weighted average of the interest rates on the Lower-Tier I REMIC Regular

principal amounts immediately prior to such Distribution Date. On any
Distribution Date, the Certificate Rate on each class of Pool II Subordinated
Certificates will equal the fraction, expressed as a percentage, (I) the
numerator of which will equal the sum of (i) the product of (x) Group 11 Net WAC
and (y) the excess of the aggregate Scheduled Principal Balance of the Group 11
Mortgage Loans over the aggregate outstanding principal balance of the Class
11-A Certificates (prior to giving effect to distributions to be made on such
Distribution Date), (ii) the product of (x) Group 12 Net WAC and (y) the excess
of the aggregate Scheduled Principal Balance of the Group 12 Mortgage Loans over
the aggregate outstanding principal balance of the Class 12-A Certificates
(prior to giving effect to distributions to be made on such Distribution Date)
and (iii) the product of (x) Group 13 Net WAC and (y) the excess of the
aggregate Scheduled Principal Balance of the Group 13 Mortgage Loans over the
aggregate outstanding principal balance of the Class 13-A Certificates (prior to
giving effect to distributions to be made on such Distribution Date) and (II)
the denominator of which will equal the sum of the Group 11 Subordinated Amount,
the Group 12 Subordinated Amount and the Group 13 Subordinated Amount. The
initial Certificate Rate with respect to each class of Pool II Subordinated
Certificates will be approximately 5.813%. For federal income tax purposes, the
Certificate Rate on each Class of Pool II Subordinated Certificates can be
expressed as a per annum rate equal to the weighted average of the interest
rates on the Lower-Tier II REMIC Regular Interests ending with the designation
"A" weighted on the basis of their principal amounts immediately prior to such
Distribution Date. Interest with respect to each Class of Certificates shall be
calculated based on a 360 day year comprised of twelve 30-day months.
