NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

      American Real Estate Partners, L.P. (“AREP” or the “Company”) is a master limited partnership formed in Delaware on February 17, 1987. Our general partner is American Property Investors, Inc. (“API”, or, the “General Partner”) The accompanying consolidated financial statements and related footnotes should be read in conjunction with the consolidated financial statements and related footnotes contained in the Company’s annual report on Form 10-K for the year ended December 31, 2004.

      The financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission related to interim financial statements. All adjustments which, in the opinion of management, are necessary to fairly present the results for the interim periods have been made. Certain prior year amounts have been reclassified in order to conform to the current year presentation.

      The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries in which control can be exercised. The Company is considered to have control if it has a direct or indirect ability to make decisions about an entity’s activities through voting or similar rights. All material intercompany accounts and transactions have been eliminated in consolidation.

      The financial information contained herein is unaudited; however, in the opinion of management, all adjustments necessary for a fair presentation of such financial information have been included. All such adjustments are of a normal recurring nature. The results of operations for the three months ended March 31, 2005 are not necessarily indicative of the results to be expected for the full year. Hotel, casino and resort operations are highly seasonal in nature and are not necessarily indicative of results expected for the full year.

      The Company’s March 31, 2004 consolidated financial statements have been restated to reflect the acquisition of Arizona Charlie’s Decatur and Arizona Charlie’s Boulder on May 26, 2004. The acquisition has been accounted for in a manner similar to a pooling-of-interests method since the acquisition was between entities under common control.

      Each of National Energy Group, Inc. (“NEG”), GB Holdings, Inc. (“GBH”), and Atlantic Coast Entertainment Holdings, Inc. (“Atlantic Holdings”), are reporting companies under the Securities Exchange Act of 1934. In addition, American Casino & Entertainment Properties LLC (“American Casino”), voluntarily files annual, quarterly and current reports. Each of these reports is separately filed with the Securities and Exchange Commission. Annual, quarterly and current reports are available to the public free of charge at the SEC website at http://www.sec.gov.

      a. The Company currently owns 50.01% of the outstanding common stock of NEG, and all of NEG’s approximately $148.6 million aggregate principal amount of notes.

The Company has entered into an agreement to acquire the other membership interest in Holding LLC for an aggregate of up to 11,344,828 of depositary units, valued at $29.00 per unit, or an aggregate of up to $329 million, from affiliates of Mr. Icahn. The number of depositary units is subject to reduction based upon Holding LLC’s oil and gas reserve reports, prepared by an independent reserve engineering firm.

      b. On December 6, 2004, the Company purchased $27.5 million aggregate principal amount of term notes issued by TransTexas Gas Corporation (“TransTexas”), which constitutes 100% of the outstanding term notes of TransTexas (the “TransTexas Notes”).

      c. The Company currently owns approximately 36.3% of the outstanding common stock of GBH. On December 27, 2004, the Company purchased $37.0 million principal amount of the 3% notes due September 2008 issued by GBH’s subsidiary, Atlantic Holdings, bringing the Company’s ownership of that debt to approximately $63.9 million principal amount, or approximately 96.4% of the principal amount outstanding. The notes may be paid in full, at the option of the holders of a majority of their principal amount, with common stock of Atlantic Holdings. The Company also owns warrants to purchase, upon the occurrence of certain events, approximately 10.0% of the fully diluted common stock of Atlantic Holdings. Atlantic Holdings owns 100% of ACE Gaming LLC (“ACE Gaming”), the owner and operator of The Sands Hotel and Casino located in Atlantic City, New Jersey (the “Sands”). The Company has entered into an agreement with affiliates of Mr. Icahn to acquire an additional approximate 41.2% of the outstanding common stock of GBH and warrants to purchase, upon the occurrence of certain events, an additional approximate 11.3% of the fully diluted common stock of Atlantic Holdings for an aggregate of 413,793 depositary units, valued at $29.00 per unit, or an aggregate of $12.0 million plus up to an additional 206,897 depositary units, valued at $29.00 per unit, or an additional $6.0 million, if Atlantic Holdings meets certain earnings targets during 2005 and 2006. Upon completion of the acquisition, the Company will own approximately 77.5% of the outstanding GBH common stock and warrants to purchase, upon the occurrence of certain events, approximately 21.3% of the fully diluted common stock of Atlantic Holdings. Warrants to purchase, upon the occurrence of certain events, approximately 27.5% of the fully diluted common stock of Atlantic Holdings are currently outstanding. Under certain circumstances, the Atlantic Holdings notes are convertible into approximately 43.7% of the fully diluted common stock of Atlantic Holdings. If all outstanding notes were converted and warrants exercised, giving effect to the acquisition, the Company would own approximately 63.4% of the Atlantic Holdings common stock, GBH would own approximately 28.8% of the Atlantic Holdings common stock and the remaining shares would be owned by the public.

