(iii)          the execution, delivery and performance by the Depositor of this Agreement and the consummation of the transactions contemplated hereby do not require the consent or approval of, the giving of notice to, the registration with, or the taking of any other action in respect of, any state, federal or other governmental authority or agency, except such as has been obtained, given, effected or taken prior to the date hereof;

(iv)          this Agreement has been duly executed and delivered by the Depositor and, assuming due authorization, execution and delivery by the Trustee, the Master Servicer, SPS and the Securities Administrator, constitutes a valid and binding obligation of the Depositor enforceable against it in accordance with its terms except as such enforceability may be subject to (A) applicable bankruptcy and insolvency laws and other similar laws affecting the enforcement of the rights of creditors generally and (B) general principles of equity regardless of whether such enforcement is considered in a proceeding in equity or at law;

Section 2.04 Discovery of Breach; Repurchase of Mortgage Loans.

(a)          Pursuant to the Mortgage Loan Purchase and Sale Agreement, the Seller has represented and warranted as of the Closing Date that, immediately prior to its transfer of the Mortgage Loans under the Mortgage Loan Purchase and Sale Agreement, the Seller owned and had good, valid and marketable title to the Mortgage Loans free and clear of all liens, mortgages, deeds of trust, pledges, security interests, charges, encumbrances or other claims and each of the Depositor and the Trustee intend that the Mortgage Loans (including any Qualified Substitute Mortgage Loans) included in the Trust Fund satisfy such representation and warranty. In addition, pursuant to the Mortgage Loan Purchase and Sale Agreement, the Seller represented and warranted to the Depositor that the Seller is obligated to cure, repurchase or substitute for any Mortgage Loan as to which there has been an uncured breach of a representation or warranty restated by an Originator to the Trustee pursuant to the related AAR Agreement that materially and adversely affects the value of such Mortgage Loan or the interests of the Trustee for the benefit of the Certificateholders in such Mortgage Loan, but only if each of the following conditions is met: (i) the related Originator fails to cure such breach or repurchase or substitute for such Mortgage Loan after a valid repurchase demand has been made and remains unresolved and (ii) the related Originator is subject to a bankruptcy or insolvency proceeding or such Originator is no longer in existence. With respect to a breach of a representation and warranty made by an Originator pursuant to the related AAR Agreement that materially and adversely affects the value of such Mortgage Loan or the interests of the Trustee for the benefit of the Certificateholders in such Mortgage Loan, if an Originator restated certain representations and warranties to the Trustee as of a date prior to the Closing Date, the Seller is obligated with respect to such representations and warranties that were true and correct as of the date the related Originator restated such representations and warranties to the Trustee, but not true and correct as of the Closing Date to cure a breach or repurchase from the Trust Fund or substitute for each affected Mortgage Loan. In any AAR Agreement where the related Originator restated representations and warranties to the Trustee as of the Closing Date, the Seller shall not have the obligation described in the prior sentence. Any exceptions identified at the time the Seller purchased a Mortgage Loan shall not be considered a breach of the underwriting guideline representation and warranty provided that such exceptions and the related compensating factors are accurately described in the exhibit that identifies the exceptions.

- 54 -

In addition, in no event will any obligation which the Seller may have to cure, repurchase or substitute for any Mortgage Loans for which there has been a breach of any representation and warranty survive (to the extent such obligation has not expired earlier) beyond the earlier of (a) the termination of the Trust Fund and (b) the payment of all amounts due on the related Mortgage Loan.

(b)          It is understood and agreed that the representations and warranties set forth in the Mortgage Loan Purchase and Sale Agreement and the Seller’s obligation to cure, repurchase or substitute a Mortgage Loan pursuant to the Mortgage Loan Purchase and Sale Agreement shall survive delivery of the Trustee Mortgage Files and the sale and assignment of each Mortgage Loan to the Trustee and shall continue throughout the term of this Agreement. Upon discovery by the Depositor or the Seller (each of such parties hereby agreeing to give written notice thereof to the Trustee and the other of such parties) of (i) a breach by the Seller of any representation or warranty under the Mortgage Loan Purchase and Sale Agreement in respect of any Mortgage Loan or (ii) a breach of a representation or warranty of an Originator pursuant to the related AAR Agreement as a result of which the Seller is required to cure, substitute for or repurchase such Mortgage Loan pursuant the Mortgage Loan Purchase and Sale Agreement (each a “Defective Mortgage Loan”), the Trustee, or its designee, shall promptly notify the Seller and the Depositor in writing of such breach and request that the Seller cure or cause the cure of such breach within 90 days from the earlier of the date that the Seller discovered or was notified of such breach, and if the Seller does not cure or cause the cure of such breach in all material respects during such period, the Trustee shall enforce the Seller’s obligation under the Mortgage Loan Purchase and Sale Agreement to repurchase from the Trust Fund at the Repurchase Price or substitute for such Mortgage Loan on or prior to the Determination Date following the expiration of such 90-day period; provided, however, that, in connection with any such breach that could not reasonably have been cured within such 90-day period, the Seller shall be required to repurchase or substitute for such Mortgage Loan no later than 120 days after its discovery or notice of such breach; and provided further, that if such breach would cause the Mortgage Loan to be other than a “qualified mortgage” (as defined in the Code), then notwithstanding the previous provisions of this paragraph, the Seller shall be required to repurchase or substitute for the Defective Mortgage Loan within 60 days from the date the defect was discovered. The Repurchase Price for the repurchased Mortgage Loan shall be deposited in the Distribution Account, and the Trustee, or its designee, upon receipt of written certification of such deposit, shall release to the Seller, the related Mortgage File and shall execute and deliver such instruments of transfer or assignment, in each case without recourse, representation or warranty, as either party shall furnish to the Trustee and as shall be necessary to vest in such party any Mortgage Loan released pursuant hereto, and the Trustee, or its designee, shall have no further responsibility with regard to such Trustee Mortgage File (it being understood that the Trustee shall have no responsibility for determining the sufficiency of such assignment for its intended purpose). It is understood and agreed that the obligation of the Seller to cure, to cause the cure of or to repurchase or substitute for any Mortgage Loan as to which such a breach has occurred and is continuing that requires such cure, repurchase or substitution pursuant to the Mortgage Loan Purchase and Sale Agreement shall constitute the sole remedy against the Seller respecting such omission, defect or breach available to the Trustee on behalf of the Certificateholders. Costs and expenses incurred by the Trustee pursuant to this Section 2.04, to the extent not reimbursed by the Seller, shall be reimbursed by the Trust Fund, subject to the limitation in clause (C) of the definition of Available Distribution Amount.

- 55 -

The Originators shall cure the breach, or repurchase or substitute for any Mortgage Loan as to which there has been a breach of any representation and warranty in the related AAR Agreement that materially and adversely affects the value of such Mortgage Loan or the interests of the Trustee for the benefit of the Certificateholders in such Mortgage Loan. Each of the representations and warranties made by an Originator pursuant to the related AAR Agreement will survive until the earlier of (a) the termination of the Trust Fund and (b) the payment of all amounts due on the related Mortgage Loan.

(c)          The Seller hereby agrees to indemnify and hold harmless the Trust Fund, the Trustee, the Master Servicer, the Securities Administrator, the Depositor, the Custodian and each Certificateholder against any and all taxes, claims, losses, penalties, fines, forfeitures, reasonable legal fees and related costs, judgments, and any other costs, fees and expenses that the Trust Fund, the Trustee, the Master Servicer, the Securities Administrator, the Depositor, the Custodian and any Certificateholder may sustain in connection with any actions of the Seller relating to a repurchase of a Mortgage Loan other than in compliance with the terms of this Section 2.04 and the Mortgage Loan Purchase and Sale Agreement, to the extent that any such action causes an Adverse REMIC Event.

Section 2.05 Obligations in Respect of Alleged Breach of Representations and Warranties.

(a)          With respect to any Mortgage Loan that is less than 120 days Delinquent, either (a) the Holders of 66-2/3% or more of the Aggregate Voting Interests of the Senior Certificates or (b) the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding (in either case, the “Directing Holders”) may direct the Trustee to request the complete borrower credit file for a Mortgage Loan from the related Servicer, and to engage a third party (which third party may be selected by the Directing Holders or, if no such selection is made by such Holders, such third party shall be selected by the Trustee) to review the related Mortgage Loan to determine whether the related Originator under the related AAR Agreement or the Seller under the Mortgage Loan Purchase and Sale Agreement, as applicable, is obligated to cure, repurchase or substitute for the related Mortgage Loan pursuant to the terms of the related AAR Agreement or the Mortgage Loan Purchase and Sale Agreement, as applicable, and the Trustee shall follow the directions of such Holders. The costs and expenses of such third party review are to be paid for by the Directing Holders. The related Servicer, pursuant to this Agreement or the related Servicing Agreement, as applicable, shall be required to deliver the related complete borrower credit file to the Trustee as directed by the Trustee without unreasonable delay and, upon receipt of such complete borrower credit file, the Trustee shall be required to deliver electronic copies of the complete borrower credit file to the third party engaged to conduct the review as well as the related Originator or the Seller, as applicable. The Trustee shall be required to enforce any related remedy obligation, including participating in an arbitration or other cause of action, pursuant to and to the extent provided in the related AAR Agreement or Mortgage Loan Purchase and Sale Agreement, as applicable, as directed by, and at the expense of, the Directing Holders; provided that the Trustee shall be obligated to commence its enforcement of a remedy obligation only if (i) the Directing Holders provide written direction to the Trustee to enforce the related remedy obligation within 90 days of delivery by the related Servicer of the related complete borrower credit file and (ii) the Directing Holders have entered into an agreement to provide in advance to the Trustee funds to pay for any and all costs and expenses incurred by the Trustee (including but not limited to engaging a third party) in connection with such enforcement and to provide any indemnification reasonably requested by the Trustee (including but not limited to the Directing Holders’ decision to direct the Trustee to pursue or not to pursue an action based on the results of such review). In connection with any such review and/or action, the Trustee shall be required (but subject to the terms of the applicable agreements) to pursue reimbursement for the fees, costs and expenses of the Trustee from such Originator under the terms of the related AAR Agreement or from the Seller under the terms of the Mortgage Loan Purchase and Sale Agreement, as applicable. If the Trustee recovers any such fees, costs and expenses from the related Originator or the Seller, the Trustee shall pay such amounts to the Directing Holders pursuant to the agreement described in clause (ii) above. Costs and expenses incurred by the Trustee pursuant to this Section 2.05(a) to the extent not reimbursed by the applicable Originator, the Seller or the related Holders, will be reimbursed by the Trust Fund, subject to the limitation in clause (C) of the definition of Available Distribution Amount. For the avoidance of doubt: (i) all costs, expenses and indemnification amounts paid by the Directing Holders shall be paid in the aggregate and such payment shall not be subject to any caps or limitations as may be specified elsewhere in this Agreement, (ii) the third party reviewer as described in this paragraph is not an Independent Reviewer and (iii) the fees of any third party reviewer as described in this paragraph are not Independent Reviewer Fees.

- 56 -

(b)          With respect to any Mortgage Loan that has become 120 days or more Delinquent, the Master Servicer shall provide prompt written notice of such delinquency to the Trustee and the Trustee shall notify the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding. The Trustee shall engage an Independent Reviewer selected by the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding. The Trustee shall direct the related Servicer to provide the related complete borrower credit file to the Independent Reviewer. Upon receipt of the borrower credit file, the Independent Reviewer shall review each such Mortgage Loan that is 120 days or more Delinquent to determine whether the related Originator under the related AAR Agreement or the Seller under the Mortgage Loan Purchase and Sale Agreement, as applicable, is obligated to cure, repurchase or substitute for the related Mortgage Loan pursuant to the terms of the related AAR Agreement or the Mortgage Loan Purchase and Sale Agreement, as applicable. If the Independent Reviewer determines that there has been a breach of a representation and warranty by the related Originator under the related AAR Agreement or by the Seller under the Mortgage Loan Purchase and Sale Agreement, as applicable, for which a remedy is required, the Independent Reviewer shall notify the Trustee of such determination, and the Trustee shall be required to enforce any related cure, repurchase or substitution obligation, including participating in an arbitration or other cause of action, pursuant to the related AAR Agreement or Mortgage Loan Purchase and Sale Agreement, as applicable. Costs and expenses incurred by the Trustee pursuant to this paragraph to the extent not reimbursed by the applicable originator or the shall will be reimbursed by the Trust Fund, subject to the limitation in clause (C) of the definition of Available Distribution Amount.

(c)          Notwithstanding the preceding two paragraphs, if the Seller, the Depositor, the Master Servicer, a Servicer, the Securities Administrator or the Trustee becomes aware of a breach of the representation and warranty made by the related Originator relating to the status of a Mortgage Loan as a “qualified mortgage” (as defined in the REMIC Provisions), such party shall notify the Trustee and the Trustee shall immediately enforce the obligation of the related Originator to repurchase the related Mortgage Loan. If an Originator has breached a representation under the related AAR Agreement stating that a Mortgage Loan is a “qualified mortgage” (as defined in the REMIC Provisions) and the applicable Originator or the Seller (pursuant to the Mortgage Loan Purchase and Sale Agreement), as applicable, fails to repurchase such non-qualified Mortgage Loan within sixty days from the date the defect was discovered, the Depositor shall use commercially reasonable efforts to sell such Mortgage Loan for its fair market value, as determined by the Depositor and which may be less than its outstanding principal balance, within ninety days from the date the defect was discovered. The Trustee will release the applicable Mortgage Loan upon notice by the Master Servicer that it has received the sale price in accordance with the procedures set forth in Section 2.04(a) hereof.

Section 2.06 Intention of Parties.

Notwithstanding any other provision of this Agreement, it is intended by each of the parties hereto that the conveyance of the Depositor’s right, title and interest in and to property constituting the Trust Fund pursuant to this Agreement shall constitute, and shall be construed as, a sale of such property and not a grant of a security interest to secure a loan or other obligation, so that the Trustee shall be the owner of the Trust Fund for the benefit of the holders of the Certificates.

With respect to any references in this Agreement to the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding, the Class 2-A-1 Certificates and Class 2-A-2 Certificates are treated as equal in seniority for this purpose and each of the Class 2-A-1 Certificates and Class 2-A-2 Certificates are treated as senior to the Class 2-A-3 Certificates for this purpose. In any instance in which the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding are entitled to act hereunder, if no such Holder or Holders of the majority of the Class Principal Amount of the such Class of Certificates presents satisfactory proof of ownership to the Trustee or Securities Administrator, as applicable, in a timely manner for the purpose of exercising any such rights assigned thereto under this Agreement, such rights shall be deemed inoperative in such instance, and no transaction party shall be required to delay in taking any action hereunder or under any transaction document in order to wait for the exercise of such rights by such Holder or Holders.

Section 2.10 Obligations in Respect of Proposed Eminent Domain Mortgage Loan Acquisition.

(a)          If the Depositor, the Master Servicer, the Securities Administrator or the Trustee receives actual notice that any governmental entity intends to acquire a Mortgage Loan through the exercise of its power of eminent domain, it shall promptly notify the other parties, and the Securities Administrator, to the extent so notified, shall include such information on the Securities Administrator’s website on the next succeeding Distribution Date. With respect to any Mortgage Loan affected by such action, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding or the Holder or Holders of the majority of the Voting Rights may direct the Trustee to contest such acquisition through appropriate legal proceedings. The Trustee shall not be required to take any action unless the Holders directing the Trustee to take such action agree to provide in advance to the Trustee funds to pay for any fees, costs and expenses incurred by the Trustee and to provide any indemnification reasonably requested by the Trustee. In connection with any such action, the Trustee shall pursue reimbursement for its fees, costs and expenses from the governmental entity, if directed to do so by the Certificateholders that provided such funds to the Trustee as described above. If the Trustee recovers any such fees, costs and expenses, it shall be obligated to pay such amounts to such Certificateholders unless the Certificateholders directing the Trustee have not satisfied their obligations to pay the fees, costs, expenses and indemnities of the Trustee in taking such action, in which case such amounts shall be retained by the Trustee for such purposes. To the extent not reimbursed or indemnified by the governmental entity or the Certificateholders, the Trustee shall be reimbursed or indemnified by the Trust Fund, subject to the limitation in clause (c) of the definition of Available Distribution Amount. Under no circumstances shall the Trustee be responsible for evaluating whether to contest an eminent domain acquisition.

(b)          In the event a Mortgage Loan is acquired by a governmental entity through its exercise of the power of eminent domain, and the Trust Fund is paid (i) the outstanding principal balance of the related Mortgage Loan plus accrued interest, that payment will be treated as a voluntary prepayment in full of the related Mortgage Loan or (ii) less than the outstanding principal balance of the related Mortgage Loan plus accrued interest, that payment will be treated as Net Liquidation Proceeds and the difference between (a) the outstanding principal balance of the related Mortgage Loan plus accrued interest and (b) the Net Liquidation Proceeds will be treated as a Realized Loss.

The Securities Administrator is hereby appointed, and the Securities Administrator hereby accepts its appointment as, initial Certificate Registrar in respect of the Certificates and shall maintain books for the registration and for the transfer of Certificates (the “Certificate Register”). A registration book shall be maintained for the Certificates collectively.

Upon the transfer of any Certificate in accordance with the preceding sentence and subsection (c) below, the Trustee shall execute, and the Authenticating Agent shall authenticate and deliver to the transferee, one or more new Certificates of the same Class and evidencing, in the aggregate, the same aggregate Certificate Principal Amount (or Notional Amount) as the Certificate being transferred.

Certificates delivered upon any such exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Certificates surrendered. No service charge shall be made to a Certificateholder for any exchange of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates. Whenever any Certificates are so surrendered for exchange, the Trustee shall execute, and the Authenticating Agent shall authenticate, date and deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

(c)          No transfer, sale, pledge or other disposition of any Certificate or interest therein shall be made unless that transfer, sale, pledge or other disposition is exempt from the registration and/or qualification requirements of the Securities Act and any applicable state securities laws, or is otherwise made in accordance with the Securities Act and such state securities laws. None of the Depositor, the Trustee, the Securities Administrator or the Certificate Registrar is obligated to register or qualify any Certificates under the Securities Act or any other securities law or to take any action not otherwise required under this Agreement to permit the transfer of any Certificate or interest therein without registration or qualification. Any Certificateholder desiring to effect a transfer of Certificates or interests therein shall, and does hereby agree to, indemnify the Depositor, the Trustee, the Securities Administrator and the Certificate Registrar against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

Account holders or agent members of or participants in Euroclear and Clearstream shall have no rights under this Agreement with respect to such Global Certificates, and the Clearing Agency as registered Holder of the Global Certificates may be treated by the Depositor, the Issuing Entity, the Certificate Registrar, the Securities Administrator and the Trustee (and any agent of any of the foregoing) as the owner of such Global Certificates for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Depositor, the Issuing Entity, the Certificate Registrar, the Securities Administrator or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by any Clearance System or impair, as between the Clearance System and its agent members or participants, the operation of customary practices governing the exercise of the rights of a holder of any Certificates. Requests or directions from, or votes of, the Clearing Agency or any Clearance System with respect to any matter shall not be deemed inconsistent if made with respect to (or in separate proportions corresponding to) different beneficial owners. None of the Depositor, the Issuing Entity, the Certificate Registrar, the Securities Administrator or the Trustee shall have any duty to monitor, maintain records concerning (or determine compliance with any of the restrictions on transfer set forth herein with respect to) owners of beneficial interests in the Global Certificates. None of the Depositor, the Issuing Entity, the Certificate Registrar, the Securities Administrator or the Trustee shall have any liability for the accuracy of the records of the Clearing Agency or any Clearance System, or any actions or omissions of the Clearing Agency or any Clearance System (or of the agent members of or participants in any Clearance System).

(ii)         Regulation S Global Certificate to Rule 144A Global Certificate.

With respect to clause (B) of this Section 3.03(e)(iii), the Certificateholder transferring such beneficial interest will be deemed to have made the representations and warranties contained in the Regulation S Transfer Certificate attached as Exhibit E-2 hereto, and such Certificateholder’s transferee will be deemed to have made the representations and warranties contained in the Investor Representation Letter attached as Exhibit E-3 hereto.

(f)          If a transfer of an interest in a Certificate is to be made without registration under the Securities Act, then the Certificate Registrar shall refuse to register such transfer unless it and the Trustee receive a certificate (upon which certificate such party may conclusively rely) from the Certificateholder desiring to effect such transfer substantially in the form attached as Exhibit E-1 or Exhibit E-2 hereto and a certificate from such Certificateholder’s prospective transferee substantially in the form attached as Exhibit E-3 hereto (as to which, in the case of the Book-Entry Certificates, the Certificateholder and the Certificateholder’s prospective transferee will be deemed to have made the representations and agreements contained therein), to the effect that, among other things, the transfer is being made to a “qualified institutional buyer” (a “QIB”) as defined in Rule 144A under the Securities Act in accordance with Rule 144A or in accordance with Regulation S. No such certifications shall be required of the Depositor or any of its Affiliates or the Initial Purchasers in connection with the initial issuance of the Certificates, any transfer of the Certificates between the Initial Purchasers and the Depositor or any of their Affiliates, or with respect to any transfer of the Certificates between the Depositor and any of its Affiliates.

A Person acquiring a Certificate or any interest therein shall make the applicable certifications set forth in clause (i), (ii) or (iii) below to the Trustee and the Certificate Registrar (which in the case of the Book-Entry Certificates, the prospective transferee will be deemed to have represented such certifications by virtue of its purchase and holding of such Certificate), upon which certification the Trustee and the Certificate Registrar may rely without further inquiry or investigation, that each beneficial owner of a Certificate (other than an ERISA-Restricted Certificate or a Certificate that is not an ERISA-Restricted Certificate but is not subject to an ERISA-Qualifying Underwriting) shall represent that (i) it is not, and is not acting on behalf of or using assets of, a Plan investor; (ii) it has acquired and is holding such Certificate in reliance on the Underwriter’s Exemption, and it understands that there are certain conditions to the availability of the Underwriter’s Exemption, including that the Senior Certificates, Class B-1, Class B-2 or Class B-3 Certificates, as applicable, must be rated, at the time of purchase, not lower than “BBB-” (or its equivalent) by at least one Rating Agency; or (iii) if the Certificate has been issued in an ERISA-Qualifying Underwriting, (1) it is an insurance company, (2) the source of funds used to acquire or hold the certificate or interest therein is an “insurance company general account,” as such term is defined in Section V(e) of Prohibited Transaction Class Exemption, or PTCE, 95-60, and (3) the conditions in Sections I and III of PTCE 95-60 have been satisfied.

