(e) No Defenses. The Contract is not subject to any right of

dealer and purchased by the Originator, or originated by the Originator
directly, in the regular course of its business.

(h) Lawful Assignment. The Contract was not originated in and is not

the Contract pursuant to this Agreement or pursuant to transfers of Notes or
Certificates, or the ownership of the Contract by the Issuer, unlawful or render
the Contract unenforceable.

(i) Compliance with Law. At and since the date of origination of the
Contract, all requirements of any federal and state laws, rules and regulations
applicable to the Contract, including, without limitation, usury, truth in
lending, equal credit opportunity, predatory and abusive lending laws, have been

compliance with all such requirements. Such compliance is not affected by the
Purchaser's or its assignee's ownership of the Contract.

(j) Contract in Force. The obligation set forth in the Contract has
not been satisfied or subordinated in whole or in part, nor has the Contract
been rescinded, and the Manufactured Home securing the Contract has not been
released from the lien of the Contract in whole or in part.

(k) Valid Security Interest. Each Contract (other than the
Land-and-Home Contracts) creates a valid and enforceable perfected first
priority security interest in favor of the Originator in the Manufactured Home
covered thereby as security for payment of the Cut-off Date Principal Balance of
such Contract. The Originator has assigned to the Seller and the Seller has
assigned all of its right, title and interest in such Contract, including the
security interest in the Manufactured Home covered thereby, to the Purchaser.
The Purchaser will own each Contract free of any lien and has and will have a
valid and enforceable first priority security interest in each Manufactured Home
covered thereby. Upon execution of the Indenture, the Indenture Trustee will
have a valid and perfected first priority security interest in the related

Each Mortgage related to a Land-and-Home Contract is a valid first
lien in favor of the Seller on real property securing the amount owed by the
Obligor under the related Land-and-Home Contract subject only to (i) the lien of
current real property taxes and assessments, (ii) covenants, conditions and
restrictions, rights of way, easements and other matters of public record as of
the date of recording of such Mortgage, such exceptions appearing of record
being acceptable to mortgage lending institutions generally in the area wherein
the property subject to the Mortgage is located or specifically reflected in the
appraisal obtained in connection with the origination of the related
Land-and-Home Contract obtained by the Seller and (iii) 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 such Mortgage. As of the
Closing Date, with respect to each Contract, the Seller will have assigned all
of its right, title and interest in such Land-and-Home Contract and related
Mortgage, including the security interest in the Manufactured Home covered
thereby, to the Purchaser who will assign it to the Issuer, who will pledge it
to the Indenture Trustee under the Indenture. The Purchaser will have a valid
and perfected and enforceable first priority security interest each Mortgaged
Property related to a Land-and-Home Contract, subject to the exceptions set
forth above.

(l) Capacity of Parties. The signature(s) of the Obligor(s) on the
Contract are genuine and all parties to the Contract had full legal capacity to
execute the Contract.

(m) Good Title. In the case of a Contract purchased from a
manufactured housing dealer, the Originator purchased the Contract for fair
value and took possession thereof in the ordinary course of its business,
without knowledge that the Contract was subject to a security interest.
Immediately prior to the transfer hereunder, the Seller has good and marketable
title thereto free and clear of any encumbrance, equity, loan, pledge, charge,
claim or security interest and is the sole owner thereof with full right to
transfer the Contract to the Purchaser. With respect to any Contract bearing a
stamp indicating that such Contract has been sold to another party, such other
party's interest in such Contract has been released.

(n) No Defaults. As of the Cut-off Date, there was no default, breach,
violation or event permitting acceleration existing under the Contract and no
event which, with notice and the expiration of any grace or cure period, would
constitute such a default, breach, violation or event permitting acceleration
under such Contract (except payment delinquencies permitted by clause (b)
above). The Seller has not waived any such default, breach, violation or event
permitting acceleration except payment delinquencies permitted by clause (b)
above. As of the Closing Date, the related Manufactured Home is, to the best of
the Seller's and the Originator's knowledge, free of damage and in good repair.
No Manufactured Home has suffered damage that is not covered by a Hazard
Insurance Policy, including, but not limited to, hurricanes, earthquakes,
floods, tornadoes, straight-line winds, sinkholes, mudslides, volcanic eruptions
and other natural disasters.

