Any disputed items resolved in writing between the Buyer and the Sellers within such ten Business Day period shall be final and binding with respect to such items, and if the Sellers and the Buyer agree in writing on the resolution of each disputed item specified by the Buyer in the Buyer Adjustment Statement Objection and the calculation of the Final Adjustment Amount, the Final Adjustment Amount so determined shall be final and binding on the parties for all purposes hereunder. If the Sellers and the Buyer have not resolved all such differences by the end of such ten Business Day period, the Sellers and the Buyer shall submit, within 15 Business Days, in writing, to an independent public accounting firm (the "Independent Accounting Firm"), their briefs detailing their views as to the nature and amount of each item remaining in dispute and the calculation of the Final Adjustment Amount, and the Independent Accounting Firm shall make a written determination as to each such disputed item and the calculation of the Final Adjustment Amount, which determination shall be final and binding on the parties for all purposes hereunder. The Independent Accounting Firm shall be authorized to resolve only those items remaining in dispute between the parties in accordance with the standards set forth in this Section 2.7 within the range of the difference between the Buyer's position with respect thereto and the Sellers' position with respect thereto. The determination of the Independent Accounting Firm shall be based solely on the briefs submitted by the parties and not on independent review, and shall be accompanied by a certificate of the Independent Accounting Firm that it reached such determination in accordance with the provisions of this Section 2.7. The Independent Accounting Firm shall be Ernst & Young LLP or, if such firm is unable or unwilling to act, such other independent public accounting firm of national standing as shall be agreed promptly in writing by the Sellers and the Buyer. The Sellers and the Buyer shall use their commercially reasonable efforts to cause the Independent Accounting Firm to render a written decision resolving the matters submitted to it within 20 Business Days following the submission thereof. Judgment may be entered upon the written determination of the Independent Accounting Firm in any court having competent jurisdiction over the parties or their assets. The costs of any dispute resolution pursuant to this Section 2.7(c), including the fees and expenses of the Independent Accounting Firm and of any enforcement of the determination thereof, shall be borne by the parties in inverse proportion as they may prevail on the matters resolved by the Independent Accounting Firm, which proportionate allocation shall be calculated on an aggregate basis based on the relative dollar values of the amounts in dispute and shall be determined by the Independent Accounting Firm at the time the determination of such firm is rendered on the merits of the matters submitted. The fees and disbursements of the auditors and Representatives of each party incurred in connection with their preparation or review of the Final Adjustment

Statement and preparation or review of any Buyer Adjustment Statement Objection, as applicable, shall be borne by such party.

(d) The Purchase Price shall be increased or decreased, as the case may be, as follows:

(i) if the Final Adjustment Amount as finally determined pursuant to this Section 2.7 is greater than the Pre-Closing Adjustment Amount, the Purchase Price shall be increased in an amount equal to the difference between the Final Adjustment Amount and the Pre-Closing Adjustment Amount, and the Buyer shall pay such amount to the Sellers; and

(ii) if the Final Adjustment Amount as finally determined pursuant to this Section 2.7 is less than the Pre-Closing Adjustment Amount, the Purchase Price shall be decreased in an amount equal to the difference between the Final Adjustment Amount and the Pre-Closing Adjustment Amount, and the Sellers, jointly and severally, shall pay such amount to the Buyer.

(e) Amounts to be paid pursuant to Section 2.7(d) shall bear interest from the Closing Date to the date of such payment at a rate equal to the rate of interest from time to time published in The Wall Street Journal as the prime rate, calculated on the basis of a year of 365 days and the number of days elapsed. Payments in respect of Section 2.7(d) shall be made within three Business Days of final determination of the Final Adjustment Amount pursuant to the provisions of this Section 2.7 by wire transfer of United States dollars in immediately available funds to such account or accounts as may be designated in writing by the party entitled to such payment at least two Business Days prior to such payment date. For the avoidance of doubt, payments in respect of Section 2.7(d) shall not be subject to the Minimum Loss Amount, Basket Amount or other limitations set forth in Section 9.5.

Section 2.8 Transaction Costs. Regardless of law or convention, if the Closing occurs, it shall be the responsibility of the Buyer to, and the Buyer shall, pay or cause to be paid all transaction costs incurred by the Buyer, the Sellers, the Targets and the Subsidiaries in connection with the transactions contemplated hereby, including brokerage fees of CB Richard Ellis, Inc. and Sutton Canyon Capital Corp. and of any other broker engaged by the Buyer or any Affiliate of the Buyer in connection with the transactions described herein, costs of obtaining the Debt Consents, Transfer Taxes (as provided in Section 6.7 below) and title insurance costs (the "Transaction Costs"), and otherwise complete and file all Tax Returns of such Transfer Taxes in connection therewith in a timely manner, provided, however, that the Sellers jointly and severally (rather than the Buyer) shall pay the following: (a) the legal fees and expenses of counsel to any of the Sellers, (b) the legal fees and expenses of counsel to any of the Targets and their Subsidiaries for services rendered at or before the Closing in connection with the transactions contemplated hereby and (c) any brokerage fees incurred by any of the Sellers, Targets, Subsidiaries or any Affiliate of any of them, other than the fees of CB Richard Ellis, Inc. and Sutton Canyon Capital Corp. set forth above.

(a) The Buyer is a sophisticated purchaser and has made its own independent investigation and analysis, basing its valuation of, and decision to purchase, the Shares and to enter into the transactions contemplated by this Agreement and the Ancillary Agreements to which it is a party upon such investigation and analysis. This investigation and analysis was conducted by the Buyer together with its expert advisors and other Representatives that it has engaged for such purpose. The Buyer and its Representatives have been provided with access to the Properties and to other information that they have requested in connection with such investigation and analysis. The Buyer is not relying on any statement, representation or warranty, oral or written, express or implied, made by any of the Sellers, the Targets or the Subsidiaries or any of their Affiliates or Representatives, except as expressly set forth in this Agreement, including the Schedules and the Ancillary Agreements. The Buyer acknowledges that, except as specifically provided in this Agreement or any of the Ancillary Agreements, should the Closing occur, the Buyer shall acquire the Targets without any representation or warranty as to merchantability or fitness for any particular purpose of their respective assets, including the Subsidiaries and the Properties and the Buyer has not relied upon any oral or written information from, including without limitation, any estimates, projections or forecasts prepared by, any of the Sellers, the Targets or any of their Affiliates or Representatives or any employees, agents, consultants, advisors or representatives of the foregoing. The Buyer acknowledges that there are inherent uncertainties in attempting to make such estimates, projections and forecasts and that it takes full responsibility for making its own evaluation of the adequacy and accuracy of any such estimates, projections or forecasts (including the reasonableness of the assumptions underlying any such estimates, projections and forecasts). Without limiting the generality of the foregoing, the Buyer acknowledges and agrees that except as may be expressly set forth in this Agreement or any Ancillary Agreements, the Buyer is acquiring the assets of the Targets, including the Subsidiaries and the Properties, "AS IS" and "WHERE IS" on the Closing Date and, except as expressly set forth in this Agreement, the Sellers are not making any representation or warranty, express or implied, and the Buyer has not

The termination of any Lease or tenancy in accordance with Section 5.1(i) prior to Closing by reason of the tenant's default shall not affect the obligations of the Buyer under this Agreement in any manner or entitle the Buyer to an abatement or credit against the Purchase Price or give rise to any other claim by the Buyer.

Without limiting the generality of the foregoing, except as set forth in Sections 5.1 and 5.16 of this Agreement, none of the Sellers, the Targets, the Subsidiaries or any of their Affiliates or Representatives or any employees, agents, consultants, advisors or representatives of the foregoing shall be required to remove or comply with any violations, notes, notices, orders, requirements or liens which (i) arise in connection with New York City Local Law 5/73, 10/80, 10/81, 62/81, 16/84, 80/85, 76/85 and 58 and equivalent or similar municipal laws and ordinances of the City of San Francisco or (ii) a tenant is required to remove or comply with pursuant to the terms of its Lease, and such violations, notes, notices, orders, requirements or liens shall not be deemed to be an objection to title.

