Buyer will subject to the terms and conditions of this Agreement purchase additional Trust Interests.

After the Initial Purchase Date, as part of a Purchase Price Increase Request, Sellers may request and Buyer will fund, subject to the terms and conditions of this Agreement, an increase in the Purchase Price for the Transactions in respect of the Trust Interests based upon the acquisition of additional REO Properties by the REO Subsidiary or a Trust Subsidiary, or additional Trust Mortgage Loans by a Trust Subsidiary, as applicable.  From time to time, the Sellers will pay a Mandatory Partial Prepayment to Buyer in accordance with Section 4(b) hereof.

d.              Provided that no Default shall have occurred and be continuing, and Buyer has received the applicable Mandatory Partial Prepayment, Buyer agrees to permit the release from the REO Subsidiary or a Trust Subsidiary, as applicable, of the related REO Property or the release from a Trust Subsidiary of the related Trust Mortgage Loans, as applicable, attributable to such Mandatory Partial Prepayment (including, the Repurchase Assets related thereto) at the request of Sellers.  The applicable REO Property, Trust Mortgage Loans and the Repurchase Assets related thereto, shall be delivered to the applicable Seller or the designee of such Seller free and clear of any lien, encumbrance or claim of Buyer, any Trust Subsidiary or REO Subsidiary.

e.               With respect to a Liquidated Asset, Sellers agree to (i) provide Buyer with a copy of a report from the related Servicer indicating that such Purchased Mortgage Loan, Trust Mortgage Loan or REO Property has been liquidated, (ii) cause the applicable Servicer to (x) if such Liquidated Asset is a Purchased Mortgage Loan, remit to the Servicer Account, immediately upon the applicable Servicer’s receipt of the proceeds, the Repurchase Price, with respect to such Liquidated Asset and thereafter cause the applicable Servicer to remit such proceeds to the Collection Account within two (2) Business Days and (y) if such Liquidated Asset is a REO Property or Trust Mortgage Loan, remit the Mandatory Partial Prepayment in accordance with Section 4(b) and (iii) provide Buyer a notice specifying each Purchased Mortgage Loan, Trust Mortgage Loan or REO Property that has been liquidated.  Buyer agrees to release its ownership interest in such Liquidated Asset or, if the Liquidated Asset is a REO Property or Trust Mortgage Loan, permit the release of the Liquidated Asset from the REO Subsidiary or a Trust Subsidiary, as applicable, concurrently with receipt of confirmation that proceeds have been received by the applicable Servicer.  All amounts on deposit in the REO Account and each Trust Account shall be remitted to the Collection Account on each Payment Date in accordance with the terms of the applicable Trust Agreement.

f.                 Promptly upon a Purchased Mortgage Loan or Trust Mortgage Loan becoming a REO Property as contemplated by Section 8(b), (a) Sellers shall (i)

25

notify Buyer in writing that such Purchased Mortgage Loan or Trust Mortgage Loan has become a REO Property and the value attributed to such REO Property by Sellers, (ii) deliver to Buyer and Custodian an Asset Schedule with respect to such REO Property, (iii) be deemed to make the representations and warranties listed on Schedule 1-B hereto with respect to such REO Property; and (iv) without limiting the requirements set forth in the definition of Market Value, deliver to Buyer a true and complete copy of a BPO of such REO Property no less frequently than once per 180 day period, and (b) solely with respect to a Purchased Mortgage Loan becoming a REO Property (i) such REO Property shall automatically and immediately be deemed contributed by PennyMac Corp.  to REO Subsidiary or a Trust Subsidiary, as applicable, or by PennyMac Holdings to a Trust Subsidiary, as applicable, and (ii) such REO Property shall be deemed a REO Property owned by the REO Subsidiary or a Trust Subsidiary, as applicable, hereunder and its Market Value as determined by Buyer shall be included in the Market Value of the Trust Interests.  The acquisition of such REO Property by the REO Subsidiary or any Trust Subsidiary shall result in an increase in the value of the Trust Interests (as determined in accordance with the definition of Market Value) of the REO Subsidiary or a Trust Subsidiary, as applicable, and any Purchase Price Increase or Margin Deficit attributed to any change in Category shall be paid by the Buyer or Sellers as applicable.

g.              The acquisition of Trust Mortgage Loans by any Trust Subsidiary shall result in an increase in the value of the Trust Interests (as determined in accordance with the definition of Market Value) of the applicable Trust Subsidiary.  For the avoidance of doubt, to the extent that a Trust Mortgage Loan owned by a Trust Subsidiary is converted to an REO Property, a Purchase Price Increase shall be deemed to occur and shall be offset against the Purchase Price for the related Trust Mortgage Loan, which shall be deemed reduced.

5.              Price Differential.

a.               On each Business Day that a Transaction is outstanding, the Pricing Rate shall be reset and, unless otherwise agreed, the accrued and unpaid Price Differential shall be settled in cash on each related Payment Date.  One (1) Business Day prior to the Payment Date, Buyer shall give Sellers written or electronic notice of the amount of the Price Differential due on such Payment Date.  On the Payment Date, Sellers shall pay to Buyer the Price Differential for such Payment Date (along with any other amounts to be paid pursuant to Sections 7 and 34 hereof), by wire transfer in immediately available funds.

b.              If Sellers fail to pay all or part of the Price Differential by 4:00 p.m. (New York City time) on the related Payment Date, with respect to any Purchased Asset, Sellers shall be obligated to pay to Buyer (in addition to, and together with, the amount of such Price Differential) interest on the unpaid Repurchase Price at a rate per annum equal to the Post Default Rate until the Price Differential is received in full by Buyer.

26

▇.     ▇▇▇▇▇▇▇ may remit to Buyer funds in an amount up to the outstanding Purchase Price (including, without duplication, Purchase Price Increase) of the Purchased Assets, to be held as unsegregated cash margin and collateral for all Obligations under this Agreement (such amount, to the extent not applied to Obligations under this Agreement, the “Buydown Amount”).  The Buydown Amount shall be used by Buyer in order to calculate the aggregate Price Differential, which will accrue on the aggregate Purchase Price then outstanding minus the Buydown Amount, applied to Transactions involving the lowest Pricing Rate.  The Sellers shall be entitled to request a drawdown of the Buydown Amount or remit additional funds to be added to the Buydown Amount no more than one time per week.  Without limiting the generality of the foregoing, in the event that a Margin Call or other Default exists, the Buyer shall be entitled to use any or all of the Buydown Amount to cure such circumstance or otherwise exercise remedies available to the Buyer without prior notice to, or consent from, any Seller.  Within two (2) Business Days’ receipt of written request from any Seller, and provided no Margin Call or other Default exists, Buyer shall remit any portion of such Buydown Amount back to such Seller.

