SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Transaction Entities. Each of the Transaction Entities, jointly and severally, represents and warrants to each Underwriter as of the date hereof, the Applicable Time, the Closing Time (as defined below) and any Date of Delivery (as defined below), and agrees with each Underwriter, as follows:

(i) Registration Statement and Prospectuses. The Company has prepared and filed with the Commission a registration statement on Form S-3 (File No. 333-193203) under the 1933 Act on January 6, 2014, which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of the Securities. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto in the form in which it was declared effective by the Commission under the 1933 Act, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the regulations of the 1933 Act (“Rule 430B”) or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “1934 Act”), is called the “Registration Statement.” Any registration statement filed by the Company pursuant to Rule 462(b) under the 1933 Act is called the “Rule 462(b) Registration Statement,” and from and after the date and time of filing of the Rule 462(b) Registration Statement the term “Registration Statement” shall include the Rule 462(b) Registration Statement. Any preliminary prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof and is used prior to filing of the Prospectus is called, together with the Base Prospectus, a “preliminary prospectus.” The term “Prospectus” shall mean the final prospectus supplement relating to the Securities and the Base Prospectus in the form first furnished (electronically or otherwise) to the Underwriters for use in connection with the offering of the Securities (whether to meet requests of the purchasers pursuant to Rule 173 under the 1933 Act or otherwise) or, if not furnished to the Underwriters, in the form first filed by the Company with the Commission pursuant to Rule 424(b) under the 1933 Act after the date and time that this Agreement is executed and delivered by the parties hereto (the “Execution Time”). Any reference herein to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act; any reference to any amendment or supplement to any preliminary prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such preliminary prospectus or Prospectus, as the case may be, under the 1934 Act, and incorporated by reference in such preliminary prospectus or Prospectus, as the case may be; and any reference to any amendment to the Registration Statement shall be deemed to refer to and include any annual report of the Company filed pursuant to Section 13(a) or 15(d) of the 1934 Act after the effective date of the Registration Statement that is incorporated by reference in the Registration Statement. 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”).

(ii) Compliance with Registration Requirements. The Registration Statement has been declared effective by the Commission under the 1933 Act. The Company has complied to the Commission’s satisfaction with all requests of the Commission for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement is in effect, the Commission has not issued any order or notice preventing or suspending the use of the Registration Statement, any preliminary prospectus or the Prospectus and no proceedings for such purpose have been instituted or are pending or, to the best knowledge of the Company, are contemplated or threatened by the Commission.

Each preliminary prospectus and the Prospectus when filed complied in all material respects with the 1933 Act and the rules thereunder. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective and at the date hereof, complied

and will comply in all material respects with the 1933 Act and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. The Prospectus, as of its date, at the date hereof, at the time of any filing pursuant to Rule 424(b) under the 1933 Act, at the Closing Time (as defined herein), did not and will not contain any untrue statement of a material fact or 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 representations and warranties set forth in the two immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with the Underwriter Information (as defined herein). There is no contract or other document required to be described in the Registration Statement or Prospectus or to be filed as an exhibit to the Registration Statement that has not been described or filed as required. For purposes of this Agreement, “Underwriter Information” shall be the information in the first paragraph under the heading “Underwriting–Commissions and Discounts” and the information in the second and third paragraphs under the heading “Underwriting–Price Stabilization, Short Positions” in each case contained in the Prospectus.

(iii) Incorporation by Reference in the Prospectus. The documents incorporated or deemed to be incorporated by reference in the Prospectus, when they were filed with the Commission or became effective, as the case may be, conformed in all material respects with the requirements of the 1933 Act or the 1934 Act, as applicable. Any further documents so filed and incorporated by reference in the Prospectus and any further amendments or supplements thereto will conform in all material respects with the requirements of the 1933 Act or the 1934 Act and the rules and regulations thereunder, as applicable, and will not contain 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.

(iv) General Disclosure Package. As of Applicable Time, neither the General Disclosure Package or any Issuer Limited Use Free Writing Prospectus, when considered together with the General Disclosure Package, contained any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the General Disclosure Package made in reliance upon and in conformity with the Underwriters Information furnished to the Company in writing by the Underwriters expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriters consists of the Underwriter Information.