- 66 -

(g)          (i)          No transfer of an ERISA-Restricted Certificate or a Certificate that is not subject to an ERISA-Qualifying Underwriting in the form of a Definitive Certificate shall be made to any Person or shall be effective unless the Certificate Registrar, on behalf of the Securities Administrator, has received (A) a certificate substantially in the form of Exhibit G hereto (or Exhibit B, in the case of a Residual Certificate) from such transferee or (B) in the case of an ERISA-Restricted Certificate that is not a Residual Certificate, an Opinion of Counsel satisfactory to the Certificate Registrar to the effect that the purchase or holding of such a Certificate is permissible under applicable law, will not constitute or result in non-exempt prohibited transactions under Title I of ERISA or Section 4975 of the Code and will not subject the Certificate Registrar, the Trustee, the Master Servicer, the Depositor or the Securities Administrator to any obligation in addition to those undertaken in this Agreement. Each Transferee of an ERISA-Restricted Certificate or a Certificate that is not an ERISA-Restricted Certificate but is not subject to an ERISA-Qualifying Underwriting that is a Book-Entry Certificate shall be deemed to have made the representations set forth in Exhibit G. The preparation and delivery of the certificate and opinions referred to above shall not be an expense of the Trust Fund, the Certificate Registrar, the Trustee, the Master Servicer, the Depositor or the Securities Administrator.

Notwithstanding the foregoing, no opinion or certificate shall be required for the initial issuance of the ERISA-Restricted Certificates. The Certificate Registrar shall have no obligation to monitor transfers of Book-Entry Certificates that are ERISA-Restricted Certificates and shall have no liability for transfers of such Certificates in violation of the transfer restrictions. The Certificate Registrar shall be under no liability to any Person for any registration of transfer of any ERISA-Restricted Certificate that is in fact not permitted by this Section 3.03(g) and none of the Securities Administrator, the Trustee or the Paying Agent shall have any liability for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered by the Certificate Registrar in accordance with the foregoing requirements. The Securities Administrator, on behalf of the Trustee, shall be entitled, but not obligated, to recover from any Holder of any ERISA-Restricted Certificate that was in fact a Plan or a Person acting on behalf of, or an entity holding “plan assets” of, a Plan any payments made on such ERISA-Restricted Certificate at and after either such time. Any such payments so recovered by the Securities Administrator shall be paid and delivered by the Securities Administrator to the last preceding Holder of such Certificate that is not such a Plan or Person acting on behalf of, or an entity holding “plan assets” of, a Plan.

(ii)         If any ERISA-Restricted Certificate, or any interest therein, is acquired or held in violation of the provisions of the preceding three paragraphs, then upon receipt by the Certificate Registrar of written notice that the registration of transfer of such ERISA-Restricted Certificate was not permitted by this Section 3.03(g), the next preceding permitted beneficial owner will be treated as the beneficial owner of that ERISA-Restricted Certificate, retroactive to the date of transfer to the purported beneficial owner. Any purported beneficial owner whose acquisition or holding of an ERISA-Restricted Certificate, or interest therein, was effected in violation of the provisions of the preceding paragraph shall indemnify to the extent permitted by law and hold harmless the Depositor and the Certificate Registrar from and against any and all liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition or holding.

(i)          Notwithstanding anything to the contrary contained herein, no Residual Certificate may be owned, pledged or transferred, directly or indirectly, by or to (i) a Disqualified Organization or (ii) an individual, corporation or partnership or other person unless such person is (A) not a Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate in connection with the conduct of a trade or business within the United States and has furnished the transferor and the Certificate Registrar with an effective Internal Revenue Service Form W-8ECI or successor form at the time and in the manner required by the Code (any such person who is not covered by clause (A) or (B) above is referred to herein as a “Non-permitted Foreign Holder”). Solely for purposes of this paragraph 3.03(i), “Non-U.S. Person” means an individual, corporation, partnership or other person other than (i) a citizen or resident of the United States; (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States or any state thereof, including for this purpose, the District of Columbia; (iii) an estate that is subject to U.S. federal income tax regardless of the source of its income; (iv) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States trustees have authority to control all substantial decisions of the trust; and, (v) to the extent provided in Treasury regulations, certain trusts in existence on August 20, 1996 that are treated as United States persons prior to such date and elect to continue to be treated as United States persons.

Prior to and as a condition of the registration of any transfer, sale or other disposition of a Residual Certificate (other than with respect to the initial issuance of the Residual Certificates), the proposed transferee shall deliver to the Certificate Registrar, on behalf of the Trustee, an affidavit in substantially the form attached hereto as Exhibit B representing and warranting, among other things, that such transferee is neither a Disqualified Organization, an agent or nominee acting on behalf of a Disqualified Organization, nor a Non-permitted Foreign Holder (any such transferee, a “Permitted Transferee”), and the proposed transferor shall deliver to the Certificate Registrar an affidavit in substantially the form attached hereto as Exhibit C. In addition, the Certificate Registrar may (but shall have no obligation to) require, prior to and as a condition of any such transfer, the delivery by the proposed transferee of an Opinion of Counsel, addressed to the Certificate Registrar and the Depositor, that such proposed transferee or, if the proposed transferee is an agent or nominee, the proposed beneficial owner, is not a Disqualified Organization, agent or nominee thereof, or a Non-permitted Foreign Holder. Notwithstanding the registration in the Certificate Register of any transfer, sale, or other disposition of a Residual Certificate to a Disqualified Organization, an agent or nominee thereof, or Non-permitted Foreign Holder, such registration shall be deemed to be of no legal force or effect whatsoever and such Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder shall not be deemed to be a Certificateholder for any purpose hereunder, including, but not limited to, the receipt of distributions on such Residual Certificate. The Depositor, the Certificate Registrar, the Trustee, the Securities Administrator and the Paying Agent shall be under no liability to any Person for any registration or transfer of a Residual Certificate to a Disqualified Organization, agent or nominee thereof or Non-permitted Foreign Holder or for the Paying Agent making any payments due on such Residual Certificate to the Holder thereof or for taking any other action with respect to such Holder under the provisions of this Agreement, so long as the transfer was effected in accordance with this Section 3.03(i), unless a Responsible Officer of the Certificate Registrar shall have actual knowledge at the time of such transfer or the time of such payment or other action that the transferee is a Disqualified Organization, or an agent or nominee thereof, or Non-permitted Foreign Holder. The Certificate Registrar shall be entitled, but not obligated, to recover from any Holder of a Residual Certificate that was a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder at the time it became a Holder or any subsequent time it became a Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder, all payments made on such Residual Certificate at and after either such times (and all costs and expenses, including but not limited to attorneys’ fees, incurred in connection therewith). Any payment (not including any such costs and expenses) so recovered by the Certificate Registrar shall be paid and delivered to the last preceding Holder of such Residual Certificate.

- 68 -

If any purported transferee shall become a registered Holder of a Residual Certificate in violation of the provisions of this Section 3.03(i), then upon receipt by the Certificate Registrar of written notice that the registration of transfer of such Residual Certificate was not in fact permitted by this Section 3.03(i), the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of such registration of transfer of such Residual Certificate. The Depositor, the Certificate Registrar, the Securities Administrator, the Trustee and the Paying Agent shall be under no liability to any Person for any registration of transfer of a Residual Certificate that is in fact not permitted by this Section 3.03(i), or for the Paying Agent making any payment due on such Certificate to the registered Holder thereof or for taking any other action with respect to such Holder under the provisions of this Agreement so long as the transfer was registered upon receipt of the affidavit described in the preceding paragraph of this Section 3.03(i).

The following legend shall appear on all Residual Certificates:

Any replacement Certificate issued pursuant to this Section 3.05 shall constitute complete and indefeasible evidence of ownership in the applicable Trust Fund, as if originally issued, whether or not the lost, stolen or destroyed Certificate shall be found at any time.

If after the delivery of such new Certificate, a protected purchaser of the original Certificate in lieu of which such new Certificate was issued presents for payment such original Certificate, the Depositor, the Securities Administrator, the Certificate Registrar, the Paying Agent and the Trustee or any agent shall be entitled to recover such new Certificate from the Person to whom it was delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expenses incurred by the Depositor, the Securities Administrator, the Certificate Registrar, the Paying Agent, the Trustee or any agent in connection therewith.

Upon surrender for cancellation of any one or more temporary Certificates, the Trustee shall execute and the Authenticating Agent shall authenticate and deliver in exchange therefor a like aggregate Certificate Principal Amount of definitive Certificates of the same Class in the authorized denominations. Until so exchanged, the temporary Certificates shall in all respects be entitled to the same benefits under this Agreement as definitive Certificates of the same Class.

The Trustee may appoint a Paying Agent (which may be the Trustee) for the purpose of making distributions to the Certificateholders hereunder.

In the case of each Exchangeable Combination, the Initial Exchangeable Certificates shall be exchangeable for the Exchangeable Certificates related to such Exchangeable Combination in respective denominations determined based on the initial Class Principal Amount or initial Class Notional Amount, as applicable, described on Appendix A hereto, as reduced by distributions of principal pursuant to Section 5.02 and any allocation of Realized Losses and Certificate Writedown Amounts pursuant to Section 5.03 on each Distribution Date prior to the Exchange date, as applicable. Upon any such Exchange, the portions of the Initial Exchangeable Certificates designated for exchange shall be deemed cancelled and replaced by the Exchangeable Certificates issued in exchange therefore. Correspondingly, Exchangeable Certificates related to a Exchangeable Combination may be further designated for exchange for the Initial Exchangeable Certificates or for other Exchangeable Certificates related to a Exchangeable Combination in respective denominations determined based on the proportion that the initial Certificate Principal Amount or initial Class Notional Amount, as applicable, of such Exchangeable Certificates bear to the initial Certificate Principal Amount of the Initial Exchangeable Certificates or the related Exchangeable Certificates, in each case, as set forth in Appendix A.

After receiving such notice, the Securities Administrator will e-mail the Certificateholder with wire payment instructions relating to the Exchange Fee. The original exchange notice (bearing a medallion stamp guarantee) and the exchange fee must be received by the Securities Administrator prior to effecting any such exchange.

The Certificateholder will utilize the Deposit and Withdrawal System at DTC to exchange the Certificates. The Certificates to be exchanged must be in the correct exchange proportions. The Securities Administrator will verify the proposed proportions to ensure that the principal and interest entitlements of the Certificates received equal the entitlements of the Certificates surrendered. If there is an error, the exchange will not occur until such error is corrected. Unless rejected for error, the notice of exchange will become irrevocable on the second Business Day before the proposed exchange date.

- 73 -

In connection with each exchange, the Certificateholder must pay the Securities Administrator a fee equal to $5,000 (the “Exchange Fee”).

Section 5.01        Distributions Generally.

(a)          Subject to Section 7.01 respecting the final distribution on the Certificates, on each Distribution Date the Paying Agent on behalf of the Trustee shall make distributions to holders of Certificates as of the related Record Date in accordance with this Article V. Such distributions shall be made by check mailed to each Certificateholder’s address as it appears on the Certificate Register of the Certificate Registrar or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000, or in the case of any Residual Certificate, a Percentage Interest of not less than 100%, by wire transfer in immediately available funds to an account specified in the request and at the expense of such Certificateholder; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Certificate Registrar’s Corporate Trust Office; provided, further, that the foregoing provisions shall not apply to any Class of Certificates as long as such Certificate remains a Book-Entry Certificate in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Wire transfers will be made at the expense of the Holder requesting such wire transfer by deducting a wire transfer fee from the related distribution. Notwithstanding such final payment of principal of any of the Certificates, each Certificate will remain outstanding until the termination of each REMIC and the payment in full of all other amounts due with respect to the Certificates and at such time such final payment in retirement of any Certificate will be made only upon presentation and surrender of such Certificate at the Certificate Registrar’s Corporate Trust Office. If any payment required to be made on the Certificates is to be made on a day that is not a Business Day, then such payment will be made on the next succeeding Business Day.

(b)          All distributions or allocations made with respect to the Certificateholders within each Class on each Distribution Date shall be allocated among the outstanding Certificates in such Class equally in proportion to their respective initial Class Principal Amounts or initial Class Notional Amounts (or Percentage Interests).

Section 5.02         Distributions From the Distribution Account.

(a)          On each Distribution Date, the Available Distribution Amount for the related Mortgage Pool (in the case of the Senior Certificates) and for the Mortgage Pools in the aggregate (in the case of the Subordinate Certificates), to the extent received by the Securities Administrator, shall be withdrawn by the Paying Agent from funds in the Distribution Account and allocated among the Classes of Senior Certificates and Subordinate Certificates in the following order of priority (in each case, to the extent of the remaining Available Distribution Amount):

(i)          Concurrently, (a) from the Available Distribution Amount for Pool 1, to the Class 1-A-1 Certificates and Class 1-X-1 Certificates, concurrently, on a pro rata basis, based on their Interest Distribution Amounts, in each case such Class’s Interest Distribution Amount and any accrued but unpaid Interest Shortfalls for such Distribution Date and (b) from the Available Distribution Amount for Pool 2, to the Class 2-X-4, Class 2-A-1, Class 2-X-1, Class 2-A-2, Class 2-A-3, Class 2-A-4, Class 2-X-2 and Class 2-A-5 Certificates, concurrently, on a pro rata basis, based on their Interest Distribution Amounts, in each case such Class’s Interest Distribution Amount and any accrued but unpaid Interest Shortfalls for such Distribution Date;

(A)    to the Class 2-A-1 Certificates and Class 2-A-2 Certificates, sequentially, in that order, in each case until the Class Principal Amount thereof is reduced to zero;

(B)     to the Class 2-A-3 Certificates, until the Class Principal Amount thereof is reduced to zero; and

(C)     to the Class 2-A-4 Certificates and Class 2-A-5 Certificates, sequentially, in that order, in each case until the Class Principal Amount thereof is reduced to zero;

notwithstanding the foregoing, on any Distribution Date on and after the Credit Support Depletion Date, the Senior Principal Distribution Amount for Pool 2 shall be distributed to the Class 2-A-1, Class 2-A-2, Class 2-A-3, Class 2-A-4 and Class 2-A-5 Certificates, concurrently, on a pro rata basis, in accordance with their respective Class Principal Amounts, until the aggregate Class Principal Amount thereof has been reduced to zero;

(iii)        to the Class B-1 Certificates, the Interest Distribution Amount and any accrued but unpaid Interest Shortfalls, in each case, for such Class on such date;

(iv)        to the Class B-1 Certificates, such Class’ Subordinate Class Percentage of the Subordinate Principal Distribution Amounts for each of Pool 1 and Pool 2, until its Class Principal Amount has been reduced to zero;

- 83 -

(ix)         to the Class B-4 Certificates, the Interest Distribution Amount and any accrued but unpaid Interest Shortfalls, in each case, for such Class on such date;

(x)          to the Class B-4 Certificates, such Class’ Subordinate Class Percentage of the Subordinate Principal Distribution Amounts for each of Pool 1 and Pool 2, until its Class Principal Amount has been reduced to zero;

(xiii)       To the Class R Certificates, any remaining amounts.

(b)          On each Distribution Date on and after the Credit Support Depletion Date, the Interest Distribution Amounts shall be distributed as set forth in Section 5.02(a)(i) and each of the Senior Principal Distribution Amounts shall be distributed to the Senior Certificates in the related Certificate Group as set forth in Section 5.02(a)(ii); provided that, if there is a shortfall on any Distribution Date in the distribution of the entire Interest Distribution Amount to the Class 1-A-1, Class 1-X-1, Class 2-X-4, Class 2-A-1, Class 2-X-1, Class 2-A-2, Class 2-A-3, Class 2-A-4, Class 2-X-2 and Class 2-A-5 Certificates from the Available Distribution Amount for the related Mortgage Pool, any such shortfall shall be covered to the extent of the interest portion of the Available Distribution Amount for the non-related Mortgage Pool remaining after making interest distributions to the related Classes of Senior Certificates pursuant to Section 5.02(a)(i).

(c)          The portion of the Subordinate Principal Distribution Amount distributed to each Class of Certificates on each Distribution Date pursuant to clauses (a)(iv), (a)(vi), (a)(viii), (a)(x) and (a)(xii) above shall be reduced, in reverse order of priority, by the amount of Capitalization Reimbursement Amount remaining for such Distribution Amount.

(d)          For purposes of distributions of interest in Section 5.02(a) such distributions to a Class of Certificates on any Distribution Date shall be made first, in respect of Current Interest; and second, in respect of Interest Shortfalls. Net Prepayment Interest Shortfalls and Relief Act Shortfalls experienced by a Mortgage Pool on any Distribution Date will be allocated among each Class of related Senior Certificates entitled to distributions in respect of interest and to all Classes of Subordinate Certificates proportionately based on (1) in the case of the Pool 1 Certificates and Pool 2 Certificates, the amount of Net Prepayment Interest Shortfalls and Relief Act Shortfalls experienced by Pool 1 and Pool 2, respectively, and Current Interest otherwise distributable on the Pool 1 Certificates and Pool 2 Certificates, respectively, on such Distribution Date, and (2) in the case of the Subordinate Certificates, the amount of Net Prepayment Interest Shortfalls and Relief Act Shortfalls experienced by Pool 1 and Pool 2 and Current Interest otherwise distributable on the Subordinate Certificates based on the Apportioned Principal Balance for each such Mortgage Pool before taking into account any reductions in such amounts from Interest Shortfalls for such Distribution Date.

(e)          Notwithstanding the priority of distributions set forth in Section 5.02(a), if on any Distribution Date prior to the Credit Support Depletion Date (1) either one of the Rapid Prepayment Conditions is satisfied on such date and (2) the aggregate of the Class Principal Amounts of the Senior Certificates relating to one of the Mortgage Pools has been reduced to zero or will be reduced to zero after giving effect to distributions on such Distribution Date, then that portion of the Available Distribution Amount for each Mortgage Pool described in Section 5.02(a)(iii) that represents principal collections on the Mortgage Loans shall be applied as an additional distribution to the remaining Classes of Senior Certificates in the other Certificate Group, in reduction of, and in proportion to, the Class Principal Amounts thereof.

- 84 -

(f)          If, on any Distribution Date, any Certificate Group would constitute an Undercollateralized Group and the other Certificate Group would constitute an Overcollateralized Group, then notwithstanding Section 5.02(a)(ii), the Available Distribution Amount for an Overcollateralized Group, to the extent remaining following distributions of interest and principal to the related Senior Certificates of that Certificate Group, shall be distributed, up to the sum of the Interest Transfer Amount and the Principal Transfer Amount for the Undercollateralized Group, to the Senior Certificates related to the Undercollateralized Group so that the aggregate Class Principal Amount of those Senior Certificates equals the Aggregate Stated Principal Balance of the Mortgage Loans in the related Mortgage Pool, in payment of accrued but unpaid interest, if any, and then to such Senior Certificates as principal, in the same manner and order of priority as such Senior Certificates would receive other distributions of principal pursuant to Section 5.02(a)(ii).

(g)          For purposes of distributions provided in Section 5.02(a), each Mortgage Pool shall “relate” to the Senior Class of the applicable related Certificate Group.

(h)          In the event that Initial Exchangeable Certificates are exchanged for Exchangeable Certificates as set forth on Appendix A to this Agreement, such Exchangeable Certificates shall be entitled to receive the proportionate share of interest and principal distributions, as applicable, that would otherwise be distributable on the related Initial Exchangeable Certificates, in the order of priority assigned in this Section 5.02.

Section 5.03         Allocation of Realized Losses and Certificate Writedown Amounts; Subsequent Recoveries.

(a)          On or prior to each Distribution Date, the Master Servicer shall calculate the aggregate Realized Losses for such Distribution Date based on the information with respect to losses as reported to it by each Servicer.

(b)          On each Distribution Date, the Securities Administrator shall allocate the principal portion of Realized Losses as follows:

first, to the Classes of Subordinate Certificates in reverse order of their respective numerical Class designations (beginning with the Class B-5 Certificates and ending with the Class B-1 Certificates) until the Class Principal Amount of each such Class is reduced to zero; and

second, in the case of a Mortgage Loan in Pool 1 that sustained such loss, to the Class 1-A-1 Certificates, until the Class Principal Amount thereof is reduced to zero, assuming, for purposes of this calculation, that no Exchanges have occurred; and in the case of a Mortgage Loan in Pool 2 that sustained such loss, to the Class 2-A-1, Class 2-A-2, Class 2-A-3, Class 2-A-4 and Class 2-A-5 Certificates, concurrently, on a pro rata basis based on their respective Class Principal Amount until the Class Principal Amounts thereof are reduced to zero, assuming, for purposes of this calculation, that no Exchanges have occurred; provided, however, any Realized Losses otherwise allocable to the Class 2-A-1, Class 2-A-2 and Class 2-A-3 Certificates shall first be allocated to the Class 2-A-3 Certificates until the Class Principal Amount of that Class has been reduced to zero, and then to the Class 2-A-1 Certificates and Class 2-A-2 Certificates, concurrently, on a pro rata basis based on their respective Class Principal Amounts, in each case until the Class Principal Amount of that Class has been reduced to zero.

