Purchaser shall be entitled to object to any title matters shown in the Title Documents, in its sole discretion, by a written notice of objections delivered to Seller on or before the expiration of the Due Diligence Period. Purchaser shall notify Seller before the expiration of the Due Diligence Period which title exceptions (excluding survey matters), if any, will not be accepted by Purchaser (the “Title Notice”). If Purchaser fails to notify Seller in writing of its disapproval of any exceptions before the expiration of the Due Diligence Period, Purchaser shall be deemed to have approved the condition of title to the Real Property. If Purchaser notifies Seller in writing that Purchaser objects to any exceptions to title, Seller shall have three (3) Business Days after receipt of the Title Notice to notify Purchaser of either of the following: (a) that Seller will remove such objectionable exceptions from title on or before the Closing; or (b) that Seller elects not to cause such exceptions to be removed. If Seller fails to notify Purchaser within such three (3) Business Day period, then Seller shall be deemed to have made an election under the foregoing clause (a).

any liens or encumbrances that secure obligations for borrowed money and any exceptions or encumbrances to title which are created by or through Seller after the Effective Date) disclosed in the Title Commitment constituting a lien against the Real Property are to be satisfied by Seller before Closing other than Taxes that are not yet due and payable, and Seller shall, at Seller’s sole cost and expense, cause each Property to be vested in the respective Property Entity to the satisfaction of the Title Company so that the Title Company will insure that such Property Entity has fee title to the respective Real Property. With respect to any other objections, Seller will reasonably cooperate with Purchaser in curing such objections. The procurement by Seller of a commitment for the issuance of the respective Title Policies (as defined in Section 5.2(i) hereof) or an endorsement thereto insuring Purchaser, in a manner acceptable to Purchaser, against any title exception which was disapproved pursuant to this Section 3.3 shall be deemed a cure by Seller of such disapproval. If Seller gives Purchaser notice under clause (b) above, Purchaser shall have three (3) Business Days after the date of such notice in which to notify Seller that Purchaser will nevertheless proceed with the purchase in accordance with the provisions of this Agreement and take title to the Property subject to such exceptions, or that Purchaser will terminate this Agreement and receive a refund of the Xxxxxxx Money. If after the expiration of the Due Diligence Period the Title Company revises either Title Commitment or any of the UCC Commitments, or the surveyor revises either Survey, to add or modify exceptions, or to add or modify the conditions to obtaining any endorsement requested by Purchaser during the Due Diligence Period, then Purchaser may terminate this Agreement and receive a refund of the Xxxxxxx Money if the provision for their removal or modification satisfactory to Purchaser is not made. In such case, the respective Closing Date shall be extended for up to ten (10) days in order for Purchaser and Seller to determine if such exception can be resolved and to give Purchaser the opportunity to terminate this Agreement and receive a refund of the Xxxxxxx Money if the exception is not removed.

Subject only to obtaining certain internal approvals on or before the expiration of the Due Diligence Period, Purchaser has the full right and authority and has obtained any and all consents required to enter into this Agreement and the Subject Leases and to consummate or cause to be consummated the transactions contemplated hereby. This Agreement has been, and all of the documents to be delivered by Purchaser at the Closing, including the Subject Leases, will be, authorized and properly executed and constitutes, or will constitute, as appropriate, the valid and binding obligation of Purchaser, enforceable in accordance with their terms.

          (b) Conflicts and Pending Action. There is no agreement to which Purchaser is a party or to Purchaser’s Knowledge binding on Purchaser which is in conflict with this Agreement.

