                  SALE OF MORTGAGE LOANS AND RELATED PROVISIONS

          Section 2.01  Sale of Initial Mortgage Loans and MI Policies.
                        -----------------------------------------------

          (a)  The Seller hereby sells, and the Company hereby purchases on the
Closing Date the Initial Mortgage Loans identified (and the related MI Policies)
on the Mortgage Loan Schedule annexed hereto as Exhibit 1, the proceeds thereof
and all rights under the Related Documents (including the related Mortgage
Files). The Initial Mortgage Loans consist of a pool of two groups of
conventional, residential first lien mortgage loans with fixed and adjustable
interest rates, the Group I Mortgage Loans and the Group II Mortgage Loans, and
a group of residential first and second lien mortgage loans with fixed and
adjustable interest rates, the Group III Mortgage Loans. The Initial Mortgage
Loans will have a Principal Balance as of the close of business on the Cut-off
Date, after giving effect to any payments due on or before such date whether or
not received, of approximately $1,019,921,947. The sale of the Initial Mortgage
Loans will take place on the Closing Date, subject to and simultaneously with
the deposit of the Initial Mortgage Loans and the Original Pre-Funded Amount
into the Trust Fund, the issuance of the Certificates by the Trustee and the
sale of the Underwritten Certificates pursuant to the Underwriting Agreement.
The purchase price (the "Purchase Price") for the Initial Mortgage Loans to be
paid by the Company to the Seller on the Closing Date is the unpaid principal
balance of the Initial Mortgage Loans less any unreimbursed advances plus
accrued and unpaid interest plus any costs and damages incurred in connection
with the violation of any Initial Mortgage Loan of any predatory or abusive
lending law. The Purchase Price shall consist of the following:

               (i)   a payment in an amount equal to $1,477,448,044 representing
the net proceeds of the sale of the Underwritten Certificates, which payment
shall be paid to the Seller by wire transfer in immediately available funds on
the Closing Date by or on behalf of the Company, or as otherwise agreed by the
Company; and

               (ii)  a payment in an amount equal to $15,000,000 representing
the proceeds of the sale of the Class O Certificates, the Class P and Class X
Certificates (including the net value represented by the Class I Certificates)
by the Company to NCFC pursuant to the REMIC Interests Sale Agreement, which
payment shall be paid to the Seller by wire transfer in immediately available
funds on the Closing Date by or on behalf of the Company, or as otherwise agreed
by the Company.

          (b)  [Reserved]

          (c)  In connection with such conveyances by the Seller, the Seller
shall on behalf of and at the direction of the Company deliver to, and deposit
with the Custodian on behalf of the Trustee, on or before the Closing Date in
the case of a Initial Mortgage Loan and two Business Days prior to the related
Subsequent Transfer Date in the case of a Subsequent Mortgage Loan, the
following documents or instruments with respect to each Mortgage Loan (the
"Mortgage File"):

                                       2

<PAGE>

               (i)   the original Mortgage Note endorsed to "JPMorgan Chase
Bank, as Trustee of the NovaStar Mortgage Funding Trust, Series 2003-4, relating
to the NovaStar Home Equity Loan Asset-Backed Certificates, Series 2003-4";

               (ii)  the original Mortgage with evidence of recording thereon,
or, if the original Mortgage has not yet been returned from the public recording
office, a copy of the original Mortgage certified by the Seller or the public
recording office in which such original Mortgage has been recorded and if the
Mortgage Loan is registered on the MERS System, such Mortgage shall include
thereon a statement that it is a MOM Loan and shall include the MIN for such
Mortgage Loan;

               (iii) unless the Mortgage Loan is registered on the MERS System,
an original assignment (which may be included in one or more blanket assignments
if permitted by applicable law) of the Mortgage endorsed to "JPMorgan Chase
Bank, as Trustee of the NovaStar Mortgage Funding Trust, Series 2003-4, relating
to the NovaStar Home Equity Loan Asset-Backed Certificates, Series 2003-4", and
otherwise in recordable form;

               (iv)  originals of any intervening assignments of the Mortgage
showing an unbroken chain of title from the originator thereof to the Person
assigning it to the Trustee (or to MERS, if the Mortgage Loan is registered on
the MERS System, and noting the presence of a MIN, if the Mortgage Loan is
registered on the MERS System), with evidence of recording thereon, or, if the
original of any such intervening assignment has not yet been returned from the
public recording office, a copy of such original intervening assignment
certified by the Seller or the public recording office in which such original
intervening assignment has been recorded;