6.     Margin Maintenance

a.     If at any time the Market Value of any Purchased Mortgage Loan, Trust Mortgage Loan or REO Property subject to a Transaction is less than Buyer’s Margin Amount for such Purchased Mortgage Loan, Trust Mortgage Loan or REO Property (a “Margin Deficit”), then Buyer may by notice to Sellers require Sellers to transfer to Buyer cash in an amount at least equal to the Margin Deficit subject to or related to a Transaction or solely with the consent of Buyer in its sole discretion, additional Mortgage Loans or REO Property with a Purchase Price equal to such Margin Deficit (such requirement, a “Margin Call”).

b.     Notice delivered pursuant to Section 6(a) may be given by any written or electronic means.  With respect to a Margin Call in the amount of less than 5% of the Purchase Price for all Transactions (a “Low Percentage Margin Call”), any notice given before 5:00 p.m. (New York City time) on a Business Day shall be met, and the related Margin Call satisfied, no later than 5:00 p.m. (New York City time) on the following Business Day; notice given after 5:00 p.m. (New York City time) on a Business Day shall be met, and the related Margin Call satisfied, no later than 5:00 p.m. (New York City time) on the second Business Day following the date of such notice. With respect to all Margin Calls other than Low Percentage Margin Calls, any notice given before 10:00 a.m. (New York City time) on a Business Day shall be met, and the related Margin Call satisfied, no later than 5:00 p.m. (New York City time) on such Business Day; notice given after 10:00 a.m. (New York City time) on a Business Day shall be met, and the related Margin Call satisfied, no later than 5:00 p.m. (New York City time) on the following Business Day. The foregoing time requirements for satisfaction of a Margin Call are referred to as the “Margin Deadlines”).  The failure of Buyer, on any one or more occasions, to exercise its rights hereunder, shall not change or alter the terms and conditions to which this Agreement is subject or limit the right

27

of Buyer to do so at a later date.  Sellers and Buyer each agree that a failure or delay by Buyer to exercise its rights hereunder shall not limit or waive Buyer’s rights under this Agreement or otherwise existing by law or in any way create additional rights for Sellers.

c.     In the event that a Margin Deficit exists with respect to any Purchased Mortgage Loan, Trust Mortgage Loan or REO Property, Buyer may retain any funds received by it to which the Sellers, any Trust Subsidiary or REO Subsidiary, as applicable, would otherwise be entitled hereunder, which funds (i) shall be held by Buyer against the related Margin Deficit and (ii) may be applied by Buyer against the Repurchase Price of any Purchased Mortgage Loan or, without duplication, Release Price of any REO Property or Trust Mortgage Loan, as applicable, for which the related Margin Deficit remains otherwise unsatisfied.  Notwithstanding the foregoing, the Buyer retains the right, in its sole discretion, to make a Margin Call in accordance with the provisions of this Section 6.

d.     In the event that Sellers reasonably believe that the Market Value of all Purchased Assets exceeds the aggregate Buyer’s Margin Amount of all Purchased Assets by more than $3,000,000, Sellers may request that Buyer remit additional Purchase Price with respect to specific Purchased Assets to be identified by Sellers to Buyer, and Buyer will consider such request; provided that Buyer will make such determination in its sole discretion. Any additional Purchase Price remitted by Buyer to Sellers hereunder (and in the case of REO Properties and Trust Mortgage Loans, Purchase Price Increase) shall be added to the Purchase Price for the applicable Purchased Assets. For the avoidance of doubt, Buyer shall have no obligation to advance additional Purchase Price hereunder, and Buyer’s agreement to do so in any instance, shall not be deemed as Buyer’s agreement to do so in the future.

7.     Income Payments

a.     All Income received on account of the Purchased Mortgage Loans or Trust Certificates (including Income derived from REO Properties owned by REO Subsidiary and any Trust Subsidiary, and Trust Mortgage Loans owned by any Trust Subsidiary) during the term of a Transaction shall be the property of Buyer.  Sellers shall and shall cause the applicable Servicer to deposit (i) all Income with respect to Purchased Mortgage Loans into the Collection Account within two (2) Business Days following receipt by either Seller or the applicable Servicer, (ii) all REO Subsidiary Income into the REO Account within two (2) Business Days following receipt by REO Subsidiary or a Servicer, as applicable, and (iii) all Trust Income of a Trust Subsidiary into the related Trust Account within two (2) Business Days following receipt by such Trust Subsidiary or the applicable Servicer; provided, however, that notwithstanding the foregoing, (a) the applicable Servicer shall be entitled to retain Ancillary Income to which it is entitled under the applicable Servicing Agreement, (b) Specialized Loan Servicing LLC shall be entitled to retain funds on account of uncollected servicing fees and unreimbursed servicing advances as permitted pursuant to the

28

applicable Servicing Agreement with respect to SWDNSI Trust Series 2010-3 and SWDNSI Trust Series 2010-4 and (c) the applicable Servicer shall remit payments to the Trustees pursuant to the Master Trust Agreement with respect to SWDNSI Trust Series 2010-3 and SWDNSI Trust Series 2010-4, in each case without any obligation to deposit such Income into the Collection Account, REO Account or a Trust Account.

b.     On each Payment Date, Buyer shall, or shall direct the Bank to remit amounts on deposit in the Collection Account, each Trust Account or REO Account as follows:

(1)   first, to Buyer in payment of any accrued and unpaid Price Differential, to the extent not paid by Sellers to Buyer pursuant to Section 5;

(2)   second, to Buyer in reduction of the Repurchase Price or Release Price of any Liquidated Asset, an amount equal to the lesser of (x)  Liquidation Proceeds received on or with respect to such Liquidated Asset or (y) Repurchase Price or Release Price of such Liquidated Asset;

(3)   third, without limiting the rights of Buyer under Section 6 of this Agreement, to Buyer, in the amount of any unpaid Margin Deficit;

(4)   fourth, to the payment of all other costs and fees payable to Buyer pursuant to this Agreement;

(5)   fifth, only to the extent of amounts then remaining on deposit in the Collection Account, to the payment of reasonable and actual fees and unreimbursed advances of the applicable Servicer attributable to the Purchased Mortgage Loans, Trust Mortgage Loans or REO Properties, as applicable; and

(6)   sixth, to Sellers, any remaining amounts.

c.     Notwithstanding any provision to the contrary in this Section 7, upon the occurrence and continuance of an Event of Default or on the Termination Date all Income shall be remitted to Buyer for application to the aggregate Repurchase Price and any other amounts owing by Sellers hereunder as Buyer deems appropriate.

30

REO Property to REO Subsidiary or a Trust Subsidiary, as applicable, by deed within the period of time generally necessary in the applicable jurisdiction for the applicable Servicer.

c.     Trust Interests as Securities.  The parties acknowledge and agree that the Trust Interests shall constitute and remain “securities” as defined in Section 8-102 of the Uniform Commercial Code; each Seller covenants and agrees that (i) the Trust Interests are not and will not be dealt in or traded on securities exchanges or securities markets and (ii) the Trust Interests are not and will not be investment company securities within the meaning of Section 8-103 of the Uniform Commercial Code.  Each Seller shall, at its sole cost and expense, take all steps as may be necessary in connection with the endorsement, transfer, delivery and pledge of all Trust Interests to Buyer.

d.     Additional Interests.  If Sellers shall, as a result of their ownership of the Trust Interests, become entitled to receive or shall receive any certificate evidencing any trust interest or other equity interest, any option rights, or any equity interest in REO Subsidiary or any Trust Subsidiary, whether in addition to, in substitution for, as a conversion of, or in exchange for the Trust Interests, or otherwise in respect thereof, such Seller shall accept the same as the Buyer’s agent, hold the same in trust for the Buyer and deliver the same forthwith to the Buyer in the exact form received, duly indorsed by such Seller to the Buyer, if required, together with an undated transfer power, if required, covering such certificate duly executed in blank, or if requested, deliver the Trust Interests re-registered in the name of Buyer, to be held by the Buyer subject to the terms hereof as additional security for the Obligations.  Any sums paid upon or in respect of the Trust Interests upon the liquidation or dissolution of REO Subsidiary or any Trust Subsidiary or otherwise shall be paid over to the Buyer as additional security for the Obligations.  If following the occurrence and during the continuation of an Event of Default any sums of money or property so paid or distributed in respect of the Trust Interests shall be received by either Seller, such Seller shall, until such money or property is paid or delivered to the Buyer, hold such money or property in trust for the Buyer segregated from other funds of Sellers, as additional security for the Obligations.

