Section 6.2 Title Report .

All (i) exceptions to title set forth in the Title Report and/or matters revealed by the Existing Survey, (ii) matters which are the obligations of Schwab under the Schwab Lease, (iii) documents and agreements contemplated by this Agreement to be recorded against the Real Property on or prior to the Closing Date, including, without limitation, the CREA, the CRA and the Updated Deed Notice, and (iv) title exceptions caused or created (whether directly or indirectly) by Purchaser or any Licensee Parties will be referred to herein as “ Permitted Exceptions . In no event shall any of the Permitted Exceptions constitute Title Defects (as hereinafter defined).

(b) All taxes, water rates or charges, sewer rents and special assessments, plus interest and penalties thereon, which on the Closing Date are due and payable and/or are liens against the Real Property and which the Property Owner is obligated to pay and discharge will be credited against the Purchase Price (subject to the provision for apportionment of taxes, water rates and sewer rents herein contained) and without the need for Purchaser to raise as a Title Defect.

(c) If on the Closing Date the Real Property shall be affected by any lien which, pursuant to the provisions of this Agreement, is required to be discharged or satisfied by Seller, Seller shall not be required to discharge or satisfy the same of record provided the money necessary to satisfy the lien is retained by the Title Company at Closing (with authority to pay in the event of enforcement of such lien), and the Title Company either omits the lien as an exception from the Title Policy or insures against collection thereof from or out of the Real Property and/or the Improvements, and a credit is given to Purchaser for the recording charges for a satisfaction or discharge of such lien. Seller shall have no obligation to remove any lien affecting the Real Property which is the obligation of Schwab to remove pursuant to the provisions of the Schwab Lease.

(d) No franchise, transfer, inheritance, income, corporate or other tax open, levied or imposed against Seller, the Property Owner or any former owner of the Property, that may be a lien against the Property on the Closing Date, shall be an objection to title if the Title Company insures against collection thereof from or out of the Real Property and/or the Improvements, and provided further that Seller deposits with the Title Company a sum reasonably sufficient to secure a release of the Real Property and/or Improvements from the lien

thereof (with authority to pay in the event of enforcement of such lien). If a search of title discloses judgments, bankruptcies, or other returns against other persons having names the same as or similar to that of Seller or the Property Owner, Seller will deliver (or cause the Property Owner to deliver) to the Title Company an affidavit stating that such judgments, bankruptcies or other returns do not apply to Seller or the Property Owner, as the case may be, and such search results shall not be deemed Title Defects.

(e) Notwithstanding anything to the contrary contained herein, except for Permitted Exceptions, Seller shall be obligated to cure and/or satisfy or cause to be deleted as an exception to title: (x) any standard exceptions (to the extent that the Title Company is willing to delete the same based solely upon receipt of the Survey and a customary affidavit from Seller or the Property Owner); (y) any of the following exceptions and encumbrances to the title to the Property as may be disclosed by the Title Report, all of which shall be referred to herein as “ Monetary Objections : (i) any deed of trust, mortgage, or other security title, assignment of leases, negative pledge, financing statement or similar security instrument entered into by Seller, the Property Owner or any of Seller’s Affiliates (including, without limitation, PXR) and encumbering all or any portion of the Property (and excluding any such instrument placed upon the Property against an interest of any Schwab Party and which encumbers such Schwab Party’s interest therein); (ii) mechanics liens affecting the Property and (iii) any other liens affecting the Property which can be satisfied by the payment of a specific, liquidated amount not to exceed Five Hundred Thousand and 00/100 Dollars ($500,000.00) in the aggregate. To the extent any Monetary Objection which Seller is obligated to remove has not been removed at or prior to Closing, Purchaser shall be entitled to apply a portion of the purchase proceeds reasonably necessary to effectuate such removal (or withhold such portion as may be reasonably necessary to remove such Monetary Objection) and Purchaser shall receive a credit against the Purchase Price for any such amounts so applied or withheld. Notwithstanding the foregoing to the contrary, if on the Closing Date there shall be security interests filed against the Property, such items shall not be Monetary Objections if (A) the personal property covered by such security interests are no longer in or on the Real Property and will not be conveyed as part of the Personal Property hereunder, and the Title Company either omits the lien or security interest as an exception from the Title Policy or insures against collection thereof from all of the Real Property and improvements erected thereon, or (B) such personal property is the property of any Schwab Party and Seller executes and delivers an affidavit to such effect.

If Seller elects to attempt to cure any Title Defect, the Scheduled Closing Date may be extended by written notice from Seller to Purchaser at any time on or prior to the Scheduled Closing Date, for a period up to but not to exceed sixty (60) days in the aggregate (but in no event shall Seller have the right to extend the Scheduled Closing Date beyond the Outside Closing Date), for the purpose of such removal. In the event that (i) Seller elects not to attempt to cure any such Title Defect, or (ii) Seller fails to cure any such Title Defect within the period elected by Seller but not to exceed sixty (60) days in the aggregate (but in no event shall Seller have the right to extend the Scheduled Closing Date beyond the Outside Closing Date), Seller shall so advise Purchaser and Purchaser shall have the right to terminate this Agreement and receive a refund of the Earnest Money Deposit, or to waive such Title Defect and proceed to the Closing without any reduction or abatement of the Purchase Price. Purchaser shall make such election within ten (10) days of receipt of Seller’s notice. If Purchaser elects to proceed to the Closing, any Title Defects waived by Purchaser shall be deemed Permitted Exceptions. This provision is subject in all respects to Seller’s obligations, and Purchaser’s rights, under Section 6.2(e) . In any such event of termination, Purchaser shall promptly return Purchaser’s Information to Seller, after which neither party shall have any further obligation to the other under this Agreement except for the Termination Surviving Obligations.