- 85 -

(c)          On each Distribution Date prior to the Credit Support Depletion Date, the Class Principal Amount of the Class of Subordinate Certificates then outstanding with the highest numerical Class designation shall be reduced on each Distribution Date by the Certificate Writedown Amount. On the Credit Support Depletion Date, the Certificate Writedown Amount will first be applied in reduction of the Class Principal Amounts of the Subordinate Certificates then outstanding, and any remaining Certificate Writedown Amount shall be applied to the Senior Certificates related to each Mortgage Pool, on a pro rata basis based on the amount of undercollateralization, if any, with respect to each Mortgage Pool, with any allocation to the Class 2-A-1, Class 2-A-2, Class 2-A-3, Class 2-A-4 and Class 2-A-5 Certificates on a pro rata basis based on their respective Class Principal Amounts until the Class Principal Amounts thereof are reduced to zero; provided, however, any allocation to the Class 2-A-1, Class 2-A-2 and Class 2-A-3 Certificates shall first be allocated to the Class 2-A-3 Certificates until the Class Principal Amount of that Class has been reduced to zero, and then to the Class 2-A-1 Certificates and Class 2-A-2 Certificates, concurrently, on a pro rata basis based on their respective Class Principal Amounts, in each case until the Class Principal Amount of that Class has been reduced to zero. On each Distribution Date after the Credit Support Depletion Date, in the case of Certificate Writedown Amounts on the Pool 1 Mortgage Loans, the Class 1-A-1 Certificates shall be reduced by any Certificate Writedown Amount for Pool 1, until the Class Principal Amount thereof is reduced to zero, assuming, for purposes of this calculation, that no Exchanges have occurred, and in the case of Certificate Writedown Amounts on the Pool 2 Mortgage Loans, the Class 2-A-1, Class 2-A-2, Class 2-A-3, Class 2-A-4 and Class 2-A-5 Certificates shall be reduced by any Certificate Writedown Amount for Pool 2, concurrently, on a pro rata basis based on their respective Class Principal Amount until the Class Principal Amounts thereof are reduced to zero, in each case assuming, for purposes of this calculation, that no Exchanges have occurred; provided, however, any Certificate Writedown Amounts otherwise allocable to the Class 2-A-1, Class 2-A-2 and Class 2-A-3 Certificates will first be allocated to the Class 2-A-3 Certificates until the Class Principal Amount of that Class has been reduced to zero, and then to the Class 2-A-1 Certificates and Class 2-A-2 Certificates, concurrently, on a pro rata basis based on their respective Class Principal Amounts, in each case until the Class Principal Amount of that Class has been reduced to zero.

(d)          Any allocation of a loss pursuant to this section to a Class of Certificates shall be achieved by reducing the Class Principal Amount thereof by the amount of such loss.

(e)          Subsequent Recoveries in respect of the Mortgage Loans in a Mortgage Pool shall be distributed to the Senior Certificates and Subordinate Certificates still outstanding, in accordance with Section 5.02, and the Class Principal Amount of each Class of Certificates then outstanding that has been reduced due to application of a Certificate Writedown Amount or Realized Loss relating to such Mortgage Pool (in the case of any Senior Certificates) will be increased, in order of seniority (with respect to the Pool 2 Certificates, with the Class 2-A-1, Class 2-A-2, Class 2-A-3, Class 2-A-4 and Class 2-A-5 Certificates treated as equal in seniority for this purpose; provided, however, among the Class 2-A-1, Class 2-A-2 and Class 2-A-3 Certificates, the Class 2-A-1 Certificates and Class 2-A-2 Certificates will be treated as senior to the Class 2-A-3 Certificates for this purpose), by the amount of such Subsequent Recovery.

(f)          In the event that Initial Exchangeable Certificates are exchanged for Exchangeable Certificates as set forth on Appendix A to this Agreement, the Exchangeable Certificates will bear the proportionate share of Realized Losses, Interest Shortfalls and Certificate Writedown Amounts allocable to the related Initial Exchangeable Certificates, as applicable and the Class Principal Amount of any Class of Exchangeable Certificates will be increased proportionally to the related Initial Exchangeable Certificates as a result of the application of Subsequent Recoveries.

If (i) any Servicer fails to remit any Advance required to be funded under this Agreement or the related Servicing Agreement or (ii) Five Oaks fails to remit the required amount of any Advance to either Shellpoint Mortgage Servicing or PHH with respect to the Five Oaks MSR Mortgage Loans required under the related Servicing Agreement, the Master Servicer shall itself fund, or shall cause the successor servicer to fund, such Advance. If the Master Servicer determines that an Advance is required, it shall on the Business Day preceding the related Distribution Date immediately following such Determination Date remit to the Securities Administrator from its own funds (or funds advanced by the applicable Servicer for deposit in the Distribution Account) immediately available funds in an amount equal to such Advance. The Master Servicer and each Servicer shall be entitled to be reimbursed for all Advances funded by it; provided, that, with respect to Shellpoint Mortgage Servicing and PHH and the Five Oaks MSR Mortgage Loans, the related Servicer shall reimburse Five Oaks to the extent Five Oaks remitted any Advances to such Servicer. Notwithstanding anything to the contrary herein, in the event the Master Servicer determines in its reasonable judgment that an Advance is nonrecoverable, the Master Servicer shall be under no obligation to make such Advance. If the Master Servicer determines that an Advance is nonrecoverable, it shall, on or prior to the related Distribution Date, deliver an Officer’s Certificate to the Trustee to such effect.

Section 5.06         Master Servicer Compensating Interest Payments.

The amount of the aggregate Master Servicing Fee payable to the Master Servicer in respect of any Distribution Date shall be reduced (but not below zero) by the amount of any Master Servicer Compensating Interest Payment for such Distribution Date. Such amount shall not be treated as an Advance and shall not be reimbursable to the Master Servicer.

Section 5.07         Distributions and Realized Losses on REMIC Regular Interests.

(a)          On each Distribution Date with respect to the REMIC 1 Regular Interests, the Available Distribution Amount distributable as interest shall be deemed to have been distributed as interest pro rata with respect to the REMIC 1 Regular Interests based on their respective amounts of Uncertificated Accrued Interest. On each Distribution Date with respect to the REMIC 1 Regular Interests, Interest Shortfalls shall be allocated among the REMIC 1 Regular Interests pro rata in proportion to their respective amounts of Uncertificated Accrued Interest.

(b)          On each Distribution Date with respect to the REMIC 1 Regular Interests, the remaining Available Distribution Amount distributable with respect to principal shall be deemed to have been distributed to the REMIC 1 Regular Interests in the same amount and priority as principal is distributed to the Corresponding Classes of Certificates until the Uncertificated Class Principal Amount of each such REMIC 1 Regular Interest is reduced to zero.

- 87 -

(c)          Subsequent Recoveries distributed to a Class of Certificates pursuant to the provisions of Section 5.03(e) shall be deemed to have been distributed to the REMIC 1 Regular Interests that correspond to such Class of Certificates giving rise to such Subsequent Recoveries. To the extent that the Class Principal Amount of any Class of Certificates has been increased on account of Subsequent Recoveries pursuant to the provisions of Section 5.03(e), the Uncertificated Class Principal Amount of the corresponding REMIC 1 Regular Interests shall be increased by the same amount that the Class Principal Amount of such Class of Certificates is increased pursuant to the provisions of Section 5.03(e).

(d)          Realized Losses and any Certificate Writedown Amounts allocated by this Section 5.07 to a Class of Certificates shall be allocated to the REMIC 1 Regular Interests in the same amount and priority as Realized Losses and any Certificate Writedown Amounts are allocated to the Corresponding Classes of Certificates until the Uncertificated Class Principal Amount of each such REMIC 1 Regular Interest is reduced to zero.

(e)          On each Distribution Date with respect to the REMIC 2 Regular Interests, the Available Distribution Amount distributable as interest shall be deemed to have been distributed as interest pro rata with respect to the REMIC 2 Regular Interests based on their respective amounts of Uncertificated Accrued Interest. On each Distribution Date with respect to the REMIC 2 Regular Interests, Interest Shortfalls shall be allocated among the REMIC 2 Regular Interests pro rata in proportion to their respective amounts of Uncertificated Accrued Interest.

(f)          On each Distribution Date with respect to the REMIC 2 Regular Interests, the remaining Available Distribution Amount distributable with respect to principal shall be deemed to have been distributed to the REMIC 2 Regular Interests in the same amount and priority as principal is distributed to the Corresponding Classes of Certificates until the Uncertificated Class Principal Amount of each such REMIC 2 Regular Interest is reduced to zero.

(g)          Subsequent Recoveries distributed to a Class of Certificates pursuant to the provisions of subsection 5.03(e) shall be deemed to have been distributed to the REMIC 2 Regular Interests that correspond to such Class of Certificates giving rise to such Subsequent Recoveries.

(iii)        A decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against the Master Servicer, and such decree or order shall have remained in force undischarged or unstayed for a period of 60 days or a Rating Agency reduces or withdraws or threatens to reduce or withdraw the rating of the Certificates because of the financial condition or loan servicing capability of such Master Servicer;

- 101 -

(iv)        The Master Servicer shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, readjustment of debt, marshalling of assets and liabilities, voluntary liquidation or similar proceedings of or relating to the Master Servicer or of or relating to all or substantially all of its property;

(v)         The Master Servicer shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors or voluntarily suspend payment of its obligations;

(vi)        The Master Servicer shall be dissolved, or shall dispose of all or substantially all of its assets, or consolidate with or merge into another entity or shall permit another entity to consolidate or merge into it, such that the resulting entity does not meet the criteria for a successor servicer as specified in Section 9.05 hereof;

(vii)       If a representation or warranty set forth in Section 9.03 hereof shall prove to be incorrect as of the time made in any respect that materially and adversely affects the interests of the Certificateholders, and the circumstance or condition in respect of which such representation or warranty was incorrect shall not have been eliminated or cured within 30 days after the date on which written notice of such incorrect representation or warranty shall have been given to the Master Servicer by the Trustee or the Securities Administrator, or to the Master Servicer, the Securities Administrator and the Trustee by the Holders of more than 50% of the Aggregate Voting Interests of the Certificates;

(ix)         The purchase or holding of any Certificates by the Master Servicer or any master servicer transferee that is an insured depository institution (as such term is defined in the Federal Deposit Insurance Act) such that the Master Servicer or such master servicer transferee is required to consolidate any assets of the Trust Fund on its financial statements under U.S. generally accepted accounting principles;

(x)          Subject to the terms of this Section 6.14(a) and this Agreement, the Master Servicer's long-term unsecured debt rating from S&P shall fall below "BBB" or the short-term unsecured debt rating of the Master Servicer from S&P shall fall below “A-2”; provided, however if the Master Servicer’s long-term unsecured debt rating from S&P is “BBB+” or higher, there shall be no Event of Default ; and

(xi)         Any failure of the Master Servicer to make any Advances when such Advances are due, which failure continues unremedied for a period of one Business Day.

- 102 -

If an Event of Default occurs under Section 6.14(a)(x) of this Agreement, then the Master Servicer shall attempt to cure such default by seeking a waiver of the ratings requirement from S&P. If the Master Servicer obtains a waiver of the ratings requirement from S&P within thirty (30) Business Days following such downgrade, then such Event of Default shall be deemed not to have occurred and the Master Servicer shall continue to act in such capacity in accordance with the terms of this Agreement. If at any time following such request for waiver S&P indicates in writing that such waiver request is denied, or if S&P fails to respond to such waiver request, then the Master Servicer shall have a period of thirty (30) Business Days from the date of such downgrade in which to (i) cure such default by engaging, at its sole cost and expense, an entity with either (a) a long-term debt rating that is “BBB+” or higher or (b) a long-term debt rating that is “BBB” or higher and a short-term unsecured debt rating that is “A-2” or higher that assumes the Master Servicer’s obligation to make Advances and Servicing Advances in the event of a failure by any of the Servicers to make any such advance as required under this Agreement or the applicable Servicing Agreement, as applicable, or (ii) resign as Master Servicer in accordance with the provisions of this Agreement. All fees of such alternate advance provider (as described in clause (i) immediately above) shall be payable by the Master Servicer. If the Master Servicer fails to engage such an entity within such 30-Business Day time period, an Event of Default shall occur and the Trustee shall terminate the Master Servicer and either appoint a successor master servicer or succeed to the responsibilities of the terminated Master Servicer in accordance with this Agreement. In the event of a subsequent downgrade of the Master Servicer occurring after a waiver is granted, the aforementioned waiver request process shall be repeated. If an Event of Default shall occur, then, in each and every case, subject to applicable law, so long as any such Event of Default shall not have been remedied within any period of time as prescribed by this Section, the Trustee, by notice in writing to the Master Servicer (a) may (in the case of an Event of Default described in clauses (i) through (ix) of this Section), and, (b)(I) if so directed in writing by Certificateholders evidencing either (i) more than 50% of the Class Principal Amount (or Class Notional Amount) of each Class of Certificates, or (ii) 50% of the aggregate Class Principal Amount of the Subordinate Certificates (in the case of an Event of Default described in clauses (i) through (ix) of this Section) and (II) upon the occurrence of an Event of Default described in clause (x) or clause (xi) of this Section, shall, terminate all of the rights and obligations of the Master Servicer hereunder and in and to the Mortgage Loans and the proceeds thereof; provided, however, that in the case of the preceding clause (b)(I), the Trustee shall provide written notice to all of the Certificateholders within two Business Days of receiving such direction and shall not terminate the Master Servicer if, within 30 days of sending such written notice, the Trustee has received contrary instructions from Certificateholders evidencing more than 50% of the Aggregate Voting Interests of the Certificateholders. On or after the receipt by the Master Servicer of such written notice, all authority and power of the Master Servicer, and only in its capacity as Master Servicer under this Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee; and the Trustee is hereby authorized and empowered to execute and deliver, on behalf of the defaulting Master Servicer as attorney-in-fact or otherwise, any and all documents and other instruments, and to do or accomplish all other acts or things necessary or appropriate to effect the purposes of such notice of termination, whether to complete the transfer and endorsement or assignment of the Mortgage Loans and related documents or otherwise. The defaulting Master Servicer agrees to cooperate with the Trustee and the Securities Administrator in effecting the termination of the defaulting Master Servicer’s responsibilities and rights hereunder as Master Servicer including, without limitation, notifying Servicers of the assignment of the master servicing function and providing the Trustee or its designee all documents and records in electronic or other form reasonably requested by it to enable the Trustee or its designee to assume the defaulting Master Servicer’s functions hereunder and the transfer to the Trustee for administration by it of all amounts which shall at the time be or should have been deposited by the defaulting Master Servicer in the Distribution Account and any other account or fund maintained with respect to the Certificates or thereafter received with respect to the Mortgage Loans. The Master Servicer being terminated pursuant to this Section 6.14 shall bear all costs of a master servicing transfer, including but not limited to those of the Trustee or Securities Administrator reasonably allocable to specific employees and overhead, legal fees and expenses, accounting and financial consulting fees and expenses, and costs of amending this Agreement, if necessary. If the same Person is acting as both the Securities Administrator and the Master Servicer, then the Trustee shall direct the Depositor to remove the Securities Administrator in accordance with the provisions of Section 6.06(b), and the Depositor promptly upon such direction shall remove the Securities Administrator in accordance therewith.

- 103 -

Notwithstanding the termination of its activities as Master Servicer, each terminated Master Servicer shall continue to be entitled to reimbursement under this Agreement to the extent such reimbursement relates to the period prior to such Master Servicer’s termination. The successor master servicer shall not be required to purchase or reimburse the terminated Master Servicer's Advance receivables. For the avoidance of doubt, to the extent that the terminated Master Servicer and a successor master servicer have each made Advances in respect of the same Mortgage Loan, recovered amounts shall be used to reimburse the terminated Master Servicer and a successor master servicer in the order in which such Advances were made.

When a Responsible Officer of the Trustee has actual knowledge of the occurrence of an Event of Default, the Trustee shall promptly notify the Securities Administrator and each Rating Agency through the Rule 17g-5 Information Provider of the nature and extent of such Event of Default. The Trustee or the Securities Administrator shall promptly give written notice to the Master Servicer upon the Master Servicer’s failure to fund Advances as required under this Agreement.

(b)          Within thirty Business Days after the time the Master Servicer receives a notice of termination from the Trustee pursuant to Section 6.14(a) or the Trustee receives the written resignation of the Master Servicer pursuant to Section 9.06, the Trustee (if it has either (i) a long-term unsecured debt rating of “BBB+” or higher from S&P or (ii) a long-term unsecured debt rating of at least “BBB” from S&P and short-term unsecured debt rating of at least “A-2" from S&P (or such lower long-term unsecured debt rating or lower short-term unsecured debt rating as is otherwise acceptable to S&P)) or another master servicer that satisfies the requirements in Section 9.02 and shall have been appointed by the Trustee, shall be the successor in all respects to the Master Servicer in its capacity as such under this Agreement and with respect to the transactions set forth or provided for herein and shall have all the rights and powers and be subject to all the responsibilities, duties and liabilities relating thereto and arising thereafter placed on the Master Servicer hereunder, including the obligation to make Advances in accordance with Section 5.04; provided, however, that any failure to perform such duties or responsibilities caused by the Master Servicer’s failure to provide information required by this Agreement shall not be considered a default by the Trustee hereunder. The Trustee shall have no responsibility for any act or omission of the Master Servicer other than any act or omission performed by the Trustee in its capacity as a successor master servicer. In addition, the Trustee shall have no liability relating to the representations and warranties of the Master Servicer set forth in Section 9.03. In the Trustee’s capacity as successor master servicer, the Trustee shall have the same limitations on liability herein granted to the Master Servicer. As compensation for acting as successor master servicer hereunder, the Trustee shall be entitled to receive all compensation payable to the Master Servicer under this Agreement, including the Master Servicing Fee, subject to Section 6.14(d).

(c)          Notwithstanding the above, the Trustee may, if it shall be unwilling to continue to so act, or shall, if it is unable to so act, petition a court of competent jurisdiction to appoint, or appoint on its own behalf any established housing and home finance institution servicer, master servicer, servicing or mortgage servicing institution having a net worth of not less than $15,000,000, which is a Xxxxxx Xxx or Xxxxxxx Mac-approved master servicer, that either (i) has a long-term unsecured debt rating of “BBB+” or higher from S&P or (ii) has a long-term unsecured debt rating of at least “BBB” from S&P and short-term unsecured debt rating of at least “A-2" from S&P (or such lower long-term unsecured debt rating or lower short-term unsecured debt rating as is otherwise acceptable to S&P) and meeting such other standards for a successor master servicer as are set forth in this Agreement, as the successor to such Master Servicer in the assumption of all of the responsibilities, duties and liabilities of a master servicer, like the Master Servicer. Further, notwithstanding the above, any entity designated by the Trustee as a successor master servicer may be an Affiliate of the Trustee if either the Trustee or such designated entity has either (i) a long-term unsecured debt rating of “BBB+” or higher from S&P or (ii) a long-term unsecured debt rating of at least “BBB” from S&P and short-term unsecured debt rating of at least “A-2" from S&P (or such lower long-term unsecured debt rating or lower short-term unsecured debt rating as is otherwise acceptable to S&P); provided, however, that, unless such Affiliate meets the net worth requirements and other standards set forth herein for a successor master servicer, the Trustee, in its individual capacity, shall agree, at the time of such designation, to be and remain liable to the Trust Fund for such Affiliate’s actions and omissions in performing its duties hereunder.

- 104 -

The Trustee and such successor shall take such actions, consistent with this Agreement, as shall be necessary to effectuate any such succession and may make other arrangements with respect to the master servicing to be conducted hereunder which are not inconsistent herewith. The Master Servicer shall cooperate with the Trustee and any successor master servicer in effecting the termination of the Master Servicer’s responsibilities and rights hereunder including, without limitation, notifying Mortgagors of the assignment of the master servicing functions and providing the Trustee and successor master servicer, as applicable, all documents and records in electronic or other form reasonably requested by it to enable it to assume the Master Servicer’s functions hereunder and transferring to the Trustee or such successor master servicer, as applicable, all amounts which shall at the time be or which should have been deposited by the Master Servicer in the Distribution Account and any other account or fund maintained with respect to the Certificates or thereafter be received with respect to the Mortgage Loans. Neither the Trustee nor any other successor master servicer shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the predecessor master servicer to deliver, or any delay in delivering, cash, documents or records to it, (ii) the failure of the predecessor master servicer to cooperate as required by this Agreement, (iii) the failure of the predecessor master servicer to deliver the Mortgage Loan data to the Securities Administrator as required by this Agreement or (iv) restrictions imposed by any regulatory authority having jurisdiction over the predecessor master servicer. No successor master servicer (other than the Trustee, with respect to the failure of the Trustee to cooperate as set forth in subclause (ii) below) shall be deemed to be in default hereunder by reason of any failure to make, or any delay in making, any distribution hereunder or any portion thereof caused by (i) the failure of the Securities Administrator to deliver, or any delay in delivering cash, documents or records to it related to such distribution, or (ii) the failure of Trustee or the Securities Administrator to cooperate as required by this Agreement.

(d)          In connection with such appointment and assumption of a successor master servicer, the Trustee may make such arrangements for the compensation of such successor out of payments on Mortgage Loans as it and such successor shall agree; provided, however, that no such compensation shall be in excess of that permitted to the Master Servicer hereunder.

(e)          To the extent that the costs and expenses incurred by the Trustee in connection with any alleged or actual default by the Master Servicer, the termination of the Master Servicer, any appointment of a successor master servicer and/or any transfer and assumption of master servicing by the Trustee or any successor master servicer (including, without limitation, (i) all legal costs and expenses and all due diligence costs and expenses associated with the investigation of any alleged or actual default by the Master Servicer, the evaluation of the potential termination and/or the actual termination of the Master Servicer and the appointment of a successor master servicer and (ii) all Master Servicing Transfer Costs) are not fully and timely reimbursed by the terminated master servicer, then (a) the successor master servicer shall deduct such amounts from any amounts that it otherwise would have paid to the predecessor master servicer in reimbursement of outstanding Advances, and the successor master servicer shall reimburse itself and the Trustee for any unreimbursed costs and expenses, and (b) if the Trustee is not required to be reimbursed by the Master Servicer or if such costs and expenses are not satisfied pursuant to clause (a) within 90 days, then the Trustee and the successor master servicer shall be entitled to reimbursement of such costs and expenses from the Distribution Account, subject to the limitations described in clause (C) of the definition of Available Distribution Amount.

