(3) Finally, the quotient shall be calculated of (a) the amount calculated in subclause (2) of this subparagraph, divided by (b) the capitalization rate for the market in which such Holdback/Adjustment Property is located, as set forth in the Side Letter Agreement opposite the name of the Company that holds fee simple or leasehold title to such Holdback/Adjustment Property (the "Capitalization Rate"), which quotient shall constitute the Closing Holdback for such Holdback/Adjustment Property. (4) Definitions: "Weighted Base Net Rent" shall mean, with respect to each Holdback/Adjustment Property (as determined individually with respect to each such Property) an amount equal to the quotient of (A) the sum produced by adding the result of the following calculation for each space located within the Improvements on the applicable Holdback/Adjustment Property that is Vacant Space as of the applicable Closing: (i) the projected base net rent per square foot set forth in the Side Letter Agreement for the applicable Vacant Space as of the applicable Closing (the "Projected Base Net Rent"), multiplied by (ii) the square footage of such Vacant Space as set forth in the Side Letter Agreement, divided by (B) the aggregate square footage for all such Vacant Space at the applicable Holdback/Adjustment Property as of the applicable Closing. "Vacant Space" shall mean the space located within the Improvements located on a Holdback/Adjustment Property that is not Leased as of the applicable date upon which such calculation is to be made hereunder for such Holdback/Adjustment Property (i.e., the Effective Date, the date of a Closing, the Determination Date (as herein defined) or such other calculation date as is herein provided). "Leased" shall mean space which is leased to a Qualified Tenant under a Qualified Lease. "Qualified Lease" shall mean any lease of space included in the applicable Property which satisfies each of the following requirements: (a) it has been approved in writing by Purchaser (which approval shall be subject to the 5 standards for determining "reasonable" approval as provided in Paragraph 6.5(b)) and fully executed by the landlord and the tenant; (b) as evidenced by an estoppel certificate in the form attached to this Agreement as Exhibit C or, if the applicable Qualified Lease was dated less than forty-five (45) days prior to the applicable Closing or end of a calendar quarter (for the purpose of making the determination under Paragraph 1.4(b) below), as applicable, an acceptance letter in the form attached to this Agreement as Exhibit C-1, (i) it shall be in full force and effect and in good standing and free from default by any party thereto, (ii) the tenant thereunder shall have accepted in writing, and shall have occupied (if the applicable tenant is a Major Tenant (as herein defined)), the premises subject or to be subject to such lease, and shall have been obligated to pay, and shall have commenced to pay, the rent thereunder, or, if the subject lease provides for a free rent period which is in effect at the time this determination is being made, then the tenant thereunder shall have been obligated to pay, and shall have commenced to pay, expense reimbursements thereunder, (iii) the tenant improvements required to be made or paid for by the landlord in connection therewith shall have been substantially completed (except for so called "punchlist items," i.e., minor details of construction, decoration or mechanical adjustments which do not materially interfere with a tenant's occupancy of the premises and which shall be completed diligently by Seller but in any event prior to any time such work is required to be completed under the applicable lease) and shall have been paid in full by Seller, and (iv) all leasing commissions required to be paid for by the landlord in connection therewith have been paid in full (or, if not paid in full, Purchaser shall have received a credit at the applicable Closing for any commissions payable after the applicable Closing as provided herein); (c) neither Seller nor any related party of Seller (including Newco (as herein defined)) shall be the tenant thereunder; and (d) the tenant thereunder shall not have received any payment or other consideration from Seller or any related party of Seller in connection therewith other than tenant inducements approved in writing by Purchaser.

(2) retained by Purchaser, within fifteen (15) days after the end of each calendar quarter after the Closing as an adjustment to the Purchase Price at the applicable Closing (the "Closing Purchase Price Adjustment"), with respect to any Vacant Space at the applicable Holdback/Adjustment Property that shall have been Leased pursuant to a Qualified Lease during the calendar quarter just ending pursuant to which the Projected Base Net Rent attributable to the applicable Vacant Space is greater than the Actual Base Net Rent payable under the Qualified Lease for such Vacant Space, an amount equal to (A) the actual square footage of each Vacant Space Leased during the applicable calendar quarter (with respect to the applicable Holdback/Adjustment Property), multiplied by the difference between (x) the Projected Base Net Rent for such Vacant Space and (y) the Actual Base Net Rent for such Vacant Space, the product of which shall be divided by (B) the Capitalization Rate for the applicable Holdback/Adjustment Property. (c) Notwithstanding anything contained herein to the contrary, with respect to the NY III Property and the NY IV Property only, if the Actual Base Net Rent is greater than the Projected Base Net Rent attributable to the applicable Vacant Space at the applicable Holdback/Adjustment Property (i) in making the calculations in Paragraph 1.4(b)(1)(i) above, an amount equal to seventy-five percent (75%) of the first $1.00 per square foot (or lesser amount if Actual Base Net Rent exceeds Projected Base Net Rent by less than $1.00 per square foot) of Actual Base Net Rent in excess of the Projected Base Net Rent shall also be divided by the applicable Capitalization Rate and added to the amount to be paid to Seller pursuant to Paragraph 1.4(b)(1)(i) with respect to the applicable Holdback/Adjustment Property, and (ii) in making the calculations in Paragraph 1.4(b)(1)(ii) above, an amount equal to the first $1.00 per square foot (or lesser amount if Actual Base Net Rent exceeds Projected Base Net Rent by less than $1.00 per square foot) of Actual Base Net Rent in excess of the Projected Base Net Rent shall be added to the Projected Base Net Rent before determining the difference between Actual Base Net Rent and Projected Base Net Rent for the purpose of performing the net present value calculation provided in that Paragraph 1.4(b)(1)(ii). 9 (d) Notwithstanding anything contained herein to the contrary, with respect to any Holdback/Adjustment Property that has not reached 95% Occupancy (it being the intent and agreement that no amounts, other than an "Earnout Amount" paid to Seller pursuant to the provisions hereof, shall be paid with respect to any Vacant Space Leased in excess of 95% Occupancy), if any Vacant Space in such Holdback/Adjustment Property shall not have been Leased as of the date that is twelve (12) months after the Closing for such Property (the "Determination Date"), then Seller shall receive an amount equal to the product of (A) fifty percent (50%), multiplied by (B) the amount that would result from the application of the provisions of Paragraph 1.4(a) (1)-(3) to such Holdback/Adjustment Property if the calculation were to be made as of the Determination Date (which amount corresponds to the portion of the Closing Holdback for such Holdback/Adjustment Property to which Seller shall not have earned the right to receive in accordance with the provisions hereof as of the Determination Date), and any remaining Closing Holdback for such Holdback/Adjustment Property shall be retained by Purchaser as a permanent adjustment to the Purchase Price, whereupon (except as otherwise provided in this Paragraph 1.4) there shall be no further adjustments to the Purchase Price or payments to the Seller with respect to the applicable Holdback/Adjustment Property, whether in the form of the Closing Purchase Price Adjustment, or otherwise (and Purchaser shall thereafter be responsible for the payment of all leasing commissions and tenant improvement allowances with respect to such Vacant Space). Notwithstanding the foregoing provisions of this Paragraph 1.4(d), if 95% Occupancy has not been achieved by the Determination Date and Seller and a Qualified Tenant shall have entered into a lease prior to the Determination Date which does not satisfy all of the requirements of a Qualified Lease as of the Determination Date (collectively, "Non-Qualified Leases") and on or before the Determination Date Seller notifies Purchaser in writing that Seller desires to extend the Determination Date to allow additional time for any such Non-Qualified Leases to become Qualified Leases, the Determination Date shall be extended to the date that is fifteen (15) months after the applicable Closing; provided, however, that only leases of Vacant Space that were (i) Qualified Leases as of the original Determination Date and (ii) Non-Qualified Leases as of the original Determination Date and which become Qualified Leases as of the extended Determination Date shall be included as Vacant Space that has been Leased in making the determination of the amounts to be paid to Seller and retained by Purchaser pursuant to this Paragraph 1.4(d), which determination shall be made as of the extended Determination Date. (e) Notwithstanding anything to the contrary contained in this Agreement, in no event shall Seller receive aggregate payments pursuant to this Paragraph 1.4 with respect to a Holdback/Adjustment Property in excess of the Closing Holdback with respect to such Holdback/Adjustment Property (excluding any payments made to Seller by Purchaser as Earnout Amounts, which amounts shall not be subject to the foregoing cap in this sentence). In addition, notwithstanding anything to the contrary contained in this Paragraph 1.4, at the time of each calculation of the amount of the Closing Holdback to which either Seller or Purchaser shall be entitled pursuant to the provisions of this Paragraph 1.4, such calculation shall be made with respect to the applicable Property on 10 an aggregate basis (i.e., as if such calculation was the first such calculation being performed with respect to the applicable Property) and if, as a result of such calculation, Seller has received an overpayment or underpayment as a result of the prior payments, if any, made to Seller from the applicable Closing Holdback, then there shall be an appropriate payment made to Seller from the Closing Holdback or from Seller to the Closing Holdback or Purchaser, as the case may be, in order to adjust such payments so as to correct any such overpayment or underpayment. (f) Notwithstanding anything to the contrary contained in this Agreement, with respect to any Vacant Space in excess of 95% Occupancy that is Leased, Seller and Purchaser shall each pay fifty percent (50%) of the tenant improvement costs attributable to such Vacant Space in excess of 95% Occupancy that is Leased. If, as of the Determination Date (or such earlier date upon which a Holdback/Adjustment Property has achieved 95% Occupancy (or the date of the Closing for such Property if such Closing occurs after 95% Occupancy has been achieved)), there is any Vacant Space at such Holdback/Adjustment Property in excess of 95% Occupancy that