               CONVEYANCE OF THE UNDERLYING CERTIFICATES; ORIGINAL ISSUANCE OF CERTIFICATES

Section 2.01.      Conveyance of the Underlying Certificates.

(a)      The Depositor,  concurrently with the execution and delivery hereof, does hereby sell,  transfer,
assign,  set-over  and  otherwise  convey  to the  Trustee,  in  trust,  for the use  and  benefit  of the
Certificateholders  and the Certificate  Insurer,  without recourse,  all the right, title and interest of
the Depositor in and to (i) the Underlying  Certificates,  including all amounts payable on the Underlying
Certificates  in accordance  with the terms thereof on or after the Closing Date,  (ii) the Sale Agreement
and (iii) all its right,  title and  interest,  if any, in all other assets  constituting  the Trust Fund.
The Group V, Group VI, Group VII, Group VIII and Group IX  Certificates  will also have the benefit of the
Policy.

(b)      In  connection  with such  transfer and  assignment,  and  concurrently  with its  execution  and
delivery of this Agreement,  the Depositor shall have caused the Underlying  Certificates to be registered
in  the  name  of  the  Securities  Administrator  on  behalf  of  the  Trustee  for  the  benefit  of the
Certificateholders.

(c)      It is intended that the conveyances by the Depositor to the Securities  Administrator,  on behalf
of the  Trustee,  of the  Underlying  Certificates  as provided for in this Section 2.01 be construed as a
sale by the  Depositor  to the  Securities  Administrator,  on behalf of the  Trustee,  of the  Underlying
Certificates.  Further,  it is not  intended  that  any  such  conveyance  be  deemed  to be a grant  of a
security  interest in the Underlying  Certificates  by the Depositor to the Securities  Administrator,  on
behalf of the  Trustee,  to secure a debt or other  obligation  of the  Depositor.  However,  in the event
that the  Underlying  Certificates  are held to be  property of the  Depositor,  or if for any reason this
Agreement is held or deemed to create a security  interest in the Underlying  Certificates,  then (a) this
Agreement shall  constitute a security  agreement  within the meaning of Article 9 of the New York Uniform
Commercial  Code;  (b) the  conveyance  provided  for in Section 2.01 shall be deemed to be a grant by the
Depositor to the Securities  Administrator,  on behalf of the Trustee, of, and the Depositor hereby grants
to the Securities  Administrator,  on behalf of the Trustee, as security for its obligations  hereunder, a
security  interest in all of the  Depositor’s  right,  title and interest,  whether now owned or hereafter
acquired, in and to (1) the Underlying  Certificates,  all amounts payable on the Underlying  Certificates
in accordance  with the terms thereof on or after the Closing Date,  (3) the Sale  Agreement,  (4) all its
right, title and interest,  if any, in all other assets  constituting the Trust Fund, and (5) all proceeds
of the  foregoing.  It is also intended that the Trust be classified  for federal income tax purposes as a
grantor  trust  under  Subpart  E,  part  I of  subchapter  J of  chapter  1 of the  Code,  of  which  the
Certificateholders  are owners,  rather than a partnership,  an association  taxable as a corporation or a
taxable  mortgage  pool.  The  powers  granted  and  obligations  undertaken  in this  Agreement  shall be
construed so as to further such intent.

                  The  Depositor  and the  Securities  Administrator,  on  behalf of the  Trustee,  at the
Depositor’s or the Majority  Certificateholders’  direction,  shall,  to the extent  consistent  with this
Agreement,  take such actions as may be necessary to ensure that, if this  Agreement were deemed to create
a security interest in the Underlying  Certificates and the other property  described above, such security
interest  would be a  perfected  security  interest of first  priority  under  applicable  law and will be
maintained as such throughout the term of this Agreement.

Section 2.02......Acceptance of Trust Fund by the  Securities  Administrator,  on behalf of the Trustee;
Initial Issuance of Certificates.

                  The  Securities  Administrator,  on behalf of the Trustee,  acknowledges  receipt of the
Underlying  Agreements  and the receipt by it and the transfer,  delivery and assignment to the Securities
Administrator,  on behalf of the  Trustee,  of the  Underlying  Certificates,  in good  faith and  without
notice of any adverse claim,  and the assignment to the Securities  Administrator on behalf of the Trustee
of all other  assets  included in the Trust Fund and declares  that it holds and will hold the  Underlying
Certificates  and all other assets  included in the Trust Fund in trust for the  exclusive use and benefit
of  all  present  and  future   Certificateholders  in  accordance  with  the  terms  of  this  Agreement.
Concurrently  with such  transfer,  delivery  and  assignment  and in exchange  therefor,  pursuant to the
written  request of the Depositor  executed by an officer of the Depositor,  the Securities  Administrator
has executed and caused to be  authenticated  and  delivered  to or upon the order of the  Depositor,  the
Certificates in authorized denominations evidencing the entire beneficial ownership of the Trust.

                  Until the Trust is  terminated  in  accordance  with  Section  7.01,  except as provided
herein,  the  Securities  Administrator  on behalf of the Trustee  shall not assign,  sell,  dispose of or
transfer any interest in the Underlying  Certificates  or any other asset  constituting  the Trust Fund or
permit the Underlying  Certificates or any other asset  constituting the Trust Fund to be subjected to any
lien,  claim or encumbrance  arising by,  through or under the Trustee or any person  claiming by, through
or under the Trustee.

Section 2.03.      Representations and Warranties of the Depositor and the Trustee.

(a)      The Depositor hereby  represents and warrants to the Trustee,  the Certificate  Insurer,  and the
Securities Administrator and for the benefit of the Certificateholders, as of the Closing Date, that:

(i)      The Depositor is a corporation  duly organized,  validly  existing and in good standing under the
         laws of the State of Delaware,  and the  Depositor  is  possessed  of all  licenses  necessary to
         carry on its business.

(ii)     The  execution  and  delivery  of  this  Agreement  by the  Depositor,  and the  performance  and
         compliance  with the terms of this Agreement by the Depositor,  will not violate the  Depositor’s
         certificate of  incorporation  or bylaws or constitute a default (or an event which,  with notice
         or lapse of time, or both,  would  constitute a default)  under,  or result in the breach of, any
         material  agreement or other  instrument  to which it is a party or which is  applicable to it or
         any of its assets.

(iii)    The  Depositor  has the full  right,  power  and  authority  to enter  into  and  consummate  all

         performance of this Agreement, and has duly executed and delivered this Agreement.

(iv)     This Agreement,  assuming due authorization,  execution and delivery by the Trustee,  constitutes
         a valid,  legal and binding  obligation of the  Depositor,  enforceable  against the Depositor in
         accordance   with  the  terms  hereof,   subject  to  (A)  applicable   bankruptcy,   insolvency,
         reorganization,  moratorium  and other  laws  affecting  the  enforcement  of  creditors’  rights
         generally,  and (B) general  principles  of equity,  regardless  of whether such  enforcement  is
         considered in a proceeding in equity or at law.

(v)      The Depositor is not in violation  of, and its  execution and delivery of this  Agreement and its
         performance  and compliance  with the terms of this Agreement will not constitute a violation of,
         any law, any order or decree of any court or arbiter,  or any order,  regulation or demand of any
         federal,  state or local  governmental  or  regulatory  authority,  which  violation is likely to
         affect  materially and adversely  either the ability of the Depositor to perform its  obligations
         under this Agreement or the financial condition of the Depositor.

(vi)     No litigation is pending or, to the best of the Depositor’s  knowledge,  threatened,  against the
         Depositor  which,  if determined  adversely to the  Depositor,  would prohibit the Depositor from
         entering into this Agreement or is likely to materially  and adversely  affect either the ability
         of the Depositor to perform its  obligations  under this Agreement or the financial  condition of
         the Depositor.

(vii)    The  Depositor  was,  immediately  prior to the transfer of the  Underlying  Certificates  to the
         Securities  Administrator  on behalf of the Trust,  the sole owner  thereof free and clear of any

         claim, lien, charge,  encumbrance or security interest  (including  without  limitation,  federal
         tax liens or liens arising under ERISA).

(ix)     The Depositor has not assigned any interest in the Underlying  Certificates or any  distributions
         thereon, except as contemplated herein.

(x)      The Securities  Administrator,  on behalf of the Trustee, will be entitled to distributions under
         the  Underlying  Agreements  equal to all  distributions  of interest and  principal  made on the
         Underlying Certificates.

(xi)     The  information  relating  to the  Underlying  Certificates  set forth in Schedule A is true and
         correct in all material respects.

(xii)    The transfer of the Underlying  Certificates by the Depositor to the Securities  Administrator on
         behalf of the Trust pursuant to this  Agreement is an absolute sale. The Underlying  Certificates
         have been  reregistered  in the name of the  Securities  Administrator  on behalf of the  Trustee
         through the facilities of the Depositary.

(xiii)   The  Underlying  Certificates  are  “regular  interests”  in a real  estate  mortgage  investment
         conduit within the meaning of Section 860G(a)(1) of the Code.

(xiv)    The Depositor has no actual knowledge after reasonable  inquiry that the Underlying  Certificates
         (1) were not validly issued by the related  Underlying  Trust, (2) are not  outstanding,  (3) are
         not the legal,  valid,  binding and enforceable  obligation of the related  Underlying Trust, and
         (4) are not  entitled  to the  benefits  of the  Underlying  Agreements  pursuant  to which  such
         Underlying  Certificates  were  issued  (except  as limited by  bankruptcy,  insolvency  or other
         similar laws  affecting  the  enforcement  of creditors’  rights  generally or to the extent that
         such  enforceability  may be subject to the exercise of judicial  discretion in  accordance  with
         general equitable principles).

(b)      The Trustee  hereby  represents and warrants to the Depositor,  the  Certificate  Insurer and for
the benefit of the Certificateholders, as of the Closing Date, that:

(i)      The Trustee is a national  banking  association,  duly  organized and validly  existing under the
         laws of the United States of America.

(ii)     The execution and delivery of this Agreement by the Trustee,  and the  performance and compliance
         with the terms of this  Agreement  by the  Trustee,  will not  violate the  Trustee’s  charter or
         bylaws or constitute a default (or an event which,  with notice or lapse of time, or both,  would
         constitute  a  default)  under,  or result in the  breach of,  any  material  agreement  or other
         instrument to which it is a party or which is applicable to it or any of its assets.

(iii)    The  Trustee  has the full power and  authority  to enter into and  consummate  all  transactions
         contemplated  by this Agreement,  has duly authorized the execution,  delivery and performance of

         Securities  Administrator,  constitutes  a valid,  legal and binding  obligation  of the Trustee,
         enforceable  against the Trustee in accordance  with the terms hereof,  subject to (A) applicable
         bankruptcy,  insolvency,  reorganization,  moratorium and other laws affecting the enforcement of
         creditors’ rights  generally,  and (B) general  principles of equity,  regardless of whether such
         enforcement is considered in a proceeding in equity or at law.

(v)      The Trustee is not in violation  of, and its  execution  and delivery of this  Agreement  and its
         performance  and compliance  with the terms of this Agreement will not constitute a violation of,
         any law, any order or decree of any court or arbiter,  or any order,  regulation or demand of any
         federal,  state or local  governmental  or  regulatory  authority,  which  violation is likely to
         affect  materially  and  adversely  either the ability of the Trustee to perform its  obligations
         under this Agreement or the financial condition of the Trustee.

(vi)     No  litigation  is pending or, to the best of the Trustee’s  knowledge,  threatened,  against the
         Trustee  which would  prohibit  the Trustee  from  entering  into this  Agreement or is likely to
         materially  and  adversely  affect  either the ability of the Trustee to perform its  obligations
         under this Agreement or the financial condition of the Trustee.

(vii)    The  Underlying   Certificates  will  be  held  by  the  Securities   Administrator  through  the
         Depository,  the  information  relating to the  Underlying  Certificates  set forth on Schedule A
         hereto conforms to information  set forth in the Prospectus  dated March 28, 2006, the Prospectus
         Supplement  dated  June 29,  2006  and the  Prospectus  Supplement  dated  July 28,  2006 for the
         Underlying  Certificates (as applicable);  it has acquired the Underlying  Certificates  from the
         Depositor  in  good  faith,  for  value,  and,  to the  best  of the  Securities  Administrator’s
         knowledge,  without notice or actual knowledge of any adverse claim,  lien,  charge,  encumbrance
         or security interest  (including,  without  limitation,  federal tax liens or liens arising under
         ERISA);  it has not and will not, in any capacity except as Securities  Administrator,  on behalf
         of the  Certificateholders,  assert any claim or interest in the Underlying Certificates and will
         hold such  Underlying  Certificates  and the proceeds  thereof in trust  pursuant to the terms of
         this  Agreement;  and it has not  encumbered or transferred  its right,  title or interest in the
         Underlying Certificates.

(c)      It is understood and agreed that the foregoing  representations  and warranties shall survive the
execution  and delivery of this  Agreement.  Upon  discovery by any party hereto of a breach of any of the
foregoing  representations  and warranties  which  materially  and adversely  affects the interests of the
Certificateholders,  the Certificate  Insurer or any party hereto,  the party discovering such breach will
give  prompt  written  notice  thereof  to the  other  parties  hereto,  the  Certificateholders  and  the
Certificate  Insurer.  Within  thirty  (30) days of the  earlier of either  discovery  by or notice to the
Depositor of any breach of a  representation  or warranty of the Depositor  that  materially and adversely
affects the  interests of the  Certificateholders,  the Depositor  shall use its best efforts  promptly to
cure such breach in all material  respects and, if such breach cannot be cured,  the Depositor  shall,  at
the  election  of  the  Majority  Certificateholders,   repurchase  the  Underlying  Certificates  at  the
Repurchase  Price.  If  the  Depositor  is to  repurchase  the  Underlying  Certificates,  the  Securities
Administrator  shall promptly  determine the Repurchase  Price in accordance with the definition  thereof.
Repurchase of the Underlying  Certificates  pursuant to the foregoing  provisions of this Section  2.03(c)
shall be  accomplished  by deposit by the Depositor in the  Certificate  Account on the Business Day prior
to the next succeeding  Distribution  Date of the amount of the Repurchase  Price. No such purchase by the
Depositor under this Section 2.03(c) will be permitted  without the consent of the Certificate  Insurer if
such  repurchase  would  cause a draw on the Policy to be made or if any  amounts  due to the  Certificate
Insurer would remain unreimbursed on the final Distribution Date.

Section 2.04......Grantor  Trust.  The trust  created  hereby is  intended  to qualify  as an  “investment
trust”  within the meaning of Treasury  Regulation  §301.7701-4(c),  and it is neither the purpose nor the
intent  of the  parties  hereto  to  create  a  partnership,  joint  venture,  taxable  mortgage  pool  or
association  taxable  as a  corporation  between  or among  the  Certificateholders,  the  Trustee  or the
Depositor.  In  furtherance  of the  foregoing,  the purpose of the Trust shall be to protect and conserve
the assets of the Trust,  and the Trust  shall not at any time  engage in or carry on any kind of business
or any kind of commercial or investment activity.  Subject to the foregoing, the Trust shall:

(i)      issue the  Certificates  to, or at the written  direction  of, the  Depositor in exchange for the
         Underlying Certificates;

(ii)     perform the activities of the Trust that are expressly set forth in this Agreement;

(iii)    engage in those  activities that are reasonably  necessary,  suitable or convenient to accomplish
         the foregoing or are incidental thereto or connected therewith; and

(iv)     subject to compliance  with this  Agreement,  engage in such other  activities as may be required
         in connection  with  conservation of the assets of the Trust and the making of  distributions  to
         the Certificateholders.

                  The Trust is hereby  authorized to engage in the foregoing  activities.  The Trust shall
not engage in any activity  other than the  foregoing or other than as required or authorized by the terms
of  this  Agreement   while  any   Certificate   is  outstanding   without  the  consent  of  all  of  the
Certificateholders;  provided,  however,  that in no event shall the Trustee or any other  Person have any
power  to  vary  the  investment  of the  Certificateholders  in the  Certificates  or to  substitute  new
investments  or reinvest so as to enable the Trust to
take  advantage of variations in the market to improve the  investment  of the  Certificateholders  in the
Certificates.

                                PAYMENTS AND REPORTS TO CERTIFICATEHOLDERS

Section 3.01.     Administration of the Trust Fund and the Underlying Certificates.

                  If  at  any  time  the  Securities   Administrator,   as  a  holder  of  the  Underlying
Certificates, is requested in such capacity, whether by a Certificateholder,  a holder of a certificate of
the  Underlying  Series or a party to the related  Underlying  Agreement or any other Person,  to take any
action or to give any consent,  approval or waiver,  including,  without limitation, in connection with an
amendment of the related Underlying Agreement,  the Securities  Administrator shall promptly notify all of
the Holders of the related  Certificates,  the  Certificate  Insurer and the Depositor of such request and
of its planned  course of action with  respect  thereto and the  Securities  Administrator  shall,  in its
capacity as a holder of such  Underlying  Certificates,  take such action in connection  with the exercise
and/or  enforcement  of any rights and/or  remedies  available to it in such capacity with respect to such
request, as the majority of Certificateholders of the related Certificate Group shall direct in writing.

Section 3.02.    Collection of Monies.