(v) Accuracy of Statements in Prospectus. The statements in the General Disclosure Package and the Prospectus under the headings “Description of Capital Stock,” “Description of Common Stock,” “Material Provisions of Maryland Law and of our Charter and Bylaws,” “Material U.S. Federal Income Tax Considerations,” and “Underwriting” (other than the Underwriter Information), insofar as such statements summarize legal matters, agreements, documents or proceedings discussed therein, are accurate summaries of such legal matters, agreements, documents or proceedings.

(vi) Distribution of Offering Material by the Transaction Entities. Neither of the Transaction Entities has distributed or will distribute, prior to the Closing Time (as defined below), any offering material in connection with the offering and sale of the Securities other than a preliminary prospectus, the Prospectus, any Issuer Free Writing Prospectus reviewed and consented to by the Underwriters or included in Schedule C-2 hereto or the Registration Statement.

(vii) The Underwriting Agreement. This Agreement has been duly authorized, executed and delivered by the each of Transaction Entities.

(viii) No Transfer Taxes. There are no transfer taxes or other similar fees or charges under federal law or the laws of any state, or any political subdivision thereof, or any other U.S. or non-U.S. governmental authority required to be paid in connection with the execution and delivery of this Agreement or the issuance by the Company or sale by the Company of the Securities.

(ix) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering of Securities under this Agreement or until any earlier date that the Company notified or notifies the Representatives as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained or incorporated by reference in the Registration Statement, including any prospectus or prospectus supplement that is or becomes part of the Registration Statement. 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 or incorporated by reference in the Registration Statement, the Company has promptly notified or will promptly notify the Representatives and has promptly amended or supplemented or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with the Underwriters Information.

(x) Company Not Ineligible Issuer. At the earliest time after the filing of the Registration Statement relating to the Securities that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the 1933 Act and (ii) as of the date of the execution and delivery of this Agreement (with such date being used as the determination date for purposes of this clause (ii)), the Company was not and is not an “ineligible issuer” (as defined in Rule 405 of the 1933 Act), without taking account of any determination by the Commission pursuant to Rule 405 of the Securities Act that it is not necessary that the Company be considered an ineligible issuer.

(xi) Independent Accountants. The accountants who certified the financial statements, the related notes thereto and supporting schedules included in the Registration Statement, the General Disclosure Package and the Prospectus are independent public accountants with respect to the Company and, to the Company’s knowledge, Thomas Properties Group, Inc. as required by the 1933 Act, the 1933 Act Regulations, the 1934 Act, the regulations promulgated under the 1934 Act (the “1934 Act Regulations”) and the Public Accounting Oversight Board.

(“FINRA”). As used herein, a “Debt Repayment Triggering Event” means any event or condition which gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by the Transaction Entities or any of the Subsidiaries.

(xxv) Labor Matters.

(xxviii) ERISA. The Company and each of its subsidiaries is in compliance with all applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”), except where such non-compliance would not have a Material Adverse Effect; no “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company or any of its subsidiaries would have any liability that would result in a Material Adverse Effect; neither the Company nor any subsidiary has incurred or expects to incur liability that would result in a Material Adverse Effect under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended (the “Code”); each “pension plan” for which the

Company or any subsidiary would have any liability that would result in a Material Adverse Effect that is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service that such plan is so qualified in all material respects and, to the knowledge of the Company, nothing has occurred thereunder, whether by action or by failure to act, which would cause the loss of such qualification, except where the failure to be so qualified would not have a Material Adverse Effect.

(xxx) No Finder’s Fee. Except as described in the General Disclosure Package and the Prospectus, there are no contracts, agreements or understandings between or among the Transaction Entities or any of the Subsidiaries and any person that would give rise to a valid claim against the Transaction Entities, any of the Subsidiaries or the Underwriters for a brokerage commission, finder’s fee or other like payment in connection with the offering, issuance and sale of the Securities.

(xxxi) Licenses, Certificates and Permits. Each of the Transaction Entities and the Subsidiaries holds all material licenses, certificates and permits from governmental authorities which are necessary to the conduct of its business and is in compliance with the terms and conditions of such licenses, certificates and permits, except where the failure to do so would not, singly or in the aggregate, result in a Material Adverse Effect; and none of the Transaction Entities or any of the Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such permits, licenses or certificates that, if determined adversely to the Transaction Entities or any Subsidiary, would, individually or in the aggregate, have a Material Adverse Effect.

