(a)           Title and Mortgage Loan Schedule. RRAC represents and warrants to, and agrees with, Sequoia that (i) on the Closing Date, RRAC will have good, valid and marketable title to the mortgage loans identified on Schedule A hereto (the “Mortgage Loans”), in each case free and clear of all liens, mortgages, deeds of trust, pledges, security interests, charges, encumbrances or other claims; (ii) upon transfer to Sequoia, Sequoia will receive good, valid and marketable title to all of the Mortgage Loans, in each case free and clear of any liens, mortgages, deeds of trust, pledges, security interests, charges, encumbrances or other claims; and (iii) as of the date on which RRAC purchased such Mortgage Loan from [List Originators] (each, an “Originator”), the information set forth in the Mortgage Loan Schedule in the fields identified as “Document Type,” “Monthly Income” and “Assets Verified” is complete, true and correct in all material respects.

(b)           Additional Representations. RRAC represents and warrants to, and agrees with, Sequoia that, as of the Closing Date:

(i)            As to each Mortgage Loan, the lien of the Mortgage is free and clear of all adverse claims, liens and encumbrances having priority over the first lien of the Mortgage subject only to (1) the lien of non-delinquent current real property taxes and assessments not yet due and payable, (2) covenants, conditions and restrictions, rights of way, easements and other matters of the public record as of the date of recording which are acceptable to mortgage lending institutions generally and which do not adversely affect the appraised value of the Mortgaged Property as set forth in such appraisal and (3) other matters to which like properties are commonly subject which do not materially interfere with the benefits of the security intended to be provided by the Mortgage or the use, enjoyment, value or marketability of the related Mortgaged Property.

(ii)           To the actual knowledge of RRAC, each Mortgage Loan constitutes a “qualified mortgage” under Section 860G(a)(3)(A) of the Code and Treasury Regulation Section 1.860-2(a)(1).

(iii)          As of the Closing Date, the most recent FICO score listed on the Mortgage Loan Schedule was no more than four months old.

(iv)          As to each Mortgage Loan transferred to RRAC pursuant to [       ], no Mortgage Loan is subject to a lost note affidavit.

(v)           As to each Mortgage Loan, with respect to any hazard or mortgage insurance covering such a Mortgage Loan and the related Mortgaged Property, the Originator has not engaged in, and RRAC has no knowledge of the Mortgagor’s having engaged in any act or omission that would impair the coverage of any such policy, the benefits of the endorsement, or the validity and binding effect of either, including without limitation, no unlawful fee, commission, kickback, or other unlawful compensation or value of any kind as has been or will be received, retained or realized by any attorney, firm or other person or entity, and no such unlawful items have been received, retained or realized by the Originator.

(vi)          As to each Mortgage Loan subject to the Flow Mortgage Loan Sale and Servicing Agreement dated as of [ ], between RRAC and [Originator Name], as amended by the Assignment, Assumption and Recognition Agreement dated [      ] among RRAC, Sequoia, the Trustee and [Originator Name] (the “[Originator Name] Agreement”), no fraud or material error, omission, misrepresentation, negligence or similar occurrence with respect to a Mortgage Loan has taken place on the part of the Originator, any correspondent or mortgage broker involved in the origination of such Mortgage Loan, the Mortgagor, or any appraiser or other party involved in the origination of the Mortgage Loan or in the application of any insurance in relation to such Mortgage Loan.

(A)          The terms of the Lease expressly permit the mortgaging of the leasehold estate, the assignment of the Lease without the lessor’s consent (or the lessor’s consent has been obtained and is in the Mortgage File), and the acquisition by the holder of the Mortgage of the rights of the lessee upon foreclosure or assignment in lieu of foreclosure or provide the holder of the Mortgage with substantially similar protection.

(B)          The terms of the Lease do not allow the termination thereof upon the lessee’s default without the holder of the Mortgage being entitled to receive written notice, and opportunity to cure, such default or prohibit the holder of the Mortgage from being insured under the hazard insurance policy related to the Mortgaged Property.

(C)          The original term of the Lease is not less than 15 years and the Lease does not terminate by its terms prior to at least five years from the maturity date of the Mortgage Loan.