(b) Notwithstanding the foregoing, in the event further updates are made to the Title Report or Survey which reveal new matters which are not Permitted Exceptions and are not shown on the previous version of the Title Report or Survey, Purchaser may give Seller notice of any such new matters disclosed by such update which Purchaser deems unacceptable. Purchaser must object in writing to any such new matters, if at all, before 5:00 p.m. Eastern Standard Time on the fifth (5th) Business Day after receipt of any such updated Title Report or Survey first disclosing said new matters. In the event Purchaser so timely notices Seller, such items shall be subject to the process for Title Defects set forth above. If Purchaser fails to timely deliver such notice, all of such new matters shall be deemed Permitted Exceptions.

ARTICLE VII

INTERIM OPERATING COVENANTS AND POST-CLOSING MATTERS

Section 7.1 Interim Operating Covenants .

(a) Operations . From the Effective Date until Closing, Seller shall, and shall cause Property Owner, to continue to operate, manage and maintain the Real Property, Ground Lease, Sublease, Improvements and other Property in the ordinary course of its business and substantially in accordance with its present practice, subject to ordinary wear and tear and

damage caused by any Schwab Party and further subject to Article XI of this Agreement. In addition, from the Effective Date until Closing, unless required by any Authorities or Governmental Regulations, or the Schwab Lease, or in the case of an emergency or on account of a casualty at the Property (in which case the provisions of Section 11.1 of this Agreement shall apply), Seller shall not, and shall cause Property Owner not to, make any capital expenditure (or commitments therefor) at the Property (x) that aggregate in excess of $500,000, and (y) the payment for which shall be the obligation of Property Owner after the Closing.

(b) Compliance with Governmental Regulations/Waterfront Development Permit .

(i) From the Effective Date until Closing, Seller shall not, and shall cause Property Owner not to, knowingly take any action that would result in a failure to comply in all material respects with all Governmental Regulations applicable to the Property Ground Lease, Sublease, Schwab Lease, Seller’s LLC Interest and with any covenants, conditions, restrictions, encumbrances and other title exception documents affecting the Property, it being understood and agreed that prior to Closing, Seller will have the right to contest any such Governmental Regulations and any such title exception documents.

(ii) Purchaser acknowledges that NJDEP has issued that certain Waterfront Development Permit, issued July 1, 1999, as modified by Modification to Waterfront Development Permit #0906-92-0005.4 (Modification file #0906-92-0005.5) dated as of December 5, 2000 (the “ Waterfront Development Permit ”), a copy of which Purchaser has reviewed as part of the Documents, which grants to AFE, and its successors and assigns, the right to develop the Real Property, Plaza VIII and Plaza IX, in accordance with and pursuant to the provisions thereof. Purchaser acknowledges that the Building fully utilizes the development rights attributable to the Real Property, and that it is the intention of the parties that all remaining development rights accruing under the Waterfront Development Permit (as well as any other development rights accruing under all other of the Documents) are not being transferred to Purchaser on the Closing Date, but are instead being transferred to 8/9 Transferee as part of the Excluded Real Property. In connection therewith, it is a condition (the “ Permit Condition ”) to Closing that either (x) the Waterfront Development Permit is bifurcated by NJDEP prior to Closing such that after such bifurcation there shall be two permits, one relating to Plaza X (the “ Plaza X Bifurcated Waterfront Permit ”) and one relating to Plazas VIII and IX (the “ 8/9 Bifurcated Waterfront Permit ”), which permits must also comply with the remaining provisions of this Section 7.1(b)(ii) , or (y) 8/9 Transferee, in the 8/9 Transferee Guaranty (as hereinafter defined), (I) use commercially reasonable efforts to obtain such bifurcation following the Closing, (II) satisfy any obligations of Property Owner (as reconstituted on the Closing Date with Purchaser as the indirect or direct owner thereof) (“ Post-Transfer AFE ”) following the Closing under the Waterfront Development Permit until such time as the Waterfront Development Permit is bifurcated in accordance with the provisions of this Section 7.1(b)(ii) , including, without limitation, the completion of any traffic mitigation studies, but specifically excluding the maintenance of the Waterfront Walkway located on the Real Property, which shall from and after the Closing be maintained by Post-Transfer AFE at its sole cost and expense. If the Waterfront Development Permit is not bifurcated and 8/9 Transferee is to guaranty the

foregoing obligations, then the form of the 8/9 Transferee Guaranty shall be modified (in form reasonably satisfactory to both Purchaser and Seller) at Closing to reflect the addition of such guaranty, and provided the 8/9 Transferee Guaranty is executed at Closing, then the Permit Condition shall be deemed satisfied. If Seller and Purchaser are unable to reasonably agree upon the modifications to the 8/9 Transferee Guaranty for the performance of 8/9 Transferee’s obligations under this Section 7.1(b)(ii) , then such failure shall merely constitute the failure of a condition precedent to Purchaser’s obligation to close this transaction and shall not be deemed a breach or default on the part of Seller. The provisions of the 8/9 Transferee Guaranty with respect to the Waterfront Development Permit shall automatically terminate upon the final satisfaction of such obligations and liabilities. Seller will advise Purchaser in advance of any meetings or discussions with any applicable agency involved in the review of the bifurcation of the Waterfront Development Permit and Purchaser shall have the right to participate in any such conversations or meetings. Purchaser and Post-Transfer AFE have no obligation to seek or obtain the bifurcation of the Waterfront Development Permit from and after the Closing. In order for the Plaza X Bifurcated Waterfront Permit to comply with the provisions of this Section 7.1(b)(ii) , it shall not contain any obligation on the part of Post-Transfer AFE to undertake any traffic mitigation program or impose any new obligations or liabilities on the part of Post-Transfer AFE other than those that pertain to the Building and the Real Property (unless Purchaser consents thereto, which consent shall not be unreasonably withheld), it being acknowledged by Purchaser that the obligation to maintain the Waterfront Walkway located on the Real Property is not a new obligation or liability.