(a)      In  connection  with its  receipt  of any  distribution  on the  Underlying  Certificates  on any
Underlying  Certificates  Distribution  Date,  the  Securities  Administrator  shall  review  the  related
Underlying  Distribution  Date Statement and shall confirm that the aggregate amount of such  distribution
received by it with  respect to each related  class of  Underlying  Certificates  is  consistent  with the
Underlying  Distribution  Date Statement (it being understood that the Securities  Administrator  shall be
entitled to rely on the accuracy and correctness of the Underlying Distribution Date Statement).

(b)      If the Securities  Administrator  receives a Notice of Final Distribution in respect of any class
of Underlying  Certificates,  the Securities  Administrator  shall present and surrender  such  Underlying
Certificate which is in certificated form for final payment thereon,  if required,  in accordance with the
terms and conditions of the related  Underlying  Agreement and such notice.  The Securities  Administrator
shall promptly deposit in the Certificate  Account the final  distribution  received upon presentation and
surrender of such Underlying  Certificate  for  distribution in accordance with Section 3.05 hereof on the
next succeeding Distribution Date for the related Certificates.

Section 3.03.     Establishment of Certificate Account; Deposits Therein.

(a)      The  Securities  Administrator,  for the benefit of the  Certificateholders  and the  Certificate
Insurer,  shall  establish and maintain one or more interest  bearing trust  accounts  (collectively,  the
“Certificate Account”),  each of which shall be an Eligible Account,  entitled “Wells Fargo Bank, N.A., as
securities  administrator  for the  registered  holders of Bear  Stearns  ALT-A  Trust  2006-R1,  Mortgage
Pass-Through  Certificates,  Series  2006-R1,”  held in  trust  by the  Securities  Administrator  for the
benefit of the  Certificateholders  and the Certificate Insurer. The Securities  Administrator shall cause
to be  deposited  directly  into the  Certificate  Account all  distributions  received by the  Securities
Administrator  on the  Underlying  Certificates  and the Policy,  from  whatever  source,  and all amounts
received by it representing  payment of a Repurchase Price pursuant to Section 2.03(c),  subsequent to the
Closing  Date.  The  Certificate  Account  is  initially  located  at the  Securities  Administrator.  The
Securities  Administrator shall give notice to the Depositor,  the Trustee, the Certificate Insurer and to
Certificateholders  of any new  location  of the  Certificate  Account  prior to any change  thereof.  The
Securities  Administrator  shall  have the right to create  sub-accounts  of the  Certificate  Account  to
facilitate the administration of funds.

(b)      In the event  that  payments  in respect  of the  Underlying  Certificates  are  received  by the
Securities  Administrator prior to the related Distribution Date, the Securities  Administrator may invest
such funds deposited in the Certificate  Account in one or more Permitted  Investments held in the name of
the Securities  Administrator and shall receive as compensation,  any interest or investment income earned
on  such  Permitted  Investments,  which  may  be  withdrawn  by  the  Securities  Administrator  on  each
Distribution  Date and shall not  constitute  Available  Funds.  Notwithstanding  the  foregoing,  no such
Permitted  Investment may mature later than such related  Distribution  Date and no such investment  shall
be sold prior to its maturity date. The amount of any losses  incurred in respect of any such  investments
shall be  deposited  in the  Certificate  Account  by the  Securities  Administrator  out of its own funds
immediately as realized.

(c)      The  Depositor  shall cause all  distributions  received on the  Underlying  Certificates  by the
Depositor or any of its Affiliates  after the Closing Date to be provided to the Securities  Administrator
for deposit into the Certificate Account.

Section 3.04.     Permitted Withdrawals From the Certificate Account.

                  The Securities  Administrator  may from time to time withdraw funds from the Certificate
Account for the following purposes:

(i)      to make distributions in the amounts and in the manner provided for in Section 3.05;

(ii)     to pay to the Person entitled thereto any amount deposited in the Certificate Account in error;

(iii)    to clear and terminate the Certificate Account upon the termination of this Agreement;

(iv)     to pay itself, as additional  compensation,  the net reinvestment  income permitted to be paid to
         it as provided in Section 3.03(b); and

(v)      to pay the Certificate Insurer its Aggregate Premium Amount.

On each  Distribution  Date, the Securities  Administrator  shall withdraw all funds from the  Certificate
Account and shall use such funds  withdrawn from the Certificate  Account only for the purposes  described
in this Section 3.04 and in Section 3.05.  Notwithstanding  the  priorities  set forth in Section  3.05(a)
with respect to the Insured  Certificates,  on each Distribution  Date, the Securities  Administrator will
distribute  the  Aggregate   Premium  Amounts   payable  to  the  Certificate   Insurer  out  of  interest
distributions  received on the related Underlying  Certificates on such Distribution Date, prior to making
any distributions of interest to the Certificates.

or the accrual of discount that the Securities  Administrator  reasonably  believes are  applicable  under
the Code.  The consent of  Certificateholders  shall not be required  for such  withholding.  In the event
the Securities  Administrator does withhold any amount from payments to any Certificateholder  pursuant to
federal  withholding  requirements,  the Securities  Administrator  shall indicate the amount  withheld to
such Certificateholders.

than the  Interest  Only  Certificates)  until the Current  Principal  Amount  thereof has been reduced to
zero.  Subsequent  recoveries  on  the  related  mortgage  loans  which  are  payable  to  the  Underlying
Certificates  relating to the Insured  Certificates will be allocated first to the Certificate Insurer for
payment of any Reimbursement  Amounts for such Distribution Date in respect of any Deficiency  Amount, but
only up to the amount actually paid by the Certificate Insurer on the related Insured Certificates.

Certificates before and after applying payments on such Distribution Date;

                  (iv)     the applicable record dates, accrual dates and actual Distribution Dates for the period;

                  (viii)   whether any exchanges of Exchangeable  Certificates  have taken place since the
preceding  Distribution  Date and, if applicable,  the names,  certificate  balances,  including  notional

and the aggregate amount in (a)(2) and (b)(y) of the definition of Deficiency Amount.

                  In the case of the  information  furnished  pursuant to clause  (ii) above,  the amounts
shall also be expressed as a dollar amount per $100,000 of principal face amount.

                  The Securities  Administrator  may make available each month,  to any interested  party,
the monthly statement to Certificateholders via the Securities  Administrator’s  website initially located
at  “www.ctslink.com.”  Assistance  in using  the  website  can be  obtained  by  calling  the  Securities
Administrator’s  customer  service  desk at (301)  815-6600.  Parties  that are  unable  to use the  above
distribution  option are  entitled to have a paper copy mailed to them via first class mail by calling the
Securities  Administrator’s  customer service desk and indicating such. The Securities Administrator shall
have the right to change the way such  reports are  distributed  in order to make such  distribution  more
convenient and/or more accessible to the parties,  and the Securities  Administrator  shall provide timely
and adequate notification to all parties regarding any such change.

                  In addition,  the Securities  Administrator  promptly will furnish to the Depositor and,
upon the  written  request  of a  Certificateholder,  the  Trustee  or the  Certificate  Insurer,  to such
Certificateholder,  the Trustee or the Certificate  Insurer,  copies of any written  notices,  statements,

                  The Securities  Administrator  shall be responsible  for preparing,  at its own expense,
and  filing in a timely  manner,  on behalf of the Trust  Fund and for the Trust  Fund as a grantor  trust
under the Code,  federal income tax and information  returns and reports with the Internal Revenue Service
(“IRS”)  and income tax  returns and  information  returns and reports of any other state or local  taxing
authority  as are  required to be so filed,  using a calendar  year as the taxable year of the Trust on an
accrual  basis.  The  Trustee  shall  sign  all  such  tax  returns  provided  to  it  by  the  Securities
Administrator.  The Depositor  shall provide the  Securities  Administrator  within 10 days of the Closing
Date all information  deemed necessary by the Securities  Administrator  to fulfill its obligations  under
this  paragraph.  The  Securities  Administrator  shall  furnish  to each  Certificateholder  at the  time

local law with  respect to the Trust Fund to enable  Certificateholders  to prepare  their tax returns and
will furnish  comparable  information to the IRS and other taxing  authorities as and when required by law
to do so.

                  The  Securities  Administrator  shall  provide to the  Depositor  access to all reports,

(a)      The Securities  Administrator  shall deliver (or otherwise  make  available) to the Depositor and
the Trustee not later than March 15th of each  calendar year  beginning in 2007, an Officer’s  Certificate
(an “Annual  Statement of Compliance”)  stating,  as to each signatory  thereof,  that (i) a review of the
activities  of the  Securities  Administrator  during the preceding  calendar year and of its  performance
under  this  Agreement  has  been  made  under  such  officer’s  supervision  and (ii) to the best of such
officer’s  knowledge,  based  on such  review,  the  Securities  Administrator  has  fulfilled  all of its
obligations  under this  Agreement in all material  respects  throughout  such year or applicable  portion
thereof,  or, if there  has been a  failure  to  fulfill  any such  obligation  in any  material  respect,
specifying  each such  failure  known to such  officer  and the nature  and status of the cure  provisions
thereof.  Such Annual Statement of Compliance shall contain no restrictions or limitations on its use.

(b)      Failure  of the  Securities  Administrator  to comply  with this  Section  3.09  (including  with
respect to the  timeframes  required in this Section)  which  failure  results in a failure to timely file
the related  Form 10-K,  shall,  upon  written  notice from the  Trustee at the written  direction  of the
Depositor,  constitute  a default,  and, in  addition  to whatever  rights the Trustee may have under this
Agreement and at law or equity or to damages,  including injunctive relief and specific  performance,  the
Trustee  may upon  notice  immediately  terminate  all of the rights  and  obligations  of the  Securities
Administrator  under this Agreement and in and to the  Underlying  Certificates  and the proceeds  thereof
without  compensating  the  Securities   Administrator  for  the  same  (but  subject  to  the  Securities
Administrator’s  right to  reimbursement of all amounts for which it is entitled to be reimbursed prior to
the date of  termination).  This paragraph  shall  supersede any other  provision in this Agreement or any
other agreement to the contrary.

Section 3.10.      Assessments of Compliance and Attestation Reports.

         Pursuant  to Rules  13a-18 and 15d-18 of the  Exchange  Act and Item 1122 of  Regulation  AB, the
Securities  Administrator (to the extent set forth in this Section) (the “Attesting  Party”) shall deliver
(or  otherwise  make  available) to the Depositor and the Trustee on or before March 15th of each calendar
year  beginning  in  2007,  a  report  regarding  the  Attesting  Party’s  assessment  of  compliance  (an
“Assessment of Compliance”)  with the Servicing  Criteria  applicable to it during the preceding  calendar
year.  The Assessment of Compliance, as set forth in Regulation AB, must contain the following:

         (a)      A  statement  by an  authorized  officer of the  Attesting  Party of its  authority  and
responsibility for assessing compliance with the Servicing Criteria applicable to the Attesting Party;

         (b)      A  statement  by an  authorized  officer  that the  Attesting  Party used the  Servicing
Criteria  identified in Exhibit C hereto to assess  compliance with the Servicing  Criteria  applicable to
the Attesting Party;

         (c)      An assessment by such officer of the Attesting  Party’s  compliance  with the applicable
Servicing Criteria for the period consisting of the preceding calendar year,  including  disclosure of any
material  instance of  noncompliance  with respect thereto during such period,  which  assessment shall be
based  on  the  activities  the  Attesting  Party  performs  with  respect  to   asset-backed   securities
transactions  taken as a whole  involving the Attesting  Party,  that are backed by the same asset type as
those backing the Underlying Certificates;

         (d)      A statement that a registered  public  accounting firm has issued an attestation  report
on the Attesting  Party’s  Assessment of Compliance  for the period  consisting of the preceding  calendar
year; and

         (e)      A statement as to which of the  Servicing  Criteria,  if any, are not  applicable to the
Attesting  Party,  which  statement  shall be based on the  activities  the Attesting  Party performs with
respect to asset-backed  securities  transactions taken as a whole involving the Attesting Party, that are
backed by the same asset type as those backing the Certificates.

         Such report at a minimum  shall  address each of the  Servicing  Criteria  specified on Exhibit C
hereto which are indicated as applicable to the Attesting Party.

         On or before March 15th of each  calendar  year  beginning  in 2007,  the  Attesting  Party shall
furnish  (or  otherwise  make  available)  to the  Depositor  and the  Trustee a report  (an  “Attestation
Report”) by a  registered  public  accounting  firm that  attests to, and  reports on, the  Assessment  of
Compliance  made by the  Attesting  Party,  as required by Rules 13a-18 and 15d-18 of the Exchange Act and
Item 1122(b) of Regulation  AB, which  Attestation  Report must be made in accordance  with  standards for
attestation reports issued or adopted by the Public Company Accounting Oversight Board.

         The Depositor  shall confirm that the  Assessment of Compliance  delivered to it addresses all of
the Servicing  Criteria set forth in Exhibit C and notify the Securities  Administrator of any exceptions.
Notwithstanding  the foregoing,  as to any  subcontractor,  an Assessment of Compliance is not required to
be delivered unless it is required as part of a Form 10-K with respect to the Trust Fund.

         Failure  of the  Securities  Administrator  to comply  with this  Section  3.10  (including  with
respect to the  timeframes  required in this Section)  which  failure  results in a failure to timely file
the related  Form 10-K,  shall,  upon  written  notice from the  Depositor,  constitute  a default and the
Trustee  shall,  in addition to whatever  rights the Trustee may have under this  Agreement  and at law or
equity or to damages,  including  injunctive  relief and  specific  performance,  upon notice  immediately
terminate all of the rights and  obligations of the Securities  Administrator  under this Agreement and in
and  to the  Underlying  Certificates  and  the  proceeds  thereof  without  compensating  the  Securities
Administrator  for the same (but subject to the Securities  Administrator’s  right to reimbursement of all
amounts  for which it is entitled  to be  reimbursed  prior to the date of  termination).  This  paragraph
shall supersede any other provision in this Agreement or any other agreement to the contrary.

Section 3.11.     Reports Filed with Securities and Exchange Commission.

         (a)      (i) (A)  Within  15 days  after  each  Distribution  Date,  for so long as the  Trust is
subject to Exchange Act reporting  requirements,  the Securities  Administrator  shall, in accordance with
industry  standards,  prepare and file with the Commission via the Electronic Data Gathering and Retrieval
System  (“EDGAR”),  a  Distribution  Report  on Form  10-D,  signed by the  Depositor,  with a copy of the
Monthly  Statement to be furnished by the  Securities  Administrator  to the  Certificateholders  for such
Distribution  Date;  provided that, the  Securities  Administrator  shall have received no later than five
(5) calendar days after the related  Distribution  Date,  all  information  required to be provided to the
Securities  Administrator  as described in clause  (a)(iv) below.  Any  disclosure  that is in addition to
the Monthly  Statement and that is required to be included on Form 10-D,  including the Form 10-D filed in
connection  with the Underlying  Series  (“Additional  Form 10-D  Disclosure”)  shall be,  pursuant to the
paragraph  immediately  below,  reported  by  the  parties  set  forth  on  Exhibit  D to  the  Securities
Administrator  and the Depositor and approved by the  Depositor,  and the  Securities  Administrator  will
have no duty or liability  for any failure  hereunder to  determine  or prepare any  Additional  Form 10-D
Disclosure  absent  such  reporting  (other  than in the case where the  Securities  Administrator  is the
reporting party as set forth in Exhibit D) and approval.

         (B) Within  five (5)  calendar  days after the  related  Distribution  Date,  (i) the parties set
forth in  Exhibit  D shall  be  required  to  provide,  pursuant  to  Section  3.11(a)(iv)  below,  to the
Securities  Administrator  and the Depositor,  to the extent known by a responsible  officer  thereof,  in
EDGAR-compatible  format,  or in such other form as otherwise agreed upon by the Securities  Administrator
and the  Depositor and such party,  the form and  substance of any  Additional  Form 10-D  Disclosure,  if
applicable and (ii) the Depositor will approve, as to form and substance,  or disapprove,  as the case may
be,  the  inclusion  of the  Additional  Form  10-D  Disclosure  on Form  10-D.  The  Depositor  shall  be
responsible for any reasonable fees and expenses  assessed or incurred by the Securities  Administrator in
connection with including any Form 10-D Disclosure Information on Form 10-D pursuant to this Section.

         (C) After preparing the Form 10-D, the Securities  Administrator  shall forward  electronically a
copy of the Form 10-D to the  Depositor  for review.  Within two Business Days after receipt of such copy,
but no later than the 12th  calendar  day after the  Distribution  Date  (provided  that,  the  Securities
Administrator  forwards a copy of the Form 10-D no later  than the 10th  calendar  after the  Distribution
Date),  the  Depositor  shall  notify the  Securities  Administrator  in writing  (which may be  furnished
electronically)  of any  changes  to or  approval  of such Form  10-D.  In the  absence  of receipt of any
written  changes or  approval,  the  Securities  Administrator  shall be entitled to assume that such Form
10-D is in final form and the  Securities  Administrator  may proceed with the filing of the Form 10-D. No
later than the 13th calendar day after the related  Distribution  Date, a duly  authorized  officer of the
Depositor  shall sign the Form 10-D and return an  electronic  or fax copy of such  signed Form 10-D (with
an original  executed hard copy to follow by overnight  mail) to the Securities  Administrator.  If a Form
10-D  cannot be filed on time or if a  previously  filed Form 10-D  needs to be  amended,  the  Securities
Administrator  shall follow the  procedures set forth in Section  3.11(a)(v).  Promptly (but no later than
one (1)  Business  Day)  after  filing  with the  Commission,  the  Securities  Administrator  shall  make
available  on its  internet  website  a final  executed  copy of each Form  10-D  filed by the  Securities
Administrator.  The  parties  to  this  Agreement  acknowledge  that  the  performance  by the  Securities
Administrator  of its  duties  under  Sections  3.11(a)(i)  and (v)  related  to the  timely  preparation,
execution  and filing of Form 10-D is  contingent  upon such parties  strictly  observing  all  applicable
deadlines in the  performance of their duties under such  Sections.  The  Securities  Administrator  shall
not have any  liability  for any loss,  expense,  damage,  claim  arising  out of or with  respect  to any
failure  to  properly  prepare  and timely  file such Form  10-D,  where  such  failure  results  from the
Securities  Administrator’s  inability or failure to receive,  on a timely basis, any information from any
other party hereto  needed to prepare,  arrange for execution or file such Form 10-D,  not resulting  from
its own negligence, bad faith or willful misconduct.

