Ladies and Gentlemen:

     BioMed Realty Trust, Inc., a Maryland corporation (the “Company”), and BioMed Realty, L.P., a Maryland limited partnership (the “Operating Partnership” and together with the Company, the “Transaction Entities”), each confirms its agreement with Raymond James & Associates, Inc. (“Raymond James”) and each of the other underwriters named in Schedule I hereto (the “Underwriters”) for whom Raymond James is acting as representative (the “Representative”) with respect to the issuance and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of 5,700,000 shares (the “Firm Securities”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), and with respect to the grant by the Company to the Underwriters, acting severally and not jointly, of an option to purchase an aggregate of not more than 855,000 additional shares of Common Stock (the “Optional Securities”), subject to the terms and conditions set forth below. The Firm Securities and the Optional Securities are herein collectively called the “Offered Securities.” This agreement by and among the Company, the Operating Partnership and the Underwriters shall be referred to as this “Agreement.”

     The Company will contribute the net proceeds from each sale of the Offered Securities to the Operating Partnership and, in exchange therefor, at the Closing Date (as defined herein) of each such sale, the Operating Partnership will issue to the Company units of limited partnership interest in the Operating Partnership (“OP Units”).

     The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-137376) covering the registration of the Offered Securities under the Securities Act of 1933, as amended (the “Act”). Such registration statement became effective upon filing pursuant to Rule 462(e) of the rules and regulations of the Commission under the Act (the “Securities Act Regulations”) on September 15, 2006. Promptly after execution and delivery of this Agreement, the Company

will prepare and file a prospectus in accordance with the provisions of Rule 430B of the Securities Act Regulations (“Rule 430B”) and paragraph (b) of Rule 424 (“Rule 424(b)”) of the Securities Act Regulations. Any information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.”

     Each prospectus used in connection with the offering of Offered Securities that omitted Rule 430B Information is herein called a “preliminary prospectus.” Such registration statement, at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference thereto pursuant to Item 12 of Form S-3 under the Act at such time and the documents otherwise deemed to be a part thereof or included therein by the Securities Act Regulations, and the Rule 430B Information is herein called the “Registration Statement.” The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The final prospectus in the form first furnished (electronically or otherwise) to the Underwriters for use in connection with the offering of the Offered Securities (whether to meet the requests of purchasers pursuant to Rule 173 under the Act or otherwise), including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Act at the time of execution of this Agreement, and any preliminary prospectuses that form a part thereof, is herein called the “Prospectus.” The Commission has not issued any order preventing or suspending the use of any preliminary prospectus.

     For purposes of this Agreement (other than in connection with any opinion given by counsel in Section 5 hereof, which hereby expressly excludes any copy filed via Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”)), all references to the “Original Registration Statement,” “Registration Statement,” the “Prospectus,” any “preliminary prospectus,” or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to EDGAR.

     All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by Securities Act Regulations to be a part of or included in the Registration Statement, any preliminary prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) which is incorporated by reference in or otherwise deemed by Securities Act Regulations to be a part of or included in the Registration Statement, such preliminary prospectus or the Prospectus, as the case may be.

The Transaction Entities and the Subsidiaries are in compliance with the terms and conditions of all such Licenses except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

     Q. Financial Statements. The financial statements included in or incorporated by reference into the Registration Statement, the Prospectus and the General Disclosure Package, together with the related schedules and notes, present fairly (1) the financial position of the Company and its consolidated Subsidiaries (and the combined financial position of any predecessor entities) at the dates indicated; and (2) the results of operations, stockholders’ equity and cash flows of the Company and its consolidated Subsidiaries (and the combined results of operations, stockholders’ equity, and cash flows of any predecessor entities) for the periods specified; said financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods involved; said financial statements have been prepared on a consistent basis with the books and records of the Company and its consolidated Subsidiaries (and any predecessor entities) in the case of the statements of financial position of the Company and its consolidated Subsidiaries (and the combined financial position of any predecessor entities) and the results of operations, stockholders’ equity and cash flows of the Company and its consolidated Subsidiaries (and the combined results of operations, stockholders’ equity, and cash flows of any predecessor entities). The supporting schedules incorporated by reference into the Registration Statement, the Prospectus and General Disclosure Package present fairly in accordance with GAAP the information required to be stated therein. All non-GAAP financial measures included in or incorporated by reference into the Registration Statement, the Prospectus and the General Disclosure Package comply with the requirements of Regulation G and Item 10 of Regulation S-K under the Act to the extent such rules are applicable to such financial statements. Other than the historical financial statements, and schedules relating thereto included in or incorporated by reference into the Registration Statement, the Prospectus and the General Disclosure Package, no other historical or pro forma financial statements (or schedules) are required by the Act or the Securities Act Regulations to be included therein or in any document required to be filed with the Commission under the Exchange Act or the Exchange Act Regulations.

     R. Independent Registered Public Accounting Firm. The accountants who certified the financial statements and supporting schedules included in or incorporated by reference into the Registration Statement and delivered the initial letter referred to in Section 5.A hereof, are an independent registered public accounting firm as required by the Act, the Securities Act Regulations, the Exchange Act, the Exchange Act Regulations, and the Public Company Accounting Oversight Board (United States).