(c) Service Contracts . From the Effective Date until Closing, Seller shall not, and shall cause Property Owner to not, amend, modify or renew any existing service contracts or enter into any new service contracts unless (i) such amended, modified, renewed or new service contract will expire on or prior to the Closing Date or is terminable on not more than thirty (30) days notice without penalty or (ii) unless Purchaser consents thereto in writing, which approval will not be unreasonably withheld, conditioned or delayed. In addition to the foregoing, from the Effective Date until Closing, Seller shall provide Purchaser with notice and copies of any such amendments, modifications or renewals of any existing service contracts or any new service contracts.

(d) Notices . From the Effective Date until Closing, to the extent received by Property Owner, Seller shall, and shall cause Property Owner to, promptly deliver to Purchaser copies of written default notices, written notices of lawsuits, arbitrations, administrative proceedings and other material hearings and written notices of violations affecting the Ground Lease, the Sublease, the Schwab Lease, Seller’s LLC Interest and/or the other Property.

Seller will reasonably cooperate in any escrow arrangements in connection with any amendments and modifications to the Schwab Lease negotiated by Purchaser in accordance with this Section 7.1(e )(i). The amendment between Purchaser and Schwab which is in escrow on the date hereof is called the “ Existing Escrow Schwab Amendment ”.

Purchaser hereby consents to the recordation of the Amended Leases against the Real Property, and acknowledges that the Amended Leases constitute Permitted Exceptions.

The Existing Deed Notice reflects that contaminated historic fill exists at the Real Property, which must be contained as provided in the Existing Deed Notice and which cannot be disturbed without the prior consent of NJDEP. Prior to the commencement of the construction of the Building, AFE notified the NJDEP that it intended to disturb the two feet of clean fill acting as an “engineering control” (as that term is defined in Environmental Laws) over the historic fill at the Real Property, in connection with its construction activities. AFE also sought the consent of NJDEP to do so. As a condition to NJDEP’s consent to the construction activities and the disturbance of the engineering control, AFE agreed to record an updated Deed Notice reflecting the current site conditions after the construction activities have been completed (the “ Updated Deed Notice ”). In order to complete the foregoing, Seller entered into a Memorandum of Agreement (“ MOA ”) with the NJDEP (a copy of which has been delivered to Purchaser as part of the Documents) in order to obtain its approval to record the Updated Deed Notice in the title records of the Real Property and to request a termination of the Existing Deed Notice and Seller recorded the Updated Deed Notice and termination of Existing Deed Notice, in the title records of the Real Property in accordance with N.J.S.A. 58:10B-13.

The costs in connection with obtaining the Approvals shall be borne in the manner more particularly set forth in Section 10.5 of this Agreement. Purchaser acknowledges that a Certificate of Substantial Completion will be recorded against the Real Property and will constitute a Permitted Exception. Seller will use good faith efforts to obtain such additional consents from JCRA as Purchaser may reasonably request, but such additional consents shall not be conditions to Purchaser’s obligation to close hereunder. Without Purchaser’s prior written consent, Seller shall not, and shall cause the Property Owner not to, (a) amend or modify the Financial Agreement, except as it may be amended by the Amended Financial Agreement, or (b) negotiate, settle, compromise, or consent or agree to any change in, the Total Project Cost (as defined in the Financial Agreement) in any manner that directly or indirectly does or could increase the Total Project Cost beyond $78,674,777.

Purchaser acknowledges that the CRA will be recorded against the Real Property and constitutes a Permitted Exception.

(i) Rentals, in accordance with Section 10.4(b) below;

(iii) all real estate ad valorem and personal property taxes, including, without limitation, all PILOT Payments (as such term is defined in the Schwab Lease) sewer rents and charges and other state, country, school district, municipal and other governmental and quasi-governmental taxes and charges, due and payable by Seller, AFE, PXURA, PXR, PXLA for the calendar year in which the Closing occurs;

(vi) such other items of income and expense as are typically prorated at closing similar to the transaction contemplated by this Agreement.

Seller will be charged and credited for the amounts of all of the Proration Items relating to the period up to and including the Proration Time, and Purchaser will be charged and credited for the amounts of all of the Proration Items relating to the period after the Proration Time. The estimated Closing prorations being adjusted pursuant to this Agreement shall be set forth on a preliminary closing statement to be prepared by Seller and submitted to Purchaser two (2) days prior to the Closing Date (the “ Closing Statement ” ). The Closing Statement, once agreed upon, shall be signed by Purchaser and Seller. The prorations being adjusted pursuant to this Agreement shall be paid at Closing by Purchaser to Seller (if the prorations result in a net credit to Seller) or by Seller to Purchaser (if the prorations result in a net credit to Purchaser) by increasing or reducing the cash to be delivered by Purchaser in payment of the Purchase Price at the Closing. If the actual amounts of the Proration Items are not known as of the Closing Date,

