Ladies and Gentlemen:

Franklin Street Properties Corp., a Maryland corporation (the “Company”), confirms its agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill Lynch”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Merrill Lynch, Robert W. Baird & Co. Incorporated and BMO Capital Markets Corp. are acting as representatives (in such capacity, the “Representatives”), with respect to (i) the sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective numbers of shares of Common Stock, par value $0.0001 per share, of the Company (“Common Stock”) set forth in Schedules A and B hereto and (ii) the grant by the Company to the Underwriters, acting severally and not jointly, of the option described in Section 2(b) hereof to purchase all or any part of 2,250,000 additional shares of Common Stock.  The aforesaid 15,000,000 shares of Common Stock (the “Initial Securities”) to be purchased by the Underwriters and all or any part of the 2,250,000 shares of Common Stock subject to

the option described in Section 2(b) hereof (the “Option Securities”) are herein called, collectively, the “Securities.”

The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (File No. 333-181009) covering the public offering and sale of certain securities, including the Securities, under the Securities Act of 1933, as amended (the “1933 Act”), and the rules and regulations promulgated thereunder (the “1933 Act Regulations”), which automatic shelf registration statement became effective upon filing under Rule 462(e) under the 1933 Act Regulations (“Rule 462(e)”). Such registration statement, as of any time, means such registration statement as amended by any post-effective amendments thereto to such time, including the exhibits and any schedules thereto at such time, the documents incorporated or deemed to be incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to Rule 430B under the 1933 Act Regulations (“Rule 430B”), and is referred to herein as the “Registration Statement;” provided, however, that the “Registration Statement” without reference to a time means such registration statement as amended by any post-effective amendments thereto as of the time of the first contract of sale for the Securities, which time shall be considered the “new effective date” of such registration statement with respect to the Securities within the meaning of paragraph (f)(2) of Rule 430B, including the exhibits and schedules thereto as of such time, the documents incorporated or deemed incorporated by reference therein at such time pursuant to Item 12 of Form S-3 under the 1933 Act and the documents otherwise deemed to be a part thereof as of such time pursuant to the Rule 430B.  Each preliminary prospectus used in connection with the offering of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are collectively referred to herein as a “preliminary prospectus.”  Promptly after execution and delivery of this Agreement, the Company will prepare and file a final prospectus relating to the Securities in accordance with the provisions of Rule 424(b) under the 1933 Act Regulations (“Rule 424(b)”).  The final prospectus, in the form first furnished or made available to the Underwriters for use in connection with the offering of the Securities, including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, are collectively referred to herein as the “Prospectus.”  For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (or any successor system) (“EDGAR”).

On April 3, 2013, FSP 1999 Broadway LLC, a wholly-owned subsidiary of the Company, entered into an agreement to purchase a multi-tenant office building located in Denver, Colorado, from Pearlmark Broadreach 1999, L.L.C., and, on March 8, 2013, FSP 999 Peachtree Street LLC, a wholly-owned subsidiary of the Company, entered into an agreement to purchase a multi-tenant office building  located in Atlanta, Georgia, from Jamestown 999 Peachtree, L.P.  These agreements are collectively referred herein as the “Acquisition Agreements” and the properties to be acquired by the Company pursuant to such agreements are collectively referred to herein as the “Acquisition Properties”.

“General Disclosure Package” means any Issuer General Use Free Writing Prospectuses issued at or prior to the Applicable Time, the most recent preliminary prospectus (including any documents incorporated therein by reference) that is distributed to investors prior to the Applicable Time and the information included on Schedule C hereto, all considered together.

SECTION 1.                            Representations and Warranties.

(i)                                     Registration Statement and Prospectuses.  The Company meets the requirements for use of Form S-3 under the 1933 Act.  The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405) and the Securities have been and remain eligible for registration by the Company on such automatic shelf registration statement.  Each of the Registration Statement and any post-effective amendment thereto has become effective under the 1933 Act.  No stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto has been issued under the 1933 Act, no order preventing or suspending the use of any preliminary prospectus or the Prospectus has been issued and to the Company’s knowledge, no proceedings for any of those purposes have been instituted or are

3

pending or are contemplated.  The Company has complied with each request (if any) from the Commission for additional information.

Each of the Registration Statement and any post-effective amendment thereto, at the time of its effectiveness and at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) under the 1933 Act Regulations, complied in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations.  Each preliminary prospectus, the Prospectus and any amendment or supplement thereto or any prospectus wrapper prepared in connection therewith, at the time each was filed with the Commission, complied in all material respects with the requirements of the 1933 Act Regulations and each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, when they became effective or at the time they were or hereafter are filed with the Commission, complied and will comply in all material respects with the requirements of the 1934 Act and the rules and regulations of the Commission under the 1934 Act (the “1934 Act Regulations”).

(ii)                                  Accurate Disclosure.  Neither the Registration Statement nor any amendment thereto, at its effective time, at the Closing Time or at any Date of Delivery, contained, contains or will contain an untrue statement of a material fact or omitted, omits or will omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.  As of the Applicable Time, neither (A) the General Disclosure Package nor (B) any individual Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.  Neither the Prospectus nor any amendment or supplement thereto (including any prospectus wrapper), as of its issue date, at the time of any filing with the Commission pursuant to Rule 424(b), at the Closing Time or at any Date of Delivery, included, includes or will include an untrue statement of a material fact or omitted, omits or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.  The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus, at the time the Registration Statement became effective or when such documents incorporated by reference were filed with the Commission, as the case may be, when read together with the other information in the Registration Statement, the General Disclosure Package or the Prospectus, as the case may be, did not and will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the General Disclosure Package and the Prospectus, in light of the circumstances under which they were made) not misleading.

The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement (or any amendment thereto), the General Disclosure Package, any individual Issuer Limited Use Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) (including any prospectus wrapper) made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.  For purposes of this Agreement, the only information so furnished shall be the information in the first paragraph under the heading “Underwriting—

4

The Company and its Subsidiaries have reasonably concluded that the costs and liabilities associated with compliance with Environmental Laws are not, singly, or in the aggregate, reasonably expected to have a Material Adverse Effect, except as set forth in the Registration Statement, the General Disclosure Package and the Prospectus.

