Interest Distribution

Amount: On each distribution date, to the extent of the available distribution amount, each class of certificates will, subject to the limitations described herein, be entitled to receive accrued and unpaid interest determined on the basis of the outstanding Class Principal Amount (or class notional amount, in the case of the Class A-IO Certificates) of such class immediately prior to such distribution date, the applicable certificate interest rate and the related accrual period.

SEMT 2010-H1 APRIL 21, 2010

Net Interest Shortfall: With respect to any distribution date, the “Net Interest Shortfall” is equal to the sum of:

(1)    Any net prepayment interest shortfalls for that distribution date; and

(2)    the amount of interest which would otherwise have been received with respect to any mortgage loan that was subject to a reduction in the amount of monthly interest payment on a mortgage loan pursuant to the Servicemembers Civil Relief Act Relief Act or similar state or local law (any such reduction, a “Relief Act Reduction”) .   Net Interest Shortfalls for any distribution date will be allocated among all classes of Senior Certificates and all classes of Subordinate Certificates proportionately based on current interest otherwise distributable on each class on such distribution date.

Unpaid Interest: Any unpaid interest accrued on a class of certificates will be carried forward and added to the amount which holders of such certificates will be entitled to receive on the next distribution date.  Any unpaid interest amount so carried forward will not bear interest.

Senior Principal

Distribution Amount: On each distribution date, the available distribution amount remaining after payment of interest with respect to the Senior Certificates, up to the amount of the Senior Principal Distribution Amount for such distribution date, will be distributed as principal of the Senior Certificates (other than the Class A-IO Certificates) as described above and will equal the sum of:

(1)    the product of (a) the Senior Percentage and (b) the principal portion of the scheduled payment due on each mortgage loan on the related due period, whether or not received;

(2)    the product of (a) the Senior Prepayment Percentage and (b) each of the following amounts: (i) the principal portion of each full and partial principal prepayment made by a borrower on a mortgage loan during the related prepayment period; (ii) each other unscheduled collection, including subsequent recoveries, insurance proceeds and net liquidation proceeds (other than with respect to any mortgage loan that was finally liquidated during the related prepayment period) representing or allocable to recoveries of principal of the related mortgage loans received during the related prepayment period; and (iii) the principal portion of the purchase price of each mortgage loan purchased by the originator or seller due to a material breach of a representation and warranty with respect to such mortgage loan or, in the case of a permitted substitution of a defective mortgage loan, the amount representing any principal adjustment in connection with any such replaced mortgage loan included in the available distribution amount for such distribution date; and (iv) the principal portion of the purchase price for mortgage loans that are at least 90 days delinquent that the Controlling Holder may elect to purchase and the principal portion of the purchase price for the mortgage loans paid by the party exercising its rights to terminate the trust fund;

(3)    with respect to each mortgage loan which became a liquidated mortgage loan during the related prepayment period, the lesser of (a) the net liquidation proceeds allocable to principal and (b) the product of (i) the Senior Prepayment Percentage for that distribution date and (ii) the remaining principal balance of the mortgage loan at the time of liquidation; and

(4)    any amounts described in clauses (1) through (3) above that remain unpaid with respect to the Senior Certificates from prior distribution dates.   If on any distribution date the allocation to the Senior Certificates then entitled to distributions of principal of related full and partial principal prepayments and other amounts in the percentage required above would reduce the sum of the Class Principal Amounts of the Senior Certificates below zero, the distribution to the class or classes of Senior Certificates of the related Senior Prepayment Percentage of those amounts for that distribution date will be limited to the percentage necessary to reduce the related Class Principal Amounts to zero.   In addition, if on any distribution date the aggregate of the Class Principal Amounts of the Subordinate Certificates was reduced to less than or equal to 0.75% of the Stated Principal Balance of the mortgage loans as of the closing date, the Senior Principal Distribution Amount for the next succeeding distribution date will include all principal collections on the mortgage loans distributable on such succeeding distribution date, and the Subordinate Principal Distribution Amount will be zero, until the aggregate of the Class Principal Amounts of the Senior Certificates (other than the Class A-IO Certificates) is reduced to zero.

Subordinate Principal Distribution Amount:   Distributions of principal with respect to the Subordinate Certificates will be made on each distribution date sequentially to the Subordinate Certificates in order of their numerical class designations, beginning with the Class B-1 Certificates, until each such class has received its pro rata share of the Subordinate Principal Distribution Amount for that distribution date. Distributions to each such class’ share of the aggregate Subordinate Principal Distribution Amount will be made only after payments of interest and principal to each class ranking senior to such class, and interest to such class, have been paid.   The “Subordinate Principal Distribution Amount” for each distribution date is equal to the sum of:

(1)    the product of (a) the Subordinate Percentage and (b) the principal portion of each scheduled payment on each mortgage loan due during the related due period, whether or not received;

(2)    the product of (a) the related Subordinate Prepayment Percentage and (b) each of the following amounts: (i) the principal portion of each full and partial principal prepayment made by a borrower on a mortgage loan during the related prepayment period, (ii) each other unscheduled collection, including subsequent recoveries, Insurance proceeds and net liquidation proceeds (other than with respect to any mortgage loan that was finally liquidated during the related prepayment period), representing or allocable to recoveries of principal of mortgage loans received during the related prepayment period; and  (iii) the principal portion of the purchase price of each mortgage loan that was purchased by the originator or seller due to a material breach of a representation and warranty with respect to such mortgage loan or, in the case of a permitted substitution of a defective mortgage loan, the amount representing any principal adjustment in connection with any such replaced mortgage loan included in the available distribution amount for such distribution date; and (iv) the principal portion of the purchase price for mortgage loans that are at least 90 days delinquent that the Controlling Holder may elect to purchase and the principal portion of the purchase price for mortgage loans paid by a party exercising its rights to terminate the trust fund;

