Additionally, the Property Management Agreement will include a provision that, in the event of a default by HAS (beyond any applicable notice and cure period) under the Property Management Agreement, Buyer shall be permitted to terminate the Property Management Agreement and such termination shall also serve to terminate Seller’s Right of First Refusal set forth in the HC III Deed and the HC IV Deed.

Notwithstanding any provisions in this Agreement to the contrary, if Buyer fails to object in writing to an Acceptable Estoppel Certificate executed by any tenant within five (5) business days after the date the same has been delivered to Buyer, Buyer shall be deemed to have approved the same. The provisions of this Section 4.8 shall survive the applicable Closings. Notwithstanding anything to the contrary, any failure by Seller to deliver to Buyer the Acceptable Estoppel Certificates shall not be a default under this Agreement. In the event that Seller fails to delivery the Acceptable Estoppel Certificates to Buyer on or before the date that is five (5) days prior to the expiration of the Due Diligence Period, Buyer shall have the right to elect, as its sole and exclusive remedy, to (a) terminate this Agreement by written notice to Seller prior to the expiration of the Due Diligence Period, promptly after which the Initial Deposit shall be returned to Buyer and,

thereafter, the parties shall have no further rights or obligations hereunder except for obligations which expressly survive the termination of this Agreement, or (b) waive such requirement.

In addition, the transfer of the land or a subsequent change in the use of the land may result in the imposition of an additional tax plus interest as a penalty for the transfer or the change in the use of the land.

General Provisions.

Seller’s Warranties Deemed Modified. To the extent that Buyer knows or is deemed to know prior to the expiration of the Due Diligence Period that Seller’s Warranties are inaccurate, untrue or incorrect in any way, such representations and warranties shall be deemed modified to reflect Buyer’s knowledge or deemed knowledge, as the case may be.

Breach of Seller’s Warranties prior to the HC III Closing.

If at or prior to the HC III Closing, any Buyer’s Representative obtains actual knowledge that any of Seller’s Warranties are untrue, inaccurate or incorrect in any material respect, Buyer shall give Seller written notice thereof within five (5) business days of obtaining such knowledge (but, in any event, prior to the HC III Closing). If at or prior to the HC III Closing, Seller obtains actual knowledge that any of Seller’s Warranties are untrue, inaccurate or incorrect in any material respect, Seller shall give Buyer written notice thereof within five (5) business days of obtaining such knowledge (but, in any event, prior to the HC III Closing). In either such event, Seller shall have the right to cure such misrepresentation or breach.

If any misrepresentation or breach of any of Seller’s Warranties is first discovered by Buyer after the expiration of the Due Diligence Period but prior to HC III Closing and Seller either does not elect to or is not able to so cure any such misrepresentation or breach, then Buyer, as its sole and exclusive remedy for any and all such misrepresentations or breaches, shall have the following rights:

If any of Seller’s Warranties are, in the aggregate, untrue, inaccurate or incorrect in any material respect, then Buyer may elect either (A) to waive such misrepresentations or breaches and consummate the HC III portion of the Transactions without any reduction of or credit against the HC III Purchase Price, or (B) to terminate this Agreement by written notice given to Seller prior to or on the HC III Closing Date, in which event this Agreement shall be terminated, the Deposit shall be returned to Buyer and, thereafter, neither party shall have any further rights or obligations hereunder except as provided in any section hereof that by its terms expressly provides that it survives any termination of this Agreement.

If any of Seller’s Warranties are untrue, inaccurate or incorrect but are not, in the aggregate, untrue, inaccurate or incorrect in any material respect, Buyer shall be deemed to waive such misrepresentation or breach of warranty, and Buyer shall be required to consummate the HC III portion of the Transactions

without any reduction of or credit against the HC III Purchase Price.

The untruth, inaccuracy or incorrectness of Seller’s Warranties shall be deemed material for purposes of this Agreement only if Buyer’s aggregate damages resulting from the untruth, inaccuracy or incorrectness of Seller’s Warranties are reasonably estimated to exceed One Hundred Thousand and No/100 Dollars ($100,000.00).

Breach of Seller’s Warranties prior to the HC IV Closing.