(xxxi)                Intellectual Property.  Each of the Company and its Subsidiaries, to the knowledge of the Company, owns or possesses all inventions, patent applications, patents, trademarks (both registered and unregistered), trade names, service names, copyrights, trade secrets and other proprietary information described in the Registration Statement, the General Disclosure Package and the Prospectus as being owned or licensed by it or which is necessary for the conduct of, or material to, its businesses (collectively, the “Intellectual Property”), and the Company is unaware of any claim to the contrary or any challenge by any other person to the rights of the Company or any of its Subsidiaries with respect to the Intellectual Property, except for any claim or challenge that would not reasonably be expected to result in a Material Adverse Effect.  To the knowledge of the Company, neither the Company nor any of its Subsidiaries has infringed or is infringing the material intellectual property of a third party, and neither the Company nor any of its Subsidiaries has received written notice of a claim by a third party to the contrary.

(xxxiii)          Insurance.  The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility, against such losses and risks and in such amounts as are customary in the businesses in which they are engaged.  Neither the Company nor any of its Subsidiaries has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not reasonably be expected to have a Material Adverse Effect.

(xxxiv)         Possession of Licenses and Permits. The Company and its Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct their respective businesses, except for such

11

certificates, authorizations or permits the lack of which would not reasonably be expected to result in a Material Adverse Effect, and neither the Company nor any of its Subsidiaries has received any written notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would reasonably be expected to have a Material Adverse Effect or materially and adversely affect the value of such Property (as described below) or materially interfere with the use, or proposed use, of such Property.

(xxxv)            Internal Control Over Financial Reporting.  The Company maintains “internal control over financial reporting” (as defined in Rules 13a-15 and 15d-15 under the 1934 Act) in compliance with the requirements of the 1934 Act.  The Company’s internal control over financial reporting has been designed by the Company’s principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and is effective in performing the functions for which it was established.  Except as described in the Registration Statement, General Disclosure Package or Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (i) no significant deficiency or material weakness in the design or operation of the Company’s internal control over financial reporting (whether or not remediated) which is reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information, and (ii) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.  The Company and its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that the Company qualifies as a real estate investment trust (a “REIT”) under the requirements of the Internal Revenue Code of 1986, as amended (the “Code”).

(xxxvi)         Disclosure Controls and Procedures. The Company maintains “disclosure controls and procedures” (as such term is defined in Rules 13a-15 and 15d-15 under the 1934 Act); such disclosure controls and procedures are designed to ensure that material information relating to the Company, including its consolidated Subsidiaries, is made known to the Company’s Chief Executive Officer and Chief Financial Officer by others within those entities, and such disclosure controls and procedures are effective at the reasonable assurance level in performing the functions for which they were established; the principal executive officers (or their equivalents) and principal financial officers (or their equivalents) of the Company have made all certifications required by the Sarbanes-Oxley Act of 2002 and any related rules and regulations promulgated by the Commission (the “Sarbanes-Oxley Act”), and the statements made in each such certification are accurate; the Company and its Subsidiaries and, to the Company’s knowledge, their respective directors and officers (in their capacities as such) are in compliance in all material respects with the applicable provisions of the Sarbanes-Oxley Act.

(xxxvii)      Taxes.  All U.S. federal, state, local and foreign tax returns required to be filed by the Company or any of its Subsidiaries have been timely filed, and all material taxes and other assessments of a similar nature (whether imposed directly, through withholding or otherwise) including any interest, additions to tax or penalties applicable thereto due or claimed to be due from such entities have been timely paid, other than those being contested in good faith and for which adequate reserves have been provided on the books of the applicable entity.  The Company and its Subsidiaries have established adequate reserves for all taxes that have accrued but are not yet due and payable.  No tax deficiency has been asserted against any such entity, nor does the Company or any of its Subsidiaries know of any tax deficiency which is likely to be asserted

12

against any such entity that, if determined adversely to any such entity, could reasonably be expected to have a Material Adverse Effect.

(xxxviii)                                                   Qualification as REIT.  The Company elected to be taxed as a REIT under the Code commencing with its taxable year ended December 31, 2002.  Commencing with the taxable year ended December 31, 2002 and through the date hereof, the Company has been organized and operated in conformity with the requirements for qualification and taxation as a REIT under the Code, and its current and proposed ownership and method of operation will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code for its taxable year ending December 31, 2013 and in the future.  The Company intends to continue to qualify as a REIT under the Code for all subsequent years.  The Company does not know of any event that would reasonably be expected to cause the Company to fail to qualify as a REIT under the Code for its taxable year ending December 31, 2013 or at any time thereafter.

(xxxix)         Legal, Tax and Accounting Advice.  The Company has not relied upon the Representatives or legal counsel for the Representatives for any legal, tax or accounting advice in connection with the offering and sale of the Securities.

(xl)                              Tax Disclosures.  The factual description of, and the assumptions and representations regarding, the Company’s organization and current and proposed method of operation set forth in the Prospectus under the headings “Material United States Federal Income Tax Considerations” and “Supplemental Federal Income Tax Considerations” accurately summarizes in all material respects the matters referred to therein.

(xli)                           ERISA Compliance.  Neither the Company nor any of its Subsidiaries maintains or contributes to any “pension plan” (within the meaning of Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) that is subject to Title IV of ERISA or any “multiemployer plan” (within the meaning of Section 4001(a)(3) of ERISA).  Each “pension plan” (within the meaning of Section 3(2) of ERISA) maintained by the Company or any of its Subsidiaries which is intended to be qualified under Section 401(a) of the Code has received a favorable determination or opinion letter from the Internal Revenue Service that such plan is so qualified (or the Company or such Subsidiaries have timely completed Internal Revenue Service Form 8905, Certification of Intent to Adopt a Pre-approved Plan).  Each “employee benefit plan” (within the meaning of Section 3(3) of ERISA) established or maintained by the Company and/or one or more of its Subsidiaries is in compliance with the currently applicable provisions of ERISA, except for such failures to comply that would not individually or in the aggregate reasonably be expected to result in a Material Adverse Effect.