(3)    with respect to unscheduled recoveries allocable to principal of any mortgage loan that was finally liquidated during the related prepayment period, the related net liquidation proceeds allocable to principal, to the extent not distributed pursuant to clause (3) of the definition of Senior Principal Distribution Amount); and

(4)    any amounts described in clauses (1) through (3) for any previous distribution date that remain unpaid.   Notwithstanding the above, with respect to each class of Subordinate Certificates other than the Class B-1 Certificates, if on any distribution date the Class Principal Amount of that class and the aggregate of the Class Principal Amounts of all classes of subordinate certificates which have a lower payment priority than that class was reduced to less than or equal to 0.75% of the Stated Principal Balance of the mortgage loans as of the closing date, the portion of the Subordinate Principal Distribution Amount otherwise distributable to such class or classes on the next succeeding distribution date will, on such succeeding distribution date, be allocated among the subordinate certificates with a higher payment priority, pro rata, based on their respective Class Principal Amounts.
If on any distribution date the aggregate of the Class Principal Amounts of the subordinate certificates was reduced to less than or equal to 0.75% of the Stated Principal Balance of the mortgage loans as of the closing date, the Senior Principal Distribution Amount for the next succeeding distribution date will include all principal collections on the mortgage loans distributable on such succeeding distribution date, and the Subordinate Principal Distribution Amount will be zero, until the aggregate of the Class Principal Amounts of the Senior Certificates is reduced to zero.

Losses: If a Realized Loss occurs on the mortgage loans (including a servicing modification resulting in a reduction of the outstanding principal amount of such mortgage loan or a principal forbearance), then, on each distribution date, the principal portion of that Realized Loss will be allocated first, to reduce the Class Principal Amount of each class of Subordinate Certificates, in inverse order of priority, until the Class Principal Amount thereof has been reduced to zero (that is, such Realized Losses will be allocated to the Class B-4 Certificates while those certificates are outstanding, then to the Class B-3 Certificates while those certificates are still outstanding, and so forth) and second, to the Senior Certificates (other than the Class A-IO Certificates). In determining whether a Realized Loss is a loss of principal or of interest, liquidation proceeds and other recoveries on a mortgage loan will be applied first to outstanding expenses incurred with respect to such mortgage loan, then to accrued, unpaid interest, and finally to principal.

The Class Principal Amount of the lowest ranking class of certificates then outstanding will also be reduced by the Certificate Writedown Amount.

Any class of certificates whose Class Principal Amount has been reduced to zero due to the allocation of Realized Losses will nonetheless remain outstanding under the pooling agreement and will continue to be entitled to receive subsequent recoveries until the termination of the trust fund, but will have no voting rights

Sponsor’s Risk Retention: The sponsor (or affiliates of the sponsor) will initially retain the following certificates: (i) all of the Non-Offered Certificates, representing 6.50% of the original principal balance of the securitization, and (ii) 5% of the original principal balance of Offered Certificates.  Following the Closing Date, the sponsor (or affiliates of the sponsor) will continue to retain these certificates until such time as regulations governing sponsor risk retention (or “skin-in-the-game”) have been finalized and become effective.  Once regulations have become effective, the sponsor (and its affiliates) may sell or transfer any portion of these retained certificates that is in excess of what is then required to be retained under applicable regulations.

Dispute Resolution: In the event there is a dispute arising from an unresolved repurchase request for a potential violation of any representation or warranty made at the time of closing by the Originator, the Originator and the Seller have agreed to submit to binding arbitration by a non-affiliated third party to resolve the dispute.

Clean-up Call: The terms of the transaction allow the Servicer to purchase all of the mortgage loans from the trust fund, thereby causing an early retirement of the certificates on any distribution date on which the aggregate principal balance of the mortgage loans is less than 10% of the aggregate principal balance of the mortgage loans as of the Cut-off Date.  If the Servicer does not exercise the clean-up call, an affiliate of the Sponsor may purchase all of the mortgage loans from the trust fund, thereby causing an early retirement of the certificates on any distribution date on which the aggregate principal balance of the mortgage loans is less than 5% of the aggregate principal balance of the mortgage loans as of the Cut-off Date.

Registration: The Offered Certificates will be issued in book-entry form through DTC.

Federal Tax Treatment: The Offered Certificates will represent ownership of regular interests in a REMIC.  The Class R Certificate will be designated as the sole class of residual interest in the REMIC.

ERISA Eligibility: The Offered Certificates are expected to be eligible for purchase by employee benefit plans and other retirement plans and arrangements subject to Title I of ERISA and Section 4975 of the Code. Prospective investors should review with their legal advisors whether the purchase and holding of any of the Offered Certificates could give rise to a transaction prohibited or not otherwise permissible under ERISA or other similar laws.

SMMEA Treatment: The Offered Certificates are expected to constitute “mortgage related securities” for purposes of SMMEA, so long as they are rated in one of the two highest rating categories by at least one rating agency.