is not Leased, then at such date Seller shall pay to Purchaser an amount equal to fifty percent (50%) of the Base Tenant Finish Allowances for such Vacant Space. Purchaser shall pay all of the leasing commissions attributable to the leasing of the Vacant Space in excess of 95% Occupancy. (g) Notwithstanding anything to the contrary contained in this Agreement, if Vacant Space is Leased and the initial term of the Qualified Lease (excluding any portion of such term occurring after the date that the applicable Qualified Lease could be terminated pursuant to a termination option contained in such Qualified Lease) is less than five (5) years, the amount to be paid to Seller with respect to the applicable Qualified Lease either as Purchase Price (pursuant to Paragraph 1.3 if applicable) or pursuant to Paragraph 1.4(b)(1) (if applicable) shall be reduced by an amount equal to (such amount being herein referred to as the "Term Reduction Amount") (i) ten percent (10%) (if the Qualified Lease has an initial term of four (4) years or more but less than five (5) years) and (ii) twenty percent (20%) (if the Qualified Lease has an initial term of three (3) years or more but less than four (4) years) of the amount which otherwise would have been paid to Seller under the foregoing Paragraphs, as applicable, determined on a prorated basis (e.g., if the applicable lease term is 4 1/2 years, the applicable percentage would be 5% and if the applicable lease term is 3 1/2 years, the applicable percentage would be 15%). Notwithstanding the foregoing, to the extent that a Qualified Lease at a Holdback/Adjustment Property has an initial term greater than five (5) years (excluding any portion of such term occurring after the date that the applicable Qualified Lease could be terminated pursuant to a termination option contained in such Qualified Lease), Seller shall have the right to utilize the aggregate "Post 5 Year Rent" (as defined below) remaining from time to time after the application of any such Post 5 Year Rent pursuant to the provisions of this Paragraph 1.4 (g) ("Remaining Post 5 Year Rent") to make up all or a portion of the short fall in term of a Qualified Lease having an initial term under five (5) years (excluding any portion of such term occurring after the date that the applicable Qualified Lease could be terminated pursuant to a termination option contained in such Qualified Lease)(a "Short Fall Lease") that is thereafter executed as 11 follows: Seller can apply any Remaining Post 5 Year Rent to a Qualified Lease having a term under five (5) years (excluding any portion of such term occurring after the date that the applicable Qualified Lease could be terminated pursuant to a termination option contained in such Qualified Lease) by applying such Remaining Post 5 Year Rent to the actual square footage and utilizing the Actual Base Net Rent of the applicable Short Fall Lease to determine the extent of additional term such Short Fall Lease would have had if such applicable Remaining Post 5 Year Rent had been paid under such Short Fall Lease and such additional term shall be added to the actual term of the Short Fall Lease solely for the purpose of making the calculation of the Term Reduction Amount pursuant to this Paragraph 1.4 (g). As used herein "Post 5 Year Rent" shall mean an amount equal to the Projected Base Net Rent for the space demised under such Qualified Lease multiplied by the square footage of such Qualified Lease and by the number of years (or fraction thereof), not to exceed five (5), in the initial term of such Qualified Lease in excess of the first (5) years of such Qualified Lease (excluding any portion of such term occurring after the date that the applicable Qualified Lease could be terminated pursuant to a termination option contained in such Qualified Lease). Notwithstanding the foregoing provisions of this Paragraph 1.4(g), if the applicable Qualified Lease has a termination option which can be exercised by the tenant so as to terminate the applicable Qualified Lease prior to the end of a full five year initial term, then (A) if the Term Reduction Amount for such Qualified Lease is equal to or greater than the applicable termination fee that would be payable by the tenant in connection with the exercise of the applicable termination option, then the amount to be paid to Seller with respect to the applicable Qualified Lease either as Purchase Price (pursuant to Paragraph 1.3 if applicable) or pursuant to Paragraph 1.4(b)(1) shall be reduced by the difference between the applicable Term Reduction Amount and the applicable termination fee and Purchaser shall be entitled to receive the applicable termination fee if the tenant exercises such option (it being agreed that any adjustment to the Purchase Price pursuant to this Paragraph 1.4(g) for the applicable Qualified Lease shall not be affected by the applicable tenant's subsequent failure to exercise such termination option), and (B) if the Term Reduction Amount for such Qualified Lease is less than the applicable termination fee that would be payable by the tenant in connection with the exercise of the applicable termination option, then the amount to be paid to Seller with respect to the applicable Qualified Lease either as Purchase Price (pursuant to Paragraph 1.3 if applicable) or pursuant to Paragraph 1.4(b)(1) shall not be reduced by the Term Reduction Amount and Purchaser shall be entitled to receive the applicable termination fee if the tenant exercises such option (it being agreed that the non-adjustment to the Purchase Price pursuant to this Paragraph 1.4(g) for the applicable Qualified Lease shall not be affected by the applicable tenant's subsequent failure to exercise such termination option). Except as provided in this Paragraph 1.4(g), Purchaser shall be entitled to retain or be paid all termination fees paid by tenants under Leases in effect as of the Effective Date or entered into after the Effective Date (in either case subject to Purchaser acquiring the applicable Property). The amount of any reduction to the Purchase Price pursuant to this Paragraph 1.4(g) shall be retained by Purchaser as an adjustment to the Purchase Price for the applicable Holdback/Adjustment Property. (h) Notwithstanding anything to the contrary contained in this Agreement, if Vacant Space 12 is Leased and the amount of the actual base rent escalations in the applicable Qualified Lease as applied to the Actual Base Net Rental payable over the initial term (excluding any portion of such term attributable to option periods and periods occurring after the date such Qualified Lease could be terminated pursuant to any termination options contained in such Qualified Lease) of the applicable Qualified Lease (but in no event to exceed ten (10) years)("Actual Escalated Base Rent") varies from the amount of the Pro Forma Base Rent Escalations (as defined in the Side Letter Agreement) as applied to the Projected Base Net Rent for the applicable Vacant Space over the same period ("Projected Escalated Base Rent"), then the net present value of the variance in the rent for such Vacant Space over the same period and utilizing a discount rate of 10% shall be determined (the "Escalation NPV") and (i) if the Actual Escalated Base Rent is greater than the Projected Escalated Base Rent, the amount of the Escalation NPV shall be added to the Purchase Price (pursuant to Paragraph 1.3 if applicable) or paid to Seller pursuant to Paragraph 1.4(b)(1) (if applicable) with respect to the applicable Holdback/Adjustment Property, and (ii) if the Actual Escalated Base Rent is less than the Projected Escalated Base Rent, the amount of the Escalation NPV shall be retained by Purchaser as an adjustment to the Purchase Price for the applicable Holdback/Adjustment Property. Notwithstanding the foregoing provisions of this Paragraph 1.4(h), (A) if the actual base rent escalations in the applicable Qualified Lease are 3% or less per year, then there shall be no payment to Seller under this Paragraph 1.4(h) with respect to such Qualified Lease regardless of whether the Actual Escalated Base Rent is greater than the Projected Escalated Base Rent, and (B) if the actual base rent escalations in the applicable Qualified Lease are greater than 3% per year and the Actual Escalated Base Rent is greater than the Projected Escalated Base Rent, then the amount to be paid to Seller, if any, under this Paragraph 1.4(h) shall be calculated as if the actual base rent escalations were equal to the applicable Pro Forma Base Rent Escalations plus the amount of the actual base rent escalations above 3% per year. (i) Examples of the application of this Paragraph 1.4 are as set forth in the Side Letter Agreement. 1.5 Purchaser, on or before 9:00 A.M. (San Francisco, California time), October 7, 2003, shall deposit with the San Francisco, California office of the Title Company, as escrow agent, the amount of Eight Million Five Hundred Thousand and No/100 Dollars ($8,500,000), which amount, together with all interest earned thereon, shall be referred to, collectively, as the "Earnest Money." The Earnest Money shall be in the form of a wire transfer of immediately available funds of the United States of America. If Purchaser shall not have so deposited the Earnest Money on a timely basis, as herein required, Seller may terminate this Agreement by written notice thereof to Purchaser, whereupon no party shall have any further obligations to the other hereunder, except as otherwise herein provided. The Earnest Money shall become nonrefundable as of 9:00 A.M. (Pacific Time), October 7, 2003, except as otherwise herein provided. The Earnest Money shall be held and disbursed by the Title Company, pursuant to an earnest money escrow agreement substantially in the form attached hereto as Exhibit D. The Earnest Money shall be invested in a federally issued or insured interest bearing instrument and shall be paid to the party to which the Earnest Money shall be paid, pursuant to the provisions hereof. If the transaction contemplated hereby shall be consummated in accordance with the terms hereof, at each Closing, the Earnest Money allocated to the applicable Properties being acquired 13 at such Closing (the "Earnest Money Allocations") shall be applied to the allocable Purchase Price for such Properties at the applicable Closing. Notwithstanding anything to the contrary contained in this Agreement, if a Closing fails to occur for any reason whatsoever other than Purchaser's default, the Earnest Money allocable to the Properties for which such Closing(s) do not occur shall be returned to Purchaser. ARTICLE 2 REVIEW OF INFORMATION 2.1 On or before the Effective Date, Seller has delivered or made available to Purchaser complete copies of any of the materials listed on Exhibit E attached hereto that shall be in the possession of Seller (the "Due Diligence Materials"). 