ARTICLE 3 DEPOSIT AND PURCHASE PRICE 3.1 ▇▇▇▇▇▇▇ Money Deposit in Escrow. Concurrent with Seller’s and Buyer’s execution and delivery of this Agreement, the parties shall establish a strict joint order escrow with Escrowee, and Buyer shall cause the ▇▇▇▇▇▇▇ Money Deposit to be deposited therein. From and after the Contract Date, the ▇▇▇▇▇▇▇ Money Deposit shall be deemed earned by Seller and shall be completely non-refundable to Buyer except as otherwise expressly provided herein. The ▇▇▇▇▇▇▇ Money Deposit (and interest thereon net of any investment charges) shall be applied against the Purchase Price at Closing, as more specifically provided in Section 3.2 below. The ▇▇▇▇▇▇▇ Money Deposit shall also secure Buyer’s obligations contained in Section 5.2; any release of the ▇▇▇▇▇▇▇ Money shall be conditioned upon Buyer paying the amounts due or having performed the obligations specified in such section. Escrowee shall be directed by the parties to invest the entire ▇▇▇▇▇▇▇ Money Deposit in an interest bearing money market account, with interest thereon being applied on account of the Purchase Price at Closing, or if Closing does not occur for any reason, then such interest shall be paid to the party entitled to the ▇▇▇▇▇▇▇ Money Deposit hereunder. The parties shall direct Escrowee to disburse the ▇▇▇▇▇▇▇ Money Deposit with interest earned thereon (net of any investment charges), to the party entitled to the same as set forth in this Agreement, or as otherwise provided in Section 3.3 below. The refund of the ▇▇▇▇▇▇▇ Money Deposit, at the discretion of Seller, may be conditioned upon the execution and delivery by Buyer to Seller of an instrument in recordable form that disclaims any and all continuing right, title and interest in and to the Property. 3.2 Purchase Price and Handling of ▇▇▇▇▇▇▇ Money Deposit. At the Closing, upon the terms and conditions set forth in this Agreement, Buyer shall pay the Purchase Price, subject to prorations and adjustments, by wire transfer of collected federal funds. The ▇▇▇▇▇▇▇ Money Deposit (and interest thereon net of any investment charges) shall be (i) paid to Seller and

applied against the Purchase Price at Closing, or (ii) disbursed in accordance with the terms of this Agreement if Closing does not occur as contemplated hereby, subject to the provisions contained in Section 3.1. 3.3 Closing Escrow. On or prior to the Closing Date, the parties shall establish a deed and money escrow with the Escrowee through which the transaction contemplated hereby shall be closed. Upon opening of said escrow, the ▇▇▇▇▇▇▇ Money Deposit (plus interest thereon net of any investment charges) shall be disbursed from the above-described strict joint order escrow with Escrowee and deposited in the deed and money escrow. The escrow instructions for the deed and money escrow shall be in the form customarily used by the Escrowee with such special provisions added thereto as may be required to conform to the provisions of this Agreement. Said deed and money escrow shall be auxiliary to this Agreement and this Agreement shall not be merged into nor in any manner superseded by said deed and money escrow. The escrow costs and fees for each of the escrow accounts described in this Article 3 shall be equally divided between Buyer and Seller. ARTICLE 4 TITLE AND SURVEY 4.1 Title. Buyer hereby acknowledges that (i) Seller has heretofore delivered to Buyer the Title Commitment, together with a copy of each recorded document raised as an exception therein, (ii) all exceptions to title referenced in the Title Commitment (other than Monetary Liens) are acceptable to Buyer and shall be deemed Permitted Title Exceptions hereunder, and (iii) except for Monetary Liens, Seller shall have no obligation to have any exceptions to title referenced in the Title Commitment removed from the Title Commitment or insured over by the Title Company. Notwithstanding the foregoing, any delinquent real property taxes, deeds of trust, mortgages and mechanic’s liens arising out of the acts of Seller, other than liens created by, through or under tenants or securing the rights of other parties under the Contracts (collectively, “Monetary Liens”), disclosed on any Title Commitment shall be automatically deemed unpermitted exceptions, and Seller shall cause all such Monetary Liens disclosed in the Title Commitment to be removed therefrom or insured over by the Title Company on or before the Closing Date. On the Closing Date, Seller shall cause the Title Company to issue the Title Policy (or “marked-up” title commitment unconditionally committing the Title Company to issue such Title Policy) to Buyer, pursuant to and in accordance with the Title Commitment, insuring, as applicable, Buyer’s fee simple title or leasehold interest in the Land and Improvements thereon as of the Closing Date, subject only to the Permitted Title Exceptions and such other exceptions as Buyer may approve (or be deemed to have approved) pursuant to this Agreement. Buyer shall have the right, at any time prior to Closing, to cause the Title Company to issue such endorsements (“Buyer Endorsements”) to the Title Policy as Buyer shall deem necessary (including, without limitation “extended coverage”), at Buyer’s sole cost and expense and without obligation on the part of Seller to obtain such Buyer Endorsements; provided that Seller shall make good faith efforts to assist Buyer in obtaining such Buyer Endorsements, provided, further, however, that (i) Seller shall have no obligation to obtain such Buyer Endorsements, to incur any additional costs in connection with procuring such Buyer Endorsements or to obtain any consents, approvals or estoppel certificates from third parties in connection with procuring such Buyer Endorsements, and (ii) Buyer’s ability or

inability to obtain such Buyer Endorsements shall not constitute a condition precedent to Buyer’s obligations under this Agreement. 4.2 Survey. Buyer hereby acknowledges that (i) Seller has heretofore delivered the Survey to Buyer, (ii) Buyer has heretofore had an opportunity to obtain, at its expense, a new or an updated survey of the Land (in any such case, an “Updated Survey”), (iii) all matters disclosed on the Survey and any Updated Survey (or which would be disclosed on any Updated Survey) are acceptable to Buyer and shall be deemed Permitted Title Exceptions hereunder, and (iv) Seller shall have no obligation to have any matters disclosed on the Survey or any Updated Survey (or which would be disclosed on any Updated Survey) removed from or insured over by the Title Company. 4.3 Tenant Estoppels. Promptly following the Contract Date, Seller shall deliver estoppel letters to JPMorgan (i.e., but not any subtenants, licensees or other occupants) as tenant under the JPMorgan Leases, in each instance conforming with the estoppel requirements of the applicable JPMorgan Lease (in each such instance, the “Required Lease Estoppel Form”). In that regard, Seller and Buyer hereby acknowledge that JPMorgan Chase Bank, National Association (“JPMorgan”) is the sole tenant at each of the ▇▇▇▇▇▇ Building and the Phoenix Building and that JPMorgan may have subtenants. Promptly after receipt from JPMorgan, Seller shall deliver such tenant’s estoppel letter to Buyer. All estoppel letters shall be dated not earlier than thirty (30) days prior to the Closing Date (provided, however, that if the initially-scheduled Closing Date set forth in this Agreement is extended for any reason [other than a Seller default hereunder, a casualty or a condemnation or pursuant to Seller’s right to extend the Closing Date under Section 4.3(b) below] then any estoppel letter which is dated within thirty (30) days of said initially-scheduled Closing Date shall be deemed to satisfy the requirements of this Section 4.3 concerning the required date of estoppel letters, and Seller shall have no obligation to cause same to be dated-down or re-executed). Buyer’s obligation to proceed to Closing shall be conditioned upon satisfaction of the following conditions, provided that Buyer may in its sole discretion elect to waive failure by Seller to satisfy any particular condition: (a) Seller shall use good faith efforts to deliver to Buyer, on or before the Closing Date, (i) the Required Lease Estoppel Form executed by JPMorgan with respect to its Lease at the ▇▇▇▇▇▇ Building (with such non-material modifications or disclosures as JPMorgan shall make thereto), and (ii) the Required Lease Estoppel Form executed by JPMorgan with respect to its Lease at the Phoenix Building (with such non-material modifications or disclosures as JPMorgan shall make thereto) (collectively, the “Estoppel Threshold”). For purposes of the preceding sentence, a “non-material” modification or disclosure shall mean a modification or disclosure which is not inconsistent with any of Seller’s representations or warranties contained in this Agreement (except to the extent that the subject of such inconsistency has been heretofore otherwise disclosed to Buyer in this Agreement, the Due Diligence Materials or otherwise) and does not allege a default. (b) If, as of the initially-scheduled Closing Date hereunder, Buyer has not received estoppel letters executed from JPMorgan with respect to its Leases at each of the ▇▇▇▇▇▇ Building and the Phoenix Building so as to satisfy the Estoppel Threshold, Seller may in its sole discretion elect, by written notice thereof delivered to Buyer on or before

