ITEM 1. BUSINESS

GENERAL

Mack-Cali Realty Corporation, previously Cali Realty Corporation, (together with
its subsidiaries, the "Company") is a fully-integrated, self-administered and
self-managed real estate investment trust ("REIT") that owns and operates a
portfolio comprised predominantly of Class A office and office/flex properties
located primarily in the Northeast and Southwest, as well as commercial real
estate leasing, management, acquisition, development and construction
businesses. As of December 31, 1997, the Company owned 189 properties,
consisting of 118 office properties (the "Office Properties"), 59 office/flex
properties (the "Office/Flex Properties"), and six industrial/warehouse
properties (the "Industrial/Warehouse Properties"), encompassing an aggregate of
approximately 22.0 million square feet, as well as two multi-family residential
properties, two stand-alone retail properties, and two land leases
(collectively, the "Properties"). See "Business -- Recent Developments." As of
December 31, 1997, the Office Properties, Office/Flex Properties and
Industrial/Warehouse Properties in the aggregate, were approximately 95.8
percent leased to approximately 2,300 tenants. The Company believes that its
Properties have excellent locations and access and are well-maintained and
professionally managed. As a result, the Company believes that its Properties
attract high quality tenants and achieve among the highest rental, occupancy and
tenant retention rates within their markets.

The Company's strategy has been to focus its development and ownership of office
properties in sub-markets where it is, or can become, a significant and
preferred owner and operator. The Company will continue this strategy by
expanding, primarily through acquisitions, initially into sub-markets where it
has, or can achieve, similar status. Consistent with its growth strategy, during
1997, the Company acquired 132 properties, primarily office and office/flex
properties, for an aggregate acquisition cost of approximately $1.8 billion,
including the December 1997 acquisition of 54 Class A office properties (the
"Mack Properties"), aggregating approximately 9.2 million square feet, from The
Mack Company and Patriot American Office Group for a total cost of approximately
$1.1 billion (the "Mack Transaction"). Additionally, in January 1997 the Company
completed the acquisition of 65 properties, aggregating approximately 4.1
million square feet, (the "RM Properties") of the Robert Martin Company, LLC
("RM") and affiliates for approximately $450.0 million the ("RM Transaction").
See "Business -- Recent Developments." Management believes that the recent trend
towards increasing rental and occupancy rates in office buildings in the
Company's sub-markets continues to present significant opportunities for
growth. The Company may also develop properties in such sub-markets,
particularly with a view towards potential utilization of certain vacant land
recently acquired or on which the Company holds options. Management believes
that its extensive market knowledge provides the Company with a significant
competitive advantage which is further enhanced by its strong reputation for and
emphasis on delivering highly responsive management services, including direct
and continued access to the Company's senior management. See "Business -- Growth
Strategies."

The Company's ten largest tenants, based on actual rent billings in December
1997, are AT&T Corporation, AT&T Cellular Services, Donaldson, Lufkin & Jenrette
Securities Corp., Dow Jones Telerate Systems Inc., Prentice-Hall Inc., American
Institute of Certified Public Accountants (AICPA), Allstate Insurance Company,
CMP Media Inc., Toys 'R' Us, Inc., and KPMG Peat Marwick LLP. The average age of
the Office Properties, Office/Flex Properties and Industrial/Warehouse
Properties is approximately 15, 15 and 36 years, respectively.

Cali Associates, the entity to whose business the Company succeeded in 1994, was
founded by John J. Cali, Angelo R. Cali and Edward Leshowitz (the "Founders")
who have been involved in the development, leasing, management, operation and
disposition of commercial and residential properties in Northern and Central New
Jersey for over 40 years and have been primarily focusing on office building
development for the past fifteen years. In addition to the Founders, the
Company's executive officers have been employed by the Company and its
predecessor for an average of approximately 10 years. The Company and its
predecessor have built approximately four million square feet of office space,
more than one million square feet of industrial facilities and over 5,500
residential units.

Upon the completion of the Mack Transaction on December 11, 1997, the Company
became one of the largest equity REITs in the country. The transaction also
marked the combination with the Company of respected names in the real estate
business, most notably William L. Mack and Mitchell E. Hersh. In connection with
the Mack Transaction, Mr. Mack and Mr. Hersh were appointed to the Board of
Directors of the Company. Mr. Mack also serves as Chairman of the Executive
Committee of the Board of Directors, and Mr. Hersh also serves as President and
Chief Operating Officer of the Company. In connection with the Mack Transaction,
Thomas A. Rizk resigned as President of the Company, but


                                       3
<PAGE>

remains as Chief Executive Officer and as a Director of the Company. See
"Recent Developments -- Mack Transaction" for a more detailed description of the
Mack Transaction. With the completion of the Mack Transaction, the Company
changed its name from "Cali Realty Corporation" to "Mack-Cali Realty
Corporation" and its operating partnership changed its name from "Cali Realty,
L.P." to "Mack-Cali Realty, L.P."

As of March 10, 1998, executive officers and directors of the Company and other
former owners of interests in certain of the Properties (many of whom are
employees of the Company) owned approximately 20.1 percent of the Company's
outstanding shares of Common Stock (including Units redeemable or convertible
for shares of Common Stock). As used herein, the term "Units" refers to limited
partnership interests in Mack-Cali Realty, L.P., a Delaware limited partnership
(the "Operating Partnership"), through which the Company conducts its real
estate activities.

The Company performs substantially all construction, leasing, management and
tenant improvements on an "in-house" basis and is self-administered and
self-managed.

The Company was incorporated on May 24, 1994. The Company's executive offices
are located at 11 Commerce Drive, Cranford, New Jersey 07016, and its telephone
number is (908) 272-8000. The Company has an internet Web address at
"http://www.mack-cali.com".

GROWTH STRATEGIES

The Company's objectives are to maximize growth in funds from operations (as
defined in Item 6 below) and to enhance the value of its portfolio through
effective management, acquisition and development strategies. The Company
believes that opportunities exist to increase cash flow per share by: (i)
implementing operating strategies to produce increased effective rental and
occupancy rates and decreased concession and tenant installation costs as
vacancy rates in the Company's sub-markets continue to decline; (ii) acquiring
properties with attractive returns in sub-markets where, based on its expertise
in leasing, managing and operating properties, it is, or can become, a
significant and preferred owner and operator; and (iii) developing properties
where such development will result in a favorable risk-adjusted return on
investment.

Based on its evaluation of current market conditions, the Company believes that
a number of factors will enable it to achieve its business objectives,
including: (i) the limited availability to competitors of capital for financing
development, acquisitions or capital improvements or for refinancing maturing
mortgages; (ii) the lack of new construction in the Company's primary markets
providing the Company with the opportunity to maximize occupancy levels at
attractive rental rates; and (iii) the large number of distressed sellers and
inadvertent owners (through foreclosure or otherwise) of office properties in
the Company's primary markets creating enhanced acquisition opportunities.
Management believes that the Company is well positioned to exploit existing
opportunities because of its extensive experience in its markets and its proven
ability to acquire, develop, lease and efficiently manage office properties.

The Company focuses on enhancing growth in cash flow per share by: (i)
maximizing cash flow from the existing Properties through continued active
leasing and property management; (ii) managing operating expenses through the
use of in-house management, leasing, marketing, financing, accounting, legal,
construction, management and data processing functions; (iii) emphasizing
programs of repairs and capital improvements to enhance the Properties'
competitive advantages in their markets; (iv) maintaining and developing
long-term relationships with a diverse tenant group; and (v) attracting and
retaining motivated employees by providing financial and other incentives to
meet the Company's operating and financial goals.

The Company will seek to increase its cash flow per share by acquiring
additional properties that: (i) provide attractive initial yields with
significant potential for growth in cash flow from property operations; (ii) are
well located, of high quality and competitive in their respective sub-markets;
(iii) are located in its existing sub-markets or in sub-markets which lack a
significant owner or operator; and (iv) have been under-managed or are otherwise
capable of improved performance through intensive management and leasing that
will result in increased occupancy and rental revenues.

Consistent with its acquisition strategy during 1997, the Company invested an
aggregate of approximately $1.8 billion in the Mack Transaction, the RM
Transaction and the acquisition of 13 other office and office/flex properties
(the "Individual Property Acquisitions"), thereby increasing its portfolio by
approximately 308 percent over year-end 1996 (based upon total net rentable
square feet). See "Business -- Recent Developments." There can be no assurance,
however, that the Company will be able to improve the operating performance of
any properties that are acquired.


                                       4
<PAGE>

The Company may also develop office and office/flex space on certain vacant land
acquired in connection with various acquisitions, or on which the Company holds
options, when market conditions support a favorable risk-adjusted return on such
development, primarily in stable submarkets where the demand for such space
exceeds available supply and where the Company is, or can become, a significant
owner and operator. The Company believes that opportunities exist for it to
acquire properties in the majority of its sub-markets at less than replacement
cost. Therefore, the Company currently intends to emphasize its acquisition
strategies over its development strategies until market conditions change. To
the extent that the costs associated with implementing such acquisition and
development strategies are financed using the Company's cash flow, such costs
may adversely affect the Company's ability to make distributions.

The Company currently intends to maintain a ratio of debt to total market
capitalization (total debt of the Company as a percentage of the market value of
issued and outstanding shares of Common Stock, including interests redeemable
therefor, plus total debt) of approximately 50 percent or less, although the
Company's organizational documents do not limit the amount of indebtedness that
the Company may incur. As of December 31, 1997, the Company's total debt
constituted approximately 27.8 percent of the total market capitalization of the
Company. The Company will utilize the most appropriate sources of capital for
future acquisitions, development and capital improvements, which may include
funds from operating activities, short-term and long-term borrowings (including
draws on the Company's revolving credit facilities) and issuances of debt
securities or additional equity securities.

EMPLOYEES

As of December 31, 1997, the Company had over 300 employees.

COMPETITION

The leasing of real estate is highly competitive. The Company's Properties
compete for tenants with lessors and developers of similar properties located in
its respective markets primarily on the basis of location, rent charged,
services provided, and the design and condition of property improvements. The
Company also experiences competition when attempting to acquire equity interests
in desirable real estate, including competition from domestic and foreign
financial institutions, other REIT's, life insurance companies, pension trusts,
trust funds, partnerships and individual investors.

REGULATIONS

Many laws and governmental regulations are applicable to the Properties and
changes in these laws and regulations, or their interpretation by agencies and
the courts, occur frequently.

Under various laws and regulations relating to the protection of the
environment, an owner of real estate may be held liable for the costs of removal
or remediation of certain hazardous or toxic substances located on or in the
property. These laws often impose liability without regard to whether the owner
was responsible for, or even knew of, the presence of such substances. The
presence of such substances may adversely affect the owner's ability to rent or
sell the property or to borrow using such property as collateral and may expose
it to liability resulting from any release of, or exposure to, such substances.
Persons who arrange for the disposal or treatment of hazardous or toxic
substances at another location may also be liable for the costs of removal or
remediation of such substances at the disposal or treatment facility, whether or
not such facility is owned or operated by such person. Certain environmental
laws impose liability for release of asbestos-containing materials into the air,
and third parties may also seek recovery from owners or operators of real
properties for personal injury associated with asbestos-containing materials and
other hazardous or toxic substances. In connection with the ownership (direct or
indirect), operation, management and development of real properties, the Company
may be considered an owner or operator of such properties or as having arranged
for the disposal or treatment of hazardous or toxic substances and, therefore,
potentially liable for removal or remediation costs, as well as certain other
related costs, including governmental penalties and injuries to persons and
property.

The Company obtained Phase I Assessments of each of its original properties (the
"Initial Properties") at the time of its initial public offering in August 1994
(the "IPO"). With the acquisition of each new property, the Company obtains a
Phase I Assessment for such property. These Phase I Assessments have not
revealed any environmental liability that the Company believes would have a
material adverse effect on the Company's business, assets or results of
operations taken as a whole, nor is the Company aware of any such material
environmental liability. 


                                       5
<PAGE>

In connection with the RM Transaction, the Company's environmental consultant
undertook environmental audits of the properties, including sampling activities,
which identified certain environmental conditions at several of the properties
(the "Designated Properties") that will likely require further investigation
and/or remedial activities. RM retained the liability and responsibility for
remediation of the environmental conditions of the Designated Properties, and
established an escrow in the amount of $1.5 million (the "Environmental Escrow")
as a clean-up fund. It is possible that the Company's assessments do not reveal
all environmental liabilities and that there are material environmental
liabilities of which the Company is unaware. Any remediation costs for the
Designated Properties exceeding the Environmental Escrow will remain the
responsibility of RM, with RM retaining the right to repurchase some or all of
the Designated Properties under certain conditions, including if the costs of
remediation of such property exceeds either its allocated property value or the
Environmental Escrow. See "Business -- Recent Developments -- RM Transaction."

There can be no assurance that (i) future laws, ordinances or regulations will
not impose any material environmental liability, (ii) the current environmental
condition of the Properties will not be affected by tenants, by the condition of
land or operations in the vicinity of the Properties (such as the presence of
underground storage tanks), or by third parties unrelated to the Company or
(iii) the Company's assessments reveal all environmental liabilities and that
there are no material environmental liabilities of which the Company is unaware.
If compliance with the various laws and regulations, now existing or hereafter
adopted, exceeds the Company's budgets for such items, the Company's ability to
make expected distributions to stockholders could be adversely affected.

There are no other laws or regulations which have a material effect on the
Company's operations, other than typical federal, state and local laws affecting
the development and operation of real property, such as zoning laws.

INDUSTRY SEGMENTS

The Company operates in only one industry segment-real estate. The Company does
not have any foreign operations and its business is not seasonal.

RECENT DEVELOPMENTS

During 1997, the Company completed the RM Transaction, the Mack Transaction and
the Individual Property Acquisitions, and has improved the operating performance
of its existing portfolio by maintaining high occupancies and controlling costs.
The Company's funds from operations (after adjustment for the straight-lining of
rents) for the year ended December 31, 1997 was $111.8 million. As a result of
the Company's improved operating performance and expanded equity capital base
through equity offerings of its Common Stock, in September 1997 the Company
announced an 11.1 percent increase in its regular quarterly distribution,
commencing with the Company's distribution with respect to the third quarter of
1997, from $0.45 per share of Common Stock ($1.80 per share of Common Stock on
an annualized basis) to $0.50 per share of Common Stock ($2.00 per share of
Common Stock on an annualized basis). Since 1995, the Company has increased its
regular quarterly distribution by 23.8 percent.

During 1997, the Company invested approximately $1.8 billion in the purchase of
the RM Transaction, the Mack Transaction and the Individual Property
Acquisitions, increasing its portfolio by approximately 308 percent (based upon
total net rentable square feet). The cash portions of the purchase prices for
such transactions and acquisitions (as more fully described below) were obtained
by the Company from (i) the net proceeds of the Company's public offering of
Common Stock in October 1997 for net proceeds of approximately $489.1 million,
(ii) borrowings under the Company's revolving credit facilities and from the
$200.0 million Prudential Term Loan (as hereinafter defined), and (iii)
available working capital. Furthermore, approximately $348.3 million in Units
were issued in connection with the RM Transaction, the Mack Transaction and one
of the Individual Property Acquisitions. In addition, a portion of each of the
purchase prices for the RM Transaction and the Mack Transaction included the
assumption of mortgage indebtedness ($185.3 million for the RM Transaction and
$291.9 million for the Mack Transaction). See "Business -- Financing
Activities." Set forth below are summary descriptions of the RM Transaction, the
Mack Transaction and the Individual Property Acquisitions:


                                       6
<PAGE>

RM Transaction

On January 31, 1997, the Company acquired the RM Properties for a total cost of
approximately $450.0 million. The RM Properties consist of 16 office properties,
38 office/flex properties, six industrial/warehouse properties, two stand-alone
retail properties, two land leases, and a multi-family residential property. The
RM Transaction was financed through the assumption of a $185.3 million mortgage,
approximately $220.0 million in cash, substantially all of which was obtained
from the Company's cash reserves, and the issuance of 1,401,225 Units, valued at
approximately $43.8 million.

In connection with the RM Transaction, the Company assumed a $185.3 million
non-recourse mortgage with Teachers Insurance and Annuity Association of
America, with interest only payable monthly at a fixed annual rate of 7.18
percent (the "TIAA Mortgage"). The TIAA Mortgage is secured and
cross-collateralized by 43 of the RM Properties and matures on December 31,
2003. The Company, at its option, may convert the TIAA Mortgage to unsecured
debt upon achievement by the Company of an investment credit rating of Baa3/BBB-
or better. The TIAA Mortgage is prepayable in whole or in part subject to
certain provisions, including yield maintenance.

The RM Properties, which consist primarily of 54 office and office/flex
properties aggregating approximately 3.7 million square feet and six
industrial/warehouse properties aggregating approximately 387,000 square feet,
are located primarily in established business parks in Westchester County, New
York and Fairfield County, Connecticut. The Company has agreed not to sell
certain of the RM Properties for a period of seven years without the consent of
the RM principals, except for sales made under certain circumstance and/or
conditions.

In connection with the RM Transaction, the Company was granted a three-year
option to acquire two properties (the "Option Properties") under certain
conditions, one of which was acquired in 1997. See "Recent Developments --
Individual Property Acquisitions." The purchase price for the remaining Option
Property is subject to adjustment based upon different formulas and is payable
in cash or common units.

In connection with the RM Transaction, the Company holds a $7.3 million
non-recourse mortgage loan ("Mortgage Note Receivable") with entities controlled
by the RM principals, bearing interest at an annual rate of 450 basis points
over the one-month London Inter-Bank Offered Rate (LIBOR). The Mortgage Note
Receivable, which is secured by the remaining Option Property and guaranteed by
certain of the RM principals, matures on February 1, 2000.

In conjunction with the completion of the RM Transaction, Robert F. Weinberg and
Brad W. Berger, son of Martin S. Berger, co-founder of RM with Mr. Weinberg,
were appointed to the Company's Board of Directors for an initial term of three
years. Mr. Berger subsequently resigned from the Board of Directors in December
1997 as a result of the Mack Transaction.

Mack Transaction

On December 11, 1997, the Company acquired the Mack Properties from The Mack
Company and Patriot American Office Group, pursuant to a Contribution and
Exchange Agreement (the "Agreement"), for a total cost of approximately $1.1
billion.

The Mack Properties consist of 54 office properties comprising a total of
approximately 9.2 million net rentable square feet, ranging from approximately
40,000 to 475,100 square feet. The Mack Properties are located primarily in the
Northeast and Southwest, with a concentration of properties located in Northern
New Jersey (25 properties compromising approximately 4.8 million square feet),
Texas (17 properties comprising approximately 2.5 million square feet) and
Arizona (four properties comprising approximately 485,000 square feet).

The total cost of the Mack Transaction was financed as follows: (i)
approximately $498.8 million in cash made available from the Company's cash
reserves and from the $200.0 million term loan from Prudential Securities Credit
Corp. (the "Prudential Term Loan"), (ii) approximately $291.9 million in
mortgage debt assumed by the Company (the "Mack Mortgages"), (iii) the issuance
of 1,965,886 common Units, valued at approximately $66.4 million, (iv) the
issuance of 15,237 Series A preferred units and 215,325 Series B preferred
units, valued at approximately $236.5 million (collectively, the "Preferred
Units"), (v) warrants to purchase 2,000,000 common units (the "Unit Warrants"),

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 performance goals relating to certain of the Mack Properties,
specifically the achievement of certain leasing activity.

With the Mack Transaction, the Company assumed an aggregate of approximately
$291.9 million of mortgage indebtedness with eight separate lenders, encumbering
17 of the Mack Properties. Such debt matures at various dates from March 1998
through January 2009. The Mack Mortgages are comprised of an aggregate of
approximately $199.9 million of fixed rate debt bearing interest at a weighted
average rate of approximately 7.66 percent per annum, certain of which require
monthly principal amortization payments, and an aggregate of approximately $91.9
million in variable rate debt bearing interest at a weighted average floating
rate of approximately 76 basis points over LIBOR.

With the completion of the Mack Transaction, the "Cali Realty Corporation" name
was changed to "Mack-Cali Realty Corporation", and the name of the Operating
Partnership was changed from "Cali Realty, L.P." to "Mack-Cali Realty, L.P."

In connection with the Mack Transaction, Brant Cali, Brad W. Berger, Angelo R.
Cali, Kenneth A. DeGhetto, James W. Hughes and Alan Turtletaub resigned from the
Board of Directors of the Company. Mitchell E. Hersh, William L. Mack and Earle
I. Mack were added to the Board as "inside" members, and Martin D. Gruss,

the business dealings of such individuals relative to their involvement in
commercial real estate activities to those specified in the Agreement. The
non-competition agreements have a term of the later of (a) three years from the
completion of the Mack Transaction, or (b) the occurrence of specified
circumstances including, but not limited to, the removal of William, Earle,
David or Fredric Mack, respectively, from the Company's Board of Directors or
Advisory Board, as applicable, and a decrease in certain ownership levels.

In connection with the Mack Transaction, under each of the Company's executive
officer's then existing employment agreements (dated January 21, 1997), due to a
change of control of the Company (as defined in each employment agreement), each

the immediate vesting and issuance of his restricted stock, including tax
gross-up payments associated therewith, (ii) the forgiveness of his Stock
Purchase Rights loan, including tax gross-up payments associated therewith, and
(iii) the vesting of his unvested employee stock options and warrants.
Additionally, under each of Thomas Rizk's, Brant Cali's and John R. Cali's
employment agreements with the Company, each of these officers became entitled
to receive certain severance-type payments, as a result of certain provisions in
each of their agreements, triggered as result of the Mack Transaction. Finally,
certain officers and employees of the Company were given transaction-based
payments as a reward for their efforts and performance in connection with the
Mack Transaction. The total expense associated with the acceleration of vesting
of restricted stock, the forgiveness of Stock Purchase Rights loans, and the
payment of certain severance-type payments as well as performance payments, and
related tax-obligation payments, which were approved by the Company's Board of
Directors and which took place simultaneous with completion of the Mack
Transaction, totaled $45.8 million.

FINANCING ACTIVITIES

The Company utilizes the most appropriate sources of capital for acquisitions,
development, joint ventures and capital improvements, which sources may include
undistributed funds from operations, borrowings under its revolving credit
facilities, issuances of debt or equity securities and/or bank and other
institutional borrowings.

Revolving Credit Facilities and Other Indebtedness
As of December 31, 1997, the Company's two revolving credit facilities consisted
of the Unsecured Facility and the Prudential Facility (each described below)
with an aggregate borrowing capacity of $500.0 million and an aggregate
outstanding balance of $122.1 million.

The Company has a revolving credit facility ("Prudential Facility") from
Prudential Securities Credit Corp. ("PSC"), an affiliate of Prudential
Securities Incorporated, in the amount of $100.0 million, which currently bears
interest at 110 basis points over one-month LIBOR, and matures on March 31,
1999. The Prudential Facility is a recourse liability of the Operating
Partnership and is secured by the Company's equity interest in its property
known as the Harborside Financial Center ("Harborside"). The terms of the
Prudential Facility include certain restrictions and covenants that limit, among
other things, dividend payments and additional indebtedness and that require
compliance with specified financial ratios and other financial measurements.


                                       10
<PAGE>

In August 1997, the Company obtained an unsecured revolving credit facility (the
"Unsecured Facility") in the amount of $400.0 million from a group of 13 lender
banks. The unsecured Facility has a three year term and currently bears interest
at 125 basis points over one-month LIBOR. Based upon the Company's achievement
of an investment grade long-term unsecured debt rating, the interest rate will
be reduced, on a sliding scale, and a competitive bid option will become
available. The lending group for the Unsecured Facility includes: Fleet National
Bank, The Chase Manhattan Bank, and Bankers Trust Company, as agents; PNC Bank,
N.A., Bank of America National Trust and Savings Association, Commerzbank AG,
and First National Bank of Chicago, as co-agents; and Keybank, Summit Bank,
Crestar Bank, Mellon Bank, N.A., Signet Bank, and KredietBank NV.

The terms of the Unsecured Facility include certain restrictions and covenants
which limit, among other things, dividend payments and additional indebtedness
and which require compliance with specified financial ratios and other financial
measurements. The Unsecured Facility also requires a fee on the unused balance
payable quarterly in arrears, at a rate ranging from one-eighth of one percent
to one-quarter of one percent of such balance, depending on the level of
borrowings outstanding in relation to the total facility commitment.

Concurrently with the closing of the Unsecured Facility, the Company drew funds
on such facility to repay in full and terminate two of the Company's existing
secured revolving credit facilities and to repay in full the then outstanding
balance under its Prudential Facility. In addition, in August 1997, the Company
retired its remaining $64.5 million real estate mortgage investment conduit
(REMIC) secured financing primarily from funds drawn on the Unsecured Facility.

On December 10, 1997, the Company obtained the Prudential Term Loan in the
amount of $200.0 million from PSC. The proceeds of the loan were used to fund a
portion of the cash consideration in completion of the Mack Transaction. The
loan has a one-year term and bears interest at 110 basis points over one-month
LIBOR.

Contingent Obligation

As part of the Harborside acquisition in 1996, the Company agreed to make
payments (with an estimated net present value of approximately $5.7 million at
December 31, 1997) 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.

Permanent Indebtedness

As of December 31, 1997, the Company had outstanding an aggregate balance of
approximately $644.8 million of long-term mortgage indebtedness (excluding
borrowings under the Company's revolving credit facilities and other
indebtedness described above).

In connection with the acquisition of an office building in Fair Lawn, Bergen
County, New Jersey on March 3, 1995, the Company assumed an $18.8 million
non-recourse mortgage loan ("Fair Lawn Mortgage") bearing interest at a fixed
rate of 8.25 percent per annum. The loan currently requires payment of principal
and interest on a 20-year amortization schedule, with the remaining principal
balance due October 1, 2003. At December 31, 1997, the principal balance for the
Fair Lawn Mortgage was approximately $18.0 million.

In connection with the acquisition of Harborside, on November 4, 1996, the
Company assumed existing mortgage debt and was provided seller-financed mortgage
debt aggregating $150.0 million. The existing financing, with a principal
balance of approximately $104.8 million as of December 31, 1997, bears interest
at a fixed rate of 7.32 percent per annum for a term of approximately nine
years. The seller-provided financing, with a principal balance of approximately
$45.2 million as of December 31, 1997, also has a term of approximately nine
years and initially bears interest at a rate of 6.99 percent per annum. The
interest rate on the seller-provided financing will be reset at the end of the
third and sixth loan years based on the yield of the three-year treasury
obligation at that time, with spreads of 110 basis points in years four through
six and 130 basis points in years seven through maturity.

In connection with the RM Transaction on January 31, 1997, the Company assumed a
$185.3 million non-recourse mortgage loan with Teachers Insurance and Annuity
Association of America, with interest only payable monthly at a fixed annual
rate of 7.18 percent. The TIAA Mortgage is secured and cross-collateralized by
43 of the RM Properties and matures on December 31, 2003. The Company, at its
option, may convert the TIAA Mortgage to unsecured public


                                       11
<PAGE>

debt upon achievement by the Company of an investment credit rating of Baa3/BBB-
or better. The TIAA Mortgage is prepayable in whole or in part subject to
certain provisions, including yield maintenance.

In connection with the Mack Transaction on December 11, 1997, the Company
assumed an aggregate of approximately $291.9 million of mortgage indebtedness
with eight separate lenders, encumbering 17 of the Mack Properties. Such debt
matures at various dates from March 1998 through January 2009. The Mack
Mortgages are comprised of an aggregate of approximately $199.9 million of fixed
rate debt bearing interest at a weighted average rate of approximately 7.66
percent per annum, certain of which require monthly principal amortization
payments, and an aggregate of approximately $91.9 million in variable rate debt
bearing interest at a weighted average floating rate of approximately 76 basis
points over LIBOR. At December 31, 1997, the aggregate principal balances for
the Mack Mortgages was approximately $291.5 million.

Interest Rate Contracts:
The Company has 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 through August 1999.

The Company has another interest rate swap agreement with a commercial bank.
This swap agreement has a three-year term and a notional amount of $26.0
million, which fixes the Company's one-month LIBOR base to 5.265 percent per

On November 20, 1997, the Company entered into a seven-year, interpolated U.S.
Treasury interest rate lock agreement with a commercial bank. The agreement

anticipate non-performance by any of its counterparties.

three-year term and will bear interest at 110 basis points over LIBOR.

Equity Offerings and Shelf Registration Statements:
On October 15, 1997, the Company completed an underwritten public offer and sale
of 13,000,000 shares of its Common Stock using several different Underwriters to
underwrite such public offer and sale. The shares were issued from the Company's
$1.0 billion shelf registration statement (declared effective on January 7,

(1)   Based on all leases in effect as of December 31, 1997.

(2)   Total base rent for 1997, determined in accordance with generally accepted
      accounting principles (GAAP). 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.

(3)   Total base rent for 1997 minus total 1997 amortization of tenant
      improvements, leasing commissions and other concessions and costs,
      determined in accordance with GAAP.

(4)   Base rent for 1997 divided by net rentable square feet leased at December
      31, 1997. For those Properties acquired by the Company during 1997,
      amounts presented are annualized, as per Note 7.

(5)   Effective rent for 1997 divided by net rentable square feet leased at
      December 31, 1997. For those Properties acquired by the Company during
      1997, amounts presented are annualized, as per Note 7.

(6)   Excludes office space leased by the Company.

(7)   As this Property was acquired by the Company during 1997, the amounts
      represented in 1997 base rent and 1997 effective rent reflect only that
      portion of the year during which the Company owned or placed the Property
      in service. Accordingly, these amounts may not be indicative of the
      Property's full year results. For comparison purposes, the amounts
      represented in 1997 average base rent per sq. ft. and 1997 average
      effective rent per sq. ft. for this Property have been calculated by
      taking 1997 base rent and 1997 effective rent for such Property and
      annualizing these partial-year results, dividing such annualized amounts
      by the net rentable square feet leased at December 31, 1997. These
      annualized per square foot amounts may not be indicative of the Property's
      results had the Company owned or placed such Property in service for the
      entirety of 1997.

Harborside Financial Center, Jersey City, Hudson County, New Jersey

As the book value of Harborside was in excess of 10 percent of the Company's
total assets at December 31, 1997, additional information regarding the Property
is provided below.

Harborside, acquired by the Company on November 4, 1996, is a completely
redeveloped, three-building office complex containing 1,886,800 square feet of
net rentable area located in the Exchange Place Newport Center submarket of
Jersey City, New Jersey. This submarket is a satellite office market of
Manhattan and is occupied primarily by the support and technical operations of
New York City-based financial institutions. The buildings, known as Plazas I, II
and III, were developed as a complete reconstruction of existing buildings in
two phases, with the first completed in 1983 and the second in 1990. The
buildings are connected via an enclosed 1,000 foot waterfront promenade
featuring restaurants, service retail shops and a food court, as well as an
atrium lobby. The promenade includes various retail operations such as
restaurants, a bank, and a dry cleaner. The property is situated on 47.98 acres
for the existing building complex, 11.29 acres of undeveloped land, 5.78 acres
of piers and 21.61 acres of underwater land (excluding piers).

Plaza I is served by six passenger elevators as well as a 15,000 lb. freight
car. Plazas II and III are each served by ten passenger elevators and have seven
oversized freight elevators in total. In addition, there are large shafts where
freight elevators have been removed which enable tenants to bring significant
electric telecommunications cabling to their space at minimal cost.

The property leases space to parking operators and provides for approximately
1,685 parking spaces including 200 spaces on the south pier. Public
transportation to the property is available through the Exchange Place PATH rail
station which is immediately adjacent to the property and links Harborside to
downtown Manhattan in approximately four minutes. The PATH also provides access
to midtown Manhattan, Newark and Hoboken in less than twenty minutes. The
property is also connected to Manhattan by road via a three mile drive to the
Holland Tunnel and a five-mile drive to the Lincoln Tunnel. Interstates 78 and
495, U.S. Routes 1, 9 and 440, and NJ Route 3 connect the property to locations
throughout northern New Jersey.

Bankers Trust Harborside, Inc., a commercial bank, occupied 385,000 square feet

December 31, 1997, pursuant to a triple-net lease which expires March 31, 2003,
with a five-year renewal option. Total rental income from Bankers Trust,

life of the real property which range from 15 to 39 years. There is no
depreciable personal property associated with Harborside for federal income tax

assumed by the Company as part of the acquisition of Harborside on November 4,
1996. The abatements, which commenced in 1990, are for a term of 15 years. The

THE COMPANY'S REAL ESTATE MARKETS

The Company's Properties are located primarily in the Northeast and Southwest,
including a predominant presence in New Jersey, New York, Pennsylvania, Texas
and Arizona. The following is a discussion of the markets within which
substantially all of the Company's properties are located:

Northern New Jersey: The Northern New Jersey market consists of Bergen, Essex,
Hudson, Morris and Passaic Counties. Northern New Jersey's five counties are
part of the greater New York metropolitan area, are less than a 45 minute drive
from Manhattan, and are widely regarded as major centers for corporate and
international business. The region has direct access to New York City by public
transportation and extensive road networks. In addition to being home to the two
largest cities in New Jersey, Newark and Jersey City, Newark International
Airport and the New York/New Jersey Harbor are also located within the
five-county boundary.

Overall vacancy rates have declined in the Northern New Jersey market for the
fifth consecutive year as a direct result of an increase in leasing activity and
net absorption levels. Although some built-to-suit activity is present,
speculative construction remains virtually nonexistent. The Company owns and
operates approximately 8.6 million square feet of office and office/flex space
in Northern New Jersey.

Central New Jersey: The Central New Jersey market consists of Union, Somerset,
Hunterdon, Middlesex, Mercer and Monmouth Counties. Encompassing approximately
2,000 square miles in six counties, Central New Jersey is notable for its
proximity to major highway arteries, including Interstates 78 and 287, Route 1,
the Garden State Parkway and the New Jersey Turnpike. This market continues to
be a prime location for Fortune 500 headquarters, research & development
operations and financial, insurance and real estate (FIRE) sector businesses.

Central New Jersey vacancy rates are decreasing while average asking rents are
increasing. This is, in part, attributable to the increase in demand, measured
by leasing activity, which rose predominantly due to corporate expansions. The
Company owns and operates approximately 2.6 million square feet of office and
office/flex space in the Central New Jersey counties of Union, Mercer and
Monmouth.

Suburban Philadelphia, Pennsylvania: The Suburban Philadelphia market consists
of six counties in Pennsylvania on the west side of the Delaware River and eight
counties in New Jersey on the east side of the Delaware River. The Pennsylvania
counties consist of Bucks, Chester, Delaware, Montgomery, Lehigh and Northampton
Counties. These six counties surround the City of Philadelphia, are home to many
affluent communities, and are regarded as major centers for corporate and
international business. The areas are served by an extensive highway network
allowing easy access to Philadelphia International Airport and the Port of
Philadelphia.

Over the last few years the overall vacancy rate in this region has declined and
in 1996, the rate dipped below 10 percent for the first time as a result of
strong leasing activity and virtually no new construction. The Company owns and
operates approximately 1.5 million square feet of office space in these Suburban
Philadelphia counties.


                                       42
<PAGE>

The New Jersey counties consist of Burlington, Camden, Atlantic, Ocean,
Gloucester, Salem, Cumberland and Cape May Counties. This market has extensive
geographic boundaries, stretching from the Delaware River to the Atlantic Ocean
and Atlantic City. This region is mainly suburban, with the exception of Camden
County, which is home to many affluent communities, and Atlantic City, one of
the nation's largest centers for gaming/tourism.

The Company owns and operates approximately 228,300 square feet of office space
and one 327-unit multi-family residential complex in Atlantic and Burlington
Counties.

Rockland County, New York: Rockland County, New York is located north of the New
Jersey/New York border directly adjacent to Bergen County. Rockland County has
excellent highway access to both New York City via Interstate 87 and to New
Jersey via Interstate 287.

The Company owns and operates a 180,000 square foot office property in Rockland
County.

Westchester County, New York: Westchester County, New York, is located
immediately north of New York City and is accessible to New York City by public
transportation and through an extensive road network. In Westchester County, the
vacancy rate has declined steadily over the last three years as the office
market has absorbed 3 million square feet that IBM, AT&T and NYNEX vacated from
1989 to 1993. Speculative construction has been virtually non-existent during
the past five years.

The Company owns and operates approximately 3.6 million square feet of office
and office/flex space, 387,400 square feet of industrial/warehouse space, a
126-unit multi-family residential property, two stand-alone retail properties,
and two land leases in Westchester County, New York. The Company entered this
market for the first time with the RM Transaction.

Fairfield County, Connecticut: Fairfield County, Connecticut is the county in
Connecticut closest in proximity with New York City. It has direct access to New
York City via public transportation and through an extensive road network. The
county is home to ten Fortune 500 headquarters and there has been a substantial
decline in vacancy during the past two years.

The Company owns and operates approximately 300,000 square feet of office and
office/flex space in Fairfield County. The Company entered this market for the
first time with the RM Transaction.

Dallas-Fort Worth, Texas: The Dallas-Fort Worth market includes Dallas, Tarrant
and portions of Collin and Denton Counties. The market includes the central
business districts of both Dallas and Fort Worth and the suburban areas
primarily to the north of those cities. Dallas-Forth Worth International Airport
is one of the busiest airports in the nation and is important to the growth of
the area. This area is home to the headquarters of numerous Fortune 500
companies. The Company entered this market for the first time with the Mack
Transaction, and owns and operates approximately 1.0 million square feet of
office space in Dallas, Tarrant and Collin Counties.

Houston, Texas: The Houston office market is comprised primarily of the city of
Houston and its surrounding suburbs. Houston is a major location of Fortune 500
companies' headquarters, primarily in the oil and gas industries. Houston is
also a major port serving the southern portion of the United States. The Company
entered this market for the first time with the Mack Transaction, and owns and
operates approximately 700,000 square-feet in the Houston market.

San Antonio, Texas: The San Antonio market consists primarily of Bexar County.
San Antonio is located at the cross roads of two major arteries, Interstate 35
and Interstate 10, and is a primary location of military facilities. San Antonio
is the third largest metropolitan area in Texas, behind Dallas and Houston. The
Company entered this market for the first time with the Mack Transaction, and
owns approximately 940,000 square feet of office space in Bexar County.

Phoenix, Arizona: The Phoenix market is comprised primarily of the city of
Phoenix and several suburbs to the north and west, including Scottsdale. Phoenix
is the focal point of Arizona, in addition to being the state capital. It is the
location of numerous corporate headquarters and regional headquarter facilities.
The Phoenix market has been considered one of the most rapidly growing markets
in the county. The Company entered this market for the first time with the Mack
Transaction, and owns and operates approximately 484,670 square feet of office
space in the Phoenix market.

(2)   The Company considers funds from operations (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 (preferred and common) 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 for 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.

The following discussion should be read in conjunction with the Consolidated

      The following comparisons for the year ended December 31, 1997 ("1997"),
as compared to the year ended December 31, 1996 ("1996") and for 1996, as
compared to the year ended December 31, 1995 ("1995") make reference to the
following: (i) the effect of the "Same-Store Properties," which represent all
properties owned by the Company at December 31, 1995 (for the 1997 versus 1996
comparison), and which represents all properties owned by the Company at
December 31, 1994 (for the 1996 versus 1995 comparison), (ii) the effect of the
acquisition of the RM Properties on January 31, 1997 (iii) the effect of the
acquisition of the Mack Properties on December 11, 1997, (iv) the effect of the

the Mack Properties, (for the 1997 versus 1996 comparison), and which represent
all properties acquired by the Company from January 1, 1995 through December 31,
1996 (for the 1996 versus 1995 comparison), and (v) the effect of the
"Disposition," which refers to the Company's sale of its Essex Road property on
March 20, 1996.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

Total revenues increased $154.3 million, or 161.6 percent, for 1997 over 1996.
Base rents increased $129.3 million, or 168.1 percent, of which an increase of
$61.4 million, or 79.7 percent, was attributable to the Acquired Properties, an
increase of $58.4 million, or 75.9 percent, due to the RM Properties, an
increase of $8.0 million, or 10.4 percent, due to the Mack Properties and an
increase of $1.8 million, or 2.4 percent, due to occupancy and rental rate
changes at the Same-Store Properties, offset by a decrease of $0.3 million, or
0.3 percent, due to the Disposition. Escalations and recoveries increased $16.7
million, or 115.7 percent, of which an increase of $11.2 million, or 77.4
percent, was attributable to the Acquired Properties, an increase of $4.9
million, or 34.2 percent, due to the RM Properties, an increase of $0.5 million,
or 3.7 percent, due to the Mack Properties, and an increase of $0.1 million, or
0.4 percent, due to occupancy changes at the Same-Store Properties. Parking and
other income increased $4.7 million, or 213.5 percent, of which $4.0 million, or
182.1 percent, was attributable to the RM Properties and $0.8 million, or 37.6
percent, was attributable to the Acquired Properties, offset by a decrease of
$0.1 million, or 6.2 percent, due to the Same-Store Properties. Interest income
increased $3.6 million, or 189.3 percent, due primarily to investment of the
funds held from the Company's October 1997 common stock offering.

      Total expenses for 1997 increased $149.4 million, or 233.7 percent, as
compared to 1996. Real estate taxes increased $16.6 million, or 176.7 percent,

increase of $1.7 million, or 8.2 percent, due to the Mack Properties, offset by
a decrease of $1.1 million, or 5.3 percent, attributable to the Same-Store

increase in payroll and related costs as a result of the Company's expansion in
late 1996 and 1997 and $3.0 million, or 52.4 percent, is attributable to
additional costs related to the RM Properties. Depreciation and amortization

offset by a decrease of $0.1 million, or 0.5 percent, due to the Disposition.

$1.4 million, or 9.9 percent, due to assumed mortgages from the Mack Properties,
and an increase of $8.3 million, or 60.1 percent, due to net additional drawings
from the Company's credit facilities as a result of Company acquisitions and the
$200 million Prudential Term Loan obtained in December 1997, as well as changes
in LIBOR, offset by a decrease of $5.7 million, or 41.1 percent, due to the
August 1997 prepayment of the Mortgage Financing. Non-recurring merger-related
charges of $46.5 million were incurred in 1997, as a result of the Mack
Transaction.

MD&A

Mack-Cali Realty Corporation and Subsidiaries

      Income before gain on sale of rental property, minority interest, and
extraordinary items increased to $36.4 million in 1997 from $31.5 million in
1996. The increase of $4.9 million was due to the factors discussed above.

      Net income decreased $30.5 million for 1997, from $31.9 million in 1996 to
$1.4 million in 1997, primarily as a result of an increase in income allocable
to minority interests of $26.6 million, including the effect of the beneficial
conversion feature and distributions to preferred unitholders (See Note 13 to
Financial Statements). Net income was also effected by a gain on the sale of the
Disposition property of $5.7 million in 1996 and the recognition in 1997 of an
extraordinary loss of $3.6 million (net of minority interest's share of $0.4
million), offset by an increase in income before gain on sale of rental
property, minority interest and extraordinary item of $4.9 million, and the
recognition in 1996 of an extraordinary loss of $0.5 million (net of minority
interest's share of $0.1 million.)

million, or 51.8 percent, of which an increase of $4.6 million, or 49.0 percent,

million, or 4.3 percent, due to the Disposition. Interest income increased $1.6
million for 1996 over 1995, due primarily to the funds held at December 31, 1996
from the Company's common stock offering in November 1996.

      Total expenses for 1996 increased $18.7 million, or 41.5 percent, as
compared to 1995. Real estate taxes increased $3.5 million, or 60.4 percent, for
1996 over 1995, of which $3.6 million, or 60.9 percent, was a result of the
Acquired Properties, and $0.1 million, or 2.6 percent, related to the Same-Store
Properties, offset by a decrease of $0.2 million, or 3.1 percent, due to the
Disposition. Additionally, operating services increased $3.6 million, or 42.4
percent, and utilities increased $1.8 million, or 28.6 percent. The aggregate
increase in operating services and utilities of $5.4 million, or 36.5 percent,
consists of $5.9 million, or 39.9 percent, attributable to the Acquired
Properties, offset by a decrease of $0.5 million, or 3.4 percent, as a result of
the Disposition. General and administrative expense increased $2.1 million, or
56.3 percent, of which $2.2 million, or 57.5 percent, is primarily attributable
to an increase in payroll and related costs as a result of the Company's
expansion in 1996, offset by a decrease of $0.1 million, or 1.2 percent, due to
the Disposition. Depreciation and amortization increased $4.1 million, or 38.3
percent, for 1996 over 1995, of which $4.4 million, or 41.8 percent, related to
depreciation on the Acquired Properties, offset by decreases of $0.1 million, or
1.3 percent, for amortization of deferred financing costs due to reduction in
debt outstanding on the Same-Store Properties, and $0.2 million, or 2.2 percent,
as a result of the Disposition. Interest expense increased $3.6 million, or 36.0
percent, primarily due to an increase in the average outstanding borrowings on
the Company's credit facilities during 1996 over 1995 in connection with an
increase in property acquisitions, as well as the increase in mortgage
indebtedness assumed in connection with the acquisition of Harborside.

      Income before gain on sale of rental property, minority interest and
extraordinary item increased to $31.5 million in 1996 from $17.1 million in
1995. The increase of $14.4 million was due to the factors discussed above.

      Net income increased $18.3 million for 1996, from $13.6 million in 1995 to
$31.9 million in 1996, as a result of an increased in income before gain on sale
of property, minority interest and extraordinary item of $14.4 million and a
gain on sale of the Disposition property of $5.7 million, offset by the increase
in minority interest of $1.3 million and the recognition in 1996 of an
extraordinary loss for the early retirement of debt of $0.5 million (net of
minority interest's share of $0.1 million).

Liquidity and Capital Resources

Statement of Cash Flows

During the year ended December 31, 1997, the Company generated $98.1 million in
cash flows from operating activities, and together with $489.1 million in net
proceeds from the Company's 13 million share offering in October 1997, $469.2
million in borrowings from the Company's credit facilities, $202.1 million from
the Company's cash reserves, $200.0 million in proceeds from a short-term
mortgage loan, $7.2 million of proceeds from stock options exercised, and $1.1
million from restricted cash, used an aggregate of $1.47 billion to purchase 132


                                       51

properties and pay for other tenant improvements and building improvements for
$929.0 million, repay outstanding borrowings on its credit facilities and other
mortgage debt of $441.8 million, pay quarterly dividends and distributions of
$74.5 million, provide $11.6 million for a Mortgage Note Receivable, repurchase
152,000 shares of the Company's common stock for $4.7 million, pay financing
costs of $3.1 million, pay debt prepayment and other costs of $1.8 million and
pay the amortization on mortgage principal of $0.4 million.

Capitalization

On August 13, 1996 the Company sold 3,450,000 shares of its common stock through
a public stock offering (the "August 1996 Offering"). Net proceeds from the
August 1996 Offering (after offering costs) were approximately $76.8 million.

      On November 4, 1996, the Company obtained a revolving credit facility
("Second Prudential Facility") from PSC currently totaling $100 million which
bears interest at 110 basis points over one-month LIBOR, and matures on March
31, 1999. The Second Prudential Facility is a recourse liability of the
Operating Partnership and is secured by the Company's equity interest in
Harborside. The terms of the Second Prudential Facility include certain
restrictions and covenants that limit, among other things, dividend payments and
additional indebtedness and that require compliance with specified financial
ratios and other financial measurements.

      In addition, on November 4, 1996, the Company assumed existing debt and
was provided seller-financed mortgage debt aggregating $150 million in
connection with the Harborside acquisition (see Note 7 to the Financial
Statements).

      On November 22, 1996, the Company completed an underwritten public offer
and sale of 17,537,500 shares of its common stock using several different
underwriters to underwrite such public offer and sale (which included an
exercise of the underwriters' over-allotment option of 2,287,500 shares). The
Company received approximately $441.2 million in net proceeds (after offering
costs) from the offering, and used such funds to complete certain of the
Company's property acquisitions in November and December 1996, pay down
outstanding borrowings on its revolving credit facilities, and invest in
Overnight Investments.

      In connection with the RM Transaction on January 31, 1997, the Company
assumed a $185.3 million non-recourse mortgage loan with TIAA (see Note 7 to the
Financial Statements).

      From April 18, 1997 through April 24, 1997, the Company purchased, for
constructive retirement, 152,000 shares of its outstanding common stock for $4.7
million. Concurrent with this purchase, the Company sold to the Operating
Partnership 152,000 Common Units for $4.7 million.

      On May 15, 1997, the stockholders approved an increase in the authorized
shares of common stock in the Company from 95 million to 190 million.

      On August 6, 1997, the Company obtained an unsecured revolving credit
facility (the "Unsecured Facility") in the amount of $400 million from a group
of 13 lender banks. The Unsecured Facility has a three-year term and currently
bears interest at 125 basis points over one-month LIBOR. Based upon the
Company's achievement of an investment grade long-term unsecured debt rating,
the interest rate will be reduced, on a sliding scale, and a competitive bid
option will become available.

      The lending group for the Unsecured Facility consist of: Fleet National
Bank, The Chase Manhattan Bank, and Bankers Trust Company, as agents; PNC Bank,
N.A., Bank of America National Trust and Savings Association, Commerzbank AG,
and The First National Bank of Chicago, as co-agents; and KeyBank, Summit Bank,
Crestar Bank, Mellon Bank, N.A., Signet Bank, and KredietBank NV.

      In conjunction with the Company obtaining the Unsecured Facility, the
Company drew funds on the new facility to repay in full and terminate both the
First Prudential Facility and the Bank Facility. The Company drew an additional
$70 million to repay in full the outstanding balance under the Second Prudential
Facility.

      On August 12, 1997, the Company prepaid in full and retired the secured
Mortgage Financing from funds made available primarily from drawing on the
Unsecured Facility (see Note 7 to the Financial Statements).

      With the Mack Transaction on December 11, 1997, the Company assumed an
aggregate of approximately $291.9 million of mortgage indebtedness with eight
separate lenders, encumbering 17 of the Mack Properties (the "Mack Mortgages").
Such debt matures at various dates from March 1998 through January 2009. The
Mack Mortgages are comprised of an aggregate of approximately $199.9 million of
fixed rate debt bearing interest at a weighted average rate of approximately
7.66 percent per annum, certain of which require monthly principal amortization
payments, and an aggregate of approximately $92.0 million in variable rate debt
bearing interest at a weighted average floating rate of approximately 76 basis
points over LIBOR (see Note 7 to the Financial Statements).

      On December 10, 1997, the Company obtained a $200 million term loan from
PSC (the "Prudential Term Loans"). The proceeds of the loan were used to fund a
portion of the cash consideration in completion of the Mack Transaction. The
loan has a one-year term and interest payments are required monthly at an
interest rate of 110 basis points over one-month LIBOR. The loan is a recourse
loan secured by 11 properties owned by the Company and located in New Jersey.

MD&A

Mack-Cali Realty Corporation and Subsidiaries

      On October 15, 1997, the Company completed an underwritten public offer
and sale of 13,000,000 shares of its common stock (the "1997 Offering"), from
which the Company received approximately $489.1 million in net proceeds (after
offering costs). The Company used $160 million of such proceeds to repay
outstanding borrowings on its Unsecured Facility and the remainder of the
proceeds to fund a portion of the purchase price of the Mack Transaction, for
other acquisitions, and for general corporate purposes.

      On February 25, 1998, the Company completed an underwritten public offer
and sale of 2,500,000 shares of its common stock using one underwriter. The
Company used the net proceeds, which totaled approximately $92.0 million (after
offering costs) to make a partial paydown of outstanding borrowings under the
Unsecured Facility and to fund the acquisition of Mountainview.

      Following the February 1998 stock offering, the Company has approximately
$2.4 billion in availability under its effective equity shelf registrations.

      As of December 31, 1997, the Company had 114 unencumbered properties,
totaling 11.3 million square feet, representing approximately 51.2 percent of
the Company's year-end portfolio.

      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 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 Second Prudential Facility and the Unsecured
Facility. The Company is frequently examining potential property acquisitions
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 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 credit
facilities) and the issuance of debt securities or additional equity securities.
In addition, the Company anticipates utilizing the Second Prudential Facility
and the Unsecured Facility primarily to fund property acquisition activities.

      The Company does not intend to reserve funds to retire the existing TIAA
Mortgage, Harborside Mortgages, Mack Mortgages, and borrowings under the
revolving credit facilities 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 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
distribution discussed below may be adversely affected.

      To maintain its qualification as a REIT, the Company must make annual
dividend payments 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 dividend payments to its stockholders which, based upon
current policy, in the aggregate would equal approximately $104.9 million on an
annualized basis, as well as quarterly distributions to unitholders. However,
any such dividend or 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, (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 (preferred and common), 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.

Inflation

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

Disclosure Regarding Forward-Looking Statements

The Company considers portions of this information to be forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of The Securities Exchange Act of 1934. 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.

Report of Independent Accountants

To the Board of Directors and
Shareholders of Mack-Cali Realty Corporation

In our opinion, the consolidated financial statements listed in the index
appearing in Item 14 (a) (1) and (2) present fairly, in all material respects,
the financial position of Mack-Cali Realty Corporation and its subsidiaries at
December 31, 1997 and 1996, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

Notes to Consolidated Financial Statements 
Mack-Cali Realty Corporation and Subsidiaries 
(dollars in thousands, except per share or unit amounts)

1) Organization and Basis of Presentation

Organization

Mack-Cali Realty Corporation, (previously 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 December 31, 1997, the Company owned and
operated 189 properties (the "Properties") aggregating approximately 22.0
million square feet, consisting of 177 office and office/flex buildings totaling
approximately 21.6 million square feet, six industrial/warehouse buildings
totaling approximately 387,000 square feet, two multi-family residential
complexes consisting of 453 units, two stand-alone retail properties and two
land leases. The Properties are located in ten states, primarily in the
Northeast and Southwest.

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"). 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.

      Depreciation and amortization is computed on a straight-line basis over
the estimated useful lives of the assets as follows:

- --------------------------------------------------------------------------------
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. Management does not believe that
the value of any of its rental properties is impaired.

Cash and Cash Equivalents - All highly liquid investments with a maturity of
three months or less when purchased are considered to be cash equivalents. At
December 31, 1996, cash and cash equivalents included investments in overnight
reverse repurchase agreements ("Overnight Investments") totaling $201,269.
Investments in Overnight Investments are subject to the risks that the
counter-party will default and the collateral will decline in market value. The
Overnight Investments held by the Company at December 31, 1996 matured on
January 2, 1997. The entire balance, including interest income earned, was
realized by the Company and ultimately used in the funding of the RM Transaction
on January 31, 1997 (see Note 3).

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 $983, $1,081 and $1,456 for the
years ended December 31, 1997, 1996 and 1995, 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 are 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 fees as compensation ranging from 0.667 percent to
2.667 percent of adjusted rents. For the years ended December 31, 1997, 1996 and
1995, such fees, which are capitalized and amortized, approximated $761, $490
and $575, respectively.

Revenue Recognition - The Company recognizes base rental revenue 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
multi-family residential property under operating leases having terms generally
of one year or less is recognized when earned.


                                      F-6
<PAGE>

      The Company receives reimbursements 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 12).

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 in income over the life of the contracts as adjustments to
interest expense. Gains and losses are deferred and amortized 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 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. FASB No. 128 is effective for the year ended
December 31, 1997, and all prior annual and quarterly periods have been
restated.

Dividends and Distributions Payable - The dividends and distributions payable at
December 31, 1997 represents dividends payable to shareholders of record on
January 5, 1998 (49,856,289 shares), distributions payable to minority interest
common unitholders (6,097,477 common units) on that same date and preferred
distributions to preferred unitholders (230,562 preferred units) for the fourth
quarter 1997. The fourth quarter 1997 dividends and common unit distributions of
$0.50 per share and per common unit (pro-rated for units issued during quarter),
as well as the pro-rated fourth quarter preferred unit distribution aggregating
$888, were approved by the Board of Directors on December 17, 1997 and were paid
on January 16, 1998.

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

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.
The Company provides additional pro forma disclosures as required under
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("FASB No. 123"). See Note 13.

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

Reclassifications - Certain reclassifications have been made to prior period
balances in order to conform with current period presentation.

3) Acquisitions/Transactions

In 1995, the Company acquired 27 office and office/flex properties totaling
approximately 1.6 million square feet for a total cost of approximately
$150,630. The acquired properties are all located in New Jersey and New York.

      In 1996, the Company acquired 15 office properties and completed
construction on two office/flex properties totaling approximately 3.4 million
square feet for a total cost of approximately $451,623. The acquired and
constructed properties are all located in New Jersey and Pennsylvania.
Concurrently with the acquisition of 103 Carnegie Center in Princeton, Mercer
County, New Jersey, the Company sold its office building at 15 Essex Road in
Paramus, Bergen County, New Jersey ("Essex Road"). The concurrent transactions
with unrelated parties qualified as a tax-free exchange, as the Company used
subsequently all of the proceeds from the sale of Essex Road to acquire 103
Carnegie Center.

Notes
Mack-Cali Realty Corporation and Subsidiaries

      On January 28, 1997, the Company acquired 1345 Campus Parkway ("1345
Campus"), a 76,300 square foot office/flex property, located in Wall Township,
Monmouth County, New Jersey, for approximately $6,729 in cash, made available

      On January 31, 1997, the Company acquired 65 properties ("RM Properties")
from Robert Martin Company, LLC and affiliates ("RM") for a total cost of
approximately $450,000. The cost of the transaction (the "RM Transaction") was
financed through the assumption of $185,283 of mortgage indebtedness ("TIAA
Mortgage"), the payment of approximately $220,000 in cash, substantially all of
which was obtained from the Company's cash reserves, and the issuance of
1,401,225 common units, valued at $43,788.

      The RM Properties consist primarily of 54 office and office/flex
properties aggregating approximately 3.7 million square feet and six
industrial/warehouse properties aggregating approximately 387,000 square feet.
The RM Properties are located primarily in established business parks in
Westchester County, New York and Fairfield County, Connecticut. The Company has
agreed not to sell certain of the RM Properties for a period of seven years
without the consent of the RM principals, except for sales made under certain
circumstances and/or conditions.

      In connection with the RM Transaction, the Company was granted a
three-year option to acquire two properties (the "Option Properties"), under
certain conditions, one of which was acquired in 1997 (see below). The purchase
price for the remaining Option Property, under the agreement, is subject to
adjustment based on different formulas and is payable in cash or common units.

      In connection with the RM Transaction, the Company holds a $7,250 mortgage
loan ("Mortgage Note Receivable") secured by the remaining Option Property (see
Note 6).

      On May 8, 1997, the Company acquired four buildings in the Westlakes
Office Park ("Westlakes"), a suburban office complex located in Berwyn, Chester

      On August 15, 1997, the Company acquired one of the Option Properties, 200
Corporate Boulevard South ("200 Corporate"), an 84,000 square-foot office/flex
building located in Yonkers, Westchester County, New York. The property was
acquired for approximately $8,078 through the exercise of a purchase option
obtained in connection with the RM Transaction. The acquisition cost, net of the
mortgage prepayment described below, was financed from the Company's cash
reserves.

      In conjunction with the acquisition of 200 Corporate, the sellers of the
property, certain RM principals, prepaid $4,350 of the $11,600 Mortgage Note
Receivable between the Company and such RM principals (See Note 6).

      On September 3, 1997, the Company acquired Three Independence Way ("Three

      On December 11, 1997, the Company acquired 54 office properties (the "Mack
Properties") from the Mack Company and Patriot American Office Group (the "Mack
Transaction"), pursuant to a Contribution and Exchange Agreement (the
"Agreement"), for a total cost of approximately $1,102,024.

      The Mack Properties consist of 54 office properties comprising a total of
approximately 9.2 million net rentable square feet, ranging from approximately
40,000 to 475,100 square feet. The Mack Properties are located primarily in the
Northeast and Southwest, with a concentration of properties located in Northern
New Jersey (25 properties compromising approximately 4.8 million square feet),
Texas (17 properties comprising approximately 2.5 million square feet) and
Arizona (four properties comprising 485,000 square feet).

      The total cost of the Mack Transaction was financed as follows: (i)
$498,757 in cash made available from the Company's cash reserves and from the
$200,000 Prudential Term Loan (See Note 7), (ii) $291,879 in debt assumed by the
Company (the "Mack Mortgages"), (iii) the issuance of 1,965,886 common units,
valued at $66,373, (iv) the issuance of 15,237 Series A preferred units and

Contingent Units have no voting, distribution or


                                      F-8
<PAGE>

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.

      With the Mack Transaction, the Company assumed an aggregate of
approximately $291,879 of mortgage indebtedness with eight separate lenders,
encumbering 17 of the Mack Properties. Such debt matures at various dates from
March 1998 through January 2009. The Mack Mortgages are comprised of an
aggregate of approximately $199,931 of fixed rate debt bearing interest at a
weighted average rate of approximately 7.66 percent per annum, certain of which
require monthly principal amortization payments, and an aggregate of
approximately $91,948 in variable rate debt bearing interest at a weighted
average floating rate of approximately 76 basis points over the London
Inter-Bank Offered Rate (LIBOR). See Note 7.

      With the completion of the Mack Transaction, the Cali Realty Corporation
name was changed to Mack-Cali Realty Corporation, and the name of the Operating
Partnership was changed from Cali Realty, L.P. to Mack-Cali Realty, L.P.

      In connection with the Mack Transaction, Brant Cali, Brad W. Berger,
Angelo R. Cali, Kenneth A. DeGhetto, James W. Hughes and Alan Turtletaub
resigned from the Board of Directors of the Company. Mitchell E. Hersh, William
L. Mack and Earle I. Mack were added to the Board as "inside" members, and
Martin D. Gruss, Jeffrey B. Lane, Vincent Tese and Paul A. Nussbaum were added
as independent members.

      In accordance with the Agreement, Thomas A. Rizk remained Chief Executive
Officer and resigned as President of the Company, with Mitchell E. Hersh
appointed as President and Chief Operating Officer. The Company's other officers
retained their existing positions and responsibilities, except that Brant Cali
resigned as Chief Operating Officer and John R. Cali resigned as Chief
Administrative Officer. Brant Cali and John R. Cali remained as officers of the
Company as Executive Vice Presidents.

      Entering into new employment agreements with the Company after the Mack
Transaction were Thomas A. Rizk, Mitchell E. Hersh, Brant Cali, and John R.
Cali. Entering into amended and restated employment agreements were Roger W.
Thomas, as Executive Vice President, General Counsel and Assistant Secretary,
Barry Lefkowitz, as Executive Vice President and Chief Financial Officer and
Timothy M. Jones, as Executive Vice President.

      Additionally, the Company entered into non-competition agreements with
each of William, Earle, David and Fredric Mack, which restricted the business
dealings of such individuals relative to their involvement in commercial real
estate activities to those specified in the Agreement. The non-competition
agreements have a term of the later of (a) three years from the completion of
the Mack Transaction, or (b) the occurrence of specified circumstances
including, but not limited to, the removal of William, Earle, David or Fredric
Mack, respectively, from the Company's Board of Directors or Advisory Board, as
applicable, and a decrease in certain ownership levels.

      In connection with the Mack Transaction, under each of the Company's
executive officer's then existing employment agreements, due to a change of
control of the Company (as defined in each employment agreement), each of the
aforementioned officers received the benefit of the acceleration of (i) the
immediate vesting and issuance of his restricted stock, including tax gross-up
payments associated therewith, (ii) the forgiveness of his Stock Purchase Rights
loan, including tax gross-up payments associated therewith, and (iii) the
vesting of his unvested employee stock options and warrants. Additionally, under
each of Thomas Rizk's, Brant Cali's and John R. Cali's employment agreements
with the Company, each of these officers became entitled to receive certain
severance-type payments, as a result of certain provisions in each of their
agreements, triggered as result of the Mack Transaction. Finally, certain
officers and employees of the Company were given transaction-based payments as a
reward for their efforts and performance in connection with the Mack
Transaction. The total expense associated with the acceleration of vesting of
restricted stock, the forgiveness of Stock Purchase Rights loans, and the
payment of certain severance-type payments, as well as performance payments and
related tax-obligation payments, which were approved by the Company's Board of
Directors and which took place simultaneous with completion of the Mack
Transaction, totaled $45,769. Such expenses are included in non-recurring
merger-related charges for the year ended December 31, 1997. See Note 13.

      On December 19, 1997 the Company acquired 100 Overlook Center ("Princeton
Overlook") a 149,600 square-foot office building located in Princeton, Mercer
County, New Jersey. The property was acquired for approximately $27,218, which
was funded through the issuance of 41,421 common units valued at $1,624, with
the remaining cash portion made available from drawing on one of the Company's
credit facilities.

      Additionally, on December 19, 1997, the Company acquired 200 Concord Plaza
Drive ("Concord Plaza"), a 248,700 square-foot office building located in San
Antonio, Bexar County, Texas. The property was acquired for approximately
$34,075, which was made available from drawing on one of the Company's credit
facilities.

      On January 23, 1998, the Company acquired 10 acres of vacant land in the
Stamford Executive Park, located in Stamford, Fairfield County, Connecticut for
approximately $1,300, which was funded from the Company's cash reserves. The
vacant land, on which the Company plans to develop a 40,000 square-foot
office/flex property, was acquired from RMC Development Co., LLC. In conjunction
with the acquisition of the developable land, the Company signed a 15-year
lease, on a triple-net basis, with a single tenant to occupy the entire property
being developed.

Notes
Mack-Cali Realty Corporation and Subsidiaries

      On January 30, 1998, the Company acquired a 17-building office/flex
portfolio, aggregating approximately 748,660 square feet located in the
Moorestown West Corporate Center in Moorestown, Burlington County, New Jersey
and in Bromley Commons in Burlington, Burlington County, New Jersey. The 17
properties were acquired for a total cost of approximately $46,993. The Company
is under contract to acquire an additional four office/flex properties in the
same locations. The Company also has an option to purchase a property following
completion of construction and required lease-up for approximately $3,700. The
purchase contract also provides the Company a right of first refusal to acquire
up to six additional office/flex properties totaling 202,000 square feet upon
their development and lease-up. The initial transaction was funded primarily
from drawing on one of the Company's credit facilities as well as the assumption
of mortgage debt with an estimated value of $8,419 (the "McGarvey Mortgages").
The McGarvey Mortgages currently have a weighted average annual effective
interest rate of 6.24 percent and are secured by five of the office/flex
properties acquired.

      On February 2, 1998, the Company acquired 2115 Linwood Avenue, a 68,000
square-foot vacant office building located in Fort Lee, Bergen County, New

as the assumption of mortgage debt with an estimated value of $12,104 which
bears interest at an annual effective interest rate of 6.52 percent.

      On February 25, 1998, the Company acquired 10 Mountainview Road, a 192,000
square-foot office building, located in Upper Saddle River, Bergen County, New
Jersey. The property was acquired for approximately $24,500, which was made
available from proceeds received from the Company's February 1998 offering of
common stock (see Note 13).

      As of February 27, 1998, the Company's portfolio consisted of 209
properties aggregating approximately 23.1 million square feet, consisting
primarily of office and office/flex buildings, located in ten states, primarily
in the Northeast and Southwest.

      In March 1998, the Company agreed to acquire for $170,000 substantially
all of the interests in Prudential Business Campus, an 875,000 square-foot
office complex with five office buildings and a daycare center, plus land
parcels, located in Parsippany and East Hanover, Morris County, New Jersey.

      Additionally, in March, the Company signed a contract to purchase Morris
County Financial Center, a 308,215 square-foot two-building office complex also
located in Parsippany, Morris County, New Jersey for $52,500.

      The Company also announced, in March, an agreement to acquire 19
properties from Pacifica Holding Company ("Pacifica"), a private real estate
owner and operator in Denver, Colorado, for $188,000. The acquisition will
include Pacifica's entire 1.4 million square-foot office portfolio, which
includes 19 office buildings, and related operations; and 2.5 acres of land
located in the Denver Tech Center. Pacifica's office properties are located in
suburban Denver and Colorado Springs, Colorado.

