              CAREY DIVERSIFIED LLC TO MERGE WITH W. P. CAREY & CO.


                 WILL CREATE NATION'S DOMINANT NET LEASE COMPANY


NEW YORK, November 30, 1999 - Carey Diversified LLC (NYSE: CDC) today announced
that its Board of Directors has unanimously approved a merger with W. P. Carey &
Co, Inc. ("W. P. Carey"). W. P. Carey is a real estate investment firm which
manages a group of companies, including the Corporate Property Associates series
of private REITs, Carey Institutional Properties and Carey Diversified LLC. If
approved by the shareholders of Carey Diversified, assets under ownership or
management will increase from $750 million to approximately $2.5 billion post
merger. As a result, the merged entity ("WPC" or the "Company") will be a fully
integrated investment company and the nation's dominant net lease firm.

The Company expects to be listed on the New York Stock Exchange and the Pacific
Stock Exchange under the symbol "WPC." The combined business will be renamed W.
P. Carey & Co. LLC to capitalize on the strong corporate identity that W. P.
Carey has built among its clients and the investment community over the last 26
years. W. P. Carey personnel will become employees of the Company. All of the
operations of W. P. Carey & Co., Inc. will be contributed in exchange for 8
million shares of WPC. W. P. Carey stockholders may earn up to 2 million
additional shares of the Company over a period of up to five years, based upon
certain performance criteria.

Carey Diversified's Board believes the proposed merger will significantly
enhance shareholder value through:

         -        IMMEDIATE ACCRETION - Expected to be accretive to the
                  company's per share FFO during the first year of combined
                  operations and more accretive thereafter;

         -        UNIQUE ACCESS TO CAPITAL - Capitalize on W. P. Carey's access
                  to private equity;

         -        ENHANCED GROWTH - Add the greater growth potential of W. P.
                  Carey's asset management business to the stability of CDC's
                  net lease investment revenues;

         -        STRENGTHENED CREDIT PROFILE - By acquiring W. P. Carey without
                  indebtedness, the financial ratios and flexibility of the
                  company will improve; and

         -        FUTURE GROWTH POTENTIAL - Leverage the Company's solid brand
                  image to provide new means of growth in the future.



William P. Carey will be the Chairman and Chief Executive Officer of the
combined Company. Gordon F. DuGan and John J. Park will continue to serve as
President and Chief Financial Officer, respectively. Francis J. Carey will
become Vice Chairman and remain on the Board.

William P. Carey, Chairman and Chief Executive Officer of W. P. Carey & Co.,
Inc. stated, "When a prominent securities analyst called W. P. Carey a 'bet on
brains,' he captured my vision for a Company built on talent, ambition and
innovation, but that is only part of the story. Our team is gifted and highly
motivated and, working within the framework of our long-term philosophy, will
continue to build value for our shareholders. I chose to take shares in WPC in
the merger because I believe in the future of this enterprise."

Carey Diversified's President, Gordon F. DuGan, stated, "We are merging in order
to provide our shareholders with the best of both worlds - stable income from
the net lease business and growth from the asset management business. We believe
strongly that the company resulting from this merger will be
   3
uniquely positioned to leverage our access to capital in the private markets to
generate superior shareholder returns."

directors to review and evaluate the potential merger. The special committee
retained Hogan & Hartson LLP as legal counsel and Robert A. Stanger & Co. as

McClay. It is anticipated that consent solicitation statements will be mailed to
shareholders in January 2000. Subject to shareholder approval of the merger, it
is expected that the transaction will close in second quarter of 2000.