     8.3. Survival of Representations and Warranties. The representations and warranties set forth in this Article 8 are made as of the Effective Date and are remade as of the respective Closing Date, and such representations and warranties (and any representations and warranties in any other documents delivered to Purchaser pursuant to the provisions of this Agreement) shall not be deemed to be merged into or waived by the instruments of Closing. Seller’s representations and warranties with respect to each Property and each Closing shall survive the respective Closing Date for a period of twelve (12) months from such date with respect to Xxxxxxxx 0.0(x), (x), (x), (x), (x), (x), (x), (x), (x) and (w), for period of two (2) years from such date with respect to Sections 8.1(c), (d), (e), (f), (j), (k), (o), (r), (t), (u), (v) and (w), and for a period of 120 days after the expiration of the applicable statute of limitation with respect to Section 8.1(q) (the “Survival Period”). No claim for a breach of any of Seller’s representations and warranties, or the failure or default of a covenant or agreement of Seller, shall be actionable or payable unless (a) the breach in question results from or is based on a condition, state of facts, or other matter that was not disclosed on or before the respective Closing Date to Purchaser by or on behalf of Seller in writing or not disclosed in the Pertinent Information or on or before the respective Closing Date was not within Purchaser’s Knowledge, (b) the valid claims for all such breaches collectively aggregate more than Two Hundred Fifty Thousand Dollars ($250,000.00), in which event the full amount of such claims shall be actionable, and (c) written notice containing a description of the specific nature of such breach shall have been given by Purchaser to Seller before the expiration of the respective Survival Period and an action shall have been commenced by Purchaser against Seller within fourteen (14) months after the respective Closing. Seller shall neither knowingly nor intentionally perform any act, or permit any Property Entity to perform any act, that could cause any said representations and warranties to become untrue. Seller shall promptly notify Tenant as soon as it discovers that any representation or warranty hereunder has become untrue. Notwithstanding anything contained in this Agreement to the contrary:

          (i) If, prior to Closing, Purchaser knows that (1) any of Seller’s representations and warranties are not true or correct in any material respect as of the Effective Date, or as of the Closing Date (in each case, an “Incorrect Seller Representation”), or (2) that Seller has failed to perform any material covenant and material agreement herein contained (an “Unperformed Seller Covenant”), then within five (5) Business Days after Purchaser acquires Purchaser’s Knowledge of such Incorrect Seller Representation or such Unperformed Seller Covenant, as the case may be, Purchaser shall give Seller written notice describing the same (the “Purchaser Note”), and Seller shall have five (5) Business Days from the date of receipt of the Purchaser’s Notice to cure such Incorrect Seller Representation, or such Unperformed Seller Covenant, as the case may be, and, if necessary, the respective Closing Date will be extended up to five (5) Business Days in order to permit Seller to effect such cure. If Seller fails to effect such cure within the aforesaid five (5) Business Day period, then Purchaser shall have the right to (a) terminate this Agreement in accordance with the provisions of Section 5.5 hereof (including a refund of the Xxxxxxx Money and any earnings thereon, plus liquidated damages and out of pocket expenses as set forth in Section 5.5 hereof) or (b) seek specific performance in

accordance with the provisions of Section 5.5 hereof. In such case, the respective Closing Date shall be extended for up to ten (10) days to give Purchaser the opportunity to make such election.

          (ii) If prior to Closing, Purchaser knows of any Incorrect Seller Representation or Unperformed Seller Covenant and Purchaser shall nevertheless proceed to Closing notwithstanding the fact, Purchaser shall be deemed to have waived such Incorrect Seller Representation or Unperformed Seller Covenant and Purchaser shall not be entitled to commence any action against Seller after Closing due to such Incorrect Seller Representation or Unperformed Seller Covenant.

          (iii) All references in this Agreement to “Seller’s Knowledge,” “Seller’s actual knowledge,” or words of similar import shall refer only to the actual (as opposed to deemed, imputed, or constructive) present knowledge of Xxxxx X. Xxxxxxxxx, Vice President, Financial Operations, and Xxx Xxxxx, Vice President, Engineering, without inquiry. Messrs. Cappeluti and Xxxxx are the individuals most knowledgeable about the condition of the Properties. Notwithstanding any fact or circumstance to the contrary, Seller’s Knowledge shall not be construed to refer to the knowledge of any other person or entity. Messrs. Cappeluti and Xxxxx are not parties to this Agreement and under no circumstances shall either of them have personal liability whatsoever under this Agreement or with respect to the transactions contemplated hereunder.

