Mortgaged Property is located and specifically referred to in the lender's title

to the originator of such Mortgage Loan, and (3) such other matters to which
like properties are commonly subject which do not, individually or in the
aggregate, materially interfere with the benefits of the security intended to be
provided by the Mortgage. Any security agreement, chattel mortgage or equivalent
document related to, and delivered to the Trustee in connection with, a Mortgage

right to sell and assign the same to the Trustee;

any such representation, warranty or assumption of liability relative to any
related Mortgaged Property. In addition, no representations or warranties are
made by the Seller with respect to the absence or effect of fraud in the
origination of any Assigned Mortgage Loan.

     The Seller hereby agrees that any cure of a breach of such representations
and warranties shall be in accordance with the terms of the Pooling and
Servicing Agreement.

     4. Representations and Warranties as to the BANA Mortgage Loans. The Seller
hereby represents and warrants to the Purchaser with respect to the BANA
Mortgage Loans or each BANA Mortgage Loan, as the case may be, as of the date
hereof or such other date set forth herein that as of the Closing Date:

          (a) The information set forth in the mortgage loan schedule attached
hereto as Exhibit V (the "BANA Mortgage Loan Schedule") is true and correct in
all material respects;

          (b) There are no delinquent taxes, ground rents, governmental
assessments, insurance premiums, leasehold payments, including assessments
payable in future installments or other outstanding charges, affecting the lien
priority of the related Mortgaged Property (a "BANA Mortgaged Property");

          (c) The terms of the BANA Mortgage Notes and the related Mortgages
(each, a "BANA 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 BANA
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, the title insurer, to the extent required
by the related policy, and is reflected on the BANA Mortgage Loan Schedule. No
instrument of waiver, alteration or modification has been executed, and no
mortgagor of a BANA Mortgage Loan (a "BANA Mortgagor") has been released, in
whole or in part, except in connection with an assumption agreement approved by
the insurer under the Primary Mortgage Insurance Policy, if any, the title
insurer, to the extent required by the policy, and which assumption agreement
has been delivered to the Trustee;

          (d) The BANA Mortgage Notes and the BANA Mortgages are not subject to
any right of rescission, set-off, counterclaim or defense, including the defense
of usury, nor will


                                       7



the operation of any of the terms of the BANA Mortgage Notes and the BANA
Mortgages, or the exercise of any right thereunder, render either the BANA
Mortgage Notes or the BANA Mortgages 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;

          (e) All buildings upon each BANA Mortgaged Property are insured by an
insurer generally acceptable to prudent mortgage lending institutions against
loss by fire, hazards of extended coverage and such other hazards as are
customary in the area the related BANA Mortgaged Property is located, pursuant
to insurance policies conforming to the requirements of Customary Servicing
Procedures and the Pooling and Servicing Agreement. All such insurance policies
contain a standard mortgagee clause naming the originator of the BANA Mortgage
Loan, its successors and assigns as mortgagee and all premiums thereon have been
paid. If the BANA 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 or FHLMC. The BANA 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
BANA Mortgage to maintain such insurance at mortgagor's cost and expense and to
seek reimbursement therefor from the mortgagor;

          (f) Any and all requirements of any federal, state or local law
including, without limitation, usury, truth in lending, real estate settlement
procedures, consumer credit protections, all applicable predatory and abusive
lending laws, equal credit opportunity or disclosure laws applicable to the
origination and servicing of BANA Mortgage Loans have been complied with;

          (g) No BANA Mortgage has been satisfied, canceled, subordinated or
rescinded, in whole or in part (other than as to Principal Prepayments in full
which may have been received prior to the Closing Date), and no BANA Mortgaged
Property has been released from the lien of the related BANA Mortgage, in whole
or in part, nor has any instrument been executed that would effect any such
satisfaction, cancellation, subordination, rescission or release;