the prorations will be made at Closing on the basis of the best evidence then available; thereafter, when actual figures are received, re-prorations will be made on the basis of the actual figures, and a final cash settlement will be made between Seller and Purchaser. No prorations will be made in relation to insurance premiums, and Seller’s insurance policies will not be assigned to Purchaser. Final readings and final billings for utilities will be made if possible as of the Closing Date, in which event no proration will be made at the Closing with respect to utility bills. Seller will be entitled to all deposits presently in effect with the utility providers, and Purchaser will be obligated to make its own arrangements for any deposits with the utility providers, but Seller will, if necessary, maintain such deposits until such time as Purchaser can post its own deposits (but in no event longer than thirty (30) days after Closing) so that such utility service will not be discontinued to the Property. No later than September 30, 2005, Seller and Purchaser will jointly and in good faith prepare a final closing statement reasonably satisfactory in form and substance to Seller and Purchaser (the “ Final Closing Statement ) setting forth the final determination of the adjustments and prorations provided for herein.

(b) Purchaser will receive a credit on the Closing Statement for the prorated amount (as of the Proration Time) of all Rental previously paid to or collected by Seller and attributable to any period following the Proration Time. After the Closing, Seller will cause to be paid or turned over to Purchaser all Rental, if any, received by Seller after Closing and attributable to any period following the Proration Time. “ Rental ” as used herein means all Rent (as such term is defined in the Schwab Lease) paid under the Schwab Lease. Rental is “ Delinquent ” when it was due prior to the Closing Date, and payment thereof has not been made on or before the Proration Time. Delinquent Rental will not be prorated. Purchaser agrees to use good faith collection procedures with respect to the collection of any Delinquent Rental, but Purchaser will have no liability for the failure to collect any such amounts and will not be required to pursue legal action to enforce collection of any such amounts owed to Seller by any tenant. All sums collected by Purchaser from and after Closing from Schwab will be applied first to current amounts owed by Schwab to Purchaser and then to delinquencies owed by Schwab to PXLA. Any sums due Seller will be promptly remitted to Seller.

(c) With respect to specific tenant billings for work orders, special items performed or provided at the request of Schwab or other specific services, which are collected by Purchaser after the Closing Date but relate to the foregoing specific services rendered by Seller prior to the Proration Time, then notwithstanding anything to the contrary contained herein, Purchaser shall cause the first amounts collected from Schwab specifically for such special services (as opposed to regular scheduled rental payments) to be paid to Seller on account thereof, so long as Seller identifies same prior to Closing.

(d) Seller shall be liable and solely responsible for the payment of all of the leasing commissions due and owing with respect to the initial term of the Schwab Lease (the “ Initial Term Schwab Commissions ”). Purchaser shall be liable and solely responsible for all leasing commissions payable under the Leasing Commission Agreements or otherwise with respect to any renewals or extensions of the Schwab Lease (the “ Renewal Term Schwab Commissions ”), as well as, subject to the provisions of Section 18.2 of this Agreement, the Work Allowance and the Additional Work Allowance (as such terms are defined in the Schwab

Lease) and all tenant improvement costs or other expenditures due with respect to any amendments, renewals and/or extensions of the Schwab Lease first arising, accruing and payable following the Closing Date, as set forth in the Schwab Lease or in documents provided to Purchaser prior to Closing and in any documents or pursuant to any agreements (whether written or oral entered into after the Closing by Purchaser or Property Owner), and all of the leasing commissions, tenant improvement costs and other expenditures due and owing with respect to Schwab’s exercise of Schwab’s Expansion Options.

(e) Prior to the Closing Date, Seller (or Property Owner) shall have pre-paid to the applicable Authority the amount of One Million Five Hundred Seventy-Six Thousand Four Hundred Nineteen and 00/100 Dollars ($1,576,419.00) (the “ PILOT Service Charge ) ” as and for the annual service charge required to be paid in connection with the PILOT. In addition, Purchaser hereby acknowledges that Property Owner has entered into the Contribution Agreement and in connection therewith, the amount of Three Hundred Ninety-Nine Thousand Seven Hundred and No/100 ($399,700.00) (the “ Contribution Amount ”) has been paid to the City. Seller will receive a credit on the Closing Statement (x) in an amount equal to fifty percent (50%) of the Contribution Amount (“ Purchaser’s Share of the Contribution Amount ”), and (y) in an amount equal to the PILOT Service Charge less that amount of the PILOT Service Charge, if any, which was amortized by Seller (and/or Property Owner) prior to the Closing Date (it being understood that the PILOT Service Charge shall be amortized on a straight-line basis commencing on the date of the first PILOT Payment made under the Financial Agreement (excluding the PILOT Service Charge for purposes of determining such first PILOT Payment)).

(f) At the Closing, Purchaser shall receive a credit against the Purchase Price in an amount calculated in accordance with Schedule 10.4(f) , pro-rated for a partial month (the “ Rent Shortfall Credit ”).

(b) Purchaser shall pay (i) the cost of the premium for its Title Policy and customary title searches, together with all costs of any additional coverage under its Title Policy

In the event that either Seller shall elect to effectuate the Closing as a “like-kind” exchange under Section 1031 of the Code, Purchaser agrees to cooperate and assist such Seller in all reasonable respects (with no adjustment to the Closing Date hereunder) in order that the exchange so qualifies as a “like-kind” exchange under Section 1031 of the Code and the Treasury Regulations promulgated, or to be promulgated, thereunder; provided , however , that Seller shall reimburse Purchaser for any reasonable out-of-pocket attorneys’ fees (other than incidental, de minimis expenses and attorneys’ fees).