TIAA Mortgage

In connection with the RM Transaction, on January 31, 1997, the Company assumed
a $185,283 non-recourse mortgage loan with Teachers Insurance and Annuity
Association of America ("TIAA"), with interest only payable monthly at a fixed
annual rate of 7.18 percent. The TIAA Mortgage is secured and
cross-collateralized by 43 of the RM Properties and matures on December 31,
2003. The Company, at its option, may convert the TIAA Mortgage to unsecured
debt upon achievement by the Company of an investment grade credit rating of
Baa3/BBB- or better. The TIAA Mortgage is prepayable in whole or in part subject
to certain provisions, including yield maintenance.

Harborside Mortgages

In connection with the acquisition of Harborside Financial Center
("Harborside"), on November 4, 1996, the Company assumed existing mortgage debt
and was provided seller-financed mortgage debt aggregating $150,000. The
existing financing, with a principal balance of $104,768 as of December 31,
1997, bears interest at a fixed rate of 7.32 percent per annum for a term of
approximately nine years. The seller-provided financing, with a principal
balance of $45,232 as of December 31, 1997, also has a term of approximately
nine years and initially bears interest at a rate of 6.99 percent per annum. The
interest rate on the seller-provided financing will be reset at the end of the
third and sixth loan years based on the yield of the three-year treasury
obligation at that time, with spreads of 110 basis points in years four through
six and 130 basis points in years seven through maturity.

Mortgage Financing

The $64,508 in mortgage financing (the "Mortgage Financing") consisted of
$43,313, which bore interest at a net cost to the Company equal to a fixed rate
of 8.02 percent per annum and $20,195, which bore interest at a net cost to the
Company equal to a floating rate of 100 basis points over one-month LIBOR with a
lifetime interest rate cap of 11.6 percent. On August 12, 1997, the Company
retired the Mortgage Financing with funds made available primarily from drawing
on the Unsecured Facility (see below). On account of prepayment fees, loan
origination fees, legal fees and other costs incurred in the retirement of the
Mortgage Financing, an extraordinary loss of $3,583, net of minority interest's
share of the loss ($402) was recorded for the year ended December 31, 1997.

CIGNA Mortgages

In connection with the Mack Transaction, the Company assumed non-recourse
mortgage debt (the "CIGNA Mortgages") aggregating $86,650 in principal as of
December 31, 1997, with Connecticut General Life Insurance Company (CIGNA). Such
mortgages, which are secured by five of the Mack Properties, bear interest at a
weighted average annual fixed rate of 7.77 percent and require monthly payments
of interest and principal on various term amortization schedules. The CIGNA
Mortgages mature between March 1998 and October 2003.

Mitsubishi Mortgages

In connection with the Mack Transaction, the Company assumed non-recourse
variable-rate mortgage debt (the "Mitsubishi Mortgages") aggregating $72,204 in
principal as of December 31, 1997 with Mitsubishi Trust and Banking Corporation.
Such mortgages, which are secured by two of the Mack Properties, bear interest
payable monthly at a variable rate of 65 basis points over LIBOR (5.72 percent
at December 31, 1997) and mature between January 2008 and January 2009.

Prudential Mortgages

The Company has mortgage debt (the "Prudential Mortgages") aggregating $62,205
in principal as of December 31, 1997 with Prudential Insurance Company of
America, substantially all of which was assumed in the Mack Transaction. Such
mortgages, which are secured by three properties, bear interest at a weighted
average annual fixed rate of 8.43 percent, all of which require monthly payments
of interest. In addition, certain of the Prudential Mortgages also require
monthly payments of principal, in addition to interest, on various term
amortization schedules. The Prudential Mortgages mature between October 2003 and
July 2004.

Other Mortgages

The Company has mortgage debt ("Other Mortgages") aggregating $88,474 in
principal as of December 31, 1997 with six different lenders, all of which was
assumed in the Mack Transaction, and are secured by eight of the Mack
Properties. The Other Mortgages are comprised of: (i) fixed rate debt
aggregating $69,110, which bears interest at a weighted average fixed rate of
7.11 percent, and require monthly payments of principal and interest on various
term amortization schedules, and (ii) variable rate debt aggregating $19,364,
which bears interest at 115 basis points over LIBOR. The Other Mortgages mature
between February 1999 and September 2005.

Prudential Term Loan

On December 10, 1997, the Company obtained a $200,000 term loan (the "Prudential
Term Loan") from Prudential Securities Credit Corp. ("PSC"). The proceeds of the
loan were used to fund a portion of the cash consideration in completion of the
Mack Transaction. The loan has a one-year

Notes
Mack-Cali Realty Corporation and Subsidiaries

term and interest payments are required monthly at an interest rate of 110
basis points over one-month LIBOR. The loan is a recourse loan secured by 11
properties owned by the Company and located in New Jersey.

Revolving Credit Facilities

First Prudential Facility - The Company had a $70,000 revolving credit facility
(the "First Prudential Facility") with PSC. The First Prudential Facility bore
interest at a floating rate equal to 150 basis points over one-month LIBOR for
the period January 1, 1996 through August 31, 1996. Effective September 1, 1996,
the interest rate was reduced to a floating rate equal to 125 basis points over
one-month LIBOR. In conjunction with obtaining the Unsecured Facility (see
below), the Company repaid in full and terminated the First Prudential Facility
on August 7, 1997. The Company had outstanding borrowings of $6,000 at December
31, 1996 under the First Prudential Facility.

Bank Facility - The Company had a revolving credit facility (the "Bank
Facility"), secured by certain of its properties, in the amount of $75,000 from
two participating banks. The Bank Facility had a three-year term and bore
interest at 150 basis points over one-month LIBOR. In conjunction with obtaining
the Unsecured Facility (see below), the Company repaid in full and terminated
the Bank Facility on August 7, 1997. The Company had outstanding borrowings of
$23,805 at December 31, 1996 under the Bank Facility.

Second Prudential Facility - The Company has a revolving credit facility
("Second Prudential Facility") from PSC in the amount of $100,000 which
currently bears interest at 110 basis points over one-month LIBOR, and matures
on March 31, 1999. The Second Prudential Facility is a recourse liability of the
Operating Partnership and is secured by the Company's equity interest in
Harborside. The terms of the Second Prudential Facility include certain
restrictions and covenants that limit, among other things, dividend payments and
additional indebtedness and that require compliance with specified financial
ratios and other financial measurements. The Company had no outstanding
borrowings at December 31, 1997 and 1996 under the Second Prudential Facility.

Unsecured Facility - On August 6, 1997, the Company obtained an unsecured
revolving credit facility (the "Unsecured Facility") in the amount of $400,000
from a group of 13 lender banks. The Unsecured Facility has a three-year term
and currently bears interest at 125 basis points over one-month LIBOR. Based
upon the Company's achievement of an investment grade long-term unsecured debt
rating, the interest rate will be reduced, on a sliding scale, and a competitive
bid option will become available.

      The terms of the Unsecured Facility include certain restrictions and
covenants which limit, among other things, dividend payments and additional
indebtedness and which require compliance with specified financial ratios and
other financial measurements. The Unsecured Facility also requires a fee on the
unused balance payable quarterly in arrears, at a rate ranging from one-eighth
of one percent to one-quarter of one percent of such balance, depending on the
level of borrowings outstanding in relation to the total facility commitment.

      The lending group for the Unsecured Facility consist of: Fleet National
Bank, The Chase Manhattan Bank, and Bankers Trust Company, as agents; PNC Bank,
N.A., Bank of America National Trust and Savings Association, Commerzbank AG,
and The First National Bank of Chicago, as co-agents; and KeyBank, Summit Bank,
Crestar Bank, Mellon Bank, N.A., Signet Bank, and KredietBank NV.

      In conjunction with the Company obtaining the Unsecured Facility, the
Company drew funds on the new facility to repay in full and terminate both the
First Prudential Facility and the Bank Facility. The Company had outstanding
borrowings of $122,100 at December 31, 1997 under the Unsecured Facility.

Contingent Obligation

As part of the Harborside acquisition, 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. For the year ended December 31, 1997, interest was imputed
on the Contingent Obligation, thereby increasing the balance of the Contingent
Obligation to $5,734 as of December 31, 1997.

Interest Rate Contracts

The Company has 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 through August 1999.

      The Company has another interest rate swap agreement with a commercial
bank. This swap agreement has a three-year term and a notional amount of
$26,000, which fixes the Company's one-month LIBOR base to 5.265 percent per
annum through January 1999.

      On November 20, 1997, the Company entered into a seven-year, interpolated
U.S. Treasury interest rate lock agreement with a commercial bank. The agreement
fixes the Company's base Treasury rate to 5.88 percent per annum on a notional
amount of $150,000.

      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 its counterparties.

Company for the years ended December 31, 1997, 1996 and 1995 was $820, $118 and
$27, respectively.

8) Minority Interest

Minority interest in the accompanying consolidated financial statements relates
to common units in the Operating Partnership, in addition to certain preferred
units in the Operating Partnership issued in conjunction with the Mack
Transaction, held by parties other than the Company. Preferred and common units
issued during 1997 are described in Note 3.

Preferred Units

As described in Note 3, in connection with the funding of the Mack Transaction,
the Company issued 15,237 Series A Preferred Units and 215,325 Series B
Preferred Units, with an aggregate value of $236,490. 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 is an amount equal to
the greater of (i) $16.875 (representing 6.75 percent of the stated value of
$1,000 per Preferred Unit on an annualized basis) 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 common 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 after one year for an equal number of shares of common stock.

      The Preferred Unit to common unit conversion rate of $34.65 per common
unit was less than the $39.0625 closing stock price on the date of closing of
the Mack Transaction. Accordingly, on December 11, 1997, the financial value
ascribed to this beneficial conversion feature inherent in the Preferred Units
upon issuance totaled $26,801 ($29,361 before allocation to minority common
unitholders) and was recorded as beneficial conversion feature in stockholders'
equity. The beneficial conversion feature was amortized in full as the Preferred
Units were immediately convertible upon issuance; such amortization was included
in minority interest for the year ended December 31, 1997.

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.

      As described in Note 3, the Company issued an aggregate of 3,408,532
common units in 1997 in connection with the completion of the RM Transaction,
the Mack Transaction and Princeton Overlook.

Contingent Common and Preferred Units

In conjunction with the completion of the Mack Transaction, 2,006,432 contingent
Common units, 11,895 Series A contingent Preferred Units and 7,799 Series B
contingent Preferred Units (collectively, the "Contingent Units") were issued as
contingent non-participating 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.

Unit Warrants

As described in Note 3, in connection with the funding of the Mack Transaction,
the Company granted warrants to purchase 2,000,000 common units.

      The Unit Warrants are exercisable at any time after one year from the date
of their issuance and prior to the fifth anniversary thereof at an exercise
price of $37.80 per common unit.

Notes
Mack-Cali Realty Corporation and Subsidiaries

Minority Ownership

As of December 31, 1997 and 1996, the minority interest common unitholders owned
10.9 percent (20.4 percent, including the effect of the conversion of Preferred
Units into common units) and 6.9 percent of the Operating Partnership,
respectively (in all cases, excluding the effect of any exercise of Unit
Warrants).

9) 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 "Plan"). The 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. No employer contributions have been made to date.

10) Disclosure of Fair Value of Financial Instruments

The following disclosure of estimated fair value was determined by management
using available market information and appropriate valuation methodologies.
However, considerable judgement is necessary to interpret market data and
develop estimated fair value. Accordingly, the estimates presented herein are
not necessarily indicative of the amounts the Company could realize on
disposition of the financial instruments at December 31, 1997 and 1996. The use
of different market assumptions and/or estimation methodologies may have a
material effect on the estimated fair value amounts.

      Cash equivalents, receivables, accounts payable, and accrued expenses and
other liabilities are carried at amounts which reasonably approximate their fair
values.

      Mortgages and loans payable had an aggregate carrying value of $972,650
and $268,010 as of December 31, 1997 and 1996, respectively, which approximates
their estimated aggregate fair value (excluding prepayment penalties) based upon
then current interest rates for debt with similar terms and remaining
maturities.

      The estimated cost to settle the Company's interest rate contracts, at
December 31, 1997 and 1996, based on quoted market prices of comparable
contracts was $1,404 and $140, respectively.

      Disclosure about fair value of financial instruments is based on pertinent
information available to management as of December 31, 1997 and 1996. Although
management is not aware of any factors that would significantly affect the fair
value amounts, such amounts have not been comprehensively revalued for purposes
of these financial statements since December 31, 1997 and current estimates of
fair value may differ significantly from the amounts presented herein.

Other Contingencies

On December 10, 1997, a Shareholder's Derivative Action was filed in Maryland
Court on behalf of one individual shareholder. The complaint questioned certain
executive compensation decisions made by the Company's Board of Directors in
connection with the Mack Transaction. The Board's compensation decisions were
discussed in the proxy materials distributed in connection with the Mack
Transaction and were approved by in excess of 99 percent of the voting
shareholders. Although the Company believes that this lawsuit is factually and
legally baseless, the Company recorded $750 for this litigation, which is
included in non-recurring merger-related charges for the year ended December 31,
1997.

      The Company is a defendant in certain other 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.

12) Tenant Leases

The Properties are leased to tenants under operating leases with various
expiration dates through 2020. 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.

      Future minimum rentals to be received under non-cancelable operating
leases at December 31, 1997 are as follows:

13) 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 (defined to include certain entities), at any time
during the last half of any taxable year of the Company, other than its initial
taxable year 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.

      On August 13, 1996, the Company sold 3,450,000 shares of its common stock
through a public stock offering (the "August 1996 Offering"), which included an
exercise of the underwriters over-allotment option of 450,000 shares. Net
proceeds from the August 1996 Offering (after offering costs) were approximately
$76,830.

      On November 22, 1996, the Company completed an underwritten public offer
and sale of 17,537,500 shares of its common stock. The Company received
approximately $441,215 in net proceeds (after offering costs) from the offering,
and used such funds to complete certain of the Company's property acquisitions
in November and December 1996, pay down outstanding borrowings on its revolving
credit facilities, and invest in Overnight Investments.

      On May 15, 1997, the stockholders approved an increase in the authorized
shares of common stock in the Company to 190,000,000.

      On October 15, 1997, the Company completed an underwritten public offer
and sale of 13,000,000 shares (the "1997 Offering") of its common stock. The
Company received approximately $489,116 in net proceeds (after offering costs)
from the 1997 Offering. The Company used $160,000 of such proceeds to repay
outstanding borrowings on its Unsecured Facility and the remainder of the
proceeds to fund a portion of the purchase price of the Mack Transaction, for
other acquisitions, and for general corporate purposes.

      On February 25, 1998, the Company completed an underwritten public offer
and sale of 2,500,000 shares of its common stock (the "1998 Offering") and used
the net proceeds, of approximately $92,000 (after offering costs) to pay down a
portion of its outstanding borrowings under the Unsecured Facility and to
fund the acquisition of Mountainview (see Note 3).

Stock Option Plans

In 1994, and as subsequently amended, the Company established the Cali Employee
Stock Option Plan ("Employee Plan") and the 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 and 1997 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 a result of provisions contained in certain of the Company's executive
officers' employment agreements, on December 11, 1997, the Mack Transaction
triggered the accelerated vesting of unvested stock options held by such
officers on that date.

      Information regarding the Company's stock option plans is summarized
below:

      The weighted-average fair value of options granted during 1997, 1996, and
1995 were $6.66, $2.41, and $1.28 per option, respectively. The fair value of
each significant option grant is estimated on the date of grant using the
Black-Scholes model. The following weighted average assumptions are included in
the Company's fair value calculations of stock options:

Warrants

On January 31, 1997, in conjunction with the completion of the RM Transaction,
the Company granted a total of 400,000 warrants to purchase an equal number of
shares of common stock at $33 per share (the market price at date of grant) to
Timothy Jones, Brad Berger and certain other Company employees formerly with RM.
Such warrants vest equally over a three-year period and have a term of ten
years. The unvested warrants held by Timothy Jones and Brad Berger became
immediately exercisable on December 11, 1997 as a result of provisions contained
in their employment agreements, which were triggered by the Mack Transaction.

      On December 12, 1997, in conjunction with the completion of the Mack
Transaction, the Company granted a total of 491,756 warrants to purchase an
equal number of shares of common stock at $38.75 per share (the market price at
date of grant) to Mitchell Hersh, and certain other Company executives formerly
with Patriot American Office Group. Such warrants vest equally over a five-year
period and have a term of ten years.

      The weighted-average fair value of warrants granted during 1997 were $6.27
per warrant. No warrants were granted in 1995 or 1996. The fair value of each
warrant grant is estimated on the date of grant using the Black-Scholes model.
The following weighted average assumptions are included in the Company's fair
value calculation of warrants granted during 1997:

- --------------------------------------------------------------------------------
Expected life (years)                                                         6

Dividend yield                                                             5.29%
================================================================================

FASB No. 123

Under the above models, the value of stock options and warrants granted during
1997, 1996 and 1995 totaled approximately $22,998, $1,955, and $294,
respectively, which would be amortized ratably on a pro forma basis over the
appropriate vesting period. Had the Company determined compensation cost for
these granted securities in accordance with FASB No. 123, the Company's pro
forma net (loss) income and basic (loss) earnings per share and diluted (loss)
earnings per share would have been ($3,153), ($0.08) and ($0.08) in 1997,
$31,980, $1.73 and $1.49 in 1996 and $13,553, $1.22 and $0.97 in 1995,
respectively. The FASB No. 123 method of accounting does not apply to options
granted prior to January 1, 1995 and accordingly, the resulting pro forma
compensation cost may not be representative of that to be expected in the
future.

Stock Compensation

In January 1997, the Company entered into employment contracts with seven of its
key executives which provided for, among other things, compensation in the form
of stock awards (the "Restricted Stock Awards") and Company-financed stock
purchase rights (the "Stock Purchase Rights"), and associated tax obligation
payments. In connection with the Restricted Stock Awards, the executives were to
receive 199,070 shares of the Company's common stock vesting over a five-year
period contingent on the Company meeting certain performance objectives.
Additionally, pursuant to the terms of the Stock Purchase Rights, the Company
provided fixed rate, non-recourse loans, aggregating $4,750, to such executives
to finance their purchase of 152,000 shares of the Company's common stock, which
the Company agreed to forgive ratably over five years, subject to continued
employment. Such loans were for amounts equal to the fair market value of the
associated shares at the date of grant. Subsequently, from April 18, 1997
through April 24, 1997, the Company purchased, for constructive retirement,
152,000 shares of its outstanding common stock for $4,680. The excess of the
purchase price over par value was recorded as a reduction to additional paid-in
capital. Concurrent with this purchase, the Company sold to the Operating
Partnership 152,000 Units for $4,680.

      The value of the Restricted Stock Awards and the balance of the loans
related to the Stock Purchase Rights at the grant date, were recorded as
unamortized stock compensation in stockholders' equity. As a result of
provisions contained in certain of the Company's executive officers' employment
agreements, which were triggered by the Mack Transaction on December 11, 1997,
the loans provided by the Company under the Stock Purchase Rights were forgiven
by the Company, and the vesting and issuance of the restricted stock issued
under the Restricted Stock Awards was accelerated, and the related tax
obligation payments were made. As a result, the accelerated cost of $16,788
affecting the stock compensation described above was included in non-recurring
merger-related charges for the year ended December 31, 1997. With such
accelerated vestings, there was no remaining balance in unamortized stock
compensation as of December 31, 1997.

      Included in general and administrative expense for the year ended December
31, 1997 is $2,257 relating to the normal cost of the Restricted Stock Awards
and Stock Purchase Rights.

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 Preferred Units and Contingent Units issued in 1997 were not included
in the computation of diluted EPS as such units were anti-dilutive during the
period.

      On February 25, 1998, the Company sold 2.5 million shares of its common
stock in the 1998 Offering.

14) Impact of Recently Issued Accounting Standards

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 130, Reporting Comprehensive Income ("FASB
No. 130"), which establishes standards for the reporting and display of
comprehensive income and its components. This statement requires a separate
statement to report the components of comprehensive income for each period
reported. The provisions of this statement are effective for fiscal years
beginning after December 15, 1997. Management believes that they currently do
not have items that would require presentation in a separate statement of
comprehensive income.

      In June 1997, the FASB also issued Statement of Financial Accounting
Standards No. 131, Disclosures about Segments of an Enterprise and Related
Information, ("FASB No. 131"), which establishes standards for the way that
public business enterprises report information about operating segments in
annual financial statements and require that those enterprises report selected
information about operating segments in interim financial reports issued to
shareholders. This statement is effective for financial statements for periods
beginning after December 15, 1997, and requires that comparative information
from earlier years be restated to conform to the requirements of this standard.

15) Pro Forma Financial Information (unaudited)

The following pro forma financial information for the years ended December 31,
1997 and 1996 are presented as if the acquisitions, disposition and common stock
offerings in 1996, the RM Transaction, the Mack Transaction and 1997 stock
offering and the 1997 acquisitions of 1345 Campus, Westlakes, Shelton Place, 200
Corporate, Three Independence, The Trooper Building, Concord Plaza and Princeton
Overlook had all occurred on January 1, 1996. The pro forma financial
information excludes any deduction for the non-recurring merger-related charges
and the beneficial conversion feature charge included in the Company's
historical information for the year ended December 31, 1997. 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, 1996, nor do they represent the
results of operations of future periods.

Agreement shall be void ab initio and shall be of no force or effect and neither
the Cali Group nor the Contributor shall have any further obligation to the

action against CRLP for the payment of the Deposit, but neither CRLP nor Cali
shall have any other or further liability in excess of the Deposit.

         2.2 At Closing, CRLP shall issue to Contributor and/or the Unit Holders

Certificates shall contain the legend set forth in Section 5.5. All rights and

(including, without limitation, Sections 4, 5, 7, 8, 9, 10, 12 and 21), all of
which rights are expressly reserved (and are not waived) by CRLP. Contributor

         4.1 The Property is to be contributed to CRLP subject only to the
following (collectively, the "Permitted Encumbrances"):

         (a) the liens of real estate taxes, personal property taxes, water
charges, and sewer charges provided same are not due and payable, but subject to
adjustment as provided herein;

         (b)  the rights of  Tenants, as tenants only;

         (c) those restrictions, covenants, agreements, easements, matters and
things affecting title to the Real Property as of the date hereof and more
particularly described in Schedule 4.1(c) annexed hereto and by this reference
made a part hereof;

         (d) any and all laws, statutes, ordinances, codes, rules, regulations,
requirements, or executive mandates affecting the Real Property as of the date
hereof, so long as there are no engineering or institutional controls including,
without limitation, a deed notice or declaration of environmental restrictions,
a groundwater classification exception area or well restriction area affecting
the Real Property;

         (e) the state of facts shown on the survey, if any, described on
Schedule 4.1(e), and any other state of facts which an accurate survey of the
Real Property would actually show, provided same do not impair the use of the
Real Property as it is currently being used and do not render title uninsurable
at standard rates; and
<PAGE>

         (f) the Service Contracts, excluding, however, any Service Contract
CRLP advises Contributor to terminate prior to Closing.

         4.2 (a) CRLP has, prior to the date hereof, directed Stewart Title
Insurance Company ("Title Company") to prepare, and the Title Company has
prepared and delivered to CRLP and Contributor, title insurance searches and
commitments for an owner's title insurance policy for the Real Property (the
"Title Commitment") which is annexed hereto as Schedule 4.2(a). Contributor
agrees that all of the requirements marked "satisfy" set forth in Schedule B,
Section I of the Title Commitment shall be met prior to Closing, and that all of
the items marked "Omit by Contributor" set forth in Schedule B, Section II of
the Title Commitment shall be removed prior to Closing. In addition, if CRLP
shall become aware of any defects, objections or exceptions in the title to the
Real Property which do not appear in the Title Commitment and are not Permitted
Encumbrances ("New Title Defects"), Contributor shall use its good faith efforts
to remove such New Title Defects prior to Closing provided, however, Contributor
shall not be required to institute any litigation or incur any expense in
connection therewith, except for professional and other fees and expenses in an
amount not to exceed $2,000.00 in each instance, unless CRLP agrees to pay such
fees and expenses in excess of $2,000.00 on Contributor's behalf. Contributor
shall have the right to adjourn the Closing for up to sixty (60) days in order
to eliminate unacceptable defects, objections or exceptions. If after complying
with the foregoing requirements, Contributor is unable to eliminate all
unacceptable defects, objections or exceptions in accordance with the terms of
this Agreement on or before such adjourned date for the Closing, CRLP may elect
either (w) to terminate this Agreement by notice given to Contributor, in which
event the provisions of Section 4.7 shall apply, or (x) to accept title subject
to such unacceptable defects, objections or exceptions and receive no credit
against or reduction of the Consideration. Contributor agrees and covenants that
it shall not voluntarily place any encumbrances or restrictions to title to the
Real Property from and after the date of the first issuance of the Title
Commitment for the Real Property.
<PAGE>

                  4.2 (b) CRLP has been advised that First American Title
Insurance Co., by its agent General Land Abstract Co. ("First American") will
issue a title commitment for the Real Property without requiring any of the
following: consent of Troast Overlook Associates (Troast"), Troast's execution
of the Deed, review of Troast's partnership agreement, or any proofs regarding
Troast (collectively the "Troast Requirements"). If the Title Company will not
reissue the Title Commitment without the Troast Requirements, and if First
American or any other major title insurer (e.g. Chicago Title or Lawyers Title)
reasonably acceptable to CRLP (the "Major Title Insurers") will insure title to
the Real Property without the Troast Requirements and otherwise in accordance
with the terms of this Agreement and subparagraph (a) above, CRLP will accept
such insurance. If the Title Company, First American or the Major Title Insurers
will not insure title to the Real Property without exceptions for the Troast
Requirements and Contributor is unable to have them removed, CRLP may elect to
either (i) terminate this Agreement, in which event the provisions of Section
4.7 shall apply or (ii) accept title subject to the Troast Requirements and
receive no credit against or reduction of the Consideration.


[THE REMAINDER OF THIS PAGE HAS BEEN LEFT BLANK INTENTIONALLY]
<PAGE>

         4.3 It shall be a condition to Closing that Contributor conveys, and
that the Title Company insure, title to the Real Property in the amount of the
Consideration (at a standard rate for such insurance) in the name of CRLP or its
designee, after delivery of the Deed, by a standard 1992 ALTA Owners Policy that
is consistent in all respects with the Title Commitment (the "Title Policy").
Contributor shall provide a standard New Jersey title affidavit substantially in
the form annexed hereto as Schedule 4.3, as well as such undertakings as the
Title Company insuring title to the Real Property may reasonably require in
order to cure all other defects and exceptions other than the Permitted
Encumbrances, as required pursuant to Section 4.2. The words "insurable title"
and "insurable" as used in this Agreement are hereby defined to mean title which
is insurable by the Title Company without exception other than the Permitted
Encumbrances and any other matters provided the Title Company is willing to
insure CRLP against any loss or liability by reason thereof.

         4.4 Prior to Closing, CRLP shall cause one or more surveyors reasonably
acceptable to CRLP (a) to certify and warrant to CRLP and the Title Company the
square footage and acreage of the Land (to the nearest one-one hundredth
(1/100)), (b) to certify that the survey is a complete and accurate
representation of the Real Property, (c) to certify that there are no gores,
gaps or strips, and such other facts that are customarily required by the Title
Company, (d) to provide to CRLP and the Title Company a metes and bounds
description of the Land and any off-site private easements benefiting the Real
Property, and (e) otherwise prepare the survey in accordance with the customary
requirements of a lending institution financing such a transaction. CRLP shall
cause the surveyor to update the survey as of the Closing Date and have the
general survey exception removed from the Title Policy (and replaced by a
specific exception based on the survey) and the survey affirmatively insured to
CRLP. If the metes and bounds description prepared by the surveyor varies from
the deed into Contributor's predecessor, the deed shall contain the metes and
bounds description prepared by the Surveyor only if the survey is certified to
Contributor.

         4.5 Any unpaid taxes, lienable water charges, lienable sewer rents,
together with the interest and penalties thereon to a date not less than one (1)
business day following the Closing Date (in each case subject to any applicable
apportionment), and any mortgages or other liens created by Contributor, which
Contributor is obligated to pay and discharge pursuant to the terms of this
Agreement, together with the cost of recording or filing of any instruments
necessary to discharge such liens and such judgments,
<PAGE>

shall be paid at the Closing by Contributor and Contributor may direct that the
Cash Payment or any part thereof be used to make such payment. Contributor shall
deliver to CRLP, on the Closing Date, instruments in recordable form sufficient
to discharge any such mortgages or other liens which Contributor is obligated to
pay and discharge pursuant to the terms of this Agreement, or, if acceptable to
the Title Company, Contributor shall deliver payoff letters from the lien
holders.

         4.6 If, on the date of this Agreement, the Real Property or any part
thereof shall be or shall have been affected by an assessment or assessments for
municipal improvements which are or may become payable in annual installments,
of which the first installment is either then a charge or lien or has been paid,
then for the purposes of this Agreement all the unpaid installments of any such
assessment, including those which are to become due and payable after the
Closing Date, shall be deemed to be due and payable and to be liens upon the
Real Property and shall be paid and discharged by Contributor on the Closing
Date. Any other assessments shall be the sole responsibility of CRLP.

         4.7 If Contributor is unable to convey title in accordance with the
terms of this Agreement and CRLP elects to terminate this Agreement, then the
Deposit shall be returned to CRLP, this Agreement shall terminate and neither
party to this Agreement shall have any further rights or obligations hereunder
other than those which are expressly stated herein to survive any such
termination.

or regulations affecting the Real Property, or (ii) any violations or conditions
that may give rise thereto, from any agency, board, bureau, commission,
department, office or body of any municipal, county, state or federal
governmental unit, or any subdivision thereof, having, asserting or acquiring
jurisdiction over all or any part of the Real Property or the management,
operation, use or improvement thereof (collectively, the "Governmental
Authorities") and there are no outstanding orders, judgments, injunctions,
decrees, directives or writ of any Governmental Authorities against or involving
Contributor or the Real Property.
<PAGE>

         (i) Annexed hereto as Schedule 5.1(i) is a schedule of all leasing

         (k) Contributor has paid all Taxes (as hereinafter defined) due and
payable as of the date of this Agreement, and Contributor shall pay all Taxes

including expenses associated with contesting any proposed adjustment related to
any of the foregoing.

         (l) Annexed hereto as Schedule 5.1(l) is a listing of the following,
which is true, complete and correct in all material aspects for each Real
Property contributed to CRLP: (i) its adjusted basis as of December 31, 1996;
(ii) the date placed in service; (iii) the depreciation method; and (iv) the
remaining useful life.

         5.2      In order to induce Cali and CRLP to issue the Contributor
Units, Contributor hereby acknowledges its understanding that the
issuance of the Contributor Units is intended to be exempt from
registration under the Securities Act of 1933, as amended, and the
rules and regulations in effect thereunder (the "Act").  In
<PAGE>

furtherance thereof, Contributor represents and warrants to CRLP to as follows:

         (a) Contributor and the Unit Holders are acquiring the Contributor
Units solely for their own account for the purpose of investment and not as a
nominee or agent for any other person and not with a view to, or for offer or
sale in connection with, any distribution of any thereof other than to the Unit
Holders. Contributor agrees and acknowledges that it is not permitted to offer,
transfer, sell, assign, pledge, hypothecate or otherwise dispose of ("Transfer")
any of the Contributor Units except as provided in this Agreement and the
Agreement of Limited Partnership of CRLP, as amended through the date hereof
(the "OP Agreement").

         (b) Contributor and the Unit Holders are knowledgeable, sophisticated
and experienced in business and financial matters. Contributor and the Unit
Holders fully understand the limitations on transfer described in this Agreement
and the OP Agreement. Contributor and the Unit Holders are able to bear the
economic risk of holding the Contributor Units for an indefinite period and are
able to afford the complete loss of their investment in the Contributor Units.
Contributor and the Unit Holders have received and reviewed the OP Agreement and
copies of the documents filed by Cali since its inception under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and all registration
statements and related prospectuses and supplements filed by Cali and declared
effective under the Securities Act of 1933, as amended, since its inception
(collectively, the "SEC Documents") and have been given the opportunity to
obtain any additional information or documents and to ask questions and receive
answers about such documents, Cali and CRLP and the business and prospects of
Cali and CRLP which Contributor and the Unit Holders deem necessary to evaluate
the merits and risks related to its investment in the Contributor Units.
Contributor and the Unit Holders understand and have taken cognizance of all
risk factors related to the purchase of the Contributor Units.

         (c) Contributor and the Unit Holders acknowledge that they have been
advised that (i) the Contributor Units must be held indefinitely, and
Contributor and the Unit Holders will continue to bear the economic risk of the
investment in the Contributor Units, unless they are redeemed pursuant to the OP
Agreement or are subsequently registered under the Act or an exemption from such
registration is available, (ii) it is not anticipated that there will be any
public market for the Units at anytime, (iii) Rule 144 promulgated under the Act
may not be available with respect to the sale of any securities of CRLP (and
that upon redemption of the
<PAGE>

Contributor Units in CRLP for shares of Common Stock a new holding period under
Rule 144 may commence), and CRLP has made no covenant, and makes no covenant, to
make Rule 144 available with respect to the sale of any securities of CRLP
(although Cali and CRLP have agreed to register the Common Stock pursuant to the
Registration Rights Agreement, as hereinafter defined), (iv) a restrictive
legend as set forth in Section 5.5 below shall be placed on the Certificates
representing the Contributor Units, and (v) a notation shall be made in the
appropriate records of CRLP indicating that the Contributor Units are subject to
restrictions on transfer.


         (d) Contributor and the Unit Holders also acknowledge that (i) the
redemption of Contributor Units for shares of Common Stock is subject to certain
restrictions contained in the OP Agreement; and (ii) the shares of said Common
Stock which may be received upon such a redemption may, under certain
circumstances, be restricted securities and be subject to limitations as to
transfer, and therefore subject to the risks referred to in subsection (c)
above. Notwithstanding anything herein or in the OP Agreement to the contrary,
Contributor hereby acknowledges and agrees that it and the Unit Holders may not
exercise the Redemption Rights (as defined in the OP Agreement) until after the
date which is one year from the Closing Date.

         (e) Contributor and each of the Unit Holders is either an "accredited
investor" (as such term is defined in Rule 501 (a) of Regulation D under the
Act) or Contributor and each of the Unit Holders either alone or with its
purchaser representative(s) has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
prospective investment.

         5.3 In addition to the provisions of Section 5.1, Contributor hereby
warrants and represents the following with respect to environmental matters:

violations are noted in the records of or have been issued by any Governmental
Authorities, Contributor shall provide prompt notice thereof to CRLP but will
have no obligation to cure the same prior to Closing provided, however, that if
Contributor elects not to cure the same, then upon notice to CRLP, at CRLP's
election, CRLP may either (i) close title to the Property subject to such
violations and assuming the obligation to pay any fines or penalties imposed

         (m) Contributor, at its sole cost and expense, shall complete all work
under construction by Contributor, its agent(s) or contractor(s) at the Property

certificates of completion and occupancy, or other documentation reasonably
satisfactory to CRLP, evidencing the acceptance of said work by all
<PAGE>

appropriate Governmental Authorities having jurisdiction thereover and the party
for whom the work is being so performed; said obligations shall survive Closing.

         7.2 To the extent that any of the Promotional Materials are not in the

<PAGE>

IV. ADJUSTMENTS.

         11.1 The following items with respect to the Real Property are to be
apportioned as of midnight on the date preceding the Closing:

         (a) Rents, escalation charges and percentage rents payable by Tenants
as and when collected. Unpaid rents, escalation charges and percentage rents for
the month in which Closing takes place and for prior months are hereafter
referred to as Arrearages. CRLP shall make a good faith effort to collect
Arrearages but shall not be obligated to bring any action therefor. Contributor
may attempt to collect Arrearages Contributors but shall not, without CRLP's
consent, which shall not be unreasonably withheld, institute any lawsuit or
collection procedures. In no event and under no circumstances may Contributor
seek to evict any tenant. All payment made for the month in which the Closing
takes place or after Closing by tenants who owe Arrearages shall be applied
first to current rents, escalation charges and percentage rents and then to
Arrearages, if any, in the inverse order of maturity. Notwithstanding the
foregoing, any payment received by either party within ninety (90) days after
the Closing Date from either Novo Nordisk, Xerox Corporation, IDS Financial
Services, Withum, Smith and Brown or Hannoch, Weisman on account of escalation
charges under each of their respective Leases shall be applied first to the
escalation charges for the period prior to the Closing Date with respect to such
Lease. A party which receives a payment to be applied on account of Arrearages
will remit any Arrearages it collects, minus out-of-pocket expenses incurred in
collection such Arrearages, in accordance with the provisions hereafter set
forth. If any Arrearages are received, the recipient shall promptly notify the
other party, identifying the tenant and amount paid. Any Arrearages received by
a party and owned to the other party in accordance with this Section shall be
deemed to be received and held in trust and shall be paid to the party to whom
such Arrearages are owed (as provided herein) promptly after they are received.

         (b) Upon sufficient advance notice, a cashier's or certified check or
wire transfer to the order of CRLP in the amount of all cash Security Deposits
and any prepaid rents, together with interest required to be paid thereon. At
the election of CRLP, such amount may be allotted to CRLP as a credit against
the Cash Payment.

         (c)  Utility charges payable by Contributor including, without
<PAGE>

limitation, electricity, water charges and sewer charges. If there are meters on
the Real Property, Contributor will cause readings of all said meters to be
performed not more than five (5) days prior to the Closing Date.

         (d) Amounts payable under the Service Contracts other than those
Service Contracts which CRLP has elected not to assume.

         (e) Real estate taxes due and payable for the calendar year or fiscal
year, as applicable. If the Closing Date shall occur before the tax rate is
fixed, the apportionment of real estate taxes shall be upon the basis of the tax
rate for the preceding year applied to the latest assessed valuation. If
subsequent to the Closing Date, real estate taxes (by reason of change in either
assessment or rate or for any other reason) for the Real Property should be
determined to be higher or lower than those that are apportioned, a new
computation shall be made, and Contributor agrees to pay CRLP any increase shown
by such recomputation and vice versa.

         (f) The value of fuel stored at any of the Real Property, at
Contributor's most recent cost, including taxes, on the basis of a reading made
within ten (10) days prior to the Closing by Contributor's supplier.

         11.2 At the Closing, Contributor shall deliver to CRLP a list of
additional rent, however characterized, under a Lease including without
limitation, real estate taxes, electrical charges, utility costs and operating
expenses (collectively, "Additional Rents") billed to Tenants for the calendar
year 1997 (both on a monthly basis and in the aggregate), the basis for which
the monthly amounts are being billed and the amounts incurred by Contributor on
account of the components of Additional Rent for calendar year 1997. Upon the
reconciliation by CRLP of the Additional Rents billed to Tenants, and the
amounts actually incurred for the calendar year 1997, Contributor and CRLP shall
be entitled to receive payments from Tenants, as the case may be, on a pro rata
basis based upon each party's period of ownership during calendar year 1997.

         11.3 Except as otherwise provided in this Agreement, the adjustments
shall be made in accordance with the customs in respect to title closings in the
State of New Jersey. Any and all errors in the adjustments will be corrected on
the Closing Date and the provisions of this Section 11 shall survive the Closing
Date.
<PAGE>

         12. CONDITIONS PRECEDENT TO CLOSING.

         12.1 The obligations of Contributor to deliver title to the Property

(all or any of which may be waived, in whole or in part, by Contributor):

upon notice not less than five (5) business days prior to Closing to a directly
or indirectly wholly-owned subsidiary or subsidiaries of Cali or CRLP, or to a
partnership in which any such wholly-owned subsidiary or subsidiaries owns,
either directly or indirectly, at least seventy-five (75%) percent of the
profits, losses and cash flow thereof and controls the management of the affairs
of such partnership (any such entity, a "Permitted Assignee") and any other
assignment or attempted assignment by Cali or CRLP shall be deemed null and void
and of no force and effect. In addition, at Closing, CRLP shall have the right
to cause Contribution to direct the Deed and other closing instruments to such
party as (who shall be deemed to be a Permitted Assignee and bound by the terms
of this Agreement) CRLP shall direct. No such assignment shall relieve Cali and
CRLP from their obligations under this Agreement, and they shall be jointly and
severally liable with permitted assignee for such obligations.


14. BROKER.


         14.1 Cali, CRLP and Contributor represent that they have not dealt with
any brokers, finders or salesmen in connection with this transaction other than
The Garibaldi Group, Ltd. ("Broker"), whose commission shall be paid by
Contributor pursuant to a separate agreement. Cali, CRLP and Contributor agree
to indemnify, defend and hold each other harmless from and against any and all
loss, cost, damage, liability or expense, including reasonable attorneys' fees,
which they may sustain, incur or be exposed to by reason of any claim for fees
or commissions made through the other party. The provisions of this Section
shall survive the Closing or other termination of this Agreement.



15. CASUALTY LOSS.

         15.1 Contributor shall continue to maintain the fire and extended
coverage insurance policies, annexed hereto as Schedule 15.1, with respect to
the Property (the "Insurance Policies") which are currently in effect through
the Closing.

         15.2 If at any time prior to the Closing Date any portion of the Real
Property is destroyed or damaged as a result of fire or any other casualty (a
"Casualty"), Contributor shall promptly give written notice ("Casualty Notice")
thereof to CRLP along with Contributor's estimate, given in good faith, of the
cost to repair
<PAGE>

as a result of the Casualty (the "Repair Cost"). If the Repair Cost is in excess
of $1,000,000.00 then within ten (10) days after the receipt of the Casualty
Notice, CRLP shall have the right, at its sole option, of terminating this
Agreement by written notice to Contributor given within ten (10) days after
receipt of the Casualty Notice. If CRLP does not terminate this Agreement, the
proceeds of any insurance with respect to the Real Property paid between the
date of this Agreement and the Closing Date plus the amount of Contributor's
deductible under the policy insuring the Casualty shall be paid to CRLP at
Closing, and all unpaid claims and rights in connection with losses to the
Property shall be assigned to CRLP at Closing without in any manner affecting
the Consideration.

         15.3 Contributor shall cause all temporary repairs to be made to the
Real Property as shall be required to prevent further deterioration and damage
to the Real Property prior to the Closing Date provided, however, that any such
repairs shall first be approved by CRLP, except if there is an emergency.
Contributor shall have the right to be reimbursed from the proceeds of any
insurance with respect to the Real Property paid between the date of this
Agreement and the Closing Date for the cost of all such repairs.


         16. CONDEMNATION.

         16.1 In the event, that prior to Closing, Contributor receives notice
of the institution or threatened institution of any proceedings, judicial,
administrative or otherwise, by eminent domain or otherwise, which propose to
affect a material portion of the Real Property, Contributor shall give notice (a
"Condemnation Notice") to CRLP promptly thereafter. Within fifteen (15) days
following receipt of the Condemnation Notice, CRLP shall have the right and
option to terminate this Agreement by giving Contributor written notice thereof.
Any damage to or destruction of the Real Property as a result of a taking by
eminent domain shall be deemed "material" for purposes of this Section if the
estimate of the damage, which estimate shall be performed by an insurance
adjuster and CRLP's architect, shall exceed $250,000.00. Should CRLP so
terminate this Agreement in accordance with this Section, neither party shall
have any further liability or obligations to the other. In the event CRLP shall
not elect to cancel this Agreement, Contributor shall assign all proceeds of
such taking to CRLP, same shall be CRLP's sole property, and CRLP shall have the
sole right to settle any claim in connection with the Property, and there shall
be no reduction in the Consideration.
<PAGE>

         16.2 Notwithstanding anything to the contrary contained in Section 16.1
above, the parties acknowledge that a portion of the Real Property is the
subject of a condemnation action pending in the Superior Court of New Jersey Law
Division, Mercer County, Docket No. MER-I-003039-96 and related litigation (the
"Pending Condemnation"). Contributor and CRLP agree that the proceeds of the
Pending Condemnation, whether such proceeds are obtained from judgment,
settlement or by other means, and whether the same are paid prior to or after
the Closing, shall be paid as follows:

         (a)  to Contributor, to the extent of $428,000.00
("Contributor's
Share"), then

         (b) to CRLP, to the extent there are proceeds in excess of $428,000.00.

Contributor shall defend and/or prosecute, as applicable, the Pending
Condemnation, keep CRLP apprised as to the status of such matter, and deliver
copies of all decisions, correspondence or other comunications concerning the
Pending Condemnation to CRLP. Contributor and CRLP shall cooperate with one
another in connection with the Pending Condemnation, and prior to Closing
neither party shall have the right to settle, terminate or make any other
decisions or take any other action respecting the same without the other party's
written consent provided, however, that notwithstanding anything to the contrary
herein contained, Contributor shall have the right to obtain payment of the
Contributor's Share plus any interest thereon payable by the condemning
authority (to the extent such interest relates to the period prior to
Contributor's receipt of Contributor's Share), and CRLP will cooperate with
Contributor in all reasonable respects (at no cost or expense to CRLP) to obtain
such payment immediately after request therefor from Contributor. The provisions
of this Section 16.2 shall survive the Closing Date.


17. TRANSFER RESTRICTIONS; RIGHT OF FIRST REFUSAL.

         17.1 Contributor agrees that the Contributor Units may not be sold,
assigned, transferred, pledged, encumbered or in any manner disposed of
(collectively, "Transferred") or redeemed for shares of Common Stock until the
first anniversary of the Closing Date. Thereafter, the Contributor Units and/or
the shares of Common Stock underlying the Contributor Units (the "Underlying
Shares") may only be Transferred (i) privately in accordance with the terms of
the OP Agreement and this Section 17, or (ii) in the form of Underlying
<PAGE>

Shares only, publicly (subject to the restrictions of the Act and the rules and
regulations promulgated thereunder) in trading blocks of 300,000 shares of
Common Stock or less. Notwithstanding anything herein to the contrary, the
provisions of this Section 17 shall not apply to, and, in addition to any rights
under the OP Agreement, Contributor and the Unit Holders shall have the right to
make the following Transfers: (i) pledges or encumbrances of all or a portion of
the Contributor Units to an institutional lender and/or (ii) Transfers of all or
any portion of the Contributor Units to Permitted Transferees in accordance with
the OP Agreement. "Permitted Transferees" means (i) any entity or individual
comprising Contributor or the Unit Holders; (ii) any direct or indirect equity
owner of Contributor or the Unit Holders; and (iii) members of the Immediate
Family (as defined in the OP Agreement) of Contributor or the Unit Holders (or
any direct or indirect equity owner thereof) and trusts for the benefit of one
or more members of the Immediate Family of Contributor or the Unit Holders (or
any direct or indirect equity owner thereof) created for estate and/or gift tax
purposes. Any holder of Contributor Units pursuant to (i) or (ii) of the
preceding sentence, shall be subject to the applicable terms and conditions of
the OP Agreement and shall sign a counterpart of the OP Agreement to such
effect.

         17.2 If Contributor, the Unit Holders, or any of their Permitted
Transferees (each a "Contributor Party") receives a bona fide written offer to
purchase part or all of its Contributor Units or Underlying Shares in a
privately negotiated transaction which it desires to accept, such Contributor
Party shall not sell, transfer, or otherwise dispose of (the "Proposed
Disposition") such Units or Underlying Shares (the "Disposition Securities") to
a third party (the "Purchaser"), unless, prior to such Proposed Disposition,
such Contributor Party shall have promptly reduced the terms and conditions, if
any, of the Proposed Disposition to a reasonably detailed writing and shall have
delivered written notice (the "Disposition Notice") of such Proposed Disposition
to CRLP. All offers to purchase Contributor Units or Underlying Shares must be
for cash. The Disposition Notice shall contain an irrevocable offer to sell all,
but not less than all, the Disposition Securities to CRLP upon the same terms
(including price) and subject to the same conditions, if any, as those
contemplated by the Proposed Disposition, and shall be accompanied by a true and
correct copy of the agreement embodying the terms and conditions, if any, of the
Proposed Disposition (which shall identify the Purchaser, the Disposition
Securities, the consideration and method of payment contemplated by the Proposed
Disposition and all other terms and conditions, if any, of the Proposed
Disposition).
<PAGE>

         17.3 CRLP shall have the irrevocable right and option (the "Purchase
Option"), within five (5) business days after receipt of the Disposition Notice
(the "Notice Period"), to accept such irrevocable offer to purchase the
Disposition Securities which are subject to the Proposed Disposition. If CRLP
determines to exercise such Purchase Option, it shall deliver to the Contributor
Party written notice of the exercise of its Purchase Option with respect to the
Disposition Securities (an "Exercise Notice") prior to the expiration of the
Notice Period.

         17.4 If CRLP shall have timely delivered its Exercise Notice with
respect to the Disposition Securities, all certificates for the Disposition
Securities shall be delivered to CRLP at a closing to be held on the later of
the date on which the Proposed Disposition, if accepted, would close or five (5)
business days after such Exercise Notice is given, at the offices of Pryor,
Cashman, Sherman & Flynn located at 410 Park Avenue, New York, New York 10022.
At such closing, CRLP shall deliver to the Contributor Party in immediately
available funds the amount of the purchase price set forth in the Disposition
Notice due against the simultaneous delivery of certificates representing the
Disposition Securities so disposed of, duly endorsed in blank or accompanied by
a stock power or powers duly endorsed in blank, and in proper form for transfer,
together with any necessary stock-transfer stamps, and such Disposition
Securities shall be delivered free and clear of all liens, security interests
and encumbrances whatsoever.

         17.5 If CRLP (i) notifies the Contributor Party that it is not
exercising its Purchase Option or (ii) does not deliver an Exercise Notice prior
to the expiration of the Notice Period, CRLP shall be deemed to have waived its
Purchase Option in which event Contributor Party may sell the Disposition
Securities to the Purchaser for a period of thirty (30) days after the
expiration of the Notice Period in which event the transferee shall take free
and clear of the restrictions set forth in this Section 17; provided, however,
that such Disposition Securities are sold to the Purchaser at a price not less
than that contained in the Disposition Notice and on terms and conditions, if
any, not more favorable to the Purchaser than those contained in the Disposition
Notice. If Contributor Party wishes to sell all or any part of the Disposition
Securities on terms more favorable to the Purchaser than those set forth in the
Disposition Notice or does not sell such Disposition Securities on the terms and
conditions contained in the Disposition Notice within the aforementioned thirty
(30) day period, it shall again be obligated to make new offers to CRLP, in
accordance with this Section 17, before it shall be permitted to consummate a
Proposed Disposition of the Disposition Securities, or any part
<PAGE>

thereof, in a privately negotiated transaction.


18. TAX MATTERS.

         18.1 Contributor will pay or provide for payment of all Taxes due and
payable on or after the Closing and will file all returns and reports required
to be filed on or after the Closing with respect to Taxes imposed in connection
with the ownership and operation of the Property for all taxable periods (or
portions thereof) ending on or prior to the Closing, for which CRLP could be
held liable on a claim made against CRLP.

         18.2 Contributor shall pay any and all Taxes including, without
limitation, Taxes imposed with respect to the ownership or operation of the
Property for all taxable periods (or portions thereof) ending on or prior to the
Closing, imposed upon CRLP based, in whole or in part, upon the failure to
comply with the bulk sales laws.

         18.3 The provisions of this Section shall survive the Closing Date.


19. MANAGEMENT OF THE PROPERTY POST CLOSING.

         19.1 Contributor or its designee shall continue to manage the on-site
day-to-day operations of the Real Property for a period of six (6) months
following the Closing provided, however, that (a) CRLP shall have the right to
terminate Contributor's obligation to operate and manage the Real Property at
any time with cause (including, without limitation, if Winn Thompson is no
longer active in the day-to-day management of the Property) without penalty by
giving written notice of such termination to Contributor, (b) Contributor's
obligations shall include all obligations typically performed by an on-site
manager of real property similar to the Real Property in the location where the
Real Property is located, (c) Contributor shall in all cases act in accordance
with the direction of CRLP, and (d) Contributor or its designee shall enter into
a management agreement substantially in the form annexed hereto as Schedule 19.1
(the "Management Agreement"). During the period Contributor shall act as
manager, Contributor and CRLP shall work together to effect a smooth transition
to management of the Real Property by CRLP or its designee. Notwithstanding the
foregoing provisions of this Section, it is understood and agreed that CRLP
shall assume all billing and accounting responsibilities for the Real Property
as of
<PAGE>

the Closing Date. The provisions of this Section shall survive the Closing.
Notwithstanding anything to the contrary, Contributor covenants that Winn
Thompson shall at al times remain active in the day-to-day management of the
Property pursuant to the Management Agreement.


20. PUBLICATION; CONFIDENTIALITY.

         20.1 CRLP shall have the right to make such public announcements or
filings with respect to the exchange as CRLP may deem reasonably prudent. CRLP
shall not, however, issue any such announcement without the prior reasonable
written approval of Contributor as to the text of the announcement.
Notwithstanding the foregoing, CRLP and Contributor shall be entitled to make
such filings or announcements upon advice of counsel as may be necessary or
required by law.

         20.2. Without the prior written consent of the other party, until CRLP
shall make a public announcement as provided in Section 20.1, neither CRLP nor
Contributor shall disclose, and Contributor and CRLP will direct their
respective representatives, employees, agents and consultants not to disclose,
to any person or entity the fact that CRLP and Contributor have entered into an
agreement to acquire the Property or any of the terms, conditions or other facts
with respect to this Agreement. Notwithstanding the foregoing, either party may
disclose those terms and conditions which are required to be disclosed pursuant
to law or in order to comply with this Agreement; provided, however, that the
disclosing party shall use its best efforts to limit the disclosure to the
information necessary, shall advise any party to whom disclosure is made that
said terms and conditions are subject to a confidentiality requirement and shall
obtain the agreement of said party to keep any information disclosed to it as
confidential. In the event of a breach of the provisions of this Section 20.2,
either party shall be entitled to all of its rights and remedies at law or in
equity.

         20.3 Contributor shall not disclose to any third party any information
that is not public information concerning Cali, CRLP or any transaction or
potential transaction Contributor may become aware of involving Cali or CRLP
without CRLP's prior written consent.


21. REMEDIES.
<PAGE>

         21.1 In the event CRLP or Cali fail to perform their respective
obligations on the Closing Date, CRLP's sole liability, and Contributor's sole
recourse, shall be limited to the amount of the Deposit. Contributor agrees that
retention of the Deposit constitutes fixed and liquidated damages resulting from
CRLP's or Cali's default, and Contributor waives any other claim, at law or in
equity, either against CRLP, Cali or against any person, known or unknown,
disclosed or undisclosed.

         21.2 In the event of any default on the part of Contributor or
Contributor's failure to comply with any representation, warranty or agreement
in any material respect, CRLP shall be entitled to either (i) terminate this
Agreement upon notice to Contributor, in which event neither party shall
thereafter have any further obligations under this Agreement; or (ii) to
commence an action against Contributor seeking specific performance of
Contributor's obligations under this Agreement, in which case the prevailing
party in such action shall be reimbursed for all costs incurred by it
(including, without limitation, reasonable attorney's fees) in connection with
such action. In no event shall Contributor otherwise be liable for any damages
not specifically provided for under this Agreement (including, by way of example
and not limitation, under Section 5.4).

         21.3 The provisions of this Section 21 shall survive the Closing or
earlier termination of this Agreement.

23. ESCROW AGREEMENT.

23.1 The Deposit shall be held by the Escrow Agent in escrow and disposed of
only in accordance with the provisions of this Section. The Deposit shall be
invested in an interest-bearing certificate of deposit, money market fund,
treasury bill or other similar security designated by CRLP, utilizing CRLP's
taxpayer identification number and all interest accruing thereon shall be paid
to CRLP, except as otherwise provided herein.

23.2 The Escrow Agent will deliver the Deposit to Contributor or to CRLP, as the
case may be, under the following conditions:
<PAGE>

(a)  To Contributor on the Closing Date;

(b) To Contributor, together with all interest accruing on the deposit, upon
receipt of written demand therefor, such demand stating that CRLP has defaulted
in the performance of this Agreement and specifically setting forth the facts
and circumstances underlying such default. The Escrow Agent shall not honor such
demand until more than five (5) days have elapsed after the Escrow Agent has
mailed a copy of such demand to Contributor or CRLP, as the case may be, nor
thereafter if the Escrow Agent shall have received written notice of objection
from CRLP in accordance with the provisions of Section 23.3; or

(c) To CRLP upon receipt of written demand therefor, such demand stating that
this Agreement has been terminated in accordance with the provisions hereof, or
Contributor has defaulted in the performance of this Agreement, and specifically
setting forth the facts and circumstances underlying the same. The Escrow Agent
shall not honor such demand until more than five (5) days have elapsed after the
Escrow Agent has mailed a copy of such demand to Contributor or CRLP, as the
case may be, nor thereafter, if the Escrow Agent shall have received written
notice of objection from the other party in accordance with the provisions of
Section 23.3.

23.3 Upon the filing of a written demand for the Deposit by CRLP or Contributor,
the Escrow Agent shall promptly mail a copy thereof to the other party. The
other party shall have the right to object to the delivery of the Deposit by
filing written notice of such objection with the Escrow Agent at any time within
five (5) days after the mailing of such copy to it, but not thereafter. Such
notice shall set forth the basis for objecting to the delivery of the Deposit.
Upon receipt of such notice, the Escrow Agent shall promptly mail a copy thereof
to the party who filed the written demand.

23.4 In the event the Escrow Agent shall have received the notice of objection
provided for in Section 23.2 and within the time therein prescribed, the Escrow
Agent shall continue to hold the Deposit until (a) the Escrow Agent receives
written notice from Contributor and CRLP directing the disbursement of said
Deposit, in which case, the Escrow Agent shall then disburse said Deposit in
accordance with said direction, or (b) in the event of litigation between
Contributor and CRLP, the Escrow Agent shall deliver the Deposit to the Clerk of
the Court in which said litigation is pending, or (c) the Escrow Agent takes
such affirmative steps as the Escrow Agent may, in the Escrow Agent's reasonable
opinion, elect in order to terminate the Escrow Agent's duties including,
<PAGE>

but not limited to, depositing the Deposit with the Court and bringing an action
for interpleader, the costs thereof to be borne by whichever of Contributor or
CRLP is the losing party.

23.5 The Escrow Agent may act upon any instrument or other writing believed by
it in good faith to be genuine and to be signed and presented by the proper
person and it shall not be liable in connection with the performance of any
duties imposed upon the Escrow Agent by the provisions of this Agreement, except
for damage caused by the Escrow Agent's own negligence or willful default. The
Escrow Agent shall have no duties or responsibilities except those set forth
herein. The Escrow Agent shall not be bound by any modification of this
Agreement, unless the same is in writing and signed by CRLP and Contributor,
and, if the Escrow Agent's duties hereunder are affected, unless the Escrow
Agent shall have given prior written consent thereto. In the event that the
Escrow Agent shall be uncertain as to the Escrow Agent's duties or rights
hereunder, or shall receive instructions from CRLP or Contributor which, in the
Escrow Agent's opinion, are in conflict with any of the provisions hereof, the
Escrow Agent shall be entitled to hold the Deposit and may decline to take any
other action.

                  26. RESTRUCTURE.

                  26.1 Contributor, CRLP and Cali agree to consider, in good
faith, a restructuring of this transaction and an amendment to this Agreement

RECITALS

A. Contributor, CRLP and Cali are parties to that certain Contribution and
Exchange Agreement dated as of the date of this Agreement (the "CEA"). The
Thompson Group and the POALP Group are the sole members of Contributor.

         B. Section 26 of the CEA provides, inter alia, that the parties thereto
would consider, in good faith, a Restructure (as such term is defined therein),
and the parties hereto desire to set forth the terms and conditions of the
Restructure and otherwise amend the Agreement upon, and subject to, the terms,
covenants and conditions herein contained.

         C. All capitalized terms used herein shall have the respective meanings
ascribed to them in the CEA unless otherwise indicated.
<PAGE>

         NOW, THEREFORE, in consideration of the mutual promises hereinafter set
forth and for Ten Dollars ($10.00) and other good and valuable consideration,
the mutual receipt and legal sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound hereby, do hereby agree to amend
the CEA as follows:

         1. RESTRUCTURE.

         1.1 The Thompson Group and the POALP Group shall, prior to Closing,
cause Contributor to be dissolved and its assets (including, without limitation,
the Property) and liabilities (including, without limitation, the liabilities
under the CEA) to be distributed in accordance with the terms of a separate
agreement. At the Closing, the Thompson Group and the POALP Group shall each
cause their respective interests in the Property to be sold, assigned,
transferred and conveyed to CRLP in accordance with the terms, covenants and
conditions of the CEA as amended hereby. The Thompson Group and the POALP Group
are jointly and severally bound by all of the terms, covenants and conditions
set forth in the CEA, and they jointly and severally assume the obligations and
liabilities of Contributor set forth in the CEA as amended hereby, as though the
Thompson Group and the POALP Group were parties to the CEA instead of
Contributor.

         1.2 Notwithstanding the provisions of Section 2.1 of the CEA to the
contrary, CRLP shall cause (i) the $21,581,500.00 Cash Payment (subject to
adjustment as provided for under the CEA) to be paid at Closing as follows: (a)
$_________________ to the Thompson Group, and (b) $_________________ to the
POALP Group, by wire transfer of federal funds to an account designated by each
party, and (ii) the Contributor Units to be issued to Unitholders designated by
the POALP Group as set forth on Schedule 1.2 attached hereto.

         2. REPRESENTATIONS AND WARRANTIES.

         2.1 The Thompson Group and the POALP Group each hereby warrant and
represent the following:

         (a) The Thompson Group and the POALP Group are each duly organized and
validly existing limited partnerships organized under the laws of the State of
New Jersey and duly authorized to transact business in the State of New Jersey,
have all requisite power and authority to execute and deliver this Agreement and
all other documents and instruments to be executed and delivered hereunder, and
to perform their respective obligations hereunder and under
<PAGE>

such other documents and instruments in order to sell the Property in accordance
with the terms and conditions hereof. All necessary actions of the partners of
the Thompson Group and the POALP Group to confer such power and authority upon
the persons executing this Agreement and all documents which are contemplated by
this Agreement on their behalf have been taken.

         (b) This Agreement, when duly executed and delivered, will be the
legal, valid and binding obligation of the Thompson Group and the POALP Group,
enforceable in accordance with the terms of this Agreement. The performance by
the Thompson Group and the POALP Group of their respective duties and
obligations under this Agreement and the documents and instruments to be
executed and delivered by them hereunder will not conflict with, or result in a
breach of, or default under, any provision of any of the respective
organizational documents of either the Thompson Group or the POALP Group 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 either party is a party or by which its assets are or may be bound.

         (c) Neither the Thompson Group nor the POALP Group have made a general
assignment for the benefit of creditors, filed any voluntary petition in
bankruptcy or suffered the filing of any involuntary petition by its creditors,
suffered the appointment of a receiver to take possession of all, or
substantially all, of its assets, suffered the attachment or other judicial
seizure of all, or substantially all, of its assets, admitted in writing its
inability to pay its debts as they come due or made an offer of settlement,
extension or composition to its creditors generally.

The provisions of Section 5.4 of the CEA shall apply to the representations and
warranties of the Thompson Group and the POALP Group set forth in this Section
2.1, and the Thompson Group and the POALP Group shall each be individually
liable for the obligation to indemnify, defend and hold Cali and CRLP harmless
from any breach, inaccuracy or incompleteness by such party of a representation
or warranty made by such party contained in this Section 2.1 to the extent
provided for in Section 5.4 of the CEA. Notwithstanding the foregoing, however,
except as provided in Section 2.2 of this Agreement, the Thompson Group and the
POALP Group shall each be jointly and severally liable for the obligation to
indemnify, defend and hold Cali and CRLP harmless from any breach, inaccuracy or
incompleteness of the representations and warranties of the Contributor
contained in the CEA, and the aggregate liability of the Thompson Group and the
POALP Group under Section 5.4 of the CEA shall be $250,000.00 as provided
therein.
<PAGE>

         2.2 The representations and warranties set forth in Section 5.2 of the
CEA shall be deemed to be made by and on behalf of the POALP Group and the
Unitholders, and the Thompson Group shall have no liability to Cali or CRLP for
any breach, inaccuracy or incompleteness thereof. Notwithstanding anything to
the contrary contained in Section 5.4 of the CEA, the representations and
warranties of POALP and the Unitholders contained in Section 5.2 shall survive
the Closing Date indefinitely and shall not be subject to the $250,000.00
limitation of monetary liability provided for in Section 5.4 of the CEA.

         2.3 The Thompson Group shall maintain its existence for a period of six
(6) months after the Closing Date or, if a claim is made by Cali or CRLP
pursuant to the terms of Section 5.4 of the CEA (as amended hereby), the
Thompson Group shall maintain its existence for such longer period of time as
may be necessary for Cali or CRLP to prosecute its claim to completion and, if
it is successful in such proceeding, to obtain and collect the value of its
claim. The provisions of this Section 2.3 shall survive the Closing.

         3. LIMITED GUARANTY OF THE POALP GROUP.

3.1 In order to assist the Unitholders in deferring the recognition of gain for
Federal income tax purposes resulting from the contribution of the Real Property
to CRLP, at Closing, or at any time subsequent thereto in accordance with the
terms hereof, CRLP and its subsidiaries and affiliates will permit the Unit
Holders to guarantee or indemnify CRLP or Cali for a portion of any debt
incurred by CRLP or Cali or their affiliates and/or their subsidiaries
(collectively the "Cali Debt") in the aggregate amount of up to $2,000,000.00
(the "POALP Debt Amount"). CRLP, Cali and their subsidiaries and affiliates
agree to use commercially reasonable efforts, to the extent possible, to
maintain a sufficient amount of liabilities to permit the Unitholders to
guarantee or indemnify, as the case may be, the POALP Debt Amount in order to
allow the Unitholders to continue to defer recognition of gain for Federal
income tax purposes. CRLP and Cali agree to take any and all reasonable actions
necessary for the execution of each guarantee, indemnity, security or pledge
agreement by the Unitholders to result in basis for the Unitholders for Federal
income tax purposes.

         3.2 Notwithstanding the foregoing provisions of Section 3.1, it is
expressly understood and agreed that CRLP, Cali and their subsidiaries and
affiliates have prior and present commitments to maintain a certain amount of
liabilities (approximately
<PAGE>

$530,000,000.00) and that they may in the future, from time to time, make
additional commitments for the same in connection with the issuance of
additional Units in exchange for other properties to unrelated third parties in
tax deferred transactions (collectively, the "Other Groups") and, if so, the
aggregate amount of debt for such Other Groups is referred to herein as the
"Other Debt Amounts." CRLP and Cali will use their commercially reasonable
efforts to maintain, to the extent possible, an amount of liabilities in excess
of the Other Debt Amounts to enable the Unitholders to continue to guarantee or
indemnify a portion of the Cali Debt up to the POALP Debt Amount in order to
maintain for their tax position deferring gain present that results from the
contribution of property to CRLP, provided that CRLP or Cali is not adversely
affected. In this regard, the Unitholders agree to readjust the amounts of their
guarantees and indemnities, and CRLP, Cali and their subsidiaries and affiliates
agree to use commercially reasonable efforts to structure its financing, in such
a way to permit the Unitholders to restructure their respective guarantees or
indemnities so that the re-computed POALP Debt Amounts maintain the deferral of
Federal income taxes.

