Capitalized   terms used herein but not defined shall have the meanings   ascribed
to them in the Purchase Agreement.

right,   title interest and obligations of Assignor in the Assigned Loans and, as

obligations in, to and under the Purchase   Agreement and Assigned hereby assumes
all rights and obligations with respect to the Assigned Loans under the Purchase

right   title and   interest   in, to or under any   Mortgage   Loans   subject to the
Purchase Agreement other than those set forth on Attachment l. The Company shall
service the Assigned Loans in accordance with the Purchase Agreement as modified
by this AAR Agreement.

Recognition of the Company

      2. From and after   the date   hereof,   the   Company   shall and does   hereby
recognize   that the Assignee   will   transfer   the Assigned   Loans and assign its
rights under the Purchase   Agreement (solely to the extent set forth herein) and
this AAR   Agreement   to HSI Asset Loan   Obligation   Trust   2006-2 (the   "Trust")
created pursuant to a Pooling and Servicing   Agreement,   dated as of November 1,

Servicer"),    Citibank,   N.A.   as   Securities    Administrator   (the   "Securities

the Trust will be the owner of the Assigned   Loans,   (ii) the Company shall look
solely to the Trust for performance of any   obligations of the Assignor   insofar
as   they   relate   to the   enforcement   of the   representations,   warranties   and
covenants with respect to the Assigned   Loans and the Trust hereby   acknowledges
that it has assumed such representations,   warranties and covenants and that any
claim by the Company with respect thereto shall be made by written notice to the
Trustee, (iii) the Trust shall have all the rights and remedies available to the

delivery   requirements and remedies with respect to breaches of   representations
and   warranties   set forth in the Purchase   Agreement,   and shall be entitled to

to the Assigned Loans, and (iv) all references to the Purchaser (insofar as they
relate to the rights, title and interest and, with respect to obligations of the

Agreement insofar as they relate to the Assigned Loans, shall be deemed to refer
to the Trust.   Neither   the   Company   nor the   Assignor   shall amend or agree to
amend, modify,   waiver, or otherwise alter any of the terms or provisions of the

written consent of the Assignee,   the Master Servicer and the Trustee. Any party
requesting such amendment shall provide to the Assignee, the Master Servicer and
the   Trustee,   at its own expense,   an opinion of counsel   stating that (i) such
amendment is permitted   under the terms of the Purchase   Agreement and (ii) such
amendment will not materially and adversely   affect the interests of the holders
of   any   securities    issued   by   the   Trust.   The   Company    acknowledges   that

Loans   pursuant to this AAR Agreement and therefore has the right to enforce all
obligations   of the   Company   as they   relate to the   Assigned   Loans   under the

servicing-retained   basis, and which shall be delivered in groups of whole loans
or participation interests therein, as applicable,   on various dates as provided
herein and in the related Commitment Letter (each, a "Closing Date");

                  WHEREAS, each Mortgage Loan is secured by a mortgage,   deed of
trust   or   other   security   instrument   creating   a first   or   second   lien on a
residential dwelling located in the jurisdiction   indicated on the Mortgage Loan
Schedule for the related Mortgage Loan Package, which is to be annexed hereto on
each Closing Date as Schedule I;

                  WHEREAS,   each of the Co-op   Loans is   secured   by a pledge of
shares of stock issued by a Cooperative   and the   assignment of the   appurtenant
proprietary   lease,   all relating to a specified   dwelling   unit in an apartment
building   owned by the   Cooperative   and located in the states   indicated on the
related Mortgage Loan Schedule; and

                  WHEREAS,   the   Purchaser   and the Seller wish to prescribe the
manner of the conveyance, servicing and control of the Mortgage Loans; and

                  WHEREAS, following its purchase of the Mortgage Loans from the
Seller,   the Purchaser   desires to sell some or all of the Mortgage Loans to not
more   than   five   purchasers   as a   whole   loan   transfer   in a   whole   loan   or
participation   format   or   a   public   or   private    mortgage-backed    securities

registered   on the MERS(R)   System   (defined   below) such that the   mortgagee of
record under each such Mortgage Loan shall be identified as MERS.

                  NOW,   THEREFORE,   in   consideration of the premises and mutual

receipt and sufficiency of which are hereby acknowledged,   the Purchaser and the
Seller agree as follows:

shall have the respective meanings set forth below.

