Item 5.           Other Items
                  -----------

On June 4, 2004, Carey Institutional Properties Incorporated ("CIP(R)") and
Corporate Property Associates 15 Incorporated ("CPA(R):15"), two publicly held,
non-traded REITs managed by the Company, entered into an Agreement and Plans of
Merger (the "Merger Agreement"), whereby CPA(R):15 will acquire most of the
properties of CIP(R) in exchange for CPA(R):15 common stock and cash. The
transaction is subject to the approval of a two-thirds majority of the CIP(R)
shareholders and a majority of the CPA(R):15 shareholders. CIP(R) and CPA(R):15
have filed a joint proxy statement/registration statement with the Securities
and Exchange Commission with respect to the transaction. Each shareholder of
CIP(R) as of the date of the Merger Agreement will receive a special
distribution of $3.00 per share and will have the option to receive either 1.09
shares of CPA(R):15 or $10.90 in cash for each share of CIP(R) stock they own.

In connection with this transaction, and conditioned upon the approval of the
transaction by the shareholders of the constituent companies, the Company will
acquire 17 properties from CIP(R). These properties are being acquired for a
purchase price of approximately $114 million in cash, plus the assumption of $28
million of debt. The 17 properties have lease expirations of less than 8 years.
The purchase price for these properties was established by third party
appraisals.

Upon consummation of the transaction, the Company will receive a subordinated
disposition fee from CIP(R) in the amount of approximately $22,656,000 and a
subordinated incentive fee in the amount of $23,681,223. These fees are being
paid pursuant to the existing advisory agreement between the Company and CIP(R).
The Company will also receive an acquisition fee from CPA(R):15 to the extent
cash is used to acquire properties from CIP(R). The amount of the fee will
approximate the fee that would be payable if the properties were being acquired
from unaffiliated third parties.

In addition, upon completion of the transaction, the Company has agreed to
indemnify CPA(R):15 against and from certain damages, up to $5,000,000,
sustained or incurred resulting from or arising out of or by virtue of CIP(R)'s
or CPA(R):15's ownership of the real properties acquired by CPA(R):15 from
CIP(R) relating to a defect in the condition of or title to such real property
known by the Company as of the date of the closing of the transaction, and such
defect was not disclosed by any party to the Merger Agreement and was required
to be disclosed pursuant to the terms of the Merger Agreement.