     T. Tax Returns and Matters. The Transaction Entities and each of the Subsidiaries (including any predecessor entities) have filed all foreign, federal, state and local tax returns that are required to be filed or have requested extensions thereof (except in any case in which the failure so to file would not reasonably be expected to have a Material Adverse Effect) and have paid all taxes required to be paid by them and any other assessment, fine or penalty levied against them, to the extent that any of the foregoing is due and payable, except for any such assessment, fine or penalty that (i) is currently being contested in good faith, (ii) would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or (iii) as described in or contemplated by the Prospectus. Except as disclosed in the Prospectus, there is no pending or, to the knowledge of the Transaction Entities, threatened special assessment, tax reduction proceeding or other action which could increase or decrease the real property taxes or assessments of any Property, which would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

     U. No Other Offering Documents or Prospectuses. The Transaction Entities and each of the Subsidiaries have not distributed, and prior to the later of the First Closing Date and the completion of the distribution of the Offered Securities, will not distribute, any offering material in connection with the offering or sale of the Offered Securities other than the Registration Statement, the Prospectus, the General Disclosure Package or any other materials, if any, permitted by the Act (which were disclosed to the Representative and its counsel).

     V. ERISA Matters.

     (1) Each Transaction Entity is in compliance, in all material respects, with all presently applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”); no “reportable event” (as defined in ERISA other than an event for which the notice requirements have been waived by regulations) has occurred with respect to any “pension plan” (as defined in ERISA) for which any Transaction Entity would have any liability; no Transaction Entity has incurred or expects to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Sections 412 or 4971 of the Code including the regulations and published interpretations thereunder; and each “pension plan” for which any Transaction Entity would have any liability that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service that such plan is so qualified in all material respects and, except to the knowledge of the Transaction Entities, nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification, except where such non-compliance, reportable events, liabilities or failure to be so qualified would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

     (2) The assets of the Transactions Entities and the Subsidiaries do not constitute “plan assets” of an ERISA regulated employee benefit plan.

     (3) The Company is a “real estate operating company” as such term is defined in paragraph (e) of the plan assets regulation in 29 C.F.R. Section 2510.3-101, or will be an “operating company” as defined in the first sentence of paragraph (c) thereof.

     W. Property Matters.

     (1) The Transaction Entities or the Subsidiaries have good and marketable title (either in fee simple or pursuant to a leasehold interest) to all of the properties owned or leased by them (the “Properties”), in each case, free and clear of all Liens except such as (i) are disclosed in the Prospectus; or (ii) would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. Any real property, improvements, equipment and personal property held under lease by the Company or any Subsidiary are held under valid, existing and enforceable leases which are in full force and effect, and none of the Company, Operating Partnership nor any Subsidiary or, to any Transaction Entity’s knowledge, any other party, is in default under any such lease, with such exceptions as are disclosed in the Prospectus or would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect;

     (2) All of the leases and subleases under which the Company, Operating Partnership or any Subsidiary lease any portion of the Properties are in full force and effect; there are no uncured events of default, or events that with the giving of notice or passage of time, or both, would constitute an event of default, by any Transaction Entity nor any tenant under any of the terms and provisions of the leases described above; and none of the Company, Operating Partnership nor any Subsidiary has received any notice of any claim asserted by anyone adverse to the rights of the Company, Operating Partnership or Subsidiary under any of the leases or questioning or affecting the rights of the tenant of the continued possession of the leased or subleased premises under any such lease or sublease, in each case other than those that would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or that have been, in the reasonable judgment of the Company, adequately reserved for in the Company’s consolidated financial statements. Other than Arena Pharmaceuticals, Inc. and Centocor, Inc., no tenant which has been specifically identified in the Prospectus under any of the leases at the Properties has a right of first refusal to purchase the premises demised under such lease;

     (3) Except as disclosed in the Prospectus, none of the Transaction Entities, nor any Subsidiary, knows of any violation of any municipal, state or federal law, rule or regulation (including those pertaining to environmental matters) concerning the Properties or any part thereof which would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect;

     (4) Each of the Properties complies with all applicable zoning laws, ordinances, regulations, and deed restrictions or other covenants in all material respects

and, if and to the extent there is a failure to comply, such failure would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect;

     (5) None of the Transaction Entities, nor any Subsidiary, has received from any governmental authority any written notice of any condemnation of or zoning change affecting the Properties or any part thereof, and none of the Transaction Entities nor any Subsidiary or predecessor entity knows of any such condemnation or zoning change that is threatened against any of the Properties and that, if consummated, would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect;

     (6) Each of the Properties is free of material structural defects and all building systems contained therein are in good working order in all material respects, subject to ordinary wear and tear, except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, or, in each instance, the Company maintains adequate reserves to effect reasonably required repairs, maintenance and capital expenditures; and

     (7) Water, stormwater, sanitary sewer, electricity and telephone service are all available at the property lines of each Property over duly dedicated streets or perpetual easements of record benefiting the applicable Property, except as would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

     X. No Participating Interests. The mortgages and deeds of trust encumbering the Properties and assets described in the Prospectus are not convertible, and neither the Transaction Entities, any of the Subsidiaries, nor any person affiliated therewith holds a participating interest therein, and such mortgages and deeds of trust are not cross-defaulted or cross-collateralized to any property not owned directly or indirectly by the Transaction Entities or any of the Subsidiaries.