(xlii)                        Unlawful Contributions or Payments.  Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder; and the Company and its Subsidiaries have instituted and maintain policies and procedures designed to ensure continued compliance therewith, including without limitation a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded

13

accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(xliii)                     OFAC.  None of the Company, any of its subsidiaries or, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is an individual or entity (“Person”) currently the target of any sanctions enforced by the United States Government, including, without limitation, the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”) (collectively, “Sanctions”), nor is the Company located, organized or resident in a country or territory that is the subject of Sanctions; and the Company will not directly or indirectly use the proceeds of the sale of the Securities, or lend, contribute or otherwise make available such proceeds to any subsidiaries, joint venture partners or other Person, for the specific purpose of funding any activities of or business of any Person, or in any country or territory, that, at the time of such funding, is the subject of  Sanctions.

(xliv)                    Money Laundering.  The operations of the Company are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, applicable money laundering statutes of all jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened.

(xlv)                       No Integration.  The Company has not sold or issued any securities that would be integrated with the offering of Securities pursuant to the 1933 Act and the 1933 Act Regulations or the interpretations thereof by the Commission.

(xlvi)                    Absence of Manipulation.  Neither the Company nor any affiliate of the Company has taken, nor will the Company or any affiliate take, directly or indirectly, any action which is designed, or would be expected, to cause or result in, or which constitutes, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities or to result in a violation of Regulation M under the 1934 Act.

(xlvii)                 Lending Relationship.  Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, the Company (i) does not have any material lending or other relationship with any bank or lending affiliate of any Underwriter and (ii) does not intend to use any of the proceeds from the sale of the Securities to repay any outstanding debt owed to any affiliate of any Underwriter.

(xlviii)              Authorization and Description of the Acquisition Agreements. The Acquisition Agreements have been duly and validly authorized, executed and delivered by the applicable Subsidiary on behalf of the Company, and to the knowledge of the Company, by each of the other parties thereto and constitute valid and binding agreements of the parties thereto, enforceable in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally or by general principles of equity; and to the knowledge of the Company, the descriptions of the Acquisition Agreements contained in the Registration Statement, the General Disclosure Package and the Prospectus, as the case may be, constitute a complete and accurate description of the material terms thereof.

14

(xlix)                    Acquisition Properties.  To the knowledge of the Company, the representations and warranties contained in Section 1(a)(xxix)(A) of this Agreement are true and correct assuming that the consummation of each of the transactions contemplated by the Acquisition Agreements was effected as of the date of this Agreement.

(l)                                     Rating of Securities. The Company has no debt securities or preferred stock that is rated by any “nationally recognized statistical rating agency” (as that term is defined by the Commission for purposes of Rule 436(g)(2) under the 1933 Act).

(b)         Officer’s Certificates.  Any certificate signed by any officer of the Company or any of its subsidiaries delivered to the Representatives or to counsel for the Underwriters shall be deemed a representation and warranty by the Company to each Underwriter as to the matters covered thereby; provided, however, any certificate signed by an officer of the Company that is delivered to counsel for the Company, and a copy of which is provided to the Representatives or counsel for the Underwriters for informational purposes only, shall not be deemed to be a representation or warranty by the Company to the Underwriters.  The Company acknowledges that the Underwriters and, for purposes of the opinions to be delivered pursuant to Section 5 hereof, counsel to the Company and counsel to the Underwriters, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance.

SECTION 2.                            Sale and Delivery to Underwriters; Closing.

(a)                                 Initial Securities.  On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, severally and not jointly, and each Underwriter, severally and not jointly, agrees to purchase from the Company, at the price per share set forth in Schedule A, that proportion of the number of Initial Securities set forth in Schedule B opposite the name of the Company, which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus any additional number of Initial Securities that such Underwriter may become obligated to purchase pursuant to the provisions of Section 10 hereof, bears to the total number of Initial Securities, subject, in each case, to such adjustments among the Underwriters as Merrill Lynch in its sole discretion shall make to eliminate any sales or purchases of fractional shares.

(b)                                 Option Securities.  In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters, severally and not jointly, to purchase up to an additional 2,250,000 shares of Common Stock, as set forth in Schedule B, at the price per share set forth in Schedule A, less an amount per share equal to any dividends or distributions declared by the Company and payable on the Initial Securities but not payable on the Option Securities.  The option hereby granted may be exercised for 30 days after the date hereof and may be exercised in whole or in part at any time from time to time upon notice by the Representatives to the Company setting forth the number of Option Securities as to which the several Underwriters are then exercising the option and the time and date of payment and delivery for such Option Securities.  Any such time and date of delivery (a “Date of Delivery”) shall be determined by the Representatives, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time.  If the option is exercised as to all or any portion of the Option Securities, each of the Underwriters, acting severally and not jointly, will purchase that proportion of the total number of Option Securities then being purchased which the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter bears to the total number of Initial Securities, subject, in each case, to such adjustments as Merrill Lynch in its sole discretion shall make to eliminate any sales or purchases of fractional shares.

15

(c)                                  Payment.  The Initial Securities shall be delivered by the Company to the Representatives, through the facilities of DTC for the account of the Representatives, against payment by the Representatives of the purchase price therefor by wire transfer of immediately available funds to a bank account designated by the Company. The closing of the transactions contemplated thereby shall occur at the offices of Goodwin Procter LLP, 620 Eighth Avenue, New York, NY 10018, or at such other place as shall be agreed upon by the Representatives and the Company, at 9:00 A.M. (New York City time) on the third (fourth, if the pricing occurs after 4:30 P.M. (New York City time) on any given day) business day after the date hereof (unless postponed in accordance with the provisions of Section 10), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Company (such time and date of payment and delivery being herein called “Closing Time”).