For a period of six years following the Closing, the Buyer agrees that it will continue to cause each Target and Subsidiary to indemnify and hold harmless each present and former director, officer, employee and manager (each a "Covered Person") of such Target or Subsidiary against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Closing, whether asserted or claimed prior to, on or after the Closing, to the fullest extent that such Target or Subsidiary is permitted under the Laws of its applicable jurisdiction of organization and required pursuant to its certificate of incorporation, certificate of formation, certificate of limited partnership, bylaws, limited liability company agreement, limited partnership agreement or other organizational documents in effect on the date hereof to indemnify such Covered Person (including the advancing of expenses as incurred to the fullest extent permitted under applicable Law); provided, however, that such Covered Person must provide an undertaking to such Target or Subsidiary (as appropriate) to repay such advances if it is ultimately determined by a court of competent jurisdiction (which determination shall have become final) that such Covered Person is not entitled to indemnification; and provided further, however, that, to the fullest extent permitted: (i) the Buyer or such Target or Subsidiary shall

have the right to assume the defense thereof, and neither the Buyer nor any Target or Subsidiary shall be liable to any such Covered Person for any legal expenses of other counsel or any other expenses subsequently incurred by such Covered Person in connection with the defense thereof, except that if the Buyer or such Target or Subsidiary elects not to assume such defense or counsel for such Covered Person advises that there are issues which raise conflicts of interest between the Buyer or such Target or Subsidiary and such Covered Person, such Covered Person may retain counsel satisfactory to it, and the Buyer or such Target or Subsidiary shall pay all reasonable fees and expenses of such counsel for such Covered Person promptly as statements therefor are received; provided, however, that whether or not the Buyer or such Target or Subsidiary assumes the defense of a Covered Person, the Buyer or such Target or Subsidiary shall not admit any liability with respect to, or settle, compromise or discharge, or offer to settle, compromise or discharge, such claim without such Covered Person's prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, unless such settlement or compromise includes as one of its terms the complete release of the Covered Person without any admission of guilt; and provided further, however, that the Buyer and such Target or Subsidiary shall be obligated pursuant to this Section 5.10 to pay for only one firm or counsel for all Covered Persons in any jurisdiction unless the use of one counsel for such Covered Persons would present such counsel with a conflict of interest, provided that the fewest number of counsel necessary to avoid conflicts of interest shall be used; (ii) such Covered Persons will reasonably cooperate in the defense of any such matter; and (iii) none of the Buyer or any Target or Subsidiary shall be liable for any settlement effected without the prior written consent of the Buyer or such Target or Subsidiary, as applicable. For the avoidance of doubt, nothing in this Section 5.10 shall supersede or modify the Indemnification Agreement or in any way affect the parties' obligations pursuant to the Indemnification Agreement.

Section 5.11 Release. Effective as of the Closing Date and except as otherwise provided by Section 5.10 and except as set forth in the Indemnification Agreement, the Sellers do hereby, on behalf of themselves and each of their respective Affiliates, successors and assigns, release and forever discharge each of the Targets, the Subsidiaries, their Affiliates and their respective successors and assigns, and all Persons who at any time prior to the Closing Date have been stockholders, directors, officers or employees of any Target or any of the Subsidiaries (in each case, in their respective capacities as such), and their respective heirs, executors, administrators, successors and assigns, from any and all liabilities whatsoever, whether at law or in equity (including any right of contribution), whether arising under any contract or agreement, by operation of law or otherwise, existing or arising from any acts or events occurring or failing to occur or alleged to have occurred or to have failed to occur or any conditions existing or alleged to have existed at or before the Closing Date, including in connection with the transactions and all other activities contemplated by this Agreement.

Section 5.12 Legal Action. From the date hereof and continuing through Closing, the Sellers shall, and shall cause their respective Affiliates to, provide the Buyer with copies of all pleadings, Orders, requests for information or meetings, correspondence and other similar materials received or sent by them relating to the Legal Action or any related proceedings, Actions or claims promptly upon receipt or delivery thereof, as applicable. In addition, the Sellers agree to provide the Buyer with notice of any actual or proposed hearing or other proceeding relating to the Legal Action or any related proceedings, Actions or claims promptly upon receipt or prior to delivery by any of the Sellers, any Target or any Subsidiary of notice

thereof. At least 24 hours prior to submission, the Sellers shall provide the Buyer with the right to review and to consult with the Sellers, the Targets, the Subsidiaries and their counsel on any pleadings or other submissions relating to the Legal Action or other related proceeding, Action or claim, unless the same involves an emergency filing, in which case the Sellers shall provide the Buyer the right to review and to consult at least 12 hours prior to submission. If counsel for the Buyer objects to any such filing or other submission, the parties and their respective counsel shall confer in good faith in an effort to reach agreement on such filing or other submission, and the Sellers shall not submit, or permit the submission of, any such filing or other submission without the Buyer's prior approval, which will not be unreasonably withheld or delayed. The Sellers also agree to apprise the Buyer on the status of the Legal Action and any related proceedings, Actions or claims as and when requested and promptly upon the Sellers' becoming aware of any material development therein.

Section 5.13 Estoppel Certificates. Within 10 Business Days after the date hereof, the Sellers shall cause the Subsidiary that owns the relevant Property to prepare and deliver to each of the tenants at that Property (with a blind copy to the Buyer concurrently therewith), an estoppel certificate in the applicable form attached hereto as Exhibit 5.13, in each case completed to reflect the terms of such tenant's lease and related tenancy (each, an "Estoppel Certificate"). Subject to the next sentence, the Sellers shall (i) direct the building manager for the relevant Property to attempt to obtain a completed and original countersigned Estoppel Certificate from each such tenant; and (ii) deliver to the Buyer a copy of each completed and countersigned Estoppel Certificate and any other response or related correspondence from each such tenant (any such Estoppel Certificates and information contained therein received by the Buyer shall be deemed to be Information (as defined in the Confidentiality Agreements)). The parties understand and agree that receipt of completed Estoppel Certificates from the above-referenced tenants is not a condition precedent to any of the Buyer's obligations as set forth in this Agreement. The Buyer shall not contact any of the tenants of the Properties with respect to their Leases or the transactions contemplated herein prior to the Closing without the prior written consent of the Sellers, which consent may be withheld in the Sellers' sole discretion. Except as provided in this Section 5.13, the Sellers shall have no other obligations hereunder or under any Ancillary Agreements with respect to estoppel certificates.

Section 5.14 Personal Property. The Sellers shall not, and shall cause the Targets and Subsidiaries not to, remove any personal property from the Properties.

Section 5.15 Other Transfers of Condominiums. The Sellers shall use their commercially reasonable efforts to complete the sales of the Condominiums on or prior to March 31, 2007. If HWA I or HWA II continue to own any of the Condominiums on March 30, 2007, the Sellers shall cause HWA I and HWA II to sell their interests in the Condominiums to HWA III on March 31, 2007 for an amount equal to 95% of the contract price for such Condominiums as of the date hereof. Any gain realized upon the sale of any interests in the Condominiums shall be recognized in the tax year ending March 31, 2007, and any unpaid income tax liabilities associated with such gain shall constitute "Other Liabilities" and shall be borne by the Sellers in accordance with Sections 2.6 and 2.7 hereof.

(a) The Sellers shall cause the Targets and Subsidiaries to satisfy, cure or otherwise cause the elimination of any Voluntary Title Matters prior to the Closing.

