New York, NEW YORK (February 25, 1999) -- Cornerstone Properties Inc. (NYSE:
CPP), a real estate investment trust, announced today results for its fourth
quarter ended December 31, 1998. Funds from operations (FFO) allocated to
share/unit holders amounted to $43,285,000, or $0.37 per share/unit calculated
on 117,272,000 average diluted total shares/units outstanding, compared to
$26,163,000, or $0.34 per share/unit on 77,676,000 average diluted total
shares/units outstanding for the three months ended December 31, 1997. The
increase in FFO per share/unit was due to the accretive impact of the Companys
acquisitions over the past twelve months and internal growth. As defined by
NAREIT, funds from operations is net income excluding expenses from debt
restructuring, gains (or losses) on sale of property, plus depreciation and
amortization.
Year-to-date net operating income before depreciation from Cornerstone
Properties real estate assets increased 136% to $231,553,000 for the 12 months
ended December 31, 1998, from $98,306,000 for the comparable period in 1997.

$15,881,000 in the fourth quarter of 1997. Year-to-date net income increased to

<PAGE>
Quarterly Dividend Declared
The Company declared a quarterly dividend of $0.30 per share based on two record
dates. A distribution of $0.15 was declared for all shareholders of record as of
December 15, 1998 to be paid on February 26, 1999. A second distribution of
$0.15 was declared for all shareholders of record as of January 29, 1999 and
will also be paid on February 26, 1999. The two separate payments are being made
pursuant to the merger between Cornerstone Properties Inc. and William Wilson &
Associates.
Same Store Revenue Growth Continues
The Company achieved year-to-date same store
net operating income growth of
3.0% over 1997 at the seven properties owned over the same period; this compares
favorably to the 0.93% achieved during the same period in 1997. This increase is
due to a 2.19% increase in revenues while expenses increased only 0.88% and
reflects the strengthening of fundamentals in the Companys core markets.
Leasing Update: Tenant Retention Rate 76% and Overall Occupancy Rate 95%
Tenant retention for 1998 was a very strong 76%. The portfolios overall
occupancy rate currently stands at 95%.
Closure of $1.8 Billion Merger with William Wilson and Associates

addition to serving as Chairman of the Board of Directors, Mr. Wilson will serve
as President of Wilson Cornerstone Properties, the western operating division of
Cornerstone. Following the closing, Cornerstone owns a national portfolio of
Class A real estate totaling approximately 21 million square feet and ranks
among the top four office REITs in the United States.
Awarded development rights to the historic Ferry Building
Cornerstone announced on November 19, 1998 that the Cornerstone development team

general office space.

$350 million to $550 million and the term was extended through November 3, 2001.

Tenant Retention Schedule
As of December 31, 1998
- --------------------------------------------------------------------------------
The attached table sets forth the Company's tenant retention on expiring leases
since January 1, 1994. The analysis is based upon the percentage of expiring
leases in the applicable building with a tenant or subtenant being retained in
the expiring space, or an existing tenant expanding into the expiring space. A
tenant's lease is added to the retention schedule at the time a lease extension
is signed with the tenant, or the tenant notifies the Company of an option being
exercised.

(1)1996 and 1997 leasing and capital costs have been restated to reflect
the 1998 sale of the Frick Building.
---------------------------------------------------------------------------
The following table shows Historical Non-Incremental Revenue Generating
Leasing Costs, which are the leasing costs (tenant improvements and leasing
commissions), in total and on a per square foot basis, to re-lease expiring
leases or renew or extend existing leases. The Company believes that its
ability to renew and extend existing tenants at a high percentage has
substantially reduced its overall leasing costs on a per square foot basis.
Additionally, the table shows Historical Non-Incremental Revenue Generating
Capital Expenditures, which are Capital Expenditures expended to maintain a
property in a Class A manner and do not give rise to additional earnings
capacity, but rather allow the property to maintain its competitive
position within its market. The Company believes that its focus on
continuing high level of maintenance of its assets has greatly reduced the
amount of Capital Expenditures required at its buildings.

commissions) required to lease (i) first generation space on development
properties and (ii) space which was vacant at the time of the acquisition
of a property which will increase the overall return on the property.
Additionally, the table shows Historical Incremental Revenue Generating
Capital Expenditures, which are Capital Expenditures expended to increase
the profitability of the building either through the generation of higher
earnings capability, or by improving building system efficiency, thus
producing lower operating expenses prospectively.

o Minority Sharing in Cash Flows and
Residual Proceeds
<PAGE>
Minority Sharing in Cash Flows and Residual Proceeds
Seven of the Company's properties are held in partnerships which allow the
Company's partners to participate in the cash flows of their respective
properties. The following discussion provides the details of partner's
participation in the cash flow of each of the respective properties.
Norwest Center
Under the partnership agreement, cash flow is used first to pay operating
and capital expenditures, then debt service on the mortgage note. The remaining
cash flow is paid first to Cornerstone, as a 7% cumulative preference return on
its capital base of $92.3 million ($6,461,000), and then any remaining cash flow
is split 50% to Cornerstone and 50% to their partner, Sixth & Marquette Limited
Partnership ("S&M"). Should cash flow be insufficient to pay the preference
return ("Preference Deficit"), it will accumulate and earn interest at 7%. Any
Preference Deficit will be paid as the first priority payment after debt
service. Cash flow and earnings for the twelve months of 1998 were split 77.9%
to Cornerstone and 22.1% to S&M. Sales proceeds from Norwest Center will be
split as follows as of December 31, 1998:
1) To Debt $110.0 million
2) To Cornerstone 92.3 million
3) To Cornerstone 9.3 million
4) To Cornerstone 1.0 million
5) To S&M 19.5 million
6) The remaining proceeds will be split 50/50 among the two partners.
Washington Mutual Tower
Under the partnership agreement, cash flow is used first to pay operating
and capital expenditures, then debt service on the mortgage note. The remaining
cash flow is paid first to Cornerstone as a 9.53% preference return on its
capital base of $47.0 million ($4,479,000); next to pay the Preference Deficit
on the second preference return (currently $9.0 million); then to Cornerstone as
an 8% second preference return on its capital base of $100.0 million
($8,000,000). Any remaining cash flow is split 50% to Cornerstone and 50% to
1212. The cumulative Preference Deficit earns interest at a rate of 8% until it
is repaid. Cornerstone's partner, 1212 Partnership, does not currently share in
the cash flow from Washington Mutual Tower. With regard to the sale of the
building, the Company will receive the first $156.0 million of proceeds after
repayment of the $79.1 million mortgage ($235.1 million in total proceeds). Any
proceeds above this amount will be split 50/50 with Cornerstone's partners.

Minority Sharing in Cash Flows and Residual Proceeds (continued)
191 Peachtree Street
Under the partnership agreement, cash flow is used first to pay operating
and capital expenditures, then debt service on the mortgage note. In addition,
the partner in the transaction, CH Associates, Ltd., will receive an annual
incentive distribution of $250,000 which Cornerstone expects it will receive
under the partnership agreement through February 28, 2000. Cornerstone receives
the remaining cash flow until such time as its cumulative undistributed
preferred return ($162.9 million as of 12/31/98) has been reimbursed. Excess
cash flow will be split 80% to Cornerstone and 20% to CH Associates, Ltd. Sales
proceeds from 191 Peachtree Street will be split as follows as of December 31,
1998:
1) To Debt $ 1.8 million
2) To Cornerstone (as partial holder of the debt) $159.0 million
3) To Cornerstone for its undistributed preferred return $ 17.9 million
4) To Cornerstone for its priority capital contribution $145.0 million
