersey 07042 ("Executive"), and Mack-Cali Realty Corporation, a Maryland corporation with offices at 11 Commerce Drive, Cranford, New Jersey 07016 (the "Company").

RECITALS

WHEREAS, Executive has served as Executive Vice President and Secretary of the Company pursuant to his prior employment agreement dated as of December 1997 (the "Prior Agreement") entered into as of the closing of the combination of Cali Realty Corporation with the Mack Companies (the "Mack Combination");

WHEREAS, Executive was appointed Chief Operating Officer of the Company on April 18, 1999;

WHEREAS, the Company and the Executive wish to amend and restate the Prior Agreement in its entirety among other things to acknowledge Executive's appointment as Chief Operating Officer, to provide for an award of Restricted Shares and a Tax Gross-Up Payment (as defined in sub-paragraph 4(c) below), to change the Employment Period (as defined in sub-paragraph 2(a) below) to (4) years and to amend the amount of the severance payment Executive may be eligible to receive upon termination of employment with the Company; and

WHEREAS, the Company desires to continue to employ Executive as Chief Operating Officer, Executive Vice President of Operations, Leasing and Marketing and Assistant Secretary, and Executive desires to continue to be employed by the Company


as Chief Operating Officer, Executive Vice President of Operations, Leasing and Marketing and Assistant Secretary, pursuant to the amended and restated terms set forth herein and to restate the Prior Agreement in its entirety

NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:

1. Employment.

The Company hereby agrees to employ Executive, and Executive hereby agrees to accept such employment during the period and upon the terms and conditions set forth in this Agreement.

2. Employment Period.

(a) Except as otherwise provided in this Agreement to the contrary, the terms and conditions of this Agreement shall be and remain in effect during the period of employment (the "Employment Period") established under this Paragraph 2. The initial Employment Period shall be for a term commencing on the date of this Agreement and ending on the fourth anniversary of the date of this Agreement provided, however, that commencing on the day after the date of this Agreement and on each day thereafter, the Employment Period shall be extended for one additional day so that a constant four (4) year Employment Period shall be in effect, unless (i) the Company or Executive elects not to extend the term of this Agreement by giving written notice to the other party in accordance with Paragraph 19, in which case, subject to the provisions of sub-paragraph 5(a)(iv) below, the term of this Agreement shall become

2

fixed and shall end on the fourth anniversary of the date of such written notice ("Notice of Non-Renewal"), or (ii) Executive's employment terminates hereunder.

(b) Notwithstanding anything contained herein to the contrary: (i) Executive's employment with the Company may be terminated by the Company or Executive during the Employment Period, subject to the terms and conditions of this Agreement; and (ii) nothing in this Agreement shall mandate or prohibit a continuation of Executive's employment following the expiration of the Employment Period upon such terms and conditions as the Board of Directors of the Company (the "Board") and Executive may mutually agree.

(c) If Executive's employment with the Company is terminated, for purposes of this Agreement the term "Unexpired Employment Period" shall mean the period commencing on the date of such termination and ending on the last day of the Employment Period.

3. Services / Place of Employment.

(a) Services. During the Employment Period, Executive shall hold the positions of Chief Operating Officer, Executive Vice President of Operations, Leasing and Marketing and Assistant Secretary of the Company. Executive shall devote his best efforts and substantially all of his business time, skill and attention to the business of the Company (other than absences due to vacation, illness, disability or approved leave of absence), and shall perform such duties as are customarily performed by similar executive officers and as may be more specifically enumerated from time to time by the Chief Executive Officer; provided, however, that the foregoing is not intended to

3

(a) preclude Executive from (i) owning and managing personal investments, including real estate investments, subject to the restrictions set forth in Paragraph 13 hereof or (ii) engaging in charitable activities and community affairs, or (b) restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to those properties described in Schedule A, attached hereto, (the "Excluded Properties"), provided that the performance of the activities referred to in clauses (a) and (b) does not prevent Executive from devoting substantially all of his business time to the Company.

(b) Place of Employment. The principal place of employment of Executive shall be at the Company's principal executive offices in Cranford, New Jersey.

4. Compensation and Benefits.

(a) Salary. During the Employment Period, the Company shall pay Executive a minimum annual base salary in the amount of $345,000 (the "Annual Base Salary") payable in accordance with the Company's regular payroll practices. Executive's Annual Base Salary shall be reviewed annually in accordance with the policy of the Company from time to time and may be subject to upward adjustment based upon, among other things, Executive's performance, as determined in the sole discretion of the Chief Executive Officer. In no event shall Executive's Annual Base Salary in effect at a particular time be reduced without his prior written consent.

(b) Incentive Compensation/Bonuses. In addition, Executive shall be eligible for incentive compensation payable each year in such amounts as may be

4

determined by the Option and Executive Compensation Committee of the Board (the "Compensation Committee"). Executive shall be entitled to receive such bonuses, restricted share awards and options to purchase shares of common stock, par value $0.01 per share, of the Company (the "Common Stock") as the Board or the Compensation Committee as the case may be shall approve, in its sole discretion, including, without limitation, options, restricted share awards and bonuses contingent upon Executive's performance and the achievement of specified financial and operating objectives.

(c) Restricted Share Award/Tax Gross-Up Payment. Pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 1, 1998 (the "SOP"), Executive has been awarded a restricted share award of 23,437 shares of Common Stock ("Restricted Shares") as of July 1, 1999 (the "Restricted Share Award"). Executive shall be entitled to receive a tax gross-up payment (the "Tax Gross-Up Payment") from the Company with respect to each tax year in which Restricted Shares granted pursuant to the Restricted Share Award vest and are distributed to him. Each Tax Gross-Up Payment shall be a dollar amount equal to forty-three (43%) percent of the fair market value of the Restricted Shares at time of vesting, exclusive of dividends. In the event vesting occurs with respect to any Restricted Shares as a result of the achievement of the required performance goals, such payment shall be made as soon as practicable after a determination that the performance goals have been achieved but in no event later than the 90th day of the fiscal year of the Company immediately following the fiscal year as to which the performance goals were achieved. In the event

5

vesting occurs for any other reason, including, without limitation, termination of Executive's employment by the Company without Cause or by Executive for Good Reason (but excluding a termination by the Company for Cause or a voluntary quit without Good Reason by Executive), such payment shall be made as soon as practicable after the date of vesting but in no event later than the tenth
(10th) business day following such vesting.

(d) Taxes and Withholding. The Company shall have the right to deduct and withhold from all compensation all social security and other federal, state and local taxes and charges which currently are or which hereafter may be required by law to be so deducted and withheld.

(e) Additional Benefits. In addition to the compensation specified above and other benefits provided pursuant to this Paragraph 4, Executive shall be entitled to the following benefits:

(i) participation in the SOP, the Mack-Cali Realty Corporation
401(k) Savings and Retirement Plan (subject to statutory rules and maximum contributions and non-discrimination requirements applicable to 401(k) plans) and such other benefit plans and programs, including but not limited to restricted stock, phantom stock and/or unit awards, loan programs and any other incentive compensation plans or programs (whether or not employee benefit plans or programs), as maintained by the Company from time to time and made generally available to executives of the Company with such participation to be consistent with reasonable Company guidelines;

(ii) participation in any health insurance, disability insurance, paid vacation, group life insurance or other welfare benefit program made generally available to executives of the Company; and

(iii) reimbursement for reasonable business expenses incurred by Executive in furtherance of the interests of the Company including a monthly allowance of twelve hundred ($1,200) which is intended

6

to cover the cost of local business-related travel expenses exclusive of amounts paid to third-parties (e.g. taxi service).

5. Termination of Employment and Change in Control.

(a) Executive's employment hereunder may be terminated during the Employment Period under the following circumstances:

(i) Cause. The Company shall have the right to terminate Executive's employment for Cause upon Executive's: (A) willful and continued failure to use best efforts to substantially perform his duties hereunder (other than any such failure resulting from Executive's incapacity due to physical or mental illness) for a period of thirty (30) days after written demand for substantial performance is delivered by the Company specifically identifying the manner in which the Company believes Executive has not substantially performed his duties; (B) willful misconduct and/or willful violation of Paragraph 11 hereof, which is materially economically injurious to the Company and the Partnership taken as a whole; (C) the willful violation of the provisions of Paragraph 13 hereof; or (D) conviction of, or plea of guilty to a felony. For purposes of this sub-paragraph 5(a), no act, or failure to act, on Executive's part shall be considered "willful" unless done, or omitted to be done, by him (I) not in good faith and (II) without reasonable belief that his action or omission was in furtherance of the interests of the Company.

(ii) Death. Executive's employment hereunder shall terminate upon his death.

(iii) Disability. The Company shall have the right to terminate Executive's employment due to "Disability" in the event that there is a determination by the Company, upon the advice of an independent qualified physician, reasonably acceptable to Executive, that Executive has become physically or mentally incapable of performing his duties under this Agreement and such disability has disabled Executive for a cumulative period of one hundred eighty (180) days within a twelve (12) month period.

(iv) Good Reason. Executive shall have the right to terminate his employment for "Good Reason": (A) upon the occurrence of any material breach of this Agreement by the Company which shall include but not be limited to; an assignment to Executive of duties materially and adversely inconsistent with Executive's status as

7

Chief Operating Officer, Executive Vice President of Operations, Leasing and Marketing and Assistant Secretary or a material or adverse alteration in the nature of or diminution in Executive's duties and/or responsibilities, reporting obligations, titles or authority; (B) upon a reduction in Executive's Annual Base Salary or a material reduction in other benefits (except for bonuses or similar discretionary payments) as in effect at the time in question, a failure to pay such amounts when due or any other failure by the Company to comply with Paragraph 4 hereof; (C) on or within six (6) months following the date a Notice of Non-Renewal is issued by the Company pursuant to Paragraph 2 hereof; (D) on or within six (6) months following a Change in Control (as hereinafter defined) in accordance with the provisions set forth in sub-paragraph 5(a)(vii) hereof; (E) upon any purported termination of Executive's employment for Cause which is not effected pursuant to the procedures of sub-paragraph 5(a)(i) (and for purposes of this Agreement, in the event of such failure to comply, no such purported termination shall be effective); or (F) upon the relocation of the Company's principal executive offices or Executive's own office location to a location more than thirty (30) miles away from Cranford, New Jersey.

(v) Without Cause. The Company shall have the right to terminate the Executive's employment hereunder without Cause subject to the terms and conditions of this Agreement.

(vi) Without Good Reason. The Executive shall have the right to terminate his employment hereunder without Good Reason subject to the terms and conditions of this Agreement.

(vii) Change in Control. Executive shall have the right to terminate his employment hereunder on or within six (6) months following a Change in Control. Such termination shall be deemed a termination for Good Reason hereunder. For purposes of this Agreement "Change in Control" shall mean that any of the following events has occurred: (A) any "person" or "group" of persons, as such terms are used in Sections 13 and 14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than any employee benefit plan sponsored by the Company, becomes the "beneficial owner", as such term is used in Section 13 of the Exchange Act, (irrespective of any vesting or waiting periods) of (I) Common Stock or any class of stock convertible into Common Stock and/or (II) Common OP Units or preferred units or any other class of units convertible into Common OP Units, in an amount equal to twenty (20%) percent or more of the sum total of the

8

Common Stock and the Common OP Units (treating all classes of outstanding stock, units or other securities convertible into stock units as if they were converted into Common Stock or Common OP Units as the case may be and then treating Common Stock and Common OP Units as if they were a single class) issued and outstanding immediately prior to such acquisition as if they were a single class and disregarding any equity raise in connection with the financing of such transaction; (B) any Common Stock is purchased pursuant to a tender or exchange offer other than an offer by the Company; (C) the dissolution or liquidation of the Company or the consummation of any merger or consolidation of the Company or any sale or other disposition of all or substantially all of its assets, if the shareholders of the Company and unitholders of the Partnership taken as a whole and considered as one class immediately before such transaction own, immediately after consummation of such transaction, equity securities and partnership units possessing less than fifty (50%) percent of the surviving or acquiring company and partnership taken as a whole; or (D) a turnover, during any two (2) year period, of the majority of the members of the Board, without the consent of the remaining members of the Board as to the appointment of the new Board members.

(b) Notice of Termination. Any termination of Executive's employment by the Company or any such termination by Executive (other than on account of death) shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive's employment under the provision so indicated. In the event of the termination of Executive's employment on account of death, written Notice of Termination shall be deemed to have been provided on the date of death.

9

6. Compensation Upon Termination of Employment By the Company for Cause or By Executive without Good Reason.

In the event the Company terminates Executive's employment for Cause or Executive terminates his employment without Good Reason, the Company shall pay Executive any unpaid Annual Base Salary at the rate then in effect accrued through and including the date of termination. In addition, in such event, Executive shall be entitled (i) to receive any earned but unpaid incentive compensation or bonuses and (ii) to exercise any options which have vested and are exercisable in accordance with the terms of the applicable option grant agreement or plan, and (iii) to retain and/or receive any Restricted Shares which have vested as of the last day of the Company's fiscal year coincident or immediately preceding Executive's termination of employment and the corresponding Tax Gross-Up Payment (irrespective of whether the determination is made after Executive's termination of employment).

Except for any rights which Executive may have to unpaid salary amounts through and including the date of termination, earned but unpaid incentive compensation or bonuses, vested options, vested Restricted Shares and the corresponding Tax Gross-Up Payment, the Company shall have no further obligations hereunder following such termination. The aforesaid amounts shall be payable in full immediately upon such termination.

7. Compensation Upon Termination of Employment Upon Death or Disability.

In the event of termination of Executive's employment as a result of either Executive's death or Disability, the Company shall pay to Executive, his estate or his

10

personal representative the aggregate of (i) a cash payment of two million five hundred thousand dollars ($2,500,000) in full immediately upon such termination (the "Fixed Amount") and (ii) reimbursement of expenses incurred prior to date of termination ("Expense Reimbursement"). Executive (and Executive's dependents) shall also receive continuation of health coverage through the end of the Unexpired Employment Period on the same basis as health coverage is provided by the Company for active employees and as may be amended from time to time ("Medical Continuation").

In addition, all (A) incentive compensation payments or programs of any nature whether stock based or otherwise that are subject to a vesting schedule including, without limitation, the Restricted Share Award or any other restricted stock, phantom stock, units and any loan forgiveness arrangements granted to Executive ("Incentive Compensation") shall immediately vest as of the date of such termination ("Vested Incentive Compensation"), (B) options granted to Executive shall immediately vest as of the date of such termination (the "Vested Options") and Executive shall be entitled at the option of Executive, his estate or his personal representative, within one (1) year of the date of such termination, to exercise the Vested Options and/or other options which have vested (including, without limitation, all other options which have previously vested in accordance with the Prior Agreement, any applicable option grant agreement or plan) (the "Total Vested Options") and are exercisable in accordance with the terms of the applicable option grant agreement or plan and/or any other methods or procedures for exercise applicable to optionees or to require the Company (upon written notice delivered within one hundred eighty
(180) days following the date of Executive's termination) to repurchase all or any portion of Executive's vested options to purchase

11

shares of Common Stock at a price equal to the difference between the Repurchase Fair Market Value (as hereinafter defined) of the shares of Common Stock for which the options to be repurchased are exercisable and the exercise price of such options as of the date of Executive's termination of employment (the "Vested Option Exercise Election"), and (C) the Tax Gross-Up Payment(s) applicable to the Restricted Share Award shall vest and be paid to Executive at such time as provided in sub-paragraph 4(c) above (the "Vested Tax Gross-Up Payments"). In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

Except for any rights which Executive or Executive's estate in the event of Executive's death may have to all of the above including the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation (which, in the event of Executive's death, shall be provided to Executive's dependents), the Company shall have no further obligations hereunder following such termination.

For purposes of this Agreement, "Repurchase Fair Market Value" shall mean the average of the closing price on the New York Stock Exchange (or such other exchange on which the Common Stock is primarily traded) of the Common Stock on each of the trading days within the thirty (30) days immediately preceding the date of termination of Executive's employment.

12

8. Compensation Upon Termination of Employment By the Company Without Cause or By Executive for Good Reason.

In the event the Company terminates Executive's employment for any reason other than Cause or Executive terminates his employment for Good Reason, the Company shall pay to Executive and Executive shall be entitled to receive the aggregate of (i) the Fixed Amount and (ii) Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control. Executive understands that any options exercised more than ninety
(90) days following the date of his termination of employment which were granted as incentive stock options shall automatically be converted into non-qualified options.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation, the Company shall have no further obligations hereunder following such termination. The parties both agree that the agreement to make these payments was consideration and an inducement to obtain Executive's consent to enter into this Agreement. The payments are not a penalty and neither party will claim them to be a penalty. Rather, the payments represent a fair approximation of reasonable amounts due to Executive for the Employment Period.

13

9. Change in Control.

(a) Options. Any Incentive Compensation and options granted to Executive that have not vested as of the date of a Change in Control shall immediately vest upon the date of the Change in Control. Neither the occurrence of a Change in Control, nor the vesting in any options as a result thereof shall require Executive to exercise any options. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

(b) Upon Termination. In the event Executive terminates his employment on or following a Change in Control as set forth in sub-paragraph
5(a)(vii), the Company shall pay to Executive and Executive shall be entitled to all the payments and rights Executive would have had if Executive had terminated his employment with Good Reason as set forth in Paragraph 8.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options (including, without limitation, by acceleration in accordance with sub-paragraph 9(a)) and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement, Medical Continuation, and the Excise Tax Gross Up set forth in subparagraph 9(c), the Company shall have no further obligations hereunder following such termination.

(c) Excise Tax Gross Up. In addition, if it is determined by an independent accountant mutually acceptable to the Company and Executive that as a result of any payment in the nature of compensation made by the Company to (or for

14

the benefit of) Executive pursuant to this Agreement or otherwise, an excise tax may be imposed on Executive pursuant to Section 4999 of the Code (or any successor provisions), the Company shall pay Executive in cash an amount equal to X determined under the following formula: (the "Excise Tax Gross Up"):

E x P

X = --------------------------------

            1-[(FI x (1-SLI)) + SLI + E + M]

where

E     =     the rate at which the excise tax is assessed under
            Section 4999 of the Code (or any successor provisions);

P     =     the amount with respect to which such excise tax is
            assessed, determined without regard to the Excise Tax
            Gross Up;

FI    =     the highest effective marginal rate of income tax
            applicable to Executive under the Code for the taxable
            year in question (taking into account any phase-out or
            loss of deductions, personal exemptions or other similar
            adjustments);

SLI   =     the sum of the highest effective marginal rates of
            income tax applicable to Executive under all applicable
            state and local laws for the taxable year in question
            (taking into account any phase-out or loss of
            deductions, personal exemptions and other similar
            adjustments); and

M     =     the highest marginal rate of Medicare tax applicable to
            Executive under the Code for the taxable year in
            question.

With respect to any payment in the nature of compensation that is made to (or for the benefit of) Executive under the terms of this Agreement or otherwise and on which an excise tax under Section 4999 of the Code (or any successor provisions) may be assessed, the payment determined under this sub-paragraph 9(c) shall be paid to Executive at the time of the Change in Control but prior to the consummation of the

15

transaction with any successor. It is the intention of the parties that the Company provide Executive with a full tax gross-up under the provisions of this sub-paragraph, so that on a net after-tax basis, the result to Executive shall be the same as if the excise tax under Section 4999 of the Code (or any successor provisions) had not been imposed. The Excise Tax Gross Up may be adjusted if alternative minimum tax rules are applicable to Executive.

10. Mitigation / Effect on Employee Benefit Plans and Programs.

(a) Mitigation. Executive shall not be required to mitigate amounts payable under this Agreement by seeking other employment or otherwise, and there shall be no offset against amounts due Executive under this Agreement on account of subsequent employment. Amounts owed to Executive under this Agreement shall not be offset by any claims the Company may have against Executive and such payment shall not be affected by any other circumstances, including, without limitation, any counterclaim, recoupment, defense, or other right which the Company may have against Executive or others.

(b) Effect on Employee Benefit Programs. The termination of Executive's employment hereunder, whether by the Company or Executive, shall have no effect on the rights and obligations of the parties hereto under the Company's (i) welfare benefit plans including, without limitation, Medical Continuation as provided for herein and, health coverage thereafter but only to the extent required by law, and on the same basis applicable to other employees and (ii) 401(k) Plan but only to the extent required by law and pursuant to the terms of the 401(k) Plan.

16

11. Confidential Information.

(a) Executive understands and acknowledges that during his employment with the Company, he will be exposed to Confidential Information (as defined below), all of which is proprietary and which will rightfully belong to the Company. Executive shall hold in a fiduciary capacity for the benefit of the Company such Confidential Information obtained by Executive during his employment with the Company and shall not, directly or indirectly, at any time, either during or after his employment with the Company, without the Company's prior written consent, use any of such Confidential Information or disclose any of such Confidential Information to any individual or entity other than the Company or its employees, attorneys, accountants, financial advisors, consultants, or investment bankers except as required in the performance of his duties for the Company or as otherwise required by law. Executive shall take all reasonable steps to safeguard such Confidential Information and to protect such Confidential Information against disclosure, misuse, loss or theft.

(b) The term "Confidential Information" shall mean any information not generally known in the relevant trade or industry or otherwise not generally available to the public, which was obtained from the Company or its predecessors or which was learned, discovered, developed, conceived, originated or prepared during or as a result of the performance of any services by Executive on behalf of the Company or its predecessors. For purposes of this Paragraph 11, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any

17

entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

12. Return of Documents.

Except for such items which are of a personal nature to Executive (e.g., daily business planner), all writings, records, and other documents and things containing any Confidential Information shall be the exclusive property of the Company, shall not be copied, summarized, extracted from, or removed from the premises of the Company, except in pursuit of the business of the Company and at the direction of the Company, and shall be delivered to the Company, without retaining any copies, upon the termination of Executive's employment or at any time as requested by the Company.

13. Noncompete.

Executive agrees that:

(a) During the Employment Period and, in the event (i) the Company terminates Executive's employment for Cause, or (ii) Executive terminates his employment without Good Reason, for a one (1) year period thereafter, Executive shall not, directly or indirectly, within the continental United States, engage in, or own, invest in, manage or control any venture or enterprise primarily engaged in any office-service, flex, or office property development, acquisition or management activities without regard to whether or not such activities compete with the Company. Nothing herein shall prohibit Executive from being a passive owner of not more than five percent (5%) of the outstanding stock of any class of securities of a corporation or other entity

18

engaged in such business which is publicly traded, so long as he has no active participation in the business of such corporation or other entity. Moreover, the foregoing limitations shall not be deemed to restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to the Excluded Properties, if any, provided that during the Employment Period the performance of such activities does not prevent Executive from devoting substantially all of his business time to the Company.

(b) If, at the time of enforcement of this Paragraph 13, a court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable, the parties agree that reasonable maximum duration, scope, area or other restrictions may be substituted by such court for the stated duration, scope, area or other restrictions and upon substitution by such court, this Agreement shall be automatically modified without further action by the parties hereto.

(c) For purposes of this Paragraph 13, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

14. Remedies.

The parties hereto agree that the Company would suffer irreparable harm from a breach by Executive of any of the covenants or agreements contained in Paragraphs 11, 12 or 13 of this

19

Agreement. Therefore, in the event of the actual or threatened breach by Executive of any of the provisions of Paragraphs 11, 12 or 13 of this Agreement, the Company may, in addition and supplementary to other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violation of the provisions thereof.

15. Indemnification/Legal Fees.

(a) Indemnification. In the event the Executive is made party or threatened to be made a party to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "Proceeding"), by reason of Executive's employment with or serving as an officer or director of the Company, whether or not the basis of such Proceeding is alleged action in an official capacity, the Company shall indemnify, hold harmless and defend Executive to the fullest extent authorized by Maryland law, as the same exists and may hereafter be amended, against any and all claims, demands, suits, judgments, assessments and settlements including all expenses incurred or suffered by Executive in connection therewith (including, without limitation, all legal fees incurred using counsel reasonably acceptable to Executive) and such indemnification shall continue as to Executive even after Executive is no longer employed by the Company and shall inure to the benefit of his heirs, executors, and administrators. Expenses incurred by Executive in connection with any Proceeding shall be paid by the Company in advance upon request of Executive that the Company pay such expenses; but, only in the event that Executive shall have delivered in writing to the Company an undertaking to reimburse the Company for expenses with respect to which Executive is not entitled to indemnification. The provisions of this Paragraph

20

shall remain in effect after this Agreement is terminated irrespective of the reasons for termination. The indemnification provisions of this Paragraph shall not supersede or reduce any indemnification provided to Executive under any separate agreement, or the by-laws of the Company since it is intended that this Agreement shall expand and extend the Executive's rights to receive indemnity.

(b) Legal Fees. If any contest or dispute shall arise between the Company and Executive regarding or as a result of any provision of this Agreement, the Company shall reimburse Executive for all legal fees and expenses reasonably incurred by Executive in connection with such contest or dispute, but only if Executive is successful in respect of substantially all of Executive's claims pursued or defended in connection with such contest or dispute. Such reimbursement shall be made as soon as practicable following the resolution of such contest or dispute (whether or not appealed).