         4. RESTRICTIONS ON SALE OF THE PROPERTY

4.1 From the period (the "Restricted Period") that commences on the Closing Date
and ends upon the earlier of the date upon which the original Unitholders
"Intended Transferee's" (as defined below) have transferred, sold or otherwise
disposed of ninety-eight (98%) percent or more of their Units in a taxable
transaction or any other transaction which results in a basis step-up to the
Unitholders in the Units to their current fair market value, to other than
Permitted Designees, or (c) the third (3rd) anniversary of the Closing, CRLP,
Cali and their subsidiaries and affiliates may not dispose of or distribute the
Real Property at any time except (i) in a tax-free like-kind exchange which
satisfies the requirements of Code Section 1031 and the Treasury Regulations
promulgated thereunder, (ii) if a sale or disposition of the Real Property would
not result in recognition of Built-in Gain by the Unitholders, (iii) otherwise
in compliance with the provisions of this Section 4, or (iv) if CRLP pays to the
Unitholders an amount equal to the sum of (A) the federal, state, and local
income taxes payable by the Unitholders resulting from the recognition of the
Built-in Gain triggered by such sale, and (B) an additional payment in an amount
equal to the amount such that after payment by the Unitholders of all taxes
(including interest or penalties) on amounts received under Section 4.1 (iv)(A)
and this Section 4.1 (iv)(B), the Unitholders retain an amount equal to the
amount described in Section 4.1(iv)(A). After the Restricted Period, the
<PAGE>

restrictions contemplated by this Section 4 shall terminate in their entirety.
"Permitted Designees" shall include any inter vivos transfer to (i) spouses of
the Intended Transferees, or (ii) any trusts or other entities in which they own
an interest unless any such transfers trigger Built-in Gain or result in a basis
step-up to the Unitholders. For purposes of this Section 4.1, unless CRLP is
furnished with an opinion of counsel to the contrary, any transfer of the Units
to any person or entity other than a Permitted Designee is presumed to be a
taxable transaction. The Unitholders agree to cooperate with CRLP and Cali
regarding the calculation of the amount of actual Built-in Gain attributable to
the Real Property recognized upon any transfer. For purposes of this Agreement,
the term "Built-in Gain" for the Real Property shall mean the excess, if any, of
the fair market value of the Real Property on the Closing Date over the Real
Property's basis for Federal income tax purposes on such date. The provisions of
this Section 4.1 shall survive the Closing. The "Intended Transferee's" shall
mean the beneficial owners of the Unitholders, John Daltner, Estate of Edward R.
Purcell and Troast Overlook Associates.

4.2 Notwithstanding Section 4.1 above, during the Restricted Period, CRLP, Cali
and their subsidiaries and affiliates may dispose of the Real Property at any
time in connection with (i) the sale of all or substantially all of the
properties owned by CRLP under such terms and conditions which the Board of
Directors of Cali (the "Board"), in its sole judgment, determines to be in the
best interests of Cali and its public stockholders, or (ii) a sale (including
without limitation a transfer to a secured lender in lieu of foreclosure) which
the Board, in its sole judgment, determines is reasonably necessary (1) to
satisfy any material unsecured debt, judgment or liability of CRLP or Cali when
they become due (at maturity or otherwise) or (2) to cure any default under any
material mortgage, debt or liability with respect to the Real Property provided,
however, that no such sales will be made under clause (ii) unless CRLP is unable
to settle or refinance any such debts, judgments or liabilities or cure any such
defaults after making commercially reasonable efforts to do so under then
prevailing market conditions. If the Board, in its sole judgment, determines
that it is necessary to dispose of properties to satisfy a material unsecured
debt, judgment or liability of CRLP when it becomes due (at maturity or
otherwise), CRLP covenants and agrees that it shall use commercially reasonable
efforts to sell properties other than the Real Property to satisfy such material
debt, judgment or liability. If, after the Cali has made commercially reasonable
efforts to sell only properties other than the Real Property, an unsatisfied
portion of such debt, judgment or liability remains, CRLP may sell the Real
Property as necessary to
<PAGE>

satisfy fully the remaining unpaid portion. In the case of any disposition of
the Real Property pursuant to this Section 4.2, the Unitholders may attempt to
obtain title to the Real Property so long as any equity in the Real Property
which CRLP may otherwise be seeking to preserve is not lost or jeopardized.
Moreover, in the event of a transfer of the Real Property to a secured lender in
lieu of foreclosure, CRLP shall use commercially reasonable efforts to provide
the Unitholders the right to (a) cure the default, (b) acquire the Real Property
from the lender subject to the debt or liability, or (c) permit the Unitholders
to exercise CRLP's right of redemption with respect to the Real Property.

4.3 After the expiration of the Restricted Period, CRLP, Cali or their
subsidiaries or affiliates may dispose of the Real Property at any time
provided, however, that CRLP, Cali and their subsidiaries and affiliates shall
use commercially reasonable efforts (without cost, liability or expense to CRLP,
Cali or their subsidiaries or affiliates) to prevent any such sale, transfer or
other disposition of the Real Property from resulting in the recognition of
Built-in-Gain by Unitholders.

         4.4 In the event CRLP desires to sell or otherwise desires to dispose
of, or receives an offer to purchase, the Real Property pursuant to Section 4.2
or 4.3 above, CRLP shall give notice (the "Offering Notice") thereof to the
Unitholders. The Offering Notice shall specify the nature of the sale, and the
consideration and other material terms upon which it intends to undertake such
sale. Within ten (10) days thereafter, the Unitholders may elect, by notice to
CRLP, to purchase the Real Property. If the Unitholders elect to so purchase,
then such purchase shall be consummated on the terms and conditions set forth in
the Offering Notice. Unitholders may use their Units as currency, in whole or in
part, in connection with the purchase of any of the Real Property from CRLP
pursuant to this Section 4.4. If within the ten (10) day period during which the
Unitholders have the right to elect to purchase the Real Property for sale under
the Offering Notice, Unitholders do not make the election or fail to respond to
the Offering Notice, then CRLP may undertake to sell the Real Property on such
terms and conditions as it shall elect.

5. CEA REMAINS BINDING. Except as and to the extent modified hereby, the CEA
shall remain in full force and effect and binding upon the parties in accordance
with its terms.

Title and Survey Objections.

     8.1. Buyer shall have until 5:00 p.m. CST on the tenth (10th) business day
          after delivery to Buyer of the Survey and Commitment, within which to
          approve or disapprove all items, including the information reflected
          therein, in the Commitment and the Survey (any such objections being
          the "Title and Survey Objections"), such approvals or disapprovals to
          be within Buyer's sole discretion (the "Title and Survey Objection
          Period"). If Buyer fails to disapprove any such item by specific
          written notice to Seller and the Title Company within the Title and
          Survey Objection Period, Buyer shall be deemed to have approved such
          item. Buyer is deemed to object to all matters listed on Schedule C of
          the Commitment.

     8.2. If and to the extent that the Commitment is updated for any reason,
          then notwithstanding anything to the contrary contained in this
          Section 8 (but subject to Section 8.5 with respect to any change after
          expiration of Buyer's Examination Period), Buyer shall have three (3)
          business days from its receipt of any update or continuation of the
          Commitment and/or Survey to notify Seller of any objections to any
          items not previously reflected in the Commitment or Survey, as the
          case may be, and such item shall not be deemed to be a Permitted
          Exception unless Buyer shall fail to disapprove of any such matter by
          written notice to Seller and the Title Company within such three (3)
          business day period.

     8.3. Subject to Section 8.5 with respect to any change after expiration of
          Buyer's Examination Period, any exceptions in the Commitment which are
          not objected to by Buyer by the expiration of the Buyer's Examination
          Period, or with respect to any updated Commitment, within three (3)
          business days after Buyer's receipt of same, will be deemed to be
          approved by Buyer and shall constitute the "Permitted Exceptions".

     8.4. If Buyer provides Title and Survey Objections, Seller will use its
          good faith and best efforts to expeditiously cure such Title and
          Survey Objections by the Closing Date; provided, however, Seller shall
          be obligated (a) to cause to be released, on or before the date of
          Closing, any monetary liens or security interests created by, under or
          through Seller (including without limitation, the mortgage payable to
          The Frost National Bank), and ad valorem taxes due on the Property,
          and (b) to cause to be released, on or before the date of Closing,
          liens and security interests created by, under or through third
          parties, but in no event will Seller be obligated to expend or incur
          any expense or liability for such cure for liens or security interests
          created by, through or under third parties in excess of a maximum
          outlay in costs and expenditures of One Hundred Thousand and no/100
          Dollars ($100,000.00). If Seller is otherwise unable to cure any one
          or more of such Title and Survey Objections, such failure shall not be
          an event of default by Seller, but in such event Seller shall notify
          Buyer in writing of such Title and Survey Objections (the "First
          Election Notice"), and request that Buyer waive Buyer's right to
          terminate this Agreement due to such objection(s). Buyer shall
          thereafter have five (5) business days after receipt of the First
          Election Notice within which to waive its termination right or to
          terminate this Agreement.
<PAGE>

          In the event Buyer fails to respond within such five (5) business day
          period, Seller shall deliver a second notice (the "Second Election
          Notice") specifying the Title and Survey Objection and stating that
          Buyer failed to respond to the First Election Notice, and, Buyer will
          be deemed to have waived and accepted the uncured and unsatisfied
          Title and Survey Objections, which shall then become Permitted
          Exceptions (hereinabove defined). If Buyer terminates this Agreement
          under this Section 8, the Initial Earnest Money Payment, less One
          Hundred Dollars ($100.00) to be retained by Seller as consideration
          for this Agreement, and the Earnest Money Deposit will be refunded to
          Buyer and the parties shall have no further obligations under this
          Agreement except as to obligations which specifically are provided in
          this Agreement to survive termination of this Agreement.

     8.5. If and to the extent that there is any change in the Commitment or
          Survey after expiration of Buyer's Examination Period, then in such
          event only, Buyer will have until Closing to notify Seller of any
          objections to any items not previously reflected in the Commitment or
          Survey, as the case may be (the Supplemental Title and Survey
          Objections"), and such item shall not be deemed to be a Permitted
          Exception and Seller shall be obligated to cure such Supplemental
          Title and Survey Objections or item in accordance with Section 8.4,
          above. If Seller fails to cure or satisfy such Supplemental Title and
          Survey Objections prior to Closing (other than as required by Seller
          in Section 8.4, above), Buyer shall be entitled only to either (a)
          waive such objections, in which event Buyer shall be deemed to have
          accepted such uncured and unsatisfied objections (which shall become
          Permitted Exceptions), or (b) terminate this Agreement by written
          notice accordingly from Buyer to Seller at or prior to the Closing
          Date, in which case the Initial Earnest Money Payment, less One
          Hundred Dollars ($100.00) to be retained by Seller as consideration
          for this Agreement, and the Earnest Money Deposit will be refunded to
          Buyer and the parties shall have no further obligations under this
          Agreement except as to obligations which specifically are provided in
          this Agreement to survive termination of this Agreement.

          manner or amount (but not to include any insurance of any Tenant
          insuring such Tenant's leasehold improvements unless a copy of such
          insurance policy is in possession of Seller; or if such insurance is
          otherwise available to Seller under any applicable lease, then upon

          required in this Section 10.1, during normal business hours (and while
          strictly adhering to the confidentiality and nondisclosure provisions
          herein), to enter upon the Property and to conduct soil,
          environmental, structural, mechanical and/or other studies or tests or
          reviews, which Buyer deems advisable, at the expense of Buyer (the
          "Property Inspection"). Buyer (i) shall not permit the Property
          Inspection to be conducted in any manner that creates any materially
          unsafe or hazardous condition on the Property, and (ii) shall not
          permit the Property Inspection to be conducted in any manner that
          unreasonably disturbs, interrupts, or interferes with any persons,
          including, without limitation, Tenants or other occupants of the
          Property, or their employees, customers or invitees. Buyer shall give
          Seller written notice not less than two (2) business days prior to
          conducting any test or inspection that physically affects the
          Property, such as soil borings or internal examination of equipment or
          components of improvements, if any. Buyer shall timely pay all fees
          charged by Buyer's experts and shall not permit any claims to be made
          against Seller or permit any liens to be created against the Property
          by Buyer's experts. The entry upon the Property by Buyer, Buyer's
          personnel and Buyer's experts shall be at their respective risks;
          provided, however, nothing herein shall be deemed to release Seller
          from any liability for its own negligence or willful misconduct. Buyer
          shall have the right, upon not less than two (2) business days prior
          written notice from Buyer to Seller specifically identifying the party
          to be contacted and the information to be obtained, to contact third
          parties regarding the Property, including without limitation, tenants,
          contractors, property managers, parties to Contracts, and municipal,
          local or other governmental officials and representatives.

     10.2.Buyer shall not perform any test or inspection which will permanently
          alter or damage the Property, and at the end of the Buyer's
          Examination Period, Buyer shall at Buyer's sole cost and expense
          restore and replace any part of the Property altered or damaged as a
          result of the Property Inspection, to substantially the condition of
          the Property prior to such studies. Any destructive or invasive
          testing of the Property by Buyer or its
<PAGE>

          agents will be subject to the prior written approval of Seller, and
          Seller will not unreasonably withhold or delay its consent to any such
          testing if there is a reasonable basis to believe that such testing
          may disclose a violation or possible violation of an applicable
          Environmental Law (as hereinafter defined). If Seller withholds its
          consent for any reason, Buyer may terminate this Agreement and in such
          event receive a refund of the Initial Earnest Money Payment less
          $100.00 as independent consideration to Seller, and the Earnest Money
          Deposit and neither Seller nor Buyer will have any further liability
          to or responsibility to the other hereunder other than as provided in
          this Agreement to specifically survive termination of this Agreement.

     10.3.During Buyer's Examination Period, Buyer will review all of the
          Contracts provided by Seller to Buyer, and Buyer will determine to its
          satisfaction whether and with what prior notice each such Contract is
          terminable. Buyer will be responsible at Closing to provide any notice
          of termination, and will otherwise be responsible to assume all
          Contracts from and after Closing until terminated (1) which are
          terminable upon thirty (30) days or less written notice or (2) with
          The City Public Service Board of San Antonio or (3) with BFI. Buyer's
          obligation to close this transaction is subject to the condition that,
          as of the Closing, the Contracts to be assigned to Buyer shall be in
          full force and effect, unmodified, and free from any default in any
          material manner or amount. Buyer will not be obligated to assume any
          Contract if Buyer did not receive a copy of that Contract during the
          Buyer's Examination Period. In any event: (1) any property management
          and leasing agreement must be terminated at Closing; and (2) Buyer
          will not assume any of the agreements pertaining the Athletic Club
          Renovations provided for in Section 21.8, below, and Seller shall
          retain and perform those agreements. Seller will be responsible for,
          and does indemnify Buyer against, any Contract which is not terminable
          in 30 days or less, other than contracts with The City Public Service
          Board of San Antonio and BFI. The provisions of this Section 10.3
          shall survive the Closing.

     10.4.SELLER SHALL NOT BE LIABLE TO BUYER, OR ANY OF BUYER'S PERSONNEL,
          AGENTS OR EXPERTS FOR, AND BUYER AGREES TO RELEASE, INDEMNIFY, DEFEND
          AND HOLD SELLER (AND ITS OFFICERS AND JOINT VENTURE PARTNERS, AND
          THEIR RESPECTIVE OFFICERS, DIRECTORS AND SHAREHOLDERS) HARMLESS FROM
          AND AGAINST ANY CLAIMS BY ANY PERSON FOR INJURY, DAMAGES OR LOSS TO
          PERSONAL PROPERTY RESULTING FROM, INCIDENT TO, OR ARISING OUT OF THE
          CONDUCT OF THE PROPERTY INSPECTION OR THE ENTRY UPON THE PROPERTY BY
          BUYER, BUYER'S PERSONNEL, AGENTS OR EXPERTS, AND FROM ALL
          OUT-OF-POCKET COSTS INCURRED BY SELLER TO DEFEND AGAINST ANY SUCH
          CLAIMS, INCLUDING, WITHOUT LIMITATION, REASONABLE ATTORNEY'S FEES;
          PROVIDED HOWEVER, THIS INDEMNITY SHALL NOT APPLY IF AND TO THE EXTENT
          THAT SELLER'S NEGLIGENCE OR WILLFUL MISCONDUCT IS A CAUSE THEREOF.
<PAGE>

     10.5.BUYER IS ENCOURAGED TO CONDUCT AN INDEPENDENT INVESTIGATION AND
          INSPECTION OF THE PROPERTY, UTILIZING SUCH EXPERTS AS BUYER DEEMS TO
          BE NECESSARY FOR AN INDEPENDENT ASSESSMENT OF THE STRUCTURAL AND
          OPERATIONAL INTEGRITY OF THE IMPROVEMENTS AND EQUIPMENT USED IN THE
          OPERATION OF THE PROPERTY, AND COMPLIANCE OF THE PROPERTY (INCLUDING
          SPECIFICALLY THE IMPROVEMENTS) WITH APPLICABLE LAWS, INCLUDING THE
          FEDERAL AMERICANS WITH DISABILITIES ACT, THE TEXAS ARCHITECTURAL
          BARRIERS ACT, AND/OR APPLICABLE ENVIRONMENTAL LAWS (AS HEREINAFTER
          DEFINED).

     10.6.For purposes of this Agreement, the term "Property Information"
          means: the results and products of the Property Inspection, including,
          without limitation all civil engineering, soil, environmental,
          operational and feasibility inspections, tests and reports thereof of
          the Property and all other information regarding the Property obtained
          by Buyer, including but not limited to the Inspection Items, which
          shall be deemed to be proprietary information belonging to Seller and
          shall be confidential unless and until Buyer acquires the Property
          hereunder, even if such information is obtained at Buyer's expense.
          Prior to Closing, or if Closing shall not occur, then for twenty-four
          (24) months after the Effective Date, Buyer shall not disclose,
          without the prior written consent of the Seller, in its sole
          discretion, any of the Property Information to any person other than
          (i) Buyer's personnel, (ii) Buyer's experts, attorneys, accountants,
          consultants, lenders and equity investors (who in each case shall also

     13.29. If at the Closing the representations provided in this Section 13
          are in any material respect different than the representations
          provided in this Section 13 because of change of circumstances, and if
          such change of circumstances are not a result of a knowing and
          material breach of any representation of Seller under this Section 13,
          then Buyer (as its only remedies) may either (a) waive any such change
          in circumstances and such representations and warranties of Seller
          shall be amended accordingly, or (b) elect to terminate this Agreement
          and receive the return of the Initial Earnest Money Payment, less One

     13.30. If, at the Closing, any representation contained in this Section 13
          is not accurate in any material respect for any reason other than
          changed circumstances which are not a result of a knowing and material
          breach of any representation of Seller (that is, other than as covered
          by Section 13.29, above), Buyer will have the following options only:
          (a) to waive such requirement and proceed with Closing in which case

          in addition to the $100,000 provided above in this Section 13.28) or
          (b) terminate this Agreement and receive the return of the Initial
          Earnest Money Payment and the Earnest Money Deposit, together with all
          other sums, if any, paid on account of this Agreement by Buyer to
          unrelated third-parties, including, without limitation, all amounts
          paid or incurred by Buyer, whether before or after the date of this
          Agreement, in connection with its due diligence investigation of the
          Property, and neither Seller nor Buyer will have any further liability
          to or responsibility to the other hereunder other than as provided in
          this Agreement to specifically survive termination of this Agreement;
          but in no event will Seller be liable to Buyer for any other damages
          (actual, consequential, speculative, punitive, or otherwise).

     13.31. If at or before expiration of Buyer's Examination Period, Buyer
          discovers any matter that would be a breach of a representation
          contained in this Section 13, but for the fact that the representation
          is limited to Seller's knowledge (excluding by reason of changed
          circumstances which is not a result of a knowing and material breach
          of any representation of Seller under this Section 13), then Buyer
          will have the following options only: (a) to waive such requirement
          and proceed with Closing or (b) terminate this Agreement and receive
          the return of the Initial Earnest Money Payment and the Earnest Money
          Deposit and neither Seller nor Buyer will have any further liability

          does hereby agree to indemnify and hold Seller harmless from any
          liability to or claims by any unrelated third-parties arising out of

          for breach of Seller's representations and warranties, the

          qualified by any information with respect to which Buyer has current
          actual knowledge at the Closing.

          to Buyer pursuant to the tenant's Lease. If Seller has collected
          estimates of Additional Rents in excess of a Tenant's proportionate
          share allocable to the period prior to Closing, Buyer shall receive a
          credit against the Purchase Price at Closing for any such excess.

     17.5.Seller shall cooperate with Buyer in all respects in connection with
          the collection of rents and Additional Rents, so long as Seller shall
          incur no liability or significant expenses in doing so. In particular,
          Seller shall for a period to not exceed thirty (30) days after
          Closing, cooperate with Buyer in calculating Additional Rents and
          billings therefor.

     17.6. The provisions of this Section 17.2 through 17.5 shall survive the
          Closing.

     17.7.If any of the items subject to apportionment under the foregoing
          provisions of this Section 17 cannot be apportioned at the Closing
          because of the unavailability of the information necessary to compute
          such apportionment, or if any errors or omissions in computing
          apportionments at the Closing are discovered subsequent to the
          Closing, then such item shall be reapportioned and such errors and
          omissions corrected as soon as practicable after the Closing Date and
          the proper party reimbursed, which obligation shall survive the
          Closing for a period of one hundred eighty (180) days after the
          Closing Date as hereinafter provided. Neither party hereto shall have
          the right to require a recomputation of a Closing apportionment or a
          correction of an error or omission in a Closing apportionment unless
          within the aforestated one hundred eighty (180) day period one of the
          parties hereto (i) has obtained the previously unavailable information
          or has discovered the error or omission, (ii) has given notice thereof
          to the other party, together with a copy of its
<PAGE>

          good faith recomputation of the apportionment and copies of all
          substantiating information used in such recomputation and (iii) such
          recomputation or correction involves amounts which in the aggregate
          exceed Five Thousand Dollars ($5,000). The failure of a party to
          obtain any previously unavailable information or discover an error or
          omission with respect to an item subject to apportionment hereunder
          and to give notice thereof as provided above within one hundred eighty
          (180) days after the Closing Date shall be deemed a waiver of its
          right to cause a recomputation or a correction of an error or omission
          with respect to such item after the Closing Date.

     17.8.Buyer shall receive a credit on the Closing Date equal to all leasing
          commissions due to leasing or other agents for the current remaining
          term of each Lease (determined without regard to any unexercised
          termination or cancellation right), discounted to present value using
          reasonable discount rates. Buyer shall assume, in writing, the
          obligation to pay any such leasing commissions due thereunder after
          the Closing Date up to the amount of such credit (without discount).
          Buyer shall promptly return to Seller any such commission (without
          discount) that, due to later events, does not become due and payable.
          At Closing, Buyer shall assume leasing commissions for renewals or
          expansions under any Lease expressly identified in the Project Rent
          Roll as a result of the exercise of such right after the Effective
          Date of this Agreement. If by Closing Seller has not completed and
          paid in full all tenant improvement expenses, tenant allowances,
          moving expenses and other out-of-pocket costs which are the obligation
          of Landlord under Leases ("TI Obligations"), other than for the
          Athletic Club Tenant for which the provisions of Section 21.8 shall
          apply, then such costs as reasonably agreed by Buyer and Seller shall
          be withheld from the Purchase Price at Closing, placed in escrow with
          the Title Company, and Buyer shall be responsible for completing and
          paying such TI Obligations. Any funds held in the escrow shall be
          released to Buyer without any requirement for the consent of Seller
          and shall be used by Buyer to pay the Landlord's share of such tenant
          improvement and allowances. If there are any funds remaining in escrow
          after payment of such TI Obligations, such excess shall be paid to
          Seller; but if the amount in escrow is insufficient for the purpose,
          Seller shall reimburse Buyer for such deficiency on demand.
          Notwithstanding the above, Buyer will be responsible for Commission
          (not to exceed $11,616.00) and Leasehold Allowances (but not to exceed
          $14,040.00) on the Fireman's Fund Lease Agreement.

18.  Assessments. If, on the Closing Date, the Property or any part thereof
     shall be affected by any assessment or assessments which are or may become
     payable in installments, of which the first installment is now or at
     Closing will be a charge or lien, or has been paid, then for the purposes
     of this Agreement, all the unpaid installments of any such assessment
     including those which are to become due and payable on or after the Closing
     Date shall be deemed to be due and payable and be liens upon the Property
     and the payment thereof shall be paid and discharged by Seller upon the
     Closing.

19.  Closing Costs. Notwithstanding anything to the contrary contained herein,
     the Closing Costs
<PAGE>

     shall be paid as follows:

     19.1. By Seller:

         (a) Title insurance examination and premium; (b) Preparation of Special
         Warranty Deed; (c) Revenue stamps or transfer tax, if any; (d) One-half
         (1/2) the escrow fee, if any; (e) Brokerage fee as outlined in Section
         26 herein; (f) The Survey; Seller's attorneys' fees; and Recording fees
         with regard to releases of liens.

     19.2. By Buyer:

         (a) Preparation of Mortgage, Deed of Trust or other applicable
         financing instruments; (b) Recording fees (except as provided in
         Section 19.1(h), above); (c) One-half (1/2) the escrow fee, if any; (d)
         Any additional engineering reports, environmental reports, appraisals,
         or other
                  reports or studies required by Buyer;
         (e)  The survey deletion fee for Title Insurance purposes; and
         (f)  Buyer's attorneys' fees.

20.  Default.

     20.1.Default of Seller. In the event Seller is in default of its
          obligations under this Agreement, Buyer, as its exclusive remedies,
          shall be entitled to either (a) a refund of the full amount of the
          Initial Earnest Money Payment and the Earnest Money Deposit together
          with all other sums, if any, paid on account of this Agreement by
          Buyer to unrelated third-parties, including, without limitation, all
          amounts paid or incurred by Buyer, whether before or after the date of
          this Agreement, in connection with its due diligence investigation of
          the Property, or (b) enforce specific performance of this Agreement;
          provided, however, that any such action for specific performance shall
          be initiated by Buyer, if at all, within sixty (60) days after that
          date on which the sale of the Property was scheduled to close
          hereunder and, if such action is not initiated within such 60-day
          period, then Buyer shall be deemed conclusively to have elected to
          waive the right to initiate such action for specific performance, in
          which event, Buyer's sole remedy shall be to terminate this Agreement
          and receive a refund of the Initial Earnest Money Payment and the
          Earnest Money Deposit together with all other sums, if any, paid on
          account of this Agreement by Buyer to unrelated third-parties,
          including, without limitation, all amounts paid or incurred by Buyer,
          whether before or after the date of this Agreement, in connection with
          its due diligence investigation of the Property; and provided,
          further, Seller shall not be in default hereunder
<PAGE>

          unless and until Buyer shall provide written notice to Seller of the
          basis for any such default and Seller has failed to cure such matter
          within ten (10) days of its receipt of such notice; provided, further,
          Buyer may not enforce specific performance against Seller if Seller is
          unable to deliver the Property subject only to the Permitted
          Exceptions (e.g., a third party places a cloud on title to the
          Property which Seller cannot remove prior to Closing). In no event
          shall Seller be liable to Buyer for any other actual, punitive,
          speculative, consequential or other damages, excepting only in the
          case of the inability of Seller to deliver the Property subject only
          to the Permitted Exceptions is due to a willful and bad faith overt
          act of Seller. No delay or omission in the exercise of any right or
          remedy accruing to Buyer upon any default of Seller under this
          Agreement shall impair any such right or remedy or be construed as
          waiver of such default or any default theretofore or thereafter
          occurring. The waiver by Buyer of any condition or event of default
          shall not be deemed to be a waiver of any other condition or of any
          prior or subsequent event of default.

     20.2.Default of Buyer. Except as provided below, in the event of a default
          hereunder by Buyer or if Buyer shall otherwise fail to perform any of
          Buyer's obligations hereunder Seller may terminate this Agreement by
          notice to Buyer and may retain the Initial Earnest Money Payment and
          the Earnest Money Deposit as liquidated damages and this shall be
          Seller's sole remedy for the Buyer's breach of this Agreement and
          neither party shall have any further rights, obligations or
          liabilities hereunder, except as otherwise provided herein; however,
          Buyer shall not be in default hereunder unless and until Seller shall
          provide written notice to Buyer of the basis for any such default and
          Buyer has failed to cure such matter within ten (10) days of its
          receipt of such notice. Seller and Buyer agree that it is difficult to
          determine, with any degree of certainty, the loss which Seller would
          incur in the event of Buyer's failure to close the purchase of the
          Property, and the parties have agreed that the amount of the Earnest
          Money Deposit represents a reasonable estimate of such loss and is
          intended as a liquidated damages provision. No delay or omission in
          the exercise of any right or remedy accruing to Seller upon any
          default of Buyer under this Agreement shall impair such right or
          remedy or be construed as a waiver of such default or any default
          theretofore or thereafter occurring. The waiver by Seller of any
          condition or event of default shall not be deemed to be a waiver of
          any other condition or of any prior or subsequent event of default.

21.  Future Operations. From the date of this Agreement until the Closing or
     earlier termination of this Agreement, Seller will:

     21.1.Maintenance and Operation of Property. Keep, operate and maintain the
          Property in substantially the same condition and manner as the
          Property is now maintained and operated by Seller and perform all
          obligations on the part of landlord to be performed under the Lease.

     21.2. Litigation and Claims. Promptly advise Buyer of any actual or
          threatened litigation,
<PAGE>

          arbitration, administrative hearing or claim (of any material matter
          or amount) concerning the Property for which Seller has current actual
          knowledge, or if Seller determines that any representation or warranty
          made by Seller in Section 13 hereof is incorrect in any material
          manner or amount.

     21.3. Insurance. Maintain (or cause the maintenance of) all liability,
          property and casualty or other insurance which Seller currently has in
          force with respect to the Property.

     21.4.No Change in Title. Not enter into or acquiesce in the filing of any
          easement, license, plat (or replat) or zoning charge affecting the
          Property, except as provided in Section 21.9, below, without the prior
          written consent of Buyer in its sole discretion.

     21.5. No Encumbrance. Not transfer or encumber or permit any lien to be
          placed against all or any portion of the Property.

     21.6.No Sale. Neither Seller nor any of its affiliates shall negotiate,
          discuss or enter into any agreement with any third party regarding the
          transfer, sale or conveyance of all or any portion of the Property.

     21.7.Leasing. (i) Not modify any existing Lease or enter into any new
          Lease in any manner without the prior written consent of Buyer, and
          Buyer will not unreasonably withhold or delay its consent for any
          modification to any existing lease or for Seller to enter into any new
          Lease which is with an individual or entity unrelated (directly or
          indirectly) to Seller and/or its joint venture partners and which is
          in the ordinary course of business of the Property consistent with
          past business practices in the operation of the Property, and any such
          consent will be deemed given if specific written objection is not
          provided by Buyer to Seller within five (5) business days after Buyer
          receives written notice of such amendment or new lease, with the
          proposed lease amendment or new agreement attached to such notice; and
          (ii) promptly deliver to Buyer a copy of any notice (including,
          without limitation, a notice of default under any Lease, and promptly
          cure any such default; provided, however, from and after expiration of
          Buyer's Examination Period, Buyer may withhold its consent in its sole
          discretion.

     21.8.Athletic Club Renovations. Pursuant to the Lease for the Athletic
          Club, the Athletic Club Tenant and Seller have entered into certain
          agreements for refurbishment/renovations which are being made to the
          Athletic Club, the cost of which are to be borne equally by Seller, as
          Landlord, and such Tenant. At Closing, Seller will escrow with the
          Title Company, under escrow instructions to be agreed upon between
          Seller and Buyer during Buyer's Examination Period, any then remaining
          obligation of Seller and Tenant for the costs of such improvements
          plus any additional sums reasonably projected to complete such
          refurbishment/renovations; however if the escrowed amount is
          insufficient to complete such refurbishment/renovations, Seller will
          remain liable for any deficiency. Seller will, until completion,
          continue such improvements pursuant to such agreements with such
          changes
<PAGE>

          as Seller in its discretion shall deem appropriate, but Seller will
          notify Buyer in writing of any material change in such planned
          improvements, and any such material change after expiration of the
          Buyer's Examination Period will require the prior written consent of
          Buyer, which consent Buyer will not unreasonably withhold or delay,
          and such consent will be deemed provided if written objection is not
          provided by Buyer to Seller within five (5) business days after Seller
          notifies Buyer in writing of the specific nature of the change
          requested.

     21.9.Described Easements. Seller is in the process of negotiating (i) an
          easement to provide the owner of the tract contiguous to and south of
          the Property (who is an affiliate of Seller) access to the utility
          easements located within the entry drive of Concord Plaza so long as
          any such access is at the sole cost of such owner and has no material
          adverse effect on the capacity of any utilities provided to the
          Property and (ii) acquisition of the parking area on the north side of
          the Property, which is currently owned by an affiliate of Seller and
          provided to Seller by easement. Both such transactions will be
          completed at or before Closing at the expense of Seller. If the
          transaction described in clause (ii) has not been completed at or
          before Closing, Buyer may terminate this Agreement and receive a
          return of the Initial Earnest Money Payment and the Earnest Money
          Deposit, and neither party shall have any further liability to the
          other hereunder other than the obligations which specifically survive
          termination as provided in this Agreement.

     21.10. Claims. Promptly deliver notice to Buyer of, and, if the same may
          adversely affect the Buyer or the Property, defend at the Seller's
          expense, all actions, suits, claims and other proceedings affecting
          the Property, or the use, possession or occupancy thereof;

     21.11. Condemnation. Promptly deliver notice to Buyer of any actual or
          threatened condemnation of the Property or any portion thereof;

     21.12. Permits. Maintain all Permits in full force and effect and promptly

          make all payments and observe and perform all obligations to be paid,
          observed or performed by the Seller thereunder, and promptly notify
          the Buyer of any receipt or delivery of any notice (including any
          notice of default) thereunder, and not modify, amend, renew, extend,
          terminate or otherwise alter any Contracts nor enter into any new
          maintenance service contracts or any other agreements affecting the
          Property without the prior written consent of Buyer in each instance,
          which consent will not be unreasonably withheld or delayed; provided,
          however, Buyer may withhold its consent in its sole discretion for any
          such Contract which cannot be terminable on thirty (30) days notice or
          less.

     21.14. Repairs. Provide all services, repairs and other work required to be

          Personal Property (as defined in Section 1.8, above) of any material
          value or which is material to the operations of the Property unless it
          is replaced with a comparable item of equal quality and quantity as
          existed as of the time of such removal; and

     21.16. Security Deposits. Not apply any of the Security Deposits, whether
          to a default of a Tenant or otherwise without the prior written
          consent of Buyer which consent shall not be unreasonably withheld or
          delayed.

22.  Casualty. The risk of loss or damage to the Property by fire or other
     casualty shall, until Closing, be borne by Seller. After Closing, the risk
     of any loss or damage to the Property by fire or other casualty shall be
     borne by Buyer. Seller shall promptly give Buyer written notice if all or
     any portion of the Property is damaged or destroyed by fire or other
     casualty and the extent thereof. For purposes of this Section 22, "Material
     Casualty" shall be any casualty resulting in damage to the Property of
     Twenty-Five Thousand and No/100 Dollars ($25,000.00) or more or any
     casualty which can be the basis for any Tenant to terminate any Lease or
     Leases which, individually or in the aggregate, is for more than five
     thousand (5,000) square feet of net rentable area in each case as
     reasonably estimated by Buyer. In the event of a Material Casualty, Buyer
     may, by written notice to Seller within ten (10) days after receipt of
     notice of the occurrence of such Material Casualty, elect to cancel this
     Agreement. In the event either party shall so elect, the Initial Earnest
     Money Payment and Earnest Money Deposit shall be returned to Buyer and,
     upon such return of the Initial Earnest Money Payment and the Earnest Money
     Deposit, both parties shall be relieved and released of and from any
     further liability hereunder, except as otherwise provided in this
     Agreement. In the event of a Material Casualty, if this Agreement is not so
     cancelled by Buyer, or if there is a non-material casualty, this Agreement
     shall not be affected, but Seller shall assign to Buyer all of Seller's
     right, title and interest in any insurance proceeds and claims, and the
     Purchase Price shall be reduced by the amount of any applicable insurance
     policy deductible.

23.  Disclaimer Regarding Representations and Warranties of Seller. EXCEPT FOR
     THE WARRANTIES OF TITLE CONTAINED IN THE DEED AND THE LIMITED EXPRESS
     WRITTEN REPRESENTATIONS AND WARRANTIES OF SELLER CONTAINED IN SECTION 13
     HEREOF, BUYER ACCEPTS THE PROPERTY "AS IS" AND "WHERE IS", WITH ALL FAULTS,
     AND BUYER AGREES THAT, EXCEPT AS EXPRESSLY PROVIDED HEREIN, NEITHER SELLER
     NOR ANY OF SELLER'S EMPLOYEES, OFFICERS, DIRECTORS, REPRESENTATIVES OR
     AGENTS (COLLECTIVELY THE "SELLER RELATED PARTIES") HAVE MADE OR GIVEN ANY
     WARRANTIES, GUARANTEES, OR REPRESENTATIONS OF ANY KIND WHATSOEVER,
     REGARDING ANY MATTER RELATING TO THIS AGREEMENT OR THE PROPERTY, WHETHER
     ORAL OR WRITTEN, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, BUYER
     AGREES THAT THERE ARE NO EXPRESS OR IMPLIED WARRANTIES OF HABITABILITY,
     MERCHANTABILITY, SUITABILITY, OR FITNESS FOR A
<PAGE>

     PARTICULAR PURPOSE AND THAT THERE ARE NO EXPRESS OR IMPLIED WARRANTIES OR
     REPRESENTATIONS REGARDING THE PRESENT OR FUTURE VALUE, PROFITABILITY,
     PERFORMANCE OR PRODUCTIVITY OF THE PROPERTY, OR REGARDING THE PAST OR
     PRESENT COMPLIANCE BY SELLER OF ENVIRONMENTAL LAWS.

24.  Condemnation. If, prior to Closing, all or any portion of the Property is
     condemned or taken by eminent domain by any authority (a "Condemnation"),
     Seller shall promptly notify Buyer thereof, and Buyer may terminate this
     Agreement by giving written notice thereof to Seller prior to the Closing
     Date, in which event the Initial Earnest Money Payment and the Earnest
     Money Deposit shall be returned to Buyer and, upon the return of such
     Initial Earnest Money Payment and the Earnest Money Deposit, both parties
     shall be relieved and released of and from any further liability hereunder,
     except as otherwise provided in this Agreement. If Buyer does not elect to
     terminate this Agreement as a result of a Condemnation, Seller shall pay to
     Buyer, at Closing, all awards or other proceeds for such Condemnation
     collected by Seller and assign and transfer to Buyer all of Seller's right,
     title and interest in and to any claims for uncollected awards and other
     proceeds for such Condemnation which Seller may be entitled to receive. At
     Buyer's request, from and after the Closing, Seller shall cooperate with
     Buyer in the settlement of any condemnation claims pursued by Buyer.

     of any resolution or settlement of any such claim, and the Indemnified
     Party shall have the right to approve any such resolution or settlement
     only if such resolution or settlement is likely to have a material adverse
     effect upon the Indemnified Party (e.g., potential further liability to the
     Indemnified Party which may not be covered by the Indemnifying Party), in
     which case such approval is required but may not be unreasonably withheld
     or delayed.

     Agreement, the prevailing party shall be entitled to reasonable attorney's
     fees and costs.

     Examination Period, to secure Seller's obligations hereunder, which Escrow
     shall terminate on the expiration of the Claim Period (as defined in

<PAGE>

         3. Deleted prior to execution.

         4. TITLE MATTERS TO WHICH THIS SALE IS SUBJECT.

                  4.1 The Property is to be contributed to Purchaser subject to
the following (collectively, the "Permitted Encumbrances"):

                           (a)  The lien of real estate taxes, personal
property taxes, water charges, and sewer charges provided same
are not due and payable, but subject to adjustment as provided
herein;

                           (b)  The rights of Tenants, as tenants only;

                           (c)  Those restrictions, covenants, agreements,
easements, matters and things affecting title to the Real Property and more
particularly described in Schedule 4.1(c) annexed hereto and by this reference
made a part hereof;

                           (d)  Any and all laws, statutes, ordinances,
codes, rules, regulations, requirements, or executive mandates affecting the
Property as of the date hereof except for engineering or institutional controls,
including without limitation, a deed notice or declaration of environmental
restrictions, a groundwater classification exception area or well restriction
area affecting the Property; and

                           (e)  The state of facts shown on the survey, if
any, described on Schedule 4.1(c), and any other state of facts which a recent
and accurate survey of the Real Property would actually show, provided same does
not impair the use of the Real Property as intended by Purchaser and does not
render title uninsurable at standard rates.

                  4.2 Purchaser shall cause any title company licensed to do
business in the State of Connecticut (the "Title Company") to prepare a title
insurance search and commitment for an owner's title insurance policy for the
Real Property (the "Title Commitments") and shall cause a copy of same to be
delivered to counsel for Seller. If any defects, objections or exceptions in the
title to the Real Property appear in the Title Commitments (other than the
Permitted Encumbrances) which Purchaser is not required to accept under the
terms of this Agreement, Seller agrees to use good faith efforts to cure same
prior to Closing (as defined in Section 10) and in any event to cure, at its
expense, (i) judgments against Seller, (ii) mortgages and other
<PAGE>

liens which can be satisfied by payment of a liquidated amount and (iii)
defects, objections or exceptions which can be removed by payments not to exceed
three (3%) percent of the Purchase Price in the aggregate. Seller, in its
discretion, may adjourn the Closing for up to sixty (60) days in order to
eliminate unacceptable defects, objections or exceptions. If, after complying
with the foregoing requirements, Seller is unable to eliminate all unacceptable
defects, objections or exceptions in accordance with the terms of this Agreement
on or before such adjourned date for the Closing, Purchaser shall elect either
(w) to terminate this Agreement by notice given to the Seller, in which event
the provisions of Section 4.7 shall apply, or (x) to accept title subject to
such unacceptable defects, objections or exceptions and receive no credit
against or reduction of the Purchase Price. Seller agrees and covenants that it
shall not voluntarily place any defects, objections or exceptions to title to
any of the Real Property from and after the date of the first issuance of the
Title Commitment for said Property.

                  4.3 It shall be a condition to Closing that Seller convey, and
that the Title Company insure, title to the Real Property in the amount of the
Purchase Price (at a standard rate for such insurance) in the name of Purchaser
or its designees, after delivery of the Deed (as defined in Section 10), by a
standard 1992 ALTA Owners Policy, with such ALTA endorsements as may be
available and as required by Purchaser, free and clear of all liens,
encumbrances and other matters, other than the Permitted Encumbrances (the
"Title Policy"). The Title Company shall provide affirmative insurance that any
(i) Permitted Encumbrances have not been violated, and that any future violation
thereof will not result in a forfeiture or reversion of title; (ii) Purchaser's
contemplated use of the Property will not violate the Permitted Encumbrances;
and (iii) the exception for taxes shall apply only to the current taxes not yet
due and payable. Seller shall provide such affidavits, including title
affidavits and survey affidavits of no change, and undertakings as the Title
Company insuring title to the Property may require. The words "insurable title"
and "insurable" as used in this Agreement are hereby defined to mean title which
is insurable at standard rates (without special premium) by the Title Company
without exception other than the Permitted Encumbrances, and standard printed
policy and survey exceptions.

                  4.4 Any unpaid taxes, water charges, sewer rents and
assessments, together with the interest and penalties thereon to a date not less
than seven (7) business days following the Closing Date (in each case subject to
any applicable apportionment), and any mortgages and other liens created by
<PAGE>

Seller, which Seller is obligated to pay and discharge pursuant to the terms of
this Agreement, together with the cost of recording or filing of any instruments
necessary to discharge such liens and such judgments, shall be paid at the
Closing by Seller. Seller shall deliver to Purchaser, on the Closing Date,
instruments in recordable form sufficient to discharge any such mortgages or
other liens which Seller is obligated to pay and discharge pursuant to the terms
of this Agreement.

                  4.5 If the Title Commitments disclose judgments, bankruptcies
or other returns against other persons having names the same as or similar to
that of Seller, Seller, on request, shall deliver to the Title Company
affidavits showing that such judgments, bankruptcies or other returns are not
against Seller, or any affiliates. Upon request by Purchaser, Seller shall
deliver any affidavits and documentary evidence as are reasonably required by
the Title Company to eliminate the standard or general exceptions on the ALTA
form Owner's Policy.

                  4.6 Deleted prior to execution.

                  4.7 If Seller is unable to convey title in accordance with the
terms of this Agreement and Purchaser elects to terminate this Agreement, then
this Agreement shall terminate and except as provided in the following sentence,
neither party to this Agreement shall have any further rights or obligations
hereunder other than those which are expressly stated herein to survive any such
termination. Upon a termination of this Agreement by Purchaser, Seller shall
refund to Purchaser all charges made for (i) examining the title to all of the
Real Property, (ii) any appropriate additional municipal searches made in
accordance with this Agreement, and (iii) survey and survey inspection charges,
which refund obligation shall survive said termination.

                  4.8 Purchaser acknowledges that the property described as
Easement Area "2" on that certain map (filed November 29, 1983, SLR 11136)
described in the second recital of the Conservation Easement dated November 9,
1983 among Nabisco, Inc., the City of Stamford and the Environmental Protection
Board of the City of Stamford and recorded at Volume 2320, page 174 is being
conveyed to Purchaser, to be held by Purchaser as a nominee on behalf of Seller,
which nominee relationship is more particularly set forth in an agreement (the
"Nominee Agreement") to be executed by Seller and Purchaser at Closing, in a
form substantially in accordance with Section 26 of the Contribution and
Exchange Agreement between Robert Martin Company, LLC, Robert Martin-Eastview
North Company, L.P. and Cali Realty, L.P. and
<PAGE>

Cali Realty Corporation dated January 24, 1997.

apportionment of real estate taxes shall be upon the basis of the tax rate for
the preceding year applied to the latest assessed valuation. If subsequent to
the Closing Date, real estate taxes (by reason of change in either assessment or
rate or for any other reason) for the Real Property should be determined to be
higher or lower than those that are apportioned, a new computation shall be
made, and Seller agrees to pay Purchaser any increase shown by such
recomputation and vice versa.

                  11.2 Except as otherwise provided in this Agreement, the
adjustments shall be made in accordance with the customs in respect to title
closings in the State of New York.

                  11.3 Any errors in calculations or adjustments shall be
corrected or adjusted as soon as practicable after the Closing.

                  11.4 The provisions of this Section 11 shall survive the
Closing Date.

                  12.1 The obligations of Seller to deliver title to the
Property and to perform the other covenants and obligations to be performed by
Seller on the Closing Date shall be subject to the following conditions (all or
any of which may be waived, in whole or in part, by Seller):
<PAGE>

                           (a) The representations and warranties made by
Purchaser herein shall be true and correct in all material respects with the
same force and effect as though such representations and warranties had been
made on and as of the Closing Date.

                           (b) Purchaser shall have delivered to Seller all of
the documents provided herein for said delivery.

                  12.2 The obligations of Purchaser to accept title to the

Purchaser on the Closing Date shall be subject to the following conditions (all
or any of which may be waived, in whole or in part, by Purchaser):

                           (a) The representations and warranties made by Seller
herein shall be true and correct in all material respects with the same force
and effect as though such representations and warranties had been made on and as
of the Closing Date.

                           (b) Seller shall have performed all covenants and
obligations undertaken by Seller herein in all respects and complied with all
conditions required by this Agreement to be performed or complied with by it on
or before the Closing Date.

                           (c) The Title Company is unconditionally prepared to

                           (d) Seller shall have delivered to Purchaser all of
the documents provided herein for said delivery.

                           (e) The Real Property shall be in compliance with the
Transfer Act. Seller shall, at Seller's sole cost and expense, make all
submissions to, provide all information to and comply with all requirements of
the Connecticut Department of Environmental Protection or its successor. In the
event that the Real Property is not an establishment subject to the Transfer
Act, prior to the Closing, Seller shall, at its sole cost and expense, provide
to Purchaser an affidavit of an officer, member or manager of Seller stating
that the Real Property is not an establishment which is subject to the
provisions of the Transfer Act.

                           (f) There shall not be any sewer moratorium affecting
the Property.

         13. ASSIGNMENT.

                  13.1 This Agreement may not be assigned by Purchaser except to
a directly or indirectly wholly-owned subsidiary or subsidiaries of Purchaser,
or to a partnership in which any such wholly-owned subsidiary or subsidiaries
owns, either directly or indirectly, at least seventy-five (75%) percent of the
profits, losses and cash flow thereof and controls the management of the affairs
of such partnership (any such entity, a "Permitted Assignee") and any other
assignment or attempted assignment by Purchaser shall constitute a default by
Purchaser hereunder and shall be deemed null and void and of no force and
effect. In addition, at Closing, Purchaser shall have the right to cause Seller
to direct the Deed and other closing instruments to such party as Purchaser
shall direct. No assignment or direction of the closing instruments shall
relieve Purchaser from Purchaser's obligations under this Agreement.

         14. BROKER.

                  14.1 Purchaser and Seller represent that they have not dealt
with any brokers, finders or salesmen, in connection with this transaction, and
agree to indemnify, defend and hold each other harmless from and against any and
all loss, cost, damage, liability or expense, including reasonable attorneys'
fees, which either party may sustain, incur or be exposed to by reason of any
claim for fees or commissions made through the other party. The provisions of
this Section shall survive the Closing or other termination of this Agreement.

         15. Deleted prior to execution.

         16. CONDEMNATION.

                  16.1 In the event that prior to Closing, Seller shall become
aware of the institution or threatened institution of any proceedings, judicial,
administrative or otherwise, by eminent domain or otherwise, which propose to
affect a material portion of the Property, Seller shall give notice (a
"Condemnation Notice") to Purchaser promptly thereafter. Within fifteen (15)
days following receipt of the Condemnation Notice, Purchaser shall have the
right and option to terminate this Agreement by giving Seller written notice
thereof. Any damage to or destruction of a Property as a result of a taking by
eminent domain shall be deemed "material" for purposes of this Section if the
estimate of the damage, which estimate shall be performed by an insurance
adjuster and Purchaser's architect, shall exceed three (3%) percent of the
Purchase Price. Should Purchaser so terminate this Agreement in accordance with
this Section, neither party shall have any further liability or obligations to
the other. In the event Purchaser shall not elect to cancel this Agreement,
Seller shall assign all proceeds of such taking to Purchaser, same shall be
Purchaser's sole property, and Purchaser shall have the sole right to settle any
claim in connection with the Property.

         17. PUBLICATION; CONFIDENTIALITY.

                  17.1 Purchaser shall have the right to make such public
announcements or filings with respect to the acquisition as Purchaser may deem
reasonably prudent. Purchaser shall not issue any such announcement without the
prior approval of Seller as to the text of the announcement, not to be
unreasonably withheld or delayed; provided, however, that Purchaser
<PAGE>

shall be entitled to make such filings or announcements upon advice of counsel
as may be necessary or required.

                  17.2 Without the prior written consent of the other party,
until Purchaser shall make a public announcement as provided in Section 17.1,
neither Purchaser nor Seller shall disclose, and Seller and Purchaser will
direct their respective representatives, employees, agents and consultants not
to disclose, to any person or entity the fact that Purchaser and Seller have
entered into an agreement to acquire the Property or any of the terms,
conditions or other facts with respect to this Agreement. Notwithstanding the
foregoing, either party may disclose those terms and conditions which are
required to be disclosed pursuant to law or in order to comply with this
Agreement; provided, however, that the disclosing party shall use its best
efforts to limit the disclosure to the information necessary, shall advise any
party to whom disclosure is made that said terms and conditions are subject to a
confidentiality requirement and shall obtain the agreement of said party to keep
any information disclosed to it as confidential. In the event of a breach of the
provisions of this Section 17.2, either party shall be entitled to all of its
rights and remedies at law or in equity.

         18. REMEDIES

                  18.1 In the event Purchaser fails to perform on the Closing
Date, Purchaser's sole liability and Seller's sole recourse shall be limited to
the amount of the Deposit. Seller agrees that retention of the Deposit
constitutes fixed and liquidated damages resulting from Purchaser's default, and
Seller waives any other claim, at law or in equity, either against Purchaser or
against any person, known or unknown, disclosed or undisclosed.

                  18.2 (a) If, after complying with the terms of this Agreement,
Seller shall be unable to convey the Property in accordance with the terms of
this Agreement, the sole obligation and liability of Seller shall be to perform
in accordance with Section 4.7, following which this Agreement shall be deemed
canceled and the parties hereto shall be released of all obligations and
liabilities under this Agreement, except those that are expressly stated to
survive the cancellation or termination of this Agreement.

                           (b) In the event of any default on the part of Seller
or Seller's failure to comply with any representation, warranty or agreement in
any material respect, Purchaser shall be entitled to terminate this Agreement
upon notice to Seller, in which event neither party shall thereafter have any
further obligations under this Agreement; to commence an action against Seller
seeking specific performance of Seller's obligations under this Agreement; to
pursue all of its remedies at law or in equity; or to do any or all of the
above.

                  18.3 The acceptance of the Deed by Purchaser shall be deemed a
full performance and discharge of every agreement and obligation of Seller to be
performed under this Agreement, except those, if any, which are specifically
stated in this Agreement to survive
<PAGE>

the Closing or those which, by their terms, cannot be performed or complied with
until after the Closing.
                  18.4 The provisions of this Section 18 shall survive the
Closing or earlier termination of this Agreement.

                  (a) This Agreement and all of Purchaser's obligations
hereunder are strictly contingent upon Sellers obtaining the written consent of
all mortgage holders ("Mortgagee(s)") of the Existing Mortgages and Purchaser
taking title to the Properties subject to the Existing Mortgages and without
recourse (except the Property encumbered by the mortgage held by First Union
National Bank ("First Union"), which, absent an agreement between Purchaser and

<PAGE>

to recourse). A schedule setting forth each Existing Mortgage, the
identification of each Property encumbered thereby ("Mortgaged Premises"), the
name and address of each Mortgagee, the face amount, outstanding principal
balance, term, maturity date, interest rate and amount and frequency of periodic
payment and the date to which payment has been made of each Existing Mortgage is
attached hereto and made a part hereof as Schedule "F".
                  (b) In the event the aforesaid conditions shall not be
satisfied on or before Closing, Purchaser shall have the right to declare this
Agreement terminated and of no further force and effect, whereupon Escrow Agent
shall deliver to Purchaser the Letter of Credit. Notwithstanding the foregoing:
(i) if one or more Mortgagees do not consent to Purchaser taking title to a
Property or Properties subject to such Mortgagees' Existing Mortgages, and if
the portion of the Purchase Price allocated to the Properties encumbered by such
Existing Mortgages as set forth on Schedule "E" is less than ten (10%) percent
of the Purchase Price, then this Agreement shall be null and void with respect
to such Property or Properties, the Purchase Price shall be reduced accordingly
and the parties shall proceed to Closing hereunder with respect to all remaining
Properties; and (ii) if one or more Mortgagees do not consent to Purchaser
taking title to a Property or Properties subject to such Mortgagees' Existing
Mortgages, and if the portion of the Purchase Price allocated to the Properties
encumbered by such Existing Mortgages as set forth on Schedule
<PAGE>

"E" is ten (10%) percent or more of the Purchase Price, then Purchaser, in
addition to its rights set forth in clause (i) above, also shall have the right,
by notice to Seller, to terminate this Agreement. Notwithstanding the foregoing,
Seller shall have the right, by notice to Purchaser delivered within five (5)
days after the date Purchaser has elected to terminate this Agreement, to negate
Purchaser's termination by agreeing to pay all Existing Mortgages (including,
all premiums, penalties and fees) at the Closing.
                  (c) Sellers shall utilize their best efforts to obtain the
written consent of each Mortgagee to the following:
                           (i)  The transfer of title of the Mortgaged
Premises to Purchaser, subject to the Existing Mortgage, without recourse
(except for the Existing Mortgage held by First Union), and the amount of all
fees and costs (including reasonable legal fees) to be paid to each Mortgagee
(including, brokers) in connection therewith ("Transfer Fees"); and
                           (ii)  The pre-payment at or following Closing of
the balance of the Existing Mortgage, including the amount of all pre-payment
fees and penalties, if any, in connection therewith ("Pre-Payment Fees").
                  (d) Purchaser shall pay the first One Hundred Fifty Thousand
($150,000.00) Dollars on account of all Transfer Fees and Pre-Payment Fees;
Sellers shall pay all Transfer Fees and Pre-Payment Fees in excess of One
Hundred Fifty Thousand ($150,000.00) Dollars up to and including Two Hundred
Thousand
<PAGE>

($200,000.00) Dollars; and Purchaser shall pay all Transfer Fees and Pre-Payment
Fees in excess of Two Hundred Thousand ($200,000.00) Dollars.
                  (e) Purchaser shall have the sole and absolute right to
determine which Existing Mortgages shall be pre-paid at or following Closing and
shall pay all Pre-Payment Fees in connection therewith.
                  (f) To the extent that Purchaser elects to pre-pay any
Existing Mortgage at Closing, the Purchase Price shall not change and Purchaser
shall be required to increase the cash portion of the Purchase Price by an
amount equal to the then outstanding principal balance of such Existing Mortgage
(excluding, any prepayment premiums, penalties and fees), which additional cash
portion shall be paid to the applicable Mortgagee and shall not increase the
portion of the Purchase Price to be paid to Sellers.
                  (g) At Closing, each applicable Seller shall deliver to
Purchaser an estoppel certificate from its Mortgagee, dated not more than thirty
(30) days prior to Closing, in substantially the form attached hereto and made a
part hereof as Schedule "G" ("Mortgagee Certificate(s)"), which shall include as
to each Existing Mortgage, the following:
                           (i)  the face amount of the mortgage;
                           (ii)  the amount of the outstanding principal
balance;
                           (iii)  the maturity date;
                           (iv)  the interest rate;
<PAGE>

                           (v)  the amount and frequency of periodic
payments;
                           (vi) the date to which payments have been made; (vii)
                           the existence of any event of default by
either mortgagor or Mortgagee and/or of any circumstance which with the passage
of time and/or which with the giving of notice would constitute an event of
default by either mortgagor or Mortgagee, if not cured;
                           (viii)  the amount of any escrows held by
Mortgagee;
                           (ix)  copies of any notices of default sent by
Mortgagee to the applicable Seller or received from the
applicable Seller; and
                           (x)  copies of any notices sent by Mortgagee to
any tenant of the Mortgaged Premises or received from any such
tenant.
         5. TITLE.
                  (a) Each Seller shall convey title to each Property which it
owns and Purchaser shall accept Marketable Title (as hereinafter defined),
subject only to the encumbrances set forth on Schedule "H" ("Permitted
Encumbrances"). Marketable Title shall mean that fee title to each of the
Properties is vested in the applicable Seller and shall be insured as such by a
title company selected by Purchaser (herein referred to as the "Title Company")
at standard rates, that all of the Improvements shall remain in their present
location; and that Purchaser shall not
<PAGE>

incur any damage, cost or expense resulting from any encroachment or overlap
affecting any of the Properties. Title Company shall certify that the applicable
Seller has the right, authority and power to enter into and to perform its
obligations hereunder. The legal description in the Binders (as hereinafter
defined) and in the Deeds (as hereinafter defined) shall be in accordance with
current surveys or existing surveys with accompanying survey affidavits from the
applicable Seller, satisfactory to Title Company and Purchaser.
                  (b) Purchaser, at its cost and expense, shall order title
insurance binders and current surveys for each Property (herein referred to as
the "Binders" and "Surveys" respectively) and prior to the expiration of the Due
Diligence Period shall deliver to Sellers' attorney notice of any objections to
title and/or the Surveys which are not Permitted Encumbrances. After the
execution hereof, no further liens, encumbrances, easements or restrictions
shall be created or filed ("Subsequent Encumbrances") on or with respect to any
of the Properties. Each Survey shall include the information set forth on
Schedule "I" attached hereto and made a part hereof and each Binder, at the
request of Purchaser, shall contain the following endorsements so that at
Closing, Title Company will issue Owner's Policies of Title Insurance (American
Land Title Association Owner's Policy - 1992, or equivalent, in Purchaser's sole
judgment), in the full amount of the allocated Purchase Price for each Property
(the "Title Policy" or "Title Policies"):
<PAGE>

                           (i)  a zoning endorsement certifying that the
insured Property is not subject to any ordinance, regulation or restriction
which in any way would prohibit or restrict the construction, maintenance and/or
use of the insured Property for its present use;
                           (ii) an endorsement insuring contiguity between or
among all of the tracts or parcels of land comprising the insured
Property;
                           (iii)  an endorsement deleting any coverage
exclusions with respect to creditor's rights; and
                           (iv) an endorsement affirmatively insuring access
to public streets, highway and roadways.
         If any Binder discloses any exceptions, liens, encumbrances, defects or
objections other than the Permitted Encumbrances or if, after execution hereof,
a Subsequent Encumbrance shall be placed against any of the insured Property
(herein collectively called the "Title Defect(s)"), then Purchaser shall have
the right to: (i) require Sellers to use best efforts to cure any such Title
Defects provided that the cost to cure such Title Defects together with the
Costs of Compliance (as hereinafter defined) do not exceed the Environmental
Threshold (as hereinafter defined) (except that Sellers shall be obligated to
cure any Title Defects which can be removed solely by the payment of a sum of
money); (ii) attempt to cure any such Title Defect; (iii) accept such title as
Sellers shall be able to convey and proceed to Closing without reduction in the
Purchase Price; (iv)
<PAGE>

cause a title report and title insurance policy to be issued by another title
company without such Title Defect; (v) elect not to purchase such insured
Property and to proceed to purchase the remaining Properties, in which event,
the Purchase Price shall be reduced by an amount based on the allocation of the
Purchase Price set forth on Schedule "E", provided, however, if Seller gives
notice to Purchaser within five (5) days after Purchaser's election under this
subparagraph (v) that Seller intends to cure such Title Defects and thereafter
cures such Title Defects in accordance with the terms of this Agreement within
thirty (30) days after receipt of notice from Purchaser of its election under
this subparagraph (v), then such Property shall be included in the sale pursuant
to the terms of this Agreement; and/or (vi) if the portion of the Purchase Price
allocated to the Properties affected by Title Defects is ten (10%) percent or
more of the Purchase Price, declare this Agreement null and void, whereupon
Purchaser shall be entitled to the return of the Letter of Credit; provided,
however, if Seller gives notice to Purchaser within five (5) days after
Purchaser's election under this subparagraph (vi) that Seller intends to cure
such Title Defects and thereafter cures such Title Defects in accordance with
the terms of this Agreement within thirty (30) days after receipt of notice from
Purchaser of its election under this subparagraph (vi), then Purchaser's notice
of termination shall be deemed rescinded. The right of Purchaser to terminate
this Agreement may be exercised following the exercise of its other rights
<PAGE>

hereunder. The time of Closing shall be extended for a period of up to sixty
(60) days, if necessary, to permit Purchaser to pursue the exercise of its
rights hereunder.
                  (c) If at Closing there are liens or encumbrances against any
of the Properties other than Permitted Encumbrances, Sellers may use any portion
of the cash Purchase Price to satisfy same, provided Sellers, at Closing, either
shall: (1) deliver to Purchaser instruments in recordable form sufficient to
satisfy such liens or encumbrances of record, together with the cost of
recording or filing said instruments; or (2) deposit with Title Company
sufficient monies acceptable to Title Company to insure obtaining and recording
of such satisfactions and the issuance of a Title Policy for such Property to
Purchaser free and clear of any such liens or encumbrances, but only to the
extent that such liens or encumbrances are in favor of and held by institutional
lenders. The existence of any such liens or encumbrances shall not be deemed
objections or exceptions to title if Sellers shall comply with the foregoing
requirements.
                  (d) If a search of title discloses judgments, bankruptcies or
other returns against other persons or entities having names the same as or
similar to that of any Seller or any predecessor in title, such Seller, on
request, shall deliver to Title Company, an affidavit showing that such
judgments, bankruptcies or other returns are not against such Seller or such
predecessors in interest of such Seller.

indemnity agreement contained in this Paragraph 7.(a), the claim may, upon
written agreement of Sellers that they are obligated to indemnify against the
particular claim under the indemnity agreement contained herein, be settled by

liability hereunder unless such failure impairs the right to defend such action.
In the event any claim is brought against Sellers with respect to which
Purchaser may have liability under the indemnity agreement contained in this
Paragraph 7.(b), the claim may, upon written agreement of Purchaser that it is
obligated to indemnify against the particular claim under the indemnity
contained herein, be settled by Purchaser with the prior written consent of
Sellers, which shall not be unreasonably withheld.
                  (c) Sellers agree not to apply or return any security deposit

         9. CLOSING ADJUSTMENTS.
                  (a)  The following are to be apportioned as of the
Closing Date:
                           (i)  real property taxes;
                           (ii) water rates and charges;
                           (iii)  sewer taxes and rents;
                           (iv) all base rent payments;
                           (v)  common area and other additional rent
charges, if any;
                           (vi) fuel oil on hand, determined at Sellers'
cost;
                           (vii)  insurance premiums on transferable
policies, if any, approved by Purchaser;
                           (viii)  annual license, permit and inspection
fees, if any, provided that the applicable Seller's rights
thereunder (or with respect thereto) are transferable to
Purchaser; and
                           (ix)  charges and/or association fees or other
costs under any declaration, easement agreement or other instrument encumbering
or binding upon the Property.
<PAGE>

                  (b) (i) Apportionment of real property taxes, water rates and
charges and sewer taxes and rents shall be made on the basis of the fiscal year
for which assessed solely to the extent actually received by Sellers from
Tenants or actually paid or payable by Sellers. If the Closing Date shall occur
before any or all of the foregoing are fixed, the apportionment of real property
taxes shall be made on the basis of the tax rate for the preceding year applied
to the latest assessed valuation. After the final real property taxes, water
rates and charges and sewer taxes and rents are fixed, Sellers and Purchaser
shall make a recalculation of the apportionment of same, and Sellers or
Purchaser, as the case may be, shall make an appropriate payment to the other
based on such recalculation.
                           (ii) If at the time for the delivery of the Deeds,
any of the Premises or any part of any of them shall be or shall have been
affected by an assessment or assessments (including special and/or added) which
are or may become payable in annual installments of which the first installment
is then due or has been paid, then for the purposes of this Agreement all the
unpaid installments of any such assessment, including those which are to become
due and payable after the delivery of the applicable Deed for the affected
Premises, shall be deemed to be due and payable and to be liens upon such
Premises affected thereby and shall be paid and discharged by Seller upon the
delivery of the Deed for the Premises. If any assessment with respect to any
Premises is unconfirmed at the time of Closing, or if subsequent to Closing
<PAGE>

any assessment, including special or added, is determined to be incorrect, then,
immediately after the amount of the assessment has been established, or the
confirmed assessment corrected as a result of a prior error, Seller shall make
an appropriate payment to Purchaser within ten (10) days of the tax assessor's
calculation of the assessment. Notwithstanding the foregoing , if Tenants of any
Premises are obligated under a written lease for the payment of the entire
assessment (confirmed and/or unconfirmed), then with respect to such assessment,
Purchaser shall seek payment from the Tenants, and any assessment not otherwise
the obligation of the Tenants shall be the obligation of Seller. Seller shall
indemnify and hold Purchaser harmless from and against all costs and expenses,
including reasonable attorneys fees, incurred by Purchaser in connection with
Seller's failure to perform Seller's obligation under this Paragraph 9(b)(ii).
                  (c) If there shall be any water meters on any of the
Properties (other than meters measuring water consumption costs which are the
obligation of Tenants to pay), Sellers shall furnish readings to a date not more
than ten (10) days prior to the Closing Date, and the unfixed water rates and
charges and sewer taxes and rents, if any, based thereon for the intervening
time, shall be apportioned on the basis of such last readings.
                  (d) The amount of unpaid taxes, assessments, water charges and
sewer rents which Sellers are obligated to pay and discharge, with interest and
penalties thereon to the fifth (5th)
<PAGE>

day after the Closing Date, at the option of Sellers, may be allowed to
Purchaser out of the cash portion of the Purchase Price, provided that official
bills therefor with interest and penalties thereon are furnished by Sellers at
the Closing.
                  (e) If any refund of real property taxes, water rates and
charges or sewer taxes and rents is made after the Closing Date for a period
prior to the Closing Date, the same shall be applied first to the costs incurred
in obtaining same and second to the refunds due to Tenants by reason of the
provisions of their respective Leases. The balance, if any, of such refund shall
be paid to Sellers (for the period prior to the Closing Date) and Purchaser (for
the period commencing with the Closing Date).
                  (f) To the extent that any Seller receives rent payments after
the Closing Date for any period from and after the Closing Date, the same shall
be held in trust and immediately paid to Purchaser.
                  (g) All rent payments received by Sellers or Purchaser after
Closing shall be applied firstly against rents due and owing by such Tenant for
the periods from and after Closing and thereafter against rents due and owing
prior to Closing in inverse order of due date; provided, however, with respect
to the Tenant's listed on Schedule "J-1" ("Late Tenants"), if at Closing there
are past-due rents owed by Late Tenants for a period not to exceed the two (2)
months prior to the Closing Date (the "Arrearages"), then the rent payments
received by Sellers or
<PAGE>

