   Disclosure  or caused by any  omission  or alleged  omission  to state in such  Financial  Disclosure  a material  fact
   required to be stated therein or necessary to make the statements  therein,  in light of the circumstances  under which
   they were made, not misleading.

   (f)   Depositor  shall be an express  third party  beneficiary  of this  Agreement  as if it were a party hereto to the
   extent of Depositor's rights explicitly specified herein.

   applicable Significance Percentage.

C.  ADDITIONAL TERMINATION EVENTS:

The following Additional Termination Events will apply to UBS AG:

1.       RATINGS  EVENT.  If a Ratings  Event or Subsequent  Ratings Event (as defined  below) has occurred and UBS AG has
not complied with the requirements  set forth in the succeeding  paragraphs , then an Additional  Termination  Event shall
have  occurred  with  respect to UBS AG and UBS AG shall be the sole  Affected  Party with  respect to such an  Additional
Termination Event.

         RATING AGENCY DOWNGRADE:

         If a Ratings  Event  occurs  with  respect to UBS AG,  then UBS AG shall,  at its own  expense,  (i) assign  this
         Transaction  hereunder to a third party within thirty (30) days of such Ratings  Event that meets or exceeds,  or
         as to which any applicable  credit support  provider meets or exceeds,  the Approved Rating Threshold (as defined
         below) on terms  substantially  similar to this  Confirmation  or (ii)  deliver  collateral  in a form and amount
         acceptable to Fitch,  Moody's and S&P (each a "Rating Agency" and  collectively,  the "Rating  Agencies")  within
         thirty  (30) days of such  Ratings  Event and  subject to written  confirmation  from the  Rating  Agencies  that
         delivery of such  collateral in the context of such downgrade will not result in a withdrawal,  qualification  or
         downgrade of the then current ratings  assigned to the  Certificates.  For the avoidance of doubt, a downgrade of
         the rating on Residential Accredit Loans, Inc. Mortgage Asset-Backed Pass-Through  Certificates,  Series 2006-QO7
         (the "Certificates") could occur in the event that UBS AG does not post sufficient collateral.

         For purposes of this Transaction, a "Ratings Event" shall occur with respect to UBS AG if:

(i)      its short-term  unsecured and unsubordinated  debt rating (the "Short Term Rating") is withdrawn or reduced to or
                      below "P-2" by Moody's and its long term  unsecured and  unsubordinated  debt rating (the "Long Term
                      Rating") is  withdrawn  or reduced to or below "A3" by  Moody's;  or if UBS AG no longer has a Short
                      Term Rating, its Long Term Rating is reduced to or below "A2";

(ii)     its Short Term Rating is reduced below "A-1" by S&P or its Long Term Rating is reduced below "A+" by S&P; or

(iii)    its Long Term Rating is withdrawn or reduced below "A" by Fitch.

              The ratings in (i), (ii) and (iii) are referred to as the "Approved  Ratings  Threshold  (unless,  within 30
              days after such withdrawal or downgrade each Rating Agency has  reconfirmed  the rating of the  Certificates
              which were in effect immediately prior to such withdrawal or downgrade).

         Further,  a "Subsequent  Ratings Event" shall occur if: (i) Party A's Short Term Rating is reduced below "A-3" or
         its Long Term Rating is reduced below "BBB-".  In the case of a Subsequent  Ratings Event,  Party A shall, at its
         sole  expense  and within 10  Business  Days assign  this  Transaction  hereunder  to a third party that meets or
         exceeds,  or as to which any applicable  credit support provider meets or exceeds,  the Approved Rating Threshold
         (as defined below) on terms substantially similar to this Confirmation.

For the purposes hereof:

         "Fitch" means Fitch Ratings, Inc.

         "Moody's" means Moody's Investors Service, Inc.

         "S&P" means Standard & Poor's Rating Services, a division of the Mc-Graw Hill Companies, Inc.