Except as otherwise expressly provided in this Agreement, no remedy provided for by this Agreement shall be exclusive of any other remedy, and each and every remedy shall be cumulative and in addition to any other remedy, and no delay or omission to exercise any right or remedy shall impair any such right or remedy or shall be deemed to be a waiver of any Event of Default.

Upon any such waiver of a past default, such default shall cease to exist, and any event of default of PHH, Shellpoint Mortgage Servicing or Five Oaks under the related Servicing Agreement, or SPS Event of Default or Event of Default hereunder by SPS or the Master Servicer, respectively, arising therefrom shall be deemed to have been remedied for every purpose of the related Servicing Agreement and/or this Agreement, as applicable. No such waiver shall extend to any subsequent or other default or impair any right consequent thereon except to the extent expressly so waived.

Section 6.17         Notification to Holders.

The Trustee shall also, within 45 days after the date when a Responsible Officer of the Trustee has actual knowledge of the occurrence of any Event of Default, give written notice thereof to the Securities Administrator and the Certificateholders, unless such Event of Default shall have been cured or waived prior to the issuance of such notice and within such 45-day period.

(a)          The respective obligations and responsibilities of the Trustee, the Securities Administrator, SPS and the Master Servicer created hereby (other than the obligation of the Securities Administrator to make payments to the Certificateholders as set forth in Section 7.02), shall terminate on the earliest of (i) the final payment or other liquidation of the last Mortgage Loan remaining in the Trust Fund and the disposition of all REO Property, (ii) the distribution of proceeds in connection with the exercise of the Clean-up Call and (iii) the Distribution Date immediately following the Latest Possible Maturity Date; provided, however, that in no event shall the Trust Fund created hereby continue beyond the expiration of 21 years from the death of the last survivor of the descendants of Xxxxxx X. Xxxxxxx, the late Ambassador of the United States to the Court of St. James’s, living on the date hereof. Any termination of the Trust Fund shall be carried out in such a manner so that the termination of each REMIC included therein shall qualify as a “qualified liquidation” under the REMIC Provisions.

(b)          In connection with an exercise of the Clean-up Call, the Trustee, at the direction of the Securities Administrator, shall cause each REMIC to adopt a plan of complete liquidation by complying with the provisions of Section 7.03.

(c)          The Depositor, the Master Servicer, each Servicer, the Securities Administrator and the Custodian shall be reimbursed from the Clean-up Call Price for any Advances, Servicing Advances, accrued and unpaid Servicing Fees, Trustee Fees and Master Servicing Fees or other amounts with respect to the related Mortgage Loans that are reimbursable to such parties under this Agreement, the Servicing Agreements or the Custodial Agreement prior to distributions to any Certificateholder.

(d)          On any date on which the Aggregate Stated Principal Balance of the Mortgage Loans is less than ten percent (10%) of the Aggregate Stated Principal Balance as of the Cut-off Date, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may terminate the Trust Fund by purchasing all of the Mortgage Loans and all property acquired in respect of any Mortgage Loan for the Clean-up Call Price. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise the right described in the preceding sentence, then on any date on which the Aggregate Stated Principal Balance is less than or equal to three percent (3%) of the Aggregate Stated Principal Balance as of the Cut-off Date, the Master Servicer may terminate the Trust Fund by purchasing all of the Mortgage Loans and all property acquired in respect of any Mortgage Loan for the Clean-up Call Price.

Section 7.02         Procedure Upon Redemption and Termination of Trust Fund.

(a)          If on any Determination Date the Master Servicer determines that there are no outstanding Mortgage Loans, and no other funds or assets in the Trust Fund other than the funds in the Distribution Account, the Master Servicer shall direct the Securities Administrator promptly to send a final distribution notice to each Certificateholder. Such notice shall specify (A) the Distribution Date upon which final distribution on the Certificates of all amounts required to be distributed to Certificateholders pursuant to Section 5.02 will be made upon presentation and surrender of the Certificates at the Certificate Registrar’s Corporate Trust Office, and (B) that the Record Date otherwise applicable to such Distribution Date is not applicable, distribution being made only upon presentation and surrender of the Certificates at the office or agency of the Certificate Registrar therein specified. The Securities Administrator shall give such notice to the Trustee, the Servicers, the Master Servicer and the Certificate Registrar at the time such notice is given to Holders of the Certificates. Upon any such termination, the duties of the Certificate Registrar with respect to the Certificates shall terminate.

Upon termination of the Trust Fund, the Securities Administrator shall terminate, or request the Master Servicer to terminate, the Distribution Account and any other account or fund maintained with respect to the Certificates, subject to the Securities Administrator’s obligation hereunder to hold all amounts payable to Certificateholders in trust without interest pending such payment.

(b)          In the event that all of the Holders do not surrender their Certificates for cancellation within three months after the time specified in the termination notice, the Securities Administrator shall give a second written notice to the remaining Certificateholders to surrender their Certificates for cancellation and receive the final distribution with respect thereto. If within one year after the second notice any Certificates shall not have been surrendered for cancellation, the Securities Administrator may take appropriate steps to contact the remaining Certificateholders concerning surrender of such Certificates, and the cost thereof shall be paid out of the amounts distributable to such Holders. If within two years after the second notice any Certificates shall not have been surrendered for cancellation, the Securities Administrator shall, subject to applicable state law relating to escheatment, hold all amounts distributable to such Holders for the benefit of such Holders. No interest shall accrue on any amount held by the Securities Administrator and not distributed to a Certificateholder due to such Certificateholder’s failure to surrender its Certificate(s) for payment of the final distribution thereon in accordance with this Section.

(c)          Any reasonable expenses incurred by the Securities Administrator or the Trustee in connection with any redemption or termination or liquidation of the Trust Fund shall be reimbursed from proceeds received from the liquidation of the Trust Fund.

(a)          Any termination of the Trust Fund in connection with the Clean-up Call or involving any other sale of assets of the Trust Fund prior to the final payment or other liquidation of the last Mortgage Loan remaining in the Trust Fund shall be effected in accordance with the following additional requirements, unless the Securities Administrator and the Trustee receive an Opinion of Counsel (at the expense of the party exercising any right of termination), addressed to the Securities Administrator and the Trustee to the effect that the failure of the Trust Fund to comply with the requirements of this Section 7.03 will not result in an Adverse REMIC Event:

(ii)         Any sale of the Mortgage Loans upon the exercise of a Clean-up Call shall be a sale for cash and shall occur at or after the time of adoption of such a plan of complete liquidation and prior to the time of making of the final payment on or credit to the Certificates, and upon the closing of such a sale, the Trustee shall deliver or cause the Custodian to deliver the Mortgage Loans to the purchaser thereof as instructed by the party exercising the Clean-up Call;

(iii)        On the date specified for final payment of the Certificates, the Securities Administrator shall make final distributions of principal and interest on the Certificates in accordance with Section 5.02 and, after payment of, or provision for payment of any outstanding expenses, distribute or credit, or cause to be distributed or credited, to the Holders of the Residual Certificates all cash on hand after such final payment (other than cash retained to meet claims), and the Trust Fund (and each REMIC) shall terminate at that time; and

(iv)        In no event may the final payment on or credit to the Certificates or the final distribution or credit to the Holders of the Residual Certificates be made after the 89th day from the date on which the plan of complete liquidation is adopted.

(b)          By its acceptance of a Residual Certificate, each Holder thereof hereby agrees to accept the plan of complete liquidation adopted by the Trustee at the direction of the Securities Administrator under this Section and to take such other action in connection therewith as may be reasonably requested by the Securities Administrator or any Servicer.

Article IX

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS BY THE MASTER SERVICER

Section 9.01         Duties of the Master Servicer; Enforcement of Servicer’s and Master Servicer’s Obligations.

(a)          The Master Servicer, on behalf of the Trustee and the Certificateholders shall, from and after the Closing Date, monitor the performance of the Servicers and Five Oaks under this Agreement and the related Servicing Agreement, as applicable. In performing its obligations hereunder, the Master Servicer shall act in a manner consistent with Accepted Master Servicing Practices. Furthermore, the Master Servicer shall consult with each Servicer and Five Oaks as necessary from time to time to carry out the Master Servicer’s obligations hereunder, shall receive and review all reports, information and other data provided to the Master Servicer by each Servicer and Five Oaks and shall enforce the obligation of each Servicer and Five Oaks to duly and punctually to perform and observe the covenants, duties, obligations and conditions to be performed or observed by such Servicer or Five Oaks under this Agreement or the related Servicing Agreement, as applicable. The Master Servicer shall independently and separately monitor each Servicer’s servicing activities with respect to each related Mortgage Loan in respect of the provisions of this Agreement or the related Servicing Agreement, as applicable, reconcile the reports and other data provided to the Master Servicer pursuant to the previous sentence on a monthly basis based on the Mortgage Loan data provided to the Master Servicer by or on behalf of the Depositor on the Closing Date (upon which data the Master Servicer shall be entitled to rely and with respect to which the Master Servicer shall have no obligation to confirm or verify) and coordinate corrective adjustments to the records of each Servicer and the Master Servicer, and based on such reconciled and corrected information, the Master Servicer shall provide such information to the Securities Administrator as shall be necessary in order for it to prepare the statements specified in Section 4.02, and prepare any other information and statements required to be forwarded by the Master Servicer hereunder. The Master Servicer shall reconcile the results of its Mortgage Loan monitoring with the actual remittances of each Servicer to the Distribution Account pursuant to this Agreement or the related Servicing Agreement, as applicable. In its review of the activities of any Servicer or Five Oaks, the Master Servicer may rely upon an Officer’s Certificate of such Servicer or Five Oaks, as applicable (or similar document signed by an officer of such Servicer or Five Oaks, as applicable), and with regard to each Servicer, such Servicer’s Assessment of Compliance and related Accountant’s Attestation or other accountants’ report provided to the Master Servicer pursuant to this Agreement or the related Servicing Agreement, as applicable, with regard to such Servicer’s compliance with the terms of this Agreement or the related Servicing Agreement, as applicable. Subject to Section 9.08, the Master Servicer shall not be responsible or liable for the day-to-day servicing activities of any Servicer or Five Oaks or for any unlawful act or omission, breach, negligence, fraud, willful misconduct or bad faith of any Servicer or Five Oaks.

Upon the occurrence of an SPS Event of Default hereunder or event that, unless cured, would constitute grounds for termination of PHH or Shellpoint Mortgage Servicing under the related Servicing Agreement, the Master Servicer shall promptly notify the Trustee and the Depositor thereof, and shall specify in such notice the action, if any, the Master Servicer is taking in respect of such default. So long as any such event of default shall be continuing, the Master Servicer may, and shall, if it determines such action to be in the best interests of Certificateholders, (i) terminate all of the rights and powers of such Servicer pursuant to the applicable provisions of this Agreement or the related Servicing Agreement, as applicable; (ii) exercise any rights it may have to enforce this Agreement against SPS or the related Servicing Agreement against the related Servicer; and/or (iii) waive any such default under this Agreement or the related Servicing Agreement, as applicable, or take any other action with respect to such default as is permitted hereunder or thereunder. Notwithstanding the immediately preceding sentence, if the event of default is the failure of a Servicer to remit any payment required to be made under the terms of this Agreement or the related Servicing Agreement, as applicable, and such failure continues unremedied for the duration of the applicable grace period, then the Master Servicer shall terminate all of the rights and powers of such Servicer pursuant to the applicable provisions of this Agreement or the related Servicing Agreement, as applicable, unless any waiver described under Section 6.16 shall have been obtained. If an event of default relating to Five Oak’s failure to remit any payment required to be made to PHH or Shellpoint Mortgage Servicing with respect to the Five Oaks MSR Mortgage Loans under the terms of the related Servicing Agreement occurs and such failure continues unremedied for the duration of the applicable grace period, then the Master Servicer shall terminate all of the rights and powers of Five Oaks pursuant to the applicable provisions of the related Servicing Agreement, unless any waiver described under Section 6.16 shall have been obtained.

- 116 -

(b)          Upon any termination by the Master Servicer of the rights and powers of a Servicer or Five Oaks pursuant to this Agreement or the related Servicing Agreement, as applicable, the rights and powers of such Servicer or Five Oaks, as applicable, with respect to the related Mortgage Loans shall vest in the Master Servicer and the Master Servicer shall be the successor in all respects to such Servicer or Five Oaks as owner of the servicing rights for the Five Oaks MSR Mortgage Loans, as applicable, with respect to such Mortgage Loans under this Agreement or the related Servicing Agreement, as applicable, unless or until the Master Servicer shall have appointed a successor servicer, with the consent of the Trustee, such consent not to be unreasonably withheld (or in the case of a termination of Shellpoint Mortgage Servicing or PHH with respect to the Five Oaks MSR Mortgage Loans, Five Oaks may appoint a successor to such Servicer with the consent of the Master Servicer, such consent not to be unreasonably withheld); provided further that, with respect to the appointment of a successor servicer, in accordance under this Agreement or the applicable provisions of the related Servicing Agreement, such successor servicer shall be (i) a Xxxxxx Xxx- or Xxxxxxx Mac-approved Person that is a member in good standing of MERS and (ii) have a net worth of at least $15,000,000; provided, further, that no Trustee or Master Servicer consent shall be required if the successor servicer was a Servicer on the Closing Date; provided, further, that it is understood and agreed by the parties hereto that there will be a period of transition (not to exceed 90 days) before the actual servicing functions can be fully transferred to a successor servicer (including the Master Servicer). In the event that the Master Servicer terminates Five Oaks, the ownership of the servicing rights with respect to the related Mortgage Loans shall transfer to the Master Servicer on behalf of the Trust and the Master Servicer is authorized hereunder to transfer such servicing rights to any successor it appoints. Upon appointment of a successor servicer, as authorized under this Section 9.01(b), unless the successor servicer shall have assumed the obligations of the terminated Servicer under this Agreement or the related Servicing Agreement, as applicable, the Master Servicer, the Trustee and such successor servicer (and Five Oaks in the case of the Five Oaks MSR Mortgage Loans) shall enter into a servicing agreement in a form substantially similar to the servicing provisions of this Agreement or the affected Servicing Agreement, as applicable, in a form mutually agreed upon by the parties thereto. In connection with any such appointment, the Master Servicer or Five Oaks, as applicable, may make such arrangements for the compensation of such successor servicer as it and such successor shall agree. The Master Servicer in its sole discretion shall have the right to agree to compensation of a successor servicer that is in excess of that permitted to such Servicer under this Agreement or the related Servicing Agreement, as applicable, if such increase is, in its good faith judgment, necessary or advisable to engage a successor servicer. Notwithstanding anything herein to the contrary, in no event shall the Master Servicer be liable for any Servicing Fee or for any differential between the amount of the Servicing Fee paid to the original servicer and the amount necessary to induce any successor servicer to act as successor servicer hereunder. To the extent the successor servicer assumes the obligations of the terminated Servicer under this Agreement or the related Servicing Agreement, as applicable, the Master Servicer may amend this Agreement or the related Servicing Agreement, as applicable, to effect such change to the Servicing Fee without the consent of the Certificateholders.

- 117 -

The Master Servicer shall pay the costs of such enforcement (including the termination of any Servicer or Five Oaks, the appointment of a successor servicer or the transfer and assumption of the servicing by the Master Servicer) at its own expense and shall be reimbursed therefor (i) by the terminated Servicer or Five Oaks, as applicable, (ii) from a general recovery resulting from such enforcement only to the extent, if any, that such recovery exceeds all amounts due in respect of the related Mortgage Loans, (iii) from a specific recovery of costs, expenses or attorney’s fees against the party against whom such enforcement is directed, or (iv) to the extent that such amounts described in (i)-(iii) above are not received by the Master Servicer within 30 days of the Master Servicer's request for reimbursement therefor, from the Trust Fund, as provided in Section 9.04. To the extent the Master Servicer recovers amounts described in (i)-(iii) above subsequent to its reimbursement from the Trust Fund pursuant to (iv) above, then the Master Servicer promptly will reimburse such amounts to the Trust Fund.

If the Master Servicer assumes the servicing with respect to any of the Mortgage Loans, it will not assume liability for the representations and warranties of any Servicer or Five Oaks being replaced or for the errors or omissions of such Servicer or Five Oaks.

(c)          Upon any termination of the rights and powers of any Servicer or Five Oaks pursuant to this Agreement or the related Servicing Agreement, as applicable, the Master Servicer shall promptly notify the Trustee, the Securities Administrator and each Rating Agency through the Rule 17g-5 Information Provider, specifying in such notice that the Master Servicer or any successor servicer, as the case may be, has succeeded the Servicer under this Agreement or the related Servicing Agreement or has succeeded Five Oaks under the related Servicing Agreement, as applicable, which notice shall also specify the name and address of any such successor servicer or successor owner of the servicing rights, as applicable.

Section 9.02         Assumption of Master Servicing by Trustee.

(a)          In the event the Master Servicer shall for any reason no longer be the Master Servicer (including by reason of any Event of Default under this Agreement), the Trustee shall thereupon, in accordance with the terms of Section 6.14 hereof, assume all of the rights and obligations of such Master Servicer hereunder and under the related Servicing Agreement entered into with respect to the Mortgage Loans (if the Trustee has either (i) a long-term unsecured debt rating of at least “BBB+” from S&P or (ii) a long-term unsecured debt rating of at least “BBB” from S&P and a short-term unsecured debt rating of at least “A-2” from S&P (or such lower long-term unsecured debt rating or lower short-term unsecured debt rating as is otherwise acceptable to S&P)) or shall appoint as successor master servicer a Xxxxxx-Xxx or Xxxxxxx Mac-approved servicer that is acceptable to the Depositor and each Rating Agency and that has either (i) a long-term unsecured debt rating of at least “BBB+” from S&P or (ii) a long-term unsecured debt rating of at least “BBB” from S&P and a short-term unsecured debt rating of at least “A-2” from S&P (or such lower long-term unsecured debt rating or lower short-term unsecured debt rating as is otherwise acceptable to S&P). The Trustee, its designee or any successor master servicer appointed by the Trustee shall be deemed to have assumed all of the replaced Master Servicer’s interest herein and, with respect to the related Servicing Agreement, shall be deemed to have assumed all of the replaced Master Servicer's interest herein and therein to the same extent as if such related Servicing Agreement had been assigned to the assuming party; provided that the replaced Master Servicer shall not thereby be relieved of any liability or obligations of such replaced Master Servicer this Agreement or the related Servicing Agreement, as applicable, accruing prior to its replacement as Master Servicer, and shall be liable to the Trustee or any successor master servicer therefor, and hereby agrees to indemnify and hold harmless the Trustee or any successor master servicer from and against all costs, damages, expenses and liabilities (including reasonable attorneys’ fees) incurred by the Trustee or any successor master servicer as a result of such liability or obligations of the replaced Master Servicer and in connection with the Trustee’s or such successor master servicer’s assumption (but not its performance, except to the extent that costs or liability of the Trustee or any successor master servicer are created or increased as a result of negligent or wrongful acts or omissions of the replaced Master Servicer prior to its replacement as Master Servicer) of the Master Servicer’s obligations, duties or responsibilities thereunder.

- 118 -

(b)          The replaced Master Servicer shall, upon request of the Trustee but at the expense of such replaced Master Servicer, deliver to the assuming party all documents and records relating to the servicing hereunder by SPS or of PHH,Shellpoint Mortgage Servicing and Five Oaks under the related Servicing Agreement and the related Mortgage Loans and an accounting of amounts collected and held by it, and otherwise use its best efforts to effect the orderly and efficient transfer of the servicing provisions hereunder or the related Servicing Agreement, as applicable, to the assuming party.

Section 9.03         Representations, Warranties and Covenants of the Master Servicer.

(a)          The Master Servicer hereby represents and warrants to the Depositor, the Securities Administrator (to the extent that the Master Servicer and the Securities Administrator are not the same Person), SPS and the Trustee, for the benefit of the Certificateholders, as of the Closing Date that:

(i)          it is validly existing and in good standing under the laws of the United States of America as a national banking association, and as Master Servicer has full power and authority to transact any and all business contemplated by this Agreement and to execute, deliver and comply with its obligations under the terms of this Agreement, the execution, delivery and performance of which have been duly authorized by all necessary corporate action on the part of the Master Servicer;

(ii)         the execution and delivery of this Agreement by the Master Servicer and its performance and compliance with the terms of this Agreement will not (A) violate the Master Servicer’s charter or bylaws, (B) violate any law or regulation or any administrative decree or order to which it is subject or (C) constitute a default (or an event which, with notice or lapse of time, or both, would constitute a default) under, or result in the breach of, any material contract, agreement or other instrument to which the Master Servicer is a party or by which it is bound or to which any of its assets are subject, which violation, default or breach would materially and adversely affect the Master Servicer’s ability to perform its obligations under this Agreement;

(iii)        this Agreement constitutes, assuming due authorization, execution and delivery hereof by the other respective parties hereto, a legal, valid and binding obligation of the Master Servicer, enforceable against it in accordance with the terms hereof, except as such enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium and other laws affecting the enforcement of creditors’ rights in general, and by general equity principles (regardless of whether such enforcement is considered in a proceeding in equity or at law);

- 119 -

(iv)        the Master Servicer is not in default with respect to any order or decree of any court or any order or regulation of any federal, state, municipal or governmental agency to the extent that any such default would materially and adversely affect its performance hereunder;

(v)         the Master Servicer is not a party to or bound by any agreement or instrument or subject to any charter provision, bylaw or any other corporate restriction or any judgment, order, writ, injunction, decree, law or regulation that may materially and adversely affect its ability as Master Servicer to perform its obligations under this Agreement or that requires the consent of any third person to the execution of this Agreement or the performance by the Master Servicer of its obligations under this Agreement;

(vi)        no litigation is pending or, to the best of the Master Servicer’s knowledge, threatened against the Master Servicer which would prohibit its entering into this Agreement or performing its obligations under this Agreement;

(vii)       the Master Servicer, or an affiliate thereof the primary business of which is the servicing of conventional residential mortgage loans, is a Xxxxxx Mae- or Xxxxxxx Mac-approved seller/servicer;

(viii)      no consent, approval, authorization or order of any court or governmental agency or body is required for the execution, delivery and performance by the Master Servicer of or compliance by the Master Servicer with this Agreement or the consummation of the transactions contemplated by this Agreement, except such consents, approvals, authorizations and orders (if any) as have been obtained; and

(ix)         the consummation of the transactions contemplated by this Agreement are in the ordinary course of business of the Master Servicer.

