subsection (g):

         "(g) Relationship Between Parties.
         Each party represents to the other party on each date when it enters into a Transaction that:--

(1)        Nonreliance.  (i) It is not relying on any  statement  or  representation  of the other party  regarding
                  the  Transaction  (whether  written or oral),  other than the  representations  expressly made in
                  this  Agreement or the  Confirmation  in respect of that  Transaction  and (ii) it has  consulted
                  with its own legal, regulatory, tax, business,  investment,  financial and accounting advisors to
                  the extent it has deemed  necessary,  and it has made its own  investment,  hedging  and  trading
                  decisions  based upon its own  judgment  and upon any advice from such  advisors as it has deemed
                  necessary and not upon any view expressed by the other party.

(2)        Evaluation and Understanding.

(i)               It has the  capacity to evaluate  (internally  or through  independent  professional  advice) the
                  Transaction  and has  made its own  decision  to enter  into the  Transaction  and in the case of
                  Party B, it has been  directed  by the  Pooling  and  Servicing  Agreement  to  enter  into  this
                  Transaction; and

(ii)              It  understands  the terms,  conditions and risks of the  Transaction  and is willing and able to
                  accept those terms and conditions and to assume those risks, financially and otherwise.

(3)               Purpose.  It is entering  into the  Transaction  for the purposes of managing its  borrowings  or
                  investments,  hedging  its  underlying  assets or  liabilities  or in  connection  with a line of
                  business.

                  (4)      Status of  Parties.  The other  party is not acting as agent,  fiduciary  or advisor for
                  it in respect of the Transaction,

                  (5)      Eligible  Contract  Participant.  It is an "eligible swap  participant"  as such term is
                  defined  in  Section  35.1(b)(2)  of the  regulations  (17 C.F.R 35)  promulgated  under,  and it
                  constitutes an "eligible  contract  participant" as such term is defined in Section 1(a)12 of the
                  Commodity Exchange Act, as amended."

(r)  The ISDA Form Master Agreement is hereby amended as follows

         (i)      The word "third" shall be replaced by the word "second" in the third line of  Section 5(a)(i)  of
the ISDA Form Master Agreement.

         (ii)     TRANSFER,  AMENDMENT AND ASSIGNMENT. No transfer,  amendment,  waiver, supplement,  assignment or
other  modification of this Transaction  shall be permitted by either party (other than a change of Counterparty in
connection  with a change of Trustee in  accordance  with the  Pooling  and  Servicing  Agreement)  unless  each of
Moody's  Investors  Service,  Inc.  ("Moody's")  and Standard and Poor's,  a Division of the McGraw Hill  Companies
("S&P"),  has been provided notice of the same and confirms in writing  (including by facsimile  transmission) that
it will not downgrade,  qualify,  withdraw or otherwise modify its then-current rating of the RASC Series 2006-EMX6
Trust, Home Equity Mortgage Asset-Backed Pass-Through Certificates, Series 2006-EMX6 (the "Certificates").

         (iii)    [RESERVED].

         (iv)     COUNTERPARTY  RATING WITHDRAWAL OR REDUCTION.  In the event that (1) HSBC's short-term  unsecured
and  unsubordinated  debt rating is reduced  below "A-1" by S&P (or if its  short-term  rating is not  available by
S&P, in the event that its  long-term  unsecured and  unsubordinated  debt rating is reduced below "AA-" by S&P) or
(2) either  HSBC's  long-term  unsecured  and  unsubordinated  debt rating is reduced  below "A1" by Moody's or its
short-term  unsecured  and  unsubordinated  debt rating is reduced  below "P1" by Moody's  (or,  if its  short-term
rating is not  available  by Moody's,  its  long-term  unsecured  and  unsubordinated  debt rating is  withdrawn or
reduced  below "Aa3" by Moody's) (and together  with S&P, the "Cap Rating  Agencies",  and such rating  thresholds,
"Approved Rating  Thresholds"),  then within 30 days after such rating withdrawal or downgrade  (unless,  within 30
days after such  withdrawal or downgrade  each Cap Rating Agency has  reconfirmed  its rating for HSBC which was in
effect immediately prior to such withdrawal or downgrade),  HSBC shall, subject to the Rating Agency Condition,  at
its own expense:

                  (a)      assign each  Transaction  to another  counterparty,  which  counterparty  shall have the
Approved Rating Thresholds and shall have been approved by Residential  Funding  Corporation  (which approval shall
not be unreasonably withheld) on terms substantially similar to the terms of this Confirmation;

                  (b)      obtain  guaranty  of, or a  contingent  agreement  of another  person with the  Approved
Rating Thresholds,  to honor HSBC's  obligations under this Confirmation;  provided that such other person has been
approved by Residential Funding Corporation (which approval shall not be unreasonably be withheld);

                  (c)      post  collateral  which  will be  sufficient  to the  applicable  Cap  Rating  Agency to
restore the rating for HSBC which was in effect immediately prior to such withdrawal or downgrade; or

                  (d)      establish any other  arrangement  satisfactory  to HSBC and to the applicable Cap Rating
Agency,  in each case,  sufficient  to restore  the rating for HSBC which was in effect  immediately  prior to such
withdrawal or downgrade.

                  Notwithstanding  the previous  paragraph,  in the event that Party A's  short-term  unsecured and
unsubordinated  debt rating is withdrawn or reduced  below "A-3" by S&P or, if there is no short-term  rating,  its
long-term  unsecured  and  unsubordinated  debt rating is withdrawn or reduced  below "BBB-" by S&P, then within 10
days of such rating  withdrawal  or downgrade  (unless,  within 10 days after such  withdrawal or downgrade S&P has
reconfirmed  the  rating  of the  Certificates  which  was  in  effect  immediately  prior  to such  withdrawal  or
downgrade),  Party A shall, subject to the Rating Agency Condition,  at its own expense, assign this Transaction to
another  counterparty  with the Approved Rating Thresholds and approved by Party B on terms  substantially  similar
to this Confirmation

                  For purposes of this provision,  "Rating Agency  Condition" means, with respect to any particular
proposed  act or omission to act  hereunder  that the party  acting or failing to act must  consult with any of the
Cap Rating  Agencies then providing a rating of the  Certificates  and receive from the Cap Rating Agencies a prior
written  confirmation  that the  proposed  action or inaction  would not cause a  downgrade  or  withdrawal  of the
then-current rating of the Certificates.