         Each of Form 10-D and Form 10-K requires the  registrant to indicate (by checking  “yes” or “no”)
that it “(1) has filed  all  reports  required  to be filed by  Section  13 or 15(d) of the  Exchange  Act
during the preceding 12 months (or for such shorter  period that the  registrant was required to file such
reports),  and (2) has been  subject to such  filing  requirements  for the past 90 days.”  The  Depositor
hereby represents to the Securities  Administrator  that the Depositor has filed all such required reports
during  the  preceding  12 months  and it has been  subject to such  filing  requirements  for the past 90
days.  The  Depositor  shall  notify the  Securities  Administrator  in  writing,  no later than the fifth
calendar day after the related  Distribution  Date with respect to the filing of a report on Form 10-D and
no later  than  March  15th with  respect  to the  filing of a report on Form  10-K,  if the answer to the
questions   should  be  “no.”  The   Securities   Administrator   shall  be   entitled  to  rely  on  such
representations in preparing, executing and/or filing any such report.

         (ii) (A) Within four (4) Business Days after the occurrence of an event  requiring  disclosure on
Form 8-K (each such event,  a  “Reportable  Event”),  for so long as the Trust is subject to Exchange  Act
reporting  requirements,  the  Securities  Administrator  shall  prepare and file, at the direction of the
Depositor,  on behalf of the Trust,  any Form 8-K, as required by the Exchange  Act;  provided  that,  the
Depositor  shall  prepare  and  file  the  initial  Form  8-K  in  connection  with  the  issuance  of the
Certificates.  Any disclosure or information  related to a Reportable Event or that is otherwise  required
to be included on Form 8-K,  including any Form 8-K filed in connection with the Underlying  Series (“Form
8-K  Disclosure  Information”)  shall be,  pursuant to the paragraph  immediately  below,  reported by the
parties set forth on Exhibit D to the  Securities  Administrator  and the  Depositor  and  approved by the
Depositor,  and the Securities  Administrator  will have no duty or liability for any failure hereunder to
determine or prepare any Additional  Form 10-D  Disclosure  absent such reporting  (other than in the case
where the Securities Administrator is the reporting party as set forth in Exhibit D) and approval.

         (B) For so long as the Trust is subject to the  Exchange  Act  reporting  requirements,  no later
than the  close of  business  New York  City  time on the 2nd  Business  Day  after  the  occurrence  of a
Reportable  Event  (i) the  parties  set  forth  in  Exhibit  D shall  be  required  pursuant  to  Section
3.11(a)(iv) below to provide to the Securities  Administrator and the Depositor,  to the extent known by a
responsible officer thereof,  in  EDGAR-compatible  format, or in such other form as otherwise agreed upon
by the Securities  Administrator  and the Depositor and such party, the form and substance of any Form 8-K
Disclosure  Information,  if applicable,  and (ii) the Depositor shall approve,  as to form and substance,
or disapprove,  as the case may be, the inclusion of the Form 8-K Disclosure  Information on Form 8-K. The
Depositor  shall be  responsible  for any  reasonable  fees  and  expenses  assessed  or  incurred  by the
Securities  Administrator  in connection  with including any Form 8-K  Disclosure  Information on Form 8-K
pursuant to this Section.

         (C) After preparing the Form 8-K, the Securities  Administrator  shall forward  electronically  a
copy of the Form 8-K to the  Depositor  for  review.  No later  than  noon New York  City  time on the 4th
Business Day after the Reportable  Event, a duly  authorized  officer of the Depositor shall sign the Form
8-K and return an electronic  or fax copy of such signed Form 8-K (with an original  executed hard copy to
follow by  overnight  mail) to the  Securities  Administrator.  Promptly,  but no later  than the close of
business on the 3rd Business Day after the  Reportable  Event,  the Depositor  shall notify the Securities
Administrator  in writing  (which may be furnished  electronically)  of any changes to or approval of such
Form 8-K filed by the  Securities  Administrator.  In the  absence of receipt  of any  written  changes or
approval,  the  Securities  Administrator  shall be entitled to assume that such Form 8-K is in final form
and the  Securities  Administrator  may  proceed  with the filing of the Form 8-K. If a Form 8-K cannot be
filed on time or if a previously filed Form 8-K needs to be amended,  the Securities  Administrator  shall
follow  the  procedures  set forth in Section  3.11(a)(v).  Promptly  (but no later than one (1)  Business
Day) after  filing  with the  Commission,  the  Securities  Administrator  shall,  make  available  on its
internet  website  a final  executed  copy of each  Form 8-K filed by the  Securities  Administrator.  The
parties to this Agreement  acknowledge that the performance by the Securities  Administrator of its duties
under this Section  3.11(a)(ii)  related to the timely  preparation,  execution  and filing of Form 8-K is
contingent  upon such parties  strictly  observing all  applicable  deadlines in the  performance of their
duties under this Section  3.11(a)(ii).  The  Securities  Administrator  shall have any  liability for any
loss, expense,  damage,  claim arising out of or with respect to any failure to properly prepare,  execute
and/or  timely  file such  Form 8-K,  where  such  failure  results  from the  Securities  Administrator’s
inability or failure to receive,  on a timely basis,  any  information  from any other party hereto needed
to prepare,  arrange for  execution  or file such Form 8-K, not  resulting  from its own  negligence,  bad
faith or willful misconduct.

         (iii) (A) Within 90 days after the end of each fiscal year of the Trust or such  earlier  date as
may be required by the Exchange  Act (the “10-K Filing  Deadline”)  (it being  understood  that the fiscal
year for the Trust ends on December 31st of each year),  commencing  in March 2007 and  thereafter so long
as the Trust is subject to  Exchange  Act  reporting  requirements,  the  Securities  Administrator  shall
prepare and file on behalf of the Trust a Form 10-K,  in form and  substance  as required by the  Exchange
Act.  Each such Form 10-K shall  include the  following  items,  in each case to the extent they have been
delivered to the Securities  Administrator  within the applicable time frames set forth in this Agreement,
(I) an annual  compliance  statement for the Securities  Administrator,  as described  under Section 3.09,
(II)(A)  the annual  report on  assessment  of  compliance  with  Servicing  Criteria  for the  Securities
Administrator,  as described  under Section  3.10,  and (B) if any such report on assessment of compliance
with Servicing  Criteria  described under Section 3.10 identifies any material  instance of noncompliance,
disclosure  identifying such instance of noncompliance,  or if any such report on assessment of compliance
with  Servicing  Criteria  described  under  Section 3.10 is not included as an exhibit to such Form 10-K,
disclosure that such report is not included and an explanation  why such report is not included,  (III)(A)
the registered public accounting firm attestation  report for the Securities  Administrator,  as described
under Section 3.10, and (B) if any registered  public  accounting firm attestation  report described under
Section 3.10 identifies any material  instance of noncompliance,  disclosure  identifying such instance of
noncompliance,  or if any such registered public accounting firm attestation  report is not included as an
exhibit to such Form  10-K,  disclosure  that such  report is not  included  and an  explanation  why such
report is not included,  and (IV) a Sarbanes-Oxley  Certification as described in Section 3.11 (a)(iii)(D)
below (provided,  however, that the Securities  Administrator,  at its discretion,  may omit from the Form
10-K any  annual  compliance  statement,  assessment  of  compliance  or  attestation  report  that is not
required to be filed with such Form 10-K pursuant to Regulation  AB). Any  disclosure  or  information  in
addition to (I) through (IV) above that is required to be included on Form 10-K,  including  the Form 10-K
filed in connection with the Underlying Series  (“Additional Form 10-K Disclosure”)  shall be, pursuant to
the  paragraph  immediately  below,  reported  by the  parties  set forth on  Exhibit D to the  Securities
Administrator  and the Depositor and approved by the  Depositor,  and the  Securities  Administrator  will
have no duty or liability  for any failure  hereunder to  determine  or prepare any  Additional  Form 10-K
Disclosure  absent  such  reporting  (other  than in the case where the  Securities  Administrator  is the
reporting party as set forth in Exhibit D) and approval.

         (B) No later  than  March  15th of each  year  that the  Trust is  subject  to the  Exchange  Act
reporting  requirements,  commencing in 2007,  (i) the parties set forth in Exhibit D shall be required to
provide pursuant to Section  3.11(a)(iv) below to the Securities  Administrator and the Depositor,  to the
extent known by a  responsible  officer  thereof,  in  EDGAR-compatible  format,  or in such other form as
otherwise  agreed upon by the  Securities  Administrator  and the Depositor  and such party,  the form and
substance of any Additional Form 10-K Disclosure,  if applicable,  and (ii) the Depositor will approve, as
to form and  substance,  or  disapprove,  as the case may be, the  inclusion of the  Additional  Form 10-K
Disclosure  on Form  10-K.  The  Depositor  shall be  responsible  for any  reasonable  fees and  expenses
assessed  or  incurred  by the  Securities  Administrator  in  connection  with  including  any Form  10-K
Disclosure information on Form 10-K pursuant to this Section.

         (C) After preparing the Form 10-K, the Securities  Administrator  shall forward  electronically a
copy of the Form 10-K to the  Depositor  for review.  Within  three  Business  Days after  receipt of such
copy, but no later than March 25th, the Depositor  shall notify the  Securities  Administrator  in writing
(which may be furnished  electronically)  of any changes to or approval of such Form 10-K.  In the absence
of receipt of any written changes or approval,  the Securities  Administrator  shall be entitled to assume
that such Form 10-K is in final form and the Securities  Administrator  may proceed with the filing of the
Form 10-K.  No later than the close of business  Eastern  Standard  time on the 4th  Business Day prior to
the 10-K  Filing  Deadline,  a senior  officer  of the  Depositor  shall  sign the Form 10-K and return an
electronic  or fax copy of such  signed  Form  10-K  (with an  original  executed  hard  copy to follow by
overnight  mail)  to the  Securities  Administrator.  If a Form  10-K  cannot  be  filed  on  time or if a
previously filed Form 10-K needs to be amended,  the Securities  Administrator  will follow the procedures
set forth in Section  3.11(a)(v).  Promptly  (but no later than one (1)  Business  Day) after  filing with
the  Commission,  the  Securities  Administrator  shall make  available  on its  internet  website a final
executed  copy of each Form 10-K filed by the  Securities  Administrator.  The  parties to this  Agreement
acknowledge  that  the  performance  by  the  Securities   Administrator  of  its  duties  under  Sections
3.11(a)(iii)  and (v) related to the timely  preparation,  execution and filing of Form 10-K is contingent
upon such parties  strictly  observing all applicable  deadlines in the  performance of their duties under
such  Sections  and  Sections  3.09 and Section  3.10.  The  Securities  Administrator  shall not have any
liability for any loss, expense,  damage,  claim arising out of or with respect to any failure to properly
prepare,  execute  and/or  timely file such Form 10-K,  where such  failure  results  from the  Securities
Administrator’s  inability or failure to receive,  on a timely basis, any information from any other party
hereto  needed to prepare,  arrange  for  execution  or file such Form 10-K,  not  resulting  from its own
negligence, bad faith or willful misconduct.

         (D) Each Form 10-K shall include a certification (the  “Sarbanes-Oxley  Certification”)  required
to be included  therewith in compliance with Item  601(b)(31)(ii) of Regulation S-K, which shall be signed
by the Certifying  Person and delivered to the Securities  Administrator  no later than March 15th of each
year in which the Trust is subject to the  reporting  requirements  of the Exchange  Act.  The  Securities
Administrator  shall provide to the Depositor,  as the Person who signs the  Sarbanes-Oxley  Certification
(the  “Certifying  Person”),  by March 10th of each year in which the Trust is  subject  to the  reporting
requirements  of the  Exchange  Act and  otherwise  within a  reasonable  period of time upon  request,  a
certification  (a  “Back-Up  Certification”),  in the form  attached  hereto as  Exhibit B, upon which the
Certifying  Person,  the entity for which the  Certifying  Person  acts as an officer,  and such  entity’s
officers,  directors and Affiliates  (collectively  with the Certifying Person,  “Certification  Parties”)
can  reasonably  rely. A senior officer of the Depositor  shall serve as the  Certifying  Person on behalf
of the Trust.

         (iv) With respect to any Additional  Form 10-D  Disclosure,  Additional  Form 10-K  Disclosure or
any Form 8-K Disclosure  Information  (collectively,  the “Additional  Disclosure”)  relating to the Trust
Fund, the Securities  Administrator’s  obligation to include such Additional Information in the applicable
Exchange  Act  report is  subject  to  receipt  from the  entity  that is  indicated  in  Exhibit D as the
responsible  party for providing  that  information,  if other than the Securities  Administrator,  as and
when required as described in Section  3.11(a)(i)  through (iii) above.  Such Additional  Disclosure shall
be accompanied  by a notice  substantially  in the form of Exhibit E. Each of the Sponsor,  the Securities
Administrator  and the  Depositor  hereby agrees to notify and provide to the extent known to the Sponsor,
the  Securities  Administrator  and the Depositor all  Additional  Disclosure  relating to the Trust Fund,
with respect to which such party is indicated in Exhibit E as the  responsible  party for  providing  that
information.  The  Depositor  shall be  responsible  for any  reasonable  fees and  expenses  assessed  or
incurred  by  the  Securities  Administrator  in  connection  with  including  any  Additional  Disclosure
information pursuant to this Section.

         So long as the  Depositor  is subject to the  reporting  requirements  of the  Exchange  Act with
respect to the Trust Fund,  the Trustee  shall notify the  Securities  Administrator  and the Depositor of
any  bankruptcy or  receivership  with respect to the Trustee or of any  proceedings of the type described
under Item 1117 of  Regulation  AB that have  occurred  as of the  related  Due  Period,  together  with a
description  thereof,  no later than the date on which  such  information  is  required  of other  parties
hereto as set forth under this  Section  3.11.  In  addition,  the  Trustee  shall  notify the  Securities
Administrator  and the Depositor of any affiliations or relationships  that develop after the Closing Date
between the Trustee and the Depositor,  the Sponsor or the Securities  Administrator of the type described
under Item 1119 of Regulation  AB,  together with a description  thereof,  no later than the date on which
such  information  is required of other parties  hereto as set forth under this Section  3.11.  Should the
identification  of any  of  the  Depositor,  the  Sponsor  or the  Securities  Administrator  change,  the
Depositor shall promptly notify the Trustee.

         (v) (A) On or prior to January 30th of the first year in which the  Securities  Administrator  is
able to do so  under  applicable  law,  the  Securities  Administrator  shall  prepare  and file a Form 15
relating to the automatic suspension of reporting in respect of the Trust under the Exchange Act.

         (B) In the event that the Securities  Administrator  is unable to timely file with the Commission
all or any required  portion of any Form 8-K, 10-D or 10-K required to be filed by this Agreement  because
required  disclosure  information  was either not  delivered  to it or  delivered to it after the delivery
deadlines  set forth in this  Agreement  or for any  other  reason,  the  Securities  Administrator  shall
promptly  notify  the  Depositor.  In the case of Form 10-D and 10-K,  the  Depositor  and the  Securities
Administrator  shall  cooperate  to prepare  and file a Form  12b-25 and a 10-DA and 10-KA as  applicable,
pursuant  to Rule  12b-25 of the  Exchange  Act.  In the case of Form 8-K,  the  Securities  Administrator
will,  upon receipt of all required Form 8-K  Disclosure  Information  and upon the approval and direction
of the  Depositor,  include  such  disclosure  information  on the next Form  10-D.  In the event that any
previously  filed  Form  8-K,  10-D or 10-K  needs  to be  amended,  and  such  amendment  relates  to any
Additional  Disclosure,  the Securities  Administrator shall notify the Depositor and the parties affected
thereby and such parties will cooperate to prepare any necessary  Form 8-K,  10-DA or 10-KA.  Any Form 15,
Form 12b-25 or any  amendment to Form 8-K,  10-D or 10-K shall be signed by a duly  authorized  officer of
the Depositor.  The parties hereto  acknowledge  that the  performance by the Depositor and the Securities
Administrator  of  their  respective  duties  under  this  Section   3.11(a)(v)   related  to  the  timely
preparation,  execution  and filing of Form 15, a Form 12b-25 or any  amendment to Form 8-K,  10-D or 10-K
is  contingent  upon the  Depositor  timely  performing  its duties  under this  Section.  The  Securities
Administrator  shall not have any liability for any loss,  expense,  damage,  claim arising out of or with
respect to any failure to properly  prepare,  execute  and/or timely file any such Form 15, Form 12b-25 or
any amendments to Form 8-K, 10-D or 10-K,  where such failure results from the Securities  Administrator’s
inability or failure to receive,  on a timely basis,  any  information  from any other party hereto needed
to prepare,  arrange for  execution or file such Form 15, Form 12b-25 or any  amendments to Form 8-K, 10-D
or 10-K, not resulting from its own negligence, bad faith or willful misconduct.

