SL GREEN AGREES TO ACQUIRE

ONE MADISON AVENUE

FROM METLIFE

CREDIT SUISSE FIRST BOSTON PROVIDES FINANCING

New York, NY – March 30, 2005 – SL Green Realty Corp. (NYSE: SLG) announced today that it has entered into an agreement to acquire the fee interest in One Madison Avenue from Metropolitan Life Insurance Company (MetLife) for $918 million. One Madison Avenue consists of two contiguous buildings - the South Building and the North Tower - totaling approximately 1.4 million square feet. The transaction is scheduled to close in approximately 30 days.

Originally constructed by MetLife as its headquarters, One Madison Avenue is one of Manhattan’s earliest skyscrapers and has had only one owner since its inception. The building is situated on approximately 1.93 acres overlooking Madison Square Park, occupying an entire city block between Madison Avenue and Park Avenue South between 23^rd and 24^th Streets. It is one of the few high quality office buildings in New York City with direct park frontage and is considered the visual centerpiece of Midtown South. One Madison Avenue is principally leased to Credit Suisse First Boston (USA), Inc. (CSFB) which occupies the facility as part of its headquarters campus.

The acquisition continues SL Green’s strategy of capitalizing on corporate divestitures of real

1

estate, most recently highlighted by the Company’s acquisition of properties sold by the McGraw-Hill Companies (1221 Avenue of the Americas) and TIAA-CREF (485 Lexington Avenue and 750 Third Avenue).

Commenting on the acquisition, Andrew Mathias, Chief Investment Officer of SL Green, noted that the acquisition provides three distinct opportunities for value creation to shareholders:

(1)          The South Building consists of approximately 1.2 million square feet, and offers floor plates of approximately 91,000 square feet - which are ideal for large corporate users and a unique product in Midtown Manhattan. The building is 95.5% net leased to CSFB through 2020. The high credit quality of CSFB underpins the investment with a 15-year securitizable revenue stream.

(2)          The North Tower, which was completed in 1909 and is a Landmark property, contains 41 stories consisting of 267,000 square feet and is zoned for residential and office use. SL Green and CSFB currently intend to physically separate the South Building and the North Tower and convert the North Tower to residential condominium units. The property offers spectacular views throughout the building, which are protected by Madison Square Park. This coupled with small floor plates and high ceilings makes the building an ideal candidate for residential use. Mr. Mathias noted, “The Company has participated in a number of residential conversions through its structured finance portfolio and through investment in its commercial real estate specialty finance REIT affiliate, Gramercy Capital Corp. We consider this to be one of the most unique conversion opportunities in Manhattan.”

(3)          Air rights associated with the property could provide for the development of approximately 470,000 square feet of additional space. This would enable the Company to take advantage of a substantial additional development opportunity in the Flatiron District, which we believe has become one of the most fashionable neighborhoods in Manhattan. The Flatiron District offers a wealth of amenities, superior transportation convenience, and premier cultural and recreational venues.

The Company stated that CSFB’s tenancy and capital commitments provided a competitive advantage with respect to enhanced financeability of the office lease, unlocking of the residential value, and allowing for a significant development opportunity if underlying air rights are ultimately utilized. Additionally, given its intimate knowledge of the properties and its leases, CSFB was able to provide the most attractive and flexible financing in what was a highly sought after debt assignment. SL Green will use up to $805 million of financing to fund the acquisition and development of the project, of which the Company has obtained $690 million of 15-year fixed rate financing.

SL Green will initially own 100% of the office component of the project but intends to bring in a partner for up to a 50% interest consistent with previous joint venture arrangements. SL Green and CSFB will share in the profits of the residential component.

Marc Holliday, President and Chief Executive Officer of SL Green, stated, “We are thrilled that

2

MetLife had the confidence to select SL Green as the new steward of One Madison, an asset that the firm has owned for nearly 100 years, and is a significant part of MetLife’s storied history. We also are extremely happy with this acquisition that provides a steady stream of earnings for years to come from this trophy asset, along with substantial upside in conversion and development opportunities. By identifying the most cost efficient capital and tailoring the appropriate ownership structure, we believe we have again upgraded the quality of our portfolio and positioned ourselves for solid future earnings growth.”

