                  (h)      GOVERNING  LAW.  The parties to this  Agreement  hereby agree that the law of the State of
                           New York shall govern their rights and duties in whole,  without regard to conflict of law
                           provisions thereof other than New York General Obligations Law Sections 5-1401 and 5-1402.

                  (i)      SEVERABILITY.  If any term, provision,  covenant,  or condition of this Agreement,  or the
                           application  thereof  to any  party  or  circumstance,  shall  be  held to be  invalid  or
                           unenforceable  (in whole or in part) for any  reason,  the  remaining  terms,  provisions,
                           covenants,  and  conditions  hereof  shall  continue  in full  force and effect as if this
                           Agreement had been executed with the invalid or unenforceable portion eliminated,  so long
                           as this  Agreement  as so modified  continues to express,  without  material  change,  the
                           original  intentions  of the parties as to the subject  matter of this  Agreement  and the
                           deletion of such portion of this  Agreement will not  substantially  impair the respective
                           benefits or expectations of the parties.

                           The parties shall endeavor to engage in good faith  negotiations to replace any invalid or
                           unenforceable  term,  provision,  covenant or condition with a valid or enforceable  term,
                           provision,  covenant or condition, the economic effect of which comes as close as possible
                           to that of the invalid or unenforceable term, provision, covenant or condition.

                  (j)      RECORDING  OF  CONVERSATIONS.  Each  party (i)  consents  to the  recording  of  telephone
                           conversations  between the trading,  marketing and other relevant personnel of the parties
                           in connection with this Agreement or any potential Transaction,  (ii) agrees to obtain any
                           necessary  consent of, and give any  necessary  notice of such  recording to, its relevant

                  (o)      "AFFILIATE"  will  have the  meaning  specified  in  Section  14 of the ISDA  Form  Master
                           Agreement,  provided that the Counterparty  shall be deemed not to have any Affiliates for

         6)       ADDITIONAL  REPRESENTATIONS.  Section 3 of the ISDA Form  Master  Agreement  is hereby  amended  by

                  following Sections 3(g), 3(h) and 3(i):

                  "(g)     RELATIONSHIP BETWEEN PARTIES.

                           (1)      NONRELIANCE.  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.

                           (2)      EVALUATION AND UNDERSTANDING.

                                    (i)     It is  acting  for its own  account  and 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 Deutsche  Bank Trust Company  Americas,  it has entered into this
                                            Agreement  pursuant  to  direction  received  by it under the Pooling and
                                            Servicing Agreement;  it is not relying on any communication  (written or
                                            oral) of the other party as investment  advice or as a recommendation  to
                                            enter into such  transaction;  it being  understood that  information and
                                            explanations  related  to the terms and  conditions  of such  transaction
                                            shall not be considered  investment  advice or a recommendation  to enter
                                            into  such  transaction.  No  communication  (written  or oral)  received
                                            from the other party shall be deemed to be an  assurance  or guarantee as
                                            to the expected results of the 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
                                            (and does, in fact assume) those risks, financially and otherwise.

                           (3)      PRINCIPAL.  The other party is not acting as a fiduciary  or an advisor for it in
                                    respect of this Transaction.

                  (h)      EXCLUSION  FROM  COMMODITIES  EXCHANGE ACT. (A) It is an "eligible  contract  participant"
                           within the meaning of Section 1a(12) of the Commodity  Exchange Act, as amended;  (B) this
                           Agreement and each  Transaction is subject to individual  negotiation  by such party;  and
                           (C) neither this  Agreement nor any  Transaction  will be executed or traded on a "trading
                           facility" within the meaning of Section 1a(33) of the Commodity Exchange Act, as amended.

         7)       SET-OFF.  Notwithstanding  any  provision  of  this  Agreement  or any  other  existing  or  future
                  agreement  (but  without  limiting  the  provisions  of  Section  2(c) and  Section 6 of the Master
                  Agreement),  each party  irrevocably  waives any and all rights it may have to set off, net, recoup
                  or otherwise  withhold or suspend or condition payment or performance of any obligation  between it
                  and the other  party  hereunder  against  any  obligation  between it and the other party under any
                  other  agreements.  The last  sentence  of the first  paragraph  of  Section  6(e) of the ISDA Form
                  Master Agreement shall not apply for purposes of this Transaction.

         8)       ADDITIONAL TERMINATION EVENTS.  The following Additional Termination Events will apply:

                  (i)      DOWNGRADE.  BNY fails to comply with the  Downgrade  Provisions  as set forth in Paragraph
                  4(9).  BNY shall be the sole Affected Party.

         9)       RATINGS DOWNGRADE.  For purposes of each Transaction:

                           confirmation from each of the applicable  Rating Agencies,  and shall have provided notice
                           thereof to BNY,  that the  proposed  action or  inaction  would not cause a  downgrade  or
                           withdrawal of their then-current ratings of the Certificates.