(b) Either (i) the Sellers shall cause the Targets and Subsidiaries to satisfy, cure or otherwise cause the elimination of any Monetary New Title Matters prior to the Closing or (ii) elect to treat such Monetary New Title Matters as "Other Liabilities" (pursuant to clause (vi) of that definition) to be borne by the Sellers in accordance with Sections 2.6 and 2.7 hereof; provided, however, that if the aggregate amount of all Monetary New Title Matters (but specifically excluding for purposes of this subparagraph any Voluntary Title Matters, which are addressed in clause (a) above and which shall not be considered when determining the dollar amounts set forth in this paragraph 5.16(b)) exceeds $15,000,000 (such excess amount, the "Excess Amount"), the Sellers shall have the option, but shall have no obligation, to cause the Targets and Subsidiaries to satisfy, cure or otherwise cause the elimination of, or elect to treat as an "Other Liability," such Excess Amount. If the Sellers are not willing to cause the removal of, or elect to treat as an "Other Liability," the Excess Amount, then the Sellers shall give written notice of the same to the Buyer promptly upon the Sellers first becoming aware of the Excess Amount (which notice will state the Sellers' unwillingness to remove, or to treat as an "Other Liability," the Excess Amount prior to the Closing, it being understood that (x) the Sellers will not be required to remove, or elect to treat as an "Other Liability," any Excess Amount unless the Sellers separately undertake to do so in their discretion, and also that (y) in any event the Sellers will, in every instance, be responsible for causing the removal of all Voluntary Title Matters). If the Sellers are not willing to remove, or elect to treat as an "Other Liability," the Excess Amount, the Buyer shall have the right, in the Buyer’s discretion, either to (1) waive the Excess Amount and proceed to Closing (in which case the Sellers will only be required to remove or treat as an "Other Liability" the first $15,000,000 of Monetary New Title Matters, and to remove such portion of the Excess Amount as the Sellers, and the Buyer shall agree) or (2) terminate this Agreement. The Buyer shall exercise its right to elect either clause (1) or (2) of the foregoing sentence by providing written notice of such election to the Sellers within the earlier of 20 days after receipt of notice from the Sellers as set forth above or the then-scheduled Closing Date.

Section 5.17 Preparation of Financial Statements. The Sellers agree that they will assist the Buyer, at the Buyer's expense, to produce financial statements for the Properties satisfying the requirements of Regulation S-X promulgated under the U.S. securities laws as and when needed to satisfy the Buyer's public reporting obligations in connection with the transactions contemplated hereby, and permit the Buyer's independent registered public accounting firm access to the books and records of the Targets and the Subsidiaries for the purpose of conducting an audit of such financial statements. The Sellers agree to use commercially reasonable efforts to cause the Targets and Subsidiaries to give the Buyer and its accountants access to such of its books and records relating to the Targets, Subsidiaries and Properties and to direct their internal and external property management personnel to cooperate with the Buyer and its accountants, in each case to the extent necessary to enable the Buyer and the accountants to produce and, where applicable, audit financial statements for the Properties. Notwithstanding anything to the contrary contained in this Section 5.17, the Buyer acknowledges that the Sellers and the general partners of the Hudson Waterfront Partnerships have limited resources and are engaged in the preparation of the audited financial statements for the Properties for the 2006 fiscal year as required by the Debt Agreements. Accordingly, the Buyer shall use its commercially reasonable efforts to minimize any interference with the preparation of such financial statements.

Section 5.18 Termination of 401(k) Plan. Prior to the Closing, the Sellers shall execute the 401(k) Resolutions pursuant to which the general partner of HWA I shall terminate each Employee Plan that includes a Code Section 401(k) arrangement.

Section 5.19 Termination of Management Agreements. Within five Business Days of the date hereof, the Sellers shall (i) cause HWA I to deliver a notice of termination of the Asset Services Agreement, dated as of March 1, 2006, between HWA I and Shorenstein Realty Services, L.P, pursuant to Section 4.1(c) thereof and (ii) cause HWA 555 Owners, LLC to deliver a notice of termination of the Building Management Agreement, dated as of March 1, 2006, by and between HWA 555 Owners, LLC and Shorenstein Realty Services, L.P, pursuant to Section 5.1(c) thereof. The Sellers make no representations with respect to the timeliness or effect of such notice and shall have no liability to the Buyer for any claims resulting therefrom.

Section 5.20 Conversion of Shares. Prior to the Closing, the Sellers shall cause all of the Shares that are bearer shares to be exchanged for registered shares in the applicable Targets, and the Sellers shall cause their Representatives to replace any Shares that have been lost, stolen or destroyed prior to such conversion.

Section 5.21 Further Assurances. At any time following the Closing, the Sellers shall and shall cause their Affiliates to promptly execute, acknowledge and deliver any other assurances or documents reasonably requested by the Buyer to vest more effectively in the Buyer ownership of the Shares and the Partnership Intercompany Notes; provided, that the Buyer shall pay any actual and reasonable third-party fees, costs or expenses incurred by the Sellers in connection therewith and that such assurances or other documents do not create any further obligation on or impair any right of the Sellers.

Section 6.1 Cooperation. The Sellers and the Buyer shall provide each other with such cooperation and information as either of them reasonably may request of the other in filing any Tax Return or claim for refund, determining a liability for Taxes or a right to a refund of Taxes, and participating in or conducting any audit or other proceeding in respect of Taxes. The Sellers and the Buyer shall make themselves (and their respective Representatives and employees) available on a basis mutually convenient to both parties to provide explanations of any Tax Returns or information provided under this Section 6.1. Each of the Sellers and the Buyer shall retain all Tax Returns in their possession relating to Tax matters relevant to the Targets and Subsidiaries for each taxable period first ending after the Closing Date and for all prior taxable periods until the later of (a) the expiration of the statute of limitations of the taxable periods to which such Tax Returns relate, without regard to extensions except to the extent notified by the other party in writing of such extensions for the respective Tax periods, or (b) six years following the due date (without extension) for such Tax Returns. After such time, before the Sellers or the Buyer shall dispose of any such Tax Returns in its possession (or in the possession of its Affiliates), the other party shall be given the opportunity, after 30 days' prior written notice, to remove and retain all or any part of such Tax Returns as such other party may select (at such other party's expense). Any information obtained under this Section 6.1 shall be kept confidential as provided in the letter agreement regarding confidentiality being entered into

between the Buyer and the Sellers concurrently herewith (including the exceptions permitted therein), except as may be otherwise necessary in connection with the filing of Tax Returns or claims for refund or in conducting an audit or other proceeding.

Section 6.2 Taxes Generally. All Tax Returns of the Targets or Subsidiaries not required to be filed on or before the date hereof will, to the extent required to be filed on or before the Closing Date, be filed (or caused to be filed) by the Sellers when due and will be prepared (or caused to be prepared) consistent with past practice and in accordance with all applicable Laws. On or before the Closing Date, the Sellers shall prepare and file (or cause to be prepared and filed) Form 1065 for HWA I and Form 1120 for the Subsidiaries that are the direct or indirect partners of HWA I (and, in each case, any state and local equivalent Tax Returns) for the fiscal year ending March 31, 2007 (the "HWA I Tax Returns"). To the extent Tax Returns of the Targets or Subsidiaries are required to be filed after the Closing Date, but relate to taxable periods ending on or before the Closing Date, the Seller will prepare (or cause to be prepared) such Tax Returns consistent with past practice and in accordance with all applicable Laws, and will deliver such Tax Returns to the Buyer for filing. The Sellers will cause to be paid by the applicable Target or Subsidiary the amount of Taxes shown as due on the Tax Returns that are filed by the Seller pursuant to this Section 6.2. The Buyer shall cause the relevant Subsidiaries and/or Targets to file all other Tax Returns and, subject to the Sellers' obligation to indemnify the Buyer pursuant to Section 6.3, shall cause the relevant filing entities to pay all Taxes shown as due on such Tax Returns; provided, however, that any Tax Return prepared and filed by or at the direction of the Buyer that includes any period (or portion thereof) on or before the Closing Date (including a Straddle Period, as defined below) (x) shall report the Tax consequences of the property exchanges entered into by HWA III, HWA IV and HWA V in a manner consistent with the reporting of such exchanges on Form 1065 filed with respect to the fiscal year ending March 31, 2006; (y) shall be prepared consistent with past practices of the entity for which such Tax Return is filed, but only to the extent such past practices are in accordance with applicable Laws; and (z) shall be delivered to the Sellers for review no later than 10 days prior to filing and shall be revised to reflect any reasonable comments by the Sellers.