         The  Depositor  agrees to promptly  furnish to the  Securities  Administrator,  from time to time
upon request,  such further  information,  reports and financial  statements within its control related to
this  Agreement  and  the  Underlying  Certificates  as  the  Securities  Administrator  reasonably  deems
appropriate to prepare and file all necessary  reports with the Commission.  The Securities  Administrator
shall  have no  responsibility  to file any  items  other  than  those  specified  in this  Section  3.11;
provided,  however,  the Securities  Administrator  shall  cooperate with the Depositor in connection with
any  additional  filings  with  respect  to the Trust  Fund as the  Depositor  deems  necessary  under the
Exchange  Act.  Fees and  expenses  incurred  by the  Securities  Administrator  in  connection  with this
Section 3.11 shall not be reimbursable from the Trust Fund.

         (b)      The Securities  Administrator  shall  indemnify and hold harmless the Depositor and each
of its  officers,  directors  and  affiliates  from and  against any losses,  damages,  penalties,  fines,
forfeitures,  reasonable  and  necessary  legal fees and  related  costs,  judgments  and other  costs and
expenses  arising  out of or based  upon a breach  of the  Securities  Administrator’s  obligations  under
Sections  3.09,  3.10  and  3.11 or the  Securities  Administrator’s  negligence,  bad  faith  or  willful
misconduct in connection  therewith.  In addition,  the Securities  Administrator shall indemnify and hold
harmless the Depositor and each of its  respective  officers,  directors and  affiliates  from and against
any losses,  damages,  penalties,  fines,  forfeitures,  reasonable  and necessary  legal fees and related
costs,  judgments  and other costs and expenses  arising out of or based upon (i) any untrue  statement or
alleged  untrue  statement  of any  material  fact  contained  in any  Back-Up  Certification,  any Annual
Statement of  Compliance,  any  Assessment  of  Compliance or any  Additional  Disclosure  provided by the
Securities  Administrator  on its  behalf  pursuant  to  Section  3.09,  3.10  or  3.11  (the  “Securities
Administrator  Information”),  or (ii) any omission or alleged  omission to state  therein a material fact
required to be stated therein or necessary to make the statements  therein,  in light of the circumstances
in which they were made, not misleading;  provided, by way of clarification,  that this paragraph shall be
construed  solely  by  reference  to the  Securities  Administrator  Information  and  not  to  any  other
information  communicated  in connection with the  Certificates,  without regard to whether the Securities
Administrator  Information  or any portion  thereof is presented  together  with or  separately  from such
other information.

         The Depositor  shall  indemnify and hold harmless the  Securities  Administrator  and each of its
officers,  directors and affiliates from and against any losses, damages,  penalties,  fines, forfeitures,
reasonable  and necessary  legal fees and related  costs,  judgments and other costs and expenses  arising
out of or based upon a breach of the  obligations of the Depositor  under Sections 3.09,  3.10 and 3.11 or
the Depositor’s  negligence,  bad faith or willful misconduct in connection  therewith.  In addition,  the
Depositor  shall  indemnify  and hold harmless the  Securities  Administrator  and each of its  respective
officers,  directors and affiliates from and against any losses, damages,  penalties,  fines, forfeitures,
reasonable  and necessary  legal fees and related  costs,  judgments and other costs and expenses  arising
out of or based upon (i) any untrue  statement or alleged untrue  statement of any material fact contained
in any  Additional  Disclosure  provided by the  Depositor  that is required to be filed  pursuant to this
Section 3.11 (the “Depositor  Information”),  or (ii) any omission or alleged  omission to state therein a
material fact required to be stated therein or necessary to make the statements  therein,  in light of the
circumstances  in which they were made,  not  misleading;  provided,  by way of  clarification,  that this
paragraph  shall be  construed  solely by reference to the  Depositor  Information  that is required to be
filed and not to any other information  communicated in connection with the  Certificates,  without regard
to whether the  Depositor  Information  or any portion  thereof is presented  together  with or separately
from such other information.

         If the  indemnification  provided for herein is unavailable or  insufficient to hold harmless the
Depositor or the Securities  Administrator,  as applicable,  then the defaulting party, in connection with
any conduct for which it is providing  indemnification  under this Section  3.11(b),  agrees that it shall
contribute to the amount paid or payable by the other parties as a result of the losses,  claims,  damages
or liabilities  of the other party in such  proportion as is appropriate to reflect the relative fault and
the relative benefit of the respective parties.

         The  indemnification  provisions set forth in this Section  3.11(b) shall survive the termination
of this Agreement or the termination of any party to this Agreement.

         (c)      Failure of the  Securities  Administrator  to comply with this Section  3.11  (including
with respect to the  timeframes  required in this Section)  which  failure  results in a failure to timely
file the related Form 10-K,  shall,  upon written notice from the Trustee at the written  direction of the
Depositor,  constitute  a default and the Trustee at the written  direction  of the  Depositor  shall,  in
addition  to  whatever  rights  the  Trustee  may have  under  this  Agreement  and at law or equity or to
damages,  including injunctive relief and specific  performance,  upon notice immediately terminate all of
the rights  and  obligations  of the  Securities  Administrator  under  this  Agreement  and in and to the
Underlying  Certificates and the proceeds thereof without  compensating the Securities  Administrator  for
the same (but subject to the Securities  Administrator’s  right to  reimbursement of all amounts for which
it is entitled to be reimbursed  prior to the date of  termination).  This paragraph  shall  supersede any
other  provision  in this  Agreement  or any other  agreement  to the  contrary.  In  connection  with the
termination  of the  Securities  Administrator  pursuant to this  Section  3.11(c),  the Trustee  shall be
entitled to  reimbursement  of all costs and expenses  associated with such  termination.  Notwithstanding
anything  to the  contrary  in this  Agreement,  no default  by the  Securities  Administrator  shall have
occurred with respect to any failure to properly  prepare,  execute  and/or timely file any report on Form
8-K,  Form 10-D or Form 10-K,  any Form 15 or Form  12b-25 or any  amendments  to Form 8-K,  10-D or 10-K,
where such  failure  results from the  Securities  Administrator’s  inability or failure to receive,  on a
timely basis,  any  information  from any other party hereto  needed to prepare,  arrange for execution or
file any such  report,  Form or  amendment,  and does not  result  from its own  negligence,  bad faith or
willful misconduct.

         (d)      This Section 3.11 may be amended  without the consent of the  Certificateholders  or the
Certificate Insurer.

         (e)       Any report,  notice or notification to be delivered by the Securities  Administrator  to
the  Depositor  pursuant to this Section 3.11,  may be delivered via email to  RegABNotifications@bear.com
or, in the case of a notification, telephonically by calling Reg AB Compliance Manager at 212-272-7525.

Section 3.12.      The Policy.

         (a)  On  or  prior  to  the  Closing  Date,  the  Securities  Administrator  shall  cause  to  be
established  and  maintained  the  Policy  Account,   into  which  amounts   received  by  the  Securities
Administrator  pursuant to the Policy shall be  deposited  for the benefit of the Group V, Group VI, Group
VII, Group VIII or Group IX  Certificates,  as applicable.  The Policy Account may be a sub-account of the
Certificate  Account.  Amounts on deposit in the Policy  Account  shall not be  invested  and shall not be
held in an interest-bearing account.

         (b)  As soon as  possible,  and in no event later than 12:00 noon New York time on the second
Business Day immediately  preceding any Distribution Date, the Securities  Administrator shall furnish the
Certificate  Insurer with a completed  Notice in the form set forth as Exhibit A to the Endorsement to the
Policy in the event that the Available Funds for a Certificate  Group of the Insured  Certificates  (other
than any amounts in respect of Insured  Amounts) are  insufficient to pay Current Interest with respect to
the Group V,  Group VI,  Group VII,  Group VIII or Group IX  Certificateholders,  as  applicable,  on such
Distribution Date; provided,  however,  that if such Distribution Date is the Final Distribution Date, the
Notice shall also include the outstanding  Current  Principal Amounts of the Group V, Group VI, Group VII,
Group VIII or Group IX  Certificates,  after  giving  effect to all  payments of principal on the Group V,
Group VI, Group VII,  Group VIII or Group IX  Certificates  on such Final  Distribution  Date,  other than
pursuant to the Policy.  The Notice  shall  specify the amount of Insured  Amounts and shall  constitute a
claim for an Insured Amount pursuant to the Policy.

         (c)  Upon receipt of an Insured  Amount in  accordance  with the Policy from the  Certificate
Insurer on behalf of the Holders of the Insured Certificates,  the Securities  Administrator shall deposit
such  Insured  Amount into the Policy  Account.  On or prior to each  Distribution  Date,  the  Securities
Administrator  shall  transfer  amounts on deposit in the Policy  Account to the  Certificate  Account and
shall distribute such Insured Amounts pursuant to Section 3.05.

         The  Securities  Administrator  shall  include  on each  Distribution  Date any  Insured  Amounts
received  by it from or on behalf of the  Certificate  Insurer  for such  Distribution  Date in the amount
distributed to the Holders of the Insured  Certificates  pursuant to Section 3.05. If on any  Distribution
Date the Securities  Administrator  determines that the Certificate Insurer has paid more under the Policy
than is required by the terms thereof,  the Securities  Administrator  shall promptly return any excess to
the Certificate Insurer.

         (d)   (i) The Securities  Administrator  shall receive as  attorney-in-fact  of the Holders of
the Insured  Certificates  any Insured Amount  delivered to it by the  Certificate  Insurer for payment to
such Holders and (ii) the Securities  Administrator  shall  distribute such Insured Amount to such Holders
as set forth in Section 3.05.  Insured  Amounts  disbursed by the Securities  Administrator  from proceeds
of  the  Policy  shall  not  be  considered  payment  by the  Trust  Fund  with  respect  to  the  Insured
Certificates,  nor shall such  disbursement of Insured Amounts discharge the obligations of the Trust Fund
with respect to the amounts  thereof,  and the  Certificate  Insurer shall become owner of such amounts to
the extent  covered  by such  Insured  Amounts as the deemed  assignee  of such  Holders.  The  Securities
Administrator  hereby agrees on behalf of the Holders of the Insured  Certificates  (and each such Holder,
by its acceptance of its Insured  Certificates,  hereby agrees) for the benefit of the Certificate Insurer
that, to the extent the  Certificate  Insurer pays any Insured  Amount,  either directly or indirectly (as
by paying through the Securities Administrator),  to the Holder of a Insured Certificate,  the Certificate
Insurer  will be entitled to be  subrogated  to any rights of such Holder to receive the amounts for which
such  Insured  Amount was paid,  to the  extent of such  payment,  and will be  entitled  to  receive  the
Reimbursement Amount as set forth in Section 3.05.

         (e)   At the end of the  Term  of the  Policy  (as  defined  in the  Policy),  the  Securities
Administrator shall return the Policy to the Certificate Insurer for cancellation.

         (f)   Upon  its  becoming  aware  of  the  termination  of  the  Trust  Fund,  the  Securities
Administrator shall promptly notify the Certificate Insurer of such Termination.

         (g)   The Trustee shall  promptly  notify the  Certificate  Insurer of either of the following
as to which it has actual  knowledge:  (A) the  commencement of any proceeding by or against the Depositor
commenced  under the  United  States  bankruptcy  code or any  other  applicable  bankruptcy,  insolvency,
receivership,  rehabilitation or similar law (an “Insolvency  Proceeding”) and (B) the making of any claim
in  connection  with any  Insolvency  Proceeding  seeking  the  avoidance  as a  preferential  transfer (a
“Preference  Claim”) of any distribution made with respect to the Group V, Group VI, Group VII, Group VIII
and Group IX  Certificates  as to which it has  actual  knowledge.  Each  Holder  of a Group V,  Group VI,
Group VII,  Group VIII and Group IX  Certificate,  by its purchase of Group V, Group VI, Group VII,  Group
VIII and Group IX  Certificates,  and the Trustee hereby agrees that the  Certificate  Insurer (so long as
no  Certificate  Insurer  Default  exists)  may at any time  during  the  continuation  of any  proceeding
relating to a Preference Claim direct all matters relating to such Preference  Claim,  including,  without
limitation,  (i) the direction of any appeal of any order  relating to any  Preference  Claim and (ii) the
posting of any surety,  supersedes or  performance  bond pending any such appeal.  In addition and without
limitation  of the  foregoing,  the  Certificate  Insurer shall be subrogated to the rights of the Trustee
and each Holder of a Group V, Group VI, Group VII, Group VIII or Group IX  Certificates  in the conduct of
any Preference Claim,  including,  without limitation,  all rights of any party to an adversary proceeding
action with respect to any court order issued in connection with any such Preference Claim.

         (h)   The Securities  Administrator  shall  designate a "Certificate  Insurer  Contact Person"
who shall be available to the Certificate  Insurer to provide  reasonable access to information  regarding
the Group V, Group VI, Group VII, Group VIII and Group IX Certificates.

         (i)   The  Securities  Administrator  shall make  available  to the  Certificate  Insurer  the
reports  prepared  pursuant to Sections 3.09 and 3.11 and will send to the  Certificate  Insurer copies of
any  written  communications  sent by the  Securities  Administrator  to Holders of the Group V, Group VI,
Group VII,  Group VIII or Group IX  Certificates,  in each case at the same time such reports,  statements
and communications are otherwise sent.

         (j)   With  respect to this  Section  3.12,  the terms  “Receipt”  and  “Received”  shall mean
actual  delivery to the  Certificate  Insurer,  if any,  prior to 12:00 p.m., New York time, on a Business
Day;  delivery  either on a day that is not a Business  Day or after 12:00 p.m.,  New York time,  shall be
deemed to be Receipt on the next  succeeding  Business Day. If any notice or  certificate  given under the
Policy by the Securities  Administrator  is not in proper form or is not properly  completed,  executed or
delivered,  it shall be deemed not to have been  Received.  The  Certificate  Insurer  shall  promptly  so
advise the Securities Administrator and the Securities Administrator may submit an amended notice.

         (k)   All  references  herein to the  ratings  assigned  to the Group V, Group VI,  Group VII,
Group VIII and Group IX  Certificates  and to the  interests  of any  Certificateholders  shall be without
regard to the Policy.

                                                ARTICLE IV

                                             THE CERTIFICATES

Section 4.01.    The Certificates.

(a)      The  Depository,  the  Depositor  and the  Securities  Administrator  have  entered into a letter
agreement dated as of September 29, 2006 (the  “Depository  Agreement”).  Except as provided in Subsection
4.01(b),  the  Certificates  shall at all times remain  registered  in the name of the  Depository  or its
nominee  and  at all  times:  (i)  registration  of  such  Certificates  may  not  be  transferred  by the
Securities  Administrator  except to a successor  to the  Depository;  (ii)  ownership  and  transfers  of
registration  of such  Certificates on the books of the Depository  shall be governed by applicable  rules
established by the  Depository;  (iii) the Depository  may collect its usual and customary  fees,  charges
and expenses from its  Depository  Participants;  (iv) the  Securities  Administrator  shall deal with the
Depository  as  representative  of the  Certificate  Owners  for  purposes  of  exercising  the  rights of
Certificateholders   under  this   Agreement,   and  requests  and   directions  for  and  votes  of  such
representative  shall  not be  deemed  to be  inconsistent  if they are made  with  respect  to  different
Certificate  Owners;  and (v) the  Securities  Administrator  may rely and  shall  be fully  protected  in
relying upon information furnished by the Depository with respect to its Depository Participants.

                  All transfers by Certificate  Owners of  Certificates  shall be made in accordance  with
the procedures  established by the Depository  Participant or brokerage firm representing such Certificate
Owners.  Each  Depository   Participant  shall  only  transfer   Certificates  of  Certificate  Owners  it
represents or of brokerage  firms for which it acts as agent in accordance  with the  Depository’s  normal
procedures.

(b)      If (i)(A) the Depositor  advises the Securities  Administrator  in writing that the Depository is
no  longer  willing  or  able  to  properly  discharge  its  responsibilities  as  Depository  and (B) the
Securities  Administrator  or the  Depositor is unable to locate a qualified  successor  within 30 days or
(ii) after the occurrence and  continuation of a default  hereunder,  the  Certificate  Owners of not less
than 51% of the  Percentage  Interests of the  Certificates  advise the Securities  Administrator  and the
Depository in writing through the depository  participants  that the  continuation of a book-entry  system
with  respect to the  Certificates  through the  Depository  (or its  successor)  is no longer in the best
interests of the Certificate Owners,  then the Securities  Administrator shall request that the Depository
notify all Certificate  Owners of the occurrence of any such event and of the  availability of definitive,
fully  registered  Certificates  (the  “Definitive  Certificates”)  to Certificate  Owners  requesting the
same. Upon surrender to the Securities  Administrator of the  Certificates by the Depository,  accompanied
by registration  instructions from the Depository for  registration,  the Securities  Administrator  shall
issue the  Definitive  Certificates.  Neither the  Depositor  nor the  Securities  Administrator  shall be
liable  for any  delay in  delivery  of such  instructions  and may  conclusively  rely on,  and  shall be
protected in relying on, such instructions.