          (iv) All references in this Agreement to “Purchaser’s Knowledge,” “Purchaser’s actual knowledge,” or words of similar import shall refer only to the actual (as opposed to deemed, imputed, or constructive) present knowledge of Xxxx X. Xxxxxxxx, without inquiry. Purchaser shall also be deemed to have actual knowledge of all matters disclosed in the Pertinent Information.

PURCHASER REPRESENTS TO SELLER THAT PURCHASER HAS CONDUCTED, OR WILL CONDUCT BEFORE CLOSING, SUCH INVESTIGATIONS OF THE PROPERTIES WITH QUALIFIED PROFESSIONALS OF ITS OWN SELECTION, INCLUDING BUT NOT LIMITED TO, THE PHYSICAL AND ENVIRONMENTAL CONDITIONS THEREOF, AS PURCHASER DEEMS NECESSARY TO SATISFY ITSELF AS TO THE CONDITION OF THE PROPERTIES AND THE EXISTENCE OR NONEXISTENCE OR CURATIVE ACTION TO BE TAKEN WITH RESPECT TO ANY HAZARDOUS SUBSTANCES ON OR DISCHARGED OR RELATED FROM THE PROPERTIES AND WILL RELY SOLELY ON SAME AND NOT ON ANY INFORMATION PROVIDED BY OR ON BEHALF OF THE SELLER OR SELLER’S AGENTS OR EMPLOYEES WITH RESPECT THERETO, OTHER THAN SUCH REPRESENTATIONS, WARRANTIES, AND COVENANTS OF SELLER AS ARE EXPRESSLY SET FORTH IN THIS AGREEMENT OR THE CLOSING AGREEMENTS.

If Seller fails to discharge or undertake to defend against such liability, upon receipt of written notice from Purchaser of such failure, Seller shall have fifteen (15) days (the “Defense Cure Period”) to cure such failure by prosecuting such a defense. If Seller fails to do so within the Defense Cure Period, then Purchaser may settle the same and Seller’s liability to Purchaser shall be conclusively established by such settlement

     9.2. Parties Bound. Neither party may assign this Agreement without the prior written consent of the other, and any such prohibited assignment shall be void; provided, however, that Purchaser may assign this Agreement without Seller’s consent to an Affiliate (including without limitation BioMed Realty Trust, Inc). Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the respective legal representatives, successors, assigns, heirs, and devisees of the parties.

     9.6. Governing Law. This Agreement shall, in all respects, be governed, construed, applied, and enforced in accordance with the law of the State of Maryland.

The Seller and Purchaser shall cooperate in preparing the form and substance of any press notices. The foregoing shall not preclude either party from discussing the substance or any relevant details of such transactions with any of its attorneys, accountants, professional consultants, lenders, partners, investors, or any prospective lender, partner or investor, as the case may be, or prevent either party hereto, from complying with laws, rules, regulations and court orders, including without limitation, governmental regulatory, disclosure, tax and reporting requirements, or from Seller making disclosures in the ordinary course of its due diligence inspections and contacts with third parties related thereto. Notwithstanding the foregoing but subject to any Confidentiality Agreement, any party to this transaction (and each employee, agent or representative of the foregoing) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the transaction and all materials of any kind (including opinions or other tax analyses) that are provided to them relating to such tax treatment and tax structure except to the extent maintaining such confidentiality is necessary to comply with any applicable federal or state securities laws.

A party’s address may be changed by written notice to the other party; provided, however, that no notice of a change of address shall be effective until actual receipt of such notice. Copies of notices are for informational purposes only, and a failure to give or receive copies of any notice shall not be deemed a failure to give notice. The attorney for a party has the authority to send notices on behalf of such party.

     9.16. Construction. The parties acknowledge that the parties and their counsel have reviewed and revised this Agreement and that the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement or any exhibits or amendments hereto.