said initially-scheduled Closing Date, to extend the initially-scheduled Closing Date to a date certain which is not later than May 18, 2007 in order for Seller to continue to attempt to satisfy the Estoppel Threshold. If, on or before the Closing Date (as same may be extended as described above), Seller is unable to obtain and deliver sufficient tenant estoppel letters to satisfy the Estoppel Threshold, then Seller will not be in default by reason thereof, but Buyer shall, by notice given to Seller before the Closing, elect, as its sole recourse therefor, either (i) to waive said conditions and proceed with the Closing, accepting the Property subject thereto, or (ii) to terminate this Agreement, in which event the ▇▇▇▇▇▇▇ Money Deposit shall be returned to Buyer, subject to the disbursement and payment release conditions set forth in Section 3.1, and the parties shall have no further liability or obligations to each other hereunder (other than those liabilities and obligations that expressly survive a termination of this Agreement). Buyer’s failure to elect either (i) or (ii) above, in writing to Seller, on or before the Closing Date (as same may be extended as aforesaid) shall be deemed an election of option (i) set forth in this Section 4.3. 4.4 ▇▇▇▇▇▇ Ground Lessor and Phoenix Estoppels. Promptly following the Contract Date, Seller shall deliver an estoppel letter to each of the landlords under the ▇▇▇▇▇▇ Ground Lease and the Phoenix Tunnel Lease conforming with the estoppel requirements, if any, under each such lease (in each such instance, the “Required Ground Lease Estoppel Form”). Promptly after receipt from each said landlord, Seller shall deliver such landlord’s estoppel letter to Buyer. All estoppel letters shall be dated not earlier than thirty (30) days prior to the Closing Date (provided, however, that if the initially-scheduled Closing Date set forth in this Agreement is extended for any reason [other than a Seller default hereunder, a casualty or a condemnation or pursuant to Seller’s right to extend the Closing Date under Section 4.3(b) above] then any estoppel letter which is dated within thirty (30) days of said initially-scheduled Closing Date shall be deemed to satisfy the requirements of this Section 4.4 concerning the required date of estoppel letters, and Seller shall have no obligation to cause same to be dated-down or re-executed). Buyer’s obligation to proceed to Closing shall be conditioned upon satisfaction of the following conditions, provided that Buyer may in its sole discretion elect to waive failure by Seller to satisfy any particular condition: (a) Seller shall use good faith efforts to deliver to Buyer, on or before the Closing Date, the Required Ground Lease Estoppel Form executed by the landlords under each of the ▇▇▇▇▇▇ Ground Lease and the Phoenix Tunnel Lease (each with such non-material modifications or disclosures as the applicable landlord shall make thereto) (collectively, the “Ground Lessor Estoppel Threshold”). For purposes of the preceding sentence, a “non-material” modification or disclosure shall mean a modification or disclosure which is not inconsistent with any of Seller’s representations or warranties contained in this Agreement (except to the extent such inconsistency has been heretofore otherwise disclosed to Buyer in this Agreement, the Due Diligence Materials or otherwise) and does not allege a default. (b) If Buyer has not received estoppel letters executed from each of the landlords under the ▇▇▇▇▇▇ Ground Lease and the Phoenix Tunnel Lease so as to satisfy the Estoppel Threshold, Seller may at its election in its sole discretion substitute for any unsigned landlord estoppel letters required to satisfy the Estoppel Threshold, an estoppel

certificate in the form attached hereto as Exhibit D-1 (the “Seller Ground Lessor Estoppel Certificate”), completed, executed and delivered by Seller, whereby Seller certifies the accuracy, to Seller’s knowledge (as defined below), of the information contained in the estoppel letters as submitted to such landlords, which certification shall survive the Closing for a period of six (6) months; provided, however, that Seller’s certifications under the Seller Ground Lessor Estoppel Certificate shall in no event be deemed to be a certification with respect to matters relating to the physical or environmental condition of the Property. In the event that, following the Closing Date, Seller or Buyer obtains the Required Ground Lease Estoppel Form with respect to the ▇▇▇▇▇▇ Ground Lease or the Phoenix Tunnel Lease for which Seller delivered a Seller Ground Lessor Estoppel Certificate, then to the extent that such Required Ground Lease Estoppel Form discloses matters which are consistent with those matters set forth in the applicable Seller Ground Lessor Estoppel Certificate, Seller will be automatically released from any liability or obligation under the Seller Ground Lessor Estoppel Certificate with respect to said disclosed consistent matters. If Seller is unable to obtain and deliver sufficient landlord estoppel letters (and/or in Seller’s sole discretion, Seller Ground Lease Estoppel Certificates) to satisfy the Ground Lessor Estoppel Threshold, then Seller will not be in default by reason thereof, but Buyer shall, by notice given to Seller before the Closing, elect, as its sole recourse therefor, either (i) to waive said conditions and proceed with the Closing, accepting the Property subject thereto, or (ii) to terminate this Agreement, in which event the ▇▇▇▇▇▇▇ Money Deposit shall be returned to Buyer, subject to the disbursement and payment release conditions set forth in Section 3.1, and the parties shall have no further liability or obligations to each other hereunder (other than those liabilities and obligations that expressly survive a termination of this Agreement). Buyer’s failure to elect either (i) or (ii) above, in writing to Seller, on or before the Closing Date shall be deemed an election of option (i) set forth in this Section 4.4. ARTICLE 5 DUE DILIGENCE 5.1 Due Diligence Materials. The parties hereby acknowledge that Seller has heretofore furnished to Buyer (or made available to Buyer), copies of the Due Diligence Materials, to the extent in the possession of Seller or its affiliates. Seller makes no representation or warranty concerning the accuracy or completeness of any of the Due Diligence Materials. 5.2 Inspection. Buyer hereby acknowledges that Buyer, its officers, agents and employees (collectively, “Buyer’s Representatives”) have heretofore had access to, entry upon and the opportunity to examine, inspect, measure and test the Real Property (herein collectively, the “Inspections”) including, without limitation, the opportunity to perform invasive testing of the Real Property, a Phase I environmental site assessment of the Property (the “Phase I Study”) and an engineer’s structural report respecting the Improvements (the “Structural Report”). The costs of conducting and obtaining any such Phase I Study and the Structural Report or of otherwise performing any other Inspections shall be the responsibility of Buyer. From and after the Contract Date through the Closing (or earlier termination of this Agreement), Buyer’s