                  Accepted   Servicing   Practices:   With   respect to any Mortgage
Loan, those mortgage servicing practices   (including   collection   procedures) of
prudent mortgage banking   institutions   which service mortgage loans of the same
type as such   Mortgage   Loan in the   jurisdiction   where the   related   Mortgaged
Property is located, which are in accordance with Fannie Mae servicing practices
and   procedures   for MBS pool   mortgages,   as   defined   in the Fannie Mae Guides
including   future   updates,   the terms of the Mortgage   Loan   Documents   and all
applicable federal, state and local legal and regulatory requirements.

                  Adjustable   Rate Mortgage Loan: A Mortgage Loan which provides
for the adjustment of the Mortgage Interest Rate payable in respect thereto.

                  Adjustment Date: With respect to each Adjustable Rate Mortgage
Loan,   the date set forth in the   related   Mortgage   Note on which the   Mortgage
Interest   Rate on such   Adjustable   Rate Mortgage Loan is adjusted in accordance

the purchase price paid for the related Mortgaged Property by the Mortgagor with

Recovery,   and Enforcement Act of 1989, or such collateral assessment acceptable
per the Underwriting Guidelines and acceptable to FNMA and FHLMC. However in the

days prior written notice. If the Initial Purchaser makes such examination prior
to the   related   Closing   Date and   identifies   any   Mortgage   Loans that do not
conform   to the   terms of the   related   Commitment   Letter   or the   Underwriting
Guidelines,   such   Mortgage   Loans may, at the Initial   Purchaser's   option,   be
rejected for purchase by the Initial Purchaser.   If not purchased by the Initial
Purchaser,   such Mortgage Loans shall be deleted from the related   Mortgage Loan
Schedule and any files should be returned within 48 hours. The Initial Purchaser
may, at its option and without notice to the Seller, purchase all or part of any
Mortgage Loan Package   without   conducting any partial or complete   examination.
The fact that the Initial   Purchaser   has   conducted   or has   determined   not to
conduct any   partial or complete   examination   of the   Mortgage   Files shall not
affect the   Initial   Purchaser's   (or any of its   successors')   rights to demand
repurchase or other relief or remedy provided for in this Agreement.

                  SECTION 6.   Conveyance from Seller to Initial Purchaser.

                  Subsection 6.01.    Conveyance of Mortgage Loans; Possession of
                                     Servicing Files.

                   The Seller,   simultaneously   with the payment of the   Purchase
Price,   shall   execute and deliver to the Initial   Purchaser an   Assignment   and
Conveyance   with   respect   to the   related   Mortgage   Loan   Package   in the form
attached   hereto as Exhibit 4. No assignment is required if the Mortgage Loan is
a MOM   Mortgage,   or has   been   previously   assigned   to MERS,   and will   remain
registered on the MERS(R)   System.   The Servicing   File retained by the Servicer
with   respect   to each   Mortgage   Loan   pursuant   to   this   Agreement   shall   be
appropriately   identified in the Servicer's   computer   system to reflect clearly
the sale of such related   Mortgage   Loan to the   Purchaser.   The Servicer   shall
release from its custody the contents of any Servicing   File retained by it only
in   accordance   with this   Agreement,   except   when such   release is required in
connection   with a repurchase   of any such   Mortgage Loan pursuant to Subsection
7.03 or 7.04.

                  Subsection 6.02.    Books and Records.

                  Record title to each Mortgage and the related Mortgage Note as
of the   related   Closing   Date   shall be in the name of the   Seller,   MERS,   the
Purchaser,   the   Custodian   or one or more   designees of the   Purchaser,   as the
Purchaser shall designate.   Notwithstanding the foregoing,   beneficial ownership
of each   Mortgage and the related   Mortgage   Note shall be vested   solely in the
Purchaser or the appropriate designee of the Purchaser,   as the case may be. All
rights   arising out of the   Mortgage   Loans   including,   but not limited to, all
funds received by the Seller after the related   Cut-off Date on or in connection
with a Mortgage   Loan as provided in Section 4 shall be vested in the   Purchaser
or one or more   designees of the   Purchaser;   provided,   however,   that all such
funds received on or in connection with a Mortgage Loan as provided in Section 4
shall   be   received   and held by the   Seller   in trust   for the   benefit   of the
Purchaser or the assignee of the Purchaser,   as the case may be, as the owner of
the Mortgage Loans pursuant to the terms of this Agreement.