2.2 From and after the Effective Date and during the term of this Agreement, Seller also shall provide Purchaser and its employees, agents, representatives, attorneys and consultants ("Purchaser's Consultants") access to the Properties, at any reasonable time, during normal business hours, upon reasonable prior notice, to conduct such inspections, investigations, tests, studies, reports, analyses, appraisals, verifications and evaluations with respect to the Interests, Aero SeaTac and/or the Properties, as Purchaser shall deem necessary in its commercially reasonable discretion, subject to the remaining provisions hereof (collectively, the "Investigations"); provided, however, that Purchaser shall not perform any intrusive Investigations, including, without limitation, probes and/or borings, without Seller's prior written approval, which may be granted or denied in Seller's reasonable discretion. Prior to the commencement of any Investigations as to any of the Properties, Purchaser shall obtain or cause Purchaser's Consultants to obtain, at Purchaser's sole cost and expense, a policy of general commercial liability insurance, with limits of not less than One Million and No/100 Dollars ($1,000,000.00) combined single limit per occurrence, for bodily injury and property damage liability, covering any and all liability of Purchaser with respect to or arising out of such Investigations, which shall name Seller, the Companies, Aero SeaTac and all lenders, including, without limitation, the Lenders, who then have an interest in the applicable Property, as an insured party, and shall be in form and of substance, and issued by an insurance company, reasonably satisfactory to Seller. Any damage caused to the Properties due to any Investigations shall be repaired by Purchaser at its sole cost and expense, if Purchaser shall elect not to consummate the transactions contemplated hereby, pursuant to the provisions of this Agreement. Also, Purchaser shall indemnify, defend and hold harmless Seller, the Companies, Aero SeaTac, all lenders, including, without limitation, the Lenders, who then have an interest in applicable Property, from and against any Losses that Seller shall suffer due to any claim or cause of action that shall have arisen out of or resulted from any Investigations, which indemnification, defense and hold harmless agreements shall not be merged into this Agreement and shall survive the termination of this Agreement, if applicable; provided, however, that the foregoing indemnity shall not apply to the mere discovery of a pre-existing condition. For purposes of this Agreement, the term "Losses" shall be deemed to mean any claim, cause of action, loss, damage, liability, cost and expense, including, without limitation, reasonable attorneys' fees and court costs (collectively, "Losses"). 2.3 Seller shall be entitled to have a representative of Seller present during any meetings between Purchaser and any governmental official or representative regarding Hazardous Materials (as defined below) in, at, on, about and/or under, or the environmental condition of, any of the Properties, 14 as well as advance written notice of any such meeting at least one (1) business day prior to the date thereof. 2.4 Intentionally Omitted. 2.5 If Purchaser shall not have delivered to Seller, on or prior to 9:00 a.m. (San Francisco, California time) on October 7, 2003 (the period between the Effective Date and such date, "Due Diligence Period"), written notice (the "Approval Notice") that Purchaser shall have waived its right to terminate this Agreement, pursuant to the provisions of this Paragraph 2.5, which election shall be in Purchaser's sole and absolute discretion, then this Agreement automatically shall be terminated as of 9:00 a.m. (San Francisco, California time) on October 7, 2003 and the Earnest Money shall be returned to Purchaser, whereupon no party shall have any further obligations to the other hereunder, except as otherwise herein provided; provided, however, that upon the full execution of this Agreement by Purchaser and Seller (and the execution of this Agreement by the Joinder Parties (as herein defined)) and delivery of the fully executed Agreement by Purchaser to Seller prior to 9:00 a.m. (San Francisco, California time) on October 7, 2003, Purchaser shall be deemed to have delivered the Approval Notice in accordance with the provisions hereof. 2.6 Purchaser acknowledges that, if Purchaser shall have delivered (or is deemed to have delivered) the Approval Notice to Seller, prior to the expiration of the Due Diligence Period, then, pursuant to the provisions of Paragraph 2.5 but subject to the provisions of Paragraphs 6.1, 6.2 and 6.3, and subject to Purchaser's ongoing right to update any of its reports, studies or investigations conducted with respect to any Property if, by the applicable Closing Date, such reports, studies or investigations will be more than sixty (60) days old (provided that Purchaser may update such reports, studies and investigations for the sole purpose of confirming the satisfaction of the covenants, conditions, representations and warranties contained in this Agreement), Purchaser shall be deemed to have (a) conducted (or shall have waived its right to conduct), to its satisfaction, all Investigations, including, without limitation, those as to Hazardous Materials, (b) reviewed, examined, evaluated and verified, to its satisfaction, all of the Due Diligence Items (as hereinafter defined) and the results of the Investigations, including, without limitation, Purchaser's satisfaction as to the assignability of the Interests from Seattle - II to Purchaser and/or the Approved Assignee(s), as hereby contemplated, and (c) become familiar with the physical condition of all of the Properties. 2.7 Except as otherwise herein provided, (i) any reports, repairs and/or alterations with respect to the Properties required by Purchaser, including, without limitation, the cost and expense thereof, shall be the sole responsibility of Purchaser, and (ii) Purchaser hereby agrees that there shall be no obligation on the part of Seller to make any reports, changes, alterations or repairs, cure any violations of applicable law or comply with the requirements of any insurer, with respect to any of the Properties. 2.8 Radon is a naturally occurring radioactive gas that, when it has accumulated in a building in sufficient quantities, may present health risks to persons who are exposed to it over time. Levels of radon that exceed federal and state guidelines have been found in buildings in Florida. Additional information regarding radon and radon testing may be obtained from your county public health department. With respect to the Improvements situate in the State of Florida, Purchaser acknowledges receipt of the energy efficiency disclosure brochure described in Section 553.996 of the 15 Florida Statutes.

ARTICLE 4 CONDITIONS PRECEDENT 4.1 Purchaser's obligation to consummate the transactions contemplated hereby shall be subject to satisfaction of all of the following (collectively, "Purchaser's Conditions Precedent"): (a) On the applicable Closing Date, neither Seller nor Aero SeaTac shall be in material default in the performance of any material covenant or agreement to be performed by Seller hereunder or under any of the (i) Leases, (ii) New Leases (as defined below), if applicable, (iii) Service Contracts and/or (iv) New Service Contracts (as defined below), if applicable, or in default under any of the documents and/or instruments evidencing and/or securing the Assumed Loans (collectively, the "Assumed Loan Documents") or any of the ground leases (the "Ground Leases") previously entered into, between various ground lessors (collectively, the "Ground Lessors"), and the Leasing Companies and Aero SeaTac (collectively, the "Ground Lessees"), as the case may be, as to the respective Properties leased by such Ground Lessees, upon the terms and conditions thereof, as the case may be. (b) All representations and warranties made by Seller in this Agreement shall be true and correct in all material respects as of the Effective Date and as of the applicable Closing Date. (c) On the applicable Closing Date, there shall exist no pending action, suit or proceeding with respect to Seller and/or Aero SeaTac, before any court or administrative agency, which shall seek to restrain or prohibit, in whole or part, or to obtain damages or a discovery order with respect to, this Agreement or the consummation of the transactions contemplated hereby, other than any of the foregoing that shall exist between Purchaser and Seller with respect to this Agreement and/or the transactions contemplated hereby. (d) On or prior to the applicable Closing Date, Seller shall have delivered to Purchaser estoppel letters substantially in the form of Exhibit C attached hereto (as modified to address specific concerns arising as a result of Purchaser's review of the Leases) dated not more than forty five (45) days prior to the applicable Closing that shall have been executed by tenants under leases for space in the Improvements ("Tenants") that, as of such Closing, shall occupy, collectively, at least seventy-five percent (75%) of the total square footage of the Improvements on each Property being conveyed, directly or indirectly, at such Closing, and at least eighty percent (80%) of the aggregate square footage of all of the Improvements being conveyed, directly or indirectly, at such Closing (provided, that the 80% figure shall be used if there is only one Property being conveyed at a particular Closing), and shall include estoppels from all Tenants occupying as of such Closing Date twenty-five thousand (25,000) square feet or more of the square footage of the 17 Improvements on any single Property being conveyed, directly or indirectly, at such Closing (each such Tenant, a "Major Tenant"); provided, however, that, if Seller only shall have delivered to Purchaser such estoppel letters from Tenants under leases for space in the Improvements being conveyed, directly or indirectly, at such Closing, that, as of the Closing Date, shall encompass less than ninety percent (90%) of the aggregate square footage of all of the Improvements being conveyed, directly or indirectly, at such Closing, then Seller shall deliver to Purchaser an estoppel letter, which shall be substantially in the form of Exhibit F attached hereto, executed by Seller, with respect to Tenants selected by Purchaser occupying the square footage of the Improvements being conveyed, directly or indirectly, at such Closing, equal to the difference between ninety percent (90%) of the aggregate square footage of all of the Improvements being conveyed, directly or indirectly, at such Closing, and the square footage of the Improvements covered by the estoppel letters delivered to Purchaser by Seller and executed by Tenants with respect to the applicable Closing, pursuant to the provisions of this paragraph. If all of the estoppel letters required to have been delivered, pursuant to the provisions of this paragraph, shall not have been so delivered on a timely basis, either Purchaser or Seller shall have the right to extend the applicable Closing Date for up to ten (10) business days to provide additional time to obtain such estoppel letters, whereupon Seller shall use commercially reasonable efforts, at no cost or liability to Seller, to obtain such estoppel letters on or prior to the applicable Closing Date. With respect to any Seller executed estoppel delivered to Purchaser, Seller shall have the right to substitute therefor an estoppel executed by the applicable Tenant which satisfies the requirements for such tenant estoppel as provided above in this paragraph and in such event the applicable Seller executed estoppel shall be of no further force or effect. (e) Unless otherwise agreed to in writing by Purchaser, as of the date of the First Closing, Seller or the Companies, other than the Assumed Debt Companies, shall have defeased or repaid, in full, at Seller's expense, all of the loans previously made by various lenders to the Companies, other than the Assumed Debt Companies, as the case may be, which loans are more particularly described in the Side Letter Agreement (collectively, the "Other Loans").