Each of Purchaser, on one hand, and Seller, on the other hand, shall retain all books and records with respect to Taxes pertaining to the Membership Interests and the assets of the Property Entities, for a period of at least seven (7) years following the respective Closing Date. At the end of such period, each party shall provide the other with at least ten (10) days prior written notice before transferring, destroying or discarding any such books and records, during which period the party receiving such notice can elect to take possession, at its own expense, of such books and records. Purchaser, on one hand, and Seller, on the other hand, shall cooperate fully with the other in the conduct of any audit, litigation or other proceeding relating to Taxes involving the Membership

Interests and the assets of the Property Entities. Purchaser, on one hand, and Seller, on the other hand, further agree, upon request, to use their reasonable best efforts to obtain any certificate or other document from any governmental authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including, but not limited to, with respect to the transactions contemplated hereby).

          (b) Allocation of Taxes. Except as otherwise provided in Section 7.5 hereof relating to Transfer Taxes, Seller shall be responsible for and shall promptly pay when due all Taxes levied with respect to the Membership Interests and the assets of the Property Entities attributable to any Tax period ending on or before the respective Closing Date and the portion of any Straddle Period (as hereinafter defined) ending on such Closing Date (a “Pre-Closing Tax Period”).

          All Taxes levied with respect to the Membership Interests and the assets of the Property Entities for any Tax period beginning before and ending after the respective Closing Date (a “Straddle Period”) shall be apportioned between the Pre-Closing Tax Period and any Tax period beginning after such Closing Date and that portion of any Straddle Period beginning after such Closing Date (a “Post-Closing Tax Period”), as follows:

          (i) in the case of any Taxes other than Taxes based upon or related to income or receipts, the portion allocable to the Pre-Closing Tax Period shall be deemed to be the amount of such Tax for the entire Straddle Period multiplied by a fraction the numerator of which is the number of days in the Tax period ending on the respective Closing Date and the denominator of which is the number of days in the entire Straddle Period, and

          (ii) in the case of any Tax based upon or related to income or receipts, the portion allocable to the Pre-Closing Tax Period shall be deemed equal to the amount which would be payable if the relevant Straddle Period ended on the respective Closing Date.

          Upon receipt of any xxxx for such Taxes relating to the Membership Interests or the assets of the Property Entities, Purchaser, on one hand, and Seller, on the other hand, shall present a statement to the other setting forth the amount of reimbursement to which each is entitled under this Section 9.19 together with such supporting evidence as is reasonably necessary to calculate the proration amount. The proration amount shall be paid by the party owing it to the other within ten (10) days after delivery of such statement. In the event that Purchaser or Seller shall make any payment for which it is entitled to reimbursement under this Section 9.19, the applicable party shall make such reimbursement promptly but in no event later than ten (10) days after the presentation of a statement setting forth the amount of reimbursement to which the presenting party is entitled along with such supporting evidence as is reasonably necessary to calculate the amount of reimbursement. Notwithstanding the foregoing, Purchaser shall not be liable and Seller shall indemnify and hold Purchaser harmless for (i) any Taxes of Seller or the Property Entities levied with respect to the Membership Interests and the assets of the Property Entities attributable to Pre-Closing Tax Periods, or (ii) any other Taxes of Seller for any period.

          (c) Notices. Seller shall promptly notify Purchaser in writing upon receipt by Seller of notice of any pending or threatened federal, state, local or foreign Tax audits or assessments relating to the income, properties or operations of Seller that reasonably may be expected to relate to the Membership Interests or the assets or business of the Property Entities.

          (d) Characterization of Indemnification Payments. Any indemnification payments made to Purchaser or Seller pursuant to this Agreement shall constitute an adjustment of the consideration paid under this Agreement for Tax purposes and shall be treated as such by Purchaser and Seller on their Tax Returns to the extent permitted by law.

     9.20. Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, and all of such counterparts shall constitute one Agreement.

     9.23. Damages.