      e. In 1997 the Company entered into a license agreement with an affiliate of API for office space. Pursuant to the license agreement, the Company has the non-exclusive use of approximately 2,275 square feet for which it pays monthly rent of $11,185 plus 10.77% of certain “additional rent.” The terms of such license agreement were reviewed and approved by the Audit Committee of the Board of Directors of the General Partner (the “Audit Committee”). The agreement, which expired in May 2004, has been extended on a month-to-month basis. For each of the three months ended March 31, 2005 and 2004, the Company paid rent of approximately $39,000.

      f. American Casino billed GBH, the holding company for the Sands, approximately $136,000 and $50,000 for administrative services performed by American Casino personnel during the three months ended March 31, 2005 and 2004, respectively.

      i. An affiliate of the General Partner provided certain administrative services to the Company which paid to such affiliate approximately $22,000 and $20,000 in the three months ended March 31, 2005 and 2004, respectively.

      j. As of May 1, 2005, affiliates of Mr. Icahn owned 9,346,044 Preferred Units and 39,896,836 Depositary Units which represent 86.5% of the outstanding Preferred Units and Depositary Units.

      We continue to pursue the approval and development of our New Seabury resort community located on Cape Cod overlooking Nantucket Sound and Martha’s Vineyard. Although there are approximately 178 acres of developable land, construction has been delayed by a dispute with the Cape Cod Commission, a regional planning body which asserted jurisdiction over the development in January 2002, In February 2002, New Seabury Properties L.L.C. (“New Seabury”), the Company’s subsidiary and owner of the property commenced legal action to overturn the Commission’s assertion of jurisdiction. It is the Company’s position that the proposed residential, commercial and recreational development is exempt from the Commission’s jurisdiction.

      The parties are now in settlement discussions. A proposed settlement agreement was endorsed by the Commission staff and presented at a public hearing of the Executive Committee on April 21, 2005. The staff and the Executive Committee have recommended that the full Commission authorize entry into the settlement as presented. If entered into by the Commission and accepted by the Court, New Seabury’s plans to develop up to 400-450 residential private homes and condominium units as well as 10-50,000 square feet of commercial space could proceed immediately. The public hearing was continued until May 12, 2005 at which time the full Commission is expected to vote on the settlement. The Company cannot predict the effect on the development process if the Commission rejects the settlement agreement, the parties proceed with litigation and the Commission is ultimately successful in asserting jurisdiction over any of the development proposals.

      The carrying value of New Seabury’s development assets at March 31, 2005 is approximately $11.0 million.

      On February 7, 2005, AREP and its subsidiary, American Real Estate Finance Corp. (“AREF”), closed on their offering of senior notes due 2013. The notes, in the aggregate principal amount of $480 million, were priced at 100% of principal amount. The notes have a fixed annual interest rate of 7¹/8%, which will be paid every six months on February 15 and August 15, commencing August 15, 2005. The notes will mature on February 15, 2013. AREF, a wholly owned subsidiary of AREP, was formed solely for the purpose of serving as co-issuer of the notes. AREF does not have any operations or assets and does not have any revenues. AREH is a guarantor of the debt; however, no other subsidiaries guarantee payment on the notes. Simultaneously, AREP loaned AREH $474 million which was net of a discount of $6 million. The loan is under the same terms and conditions as AREP’s Senior Notes due in 2013. The Company intends to use the proceeds of the offering, together with depository units to be issued by AREP, to fund the acquisitions described in Note 2, to pay related fees and expenses and for general business purposes. The notes restrict the ability of AREP and AREH, subject to certain exceptions, to, among other things; incur additional debt; pay dividends or make distributions; repurchase stock; create liens; and enter into transactions with affiliates. The notes were issued in an offering not registered under the Securities Act of 1933. At the time AREP issued the notes, AREP entered into a registration rights agreement in which it agreed to exchange the notes for new notes which have been registered under the Securities Act of 1933. If the registration statement is not filed with the SEC by August 8, 2005 or if the registration statement is not declared effective by the SEC on or prior to December 5, 2005 or if AREP fails to consummate an exchange offer in which we issue notes registered under the Securities Act of 1933 in exchange for the privately issued notes within 30 business days after December 5, 2005, then AREP will pay, as liquidated damages, $.05 per week per $1,000 principal amount for the first 90 day period following such failure, increasing by an additional $.05 per week of $1,000 principal amount for each subsequent 90 day period, until all failures are cured.