Purchaser will have the option to terminate this Agreement upon notice to Seller given not later than fifteen (15) days after receipt of Seller’s notice.

REMEDIES

Section 13.1 Default by Seller .

(a) In the event the Closing and the transactions contemplated hereby do not occur as herein provided by reason of any default of Seller under this Agreement, Purchaser may, as Purchaser’s sole and exclusive remedy, elect by notice to Seller within ten (10) Business Days following the Scheduled Closing Date, either of the following: (i) to terminate this Agreement, in which event Purchaser will receive from the Escrow Agent the Earnest Money Deposit, and thereafter Seller and Purchaser will have no further rights or obligations under this Agreement, except with respect to the Termination Surviving Obligations; or (ii) seek to enforce specific performance of Seller’s obligation to execute the documents required to convey Seller’s LLC Interest to Purchaser, it being understood and agreed that the remedy of specific performance shall not be available to enforce any other obligation of Seller hereunder. Other than as expressly set forth in Section 13.1(b) below, Purchaser expressly waives its rights to seek damages in the event that the Closing does not occur by reason of Seller’s default hereunder. Purchaser shall be deemed to have elected to terminate this Agreement and receive back the Earnest Money Deposit if Purchaser fails to file suit for specific performance against Seller in a court having jurisdiction in the county and state in which the Property is located, on or before ninety (90) days following the Scheduled Closing Date. Notwithstanding the foregoing as to the Termination Surviving Obligations, nothing contained in this Section 13.1 will limit Purchaser’s remedies at law, in equity or as herein provided in pursuing remedies of a breach by Seller of any of the Termination Surviving Obligations. Purchaser specifically waives its rights to seek any punitive, speculative, or consequential damages.

(b) Notwithstanding Section 13.1(a) above, if Purchaser terminates this Agreement by reason of Seller’s bad faith, willful default under this Agreement, then, in addition to the return of the Earnest Money Deposit, Purchaser shall be entitled to be reimbursed for Purchaser’s actual out-of-pocket costs related to this transaction, including, without limitation, reasonable attorneys’ and third party fees and reasonable expenses and reasonable due diligence expenses with respect to the purchase of the Property, the negotiation of this Agreement (and ancillary agreements) and obtaining the Title Report and any survey of the Property.

Section 13.2 Default by Purchaser . In the event the Closing and the consummation of the transactions contemplated herein do not occur as provided herein by reason of any default of Purchaser, Purchaser and Seller agree it would be impractical and extremely difficult to fix the damages which Seller may suffer. In such event, Escrow Agent shall pay the Earnest Money Deposit to each of Harsimus (or its designee) and Columbia (or its designee) by separate Federal Reserve wire transfers of immediately available funds to the account designated by each of them, the portion of the Earnest Money Deposit to which each of them is entitled, as set forth in a writing executed by Harsimus and Columbia and which shall be furnished to Escrow Agent, and Purchaser and Seller hereby agree that (a) an amount equal to the Earnest Money Deposit is a reasonable estimate of the total net detriment Seller would suffer in the event Purchaser defaults and fails to complete the purchase of the Property, and (b) such amount will be the full, agreed and liquidated damages for Purchaser’s default and failure to complete the purchase of Seller’s LLC Interest, and will be Seller’s sole and exclusive remedy (whether at law or in equity) for any default of Purchaser resulting in the failure of consummation of the Closing, whereupon this Agreement will terminate and Seller and Purchaser will have no further rights or obligations hereunder, except with respect to the Termination Surviving Obligations. The payment of such amount as liquidated damages is not intended as a forfeiture or penalty but is intended to constitute liquidated damages to Seller. Notwithstanding the foregoing, as to the Termination Surviving Obligations, nothing contained herein will limit Seller’s remedies at law, in equity or as herein provided in the event of a breach by Purchaser of any of the Termination Surviving Obligations. Seller specifically waives its rights to seek any punitive, speculative, or consequential damages.

ESCROW AGENT

Section 16.1 Escrow .

(a) Escrow Agent will hold the Earnest Money Deposit in escrow in an interest-bearing account of the type generally used by Escrow Agent for the holding of escrow funds until the earlier of (i) the Closing, or (ii) the termination of this Agreement in accordance with any right hereunder. The Earnest Money Deposit shall be non-refundable to Purchaser, except as otherwise set forth herein, and shall be credited against the Purchase Price at the Closing. All interest earned on the Earnest Money Deposit shall be paid to the party entitled to the Earnest Money Deposit. In the event the Closing occurs, the Earnest Money Deposit will be released to Seller, and Purchaser shall receive a credit against the Purchase Price in the amount of the Earnest Money Deposit. In all other instances, Escrow Agent shall not release the Earnest Money Deposit to either party until Escrow Agent has been requested by Seller or Purchaser to release the Earnest Money Deposit as follows: (i) if requested by Seller, then upon Seller’s written demand therefore stating that Purchaser defaulted in the performance of Purchaser’s obligations to close under this Agreement and the facts and circumstances forming the basis of such default and (ii) if requested by Purchaser, then upon Purchaser’s written demand therefore, stating that Seller defaulted in the performance of Seller’s obligations to close under this Agreement and the facts and circumstances forming the basis of such default; provided, that, in neither case shall Escrow Agent release the Earnest Money Deposit until five (5) Business Days following Escrow Agent’s delivery of such written demand to the non-requesting party; provided, further, that if during such five (5) Business Days period, the non-requesting party shall have delivered to Escrow Agent a written dispute to the release of the Earnest Money Deposit, Escrow Agent shall not release the Earnest Money Deposit unless it receives further written direction signed by Seller and Purchaser.