(a) All Taxes relating to the Targets and the Subsidiaries for any taxable year or period (or portion thereof) ending on or prior to the Closing (including, for the avoidance of doubt, any Taxes arising from the sale of the Targets pursuant to this Agreement, the dissolution of HWA II and any corresponding assignments or distributions pursuant to Section 5.2 and the transactions described in Section 5.3) (the "Pre-Closing Tax Period") will be the responsibility of the Sellers, and the Sellers shall jointly and severally indemnify and hold the Buyer, the Targets and the Subsidiaries harmless with respect thereto. Except as otherwise provided herein, all Taxes relating to the Targets and the Subsidiaries for any taxable year or period (or portion thereof) beginning after the Closing (the "Post-Closing Tax Period") will be the responsibility of the relevant Target or Subsidiary and not of the Sellers. The Sellers shall also be liable, and shall jointly and severally indemnify the Buyer, the Targets and the Subsidiaries, for all Taxes imposed on any Target or any Subsidiary as a result of a failure of any of the representations and warranties in Section 3.14 to be true, and such representations and warranties shall survive for the relevant statute of limitations period for the Taxes in question. Notwithstanding anything in this Agreement to the contrary, to the extent Taxes relating to the Targets or the Subsidiaries for

any Pre-Closing Tax Period are attributable to the Buyer's adoption, modification or termination of any Tax election, Tax year or method of Tax accounting, on or after the Closing Date (other than as expressly contemplated by this Agreement, required by applicable Laws or mandated by a Governmental Authority), such Taxes shall not be the responsibility of the Sellers, and the Sellers shall have no indemnification obligation for such Taxes. Any prepaid Taxes or estimated Tax payments made by a Target or a Subsidiary (or by the Sellers on behalf of a Target or a Subsidiary) on or prior to the Closing Date shall be allocated to the Sellers in determining the Sellers' obligations hereunder (including any Pre-Closing Adjustment Amount or Final Adjustment Amount). For certainty of interpretation, and for purposes of this Section 6.3(a), Taxes for a Pre-Closing Tax Period attributable to any public disclosure by the Buyer or its Affiliates that is required as a result of FASB Interpretation No. 48 shall remain the responsibility of the Sellers, and the Sellers shall have an indemnification obligation for such Taxes.

(b) Whenever it is necessary for purposes of this Article VI to determine the liability for Taxes of any Target or any Subsidiary for any taxable period beginning on or prior to and ending after the Closing Date (a "Straddle Period"), the determination shall be made by assuming that the Target or the Subsidiary (as the case may be) had a taxable year or period which ended at the close of business on the Closing Date, except that exemptions, allowances or deductions that are calculated on an annual basis (such as the deduction for depreciation) shall be apportioned on a time basis.

Section 6.4 Filing of Amended Tax Returns. Any amended Tax Return or claim for Tax refund with respect to a Target or Subsidiary to be filed after the Closing for a Pre-Closing Tax Period requires the consent of both the Sellers and the Buyer. The Buyer shall not make an election under Section 338(g) of the Code with respect to the acquisition of the Targets without the prior written consent of the Sellers.

(a) To the extent any refunds, interest or credits with respect to Taxes of a Target or a Subsidiary are attributable to a Pre-Closing Tax Period, such refunds, interest or credits shall be for the account of the Sellers. Notwithstanding the foregoing, any such refunds, interest, credits or offsets of Taxes shall be for the account of the Buyer to the extent such refunds, interest, credits or offsets of Taxes are (A) attributable (determined on a marginal basis) to the carryback from a taxable year or period that begins after the Closing Date of items of loss, deduction or credit, or other Tax items of any Target or any Subsidiary (or any of their respective Affiliates, including the Buyer) or (B) included in the Other Assets.

(b) To the extent that any refunds, interest or credits with respect to Taxes of a Target or a Subsidiary are attributable to a Post-Closing Tax Period, such refunds, interest or credits shall be for the account of the Buyer. To the extent any refunds, interest or credits with respect to Taxes paid by a Target or a Subsidiary are attributable to a Straddle Period, such refunds, interest or credits with respect to Taxes shall be apportioned between the Sellers and the Buyer based on the appropriate allocation method set forth in Section 6.3. The Buyer shall forward to the Sellers or reimburse the Sellers for any such refunds, interest or credits that are for the account of the Sellers within 10 Business Days from receipt thereof by the Buyer or any of its

Affiliates, provided that solely with respect to any refunds, interest or credits related to Taxes, such amounts shall be subject to a right of set-off in respect of any claim a Buyer Indemnified Party may have against the Sellers.

(a) The Buyer shall promptly notify the Sellers in writing upon receipt by the Buyer, any Target or any Subsidiary of notice of any pending or threatened federal, state, local or foreign income or franchise Tax audits or assessments which may materially affect the Tax liabilities of any Target or any Subsidiary for which the Sellers would be required to indemnify the Buyer pursuant to Article VI, provided, however, that failure to comply with this provision shall not affect the Buyer's right to indemnification hereunder except to the extent such failure has materially prejudiced the Sellers' ability to defend the audit or assessment.

(b) The interests of the Sellers in any Tax audit or administrative or court proceeding to the extent relating to taxable periods ending on or before the Closing Date or relating to any Straddle Period shall be determined based on procedures mutually agreed upon between the Sellers and the Buyer.

Section 6.7 Payment of Transfer Taxes. The Buyer shall pay all Transfer Taxes owing in respect of the transfer of the Shares from the Sellers to the Buyer as contemplated herein. The Sellers agree to cooperate with the Buyer in the preparation of and, where required, by joining as signatory to, the Tax Returns required in connection with the foregoing Transfer Taxes.

Section 6.8 Adjustment to Purchase Price. Any payment under article vi will be an adjustment to the purchase price to the extent permitted by applicable law.

(a) For purposes of this Article VII, the following terms shall have the following meanings:

"Major Casualty" means one or more fires or other casualties to any of the Properties that results in (1) aggregate Restoration Costs in excess of $45,000,000 at a Property, as determined on a Property by Property basis, and not on an aggregate basis among all of the Properties, (2) tenants holding Leases of more than 20% of the total rentable space in the applicable Property having a right to terminate their Leases (it being understood that any tenant that subsequently loses or waives such right to terminate in writing shall not be included in such calculation) or (3) receipt of notice from the Lender under the 1290 Senior Debt Agreement that the casualty (or, if applicable, condemnation) has resulted in an Event of Default (as defined in the 1290 Senior Debt Agreement) or otherwise allows the loan made pursuant to the 1290 Senior Debt Agreement to be declared due and payable (unless such Lender shall have waived in writing all such rights).

"Material Portion" shall mean a fee, leasehold, easement or other interest in any Property that reduces the value of such Property by more than $45,000,000.

"Restoration Costs" means, as of any date with respect to any fire or other casualty, the estimated total cost, as reasonably determined by an architect or engineer selected by Sellers and reasonably approved by the Buyers, to be incurred, from and after such date, to repair or restore the damage to any of the Properties caused by such fire or other casualty.

(b) If, between the date hereof and the Closing, there shall occur one or more fires or other casualties affecting any or all of the Properties, or any portions thereof and the fires and/or other casualties do not constitute a Major Casualty, then (i) no party shall have any right to terminate this Agreement as a result thereof and (ii) if such fires or other casualties resulted in damages to the Properties, the Buyer shall acquire the Targets without reduction of or offset against the Purchase Price or any other claim against the Sellers except as may be expressly provided below. At Closing, the Sellers shall pay to the Buyer all insurance proceeds received by the Sellers or any of their Affiliates (other than a Target or a Subsidiary) in connection with such fires or other casualties (other than any business interruption or rent loss insurance attributable to the period prior to the Closing) and shall assign to the Buyer the Sellers' right, if any, to receive any insurance proceeds payable to the Sellers or any of their Affiliates (other than a Target or a Subsidiary) as a result of such fires or other casualties, provided, however, that the Sellers shall be entitled to retain (to the extent previously paid to the Sellers), and shall not be obligated to assign the right to receive (to the extent not previously paid to the Sellers), an amount of such insurance proceeds equal to the Sellers' expenses, if any, incurred by the Sellers or any of their Affiliates (including the Targets and Subsidiaries) in collecting such proceeds and undertaking any repairs of the Properties. Additionally, the Purchase Price shall be reduced by the deductible amount under such insurance policies.