Representatives may perform additional Inspections in accordance with the provisions of this Agreement, provided, however, that said access by Buyer’s Representatives to perform said Inspections shall be subject in all respects to Seller’s and the tenants’ rights under the Leases at the Real Property. Further, any such entry by Buyer’s Representatives shall be in compliance with all permits, codes, regulations, rules, laws, statutes and other requirements of any governmental body, agency or authority having jurisdiction over the Property, as well as the requirements of any Leases, ground leases and any private covenants, restrictions and easements of record. Any invasive testing of the Real Property (including the scope thereof and the identity of the Buyer’s Representatives performing such testing) shall require Seller’s consent, which consent may be withheld in Seller’s sole discretion (subject in all respects, however, to the rights of the tenants under the Leases at the Real Property to permit or consent to same). Buyer shall promptly deliver to Seller a copy of any written report or study relating to the Property prepared for Buyer by any third party consultant or other third party Buyer Representative. Any entry upon the Land or Improvements by Buyer or Buyer’s Representatives for the purpose of conducting such Inspections shall be upon not less than twenty-four (24) hours prior notice to Seller prior to any entry upon the Land or Improvements for the purpose of conducting such Inspections, and shall be subject, in any event, to prior scheduling and coordination with Seller. At Seller’s election, a representative of Seller shall be present during any entry by Buyer or Buyer’s Representatives upon the Land or Improvements to conduct the Inspections. Buyer shall not cause or permit any mechanic’s liens, materialmen’s liens or other liens to be filed against the Property as a result of the Inspections. Buyer shall furnish Seller with evidence of commercial general liability insurance having coverage limits of at least Two Million and 00/100 US Dollars ($2,000,000), together with such other insurance as Seller may reasonably require Buyer to carry against liabilities which may arise in connection with the Inspections. All Inspections shall be performed in a manner that will not disturb the ongoing operations at the Real Property, nor cause any damage, loss, disturbance to business, cost or expense to, or claims against, Seller or the Property. Prior to Closing (or earlier termination of this Agreement), Buyer shall not approach, contact or involve itself in any discussions or negotiations with any tenant of the Real Property under any Lease or with any other occupant of the Real Property, without Seller’s prior written consent (which may be withheld in Seller’s sole discretion) and without Seller or its representative being present thereat. Buyer shall in no event (i) request or initiate any inspections of the Property by any governmental or quasi-governmental entities or agencies (provided, however, that the foregoing shall not prohibit Buyer from seeking from applicable governmental or quasi-governmental entities or agencies customary zoning compliance letters), and (ii) involve itself in any discussions with governmental or quasi-governmental entities concerning the Property without Seller being present at such discussions and pre-approving (in its sole discretion) the scope and content of such discussions. Buyer shall promptly repair and restore any damage to the Property caused by the prior or any subsequent entry upon the Land or Improvements by Buyer or the other Buyer’s Representatives. Buyer shall indemnify, defend and hold harmless Seller and Seller’s officers, directors, shareholders, partners, members, managers, tenants, agents and employees (collectively, the “Seller Indemnified Parties”), from and against any and all actions, losses, costs, damages, claims, liabilities, and expenses (including litigation expenses and court costs and reasonable attorney’s fees) brought, sought or incurred by or against any of the Seller Indemnified Parties resulting from, arising out of, or in any way relating to, entry upon the Land or Improvements by Buyer or any of the other Buyer’s Representatives or otherwise in any way related to the Inspections, whether conducted prior to,

as of or subsequent to the Contract Date, or any violation of the provisions of this Section 5.2. The foregoing indemnification and repair and restoration obligations (herein collectively referred to as “Buyer’s Indemnity”) shall expressly survive the Closing or any earlier termination of this Agreement. 5.3 Due Diligence. Buyer hereby acknowledges that (i) it has heretofore had ample opportunity to review and analyze the Due Diligence Materials, the Title Commitment, the Survey, any Updated Survey, the results of the Inspections and all other matters respecting the Property, and (ii) any future Inspections Buyer may conduct are solely being permitted as an accommodation to Buyer and the results of same shall in no event be deemed to grant Buyer any further contingency under this Agreement or serve as the basis for any right of Buyer to terminate this Agreement. Buyer hereby acknowledges that it is satisfied with all matters described above in this Section 5.3 and all other matters respecting the Property and the transaction contemplated by this Agreement generally, and that, except as otherwise expressly stated in this Agreement, Buyer shall have no right to terminate this Agreement. The parties shall proceed to close the transaction contemplated by this Agreement as provided herein, and the ▇▇▇▇▇▇▇ Money Deposit shall be deemed non-refundable (except as otherwise expressly provided herein).

Seller’s liability for breaches of the representations and warranties contained in this Agreement and for other matters shall be limited as follows: (a) Generally. All representations and warranties of Seller set forth in Section 6.1 above, as well as Buyer’s right to enforce its remedies hereunder for any breach of the same, shall survive the Closing for six (6) months (i.e., meaning that Buyer must give notice in writing to Seller of such claim, in reasonable detail, prior to the expiration of said 6-month period and commence a claim therefor in a court of competent jurisdiction within thirty (30) days thereafter). In the event that Buyer has knowledge, through its due diligence investigations or otherwise, that any of the representations or warranties made by Seller under this Agreement were not true or correct when made, and if Buyer nevertheless closes the transaction contemplated by this Agreement, then Buyer shall be deemed to have waived any such representation and warranty and shall have no further claim against Seller with respect thereto. Further, Buyer shall have no recourse against Seller to enforce or seek damages (i.e., in each case, whether under Section 8.1(c) below, Section 12.2 below or otherwise) for any breach of representations and warranties unless the total damage resulting from such breaches, in the aggregate (i.e., irrespective of whether Buyer had knowledge of same before or after Closing), exceeds Two Million and 00/100 US Dollars ($2,000,000.00) (provided that once such threshold amount has been reached, Buyer shall be entitled to recourse against Seller for the dollar value of all aggregate claims, above said threshold amount), subject in any event to the other terms, conditions and limitations set forth in this Agreement. (b) Seller’s Knowledge. As used herein, the phrase “to Seller’s knowledge” and words of similar import shall mean the actual, current knowledge as of the Contract

(c) Buyer’s Knowledge. For purposes hereof, Buyer’s “knowledge” or “actual knowledge” shall be deemed to be the actual knowledge of each of ▇▇▇▇▇▇▇▇ ▇. ▇▇▇ (“Lai”) (i.e., being the President and Chief Executive Officer of Crystal River Capital, Inc. (“Crystal”), which is the parent company of Buyer), ▇▇▇▇▇ ▇▇▇▇▇ (“▇▇▇▇▇”) (i.e., being an employee of Hyperion Brookfield Asset Management, Inc. (“Hyperion”), which is the parent company of the external manager of Crystal, which in turn is the parent company of Buyer) and ▇▇▇ ▇▇▇▇▇ (“▇▇▇▇▇”) (i.e., also being an employee of Hyperion), in each instance after inquiry of those employees and consultants of Buyer, Hyperion and Crystal that have conducted the due diligence investigation on behalf of Buyer, provided that each of Lai, ▇▇▇▇▇ and ▇▇▇▇▇ shall also be deemed to have actual knowledge of all matters disclosed by the Due Diligence Materials and any other documentation of Seller which was delivered to, or make available for review by, Buyer, Hyperion or Crystal. (d) Aggregate Liability. Except for Seller’s obligations under Article 13 and Seller’s reproration obligations under Article 10 and Seller’s obligations under any Seller Ground Lessor Estoppel Certificate and without limiting Buyer’s specific performance remedy under Section 12.2, Seller’s aggregate liability to Buyer under this Agreement and under any of the other provisions contained in the documents being delivered pursuant to Section 11.2 hereof (other than any Seller Ground Lessor Estoppel Certificate) shall in no event exceed Four Million and 00/100 US Dollars ($4,000,000.00).

All representations and warranties of Buyer set forth in this Section 6.3 as well as Seller’s right to enforce its remedies hereunder for any breach of the same, shall survive the Closing for a period of six (6) months (i.e., meaning that Seller must give notice in writing to Buyer of such claim, in reasonable detail, prior to the expiration of said 6-month period and commence a claim therefor in a court of competent jurisdiction within thirty (30) days thereafter). 6.4 AS-IS. EXCEPT FOR THOSE REPRESENTATIONS AND WARRANTIES SET FORTH IN SECTION 6.1 ABOVE AND IN SECTION 13.1 BELOW, BUYER ACKNOWLEDGES THAT IT IS NOT RELYING ON ANY REPRESENTATIONS OR WARRANTIES WHATSOEVER BY SELLER OR ANY AGENT OR EMPLOYEE THEREOF REGARDING THE PROPERTY (INCLUDING, WITHOUT LIMITATION, ITS PHYSICAL CONDITION, ITS SUITABILITY FOR ANY PARTICULAR PURPOSE, ITS COMPLIANCE WITH LAWS [INCLUDING, WITHOUT LIMITATION, ENVIRONMENTAL LAWS, OR THE ABSENCE OF HAZARDOUS SUBSTANCES THEREUPON]), AND SELLER EXPRESSLY DISCLAIMS ANY AND ALL SUCH REPRESENTATIONS AND WARRANTIES, EXPRESS OR IMPLIED, EXCEPT FOR ANY LIMITED WARRANTIES CONTAINED IN SECTION 6.1 ABOVE AND IN SECTION 13.1 BELOW. EXCEPT FOR THOSE REPRESENTATIONS AND WARRANTIES SET FORTH IN SECTION 6.1 ABOVE, BUYER SHALL ACCEPT THE PROPERTY IN ITS “AS IS”, “WHERE IS”, “WITH ALL FAULTS” CONDITION, AND SELLER HEREBY DISCLAIMS ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, EXPRESS OR IMPLIED. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, SELLER MAKES NO REPRESENTATION OR WARRANTY AS TO THE TRUTH, ACCURACY OR COMPLETENESS OF ANY MATERIALS, DATA OR OTHER INFORMATION DELIVERED OR MADE AVAILABLE BY SELLER TO BUYER IN CONNECTION WITH THE TRANSACTION CONTEMPLATED HEREBY (INCLUDING, WITHOUT LIMITATION, THE DUE DILIGENCE MATERIALS).