In addition, in the event that any or all of the Option Securities are purchased by the Underwriters, such Option Securities shall be delivered by the Company to the Representatives, through the facilities of DTC for the account of the Representatives, against payment by the Representatives of the purchase price therefor by wire transfer of immediately available funds to a bank account designated by the Company, and the closing of such Option Securities shall take place at the above-mentioned offices, or at such other place as shall be agreed upon by the Representatives and the Company, on each Date of Delivery as specified in the notice from Merrill Lynch to the Company.

It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Initial Securities and the Option Securities, if any, which it has agreed to purchase.  Merrill Lynch, individually and not as representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Initial Securities or the Option Securities, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

SECTION 3.                            Covenants of the Company.  The Company  covenants with each Underwriter as follows:

(a)                                 Compliance with Securities Regulations and Commission Requests.  The Company, subject to Section 3(b), will comply with the requirements of Rule 430B, and will notify the Representatives promptly, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective or any amendment or supplement to the Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus, including any document incorporated by reference therein or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment or of any order preventing or suspending the use of any preliminary prospectus or the Prospectus, or of the suspension of the qualification of the 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(d) or 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities.  The Company will effect all filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus.  The Company will use its reasonable efforts to prevent the issuance of any stop order, prevention or suspension and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment.  The Company shall pay the

16

required Commission filing fees relating to the Securities within the time required by Rule 456(b)(1)(i) under the 1933 Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the 1933 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)).

(b)                                 Continued Compliance with Securities Laws.  The Company will comply with the 1933 Act, the 1933 Act Regulations, the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Registration Statement, the General Disclosure Package and the Prospectus.  If at any time when a prospectus relating to the Securities is (or, but for the exception afforded by Rule 172 of the 1933 Act Regulations (“Rule 172”), would be) required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to (i) amend the Registration Statement in order that the Registration Statement will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) amend or supplement the General Disclosure Package or the Prospectus in order that the General Disclosure Package or the Prospectus, as the case may be, will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser or (iii) amend the Registration Statement or amend or supplement the General Disclosure Package or the Prospectus, as the case may be, in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly (A) give the Representatives notice of such event, (B) prepare any amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement, the General Disclosure Package or the Prospectus comply with such requirements and, a reasonable amount of time prior to any proposed filing or use, furnish the Representatives with copies of any such amendment or supplement and (C) file with the Commission any such amendment or supplement; provided that the Company shall not file or use any such amendment or supplement to which the Representatives or counsel for the Underwriters shall reasonably object.  The Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.  The Company has given the Representatives notice of any filings made pursuant to the 1934 Act or 1934 Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time to the Closing Time and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object.

(c)                                  Delivery of Registration Statements.  The Company has furnished or will deliver to the Representatives and counsel for the Underwriters, during the period beginning at the Applicable Time and ending on the later of the Closing Date, and such date as a prospectus is no longer required by law to be delivered in connection with sales by the Underwriters (including in circumstances where such requirement may be satisfied pursuant to Rule 172) (the “Delivery Period”) without charge, copies of the Registration Statement as originally filed and each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein) and copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Registration Statement as originally filed and each amendment thereto (without exhibits) as the Underwriters may reasonably request during the Delivery Period.  The copies of the Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

17

(d)                                 Delivery of Prospectuses.  The Company has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act.  The Company will furnish to each Underwriter, without charge, during the Delivery Period, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request.  The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(e)                                  Blue Sky Qualifications.  The Company will use its reasonable best efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect so long as required to complete the distribution of the Securities; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(f)                                   Rule 158.  The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as reasonably practicable an earnings statement for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(g)                                  Use of Proceeds.  The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Registration Statement, the General Disclosure Package and the Prospectus under “Use of Proceeds.”

(h)                                 Listing.  The Company will use its best efforts to effect and maintain the listing of the Securities on the NYSE MKT.

(i)                                     Restriction on Sale of Securities.  During a period of 90 days from the date of the Prospectus, the Company will not, without the prior written consent of Merrill Lynch, (i) directly or indirectly, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement under the 1933 Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of the Common Stock, whether any such swap or transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise.  The foregoing sentence shall not apply to (A) the Securities to be sold hereunder, (B) any shares of Common Stock issued by the Company upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof and referred to in the Registration Statement, the General Disclosure Package and the Prospectus, (C) any shares of Common Stock issued or options to purchase Common Stock granted pursuant to existing employee benefit plans of the Company referred to in the Registration Statement, the General Disclosure Package and the Prospectus or (D) any shares of Common Stock issued pursuant to any non-employee director stock plan or dividend reinvestment plan referred to in the Registration Statement, the General Disclosure Package and the Prospectus.  Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period the Company issues an earnings release or material news or a material event relating to the Company occurs or (2) prior to the expiration of the 90-day restricted period, the Company announces that it will issue an earnings release or becomes aware that material news or a material event will occur during the

18

16-day period beginning on the last day of the 90-day restricted period, the restrictions imposed in this clause (i) shall continue to apply until the expiration of the 18-day period beginning on the date of the issuance of the earnings release or the occurrence of the material news or material event, unless Merrill Lynch waives, in writing, such extension.

(j)                                    Reporting Requirements.  The Company, during the Delivery Period, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and 1934 Act Regulations.

(k)                                 Issuer Free Writing Prospectuses.  The Company agrees that, unless it obtains the prior written consent of the Representatives, it will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus,” or a portion thereof, required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the Representatives will be deemed to have consented to the Issuer Free Writing Prospectuses listed on Schedule D hereto and any “road show that is a written communication” within the meaning of Rule 433(d)(8)(i) that has been reviewed by the Representatives.  The Company represents that it has treated or agrees that it will treat each such free writing prospectus consented to, or deemed consented to, by the Representatives as an “issuer free writing prospectus,” as defined in Rule 433, and that it has complied and will comply with the applicable requirements of Rule 433 with respect thereto, including timely filing with the Commission where required, legending and record keeping.  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, any preliminary prospectus or the 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 existing at that subsequent time, not misleading, the Company will promptly notify the Representatives 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.

