Pursuant to the Letter of Transmittal, each holder of Initial Notes will represent to the Issuers that (i) such holder or other person has full power and authority to tender, sell, assign and transfer the Initial Notes tendered and to acquire Exchange Notes upon the exchange of such tendered Initial Notes and the Issuers will acquire good and marketable title thereto, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim when the same are accepted by the Issuers; (ii) the Exchange Notes acquired pursuant to the Exchange Offer are being acquired in the ordinary course of business of the person receiving such Exchange Notes, whether or not such person is such holder, (iii) neither the holder of the Initial Notes nor any such other person has an arrangement or understanding with any person to participate in a distribution of such Exchange Notes (within the meaning of the Securities Act of 1933, as amended (the “Securities Act”)), and is not participating in, and does not intend to participate in, the distribution of such Exchange Notes, (iv) if the holder is not a broker-dealer, the holder is not engaged in, and does not intend to engage in, a distribution of the Exchange Notes and (v) neither the holder nor any such other person is an “affiliate” (as defined in Rule 405 under the Securities Act) of the Issuers or, if such holder or such other person is an “affiliate,” that such holder or such other person will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable.
