Item 1.       Business

The Registrant is a Delaware Business Trust formed solely for the purpose of
acquiring from First Sierra Receivables IV, Inc., a bankruptcy remote subsidiary
of First Sierra Financial, Inc., certain leases (the "Leases") and interests in
equipment underlying the leases (together the "Receivables") and securitizing
the Receivables through the issuance of Certificates. The Registrant's
operations are restricted so that (a) it does not engage in business with, or
incur liabilities to, any other entity which may bring bankruptcy proceedings
against the Registrant and 9b) the risk is diminished that it will be
consolidated into the bankruptcy proceedings of any other entity. The Registrant
has no other assets except the Receivables and proceeds thereof.