(l)                                     Qualification and Taxation as a REIT.  The Company will use its best efforts to continue to qualify for taxation as a REIT under the Code and will not take any action to revoke or otherwise terminate the Company’s REIT election, unless the Company’s board of directors determines in good faith that it is no longer in the best interests of the Company and its stockholders to be so qualified.

19

graphics, fees and expenses of any consultants engaged in connection with the road show presentations, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and the cost of aircraft and other transportation chartered in connection with the road show and (viii) the fees and expenses incurred in connection with the listing of the Securities on the NYSE MKT.

(b)                                 Termination of Agreement.  If this Agreement is terminated by the Representatives in accordance with the provisions of Section 5, Section 9(a)(i) or (iii) or Section 10 hereof, the Company shall reimburse the Underwriters for all of their out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriters.

SECTION 6.                            Indemnification.

(a)                                 Indemnification of Underwriters.  The Company agrees to indemnify and hold harmless each Underwriter, its affiliates (as such term is defined in Rule 501(b) under the 1933 Act (each, an “Affiliate”)), its selling agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

22

(i)                                     against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included (A) in any preliminary prospectus, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) or (B) in any materials or information prepared by the Company provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Securities (“Marketing Materials”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any preliminary prospectus, Issuer Free Writing Prospectus, Prospectus or in any Marketing Materials of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii)                                  against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company;

(iii)                               against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(b)                                 Indemnification of Company, Directors and Officers.  Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rule 430B, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Underwriter Information.

(c)                                  Actions against Parties; Notification.  Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially

23

prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement.  In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company.  An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party.  In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.  No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)                                 Settlement without Consent if Failure to Reimburse.  If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7.                            Contribution.  If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discount received by the Underwriters, on the other hand, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on the cover of the Prospectus.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied

24

by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7.  The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the underwriting commissions received by such Underwriter in connection with the Securities underwritten by it and distributed to the public.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Underwriter’s Affiliates and selling agents shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company  within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company.  The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial Securities set forth opposite their respective names in Schedule A hereto and not joint.

SECTION 8.                            Representations, Warranties and Agreements to Survive.  All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of any Underwriter or its Affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Company and (ii) delivery of and payment for the Securities.

SECTION 9.                            Termination of Agreement.

(a)                                 Termination.  The Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, in the judgment of the Representatives, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement (as updated by the Prospectus), the General Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the completion of the offering or to enforce contracts for the

25

sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE MKT, or (iv) if trading generally on the NYSE MKT or the New York Stock Exchange or in the Nasdaq Global Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission, FINRA or any other governmental authority, or (v) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or with respect to Clearstream or Euroclear systems in Europe, or (vi) if a banking moratorium has been declared by Federal authorities or by New York or Massachusetts authorities.

(b)                                 Liabilities.  If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7, 8, 14, 15 and 16 shall survive such termination and remain in full force and effect.

SECTION 10.                     Default by One or More of the Underwriters.  If one or more of the Underwriters shall fail at the Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i)                                     if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii)                                  if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the Underwriters to purchase, and the Company to sell, the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the Underwriters to purchase and the Company to sell the relevant Option Securities, as the case may be, either the (i) Representatives or (ii) the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement, the General Disclosure Package or the Prospectus or in any other documents or arrangements.  As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11.                     Notices.  All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.  Notices to the Underwriters shall be directed to Merrill Lynch at One Bryant Park, New York, New York 10036, attention of Syndicate Department (facsimile: (646) 855-3073), with a copy

SECTION 12.                     No Advisory or Fiduciary Relationship.  The Company acknowledges and agrees that (a) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the initial public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the several Underwriters, on the other hand, (b) in connection with the offering of the Securities and the process leading thereto, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company or any of its subsidiaries, or its respective stockholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering of the Securities or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or any of its subsidiaries on other matters) and no Underwriter has any obligation to the Company with respect to the offering of the Securities except the obligations expressly set forth in this Agreement, (d) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and the Company has consulted its own respective legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

SECTION 13.                     Parties.  This Agreement shall each inure to the benefit of and be binding upon the Underwriters and the Company and their respective successors.  Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained.  This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.  No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 14.                     Trial by Jury.  The Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

SECTION 15.                     GOVERNING LAW.  THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF, THE STATE OF NEW YORK WITHOUT REGARD TO ITS CHOICE OF LAW PROVISIONS.

Re:          Franklin Street Properties Corp.

Ladies and Gentlemen:

This letter is being furnished to you pursuant to Section 5(b) of the Underwriting Agreement, dated May 9, 2013 (the “Underwriting Agreement”), among Franklin Street Properties Corp., a Maryland corporation (the “Company”), Merrill Lynch, Pierce, Fenner & Smith Incorporated, Robert W. Baird & Co. Incorporated and BMO Capital Markets Corp. as representatives of the several Underwriters named in Schedule A thereto (each an “Underwriter” and collectively, the “Underwriters”).  Capitalized terms used herein and not otherwise defined herein shall have the respective meanings ascribed to them in the Underwriting Agreement.