                           (B)      "QUALIFYING  RATINGS"  means,  with  respect  to  the  debt  of any  assignee  or
                           guarantor under Paragraph 4(9)(ii) below,

                                    (x)     a short-term  unsecured and  unsubordinated  debt rating of "P-1" (not on
                                    watch for downgrade),  and a long-term  unsecured and unsubordinated debt of "A1"
                                    (not  on  watch  for  downgrade)  (or,  if it has  no  short-term  unsecured  and

                                    (y)     a short-term  unsecured and  unsubordinated  debt rating of "A-1" by S&P,
                                    and

                                    (z)     a short-term unsecured and unsubordinated debt rating of "F-1" by Fitch.

                           (C)      A  "COLLATERALIZATION  EVENT" shall occur with respect to BNY (or any  applicable
                           credit support provider) if:
                                    (x)     its  short-term  unsecured and  unsubordinated  debt rating is reduced to
                                    "P-1" (and is on watch for downgrade) or below,  and its long-term  unsecured and

                                    (or, if it has no short-term  unsecured and unsubordinated  debt rating, its long
                                    term  rating is  reduced to "Aa3"  (and is on watch for  downgrade)  or below) by
                                    Moody's, or

                                    (y)     its  short-term  unsecured  and  unsubordinated  debt  rating is  reduced
                                    below "A-1" by S&P; or

                                    (z)     its  short-term  unsecured  and  unsubordinated  debt  rating is  reduced
                                    below "F-1" by Fitch.

                           (D)      A "RATINGS  EVENT"  shall  occur with  respect to BNY (or any  applicable  credit
                           support provider) if:

                                    (x)     its short-term  unsecured and unsubordinated  debt rating is withdrawn or
                                    reduced  to  "P-2"  or  below  by  Moody's  and  its   long-term   unsecured  and
                                    unsubordinated  debt is  reduced to "A3" or below  (or,  if it has no  short-term
                                    unsecured  and  unsubordinated  debt  rating,  its long term rating is reduced to
                                    "A2" or below) by Moody's, or

                                    (y)     its long-term  unsecured and  unsubordinated  debt rating is withdrawn or
                                    reduced below "BBB-" by S&P, or

                                    (z)     its long-term  unsecured and  unsubordinated  debt rating is withdrawn or
                                    reduced below "BBB-" by Fitch.

                           For purposes of (C) and (D) above,  such events include those occurring in connection with
                           a merger,  consolidation  or other similar  transaction  by BNY or any  applicable  credit
                           support  provider,  but they shall be deemed not to occur if,  within 30 days (or,  in the
                           case of a Ratings Event,  10 Business  Days)  thereafter,  each of the  applicable  Rating
                           Agencies has reconfirmed  the ratings of the  Certificates,  as applicable,  which were in
                           effect  immediately  prior thereto.  For the avoidance of doubt, a downgrade of the rating
                           on the Certificates could occur in the event that BNY does not post sufficient collateral.

                  (ii)     ACTIONS TO BE TAKEN UPON OCCURRENCE OF EVENT.  Subject,  in each case set forth in (A) and
                  (B) below, to satisfaction of the Rating Agency Condition:

                           (A)      COLLATERALIZATION  EVENT.  If a  Collateralization  Event  occurs with respect to
                           BNY (or any  applicable  credit  support  provider),  then BNY shall,  at its own expense,
                           within thirty (30) days of such Collateralization Ratings Event:

                                    (1)     post collateral  under agreements and other  instruments  approved by the
                                    Counterparty,  such  approval  not to be  unreasonably  withheld,  which  will be
                                    sufficient to restore the immediately prior ratings of the Certificates,

                                    (2)     assign  the  Transaction  to a third  party,  the  ratings of the debt of
                                    which (or of the guarantor of which) meet or exceed the  Qualifying  Ratings,  on
                                    terms substantially similar to this Confirmation,  which party is approved by the
                                    Counterparty, such approval not to be unreasonably withheld,

                                    (3)     obtain a guaranty of, or a contingent  agreement of, another person,  the
                                    ratings of the debt of which (or of the  guarantor  of which)  meet or exceed the
                                    Qualifying  Ratings,  to honor BNY's obligations  under this Agreement,  provided
                                    that such other person is approved by the  Counterparty,  such approval not to be
                                    unreasonably withheld, or

                                    (4)     establish  any  other  arrangement  approved  by the  Counterparty,  such
                                    approval not to be  unreasonably  withheld,  which will be  sufficient to restore
                                    the immediately prior ratings of their Certificates.

                           (B)      RATINGS  EVENT.  If a Ratings Event occurs with respect to BNY (or any applicable
                           credit support  provider),  then BNY shall,  at its own expense,  within ten (10) Business
                           Days of such Ratings Event:

                                    (1)     assign  the  Transaction  to a third  party,  the  ratings of the debt of
                                    which (or of the guarantor of which) meet or exceed the  Qualifying  Ratings,  on
                                    terms substantially similar to this Confirmation,  which party is approved by the
                                    Counterparty, such approval not to be unreasonably withheld,

                                    (2)     obtain a guaranty of, or a contingent  agreement of, another person,  the
                                    ratings of the debt of which (or of the  guarantor  of which)  meet or exceed the
                                    Qualifying  Ratings,  to honor BNY's obligations  under this Agreement,  provided
                                    that such other person is approved by the  Counterparty,  such approval not to be
                                    unreasonably withheld, or

                                    (3)     establish  any  other  arrangement  approved  by the  Counterparty,  such
                                    approval not to be  unreasonably  withheld,  which will be  sufficient to restore
                                    the immediately prior ratings of the Certificates.