     Y. Insurance. The Operating Partnership and any Subsidiary that owns, or leases under ground leases, real property has obtained title insurance on the fee interests (or leasehold interests) in each of the Properties (other than one of the parcels at One Research Way) and other insurance covering such risks and in amounts that are commercially reasonable for the assets owned by them, and in each case such title insurance and other insurance is in full force and effect. Neither the Transaction Entities nor any of the Subsidiaries has any reason to believe that any of them will not be able to obtain or renew its existing insurance coverage as and when required by the preceding or as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business.

     (6) none of the Transaction Entities nor any of the Subsidiaries has received any notice of or is aware of any receipt by any other party of a notice of, or has any knowledge of any occurrence or circumstance that would give rise to a claim under or pursuant to any Environmental Law, pertaining to Hazardous Materials on or originating from any of the Properties or any assets described in the Prospectus (or, the most recent preliminary prospectus) or any other real property owned or occupied by any such party or arising out of the conduct of any such party, including without limitation a claim under or pursuant to any Environmental Law (as hereinafter defined);

2. Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the Underwriters, and the Underwriters agree,

severally and not jointly, to purchase from the Company, at a purchase price of $24.48 per share, the respective numbers of shares of Firm Securities set forth opposite the names of the Underwriters on Schedule I hereto.

     The Company will deliver the Firm Securities to the Representative for the accounts of the Underwriters, including, at the option of the Representative, through the facilities of The Depository Trust, against payment of the purchase price in federal (same day) funds by wire transfer to an account at a bank specified in writing to the Representative by the Company by 10:00 a.m., New York time, on April 22, 2008, or at such other time not later than seven full business days thereafter as the Representative and the Company determine, such time being herein referred to as the “First Closing Date.” For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. The Firm Securities will be delivered in such denominations and registered in such names as the Representative requests, and certificates for the Firm Securities, if any, will be in definitive form and will be made available for checking and packaging at the office of DLA Piper US LLP, 4141 Parklake Avenue, Suite 300, Raleigh, NC 27612 at least 48 hours prior to the First Closing Date.

     In addition, upon written notice from the Representative given to the Company from time to time not more than 30 days subsequent to the date of the Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per share to be paid for the Firm Securities. The Company agrees to sell to the Underwriters the number of Optional Securities specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of each Underwriter in the same proportion as the number of shares of Firm Securities set forth opposite such Underwriter’s name on Schedule I hereto bears to the total number of shares of Firm Securities (subject to adjustment by the Representative to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representative to the Company.

     Each time for the delivery of and payment for the Optional Securities, being herein referred to as an “Optional Closing Date,” which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by the Representative but shall be not later than five full business days after written notice of election to purchase Optional Securities is given. The Company will deliver the Optional Securities being purchased on each Optional Closing Date to the Representative for the accounts of the several Underwriters, against payment of the purchase price therefor in federal (same day) funds by official bank check or checks or wire transfer to an account at a bank acceptable to the Representative drawn to the order of BioMed Realty Trust, Inc., at the office of Latham & Watkins LLP. The certificates for the Optional Securities being purchased on each Optional Closing Date will be in definitive form, in such denominations and registered in such names as the Representative requests upon reasonable notice prior to such

Optional Closing Date and will be made available for checking and packaging at the office of DLA Piper US LLP at a reasonable time in advance of such Optional Closing Date.

     A. Additional Filings with the Commission. The Company will file the Prospectus with the Commission in the manner and within the time frame required by Rule 424(b) under the Act (without reliance on Rule 424(b)(8)) and will advise the Representative promptly of any such filing pursuant to Rule 424(b). The Company will furnish promptly to the Underwriters copies of the Prospectus and any amendments or supplements thereto in such quantities and at such locations as the Underwriters may reasonably request for the purposes contemplated by the Securities Act Regulations, which Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the version created to be transmitted to the Commission for filing via EDGAR, except to the extent permitted by Regulation S-T.

     B. Required Notices to and Consent of Representative Relating to Amendments or Supplements. The Company will advise the Representative promptly of (i) any proposal to amend or supplement the Registration Statement, the Prospectus or any preliminary prospectus and will not effect such amendment or supplement without the Representative’s consent; (ii) the effectiveness of any amendment or supplement to a Registration Statement or the Prospectus, (iii) the receipt of comments from the Commission, (iv) any request by the Commission for any amendment to the Registration Statement or the filing of a new registration statement or any amendment or supplement to the Prospectus or any document incorporated by reference or otherwise deemed to be a part thereof or for additional information; (v) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Offered Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the Act concerning the Registration Statement, or (vi) if the Company becomes the subject of a proceeding under Section 8A of the Act in connection with the offering of the Offered Securities. The Company will use its best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued. The Company shall pay the required Commission filing fees relating to the Offered Securities within the time required by Rule 456(b)(1)(i) of the Securities Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Securities Act Regulations (including, if applicable, by updating the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b)).