Darcy Stacom, William Shanahan, and Paul Leibowitz of CB Richard Ellis acted as exclusive agents for MetLife on the sale of One Madison Avenue.

Escrow Agent shall execute this Agreement solely for the purpose of being bound by the provisions of Sections 1.5 and 1.6 hereof.

ARTICLE  II

TITLE AND SURVEY

Section 2.1                                   Title Inspection Period.  Purchaser acknowledges and agrees that (a) Seller has furnished to Purchaser prior to the Effective Date: (i) a current preliminary title report dated December 18, 2004 (the “Title Commitment”), issued by Chicago Title Insurance Company on the Real Property, accompanied by copies of all documents referred to in the report; (ii) a copy of the land title survey (“the “Survey”) prepared by Link Land Surveyors, P.C. dated March 9, 2005, and (iii) copies of the most recent property tax bills for the Property; (b) Purchaser has had an opportunity, prior to the Effective Date, to order its own title report and survey for the Physical Property; and (c) any and all matters (the “Existing Title, Tax and Survey Matters”) referred to, reflected in or disclosed by, the materials referred to in the preceding sub-paragraphs (a) (i) through (iii), inclusive, have been agreed to and accepted by Purchaser (including but not limited to, any and all exceptions of title set forth in Schedule B of the Title Commitment) and that, as of the Effective Date, Purchaser has approved the Existing Title, Tax and Survey Matters and the condition of title to the Real Property.

Section 2.2                                   Pre-Closing “Gap” Title Defects.   Purchaser may, after the Effective Date but prior to the Closing, notify Seller in writing  (the “Gap Notice”) of any objections to title (a) raised by the Title Company (as defined in Section 2.5 hereof) between the Effective Date and the Closing and (b) not disclosed by the Title Company or otherwise disclosed in writing to Purchaser prior to the Effective Date; provided that Purchaser must notify Seller of such objection to title within two (2) business days of being made aware of the existence of such exception.  If Purchaser issues a Gap Notice to Seller, Seller shall have five (5) business days after receipt of the Gap Notice to notify Purchaser (a) that Seller will remove such objectionable exceptions from title on or before the Closing; provided that Seller may extend the Closing for such period as shall be required to effect such cure, but not beyond thirty (30) days; or (b) that Seller elects not to cause such exceptions to be removed.  The procurement by Seller of a commitment for the issuance of the Title Policy (as defined in Section 2.5 hereof) or an endorsement thereto (in form and substance reasonably acceptable to Purchaser) insuring Purchaser against any title exception which was disapproved pursuant to this Section 2.2 shall be deemed a cure by Seller of such disapproval.  If Seller gives Purchaser notice under clause (b) above, Purchaser shall have five (5) business days in which to notify Seller that Purchaser will nevertheless proceed with the purchase and take title to the Property subject to such exceptions, or that Purchaser will terminate this Agreement.  If this Agreement is terminated pursuant to the foregoing provisions of this paragraph, then neither party shall have any further rights or obligations hereunder (except for any indemnity obligations of either party pursuant to the other provisions of this Agreement), the Deposit shall be returned to Purchaser and each party shall bear its own costs incurred hereunder.  If Purchaser shall fail to notify Seller of its election within said five-day period, Purchaser shall be deemed to have elected to proceed with the purchase and take title to the Property subject to such exceptions.

(j)                                     the occupancy of the South Building pursuant to a temporary certificate of occupancy, as the tenant under the Net Lease (the “Tenant”) is obligated to obtain a permanent certificate of occupancy for such building;

(k)                                  all matters which would be revealed or disclosed by a physical inspection of the Physical Property on the Effective Date;

(l)                                     the license agreement between Seller and Tenant pursuant to which the Wyeth Paintings shall remain in the Building after the Closing.

5

from the Physical Property and Purchaser shall cooperate with Seller in connection with any such removal).  The rights of Seller under this subdivision (l), including the right to remove the Wyeth Paintings with the cooperation of Purchaser, shall survive the Closing and the transfer of the Property to Purchaser; and

(m)                               Seller has claimed federal rehabilitation tax credits for the Tower for a rehabilitation project that ended on March 31, 2003, and all of such credits are personal to Seller and are not being transferred to Purchaser.