(b)          It is understood and agreed that the representations and warranties set forth in this Section shall survive the execution and delivery of this Agreement. In addition to any indemnity required pursuant to Section 6.25 hereof, the Master Servicer shall indemnify the Depositor, the Securities Administrator (to the extent that the Master Servicer and the Securities Administrator are not the same Person), SPS and the Trustee and hold them harmless against any loss, damages, penalties, fines, forfeitures, legal fees and related costs, judgments, and other costs and expenses resulting from any claim, demand, defense or assertion based on or grounded upon, or resulting from, a material breach of the Master Servicer’s representations and warranties contained in Section 9.03(a) or any failure by the Master Servicer to deliver any information, report, certification, accountants’ letter or other material when and as required under this Agreement. It is understood and agreed that the enforcement of the obligation of the Master Servicer set forth in this Section to indemnify the Depositor, the Securities Administrator, SPS and the Trustee as provided in this Section 9.03(b) constitutes the sole remedy (other than as set forth in Section 6.14) of the Depositor, the Securities Administrator, SPS and the Trustee, respecting a breach of the foregoing representations and warranties. Such indemnification shall survive any termination of the Master Servicer as Master Servicer hereunder, and any termination of this Agreement.

Any cause of action against the Master Servicer relating to or arising out of the breach of any representations and warranties made in this Section 9.03(b) shall accrue upon discovery of such breach by either the Depositor, the Master Servicer or the Trustee or written notice thereof by any one of such parties to the other parties.

- 120 -

The Master Servicer shall not be responsible for the validity, priority, perfection or sufficiency of the security of the Certificates issued or intended to be issued hereunder.

(c)          The Master Servicer covenants and agrees that it shall not hold or purchase any Certificate if its holding or purchase of such Certificate (or interest therein) would cause the Master Servicer to be required to consolidate any assets of the Trust Fund on its financial statements under U.S. generally accepted accounting principles (“Consolidate” or “Consolidation”). The Master Servicer shall be deemed to have represented by virtue of its purchase or holding of such Certificate (or interest therein) that its holding or purchase of such Certificate (or interest therein) will not cause the Master Servicer to be required to Consolidate any assets of the Trust on its financial statements.

If the Master Servicer's holding or purchase of a Certificate (or interest therein) does in fact cause such Consolidation, then the last preceding transferee that is not required to Consolidate shall be restored, to the extent permitted by law, to all rights and obligations as owner of such Certificate retroactive to the date of such transfer of such Certificate. If the Master Servicer holds or purchases a Certificate (or interest therein) in violation of the restrictions in this Section 9.03(c) and to the extent that the retroactive restoration of the rights of the owner of such Certificate as described in the immediately preceding sentence shall be invalid, illegal or unenforceable, then the Securities Administrator shall have the right, without notice to the owner or any prior owner of such Certificate, to sell such Certificate to a purchaser selected by the Securities Administrator on such terms as the Securities Administrator may choose. The Master Servicer shall promptly endorse and deliver such Certificate in accordance with the instructions of the Securities Administrator. The proceeds of such sale, net of the commissions (which may include commissions payable to the Securities Administrator or its affiliates), expenses and taxes due, if any, shall be remitted by the Securities Administrator to the Master Servicer. The terms and conditions of any sale under this Section 9.03(c) shall be determined in the sole discretion of the Securities Administrator, and the Securities Administrator shall not be liable to any owner of a Certificate as a result of its exercise of such discretion. The Master Servicer shall indemnify and hold harmless the Depositor and the Trust Fund from and against any and all losses, liabilities, claims, costs or expenses incurred by such parties as a result of such holding or purchase by the Master Servicer resulting in a Consolidation.

(d)          The Master Servicer covenants and agrees that it shall not transfer its master servicing rights and duties under this Agreement to an insured depository institution, as such term is defined in the Federal Deposit Insurance Act (an “insured depository institution”, and any such insured depository institution in such capacity, a “master servicer transferee”) unless the Master Servicer shall have received a representation from the master servicer transferee that the acquisition of such master servicing rights and duties will not cause the master servicer transferee to be required to Consolidate any assets of the Trust Fund on its financial statements. Any master servicer transferee shall be deemed to have represented by virtue of its acquisition of such master servicing rights and duties that such acquisition will not cause Consolidation. Any master servicer transferee whose acquisition of such master servicing rights and duties was effected in violation of the restrictions in this Section 9.03(d) shall indemnify and hold harmless the Master Servicer, the Depositor and the Trust Fund from and against any and all losses, liabilities, claims, costs or expenses incurred by such parties as a result of such acquisition.

- 121 -

Section 9.04         Compensation to the Master Servicer.

The Master Servicer shall be entitled to be paid from the Trust Fund, and shall either retain or withdraw from the Distribution Account, (i) its Master Servicing Fee with respect to each Distribution Date, (ii) all amounts necessary to reimburse itself for any previously unreimbursed Advances and Nonrecoverable Advances in accordance with the definition of Available Distribution Amount and (iii) in accordance with the second paragraph of Section 9.01(b), the cost of any enforcement action taken by it under Section 9.01 hereof, including, without limitation, any costs incurred in connection with the termination of a Servicer or Five Oaks, the appointment of a successor servicer or successor owner of the servicing rights with respect to the Five Oaks MSR Mortgage Loans, as applicable, or the transfer and assumption of the servicing by the Master Servicer, which shall not be subject to the limitation set forth in clause (C) of the definition of Available Distribution Amount. The Master Servicer shall be required to pay all expenses incurred by it in connection with its activities hereunder and shall not be entitled to reimbursement therefor except as provided in this Agreement.

Section 9.05         Merger or Consolidation.

Any Person into which the Master Servicer may be merged or consolidated, or any Person resulting from any merger, conversion, other change in form or consolidation to which the Master Servicer shall be a party, or any Person succeeding to the business of the Master Servicer, shall be the successor to the Master Servicer hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or resulting Person to the Master Servicer or any Affiliate thereof whose primary business is the servicing of conventional residential mortgage loans shall be a Person that shall be qualified and approved to service mortgage loans for Xxxxxx Mae or Xxxxxxx Mac and shall have a net worth of not less than $15,000,000.

Section 9.06         Resignation of Master Servicer.

Except as otherwise provided in Sections 9.05 and 9.07 hereof, the Master Servicer shall not resign from the obligations and duties hereby imposed on it unless the Master Servicer’s duties hereunder are no longer permissible under applicable law or are in material conflict by reason of applicable law with any other activities carried on by it and such conflict cannot be cured. Any such determination permitting the resignation of the Master Servicer shall be evidenced by an Opinion of Counsel that shall be Independent to such effect delivered to the Trustee. No such resignation shall become effective until the Trustee shall have assumed, or a successor master servicer shall have been appointed by the Trustee and until such successor shall have assumed, the Master Servicer’s responsibilities and obligations under this Agreement. Notice of such resignation shall be given promptly by the Master Servicer and the Depositor to the Trustee.

If, at any time, the Master Servicer resigns under this Section 9.06, or transfers or assigns its rights and obligations under Section 9.07, or is removed as Master Servicer pursuant to Section 6.14, then at such time Xxxxx Fargo Bank, N.A. also shall resign (and shall be entitled to resign) as Securities Administrator, Paying Agent, Authenticating Agent and Certificate Registrar under this Agreement. In such event, the obligations of each such party shall be assumed by the Trustee or such successor master servicer appointed by the Trustee (subject to the provisions of Section 9.02(a)).

- 122 -

Section 9.07         Assignment or Delegation of Duties by the Master Servicer.

Except as expressly provided herein, the Master Servicer shall not assign or transfer any of its rights, benefits or privileges hereunder to any other Person, or delegate to or subcontract with, or authorize or appoint any other Person to perform any of the duties, covenants or obligations to be performed by the Master Servicer hereunder; provided, however, that the Master Servicer shall have the right with the prior written consent of the Trustee and the Depositor (which consent shall not be unreasonably withheld), to delegate or assign to or subcontract with or authorize or appoint any qualified Person to perform and carry out any duties, covenants or obligations to be performed and carried out by the Master Servicer hereunder. Notice of such permitted assignment shall be given promptly by the Master Servicer to the Depositor and the Trustee. If, pursuant to any provision hereof, the duties of the Master Servicer are transferred to a successor master servicer, the entire amount of the Master Servicing Fee and other compensation payable to the Master Servicer pursuant hereto shall thereafter be payable to such successor master servicer. Such successor master servicer shall also pay the fees of the Securities Administrator, as provided herein, and of the Custodian, as provided in the Custodial Agreement.

Section 9.08         Limitation on Liability of the Master Servicer and Others.

Neither the Master Servicer nor any of the directors, officers, employees or agents of the Master Servicer shall be under any liability to the Trustee or the Certificateholders for any action taken or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect the Master Servicer or any such person against any liability that would otherwise be imposed by reason of willful misfeasance, bad faith or negligence in its performance of its duties or by reason of reckless disregard for its obligations and duties under this Agreement. The Master Servicer and any director, officer, employee or agent of the Master Servicer may rely in good faith on any document of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. The Master Servicer shall be under no obligation to appear in, prosecute or defend any legal action that is not incidental to its duties to master service the Mortgage Loans in accordance with this Agreement and that in its opinion may involve it in any expenses or liability; provided, however, that the Master Servicer may in its sole discretion undertake any such action that it may deem necessary or desirable in respect of this Agreement and the rights and duties of the parties hereto and the interests of the Certificateholders hereunder. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities of the Trust Fund and the Master Servicer shall be entitled to be reimbursed therefor out of the Distribution Account.

Section 9.09         Indemnification; Third-Party Claims.

In addition to any indemnity required pursuant to Section 6.25 hereof, the Master Servicer agrees to indemnify the Depositor, the Securities Administrator (to the extent that the Master Servicer and the Securities Administrator are not the same Person), SPS and the Trustee, and hold them harmless against any and all claims, losses, penalties, fines, forfeitures, legal fees and related costs, judgments, and any other costs, liability, fees and expenses that the Depositor, the Securities Administrator, SPS or the Trustee may sustain as a result of the Master Servicer’s willful misfeasance, bad faith or negligence in the performance of its duties hereunder or by reason of its reckless disregard for its obligations and duties under this Agreement. The Depositor, the Securities Administrator (to the extent that the Master Servicer and the Securities Administrator are not the same Person), SPS and the Trustee shall immediately notify the Master Servicer if a claim is made by a third party with respect to this Agreement or the Mortgage Loans entitling the Depositor, the Securities Administrator (to the extent that the Master Servicer and the Securities Administrator are not the same Person), SPS or the Trustee to indemnification under this Section 9.09, whereupon the Master Servicer shall assume the defense of any such claim and pay all expenses in connection therewith, including counsel fees, and promptly pay, discharge and satisfy any judgment or decree which may be entered against it or them in respect of such claim.

- 123 -

Section 9.10         Master Servicer Fidelity Bond and Master Servicer Errors and Omissions Insurance Policy.

The Master Servicer, at its expense, shall maintain in effect a blanket fidelity bond and an errors and omissions insurance policy, affording coverage with respect to all directors, officers, employees and other Persons acting on such Master Servicer’s behalf, and covering errors and omissions in the performance of the Master Servicer’s obligations hereunder. The errors and omissions insurance policy and the fidelity bond shall be in such form and amount generally acceptable for entities serving as master servicers or trustees.

Article X

ADMINISTRATION AND SERVICING OF MORTGAGE LOANS BY SPS

Section 10.01         Engagement of SPS to Perform Servicing Responsibilities.

The Trustee, for the benefit of the Certificateholders, by execution and delivery of this Agreement, does hereby contract with SPS, subject to the terms of this Agreement, for the servicing of the Mortgage Loans indicated on the Mortgage Loan Schedule attached hereto as being serviced by SPS. SPS shall commence such servicing, and the provisions of this Agreement shall apply to the parties hereto, as of the Closing Date. SPS shall maintain a Servicing File with respect to each Mortgage Loan in order to service such Mortgage Loans pursuant to this Agreement and each Servicing File delivered to SPS shall be held in trust by SPS for the benefit of the Trustee on behalf of the Certifcateholders. The Servicing File retained by SPS pursuant to this Agreement shall be identified in accordance with SPS’s file tracking system to reflect the ownership of the related Mortgage Loan by the Trustee on behalf of the Certifcateholders. SPS shall release from its custody the contents of any Servicing File retained by it only in accordance with this Agreement. For the purposes of this Article X, the term “Mortgage Loan” shall only refer to the Mortgage Loans serviced by SPS pursuant to this Agreement.

Section 10.02         SPS to Service.

SPS, as an independent contractor, shall service and administer the related Mortgage Loans on behalf of Five Oaks as owner of the Servicing Rights with respect to the related Mortgage Loans from and after the Closing Date in accordance with Accepted Servicing Practices, applicable law and this Agreement, and shall have full power and authority, acting alone, to do any and all things in connection with such servicing and administration which SPS may deem necessary or desirable and consistent with the terms of this Agreement and with Accepted Servicing Practices.

SPS is hereby authorized and empowered to work with third-party origination providers to refinance Mortgagors into new mortgage loans, including new mortgage loans with principal balances less than the Stated Principal Balance of the related Mortgage Loan by forgiving a portion of the Stated Principal Balance of the related Mortgage Loan, so long as the Mortgagors are not selected for solicitation based on the inclusion of the related Mortgage Loans on the Mortgage Loan Schedule and such refinancing is consistent with Accepted Servicing Practices and is determined by SPS, in good faith, to likely result in a higher expected recovery of net proceeds taking into account the risks of recovery to the Trustee on behalf of the Certificateholders than continuing to own the Mortgage Loan or other loss mitigation alternatives; provided that such Mortgage Loan is in default or SPS has determined that default is reasonably foreseeable.

- 124 -

Consistent with the terms of this Agreement (including, but not limited to any direction, approval or consent required by Section 2.08 hereof), Accepted Servicing Practices and applicable law, SPS may waive, modify or vary any term of any Mortgage Loan (including entering into a Servicing Modification) or consent to the postponement of strict compliance with any such term or in any manner grant indulgence to any Mortgagor if in SPS’s reasonable and prudent determination the related Mortgagor is in default with respect to such Mortgage Loan or SPS has determined default is foreseeable and such waiver, Servicing Modification, postponement or indulgence is determined by SPS, in good faith, to likely result in a higher expected recovery of net proceeds taking into account the risks of recovery; provided, however, that SPS shall offer a Servicing Modification in accordance with the guidelines of HAMP with respect to any Mortgage Loan that qualifies for such a modification under the guidelines of HAMP and provided that any modification that extends the maturity of any such Mortgage Loan shall in no instance extend the maturity of such Mortgage Loan past the Latest Possible Maturity Date. Any servicer incentive payment payable to SPS in connection with a modification under guidelines of HAMP may be retained by SPS as additional compensation. With respect to any Servicing Modification of a Mortgage Loan where SPS capitalizes Advances and/or Servicing Advances previously made on such Mortgage Loan, SPS shall be entitled to reimburse itself at the time of such Servicing Modification for any Advances and/or a Servicing Advances so capitalized pursuant to Section 10.06(viii) hereof. In addition, in connection with any Servicing Modification, SPS shall be entitled to reimburse itself for Servicing Advances incurred in connection with defending against an ability-to-repay claim by the Mortgagor, at the time of such Servicing Modification in accordance with Section 10.06(x).

Without limiting the generality of the foregoing, SPS shall continue, and is hereby authorized and empowered, to execute and deliver on behalf of itself and the Trustee on behalf of the Certificateholders, all instruments of satisfaction or cancellation, or of partial or full release, discharge or note endorsement and all other comparable instruments, with respect to the Mortgage Loans and the Mortgaged Properties. On the Closing Date and as required by SPS from time to time, the Trustee shall furnish SPS with any limited powers of attorney (in a form agreed to by the Trustee) and other documents necessary or appropriate to enable SPS to carry out its servicing and administrative duties under this Agreement; provided, however, that the Trustee shall not be held liable for any misuse of any such power of attorney or other documents by SPS.

Notwithstanding anything in this Agreement to the contrary (except the provisions of Section 2.08 relating to direction, approval or consent hereof which shall apply), no waiver, modification, variance, postponement of compliance or indulgence made or proposed to be made by SPS in accordance with the foregoing shall require the consent of the Trustee or any other entity.

SPS is authorized and empowered by the Trustee, in its own name or in the name of any Subservicer, when SPS or such Subservicer, as the case may be, believes it is appropriate in its best judgment to cause the removal of any Mortgage Loan from registration on the MERS System, to execute and deliver, on behalf of the Trustee, any and all instruments of assignment and other comparable instruments with respect to such assignment. Any related expenses shall be reimbursable to SPS from the Trust Fund. The Trustee and the Master Servicer shall have no duty to monitor the registration of any Mortgage Loan on the MERS System. Upon the occurrence of a MERS Event with respect to any or all of the Mortgage Loans, SPS shall deregister such Mortgage Loans from MERS and cause MERS to prepare an Assignment of Mortgage within 15 Business Days with respect to each such Mortgage Loan in the name of the Trustee on behalf of the Certificateholders, and any other notice, document or instrument as may be necessary to effect or evidence the transfer of each such related Mortgage to the Trustee on behalf of the Certificateholders. SPS shall notify the Master Servicer and Trustee upon the removal of a Mortgage Loan registered on MERS from the MERS System. SPS shall deliver such Assignment of Mortgage to the Custodian for inclusion in the files of the Custodian.

- 125 -

SPS shall not without the written consent of the Trustee, the Master Servicer and the Depositor, as the case may be: (i) initiate any action, suit or proceeding solely under the name of the Trustee, the Master Servicer and the Depositor, as applicable, without indicating SPS’s representative capacity or (ii) take any action with the intent to cause, and which actually does cause, the Trustee, the Master Servicer and the Depositor to be registered to do business in any state. Notwithstanding the preceding sentence, SPS (subject to any direction, approval or consent required by Section 2.08 hereof) is authorized to initiate foreclosure or similar proceedings in the name of the Trustee on behalf of the Certificateholders without the Trustee’s consent.

In servicing and administering the Mortgage Loans, SPS shall employ procedures (including collection procedures) intended to likely result in a higher expected recovery of net proceeds taking into account the risks of recovery from the Mortgage Loans for the Certificateholders and exercise the same care that it customarily employs and exercises in servicing and administering mortgage loans for its own account giving due consideration to Accepted Servicing Practices and applicable law.

SPS may use Subservicers in connection with the servicing of the Mortgage Loans; provided, however, that any such arrangements shall be consistent with the servicing arrangements contemplated hereunder and SPS shall remain obligated and liable to the Depositor, the Trustee, the Custodian, Master Servicer, the Securities Administrator and the Certificateholders for the servicing and administration of the Mortgage Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such arrangements or by virtue of indemnification from any such Subservicer and to the same extent and under the same terms and conditions as if SPS alone were servicing and administering those Mortgage Loans. All actions of each Subservicer shall be performed as agent of SPS with the same force and effect as if performed directly by SPS.

SPS will furnish, with respect to each Mortgage Loan, in accordance with the Fair Credit Reporting Act and its implementing regulations, accurate and complete information on its borrower credit files to Equifax, Experian and Trans Union Credit Information Company, and any successors thereto, on a monthly basis.

SPS shall promptly forward to the Custodian original documents evidencing an assumption, modification, consolidation or extension of any Mortgage Loan entered into in accordance with this Agreement, provided, however, that SPS shall promptly provide the Custodian with a certified true copy of any such document submitted for recordation, and shall provide the original of any document submitted for recordation or a copy of such document certified by the appropriate public recording office to be a true and complete copy of the original in accordance with Accepted Servicing Practices. No Servicing Modification shall be recorded unless required by applicable law.

SPS shall make Advances and Servicing Advances with respect to each Mortgage Loan in accordance with Accepted Servicing Practices and Section 10.35 of this Agreement, provided that notwithstanding any provision to the contrary, SPS shall not be required to make any Advance or Servicing Advance for which a determination is made by SPS that such Advance or Servicing Advance would constitute a Nonrecoverable Advance.

- 126 -

Section 10.03      Collection of Mortgage Loan Payments.

Continuously from the Closing Date until the principal and interest on all Mortgage Loans are paid in full and all REO Properties acquired with respect thereto have been liquidated, SPS shall proceed diligently to collect all payments due under each Mortgage Loan when the same shall become due and payable and shall follow such collection procedures as it follows with respect to mortgage loans comparable to the Mortgage Loans and held for its own account to the extent such procedures shall be consistent with this Agreement, Accepted Servicing Practices and applicable law. Further, in connection with any Mortgage Loan providing for Escrow Payments by the related Mortgagor, SPS shall take special care in ascertaining and estimating annual ground rents, taxes, assessments, water rates, fire and hazard insurance premiums, mortgage insurance premiums, and all other charges that, as provided in the Mortgage, will become due and payable to the end that the installments payable by the Mortgagors as Escrow Payments will be sufficient to pay such charges as and when they become due and payable.

Section 10.04      Realization Upon Defaulted Mortgage Loans.