      Pursuant to the terms of the Preferred Units, on March 4, 2005, the Company declared its scheduled annual preferred unit distribution payable in additional Preferred Units at the rate of 5% of the liquidation preference of $10. The distribution was payable March 31, 2005 to holders of record as of March 15, 2005. A total of 514,133 additional Preferred Units were issued. At March 31, 2005, 10,800,397 Preferred Units are issued and outstanding. In February 2005, the number of authorized Preferred Units was increased to 10,900,000.

      Basic earnings per LP unit are based on earnings which are attributable to limited partners. Net earnings available for limited partners are divided by the weighted average number of shares of limited partnership units outstanding.

      Diluted earnings per LP unit are based on earnings before the preferred pay-in-kind distribution as the numerator with the denominator based on the weighted average number of units and equivalent units outstanding. The Preferred Units are considered to be equivalent units.

      Basic net income per LP unit is derived by dividing net income attributable to the limited partners by the basic weighted average number of LP units outstanding for each period. Diluted earnings per LP unit is derived by adjusting net income attributable to the limited partners for the assumed dilutive effect of the

      To capitalize on favorable real estate market conditions and the mature nature of the Company’s commercial real estate portfolio, AREP has offered its rental real estate portfolio for sale. In the three months ended March 31, 2005, the Company sold four rental real estate properties and a golf resort for approximately $51.9 million which were encumbered by mortgage debt of approximately $10.7 million repaid from the sale proceeds.

      Of the five properties, the Company sold one financing lease property for approximately $8.4 million encumbered by mortgage debt of approximately $3.8 million. The carrying value of this property was approximately $8.2 million; therefore, the Company recognized a gain on sale of approximately $0.2 million in the three months ended March 31, 2005, which is included in income from continuing operations. The Company sold four operating properties for approximately $43.5 million encumbered by mortgage debt of approximately $6.9 million. The carrying value of these properties was approximately $24.8 million. The Company recognized a gain on sale of approximately $18.7 million in the three months ended March 31, 2005, which is included in income from discontinued operations.

      At March 31, 2005, the Company had 11 properties under contract or as to which letters of intent had been executed by potential purchasers, all of which contracts or letters of intent are subject to purchaser’s due diligence and other closing conditions. Selling prices for the properties covered by the contracts or letters of

intent would total approximately $45.5 million. These properties are encumbered by mortgage debt of approximately $25.3 million. At March 31, 2005, the carrying value of these properties is approximately $29.1 million. In accordance with generally accepted accounting principles, only the real estate operating properties under contract or letter of intent, but not the financing lease properties, were reclassified to “Properties Held for Sale” and the related income and expense reclassified to “Income from Discontinued Operations.”

      a. On April 26, 2005, the Board of Directors of our General Partner appointed Jon F. Weber, 46 as President of API. Mr. Weber, who replaces Keith A. Meister as President of API, will assume day-to-day responsibility for our New York-based corporate operations. Mr. Meister will continue to serve as API’s Chief Executive Officer.

      b. On April 6, 2005, the Company closed its previously announced acquisition of TransTexas Gas Corporation for $180.0 million in cash.

      In accordance with generally accepted accounting principles, assets transferred between entities under common control are accounted for at historical costs similar to a pooling of interests, and the financial statements of previously separate companies for periods prior to the acquisition are restated on a combined basis. Had the pooling been consummated at the date of the financial statements, our revenue for the three months ended March 31, 2005 and 2004 would have been increased by $6.1 million and $15.3 million, respectively. Our net income for the three months ended March 31, 2005 and 2004 would have been decreased by $5.3 million and $1.4 million, respectively.

