The execution, delivery and performance of this Agreement by the Investor, the purchase of the Shares in accordance with its terms and the consummation by the Investor of the other transactions contemplated hereby will not conflict with or result in any violation of, breach or default by such Investor (with or without notice or lapse of time, or both) under, conflict with, or give rise to a right of termination, cancellation or acceleration of any obligation, a change of control right or to a loss of a material benefit under (i) any provision of the organizational documents of the Investor, including, without limitation, its incorporation or formation papers, bylaws, indenture of trust or partnership or operating agreement, as may be applicable or (ii) any agreement or instrument, undertaking, credit facility, franchise, license, judgment, order, ruling, statute, law, ordinance, rule or regulations, applicable to such Investor or its respective properties or assets, except, in the case of clause (ii), as would not, individually or in the aggregate, be reasonably expected to materially delay or hinder the ability of the Investor to perform its obligations under this Agreement. 4.4 [Reserved] 4.5 Brokers and Finders.

The Investor understands that nothing in this Agreement or any other materials presented by or on behalf of the Company to the Investor in connection with the purchase of the Shares constitutes legal, tax or investment advice. The Investor has consulted such legal, tax and investment advisors as it, in such Investor’s sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares. 4.10 Access to Information. In making its decision to purchase the Shares, such Investor has had the opportunity to review the Transaction Documents and the SEC Reports and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Shares and the merits and risks of investing in the Shares; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment.

Such Investor also acknowledges that each of the Company and the Placement Agent may possess material

18 non-public information not known to such Investor regarding or relating to the Company or the Shares, and such Investor acknowledges that it has not requested such information and agrees that neither the Company nor the Placement Agent shall have any liability whatsoever (and such Investor hereby waives and releases all claims which it would otherwise have) with respect to the non-disclosure of such information either prior to the date hereof or subsequent hereto.

Other than to other Persons party to this Agreement and to its advisors and agents who had a need to know such information, the Investor has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).

For the avoidance of doubt, nothing in this Agreement shall be construed to prohibit or restrict the Investors or their respective affiliates from trading in the Company’s securities to the extent permitted by applicable law. 5.

The titles, subtitles and headings in this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement. 8.15 Counterparts. This Agreement may be executed in two or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile or pdf signature including any electronic signatures complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com shall be considered due execution and shall be binding upon the

32 signatory thereto with the same force and effect as if the signature were an original, not a facsimile or pdf (or other electronic reproduction of a) signature. 8.16 Entire Agreement; Amendments. This Agreement (including all schedules and exhibits hereto) constitute the entire agreement between the parties hereto respecting the subject matter of this Agreement and supersedes all prior agreements, negotiations, understandings, representations and statements respecting the subject matter of this Agreement, whether written or oral. No amendment, modification, alteration, or change in any of the terms of this Agreement shall be valid or binding upon the parties hereto unless made in writing and duly executed by the Company and the Investors of at least a majority in interest of the Shares then held by the Investors, provided that prior to the Closing the consent of all Investors shall be required. Notwithstanding the foregoing, this Agreement may not be amended and the observance of any term of this Agreement may not be waived with respect to any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. The Company, on the one hand, and each Investor, on the other hand, may by an instrument signed in writing by such parties waive the performance, compliance or satisfaction by such Investor or the Company, respectively, with any term or provision of this Agreement or any condition hereto to be performed, complied with or satisfied by such Investor or the Company, respectively. Notwithstanding the foregoing or anything else herein to the contrary, no amendment, modification, alteration, change or waiver of any provision of this Agreement that adversely affects the rights, interests or obligations of the Placement Agent shall be valid without the prior written consent of the Placement Agent, which consent may be granted or withheld in the sole discretion of the Placement Agent. 8.17 Survival. The covenants, representations and warranties made by each party hereto contained in this Agreement shall survive the Closing and the delivery of the Shares. Each Investor shall be responsible only for its own representations, warranties, agreements and covenants hereunder. The last sentences of Section 8.7 and Section 8.11 shall survive any termination of this Agreement. 8.18 Contract Interpretation. This Agreement is the joint product of each Investor and the Company and each provision of this Agreement has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 8.19 Arm’s Length Negotiations. For the avoidance of doubt, the parties acknowledge and confirm that the terms and conditions of the Shares were determined as a result of arm’s-length negotiations. 8.20 Interpretation. The words “hereof,” “herein” and “hereunder” and words of similar import when used in this Agreement will refer to this Agreement as a whole and not to any particular provision of this Agreement, and section and subsection references are to this Agreement unless otherwise specified. The headings in this Agreement are included for convenience of reference only and will not limit or otherwise affect the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they will be deemed to be followed by the words “without limitation.” The phrases “the date of this Agreement,” “the date hereof” and terms of similar import, unless the context otherwise requires, will be deemed to refer to the date set forth in the first paragraph of this Agreement. The meanings given to terms defined herein will be equally applicable to both the singular and plural forms of such terms. All matters to be agreed to by any party hereto must be agreed to in writing by such party unless otherwise indicated herein. References to agreements, policies, standards, guidelines or instruments, or to statutes or regulations, are to such agreements, policies,

33 standards, guidelines or instruments, or statutes or regulations, as amended or supplemented from time to time (or to successors thereto). [Remainder of Page Intentionally Left Blank.]