Harsimus represents that its tax identification number, for purposes of reporting the interest earnings, is 22-3666122, and Columbia represents that its tax identification number, for purposes of reporting interest earnings, is 22-3571776.

(b) Escrow Agent shall not be liable to any party for any act or omission, except for bad faith, gross negligence or willful misconduct, and the parties agree to indemnify Escrow Agent and hold Escrow Agent harmless from any and all claims, damages, losses or expenses arising in connection herewith.

“ Escrowed Funds ”), Escrow Agent shall not be bound to release and deliver the Escrowed Funds to either party but may either (i) continue to hold the Escrowed Funds until otherwise directed in a writing signed by all parties hereto or (ii) deposit the Escrowed Funds with the clerk of any court of competent jurisdiction. Upon such deposit, Escrow Agent will be released from all duties and responsibilities hereunder.

(c) Escrow Agent shall not be required to defend any legal proceeding which may be instituted against it with respect to the Escrowed Funds, the Property or the subject matter of this Agreement unless requested to do so by Purchaser or Seller and is indemnified to its satisfaction against the cost and expense of such defense. Escrow Agent shall not be required to institute legal proceedings of any kind and shall have no responsibility for the genuineness or validity of any document or other item deposited with it or the collectibility of any check delivered in connection with this Agreement. Escrow Agent shall be fully protected in acting in accordance with any written instructions given to it hereunder and believed by it to have been signed by the proper parties.

Section 17.16 Cooperation .

(a) Purchaser acknowledges that Seller and/or any one or more of its Affiliates may be required by the Securities and Exchange Commission to file audited financial statements for one to three years after Closing with regard to the Property.

Seller or its Affiliate agrees to deliver to Purchaser a commercially reasonable confidentiality agreement in connection with the foregoing prior to any such access or copying.

(b)(i) Seller and only Seller shall prepare and file, or cause to be prepared and filed, all tax returns and reports that are required to be filed by or with respect to each Property Owner entity for all tax periods ending on or prior to the Closing Date and any amended tax return or report for any such tax period (any such tax return or report or amended tax return or report, a “ Pre-Closing Tax Return ”). Unless otherwise required by applicable law or contrary to the reasonable advice of Seller’s tax counsel or accountants, any Pre-Closing Tax Return shall be prepared on a basis consistent with past practice. Seller shall deliver, or cause to be delivered (the date of such delivery, the “ Delivery Date ” ), a copy of each such Pre-Closing Tax Return to the Purchaser for the Purchaser’s review. The Purchaser shall have until midnight on the tenth (10 ^th ) day following the Delivery Date of a Pre-Closing Tax Return to deliver to the Seller any proposed revisions that it may have to such return, which proposed revisions shall be in writing and shall be set forth in reasonable detail. Seller may incorporate (or cause to be incorporated) any one or more of such proposed revisions but shall be required to incorporate (or cause to be incorporated) only those proposed revisions: (i) which are not inconsistent with the past practice in filing such return, except if otherwise required by applicable law or contrary to the reasonable advice of Seller’s tax counsel or accountants; (ii) in the case of any federal income tax return, which has “substantial authority” (within the meaning of Treasury Regulations Section 1.6662-4(d)(1)) and which would replace a position for which there is no “substantial authority” (within the meaning of Treasury Regulations Section 1.6662-4(d)(1)); and (iii) in the case of any other Pre-Closing Tax Return, which are correct under applicable law and which would replace a position which is clearly erroneous; provided , however , that, notwithstanding anything herein to the contrary, Purchaser’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed) shall be required with respect to any position contained on any such Pre-Closing Tax Return which would reasonably result in an increase in liability to Purchaser post-Closing (including under the Financial Agreement or Amended Financial Agreement). Seller, and only Seller, may prepare and file or cause to be prepared and filed a Pre-Closing Tax Return, and under no circumstances may a Pre-Closing Tax Return be filed by Purchaser or any other person without Seller’s prior written consent. Seller, and only Seller, shall control (subject to Purchaser’s rights hereunder) any Audit (as defined below) in respect of any

tax period ending on or prior to the Closing Date (“ Seller Audit ”) and, in connection therewith, Seller shall keep Purchaser fully and contemporaneously apprised of all material aspects of any Seller Audit and shall promptly furnish or cause to be promptly furnished to Purchaser copies of any and all documents, reports, correspondence and other written materials pertaining to any Seller Audit. Seller shall be authorized to take, or cause to be taken (or not take, or cause not to be taken) any action with respect to any Seller Audit in its sole discretion; provided , however , that Seller shall not take or cause to be taken (or not take, or cause not to be taken) any action which would reasonably result in an increase in liability to Purchaser post-Closing (including under the Financial Agreement or Amended Financial Agreement) without Purchaser’s prior written consent (which consent shall not be unreasonably withheld conditioned or delayed). Seller, and only Seller, shall be entitled to any refund or credit (and/or benefit therefrom) resulting from the filing of any Pre-Closing Tax Return or arising from or in respect of any Seller Audit.