If, after the HC III Closing, but at or prior to the HC IV Closing, any Buyer’s Representative obtains actual knowledge that any of Seller’s Warranties are untrue, inaccurate or incorrect in any material respect, Buyer shall give Seller written notice thereof within five (5) business days of obtaining such knowledge (but, in any event, prior to the HC IV Closing). If, after the HC III Closing, but at or prior to the HC IV Closing, Seller obtains actual knowledge that any of Seller’s Warranties are untrue, inaccurate or incorrect in any material respect, Seller shall give Buyer written notice thereof within five (5) business days of obtaining such knowledge (but, in any event, prior to the HC IV Closing). In either such event, Seller shall have the right to cure such misrepresentation or breach.

If any misrepresentation or breach of any of Seller’s Warranties is first discovered by Buyer after the HC III Closing but prior to HC IV Closing and Seller either does not elect to or is not able to so cure any such misrepresentation or breach, then Buyer, as its sole and exclusive remedy for any and all such misrepresentations or breaches, shall have the following rights:

If any of Seller’s Warranties are, in the aggregate, untrue, inaccurate or incorrect in any material respect, then Buyer may elect either (A) to waive such misrepresentations or breaches and consummate the HC IV portion of the Transactions without any reduction of or credit against the HC IV Purchase Price, or (B) to terminate this Agreement by written notice given to Seller prior to or on the HC IV Closing Date, in which event this Agreement shall be terminated, the Deposit shall be returned to Buyer and, thereafter, neither party shall have any further rights or obligations hereunder except as provided in any section hereof that by its terms expressly provides that it survives any termination of this Agreement.

If any of Seller’s Warranties are untrue, inaccurate or incorrect but are not, in the aggregate, untrue, inaccurate or incorrect in any material respect, Buyer shall be deemed to waive such misrepresentation or breach of warranty, and Buyer shall be required to consummate the HC IV portion of the Transactions

without any reduction of or credit against the HC IV Purchase Price.

Survival; Limitation on Seller’s Liability. Seller’s Warranties related to the HC III Property shall survive the HC III Closing and not be merged therein for a period of one (1) year and Seller shall only be liable to Buyer hereunder for a breach of a Seller’s Warranty related to the HC III Property with respect to which a claim is made by Buyer against Seller on or before the date that is one (1) year after the date of the HC III Closing. Seller’s Warranties related to the HC IV Property shall survive the HC IV Closing and not be merged therein for a period of one (1) year and Seller shall only be liable to Buyer hereunder for a breach of a Seller’s Warranty related to the HC IV Property with respect to which a claim is made by Buyer against Seller on or before the date that is one (1) year after the date of the HC IV Closing. Anything in this Agreement to the contrary notwithstanding, the maximum aggregate liability of Seller for breaches of Seller’s Warranties shall be limited as set forth in Section 15.13 hereof. Notwithstanding the foregoing, however, if the HC III Closing occurs, Buyer hereby expressly waives, relinquishes and releases any right or remedy available to it at law, in equity, under this Agreement or otherwise to make a claim against Seller for damages that Buyer may incur, or to rescind this Agreement and the HC III portion of the Transactions, as the result of any of Seller’s Warranties related to the HC III Property being untrue, inaccurate or incorrect if (a) Buyer knew or is deemed to know that such representation or warranty was untrue, inaccurate or incorrect at the time of the HC III Closing, or (b) Buyer’s damages as a result of such representations or warranties being untrue, inaccurate or incorrect are reasonably estimated to aggregate less than One Hundred Thousand and No/100 Dollars ($100,000.00). Notwithstanding the foregoing, however, if the HC IV Closing occurs, Buyer hereby expressly waives, relinquishes and releases any right or remedy available to it at law, in equity, under this Agreement or otherwise to make a claim against Seller for damages that Buyer may incur, or to rescind this Agreement and the HC IV portion of the Transactions, as the result of any of Seller’s Warranties related to the HC IV Property being untrue, inaccurate or incorrect if (a) Buyer knew or is deemed to know that such representation or warranty was untrue, inaccurate or incorrect at the time of the HC IV Closing, or (b) Buyer’s damages as a result of such representations or warranties being untrue, inaccurate or incorrect are reasonably estimated to aggregate less than One Hundred Thousand and No/100 Dollars ($100,000.00).