                  It   is   the   express    intention    of   the   parties   that   the
transactions   contemplated   by this Agreement be, and be construed as, a sale of
the Mortgage   Loans by the Seller and not a pledge of the Mortgage   Loans by the
Seller to the   Purchaser   to secure a debt or other   obligation   of the   Seller.
Consequently, the sale of each Mortgage Loan shall be reflected as a sale on the
Seller's business records, tax returns and financial   statements.   In the event,
for any reason, any transaction contemplated herein is construed by any court or
regulatory   authority as a borrowing   rather than as a sale,   the Seller and the
Purchaser   intend that the Purchaser or its assignee,   as the case may be, shall
have a perfected   first priority   security   interest in the Mortgage Loans which
may be held by MERS as the nominee for the Purchaser,   the Custodial Account and
the proceeds of any and all of the foregoing   (collectively,   the "Collateral"),
free and clear of adverse   claims.   In such case,   the Seller shall be deemed to
have hereby   granted to the   Purchaser   or its   assignee,   as the case may be, a
first priority security interest in and lien upon the Collateral, free and clear
of   adverse   claims.   In such   event,   the   related   Commitment   Letter and this
Agreement shall constitute a security   agreement,   the Custodian shall be deemed
to be an   independent   custodian   for   purposes of   perfection   of the   security
interest   granted to the Purchaser or its assignee,   as the case may be, and the
Purchaser or its assignee, as the case may be, shall have all of the rights of a
secured party under applicable law.

                  Subsection 6.03.    Delivery of Mortgage Loan Documents.

                  Pursuant to the Custodial   Agreement between the Custodian and
the Initial Purchaser,   the Servicer, shall from time to time in connection with
each Closing   Date,   at least five (5) Business Days prior to such Closing Date,
deliver and release to the Custodian   those   Mortgage Loan Documents as required
by the   Custodial   Agreement   with respect to each Mortgage Loan to be purchased
and sold on the related Closing Date and set forth on the related   Mortgage Loan
Schedule delivered with such Mortgage Loan Documents.

                  The Servicer   shall   provide to each of the   Purchaser and the
Custodian a notice containing a list of authorized   servicing officers (each, an
"Authorized   Representative")   for the purpose of giving and receiving   notices,
requests   and   instructions    and   delivering    certificates   and   documents   in
connection   with   this   Agreement.    Such   notice   shall   contain   the   specimen
signature   for    each   Authorized    Representative.   From    time   to   time,   the
Servicer may,   by   delivering   to   the    others    a     revised    notice,   change
the    information    previously    given     pursuant    to    this     Section,    but

                                        16


<PAGE>


each   of the   parties hereto   shall be entitled to rely conclusively on the then
current notice until receipt of a superseding notice.

                  The   Custodian   shall certify its receipt of all such Mortgage
Loan Documents required to be delivered pursuant to the Custodial   Agreement for
the   related   Closing   Date,   as   evidenced   by the Trust   Receipt   and   Initial
Certification   of the Custodian in the form annexed to the Custodial   Agreement.
The Servicer shall be responsible for maintaining the Custodial Agreement during
the Preliminary Servicing Period.

                  The Servicer shall forward to the Custodian original documents
evidencing   an   assumption,   modification,   consolidation   or   extension   of any
Mortgage Loan entered into in accordance with this Agreement within two weeks of
their   execution,   provided,   however,   that   the   Servicer   shall   provide   the
Custodian   with a   certified   true   copy   of any   such   document   submitted   for
recordation within two weeks of its execution, and shall provide the original of
any document   submitted for recordation or a copy of such document   certified by
the appropriate   public   recording   office to be a true and complete copy of the
original within 240 days of its submission for recordation.

                  Subsection 6.04.    Quality Control Procedures.

                  The Seller shall have an internal quality control program that
verifies, on a regular basis, the existence and accuracy of the legal documents,
credit documents,   property appraisals,   and underwriting decisions. The program
shall include evaluating and monitoring the overall quality of the Seller's loan
production and the servicing   activities of the Seller. The program is to ensure
that the Mortgage Loans are originated and serviced in accordance   with Accepted
Servicing   Standards and the Underwriting   Guidelines;   guard against dishonest,
fraudulent,   or   negligent   acts;   and guard   against   errors and   omissions   by
officers, employees, or other authorized persons.