(o) No Liens. As of the Closing Date, there are no liens or claims
which have been filed for work, labor or materials affecting the Manufactured
Home or any related Mortgaged Property securing the Contract which are or may be
liens prior to, or equal or coordinate with, the lien of the Contract.

(p) Equal Installments. Each Contract with a fixed Contract Rate
provides for level monthly payments which, if paid on each Due Date, amortize
the loan over its term.

(q) Enforceability. The Contract contains customary and enforceable
provisions so as to render the rights and remedies of the holder thereof
adequate for the realization against the collateral of the benefits of the
security provided thereby.

(r) One Original. There is only one original executed Contract (other
than the original executed copy retained by the Obligor), which Contract has
been delivered to the Purchaser or its custodian on or before the Closing Date.

(s) Loan-to-Value Ratio. At the time of their origination all of the
Contracts had Loan-to-Value Ratios not greater than 100%.

(t) Primary Resident. At the time of origination of the Contract the
Obligor was the primary resident of the related Manufactured Home. In the case
of the "Buy For" program, the Obligor has purchased the Manufactured Home for
the primary resident. The "Buy For" program loans represent 365 Contracts and
6.94% of the Cut-off Date Principal Balance of the Contracts as of the Cut-off
Date.

(u) Not Real Estate. With respect to each Contract other than a
Land-and-Home Contract, the related Manufactured Home is not generally
considered or classified as part of the real estate on which it is located under
the laws of the jurisdiction in which it is located.

(v) Notation of Security Interest. With respect to each Contract other
than a Land-and-Home Contract, if the related Manufactured Home is located in a
state in which notation of a security interest on the title document is required
or permitted to perfect such security interest, the title document shows, or if
a new or replacement title document with respect to such Manufactured Home is
being applied for such title document will be issued within 180 days and will
show, the Originator or its assignee as the holder of a first priority security
interest in such Manufactured Home; if the related Manufactured Home is located
in a state in which the filing of a financing statement under the UCC is
required to perfect a security interest in manufactured housing, such filings or
recordings have been duly made and show the Originator or its assignee as
secured party. If the related Manufactured Home secures a Land-and-Home
Contract, such Manufactured Home is subject to a Mortgage properly filed in the
appropriate public recording office or such Mortgage will be properly filed in
the appropriate public recording office within 180 days, naming the Originator
as mortgagee. In either case, the Indenture Trustee has the same rights as the
secured party of record would have (if such secured party were still the owner
of the Contract) against all Persons (including the Seller and any trustee in
bankruptcy of the Seller) claiming an interest in such Manufactured Home.

(w) Secondary Mortgage Market Enhancement Act. The related
Manufactured Home is a "manufactured home" within the meaning of ▇▇ ▇▇▇▇▇▇
▇▇▇▇▇▇ Code, Section 5402(6). Each manufactured housing dealer from whom the
Originator purchased such Contract, if any, was then approved by the Originator
in accordance with the requirements of the Secretary of Housing and Urban
Development set forth in 24 CFR Section 201.27. At the origination

of each Contract, the Originator was approved for insurance by the Secretary of
Housing and Urban Development pursuant to Section 2 of the National Housing Act.

no more than 4.45% of the Contracts are "simple interest" manufactured housing
installment loan agreements or manufactured housing installment sales contracts
and the remaining Contracts are actuarial manufactured housing installment loan
agreements or manufactured housing installment sales contracts.

(y) Land-and-Home Contracts. No Contract other than a Land-and-Home
Contract is secured, or intended to be secured, in whole or in part by the lien
of a mortgage or deed of trust creating a first lien on an estate in fee simple
in the real property.

(z) Financing of Real Property. No Contract other than a Land-and-Home
Contract has financed any amount in respect of real property.

(aa) Manufactured Homes. The related manufactured home is a
"manufactured home" within the meaning of Section 5402(6) of Title 42 of the
United States Code.

(bb) No Prepayment Penalties. No Contract contains any provisions
providing for the payment of a prepayment fee or penalty upon the prepayment of
a portion or all of the outstanding principal balance of that Contract.