(a)          In the event that any payment due under any Mortgage Loan is not paid when the same becomes due and payable, or in the event the Mortgagor fails to perform any other covenant or obligation under the Mortgage Loan and such failure continues beyond any applicable grace period, SPS shall take such action as it shall determine, in good faith, will likely result in a higher expected recovery of net proceeds taking into account the risks of recovery subject to obtaining the required, direction, approval or consent pursuant to Section 2.08 hereof and subject to the REMIC Provisions, a Servicing Modification, assumption, forbearance, extension, short sale, short refinancing, third party sale, deed-in-lieu transaction and, if the mortgagor is unresponsive, acquiring title to the Mortgaged Property through foreclosure as set forth in Section 10.14 hereof. SPS shall use its best efforts, consistent with Accepted Servicing Practices, applicable law and the procedures that SPS would use in servicing loans for its own account, to foreclose upon or otherwise comparably convert the ownership of each Mortgaged Property for which the Mortgage Loan is and continues to be in default and as to which no satisfactory arrangements can be made for collection of delinquent payments pursuant to Section 10.02 and the first sentence of this Section 10.04. SPS shall use its best efforts to realize upon defaulted Mortgage Loans in such a manner as it determines in good faith, will likely result in a higher expected recovery of net proceeds taking into account the risks of recovery, including, among other things, the timing of foreclosure proceedings. The foregoing is subject to the provisions that, in any case in which Mortgaged Property shall have suffered damage, SPS shall not be required to expend its own funds toward the restoration of such property unless it shall determine in its discretion (i) that such restoration will increase the proceeds of liquidation of the related Mortgage Loan after reimbursement to itself for such expenses, and (ii) that such expenses will be recoverable by SPS through Liquidation Proceeds from the related Mortgaged Property as contemplated in Section 10.06. In connection therewith, SPS shall be responsible for all costs and expenses incurred by it in any such foreclosure or collection proceedings; provided, however, that it shall be entitled to reimbursement thereof as contemplated in Section 10.06.

(b)          Notwithstanding the foregoing provisions of this Section 10.04, with respect to any Mortgage Loan as to which SPS has received actual notice of, or has actual knowledge of, the presence of any toxic or hazardous substance on the related Mortgaged Property SPS shall not (i) cause the Trustee on behalf of the Certificateholders to obtain title to such Mortgaged Property as a result of or in lieu of foreclosure or otherwise or (ii) otherwise cause the Trustee on behalf of the Certificateholders to acquire possession of, or take any other action with respect to, such Mortgaged Property if, as a result of any such action, the Trustee, the Certificateholders or the Depositor would be considered to hold title to, to be a mortgagee-in-possession of, or to be an owner or operator of such Mortgaged Property within the meaning of the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended from time to time, or any comparable law, unless SPS has also previously determined, based on its reasonable judgment and an environmental report prepared by a Person who regularly conducts environmental audits using customary industry standards, that:

- 127 -

(i)          such Mortgaged Property is in compliance with applicable environmental laws or, if not, that it would be in the best economic interest of the Trustee on behalf of the Certificateholders to take such actions as are necessary to bring the Mortgaged Property into compliance therewith; and

(ii)         there are no circumstances present at such Mortgaged Property relating to the use, management or disposal of any hazardous substances, hazardous materials, hazardous wastes, or petroleum-based materials for which investigation, testing, monitoring, containment, clean-up or remediation could be required under any federal, state or local law or regulation, or that if any such materials are present for which such action could be required, that it would be advisable considering the economic interest of the Certificateholders (in the aggregate) to take such actions with respect to the affected Mortgaged Property.

SPS shall not be required to obtain an environmental report of such Mortgaged Property unless the Mortgagor has consented or agreed to provide access to such Mortgaged Property for such report. The cost of the environmental audit report contemplated by this Section 10.04 shall be advanced by SPS, subject to SPS’s right to be reimbursed therefor from the Collection Account as provided in Section 10.06(iv).

If SPS determines, as described above, that it is advisable considering the economic interest of the Certificateholders (in the aggregate) to take such actions as are necessary to bring any such Mortgaged Property into compliance with applicable environmental laws, or to take such action with respect to the containment, clean-up or remediation of hazardous substances, hazardous materials, hazardous wastes, or petroleum-based materials affecting any such Mortgaged Property, then SPS shall take such action, consistent with Accepted Servicing Practices and applicable law, as it deems to be advisable considering the economic interest of the Certificateholders (in the aggregate). The cost of any such compliance, containment, cleanup or remediation shall be advanced by SPS, subject to SPS’s right to be reimbursed therefor from the Collection Account as provided in Section 10.06(iv).

(c)          Proceeds received in connection with any Final Recovery Determination, including any recovery of Liquidation Proceeds in respect of any Mortgage Loan, will be applied in the following order of priority (to the extent permitted by applicable law): first, to reimburse SPS for any related unreimbursed Servicing Fees, Advances or Servicing Advances, pursuant to Section 10.06(ii); second, with respect to any Mortgage Loan, to accrued and unpaid interest on the Mortgage Loan, to the date of the Final Recovery Determination, or to the Due Date prior to the Servicer Remittance Date on which such amounts are to be distributed if not in connection with a Final Recovery Determination; and third, with respect to any Mortgage Loan, as a recovery of principal of such Mortgage Loan. SPS shall maintain records, prepared by an officer of SPS, of each Final Recovery Determination.

Section 10.05         Establishment of Collection Account; Deposits in Collection Account.

SPS shall segregate and hold all funds collected and received pursuant to each Mortgage Loan separate and apart from any of its own funds and general assets and shall establish and maintain on behalf of, and as an agent of, the Issuer, a segregated Collection Account, which shall be an Eligible Account, entitled “Select Portfolio Servicing, Inc., in trust for Christiana Trust, a division of Wilmington Savings Fund Society, FSB, as Trustee for the benefit of the Holders of CSMC Trust 2014-OAK1 Mortgage Pass-Through Certificates, Collection Account.” SPS shall deposit in the Collection Account on a daily basis within two (2) Business Days of identification, and retain therein the following payments and collections received by it subsequent to the Cut-off Date:

(iv)        all Advances made by SPS pursuant to Section 10.35;

(v)         the amount of any Servicer Compensating Interest Payment for SPS for the related Prepayment Period (such deposit shall be made from SPS’s own funds, without reimbursement therefor);

(vi)        any amounts required to be deposited by SPS pursuant to Section 10.12 in connection with the deductible clause in any blanket hazard insurance policy. Such deposit shall be made from SPS’s own funds, without reimbursement therefor; and

(vii)       any other amounts required to be deposited hereunder.

The deposits pursuant to clauses (ii) or (iii) may, at SPS’s option, be net of the related Servicing Fee. The foregoing requirements for deposit in the Collection Account shall be exclusive, it being understood and agreed that, without limiting the generality of the foregoing, payments in the nature of late payment charges, assumption fees, servicer incentive fees received by SPS in connection with a Servicing Modification in accordance with the guidelines of HAMP and other ancillary income to the extent permitted by Section 10.21, need not be deposited by SPS in the Collection Account. Any interest or earnings on funds deposited in the Collection Account by the depository institution shall accrue to the benefit of SPS and SPS shall be entitled to retain and withdraw such interest from the Collection Account pursuant to Section 10.06(iii). SPS shall give notice to the Securities Administrator, Trustee and the Master Servicer of the location of the Collection Account when established and prior to any change thereof in accordance with Section 10.10 hereof.

Funds on deposit in the Collection Account shall either (i) remain uninvested or (ii) be invested in Eligible Investments, which Eligible Investments shall mature or be subject to redemption or withdrawal on or prior to the next occurring Servicer Remittance Date. If such funds are deposited in Eligible Investments, any and all investment earnings from any such Eligible Investments shall be for the benefit of SPS, and the risk of loss of moneys required to be remitted to the Securities Administrator for deposit in the Distribution Account resulting from such investments shall be borne by and be the risk of SPS. The amount of any losses realized in the Collection Account in respect of any such Eligible Investments shall promptly be deposited by SPS from its own funds in the Collection Account.

Section 10.06         Permitted Withdrawals From the Collection Account.

SPS may, from time to time, withdraw from amounts on deposit in the Collection Account for the following purposes:

- 129 -

(i)          to make distributions to the Securities Administrator for deposit to the Distribution Account in the amounts and in the manner provided for in Section 10.15;

(ii)         to the extent not previously reimbursed, to reimburse SPS for unreimbursed Advances or Servicing Advances made by SPS, SPS’s right to reimburse itself pursuant to this subclause (ii) with respect to any Mortgage Loan being limited to related Liquidation Proceeds and such other amounts as may be collected by SPS from the Mortgagor or otherwise relating to the Mortgage Loan;

(iii)        to pay to itself pursuant to Section 10.21 as servicing compensation (A) any interest earned on funds in the Collection Account (all such interest to be withdrawn monthly not later than each Servicer Remittance Date), and (B) the Servicing Fee for each Mortgage Loan (to the extent not retained by SPS);

(viii)      to reimburse itself for any Capitalization Reimbursement Amounts at the time of the modification of any Mortgage Loan to the extent such Capitalization Reimbursement Amounts were previously remitted by SPS as part of an Advance or a Servicing Advance and not previously reimbursed; provided, that such reimbursements shall only be made out of the principal portion of collections on the Mortgage Loans;

(ix)         to pay itself any Prepayment Interest Excess; provided that SPS shall only be entitled to any Prepayment Interest Excess with respect to any Mortgage Loan and any Distribution Date if the related Principal Prepayment is deposited to the related Collection Account pursuant to Section 10.05 hereof in the same month as such Principal Prepayment is made, to be included with distributions on such Distribution Date;

(x)          to reimburse itself for any Servicing Advances incurred in connection with defending against an ability-to-repay claim by the Mortgagor at the time of a Servicing Modification to the related Mortgage Loan; and

(xi)         to reimburse SPS for expenses incurred by or reimbursable to SPS pursuant to Section 10.32.

In the case of each such reimbursement set forth above and payment of the servicing compensation, SPS’s right thereto shall be prior to the rights of the Certificateholders or any other Person.

- 130 -

SPS shall keep and maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any withdrawal from the Collection Account pursuant to such subclauses (ii), (iii), (iv), (vii) and (viii) above.

Section 10.07         Deposits in Escrow Account.

SPS shall segregate and hold all funds collected and received pursuant to each Mortgage Loan which constitute Escrow Payments separate and apart from any of its own funds and general assets and shall establish and maintain on behalf of, and as an agent of, the Trustee on behalf of the Certificateholders, a segregated Escrow Account, which shall be an Eligible Account, entitled “Select Portfolio Servicing, Inc., in trust for Christiana Trust, a division of Wilmington Savings Fund Society, FSB, as Trustee for the benefit of the Holders of CSMC Trust 2014-OAK1 Mortgage Pass-Through Certificates, Escrow Account.”

SPS shall deposit in the Escrow Account on a daily basis within two (2) Business Days of identification, and retain therein, all Escrow Payments collected on account of the Mortgage Loans, for the purpose of effecting timely payment of any such items as required under the terms of this Agreement. SPS shall make withdrawals therefrom only to effect such payments as are required under this Agreement, and for such other purposes as shall be as set forth in, or in accordance with, Section 10.08. SPS shall be entitled to retain any interest paid on funds deposited in the Escrow Account by the depository institution other than interest on escrowed funds required by applicable law to be paid to the Mortgagor and, to the extent required by applicable law, SPS shall pay interest on escrowed funds to the Mortgagor notwithstanding that the Escrow Account is non-interest bearing or that interest paid thereon is insufficient for such purposes.

Section 10.08         Permitted Withdrawals From Escrow Account.

Withdrawals from the Escrow Account may be made by SPS (i) to effect timely payments of ground rents, taxes, assessments, water rates, hazard insurance premiums and comparable items, (ii) to reimburse SPS for any Advance or Servicing Advances made by SPS with respect to a related Mortgage Loan but only from amounts received on the related Mortgage Loan which represent late payments or collections of Escrow Payments thereunder, (iii) to refund to the Mortgagor any funds as may be determined to be overages, (iv) for transfer to the Collection Account in accordance with the terms of this Agreement, (v) for application to restoration or repair of the Mortgaged Property, (vi) to pay to SPS, or to the Mortgagor to the extent required by applicable law, any interest paid on the funds deposited in the Escrow Account, or (vii) to withdraw any amount deposited therein in error.

Section 10.09         Payment of Taxes, Insurance and Other Charges; Collections Thereunder.

With respect to each Mortgage Loan, SPS shall maintain accurate records reflecting the status of fire and hazard insurance coverage and, to the extent the Mortgage provides for Escrow Payments, shall obtain, from time to time, all bills for the payment of such charges, including insurance renewal premiums and shall effect payment thereof prior to the applicable penalty or termination date, employing for such purpose deposits of the Mortgagor in the Escrow Account which shall have been estimated and accumulated by SPS in amounts sufficient for such purposes, as allowed under the terms of the Mortgage and applicable law. To the extent that the Mortgage does not provide for Escrow Payments, SPS shall use commercially reasonable efforts to determine that any such payments are made by the Mortgagor, and if SPS has knowledge that any such payments have not been made by the Mortgagor, SPS shall make a Servicing Advance for payment of property taxes to the extent needed to prevent the related Mortgaged Property from being subject to a tax sale unless SPS shall deem such Servicing Advance to be nonrecoverable, in accordance with Accepted Servicing Practices.

- 131 -

Section 10.10         Transfer of Accounts.

SPS may transfer the Collection Account or the Escrow Account to a different depository institution from time to time. In any case, each of the Collection Account and the Escrow Account shall at all times be maintained as an Eligible Account. SPS shall give notice to the Trustee, the Master Servicer and the Securities Administrator of any proposed change of location of the Collection Account or Escrow Account, as applicable, not later than thirty (30) days after and not more that thirty (30) days prior to any change thereof.

Section 10.11         Maintenance of Hazard Insurance.

SPS shall cause to be maintained for each Mortgage Loan with sufficient equity (as determined by SPS in accordance with Accepted Servicing Practices, including its net present value model), fire and hazard insurance with extended coverage as is customary in the area where the related Mortgaged Property is located in an amount which is at least equal to the lesser of (i) the full insurable value of such Mortgaged Property or (ii) the outstanding principal balance of such Mortgage Loan, in each case in an amount not less than such amount as is necessary to prevent the Mortgagor and/or the Mortgagee from becoming a co-insurer; provided, however, if the Mortgagor allows such coverage to lapse, SPS shall procure coverage equal to the higher of (x) the last known coverage amount, if available, or (y) the Stated Principal Balance.

With respect to each Mortgage Loan with sufficient equity (as determined by SPS in accordance with Accepted Servicing Practices, including its net present value model), if such Mortgaged Property is in an area identified in the Federal Register by the Federal Emergency Management Agency as having special flood hazards and such flood insurance has been made available, SPS will cause to be maintained a flood insurance policy meeting the requirements of the current guidelines of the Federal Insurance Administration with a generally acceptable insurance carrier, in an amount representing coverage not less than the least of (i) the Stated Principal Balance of the Mortgage Loan, (ii) the full insurable value of the related Mortgaged Property or (iii) the maximum amount of insurance which is available under the National Flood Insurance Act of 1968. Pursuant to Section 10.05, any amounts collected by SPS under any such policies other than amounts to be deposited in the Escrow Account and applied to the restoration or repair of the Mortgaged Property, or released to the Mortgagor in accordance with SPS’s normal servicing procedures, shall be deposited in the Collection Account, subject to withdrawal pursuant to Section 10.06. Except in connection with a Servicing Modification, any cost incurred by SPS in maintaining any such insurance shall not, for the purpose of calculating distributions to the Securities Administrator, be added to the Stated Principal Balance of the related Mortgage Loan, notwithstanding that the terms of such Mortgage Loan so permit. SPS shall not be required to maintain any such insurance if the related Servicing Advance therefor would be a Nonrecoverable Advance. It is understood and agreed that no earthquake or other additional insurance need be required by SPS of the Mortgagor or property acquired in respect of a Mortgage Loan, other than pursuant to such applicable laws and regulations as shall at any time be in force and as shall require such additional insurance. All such policies shall be endorsed with standard mortgagee clauses with loss payable to SPS and shall provide for at least thirty (30) days prior written notice of any cancellation, reduction in the amount of, or material change in, coverage to SPS. SPS shall not interfere with the Mortgagor’s freedom of choice in selecting either his insurance carrier or agent; provided, however, that SPS shall not accept any such insurance policies from insurance companies unless such companies are Qualified Insurers.

- 132 -

Section 10.12         Maintenance of Blanket Hazard Insurance Policy.

In the event that SPS shall obtain and maintain a blanket policy issued by a Qualified Insurer that has a rating in Best’s Key Rating Guide of A:VI or is acceptable to prudent mortgage servicers insuring against hazard losses on all of the Mortgaged Properties, then, to the extent such policy provides coverage in an amount equal to the amount required pursuant to Section 10.11 and otherwise complies with all other requirements of Section 10.11, SPS shall conclusively be deemed to have satisfied its obligations as set forth in Section 10.11, it being understood and agreed that such policy may contain a deductible clause. In connection with its activities as servicer of the Mortgage Loans, SPS agrees to prepare and present, on behalf of the Certificateholders, claims under any such blanket policy in a timely fashion in accordance with the terms of such policy. Upon request of the Trustee or Master Servicer, SPS shall cause to be delivered to the Trustee or Master Servicer, as applicable, a certified true copy of such policy or a certificate evidencing such policy and a statement from the insurer thereunder that such policy shall in no event be terminated or materially modified without thirty (30) days prior written notice to the Trustee and Master Servicer.

Section 10.13         Fidelity Bond, Errors and Omissions Insurance.

SPS shall maintain, at its own expense, a blanket fidelity bond and an errors and omissions insurance policy, with broad coverage with responsible companies that would meet the requirements of Xxxxxxx Mac on all officers, employees or other persons acting in any capacity with regard to the Mortgage Loans to handle funds, money, documents and papers relating to the Mortgage Loans. Such fidelity bond and errors and omissions insurance shall protect and insure SPS against losses, including forgery, theft, embezzlement, fraud, errors and omissions and negligent acts of such persons. Such fidelity bond shall also protect and insure SPS against losses in connection with the failure to maintain any Insurance Policies required pursuant to this Agreement. No provision of this Section 3.12 requiring the fidelity bond and errors and omissions insurance shall diminish or relieve SPS from its duties and obligations as set forth in this Agreement. The minimum coverage under any such bond and insurance policy shall be at least equal to the corresponding amounts required by Xxxxxxx Mac in the Xxxxxxx Xxx Xxxxxxx’ and Servicers’ Guide. Upon request of the Trustee or Master Servicer, SPS shall cause to be delivered to the Trustee or Master Servicer, as applicable, a certified true copy of the fidelity bond and errors and omissions insurance certificate evidencing the same and a statement from the surety and the insurer that such fidelity bond or insurance policy may not be terminated or materially modified without thirty (30) days’ prior written notice to the Trustee and Master Servicer.

Section 10.14         Title, Management and Disposition of REO Property.

In the event that title to any Mortgaged Property is acquired in foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale shall be issued in the name of the Trustee, on behalf of the and Certificateholders of the CSMC Trust 2014-OAK1, or its designee. The Trustee’s name shall be placed on the title to such REO Property solely as the Trustee hereunder and not in its individual capacity. SPS shall ensure that the title to such REO Property references this Agreement and the Trustee’s capacity hereunder.

- 133 -

SPS shall either itself or through an agent selected by SPS, conserve, protect and operate each REO Property (and may temporarily rent the same) in the same manner that it conserves, protects and operates other foreclosed property for its own account, and in the same manner that similar property in the same locality as the REO Property is conserved, protected and operated consistent with Accepted Servicing Practices and applicable law. SPS shall cause each REO Property to be inspected promptly upon the acquisition of title thereto and shall cause each REO Property to be inspected at least quarterly thereafter. SPS shall make or cause to be made a written report of each such inspection. Such reports shall be retained in the Servicing File. Consistent with the terms of this Agreement (including, but not limited to any direction, approval or consent required pursuant to Section 2.08), SPS shall use its best efforts to dispose of the REO Property as soon as possible, subject to its obligation to conserve, protect and operate each such REO Property solely for the purpose resulting in a higher expected recovery of net proceeds. Pursuant to its efforts to sell such property, SPS shall either itself or through an agent selected by SPS, protect and conserve such property in the same manner and to such an extent as is customary in the locality where such property is located and consistent with applicable law. Additionally, SPS shall perform any tax withholding and reporting required by the Code.

Each REO disposition shall be carried out by SPS at such price and upon such terms and conditions as SPS determines in good faith, to likely result in a higher expected recovery of net proceeds taking into account the risks of recovery.

Section 10.15         Remittances.

On each Servicer Remittance Date prior to the termination of this Agreement, SPS shall remit to the Securities Administrator for deposit to the Distribution Account no later than 3:00 P.M. New York city time all amounts credited to the Collection Account with respect to the related Collection Period, net of charges against or withdrawals from the Collection Account pursuant to Section 10.06. With respect to any remittance received by the Master Servicer after the Business Day on which such payment was due, SPS shall pay to the Master Servicer interest on any such late payment at an annual rate equal to one-month LIBOR (as published in the Wall Street Journal) plus 200 basis points, but in no event greater than the maximum amount permitted by applicable law. Such interest shall be paid by SPS to the Master Servicer on the date such late payment is made and shall cover the period commencing with the Business Day on which such payment was due and ending with and including the day prior to the Business Day on which such payment is made, both inclusive. Such interest shall be remitted along with such late payment.

All distributions required to be made to the Securities Administrator under this Agreement shall be on a scheduled/scheduled basis and made to the following wire account:

- 134 -

Section 10.17         Statements to the Securities Administrator.

Upon request, SPS shall forward to the Securities Administrator and the Master Servicer (or a designee thereof) a statement prepared by SPS setting forth the status of the Collection Account as of the end of the Collection Period preceding the most recent Servicer Remittance Date and showing, for the period covered by such statement, the aggregate amount of deposits into and withdrawals from the Collection Account of each category of deposit specified in Section 10.05 and each category of withdrawal specified in Section 10.06.

SPS shall prepare or cause to be prepared and file or cause to be filed any and all tax returns, information statements or other filings that SPS is required to deliver to any governmental taxing authority or to the Securities Administrator, the Master Servicer and each successor in interest pursuant to any applicable law with respect to the Mortgage Loans arising after the Closing Date. In addition, SPS shall provide, not more than 60 days after the end of each calendar year, the Securities Administrator with such information reasonably available to SPS arising after the Closing Date concerning the Mortgage Loans as is necessary for such Party to prepare any income tax return or report as any such Party may reasonably request from time to time. SPS shall not be responsible for any REMIC tax returns or tax returns of the Trust Fund.