(ii) The Purchaser shall prepare, or cause to be prepared, and timely file, or cause to be timely filed, all tax returns and reports that are required to be filed by or with respect to each Property Owner for all tax periods beginning prior to, and ending after, the Closing Date, as well as any amended tax return or report for any such tax period (any such return and report or amended return or report, a “ Straddle Return ”). Purchaser shall deliver, or cause to be delivered a copy of each such Straddle Return to Seller for Seller’s review at least ten (10) prior to the filing thereof. Seller’s prior written consent (not to be unreasonably withheld, conditioned or delayed) shall be required with respect to any position contained on a Straddle Return which would reasonably result in an increase in liability to Seller for any pre-Closing period (including under the Financial Agreement or Amended Financial Agreement), except that no such consent shall be required if the total liability resulting from such position is allocable proportionately between Seller and Purchaser and Purchaser is liable for more than fifty percent (50%) of said liability. Unless otherwise required by applicable law, any Straddle Return shall be prepared on a basis consistent with past practice (to the extent of past practice). The Purchaser shall control (subject to Seller’s rights hereunder) and, unless the Seller consents in writing for the Purchaser to do otherwise, shall diligently pursue and defend (and shall cause a Property Owner to diligently pursue and defend) any Audit of any Straddle Period (“ Straddle Audit ”); provided, however that, without Seller’s prior written consent (which consent shall not be unreasonably withheld, conditioned or delayed), Purchaser shall not take or cause or permit to be taken (or not take, or cause or permit not to be taken) any action which could reasonably be expected to result in an increase in liability for Seller for any pre-Closing period (including under the Financial Agreement or Amended Financial Agreement), except that no such consent shall be required if the total liability resulting from such action is allocable proportionately between Seller and Purchaser and Purchaser is liable for more than fifty percent (50%) of said liability. Purchaser shall keep the Seller fully and contemporaneously apprised of all material aspects of any Straddle Audit and shall promptly furnish or cause to be promptly furnished to the Seller copies of any and all documents, reports, correspondence and other written materials pertaining to any Straddle Audit. At the reasonable request of Seller, the Purchaser shall use commercially reasonable efforts to pursue any claim for a refund or credit in respect of any taxes for any Straddle Period, either by the filing of an amended Straddle Return or during a Straddle Audit, unless Purchaser reasonably believes, and is able to establish to the reasonable satisfaction of

Seller and its tax counsel and accountants, that the total cost of pursuing such claim would exceed the amount of such refund or credit. Purchaser shall pay to Seller Seller’s proportionate share of any such refund or credit ( i.e. , the amount of such refund or credit multiplied by the fraction the numerator of which is the total number of days in the Pre-Closing Straddle Period and the denominator of which is the total number of days in such Straddle Period) and any interest thereon so obtained promptly after receipt from, or allowance thereof, by the relevant tax authority, less Seller’s proportionate share of the cost thereof. The Seller and Purchaser shall, and Purchaser shall cause any Property Owner to, fully cooperate in the obtaining of any refund or credit.

(iii) For purposes of this Section 17.16(b) , the term “ Audit ” shall mean any audit, assessment, or other examination or claim by any tax authority and any judicial, administrative or other proceeding or litigation (including any appeal of any such judicial, administrative or other proceeding or litigation), relating to taxes or tax returns or reports. For purposes of this Section 17.16(b) , the term “ Pre-Closing Straddle Period ” shall mean with respect to any Straddle Period, the portion of such Straddle Period beginning on the first day thereof and ending on an including the Closing Date. The Purchaser shall not dispose of any records or documents relevant to any taxes or Pre-Closing Returns or Straddle Returns prior to the later of six months after the expiration of the applicable limitations period on assessment with respect to any such taxes or tax returns, or the final resolution of any Seller Audit or Straddle Audit initiated prior to the expiration of the applicable limitations period.

(iv) Seller and Purchaser shall cooperate fully, to the extent reasonably requested, in connection with the filing of any tax return (e.g., Pre-Closing Tax Return or Straddle Tax Return) or the procuring or claiming of any refund or credit for any overpayment of taxes and with respect to any Audit (e.g., any Seller Audit or Straddle Audit). Such cooperation shall include, but shall not be limited to: (A) subject to any limitations set forth in this Section 17.16, the taking or making or the declining to take or make (or the causing of any Property Owner to take or make or to decline to take or make) any action, position or claim with respect to any Audit or tax return, as directed by the party authorized under Section 17.16 to prepare, file and/or control such tax return or Audit ( e.g. , with respect to Seller’s control of any Seller Audit in accordance with Section 17.16(b)(i)); (B), the prompt furnishing and/or making available by Seller, Purchaser and any Property Owner of any and all relevant records, documents, consents, certificates, workpapers and other information as may be necessary to control and defend any Audit and/or to prepare and timely file any tax return; and (C) making employees available on a mutually convenient basis to sign any tax return and/or sign-off on any Audit and to provide additional information and explanation of any material provided hereunder.

(c) For purposes of this Section 17.16, and as the context requires, any reference to “Property Owner” in this Section 17.16 shall be deemed to refer to and include any one or more of the Post-Transfer AFE entities.

Section 17.17 Exculpation . (a) If the Closing shall occur, other than expressly contained in guaranties, indemnities or agreements entered into at Closing by Seller, 8/9 Transferee and/or MCRLP or Seller’s Affiliates for the benefit of Purchaser (and/or Purchaser’s

Affiliates), Purchaser acknowledges and agrees that Purchaser shall look solely to Seller’s, AFE’s, PXURA’s, PXLA’s and PXR’s interests in the Property, the Ground Lease and the Sublease, and Seller’s LLC Interest, for the recovery of any judgment against Seller arising out of or relating to this Agreement and the transactions contemplated herein, and no other property or assets of Seller, Seller’s Affiliates or any of Seller’s and Seller’s Affiliates direct and indirect shareholders, officers, directors, partners, principals, members, employees, agents, contractors, and any successors or assigns of the foregoing (collectively with Seller, “ Seller Related Parties ”) shall be subject to levy, execution or other enforcement procedure for the satisfaction of Purchaser’s remedies under or with respect to this Agreement. Purchaser agrees to indemnify and hold the Seller Related Parties harmless from and against any and all losses, costs, damages, liens, claims, liabilities or expenses (including, but not limited to, reasonable attorneys’ fees, court costs and disbursements) (collectively, “ Losses ”) incurred by any of the Seller’s Related Parties arising from or by reason of any damage to person or property caused by Purchaser’s breach of this Section 17.17(a) .