(c) If, between the date hereof and the Closing, there shall occur a fire or other casualty affecting the Properties, and the damage to any of the Properties (as determined on a Property by Property basis and not on an aggregate basis among all the Properties) results in a Major Casualty to such Property, then the Buyer shall have the option, to be exercised by notice given to the Sellers (a "Casualty Termination Notice") within 15 days after the date the Sellers deliver written notice to the Buyer of such fire or other casualty (including, in such notice, an affirmative statement that it is being given pursuant to this Section 7.1(c) and that if the Buyer fails to respond within 15 days of receipt the same will be deemed a waiver of the Buyer's termination right under this Agreement), to terminate this Agreement in its entirety. If the Buyer shall deliver a Casualty Termination Notice, then this Agreement shall terminate in its entirety (subject to Section 10.2) immediately upon receipt by the Sellers of such termination notice. If the Buyer shall elect to terminate this Agreement by delivering a Casualty Termination Notice, then (x) the Buyer shall be entitled to the return of the Escrow Fund and (y) no party hereto shall have any further obligations or liabilities to the other under this Agreement, except for those which expressly survive the termination of this Agreement as set forth in Section 10.2. If the Buyer does not elect to terminate this Agreement as provided in this Section 7.1(c), then this Agreement shall remain in full force and effect and, to the extent applicable, the provisions of Section 7.1(b) above shall apply to such damage and any insurance proceeds payable in connection therewith.

(d) In no event shall the Sellers have any obligation to repair any damage or destruction to the Properties (except as provided in Section 5.1 of this Agreement), but the Sellers shall have the right to do so and utilize insurance proceeds for such purpose.

(a) If, between the date hereof and the Closing, and as determined on a Property by Property basis, any condemnation or eminent domain proceedings are initiated which would result in the taking of all or any Material Portion of a Property or that would result in the circumstances described in clause (2) or clause (3) of the definition of Major Casualty, then the Buyer may elect to terminate this Agreement by giving written notice of its election to the Sellers within 15 days after receiving written notice of such prospective taking (including, in such notice, an affirmative statement that it is being given pursuant to this Section 7.2(a) and that if the Buyer fails to respond within 15 days of receipt the same will be deemed a waiver of the Buyer's termination right under this Agreement). If this Agreement shall be so terminated, then (i) the Buyer shall be entitled to the prompt return of the Escrow Fund, and (ii) none of the parties hereto shall have any further obligations or liabilities to any other parties under this Agreement, except for those which-expressly survive the termination of this Agreement as set forth in Section 10.2. If this Agreement is not so terminated as aforesaid, then the parties hereto shall proceed to the Closing without reduction of or offset against the Purchase Price (but the Sellers agree that at Closing the Sellers will assign any and all right to recover proceeds in respect of any such condemnation or other proceedings to the Buyer in a form of assignment reasonably acceptable to the Buyer and if any such proceeds shall be paid to or become payable to any Seller or any Affiliate thereof, other than a Target or a Subsidiary, the Sellers agree to deliver, or cause the same to be delivered, directly to the Buyer promptly upon receipt) and the Buyer shall have no other claim against the Sellers. In such event, at the Closing all of the Sellers' right, title and interest in and to any condemnation proceeds paid or payable in connection therewith shall be paid or assigned, as the case may be, to the Buyer.

(b) If, between the date hereof and the Closing, any condemnation or eminent domain proceedings are initiated which would result in the taking of less than a Material Portion of a Property, then the Buyer may not terminate this Agreement as a result thereof and the parties shall proceed to the Closing without reduction of or offset against the Purchase Price (but the Sellers agree that at Closing the Sellers will assign any and all right to recover proceeds in respect of any such condemnation or other proceedings to the Buyer in a form of assignment reasonably acceptable to the Buyer and if any such proceeds shall be paid to or become payable to any Seller or any Affiliate thereof, other than a Target or a Subsidiary, the Sellers agree to deliver, or cause the same to be delivered, directly to the Buyer promptly upon receipt) and the Buyer shall have no claim against the Sellers with respect thereto. In such event, at the Closing all of the right, title and interest of the Sellers in and to any condemnation proceeds paid or payable in connection therewith shall be paid or assigned to the Buyer.

Section 7.3 Waiver. The Sellers and the Buyer hereby waive the provisions of Section 5-1311 of the General Obligations Law of the State of New York and Section 1662(a) of the California Civil Code, and of any other similar law to the same or similar effect, and agree that the same shall not apply to this Agreement.

Section 8.1 General Conditions. The respective obligations of the Buyer and the Sellers to consummate the transactions contemplated by this Agreement shall be subject to the fulfillment, at or prior to the Closing, of each of the following conditions, any of which may, to the extent permitted by applicable Law, be waived in writing by either party in its sole discretion (provided, however, that such waiver shall only be effective as to the obligations of such party):

(a) No Governmental Authority shall have enacted, issued, promulgated, enforced or entered any Law (whether temporary, preliminary or permanent) that is then in effect and that enjoins, restrains, makes illegal or otherwise prohibits the consummation of the transactions contemplated by this Agreement or the Ancillary Agreements (an "Order ") and no such Order has been threatened.

(b) All material consents of, or registrations, declarations or filings with, any Governmental Authority required for the consummation of the transactions contemplated by this Agreement and the Ancillary Agreements shall have been obtained or filed.

Section 8.2 Conditions to Obligations of the Sellers. The obligations of the Sellers to consummate the transactions contemplated by this Agreement shall be subject to the fulfillment, at or prior to the Closing, of each of the following conditions, any of which may be waived in writing by the Sellers in their sole discretion:

(a) The representations and warranties of the Buyer contained in this Agreement or any Ancillary Agreement or any certificate delivered pursuant hereto shall be true and correct both when made and as of the Closing, or in the case of representations and warranties that are made as of a specified date, such representations and warranties shall be true and correct as of such specified date, except where the failure to be so true and correct (without giving effect to any limitation or qualification as to "materiality" (including the word "material") or "Material Adverse Effect" set forth therein) would not, individually or in the aggregate, have a Buyer Material Adverse Effect. The Buyer shall have performed all obligations and agreements and complied with all, covenants and conditions required by this Agreement or any Ancillary Agreement to be performed or complied with by it in all material respects prior to or at the Closing. The Sellers shall have received from the Buyer a certificate to the effect set forth in the preceding sentences, signed by a duly authorized officer thereof.

(b) The Sellers shall have received an executed counterpart of each of the Ancillary Agreements, signed by each party other than the Sellers, and each of the other closing deliverables required to be delivered by the Buyer pursuant to Section 2.4.

(c) The distributions set forth in Sections 5.2 and 5.3 of this Agreement shall have been consummated in accordance with the provisions thereof.

(d) The HWA I Tax Returns shall have been prepared and filed with the relevant taxing authorities as provided in Section 6.2.