               (v)   the original policy of title insurance (or a commitment for
title insurance, if the policy is being held by the title insurance company
pending recordation of the Mortgage);

               (vi)  true and correct copy of each assumption, modification,
consolidation or substitution agreement, if any, relating to the Mortgage Loan;
and

               (vii) an executed copy of the notice of assignment and
acknowledgement of assignment with respect to the Mortgage Loans covered by the
MI Policies.

          If a material defect in any Mortgage File is discovered which may
materially and adversely affect the value of the related Mortgage Loan, or the
interests of the Trustee (as pledgee of the Mortgage Loans), or the
Certificateholders in such Mortgage Loan, including if any document required to
be delivered to the Custodian has not been delivered (provided that a Mortgage
File will not be deemed to contain a defect for an unrecorded assignment under
clause (i) above for 180 days following submission of the assignment if the
Seller has submitted such assignment for recording pursuant to the terms of the
following paragraph), the Seller shall cure such defect, repurchase the related
Mortgage Loan at the Repurchase Price or substitute an Eligible Substitute
Mortgage Loan for the related Mortgage Loan upon the same terms and conditions
set forth in Section 3.01 hereof as to the Initial Mortgage Loans and the
Subsequent Mortgage Loans and Section 2.02(c) hereof as to the Subsequent
Mortgage Loans for breaches of representations and warranties.

                                       3

<PAGE>

          Promptly after the Closing Date in the case of a Initial Mortgage Loan
or, in the case of a Subsequent Mortgage Loan, promptly after the Subsequent
Transfer Date (or after the date of transfer of any Eligible Substitute Mortgage
Loan), the Seller at its own expense shall complete and submit for recording in
the appropriate public office for real property records each of the assignments
referred to in clause (i) above, with such assignment completed in favor of the
Trustee, excluding any Mortgage Loan that is registered on the MERS System if
MERS is identified on the Mortgage or on a properly recorded assignment of
Mortgage as the mortgagee of record. While such assignment to be recorded is
being recorded, the Custodian shall retain a photocopy of such assignment. If
any assignment is lost or returned unrecorded to the Custodian because of any
defect therein, the Seller is required to prepare a substitute assignment or
cure such defect, as the case may be, and the Seller shall cause such substitute
assignment to be recorded in accordance with this paragraph.

          In instances where an original Mortgage or any original intervening
assignment of Mortgage is not, in accordance with clause (ii) or (iv) above,
delivered by the Seller to the Custodian, on behalf of the Trustee, prior to or
on the Closing Date in the case of a Initial Mortgage Loan or, in the case of a
Subsequent Mortgage Loan, prior to or on the Subsequent Transfer Date, the
Seller will deliver or cause to be delivered the originals of such documents to
the Custodian, on behalf of the Trustee, promptly upon receipt thereof.

          In connection with the assignment of any Initial Mortgage Loan
registered on the MERS System, promptly after the Closing Date, the Seller
further agrees that it will cause, at the Seller's own expense, the MERS System
to indicate that such Initial Mortgage Loan has been assigned by the Seller to
the Trustee in accordance with this Agreement for the benefit of the
Certificateholders by including in such computer files (a) the applicable
Trustee code in the field "Trustee" which identifies the Trustee and (b) the
code "NovaStar 2003-4" (or its equivalent) in the field "Pool Field" which
identifies the series of the Certificates issued in connection with such
Mortgage Loans.

          Effective on the Closing Date, the Company hereby acknowledges its
acceptance of all right, title and interest to the Initial Mortgage Loans and
other property, existing on the Closing Date and thereafter created and conveyed
to it pursuant to this Section 2.01.

          The Trustee, as assignee or transferee of the Company, shall be
entitled to all scheduled principal payments due after the Cut-off Date, all
other payments of principal due and collected after the Cut-off Date, and all
payments of interest on the Initial Mortgage Loans. No scheduled payments of
principal due on or before the Cut-off Date and collected after the Cut-off Date
shall belong to the Company pursuant to the terms of this Purchase Agreement.
The Pooling and Servicing Agreement shall provide that any late payment charges
collected in connection with a Mortgage Loan shall be paid to the Servicer as
provided therein.