Buyer’s Covenants. Buyer hereby covenants as follows:

Confidentiality. Buyer acknowledges that any information heretofore or hereafter furnished to Buyer with respect to the Property has been and will be so furnished on the condition that Buyer maintains the confidentiality thereof. Accordingly, Buyer shall hold, and shall cause Buyer’s Representatives to hold, in strict confidence, and Buyer shall not disclose, and shall prohibit Buyer’s Representatives from disclosing, to any other person without the prior written consent of Seller: (a) the terms of this Agreement, and (b) any of the information related to the Property delivered to or for the benefit of Buyer whether by any Buyer’s Representatives or by any of the Seller Parties, including, but not limited to, any information heretofore or hereafter obtained by any Buyer’s Representatives in connection with its Due Diligence. Buyer’s obligation under clause (a) of the immediately preceding sentence shall survive the Closing for a period of two (2) years. In the event the Closing does not occur or this Agreement is terminated, Buyer shall promptly return to Seller or destroy all copies of documents containing any of such information without retaining any copy thereof or extract therefrom. Seller acknowledges that Buyer is a publicly traded entity and, as such, Buyer has obligations to make certain disclosures in order to comply with applicable Laws. Notwithstanding anything to the contrary hereinabove set forth, Buyer may disclose such information (i) on a need-to-know basis to Buyer’s Representatives, its employees, members of professional firms serving it or potential lenders, (ii) as any governmental agency may require in order to comply with applicable Laws or a court order, and (iii) to the extent that such information is a matter of public record. The provisions of this Subsection 11.1.1 shall survive any termination of this Agreement for a period of two (2) years.

Buyer’s Indemnity. Buyer hereby agrees to indemnify, defend, and hold each of the Seller Parties free and harmless from and against any and all Liabilities (including reasonable attorneys’ fees, expenses and disbursements) arising out of or resulting from (a) the breach of the terms of Subsection 11.1.1 or (b) the entry on the Real Property and/or the conduct of any Due Diligence by any Buyer’s Representatives at any time prior to the HC IV Closing; provided, however, that Buyer’s obligations under this clause (b) shall not apply to the mere discovery of a pre-existing environmental or physical condition at the Property. The provisions of this section shall survive the Closings (and not be merged therein) or any termination of this Agreement.

Seller’s Covenants. Seller hereby covenants as follows:

Contracts and Leases. Without Buyer’s prior consent, which consent shall not be unreasonably withheld, conditioned or delayed, between the Effective Date hereof and the HC III Closing Date or the HC IV Closing Date, as applicable, Seller shall not extend, renew, replace or otherwise modify any Contract or Lease or enter into any new service contract, lease or agreement unless such Contract, service contract, lease or

agreement (as so extended, renewed, replaced or modified) can be terminated by the owner of the Property without penalty on not more than thirty (30) days’ notice. Seller shall furnish Buyer with a written notice of the proposed transaction which shall contain information that Seller believes is reasonably necessary to enable Buyer to make informed decisions with respect to the advisability of the proposed transaction. If Buyer fails to object in writing to the terms set forth in Seller’s notice within five (5) business days after receipt thereof, Buyer shall be deemed to have approved the proposed transaction. Buyer’s consent shall not be unreasonably withheld, conditioned or delayed with respect to any such transaction that is proposed prior to the expiration of the Due Diligence Period. Buyer, in its sole and absolute discretion, shall be entitled to grant or withhold its consent with respect to any such transaction that is proposed between the expiration of the Due Diligence Period and the HC III Closing or the HC IV Closing, as applicable.

Maintenance of Property. Except to the extent Seller is relieved of such obligations by Article 13, between the Effective Date hereof and the HC III Closing Date or the HC IV Closing Date, as applicable, Seller shall maintain and keep the Property in a manner consistent with Seller’s past practices with respect to the Property; provided, however, that, subject to Buyer’s right to terminate this Agreement prior to the expiration of the Due Diligence Period in accordance with the terms of Article 5, Buyer hereby agrees that, except for breaches of this Section 11.2.2, Buyer, shall accept the Property subject to, and Seller shall have no obligation to cure, (a) any violations of Laws, or (b) any physical conditions which would give rise to violations of Laws, whether the same now exist or arise prior to the HC III Closing or the HC IV Closing, as applicable. Between the Effective Date hereof and the HC III Closing Date or the HC IV Closing Date, as applicable, Seller will advise Buyer of any written notice Seller receives after the Effective Date hereof from any governmental authority of the violation of any Laws regulating the condition or use of the HC III Property or the HC IV Property, as applicable.