(h) As of the applicable Closing Date, there shall have been no material adverse changes since the end of the Due Diligence Period in the physical condition of any of the Properties 18 being conveyed, directly or indirectly, at such Closing, subject to ordinary wear and tear and the provisions of Article 10. (i) With respect to any Closing occurring after the Second Closing (other than with respect to the Properties owned by New York and New York - II), as of the applicable Closing Date, there shall have been no material adverse changes in the tenant condition of any of the Properties being conveyed, directly or indirectly, at such Closing since the end of the Due Diligence Period. For purposes of this Subparagraph 4.1(i), "material adverse changes in the tenant condition" shall mean a material adverse change in the tenant condition of any Major Tenant as reasonably determined by Purchaser (e.g., the bankruptcy of a Major Tenant, a material adverse change in the financial condition of a Major Tenant as reasonably determined by Purchaser or the material default by a Major Tenant under its lease where such default is not cured within any applicable cure period). In the event that a material adverse change in the tenant condition of a Major Tenant occurs, Purchaser may elect not to purchase the affected Property, this Agreement shall terminate with respect to the affected Property, the Purchase Price shall be reduced by the amount of the Property Allocation applicable to such Property, the Earnest Money allocated to such Property pursuant to the Earnest Money Allocations shall be returned to Purchaser, and Purchaser and Seller shall thereafter have no further obligation or liability with respect to said Property, except as set forth herein. The parties agree that it shall not be a material adverse change in the tenant condition if a property tax assessment results in an increase in the taxes that may be payable by a tenant under its lease; provided, however, that this sentence shall not serve as a limitation or waiver of any other right or Condition Precedent expressly granted herein to Purchaser, including, without limitation, the Condition Precedent set forth in Paragraph 4.1(d) hereof.

The Ground Lessor Consents shall also include an estoppel from each such Ground Lessor, all of which shall be in form and of substance reasonably satisfactory to Seller and Purchaser (provided, if the form of such estoppel is contained in the applicable Ground Lease, the parties shall accept such form from the applicable Ground Lessor as is so provided in such documents; provided, however that the foregoing proviso shall not affect, limit or negate Purchaser's requirement that the applicable Ground Lessor Consents contain the acknowledgements and requirements provided in clauses (i) and (iii) of this Subparagraph (o)).

(d) Purchaser has received a copy of (i) the Florida Energy Efficient Rating System Brochure and (ii) the California Natural Hazards Disclosure Report, with respect to each tax parcel that comprises each of the Properties located in the State of California. All of the representations and warranties contained in this Paragraph 6.3 shall be deemed to be remade by Purchaser as of the applicable Closing Date, which representations and warranties shall not be merged into this Agreement and shall survive the Closing or the termination of this Agreement, as applicable, and run in favor of, and benefit, Seller and its successors and assigns. 6.4 All representations and warranties by the respective parties contained herein or made in writing pursuant to this Agreement are intended to and shall remain true and correct as of the time of the applicable Closing, shall be deemed to be material, and, together with all conditions, covenants and indemnities made by the respective parties contained herein or made in writing pursuant to this Agreement (except as otherwise expressly limited or expanded by the terms of this Agreement), shall survive the execution and delivery of this Agreement and the applicable Closing; provided, however, that notwithstanding the foregoing, Seller's and Purchaser's representations and warranties shall be limited as follows: (i) the Property Representations and Purchaser's representation and warranty set forth in Subparagraph 6.3(a) shall survive the applicable Closing for a period of one (1) year, and (ii) the Entity/PILOT/ICIP Representations, and Purchaser's representations and warranties set forth in 34 Subparagraphs 6.3(b) and 6.3(c) shall have unlimited survival (except as limited by any applicable statute of limitations). For purposes hereof, any reference to "knowledge" or "best knowledge" of Seller shall mean the actual knowledge as of the date of such statement of Doug Krahnke (with respect to Property related matters only), Jerry Powalish (with respect to construction related matters only), Dan Johnson (with respect to construction related matters only), Alexander Kurrelmeier, Craig Arnson, Joseph Perlmutter, Jacob Citrin and Norman Perlmutter (and any individuals who hereafter shall assume all or substantially all of the duties and responsibilities of such individuals), without any independent duty of diligence or investigation or any constructive, imputed and/or deemed knowledge, which individuals, under no circumstances, shall be subject to any personal liability of any kind whatsoever. Notwithstanding anything to the contrary herein contained, Purchaser shall not assume any liability with respect to any construction defects due to Purchaser having acquired an Interest in Aero SeaTac, which liability Purchaser would not have assumed had Purchaser acquired the Seattle - II Property in fee simple rather than by means of acquiring an Interest. Any liability for such construction defects shall be borne by Seller, subject to the provisions of Paragraph 12.9 hereof. Seller shall retain, on a non-exclusive basis with Purchaser, all rights to seek recovery of these amounts from any third party that actually may have been responsible for any such losses, and Purchaser shall cooperate with those efforts at no cost or expense to Purchaser. Notwithstanding anything to the contrary herein contained, to the extent that Purchaser shall have actual knowledge or shall be "deemed to have known" prior to the expiration of the Due Diligence Period that any of the representations and/or warranties made herein by Seller shall be inaccurate, untrue and/or incorrect in any respect, such representations and warranties shall be deemed to have been modified to reflect such knowledge or deemed knowledge, as the case may be. For purposes of this Agreement, Purchaser shall be "deemed to have known" of the existence of a fact or circumstance, to the extent that (a) this Agreement, (b) the Due Diligence Materials listed on Exhibit E, (c) any estoppel certificate executed by any Tenant or Seller and delivered to Purchaser, (d) the Side Letter Agreement, or (e) any tests, studies, reports, analyses, appraisals, verifications and/or evaluations prepared by or for Purchaser or any of Purchaser's Consultants and delivered to Purchaser, or otherwise obtained by Purchaser or any of Purchaser's Consultants, shall disclose a fact or circumstance, or otherwise contain information, that shall be inconsistent in any way with any representation and/or warranty made herein by Seller. If, after the expiration of the Due Diligence Period, but prior to the applicable Closing, Purchaser shall know or be deemed to have known that any of the representations and/or warranties made herein by Seller shall be untrue, inaccurate and/or incorrect in any material respect, Purchaser shall give Seller written notice thereof within five (5) business days of obtaining actual knowledge (but, in any event, prior to the applicable Closing). If, at or prior to the applicable Closing, Seller shall obtain actual knowledge that any of the representations or warranties made herein by Seller shall be untrue, inaccurate and/or incorrect in any material respect, Seller shall give Purchaser written notice thereof within five (5) business days of obtaining such knowledge (but, in any event, prior to the applicable Closing). In either such event, Seller shall have the right to cure such breach and shall be entitled to a reasonable adjournment of the Closing (not to exceed ten (10) business days) for such purpose. On the other hand, if Seller shall be unable to so cure any such breach, or, if Seller shall elect, in its sole and absolute discretion, not to cure such breach, by giving Purchaser written notice of such 35 election, within two (2) business days of obtaining actual knowledge of such breach, then Purchaser, as its sole and exclusive remedy, as a result of any such breach, shall elect, by giving written notice to Seller, within one (1) business day of receiving written notice from Seller that Seller shall have elected not to cure such breach, to either (a) waive such breach and consummate the transactions contemplated hereby, without any reduction of or credit against the Purchase Price, or (b) terminate this Agreement with respect to the applicable Property or Properties unless such uncured breach was a wilful and intentional breach by Seller in which event Purchaser may terminate this Agreement with respect to all of the Properties, as of the date of such notice, and receive a refund of the Earnest Money allocated to the applicable Properties, whereupon no party shall have any further obligations to the other hereunder, except as otherwise herein provided including, without limitation, the provisions of Paragraph 7.1. Notwithstanding anything to the contrary herein contained, the liability of Seller for any breach(es) of the representations and warranties made by Seller herein or in any documents and/or instruments executed by Seller at the Closing shall be limited as set forth in Paragraph 12.9; provided, however, that, if a Closing shall occur, Purchaser hereby expressly waives, relinquishes and releases any right and/or remedy available to it at law, in equity and/or under this Agreement, to make a claim against Seller for damages that Purchaser may incur with respect to the applicable breach(es), or to rescind this Agreement and the transactions contemplated by this Agreement, as a result of any of the fact that any of such representations and/or warranties shall have been untrue, inaccurate and/or incorrect, if Purchaser actually knew or shall be deemed to have known such representation or warranty was untrue, inaccurate and/or incorrect at the time of the applicable Closing. Purchaser acknowledges and agrees that the Due Diligence Period provides Purchaser adequate opportunity to inspect and investigate each and every aspect of the Properties and the Interests. Purchaser acknowledges and agrees that, except for Seller's express representations and warranties set forth in this Agreement, Purchaser is purchasing the Interests, Sale Properties or leasehold interests in the Leased Properties based solely on Purchaser's inspection and investigation of the Properties and the Interests, Sale Properties and the Leased Properties, or its opportunity to do so, and Purchaser is purchasing the Interests, Sale Properties and leasehold interests in the Leased Properties without relying on any representations or warranties, express or implied, of any kind, other than as specifically set forth in this Agreement. Without limiting the foregoing, Purchaser expressly acknowledges and agrees that, except for Seller's express representations and warranties set forth in this Agreement, neither Seller nor Seller's agents have made any representations or warranties as to any matters concerning the Properties, including, but not limited to, its intended use, the condition of the Properties, square footage, layout, development rights and exactions, permissible uses, utilities, zoning, soil, subsoil, drainage, compliance with applicable laws, the presence of Hazardous Materials or any other matters. 