aggregate, reasonably be expected to have a material adverse effect on the ability of the Purchaser to perform its obligations hereunder. 

(c) Restricted Securities. The Purchaser understands that the Allocated Shares are being issued in a transaction that was not, and will
not be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the
Purchaser’s representations as expressed herein. The Purchaser understands that the Allocated Shares are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser
must hold the Allocated Shares indefinitely until such Shares are registered with the Commission and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that
the Company has no obligation to register or qualify the Allocated Shares for resale other than as set forth in the Rights Agreement. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be
conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Allocated Shares, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the
Company is under no obligation and may not be able to satisfy. 
 (d) Accredited Investor. The Purchaser is an accredited investor as
defined in Rule 501(a) of Regulation D promulgated under the Securities Act. The Purchaser’s principal executive offices are in the jurisdiction set forth immediately below the Purchaser’s name on the applicable signature page attached
hereto.

 (e) Experience of the Purchaser. The Purchaser, either alone or together with its
representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Allocated Shares, and has so evaluated the merits and
risks of such investment. The Purchaser is able to bear the economic risk of an investment in the Allocated Shares and is able to afford a complete loss of such investment. 

(f) Access to Information. The Purchaser acknowledges that it has received all the information it considers necessary or appropriate for
deciding whether to purchase the Allocated Shares 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 Allocated Shares and the merits and risks of investing in the Allocated Shares; (ii) access to information about the Company and its respective 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. Notwithstanding the foregoing, neither such inquiries nor any other investigation conducted by or on behalf of the Purchaser or its representatives or counsel shall modify, amend or affect the
Purchaser’s right to rely on the truth, accuracy and completeness of the Company’s representations and warranties contained in this Agreement. 

(g) Brokers and Finders. No Person will have, as a result of the transactions contemplated by this Agreement, any valid right, interest
or claim against or upon the Company or the Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Purchaser. 

(h) Reliance on Exemptions. The Purchaser understands that the Allocated Shares being offered and sold to it in reliance on specific
exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and the Purchaser’s compliance with, the representations, warranties,
agreements, acknowledgements and understandings of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire the Allocated Shares. 

(i) Market Stand-Off. The Purchaser acknowledges and agrees that, it is bound by the market stand-off agreement set forth in Section 11 of Exhibit B to the Rights Agreement (the “Market Stand-Off”), and such agreement is in full force and
effect, and following the consummation of the transactions contemplated by this Agreement will remain in full force and effect, including with respect to the Allocated Shares, and agrees, to be bound thereby with respect to the Allocated Shares.

 (j) Legends. The Purchaser understands that the Allocated Shares may bear one or all
of the following legends: 
 (i) “THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION THAT WAS NOT REGISTERED UNDER
THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED
THERETO OR AN OPINION OF COUNSEL IN A FORM REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.”