BUYER ACKNOWLEDGES THAT IT IS A SOPHISTICATED REAL ESTATE BUYER WHO HAS HERETOFORE HAD OPEN ACCESS TO, AND SUFFICIENT TIME TO REVIEW, ALL INFORMATION, DOCUMENTS, AGREEMENTS, STUDIES AND TESTS RELATING TO THE PROPERTY THAT BUYER DEEMED NECESSARY TO REVIEW IN ITS SOLE DISCRETION, AND HAS CONDUCTED A COMPLETE AND THOROUGH INSPECTION, ANALYSIS AND EVALUATION OF THE PROPERTY, INCLUDING BUT NOT LIMITED TO ENVIRONMENTAL TESTING. BUYER HEREBY RELEASES SELLER, ITS CONSTITUENT OWNERS, AND THEIR RESPECTIVE AGENTS AND EMPLOYEES, FROM ANY AND ALL LIABILITY, RESPONSIBILITY, CLAIMS, DAMAGES, LOSSES AND EXPENSES ARISING OUT OF OR RELATED TO THE CONDITION OF THE PROPERTY OR ITS SUITABILITY FOR ANY PURPOSE, EXCEPT FOR ANY LIABILITY OF SELLER EXPRESSLY SET FORTH HEREIN. BUYER HAS UNDERTAKEN SUCH INVESTIGATION AS BUYER DEEMED NECESSARY TO MAKE BUYER FULLY AWARE OF THE CONDITION OF THE PROPERTY AS WELL AS ALL FACTS, CIRCUMSTANCES AND INFORMATION WHICH MAY AFFECT THE USE AND OPERATION OF THE PROPERTY, AND BUYER COVENANTS AND WARRANTS TO SELLER THAT BUYER HAS RELIED AND SHALL RELY, EXCEPT TO THE EXTENT OF SELLER’S REPRESENTATIONS AND WARRANTIES CONTAINED IN SECTION 6.1 ABOVE AND IN SECTION 13.1 BELOW, SOLELY ON BUYER’S OWN DUE DILIGENCE INVESTIGATION IN DETERMINING TO PURCHASE THE PROPERTY. THE PROVISIONS OF THIS SECTION 6.4 SHALL SURVIVE THE CLOSING OR EARLIER TERMINATION OF THIS AGREEMENT AND SHALL BE INCORPORATED INTO THE CLOSING DOCUMENTS TO BE DELIVERED AT CLOSING. 6.5 Release. Without limiting the provisions of Section 6.4 above, as a continuing obligation surviving the Closing and the transfer and conveyance of the Property hereunder, Buyer hereby acknowledges and agrees that, effective upon Closing, Buyer shall be deemed to have covenanted and agreed to (i) release Seller and Seller’s “Releasees” (as hereinafter defined) from and against any and all loss, damage, claim, costs and expense (including, without limitation, actual attorneys’ fees, charges and costs) and any other liability whatsoever, whether foreseen or unforeseen, arising out of or relating to the physical condition of the Property or any portion thereof (including, without limitation, the environmental condition of the Property), regardless of whether such condition arose or came into existence before, on or after the Closing Date; and (ii) defend, indemnify and hold harmless Seller and Seller’s Releasees from and against any and all loss, damage, claim, costs and expense (including, without limitation, actual attorneys’ fees, charges and costs) and any other liability whatsoever, whether foreseen or unforeseen, arising out of or relating to the physical condition of the Property or any portion thereof (including, without limitation, the environmental condition of the Property), but only to the extent such condition arose or came into existence (x) prior to the date Seller acquired title to the Property, or (y) from and after the Closing Date hereunder. Seller’s “Releasees” shall mean Seller, its members, and their respective successors and assigns (including, without limitation, an accommodation party substituted as Seller for purposes of effecting a like-kind exchange), officers, directors, managers, agents, employees, attorneys, shareholders, and the parents, subsidiaries and affiliated companies of same. Without limiting the foregoing, from and after the execution of this Agreement, the provisions of this Section 6.5 shall continue to be effective with

respect to each Seller’s Releasee irrespective of whether thereafter such Releasee assigns or has purported to assign or otherwise dispose of its interest or any portion of its interest, under this Agreement or in the Property. ARTICLE 7 SELLER’S COVENANTS; JP SUBLEASE LETTER AGREEMENT 7.1 Covenants. Seller covenants and agrees to the following: (a) Title. Except as otherwise specifically contemplated in this Agreement or as may be required by Legal Requirements, and without limiting any rights tenants may have under their Leases, from and after the Contract Date to the Closing Date, Seller shall not further encumber title to the Property in any consensual manner without the written consent of Buyer (which consent shall not be unreasonably withheld). (b) Contracts. Except as otherwise specifically contemplated in this Agreement, and without limiting any rights tenants may have under their Leases, Seller agrees not to enter into any contracts or agreements (other than Leases, which shall be governed by Section 7.1(d) below, and other than the “JP Sublease Letter Agreement” [defined below], which shall be governed by Section 7.2 below) after the date hereof, except those which are cancelable on thirty (30) days’ notice or less and without a termination payment or penalty, to which the Buyer or the Property may be or may become subject without the express written approval of Buyer (not to be unreasonably withheld). (c) Maintenance. From the Contract Date to the Closing Date, Seller shall, at its sole cost and expense, maintain or cause to be maintained the Property consistent with Seller’s current practices, and Seller shall keep and perform or cause to be performed all obligations of Seller under the ▇▇▇▇▇▇ Ground Lease, the Phoenix Tunnel Lease, the Phoenix Tunnel Sublease, the JPMorgan Leases and any other Leases entered into in accordance with the provisions of Section 7.1(d) below, the Contracts, the Licenses and Permits and the Warranties; provided that nothing in this Agreement shall require Seller to make any capital improvements or replacements to the Property following the Contract Date, except to the extent required to do so by applicable Legal Requirements. Notwithstanding the foregoing, to the extent that any of the aforesaid maintenance obligations or obligations pertaining to capital improvements or replacements required by Legal Requirements are a tenant’s obligation under its Lease, then Seller’s sole obligation hereunder shall be to use reasonable efforts to enforce the applicable Lease in order to satisfy the aforesaid obligations described in this subsection (c). (d) Leasing. (i) During the pendency of this Agreement, Seller will deliver to Buyer notice (a “Proposed Lease Transaction Notice”) of any new Leases or any renewals, expansions, or modifications of existing Leases or any express waiver of material obligations of JPMorgan under the JPMorgan Leases to which