(xxxii) Title to Property. Each of the Transaction Entities and the Subsidiaries has good and marketable title to the properties and assets, as described in the General Disclosure Package and the Prospectus (the “Properties”), owned by it, free and clear of all liens, charges, encumbrances or restrictions, except such as are described in the General Disclosure Package and the Prospectus or are not material in relation to the business of the Transaction Entities and the Subsidiaries on a consolidated basis. Each of the Transaction Entities and the Subsidiaries has valid, subsisting and enforceable leases for the Properties leased by it, if any, material to the business of the Transaction Entities and the Subsidiaries, considered as one enterprise, with such exceptions as are not material and do not materially interfere with the use made and proposed to be made of such properties by it. Neither the Transaction Entitles nor any Subsidiary has any written notice of any material claim of any sort that has been asserted by anyone adverse to the rights of the Transaction Entities or any Subsidiary under any of the leases mentioned above, or threatening the rights of the Transaction Entities or any Subsidiary to the continued possession of the leased or subleased premises under any such lease or sublease. No tenant under any of the leases pursuant to which the Transaction Entities or any of the Subsidiaries leases the Properties has an option or right of first refusal to purchase the premises demised under such lease. The use and occupancy of each of the Properties comply with all applicable codes and zoning laws and regulations, except where the failure to do so would not, singly or in the aggregate, result in a Material Adverse Effect; and none of the Transaction Entities or the Subsidiaries has knowledge of any pending or threatened proceeding or action that will in any manner materially affect the size of, use of, improvements or construction on, or access to any of the Properties.

(xxxiii) No Conversion into Equity. The mortgages and deeds of trust encumbering the properties and assets described or referred to in the General Disclosure Package and the Prospectus are not convertible into the equity of the Company or any Subsidiary.

To the knowledge of the Transaction Entities, water, storm water, sanitary sewer, electricity and telephone service are all available at the property lines of each Property over duly dedicated streets or perpetual easements of record benefiting the applicable Property, except where the unavailability of such water, sanitary sewer, electricity and telephone service would not, individually or in the aggregate, materially interfere with the use made and proposed to be made of such Property.

(xxxv) Intellectual Property Rights.

In the ordinary course of its business, each of the Transaction Entities and the Subsidiaries conducts Phase I environmental assessments on each of its properties at the time such property is acquired and periodic reviews of the effect of Environmental Laws on the business, operations and properties of each of the Transaction Entities and the Subsidiaries.

(xxxvii) Internal Controls and Procedures. The Transaction Entities and the Subsidiaries maintain (i) effective internal control over financial reporting as defined in Rule 13a-15 under the 1934 Act, and (ii) a system of internal accounting controls sufficient to provide reasonable assurance that (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (E) the interactive data in eXtensible Business Reporting Language incorporated by reference in the Registration Statement, the General Disclosure Package and the Prospectus fairly presents the information called for in all material respects and is prepared in accordance with the Commission’s rules and guidelines applicable thereto.

(xxxviii) No Material Weakness in Internal Controls. Except as disclosed in the General Disclosure Package and the Prospectus, or in any document incorporated by reference therein, since the end of the Company’s and, to the Company’s knowledge, Thomas Properties Group, Inc.’s most recent audited fiscal year, there has been (i) no material weakness in the Company’s or Thomas Properties Group, Inc.’s internal control over financial reporting (whether or not remediated) and (ii) no change in the Company’s or Thomas Properties Group, Inc.’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s or Thomas Properties Group, Inc.’s internal control over financial reporting.

(xxxix) Disclosure Controls. The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 under the 1934 Act) that (i) are designed to ensure that material information relating to the Transaction Entities and the Subsidiaries is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the 1934 Act are being prepared, (ii) have been evaluated for effectiveness as of the end of the period covered by the Company’s most recent annual or quarterly report filed with the Commission and (iii) are effective in all material respects to perform the functions for which they were established. Based on the evaluation of the Company’s disclosure controls and procedures described above, the Company is not aware of (a) any significant deficiency in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize and report financial data or any material weaknesses in internal controls or (b) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal controls. Since the most recent evaluation of the Company’s disclosure controls and procedures described above, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls.