(c)      The  Certificates  shall be  substantially  in the  forms set  forth in  Exhibit  A  hereto.  The
Certificates  shall be executed  by manual  signature  on behalf of the  Securities  Administrator  in its
capacity  as  securities  administrator  hereunder  by an  authorized  officer.  Certificates  bearing the
manual or facsimile  signatures of individuals  who were at any time the proper officers of the Securities
Administrator  shall be entitled to all benefits under this Agreement,  subject to the following sentence,
notwithstanding  that such  individuals  or any of them have  ceased  to hold  such  offices  prior to the
authentication  and  delivery  of such  Certificates  or did not  hold  such  offices  at the date of such
Certificates.  No Certificate  shall be entitled to any benefit under this Agreement,  or be valid for any
purpose,  unless there appears on such  Certificate a certificate of  authentication  substantially in the
form provided for herein executed by the Certificate  Registrar by manual signature,  and such certificate
upon any Certificate shall be conclusive evidence,  and the only evidence,  that such Certificate has been
duly  authenticated  and  delivered  hereunder.  All  Certificates  shall  be  dated  the  date  of  their
authentication.

                  Pending the preparation of Definitive  Certificates,  the Securities  Administrator  may
sign  and  the  Certificate   Registrar  may  authenticate   temporary   Certificates  that  are  printed,
lithographed or typewritten,  in authorized denominations for Certificates,  substantially of the tenor of
the  Definitive  Certificates  in lieu of which  they are  issued  and with such  appropriate  insertions,
omissions,  substitutions  and other variations as the officers or authorized  signatories  executing such
Certificates  may  determine,  as  evidenced  by  their  execution  of  such  Certificates.  If  temporary
Certificates  are  issued,  the  Depositor  will cause  Definitive  Certificates  to be  prepared  without
unreasonable  delay. After the preparation of Definitive  Certificates,  the temporary  Certificates shall
be exchangeable  for Definitive  Certificates  upon surrender of the temporary  Certificates at the office
of the Securities  Administrator,  without charge to the Holder.  Upon surrender for  cancellation  of any
one or  more  temporary  Certificates,  the  Securities  Administrator  shall  sign  and  the  Certificate
Registrar  shall  authenticate  and deliver in exchange  therefor a like aggregate  principal  amount,  in
authorized  denominations,  of Definitive  Certificates.  Until so exchanged,  such temporary Certificates
shall in all respects be entitled to the same benefits as Definitive Certificates.

(d)      The Certificates  will be initially  registered as a single  Certificate held by a nominee of the
Depository,  and beneficial  interests will be held by investors through the book-entry  facilities of the
Depository in minimum denominations of $100,000 and increments of $1 in excess thereof.

Section 4.02.    Registration of Transfer and Exchange of Certificates.

(a)      At all times  during the term of this  Agreement,  there shall be  maintained  at the office of a
registrar  (the  “Certificate  Registrar”) a register (the  “Certificate  Register”) in which,  subject to
such reasonable  regulations as the Certificate  Registrar may prescribe,  the Certificate Registrar shall
provide for the  registration  of  Certificates  and of transfers and exchanges of  Certificates as herein
provided.  The  Securities  Administrator  is initially  appointed (and hereby agrees to act in accordance
with the  terms  hereof)  as  Certificate  Registrar  for the  purpose  of  registering  Certificates  and
transfers and exchanges of Certificates as herein  provided.  For so long as the Securities  Administrator
acts  as  Certificate  Registrar,  its  Corporate  Trust  Office  shall  constitute  the  offices  of  the
Certificate  Registrar maintained for such purposes.  The Certificate  Registrar may appoint, by a written
instrument  delivered to the Depositor,  any other bank or trust company to act as  Certificate  Registrar
under  such  conditions  as the  predecessor  Certificate  Registrar  may  prescribe,  provided  that  the
predecessor  Certificate  Registrar  shall  not be  relieved  of any of  its  duties  or  responsibilities
hereunder  by reason of such  appointment.  If the  Securities  Administrator  resigns  or is  removed  in
accordance with the terms hereof,  the successor  Securities  Administrator  shall immediately  succeed to
its predecessor’s duties as Certificate  Registrar.  The Depositor and the Securities  Administrator shall
have the right to inspect the  Certificate  Register or to obtain a copy thereof at all reasonable  times,
and to rely conclusively  upon a certificate of the Certificate  Registrar as to the information set forth
in the Certificate Register.

                  Every  Certificateholder  agrees  with  the  Certificate  Registrar  and the  Securities
Administrator  that neither the  Certificate  Registrar,  nor the Securities  Administrator  shall be held
accountable  by reason of the  disclosure  of any such  information  as to the names and  addresses of the
Certificateholders hereunder, regardless of the source from which such information was derived.

(b)      Subject to the  preceding  subsections,  upon  surrender  for  registration  of  transfer  of any
Certificate  at the offices of the  Certificate  Registrar  maintained  for such purpose,  the  Securities
Administrator  shall execute and the Certificate  Registrar shall authenticate and deliver, in the name of
the designated  transferee or transferees,  one or more new  Certificates  of a like aggregate  Percentage
Interest.

(c)      At the  option of any  Holder,  its  Certificates  may be  exchanged  for other  Certificates  of
authorized  denominations of a like aggregate Percentage  Interest,  upon surrender of the Certificates to
be  exchanged  at the offices of the  Certificate  Registrar  maintained  for such  purpose.  Whenever any
Certificates  are so  surrendered  for  exchange,  the  Securities  Administrator  shall  execute  and the
Certificate Registrar shall authenticate and deliver the Certificates which the  Certificateholder  making
the exchange is entitled to receive.

(d)      Every  Certificate  presented or  surrendered  for transfer or exchange  shall (if so required by
the Securities  Administrator) be duly endorsed by, or be accompanied by a written  instrument of transfer
in the form  satisfactory  to the  Securities  Administrator  duly executed by, the Holder  thereof or his
attorney duly authorized in writing.

(e)      No  service  charge  shall be made for any  transfer  or  exchange  of  Certificates  (except  as
provided in Section  4.05 with  respect to the  exchange of any  Exchangeable  Certificates  or  Exchanged
Certificates),  but the Securities  Administrator may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any transfer or exchange of Certificates.

(f)      All  Certificates  surrendered  for transfer and exchange  shall be destroyed by the  Certificate
Registrar without liability on its part.

Section 4.03.     Mutilated, Destroyed, Lost or Stolen Certificates.

                  If (i) any mutilated  Certificate is surrendered to the  Certificate  Registrar,  or the
Securities  Administrator  and the Certificate  Registrar  receive  evidence to their  satisfaction of the
destruction,  loss or theft of any Certificate,  and (ii) (except in the case of a mutilated  Certificate)
there  is  delivered  to the  Securities  Administrator  and the  Certificate  Registrar  such  agreement,
security or indemnity as may be required by them to save each of them  harmless,  then,  in the absence of
notice to the  Securities  Administrator  or the  Certificate  Registrar  that such  Certificate  has been
acquired  by a bona fide  purchaser,  the  Securities  Administrator  shall  execute  and the  Certificate
Registrar shall  authenticate  and deliver,  in exchange for or in lieu of any such mutilated,  destroyed,
lost or stolen  Certificate,  a new Certificate of like tenor and Percentage Interest but bearing a number
not  contemporaneously  outstanding.  Upon the issuance of any new  Certificate  under this  Section,  the
Securities  Administrator  may require the payment by the  Certificateholder  of a sum sufficient to cover
any tax or other governmental  charge that may be imposed in relation thereto.  Any duplicate  Certificate
issued pursuant to this Section shall constitute  complete and  indefeasible  evidence of ownership in the
Trust Fund, as if originally  issued,  whether or not the lost,  stolen or destroyed  Certificate shall be
found at any time.

Section 4.04.     Persons Deemed Owners.

                  Prior to due presentment of a Certificate for  registration of transfer,  the Depositor,
the  Trustee,  the  Certificate  Insurer  (with  respect to the Insured  Certificates  for the Term of the
Policy) the  Securities  Administrator,  the  Certificate  Registrar and any agent of the  Depositor,  the
Trustee,  the Certificate  Insurer,  the Securities  Administrator or the Certificate  Registrar may treat
the Person in whose name any  Certificate is registered as the owner of such  Certificate  for the purpose
of receiving  distributions  pursuant to Section 3.05 and for all other purposes  whatsoever,  and none of
the Depositor, the Trustee, the Securities  Administrator,  the Certificate Registrar nor any agent of the
Depositor,  the Trustee,  the Securities  Administrator or the Certificate  Registrar shall be affected by
notice to the contrary.

Section 4.05.      Exchangeable Certificates.

         (a)       Upon the presentation  and surrender by any Holder of its  Exchangeable  Certificates in
the  appropriate  combination as set forth on Schedule B, such Holder shall  hereunder  transfer,  assign,
set over and otherwise  convey to the  Securities  Administrator,  all of such Holder’s  right,  title and
interest in and to such  Exchangeable  Certificates,  including all payments of interest  thereon received
after the month of the exchange.

         The  Securities   Administrator   acknowledges   the  transfer  and  assignment  of  Exchangeable
Certificates  pursuant  to the  foregoing  paragraph,  and hereby  declares  that it will hold the same in
trust for the Certificateholders on the terms in this Agreement contained.

         (b)        Exchangeble  Certificates  shall  be  exchangeable  on the  books  of DTC for  Exchanged
Certificates,  and  Exchanged  Certificates  shall be  exchangeable  on the books of DTC for  Exchangeable
Certificates,  on and after the Closing Date and for the one-year  period  following  the Closing Date, by
notice  to the  Securities  Administrator  substantially  in the forms of  Exhibit G hereto  and under the
terms and conditions hereinafter set forth.

           In  the  case  of  each  Combination  Group,   Certificates  of  the  Classes  of  Exchangeable
Certificates in such  Combination  Group shall be exchangeable  for Certificates of the Class of Exchanged
Certificates  related  to such  Combination  Group in  respective  denominations  determined  based on the
proportion  that the initial  principal  amounts of such  Exchangeable  Certificates  bear to the original
notional  amounts  of the  related  Exchanged  Certificates,  as set  forth in  Schedule  B. Upon any such
exchange the portions of the Exchangeable  Certificates  designated for exchange shall be deemed cancelled
and  replaced  by the  Exchanged  Certificate  issued in  exchange  therefor.  Correspondingly,  Exchanged
Certificates  related to a Combination  Group may be further  designated for exchange for  Certificates of
the Exchangeable  Classes in such Combination  Group in respective  denominations  determined based on the
proportion  that the initial  principal  amounts of such  Exchangeable  Certificates  bear to the original
notional  amounts of the  related  Exchanged  Certificates,  as set forth in Schedule B. There shall be no
limitation  on the number of exchanges  authorized  pursuant to this  Section  4.05.  Certificates  may be
exchanged  pursuant to this  Section 4.05 for a period of one year from the Closing  Date,  after which no
exchanges  will be permitted to be made,  and,  except as provided in the following  paragraph,  no fee or
other  charge  shall  be  payable  to the  Trustee,  the  Securities  Administrator  or DTC in  connection
therewith.

         In  order to  effect  an  exchange  of  Certificates,  the  Certificateholder  shall  notify  the
Securities    Administrator    in    writing    or    by    e-mail    at    William.August@wellsfargo.com,
Michelle.Y.Treadwell@wellsfargo.com  and  GCTSSPGTEAMB-2@wellsfargo.com  no later than seven Business Days
before the proposed  exchange  date. The exchange date may be any Business Day from and including the 25th
day of the  month  to the  second  to the  last  Business  Day  of the  month  subject  to the  Securities
Administrator’s  approval.  The notice must be on the  Certificateholder’s  letterhead,  carry a medallion
stamp  guarantee  and set forth the following  information:  the CUSIP number of both  Certificates  to be
exchanged and Certificates to be received;  Current  Principal  Balance or Current Notional Amount and the
original   principal   balance  or   notional   amount  of  the   Certificates   to  be   exchanged;   the
Certificateholder’s  DTC participant  number;  and the proposed exchange date. After receiving the notice,
the Securities  Administrator shall e-mail the  Certificateholder  with wire payment instructions relating
to the exchange fee. The  Securities  Administrator  will notify the  Depositor of the proposed  exchange,
and the  Depositor  or an  affiliate of the  Depositor  will apply for the CUSIP number for the  Exchanged
Certificate  or  Certificates  to be issued.  The  Securities  Administrator  will utilize the Deposit and
Withdrawal  System at DTC to  exchange  the  certificates.  A notice  becomes  irrevocable  on the seventh
Business Day before the proposed exchange date.

         Notwithstanding  any other  provision  herein set forth, a fee shall be payable to the Securities
Administrator in connection with each exchange equal to $5,000.

         The Securities  Administrator  shall make the first  distribution on an Exchanged  Certificate or
an  Exchangeable  Certificate  received  in an  exchange  transaction  on  the  Distribution  Date  in the
following  month to the  Certificateholder  of record as of the close of  business  on the last day of the
month of the exchange.

or other  instruments  which are  specifically  required to be furnished to the Trustee or the  Securities
Administrator pursuant to any provision of this Agreement,  the Trustee and the Securities  Administrator,
respectively,  shall  examine them to determine  whether they are in the form  required by this  Agreement
and  the  Underlying  Agreements;   provided,  however,  that  neither  the  Trustee  nor  the  Securities
Administrator  shall  be  responsible  for  the  accuracy  or  content  of  any  resolution,  certificate,
statement,  opinion, report, document, order or other instrument furnished hereunder;  provided,  further,

that the  Trustee  or the  Securities  Administrator,  respectively,  after  so  requesting  of the  party
required to deliver the same,  does not  receive  satisfactorily  corrected  documents  or a  satisfactory
explanation regarding any such nonconformities.

(b)      No  provision  of this  Agreement  shall be  construed  to relieve the Trustee or the  Securities
Administrator  from liability for its own negligent  action,  its own negligent  failure to act or its own
willful misconduct; provided, however, that:

(i)      The duties and  obligations of the Trustee and the Securities  Administrator  shall be determined
         solely by the express  provisions  of this  Agreement,  neither  the  Trustee nor the  Securities
         Administrator  shall be  liable  except  for the  performance  of  their  respective  duties  and
         obligations  as  are  specifically  set  forth  in  this  Agreement,   no  implied  covenants  or
         obligations   shall  be  read  into  this  Agreement   against  the  Trustee  or  the  Securities
         Administrator  and,  in the  absence of bad faith on the part of the  Trustee  or the  Securities
         Administrator,  respectively,  the Trustee or the  Securities  Administrator,  respectively,  may
         conclusively  rely,  as to the  truth  of the  statements  and the  correctness  of the  opinions
         expressed  therein,  upon any certificates or opinions furnished to the Trustee or the Securities
         Administrator, respectively, and conforming to the requirements of this Agreement;

(ii)     Neither the Trustee nor the Securities  Administrator  shall be liable in its individual capacity
         for an error of judgment made in good faith by a Responsible  Officer or Responsible  Officers of
         the  Trustee or an  officer of the  Securities  Administrator,  respectively,  unless it shall be
         proved  that  the  Trustee  or the  Securities  Administrator,  respectively,  was  negligent  in
         ascertaining the pertinent facts;

(iii)    Neither the Trustee nor the Securities  Administrator  shall be liable with respect to any action
         taken,  suffered or omitted to be taken by it in good faith in  accordance  with the direction of
         the Certificate Insurer or the Majority  Certificateholders  in accordance with the terms of this
         Agreement,  as to the  time,  method  and  place of  conducting  any  proceeding  for any  remedy
         available to the Trustee or the Securities Administrator,  respectively,  or exercising any trust
         or other power conferred upon the Trustee or the Securities  Administrator,  respectively,  under
         this Agreement;

(iv)     The Securities  Administrator  shall not in any way be liable by reason of any  insufficiency  in
         any Account  held by or in the name of  Securities  Administrator  unless it is  determined  by a
         court of competent  jurisdiction that the Securities  Administrator’s gross negligence or willful
         misconduct  was  the  primary  cause  of  such  insufficiency  (except  to the  extent  that  the
         Securities Administrator is obligor and has defaulted thereon);

(v)      Anything in this  Agreement  to the  contrary  notwithstanding,  in no event shall the Trustee or
         the Securities  Administrator be liable for special,  indirect or consequential loss or damage of
         any kind  whatsoever  (including  but not  limited to lost  profits),  even if the Trustee or the
         Securities  Administrator,  respectively,  has been  advised  of the  likelihood  of such loss or
         damage and regardless of the form of action;

(vi)     None of the Securities  Administrator,  the Depositor or the Trustee shall be responsible for the
         acts or omissions of the other,  it being  understood  that this Agreement shall not be construed
         to render them partners, joint venturers or agents of one another;

(vii)    Neither  the  Trustee nor the  Securities  Administrator  shall be required to expend or risk its
         own  funds or  otherwise  incur  financial  liability  in the  performance  of any of its  duties
         hereunder,  or in the exercise of any of its rights or powers,  if there is reasonable ground for
         believing that the repayment of such funds or adequate  indemnity  against such risk or liability
         is not reasonably  assured to it;  provided that this  provision  shall not be deemed to abrogate
         the  responsibilities  undertaken  by the Trustee  hereunder  to perform  routine  administrative
         duties in accordance with the terms of this Agreement;

(viii)   Neither the Trustee nor the Securities  Administrator  shall be deemed to have notice of any fact
         or circumstance  upon the occurrence of which it may be required to take action  hereunder unless
         a Responsible  Officer of the Trustee or Securities  Administrator  has actual  knowledge of such
         event,  fact or  circumstance  or unless  written  notice of any such  event is  received  by the
         Trustee at its Corporate Trust Office;
(ix)     No  provision  in this  Agreement  shall  require  the Trustee to expend or risk its own funds or
         otherwise  incur any  personal  financial  liability in the  performance  of any of its duties as
         Trustee  hereunder,  or in the exercise of any of its rights or powers, if the Trustee shall have
         reasonable  grounds for  believing  that  repayment of funds or adequate  indemnity  against such
         risk or liability is not  reasonably  assured to it;  provided that this  provision  shall not be
         deemed to abrogate the  responsibilities  undertaken by the Trustee  hereunder to perform routine
         administrative duties in accordance with the terms hereof; and

(x)      Except for those  actions that the Trustee or the  Securities  Administrator  is required to take
         hereunder,  neither the Trustee nor the  Securities  Administrator  shall have any  obligation or
         liability  to take any action or to refrain  from taking any action  hereunder  in the absence of
         written direction as provided hereunder.

duplicate,  one  copy  of  which  instrument  shall  be  delivered  to each of the  resigning  Trustee  or

accepted  appointment  within 30 days  after the  giving of such  notice  of  resignation,  the  resigning
Trustee or Securities  Administrator may petition any court of competent  jurisdiction for the appointment
of a successor Trustee or Securities Administrator.