16. Successors and Assigns.

(a) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance satisfactory to Executive, to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such agreement prior to the effectiveness of an such succession shall be a breach of this Agreement and shall entitle Executive to compensation from the Company in the

21

same amount and on the same terms as he would be entitled to hereunder if Executive terminated his employment hereunder within six (6) months of a Change in Control as set forth in Paragraph 9, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the date of termination. In the event of such a breach of this Agreement, the Notice of Termination shall specify such date as the date of termination. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to all or substantially all of its business and/or its assets as aforesaid which executes and delivers the agreement provided for in this Paragraph 16 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law. Any cash payments owed to Executive pursuant to this Paragraph 16 shall be paid to Executive in a single sum without discount for early payment immediately prior to the consummation of the transaction with such successor.

(b) This Agreement and all rights of Executive hereunder may be transferred only by will or the laws of descent and distribution. Upon Executive's death, this Agreement and all rights of Executive hereunder shall inure to the benefit of and be enforceable by Executive's beneficiary or beneficiaries, personal or legal representatives, or estate, to the extent any such person succeeds to Executive's interests under this Agreement. Executive shall be entitled to select and change a beneficiary or beneficiaries to receive any benefit or compensation payable hereunder following Executive's death by giving Company written notice thereof. If Executive should die following the date of termination while any amounts would still be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided

22

herein, shall be paid in accordance with the terms of this Agreement to such person or persons so appointed in writing by Executive, including, without limitation, under any applicable plan, or otherwise to his legal representatives or estate.

17. Timing of and No Duplication of Payments.

All payments payable to Executive pursuant to this Agreement shall be paid as soon as practicable after such amounts have become fully vested and determinable. In addition, Executive shall not be entitled to receive duplicate payments under any of the provisions of this Agreement.

18. Modification or Waiver.

No amendment, modification, waiver, termination or cancellation of this Agreement shall be binding or effective for any purpose unless it is made in a writing signed by the party against whom enforcement of such amendment, modification, waiver, termination or cancellation is sought. No course of dealing between or among the parties to this Agreement shall be deemed to affect or to modify, amend or discharge any provision or term of this Agreement. No delay on the part of the Company or Executive in the exercise of any of their respective rights or remedies shall operate as a waiver thereof, and no single or partial exercise by the Company or Executive of any such right or remedy shall preclude other or further exercise thereof. A waiver of right or remedy on any one occasion shall not be construed as a bar to or waiver of any such right or remedy on any other occasion.

23

The respective rights and obligations of the parties hereunder shall survive the Executive's termination of employment and termination of this Agreement to the extent necessary for the intended preservation of such rights and obligations.

19. Notices.

All notices or other communications required or permitted hereunder shall be made in writing and shall be deemed to have been duly given if delivered by hand or delivered by a recognized delivery service or mailed, postage prepaid, by express, certified or registered mail, return receipt requested, and addressed to the Chief Executive Officer of the Company or Executive, as applicable, at the address set forth above (or to such other address as shall have been previously provided in accordance with this Paragraph 19).

20. Governing Law.

This agreement will be governed by and construed in accordance with the laws of the State of New Jersey except as to Paragraph 15(a), without regard to principles of conflicts of laws thereunder.

21. Severability.

Whenever possible, each provision and term of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or term of this Agreement shall be held to be prohibited by or invalid under such applicable law, then, subject to the provisions of sub-paragraph 13(b) above, such provision or term shall be ineffective only to the extent of such prohibition or invalidity,

24

without invalidating or affecting in any manner whatsoever the remainder of such provisions or term or the remaining provisions or terms of this Agreement.

25

22. Legal Representation.

Each of the Company and Executive have been represented by counsel with respect to this Agreement.

23. Counterparts.

This Agreement may be executed in separate counterparts, each of which is deemed to be an original and both of which taken together shall constitute one and the same agreement.

24. Headings.

The headings of the Paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute a part hereof and shall not affect the construction or interpretation of this Agreement.

25. Entire Agreement.

This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all other prior agreements and undertakings, both written and oral, among the parties with respect to the subject matter hereof. The parties recognize that the Prior Agreement has been amended and restated in its entirety by this Agreement and the terms of the Prior Agreement are of no further force and effect.

26

26. Survival of Agreements.

The covenants made in Paragraphs 5 through 15 and 21 each shall survive the termination of this Agreement.

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the date first above written.

THIS SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of July 1, 1999, by and between Barry Lefkowitz, an individual residing at 4 Borden Place, Livingston, New Jersey 07039 ("Executive"), and Mack-Cali Realty Corporation, a Maryland corporation with offices at 11 Commerce Drive, Cranford, New Jersey 07016 (the "Company").

RECITALS

WHEREAS, Executive has served as Executive Vice President Finance and Chief Financial Officer of the Company pursuant to his prior employment agreement dated as of December 1997 (the "Prior Agreement") entered into as of the closing of the combination of Cali Realty Corporation with the Mack Companies (the "Mack Combination");

WHEREAS, the Company and the Executive wish to amend and restate the Prior Agreement in its entirety to provide for an award of Restricted Shares and a Tax Gross-Up Payment (as defined in sub-paragraph 4(c) below), to change the Employment Period (as defined in sub-paragraph 2(a) below) to (4) years and to amend the amount of the severance payment Executive may be eligible to receive upon termination of employment with the Company; and

WHEREAS, the Company desires to continue to employ Executive as Executive Vice President and Chief Financial Officer, and Executive desires to continue to be employed by the Company as Executive Vice President and Chief Financial Officer, pursuant to the amended and restated terms set forth herein and to restate the Prior Agreement in its entirety


NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:

1. Employment.

The Company hereby agrees to employ Executive, and Executive hereby agrees to accept such employment during the period and upon the terms and conditions set forth in this Agreement.

Executive shall be entitled to receive a tax gross-up payment (the "Tax Gross-Up Payment") from the Company with respect to each tax year in which Restricted Shares granted pursuant to the Restricted Share Award vest and are distributed to him. Each Tax Gross-Up Payment shall be a dollar amount equal to forty-three (43%) percent of the fair market value of the Restricted Shares at time of vesting, exclusive of dividends. In the event vesting occurs with respect to any Restricted Shares as a result of the achievement of the required performance goals, such payment shall be made as soon as practicable after a determination that the performance goals have been achieved but in no event later than the 90th day of the fiscal year of the Company immediately following the fiscal year as to which the performance goals were achieved. In the event vesting occurs for any other reason, including, without limitation, termination of Executive's employment by the Company without Cause or by Executive for Good Reason (but excluding a termination by the Company for Cause or a voluntary quit without Good Reason by Executive), such payment shall be made as soon as

5

practicable after the date of vesting but in no event later than the tenth
(10th) business day following such vesting.

(i) Cause. The Company shall have the right to terminate Executive's employment for Cause upon Executive's: (A) willful and continued failure to use best efforts to substantially perform his duties hereunder (other than any such failure resulting from Executive's incapacity due to physical or mental illness) for a period of thirty (30) days after written demand for substantial performance is delivered by the Company specifically identifying the manner in which the Company believes Executive has not substantially performed his duties; (B) willful misconduct and/or willful violation of Paragraph 11 hereof, which is materially economically injurious to the Company and the Partnership taken as a whole; (C) the willful violation of the provisions of Paragraph 13 hereof; or (D) conviction of, or plea of guilty to a felony.

(v) Without Cause. The Company shall have the right to terminate the Executive's employment hereunder without Cause subject to the terms and conditions of this Agreement.

(vi) Without Good Reason. The Executive shall have the right to terminate his employment hereunder without Good Reason subject to the terms and conditions of this Agreement.

(vii) Change in Control. Executive shall have the right to terminate his employment hereunder on or within six (6) months following a Change in Control. Such termination shall be deemed a termination for Good Reason hereunder. For purposes of this Agreement "Change in Control" shall mean that any of the following events has occurred: (A) any "person" or "group" of persons, as such terms are used in Sections 13 and 14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than any employee benefit plan sponsored by the Company, becomes the "beneficial owner", as such term is used in Section 13 of the Exchange Act, (irrespective of any vesting or waiting periods) of (I) Common Stock or any class of stock convertible into Common Stock and/or (II) Common OP Units or preferred units or any other class of units convertible into Common OP Units, in an amount equal to twenty (20%) percent or more of the sum total of the Common Stock and the Common OP Units (treating all classes of outstanding stock, units or other securities convertible into stock units as if they were converted into Common Stock or Common OP Units as the case may be and then treating Common Stock and Common OP Units as if they were a single class) issued and outstanding immediately prior to such acquisition as if they were a single class and disregarding any equity raise in connection with

8

the financing of such transaction; (B) any Common Stock is purchased pursuant to a tender or exchange offer other than an offer by the Company; (C) the dissolution or liquidation of the Company or the consummation of any merger or consolidation of the Company or any sale or other disposition of all or substantially all of its assets, if the shareholders of the Company and unitholders of the Partnership taken as a whole and considered as one class immediately before such transaction own, immediately after consummation of such transaction, equity securities and partnership units possessing less than fifty (50%) percent of the surviving or acquiring company and partnership taken as a whole; or (D) a turnover, during any two (2) year period, of the majority of the members of the Board, without the consent of the remaining members of the Board as to the appointment of the new Board members.

(b) Notice of Termination. Any termination of Executive's employment by the Company or any such termination by Executive (other than on account of death) shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive's employment under the provision so indicated. In the event of the termination of Executive's employment on account of death, written Notice of Termination shall be deemed to have been provided on the date of death.

6. Compensation Upon Termination of Employment By the Company for Cause or By Executive without Good Reason.

In the event the Company terminates Executive's employment for Cause or Executive terminates his employment without Good Reason, the Company shall pay Executive any unpaid Annual Base Salary at the rate then in effect accrued through and

9

including the date of termination. In addition, in such event, Executive shall be entitled (i) to receive any earned but unpaid incentive compensation or bonuses and (ii) to exercise any options which have vested and are exercisable in accordance with the terms of the applicable option grant agreement or plan, and (iii) to retain and/or receive any Restricted Shares which have vested as of the last day of the Company's fiscal year coincident or immediately preceding Executive's termination of employment and the corresponding Tax Gross-Up Payment (irrespective of whether the determination is made after Executive's termination of employment).

Except for any rights which Executive may have to unpaid salary amounts through and including the date of termination, earned but unpaid incentive compensation or bonuses, vested options, vested Restricted Shares and the corresponding Tax Gross-Up Payment, the Company shall have no further obligations hereunder following such termination. The aforesaid amounts shall be payable in full immediately upon such termination.

7. Compensation Upon Termination of Employment Upon Death or Disability.

In the event of termination of Executive's employment as a result of either Executive's death or Disability, the Company shall pay to Executive, his estate or his personal representative the aggregate of (i) a cash payment of two million five hundred thousand dollars ($2,500,000) in full immediately upon such termination (the "Fixed Amount") and (ii) reimbursement of expenses incurred prior to date of termination ("Expense Reimbursement"). Executive (and Executive's dependents) shall also receive continuation of health coverage through the end of the Unexpired Employment

10

Period on the same basis as health coverage is provided by the Company for active employees and as may be amended from time to time ("Medical Continuation").

In addition, all (A) incentive compensation payments or programs of any nature whether stock based or otherwise that are subject to a vesting schedule including, without limitation, the Restricted Share Award or any other restricted stock, phantom stock, units and any loan forgiveness arrangements granted to Executive ("Incentive Compensation") shall immediately vest as of the date of such termination ("Vested Incentive Compensation"), (B) options granted to Executive shall immediately vest as of the date of such termination (the "Vested Options") and Executive shall be entitled at the option of Executive, his estate or his personal representative, within one (1) year of the date of such termination, to exercise the Vested Options and/or other options which have vested (including, without limitation, all other options which have previously vested in accordance with the Prior Agreement, any applicable option grant agreement or plan) (the "Total Vested Options") and are exercisable in accordance with the terms of the applicable option grant agreement or plan and/or any other methods or procedures for exercise applicable to optionees or to require the Company (upon written notice delivered within one hundred eighty
(180) days following the date of Executive's termination) to repurchase all or any portion of Executive's vested options to purchase shares of Common Stock at a price equal to the difference between the Repurchase Fair Market Value (as hereinafter defined) of the shares of Common Stock for which the options to be repurchased are exercisable and the exercise price of such options as of the date of Executive's termination of employment (the "Vested Option Exercise Election"), and (C) the Tax Gross-Up Payment(s) applicable to the Restricted Share

11

Award shall vest and be paid to Executive at such time as provided in sub-paragraph 4(c) above (the "Vested Tax Gross-Up Payments"). In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

Except for any rights which Executive or Executive's estate in the event of Executive's death may have to all of the above including the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation (which, in the event of Executive's death, shall be provided to Executive's dependents), the Company shall have no further obligations hereunder following such termination.

For purposes of this Agreement, "Repurchase Fair Market Value" shall mean the average of the closing price on the New York Stock Exchange (or such other exchange on which the Common Stock is primarily traded) of the Common Stock on each of the trading days within the thirty (30) days immediately preceding the date of termination of Executive's employment.

8. Compensation Upon Termination of Employment By the Company Without Cause or By Executive for Good Reason.

In the event the Company terminates Executive's employment for any reason other than Cause or Executive terminates his employment for Good Reason, the Company shall pay to Executive and Executive shall be entitled to receive the aggregate of (i) the Fixed Amount and (ii) Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment,

12

Expense Reimbursement and Medical Continuation. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control. Executive understands that any options exercised more than ninety (90) days following the date of his termination of employment which were granted as incentive stock options shall automatically be converted into non-qualified options.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation, the Company shall have no further obligations hereunder following such termination. The parties both agree that the agreement to make these payments was consideration and an inducement to obtain Executive's consent to enter into this Agreement. The payments are not a penalty and neither party will claim them to be a penalty. Rather, the payments represent a fair approximation of reasonable amounts due to Executive for the Employment Period.

9. Change in Control.

(a) Options. Any Incentive Compensation and options granted to Executive that have not vested as of the date of a Change in Control shall immediately vest upon the date of the Change in Control. Neither the occurrence of a Change in Control, nor the vesting in any options as a result thereof shall require Executive to exercise any options. In the event of a conflict between any Incentive Compensation

13

grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

(b) Upon Termination. In the event Executive terminates his employment on or following a Change in Control as set forth in sub-paragraph
5(a)(vii), the Company shall pay to Executive and Executive shall be entitled to all the payments and rights Executive would have had if Executive had terminated his employment with Good Reason as set forth in Paragraph 8.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options (including, without limitation, by acceleration in accordance with sub-paragraph 9(a)) and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement, Medical Continuation and the Excise Tax Gross Up set forth in subparagraph 9(c), the Company shall have no further obligations hereunder following such termination.

(c) Excise Tax Gross Up. In addition, if it is determined by an independent accountant mutually acceptable to the Company and Executive that as a result of any payment in the nature of compensation made by the Company to (or for the benefit of) Executive pursuant to this Agreement or otherwise, an excise tax may be imposed on Executive pursuant to Section 4999 of the Code (or any successor provisions), the Company shall pay Executive in cash an amount equal to X determined under the following formula: (the "Excise Tax Gross Up"):

E x P

X = --------------------------------

1-[(FI x (1-SLI)) + SLI + E + M]

where

14

E     =     the rate at which the excise tax is assessed under
            Section 4999 of the Code (or any successor provisions);

P     =     the amount with respect to which such excise tax is
            assessed, determined without regard to the Excise Tax
            Gross Up;

FI    =     the highest effective marginal rate of income tax
            applicable to Executive under the Code for the taxable
            year in question (taking into account any phase-out or
            loss of deductions, personal exemptions or other similar
            adjustments);

SLI   =     the sum of the highest effective marginal rates of
            income tax applicable to Executive under all applicable
            state and local laws for the taxable year in question
            (taking into account any phase-out or loss of
            deductions, personal exemptions and other similar
            adjustments); and

M     =     the highest marginal rate of Medicare tax applicable to
            Executive under the Code for the taxable year in
            question.

With respect to any payment in the nature of compensation that is made to (or for the benefit of) Executive under the terms of this Agreement or otherwise and on which an excise tax under Section 4999 of the Code (or any successor provisions) may be assessed, the payment determined under this sub-paragraph 9(c) shall be paid to Executive at the time of the Change in Control but prior to the consummation of the transaction with any successor. It is the intention of the parties that the Company provide Executive with a full tax gross-up under the provisions of this sub-paragraph, so that on a net after-tax basis, the result to Executive shall be the same as if the excise tax under Section 4999 of the Code (or any successor provisions) had not been imposed. The Excise Tax Gross Up may be adjusted if alternative minimum tax rules are applicable to Executive.

15

10. Mitigation / Effect on Employee Benefit Plans and Programs.

(a) Mitigation. Executive shall not be required to mitigate amounts payable under this Agreement by seeking other employment or otherwise, and there shall be no offset against amounts due Executive under this Agreement on account of subsequent employment. Amounts owed to Executive under this Agreement shall not be offset by any claims the Company may have against Executive and such payment shall not be affected by any other circumstances, including, without limitation, any counterclaim, recoupment, defense, or other right which the Company may have against Executive or others.

(b) Effect on Employee Benefit Programs. The termination of Executive's employment hereunder, whether by the Company or Executive, shall have no effect on the rights and obligations of the parties hereto under the Company's (i) welfare benefit plans including, without limitation, Medical Continuation as provided for herein and, health coverage thereafter but only to the extent required by law, and on the same basis applicable to other employees and (ii) 401(k) Plan but only to the extent required by law and pursuant to the terms of the 401(k) Plan.

11. Confidential Information.

(a) Executive understands and acknowledges that during his employment with the Company, he will be exposed to Confidential Information (as defined below), all of which is proprietary and which will rightfully belong to the

16

Company. Executive shall hold in a fiduciary capacity for the benefit of the Company such Confidential Information obtained by Executive during his employment with the Company and shall not, directly or indirectly, at any time, either during or after his employment with the Company, without the Company's prior written consent, use any of such Confidential Information or disclose any of such Confidential Information to any individual or entity other than the Company or its employees, attorneys, accountants, financial advisors, consultants, or investment bankers except as required in the performance of his duties for the Company or as otherwise required by law. Executive shall take all reasonable steps to safeguard such Confidential Information and to protect such Confidential Information against disclosure, misuse, loss or theft.

(b) The term "Confidential Information" shall mean any information not generally known in the relevant trade or industry or otherwise not generally available to the public, which was obtained from the Company or its predecessors or which was learned, discovered, developed, conceived, originated or prepared during or as a result of the performance of any services by Executive on behalf of the Company or its predecessors. For purposes of this Paragraph 11, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

12. Return of Documents.

Except for such items which are of a personal nature to Executive (e.g., daily business planner), all writings, records, and other documents and things containing any

17

Confidential Information shall be the exclusive property of the Company, shall not be copied, summarized, extracted from, or removed from the premises of the Company, except in pursuit of the business of the Company and at the direction of the Company, and shall be delivered to the Company, without retaining any copies, upon the termination of Executive's employment or at any time as requested by the Company.

13. Noncompete. Executive agrees that:

(a) During the Employment Period and, in the event (i) the Company terminates Executive's employment for Cause, or (ii) Executive terminates his employment without Good Reason, for a one (1) year period thereafter, Executive shall not, directly or indirectly, within the continental United States, engage in, or own, invest in, manage or control any venture or enterprise primarily engaged in any office-service, flex, or office property development, acquisition or management activities without regard to whether or not such activities compete with the Company. Nothing herein shall prohibit Executive from being a passive owner of not more than five percent (5%) of the outstanding stock of any class of securities of a corporation or other entity engaged in such business which is publicly traded, so long as he has no active participation in the business of such corporation or other entity. Moreover, the foregoing limitations shall not be deemed to restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to the Excluded Properties, if any, provided that during the Employment Period the

18

performance of such activities does not prevent Executive from devoting substantially all of his business time to the Company.

(b) If, at the time of enforcement of this Paragraph 13, a court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable, the parties agree that reasonable maximum duration, scope, area or other restrictions may be substituted by such court for the stated duration, scope, area or other restrictions and upon substitution by such court, this Agreement shall be automatically modified without further action by the parties hereto.

(c) For purposes of this Paragraph 13, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

19

14. Remedies.

The parties hereto agree that the Company would suffer irreparable harm from a breach by Executive of any of the covenants or agreements contained in Paragraphs 11, 12 or 13 of this Agreement. Therefore, in the event of the actual or threatened breach by Executive of any of the provisions of Paragraphs 11, 12 or 13 of this Agreement, the Company may, in addition and supplementary to other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violation of the provisions thereof.

15. Indemnification/Legal Fees.

(a) Indemnification. In the event the Executive is made party or threatened to be made a party to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "Proceeding"), by reason of Executive's employment with or serving as an officer or director of the Company, whether or not the basis of such Proceeding is alleged action in an official capacity, the Company shall indemnify, hold harmless and defend Executive to the fullest extent authorized by Maryland law, as the same exists and may hereafter be amended, against any and all claims, demands, suits, judgments, assessments and settlements including all expenses incurred or suffered by Executive in connection therewith (including, without limitation, all legal fees incurred using counsel reasonably acceptable to Executive) and such indemnification shall continue as to Executive even after Executive is no longer employed by the Company and shall inure to the benefit of his heirs, executors, and

20

administrators. Expenses incurred by Executive in connection with any Proceeding shall be paid by the Company in advance upon request of Executive that the Company pay such expenses; but, only in the event that Executive shall have delivered in writing to the Company an undertaking to reimburse the Company for expenses with respect to which Executive is not entitled to indemnification. The provisions of this Paragraph shall remain in effect after this Agreement is terminated irrespective of the reasons for termination. The indemnification provisions of this Paragraph shall not supersede or reduce any indemnification provided to Executive under any separate agreement, or the by-laws of the Company since it is intended that this Agreement shall expand and extend the Executive's rights to receive indemnity.

(b) Legal Fees. If any contest or dispute shall arise between the Company and Executive regarding or as a result of any provision of this Agreement, the Company shall reimburse Executive for all legal fees and expenses reasonably incurred by Executive in connection with such contest or dispute, but only if Executive is successful in respect of substantially all of Executive's claims pursued or defended in connection with such contest or dispute. Such reimbursement shall be made as soon as practicable following the resolution of such contest or dispute (whether or not appealed).

16. Successors and Assigns.

(a) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance

21

satisfactory to Executive, to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such agreement prior to the effectiveness of an such succession shall be a breach of this Agreement and shall entitle Executive to compensation from the Company in the same amount and on the same terms as he would be entitled to hereunder if Executive terminated his employment hereunder within six (6) months of a Change in Control as set forth in Paragraph 9, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the date of termination. In the event of such a breach of this Agreement, the Notice of Termination shall specify such date as the date of termination. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to all or substantially all of its business and/or its assets as aforesaid which executes and delivers the agreement provided for in this Paragraph 16 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law. Any cash payments owed to Executive pursuant to this Paragraph 16 shall be paid to Executive in a single sum without discount for early payment immediately prior to the consummation of the transaction with such successor.

(b) This Agreement and all rights of Executive hereunder may be transferred only by will or the laws of descent and distribution. Upon Executive's death, this Agreement and all rights of Executive hereunder shall inure to the benefit of and be enforceable by Executive's beneficiary or beneficiaries, personal or legal representatives, or estate, to the extent any such person succeeds to Executive's

22

interests under this Agreement. Executive shall be entitled to select and change a beneficiary or beneficiaries to receive any benefit or compensation payable hereunder following Executive's death by giving Company written notice thereof. If Executive should die following the date of termination while any amounts would still be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons so appointed in writing by Executive, including, without limitation, under any applicable plan, or otherwise to his legal representatives or estate.

17. Timing of and No Duplication of Payments.

All payments payable to Executive pursuant to this Agreement shall be paid as soon as practicable after such amounts have become fully vested and determinable. In addition, Executive shall not be entitled to receive duplicate payments under any of the provisions of this Agreement.

18. Modification or Waiver.

No amendment, modification, waiver, termination or cancellation of this Agreement shall be binding or effective for any purpose unless it is made in a writing signed by the party against whom enforcement of such amendment, modification, waiver, termination or cancellation is sought. No course of dealing between or among the parties to this Agreement shall be deemed to affect or to modify, amend or discharge any provision or term of this Agreement. No delay on the part of the Company or Executive in the exercise of any of their respective rights or remedies shall

23

operate as a waiver thereof, and no single or partial exercise by the Company or Executive of any such right or remedy shall preclude other or further exercise thereof. A waiver of right or remedy on any one occasion shall not be construed as a bar to or waiver of any such right or remedy on any other occasion.

The respective rights and obligations of the parties hereunder shall survive the Executive's termination of employment and termination of this Agreement to the extent necessary for the intended preservation of such rights and obligations.

19. Notices.

SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT

THIS SECOND AMENDED AND RESTATED EMPLOYMENT AGREEMENT (the "Agreement") is entered into as of July 1, 1999, by and between Roger W. Thomas, an individual residing at 95 Mathews Drive, Bedminster, New Jersey 07921 ("Executive"), and Mack-Cali Realty Corporation, a Maryland corporation with offices at 11 Commerce Drive, Cranford, New Jersey 07016 (the "Company").

