 (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 an 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”): 
  
 (i) the original Mortgage Note endorsed to “JPMorgan Chase Bank, National Association, as Trustee of
the NovaStar Mortgage Funding Trust, Series 2005-4, relating to the NovaStar Home Equity Loan Asset-Backed Certificates, Series 2005-4”; 
  

 2 

 (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, National Association, as Trustee of the NovaStar Mortgage Funding Trust, Series 2005-4, relating to the NovaStar Home Equity Loan Asset-Backed
Certificates, Series 2005-4,” 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 

 Promptly after the Closing Date in the case of an 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 (iii) 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 an 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
2005-4” (or its equivalent) in the field “Pool” which identifies the series of the Certificates issued in connection with such Mortgage Loans. The Custodian will certify in its final certification that the MERS System shows the
Trustee on behalf of the Certificateholders as the beneficial owner of the Mortgage Loans registered on the MERS System. 
  
 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 
  

 4 

 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 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.

 Upon discovery by the Seller or upon notice from the Company, the Trustee, or the Custodian, as
applicable, of a breach of any representation or warranty in this subsection (b) with respect to any Mortgage Loan or upon the occurrence of a Repurchase Event, which materially and adversely affects the value of the related Mortgage Loan or

 In the event that the Seller elects to substitute an Eligible Substitute
Mortgage Loan or Loans for a Deleted Mortgage Loan pursuant to this Section 3.01, the Seller shall deliver to the Custodian on behalf of the Trustee, with respect to such Eligible Substitute Mortgage Loan or Loans, the original Mortgage Note
and all other documents and agreements as are required by Section 2.01 hereof, with the Mortgage Note endorsed as required by such Section 2.01 hereof. No substitution will be made in any calendar month after the Determination Date for
such month. Monthly Payments due with respect to Eligible Substitute Mortgage Loans in the month of substitution shall not be part of the Trust Fund and will be retained by the Servicer and remitted by the Servicer to the Seller on the next
succeeding Payment Date. For the month of substitution, distributions to the Payment Account pursuant to the Pooling and Servicing Agreement will include the Monthly Payment due on a Deleted Mortgage Loan for such month and thereafter the Seller
shall be entitled to retain all amounts received in respect of such Deleted Mortgage Loan. The Servicer shall amend or cause to be amended the Mortgage Loan Schedule to reflect the removal of such Deleted Mortgage Loan and the substitution of the
Eligible Substitute Mortgage Loan or Loans and the Servicer shall deliver the amended Mortgage Loan Schedule to the Custodian and the Trustee. Upon such substitution, the Eligible Substitute Mortgage Loan or Loans shall be subject to the terms of
this Purchase Agreement and the Pooling and Servicing Agreement in all respects, the Seller shall be deemed to have made the representations and warranties with respect to the Eligible Substitute Mortgage Loan contained 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 (i) the Repurchase Price that would otherwise apply to such Deleted Mortgage Loan, exceeds (ii) the principal balance of the related Eligible Substitute Mortgage Loan (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. 
  

 26 

 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.

 Section 8.08 Intention of the Parties. 
  
 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 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 
  

 34 

 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.

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.

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.

 To the extent permitted by applicable law, this Seller’s Instrument, or a memorandum thereof if permitted under
applicable law, is subject to recordation in all appropriate public offices for real property records in all of the counties or other comparable jurisdictions in which any or all of the properties subject to the Mortgages are situated, and in any
other appropriate public recording office or elsewhere, such recordation to be effected by the Servicer, but only when accompanied by an Opinion of Counsel to the effect that such recordation materially and beneficially affects the interests of the

 This Seller’s Instrument shall be construed in accordance with the laws of the State of New York and the obligations,

 Exhibit 10.2 
  
 Execution Copy 
  
 ISDA® 
  
 International Swaps and Derivatives Association, Inc. 
  
 NOVATION AGREEMENT 
  
 dated as of December 15, 2005 among: 
  
 THE ROYAL BANK OF SCOTLAND PLC. (the “Remaining Party”), 
 NOVASTAR FINANCIAL, INC. (the
“Transferor”) 
  
 AND 
  
 NOVASTAR MORTGAGE SUPPLEMENTAL INTEREST TRUST, SERIES 2005-4 (the
“Transferee”). 
  
 The Transferor and the Remaining Party have
entered into one or more Transactions (each an “Old Transaction”), each evidenced by a Confirmation (an “Old Confirmation”) with reference numbers D6817771, D6825448, D6825458, D6830294, D6830295, D6846132,
D6853798, D6853799, D6855787 and D6859939, respectively, attached hereto as Exhibit I and subject to a 1992 ISDA Master Agreement dated as of June 30, 2005 (the “Old Agreement”). 
  