Section 10.18         Compliance with the Homes Act.

SPS, on behalf of the Certificateholders, shall prepare and distribute a Section 404 Notice to each Mortgagor within thirty (30) days of the Closing Date in connection with the sale of the Mortgage Loans from the Seller to the Depositor. Each such Section 404 Notice shall conform to the form of notice attached hereto as Exhibit K or in another form reasonably acceptable to SPS, subject to any changes necessitated by regulatory guidance. SPS shall pay all costs associated with the distribution of such Section 404 Notice, and the Seller shall reimburse SPS for such costs. SPS shall promptly send written confirmation to the Trustee, the Master Servicer and the Securities Administrator upon the completion of the distribution of such Section 404 Notices.

Section 10.19         Assumption Agreements.

SPS shall, to the extent it has knowledge of any conveyance or prospective conveyance by any Mortgagor of the Mortgaged Property (whether by absolute conveyance or by contract of sale, and whether or not the Mortgagor remains or is to remain liable under the Mortgage Note and/or the Mortgage), exercise its rights to accelerate the maturity of such Mortgage Loan under any “due-on-sale” clause applicable thereto; provided, however, that SPS shall not exercise any such rights if prohibited by applicable law from doing so. If SPS reasonably believes it is unable under applicable law to enforce such “due-on-sale” clause, SPS shall enter into an assumption agreement with the person to whom the Mortgaged Property has been conveyed or is proposed to be conveyed, pursuant to which such person becomes liable under the Mortgage Note and, to the extent permitted by applicable law, the Mortgagor remains liable thereon. Where an assumption is allowed pursuant to this Section 10.19, SPS is authorized to enter into a substitution of liability agreement with the person to whom the Mortgaged Property has been conveyed or is proposed to be conveyed pursuant to which the original Mortgagor is released from liability and such Person is substituted as Mortgagor and becomes liable under the related Mortgage Note. Any such substitution of liability agreement shall be in lieu of an assumption agreement.

- 135 -

In connection with any such assumption or substitution of liability, SPS shall follow the underwriting practices and procedures of prudent mortgage lenders in the state in which the related Mortgaged Property is located. With respect to an assumption or substitution of liability, the Mortgage Rate, the amount of the Scheduled Payment, and the final maturity date of such Mortgage Note may not be changed. The original of any such substitution of liability or assumption agreement shall be added to the related Trustee Mortgage File and shall, for all purposes, be considered a part of such Trustee Mortgage File to the same extent as all other documents and instruments constituting a part thereof. Any fee collected by SPS for entering into an assumption or substitution of liability agreement shall be for the benefit of SPS as part of its servicing compensation.

Notwithstanding the foregoing paragraphs of this Section or any other provision of this Agreement, SPS shall not be deemed to be in default, breach or any other violation of its obligations hereunder by reason of any assumption of a Mortgage Loan by operation of law or any assumption which SPS may be restricted by applicable law from preventing, for any reason whatsoever. For purposes of this Section 1019, the term “assumption” is deemed to also include a sale of the Mortgaged Property subject to the Mortgage that is not accompanied by an assumption or substitution of liability agreement.

Section 10.20         Satisfaction of Mortgages and Release of Trustee Mortgage Files.

Upon the payment in full of any Mortgage Loan, or the receipt by SPS of a notification that payment in full will be escrowed in a manner customary for such purposes, SPS shall request execution of any document necessary to satisfy the Mortgage Loan and delivery to it of the Trustee Mortgage File held by the Custodian by delivery to the Custodian of a Request for Release. Upon receipt of such certification and request, the Custodian shall promptly release the related Trustee Mortgage File to SPS and SPS shall prepare and process any satisfaction or release. Any such reasonable expense incurred in connection with any instrument of satisfaction or deed of reconveyance shall be deemed a Servicing Advance.

From time to time and as appropriate for servicing or foreclosure of any Mortgage Loan, the Custodian shall, pursuant to the Custodial Agreement, upon request of SPS and delivery to the Custodian of a request for release, a form of which is attached hereto as Exhibit I (a “Request for Release”), signed by a Servicing Officer, release the Trustee Mortgage File or requested portion thereof held by the Custodian to SPS. SPS shall return the related Trustee Mortgage File to the Custodian when the need therefor by SPS no longer exists, unless the Mortgage Loan has been liquidated or sold and the Liquidation Proceeds relating to the Mortgage Loan have been deposited in the Collection Account or the Trustee Mortgage File or such document has been delivered to an attorney, or to a public trustee or other public official as required by applicable law, for purposes of initiating or pursuing legal action or other proceedings for the foreclosure of the Mortgaged Property either judicially or non-judicially. Upon the Custodian’s receipt of the Request for Release indicating that such Mortgage Loan was liquidated, the Trustee Mortgage File shall be released by the Custodian to SPS, and the Custodian shall have no further responsibility with regard to such Trustee Mortgage File.

Section 10.21         Servicing Compensation.

As compensation for its services hereunder, SPS shall be entitled to withdraw from the Collection Account or to retain from collections on the Mortgage Loans the amounts provided for as SPS’s Servicing Fee. Additional servicing compensation in the form of assumption fees, as provided in Section 10.19, late payment charges, servicer incentive fees received by SPS in connection with a Servicing Modification in accordance with the guidelines of HAMP and similar ancillary servicing compensation shall be retained by SPS to the extent not required to be deposited in the Collection Account, pursuant to Section 10.05. In addition, SPS shall be entitled to investment earnings from Eligible Investments of funds on deposit in the Collection Account pursuant to Section 10.05 and the Escrow Account pursuant to Section 10.08. SPS shall be required to pay all expenses incurred by it in connection with its servicing activities hereunder and shall not be entitled to reimbursement therefor except as specifically provided for herein. Upon the termination of SPS and any transfer of servicing hereunder, SPS is entitled to reimbursement for any outstanding and unreimbursed Servicing Fees, Advances and Servicing Advances; provided, that any such amounts shall only be payable to SPS in accordance with and to the extent provided in this Agreement. SPS shall be entitled to any Prepayment Interest Excess as additional servicing compensation.

- 136 -

Section 10.22       Access to Certain Documentation; No Certificateholder or Certificate Owner Access to Mortgage Loan Documentation or Records.

SPS shall provide to the Office of the Comptroller of the Currency, the FDIC and any other federal or state banking or insurance regulatory authority that may exercise authority over the Trustee, the Master Servicer or the Securities Administrator by applicable laws and regulations access to all records and documentation in its possession regarding the Mortgage Loans. Such access shall be afforded without charge, but only upon reasonable request and during normal business hours at the offices of SPS.

In addition, SPS shall provide access to all records and documentation regarding the Mortgage Loans to the Trustee, the Master Servicer and the Securities Administrator without charge, upon reasonable request during normal business hours at the offices of SPS; provided, however, none of SPS, Trustee, the Master Servicer or the Securities Administrator shall provide access to the records and documentation regarding the Mortgage Loans to any Certificateholder or Certificate Owner or any party acting on behalf of any Certificateholder or Certificate Owner.

SPS shall provide to the Trustee, the Master Servicer, the Securities Administrator and the Custodian a list of Servicing Officers on the Closing Date and shall update such list and deliver an updated list to the Trustee, the Master Servicer, the Securities Administrator and the Custodian as necessary.

Section 10.23        Reports and Returns to be Filed by SPS.

SPS shall file information reports with respect to the receipt of mortgage interest received in a trade or business, reports of foreclosures and abandonments of any Mortgaged Property and information returns relating to cancellation of indebtedness income with respect to any Mortgaged Property as required by Sections 6050H, 6050J and 6050P of the Code for the period following the Closing Date. Such reports shall be in form and substance sufficient to meet the reporting requirements imposed by such Sections 6050H, 6050J and 6050P of the Code.

- 137 -

Section 10.24         Sub-Servicing Agreements Between SPS and Subservicers.

SPS, as servicer, may arrange for the subservicing of any Mortgage Loan by a Subservicer pursuant to a Sub-Servicing Agreement; provided, that such sub-servicing arrangement and the terms of the related Sub-Servicing Agreement must provide for the servicing of such Mortgage Loans in a manner consistent with the servicing arrangements contemplated hereunder; provided, further, that any fees or expenses of such Subservicer shall be payable solely by SPS and shall not result in any increase of the Servicing Fee payable to SPS. Each Subservicer shall be (i) authorized to transact business in the state or states where the related Mortgaged Properties it is to service are situated, if and to the extent required by law applicable to the Subservicer to enable the Subservicer to perform its obligations hereunder and under the Sub-Servicing Agreement and (ii) a Xxxxxxx Mac approved mortgage servicer. Notwithstanding the provisions of any Sub-Servicing Agreement, any of the provisions of this Agreement relating to agreements or arrangements between SPS or a Subservicer or reference to actions taken through SPS or otherwise, SPS shall remain obligated and liable hereunder for the servicing and administration of the Mortgage Loans in accordance with the provisions of this Agreement without diminution of such obligation or liability by virtue of such Sub-Servicing Agreements or arrangements or by virtue of indemnification from the Subservicer and to the same extent and under the same terms and conditions as if SPS alone were servicing and administering the Mortgage Loans. Every Sub-Servicing Agreement entered into by SPS shall contain a provision giving the successor servicer the option to terminate such agreement in the event a successor servicer is appointed. All actions of each Subservicer performed pursuant to the related Sub-Servicing Agreement shall be performed as an agent of SPS with the same force and effect as if performed directly by SPS.

For purposes of this Agreement, SPS shall be deemed to have received any collections, recoveries or payments with respect to the Mortgage Loans that are received by a Subservicer regardless of whether such payments are remitted by the Subservicer to SPS

Section 10.25         Successor Subservicers.

Any Sub-Servicing Agreement shall provide that SPS shall be entitled to terminate any Sub-Servicing Agreement and to either itself directly service the related Mortgage Loans or enter into a Sub-Servicing Agreement with a successor Subservicer which qualifies under Section 10.24. Any Sub-Servicing Agreement shall include the provision that such agreement may be immediately terminated by any successor to SPS without fee, in accordance with the terms of this Agreement, in the event that SPS (or any successor to SPS) shall, for any reason, no longer be the servicer of the related Mortgage Loans (including termination due to a SPS Event of Default). Any costs incurred by a successor Servicer in terminating a Sub-Servicing Agreement entered into by a terminated Servicer and the transfer of servicing in connection therewith shall be reimbursable to the successor Servicer as Servicing Transfer Costs as provided in Section 9.01.

Section 10.26         No Contractual Relationship Between Subservicer and the Trustee and Master Servicer.

Any Sub-Servicing Agreement and any other transactions or services relating to the Mortgage Loans involving a Subservicer shall be deemed to be between the Subservicer and SPS alone and neither the Trustee nor the Master Servicer shall be deemed a party thereto and shall have no claims, rights, obligations, duties or liabilities with respect to any Subservicer except as set forth in Section 10.24.

Section 10.27         Assumption or Termination of Sub-Servicing Agreement by Successor Servicer.

In connection with the assumption of the responsibilities, duties and liabilities and of the authority, power and rights of SPS hereunder by a successor Servicer pursuant to Section 10.34 of this Agreement, it is understood and agreed that SPS’s rights and obligations under any Sub-Servicing Agreement then in force between SPS and a Subservicer shall be assumed simultaneously by such successor Servicer without act or deed on the part of such successor servicer; provided, however, that any successor Servicer may terminate the Subservicer.

SPS shall, upon the reasonable request of the Master Servicer, but at SPS’s own expense, deliver to the assuming party documents and records relating to each Sub-Servicing Agreement and an accounting of amounts collected and held by it and otherwise use its best efforts to effect the orderly and efficient transfer of the Sub-Servicing Agreements to the assuming party.

SPS hereby represents and warrants to the Trustee, for the benefit of the Certificateholders, and to the Master Servicer, the Depositor and the Securities Administrator, as of the Closing Date or such other date as is specified, that:

(i)          SPS is duly organized, validly existing and in good standing as a corporation under the laws of the State of Utah. SPS has all licenses necessary to carry out its business as now being conducted, and is licensed and qualified to transact business in and is in good standing under the laws of each state in which any Mortgaged Property is located or is otherwise exempt under applicable law from such licensing or qualification or is otherwise not required under applicable law to effect such licensing or qualification and no demand for such licensing or qualification has been made upon SPS by any such state, and in any event SPS is in compliance with the laws of any such state, to the extent such laws are applicable to SPS, to the extent necessary to ensure the servicing of the Mortgage Loans in accordance with the terms of this Agreement. No licenses or approvals obtained by SPS have been suspended or revoked by any court, administrative agency, arbitrator or governmental body and no proceedings are pending which could reasonably be expected to result in such suspension or revocation;

(ii)         SPS has duly authorized the execution, delivery and performance of this Agreement, has duly executed and delivered this Agreement, and this Agreement, assuming due authorization, execution and delivery by the Depositor, the Master Servicer, the Securities Administrator and the Trustee constitutes a legal, valid and binding obligation of SPS, enforceable against it in accordance with its terms except as the enforceability thereof may be limited by bankruptcy, insolvency or reorganization;

(iii)        The execution and delivery of this Agreement by SPS and the performance of and compliance with the terms of this Agreement will not violate SPS’s formation documents or constitute a default under or result in a breach or acceleration of, any material contract, agreement or other instrument to which SPS is a party or which may be applicable to SPS or its assets;

(iv)        SPS is not in violation of, and the execution and delivery of this Agreement by SPS and its performance and compliance with the terms of this Agreement will not constitute a violation with respect to, any order or decree of any court or any order or regulation of any federal, state, municipal or governmental agency having jurisdiction over SPS or its assets, which violation might have consequences that would materially and adversely affect the condition (financial or otherwise) or the operation of SPS or its assets or could reasonably be expected to have consequences that would materially and adversely affect the performance of its obligations and duties hereunder;

(v)         SPS is an approved Servicer for Xxxxxxx Mac in good standing. No event has occurred, including but not limited to a change in insurance coverage, which would make SPS unable to comply with Xxxxxxx Mac requirements or which would require notification to Xxxxxxx Mac for which notice has not been provided;

- 139 -

(vi)        There are no actions or proceedings against, or investigations of, SPS before any court, administrative or other tribunal (A) that could reasonably be expected to prohibit its entering into this Agreement, (B) seeking to prevent the consummation of the transactions contemplated by this Agreement or (C) that could reasonably be expected to prohibit or materially and adversely affect the performance by SPS of its obligations under, or the validity or enforceability of, this Agreement; and

(vii)       No consent, approval, authorization or order of any court or governmental agency or body is required for the execution, delivery and performance by SPS of, or compliance by SPS with, this Agreement or the consummation of the transactions contemplated by this Agreement, except for such consents, approvals, authorizations or orders, if any, that have been obtained prior to the date of this Agreement.

Section 10.29         Remedies for Breach of Representations and Warranties.

It is understood and agreed that the representations and warranties set forth in Section 10.28 shall survive (i) the engagement of SPS to perform the servicing responsibilities as of the date of this Agreement and (ii) any resignation or removal of SPS hereunder and shall inure to the benefit of the Trustee, for the benefit of the Certificateholders, and to the Master Servicer, the Depositor and the Securities Administrator. Upon discovery by any of the Trustee, the Master Servicer, the Depositor or the Securities Administrator of a breach of any of the foregoing representations and warranties that materially and adversely affects the ability of SPS to perform its duties and obligations under this Agreement or otherwise materially and adversely affects the value of the Mortgage Loans, the Mortgaged Properties or the interests of the Trustee, the Master Servicer, the Depositor or the Securities Administrator, the party discovering such breach shall give prompt written notice to the others.

Within 60 days of the earlier of either discovery by SPS, or notice to SPS, of any breach of a representation or warranty which materially and adversely affects the ability of SPS to perform its duties and obligations under this Agreement or otherwise materially and adversely affects the value of the Mortgage Loans or the Mortgaged Properties (in each case as determined by SPS), SPS shall use its best efforts promptly to cure such breach in all material respects.

Section 10.30         Indemnification by SPS.

SPS shall indemnify the Custodian, the Depositor, the Trustee, the Master Servicer and the Securities Administrator and in each case any officer, director, employee or agent of such party or any successor in interest to such party under this Agreement (for purposes of this paragraph, collectively, the “Indemnitees” and individually, an “Indemnitee”) and hold harmless any such Indemnitee against any and all losses, claims, damages, liabilities or expenses (including attorneys’ fees) (“Losses”) that any Indemnitee may sustain in any way related to (a) the failure of SPS to perform its obligations under this Agreement, including but not limited to its obligation to service and administer the Mortgage Loans in compliance with the terms of this Agreement or (b) a breach of SPS’s representations or warranties contained in Section 10.28; provided, however, that SPS shall not indemnify any Indemnitee to the extent that any such Losses resulted from the negligence, bad faith or willful misconduct of any such Indemnitee. The provisions of this Section 10.30 shall survive the resignation or termination of SPS or the termination of this Agreement.

- 140 -

Section 10.31         Merger or Consolidation of SPS.

SPS shall keep in full force and effect its existence and rights as a corporation and shall obtain and preserve its qualification to do business in any state in which such qualification is or shall be necessary to protect the validity and enforceability of this Agreement or any of the Mortgage Loans, and to enable SPS to perform its duties under this Agreement.

Any Person into which SPS may be merged or consolidated, or any corporation resulting from any merger, conversion or consolidation to which SPS shall be a party, or a sale of substantially all of the assets of SPS or any Person succeeding to the business of SPS, shall be the successor of SPS hereunder, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding; provided, however, that the successor or surviving Person shall (i) be an institution whose business is the servicing of mortgage loans, (ii) be a Xxxxxx Xxx or Xxxxxxx Mac approved servicer and (iii) have a net worth of at least $15,000,000.

Section 10.32         Limitation on Liability of SPS and Others.

Neither SPS nor any director, officer, employee or agent of SPS, will be under any liability to the Depositor, the Trustee, the Master Servicer or the Securities Administrator or the Certificateholders, for the taking of any action or for refraining from the taking of any action in good faith pursuant to this Agreement, or for errors in judgment; provided, however, that this provision shall not protect SPS or any such person against any breach of warranties or representations made herein, or failure to perform its obligations in compliance with any standard of care set forth in this Agreement, or any liability which would otherwise be imposed by reason of willful misfeasance, bad faith or negligence in the performance of his or its duties or by reason of reckless disregard of his or its obligations and duties hereunder. SPS, and any director, officer, employee or agent of SPS shall be entitled to indemnification from the assets of the Trust Fund and will be held harmless against any loss, liability or expense (including attorneys’ fees) incurred in connection with the performance of its duties and obligations, including following any direction, approval or consent or deemed direction, approval or consent, received by SPS pursuant to Section 2.08, and any legal action relating to this Agreement or the Certificates, but excluding any loss, liability or expense incurred by reason of willful misfeasance, bad faith or negligence in the performance of its duties hereunder or by reason of reckless disregard of its obligations and duties hereunder. SPS and any officer, employee or agent of SPS may rely in good faith on any document or direction of any kind prima facie properly executed and submitted by any Person respecting any matters arising hereunder. SPS shall not be under any obligation to appear in, prosecute or defend any legal action which is not incidental to its duty to service the Mortgage Loans in accordance with this Agreement and which in its opinion may result in its incurring any expenses or liability; provided, however, that SPS may undertake any such action which it may deem necessary or desirable in respect to this Agreement and the rights and duties of the parties hereto. In such event, the legal expenses and costs of such action and any liability resulting therefrom shall be expenses, costs and liabilities for which the Issuer shall be liable, SPS shall be entitled to reimbursement therefor from the Trust Fund pursuant to Section 10.06 except when such expenses, costs and liabilities are subject to SPS’s indemnification under Section 10.30.

- 141 -

Section 10.33         Servicer Not to Resign.

SPS shall not assign this Agreement or resign from the obligations and duties hereby imposed on it except by mutual written consent of SPS, the Depositor, the Seller, the Master Servicer, the Trustee and the Securities Administrator, which consents shall not be unreasonably withheld, or upon the determination that its servicing duties hereunder are no longer permissible under applicable law and such incapacity cannot be cured by SPS in which event SPS may resign as servicer. Any such determination that its servicing duties hereunder are no longer permissible under applicable law permitting the resignation of SPS as servicer shall be evidenced by an Officer’s Certificate to such effect delivered to the Depositor, the Seller, the Master Servicer, the Trustee and the Securities Administrator. Notwithstanding the foregoing, SPS has the right to assign this Agreement or resign as Servicer hereunder if (i) SPS has proposed a successor Servicer to the Master Servicer and each Rating Agency in writing and such proposed successor Servicer is reasonably acceptable to the Seller, the Trustee and the Depositor, (ii) each Rating Agency has confirmed that such assignment or resignation will not cause the withdrawal or downgrade of any rating on the Certificates (if Outstanding and rated by such Rating Agency) and (iii) such successor Servicer meets the eligibility requirements of Section 9.01 of this Agreement to act as Servicer hereunder and agrees to service in accordance with this Agreement. Any reasonable costs and expenses of the Trustee, the Seller and the Master Servicer incurred in connection with such assignment or resignation and transfer of servicing shall be paid by SPS or if SPS fails to pay such costs and expenses within sixty (60) days of written request therefor, the Trust Fund shall pay such costs and expenses. No assignment or resignation of SPS as set forth in this Section 10.33 shall become effective until a successor shall have assumed SPS’s responsibilities and obligations hereunder in the manner provided in Section 9.01.

Notwithstanding the foregoing, at the request of Five Oaks, upon at least ninety (90) days prior written notice, and with respect to all or a portion of the Mortgage Loans, SPS shall resign, such resignation to be come effective only upon the selection and appointment of a successor servicer (who shall meet the requirements of Section 9.01 hereof) by Five Oaks and the assumption by such successor servicer of the servicing responsibilities of SPS hereunder. On the related servicing transfer date, the successor servicer shall pay SPS all unpaid and accrued Servicing Fees, reimburse SPS for any unreimbursed Advances and Servicing Advances and reimburse SPS for its servicing transfer costs.

Section 10.34         Termination for Cause.

