Liquidation Plan	Note 2 – Liquidation Plan The Liquidation Plan, as amended by the Board of Directors in accordance with the terms of the Liquidation Plan, provides for an orderly sale of the Company’s assets, payment of the Company’s liabilities and other obligations and the winding down of operations and final dissolution of the Company. The Company is not permitted to make any new investments except to exercise its option (the “WWP Option”) to purchase additional equity interests in Worldwide Plaza, and enter into the transaction relating to Worldwide Plaza pursuant to the Membership Interest Purchase Agreement with a purchaser, a joint venture between an affiliate of SL Green Realty Corp. and a private equity fund sponsored by RXR Realty LLC or to make protective acquisitions or advances with respect to its existing assets (see Note 7). The Company is permitted to satisfy any existing contractual obligations and fund required tenant improvements and capital expenditures at its real estate properties, including real estate properties owned by joint ventures in which the Company owns an interest. The Liquidation Plan enables the Company to sell any and all of its assets without further approval of the stockholders and provides that liquidating distributions be made to the stockholders as determined by the Board. Pursuant to applicable REIT rules, the Company must complete the disposition of its assets by January 3, 2019, two years after the date the Liquidation Plan was approved by the stockholders, in order to deduct liquidating distributions as dividends. To the extent that all of the Company’s assets are not sold by such date, the Company intends to satisfy the requirement by converting the Company to a limited liability company, which will require stockholder approval, or by transferring the remaining assets and liabilities to a liquidating trust. The dissolution process and the amount and timing of distributions to stockholders involves risks and uncertainties. Accordingly, it is not possible to predict the timing or aggregate amount which will be ultimately distributed to stockholders and no assurance can be given that the distributions will equal or exceed the estimate of net assets presented in the Consolidated Statements of Net Assets. The Company expects to continue to qualify as a REIT throughout the liquidation until such time as the Company is converted into a limited liability company, which will require stockholder approval, or any remaining assets are transferred into a liquidating trust. The Board shall use commercially reasonable efforts to continue to cause the Company to maintain its REIT status, provided however, the Board may elect to terminate the Company’s status as a REIT if it determines that such termination would be in the best interest of the stockholders. Although the Board does not intend to do so, the Board may terminate the Liquidation Plan without stockholder approval only (i) if the Board approves the Company to enter into an agreement involving the sale or other disposition of all or substantially all of the assets or common stock by merger, consolidation, share exchange, business combination, sale or other transaction involving the Company or (ii) if the Board determines, in exercise of its duties under Maryland law, after consultation with the Winthrop Advisor, if applicable, or other third party experts familiar with the market for Manhattan office properties, that an adverse change in the market for Manhattan office properties has occurred and reasonably would expect it to adversely affect continuing with the Liquidation Plan. Notwithstanding approval of the Liquidation Plan by the stockholders, the Board may amend the Liquidation Plan without further action by the stockholders to the extent permitted under the current law.

Note 2 – Liquidation Plan

The Liquidation Plan, as amended by the Board of Directors in accordance with the terms of the Liquidation Plan, provides for an orderly sale of the Company’s assets, payment of the Company’s liabilities and other obligations and the winding down of operations and final dissolution of the Company. The Company is not permitted to make any new investments except to exercise its option (the “WWP Option”) to purchase additional equity interests in Worldwide Plaza, and enter into the transaction relating to Worldwide Plaza pursuant to the Membership Interest Purchase Agreement with a purchaser, a joint venture between an affiliate of SL Green Realty Corp. and a private equity fund sponsored by RXR Realty LLC or to make protective acquisitions or advances with respect to its existing assets (see Note 7). The Company is permitted to satisfy any existing contractual obligations and fund required tenant improvements and capital expenditures at its real estate properties, including real estate properties owned by joint ventures in which the Company owns an interest.

The Liquidation Plan enables the Company to sell any and all of its assets without further approval of the stockholders and provides that liquidating distributions be made to the stockholders as determined by the Board. Pursuant to applicable REIT rules, the Company must complete the disposition of its assets by January 3, 2019, two years after the date the Liquidation Plan was approved by the stockholders, in order to deduct liquidating distributions as dividends. To the extent that all of the Company’s assets are not sold by such date, the Company intends to satisfy the requirement by converting the Company to a limited liability company, which will require stockholder approval, or by transferring the remaining assets and liabilities to a liquidating trust.

The dissolution process and the amount and timing of distributions to stockholders involves risks and uncertainties. Accordingly, it is not possible to predict the timing or aggregate amount which will be ultimately distributed to stockholders and no assurance can be given that the distributions will equal or exceed the estimate of net assets presented in the Consolidated Statements of Net Assets.

The Company expects to continue to qualify as a REIT throughout the liquidation until such time as the Company is converted into a limited liability company, which will require stockholder approval, or any remaining assets are transferred into a liquidating trust. The Board shall use commercially reasonable efforts to continue to cause the Company to maintain its REIT status, provided however, the Board may elect to terminate the Company’s status as a REIT if it determines that such termination would be in the best interest of the stockholders.

Although the Board does not intend to do so, the Board may terminate the Liquidation Plan without stockholder approval only (i) if the Board approves the Company to enter into an agreement involving the sale or other disposition of all or substantially all of the assets or common stock by merger, consolidation, share exchange, business combination, sale or other transaction involving the Company or (ii) if the Board determines, in exercise of its duties under Maryland law, after consultation with the Winthrop Advisor, if applicable, or other third party experts familiar with the market for Manhattan office properties, that an adverse change in the market for Manhattan office properties has occurred and reasonably would expect it to adversely affect continuing with the Liquidation Plan. Notwithstanding approval of the Liquidation Plan by the stockholders, the Board may amend the Liquidation Plan without further action by the stockholders to the extent permitted under the current law.