RECITALS

WHEREAS, Executive has served as Executive Vice President, General Counsel and Assistant Secretary of the Company pursuant to his prior employment agreement dated as of December 1997 (the "Prior Agreement") entered into as of the closing of the combination of Cali Realty Corporation with the Mack Companies (the "Mack Combination");

WHEREAS, the Company and the Executive wish to amend and restate the Prior Agreement in its entirety to provide for an award of Restricted Shares and a Tax Gross-Up Payment (as defined in sub-paragraph 4(c) below), to change the Employment Period (as defined in sub-paragraph 2(a) below) to (4) years and to amend the amount of the severance payment Executive may be eligible to receive upon termination of employment with the Company; and

WHEREAS, the Company desires to continue to employ Executive as Executive Vice President, General Counsel and Secretary, and Executive desires to continue to be employed by the Company as Executive Vice President, General Counsel and Secretary, pursuant to the amended and restated terms set forth herein and to restate the Prior Agreement in its entirety


NOW THEREFORE, in consideration of the premises and the mutual covenants and agreements set forth herein, the parties hereby agree as follows:

1. Employment.

The Company hereby agrees to employ Executive, and Executive hereby agrees to accept such employment during the period and upon the terms and conditions set forth in this Agreement.

2. Employment Period.

(a) Except as otherwise provided in this Agreement to the contrary, the terms and conditions of this Agreement shall be and remain in effect during the period of employment (the "Employment Period") established under this Paragraph 2. The initial Employment Period shall be for a term commencing on the date of this Agreement and ending on the fourth anniversary of the date of this Agreement provided, however, that commencing on the day after the date of this Agreement and on each day thereafter, the Employment Period shall be extended for one additional day so that a constant four (4) year Employment Period shall be in effect, unless (i) the Company or Executive elects not to extend the term of this Agreement by giving written notice to the other party in accordance with Paragraph 19, in which case, subject to the provisions of sub-paragraph 5(a)(iv) below, the term of this Agreement shall become fixed and shall end on the fourth anniversary of the date of such written notice ("Notice of Non-Renewal"), or
(ii) Executive's employment terminates hereunder.

(b) Notwithstanding anything contained herein to the contrary: (i) Executive's employment with the Company may be terminated by the Company or

2

Executive during the Employment Period, subject to the terms and conditions of this Agreement; and (ii) nothing in this Agreement shall mandate or prohibit a continuation of Executive's employment following the expiration of the Employment Period upon such terms and conditions as the Board of Directors of the Company (the "Board") and Executive may mutually agree.

(c) If Executive's employment with the Company is terminated, for purposes of this Agreement the term "Unexpired Employment Period" shall mean the period commencing on the date of such termination and ending on the last day of the Employment Period.

3. Services / Place of Employment.

(a) Services. During the Employment Period, Executive shall hold the positions of Executive Vice President, General Counsel and Secretary of the Company. Executive shall devote his best efforts and substantially all of his business time, skill and attention to the business of the Company (other than absences due to vacation, illness, disability or approved leave of absence), and shall perform such duties as are customarily performed by similar executive officers and as may be more specifically enumerated from time to time by the Chief Executive Officer; provided, however, that the foregoing is not intended to (a) preclude Executive from (i) owning and managing personal investments, including real estate investments, subject to the restrictions set forth in Paragraph 13 hereof or (ii) engaging in charitable activities and community affairs, or (b) restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to those properties

3

described in Schedule A, attached hereto, (the "Excluded Properties"), provided that the performance of the activities referred to in clauses (a) and (b) does not prevent Executive from devoting substantially all of his business time to the Company.

(b) Place of Employment. The principal place of employment of Executive shall be at the Company's principal executive offices in Cranford, New Jersey.

4. Compensation and Benefits.

(a) Salary. During the Employment Period, the Company shall pay Executive a minimum annual base salary in the amount of $325,000 (the "Annual Base Salary") payable in accordance with the Company's regular payroll practices. Executive's Annual Base Salary shall be reviewed annually in accordance with the policy of the Company from time to time and may be subject to upward adjustment based upon, among other things, Executive's performance, as determined in the sole discretion of the Chief Executive Officer. In no event shall Executive's Annual Base Salary in effect at a particular time be reduced without his prior written consent.

(b) Incentive Compensation/Bonuses. In addition, Executive shall be eligible for incentive compensation payable each year in such amounts as may be determined by the Option and Executive Compensation Committee of the Board (the "Compensation Committee"). Executive shall be entitled to receive such bonuses, restricted share awards and options to purchase shares of common stock, par value $0.01 per share, of the Company (the "Common Stock") as the Board or the Compensation Committee as the case may be shall approve, in its sole discretion,

4

including, without limitation, options, restricted share awards and bonuses contingent upon Executive's performance and the achievement of specified financial and operating objectives.

(c) Restricted Share Award/Tax Gross-Up Payment. Pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 1, 1998 (the "SOP"), Executive has been awarded a restricted share award of 22,031 shares of Common Stock ("Restricted Shares") as of July 1, 1999 (the "Restricted Share Award"). Executive shall be entitled to receive a tax gross-up payment (the "Tax Gross-Up Payment") from the Company with respect to each tax year in which Restricted Shares granted pursuant to the Restricted Share Award vest and are distributed to him. Each Tax Gross-Up Payment shall be a dollar amount equal to forty-three (43%) percent of the fair market value of the Restricted Shares at time of vesting, exclusive of dividends. In the event vesting occurs with respect to any Restricted Shares as a result of the achievement of the required performance goals, such payment shall be made as soon as practicable after a determination that the performance goals have been achieved but in no event later than the 90th day of the fiscal year of the Company immediately following the fiscal year as to which the performance goals were achieved. In the event vesting occurs for any other reason, including, without limitation, termination of Executive's employment by the Company without Cause or by Executive for Good Reason (but excluding a termination by the Company for Cause or a voluntary quit without Good Reason by Executive), such payment shall be made as soon as

5

practicable after the date of vesting but in no event later than the tenth
(10th) business day following such vesting.

(d) Taxes and Withholding. The Company shall have the right to deduct and withhold from all compensation all social security and other federal, state and local taxes and charges which currently are or which hereafter may be required by law to be so deducted and withheld.

(e) Additional Benefits. In addition to the compensation specified above and other benefits provided pursuant to this Paragraph 4, Executive shall be entitled to the following benefits:

(i) participation in the SOP, the Mack-Cali Realty Corporation
401(k) Savings and Retirement Plan (subject to statutory rules and maximum contributions and non-discrimination requirements applicable to 401(k) plans) and such other benefit plans and programs, including but not limited to restricted stock, phantom stock and/or unit awards, loan programs and any other incentive compensation plans or programs (whether or not employee benefit plans or programs), as maintained by the Company from time to time and made generally available to executives of the Company with such participation to be consistent with reasonable Company guidelines;

(ii) participation in any health insurance, disability insurance, paid vacation, group life insurance or other welfare benefit program made generally available to executives of the Company; and

(iii) reimbursement for reasonable business expenses incurred by Executive in furtherance of the interests of the Company including a monthly allowance of twelve hundred ($1,200) which is intended to cover the cost of local business-related travel expenses exclusive of amounts paid to third-parties (e.g. taxi service).

5. Termination of Employment and Change in Control.

6

(a) Executive's employment hereunder may be terminated during the Employment Period under the following circumstances:

(i) Cause. The Company shall have the right to terminate Executive's employment for Cause upon Executive's: (A) willful and continued failure to use best efforts to substantially perform his duties hereunder (other than any such failure resulting from Executive's incapacity due to physical or mental illness) for a period of thirty (30) days after written demand for substantial performance is delivered by the Company specifically identifying the manner in which the Company believes Executive has not substantially performed his duties; (B) willful misconduct and/or willful violation of Paragraph 11 hereof, which is materially economically injurious to the Company and the Partnership taken as a whole; (C) the willful violation of the provisions of Paragraph 13 hereof; or (D) conviction of, or plea of guilty to a felony. For purposes of this sub-paragraph 5(a), no act, or failure to act, on Executive's part shall be considered "willful" unless done, or omitted to be done, by him (I) not in good faith and (II) without reasonable belief that his action or omission was in furtherance of the interests of the Company.

(ii) Death. Executive's employment hereunder shall terminate upon his death.

(iii) Disability. The Company shall have the right to terminate Executive's employment due to "Disability" in the event that there is a determination by the Company, upon the advice of an independent qualified physician, reasonably acceptable to Executive, that Executive has become physically or mentally incapable of performing his duties under this Agreement and such disability has disabled Executive for a cumulative period of one hundred eighty (180) days within a twelve (12) month period.

(iv) Good Reason. Executive shall have the right to terminate his employment for "Good Reason": (A) upon the occurrence of any material breach of this Agreement by the Company which shall include but not be limited to; an assignment to Executive of duties materially and adversely inconsistent with Executive's status as Executive Vice President, General Counsel or Secretary or a material or adverse alteration in the nature of or diminution in Executive's duties and/or responsibilities, reporting obligations, titles or authority; (B) upon a reduction in Executive's Annual Base Salary or a material reduction in other benefits (except for bonuses or similar discretionary payments) as in effect at the time in

7

question, a failure to pay such amounts when due or any other failure by the Company to comply with Paragraph 4 hereof; (C) on or within six (6) months following the date a Notice of Non-Renewal is issued by the Company pursuant to Paragraph 2 hereof; (D) on or within six (6) months following a Change in Control (as hereinafter defined) in accordance with the provisions set forth in sub-paragraph 5(a)(vii) hereof; (E) upon any purported termination of Executive's employment for Cause which is not effected pursuant to the procedures of sub-paragraph 5(a)(i) (and for purposes of this Agreement, in the event of such failure to comply, no such purported termination shall be effective); or (F) upon the relocation of the Company's principal executive offices or Executive's own office location to a location more than thirty (30) miles away from Cranford, New Jersey.

(v) Without Cause. The Company shall have the right to terminate the Executive's employment hereunder without Cause subject to the terms and conditions of this Agreement.

(vi) Without Good Reason. The Executive shall have the right to terminate his employment hereunder without Good Reason subject to the terms and conditions of this Agreement.

(vii) Change in Control. Executive shall have the right to terminate his employment hereunder on or within six (6) months following a Change in Control. Such termination shall be deemed a termination for Good Reason hereunder. For purposes of this Agreement "Change in Control" shall mean that any of the following events has occurred: (A) any "person" or "group" of persons, as such terms are used in Sections 13 and 14 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), other than any employee benefit plan sponsored by the Company, becomes the "beneficial owner", as such term is used in Section 13 of the Exchange Act, (irrespective of any vesting or waiting periods) of (I) Common Stock or any class of stock convertible into Common Stock and/or (II) Common OP Units or preferred units or any other class of units convertible into Common OP Units, in an amount equal to twenty (20%) percent or more of the sum total of the Common Stock and the Common OP Units (treating all classes of outstanding stock, units or other securities convertible into stock units as if they were converted into Common Stock or Common OP Units as the case may be and then treating Common Stock and Common OP Units as if they were a single class) issued and outstanding immediately prior to such acquisition as if they were a single class and disregarding any equity raise in connection with

8

the financing of such transaction; (B) any Common Stock is purchased pursuant to a tender or exchange offer other than an offer by the Company; (C) the dissolution or liquidation of the Company or the consummation of any merger or consolidation of the Company or any sale or other disposition of all or substantially all of its assets, if the shareholders of the Company and unitholders of the Partnership taken as a whole and considered as one class immediately before such transaction own, immediately after consummation of such transaction, equity securities and partnership units possessing less than fifty (50%) percent of the surviving or acquiring company and partnership taken as a whole; or (D) a turnover, during any two (2) year period, of the majority of the members of the Board, without the consent of the remaining members of the Board as to the appointment of the new Board members.

(b) Notice of Termination. Any termination of Executive's employment by the Company or any such termination by Executive (other than on account of death) shall be communicated by written Notice of Termination to the other party hereto. For purposes of this Agreement, a "Notice of Termination" shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon and shall set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of Executive's employment under the provision so indicated. In the event of the termination of Executive's employment on account of death, written Notice of Termination shall be deemed to have been provided on the date of death.

6. Compensation Upon Termination of Employment By the Company for Cause or By Executive without Good Reason.

In the event the Company terminates Executive's employment for Cause or Executive terminates his employment without Good Reason, the Company shall pay Executive any unpaid Annual Base Salary at the rate then in effect accrued through and

9

including the date of termination. In addition, in such event, Executive shall be entitled (i) to receive any earned but unpaid incentive compensation or bonuses and (ii) to exercise any options which have vested and are exercisable in accordance with the terms of the applicable option grant agreement or plan, and (iii) to retain and/or receive any Restricted Shares which have vested as of the last day of the Company's fiscal year coincident or immediately preceding Executive's termination of employment and the corresponding Tax Gross-Up Payment (irrespective of whether the determination is made after Executive's termination of employment).

Except for any rights which Executive may have to unpaid salary amounts through and including the date of termination, earned but unpaid incentive compensation or bonuses, vested options, vested Restricted Shares and the corresponding Tax Gross-Up Payment, the Company shall have no further obligations hereunder following such termination. The aforesaid amounts shall be payable in full immediately upon such termination.

7. Compensation Upon Termination of Employment Upon Death or Disability.

In the event of termination of Executive's employment as a result of either Executive's death or Disability, the Company shall pay to Executive, his estate or his personal representative the aggregate of (i) a cash payment of two million five hundred thousand dollars ($2,500,000)in full immediately upon such termination (the "Fixed Amount") and (ii) reimbursement of expenses incurred prior to date of termination ("Expense Reimbursement"). Executive (and Executive's dependents) shall also receive continuation of health coverage through the end of the Unexpired Employment

10

Period on the same basis as health coverage is provided by the Company for active employees and as may be amended from time to time ("Medical Continuation").

In addition, all (A) incentive compensation payments or programs of any nature whether stock based or otherwise that are subject to a vesting schedule including, without limitation, the Restricted Share Award or any other restricted stock, phantom stock, units and any loan forgiveness arrangements granted to Executive ("Incentive Compensation") shall immediately vest as of the date of such termination ("Vested Incentive Compensation"), (B) options granted to Executive shall immediately vest as of the date of such termination (the "Vested Options") and Executive shall be entitled at the option of Executive, his estate or his personal representative, within one (1) year of the date of such termination, to exercise the Vested Options and/or other options which have vested (including, without limitation, all other options which have previously vested in accordance with the Prior Agreement, any applicable option grant agreement or plan) (the "Total Vested Options") and are exercisable in accordance with the terms of the applicable option grant agreement or plan and/or any other methods or procedures for exercise applicable to optionees or to require the Company (upon written notice delivered within one hundred eighty
(180) days following the date of Executive's termination) to repurchase all or any portion of Executive's vested options to purchase shares of Common Stock at a price equal to the difference between the Repurchase Fair Market Value (as hereinafter defined) of the shares of Common Stock for which the options to be repurchased are exercisable and the exercise price of such options as of the date of Executive's termination of employment (the "Vested Option Exercise Election"), and (C) the Tax Gross-Up Payment(s) applicable to the Restricted Share

11

Award shall vest and be paid to Executive at such time as provided in sub-paragraph 4(c) above (the "Vested Tax Gross-Up Payments"). In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

Except for any rights which Executive or Executive's estate in the event of Executive's death may have to all of the above including the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation (which, in the event of Executive's death, shall be provided to Executive's dependents), the Company shall have no further obligations hereunder following such termination.

For purposes of this Agreement, "Repurchase Fair Market Value" shall mean the average of the closing price on the New York Stock Exchange (or such other exchange on which the Common Stock is primarily traded) of the Common Stock on each of the trading days within the thirty (30) days immediately preceding the date of termination of Executive's employment.

8. Compensation Upon Termination of Employment By the Company Without Cause or By Executive for Good Reason.

In the event the Company terminates Executive's employment for any reason other than Cause or Executive terminates his employment for Good Reason, the Company shall pay to Executive and Executive shall be entitled to receive the aggregate of (i) the Fixed Amount and (ii) Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment,

12

Expense Reimbursement and Medical Continuation. In the event of a conflict between any Incentive Compensation grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control. Executive understands that any options exercised more than ninety (90) days following the date of his termination of employment which were granted as incentive stock options shall automatically be converted into non-qualified options.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement and Medical Continuation, the Company shall have no further obligations hereunder following such termination. The parties both agree that the agreement to make these payments was consideration and an inducement to obtain Executive's consent to enter into this Agreement. The payments are not a penalty and neither party will claim them to be a penalty. Rather, the payments represent a fair approximation of reasonable amounts due to Executive for the Employment Period.

9. Change in Control.

(a) Options. Any Incentive Compensation and options granted to Executive that have not vested as of the date of a Change in Control shall immediately vest upon the date of the Change in Control. Neither the occurrence of a Change in Control, nor the vesting in any options as a result thereof shall require Executive to exercise any options. In the event of a conflict between any Incentive Compensation

13

grant agreement or program or any option grant agreement or plan and this Agreement, the terms of this Agreement shall control.

(b) Upon Termination. In the event Executive terminates his employment on or following a Change in Control as set forth in sub-paragraph
5(a)(vii), the Company shall pay to Executive and Executive shall be entitled to all the payments and rights Executive would have had if Executive had terminated his employment with Good Reason as set forth in Paragraph 8.

Except for any rights which Executive may have to the Fixed Amount, Vested Incentive Compensation, Total Vested Options (including, without limitation, by acceleration in accordance with sub-paragraph 9(a)) and the Vested Option Exercise Election, the Vested Tax Gross-Up Payment, Expense Reimbursement, Medical Continuation and the Excise Tax Gross Up set forth in subparagraph 9(c), the Company shall have no further obligations hereunder following such termination.

(c) Excise Tax Gross Up. In addition, if it is determined by an independent accountant mutually acceptable to the Company and Executive that as a result of any payment in the nature of compensation made by the Company to (or for the benefit of) Executive pursuant to this Agreement or otherwise, an excise tax may be imposed on Executive pursuant to Section 4999 of the Code (or any successor provisions), the Company shall pay Executive in cash an amount equal to X determined under the following formula: (the "Excise Tax Gross Up"):

E x P

X = --------------------------------

1-[(FI x (1-SLI)) + SLI + E + M]

where

14

E     =     the rate at which the excise tax is assessed under
            Section 4999 of the Code (or any successor provisions);

P     =     the amount with respect to which such excise tax is
            assessed, determined without regard to the Excise Tax
            Gross Up;

FI    =     the highest effective marginal rate of income tax
            applicable to Executive under the Code for the taxable
            year in question (taking into account any phase-out or
            loss of deductions, personal exemptions or other similar
            adjustments);

SLI   =     the sum of the highest effective marginal rates of
            income tax applicable to Executive under all applicable
            state and local laws for the taxable year in question
            (taking into account any phase-out or loss of
            deductions, personal exemptions and other similar
            adjustments); and

M     =     the highest marginal rate of Medicare tax applicable to
            Executive under the Code for the taxable year in
            question.

With respect to any payment in the nature of compensation that is made to (or for the benefit of) Executive under the terms of this Agreement or otherwise and on which an excise tax under Section 4999 of the Code (or any successor provisions) may be assessed, the payment determined under this sub-paragraph 9(c) shall be paid to Executive at the time of the Change in Control but prior to the consummation of the transaction with any successor. It is the intention of the parties that the Company provide Executive with a full tax gross-up under the provisions of this sub-paragraph, so that on a net after-tax basis, the result to Executive shall be the same as if the excise tax under Section 4999 of the Code (or any successor provisions) had not been imposed. The Excise Tax Gross Up may be adjusted if alternative minimum tax rules are applicable to Executive.

15

10. Mitigation / Effect on Employee Benefit Plans and Programs.

(a) Mitigation. Executive shall not be required to mitigate amounts payable under this Agreement by seeking other employment or otherwise, and there shall be no offset against amounts due Executive under this Agreement on account of subsequent employment. Amounts owed to Executive under this Agreement shall not be offset by any claims the Company may have against Executive and such payment shall not be affected by any other circumstances, including, without limitation, any counterclaim, recoupment, defense, or other right which the Company may have against Executive or others.

(b) Effect on Employee Benefit Programs. The termination of Executive's employment hereunder, whether by the Company or Executive, shall have no effect on the rights and obligations of the parties hereto under the Company's (i) welfare benefit plans including, without limitation, Medical Continuation as provided for herein and, health coverage thereafter but only to the extent required by law, and on the same basis applicable to other employees and (ii) 401(k) Plan but only to the extent required by law and pursuant to the terms of the 401(k) Plan.

11. Confidential Information.

(a) Executive understands and acknowledges that during his employment with the Company, he will be exposed to Confidential Information (as defined below), all of which is proprietary and which will rightfully belong to the Company. Executive shall hold in a fiduciary capacity for the benefit of the Company such Confidential Information obtained by Executive during his employment with the

16

Company and shall not, directly or indirectly, at any time, either during or after his employment with the Company, without the Company's prior written consent, use any of such Confidential Information or disclose any of such Confidential Information to any individual or entity other than the Company or its employees, attorneys, accountants, financial advisors, consultants, or investment bankers except as required in the performance of his duties for the Company or as otherwise required by law. Executive shall take all reasonable steps to safeguard such Confidential Information and to protect such Confidential Information against disclosure, misuse, loss or theft.

(b) The term "Confidential Information" shall mean any information not generally known in the relevant trade or industry or otherwise not generally available to the public, which was obtained from the Company or its predecessors or which was learned, discovered, developed, conceived, originated or prepared during or as a result of the performance of any services by Executive on behalf of the Company or its predecessors. For purposes of this Paragraph 11, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

12. Return of Documents.

Except for such items which are of a personal nature to Executive (e.g., daily business planner), all writings, records, and other documents and things containing any Confidential Information shall be the exclusive property of the Company, shall not be copied, summarized, extracted from, or removed from the premises of the Company,

17

except in pursuit of the business of the Company and at the direction of the Company, and shall be delivered to the Company, without retaining any copies, upon the termination of Executive's employment or at any time as requested by the Company.

13. Noncompete.

Executive agrees that:

(a) During the Employment Period and, in the event (i) the Company terminates Executive's employment for Cause, or (ii) Executive terminates his employment without Good Reason, for a one (1) year period thereafter, Executive shall not, directly or indirectly, within the continental United States, engage in, or own, invest in, manage or control any venture or enterprise primarily engaged in any office-service, flex, or office property development, acquisition or management activities without regard to whether or not such activities compete with the Company. Nothing herein shall prohibit Executive from being a passive owner of not more than five percent (5%) of the outstanding stock of any class of securities of a corporation or other entity engaged in such business which is publicly traded, so long as he has no active participation in the business of such corporation or other entity. Moreover, the foregoing limitations shall not be deemed to restrict or otherwise limit Executive from conducting real estate development, acquisition or management activities with respect to the Excluded Properties, if any, provided that during the Employment Period the performance of such activities does not prevent Executive from devoting substantially all of his business time to the Company.

18

(b) If, at the time of enforcement of this Paragraph 13, a court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable, the parties agree that reasonable maximum duration, scope, area or other restrictions may be substituted by such court for the stated duration, scope, area or other restrictions and upon substitution by such court, this Agreement shall be automatically modified without further action by the parties hereto.

(c) For purposes of this Paragraph 13, the Company shall be deemed to include any entity which is controlled, directly or indirectly, by the Company and any entity of which a majority of the economic interest is owned, directly or indirectly, by the Company.

14. Remedies.

The parties hereto agree that the Company would suffer irreparable harm from a breach by Executive of any of the covenants or agreements contained in Paragraphs 11, 12 or 13 of this Agreement. Therefore, in the event of the actual or threatened breach by Executive of any of the provisions of Paragraphs 11, 12 or 13 of this Agreement, the Company may, in addition and supplementary to other rights and remedies existing in its favor, apply to any court of law or equity of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce or prevent any violation of the provisions thereof.

15. Indemnification/Legal Fees.

19

(a) Indemnification. In the event the Executive is made party or threatened to be made a party to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "Proceeding"), by reason of Executive's employment with or serving as an officer or director of the Company, whether or not the basis of such Proceeding is alleged action in an official capacity, the Company shall indemnify, hold harmless and defend Executive to the fullest extent authorized by Maryland law, as the same exists and may hereafter be amended, against any and all claims, demands, suits, judgments, assessments and settlements including all expenses incurred or suffered by Executive in connection therewith (including, without limitation, all legal fees incurred using counsel reasonably acceptable to Executive) and such indemnification shall continue as to Executive even after Executive is no longer employed by the Company and shall inure to the benefit of his heirs, executors, and administrators. Expenses incurred by Executive in connection with any Proceeding shall be paid by the Company in advance upon request of Executive that the Company pay such expenses; but, only in the event that Executive shall have delivered in writing to the Company an undertaking to reimburse the Company for expenses with respect to which Executive is not entitled to indemnification. The provisions of this Paragraph shall remain in effect after this Agreement is terminated irrespective of the reasons for termination. The indemnification provisions of this Paragraph shall not supersede or reduce any indemnification provided to Executive under any separate agreement, or the by-laws of the Company since it is intended that this Agreement shall expand and extend the Executive's rights to receive indemnity.

20

(b) Legal Fees. If any contest or dispute shall arise between the Company and Executive regarding or as a result of any provision of this Agreement, the Company shall reimburse Executive for all legal fees and expenses reasonably incurred by Executive in connection with such contest or dispute, but only if Executive is successful in respect of substantially all of Executive's claims pursued or defended in connection with such contest or dispute. Such reimbursement shall be made as soon as practicable following the resolution of such contest or dispute (whether or not appealed).