          (d)  The parties hereto intend that the transactions set forth herein
constitute a sale by the Seller to the Company on the Closing Date of all the
Seller's right, title and interest in and to the Initial Mortgage Loans and
other property as and to the extent described above. In the event the
transactions set forth herein shall be deemed not to be a sale, the Seller
hereby grants to the Company as of the Closing Date a security interest in all
of the Seller's right, title and interest in, to and under the Initial Mortgage
Loans and such other property, to secure all of the Seller's

                                       4

<PAGE>

obligations hereunder and this Purchase Agreement shall constitute a security
agreement under applicable law and in such event, the parties hereto acknowledge
that the Custodian, in addition to holding the Initial Mortgage Loans on behalf
of the Trustee for the benefit of the Certificateholders, holds the Initial
Mortgage Loans as designee of the Company. The Seller agrees to take or cause to
be taken such actions and to execute such documents, including without
limitation the filing of all necessary UCC-1 financing statements filed in the
Commonwealth of Virginia (which shall have been submitted for filing as of the
Closing Date and each Subsequent Transfer Date, as applicable), any continuation
statements with respect thereto and any amendments thereto required to reflect a
change in the name or corporate structure of the Seller, as are necessary to
perfect and protect the interests of the Company and their respective assignees
in each Initial Mortgage Loan and the proceeds thereof and the interests of the
Trustee and its assignees in each Subsequent Mortgage Loan and the proceeds
thereof. The Company agrees to take or cause to be taken such actions and to
execute such documents, including without limitation the filing of all necessary
UCC-1 financing statements, and continuation statements with respect thereto and
any amendments thereto as are necessary to perfect and protect the interests of
the Trustee and its assignees in each Initial Mortgage Loan.

          Section 2.02  Conveyance of the Subsequent Mortgage Loans.
                        -------------------------------------------

          (a)  Subject to the conditions set forth in paragraph (b) below in
consideration of the Trustee's delivery on the related Subsequent Transfer Dates
of all or a portion of the balance of funds in the Pre-Funding Account, the
Seller shall on any Subsequent Transfer Date sell, transfer, assign, set over
and convey, without recourse, to the Company, who shall then sell, transfer,
assign, set over and convey, without recourse, to the Trustee, but subject to
the other terms and provisions of this Purchase Agreement, all of the right,
title and interest of the Seller in and to (i) the Subsequent Mortgage Loans
(and the related MI Policies) identified on the related Mortgage Loan Schedule
attached to the related Subsequent Transfer Instrument delivered by the Seller
on such Subsequent Transfer Date, (ii) principal due and interest accruing on
the Subsequent Mortgage Loans after the related Subsequent Cut-off Date and (i)
with respect to such Subsequent Mortgage Loans all items to be delivered
pursuant to Section 2.01(c) above and the other items in the related Mortgage
Files; provided, however, that the Seller reserves and retains all right, title
and interest in and to principal received and interest accruing on the
Subsequent Mortgage Loans prior to the related Subsequent Cut-off Date. The
transfer by the Seller to the Company, and by the Company to the Trustee, of the
Subsequent Mortgage Loans identified on each Mortgage Loan Schedule attached to
the related Subsequent Transfer Instrument shall be absolute and is intended by
the Trustee, the Company and the Seller to constitute and to be treated as a
sale of the Subsequent Mortgage Loans by the Seller to the Company, and a sale
of the Subsequent Mortgage Loans by the Company to the Trustee.

          In the event such transactions shall be deemed not to be a sale, the
Seller hereby grants to the Company as of each Subsequent Transfer Date a
security interest in all of the Seller's right, title and interest in, to and
under the related Subsequent Mortgage Loans and such other property, to secure
all of the Seller's obligations hereunder, and this Purchase Agreement shall
constitute a security agreement under applicable law, and in such event, the
parties hereto acknowledge that the Custodian, in addition to holding the
Subsequent Mortgage Loans and the related MI Policies on behalf of the Trustee
for the benefit of the Certificateholders, holds the Subsequent Mortgage Loans
and the related MI Policies as designee of the Company. The Seller

                                       5

<PAGE>

agrees to take or cause to be taken such actions and to execute such documents,
including without limitation the filing of all necessary UCC-1 financing
statements filed in the Commonwealth of Virginia (which shall be submitted for
filing as of the related Subsequent Transfer Date), any continuation statements
with respect thereto and any amendments thereto required to reflect a change in
the name or corporate structure of the Seller or the filing of any additional
UCC-1 financing statements due to a change in the state of incorporation of the
Seller as are necessary to perfect and protect the interests of the Company and
its assignees in the Subsequent Mortgage Loans.