      Summary financial data for TransTexas for the three months ended March 31, 2005 and 2004 are as follows:

      c. In April 2005, the Company sold one property for approximately $2.1 million and will recognize a gain of $1.2 million with respect to this sale.

      d. The Company sold short certain equity securities. Such liability is recorded at market value at the balance sheet date and gains and losses are reflected in the statement of earnings. In the three months ended March 31, 2005, the Company recorded unrealized gains on securities sold short of approximately $21.7 million.

      Based on market value at May 1, 2005, such liability had increased and assuming no change in value at June 30, 2005, the Company would record losses on securities sold short of approximately $27.7 million and $6.0 million in the three and six months ended June 30, 2005, respectively.

      Statements included in Management’s Discussion and Analysis of Financial Condition and Results of Operations which are not historical in nature are intended to be, and are hereby identified as, “forward looking statements” for purposes of the safe harbor provided by Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended by Public Law 104-67.

      Forward-looking statements regarding management’s present plans or expectations involve risks and uncertainties and changing economic or competitive conditions, as well as the negotiation of agreements with third parties, which could cause actual results to differ from present plans or expectations, and such differences could be material.

Certain Trends and Uncertainties

      In addition to certain trends and uncertainties described elsewhere in this report, we are subject to the trends and uncertainties set forth below. Also, please see Certain Trends and Uncertainties on our Annual Report on Form  10-K for the year ended December 31, 2004.

      We are a diversified holding company engaged in a variety of businesses. Our primary business strategy is to continue to grow our core businesses, including real estate, gaming and entertainment, and oil and gas. In addition, we seek to acquire undervalued assets and companies that are distressed or in out of favor industries.

      Our businesses currently include rental real estate; real estate development; hotel and resort operations; hotel and casino operations; oil and gas exploration and production; and investments in equity and debt securities. We may also seek opportunities in other sectors including energy, industrial manufacturing, insurance and asset management.

      In continuation of our strategy to grow our core businesses, we have recently acquired, and have entered into agreements to acquire, additional gaming and entertainment and oil and gas assets from affiliates of Mr. Icahn. See Note 2 “Related Party Transactions.”

      To capitalize on favorable real estate market conditions and the mature nature of our commercial real estate portfolio, we have offered our rental real estate portfolio for sale.

      We have made investments in the gaming industry through our ownership of Stratosphere Casino Hotel & Tower in Las Vegas. Nevada and through our purchase of securities of the entity which owns The Sands Hotel and Casino in Atlantic City, New Jersey. One of our subsidiaries, formed for this purpose, acquired two Las Vegas hotels and casinos, Arizona Charlie’s Decatur and Arizona Charlie’s Boulder, from Mr. Icahn and an entity affiliated with Mr. Icahn, for aggregate consideration of $125.9 million in May 2004. We have entered into an agreement with affiliates of Mr. Icahn pursuant to which we will acquire approximately 41.2% of the outstanding common stock of GB Holdings and warrants to purchase, upon the occurrence of certain events, approximately 11.3% of the fully diluted common stock of Atlantic Holdings, the indirect owner of The Sands Hotel and Casino.

      We have entered into agreements with affiliates of Mr. Icahn to purchase the other membership interest in NEG Holding and 100% of the equity of TransTexas and Panaco, each an oil and gas exploration and production company. The acquisition of Trans Texas closed on April 6, 2005.

      In accordance with GAAP, assets transferred between entities under common control are accounted for at historical costs similar to a pooling of interests and the financial statements of previously separate companies for periods prior to the acquisition are (and, in the case of the pending acquisitions, following the closing of the acquisitions, will be) restated on a combined basis.

Results of Operations

      Gross revenues increase by $28.4 million, or 27.8%, during the three months ended March 31, 2005 as compared to the same period in 2004. This increase reflects increases of $8.6 million in interest income on U.S. government and agency obligations and other investments, $7.8 million in hotel and casino operating income, $4.2 million in hotel and resort operating income, $3.4 million in dividend and other income, $3.3 million in land, house and condominium sales, $2.0 million in accretion of investment in NEG Holding LLC and $0.7 million in NEG management fees partially offset by decreases of $1.0 million in interest income on financing leases and $0.6 million in equity in earnings of GB Holdings. The increase in interest income on U.S. government and agency obligations and other investments is primarily due to increased interest income from the senior debt proceeds, increased interest income from other investments and increased interest income on debt securities of affiliates. The increase in hotel and casino operating income is primarily due to an increase in casino, hotel and food and beverage revenues. Hotel and resort operating income increased primarily due to the Grand Harbor acquisition. The increase in land, house and condominium sales is primarily due to an increase in the number of units sold.