Evidence of delivery of title in accordance with the terms of this Section 2.5 shall be the issuance by Chicago Title Insurance Company, or another national title company (the “Title Company”), of a 1992 ALTA Owner’s Policy of Title Insurance (the “Title Policy”) covering the Real Property, in the full amount of the Purchase Price, subject only to the Permitted Exceptions.

At Seller’s option, and for convenience, Seller may omit from the Deed the recital of any or all of the “subject to” clauses herein contained and/or any other title exceptions, defects or objections which have been waived by Purchaser in accordance with the terms of this Agreement, or consented to in writing by Purchaser, but the same shall nevertheless survive delivery of the Deed. The terms of the immediately preceding sentence shall survive the Closing;

(b)                                 deliver to Purchaser a duly executed bill of sale (the “Bill of Sale”) conveying the Personal Property, if any, without warranty of title or use and without warranty, express or implied, as to merchantability and fitness for any purpose and in the form attached hereto as Exhibit F;

(f)                                    In the event that any representation or warranty of Seller made herein needs to be modified due to changes since the Effective Date, deliver to Purchaser a certificate, dated as of the date of Closing and executed on behalf of Seller by a duly authorized officer thereof, identifying any representation or warranty which is not, or no longer is, true and correct and explaining the state of facts giving rise to the change.  In no event shall Seller be liable to Purchaser for, or be deemed to be in default hereunder by reason of, any breach of representation or warranty which results from any change that (i) occurs between the Effective Date and the date of Closing and is expressly permitted under the terms of this Agreement,  or (ii) occurs between the Effective Date and the date of the Closing and is beyond the reasonable control of Seller to prevent; provided, however, that the occurrence of a change which is not permitted hereunder or is beyond the reasonable control of Seller to prevent shall, if materially adverse to Purchaser, constitute the non-fulfillment of the condition set forth in Section 4.6(b) hereof; if, despite changes or other matters described in such certificate, the Closing occurs, Seller’s representations and warranties set forth in this Agreement shall be deemed to have been modified by all statements made in such certificate;

(b)                                 join Seller in execution of the Assignment of Leases, Assignment of Contracts, Tenant Notices and NYC Notice;

(c)                                  In the event that any representation or warranty of Purchaser set forth in herein needs to be modified due to changes since the Effective Date, deliver to Seller a certificate, dated as of the date of Closing and executed on behalf of Purchaser by a duly authorized representative thereof, identifying any such representation or warranty which is not, or no longer is, true and correct and explaining the state of facts giving rise to the change.  In no event shall Purchaser be liable to Seller for, or be deemed to be in default hereunder by reason of, any breach of representation or warranty set forth in Sections 5.6 (a) or (b) hereof which results from any change that (i) occurs between the Effective Date and the date of Closing and is expressly permitted under the terms of this Agreement,  or (ii) occurs between the Effective Date and the date of the Closing and is beyond the reasonable control of Purchaser to prevent; provided, however, that the occurrence of a change which is not permitted hereunder or is beyond the reasonable control of Purchaser to prevent shall, if materially adverse to Seller, constitute the non-fulfillment of the condition set forth in Section 4.7(c) hereof provided nothing contained in this Section shall be deemed to waive any remedies Seller may have for a default by Purchaser; if, despite changes or other matters described in such certificate, the Closing occurs, Purchaser’s representations and warranties set forth in this Agreement shall be deemed to have been modified by all statements made in such certificate;

Section 4.4                                   Credits and Prorations.

(a)                                  All income and expenses of the Property shall be apportioned as of 12:01 a.m., on the day of Closing, as if Purchaser were vested with title to the Property during the entire day upon which Closing occurs.  Subject to the provisions of this Section 4.4, such prorated items shall include without limitation the following:  (i) all Rents, if any; (ii) taxes and assessments (including personal property taxes on the Personal Property) levied against the Property to the extent such taxes and assessments are not the obligation of the Tenant under the Net Lease to pay; (iii) utility charges for which Seller is liable (to the extent such utility charges are not the obligation of the Tenant under the Net Lease to pay), if any, such charges to be apportioned at Closing on the basis of the most recent meter reading occurring prior to Closing (dated not more than fifteen (15) days prior to Closing) or, if unmetered, on the basis of a current bill for each such utility; (iv) all amounts payable under brokerage agreements and Operating Agreements, pursuant to the terms of this Agreement; (v) all amounts payable by the landlord under articles 34(f), 35 and 37 of the Net Lease and (vi) any other operating expenses or other items pertaining to the Property (to the extent the same are not the obligation of the tenant under the Net Lease to pay) which are customarily prorated between a purchaser and a seller in the county in which the Property is located.

