 The
following substitute information is provided in accordance with General

  Item 1119 of Regulation AB
(Affiliations and certain
relationships and related transactions)
 
 The
information regarding this item has been filed in a 424(b)(5) filing dated
December 20, 2007.
 Item 1122 of Regulation AB
(Compliance with applicable
servicing criteria)
  The
reports required by Item 1122(a) and (b) of, or relating to, all parties
determined by the registrant to be participating in the servicing function with
respect to the issuing entity are attached to this Form 10-K as Exhibits 33.1.1,
33.1.2, 33.1.3, 34.1.1, 34.1.2 and 34.1.3.
  The
Agency and Trust division of Citibank, N.A. disclosed the following material
noncompliance with criteria applicable to them during the year ended December
31, 2007: 1122(d)(2)(i) – With respect to certain transactions for which the
transaction documents require that funds be deposited into the custodial bank
accounts on the day funds are received by the Agency and Trust division of
Citibank, N.A., funds were not deposited to the custodial bank accounts in
accordance with the terms of the transaction documents.  In a sample
of selected payments on pool assets received by The Agency and Trust division of
Citibank, N.A., this finding was identified once.  In that instance,
the funds received were deposited into the specified custodial account on the
day after the day they were received.  As the one-day delay only
impacted investment income to which the Agency and Trust division of Citibank,
N.A. was entitled as compensation for its services as securities administrator,
management believes that the delay did not affect the amount of any payments to
any security holder or to any transaction party other than the Agency and Trust
division of Citibank, N.A. 1122(d)(3)(ii) – With respect to certain remittances
during the reporting period, amounts due to investors were allocated and
remitted in accordance with distribution priority and other terms set forth in
the transaction agreements, but were not paid timely to investors.
  Item
1123 of Regulation AB (Servicer compliance statement)
 
 The
statement required by Item 1123 is attached to this Form 10-K as Exhibit
35.1.