                  SECTION 7.   Representations, Warranties   and Covenants   of the
Seller: Remedies for Breach.

                  Subsection 7.01.    Representations and   Warranties   Respecting
                                      the Seller.

         otherwise not required under applicable law to effect such licensing or
         qualification   and no demand   for such   licensing or qualification   has
         been   made   upon   the Seller by any such   state,   and   in any event the
         Seller     is    in      compliance    with    the    laws    of     any    such
         state    to    the    extent    necessary   to   ensure   the    enforceability
         of    each    Mortgage    Loan    and    the   servicing   of    the    Mortgage
         Loans    in    accordance    with    the   terms   of    this    Agreement.   No

                                       17


<PAGE>


         licenses or   approvals   obtained by the Seller have been   suspended   or
         revoked by any court, administrative agency, arbitrator or governmental
         body   and   no   proceedings   are   pending   which   might   result in   such

         legal, valid and binding obligation of   the Seller, enforceable against

         may be limited by bankruptcy, insolvency or reorganization;

                        (iii) The execution and   delivery of this   Agreement   by
         the Seller and the performance of and compliance with the terms of this
         Agreement will not violate   the Seller's   articles of   incorporation or
         by-laws   or   constitute   a   default   under or   result   in a   breach   or
         acceleration   of, any material contract,   agreement or other instrument
         to which the Seller is a party or which may be applicable to the Seller
         or its assets;

                        (iv)   The   Seller   is   not   in   violation   of,   and   the
         execution   and   delivery   of   this   Agreement   by   the   Seller   and its
         performance   and compliance   with the terms of this Agreement   will not

         court or any order or regulation of any federal,   state,   municipal   or
         governmental agency having jurisdiction over the Seller   or its assets,
         which   violation   might   have   consequences   that would   materially and
         adversely    affect   the   condition   (financial   or   otherwise)   or   the
         operation of the Seller or its assets or might have   consequences   that
          would    materially   and    adversely   affect   the    performance   of   its
         obligations and duties hereunder;

                        (v)    The Seller is an approved seller/servicer for FNMA
         and FHLMC in good standing and is a HUD approved mortgagee   pursuant to
         Section   203   of   the   National   Housing   Act.   No event   has occurred,
         including   but not limited   to a change in   insurance   coverage,   which
         would   make   the   Seller   unable   to   comply   with   FNMA,   FHLMC or HUD
         eligibility   requirements   or which would require notification to FNMA,
         FHLMC or HUD;

                        (vi)   The Seller does not believe,   nor does it have any
         reason   or cause   to   believe,   that it   cannot   perform each and every
         covenant contained in this Agreement;

                        (vii) The    Mortgage    Loan    Documents   and   any   other
         documents required to be delivered with respect to each   Mortgage   Loan

         Mortgage   Note   and   upon   the   payment   of the   Purchase   Price by the
         Purchaser,   in the event   that the   Seller or MERS as   nominee   for the
         Seller   retains   record   title,   the Seller or MERS as nominee   for the
         Seller shall retain such record   title to each   Mortgage,   each related
         Mortgage Note and the related   Mortgage   Files with respect   thereto in
         trust for the   Purchaser as the owner   thereof and only for the purpose
         of servicing and/or supervising the servicing of each Mortgage Loan;

                        (ix)   There are no   actions or   proceedings   against, or
         investigations of, the Seller before any court,   administrative   agency
         or   other   tribunal   (A)   that   might   prohibit   its entering into this
         Agreement, (B) seeking to prevent   the   sale of the   Mortgage   Loans or
         the consummation of the transactions   contemplated by this Agreement or
         (C)   that   might   prohibit   or   materially   and   adversely   affect   the
         performance by the Seller of its obligations under, or the validity   or
         enforceability of, this Agreement;

                        (x)    No consent, approval, authorization   or   order   of
         any court or governmental agency or body is required for the execution,
         delivery and performance   by the Seller of, or compliance by the Seller

                        (xi)   The consummation of the transactions   contemplated
         by this Agreement are in the ordinary course of business of the Seller,
         and the transfer, assignment and   conveyance of the Mortgage   Notes and

