Holder is an “accredited investor,” as such term is defined in Regulation D promulgated by the Commission under the 1933 Act, is experienced in investments and business matters, has made investments of a speculative nature and has purchased securities of United States publicly-owned companies in private placements in the past and, with Holder’s representatives, has such knowledge and experience in financial, tax and other business matters as to enable Holder to utilize the information made available by the Company to evaluate the merits and risks of, and to make an informed investment decision with respect to, the proposed purchase, which Holder hereby agrees represents a speculative investment.

(i) Information . Holder and its advisors, if any, have been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Note that have been requested by Holder. Holder and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by Holder or its advisors, if any, or its representatives shall modify, amend or affect Holder’s right to rely on the Company’s representations and warranties contained herein.

Holder has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Note.