Purchaser with respect to such Late Tenants on account of Arrearages after
Closing shall be applied first against out-of-pocket costs of collection, then
to such Arrearages and thereafter against rents due and owing after the Closing
Date.
                  (h) Nothing contained in Section (g) above shall prohibit any
Seller prior to Closing, at its own expense, from obtaining a promissory note
from any Tenant for any rental delinquencies due such Seller for a period prior
to Closing and instituting an action in its own name to collect such promissory
note; provided, however, that in no event shall any Seller be entitled to bring
suit under any Lease or seek to evict any Tenant or to recover possession of its
space.
                  (i) All realty transfer fees and charges (other than recording
fees for the Deeds) shall be borne by Seller.
         10. RISK OF LOSS.
                  (a) Sellers assume the risk of loss or damage to all of the
Properties beyond ordinary wear and tear until delivery of the Deeds to
Purchaser and shall notify Purchaser forthwith upon the occurrence of any such
casualty ("Casualty Notice"). In the event of any casualty in which the Casualty
Threshold (as hereinafter defined) is not established, or in the event of a
casualty in which the Casualty Threshold is established and if Purchaser elects
to complete the purchase of the Properties hereunder, the parties shall proceed
to Closing without any repairs required of Sellers, subject however to their
obligations pursuant to Existing Mortgages and/or Leases, and without any
<PAGE>

change in the Purchase Price, except as otherwise provided in subparagraph (b)
below, in which event the applicable Seller, subject to the rights of mortgage
holders, and the cost of necessary repairs incurred by such Seller, shall assign
its full right, title and interest in and to the entire insurance proceeds with
respect thereto (including the right to receive proceeds) arising from such
occurrence to Purchaser at Closing and Purchaser shall receive a credit against
the cash portion of the Purchase Price of an amount equal to any self-insurance
obligations of Sellers, including the deductible amount of the insurance policy
maintained by the applicable Seller covering such occurrence. Sellers shall
cooperate in all respects with Purchaser in connection with the collection of
such insurance proceeds, to the extent not collected by the time of Closing,
including the endorsing of any checks or the payment of any proceeds received by
Sellers on account of said insurance policies, and to the extent any insurance
proceeds shall have been received by Sellers prior to Closing, shall remit to
Purchaser the full amount thereof so collected, less any amounts applied to
repair or restoration of the applicable Property or Properties in accordance
with the Existing Mortgages and/or Leases.
                  (b) If, prior to the Closing Date, any Property or Properties
shall be damaged by fire or other casualty and the estimated cost of repair
and/or restoration shall exceed twenty-five (25%) percent of the portion of the
Purchase Price allocated
<PAGE>

to such damaged Property herein or ten (10%) percent of the total Purchase
Price, or reasonably shall be estimated to require more than one hundred eighty
(180) days to repair or restore (collectively, "Casualty Threshold"), Purchaser
may, by notice to Sellers, elect either (i) not to purchase such Property, in
which event the Purchase Price shall be reduced accordingly based on the
valuation set forth on Schedule "E", or (ii) to terminate this Agreement. If
this Agreement is so terminated the Letter of Credit forthwith shall be returned
to Purchaser. Purchaser shall notify Sellers of its decision within sixty (60)
days of receipt of the Casualty Notice, which shall include the amount of
insurance coverage, the amount of insurance received, if any, the reasonably
estimated cost of repair, the amount incurred by the applicable Seller for such
repairs and the reasonably estimated time in which to complete said repairs, and
the Closing shall be postponed accordingly.
                  (c) Notwithstanding the foregoing, any proceeds of loss of
rent insurance for a casualty occurring prior to the Closing Date, whether
received prior to or following the Closing, shall be apportioned as of the
Closing Date.
         11. CONDEMNATION. In the event that, prior to Closing, all or any
portion of any or all of the Properties shall be condemned or taken as the
result of the exercise of the power of eminent domain, or by deed in lieu
thereof (collectively, a "Taking"), or if such proceedings shall have commenced
or shall be threatened, Sellers promptly shall notify Purchaser ("Taking
Notice").
<PAGE>

Purchaser, in its sole judgment, shall notify Sellers within sixty (60) days
following receipt of the Taking Notice, that: (1) the remaining portion of a
specific Property is not suitable or economically viable for its intended use of
the affected Property, in which event Purchaser may terminate this Agreement
with respect to such Property; or (2) the remaining portion of the affected
Property is suitable and economically viable for its intended use, in which
event Closing shall proceed and Purchaser and the applicable Seller shall have
the right to participate jointly in the condemnation proceedings and the
proceeds thereof shall belong to the applicable Seller, subject to the rights of
mortgage holders, but Purchaser shall be entitled to a credit against the
Purchase Price in an amount equal to said proceeds, unless such condemnation
proceedings shall be pending on the Closing Date, in which event there shall not
be any credit and at Closing, the applicable Seller shall assign all its right,
title and interest in and to said proceedings and award to Purchaser.
Notwithstanding anything to the contrary contained herein, if there is a Taking
of two or more Properties, Purchaser may, upon notice to Sellers, terminate this
Agreement without further liability hereunder on the part of either party,
except that the Letter of Credit forthwith shall be returned to Purchaser.
         12. APPROVALS FOR TRANSFER. In the event that any Governmental
Authority shall have an ordinance, law, rule, regulation or other requirement
requiring a new Certificate of Occupancy or other governmental authorization to
be issued in
<PAGE>

connection with the transfer of title to any of the Properties, or in the event
that on the Closing Date there is any such requirement, then and in any of such
events, Sellers shall use their best efforts, at their sole cost and expense, to
obtain and deliver to Purchaser, the Certificate of Occupancy or other
governmental authorization.
         13. DUE DILIGENCE PERIOD.
                  (a) Through the period ending on the date of this Agreement
(the "Due Diligence Period"), Purchaser may perform, or cause to be performed,
tests, investigations and studies of or related to any or all of the Properties,
including, but not limited to, soil tests and borings, ground water tests and
investigations, percolation tests, surveys, architectural, engineering,
subdivision, environmental, access, financial, market analysis, development and
economic feasibility studies and such other tests, investigations or studies as
Purchaser, in its sole discretion, determines is necessary or desirable in
connection with the Properties and may inspect the physical (including
environmental) and financial condition of any or all of the Properties,
including but not limited to the Leases, Contracts, engineering and
environmental reports, development approval agreements, permits and approvals.
Purchaser shall conduct or cause to be conducted any tests and studies in a
manner which does not unreasonably impede the day-to-day operations of any of
the Properties, and shall repair and restore any portion of the surface of any
of the Properties disturbed by
<PAGE>

Purchaser, its agents, representatives or contractors during the conduct of any
tests and studies to substantially the same condition as existed prior to such
disturbance. Such right of inspection and the exercise of such right shall not
constitute a waiver by Purchaser of the breach of any representation, warranty,
covenant or agreement of Sellers which might, or should, have been disclosed by
such inspection.
                  (b) During the Due Diligence Period, Purchaser, its agents,
representatives and contractors, shall have unlimited access to all of the
Properties and other information pertaining thereto in the possession or within
the control of any of the Sellers for the purpose of performing such
studies,tests, borings, investigations and inspections for the purposes
described in this Paragraph. Sellers shall cooperate with Purchaser in
facilitating its due diligence inquiry and shall obtain, and use their best
reasonable efforts to obtain, any consents that may be necessary in order for
Purchaser to perform same. In addition, Sellers will deliver to Purchaser
promptly after request, true and complete copies of all test borings,
Environmental Documents, surveys, title materials and engineering and
architectural data and the like relating to any of the Properties that are in
any Seller's possession or under its control. In the event any additional
materials or information comes within any Seller's possession or control after
the date of this Agreement, such Seller promptly shall submit true and complete
copies of the same to Purchaser. Sellers shall notify
<PAGE>

Purchaser of any dangerous conditions on any of the Properties, including,
without limitation, conditions which due to the nature of the borings, studies,
investigations, inspections or testing to be performed by or on behalf of
Purchaser may pose a dangerous condition to Purchaser or Purchaser's agents,
representatives or contractors.
                  (c) Purchaser shall obtain, or cause its contractors, agents
and representatives to obtain, liability insurance in an amount equal to One
Million ($1,000,000.00) Dollars on a per occurrence and aggregate basis on
account of personal injury to one or more persons and property damage with
respect to Purchaser's activities and entry onto the Properties. Upon request of
Sellers, the policy shall name Sellers as additional insureds. In addition,
Purchaser agrees to indemnify and hold Sellers harmless from any damage or
injury to persons or property arising out of or in connection with Purchaser or
its contractors, agents or representatives entering upon the Properties.
                  (d) Purchaser may terminate this Agreement for any reason or
for no reason by notice to Sellers given within the Due Diligence Period. In the
event Purchaser terminates this Agreement during the Due Diligence Period, this
Agreement shall be null and void, the Letter of Credit forthwith shall be
returned to Purchaser and copies of any reports or studies prepared by third
parties as part of Purchaser's investigations during the Due Diligence Period
(if expressly permitted by such
<PAGE>

third party), shall be delivered to Sellers (except, if this Agreement is
terminated as a result of Sellers breach hereof). In the event Purchaser does
not terminate this Agreement by the end of the Due Diligence Period, Purchaser
shall be deemed to have elected not to terminate this Agreement pursuant to this
Section.
         14. ENVIRONMENTAL PROVISIONS.
                  (a) Notwithstanding anything to the contrary contained in this
Agreement, the obligation of Purchaser to pay the Purchase Price and otherwise
proceed to Closing shall be subject to the condition as to each Property, that
Sellers shall promptly apply for and obtain from the Element (as hereinafter
defined in Paragraph 14.(g)(iii) hereof) pursuant to ISRA (as hereinafter
defined in Paragraph 14.(g)(i) hereof), and deliver to Purchaser, at least five
(5) days prior to Closing (the "ISRA Compliance Date"), together with all
submissions upon which any one or more of the following is based, either:
                           (i) a Letter of Non-Applicability;
                           (ii)   a de minimis quantity exemption;
                           (iii)  an unconditional approval of the applicable
Seller's Negative Declaration; or
                           (iv)   an unconditional No Further Action Letter;
(collectively the "ISRA Approval"). In no event shall an ISRA Approval involve
any engineering or institutional controls, including without limitation,
capping, deed notice, declaration of environmental restriction or other
institutional control
<PAGE>

notice pursuant to P.L. 1993 c. 139, a groundwater classification exception area
or a well restriction area. If the requirements of this Paragraph 14.(a) are not
satisfied on or before the ISRA Compliance Date, Purchaser thereafter shall have
the right, by notice to Sellers, to: (A) extend the ISRA Compliance Date for a
period not to exceed ninety (90) days; (B) elect not to purchase any such
Property or Properties for which ISRA Approval has not been obtained, as more
particularly set forth in subparagraph (b) below, and purchase the balance of
the Properties; or (C) to terminate this Agreement if the allocated portion of
the Purchase Price for the Properties for which ISRA Approval has not been
obtained exceeds ten (10%) percent of the Purchase Price in the aggregate, in
which latter event this Agreement shall be rendered null and void and of no
further force or effect, the Letter of Credit forthwith shall be returned to
Purchaser and neither party shall have further liability or obligation to the
other under or by virtue of this Agreement. Notwithstanding any contrary
provision set forth above, if Purchaser fails to elect to extend the ISRA
Compliance Date for a period of ninety (90) days pursuant to Paragraph
14(a)(iv)(A) above, Seller shall nevertheless have the right to do so, on notice
to Purchaser. If Seller elects to extend the ISRA Compliance Date for a period
of ninety (90) days, then Purchaser shall not have the rights set forth in
Paragraphs 14(a)(iv)(B) and (C) above until the expiration of the ninety (90)
day period.
                  (b)  If Sellers shall be unable to satisfy the
<PAGE>

requirements of Paragraph 14(a) by the ISRA Compliance Date (as that date may be
extended by Seller or Purchaser pursuant to the provisions of Paragraph 14(a)),
and Purchaser does not elect to terminate this Agreement pursuant to the
provisions of Paragraph 14(a), then Purchaser shall have the right to
immediately purchase those Properties for which ISRA Approval has been obtained,
for the allocated portion of the Purchase Price for such Properties set forth on
Schedule "E", and upon the terms and conditions set forth in this Agreement. In
addition, notwithstanding any contrary provisions contained in this Agreement,
Purchaser shall continue to have the right, for a period of one (1) year from
the Closing Date, to purchase the balance of the Properties, as and when Sellers
shall obtain ISRA Approval for each such Property, for the allocated portion of
the Purchase Price for such Properties set forth on Schedule "E", and upon the
terms and conditions set forth in this Agreement.
         If Sellers shall fail to obtain ISRA Approval for all of the Properties
within one (1) year from the Closing Date, then Purchaser shall have the right
to either: (A) terminate this Agreement with respect to the balance of the
Properties for which ISRA Approval has not yet been obtained, in which event
this Agreement shall be rendered null and void and of no further force or effect
with respect to such Properties and neither party shall have any further
liability or obligation to the other under or by virtue of this Agreement with
respect to such Properties; or (B) to extend the ISRA Compliance Date with
respect to such
<PAGE>

Properties for such period of time as Purchaser shall elect, in Purchaser's sole
and absolute discretion.
         Notwithstanding any contrary provisions contained in this Agreement, if
the Closing on any of the Properties takes place on any date which is after the
first anniversary of the Closing Date, then the Closing shall take place in
accordance with the terms and conditions of this Agreement, with the exception
that the Purchase Price for such Property or Properties shall be determined
pursuant to Schedule "BB" attached hereto and made a part hereof.
         If Sellers fail to obtain ISRA Approval for any Property within three
(3) years of the Closing Date, then either party shall have the right to
terminate this Agreement with respect to such Property or Properties, on notice
to the other, in which event this Agreement shall be rendered null and void and
of no further force or effect with respect to such Property or Properties and
neither party shall have any further liability or obligation to the other under
or by virtue of this Agreement with respect to such Property or Properties.
                           (i)  After the Closing, Sellers shall cause
Sellers which are the owners of the Properties for which ISRA Approval has not
yet been obtained (the "Applicable Sellers") at Sellers' own cost and expense,
to promptly obtain or cause to be obtained, ISRA Approval for those Properties
not purchased by Purchaser at the Closing (the "Remaining Properties"). In no
event shall any of the foregoing result in engineering or
<PAGE>

institutional controls, including without limitation a deed notice or
declaration of environmental restrictions, or a groundwater classification
exception area or a well restriction area;
                           (ii) In order to obtain ISRA Approval for the
Remaining Properties, Sellers shall cause the Applicable Sellers, at Sellers'
own cost and expense, and in accordance with all currently existing or hereafter
enacted or promulgated Environmental Laws, to promptly undertake all action
(including without limitation, undertaking all Remedial Action, (as that term is
defined in subparagraph (iv) below) at the Remaining Properties or any real
property which is adjacent or contiguous thereto, or both, as the case may be)
required pursuant to ISRA, all of which shall be performed to the reasonable
satisfaction of Purchaser;
                           (iii) Sellers shall cause the Applicable
Sellers to notify Purchaser in advance of all meetings scheduled between the
Applicable Sellers or its representatives and the NJDEP, and Purchaser and their
representatives shall have the right, without the obligation, to attend and
participate in all such meetings. In addition, Sellers shall cause the
Applicable Sellers to deliver to Purchaser a copy of all submissions to be made
to the NJDEP, prior to submission to the NJDEP, and Purchaser shall have the
right, without the obligation, to comment upon each such submission, which
comments Sellers shall cause the Applicable Sellers to adopt;
<PAGE>

                           (iv) The term "Remedial Action" as used in this
subparagraph (b) shall mean all actions taken to cleanup, remove, remediate,
contain, treat, monitor, assess, evaluate or in any other way address
Contaminants in the indoor or outdoor environment; to prevent or minimize a
Discharge or threatened Discharge of Contaminants so they do not migrate or
endanger or threaten to endanger public health or welfare or the indoor or
outdoor environment; to perform pre-remedial studies and investigations and
post-remedial operation and maintenance activities; or any other actions
authorized or required by Environmental Laws. In no event shall Remedial Action
involve any engineering or institutional controls, including, without
limitation, a deed notice or declaration of environmental restrictions, or the
creation of a groundwater classification exception area or well restriction
area; and
                           (v)  The provisions of this subparagraph (b) shall
survive the Closing.
                  (c) Subject to the provisions of subparagraph (b) above, if
Sellers shall determine prior to the Closing, with respect to the Properties or
after the Closing with respect to the Remaining Properties, that the reasonably
estimated costs of compliance (the "Costs of Compliance") with the provisions of
Paragraph 14(a) with respect to all of the Properties (as evidenced by a cost
estimate prepared by Sellers' environmental consultant, itemized with
specificity as to the Property or Properties involved, the tasks to be
performed, the costs of
<PAGE>

performing each task, and the basis for such determination) shall exceed the sum
of One Million One Hundred Sixty-Five Thousand ($1,165,000.00) Dollars
("Environmental Threshold"), then Sellers shall immediately notify Purchaser
("Environmental Notice") and simultaneously provide Purchaser with a copy of
such cost estimate. If Purchaser shall disagree with the cost estimate of
Sellers' environmental consultant, it shall so notify Sellers within ten (10)
days of its receipt of such Environmental Notice, in which event the Costs of
Compliance shall be determined by an independent environmental consultant or
engineer, practicing in New Jersey, with at least ten (10) years' experience in
performing environmental services for property similar to the Properties in New
Jersey, mutually selected by the parties within ten (10) days of Purchaser's
notice of disagreement with the cost estimate. The selected environmental
consultant shall make an independent written estimate of the Costs of
Compliance, with the same specificity as set forth above, and provide Sellers
and Purchaser with a copy of such cost estimate within twenty (20) days of
selection. This costs estimate shall be binding on the parties for purposes of
Paragraph 14(a). If the parties are unable to agree upon the selection of an
independent environmental consultant within the time frame set forth above, or
if such selected environmental consultant shall fail to provide the estimate of
the Costs of Compliance as required, then either party, on notice to the other,
may apply to a Court of competent jurisdiction of the State of New Jersey to
make the
<PAGE>

appointment and the other party shall be bound by the Court's jurisdiction and
determination without any right of appeal. The estimate of the Costs of
Compliance determined by any environmental consultant selected by the Court
shall be made within twenty (20) days of such consultant's appointment and
pursuant to the provisions set forth in this subparagraph 14(c). All costs and
fees charged by the independent consultant in determining the Costs of
Compliance hereunder, shall be shared equally between the parties. If the Costs
of Compliance as estimated by the independent environmental consultant shall
exceed the Environmental Threshold, then Purchaser, within twenty (20) days from
receipt of the Costs of Compliance, shall have the right, in Purchaser's sole
discretion, to elect to: (i) purchase all Properties or all Remaining
Properties, as the case may be, in accordance with the provisions hereof in
which event, Sellers shall proceed to comply with the provisions of Paragraph
14(a) and Purchaser shall reimburse Sellers for all reasonable costs in excess
of the Environmental Threshold within thirty (30) days of receipt of copies of
all paid bills therefor; (ii) terminate this Agreement with respect to all of
the Properties or of the Remaining Properties for which the Costs of Compliance
shall exceed the Environmental Threshold, as the case may be, in which event the
Purchase Price shall be reduced accordingly based on the allocations set forth
on Schedule "E" and the parties shall proceed to Closing hereunder with respect
to the balance of the Properties in accordance herewith, and with the provisions
of
<PAGE>

Paragraph 14(b) and with the obligations of Sellers to comply with the
provisions of Paragraphs 14(a) and (c) and the obligation of Purchaser to pay
all Costs of Compliance in excess of the Environmental Threshold, if any, for
such Properties as Purchaser shall, in its sole discretion, purchase hereunder;
or (iii) terminate this Agreement, in which event Escrow Agent shall deliver to
Purchaser the Letter(s) of Credit and neither party shall have any further
rights or obligations to the other hereunder. If Purchaser fails to deliver
notice of its election to Sellers within the aforesaid twenty (20) day period,
then Purchaser shall be deemed conclusively to have elected to terminate this
Agreement pursuant to subparagraph (ii) as to the Properties or the Remaining
Properties for which the Costs of Compliance shall exceed the Environmental
Threshold, as the case may be, without regard to the Costs of Compliance, in
which event the Purchase Price shall be reduced accordingly based on the
allocations set forth on Schedule "E" and the parties shall proceed to Closing
hereunder with respect to the balance of the Properties.
                  (d) Seller has previously delivered to Purchaser, and
subsequently promptly upon receipt by any Seller or its representatives, each

then Sellers shall cure such violation of Environmental Law or undertake such
Remedial Action, at Sellers sole cost and expense, but only upon the terms and
conditions set forth herein:

placed on any of the Properties;
                           (iv) Sellers shall notify Purchaser in advance of

reimburse Purchaser for the reasonable costs Purchaser incurs in connection with
its review of or comments to any such submission, within five (5) days of
Purchaser's demand;
                           (v)  All Remedial Action or other action required
pursuant to Environmental Laws shall be performed without interfering with the
ownership of, or operations at the Properties in question, and in compliance
with all Environmental Laws and any other applicable federal, state, county or
municipal statutes, laws, ordinances, rules or regulations and pursuant to a
right of access agreement reasonably acceptable to Purchaser, which shall
include, without limitation a broad indemnification of Purchaser with respect to
any work to be performed on any Property by Sellers; and
                           (vi) Notwithstanding any contrary provisions
contained herein, in no event shall Sellers rights pursuant to this Paragraph

                           (iii)  Any costs incurred by Purchaser in excess
of one hundred and fifty thousand ($150,000) Dollars in each of the first two
years following Closing shall not be included in the calculation of Costs of
Tenant Work for such particular year.
         In addition, if Purchaser and a Tenant agree to terminate
<PAGE>

the existing lease between them for reasons other than a default of Tenant
thereunder, then the costs of tenant improvement work incurred by Purchaser for
such space shall not be included in the Costs of Tenant Work.
                  (b) During the first two (2) years following Closing, Sellers
shall be responsible for the aggregate Costs of Tenant Work at any or all of the
Properties in excess of One Million Two Hundred Thousand ($1,200,000.00)
Dollars; provided, however, that the cumulative costs of tenant improvement work
exceeding the product of (i) the aggregate square footage for applicable tenants
for a particular year for the specific category as set forth on Schedule "Z" and
(ii) the applicable T.I. Allowances shall not be included in the calculation of
the Tenant Work Threshold for such particular year.
                  (c) If, at the end of the first year following Closing, the
Costs of Tenant Work shall exceed the Tenant Work Threshold, but be less than
Six Hundred Ninety Thousand ($690,000.00) Dollars, such excess shall be
accumulated and deducted from the Tenant Work Threshold for the second year
following Closing (i.e. resulting in a lower Tenant Work Threshold for the
second year). If the Costs of Tenant Work shall exceed Six Hundred Ninety
Thousand ($690,000.00) Dollars at the end of the first year following Closing,
then within thirty (30) days after delivery of the Notice of Cost (as
hereinafter defined), Sellers shall deliver to Purchaser the Tenant Work Letter
of Credit (as hereinafter defined) in an amount equal to
<PAGE>

all Costs of Tenant Work in excess of the Tenant Work Threshold, as security for
the payment of all obligations of Sellers under this Paragraph 23. The Tenant
Work Letter of Credit shall be a clean, irrevocable, non-documentary and
unconditional letter of credit (the "Tenant Work Letter of Credit") issued by
and drawable upon any commercial bank or national banking association with
offices for banking purposes in Northern New Jersey, which shall have
outstanding unsecured, uninsured and unguaranteed indebtedness, or shall have
issued a letter of credit or other credit facility that constitutes the primary
security for any outstanding indebtedness (which is otherwise uninsured and
unguaranteed), that is then rated, without regard to qualification of such
rating by symbols such as "+" or "-" or numerical notation, "Aa" or better by
Moody's Investors Service and "AA" or better by Standard & Poor's Corporation,
and has combined capital, surplus and undivided profits of not less than Five
Hundred Million ($500,000,000.00) Dollars. Said Tenant Work Letter of Credit
shall name Purchaser as beneficiary, have a term of not less than thirteen (13)
months, permit multiple drawings, be fully transferable by Purchaser without the
payment of any fees or charges by Purchaser or any transferee, and otherwise be
substantially in the form attached as Schedule "V". Purchaser shall have the
right to draw the full amount of the Tenant Work Letter of Credit, by sight
draft, if the Tenant Work Letter of Credit is not renewed or replaced within
thirty (30) days prior to its expiration date or if Sellers fail to pay
Purchaser all
<PAGE>

sums due under this Paragraph 23 within thirty (30) days after delivery of the
Notice of Cost, whichever shall be the earlier to occur. If Sellers shall pay
all sums due Purchaser hereunder or if no sums are due Purchaser hereunder, the
Tenant Work Letter of Credit shall be returned to Sellers. Notwithstanding the
foregoing, if the Costs of Tenant Work in the first year following Closing shall
exceed Nine Hundred Thousand ($900,000.00) Dollars, Sellers, in addition to
posting such Tenant Work Letter of Credit, shall pay Purchaser, or, at
Purchaser's election, to subcontractors, materialmen and/or brokers in
immediately available funds, within thirty (30) days after delivery of the
Notice of Cost, all amounts exceeding Nine Hundred Thousand ($900,000.00)
Dollars. If the aggregate Costs of Tenant Work at the end of the second year
following Closing shall exceed One Million Two Hundred Thousand ($1,200,000.00)
Dollars, then Sellers shall pay all sums in excess of the Tenant Work Threshold
(less any sums previously paid by Sellers hereunder) to Purchaser or, at
Purchaser's election, to subcontractors, materialmen and/or brokers within
thirty (30) days following delivery of Notice of Costs. Following each of the
first two (2) years after Closing, Purchaser shall notify Sellers, in writing in
reasonable detail, the Costs of Tenant Work incurred by Purchaser during such
year and the amount required to be paid by Sellers ("Notice of Costs"). If the
aggregate Costs of Tenant Work during the first two (2) years following Closing
shall not exceed One Million Two Hundred
<PAGE>

Thousand ($1,200,000.00) Dollars, then Purchaser shall not owe any sums to
Sellers pursuant to this Paragraph 23, and an amount equal to all monies
previously paid by Sellers on account of this Paragraph 23, together with the
Tenant Work Letter of Credit shall be paid or delivered to Sellers, as the case
may be, within thirty (30) days after the end of the second year following
Closing.
                  (d) During the two (2) year period following Closing, McGarvey
Development Company ("McGarvey"), an affiliate of Sellers, shall be permitted to
bid upon any tenant improvement work. If McGarvey is awarded the bid, it shall
utilize employees and subcontractors who shall not cause labor conflicts. If
McGarvey is not awarded the bid, Purchaser shall select the lowest responsible
bidder to perform tenant improvement work.
                  (e) If Sellers shall default in their obligations under this
Paragraph 23, in addition to all other remedies Purchaser may have under this
Agreement or at law or in equity, Purchaser shall have the right to off-set such
amounts against the purchase price of any Development Property and/or any
property to be sold pursuant to the T&N Agreement.
                  (f) In the event of a dispute as to the propriety of any Costs
of Tenant Work, Sellers shall have the right to deliver a dispute notice (the
"Dispute Notice") to Purchaser within ten (10) days following receipt of the
applicable Notice of Costs. The Dispute Notice, to be valid, shall be
accompanied by a detailed statement as to the basis for the dispute and shall be
<PAGE>

accompanied by the tender of performance or payment of that portion of the sum
due as to which Seller does not take issue, limiting the dispute to only the net
amount actually disputed. Such dispute may be litigated under the provisions of
any simplified procedure for court determination of dispute applicable under the
laws of the State of New Jersey, or, with the mutual agreement of the parties,
may be submitted to arbitration, in either of which events, all parties will
join in request for expedition in the disposition of any proceeding brought to
resolve the dispute. In such circumstances, Sellers obligation to make such
reimbursement as to any matter in which a bona fide dispute has been raised will
be postponed to a date which is ten (10) days following the final determination
of the arbitrators, court or other forum or, in the event that the dispute is
resolved before any such final determination, within ten (10) days of the
judgment, settlement, or other resolution of the dispute. The prevailing party
in the dispute shall be reimbursed for any court charges related to the
resolution of the dispute and the attorney's fees in a reasonable amount.
         24. POST CLOSING MANAGEMENT.
                  (a) For a period of three (3) months following Closing
("Interim Management Period"), an entity designated by Sellers and acceptable to
Purchaser shall be retained to perform the non-administrative aspects of the
management of all of the Properties ("Interim Manager"), such as the repair and
maintenance of all of the Properties and the day-to-day dealing with all the
Tenants of
<PAGE>

the Properties. Interim Manager shall not be responsible for the leasing,
accounting, bookkeeping or financial aspects of the management of any of the
Properties, such as the calculation, billing and collection of rent and common
area charges, and the payment of costs and expenses incurred in the operation of
the Properties.
                  (b) It is acknowledged that Sellers presently receive an
annual aggregate fee equal to two (2%) percent of the gross rentals (due or
collected, as the case may be) which fee is billed to Tenants as part of common
area maintenance charges. During the Interim Management Period, Purchaser shall
pay Interim Manager an amount equal to one (1%) percent of the monthly gross
rentals (due or collected, as the case may be) for each full month of the
Interim Management Period, which fee shall be prorated on a daily basis for any
partial month.
                  (c) Interim Manager shall bill Purchaser for its time and
material costs and expenses expended in the performance of its management
duties. Purchaser shall have the right to bill either specific Tenants for whom
such work was performed or all applicable Tenants as part of common area
maintenance charges if such work was not performed for specific Tenants, and in
either of such events, such payments of Tenants shall be made to and retained by
Purchaser.
                  (d) Purchaser reserves the right to require Interim Manager to
enter into an interim management agreement to reflect the provisions of this
Paragraph 24 in substantially the form
<PAGE>

annexed hereto as Schedule "W" and made a part hereof.
                  (e) Following the Interim Management Period, Purchaser shall
assume responsibility for all operations and management of all of the Properties
and shall have the right, but not the obligation, to hire the following
employees of Interim Manager or related entities:
         4 Management construction employees;
         1 property manager employee; and
         1 receptionist.
         25. POST CLOSING RESTRICTIONS.
                  (a) Except as otherwise set forth herein, for a period of
three (3) years commencing on the Closing Date, neither John S. McGarvey nor
William G. Price, Jr. ("Principals"), each of whom is a shareholder, officer,
director, partner, manager and/or employee of some or all of Sellers, existing
managing entities, Interim Manager or related entities, either directly or
indirectly, to or for the benefit of any person, firm, partnership, corporation
or other entity, shall: call upon, solicit, divert, accept any business or
patronage from, or attempt to call upon, solicit or divert any of the tenants of
the Property or any potential tenants of the Property of which either has
knowledge, for the leasing and/or purchasing of industrial, warehouse and/or
office real property, or engage or become interested, either as a principal,
partner, agent, employee, shareholder or director of any corporation,
association or other entity, or in any other manner or capacity whatsoever, in
the
<PAGE>

business of developing, managing, leasing or selling industrial, warehouse
and/or office real property at any location situated within the State of New
Jersey and within fifteen (15) miles from any portion of the Property.
                  (b) The provisions of Subparagraph (a) shall not apply to the
Development Property, as to which the applicable provisions of the Agreement of
Sale shall govern and control nor to the property located in the Township of
Westampton, County of Burlington and known as Block 202, Lots 1, 2, and 4 on the
tax map of Westampton Township (the "Westampton Property"), nor to the
Additional Property (as hereinafter defined).
                  (c) It is acknowledged that each of the covenants, obligations
and restrictions ("restrictions") set forth in this Paragraph 25 is separate and
distinct from each and every other restriction, so that in the event all or any
portion of any restriction is deemed invalid or unreasonable, each of the
remaining restrictions shall be deemed divisible and independent therefrom,
shall remain in full force and effect and each Principal consents to such
modifications of any such restrictions as a court may deem reasonable.
                  (d) It is acknowledged that each of the above restrictions is
fair, reasonable and constitutes a material inducement to Purchaser to purchase
the Property, shall be construed and enforced independently of any other
agreement herein and the existence of any claim by Sellers and/or Principals
against Purchaser shall not constitute a defense to
<PAGE>

the enforcement by Purchaser of the restrictions set forth above.
                  (e)  If this Agreement is terminated as a result of
Purchaser's default under this Agreement, the T&N Agreement, the 2 Commerce
Agreement or the Agreement of Sale, the restrictions set forth in this Paragraph
25 shall be deemed terminated and of no further force and effect. If this
Agreement is terminated by Purchaser with respect to a particular Property (not
as a result of Seller's default under this Agreement), then the restrictions set
forth in this Paragraph 25 with respect to such Property only shall be
terminated and of no further force and effect.
                  (f) In the event Principals shall, at any time during the term
of the restrictions set forth in this Paragraph 25, receive a bona fide offer or
solicitation (the "Solicitation"), to engage or to become interested, either as
a principal, partner, agent, employee, shareholder or director of any
corporation, association or other entity, or in any other manner or capacity
whatsoever, in a business which would be violative of the restrictions set forth
in this Paragraph 25, which Solicitation Principals wish to accept, Principal
shall deliver a notice (hereinafter referred to as the "Solicitation Notice") to
Cali Realty setting forth all of the terms of said Solicitation together with a
true copy of the Solicitation (which must be in writing). Cali Realty shall
thereafter have the right, exercisable by notice to Principals, within thirty
(30) days after the date of receipt of the Solicitation Notice, to elect to
pursue such Solicitation either individually, or, at Cali
<PAGE>

Realty's election, by joint venturing same with Principals. In the event Cali
Realty shall elect to pursue such Solicitation individually, Principals shall
assign to Cali Realty all of their right, title and interest in and to such
Solicitation and the right to negotiate the terms and conditions of the
transactions contemplated in the Solicitation Notice in which event the
restrictions set forth in this Paragraph 25 shall continue to be effective and
shall remain in full force and effect. If Purchaser does not elect to pursue
such Solicitation, then Principals may, with respect to the transactions set
forth in the Solicitation Notice, pursue such transactions, notwithstanding the
restrictions set forth in this Paragraph 25. Nothing contained herein shall be
deemed a waiver or a release of Principals from the restrictions set forth in
this Paragraph 25 with respect to any other activities not encompassed within
the particular Solicitation Notice.
         26. ESCROW AGENT.
                  (a) The Letter of Credit shall be held in escrow by Escrow
Agent and released on the terms hereinafter set forth.
                  (b) If Escrow Agent receives notice from Purchaser or
Purchaser's attorney that Purchaser has terminated this Agreement pursuant to

obligations pursuant to this Agreement, Escrow Agent shall deliver a copy of
such notice to Purchaser. If Escrow Agent shall not have received notice of
objection from Purchaser within ten (10) days after Escrow Agent has delivered
such notice, Escrow Agent shall deliver the Letter of Credit to Sellers. If
Escrow Agent shall receive a timely notice of objection from Purchaser as
aforesaid, Escrow Agent promptly shall forward a copy thereof to Sellers.
                  (f) If Escrow Agent receives a notice signed by Purchaser or
Purchaser's attorney stating that this Agreement has been canceled or terminated
and that Purchaser is entitled to the Letter of Credit, or that Sellers have
defaulted in the performance of their obligations pursuant to this Agreement,
Escrow Agent shall deliver a copy of such notice to Sellers. If Escrow Agent
shall not have received notice of objection from Sellers within ten (10) days

                  (g) If Escrow Agent receives notice from either party
authorizing delivery of the Letter of Credit to the other party,
<PAGE>

Escrow Agent shall deliver the Letter of Credit in accordance with such
instructions.
                  (h) If Escrow Agent receives a notice of objection as
aforesaid, Escrow Agent shall convert the Letter of Credit to cash and hold such
proceeds in an interest bearing FDIC insured bank in New Jersey until Escrow
Agent receives either: (i) a notice signed by both Sellers and Purchaser stating
who is entitled to the Letter of Credit; or (ii) a final order of a court of
competent jurisdiction directing disbursement in a specific manner, in either of
which events Escrow Agent shall deliver the Letter of Credit in accordance
herewith or in accordance with such notice or order. Escrow Agent shall not be
or become liable in any way or to any person for its refusal to comply with any
requests or demands until and unless it has received a direction of the nature
described in (i) or (ii) above.
                  (i) Notwithstanding the foregoing provisions of Subparagraph
(g) above, if Escrow Agent shall have received a notice of objection as
aforesaid, or shall have received at any time before actual delivery of the
Letter of Credit, a notice signed by either Sellers or Purchaser advising that
litigation between Sellers and Purchaser over entitlement to the Letter of
Credit has been commenced, Escrow Agent shall have the right, upon notice to
both Sellers and Purchaser to deposit the Letter of Credit with the Clerk of the
Court in which any litigation is pending, whereupon Escrow Agent shall be
released of and from all
<PAGE>

liability hereunder except for any previous gross negligence or
willful default.
                  (j) Escrow Agent shall not be liable for any error or judgment
or for any act done or omitted by it in good faith, or for any mistake of fact

willful misconduct or gross negligence.
                  (k) Escrow Agent's obligations hereunder shall be as a
depositary only, and Escrow Agent shall not be responsible or liable in any
manner whatever for the sufficiency, correctness, genuineness or validity of any
notice, instructions or other instrument furnished to it or deposited with it,
or for the form of execution of any thereof, or for the identity or authority of
any person depositing or furnishing same.
                  (l) Escrow Agent shall not have any duties or responsibilities
except those set forth in this Agreement and shall not incur any liability in
acting upon any signature, notice, request, waiver, consent, receipt or other
paper or document believed by it to be genuine, and Escrow Agent may assume that
any person purporting to give any notice or advice on behalf of any party in
accordance with the provisions hereof has been duly authorized to do so.
                  (m) Escrow Agent shall be entitled to consult with counsel in
connection with its duties hereunder, including attorneys at its firm. The
parties shall reimburse Escrow Agent, jointly and severally, for all costs and
expenses incurred by
<PAGE>

Escrow Agent in performing its duties as Escrow Agent including, but not limited
to, reasonable attorneys' fees (either paid to retained attorneys or amounts
representing the fair value of services rendered to itself).
                  (n) The terms and provisions of this Paragraph shall create no
right in any person, firm or corporation other than the parties hereto and their
respective successors or assigns, and no third party shall have the right to
enforce or benefit from the terms hereof.
                  (o) In the event of any dispute, disagreement or suit between

transaction contemplated by this Agreement, Escrow Agent shall file Form 1099
information return and send the statement to Sellers as required under the
aforementioned statute and regulation.
         27. RIGHT OF FIRST REFUSAL. In the event Sellers, or any affiliate of
Sellers which owns the Westampton Property and/or the property described on
Schedule "Y" (the "Additional Property") ("Owner") shall receive a bona fide
offer (the
<PAGE>

"Offer") to purchase the Westampton Property and/or the Additional Property, or
any portion thereof, which Offer such Owner wishes to accept, Owner shall
deliver a notice (hereinafter referred to as the "Offer Notice") to Purchaser
setting forth all of the terms of said Offer together with a true copy of the
Offer (which must be in writing). Purchaser shall thereafter have the right,
exercisable by notice to Owner, within thirty (30) days after the date of
receipt of the Offer Notice, to elect to purchase the Westampton Property and/or
the Additional Property, or any portion thereof, as the case may be, upon the
same terms and conditions set forth in the Offer and, if Purchaser so elects,
within ninety (90) days after the date of receipt of such Offer Notice,
Purchaser and Owner shall enter into a purchase agreement in substantially the
form of this Agreement (including the provisions of Paragraph 14 hereof)
reflecting the applicable terms of the Offer for the purchase of the Westampton
Property and/or the Additional Property, or any portion thereof, as the case may
be. At Closing, Purchaser shall pay the purchase price set forth in the Offer
Notice thereof (less any amount which would have been attributable to brokerage
commissions) by wire transfer of United States funds to the account designated
by Owner. Owner and Purchaser agree to execute a Memorandum of this Agreement
(the "Westampton Memorandum"), in recordable form, setting forth the rights set
forth in this Paragraph 27, which Purchaser may record against the Westampton
Property and the Additional Property.
<PAGE>

         28. ROLLBACK TAXES. Any "rollback taxes" assessed or to be assessed
against any Premises identified on Schedule "B" pursuant to the Farmland
Assessment Act of 1964, N.J.S.A. 54:4-23.1, et seq., shall be paid by Seller. If
rollback taxes will be due with respect to any Premises but are not assessed at
the Closing Date, a good-faith estimate of the amount of same shall be obtained
by the parties from the tax assessor of the applicable Township, at least
twenty-four (24) hours prior to Closing, and Seller shall pay one hundred
twenty-five (125%) percent of the amount of said estimate from the proceeds at
Closing into escrow to be held by the Title Company until such time as the
rollback tax assessment against the respective Premises is made. Upon Title
Company's receipt of notice from Purchaser that said rollback taxes have been
assessed against the Premises, Title Company shall, within three (3) business
days thereof, pay said taxes to the appropriate Township. In the event the
amount of the monies being held in escrow by Title Company are not sufficient to
cover payment of said rollback taxes, then Seller shall promptly pay to
Purchaser any additional monies that are due and payable by Seller in accordance
with the terms and provisions of this Paragraph; and in the event the amount of
the escrow monies are in excess of the amount of said rollback taxes, then Title
Company shall disburse the remaining balance of the escrow funds to Seller after
the amount of the escrow monies due to Purchaser have been disbursed to the
appropriate Township, in accordance with the terms and provisions of the
immediately
<PAGE>

proceeding sentence. Seller shall indemnify and hold Purchaser harmless from and
against all costs and expenses, including reasonable attorneys fees, incurred by
Purchaser in connection with Seller's failure to perform Seller's obligations
under this Paragraph 28.
         29. MISCELLANEOUS.

                  (e) This Agreement constitutes the entire agreement between
the parties hereto with respect to the subject matter hereof. No variations or
modifications of or amendments to the
<PAGE>

terms of this Agreement shall be binding unless in writing and signed by the

                  (f) The terms, conditions, covenants and provisions of this
Agreement shall be deemed to be severable. If any clause or provision herein

competent jurisdiction or by operation of any applicable law, the same shall be
deemed to be severable and shall not affect the validity of any other clause or
provision herein, but such other clauses or provisions shall remain in full
force and effect.
                  (g) The obligations of each party to complete the transactions
contemplated hereby is subject to the satisfaction, as of Closing, of all of the

beneficiary of such condition or obligation.
                  (h) Each party, at its sole cost and expense, shall have the
right to record a short form memorandum of this Agreement, which memorandum

accordance with the substantive laws of the State of New Jersey.
         30. SELLER'S RIGHT TO EXCHANGE PROPERTY.
                  (a) (i) Seller shall have the right, exercisable at least five
(5) days prior to Closing, to elect to exchange the Property for other property
of like kind ("Exchange Property") pursuant to Section 1031 of the Internal
Revenue Code of 1986, as amended.
                           (ii) If Seller elects to effect any exchange, it
shall notify Purchaser as to all details thereof, and Purchaser shall execute a
contract to purchase the Exchange Property in a form satisfactory to Seller
(hereinafter called the "Exchange Contract"), and immediately thereafter shall
assign all of its right, title and interest in and to the Exchange Contract to
the Exchange Escrow Agent, as hereinafter defined. The funds required to pay the
deposit under the Exchange Contract shall be provided to Purchaser by Seller or
Exchange Escrow Agent. The Exchange Contract shall provide for the right of
assignment by Purchaser to Exchange Escrow Agent and/or Seller without recourse,
and that the seller of the Exchange Property shall look only to the deposit
monies thereunder as liquidated damages, there being no liability on the part of
Purchaser to said seller.
<PAGE>

Purchaser shall not be obligated to execute an Exchange Contract which would
require Purchaser to be personally liable on any indebtedness or to incur any
cost or expense which would increase Purchaser's liability beyond that liability
incurred by Purchaser hereunder.
                           (iii)  In no event, however, shall the closing of
title to the Property be delayed due to the inability of Seller to select an
Exchange Property or close title thereto.
                  (b) (i) If Seller shall elect to exchange the Property
pursuant to this Paragraph, whether or not an Exchange Property has been
designated, as herein set forth, the Purchase Price, exclusive of the
satisfaction of liens, payment of closing costs and other permitted expenses,
shall be deposited with the Exchange Escrow Agent ("Escrow Account"), subject to
the Exchange Escrow Agent executing an agreement reasonably satisfactory to
Purchaser whereby Exchange Escrow Agent agrees to be bound by the terms and
conditions of this Paragraph 30, and shall not be paid to Seller at Closing. The
Escrow Account shall be held by Exchange Escrow Agent in an interest bearing
account, pursuant to the terms hereof. The interest earned upon the Escrow
Account while being held by Exchange Escrow Agent shall be added to the Escrow
Account and shall be paid to Seller at the closing of the Exchange Property.
                           (ii) Purchaser appoints its title insurance
company or such other title insurance company or other entity as
Purchaser reasonably may designate, its agent, in order to
<PAGE>

effectuate the Exchange (the "Exchange Escrow Agent"). Purchaser and Seller
shall cooperate with each other and Exchange Escrow Agent and promptly shall
sign and deliver to Exchange Escrow Agent all documents reasonably deemed
necessary by Seller in order to qualify this transaction pursuant to Internal
Revenue Code Section 1031.
                           (iii)  Seller shall pay all fees relating to the
Escrow Account, and all reasonable attorneys' fees and expenses of Purchaser, if
any, relating to the exchange transaction and in no event shall Purchaser be
required to assume any liability thereunder.
                           (iv) During the period that the Escrow Account is
in existence, Seller shall not have any control, directly or indirectly, over
the funds placed in the Escrow Account, except as may be expressly provided
herein.
                           (v)  If, at the time of Closing, Seller shall not
have designated the Exchange Property, then if within forty-five (45) days
following Closing, Seller shall deliver to Purchaser and to Exchange Escrow
Agent a designation of an Exchange Property which Seller desires to acquire by
way of exchange for the Property transferred to Purchaser at Closing
("Designation"), the parties shall proceed as provided for herein. If there is
no timely Designation, then Exchange Escrow Agent, on the forty-sixth (46th) day
after Closing (or, if such day is a Saturday, Sunday or legal holiday, on the
first business day thereafter) shall disburse to Seller the Escrow Account and
all
<PAGE>

interest earned thereon shall be paid to Purchaser.
                           (vi) Any Designation of an Exchange Property shall
include an Exchange Contract, or thereafter Seller shall provide Purchaser with
an Exchange Contract, which Exchange Contract shall comply with the terms set
forth in Subparagraph 30.(a). The parties acknowledge that there may be multiple
Exchange Properties and that multiple Designations may be delivered, provided
that each meets the conditions set forth herein and the requirements of the
Internal Revenue Code Section 1031 and regulations thereunder.
                           (vii)  Upon receipt by Purchaser of an Exchange
Contract, it shall execute and deliver the Exchange Contract to the seller of
the Exchange Property ("Exchange Seller"), Seller and Exchange Escrow Agent.
Thereafter, Purchaser shall assign its interest in the Exchange Contract to
Exchange Escrow Agent, it being agreed that Purchaser shall not take title to
any Exchange Property.
                           (viii)  Upon Purchaser executing any Exchange
Contract, and in accordance therewith, Exchange Escrow Agent shall pay from the
Escrow Account to Exchange Seller, or such other party as is provided for in the
Exchange Contract, the amount of the deposit and all other monies required under
the Exchange Contract or otherwise related to the transaction.
                           (ix) Exchange Escrow Agent shall not be liable to
either Seller or Purchaser in connection with its performance as
Exchange Escrow Agent, except in the event of intentional
<PAGE>

wrongdoing or negligence. Exchange Escrow Agent is authorized only to do those
acts necessary and proper to effect the purpose of this Agreement.
                           (x)  The Exchange Escrow Agent shall use the
Escrow Account, for payment of the deposit and all other payments due under the
Exchange Contract to purchase the Exchange Property, plus closing costs, and for
no other purpose.
                           (xi) If the payment for the Exchange Property
shall exceed the amount of the Escrow Account, Seller either shall: (i) deposit
an amount equal to such excess with Exchange Escrow Agent no later than the day
of the Exchange Property Closing; or (ii) cause or direct that the funds
necessary to effectuate the Exchange Property Closing be paid directly to
Exchange Seller at the Exchange Property Closing.
                           (xii)  At the Exchange Property Closing, the
following shall be deposited or caused to be deposited with Exchange Escrow
Agent: (i) a deed for the Exchange Property from Exchange Seller as grantor to
Seller, as grantee; and (ii) any other documents or agreements necessary or
incidental to the acquisition or conveyance of the Exchange Property.
                           (xiii)  When all documents and funds called for
herein have been deposited with Exchange Escrow Agent and when a title policy
can be issued on the Exchange Property to Seller, subject only to title
exceptions approved by Seller, Exchange Escrow Agent shall record the deed,
disburse the funds and deliver all other documents to Seller. All expenses,
<PAGE>

reimbursements and prorations in connection with the Exchange Property shall be
governed by the provisions of the Exchange Contract, except as expressly set
forth herein.
                           (xiv)  Purchaser makes no warranty with respect to
the Exchange Property and Seller assumes all responsibility for title to the
Exchange Property being good and marketable. Seller agrees to indemnify
Purchaser and hold Purchaser harmless from any damages, liability, costs,
expenses, claims, losses or demands (including reasonable attorneys' fees and
costs of litigation including those for enforcing this indemnity), arising out
of or in any way related to the acquisition of the Exchange Property. If the
Exchange Property is subject to any mortgage, deed of trust or lease, Purchaser
shall assume no liability or obligation with respect to said mortgage, deed of
trust or lease. Purchaser makes no representations as to the tax consequences of
any aspect of this transaction.
                           (xv) If the Exchange Property as may be designated
by Seller is not conveyed to Seller within the earlier of: (i) one hundred
eighty (180) days after Closing; or (ii) the due date (determined with regard to
extensions) of Seller's federal income tax return for the taxable year in which
the transfer of the Property occurs or if no Exchange Property is designated
within forty-five (45) days following Closing, then the Escrow Account shall be
released to Seller, free of the escrow, and the obligations of Purchaser and
Exchange Escrow Agent shall end. Notwithstanding failure of the Exchange
Property to be conveyed
<PAGE>

to Seller as hereinabove set forth, the transfer of the Property to Purchaser
shall not be subject to recession or revocation by Seller or Purchaser for any
reason whatsoever.

         FOR AND IN CONSIDERATION of the mutual covenants hereinafter contained:

         31. AGREEMENT TO SELL AND PURCHASE.
                  (a) Seller hereby agrees to sell and convey, and Purchaser
hereby agrees to purchase, subject to the conditions set forth herein, those
certain plots, pieces or parcels of land ("Lands"), together with all buildings

                  (b) This sale includes, for no additional consideration, all
of the right, title and interest, if any, of Seller in and to the following:
                           (i)  All fixtures, equipment and articles of

Premises, and any replacements or substitutions therefor and additions thereto
("Personal Property"), all trade names and fictitious names used by Seller in
connection with any Premises ("Names"), and all documents, records and books of

                           (ii) Any land lying in the bed of any street, or
road open or proposed in front of, adjacent to, or adjoining any Premises, to
the center lines thereof, and any future award, if any, for damages to said
Premises by reason of change of grade of any street and all rights of way
appurtenant thereto ("Appurtenant Property"); and Seller shall execute and
deliver to Purchaser, at Closing or thereafter, on demand, all proper
instruments for the conveyance of such title and for the
<PAGE>

assignment and collection of any such award.
         The Premises, Personal Property, Names, Records and Appurtenant

"Properties".
         32. PURCHASE PRICE.
                  (a) The Closing for each Property will be conducted in phases
as each Property is improved with Improvements in accordance with the terms of
this Agreement. The purchase price for each Property (the "Purchase Price")
shall be an amount equal to the Capitalized Value (as hereinafter defined) for
such Property, subject to the closing adjustments and prorations described in
Paragraph 9.
                  (b) (i) The term "Capitalized Value" means, with respect to a
Property, an amount determined after Leasing Stabilization (as hereinafter
defined) for such Property having been achieved, by dividing (a) projected Net
Operating Income (as hereinafter defined) for each Property for the twelve (12)
month period succeeding the proposed Closing Date (as hereinafter defined) for
the applicable Property, by (b) the Applicable Cap Rate (as hereinafter
defined).
                           (ii)   The term "Net Operating Income" means, with
respect to a Property, the sum of (a) Gross Cash Receipts (as hereinafter
defined) for such Property, less (b) the Operating Expenses (as hereinafter
defined) for such Property.
                           (iii)  The term "Gross Cash Receipts" means all
projected revenues derived from Leases (as hereinafter defined)
<PAGE>

for such Property determined on an accrual basis for the twelve (12) month
period succeeding the proposed Closing Date for such Property, including from
(1) rental of space at such Property, (2) parking facilities at such Property,
(3) concessions, (4) other miscellaneous operating sources, and (5) rental
interruption insurance, if any, and shall not include deposits until the same
are forfeited by the person making such deposits or advance rentals until such
time as they are earned by Seller. Gross Cash Receipts shall not include
insurance loss proceeds (except for any proceeds from rental interruption
insurance) or any award or payment made by any governmental authority in
connection with the exercise of any right of eminent domain or any proceeds from
financing, sale, exchange or other disposition of such Property.
                           (iv)  The term "Operating Expenses" means, any and
all projected costs and expenses of operation and management of such Property
determined on an accrual basis for the twelve (12) month period succeeding the
proposed Closing Date for such Property, excluding any costs incurred as a
result of environmental testing and/or remediation, depreciation and other
non-cash expenditures, and including real estate taxes, insurance,
administrative and other management fees paid to third parties, maintenance and
repairs, incurred in connection with such Property and any and all other
expenses which under generally accepted accounting principles are regarded as
expenses of the Property as set forth in the Approved Project Pro-Forma
<PAGE>

(as hereinafter defined).
                           (v)  The "Applicable Cap Rate" shall be determined
by first establishing the Cost Cap (as hereinafter defined) and then selecting
the corresponding Applicable Cap Rate based on the following schedule:

         Cost Cap:                                        Applicable Cap Rate:

         10.6% and below                                       10.1%
         greater than 10.6% to 11%                             10.2%
         greater than 11% to  11.5%                            10.3%
         greater than 11.5%                                    10.4%
                           (vi)  The "Cost Cap" with respect to a Property
shall be determined once Leasing Stabilization has been achieved for such
Property by dividing (a) the projected Net Operating Income for such Property
for the twelve (12) month period succeeding the proposed Closing Date, by (b)
the Project Costs (as hereinafter defined) for such Property.
                           (vii)  The term "Project Costs" means an amount
equal to the sum of, without duplication, (1) all Hard Costs (as hereinafter
defined), (2) all Soft Costs (as hereinafter defined) and (3) an amount equal to
the product of (a) Land Value (as hereinafter defined) and (b) the number of
acres contained in the Property upon which the particular Improvements are being
constructed.
                           (viii)   The term "Soft Costs" means all costs
incurred in connection with the construction of Improvements and initial leasing
of a particular Property which are not properly categorized as Hard Costs or
Operating Expenses as more particularly set forth in the Approved Project
Pro-Forma (as
<PAGE>

hereinafter defined) and shall include, (1) construction period interest, (2)
lease brokerage commissions, (3) commitment fees for construction financing, (4)
title insurance, (5) surveys (including the "as-built" survey required by the
terms of Paragraph 4(f)) and plans, (6) appraisals, (7) permits, licenses and
temporary and permanent certificates of occupancy, (8) professional fees,
including architects, engineers, accountants and attorneys, (9) insurance,
including fire, extended coverage and all risk, (10) real estate taxes and
assessments, water rates, sewer charges and utility charges and (11) a
developer's fee in the amount of seven (7%) percent of the Hard Costs and Soft
Costs for such Property. Soft Costs shall not include any costs incurred as a
result of environmental testing and/or remediation.
                           (ix) The term "Hard Costs" means the costs and
expenses in respect of supplying goods, services, materials, labor (including
fringe benefits), equipment and fixtures for and in connection with the
construction of Improvements on a particular Property, including overhead equal
to the Applicable Overhead Percentage (as hereinafter defined) of Hard Costs and
profit equal to the Applicable Profit Percentage (as hereinafter defined) of
Hard Costs. The "Applicable Overhead Percentage" and "Applicable Profit
Percentage" shall be determined by first establishing the Hard Costs incurred
directly by McGarvey Construction Co., Inc. and the Hard Costs incurred by all
subcontractors for a particular Property and converting same to a
<PAGE>

percentage based upon the following fraction:
         McGarvey Construction Co., Inc. Hard Costs = the Percentage
         McGarvey Construction Co., Inc. Hard Costs
         plus all third party Subcontractor costs
and then selecting the corresponding Applicable Overhead Percentage and
Applicable Profit Percentage based on the following schedule:
                                            Applicable              Applicable
                                            Overhead                Profit
         Percentage                         Percentage              Percentage

40% or greater                                 10.0%                   10.0%

greater than 30% but
less than 40%                                   7.5%                    7.5%

                           (x) The term "Land Value" shall initially mean an
amount equal to Eighty-Five Thousand ($85,000.00) Dollars per acre. On the first
anniversary of the date of this Agreement and on each anniversary thereafter,
the Land Value shall be the greater of (A) Eighty-Five Thousand ($85,000.00)
Dollars per acre, or (B) a sum equal to Eighty-Five Thousand ($85,000.00)
Dollars per acre and that percentage of said amount as is equal to the percent
of increase, if any, in the Consumer Price Index for All Urban Consumers
(revised CPI-U) New York - Northeastern New Jersey, All Items revised 1982-1984
equals 100 published by the Bureau of Labor Statistics, U.S. Department of Labor
<PAGE>

(hereinafter called the "Index"), as of the date of this Agreement over the said
Index as of the anniversary of the date of this Agreement immediately preceding
the date of receipt of the Approved Project Pro-Forma for a particular Property;
provided, however, that in no event shall the Land Value be greater than Ninety
Thousand ($90,000.00) Dollars per acre (the "Land Value Limit"). Notwithstanding
the foregoing, the Land Value Limit shall not be applicable to Block 3500, Lot
49, Moorestown, New Jersey. In the event the Index hereinabove referred to
ceases to incorporate a significant number of the items set forth therein as of
the date hereof, or if a substantial change occurred in the manner of computing
such Index, then the Index shall be deemed to be the figure that would have
resulted had no change occurred in the manner of computing such Index. In the
event the Index (or a successor or substitute index) becomes unavailable, a
reliable governmental or other nonpartisan publication evaluating the
information theretofore used in determining the Index shall be used in lieu of
such Index. In the event of any dispute between the parties as to the manner of
computing any adjustment in the Land Value, or as to the Index to be used, or as
to any other matter arising under this Paragraph 2, such dispute shall be
resolved by arbitration as provided in Subparagraph (c) below. Purchaser shall
have the right to audit Seller's books and records to verify Seller's
calculation of Project Costs. Upon Purchaser's request, Seller shall promptly
deliver to Purchaser copies of relevant backup
<PAGE>

materials (including, but not limited to, contracts, correspondence and paid
invoices) reasonably required by Purchaser.
                  (c) Either party may at any time request arbitration for
determining the Hard Costs, Soft Costs, Applicable Overhead Percentage,
Applicable Profit Percentage, the Land Value, Index to be used and/or the
Applicable Cap Rate for a particular Property. The party requesting arbitration
shall do so by giving notice to that effect to the other party, specifying in
said notice the nature of the dispute, and said dispute shall be determined in
Trenton, New Jersey, by a panel of three arbitrators, in accordance with the
rules when obtaining of the American Arbitration Association (or any
organization which is the successor thereto) (the "AAA"). Each party shall,
within ten (10) days after the request for arbitration, each choose one
arbitrator and the two (2) arbitrators shall, within ten (10) days after
appointment, choose a third arbitrator. If the two (2) arbitrators chosen by
Seller and Purchaser do not agree upon a third (3rd) arbitrator within the time
provided, the third (3rd) arbitrator shall be appointed by the AAA. The award in
such arbitration may be enforced on the application of either party by the order
of judgment of a court of competent jurisdiction. The fees and expenses of any
arbitration shall be borne by the parties equally, but each party shall bear the
expense of its own attorneys and experts and the additional expenses of
presenting its own proof.