16. Successors and Assigns.

(a) The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company, by agreement in form and substance satisfactory to Executive, to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Failure of the Company to obtain such agreement prior to the effectiveness of an such succession shall be a breach of this Agreement and shall entitle Executive to compensation from the Company in the same amount and on the same terms as he would be entitled to hereunder if Executive terminated his employment hereunder within six (6) months of a Change in Control as set forth in Paragraph 9, except that for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed the date of termination. In the event of such a breach of this Agreement, the Notice of Termination

21

shall specify such date as the date of termination. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to all or substantially all of its business and/or its assets as aforesaid which executes and delivers the agreement provided for in this Paragraph 16 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law. Any cash payments owed to Executive pursuant to this Paragraph 16 shall be paid to Executive in a single sum without discount for early payment immediately prior to the consummation of the transaction with such successor.

(b) This Agreement and all rights of Executive hereunder may be transferred only by will or the laws of descent and distribution. Upon Executive's death, this Agreement and all rights of Executive hereunder shall inure to the benefit of and be enforceable by Executive's beneficiary or beneficiaries, personal or legal representatives, or estate, to the extent any such person succeeds to Executive's interests under this Agreement. Executive shall be entitled to select and change a beneficiary or beneficiaries to receive any benefit or compensation payable hereunder following Executive's death by giving Company written notice thereof. If Executive should die following the date of termination while any amounts would still be payable to him hereunder if he had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to such person or persons so appointed in writing by Executive, including, without limitation, under any applicable plan, or otherwise to his legal representatives or estate.

17. Timing of and No Duplication of Payments.

22

All payments payable to Executive pursuant to this Agreement shall be paid as soon as practicable after such amounts have become fully vested and determinable. In addition, Executive shall not be entitled to receive duplicate payments under any of the provisions of this Agreement.

18. Modification or Waiver.

No amendment, modification, waiver, termination or cancellation of this Agreement shall be binding or effective for any purpose unless it is made in a writing signed by the party against whom enforcement of such amendment, modification, waiver, termination or cancellation is sought. No course of dealing between or among the parties to this Agreement shall be deemed to affect or to modify, amend or discharge any provision or term of this Agreement. No delay on the part of the Company or Executive in the exercise of any of their respective rights or remedies shall operate as a waiver thereof, and no single or partial exercise by the Company or Executive of any such right or remedy shall preclude other or further exercise thereof. A waiver of right or remedy on any one occasion shall not be construed as a bar to or waiver of any such right or remedy on any other occasion.

The respective rights and obligations of the parties hereunder shall survive the Executive's termination of employment and termination of this Agreement to the extent necessary for the intended preservation of such rights and obligations.

19. Notices.

23

All notices or other communications required or permitted hereunder shall be made in writing and shall be deemed to have been duly given if delivered by hand or delivered by a recognized delivery service or mailed, postage prepaid, by express, certified or registered mail, return receipt requested, and addressed to the Chief Executive Officer of the Company or Executive, as applicable, at the address set forth above (or to such other address as shall have been previously provided in accordance with this Paragraph 19).

20. Governing Law.

This agreement will be governed by and construed in accordance with the laws of the State of New Jersey except as to Paragraph 15(a), without regard to principles of conflicts of laws thereunder.

21. Severability.

Whenever possible, each provision and term of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision or term of this Agreement shall be held to be prohibited by or invalid under such applicable law, then, subject to the provisions of sub-paragraph 13(b) above, such provision or term shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or affecting in any manner whatsoever the remainder of such provisions or term or the remaining provisions or terms of this Agreement.

22. Legal Representation.

24

Each of the Company and Executive have been represented by counsel with respect to this Agreement.

23. Counterparts.

This Agreement may be executed in separate counterparts, each of which is deemed to be an original and both of which taken together shall constitute one and the same agreement.

24. Headings.

The headings of the Paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute a part hereof and shall not affect the construction or interpretation of this Agreement.

25. Entire Agreement.

This Agreement constitutes the entire agreement of the parties with respect to the subject matter hereof and supersedes all other prior agreements and undertakings, both written and oral, among the parties with respect to the subject matter hereof. The parties recognize that the Prior Agreement has been amended and restated in its entirety by this Agreement and the terms of the Prior Agreement are of no further force and effect.

26. Survival of Agreements.

The covenants made in Paragraphs 5 through 15 and 21 each shall survive the termination of this Agreement.

25

IN WITNESS WHEREOF, the undersigned have executed this Agreement as of the date first above written.

MACK-CALI REALTY CORPORATION

RESTRICTED SHARE AWARD AGREEMENT

MITCHELL E. HERSH


AGREEMENT EVIDENCING THE GRANT
OF A RESTRICTED SHARE AWARD PURSUANT
TO THE EMPLOYEE STOCK OPTION PLAN
OF MACK-CALI REALTY CORPORATION

AGREEMENT ("Agreement") effective as of July 1, 1999, ("Grant Date") by and between Mack-Cali Realty Corporation (the "Company") and Mitchell E. Hersh ("Recipient").

WHEREAS, pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 11, 1998 (the "Plan"), the Company hereby awards shares of the Company's common stock, par value $.01 per share ("Common Stock") to the Recipient subject to such terms, conditions, and restrictions (hereinafter, "Restricted Share Award") as set forth in the Plan, this Agreement, and the Amended and Restated Employment Agreement dated as of July 1, 1999 by and between the Company and Recipient (the "Employment Agreement"), and

WHEREAS, Recipient has agreed under the amended terms of the Employment Agreement to change his employment period to four (4) years, and to amend the amount of the severance payment Recipient may be eligible to receive upon termination of employment with the Company, and

WHEREAS, upon the vesting of Restricted Shares, Recipient is also entitled to receive a tax gross-up from the Company under the amended terms of the Employment Agreement to enable Recipient to retain as many shares of Common Stock as possible,

NOW THEREFORE, the parties hereto hereby agree as follows:


1. Award of Shares of Restricted Stock.

Pursuant to the Plan, the Committee hereby awards to the Recipient, effective as of the Grant Date, a Restricted Share Award representing the conditional receipt of 62,500 shares of Common Stock ("Restricted Shares") at no out-of-pocket cost to the Recipient subject to the terms, conditions and restrictions set forth herein. Except for defined terms set forth in Section 4 below, capitalized terms not otherwise defined in this Agreement shall be as defined in the Plan.

2. Award Restrictions.

(a) General Rules. Ownership of Restricted Shares shall not vest in the Recipient, and shall be subject to forfeiture until the conditions of Section 2(b) and (c) or Section 4 are fully satisfied. For purposes of this Agreement, the following concepts shall be defined as follows: (i) the lapse of restrictions on the Recipient's rights with respect to the Restricted Shares granted hereunder shall be referred to as "Vesting"; (ii) the period between the Grant Date and the date of Vesting shall be referred to as the "Vesting Period"; and (iii) the date Vesting occurs shall be referred to as the "Vesting Date."

(b) Vesting. An aggregate of 62,500 Restricted Shares may vest in the Recipient and vest on either a year by year basis over a five year Vesting Period or on a cumulative basis over a seven year maximum Vesting Period. The number of Restricted Shares scheduled to be vested and earned on each Vesting Date on a year by year basis provided the Performance Goals specified in Section 2(c) below are satisfied is as follows:

-2-

Restricted Shares                Vesting Date
-----------------                ------------

        9,375                  January 1, 2000
        9,375                  January 1, 2001
       12,500                  January 1, 2002
       15,625                  January 1, 2003
       15,625                  January 1, 2004

The Vesting Date for this Agreement shall be each January 1st through and including January 1, 2006. In determining the number of Restricted Shares which are earned and vested, fractional shares shall be rounded down to the nearest whole number and shall be aggregated and earned on the next Vesting Date.

(c) Performance Goals. (i) The Restricted Shares shall vest on the applicable Vesting Date on a year by year basis provided one of the following financial tests ("Financial Tests") is met for the measurement period ending on the last day of the Company's fiscal year immediately preceding such Vesting Date: (A) the Company achieves an eight percent (8%) funds from operations per common share ("FFO") increase, or (B) shareholders receive a twelve and three quarters percent (12.75%) total return (dividends, assuming reinvestment upon applicable payment date, plus stock appreciation per share of Common Stock). For purposes of this Agreement, FFO shall mean (i) net income
(loss) before minority interest of unit holders, computed in accordance with generally accepted accounting principles ("GAAP"), excluding the effect of straight lining of rents, gains (or losses) from debt restructuring, other extraordinary and significant non-recurring items, and gains (or losses) on sale of property and other property-related valuation allowances, plus real estate related depreciation and amortization, as calculated in accordance with the National Association of Real Estate Investment Trusts definition published in March 1995 after

-3-

adjustment for straight lining of rents and as applied in accordance with the accounting practices and policies of the Company in effect from time to time on a consistent basis to the entire Vesting Period, divided by (ii) the sum of (A) the diluted weighted average number of outstanding shares of Common Stock and (B) the diluted weighted average number of outstanding common limited partnership units of Mack-Cali Realty, L.P., a Delaware limited partnership of which the Company is the sole general partner, for the applicable period with such calculations being made all before the effect on FFO and diluted common shares/common limited partnership units resulting from certain non-recurring cash payments made pursuant to certain written employment agreements and from the vesting of restricted share awards and other similar plans or compensation arrangements for the applicable period.

(ii) In the event that neither of the Financial Tests above is satisfied for the fiscal year of the Company corresponding to the applicable Vesting Date ("Non-Achievement Year"), any Restricted Shares that failed to vest under the annual performance goal criteria on such Date may vest on such Date or on a subsequent Vesting Date provided the test described below is satisfied (the "Cumulative Test"). The Cumulative Test shall be applied at the end of the Non-Achievement Year or any subsequent fiscal year ("Catch-Up Year") with respect to any Non-Achievement Year provided a Financial Test was satisfied in a prior fiscal year or is satisfied in a Catch-Up Year, by applying the aggregate Financial Test percentages and the performance goal requirement on a cumulative basis beginning with the first fiscal year of the Vesting Period and ending with the Non-Achievement Year or the Catch-Up Year, as applicable. In the event the Cumulative Test is satisfied (i.e., the

-4-

aggregate increase in FFO or aggregate total return is not less than the minimum percentage required to satisfy the Financial Test after taking into account the applicable Non-Achievement Year), the Restricted Shares that failed to vest in the Non-Achievement Year shall automatically vest on the Vesting Date applicable to the Non-Achievement Year or the Catch-Up Year, as the case may be. For example, if vesting occurred in years one (1) and two (2), year three (3) is a Non-Achievement Year, and the Cumulative Test is met for the Non-Achievement Year (i.e., either FFO is not less than twenty-four (24%) percent or the aggregate return is not less than thirty-eight and one-quarter (38.25%) percent) vesting would occur on the Vesting Date applicable to the Non-Achievement Year. In the event the Cumulative Test is not met in the Non-Achievement Year, one of the Financial Tests is met in year four (4), the Cumulative Test may be used. Under this scenario, vesting in that portion of the Restricted Stock Award scheduled to vest in year three (3) will occur in year four (4) if either the aggregate FFO is not less than thirty-two percent (32%) or the aggregate total return is not less than fifty-one percent (51%) at the end of the fourth (4th) fiscal year. Rules for Application of the Cumulative Test: (a) the Cumulative Test will be applied first at the end of any Non-Achievement Year, (b) it is not necessary for any Catch-Up Year to immediately succeed a Non-Achievement Year in order for the Cumulative Test to be applicable as long as the Catch-Up Year occurs during the Vesting Period, (c) if two (2) or more Non-Achievement Years have occurred during the Vesting Period and remain non-vested, in the event that the Cumulative Test is met on a partial basis so that at least one (1) full year's vesting may occur, the Restricted Share Award granted with respect to the last Non-Achievement Year that has occurred, shall vest first and any

-5-

excess shall be credited to another Non-Achievement Year and (d) the Cumulative Test may be met on a partial basis by aggregating percentages in excess of the minimum annual requirement from more than one (1) fiscal year in the Vesting Period. For example, if vesting occurred in year one (1) and the FFO is sixteen (16%) percent, years two (2) and three (3) are Non-Achievement Years with a loss in year two (2) of two (2%) percent and year three (3) the FFO is four (4%) percent, the Restricted Shares awarded with respect to year three (3) would vest under the Cumulative Test and two (2%) percent of the remaining FFO would be available to be used in year two (2) or any other year (e.g., in the event that FFO were fourteen (14%) percent in year four (4), the Restricted Shares applicable to year two (2) would also vest. In the alternative, if FFO were six (6%) percent in year four (4), year four (4) would vest and year two (2) would remain a Non-Achievement Year). Notwithstanding any contrary provisions contained in this Section 2(c) and subject to Section 4 below, any Restricted Shares that have not been earned and vested by January 1, 2004 on a year by year basis or by January 1, 2006 pursuant to the Cumulative Test shall automatically be canceled and forfeited.

(d) Lapse of Restrictions. Upon the Vesting of Restricted Shares, the Recipient shall own the Shares free and clear of all restrictions imposed by this Agreement and the Recipient shall be free to hold or dispose of such Shares in his discretion, subject to applicable federal and state law or regulations.

(e) Prohibition Against Assignment. During the Vesting Period, the Restricted Shares may not be transferred or encumbered by the Recipient by means of sale, assignment, mortgage, transfer, exchange, pledge, or otherwise. The

-6-

levy of any execution, attachment, or similar process upon the Restricted Shares shall be null and void.

3. Stock Certificates.

(a) Certificates. Restricted Shares shall be evidenced by one or more stock certificates registered in the name of the Recipient or a nominee or nominees therefor. Prior to Vesting, the Company shall prepare and issue separate certificates for the Restricted Shares scheduled to vest in each year (the "Share Certificates"), which shall be registered in the name of the Recipient and which shall bear such restrictive legend or legends (if any) as the Company may deem necessary or desirable under any applicable law.

(b) Stock Powers. The Recipient shall execute and deliver to the designee of the Company (the "Designee") stock powers corresponding to the Share Certificates designating the Company as the transferee of an unspecified number of Shares, which stock powers may be completed by the Designee as specified herein. The Recipient and the Company each waive the requirement that the signature of the Recipient on the stock powers be guaranteed. Upon receipt of a copy of this Agreement and the stock powers, each signed by the Recipient, the Designee shall promptly notify the proper officers of the Company and the Share Certificates and stock powers shall be held by the Company in accordance with the terms of this Agreement.

(c) Effect of Vesting. Upon Vesting, the Company shall cause to be delivered to the Recipient (i) a certificate for the Shares which have vested free and clear of restrictive legends and (ii) any stock powers signed hereunder by the Recipient remaining in its possession related to the vested shares. In the event that

-7-

the Recipient dies before delivery of the certificate, such certificate shall be delivered to, and registered in the name of, the Recipient's beneficiary or estate, as the case may be.

(d) Rights of Stockholder. Except as otherwise provided in
Section 2 and this Section 3, during the Vesting Period and after the certificates for the Restricted Shares have been issued, the Recipient shall be entitled to all rights of a stockholder of the Company, including the right to vote and the right to receive dividends, with respect to the Restricted Shares subject to this Agreement. Subject to applicable withholding requirements, if any, dividends on the Restricted Shares shall be paid to the Recipient when earned and payable.

(e) Power of Designee. The Designee is hereby authorized by the Recipient to utilize the stock power delivered by the Recipient to transfer all forfeited Shares to the Company upon receipt of instructions from a duly authorized representative of the Company.

4. Termination of Employment; Change in Control.

(a) Termination Due to Disability, Death or for Good Reason; Change in Control. Unless otherwise provided in the Employment Agreement and notwithstanding any provision of the Plan to the contrary, if the Recipient terminates employment with the Company due to Disability, death, for Good Reason or a termination initiated by the Company without Cause, all Restricted Shares subject to this Agreement and held by, or on behalf of, the Recipient shall be deemed earned and vested as of the Recipient's last day of employment with the Company. In addition, unless otherwise provided in the Employment Agreement and notwithstanding any

-8-

provision of the Plan to the contrary, all Restricted Shares subject to this Agreement and held by the Recipient on the date a Change in Control occurs shall be deemed earned and vested as of such date.

(b) Termination for Any Other Reason. Unless otherwise provided in the Employment Agreement, if the Recipient's employment with the Company terminates prior to January 1, 2006 for reasons other than Disability, death, a termination initiated by the Company without Cause or for Good Reason or as a result of a Change in Control, any Restricted Shares subject to this Agreement that have not been earned and vested prior to the Recipient's termination of employment shall be immediately forfeited on the last day of the Recipient's employment with the Company.

5. Withholding.

In connection with the delivery of any stock certificates, or the making of any payment in accordance with the provisions of this Agreement, the Company shall withhold Shares or cash amounts (for fractional Shares) equal to the taxes then required by applicable federal, state and local law to be so withheld.

6. Adjustments for Capital Changes.

In the event of any change in the outstanding shares of Common Stock of the Company by reason of any stock dividend or split, recapitalization, merger, consolidation, spin-off, reorganization, combination or exchange of shares, or other similar corporate change, or other increase or decrease in such shares effected without receipt or payment of consideration by the Company, a duly authorized representative of the Company shall adjust the number of Restricted Shares granted pursuant to the

-9-

Plan and this Agreement to prevent dilution or enlargement of the rights granted to the Recipient.

7. No Right to Continued Employment.

Nothing in this Agreement shall confer on the Recipient any right to continue as an employee of the Company or in any way affect the Company's or any subsidiary's right to terminate the Recipient's employment at any time.

8. Notice.

Any notice to the Company hereunder shall be in writing addressed to:

Mack-Cali Realty Corporation 11 Commerce Drive
Cranford, New Jersey 07016

Attn: Timothy M. Jones
President

Any notice to the Recipient hereunder shall be in writing addressed to:

(a) Entire Agreement. This Agreement contains the entire understanding of the parties and shall not be modified or amended except in writing and duly signed by each of the parties hereto. No waiver by either party of any default under this Agreement shall be deemed a waiver of any later default thereof.

(b) Effect of Employment Agreement. In the event the Employment Agreement with the Company contains additional rights, duties and/or

-10-

obligations with respect to the Recipient, such terms and conditions shall govern the Recipient's Restricted Share Award as if such terms and conditions had been set forth herein; and in the event of any conflict or inconsistency between the terms of the Employment Agreement or this Agreement, the terms and conditions of the Employment Agreement shall control.

aggregate increase in FFO or aggregate total return is not less than the minimum percentage required to satisfy the Financial Test after taking into account the applicable Non-Achievement Year), the Restricted Shares that failed to vest in the Non-Achievement Year shall automatically vest on the Vesting Date applicable to the Non-Achievement Year or the Catch-Up Year, as the case may be. For example, if vesting occurred in years one (1) and two (2), year three (3) is a Non-Achievement Year, and the Cumulative Test is met for the Non-Achievement Year (i.e., either FFO is not less than twenty-four (24%) percent or the aggregate return is not less than thirty-eight and one-quarter (38.25%) percent) vesting would occur on the Vesting Date applicable to the Non-Achievement Year. In the event the Cumulative Test is not met in the Non-Achievement Year, one of the Financial Tests is met in year four (4), the Cumulative Test may be used. Under this scenario, vesting in that portion of the Restricted Stock Award scheduled to vest in year three (3) will occur in year four (4) if either the aggregate FFO is not less than thirty-two percent (32%) or the aggregate total return is not less than fifty-one percent (51%) at the end of the fourth (4th) fiscal year. Rules for Application of the Cumulative Test: (a) the Cumulative Test will be applied first at the end of any Non-Achievement Year, (b) it is not necessary for any Catch-Up Year to immediately succeed a Non-Achievement Year in order for the Cumulative Test to be applicable as long as the Catch-Up Year occurs during the Vesting Period, (c) if two (2) or more Non-Achievement Years have occurred during the Vesting Period and remain non-vested, in the event that the Cumulative Test is met on a partial basis so that at least one (1) full year's vesting may occur, the Restricted Share Award granted with respect to the last Non-Achievement Year that has occurred, shall vest first and any

-5-

excess shall be credited to another Non-Achievement Year and (d) the Cumulative Test may be met on a partial basis by aggregating percentages in excess of the minimum annual requirement from more than one (1) fiscal year in the Vesting Period. For example, if vesting occurred in year one (1) and the FFO is sixteen (16%) percent, years two (2) and three (3) are Non-Achievement Years with a loss in year two (2) of two (2%) percent and year three (3) the FFO is four (4%) percent, the Restricted Shares awarded with respect to year three (3) would vest under the Cumulative Test and two (2%) percent of the remaining FFO would be available to be used in year two (2) or any other year (e.g., in the event that FFO were fourteen (14%) percent in year four (4), the Restricted Shares applicable to year two (2) would also vest. In the alternative, if FFO were six (6%) percent in year four (4), year four (4) would vest and year two (2) would remain a Non-Achievement Year). Notwithstanding any contrary provisions contained in this Section 2(c) and subject to Section 4 below, any Restricted Shares that have not been earned and vested by January 1, 2004 on a year by year basis or by January 1, 2006 pursuant to the Cumulative Test shall automatically be canceled and forfeited.

(d) Lapse of Restrictions. Upon the Vesting of Restricted Shares, the Recipient shall own the Shares free and clear of all restrictions imposed by this Agreement and the Recipient shall be free to hold or dispose of such Shares in his discretion, subject to applicable federal and state law or regulations.

(e) Prohibition Against Assignment. During the Vesting Period, the Restricted Shares may not be transferred or encumbered by the Recipient by means of sale, assignment, mortgage, transfer, exchange, pledge, or otherwise. The

-6-

levy of any execution, attachment, or similar process upon the Restricted Shares shall be null and void.

3. Stock Certificates.

(a) Certificates. Restricted Shares shall be evidenced by one or more stock certificates registered in the name of the Recipient or a nominee or nominees therefor. Prior to Vesting, the Company shall prepare and issue separate certificates for the Restricted Shares scheduled to vest in each year (the "Share Certificates"), which shall be registered in the name of the Recipient and which shall bear such restrictive legend or legends (if any) as the Company may deem necessary or desirable under any applicable law.

(b) Stock Powers. The Recipient shall execute and deliver to the designee of the Company (the "Designee") stock powers corresponding to the Share Certificates designating the Company as the transferee of an unspecified number of Shares, which stock powers may be completed by the Designee as specified herein. The Recipient and the Company each waive the requirement that the signature of the Recipient on the stock powers be guaranteed. Upon receipt of a copy of this Agreement and the stock powers, each signed by the Recipient, the Designee shall promptly notify the proper officers of the Company and the Share Certificates and stock powers shall be held by the Company in accordance with the terms of this Agreement.

(c) Effect of Vesting. Upon Vesting, the Company shall cause to be delivered to the Recipient (i) a certificate for the Shares which have vested free and clear of restrictive legends and (ii) any stock powers signed hereunder by the Recipient remaining in its possession related to the vested shares. In the event that the

-7-

Recipient dies before delivery of the certificate, such certificate shall be delivered to, and registered in the name of, the Recipient's beneficiary or estate, as the case may be.

(d) Rights of Stockholder. Except as otherwise provided in
Section 2 and this Section 3, during the Vesting Period and after the certificates for the Restricted Shares have been issued, the Recipient shall be entitled to all rights of a stockholder of the Company, including the right to vote and the right to receive dividends, with respect to the Restricted Shares subject to this Agreement. Subject to applicable withholding requirements, if any, dividends on the Restricted Shares shall be paid to the Recipient when earned and payable.

(e) Power of Designee. The Designee is hereby authorized by the Recipient to utilize the stock power delivered by the Recipient to transfer all forfeited Shares to the Company upon receipt of instructions from a duly authorized representative of the Company.

4. Termination of Employment; Change in Control.

(a) Termination Due to Disability, Death or for Good Reason; Change in Control. Unless otherwise provided in the Employment Agreement and notwithstanding any provision of the Plan to the contrary, if the Recipient terminates employment with the Company due to Disability, death, for Good Reason or a termination initiated by the Company without Cause, all Restricted Shares subject to this Agreement and held by, or on behalf of, the Recipient shall be deemed earned and vested as of the Recipient's last day of employment with the Company. In addition, unless otherwise provided in the Employment Agreement and notwithstanding any

-8-

provision of the Plan to the contrary, all Restricted Shares subject to this Agreement and held by the Recipient on the date a Change in Control occurs shall be deemed earned and vested as of such date.

(b) Termination for Any Other Reason. Unless otherwise provided in the Employment Agreement, if the Recipient's employment with the Company terminates prior to January 1, 2006 for reasons other than Disability, death, a termination initiated by the Company without Cause or for Good Reason or as a result of a Change in Control, any Restricted Shares subject to this Agreement that have not been earned and vested prior to the Recipient's termination of employment shall be immediately forfeited on the last day of the Recipient's employment with the Company.

5. Withholding.

In connection with the delivery of any stock certificates, or the making of any payment in accordance with the provisions of this Agreement, the Company shall withhold Shares or cash amounts (for fractional Shares) equal to the taxes then required by applicable federal, state and local law to be so withheld.

6. Adjustments for Capital Changes.

In the event of any change in the outstanding shares of Common Stock of the Company by reason of any stock dividend or split, recapitalization, merger, consolidation, spin-off, reorganization, combination or exchange of shares, or other similar corporate change, or other increase or decrease in such shares effected without receipt or payment of consideration by the Company, a duly authorized representative of the Company shall adjust the number of Restricted Shares granted pursuant to the

-9-

Plan and this Agreement to prevent dilution or enlargement of the rights granted to the Recipient.

7. No Right to Continued Employment.

Nothing in this Agreement shall confer on the Recipient any right to continue as an employee of the Company or in any way affect the Company's or any subsidiary's right to terminate the Recipient's employment at any time.