Section 8.3 Conditions to Obligations of the Buyer. The obligations of the Buyer to consummate the transactions contemplated by this Agreement shall be subject to the fulfillment, at or prior to the Closing, of each of the following conditions, any of which may be waived in writing by the Buyer in its sole discretion:

(a) The representations and warranties of the Sellers contained in this Agreement or any Ancillary Agreement or any certificate delivered pursuant hereto shall be true and correct both when made and as of the Closing, or in the case of representations and warranties that are made as of a specified date, such representations and warranties shall be true and correct as of such specified date, except where the failure to be so true and correct (without giving effect to any limitation or qualification as to "materiality" (including the word "material") or "Material Adverse Effect" set forth therein) would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Notwithstanding the preceding sentence, the representations and warranties of the Sellers contained in Sections 3.4, 3.5 and 3.6 shall be true and correct in all respects both when made and as of the Closing. The Sellers shall have performed all obligations and agreements and complied with all covenants and conditions required by this Agreement or any Ancillary Agreement to be performed or complied with by them in all material respects prior to or at the Closing. Notwithstanding the preceding sentence, the covenants of the Sellers contained in Section 5.16 shall have been performed (subject to waiver by the Buyer) in all respects prior to the Closing. The Buyer shall have received from each of the Sellers a certificate to the effect set forth in the preceding sentences, signed by a duly authorized officer thereof.

(b) The Buyer shall have received an executed counterpart of each of the Ancillary Agreements, signed by each party other than the Buyer, and each of the other closing deliverables required to be delivered by the Sellers pursuant to Section 2.5.

(d) The Buyer shall have delivered the Non-Consolidation Opinion to the Lender (as defined therein) under the 1290 Senior Debt Agreement in a form acceptable to such Lender and the relevant ratings agencies.

(e) The distributions set forth in Sections 5.2 and 5.3 of this Agreement shall have been consummated in accordance with the provisions thereof.

(f) (i) There shall exist no Voluntary Title Matters, (ii) there shall exist no Monetary New Title Matters (other than such Monetary New Title Matters as have been waived by the Buyer as provided in Section 5.16(b) or which the Sellers have elected to treat as an "Other Liability" as provided in this Agreement) and (iii) there shall exist no Non-Monetary New Title Matters, that, individually and in the aggregate materially and adversely affect the value or use of the Property to which the Non-Monetary New Title Matter relates.

(g) The HWA I Tax Returns shall have been prepared and filed with the relevant taxing authorities as provided in Section 6.2.

Section 9.1 Survival of Representations, Warranties and Covenants. The representations and warranties of the Sellers and the Buyer contained in this Agreement shall survive the Closing until December 31, 2007, subject to extension as contemplated by Section 9.5(a); provided, however, that:

(a) the representations and warranties contained in Sections 3.4, 3.5 and 3.6 shall survive indefinitely;

(b) the representations and warranties contained in Sections 3.1, 3.2, 3.3, 3.7(c), 3.7(f), 3.16(a)(ii), 3.16(a)(v), 3.16(a)(viii), 3.16(a)(ix), 3.16(a)(x), 3.17, 3.22 and 3.25 shall survive until January 31, 2009; and

(c) in the absence of fraud, the representations and warranties contained in Sections 3.9, 3.15 and 3.23 shall not survive the Closing.

Section 9.2 Indemnification by the Sellers. Following the Closing, the Sellers shall, jointly and severally, save, defend, indemnify and hold harmless the Buyer and its Affiliates (including the Targets and the Subsidiaries), officers, directors, employees, agents, successors and assigns (collectively, the "Buyer Indemnified Parties") from and against any and all losses, damages, liabilities, deficiencies, claims, interest, awards, judgments, penalties, costs and expenses (including reasonable attorneys' fees, costs and other out-of-pocket expenses incurred in investigating, preparing or defending the foregoing) (hereinafter collectively, "Losses") to the extent arising out of or resulting from:

(a) any breach of any representation or warranty made by a Seller or the Sellers contained in this Agreement or any Ancillary Agreement or any certificate delivered pursuant hereto (for purposes of determining the amount of any Losses (but not for determining if a breach of any representation or warranty has occurred) pursuant to this Section 9.2(a), all representations and warranties shall be read without any "material", "materiality" and "material adverse effect" qualifications);

(b) any breach of any covenant or agreement by a Seller or the Sellers contained in this Agreement; and

(c) any indemnification or other obligation of the Targets or the Subsidiaries arising under the Extell Purchase Agreement and, any other residual liability any of the Targets or Subsidiaries may have as a result of owning or operating the property exchanged pursuant to the Extell Purchase Agreement or any other property any of the Targets and the Subsidiaries may have owned or leased prior to purchasing the Properties. For the avoidance of doubt, nothing in this paragraph (c) shall supersede or modify the Indemnification Agreement or in any way affect the parties' obligations pursuant to the Indemnification Agreement.

Section 9.3 Indemnification by the Buyer. Following the Closing, the Buyer shall save, defend, indemnify and hold harmless the Sellers and their Affiliates, officers, directors,

employees, agents, successors and assigns (collectively, the "Seller Indemnified Parties") from and against any and all Losses to the extent arising out of or resulting from:

(a) any breach of any representation or warranty made by the Buyer contained in this Agreement or any Ancillary Agreement or any certificate delivered pursuant hereto;

(b) any breach of any covenant or agreement by the Buyer contained in this Agreement; and

(c) any claim or cause of action by any Person against any Seller Indemnified Party with respect to the operations of the Targets or the Subsidiaries following the Closing (but subject to the Targets' and Subsidiaries' indemnification obligations pursuant to Section 5.10), except for claims or causes of action with respect to which the Sellers are obligated to indemnify the Buyer Indemnified Parties pursuant to Section 9.2.

(a) In order for a Buyer Indemnified Party or Seller Indemnified Party (the "Indemnified Party") to be entitled to any indemnification provided for under this Agreement as a result of a Loss or a claim or demand made by any Person against the Indemnified Party (a "Third Party Claim"), such Indemnified Party shall deliver notice thereof to the party against whom indemnity is sought (the "Indemnifying Party") promptly after receipt by such Indemnified Party of written notice of the Third Party Claim, describing in reasonable detail the facts giving rise to any claim for indemnification hereunder, the amount or method of computation of the amount of such claim (if known) and such other information with respect thereto as the Indemnifying Party may reasonably request. The failure to provide such notice, however, shall not release the Indemnifying Party from any of its obligations under this Article IX except to the extent that the Indemnifying Party is materially prejudiced by such failure.

(b) The Indemnifying Party shall have the right, upon written notice to the Indemnified Party within 30 days of receipt of notice from the Indemnified Party of the commencement of such Third Party Claim, to assume the defense thereof at the expense of the Indemnifying Party with counsel selected by the Indemnifying Party and reasonably satisfactory to the Indemnified Party. If the Indemnifying Party assumes the defense of such Third Party Claim, the Indemnified Party shall have the right to employ separate counsel and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party. If the Indemnifying Party assumes the defense of any Third Party Claim, the Indemnified Party shall cooperate with the Indemnifying Party in such defense and make available to the Indemnifying Party all witnesses, pertinent records, materials and information in the Indemnified Party's possession or under the Indemnified Party's control relating thereto as is reasonably required by the Indemnifying Party. Whether or not the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, or offer to settle, compromise or discharge, such Third Party Claim without the Indemnifying Party's prior written consent.

(c) In the event any Indemnified Party should have a claim against any Indemnifying Party hereunder that does not involve a Third Party Claim being asserted against or

sought to be collected from such Indemnified Party, the Indemnified Party shall deliver notice of such claim promptly to the Indemnifying Party, describing in reasonable detail the facts giving rise to any claim for indemnification hereunder, the amount or method of computation of the amount of such claim (if known) and such other information with respect thereto as the Indemnifying Party may reasonably request. The failure promptly to provide such notice, however, shall not release the Indemnifying Party from any of its obligations under this Article IX except to the extent that the Indemnifying Party is materially prejudiced by such failure. The Indemnified Party shall reasonably cooperate and assist the Indemnifying Party in determining the validity of any claim for indemnity by the Indemnified Party and in otherwise resolving such matters. Such assistance and cooperation shall include providing reasonable access to and copies of information, records and documents relating to such matters.

(a) No claim may be asserted against either party for breach of any representation, warranty or covenant contained herein, unless written notice of such claim is received by such party, describing in reasonable detail the facts and circumstances with respect to the subject matter of such claim on or prior to the date on which the representation, warranty or covenant on which such claim is based ceases to survive as set forth in Section 9.1, in which case such representation, warranty or covenant shall survive as to such claim until such claim has been finally resolved.