     C. Subsequent Events Requiring Amendment or Supplement. If, at any time when a Prospectus relating to the Offered Securities is required to be delivered under the Act in connection with sales by any Underwriter or dealer, any event occurs as a result of which the Prospectus as then amended or supplemented, in the judgment of the Company or the reasonable

opinion of the Representative or counsel for the Underwriters, would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Prospectus to comply with the Act, the Company will promptly notify the Representative of such event and will promptly prepare and furnish to the Underwriters copies of the proposed amendment or supplement before filing any such amendment or supplement with the Commission and thereafter promptly file with the Commission and furnish at the Company’s own expense to the Underwriters and to dealers, copies in such quantities and at such locations as the Representative may from time to time reasonably request of an appropriate amendment to the Registration Statement or supplement to the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the Act and the Securities Act Regulations. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement (or any other registration statement relating to the Offered Securities) or the Statutory Prospectus or any preliminary prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify the Representative and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. Neither the Representative’s consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 5. The Company has given the Representative notice of any filings made pursuant to the Exchange Act or the Exchange Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representative notice of its intention to make any such filing from the Applicable Time to the Closing Time and will furnish the Representative and counsel for the Underwriters with copies of any such documents a reasonable amount of time prior to such proposed filing and will not file or use any such document to which the Representative or counsel for the Underwriters shall reasonably object. The Company will prepare a final term sheet substantially in the form set forth on Schedule IV hereto (the “Final Term Sheet”) reflecting the final terms of the Offered Securities, and shall file such Final Term Sheet as an “issuer free writing prospectus” pursuant to Rule 433 prior to the close of business two business days after the date hereof; provided that the Company shall furnish the Representatives with copies of any such Final Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonably object.

     D. Twelve-Month Earnings Statement. As soon as practicable, but not later than the Availability Date (as hereinafter defined), the Company will make generally available to its securityholders an earnings statement covering a period of at least twelve months beginning after the effective date (as determined pursuant to Rule 158(c) under the Securities Act Regulations) of the Registration Statement which will satisfy the provisions of Section 11(a) of the Act. For the purpose of the preceding sentence, “Availability Date” means the 40th day after the end of the fourth fiscal quarter following the fiscal quarter that includes such effective date, except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the 75th day after the end of such fourth fiscal quarter.

     E. Copies of Documents. The Company will furnish to the Representative copies of the Original Registration Statement (one of which will be signed and will include all exhibits and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof), each related preliminary prospectus, and, so long as a prospectus relating to the Offered Securities is required to be delivered under the Act in connection with sales by any Underwriter or dealer, the Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Representative requests. All such documents shall be so furnished as soon as available. The Company will pay the expenses of printing and distributing to the Underwriters all such documents. The aforementioned documents furnished to the Underwriters or to any dealer shall be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T under the Act.

     F. Annual Reports. During the period of five years hereafter, the Company will furnish to the Representative and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, to the extent not available without charge through the Company’s website, a copy of its annual report to stockholders for such year and, shall furnish to the Representative, to the extent not available through EDGAR or any system succeeding or replacing EDGAR, as soon as available, a copy of each report of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and from time to time, such other information concerning the Company as the Representative may reasonably request.

     A. Accountant’s Letter. The Representative shall have received a letter at the time of execution of this Agreement, of KPMG LLP (“KPMG”) in the form approved by the

Representative before the execution of this Agreement, with respect to the financial statements and certain financial information set forth in or incorporated by reference in the Registration Statement and Prospectus, which shall include the following statements:

     (2) in their opinion the financial statements examined by them and included in or incorporated by reference into the Registration Statements comply as to form in all material respects with the applicable requirements of the Act and the Securities Act Regulations;

     (3) on the basis of a reading of the latest available interim financial statements of the Company, inquiries of officials of the Company who have responsibility for financial and accounting matters, and other specified procedures, nothing came to their attention that caused them to believe that:

     (a) at the date of the latest available balance sheet read by such accountants, and at a subsequent specified date not more than three business days prior to the date of this Agreement, there was any change in the capital stock or any increase in debt of the Company or, at the date of the latest available balance sheet read by such accountants, there was any decrease in net assets or stockholders’ equity, as compared with amounts shown on the latest balance sheets included in or incorporated by reference into the Prospectus; or

     (b) for the period from the closing date of the latest income statement included in or incorporated by reference into the Prospectus to the closing date of the latest available income statement read by such accountants there were any decreases, as compared with the corresponding period of the previous year for the operations of the Company and with the period of corresponding length ended the date of the latest income statement included in or incorporated by reference into the Prospectus, in total revenues or net income.

     except in all cases set forth in one of the above clauses for changes, increases or decreases which the Prospectus discloses have occurred or may occur or which are described in such letter;

     (4) they have compared specified dollar amounts (or percentages derived from such dollar amounts) and other financial information contained in the Registration Statements (in each case to the extent that such dollar amounts, percentages and other financial information are derived from the general accounting records of the Company subject to the internal controls of the Company’s accounting system, a reading of such general accounting records and other procedures specified in such letter and have found such dollar amounts, percentages and other financial information to be in agreement with such results, except as otherwise specified in such letter.