Seller is contemplating entering into or granting (a “Proposed Lease Transaction”), which Proposed Lease Transaction Notice shall conspicuously state thereon that failure of Buyer to deliver written notice of disapproval within five (5) business days thereafter shall be deemed to be Buyer’s approval of the applicable Proposed Lease Transaction. Seller’s Proposed Lease Transaction Notice will include a description of all Tenant Inducement Costs relating to the Proposed Lease Transaction. (ii) Seller shall not enter into any Proposed Lease Transaction without Buyer’s approval, not to be unreasonably withheld, conditioned or delayed. Buyer agrees that it will promptly review any Proposed Lease Transaction within five (5) business days after receipt of the Proposed Lease Transaction Notice from Seller. A failure to provide written notice of disapproval within such five (5) business day period will be deemed to constitute approval by Buyer for all purposes, including, without limitation, approval of the Tenant Inducement Costs, all of which shall be the responsibility of Buyer. (iii) The provisions of Section 7.1(d)(i) and (ii) above shall in no event relate to the JP Sublease Letter Agreement described below. (e) Insurance. From the Contract Date to the Closing Date, Seller shall, at its sole cost and expense, maintain in full force and effect any casualty insurance policies which Seller (but not any tenant) currently carries with respect to the Property, and, in the event that Seller currently carries any such casualty insurance policies then to the extent that Seller seeks to renew same or change policies, any replacement policy shall provide substantially similar coverage (subject to customary exceptions at the time of renewal or replacement including, without limitation, terrorism exclusions, war (declared or undeclared) exclusions and the like). Upon request, Seller shall deliver to Buyer reasonable evidence of any of said renewal or replacement policies. 7.2 JP Sublease Letter Agreement. Seller and Buyer hereby acknowledge that, in addition to the JPMorgan Leases (defined above), there exist certain other Leases at each of the ▇▇▇▇▇▇ Building and the Phoenix Building which, according to the JPMorgan Leases, are the responsibility of JPMorgan by virtue of the fact that JPMorgan entered into such other Leases, as landlord, prior to the effective dates of the JPMorgan Leases (such other Leases are sometimes referred to herein as the “Other Leases”). To Seller’s knowledge, the only Other Leases in effect are those described on Exhibit H-2 to this Agreement. In connection with the foregoing, the parties hereby acknowledge that Seller is currently in the process of negotiating a letter agreement (the “JP Sublease Letter Agreement”) with JPMorgan memorializing the understanding of JPMorgan and Seller with respect to their respective obligations relating to the Other Leases; a copy of the most recent version of the JP Sublease Letter Agreement currently being negotiated is attached hereto as Exhibit P. Seller hereby agrees to use good faith, diligent efforts to cause the JP Sublease Letter Agreement to be finalized and executed by the parties thereto prior to Closing, in such form and substance as is acceptable to Seller in its sole discretion. Without limiting the foregoing, Buyer hereby acknowledges and agrees that Seller’s ability to so cause the JP Sublease Letter Agreement to be finalized and executed is not a condition to Buyer’s obligation to consummate the transaction contemplated by this Agreement

and, accordingly, in the event that, despite Seller’s good faith, diligent efforts, the JP Sublease Letter Agreement is not so finalized and executed either before or after Closing then same shall not constitute a default by Seller hereunder or entitle Buyer to terminate this Agreement. Without limiting the foregoing provisions of this Section 7.2, Seller hereby agrees to indemnify, defend and hold Buyer harmless from and against any and all claims brought by JPMorgan against Buyer on account of security deposit and rental amounts that may have been, prior to Closing, delivered to, or collected by, Seller under the Other Leases. ARTICLE 8 CONDITIONS PRECEDENT 8.1 Conditions Precedent to the Obligations of Buyer. Buyer’s obligation to acquire the Property pursuant to this Agreement shall be subject to the satisfaction, prior to the Closing Date, of all of the following conditions precedent, each of which may be waived by Buyer in its sole discretion: (a) Seller shall have performed, in all material respects, all of its covenants and obligations under this Agreement; (b) Seller shall have timely executed and delivered to Escrowee all of the items referred to in Section 11.2 hereof; and (c) All of Seller’s representations and warranties set forth in Section 6.1 of this Agreement shall be true and correct in “all material respects” (as defined below) as of the Closing Date (provided that if Seller’s representations and warranties are not so true and correct in all material respects, Seller shall have five (5) days after written notice thereof from Buyer to [at its election] take curative action such that the representations and warranties at issue are then true and correct in all material respects); provided, however, that (i) if Buyer has knowledge (as defined in Section 6.2(c)) on or before the Contract Date of matters which, if known to Seller or if notice had been received by Seller with respect thereto, would make a representation or warranty of Seller untrue, then Seller shall not be deemed in breach of any representation or warranty with respect to such matter and Seller shall not be obligated to confirm same in its certificate delivered under Section 11.2(t) below, and such matter shall not give rise to any further condition to Buyer’s obligations under this Section 8.1; and (ii) if, due to a change of facts or circumstances, a representation or warranty by Seller that was true and accurate when made on the Contract Date, becomes untrue or inaccurate as of the Closing Date, then (x) to the extent such change was not the result of a default of any of Seller’s covenants under this Agreement, such change shall not constitute a default by Seller under this Agreement or a breach of Seller’s representations or warranties hereunder and Seller shall not be obligated to confirm same in its certificate delivered under Section 11.2(t) below, and (y) if (and only if) such change of facts or circumstances results in Seller’s representations and warranties contained in this Agreement no longer being true and correct in “all material respects” and if Seller has not taken the curative action described above in this subsection (c) within the five (5) day period provided therefor, then so long as such change was not caused by Buyer’s default hereunder, Buyer shall have such

rights (as its sole recourse therefor) as described in the last sentence of this Section 8.1. For purposes of this Section 8.1(c), the term “all material respects” shall mean that any inaccuracy in such matter at issue (together with all other breaches of representations and warranties set forth in this Agreement, if any) will have an adverse monetary effect on the Property which exceeds Two Million and 00/100 Dollars ($2,000,000.00). If any of the conditions to Buyer’s obligations to acquire the Property under this Section 8.1 have not been satisfied within the time periods and in accordance with the terms set forth herein, then Buyer shall have the right, as its sole recourse, to terminate this Agreement by written notice to Seller delivered on or before the Closing Date, in which event the ▇▇▇▇▇▇▇ Money Deposit shall be returned to Buyer, subject to the disbursement and payment release conditions set forth in Section 3.1, all obligations of the parties hereto shall thereupon cease (except for those which survive the early termination of this Agreement as expressly provided herein) and this Agreement shall thereafter be of no further force and effect, unless such failure of condition constitutes a default on the part of Seller under any other provision of this Agreement, in which case the terms of Section 12.2 shall also apply. 8.2 Conditions Precedent to the Obligations of Seller. Seller’s obligation to sell, convey, assign, transfer and deliver the Property to Buyer pursuant to this Agreement shall be subject to the satisfaction, prior to the Closing Date, of all of the following conditions precedent, each of which may be waived by Seller in its sole discretion: (a) Buyer shall have performed, in all material respects, all of its covenants and obligations under this Agreement; (b) Buyer shall have tendered the Purchase Price to Escrowee pursuant to the provisions of this Agreement; (c) Buyer shall have timely executed and delivered to Escrowee all of the items referred to in Section 11.3 hereof; and (d) All of Buyer’s representations and warranties contained in Section 6.3 of this Agreement shall be true and correct as of the Closing Date. If any of the conditions to Seller’s obligations to sell the Property under this Section 8.2 have not been satisfied within the time periods and in accordance with the terms set forth herein, then Seller shall have the right, as its sole recourse, to terminate this Agreement by written notice to Buyer, in which event the ▇▇▇▇▇▇▇ Money Deposit shall be paid to Seller, all obligations of the parties hereto shall thereupon cease (except for those which survive the early termination of this Agreement as expressly set forth herein) and this Agreement shall thereafter be of no further force and effect, unless such failure of condition constitutes a default on the part of Buyer under any other provision of this Agreement, in which case the terms of Section 12.1 shall also apply.