                        (xii) The   transfer   of   the   Mortgage   Loans   shall   be
         treated   as   a   sale   on   the books and records of the Seller,   and the
         Seller   has   determined   that,   and   will treat, the disposition of the
         Mortgage   Loans   pursuant   to   this   Agreement for   tax and   accounting
         purposes   as a sale. The Seller shall maintain a complete   set of books
         and   records for   each Mortgage Loan   which shall   be clearly marked to
         reflect the ownership of each Mortgage Loan by the Purchaser;

                        (xiii) The   consideration   received   by the   Seller upon
         the   sale   of   the   Mortgage   Loans constitutes fair   consideration and

                        (xiv) The   Seller is   solvent and will   not be   rendered
         insolvent   by the consummation of the transactions contemplated hereby.
         The Seller is not   transferring   any   Mortgage   Loan with any intent to

         underwritten     to   the   same   standards   as   the   Mortgage   Loans   and
         covering      mortgaged       properties     similar    to    the    Mortgaged
         Properties, is true and correct in all material respects;

                                       19

                        (xvi) Neither this Agreement nor any written   statement,
          report or other document   prepared and   furnished or to be prepared and
         furnished   by the   Seller pursuant   to this   Agreement or in connection

         with the rules and procedures of MERS in connection with the   servicing
         of the Mortgage Loans that are registered with MERS; and

                        (iii) All   payments   required to be made up to the close
         of business on the related   Closing Date for such   Mortgage   Loan under
         the terms of the   Mortgage   Note have been   made;   the   Seller   has not
         advanced funds, or induced, solicited or knowingly received any advance
         of funds   from a party   other than the owner of the   related   Mortgaged
         Property,   directly   or   indirectly,   for   the   payment   of any   amount
         required by the Mortgage   Note or Mortgage.   No Mortgage   Loan has been
         thirty   (30)   days   or   more    delinquent   in   any   payment   since   the
         origination of such Mortgage Loan;

                        (iv)   There are no delinquent taxes, ground rents, water
         charges,   sewer    rents,   assessments,   insurance   premiums,   leasehold
         payments or other   outstanding charges   affecting the related Mortgaged
         Property;

                        (v)    The   terms of   the Mortgage   Note and the Mortgage
         have   not   been   impaired,   waived, altered or modified in any respect,
         except   by   written   instruments,   recorded   in   the   applicable public
         recording    office    if    necessary    to   maintain   the   lien   priority
         of the Mortgage, and which have been   delivered    to    the    Custodian;
         the   substance   of   any    such   waiver,    alteration    or   modification
         has    been   approved    by   the   insurer   under   the   Primary   Insurance
         Policy,    if   any,    and   has   been   approved   by   the   title   insurer,
         to   the   extent   required   by   the   related   policy,   and   is reflected
         on   the   related   Mortgage   Loan   Schedule.   No   instrument   of waiver,
         alteration or modification has been executed, and no Mortgagor has been
         released, in whole or in part, except in connection   with an assumption

                                       20


<PAGE>


         agreement   approved   by the insurer under the Primary Insurance Policy,
         if any, and by the title insurer, to the extent required by the policy,
         and   the   terms   of   which   are   reflected in the related Mortgage Loan
         Schedule;

                        (vi)   The Mortgage Note and the Mortgage are not subject
         to any right of rescission, set-off, counterclaim or defense, including
         the defense of usury, nor will the operation of any of the terms of the
         Mortgage    Note   and   the   Mortgage,   or   the   exercise   of   any   right
         thereunder,   render   the   Mortgage   unenforceable, in whole or in part,
         or   subject   to   any   right   of   rescission,   set-off,   counterclaim or
         defense,    including   the   defense   of   usury   and   no   such   right   of
         rescission,   set-off,   counterclaim or defense has been   asserted   with
         respect   thereto.   Each   Prepayment   Charge or penalty with respect   to
         any Mortgage Loan is   permissible,   enforceable and   collectible   under
         applicable federal, state and local law;

