            (c) No Consent. The execution, delivery and performance by the
Assignor of this Assignment Agreement and the consummation of the transactions

has been obtained, given, effected or taken prior to the date hereof.

            (d) Authorization; No Breach. The execution and delivery of this
Assignment Agreement have been duly authorized by all necessary partnership
action on the part of the Assignor; neither the execution and delivery by the
Assignor of this Assignment Agreement, nor the consummation by the Assignor of
the transactions herein contemplated, nor compliance by the Assignor with the
provisions hereof, will conflict with or result in a breach of, or constitute a
default under, any of the provisions of the governing documents of the Assignor
or any law, governmental rule or regulation or any material judgment, decree or
order binding on the Assignor or any of its properties, or any of the provisions

pending or, to the knowledge of the Assignor, threatened, before or by any
court, administrative agency, arbitrator or governmental body (A) with respect
to any of the transactions contemplated by this Assignment Agreement or (B) with
respect to any other matter that in the judgment of the Assignor will be

Assignor, materially adversely affect its ability to perform its obligations
under this Assignment Agreement.

            7. Additional Representations and Warranties of the Assignor With
Respect to the Mortgage Loans. The Assignor hereby represents and warrants to
the Assignee as follows:

            (a) Prior Assignments; Pledges. Except for the sale to the Assignee,
the Assignor has not assigned or pledged any Mortgage Note or the related
Mortgage or any interest or participation therein.

            (b) Releases. The Assignor has not satisfied, canceled or
subordinated in whole or in part, or rescinded any Mortgage, and the Assignor
has not released the related Mortgaged Property from the lien of any Mortgage,
in whole or in part, nor has the Assignor executed an instrument that would
effect any such release, cancellation, subordination, or rescission. The
Assignor has not released any Mortgagor, in whole or in part, except in
connection with an assumption agreement or other agreement approved by the
related federal insurer, to the extent such approval was required.

            (c) Compliance with Applicable Laws. With respect to each Mortgage
Loan, any and all requirements of any federal, state or local law including,
without limitation, usury, truth-in-lending, real estate settlement procedures,
consumer credit protection, equal credit opportunity, predatory and abusive
lending or disclosure laws applicable to such Mortgage Loan,


                                       5
<PAGE>

including without limitation, any provisions relating to prepayment charges,
have been complied with.

            (d) High Cost. No Mortgage Loan is categorized as "High Cost"
pursuant to the then-current Standard & Poor's Glossary for File Format for
LEVELS(R) Version 5.7, Appendix E, as revised from time to time and in effect as
of the Original Purchase Date. Furthermore, none of the Mortgage Loans sold by
the Seller are classified as (a) a "high cost mortgage" loan under the Home
Ownership and Equity Protection Act of 1994 or (b) a "high cost home,"
"covered," "high-cost," "high-risk home," or "predatory" loan under any other
applicable state, federal or local law.

            (e) Georgia Fair Lending Act. No Mortgage Loan is secured by a
property in the state of Georgia and originated between October 1, 2002 and
March 7, 2003.

            (f) Credit Reporting. The Assignor will cause to be fully furnished,
in accordance with the Fair Credit Reporting Act and its implementing
regulations, accurate and complete information (i.e., favorable and unfavorable)
on Mortgagor credit files to Equifax, Experian and Trans Union Credit
Information Company (three of the credit repositories), on a monthly basis.

            (g) Arbitration. With respect to any Mortgage Loan originated on or
after August 1, 2004, neither the related Mortgage nor the related Mortgage Note
requires the Mortgagor to submit to arbitration to resolve any dispute arising
out of or relating in any way to any of the transactions contemplated by this
Assignment Agreement.

            (h) Bring Down. To the Assignor's knowledge, with respect to each
Mortgage Loan, no event has occurred from and after the closing date set forth
in such Servicing Agreement to the date hereof that would cause any of the
representations and warranties relating to such Mortgage Loan set forth in
Section 3.2 of the Servicing Agreement to be untrue in any material respect as
of the date hereof as if made on the date hereof. With respect to those
representations and warranties which are made to the best of the Assignor's
knowledge, if it is discovered by the Assignor that the substance of such
representation and warranty is inaccurate, notwithstanding the Assignor's lack
of knowledge with respect to the substance of such representation and warranty,
such inaccuracy shall be deemed a breach of the applicable representation and
warranty.