Any notice to the Company hereunder shall be in writing addressed to:

MACK-CALI REALTY CORPORATION

RESTRICTED SHARE AWARD AGREEMENT

JOHN R. CALI


AGREEMENT EVIDENCING THE GRANT
OF A RESTRICTED SHARE AWARD PURSUANT
TO THE EMPLOYEE STOCK OPTION PLAN
OF MACK-CALI REALTY CORPORATION

AGREEMENT ("Agreement") effective as of July 1, 1999, ("Grant Date") by and between Mack-Cali Realty Corporation (the "Company") and John R. Cali ("Recipient").

WHEREAS, pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 11, 1998 (the "Plan"), the Company hereby awards shares of the Company's common stock, par value $.01 per share ("Common Stock") to the Recipient subject to such terms, conditions, and restrictions (hereinafter, "Restricted Share Award") as set forth in the Plan, this Agreement, and the Amended and Restated Employment Agreement dated as of July 1, 1999 by and between the Company and Recipient (the "Employment Agreement"), and

WHEREAS, Recipient has agreed under the amended terms of the Employment Agreement to change his employment period to four (4) years, and to amend the amount of the severance payment Recipient may be eligible to receive upon termination of employment with the Company, and

WHEREAS, upon the vesting of Restricted Shares, Recipient is also entitled to receive a tax gross-up from the Company under the amended terms of the Employment Agreement to enable Recipient to retain as many shares of Common Stock as possible,

NOW THEREFORE, the parties hereto hereby agree as follows:


1. Award of Shares of Restricted Stock.

Pursuant to the Plan, the Committee hereby awards to the Recipient, effective as of the Grant Date, a Restricted Share Award representing the conditional receipt of 22,031 shares of Common Stock ("Restricted Shares") at no out-of-pocket cost to the Recipient subject to the terms, conditions and restrictions set forth herein. Except for defined terms set forth in Section 4 below, capitalized terms not otherwise defined in this Agreement shall be as defined in the Plan.

2. Award Restrictions.

(a) General Rules. Ownership of Restricted Shares shall not vest in the Recipient, and shall be subject to forfeiture until the conditions of Section 2(b) and (c) or Section 4 are fully satisfied. For purposes of this Agreement, the following concepts shall be defined as follows: (i) the lapse of restrictions on the Recipient's rights with respect to the Restricted Shares granted hereunder shall be referred to as "Vesting"; (ii) the period between the Grant Date and the date of Vesting shall be referred to as the "Vesting Period"; and (iii) the date Vesting occurs shall be referred to as the "Vesting Date."

(b) Vesting. An aggregate of 22,031 Restricted Shares may vest in the Recipient and vest on either a year by year basis over a five year Vesting Period or on a cumulative basis over a seven year maximum Vesting Period. The number of Restricted Shares scheduled to be vested and earned on each Vesting Date on a year by year basis provided the Performance Goals specified in Section 2(c) below are satisfied is as follows:

-2-

Restricted Shares            Vesting Date
-----------------            ------------

      3,304                 January 1, 2000
      3,305                 January 1, 2001
      4,406                 January 1, 2002
      5,508                 January 1, 2003
      5,508                 January 1, 2004

The Vesting Date for this Agreement shall be each January 1st through and including January 1, 2006. In determining the number of Restricted Shares which are earned and vested, fractional shares shall be rounded down to the nearest whole number and shall be aggregated and earned on the next Vesting Date.

(c) Performance Goals. (i) The Restricted Shares shall vest on the applicable Vesting Date on a year by year basis provided one of the following financial tests ("Financial Tests") is met for the measurement period ending on the last day of the Company's fiscal year immediately preceding such Vesting Date: (A) the Company achieves an eight percent (8%) funds from operations per common share ("FFO") increase, or (B) shareholders receive a twelve and three quarters percent (12.75%) total return (dividends, assuming reinvestment upon applicable payment date, plus stock appreciation per share of Common Stock). For purposes of this Agreement, FFO shall mean (i) net income
(loss) before minority interest of unit holders, computed in accordance with generally accepted accounting principles ("GAAP"), excluding the effect of straight lining of rents, gains (or losses) from debt restructuring, other extraordinary and significant non-recurring items, and gains (or losses) on sale of property and other property-related valuation allowances, plus real estate related depreciation and amortization, as calculated in accordance with the National Association of Real Estate Investment Trusts definition published in March 1995 after

-3-

adjustment for straight lining of rents and as applied in accordance with the accounting practices and policies of the Company in effect from time to time on a consistent basis to the entire Vesting Period, divided by (ii) the sum of (A) the diluted weighted average number of outstanding shares of Common Stock and (B) the diluted weighted average number of outstanding common limited partnership units of Mack-Cali Realty, L.P., a Delaware limited partnership of which the Company is the sole general partner, for the applicable period with such calculations being made all before the effect on FFO and diluted common shares/common limited partnership units resulting from certain non-recurring cash payments made pursuant to certain written employment agreements and from the vesting of restricted share awards and other similar plans or compensation arrangements for the applicable period.

(ii) In the event that neither of the Financial Tests above is satisfied for the fiscal year of the Company corresponding to the applicable Vesting Date ("Non-Achievement Year"), any Restricted Shares that failed to vest under the annual performance goal criteria on such Date may vest on such Date or on a subsequent Vesting Date provided the test described below is satisfied (the "Cumulative Test"). The Cumulative Test shall be applied at the end of the Non-Achievement Year or any subsequent fiscal year ("Catch-Up Year") with respect to any Non-Achievement Year provided a Financial Test was satisfied in a prior fiscal year or is satisfied in a Catch-Up Year, by applying the aggregate Financial Test percentages and the performance goal requirement on a cumulative basis beginning with the first fiscal year of the Vesting Period and ending with the Non-Achievement Year or the Catch-Up Year, as applicable. In the event the Cumulative Test is satisfied (i.e., the

-4-

aggregate increase in FFO or aggregate total return is not less than the minimum percentage required to satisfy the Financial Test after taking into account the applicable Non-Achievement Year), the Restricted Shares that failed to vest in the Non-Achievement Year shall automatically vest on the Vesting Date applicable to the Non-Achievement Year or the Catch-Up Year, as the case may be. For example, if vesting occurred in years one (1) and two (2), year three (3) is a Non-Achievement Year, and the Cumulative Test is met for the Non-Achievement Year (i.e., either FFO is not less than twenty-four (24%) percent or the aggregate return is not less than thirty-eight and one-quarter (38.25%) percent) vesting would occur on the Vesting Date applicable to the Non-Achievement Year. In the event the Cumulative Test is not met in the Non-Achievement Year, one of the Financial Tests is met in year four (4), the Cumulative Test may be used. Under this scenario, vesting in that portion of the Restricted Stock Award scheduled to vest in year three (3) will occur in year four (4) if either the aggregate FFO is not less than thirty-two percent (32%) or the aggregate total return is not less than fifty-one percent (51%) at the end of the fourth (4th) fiscal year. Rules for Application of the Cumulative Test: (a) the Cumulative Test will be applied first at the end of any Non-Achievement Year, (b) it is not necessary for any Catch-Up Year to immediately succeed a Non-Achievement Year in order for the Cumulative Test to be applicable as long as the Catch-Up Year occurs during the Vesting Period, (c) if two (2) or more Non-Achievement Years have occurred during the Vesting Period and remain non-vested, in the event that the Cumulative Test is met on a partial basis so that at least one (1) full year's vesting may occur, the Restricted Share Award granted with respect to the last Non-Achievement Year that has occurred, shall vest first and any

-5-

excess shall be credited to another Non-Achievement Year and (d) the Cumulative Test may be met on a partial basis by aggregating percentages in excess of the minimum annual requirement from more than one (1) fiscal year in the Vesting Period. For example, if vesting occurred in year one (1) and the FFO is sixteen (16%) percent, years two (2) and three (3) are Non-Achievement Years with a loss in year two (2) of two (2%) percent and year three (3) the FFO is four (4%) percent, the Restricted Shares awarded with respect to year three (3) would vest under the Cumulative Test and two (2%) percent of the remaining FFO would be available to be used in year two (2) or any other year (e.g., in the event that FFO were fourteen (14%) percent in year four (4), the Restricted Shares applicable to year two (2) would also vest. In the alternative, if FFO were six (6%) percent in year four (4), year four (4) would vest and year two (2) would remain a Non-Achievement Year). Notwithstanding any contrary provisions contained in this Section 2(c) and subject to Section 4 below, any Restricted Shares that have not been earned and vested by January 1, 2004 on a year by year basis or by January 1, 2006 pursuant to the Cumulative Test shall automatically be canceled and forfeited.

(d) Lapse of Restrictions. Upon the Vesting of Restricted Shares, the Recipient shall own the Shares free and clear of all restrictions imposed by this Agreement and the Recipient shall be free to hold or dispose of such Shares in his discretion, subject to applicable federal and state law or regulations.

(e) Prohibition Against Assignment. During the Vesting Period, the Restricted Shares may not be transferred or encumbered by the Recipient by means of sale, assignment, mortgage, transfer, exchange, pledge, or otherwise. The

-6-

levy of any execution, attachment, or similar process upon the Restricted Shares shall be null and void.

3. Stock Certificates.

(a) Certificates. Restricted Shares shall be evidenced by one or more stock certificates registered in the name of the Recipient or a nominee or nominees therefor. Prior to Vesting, the Company shall prepare and issue separate certificates for the Restricted Shares scheduled to vest in each year (the "Share Certificates"), which shall be registered in the name of the Recipient and which shall bear such restrictive legend or legends (if any) as the Company may deem necessary or desirable under any applicable law.

(b) Stock Powers. The Recipient shall execute and deliver to the designee of the Company (the "Designee") stock powers corresponding to the Share Certificates designating the Company as the transferee of an unspecified number of Shares, which stock powers may be completed by the Designee as specified herein. The Recipient and the Company each waive the requirement that the signature of the Recipient on the stock powers be guaranteed. Upon receipt of a copy of this Agreement and the stock powers, each signed by the Recipient, the Designee shall promptly notify the proper officers of the Company and the Share Certificates and stock powers shall be held by the Company in accordance with the terms of this Agreement.

(c) Effect of Vesting. Upon Vesting, the Company shall cause to be delivered to the Recipient (i) a certificate for the Shares which have vested free and clear of restrictive legends and (ii) any stock powers signed hereunder by the Recipient remaining in its possession related to the vested shares. In the event that the

-7-

Recipient dies before delivery of the certificate, such certificate shall be delivered to, and registered in the name of, the Recipient's beneficiary or estate, as the case may be.

(d) Rights of Stockholder. Except as otherwise provided in
Section 2 and this Section 3, during the Vesting Period and after the certificates for the Restricted Shares have been issued, the Recipient shall be entitled to all rights of a stockholder of the Company, including the right to vote and the right to receive dividends, with respect to the Restricted Shares subject to this Agreement. Subject to applicable withholding requirements, if any, dividends on the Restricted Shares shall be paid to the Recipient when earned and payable.

(e) Power of Designee. The Designee is hereby authorized by the Recipient to utilize the stock power delivered by the Recipient to transfer all forfeited Shares to the Company upon receipt of instructions from a duly authorized representative of the Company.

4. Termination of Employment; Change in Control.

(a) Termination Due to Disability, Death or for Good Reason; Change in Control. Unless otherwise provided in the Employment Agreement and notwithstanding any provision of the Plan to the contrary, if the Recipient terminates employment with the Company due to Disability, death, for Good Reason or a termination initiated by the Company without Cause, all Restricted Shares subject to this Agreement and held by, or on behalf of, the Recipient shall be deemed earned and vested as of the Recipient's last day of employment with the Company. In addition, unless otherwise provided in the Employment Agreement and notwithstanding any

-8-

provision of the Plan to the contrary, all Restricted Shares subject to this Agreement and held by the Recipient on the date a Change in Control occurs shall be deemed earned and vested as of such date.

(b) Termination for Any Other Reason. Unless otherwise provided in the Employment Agreement, if the Recipient's employment with the Company terminates prior to January 1, 2006 for reasons other than Disability, death, a termination initiated by the Company without Cause or for Good Reason or as a result of a Change in Control, any Restricted Shares subject to this Agreement that have not been earned and vested prior to the Recipient's termination of employment shall be immediately forfeited on the last day of the Recipient's employment with the Company.

5. Withholding.

In connection with the delivery of any stock certificates, or the making of any payment in accordance with the provisions of this Agreement, the Company shall withhold Shares or cash amounts (for fractional Shares) equal to the taxes then required by applicable federal, state and local law to be so withheld.

-9-

Plan and this Agreement to prevent dilution or enlargement of the rights granted to the Recipient.

(ii) In the event that neither of the Financial Tests above is satisfied for the fiscal year of the Company corresponding to the applicable Vesting Date ("Non-Achievement Year"), any Restricted Shares that failed to vest under the annual performance goal criteria on such Date may vest on such Date or on a subsequent Vesting Date provided the test described below is satisfied (the "Cumulative Test"). The Cumulative Test shall be applied at the end of the Non-Achievement Year or any subsequent fiscal year ("Catch-Up Year") with respect to any Non-Achievement Year provided a Financial Test was satisfied in a prior fiscal year or is satisfied in a Catch-Up Year, by applying the aggregate Financial Test percentages and the performance goal requirement on a cumulative basis beginning with the first fiscal year of the Vesting Period and ending with the Non-Achievement Year or the Catch-Up Year, as applicable. In the event the Cumulative Test is satisfied (i.e., the

-4-

aggregate increase in FFO or aggregate total return is not less than the minimum percentage required to satisfy the Financial Test after taking into account the applicable Non-Achievement Year), the Restricted Shares that failed to vest in the Non-Achievement Year shall automatically vest on the Vesting Date applicable to the Non-Achievement Year or the Catch-Up Year, as the case may be. For example, if vesting occurred in years one (1) and two (2), year three (3) is a Non-Achievement Year, and the Cumulative Test is met for the Non-Achievement Year (i.e., either FFO is not less than twenty-four (24%) percent or the aggregate return is not less than thirty-eight and one-quarter (38.25%) percent) vesting would occur on the Vesting Date applicable to the Non-Achievement Year. In the event the Cumulative Test is not met in the Non-Achievement Year, one of the Financial Tests is met in year four (4), the Cumulative Test may be used. Under this scenario, vesting in that portion of the Restricted Stock Award scheduled to vest in year three (3) will occur in year four (4) if either the aggregate FFO is not less than thirty-two percent (32%) or the aggregate total return is not less than fifty-one percent (51%) at the end of the fourth (4th) fiscal year. Rules for Application of the Cumulative Test: (a) the Cumulative Test will be applied first at the end of any Non-Achievement Year, (b) it is not necessary for any Catch-Up Year to immediately succeed a Non-Achievement Year in order for the Cumulative Test to be applicable as long as the Catch-Up Year occurs during the Vesting Period, (c) if two (2) or more Non-Achievement Years have occurred during the Vesting Period and remain non-vested, in the event that the Cumulative Test is met on a partial basis so that at least one (1) full year's vesting may occur, the Restricted Share Award granted with respect to the last Non-Achievement Year that has occurred, shall vest first and any

-5-

excess shall be credited to another Non-Achievement Year and (d) the Cumulative Test may be met on a partial basis by aggregating percentages in excess of the minimum annual requirement from more than one (1) fiscal year in the Vesting Period. For example, if vesting occurred in year one (1) and the FFO is sixteen (16%) percent, years two (2) and three (3) are Non-Achievement Years with a loss in year two (2) of two (2%) percent and year three (3) the FFO is four (4%) percent, the Restricted Shares awarded with respect to year three (3) would vest under the Cumulative Test and two (2%) percent of the remaining FFO would be available to be used in year two (2) or any other year (e.g., in the event that FFO were fourteen (14%) percent in year four (4), the Restricted Shares applicable to year two (2) would also vest. In the alternative, if FFO were six (6%) percent in year four (4), year four (4) would vest and year two (2) would remain a Non-Achievement Year). Notwithstanding any contrary provisions contained in this Section 2(c) and subject to Section 4 below, any Restricted Shares that have not been earned and vested by January 1, 2004 on a year by year basis or by January 1, 2006 pursuant to the Cumulative Test shall automatically be canceled and forfeited.

(d) Lapse of Restrictions. Upon the Vesting of Restricted Shares, the Recipient shall own the Shares free and clear of all restrictions imposed by this Agreement and the Recipient shall be free to hold or dispose of such Shares in his discretion, subject to applicable federal and state law or regulations.

(e) Prohibition Against Assignment. During the Vesting Period, the Restricted Shares may not be transferred or encumbered by the Recipient by means of sale, assignment, mortgage, transfer, exchange, pledge, or otherwise. The

-6-

levy of any execution, attachment, or similar process upon the Restricted Shares shall be null and void.

3. Stock Certificates.

(a) Certificates. Restricted Shares shall be evidenced by one or more stock certificates registered in the name of the Recipient or a nominee or nominees therefor. Prior to Vesting, the Company shall prepare and issue separate certificates for the Restricted Shares scheduled to vest in each year (the "Share Certificates"), which shall be registered in the name of the Recipient and which shall bear such restrictive legend or legends (if any) as the Company may deem necessary or desirable under any applicable law.

(b) Stock Powers. The Recipient shall execute and deliver to the designee of the Company (the "Designee") stock powers corresponding to the Share Certificates designating the Company as the transferee of an unspecified number of Shares, which stock powers may be completed by the Designee as specified herein. The Recipient and the Company each waive the requirement that the signature of the Recipient on the stock powers be guaranteed. Upon receipt of a copy of this Agreement and the stock powers, each signed by the Recipient, the Designee shall promptly notify the proper officers of the Company and the Share Certificates and stock powers shall be held by the Company in accordance with the terms of this Agreement.

(c) Effect of Vesting. Upon Vesting, the Company shall cause to be delivered to the Recipient (i) a certificate for the Shares which have vested free and clear of restrictive legends and (ii) any stock powers signed hereunder by the Recipient remaining in its possession related to the vested shares. In the event that the

-7-

Recipient dies before delivery of the certificate, such certificate shall be delivered to, and registered in the name of, the Recipient's beneficiary or estate, as the case may be.

(d) Rights of Stockholder. Except as otherwise provided in
Section 2 and this Section 3, during the Vesting Period and after the certificates for the Restricted Shares have been issued, the Recipient shall be entitled to all rights of a stockholder of the Company, including the right to vote and the right to receive dividends, with respect to the Restricted Shares subject to this Agreement. Subject to applicable withholding requirements, if any, dividends on the Restricted Shares shall be paid to the Recipient when earned and payable.

(e) Power of Designee. The Designee is hereby authorized by the Recipient to utilize the stock power delivered by the Recipient to transfer all forfeited Shares to the Company upon receipt of instructions from a duly authorized representative of the Company.

4. Termination of Employment; Change in Control.

(a) Termination Due to Disability, Death or for Good Reason; Change in Control. Unless otherwise provided in the Employment Agreement and notwithstanding any provision of the Plan to the contrary, if the Recipient terminates employment with the Company due to Disability, death, for Good Reason or a termination initiated by the Company without Cause, all Restricted Shares subject to this Agreement and held by, or on behalf of, the Recipient shall be deemed earned and vested as of the Recipient's last day of employment with the Company. In addition, unless otherwise provided in the Employment Agreement and notwithstanding any

-8-

provision of the Plan to the contrary, all Restricted Shares subject to this Agreement and held by the Recipient on the date a Change in Control occurs shall be deemed earned and vested as of such date.

(b) Termination for Any Other Reason. Unless otherwise provided in the Employment Agreement, if the Recipient's employment with the Company terminates prior to January 1, 2006 for reasons other than Disability, death, a termination initiated by the Company without Cause or for Good Reason or as a result of a Change in Control, any Restricted Shares subject to this Agreement that have not been earned and vested prior to the Recipient's termination of employment shall be immediately forfeited on the last day of the Recipient's employment with the Company.

5. Withholding.

In connection with the delivery of any stock certificates, or the making of any payment in accordance with the provisions of this Agreement, the Company shall withhold Shares or cash amounts (for fractional Shares) equal to the taxes then required by applicable federal, state and local law to be so withheld.

6. Adjustments for Capital Changes.

In the event of any change in the outstanding shares of Common Stock of the Company by reason of any stock dividend or split, recapitalization, merger, consolidation, spin-off, reorganization, combination or exchange of shares, or other similar corporate change, or other increase or decrease in such shares effected without receipt or payment of consideration by the Company, a duly authorized representative of the Company shall adjust the number of Restricted Shares granted pursuant to the

-9-

Plan and this Agreement to prevent dilution or enlargement of the rights granted to the Recipient.

7. No Right to Continued Employment.

Nothing in this Agreement shall confer on the Recipient any right to continue as an employee of the Company or in any way affect the Company's or any subsidiary's right to terminate the Recipient's employment at any time.

BARRY LEFKOWITZ


AGREEMENT EVIDENCING THE GRANT
OF A RESTRICTED SHARE AWARD PURSUANT
TO THE EMPLOYEE STOCK OPTION PLAN
OF MACK-CALI REALTY CORPORATION

AGREEMENT ("Agreement") effective as of July 1, 1999, ("Grant Date") by and between Mack-Cali Realty Corporation (the "Company") and Barry Lefkowitz ("Recipient").

WHEREAS, pursuant to the Employee Stock Option Plan of Mack-Cali Realty Corporation which was originally effective August 31, 1994 and amended and restated as of December 11, 1998 (the "Plan"), the Company hereby awards shares of the Company's common stock, par value $.01 per share ("Common Stock") to the Recipient subject to such terms, conditions, and restrictions (hereinafter, "Restricted Share Award") as set forth in the Plan, this Agreement, and the Second Amended and Restated Employment Agreement dated as of July 1, 1999 by and between the Company and Recipient (the "Employment Agreement"), and

WHEREAS, Recipient has agreed under the amended terms of the Employment Agreement to change his employment period to four (4) years, and to amend the amount of the severance payment Recipient may be eligible to receive upon termination of employment with the Company, and

WHEREAS, upon the vesting of Restricted Shares, Recipient is also entitled to receive a tax gross-up from the Company under the amended terms of the Employment Agreement to enable Recipient to retain as many shares of Common Stock as possible,

NOW THEREFORE, the parties hereto hereby agree as follows:


1. Award of Shares of Restricted Stock.

Pursuant to the Plan, the Committee hereby awards to the Recipient, effective as of the Grant Date, a Restricted Share Award representing the conditional receipt of 26,094 shares of Common Stock ("Restricted Shares") at no out-of-pocket cost to the Recipient subject to the terms, conditions and restrictions set forth herein. Except for defined terms set forth in Section 4 below, capitalized terms not otherwise defined in this Agreement shall be as defined in the Plan.

2. Award Restrictions.

(a) General Rules. Ownership of Restricted Shares shall not vest in the Recipient, and shall be subject to forfeiture until the conditions of Section 2(b) and (c) or Section 4 are fully satisfied. For purposes of this Agreement, the following concepts shall be defined as follows: (i) the lapse of restrictions on the Recipient's rights with respect to the Restricted Shares granted hereunder shall be referred to as "Vesting"; (ii) the period between the Grant Date and the date of Vesting shall be referred to as the "Vesting Period"; and (iii) the date Vesting occurs shall be referred to as the "Vesting Date."

(b) Vesting. An aggregate of 26,094 Restricted Shares may vest in the Recipient and vest on either a year by year basis over a five year Vesting Period or on a cumulative basis over a seven year maximum Vesting Period. The number of Restricted Shares scheduled to be vested and earned on each Vesting Date on a year by year basis provided the Performance Goals specified in Section 2(c) below are satisfied is as follows:

-2-

Restricted Shares             Vesting Date
-----------------             ------------

      3,914                 January 1, 2000
      3,914                 January 1, 2001
      5,218                 January 1, 2002
      6,523                 January 1, 2003
      6,525                 January 1, 2004

The Vesting Date for this Agreement shall be each January 1st through and including January 1, 2006. In determining the number of Restricted Shares which are earned and vested, fractional shares shall be rounded down to the nearest whole number and shall be aggregated and earned on the next Vesting Date.

(c) Performance Goals. (i) The Restricted Shares shall vest on the applicable Vesting Date on a year by year basis provided one of the following financial tests ("Financial Tests") is met for the measurement period ending on the last day of the Company's fiscal year immediately preceding such Vesting Date: (A) the Company achieves an eight percent (8%) funds from operations per common share ("FFO") increase, or (B) shareholders receive a twelve and three quarters percent (12.75%) total return (dividends, assuming reinvestment upon applicable payment date, plus stock appreciation per share of Common Stock). For purposes of this Agreement, FFO shall mean (i) net income
(loss) before minority interest of unit holders, computed in accordance with generally accepted accounting principles ("GAAP"), excluding the effect of straight lining of rents, gains (or losses) from debt restructuring, other extraordinary and significant non-recurring items, and gains (or losses) on sale of property and other property-related valuation allowances, plus real estate related depreciation and amortization, as calculated in accordance with the National Association of Real Estate Investment Trusts definition published in March 1995 after

-3-

adjustment for straight lining of rents and as applied in accordance with the accounting practices and policies of the Company in effect from time to time on a consistent basis to the entire Vesting Period, divided by (ii) the sum of (A) the diluted weighted average number of outstanding shares of Common Stock and (B) the diluted weighted average number of outstanding common limited partnership units of Mack-Cali Realty, L.P., a Delaware limited partnership of which the Company is the sole general partner, for the applicable period with such calculations being made all before the effect on FFO and diluted common shares/common limited partnership units resulting from certain non-recurring cash payments made pursuant to certain written employment agreements and from the vesting of restricted share awards and other similar plans or compensation arrangements for the applicable period.