2.       DISCLOSURE  EVENT. If upon the occurrence of a Disclosure Event (as defined in paragraph  (xxiii) above),  UBS AG
has not,  within  10  Business  Days  after  such  Disclosure  Event,  complied  with any of the  provisions  set forth in
paragraph  (xxiii) then a  Termination  Event shall have  occurred with respect to UBS AG with UBS AG as the sole Affected
Party with respect to such Termination Event.

D.  TRANSFER, AMENDMENT AND ASSIGNMENT:

No transfer,  amendment,  waiver,  supplement,  assignment or other modification of this Transaction shall be permitted by
either party unless the Rating Agency  Condition shall have been satisfied;  provided,  however,  that except with respect
to a transfer at the direction of UBS AG, nothing in this  provision  shall impose any obligation on UBS AG to give notice
to any rating agency.

For the purposes hereof,  "Rating Agency  Condition" means with respect to any particular  proposed act or omission to act
hereunder,  that the party  acting or failing to act has  consulted  with each of S&P,  Moody's & Fitch then  providing  a
rating of the  Certificates  and received  written  confirmation  that the proposed  action or inaction  would not cause a
downgrading or withdrawl of the then-current rating of the Certificates.

E.  PAYER TAX REPRESENTATIONS

Each party will be deemed to  represent to the other party on the date on which it enters into this  Transaction  that (in

for this Transaction):

(a)  Non-Reliance.  UBS AG is acting for its own account and, with respect to the  Counterparty,  the Trustee is executing
this  Agreement as Trustee on behalf of the Trust pursuant to the Pooling and Servicing  Agreement,  and each has made its
own independent  decisions to enter into this  Transaction and as to whether this Transaction is appropriate or proper for
it based upon its own judgment and upon advice from such  advisers as it has deemed  necessary.  Each party is not relying
on any  communication  (written or oral) of the other party as investment advice or as a recommendation to enter into this
Transaction;  it being  understood  that  information  and  explanations  relating  to the  terms and  conditions  of this
Transaction  shall  not  be  considered  investment  advice  or a  recommendation  to  enter  into  this  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 this Transaction.  Notwithstanding  the foregoing,  the Counterparty has entered into this Transaction
pursuant to the direction received by it under the Pooling and Servicing Agreement.

(b)  Assessment and  Understanding.  Each party is capable of assessing the merits of and  understands  (on its own behalf
or through  independent  professional  advice),  and accepts,  the terms,  conditions and risks of this Transaction.  Each
party is also capable of assuming and assumes, the risks of this Transaction.

(c) Status of the  Parties.  Neither  party is acting as a fiduciary  for or as an adviser to the other in respect of this
Transaction.

(d)      Eligible  Contract  Participant.  Each party  constitutes  an  "eligible  contract  participant"  as such term is
defined in Section 1(a)12 of the Commodity Exchange Act, as amended.

I.  TRUSTEE CAPACITY:

Deutsche Bank Trust  Company  Americas,  not in its  individual  capacity,  but solely as Trustee with respect to the RALI
Series  2006-QO7  Trust (the  "Trust")  under the  Pooling  and  Servicing  Agreement  in the  exercise  of the powers and
authority  conferred  upon and vested in it thereunder and pursuant to  instruction  set forth  therein,  (ii) each of the
representations,  undertakings and agreements  herein made on the part of the Trust is made and intended not as a personal
representation,  undertaking  or agreement  by the  Trustee,  but is made and intended for the purpose of binding only the
Trust,  (iii)  nothing  herein  contained  shall be  construed as imposing any  liability on the Trustee  individually  or
personally,  to perform any covenant  either  express 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,  and (iv)
under no  circumstances  shall the  Trustee  in its  individual  capacity  be  personally  liable  for the  payment of any
indebtedness  or expenses or be personally  liable for the breach or failure of any obligation,  representation,  warranty
or covenant  made or  undertaken  by the Trust under this  Confirmation  or any other  related  documents  (other than the
Trustee's express obligations under the Pooling and Servicing Agreement).