          (h) The BANA Mortgage is a valid, existing and enforceable first lien
on the BANA Mortgaged Property, including all improvements on the BANA 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 acceptable to mortgage lending institutions generally and
specifically referred to in the lender's title insurance policy delivered to the
originator of the BANA Mortgage Loan and which do not adversely affect the
Appraised Value of the BANA Mortgaged Property, (C) if the BANA Mortgaged
Property consists of Cooperative Stock, any lien for amounts due to the
cooperative housing corporation for unpaid assessments or charges or any lien of
any assignment of rents or maintenance expenses secured by the real property
owned by the cooperative housing corporation, and (D) other matters to which
like


                                       8



properties are commonly subject which do not materially interfere with the
benefits of the security intended to be provided by the BANA Mortgage or the
use, enjoyment, value or marketability of the related BANA Mortgaged Property.
Any security agreement, chattel mortgage or equivalent document related to and
delivered in connection with the BANA Mortgage Loan establishes and creates a
valid, existing and enforceable first lien and first priority security interest
on the property described therein and the Seller has the full right to sell and
assign the same to the Purchaser;

          (i) The BANA Mortgage Note and the related BANA Mortgage are genuine
and each is the legal, valid and binding obligation of the maker thereof,
enforceable in accordance with its terms except as enforceability may be limited
by (A) bankruptcy, insolvency, liquidation, receivership, moratorium,
reorganization or other similar laws affecting the enforcement of the rights of
creditors and (B) general principles of equity, whether enforcement is sought in
a proceeding in equity or at law;

          (j) All parties to the BANA Mortgage Note and the BANA Mortgage had
legal capacity to enter into the BANA Mortgage Loan and to execute and deliver
the BANA Mortgage Note and the BANA Mortgage, and the BANA Mortgage Note and the
BANA Mortgage have been duly and properly executed by such parties;

          (k) The proceeds of the BANA Mortgage Loan have been fully disbursed
to or for the account of the related BANA Mortgagor and there is no obligation
for the mortgagee to advance additional funds thereunder and any and all
requirements as to completion of any on-site or off-site improvements and as to
disbursements of any escrow funds therefor have been complied with. All costs,
fees and expenses incurred in making or closing the BANA Mortgage Loan and the
recording of the BANA Mortgage have been paid, and the Mortgagor is not entitled
to any refund of any amounts paid or due to the mortgagee pursuant to the BANA
Mortgage Note or BANA Mortgage;

          (l) To the best of the Seller's knowledge, all parties which have had
any interest in the BANA Mortgage Loan, whether as mortgagee, assignee, pledgee
or otherwise, are (or, during the period in which they held and disposed of such
interest, were) in compliance with any and all applicable "doing business" and
licensing requirements of the laws of the state wherein the BANA Mortgaged
Property is located;

          (m) Either (A) the BANA Mortgage Loan is covered by an ALTA lender's
title insurance policy, acceptable to FNMA or FHLMC, issued by a title insurer
acceptable to FNMA or FHLMC and qualified to do business in the jurisdiction
where the BANA Mortgaged Property is located, insuring (subject to the
exceptions contained in (h)(A), (B), (C) and (D) above) the Seller, its
successors and assigns as to the first priority lien of the BANA Mortgage in the
original principal amount of the BANA Mortgage Loan, (B) a title search has been
done showing no lien (other than the exceptions contained in (h)(A), (B), (C)
and (D) above) on the BANA Mortgaged Property senior to the lien of the BANA
Mortgage or (C) in the case of any BANA Mortgage Loan secured by a BANA
Mortgaged Property located in a jurisdiction where such policies are generally
not available, an opinion of counsel of the type customarily rendered in such
jurisdiction in lieu of title insurance is instead received. For each BANA
Mortgage Loan covered by a title insurance policy (x) the Seller is the sole
insured of such lender's title


                                       9



insurance policy, and such lender's title insurance policy is in full force and
effect and will be in full force and effect upon the consummation of the
transactions contemplated by this Agreement and (y) no claims have been made
under such lender's title insurance policy, and the Seller has not done, by act
or omission, anything which would impair the coverage of such lender's title
insurance policy;