(xl) Tax Matters. All material United States federal income tax returns of the Transaction Entities and their subsidiaries required by law to be filed have been filed in a timely manner, and all such tax returns are correct and complete in all material respects and all taxes shown by such returns or otherwise due and payable have been paid, except taxes and assessments against which appeals have been or will be promptly taken and as to which adequate reserves have been provided. Each of the Transaction Entities and each of their subsidiaries has filed in a timely manner all tax returns that are required to have been filed by them pursuant to applicable foreign, state, local or other law (other than United States federal income tax law), except insofar as the failure to file such returns would not result in a Material Adverse Effect, and all such tax returns are correct and complete in all material respects. Each of the Transaction Entities and each of their subsidiaries has paid all material taxes (other than United States federal income taxes) due, except for such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided. The charges, accruals, and reserves on the books of the Company in respect of taxes for any years not finally determined are adequate to meet any assessments or re-assessments for additional tax for any years not finally determined, except to the extent of any inadequacy that would not result in a Material Adverse Effect. No tax deficiency has been asserted against the Transaction Entities or any of their subsidiaries, nor do the Transaction Entities know of any tax deficiency which is likely to be asserted against the Transaction Entities or any of their subsidiaries, except to the extent of any deficiency that would not result in a Material Adverse Effect.

(xlv) Absence of Manipulation. The Company has not taken, nor will it take, directly or indirectly, any action designed to or that might reasonably be expected to cause or result in, or which has constituted or which might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company, to facilitate the sale or resale of any of the Securities.

(xlvi) No Unlawful Contributions or Other Payments.

whether as underwriter, advisor, investor or otherwise) of Sanctions. For the past five years, the Transaction Entities and their subsidiaries have not knowingly engaged in, are not now knowingly engaged in, and will not engage in, any dealings or transactions with any person that at the time of the dealing or transaction is or was the subject or the target of Sanctions or with any Sanctioned Country.

Except as disclosed in the General Disclosure Package and the Prospectus, neither of the Transaction Entities (i) has any material lending or other relationship with any bank or lending affiliate of any Underwriter and (ii) intends to use any of the proceeds from the sale of the Securities to repay any outstanding debt owed to any affiliate of any Underwriter.

(l) Disclosure of Related Party Transactions. No transaction has occurred between or among the Transaction Entities or any Subsidiaries, on one hand, and any of their officers or directors or any affiliate or affiliates of any such officer or director, on the other hand, that is required to be described in and is not described or incorporated by reference in the Registration Statement and the Prospectus.

(li) Sarbanes-Oxley Compliance. Other than late Section 16 filings, there is and has been no failure on the part of the Company and any of the Company’s directors or officers, in their capacities as such, to comply with any provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the “Sarbanes-Oxley Act”), including Section 402 related to loans and Sections 302 and 906 related to certifications.

(lii) Statistical and Market-Related Data. Nothing has come to the attention of the Transaction Entities that has caused the Transaction Entities to believe that the statistical and market-related data included in the General Disclosure Package and the Prospectus is not based on or derived from sources that are reliable and accurate in all material respects.

(liii) NYSE Compliance. The Company is in compliance with the rules and regulations of the NYSE, including without limitation, the requirements for continued listing of the Common Stock on the NYSE; and there are no actions, suits or proceedings pending, threatened or, to the Company’s knowledge, contemplated, and the Company has not received any notice from the NYSE, regarding the revocation of such or otherwise regarding the delisting of the Common Stock from the NYSE.

(liv) Real Estate Investment Trust. For its taxable years ended December 31, 1997 through December 31, 2013, the Company has continuously been organized and has operated in conformity with the requirements for qualification as a “real estate investment trust” (a “REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s current and proposed organization and method of operation will permit it to meet and to continue to meet the requirements for taxation as a REIT under the Code for its taxable year ending December 31, 2014 and thereafter. The Company has no intention of changing its operations or engaging in activities which would cause it to fail to qualify, or make economically undesirable its continued qualification, as a REIT. All statements regarding the Company’s qualification and taxation as a REIT and descriptions of the Company’s organization and proposed method of operation (inasmuch as they relate to the Company’s qualification and taxation as a REIT) set forth in the Registration Statement, the General Disclosure Package and the Prospectus are accurate and fair summaries of the legal or tax matters described therein in all material respects.