(b)      If at any time the  Trustee  or the  Securities  Administrator  shall  cease  to be  eligible  in
accordance  with the  provisions of Section 5.06 and shall fail to resign after written  request  therefor
by the  Depositor  or the  Majority  Certificateholders,  or if at any time the Trustee or the  Securities
Administrator  shall  become  incapable  of acting,  or shall be  adjudged a bankrupt or  insolvent,  or a

(c)      Majority  Certificateholders  may at any time remove the Trustee or the Securities  Administrator
and appoint a successor  Trustee or Securities  Administrator  by written  instrument or  instruments,  in
quadruplicate,  signed by such Holders or their  attorneys-in-fact  duly  authorized,  one complete set of
which  instruments  shall be delivered to the Depositor,  the Securities  Administrator (if the Trustee is
removed),  the  Trustee  (if  the  Securities   Administrator  is  removed),  the  Trustee  or  Securities
Administrator  so removed and the successor so  appointed.  A copy of such  instrument  shall be delivered
to the  Certificateholders by the Depositor.  All reasonable  out-of-pocket costs and expenses incurred in
connection  with such removal and replacement of the Trustee,  including  without  limitation,  reasonable
attorneys fees and expenses, shall be borne by the party requesting such action.

(d)      No  resignation or removal of the Trustee or the Securities  Administrator  and  appointment of a
successor  Trustee or  Securities  Administrator  pursuant to any of the  provisions of this Section shall
become effective  except upon  appointment of and acceptance of such appointment by the successor  trustee
as provided in Section  5.08 and (ii) no entity may be  appointed  as a  successor  Trustee or  Securities
Administrator if such  appointment  would result in a withdrawal or downgrading of any then current rating
assigned to the  Certificates by the Rating Agencies.  As long as the Policy is in effect,  the Trustee or
Securities  Administrator  will send a written notice,  as applicable,  to the Certificate  Insurer of any
such resignation, removal or appointment.

Section 5.08.     Successor Trustee and Successor Securities Administrator.

(a)      Any  successor  Trustee or Securities  Administrator  appointed as provided in Section 5.07 shall
execute,  acknowledge and deliver to the Depositor,  the Certificateholders and to its predecessor Trustee
or Securities  Administrator  an instrument  accepting  such  appointment  hereunder.  The  resignation or
removal of the  predecessor  Trustee or  Securities  Administrator  shall then become  effective  and such
successor Trustee or Securities Administrator,  without any further act, deed or conveyance,  shall become
fully vested with all the rights, powers, duties and obligations of its predecessor  hereunder,  with like
effect as if originally named as Trustee or Securities  Administrator  herein. The predecessor  Trustee or
Securities  Administrator  shall after payment of its outstanding  fees and expenses  promptly  deliver to
the successor  Trustee or  Securities  Administrator,  as  applicable,  the  Underlying  Certificates  and
related  documents and statements held by it hereunder,  and the Depositor and the predecessor  Trustee or
Securities  Administrator,  as applicable,  shall execute and deliver such  instruments  and do such other
things as may  reasonably  be  required  for more  fully  and  certainly  vesting  and  confirming  in the
successor  Trustee or  Securities  Administrator,  as  applicable,  all such  rights,  powers,  duties and
obligations.

(b)      No successor  Trustee or Securities  Administrator  shall accept  appointment as provided in this
Section unless at the time of such acceptance  such successor  Trustee or Securities  Administrator  shall
be eligible under the provisions of Section 5.06.

(c)      Upon  acceptance of appointment by a successor  Trustee or Securities  Administrator  as provided
in this Section,  the successor  Trustee or Securities  Administrator  shall mail notice of the succession
of such Trustee or Securities  Administrator  hereunder to all  Certificateholders  at their  addresses as
shown in the Certificate  Register,  the  Certificate  Insurer and to the Rating  Agencies.  The Depositor
shall cause such notice to be mailed at the expense of the Depositor.

(d)      Notwithstanding  anything in this Agreement or the Underlying  Agreements to the contrary, in the
event  that  the  paying  agent  for the  Underlying  Series  resigns  or is  terminated,  the  Securities
Administrator  (if it was  such  paying  agent)  shall  resign  as  Securities  Administrator  under  this
Agreement  and the Depositor  may appoint the  successor  paying agent as the successor to the  Securities
Administrator hereunder.

Section 5.09.     Merger or Consolidation of Trustee or Securities Administrator.

                  Any state bank or trust company or national  banking  association into which the Trustee
or the Securities  Administrator  may be merged or converted or with which it may be  consolidated  or any
state bank or trust  company or national  banking  association  resulting  from any merger,  conversion or
consolidation  to which the Trustee or the Securities  Administrator,  respectively,  shall be a party, or
any state bank or trust company or national banking  association  succeeding to all or  substantially  all
of the corporate  trust business of the Trustee or the Securities  Administrator,  respectively,  shall be
the  successor of the Trustee or the  Securities  Administrator,  respectively,  hereunder,  provided such
state bank or trust company or national  banking  association  shall be eligible  under the  provisions of
Section 5.06. Such  succession  shall be valid without the execution or filing of any paper or any further
act on the part of any of the  parties  hereto,  anything  herein  to the  contrary  notwithstanding.  The
Trustee or the  Securities  Administrator  shall mail  notice of any such merger or  consolidation  to the
Depositor,  the  Certificate  Insurer  and to the  Certificateholders  at  their  address  as shown in the
Certificate Register.

Section 5.10.     Appointment of Co-Trustee or Separate Trustee.

(a)      Notwithstanding  any other provisions  hereof,  at any time, for the purpose of meeting any legal
requirements of any  jurisdiction in which any part of the Trust or property  constituting the same may at
the time be located,  the Depositor and the Trustee  acting jointly shall have the power and shall execute
and deliver all  instruments  to appoint one or more Persons  approved by the Trustee and the Depositor to
act as co-trustee or co-trustees,  jointly with the Trustee, or separate trustee or separate trustees,  of
all or any part of the Trust, and to vest in such Person or Persons,  in such capacity,  such title to the
Trust,  or any part thereof,  and,  subject to the other  provisions  of this Section  5.10,  such powers,
duties,  obligations,  rights and trusts as the  Depositor  and the  Trustee  may  consider  necessary  or
desirable.  No  co-trustee  or  separate  trustee  hereunder  shall  be  required  to meet  the  terms  of
eligibility  as a successor  trustee under Section 5.06  hereunder;  provided,  that if the  co-trustee or
separate  trustee  does not meet such  eligibility  standards,  the Trustee  shall  remain  liable for its
actions  hereunder,  and no notice to  Certificateholders  of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 5.08 hereof.

(b)      If the Depositor  shall not have joined in such  appointment  within 15 days after the receipt by
it of a written  request so to do, the Trustee shall have the power to make such  appointment  without the
Depositor.

(c)      In the case of any  appointment  of a  co-trustee  or separate  trustee  pursuant to this Section
5.10, all rights,  powers,  duties and  obligations  conferred or imposed upon the Trustee and required to
be conferred on such co-trustee  shall be conferred or imposed upon and exercised or performed  jointly by
the Trustee and such separate  trustee or co-trustee  jointly,  except to the extent that under any law of
any  jurisdiction  in which any particular act or acts are to be performed  (whether as Trustee  hereunder
or as successor to the Master  Servicer  hereunder),  the Trustee shall be  incompetent  or unqualified to
perform such act or acts,  in which event such  rights,  powers,  duties and  obligations  (including  the
holding of title to the Trust Fund or any portion  thereof in any such  jurisdiction)  shall be  exercised
and performed by such separate trustee or co-trustee at the direction of the Trustee.

(d)      Any notice,  request or other  writing given to the Trustee shall be deemed to have been given to
each of the then separate  trustees and  co-trustees,  as effectively  as if given to each of them.  Every
instrument  appointing  any  separate  trustee  or  co-trustee  shall  refer  to  this  Agreement  and the
conditions  of this Article V. Each separate  trustee and  co-trustee,  upon its  acceptance of the trusts
conferred,  shall be vested with the estates or  property  specified  in its  instrument  of  appointment,
either jointly with the Trustee or separately,  as may be provided therein,  subject to all the provisions
of this Agreement,  specifically  including every provision of this Agreement  relating to the conduct of,
affecting  the liability  of, or affording  protection  to, the Trustee.  Every such  instrument  shall be
filed with the Trustee.

(e)      To the extent not  prohibited  by law,  any  separate  trustee or  co-trustee  may,  at any time,
request the Trustee,  its agent or attorney-in-fact,  with full power and authority,  to do any lawful act
under or with  respect  to this  Agreement  on its  behalf  and in its name.  If any  separate  trustee or
co-trustee shall die, become incapable of acting,  resign or be removed,  all of its estates,  properties,
rights,  remedies and trusts shall vest in and be  exercised  by the Trustee,  to the extent  permitted by
law, without the appointment of a new or successor Trustee.

(f)      No trustee under this  Agreement  shall be personally  liable by reason of any act or omission of
another  trustee  under this  Agreement.  The  Depositor  and the Trustee  acting  jointly may at any time
accept the resignation of or remove any separate trustee or co-trustee.

                                              THE DEPOSITOR

Section 6.01.     Liability of the Depositor.

                  The  Depositor  shall  be  liable  in  accordance  herewith  only to the  extent  of the
respective obligations specifically imposed upon and undertaken by the Depositor herein.

Section 6.02.     Merger, Consolidation or Conversion of the Depositor.

                  Subject  to the  following  paragraph,  the  Depositor  will  keep  in full  effect  its
existence,   rights  and  franchises  as  a  corporation  under  the  laws  of  the  jurisdiction  of  its
incorporation,  and will obtain and preserve its qualification to do business as a foreign  corporation in
each  jurisdiction  in which such  qualification  is or shall be  necessary  to protect the  validity  and
enforceability of this Agreement and the Certificates and to perform its duties under this Agreement.

                  The Depositor  may be merged or  consolidated  with or into any Person,  or transfer all
or  substantially  all of its assets to any Person,  in which case any Person resulting from any merger or
consolidation  to which the Depositor  shall be a party,  or any Person  succeeding to the business of the
Depositor,  shall be the  successor of the  Depositor  hereunder,  without the  execution or filing of any
paper or any  further  act on the part of any of the  parties  hereto,  anything  herein  to the  contrary
notwithstanding.

Section 6.03.     Limitation on Liability of the Depositor and Others.

                  Neither the Depositor  nor any of the  directors,  officers,  employees or agents of the
Depositor  shall be under any liability to the Trust Fund or the  Certificateholders  for any action taken
or for refraining  from the taking of any action in good faith pursuant to this  Agreement,  or for errors
in judgment;  provided,  however,  that this  provision  shall not protect the Depositor or any such other
Person  against  any breach of a  representation  or  warranty  made  herein,  or against  any  expense or
liability  specifically  required  to be borne  thereby  pursuant  to the terms  hereof,  or  against  any
liability  which would otherwise be imposed by reason of willful  misfeasance,  bad faith or negligence in
the  performance  of  obligations  or  duties  hereunder,  or by  reason  of  reckless  disregard  of such
obligations and duties.  The Depositor and any director,  officer,  employee or agent of the Depositor may
rely in good faith on any document of any kind which,  prima facie, is properly  executed and submitted by
any Person  respecting  any matters  arising  hereunder.  Provided  that such action is not related to its
representations  made in or its  duties  under  this  Agreement,  the  Depositor  shall  not be under  any
obligation to appear in,  prosecute or defend any action or  proceeding  unless such action in its opinion
does not involve it in any expense or liability.

                                               ARTICLE VII

                                               TERMINATION

Section 7.01.    Termination.

(a)      The respective  obligations and responsibilities of the Depositor,  the Securities  Administrator
and the Trustee  created  hereby with  respect to the  Certificates  (other  than the  obligation  to make
certain  payments,  any  obligations  under  Section 5.05 and the  obligation  to send certain  notices to
Certificateholders  as  hereinafter  set forth)  shall  terminate  upon the later of (i) the making of the
final  payment  on  or  other  liquidation  of  the  Underlying  Certificates  and  (ii)  the  payment  to
Certificateholders  and the  Certificate  Insurer of all amounts  required to be paid to them  pursuant to
this  Agreement;  provided,  however,  that in no event shall the trust created hereby continue beyond the
expiration  of  twenty-one  years  from the death of the last  survivor  of the  descendants  of Joseph P.
Kennedy,  the late  ambassador  of the  United  States  to the  Court of St.  James’s,  living on the date
hereof.

(b)      The  Securities  Administrator  shall,  in accordance  with Section 7.05,  give a Notice of Final
Distribution to the Holders,  the Depositor,  the Trustee, the Certificate Insurer and the Rating Agencies
as soon as practicable of the  Distribution  Date on which the Securities  Administrator  anticipates that
the final distribution will be made on the Certificates, which notice shall:

(i)      specify  the  Distribution  Date on which the final  distribution  is  anticipated  to be made to
         Holders;

(ii)     specify the amount of any such final distribution, if known; and

(iii)    state  that the  final  distribution  to the  Holders  will be made  only  upon  presentment  and
         surrender of their Certificates at the office of the Securities Administrator therein specified.

If the payment on the Certificates is not made on the anticipated  Distribution  Date for any reason,  the
Securities  Administrator  shall promptly mail notice thereof to each Holder, the Depositor,  the Trustee,
the Certificate Insurer and to the Rating Agencies.

(c)      Upon  presentment and surrender of Certificates by the Holders of such  Certificates on the Final
Distribution Date, the Securities  Administrator shall distribute to such  Certificateholders  the amounts
otherwise  distributable  to them on such  Distribution  Date pursuant to Section  3.05(a).  Any funds not
distributed  on a Final  Distribution  Date  because of the  failure of any  Certificateholders  to tender
their Certificates  shall be set aside and held in trust for the account of the appropriate  non-tendering
Certificateholders,  and the Trust Fund shall  terminate.  If any Certificates as to which Notice of Final
Distribution  has  been  given  pursuant  to this  Section  7.01  shall  not  have  been  surrendered  for
cancellation  within six months  after the time  specified in such notice,  the  Securities  Administrator
shall mail a second  notice to the  remaining  Certificateholders,  at their last  addresses  shown in the
Certificate  Register,  to surrender their  Certificates for  cancellation in order to receive,  from such
funds held, the final  distribution  with respect thereto.  If within one year after the second notice any
Certificate  shall  not have  been  surrendered  for  cancellation,  the  Securities  Administrator  shall
directly  or  through  an  agent,  take  reasonable  steps to  contact  the  remaining  Certificateholders
concerning  surrender  of their  Certificates.  The costs and  expenses of  maintaining  such funds and of
contacting  Certificateholders  shall be paid out of the assets  which  remain  held.  If within two years
after  the  second  notice  any  Certificates  shall  not have  been  surrendered  for  cancellation,  the
Securities  Administrator  shall  segregate  all amounts  distributable  to the Holders  thereof and shall
thereafter  hold such amounts for the benefit of such Holders.  No interest  shall accrue or be payable to
any  Certificateholder  on any amount held as a result of such  Certificateholder’s  failure to  surrender
its Certificate(s) for final payment thereof in accordance with this Section 7.01.

                                               ARTICLE VIII

                                         MISCELLANEOUS PROVISIONS

Section 8.01.    Amendment.

(a)      This  Agreement may be amended from time to time by the Depositor,  the Securities  Administrator
and the Trustee,  without the prior  consent of any  Certificateholder  and, with respect to any amendment
that  adversely  affects  the  interests  of  any of  the  Holders  of  the  Insured  Certificates  or the
Certificate Insurer, with the prior written consent of the Certificate Insurer:

(i)      to cure any ambiguity;

(ii)     to  correct  or  supplement  any  provisions  herein,  which may be  inconsistent  with any other
         provisions herein;

         which shall not be materially inconsistent with the existing provisions of this Agreement;

(iv)     to make such  modifications  as may be  permitted  or required  hereunder  in  connection  with a
         repurchase of the Underlying Certificates pursuant to Section 2.03(c) hereof; and

(v)      to revise or correct any  provisions to reflect the  obligations of the parties to this Agreement
         as they relate to Regulation AB;

provided  that with  respect to clause  (iv),  such  amendment  shall not, as  evidenced  by an Opinion of
Counsel  delivered  to the Trustee or a letter  from each Rating  Agency  confirming  that such  amendment
shall not result in a downgrade or withdrawal of a rating on any of the  Certificates  (in each case,  the
expense  of which  shall be paid for by the  Depositor),  adversely  affect in any  material  respect  the
interests of any Certificateholder.