e.     Cash Dividends; Voting Rights.  Unless an Event of Default shall have occurred and be continuing, the applicable Seller shall be permitted to receive all cash dividends or other cash distributions paid in respect of the Trust Interests and to exercise all voting and member rights with respect to the Trust Interests; provided, however, that no vote shall be cast or member right exercised or other action taken which would impair the Trust Interests or which would be inconsistent with or result in a violation of any provision of this Agreement.  Without the prior consent of the Buyer, no Seller shall (i) vote to enable, or take any other action to permit REO Subsidiary or any Trust Subsidiary to issue any trust interests of any nature or to issue any other trust interests convertible into or granting the right to purchase or exchange for any trust interests of REO Subsidiary or any Trust Subsidiary, or (ii) sell, assign, transfer, exchange or

31

otherwise dispose of, or grant any option with respect to, the Trust Interests or (iii) create, incur or permit to exist any Lien or option in favor of, or any claim of any Person with respect to, the Trust Interests, or any interest therein, except for the Lien provided for by this Agreement, or (iv) enter into any agreement (other than the applicable Trust Agreement and this Agreement) or undertaking restricting the right or ability of any Seller to sell, assign or transfer any of the Trust Interests.

f.      Release of Servicing Rights.  The Sellers and Guarantor each acknowledge that they have conveyed all rights to service the Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties to Buyer but subject to the current Servicing Agreements.  Without limiting the generality of the foregoing, and for the avoidance of doubt, each of Sellers and Guarantor grants, assigns and pledges to Buyer a security interest in the Servicing Rights and proceeds related thereto and in all instances, whether now owned or hereafter acquired, now existing or hereafter created.

g.     Intent.  The foregoing provisions (a) and (f) are intended to constitute a security agreement or other arrangement or other credit enhancement related to this Agreement and Transactions hereunder as defined under Sections 101(47)(A)(v) and 741(7)(A)(xi) of the Bankruptcy Code.

52

An Event of Default shall be deemed to be continuing unless expressly waived by Buyer in writing.

16.  Remedies Upon Default

In the event that an Event of Default shall have occurred:

a.     Buyer may, at its option (which option shall be deemed to have been exercised immediately upon the occurrence of an Act of Insolvency of any Seller or any Affiliate), declare an Event of Default to have occurred hereunder and, upon the exercise or deemed exercise of such option, the Repurchase Date for each Transaction hereunder shall, if it has not already occurred, be deemed immediately to occur (except that, in the event that the Purchase Date for any Transaction or Purchase Price Increase Date for any Purchase Price Increase has not yet occurred as of the date of such exercise or deemed exercise, such Transaction or Purchase Price Increase shall be deemed immediately canceled).  Buyer shall (except upon the occurrence of an Act of Insolvency) give notice to Sellers and Guarantor of the exercise of such option as promptly as practicable.

b.     If Buyer exercises or is deemed to have exercised the option referred to in subparagraph (a) of this Section, (i) Sellers’ obligations in such Transactions to repurchase all Purchased Assets, at the Repurchase Price therefor on the Repurchase Date determined in accordance with subparagraph (a) of this Section, shall thereupon become immediately due and payable, (ii) all Income paid after such exercise or deemed exercise shall be retained by Buyer and applied, in Buyer’s sole discretion, to the aggregate unpaid Repurchase Prices for all outstanding Transactions and any other amounts owing by Sellers hereunder, provided, that following the payment of all Obligations, any remaining Income shall be forwarded to the Sellers, and (iii) Sellers shall immediately deliver to Buyer the Asset Files relating to any Purchased Assets, REO Properties or Trust Mortgage Loans subject to such Transactions then in Sellers’ possession or control.

56

c.     Buyer also shall have the right to obtain physical possession, and to commence an action to obtain physical possession, of all Records and files of Sellers, any Trust Subsidiary and REO Subsidiary relating to the Purchased Assets, Trust Mortgage Loans and REO Properties and all documents relating to the Purchased Assets (including, without limitation, any legal, credit or servicing files with respect to the Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties) which are then or may thereafter come in to the possession of Sellers, any Trust Subsidiary and REO Subsidiary or any third party acting for Sellers.  To obtain physical possession of any Purchased Assets, Trust Mortgage Loans and REO Properties held by Custodian, Buyer shall present to Custodian a Trust Receipt.  Without limiting the rights of Buyer hereto to pursue all other legal and equitable rights available to Buyer for Sellers’ failure to perform its obligations under this Agreement, each Seller acknowledges and agrees that the remedy at law for any failure to perform obligations hereunder would be inadequate and Buyer shall be entitled to specific performance, injunctive relief, or other equitable remedies in the event of any such failure. The availability of these remedies shall not prohibit Buyer from pursuing any other remedies for such breach, including the recovery of monetary damages.

d.     Buyer shall have the right to direct all servicers then servicing any Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties to remit all collections thereon to Buyer, and if any such payments are received by Sellers, Sellers shall not commingle the amounts received with other funds of Sellers and shall promptly pay them over to Buyer.  Buyer shall also have the right to terminate any one or all of the servicers then servicing any Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties with or without cause.  In addition, Buyer shall have the right to immediately sell the Purchased Assets, cause any Trust Subsidiary and REO Subsidiary to sell the REO Properties, cause any Trust Subsidiary to sell the Trust Mortgage Loans and liquidate all Repurchase Assets.  Such disposition of Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties may be, at Buyer’s option, on either a servicing-released or a servicing-retained basis.  Buyer shall not be required to give any warranties as to the Purchased Assets, Trust Mortgage Loans or REO Properties with respect to any such disposition thereof.  Buyer may specifically disclaim or modify any warranties of title or the like relating to the Purchased Assets, Trust Mortgage Loans or REO Properties.  The foregoing procedure for disposition of the Purchased Assets, Trust Mortgage Loans or REO Properties and liquidation of the Repurchase Assets shall not be considered to adversely affect the commercial reasonableness of any sale thereof.  Each Seller agrees that it would not be commercially unreasonable for Buyer to dispose of the Purchased Assets, cause the disposition of REO Properties and Trust Mortgage Loans or dispose of the Repurchase Assets or any portion thereof by using Internet sites that provide for the auction of assets similar to the Purchased Assets, Trust Mortgage Loans, REO Properties or the Repurchase Assets, or that have the reasonable capability of doing so, or that match buyers and sellers of assets.  Buyer shall be entitled to place the Purchased Assets or cause the placement of the REO Properties and Trust Mortgage Loans in a pool for issuance of securities

57

at the then-prevailing price for such securities and to sell such securities for such prevailing price in the open market.  Buyer shall also be entitled to sell any or all of such Purchased Mortgage Loans, Trust Mortgage Loans or REO Properties individually for the prevailing price. Buyer shall also be entitled, in its sole discretion to elect, in lieu of selling all or a portion of such Purchased Assets or causing the sale of all or a portion of such REO Properties and Trust Mortgage Loans, to give the Sellers credit for such Purchased Assets and the Repurchase Assets in an amount equal to the Market Value of the Purchased Assets against the aggregate unpaid Repurchase Price and any other amounts owing by the Sellers hereunder.

e.     Upon the happening of one or more Events of Default, Buyer may apply any proceeds from the liquidation of the Purchased Assets and Repurchase Assets to the Repurchase Prices hereunder and all other Obligations in the manner Buyer deems appropriate in its sole discretion.

