EQUITY OFFICE PROPERTIES TRUST AND CORNERSTONE PROPERTIES INC. ANNOUNCE MERGER
AGREEMENT
$4.6 Billion Transaction to Create $18 Billion Office Company
Combined Organization to Own And Operate 95.5 Million Square Feet of Premier
Office Space Nationwide
CHICAGO, and NEW YORK, Feb. 11 /PRNewswire/ -- Equity Office Properties Trust
(NYSE: EOP) and Cornerstone Properties Inc. (NYSE: CPP) today announced that
they have entered into a definitive plan of merger in which Cornerstone will
merge into Equity Office. Once the merger is completed, Equity Office will
own and operate 380 office buildings consisting of 95.5 million square feet
nationwide, a 24% increase in portfolio size based on square footage.
"This merger captures for shareholders of both entities the true benefits of
consolidation in our industry," said Samuel Zell, chairman of the board of
Equity Office. "Cornerstone's properties represent unsurpassed asset quality
concentrated in high barrier-to-entry markets with some of the strongest job
growth rates in the country fueled by the explosive growth in high tech
industries."
<PAGE>
Timothy H. Callahan, president and chief executive officer of Equity Office,
added, "In addition to increasing the diversification and liquidity of the
combined portfolio, these assets are a perfect complement to existing Equity
Office geographic locations. More than 12.5 million square feet (approximately
two-thirds of Cornerstone's portfolio) are in Equity Office's top eight core
markets. Combined, we can offer our customers an unsurpassed range of office
space options and the highest quality services." Mr. Callahan also said that
"Equity Office expects the transaction to be modestly accretive in 2000 and
three to five cents accretive in 2001. Furthermore, the yields on the
transaction in the first 12 months, including all transaction costs, are
expected to be approximately 9.5% on a GAAP basis, 9% on a cash basis and 8.7%
for EBITDA (excluding straight line rent)."
The transaction values Cornerstone at approximately $4.6 billion, which includes
transaction costs and the assumption of approximately $1.8 billion of debt.
Equity Office will pay approximately $1.1 billion in cash and issue
approximately 63.6 million new Equity Office common shares and operating
partnership units in the transaction. Cornerstone common shareholders may elect
to receive $18.00 per share in cash or 0.7009 of an Equity Office common share
or a combination thereof, subject to a final proration. The proportion of
consideration would be approximately 55% shares and 45% cash to the common
shareholder if all current holders of units of Cornerstone Properties Limited
Partnership elect to receive units in EOP Operating Limited Partnership.
Cornerstone common shares will be exchanged for Equity Office common shares at a
fixed 0.7009 exchange ratio based on a prevailing transaction price of $25.68125
per Equity Office common share. The exchange ratio is not subject to change
based on changes in the market prices of either company's common shares, and
there is no "collar" or minimum trading price for the shares. Cornerstone
Properties Limited Partnership unit holders will receive 0.7009 EOP Operating
Limited Partnership units per Cornerstone unit. Cornerstone's convertible
preferred shareholders will receive $18.00 per share in cash.
Equity Office expects to arrange a new credit facility of approximately $1.5
billion to finance a portion of the cash consideration. Equity Office is
currently in discussion with its lead lenders with a view towards obtaining such
financing.
Upon completion of the merger, Equity Office will expand its Board of Trustees
from 11 to 14 members. The new members will be John S. Moody, president and
chief executive officer of Cornerstone, Jan H. W. R. van der Vlist, director of
real estate for PGGM, and William Wilson III, chairman of Cornerstone's Board of
Directors.
The transaction is structured in order to qualify as a tax-free merger, and it
is a condition to closing that each party receive an acceptable tax opinion to
that effect. Shareholders receiving cash will recognize income for federal
income tax purposes.
"The strategic merits of this merger include not only the quality of
Cornerstone's assets and people, but also their commitment to superior customer
service. In addition, we look forward to combining the development capabilities
of our two organizations to take advantage of strategic opportunities for growth
in many of today's most supply-constrained markets, such as San Francisco and
Seattle," said Callahan. "Cornerstone will bring to Equity Office its top-tier
development team and a pipeline that we expect to add to our future growth rate.
It is among our highest priorities to determine how we can best take full
<PAGE>
advantage of the opportunities available to us as a result of Cornerstone's
development team," said Mr. Callahan.
"Cornerstone is extremely pleased to become part of the highest quality office
REIT in the U.S. We believe that the benefits for our shareholders will be
dramatic as we capitalize on the benefits of greater scale, liquidity, and
market leadership," said John S. Moody, president and chief executive officer of
Cornerstone Properties.
The merger, which will be accounted for using purchase accounting, is expected
to be completed in the third quarter of 2000, and is subject to the approval of
the shareholders of both companies and other customary conditions.
PGGM, a 30% shareholder in Cornerstone, and the Directors and certain executive
officers of both companies have agreed to vote in favor of the merger as part of
the merger agreement.
J.P. Morgan & Co. Incorporated was lead financial advisor to Equity Office and
provided a fairness opinion to the Company. Bank of America Securities, Inc. and
Chase Securities, Inc. were co-advisors to Equity Office. Lazard Freres & Co.
was financial advisor to Cornerstone.
As a result of today's announcement, Equity Office has elected to suspend
immediately its previously announced share buy-back program, until further
notice.
Certain matters discussed in this press release may constitute forward- looking
statements within the meaning of the Federal Securities laws. Although Equity
Office and Cornerstone believe that the expectations reflected in such
forward-looking statements are based upon reasonable assumptions, they can give
no assurance that their expectations will be achieved. Factors that could cause
actual results to differ materially from current expectations include an
increase in market interest rates, the availability of adequate financing on
acceptable terms, the ability of the merged company to realize synergies and
efficiencies as a result of its increased size and presence in certain markets,
future real estate and general market conditions, the extent of future revenues
and expense attributed to the merged company's portfolio, the extent of future
tenant demand for office space, the companies' respective abilities to satisfy
all conditions for closing including the availability of opinions confirming the
transaction's tax-free status and other risks detailed from time to time in the
companies' respective filings with the Securities and Exchange Commission,
including their annual reports on Form 10-K.