ARTICLE 9 DESTRUCTION, DAMAGE OR CONDEMNATION 9.1 Destruction or Damage. If, subsequent to the Contract Date and on or before the Closing Date, all or any material portion of the Real Property shall be destroyed or damaged by one or more incidents of fire or other casualty, Seller shall immediately give Buyer notice of such occurrence, and Buyer shall on or before the earlier to occur of (i) fifteen (15) days after receipt of such notice and (ii) the then scheduled Closing Date, elect by written notice to Seller to (a) terminate this Agreement, in which event the ▇▇▇▇▇▇▇ Money Deposit and any interest thereon net of any investment charges shall be returned forthwith to Buyer, subject to the disbursement and payment release conditions set forth in Section 3.1, this Agreement shall be deemed null and void and neither party shall have any further rights and obligations hereunder (other than those matters which expressly survive early termination of this Agreement); or (b) proceed to close the transaction contemplated hereby as scheduled with no adjustment to the Purchase Price (provided, however, that Buyer shall have the right to participate with Seller in the adjustment and settlement of any insurance claim relating to said damage, and, to the extent the tenant(s) under the Leases at the Real Property are not entitled to the insurance proceeds, Seller shall, at Closing, (i) assign to Buyer all of Seller’s interest in any then unpaid insurance proceeds claimed with respect to said loss or damage, and (ii) pay to Buyer all insurance proceeds theretofore paid to Seller with respect to same and not theretofore used for restoration or repair, plus any deductible amount). Buyer’s failure to give notice within the time period specified above shall be deemed to be Buyer’s election of option (b) above. For purposes of this Section 9.1, damage to the Real Property shall not be deemed to be “material” under this Section 9.1 unless the cost of restoring damage to the Real Property, in the aggregate, exceeds Twelve Million and 00/100 US Dollars ($12,000,000.00); provided, however, if, in the event of a certain fire or other casualty, any Lease requires the tenant thereunder to fully repair and restore the portion of the Real Property that is destroyed or damaged by same, and such tenant does not terminate its Lease on account thereof, then for purposes of this Agreement said fire or other casualty shall in no event be deemed “material” hereunder, irrespective of whether the cost of restoring the damage to the Real Property exceeds $12,000,000. With respect to any such damage which is not material, Buyer shall have no right to terminate this Agreement provided that closing and insurance adjustment procedures described in clause (b) above shall still apply. 9.2 Condemnation. If, subsequent to the Contract Date and on or before the Closing Date, any proceeding which shall relate to the proposed taking of any material portion of the Real Property by condemnation or eminent domain is instituted or commenced, Buyer shall have the right and option to terminate this Agreement by giving Seller written notice to such effect on or before the earlier to occur of (i) fifteen (15) days after receipt of written notification of any such occurrence or occurrences and (ii) the then scheduled Closing Date. Failure to give such notice within such time shall be conclusive evidence that Buyer has waived the option to terminate by reason of the occurrence or occurrences of which it has received notice, the parties shall proceed to close the transaction contemplated hereby and, to the extent the tenant(s) under the Leases at the Real Property are not entitled to the condemnation proceeds, Buyer shall be at Closing (i) credited with any condemnation proceeds theretofore paid to Seller with respect to the taking (and not theretofore used for restoration or repair), and (ii) assigned all Seller’s right to any other proceeds therefrom. Seller agrees to furnish Buyer written notification with respect to

any such proceedings within five (5) business days after Seller’s receipt of any such notification of such proceedings. Should Buyer elect to so terminate this Agreement, the ▇▇▇▇▇▇▇ Money Deposit plus any interest thereon net of any investment charges shall be returned forthwith to Buyer, subject to the disbursement and payment release conditions set forth in Section 3.1, this Agreement shall be deemed null and void and neither party shall have any further rights and obligations hereunder (other than those matters which expressly survive early termination of this Agreement). For purposes of this Section 9.2, a taking of the Real Property shall not be deemed to be “material” under this Section 9.2 unless the value of the portion of the Real Property taken exceeds, in the aggregate, Twelve Million and 00/100 US Dollars ($12,000,000.00); provided, however, if, in the event of a certain condemnation or eminent domain proceeding, any Lease requires the tenant thereunder to fully repair and restore the portion of the Real Property affected thereby and such tenant does not terminate its Lease on account thereof, then for purposes of this Agreement, such condemnation or eminent domain proceedings shall in no event be deemed “material” hereunder, irrespective of whether the value of the Real Property taken exceeds $12,000,000. With respect to any such taking which is not material Buyer shall have no right to terminate this Agreement provided that, to the extent the tenant(s) at the Real Property are not entitled to the condemnation proceeds, Buyer shall still be (i) credited with any condemnation proceeds paid to Seller (and not theretofore used for restoration or repair) and (ii) assigned all of Seller’s right to any other proceeds therefrom. ARTICLE 10 POSSESSION, PRORATIONS AND CLOSING COSTS 10.1 Possession. Sole and exclusive possession of the Property shall be delivered to Buyer on the Closing Date, subject only to the rights of tenants and other occupants under the Leases, and the parties under any Permitted Title Exceptions, the Contracts, the ▇▇▇▇▇▇ Ground Lease, the Phoenix Tunnel Lease and the Phoenix Tunnel Sublease. 10.2 Prorations. (a) The following will be apportioned with respect to the Property as of 12:01 a.m. (local time at the Property), on the day of Closing, as if Buyer were vested with title to the Property during the entire day upon which Closing occurs: (i) Current rents collected from tenants under the Leases, and rents collected by Seller under the Phoenix Tunnel Sublease (if any), shall be prorated for the month during which the Closing occurs (the term “rents” as used in this Agreement includes all payments due and payable by tenants under the Leases); (ii) Current bills for real estate taxes and special assessments, if any, assessed against the Property (“Taxes”) for the calendar year of Closing shall be prorated on a cash basis, as opposed to an accrual basis, as follows: (A) Buyer shall receive a credit for Taxes payable in calendar year 2007, attributable to the period of Seller’s ownership of the Property in calendar year 2007, as and to the extent that Seller has not yet paid the

relevant ▇▇▇▇ therefor; and Seller shall receive a credit for Taxes paid by or on behalf of Seller in calendar year 2007 to the relevant taxing authority prior to Closing, for Taxes attributable to the period of Buyer’s ownership of the Property in calendar year 2007; (B) Subject to reconciliation as provided in subparagraph (f), below, Seller shall retain all amounts paid or payable by tenants under the Leases on account of Taxes payable during calendar year 2007 for the period prior to Closing, and Buyer shall be entitled to amounts paid by tenants under the Leases on account of Taxes payable during calendar year 2007 for the period after Closing. Notwithstanding the foregoing provisions of this subsection (ii), to the extent it is the responsibility of the tenants under the Leases to pay the Taxes directly to the applicable taxing authorities, there shall be no proration between Seller and Buyer with respect thereto. Any refund or credit attributable to Seller’s overpayment of Taxes payable in 2007 for the period prior to Closing and for previous years (collectively, the “Refund”) which is not the property of tenants under Leases is the property of Seller, and Buyer shall reasonably cooperate with Seller to obtain the Refund at Seller’s reasonable expense. Any other refund for overpayment for Taxes for any other period belongs to Buyer. (b) Payments of accounts for water, sewer, electricity, telephone and all other utilities currently in the name of Seller (or its managing agent) shall be placed in the name of Buyer on the Closing Date and Seller shall arrange for final meter readings and metered services to be conducted on the Closing Date. Seller shall be responsible to pay in full all bills for such utility charges related to any period prior to the Closing Date and Buyer shall be responsible to pay all utility charges related to any period on and subsequent to the Closing Date. With respect to utilities which are not metered, charges for such service shall be prorated as of the Closing Date, based on charges for the previous billing period, and Buyer and Seller shall receive credits or charges, as appropriate, with such amounts to be reprorated promptly after the final bills are issued. Seller shall cooperate with Buyer to effect the transfer of utility accounts from Seller to Buyer. Notwithstanding the foregoing provisions of this subsection (b), to the extent that it is the responsibility of the tenants under the Leases to pay the aforesaid utilities directly to the applicable utility providers, there shall be no proration between Seller and Buyer with respect thereto. (c) Buyer shall be entitled to a credit against the Purchase Price for sums that are due (or accrued) and unpaid as of the Closing Date under any Contracts being assumed by Buyer which are not otherwise covered by the foregoing provisions of this Section 10.2, and Seller shall be entitled to a credit to the extent that sums have been paid under any Contract, for services to be performed or goods to be delivered after the Closing Date.