f.      Each Seller recognizes that the market for the Purchased Assets, Trust Mortgage Loans or REO Properties may not be liquid and as a result it may not be possible for Buyer to sell all of the Purchased Assets on a particular Business Day, or in a transaction with the same purchaser, or in the same manner.  Each Seller further recognizes that Buyer may be unable to effect a public sale of any or all of the Purchased Assets that are Trust Interests, by reason of certain prohibitions contained in the 1934 Act and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers which will be obliged to agree, among other things, to acquire such securities for their own account for investment and not a view to the distribution or resale thereof.  In view of the nature of the Purchased Assets, Trust Mortgage Loans or REO Properties, each Seller agrees that liquidation of any Purchased Asset, Trust Mortgage Loan or REO Property may be conducted in a private sale and at such price as Buyer may deem commercially reasonable.  Buyer shall be under no obligation to delay a sale of any of any Purchased Assets that are the Trust Interests for the period of time necessary to permit the applicable Seller to register the Trust Interests for public sale under the 1934 Act, or under applicable state securities laws, even if such Seller would agree to do so.

g.     Each Seller agrees to use its reasonable efforts to do or cause to be done all such other acts as may be reasonably necessary to make any sale or sales of any portion of the Trust Interests pursuant to this Agreement valid and binding and in compliance with any and all other applicable laws other than registration under applicable securities laws, provided that each Seller shall have no obligation to register the Trust Interests for public sale under the 1934 Act.  Each Seller further agrees that a breach of any of the covenants contained in this Section will cause irreparable injury to Buyer, that Buyer has no adequate remedy at law in respect of such breach and, as a consequence, that each and every covenant contained in this Section shall be specifically enforceable against the Sellers, and each Seller hereby waives and agrees not to assert any defenses against an action for specific

58

performance of such covenants except for defense that no Event of Default has occurred hereunder.

▇.     ▇▇▇▇▇▇▇ shall be liable to Buyer for (i) the amount of all reasonable legal or other expenses (including, without limitation, all costs and expenses of Buyer in connection with the enforcement of this Agreement or any other agreement evidencing a Transaction, whether in action, suit or litigation or bankruptcy, insolvency or other similar proceeding affecting creditors’ rights generally, further including, without limitation, the reasonable fees and expenses of counsel (including the costs of internal counsel of Buyer) incurred in connection with or as a result of an Event of Default, (ii) damages in an amount equal to the cost (including all fees, expenses and commissions) of entering into replacement transactions and entering into or terminating hedge transactions in connection with or as a result of an Event of Default, and (iii) any other loss, damage, cost or expense directly arising or resulting from the occurrence of an Event of Default in respect of a Transaction.

i.      To the extent permitted by applicable law, Sellers shall be liable to Buyer for interest on any amounts owing by Sellers hereunder, from the date Sellers become liable for such amounts hereunder until such amounts are (i) paid in full by Sellers or (ii) satisfied in full by the exercise of Buyer’s rights hereunder.  Interest on any sum payable by Sellers under this Section 16(i) shall accrue at a rate equal to the Post-Default Rate.

j.      Buyer shall have, in addition to its rights hereunder, any rights otherwise available to it under any other agreement or applicable law.

k.     Buyer may exercise one or more of the remedies available to Buyer immediately upon the occurrence of an Event of Default and, except to the extent provided in subsections (a) and (d) of this Section, at any time thereafter without notice to Sellers.  All rights and remedies arising under this Agreement as amended from time to time hereunder are cumulative and not exclusive of any other rights or remedies which Buyer may have.

l.      Buyer may enforce its rights and remedies hereunder without prior judicial process or hearing, and Sellers hereby expressly waive any defenses Sellers might otherwise have to require Buyer to enforce its rights by judicial process.  Sellers also waive any defense (other than a defense of payment or performance) Sellers might otherwise have arising from the use of nonjudicial process, enforcement and sale of all or any portion of the Repurchase Assets, or from any other election of remedies.  Sellers recognize that nonjudicial remedies are consistent with the usages of the trade, are responsive to commercial necessity and are the result of a bargain at arm’s length.

m.    Buyer shall have the right to perform reasonable due diligence with respect to each Seller and the Purchased Assets, Trust Mortgage Loans and REO Properties, which review shall be at the expense of such Seller.

59

Buyer may, in its sole election, engage in repurchase transactions with the Purchased Assets or its interests in REO Properties and Trust Mortgage Loans or otherwise pledge, hypothecate, assign, transfer or otherwise convey the Purchased Assets with a counterparty of Buyer’s choice.  Unless an Event of Default shall have occurred, no such transaction shall relieve Buyer of its obligations to transfer Purchased Assets to Sellers pursuant to Section 4 hereof, or of Buyer’s obligation to credit or pay Income to, or apply Income to the obligations of, Sellers pursuant to Section 7 hereof.  In the event Buyer engages in a repurchase transaction with any of the Purchased Assets or its interests in REO Properties and Trust Mortgage Loans or otherwise pledges or hypothecates any of the Purchased Assets or its interests in REO Properties and Trust Mortgage Loans, Buyer shall have the right to assign to Buyer’s counterparty any of the applicable representations or warranties herein and the remedies for breach thereof, as they relate to the Purchased Assets or its interests in REO Properties and Trust Mortgage Loans that are subject to such repurchase transaction.

21.  Entire Agreement; Severability

This Agreement shall supersede any existing agreements between the parties containing general terms and conditions for repurchase transactions.  Each provision and agreement herein shall be treated as separate and independent from any other provision or agreement herein and shall be enforceable notwithstanding the unenforceability of any such other provision or agreement.

22.  Non assignability

Sellers and Guarantor may assign any of their rights or obligations hereunder only with the prior written consent of Buyer which may be granted or withheld for any reason in its sole discretion.  Buyer may from time to time assign all or a portion of its rights and obligations under this Agreement and the Program Agreements; provided, however that Buyer shall maintain as agent of Sellers, for review by Sellers upon written request, a register of assignees and a copy of an executed assignment and acceptance by Buyer and assignee (“Assignment and Acceptance”), specifying the percentage or portion of such rights and obligations assigned.  No such assignment shall be effective unless such assignee shall be a party hereto and to each Program Agreement to the extent of the percentage or portion set forth in the Assignment and Acceptance, and shall succeed to the applicable rights and obligations of Buyer hereunder. Upon such assignment, Buyer shall, to the extent that such rights and obligations have been so assigned by it to either (i) an Affiliate of Buyer which assumes the obligations of Buyer or (ii)  another Person approved by Sellers (such approval not to be unreasonably withheld) which assumes the obligations of Buyer, be released from its obligations hereunder and under the Program Agreements.  Unless otherwise stated in the Assignment and Acceptance, Sellers shall continue

66

to take directions solely from Buyer unless otherwise notified by Buyer in writing.  Buyer may distribute to any prospective assignee any document or other information delivered to Buyer by Sellers.

23.  Set-off

In addition to any rights and remedies of the Buyer hereunder and by law, the Buyer shall have the right, without prior notice to the Sellers or Guarantor, any such notice being expressly waived by the Sellers and Guarantor to the extent permitted by applicable law to set-off and appropriate and apply against any Obligation from any Seller, Guarantor or any Affiliate thereof to Buyer or any of its Affiliates any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other obligation (including to return excess margin), credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by or due from the Buyer or any Affiliate thereof to or for the credit or the account of any Seller, Guarantor or any Affiliate thereof.  The Buyer agrees promptly to notify the Sellers or Guarantor after any such set off and application made by the Buyer; provided that the failure to give such notice shall not affect the validity of such set off and application.