 The Transferor and the Remaining Party novated a $35,000,000 notional amount (the
“Previously Novated Portion”) from the Old Transaction with the reference number D6817771 (the “Partially Novated Transaction”) pursuant to a Novation Agreement dated as of October 14, 2005, among the
Transferor, the Remaining Party and NovaStar Mortgage Supplemental Interest Trust, Series 2005-3. 
  
 The Remaining Party and the Transferee are simultaneously entering into a 1992 ISDA Master Agreement dated as of the date hereof in the form attached hereto as Exhibit II (the “New Agreement”).

  
 With effect from and including December 15, 2005 (the “Novation
Date”) the Transferor wishes to transfer by novation to the Transferee, and the Transferee wishes to accept the transfer by novation of, all the rights, liabilities, duties and obligations of the Transferor under and in respect of each Old
Transaction, excluding the Previously Novated Portion of the Partially Novated Transaction (each a “Novated Transaction”), with the exception of the Excluded Rights and Obligations referred to below, with the effect that the
Remaining Party and the Transferee enter into a new transaction (each a “New Transaction”) between them having terms identical to those of each Novated Transaction, subject to the same exceptions and as more particularly described
below. 
  
 The Remaining Party wishes to accept
the Transferee as its sole counterparty with respect to the New Transactions. 
  
 The Transferor and the Remaining Party wish to have released and discharged, as a result and to the extent of the transfer described above, their respective obligations under and in respect of the Novated Transactions. 
  
 Accordingly, the parties agree as follows: —

  

	1.	Definitions. 

  
 Terms defined in the ISDA Master Agreement (Multicurrency-Cross Border) as published in 1992 by the International Swaps and Derivatives Association, Inc. (the “1992 ISDA Master Agreement”) are used
herein as so 

 defined, unless otherwise provided herein. For purposes of this Novation Agreement, “Excluded Rights and
Obligations” means all obligations of each of the Transferor and the Remaining Party to Transfer (as defined in the Credit Support Annex to the Old Agreement) Eligible Collateral (as so defined) in respect of the Novated Transactions and
all related rights of the Remaining Party and the Transferor under the Old Agreement. 
  

	2.	Transfer, Release, Discharge and Undertakings. 

  
 Subject to the execution and delivery of the New Agreement by each of the parties thereto to the other, with effect from and including the Novation Date and in
consideration of the mutual representations, warranties and covenants contained in this Novation Agreement and other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged by each of the parties): 

 

	 	(a)	subject to Section 2(d) of this Novation Agreement, the Remaining Party and the Transferor are each released and discharged from further obligations to each other with respect
to each Novated Transaction and their respective rights against each other thereunder are cancelled, provided that such release and discharge shall not affect any rights, liabilities or obligations of the Remaining Party or the Transferor with
respect to payments or other obligations due and payable or due to be performed prior to the Novation Date, and all such payments and obligations shall be paid or performed by the Remaining Party or the Transferor in accordance with the terms of the
Novated Transactions; 

  

	 	(b)	in respect of each New Transaction, the Remaining Party and the Transferee each undertake liabilities and obligations towards the other and acquire rights against each other
identical in their terms to each corresponding Novated Transaction (and, for the avoidance of doubt, as if the Transferee were the Transferor and with the Remaining Party remaining the Remaining Party, save for the Excluded Rights and Obligations
and any other rights, liabilities or obligations of the Remaining Party or the Transferor with respect to payments or other obligations due and payable or due to be performed prior to the Novation Date); 

  

	 	(c)	each New Transaction shall be governed by, form part of, and be subject to the New Agreement and the relevant Old Confirmation (which, in conjunction and as deemed modified to be
consistent with this Novation Agreement, shall be deemed to be a Confirmation between the Remaining Party and the Transferee), and the offices of the Remaining Party and the Transferee for purposes of each New Transaction shall be their offices at
their addresses for notices provided for in the New Agreement; and 

  

	 	(d)	on the Novation Date, the Remaining Party shall transfer all of the Posted Collateral (as defined in the Credit Support Annex to the Old Agreement) held by it in respect of the
Novated Transactions to the account or accounts of the Transferor identified by it by notice given to the Remaining Party as provided in the Old Agreement, and the Transferor shall transfer all Posted Collateral held by it in respect of the Novated
Transactions to the account or accounts of the Remaining Party identified by it by notice given to the Transferor as provided in the Old Agreement, in each case together with all Interest Amount and Distributions thereon (as so defined). The
Remaining Party’s or the Transferor’s failure to effect these transfers will continue to constitute Potential Events of Default and may constitute Events of Default under the Old Agreement notwithstanding the transfer by novation
contemplated herein. 

  

	3.	Representations and Warranties. 

  

	 	(a)	On the date of this Novation Agreement: 

  

	 	(i)	Each of the parties makes to each of the other parties those representations and warranties set forth in Section 3(a) of the 1992 ISDA Master Agreement with references in such