(ii) In the event that neither of the Financial Tests above is satisfied for the fiscal year of the Company corresponding to the applicable Vesting Date ("Non-Achievement Year"), any Restricted Shares that failed to vest under the annual performance goal criteria on such Date may vest on such Date or on a subsequent Vesting Date provided the test described below is satisfied (the "Cumulative Test"). The Cumulative Test shall be applied at the end of the Non-Achievement Year or any subsequent fiscal year ("Catch-Up Year") with respect to any Non-Achievement Year provided a Financial Test was satisfied in a prior fiscal year or is satisfied in a Catch-Up Year, by applying the aggregate Financial Test percentages and the performance goal requirement on a cumulative basis beginning with the first fiscal year of the Vesting Period and ending with the Non-Achievement Year or the Catch-Up Year, as applicable. In the event the Cumulative Test is satisfied (i.e., the

-4-

aggregate increase in FFO or aggregate total return is not less than the minimum percentage required to satisfy the Financial Test after taking into account the applicable Non-Achievement Year), the Restricted Shares that failed to vest in the Non-Achievement Year shall automatically vest on the Vesting Date applicable to the Non-Achievement Year or the Catch-Up Year, as the case may be. For example, if vesting occurred in years one (1) and two (2), year three (3) is a Non-Achievement Year, and the Cumulative Test is met for the Non-Achievement Year (i.e., either FFO is not less than twenty-four (24%) percent or the aggregate return is not less than thirty-eight and one-quarter (38.25%) percent) vesting would occur on the Vesting Date applicable to the Non-Achievement Year. In the event the Cumulative Test is not met in the Non-Achievement Year, one of the Financial Tests is met in year four (4), the Cumulative Test may be used. Under this scenario, vesting in that portion of the Restricted Stock Award scheduled to vest in year three (3) will occur in year four (4) if either the aggregate FFO is not less than thirty-two percent (32%) or the aggregate total return is not less than fifty-one percent (51%) at the end of the fourth (4th) fiscal year. Rules for Application of the Cumulative Test: (a) the Cumulative Test will be applied first at the end of any Non-Achievement Year, (b) it is not necessary for any Catch-Up Year to immediately succeed a Non-Achievement Year in order for the Cumulative Test to be applicable as long as the Catch-Up Year occurs during the Vesting Period, (c) if two (2) or more Non-Achievement Years have occurred during the Vesting Period and remain non-vested, in the event that the Cumulative Test is met on a partial basis so that at least one (1) full year's vesting may occur, the Restricted Share Award granted with respect to the last Non-Achievement Year that has occurred, shall vest first and any

-5-

excess shall be credited to another Non-Achievement Year and (d) the Cumulative Test may be met on a partial basis by aggregating percentages in excess of the minimum annual requirement from more than one (1) fiscal year in the Vesting Period. For example, if vesting occurred in year one (1) and the FFO is sixteen (16%) percent, years two (2) and three (3) are Non-Achievement Years with a loss in year two (2) of two (2%) percent and year three (3) the FFO is four (4%) percent, the Restricted Shares awarded with respect to year three (3) would vest under the Cumulative Test and two (2%) percent of the remaining FFO would be available to be used in year two (2) or any other year (e.g., in the event that FFO were fourteen (14%) percent in year four (4), the Restricted Shares applicable to year two (2) would also vest. In the alternative, if FFO were six (6%) percent in year four (4), year four (4) would vest and year two (2) would remain a Non-Achievement Year). Notwithstanding any contrary provisions contained in this Section 2(c) and subject to Section 4 below, any Restricted Shares that have not been earned and vested by January 1, 2004 on a year by year basis or by January 1, 2006 pursuant to the Cumulative Test shall automatically be canceled and forfeited.

(d) Lapse of Restrictions. Upon the Vesting of Restricted Shares, the Recipient shall own the Shares free and clear of all restrictions imposed by this Agreement and the Recipient shall be free to hold or dispose of such Shares in his discretion, subject to applicable federal and state law or regulations.

(e) Prohibition Against Assignment. During the Vesting Period, the Restricted Shares may not be transferred or encumbered by the Recipient by means of sale, assignment, mortgage, transfer, exchange, pledge, or otherwise. The

-6-

levy of any execution, attachment, or similar process upon the Restricted Shares shall be null and void.

3. Stock Certificates.

Upon Vesting, the Company shall cause to be delivered to the Recipient (i) a certificate for the Shares which have vested free and clear of restrictive legends and (ii) any stock powers signed hereunder by the Recipient remaining in its possession related to the vested shares. In the event that the

-7-

Recipient dies before delivery of the certificate, such certificate shall be delivered to, and registered in the name of, the Recipient's beneficiary or estate, as the case may be.

Section 2 and this Section 3, during the Vesting Period and after the certificates for the Restricted Shares have been issued, the Recipient shall be entitled to all rights of a stockholder of the Company, including the right to vote and the right to receive dividends, with respect to the Restricted Shares subject to this Agreement. Subject to applicable withholding requirements, if any, dividends on the Restricted Shares shall be paid to the Recipient when earned and payable.

(e) Power of Designee. The Designee is hereby authorized by the Recipient to utilize the stock power delivered by the Recipient to transfer all forfeited Shares to the Company upon receipt of instructions from a duly authorized representative of the Company.

4. Termination of Employment; Change in Control.

Unless otherwise provided in the Employment Agreement and notwithstanding any provision of the Plan to the contrary, if the Recipient terminates employment with the Company due to Disability, death, for Good Reason or a termination initiated by the Company without Cause, all Restricted Shares subject to this Agreement and held by, or on behalf of, the Recipient shall be deemed earned and vested as of the Recipient's last day of employment with the Company. In addition, unless otherwise provided in the Employment Agreement and notwithstanding any

-8-

provision of the Plan to the contrary, all Restricted Shares subject to this Agreement and held by the Recipient on the date a Change in Control occurs shall be deemed earned and vested as of such date.

(b) Termination for Any Other Reason. Unless otherwise provided in the Employment Agreement, if the Recipient's employment with the Company terminates prior to January 1, 2006 for reasons other than Disability, death, a termination initiated by the Company without Cause or for Good Reason or as a result of a Change in Control, any Restricted Shares subject to this Agreement that have not been earned and vested prior to the Recipient's termination of employment shall be immediately forfeited on the last day of the Recipient's employment with the Company.

For purposes of this Agreement, FFO shall mean (i) net income
(loss) before minority interest of unit holders, computed in accordance with generally accepted accounting principles ("GAAP"), excluding the effect of straight lining of rents, gains (or losses) from debt restructuring, other extraordinary and significant non-recurring items, and gains (or losses) on sale of property and other property-related valuation allowances, plus real estate related depreciation and amortization, as calculated in accordance with the National Association of Real Estate Investment Trusts definition published in March 1995 after

-3-

adjustment for straight lining of rents and as applied in accordance with the accounting practices and policies of the Company in effect from time to time on a consistent basis to the entire Vesting Period, divided by (ii) the sum of (A) the diluted weighted average number of outstanding shares of Common Stock and (B) the diluted weighted average number of outstanding common limited partnership units of Mack-Cali Realty, L.P., a Delaware limited partnership of which the Company is the sole general partner, for the applicable period with such calculations being made all before the effect on FFO and diluted common shares/common limited partnership units resulting from certain non-recurring cash payments made pursuant to certain written employment agreements and from the vesting of restricted share awards and other similar plans or compensation arrangements for the applicable period.

(ii) In the event that neither of the Financial Tests above is satisfied for the fiscal year of the Company corresponding to the applicable Vesting Date ("Non-Achievement Year"), any Restricted Shares that failed to vest under the annual performance goal criteria on such Date may vest on such Date or on a subsequent Vesting Date provided the test described below is satisfied (the "Cumulative Test"). The Cumulative Test shall be applied at the end of the Non-Achievement Year or any subsequent fiscal year ("Catch-Up Year") with respect to any Non-Achievement Year provided a Financial Test was satisfied in a prior fiscal year or is satisfied in a Catch-Up Year, by applying the aggregate Financial Test percentages and the performance goal requirement on a cumulative basis beginning with the first fiscal year of the Vesting Period and ending with the Non-Achievement Year or the Catch-Up Year, as applicable. In the event the Cumulative Test is satisfied (i.e., the

-4-

aggregate increase in FFO or aggregate total return is not less than the minimum percentage required to satisfy the Financial Test after taking into account the applicable Non-Achievement Year), the Restricted Shares that failed to vest in the Non-Achievement Year shall automatically vest on the Vesting Date applicable to the Non-Achievement Year or the Catch-Up Year, as the case may be. For example, if vesting occurred in years one (1) and two (2), year three (3) is a Non-Achievement Year, and the Cumulative Test is met for the Non-Achievement Year (i.e., either FFO is not less than twenty-four (24%) percent or the aggregate return is not less than thirty-eight and one-quarter (38.25%) percent) vesting would occur on the Vesting Date applicable to the Non-Achievement Year. In the event the Cumulative Test is not met in the Non-Achievement Year, one of the Financial Tests is met in year four (4), the Cumulative Test may be used. Under this scenario, vesting in that portion of the Restricted Stock Award scheduled to vest in year three (3) will occur in year four (4) if either the aggregate FFO is not less than thirty-two percent (32%) or the aggregate total return is not less than fifty-one percent (51%) at the end of the fourth (4th) fiscal year. Rules for Application of the Cumulative Test: (a) the Cumulative Test will be applied first at the end of any Non-Achievement Year, (b) it is not necessary for any Catch-Up Year to immediately succeed a Non-Achievement Year in order for the Cumulative Test to be applicable as long as the Catch-Up Year occurs during the Vesting Period, (c) if two (2) or more Non-Achievement Years have occurred during the Vesting Period and remain non-vested, in the event that the Cumulative Test is met on a partial basis so that at least one (1) full year's vesting may occur, the Restricted Share Award granted with respect to the last Non-Achievement Year that has occurred, shall vest first and any

-5-

excess shall be credited to another Non-Achievement Year and (d) the Cumulative Test may be met on a partial basis by aggregating percentages in excess of the minimum annual requirement from more than one (1) fiscal year in the Vesting Period. For example, if vesting occurred in year one (1) and the FFO is sixteen (16%) percent, years two (2) and three (3) are Non-Achievement Years with a loss in year two (2) of two (2%) percent and year three (3) the FFO is four (4%) percent, the Restricted Shares awarded with respect to year three (3) would vest under the Cumulative Test and two (2%) percent of the remaining FFO would be available to be used in year two (2) or any other year (e.g., in the event that FFO were fourteen (14%) percent in year four (4), the Restricted Shares applicable to year two (2) would also vest. In the alternative, if FFO were six (6%) percent in year four (4), year four (4) would vest and year two (2) would remain a Non-Achievement Year). Notwithstanding any contrary provisions contained in this Section 2(c) and subject to Section 4 below, any Restricted Shares that have not been earned and vested by January 1, 2004 on a year by year basis or by January 1, 2006 pursuant to the Cumulative Test shall automatically be canceled and forfeited.

(d) Lapse of Restrictions. Upon the Vesting of Restricted Shares, the Recipient shall own the Shares free and clear of all restrictions imposed by this Agreement and the Recipient shall be free to hold or dispose of such Shares in his discretion, subject to applicable federal and state law or regulations.

(e) Prohibition Against Assignment. During the Vesting Period, the Restricted Shares may not be transferred or encumbered by the Recipient by means of sale, assignment, mortgage, transfer, exchange, pledge, or otherwise. The

-6-

levy of any execution, attachment, or similar process upon the Restricted Shares shall be null and void.

3. Stock Certificates.

(a) Certificates. Restricted Shares shall be evidenced by one or more stock certificates registered in the name of the Recipient or a nominee or nominees therefor. Prior to Vesting, the Company shall prepare and issue separate certificates for the Restricted Shares scheduled to vest in each year (the "Share Certificates"), which shall be registered in the name of the Recipient and which shall bear such restrictive legend or legends (if any) as the Company may deem necessary or desirable under any applicable law.

(b) Stock Powers. The Recipient shall execute and deliver to the designee of the Company (the "Designee") stock powers corresponding to the Share Certificates designating the Company as the transferee of an unspecified number of Shares, which stock powers may be completed by the Designee as specified herein. The Recipient and the Company each waive the requirement that the signature of the Recipient on the stock powers be guaranteed. Upon receipt of a copy of this Agreement and the stock powers, each signed by the Recipient, the Designee shall promptly notify the proper officers of the Company and the Share Certificates and stock powers shall be held by the Company in accordance with the terms of this Agreement.

(c) Effect of Vesting. Upon Vesting, the Company shall cause to be delivered to the Recipient (i) a certificate for the Shares which have vested free and clear of restrictive legends and (ii) any stock powers signed hereunder by the Recipient remaining in its possession related to the vested shares. In the event that the

-7-

Recipient dies before delivery of the certificate, such certificate shall be delivered to, and registered in the name of, the Recipient's beneficiary or estate, as the case may be.

(d) Rights of Stockholder. Except as otherwise provided in
Section 2 and this Section 3, during the Vesting Period and after the certificates for the Restricted Shares have been issued, the Recipient shall be entitled to all rights of a stockholder of the Company, including the right to vote and the right to receive dividends, with respect to the Restricted Shares subject to this Agreement. Subject to applicable withholding requirements, if any, dividends on the Restricted Shares shall be paid to the Recipient when earned and payable.

(e) Power of Designee. The Designee is hereby authorized by the Recipient to utilize the stock power delivered by the Recipient to transfer all forfeited Shares to the Company upon receipt of instructions from a duly authorized representative of the Company.

4. Termination of Employment; Change in Control.

(a) Termination Due to Disability, Death or for Good Reason; Change in Control. Unless otherwise provided in the Employment Agreement and notwithstanding any provision of the Plan to the contrary, if the Recipient terminates employment with the Company due to Disability, death, for Good Reason or a termination initiated by the Company without Cause, all Restricted Shares subject to this Agreement and held by, or on behalf of, the Recipient shall be deemed earned and vested as of the Recipient's last day of employment with the Company. In addition, unless otherwise provided in the Employment Agreement and notwithstanding any

-8-

provision of the Plan to the contrary, all Restricted Shares subject to this Agreement and held by the Recipient on the date a Change in Control occurs shall be deemed earned and vested as of such date.

(b) Termination for Any Other Reason. Unless otherwise provided in the Employment Agreement, if the Recipient's employment with the Company terminates prior to January 1, 2006 for reasons other than Disability, death, a termination initiated by the Company without Cause or for Good Reason or as a result of a Change in Control, any Restricted Shares subject to this Agreement that have not been earned and vested prior to the Recipient's termination of employment shall be immediately forfeited on the last day of the Recipient's employment with the Company.

5. Withholding.

In connection with the delivery of any stock certificates, or the making of any payment in accordance with the provisions of this Agreement, the Company shall withhold Shares or cash amounts (for fractional Shares) equal to the taxes then required by applicable federal, state and local law to be so withheld.

6. Adjustments for Capital Changes.

In the event of any change in the outstanding shares of Common Stock of the Company by reason of any stock dividend or split, recapitalization, merger, consolidation, spin-off, reorganization, combination or exchange of shares, or other similar corporate change, or other increase or decrease in such shares effected without receipt or payment of consideration by the Company, a duly authorized representative of the Company shall adjust the number of Restricted Shares granted pursuant to the

-9-

Plan and this Agreement to prevent dilution or enlargement of the rights granted to the Recipient.

7. No Right to Continued Employment.

Nothing in this Agreement shall confer on the Recipient any right to continue as an employee of the Company or in any way affect the Company's or any subsidiary's right to terminate the Recipient's employment at any time.

Buyer will not be obligated to provide copies of any documents prepared by Buyer, including business plans or projections relating to the transaction contemplated by this Agreement. Failure on the part of Buyer to give notice of dissatisfaction with respect to any of the matters stated above within the Due Diligence Period as above provided shall constitute a waiver of the right to terminate this Agreement pursuant to this Section 2.4.

Section 2.5 Lease Of Additional Space; Additional Consideration.

(a) Seller shall have the right to lease Additional Space in the Building consisting of either (i) one-half (1/2) of the net rentable square feet on the main floor (that portion located on the west side of the Building) at a full-service rental rate of $32.00 per rentable square foot (i.e., having a base rent of $32.00 per rentable square foot and charging additional rent for the tenant's pro rata share of operating costs that exceed the cost of operating expenses in the Base Year as described in the Lease), or (ii) one-half (1/2) of the net rentable square feet on the fourth floor at a full-service rental rate of $32.00 per rentable square foot, as Buyer may elect, upon all of the terms, covenants and conditions contained in the Lease. Seller shall exercise its election by duly executing and delivering to Buyer the election to lease Additional Space that Buyer shall select pursuant to the Lease. Seller's failure to (i) elect to lease Additional Space, and (ii) commence payment of rent therefor as provided in the Lease, shall constitute an irrevocable election to relinquish the right to lease the Additional Space.

-12-

(b) Within ten (10) Days after receipt of Seller's election to lease Additional Space, Buyer shall duly execute and return to Seller notice of the specific Additional Space to which the election shall apply as specified above at Buyer's election. Buyer's failure to notify Seller of the Additional Space to which the election shall apply within ten (10) Days after Seller's delivery of the notice of election to lease Additional Space shall constitute a waiver of the right so to elect, but it shall not in any way diminish or reduce Seller's right to lease the Additional Space and select the Premises to which it shall apply, given Buyer's failure to do so.

(c) Notwithstanding the foregoing Sections 2.5(a) and 2.5(b), if, before the exercise by Seller of its option to lease Additional Space as set forth in Section 2.5(a), Buyer (i) has leased either of the spaces as to which Seller has an option, and (ii) has received a letter of intent or other written proposal to lease the other space as to which Seller has an option, which said proposal Buyer desires to accept, then Buyer shall give written notice to Seller that Buyer has received such letter of intent or proposal, and Seller shall have twenty-five (25) Days within which to exercise its option to lease Additional Space under this Section 2.5, applying only to the space that Buyer has not yet leased to a third party. If Seller fails to exercise its option within such twenty-five (25) Day period, Seller's option under this Section 2.5 shall terminate.

(d) If Seller elects to lease Additional Space and Seller's option to do so has not terminated under Section 2.5(c), then Buyer shall pay to Seller the Additional Consideration not later than five (5) Business Days after Buyer receives the first payment of rent for the Additional Space.

(e) The rights and obligations of the parties under this Section 2.5 shall survive the Closing.

Within fifteen (15) Days after the Effective Date, Buyer shall advise Seller in writing of any title defects, liens, encumbrances, other objections to title or items shown on the Survey (as defined below) other than the Permitted Exceptions. Buyer's failure to give such notice shall constitute an irrevocable waiver of all such matters disclosed by the Title Report and Survey. Buyer's rights under this Article 4 are in addition to Buyer's rights under Section 2.4. For purposes hereof, the "Survey" shall be the ALTA/ACSM survey of the Property obtained by Buyer at its cost and expense.

Section 4.2 Seller's Right To Extend Closing.

If Buyer objects properly and in a timely manner to any title or Survey matter under Section 4.1 of this Agreement, then Seller shall, at its option, be entitled to an adjournment of the Closing, if necessary, for a period not to exceed thirty (30) Days after the scheduled Closing Date, to enable Seller to attempt to remove any claimed title defect, lien, encumbrance or objection that Seller is willing to remove or is obligated to remove pursuant to Section 4.3 of this Agreement.

If Buyer notifies Seller of any title defect, lien, encumbrance or objection pursuant to Section 4.1 of this Agreement, Seller shall not be required or obligated to (i) commence any

litigation or (ii) incur any costs or expenses to cure or remove any defect, lien, encumbrance or objection, except that Seller shall be obligated to (x) cure, remove or provide for the satisfaction of any defect, lien, encumbrance or objection that arises from Seller's actions after the Effective Date of this Agreement, (y) remove any mortgage, deed of trust, tax, mechanic's, materialman's or similar lien (other than the lien of non-delinquent real property taxes) created by, through or under Seller and existing at any time prior to the Closing Date, and (z) remove any liens created by, through or under third parties to the extent that the cost of such removal does not exceed two hundred thousand dollars ($200,000). Notwithstanding anything to the contrary herein contained, Seller has disclosed to Buyer that the Survey will show the possibility of immaterial gaps and immaterial overlaps due to minor discrepancies between the record and survey descriptions. Any such gaps and overlaps due to such discrepancies shall not constitute ground for objection to title by Buyer so long as Title Company is willing to insure title to the Property in accordance with the requirements hereof without exception for any such matters, with Seller's share of the cost of such title insurance not to exceed fifty cents ($0.50) per one thousand dollars ($1,000) of coverage.

I.6 Earnest Money.

(a) Simultaneously with the execution and delivery of this Agreement, Purchaser is depositing with Commercial Settlements, Inc. (the "Escrow Agent"), having its office at 1413 K Street, N.W., 12th Floor, Washington, D.C. 20005 Attention: Stuart S. Levin, the sum of One Million and No/100 Dollars ($1,000,000.00) (the "Earnest Money") in good funds, either by certified bank or cashier's check or by federal wire transfer. Purchaser shall provide Purchaser's federal tax identification number to Escrow Agent concurrently with the making of such deposit. The Escrow Agent shall hold the Earnest Money in an interest-bearing account in accordance with the terms and conditions of this Agreement. All interest accruing on such sum shall become a part of the Earnest Money and shall be distributed as Earnest Money in accordance with the terms of this Agreement.

(b) In the event of termination of this Agreement prior to Closing, the Escrow Agent shall disburse the Earnest Money in accordance with the provisions of this Agreement governing such termination. Upon receipt of a party's written demand for the Earnest Money, the Escrow Agent shall promptly mail a copy of such demand to the other party, who shall then have five (5) days to dispute the disbursement by sending written notice of such objection to the Escrow Agent. In the event of any dispute between Seller and Purchaser regarding the disbursement

3

of the Earnest Money, or in the event the Escrow Agent shall receive conflicting demands or instructions with respect thereto, the Escrow Agent shall withhold disbursement of the Earnest Money until such dispute is resolved. Alternatively, the Escrow Agent shall be entitled to deposit the Earnest Money into a court of general jurisdiction in the District of Columbia or the United States District Court for the District of Columbia, and to interplead Seller and Purchaser in connection therewith. The costs of any such action for interpleader shall be paid by whichever of Seller or Purchaser is the losing party.

I.7 Independent Contract Consideration. In addition to the Earnest Money, Purchaser shall, concurrently with its execution hereof, deliver to Seller a check in the amount of ONE HUNDRED AND NO/100ths DOLLARS ($100.00), which amount Seller and Purchaser agree has been bargained for as consideration for Seller's execution and delivery of this Agreement and Purchaser's right to inspect the Property pursuant to Article III. Such sum is in addition to and independent of any other consideration or payment provided for in this Agreement and is nonrefundable in all events.

65535RT65535CLE IITITLE AND SURVEY

II.1 Title Examination; Commitment for Title Insurance. Seller has obtained and delivered to Purchaser at no cost to Purchaser and the surveyor preparing the Survey, from Commonwealth Land Title Insurance Company (the "Title Company"), a current ALTA title insurance commitment No. 99-1135 (the "Title Commitment") covering the Property and a copy of each document referenced in the Title Commitment as an exception to title to the Property. Purchaser shall have until June 21, 1999 (the "Title Exam Deadline"), to review the Title Commitment (regardless if such date occurs prior to the Effective Date). At Closing, at Purchaser's expense, Purchaser shall obtain from the Title Company an Owner's Policy of Title Insurance in the full amount of the Purchase Price pursuant to
Section 2.4 hereof.

II.2 Survey. Seller has obtained and delivered to Purchaser and the Title Company at no cost to Purchaser a current ALTA survey of the Property prepared by Bernard F. Locraft Civil Engineers (the "Survey") reflecting the total area of the Property, the location of all improvements, recorded easements and encroachments, if any, located thereon and other matters of record with respect thereto. Purchaser shall pay any costs associated with any changes to the Survey (or certifications thereon or updates thereto) requested by Purchaser.

II.3 Title Objections; Cure of Title Objections.

(a) Purchaser shall have until the Title Exam Deadline to notify Seller, in writing, of such objections as Purchaser may have to anything contained in the Title

4

Commitment or the Survey. (Seller shall use good faith efforts, but without any cost or liability to Seller, to remove or cure title objections raised by Purchaser as to matters set forth on the Title Commitment.) Any item contained in the Title Commitment or any matter shown on the Survey to which Purchaser does not object prior to the Title Exam Deadline shall be deemed a Permitted Exception. In the event Purchaser shall notify Seller of objections to title or to matters shown on the Survey prior to the Title Exam Deadline, Seller shall have the right, but not the obligation, to cure such objections; provided, however, that notwithstanding anything to the contrary contained in this Agreement, Seller shall be obligated, at its sole cost and expense, to take such actions as may be necessary to cause the Title Company to delete as an exception, by payment or other appropriate measure of satisfaction, any mechanic's lien, IRS payment lien, judgment lien or deed of trust or other financing lien created prior to Closing by any action or inaction of Seller, which liens shall be deemed to be excluded from the term "Permitted Exceptions."