Mutual Covenants.

Publicity. Seller and Buyer each hereby covenant and agree that (a) prior to the HC IV Closing neither Seller nor Buyer shall issue any Release (as hereinafter defined) with respect to the Transactions without the prior consent of the other, except to the extent required by applicable Law, and (b) after the HC IV Closing, any Release issued by either Seller or Buyer shall be subject to the review and approval of both parties (which approval shall not be unreasonably withheld, conditioned or delayed), except to the extent required by applicable Law. Seller acknowledges that Buyer is a publicly traded entity and, as such, Buyer has obligations to make certain public statements in order to comply with applicable Laws. If either Seller or Buyer is required by applicable Law to issue a Release, such party shall, at

least two (2) business days prior to the issuance of the same, deliver a copy of the proposed Release to the other party for its review. Seller and Buyer acknowledge and agree that the delivery of the Release to the other party as required pursuant to the foregoing sentence shall not imply that the approval of the Release by the receiving party is a condition precedent to the issuance thereof. As used herein, the term “Release” shall mean any press release or public statement with respect to the Transactions or this Agreement.

Brokers. Seller and Buyer expressly acknowledge that Seller’s Broker has acted as the exclusive broker with respect to the Transactions and with respect to this Agreement. Seller shall pay any brokerage commission due to Seller’s Broker in accordance with the separate agreement between Seller and Seller’s Broker. Seller agrees to hold Buyer harmless and indemnify Buyer from and against any and all Liabilities (including reasonable attorneys’ fees, expenses and disbursements) suffered or incurred by Buyer as a result of any claims by Seller’s Broker or any other party claiming to have represented Seller as broker in connection with the Transactions. Buyer agrees to hold Seller harmless and indemnify Seller from and against any and all Liabilities (including reasonable attorneys’ fees, expenses and disbursements) suffered or incurred by Seller as a result of any claims by any party claiming to have represented Buyer as broker in connection with the Transactions.

Tax Protests; Tax Refunds and Credits. Seller shall have the right to continue and to control the progress of and to make all decisions with respect to any contest of the real estate taxes and personal property taxes for the Property due and payable during the Closing Year and all prior years. Buyer shall have the right to control the progress of and to make all decisions with respect to any tax contest of the real estate taxes and personal property taxes for the Property due and payable during all years subsequent to the Closing Year. All real estate and personal property tax refunds and credits received after Closing with respect to the Property shall be applied in the following order of priority: first, to pay the costs and expenses (including reasonable attorneys’ fees, expenses and disbursements) incurred in connection with obtaining such tax refund or credit; and second, apportioned between Buyer and Seller as follows:

with respect to any refunds or credits attributable to real estate and personal property taxes due and payable during the Closing Year (regardless of the year for which such taxes are assessed), such refunds and credits shall be apportioned between Buyer and Seller in the manner provided in Section 6.3;

with respect to any refunds or credits attributable to real estate and personal property taxes due and payable during any period prior to the

Closing Year (regardless of the year for which such taxes are assessed), Seller shall be entitled to the entire refunds and credits; and

with respect to any refunds or credits attributable to real estate and personal property taxes due and payable during any period after the Closing Year (regardless of the year for which such taxes are assessed), Buyer shall be entitled to the entire refunds and credits.

Survival. The provisions of this Section 11.3 shall survive the Closings (and not be merged therein) or earlier termination of this Agreement.

Buyer Defaults and Seller Remedies.

If, on or before the HC III Closing Date, (i) Buyer is in default of any of its obligations hereunder, or (ii) any of Buyer’s representations or warranties are, in the aggregate, untrue, inaccurate or incorrect in any material respect, or (iii) the HC III Closing otherwise fails to occur by reason of Buyer’s failure or refusal to perform its obligations hereunder in a prompt and timely manner, and any such circumstance described in any of clauses (i), (ii) or (iii) continues for ten (10) days after written notice from Seller to Buyer, which written notice shall detail such default, untruth or failure, as applicable, then Seller may elect to (a) terminate this Agreement by written notice to Buyer, promptly after which the Deposit shall be paid to Seller as liquidated damages and, thereafter, the parties shall have no further rights or obligations hereunder except for obligations which expressly survive the termination of this Agreement, or (b) waive the condition and proceed to close the HC III portion of the Transactions.