          In the event such transactions shall be deemed not to be a sale, the
Company hereby grants to the Trustee as of each Subsequent Transfer Date a
security interest in all of the Company's right, title and interest in, to and
under the related Subsequent Mortgage Loans and such other property, to secure
all of the Company's obligations hereunder, and this Purchase Agreement shall
constitute a security agreement under applicable law, and in such event, the
parties hereto acknowledge that the Custodian, in addition to holding the
Subsequent Mortgage Loans and the related MI Policies on behalf of the Trustee
for the benefit of the Certificateholders, holds the Subsequent Mortgage Loans
and the related MI Policies as designee of the Trustee. The Company agrees to
take or cause to be taken such actions and to execute such documents, including
without limitation, the filing of all necessary UCC-1 financing statements filed
in the State of Delaware (which shall be submitted for filing as of the related
Subsequent Transfer Date), any continuation statements with respect thereto and
any amendments thereto required to reflect a change in the name or corporate
structure of the Company or the filing of any additional UCC-1 financing
statements due to a change in the state of incorporation of the Company as are
necessary to perfect and protect the interests of the Trustee and its assignees
in Subsequent Mortgage Loans.

          The related Mortgage File for each Subsequent Mortgage Loan shall be
delivered to the Custodian, on behalf of the Trustee, prior to the related
Subsequent Transfer Date.

          The Trustee on each Subsequent Transfer Date shall acknowledge by
signing receipt thereof its acceptance of all right, title and interest to the
related Subsequent Mortgage Loans and other property, existing on the Subsequent
Transfer Date and thereafter created, conveyed to it pursuant to this Section
2.02.

          The Trustee, as trustee of the Trust Fund, shall be entitled to all
scheduled principal payments due after each Subsequent Cut-off Date, all other
payments of principal due and collected after each related Subsequent Cut-off
Date, and all payments of interest on the Subsequent Mortgage Loans, minus that
portion of any such payment which is allocable to the period prior to the
related Subsequent Cut-off Date. No scheduled payments of principal due on or
before the related Subsequent Cut-off Date and collected after the related
Subsequent Cut-off Date shall belong to the Trust Fund pursuant to the terms of
this Purchase Agreement.

          The purchase price paid by the Trustee, at the direction of the
Servicer and on behalf of the Trustee, from amounts released from the
Pre-Funding Account shall be one-hundred percent (100%) of the aggregate
Principal Balances of the Subsequent Mortgage Loans so transferred (as
identified on the Mortgage Loan Schedule attached to the related Subsequent
Transfer Instrument provided by the Seller).

                                       6

          (b)  The Seller shall transfer to the Company, who shall transfer to
the Trustee, the Subsequent Mortgage Loans and the other property and rights
related thereto described in Section 2.02(a) above, and the Trustee shall cause

insolvent by such transfers, nor shall they be aware of any pending insolvency;

               (iv)  such sale and transfer (i) does not cause any REMIC created
under the Pooling and Servicing Agreement to fail to qualify as a REMIC and (ii)
is not a prohibited transaction within the meaning of Section 860F(a)(2) of the
Code or a contribution resulting in a tax under Section 860G(d) of the Code,

commitment binder or commitment to issue the same was effective on the date of
the origination of each Mortgage Loan, each such policy is valid and remains in
full force and effect, and each such policy was issued by a title insurer
qualified to do business in the jurisdiction where the Mortgaged Property is
located, which policy insures the Seller and successor owners of indebtedness
secured by the insured Mortgage as to the first priority lien of the Mortgage as
applicable. The Seller is, and such successor owners will be, the sole insured
under such lender's title insurance policy; no claims have been made under such
mortgage title insurance policy; no prior holder of the applicable Mortgage,
including the Seller, has done, by act or omission, anything which would impair
the coverage of such mortgage title insurance policy; and each such policy,
binder or assurance contains all applicable endorsements;