(b)                                 Notwithstanding anything contained in Section 4.4(a) hereof:

(i)                                     At Closing, (A) Seller shall, at Seller’s option, either deliver to Purchaser any Security Deposits actually held by Seller pursuant to the Leases or credit to the account of Purchaser the amount of such Security Deposits (to the extent such Security Deposits have not been applied against delinquent Rents or otherwise as provided in the Leases), and (B) Purchaser shall credit to the account of Seller all refundable cash or other deposits posted by Seller with utility companies serving the Property, or, at Seller’s option, Seller shall be entitled to receive and retain such refundable cash and deposits;

(ii)                                  Any taxes paid by Seller at or prior to Closing shall be prorated based upon the amounts actually paid.  If taxes and assessments due and payable by Seller during the year of Closing have not been paid before Closing, Seller shall be charged at Closing an amount equal to that portion of such taxes and assessments which relates to the period before Closing and Purchaser shall pay the taxes and assessments prior to their becoming delinquent.  Any such apportionment made with respect to a tax year for which the tax rate or assessed valuation, or both, have not yet been fixed shall be based upon the tax rate and/or assessed valuation last fixed.  To the

11

extent that the actual taxes and assessments for the current year differ from the amount apportioned at Closing, the parties shall make all necessary adjustments by appropriate payments between themselves within thirty (30) days after such amounts are determined following Closing, subject to the provisions of Section 4.4(d) hereof;

(iii)                               Charges referred to in Section 4.4(a) hereof which are payable by any tenant to a third party shall not be apportioned hereunder, and Purchaser shall accept title subject to any of such charges unpaid and Purchaser shall look solely to the tenant responsible therefor for the payment of the same.  If Seller shall have paid any of such charges on behalf of any tenant, and shall not have been reimbursed therefor by the time of Closing, Purchaser shall credit to Seller an amount equal to all such charges so paid by Seller;

(iv)                              As to utility charges referred to in Section 4.4(a)(iii) hereof, Seller may on notice to Purchaser elect to pay one or more or all of said items accrued to the date hereinabove fixed for apportionment directly to the person or entity entitled thereto, and to the extent Seller so elects, such item shall not be apportioned hereunder, and Seller’s obligation to pay such item directly in such case shall survive the Closing or any termination of this Agreement;

(v)                                 Seller shall be responsible for the payment of all tenant improvement costs and leasing commissions with respect to the Net Lease, if any, that arose in the period prior to the Effective Date.   Purchaser shall be responsible for the payment of all other Tenant Inducement Costs and leasing commissions (including the override commissions earned by Cushman & Wakefield pursuant to its exclusive agency agreement with Seller) with respect to the relocation of Guy Carpenter & Company from the Tower, the prospective New York Academy of Sciences (“NYAS”) lease, and any other new leases.  Notwithstanding the foregoing, Seller shall reimburse Purchaser for the Excess Costs (as defined below) with respect to not more than 50,000 rentable square feet in the South Building, but only to the extent that Purchaser’s Tenant Inducement Costs and leasing commissions for such 50,000 rentable square feet exceed $3,000,000 (such excess hereinafter referred to as the “Excess Costs”), provided that in no event shall such reimbursement exceed  $1,500,000.  For purposes hereof, the term “Tenant Inducement Costs” shall mean any out-of-pocket payments required under a Lease to be paid by the landlord thereunder not later than 12 months after the Closing to or for the benefit of the tenant thereunder which is in the nature of a tenant inducement, including specifically, without limitation, tenant improvement costs, base building costs, lease buyout or relocation costs, and moving, design, refurbishment and club membership allowances.  The term “Tenant Inducement Costs” shall not include loss of income resulting from any free rental period, it being agreed that Seller shall bear the loss resulting from any free rental period until the date of Closing and that Purchaser shall bear such loss from and after the date of Closing.  In order to receive reimbursement of Excess Costs, Purchaser shall deliver evidence reasonably satisfactory to Seller that Purchaser has incurred the Excess Costs, and Seller shall promptly thereafter reimburse Purchaser therefor.