10)      COMPLIANCE  WITH  REGULATION AB. It shall be a disclosure  event  ("DISCLOSURE  EVENT") if, on any Business
                  Day after the date hereof,  Sponsor requests from BNY the financial  information  described in Item
                  1115(b)  of  Regulation  AB under  the  Securities  Act of 1933,  as  amended,  and the  Securities
                  Exchange Act of 1934,  as amended (the  "EXCHANGE  ACT")  ("REGULATION  AB"),  (such  request to be
                  based on the  reasonable  determination  by  Sponsor,  in good  faith,  that  such  information  is
                  required  under  Regulation  AB) (the "REG AB FINANCIAL  DISCLOSURE").  Within 10 Business  Days of
                  the  occurrence of a Reg AB  Disclosure  Event,  BNY, at its own expense,  shall (a) provide to the
                  Sponsor the Reg AB Financial  Disclosure,  or (b) secure  another entity to replace BNY as party to
                  this Agreement on terms  substantially  similar to this Agreement and subject to prior notification
                  to the applicable  Rating Agencies,  the debt rating of which entity (or guarantor  therefor) meets
                  or exceeds the  qualified  ratings  (or which  satisfies  the Rating  Agency  Condition)  and which
                  entity  is able to  comply  with  the  requirement  of Item  1115(b)  of Reg AB.  If  permitted  by
                  Regulation  AB, any  required  Reg AB  Financial  Disclosure  may be provided by  incorporation  by
                  reference from reports filed pursuant to the Exchange Act.

         11)      ADDITIONAL  PROVISIONS.  Notwithstanding  the terms of  Sections  5 and 6 of the ISDA  Form  Master
                  Agreement,  if  Counterparty  has satisfied its payment  obligations  under Section  2(a)(i) of the
                  ISDA  Form  Master  Agreement,  and  shall,  at the  time,  have  no  future  payment  or  delivery
                  obligation,  whether  absolute or contingent,  then unless BNY is required  pursuant to appropriate
                  proceedings  to  return to  Counterparty  or  otherwise  returns  to  Counterparty  upon  demand of
                  Counterparty any portion of such payment,  (a) the occurrence of an event described in Section 5(a)
                  of the ISDA Form Master  Agreement  with respect to  Counterparty  shall not constitute an Event of
                  Default or Potential  Event of Default with respect to  Counterparty  as the  Defaulting  Party and
                  (b) BNY shall be entitled  to  designate  an Early  Termination  Date  pursuant to Section 6 of the
                  ISDA Form Master  Agreement  only as a result of a  Termination  Event set forth in either  Section
                  5(b)(i) or Section  5(b)(ii) of the ISDA Form Master  Agreement with respect to BNY as the Affected
                  Party or Section  5(b)(iii) of the ISDA Form Master  Agreement  with respect to BNY as the Burdened
                  Party.  For  purposes of the  Transaction  to which this  Agreement  relates,  Counterparty's  only
                  obligation  under Section  2(a)(i) of the ISDA Form Master  Agreement is to pay the Fixed Amount on
                  the Fixed Rate Payer Payment Date.

         12)      PAYMENTS.  BNY will, unless otherwise  directed by the Trustee,  make all payments hereunder to the
                  Trustee.  Payment  made to the  Trustee  at the  account  specified  herein or to  another  account
                  specified in writing by the Trustee shall satisfy the payment  obligations  of BNY hereunder to the
                  extent of such payment.

         13)      LIMITATION  OF  TRUSTEE  LIABILITY.   Notwithstanding  anything  herein  to  the  contrary,  it  is
                  expressly  understood and agreed by the parties  hereto that (a) this letter  agreement is executed
                  and delivered by Deutsche Bank Trust Company  Americas  ("DBTCA"),  not individually or personally,

                  authority  conferred  and  vested  in  it,  (b)  each  of  the  representations,  undertakings  and
                  agreements  herein made on the part of the RALI Series  2006-QS9  Trust is made and intended not as
                  personal  representations,  undertakings  and  agreements by DBTCA but is made and intended for the
                  purpose of binding  only the RALI Series 2006- QS9 Trust,  (c) nothing  herein  contained  shall be
                  construed as creating any liability on DBTCA  individually  or personally,  to perform any covenant
                  either expressed or implied  contained herein,  all such liability,  if any, being expressly waived
                  by the  parties  hereto  and by any  Person  claiming  by,  through  or under the  parties  hereto;
                  provided  that  nothing  in this  paragraph  shall  relieve  DBTCA from  performing  its duties and
                  obligations  under the Pooling and Servicing  Agreement in accordance with the standard of care set
                  forth therein,  and (d) under no circumstances  shall DBTCA be personally liable for the payment of
                  any  indebtedness  or expenses  of the RALI  Series  2006- QS9 Trust or be liable for the breach or
                  failure of any  obligation,  representation,  warranty or covenant  made or  undertaken by the RALI