          (n) There is no default, breach, violation or event of acceleration
existing under the BANA Mortgage or the BANA Mortgage Note and 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,
and the Seller has not waived any default, breach, violation or event of
acceleration;

          (o) As of the date of origination of the BANA Mortgage Loan, there
were no mechanics' or similar liens or claims filed for work, labor or material

          (p) All improvements which were considered in determining the

than sixty days after the proceeds of the BANA Mortgaged Loan were disbursed.
The BANA Mortgage Loans are fixed-rate mortgage loans having an original term to
maturity of not more than 30 years, with interest payable in arrears on the
first day of the month. Each BANA Mortgage Note requires a monthly payment which
is sufficient to fully amortize the original principal balance over the original
term thereof and to pay interest at the related Mortgage Interest Rate. No BANA
Mortgage Note permits negative amortization;

          (s) There is no proceeding pending or, to the Seller's knowledge,
threatened for the total or partial condemnation of the BANA Mortgaged Property
and such property is in good repair and is undamaged by waste, fire, earthquake

adversely the value of the BANA Mortgaged Property as security for the BANA
Mortgage Loan or the use for which the premises were intended;

          (t) The BANA Mortgage and related BANA Mortgage Note contain customary
and enforceable provisions such as to render the rights and remedies of the
holder thereof adequate for the realization against the BANA Mortgaged Property
of the benefits of the security provided thereby, including (A) in the case of a

best of the Seller's knowledge, following the date of origination of the BANA
Mortgage Loan, the related BANA Mortgaged Property has not been subject to any
bankruptcy proceeding or foreclosure proceeding and the related BANA Mortgagor
has not filed for protection under applicable bankruptcy laws. There is no
homestead or other exemption or right available to the BANA Mortgagor or any
other person which would interfere with the right to sell the BANA Mortgaged
Property at a trustee's sale or the right to foreclose the BANA Mortgage;

          (u) With respect to the BANA Mortgage Loans, other than any Borrowers

Mac and satisfied this requirements of Title XI of FIRREA;

          (x) In the event the BANA Mortgage constitutes a deed of trust, a

designated and currently so serves, and no fees or expenses are or will become
payable by the Trustee to the trustee under the deed of trust, except in
connection with a trustee's sale after default by the Mortgagor;

          (y) No BANA Mortgage Loan is a graduated payment mortgage loan, no
BANA Mortgage Loan has a shared appreciation or other contingent interest
feature, and no BANA Mortgage Loan contains any "buydown" provision;

          (z) The BANA Mortgagor has received all disclosure materials required
by applicable law with respect to the making of mortgage loans of the same type
as the BANA Mortgage Loan and rescission materials required by applicable law if
the BANA Mortgage Loan is a refinanced mortgage loan, i.e., the proceeds of such
BANA Mortgage Loan were not used to purchase the related Mortgaged Property;

          (aa) Each Primary Mortgage Insurance Policy to which any BANA Mortgage
Loan is subject will be issued by an insurer acceptable to FNMA or FHLMC, which
insures that portion of the BANA Mortgage Loan in excess of the portion of the
Appraised Value of the BANA Mortgaged Property required by FNMA or FHLMC. All
provisions of such Primary Mortgage Insurance Policy have been and are being
complied with, such policy is in full force and effect, and all premiums due
thereunder have been paid. Any BANA Mortgage subject to any such Primary
Mortgage Insurance Policy obligates the Mortgagor thereunder to maintain such
insurance and to pay all premiums and charges in connection therewith at least
until Loan-to-Value Ratio of such BANA Mortgage Loan is reduced to less than
80%. The Mortgage Interest Rate for the BANA Mortgage Loan does not include any
such insurance premium;

lawfully occupied under applicable law, (B) all inspections, licenses and
certificates required to be made or issued with respect to all occupied portions
of the BANA Mortgaged Property and, with respect to the use and occupancy of the

obtained from the appropriate authorities and (C) no improvement located on or
part of the BANA Mortgaged Property is in violation of any zoning law or