If, after the HC III Closing Date, but on or before the HC IV Closing Date, (i) Buyer is in default of any of its obligations hereunder, or (ii) any of Buyer’s representations or warranties are, in the aggregate, untrue, inaccurate or incorrect in any material respect, or (iii) the HC IV Closing otherwise fails to occur by reason of Buyer’s failure or refusal to perform its obligations hereunder in a prompt and timely manner, and any such circumstance described in any of clauses (i), (ii) or (iii) continues for ten (10) days after written notice from Seller to Buyer, which written notice shall detail such default, untruth or failure, as applicable, then Seller may elect to (a) terminate this Agreement by written notice to Buyer, promptly after which the Deposit shall be paid to Seller as liquidated damages and, thereafter, the parties shall have no further rights or obligations hereunder except for obligations which expressly survive the termination of this Agreement or which expressly survived the HC III Closing, or (b) waive the condition and proceed to close the HC IV portion of the Transactions.

Seller Defaults and Buyer Remedies.

If, on or before the HC III Closing Date, (i) Seller is in default of any of its obligations hereunder, or (ii) any of Seller’s Warranties are, in the aggregate, untrue, inaccurate or incorrect in any material respect, or (iii) the HC III Closing otherwise fails to occur by reason of Seller’s failure or refusal to perform its obligations hereunder in a prompt and timely manner, and any such circumstance described in any of clauses (i), (ii) or (iii) continues for ten (10) days after written notice from Buyer to Seller, which written notice shall detail such default, untruth or failure, as applicable, then Buyer shall have the right, to elect, as its sole and exclusive remedy, to (a) terminate this Agreement by written notice to Seller, promptly after which the Deposit shall be returned to Buyer and, thereafter, the parties shall have no further rights or obligations hereunder except for obligations which expressly survive the termination of this Agreement, or (b) waive the condition and proceed to close the HC III portion of the Transactions, or (c) seek specific performance of this Agreement by Seller. As a condition precedent to Buyer exercising any right it may have to bring an action for specific performance hereunder, Buyer must commence such an action within ninety (90) days after the occurrence of Seller’s default. Buyer agrees that its failure to timely commence such an action for specific performance within such ninety (90) day period shall be deemed a waiver by it of its right to commence an action for specific performance as well as a waiver by it of any right it may have to file or record a notice of lis pendens or notice of pendency of action or similar notice against any portion of the Property.

If, after the HC III Closing, but at or before the HC IV Closing, (i) Seller is in default of any of its obligations hereunder, or (ii) any of Seller’s Warranties are, in the aggregate, untrue, inaccurate or incorrect in any material respect, or (iii) the HC IV Closing otherwise fails to occur by reason of Seller’s failure or refusal to perform its obligations hereunder in a prompt and timely manner, and any such circumstance described in any of clauses (i), (ii) or (iii) continues for ten (10) days after written notice from Buyer to Seller, which written notice shall detail such default, untruth or failure, as applicable, then Buyer shall have the right, to elect, as its sole and exclusive remedy, to (a) terminate this Agreement by written notice to Seller, promptly after which the Deposit shall be returned to Buyer and, thereafter, the parties shall have no further rights or obligations hereunder except for obligations which expressly survive the termination of this Agreement or which expressly survived the HC III Closing, or (b) waive the condition and proceed to close the HC IV portion of the Transactions, or (c) seek specific performance of this Agreement by Seller. As a condition precedent to Buyer exercising any right it may have to bring an action for specific performance hereunder, Buyer must commence such an action within ninety (90) days after the occurrence of Seller’s default. Buyer agrees that its failure to timely commence such an action for specific performance within such ninety (90) day period shall be deemed a waiver by it of its right to commence an action for specific performance as well as a waiver by it of any right it may have to file or record a notice of lis pendens or notice of pendency of action or similar notice against any portion of the Property.