(i) the Sellers shall not be liable to any Buyer Indemnified Party for any claim for indemnification pursuant to Sections 9.2(a) and (b) unless and until the aggregate amount of indemnifiable Losses that may be recovered from the Sellers equals or exceeds $5,000,000, as this amount may be reduced from time to time as provided in Section 2.6 of the Indemnification Agreement (as so reduced, the "Basket Amount"), in which case the Sellers shall be liable only for the Losses in excess of the Basket Amount (i.e., claims pursuant to Section 9.2(a) are subject to a one-time deductible equal to the Basket Amount); provided, however, that no Losses may be claimed by any Buyer Indemnified Party or shall be reimbursable by the Sellers or shall be included in calculating the aggregate Losses for purposes of this clause (i) other than Losses in an amount that exceeds $50,000 resulting from any single claim or aggregated claims arising out of the same or related facts, events or circumstances (the "Minimum Loss Amount"; it being understood that any Losses that do exceed the Minimum Loss Amount will be recoverable in full – i.e., the Minimum Loss Amount is a filter but not a deductible); and provided further, however, that claims for indemnification: (A) for breaches of any representation or warranty contained in Section 3.18 or (B) provided by Article VI with respect to income taxes (it being agreed that any claims for indemnification for any Taxes, other than income taxes and withholding taxes and all interest, penalties and expenses relating thereto, shall be subject to the Basket Amount and Minimum Loss Amount) shall not be subject to any of the limitations set forth in this Section 9.5(b)(i);

(ii) the Sellers shall not be obligated to indemnify any Buyer Indemnified Party with respect to any Loss to the extent that the Buyer was compensated for such Loss in the calculation of the adjustment of the Base Purchase Price, if any, as finally determined pursuant to Section 2.7; and

(iii) no party hereto shall have any liability under Sections 9.2 or 9.3 of this Agreement for any punitive, consequential, special or indirect damages, including business interruption, loss of future revenue, profits or income, or loss of business reputation or opportunity relating to the breach or alleged breach of this Agreement.

(c) For all purposes of this Article IX, "Losses" shall be net of the actual dollar benefit payable to the Buyer or the affected Subsidiaries pursuant to any insurance or other recoveries payable under the Insurance Polices (or replacements thereof) obtained by the Sellers, the Targets or the Subsidiaries prior to the Closing, for which all premiums were either paid in full prior to the Closing or reflected as an "Other Liability," to the Indemnified Party or its Affiliates in connection with the facts giving rise to the right of indemnification. The Buyer and the Sellers shall, or shall cause the applicable Indemnified Party to, use commercially reasonable efforts to seek full recovery under all Insurance Policies (or replacements thereof) obtained by the Sellers, the Targets or the Subsidiaries prior to the Closing, for which all premiums were either paid in full prior to the Closing or reflected as an "Other Liability," covering any Loss to the same extent as they would if such Loss were not subject to indemnification hereunder.

(a) The Buyer hereby agrees that the Escrow Fund shall provide the sole and exclusive remedy for the Buyer Indemnified Parties with respect to any indemnification claim asserted hereunder other than (i) claims for Losses resulting from breaches of Sections 3.4, 3.5, 3.6 and 3.18, (ii) indemnification claims provided by Article VI and (iii) indemnification for the Sellers' obligations under the Indemnification Agreement, for which, in each case, the Buyer may seek indemnification as provided herein from the Sellers, jointly and severally, (A) in the case of (i) and (ii) for any amounts in excess of the amount remaining in the Escrow Fund and (B) in the case of (iii) for any amounts (it being understood that solely with respect to (iii), the Buyer is not required to exhaust funds in the Escrow Fund before seeking indemnification for such claims against the Sellers directly). If a Buyer Indemnified Party is entitled to indemnification under this Article IX and the Buyer so requests, the Buyer and the Sellers shall jointly instruct the Escrow Agent to pay to the Buyer Indemnified Party from the Escrow Fund the amount of such Losses by wire transfer of immediately available funds in accordance with the terms of the Escrow Agreement.

(b) The Buyer and the Sellers agree that, if any amounts in excess of $50,000,000 remain in the Escrow Fund as of the close of business on December 31, 2007, the Buyer and the Sellers promptly shall instruct the Escrow Agent to pay such funds (less any amounts then subject to any claim by any Buyer Indemnified Party against the Sellers) to the Sellers. The Buyer and the Sellers agree that any amounts remaining in the Escrow Fund after December 31,

2007 shall only be available to satisfy (i) claims for Losses resulting from breaches of the representations set forth in Sections 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7(c), 3.7(f), 3.16(a)(ii), 3.16(a)(v), 3.16(a)(viii), 3.16(a)(ix), 3.16(a)(x), 3.17, 3.22 and 3.25 of this Agreement, (ii) indemnification claims provided by Article VI of this Agreement, (iii) the Sellers' obligations under the Indemnification Agreement and (iv) any claims still outstanding hereunder as of December 31, 2007.

(c) The Buyer and the Sellers agree that, if any amounts in excess of $25,000,000 remain in the Escrow Fund as of the close of business on January 31, 2009, the Buyer and Sellers promptly shall instruct the Escrow Agent to pay such funds (less any amounts then subject to any claim by any Buyer Indemnified Party against the Sellers) to the Sellers. The Buyer and the Sellers agree that any amounts remaining in the Escrow Fund after January 31, 2009 shall only be available to satisfy (A) indemnification claims provided by Article VI, (B) the Sellers' obligations under the Indemnification Agreement and (C) any claims still outstanding hereunder as of January 31, 2009. If the Legal Action has been finally resolved on or before December 31, 2009, then on or after December 31, 2009 Buyer and the Sellers promptly shall instruct the Escrow Agent to pay the remaining amount of the Escrow Fund (less any amounts then subject to any claim by any Buyer Indemnified Party against the Sellers) to the Sellers. Any amounts remaining in the Escrow Fund after December 31, 2009 shall only be available to satisfy (A) indemnification claims provided by Article VI, (B) the Sellers' obligations under the Indemnification Agreement and (C) any claims still outstanding hereunder as of December 31, 2009.

(d) The Buyer and the Sellers agree that promptly after the later of December 31, 2009 and the date on which the Legal Action is no longer pending (whether by settlement or final judgment) the Buyer and the Sellers shall instruct the Escrow Agent to pay any funds remaining in the Escrow Fund (less any amounts then subject to any claim by any Buyer Indemnified Party against the Sellers) to the Sellers.

(e) Subject to paragraphs (a) – (d) above, the Buyer and the Sellers shall promptly instruct the Escrow Agent to pay any amounts that are subject to any claim by any Buyer Indemnified Party against the Sellers to such Buyer Indemnified Party or the Sellers, as appropriate, upon the final determination of such claim.

