ARTICLE V

REPRESENTATIONS AND WARRANTIES OF NNA

To induce Company to enter into this Agreement and the transactions contemplated hereby, NNA represents and warrants to Company as of the Effective Date as follows:

5.1 Securities Law Matters.

(a) NNA is acquiring the Exchange Shares for its own account, for investment and not with a view to, or for sale in connection with, the distribution thereof within the meaning of the Securities Act (it being understood that except as otherwise provided in this Agreement and the other Transaction Documents to which it is a party, NNA does not agree to hold the Securities for any minimum or other specific term and reserves the right to dispose of the Exchange Shares at any time in accordance with the Securities Act and state securities Laws applicable to such disposition).

(b) NNA is an “accredited investor,” as that term is as defined in Rule 501(a) of Regulation D under the Securities Act. NNA has sufficient knowledge and experience in financial and business matters to be capable of evaluating the merits and risks of its investment in the Exchange Shares and is capable of bearing the economic risks of such investment.

(c) NNA and its advisers have been furnished with all materials relating to the business, finances and operations of Company, its Subsidiaries and materials relating to the offer and sale of the Exchange Shares which have been requested by NNA or its advisers. NNA and its advisers have been afforded the opportunity to ask questions of Company’s management concerning Company and the Exchange Shares.

(d) NNA understands that except as provided in this Agreement or the Registration Rights Agreement, the sale or re-sale of the Exchange Shares has not been and is not being registered under the Securities Act or any applicable state securities Laws, and the Exchange Shares may not be offered, sold or otherwise transferred unless (i) the Exchange Shares are offered, sold or transferred pursuant to an effective registration statement under the Securities Act, or (ii) the Exchange Shares are offered, sold or transferred pursuant to an exemption from registration under the Securities Act and any applicable state securities Laws.

(e) The principal offices of NNA and the offices of NNA in which it made its decision to purchase the Exchange Shares are located in the State of Massachusetts.

5.2 Restricted Securities. NNA understands that the Exchange Shares have not been registered under the Securities Act, by reason of one or more exemptions from the registration provisions of the Securities Act. NNA understands that the Exchange Shares are “restricted securities” under applicable U.S. federal and state securities Laws and that, pursuant to these Laws, NNA must hold the Exchange Shares until such time as they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. NNA 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 Exchange Shares, and on requirements relating to Company which are outside of NNA’s control.

5.3 Legends. NNA understands that the Exchange Shares and any securities issued in respect of or exchange therefor, may be notated with one or all of the following legends:

(a) “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN 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 TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.”

(b) Any legend set forth in, or required by, the other Transaction Documents.

(c) Any legend required by the securities laws of any state to the extent such laws are applicable to the Exchange Shares represented by the certificate, instrument, or book entry so legended.