                        (vii) All   buildings   upon the   Mortgaged   Property   are
          insured   by   an   insurer   acceptable   to FNMA and FHLMC against loss by
         fire,   hazards   of   extended    coverage and   such other   hazards as are
         customary   in   the   area   where   the    Mortgaged   Property   is located,
         pursuant to the Servicing Addendum. All such insurance policies contain
         a standard   mortgagee   clause naming the Servicer,   its successors   and
         assigns as mortgagee and all premiums   thereon   have been paid.   If the
         Mortgaged   Property   is in an area identified   on a Flood Hazard Map or
         Flood   Insurance   Rate Map issued by the Federal   Emergency   Management
         Agency   as having   special flood hazards (and such flood   insurance has
         been made available) a flood insurance policy meeting the   requirements
         of the current   guidelines of the Federal   Insurance   Administration is
         in   effect which policy conforms to the requirements of FNMA and FHLMC.
         The   Mortgage   obligates the Mortgagor   thereunder to maintain all such
         insurance at the Mortgagor's cost and expense,   and on the   Mortgagor's
         failure   to do so,   authorizes   the   holder of the Mortgage to maintain
         such   insurance   at   Mortgagor's   cost    and   expense    and    to    seek
         reimbursement therefor from the Mortgagor;

                        (viii) Any and all requirements of any federal, state or
         local    law   applicable   to   the   Mortgage   Loans   including,    without
         limitation, usury, truth in lending, real estate settlement procedures,
         predatory and abusive lending, consumer credit protection, equal credit
         opportunity,   fair   housing   or    disclosure   laws   applicable   to   the
         origination   and servicing of mortgage   loans of a type   similar to the
         Mortgage   Loans have been complied with;

                        (ix) The   Mortgage   has not been   satisfied,   cancelled,
         subordinated   or   rescinded,   in whole or in   part,   and the   Mortgaged
          Property has not been released from the lien of the Mortgage,   in whole
         or in part, nor has any instrument   been executed that would effect any
         such satisfaction, cancellation, subordination, rescission or release;

                         (x)    Except   with   respect   to   each   Co-op   Loan,   the
         related   Mortgage is   properly   recorded   and is a valid,   existing and
         enforceable (A) first lien and first priority   security   interest   with
         respect    to    each    Mortgage    Loan    which    is    indicated    by the
         Seller     on     the     Mortgage   Loan    Schedule    on    the    Mortgaged
         Property,     including    all improvements   on   the   Mortgaged   Property
         subject      only     to     (a)      the     lien     of      current      real
         property    taxes   and   assessments   not   yet    due    and    payable, (b)
         covenants,   conditions and restrictions, rights of way, easements    and
         other matters   of   the   public record as of the date of recording being

                                       21


<PAGE>


         acceptable to mortgage lending   institutions generally and specifically
         referred   to    in   the   lender's   title   insurance   policy delivered to
         the   originator of the Mortgage Loan and which do not adversely   affect
         the   Appraised   Value of the Mortgaged   Property,   (c) other matters to
         which like   properties   are commonly   subject   which do not   materially
         interfere   with the benefits of the security intended to be provided by
         the   Mortgage   or   the   use,   enjoyment,   value or marketability of the
         related   Mortgaged   Property, (d)   with   respect   to   each   Second Lien
         Mortgage   a prior mortgage lien on the Mortgage   Property.   Except with
         respect to each Co-op Loan, any security   agreement,   chattel   mortgage
         or equivalent   document related to and delivered in connection with the
         Mortgage Loan establishes and creates a valid, existing and enforceable
         (A) first lien and first priority   security   interest   with   respect to
         each first lien Mortgage   Loan, or (B) second lien and second   priority
         security   interest   with respect to each second lien Mortgage   Loan, in
         either case, on the property described   therein and the Seller has full
         right   to sell   and   assign   the same to the   Purchaser.   The Mortgaged
         Property   was   not, as of the date of origination of the Mortgage Loan,
         subject   to   a   mortgage,   deed   of trust, deed to secure debt or other
         security   instrument   creating   a lien subordinate to   the   lien of the
         Mortgage.    With   respect to each Co-op Loan,   the related   Mortgage is
         a valid,   enforceable and   subsisting first or second security interest
         on   the   related   Cooperative   Shares   securing the related cooperative
         note,    subject    only   to (a) liens   of   the   Cooperative   for   unpaid
         assessments     representing    the    Mortgagor's    pro rata   share of the
         Cooperative's   payments   for its blanket   mortgage,   current and future
         real   property taxes,   insurance   premiums,   maintenance fees and other
         assessments to which like collateral is commonly   subject and (b) other
         matters   to   which   like   collateral   is commonly   subject which do not
         materially   interfere   with the   benefits of the   security   intended to
         be provided by the   Security   Agreement. There are no liens   against or
         security   interest   in the   cooperative   shares   relating to each Co-op
         Loan (except for unpaid maintenance, assessments and other amounts owed
         to the related cooperative which   individually or in the aggregate will
         not have a   material   adverse   effect on such Co-op   Loan),   which have
         priority   over   the   Seller's   security   interest   in   such Cooperative
         Shares;