               (xxiii)    All of the improvements which were included for the
purpose of determining the Appraised Value of the Mortgaged Property lie wholly
within the boundaries and building restriction lines of such property and no
improvements on adjoining properties encroach upon the Mortgaged Property;

               (xxiv)     No improvement located on or being part of the
Mortgaged Property is in violation of any applicable zoning law or regulation,

a material adverse effect on the market value of the Mortgaged Property;

               (xxv)      Each Mortgage Note and the applicable Mortgage are
genuine, and each is the legal, valid and binding obligation of the maker
thereof, enforceable in accordance with its terms, except as limited by
bankruptcy, insolvency, reorganization, moratorium, receivership and other
similar laws relating to creditors' rights generally or by equitable principles
(regardless of whether such enforcement is considered in a proceeding in equity
or at law). All parties to the Mortgage Note and the Mortgage had legal capacity

<PAGE>

execute the Mortgage Note and the Mortgage and each Mortgage Note and Mortgage
has been duly and properly executed by such parties;

disbursed, there is no requirement for future advances thereunder and any and
all requirements as to completion of any on-site or off-site improvements and as
to disbursement of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making, closing or recording the Mortgage Loans
were paid and the Mortgagor is not entitled to any refund of amounts paid or due
under the Mortgage Note;

               (xxvii)    Each Mortgage contains customary and enforceable
provisions that render the rights and remedies of the holder thereof adequate
for the realization against the Mortgaged Property of the benefits of the
security, including (i) in the case of a Mortgage designated as a deed of trust,
by trustee's sale, and (ii) otherwise by judicial foreclosure or if applicable,
non-judicial foreclosure. Upon default by a Mortgagor on a Mortgage Loan and
foreclosure on, or trustee's sale of, the Mortgaged Property pursuant to the
proper procedures, the holder of the Mortgage Loan will be able to deliver good
and merchantable title to the property, subject to any applicable rights of
redemption;

covered by a valid and existing hazard insurance policy substantially acceptable
to FNMA and acceptable to the Seller which policy provides for fire extended
coverage and such other hazards as are customary in the area where the Mortgaged
Property is located representing coverage in an amount not less than the lesser
of (A) the maximum insurable value of the improvements securing such Mortgage
Loan and (B) the outstanding Principal Balance of the related Mortgage Loan; if
the improvement on the Mortgaged Property is a condominium unit, it is included
under the coverage afforded by a blanket policy for the condominium project. All

interest, as mortgagee, and the Seller has received no notice that any premiums
due and payable thereon have not been paid; the Mortgage obligates the Mortgagor
thereunder to maintain all such insurance at the Mortgagor's cost and expense,
and upon the Mortgagor's failure to do so, authorizes the holder of the Mortgage
to obtain and maintain such insurance at the Mortgagor's cost and expense and to
seek reimbursement therefor from the Mortgagor. There has been no act or
omission which would impair the coverage of any such policy, the benefits of the
endorsement provided for herein, or the validity and binding effect of either;

carrier in an amount representing coverage not less than the least of (A) the
outstanding Principal Balance of the Mortgage Loan, (B) the minimum amount
required to compensate for damage or loss on a replacement cost basis and (C)
the maximum amount of flood coverage that is available under federal law;

               (xxxiii)   Except for the Mortgage Loan referred to in clause
(xii) as being delinquent, there is no material monetary default, breach,
violation or event of acceleration existing under the Mortgage or the applicable
Mortgage Note; and no material event which, with the passage of time or with
notice and the expiration of any grace or cure period, would constitute a
material default, breach, violation or event of acceleration, and neither the

Mortgage Loan has waived any default, breach, violation or event of
acceleration; no foreclosure action is threatened or has been commenced with

the case of a Initial Mortgage Loan and as of the related Subsequent Transfer
Date in the case of a Subsequent Mortgage Loan, with respect to any Mortgage
Loan have been consolidated with the outstanding principal amount secured by
such Mortgage, and the secured principal amount, as consolidated, bears a single
interest rate and single repayment term reflected on the Mortgage Loan Schedule.
The consolidated principal amount does not exceed the original principal amount
of the Mortgage Loan. The Mortgage Note with respect to any Mortgage Loan does
not permit or obligate the Servicer to make future advances to the Mortgagor at
the option of the Mortgagor;

