Siena Mortgages 07-5 S.r.l.(Series 1)

Tis will be the seventh RMBS transaction from originator Banca Monte dei Paschi di Siena S.p.A. (see
also under Seashell), with almost a four year gap since the last issuance.

The collateral consists of 57,968 Italian prime residential mortgage loans, all of which were originated
by Banca Monte dei Paschi di Siena. All the loans have been granted to individuals and are guaranteed
by an economic first lien on the actual residential property. All of the debtors pay through direct debit,
with 75.9% of the loans paying on a monthly basis, and the balance paying either on a semi-annual
(22.63%) or quarterly basis (1.47%).

The portfolio is highly granular, with the largest debtor representing only 0.04% of the total pool. Also
on the positive side, the collateral portfolio has a WA current LTV of 58.95% and a WA seasoning of
approximately 2.83 years. However, there is some regional concentration to be seen, with namely
Tuscany and Lazio accounting for 23% and 14.81% of the outstanding pool respectively.