                           (iii)  If this Agreement is terminated due to

         34. CONSTRUCTION OF IMPROVEMENTS.
                  (a) Simultaneously with the execution and delivery of this
Agreement, Purchaser has entered into a certain Agreement of Sale with Seller
and certain affiliates of Seller (the "Agreement of Sale") relating to certain
property in the vicinity of a portion of the Properties (the "Adjacent
Properties"), more particularly described on Schedule "F" annexed hereto and
made a part hereof. As an inducement for Purchaser to execute and deliver this
Agreement, Seller covenants and agrees, that from and after the date hereof, at
anytime when the Adjacent Properties Leasing Threshold (as hereinafter defined)
is not satisfied, Seller shall not commence construction of any Improvements on
the Properties or any portion thereof provided, however, that Seller shall have
the right to complete any construction commenced in accordance herewith. Upon
breach of the aforesaid covenant by Seller, Purchaser shall have all remedies
given to it at law and in equity, including, the right to obtain injunctive
relief and/or to commence and prosecute an action for damages. "Adjacent
Properties Leasing Threshold" means, with respect to the Adjacent Properties,
leases for ninety
<PAGE>

(90%) percent of the aggregate Floor Area (as hereinafter defined) therein have
been executed and are in full force and effect (without landlord having declared
a default pursuant to such leases), the tenants thereof shall have accepted
delivery of possession of their respective premises and the security deposit, if
any, and at least one (1) months rent has been paid by each such tenant. "Floor
Area" means the floor area stated in square feet bounded by the exterior faces
of the exterior walls of a particular building. Any reference to Floor Area of a
building shall mean the floor areas of all levels or stories of such building,
excluding any roof, any interior basement level, any mechanical room, enclosed
or interior truck dock, interior common areas and areas used by the landlord for
storage, for housing meters and/or other equipment or for other purposes.
                  (b) At such times as the Adjacent Properties Leasing Threshold
is satisfied and Seller shall desire to construct Improvements on a Property, it
shall so notify Purchaser or its successors and/or assigns (the "Project
Commencement Notice"). In such event, Seller shall prepare a project pro-forma
budget for development of the particular Property (the "Project Pro-Forma")
generally in the form annexed hereto as Schedule "D" and made a part hereof and
deliver same to Purchaser or its successors and/or assigns within thirty (30)
days of the Project Commencement Notice. The Project Pro-Forma shall set forth
the estimate of all Project Costs of developing and constructing Improvements on
the particular Property, including, all Hard
<PAGE>

Costs; all Soft Costs; the Land Value; the time for commencement, completion and
rent-up; all details of the financing and equity funds required for the project;
the cost of tenant improvements; the percentage of office Floor Area and
warehouse Floor Area within all proposed tenant spaces; and anticipated lease
terms. Upon receipt of the Project Pro-Forma for a particular Property,
Purchaser shall have ten (10) days to approve or disapprove the Project
Pro-Forma. If Purchaser disapproves the Project Pro-Forma, it shall so notify
Seller, which notice shall specify the items to which Purchaser does not
approve. Seller shall revise the Project Pro-Forma in accordance with any
reasonable requirements of Purchaser and resubmit same to Purchaser for
Purchaser's approval within ten (10) days after receipt of Purchaser's notice of
disapproval. The revisions and resubmissions shall continue until Purchaser
shall have approved the Project Pro-Forma (the "Approved Project Pro-Forma").
                  (c) Within sixty (60) days after Purchaser approves the
Project Pro-Forma, Seller shall prepare and furnish to Purchaser complete
architectural drawings and specifications (the "Plans and Specifications") for
the construction of Improvements on the Property. The Plans and Specifications
shall be prepared by a licensed architect or engineer retained by Seller.
Purchaser agrees to review the Plans and Specifications and in each case to
approve same or to state what changes, if any, Purchaser requires therein within
thirty (30) days after receipt thereof. If Purchaser requires any changes,
Seller shall cause
<PAGE>

the Plans and Specifications to be revised in accordance with any reasonable
requirements of Purchaser and to resubmit same to Purchaser for Purchaser's
review within fifteen (15) days after receipt of Purchaser's changes. The
revisions and resubmissions shall continue until Purchaser shall have approved
the Plans and Specifications (said approved Plans and Specifications being
hereinafter called the "Approved Plans and Specifications"). Purchaser's
approval of the Plans and Specifications shall not constitute an opinion or
agreement by Purchaser that the Improvements are structurally sufficient or that
the Approved Plans and Specifications are in compliance with law (it being
agreed that such sufficiency and compliance are solely Seller's responsibility).
Seller shall provide Purchaser with two (2) sets of the Approved Plans and
Specifications and Seller and Purchaser shall execute counterparts thereof. The
Approved Plans and Specifications shall be final and shall not be changed by
Seller without the prior consent of Purchaser.
                  (d) Seller covenants and agrees that upon approval of the
Plans and Specifications, it shall, commence promptly and with due diligence
proceed to construct the Improvements on the Property in accordance with the
Approved Plans and Specifications, including, without limitation, utility lines,
drainage, lighting facilities, grading and paving, landscaping, approaches,
entrances, exits, ramps, sidewalks, roadways, curb cuts, loading areas,
platforms, service roads and all buildings required to be constructed pursuant
to the Approved Plans and
<PAGE>

Specifications. The construction work shall be done in a first class, good and
workmanlike manner and in compliance with all applicable laws, orders and
regulations of federal, state, county and municipal authorities having
jurisdiction. Seller, at its sole cost and expense, shall obtain or cause to be
obtained all building permits, licenses, temporary and permanent certificates of
occupancy and other governmental approvals which may be required to permit the
construction of the Improvements in accordance with the Approved Plans and
Specifications and the use or occupancy thereof.
                  (e) Purchaser may, on reasonable prior notice to Seller, visit
the job site to inspect the progress and performance of the work and the
materials being incorporated into the Improvements.
                  (f) Within ten (10) days prior to Closing but not later than
thirty (30) days after Substantial Completion of construction of the
Improvements on a Property, Seller shall, at its sole cost, deliver to Purchaser
an accurate "as built" survey of the Improvements certified to Purchaser and its
designees by a duly licensed surveyor including the information set forth on
Schedule "G", together with three (3) sets of "as built" plans of the
Improvements, including, without limitation, architectural and mechanical plans.
                  (g) Seller shall, at its own expense, maintain or cause to be
maintained in force a policy or policies of insurance written by one or more
responsible insurance carriers acceptably
<PAGE>

                                                 effect for two (2) years after
                                                 completion);

                                            (4)  "XCU" Hazard Endorsement, if
                                                 applicable;

                                            (7)  Contractual Liability

insurer(s) specifically recognize and insure the obligations undertaken by
Seller pursuant to this Agreement and shall name Purchaser as an additional
insured. Prior to commencement of any construction, Seller shall deliver a
certificate of insurance
<PAGE>

evidencing the existence in force of such policy or policies of insurance. Such
certificate shall provide that such insurance will not be canceled or materially
amended unless twenty (20) days prior written notice is given to Purchaser.
                  (h) Seller covenants and agrees, at its sole cost and expense,
to promptly make, or cause to be made, all repairs and replacements to the
applicable work arising from defective labor and/or materials during the period
commencing on the later of (1) final completion of such Improvements and (2) the
Closing Date of a particular Property, and terminating on the date which is one
(1) year therefrom.
                  (i) Seller shall give Purchaser at least sixty (60) days prior
notice of the date of Substantial Completion (the "Substantial Completion
Notice") for a particular Property.
                  (j) Seller has advised Purchaser that it has commenced
construction of 2 buildings on a portion of the Property known as 41 Twosome
Drive and 915 North Lenola Road. Within thirty (30) days from the date of this
Agreement, Seller shall furnish Purchaser with the Project Pro-Forma and the
Plans and Specifications for such Properties. Upon receipt of such Project
Pro-Forma and Plans and Specifications, Purchaser shall have ten (10) days to

which notice shall specify the items to which Purchaser does not approve. Seller
shall use its best efforts to revise the Project Pro-Forma and/or Plans and
Specifications, as the case may be, in accordance with any
<PAGE>

reasonable requirements of Purchaser and resubmit same to Purchaser for
Purchaser's approval within ten (10) days after receipt of Purchaser's notice of

shall have approved the Project Pro-Forma and Plans and Specifications for such
Properties. Notwithstanding the foregoing, Purchaser agrees not to unreasonably
withhold or delay its approval if the Plans and Specifications for such
Properties are the same or substantially similar to the properties commonly
known as 30 Twosome Drive, 40 Twosome Drive and 50 Twosome Drive. In addition,
Purchaser shall not unreasonably withhold or delay its consent to the Project
Pro-Forma for such Properties, if same is generally consistent with the project
pro-forma for 30 Twosome Drive, 40 Twosome Drive and 50 Twosome Drive and in the
form annexed hereto as Schedule "D".
         35. TITLE.
                  (a) Seller shall convey title to each Property which it owns
and Purchaser shall accept Marketable Title (as hereinafter defined), subject
only to the encumbrances set forth on Schedule "H" ("Permitted Encumbrances").
Marketable Title shall mean that fee title to each of the Properties is vested
in Seller and shall be insured as such by a title company selected by Purchaser
(herein referred to as the "Title Company") at standard rates; and that
Purchaser shall not incur any damage, cost or expense resulting from any
encroachment or overlap affecting any of the Properties. Title Company shall
certify
<PAGE>

that Seller has the right, authority and power to enter into and to perform its
obligations hereunder. The legal description in the Binder (as hereinafter
defined) and in the Deed (as hereinafter defined) shall be in accordance with
current surveys showing the completed Improvements on a particular Property
satisfactory to Title Company and Purchaser.
                  (b) Upon receipt of the Approved Project Pro-Forma, Purchaser,
at its cost and expense, shall order a title insurance binder for the applicable
Property (herein referred to as the "Binder") and prior to the expiration of the
Due Diligence Period (as hereinafter defined) shall deliver to Seller's attorney
notice of any objections to title which are not Permitted Encumbrances. After
the execution hereof, without Purchaser's prior consent, which consent shall not
be unreasonably withheld or delayed, no further liens, encumbrances, easements
or restrictions shall be created or filed ("Subsequent Encumbrances") on or with
respect to any of the Properties except for construction mortgages the proceeds
of which are used for construction of Improvements on a particular Property.
Each Binder, at the request of Purchaser, shall contain the following
endorsements so that at Closing, Title Company will issue an Owner's Policy of
Title Insurance (American Land Title Association Owner's Policy - 1992 or
equivalent, in Purchaser's sole judgment), in the full amount of the Purchase
Price for such Property (the "Title Policy" or "Title Policies"):
                           (i)  a zoning endorsement certifying that the
<PAGE>

insured Property is not subject to any ordinance, regulation or restriction
which in any way would prohibit or restrict the construction, maintenance and/or
use of the insured Property for its present use;
                           (ii) an endorsement insuring contiguity between or
among all of the tracts or parcels of land comprising the insured
Property;
                           (iii)  an endorsement deleting any coverage
exclusions with respect to creditor's rights; and
                           (iv)  an endorsement affirmatively insuring access
to public streets, highway and roadways.
         If any Binder discloses any exceptions, liens, encumbrances, defects or
objections other than the Permitted Encumbrances or if, after execution hereof,
a Subsequent Encumbrance shall be placed against any of the insured Property
(herein collectively called the "Title Defect(s)"), then Purchaser shall have
the right to: (i) require Seller to use best efforts to cure any such Title
Defects (except that Seller shall be obligated to cure any Title Defects which
can be removed solely by the payment of a sum of money); (ii) attempt to cure
any such Title Defect; (iii) accept such title as Seller shall be able to convey
and proceed to Closing without reduction in the Purchase Price; (iv) cause a
title report and title insurance policy to be issued by another title company
without such Title Defect; (v) elect not to purchase such insured Property and
to proceed to purchase the remaining Properties, provided, however, if Seller
gives notice
<PAGE>

to Purchaser within five (5) days after Purchaser's election under this
subparagraph (v), that Seller intends to cure such Title Defects and thereafter
cures such Title Defects in accordance with the terms of this Agreement within
thirty (30) days after receipt of notice from Purchaser of its election under
this subparagraph (v), then such Property shall be included in the sale pursuant
to the terms of this Agreement; and/or (vi) declare this Agreement null and
void, whereupon Purchaser shall be entitled to the return of the Letter of
Credit. The right of Purchaser to terminate this Agreement may be exercised
following the exercise of its other rights hereunder. The time of Closing shall
be extended for a period of up to sixty (60) days, if necessary, to permit
Purchaser to pursue the exercise of its rights hereunder.
                  (c) If at Closing there are liens or encumbrances against any
of the Properties other than Permitted Encumbrances, Seller may use any portion
of the Purchase Price for such Property to satisfy same, provided Seller, at
Closing, either shall: (1) deliver to Purchaser instruments in recordable form
sufficient to satisfy such liens or encumbrances of record, together with the
cost of recording or filing said instruments; or (2) deposit with Title Company
sufficient monies acceptable to Title Company to insure obtaining and recording
of such satisfactions and the issuance of a Title Policy for such Property to
Purchaser free and clear of any such liens or encumbrances, but only to the
extent that such liens or
<PAGE>

encumbrances are in favor of and held by institutional lenders. The existence of
any such liens or encumbrances shall not be deemed objections or exceptions to
title if Seller shall comply with the foregoing requirements.
                  (d) If a search of title discloses judgments, bankruptcies or
other returns against other persons or entities having names the same as or
similar to that of Seller or any predecessor in title, Seller, on request, shall
deliver to Title Company, an affidavit showing that such judgments, bankruptcies
or other returns are not against Seller or such predecessors in interest of
Seller.
         36. REPRESENTATIONS, WARRANTIES AND COVENANTS.

obligation to Tenant assumed by Purchaser or any advance rental credited to
Purchaser. After Seller shall receive notice of a claim that may give rise to an
indemnity hereunder, Seller shall notify Purchaser; provided, however, the
failure to give any notice shall not relieve Purchaser from any liability
hereunder unless such failure impairs the right to defend such action. In the
event any claim is brought against Seller with respect to which Purchaser may
have liability under the indemnity agreement contained in this Paragraph 7.(d),
the claim may, upon written agreement of Purchaser that it is obligated to
indemnify against the particular claim under the indemnity contained herein, be
settled by Purchaser with the prior written consent of Seller, which shall not
be unreasonably withheld.
                  (e) Seller agrees not to apply or return any security deposit
in whole or in part. At the Closing, Seller shall turn
<PAGE>

         38. CLOSING.
                  (a) Each Closing shall occur at 10:00 a.m. at the offices of
Cole, Schotz, Meisel, Forman & Leonard, P.A., Court Plaza North, 25 Main Street,
Hackensack, New Jersey, on the date which is fifteen (15) days after
satisfaction or waiver of all conditions and contingencies set forth herein with
regard to such Property, or at such other date, time and/or place as the parties
may agree upon; provided, however, that if such date shall be a Saturday, Sunday
or legal holiday, then Closing shall take place on the first business date
thereafter (herein referred to as the "Closing" and the "Closing Date"
respectively). Notwithstanding the foregoing, if despite achieving Leasing
Stabilization with respect to a particular Property, such Property is not
Substantially Leased (as hereinafter defined) on or before the date Seller shall
give Purchaser the Substantial Completion Notice, then Seller may, at its
option, by notice to Purchaser given with the Substantial Completion Notice,
elect to extend the date for Closing to a date on or before the date which is
one (1)
<PAGE>

year from the date of achieving Leasing Stabilization (the "Extended Closing
Date"). If Seller provides notice of the Extended Closing Date, then provided
all of the conditions precedent are satisfied, Closing for the particular
Property shall occur on the date which is thirty (30) days after Seller notifies
Purchaser of the proposed Closing Date, but in no event later than one (1) year
from the date of achieving Leasing Stabilization. If Seller fails to give such
notice of the proposed Closing Date, the Closing Date shall be the date which is
one (1) year from the date of achieving Leasing Stabilization. If Seller fails
to give Purchaser notice of the Extended Closing Date in accordance with the
terms of this Paragraph 8(a), then Seller shall be deemed to have waived the
right to extend the Closing. The term "Substantially Leased" shall mean, with
respect to each Property which has been developed with Improvements, (a) leases
complying with the terms and conditions set forth in Paragraph 7 for
substantially all of the Floor Area therein have been executed and are in full
force in effect, and (b) no default by either party to such leases has occurred
and is continuing, or no event has occurred and is continuing which, with the
giving of notice or the passage of time or both, would constitute a default
under such leases.

delivered:

                  (d) The words "Closing", "title closing", "Closing of title",
"delivery of deed" and words of similar import are used interchangeably in this
Agreement, as the sense of text indicates, to mean the Closing of title for each

         39. CLOSING ADJUSTMENTS.
                  (a)  The following are to be apportioned as of the
Closing Date of each Property:
                           (i)  real property taxes;
                           (ii) water rates and charges;
                           (iii)  sewer taxes and rents;
                           (iv) all base rent payments;
<PAGE>

                           (v)  common area and other additional rent
charges, if any;
                           (vi) fuel oil on hand, determined at Seller's
cost;
                           (vii)  insurance premiums on transferable
policies, if any, approved by Purchaser; and
                           (viii)  annual license, permit and inspection
fees, if any, provided that Seller's rights thereunder (or with respect thereto)
are transferable to Purchaser.
                  (b) (i) Apportionment of real property taxes, water rates and
charges and sewer taxes and rents shall be made on the basis of the fiscal year
for which assessed solely to the extent actually received by Seller from Tenants
or actually paid or payable by Seller. If the Closing Date shall occur before
any or all of the foregoing are fixed, the apportionment of real property taxes
shall be made on the basis of the tax rate for the preceding year applied to the
latest assessed valuation. After the final real property taxes, water rates and
charges and sewer taxes and rents are fixed, Seller and Purchaser shall make a
recalculation of the apportionment of same, and Seller or Purchaser, as the case
may be, shall make an appropriate payment to the other based on such
recalculation.
                           (ii) If at the time for the delivery of the Deeds,
any of the Premises or any part of any of them shall be or shall have been
affected by an assessment or assessments (including special and/or added) which
are or may become payable in annual
<PAGE>

installments of which the first installment is then due or has been paid, then
for the purposes of this Agreement all the unpaid installments of any such
assessment, including those which are to become due and payable after the
delivery of the applicable Deed for the affected Premises, shall be deemed to be
due and payable and to be liens upon such Premises affected thereby and shall be
paid and discharged by Seller upon the delivery of the Deed for the Premises. If
any assessment with respect to any Premises is unconfirmed at the time of
Closing, or if subsequent to Closing any assessment, including special or added,
is determined to be incorrect, then, immediately after the amount of the
assessment has been established, or the confirmed assessment corrected as a
result of a prior error, Seller shall make an appropriate payment to Purchaser
within ten (10) days of the tax assessor's calculation of the assessment.
Notwithstanding the foregoing, if Tenants of any Premises are obligated under a
written lease for the payment of the entire assessment (confirmed and/or
unconfirmed), then with respect to such assessment, Purchaser shall seek payment
from the Tenants, and any assessment not otherwise the obligation of the Tenants
shall be the obligation of Seller. Seller shall indemnify and hold Purchaser
harmless from and against all costs and expenses, including reasonable attorneys
fees, incurred by Purchaser in connection with Seller's failure to perform
Seller's obligation under this Paragraph 9(b)(ii).
                  (c)  If there shall be any water meters on any of the
<PAGE>

Properties (other than meters measuring water consumption costs which are the
obligation of Tenants to pay), Seller shall furnish readings to a date not more
than ten (10) days prior to the Closing Date, and the unfixed water rates and
charges and sewer taxes and rents, if any, based thereon for the intervening
time, shall be apportioned on the basis of such last readings.
                  (d) The amount of unpaid taxes, assessments, water charges and
sewer rents which Seller is obligated to pay and discharge, with interest and
penalties thereon to the fifth (5th) day after the Closing Date, at the option
of Seller, may be allowed to Purchaser out of the Purchase Price, provided that
official bills therefor with interest and penalties thereon are furnished by
Seller at the Closing.
                  (e) If any refund of real property taxes, water rates and
charges or sewer taxes and rents is made after the Closing Date for a period
prior to the Closing Date, the same shall be applied first to the costs incurred
in obtaining same and second to the refunds due to Tenants by reason of the
provisions of their respective Leases. The balance, if any, of such refund shall
be paid to Seller (for the period prior to the Closing Date) and Purchaser (for
the period commencing with the Closing Date).
                  (f) To the extent that Seller receives rent payments after the
Closing Date for any period from and after the Closing Date, the same shall be
held in trust and immediately paid to Purchaser.
<PAGE>

                  (g) All rent payments received by Seller or Purchaser after
Closing shall be applied firstly against out-of-pocket costs of collection, then
to rents due and owing by such Tenant for the periods from and after Closing and
thereafter against rents due and owing prior to Closing in inverse order of due
date.
                  (h) To the extent that rent payments are received by Purchaser
after the Closing Date with respect to a period prior to the Closing Date, the
amount of such rents for the period ending on the date preceding the Closing
Date, shall be paid to Seller by Purchaser as and if received after the Closing
Date, but not more often than once a month.
                  (i) All realty transfer fees and charges (other than recording
fees for the Deeds) shall be paid by Seller at Closing.
         40. RISK OF LOSS.
                  (a) Seller assumes the risk of loss or damage to all of the
Properties beyond ordinary wear and tear until delivery of a Deed for the
applicable Property to Purchaser and shall notify Purchaser forthwith upon the
occurrence of any such casualty ("Casualty Notice"). In the event of any
casualty in which the Casualty Threshold (as hereinafter defined) is not
established, or in the event of a casualty in which the Casualty Threshold is
established and if Purchaser elects to complete the purchase of the particular
Property hereunder, Seller shall restore and repair the damaged Property to its
condition immediately preceding such casualty and in accordance with its
obligations
<PAGE>

pursuant to Leases, and without a change in the Purchase Price
for the particular Property.
                  (b) If, prior to the Closing Date, any Property or Properties
shall be damaged by fire or other casualty and the estimated cost of repair
and/or restoration shall exceed twenty-five (25%) percent of the Purchase Price
of such damaged Property herein or reasonably shall be estimated to require more
than one hundred eighty (180) days to repair or restore (collectively, "Casualty
Threshold"), Purchaser may, by notice to Seller, elect either (i) not to
purchase such Property, or (ii) to terminate this Agreement. If this Agreement
is so terminated the Letter of Credit forthwith shall be returned to Purchaser.
Purchaser shall notify Seller of its decision within forty-five (45) days of
receipt of the Casualty Notice, which shall include the amount of insurance
coverage, the amount of insurance received, if any, the reasonably estimated
cost of repairs and the reasonably estimated time in which to complete said
repairs, and the applicable Closing shall be postponed accordingly.
                  (c) Notwithstanding the foregoing, any proceeds of loss of
rent insurance for a casualty occurring prior to the Closing Date, whether
received prior to or following the Closing, shall be apportioned as of the
Closing Date.
         41. CONDEMNATION. In the event that, prior to Closing, all or any
portion of any or all of the Properties shall be condemned or taken as the
result of the exercise of the power of eminent domain, or by deed in lieu
thereof (collectively, a "Taking"), or
<PAGE>

if such proceedings shall have commenced or shall be threatened, Seller promptly
shall notify Purchaser ("Taking Notice"). Purchaser, in its sole judgment, shall
notify Seller within sixty (60) days following receipt of the Taking Notice,
that: (1) the remaining portion of a specific Property is not suitable or
economically viable for its intended use of the affected Property, in which
event Purchaser may terminate this Agreement with respect to such Property; or
(2) the remaining portion of the affected Property is suitable and economically
viable for its intended use, in which event Closing shall proceed and Purchaser
and Seller shall have the right to participate jointly in the condemnation
proceedings and the proceeds thereof shall belong to Seller, subject to the
rights of mortgage holders, but Purchaser shall be entitled to a credit against
the Purchase Price in an amount equal to said proceeds, unless such condemnation
proceedings shall be pending on the Closing Date, in which event there shall not
be any credit and at Closing, Seller shall assign all its right, title and
interest in and to said proceedings and award to Purchaser. Notwithstanding
anything to the contrary contained herein, if there is a Taking of two (2) or
more Properties, Purchaser may, upon notice to Seller, terminate this Agreement
without further liability hereunder on the part of either party, except that the
Letter of Credit forthwith shall be returned to Purchaser.
         42. APPROVALS FOR TRANSFER.  In the event that any
Governmental Authority shall have an ordinance, law, rule,
<PAGE>

regulation or other requirement requiring a new Certificate of Occupancy or
other governmental authorization to be issued in connection with the transfer of
title to any of the Properties, or in the event that on the Closing Date there
is any such requirement, then and in any of such events, Seller shall use its
best efforts, at its sole cost and expense, to obtain and deliver to Purchaser,
the Certificate of Occupancy or other governmental authorization.
         43. DUE DILIGENCE PERIOD.
                  (a) Commencing on the date of approval of the Approved Project
Pro-Forma for a particular Property through the period ending forty-five (45)
days thereafter (the "Due Diligence Period"), Purchaser may perform, or cause to
be performed, tests, investigations and studies of or related to any or all of
the Properties which are the subject of the Approved Project Pro-Forma,

<PAGE>

Purchaser shall repair and restore any portion of the surface of any of the
Properties disturbed by Purchaser, its agents, representatives or contractors
during the conduct of any tests and studies to substantially the same condition
as existed prior to such disturbance. Such right of inspection and the exercise
of such right shall not constitute a waiver by Purchaser of the breach of any
representation, warranty, covenant or agreement of Seller which might, or
should, have been disclosed by such inspection.
                  (b) During the Due Diligence Period, Purchaser, its agents,
representatives and contractors, shall have unlimited access to all of the
Properties which are the subject of the Approved Project Pro-Forma and other
information pertaining thereto in the possession or within the control of Seller
for the purpose of performing such studies, tests, borings, investigations and
inspections for the purposes described in this Paragraph. Seller shall cooperate
with Purchaser in facilitating its due diligence inquiry and shall obtain, and
use its best reasonable efforts to obtain, any consents that may be necessary in
order for Purchaser to perform same. In addition, Seller will deliver to
Purchaser promptly after request, true and complete copies of all test borings,
Environmental Documents, surveys, title materials and engineering and
architectural data and the like relating to any such Properties that are in
Seller's possession or under its control. In the event any additional materials
or information comes within Seller's possession or

control after the date of this Agreement, Seller promptly shall submit true and
complete copies of the same to Purchaser. Seller shall notify Purchaser of any
dangerous conditions on any of the Properties, including, without limitation,
conditions which due to the nature of the borings, studies, investigations,
inspections or testing to be performed by or on behalf of Purchaser may pose a
dangerous condition to Purchaser or Purchaser's agents, representatives or
contractors.
                  (c) Purchaser shall obtain, or cause its contractors, agents
and representatives to obtain, liability insurance in an amount equal to One
Million ($1,000,000.00) Dollars on a per occurrence and aggregate basis on
account of personal injury to one or more persons and property damage with
respect to Purchaser's activities and entry onto the Properties. The policy
shall name Seller as additional insureds. In addition, Purchaser agrees to
indemnify and hold Seller harmless from any damage or injury to persons or
property arising out of or in connection with Purchaser or its contractors,
agents or representatives entering upon the Properties.
                  (d) Purchaser may terminate this Agreement with respect to a
Property set forth in the Approved Project Pro-Forma for any reason or for no
reason by notice to Seller given within the Due Diligence Period. In the event
Purchaser terminates this Agreement with respect to such Property during the Due
Diligence Period, this Agreement shall be null and void with respect to such
Property, copies of any reports or studies prepared by third
<PAGE>

parties as part of Purchaser's investigations during the Due Diligence Period
with respect to such Property (if expressly permitted by such third party),
shall be delivered to Seller (except, if this Agreement is terminated as a
result of Seller's breach hereof). In the event Purchaser does not terminate
this Agreement by the end of the Due Diligence Period, Purchaser shall be deemed
to have elected not to terminate this Agreement with respect to such Property.
         44. ENVIRONMENTAL PROVISIONS.

negotiate the terms and conditions of the transactions contemplated in the

23 shall continue to be effective and shall remain in full force and effect. If
Purchaser does not elect to pursue such Solicitation, then Principals may, with
respect to the transactions set forth in the Solicitation Notice, pursue such

         56. GUARANTY.
                  (a) Guarantors hereby, jointly and severally, guarantee to
Purchaser, its successors and assigns the full, due and timely completion of
construction of all Improvements in the manner required by the Approved Plans
and Specifications from time to time and in accordance with the provisions of
this Agreement including any modifications or amendments hereto, without any
further writing, and the costs for enforcing this Guaranty (collectively, the
"Obligations").
                  (b) This is a guaranty of payment and performance and not of
collection. The obligations of Guarantors hereunder are independent of the
obligations of Seller, and a separate action or actions may be brought and
prosecuted against Guarantors, regardless whether action is brought against
Seller or whether Seller are joined in any such action or actions.
                  (c) Guarantors agree that the obligations of Guarantors under
this Paragraph 26 are primary, absolute and unconditional, irrespective of the
value, genuineness, validity, regularity or enforceability of any of the
Agreement or any instrument referred to herein, or any substitution, release or
exchange of any other guaranty of or security for the Obligations, and, to the
fullest extent permitted by applicable
<PAGE>

law, irrespective of any other circumstance whatsoever (including, without
limitation, personal defenses of Seller) which might otherwise constitute a
legal or equitable discharge or defense of a surety, guarantor or co-obligor, it
being the intent of this Paragraph 26 that the obligations of Guarantors
hereunder shall be primary, absolute and unconditional under any and all
circumstances. Without limiting the generality of the foregoing, it is agreed
that the occurrence of any one or more the following shall not alter or impair
the liability of Guarantors hereunder:
                           (i)  at any time or from time to time, without
notice to or consent of Guarantors, the time for any performance of or
compliance with the Obligations shall be extended, or such performance or
compliance shall be waived;
                           (ii) any modification of or amendment to the
Agreement;
                           (iii) the existence of any claim, set-off or
other right which Guarantors may have at any time against Purchaser, Seller or
any other person or entity, whether in connection herewith or with any unrelated
transaction;
                           (iv) any of the acts required or contemplated in
any of the provisions of the Agreement or other instruments
referred herein shall be done or omitted;
                           (v)  the maturity of any of the Obligations shall
be accelerated or extended, or any of the Obligations shall be
modified, supplemented or amended in any respect or any right
<PAGE>

under the Agreement or other instruments referred to herein shall be waived or
extended or any other guaranty of the Obligations or any security therefor shall
be released or exchanged in whole or in part or otherwise dealt with;
                           (vi) Purchaser releases or substitutes any one or
more of any Seller, endorses or guarantors of the Obligations;
                           (vii) any of the Obligations shall be
determined to be void or voidable or shall be subordinated to the
claims of any person; or
                           (viii)   there shall be occur any insolvency,
bankruptcy, reorganization or dissolution of Seller(s) or other
Guarantor.
         With respect to their obligations hereunder, Guarantors hereby
expressly waive diligence, presentment, demand of payment, protest and all
notices whatsoever and any requirement that Purchaser exhaust any right, power
or remedy or proceed against any person under the Agreement or other instruments
referred to herein, or against any collateral or other person under any other
guaranty of, or security for, or obligation relating to, any of the Obligations.
                  (d) The obligations of Guarantors under this Paragraph 26
shall be automatically reinstated if and to the extent that for any reason any
payment or performance by or on behalf of any persons in respect of the
Obligations is rescinded or must be otherwise restored by Purchaser or any other
holder or recipient of payment or performance of the Obligations, whether as a
result
<PAGE>

of any proceedings in bankruptcy or reorganization or otherwise, and Guarantors
agree that they will pay to Purchaser on demand all reasonable out-of-pocket
costs and expenses (including, without limitation, fees of counsel) incurred by
Purchaser in connection with such rescission or restoration, including any such
costs and expenses incurred in defending against any claim alleging that such
payment constituted a preference, fraudulent transfer or similar payment under
any bankruptcy, insolvency or similar law.
                  (e) Without limiting the generality of the provisions of this
Paragraph 26, Guarantors hereby specifically waive: (a) promptness, diligence,
notice of acceptance and any other notice with respect to the Obligations; (b)
any requirement that Purchaser protect, secure or insure any lien or any
property subject thereto or exhaust any right or take any action against Seller
or any collateral or undertake any marshalling of assets; (c) the right to
direct the order of enforcement or remedies, (d) any defense arising by reason
of any claim or defense based upon an election of remedies by Purchaser which in
any manner impairs, reduces, releases or otherwise adversely affects its
subrogating, contribution or reimbursement rights or other rights to proceed
against Seller or any collateral; (e) any duty on the part of Purchaser to
disclose to Guarantors any matter, fact or thing relating to the business,
operation or condition of the Properties or Seller and their assets now known or
hereafter known by Purchaser; and (f) all presentments, demands for
<PAGE>

performance, notices of nonperformance, protests, notices of protest, notices of
dishonor, and notices of acceptance of the guaranty provided for in this
Paragraph 26 and the existence, creation or incurrence of new or additional
indebtedness.
         57. ROLLBACK TAXES. Any "rollback taxes" assessed or to be assessed
against any Premises identified on Schedule "A" pursuant to the Farmland
Assessment Act of 1964, N.J.S.A. 54:4-23.1, et seq., shall be paid by Seller. If
rollback taxes will be due with respect to any Premises but are not assessed
against a Property at a Closing, a good-faith estimate of the amount of same
shall be obtained by the parties from the tax assessor of the Township of
Moorestown, at least twenty-four (24) hours prior to Closing, and Seller shall
pay one hundred twenty-five (125%) percent of the amount of said estimate from
the proceeds at Closing into escrow to be held by Title Company until such time
as the rollback tax assessment against the respective Premises is made. Upon
Title Company's receipt of notice from Purchaser that said rollback taxes have
been assessed against the Premises, Title Company shall, within three (3)
business days thereof, pay said taxes to the Township of Moorestown. In the
event the amount of the monies being held in escrow by Title Company are not
sufficient to cover payment of said rollback taxes, then Seller shall promptly
pay to Purchaser any additional monies that are due and payable by Seller in
accordance with the terms and provisions of this Paragraph; and in the event the
amount of the escrow monies are in excess of the amount of said rollback taxes,
<PAGE>

then Title Company shall disburse the remaining balance of the escrow funds to
Seller after the amount of the escrow monies due to Purchaser have been
disbursed to the Township of Moorestown, in accordance with the terms and
provisions of the immediately proceeding sentence. Seller shall indemnify and
hold Purchaser harmless from and against all costs and expenses, including
reasonable attorneys fees, incurred by Purchaser in connection with Seller's
failure to perform Seller's obligations under this Paragraph 27.
         58. SELLER'S RIGHT TO EXCHANGE PROPERTY.
                  (a) (i) Seller shall have the right, exercisable at least
thirty (30) days prior to Closing, to elect to exchange the Property for other
property of like kind ("Exchange Property") pursuant to Section 1031 of the
Internal Revenue Code of 1986, as amended.
                           (ii) If Seller elects to effect any exchange, it
shall notify Purchaser as to all details thereof, and Purchaser shall execute a
contract to purchase the Exchange Property in a form satisfactory to Seller
(hereinafter called the "Exchange Contract"), and immediately thereafter shall
assign all of its right, title and interest in and to the Exchange Contract to
the Exchange Escrow Agent, as hereinafter defined. The funds required to pay the
deposit under the Exchange Contract shall be provided to Purchaser by Seller or
Exchange Escrow Agent. The Exchange Contract shall provide for the right of
assignment by Purchaser to Exchange Escrow Agent and/or Seller without
<PAGE>

recourse, and that the seller of the Exchange Property shall look only to the
deposit monies thereunder as liquidated damages, there being no liability on the
part of Purchaser to said seller. Purchaser shall not be obligated to execute an
Exchange Contract which would require Purchaser to be personally liable on any
indebtedness or to incur any cost or expense which would increase Purchaser's
liability beyond that liability incurred by Purchaser hereunder.
                           (iii)  In no event, however, shall the closing of
title to the Property be delayed due to the inability of Seller to select an
Exchange Property or close title thereto.
                  (b) (i) If Seller shall elect to exchange the Property
pursuant to this Paragraph, whether or not an Exchange Property has been
designated, as herein set forth, the Purchase Price, exclusive of the
satisfaction of liens, payment of closing costs and other permitted expenses,
shall be deposited with the Exchange Escrow Agent ("Escrow Account"), subject to
the Exchange Escrow Agent executing an agreement reasonably satisfactory to
Purchaser whereby Exchange Escrow Agent agrees to be bound by the terms and
conditions of this Paragraph 28, and shall not be paid to Seller at Closing. The
Escrow Account shall be held by Exchange Escrow Agent in an interest bearing
account, pursuant to the terms hereof. The interest earned upon the Escrow
Account while being held by Exchange Escrow Agent shall be added to the Escrow
Account and shall be paid to Seller at the closing of the Exchange Property.
<PAGE>

                           (ii) Purchaser appoints its title insurance
company or such other title insurance company or other entity as Purchaser
reasonably may designate, its agent, in order to effectuate the Exchange (the
"Exchange Escrow Agent"). Purchaser and Seller shall cooperate with each other
and Exchange Escrow Agent and promptly shall sign and deliver to Exchange Escrow
Agent all documents reasonably deemed necessary by Seller in order to qualify
this transaction pursuant to Internal Revenue Code Section 1031.
                           (iii)  Seller shall pay all fees relating to the
Escrow Account, and all reasonable attorneys' fees and expenses of Purchaser, if
any, relating to the exchange transaction and in no event shall Purchaser be
required to assume any liability thereunder.
                           (iv) During the period that the Escrow Account is
in existence, Seller shall not have any control, directly or indirectly, over
the funds placed in the Escrow Account, except as may be expressly provided
herein.
                           (v)  If, at the time of Closing, Seller shall not
have designated the Exchange Property, then if within forty-five (45) days
following Closing, Seller shall deliver to Purchaser and to Exchange Escrow
Agent a designation of an Exchange Property which Seller desires to acquire by
way of exchange for the Property transferred to Purchaser at Closing
("Designation"), the parties shall proceed as provided for herein. If there is
no timely Designation, then Exchange Escrow Agent, on the
<PAGE>

forty-sixth (46th) day after Closing (or, if such day is a Saturday, Sunday or
legal holiday, on the first business day thereafter) shall disburse to Seller
the Escrow Account and all interest earned thereon shall be paid to Purchaser.
                           (vi) Any Designation of an Exchange Property shall
include an Exchange Contract, or thereafter Seller shall provide Purchaser with
an Exchange Contract, which Exchange Contract shall comply with the terms set
forth in Subparagraph 28.(a). The parties acknowledge that there may be multiple
Exchange Properties and that multiple Designations may be delivered, provided
that each meets the conditions set forth herein and the requirements of the
Internal Revenue Code Section 1031 and regulations thereunder.
                           (vii)  Upon receipt by Purchaser of an Exchange
Contract, it shall execute and deliver the Exchange Contract to the seller of
the Exchange Property ("Exchange Seller"), Seller and Exchange Escrow Agent.
Thereafter, Purchaser shall assign its interest in the Exchange Contract to
Exchange Escrow Agent, it being agreed that Purchaser shall not take title to
any Exchange Property.
                           (viii)  Upon Purchaser executing any Exchange
Contract, and in accordance therewith, Exchange Escrow Agent shall pay from the
Escrow Account to Exchange Seller, or such other party as is provided for in the
Exchange Contract, the amount of the deposit and all other monies required under
the Exchange Contract or otherwise related to the transaction.
<PAGE>

                           (ix) Exchange Escrow Agent shall not be liable to
either Seller or Purchaser in connection with its performance as Exchange Escrow
Agent, except in the event of intentional wrongdoing or negligence. Exchange
Escrow Agent is authorized only to do those acts necessary and proper to effect
the purpose of this Agreement.
                           (x)  The Exchange Escrow Agent shall use the
Escrow Account, for payment of the deposit and all other payments due under the
Exchange Contract to purchase the Exchange Property, plus closing costs, and for
no other purpose.
                           (xi) If the payment for the Exchange Property
shall exceed the amount of the Escrow Account, Seller either shall: (i) deposit
an amount equal to such excess with Exchange Escrow Agent no later than the day
of the Exchange Property Closing; or (ii) cause or direct that the funds
necessary to effectuate the Exchange Property Closing be paid directly to
Exchange Seller at the Exchange Property Closing.
                           (xii)  At the Exchange Property Closing, the
following shall be deposited or caused to be deposited with Exchange Escrow
Agent: (i) a deed for the Exchange Property from Exchange Seller as grantor to
Seller, as grantee; and (ii) any other documents or agreements necessary or
incidental to the acquisition or conveyance of the Exchange Property.
                           (xiii)  When all documents and funds called for
herein have been deposited with Exchange Escrow Agent and when a title policy
can be issued on the Exchange Property to Seller,
<PAGE>

subject only to title exceptions approved by Seller, Exchange Escrow Agent shall
record the deed, disburse the funds and deliver all other documents to Seller.
All expenses, reimbursements and prorations in connection with the Exchange
Property shall be governed by the provisions of the Exchange Contract, except as
expressly set forth herein.
                           (xiv)  Purchaser makes no warranty with respect to
the Exchange Property and Seller assumes all responsibility for title to the
Exchange Property being good and marketable. Seller agrees to indemnify
Purchaser and hold Purchaser harmless from any damages, liability, costs,
expenses, claims, losses or demands (including reasonable attorneys' fees and
costs of litigation including those for enforcing this indemnity), arising out
of or in any way related to the acquisition of the Exchange Property. If the
Exchange Property is subject to any mortgage, deed of trust or lease, Purchaser
shall assume no liability or obligation with respect to said mortgage, deed of
trust or lease. Purchaser makes no representations as to the tax consequences of
any aspect of this transaction.
                           (xv) If the Exchange Property as may be designated
by Seller is not conveyed to Seller within the earlier of: (i) one hundred
eighty (180) days after Closing; or (ii) the due date (determined with regard to
extensions) of Seller's federal income tax return for the taxable year in which
the transfer of the Property occurs or if no Exchange Property is designated
within forty-five (45) days following Closing, then the Escrow Account
<PAGE>

shall be released to Seller, free of the escrow, and the obligations of
Purchaser and Exchange Escrow Agent shall end. Notwithstanding failure of the
Exchange Property to be conveyed to Seller as hereinabove set forth, the
transfer of the Property to Purchaser shall not be subject to recession or
revocation by Seller or Purchaser for any reason whatsoever.

                  (g) Seller shall give Purchaser at least sixty (60) days prior

         63. TITLE.
                  (a) Seller shall convey title to the Property and Purchaser
shall accept Marketable Title (as hereinafter defined), subject only to the
encumbrances set forth on Schedule "D" ("Permitted Encumbrances"). Marketable
Title shall mean that fee title to the Property is vested in Seller and shall be
insured as such by a title company selected by Purchaser (herein referred to as
the "Title Company") at standard rates; and that Purchaser shall not incur any
damage, cost or expense resulting from any encroachment or overlap affecting the
Property. Title Company shall certify that Seller has the right, authority and
power to
<PAGE>

enter into and to perform its obligations hereunder. The legal description in
the Binder (as hereinafter defined) and in the Deed (as hereinafter defined)
shall be in accordance with a current survey showing the completed Improvements
satisfactory to Title Company and Purchaser.
                  (b) Purchaser has received a title insurance binder (herein
referred to as the "Binder"), a copy of which has been delivered to Seller.
Prior to the expiration of the Due Diligence Period (as hereinafter defined),
Purchaser shall deliver to Seller's attorney notice of any objections to title
which are not Permitted Encumbrances. After the execution hereof, no further
liens, encumbrances, easements or restrictions shall be created or filed
("Subsequent Encumbrances") on or with respect to the Property. The Binder, at
the request of Purchaser, shall contain the following endorsements so that at
Closing, Title Company will issue an Owner's Policy of Title Insurance (American
Land Title Association Owner's Policy - 1992, or equivalent, in Purchaser's sole
judgment), in the full amount of the Purchase Price (the "Title Policy"):
                           (i)  a zoning endorsement certifying that the
Property is not subject to any ordinance, regulation or restriction which in any
way would prohibit or restrict the construction, maintenance and/or use of the
insured Property for its present use;
                           (ii) an endorsement insuring contiguity between or
among all of the tracts or parcels of land comprising the
<PAGE>

Property;
                           (iii) an endorsement deleting any coverage
exclusions with respect to creditor's rights; and
                           (iv)  an endorsement affirmatively insuring access
to public streets, highway and roadways.
         If the Binder discloses any exceptions, liens, encumbrances, defects or
objections other than the Permitted Encumbrances or if, after execution hereof,
a Subsequent Encumbrance shall be placed against the Property or if the Title
Company is unable to issue the endorsements (herein collectively called the
"Title Defect(s)"), then Purchaser shall have the right to: (i) require Seller
to use best efforts to cure any such Title Defects (except that Seller shall be
obligated to cure any Title Defects which can be removed solely by the payment
of a sum of money); (ii) attempt to cure any such Title Defect; (iii) accept
such title as Seller shall be able to convey and proceed to Closing without
reduction in the Purchase Price; (iv) cause a title report and title insurance
policy to be issued by another title company without such Title Defect; (v)
elect not to purchase the Property and declare this Agreement null and void,
whereupon Purchaser shall be entitled to the return of the Letter of Credit;
provided, however, if Seller gives notice to Purchaser within five (5) days
after Purchaser's election under this subparagraph (v), that Seller intends to
cure such Title Defects and thereafter cures such Title Defects in accordance
with the terms of this Agreement within thirty (30) days after receipt of notice
<PAGE>

from Purchaser of its election under this subparagraph (v), then Purchaser's
notice of termination shall be deemed negated and the transaction contemplated
by this Agreement shall proceed pursuant to the terms of this Agreement. The
right of Purchaser to terminate this Agreement may be exercised following the
exercise of its other rights hereunder.
                  (c) If at Closing there are liens or encumbrances against the
Property other than Permitted Encumbrances, Seller may use any portion of the
Purchase Price to satisfy same, provided Seller, at Closing, either shall: (1)
deliver to Purchaser instruments in recordable form sufficient to satisfy such
liens or encumbrances of record, together with the cost of recording or filing
said instruments; or (2) deposit with Title Company sufficient monies acceptable
to Title Company to insure obtaining and recording of such satisfactions and the
issuance of a Title Policy for the Property to Purchaser free and clear of any
such liens or encumbrances, but only to the extent that such liens or
encumbrances are in favor of and held by institutional lenders. The existence of
any such liens or encumbrances shall not be deemed objections or exceptions to
title if Seller shall comply with the foregoing requirements.
                  (d) If a search of title discloses judgments, bankruptcies or
other returns against other persons or entities having names the same as or
similar to that of Seller or any predecessor in title, Seller, on request, shall
deliver to Title Company, an affidavit showing that such judgments, bankruptcies
<PAGE>

or other returns are not against Seller or such predecessors in
interest of Seller.

                           (H)  At the time of Closing, all obligations of
Seller pursuant to the Leases with respect to performance of work or

                  (c) In the event that either party knows or learns that any of
the representations contained in this Agreement are false or no longer are true
and accurate, such party forthwith shall deliver notice of such fact to the
other party, and the other party shall proceed diligently to cure or remedy such

Purchaser. After Seller shall receive notice of a claim that may give rise to an
indemnity hereunder, Seller shall notify Purchaser; provided, however, the
failure to give any notice shall not relieve Purchaser from any liability
hereunder unless such failure impairs the right to defend such action. In the

have liability under the indemnity agreement contained in this Paragraph 7.(b),
the claim may, upon written agreement of Purchaser that it is obligated to
indemnify against the particular claim under the indemnity contained herein, be

Closing Date for any period from and after the Closing Date, the same shall be
held in trust and immediately paid to Purchaser.
                  (g) All rent payments received by Seller or Purchaser after
Closing shall be applied firstly against out-of-pocket costs of collection, then

amendments hereto, without any further writing, and the costs for enforcing this
Guaranty (collectively, the "Obligations").
                  (b) This is a guaranty of payment and performance and not of
collection. The obligations of Guarantors hereunder are independent of the
obligations of Seller, and a separate action or actions may be brought and

                  (c)  Guarantors agree that the obligations of
<PAGE>

Guarantors under this Paragraph 25 are primary, absolute and unconditional,
irrespective of the value, genuineness, validity, regularity or enforceability
of any of the Agreement or any instrument referred to herein, or any
substitution, release or exchange of any other guaranty of or security for the
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever (including, without
limitation, personal defenses of Seller) which might otherwise constitute a
legal or equitable discharge or defense of a surety, guarantor or co-obligor, it
being the intent of this Paragraph 25 that the obligations of Guarantors
hereunder shall be primary, absolute and unconditional under any and all
circumstances. Without limiting the generality of the foregoing, it is agreed
that the occurrence of any one or more the following shall not alter or impair
the liability of Guarantors hereunder:
                           (i)  at any time or from time to time, without
notice to or consent of Guarantors, the time for any performance of or
compliance with the Obligations shall be extended, or such performance or
compliance shall be waived;
                           (ii) any modification of or amendment to the
Agreement;
                           (iii)     the existence of any claim, set-off or
other right which Guarantors may have at any time against Purchaser, Seller or
any other person or entity, whether in connection herewith or with any unrelated
transaction;
<PAGE>

                           (iv) any of the acts required or contemplated in
any of the provisions of the Agreement or other instruments
referred herein shall be done or omitted;
                           (v)  the maturity of any of the Obligations shall
be accelerated or extended, or any of the Obligations shall be modified,
supplemented or amended in any respect or any right under the Agreement or other
instruments referred to herein shall be waived or extended or any other guaranty
of the Obligations or any security therefor shall be released or exchanged in
whole or in part or otherwise dealt with;
                           (vi) Purchaser releases or substitutes any one or
more of any Seller, endorses or guarantors of the Obligations;
                           (vii)     any of the Obligations shall be
determined to be void or voidable or shall be subordinated to the
claims of any person; or
                           (viii)    there shall be occur any insolvency,
bankruptcy, reorganization or dissolution of Seller or other
guarantor.
         With respect to their obligations hereunder, Guarantors hereby
expressly waive diligence, presentment, demand of payment, protest and all
notices whatsoever and any requirement that Purchaser exhaust any right, power
or remedy or proceed against any person under the Agreement or other instruments
referred to herein, or against any collateral or other person under any other
guaranty of, or security for, or obligation relating to, any of the Obligations.
<PAGE>

                  (d) The obligations of Guarantors under this Paragraph 25
shall be automatically reinstated if and to the extent that for any reason any
payment or performance by or on behalf of any persons in respect of the
Obligations is rescinded or must be otherwise restored by Purchaser or any other
holder or recipient of payment or performance of the Obligations, whether as a
result of any proceedings in bankruptcy or reorganization or otherwise, and
Guarantors agree that they will pay to Purchaser on demand all reasonable
out-of-pocket costs and expenses (including, without limitation, fees of
counsel) incurred by Purchaser in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.
                  (e) Without limiting the generality of the provisions of this
Paragraph 25, Guarantors hereby specifically waive: (a) promptness, diligence,
notice of acceptance and any other notice with respect to the Obligations; (b)
any requirement that Purchaser protect, secure or insure any lien or any
property subject thereto or exhaust any right or take any action against Seller
or any collateral or undertake any marshalling of assets; (c) the right to
direct the order of enforcement or remedies, (d) any defense arising by reason
of any claim or defense based upon an election of remedies by Purchaser which in
any manner impairs, reduces, releases or otherwise adversely affects its
subrogating,
<PAGE>

contribution or reimbursement rights or other rights to proceed against Sellers
or any collateral; (e) any duty on the part of Purchaser to disclose to
Guarantors any matter, fact or thing relating to the business, operation or
condition of the Property or Seller and its assets now known or hereafter known
by Purchaser; and (f) all presentments, demands for performance, notices of
nonperformance, protests, notices of protest, notices of dishonor, and notices
of acceptance of the guaranty provided for in this Paragraph 25 and the
existence, creation or incurrence of new or additional indebtedness.
         84. ROLLBACK TAXES. Any "rollback taxes" assessed or to be assessed
against the Premises pursuant to the Farmland Assessment Act of 1964, N.J.S.A.
54:4-23.1, et seq., shall be paid by Seller. If rollback taxes will be due with
respect to the Premises but are not assessed at the Closing Date, a good-faith
estimate of the amount of same shall be obtained by the parties from the tax
assessor of the Township of Moorestown, at least twenty-four (24) hours prior to
Closing, and Seller shall pay one hundred twenty-five (125%) percent of the
amount of said estimate from the proceeds at Closing into escrow to be held by
the Title Company until such time as the rollback tax assessment against the
Premises is made. Upon Title Company's receipt of notice from Purchaser that
said rollback taxes have been assessed against the Premises, Title Company
shall, within three (3) business days thereof, pay said taxes to the Township of
Moorestown. In the event the amount of the monies being held in
<PAGE>

escrow by Title Company are not sufficient to cover payment of said rollback
taxes, then Seller shall promptly pay to Purchaser any additional monies that
are due and payable by Seller in accordance with the terms and provisions of
this Paragraph; and in the event the amount of the escrow monies are in excess
of the amount of said rollback taxes, then Title Company shall disburse the
remaining balance of the escrow funds to Seller after the amount of the escrow
monies due to Purchaser have been disbursed to the Township of Moorestown, in
accordance with the terms and provisions of the immediately proceeding sentence.
Seller shall indemnify and hold Purchaser harmless from and against all costs
and expenses, including reasonable attorneys fees, incurred by Purchaser in
connection with Seller's failure to perform Seller's obligations under this
Paragraph 26.
         85. SELLER'S RIGHT TO EXCHANGE PROPERTY.
                  (a) (i) Seller shall have the right, exercisable at least five
(5) days prior to Closing, to elect to exchange the Property for other property
of like kind ("Exchange Property") pursuant to Section 1031 of the Internal
Revenue Code of 1986, as amended.
                           (ii) If Seller elects to effect any exchange, it
shall notify Purchaser as to all details thereof, and Purchaser shall execute a
contract to purchase the Exchange Property in a form satisfactory to Seller
(hereinafter called the "Exchange Contract"), and immediately thereafter shall
assign all of its right, title and interest in and to the Exchange Contract to
the
<PAGE>

Exchange Escrow Agent, as hereinafter defined. The funds required to pay the
deposit under the Exchange Contract shall be provided to Purchaser by Seller or
Exchange Escrow Agent. The Exchange Contract shall provide for the right of
assignment by Purchaser to Exchange Escrow Agent and/or Seller without recourse,
and that the seller of the Exchange Property shall look only to the deposit
monies thereunder as liquidated damages, there being no liability on the part of
Purchaser to said seller. Purchaser shall not be obligated to execute an
Exchange Contract which would require Purchaser to be personally liable on any
indebtedness or to incur any cost or expense which would increase Purchaser's
liability beyond that liability incurred by Purchaser hereunder.
                           (iii)  In no event, however, shall the closing of
title to the Property be delayed due to the inability of Seller to select an
Exchange Property or close title thereto.
                  (b) (i) If Seller shall elect to exchange the Property
pursuant to this Paragraph, whether or not an Exchange Property has been
designated, as herein set forth, the Purchase Price, exclusive of the
satisfaction of liens, payment of closing costs and other permitted expenses,
shall be deposited with the Exchange Escrow Agent ("Escrow Account"), subject to
the Exchange Escrow Agent executing an agreement reasonably satisfactory to
Purchaser whereby Exchange Escrow Agent agrees to be bound by the terms and
conditions of this Paragraph 27, and shall not be paid to Seller at Closing. The
Escrow Account shall be held by
<PAGE>

Exchange Escrow Agent in an interest bearing account, pursuant to the terms
hereof. The interest earned upon the Escrow Account while being held by Exchange
Escrow Agent shall be added to the Escrow Account and shall be paid to Seller at
the closing of the Exchange Property.
                           (ii) Purchaser appoints its title insurance
company or such other title insurance company or other entity as Purchaser
reasonably may designate, its agent, in order to effectuate the Exchange (the
"Exchange Escrow Agent"). Purchaser and Seller shall cooperate with each other
and Exchange Escrow Agent and promptly shall sign and deliver to Exchange Escrow
Agent all documents reasonably deemed necessary by Seller in order to qualify
this transaction pursuant to Internal Revenue Code Section 1031.
                           (iii)  Seller shall pay all fees relating to the
Escrow Account, and all reasonable attorneys' fees and expenses of Purchaser, if
any, relating to the exchange transaction and in no event shall Purchaser be
required to assume any liability thereunder.
                           (iv) During the period that the Escrow Account is
in existence, Seller shall not have any control, directly or indirectly, over
the funds placed in the Escrow Account, except as may be expressly provided
herein.
                           (v)  If, at the time of Closing, Seller shall not
have designated the Exchange Property, then if within forty-five (45) days
following Closing, Seller shall deliver to Purchaser
<PAGE>

and to Exchange Escrow Agent a designation of an Exchange Property which Seller
desires to acquire by way of exchange for the Property transferred to Purchaser
at Closing ("Designation"), the parties shall proceed as provided for herein. If
there is no timely Designation, then Exchange Escrow Agent, on the forty-sixth
(46th) day after Closing (or, if such day is a Saturday, Sunday or legal
holiday, on the first business day thereafter) shall disburse to Seller the
Escrow Account and all interest earned thereon shall be paid to Purchaser.
                           (vi) Any Designation of an Exchange Property shall
include an Exchange Contract, or thereafter Seller shall provide Purchaser with
an Exchange Contract, which Exchange Contract comply with the terms set forth in
Subparagraph 27.(a). The parties acknowledge that there may be multiple Exchange
Properties and that multiple Designations may be delivered, provided that each
meets the conditions set forth herein and the requirements of the Internal
Revenue Code Section 1031 and regulations thereunder.
                           (vii)  Upon receipt by Purchaser of an Exchange
Contract, it shall execute and deliver the Exchange Contract to the seller of
the Exchange Property ("Exchange Seller"), Seller and Exchange Escrow Agent.
Thereafter, Purchaser shall assign its interest in the Exchange Contract to
Exchange Escrow Agent, it being agreed that Purchaser shall not take title to
any Exchange Property.
                           (viii)  Upon Purchaser executing any Exchange
<PAGE>

Contract, and in accordance therewith, Exchange Escrow Agent shall pay from the
Escrow Account to Exchange Seller, or such other party as is provided for in the
Exchange Contract, the amount of the deposit and all other monies required under
the Exchange Contract or otherwise related to the transaction.
                           (ix) Exchange Escrow Agent shall not be liable to
either Seller or Purchaser in connection with its performance as Exchange Escrow
Agent, except in the event of intentional wrongdoing or negligence. Exchange
Escrow Agent is authorized only to do those acts necessary and proper to effect
the purpose of this Agreement.
                           (x)  The Exchange Escrow Agent shall use the
Escrow Account, for payment of the deposit and all other payments due under the
Exchange Contract to purchase the Exchange Property, plus closing costs, and for
no other purpose.
                           (xi) If the payment for the Exchange Property
shall exceed the amount of the Escrow Account, Seller either shall: (i) deposit
an amount equal to such excess with Exchange Escrow Agent no later than the day
of the Exchange Property Closing; or (ii) cause or direct that the funds
necessary to effectuate the Exchange Property Closing be paid directly to
Exchange Seller at the Exchange Property Closing.
                           (xii)  At the Exchange Property Closing, the
following shall be deposited or caused to be deposited with
Exchange Escrow Agent: (i) a deed for the Exchange Property from
Exchange Seller as grantor to Seller, as grantee; and (ii) any
<PAGE>

other documents or agreements necessary or incidental to the
acquisition or conveyance of the Exchange Property.
                           (xiii)  When all documents and funds called for
herein have been deposited with Exchange Escrow Agent and when a title policy
can be issued on the Exchange Property to Seller, subject only to title
exceptions approved by Seller, Exchange Escrow Agent shall record the deed,
disburse the funds and deliver all other documents to Seller. All expenses,
reimbursements and prorations in connection with the Exchange Property shall be
governed by the provisions of the Exchange Contract, except as expressly set
forth herein.
                           (xiv)  Purchaser makes no warranty with respect to
the Exchange Property and Seller assumes all responsibility for title to the
Exchange Property being good and marketable. Seller agrees to indemnify
Purchaser and hold Purchaser harmless from any damages, liability, costs,
expenses, claims, losses or demands (including reasonable attorneys' fees and
costs of litigation including those for enforcing this indemnity), arising out
of or in any way related to the acquisition of the Exchange Property. If the
Exchange Property is subject to any mortgage, deed of trust or lease, Purchaser
shall assume no liability or obligation with respect to said mortgage, deed of
trust or lease. Purchaser makes no representations as to the tax consequences of
any aspect of this transaction.
                           (xv) If the Exchange Property as may be designated
by Seller is not conveyed to Seller within the earlier of: (i)
<PAGE>

one hundred eighty (180) days after Closing; or (ii) the due date (determined
with regard to extensions) of Seller's federal income tax return for the taxable
year in which the transfer of the Property occurs or if no Exchange Property is
designated within forty-five (45) days following Closing, then the Escrow
Account shall be released to Seller, free of the escrow, and the obligations of
Purchaser and Exchange Escrow Agent shall end. Notwithstanding failure of the
Exchange Property to be conveyed to Seller as hereinabove set forth, the
transfer of the Property to Purchaser shall not be subject to recession or
revocation by Seller or Purchaser for any reason whatsoever.
                                      [REST OF PAGE INTENTIONALLY LEFT BLANK]

         IN WITNESS WHEREOF, the parties hereto have set their hands and seals
or caused these presents to be signed and sealed by duly authorized persons the
day and year first above written.

                                                    Background

         Lender is the holder of a Mortgage Note dated September 1, 1993

                  (d) The Mortgage is hereby modified to insert the following at
the end of Section 7:

         "Notwithstanding the foregoing, (i) transfers of interests in Mack-Cali

         Mortgagee (provided that no such transfers shall limit in any way
         Mortgagor's obligations hereunder), and (ii) with advance written
         notice to Mortgagee (but without requiring Mortgagee's consent), the
         Mortgaged Property may be conveyed to an affiliate of Mortgagor or
         following a merger or consolidation of Mortgagor (provided that no such
         transfers shall limit in any way Mortgagor's obligations hereunder)."

                  (e) The Mortgage is hereby modified to delete the phrase "and
certified by John McGarvey" in Section 12.

                  (f) The Mortgage is hereby modified to add the phrase "except

         2. Assumption of Loan Documents; Representations and Warranties.

                  (a) MCR hereby assumes the obligations of the McGarveys under

Inc. as policy issuing agent for First American Title

except as specifically modified by this Agreement, all of the terms and
conditions of the Note, the Mortgage and the other Loan Documents shall be
unmodified and remain in full force and effect and are hereby ratified and
confirmed by MCR. MCR acknowledges and agrees that it has no defense, set-off,
recoupment or claim against Lender of any kind whatsoever as of the date hereof.
Lender acknowledges that all principal, accrued interest and other charges for
the Loan have been paid through the installment payment due on January 1, 1998.
Lender has not declared an Event of Default under the Note, the Mortgage or any
of the other Loan Documents and has no knowledge of any state of facts which,
but for the passage of time or the giving of notice, would constitute an Event
of Default under the Note, the Mortgage or the other Loan Documents.

         4. No Novation. The parties to this Agreement acknowledge and confirm
that this Agreement shall not be construed as a novation of the Note, the
Mortgage or the other Loan Documents, and shall not prejudice any present or
future rights, remedies, benefits or powers belonging to or accruing to Lender
under the terms of the Note, the Mortgage or the other Loan Documents. It is the
intent of the parties hereto that this Agreement shall in no way adversely
affect or impair the lien priority of the Mortgage. In the event this Agreement
or any part hereof, or any instrument executed in connection herewith, shall be
construed or shall operate to affect the lien priority of the Mortgage, then to
the extent such instrument creates a charge upon the Mortgaged Property, and to
the extent third parties acquiring an interest or lien upon the Mortgaged
Property between the time the Mortgage was recorded and the time this Agreement
is executed are prejudiced thereby, this Agreement shall be void and of no
further force or effect. Notwithstanding the foregoing, the parties hereto, as
between themselves, shall be bound by all the terms and conditions of this
Agreement until the Loan and all interest thereon has been paid in full.

         5. No Further Commitment. Nothing in this Agreement shall be construed
to commit Lender to any further modification or amendments of the Note, the
Mortgage or the other Loan Documents, nor as a waiver by Lender of any rights or
remedies to which Lender may be entitled under the Loan Documents.

         6. Releases.

                  (a) MCR, its partners, employees and agents, for themselves,

             NOTE AND MORTGAGE MODIFICATION AND ASSUMPTION AGREEMENT

         THIS NOTE AND MORTGAGE MODIFICATION AND ASSUMPTION AGREEMENT
("Agreement") is made this 30th day of January, 1998, by and between MACK-CALI
REALTY, L.P., a Delaware limited partnership, having a mailing address of 11
Commerce Drive, Cranford, New Jersey 07016 (hereinafter called "BORROWER") and
FIRST UNION NATIONAL BANK, a national banking association organized and existing
under the laws of the United States of America, successor by merger to FIRST
FIDELITY BANK, NATIONAL ASSOCIATION, with offices at One First Union Center,
DC-6, Charlotte, North Carolina 28288 (hereinafter called "BANK"); and BROMLEY
COMMON ASSOCIATES, a New Jersey general partnership, 201 Commerce Drive, having
a mailing address of Moorestown, New Jersey 08057 (the "Original Borrower",
hereinafter "Bromley")

                                                    BACKGROUND

         On or about September 15, 1995, Bromley borrowed from Bank the
principal sum of Six Million Seven Hundred Thousand Dollars ($6,700,000.00) (the
"Loan") and made, executed and delivered to Bank its Promissory Note (the
"Note") payable with interest per annum at the fixed rate of seven and
one-quarter percent (7.25%) in consecutive monthly payments of principal and
interest, based upon a hypothetical fifteen (15) year term, with all unpaid
principal and interest accrued thereon due and payable in full on October 31,
2000. Bromley was afforded the option to extend the maturity date for an
additional term of sixty (60) months.

         As collateral security for the obligations of Bromley to Bank, Bromley
on September 15, 1995, executed and delivered to Bank, together with other
documents (the "Loan Documents") (including a certain loan agreement dated
September 15, 1995, the "Loan Agreement"), a Mortgage and Security Agreement
(the "Mortgage") on the premises owned by Bromley and located in the Township of
Burlington, County of Burlington, State of New Jersey, known and designated as
Block 120.03, Lots 1 and 2 on the official tax map, commonly known as #3 and #5
Terri Lane, Bromley Corporate Center (the "Mortgaged Premises"), said property
being more fully described in Exhibit "A" attached hereto and made a part
hereof, said Mortgage having been recorded on September 25, 1995 in the Office
of the Clerk of Burlington County in Book 6091 of Mortgages Page 232.

         Bromley has requested that the Bank permit the Borrower to assume the
Loan to Bromley and modify the Loan. Borrower has agreed to repay to Bank all
amounts which are due under the terms of the Note, as modified hereby, and Bank
has agreed to modify the Note and Mortgage and to memorialize same, hence this
Agreement.

party thereto. Bromley, Borrower and Bank acknowledge that the amount of the

                           Premises or any part thereof consisting more than
                           fifty percent (50%) of the leased area of the

EXHIBIT NO. 10.135

                   LOAN MODIFICATION AND ASSUMPTION AGREEMENT


         This Loan Modification and Assumption Agreement is made this 30th day
of January, 1998 by and among MOORESTOWN WEST PARTNERSHIP, a New Jersey general
partnership ("Partnership"), MACK-CALI REALTY, L.P., a Delaware limited
partnership ("MCR"), and SUN LIFE ASSURANCE COMPANY OF CANADA, a Canadian
corporation ("Lender").

                                   Background

         Lender is the holder of a Mortgage Note dated May 18, 1994 ("Note") in
the original principal amount of $2,950,000 ("Loan") made by the Partnership.
The Note is secured by, inter alia, a Mortgage and Security Agreement dated May
18, 1994 and recorded in the Office of the County Clerk of Burlington County
Records on July 14, 1994 in Mortgage Book 5632 page 001 ("Mortgage"),
encumbering two certain parcels of real property and the improvements thereon
located at 101 Executive Drive and 225 Executive Drive, Moorestown, Burlington
County, New Jersey, as more particularly described on Exhibit A ("Mortgaged
Property"), and by an Assignment of Leases and Agreement dated May 18, 1994 and
recorded in the Office of the County Clerk of Burlington County Records on July
14, 1994 in Deed Book 4769 page 088 ("Assignment of Leases"), and by an
Unconditional Guaranty and Suretyship Agreement dated May 18, 1994 ("Guaranty")
executed by John S. McGarvey, Joanne H. McGarvey and William G. Price, Jr.
(collectively, "Guarantors") (the Note, the Mortgage, the Assignment of Leases
and the other documents listed on Exhibit B attached hereto which were executed
by Partnership and delivered to Lender in connection with the Loan are
hereinafter referred to collectively as the "Loan Documents").

         The Mortgaged Property is being acquired by MCR from the Partnership on
the date hereof. Lender and MCR have now agreed to modify certain provisions of
the Loan Documents and that MCR will assume the obligations of the Partnership
under the Loan Documents as modified hereby.

         Now, Therefore, in consideration of the mutual covenants and
undertakings herein contained, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, and intending to
be legally bound hereby, the parties hereto covenant and agree as follows:

         1. Modification of Loan Documents.

                  (a) The Note is hereby modified to insert the following
paragraph as a new Section 20:

         "20. Notwithstanding anything to the contrary herein contained, the
         liability of Maker hereunder shall be limited to and enforceable only
         out of the Mortgaged Property and the rents, issues and profits
         therefrom, and the lien of any judgment shall be restricted thereto and
         shall not extend to Maker, Holder waiving any right Holder may have to
         claim a
<PAGE>

         deficiency judgment against Maker; provided, however, that Maker shall
         not be exonerated or exculpated for any deficiency, loss or damage
         suffered by Holder as a result of any security deposits received or
         held by Maker, any rent received or held by Maker after an Event of
         Default, or any rent prepaid more than one month in advance; or from
         failure by Maker to properly account to Holder as mortgagee for any
         proceeds of insurance or condemnation proceeds as required by the
         Mortgage; or from repairs required by the Mortgaged Property following
         a casualty for which insurance proceeds are not available due to a
         violation of Section 10 of the Mortgage; or from fraud, material
         misrepresentation or bad faith by Maker; or from waste of the Mortgaged
         Property; or from delinquent taxes or assessments; or from Maker's
         interference with Holder's rights under the Assignment of Leases after
         an Event of Default; or from Maker's failure, following an Event of
         Default, to apply proceeds of rents and other income of the Mortgaged
         Property toward the cost of claims, insurance premiums, debt service
         and other indebtedness to the extent that the Mortgage, the Assignment
         of Leases or any of the other Loan Documents require such rents and
         income to be so applied; or the presence on the Mortgaged Property of
         any hazardous substances, hazardous waste, residual waste, solid waste
         or any other substance identified or described in Section 4(b) of the
         Mortgage, any violation by Maker or the Mortgaged Property of any
         environmental law, ordinance or regulation, or Maker's violation of, or
         failure to perform its obligations under, Section 4 or Section 20 of
         the Mortgage; or any noncompliance of the Mortgaged Property with the
         Americans with Disabilities Act. Notwithstanding the foregoing, Maker's
         obligations hereunder shall be limited as set forth in Section 37 of
         the Mortgage. Nothing in this paragraph, however, shall limit Holder's
         right against any tenants under leases assigned to Holder as additional
         security, or against any other collateral securing Maker's obligations
         hereunder, now or hereafter mortgaged, pledged or assigned by Maker or
         anyone else to Holder."

                  (b) The Note is hereby modified to delete the phrase "of
partnership interests" in the first sentence of Section 6 and to delete the last
sentence of Section 6.

                  (c) The Mortgage is hereby modified to insert the following
paragraph as a new Section 37:

         "37. LIMITATION OF LIABILITY. (i) Notwithstanding anything to the
         contrary herein contained, the liability of Mortgagor hereunder shall
         be limited to and enforceable only out of the Mortgaged Property and
         the rents, issues and profits therefrom, and the lien of any judgment
         shall be restricted thereto and shall not extend to Mortgagor,
         Mortgagee waiving any right Mortgagee may have to claim a deficiency
         judgment against Mortgagor; provided, however, that Mortgagor shall not
         be exonerated or exculpated for any deficiency, loss or damage suffered
         by Mortgagee as a result of any security deposits received or held by
         Mortgagor, any rent received or held by Mortgagor after an Event of
         Default, or any rent prepaid more than one month in advance; or from
         failure by Mortgagor to properly account to Mortgagee as mortgagee for
         any proceeds of insurance or condemnation proceeds as required by the
         Mortgage; or from repairs required by the Mortgaged Property following
         a casualty for which insurance proceeds are not available due to a
         violation of Section 10 of the Mortgage; or from fraud, material
         misrepresentation or bad faith by Mortgagor; or from waste of the
         Mortgaged Property; or
<PAGE>

         from delinquent taxes or assessments; or from Mortgagor's interference
         with Mortgagee's rights under the Assignment of Leases after an Event
         of Default; or from Mortgagor's failure, following an Event of Default,
         to apply proceeds of rents and other income of the Mortgaged Property
         toward the cost of claims, insurance premiums, debt service and other
         indebtedness to the extent that the Mortgage, the Assignment of Leases
         or any of the other Loan Documents require such rents and income to be
         so applied; or the presence on the Mortgaged Property of any hazardous
         substances, hazardous waste, residual waste, solid waste or any other
         substance identified or described in Section 4(b) of the Mortgage, any
         violation by Maker or the Mortgaged Property of any environmental law,
         ordinance or regulation, or Maker's violation of, or failure to perform
         its obligations under, Section 4 or Section 20 of the Mortgage; or any
         noncompliance of the Mortgaged Property with the Americans with
         Disabilities Act. Nothing in this paragraph, however, shall limit
         Mortgagee's right against any tenants under leases assigned to
         Mortgagee as additional security, or against any other collateral
         securing Mortgagor's obligations hereunder, now or hereafter mortgaged,
         pledged or assigned by Mortgagor or anyone else to Mortgagee.
                  (ii) Notwithstanding the provisions of Section 37(i) above,
         Mortgagor's recourse liability under Section 37 (i) shall not exceed
         $2,410,000.00 (as to 101 Executive Drive) and $2,695,000.00 (as to 225
         Executive Drive) (collectively, "Liability Cap")."

                  (d) The Mortgage is hereby modified to delete the last
sentence of Section 7, and to insert in place thereof the following:

         "Notwithstanding the foregoing, (i) transfers of interests in Mack-Cali
         Realty, L.P. and its general partner shall not require the consent of
         Mortgagee (provided that no such transfers shall limit in any way
         Mortgagor's obligations hereunder), and (ii) with advance written
         notice to Mortgagee (but without requiring Mortgagee's consent), the
         Mortgaged Property may be conveyed to an affiliate of Mortgagor or
         following a merger or consolidation of Mortgagor (provided that no such
         transfers shall limit in any way Mortgagor's obligations hereunder)."

