The Bonds may not be offered or sold in the United States or to, or for the account or benefit of U.S. Persons (as defined in Regulation S under the Securities Act) absent registration or exemption from registration under the U.S. Securities Act of 1933, as amended (the "Securities Act").

The Issuer has not registered and does not intend to register as an investment company under the United States Investment Company Act of 1940, as amended (the "Investment Company Act"), in reliance on the exemption provided in section 3(c)(7) thereof. The Bonds may be offered, sold or delivered (i) outside the United States to persons who are neither "U.S. persons" as defined in Regulation S under the Securities Act ("Regulation S") (each, a "U.S. person") nor "U.S. residents" as determined for the purposes of the Investment Company Act (each, a "U.S. resident") in offshore transactions in reliance on Regulation S (the "Regulation S Bonds") and/or (ii) within the United States in reliance on Rule 144A under the Securities Act ("Rule 144A") only to persons that are both "qualified institutional buyers" (each a "QIB") within the meaning of Rule 144A and "qualified purchasers" within the meaning of section 2(a)(51) of the Investment Company Act and the rules and regulations thereunder (each a "QP") acting for their own account or for the account of another QIB that is a QP (the "Rule 144A Bonds").