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 is equal to (i) the number of Initial Securities set forth in Schedule A opposite the name of such Underwriter, plus (ii) 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 the Representatives in their 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 1,650,000 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 five 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 the Representatives in their sole discretion shall make to eliminate any sales or purchases of fractional shares.

(c) Payment. Payment of the purchase price for, and delivery of certificates for, the Initial Securities shall be made at the offices of Latham & Watkins LLP, 811 Main Street, Suite 3700, Houston, TX 77002, 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, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made 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 the Representatives to the Company.

Payment shall be made to the Company by wire transfer of immediately available funds to a bank account(s) designated by the Company against delivery to the Representatives for the respective accounts of the Underwriters of certificates for the Securities to be purchased by them. 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 such Underwriter has agreed to purchase. Each of the Representatives, 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.

(d) Delivery of Prospectuses. The Company has delivered to each Underwriter during the Delivery Period, 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 shall cooperate with the Underwriters to qualify or register 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 as a foreign corporation as a result of the offering or sale of the Securities or to take any action that would subject it to general service of process in any jurisdiction in which it is not otherwise so subject.

(i) Restriction on Sale of Securities. During a period of 60 days from the date of the Prospectus, the Company will not, without the prior written consent of Merrill Lynch and Wells Fargo, (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, (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 or (E) Common Stock issuable upon redemption of the Units. Notwithstanding the foregoing, if (1) during the last 17 days of the 60-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 60-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 16-day period beginning on the last day of the 60-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 the Representatives waive, in writing, such extension.

(j) Reporting Requirements. The Company, during the period when a Prospectus relating to the Securities is (or, but for the exception afforded by Rule 172, would be) required to be delivered under the 1933 Act, 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 C-2 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) Absence of Manipulation. Except as contemplated herein or in the General Disclosure Package and the Prospectus, neither Transaction Entity will take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Securities.

(m) Qualification and Taxation as a REIT. The Company will use its best efforts to meet the requirements for qualification and taxation as a REIT under the Code for its taxable year ending December 31, 2014, and the Company will use its best efforts to continue to qualify for taxation as a REIT under the Code unless and until 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.

SECTION 5. Conditions of Underwriters’ Obligations. The obligations of the several Underwriters hereunder are subject to the accuracy of the representations and warranties of the Transaction Entities contained herein or in certificates of any officer of the Transaction Entities or any of their subsidiaries delivered pursuant to the provisions hereof, to the performance by the Transaction Entities of their respective covenants and other obligations hereunder, and to the following further conditions:

(a) Effectiveness of Registration Statement. The Registration Statement has become effective and, at the Closing Time, 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 no proceedings for any of those purposes have been instituted or are pending or, to the Company’s knowledge, contemplated; and the Company has complied with each request (if any) from the Commission for additional information. 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.

(b) Opinion of Counsel for Company. At the Closing Time, the Representatives shall have received the favorable opinion, dated the Closing Time, of Hogan Lovells US LLP, counsel for the Company, in form and substance reasonably satisfactory to counsel for the Underwriters, together with signed or reproduced copies of such letter for each of the other Underwriters to the effect set forth in Exhibits A-1 hereto and to such further effect as counsel to the Underwriters may reasonably request.

In giving such opinion such counsel may rely, as to all matters governed by the laws of jurisdictions other than the law of the State of New York, the General Corporation Law of the State of Maryland and the General Corporation Law of the State of Delaware and the federal securities laws of the United States, upon the opinions of counsel satisfactory to the Representatives. Such counsel may also state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers and other representatives of the Company and its subsidiaries and certificates of public officials.