                        (xi)   The   Mortgage   Note   and the related   Mortgage are
         genuine   and   each   is   the legal, valid and binding   obligation of the
         maker thereof,   enforceable in accordance with its terms;

                        (xii) All   parties to the Mortgage Note and the Mortgage

         right to transfer and sell the Mortgage Loan to the Purchaser   free and
         clear   of   any   encumbrance,   equity,   lien,   pledge,   charge, claim or
         security interest;

                        (xv)   All   parties   which   have   had any interest in the
         Mortgage   Loan, whether as mortgagee, assignee,   pledgee or   otherwise,

          the Mortgaged Property is located;

                        (xvi) Except   with   respect   to   each   Co-op   Loan,   the
         Mortgage Loan,   that is a first   lien,   is covered by an American   Land
         Title Association ("ALTA")   lender's   title   insurance   policy   (which,
         in the case of an Adjustable Rate Mortgage Loan has an adjustable   rate
         mortgage   endorsement   in   the   form   of   ALTA   6.0 or 6.1)   acceptable

         insurance   policy is in full force and effect and will be in full force

         default, breach, violation or event of acceleration existing under such
         first    lien    mortgage    or    the   related    mortgage    note    at   the
         time of   origination,   (iii)   no    event   which,    with    the    passage
         of    time    or    with    notice    and    the    expiration of any grace or
         cure   period,   would   constitute   a default, breach, violation or event
         of    acceleration     thereunder,   (iv)   either   (A)   the    first    lien
         mortgage   contains   a   provision    which   allows or   (B) applicable law

         the first lien mortgage and (v) either no consent for the Mortgage Loan
         is   required   by the holder of the first lien or such   consent has been
         obtained and is contained in the Mortgage File;

                        (xviii) There   are   no   mechanics' or   similar   liens or
         claims which have been filed for work, labor or material (and no rights

         the related Mortgaged Property which are or may be liens   prior   to, or
         equal or coordinate with, the lien of the related Mortgage;

                         (xix) All    improvements    which    were    considered   in
         determining   the Appraised Value of   the   related   Mortgaged    Property
         lay   wholly   within   the boundaries and building   restriction   lines of
         the   Mortgaged   Property,   and   no improvements on adjoining properties
         encroach upon the Mortgaged Property;

                        (xx)   The Mortgage   Loan was originated by the Seller or
         by a savings and loan association, a savings bank,   a   commercial   bank
         or similar   banking institution which is   supervised   and   examined   by
         a federal or state authority, or by a mortgagee approved as such by the
         Secretary of HUD,   Fannie Mae or Freddie Mac or by a mortgage banker or
         broker licensed or authorized   to   originate    mortgage   loans   and   do
         business in the jurisdiction in which the   related   Mortgaged   Property
         is   located, applying   substantially   the same   underwriting   standards
         used   by   the   Seller   and   in   a manner that in all respects meets the
         requirements   of the Secondary Mortgage Market Enhancement Act of 1984,

         Interest   Rate   and (C)   in the case of a Balloon Loan,   are based on a
         fifteen (15) or thirty (30) year   amortization   schedule,   as set forth
         in the related Mortgage Note, and a final monthly payment substantially
         greater   than   the   preceding    monthly   payment which is sufficient to
         amortize the remaining principal balance of the Balloon Loan and to pay
         interest   at the related   Mortgage   Interest   Rate.   The Index for each
         Adjustable   Rate Mortgage Loan is as defined in the related   Commitment
         Letter     and     the    Mortgage     Loan     Schedule.     The     Mortgage
         Note       does     not     permit     negative      amortization,     unless