(b) If the Closing occurs hereunder, then other than expressly contained in guaranties, indemnities or agreements entered into at Closing by Purchaser, Post-Transfer AFE, iStar or Purchaser’s Affiliates for the benefit of Seller (and/or Seller’s Affiliates), Seller acknowledges and agrees that Seller shall look solely to Purchaser’s, AFE’s, PXURA’s, PXLA’s and PXR’s interests in the Property, the Ground Lease and the Sublease, and Seller’s LLC Interest, for the recovery of any judgment against Purchaser arising out of or relating to this Agreement and the transactions contemplated herein, and no other property or assets of Purchaser, Purchaser’s Affiliates or any of Purchaser’s and Purchaser’s Affiliates direct and indirect shareholders, officers, directors, partners, principals, members, employees, agents, contractors, and any successors or assigns of the foregoing (collectively with Purchaser, “ Purchaser Related Parties ”) shall be subject to levy, execution or other enforcement procedure for the satisfaction of Seller’s remedies under or with respect to this Agreement. Seller agrees to indemnify and hold the Purchaser Related Parties harmless from and against any and all Losses incurred by any of the Purchaser’s Related Parties arising from or by reason of any damage to person or property caused by Seller’s breach of this Section 17.17(b) .

Section 17.18 Drafts Not an Offer to Enter into a Legally Binding Contract . The parties hereto agree that the submission of a draft of this Agreement by one party to another is not intended by either party to be an offer to enter into a legally binding contract with respect to the purchase and sale of Seller’s LLC Interest or the Property. The parties shall be legally bound with respect to the purchase and sale of the Seller’s LLC Interest pursuant to the terms of this Agreement only if and when the parties have been able to negotiate all of the terms and provisions of this Agreement in a manner acceptable to each of the parties in their respective sole discretion, including, without limitation, all of the exhibits hereto, and each of Seller and Purchaser have fully executed and delivered to each other a counterpart of this Agreement. Unless and until each of Seller and Purchaser have fully executed and delivered a counterpart of this Agreement to the other, neither shall have any obligation whatsoever to the other, except as set forth in the Confidentiality Agreement.

ARTICLE XX

8/9 TRANSFEREE DEBT MAINTENANCE COVENANT

Section 20.1 Maintenance Covenant . From the Closing through the second anniversary of the Closing (the “ Net Worth Survival Period ”), Seller shall cause 8/9 Transferee, and Purchaser shall cause Post-Transfer AFE, to maintain a Net Worth of not less than $10,000,000.00. Notwithstanding anything to the contrary provided herein, each of Seller and Purchaser shall have the right at any time during the Net Worth Survival Period to provide Escrow Agent with cash or a Letter of Credit in the amount of $10,000,000, in which case such

party providing the cash or Letter of Credit shall have no further obligations under this Article XX; provided, that if either party has delivered a Letter of Credit, such party shall have no further obligations as aforesaid so long as such Letter of Credit remains in effect through the end of the Net Worth Survival Period or so long as the Escrow Agent draws on any such Letter of Credit and holds cash proceeds in-lieu of such Letter of Credit. Any cash or Letter of Credit delivered to Escrow Agent shall be held by Escrow Agent pursuant to an escrow agreement in form reasonably satisfactory to the parties. If any party provides cash or a Letter of Credit hereunder, such cash or Letter of Credit (less any amounts drawn down under the escrow agreement) shall be refunded to such party at the expiration of the Net Worth Survival Period. “ Net Worth ” means (a) in the case of Post-Transfer AFE, net worth computed in accordance with generally accepted accounting principles and (b) in the case of 8/9 Transferee, the value of the Excluded Real Property and any improvements now or hereafter built thereon less any debt secured thereby. “Letter of Credit” means an irrevocable, unconditional letter of credit, in form approved by the party receiving such letter of credit (which approval shall not be unreasonably withheld, conditioned or delayed), naming Escrow Agent as beneficiary, issued by a bank organized or licensed under the laws of the United States, or any state thereof, having (i) a net worth computed in accordance with generally accepted accounting principles in excess of $1,500,000,000 and (ii) a senior unsecured debt rating of “A” or better as rated by Standard and Poors or ‘A-2’ or better as rated by Moody’s, and providing for draws by sight draft in New York or New Jersey, having a term of not less than 60 days. Seller agrees to indemnify, defend and hold harmless Purchaser, Post-Transfer AFE and the other entities constituting Property Owner (as reconstituted upon Closing) from and against any and all Losses which any such Persons may incur on account of Seller’s failure to cause 8/9 Transferee to comply with Section 20.1 . Purchaser agrees to indemnify, defend and hold harmless the Seller from and against any and all Losses which any such Persons may incur on account of Purchaser’s failure to cause Post-Transfer AFE to comply with Section 20.1 .

Section 20.2 Guaranty of Maintenance . At the Closing, MCRLP shall execute a guaranty pursuant to which MCRLP agrees to guaranty Seller’s obligations under this Article XX. At the Closing, iStar shall execute a guaranty pursuant to which iStar agrees to guaranty Purchaser’s obligations under this Article XX.