(vi)                              Unpaid and delinquent Rent collected by Seller and Purchaser after the date of Closing shall be delivered as follows: (a) if Seller collects any unpaid or delinquent Rent for the Property, Seller shall, within fifteen (15) days after the receipt thereof, deliver to Purchaser any such Rent which Purchaser is entitled to hereunder relating to the date of Closing and any period thereafter, and (b) if Purchaser collects any unpaid or delinquent Rent from the Property, Purchaser shall, within fifteen (15) days after the receipt thereof, deliver to Seller any such Rent

12

which Seller is entitled to hereunder relating to the period prior to the date of Closing. Purchaser will make a good faith effort after Closing to collect all Rents in the usual course of Purchaser’s operation of the Property.  Seller and Purchaser agree that all Rent received by Seller or Purchaser after the date of Closing shall be applied first to current Rent and then to delinquent Rent, if any, in the inverse order of maturity. Purchaser will make a good faith effort after Closing to collect all Rents in the usual course of Purchaser’s operation of the Property, but Purchaser will not be obligated to institute any lawsuit or other collection procedures to collect delinquent Rents.  Seller may attempt to collect any delinquent Rents owed Seller and may institute any lawsuit or collection procedures, but may not evict any tenant after Closing.  In the event that there shall be any Rents or other charges under any Leases which, although relating to a period prior to Closing, do not become due and payable until after Closing or are paid prior to Closing but are subject to adjustment after Closing (such as year end common area expense reimbursements and the like), then any Rents or charges of such type received by Purchaser or its agents or Seller or its agents subsequent to Closing shall, to the extent applicable to a period extending through the Closing, be prorated between Seller and Purchaser as of Closing and Seller’s portion thereof shall be remitted promptly to Seller by Purchaser.

(vii)                           At such time as the NYCDOT consents to the assignment of Seller’s interest in the Revocable Consents, Purchaser shall promptly following receipt of such consent, pay to Seller the amount of the security fund deposited under each of the Revocable Consents and Seller shall assign to Purchaser all of Seller’s right, title and interest in and to such funds deposited.

(c)                                  Seller may prosecute appeals (if any) of the real property tax assessment for the period prior to the Closing, and may take related action which Seller deems appropriate in connection therewith.  Purchaser shall cooperate with and perform such ministerial and non-ministerial acts, and execute any and all documents reasonably requested by Seller, in connection with such appeal and collection of a refund of real property taxes paid.  Seller owns and holds all right, title and interest in and to such appeal and refund, and all amounts payable in connection therewith shall be paid directly to Seller by the applicable authorities.  If such refund or any part thereof is received by Purchaser, Purchaser shall promptly pay such amount to Seller.  Any refund received by Seller shall be distributed as follows:  first, to reimburse Seller for all costs incurred in connection with the appeal; second, with respect to refunds payable to tenants of the Real Property pursuant to the Leases, to such tenants in accordance with the terms of such Leases; and third, to Seller to the extent such appeal covers the period prior to the Closing, and to Purchaser to the extent such appeal covers the period as of the Closing and thereafter.  If and to the extent any such appeal covers the period after the Closing, Purchaser shall have the right to participate in such appeal.

(d)                                 Except as otherwise provided herein, any revenue or expense amount which cannot be ascertained with certainty as of Closing shall be prorated on the basis of the parties’ reasonable estimates of such amount, and shall be the subject of a final proration one hundred eighty (180) days after Closing, or as soon thereafter as the precise amounts can be ascertained.  Any reconciliation of revenue or expense amounts relating to Leases (other than the Net Lease) which needs to be made in connection with this Section 4.4 shall be prepared by Purchaser and submitted to Seller for Seller’s review and approval. Purchaser shall promptly notify Seller when it becomes aware that any such estimated amount has been ascertained. Once all revenue and expense amounts have been ascertained, Purchaser shall prepare, and certify as correct, a final proration

13

statement which shall be in a form consistent with the closing statement delivered at Closing and which shall be subject to Seller’s approval.  Upon Seller’s acceptance and approval of any final proration statement submitted by Purchaser, such statement shall be conclusively deemed to be accurate and final, and any payment due to any party as a result of such final proration shall be made within thirty (30) days of such approval by Seller.