24.  Binding Effect; Governing Law; Jurisdiction

a.     This Agreement shall be binding and inure to the benefit of the parties hereto and their respective successors and permitted assigns.  Sellers acknowledge that the obligations of Buyer hereunder or otherwise are not the subject of any guaranty by, or recourse to, any direct or indirect parent or other Affiliate of Buyer.  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAW OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PRINCIPLES THEREOF (EXCEPT FOR SECTION 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW).

b.     EACH SELLER AND GUARANTOR HEREBY WAIVE TRIAL BY JURY.  EACH SELLER AND GUARANTOR HEREBY IRREVOCABLY CONSENT TO THE EXCLUSIVE JURISDICTION OF ANY COURT OF THE STATE OF NEW YORK, OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, ARISING OUT OF OR RELATING TO THE PROGRAM AGREEMENTS IN ANY ACTION OR PROCEEDING.  EACH SELLER AND GUARANTOR HEREBY SUBMIT TO, AND WAIVE ANY OBJECTION THEY MAY HAVE TO, EXCLUSIVE PERSONAL JURISDICTION AND VENUE IN ▇▇▇ ▇▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇ AND THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, WITH RESPECT TO ANY DISPUTES ARISING OUT OF OR RELATING TO THE PROGRAM AGREEMENTS.

67

25.  No Waivers, Etc.

No express or implied waiver of any Event of Default by either party shall constitute a waiver of any other Event of Default and no exercise of any remedy hereunder by any party shall constitute a waiver of its right to exercise any other remedy hereunder.  No modification or waiver of any provision of this Agreement and no consent by any party to a departure herefrom shall be effective unless and until such shall be in writing and duly executed by both of the parties hereto.  Without limitation on any of the foregoing, the failure to give a notice pursuant to Section 6(a), 16(a) or otherwise, will not constitute a waiver of any right to do so at a later date.

26.  Intent

a.     The parties intend that each Transaction is a “repurchase agreement” as that term is defined in Section 101 of the Bankruptcy Code (except insofar as the type of Mortgage Loans subject to such Transaction or the term of such Transaction would render such definition inapplicable or such Transaction involves a transfer of a Trust Interest), and a “securities contract” as that term is defined in Section 741 of the Bankruptcy Code (except insofar as the type of assets subject to such Transaction would render such definition inapplicable) and that all payments hereunder are transfers made in connection with a “repurchase agreement” and a “securities contract” (as so defined).

b.     The parties further intend that Buyer’s rights to terminate or accelerate Transactions hereunder and to liquidate Purchased Assets delivered to Buyer in connection with Transactions hereunder, are contractual rights to liquidate such Purchased Assets, or terminate or accelerate such Transactions, as applicable, as described in Sections 555 and 559 of the Bankruptcy Code, as amended.

c.     The parties agree and acknowledge that if a party hereto is an “insured depository institution,” as such term is defined in the Federal Deposit Insurance Act, as amended (“FDIA”), then each Transaction hereunder is a “qualified financial contract,” as that term is defined in FDIA and any rules, orders or policy statements thereunder (except insofar as the type of assets subject to such Transaction would render such definition inapplicable).

d.     It is understood that this Agreement constitutes a “netting contract” as defined in and subject to Title IV of the Federal Deposit Insurance Corporation Improvement Act of 1991 (“FDICIA”) and each payment entitlement and payment obligation under any Transaction hereunder shall constitute a “covered contractual payment entitlement” or “covered contractual payment obligation”, respectively, as defined in and subject to FDICIA (except insofar as one or both of the parties is not a “financial institution” as that term is defined in FDICIA).

e.     The parties further intend this Agreement to be a “repurchase agreement” and a “securities contract,” within the meaning of Section 559 and Section 555, respectively, of the Bankruptcy Code.

68

f.      For U.S. federal tax purposes, each of the Sellers, the Guarantor, the Buyer, and each Buyer assignee by acquiring an interest in any Transaction agree to treat and report each Transaction as indebtedness issued by PennyMac Mortgage Investment Trust, PennyMac Corp., or PennyMac Mortgage Investment Trust Holdings I, LLC as the case may be, which indebtedness, in the case of each obligor, shall have but a single maturity for purposes of Code section 7701(i)(2)(A)(ii) and U.S. Treasury Regulation section 301.7701(i)-1(e).

27.  Disclosure Relating to Certain Federal Protections

The parties acknowledge that they have been advised that:

a.     in the case of Transactions in which one of the parties is a broker or dealer registered with the SEC under Section 15 of the 1934 Act, the Securities Investor Protection Corporation has taken the position that the provisions of the SIPA do not protect the other party with respect to any Transaction hereunder;

b.     in the case of Transactions in which one of the parties is a government securities broker or a government securities dealer registered with the SEC under Section 15C of the 1934 Act, SIPA will not provide protection to the other party with respect to any Transaction hereunder; and

c.     in the case of Transactions in which one of the parties is a financial institution, funds held by the financial institution pursuant to a Transaction hereunder are not a deposit and therefore are not insured by the Federal Deposit Insurance Corporation or the National Credit Union Share Insurance Fund, as applicable.

28.  Power of Attorney

Sellers hereby authorize Buyer to file such financing statement or statements relating to the Repurchase Assets without Sellers’ signature thereon as Buyer, at its option, may deem appropriate.  Sellers hereby appoint Buyer as Sellers’ agent and attorney-in-fact to execute any such financing statement or statements in Sellers’ name and to perform all other acts which Buyer deems appropriate to perfect and continue its ownership interest in and/or the security interest granted hereby, if applicable, and to protect, preserve and realize upon the Repurchase Assets, including, but not limited to, the right to endorse notes, complete blanks in documents, transfer servicing, and sign assignments on behalf of each Seller as its agent and attorney-in-fact.  This agency and power of attorney is coupled with an interest and is irrevocable without Buyer’s consent.  Sellers shall pay the filing costs for any financing statement or statements prepared pursuant to this Section 28.  In connection with the foregoing, the Sellers agree to execute a power of attorney, in the form of Exhibit D hereto (the “Power of Attorney”), to be delivered on the date hereof.  Sellers shall cause PennyMac Loan Services, LLC, REO Subsidiary and any Trust Subsidiary to execute a Power of Attorney in the form of Exhibit E-1, Exhibit E-2, and Exhibit E-3 respectively, hereto.  Notwithstanding the foregoing, the powers of attorney granted thereunder may be exercised only during the occurrence and continuance of any Default hereunder.

69

29.  Buyer May Act Through Affiliates

Buyer may, from time to time, designate one or more Affiliates for the purpose of performing any action hereunder.

30.  Indemnification; Obligations

a.     Each of each Seller and Guarantor agrees to hold Buyer and each of its respective Affiliates and their officers, directors, employees, agents and advisors (each, an “Indemnified Party”) harmless from and indemnify each Indemnified Party (and will reimburse each Indemnified Party as the same is incurred) against all liabilities, losses, damages, judgments, costs and expenses (including, without limitation, reasonable fees and expenses of counsel) of any kind which may be imposed on, incurred by, or asserted against any Indemnified Party relating to or arising out of this Agreement, any Transaction Request or Purchase Price Increase Request, any Program Agreement, the Master Trust Agreement or any transaction contemplated hereby or thereby resulting from anything other than the Indemnified Party’s gross negligence or willful misconduct.  Each of each Seller and Guarantor also agrees to reimburse each Indemnified Party for all reasonable expenses in connection with the enforcement of this Agreement and the exercise of any right or remedy provided for herein, any Transaction Request or Purchase Price Increase Request, and any Program Agreement, including, without limitation, the reasonable fees and disbursements of counsel.  Each Seller’s and Guarantor’s agreements in this Section 30 shall survive the payment in full of the Repurchase Price and the expiration or termination of this Agreement.  Each of each Seller and Guarantor hereby acknowledges that its obligations hereunder are recourse obligations of such Seller and Guarantor and are not limited to recoveries each Indemnified Party may have with respect to the Purchased Assets.  Each of each Seller and Guarantor also agrees not to assert any claim against Buyer or any of its Affiliates, or any of their respective officers, directors, employees, attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to the facility established hereunder, the actual or proposed use of the proceeds of the Transactions or Purchase Price Increases, this Agreement or any of the transactions contemplated thereby.  THE FOREGOING INDEMNITY AND AGREEMENT NOT TO ASSERT CLAIMS EXPRESSLY APPLIES, WITHOUT LIMITATION, TO THE NEGLIGENCE (BUT NOT GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF THE INDEMNIFIED PARTIES.