Section 9.8 Assignment of Claims. If any Buyer Indemnified Party receives any payment from the Sellers in respect of any Losses pursuant to Section 9.2 and the Buyer Indemnified Party had a reasonable and good faith basis for recovering all or a significant portion of such Losses from a third party (and specifically excluding Vornado Realty Trust, Vornado Realty L.P., the Buyer, any Target or Subsidiary, any Affiliate of any of the foregoing, any existing or former owner of an equity interest in any of the foregoing, any lender or servicer or collateral agent in respect of any financing binding upon any Target or Subsidiary or any assets of any of them, and any then-current tenant, in its capacity as a tenant or occupant, at either of the Properties) (a "Potential Contributor"), based on the underlying claim asserted against the Sellers, and the Buyer Indemnified Party elected not to pursue such third party claim, the Buyer Indemnified Party shall assign, on a non-recourse basis and without any representation or warranty, such of its rights to proceed against the Potential Contributor as are available and necessary to permit the Sellers to pursue recovery from the Potential Contributor of the amount

of such payment. If any such assignment would afford the Potential Contributor any defense to the payment of the same, such assignment shall not take place and the Buyer Indemnified Party will, at the Sellers' direction and at the Sellers' sole expense, take such reasonable actions as may be requested by the Sellers to seek to recover such claim from such Potential Contributor. Any payment received in respect of such claim against the Potential Contributor (whether by the Sellers or the relevant Buyer Indemnified Party as provided in the immediately preceding sentence) shall be distributed, (i) first, to the Buyer Indemnified Party in the amount of any deductible or similar amount required to be paid or borne by the Buyer Indemnified Party prior to the Sellers being required to make any payment to the Buyer Indemnified Party plus, in the case of any claim by a Buyer Indemnified Party as provided in the immediately preceding sentence, the costs and expenses incurred in investigating, prosecuting, defending or otherwise addressing such claim, (ii) second, to the Sellers in an amount equal to the aggregate payments made by the Sellers to the Buyer Indemnified Party in respect of such claim, plus the costs and expenses incurred in investigating, prosecuting, defending or otherwise addressing such claim and (iii) the balance, if any, to the Buyer Indemnified Party.

Section 9.9 Interest. Any amounts payable to any Buyer Indemnified Party (pursuant to Section 9.2) or any Seller Indemnified Party (pursuant to Section 9.3) shall become immediately due and payable upon the final determination of such claim, and any amounts payable to the Sellers (pursuant to Section 9.7) shall be become immediately due and payable as set forth in Section 9.7. If the Buyer or the Sellers do not pay, or do not instruct the Escrow Agent to pay, such amounts within 30 days of their becoming due and payable pursuant to the preceding sentence, such amounts shall bear interest at a rate equal to the rate of interest from time to time published in The Wall Street Journal as the prime rate, calculated on the basis of a year of 365 days and the number of days elapsed.

Section 9.10 Exclusivity. Except as specifically set forth in this Agreement, the Ancillary Agreements and any other agreement or instrument being entered into by the Buyer, the Sellers or any Target or Subsidiary concurrently herewith, effective as of the Closing, in the absence of bad faith, willful misconduct or fraud by the other party (to the extent determined in accordance with Section 11.10), the Buyer, on behalf of itself and the other Buyer Indemnified Parties, on the one hand, and the Sellers, on behalf of themselves and the other Seller Indemnified Parties, on the other hand, waive any rights and claims they may have against each other, whether in law or equity, relating to the Targets or the Subsidiaries and/or the transactions contemplated by this Agreement or the Ancillary Agreements. The righ ts and claims waived include, without limitation, claims for contribution or other rights of recovery arising out of or relating to any claims for breach of contract, breach of representation or warranty, negligent misrepresentation and all other claims for breach of duty not amounting to bad faith, willful misconduct or fraud. After the Closing, subject to the foregoing and except for payments owing by any party in the nature of adjustments to the Purchase Price or pursuant to Article VI or Section 2.8, this Article IX will provide the exclusive remedy available to the parties against each other for any breach of any representation, warranty, covenant or other claim arising out of or relating to this Agreement or any Ancillary Agreement and/or the transactions contemplated hereby or thereby.

(a) This Agreement may be terminated by either the Sellers or the Buyer if the Closing has not occurred by the close of business on the Closing Date (as the same may have been adjourned as provided in Section 2.3), and a failure of the party seeking to terminate to fulfill any obligation under this Agreement was not the cause of the failure of the Closing to occur on such date.

(b) This Agreement may be terminated by the Buyer pursuant to the exercise of its right under clause (2) of the proviso contained in Section 5.16(b) of this Agreement.

Section 10.2 Effect of Termination. In the event of termination of this Agreement as provided herein, this Agreement shall forthwith become void and there shall be no liability on the part of either party except (a) for the provisions of Sections 3.18 and 4.5 relating to broker's fees and finder's fees, Section 5.7 relating to confidentiality, Section 5.9 relating to public announcements, Sections 10.3 and 10.4 relating to payments from the Escrow Fund, Section 11.1 relating to fees and expenses, Section 11.5 relating to notices, Section 11.8 relating to third-party beneficiaries, Section 11.9 relating to governing law, Section 11.10 relating to dispute settlement and this Section 10.2 and (b) that nothing herein shall relieve either party from liability for any breach of this Agreement or any agreement made as of the date hereof or subsequent thereto pursuant to this Agreement.

Section 10.3 Termination Fee. If, on the Closing Date, the Sellers are ready, willing and capable of closing (it being understood that so long as the Sellers are ready, willing and capable of implementing any of the agreements, obligations or covenants set forth in Sections 5.2 and 5.3 of this Agreement and satisfying the other conditions precedent to the obligations of the Buyer set forth in clauses (a), (b) and (f) of Section 8.3 of this Agreement immediately prior to the Closing, they shall not be required to actually implement those transactions in order to satisfy the foregoing standard) and the Buyer is required by the terms hereof, but defaults in its obligation, to effectuate the Closing, then the Sellers shall be entitled to receive from the Buyer as liquidated damages for the damages suffered by the Sellers, an amount equal to $100,000,000 (which amount the parties agree is a reasonable estimate of the actual damages that will be suffered by the Sellers and does not constitute a penalty), and the Buyer and the Sellers shall instruct the Escrow Agent to pay the that amount out of the Escrow Fund to the Sellers. The termination fee described in this Section 10.3 will be the sole and exclusive remedy that the Sellers will have for any Buyer breach constituting or resulting in a failure of the Buyer to purchase the Shares and the Partnership Intercompany Notes as provided herein.

Section 10.4 Return of Escrow Fund. In the event of any termination of this Agreement by the Buyer or the Sellers prior to the Closing for any reason, the Buyer and the Sellers shall instruct the Escrow Agent to pay the amounts remaining in the Escrow Fund (after the payment, if any, of amounts due the Sellers pursuant to Section 10.3), to the Buyer.

Section 11.1 Fees and Expenses. Except as otherwise provided herein, all expenses incurred in connection with this Agreement and the Ancillary Agreements and the transactions contemplated hereby and thereby shall be paid by the party incurring such expenses, whether or not such transactions are consummated. In the event of termination of this Agreement, the obligation of each party to pay its own expenses will be subject to any rights of such party arising from a breach of this Agreement by the other.

Section 11.2 Amendment and Modification. This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing signed on behalf of each party and otherwise as expressly set forth herein.

Section 11.3 Waiver. No failure or delay of either party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder. Any agreement on the part of either party to any such waiver shall be valid only if set forth in a written instrument executed and delivered by a duly authorized officer on behalf of such party.

Section 11.4 Seller Representative. Each of the Sellers, irrevocably and unconditionally appoints Mr. Michael Pei as the representative of all of the Sellers and agrees, for the benefit of that representative and the Buyer, that Mr. Michael Pei alone will represent and act on behalf of all of the Sellers for all purposes under this Agreement, including the giving and/or receiving of any notice or consent or approval contemplated hereunder. In the event of the incapacity or death of Mr. Michael Pei, the Sellers shall nominate a new representative within five Business Days, and will provide notice of such nomination to the Buyer as set forth herein, and absent such appointment the Sellers agree that Mr. Henry Cheng will serve as the sole representative of the Sellers in the capacity described above until such time as they have appointed another representative to replace Mr. Pei in the capacity described above and have advised the Buyer of that appointment in writing.

null and void; provided, however, that the Buyer may assign this Agreement to any Affiliate of the Buyer immediately prior to, but conditioned upon, the Closing, provided, however, that: (i) such assignment shall not shall eliminate or release any of the Buyer's obligations pursuant to this Agreement or the Ancillary Agreements, and (ii) the Buyer and any such Affiliate shall execute and deliver to the Sellers an assignment and assumption agreement in a form reasonably acceptable to the Sellers wherein such Affiliate unconditionally assumes all of the Buyer's rights and obligations under this Agreement and the Ancillary Agreements.

Section 11.16 Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application of such provision to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application of such provision, in any other jurisdiction.