(b)      This  Agreement  may  also  be  amended  from  time  to time  by the  Depositor,  the  Securities
Administrator  and the Trustee with the prior written consent of the Majority  Certificateholders  (or, to
the extent any such amendment  only effects a particular  Class of  Certificates,  the holders of at least
50% of the aggregate  Current  Principal  Amount or Current Notional Amount of Certificates of such Class)
for the  purpose  of  adding  any  provisions  to or  changing  in any  manner or  eliminating  any of the
provisions  of this  Agreement  or of  modifying  in any  manner  the  rights  of the  Certificateholders;
provided, however, that no such amendment shall:

(i)      reduce in any manner the amount of, or delay the timing of,  payments  which are  required  to be
         distributed on any Certificate without the consent of the Holder of such Certificate; or

(ii)     modify  the  provisions  of  this  Section  8.01  without  the  consent  of  the  Holders  of all
         Certificates.

(c)      Promptly  after the execution of any such amendment the  Securities  Administrator  shall furnish
written  notification  of the  substance  of such  amendment  to each  Certificateholder.  It shall not be
necessary for the consent of  Certificateholders  under this Section 7.01 to approve the  particular  form
of any  proposed  amendment,  but it shall be  sufficient  if such  consent  shall  approve the  substance
thereof.  The manner of obtaining  such  consents and of  evidencing  the  authorization  of the execution
thereof  by  Certificateholders  shall  be  subject  to  such  reasonable  regulations  as the  Securities
Administrator  may  prescribe.  The Securities  Administrator  shall also provide a copy of such amendment
or notice to the Rating Agencies and the Certificate Insurer.

(d)      Prior to the  execution  of any  amendment  to this  Agreement,  the Trustee  and the  Securities
Administrator  shall be entitled to receive and rely upon an Opinion of Counsel  addressed  to the Trustee
and the  Securities  Administrator  stating that (i) the  execution of such  amendment  is  authorized  or
permitted  by this  Agreement  and (ii) will not result in the  imposition  of a tax on the Trust or cause
the Trust to fail to be  classified  as a grantor trust under subpart E, part I of subchapter J of chapter
1 of the Code.  The Trustee and the  Securities  Administrator  may, but shall not be obligated  to, enter
into any such  amendment  which affects the Trustee’s or the  Securities  Administrator’s  own  respective
rights, duties or immunities under this Agreement.

                  This Agreement may be executed  simultaneously  in any number of  counterparts,  each of
which counterparts  shall be deemed to be an original,  and such counterparts shall constitute but one and
the same instrument.

Section 8.03.     Limitation on Rights of Certificateholders.

(a)      The death or incapacity of any  Certificateholder  shall not operate to terminate  this Agreement
or the Trust  Fund,  nor  entitle  such  Certificateholder’s  legal  representatives  or heirs to claim an
accounting  or to take any action or  proceeding  in any court for a partition  or winding up of the Trust
Fund, nor otherwise affect the rights, obligations and liabilities of the parties hereto or any of them.

(b)      No  Certificateholder  shall have any right to vote (except as expressly  provided for herein) or
in any manner  otherwise  control the operation and  management of the Trust Fund, or the  obligations  of
the parties hereto,  nor shall anything  herein set forth, or contained in the terms of the  Certificates,
be construed so as to  constitute  the  Certificateholders  from time to time as partners or members of an
association;  nor shall any  Certificateholder  be under any liability to any third party by reason of any
action taken by the parties to this Agreement pursuant to any provision hereof.

(c)      No  Certificateholder  shall  have any right by  virtue of any  provision  of this  Agreement  to
institute  any suit,  action or  proceeding  in  equity  or at law upon or under or with  respect  to this
Agreement,  unless such  Holder  previously  shall have given to the  Trustee and the  Depositor a written
notice of default hereunder,  and of the continuance  thereof, as hereinbefore  provided,  and unless also
the  Majority  Certificateholders  shall have made  written  request  upon the Trustee to  institute  such
action,  suit or  proceeding  in its own name as Trustee  hereunder  and shall have offered to the Trustee
such  reasonable  indemnity as it may require  against the costs,  expenses and liabilities to be incurred
therein or thereby,  and the Trustee,  for 30 days after its receipt of such notice,  request and offer of
indemnity,  shall have  neglected or refused to institute  any such action,  suit or  proceeding.  For the
prosecution  and  enforcement of the rights granted under this Section,  each and every  Certificateholder
and the Trustee shall be entitled to such relief as can be given either at law or in equity.

(d)      Unless a Certificate  Insurer  Default occurs and is  continuing,  the  Certificate  Insurer will
have the  right to  exercise  all  rights,  including  voting  rights,  which the  Certificateholders  of the Insured Certificates are
entitled  to  exercise  under  this  Agreement  and the other  Transaction  Documents.  In  addition,  the
Certificate  Insurer shall have the right to participate  in, to direct the enforcement or defense of, and
at the Certificate  Insurer’s sole option,  to institute or assume the defense of, any action,  proceeding
or  investigation  for any remedy available to the Trustee with respect to any matter that could adversely
affect the Trust or the Trust  Estate  relating to the  Insured  Certificates  or the  related  Underlying
Certificates,  or the rights or  obligations  of the  Certificate  Insurer,  under this  Agreement and the
other Transaction  Documents,  including (without  limitation) any insolvency or bankruptcy  proceeding in
respect of the  Depositor  or any  affiliate  thereof.  Following  written  notice to the  Trustee and the
Securities  Administrator,  the Certificate  Insurer shall have the exclusive  right to determine,  in its
sole discretion,  the actions  necessary to preserve and protect the Trust or the Trust Estate relating to
the  Insured  Certificates  or the related  Underlying  Certificates.  The  Certificate  Insurer  shall be
entitled to reimbursement by the Trust for all costs and expenses  incurred in connection with such action,  proceeding
or  investigation,  including  (without  limitation)  reasonable  attorney’s  fees  and  any  judgment  or
settlement entered into affecting the Certificate Insurer or the Certificate Insurer’s interests.

(e)      The  Certificate  Insurer is an intended  third-party  beneficiary of this Agreement with respect
to the rights of the Classes of Insured  Certificates.  Any right  conferred  to the  Certificate  Insurer
shall be suspended  after the occurrence and during the  continuation  of a Certificate  Insurer  Default.
During any period of suspension,  the Certificate  Insurer's rights hereunder shall vest in the Holders of
the Insured  Certificates (to the extent such Holders otherwise has such rights  hereunder).  At such time
as the Current  Principal Amount of the Insured  Certificates has been reduced to zero and the Certificate
Insurer has been  reimbursed for all amounts to which it is entitled  hereunder  pursuant to Section 3.05,
the Certificate Insurer's rights hereunder shall terminate.

Section 8.04.     Governing Law.

                  This Agreement and the  Certificates  shall be construed in accordance  with the laws of
the State of New York applicable to agreements  made and to be performed in said state (without  reference

(e)      In determining  whether the Holders of the requisite  Percentage  Interest of  Certificates  have
given any request, demand,  authorization,  direction,  notice, consent or waiver hereunder,  Certificates

protected in relying upon any such request, demand,  authorization,  direction, notice, consent or waiver,
only Certificates which the Trustee or the Securities Administrator,  as applicable,  knows to be so owned
shall  be so  disregarded.  Certificates  which  have  been  pledged  in good  faith to the  Trustee,  the
Securities  Administrator or the Depositor or any Affiliate  thereof may be regarded as outstanding if the
pledgor  establishes  to the  satisfaction  of the Trustee or the Securities  Administrator  the pledgor’s
right to act with  respect to such  Certificates  and that the pledgor is not an Affiliate of the Trustee,
the Securities Administrator or the Depositor, as the case may be.

caused their names to be signed hereto by their  respective  duly authorized  officers,  all as of the day

                                              SERIES 2006-R1

         evidencing a Percentage Interest in the distributions allocable to the Class A-[  ]
         Certificates with respect to a Trust Fund consisting primarily of the Underlying
         Certificates sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

                  This  Certificate  is payable  solely  from the assets of the Trust  Fund,  and does not
represent an obligation of or interest in Structured  Asset  Mortgage  Investments II Inc., the Securities
Administrator  or the Trustee  referred to below or any of their  affiliates or any other person.  Neither
this  Certificate nor the related  Underlying  Certificate  are guaranteed or insured by any  governmental
entity or by Structured  Asset Mortgage  Investments II Inc., the Securities  Administrator or the Trustee
or any of their affiliates or any other person other than with respect to the Insured  Certificates  which
are Insured by the  Certificate  Insurer.  None of Structured  Asset  Mortgage  Investments  II Inc.,  the
Securities  Administrator,  the Trustee or any of their  affiliates  will have any obligation with respect
to any certificate or other obligation secured by or payable from payments on the Certificates.

                  This  certifies  that  Cede & Co. is the  registered  owner of the  Percentage  Interest
evidenced  hereby  in the  beneficial  ownership  interest  of  Certificates  of the  same  Class  as this
Certificate  in a trust (the “Trust Fund”)  primarily  consisting of the Underlying  Certificates  sold by
Structured  Asset Mortgage  Investments II Inc.  (“SAMI II”).  The  Underlying  Certificates  were sold by
Bear,  Stearns & Co.  Inc.  to SAMI II. The Trust Fund was  created  pursuant  to the  Pooling  Agreement,
dated as of the Closing Date,  (the  “Agreement”),  among SAMI II, as depositor (the  “Depositor”),  Wells
Fargo, as securities  administrator  (the “Securities  Administrator”)  and JPMorgan Chase Bank,  National
Association as trustee (the “Trustee”),  a summary of certain of the pertinent  provisions of which is set
forth hereafter.  To the extent not defined herein,  capitalized  terms used herein shall have the meaning
ascribed  to them in the  Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions and conditions of the Agreement,  to which  Agreement the Holder of this  Certificate by virtue
of its acceptance hereof assents and by which such Holder is bound.

                  Interest on this  Certificate  will accrue  during the month prior to the month in which
a  Distribution  Date (as  hereinafter  defined)  occurs on the Current  Principal  Amount hereof at a per
annum rate equal to the  Pass-Through  Rate as described in the Agreement.  The  Securities  Administrator
will  distribute  on the  25th  day of each  month,  or,  if such  25th  day is not a  Business  Day,  the
immediately  following  Business Day (each, a “Distribution  Date”),  commencing on the First Distribution
Date  specified  above,  to the  Person  in whose  name this  Certificate  is  registered  at the close of
business on the last Business Day of the calendar  month  preceding the month of such  Distribution  Date,
an amount equal to the product of Percentage  Interest  evidenced by this  Certificate  and the amount (of
interest and  principal,  if any) required to be distributed  to the Holders of  Certificates  of the same
Class as this Certificate.

                  Distributions  on this  Certificate  will be made  by the  Securities  Administrator  by
check mailed to the address of the Person  entitled  thereto as such name and address  shall appear on the
Certificate  Register or, if such Person so requests by notifying the Securities  Administrator in writing
as specified in the Agreement by wire  transfer.  Notwithstanding  the above,  the final  distribution  on
this  Certificate  will be made after due notice by the Securities  Administrator  of the pendency of such
distribution  and only  upon  presentation  and  surrender  of this  Certificate  at the  office or agency
appointed by the  Securities  Administrator  for that purpose and  designated in such notice.  The Initial
Current  Principal  Amount of this  Certificate is set forth above.  The Current  Principal  Amount hereof
will be reduced to the extent of  distributions  allocable  to principal  hereon and any  Realized  Losses
allocable hereto.

                  This  Certificate is one of a duly authorized  issue of  Certificates  designated as set
forth on the face hereof (the  “Certificates”).  The Certificates,  in the aggregate,  evidence the entire
beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

                  The Certificateholder,  by its acceptance of this Certificate,  agrees that it will look
solely  to the  Trust  Fund  for  payment  hereunder  and  that  none  of the  Depositor,  the  Securities
Administrator  or the  Trustee  are liable to the  Certificateholders  for any amount  payable  under this
Certificate or the Agreement or, except as expressly  provided in the Agreement,  subject to any liability
under the Agreement.

                  This  Certificate  does not purport to summarize  the Agreement and reference is made to
the Agreement for the  interests,  rights and  limitations  of rights,  benefits,  obligations  and duties
evidenced hereby, and the rights, duties and immunities of the Securities Administrator and the Trustee.

                  The Agreement permits,  with certain exceptions therein provided,  the amendment thereof
and the  modification of the rights and  obligations of the Depositor,  the Securities  Administrator  and
the  Trustee  and the  rights  of the  Certificateholders  under  the  Agreement  from time to time by the
parties  thereto  with the  consent  of the  Holders  of  Certificates,  evidencing  Percentage  Interests
aggregating  not less  than 51% of the  Trust  Fund (or in  certain  cases,  Holders  of  Certificates  of
affected  Classes  evidencing such percentage of the Percentage  Interests  thereof).  Any such consent by
the  Holder of this  Certificate  shall be  conclusive  and  binding  on such  Holder  and upon all future
Holders of this  Certificate  and of any  Certificate  issued upon the  transfer  hereof or in lieu hereof
whether or not  notation of such consent is made upon this  Certificate.  The  Agreement  also permits the
amendment  thereof,  in certain  limited  circumstances,  without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain  limitations  therein set forth, the
transfer of this  Certificate  is  registrable  with the  Certificate  Registrar  upon  surrender  of this
Certificate  for  registration  of  transfer  at the  offices or  agencies  maintained  by the  Securities
Administrator for such purposes,  duly endorsed by, or accompanied by a written  instrument of transfer in
form  satisfactory  to the  Securities  Administrator  duly executed by the Holder hereof or such Holder’s
attorney  duly  authorized  in  writing,  and  thereupon  one  or  more  new  Certificates  in  authorized
denominations  representing  a like  aggregate  Percentage  Interest  will  be  issued  to the  designated
transferee.

                  The  Certificates  are issuable only as registered  Certificates  without coupons in the
Classes  and  denominations  specified  in the  Agreement.  As provided  in the  Agreement  and subject to
certain  limitations  therein set forth, this Certificate is exchangeable for one or more new Certificates
evidencing  the same Class and in the same  aggregate  Percentage  Interest,  as  requested  by the Holder
surrendering the same.

                  No service charge will be made to the  Certificateholders  for any such  registration of
transfer,  but the Securities  Administrator  may require  payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith.  The Depositor,  the Securities  Administrator,
the  Trustee  and any  agent of any of them may  treat  the  Person  in whose  name  this  Certificate  is
registered  as  the  owner  hereof  for  all  purposes,   and  none  of  the  Depositor,   the  Securities
Administrator, the Trustee or any such agent shall be affected by notice to the contrary.

                  [For Exchangeable Certificates] [As  provided in the  Agreement  and subject to certain  limitations  therein set forth,
this  Certificate  is  exchangeable  for  a  proportionate  interest  in  an  Exchanged  Certificate  in a
Combination  Group.  In  connection  with  each  such  exchange,  the  Certificateholder   shall  pay  the
Securities  Administrator a fee equal to $5,000 for such exchange  request.  The Securities  Administrator
shall make the first  distribution on a Certificate in such exchange  transaction on the Distribution Date
in the following month to the  Certificateholder  of record as of the close of business on the last day of
the month of the exchange.]

                  [For Exchanged Certificates]  [As provided in the Agreement and subect to certain limitations
therein set forth, this Certificate is exchangeable for a proportionate interest in one or more Exchangeable
Certificates in a Combination Group.  In connection with each such exchange, the Certificateholder shall pay
the Securities Administrator a fee equal to $5,000 for such exchange request.

                  The  obligations  created by the  Agreement  and the Trust Fund created  thereby  (other
than the  obligations  to make  payments to  Certificateholders  with  respect to the  termination  of the
Agreement)  shall  terminate  upon  the  earlier  of (i) the  making  of the  final  payment  on or  other
liquidation  of the  Underlying  Certificate,  or (ii) the  payment to  Certificateholders  of all amounts
required to be paid to them pursuant to the Agreement.  In no event,  however, will the Trust Fund created
by the  Agreement  continue  beyond  the  expiration  of 21  years  after  the  death of  certain  persons
identified in the Agreement.

                  Unless  this  Certificate  has been  countersigned  by an  authorized  signatory  of the
Securities  Administrator  by manual  signature,  this  Certificate  shall not be  entitled to any benefit
under the Agreement, or be valid for any purpose.

                  IN WITNESS  WHEREOF,  the  Securities  Administrator  has caused this  Certificate to be
duly executed.

         evidencing a Percentage Interest in the distributions allocable to the Class X-[  ]
         Certificates with respect to a Trust Fund consisting primarily of the Underlying
         Certificates sold by STRUCTURED ASSET MORTGAGE INVESTMENTS II INC.