                  (e) The Mortgage is hereby modified to delete the phrase
"certified by John McGarvey" in Section 12.

                  (f) The Mortgage is hereby modified to add the phrase "except
as expressly permitted by the Assignment of Leases" at the end of Section

                  (h) The Assignment of Leases is hereby modified to add the
following at the end of Section 1(a):

         "Notwithstanding the foregoing, no consent from Mortgagee shall be
         required for (i) Leases for space in 101 Executive Drive if such Leases
         require a net rental of at least $7.00 per square foot, and (ii) Leases
         for space in 225 Executive Drive if such Leases require a net rental of
         at least $4.75 per square foot."
<PAGE>

                  (i) The Loan Documents are all hereby modified to delete any
reference to the Guaranty.

         2. Assumption of Loan Documents; Representations and Warranties.

                  (a) MCR hereby assumes the obligations of the Partnership
under the Note and the Mortgage (as modified herein) and the other Loan
Documents as if each and every Loan Document had been originally executed by
MCR, provided that MCR is not assuming any obligations under the Guaranty. MCR
shall fully comply with each and every covenant and condition of the Loan
Documents and shall be fully bound thereby.

                  (b) Lender hereby approves the transfer of the Mortgaged
Property by the Partnership to MCR.

                  (c) MCR acknowledges and agrees that the unpaid principal
balance of the Note as of the date hereof is $2,575,703.93. MCR represents and
warrants to Lender that MCR presently possesses an unencumbered fee simple title
to the Mortgaged Property, except for those title objections not removed from
Title Commitments No. TS-11347 and TS-11349 issued to Lender by Title Services
of New Jersey, Inc. as policy issuing agent for First American Title Insurance
Company, and that the Mortgage is a valid and enforceable first lien on the
Mortgaged Property, subject only to the aforesaid title objections.

                  (d) MCR represents and warrants to Lender as follows: (i) MCR
is a limited partnership duly formed and validly existing in the State of
Delaware; (ii) MCR has supplied Lender with true, correct and complete copies of
MCR's Limited Partnership Agreement and Limited Partnership Certificate, and all
amendments thereto, none of which has been further amended, modified or revised,
together with a current Good Standing Certificate from the State of Delaware;
and (iii) MCR has full power and authority to engage in business and own
property in the State of New Jersey and to enter into and undertake and perform
its obligations under the Note, the Mortgage and the other Loan Documents.

         3. Confirmation of Loan Documents. MCR covenants and confirms that,
except as specifically modified by this Agreement, all of the terms and
conditions of the Note, the Mortgage and the other Loan Documents shall be
unmodified and remain in full force and effect and are hereby ratified and
confirmed by MCR. MCR acknowledges and agrees that it has no defense, set-off,
recoupment or claim against Lender of any kind whatsoever as of the date hereof.
Lender acknowledges that all principal, accrued interest and other charges for
the Loan have been paid through the installment payment due on January 1, 1998.
Lender has not declared an Event of Default under the Note, the Mortgage or any
of the other Loan Documents and has no knowledge of any state of facts which,
but for the passage of time or the giving of notice, would constitute an Event
of Default under the Note, the Mortgage or the other Loan Documents.

         4. No Novation. The parties to this Agreement acknowledge and confirm
that this Agreement shall not be construed as a novation of the Note, the
Mortgage or the other Loan Documents, and shall not prejudice any present or
future rights, remedies, benefits or powers belonging to or accruing to Lender
under the terms of the Note, the Mortgage or the other Loan Documents. It is the
intent of the parties hereto that this Agreement shall in no way adversely
<PAGE>

affect or impair the lien priority of the Mortgage. In the event this Agreement
or any part hereof, or any instrument executed in connection herewith, shall be
construed or shall operate to affect the lien priority of the Mortgage, then to
the extent such instrument creates a charge upon the Mortgaged Property, and to
the extent third parties acquiring an interest or lien upon the Mortgaged
Property between the time the Mortgage was recorded and the time this Agreement
is executed are prejudiced thereby, this Agreement shall be void and of no
further force or effect. Notwithstanding the foregoing, the parties hereto, as
between themselves, shall be bound by all the terms and conditions of this
Agreement until the Loan and all interest thereon has been paid in full.

         5. No Further Commitment. Nothing in this Agreement shall be construed
to commit Lender to any further modification or amendments of the Note, the
Mortgage or the other Loan Documents, nor as a waiver by Lender of any rights or
remedies to which Lender may be entitled under the Loan Documents.

         6. Releases.

                  (a) MCR, its partners, employees and agents, for themselves,
their respective heirs, personal representatives, successors and assigns, hereby
release Lender, its shareholders, officers, directors, employees, agents and
attorneys and each of their respective heirs, personal representatives,
successors and assigns and affiliates, of and from any and all actions, causes
of action, proceedings, claims, demands, damages, costs, liabilities, losses,
agreements and obligations as of the date hereof, of any nature whatsoever,
whether contingent or matured, known or unknown, at law or in equity arising out
of, or in any way related to, the Loan, the Note, the Mortgage, the other Loan
Documents or the Mortgaged Property. MCR and its partners acknowledge and agree
that Lender is relying on the foregoing representations and covenants as a
material inducement to Lender to execute this Agreement.

                  (b) Lender, its shareholders, officers, directors, employees,
agents and attorneys and each of their respective heirs, personal
representatives, successors, assigns and affiliates, hereby release Partnership,
Guarantors, and their respective partners, employees, agents and attorneys and
each of their respective heirs, personal representatives, successors and
assigns, of and from any and all actions, causes of action, proceedings, claims,
demands, damages, costs, liabilities, losses, agreements and obligations, of any
nature whatsoever, whether contingent or material, known or unknown, at law or
in equity arising from any act, thing, omission or failure to act occurring
after the date hereof and arising out of, or in any way related to, the Loan,
the Mortgage, the Guaranty, the other Loan Documents or the Mortgaged Property,
including, without limitation, any failure of MCR to perform any of its
obligation under the Loan Documents. Lender acknowledges and agrees that
Partnership and Guarantors relied on the foregoing representations and covenants
as a material inducement to Partnership and Guarantors to execute this
Assumption Agreement.

         7. Notices. Section 25 of the Mortgage is hereby amended to provide

EXHIBIT NO. 10.136

                         AGREEMENT OF PURCHASE AND SALE


         THIS AGREEMENT, made as of the 2nd day of February, 1998 (the 
"Effective Date"), by and between BREL ASSOCIATES XIV, L.P., a New York limited
partnership, having an office at c/o Banque Nationale de Paris, 499 Park Avenue,
New York, New York 10022 (hereinafter referred to as "Seller"), and MACK-CALI
REALTY, L.P., 11 Commerce Drive, Cranford, New Jersey 07016 (hereinafter
referred to as "Purchaser").

                                               W I T N E S S E T H :

         WHEREAS, Seller is the owner of certain land(s), building(s) and
improvements (hereinafter collectively referred to as the "Property") situated
in the Borough of Fort Lee, County of Bergen, New Jersey, being commonly known
as 2115 Linwood Avenue, as more particularly described in Exhibit "A" annexed
hereto and made a part hereof; and

         WHEREAS, Seller desires to sell the Property and Purchaser desires to
purchase the Property on the terms and conditions hereinafter set forth.

         NOW, THEREFORE, in consideration of the mutual promises herein made, it
is agreed as follows:

         1. SALE AND PURCHASE. Seller agrees to sell and Purchaser agrees to
purchase the Property, including any and all easements, rights of way,
privileges, appurtenances and rights belonging to or inuring to the benefit of
said Property and any fixtures and personal property presently located at the
Property used in connection with the current operation of the Property, for the
Purchase Price (as hereinafter defined) and upon the terms and conditions
hereinafter provided. Seller reserves the right to remove from the Property
prior to the Closing (hereinafter defined) all wall partitions not installed in
the Property and all furniture and any other personal property located at the
Property not belonging to any tenants or occupants thereof.

         2. PURCHASE PRICE. The purchase price of the Property shall be
$5,000,000 Dollars (the "Purchase Price") payable by Purchaser as follows:

                  A. Upon execution and delivery of this Agreement, by
depositing with Wolff & Samson, P.A., Seller's Attorney (the "Escrow Agent"), a
sum equal to $500,000 Dollars by a good, unendorsed certified or official bank
check drawn on an account of Purchaser, subject to collection, payable to the
order of the Escrow Agent or, at Purchaser's election, by a bank wire transfer
of immediately available funds to an account or accounts designated by Escrow
Agent (the "Deposit"), which Deposit shall be maintained by Escrow Agent
pursuant to the provisions of Paragraph 29 of this Agreement.
<PAGE>

                  B. (i) At the closing of title, by paying to Seller the
balance of the Purchase Price by a wire transfer of immediately available funds
of Purchaser at a federal or state chartered bank or reputable, domestic lending
institution, subject to the adjustments and prorations described in Paragraph 16
of this Agreement.

                           (ii) If Purchaser shall fail to deliver the Deposit
in accordance with (A) above, or if Escrow Agent shall be unable immediately to
collect on such Deposit, such failure or inability shall constitute a default by
Purchaser, and this Agreement shall terminate and neither party shall have any
further obligation or liability to the other except as may otherwise be provided
for herein.

         3. CLOSING DOCUMENTS.

                  A. At the Closing, Seller shall execute and deliver to
Purchaser (i) a Bargain and Sale deed; (ii) an affidavit of title, the form and
substance of which shall be subject to the reasonable approval of Purchaser's
title insurance company; (iii) an assignment and assumption of Seller's interest
in the property management agreement or service contracts referred to in
Paragraph 8 hereof ("Assignment and Assumption of Contracts") in form
satisfactory to the parties; (iv) an affidavit by Seller that Seller is not a
"foreign person" within the meaning of Section 1445 of the United States
Internal Revenue Code of 1986, as amended, and the regulations issued
thereunder; (v) a letter of non-applicability from the New Jersey Department of
Environmental Protection to the effect that the Property is exempt from the
application of the Industrial Site Recovery Act, N.J.S.A. 13:1k-6 et seq.; and
(vi) such documents and/or instruments as may be reasonably required by
Purchaser's attorney or Purchaser's title insurance company to effectuate the
within transaction. The deed and any other documents which are intended to be
recorded shall be executed and acknowledged in a manner property for
recordation.

                  B. At the Closing, the Purchaser shall execute and deliver to
Seller (i) the balance of the Purchase Price; (ii) the Assignment and Assumption
of Contracts; and (iii) such documents and/or instruments as may reasonably be
required by Seller's attorney or Purchaser's title insurance company to
effectuate the within transaction.

         4. TITLE.

                  A. Purchaser, at its expense, shall obtain a title insurance
binder from a title insurance company doing business in the State of New Jersey
insuring marketable title (as hereinafter defined) to the Property. For the
purposes of this Agreement, "marketable title" shall be deemed to be such title
as any title insurance company doing business in the State of New Jersey shall
insure at standard rates and subject only to the usual printed exceptions and to
the Permitted Encumbrances set forth on Exhibit "B" annexed hereto (the
"Permitted Encumbrances"). Purchaser shall, by no later than ten (10) days after
the Effective Date, forward to Seller a copy of its title insurance binder and
specify in writing any alleged defects
<PAGE>

set forth in said binder ("Title Obligations"), failing which Purchaser shall be
deemed to have waived all Title Objections, TIME BEING OF THE ESSENCE as to
Purchaser's obligation to so notify Seller. Within two (2) business days
following Seller's receipt of said binder and notice of any Title Objections,
Seller shall have the right (without being obligated or required to commence
litigation or to incur any expenditure of monies), (i) to agree to cause any
Title Objection to be removed as a title exception prior to Closing, (ii) to
cause another title company to insure marketable title in accordance herewith;
or (iii) to take no action with respect to any Title Objections. If Seller
causes marketable title to be insured for the Property, Purchaser shall be
required to complete the purchase of the Property as herein provided. Seller
may, if it so elects, postpone the Closing for a period not to exceed sixty (60)
calendar days in order to cure a Title Obligation. If Seller is unable or
unwilling to cause marketable title to be insured for the Property, then
Purchaser shall have the right, at its sole option, either to (i) waive the
Title Objections and accept such title as Seller is able to convey without any
diminution in the Purchase Price, or (ii) terminate this Agreement.

                  B. Purchaser shall make its election to accept such title as
Seller shall be able to convey or to terminate this Agreement by no later than
the end of the Due Diligence Period. If Purchaser shall fail to so notify
Seller, then Purchaser shall be deemed to have elected to waive the Title
Objections and accept title without any abatement or reduction in the Purchase
Price.

                  C. Except for any liens affecting the Property in an amount
not to exceed $150,000.00 which were caused by the direct acts of Seller, Seller
shall have no obligation to expend any amounts due to any lienholder of the
Property which are necessary to obtain a release or discharge of such lien in
order to cure a Title Objection. To the extent Seller agrees to pay any such
sum(s) of money for such purpose, then, at the option of Seller, such sum(s) may
be paid at the Closing from the Purchase Price. In the event any liens affecting
the Property become of record after delivery of the Title Objections which
Seller is not required to discharge as provided for above, then Purchaser's sole
remedy is to either (i) accept such title as Seller is able to convey without
diminution of the Purchase Price or (ii) terminate this Agreement, in which
event Seller shall reimburse Purchaser for its actual costs for title searches,
survey and legal fees, but not to exceed $5,000.00 in the aggregate.

                  D. It is understood and agreed that Seller acquired the
Property at a foreclosure sale and acquired title thereto by way of a Sheriff's
Deed executed and delivered by the Bergen County Sheriff, a copy of which is
annexed hereto as Exhibit C. It is further understood and agreed that the Deed
conveying title to the Property shall convey the same quality of title as that
conveyed to Seller by such Sheriff's Deed.

         5. POSSESSION; TENANCIES.

                  A. Seller shall deliver to Purchaser, and Purchaser shall
accept from Seller, vacant possession of the Property at the Closing, free of
all tenants or occupants.
<PAGE>

                  B. (i) Purchaser acknowledges that the civil action, Borough
of Fort Lee vs. Fort Lee Headquarters Limited Partnership, Red Rock Holdings,
Ltd., Banque National de Paris and DBR Management, Inc. has been adjudicated in
the Superior Court of New Jersey, Chancery Division, Bergen County, Docket No.
BER-C-325-95E (the "Borough Litigation"), pursuant to which the Court terminated
any alleged occupancy rights by the Borough and the Borough has vacated the
Property. Notwithstanding the foregoing, Seller reserves the right, and shall
have the right, without interference from Purchaser, to continue to pursue its
action for monetary relief or damages against the Borough and no such portion of
the Borough Litigation will be assigned to Purchaser. This provision shall
survive the Closing.

                           (ii) Seller represents that there are no tenants or
occupants of the Property as of the Effective Date and Seller covenants not to
grant any leases after the Effective Date.

         6. RISK OF LOSS AND CONDEMNATION.

                  A. Seller assumes the risk of any material loss or damage to
the Property beyond ordinary wear and tear until delivery of the deed to
Purchaser at Closing. If, after the Effective Date, any material portion of the
Property is destroyed or damaged as a result of fire or other casualty (meaning
a casualty the cost of which to repair exceeds $500,000.00), and such repair
shall not have been completed prior to Closing, Seller or Purchaser shall have
the right to terminate this Agreement by delivery of written notice to the other
party within ten (10) calendar days of such casualty, in which event the Escrow
Agent shall return the Deposit to Purchaser and, except as provided for herein,
all rights obligations and liabilities of the parties hereto shall thereupon
terminate. If Purchaser does not have a right to terminate this Agreement or,
having a right to terminate this Agreement, elects not to terminate this
Agreement, then at Closing, Seller shall pay over or assign to Purchaser all
insurance proceeds recovered by Seller and not theretofore used to repair or
restore the Property, less any expenses incurred by Seller in seeking recovery
of such insurance proceeds; provided, however, Purchaser shall be entitled to a
credit against the Purchase Price in an amount equal to the amount of any
deductible maintained by Seller.

                  B. If prior to Closing all or substantially all of the
Property shall be condemned or taken as the result of the exercise of the power
of eminent domain, then this Agreement shall be null and void and of no further
force and effect, in which event Escrow Agent shall return the Deposit to
Purchaser. If prior to the Closing, less than all or substantially all of the
Property shall be condemned or taken as the result of the exercise of the power
of eminent domain, and Purchaser in its reasonable judgment shall determine that
(i) the remaining portion of the Property is not suitable for the continued use
of the Property as an office building, then Purchaser may terminate this
Agreement within five (5) calendar days after receipt of notice thereof or at
the Closing, whichever is earlier, in which event Escrow Agent shall return the
Deposit to Purchaser without further liability hereunder on the part of either
party except as provided for herein, or (ii) the remaining portion of the
Property is suitable for the continued use of the Property, then Seller shall be
entitled to any award
<PAGE>

resulting from any condemnation proceeding, but Purchaser shall be entitled to a
credit against the Purchase Price in an amount equal to said proceeds up to the
amount of the Purchase Price unless such condemnation proceedings shall be
pending on the day of Closing, in which event there shall be no such credit and,
at Closing, Seller shall assign all of its rights and interest in said
proceedings to Purchaser.

         7. REPRESENTATIONS.

                  A. The acceptance of the deed to the Property by Purchaser
shall be deemed an acknowledgment by Purchaser that Seller has fully complied
with, or that Purchaser has waived its right to demand compliance with, all of
Seller's obligations hereunder, and that Seller shall have no further liability
with respect to any of its representations, warranties, covenants or agreements
under this Agreement. All representations made by Seller hereunder or elsewhere
in this Agreement are true and correct to the best of Seller's knowledge and
belief. No representation, warranty, covenant or agreement of Seller shall
survive the Closing.

                  B. Seller's Representations. In order to induce Purchaser to

Agreement and to fulfill its terms; and

                           (ii) The execution, delivery and performance of this
Agreement in accordance with its terms does not violate any contract, agreement,
commitment, order, judgment, decree, law, regulation or ordinance to which

                           (iii) Seller shall continue to maintain liability and
casualty insurance on the Property until the Closing and shall provide evidence

                  C. Purchaser's Representations. In order to induce Seller to
enter into this Agreement, Purchaser warrants and represents that:

                           (i) Purchaser and the person executing this Agreement
on behalf of Purchaser have the right, power and authority to enter into this
Agreement and to fulfill its terms; and

                           (ii) The execution, delivery and performance of this
Agreement in accordance with its terms does not violate any contract, agreement,
commitment, order, judgment, decree, law, regulation or ordinance to which
Purchaser is a party or by which it is bound and constitutes a legal, valid and
binding obligation of Purchaser.

                           (iii) Purchaser represents that Purchaser is a
sophisticated and
<PAGE>

experienced purchaser of properties, such as the Property, and has been duly
represented by counsel in connection with the negotiation of this Agreement and
the purchase of the Property.

         8. CONDITION OF THE PROPERTY; OPERATION OF THE PROPERTY.

                  A. Purchaser acknowledges and agrees (i) that Purchaser has
examined and/or subject to Paragraph 9 hereof, shall have the right to examine,
the Property and is familiar with the condition thereof including any mechanical
or structural defects at the Property; (ii) that except as expressly set forth
in this Agreement, neither Seller, nor the employees, agents or attorneys of
Seller have made any verbal or written representations or warranties whatsoever
to Purchaser, either express or implied; and (iii) that Purchaser has not relied
on any representations or warranties except those expressly set forth in this
Agreement. Specifically, without limitation, no representations or warranties
have been made to Purchaser with respect to: (i) the physical condition of the
Property; (ii) the environmental condition of the Property; (iii) the
applicability to the Property of any particular statues, laws, codes,
ordinances, regulations or rules, or the compliance of the Property therewith,
including, without limitation, zoning, building and health codes, regulations
and ordinances; and (iv) the expenses of or in respect of the Property.
Purchaser agrees to accept the Property "AS-IS, WHERE-IS and WITH ALL FAULTS" at
the Closing, including any latent or patent defects in or affecting the
Property. Purchaser and any person or entity claiming by or under Purchaser,
shall at the Closing be deemed to have released Seller and its affiliates,
employees, officers, directors, representatives and agents from any and all
claims, costs, losses, liabilities, damages, expenses, demands or causes of
action now or hereafter arising from or related to any matter of any kind or
nature relating to the Property.

                  B. From and after the Effective Date until the Closing, Seller
shall maintain the Property in its present condition, subject to ordinary wear
and tear, except as provided for herein. Seller represents that the day to day
operation and maintenance of the Property is presently in the care, custody and
control of Quinlan Properties, L.P. ("Quinlan") pursuant to a written property
management agreement dated May 20, 1996, a copy of which has been delivered to
Purchaser. Purchaser may, at its election, assume Seller's obligations under
said management agreement or request that Seller cancel such management
agreement at the Closing. Seller shall be responsible for any cancellation
penalty incurred as a result of such cancellation. To the best of Seller's
knowledge, there are no service contracts presently in effect which are not
terminable, without penalty, on thirty (30) calendar days' written notice.
Purchaser may, at its election, assume Seller's obligations under said service
contracts or request that Seller cancel such service contracts at the Closing. A
list of all such service contracts is annexed hereto and made a part hereof as
Exhibit D.

                  C. From and after the Effective Date until the Closing, Seller
shall not, without the prior written consent of Purchaser, which consent
Purchaser agrees it shall not unreasonably withhold or delay, enter into any new
service contract unless the same shall not be binding on Purchaser after the
Closing or shall be cancelable, without penalty, upon not more than thirty (30)
calendar days' written notice (unless Purchaser, in its sole discretion,
<PAGE>

elects to accept the same).

         9. DUE DILIGENCE REVIEW.

                  A. From and after the Effective Date until 5:00 P.M. (New York
time) on the first business day which is fifteen (15) days after the Effective
Date or sooner if Seller and Purchaser mutually agree (such period being
hereinafter referred to as the "Due Diligence Period"), Purchaser and
Purchaser's agents, at Purchaser's sole cost and expense, shall have the right
to enter upon the Property in order to make such physical inspection of the
Property as Purchaser deems reasonably necessary and appropriate. If any
inspections are performed on the Property, Purchaser shall keep the Property in,
or restore the Property to, its physical condition as of the Effective Date.
Prior to such entry or inspection, Purchaser, or its designated representatives
or agents who will perform such inspections, (i) shall obtain liability
insurance in form, substance, coverage and amounts reasonably acceptable to
Seller and (ii) shall deliver certificates of such insurance to Seller. Such
insurance shall continue until the Closing. Notwithstanding anything to the
contrary set forth in the foregoing, in exercising its rights under this
Paragraph, Purchaser shall not interfere otherwise with the normal operation,
use, occupancy, management or maintenance of the Property.

                  B. Purchaser agrees to indemnify and hold Seller harmless from
and against any claim, suit or damage arising out of Purchaser's entry and/or
inspections on or about the Property. Such indemnity shall survive any
termination of this Agreement.

                  C. In the event that any such examinations, reviews and/or
inspections cause Purchaser, in its sole discretion, to believe that the
Property is not suitable for Purchaser's purposes, then Purchaser may, at any
time during the Due Diligence Period, terminate this Agreement by giving written
notice of such termination to Seller, whereupon the parties hereto shall be
released from any and all liability and obligation hereunder, except as
expressly provided herein, and the Deposit shall be returned to Purchaser
forthwith.

                  D. In the event Purchaser does not terminate this Agreement on
or prior to the last day of the Due Diligence Period as provided herein, as to
which date TIME IS OF THE ESSENCE, Purchaser shall no longer have the right to
terminate this Agreement but shall have the continued right until Closing to
inspect, survey and make other examinations of the Property, subject in all
cases to Purchaser's indemnification and restoration obligations set forth in
this Paragraph 9.

                  E. In the event Purchaser does not cancel this Agreement at
the end of the Due Diligence Period, Purchaser shall be deemed to have (i)
represented and warranted that it has inspected all of the Property and the
Property Documents and that in such inspection Purchaser has not discovered any
material matter which would form the basis for a claim by Purchaser that the
Property is not in the condition agreed to or that Seller has breached any
representation, warranty, covenant or agreement of Seller made in this Agreement
relating to the Property or the Property Documents and that Purchaser has no
actual knowledge of any
<PAGE>

such matter and (ii) waived any claim that Purchaser may have against Seller and
released Seller from any such claim now or hereafter arising from or related to
any matter of any kind or nature relating to the Property.

                  F. Upon termination of this Agreement, neither party shall
have liability to the other, except that (i) Purchaser's indemnification and
restoration obligations set forth herein shall survive as set forth in such
provisions, (ii) Purchaser shall be obligated to deliver to Seller any reports
that were performed by or on behalf of Purchaser with respect to the Property,
and (iii) Purchaser shall return all copies of all confidential information
furnished to Purchaser or Purchaser's agents by Seller.

                  G. Upon the execution and delivery of this Agreement by Seller
and Purchaser, or as soon thereafter as reasonably possible, in addition to
those materials heretofore provided to Purchaser by Seller or the Broker (as
hereinafter defined), Seller shall make available, or cause Quinlan to make
available, to Purchaser for its inspection during normal business hours at
Quinlan's offices those documents in Seller's possession affecting the ownership
and operation of the Property (the "Property Documents"). Purchaser, at its sole
cost and expense, may make copies of the Property Documents but may not remove
the originals from Quinlan's offices. Contemporaneously with the delivery of
copies of the Property Documents, Purchaser shall sign an inventory list of the
copies of the Property Documents so delivered to Purchaser for Purchaser's
inspection and/or copying, acknowledging receipt of such Property Documents.

                  H. Purchaser acknowledges that all information in respect of
the Property furnished, or to be furnished, to Purchaser has been and will be so
furnished on the condition that Purchaser maintain the confidentiality thereof.
Accordingly, Purchaser shall, and shall cause its directors, officers and other
employees and representatives to hold in strict confidence, and not disclose to
any other party without the prior written consent of Seller until the Closing
shall have been consummated, any of the information in respect of the Property
delivered to Purchaser by Seller or any of its agents, representatives or
employees. In the event the Closing does not occur and this Agreement is
terminated, Purchaser shall promptly return to Seller all originals and copies
of all such information without retaining any copy thereof or extract therefrom.
Notwithstanding anything to the contrary hereinabove set forth, Purchaser may
disclose such information (i) on a need-to-know basis to its employees or
members of professional firms serving it in connection with this transaction,
(ii) as is requested by a reputable institutional lender in connection with any
financing of the purchase of the Property, and (iii) as any governmental agency
may require in order to comply with applicable laws or regulations; provided,
however, that all such individuals and/or entities shall agree in writing to be
bound by the confidentiality provisions of this Agreement and that Purchaser
shall indemnify Seller with respect to any breach of such agreement by any such
person and/or entity. The provisions of this Section shall survive the Closing
or earlier termination of this Contract.

         10. MUNICIPAL INSPECTION. Purchaser, at its sole expense, shall be
<PAGE>

responsible to obtain a Certificate of Occupancy and/or all other municipal
certificates or approvals that may be required to convey the Property, to occupy
the Property, or to maintain business operations thereon.

         11. NO FINANCING CONTINGENCY. Purchaser represents and warrants that
the consummation of this transaction by Purchaser is not contingent or
conditioned upon Purchaser's obtaining any financing and that Purchaser has, or
will have at the time of Closing, sufficient cash to complete the purchase.

         12. ASSESSMENTS. If at the Closing the Property or any part thereof
shall be or shall have been affected by any assessments which are or may become
payable in annual installments of which the first installment is then due or has
been paid, then for the purposes of this Agreement all the unpaid installments
of any such assessment, including those which are to become due and payable
after the delivery of the deed, shall be assumed by Purchaser. The cost of all
other assessments for work commenced after the date of this Agreement will be
borne by Purchaser.

         13. CLOSING OF TITLE. The closing of title (the "Closing") shall take
place on the first business day which is thirty (30) days after the expiration
of the Due Diligence Period (the "Closing Date"), at 11:00 A.M. at the offices
of Wolff & Samson, 5 Becker Farm Road, Roseland, New Jersey 07068, or at such
other location reasonably acceptable to the parties.

         14. ASSIGNMENT. This Agreement may not be assigned by Purchaser without
the prior written consent of Seller.

         15. BROKERAGE. Each party represents and warrants to the other that it
dealt with no broker or other person entitled to claim fees for such services in
connection with the negotiation, execution and delivery of this Agreement other
than CB Commercial Real Estate Group, Inc. and Plawker Real Estate, Inc.
(collectively, the "Broker"). Seller agrees to pay Broker a commission pursuant
to a separate agreement with Broker. Based upon the aforesaid warranty and
representation, each party agrees to defend, indemnify and hold the other party
harmless from and against any and all claims for finders' fees or brokerage or
other commissions which may at any time be asserted against the indemnified
party founded upon a claim that the substance of the aforesaid representation of
the indemnifying party is untrue, together with any and all losses, damages,
costs and expenses, including reasonable attorneys' fees and disbursements,
relating to such claims or arising therefrom or incurred by the indemnified
party in connection with this indemnification provision. The provisions of this
Paragraph 15 shall survive the Closing.

                  G. Notwithstanding the foregoing provisions of (C) and (D)
above, if Escrow Agent shall have received a written notice of objection from
Seller or Purchaser, or shall have received at any time before actual
disbursement of the Deposit a written notice signed by either Seller or
Purchaser advising that litigation between Seller and Purchaser over entitlement
to the Deposit has been commenced, or shall otherwise believe in good faith at
any time that a disagreement or dispute has arisen between the parties hereto
over entitlement to the Deposit (whether or not litigation has been instituted),
Escrow Agent shall have the right, upon written notice to both Seller and
Purchaser, (i) to deposit the Deposit with the Clerk of the Court in which any
litigation is pending, and/or (ii) to take such affirmative steps as it may, at
its option, elect in order to terminate its duties as Escrow Agent, without
limitation, the depositing of the Deposit with a court of competent jurisdiction
and the commencement of an action for interpleader, the costs thereof to be
borne by whichever of Seller or Purchaser is the losing party, and thereupon
Escrow Agent shall be released of and from all liability hereunder except for
any previous gross negligence or willful default.

                  H. Escrow Agent shall have no duty to invest all or any
portion of the Deposit during any period of time Escrow Agent may hold the same
prior to disbursement thereof except in one or more interest-bearing accounts as

be made by Escrow Agent shall be with such interest, if any, as shall have been
earned thereon.

                  I. Purchaser acknowledges that Escrow Agent is also counsel to
Seller and shall have the right to represent Seller in any dispute between
Seller and Purchaser regarding the disposition of the Deposit or otherwise.

                  J. Escrow Agent shall be under no obligation to deliver any
instrument or documents to a court or take any other legal action in connection
with this Agreement or towards its enforcement, or to appear in, prosecute or
defend any action or legal proceeding which, in Escrow Agent's opinion, would or
might involve it in any cost, expense, loss or liability unless, as often as
Escrow Agent may require, Escrow Agent shall be furnished with security and
indemnity satisfactory to it against all such costs, expenses, losses or
liabilities.

                  K. Escrow Agent shall not be liable for any error in judgment
or for any act done or omitted by it in good faith, or for any mistake of fact
or law, and is released and exculpated from all liability hereunder except for
willful misconduct or gross negligence.

                  L. Escrow Agent's obligations hereunder shall be as a
depositary only, and Escrow Agent shall not be responsible or liable in any
manner whatever for the sufficiency, correctness, genuineness or validity of any
notice, written instructions or other instrument furnished to it or deposited
with it, or for the form of execution of any thereof, or for the identity or
authority of any person depositing or furnishing same.

                  M. Escrow Agent shall not have any duties or responsibilities
except those set forth in this Paragraph 29, and shall not incur any liability
in acting upon any signature,
<PAGE>

notice, request, waiver, consent, receipt or other paper or document believed by
it to be genuine, and Escrow Agent may assume that any person purporting to give
any notice or advice on behalf of any party in accordance with the provisions
hereof has been duly authorized to do so. Seller and Purchaser hereby jointly
and severally indemnify and agree to hold and save Escrow Agent harmless from
and against any and all loss, damage, cost or expense Escrow Agent may suffer or
incur as Escrow Agent hereunder unless caused by its gross negligence or willful
default.

                  N. Escrow Agent shall be entitled to consult with counsel in
connection with its duties hereunder. Seller and Purchaser agree to reimburse
Escrow Agent for all costs and expenses incurred by Escrow Agent in performing
its duties as Escrow Agent including, but not limited to, attorneys' fees
(either paid to retained attorneys or amounts representing the fair value of
legal services rendered to itself).

                  O. The terms and provisions of this Paragraph 29 shall create
no right in any person, firm or corporation other than the parties hereto and
their respective successors and permitted assigns, and no third party shall have
the right to enforce or benefit from the terms hereof.

         30. NO OFFER. The submission of this Agreement for examination does not

Agreement the day and year first above written.

                  Pryor, Cashman, Sherman & Flynn ("Escrowee"), the receipt of

                  referred
                         to as the "Deposit"); and

                  b) Upon closing of title in accordance with the terms hereof,
                  the balance of the Purchase Price shall be paid by Purchaser
                  to Seller as follows: (i) by Purchaser accepting all other
                  rights of Seller in and to the Premises, subject to a certain
                  mortgage (the "NYL
<PAGE>

                  Mortgage") dated September 21, 1990, recorded in Book 2070 at
                  Page 142 of the Greenwich Land Records and (ii) by payment to
                  Seller, by unendorsed certified or official bank check payable
                  to Seller or, at Seller's option, by wire transfer to an
                  account designated by Seller, in an amount equal to the
                  difference between the unpaid balance of the Purchase Price
                  and the unpaid principal balance of the NYL Mortgage due at
                  the time of Closing; plus or minus prorations as provided
                  herein and any unpaid amounts due or owing under the NYL
                  Mortgage, other than the principal balance, both as of the
                  Closing Date.

    2.02 (a) The sum payable pursuant to Section 2.01(a) hereof shall be paid to
Escrowee, to be held in escrow in a special bank account until the Closing or
sooner termination of this Agreement, and Escrowee shall pay over or apply such
proceeds in accordance with the terms of this section. Escrowee shall hold such
sums in an interest-bearing account and all such interest shall be paid to
Purchaser, unless the Deposit is to be paid to Seller as provided herein on
account of Purchaser's default, in which event the interest shall be paid to
Seller. The party receiving such interest shall pay any income taxes thereon. At
the Closing, such sums shall be paid by Escrowee to Seller. If for any reason
the Closing does not occur and either party makes a written demand upon Escrowee
for payment of such amount, Escrowee shall give written notice to the other
party of such demand. If Escrowee does not receive a written objection from the
other party to the proposed payment within ten (10) business days after the
giving of such notice, Escrowee is hereby authorized to make such payment. If
Escrowee does receive such written objection within such ten (10) day period,
Escrowee shall continue to hold such amount until otherwise directed by written
instructions from the parties to this Agreement or a final judgment of a court.
However, Escrowee shall have the right at any time to deposit the escrowed sums
and interest thereon, if any, with the clerk of the highest court of original
jurisdiction of the county in which the Land is located. Escrowee shall give
written notice of such deposit to Seller and Purchaser. Upon such deposit,
Escrowee shall be relieved and discharged of all further obligations and
responsibilities hereunder. In no event shall the firm of Pryor, Cashman,
Sherman & Flynn be disqualified from continuing to act as
<PAGE>

Purchaser's attorney by virtue of having acted as Escrowee hereunder.

                  (b) The parties acknowledge that Escrowee is acting solely as
a stakeholder at their request and for their convenience, that Escrowee shall
not be deemed to be the agent of either of the parties, and that Escrowee shall
not be liable to either of the parties for any act or omission on its part
unless taken or suffered in bad faith, or involving gross negligence. Seller and
Purchaser shall jointly and severally indemnify and hold Escrowee harmless from
and against all costs, claims and expenses, including reasonable attorneys' fees
incurred in connection with the performance of Escrowee's duties hereunder,
except with respect to actions or omissions taken or suffered by Escrowee in bad
faith, or involving gross negligence on the part of Escrowee.

                  (c) Escrowee has acknowledged its agreement to these
provisions, and does in addition agree to submit itself to the jurisdiction of
the Superior Court of the State of Connecticut in any controversy relating to
the Deposit, by signing in the place indicated on the signature page of this
Agreement.

                  (d) In the event Purchaser fails to perform on the Closing
Date, Purchaser's sole liability and Seller's sole recourse shall be limited to
the amount of the Deposit. Seller agrees that retention of the Deposit
constitutes fixed and liquidated damages resulting from Purchaser's default, and
Seller waives any other claim, at law or in equity, either against Purchaser or
against any person, known or unknown, disclosed or undisclosed.

                  (e) (i) If, after complying with the terms of this Agreement,
Seller is unable to convey title in accordance with the terms of this Agreement,
Purchaser shall have the right to terminate this Agreement. In such event,
neither party shall have any further rights or obligations hereunder other than
those which are expressly stated herein to survive any such termination, the
Deposit shall be returned to Purchaser and Seller shall refund to Purchaser all
charges made for (a) examining the title to all of the Real Property, (b) any
appropriate additional municipal searches made in accordance with this
Agreement, and (c) survey and survey inspection charges, which refund obligation
shall survive said termination.

                         (ii)   In the event of any default on the part
of the Seller, Purchaser shall have the right to terminate
this Agreement or commence an action seeking specific
<PAGE>

performance.

                         (iii)  In the event of a wilful default on the
part of the Seller, Purchaser shall be entitled to any and all
of its rights and remedies at law or in equity.

                                                 Contingencies

    4.01 Purchaser's obligations hereunder are contingent upon satisfaction of
the following condition not later than forty-five (45) days next following the
date of this Agreement (said forty-five (45) day period being referred to herein
as the "Inspection Contingency Period"): Satisfaction of Purchaser, in
Purchaser's sole discretion of the results of Purchaser's inspection and
assessment of the Premises, including without limitation, environmental, soil
tests and borings, groundwater tests and investigations, physical, structural,
sub-surface soil, zoning, regulatory and financial aspects of the Premises and
its present or proposed use and occupancy, and such other tests, investigations
or studies as Purchaser, in its sole discretion, determines is necessary. All
such inspections and assessments shall be conducted at Purchaser's sole cost and
expense. Seller, at no cost to Seller, shall cooperate with Purchaser in such
inspection of the Premises and shall permit Purchaser access to the Premises and
to Sellers' books and records relating to the Premises including, without
limitation environmental reports and studies. In addition, Seller will deliver
to Purchaser, promptly after request, true and complete copies of all test
borings, Environmental Documents (as defined in Section 5.23(d)), surveys, title
materials and engineering and architectural data and the like relating to the
Premises that are in Seller's possession or under its control. In the event
<PAGE>

any additional similar materials or information come within Seller's possession
or control after the date of this Agreement, Seller shall promptly submit true
and complete copies of the same to Purchaser. All such rights of access shall be
exercised at reasonable times and upon reasonable prior notice to Seller and
shall be exercised in a manner which will not cause damage to the Premises nor
interfere in any material respect with the operation of any Building tenant, and
Purchaser shall repair and restore any portion of the surface of the Premises
disturbed by Purchaser, its agents or contractors during the conduct of any test
or study to substantially the same condition as existed prior to such
disturbance. Such right of access shall include, without limitation, the right
to perform studies, tests, borings, investigations and inspections for the
purposes described in Section 4. Provided that Purchaser shall first deliver to
Seller a detailed workplan showing the location of all borings studies,
investigations and testing to be performed by or on behalf of Purchaser, Seller
shall notify Purchaser of any dangerous conditions on the Premises, including,
without limitation, conditions which due to the nature of the borings, studies,
investigations, inspections or testing to be performed by or on behalf of
Purchaser may pose a dangerous condition to Purchaser or Purchaser's agents and
contractors. Such right of inspection and the exercise of such right shall not
constitute a waiver by Purchaser of the breach of any representation, warranty,
covenant or agreement of Seller which might, or should, have been disclosed by
such inspection.

    4.02 Purchaser shall, prior to the expiration of the Inspection Contingency
Period, give written notice to Seller if Purchaser, decides to terminate this
Agreement for any reason. This Agreement shall be terminated if Purchaser shall
fail to give written notice ("Continuation Notice") to Seller not later than
5:00 p.m. of the last day of the Inspection Contingency Period, to Seller and to
Escrowee that Purchaser elects to continue the effectiveness of this Agreement,
and in the absence of such written notice, the Deposit shall be returned to
Purchaser and thereupon no party hereto shall have any further rights or
obligations hereunder but shall be released therefrom. In the event that
Purchaser shall so give to Seller such Continuation Notice, this Agreement shall
remain in full force and effect, and Purchaser shall have no further right to
terminate this Agreement pursuant to this Section 4. However, Purchaser shall
continue to have the rights of access and inspection set forth in this Section
4.

                                                  Apportionments

    12.02 If any tenant is in arrears in the payment of rent on the Closing

adjusted as soon as practicable after the Closing.

    12.05 The provisions of this Section 12 shall survive the Closing Date.


                                                    Section 13

                                      Objections to Title, Failure of Seller
                                     or Purchaser to Perform and Vendee's Lien

    13.01 Purchaser has ordered an examination of title and shall cause a copy
of the title report to be forwarded to Seller's attorney upon receipt.

    13.02 If, upon the date for the delivery of the deed as hereinafter
provided, the Seller shall be unable to deliver or cause to be delivered good
and marketable title to said premises, subject only to the Permitted Exceptions,
then the Seller shall be allowed a reasonable postponement of closing not to
exceed thirty (30) days, within which to perfect title. If at the end of said
time the Seller is still unable to deliver or cause to be delivered a deed or
deeds conveying a good and marketable title to said Premises, subject only to
the Permitted Exceptions, then the Purchaser may elect to accept such title as
the Seller can convey, without modification of the Purchase Price, or may reject
such title, whereupon all sums paid on account hereof, together with any
expenses actually incurred by the Purchaser for survey costs and title insurance
costs shall be paid to the Purchaser without interest thereon. Upon such
payment, this Agreement shall terminate and the parties hereto shall be released
and discharged from all further claims and obligations.


    13.03 If title to the Premises is subject to any lien or charge other than
the Permitted Encumbrances, Seller agrees to use good faith efforts to cause the
Premises to be subject only to the Permitted Encumbrances and in any event to
cure, at its expense, (i) judgments against Seller, (ii) mortgages (other than
the NYL Mortgage) or other liens which can be satisfied by payment of a
liquidated amount and (iii) defects, objections or exceptions which can be
removed by payments not to exceed one (1%) percent of the Purchase Price in the
aggregate. Seller agrees and covenants that it shall not voluntarily place any
defects, objections or exceptions to title to any of the Premises
<PAGE>

from and after the date of the first issuance of the title
commitment for said Premises.

    13.04 It shall be a condition to Closing that Seller convey, and that the
Title Company insure, title to the Premises in the amount of the Purchase Price
(at a standard rate for such insurance) in the name of Purchaser or its
designees, after delivery of the Deed, by a standard 1992 ALTA Owners Policy,
with ALTA endorsements Form 3.1, Form 8.1, Form 9 and any other endorsements as
required by Purchaser attached, free and clear of all liens, encumbrances and
other matters, other than the Permitted Encumbrances (the "Title Policy"). The
Title Company shall provide affirmative insurance that any (i) Permitted
Encumbrances have not been violated, and that any future violation thereof will
not result in a forfeiture or reversion of title; (ii) Purchaser's contemplated
use of the Premises will not violate the Permitted Encumbrances; and (iii) the
exception for taxes shall apply only to the current taxes not yet due and
payable. Seller shall provide such affidavits, including title affidavits and
survey affidavits of no change, and undertakings as the Title Company insuring
title to the Premises may reasonably require. The words "insurable title" and
"insurable" as used in this Agreement are hereby defined to mean title which is
insurable at standard rates (without special premium) by the Title Company
without exception other than the Permitted Encumbrances, provided that any
additional premium payable with respect to the aforesaid affirmative insurance
shall be Purchaser's obligation.

    13.05 Any unpaid taxes, water charges, sewer rents and assessments, together
with the interest and penalties thereon to a date not less than seven (7)
business days following the Closing Date (in each case subject to any applicable
apportionment), and any mortgages or other liens created by Seller, which Seller
is obligated to pay and discharge pursuant to the terms of this Agreement,
together with the cost of recording or filing of any instruments necessary to
discharge such liens and such judgments, shall be paid at the Closing by Seller.
Seller shall deliver to Purchaser, on the Closing Date, instruments in
recordable form sufficient to discharge any such mortgages or other liens which
Seller is obligated to pay and discharge pursuant to the terms of this
Agreement.

    13.06 If the Title Commitments disclose judgments, bankruptcies or other
returns against other persons having names the same as or similar to that of
Seller, Seller, on request, shall deliver to the Title Company affidavits
showing that such judgments, bankruptcies or other returns are not against
Seller, or any affiliates. Upon request by Purchaser, Seller shall
<PAGE>

deliver any affidavits and documentary evidence as are reasonably required by
the Title Company to eliminate the standard or general exceptions on the ALTA
form Owner's Policy.

    13.07 If, on the Closing Date, the Premises or any part thereof shall be or
shall have been affected by an assessment or assessments which are or may become
payable in annual install ments, of which the first installment is either then a
charge or lien or has been paid, then for the purposes of this Agreement all the
unpaid installments of any such assessment, including those which are to become
due and payable after the Closing Date, shall be deemed to be due and payable
and to be liens upon the Premises and shall be paid and discharged by Seller on
the Closing Date.

real estate broker other than Gladstone Properties in connection with this

an exclusive listing or brokerage agreement with respect to the sale to
Purchaser of the Leasehold, the Premises or the Land. Seller and Purchaser shall
indemnify and defend each other against any costs, claims or expenses, including
attorneys' fees, arising out of the breach, as judicially determined, on their
respective parts of any of their respective representations, warranties or
agreements contained in this paragraph. The representations and obligations
under this paragraph shall survive the Closing or, if the Closing does not
occur, the termination of this Agreement.

periods specified and if no time period is specified by the Outside Date.

                  3.1 TITLE CONDITION.

                             3.1.1 Seller has requested from the Title Company
a current ALTA coverage preliminary report for the Property (the "Preliminary
Report"), together with copies of all documents available to the Title Company
referenced as recorded exceptions in the Preliminary Report.

                             3.1.2 Buyer shall have until the last day of the
Title Approval Period to secure from the Title Company a commitment for title
insurance coverage in a form and with exceptions and endorsements acceptable to
Buyer in its sole and absolute discretion (the "Title Policy"). By the end of
the Title Approval Period, Buyer shall provide written notice to Seller and
Escrow Holder as to whether Buyer has received from the Title Company a
commitment for the Title Policy acceptable to Buyer in its sole and absolute
discretion (either "Title Approval Notice" or "Title Rejection Notice"). In
order to be effective, the Title Approval Notice, if given, shall also contain a
copy of the Title Policy which will be required for purposes of satisfying
Buyer's Paragraph 3.8 condition precedent to its performance. If Seller and
Escrow Holder receive a Title Approval Notice from Buyer by the end of the Title
Approval Period, this title condition shall be conclusively deemed satisfied in
all respects. If Seller and Escrow Holder do not receive either form of written
notice, or receive the Title Rejection Notice by the end of the Title Approval
Period, Escrow and this Agreement shall terminate and the Deposit shall be
returned to Buyer, as provided in Paragraph 6.3.

                             3.1.3 Upon the Close of Escrow, Buyer shall be
deemed to have purchased the Property subject to the following:

                                       (a) Any and all exceptions to title shown
in the Title Policy;

                                       (b) All matters which could be revealed
or disclosed by physical inspection and an accurate survey of the Property;
<PAGE>

                                       (c) General, special and supplemental
real property taxes and assessments not yet due and payable; and

                                       (d) Any and all Leases, rights of vendors
and holders of security interests on personal property installed upon the
Property by tenants, and the rights of tenants to remove personal property
and/or fixtures at the expiration of the term of such Leases.

                             3.1.4     Nothing in this Paragraph 3.1 shall
obligate Buyer or Seller to expend any funds to cure any title defects unless
the parties have expressly committed to do so in writing. However, if after the
effective date of the Preliminary Report and the endorsements thereto (the last
of which dated December 22, 1997, the Title Company supplements the Preliminary
Report such that new monetary liens are shown as exceptions to the Title Policy,
and such new monetary lien exceptions arose from written contracts executed by
Seller, Seller shall cause such monetary lien exceptions to be removed from the
Title Policy.

                  3.2        FEASIBILITY CONDITION.

                             3.2.1     Buyer shall have until 5:00 p.m. on the
last day of the Feasibility Period to confirm, in Buyer's sole and absolute
discretion, and at Buyer's sole expense, whether Buyer may feasibly acquire and
use the Property for Buyer's intended purpose. During the Feasibility Period,
Buyer shall, in addition to all other matters regarding the Property, have
reviewed (or shall have assumed the risk of not reviewing) all of the following:

                                       (a)
    the physical condition of the Property;

                                       (b)
    the availability of all necessary utilities and gravity sewers
and storm drains for the Property;

                                       (c)
    the Leases;

                                       (d)
    building inspection reports, roof inspection reports, building plans, HVAC
inspection reports, soils reports, and engineering reports to the extent
available;

                                       (e)

improvements, the Buildings, surface and subsurface, including the existence of
toxic waste and hazardous substances;

                                       (i)
    the economic feasibility of Buyer's intended use of the
Property;

                                       (j)
    the ability of Buyer to secure funds sufficient to purchase the
Property; and

                                       (k)
    any other matters which are or may be relevant to Buyer's
decision whether or not to purchase the Property.

                             3.2.2 By the end of the Feasibility Period, Buyer
shall provide written notice to Seller and Escrow Holder as to whether Buyer
approves (in its sole and absolute discretion) the feasibility of acquiring the
Property (either "Feasibility Notice" or "Non-Feasibility Notice"). If Seller
and Escrow Holder receive a Feasibility Notice from Buyer by the end of the
Feasibility Period, this feasibility condition shall be conclusively deemed
satisfied in all respects including Buyer's approval of each of the items set
out in Paragraph 3.2.1. If Seller and Escrow Holder do not receive either form
of written notice, or receive the Non-Feasibility Notice, by the end of the
Feasibility Period, Escrow and this Agreement shall terminate, and the Deposit
shall be returned to Buyer, as provided in Paragraph 6.3.

                             3.2.3     Prior to the Close of Escrow, or in the
event the Close of Escrow never occurs, Buyer hereby agrees that any information
(whether written or verbal), reports, materials, studies or other work product,
which it now has or may obtain pursuant to the provisions of this Agreement,
shall remain strictly confidential. Prior to the Close of Escrow, or in the
<PAGE>

event the Close of Escrow never occurs, Buyer shall use reasonable efforts not
to reveal the existence or contents of any such items to any of its employees,
agents, representatives, or affiliates (except as reasonably required in
connection with Buyer's evaluation of the Property) or to governmental or
quasi-governmental agencies or bodies. Buyer and Seller, for themselves and
their affiliates, subsidiaries, agents, and employees and retained
professionals, agree to keep this Agreement and all of its terms confidential
both prior to Close of Escrow and to not make any public announcements or public
disclosures or communicate with any media with respect to the subject matter
hereof without the prior written consent of the other party (in their sole and
absolute discretion), provided, however, that each party shall have the right to
make such disclosures as are required by law, including but not limited to
required disclosures to the Securities and Exchange Commission, the New York
Stock Exchange (which disclosure of this entire Agreement shall be made in
printed or electronic fashion), or needed for the transaction to occur (e.g.,
consultants, capital sources, affiliates, officers, directors, shareholders and
employees) which disclosures shall not include, unless specifically required by
law, the identity of the Seller or the Purchase Price.

                             3.2.4       BUYER ACKNOWLEDGES THAT (1) BUYER HAS
RECEIVED COPIES OF THE ENVIRONMENTAL REPORTS LISTED ON EXHIBIT J ATTACHED HERETO

                             (b)   The terms "Close of Escrow" and/or

<PAGE>

    6. TERMINATION OF THIS AGREEMENT.

                  6.1 FAILURE TO CLOSE BY OUTSIDE DATE. If Escrow fails to close
as of 5:00 p.m. on the Outside Date, this Agreement and Escrow shall
automatically terminate and cancel without further action by Escrow Holder or
any party and notwithstanding any provision contained in Escrow Holder's general
provisions.

                  6.2 FAILURE OF A CONDITION. Except in those instances where
this Agreement and Escrow automatically terminate under the terms of this
Agreement, if any condition is not satisfied or waived within the time period
and in the manner set forth in this Agreement, then the party for whose benefit
the condition exists (as provided in Paragraphs 3 and 4 of this Agreement) may
terminate this Agreement by delivering written notice to the other party and to
Escrow Holder by no later than the earliest of (i) the third (3rd) business day
following the expiration of such applicable time period, (ii) the Closing Date,
or (iii) the Outside Date.

                  6.3 CONSEQUENCES. If this Agreement terminates (or is properly
terminated by either party) as specifically provided by its terms, then each of
the following shall occur: (i) Escrow shall be deemed automatically canceled
regardless of whether cancellation instructions are signed; (ii) neither party
shall have any further obligation to the other under this Agreement (except for
breach of this Agreement as those remedies may be limited hereunder; and as
provided under Paragraphs 10.2 and 15.2 which shall survive termination of this
Agreement); (iii) all rights granted to Buyer under this Agreement and in the
Property shall terminate; and, (iv) except as provided to the contrary in
Paragraph 6.5 (concerning Seller's right to retain the Deposit as liquidated
damages), Escrow Holder shall return all funds and documents then held in Escrow
to the party depositing the same, including, without limitation, the Deposit to
Buyer.

                  6.4 ESCROW CANCELLATION CHARGES. If Escrow fails to close
because of either party's default, the defaulting party shall be liable for all
Escrow cancellation and Title Company charges. If Escrow fails to close for any
other reason, Buyer and Seller shall each pay one-half of any Escrow
cancellation and Title Company charges.

                  6.5        LIQUIDATED DAMAGES.  IF ESCROW FAILS TO CLOSE DUE
TO BUYER'S BREACH OF THIS AGREEMENT, SELLER SHALL BE RELEASED
FROM ALL OF ITS OBLIGATIONS UNDER THIS AGREEMENT, AND ESCROW
HOLDER SHALL IMMEDIATELY DELIVER THE DEPOSIT TO SELLER, AND
<PAGE>

SELLER SHALL BE ENTITLED TO RETAIN THE DEPOSIT AS LIQUIDATED DAMAGES. SELLER AND
BUYER SHALL INDEMNIFY ESCROW HOLDER FOR ANY LIABILITY, COSTS AND EXPENSES BY
REASON OF ESCROW HOLDER'S GOOD FAITH COMPLIANCE WITH THIS PARAGRAPH. THE PARTIES
EXPRESSLY AGREE THAT THE AMOUNT OF THE DEPOSIT IS A REASONABLE ESTIMATE OF THE
EXTENT TO WHICH SELLER WOULD BE DAMAGED BY BUYER'S BREACH OF THIS AGREEMENT, IN
LIGHT OF THE DIFFICULTY THE PARTIES WOULD HAVE IN DETERMINING SELLER'S ACTUAL
DAMAGES AS A RESULT OF SUCH BREACH BY BUYER. SELLER'S RETENTION OF THE DEPOSIT
AS LIQUIDATED DAMAGES SHALL BE SELLER'S EXCLUSIVE REMEDY FOR DAMAGES BY REASON
OF BUYER'S BREACH OF THIS AGREEMENT. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN
THIS PARAGRAPH 6.5, THE DEPOSIT SHALL NOT LIMIT THE SELLER'S RIGHT TO RECOVERY
UNDER PARAGRAPHS 10.2 AND 15.2. OTHER THAN A RELEASE BY ESCROW AGENT OF DEPOSIT
TO SELLER AS PART OF THE CLOSING OR TO BUYER IF THIS AGREEMENT IS TERMINATED AT
END OF THE DUE DILIGENCE, ESCROW HOLDER SHALL HOLD AND DISBURSE THE DEPOSIT
PURSUANT TO THIS AGREEMENT OR SUBSEQUENT WRITTEN AGREEMENT OF THE PARTIES, IN
ACCORDANCE WITH THE TERMS AND CONDITIONS OF THIS AGREEMENT OR ANY SUCH
SUBSEQUENT AGREEMENT. IN THE EVENT OF DOUBT AS TO ITS DUTIES OR LIABILITIES
UNDER THE PROVISIONS OF THIS AGREEMENT, ESCROW HOLDER MAY IN ITS SOLE DISCRETION
CONTINUE TO HOLD THE DEPOSIT UNTIL THE PARTIES MUTUALLY AGREE TO DISBURSEMENT
THEREOF, OR UNTIL A COURT OF COMPETENT JURISDICTION SHALL DETERMINE THE RIGHTS
OF THE PARTIES THERETO.

                  SELLER'S INITIALS
                             BUYER'S INITIALS

    7. GENERAL ESCROW PROVISIONS.

                  7.1 ESCROW INSTRUCTIONS. This Agreement when signed by Buyer
and Seller shall also constitute Escrow Instructions to Escrow Holder.

                  7.2 OPENING OF ESCROW. When both (i) this Agreement, fully
signed or in signed counterparts, and (ii) Buyer's Deposit are delivered to
Escrow Holder, Escrow shall be deemed open, and Escrow Holder shall immediately
notify Buyer and Seller by telephone and in writing of the date of Opening of
Escrow.

                  7.3 GENERAL PROVISIONS. Notwithstanding anything to the
contrary in this Agreement, the General Provisions of Escrow Holder, if any,
which are later signed by the parties, are incorporated by reference to the
extent they are not inconsistent with the provisions of this Agreement. If there
is any inconsistency between the provisions of those General Provisions
<PAGE>

and any of the provisions of this Agreement, the provisions of this Agreement
shall control. If any requirements relating to the duties or obligations of the
Escrow Holder are unacceptable to the Escrow Holder, or if the Escrow Holder
requires additional instructions, the parties agree to make any deletions,
substi tutions and additions as counsel for Buyer and Seller shall mutually
approve and which do not materially alter the terms of this Agreement. Any
supplemental instructions shall be signed only as an accommodation to Escrow
Holder and shall not be deemed to modify or amend the rights of Buyer and
Seller, as between Buyer and Seller, unless the supplemental instructions
expressly so provide.

                  7.4 PRORATIONS. It is the intent of the parties that Seller
shall bear all expenses of ownership and operation of the Property and shall
receive all income therefrom applicable or relating to the period ending at
11:59 p.m. on the day preceding the Close of Escrow, and Buyer shall bear all
such expenses and receive all such income applicable or relating to the period
beginning thereafter (such income and expenses being those defined as such by
generally accepted accounting principals, consistently applied). Rentals,
revenues, and other income from the Property, and taxes, assessments,
improvement bonds and any and all other expenses affecting the Property shall be
prorated as of 11:59 p.m. on the day preceding the Close of Escrow. For purposes
of calculating prorations, Buyer shall be deemed to be in title of the Property,
and therefore entitled to the income and responsible for the expenses, for the
entire day upon which the Close of Escrow occurs. Buyer shall be responsible for
obtaining a new policy of casualty and/or liability insurance as of the Close of
Escrow. All prorations shall be made in accordance with customary practice in
the county in which the Property is located, except as expressly provided
herein. Such prorations, if and to the extent known and agreed upon as of the
Close of Escrow, shall be paid through Escrow by Buyer to Seller (if the
prorations result in a net credit to the Seller) or by Seller to Buyer (if the
prorations result in a net credit to the Buyer). Any items of income or expense
or other prorations not determined or not agreed upon or later shown to have
been incorrect as of the Close of Escrow shall be paid by Buyer to Seller, or by
Seller to Buyer, as the case may be, in cash, as soon as practicable following
the determination of such amounts provided, that no adjustment will be required
after the expiration of fifteen (15) months after the Close of Escrow, except
for any tax refunds (including, without limitation, any tax refunds resulting
from any Tax Protest Proceedings (defined beow)) with respect to which the
foregoing obligations of Buyer and Seller shall continue to apply. Without
limiting the generality of the foregoing:
<PAGE>

                             (a)   Rent.  All rents, fees and charges,
including, without limitation, payments of minimum or base rents, fixed monthly
rents, additional rents, retroactive rents, operating cost pass-through, rent
escalations, percentage rents, sign revenues, other receipts, operating expenses
of the Property, tenant expenses, taxes, assessments, electricity and other
utilities, common area maintenance and services, other escalation charges and
other amounts due Seller pursuant to the Leases or due Seller with respect to
the Property generally or otherwise payable under the Leases (all of the
foregoing may hereinafter be collectively referred to as "Rents") shall be
prorated as of the Close of Escrow. Subject to the provisions below, Rents
delinquent at the Close of Escrow shall be prorated to the Close of Escrow when
collected. Rents collected within twelve (12) months after the Close of Escrow
shall be deemed to apply (after deduction of costs for collections) first to
Rents currently or past due and payable to Buyer for the period after Close of
Escrow from tenants making such payments, and second to Rents which are due and
payable to Seller for the period prior to Close of Escrow from tenants making
such payments. Buyer shall at all times for twelve (12) months after the Close
of Escrow, continue to invoice tenants for all Rents which are delinquent or
unpaid as of the Close of Escrow or which otherwise belong to Seller pursuant to
this Agreement. Rents collected by Buyer after the Close of Escrow, to which
Seller is entitled under this Paragraph, shall be promptly paid over, in cash,
to Seller after deduction of any reasonably incurred collection costs but
otherwise without offset or deduction. Seller reserves the rights to all
delinquent or past due Rents owing to Seller for periods prior to the Close of
Escrow and Buyer acknowledges that such Rents are the property of Seller and are
hereby specifically reserved by Seller. Such reservation by Seller and the
foregoing rights of Seller shall survive the Close of Escrow, the recordation of
the Deed and the execution, delivery and recordation of the Lease Assignment
(defined below) and shall supersede any provision herein or in the Lease
Assignment tothe contrary. Seller may proceed to institute any and all legal
proceedings to which it is legally entitled to recover such amounts from such
tenants, except that Seller shall not be permitted to institute legal
proceedings for unlawful detainer against such tenants or to seek to terminate
their Leases.

                             (b)   Omitted.
<PAGE>

                             (c)   Expenses.  Subject to Paragraph 7.4(d) and
7.4(g) hereof, all operating expenses of the Property shall be prorated as of
the Close of Escrow. As used in this Agreement, the term "operating expenses of
the Property" shall include, without limitation, any and all: (i) utility
charges and deposits as shown on the last ascertainable bills (if current bills
are not available) if and to the extent the utility meters are not read as of
the Close of Escrow; (ii) charges and deposits under any Contracts; (iii)
operating cost pass-through, elevator maintenance costs and expenses, common
area maintenance costs and expenses, non-common area maintenance costs and
expenses, taxes (including, without limitation, real estate taxes and rental
taxes), (iv) other expenses incurred in operating the Property that a property
owner customarily pays ; and (v) any other costs incurred in the ordinary course
of the 0 operation of the Property. Buyer shall pay all such expenses accruing
on the Close of Escrow and thereafter. To the extent practicable, Seller and
Buyer shall obtain billings and meter readings as of the Close of Escrow to aid
in such prorations. Buyer shall not be responsible for any management fees
attributable to the Property which expenses accrued and were payable prior to
the Closing Date, nor shall Buyer by responsible for any cancellation or
termination fees contained in any management agreement of Seller affecting the
Property unless expressly assumed in writing by Buyer.

                             (d)   Estimated Payments.  To the extent that any
additional rent (including, without limitation, estimated payments for operating
expenses and/or real estate taxes) (collectively, "Expenses") is paid by tenants
under the Leases based on an estimated payment basis (monthly, quarterly, or
otherwise) for which a future reconciliation of actual Expenses to estimated
payments is required to be performed at the end of a reconciliation period,
Buyer and Seller shall make an adjustment at the Close of Escrow for the
applicable reconciliation period (or periods, if the Leases do not have a common
reconciliation period) based on a comparison of the actual Expenses to the
estimated payments (to the extent such estimated payments were actually received
by Seller) at the Close of Escrow. If, as of the Close of Escrow, Seller has
received rent payments for Expenses in excess of the amount that tenants will be
required to pay, based on the actual Expenses as of the Close of Escrow, Buyer
shall receive a credit at Closing in the amount of such excess. If, as of the
Close of Escrow, Seller has received rent payments for Expenses that are less
than the amount that tenants will be required to pay based on the actual
Expenses as of the Close of Escrow, Buyer shall include such deficient amount in
its billings to such tenants for reconciliation of the estimated
<PAGE>

payments for such Expenses and so long as Buyer, as landlord, is current in
payments from such tenants, shall pay such deficient amount to Seller promptly
following Buyer's receipt of such amount from such tenants.

                             (e)   Leasing Costs.  Subject to the terms of
Paragraph 12 with regard to Approved New Lease Transactions, in the event that
any Lease requires, at any time after the Close of Escrow, the construction of
tenant fixtures or improvements or the payment of leasing or brokerage
commissions at the expense of landlord, or requires any other expenditure of
money or the incurring of any other obligation or the performance of any
covenant by the landlord under such Lease, Buyer, by electing to cause the Close
of Escrow to occur, hereby agrees to assume any and all such obligations.

                             (f)   Security Deposits.  Buyer shall receive a
credit at Closing for each of the security deposits listed on the
attached Exhibit "K".

                             (g)   Owner Deposits.  Seller shall receive a
credit at Closing for all bonds, deposits, letters of credit, set aside letters
or other similar items, if any, that are outstanding with respect to the
Property that have been provided by Seller or any of its affiliates to any
governmental agency, public utility, or similar entity (collectively, "Owner
Deposits") to the extent assigned and assignable to Buyer. Otherwise, Buyer
shall replace all Owner Deposits based upon reasonable proof as to the amount of
the deposit. To the extent that any funds are released as result of the
termination or replacement of the Owner Deposits for which Seller did not get a
credit, such funds shall be delivered to Seller immediately upon their receipt.
Buyer shall reasonably cooperate with Seller in any efforts to obtain the
release of Seller's Owner Deposits (provided that Seller shall reimburse Buyer
for any costs incurred for such cooperation other than the amount of the Owner
Deposits to be replaced).

                             (h)   Tax Protests.  If Seller has engaged
consultants for the purpose of protesting the amount of taxes or the assessed
valuation for certain tax periods for the Property ("Protest Proceedings") any
refunds or proceeds will be apportioned as described below. Any refunds or
proceeds (including interest thereon) on account of a favorable determination,
after deduction of costs and expenses incurred for such Protest Proceedings and
payment of any reimbursements owing to tenants, shall be: (i) the property of
Seller to the extent such refunds or proceeds were for taxes applicable to a
period prior to the Closing Date, (ii) prorated between Buyer and Seller
<PAGE>

for taxes paid for a period during which the Closing Date occurred, and (iii)
the Property of Buyer for taxes paid by Buyer for a period after the Closing
Date. Seller shall have the obligation to refund to any tenants pursuant to the
Leases, any portion of such refund paid to it which may be owing to such
tenants, which payment shall be paid to Buyer within fifteen (15) days of
delivery to Seller by Buyer of written confirmation of such tenants' entitlement
to such refunds. Buyer shall have the obligation to refund to tenants such
refund, any portion of such refund paid to it which may be owing to such
tenants. Seller and Buyer agree to notify the other in writing of any receipt of
a tax refund within ten (10) business days of receipt of such refund. To the
extent either party obtains a refund, a portion of which is owed to the other
party, the receiving party shall deliver the refund to the other party within
fifteen (15) days of its receipt. No Protest Proceedings are currently in
process.

                             (i)   All prorations shall be made on the basis
of actual days in the month and a three hundred sixty-five (365) day year. The
obligations of Buyer and Seller under this Paragraph 7.4 shall survive the Close
of Escrow and the delivery and recordation of the Deed and the consummation of
the transactions contemplated herein.