b.     Without limitation to the provisions of Section 4, if any payment of the Repurchase Price of any Transaction or Purchase Price Increase is made by Sellers other than on the then scheduled Repurchase Date thereto as a result of an acceleration of the Repurchase Date pursuant to Section 16 or for any other reason, Sellers shall, upon demand by Buyer, pay to Buyer an amount sufficient to compensate Buyer for any losses, costs or expenses that it may reasonably incur as of a result of such payment.

70

c.     Without limiting the provisions of Section 30(a) hereof, if any Seller fails to pay when due any costs, expenses or other amounts payable by it under this Agreement, including, without limitation, fees and expenses of counsel and indemnities, such amount may be paid on behalf of such Seller by Buyer, in its sole discretion.

31.  Counterparts

This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original, and all such counterparts shall together constitute one and the same instrument.

32.  Confidentiality

a.     This Agreement and its terms, provisions, supplements and amendments, and notices hereunder, are proprietary to Buyer and shall be held by each Seller and Guarantor in strict confidence and shall not be disclosed to any third party without the written consent of Buyer except for (i) disclosure to Sellers’ or Guarantor’s direct and indirect Affiliates and Subsidiaries, attorneys or accountants, but only to the extent such disclosure is necessary and such parties agree to hold all information in strict confidence, or (ii)  disclosure required by law, rule, regulation or order of a court or other regulatory body.  Notwithstanding the foregoing or anything to the contrary contained herein or in any other Program Agreement, the parties hereto may disclose to any and all Persons, without limitation of any kind, the federal, state and local tax treatment of the Transactions, any fact relevant to understanding the federal, state and local tax treatment of the Transactions, and all materials of any kind (including opinions or other tax analyses) relating to such federal, state and local tax treatment and that may be relevant to understanding such tax treatment; provided that Sellers may not disclose the name of or identifying information with respect to Buyer or any pricing terms (including, without limitation, the Pricing Rate, Commitment Fee, Purchase Price Percentage and Purchase Price) or other nonpublic business or financial information (including any sublimits and financial covenants) that is unrelated to the federal, state and local tax treatment of the Transactions and is not relevant to understanding the federal, state and local tax treatment of the Transactions, without the prior written consent of the Buyer.

b.     Notwithstanding anything in this Agreement to the contrary, the Sellers in all material respects shall comply with all applicable local, state and federal laws, including, without limitation, all privacy and data protection law, rules and regulations that are applicable to the Purchased Assets, Trust Mortgage Loans and REO Properties and/or any applicable terms of this Agreement (the “Confidential Information”).  The Sellers understand that the Confidential Information may contain “nonpublic personal information”, as that term is defined in Section 509(4) of the ▇▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Act (the “Act”), and the Sellers agree to maintain such nonpublic personal information that it receives hereunder in accordance with the Act and other applicable federal and state privacy laws.  The

71

Sellers shall implement such physical and other security measures as shall be necessary to (a) ensure the security and confidentiality of the “nonpublic personal information” of the “customers” and “consumers” (as those terms are defined in the Act) of Buyer or any Affiliate of Buyer which the Sellers hold, (b) protect against any threats or hazards to the security and integrity of such nonpublic personal information, and (c) protect against any unauthorized access to or use of such nonpublic personal information. The Sellers represent and warrant that they have implemented appropriate measures to meet the objectives of Section 501(b) of the Act and of the applicable standards adopted pursuant thereto, as now or hereafter in effect.  Upon request, the Sellers will provide evidence reasonably satisfactory to allow Buyer to confirm that the providing party has satisfied its obligations as required under this Section.  Without limitation, this may include Buyer’s review of audits, summaries of test results, and other equivalent evaluations of the Sellers.  The Sellers shall notify Buyer immediately following discovery of any breach or compromise of the security, confidentiality, or integrity of nonpublic personal information of the customers and consumers of Buyer or any Affiliate of Buyer provided directly to the Sellers by Buyer or such Affiliate.  The Sellers shall provide such notice to Buyer by personal delivery, by facsimile with confirmation of receipt, or by overnight courier with confirmation of receipt to the applicable requesting individual.

33.  Recording of Communications

Buyer, Sellers and Guarantor shall have the right (but not the obligation) from time to time to make or cause to be made tape recordings of communications between its employees and those of the other party with respect to Transactions.  Buyer, Sellers and Guarantor consent to the admissibility of such tape recordings in any court, arbitration, or other proceedings.  The parties agree that a duly authenticated transcript of such a tape recording shall be deemed to be a writing conclusively evidencing the parties’ agreement.

34.  Commitment Fee

Sellers shall pay to Buyer in immediately available funds, due and owing on the date hereof, a non-refundable Commitment Fee.  The Commitment Fee shall be paid in four equal installments as set forth in the Pricing Side Letter.  All such payments shall be made in Dollars, in immediately available funds, without deduction, set-off or counterclaim, to Buyer at such account designated by Buyer.

35.  Reserved

36.  Periodic Due Diligence Review

Sellers acknowledge that Buyer has the right to perform continuing due diligence reviews with respect to the Sellers and the Purchased Assets, Trust Mortgage Loans and REO Properties, for purposes of verifying compliance with the representations, warranties and specifications made hereunder, for the purpose of performing quality control review of the Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties or otherwise, and Sellers

72

agree that upon reasonable (but no less than one (1) Business Day’s) prior notice unless an Event of Default shall have occurred, in which case no notice is required, to Sellers, Buyer or its authorized representatives will be permitted during normal business hours to examine, inspect, and make copies and extracts of, the Asset Files and any and all documents, data, records, agreements, instruments or information relating to such Purchased Assets, Trust Mortgage Loans and REO Properties (including, without limitation, quality control review) in the possession or under the control of Sellers and/or the Custodian.  Sellers also shall make available to Buyer a knowledgeable financial or accounting officer for the purpose of answering questions respecting the Asset Files and the Purchased Assets, Trust Mortgage Loans and REO Properties.  Without limiting the generality of the foregoing, Sellers acknowledge that Buyer may purchase Mortgage Loans and REO Properties from Sellers based solely upon the information provided by Sellers to Buyer in the Asset Schedule and the representations, warranties and covenants contained herein, and that Buyer, at its option, has the right at any time to conduct a partial or complete due diligence review on some or all of the Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties purchased in a Transaction, including, without limitation, ordering BPOs, new credit reports and new appraisals on the related Mortgaged Properties or REO Properties and otherwise re-generating the information used to determine the Market Value of such Purchased Mortgage Loan, Trust Mortgage Loan or REO Property.  Sellers agree to cooperate with Buyer and any third party underwriter, including, but not limited to, providing Buyer and any third party underwriter with access to any and all documents, records, agreements, instruments or information relating to such Purchased Mortgage Loans, Trust Mortgage Loans and REO Properties in the possession, or under the control, of Sellers.  Each Seller further agrees that Sellers shall pay all out-of-pocket costs and expenses incurred by Buyer in connection with Buyer’s activities pursuant to this Section 36 (“Due Diligence Costs”).