                  This  Certificate  is payable  solely  from the assets of the Trust  Fund,  and does not
represent an obligation of or interest in Structured  Asset  Mortgage  Investments II Inc., the Securities
Administrator  or the Trustee  referred to below or any of their  affiliates or any other person.  Neither
this  Certificate nor the related  Underlying  Certificate  are guaranteed or insured by any  governmental
entity or by Structured  Asset Mortgage  Investments II Inc., the Securities  Administrator or the Trustee
or any of their affiliates or any other person other than with respect to the Insured  Certificates  which
are Insured by the  Certificate  Insurer.  None of Structured  Asset  Mortgage  Investments  II Inc.,  the
Securities  Administrator,  the Trustee or any of their  affiliates  will have any obligation with respect
to any certificate or other obligation secured by or payable from payments on the Certificates.

                  This  certifies  that  Cede & Co. is the  registered  owner of the  Percentage  Interest
evidenced  hereby  in the  beneficial  ownership  interest  of  Certificates  of the  same  Class  as this
Certificate  in a trust (the “Trust Fund”)  primarily  consisting of the Underlying  Certificates  sold by
Structured  Asset Mortgage  Investments II Inc.  (“SAMI II”).  The  Underlying  Certificates  were sold by
Bear,  Stearns & Co.  Inc.  to SAMI II. The Trust Fund was  created  pursuant  to the  Pooling  Agreement,
dated as of the Closing Date,  (the  “Agreement”),  among SAMI II, as depositor (the  “Depositor”),  Wells
Fargo, as securities  administrator  (the “Securities  Administrator”)  and JPMorgan Chase Bank,  National
Association as trustee (the “Trustee”),  a summary of certain of the pertinent  provisions of which is set
forth hereafter.  To the extent not defined herein,  capitalized  terms used herein shall have the meaning
ascribed  to them in the  Agreement.  This  Certificate  is issued  under  and is  subject  to the  terms,
provisions and conditions of the Agreement,  to which  Agreement the Holder of this  Certificate by virtue
of its acceptance hereof assents and by which such Holder is bound.

                  Interest on this  Certificate  will accrue  during the month prior to the month in which
a  Distribution  Date (as  hereinafter  defined)  occurs on the Current  Principal  Amount hereof at a per
annum rate equal to the  Pass-Through  Rate as described in the Agreement.  The  Securities  Administrator
will  distribute  on the  25th  day of each  month,  or,  if such  25th  day is not a  Business  Day,  the
immediately  following  Business Day (each, a “Distribution  Date”),  commencing on the First Distribution
Date  specified  above,  to the  Person  in whose  name this  Certificate  is  registered  at the close of
business on the last Business Day of the calendar  month  preceding the month of such  Distribution  Date,
an amount equal to the product of Percentage  Interest  evidenced by this  Certificate  and the amount (of
interest and  principal,  if any) required to be distributed  to the Holders of  Certificates  of the same
Class as this Certificate.

                  Distributions  on this  Certificate  will be made  by the  Securities  Administrator  by
check mailed to the address of the Person  entitled  thereto as such name and address  shall appear on the
Certificate  Register or, if such Person so requests by notifying the Securities  Administrator in writing
as specified in the Agreement by wire  transfer.  Notwithstanding  the above,  the final  distribution  on
this  Certificate  will be made after due notice by the Securities  Administrator  of the pendency of such
distribution  and only  upon  presentation  and  surrender  of this  Certificate  at the  office or agency
appointed by the  Securities  Administrator  for that purpose and  designated in such notice.  The Initial
Current  Principal  Amount of this  Certificate is set forth above.  The Current  Principal  Amount hereof
will be reduced to the extent of  distributions  allocable  to principal  hereon and any  Realized  Losses
allocable hereto.

                  This  Certificate is one of a duly authorized  issue of  Certificates  designated as set
forth on the face hereof (the  “Certificates”).  The Certificates,  in the aggregate,  evidence the entire
beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

                  The Certificateholder,  by its acceptance of this Certificate,  agrees that it will look
solely  to the  Trust  Fund  for  payment  hereunder  and  that  none  of the  Depositor,  the  Securities
Administrator  or the  Trustee  are liable to the  Certificateholders  for any amount  payable  under this
Certificate or the Agreement or, except as expressly  provided in the Agreement,  subject to any liability
under the Agreement.

                  This  Certificate  does not purport to summarize  the Agreement and reference is made to
the Agreement for the  interests,  rights and  limitations  of rights,  benefits,  obligations  and duties
evidenced hereby, and the rights, duties and immunities of the Securities Administrator and the Trustee.

                  The Agreement permits,  with certain exceptions therein provided,  the amendment thereof
and the  modification of the rights and  obligations of the Depositor,  the Securities  Administrator  and
the  Trustee  and the  rights  of the  Certificateholders  under  the  Agreement  from time to time by the
parties  thereto  with the  consent  of the  Holders  of  Certificates,  evidencing  Percentage  Interests
aggregating  not less  than 51% of the  Trust  Fund (or in  certain  cases,  Holders  of  Certificates  of
affected  Classes  evidencing such percentage of the Percentage  Interests  thereof).  Any such consent by
the  Holder of this  Certificate  shall be  conclusive  and  binding  on such  Holder  and upon all future
Holders of this  Certificate  and of any  Certificate  issued upon the  transfer  hereof or in lieu hereof
whether or not  notation of such consent is made upon this  Certificate.  The  Agreement  also permits the
amendment  thereof,  in certain  limited  circumstances,  without the consent of the Holders of any of the
Certificates.

                  As provided in the Agreement and subject to certain  limitations  therein set forth, the
transfer of this  Certificate  is  registrable  with the  Certificate  Registrar  upon  surrender  of this
Certificate  for  registration  of  transfer  at the  offices or  agencies  maintained  by the  Securities
Administrator for such purposes,  duly endorsed by, or accompanied by a written  instrument of transfer in
form  satisfactory  to the  Securities  Administrator  duly executed by the Holder hereof or such Holder’s
attorney  duly  authorized  in  writing,  and  thereupon  one  or  more  new  Certificates  in  authorized
denominations  representing  a like  aggregate  Percentage  Interest  will  be  issued  to the  designated
transferee.

                  The  Certificates  are issuable only as registered  Certificates  without coupons in the
Classes  and  denominations  specified  in the  Agreement.  As provided  in the  Agreement  and subject to
certain  limitations  therein set forth, this Certificate is exchangeable for one or more new Certificates
evidencing  the same Class and in the same  aggregate  Percentage  Interest,  as  requested  by the Holder
surrendering the same.

                  No service charge will be made to the  Certificateholders  for any such  registration of
transfer,  but the Securities  Administrator  may require  payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith.  The Depositor,  the Securities  Administrator,
the  Trustee  and any  agent of any of them may  treat  the  Person  in whose  name  this  Certificate  is
registered  as  the  owner  hereof  for  all  purposes,   and  none  of  the  Depositor,   the  Securities
Administrator, the Trustee or any such agent shall be affected by notice to the contrary.

                  [For Exchangeable Certificates] [As  provided in the  Agreement  and subject to certain  limitations  therein set forth,
this  Certificate  is  exchangeable  for  a  proportionate  interest  in  an  Exchanged  Certificate  in a
Combination  Group.  In  connection  with  each  such  exchange,  the  Certificateholder   shall  pay  the
Securities  Administrator a fee equal to $5,000 for such exchange  request.  The Securities  Administrator
shall make the first  distribution on a Certificate in such exchange  transaction on the Distribution Date
in the following month to the  Certificateholder  of record as of the close of business on the last day of
the month of the exchange.]

                  [For Exchanged Certificates]  [As provided in the Agreement and subject to certain limitations
therein set forth, this Certificate is exchangeable for a proportionate interest in one or more Exchangeable
Certificates in a Combination Group.  In connection with each such exchange, the Certificateholder shall pay
the Securities Administrator a fee equal to $5,000 for such exchange request.

                  The  obligations  created by the  Agreement  and the Trust Fund created  thereby  (other
than the  obligations  to make  payments to  Certificateholders  with  respect to the  termination  of the
Agreement)  shall  terminate  upon  the  earlier  of (i) the  making  of the  final  payment  on or  other
liquidation  of the  Underlying  Certificate,  or (ii) the  payment to  Certificateholders  of all amounts
required to be paid to them pursuant to the Agreement.  In no event,  however, will the Trust Fund created
by the  Agreement  continue  beyond  the  expiration  of 21  years  after  the  death of  certain  persons
identified in the Agreement.

                  Unless  this  Certificate  has been  countersigned  by an  authorized  signatory  of the
Securities  Administrator  by manual  signature,  this  Certificate  shall not be  entitled to any benefit
under the Agreement, or be valid for any purpose.

                  IN WITNESS  WHEREOF,  the  Securities  Administrator  has caused this  Certificate to be
duly executed.

                  The Securities Administrator hereby certifies to the Depositor, and its officers,
directors and affiliates, and with the knowledge and intent that they will rely upon this certification,
that:

1.       I have  reviewed  the  annual  report on Form  10-K for the  fiscal  year  [____]  (the  “Annual

material  fact or omit to state a material  fact  necessary to make the  statements  made, in light of the
circumstances  under which such  statements  were made, not misleading  with respect to the period covered
by the Annual  Report,  and (b) the  Securities  Administrator’s  assessment  of  compliance  and  related
attestation  report  referred  to below,  taken as a whole,  do not  contain  any  untrue  statement  of a
material  fact or omit to state a material  fact  necessary to make the  statements  made, in light of the
circumstances  under which such  statements  were made, not misleading  with respect to the period covered
by such assessment of compliance and attestation report;

3.       To my  knowledge,  the  distribution  information  required  to be  provided  by  the  Securities

5.       The report on assessment of  compliance  with  servicing  criteria  applicable to the  Securities

                      SERVICING CRITERIA TO BE ADDRESSED IN ASSESSMENT OF COMPLIANCE

Definitions
Securities Administrator - waterfall calculator
Trustee - fiduciary of the transaction

                  Note: The  definitions  above describe the essential  function that the party  performs,
rather than the party’s  title.  So, for  example,  in a particular  transaction,  the trustee may perform
the  “paying  agent”  and  “securities  administrator”  functions,  while  in  another  transaction, the
securities administrator may perform these functions.

                  Where there are  multiple  checks for  criteria  the  attesting  party will  identify in
their  management  assertion  that they are attesting only to the portion of the  distribution  chain they
are responsible for in the related transaction agreements.

paragraph   of  the  Policy.   Such   payment   shall  be   disbursed   to  the   receiver,   conservator,

payment by the Certificate Insurer under the Policy.

         The  Certificate  Insurer  hereby  agrees that if it shall be subrogated to the rights of Holders
by virtue of any  payment  under this  Policy,  no  recovery of such  payment  will occur  unless the full
amount of the Holders’  allocable  distributions  for such Distribution Date can be made. In so doing, the
Certificate  Insurer does not waive its rights to seek full payment of all  Reimbursement  Amounts owed to
it hereunder or under the Agreement.

         The  Policy  does  not  cover  prepayment  interest  shortfalls,  basis  risk  shortfalls  or any
shortfalls  resulting  from the  application of the Relief Act or similar state laws  attributable  to the
underlying  mortgage  loans  that are  allocated  to the  Underlying  Certificates.  The  Policy  does not
guarantee  to the Holders of the Insured  Certificates  any  particular  rate of  principal  payment.  The
Policy does not cover  shortfalls,  if any,  attributable  to the liability of the underlying  trust,  any
REMIC in the underlying  trust, the underlying  securities  administrator,  the underlying  trustee or any
holder of an Underlying  Certificate  for withholding  taxes, if any (including  interest and penalties in
respect of any liability for withholding  taxes).  The Policy does not cover the failure of the underlying
trustee or the  underlying  securities  administrator  to make any payment  required  under the underlying
pooling  agreement to the holders of the Underlying  Certificates.  The Policy does not cover  shortfalls,
if any,  attributable  to the liability of the Trust,  the  Securities  Administrator,  the Trustee or any
holder of an Insured  Certificate  for  withholding  taxes,  if any  (including  interest and penalties in
respect of any liability for withholding  taxes).  The Policy does not cover the failure of the Trustee or
the Securities  Administrator to make any payment  required under the Pooling  Agreement to the holders of
the Insured Certificates. The Policy does not cover any risk other than Nonpayment as defined below.

         The terms and provisions of the Agreement  constitute  the  instrument of assignment  referred to
in the second paragraph of the face of this Policy.

         A premium  will be payable on this Policy on each  Distribution  Date as provided in Section 3.04
of the Agreement, beginning with the First Distribution Date, in an amount equal to the Premium.

         THE INSURANCE PROVIDED BY THE POLICY IS NOT COVERED BY THE  PROPERTY/CASUALTY  INSURANCE SECURITY
FUND SPECIFIED IN ARTICLE 76 OF THE NEW YORK INSURANCE LAW.

         Nothing  herein  contained  shall  be held to vary,  alter,  waive or  extend  any of the  terms,
conditions,  provisions,  agreements  or  limitations  of the above  mentioned  Policy other than as above
stated.

         To  the  extent  the  provisions  of  this  endorsement  conflict  with  the  provisions  in  the
above-mentioned Policy, the provisions of this endorsement shall govern.

         The Policy and the obligations of the Certificate Insurer thereunder will terminate without any
action on the part of the Certificate Insurer or any other person on the date that is one year and one
day following the earlier to occur of (i) the date on which all amounts required to be paid on the
Insured Certificates have been paid in full and (ii) the Final Distribution Date.  Upon termination of
the Policy, the  Securities Administrator shall deliver the original of the Policy to the Certificate
Insurer.

         No person other than the  Securities Administrator shall be entitled to present the Notice.

         No waiver of any rights or powers of the Certificate Insurer, the Holders, the Securities
Administrator or the Trustee or consent by any of them shall be valid unless signed by an authorized
officer or agent thereof.

         This Policy is issued  under and pursuant to, and shall be  construed  in  accordance  with,  the
laws of the State of New York, without giving effect to the conflict of laws principles thereof.

         The Certificate Insurer’s obligations under the Policy will be discharged to the extent that
funds are received by the Securities Administrator from the Certificate Insurer for payment to the
holders of the Insured Certificates whether or not those funds are properly paid by the Securities
Administrator.  Payments of Insured Amounts will be made only at the time set forth in the Policy, and
no accelerated payments of Insured Amounts will be made at any earlier date under any circumstances,
unless at the sole option of the Certificate Insurer.  The terms of the Insured Certificates do not
permit any acceleration.

         IN WITNESS WHEREOF,  Ambac Assurance  Corporation has caused this endorsement to the Policy to be
signed by its duly authorized officers.

IV. COMPENSATION

          A.   In consideration for providing these Services, MMGP shall pay
               UTEK $120,000 in the form of unregistered shares of common stock
               (1,411,765 shares) upon the execution of this Strategic Alliance
               Agreement. 1/12 of the shares (117,647) shall vest each month
               during the term of this Agreement. In lieu of payment of shares,
               MMGP shall have the option of paying UTEK $10,000 per month for
               the Services described in this Agreement.

               If this Agreement is terminated any unvested shares will be
               returned to MMGP.

          B.   In consideration for the services to be provided herein, MMGP
               agrees that it will remit the agreed upon stock certificate or
               cash payment within five (5) days of both parties executing this
               Agreement. If no consideration is received in the timeline, UTEK
               has the unilateral option to terminate this Agreement.

          C.   MMGP agrees that UTEK shall be entitled to additional
               compensation as follows:

               Technology Transfer: When a technology is shown to MMGP that MMGP
               wants to acquire, UTEK will seek to acquire the license to a
               technology through one of its subsidiaries. UTEK will then seek
               to provide a term sheet to MMGP outlining the consideration to be
               paid by MMGP for the acquisition of this technology. If MMGP
               executes the term sheet, agreeing to the terms set forth, UTEK
               shall transfer this subsidiary to MMGP in a stock for stock
               exchange under an "Agreement and Plan of Acquisition." The
               consideration to be paid by MMGP to UTEK will be based upon a
               markup to the value of the license and other assets in the
               subsidiary as determined by UTEK and agreed to by both parties.

<PAGE>

               provisions of this Agreement shall not be construed as a waiver
               of any subsequent default of the same or similar nature or of any
               other nature.

          J.   INJUNCTIVE RELIEF. Solely by virtue of their respective execution
               of this Agreement and in consideration for the mutual covenants
               of each other, MMGP and UTEK hereby agree, consent and
               acknowledge that, in the event of a breach of any material term
               of this Agreement, the non-breaching party will be without
               adequate remedy-at-law and shall therefore, be entitled to
               immediately redress any material breach of this Agreement by
               temporary or permanent injunctive or mandatory relief obtained in
               an action or proceeding instituted in any court of competent
               jurisdiction without the necessity of proving damages and without
               prejudice to any other remedies which the non-breaching party may
               have at law or in equity.

          K.   ATTORNEY'S FEES. If any arbitration, litigation, action, suit, or
               other proceeding is instituted to remedy, prevent or obtain
               relief from a breach of this Agreement, in relation to a breach
               of this Agreement or pertaining to a declaration of rights under
               this Agreement, the prevailing party will recover all such
               party's attorneys' fees incurred in each and every such action,
               suit or other proceeding, including any and all appeals or
               petitions there from. As used in this Agreement, attorneys' fees
               will be deemed to be the full and actual cost of any legal
               services actually performed in connection with the matters
               involved, including those related to any appeal to the
               enforcement of any judgment calculated on the basis of the usual
               fee charged by attorneys performing such services.

          L.   INVESTMENT COMPANY STATUS. MMGP represents that it is not an
               investment company, registered or unregistered.
