ITEM 5. Other Events

               On September  23, 1999 (the  "Closing  Date"),  Fremont Home Loan
Trust  1999-3  (the  "Trust")  issued the Home Loan Asset  Backed  Certificates,
Series 1999-3,  Class A-1,  Class A-2 and Class B (the "Offered  Certificates"),
having an aggregate  original  principal  balance of  $500,507,334.  The Offered
Certificates  were issued pursuant to a Pooling and Master Servicing  Agreement,
dated as of September 1, 1999 (the  "Pooling and  Servicing  Agreement"),  among
PaineWebber Mortgage Acceptance Corporation IV, as depositor, Fremont Investment
& Loan, as transferor and master servicer, and The Bank of New York, as trustee.
The Home Loan Asset  Backed  Certificates,  Series  1999-3,  Class X and Class R
(together with the Offered  Certificates,  the "Certificates")  were also issued
pursuant to the Pooling and Servicing Agreement.  The Certificates represent, in
the aggregate, the entire beneficial ownership interest in a separate trust fund
(the "Trust Fund"), the property of which is, as of the Closing Date,  primarily
comprised  of two  pools of  fixed-rate  and  adjustable-rate  home  loans  (the
"Initial Pool 1 Loans" and the "Initial  Pool 2 Loans",  and  collectively,  the
"Initial  Loans") as described herein which are secured by first lien mortgages,
deeds of trust or other similar security instruments.

               Interest on the Offered  Certificates will be distributed on each
Distribution Date (as defined in the Pooling and Servicing  Agreement).  Monthly
payments in reduction of the principal balance of the Offered  Certificates will
be allocated to the Offered  Certificates  in accordance with the priorities set
forth in the Pooling and Servicing Agreement.