               (xxxvii)   The Seller has caused or will cause to be performed
any and all acts required to preserve the rights and remedies of the Company and
the Trustee evidencing an interest in the Mortgage Loans in any insurance
policies applicable to the Mortgage Loans including, without limitation, any
necessary notifications of insurers,

                                       17

herein set forth in this Section 3.01(b), to the extent set forth in the
definition of "Eligible Substitute Mortgage Loan", as of the date of
substitution, and the Seller shall be obligated to repurchase or substitute for
any Eligible Substitute Mortgage Loan as to which a Repurchase Event has
occurred as provided herein. In connection with the substitution of one or more
Eligible Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the
Servicer will determine the amount (such amount, a "Substitution Adjustment
Amount"), if any, by which the aggregate principal balance of all such Eligible
Substitute Mortgage Loans as of the date of substitution is less than the
aggregate principal balance of all such Deleted Mortgage Loans (after
application of the principal portion of the Monthly Payments due in the month of
substitution that are to be distributed to the Payment Account in the month of
substitution). The Seller shall pay the amount of such shortfall to the Servicer
for deposit into the Collection Account on the day of substitution, without any
reimbursement therefor.

          Upon receipt by the Trustee of written notification, signed by a
Servicing Officer, of the deposit of such Repurchase Price or of such
substitution of an Eligible Substitute Mortgage Loan and deposit of any
applicable Substitution Adjustment Amount as provided above, the Custodian
shall, on behalf of the Trustee, cause to be released to the Seller the related
Mortgage File for the Mortgage Loan being repurchased or substituted for and the
Trustee shall execute and deliver such instruments of transfer or assignment
prepared by the Servicer, in each case without recourse, as shall be necessary
to vest in the Seller or its designee such Mortgage Loan released pursuant
hereto and thereafter such Mortgage Loan shall not be an asset of the Trustee.

          It is understood and agreed that the obligation of the Seller to cure
any breach with respect to or to repurchase or substitute for, any Mortgage Loan
as to which such a breach has occurred and is continuing shall, except to the
extent provided in Section 6.01 of this Purchase Agreement, constitute the sole
remedy respecting such breach available to the Company, the Trustee, the
Certificateholders or the Custodian against the Seller.

          It is understood and agreed that the representations and warranties
set forth in this Section 3.01 shall survive delivery of the respective Mortgage
Files to the Custodian on behalf of the Trustee.

the Seller, at any time at or prior to the Closing Date:

               (i)   if the Underwriting Agreement is terminated by the

been, since the time of execution of this Purchase Agreement or since the
respective dates as of which information is given in the Prospectus, any
material adverse change in the financial condition, earnings, business affairs
or business prospects of the Seller, whether or not arising in the ordinary
course of business, or

               (ii)  if there has occurred any material adverse change in the
financial markets in the United States, any outbreak of hostilities or
escalation thereof or other calamity or crisis or any change or development
involving a prospective change in national or international political, financial
or economic conditions, in each case the effect of which is such as to make it,
in the judgment of the Underwriters, impracticable to market the Class A

contracts for the sale of the Class A Certificates, Mezzanine Certificates and

               (v)   either (A) a change in control of the Seller shall have
occurred other than in connection with and as a result of the issuance and sale
by the Seller or registered, publicly offered common stock; or (B) the
Underwriters determine in their sole discretion that any material adverse change
has occurred in the management of the Seller,

               (vi)  there is (A) a material breach by the Seller of any
representation and warranty contained in this Purchase Agreement or the
Underwriting Agreement other than a representation or warranty relating to
particular Mortgage Loans, and the Underwriters have reason to believe in good
faith either that such breach is not curable within two (2) days or that such
breach may not have been cured in all material respects at the expiration of two
(2) days following discovery thereof by the Seller or (B) a failure by the
Seller to make any payment payable by it under this Purchase Agreement or (C)
any other failure by the Seller to observe and perform in any material respect
its material covenants, agreements and obligations with the Company, including
without limitation those contained in this Purchase Agreement, and the Company
has reason to believe in good faith that such failure may not have been cured in
all material respects at the expiration of two (2) days following discovery
thereof by the Seller, or

               (vii) the Seller fails to provide written notification to the
Underwriters of any change in its loan origination, acquisition or appraisal
guidelines or practices, or the Seller, without the prior consent of the
Underwriters (which shall not be unreasonably withheld), amends in any material
respect its loan origination, acquisition or appraisal guidelines or practices.