6.5 Seller hereby covenants and agrees with Purchaser that, from and after the Effective Date, Seller shall (and Seller shall cause Aero SeaTac to) conduct their respective businesses involving the Properties as follows, and during such period Seller shall (and Seller shall cause Aero SeaTac to) (except as otherwise herein provided to the contrary): (a) Continue, up to the applicable Closing, to operate, maintain, repair and/or replace the Properties in the same manner as on the Effective Date in all material respects, subject to ordinary wear and tear; provided, however, that none of Sellers or Aero SeaTac shall have any duty to repair, replace or restore any of the Properties upon any damage or 36 destruction, or condemnation, except as otherwise herein provided. (b) Refrain, (i) up to expiration of the Due Diligence Period from entering into any new or renegotiated lease (collectively, "New Leases") regarding the Properties, without the prior written approval of Purchaser, which approval shall not be unreasonably withheld, conditioned or delayed; provided, however, that, with respect to potential New Leases regarding the Properties to which Seattle, Seattle - IV and Seattle - V hold fee simple title (collectively, the "Seattle Properties"), and the Third Closing Holdback/Adjustment Properties, Seller only shall be required at least three (3) days prior to the expiration of the Due Diligence Period to (A) give Purchaser written notice of the economics of any potential New Lease, exclusive of the name of the prospective tenant thereunder, and (B) solicit feedback from Purchaser with respect to such potential New Lease, but Purchaser's approval of such potential New Lease shall not be required for Seller to execute any such potential New Lease, and (ii) from and after the expiration of the Due Diligence Period, from entering into any New Lease regarding any Property, including, without limitation, the Seattle Properties and the Third Closing Holdback/Adjustment Properties, without the prior written approval of Purchaser; provided, however, that, any such potential New Lease for vacant space in any Improvement shall be deemed to have been approved by Purchaser, if Purchaser shall not have notified Seller in writing of Purchaser's approval or disapproval, if applicable, of any such potential New Lease, within five (5) business days after receipt thereof by Purchaser. In addition, Purchaser shall not unreasonably withhold its consent to a potential New Lease, if such potential New Lease shall (a) be on a form substantially similar to Seller's form lease for such Improvement that is in effect as of the Effective Date (and Seller shall deliver to Purchaser a certified copy of each such form lease at the First Closing) without material modifications, and (b) contain such economic and other provisions for such vacant space as shall be within the applicable leasing parameters set forth on the Side Letter Agreement; provided, however, that notwithstanding the foregoing, Seller shall obtain Purchaser's approval of the proposed new tenant or tenants, based on Purchaser's evaluation of (1) the financial qualifications of the new tenant, (3) the proposed use of the Property by the new tenant, (2) the space plan and configuration requested by the new tenant (including a designation of the office and warehouse layout), approval of which configuration shall, notwithstanding anything to the contrary contained in this Agreement, be in Purchaser's sole discretion, (4) to the extent the applicable lease allocates parking spaces, the number of parking spaces to be allocated at the Property to such tenant, (5) at the New York Properties, whether such tenant will have employees that will qualify as "Facility Tenant Employees" (as such term is defined in the Ground Leases entered into by New York, New York - I, New York - II and New York - III) and (6) whether or not said new tenant is reasonably compatible with other tenants and uses on the Property. Seller shall deliver to Purchaser a fully signed counterpart of any New Lease promptly upon the full execution and delivery thereof by the parties thereto; and provided, further, that without limiting Purchaser's right to disapprove a potential New Lease on the basis of a tenant's lack of creditworthiness in Purchaser's reasonable discretion, Seller agrees that Purchaser shall have the right to condition its approval of any potential New Lease on Seller waiving its right to receive an Earnout Amount with respect to such potential New Lease, and Purchaser shall advise Seller that it requires such waiver at the time that Purchaser approves the potential New 37 Lease. (c) Refrain, up to the Closing, from entering into or amending any agreement (other than any New Lease, subject to the terms and conditions hereof) regarding the Properties, without having first obtained the prior written consent of Purchaser thereto in each instance, which consent shall not be unreasonably withheld, conditioned or delayed, unless such contract could be terminated by the relevant Company and/or Aero SeaTac, without penalty or termination fee (unless paid by the relevant Company or Aero SeaTac, as the case may be, prior to the applicable Closing), upon not more than thirty (30) days' notice (collectively, "New Service Contracts"); provided, however, that, if Purchaser shall not have notified Seller in writing of Purchaser's approval or disapproval of any such agreement, within five (5) business days after receipt thereof, then the same shall be deemed to have been approved by Purchaser. Seller shall deliver to Purchaser a fully signed counterpart of any New Service Contract promptly upon the full execution and delivery thereof by the parties thereto. (d) Maintain, through the Closing, the insurance coverage that is in effect with respect to the Properties as of the Effective Date, so long as such coverage continues to be available at a commercially reasonable rate. (e) Be solely responsible for all rent abatements, tenant improvement costs, leasing commissions and any other monetary concessions that shall be the obligation of the landlord (collectively, "Landlord Obligations") under any (i) lease entered into prior to the Effective Date, with respect to any space in the Improvements, including, without limitation, the work to be performed with respect to the space described on the Side Letter Agreement ("Other Landlord Obligation Space"), and (ii) New Lease entered into on or after the Effective Date, (A) with respect to any Vacant Space (subject to Paragraph 1.4) or (B) with respect to any vacant space other than Vacant Space (which is addressed in Paragraph 1.4) as follows: (1) Seller shall be responsible for any rent abatements applicable to any portion of the term of a New Lease for such vacant space occurring prior to the applicable Closing (and Purchaser shall be responsible for the rent abatements under such New Lease applicable to the portion of the term of such New Lease occurring from and after the applicable Closing) and Seller and Purchaser shall each be responsible for their prorata share of the other Landlord Obligations attributable to such New Lease based on the relative portions of the lease term occurring during the Seller's and the Purchaser's period of ownership of the applicable Property, respectively, and (2) Seller shall not be responsible (and Purchaser shall be responsible) for any leasing commissions that shall be the obligation of the landlord under any lease(s) entered into prior to, on or after the Effective Date (and prior to the Determination Date for the applicable Property, if applicable) in accordance with this Agreement, with respect to any space in the Improvements, but only to the extent such commissions (i) are described on the Side Letter Agreement or, with respect to New Leases, are otherwise approved by Purchaser in writing at such time as Purchaser approves of the applicable New Lease, and (ii) are payable only as a result of any options, including, without limitation, extension, renewal and/or expansion options, exercised, on or after the Effective Date, by a tenant under any such lease; provided, however, that notwithstanding the foregoing, Seller shall not be responsible for any such leasing commissions described in the foregoing clause (2) 38 applicable to any space at a Holdback/Adjustment Property to the extent such commission arises as a result of a commission agreement entered into after the Determination Date for such Property. The parties' respective obligations under this Paragraph 6.5(e) shall not be merged into this Agreement and shall survive the applicable Closing.

Seller shall substantially complete, as of the applicable Closing, all construction with respect to the initial development and construction of the Improvements (other than the tenant improvements at the NY III Property and the NY IV Property) to be completed with respect to the NY III Property and the NY IV Property and the HICTC Property, as contemplated hereby (except for so called "punchlist items," i.e., minor details of construction, decoration or mechanical adjustments which do not materially interfere with occupancy of the applicable Property and which shall be diligently completed by Seller). In addition, Seller shall complete and make operational, at Seller's sole cost and expense, on or before the Closing for the New York Properties, the infrared and other security systems that are installed but not intended to be operational at the Properties owned by New York - I, New York - II, New York -III and New York - IV (collectively, the "New York Properties") until all of the Improvements (other than the tenant improvements at the NY III Property and the NY IV Property) located thereon are completed. (g) Refrain from modifying, amending or terminating any of the Assumed Loan Documents or the Ground Leases or any of the organizational documents, including, without limitation, the operating agreement, of Aero SeaTac, and to refrain from dissolving Aero SeaTac. (h) Refrain from taking any action that could result in a change of zoning or a change to any of the entitlements affecting any of the Properties and to refrain from permitting or causing any new liens or encumbrances (with the exception of any new easements which are reasonably approved by Purchaser) to affect any of the Properties. (i) Refrain from taking any action that would cause any of Seller's representations and warranties contained in this Agreement to become untrue or incorrect in any material respect.