(b) Within ten (10) days after receipt of Purchaser's notice of objections, Seller shall notify Purchaser in writing whether Seller elects to attempt to cure such objections. If Seller fails to give Purchaser such notice of election, then Seller shall be deemed to have elected not to attempt to cure the matter. If Seller elects to attempt to cure, and provided that Purchaser shall not have terminated this Agreement in accordance with Section 3.2 hereof, Seller shall have until the date of Closing to attempt to remove, satisfy or cure the same and for this purpose Seller shall be entitled to a reasonable adjournment of the Closing if additional time is required, but in no event shall the adjournment exceed thirty (30) days after the date for Closing set forth in Section 4.1 hereof. If Seller elects not to cure any objections specified in Purchaser's notice, or if Seller is unable to effect a cure prior to the Closing (or any date to which the Closing has been adjourned), Purchaser shall have the following options: (i) to accept a conveyance of the Property subject to the Permitted Exceptions, specifically including any matter objected to by Purchaser which Seller is unwilling or unable to cure, and without reduction of the Purchase Price; or (ii) to terminate this Agreement by sending written notice thereof to Seller, and upon delivery of such notice of termination, this Agreement shall terminate and the Earnest Money shall be returned to Purchaser, and thereafter neither party hereto shall have any further rights, obligations or liabilities hereunder except to the extent that any right, obligation or liability set forth herein expressly survives termination of this Agreement. If Seller notifies Purchaser that Seller does not intend to attempt to cure any title objection or objections, or if, having commenced attempts to cure any objection or objections, Seller later notifies Purchaser that Seller will be unable to effect a cure thereof, Purchaser shall, within ten (10) days after such notice has been given, notify Seller in writing whether Purchaser shall elect to accept the

5

conveyance under clause (i) or to terminate this Agreement under clause (ii). In the event Purchaser does not so timely notify Seller within such 10-day period, then Purchaser shall be deemed to have elected to terminate this Agreement under clause (ii).

II.4 Conveyance of Title. As a condition of Closing, Seller shall convey and transfer to Purchaser, and the Title Company shall insure by a standard 1970-B ALTA Owner's Policy of Title Insurance (or its equivalent) (the "Title Policy"), at Purchaser's sole cost, good and marketable title to the Property (as defined in such Title Policy), in the full amount of the Purchase Price (at such rates as Purchaser may negotiate with the Title Company), in the name of Purchaser or Purchaser's designee, and with such endorsements as Purchaser shall reasonably require and which the Title Company shall agree to issue to Purchaser prior to the Title Exam Deadline (all of which shall be at Purchaser's sole expense). Notwithstanding anything contained herein to the contrary, the Property shall be conveyed subject only to the following matters, which shall be deemed to be Permitted Exceptions:

(1) the rights of Tenants, as tenants only, under the Leases and any new Leases entered into between the Effective Date and Closing and, where required, approved by Purchaser in accordance with the terms of this Agreement;

(2) the lien of all ad valorem real estate taxes and assessments not yet due and payable as of the date of Closing, subject to adjustment as herein provided;

(3) local, state and federal laws, ordinances or governmental regulations, including but not limited to, building and zoning laws, ordinances and regulations, now or hereafter in effect relating to the Property; and

(4) items as shown on the Title Commitment or the Survey which are not objected to by Purchaser or which are waived by Purchaser in accordance with Sections 2.3 or 2.5 hereof.

II.5 Pre-Closing "Gap" Title Defects. Whether or not Purchaser shall have furnished to Seller any notice of title objections pursuant to the foregoing provisions of this Section 2, Purchaser may, at or prior to Closing, notify Seller in writing of any objections to title first raised by the Title Company or the Surveyor between (a) the date which is the earlier of (i) the effective date of Purchaser's Title Commitment referred to above or (ii) the expiration of the Inspection Period, and (b) the date on which the transaction contemplated herein is scheduled to close. With respect to any objections to title set forth in such notice, Seller shall have the same option to cure and Purchaser shall have the same option to accept title subject to such matters or to terminate this Agreement as those which apply to any notice of objections made by Purchaser before the expiration of the Inspection Period. If Seller elects to attempt to cure any such matters, the date for Closing shall be automatically extended by a reasonable additional time to effect such a cure, but in no event shall the extension exceed thirty (30) days after the date for Closing set forth in

6

Section 4.1 hereof.

65535RT65535CLE IIIINSPECTION PERIOD

III.1 Right of Inspection.

(a) During the period beginning upon the Effective Date and ending at 5:00 p.m. Eastern time on June 30, 1999, with time being of the essence thereto (such period hereinafter referred to as the "Inspection Period"), Purchaser shall have the right to make a physical inspection of the Property and to examine at such place or places at the Property, in the offices of the property manager or elsewhere as the same may be located, any operating files maintained by Seller or its property manager in connection with the leasing, maintenance and/or management of the Property, including, without limitation, the Leases, lease files, Operating Agreements, insurance policies, bills, invoices, receipts and other general records relating to the income and expenses of the Property, correspondence, surveys, plans and specifications, warranties for services and materials provided to the Property, environmental audits and similar materials, but excluding materials not directly related to the leasing, maintenance and/or management of the Property such as, without limitation, Seller's internal memoranda, financial projections, budgets, appraisals, accounting and tax records and similar proprietary, elective or confidential information. Purchaser understands and agrees that any on-site inspections of the Property shall be conducted upon at least twenty-four (24) hours' prior written notice to Seller and in the presence of Seller or its representative. Such physical inspection shall not unreasonably interfere with the use of the Property by Seller or its tenants nor shall Purchaser's inspection damage the Property in any respect. Such physical inspection shall not be invasive in any respect (unless Purchaser obtains Seller's prior written consent, which consent shall not be unreasonably withheld or delayed), and in any event shall be conducted in accordance with standards customarily employed in the industry and in compliance with all governmental laws, rules and regulations. Seller acknowledges that Purchaser may request the right to conduct certain customary invasive tests with respect to testing the environmental condition of the Property. During the Inspection Period and at all times prior to Closing, Purchaser, its agents and contractors, shall have reasonable access to the Property and other information pertaining thereto in the possession or within the control of Seller or its property manager for the purpose of performing such studies, tests, borings, investigations and inspections as Purchaser shall deem necessary or desirable (it being understood that physical testing shall require Seller's prior written approval, which approval shall not be unreasonably withheld or delayed). Following each entry by Purchaser with respect to inspections and/or tests on the Property, Purchaser shall restore the Property to a condition which is as near to its original condition as existed prior to any such inspections and/or tests. Except as

7

specifically set forth in Section 5.3, Purchaser's right of inspection and the exercise of such right shall not constitute a waiver by Purchaser of a breach of any representation, warranty, covenant or agreement of Seller which might, or should, have been disclosed by such inspection.

(b) Seller shall cooperate with Purchaser in Purchaser's due diligence but Seller shall not be obligated to incur any liability or expense in connection therewith. Purchaser shall not contact any tenants of the Property or any governmental or quasi-governmental authorities without obtaining Seller's prior written consent (which consent shall not be unreasonably withheld or delayed), and Purchaser and its agents shall not disrupt Seller's or Seller's tenants' activities on the Property. Seller acknowledges that Purchaser shall require contact with such parties prior to the expiration of the Inspection Period in order to complete its due diligence. Purchaser agrees to indemnify against and hold Seller harmless from any claim for liabilities, costs, expenses (including reasonable attorneys' fees actually incurred by Seller or Seller's agents or management company), damages or injuries to the extent arising out of, or resulting from any acts or omissions of Purchaser or Purchaser's agents in connection with the inspection of the Property by Purchaser or its agents (but the foregoing indemnity shall not apply to any claims arising out of, or resulting from, the discovery by Purchaser of any existing environmental conditions or matters). Notwithstanding anything to the contrary in this Agreement, Purchaser's obligation to indemnify Seller and hold Seller harmless shall survive Closing or any termination of this Agreement. All inspections shall occur at reasonable times agreed upon by Seller and Purchaser.

III.2 Right of Termination. Seller agrees that in the event Purchaser determines (such determination to be made in Purchaser's sole discretion) that the Property is not suitable for its purposes, or for any reason or for no reason, Purchaser shall have the right to terminate this Agreement by giving written notice thereof to Seller prior to the expiration of the Inspection Period. If Purchaser or Purchaser's attorneys shall give or fail to give such notice of termination prior to expiration of the Inspection Period, then this Agreement shall terminate and the Earnest Money shall be returned to Purchaser. Time is of the essence with respect to the provisions of this Section 3.2.

65535RT65535CLE IVCLOSING

IV.1 Time and Place. The consummation of the transaction contemplated hereby ("Closing") shall be held at the offices of Rudnick & Wolfe, 1201 New York Avenue, N.W., Penthouse, Washington, D.C., at 10:30 a.m. on July 15, 1999, or such earlier date to which Seller and Purchaser may agree. At Closing, Seller and Purchaser shall perform the obligations set forth in, respectively, Section 4.2 and Section 4.3, the performance of which obligations shall be concurrent conditions. Notwithstanding anything in this Section 4.1 to the contrary, the parties agree to use commercially reasonable efforts to pre-close the transaction contemplated hereby

8

(i.e., sign documents into escrow) on the business day immediately preceding the then-scheduled date of Closing.

IV.2 Seller's Obligations at Closing. At Closing, Seller shall:

(1) deliver to Purchaser a duly executed special warranty deed with a covenant of further assurances in recordable form (the "Deed"), conveying the Land and Improvements, subject only to the Permitted Exceptions;

(2) deliver to Purchaser a duly executed bill of sale conveying the Personal Property without warranty of title or use and without warranty, expressed or implied, as to merchantability and fitness for any purpose;

(3) deliver to Purchaser all original Leases and Lease files (or complete copies of such Leases or other documents where such documents are not in Seller's, Lend Lease's (as defined below) or Seller's management company's possession) and assign to Purchaser, and Purchaser shall assume from and after Closing, the landlord/lessor interest in and to the Leases by duly executed assignment and assumption agreement in the form attached to this agreement as Exhibit F;

(4) deliver to Purchaser all original Operating Agreements as well as all other documents referred to herein (or complete copies of such Operating Agreements or other documents where such documents are not in Seller's or Seller's management company's possession) and to the extent assignable, assign to Purchaser, and Purchaser shall assume from and after Closing, Seller's interest in the Operating Agreements and the other Intangibles by duly executed assignment and assumption agreement;

(5) deliver to Purchaser all original Tenant Estoppels (as such term is defined in Section 5.4(b) hereof) as are in Seller's possession. Notwithstanding anything contained in this Agreement to the contrary, in no event shall Seller be liable to Purchaser for, or deemed to be in default hereunder by reason of, its failure to obtain any Tenant Estoppel which Seller is required to deliver to Purchaser pursuant to Section
5.4(b) (it being understood, however, that such failure shall constitute a non-fulfillment of a condition precedent to Purchaser's obligation to close hereunder and Purchaser's remedies shall be as set forth in this Agreement);

(6) join with Purchaser to execute (i) a notice in form and content reasonably satisfactory to Purchaser and Seller which Purchaser shall send to each tenant under each of the Leases (A) informing such tenant of the sale of the Property and of the assignment to Purchaser of Seller's interest in, and obligations under, the Leases (including, if applicable any security deposits) effective from and after the Closing, and (B) directing that all rent and other sums payable after the Closing under each such Lease shall be paid as set forth in the notice, and (ii) a notice in form and content reasonably satisfactory to Purchaser and Seller which Purchaser shall send to each vendor under each of the

9

Operating Agreements in effect at Closing informing such vendor of the sale of the Property and of the assignment to Purchaser of Seller's interest in, and obligations under, the Operating Agreements and directing that all sums payable after the Closing under each such Operating Agreement shall be paid as set forth in the notice;

(7) deliver to Purchaser a certificate, dated as of the date of Closing and executed on behalf of Seller by a duly authorized officer thereof, stating that the representations and warranties of Seller contained in
Section 5.1 hereof are true and correct in all material respects as of the date of Closing (with appropriate modifications of those representations and warranties made in Section 5.1 hereof to reflect any changes therein including without limitation any changes resulting from actions under
Section 5.4 hereof) or identifying any representation or warranty which is not, or no longer is, true and correct and explaining the state of facts giving rise to the change. In no event shall Seller be liable to Purchaser for, or be deemed to be in default hereunder by reason of, any breach of representation or warranty which results from any change that (i) occurs between the Effective Date and the date of Closing and (ii) is (A) expressly permitted under the terms of this Agreement or (B) beyond the reasonable control of Seller to prevent; provided, however, that the occurrence of a change which is not expressly permitted in this Agreement shall constitute a non-fulfilment of a condition precedent to Purchaser's obligations to close under this Agreement, and Purchaser's remedies shall be as set forth in this Agreement. If, despite changes or other matters described in such certificate, Purchaser proceeds to the Closing and the Closing occurs, then Seller's representations and warranties set forth in this Agreement shall be deemed to have been modified by all statements made in such certificate;

(8) deliver to Purchaser such evidence as Purchaser's counsel and/or the Title Company may reasonably require as to the authority of the person or persons executing documents on behalf of Seller;

Purchaser shall cooperate with Seller for a period of seven (7) years after Closing in case of Seller's need in response to any tax audit, tax return preparation or litigation threatened or brought against Seller, by allowing Seller and its agents or representatives access, upon reasonable advance notice (which notice shall identify the nature of the information sought by Seller), and at reasonable times to examine and make copies of any and all instruments, files and records related to the

10

period of Seller's ownership of the Property and which Seller has delivered to Purchaser at Closing, which right shall survive the Closing;

(11) deliver to Purchaser possession and occupancy of the Property, subject to the Permitted Exceptions;

(12) deliver such additional documents as shall be reasonably required to consummate the transaction expressly contemplated by this Agreement, which additional documents may include transfer and recordation tax declarations and other tax certificates; and

(13) deliver an affidavit (and such other documents or instruments reasonably required by the Title Company) executed by Seller (and in form and substance reasonably satisfactory to Seller and Seller's counsel) (i) certifying against any work done or supplies delivered to the Property which might be grounds for a materialman's or mechanic's lien under or pursuant to applicable law, in form sufficient to enable the Title Company to delete any exception to any such lien, and (ii) which the Title Company may require to eliminate the pre-printed standard exceptions in the Title Policy;

(14) deliver such transfer and other tax declarations and returns and information returns, duly executed and sworn to by Seller as may be required of Seller by law in connection with the conveyance of the Property to Purchaser (including, but not limited to, Internal Revenue Service forms, if required);

(15) execute a closing statement setting forth the Purchase Price and all adjustments and prorations;

(16) deliver an updated Schedule 4.4(b)(8) (delinquent rents);

(19) such other documents as are required under this Agreement to be delivered by Seller at Closing.

IV.3 Purchaser's Obligations at Closing. At Closing, Purchaser shall:

(1) pay to Seller the full amount of the Purchase Price, as increased or decreased by prorations and adjustments as herein provided, in immediately available wire transferred federal funds pursuant to Section 1.5 above, it being agreed that at Closing the Earnest

11

Money shall be delivered to Seller and applied towards payment of the Purchase Price, and it being further understood that Seller shall receive such proceeds at its bank account no later than 3:00 p.m. Eastern time on the date of Closing, failing which the pro-rations shall be redetermined to coincide with the date on which said funds are received prior to 3:00
p.m. Eastern time (time being of the essence with respect to this subparagraph);

(2) join Seller in execution of the instruments described in Sections 4.2(c), 4.2(d), and 4.2(f) above;

(3) deliver to Seller a letter duly executed by Purchaser, confirming that Purchaser is not acquiring the Property with the assets of an employee benefit plan as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974 ("ERISA"), and, if Purchaser is unable or unwilling to make such a representation, then Purchaser shall be deemed to be in default hereunder, and Seller shall have the right to terminate this Agreement and to receive and retain the Earnest Money;

(4) deliver to Seller such evidence as Seller's counsel and/or the Title Company may reasonably require as to the authority of the person or persons executing documents on behalf of Purchaser; and

(5) deliver such additional documents as shall be reasonably required to consummate the transaction contemplated by this Agreement.

IV.4 Credits and Prorations.

(1) The following shall be apportioned with respect to the Property as of 12:01 a.m., on the day of Closing, as if Purchaser were vested with title to the Property during the entire day upon which Closing occurs:

(1) rents, if any, as and when collected (the term "rents" as used in this Agreement includes all payments due and payable by tenants under the Leases);

(2) taxes (including personal property taxes on the Personal Property) and assessments levied against the Property;

(3) payments under the Operating Agreements;

(4) gas, electricity, water, sewer and other utility charges in connection with the Property for which Seller is liable, if any, such charges to be apportioned at Closing on the basis of the most recent meter reading occurring prior to Closing (and Seller shall use commercially reasonable efforts to cause the utilities to read the meters as close as possible to the date of Closing); and

12

(5) any other operating expenses or other items pertaining to the Property which are customarily prorated between a purchaser and a seller in the area in which the Property is located.

(2) Notwithstanding anything contained in the foregoing provisions:

(1) At Closing, Seller shall credit to the account of Purchaser the amount of all cash security deposits held by Seller, $608 (which represents an additional security deposit for Belay & Belay Investment, Inc.) and any interest on such security deposits if and only to the extent required by the applicable Lease.

(2) Any taxes paid at or prior to Closing shall be prorated based upon the amounts actually paid. If taxes and assessments for the current year have not been paid before Closing, Seller shall be charged at Closing an amount equal to that portion of such taxes and assessments (together with interest and penalties thereon) which relates to the period before Closing and Purchaser shall pay the taxes and assessments prior to their becoming delinquent. Any such apportionment made with respect to a tax year for which the tax rate or assessed valuation, or both, have not yet been fixed shall be based upon the tax rate and/or assessed valuation last fixed. To the extent that the actual taxes and assessments for the current year differ from the amount apportioned at Closing, the parties shall make all necessary adjustments by appropriate payments between themselves following Closing.

(3) Charges referred to in Section 4.4(a) above which have been contracted for by a Tenant to a third party and are payable by such Tenant directly to said third party shall not be apportioned hereunder, and Purchaser shall accept title subject to any of such charges unpaid and Purchaser shall look solely to the tenant responsible therefor for the payment of the same.

(4) Seller shall receive the entire advantage of any discounts for the prepayment by it of any taxes, water rates or sewer rents.

(5) As to gas, electricity and other utility charges referred to in Section 4.4(a)(iv) above, Seller may on notice to Purchaser elect to pay one or more of all of said items accrued to the date hereinabove fixed for apportionment directly to the person or entity entitled thereto, and to the extent Seller so elects, such item shall not be apportioned hereunder, and Seller's obligation to pay such item directly in such case shall survive the Closing.

(6) The Personal Property is included in this sale, without further charge.

13

(7) If (i) Purchaser approves any new Lease, or the renewal or extension of an existing Lease which is not provided for thereunder, which approval includes an approval of the costs to be incurred by the landlord on account thereof, or (ii) a Tenant exercises, after the Effective Date, a renewal or extension of an existing Lease pursuant to a right set forth therein, which exercise requires the landlord to incur certain costs on account thereof, then Purchaser shall be responsible for such costs and Seller shall have no responsibility therefor. If, as of the date of Closing, Seller shall have paid any costs for which Purchaser is responsible pursuant to the foregoing sentence, Purchaser shall reimburse Seller therefor at Closing. The provisions of this Section shall survive the Closing.

(8) All moneys received from Tenants from and after the date of Closing shall belong to Purchaser and shall be applied by Purchaser to current rents and other charges under the Leases. After application of such moneys to current rents and charges, Purchaser agrees to remit to Seller any excess amounts paid by a Tenant to the extent that such Tenant was in arrears in the payment of rent prior to the Closing. Attached hereto as Schedule 4.4(b)(8) is a schedule of delinquent rents as of the Effective Date, which schedule shall be updated as of the date of Closing.

(9) At the Closing, Seller shall deliver to Purchaser a list of additional rent, however characterized, under each Lease, including without limitation, real estate taxes, electrical charges, utility costs and operating expenses (collectively, "Additional Rents") billed to Tenants for the calendar year in which the Closing occurs (both on a monthly basis and in the aggregate), the basis for which the monthly amounts are being billed and the amounts incurred by Seller on account of the components of Additional Rents for such calendar year. Upon the reconciliation by Purchaser of the Additional Rents billed to Tenants, and the amounts actually incurred for such calendar year, Seller and Purchaser shall be liable for overpayments of Additional Rents, and shall be entitled to payments from Tenants, as the case may be, on a pro rata basis based upon each party's period of ownership during such calendar year. In addition, Seller has advised Purchaser that Brooks Brothers, Inc., is obligated to pay percentage rent in accordance with its lease, and upon receipt by Purchaser of any percentage rent which pertains to the period of time prior to Closing, Purchaser shall promptly remit to Seller its proportionate share thereof.

(10) With respect to the ongoing tenant improvement work being performed for Radio Free Europe, Seller shall provide to Purchaser at Closing a credit in the amount of any sums remaining to be paid by Seller pursuant to such

14

tenants' leases. With respect to the ongoing tenant improvement work being performed for Joseph M. Del Balzo, Seller shall credit to Purchaser at Closing an amount equal to 120% of any sums outstanding for such work as of Closing, and the unused portion of such credit shall be reimbursed to Seller promptly after completion and acceptance by Joseph M. Del Balzo of the tenant improvement work for such tenant. The amount of the credit due on account of such work shall be based on a letter from the contractor setting forth the amounts owed to it. The credit shall also include amounts due for the construction management fee for such work. With respect to Seller's obligations to such tenants for the aforesaid tenant improvement work, Seller shall provide to Purchaser at Closing such written documentation as Purchaser may request for the purpose of establishing the amounts remaining to be paid to such tenants in connection with such work, Seller acknowledging that Purchaser is requesting the estoppel from Radio Free Europe to set forth the amount still due.

(3) Any errors in calculations or adjustments shall be corrected or adjusted as soon as practicable after the Closing. The provisions of this
Section 4.4 shall survive Closing.

IV.5 Closing Costs. Seller shall pay: (a) the fees of any counsel representing it in connection with this transaction; (b) one-half (1/2) of any escrow fee which may be charged by the Escrow Agent or Title Company; (c) one-half (1/2) of any transfer tax, recordation tax, grantor's tax, documentary stamp tax or similar tax which becomes payable by reason of the transfer of the Property; (d) the customary fees for recording the deed conveying the Property to Purchaser; and (e) all costs incurred to repay or satisfy all liens as specifically required by Section 2.3. Purchaser shall: (u) pay the fees of any counsel representing Purchaser in connection with this transaction; (v) pay the premium for the Title Policy to be issued to Purchaser by the Title Company at Closing;
(w) pay for the cost of changes to the Survey requested by Purchaser; (x) pay one-half (1/2) of any transfer tax, recordation tax, grantor's tax, documentary stamp tax or similar tax which becomes payable by reason of the transfer of the Property; and (y) pay one-half (1/2) of any escrow fees charged by the Escrow Agent or Title Company. All other costs and expenses incident to this transaction and the closing thereof shall be paid by the party incurring such costs and expenses. The provisions of this Section 4.5 shall survive the Closing or any early termination of this Agreement.

IV.6 Conditions Precedent to Obligation of Purchaser. The obligation of Purchaser to consummate the transaction hereunder shall be subject to the fulfillment on or before the date of Closing of all of the following conditions, any or all of which may be waived by Purchaser in its sole discretion:

(1) Seller shall have delivered to Purchaser all of the items required to be delivered to Purchaser pursuant to the terms of this Agreement, including but not limited to, those

15

provided for in Section 4.2.

(2) All of the representations and warranties of Seller contained in this Agreement shall be true and correct in all material respects as of the date of Closing.

(3) Seller shall have performed and observed, in all material respects, all covenants and agreements of this Agreement to be performed and observed by Seller as of and to the date of Closing.

(4) The Title Company shall be unconditionally prepared to issue to Purchaser a Title Policy which meets the requirements of this Agreement.

(5) The Property shall be in substantially the same condition as exists as of the last day of the Inspection Period, subject to (i) ordinary wear and tear, and (ii) the provisions of Article VII, it being understood that Seller shall not be required to replace any building systems or make any capital improvements except as expressly required by this Agreement.