(d) Seller shall be responsible for all Tenant Inducement Costs which are due and payable on or before the Closing Date under or related to the Leases in existence as of the Contract Date; Buyer shall be responsible for (and Seller shall have no responsibility for) all Tenant Inducement Costs (i) for or related to all new Leases (i.e., including, without limitation, any amendment to an existing Lease) signed after the Contract Date; and/or (ii) which are due and payable after the Closing Date for or related to the Leases in existence as of the Contract Date. (e) Unpaid and delinquent rent collected by Seller and Buyer after the Closing Date will be delivered as follows: (i) if Seller collects any unpaid or delinquent rent for the Property, Seller will, within fifteen (15) days after the receipt thereof, deliver to Buyer any such rent which Buyer is entitled to hereunder relating to the date of Closing and any period thereafter, and (ii) if Buyer collects any unpaid or delinquent rent from the Property, Buyer will, within fifteen (15) days after the receipt thereof, deliver to Seller any such rent which Seller is entitled to hereunder relating to the period prior to the date of Closing. Seller and Buyer agree that all rent received by Seller or Buyer will be applied first to rents that became due and payable after Closing, and second, to those which were due and payable prior to Closing, in reverse order of maturity. Buyer will make a good faith effort after Closing to collect all unpaid and delinquent rents in the usual course of Buyer’s operation of the Property, but Buyer will not be obligated to institute any lawsuit or other collection procedures to collect such unpaid or delinquent rents. In the event that there shall be any rents or other charges under any Leases which, although relating to a period prior to Closing, do not become due and payable until after Closing or are paid prior to Closing but are subject to adjustment after Closing (e.g., such as year end operating and common area expense reimbursements and the like), then any rents or charges of such type received by Buyer or its agents or Seller or its agents subsequent to Closing will, to the extent applicable to a period extending through the Closing, be prorated between Seller and Buyer as of Closing and Seller’s portion thereof will be remitted promptly to Seller by Buyer without reduction for any costs of collection or processing. (f) The parties shall perform a year end reconciliation of rents and operating expense contributions and any pass-throughs as required under the Leases for calendar year 2007 prior to February 15, 2008. If the annual reconciliation of Tenant/occupant rents, operating expenses and pass-throughs for the 2007 calendar year results in there being amounts due and payable by the tenants or other occupants, Buyer will collect such amounts and pay the portion of same for Seller’s period of ownership to Seller promptly upon Buyer’s receipt. If such reconciliation results in there being refunds due and payable to tenants or other occupants on account of the pass through of specifically designated expenses incurred during Seller’s period of ownership, Seller will pay to Buyer the amount of any such documented pass-through of expenses within ten (10) business days of receipt of a written request therefor from Buyer, whereupon Buyer will promptly disburse the appropriate refunds to the tenants or other occupants. There shall be no further obligation to reprorate or reconcile tenant pass-throughs after February 15, 2008 (the “Final Payment Date”).

(g) Notwithstanding anything to the contrary contained in this Agreement, rentals and other amounts under the ▇▇▇▇▇▇ Ground Lease shall be prorated as follows: (i) Fixed, minimum and base rentals, payable under the ▇▇▇▇▇▇ Ground Lease, for the month of Closing shall be prorated between Seller and Buyer on a per diem basis; (ii) Any and all real estate taxes, and ad valorem taxes, assessments, levies and charges which are the responsibility of the “Tenant” under the ▇▇▇▇▇▇ Ground Lease shall be prorated in accordance with the provisions of Section 10.2(a)(ii) above; provided, however, that to the extent that such taxes, assessments, levies and charges for which the “Tenant” under the ▇▇▇▇▇▇ Ground Lease is responsible, are paid directly to applicable taxing authority by the tenants under the Leases at the Real Property, there shall be no proration between Seller and Buyer with respect thereto. (h) All other expenses customarily prorated on the transfer of net leased properties in the areas where the Property is located shall be prorated on an accrual basis as of the Closing Date on the basis of the most recent ascertainable amounts of or other reliable information in respect to each such item of income and expense, and the net credit to Buyer or Seller shall be paid in cash or as a credit against that portion of the Purchase Price payable on the Closing Date. Any item prorated on an estimated basis on the Closing Date shall be reprorated by the parties when and as the actual amount of such item of income or expense becomes known and adjusted on or before the Final Payment Date. Any adjustment due to reproration shall be effected promptly following final determination of the amount of such item and demand by the party to whom credit is due. (i) The provisions of this Section 10.2 will survive the Closing. 10.3 Closing Costs. Seller shall be responsible for: (i) one hundred percent (100%) of all title charges and premiums attributable to the Phoenix Commitment, the Phoenix Policy (and “▇▇▇▇-up”), the ▇▇▇▇▇▇ Commitment, and the ▇▇▇▇▇▇ Policy (and “▇▇▇▇-up”) required to be delivered by Seller hereunder (i.e., specifically excluding any additional charges or premiums for Buyer Endorsements, but specifically including 100% of any additional charges or premiums for insuring or endorsing over unpermitted Monetary Liens); (ii) all charges for the Survey; (iii) fifty percent (50%) of all state, county, local and municipal transfer taxes, if any; and (v) fifty percent (50%) of all closing fees and escrow fees and costs. Buyer shall be responsible for (a) one hundred percent (100%) of all fees for any Updated Survey, all state deed fees, documentary fees, and all recording fees; (b) fifty percent (50%) of all state, county, local and municipal transfer taxes, if any; (c) fifty percent (50%) of all closing fees and escrow fees and costs; (d) 100% of the costs of all Buyer Endorsements; and (e) 100% of all costs incurred in connection with any financing obtained by Buyer (including all charges for any lender title insurance commitments or policies and closing services performed by the Title Company) and in connection with any Inspections conducted by Buyer hereunder. Buyer and Seller shall each pay the fees and expenses of their respective legal counsel incurred in connection with the transaction contemplated hereby, subject, however, to the provisions of Section 15.7 below.

ARTICLE 11 CLOSING 11.1 Time and Place. The closing of the transaction contemplated hereby (“Closing”) shall take place at the offices of Seller’s attorney (or such other place as may be mutually agreed upon by the parties) on the Closing Date. The Closing shall be effected pursuant to the escrow instructions described in Section 3.3 above. 11.2 Seller’s Deliveries. On or before the Closing Date, Seller shall deliver or cause to be delivered to Buyer or to Escrowee the following documents, each of which shall be in form and substance reasonably acceptable to Buyer: (a) The ▇▇▇▇▇▇ Deed and the Phoenix Deed; (b) Two (2) counterpart originals of each of (i) BREOF ▇▇▇▇▇▇’▇ Assignment and Assumption of Contracts substantially in the form attached as Exhibit I hereto (the “Assignment of Contracts”) and relating to those Contracts for the ▇▇▇▇▇▇ Real Property, executed by BREOF ▇▇▇▇▇▇, and (ii) BREOF Phoenix’s Assignment of Contracts relating to those Contracts for the Phoenix Real Property, executed by BREOF Phoenix; (c) Two (2) counterpart originals of each of (i) BREOF ▇▇▇▇▇▇’▇ Assignment and Assumption of the Licenses and Permits and Warranties, substantially in the form attached as Exhibit J hereto (the “Assignment of Licenses and Permits and Warranties”) and relating to those Licenses and Permits and Warranties for the ▇▇▇▇▇▇ Real Property, executed by BREOF ▇▇▇▇▇▇, and (ii) BREOF Phoenix’s Assignment of Licenses and Permits and Warranties relating to those Licenses and Permits and Warranties for the Phoenix Real Property, executed by BREOF Phoenix; (d) Each of (i) BREOF ▇▇▇▇▇▇’▇ ▇▇▇▇ of Sale substantially in the form attached as Exhibit K hereto (“▇▇▇▇ of Sale”) assigning and conveying the Tangible Personal Property and the Intangible Personal Property relating to the ▇▇▇▇▇▇ Real Property, executed by BREOF ▇▇▇▇▇▇ and (ii) BREOF Phoenix’s ▇▇▇▇ of Sale assigning and conveying the Tangible Personal Property and Intangible Personal Property relating to the Phoenix Real Property, executed by BREOF Phoenix; (e) Two (2) counterpart originals of each of (i) BREOF ▇▇▇▇▇▇’▇ Assignment and Assumption of Leases substantially in the form attached as Exhibit L hereto (the “Assignment of Leases”) relating to the JPMorgan Lease at the ▇▇▇▇▇▇ Real Property and any new Leases entered into pursuant to Section 7.1(d) above at the ▇▇▇▇▇▇ Real Property, executed by BREOF ▇▇▇▇▇▇; and (ii) BREOF Phoenix’s Assignment of Leases, relating to the JPMorgan Lease at the Phoenix Real Property, any new Leases entered into pursuant to Section 7.1(d) above at the Phoenix Real Property and the Phoenix Tunnel Sublease, executed by BREOF Phoenix;