(f) Officers’ Certificate. At the Closing Time, there shall not have been, since the date hereof or since the respective dates as of which information is given in the Registration Statement, 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, and the Representatives shall have received a certificate of the Chief Executive Officer or the President of the each of the Transaction Entities and of the chief financial or chief accounting officer of each of the Transaction Entities, dated the Closing Time, to the effect that (i) there has been no such material adverse change, (ii) the representations and warranties of the Transaction Entities in this Agreement are true and correct with the same force and effect as though expressly made at and as of the Closing Time, (iii) the Transaction Entities have complied with all agreements and satisfied all conditions on their part to be performed or satisfied at or prior to the Closing Time, and (iv) no stop order suspending the effectiveness of the Registration Statement under the 1933 Act has been issued, no order preventing or suspending the use of any preliminary prospectus or the Prospectus has been issued and no proceedings for any of those purposes have been instituted or are pending or, to their knowledge, threatened by the Commission.

(h) Bring-down Comfort Letter. At the Closing Time, the Representatives shall have received letters from KPMG LLP and Ernst & Young LLP (in the case of Ernst & Young LLP, with respect to each of the Company and its consolidated subsidiaries and Thomas Properties Group, Inc., and its consolidated subsidiaries), dated as of the Closing Time, to the effect that they reaffirm the statements made in their respective letters furnished pursuant to subsection (e) of this Section, except that the specified date referred to shall be a date not more than three business days prior to the Closing Time.

(m) Conditions to Purchase of Option Securities. In the event that the Underwriters exercise their option provided in Section 2(b) hereof to purchase all or any portion of the Option Securities, the representations and warranties of the Transaction Entities contained herein and the statements in any certificates furnished by the Transaction Entities and any of their subsidiaries hereunder shall be true and correct as of each Date of Delivery and, at the relevant Date of Delivery, the Representatives shall have received:

A certificate, dated such Date of Delivery, of the President or a Vice President of each of the Transaction Entities and of the chief financial or chief accounting officer of each of the Transaction Entities confirming that the certificate delivered at the Closing Time pursuant to Section 5(e) hereof remains true and correct as of such Date of Delivery.

(o) Termination of Agreement. If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement, or, in the case of any condition to the purchase of Option Securities on a Date of Delivery which is after the Closing Time, the obligations of the several Underwriters to purchase the relevant Option Securities, may be terminated by the Representatives by notice to the Company at any time at or prior to Closing Time or such Date of Delivery, as the case may be, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 6, 7, 8, 14, 15 and 16 shall survive any such termination and remain in full force and effect.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Transaction Entities jointly and severally agree 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:

(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 and 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, in each case, 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 the Representatives), 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, in each case, 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 agrees severally 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 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 the Representatives, 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 Transaction Entities, 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 Transaction Entities, 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 Transaction Entities, 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 Transaction Entities, 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 by the Transaction Entities or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Transaction Entities 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 Transaction Entities, each officer of any Transaction Entity who signed the Registration Statement, and each person, if any, who controls any Transaction Entity 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 Transaction Entities. 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 Transaction Entities or any of their 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, 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 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 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 New York Stock Exchange, or (iv) if trading generally on the NYSE Amex 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 either Federal or New York 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 the Representatives at Merrill Lynch, Pierce, Fenner & Smith Incorporated at One Bryant Park, New York, New York 10036, attention of Syndicate Department (facsimile: (646) ###-###-####), with a copy to ECM Legal (facsimile: (212) ###-###-####); Wells Fargo Securities, LLC at 375 Park Avenue, New York, New York 10152, Attention: Equity Syndicate Department (fax no: (212) ###-###-####); J.P.

SECTION 12. No Advisory or Fiduciary Relationship. Each of the Transaction Entities 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 Transaction Entities, on the one hand, 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 Transaction Entities, any of their subsidiaries or their respective equityholders, creditors, employees or any other party, (c) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Transaction Entities 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 Transaction Entities 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 each of the Transaction Entities, and (e) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and each of the Transaction Entities 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, the Transaction Entities 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, the Transaction Entities 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, the Transaction Entities 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. Each of the Transaction Entities (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.

SECTION 16. Consent to Jurisdiction; Waiver of Immunity. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) shall be instituted in (i) the federal courts of the United States of America located in the City and County of New York, Borough of Manhattan or (ii) the courts of the State of New York located in the City and County of New York, Borough of Manhattan (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any such court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

SECTION 17. TIME. TIME SHALL BE OF THE ESSENCE OF THIS AGREEMENT. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 18. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

SECTION 19. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriters and the Transaction Entities in accordance with its terms.