Right to Terminate. If, after the Effective Date hereof, (a) any portion of the Property is taken by condemnation or eminent domain (or is the subject of a pending taking which has not yet been consummated), or (b) any portion of the Property is damaged or destroyed (excluding routine wear and tear), Seller shall notify Buyer in writing of such fact promptly after obtaining knowledge thereof. If the Property is the subject of a Major Casualty/Condemnation that occurs after the Effective Date hereof, Buyer shall have the right to terminate this Agreement by giving written notice to Seller no later than ten (10) business days after the giving of Seller’s notice, and the applicable Closing Date shall be extended, if necessary, to provide sufficient time for Buyer to make such election. The failure by Buyer to so elect in writing to terminate this Agreement within such ten (10) business day period shall be deemed an election not to terminate this Agreement. If this Agreement is terminated pursuant to this Section 13.1, the Deposit shall be returned to Buyer and, thereafter, this Agreement shall terminate and neither party to this Agreement shall have any further rights or obligations hereunder other than any arising under any section herein which expressly provides that it shall survive the termination of this Agreement.

Allocation of Proceeds and Awards. If a condemnation or casualty occurs after the Effective Date hereof and this Agreement is not terminated as permitted pursuant to the terms of Section 13.1, then this Agreement shall remain in full force and effect, Buyer shall acquire the remainder of the Property upon the terms and conditions set forth herein and at the applicable Closing:

if the awards or proceeds, as the case may be, have been paid to Seller prior to the applicable Closing, Buyer shall receive a credit at the applicable Closing equal to (i) the amount of any such award or proceeds on account of such condemnation or casualty, plus (ii) if a casualty has occurred and such casualty is an insured casualty, an amount equal to Seller’s deductible with respect to such casualty, less (iii) an amount equal to the Seller-Allocated Amounts; and

to the extent that such award or proceeds have not been paid to Seller prior to the applicable Closing, (i) if a casualty has occurred and such casualty is an insured casualty, Buyer shall receive a credit at the applicable Closing equal to Seller’s deductible with respect to such casualty, less an amount equal to the Seller-Allocated Amounts, and (ii) Seller shall assign to Buyer at the applicable Closing (without recourse to Seller) the rights of Seller to, and Buyer shall be entitled to receive and retain, such awards or proceeds; provided, however, that within five (5) business days after receipt of such awards or proceeds, Buyer shall pay to Seller an amount equal to the Seller-Allocated Amounts not previously paid to Seller.

Insurance. Seller shall maintain the property insurance coverage currently in effect for the Property, or comparable coverage, through the earlier of any termination of this Agreement or the applicable Closing Date.

Waiver. The provisions of this Article 13 supersede the provisions of any applicable Laws with respect to the subject matter of this Article 13.

The Escrow Agent shall invest the Escrow Deposits in government insured non-interest bearing instruments reasonably satisfactory to both Buyer and Seller, shall not commingle the Escrow Deposits with any funds of the Escrow Agent or others, and shall promptly provide Buyer and Seller with confirmation of the investments made.

If the HC IV Closing occurs, the Escrow Agent shall deliver the Escrow Deposits to, or upon the instructions of, Seller on the HC IV Closing Date.

If for any reason the HC IV Closing does not occur, the Escrow Agent shall deliver the Escrow Deposits to Seller or Buyer only upon receipt of a written demand therefor from such party, subject to the following provisions of this Subsection (c). If for any reason the HC IV Closing does not occur and either party makes a written demand upon the Escrow Agent for payment of the Escrow Deposits, the Escrow Agent shall give written notice to the other party of such demand. If the Escrow Agent does not receive a written objection from the other party to the proposed payment within ten (10) days after the giving of such notice, the Escrow Agent is hereby authorized to make such payment. If the Escrow Agent does receive such written objection within such period, the Escrow Agent shall continue to hold such amount until otherwise directed by written instructions signed by Seller and Buyer or a final judgment of a court.