For purposes of this subsection, “Registration Statements” shall mean the Registration Statement, including the prospectus included in the Registration Statements and any preliminary prospectus.

     B. Registration Statement Effectiveness. The Registration Statement has become effective and at the Closing Date, no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Company, shall be contemplated by the Commission. The Prospectus containing the Rule 430B Information shall have been filed with the Commission in the manner and within the time frame required by Rule 424(b) without reliance on Rule 424(b)(8) (or a post-effective amendment providing such information shall have been filed and become effective in accordance with the requirements of Rule 430B) in accordance with Section 4 of this Agreement. The Company shall have paid the required Commission filing fees relating to the Offered Securities within the time period required by Rule 456(1)(i) of the Securities Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Securities Act Regulations and, if applicable, shall have updated the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b).

     C. Subsequent Events. Subsequent to the execution and delivery of this Agreement, and since the respective dates as of which information is given in the Prospectus or the General Disclosure Package, there shall not have occurred:

     (1) any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties, earnings, results of operations or prospects of the Company and its Subsidiaries taken as one enterprise, whether or not in the ordinary course, which, individually or in the aggregate, in the sole judgment of the Representative, is material and adverse and makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Offered Securities;

     (2) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the sole judgment of the Representative, be likely to prejudice materially the success of the proposed issue, sale or distribution of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market;

     (3) any suspension or limitation of trading in securities generally on the NYSE, or any setting of minimum prices for trading on such exchange;

     (7) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity, crisis or emergency if, in the reasonable judgment of the Representative, the effect of any such attack, outbreak, escalation, act, declaration, calamity, crisis or emergency makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Offered Securities.

     D. Issuer’s Counsel’s Opinion. The Representative shall have received an opinion, dated on such Closing Date, of Latham & Watkins LLP, special counsel for the Company, to the effect that:

     (1) Based solely on certificates from public officials, such counsel confirms that the Company is qualified to do business in California;

     (2) Based solely on certificates from public officials, such counsel confirms that the Operating Partnership is qualified to do business in the following states: California, Colorado, Delaware, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania and Washington;

     (3) Each of the Subsidiaries of the Company or the Operating Partnership listed on a schedule to such counsel’s opinion (the “Material Subsidiaries”) is either (a) a limited liability company duly organized under the Delaware Limited Liability Company Act (the “DLLCA”) with limited liability company power and authority to own its properties and to conduct its business as described in the Registration Statement and the Prospectus, or (b) a limited partnership duly organized under the Delaware Revised Uniform Limited Partnership Act (the “DRULPA”) with limited partnership power and authority to own its properties and to conduct its business as described in the Registration Statement and the Prospectus. Based solely on certificates from public officials, such counsel confirms that each Material Subsidiary is validly existing and in good standing under the laws of the state of its formation, and is qualified to do business in all states set forth on a schedule to such counsel’s opinion. With your consent, based solely upon a certificate of an officer of the Company and the Operating Partnership as to factual matters and a review of the limited liability company agreements or agreements of limited partnership of each Material Subsidiary, all of the partnership interests or limited liability company interests of the Material Subsidiaries are owned of record by the Company, the Operating Partnership, or a wholly owned subsidiary of the Company or the Operating Partnership.

     (4) With the consent of the Representative based solely on a certificate of an officer of the Transaction Entities as to factual matters, each of the Company and the Operating Partnership is not, and immediately after giving effect to the sale of the Offered Securities in accordance with the Underwriting Agreement and the application of the proceeds as described in the Prospectus under the caption “Use Of Proceeds” will not

be required to be registered as, an “investment company” within the meaning of the Investment Company Act;

     (5) The execution and delivery of the Underwriting Agreement by the Transaction Entities, and the issuance and sale of the Offered Securities by the Company to the Underwriters pursuant to the Underwriting Agreement do not on the date hereof:

     (a) conflict with, result in the breach of or a default under any of the agreements filed as or incorporated by reference as exhibits to the Registration Statement;

     (b) violate any federal or California statute, rule or regulation applicable to any such Transaction Entities;

     (c) violate the certificate of formation, certificate of partnership, limited liability company agreement or agreement of limited partnership of any Material Subsidiary; or

     (d) require any consents, approvals, or authorizations to be obtained by any such Transaction Entities or any Material Subsidiary, or any registrations, declarations or filings to be made by such Transaction Entities, in each case, with any governmental authority under any federal or California statute, rule, or regulation applicable to the Transaction Entities on or prior to the date of such opinion that have not been obtained or made;

     (6) The Registration Statement has become effective under the Act. With the consent of the Representative, based solely on telephonic confirmation by a member of the Staff of the Commission on the date of such opinion, such counsel confirms that no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated by the Commission. The preliminary prospectus has been filed in accordance with Rule 424(b) under the Act, the Prospectus has been filed in accordance with Rule 424(b) and 430B under the Act (without reference to Rule 424(b)(8)), and the Issuer Free Writing Prospectus has been filed in accordance with Rule 433(d) under the Act;