We have acted as counsel for the Company in connection with the sale to the Underwriters by the Company of 15,000,000 shares (the “Shares”) of Common Stock, $0.0001 par value per share, of the Company (“Common Stock”) pursuant to the Underwriting Agreement, including 2,250,000 Shares being sold by the Company to the Underwriters pursuant to the option set forth in Section 2 of the Underwriting Agreement.  As such counsel, we have assisted in the preparation and filing with the Securities and Exchange Commission (the “Commission”) of the Company’s Registration Statement on Form S-3 (File No. 333-181009) filed by the Company

with the Commission under the Securities Act of 1933, as amended (the “1933 Act”), on April 27, 2012.  Such Registration Statement, in the form in which it became effective for purposes of Section 11 of the 1933 Act (as such section applies to the Underwriters), including the documents incorporated by reference therein or otherwise deemed to be a part thereof at the time of effectiveness pursuant to Rule 430A or Rule 430B under the 1933 Act, is referred to herein as the “Registration Statement,” and the prospectus dated April 27, 2012, forming a part of the Registration Statement, including the documents incorporated by reference therein, is referred to herein as the “Base Prospectus.”  The preliminary prospectus supplement dated May 6, 2013, including the documents incorporated by reference therein, as filed with the Commission pursuant to Rule 424(b)(5) of the 1933 Act on May 6, 2013 is referred to herein as the “Preliminary Prospectus Supplement,” and the final prospectus supplement dated May 9, 2013, including the documents incorporated by reference therein, as filed with the Commission pursuant to Rule 424(b)(5) of the 1933 Act on May [·], 2013 is referred to herein as the “Prospectus Supplement.” The Base Prospectus and the Prospectus Supplement are collectively referred to herein as the “Prospectus.”  As used herein, the term “General Disclosure Package” shall refer to the Base Prospectus, as amended and supplemented by the Preliminary Prospectus Supplement, and the other information set forth on Schedule A attached hereto, all considered together, and the term “Time of Sale” shall refer to 5:00 p.m. (Eastern Time) on the date of the Underwriting Agreement, which you have informed us is a time prior to the time of the first sale of the Shares by any Underwriter.

We have examined and relied upon the Articles of Incorporation of the Company, as amended to date (the “Articles of Incorporation”), the By-laws of the Company, as amended to date (the “By-laws”), records of meetings of stockholders and of the Board of Directors of the Company, corporate proceedings of the Company regarding the authorization of the execution and delivery of the Underwriting Agreement and the issuance of the Shares, the corporate records of the Company as provided to us by the Company, the Registration Statement, the General Disclosure Package, the Underwriting Agreement, certificates of representatives of the Company, certificates of public officials, and such other documents, instruments and certificates as we have deemed necessary as a basis for the opinions hereinafter expressed.

In our examination of the documents referred to above, we have assumed the genuineness of all signatures, the legal capacity of all individual signatories, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, the authenticity of such original documents, and the completeness and accuracy of the corporate records of the Company provided to us by the Company.

Insofar as the opinions expressed in this letter relate to factual matters, we have relied, with your permission, upon certificates, statements and representations of officers and other representatives of the Company, representations made in the Underwriting Agreement and statements contained in the Registration Statement, the General Disclosure Package and the Prospectus.  We have not

A-2

searched any electronic databases or the dockets of any court, administrative body or regulatory or governmental agency or any other filing office in any jurisdiction in connection with the preparation of this letter.

Our opinion expressed in paragraph 1 below as to the due incorporation, valid existence and good standing of the Company is based solely on a certificate of legal existence and good standing issued by the State Department of Assessments and Taxation of the State of Maryland, as set forth on Schedule B attached hereto, a copy of which has been made available to your counsel, and our opinion with respect to such matters is rendered as of the date of such certificate and limited accordingly.

Our opinion expressed in paragraph 3 below as to the due qualification and good standing of the Company as a foreign corporation is based solely on certificates of qualification and/or good standing issued by the Secretaries of State or other appropriate officials of the jurisdictions set forth on Schedule C attached hereto, copies of which have been made available to your counsel, and our opinion with respect to such matters is rendered as of the dates of such certificates and limited accordingly.  We express no opinion as to the tax good standing of the Company in any jurisdiction.

Our opinion expressed in paragraph 4 below as to valid existence and good standing of FSP Holdings LLC, FSP Investments LLC, FSP Property Management LLC and FSP Protective TRS Corp. (collectively, the “Principal Subsidiaries” and individually, a “Principal Subsidiary”) are based solely on certificates of legal existence and/or good standing, as applicable, for each Principal Subsidiary, as listed on Schedule D attached hereto, copies of which have been made available to your counsel, and our opinion with respect to such matters is rendered as of the dates of such certificates and limited accordingly. We express no opinion as to the tax good standing of any of the Principal Subsidiaries in any jurisdiction.

We express no opinion herein as to the laws of any jurisdiction other than the state laws of the State of Maryland, the state laws of the Commonwealth of Massachusetts, the statutes codified as 6 Del.C. §§ 18-101 to 1109 and known as the Limited Liability Company Act of the State of Delaware and the federal laws of the United States of America.  To the extent that any other laws govern any of the matters as to which we express an opinion herein, we have assumed for purposes of this letter, with your permission and without independent investigation, that such laws are identical to the state laws of the State of Maryland, and we express no opinion as to whether such assumption is reasonable or correct.  We note that the Underwriting Agreement states that it is governed by the laws of the State of New York.  We also express no opinion herein with respect to (i) the securities or Blue Sky laws of any state or other jurisdiction of the United States or of any foreign jurisdiction or (ii) the by-laws or any rules or other regulations of the Financial Industry Regulatory Authority, Inc.  In addition, we express no opinion and, except as set forth below in the second-to-last paragraph hereof, make no statement herein with respect to the antifraud laws of any jurisdiction.

A-3

On the basis of and subject to the foregoing, we are of the opinion that:

1.             The Company has been duly incorporated and is validly existing as a corporation in good standing under the laws of the State of Maryland.

2.             The Company has corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus and to enter into and perform its obligations under the Underwriting Agreement.

3.             The Company is duly qualified and is in good standing as a foreign corporation authorized to do business in the states listed on Schedule C attached hereto.

4.             Each of the Principal Subsidiaries is validly existing as a limited liability company or corporation, as the case may be, in good standing under the law of its jurisdiction of organization as set forth opposite its name on Schedule D attached hereto.  Each Principal Subsidiary has the limited liability company or corporate power, as the case may be, to carry on its business and to own its property as such business and property are described in the Registration Statement, the General Disclosure Package and the Prospectus and is duly qualified and in good standing as a foreign corporation authorized to do business in the states listed on Schedule D attached hereto.