            It is understood and agreed that the representations and warranties
set forth in Sections 6 and 7 shall survive delivery of the respective mortgage
loan documents to the Assignee or its designee and shall inure to the benefit of
the Assignee and its assigns notwithstanding any restrictive or qualified
endorsement or assignment. Upon the discovery by the Assignor or the Assignee
and its assigns of a breach of the foregoing representations and warranties, the
party discovering such breach shall give prompt written notice to the other
parties to this Assignment Agreement, and in no event later than two (2)
Business Days from the date of such discovery. It is understood and agreed that
the obligations of the Assignor set forth in Section 8 to repurchase or, in
limited circumstances, substitute a Mortgage Loan constitute the sole remedies
available to the Assignee and its assigns on their behalf respecting a breach of
the representations and warranties contained in Sections 6 and 7. It is further
understood and agreed


                                       6
<PAGE>

that, except as specifically set forth in Sections 6 and 7, the Assignor shall
be deemed not to have made the representations and warranties in Section 7(h)
with respect to, and to the extent of, representations and warranties made, as
to the matters covered in Section 7(h), by the Servicer in the Servicing
Agreement (or any officer's certificate delivered pursuant thereto).

            It is understood and agreed that, with respect to the Mortgage
Loans, the Assignor has made no representations or warranties to the Assignee
other than those contained in Sections 6 and 7 and no other affiliate of the
Assignor has made any representations or warranties of any kind to the Assignee.

            8. Representations and Warranties of the Servicer. (a) The Servicer
hereby represents and warrants to the Assignee that, to the extent the Mortgage
Loans will be part of a REMIC, the Servicer shall service the Mortgage Loans and
any real property acquired upon default thereof (including, without limitation,
making or permitting any modification, waiver or amendment of any term of any
Mortgage Loan) in accordance with the Servicing Agreement, but in no event in a
manner that would (a) cause the REMIC to fail to qualify as a REMIC or (b)
result in the imposition of a tax upon the REMIC (including, but not limited to,
the tax on prohibited transactions as defined in Section 860F(a)(2) of the Code,
the tax on contributions to a REMIC set forth in Section 860G(d) of the Code and
the tax on "net income from foreclosure property" as set forth in Section
860G(c) of the Code).

                  (b) Notwithstanding anything to the contrary in the Servicing
Agreement, on or before March 15 of each calendar year, commencing in 2007, the
Servicer shall deliver to the Purchaser, the Master Servicer and the Depositor a
report (in form and substance reasonably satisfactory to the Purchase, the
Master Servicer and the Depositor) regarding the Servicer's assessment of
compliance with the Servicing Criteria during the immediately preceding calendar
year, as required under Rules 13a-18 and 15d-18 of the Exchange Act and Item
1122 of Regulation AB. Such report shall be addressed to the Purchaser, the
Master Servicer and the Depositor and signed by an authorized officer of the
Servicer, and shall address the "Applicable Servicing Criteria" set forth on
Exhibit 3 attached hereto as applicable.

            9. Repurchase of Mortgage Loans. (a) To the extent that SunTrust is
required under the Servicing Agreement or any related agreement (other than this
Assignment Agreement) to which SunTrust and Assignor are parties to repurchase
any Mortgage Loan on account of an Early Payment Default, the Assignee shall be
entitled as a result of the assignments hereunder to enforce such obligation
directly against SunTrust as required by and in accordance with the Servicing
Agreement or such related agreement, as applicable. For purposes of this
Section, "Early Payment Default" shall mean any provision of the Servicing
Agreement or any related agreement to which SunTrust and Assignor are parties
that is designated as an "early payment default" provision or otherwise provides
for the repurchase of any Mortgage Loan in the event of a default in the first
scheduled payment (or any subsequent scheduled payment as specified in such
provision) that is due under such Mortgage Loan after the closing or other date
specified in such agreement. Notwithstanding the foregoing provisions of this
subsection (a), nothing contained herein shall obligate SunTrust to repurchase
any Mortgage Loan unless, and to the extent that, SunTrust is require to
repurchase such Mortgage Loan under the Servicing Agreement or any related
agreement (other than this Assignment Agreement) to which SunTrust and Assignor
are parties.


                                       7
<PAGE>

            (b) Upon discovery or notice of any breach by the Assignor of any
representation, warranty or covenant under this Assignment Agreement that
materially and adversely affects the value of any Mortgage Loan or the interest
of the Assignee therein (it being understood that any such defect or breach
shall be deemed to have materially and adversely affected the value of the
related Mortgage Loan or the interest of the Assignee therein if the Assignee
incurs a loss as a result of such defect or breach), the Assignee promptly shall
request that the Assignor cure such breach and, if the Assignor does not cure
such breach in all material respects within sixty (60) days from the date on
which it is notified of the breach, the Assignee may enforce the Assignor's
obligation hereunder to purchase such Mortgage Loan from the Assignee at the
Repurchase Price as defined in the Servicing Agreement or, in limited
circumstances (as set forth below), substitute a Substitute Mortgage Loan (as
defined below) for such Mortgage Loan. Notwithstanding the foregoing, however,
if such breach is a Qualification Defect as defined in the Servicing Agreement,
such cure or repurchase must ta