For all purposes of this Agreement, the term "Earnout Amount" shall have the meaning ascribed to such term in the Earnout Agreement, and the term Earnout Agreement shall mean the Earnout Agreement dated as of May 20, 2003, between Boston, as borrower, and LaSalle Bank National Association ("LaSalle"), as lender, with respect to the Assumed Loan made by LaSalle to Boston in the original principal amount of $51,000,000. In no event shall Purchaser have any liability to Seller in the event Seller is unable to receive all or any portion of the Earnout Amount from LaSalle. To the extent that Seller is not entitled to the full amount of the Earnout Amount and the applicable Lender applies all or any portion of the Earnout Amount to the applicable Assumed Loan, Seller shall be responsible for the payment of any Yield Maintenance Amount (as defined in the Earnout Agreement) arising as a result of such prepayment of the applicable Assumed Loan. The Earnout Amount shall not reduce the amount of the outstanding principal amount of the applicable Assumed Loan for the purposes of determining the amount of the Cash portion of the Purchase Price to be paid with respect to the applicable Property. The provisions of this Paragraph 6.7 shall not be merged into this Agreement and shall survive the applicable Closing. ARTICLE 7 DEFAULTS 7.1 If there shall be a default by Purchaser or Seller hereunder, and such default shall not have been cured within five (5) days after the non-defaulting party shall have given written notice thereof to the defaulting party, then the non-defaulting party, at its option, may (i) specifically enforce the terms and provisions of this Agreement against the other party (BUT NO OTHER ACTION, FOR DAMAGES, OR OTHERWISE, SHALL BE PERMITTED); provided, that Seller shall only be entitled to the remedy described in this clause (i) after the First Closing has been consummated (provided, that if specific performance is not available in the applicable jurisdiction through no fault of the Seller at the time that Seller seeks to enforce such specific performance, then only in such instance Seller shall be entitled to its damages as are available at law (but excluding any punitive damages) arising as a result of Purchaser's uncured failure to Close in breach of this Agreement as it relates solely to the specific Property or Properties located in the applicable jurisdiction which are not acquired by Purchaser as a result of Purchaser's uncured wrongful refusal to Close (in which event and notwithstanding anything to the contrary provided in this Paragraph 7.1 or in Paragraph 7.2, Seller shall not also be entitled to retain any portion of the Earnest Money allocable to the applicable Property or Properties for which Seller is seeking damages), or (ii) terminate its obligations under this Agreement with respect to the applicable Property or Properties unless such uncured breach was a wilful and intentional breach by the defaulting party in which event the non-defaulting party may terminate this Agreement with respect to all of the Properties, in either case by written notice thereof to the other party and such non-defaulting party shall receive a refund or the payment of the Earnest Money allocated to the applicable Properties (provided, however, that if Purchaser is the defaulting party and such default occurs at or prior to the First Closing, then the Seller shall only be entitled to receive a portion of the Earnest Money in the amount of Four Million Dollars and Purchaser shall receive a refund of the balance of the Earnest Money in the amount of Four Million Five Hundred Thousand Dollars), as the case may be, and if the non-defaulting party is the Purchaser, Seller shall reimburse to Purchaser its third party out-of-pocket 44 expenses incurred in connection with the transactions contemplated in this Agreement (not to exceed $400,000 in the aggregate), whereupon no party hereto shall have any further obligations to the other hereunder, except as otherwise herein provided. SELLER'S INITIALS: /S/ A.K. PURCHASER'S INITIALS: /S/ T.H. 7.2 IF THERE SHALL BE A DEFAULT BY PURCHASER HEREUNDER, AND SELLER SHALL ELECT TO TERMINATE ITS OBLIGATIONS UNDER THIS AGREEMENT, PURSUANT TO THE IMMEDIATELY PRECEDING PARAGRAPH, THE PARTIES AGREE THAT IT WOULD BE IMPRACTICAL AND EXTREMELY DIFFICULT TO ESTIMATE THE DAMAGES THAT SELLER MAY SUFFER AS A RESULT THEREOF. THUS, PURCHASER AND SELLER HEREBY DO AGREE THAT A REASONABLE ESTIMATE OF THE DAMAGES THAT SELLER WOULD SUFFER IN THE EVENT THAT PURCHASER SHALL DEFAULT AND FAIL TO COMPLETE THE TRANSACTIONS CONTEMPLATED HEREBY AND SELLER SHALL ELECT TO TERMINATE ITS OBLIGATIONS UNDER THIS AGREEMENT WOULD BE, AS SELLER'S SOLE AND EXCLUSIVE REMEDY (WHETHER AT LAW OR IN EQUITY), AN AMOUNT EQUAL TO THE EARNEST MONEY ALLOCATED TO THE APPLICABLE PROPERTIES (PROVIDED, HOWEVER, THAT IF SUCH DEFAULT OCCURS AT OR PRIOR TO THE FIRST CLOSING, THEN THE SELLER SHALL ONLY BE ENTITLED TO RECEIVE A PORTION OF THE EARNEST MONEY IN THE AMOUNT OF FOUR MILLION DOLLARS AND PURCHASER SHALL RECEIVE A REFUND OF THE BALANCE OF THE EARNEST MONEY IN THE AMOUNT OF FOUR MILLION FIVE HUNDRED THOUSAND DOLLARS), WHICH AMOUNT WOULD BE THE FULL, AGREED AND LIQUIDATED DAMAGES FOR SUCH DEFAULT BY PURCHASER UNDER SUCH CIRCUMSTANCES, AND ALL OTHER CLAIMS TO DAMAGES OR OTHER REMEDIES HEREIN EXPRESSLY SHALL BE WAIVED BY SELLER; PROVIDED, HOWEVER, THAT THE FOREGOING SHALL NOT LIMIT SELLER'S RIGHT TO RECEIVE REIMBURSEMENT FOR REASONABLE ATTORNEYS' FEES, AS HEREIN PROVIDED, OR WAIVE OR AFFECT PURCHASER'S INDEMNITY OBLIGATIONS UNDER THIS AGREEMENT. THE PAYMENT OF SUCH AMOUNT AS LIQUIDATED DAMAGES WOULD NOT BE INTENDED AS A FORFEITURE OR PENALTY, BUT RATHER, WOULD BE INTENDED TO CONSTITUTE LIQUIDATED DAMAGES TO SELLER. IN CONNECTION WITH THE FOREGOING, THE PARTIES RECOGNIZE THAT SELLER WILL INCUR EXPENSE IN CONNECTION WITH THE TRANSACTION CONTEMPLATED HEREBY AND THAT THE INTERESTS AND THE PROPERTIES WILL BE REMOVED FROM THE MARKET. NOTWITHSTANDING THE FOREGOING, BUT SUBJECT TO THE PROVISIONS OF PARAGRAPH 7.1 ABOVE, NOTHING HEREIN SHALL ACT TO REDUCE ANY RIGHTS OR REMEDIES OF SELLER AGAINST PURCHASER ARISING OUT OF ANY DEFAULT BY PURCHASER WITH RESPECT TO WHICH SELLER SHALL SPECIFICALLY ENFORCE THE TERMS AND PROVISIONS OF THIS AGREEMENT AGAINST PURCHASER.

ARTICLE 9 CLOSING ADJUSTMENTS Except as otherwise herein provided, the following items shall be paid, prorated and/or adjusted as of the close of business on the day prior to the Closing Date (the "Proration Date"), as follows: 9.1 All real estate taxes and all personal property taxes accruing with respect to the period ending on, but inclusive of, the Proration Date, and all penalties and interest thereon, and all certified and other special assessments affecting the Properties shall be paid in full by Seller (or credited to Purchaser) at Closing; provided, however, that, if any such certified and special assessments shall be pending or payable in installments, Seller only shall be responsible for paying the portion of such assessments accruing with respect to the period ending on, but inclusive of, the Proration Date. 9.2 Current real estate and personal property taxes shall be prorated as of the Proration Date, on an "accrual" basis in accordance with the standard closing practice of the county in which the Property, 48 with respect to which such item shall relate, is located. The parties hereby further do agree to re-prorate such real estate taxes promptly upon Purchaser's receipt of the actual tax bill for the tax year in question. In no event shall Seller be charged with or be responsible for any increase in such taxes resulting from the sale of the Interests or improvements made to the Properties after the Closing. Seller shall be entitled to retain the full amount of any tax refund received by Purchaser or Seller after the Closing and attributable to a period prior to the Closing, if such refund shall not be owed to Tenants pursuant to any leases. Purchaser promptly shall deliver the full amount of such tax refund to Seller, if the same shall have been received by Purchaser. The foregoing shall not be merged into this Agreement and shall survive the Closing. 9.3 Any non-cash security deposits shall be assigned (and all consents necessary to effectuate such assignment shall have been obtained) to Purchaser at the Closing, and Seller reasonably shall cooperate with Purchaser to change the named beneficiary under such security deposits, if, on the Proration Date, such deposits are not to be in the name of Purchaser or Aero SeaTac, as the case may be, all at Seller's sole cost and expense). In the event that as of a Closing, Seller has not obtained all necessary consents or otherwise effectuated the assignment of any non-cash security deposits with respect to any Properties acquired by Purchaser at such Closing, Seller shall use diligent commercially reasonable efforts to obtain such consents and cause such assignment to occur promptly after the Closing at Seller's expense. In addition, with respect to any such non-cash security deposits for which a consent has not been obtained or which has not been assigned as of the applicable Closing, if a tenant defaults under its lease and the landlord would have the right to apply any such non-cash security deposit, then Seller shall, upon Purchaser's written request, draw down on such non-cash security deposit and immediately deliver the proceeds therefrom to Purchaser and Purchaser agrees to indemnify, defend and hold Seller harmless against any Losses arising out of any claims by the applicable tenant arising as a result of the drawing down of such non-cash security deposit. 9.4 All of the following will be credited to Purchaser as of the Proration Date: (a) prepaid rent and rent paid for the balance of the month of the Closing, (b) cash security deposits made by Tenants, along with all interest thereon that shall be due to such Tenants, but not including interest earned thereon that shall belong to Seller or Aero SeaTac, if any, received by Seller or Aero SeaTac, as the case may be, prior to the Proration Date, (c) except as provided in Paragraph 6.6(b), the amount of any Landlord Obligations remaining unpaid as of (or with respect to rent abatements, the amount applicable to the period occurring after) the applicable Closing, and (d) utility costs, operating expenses, insurance costs, personal property expenses and real estate tax expenses (collectively, "Expense Contributions") that shall have been prepaid by Tenants. Any payment of rental obligations or Expense Contributions due, but not received, on the Proration Date, from Tenants, as well as any unbilled Expense Contributions accrued as of the Closing (collectively, the "Credit Items"), shall be paid by Purchaser to Seller as and when such amounts are collected from the applicable Tenants and after Purchaser is made current on all rental obligations and Expense Contributions due and payable following the Closing. Following the Closing Date, if Seller or Aero SeaTac shall receive any payments from any Tenant, all such payments, other than Credit Items, promptly shall be remitted to Purchaser, and Seller shall take all steps as reasonably shall be necessary to notify the remitting party that all future payments should be sent to Purchaser. Seller shall cooperate with Purchaser in its efforts to collect Credit Items, but shall not be required to take any direct action against any Tenant for such purpose (provided that, Seller shall be entitled to sue a Tenant or take any other actions to collect any Credit Items due to Seller (and not previously paid to Seller) so long as such suit or other action does not seek a termination of such Tenant's Lease or eviction of such Tenant). 