____________________________________________

**<u>The following notes apply generally to the table above:</u>**

(a) With respect to all asset classes, we have attempted to gather the information required by this Form
ABS-15G and Rule 15Ga-1 by, among other things, (i) identifying asset-backed securities transactions that fall within the scope of Rule
15Ga-1 for which we are a securitizer and that are not covered by a filing to be made by an affiliated securitizer ("Covered Transactions"),
(ii) gathering information in our records and the records of our affiliates that acted as securitizers in our transactions regarding demands
for repurchase or replacement of pool assets in Covered Transactions for breaches of representations or warranties concerning those pool
assets ("Repurchases") that is required to be reported on Form ABS-15G ("Reportable Information"), (iii) identifying
the parties in Covered Transactions that have a contractual obligation to enforce any Repurchase obligations of the party or parties making
those representations or warranties based on our records ("Demand Entities"), and (iv) requesting all Reportable Information
from trustees and other Demand Entities that is within their respective possession and which has not been previously provided to us. We
followed up with Demand Entities as we deemed appropriate. The information in this Form ABS-15G has not been verified by any third party.

(b) With respect to the RMBS asset class, assets included in "Assets Subject of Demand" include
only assets where a demand was made during or prior to the reporting period for which we have not yet completed our initial investigation
and assigned such assets to one of the other categories as of the end of the reporting period.

(c) With respect to the RMBS asset class, assets included in "Assets That Were Repurchased or Replaced"
include assets that were previously liquidated and for which a make-whole payment was made in lieu of repurchase. With respect to the
RMBS asset class, assets included in "Assets Pending Repurchase or Replacement" include only assets for which a decision to
repurchase, replace or make-whole has been approved but such action has not been completed, and are shown without regard to cure period
status.

(d) With respect to the RMBS asset class, the principal balances appearing in columns (h), (k), (n), (q),
(t) and (w) and the percentages appearing in columns (i), (l), (o), (r), (u) and (x) reflect the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) for denominator for percentage calculations: aggregate pool principal balance of all assets in the pool as reported to security holders as of the end of the reporting period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) for each calculation related to assets reflected in columns (i), (o), (r), (u) and (x): outstanding principal balance of such asset;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) for each asset relating to column (k) and for each calculation related to assets reflected in column (l): outstanding principal balance of such asset at time of repurchase, replacement or make-whole, plus fees, penalties and accrued interest; and,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) for each asset relating to columns (h), (n), (q), (t) and (w): if known, outstanding principal balance of such asset, plus outstanding fees, penalties and accrued interest; otherwise original principal balance of such asset.

(e) With respect to all asset classes, the scope of this Form ABS-15G is limited to transactions with activity
to report in which Credit Suisse First Boston Mortgage Securities Corp. is the depositor, and the sponsor is either (i) not an affiliate
of Credit Suisse First Boston Mortgage Securities Corp. or (ii) an affiliate of Credit Suisse First Boston Mortgage Securities Corp. that
will not file a Form ABS-15G covering the transaction.

(f) The information in this Form ABS-15G does not include any previously reported repurchase request or demand,
where such repurchase request or demand was subsequently withdrawn and was reflected as having been withdrawn in a prior reporting period,
unless there has been a been a change in reporting status with respect to such repurchase request or demand during the current reporting
period from the status previously reported.

\* Includes loans for which a demand was received, a rebuttal was made and there was no response within 90 days of the rebuttal during the reporting period covered by this Form ABS-15G. The demand related to loans reported in this column may have been received prior to the reporting period covered by this Form ABS-15G.