      Expenses increased by $26.9 million, or 34.4%, during the three months ended March 31, 2005 as compared to the same period in 2004. This increase reflects increases of $13.0 million in interest expense, $4.0 million in hotel and resorts operating expenses, $3.7 million in the cost of land, house and condominium sales, $3.4 million in hotel and casino operating expenses, and $3.2 million in general and administrative expenses partially offset by decreases of $0.3 million in depreciation and amortization and $0.1 million in property expenses. The increase in interest expense is primarily attributable to interest on the Senior Notes issued by the Company in May 2004 and February 2005, respectively. The increase in hotel and resort operating expenses is primarily due to the Grand Harbor acquisition. The increase in costs of land, house and condominium sales is due to increased sales as noted above. The increase in hotel and casino operating expenses is primarily attributable to increased costs associated with increased revenues. The increase in general and administrative expenses is primarily attributable to expenses incurred by NEG in connection with the increase in NEG management fees, legal fees, the addition of Grand Harbor and state and local franchise taxes in connection with the 2004 property sales.

      Operating income increased during the three months ended March 31, 2005 by $1.5 million as compared to the same period in 2004 as detailed above.

      Earnings from land, house and condominium operations decreased by $0.4 million in the three months ended March 31, 2005 compared to the same period in 2004 due to a decrease in margins on units sold.

      Earnings from hotel and casino operating properties increased by $4.4 million during the three months ended March 31, 2005 due to increased revenues throughout the properties.

      A gain on property transactions from continuing operations of $0.2 million was recorded in the three months ended March 31, 2005 as compared to $6.0 million in the same period in 2004.

      Other losses of $0.2 million were recorded in the three months ended March 31, 2005. There were no significant losses in 2004.

      A gain on sale of marketable equity securities of $28.9 million was recorded in the three months ended March 31, 2004. There were no such gains in the comparable period of 2005.

      Unrealized gains on securities sold short of $21.7 million were recorded in the three months ended March 31, 2005. There were no such gains in 2004.

      Income from continuing operations before income taxes decreased by $11.7 million in the three months ended March 31, 2005 as compared to the same period in 2004 as detailed above.

      Income tax expense of $7.6 million was recorded in the three months ended March 31, 2005 as compared to $6.2 million in the same period in 2004. Income tax expense was recorded by our corporate subsidiaries, NEG and American Casino.

      Income from continuing operations decreased by $13.1 million in the three months ended March 31, 2005 as compared to the same period in 2004 as detailed above.

      Income from discontinued operations increased by $9.5 million in the three months ended March 31, 2005, as compared to the same period in 2004 due to gains on property dispositions.

      Net earnings for the three months ended March 31, 2005 decreased by $3.6 million as compared to the three months ended March 31, 2004, primarily due to decreased gain on sales of real estate from continuing operations ($5.9 million) and decreased gain on sale of marketable equity securities ($28.9 million) partially offset by unrealized gains on securities sold short ($21.7 million) and increased income from discontinued operations ($9.5 million).

Capital Resources and Liquidity

      Net cash provided by operating activities was $27.3 million for the three months ended March 31, 2005 as compared to $29.1 million in the comparable period of 2004. This decrease was primarily due to an increase in restricted cash ($8.7 million), an increase in due from brokers ($2.5 million), a decrease in accounts payable

and accrued expenses ($13.2 million) a decrease in discontinued operations ($2.4 million) and a decrease in cash flow from other operations ($1.5 million) partially offset by a decrease in receivables and other assets ($15.2 million), a decrease in land and construction-in-progress ($6.4 million), and an increase in deferred income tax expense ($4.9 million).