(cc) No Predatory Loans. No Contract is covered by the Home Ownership
and Equity Protection Act of 1994 ("HOEPA") and no Contract is in violation of
any comparable state law. No Contract in the Trust Estate is a "high cost home,"
"covered," "high risk home" or "predatory" loan under HOEPA or any other
applicable state, federal or local law (or a similarly classified loan using
different terminology under a law imposing heightened regulatory scrutiny or
additional legal liability for residential mortgage loans having high interest
rates, points and/or fees), as applicable.

(dd) Georgia Loans. No Land-and-Home Contract was originated on or
after October 1, 2002 and before March 7, 2003, which is secured by property
located in the State of Georgia.

(ee) No Contract is a High Cost Loan or Covered Loan, as applicable
(as such terms are defined in Appendix E of the Standard & Poor's Glossary For
File Format For LEVELS(R) Version 5.6 Revised (attached hereto as Exhibit B).

Section 3.6 Representations and Warranties Regarding the Contract Files.

The Seller and the Originator each represents and warrants to the

(a) Bulk Transfer Laws. The transfer, assignment and conveyance of the
Contracts and the Asset Files by the Seller pursuant to this Agreement is not
subject to the bulk transfer or any similar statutory provisions in effect in
any applicable jurisdiction.

With respect to the representations and warranties set forth in this
Section that are made to the best of the each of the Seller's and Originator's
knowledge or as to which the Seller and the Originator have no knowledge, if it
is discovered by the Purchaser, the Seller, the Originator, the Servicer, the
Issuer or the Indenture Trustee that the substance of any such representation or
warranty is inaccurate and such inaccuracy materially and adversely affects the
value of the related Contract or the interest of the Trust Estate therein,
notwithstanding the Seller's or Originator's lack of knowledge with respect to
the substance of such representation and warranty being inaccurate at the time
the representation or warranty was made, such inaccuracy shall be deemed a
breach of the applicable representation or warranty and either the Seller or the
Originator, as applicable, shall cure such breach, repurchase the related
Contract at the Repurchase Price or substitute an Eligible Substitute Contract
therefor pursuant to Section 3.6(b).

Section 3.7 Remedies for Breach. (a)Upon discovery by the Originator or
Seller, as applicable, or upon notice from the Purchaser, the Issuer, the Owner
Trustee, the Servicer, the Originator, the Seller or the Indenture Trustee, as
applicable, of any materially defective document in, or that a document was not
transferred by the Seller (as listed on the Custodian's preliminary exception
report) as part of any File, or of a breach of any representation or warranty
set forth in Sections 3.1, 3.2, 3.3, 3.5 or 3.6 of this Agreement which
materially and adversely affects the interests of the Noteholders or the
Certificateholders, as applicable, in any Contract, the Originator or Seller, as
applicable, shall, within 60 days of its discovery or its receipt of notice of
such breach, deliver such missing document or cure such defect or breach in all
material respects or, in the event the Originator or Seller, as applicable,
cannot deliver such

missing document or cannot cure such defect or breach, the Originator or Seller,
as applicable, shall, within ninety (90) days of its discovery or receipt of
notice, either (i) repurchase the affected Contract at the Repurchase Price or
(ii) pursuant to the provisions of the Indenture, cause the removal of such
Contract from the Trust Estate and substitute one or more Eligible Substitute
Contracts. The Originator or Seller, as applicable, shall amend the List of
Contracts to reflect the withdrawal of such Contract from the terms of this
Agreement and the Indenture. Notwithstanding the foregoing, the failure of a
Contract File to include evidence of title to a Manufactured Home described in
the definition of "Contract File" on "Land and Home Contract File" shall not
constitute a breach until the passage of the 180-day period referred to in
Section 3.3(v), without the delivery of the required documents. The Originator
or Seller, as applicable, shall deliver to the Purchaser such amended List of
Contracts and shall deliver such other documents as are required by this
Agreement within five (5) days of any such amendment. Any repurchase pursuant to
this Section 3.7 shall be accomplished by transfer to an account designated by
the Purchaser of the amount of the Repurchase Price in accordance with the
Servicing Agreement. Any repurchase required by this Section 3.7 shall be made
in a manner consistent with Section 2.03 of the Servicing Agreement. The
Repurchase Price for any such Contract repurchased by the Originator or the
Seller, as applicable, shall be paid by the Originator or the Seller, as
applicable, to the Servicer for deposit in the Collection Account maintained by
it pursuant to Section 3.10 of the Servicing Agreement.