5.             The Securities have been duly authorized for issuance and sale to the Underwriters pursuant to the Underwriting Agreement and, when issued and delivered by the Company pursuant to the Underwriting Agreement against payment of the consideration set forth in the Underwriting Agreement, will be validly issued and fully paid and non-assessable.

6.             The issuance of the Securities is not subject to any preemptive rights under the Maryland General Corporation Law statute, the Articles of Incorporation or the By-laws or similar contractual rights granted by the Company pursuant to any contract or agreement that is listed on Schedule E attached hereto.

7.             The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

8.             The execution and delivery of the Underwriting Agreement by the Company and the consummation by the Company of the transactions contemplated thereby will not, whether with or without the giving of notice or lapse of time or both, (a) conflict with or constitute a breach of any of the terms or provisions of, or a default under, the Articles of Incorporation or By-laws or any indenture, loan agreement, mortgage, lease or other agreement or instrument to which the Company is a party and

A-4

that is filed as an exhibit to the Registration Statement or (b) violate or conflict with any United States federal or Maryland state law, rule or regulation that in our experience is normally applicable in transactions of the type contemplated by the Underwriting Agreement, or any judgment, order or decree specifically naming the Company of which we are aware.

9.             The Registration Statement has been declared effective by the Commission under the 1933 Act and the rules and regulations of the Commission thereunder.  The Prospectus Supplement has been filed with the Commission in the manner and within the time period required by Rule 424(b) (without reference to Rule 424(b)(8)).  To our knowledge, (a) no stop order suspending the effectiveness of the Registration Statement has been issued under the 1933 Act and (b) no proceedings for any such purpose have been instituted or are pending or threatened by the Commission.

10.          Except as may be required under the 1933 Act, the 1934 Act and the rules and regulations of the Commission under the 1933 Act and 1934 Act, no filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any United States federal or Maryland state governmental authority or agency is necessary in connection with the authorization, execution and delivery of the Underwriting Agreement or the offering, issuance, sale or delivery of the Securities.

11.          The statements in the Prospectus under the caption “Description of Capital Stock,” insofar as such statements constitute matters of law or legal conclusions or summarize the terms of agreements are correct in all material respects.

12.          The authorized capital stock of the Company consists of 180,000,000 shares of Common Stock, par value $0.0001 per share, and 20,000,000 shares of Preferred Stock, par value $0.0001 per share.

13.          Except as described in the Registration Statement, the General Disclosure Package and the Prospectus, no contract or agreement that has been filed as an exhibit to the Registration Statement grants any person a right to require the Company to register pursuant to the Registration Statement any securities other than the Securities, except for any such right as has been waived.

14.          The Company is not, and after giving effect to the issuance and sale of the Securities and the application of the net proceeds therefrom as described in the Prospectus will not be, an “investment company” under the 1940 Act.

The foregoing opinions are provided to you, as the Underwriters, as a legal opinion only and not as a guaranty or warranty of the matters discussed herein.  These opinions are based upon currently existing statutes, rules, regulations and judicial decisions and are rendered as of the

A-5

date hereof, and we disclaim any obligation to advise you of any change in any of the foregoing sources of law or subsequent developments in law or changes in facts or circumstances that might affect any matters or opinions set forth herein.

In addition to the opinions provided above, we confirm to you as follows:  In the course of acting as counsel for the Company in connection with the preparation of the Registration Statement, the General Disclosure Package and the Prospectus, we have participated in conferences with officers and other representatives of the Company, representatives of and counsel for the Underwriters and representatives of the registered independent public accounting firm of the Company, during which the contents of the Registration Statement, the General Disclosure Package and the Prospectus were discussed.  While the limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such that we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus (except to the extent expressly set forth in opinion 11 above), subject to the foregoing and based on such participation and discussions:

(a)                                 the Registration Statement, as of the date of its filing with the Commission, and the Prospectus, as of the date thereof (except for the financial statements, including the notes and schedules thereto, other financial and accounting data included therein or omitted therefrom, and assessments of or reports on the effectiveness of internal control over financial reporting contained therein, as to which we express no view), appear on their face to be appropriately responsive in all material respects to the requirements of the 1933 Act and the applicable rules and regulations of the Commission thereunder;

(b)                                 no facts have come to our attention that have caused us to believe that (i) any part of the Registration Statement, when such part becomes effective, 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 (except as set forth in the parenthetical in clause (a) above), (ii) the General Disclosure Package, as of the Time of Sale, 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 the circumstances under which they were made, not misleading (except as set forth in the parenthetical in clause (a) above) or (iii) the Prospectus as of its date or as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (except as set forth in the parenthetical in clause (a) above);

(c)                                  we are not aware of any contract or other document of a character required by the 1933 Act and the rules and regulations of the Commission thereunder to be filed as an exhibit to the Registration Statement that is not so filed; and

A-6

(d)                                 we are not aware of any action, proceeding or litigation pending or threatened against the Company before any court or governmental or administrative agency or body that is required by the 1933 Act or the rules and regulations of the Commission thereunder to be described in the Registration Statement or the Prospectus that is not so described.

This letter is rendered only to you, as the representatives of the Underwriters, and is solely for the benefit of the Underwriters in connection with the transactions contemplated by the Underwriting Agreement.  This letter may not be relied upon by the Underwriters for any other purpose, nor may this letter be provided to, quoted to or relied upon by any other person or entity.

Very truly yours,

Re:                             Certain Federal Income Tax Matters Related to Franklin Street Properties Corp.

Dear Ladies and Gentlemen:

This opinion is being delivered to you pursuant to Section 5(c) of the Underwriting Agreement dated May 9, 2013 (the “Underwriting Agreement”), among Franklin Street Properties Corp., a Maryland corporation (“FSP Corp.”), Merrill Lynch, Pierce, Fenner & Smith Incorporated, Robert W. Baird & Co. Incorporated and BMO Capital Markets Corp. as representatives of the several Underwriters named in Schedule A thereto.