In the event of a breach of any of the representations and warranties of an Originator under any of the Purchase Agreements specified on Schedule B hereto that materially and adversely affects the value of a Mortgage Loan or the interest therein of the Certificateholders (as assignees of Sequoia), if the applicable Originator is unable to cure, repurchase or substitute the related Mortgage Loan or make an indemnification payment with respect thereto pursuant to the terms of the applicable Purchase Agreement because such Originator is the subject of a Bankruptcy or insolvency proceeding or no longer in existence, then RRAC will cure the breach or repurchase or substitute such Mortgage Loan, or make an indemnification payment with respect thereto, pursuant to Section 2.04 of the Pooling and Servicing Agreement and Section 3 below.

Section 3.   Arbitration and Representations and Warranties of RRAC with respect to the Period of Time Since Each Originator Sold Mortgage Loans.

(a)           RRAC hereby covenants and agrees that, if a breach of any representation and warranty set forth in Purchase Agreements with respect to the characteristics of a Mortgage Loan exists on the date hereof that materially and adversely affects the value of any Mortgage Loan or the interest of Sequoia in any Mortgage Loan and such breach did not exist as of the date that RRAC purchased such Mortgage Loan, RRAC shall have a period of 60 days from the earlier of either discovery or receipt of written notice from Sequoia to RRAC of such breach within which to correct or cure such breach. Each determination as to whether there has been such a breach shall be conducted on a Mortgage Loan-by-Mortgage Loan basis. RRAC hereby covenants and agrees that if any breach cannot be corrected or cured within such 60 day period, then, at RRAC’s option, RRAC shall (i) repurchase the related Mortgage Loan at the Repurchase Price, (ii) substitute a mortgage loan for the defective Mortgage Loan in accordance with the applicable Purchase Agreement or (iii) make an indemnification payment in an amount equal to the reduction in value of such Mortgage Loan as a result of such breach not later than 90 days after its discovery or receipt of notice of such breach and in the case of (i) or (iii) above, by wire transfer of immediately available funds to such account as Sequoia shall specify to RRAC.

(b)           RRAC and Sequoia agree that if any controversy or claim arising out of or relating to an obligation or alleged obligation of RRAC to repurchase a Mortgage Loan or Mortgage Loans pursuant to Section 2(d) or Section 3(a) is not resolved by the end of the 180 day period commencing on the date that RRAC receives a repurchase request, such controversy or claim shall be resolved, at Sequoia’s discretion, by either mediation or third-party arbitration, and RRAC shall agree to the selected resolution method. In addition, if Sequoia or the Trustee as Sequoia’s assignee does not elect to refer the matter to mediation or third-party arbitration, any Certificateholder may do so by notice to Sequoia within ninety (90) days of the filing date of the Report on Form 10-D reporting that the dispute has not been resolved within such 180 day period.

(c)           To commence third-party arbitration or mediation, Sequoia or a Certificateholder shall deliver written notice to RRAC of its election. If the notice states that Sequoia or the Certificateholder elects arbitration, within ten (10) Business Days after the date of receipt by RRAC of such notice, each party may submit the names of one or more proposed Arbitrators to the other party in writing. If the parties have not agreed on the selection of an Arbitrator within five (5) Business Days after the first such submission, then the party commencing arbitration shall, within the next five (5) Business Days, notify the American Arbitration Association in New York, New York and request that it appoint a single Arbitrator with experience in arbitrating disputes arising in the financial services industry.

5

(d)           It is the intention of the parties that any arbitration shall be conducted in as efficient and cost-effective a manner as is reasonably practicable, without the burden of discovery. Accordingly, the Arbitrator will resolve the dispute on the basis of a review of the written correspondence between the parties (including any supporting materials attached to such correspondence) conveyed by the parties to each other in connection with the dispute prior to the delivery of notice to commence arbitration; however, upon a showing of good cause, a party may request the Arbitrator to direct the production of such additional information, evidence and/or documentation from the parties that the Arbitrator deems appropriate. If requested by the Arbitrator or any party, any hearing with respect to an arbitration shall be conducted by video conference or teleconference, except upon the agreement of both parties or the request of the Arbitrator.

(e)           If any such dispute is referred to arbitration, the Arbitrator shall determine the allocation of any expenses, which may include allocation of expenses to any Certificateholder that referred the dispute to arbitration. If the matter is referred to mediation, the parties to the mediation shall mutually determine the allocation of any expenses.

