                                   (Unaudited)

NOTE 1- ORGANIZATION

     Chastain Capital Corporation (the "Company") was incorporated in Georgia on
December 16, 1997 and was initially capitalized on such date through the sale of
100 shares of Common Stock for an aggregate purchase price of $1,000. The
Company will seek to originate commercial and multifamily mortgage loans
("Mortgage Loans") for the purpose of issuing collateralized mortgage
obligations ("CMOs") collateralized by its Mortgage Loans and retaining the
Mortgage Loans subject to the CMO debt. As a result of such transactions, the
Company will retain a "first loss" subordinated equity ownership interest in the
Mortgage Loans that has economic characteristics similar to those of
subordinated interests in commercial mortgage-backed securities ("CMBS"). The
Company also intends to acquire subordinated interests in CMBS, originate and
acquire investments in real property that are subordinated to first lien
Mortgage Loans ("Mezzanine Investments") and acquire real property and other
real estate related assets.

     Through March 31, 1998, the Company had no operations.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

     The consolidated financial statements of the Company include the accounts
of the Company and its wholly owned subsidiaries. All material intercompany
accounts have been eliminated in consolidation.

Income Taxes

     The Company is organized as a real estate investment trust ("REIT") under
Sections 856-860 of the Internal Revenue Code of 1986, as amended. As a REIT,
the Company must distribute to its shareholders at least 95% of its taxable
income and is not subject to federal income tax to the extent income is
distributed.

Income Recognition

     Income and expenses are to be recorded on the accrual basis of accounting.

NOTE 3 - SUBSEQUENT EVENTS

     On April 23, 1998, the Company consummated an initial public offering
("IPO") of 7,380,000 shares of its Common Stock, with gross proceeds of
$110,700,000 and net proceeds to the Company of $102,951,000.

     The Company also issued, pursuant to two separate private placements, an
aggregate of 897,678 shares of Common Stock to ERE Yarmouth Holdings, Inc., an
indirect wholly-owned subsidiary of Lend Lease Corporation Limited ("Lend
Lease"), and 700,000 shares of Common Stock to FBR Asset Investment Corporation,
an affiliate of Friedman, Billings, Ramsey & Co., Inc., each of which closed
concurrently with the closing of the IPO, at $13.95 per share, with total
proceeds to the Company of $22,287,608.

     The Company entered into a Management Agreement (the "Management
Agreement") with ERE Yarmouth, Inc. (the "Manager"), an indirect wholly-owned
subsidiary of Lend Lease, under which the Manager will advise the Company on
various facets of its business and manage its day-to-day operations, subject to
the supervision of the Company's Board of Directors.

                                 March 31, 1998
                                   (Unaudited)

     Pursuant to the Management Agreement, the Company will pay the Manager a
quarterly base management fee equal to the following:

<TABLE>
     <S>                                             <C>
     For the first four fiscal quarters.....         1.00% per annum of the Average Invested Assets 1 of the
                                                     Company
     During each fiscal quarter
          thereafter........................         0.85% per annum of the Average Invested Assets up to $1 billion

                                                     0.75% per annum of the Average  Invested Assets from $1 billion to
                                                     $1.25 billion

                                                     0.50% per annum of the Average Invested Assets in excess of $1.25
                                                     billion
</TABLE>

     The Management Agreement also provides for a quarterly incentive management
fee equal to the product of (A) 25% of the dollar amount by which (1) (a) Funds
From Operations 2 (before the incentive fee) of the Company for the applicable
quarter per weighted average number of shares of Common Stock outstanding plus
(b) gains (or minus losses) from debt restructuring or sales of assets not
included in Funds From Operations of the Company for such quarter per weighted
average number of shares of Common Stock outstanding, exceed (2) an amount equal
to (a) the weighted average of the price per share at initial offering and the
prices per share at any secondary offerings by the Company multiplied by (b) 25%
of the sum of the Ten-Year U.S. Treasury Rate plus four percent, and (B) the
weighted average number of shares of Common Stock outstanding.

     In addition, the Management Agreement provides for a termination fee equal
to the sum of the base management fee and incentive management fee, if any,
earned during the immediately preceding four fiscal quarters.

     The Company adopted a stock option plan to provide incentive compensation
for the Company's executive officers and the Manager, whereby the Manager was
granted an option to purchase 1,166,667 shares of Common Stock of the Company
exercisable at the initial public offering price. One-fourth of the Manager's
options will be exercisable on each of the first four anniversaries of the
closing date of the IPO.

     The underwriters sold 79,586 shares of Common Stock that were purchased in
the IPO to directors and officers of the Company and the Manager for $15.00 per
share. Pursuant to the Company's Directed Share Program, such individuals were
granted an option to purchase one share of Common Stock for each share of Common
Stock purchased in the IPO. One-fifth of the options were exercisable
immediately, and one-fifth of the options will be exercisable on each of the
first four anniversaries of the closing date of the IPO. The individuals who
bought shares of Common Stock pursuant to such reservation were required to
agree not to offer or sell or contract to sell or otherwise dispose of any
Common Stock of the Company without the prior consent of the underwriters'
representatives for a period of one year from the date of the IPO.


1 The term "Average Invested Assets" for any period means the average of the
aggregate book value of the assets of the Company, including a proportionate
amount of the assets of all of its direct and indirect subsidiaries, before
reserves for depreciation or bad debts or other similar noncash reserves less
(i) uninvested cash balances and (ii) the book value of the Company's CMO
liabilities, computed by dividing (a) the sum of such values for each of the
three months during such quarter (based on the book value of such assets as of
the last day of each month) by (b) three.

2 The term "Funds From Operations" as defined by the National Association of
Real Estate Investment Trusts, Inc. means net income (computed in accordance
with generally accepted accounting principles ("GAAP")) excluding gains (or
losses) from debt restructuring and sales of property, plus depreciation and
amortization on real estate assets, and after deduction of preferred stock
dividends, if any, and similar adjustments for unconsolidated partnerships and
joint ventures. Funds From Operations does not represent cash generated from
operating activities in accordance with GAAP and 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 or ability to make distributions.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

     The Company was incorporated in Georgia on December 16, 1997 for the
purpose of investing in multifamily and commercial Mortgage Loans, CMBS
interests, Mezzanine Investments and Real Property. The Company expects to
generate income for distribution to its shareholders primarily from the net
income derived from its investments in real estate related assets. The Company
intends to operate in a manner that permits it to elect, and it intends to
elect, to be subject to tax as a real estate investment trust for federal income
tax purposes. On April 23, 1998, the Company commenced its operations upon
consummation of a public offering of 7,380,000 shares of its Common Stock. The
Company had not conducted any operations as of March 31, 1998.