      The following table reflects, at March 31, 2005, our contractual cash obligations, subject to certain conditions, due over the indicated periods and when they come due (in $ millions):

      The American Casino 7.85% senior secured notes due 2012 contain restrictions on dividends and distributions to us, the purchase of our equity interests in American Casino, loans to us, as well as other transactions with us. American Casino also has a $20 million credit facility which contains similar restrictions. At March 31, 2005, there were no borrowings under the credit facility. The restrictions imposed by American Casino’s Senior Secured Notes and the credit facility likely will preclude our receiving payments from the operations of our principal hotel and gaming properties. American Casino accounted for 63.4% of our revenues in the three months ended March 31, 2005 and 77% of our operating income in that period.

      On May 12, 2004, we closed on our offering of senior notes due 2012. The notes, in the aggregate principal amount of $353 million, were priced at 99.266%. The notes have a fixed annual interest rate of 8¹/8%.

      On February 7, 2005, we closed on our offering of Senior Notes due 2013. The notes, in the aggregate principal amount of $480 million, bear interest at the rate of 7¹/8% per annum.

      We intend to use the proceeds from these notes for general business purposes, including to pursue our primary business strategy of acquiring undervalued assets in our existing lines of business or other businesses and to provide additional capital to grow our existing businesses.

      Our Senior Notes restrict the payment of cash dividends or distributions, the purchase of equity interests or the purchase, redemption, defeasance or acquisition of debt subordinated to the Senior Notes as “restricted payments.” The notes also prohibit the incurrence of debt, or the issuance of disqualified stock, as defined, with certain exceptions provided that we may incur debt or issue disqualified stock if, immediately after such incurrence or issuance, the ratio of the aggregate principal amount of all outstanding indebtedness (on a consolidated basis determined in accordance with generally accepted accounting principles) to tangible net worth of the Company (on a consolidated basis determined in accordance with generally accepted accounting principles), and taking into account any changes as a result of any (x) restricted payments, (y) assets sales or (z) contributions to equity or from the issuance on sale of equity interests or from the exchange or conversion of disqualified stock or debt would have been less than 1.75 to 1. As of March 31, 2005, such ratio was .83 to 1. In addition, the notes require that on each quarterly determination date (defined for each of the Company’s first, second and third quarter as the earlier of (1) the date we would have been required to file a quarterly report with the SEC on Form 10-Q and (2) the date we file our quarterly report) that the Fixed Charge Coverage Ratio of us and the guarantors of the notes (currently only AREH) for the four consecutive fiscal quarters most recently completed prior to such quarterly determination date be at least 1.5 to one. For the four quarters ended March 31, 2005, such ratio was 2.37 to 1. If the ratio is less than 1.5 to 1, we will be deemed to have satisfied this test if there is deposited cash, which together with cash previously deposited for such purpose and not released, equal to the amount of interest on the notes for one year. If at any subsequent

quarterly determination date, the ratio is at least 1.5 to 1, the funds will be released to us. The notes also require, on each quarterly determination date, that the ratio of total unencumbered assets, as defined, to the principal amount of unsecured indebtedness, as defined, be greater than 1.5 to 1.0 as of the last day of the most recently completed fiscal quarter. As of March 31, 2005, such ratio was 2.71 to 1. The notes also restrict the creation of liens, mergers, consolidations and sales of substantially all of our assets, and transactions with affiliates.

      At March 31, 2005, we had 11 properties under contract or as to which letters of intent had been executed by the potential purchaser, all of which contracts or letters of intent are subject to purchaser’s due diligence and other closing conditions. Selling prices for the properties covered by the contracts or letters of intent would total approximately $45.5 million. These properties are encumbered by mortgage debt of approximately $25.3 million.

      Net proceeds from the sale or disposal of portfolio properties totaled approximately $41.2 million in the three months ended March 31, 2005. During the comparable period of 2004, sales proceeds totaled approximately $18.7 million.

      Capital expenditures for real estate, and hotel, casino and resort operations were approximately $4.8 million and $1.7 million during the three months ended March 31, 2005 and 2004, respectively. In 2005, capital expenditures are currently expected to be approximately $20 million.

      During the three months ended March 31, 2005 and 2004, approximately $1.0 million and $1.7 million, respectively, of mortgage principal payments were repaid. These amounts do not include mortgage debt repaid in connection with sales of real estate.

