         Capitalized terms used but not defined herein have the meanings
assigned to them in the Prospectus Supplement dated June 24, 1999 (the
"Prospectus Supplement").

         The Depositor is in the process of soliciting the consent of holders
of the Class B Certificates to amendment of the Pooling and Servicing
Agreement. If the amendment is approved by each Class B Certificateholder, the
definition of "Targeted Overcollateralization Amount" on page S-31 of the
Prospectus Supplement will be deleted and replaced with the following:

          The "Targeted Overcollateralization Amount" for any Distribution
Date will be

               (a)  before the Stepdown Date, the greater of

                    (1)  the product of 4.30% and the Cut-off Date Balance,
                         and

                    (2)  (A) 125% of the product of (x) the Three Month
                         Delinquency Rate and (y) the Total Loan Balance minus
                         (B) the Class Principal Amount of the Class B
                         Certificates before giving effect to distributions of
                         principal thereon on the related Distribution Date or
                         application of any Applied Loss Amount on that
                         Distribution Date; and

               (b)  on and after the Stepdown Date, the greatest of

                    (1)  the product of 8.60% and the Total Loan Balance for
                         the related Distribution Date,

                    (2)  the amount calculated in accordance with clause
                         (a)(2) above,

                    (3)  the product of 0.75% and the Cut-Off Date Balance,

                    (4)  the sum of the three largest outstanding principal
                         balances of the Mortgage Loans, and

                    (5)  the total outstanding principal balance of all
                         Mortgage Loans 270 or more days delinquent, all
                         Mortgage Loans in foreclosure and all REO Properties
                         as of the last day of the related Due Period.

          The Underwriter, as holder of $9,216,554 in initial Certificate
Principal Amount of Class B Certificates, has consented to the amendment. Any
purchaser of Class B Certificates from the Underwriter will be bound by that
consent and will not be entitled to withdraw it. The holder of the Class R
Certificate and MBIA have advised the Depositor that each of them will consent
to the proposed amendment. MBIA is entitled to exercise all consent rights of
the Senior Certificates under the Pooling and Servicing Agreement

          If the proposed amendment is approved, the Targeted
Overcollateralization Amount as calculated pursuant to clause (a)(2) will be
less likely to exceed the amount calculated pursuant to clause (a)(1) than
would be the case if the proposed amendment is not adopted. Therefore, under
certain circumstances the Targeted Overcollateralization Amount will be lower,
prior to the Stepdown Date, if the proposed amendment is approved than would
be the case if the proposed amendment is not adopted.

          Prospective investors in Class B Certificates should make their
investment decision on the basis of an expectation that the amendment will be
adopted.

          This Supplement corrects and supersedes the Supplement dated January
25, 2000.