37.  Authorizations

Any of the persons whose signatures appear on Schedule 2 are authorized, acting singly, to act for Sellers or Buyer, as the case may be, under this Agreement.

38.  Acknowledgement Of Anti-Predatory Lending Policies

Buyer has in place internal policies and procedures that expressly prohibit its purchase of any High Cost Mortgage Loan.

39.  Documents Mutually Drafted

The Sellers and the Buyer agree that this Agreement and each other Program Agreement prepared in connection with the Transactions set forth herein have been mutually drafted and negotiated by each party, and consequently such documents shall not be construed against either party as the drafter thereof.

The Sellers make the following representations and warranties to the Buyer, with respect to the Purchased Mortgage Loans subject to a Transaction and Trust Mortgage Loans owned by any Trust Subsidiary, as applicable, that as of the Purchase Date for the purchase of Purchased Mortgage Loans subject to a Transaction by the Buyer from a Seller,  and as of the Purchase Price Increase Date for the acquisition of Trust Mortgage Loans by any Trust Subsidiary, as applicable, and as of the date of this Agreement and any Transaction hereunder relating to the Purchased Mortgage Loans or Trust Mortgage Loans is outstanding and at all times while the Program Agreements and any Transaction hereunder is in full force and effect.  For purposes of this Schedule 1 and the representations and warranties set forth herein, a breach of a representation or warranty shall be deemed to have been cured with respect to the Purchased Mortgage Loans or Trust Mortgage Loans if and when the Sellers have taken or caused to be taken action such that the event, circumstance or condition that gave rise to such breach no longer adversely affects such Purchased Mortgage Loans or Trust Mortgage Loans.

(a)   Data.  The information on the Asset Schedule correctly and accurately reflects the information contained in the Sellers’ records (including, without limitation, the Asset File, as applicable) in all material respects. The information contained under each of the headings in the Asset Schedule is true, complete and correct in all material respects.

(b)   No Error, Omission, Fraud etc.  No fraud, misrepresentation, material error or omission or gross negligence, has taken place on the part of the Sellers or, to the best of Sellers’ knowledge any other party in connection with the origination of the Mortgage Loan, the determination of the value of the Mortgaged Property, or the sale or servicing of the Mortgage Loan.

(c)   Regulatory Compliance.  At the time of origination, or if modified, the date of modification, each Mortgage Loan complied in all material respects with all then-applicable federal, state, and local laws, including (without limitation) usury, truth-in-lending, real estate settlement procedures, consumer credit protection, equal credit opportunity, predatory and abusive lending laws, disclosure or unfair and deceptive practice laws or such noncompliance was cured subsequent to origination, as permitted by applicable law.  The servicing and collection practices used by the related Servicer with respect to each Mortgage Loan have at all times complied in all material respects with all applicable federal, state, and local laws.  While the Mortgage Loan has been serviced by the related Servicer, it has been serviced in accordance with the terms of the Mortgage Note or any applicable forbearance plan or bankruptcy plan.

(d)   Ownership.   Immediately prior to the transfer and assignment of the Mortgage Loan pursuant to this Agreement, the applicable Seller was the sole owner and holder of the Mortgage Loan (except that the applicable Trust Subsidiary was the sole owner and holder of the related Trust Mortgage Loan) free and clear of any and all liens, pledges, charges, or security interests of any nature and had full right and authority to sell and assign the same. Upon

Schedule 1-A-1

consummation of a Transaction with respect to the Mortgage Loan, the Buyer shall acquire good and marketable title to the Purchased Mortgage Loans.

(e)   Enforceability and Priority of Lien.  (A) The Mortgage is a valid, subsisting, and enforceable first lien on the property therein described, the Mortgaged Property is free and clear of all encumbrances and liens having priority over the lien of the Mortgage except for, (i) the lien of current real property taxes and assessments not yet due and payable, (ii) covenants, conditions, and restrictions, rights of way, easements, and other matters of public record as of the date of recording of such mortgage acceptable to mortgage lending institutions in the area in which the Mortgaged Property is located, (iii) liens created pursuant to any federal, state, or local law, regulation, or ordinance affording liens for the costs of clean-up of hazardous substances or hazardous wastes or for other environmental protection purposes, and (iv) such other matters to which like properties are commonly subject that do not individually or in aggregate materially interfere with the benefits of the security intended to be provided by the Mortgage; and (B) any security agreement, chattel mortgage, or equivalent document related to and delivered to the Custodian with any Mortgage establishes a valid and subsisting first lien on the property described therein.

(f)    Mortgage Loan Legal and Binding.  (A) The Mortgage Note, the related Mortgage, and other agreements executed in connection therewith are genuine, and each is the legal, valid, and binding obligation of the maker thereof, enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, or other similar laws affecting the enforcement of creditors’ rights generally and by general equity principles (regardless of whether such enforcement is considered in a proceeding in equity or at law); and (B) to the best of Sellers’ knowledge, all parties to the Mortgage Note and the Mortgage had legal capacity to execute the Mortgage Note and the Mortgage, and each Mortgage Note and Mortgage has been duly and properly executed by the Mortgagor and delivered by the parties.

(g)   Customary Provisions.  The Mortgage and related 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 Mortgaged Property of the benefits of the security provided thereby, including (i) in the case of a Mortgage designated as a deed of trust by trustee’s sale, and (ii) otherwise by judicial foreclosure.  There is no homestead or other exemption available to the Mortgagor that would interfere with such right of foreclosure.

(h)   No Prior Modifications.  If a Mortgage Loan has been modified after acquisition by the applicable Seller or Trust Subsidiary, the current and applicable modified terms are reflected on the Asset Schedule and the signed modification documents are in the related loan file.

(i)    Taxes Paid.  Except as disclosed to Buyer, all taxes, and insurance premiums, and, to the best of the applicable Seller’s knowledge, homeowner or similar association fees, charges and assessments, governmental assessments, and water, sewer and municipal charges, which previously became due and owing have been paid, or an escrow of funds has been established, to the extent permitted by law, in an amount sufficient to pay for every such item which remains unpaid.

Schedule 1-A-2

(j)    No Damage/Condemnation.  To the best of Sellers’ knowledge, the Mortgaged Property is undamaged by water, fire, earthquake, earth movement other than earthquake, windstorm, flood, tornado, defective construction materials or work, or similar casualty (excluding casualty from the presence of hazardous wastes or hazardous substances) to affect adversely the value of the Mortgaged Property as security for the Mortgage Loan as reflected in the value of the Mortgage Loan; and to the best of Sellers’ knowledge, there is no proceeding (pending or threatened) for the total or partial condemnation of the Mortgaged Property.

(k)   Predatory Lending Regulations; High Cost Loans.  No Mortgage Loan (a) is subject to Section 226.32 of Regulation Z or any similar state law (relating to high interest rate credit/lending transactions), (b) is a High Cost Mortgage Loan or (c) contains any term or condition, or involves any loan origination practice, that has been defined as “predatory” under any applicable federal, state, county or municipal law, or that has been expressly categorized as an “unfair” or “deceptive” term, condition or practice in any such applicable federal, state, county or municipal law.  No predatory or deceptive lending practices, including, without limitation, the extension of credit without regard to the ability of the Mortgagor to repay and the extension of credit which has no apparent benefit to the Mortgagor, were employed in the origination of the Mortgage Loan.