(f)            The following capitalized terms shall have the meaning specified below:

Arbitrator: A person who is not affiliated with RRAC, Sequoia or any Originator, who is a member of the American Arbitration Association.

Repurchase Price: With respect to any Mortgage Loan, a price equal to (i) the unpaid principal balance of such Mortgage Loan plus (ii) interest on such unpaid principal balance at the mortgage interest rate from and including the last Due Date through which interest has been paid by or on behalf of the Mortgagor up to the Due Date following the date of repurchase, minus (iii) amounts received in respect of such repurchased Mortgage Loan which are being held in the Collection Account for distribution in connection with such Mortgage Loan.

Section 4.    Conveyance of Mortgage Loans.

(a)           Mortgage Loans.  In return for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, RRAC, concurrently with the execution and delivery hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to Sequoia, without recourse, all of RRAC’s right, title and interest in and to the Mortgage Loans, including the related Mortgage Documents and all principal and interest received by RRAC on or with respect to the Mortgage Loans after [date] (the “Cut-off Date”) (other than Scheduled Payments due on or before such date), and all such payments due after such date but received on or prior to such date and intended by the related Mortgagors to be applied after such date, all insurance policies with respect to the Mortgage Loans, and all proceeds of the foregoing.

(b)           Limited Remedies. Sequoia acknowledges and agrees that it shall have no recourse to RRAC with respect to any Defective Mortgage Loan except as provided in Section 2(d) and Section 3 and that Sequoia’s remedies with respect to any other Defective Mortgage Loans shall be exercised with respect to the Originator of such Defective Mortgage Loan as set forth in the applicable Purchase Agreement.

Section 5.    Intention of Parties.  The conveyance of the Mortgage Loans and all other property hereunder by RRAC as contemplated hereby is absolute and is intended by the parties to constitute a sale of the Mortgage Loans and such other property by RRAC to Sequoia. It is, further, not intended that such conveyance be the grant of a security interest to secure a loan or other obligation. However, in the event that, notwithstanding the intent of the parties, the Mortgage Loans and the other property described in Section 4(a) are held to be the property of RRAC, or if for any other reason this Agreement is held or deemed to create a security interest in the Mortgage Loans and such other property, then this Agreement shall constitute a security agreement, and the conveyance provided for in Section 4(a) shall be deemed to be a grant by RRAC to Sequoia of, and RRAC hereby grants to Sequoia, to secure all of RRAC’s obligations hereunder, a security interest in all of RRAC’s right, title and interest, whether now owned or hereafter acquired, in and to (i) the Mortgage Loans, including the Mortgage Notes, the Mortgages, and the right to all payments of principal and interest received on or with respect to the Mortgage Loans after the Cut-off Date (other than Scheduled Payments due on or before such date), and all such payments due after such date but received on or prior to such date and intended by the related Mortgagors to be applied after such date, (ii) all of RRAC’s right, title and interest, if any, in and to all amounts from time to time credited to and the proceeds of any Custodial Accounts or any Escrow Account established with respect to the Mortgage Loans, (iii) with respect to the Mortgage Loans, to the extent set forth in the applicable Purchase Agreement, the [Originator Name] Agreement or the Flow Mortgage Loan Servicing Agreement, dated [date], between RRAC and [Servicer Name], as amended on [date] and as further amended by the Assignment, Assumption and Recognition Agreement, dated [ ], by and among RRAC, Sequoia, the Trustee and [Servicer Name] (the “[Servicer Name] Agreement”), RRAC’s rights and obligations under the applicable Purchase Agreement, the [Originator Name] Agreement or the [Servicer] Agreement, (iv) all of RRAC’s right, title and interest, if any, in REO Property and the proceeds thereof, (v) all of RRAC’s rights under any Insurance Policies related to the Mortgage Loans, (vi) RRAC’s security interest in any collateral pledged to secure the Mortgage Loans, including the Mortgaged Properties, and (vii) all proceeds of the conversion, voluntary or involuntary, of any of the foregoing into cash or other liquid assets, including, without limitation, all Insurance Proceeds, Liquidation Proceeds and condemnation awards.

7

RRAC and Sequoia shall, to the extent consistent with this Agreement, take such actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement.  RRAC shall arrange for filing any Uniform Commercial Code financing statements and continuation statements in connection with such security interest.
