             Report of Independent Registered Public Accounting Firm

Plan Administrator
Reckson 401(k) Plan
Retirement and Benefits Committee

We have audited the accompanying statements of net assets available for benefits
of Reckson 401(k) Plan (the "Plan") as of December 31, 2003 and 2002, and the
related statement of changes in net assets available for benefits for the year
ended December 31, 2003. These financial statements are the responsibility of
the Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2003 and 2002, and the changes in its net assets available for
benefits for the year ended December 31, 2003, in conformity with U.S. generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) at December 31, 2003 is presented for the purpose of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

1. DESCRIPTION OF THE PLAN

The following description of the Reckson 401(k) Plan (the "Plan") provides only
general information. Participants should refer to the Plan agreement for a more
complete description of the Plan's provisions.

GENERAL

The Plan was created on January 1, 2001 for the purpose of providing eligible
employees of Reckson Management Group, Inc. (the "Employer") and its related
companies (collectively, the "Affiliates") that participate in the Plan
(collectively, the "Participating Employers") with an opportunity to increase
their savings on a tax-favored basis. Shares of the common stock of Reckson
Associates Realty Corp. ("Reckson") are among the investment options offered to
participants pursuant to the Plan.

The Plan is a defined contribution plan sponsored by the Employer covering all
eligible full-time employees of the Participating Employers who have completed
six months of service and are age twenty-one or older. Effective January 1,
2004, an employee is considered an eligible participant upon the completion of
three months of service and is age twenty-one or older.

The following Participating Employers participated in the Plan during the years
ended December 31, 2003 and 2002:

     Reckson Management Group, Inc.
     Reckson Construction Group, Inc.
     RANY Management Group, Inc.

The Plan is subject to the provisions of the Employee Retirement Income Security
Act of 1974 ("ERISA").

                    Notes To Financial Statements (continued)

1. DESCRIPTION OF THE PLAN (CONTINUED)

CONTRIBUTIONS

During calendar years prior to 2004, participants were able to contribute up to
15% of pretax annual compensation, as defined in the Plan. Commencing January
1, 2004, participants may contribute up to 30% of their pretax annual cash
compensation and up to 15% of their pretax cash bonus, as defined in the Plan.
Participants may also roll over amounts representing distributions from other
qualified benefit or defined contribution plans. In addition, the Plan permits
individuals who are at least age 50 before the end of the calendar year to make
a catch-up contribution. Participants direct the investment of their
contributions into various investment options offered by the Plan. As of
December 31, 2003, the Plan offered 13 mutual funds and the common stock of
Reckson as investment options for participants. Additional discretionary
matching contributions may be contributed at the option of the Participating
Employers. Contributions are subject to certain limitations.

The aggregate of all employee contributions are subject to the limitations of
Section 401(k) of the Internal Revenue Code.

Employer contributions are based on a discretionary amount determined by the
Participating Employer's management. During the years ended December 31, 2003
and 2002, the Participating Employers did not contribute to the Plan. Commencing
with the calendar year beginning January 1, 2004, the Participating Employers
have elected to match 50% to eligible participants deferral contribution up to
3% of their annual compensation, as defined, up to an aggregate of $1,000 per
employee per year.

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's contributions and
allocations of Plan earnings, and charged with an allocation of the Plan's
administrative expenses, if not paid by the Participating Employer. Allocations
are based on participant earnings or account balances, as defined. The benefit
to which a participant is entitled is the benefit that can be provided from the
participant's vested account.

VESTING

Participants are immediately 100% vested in their contributions and earnings
thereon. Additionally, a participant is eligible for employer matching
contributions, if any, after one year of credited service, which then vests
ratably based on five years of credited service.

                    Notes To Financial Statements (continued)

1. DESCRIPTION OF THE PLAN (CONTINUED)

PARTICIPANT LOANS

Participants may generally borrow from their accounts up to 50 percent of their
vested account balance. The loans are secured by the balance in the
participant's account and bear interest at the U.S. prime lending rate plus
one-half percentage point.

PLAN TERMINATION

Although it has not expressed any intent to do so, the Participating Employers
have the right under the Plan to terminate the Plan subject to the provisions of
ERISA. In the event of Plan termination, participants will become 100 percent
vested in their accounts.

PAYMENT OF BENEFITS

On termination of service, a participant may elect to receive a lump-sum amount
equal to the value of the participant's vested interest in his or her account.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The financial statements of the Plan are prepared under the accrual basis of
accounting in accordance with U.S. generally accepted accounting principles.

INVESTMENT VALUATION AND INCOME RECOGNITION

The Plan's investments are stated at fair value. Quoted market prices are used
to value investments. Shares of mutual funds are valued at the net asset value
of shares held by the Plan at year-end. The participant loans are valued at
their outstanding balances, which approximate fair value.

Purchases and sales of securities are recorded on a trade-date basis. Dividends
are recorded on the ex-dividend date.

USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that effect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

4. RELATED PARTY TRANSACTIONS

During the years ended December 31, 2003 and 2002, the Plan received $34,063 and

5. INCOME TAX STATUS

The Plan has not received a determination letter from the Internal Revenue
Service stating that the Plan is qualified under Section 401(a) of the Internal
Revenue Code. However, the Plan Administrator believes that the Plan is
qualified and, therefore, the related trust is exempt from taxation.