(l)    Existence of Title Insurance.  The Mortgage Loan (except any Mortgage Loan secured by a Mortgaged Property located in any jurisdiction for which an opinion of counsel of the type customarily rendered in such jurisdiction in lieu of title insurance is instead received) is covered by an American Land Title Association mortgagee title insurance policy or other generally acceptable form of policy or insurance issued by a title insurer acceptable to ▇▇▇▇▇▇ ▇▇▇ or ▇▇▇▇▇▇▇ Mac, issued by a title insurer acceptable to ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac insuring the originator and its successors, and assigns, as to the first priority lien of the Mortgage in the original or current principal amount of the Mortgage Loan and 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 public record as of the date of recording of such mortgage acceptable to mortgage lending institutions in the area in which the Mortgaged Property is located or specifically referred to in the appraisal performed in connection with the origination of the related Mortgage Loan, (c) liens created pursuant to any federal, state, or local law, regulation, or ordinance affording liens for the costs of clean-up of hazardous substances or hazardous wastes or for other environmental protection purposes, and (d) 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. The Sellers or the Trust Subsidiary, as the case may be, or any other person on behalf of the Sellers or the Trust Subsidiary, as the case may be,  are the sole insured of such mortgagee title insurance policy.  The assignment of such mortgagee title insurance policy does not require any consent of or notification to the insurer which has not been obtained or made.  No claims have been made under such mortgagee title insurance policy.

(m)  Hazard Insurance; Flood Insurance.  The Mortgaged Property securing each Mortgage Loan is insured by an insurer acceptable to ▇▇▇▇▇▇ Mae or ▇▇▇▇▇▇▇ Mac against loss by fire and such hazards as are covered under a standard extended coverage endorsement in an amount that is not less than the value.  If the Mortgaged Property is a condominium unit, it is

Schedule 1-A-3

included under the coverage afforded by a blanket policy for the project. If upon origination of the Mortgage Loan, the improvements on the Mortgaged Property were in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards, a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration is in effect with a generally acceptable insurance carrier in an amount representing commercially reasonable coverage.  Each Mortgage obligates the Mortgagor thereunder to maintain all such insurance at the Mortgagor’s cost and expense.

(n)   Mortgage Recorded.  With respect to any Mortgage that has not been recorded in the name of MERS, as agent for the holder from time to time of the Mortgage Note, each original Mortgage was recorded or submitted for recordation in the jurisdiction in which the Mortgaged Property is located and all subsequent assignments of the original Mortgage have been delivered in the appropriate form for recording in all jurisdictions in which such recordation is appropriate.

(o)   Litigation.  Other than any customary claim or counterclaim arising out of any foreclosure or collection proceeding relating to any Mortgage Loan, there is no litigation, proceeding or governmental investigation pending, or any order, injunction or decree outstanding, existing or relating to the Mortgage Loan or the related Mortgaged Property.

(p)   Property Value.  For each Mortgage Loan where a BPO was provided, such BPO was provided by a licensed real estate broker or realtor in the jurisdiction where the Mortgaged Property is located. The person performing any BPO received no benefit from, and such person’s compensation or flow of business from the Sellers were not affected by, the acquisition of the Mortgage Loan by the Sellers or any other applicable transferee.

(q)   Location and Type of Mortgaged Property.  Each Mortgaged Property is located in an Acceptable State as identified in the Custodial Mortgage Loan Schedule and consists of a one- to four-unit residential property, which may include, but is not limited to, a single-family dwelling, townhouse, condominium unit, or unit in a planned unit development.  No Mortgaged Property is a cooperative or a manufactured home.

(r)    Insurance Coverage Not Impaired.  With respect to any Mortgage Loan that is not covered under an umbrella insurance policy of the related Servicer, with respect to any insurance policy including, but not limited to, hazard, title, or mortgage insurance covering a Mortgage Loan and the related Mortgaged Property, neither (i) the originator nor (ii) any prior holder has engaged in, and the Sellers have 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.

(s)   Environmental Laws.  To the best of Sellers’ knowledge, the Mortgaged Property is currently in material compliance with all applicable environmental laws pertaining to environmental hazards including, without limitation, asbestos.

Schedule 1-A-4

(t)    Deeds of Trust.  In the event that the Mortgage constitutes a deed of trust, a trustee, duly qualified under applicable law to serve as such, has been properly designated and currently so serves and is named in the Mortgage, and no fees or expenses are or will become payable by the Buyer or any other applicable transferee to the trustee under the deed of trust, except in connection with a trustee’s sale after default by the Mortgage.

(u)   Due-On-Sale.  The Mortgage contains an enforceable provision, to the extent not prohibited by applicable law as of the date of such Mortgage, for the acceleration of the payment of the unpaid principal balance of the Mortgage Loan in the event that the Mortgaged Property is sold or transferred without the prior written consent of the mortgagee.

(v)   Leases.  The Mortgaged Property is either a fee simple estate or a long-term residential lease.  If the Mortgage Loan is secured by a long-term residential lease, to the best of Sellers’ knowledge: (A) the terms of such 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 such consent is in the Asset 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 such lease do not allow the termination thereof upon the lessee’s default without the holder of the Mortgage being entitled to receive written notice of, 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 such lease is not less than 15 years; (D) the term of such lease does not terminate earlier than five years after the maturity date of the Mortgage Note; and (E) the Mortgaged Property is located in a jurisdiction in which the use of leasehold estates for residential properties is an accepted practice.

(w)  Complete Asset Files.  For each Mortgage Loan, all of the required Mortgage Loan documents have been delivered to the Custodian in accordance with the Custodial Agreement and all Mortgage Loan documents necessary to foreclose on the Mortgaged Property are included in the Asset File delivered to the Custodian.  No material documentation is missing from the Asset File in possession of Custodian, unless such documentation is subject to a Servicer request for release of documents and a foreclosure attorney acknowledgment in form and substance acceptable to Buyer.  Each of the documents and instruments specified to be included in the Asset File is executed and in due and proper form, and each such document or instrument is in form acceptable to the applicable federal or state regulatory agency.

(x)            No Construction Loans; Reverse Mortgage Loans; Home Equity Lines of Credit.  No Mortgage Loan (i) was made in connection with the construction or rehabilitation of a Mortgaged Property where construction loan proceeds are still being disbursed, (ii) is a reverse mortgage loan or (iii) is a home equity line of credit.

(y)   No Rescission.  (A) No Mortgage Note or Mortgage is subject to any right of rescission, set-off, counterclaim, or defense, including the defense of usury, nor will the operation of any of the terms of the Mortgage Note or Mortgage, or the exercise of any right thereunder, render the Mortgage Note or Mortgage unenforceable, in whole or in part, or subject it to any right of rescission, set-off, counterclaim, or defense, including the defense of usury; and

Schedule 1-A-5

(B) to the best of the applicable Seller’s knowledge, no such right of rescission, set-off, counterclaim, or defense has been asserted with respect thereto.

Schedule 1-A-6

(h)   Title Insurance.  The REO Property (and the Unrecorded REO Property Deed upon its submission) is covered by an owner’s mortgage title insurance policy or an attorney’s opinion of title, or such other generally acceptable form of policy or insurance issued by a title insurer qualified to do business in the jurisdiction where the REO Property is located, insuring the owner of the REO Property, its successors and assigns as to the first priority lien of the Mortgage in the original principal amount of the Mortgage Loan.  Either the REO Subsidiary or a Trust Subsidiary, as applicable, is the insured under such mortgage title insurance policy.  No claim has been made under such owner’s title insurance policy, and the Sellers, have not done, by act or omission, anything which would impair the coverage of such lender’s title insurance policy.