(f) Zuckerman, Spaeder, Goldstein, Taylor & Kolker ("Zuckerman Spaeder") shall have entered into a written and binding agreement in form and substance reasonably satisfactory to Purchaser identifying the expansion space on the 5th floor which Zuckerman Spaeder will occupy, which space shall be unoccupied and legally allowed to be occupied; such agreement shall also provide for a renewal of the space currently occupied by Zuckerman Spaeder on the 8th floor, and shall provide that the term of the expansion space and the renewal space shall be coterminous with the term of the balance of the space occupied by Zuckerman Spaeder at the Property. Purchaser shall have the right to reasonably approve the configuration of the expansion space identified by Zuckerman Spaeder, and Purchaser shall not be deemed to be unreasonable if the lineal footage along Connecticut Avenue identified by Zuckerman Spaeder is increased by more that 5% from the space plan annexed hereto as Exhibit H. The remaining vacant space on the fifth floor shall be reasonably capable of being separately demised and leased in the ordinary course of business, shall be reasonably appropriate for office use, and shall contain not less than 5,476 square feet. Such agreement shall set forth Zuckerman Spaeder's agreement on its rent and any tenant improvement allowances for the expansion space, and the rent for the renewal space during the renewal term, and shall specifically acknowledge that such agreement satisfies Zuckerman Spaeder's expansions rights under its Lease. At Closing Purchaser shall receive a credit from Seller towards the Purchase Price equal to the sum of (i),
(ii) and (iii):

(i) an amount equal to $6.32 multiplied by the number of square feet remaining on the 5th floor following approval by Purchaser of the expansion space on such floor to be occupied by Zuckerman Spaeder, further multiplied by 5 (reflecting an agreed upon assumed 5 year term);

16

plus

(ii) the sum of (A) with respect to the expansion space on the fifth floor, the positive difference between $31.32 per square foot of space to be leased by Zuckerman Spaeder and the per square foot fixed rent to be paid by Zuckerman Spaeder during the first year of the expansion term, multiplied by the square footage of such expansion space and further multiplied by the annualized term of the expansion, plus (B) with respect to the renewal space on ---- the eighth floor, the positive difference between $31.32 per square foot of space to be leased by Zuckerman Spaeder on the eighth floor and the per square foot fixed rent to be paid by Zuckerman Spaeder during the first year of the renewal term, multiplied by the square footage of such renewal space and further multiplied by the annualized term of the renewal; plus

(iii) the sum of the amount, if any, by which the tenant improvement allowance (including any sprinklering costs) for Zuckerman Spaeder's fifth floor space exceeds $20 per square foot, multiplied by the square footage of such expansion space, plus the amount, if any, by which the tenant improvement allowance (including any sprinklering costs) for Zuckerman Spaeder's eighth floor space exceeds $10 per square foot, multiplied by the square footage of such renewal space. In the event that the agreement with Zuckerman Spaeder requires that the landlord under Zuckerman Spaeder's Lease is to perform the tenant improvement work, then, notwithstanding anything to the contrary contained in this clause (f)(iii), Purchaser and Seller shall mutually agree upon an amount that is equal to 150% of the estimated cost of such tenant improvement work (including a construction management fee), which amount shall be held in escrow pursuant to an escrow agreement mutually satisfactory to Purchaser and Seller, and Purchaser shall not be entitled to a credit pursuant to this clause (iii). The cost of Zuckerman Spaeder's tenant improvement work shall be paid from such escrow account, and any balance remaining after the completion of such work shall promptly be paid to Seller.

The provisions of this Section 4.6(f) shall survive Closing indefinitely.

In lieu of the expansion rights with respect to the fifth floor, Seller agrees that if by 5:00 p.m. on Friday, July 2, 1999, Purchaser advises Seller in writing that Purchaser will approve of Zuckerman Spaeder occupying a portion of the 3rd floor equal to the portion which would otherwise be taken on the 5th floor, then if by Closing Seller delivers an agreement from Zuckerman Spaeder satisfying all of the terms and conditions set forth above but which provides for Zuckerman Spaeder occupying a portion of the 3rd floor rather than a portion of the 5th floor, and the terms and conditions of such occupancy

17

provide for a fixed rent of $28.70 per square foot in the first year, increasing 2% per year, a 5 year term, and tenant improvement concessions not to exceed $20 per square foot, then Seller will credit Purchaser with $302,175 on account of the credits described in (i) and (ii) above and the credit on account of the tenant improvement allowance for the fifth floor as described in (iii) above.

(6) Seller shall have paid the second half real estate brokerage commissions payable with respect to the lease to Joseph M. Del Balzo and provided Purchaser with written evidence thereof.

(7) Radio Free Europe shall have either vacated the temporary space which it is occupying pursuant to that certain letter dated March 16, 1999, or agreed to vacate the temporary space within 15 days of the Closing, so long as such agreement is confirmed in writing and a copy thereof is provided to Purchaser.

(8) Seller shall have delivered to Purchaser a letter from the District of Columbia Fire Department clarifying that there is only one (1) underground storage tank at the Property.

(9) Seller shall have delivered or caused to be delivered to Purchaser a reliance letter from Levine-Fricke-Recon (for the Phase I Report (as defined below)) in form and substance reasonably satisfactory to Purchaser.

(10) All Leases under which the Required Tenants (as defined below) lease space shall be in full force and effect.

IV.7 Conditions Precedent to Obligation of Seller. The obligation of Seller to consummate the transaction hereunder shall be subject to the fulfillment on or before the date of Closing of all of the following conditions, any or all of which may be waived by Seller in its sole discretion:

(1) Seller shall have received the Purchase Price as adjusted pursuant to and payable in the manner provided for in this Agreement.

(2) Purchaser shall have delivered to Seller all of the items required to be delivered to Seller pursuant to the terms of this Agreement, including but not limited to, those provided for in Section 4.3.

(3) All of the representations and warranties of Purchaser contained in this Agreement shall be true and correct in all material respects as of the date of Closing.

65535RT65535CLE VREPRESENTATIONS, WARRANTIES AND COVENANTS

18

V.1 Representations and Warranties of Seller. Seller hereby makes the following representations and warranties to Purchaser:

(1) Organization and Authority. Seller has been duly organized and is validly existing under the laws of New York. Seller has the full right and authority to enter into this Agreement and, subject to the provisions of
Section 10.6 hereof, to transfer all of the Property to be conveyed by Seller pursuant hereto and to consummate or cause to be consummated the transactions contemplated herein to be made by Seller. The person signing this Agreement on behalf of Seller is authorized to do so. This Agreement, when duly executed and delivered, will be the legal, valid and binding obligation of Seller, enforceable in accordance with the terms of this Agreement. The performance by Seller of its duties and obligations under this Agreement and the documents and instruments to be executed and delivered by it hereunder will not conflict with, or result in a breach of, or default under, any provision of any of the organizational documents of Seller or any agreements, instruments, decrees, judgments, injunctions, orders, writs, laws, rules or regulations, or any determination or award of any court or arbitrator, to which Seller is a party or by which its assets are or may be bound.

(2) Pending Actions. To Seller's knowledge, there is no pending action, suit, arbitration, unsatisfied order or judgment, governmental investigation or proceeding against the Property or the transaction contemplated by this Agreement (nor, to Seller's knowledge, has any such matter been threatened in writing), which, if adversely determined, could individually or in the aggregate have an effect on the Property or any portion thereof or which could in any material way interfere with the consummation by Seller of the transaction contemplated by this Agreement or which is not covered by insurance.

(3) Leases. Seller is the lessor or landlord or the successor lessor or landlord under the Leases. Seller has delivered to Purchaser true, correct and complete copies of all of the Leases and any guaranties thereof. Except as set forth in the Lease Schedule, there are no other leases or occupancy agreements affecting the Property. Except as otherwise set forth in the Leases, to Seller's knowledge, no presently effective rent concessions have been given to any tenants and no rent has been paid in advance by any tenants respecting a period subsequent to the Closing. No tenants have asserted in writing any claims, defenses or offsets to rent accruing from and after the date of Closing. To Seller's knowledge, except as disclosed to Purchaser in writing, no default, delinquency or breach exists on the part of any tenant, and to Seller's knowledge, no condition exists which, with the passage of time or the giving of notice, or both, will become a default. There are no defaults or breaches on the part of Seller, as the landlord under any Lease. In the event that any Tenant Estoppel delivered to Purchaser with respect to any Lease shall contain any statement of fact, information or other matter which is inconsistent with the matters stated in Seller's representations in this Section 5.1(c), the Tenant Estoppel shall control and Seller shall have no liability for any claim based upon a breach of

19

representation regarding such statement of fact, information or other matter contained in the Tenant Estoppel. Notwithstanding anything to the contrary contained in this Agreement, Seller does not represent or warrant that any particular Lease will be in force or effect at Closing or that the tenants under the Leases will have performed their obligations thereunder. The termination of any Lease prior to Closing by reason of the tenant's default shall not affect the obligations of Purchaser under this Agreement in any manner or entitle Purchaser to an abatement of or credit against the Purchase Price or give rise to any other claim on the part of Purchaser, except that such event with respect to a Required Tenant shall constitute a non-fulfillment of a condition precedent to Purchaser's obligation to close hereunder and Purchaser's remedies shall be as set forth in this Agreement.

There are no lease brokerage agreements, leasing commission agreements or other agreements providing for payments of any amounts for leasing activities or procuring tenants with respect to the Property which will become due and payable from and after the date of Closing other than as disclosed in Exhibit G attached hereto and made a part hereof. In furtherance, and not in limitation, of the foregoing, Seller further represents that there are no existing agreements with brokers concerning expansions or renewals of existing Leases, except for the lease commissions payable to Fred Ezra and Trammel Crow Real Estate Services (and disclosed in Exhibit G), which lease commissions shall be paid prior to Closing pursuant to Section 4.6(g).

V.2 Knowledge Defined.

(a) References to the "knowledge" of Seller shall refer only to the actual knowledge of the Designated Employee (as hereinafter defined) of Lend Lease Real Estate Investments, Inc. ("Lend Lease"), the manager of the Property for Seller, and shall not be construed (by imputation or otherwise) to refer to the knowledge of Seller, Lend Lease or any affiliate of either of them, to any property manager, or to any other officer, agent, manager, representative or employee of Seller or Lend Lease or any affiliate thereof or to impose upon such Designated Employee any duty to investigate the matter to which such actual knowledge, or the absence thereof, pertains; provided, however, that the Designated Employee has contacted Keith Lipton, Jones Lang LaSalle's (the property manager) representative at the Property, and requested that Mr. Lipton review Jones Lang LaSalle's files relating to the Property and the representations and warranties set forth in Section 5.1, and Mr. Lipton has advised the Designated Employee that he has no actual knowledge of any fact or circumstance which would cause any representation made to the knowledge of Seller to be false.

Daly, Jr. Seller represents and warrants that the Designated Employee is the person currently in the employ of either Seller or Lend Lease who possesses the knowledge with respect to the matters contained herein.

(b) References to the "knowledge" of Purchaser shall refer only to the actual knowledge of David Parisier ("Purchaser's Representative") and shall not be construed (by imputation or otherwise) to refer to the knowledge of Purchaser or

(a) The representations and warranties of Seller set forth in Section 5.1, as updated by the certificate of Seller to be delivered to Purchaser at Closing in accordance with Section 4.2(g) hereof, shall survive Closing for a period of two hundred seventy (270) days. No claim for a breach of any representation or warranty of Seller shall be actionable or payable (i) if the breach in question results from or is based on a condition, state of facts or other matter which was known to Purchaser's Representative prior to Closing, (ii) unless the valid claims for all such breaches collectively aggregate more than Fifty Thousand Dollars ($50,000), in which event the full amount of such claims shall be actionable, and (iii) unless written notice containing a description of the specific nature of such breach shall have been given by Purchaser to Seller prior to the expiration of said 270-day period and an action shall have been commenced by Purchaser against Seller within sixty (60) days after the termination of the survival period provided for above in this
Section 5.3. Purchaser agrees to first seek recovery under any insurance policies, service contracts and Leases prior to seeking recovery from Seller, and Seller shall not be liable to Purchaser if Purchaser's claim is satisfied from such insurance policies, service contracts or Leases.

(b) As used herein, the term "Cap" shall mean an amount, in total aggregate, equal to $1,500,000.

During the foregoing 270-day period, the Value Enhancement Fund shall maintain $1,500,000 of assets (net of liabilities) for the purpose of satisfying any obligations under this Section 5.3. Notwithstanding anything to the contrary contained herein, Seller shall indemnify, defend and hold harmless Purchaser from and against all claims, liabilities, losses, damages, penalties and costs (including, without limitation, reasonable attorneys' fees) which Purchaser may incur as a result of Seller's failure to pay third parties or Seller's breach of any

obligation or agreement with the same, which indemnification shall survive the Closing and shall not be subject to any monetary limitations.

V.4 Covenants of Seller. Seller hereby covenants with Purchaser as follows:

(1) From the Effective Date hereof until the Closing or earlier termination of this Agreement, Seller shall use commercially reasonable efforts to operate and maintain the Property in a manner generally consistent with the manner in which Seller has operated and maintained the Property prior to the date hereof. In addition, Seller shall use reasonable efforts to preserve for Purchaser the relationships of Seller with the Tenants, suppliers and others having on-going relationships with the Property. Seller will complete any capital expenditure program currently in process or anticipated to be completed. Seller will not defer taking any actions or spending any of its funds, or otherwise manage the Property differently, due to the pending sale of the Property

(2) Seller shall use commercially reasonable efforts (but without obligation to incur any cost or expense) to obtain and deliver to Purchaser prior to Closing, a written estoppel certificate (each, a "Tenant Estoppel" and collectively, the "Tenant Estoppels"), signed by each tenant occupying space in the Property, which Tenant Estoppels (i) shall be in the form of Exhibit E attached hereto and made a part hereof
(or, alternatively, in the form, required by the applicable Lease); (ii) shall be dated not more than thirty (30) days prior to the date of the Closing; (iii) shall not contain any adverse statements (other than of a de minimis nature) relating to the operation or condition of the Property or assert a material default on the part of Seller; and (iv) shall state that all rent due under such Tenant's Lease has been paid through the month in which the Closing occurs.

DelBalzo.

(3) Prior to execution by Seller of any renewal or expansion of an existing Lease (except in connection with the exercise of a renewal or expansion right provided in such Lease) or of any new Lease which Seller wishes to execute between the Effective Date and the date of Closing, Seller shall submit the relevant documentation to Purchaser for Purchaser's approval. Prior to the expiration of the Inspection Period, Purchaser agrees that it shall not unreasonably withhold or delay its consent to any proposed lease or amendment; and after the expiration of the Inspection Period, Purchaser may grant or withhold its consent in its sole discretion. In any event, Purchaser agrees to notify Seller in writing within five (5) business days after its receipt thereof of either its approval or disapproval thereof, as well as any costs to be incurred by the landlord thereunder in connection therewith. In the event Purchaser fails to notify Seller in writing of its approval or disapproval within the five (5) day time period for such purpose set forth

26

above, such failure shall be deemed the disapproval by Purchaser. At Closing, Purchaser shall reimburse Seller for any costs paid by Seller on account of such renewal, expansion or new Lease approved by Purchaser.

(4) If, prior to the Closing Date, Seller shall have received from (i) any insurance company which issued a policy with respect to the Property, (ii) any board of fire underwriters or other body exercising similar functions, or (iii) the holder of any mortgage, any notice requiring or recommending any repair work to be done on the Property, Seller shall perform the same expeditiously and diligently at its own cost and expense prior to the Closing Date, but only so long as the cost thereof does not exceed $50,000 in the aggregate.

(5) Seller shall: (1) Promptly notify Purchaser of, and promptly deliver to Purchaser, a copy of any Notice which Seller may receive, on or before the date of Closing, from any Governmental Authority concerning a violation of Environmental Laws or Discharge (as defined in Section 5.8 below) of Hazardous Substances; and (2) contemporaneously with the signing and delivery of this Agreement, and subsequently, promptly upon receipt by Seller or its representatives, deliver to Purchaser a true and complete copy of all Environmental Documents.

(6) In addition to the foregoing, Seller shall not: (1) enter into any agreement requiring Seller to do work for any Tenant after the Closing Date without first obtaining the prior written consent of Purchaser; (2) Accept the surrender of any Service Contract or Lease, or grant any concession, rebate, allowance or free rent; (3) apply any Security Deposits with respect to any Tenant in occupancy on the Closing Date; (4) Renew, extend or modify any of the Operating Agreements without the prior written consent of Purchaser; (5) Remove any Personal Property located in or on the Property, except as may be required for repair and replacement.

Seller agree to remove, or cause to be removed, at its sole cost and expense, any lien or encumbrance which appears of record after the date on which the Title Commitment was issued and is not shown on the Title Commitment.

(7) Upon request of Purchaser at any time after the date hereof (but without any cost or expense to Seller), Seller shall assist Purchaser in its preparation of audited financial statements, statements of income and expense, and such other documentation as Purchaser may reasonably request, covering the period of Seller's ownership of the Property.

27

(8) Up to and including the Closing Date, Seller agrees to maintain and keep such hazard, liability and casualty insurance policies in full force and effect in such amounts and covering such risks sufficiently to protect the Property and to protect, to a reasonable and prudent extent, the owner of the Property, in such amounts as are required so as not to be deemed a co-insurer, and for actual replacement cost, against any loss, damage, claim or liability.

(9) Seller shall cancel, at its sole cost and expense, those Operating Agreements which Purchaser elects not to assume and which can, by their terms, be terminated prior to the Closing without the payment of any termination or other penalties or charges of any type or nature.

(10) Seller shall permit Purchaser and its authorized representatives to inspect the Books and Records of its operations concerning the Property at all reasonable times and on reasonable advance notice. The foregoing shall survive the Closing.

(11) All violations of statutes, ordinances, rules, regulations, orders, codes, directives or requirements affecting the Property, whether or not such violations are now noted in the records of or have been issued by any Governmental Authorities, shall be complied with by Seller prior to the Closing and the Property shall be conveyed free of any such violations, including, without limitation, violations of Environmental Laws, provided that the aggregate cost to Seller of complying with the foregoing shall not exceed $50,000. If the cost to cure said violations exceeds $50,000, Purchaser shall have the right to either (i) terminate this Agreement and receive a full refund of the Earnest Money or (ii) proceed to Closing, and at such event Purchaser shall receive a $50,000 credit from Seller. Notwithstanding the immediately preceding sentence, in the event that Purchaser elects to terminate this Agreement pursuant to clause (i) above, then Seller shall have the right to cure said violations by paying the entire cost to cure said violation and Purchaser and Seller shall proceed to Closing (and Purchaser's election to terminate this Agreement shall be of no force or effect).

Purchaser hereby assumes full responsibility for such inspections and, except for claims based on representations or warranties contained in Section 5.1(i), irrevocably waives any claim against Seller arising from the presence of Hazardous Substances on the Property. If Purchaser terminates this Agreement during the Inspection Period, Purchaser shall also furnish to Seller copies of any other reports received by Purchaser relating to any other inspections of the Property conducted on Purchaser's behalf, if any (including, specifically, without limitation, any reports analyzing compliance of the Property with the provisions of the Americans with Disabilities Act ("ADA"), 42 U.S.C. ss.12101, et seq., if applicable), other than those reports which are confidential or proprietary in nature.

If Purchaser does not terminate this Agreement within such ten-day period, then Purchaser shall be deemed to have elected to proceed with Closing, in which event Seller shall, at Seller's option, either (a) perform any necessary repairs, or (b) assign to Purchaser all of Seller's right, title and interest to any claims and proceeds Seller may have with respect to any casualty insurance policies or condemnation awards relating to the premises in question. In the event that Seller elects to perform repairs upon the Property, Seller shall use reasonable efforts to complete such repairs promptly and the date of Closing shall be extended a reasonable time in order to allow for the completion of such repairs. If Seller elects to assign a casualty claim to Purchaser, the Purchase Price shall be reduced by an amount equal to the deductible amount under Seller's insurance policy. Upon Closing, full risk of loss with respect to the Property shall pass to Purchaser.

If Purchaser does not give notice to Seller of Purchaser's reasons for disapproving an architect within five (5) business days after receipt of notice of the proposed architect, Purchaser shall be deemed to have approved the architect selected by Seller.

For purposes of this Agreement and the transactions contemplated hereunder, Seller and Purchaser agree that they and their respective agents and representatives shall be bound by the terms and conditions of that certain letter agreement dated March 10, 1999, between Purchaser and the Broker (as hereinafter defined) and attachments thereto (collectively, the "Confidentiality Agreement"), and the terms and conditions of the Confidentiality Agreement are incorporated herein its entirety. In the event of a breach or threatened breach of this Section 10.1 by Seller or Purchaser or their agents or representatives, the non-breaching party shall be entitled to an injunction restraining the breaching party or its agents or representatives from disclosing, in whole or in part, such confidential information. Nothing herein shall be construed as prohibiting the non-breaching from pursuing any other available remedy at law or in equity for such breach or threatened breach. The provisions of this Section 10.1 shall survive Closing or any early termination of this Agreement

X.2 Public Disclosure. Prior to Closing, any release to the public of information with respect to the sale contemplated herein or any matters set forth in this Agreement will be made only in the form approved by Purchaser and Seller and their respective counsel, which approval shall not be unreasonably withheld or delayed. The provisions of this Section shall survive Closing or any early termination of this Agreement.

35

X.3 Discharge of Obligations. The acceptance of the Deed by Purchaser shall be deemed to be a full performance and discharge of every representation and warranty made by Seller herein and every agreement and obligation on the part of Seller to be performed pursuant to the provisions of this Agreement, except those which are herein specifically stated to survive Closing.

X.4 Assignment. Purchaser may not assign its rights under this Agreement without first obtaining Seller's written approval, which approval may be given or withheld in Seller's sole discretion; provided, however, that Purchaser may assign this Agreement to an entity which is affiliated (i) with Purchaser or
(ii) with any entity under the common control of the entity controlling Purchaser. In the event of an assignment by Purchaser to any such entity, Purchaser shall advise Seller prior to the Closing. Under no circumstances shall Purchaser have the right to assign this Agreement to any person or entity owned or controlled by an employee benefit plan if Seller's sale of the Property to such person or entity would, in the reasonable opinion of Seller's ERISA advisor, create or otherwise cause a "prohibited transaction" under ERISA. In the event Purchaser assigns this Agreement or transfers any ownership interest in Purchaser, and such assignment or transfer would make the consummation of the transaction hereunder a "prohibited transaction" under ERISA and necessitate the termination of this Agreement then, notwithstanding any contrary provision which may be contained herein, Seller shall have the right to pursue any remedy available at law or in equity as a result of such assignment or transfer. Any transfer, directly or indirectly, of any stock, partnership interest or other ownership interest in Purchaser without Seller's written approval, which approval may be given or withheld in Seller's sole discretion, shall constitute a default by Purchaser under this Agreement.

X.5 Notices. Any notice pursuant to this Agreement shall be given in writing by
(a) personal delivery, or (b) reputable overnight delivery service with proof of delivery, or (c) United States Mail, postage prepaid, registered or certified mail, return receipt requested, or (d) legible facsimile transmission sent to the intended addressee at the address set forth below, or to such other address or to the attention of such other person as the addressee shall have designated by written notice sent in accordance herewith, and shall be deemed to have been given either at the time of personal delivery, or, in the case of expedited delivery service or mail, as of the date of first attempted delivery at the address and in the manner provided herein, or, in the case of facsimile transmission, as of the date of the facsimile transmission provided that an original of such facsimile is also sent to the intended addressee by means described in clauses (a), (b) or (c) above.

X.6 Binding Effect. This Agreement shall not be binding in any way upon Seller unless and until (a) Seller shall execute and deliver the same to Purchaser, (b) each stage of Seller's investment approval process has approved this transaction, and (c) Seller's Investment Committee has thereafter given its written approval thereof. If (A) Seller has not given Purchaser written notice
(the "Approval Notice") of such approvals on or before 3:00 p.m. (Eastern time)
June 30, 1999 (the "Approval Deadline"), or (B) prior to the Approval Deadline Seller notifies Purchaser in writing that this Agreement has been disapproved by the persons or entities referred to in clauses (b) or (c) of the preceding sentence, then (x) this Agreement shall be deemed terminated and Purchaser shall be entitled to the return of the Earnest Money and (y) Seller shall reimburse Purchaser for its reasonable costs and expenses incurred up to and including the date of such termination (including reasonable attorneys' fees), provided that such reimbursement shall not exceed $50,000. It is understood and agreed that at each stage of Seller's investment approval process, Seller or its investment advisor, Lend Lease, shall each have the right, in its unfettered discretion, to disapprove the transaction contemplated by this Agreement for any reason whatsoever, without obligation thereafter to proceed to the next stage of Seller's investment approval process. Seller's approval of this Agreement shall be evidenced only by both Seller's execution of this Agreement and Seller's sending of the Approval Notice to Purchaser prior to the Approval Deadline and, accordingly, Purchaser acknowledges and agrees that Purchaser cannot and will not rely upon any other statement or action of Seller or its representatives as evidence of Seller's approval of this Agreement or the subject matter hereof.

X.7 Modifications.

Purchaser shall deliver to each and every tenant of the Property under a Lease thereof a signed statement acknowledging Purchaser's receipt and responsibility for each tenant's security deposit (to the extent delivered by Seller to Purchaser at Closing), if any, all in compliance with and pursuant to the applicable provisions of applicable law.

X.9 Calculation of Time Periods. Unless otherwise specified, in computing any period of time described in this Agreement, the day of the act or event after which the designated period of time begins to run is not to be included and the last day of the period so computed is to be included, unless such last day is a Saturday, Sunday or legal holiday under the laws of the District of Columbia, in which event the period shall run until the end of the next day which is

It shall be necessary to account for only one such counterpart in proving this Agreement. Faxed signatures shall have the same binding effect as original signatures.

PURCHASER AND SELLER AGREE THAT THE PROVISIONS OF THIS SECTION 10.15 SHALL SURVIVE THE CLOSING OF THE TRANSACTION CONTEMPLATED HEREUNDER OR THE EARLY TERMINATION OF THIS AGREEMENT.

For further information, Purchaser can contact a soil testing laboratory, the District of Columbia Department of Environmental Services, or the Soil Conservation Service of the United States Department of Agriculture.

X.24 UST Disclosure. In accordance with the requirements of the District of Columbia Underground Storage Tank Management Act of 1990, as amended by the District of Columbia Underground Storage Tank Management Act of 1990 Amendment Act of 1992 (D.C.