(e)                                  With respect to the Net Lease, Tenant bills Seller monthly for estimated “Operating Payments” (as such term is defined in the Net Lease), with a reconciliation of amounts billed and actual amounts incurred made within 120 days after the end of each calendar year.  The estimated Operating Payment for the month in which the Closing occurs shall be pro-rated between Seller and Purchaser on the basis of each party’s period of ownership during such calendar month.  Upon the reconciliation by Tenant of the amounts billed for Operating Payments and the amounts actually incurred for Operating Payments for the calendar year 2005, Seller and Purchaser shall be liable for underpayments of Operating Payments (“Underpayments”), and shall be entitled to reimbursements for overpayments of Operating Payments (“Overpayments”), as the case may be, on a pro-rata basis based upon each party’s period of ownership during such calendar year.  Purchaser shall promptly remit to Seller Seller’s pro-rata share of Overpayments received by Purchaser from Tenant.  Seller shall promptly remit to Purchaser Seller’s pro-rata share of Underpayments.  Seller hereby reserves the right to exercise its right to dispute the correctness of the Operating Statement given by Tenant for the calendar year 2005 pursuant to the provisions of Section 35.6 of the Net Lease with respect to Seller’s period of ownership.

(f)                                    Subject to the final sentence of Section 4.4(d) hereof, the provisions of this Section 4.4 shall survive Closing.

Section 4.5                                   Transaction Taxes and Closing Costs.

(a)                                  Seller and Purchaser shall execute such returns, questionnaires and other documents as shall be required with regard to all applicable real property transaction taxes imposed by applicable federal, state or local law or ordinance;

(b)                                 Seller shall pay the fees of any counsel representing Seller in connection with this transaction.  Seller shall also pay the following costs and expenses:

(i) one-half of the escrow fee, if any, which may be charged by the Escrow Agent or Title Company;

(ii) the fees for Seller’s Broker; and

(iii) any transfer tax, sales tax, documentary stamp tax or similar tax which becomes payable by reason of the transfer of the Property from Seller to Purchaser;

14

(c)                                  Purchaser shall pay the fees of any counsel representing Purchaser in connection with this transaction.  Purchaser shall also pay the following costs and expenses:

(i) one-half of the escrow fee, if any, which may be charged by the Escrow Agent or Title Company;

(ii) the fee for the title examination and the Title Commitment and the premium for the Owner’s Policy of Title Insurance to be issued to Purchaser by the Title Company at Closing, and all endorsements thereto;

(iii) the cost of the Survey;

(iv) the fees for recording the Deed; and

(v) the fees for any broker, other than Seller’s Broker, that Purchaser has dealt with or engaged on its behalf or for its benefit, in connection with the transaction contemplated by this Agreement, if any;

(d)                                 The Personal Property is included in this sale without charge and each party acknowledges that no portion of the Purchase Price is attributable to the Personal Property;

(e)                                  All costs and expenses incident to this transaction and the closing thereof, and not specifically described above, shall be paid by the party incurring same; and

(f)                                    The provisions of this Section 4.5 shall survive the Closing.

Section 4.6                                   Conditions Precedent to Obligations of Purchaser.  The obligation of Purchaser to consummate the transaction hereunder shall be subject to the fulfillment on or before the date of Closing of all of the following conditions, any or all of which may be waived by Purchaser in its sole discretion:

(b)                                 All of the representations and warranties of Seller contained in this Agreement shall be true and correct in all material respects as of the date of Closing (with appropriate modifications permitted under this Agreement);

(c)                                  The members of the Board of Directors of the Condominium and the Officers of the Condominium shall deliver written notices resigning their respective positions of the Condominium effective the date of the Closing (collectively, the “Board Resignation Letters”); and

(d)                                 Seller shall have performed and observed, in all material respects, all covenants and agreements of this Agreement to be performed and observed by Seller as of the date of Closing.