      Our cash and cash equivalents and investment in U.S. government and agency obligations increased by $455.1 million during the three months ended March 31, 2005 primarily due to proceeds from the issuance of our 7¹/8% senior notes due 2013 ($474.0 million), property sales proceeds ($41.2 million), cash provided by operations ($27.3 million) and repayment of affiliates’ debt securities ($2.7 million), partially offset by purchase of equity securities ($66.3 million), repayment of affiliate debt ($16.6 million), capital expenditures ($4.8 million) and other ($6.4 million).

      We are continuing to pursue assets, including assets that may not generate positive cash flow, are difficult to finance or may require additional capital, such as properties for development, non-performing loans, securities of companies that are undergoing or that may undergo restructuring, and companies that are in need of capital. We are also continuing to identify shorter-term investments. All of these activities require us to maintain a strong capital base and liquidity. It has been our policy to hold our cash rather than to make distributions to partners. The Board of Directors has commenced a review of our distribution policy and it is uncertain when the Board will conclude its review or whether the Board will authorize distributions.

Off Balance Sheet Arrangements

      We do not maintain any off-balance sheet transactions, arrangements, obligations or other relationships with unconsolidated entities or others.

      The United States Securities and Exchange Commission requires that registrants include information about primary market risk exposures relating to financial instruments. Through our operating and investment activities, we are exposed to market, credit and related risks, including those described elsewhere herein. As we may invest in debt or equity securities of companies undergoing restructuring or undervalued by the market, these securities are subject to inherent risks due to price fluctuations, and risks relating to the issuer and its industry, and the market for these securities may be less liquid and more volatile than that of higher rated or more widely followed securities.

      Other related risks include liquidity risks, which arise in the course of our general funding activities and the management of our balance sheet. This includes both risks relating to the raising of funding with

appropriate maturity and interest rate characteristics and the risk of being unable to liquidate an asset in a timely manner at an acceptable price. Real estate investments by their nature are often difficult or time-consuming to liquidate. Also, buyers of minority interests may be difficult to secure, while transfers of large block positions may be subject to legal, contractual or market restrictions. Our other operating risks include lease terminations, whether scheduled terminations or due to tenant defaults or bankruptcies, development risks, and environmental and capital expenditure matters, as described elsewhere herein.

      We invest in U.S. government and agency obligations which are subject to interest rate risk. As interest rates fluctuate, we will experience changes in the fair value of these investments with maturities greater than one year. If interest rates increased 100 basis points, the fair value of these investments at March 31, 2005, would decline by approximately $200,000.

      We employ internal strategies intended to mitigate exposure to these and other risks. We, on a case by case basis with respect to new investments, perform internal analyses of risk identification, assessment and control. We review credit exposures, and seeks to mitigate counterparty credit exposure through various techniques, including obtaining and maintaining collateral, and assessing the creditworthiness of counterparties and issuers. Where appropriate, an analysis is made of political, economic and financial conditions, including those of foreign countries. Operating risk is managed through the use of experienced personnel. We seek to achieve adequate returns commensurate with the risk it assumes. We utilize qualitative as well as quantitative information in managing risk.

      a. As of March 31, 2005, our management, including our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s and our subsidiaries’ disclosure controls and procedures pursuant to the Exchange Act Rule 13a-15(e) and 15d-15(e). Based upon such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are currently effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by us in such reports is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

      b. We are continuing our efforts to evaluate the effectiveness of the design and operation of our disclosure controls and procedures and our internal controls over financial reporting. Throughout 2004, we implemented a program and engaged independent consultants to assist us in the evaluation and improvement of the effectiveness of the design and operation of our disclosure controls and procedures and our internal controls over financial reporting. No material weaknesses were identified by management or our independent consultants. As noted in our Quarterly Report on Form 10-Q for the nine months ended September 30, 2004 our independent consultants and management identified a significant deficiency in the consolidation process involving lack of segregation of duties within the accounting department. We retained an assistant controller and our computer system has been updated in order to address this concern and to enhance financial reporting controls. During the three months ended March 31, 2005, we continued to make improvements to our computer system to enhance internal controls. In addition to retaining the services of an independent consultant to evaluate the effectiveness our internal controls, we determined to retain an additional assistant controller to review internal controls for us and our rental real estate, real estate development and hotel and resort operations. The new assistant controller began work in January 2005. During the three months ended March 31, 2005, no change in our internal control over financial reporting occurred that has affected materially, or is reasonably likely to affect materially, such internal controls.