     (7) To the best knowledge of such counsel, there are no contracts or documents of a character required to be described in the Registration Statement or Prospectus or the Incorporated Documents or to be filed as exhibits to the Registration Statement that are not described or filed or incorporated by reference as exhibits thereto; it being understood, however, that such counsel expresses no view with respect to the financial statements, schedules, or other financial data, included in, incorporated by reference in, or omitted from, the Registration Statement, the Incorporated Documents or the Prospectus;

     (8) To the best knowledge of such counsel, based solely on oral or written statements and representations of officers and other representatives of the Transaction Entities, including the representations and warranties of the Transaction Entities in this agreement, and docket searches in the jurisdictions listed on a schedule to such counsel’s

opinion, there are no actions, suits, proceedings or investigations pending against the Transaction Entities before any court, governmental agency or arbitrator which are required to be disclosed in the Prospectus pursuant to Item 103 of Regulation S-K under the Act, other than those disclosed therein. Such counsel’s opinion may note that docket searches may be unreliable and may not accurately reflect proceedings before the respective courts and that such counsel has not undertaken any independent investigation to determine the accuracy of the docket searches;

     (9) The Registration Statement, including without limitation the 430B Information, as of its latest effective date and as of the date of the Prospectus, and the Prospectus, as of its date, appeared on its face to be appropriately responsive in all material respects to the applicable form requirements for registration statements on Form S-3 under the Act and the Securities Act Regulations; it being understood, however, that such counsel need express no view with respect to Regulation S-T or the financial statements, schedules, or other financial data, included in, or omitted from, the Registration Statement or Prospectus. For purposes of this paragraph, such counsel may assume that the statements made in the Registration Statement and Prospectus are correct and complete;

     (10) Each of the Incorporated Documents, as of its respective filing date, appeared on its face to be appropriately responsive in all material respects to the applicable requirements for reports on Form 8-A, Form 10-K, Form 10-Q and Form 8-K and proxy statements under Regulation 14A, as the case may be, under the Exchange Act and the Exchange Act Regulations; it being understood, however, that such counsel expresses no opinion with respect to Regulation S-T or the financial statements, schedules or other financial data included in, incorporated by reference in, or omitted from, the Incorporated Documents. For purposes of this paragraph, such counsel may assume that the statements made in the Incorporated Documents are correct and complete;

     (11) Except for the Unitholder Registration Rights Agreements, the Notes Registration Rights Agreement and the JV Registration Rights Agreement, to the best knowledge of such counsel, no Transaction Entity is a party to any agreement that would (a) require the inclusion in the Registration Statement of any securities of the Company owned by any person or entity other than the Company or (b) entitle such person to require the Company to file a registration statement under the Act with respect to any securities of the Company; and

     In rendering such opinions, such counsel may limit its opinions to the federal laws of the United States of America and the laws of the state of California, and matters specifically governed thereby. In rendering such opinions, such counsel may also rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

     In addition, such counsel shall state in a separate letter that:

     The primary purpose of its professional engagement was not to establish or confirm factual matters or financial or quantitative information. Therefore, such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in, or incorporated by reference in, the Registration Statement, the Prospectus and the General Disclosure Package (except to the extent expressly set forth in the numbered paragraph 7 of such counsel’s opinion letter to the Representative of even date), and has not made an independent check or verification thereof (except as aforesaid). However, in the course of acting as special counsel to the Company in connection with the preparation by the Company of the Registration Statement, the Prospectus and the General Disclosure Package, such counsel reviewed the Registration Statement, the Prospectus, the General Disclosure Package and the Incorporated Documents, and participated in conferences and telephone conversations with officers and other representatives of the Company, the independent registered public accounting firm for the Company, the representatives of the Underwriters, and counsel to the Underwriters, during which conferences and conversations the contents of the Registration Statement, the Prospectus, the General Disclosure Package and the Incorporated Documents and related matters were discussed. Such counsel also reviewed and relied upon certain corporate records and documents, letters from counsel and accountants, and oral and written statements of officers and other representatives of the Company and others as to the existence and consequence of certain factual and other matters.

     Based on such counsel’s participation, review and reliance as described above, such counsel advises the Representative that no facts came to such counsel’s attention that caused such counsel to believe that:

	•		the Registration Statement, at the date of the Prospectus, including the 430B Information (together with the Incorporated Documents at that time), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;
	•		the General Disclosure Package, as of the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of circumstances under which they were made, not misleading; or
	•		the Prospectus, as of its issue date or as of the date of such counsel’s opinion (together with the Incorporated Documents at those dates), contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that such counsel expresses no belief with respect to the financial statements, schedules, or other financial data included or incorporated by reference in, or omitted from, the Registration Statement, the Prospectus, the General Disclosure Package or the Incorporated Documents.

     E. Tax Opinion. The Representative shall have received an opinion, dated such Closing Date, of Latham & Watkins LLP, special tax counsel for the Company, to the effect that:

     (1) Commencing with its taxable year ending December 31, 2004, the Company has been organized and has operated in conformity with the requirements for qualification as a REIT under the Code, and its proposed method of operation will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code; and

     (2) The statements in the Registration Statement set forth under the caption “Material Federal Income Tax Considerations” insofar as they purport to summarize certain provisions of the statutes or regulations referred to therein, are accurate summaries in all material respects.