                             (j)   Post-Closing Access.  After the Closing,
Seller, or any representative of Seller, shall for a period of one (1) year
after the Closing have the right to inspect the books and records of the
Property to verify that Buyer is remitting to Seller all amounts to be remitted
to Seller according to the terms of this Agreement and for any other purpose
related to Seller's prior ownership of the Property.

                  7.5 PAYMENT OF COSTS. Seller shall pay: (i) one-half of the
Escrow Fee, (ii) the base premium charges for a standard owner's title policy
which total fee is $57,000.00 ("Standard Premium") and (iii) the cost of
preparing the Deed. Buyer shall pay: (i) all title and title insurance costs and
premiums in excess of the Standard Premium (including, without limitation, the
cost of ALTA or any other extended coverage, any endorsements, and any survey
costs), (ii) one-half of the Escrow costs and fees; (iii) all costs relating to
financing the transaction; (iv) all recording fees for the Deed, deeds of trust
and other financing documentation; (v) all city, county, and state transfer,
documentary and excise fees and taxes; (vi) all costs arising from its due
diligence efforts, including, without limitation, any cost to update existing or
obtain new environmental studies, engineering reports or surveys; and (vii) all

                  15.7 NO WAIVER. A waiver by either party of a breach of any of
the covenants, conditions or obligations under this Agreement to be performed by

or to this Agreement, in order to become effective, shall be made in writing and

                  15.10 INTEGRATION OF PRIOR AGREEMENTS AND UNDERSTANDINGS. This

Agreement, and are of no force or effect, in whole or in part.

                  15.11 NOT AN OFFER. Seller's delivery of unsigned copies of
this Agreement is solely for the purposes of review by Buyer, and neither the
delivery nor any prior communications between Buyer and Seller, whether oral or
written, shall in any way be construed as an offer by Seller, nor in any way
imply that
<PAGE>

Seller is under any obligation to enter the transaction which is the subject of
this Agreement. The signing of this Agreement by Buyer constitutes an offer
which shall not be deemed accepted by Seller unless and until Seller has signed
this Agreement and delivered a duplicate original to Buyer.

done under this Agreement is computed by excluding the first day (such as the
Effective Date), and including the last day, unless the last day is a holiday or
Saturday or Sunday, and then that day is also excluded. All references to time
shall be deemed to refer to Eastern Standard Time.

                  15.17 JOINT AND SEVERAL LIABILITY. If Buyer is composed of
more than one individual or entity, all obligations and liabilities of Buyer
under this Agreement shall be joint and several as to each of those individuals
or entities who compose Buyer.

                  15.18      BUYER'S WORK PRODUCT CONCERNING THE PROPERTY.  If
for any reason Buyer fails to purchase the Property, and as a
condition to the return of the Deposit to Buyer (if Buyer is so
entitled), Buyer shall promptly deliver to Seller, at no cost or
expense to Seller, all test results, studies, plans, or other
materials prepared by Buyer, or its agents, employees or
contractors, relating to the physical, environmental,
engineering, or survey condition of the Property ("Work
Product"), except to the extent protected by the attorney-client
or attorney work product privileges.  Also, Buyer will not be
required to deliver any Work Product to Seller, the delivery of

written agreement with the preparer of the Work Product provided,
<PAGE>

that Buyer shall use all reasonable efforts to enter into agreements with
preparers of Work Product which do not prohibit the delivery of the Work Product
to Seller. Following delivery, Seller may use this Work Product for any purpose.

Agreement, including, without limitation, the Broker.

                  15.20 SURVIVAL OF COVENANTS. Except as otherwise limited
pursuant to the terms of the Agreement, the covenants, agreements, indemnitees,
representations and warranties of Buyer and Seller shall survive the Close of
Escrow and shall not merge into the Deed.

3.2.

                      (a)   Purchaser shall have a right to enter upon the

permit any mechanic liens, materialmen's liens or other liens to be filed
against the Property as a result of its Due Diligence. Subject to the provisions

not constitute a waiver by Purchaser of any representation, warranty, covenant
or agreement of Seller which might, or should have been disclosed by such
inspection. In addition, Seller shall cooperate with Purchaser in facilitating
its Due Diligence inquiry.

                      (b)   Purchaser shall have through the last day of
the Due Diligence Period in which to conduct its Due Diligence and, in
Purchaser's sole discretion, to determine whether the Property is acceptable to
Purchaser. If during the Due Diligence Period, Purchaser becomes aware of any
problem or defect in the Property or any other aspect of the Property which
Purchaser determines makes the Property unsuitable to Purchaser or if Purchaser
otherwise determines for any reason not to acquire the Property, Purchaser may
terminate this Agreement by giving written notice of termination to Seller on or
before 5:00 p.m. (C.S.T.) on the last day of the Due Diligence Period. If
Purchaser does not timely give notice of termination as aforesaid, Purchaser
shall be deemed to have accepted the Property and this Agreement shall continue
in full force and effect. In the event of such termination, the Earnest Money
less Seller Retention shall be returned to Purchaser and neither party shall
have any further obligations to the other party hereunder,
<PAGE>

except for the Surviving Obligations.

                      (c)   Purchaser shall, at least thirty-one (31) days
prior to the Closing Date, notify Seller in writing requesting termination of
any or all of the Service Contracts, which are noted on Schedule 2 as being
terminable upon thirty (30) days notice, that Purchaser does not elect to
assume. If Purchaser does not timely give notice requesting termination of a
Service Contract, Purchaser shall be deemed to have accepted the assumption of
such Service Contract. Purchaser shall assume all other Service Contracts.
Seller shall terminate effective as of the Closing Date at its sole cost all
Service Contracts which Purchaser elects not to assume in accordance with the
terms hereof.

                      (d)   Purchaser shall have the right to conduct, at
its sole cost and expense, any inspections, studies or tests including, without
limitation, environmental inspections, studies and tests, that Purchaser deems
appropriate in determining the condition of the Property, provided, however,
Purchaser is not permitted to perform any intrusive testing, including, without
limitation, a Phase II environmental assessment or boring, without (i)
submitting to Seller the scope and inspections for such testing; and (ii)
obtaining the prior written consent of Seller which consent shall not be
unreasonably withheld except that Seller may withhold consent to borings into
the ground water in its sole and absolute discretion.

                      (e)   Purchaser agrees and covenants with Seller not
to disclose to any third party (other than lenders, accountants, attorneys and
other professionals and consultants in connection with the transaction
contemplated herein) without Seller's prior written consent, unless Purchaser is
obligated by law, or rule of any stock exchange to make such disclosure, any of
the reports or any other documentation or information obtained by Purchaser
which relates to the Property or Seller in any way, all of which shall be used
by Purchaser and its agents solely in connection with the transaction
contemplated hereby. In the event that this Agreement is terminated, Purchaser
agrees that all such information will be held in strict confidence.

                      (f)   Purchaser agrees to indemnify, defend and hold
Seller and its partners, trustees, beneficiaries, shareholders, members,
managers, advisors and other agents and their respective partners, trustees,
beneficiaries, employees, officers, directors and shareholders (the "Indemnified
Parties") harmless from and against any and all claims, losses, damages, costs
and expenses (including, without limitation, reasonable attorneys' fees and
<PAGE>

court costs) suffered or incurred by any of the Indemnified Parties as a result
of or in connection with any activities of Purchaser (including activities of
any of Purchaser's employees, consultants, contractors or other agents) relating
to the Property, including, without limitation, mechanics' liens, damage to the
Property, injury to persons or property resulting from such activities in
connection therewith, and in the event that the Property is disturbed or altered
in any way as a result of such activities. Purchaser shall promptly restore the
Property to substantially its condition existing prior to the commencement of
such activities which disturb or alter the Property. Notwithstanding any
contrary provision in this Section 3.2(f), in no event shall Purchaser have any
obligation under this Section 3.2(f) if it discovers any environmental
contamination at the Property in connection with its Due Diligence Activities.
Furthermore, Purchaser agrees to maintain and cause any of its representatives
or agents conducting any Due Diligence to maintain and have in effect commercial
general liability insurance with (i) all occurrence coverage, (ii) waiver of
subrogation, and (iii) limits of not less than One Million and 00/100 Dollars
($1,000,000.00) for personal injury, including bodily injury and death, and
property damage. Such insurance shall name the Seller, Heitman Capital
Management Corporation ("HCMC") and Heitman Properties of Texas Ltd. and their
respective partners, trustees, beneficiaries, shareholders, members, employees,
officers and directors as additional insured parties. Purchaser shall deliver to
Seller a copy of the certificate of insurance effectuating the insurance
required hereunder prior to the commencement of such activities which
certificate shall provide that such insurance shall not be terminated or
modified without at least thirty (30) days' prior written notice to Seller.

                      (g)   Purchaser acknowledges and agrees that it
shall have no right to review or inspect any of the following: (i) internal
memoranda, correspondence, analyses, documents or reports prepared by or for
Seller or an affiliate of Seller in connection with (A) this Agreement, (B) the
transaction contemplated by this Agreement, (C) the acquisition of the Property
by Seller (other than environmental, engineering, soils and similar reports) or
(D) any prior or current contemplated reorganization of Seller and certain
affiliated funds, (ii) communications between Seller and HCMC or any of its
affiliates, and (iii) appraisals, assessments or other valuations of the
Property in the possession of Seller or HCMC.

                      (h)   Section 3.2(e) shall survive termination of
this Agreement, but not Closing, and Section 3.2(f) and such
<PAGE>

other designated provisions in this Agreement shall survive Closing or any
termination of this Agreement as specified herein (collectively, the "Surviving
Obligations").

         3. Title and Survey. Seller shall, at Seller's sole cost and expense,
obtain and deliver to Purchaser for Purchaser's review a commitment for a
standard Texas owner's policy of title insurance along with a copy of each
instrument listed as an exception thereon (the "Title Commitment") on the Real
Property issued by the Title Company and the Existing Survey. During the Due
Diligence Period, Purchaser shall have the right to request, at its sole cost
and expense, any desired endorsements to the final title policy which are
available, if any, as well as deletion of the survey exception. Purchaser may
elect to receive an update to the Existing Survey (the "Updated Survey") by
notifying Seller of such election in writing within five (5) days after
Purchaser's receipt of the Existing Survey. If Purchaser so elects, Seller
shall, at Purchaser's sole cost and expense, obtain and deliver to Purchaser for
Purchaser's review the Updated Survey. The Updated Survey shall: (i) be made in
accordance with the specifications listed on Exhibit C attached hereto, and (ii)
contain a certification in the form set forth on Exhibit D attached hereto.
Purchaser shall have until the date which is fifteen (15) days after receipt of
the Title Commitment and Existing Survey (such date being referred to as the
"Title Review Date") for examination of Title Commitment and Existing Survey and
the making of any objections thereto, said objections to be made in writing and
delivered to Seller on or before 5:00 p.m. (C.S.T.) on the Title Review Date. If
Purchaser shall fail to make any objections on or before the Title Review Date,
Purchaser shall be deemed to have accepted all exceptions to the Title
Commitment and the form and substance of the Existing Survey and all matters
shown thereon; all such exceptions and matters and any exceptions or matters
caused by or through Purchaser shall be included in the term "Permitted
Exceptions" as used herein. In the event Purchaser elects to receive the Updated
Survey, then Purchaser shall have until the expiration of the Due Diligence
Period for examination of the Updated Survey and the making of objections only
to matters shown thereon that were not shown on the Existing Survey, such
objections to be made in writing and delivered to Seller on or before the
expiration of the Due Diligence Period. If Purchaser shall fail to make any such
objections to the Updated Survey on or before the expiration of the Due
Diligence Period, Purchaser shall be deemed to have accepted the form and
substance of the Updated Survey and all matters shown thereon; all such
exceptions and matters and any exceptions or matters caused by or through the
Purchaser shall be included as Permitted Exceptions. If any objections to (i)
the
<PAGE>

Title Commitment or Existing Survey are made within the Title Review Period, or
(ii) the Updated Survey with respect to matters not shown on the Existing Survey
are made before the expiration of the Due Diligence Period, then Seller shall
have the right, but not the obligation, to cure (by removal, endorsement or
otherwise) such objections on or before the Closing Date; provided, however,
Seller shall be obligated (a) to cause to be released on or before the Closing
Date any monetary liens or security interests created by, through or under
Seller and any ad valorem taxes due and payable on the Property, and (b) to
cause to be released, on or before Closing Date, liens created by, through or
under third parties but in no event will Seller be obligated to expend or incur
any expense or liability for such cure for liens or security interests created
by, through or under third parties in excess of an aggregate of Two Hundred
Thousand Dollars ($200,000), and failure to do so shall be a default for which
the provisions of Section 17(a) shall apply. If the objections which the Seller
has the right but not the obligation to cure are not cured by Seller by the
scheduled Closing Date, then Purchaser may as its only option, elect to either:
(i) waive such objection and consummate the transaction contemplated by this
Agreement; or (ii) terminate this Agreement, in which event the Earnest Money
less Seller Retention shall be returned to Purchaser and neither party shall
have any further obligations to the other party except for the Surviving
Obligations.

         4. Tenant Estoppels. Seller shall deliver to Purchaser, no later than
five (5) days prior to the Closing Date, estoppel certificates, in the form of
Exhibit E attached hereto or in the form of estoppel required under such
tenant's lease, from tenants leasing at least ninety percent (90%) of the square
footage of the Property currently leased, which shall include all tenants
leasing 4,000 square feet or more of the Property, and such estoppels shall not
disclose any facts objectionable to Purchaser in its reasonable opinion.

mark-up of the Title Commitment, extending the effective date to the Closing
Date, insuring Purchaser as owner of the Real Property, and removing all

         4. Permitted Termination. So long as a party is not in default
hereunder, if any condition to such party's obligation to proceed with the
Closing hereunder has not been satisfied or waived as of the Closing Date or
such earlier date as provided herein, such party may, in its sole discretion,
terminate this Agreement by delivering written notice to the other party before
the Closing Date (in which event the Earnest Money, less Seller Retention, shall
be returned to Purchaser), or elect to close, notwithstanding the
non-satisfaction of such condition, in which event such party shall be deemed to
have waived any such condition.

L. Prorations.  All items of income and expense shall be paid,
prorated or adjusted as of the close of business on the day prior
to the Closing Date (the "Proration Date") in the manner
hereinafter set forth:

         1. Purchaser shall be credited with (i) the amount of (A) all rents and
(B) all expense contributions, real estate tax contributions, and other
reimbursements from tenants ("Tenant Contributions") received by Seller and
attributable to any month commencing after the Closing Date and (ii) all
unapplied cash security deposits held by Seller and which were made by tenants
under all leases of the Real Property in effect as of the Closing Date.

         2. All rents and Tenant Contributions for the month of Closing shall be
prorated between Purchaser and Seller based upon their respective days of
ownership for such month in which the Closing occurs. Neither Purchaser nor
Seller shall receive credit at Closing for any payments of rental obligations
due but
<PAGE>

not paid as of the Proration Date. At the time of each of the final calculations
and collections from tenants of Tenant Contributions for 1998, whether in the
nature of a reconciliation payment or full payment, in arrears, there shall be a
reproration between Purchaser and Seller as to the Tenant Contributions. Such
reproration shall not be made on the basis of a per diem method of allocation,
but shall instead be apportioned between Seller and Purchaser on the basis of
the relative share of actual expenses in question incurred by Seller and
Purchaser during the lease year in question. Seller covenants to provide
Purchaser with any information necessary to finalize such calculation. Purchaser
covenants to bill tenants for amounts due from tenants attributable to periods
prior to Closing (including, without limitation, 1997 Tenant Contributions due
from Tenants based on reconciliation calculations furnished to Purchaser by
Seller) and diligently pursue collections from tenants and, as collected, to
timely deliver to Seller amounts due Seller, provided, however, Purchaser shall
not be required to sue any tenant for amounts due from such tenant.

         3. Intentionally Omitted.

         4. Any amounts received from tenants after Closing shall be applied on
a tenant by tenant basis in the following order: (i) first on account of any
amount due Purchaser from such tenant(s); (ii) next, on account of any amount
due Seller from such tenant(s) for the period up to and including the Proration
Date and (iii) finally, any balance then remaining to Purchaser. Seller retains
the right to pursue its remedies against tenants after Closing for any
delinquent payments or other amounts owed to Seller, except for actions or
proceedings affecting possession or landlord liens. However, Seller will not
exercise any such rights or remedies unless such delinquent rents have not been
collected by Purchaser and paid to Seller within three (3) months after the
Closing Date. Any money due to Seller shall be remitted to Seller, less a
proportionate share of any reasonable attorneys' fees and third party costs and
expenses in connection with collection thereof, within five days after the end
of the month in which it was received by Purchaser.

         5. Operating expenses, including, without limitation, payments under
Service Contracts to be assigned to Purchaser, permits, licenses, membership
dues, and any other prepaid expenses, shall be prorated between Purchaser and
Seller based upon the actual days of their respective ownership of the Property
utilizing the actual expenses or reasonable estimates.

         6. Real estate taxes shall be prorated between Seller and
<PAGE>

Purchaser based upon the actual days of ownership of the parties for the year in
which Closing occurs utilizing the most recent ascertainable tax bill(s). Seller
and Purchaser agree to reprorate said real estate taxes upon Purchaser's receipt
of the actual tax bill for the tax year in question, if any. Seller reserves the
right (a) to meet with governmental officials and to contest any reassessment
governing or affecting Seller's obligations under this Section, and (b) to
contest any assessment of the Property or any portion thereof and to attempt to
obtain a refund for any taxes previously paid. Seller shall retain all rights
with respect to any refund of taxes applicable to any period prior to the
Closing Date.

         7. Except for utilities billed directly to Tenants, utilities shall be
prorated as of the Proration Date based upon either meter readings on the
Proration Date or the prior month's actual invoices. Seller shall be credited
with any unapplied utility deposit in effect as of the Closing Date to the
extent such deposit is assignable.

         8. Purchaser shall be responsible for and pay for both: (a) the cost of
all tenant improvements, concessions, inducements and abatements, and (b) all
leasing commissions due and payable as a result of leases made pursuant to (i)
Proposals listed on Schedule 4 attached hereto, (ii) any lease entered into
after the date hereof through the date which is five (5) days prior to the
expiration of the Due Diligence Period, and (iii) any Proposal which Purchaser
approved, or is deemed to have approved as provided in Section 15. Purchaser
shall receive a credit on the Closing Date equal to all leasing commissions due
to leasing or other agents for the current remaining term of each Lease listed
or required to be listed on Schedule 1 (determined without regard to any
unexercised termination or cancellation right), discounted to present value
using reasonable discount rates; provided, however, Seller shall have no
liability for any deferred commission due to the Emerson Groups for the lease to
Globeset, Inc. in the aggregate amount of $31,040.36. Purchaser shall assume, in
writing, the obligation to pay any such leasing commissions due thereunder after
the Closing Date up to the amount of such credit (without discount). Purchaser
shall promptly return to Seller any such commission (without discount) that, due
to later events, does not become due and payable. At Closing, Purchaser shall
assume leasing commissions for renewals or expansions under any Lease identified
in Schedule 1 as a result of the exercise of such right after the effective date
of this Agreement. If by Closing Seller has not completed and paid in full for
all tenant improvement expenses, tenant allowances, concessions, inducements and
abatements which are the obligation
<PAGE>

of landlord under the Leases listed or required to be listed on Schedule 1 but
excluding obligations on which Seller has not commenced work and which are not
required to be completed prior to Closing ("TI Obligations"), then such costs as
reasonably agreed by Purchaser and Seller shall be withheld from the Purchase
Price at Closing and Purchaser shall be responsible for completing and paying
such TI Obligations. Anything in the prior sentence to the contrary
notwithstanding, the obligations for work or allowance under the New York Life
Insurance Company lease shall be a TI Obligation. Any funds withheld shall be
used by Purchaser to pay the landlord's share of such tenant improvement and
allowances. If there are any funds remaining after payment of such TI
Obligations, such excess shall be paid by Purchaser to Seller; but if the amount
withheld is insufficient for the purpose, Seller shall reimburse Purchaser for
such deficiency on demand.

         9. All insurance policies and property management agreements shall be
terminated as of the Closing Date and there shall be no proration with respect
to these items.

All other items which are customarily prorated in transactions similar to the
transaction contemplated hereby and which were not heretofore dealt with, will
be prorated as of the Proration Date. In the event any prorations or
computations made under this Section are based on estimates or prove to be
incorrect, then either party shall be entitled to an adjustment to correct the
same, provided that it makes written demand on the party from whom it is
entitled to such adjustment within one hundred and twenty days after the end of
the current calendar year. Purchaser shall indemnify and hold Seller harmless
from and against any and all claims for which Purchaser received credits
pursuant to this Section 5. The indemnity set forth in the immediately preceding
sentence and the covenants contained in this Section 5 shall survive Closing and
constitute Surviving Obligations.

U. Fire or Other Casualty; Condemnation.

         1. If the Property or any part thereof is damaged by fire or other
casualty prior to the Closing Date which would cost in excess of $500,000.00 to
repair (as determined by an insurance adjuster selected by the insurance
carriers), or which can be the basis for any tenant to terminate any Leases
which, individually or in the aggregate, is for more than 20,000 square feet of
net rentable area, Purchaser may terminate this Agreement by written notice to
Seller given on or before the earlier of (i) twenty (20) days following receipt
of notice from Seller of such casualty or (ii) the Closing Date. In the event of
such termination, this Agreement shall be of no further force and effect and,
except for the Surviving Obligations, neither party shall thereafter have any
further obligation under this Agreement, and Seller shall direct the Title
Company to promptly return all Earnest Money to Purchaser. If Purchaser does not
have the right to or does not elect to terminate this Agreement, then the
Closing shall take place as herein provided without abatement of the Purchase
Price, and Seller shall assign and transfer to Purchaser on the Closing Date,
without warranty or recourse, all of Seller's right, title and interest to the
balance of insurance proceeds paid or payable to Seller on account of such fire
or casualty remaining after reimbursement to Seller for the total amount of all
costs and expenses incurred by Seller in connection therewith including but not
limited to making emergency repairs, securing the Property and complying with
applicable governmental requirements. Seller shall pay to Purchaser the amount
of the deductible of any of Seller's applicable insurance policies.

         2. If any material portion of the Property is taken in eminent domain
proceedings prior to Closing, Purchaser may terminate this Agreement by notice
to Seller given on or before the earlier of (i) twenty (20) days after such
taking or (ii) the Closing Date, and, in the event of such termination, this
Agreement shall be of no further force and effect and, except for the Surviving
Obligations, neither party shall thereafter have any further obligation under
this Agreement, and Seller shall direct the Title Company to promptly return all
Earnest Money to Purchaser. If Purchaser does not so elect to terminate or if
the taking is not material, then the Closing shall take place as herein provided
without abatement of the Purchase Price, and Seller shall deliver or assign to
Purchaser on the Closing Date, without warranty or recourse, all of Seller's
right, title and interest in and to all condemnation awards paid or payable to
Seller. As used in this Section 14.2, "material portion" means a part of the
Property which if taken in eminent domain proceedings
<PAGE>

would have an adverse effect on Purchaser's use or occupancy of
the Property.

V. Operations After Date of This Agreement. Seller covenants
and agrees with Purchaser that:

         (a) after the date hereof through the Closing, Seller will (except as
specifically provided to the contrary herein):

                  (i) Refrain from transferring any of the Property or creating
         on the Property any easements, liens, mortgages, encumbrances, or other
         interests which will survive Closing or permitting any changes to the
         zoning classification of the Land;

                  (ii) Refrain from entering into or amending any contracts, or
         other agreements (excluding leases) regarding the Property (other than
         contracts in the ordinary and usual course of business and which are
         cancelable by the owner of the Property without penalty within thirty
         (30) days after giving notice thereof);

                  (iii) Continue to operate, maintain, and repair the Property
         in a manner consistent with Seller's current practices;

                  (iv) Fully comply with the terms of the Leases;

                  (v) Refrain from offering the Property for sale or marketing
         the same or negotiating with respect to or entering into any other
         agreement for the sale of the Property;

                  (vi) Cancel any Lease without Purchaser's prior written
         consent (which shall not be unreasonably withheld);

                  (vii) Refrain from applying tenant security deposits without
         Purchaser's approval (which shall not be unreasonably withheld);

                  (viii) Maintain existing insurance coverage relating to the
         Property; and

                  (ix) Deliver to Purchaser not less than five (5) days prior to
         the expiration of the Due Diligence Period copies of all leases entered
         into after the date hereof through the date which is five (5) days
         prior to the expiration of the Due Diligence Period and copies of all
         Proposals (as defined
<PAGE>

         in Section 15(b) below) with respect to which no lease has been
         executed and which has not expired or been withdrawn, except as
         provided otherwise in Section 15(b) below.

         (b) after the date which is five (5) days prior to the expiration of
the Due Diligence Period through the Closing, Seller will (except as
specifically provided to the contrary herein) refrain from (i) amending any
Leases of any portion of the Property, or (ii) executing any new leases without
the prior written consent of Purchaser (which consent shall not be unreasonably
withheld). As used herein, "Proposal" shall mean a description of the economic
terms of any proposed lease or amendment along with any financial information on
the tenant in Seller's possession. Purchaser shall be deemed to have approved:
(x) all Proposals listed on Schedule 4 attached hereto; and (y) any Proposals
delivered to Purchaser after the date hereof through the date which is five (5)
days prior to the expiration of the Due Diligence Period. Seller shall have the
right to execute lease documents evidencing a Proposal approved or deemed
approved by Purchaser.

W. Assignment. Purchaser shall not assign this Agreement without Seller's prior
written consent which consent may be withheld for any reason or no reason;
provided, however, Purchaser may assign this Agreement to an affiliate of
Mack-Cali Realty Acquisition Corp., without the consent of Seller so long as
such Assignee complies with the requirements of the last sentence of this
Section 16. Subject to the previous sentence, this Agreement shall apply to,
inure to the benefit of and be binding upon and enforceable against the parties
hereto and their respective successors and assigns. Seller's consent to any such
assignment shall be conditioned upon Seller's receipt of the following not less
than five (5) business days prior to the Closing Date: (i) a duly executed
express assumption of all of the duties and obligations of Purchaser by the
proposed assignee in a form acceptable to Seller, and (ii) an ERISA certificate,
in the form attached hereto as Exhibit B and the content of which is
satisfactory to Seller.

X. Remedies.

         (a) IN THE EVENT THAT SELLER SHALL FAIL TO CONSUMMATE THIS AGREEMENT
AND SUCH FAILURE IS NOT A RESULT OF PURCHASER'S DEFAULT OR A TERMINATION OF THIS
AGREEMENT BY PURCHASER OR SELLER PURSUANT TO A RIGHT TO DO SO UNDER THE
PROVISIONS HEREOF, PURCHASER, SHALL ONLY BE ENTITLED TO SEEK AT ITS ELECTION,
EITHER: (i) THE REMEDY OF SPECIFIC PERFORMANCE, OR (ii) DAMAGES IN AN AMOUNT NOT
TO EXCEED $1,000,000.00 IN THE AGGREGATE FOR ALL
<PAGE>

RECOURSE OF PURCHASER UNDER THE PURCHASE DOCUMENTS (AS DEFINED IN SECTION 19
HEREOF) EXCEPT ARISING OUT OF SELLER'S OBLIGATIONS FOR REPRORATIONS AND UNDER
SECTION 15. IN NO EVENT SHALL SELLER BE LIABLE TO PURCHASER FOR ANY PUNITIVE,
SPECULATIVE OR CONSEQUENTIAL DAMAGES; PROVIDED, HOWEVER, IN THE CASE WHERE SUCH
FAILURE IS BASED UPON AN ACT WHICH IS NOT WITHIN SELLER'S CONTROL, PURCHASER, AS
ITS SOLE AND EXCLUSIVE REMEDY, MAY TERMINATE THIS AGREEMENT AND RECEIVE A REFUND
OF THE EARNEST MONEY LESS SELLER RETENTION. IN NO EVENT SHALL PURCHASER BE
ENTITLED TO RECORD A LIS PENDENS OR NOTICE OF PENDENCY OF ACTION AGAINST THE
PROPERTY FOR ANY REASON WHATSOEVER EXCEPT IF PURCHASER ELECTS THE REMEDY OF
SPECIFIC PERFORMANCE.

         (b) IN THE EVENT THAT PURCHASER SHOULD FAIL TO CONSUMMATE THIS
AGREEMENT FOR ANY REASON, EXCEPT SELLER'S DEFAULT OR THE TERMINATION OF THIS
AGREEMENT BY PURCHASER PURSUANT TO A RIGHT TO DO SO UNDER THE TERMS AND
PROVISIONS HEREOF, THEN SELLER, AS ITS SOLE AND EXCLUSIVE REMEDY MAY TERMINATE
THIS AGREEMENT BY NOTIFYING PURCHASER THEREOF AND RECEIVE OR RETAIN THE EARNEST
MONEY AS LIQUIDATED DAMAGES, PROVIDED THAT THIS PROVISION SHALL NOT LIMIT
SELLER'S RIGHTS TO RECEIVE REIMBURSEMENT FOR ATTORNEYS' FEES AND TO PURSUE AND
RECOVER ON A CLAIM WITH RESPECT TO ANY SURVIVING OBLIGATIONS. THE PARTIES AGREE
THAT SELLER WILL SUFFER DAMAGES IN THE EVENT OF PURCHASER'S DEFAULT ON ITS
OBLIGATIONS. ALTHOUGH THE AMOUNT OF SUCH DAMAGES IS DIFFICULT OR IMPOSSIBLE TO
DETERMINE, THE PARTIES AGREE THAT THE AMOUNT OF THE EARNEST MONEY IS A
REASONABLE ESTIMATE OF SELLER'S LOSS IN THE EVENT OF PURCHASER'S DEFAULT. THUS,
SELLER SHALL ACCEPT AND RETAIN THE EARNEST MONEY AS LIQUIDATED DAMAGES BUT NOT
AS A PENALTY. EXCEPT AS OTHERWISE SET FORTH IN THIS SECTION 17(b), SUCH
LIQUIDATED DAMAGES SHALL CONSTITUTE SELLER'S SOLE AND EXCLUSIVE REMEDY. IN THE
EVENT SELLER IS ENTITLED TO THE EARNEST MONEY AS LIQUIDATED DAMAGES AND TO THE
EXTENT SELLER HAS NOT ALREADY RECEIVED THE EARNEST MONEY, THE EARNEST MONEY
SHALL BE IMMEDIATELY PAID TO SELLER BY THE TITLE COMPANY UPON RECEIPT OF WRITTEN
NOTICE FROM SELLER THAT PURCHASER HAS DEFAULTED UNDER THIS AGREEMENT, AND
PURCHASER AGREES TO TAKE ALL SUCH ACTIONS AND EXECUTE AND DELIVER ALL SUCH
DOCUMENTS NECESSARY OR APPROPRIATE TO EFFECT SUCH PAYMENT.

         SELLER AND PURCHASER ACKNOWLEDGE THAT THEY HAVE READ AND UNDERSTAND THE
PROVISIONS OF THE FOREGOING LIQUIDATED DAMAGES PROVISION AND BY THEIR SIGNATURES
IMMEDIATELY BELOW AGREE TO BE BOUND BY ITS TERMS.

Y. Miscellaneous.

         1. Entire Agreement. This Agreement, together with the exhibits
attached hereto, constitute the entire agreement of the parties hereto regarding
the purchase and sale of the Property, and all prior agreements, understandings,
representations and statements, oral or written, are hereby merged herein. In
the event of a conflict between the terms of this Agreement and any prior
written agreements, the terms of this Agreement shall prevail. This Agreement
may only be amended or modified by an instrument in writing, signed by the party
intended to be bound thereby.

         2. Time. All parties hereto agree that time is of the essence in this
transaction. If the time for performance of any obligation hereunder shall fall
on a Saturday, Sunday or holiday (national, in the State of Illinois or in the
State of Texas) such that the transaction contemplated hereby can not be
performed, the time for performance shall be extended to the next such
succeeding day where performance is possible.

         3. Counterpart Execution.  This Agreement may be executed
in one or more counterparts, each of which shall be deemed an
original.

         4. Governing Law.  THIS AGREEMENT SHALL BE DEEMED TO BE A
CONTRACT MADE UNDER THE LAWS OF THE STATE OF TEXAS AND FOR ALL
PURPOSES  SHALL BE GOVERNED BY AND INTERPRETED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF TEXAS.

         5. Publicity. Seller and Purchaser hereby covenant and agree that, at
all times after the date of execution hereof and continuing after the Closing,
unless consented to in writing by the other party or unless required to be made
by law or rule of
<PAGE>

any stock exchange, no press release or other public disclosure concerning this
transaction shall be made, and each party agrees to use best efforts to prevent
disclosure of this transaction. The provisions of this Section 18.5 shall
constitute Surviving Obligations.

         6. Recordation. Purchaser shall not record this Agreement or a
memorandum or other notice thereof in any public office without the express
written consent of Seller. A breach by Purchaser of this covenant shall
constitute a material default by Purchaser under this Agreement.

         7. Benefit. This Agreement is for the benefit of Purchaser and Seller,
and except as provided in the indemnity granted by Purchaser under Paragraphs
3.2 and 8.7 with respect to the Indemnified Parties listed therein, no other
person or entity will be entitled to rely on this Agreement, receive any benefit
from it or enforce any provisions of it against Purchaser or Seller.

         8. Section Headings. The Section headings contained in this Agreement
are for convenience only and shall in no way enlarge or limit the scope or
meaning of the various and several Sections hereof.

         9. Further Assurances. Purchaser and Seller agree to execute all
documents and instruments reasonably required in order to consummate the
purchase and sale herein contemplated.

         10. Severability. If any portion of this Agreement is held to be
unenforceable by a court of competent jurisdiction, the remainder of this
Agreement shall remain in full force and effect.

         11. Waiver of Trial by Jury. Seller and Purchaser, to the extent they
may legally do so, hereby expressly waive any right to trial by jury of any
claim, demand, action, cause of action, or proceeding arising under or with
respect to this Agreement, or in any way connected with, or related to, or
incidental to, the dealings of the parties hereto with respect to this Agreement
or the transactions related hereto or thereto, in each case whether now existing
or hereafter arising, and irrespective of whether sounding in contract, tort, or
otherwise. To the extent they may legally do so, Seller and Purchaser hereby
agree that any such claim, demand, action, cause of action, or proceeding shall
be decided by a court trial without a jury and that any party hereto may file an
original counterpart or a copy of this Section with any court as written
evidence of the consent of the other party
<PAGE>

or parties hereto to waiver of its or their right to trial by
jury.

         12. Independent Counsel. Purchaser and Seller each acknowledge that:
(a) they have been represented by independent counsel in connection with this
Agreement; (b) they have executed this Agreement with the advice of such
counsel; and (c) this Agreement is the result of negotiations between the
parties hereto and the advice and assistance of their respective counsel. The
fact that this Agreement was prepared by Seller's counsel as a matter of
convenience shall have no import or significance. Any uncertainty or ambiguity
in this Agreement shall not be construed against Seller because Seller's counsel
prepared this Agreement in its final form.

         13. Governmental Approvals. Nothing contained in this Agreement shall
be construed as authorizing Purchaser to apply for a zoning change, variance,
subdivision maps, lot line adjustment, or other discretionary governmental act,
approval or permit with respect to the Property prior to the Closing, and
Purchaser agrees not to do so. Purchaser agrees not to submit any reports,
studies or other documents, including, without limitation, plans and
specifications, impact statements for water, sewage, drainage or traffic,
environmental review forms, or energy conservation checklists to any
governmental agency, or any amendment or modification to any such instruments or
documents prior to the Closing. Purchaser's obligation to purchase the Property
shall not be subject to or conditioned upon Purchaser's obtaining any variances,
zoning amendments, subdivision maps, lot line adjustment or other discretionary
governmental act, approval or permit.

         14. No Waiver. No covenant, term or condition of this Agreement other
than as expressly set forth herein shall be deemed to have been waived by Seller
or Purchaser unless such waiver is in writing and executed by Seller or
Purchaser, as the case may be.

         15. Discharge and Survival. The delivery of the Deed by Seller, and the
acceptance thereof by Purchaser shall be deemed to be the full performance and
discharge of every covenant and obligation on the part of Seller to be performed
hereunder except the Surviving Obligations. No action shall be commenced after
the Closing on any covenant or obligation except the Surviving Obligations.
Anything in this Section 18.15 to the contrary notwithstanding, if Seller
breached the obligations of Seller under Section 15, the action against Seller
for such breach shall survive Closing and be a Surviving Obligation.
<PAGE>

Z. Exculpation of Seller and Related Parties. Notwithstanding anything to the
contrary contained in this Agreement or in any exhibits attached hereto or in
any documents executed in connection herewith (collectively, including this
Agreement, said exhibits and any such document, the "Purchase Documents"), it is
expressly understood and agreed by and between the parties hereto that: (i) the
recourse of Purchaser or its successors or assigns against Seller with respect
to the alleged breach by or on the part of Seller of any representation,
warranty, covenant, undertaking, indemnity or agreement contained in any of the
Purchase Documents other than Seller's obligations hereunder for reprorations
and under Section 15 (collectively, "Seller's Undertakings") shall be limited to
an amount not to exceed $1,000,000.00 in the aggregate; and (ii) except as
provided in (i) above with respect to Seller, no personal liability or personal
responsibility of any sort with respect to any of Seller's Undertakings or any
alleged breach thereof is assumed by, or shall at any time be asserted or
enforceable against, Seller or HCMC, or against any of their respective
shareholders, directors, officers, employees, agents, constituent partners,
members, beneficiaries, trustees or representatives.

AA. Information and Audit Cooperation. At Purchaser's request, at any time
before Closing, and within one (1) year after Closing, Seller will provide to
Purchaser's designated independent auditor access to those books and records of
the Property which are in Seller's possession and not provided to Buyer at
Closing, and Seller shall provide to such auditor a representation letter
regarding the books and records of the Property, in substantially the form of
Exhibit "N", attached hereto and incorporated herein by reference, in connection
with the normal course of auditing the Property in accordance with generally
accepted auditing standards; provided, however, that Purchaser shall indemnify
and hold Seller harmless from any liability, damages, costs, expenses (including
reasonable attorneys' fees and expenses) incurred by Seller as a result of the
execution and delivery of any letter to Purchaser's auditor.

         IN WITNESS WHEREOF, the parties hereto have caused these presents to be
made as of the day and year first above stated.

                                                               SELLER:

To the Representatives named in Schedule 1 hereto of the 
  several Underwriters named in Schedule 2 hereto

Ladies and Gentlemen:

            Cali Realty Corporation, a Maryland corporation qualified as a real
estate investment trust (the "Company"), hereby confirms its agreement with the
several underwriters named in Schedule 2 hereto (the "Underwriters"), for whom
you have been duly authorized to act as representatives (in such capacities, the
"Representatives"), as set forth below. If you are the only Underwriters, all
references herein to the Representatives shall be deemed to be to the
Underwriters.

            1. Securities. Subject to the terms and conditions herein contained,
the Company proposes to issue and sell to the several Underwriters certain
securities of the Company identified in Schedule 1 hereto (the "Firm
Securities"). The Company also proposes to issue and sell to the several
Underwriters the additional securities identified in Schedule 1 if requested by
the Representatives as provided in Section 3 of this Agreement. Any and all
shares of such additional securities to be purchased by the several Underwriters
pursuant to such option are referred to herein as the "Option Securities," and
the Firm Securities and any Option Securities are collectively referred to
herein as the "Securities."

            2. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, each of the several Underwriters
that:

                  (a) The Company meets the requirements for use of Form S-3
under the Securities Act of 1933, as amended (the "Act"). A registration
statement (the file number of which is set forth in Schedule 1 hereto) on such
Form with respect to the Securities, including a basic prospectus, has been
filed by the Company with the Securities and Exchange Commission


                                        1
<PAGE>

(including the Registration Statement) shall be deemed to include any document
incorporated by reference therein that is filed with the Commission under the

when the Prospectus is otherwise amended or supplemented and on the Firm Closing
Date and any Option Closing Date (both as hereinafter defined), each of the
Prospectus and, if required to be filed pursuant to Rules 434(c)(2) and 424(b)
under the Act, the Integrated Prospectus, as amended or supplemented at any such
time, (i) contained or will contain all statements required to be stated therein
in accordance with, and complied or will comply in all material respects with
the requirements of, the Act and the Exchange Act and the respective rules and
regulations of the Commission thereunder and (ii) did not or will not include
any untrue statement of a material fact or omit to state any material fact

            3. Purchase, Sale and Delivery of the Securities.

                  (a) On the basis of the representations, warranties,
agreements and covenants herein contained and subject to the terms and
conditions herein set forth, the Company agrees to issue and sell to each of the
Underwriters, and each of the Underwriters, severally and not jointly, agrees to
purchase from the Company, at the purchase price specified in Schedule 1 hereto,
the number of Firm Securities set forth opposite the name of such Underwriter in
Schedule 2 hereto. One or more certificates in definitive form for the Firm
Securities that the several Underwriters have agreed to purchase hereunder, and
in such denomination or denominations and registered in such name or names as
the Representatives request upon notice to the Company at


                                       14
<PAGE>

least 48 hours prior to the Firm Closing Date, shall be delivered by or on
behalf of the Company to the Representatives for the respective accounts of the
Underwriters, against payment by or on behalf of the Underwriters of the
purchase price therefor to the Company in such funds as are specified in
Schedule 1 hereto. Such delivery of and payment for the Firm Securities shall be
made at the date, time and place identified in Schedule 1 hereto, or at such
other date, time or place as the Representatives and the Company may agree upon
or as the Representatives may determine pursuant to Section 8 hereof, such date
and time of delivery against payment being herein referred to as the "Firm
Closing Date". The Company will make such certificate or certificates for the
Firm Securities available for checking and packaging by the Representatives at
the offices in New York, New York of the Company's transfer agent or registrar
or warrant agent or of Prudential Securities Incorporated at least 24 hours
prior to the Firm Closing Date.

                  (b) For the purpose of covering any over-allotments in
connection with the distribution and sale of the Firm Securities as contemplated
by the Prospectus and any Integrated Prospectus, the Company hereby grants to
the several Underwriters an option to purchase, severally and not jointly, the
Option Securities. The purchase price to be paid for any Option Securities shall
be the same price per share as the price per share for the Firm Securities set
forth in Schedule 1 to this Agreement, plus, if the purchase and sale of any
Option Securities takes place after the Firm Closing Date and after the Firm
Securities are trading "ex-dividend", an amount equal to the dividends payable
on such Option Securities. The option granted hereby may be exercised as to all
or any part of the Option Securities from time to time within thirty days after
the date of the Prospectus or any Integrated Prospectus (or, if such 30th day
shall be a Saturday or Sunday or a holiday, on the next business day thereafter
when the New York Stock Exchange is open for trading). The Underwriters shall
not be under any obligation to purchase any of the Option Securities prior to
the exercise of such option. The Representatives may from time to time exercise
the option granted hereby by giving notice in writing or by telephone (confirmed
in writing) to the Company setting forth the aggregate number of Option
Securities as to which the several Underwriters are then exercising the option
and the date and time for delivery of and payment for such Option Securities.
Any such date of delivery shall be determined by the Representatives but shall
not be earlier than two business days or later than five business days after
such exercise of the option and, in any event, shall not be earlier than the
Firm Closing Date. The time and date set forth in such notice, or such other
time on such other date as the Representatives and the Company may agree upon or
as the Representatives may determine pursuant to Section 9 hereof, is herein
called the "Option Closing Date" with respect to such Option Securities. Upon
exercise of the option as provided herein, the Company shall become obligated to
sell to each of the several Underwriters, and, subject to the terms and
conditions herein set forth, each of the Underwriters (severally and not
jointly) shall become obligated to purchase from the Company the same percentage
of the total number of the Option Securities as 


                                       15
<PAGE>

to which the several Underwriters are then exercising the option as such
Underwriter is obligated to purchase of the aggregate number of Firm Securities,
as adjusted by the Representatives in such manner as they deem advisable to
avoid fractional shares. If the option is exercised as to all or any portion of
the Option Securities, one or more certificates in definitive form for such
Option Securities, and payment therefor, shall be delivered on the related
Option Closing Date in the manner, and upon the terms and conditions, set forth
in paragraph (a) of this Section 3 and Schedule 1 to this Agreement, except that
reference therein to the Firm Securities and the Firm Closing Date shall be
deemed, for purposes of this paragraph (b), to refer to such Option Securities
and Option Closing Date, respectively.

                  (c) It is understood that any of you, individually and not as
one of the Representatives, may (but shall not be obligated to) make payment on
behalf of any Underwriter or Underwriters for any of the Securities to be
purchased by such Underwriter or Underwriters. No such payment shall relieve
such Underwriter or Underwriters from any of its or their obligations hereunder.

            4. Covenants of the Company. The Company covenants and agrees with
each of the Underwriters that:

                  (a) The Company will file the Prospectus or any Term Sheet
that constitutes a part thereof, any Integrated Prospectus or the Prospectus
Supplement, as the case may be, and any amendment or supplement thereto with the
Commission in the manner and within the time period required by Rules 434 and
424(b) under the Act. During any time when a prospectus relating to the
Securities is required to be delivered under the Act, the Company (i) will
comply with all requirements imposed upon it by the Act and the Exchange Act and
the respective rules and regulations of the Commission thereunder to the extent
necessary to permit the continuance of sales of or dealings in the Securities in
accordance with the provisions hereof and of the Prospectus and any Integrated
Prospectus, as then amended or supplemented, and (ii) will not file with the
Commission the Prospectus, Term Sheet, any Integrated Prospectus or any
amendment or supplement thereto or any amendment to the Registration Statement
of which the Representatives shall not previously have been advised and
furnished with a copy for a reasonable period of time prior to the proposed
filing and as to which filing the Representatives shall not have given their
consent. The Company will prepare and file with the Commission, in accordance
with the rules and regulations of the Commission, promptly upon request by the
Representatives or counsel for the Underwriters, any amendment to the
Registration Statement or amendment or supplement to the Prospectus and any
Integrated Prospectus that may be necessary or advisable in connection with the
distribution of the Securities by the several Underwriters, and will use its
best efforts to cause any such amendment to the Registration Statement to be
declared effective by the Commission as promptly as possible. The Company will
advise the Representatives,


                                       16
<PAGE>

promptly after receiving notice thereof, of the time when any amendment to the
Registration Statement has been filed or declared effective or the Prospectus,
any Integrated Prospectus or any amendment or supplement thereto has been filed
and will provide evidence satisfactory to the Representatives of each such
filing or effectiveness.

                  (b) The Company will advise the Representatives, promptly
after receiving notice or obtaining knowledge thereof, of (i) the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement or any post-effective amendment thereto or any order
directed at any document incorporated by reference in the Registration
Statement, the Prospectus or any Integrated Prospectus or any amendment or
supplement thereto or any order preventing or suspending the use of any
Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any
amendment or supplement thereto, (ii) the suspension of the qualification of the
Securities for offering or sale in any jurisdiction, (iii) the institution,
threatening or contemplation of any proceeding for any such purpose or (iv) any
request made by the Commission for amending the Registration Statement, for
amending or supplementing any Preliminary Prospectus, the Prospectus or any
Integrated Prospectus or for additional information. The Company will use its
best efforts to prevent the issuance of any such stop order and, if any such
stop order is issued, to obtain the withdrawal thereof as promptly as possible.

                  (c) If required by applicable law, the Company will arrange
for the qualification of the Securities and any Underlying Securities for
offering and sale under the securities or blue sky laws of such jurisdictions as
the Representatives may designate and will continue such qualifications in
effect for as long as may be necessary to complete the distribution of the
Securities and any Underlying Securities; provided, however, that in connection
therewith the Company shall not be required to qualify as a foreign corporation
or to execute a general consent to service of process in any jurisdiction.

                  (d) If at any time when a prospectus relating to the
Securities is required to be delivered under the Act, any event occurs as a
result of which the Prospectus or any Integrated Prospectus, as then amended or
supplemented, would include any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, or if for
any other reason it is necessary at any time to amend or supplement the
Prospectus or any Integrated Prospectus to comply with the Act or Exchange Act
or the respective rules or regulations of the Commission thereunder, the Company
will promptly notify the Representatives thereof and, subject to Section 4(a) of
this Agreement, will prepare and file with the Commission, at the Company's
expense, an amendment to the Registration Statement or an amendment or
supplement to the Prospectus and any Integrated Prospectus that corrects such
statement or omission or effects such compliance.


                                       17

                  (e) The Company will, without charge, provide (i) to the
Representatives and to counsel for the Underwriters, a conformed copy of the
registration statement originally filed with respect to the Securities and any
amendment thereto (in each case including exhibits thereto), (ii) to each other
Underwriter, a conformed copy of such registration statement and any amendment
thereto relating to the Securities (in each case without exhibits thereto) and
(iii) so long as a prospectus relating to the Securities is required to be
delivered under the Act, as many copies of each Preliminary Prospectus, the
Prospectus or any Integrated Prospectus or any amendment or supplement thereto
as the Representatives may reasonably request; without limiting the application
of clause (iii) of this sentence, the Company, not later than (A) 6:00 p.m., New

such determination occurred at or prior to 10:00 AM, New York City time, on such
date or (B) 12:00 Noon, New York City time, on the business day following the
date of determination of the public offering price, if such determination
occurred after 10:00 AM, New York city time, on such date, will deliver to the
Representatives, without charge, as many copies of the Prospectus or any
Integrated Prospectus and any amendment or supplement thereto as the
Representatives may reasonably request for purposes of confirming orders that
are expected to settle on the Firm Closing Date.

                  (f) The Company, as soon as practicable, will make generally
available to its securityholders and to the Representatives a consolidated
earning statement of the Company and its subsidiaries that satisfies the
provisions of Section 11(a) of the Act and Rule 158 thereunder.

                  (g) The Company will apply the net proceeds from the sale of
the Securities as set forth under "Use of Proceeds" in the Prospectus and any
Integrated Prospectus.

                  (h) The Company will not, directly or indirectly, without the
prior written consent of Prudential Securities Incorporated, on behalf of the
Underwriters, offer, sell, offer to sell, contract to sell, pledge, grant any
option to purchase or otherwise sell or dispose (or announce any offer, sale,
offer of sale, contract of sale, pledge, grant of any option to purchase or
other sale or disposition) of (i) any securities of the Company that are
substantially similar to the Securities or the Underlying Securities, (ii) any
securities convertible into, or exchangeable or exercisable for, the Securities
or Underlying Securities to any unaffiliated third party for a period commencing
on the date hereof and terminating 90 days after the date of the Prospectus or
any Integrated Prospectus, except pursuant to this agreement; provided, however,
that the Company may issue shares of Common Stock in exchange for Units existing
at the date of this Agreement. Prudential Securities Incorporated, at any time
and without notice, may release all or any portion of the securities subject to
such agreement.

                  (i) If required as set forth in Schedule 1 hereto, the Company
will obtain the agreements described in Section 6(g) hereof prior to the Firm
Closing Date.

                  (j) The Company will not, directly or indirectly, (i) take any
action designed to cause or to result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) (A) sell, bid for, purchase, or pay anyone any compensation
for soliciting purchases of the Securities or (B) pay or agree to pay to any
person any compensation for soliciting another to purchase any other securities
of the Company.

                  (k) If at any time during the 25-day period after the
Registration Statement becomes effective or the period prior to the Option
Closing Date, any rumor, publication or event relating to or affecting the
Company shall occur as a result of which in your opinion the market price of the
Common Stock has been or is likely to be materially affected (regardless of
whether such rumor, publication or event necessitates a supplement to or
amendment of the Prospectus or any Integrated Prospectus), the Company will,
after written notice from you advising the Company to the effect set forth
above, forthwith prepare, consult with you concerning the substance of, and
disseminate a press release or other public statement, reasonably satisfactory
to you, responding to or commenting on such rumor, publication or event.

                  (l) If required as set forth in Schedule 1 hereto, the Company

the Underwriters) and (ix) advertising relating to the offering of the
Securities requested by the Company (other than as shall have been specifically
approved by the Representatives to be paid for by the Underwriters). If the sale

this Agreement or because of any failure, refusal or inability on the part of

demand for all out-of-pocket expenses (including counsel fees and disbursements)
that shall have been incurred by them in connection with the proposed purchase
and sale of the Securities. The Company shall not in any event be liable to any
of the Underwriters for the loss of anticipated profits from the transactions

                  (b) The Representatives shall have received an opinion, dated
the Firm Closing Date, from Pryor, Cashman, Sherman & Flynn, counsel for the
Company, to the effect that:

                        (i) 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 the Subsidiaries,
      taken as a whole. Each of the Subsidiaries has been duly organized and is
      validly existing as a general or limited partnership or corporation in
      good standing under the laws of the jurisdiction of its organization, 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 the Subsidiaries, taken as a
      whole;

                        (ii) the Company and each of the Subsidiaries have full
      power, corporate or other, to own or lease their respective properties and
      conduct their respective businesses as described in the Registration
      Statement, the Prospectus and any Integrated Prospectus and each of the
      Company and the Subsidiaries have full power, corporate or other, to enter
      into this Agreement and the Securities Documents and to carry out all the
      terms and provisions hereof and thereof to be carried out by it;

                        (iii) the issued shares of capital stock of each of the
      Subsidiaries that is a corporation are duly authorized, validly issued,
      fully paid and nonassessable, and all of the partnership interests in each
      Subsidiary that is a partnership are validly issued and fully paid. Except
      as described in the Registration Statement, the Prospectus and any
      Integrated Prospectus, all of such shares and interests owned by the
      Company or another Subsidiary are owned beneficially by the Company or
      such Subsidiary free and clear of any security interest, mortgage, pledge,
      lien, encumbrance, equity or claim;

                        (iv) the Company has an authorized, issued and
      outstanding capitalization as set forth in the Prospectus and any
      Integrated Prospectus (or, if the Prospectus and any required Integrated
      Prospectus are not in existence, the most recent Preliminary Prospectus).
      All of the capital stock of the Company has been duly authorized and the

Agreement as specified in Schedule 1 hereto and the Firm Closing Date, in form
and substance satisfactory to the Representatives, to the effect that:

                        (i) they are independent accountants with respect to the
      Company and its subsidiaries within the meaning of the Act, the Exchange
      Act and the applicable published rules and regulations thereunder;


                                       26
<PAGE>

                        (ii) in their opinion, the financial statements audited
      by them and incorporated by reference in the Registration Statement, the
      Prospectus and any Integrated Prospectus comply as to form in all material
      respects with the applicable accounting requirements of the Act, the
      Exchange Act and the related published rules and regulations thereunder;

      the board of directors and any committees thereof of the Company and each
      of its consolidated subsidiaries, and inquiries of certain officials of
      the Company and its consolidated subsidiaries who have responsibility for
      financial and accounting matters, nothing came to their attention that
      caused them to believe that:

                        (A) (i) any unaudited consolidated condensed financial
                  statements of the Company and its consolidated subsidiaries
                  included in the Registra tion Statement, the Prospectus and
                  any Integrated Prospectus do not comply as to form in all
                  material respects with the applicable accounting require ments
                  of the Act, the Exchange Act and the related published rules
                  and regulations thereunder, or (ii) any material modification
                  should be made to the unaudited consolidated condensed
                  financial statements for them to be in conformity with
                  generally accepted accounting principles;

                        (B) at a specific date not more than five business days
                  prior to the date of such letter, there were any changes in
                  the common stock or increase in mortgages and loans payable of
                  the Company and its consolidated subsidiaries, in each case
                  compared with amounts shown on the most recent consolidated
                  balance sheet included in the Registration Statement, the
                  Prospectus and any Integrated Prospectus, except for such
                  changes set forth in such letter;

                        (iv) they have carried out certain specified procedures,
      not constituting an audit, with respect to certain amounts, percentages
      and financial information that are derived from the general accounting
      records of the Company and its consolidated subsidiaries and are included
      in the Registration Statement, the Prospectus and any Integrated
      Prospectus and in Exhibit 12 to the Registration Statement, including the
      information included or incorporated in the Company's most recent Annual
      Report on Form 10-K under the captions "Business" (Item 1), "Selected
      Financial Data" (Item 6) and "Management's Discussion and Analysis of
      Financial Condition and Results of Operations" (Item 7) and the
      information included or incorporated in the Company's Quarterly Reports on
      Form 10-Q under the caption "Management's Discussion and 


                                       27
<PAGE>

      Analysis of Financial Condition and Results of Operations,"and have
      compared such amounts, percentages and financial information with such
      records and with information derived from such records and have found them
      to be in agreement, excluding any questions of legal interpretation; and

                        (v) on the basis of a reading of any unaudited pro forma
      consolidated condensed financial statements included in the Registration
      Statement, the Prospectus and any Integrated Prospectus, carrying out
      certain specified procedures that would not necessarily reveal matters of
      significance with respect to the comments set forth in this paragraph (v),
      inquiries of certain officials of the Company, its consolidated
      subsidiaries and any acquired company who have responsibility for
      financial and accounting matters and proving the arithmetic accuracy of
      the application of the pro forma adjustments to the historical amounts in
      the unaudited pro forma consolidated condensed financial statements,
      nothing came to their attention that caused them to believe that the
      unaudited pro forma consolidated condensed financial statements do not
      comply in form in all material respects with the applicable accounting
      requirements of Rule 11-02 of Regulation S-X or that the pro forma
      adjustments have not been properly applied to the historical amounts in
      the compilation of such statements.

            In the event that the letters referred to above set forth any such
      changes, decreases or increases, it shall be a further condition to the
      obligations of the Underwriters that (A) such letters shall be accompanied
      by a written explanation of the Company as to the significance thereof,
      unless the Representatives deem such explanation unnecessary, and (B) such
      changes, decreases or increases do not, in the sole judgment of the
      Representa tives, make it impractical or inadvisable to proceed with the
      purchase and delivery of the Securities as contemplated by the
      Registration Statement.

            References to the Registration Statement, the Prospectus and any
      Integrated Prospectus in this paragraph (d) with respect to either letter
      referred to above shall include any amendment or supplement thereto at the
      date of such letter.

                  (e) The Representatives shall have received a certificate,
dated the Firm Closing Date, of the chief executive officer and the chief
financial or accounting officer of the Company to the effect that:

      this Agreement are true and correct as if made on and as of the Firm
      Closing Date; the Registration Statement, as amended as of the Firm

      statements therein not misleading, and the Prospectus or any Integrated
      Prospectus, as amended or supplemented as of the Firm Closing Date, does

      material fact necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading; and

      Company's knowledge, are contemplated by the Commission; and

                        (iii) subsequent to the respective dates as of which
      information is given in the Registration Statement, the Prospectus and any
      Integrated Prospectus, neither the Company nor any of its subsidiaries has
      sustained any material loss or interference with their respective
      businesses or properties from fire, flood, hurricane, accident or other
      calamity, whether or not covered by insurance, or from any labor dispute
      or any legal or governmental proceeding, and there has not been any
      material adverse change, or any development involving a prospective

      material fact required to be stated therein or necessary to make the
      statements therein not misleading or

                        (iv) any untrue statement or alleged untrue statement of
      any material fact contained in any audio or visual materials used in
      connection with the marketing of the Securities, including, without
      limitation, slides, videos, films and tape recordings,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement or
any amendment thereto, any Preliminary Prospectus, the Prospectus or any
Integrated Prospectus or any amendment or supplement thereto, or any Application
in reliance upon and in conformity with written information furnished to the
Company by such Underwriter through the Representatives specifically for use
therein. This indemnity agreement will be in addition to any liability which the
Company may otherwise have. The Company will not, without the prior written
consent of the Underwriter or Underwriters purchasing, in the aggregate, more
than 50% of the Firm Securities, settle or compromise or consent to the entry of
any judgment in any pending or threatened claim, action, suit or proceeding in
respect of which indemnification may be sought hereunder (whether or not any
such Underwriter or any person who controls any such Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act is a party to
such claim, action, suit or proceeding), unless such settlement, compromise or
consent includes an unconditional release of all of the Underwriters and such
controlling persons from all liability arising out of such claim, action, suit
or proceeding.

                  (b) Each Underwriter, severally and not jointly, will
indemnify and hold harmless the Company, each of its directors, each of its
officers who signed the Registration Statement, as amended at the date of this
Agreement as specified in Schedule 1 hereto, and each person, if any, who
controls the Company within the meaning of Section 15 of the Act or Section 20
of the Exchange Act against any losses, claims, damages or liabilities to which
the Company or any such director, officer or controlling person may become
subject under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement, as amended at the date of this Agreement as
specified in Schedule 1 hereto, any Preliminary Prospectus, the Prospectus or
any Integrated Prospectus or any amendment or supplement thereto, or any
Application or (ii) the omission or the alleged 


                                       31
<PAGE>

omission to state therein a material fact required to be stated in the
Registration Statement, as amended at the date of this Agreement as specified in
Schedule 1 hereto, any Preliminary Prospectus, the Prospectus or any Integrated
Prospectus or any amendment or supplement thereto, or any Application or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through the Representatives specifically for use therein; and, subject to the
limitation set forth immediately preceding this clause, will reimburse, as
incurred, any legal or other expenses reasonably incurred by the Company or any
such director, officer or controlling person in connection with investigating or
defending any such loss, claim, damage, liability or any action in respect
thereof. This indemnity agreement will be in addition to any liability which
such Underwriter may otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 7, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than under
this Section 7. In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof, with counsel satisfactory to such indemnified
party; provided, however, that if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified
party or parties. After notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying
party will not be liable to such indemnified party under this Section 7 for any
legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense
thereof, unless (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated by the Representatives in the case of
paragraph 


                                       32
<PAGE>

(a) of this Section 7, representing the indemnified parties under such paragraph
(a) who are parties to such action or actions) or (ii) the indemnifying party
does not promptly retain counsel satisfactory to the indemnified party or (iii)
the indemnifying party has authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party. After such notice
from the indemnifying party to such indemnified party, the indemnifying party
will not be liable for the costs and expenses of any settlement of such action
effected by such indemnified party without the consent of the indemnifying
party.

                  (d) In circumstances in which the indemnity agreement provided
for in the preceding paragraphs of this Section 7 is unavailable or
insufficient, for any reason, to hold harmless an indemnified party in respect
of any losses, claims, damages or liabilities (or actions in respect thereof),
each indemnifying party, in order to provide for just and equitable
contribution, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities (or actions in
respect thereof) in such proportion as is appropriate to reflect (i) the
relative benefits received by the indemnifying party or parties on the one hand
and the indemnified party on the other from the offering of the Securities or
(ii) if the allocation provided by the foregoing clause (i) is not permitted by
applicable law, not only such relative benefits but also the relative fault of
the indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions or alleged statements
or omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total proceeds from the offering (before deducting expenses) received by
the Company bear to the total underwriting discounts and commissions received by
the Underwriters. The relative fault of the parties shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Underwriters, the parties'
relative intents, knowledge, access to information and opportunity to correct or
prevent such statement or omission, and any other equitable consider ations
appropriate in the circumstances. The Company and the Underwriters agree that it
would not be equitable if the amount of such contribution were determined by pro
rata or per capita allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
into account the equitable considerations referred to above in this paragraph
(d). Notwithstanding any other provision of this paragraph (d), no Underwriter
shall be obligated to make contributions hereunder that in the aggregate exceed
the total public offering price of the Securities purchased by such Underwriter
under this Agreement, less the aggregate amount of any damages that such
Underwriter has otherwise been required to pay in respect of the same or any
substantially similar claim, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution


                                       33
<PAGE>

from any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute hereunder are several in proportion to
their respective underwriting obligations and not joint, and contributions among
Underwriters shall be governed by the provisions of the Prudential Securities
Incorporated Master Agreement Among Underwriters. For purposes of this paragraph
(d), each person, if any, who controls an Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act shall have the same
rights to contribution as such Underwriter, and each director of the Company,
each officer of the Company who signed the Registration Statement as amended at
the date of this Agreement as specified in Schedule 1 hereto and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, shall have the same rights to contribution as
the Company.

            8. Default of Underwriters. If one or more Underwriters default in
their obligations to purchase Firm Securities or Option Securities hereunder and
the aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase. If one or more Underwriters so default with respect to an aggregate
number of Securities that is more than ten percent of the aggregate number of
Firm Securities or Option Securities, as the case may be, to be purchased by all
of the Underwriters at such time hereunder, and if arrangements satisfactory to
the Representatives are not made within 36 hours after such default for the
purchase by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company other than as provided
in Section 9 hereof. In the event of any default by one or more Underwriters as
described in this Section 8, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 of this Agreement for not more than seven
business days in order that any necessary changes may be made in the
arrangements or documents for the purchase and delivery of the Firm Securities
or Option Securities, as the case may be. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 8. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.


                                       34

            9. Survival. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, its officers and the
several Underwriters set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the Company,
any of its officers or directors, any Underwriter or any controlling person
referred to in Section 7 hereof and (ii) delivery of and payment for the
Securities. The respective agreements, covenants, indemnities and other
statements set forth in Sections 5 and 7 hereof shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement.

            10. Termination. (a) This Agreement may be terminated with respect
to the Firm Securities or any Option Securities in the sole discretion of the
Representatives by notice to the Company given prior to the Firm Closing Date or
the related Option Closing Date, respectively, in the event that the Company
shall have failed, refused or been unable to perform all obligations and satisfy
all conditions on its part to be performed or satisfied hereunder at or prior
thereto or, if at or prior to the Firm Closing Date or such Option Closing Date,
respectively,

                        (i) the Company or any of the Subsidiaries shall have,
      in the sole judgment of the Representatives, sustained any material loss
      or interference with their respective businesses or properties from fire,
      flood, hurricane, accident or other calamity, whether or not covered by
      insurance, or from any labor dispute or any legal or governmental
      proceeding or there shall have been any material adverse change, or any
      development involving a prospective material adverse change (including
      without limitation a change in management or control of the Company, which
      includes the termination of the employment of John J. Cali or Thomas A.
      Rizk), in the condition (financial or otherwise), business prospects, net
      worth or results of operations of the Company and the Subsidiaries, except
      in each case as described in or contemplated by the Prospectus (exclusive
      of any amendment or supplement thereto);

                        (ii) trading in the Common Stock shall have been
      suspended by the Commission or the New York Stock Exchange or trading in
      securities generally on the New York Stock Exchange shall have been
      suspended or minimum or maximum prices shall have been established on such
      exchange;

                        (iii) there shall have been any downgrading in the
      rating of any debt securities or preferred stock of the Company by any
      "nationally recognized statistical rating organization" (as defined for
      purposes of Rule 436(g) under the Act), or any public announcement that
      any such organization has under surveillance or review its rating of any
      debt securities or preferred stock of the Company (other than an
      announcement with


                                       35
<PAGE>

      positive implications of a possible upgrading, and no implication of a
      possible downgrad ing, of such rating);

                        (iv) a banking moratorium shall have been declared by
      New York or United States authorities; or

                        (v) there shall have been (A) an outbreak or escalation
      of hostilities between the United States and any foreign power, (B) an
      outbreak or escalation of any other insurrection or armed conflict
      involving the United States or (C) any other calamity or crisis or
      material adverse change in general economic, political or financial
      conditions having an effect on the U.S. financial markets that, in the
      sole judgment of the Representatives, makes it impractical or inadvisable
      to proceed with the public offering or the delivery of the Securities as
      contemplated by the Registration Statement, as amended at the date of this
      Agreement as specified in Schedule 1 hereto

                  (b) Termination of this Agreement pursuant to this Section 10
shall be without liability of any party to any other party except as provided in
Section 9 hereof.

            11. Information Supplied by Underwriters. The statements set forth
in the last paragraph on the front cover page of the Prospectus Supplement and
under the heading "Underwriting" in the Prospectus Supplement (to the extent
such statements relate to the Underwriters) constitute the only information
furnished by any Underwriter through the Representatives to the Company for the
purposes of Sections 2(b) and 7(b) hereof. The Underwriters confirm that such
statements (to such extent) are correct.