  Except as otherwise provided, capitalized terms not defined herein have the meanings set forth in the letter delivered to Wilmer Cutler Pickering Hale and Dorr LLP by FSP Corp. containing certain representations of FSP Corp. relevant to this opinion (the “Representation Letter”), a copy of which has been provided to you for informational purposes only.  All section references, unless otherwise indicated, are to the United States Internal Revenue Code of 1986, as amended (the “Code”).

The conclusions expressed herein represent our judgment as to the proper application of relevant provisions of the Code, Treasury Regulations, case law, and rulings and other pronouncements of the Internal Revenue Service (the “IRS”) as in effect on the date of this opinion.  No assurances can be given that such laws will not be amended or otherwise changed, or that such changes will not affect the conclusions expressed herein.  Nevertheless, we undertake no responsibility to advise you of any developments in the application or interpretation of the income tax laws of the United States.

B-1

Our opinion represents our best judgment of how a court would decide if presented with the issues addressed herein and is not binding upon either the IRS or any court.  Thus, no assurances can be given that a position taken in reliance on our opinion will not be challenged by the IRS or rejected by a court.

In our capacity as counsel to FSP Corp., and for purposes of rendering this opinion, we have examined and relied upon the Registration Statement of FSP Corp., filed with the Securities and Exchange Commission (the “Commission”) on Form S-3 on April 27, 2012 (the “Registration Statement”), the prospectus dated April 27, 2012 forming a part of the Registration Statement, the prospectus supplements dated May 6, 2013 and May [  ], 2013 (the “Prospectus Supplements”), as filed with the Commission, the Representation Letter, the Articles of Incorporation of FSP Corp. and the By-Laws of FSP Corp., each as amended through the date hereof, and such other documents as we considered relevant to our analysis.  In our examination of documents, we have assumed the authenticity of original documents, the accuracy of copies, the genuineness of signatures, and the legal capacity of signatories.

We have made such factual and legal inquiries, including examination of the documents set forth above, as we have deemed necessary or appropriate for purposes of our opinion.  For purposes of rendering our opinion, however, we have not made an independent investigation or audit of the facts set forth in any of the above-referenced documents, including the Registration Statement, the Prospectus Supplements and the Representation Letter.  We consequently have relied upon the representations contained therein and assumed that the information presented in such documents or otherwise furnished to us is accurate and complete in all respects relevant to our opinion.

In our review, we have assumed, with your consent, that all of the obligations imposed by any documents on the parties thereto have been and will be performed or satisfied substantially in accordance with their terms.  We have further assumed that during its taxable year ended December 31, 2002 and subsequent taxable years that FSP Corp. and the Partnership Subsidiaries have operated and will continue to operate in a manner that has made and will make the representations and covenants contained in the Representation Letter true, complete and correct for all such years.  Moreover, we have assumed that FSP Corp. and the Partnership Subsidiaries have been and will continue to be operated in the manner described in the relevant partnership agreement, articles (or certificate) of incorporation or other organizational documents, and in the Registration Statement and the Prospectus Supplements.  Finally, we have assumed that any statement in the Representation Letter that is made “to the knowledge of,” “belief of” or similarly qualified is correct and accurate, and that such representation or statement will continue to be correct and accurate without such qualification.

We also have assumed for the purposes of this opinion, without inquiry with respect thereto, that FSP Corp. is a validly organized and duly incorporated corporation under the laws of the State of Maryland.  In the event any of the statements, representations, or assumptions upon which we have relied in rendering this opinion is incorrect or incomplete, our opinion could be adversely affected and may not be relied upon.

Opinion

Based upon the foregoing, and subject to the various assumptions, limitations, and qualifications set forth in this letter, we are of the opinion that FSP Corp. qualified to be taxed as a REIT pursuant to sections 856 through 860 of the Code for its taxable years ended December 31, 2002 through December 31, 2012, and FSP Corp.’s organization, ownership and proposed method of operation as described in the Registration Statement, the Prospectus Supplements and the Representation Letter will enable it to continue to qualify as a REIT for its taxable year ending December 31, 2013, and in the future.

B-2

FSP Corp.’s qualification and taxation as a REIT depends upon FSP Corp.’s ability to meet on a continuing basis, through actual annual operating and other results, the various requirements under the Code as described in the Prospectus Supplements with regard to, among other things, the sources of its gross income, the composition of its assets, the level of distributions to stockholders, and the diversity of its share ownership.  Wilmer Cutler Pickering Hale and Dorr LLP will not review FSP Corp.’s compliance with these requirements on an independent or ongoing basis.  No assurance can be given that the actual results of operations of FSP Corp., the sources of its income, the nature of its assets, the level of FSP Corp.’s distributions to its shareholders and the diversity of FSP Corp.’s share ownership for any given taxable year will satisfy the requirements under the Code for qualification and taxation as a REIT or that the relief provisions applicable to REITs will be available to FSP Corp.

This opinion addresses only the specific United States federal income tax consequences set forth above under the caption “Opinion” and does not address any other federal, state, local, or foreign income, estate, gift, transfer, sales, use, or other tax consequences that may be applicable to FSP Corp.

This letter is rendered only to you, solely for your benefit in connection with the transactions contemplated by the Underwriting Agreement.  This letter may not be relied upon by you for any other purpose, nor may this letter be provided to, quoted to or relied upon by any other person or entity.  This opinion speaks only as of the date hereof, and we undertake no obligation to update or supplement this opinion to reflect any changes of law or fact (including without limitation our subsequent discovery of any facts that are inconsistent with the Representation Letter).

IRS CIRCULAR 230 DISCLOSURE:

                To ensure compliance with requirements imposed by the Internal Revenue Service, we inform you that:  (i) any United States tax advice contained in this opinion is not intended or written to be used, and cannot be used, for the purpose of avoiding penalties under the Code; (ii) this opinion was written to support the promotion or marketing of the offering and sale of shares of FSP Corp.; and (iii) you should seek advice based on your particular circumstances from independent tax advisors.

The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Lock-Up Securities except in compliance with the foregoing restrictions.