          (cc) With respect to each BANA Mortgage Loan, the related Assignment

recording under the laws of the jurisdiction in which the related BANA Mortgaged
Property is located;

          (dd) All payments required to be made prior to the Cut-off Date for
such BANA Mortgage Loan under the terms of the BANA Mortgage Note have been made

related Mortgage is recorded in the name of MERS, immediately prior to the
transfer and assignment contemplated herein, the Seller was the sole owner of
record and holder of the BANA Mortgage Loan. With respect to the BANA Mortgage
Loans, the BANA Mortgage Loans were not assigned or pledged by the Seller and
the Seller had good and marketable title thereto, and the Seller had full right
to transfer and sell the BANA Mortgage Loans to the Trustee free and clear of
any encumbrance, participation interest, lien, equity, pledge, claim or security
interest and had full right and authority subject to no interest or
participation in, or agreement with any other party to sell or otherwise
transfer the BANA Mortgage Loans;

          (gg) With respect to the BANA Mortgage Loans, any future advances made
prior to the Cut-off Date have been consolidated with the outstanding principal
amount secured by the BANA Mortgage, and the secured principal amount, as
consolidated, bears a single interest rate and single repayment term. With
respect to each BANA Mortgage Loan, the lien of the related BANA Mortgage
securing the consolidated principal amount is expressly insured as having first
lien priority by a title insurance policy, an endorsement to the policy insuring
the mortgagee's consolidated interest or by other title evidence acceptable to
FNMA and FHLMC. The consolidated principal amount does not exceed the original
principal amount of the BANA Mortgage Loan;

          (hh) The BANA Mortgage Loan was underwritten in accordance with the
applicable underwriting guidelines in effect at the time of origination with
exceptions thereto exercised in a reasonable manner;


                                       12



          (ii) If the BANA Mortgage Loan is secured by a long-term residential
lease, (1) the lessor under the lease holds a fee simple interest in the land;
(2) the terms of such lease expressly permit the mortgaging of the leasehold
estate, the assignment of the lease without the lessor's consent and the

BANA Mortgage with substantially similar protections; (3) the terms of such
lease do not (a) allow the termination thereof upon the lessee's default without

opportunity to cure, such default, (b) allow the termination of the lease in the
event of damage or destruction as long as the BANA Mortgage is in existence, (c)

     Notwithstanding the foregoing, no representations or warranties are made by
the Seller as to the environmental condition of any BANA Mortgaged Property; the
absence, presence or effect of hazardous wastes or hazardous substances on any
BANA Mortgaged Property; any casualty resulting from the presence or effect of
hazardous wastes or hazardous substances on, near or emanating from any BANA
Mortgaged Property; the impact on Certificateholders of any environmental
condition or presence of any hazardous substance on or near any BANA Mortgaged
Property; or the compliance of any BANA Mortgaged Property with any
environmental laws, nor is any agent, Person or entity otherwise affiliated with
the Seller authorized or able to make any such representation, warranty or
assumption of liability relative to any BANA Mortgaged Property. In addition, no
representations or warranties are made by the Seller with respect to the absence
or effect of fraud in the origination of any BANA Mortgage Loan.

     It is understood and agreed that the representations and warranties set
forth in this Section shall survive delivery of the respective BANA Mortgage
Files to the Trustee or the Custodian and shall inure to the benefit of the
Trustee, notwithstanding any restrictive or qualified endorsement or assignment.

     5. No Broker's Fees. The Seller hereby represents and warrants to the
Purchaser that the Seller has not dealt with any broker, investment banker,
agent or other Person (other than the Purchaser and Banc of America Securities
LLC) who may be entitled to any commission or compensation in connection with
the sale of the Mortgage Loans.