     In rendering such opinion, such counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials. In addition, in rendering such opinion, counsel may rely on and assume the accuracy of an opinion of Venable LLP (“Venable”), special Maryland counsel of the Company, dated as of the Closing Date, with respect to certain matters of Maryland law.

     F. Venable Opinion. The Representative shall have received an opinion, dated such Closing Date, of Venable, special Maryland counsel of the Company, to the effect that:

All of the issued and outstanding shares of capital stock of BioMed Holdings have been duly authorized and validly issued and are fully paid and non-assessable. With your consent, based solely upon a certificate of an officer of the Company as to factual matters dated the Closing Date and a review of the charter and bylaws, all of the outstanding capital stock of BioMed Holdings is owned of record by the Company.

     (4) The Company has an authorized capitalization as set forth in the Prospectus under the caption “Capitalization,” and the issued and outstanding shares of

the Company (other than the Offered Securities) (the “Company Outstanding Shares”) have been duly authorized and validly issued and are fully paid and non-assessable. The terms of the Company Outstanding Shares conform, in all material respects, to the statements and descriptions related thereto contained in the Prospectus under the captions “Description of Common Stock” and “Description of Preferred Stock.” The issuance of the Company Outstanding Shares by the Company was not subject to preemptive or other similar rights arising under the Maryland General Corporation Law (the “MGCL”), the Company’s articles of incorporation, including the Articles Supplementary (the “Charter”) or bylaws (the “Bylaws”). The certificate for the Common Stock complies in all material respects with the applicable requirements of the MGCL, the Charter, and the Bylaws.

     (5) The Company has the full corporate power to authorize, issue, and sell the Offered Securities as contemplated by this Agreement. The issuance of the Offered Securities has been duly authorized and, when issued and delivered by the Company pursuant to the Resolutions and this Agreement against payment of the consideration set forth herein, the Offered Securities will be validly issued, fully paid and non-assessable and will conform, in all material respects, to the description thereof contained in the Prospectus under the caption “Description of Common Stock.” The issuance of the Offered Securities by the Company is not subject to preemptive or other similar rights arising under the MGCL, the Charter or the Bylaws.

     (6) The outstanding OP Units and series A preferred units of limited partnership interest in the Operating Partnership have been duly authorized and validly issued and are fully paid and non-assessable.

The terms of the OP Units conform, in all material respects, to the description thereof contained in the Prospectus under the caption “Description of the Partnership Agreement of BioMed Realty, L.P.”

     (7) The execution, delivery and performance of this Agreement, and the transactions contemplated thereby and the sale and issuance of the Offered Securities do not conflict with or result in a breach or violation of, or constitute a default under, (a) any Maryland law, or any decree, rule or regulation of any Maryland governmental authority applicable to the Transaction Entities or (b) the Charter, the Bylaws or the Operating Partnership Agreement.

     (8) The execution and delivery of this Agreement have been duly authorized by all necessary corporate or limited partnership action, as applicable, of each Transaction Entity that is a party hereto. This Agreement has been executed and, so far as is known to such counsel, delivered by each Transaction Entity that is a party hereto. The Operating Partnership Agreement constitutes the legal, valid, and binding obligation of each Transaction Entity that is a party thereto, enforceable against each Transaction Entity that is a party thereto in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium, and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity and, with respect to equitable relief, the discretion of the court before which any proceeding therefor may be brought (regardless of whether enforcement is sought in a proceeding at law or in equity).

     (9) The information included in or incorporated by reference to the Prospectus under the captions “Risk Factors—Risks Related to Our Organizational Structure,” “Description of Preferred Stock,” “Description of Common Stock,” “Description of Units,” “Restrictions on Ownership and Transfer,” “Certain Provisions of Maryland Law and of Our Charter and Bylaws” and “Description of the Partnership Agreement of BioMed Realty, L.P.,” as of the date of the Prospectus, insofar as such information relates to provisions of Maryland law or the Company’s or the Operating Partnership’s organizational documents is accurate in all material respects.

     (10) The execution, delivery and performance of this Agreement and the transactions contemplated hereby and the sale and issuance of the Offered Securities do not require any consents, approvals, authorizations, or orders to be obtained by any such Transaction Entities, or any registrations, declarations, or filings to be made by such Transaction Entities, in each case, under any Maryland statute, rule, or regulation applicable to the Transaction Entities that have not been obtained or made.

     In rendering such opinions, such counsel may limit its opinions to the laws of the state of Maryland, and matters specifically governed thereby. In rendering such opinion, such counsel may rely, as to matters of fact (but not as to legal conclusions), to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

     G. Underwriters’ Counsel’s Opinion. On any Closing Date other than the First Closing Date, the Representative shall have received from DLA Piper US LLP, counsel for the Underwriters, such opinion or opinions, dated such Closing Date, with respect to the incorporation of the Company, the validity of the Offered Securities delivered on such Closing Date, the Registration Statements, the Prospectus and other related matters as the Representative may require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

     A. The Transaction Entities, jointly and severally, will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees and agents and each person, if any, who controls such Underwriter within the meaning of the Act or the Exchange Act, against any losses, claims, damages, liabilities or expenses, joint or several, to which any of them may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation or at common law, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, the Prospectus, any related preliminary prospectus, or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each indemnified party for any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such loss, claim, damage, liability, action or expense as such expenses are incurred; provided, however, that the Transaction Entities will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 6.B below.

