Independent Auditors’ Report

The Partners
101 Hudson Street:

We have audited the accompanying statement of revenue and certain operating expenses of 101 Hudson Street (the Property) for the year ended December 31, 2004. This statement is the responsibility of the Property’s management. Our responsibility is to express an opinion on this statement based on our audit.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement is free of material misstatement. An audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the statement. We believe that our audit provides a reasonable basis for our opinion.

The accompanying statement of revenue and certain operating expenses was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission and for inclusion in the Forms 8-K of Mack-Cali Realty Corporation and Mack-Cali Realty, L.P., as described in note 1. This presentation is not intended to be a complete presentation of the Property’s revenues and expenses.

In our opinion, the statement of revenue and certain operating expenses referred to above presents fairly, in all material respects, the revenue and certain operating expenses described in note 1 of 101 Hudson Street for the year ended December 31, 2004, in conformity with accounting principles generally accepted in the United States of America.

101 HUDSON STREET

Notes to Statement of Revenue and Certain Operating Expenses

December 31, 2004

(1) Organization and Basis of Presentation

The accompanying statement of revenues and certain operating expenses includes the accounts of the property known as 101 Hudson Street (the Property), a 1.2 million square-foot office property located in Jersey City, New Jersey. The Property was owned by several entities, which were directly or indirectly owned by Hudson Street Owners Limited Partnership I and Hudson Street Owners Limited Partnership II (collectively, the Partners).

The accompanying statement of revenue and certain operating expenses for the year ended December 31, 2004 was prepared for the purpose of complying with the provisions of Article 3.14 of Regulation S-X promulgated by the Securities and Exchange Commission (SEC), which requires certain information with respect to real estate operations to be included with certain filings with the SEC. The statement of revenue and certain operating expenses includes the historical revenue and certain operating expenses of the Property for the year ended December 31, 2004, exclusive of interest income, write-offs of straight-line rental receivables, mortgage interest expense, and depreciation and amortization, which may not be comparable to the corresponding amounts reflected in the future operations of the Property under its new ownership by subsidiaries of Mack-Cali Realty Corporation and Mack-Cali Realty, L.P., who collectively acquired the ownership interests in the Property on March 2, 2005.

(2) Significant Accounting Policies

(a) Revenue Recognition

Revenue relating to operating leases is recognized on a straight-line basis over the lease term, regardless of when payments are due. During 2004, contractual rental payments received in excess of straight-line rental revenues recognized were $5,193,263.

The Property is subject to a concentration of credit risk as three tenants (note 3) aggregate approximately 73% of the amount recorded as revenue for the year ended December 31, 2004.

(b) Escalations and Recoveries from Tenants

Certain operating expenses incurred in the operations of the Property are recoverable from the tenants. The recoverable amounts are based on actual expenses incurred. Expense recoveries are recognized as revenue in the period in which the applicable costs are incurred.

(c) Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

(3) Operating Leases

The Property is leased to tenants under operating leases with expiration dates through 2017. Substantially all of the leases provide for annual base rents plus recoveries and escalation charges based upon the tenants proportionate share of, and/or increases in, real estate taxes and certain operating costs, as defined, and the pass-through of charges for electrical usage. One lease also provides for rents based on a percentage of the tenant’s sales over a stipulated amount.

The Property has entered into a lease agreement dated December 29, 1989, with an affiliate of one of the Partners (Tenant). Under the terms of the lease, Tenant will lease approximately 49% of the building for an initial term through March 31, 2007. The lease contains five renewal options, each for five years. The lease provides that Tenant will reimburse the Property for its proportionate share of the Property’s operating expenses, as defined. The obligations of Tenant under the lease have been guaranteed by Merrill Lynch & Co., Inc.

Base annual rentals under the lease are as follows:

April 1992 – March 1997	$	8,860,439
April 1997 – March 2002	9,450,613
April 2002 – March 2007	10,040,787

The Property also entered into a lease agreement, during 1994, with Lehman Brothers Holding, Inc. (Lehman). Under the original terms of the lease, Lehman leased approximately 399,000 square feet, or 32% of the building, for an initial term through December 31, 2010. The lease contains two renewal options, each of five years at the prevailing market rate. The lease provides that Lehman will reimburse the Property for its proportionate share of the Property’s operating expenses, as defined.

Effective November 1, 2004, Lehman surrendered approximately 192,000 square feet of space. Upon surrendering this space, Lehman now leases approximately 207,000 square feet, or 17% of the building, through December 31, 2010. As such, the accumulated straight-line base rental revenue recognized over the term in excess of contractual payments received, of $3,180,255, was written off in 2004, since those future payments were no longer due to be received. This amount written off has not been included in the accompanying statement of revenues and certain operating expenses since it is not indicative of future operations. This space has been re-leased as described below.

Base annual rentals under the original lease, net of surrendered space are as follows:

January 2001 – October 2004	$	5,890,582
December 2004 – December 2005	3,058,582
Janaury 2006 – December 2010	3,420,667

During 2004, the Property entered into a lease agreement with National Union Fire Insurance Company (NUFIC) to assume the space previously surrendered by Lehman. Under the terms of the lease, NUFIC has leased approximately 208,000 square feet, or 16% of the building, for an initial term through December 31, 2012.

Base annual rentals under the lease are as follows:

November 2004 – December 2008	$	4,472,129
January 2009 – December 2010	5,096,147
Janaury 2011 – December 2012	6,240,180

Expected future minimum rentals to be received from tenants under noncancelable leases, excluding renewal options, in effect at December 31, 2004 are as follows:

	Amount
2005	$	22,644,982
2006	23,016,609
2007	15,269,870
2008	11,795,101
2009	11,585,201
Thereafter	24,876,568
	$	109,188,331

The total expected future minimum rentals presented above do not include amounts that may be received under leases for percentage rents or other charges related to escalations and recoveries from tenants for expenses.

(4) Transactions with Affiliates

LCOR, Inc., an affiliate, performed various services on behalf of the Partnership including accounting, maintenance, and data processing services in 2004. The cost for these services ($645,691 in 2004) is included in the respective expense caption in the accompanying statement of revenue and certain operating expenses.

For its services in connection with the management of the Property’s affairs, LCOR, Inc. received a management fee equal to 3% of gross receipts, as defined. Management fees totaling $1,048,108 were incurred by the Property during 2004.

If an unrelated third party had provided such services, then the amounts paid for these services may have been different.

(5) Operating Services

Operating services expenses consisted of the following for the year ended December 31, 2004:

Maintenance, repairs, and supplies	$	2,001,359
Salaries and related costs	1,867,218
Insurance	347,939
Tenant services	2,822,167
Other	749,455
	$	7,788,138

(6) Real Estate Taxes

The Property has an agreement with the City of Jersey City requiring the payment of an annual service charge to the City of Jersey City in lieu of real estate taxes (the Agreement) which ends in December 2006. The Agreement currently provides for the payment of a minimum annual service charge of approximately $4,193,000, subject to certain adjustments as provided in the Agreement. At the conclusion of the Agreement, it is expected that the Property will be assessed by the municipality and be subject to real estate taxes at the then-prevailing rates.