Seller agrees to use good faith, diligent efforts to cause the Title Company, at Closing, to issue (or irrevocably commit to issue) the Title Policy, in all material respects, as required under this Agreement. If, however, the Title Company fails or refuses to issue (or irrevocably commit to issue) said Title Policy at Closing, and provided that (i) Seller

has utilized good faith, diligent efforts to cause Title Company to issue (or irrevocably commit to issue) such Title Policy, (ii) Seller has delivered all customary indemnifications and/or affidavits to the Title Company to enable the Title Company to issue (or irrevocably commit to issue) such Title Policy, (iii) the failure of the Title Company to issue (or irrevocably commit to issue) such Title Policy is not the result of any new title matter first arising from and after the date of the Title Commitment and arising from the acts or omissions of Seller in violation of the provisions of this Agreement, and (iv) the failure of the Title Company to issue (or irrevocably commit to issue) such Title Policy is not a result of any default of Seller hereunder (other than a default based on a failure of Seller to cause the Title Company to issue (or irrevocably commit to issue) such Title Policy otherwise required hereunder), then, notwithstanding anything contained in this Agreement to the contrary, the failure of the Title Company to issue (or irrevocably commit to issue) said Title Policy shall not be deemed a default by Seller hereunder, and, in lieu thereof, and as its sole recourse, Buyer may elect to either (1) terminate this Agreement, in which event the ▇▇▇▇▇▇▇ Money Deposit and any interest thereon net of investment charges shall be forthwith returned to Buyer, subject to the disbursement and payment release conditions set forth in Section 3.1, all obligations of the parties hereunder shall terminate, and this Agreement shall otherwise have no further force and effect (other than those matters which expressly survive early termination of this Agreement), or (2) proceed to close the transactions contemplated hereby in accordance with the terms of this Agreement, whereupon Buyer shall accept such form of title insurance policies, if any, as the Title Company is then prepared to issue. Buyer’s failure to make either of the two elections described in the preceding sentence on or before the Closing Date shall be deemed an election of option (2) above. ARTICLE 12 DEFAULT 12.1 Buyer Default. (a) Notwithstanding anything to the contrary contained in this Agreement, if, prior to Closing, Buyer is in default of this Agreement or in breach of any representation or warranty as and when made in this Agreement and Seller has knowledge thereof prior to Closing, then Seller shall deliver to Buyer written notice of such default or breach, which notice shall describe the nature of the default or breach and Buyer shall have a period of five (5) days to cure same (provided, however, that Buyer shall not be entitled to any such notice and opportunity to cure for any default under Articles 10, 11, 13 and Article 16). If such default or breach remains uncured beyond the five (5) day period described above, as applicable, or in the event of such default or breach where no such notice and cure period is permitted as provided above, then, except as provided below in this Section 12.1 and without limiting the other obligations and indemnities under this Agreement that expressly survive the termination of this Agreement, as Seller’s sole and exclusive remedy in lieu of all other legal or equitable remedies, Seller shall be entitled to (i) retain the ▇▇▇▇▇▇▇ Money Deposit and interest earned thereon (net of investment charges) as Seller’s liquidated damages, or (ii) waive the default at issue in writing and proceed to close the transaction contemplated by this Agreement in accordance with the other terms and provisions of this Agreement. THE PARTIES AGREE THAT IT WOULD BE IMPRACTICABLE AND EXTREMELY DIFFICULT TO ASCERTAIN

THE ACTUAL DAMAGES SUFFERED BY SELLER AS A RESULT OF BUYER’S FAILURE TO COMPLETE THE PURCHASE OF THE PROPERTY PURSUANT TO THIS AGREEMENT, AND THAT UNDER THE CIRCUMSTANCES EXISTING AS OF THE DATE OF THIS AGREEMENT, THE LIQUIDATED DAMAGES PROVIDED FOR IN THIS SECTION REPRESENT A REASONABLE ESTIMATE OF THE DAMAGES WHICH SELLER WILL INCUR AS A RESULT OF SUCH FAILURE; PROVIDED, HOWEVER, THAT THIS PROVISION SHALL NOT AFFECT SELLER’S RIGHTS AND BUYER’S INDEMNITY OBLIGATIONS UNDER SECTION 5.2 OF THIS AGREEMENT, NOR SELLER’S RIGHTS AND BUYER’S OBLIGATIONS UNDER ARTICLE 13 AND ARTICLE 16 BELOW AND UNDER THE CONFIDENTIALITY AGREEMENT. THE PARTIES ACKNOWLEDGE THAT THE PAYMENT OF SUCH LIQUIDATED DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY, BUT IS INTENDED TO CONSTITUTE LIQUIDATED DAMAGES TO SELLER. EACH PARTY HEREBY AGREES TO WAIVE ANY AND ALL RIGHTS WHATSOEVER TO CONTEST THE VALIDITY OF THE LIQUIDATED DAMAGE PROVISIONS FOR ANY REASON WHATSOEVER, INCLUDING, BUT NOT LIMITED TO, THAT SUCH PROVISION WAS UNREASONABLE UNDER CIRCUMSTANCES EXISTING AT THE TIME THIS AGREEMENT WAS MADE.

Seller and Purchaser hereby further acknowledge that, (i) it was Seller’s and Purchaser’s intention under the Sale/Purchase Agreement that, since BREOF Phoenix and BREOF Fannin were leasing the full Phoenix Property and Fannin Property, respectively, back to Seller at Closing, any then-existing leases, licenses or other occupancy agreements at the Phoenix Property and Fannin Property (including, without limitation, those described on Exhibit B-1 attached hereto (collectively, the “Phoenix Subleases”) and those described on Exhibit B-2 attached hereto (collectively, the “Fannin Subleases”)) would be thereafter deemed to be subleases under the Phoenix Master Lease or the Fannin Master Lease, respectively, (ii) it was Seller’s and Purchaser’s intention that the Phoenix Subleases and the Fannin Subleases not be assigned to Purchaser or any of its affiliates at Closing and, instead, that Seller would remain primarily and solely responsible, as landlord, under each Phoenix Sublease and Fannin Sublease, for all obligations and liabilities of the landlord thereunder, whether occurring before, as of or after Closing, and (iii) at Closing Seller and Purchaser incorrectly assigned and assumed the Phoenix Subleases and the Fannin Subleases pursuant to that certain Assignment of Leases dated as of September 27, 2006 between Seller, as assignor, and BREOF Phoenix, as assignee (the “Phoenix Assignment”; a copy of the Phoenix Assignment is attached hereto as Exhibit C-1), and that certain Assignment of Leases dated as of September 27, 2006, between Seller, as assignor, and BREOF Fannin, as assignee (the “Fannin Assignment”; a copy of the Fannin Assignment is attached hereto as Exhibit C-2).

W I T N E S S E T H: WHEREAS, on September 27, 2006, JPMorgan Chase Bank, National Association, a national banking association (“Master Tenant”) sold, conveyed and assigned its interest in the Property legally described in Exhibit A attached hereto (the “Land”) together with all buildings (“Buildings”) and improvements constructed thereon (collectively with the Land, the “Real Estate”) to Master Landlord; WHEREAS, Master Landlord then master leased the entire Real Estate back to Master Tenant pursuant to that certain JPMorgan Chase Net Lease Agreement of Lease dated as of September 27, 2006 (as amended from time to time, the “Master Lease”) between Master Landlord, as landlord, and Master Tenant, as tenant; WHEREAS, Master Tenant and Subtenant have heretofore entered into that certain [Agreement of Lease] dated as of , 200___(the “Sublease”), wherein Master Tenant leased to Subtenant a portion of Real Estate more particularly described therein (the “Premises”); and WHEREAS, the parties hereto desire, subject to the provisions set forth in this Agreement, to assure Subtenant of possession of the Premises for the entire term of the Sublease, irrespective of any default by Master Tenant under the Master Lease. NOW, THEREFORE, in consideration of the covenants and agreements contained herein, the parties covenant and agree as follows: 1. As long as no default exists after the applicable notice and grace period for the cure thereof under the Sublease as would entitle Master Tenant, as the landlord thereunder, to terminate the Sublease, Master Landlord agrees that: (a) Subtenant shall not be joined as a party defendant in any action or proceeding which may be instituted or taken by Master Landlord for the purpose of

terminating the Master Lease (or Master Tenant’s possessory rights thereunder) by reason of default by Master Tenant thereunder; and (b) Without limiting the provisions of Section 2 below, Subtenant shall not be evicted from the Premises, nor shall Subtenant’s leasehold estate under the Sublease be terminated or disturbed, nor shall any of Subtenant’s rights under the Sublease be affected in any way by reason of any default by Master Tenant under the Master Lease. 2. If, for any reason, the Master Lease is (or Master Tenant’s possessory rights thereunder are) terminated, Subtenant shall attorn to Master Landlord under all the terms, covenants and conditions of the Sublease for the balance of the term thereof, including any extension terms thereunder, with the same force and effect as if Master Landlord were the landlord under the Sublease.