The parties acknowledge that the Escrow Agent is acting solely as a stakeholder at their request and for their convenience, that the Escrow Agent shall not be deemed to be the agent of either of the parties, and that the Escrow Agent shall not be liable to either of the parties for any action or omission on its part taken or made in good faith, and not in disregard of this Agreement, but shall be liable for its negligent acts and for any Liabilities (including reasonable attorneys’ fees, expenses and disbursements) incurred by Seller or Buyer resulting from the Escrow Agent’s mistake of law respecting the Escrow Agent’s scope or nature of

its duties. Seller and Buyer shall jointly and severally indemnify and hold the Escrow Agent harmless from and against all Liabilities (including reasonable attorneys’ fees, expenses and disbursements) incurred in connection with the performance of the Escrow Agent’s duties hereunder, except with respect to actions or omissions taken or made by the Escrow Agent in bad faith, in disregard of this Agreement or involving negligence on the part of the Escrow Agent.

The Escrow Agent has executed this Agreement in the place indicated on the signature page hereof in order to confirm that the Escrow Agent has received and shall hold the Escrow Deposits in escrow, and shall disburse the Escrow Deposits pursuant to the provisions of this Article 14.

Buyer’s Assignment. Buyer may assign its rights and obligations under this Agreement in whole or in part to one or more Affiliates of Buyer without the written consent of Seller. Except as otherwise provided, Buyer shall not assign this Agreement or its rights hereunder to any individual or entity without the prior written consent of Seller, which consent Seller may grant or withhold in its sole and absolute discretion, and any such assignment shall be null and void ab initio. In the event of any permitted assignment by Buyer, any assignee shall assume any and all obligations and liabilities of Buyer under this Agreement but, notwithstanding such assumption, Buyer shall continue to be liable hereunder.

Designation Agreement. Section 6045(e) of the United States Internal Revenue Code and the regulations promulgated thereunder (herein collectively called the “Reporting Requirements”) require an information return to be made to the United States Internal Revenue Service, and a statement to be furnished to Seller, in connection with the Transactions. Escrow Agent is either (x) the person responsible for closing the Transactions (as described in the Reporting Requirements) or (y) the disbursing title or escrow company that is most significant in terms of gross proceeds disbursed in connection with the Transactions (as described in the Reporting Requirements). Accordingly:

Escrow Agent is hereby designated as the “Reporting Person” (as defined in the Reporting Requirements) for the Transactions. Escrow Agent shall perform all duties that are required by the Reporting Requirements to be performed by the Reporting Person for the Transactions.

Seller and Buyer shall furnish to Escrow Agent, in a timely manner, any information requested by Escrow Agent and necessary for Escrow Agent to perform its duties as Reporting Person for the Transactions.

Each of the parties hereto shall retain this Agreement for a period of four (4) years following the calendar year during which Closing occurs.

Survival/Merger. Except for the provisions of this Agreement which are explicitly stated to survive the HC IV Closing, (a) none of the terms of this Agreement shall survive the Closing, and (b) the delivery of the HC IV Purchase Price, the HC IV Deed and the other HC IV Closing Documents and the acceptance thereof shall effect a merger, and be deemed the full performance and discharge of every obligation on the part of Buyer and Seller to be performed hereunder.

Integration; Waiver. This Agreement, together with the Exhibits hereto, embodies and constitutes the entire understanding between the parties with respect to the Transactions and all prior agreements, understandings, representations and statements, oral or written, are merged into this Agreement. Neither this Agreement nor any provision hereof may be waived, modified, amended, discharged or terminated except by an instrument signed by the party against whom the enforcement of such waiver, modification, amendment, discharge or termination is sought, and then only to the extent set forth in such instrument. No waiver by either party hereto of any failure or refusal by the other party to comply with its obligations hereunder shall be deemed a waiver of any other or subsequent failure or refusal to so comply.

Governing Law. This Agreement shall be governed by, and construed in accordance with, the law of the State in which the Property is located.

Captions Not Binding; Exhibits. The captions in this Agreement are inserted for reference only and in no way define, describe or limit the scope or intent of this Agreement or of any of the provisions hereof. All Exhibits attached hereto shall be incorporated by reference as if set out herein in full.

Binding Effect. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

Severability. If any term or provision of this Agreement or the application thereof to any persons or circumstances shall, to any extent, be invalid or unenforceable, the remainder of this Agreement or the application of such term or provision to persons or circumstances other than those as to which it is held invalid or unenforceable shall not be affected thereby,

and each term and provision of this Agreement shall be valid and enforced to the fullest extent permitted by law.

Any notice, demand or other communication required to be given or to be served upon any party hereunder shall be void and of no effect unless given in accordance with the provisions of this section.