Section 4.7                                   Conditions Precedent to Obligations of Seller.  The obligation of Seller to consummate the transaction hereunder shall be subject to the fulfillment on or before the

(b)                                 From and after the Effective Date hereof until the Closing or earlier termination of this Agreement, neither Seller nor Purchaser will enter into any amendment, renewal or expansion of an existing Lease or any new Lease without the consent of the other party.

18

pre-condition to Closing that the AG Approval shall have been obtained and in no event shall the Closing be postponed or delayed by the failure of Purchaser to have obtained the AG Approval.

Section 5.6                                   Representations and Warranties of Purchaser.  Purchaser hereby makes the following representations and warranties to Seller as of the Effective Date, which representations and warranties shall be deemed to have been made again as of the Closing, subject to Section 4.3(c) hereof:

A Transfer pursuant to an option or similar contract described in item (A)(i)(c) above shall be deemed to have occurred upon the exercise of the applicable option, the delivery (if applicable) of a deed, assignment or other evidence of such Transfer to the transferee or its agent or designee and payment of consideration therefor.

(iii)                               “Net Gain” with respect to any asset or interest subject to a Transfer is the excess, as of the date of such Transfer, of (a) the fair market value of the gross consideration (including, without limitation, cash and all other property, notes, securities, contracts, and instruments) given to or for the benefit of Purchaser or any direct or indirect holder of an interest in Purchaser (other than the sale of stock in any publicly held company) or the Property in connection with the Transfer of such asset or interest over (b) the sum of (1) all reasonable Transfer expenses, such as legal fees, brokerage commissions, transfer taxes, recording fees, and other fees for customary transfer services paid to parties unrelated to Purchaser, the transferor, and the transferee in connection with the Transfer of such asset or interest, plus (2) the product of the Cost Percentage indicated below for such asset or interest multiplied by the Purchase Price, plus (3) the unamortized portion of any additional capitalized or expensed investment fully paid by Purchaser (as evidenced to the reasonable satisfaction of Seller) after the Closing Date and prior to the Transfer which is attributable to such asset or interest.

(iv)                              For purposes of this Section 10.22, the “Cost Percentages” for each of the portions of the Property shall be as set forth in the Deeds for the South Building and the Tower, or if separate Deeds are not delivered, shall be based upon values of 802 and 116, respectively (South Building: Tower).  To the extent that, rather than a transfer of the South Building or the Tower, the applicable Transfer relates to an interest in the South Building and/or the Tower, the Cost Percentage will be the applicable percentage based upon the portion of the Property directly or indirectly represented by such interest.  If the entire Property or all of the ownership interests in Purchaser are the subject of a Transfer, the Cost Percentage shall be one hundred percent (100%).  If the interest subject to a Transfer represents less than one hundred percent of the ownership interest in Purchaser, the applicable Cost Percentage for such Transfer shall be equal to the percentage of ownership interest being transferred.

(B)                                The additional consideration payable by Purchaser to Seller under this Section 10.22 shall be due and payable by wire transfer of immediately available funds (to an account designated by Seller) within ten (10) days after the date the Transfer occurs, whether or not the gross consideration given in connection for Transfer is in cash or non-cash form.

31

(C)                                Any dispute arising from or in any way relating to this Section 10.22, including breach thereof, shall be determined in a federal or state court in the City of New York, to which Purchaser and Seller hereby submit for jurisdiction; provided, that by written notice to Purchaser given within twenty (20) days after Seller has been served with a complaint which has been filed in court, Seller may in its sole and absolute discretion cause such dispute to be resolved instead by expedited arbitration in accord with the Commercial Arbitration Rules for Expedited Procedures of the American Arbitration Association by a single arbitrator who is appointed by the President of the Real Estate Board of New York and has no affiliation with any party to such dispute.

(D)                               The provisions of this Section 10.22 shall survive Closing.

Section 10.23.                  Joint and Several Liability.   Each of the entities comprising Purchaser shall be jointly and severally liable for all the obligations of Purchaser under this Agreement.