          It is the intention of the parties that (i) the Company is purchasing
on the Closing Date, and the Seller is selling on the Closing Date, the Initial
Mortgage Loans, rather than the Company providing to the Seller a loan secured
by the Initial Mortgage Loans on the Closing Date, and (ii) the Trustee is
purchasing on the Closing Date, and the Company is selling on the Closing Date,
the Initial Mortgage Loans, rather than the Trustee providing to the Company a
loan secured by the Initial Mortgage Loans, (iii) the Company will be purchasing
on each Subsequent Transfer Date, and the Seller will be selling on each
Subsequent Transfer Date, the

                                       32

<PAGE>

related Subsequent Mortgage Loans, rather than the Company providing to the
Seller a loan secured by the related Subsequent Mortgage Loans on each
Subsequent Transfer Date, and (iv) the Trustee will be purchasing on each
Subsequent Transfer Date, and the Company will be selling on each Subsequent
Transfer Date, the related Subsequent Mortgage Loans, rather than the Trustee
providing to the Company a loan secured by the related Subsequent Mortgage Loans
on each Subsequent Transfer Date. Accordingly, the parties hereto each intend to
treat these transactions as (i) a sale by the Seller, and a purchase by the
Company, of the Initial Mortgage Loans on the Closing Date, and (ii) a sale by
the Company, and a purchase by the Trustee, of the Initial Mortgage Loans on the
Closing Date, (iii) a sale by the Seller, and a purchase by the Company, of the
related Subsequent Mortgage Loans on each Subsequent Transfer Date, and (iv) a
sale by the Company, and a purchase by the Trustee, of the related Subsequent
Mortgage Loans on each Subsequent Transfer Date.

          Section 8.09 Successors and Assigns; Assignment of Purchase Agreement.
                       ---------------------------------------------------------

          This Purchase Agreement shall bind and inure to the benefit of and be
enforceable by the Seller, the Company, the Trustee, the Custodian, and their
respective successors and assigns. The obligations of the Seller under this
Purchase Agreement cannot be assigned or delegated to a third party without the
consent of the Company, which consent shall be at the Company's discretion. The
parties hereto acknowledge that (i) the Company is acquiring the Initial
Mortgage Loans for the purpose of selling them to the Trustee, who will hold the
Initial Mortgage Loans in trust for the benefit of the Certificateholders and
(ii) the Company is acquiring the Subsequent Mortgage Loans for the purpose of
selling them to the Trustee, who will hold the Subsequent Mortgage Loans for the
benefit of the Certificateholders. As an inducement to the Company and the
Trustee to purchase the Mortgage Loans, the Seller acknowledges and consents to
(i) the assignment by the Company to the Trustee of all of the Company's rights
or remedies against the Seller pursuant to this Purchase Agreement and to (ii)
the enforcement or exercise of any rights against the Seller pursuant to this
Purchase Agreement by the Company and the Trustee. Such enforcement of a right
or remedy by the Trustee, shall have the same force and effect as if the right
or remedy had been enforced or exercised by the Company directly.

          Section 8.10 Survival.
                       ---------

          The representations and warranties made herein by the Seller and the
provisions of Article V hereof shall survive the purchase of the Mortgage Loans
hereunder.

          Section 8.11 Liability of the Trustee.
                       -------------------------

          The Trustee is entering into the Basic Documents to which it is a
party solely as Trustee, hereunder and thereunder, and not in its individual
capacity, and all persons having any claim against the Trustee by reason of the
transactions contemplated by this Agreement or any other Basic Document shall
look only to the Trust Fund for payment or satisfaction thereof.

                     SELLER'S SUBSEQUENT TRANSFER INSTRUMENT

          Pursuant to this Seller's Subsequent Transfer Instrument (the

dated as of November 1, 2003 (the "Purchase Agreement"), among the Seller, the
Company, Wachovia Bank, National Association, as Custodian (the "Custodian") and
JPMorgan Chase Bank, as Trustee (the "Trustee"), the Seller and the Company
agree to the sale by the Seller and the purchase by the Company of the
subsequent Mortgage Loans listed on the attached Mortgage Loan Schedule (the
"Subsequent Mortgage Loans") and the related MI Policies.