            12. Notices. All communications hereunder shall be in writing and,

                                       36

                             UNDERWRITING AGREEMENT

                                                               February 19, 1998

To the Representatives named in Schedule 1 hereto of the 
  several Underwriters named in Schedule 2 hereto

Ladies and Gentlemen:

            Mack-Cali Realty Corporation, a Maryland corporation qualified as a
real estate investment trust (the "Company"), hereby confirms its agreement with
the several underwriters named in Schedule 2 hereto (the "Underwriters"), for
whom you have been duly authorized to act as representatives (in such
capacities, the "Representatives"), as set forth below. If you are the only
Underwriters, all references herein to the Representatives shall be deemed to be
to the Underwriters.

            1. Securities. Subject to the terms and conditions herein contained,
the Company proposes to issue and sell to the several Underwriters certain
securities of the Company identified in Schedule 1 hereto (the "Firm

As used in this Agreement, the term "Registration Statement" means such

Rule 434 under the Act, the Term Sheet relating to the Securities that is first
filed pursuant to Rule 424(b)(7) under the Act, together with the Preliminary
Prospectus identified therein that such Term Sheet supplements; (B) if the
Company does not rely on Rule 434 under the Act, the Preliminary Prospectus; or

pursuant to Rules 434(c)(2) and 424(b) under the Act; and the term "Term Sheet"
means any abbreviated term sheet that satisfies the requirements of Rule 434

<PAGE>

to an "amendment" or "supplement" to any Preliminary Prospectus, the Prospectus,
or any Integrated Prospectus or an "amendment" to any registration statement
(including the Registration Statement) shall be deemed to include any document
incorporated by reference therein that is filed with the Commission under the
Exchange Act after the date of such Preliminary Prospectus, Prospectus,
Integrated Prospectus or registration statement, as the case may be. For
purposes of the preceding sentence, any reference to the "effective date" of an
amendment to a registration statement shall, if such amendment is effected by
means of the filing with the Commission under the Exchange Act of a document
incorporated by reference in such registration statement, be deemed to refer to
the date on which such document was so filed with the Commission; any reference
herein to the "date" of a Prospectus that includes a Term Sheet shall mean the

                  (b) The Commission has not issued any order preventing or
suspending the use of any Preliminary Prospectus. When any Preliminary

required to be stated therein in accordance with, and complied in all material
respects with the requirements of, the Act, the Exchange Act and the respective
rules and regulations of the Commission thereunder and (ii) did not include any
untrue statement of a material fact or omit to state any material fact necessary

when the Prospectus is otherwise amended or supplemented and on the Firm Closing
Date and any Option Closing Date (both as hereinafter defined), each of the
Prospectus and, if required to be filed pursuant to Rules 434(c)(2) and 424(b)
under the Act, the Integrated Prospectus, as amended or supplemented at any such
time, (i) contained or will contain all statements required to be stated therein
in accordance with, and complied or will comply in all material respects with
the requirements of, the Act and the Exchange Act and the respective rules and
regulations of the Commission thereunder and (ii) did not or will not include
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. The foregoing
provisions of this paragraph (b) do not apply to statements or omissions made in
any Preliminary Prospectus or any amendment or supplement thereto, the
Registration Statement or any amendment thereto, the Prospectus or, if required
to be filed pursuant to Rules 434(c)(2) and 424(b) under the Act, the Integrated
Prospectus or any

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

or the related Option Closing Date (as the case may be), the Securities will
have been duly executed and delivered by the Company, and if applicable,

other than the Company, will be the legal, valid, binding and enforceable
obligations of the Company, 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.

the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

violation of any term or provision of its Articles of Incorporation, By-laws,
partnership agreements or other organizational documents, as the case may be; no
default exists, and no event has occurred which, with notice or lapse of time or

            3. Purchase, Sale and Delivery of the Securities.

                  (a) On the basis of the representations, warranties,
agreements and covenants herein contained and subject to the terms and
conditions herein set forth, the Company agrees to issue and sell to each of the
Underwriters, and each of the Underwriters, severally and not jointly, agrees to
purchase from the Company, at the purchase price specified in Schedule 1 hereto,
the number of Firm Securities set forth opposite the name of such Underwriter in
Schedule 2 hereto. One or more certificates in definitive form for the Firm
Securities that the several Underwriters have agreed to purchase hereunder, and
in such denomination or denominations and registered in such name or names as
the Representatives request upon notice to the Company at


                                       14
<PAGE>

least 48 hours prior to the Firm Closing Date, shall be delivered by or on
behalf of the Company to the Representatives for the respective accounts of the
Underwriters, against payment by or on behalf of the Underwriters of the
purchase price therefor to the Company in such funds as are specified in
Schedule 1 hereto. Such delivery of and payment for the Firm Securities shall be
made at the date, time and place identified in Schedule 1 hereto, or at such
other date, time or place as the Representatives and the Company may agree upon
or as the Representatives may determine pursuant to Section 8 hereof, such date
and time of delivery against payment being herein referred to as the "Firm
Closing Date". The Company will make such certificate or certificates for the
Firm Securities available for checking and packaging by the Representatives at
the offices in New York, New York of the Company's transfer agent or registrar
or warrant agent or of Prudential Securities Incorporated at least 24 hours
prior to the Firm Closing Date.

                  (b) For the purpose of covering any over-allotments in
connection with the distribution and sale of the Firm Securities as contemplated
by the Prospectus and any Integrated Prospectus, the Company hereby grants to
the several Underwriters an option to purchase, severally and not jointly, the
Option Securities. The purchase price to be paid for any Option Securities shall
be the same price per share as the price per share for the Firm Securities set
forth in Schedule 1 to this Agreement, plus, if the purchase and sale of any
Option Securities takes place after the Firm Closing Date and after the Firm
Securities are trading "ex-dividend", an amount equal to the dividends payable
on such Option Securities. The option granted hereby may be exercised as to all
or any part of the Option Securities from time to time within thirty days after
the date of the Prospectus or any Integrated Prospectus (or, if such 30th day
shall be a Saturday or Sunday or a holiday, on the next business day thereafter
when the New York Stock Exchange is open for trading). The Underwriters shall
not be under any obligation to purchase any of the Option Securities prior to
the exercise of such option. The Representatives may from time to time exercise
the option granted hereby by giving notice in writing or by telephone (confirmed
in writing) to the Company setting forth the aggregate number of Option
Securities as to which the several Underwriters are then exercising the option
and the date and time for delivery of and payment for such Option Securities.
Any such date of delivery shall be determined by the Representatives but shall
not be earlier than two business days or later than five business days after
such exercise of the option and, in any event, shall not be earlier than the
Firm Closing Date. The time and date set forth in such notice, or such other
time on such other date as the Representatives and the Company may agree upon or
as the Representatives may determine pursuant to Section 9 hereof, is herein
called the "Option Closing Date" with respect to such Option Securities. Upon
exercise of the option as provided herein, the Company shall become obligated to
sell to each of the several Underwriters, and, subject to the terms and
conditions herein set forth, each of the Underwriters (severally and not
jointly) shall become obligated to purchase from the Company the same percentage
of the total number of the Option Securities as


                                       15
<PAGE>

to which the several Underwriters are then exercising the option as such
Underwriter is obligated to purchase of the aggregate number of Firm Securities,
as adjusted by the Representatives in such manner as they deem advisable to
avoid fractional shares. If the option is exercised as to all or any portion of
the Option Securities, one or more certificates in definitive form for such
Option Securities, and payment therefor, shall be delivered on the related
Option Closing Date in the manner, and upon the terms and conditions, set forth
in paragraph (a) of this Section 3 and Schedule 1 to this Agreement, except that
reference therein to the Firm Securities and the Firm Closing Date shall be
deemed, for purposes of this paragraph (b), to refer to such Option Securities
and Option Closing Date, respectively.

                  (c) It is understood that any of you, individually and not as
one of the Representatives, may (but shall not be obligated to) make payment on
behalf of any Underwriter or Underwriters for any of the Securities to be
purchased by such Underwriter or Underwriters. No such payment shall relieve
such Underwriter or Underwriters from any of its or their obligations hereunder.

            4. Covenants of the Company. The Company covenants and agrees with
each of the Underwriters that:

                  (a) The Company will file the Prospectus or any Term Sheet
that constitutes a part thereof, any Integrated Prospectus or the Prospectus
Supplement, as the case may be, and any amendment or supplement thereto with the
Commission in the manner and within the time period required by Rules 434 and
424(b) under the Act. During any time when a prospectus relating to the
Securities is required to be delivered under the Act, the Company (i) will
comply with all requirements imposed upon it by the Act and the Exchange Act and
the respective rules and regulations of the Commission thereunder to the extent
necessary to permit the continuance of sales of or dealings in the Securities in
accordance with the provisions hereof and of the Prospectus and any Integrated
Prospectus, as then amended or supplemented, and (ii) will not file with the
Commission the Prospectus, Term Sheet, any Integrated Prospectus or any
amendment or supplement thereto or any amendment to the Registration Statement
of which the Representatives shall not previously have been advised and
furnished with a copy for a reasonable period of time prior to the proposed
filing and as to which filing the Representatives shall not have given their
consent. The Company will prepare and file with the Commission, in accordance
with the rules and regulations of the Commission, promptly upon request by the
Representatives or counsel for the Underwriters, any amendment to the
Registration Statement or amendment or supplement to the Prospectus and any
Integrated Prospectus that may be necessary or advisable in connection with the
distribution of the Securities by the several Underwriters, and will use its
best efforts to cause any such amendment to the Registration Statement to be
declared effective by the Commission as promptly as possible. The Company will
advise the Representatives,


                                       16
<PAGE>

promptly after receiving notice thereof, of the time when any amendment to the
Registration Statement has been filed or declared effective or the Prospectus,
any Integrated Prospectus or any amendment or supplement thereto has been filed
and will provide evidence satisfactory to the Representatives of each such
filing or effectiveness.

                  (b) The Company will advise the Representatives, promptly
after receiving notice or obtaining knowledge thereof, of (i) the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement or any post-effective amendment thereto or any order
directed at any document incorporated by reference in the Registration
Statement, the Prospectus or any Integrated Prospectus or any amendment or
supplement thereto or any order preventing or suspending the use of any
Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any
amendment or supplement thereto, (ii) the suspension of the qualification of the
Securities for offering or sale in any jurisdiction, (iii) the institution,
threatening or contemplation of any proceeding for any such purpose or (iv) any
request made by the Commission for amending the Registration Statement, for
amending or supplementing any Preliminary Prospectus, the Prospectus or any
Integrated Prospectus or for additional information. The Company will use its
best efforts to prevent the issuance of any such stop order and, if any such
stop order is issued, to obtain the withdrawal thereof as promptly as possible.

                  (c) If required by applicable law, the Company will arrange
for the qualification of the Securities and any Underlying Securities for
offering and sale under the securities or blue sky laws of such jurisdictions as
the Representatives may designate and will continue such qualifications in
effect for as long as may be necessary to complete the distribution of the
Securities and any Underlying Securities; provided, however, that in connection
therewith the Company shall not be required to qualify as a foreign corporation
or to execute a general consent to service of process in any jurisdiction.

                  (d) If at any time when a prospectus relating to the
Securities is required to be delivered under the Act, any event occurs as a
result of which the Prospectus or any Integrated Prospectus, as then amended or
supplemented, would include any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, or if for
any other reason it is necessary at any time to amend or supplement the
Prospectus or any Integrated Prospectus to comply with the Act or Exchange Act
or the respective rules or regulations of the Commission thereunder, the Company
will promptly notify the Representatives thereof and, subject to Section 4(a) of
this Agreement, will prepare and file with the Commission, at the Company's
expense, an amendment to the Registration Statement or an amendment or
supplement to the Prospectus and any Integrated Prospectus that corrects such
statement or omission or effects such compliance.


                                       17

                  (e) The Company will, without charge, provide (i) to the
Representatives and to counsel for the Underwriters, a conformed copy of the
registration statement originally filed with respect to the Securities and any
amendment thereto (in each case including exhibits thereto), (ii) to each other
Underwriter, a conformed copy of such registration statement and any amendment
thereto relating to the Securities (in each case without exhibits thereto) and
(iii) so long as a prospectus relating to the Securities is required to be
delivered under the Act, as many copies of each Preliminary Prospectus, the
Prospectus or any Integrated Prospectus or any amendment or supplement thereto
as the Representatives may reasonably request; without limiting the application
of clause (iii) of this sentence, the Company, not later than (A) 6:00 p.m., New
York city time, on the date of determination of the public offering price, if
such determination occurred at or prior to 10:00 AM, New York City time, on such
date or (B) 12:00 Noon, New York City time, on the business day following the
date of determination of the public offering price, if such determination
occurred after 10:00 AM, New York city time, on such date, will deliver to the
Representatives, without charge, as many copies of the Prospectus or any
Integrated Prospectus and any amendment or supplement thereto as the
Representatives may reasonably request for purposes of confirming orders that
are expected to settle on the Firm Closing Date.

                  (f) The Company, as soon as practicable, will make generally
available to its securityholders and to the Representatives a consolidated
earning statement of the Company and its subsidiaries that satisfies the
provisions of Section 11(a) of the Act and Rule 158 thereunder.

                  (g) The Company will apply the net proceeds from the sale of
the Securities as set forth under "Use of Proceeds" in the Prospectus and any
Integrated Prospectus.

                  (h) The Company will not, directly or indirectly, without the
prior written consent of Prudential Securities Incorporated, on behalf of the
Underwriters, offer, sell, offer to sell, contract to sell, pledge, grant any
option to purchase or otherwise sell or dispose (or announce any offer, sale,
offer of sale, contract of sale, pledge, grant of any option to purchase or
other sale or disposition) of (i) any securities of the Company that are
substantially similar to the Securities or the Underlying Securities, (ii) any
securities convertible into, or exchangeable or exercisable for, the Securities
or Underlying Securities to any unaffiliated third party for a period commencing
on the date hereof and terminating 90 days after the date of the Prospectus or
any Integrated Prospectus, except pursuant to this agreement; provided, however,
that the Company may issue shares of Common Stock in exchange for Units existing
at the date of this Agreement. Prudential Securities Incorporated, at any time
and without notice, may release all or any portion of the securities subject to
such agreement.

<PAGE>

                  (i) If required as set forth in Schedule 1 hereto, the Company
will obtain the agreements described in Section 6(g) hereof prior to the Firm
Closing Date.

                  (j) The Company will not, directly or indirectly, (i) take any
action designed to cause or to result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) (A) sell, bid for, purchase, or pay anyone any compensation
for soliciting purchases of the Securities or (B) pay or agree to pay to any
person any compensation for soliciting another to purchase any other securities
of the Company.

                  (k) If at any time during the 25-day period after the
Registration Statement becomes effective or the period prior to the Option
Closing Date, any rumor, publication or event relating to or affecting the
Company shall occur as a result of which in your opinion the market price of the
Common Stock has been or is likely to be materially affected (regardless of
whether such rumor, publication or event necessitates a supplement to or
amendment of the Prospectus or any Integrated Prospectus), the Company will,
after written notice from you advising the Company to the effect set forth
above, forthwith prepare, consult with you concerning the substance of, and
disseminate a press release or other public statement, reasonably satisfactory
to you, responding to or commenting on such rumor, publication or event.

                  (l) If required as set forth in Schedule 1 hereto, the Company

this Agreement or because of any failure, refusal or inability on the part of

demand for all out-of-pocket expenses (including counsel fees and disbursements)
that shall have been incurred by them in connection with the proposed purchase
and sale of the Securities. The Company shall not in any event be liable to any
of the Underwriters for the loss of anticipated profits from the transactions

      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

      validly existing as a general or limited partnership or corporation in
      good standing under the laws of the jurisdiction of its organization, 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

      liability or disability to the Company and the Subsidiaries, taken as a
      whole;

                        (ii) the Company and each of the Subsidiaries have full
      power, corporate or other, to own or lease their respective properties and

      Subsidiaries that is a corporation are duly authorized, validly issued,

      thereunder.

statement of a material fact


                                       25
<PAGE>

or omitted to state any material fact required to be stated therein or necessary

Jersey and Delaware or the United States, to the extent satisfactory in form and

Agreement as specified in Schedule 1 hereto and the Firm Closing Date, in form
and substance satisfactory to the Representatives, to the effect that:

                        (i) they are independent accountants with respect to the
      Company and its subsidiaries within the meaning of the Act, the Exchange
      Act and the applicable published rules and regulations thereunder;


                                       26
<PAGE>

                        (ii) in their opinion, the financial statements audited
      by them and incorporated by reference in the Registration Statement, the
      Prospectus and any Integrated Prospectus comply as to form in all material
      respects with the applicable accounting requirements of the Act, the
      Exchange Act and the related published rules and regulations thereunder;

                        (iii) a reading of the minute books of the shareholders,
      the board of directors and any committees thereof of the Company and each
      of its consolidated subsidiaries, and inquiries of certain officials of
      the Company and its consolidated subsidiaries who have responsibility for
      financial and accounting matters, nothing came to their attention that
      caused them to believe that:

                        (A) (i) any unaudited consolidated condensed financial
                  statements of the Company and its consolidated subsidiaries
                  included in the Registration Statement, the Prospectus and
                  any Integrated Prospectus do not comply as to form in all
                  material respects with the applicable accounting requirements
                  of the Act, the Exchange Act and the related published rules
                  and regulations thereunder, or (ii) any material modification
                  should be made to the unaudited consolidated condensed
                  financial statements for them to be in conformity with
                  generally accepted accounting principles;

                        (B) at a specific date not more than five business days
                  prior to the date of such letter, there were any changes in
                  the common stock or increase in mortgages and loans payable of
                  the Company and its consoli dated subsidiaries, in each case
                  compared with amounts shown on the most recent consolidated
                  balance sheet included in the Registration Statement, the
                  Prospectus and any Integrated Prospectus, except for such
                  changes set forth in such letter;

                        (iv) they have carried out certain specified procedures,
      not constituting an audit, with respect to certain amounts, percentages
      and financial information that are derived from the general accounting
      records of the Company and its consolidated subsidiaries and are included
      in the Registration Statement, the Prospectus and any Integrated
      Prospectus and in Exhibit 12 to the Registration Statement, including the
      information included or incorporated in the Company's most recent Annual
      Report on Form 10-K under the captions "Business" (Item 1), "Selected
      Financial Data" (Item 6) and "Management's Discussion and Analysis of
      Financial Condition and Results of Operations" (Item 7) and the
      information included or incorporated in the Company's Quarterly Reports on
      Form 10-Q under the caption "Management's Discussion and


                                       27
<PAGE>

      Analysis of Financial Condition and Results of Operations,"and have
      compared such amounts, percentages and financial information with such
      records and with information derived from such records and have found them
      to be in agreement, excluding any questions of legal interpretation; and

                        (v) on the basis of a reading of any unaudited pro forma
      consolidated condensed financial statements included in the Registration
      Statement, the Prospectus and any Integrated Prospectus, carrying out
      certain specified procedures that would not necessarily reveal matters of
      significance with respect to the comments set forth in this paragraph (v),
      inquiries of certain officials of the Company, its consolidated
      subsidiaries and any acquired company who have responsibility for
      financial and accounting matters and proving the arithmetic accuracy of
      the application of the pro forma adjustments to the historical amounts in
      the unaudited pro forma consolidated condensed financial statements,
      nothing came to their attention that caused them to believe that the
      unaudited pro forma consolidated condensed financial statements do not
      comply in form in all material respects with the applicable accounting
      requirements of Rule 11-02 of Regulation S-X or that the pro forma
      adjustments have not been properly applied to the historical amounts in
      the compilation of such statements.

            In the event that the letters referred to above set forth any such
      changes, decreases or increases, it shall be a further condition to the
      obligations of the Underwriters that (A) such letters shall be accompanied
      by a written explanation of the Company as to the significance thereof,
      unless the Representatives deem such explanation unnecessary, and (B) such
      changes, decreases or increases do not, in the sole judgment of the
      Representa tives, make it impractical or inadvisable to proceed with the
      purchase and delivery of the Securities as contemplated by the
      Registration Statement.

            References to the Registration Statement, the Prospectus and any
      Integrated Prospectus in this paragraph (d) with respect to either letter
      referred to above shall include any amendment or supplement thereto at the
      date of such letter.

dated the Firm Closing Date, of the chief executive officer and the chief
financial or accounting officer of the Company to the effect that:

<PAGE>

      statements therein not misleading, and the Prospectus or any Integrated
      Prospectus, as amended or supplemented as of the Firm Closing Date, does

      material fact necessary in order to make the statements therein, in the
      light of the circumstances under which they were made, not misleading; and

      Company's knowledge, are contemplated by the Commission; and

                        (iii) subsequent to the respective dates as of which
      information is given in the Registration Statement, the Prospectus and any
      Integrated Prospectus, neither the Company nor any of its subsidiaries has
      sustained any material loss or interference with their respective

      calamity, whether or not covered by insurance, or from any labor dispute
      or any legal or governmental proceeding, and there has not been any
      material adverse change, or any development involving a prospective

      Integrated Prospectus or any amendment or supplement thereto or (B) any
      application or other document, or any amendment or supplement thereto,
      executed by the Company or based upon written information furnished by or
      on behalf of the Company filed in any jurisdiction in order to qualify the
      Securities under the securities or blue sky laws thereof or filed with the
      Commission or any securities association or securities exchange (each an
      "Application"),

                        (iii) the omission or alleged omission to state in the
      Registration Statement or any amendment thereto, any Preliminary
      Prospectus, the Prospectus or any Integrated Prospectus or any amendment
      or supplement thereto, or any Application a


                                       30
<PAGE>

      material fact required to be stated therein or necessary to make the
      statements therein not misleading or

                        (iv) any untrue statement or alleged untrue statement of
      any material fact contained in any audio or visual materials used in
      connection with the marketing of the Securities, including, without
      limitation, slides, videos, films and tape recordings,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement or
any amendment thereto, any Preliminary Prospectus, the Prospectus or any
Integrated Prospectus or any amendment or supplement thereto, or any Application
in reliance upon and in conformity with written information furnished to the
Company by such Underwriter through the Representatives specifically for use
therein. This indemnity agreement will be in addition to any liability which the
Company may otherwise have. The Company will not, without the prior written
consent of the Underwriter or Underwriters purchasing, in the aggregate, more
than 50% of the Firm Securities, settle or compromise or consent to the entry of
any judgment in any pending or threatened claim, action, suit or proceeding in
respect of which indemnification may be sought hereunder (whether or not any
such Underwriter or any person who controls any such Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act is a party to
such claim, action, suit or proceeding), unless such settlement, compromise or
consent includes an unconditional release of all of the Underwriters and such
controlling persons from all liability arising out of such claim, action, suit
or proceeding.

                  (b) Each Underwriter, severally and not jointly, will
indemnify and hold harmless the Company, each of its directors, each of its
officers who signed the Registration Statement, as amended at the date of this
Agreement as specified in Schedule 1 hereto, and each person, if any, who
controls the Company within the meaning of Section 15 of the Act or Section 20
of the Exchange Act against any losses, claims, damages or liabilities to which
the Company or any such director, officer or controlling person may become
subject under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement, as amended at the date of this Agreement as
specified in Schedule 1 hereto, any Preliminary Prospectus, the Prospectus or
any Integrated Prospectus or any amendment or supplement thereto, or any
Application or (ii) the omission or the alleged


                                       31
<PAGE>

omission to state therein a material fact required to be stated in the
Registration Statement, as amended at the date of this Agreement as specified in
Schedule 1 hereto, any Preliminary Prospectus, the Prospectus or any Integrated
Prospectus or any amendment or supplement thereto, or any Application or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such Underwriter
through the Representatives specifically for use therein; and, subject to the
limitation set forth immediately preceding this clause, will reimburse, as
incurred, any legal or other expenses reasonably incurred by the Company or any
such director, officer or controlling person in connection with investigating or
defending any such loss, claim, damage, liability or any action in respect
thereof. This indemnity agreement will be in addition to any liability which
such Underwriter may otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 7, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than under
this Section 7. In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof, with counsel satisfactory to such indemnified
party; provided, however, that if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified
party or parties. After notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying
party will not be liable to such indemnified party under this Section 7 for any
legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense
thereof, unless (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated by the Representatives in the case of
paragraph


                                       32
<PAGE>

(a) of this Section 7, representing the indemnified parties under such paragraph
(a) who are parties to such action or actions) or (ii) the indemnifying party
does not promptly retain counsel satisfactory to the indemnified party or (iii)
the indemnifying party has authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party. After such notice
from the indemnifying party to such indemnified party, the indemnifying party
will not be liable for the costs and expenses of any settlement of such action
effected by such indemnified party without the consent of the indemnifying
party.

                  (d) In circumstances in which the indemnity agreement provided
for in the preceding paragraphs of this Section 7 is unavailable or
insufficient, for any reason, to hold harmless an indemnified party in respect
of any losses, claims, damages or liabilities (or actions in respect thereof),
each indemnifying party, in order to provide for just and equitable
contribution, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities (or actions in
respect thereof) in such proportion as is appropriate to reflect (i) the
relative benefits received by the indemnifying party or parties on the one hand
and the indemnified party on the other from the offering of the Securities or
(ii) if the allocation provided by the foregoing clause (i) is not permitted by
applicable law, not only such relative benefits but also the relative fault of
the indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions or alleged statements
or omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total proceeds from the offering (before deducting expenses) received by
the Company bear to the total underwriting discounts and commissions received by
the Underwriters. The relative fault of the parties shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Underwriters, the parties'
relative intents, knowledge, access to information and opportunity to correct or
prevent such statement or omission, and any other equitable considerations
appropriate in the circumstances. The Company and the Underwriters agree that it
would not be equitable if the amount of such contribution were determined by pro
rata or per capita allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
into account the equitable considerations referred to above in this paragraph
(d). Notwithstanding any other provision of this paragraph (d), no Underwriter
shall be obligated to make contributions hereunder that in the aggregate exceed
the total public offering price of the Securities purchased by such Underwriter
under this Agreement, less the aggregate amount of any damages that such
Underwriter has otherwise been required to pay in respect of the same or any
substantially similar claim, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution


                                       33
<PAGE>

from any person who was not guilty of such fraudulent misrepresentation. The
Underwriters' obligations to contribute hereunder are several in proportion to
their respective underwriting obligations and not joint, and contributions among
Underwriters shall be governed by the provisions of the Prudential Securities
Incorporated Master Agreement Among Underwriters. For purposes of this paragraph
(d), each person, if any, who controls an Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act shall have the same
rights to contribution as such Underwriter, and each director of the Company,
each officer of the Company who signed the Registration Statement as amended at
the date of this Agreement as specified in Schedule 1 hereto and each person, if
any, who controls the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, shall have the same rights to contribution as
the Company.

            8. Default of Underwriters. If one or more Underwriters default in
their obligations to purchase Firm Securities or Option Securities hereunder and
the aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase. If one or more Underwriters so default with respect to an aggregate
number of Securities that is more than ten percent of the aggregate number of
Firm Securities or Option Securities, as the case may be, to be purchased by all
of the Underwriters at such time hereunder, and if arrangements satisfactory to
the Representatives are not made within 36 hours after such default for the
purchase by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company other than as provided
in Section 9 hereof. In the event of any default by one or more Underwriters as
described in this Section 8, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 of this Agreement for not more than seven
business days in order that any necessary changes may be made in the
arrangements or documents for the purchase and delivery of the Firm Securities
or Option Securities, as the case may be. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 8. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.


                                       34

            9. Survival. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, its officers and the
several Underwriters set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the Company,
any of its officers or directors, any Underwriter or any controlling person
referred to in Section 7 hereof and (ii) delivery of and payment for the
Securities. The respective agreements, covenants, indemnities and other
statements set forth in Sections 5 and 7 hereof shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement.

            10. Termination. (a) This Agreement may be terminated with respect
to the Firm Securities or any Option Securities in the sole discretion of the
Representatives by notice to the Company given prior to the Firm Closing Date or
the related Option Closing Date, respectively, in the event that the Company
shall have failed, refused or been unable to perform all obligations and satisfy
all conditions on its part to be performed or satisfied hereunder at or prior
thereto or, if at or prior to the Firm Closing Date or such Option Closing Date,
respectively,

                        (i) the Company or any of the Subsidiaries shall have,
      in the sole judgment of the Representatives, sustained any material loss
      or interference with their respective businesses or properties from fire,
      flood, hurricane, accident or other calamity, whether or not covered by
      insurance, or from any labor dispute or any legal or governmental
      proceeding or there shall have been any material adverse change, or any
      development involving a prospective material adverse change (including
      without limitation a change in management or control of the Company, which
      includes the termination of the employment of Thomas A. Rizk), in the
      condition (financial or otherwise), business prospects, net worth or
      results of operations of the Company and the Subsidiaries, except in each
      case as described in or contemplated by the Prospectus (exclusive of any
      amendment or supplement thereto);

                        (ii) trading in the Common Stock shall have been
      suspended by the Commission or the New York Stock Exchange or trading in
      securities generally on the New York Stock Exchange shall have been
      suspended or minimum or maximum prices shall have been established on such
      exchange;

                        (iii) there shall have been any downgrading in the
      rating of any debt securities or preferred stock of the Company by any
      "nationally recognized statistical rating organization" (as defined for
      purposes of Rule 436(g) under the Act), or any public announcement that
      any such organization has under surveillance or review its rating of any
      debt securities or preferred stock of the Company (other than an
      announcement with


                                       35
<PAGE>

      positive implications of a possible upgrading, and no implication of a
      possible downgrading, of such rating);

                        (iv) a banking moratorium shall have been declared by
      New York or United States authorities; or

                        (v) there shall have been (A) an outbreak or escalation
      of hostilities between the United States and any foreign power, (B) an
      outbreak or escalation of any other insurrection or armed conflict
      involving the United States or (C) any other calamity or crisis or
      material adverse change in general economic, political or financial
      conditions having an effect on the U.S. financial markets that, in the
      sole judgment of the Representatives, makes it impractical or inadvisable
      to proceed with the public offering or the delivery of the Securities as
      contemplated by the Registration Statement, as amended at the date of this
      Agreement as specified in Schedule 1 hereto

                  (b) Termination of this Agreement pursuant to this Section 10
shall be without liability of any party to any other party except as provided in
Section 9 hereof.

            11. Information Supplied by Underwriters. The statements set forth
in the last paragraph on the front cover page of the Prospectus Supplement and
under the heading "Underwriting" in the Prospectus Supplement (to the extent
such statements relate to the Underwriters) constitute the only information
furnished by any Underwriter through the Representatives to the Company for the
purposes of Sections 2(b) and 7(b) hereof. The Underwriters confirm that such
statements (to such extent) are correct.

            12. Notices. All communications hereunder shall be in writing and,
if sent to any of the Underwriters, shall be delivered or sent by mail, telex or
facsimile transmission and confirmed in writing to Prudential Securities
Incorporated, One New York Plaza, New York, New York 10292, Attention: Equity

shall be binding upon the several Underwriters, the Company and their respective
successors and legal representatives, and nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any other person any legal
or equitable right, remedy or claim under or in respect of this Agreement, or
any provisions herein contained, this Agreement and all conditions and
provisions hereof being intended to be and being for the sole and exclusive
benefit of such persons and for the benefit of no other person except that (i)
the indemnities of the Company


                                       36
<PAGE>

contained in Section 7 of this Agreement shall also be for the benefit of any
person or persons who control any Underwriter within the meaning of Section 15
of the Act or Section 20 of the Exchange Act and (ii) the indemnities of the
Underwriters contained in Section 7 of this Agreement shall also be for the

AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
GIVING EFFECT TO ANY PROVISIONS RELATING TO CONFLICTS OF LAWS.

                                                                  March 24, 1998

To the Representatives named in Schedule 1 hereto of the 
  several Underwriters named in Schedule 2 hereto

Ladies and Gentlemen:

            Mack-Cali Realty Corporation, a Maryland corporation qualified as a
real estate investment trust (the "Company"), hereby confirms its agreement with
the several underwriters named in Schedule 2 hereto (the "Underwriters"), for
whom you have been duly authorized to act as representatives (in such
capacities, the "Representatives"), as set forth below. If you are the only
Underwriters, all references herein to the Representatives shall be deemed to be
to the Underwriters.

            1. Securities. Subject to the terms and conditions herein contained,
the Company proposes to issue and sell to the several Underwriters certain
securities of the Company identified in Schedule 1 hereto (the "Firm
Securities"). The Company also proposes to issue and sell to the several
Underwriters the additional securities identified in Schedule 1 if requested by
the Representatives as provided in Section 3 of this Agreement. Any and all
shares of such additional securities to be purchased by the several Underwriters
pursuant to such option are referred to herein as the "Option Securities," and
the Firm Securities and any Option Securities are collectively referred to
herein as the "Securities."

            2. Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, each of the several Underwriters
that:

                  (a) The Company meets the requirements for use of Form S-3
under the Securities Act of 1933, as amended (the "Act"). A registration
statement (the file number of which is set forth in Schedule 1 hereto) on such
Form with respect to the Securities, 
<PAGE>

including a basic prospectus, has been filed by the Company with the Securities
and Exchange Commission (the "Commission") under the Act, and one or more
amendments to such registration statement may also have been so filed. Such
registration statement, as so amended, has been declared by the Commission to be
effective under the Act. Such registration statement, as amended at the date of
this Agreement as specified in Schedule 1 hereto, meets the requirements set
forth in Rule 415(a)(1)(x) under the Act and complies in all other material
respects with said Rule. The Company will next file with the Commission either
(A) if the Company relies on Rule 434 under the Act, a Term Sheet (as
hereinafter defined) relating to the Securities, that shall identify the
Preliminary Prospectus (as hereinafter defined) that it supplements and, if
required to be filed pursuant to Rules 434(c)(2) and 424(b), an Integrated

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.

will have been duly executed and delivered by the Company, and assuming due
authorization, execution and delivery of the Securities Documents by parties
other than the Company as specified in the applicable Securities Documents, and,
if required, such Securities Documents have been filed with the Secretary of

enforceable against the Company in accordance with their respective terms,

Rule 11-02 of Regulation S-X of the Commission and the pro forma adjustments
have been properly applied to the historical amounts in the compilation of such

violation of any term or provision of its Articles of Incorporation, By-laws,
partnership agreements or other organizational documents, as the case may be; no

<PAGE>

Registration Statement or any amendment thereto, any Preliminary Prospectus, the

            3. Purchase, Sale and Delivery of the Securities.

                  (a) On the basis of the representations, warranties,
agreements and covenants herein contained and subject to the terms and
conditions herein set forth, the Company agrees to issue and sell to each of the
Underwriters, and each of the Underwriters, severally and not jointly, agrees to
purchase from the Company, at the purchase price specified in Schedule 1 hereto,
the number of Firm Securities set forth opposite the name of such Underwriter in
Schedule 2 hereto. One or more certificates in definitive form for the Firm
Securities that the several Underwriters have agreed to purchase hereunder, and
in such denomination or denominations and registered in such name or names as
the Representatives request upon notice to the Company at least 48 hours prior
to the Firm Closing Date, shall be delivered by or on behalf of the Company to
the Representatives for the respective accounts of the Underwriters, against
payment by or on behalf of the Underwriters of the purchase price therefor to
the Company in such funds as are specified in Schedule 1 hereto. Such delivery
of and payment for the Firm Securities shall be made at the date, time and place
identified in Schedule 1 hereto, or at such other date, time or place as the
Representatives and the Company may agree upon or as the Representatives may
determine pursuant to Section 8 hereof, such date and time of delivery against
payment being herein referred to as the "Firm Closing Date". The Company will
make such certificate or certificates for the Firm Securities available for
checking and packaging by the Representatives at the offices in New York, New
York of the Company's transfer agent or registrar or warrant agent or of Wheat
First Securities, Inc. at least 24 hours prior to the Firm Closing Date.

                  (b) For the purpose of covering any over-allotments in
connection with the distribution and sale of the Firm Securities as contemplated
by the Prospectus and any Integrated Prospectus, the Company hereby grants to
the several Underwriters an option to purchase, severally and not jointly, the
Option Securities. The purchase price to be paid for any Option Securities shall
be the same price per share as the price per share for the Firm Securities set
forth in Schedule 1 to this Agreement, plus, if the purchase and sale of any
Option Securities takes place after the Firm Closing Date and after the Firm
Securities are trading "ex-dividend", an amount equal to the dividends payable
on such Option Securities. The option granted hereby may be exercised as to all
or any part of the Option Securities from time to time within thirty days after
the date of the Prospectus or any Integrated Prospectus (or, if such 30th day
shall be a Saturday or Sunday or a holiday, on the next business day thereafter
when the New York Stock Exchange is open for trading). The Underwriters shall


                                       15
<PAGE>

not be under any obligation to purchase any of the Option Securities prior to
the exercise of such option. The Representatives may from time to time exercise
the option granted hereby by giving notice in writing or by telephone (confirmed
in writing) to the Company setting forth the aggregate number of Option
Securities as to which the several Underwriters are then exercising the option
and the date and time for delivery of and payment for such Option Securities.
Any such date of delivery shall be determined by the Representatives but shall
not be earlier than two business days or later than five business days after
such exercise of the option and, in any event, shall not be earlier than the
Firm Closing Date. The time and date set forth in such notice, or such other
time on such other date as the Representatives and the Company may agree upon or
as the Representatives may determine pursuant to Section 9 hereof, is herein
called the "Option Closing Date" with respect to such Option Securities. Upon
exercise of the option as provided herein, the Company shall become obligated to
sell to each of the several Underwriters, and, subject to the terms and
conditions herein set forth, each of the Underwriters (severally and not
jointly) shall become obligated to purchase from the Company the same percentage
of the total number of the Option Securities as to which the several
Underwriters are then exercising the option as such Underwriter is obligated to
purchase of the aggregate number of Firm Securities, as adjusted by the
Representatives in such manner as they deem advisable to avoid fractional
shares. If the option is exercised as to all or any portion of the Option
Securities, one or more certificates in definitive form for such Option
Securities, and payment therefor, shall be delivered on the related Option
Closing Date in the manner, and upon the terms and conditions, set forth in
paragraph (a) of this Section 3 and Schedule 1 to this Agreement, except that
reference therein to the Firm Securities and the Firm Closing Date shall be
deemed, for purposes of this paragraph (b), to refer to such Option Securities
and Option Closing Date, respectively.

                  (c) It is understood that any of you, individually and not as
one of the Representatives, may (but shall not be obligated to) make payment on
behalf of any Underwriter or Underwriters for any of the Securities to be
purchased by such Underwriter or Underwriters. No such payment shall relieve
such Underwriter or Underwriters from any of its or their obligations hereunder.

            4. Covenants of the Company. The Company covenants and agrees with
each of the Underwriters that:

                  (a) The Company will file the Prospectus or any Term Sheet
that constitutes a part thereof, any Integrated Prospectus or the Prospectus
Supplement, as the case may be, and any amendment or supplement thereto with the
Commission in the manner and within the time period required by Rules 434 and
424(b) under the Act. During any time when a prospectus relating to the
Securities is required to be delivered under the Act, the 


                                       16
<PAGE>

Company (i) will comply with all requirements imposed upon it by the Act and the
Exchange Act and the respective rules and regulations of the Commission
thereunder to the extent necessary to permit the continuance of sales of or
dealings in the Securities in accordance with the provisions hereof and of the
Prospectus and any Integrated Prospectus, as then amended or supplemented, and
(ii) will not file with the Commission the Prospectus, Term Sheet, any
Integrated Prospectus or any amendment or supplement thereto or any amendment to
the Registration Statement of which the Representatives shall not previously
have been advised and furnished with a copy for a reasonable period of time
prior to the proposed filing and as to which filing the Representatives shall
not have given their consent. The Company will prepare and file with the
Commission, in accordance with the rules and regulations of the Commission,
promptly upon request by the Representatives or counsel for the Underwriters,
any amendment to the Registration Statement or amendment or supplement to the
Prospectus and any Integrated Prospectus that may be necessary or advisable in
connection with the distribution of the Securities by the several Underwriters,
and will use its best efforts to cause any such amendment to the Registration
Statement to be declared effective by the Commission as promptly as possible.
The Company will advise the Representatives, promptly after receiving notice
thereof, of the time when any amendment to the Registration Statement has been
filed or declared effective or the Prospectus, any Integrated Prospectus or any
amendment or supplement thereto has been filed and will provide evidence
satisfactory to the Representatives of each such filing or effectiveness.

                  (b) The Company will advise the Representatives, promptly
after receiving notice or obtaining knowledge thereof, of (i) the issuance by
the Commission of any stop order suspending the effectiveness of the
Registration Statement or any post-effective amendment thereto or any order
directed at any document incorporated by reference in the Registration
Statement, the Prospectus or any Integrated Prospectus or any amendment or
supplement thereto or any order preventing or suspending the use of any
Preliminary Prospectus, the Prospectus or any Integrated Prospectus or any
amendment or supplement thereto, (ii) the suspension of the qualification of the
Securities for offering or sale in any jurisdiction, (iii) the institution,
threatening or contemplation of any proceeding for any such purpose or (iv) any
request made by the Commission for amending the Registration Statement, for
amending or supplementing any Preliminary Prospectus, the Prospectus or any
Integrated Prospectus or for additional information. The Company will use its
best efforts to prevent the issuance of any such stop order and, if any such
stop order is issued, to obtain the withdrawal thereof as promptly as possible.

                  (c) If required by applicable law, the Company will arrange
for the qualification of the Securities and any Underlying Securities for
offering and sale under the securities or blue sky laws of such jurisdictions as
the Representatives may designate and will 


                                       17
<PAGE>

continue such qualifications in effect for as long as may be necessary to
complete the distribution of the Securities and any Underlying Securities;
provided, however, that in connection therewith the Company shall not be
required to qualify as a foreign corporation or to execute a general consent to
service of process in any jurisdiction.

                  (d) If at any time when a prospectus relating to the
Securities is required to be delivered under the Act, any event occurs as a
result of which the Prospectus or any Integrated Prospectus, as then amended or
supplemented, would include any untrue statement of a material fact or omit to
state a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, or if for
any other reason it is necessary at any time to amend or supplement the
Prospectus or any Integrated Prospectus to comply with the Act or Exchange Act
or the respective rules or regulations of the Commission thereunder, the Company
will promptly notify the Representatives thereof and, subject to Section 4(a) of
this Agreement, will prepare and file with the Commission, at the Company's
expense, an amendment to the Registration Statement or an amendment or
supplement to the Prospectus and any Integrated Prospectus that corrects such
statement or omission or effects such compliance.

                  (e) The Company will, without charge, provide (i) to the
Representatives and to counsel for the Underwriters, a conformed copy of the
registration statement originally filed with respect to the Securities and any
amendment thereto (in each case including exhibits thereto), (ii) to each other
Underwriter, a conformed copy of such registration statement and any amendment
thereto relating to the Securities (in each case without exhibits thereto) and
(iii) so long as a prospectus relating to the Securities is required to be
delivered under the Act, as many copies of each Preliminary Prospectus, the
Prospectus or any Integrated Prospectus or any amendment or supplement thereto
as the Representatives may reasonably request; without limiting the application
of clause (iii) of this sentence, the Company, not later than (A) 6:00 p.m., New
York City time, on the date of determination of the public offering price, if
such determination occurred at or prior to 10:00 AM, New York City time, on such
date or (B) 12:00 Noon, New York City time, on the business day following the
date of determination of the public offering price, if such determination
occurred after 10:00 AM, New York City time, on such date, will deliver to the
Representatives, without charge, as many copies of the Prospectus or any
Integrated Prospectus and any amendment or supplement thereto as the
Representatives may reasonably request for purposes of confirming orders that
are expected to settle on the Firm Closing Date.

                  (f) The Company, as soon as practicable, will make generally
available to its securityholders and to the Representatives a consolidated
earning statement of the Company and its subsidiaries that satisfies the
provisions of Section 11(a) of the Act and 


                                       18
<PAGE>

Rule 158 thereunder.

                  (g) The Company will apply the net proceeds from the sale of
the Securities as set forth under "Use of Proceeds" in the Prospectus and any
Integrated Prospectus.

                  (h) Reserved.

                  (i) If required as set forth in Schedule 1 hereto, the Company
will obtain the agreements described in Section 6(g) hereof prior to the Firm
Closing Date.

                  (j) The Company will not, directly or indirectly, (i) take any
action designed to cause or to result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) (A) sell, bid for, purchase, or pay anyone any compensation
for soliciting purchases of the Securities or (B) pay or agree to pay to any
person any compensation for soliciting another to purchase any other securities
of the Company.

                  (k) If at any time during the 25-day period after the
Registration Statement becomes effective or the period prior to the Option
Closing Date, any rumor, publication or event relating to or affecting the
Company shall occur as a result of which in your opinion the market price of the
Common Stock has been or is likely to be materially affected (regardless of
whether such rumor, publication or event necessitates a supplement to or
amendment of the Prospectus or any Integrated Prospectus), the Company will,
after written notice from you advising the Company to the effect set forth
above, forthwith prepare, consult with you concerning the substance of, and
disseminate a press release or other public statement, reasonably satisfactory
to you, responding to or commenting on such rumor, publication or event.

                  (l) If required as set forth in Schedule 1 hereto, the Company
will cause the Securities and any Underlying Securities to be duly authorized
for listing by the New York Stock Exchange.

                  (m) The Company will continue to use its best efforts to meet
the requirements to qualify as a REIT under the Code.

            5. Expenses. The Company will pay all costs and expenses incident to
the performance of its obligations under this Agreement, whether or not the
transactions 


                                       19
<PAGE>

contemplated herein are consummated or this Agreement is terminated pursuant to
Section 10 hereof, including all costs and expenses incident to (i) the printing
or other production of documents with respect to the transactions, including any
costs of printing the registration statement originally filed with respect to
the Securities and any amendment thereto, any Preliminary Prospectus, the

the foregoing documents, (iii) the fees and disbursements of counsel,
accountants and any other experts or advisors retained by the Company, (iv)

Underwriters) and (ix) advertising relating to the offering of the Securities
requested by the Company (other than as shall have been specifically approved by
the Representatives to be paid for by the Underwriters). If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 6 of this Agreement is not
satisfied, because this Agreement is terminated pursuant to Section 10 of this
Agreement or because of any failure, refusal or inability on the part of the
Company to perform all obligations and satisfy all conditions on its part to be
performed or satisfied hereunder other than by reason of a default by and of the
Underwriters, the Company will reimburse the Underwriters severally upon demand
for all out-of-pocket expenses (including counsel fees and disbursements) that
shall have been incurred by them in connection with the proposed purchase and
sale of the Securities. The Company shall not in any event be liable to any of
the Underwriters for the loss of anticipated profits from the transactions
covered by this Agreement.

the Underwriters to purchase and pay for the Firm Securities shall be subject,

      and any Integrated Prospectus or the Prospectus Supplement, as the case
      may be, has been filed with the Commission in the manner and within the
      time period required by Rules 434 and 424(b); and no stop order suspending

      knowledge of such counsel, threatened by the Commission; and

                        (xix) the Registration Statement originally filed with
      respect to the Securities and each amendment thereto, the Prospectus and
      any Integrated Prospectus (in each case, including the documents
      incorporated by reference therein but not including the financial
      statements and other financial and statistical data contained therein, as
      to which such counsel need express no opinion) comply as to form in all
      material respects with the applicable requirements of the Act and the
      Exchange Act and the respective rules and regulations of the Commission
      thereunder.

            Such counsel shall also state that they have no reason to believe
that the Registration Statement, as of its effective date, contained any untrue
statement of a material fact or omitted to state any material fact required to
be stated therein or necessary to make the statements therein not misleading or
that the Prospectus or any Integrated Prospectus, as of the date of the
Prospectus Supplement or any required Integrated Prospectus and the date of such
opinion, included or includes any untrue statement of a material fact or omitted
or omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

            In rendering any such opinion, such counsel may rely, as to matters
of fact, to the extent such counsel deems proper, on certificates of responsible
officers of the Company and public officials and, as to matters involving the
application of laws of any jurisdiction other than the States of New York, New
Jersey and Delaware or the United States, to the extent satisfactory in form and
scope to counsel for the Underwriters, upon the opinion of local counsel. The
foregoing opinion shall also state that the Underwriters are justified in
relying upon such opinion of local counsel, and copies of such opinion shall be
delivered to the Representatives and counsel for the Underwriters.

            References to the Registration Statement, the Prospectus and any
Integrated 


                                       26
<PAGE>

Prospectus in this paragraph (b) shall include any amendment or supplement
thereto at the date of such opinion.

                  (c) The Representatives shall have received an opinion, dated
the Firm Closing Date, of Hunton & Williams, counsel for the Underwriters, with
respect to the issuance and sale of the Securities, the Registration Statement,
the Prospectus, and any Integrated Prospectus and such other related matters as
the Representatives may reasonably require, and the Company shall have furnished
to such counsel such documents as they may reasonably request for the purpose of
enabling them to pass upon such matters.

                  (d) The Representatives shall have received from Price
Waterhouse LLP and each other accounting firm that has certified financial
statements, and delivered its report with respect thereto, included or
incorporated by reference in the Registration Statement, the Prospectus and any
Integrated Prospectus, a letter or letters dated, respectively, the date of this
Agreement as specified in Schedule 1 hereto and the Firm Closing Date, in form
and substance satisfactory to the Representatives, to the effect that:

                        (i) they are independent accountants with respect to the
      Company and its subsidiaries within the meaning of the Act, the Exchange
      Act and the applicable published rules and regulations thereunder;

                        (ii) in their opinion, the financial statements audited
      by them and incorporated by reference in the Registration Statement, the
      Prospectus and any Integrated Prospectus comply as to form in all material
      respects with the applicable accounting requirements of the Act, the
      Exchange Act and the related published rules and regulations thereunder;

                        (iii) a reading of the minute books of the shareholders,
      the board of directors and any committees thereof of the Company and each
      of its consolidated subsidiaries, and inquiries of certain officials of
      the Company and its consolidated subsidiaries who have responsibility for
      financial and accounting matters, nothing came to their attention that
      caused them to believe that:

                        (A) (i) any unaudited consolidated condensed financial
                  statements of the Company and its consolidated subsidiaries
                  included in the Registration Statement, the Prospectus and any
                  Integrated Prospectus do not comply as to form in all material
                  respects with the applicable accounting requirements of the
                  Act, the Exchange Act and the related published rules and
                  regulations thereunder, or (ii) any material 


                                       27
<PAGE>

                  modification should be made to the unaudited consolidated
                  condensed financial statements for them to be in conformity
                  with generally accepted accounting principles;

                        (B) at a specific date not more than five business days
                  prior to the date of such letter, there were any changes in
                  the common stock or increase in mortgages and loans payable of
                  the Company and its consolidated subsidiaries, in each case
                  compared with amounts shown on the most recent consolidated
                  balance sheet included in the Registration Statement, the
                  Prospectus and any Integrated Prospectus, except for such
                  changes set forth in such letter;

                        (iv) they have carried out certain specified procedures,
      not constituting an audit, with respect to certain amounts, percentages
      and financial information that are derived from the general accounting
      records of the Company and its consolidated subsidiaries and are included
      in the Registration Statement, the Prospectus and any Integrated
      Prospectus and in Exhibit 12 to the Registration Statement, including the
      information included or incorporated in the Company's most recent Annual
      Report on Form 10-K under the captions "Business" (Item 1), "Selected
      Financial Data" (Item 6) and "Management's Discussion and Analysis of
      Financial Condition and Results of Operations" (Item 7) and the
      information included or incorporated in the Company's Quarterly Reports on
      Form 10-Q under the caption "Management's Discussion and Analysis of
      Financial Condition and Results of Operations," and have compared such
      amounts, percentages and financial information with such records and with
      information derived from such records and have found them to be in
      agreement, excluding any questions of legal interpretation; and

                        (v) on the basis of a reading of any unaudited pro forma
      consolidated condensed financial statements included in the Registration
      Statement, the Prospectus and any Integrated Prospectus, carrying out
      certain specified procedures that would not necessarily reveal matters of
      significance with respect to the comments set forth in this paragraph (v),
      inquiries of certain officials of the Company, its consolidated
      subsidiaries and any acquired company who have responsibility for
      financial and accounting matters and proving the arithmetic accuracy of
      the application of the pro forma adjustments to the historical amounts in
      the unaudited pro forma consolidated condensed financial statements,
      nothing came to their attention that caused them to believe that the
      unaudited pro forma consolidated condensed financial statements do not
      comply in form in all material respects with the applicable accounting
      requirements of Rule 11-02 of Regulation S-X or that the pro forma
      adjustments have 


                                       28
<PAGE>

      not been properly applied to the historical amounts in the compilation of
      such statements.

            In the event that the letters referred to above set forth any such
      changes, decreases or increases, it shall be a further condition to the
      obligations of the Underwriters that (A) such letters shall be accompanied
      by a written explanation of the Company as to the significance thereof,
      unless the Representatives deem such explanation unnecessary, and (B) such
      changes, decreases or increases do not, in the sole judgment of the
      Representatives, make it impractical or inadvisable to proceed with the
      purchase and delivery of the Securities as contemplated by the
      Registration Statement.

            References to the Registration Statement, the Prospectus and any
      Integrated Prospectus in this paragraph (d) with respect to either letter
      referred to above shall include any amendment or supplement thereto at the
      date of such letter.

                  (e) The Representatives shall have received a certificate,
dated the Firm Closing Date, of the chief executive officer and the chief
financial or accounting officer of the Company to the effect that:

                        (i) the representations and warranties of the Company in
      this Agreement are true and correct as if made on and as of the Firm
      Closing Date; the Registration Statement, as amended as of the Firm
      Closing Date, does not include any untrue statement of a material fact or
      omit to state any material fact necessary to make the statements therein
      not misleading, and the Prospectus or any Integrated Prospectus, as
      amended or supplemented as of the Firm Closing Date, does not include any
      untrue statement of a material fact or omit to state any material fact
      necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading; and the Company
      has performed all covenants and agreements and satisfied all conditions on
      its part to be performed or satisfied at or prior to the Firm Closing
      Date;

                        (ii) no stop order suspending the effectiveness of the
      Registration Statement or any post-effective amendment thereto and no
      order directed at any document incorporated by reference in the
      Registration Statement, the Prospectus or any Integrated Prospectus or any
      amendment or supplement thereto has been issued, and no proceedings for
      that purpose have been instituted or threatened or, to the best of the
      Company's knowledge, are contemplated by the Commission; and


                                       29
<PAGE>

                        (iii) subsequent to the respective dates as of which
      information is given in the Registration Statement, the Prospectus and any
      Integrated Prospectus, neither the Company nor any of its subsidiaries has
      sustained any material loss or interference with their respective
      businesses or properties from fire, flood, hurricane, accident or other
      calamity, whether or not covered by insurance, or from any labor dispute
      or any legal or governmental proceeding, and there has not been any
      material adverse change, or any development involving a prospective
      material adverse change, in the condition (financial or otherwise),
      management, business prospects, net worth or results of operations of the
      Company or any of its subsidiaries, except in each case as described in or
      contemplated by the Prospectus or any Integrated Prospectus (exclusive of
      any amendment or supplement thereto).

                  (f) On or before the Firm Closing Date, the Representatives
and counsel for the Underwriters shall have received such further certificates,
documents or other information as they may have reasonably requested from the
Company.

                  (g) Reserved.

                  (h) If applicable, prior to the commencement of the offering
of the Securities, the Securities and any Underlying Securities shall have been
approved for listing on the New York Stock Exchange, subject to official notice
of issuance.

            All opinions, certificates, letters and documents delivered pursuant
to this Agreement will comply with the provisions hereof only if they are
reasonably satisfactory in all material respects to the Representatives and
counsel for the Underwriters. The Company shall furnish to the Representatives
such conformed copies of such opinions, certificates, letters and documents in
such quantities as the Representatives and counsel for the Underwriters shall
reasonably request.

            The respective obligations of the several Underwriters to purchase
and pay for any Option Securities shall be subject, in their discretion, to each

refer to such Option Securities and the related Option Closing Date,
respectively.

            7. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter 


                                       30
<PAGE>

or such controlling person may become subject under the Act, the Exchange Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon:

                        (i) any untrue statement or alleged untrue statement
      made by the Company in Section 2 of this Agreement,

                        (ii) any untrue statement or alleged untrue statement of
      any material fact contained in (A) the Registration Statement or any
      amendment thereto or any Preliminary Prospectus, the Prospectus or any
      Integrated Prospectus or any amendment or supplement thereto or (B) any
      application or other document, or any amendment or supplement thereto,
      executed by the Company or based upon written information furnished by or
      on behalf of the Company filed in any jurisdiction in order to qualify the
      Securities under the securities or blue sky laws thereof or filed with the
      Commission or any securities association or securities exchange (each an
      "Application"),

                        (iii) the omission or alleged omission to state in the
      Registration Statement or any amendment thereto, any Preliminary
      Prospectus, the Prospectus or any Integrated Prospectus or any amendment
      or supplement thereto, or any Application a material fact required to be
      stated therein or necessary to make the statements therein not misleading
      or

                        (iv) any untrue statement or alleged untrue statement of
      any material fact contained in any audio or visual materials used in
      connection with the marketing of the Securities, including, without
      limitation, slides, videos, films and tape recordings,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in such registration statement or
any amendment thereto, any Preliminary Prospectus, the Prospectus or any
Integrated Prospectus or any amendment or supplement thereto, or any Application

Company by such Underwriter through the Representatives specifically for use
therein. This indemnity agreement will be in addition to any liability 


                                       31
<PAGE>

which the Company may otherwise have. The Company will not, without the prior
written consent of the Underwriter or Underwriters purchasing, in the aggregate,
more than 50% of the Firm Securities, settle or compromise or consent to the
entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not any such Underwriter or any person who controls any such Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is
a party to such claim, action, suit or proceeding), unless such settlement,
compromise or consent includes an unconditional release of all of the
Underwriters and such controlling persons from all liability arising out of such
claim, action, suit or proceeding.

                  (b) Each Underwriter, severally and not jointly, will
indemnify and hold harmless the Company, each of its directors, each of its
officers who signed the Registration Statement, as amended at the date of this
Agreement as specified in Schedule 1 hereto, and each person, if any, who
controls the Company within the meaning of Section 15 of the Act or Section 20
of the Exchange Act against any losses, claims, damages or liabilities to which
the Company or any such director, officer or controlling person may become
subject under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement, as amended at the date of this Agreement as
specified in Schedule 1 hereto, any Preliminary Prospectus, the Prospectus or
any Integrated Prospectus or any amendment or supplement thereto, or any
Application or (ii) the omission or the alleged omission to state therein a
material fact required to be stated in the Registration Statement, as amended at
the date of this Agreement as specified in Schedule 1 hereto, any Preliminary
Prospectus, the Prospectus or any Integrated Prospectus or any amendment or
supplement thereto, or any Application or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through the Representatives
specifically for use therein; and, subject to the limitation set forth
immediately preceding this clause, will reimburse, as incurred, any legal or
other expenses reasonably incurred by the Company or any such director, officer
or controlling person in connection with investigating or defending any such
loss, claim, damage, liability or any action in respect thereof. This indemnity
agreement will be in addition to any liability which such Underwriter may
otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 7, notify the indemnifying party of the commencement thereof;
but the omission so to notify the 


                                       32
<PAGE>

indemnifying party will not relieve it from any liability which it may have to
any indemnified party otherwise than under this Section 7. In case any such
action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party; provided, however,
that if the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or parties
and such indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or parties.
After notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof and approval by such indemnified party
of counsel appointed to defend such action, the indemnifying party will not be
liable to such indemnified party under this Section 7 for any legal or other
expenses, other than reasonable costs of investigation, subsequently incurred by
such indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that in
connection with such action the indemnifying party shall not be liable for the
expenses of more than one separate counsel (in addition to local counsel) in any
one action or separate but substantially similar actions in the same
jurisdiction arising out of the same general allegations or circumstances,
designated by the Representatives in the case of paragraph (a) of this Section
7, representing the indemnified parties under such paragraph (a) who are parties
to such action or actions) or (ii) the indemnifying party does not promptly
retain counsel satisfactory to the indemnified party or (iii) the indemnifying
party has authorized the employment of counsel for the indemnified party at the
expense of the indemnifying party. After such notice from the indemnifying party
to such indemnified party, the indemnifying party will not be liable for the
costs and expenses of any settlement of such action effected by such indemnified
party without the consent of the indemnifying party.

                  (d) In circumstances in which the indemnity agreement provided
for in the preceding paragraphs of this Section 7 is unavailable or
insufficient, for any reason, to hold harmless an indemnified party in respect
of any losses, claims, damages or liabilities (or actions in respect thereof),
each indemnifying party, in order to provide for just and equitable
contribution, shall contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities (or actions in
respect thereof) in such proportion as is appropriate to reflect (i) the
relative benefits received by the indemnifying party or parties on the one hand
and the indemnified party on the other from the offering of 


                                       33
<PAGE>

the Securities or (ii) if the allocation provided by the foregoing clause (i) is
not permitted by applicable law, not only such relative benefits but also the
relative fault of the indemnifying party or parties on the one hand and the
indemnified party on the other in connection with the statements or omissions or
alleged statements or omissions that resulted in such losses, claims, damages or
liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative benefits received by the Company on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total proceeds from the offering (before deducting expenses)
received by the Company bear to the total underwriting discounts and commissions
received by the Underwriters. The relative fault of the parties shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company or the
Underwriters, the parties' relative intents, knowledge, access to information
and opportunity to correct or prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances. The Company and the
Underwriters agree that it would not be equitable if the amount of such
contribution were determined by pro rata or per capita allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation that does not take into account the equitable considerations
referred to above in this paragraph (d). Notwithstanding any other provision of
this paragraph (d), no Underwriter shall be obligated to make contributions
hereunder that in the aggregate exceed the total public offering price of the
Securities purchased by such Underwriter under this Agreement, less the
aggregate amount of any damages that such Underwriter has otherwise been
required to pay in respect of the same or any substantially similar claim, and
no person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations to
contribute hereunder are several in proportion to their respective underwriting
obligations and not joint. For purposes of this paragraph (d), each person, if
any, who controls an Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act shall have the same rights to contribution as
such Underwriter, and each director of the Company, each officer of the Company
who signed the Registration Statement as amended at the date of this Agreement
as specified in Schedule 1 hereto and each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act, shall have the same rights to contribution as the Company.

            8. Default of Underwriters. If one or more Underwriters default in
their obligations to purchase Firm Securities or Option Securities hereunder and
the aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other 


                                       34
<PAGE>

Underwriters may make arrangements satisfactory to the Representatives for the
purchase of such Securities by other persons (who may include one or more of the
non-defaulting Underwriters, including the Representatives), but if no such
arrangements are made by the Firm Closing Date or the related Option Closing
Date, as the case may be, the other Underwriters shall be obligated severally in
proportion to their respective commitments hereunder to purchase the Firm
Securities or Option Securities that such defaulting Underwriter or Underwriters
agreed but failed to purchase. If one or more Underwriters so default with
respect to an aggregate number of Securities that is more than ten percent of
the aggregate number of Firm Securities or Option Securities, as the case may
be, to be purchased by all of the Underwriters at such time hereunder, and if
arrangements satisfactory to the Representatives are not made within 36 hours
after such default for the purchase by other persons (who may include one or
more of the non-defaulting Underwriters, including the Representatives) of the
Securities with respect to which such default occurs, this Agreement will
terminate without liability on the part of any non-defaulting Underwriter or the
Company other than as provided in Section 9 hereof. In the event of any default
by one or more Underwriters as described in this Section 8, the Representatives
shall have the right to postpone the Firm Closing Date or the Option Closing
Date, as the case may be, established as provided in Section 3 of this Agreement
for not more than seven business days in order that any necessary changes may be
made in the arrangements or documents for the purchase and delivery of the Firm
Securities or Option Securities, as the case may be. As used in this Agreement,
the term "Underwriter" includes any person substituted for an Underwriter under
this Section 8. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

            9. Survival. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, its officers and the
several Underwriters set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the Company,
any of its officers or directors, any Underwriter or any controlling person
referred to in Section 7 hereof and (ii) delivery of and payment for the
Securities. The respective agreements, covenants, indemnities and other
statements set forth in Sections 5 and 7 hereof shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement.

            10. Termination. (a) This Agreement may be terminated with respect
to the Firm Securities or any Option Securities in the sole discretion of the
Representatives by notice to the Company given prior to the Firm Closing Date or
the related Option Closing Date, respectively, in the event that the Company
shall have failed, refused or been unable to perform all obligations and satisfy
all conditions on its part to be performed or satisfied 


                                       35
<PAGE>

hereunder at or prior thereto or, if at or prior to the Firm Closing Date or
such Option Closing Date, respectively,

                        (i) the Company or any of the Subsidiaries shall have,
      in the sole judgment of the Representatives, sustained any material loss
      or interference with their respective businesses or properties from fire,
      flood, hurricane, accident or other calamity, whether or not covered by
      insurance, or from any labor dispute or any legal or governmental
      proceeding or there shall have been any material adverse change, or any
      development involving a prospective material adverse change (including
      without limitation a change in management or control of the Company, which
      includes the termination of the employment of Thomas A. Rizk), in the
      condition (financial or otherwise), business prospects, net worth or
      results of operations of the Company and the Subsidiaries, except in each
      case as described in or contemplated by the Prospectus (exclusive of any
      amendment or supplement thereto);

                        (ii) trading in the Common Stock shall have been
      suspended by the Commission or the New York Stock Exchange or trading in
      securities generally on the New York Stock Exchange shall have been
      suspended or minimum or maximum prices shall have been established on such
      exchange;

                        (iii) there shall have been any downgrading in the
      rating of any debt securities or preferred stock of the Company by any
      "nationally recognized statistical rating organization" (as defined for
      purposes of Rule 436(g) under the Act), or any public announcement that
      any such organization has under surveillance or review its rating of any
      debt securities or preferred stock of the Company (other than an
      announcement with positive implications of a possible upgrading, and no
      implication of a possible downgrading, of such rating);

                        (iv) a banking moratorium shall have been declared by
      New York or United States authorities; or

                        (v) there shall have been (A) an outbreak or escalation
      of hostilities between the United States and any foreign power, (B) an
      outbreak or escalation of any other insurrection or armed conflict
      involving the United States or (C) any other calamity or crisis or
      material adverse change in general economic, political or financial
      conditions having an effect on the U.S. financial markets that, in the
      sole judgment of the Representatives, makes it impractical or inadvisable
      to proceed with the public offering or the delivery of the Securities as
      contemplated by the Registration Statement, as amended at the date of this
      Agreement as specified in Schedule 1 hereto


                                       36
<PAGE>

                  (b) Termination of this Agreement pursuant to this Section 10
shall be without liability of any party to any other party except as provided in
Section 9 hereof.

            11. Information Supplied by Underwriters. The statements set forth
in the last paragraph on the front cover page of the Prospectus Supplement and
under the heading "Underwriting" in the Prospectus Supplement (to the extent
such statements relate to the Underwriters) constitute the only information
furnished by any Underwriter through the Representatives to the Company for the
purposes of Sections 2(b) and 7(b) hereof. The Underwriters confirm that such
statements (to such extent) are correct.

            12. Notices. All communications hereunder shall be in writing and,
if sent to any of the Underwriters, shall be delivered or sent by mail, telex or

shall be binding upon the several Underwriters, the Company and their respective
successors and legal representatives, and nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any other person any legal
or equitable right, remedy or claim under or in respect of this Agreement, or
any provisions herein contained, this Agreement and all conditions and
provisions hereof being intended to be and being for the sole and exclusive
benefit of such persons and for the benefit of no other person except that (i)
the indemnities of the Company contained in Section 7 of this Agreement shall
also be for the benefit of any person or persons who control any Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act

Agreement shall also be for the benefit of the directors of the Company, the
officers of the Company who have signed the Registration Statement as amended at
the date of this Agreement as specified in Schedule 1 hereto and any person or
persons who control the Company within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act. No purchaser of Securities from any Underwriter
shall be deemed a successor because of such purchase.

            14. Applicable Law. THE VALIDITY AND INTERPRETATION OF THIS
AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS 


                                       37
