Partners LP, the Issuer will retain an investment banking firm to identify
candidates for a transaction involving the sale of the Issuer or its assets. A
more complete description of the rights and obligations of the parties is set

paragraphs (a) through (j) of Item 4 of Schedule 13D. However, the Reporting