          Capitalized terms used and not defined herein have their respective
meanings as set forth in the definitions contained in the Pooling and Servicing
Agreement, dated as of November 1, 2003 (the "Pooling and Servicing Agreement"),
between the Trustee, the Custodian, the Company and the Seller/Servicer which
definitions are incorporated by reference herein. All other capitalized terms

          (a) The Seller does hereby sell, transfer, assign, set over and convey
to the Company, without recourse, all of its right, title and interest in and to

principal and interest due on or before the Subsequent Cut-off Date and
collected after the Subsequent Cut-off Date shall belong to the Company pursuant
to the terms of this Seller's Instrument. The Seller, contemporaneously with the
delivery of this Seller's Instrument, has delivered or caused to be delivered to

Subsequent Mortgage Loans identified on the attached Mortgage Loan Schedule
shall be absolute and is intended by the Seller, the Company, the Custodian, the
Trustee and the Certificateholders to constitute and to be treated as a sale by
the Seller.

          The parties hereto intend that the transactions set forth herein
constitute a sale by the Seller to the Company on the Subsequent Transfer Date
of all the Seller's right, title and interest in and to the Subsequent Mortgage
Loans and the related MI Policies, and other property as and to the extent
described above. In the event the transactions set forth herein shall be deemed
not to be a sale, the Seller hereby grants to the Company as of the Subsequent
Transfer Date a security interest in all of the Seller's right, title and
interest in, to and under the Subsequent Mortgage Loans, and such other
property, to secure all of the Seller's obligations hereunder, and this Purchase
Agreement shall constitute a security agreement under applicable

law, and in such event, the parties hereto acknowledge that the Custodian, in
addition to holding the Subsequent Mortgage Loans and the related MI Policies on
behalf of the Trustee for the benefit of the Certificateholders, holds the
Subsequent Mortgage Loans and the related MI Policies as designee and agent of
the Company. The Seller agrees to take or cause to be taken such actions and to
execute such documents, including without limitation the filing of all necessary
UCC-1 financing statements filed in the State of Maryland (which shall be
submitted for filing as of the Subsequent Transfer Date), any continuation
statements with respect thereto and any amendments thereto required to reflect a
change in the name or corporate structure of the Seller or the filing of any
additional UCC-1 financing statements due to the change in the state of
incorporation of the Seller as are necessary to perfect and protect the
interests of the Company and its assignees in each Subsequent Mortgage Loan, the
related MI Policies and the proceeds thereof.

          (b)  The expenses and costs relating to the delivery of the Subsequent
Mortgage Loans, this Seller's Instrument and such other items required under the
Mortgage Loan Purchase Agreement shall be borne by the Seller.

          (c)  Additional terms of the sale are set forth on Attachment A

the Subsequent Mortgage Loans as of the date hereof. The Seller hereby confirms
that each of the conditions set forth in Section 2.02(b) of the Purchase
Agreement are satisfied as of the date hereof and further represents and
warrants that each Subsequent Mortgage Loan complies with the requirements of
this Seller's Instrument and Section 2.02(c) of the Purchase Agreement.

          (b)  The Seller is solvent, is able to pay its debts as they become
due and has capital sufficient to carry on its business and its obligations
hereunder; it will not be rendered insolvent by the execution and delivery of
this Seller's Instrument or by the performance of its obligations hereunder nor
is it aware of any pending insolvency; no petition of bankruptcy (or similar
insolvency proceeding) has been filed by or against the Seller prior to the date
hereof;

          (c)  All terms and conditions of the Purchase Agreement are hereby
ratified and confirmed; provided, however, that in the event of any conflict the
provisions of this Seller's Instrument shall control over the conflicting
provisions of the Purchase Agreement.

          Section 3. Recordation of the Seller's Instrument.
                     --------------------------------------

          To the extent permitted by applicable law, this Seller's Instrument,
or a memorandum thereof if permitted under applicable law, is subject to

of the counties or other comparable jurisdictions in which any or all of the