     6. Repurchase or Substitution. Upon discovery by the Seller, the Purchaser,
the Trustee or any assignee, transferee or designee of the Trustee of a missing
or defective document in the Mortgage File, as provided in Section 2 of this
Agreement or the Pooling and Servicing Agreement or a breach of any of the
representations and warranties set forth in Section 3 and Section 4 (to the
extent provided therein) that materially and adversely affects the value of any
Mortgage Loan or the interest therein of the Purchaser or the Purchaser's
assignee, the party discovering such breach shall give prompt written notice to
the others. Within 90 days after the earlier of the Seller's discovery or
receipt of notification of such missing or defective document or breach of a
representation and warranty (notwithstanding the Seller's lack of knowledge with
respect to the substance of such representation and warranty), the Seller shall
promptly cure such breach in all material respects, or in the event such missing
or defective document or breach cannot be cured, the Seller shall repurchase the
affected Mortgage Loan. Alternatively, the Seller hereby agrees (notwithstanding
the Seller's lack of knowledge with respect to the substance of such
representation and warranty), if so requested by the Purchaser, to substitute
for any such Mortgage Loan, a new mortgage loan having characteristics such that
the representations and warranties referred to in Section 3 (to the extent
provided therein) or Section 4, as applicable, above would not have been
incorrect (except for representations and warranties as to the correctness of
the related Mortgage Loan Schedule) had such substitute mortgage loan originally
been a Mortgage Loan. The Seller further agrees that a substituted mortgage loan
will have on the date of substitution the criteria set forth in the definition
of "Substitute Mortgage Loan" in the Pooling and Servicing Agreement and will
comply with the substitution provisions of Section 2.02 of the Pooling and
Servicing Agreement. The Seller shall remit to the Purchaser, in cash, the
difference between the unpaid principal balance of the Mortgage Loan to be
substituted and the unpaid principal balance of the substitute mortgage loan.

          If the breach of the representation set forth in clauses (k) and (o)
of Section 3 herein or in clauses (f) and (oo) of Section 4 herein occurs as a
result of a violation of an applicable predatory or abusive lending law, the
Seller agrees to reimburse the Purchaser for all costs and damages incurred by
the Purchaser as a result of the violation of such law; provided that, with
respect to any Assigned Mortgage Loan, the Seller has no obligation to reimburse
the Purchaser for any such costs and damages that are reimbursed by a Servicer.

          The Purchaser acknowledges and agrees that it shall have no rights
against the Seller under this Section 6, except with respect to the preceding
paragraph, if the breach of any representation or warranty also constitutes a
breach of a representation or warranty made by a Servicer under the related
Transfer Agreement, but shall instead enforce its rights against such Servicer.

          (a) The Seller hereby agrees to furnish any and all information,

cancelled pursuant to the terms of the related Mortgage Note together with
accrued interest at the Mortgage Interest Rate minus the Servicing Fee Rate to
the date of cancellation (the "Total Covered Amount") upon the accidental death
of the related Mortgagor. Any Monthly Covered Amount payable by the Seller
pursuant to this Section 7(c) shall be deposited by the Seller in the applicable
Servicer Custodial Account on or prior to, in the case of the Monthly Covered
Amount, the Remittance Date relating to the Distribution Date immediately
following the Due Date as to which such Monthly Covered Amount relates and, in
the case of a Total Covered Amount, the Remittance Date relating to the

Securities Administrator, on behalf of the Trust, against the Seller.

     11. Recharacterization. The parties to this Agreement intend the conveyance
by the Seller to the Purchaser of all of its right, title and interest in and to
the Mortgage Loans and all Mortgage Files, including all interest and principal

of law provisions. Neither this Agreement nor any term hereof may be changed,

adverse effect on Holders of Certificates without the prior written consent of
the Trustee. The Trustee shall be protected in consenting to any such change to
the same extent provided in Article IX of the Pooling and Servicing Agreement.
This Agreement may be signed in any number of counterparts, each of which shall
be deemed an original, which taken together shall constitute one and the same
instrument. This Agreement shall bind and inure to the benefit of and be

assigns.