     B. Each Underwriter severally and not jointly will indemnify and hold harmless each Transaction Entity, each of its directors and officers who signs the Registration Statement or who consents to being named as a director upon the First Closing Date and each person, if any who controls the Company within the meaning of the Act or the Exchange Act, against any losses, claims, damages, liabilities or expenses to which any of them may become subject, under the Act, the Exchange Act or other federal or state statutory law or regulation or at common law or otherwise, insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement, the Prospectus, any related preliminary prospectus, or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written

information furnished to the Company by such Underwriter through the Representative specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by each indemnified party in connection with investigating or defending any such loss, claim, damage, liability, action or expense as such expenses are incurred, it being understood and agreed that the only such information furnished on behalf of each Underwriter consists of the following information: the list of Underwriters and their respective participation in the sale of the Offered Securities, the concession and reallowance sentences and the paragraphs related to stabilization, syndicate covering transactions and penalty bids appearing under the caption “Underwriting” in the Prospectus.

     C. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under Section 6.A or 6.B above, notify, in writing, the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party otherwise than under Section 6.A or 6.B above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to the last paragraph in Section 6.A hereof in respect to such action or proceeding, then, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for the indemnified parties. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party, and (iii) does not include any undertaking or obligation to act or to refrain from acting by the indemnified party.

     D. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under Section 6.A or 6.B above for any reason, then each indemnifying party (with respect to the Transaction Entities, jointly and severally) shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in Section 6.A or 6.B above (i) in such proportion as is appropriate to reflect the relative benefits received by the Transaction Entities on the one hand and one or more of the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law,

in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Transaction Entities on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative benefits received by the Transaction Entities on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Transaction Entities bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Transaction Entities or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to in the first sentence of this Section 6.D shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this Section 6.D. Notwithstanding the provisions of this Section 6.D, no Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Offered Securities) shall be required to contribute any amount in excess of the underwriting discount or commission applicable to the Offered Securities purchased by such Underwriter hereunder. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 6.D to contribute are several in proportion to their respective underwriting obligations and not joint. The Transaction Entities and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or another method of allocation that does not take account of the equitable considerations referred to above.

     E. The obligations of the Transaction Entities under this Section shall be in addition to any liability that the Transaction Entities may otherwise have and shall extend, upon the same terms and conditions, to each partner, member, director, officer, employee or agent of any Underwriter and any person, if any, who controls any Underwriter within the meaning of the Act or the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Transaction Entities, to each officer of the Transaction Entities who has signed a Registration Statement and to each person, if any, who controls the Transaction Entities within the meaning of the Act.

7. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Representative may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered

Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representative and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 6 above (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

8. Expenses. Whether or not the transactions contemplated hereby are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid the following: (1) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the registration of the Offered Securities under the Act and all other filing fees, other fees and expenses in connection with the preparation, printing and filing of the Registration Statement and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof and of any Preliminary Prospectus and any Permitted Free Writing Prospectus to the Underwriters and dealers; (2) the printing and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, the Prospectus, each Preliminary Prospectus, any Blue Sky memoranda, this Agreement and all amendments or supplements to any of them as may be reasonably requested for use in connection with the offering and sale of the Offered Securities; (3) all expenses in connection with the qualification of the Offered Securities for offering and sale under state securities laws or Blue Sky laws, including reasonable attorneys’ fees and out-of-pocket expenses of the counsel for the Underwriters in connection therewith; (4) the filing fees incident to securing any required review by the FINRA of the fairness of the terms of the sale of the Offered Securities; (5) the fees and expenses associated with listing the Offered Securities on the NYSE; (6) the cost of preparing stock certificates; (7) the costs and charges of any transfer agent or registrar; (8) the cost of the tax stamps, if any, in connection with the issuance and delivery of the Offered Securities to the respective Underwriters; (9) all other fees, costs and expenses referred to in Item 31 of the Registration Statement; and (10) the transportation, lodging, graphics and other expenses incidental to the Company’s preparation for and participation in any “roadshow” for the offering contemplated hereby. Except as provided in this Section 8 and in Section 7 hereof, the Underwriters shall pay their own expenses, including the fees and disbursements of their counsel.

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Transaction Entities or their respective officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Transaction Entities or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to

Section 7 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 4 and Section 8 and the respective obligations of the Transaction Entities and the Underwriters pursuant to Section 6 shall remain in effect, and if any Offered Securities have been purchased hereunder the representations and warranties in Section 1 and all obligations under Section 4 shall also remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 7 or the occurrence of any event specified in Sections 5.C(2), 5.C(3), 5.C(5), 5.C(6), or 5.C(7), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.