49 When actual Expense Contributions shall have become known, Purchaser shall bill each Tenant, pursuant to its lease, for the additional amount, if any, owed by such Tenant as a result of non-payment or underpayment of such Tenant's share of Expense Contributions. Upon the collection of such amounts, the same shall be prorated between Seller and Purchaser based on each such Tenant's share of the amount of the applicable Expense Contribution incurred by each party and the collections from each of such Tenants of such Expense Contributions by each party, through and including the Proration Date. The amount of any refund or credit due to any Tenant as a result of collection by Seller or Aero SeaTac prior to the Closing Date of payments by any Tenant for Expense Contributions, which shall exceed the actual amount of such Expense Contributions owed by such Tenant for the period prior to the Closing Date, shall be paid by Seller to Purchaser promptly after such Expense Contributions shall have been determined. 9.5 Seller shall (and Seller shall cause Aero SeaTac to) pay all expenses necessary to repair, operate and maintain the Properties, as the case may be, in accordance with the ordinary course of its business up to the Proration Date, any such expenses which are prepaid by Seller (to the extent attributable to the period after the Proration Date) as of the Proration Date shall be credited to Seller and/or Aero SeaTac, as the case may be, and Purchaser and/or an Approved Assignee shall be responsible to pay such expenses incurred subsequent to the Proration Date. 9.6 Meters for utility services payable by Seller or Aero SeaTac, as the case may be, shall be read on or immediately prior to the Proration Date, or as close to the Closing as shall be possible, if a reading on the day prior to the Closing cannot be obtained, and the amounts due, as disclosed by such readings, shall be paid by Seller or credited to Purchaser. Otherwise, all utility charges and billings shall be prorated using the bill for the calendar month immediately preceding the Proration Date. Any security or service deposits delivered by the Companies or Aero SeaTac to utility providers, and any interest required to be paid thereon, shall be and remain the sole property of Seller, and any refund of such security deposits shall be made directly to Seller, except to the extent such deposits shall have been assigned to Purchaser and/or the Approved Assignee(s) by Seller, in which case, Purchaser shall be debited and Seller shall be credited the amount of such assigned deposits. 9.7 Seller shall bear and pay (a) the charges to comply with the terms of Paragraph 3.1, (b) additional title insurance premiums charged in connection with issuance to a Lender of any loan policy(ies) of title insurance (and endorsements thereto), (c) all fees, costs and/or expenses, including, without limitation, mortgage recording taxes, if applicable, imposed in connection with, as applicable, the (i) written consent of each Lender and each Ground Lessor, as the case may be, to the relevant transactions contemplated hereby, (ii) assumption of the Assumed Loans, the Loan Guarantees, the Ground Leases and/or the Ground Lease Guarantees, and/or (iii) release of all of the Loan Guarantors from all of the Loan Guarantees and/or all of the Ground Lease Guarantors from all of the Ground Lease Guarantees, all as contemplated hereby, including, without limitation, all assignment and/or assumption fees charged by any Lender or Ground Lessor or EDC. 9.8 Purchaser shall bear and pay all costs and expenses incurred in connection with (a) the Investigations, including, without limitation, the preparation of any Phase I, (b) any Updated Survey and/or the issuance to any lender, other than a Lender, of any loan policy(ies) of title insurance (and endorsements thereto). 50 9.9 Except as otherwise herein provided, each party shall be responsible for, and shall bear, any and all costs and expenses incurred by either of them or their respective employees, agents and/or representatives in connection with the transactions contemplated hereby, including, without limitation, those of their respective attorneys, accountants and consultants, which obligations shall not merge into this Agreement and shall survive the Closing or the termination of this Agreement, as applicable. 9.10 All costs relating directly to any escrow and/or closing services provided in connection with the transactions contemplated hereby shall be divided equally between the parties. Any and all (a) premiums for the Title Policies and the title update charges in connection therewith, (b) state, county and local transfer, documentary and/or stamp taxes imposed regarding the transactions contemplated hereby, (c) recording fees and (d) other items that are customarily prorated in transactions similar to the transactions contemplated hereby, but have not been herein addressed, will be prorated as of the Proration Date in accordance with the standard closing practice of the county in which the Property, with respect to which such item shall relate, is located as such standard closing practice is set forth in the Side Letter Agreement. 9.11 Any non-delinquent bonds that relate to items other than real estate taxes, that, as of the Closing Date, shall be a current lien against any of the Properties shall be prorated as of the Closing Date. 9.12 All adjustments made pursuant to this Article 9 shall be paid in cash or credited against the cash portion of the Purchase Price at the Closing. All adjustments made pursuant to this Article 9 shall be made on the basis of a 365 day year and, to the extent reasonably practicable, such prorations shall be made at the Closing. To the extent any such prorations cannot be made at the Closing, the same shall be adjusted and completed after the Closing as and when complete information shall become available. Seller and Purchaser each agrees to cooperate and use its commercially reasonable efforts to complete such prorations no later than thirty (30) days after the Closing Date. Seller and Purchaser each shall use its commercially reasonable efforts prior to the Closing to prepare a schedule of prorations that shall cover current monthly rent, prepaid rent, security deposits, utility charges, operating expenses, if applicable, and real property taxes, so that such prorations can be made at the Closing. 9.13 Subject to the provisions of Paragraph 12.9, each party hereby agrees to defend, indemnify and forever hold harmless the other, from and against any Losses that such other party shall sustain by reason of the failure of the indemnifying party to pay the amounts it shall be required to pay or to take the actions it is required to take on a timely basis, pursuant to this Article 9, which indemnifications, defenses and hold harmless agreements shall not be merged into this Agreement and shall survive the Closing. ARTICLE 10 FIRE DAMAGE AND CONDEMNATION If, prior to the Closing Date, any portion of a particular Property shall have been damaged or destroyed by fire or other casualty in an amount exceeding One Million Dollars ($1,000,000), as determined by an insurance adjuster mutually satisfactory to Seller and Purchaser (which insurance adjuster shall have at least ten (10) years experience adjusting claims relating to similar commercial properties in the metropolitan area in which the applicable Property is located and who is not affiliated 51 with either party and who has not been engaged by either party within the previous two (2) year period; provided, that if the parties cannot agree on such an adjuster within twenty (20) days after Seller notifies Purchaser of the occurrence of the applicable casualty, the parties shall request that the local JAMS or equivalent mediation company select such an insurance adjuster meeting the aforesaid requirements), or written notice shall have been received by Seller, of any action, suit or proceeding to condemn or take all or any substantial part of a particular Property (whether a substantial part of a particular Property is affected shall be reasonably determined by Purchaser) under the power of eminent domain, Seller promptly shall notify Purchaser thereof in writing, and Purchaser, by giving Seller written notice thereof, within the earlier to occur of (a) the date that shall be thirty (30) days after receiving Seller's written notice of such fire or casualty, or such condemnation or taking (or ten (10) days after receiving the insurance adjuster's determination of the casualty amount, if later), and (b) the Closing Date, shall have the right to terminate its obligations under this Agreement and receive a refund of the Earnest Money, whereupon no party hereto shall have any further obligations to the other hereunder, except as otherwise herein provided; provided, however, that in the event the damage or casualty occurs at any time after the First Closing, Purchaser may elect not to purchase the affected Property only, in which event this Agreement shall terminate with respect to the affected Property only, the Purchase Price shall be reduced by the Property Allocation applicable to such Property, the Earnest Money allocated to such Property pursuant to the Earnest Money Allocations shall be returned to Purchaser, and Purchaser and Seller shall thereafter have no further obligation or liability with respect to said affected Property, except as set forth herein. If the damage or destruction caused by a fire or other casualty shall be such that Purchaser shall not be entitled, or shall not elect, to terminate this Agreement, pursuant to this Article 10, then (i) the transactions contemplated hereby shall be consummated as herein provided, (ii) there shall be credited against the Purchase Price an amount equal to the estimated cost to repair or restore the damage not so repaired or restored by Seller as of the Closing, together with an amount equal to the anticipated rental loss for the period subsequent to the Closing, if applicable, the amount of which credit shall be reduced by an amount equal to the insurance proceeds that are made available to Purchaser at the Closing to cover such loss(es), if applicable, and (iii) the Closing Date shall be extended for such reasonable period of time (not to exceed thirty (30) days) to enable the aforesaid adjuster to determine the amount of such damage, if applicable. The amount to be credited against the Purchase Price, pursuant to the foregoing sentence, shall be determined by the aforesaid adjuster. If, in the case of a condemnation or taking, Purchaser shall not be entitled, or have elected, to terminate its obligations hereunder, pursuant to this Article 10, and the corresponding condemnation award has been paid to the relevant Company or Aero SeaTac, Purchaser shall receive, on the applicable Closing Date, a credit towards the Purchase Price equal to the amount of the award received by such Company or Aero SeaTac. If, in the case of a condemnation or taking, Purchaser shall not be entitled, or have elected, to terminate its obligations hereunder, pursuant to this Article 10, and the corresponding condemnation award shall not have been paid to the relevant Company or Aero SeaTac, as the case may be, Purchaser shall receive, on the Closing Date an assignment of the entire amount of such corresponding condemnation award, and the Purchase Price shall be the full amount herein provided. The agreements contained in this Article 10 shall not be merged into this Agreement and shall survive the Closing.