(b) The Originator, at its election, may substitute one or more
Eligible Substitute Contracts for any Contracts that it is obligated to
repurchase in accordance with this Section 3.6 (such Contracts being referred to
as the "Replaced Contracts") upon satisfaction of the following conditions:

(i) the Originator shall have conveyed to the Indenture Trustee
the Contracts to be substituted for the Replaced Contracts and the
Asset Files related to such Contracts and the Originator shall have
marked the Electronic Ledger indicating that such Contracts constitute
part of the Trust Estate;

(ii) the Contracts to be substituted for the Replaced Contracts
are Eligible Substitute Contracts and the Originator delivers an
Officers' Certificate, substantially in the form of Exhibit A hereto,
to the Indenture Trustee certifying that such Contracts are Eligible
Substitute Contracts;

(iii) the Seller shall have delivered to the Indenture Trustee
evidence of filing of a UCC-1 financing statement executed by the
Seller as debtor, naming the Indenture Trustee as secured party filed
in the State of Delaware, listing such Contracts as collateral, or
shall have delivered to the Depositor or the Indenture Trustee, as the
case may be, an amended List of Contracts;

(iv) in respect of Eligible Substitute Contracts that are Land
and Home Contracts, the Seller shall have delivered to the Depositor,
the related Land and Home Contract Files; and

(v) if the aggregate Principal Balance of such Replaced Contracts
is greater than the aggregate Principal Balance of the Contracts being
substituted,

the Originator shall have delivered to the Servicer for deposit in the
Collection Account the amount of such excess and shall have included
in the Officers' Certificate required by clause (ii) above a
certification that such deposit has been made.

Such substitution shall be effected prior to the first Determination
Date that occurs more than 90 days after the Originator becomes aware, or
receives written notice from the Indenture Trustee, of the breach referred to in
this Section 3.7. Promptly after any substitution of a Contract, the Originator
shall give written notice of such substitution to each Rating Agency.

(c) It is understood and agreed that the obligations of the Originator
and the Seller set forth in this Section 3.7 to cure or repurchase a defective
Contract shall, except to the extent provided in last sentence of this Section
3.7(c) and in Section 5.1 of this Agreement, constitute the sole remedies of the
Purchaser, the Issuer, the Certificateholders (or the Owner Trustee on behalf of
the Certificateholders) and the Noteholders (or the Indenture Trustee, or the
Servicer, acting pursuant to the Servicing Agreement, on behalf of the
Noteholders) against the Originator or the Seller, as applicable, respecting a
missing document or a breach of the representations and warranties contained in
Sections 3.1, 3.2, 3.3, 3.5 or 3.6 of this Agreement. It is understood and
agreed that the representations and warranties set forth in Sections 3.1, 3.2,
3.3, 3.5 or 3.6 of this Agreement shall survive delivery of the respective Asset
Files to the Issuer. In addition, the Originator shall defend and indemnify the
Purchaser, the Issuer, the Owner Trustee, the Indenture Trustee, its officers,
directors, employees and agents, and the Noteholders and the Certificateholders
against all costs, expenses, losses, damages, claims and liabilities, including
reasonable fees and expenses of counsel, arising out of any claims which may be
asserted against or incurred by any of them as a result of any third-party
action arising out of the breach of the representations and warranties set forth
in Sections 3.3 (i), 3.3 (bb) and 3.3 (cc) of this Agreement.

survive the purchase of the Contracts hereunder.

Section 7.11 Third Party Beneficiary. The Indenture Trustee shall be deemed
a third-party beneficiary of this Agreement to the same extent as if it were a
party hereto, and shall have the right to enforce the provisions of this

Standard & Poor's has categorized loans governed by anti-predatory lending laws
in the Jurisdictions listed below into three categories based upon a combination
of factors that include (a) the risk exposure associated with the assignee
liability and (b) the tests and thresholds set forth in those laws. Note that
certain loans classified by the relevant statute as Covered are included in
Standard & Poor's High Cost Loan Category because they included thresholds and
tests that are typical of what is generally considered High Cost by the
industry.