This Agreement shall be governed by and construed according to the laws of the State of California. 12.8 Subject to the provisions of Paragraph 12.20, both Seller and Purchaser shall not, and shall 54 not permit any broker, finder or agent to, publicize the transactions contemplated hereby in any way and shall treat the same with confidentiality. 12.9 It is expressly understood and agreed that, notwithstanding anything to the contrary herein contained, from and after the Effective Date, the representations, warranties, covenants, indemnities, undertakings and agreements made by Seller hereunder, or under any of the documents executed and delivered by Seller at the Closing, shall not be for the purpose and/or with the intention of binding Seller or any of the Seller's Parties in their individual capacities, but rather, solely for the purpose of binding (and shall be enforceable against), after the Closing, Seller's assets only, and that no personal liability or personal responsibility shall be assumed by, or shall at any time be asserted or enforceable against, any of the Seller's Parties in their individual capacities, after the Closing, on account of any representation, warranty, covenant, undertaking, indemnity or agreement of Seller, either express or implied, all such personal liability or responsibility, if any, being expressly waived and released by Purchaser and by all persons claiming by, through or under Purchaser. Notwithstanding anything to the contrary contained in this Paragraph 12.9 or elsewhere in this Agreement, (i) if Seller's assets are not sufficient to satisfy any claim by Purchaser made on account of any representation, warranty, covenant, undertaking, indemnity or agreement of Seller, then Purchaser shall be entitled to pursue collection of any such claims against the Seller's Parties to the extent of any distributions of the Cash portion of the Purchase Price made to such Seller's Parties; provided that each of the Seller's Parties shall only be responsible for payment of such claim to the extent of its pro rata share of such distributions actually received by all of the Seller's Parties with respect to the particular Property for which a particular claim relates (provided that for the purposes of this clause (i) the New York Properties shall be deemed to be one Property), and (ii) Seller's and the Seller's Parties liability under this Paragraph 12.9 with respect to Purchaser's claims relating to a particular Property shall be limited to the amount of the Property Allocation for such Property (provided that for the purposes of this clause (ii) the New York Properties shall be deemed to be one Property). The provisions of this Paragraph 12.9 shall not be merged into this Agreement and shall survive the Closing. 12.10 Purchaser hereby agrees to cooperate with Seller, at no cost or liability to Purchaser, and subject to the provisions contained herein, in connection with any attempts on the part of the Seller to recover from any third party any amounts for which Purchaser shall have received a credit from Seller, pursuant to the terms and conditions of this Agreement, where such credit relates to an obligation of Seller to indemnify Purchaser or otherwise pay for the cost of any claims that relate to the acts of such third parties. 12.12 Both parties to this Agreement having participated fully and equally in the negotiation and preparation hereof, this Agreement shall not be more strictly construed, or any ambiguities within this Agreement resolved, against either party hereto. 12.13 If an event specified to occur herein falls on a Saturday or Sunday, or on a day on which banking institutions in the State of Illinois or California are authorized by law to close, then such event shall occur on the next day that is not a Saturday or Sunday, or on a day on which banking institutions in the State of Illinois or California are located are authorized by law to close. 12.14 In connection with any litigation arising out of this Agreement, the prevailing party shall be entitled to recover all of its reasonable attorneys' fees and costs, including, without limitation, all fees and costs incurred prior to and at all trial and appellate levels. 55 12.15 This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, legal representatives, successors and permitted assigns. 12.16 This Agreement may be signed in counterparts, which, together, shall be deemed to be an original and shall constitute one and the same instrument. Counterparts of this Agreement also may be transmitted by facsimile copier, which, together, shall be deemed to be an original. 12.17 Purchaser may not assign this Agreement, without the prior written consent of Seller, unless (a) Purchaser first shall have notified Seller in writing of such assignment (and Seller shall hereby be deemed to have been notified of Purchaser's intended assignment of this Agreement with respect to the First Closing Properties to AMB Institutional Alliance Fund III, LLC, a Delaware limited liability company), and (b) such assignee(s) shall be an "Approved Assignee(s)", which, for purposes hereof, shall be any entity that shall be owned or controlled by, or under common control with, Purchaser; provided, however, that no such assignment shall relieve Purchaser of any of its obligations under this Agreement; provided, further that Purchaser can assign all or a part of this Agreement to one or more Approved Assignees. 12.18 Purchaser and Seller have entered into a certain Letter of Intent dated as of August 15, 2003 (the "LOI"). Notwithstanding anything to the contrary contained herein or in the LOI, (a) this Agreement shall supercede the LOI, (b) from and after the Effective Date, the LOI shall be null and void and of no further force or effect and (c) in the event of any conflict between any term, provision or condition contained herein and any term, provision or condition contained in the LOI, the terms, provisions and conditions of this Agreement shall govern and control. 12.19 Except with respect to any Properties that Purchaser has elected not to acquire pursuant to the provisions of Paragraph 4.1, 5.1 and Article 10 hereunder, Seller agrees not to market or show any of the Properties to any other prospective purchasers during the term of this Agreement. 12.20 Purchaser and Seller each agree that the terms of this transaction, the identities of Purchaser and Seller, and all information made available by one party to the other or in any way relating to the other party's interest in this transaction, shall be maintained in strict confidence and no disclosure of such information will be made, whether or not the transaction contemplated by this Agreement shall close, except to such attorneys, accountants, investment advisors, lenders and others as are reasonably required to evaluate and consummate the transaction or as required by law. Purchaser and Seller each further agree and covenant as follows: (1) Neither Purchaser nor Seller shall disclose or authorize the disclosure of the terms of this Agreement or any instruments, documents, or assignments delivered in connection with this Agreement, or the identity of the other party to this Agreement in any public statement, news release, or other announcement or publication. (2) Nothing in this paragraph shall prevent either Purchaser or Seller from disclosing or accessing any information otherwise deemed confidential under this paragraph (i) in connection with that party's enforcement of its rights hereunder; (ii) pursuant to any legal requirement, any statutory reporting requirement or any accounting or auditing disclosure requirement; (iii) in connection with 56 performance by either party of its obligations under this Agreement (including, but not limited to, the delivery and recordation of instruments, notices or other documents required hereunder); or (iv) to potential investors, participants or assignees in or of the transaction contemplated by this Agreement or such party's rights therein. Notwithstanding anything to the contrary provided in this Subparagraph 12.20 (but subject to the provisions of Paragraph 12.20(4)), Purchaser shall be permitted to make such disclosures regarding the Property and the subject transaction as are reasonably determined to be required by law and/or as are similar or consistent with Purchaser's general public disclosure policy, including disclosures made by Purchaser in its quarterly supplemental analyst disclosure packages, and including disclosures that are necessary or appropriate in connection with Purchaser's securities filings, which may include the filing of this Agreement with the SEC. (3) If this Agreement is terminated with respect to any or all of the Properties, Purchaser shall destroy or return to Seller all materials received by Purchaser from Seller with respect to such Properties as are affected by such termination of this Agreement. (4) Notwithstanding anything to the contrary contained in this Paragraph 12.20, Purchaser shall have the sole right to determine the timing and content of the initial public announcement of the Strategic Alliance and each new Project (as such terms are defined in the Strategic Alliance Agreement), subject to IAC's consent to the content thereof (which shall not be unreasonably withheld); thereafter, either Owner (as defined in the Strategic Alliance Agreement) shall have the right to publicize the Strategic Alliance and such Project subject to the other Owner's consent (which shall not be unreasonably withheld). Notwithstanding the foregoing, Purchaser shall be permitted to make such disclosures regarding the Strategic Alliance and each Project as are similar or consistent with Purchaser's general public disclosure policy, including disclosures made by Purchaser in its quarterly supplemental analyst disclosure packages; provided, however, that in no event shall Purchaser make a public announcement of Verizon's (as defined in the Strategic Alliance Agreement) involvement in the Strategic Alliance unless, prior to such public announcement of Verizon's involvement, Purchaser determines in good faith that such public announcement of Verizon's involvement may be required by applicable laws and regulations and Purchaser provides written notice to Verizon at least two (2) business days prior to any such public announcement, which notice shall include the specific language that Purchaser proposes to include in such public announcement regarding Verizon's involvement. Purchaser shall consider in good faith any suggested revisions to such language provided by Verizon, which must be provided to Purchaser within two (2) business days after delivery of a notice to Verizon pursuant to Section 7.2 of the Strategic Alliance Agreement. In any event Purchaser may, without providing prior notice to Verizon, make a public announcement that IAC includes a pension fund affiliated with a "publicly held corporation," a "Fortune 500 company" or other similar designation. 12.21 If, within two years following the applicable Closing Date, it becomes reasonably necessary to do so in order to comply with applicable securities laws or the rules or regulations of the Securities and Exchange Commission, Purchaser shall have the right, to the extent reasonably necessary, to inspect the books and records of Seller relating to the operation of the applicable Property for the period of three (3) years preceding the Closing Date. Purchaser shall give reasonable prior written notice to Seller when Purchaser wishes to exercise its right to inspect such books and records. Such inspection shall take place at the offices of Seller's investment advisors, property manager or other location as Seller shall reasonably designate during normal business hours and on a date and at a time reasonably convenient to Seller and Purchaser. The provisions of this Subparagraph 12.22 shall 57 survive the Closing. 12.22 This Agreement is intended for the sole benefit of the parties hereto and their successors and assigns and shall not be for the benefit of any other party. 58 IN WITNESS WHEREOF, the parties have executed and delivered this Agreement as of the date first above written.