In case one or more of the following events of default by SPS (each, an “SPS Event of Default”) shall occur and be continuing, that is to say:

(i)          any failure by SPS to remit to the Securities Administrator any payment required to be made under the terms of this Agreement (other than an Advance) which continues unremedied for a period of one (1) Business Day after the date upon which written notice of such failure, requiring the same to be remedied, shall have been received by SPS from the Securities Administrator; or

(ii)         any failure on the part of SPS duly to observe or perform in any material respect any other of the covenants or agreements on the part of SPS set forth in this Agreement which continues unremedied for a period of thirty (30) days after the date on which written notice of such failure, requiring the same to be remedied, shall have been received by SPS from the Master Servicer; or

(iii)        a decree or order of a court or agency or supervisory authority having jurisdiction for the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshalling of assets and liabilities or similar proceedings, or for the winding-up or liquidation of its affairs, shall have been entered against SPS and such decree or order shall have remained in force undischarged or unstayed for a period of sixty (60) days; or

- 142 -

(iv)        SPS shall consent to the appointment of a conservator or receiver or liquidator in any insolvency, bankruptcy, readjustment of debt, marshalling of assets and liabilities or similar proceedings of or relating to SPS or of or relating to all or substantially all of its property; or

(v)         SPS shall admit in writing its inability to pay its debts generally as they become due, file a petition to take advantage of any applicable insolvency or reorganization statute, make an assignment for the benefit of its creditors, or voluntarily suspend payment of its obligations; or

(vi)        Any failure of SPS Servicer to make any Advances when such Advances are due, which failure continues unremedied for a period of one (1) Business Day;

then, so long as a SPS Event of Default described in clauses (i) through (v) of this Section shall occur and shall not have been remedied within the applicable grace period, if any, or waived pursuant to Section 6.16 hereof, the Master Servicer or Five Oaks, by notice in writing to SPS may, and, if so directed in writing by Certificateholders evidencing either (i) more than 50% of the Class Principal Amount (or Class Notional Amount) of each Class of Certificates, or (ii) 50% of the aggregate Class Principal Amount of the Subordinate Certificates, or upon the occurrence of an SPS Event of Default described in clause (vi) of this Section, shall, by notice then given in writing to SPS, terminate all of the rights and obligations of SPS as servicer under this Agreement.

Immediately upon receipt by SPS of such written notice, all authority and power of SPS to service the Mortgage Loans under this Agreement shall be terminated, and such authority and power shall pass to and be vested in the Master Servicer or in a successor Servicer pursuant to Section 9.01 appointed by the Master Servicer (with the consent of Five Oaks, such consent not to be unreasonably withheld) or by Five Oaks, as the case may be, provided, that in the event Five Oaks does not respond within seven (7) Business Days to any such request for consent by the Master Servicer, such requirement of consent shall be deemed to be waived; provided, however, SPS shall discharge its duties and responsibilities under this Agreement during the period from the date it receives such written notice of termination until the date servicing is transferred to a successor Servicer with the same degree of diligence and prudence that it is obligated to exercise under this Agreement, and shall take no action whatsoever that could reasonably be expected to impair or prejudice the rights or financial condition of the Depositor, the Master Servicer, the Securities Administrator, the Trustee, the Certificateholders or the successor Servicer. Upon written request from the Master Servicer or Five Oaks, SPS shall prepare, execute and deliver to the Master Servicer or other successor Servicer, any and all documents and other instruments, place in such successor’s possession all Servicing Files, and do or cause to be done all other acts or things necessary or appropriate to effect the purposes of such notice of termination, at SPS’s sole expense. SPS shall cooperate with the Trustee, the Master Servicer, Five Oaks and such successor Servicer in effecting the transfer of SPS’s responsibilities and rights hereunder, including without limitation, the transfer to such successor for administration by it of all cash amounts which shall at the time be credited by SPS to the Collection Account and Escrow Account with respect to the Trust Fund or thereafter received with respect to the Mortgage Loans. SPS shall, after its termination, retain the right to be paid Servicing Fees and be reimbursed for any unreimbursed Advances and/or Servicing Advances earned or made until the date of transfer of servicing to a successor Servicer; provided, however that (i) such fees and advances shall be paid or reimbursed solely from those sources of funds described in this Agreement as being eligible funds for the payment or reimbursement of such amounts, (ii) such fees and advances shall be paid or reimbursed solely in accordance with the terms of this Agreement and (iii) the successor Servicer shall cause such amounts to be paid or reimbursed to SPS on a first-in, first-out basis consistent with this Agreement.

- 143 -

Section 10.35       Advances.

With respect to the Mortgage Loans, SPS shall deposit in the Collection Account as Advances, an amount equal to all Scheduled Payments (with interest at the Mortgage Rate less the related Servicing Fee Rate) which were due on such Mortgage Loans serviced by it during the applicable Collection Period and which were delinquent at the close of business on the immediately preceding Determination Date. SPS’s obligation to make such Advances will continue through the last Scheduled Payment due prior to the payment in full of such Mortgage Loan, or through the date that the related Mortgaged Property has, in the judgment of SPS, been completely liquidated. SPS shall not be required to advance shortfalls of principal or interest resulting from the application of the Civil Relief Act.

To the extent required by Accepted Servicing Practices, SPS shall be obligated to make Advances in accordance with the provisions of this Agreement; provided, however, that such obligation shall cease if SPS determines, in its reasonable opinion, that Advances with respect to a Mortgage Loan are Nonrecoverable Advances. In the event that SPS determines that any such Advances are Nonrecoverable Advances, SPS shall provide the Master Servicer with an Officer’s Certificate signed by a Servicing Officer evidencing such determination. Upon the Master Servicer’s receipt of such certificate, the Master Servicer shall send a copy of such certificate to the Securities Administrator and the Trustee.

If an Advance is required to be made hereunder by SPS, SPS shall on the Servicer Remittance Date either (i) deposit in the Collection Account from its own funds an amount equal to such Advance, (ii) cause to be made an appropriate entry in the records of the Collection Account that funds in such account being held for future distribution or withdrawal have been used by SPS to make such Advance or (iii) make Advances in the form of any combination of clauses (i) and (ii) aggregating the amount of such Advance. Any such funds being held in the Collection Account for future distribution and so used shall be replaced by SPS from its own funds by deposit in the Collection Account, or from other funds in the Collection Account being held for future distributions, on or before any future Distribution Date in which such funds would be due.

Article XI

REMIC AND GRANTOR ADMINISTRATION

Section 11.01       REMIC Administration.

(a)          REMIC elections as set forth in the Preliminary Statement to this Agreement shall be made by the Trustee at the direction of the Securities Administrator on Forms 1066 or other appropriate federal tax or information return for the taxable year ending on the last day of the calendar year in which the Certificates are issued. The regular interests and residual interest in each REMIC shall be as designated in the Preliminary Statement to this Agreement.

(b)          The Closing Date is hereby designated as the “Startup Day” of each REMIC within the meaning of section 86OG(a)(9) of the Code. The “latest possible maturity date” for each REMIC for purposes of Treasury Regulation 1.86OG-1(a)(4) will be the Latest Possible Maturity Date.

- 144 -

(c)          The Securities Administrator shall represent the Trust Fund in any administrative or judicial proceeding relating to an examination or audit by any governmental taxing authority with respect thereto. The Securities Administrator shall pay any and all tax-related expenses (not including taxes) of each REMIC, including but not limited to any professional fees or expenses related to audits or any administrative or judicial proceedings with respect to such REMIC that involve the Internal Revenue Service or state tax authorities, but only to the extent that (i) such expenses are ordinary or routine expenses, including expenses of a routine audit but not expenses of litigation (except as described in (ii)); or (ii) such expenses or liabilities (including taxes and penalties) are attributable to the negligence or willful misconduct of the Securities Administrator in fulfilling its duties hereunder (including its duties as tax return preparer). The Securities Administrator shall be entitled to reimbursement of expenses to the extent provided in clause (i) above from the Distribution Account; provided, however, the Securities Administrator shall not be entitled to reimbursement for expenses incurred in connection with the preparation of tax returns and other reports required under Section 6.20 and this Section.

(d)          The Securities Administrator shall prepare and file, and the Trustee shall sign, all of each REMIC’s federal and appropriate state tax and information returns as such REMIC’s direct representative. The expenses of preparing and filing such returns shall be borne by the Securities Administrator. In preparing such returns, the Securities Administrator shall, with respect to each REMIC created hereunder other than REMIC 3 (each such REMIC, a “Lower-Tier REMIC”): (i) treat the accrual period for interests in such Lower-Tier REMIC as the calendar month; (ii) account for distributions made from such Lower-Tier REMIC as made on the first day of each succeeding calendar month; (iii) use the aggregation method provided in Treasury Regulation section 1.1275-2(c); and (iv) account for income and expenses related to such Lower-Tier REMIC in the manner resulting in the lowest amount of excess inclusion income possible accruing to the Holder of the residual interest in such Lower-Tier REMIC.

(e)          The Securities Administrator or its designee shall perform on behalf of each REMIC all reporting and other tax compliance duties that are the responsibility of such REMIC under the Code, the REMIC Provisions, or other compliance guidance issued by the Internal Revenue Service or any state or local taxing authority. Among its other duties, if required by the Code, the REMIC Provisions, or other such guidance, the Securities Administrator shall provide (i) to the Treasury or other governmental authority such information as is necessary for the application of any tax relating to the transfer of a Residual Certificate to any disqualified person or organization pursuant to Treasury Regulation 1.860E-2(a)(5) and any person designated in Section 860E(e)(3) of the Code and (ii) to the Trustee such information as is necessary for the Trustee to provide to the Certificateholders such information or reports as are required by the Code or REMIC Provisions.

(f)          The Trustee, the Securities Administrator, the Master Servicer and the Holders of Certificates shall, to the extent within their knowledge and control, take such actions as may be necessary to maintain the status of each REMIC as a REMIC under the REMIC Provisions and shall assist each other as necessary to maintain such status. None of the Trustee, the Securities Administrator, the Master Servicer or the Holder of any Residual Certificate shall knowingly take any action, cause any REMIC to take any action or fail to take (or fail to cause to be taken) any action that, under the REMIC Provisions, if taken or not taken, as the case may be, could result in an Adverse REMIC Event unless the Trustee, the Securities Administrator and the Master Servicer have received an Opinion of Counsel (at the expense of the party seeking to take such action or not to take such action) to the effect that the contemplated action (or inaction, as the case may be) will not cause an Adverse REMIC Event. In addition, prior to taking any action with respect to any REMIC or the assets therein, or causing any REMIC to take any action, which is not expressly permitted under the terms of this Agreement, any Holder of a Residual Certificate will consult with the Trustee, the Securities Administrator, the Master Servicer or their respective designees, in writing, with respect to whether such action could cause an Adverse REMIC Event to occur with respect to any REMIC, and no such Person shall take any such action or cause any REMIC to take any such action as to which the Trustee, the Securities Administrator or the Master Servicer has advised it in writing that an Adverse REMIC Event could occur; provided, however, that if no Adverse REMIC Event would occur but such action could result in the imposition of additional taxes on the Residual Certificateholders, no such Person shall take any such action, or cause any REMIC to take any such action without the written consent of the other Residual Certificateholders. The Trustee, the Securities Administrator and the Master Servicer may consult with counsel (and conclusively rely upon the advice of such counsel) to make such written advice, and the cost of the same shall be borne by the party seeking to take the action not expressly permitted by this Agreement, but in no event shall such cost be an expense of the Trustee, Securities Administrator or the Master Servicer.

- 145 -

(g)          Each Holder of a Residual Certificate shall pay when due any and all taxes imposed on the related REMIC by federal or state governmental authorities. To the extent that such taxes are not paid by a Residual Certificateholder, the Securities Administrator or the Paying Agent shall pay any remaining REMIC taxes out of current or future amounts otherwise distributable to the Holder of the Residual Certificate in any such REMIC or, if no such amounts are available, out of other amounts held in the Distribution Account, and shall reduce amounts otherwise payable to holders of regular interests in any such REMIC, as the case may be.

(h)          The Securities Administrator shall, for federal income tax purposes, maintain books and records with respect to each REMIC on a calendar year and on an accrual basis.

(i)          No additional contributions of assets shall be made to any REMIC, except as expressly provided in this Agreement.

(j)          None of the Trustee, the Securities Administrator nor the Master Servicer shall enter into any arrangement by which any REMIC will receive a fee or other compensation for services.

(k)          The Holder (or, if there is more than one such Holder, the Holder with the largest Percentage Interest) of the Class R Certificate is hereby designated as Tax Matters Person with respect to each REMIC and such Holder shall be deemed by the acceptance of its Certificate to have appointed the Securities Administrator to act as its agent to perform the duties of the Tax Matters Person for each such REMIC.

Section 11.02         Prohibited Transactions and Activities.

None of the Depositor, the Master Servicer or the Trustee shall sell, dispose of, or substitute for any of the Mortgage Loans, except in a disposition pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the Trust Fund, (iii) the termination of each REMIC pursuant to Article VII of this Agreement or (iv) a repurchase or substitution of Mortgage Loans pursuant to Article II of this Agreement, nor acquire any assets for any REMIC, nor sell or dispose of any investments in the Distribution Account for gain, nor accept any contributions to any REMIC after the Closing Date, nor permit modifications other than Servicing Modifications, unless it has received an Opinion of Counsel (at the expense of the party causing such sale, disposition, or substitution) that such disposition, acquisition, substitution, or acceptance will not (a) result in an Adverse REMIC Event, (b) adversely affect the distribution of interest or principal on the Certificates or (c) result in the encumbrance of the assets transferred or assigned to the Trust Fund (except pursuant to the provisions of this Agreement).

- 146 -

Section 11.03       Indemnification With Respect to Prohibited Transactions or Loss of REMIC Status.

Upon the occurrence of an Adverse REMIC Event due to the negligent performance by either the Securities Administrator or the Master Servicer of its duties and obligations set forth herein, the Securities Administrator or the Master Servicer, as applicable, shall indemnify the Certificateholders of the related Residual Certificate against any and all losses, claims, damages, liabilities or expenses (“Losses”) resulting from such negligence; provided, however, that neither the Securities Administrator nor the Master Servicer shall be liable for any such Losses attributable to the action or inaction of the Depositor, the Trustee or the Holder of the Residual Certificate, nor for any such Losses resulting from misinformation provided by any of the foregoing parties on which the Securities Administrator or the Master Servicer, as applicable, has relied. Notwithstanding the foregoing, however, in no event shall the Securities Administrator or the Master Servicer have any liability (1) for any action or omission that is taken in accordance with and in compliance with the express terms of, or which is expressly permitted by the terms of, this Agreement or under any Servicing Agreement, (2) for any Losses other than arising out of malfeasance, willful misconduct or negligent performance by the Securities Administrator or the Master Servicer, as applicable, of its duties and obligations set forth herein, and (3) for any special or consequential damages to Certificateholders of the related Residual Certificate (in addition to payment of principal and interest on the Certificates).

Section 11.04       REO Property.

(a)          Notwithstanding any other provision of this Agreement, the Master Servicer, acting on behalf of the Trustee hereunder, shall not, except to the extent provided in the applicable Servicing Agreement, knowingly permit any Servicer to rent, lease, or otherwise earn income on behalf of any REMIC with respect to any REO Property which might cause an Adverse REMIC Event unless the applicable Servicer has provided to the Trustee and the Securities Administrator an Opinion of Counsel concluding that, under the REMIC Provisions, such action would not result in an Adverse REMIC Event.

(b)          The Depositor shall cause the applicable Servicer (to the extent provided in the related Servicing Agreement) to make reasonable efforts to sell any REO Property for its fair market value. In any event, however, the Depositor shall, or shall cause the applicable Servicer (to the extent provided in the related Servicing Agreement) to, dispose of any REO Property within three years of its acquisition by the Trust Fund unless the Depositor or the applicable Servicer (on behalf of the Trust Fund) has received an extension from the Internal Revenue Service to the effect that, under the REMIC Provisions and any relevant proposed legislation and under applicable state law, the REMIC may hold REO Property for a longer period without causing an Adverse REMIC Event. If such an extension has been received, then the Depositor, acting on behalf of the Trustee hereunder, shall, or shall cause the applicable Servicer to, continue to attempt to sell the REO Property for its fair market value for such period longer than three years as such extension permits (the “Extended Period”). If such an extension has not been received and the Depositor or the applicable Servicer, acting on behalf of the Trust Fund hereunder, is unable to sell the REO Property within 33 months after its acquisition by the Trust Fund, or if such an extension has been received and the Depositor or the applicable Servicer is unable to sell the REO Property within the period ending three months before the close of the Extended Period, the Depositor shall cause the applicable Servicer, before the end of the three year period or the Extended Period, as applicable, to (i) purchase (except in the case of Shellpoint Mortgage Servicing) such REO Property at a price equal to the REO Property’s fair market value or (ii) auction the REO Property to the highest bidder (which may be the applicable Servicer) in an auction reasonably designed to produce a fair price prior to the expiration of the three-year period or the Extended Period, as the case may be.

- 147 -

Section 11.05       Grantor Trust Administration.

(a)          There is hereby established a separate trust (the “Grantor Trust”), which shall be a grantor trust for federal income tax purposes. The Grantor Trust shall be maintained by the Trustee in its name, for the benefit of the Holders of the Grantor Trust Certificates. The assets of the Grantor Trust shall consist of the Grantor Trust Assets, which have been placed in the Grantor Trust. The Grantor Trust Assets in the Grantor Trust shall be held by the Trustee. The Initial Exchangeable Certificates and the Exchangeable Certificates represent undivided beneficial ownership of REMIC Regular Interest Combinations depending on which Class of Initial Exchangeable Certificates or Exchangeable Certificates is outstanding.

(b)          The Securities Administrator shall treat the Grantor Trust for tax return preparation purposes as a grantor trust under the Code and, if necessary, under applicable state law and will file appropriate federal or state tax returns for each taxable year ending on or after the last day of the calendar year in which the Certificates are issued. The Non-Exchangeable Certificates, and the Initial Exchangeable Certificates and the Exchangeable Certificates that are outstanding are hereby designated as representing beneficial ownership interests in the Grantor Trust.

(c)          The Securities Administrator shall pay out of its own funds any and all routine tax administration expenses of the Issuer incurred with respect to the Grantor Trust (but not including any professional fees or expenses related to audits or any administrative or judicial proceedings with respect to the Issuer that involve the IRS or state tax authorities which extraordinary expenses shall be payable or reimbursable to the Securities Administrator from the Grantor Trust Assets) unless otherwise provided in Section 11.05(k).

(d)          The Securities Administrator shall prepare and upon execution by the Trustee, shall file all of the tax returns in respect of the Grantor Trust. The Trustee shall execute all of the tax returns in respect of the Grantor Trust. The expenses of preparing and filing such returns shall be borne by the Securities Administrator without any right of reimbursement therefor.

(e)          The Grantor Trust is a WHFIT that is a WHMT. The Securities Administrator shall report as required under the WHFIT Regulations to the extent such information as is reasonably necessary to enable the Securities Administrator to do so is provided to the Securities Administrator on a timely basis. The “middlemen” as defined by the WHFIT Regulations shall be Cede & Co., the nominee of DTC. The Securities Administrator shall not be liable for any tax reporting penalties that may arise under the WHFIT Regulations as a result of the Issuer incorrectly determining the status of the Grantor Trust as a WHFIT or failing to identify whether or not the Grantor Trust is a WHFIT.

(f)          The Securities Administrator, in its discretion, shall report required WHFIT information using either the cash or accrual method, except to the extent the WHFIT Regulations specifically require a different method. The Securities Administrator shall be under no obligation to determine whether any Certificateholder uses the cash or accrual method. The Securities Administrator shall make available WHFIT information to Certificateholders annually. In addition, the Securities Administrator shall not be responsible or liable for providing subsequently amended, revised or updated information to any Certificateholder, unless requested by the Certificateholder.

(g)          The Securities Administrator shall not be liable for failure to meet the reporting requirements of the WHFIT Regulations or for any penalties thereunder if such failure is due to: (i) the lack of reasonably necessary information being provided to the Securities Administrator or (ii) incomplete, inaccurate or untimely information being provided to the Securities Administrator. Each owner of a Class of Certificates representing, in whole or in part, beneficial ownership of an interest in a WHFIT, by acceptance of its interest in such Class of Certificates, shall be deemed to have agreed to provide the Securities Administrator with information regarding any sale of such Certificates, including the price, amount of proceeds and date of sale. Absent receipt of such information, and unless informed otherwise by the Depositor, the Securities Administrator will assume there is no secondary market trading of WHFIT interests.

- 148 -

(h)          To the extent required by the WHFIT Regulations, the Securities Administrator shall use reasonable efforts to publish on an appropriate website the CUSIPs for the Certificates that represent ownership of an interest in a WHFIT.

(i)          The Securities Administrator shall perform on behalf of the Grantor Trust all reporting and other tax compliance duties that are required in respect thereof under the Code, the Grantor Trust Provisions or other compliance guidance issued by the IRS or any state or local taxing authority.

(j)          The Securities Administrator shall perform its duties hereunder so as to maintain the status of the Grantor Trust as a grantor trust under the Grantor Trust Provisions. The Securities Administrator shall not knowingly take (or cause any Grantor Trust to take) any action or fail to take (or fail to cause to be taken) any action that, under the Grantor Trust Provisions, if taken or not taken, as the case may be, could result in an Adverse Grantor Trust Event, unless the Securities Administrator has obtained or received an Opinion of Counsel (at the expense of the party requesting such action or at the expense of the Grantor Trust if the Securities Administrator seeks to take such action or to refrain from taking any action for the benefit of the Grantor Trust Certificateholders) to the effect that the contemplated action will not result in an Adverse Grantor Trust Event. None of the other parties hereto shall take any action or fail to take any action (whether or not authorized hereunder) as to which the Securities Administrator has advised it in writing that the Securities Administrator has received or obtained an Opinion of Counsel to the effect that an Adverse Grantor Trust Event could result from such action or failure to act. The Securities Administrator may consult with counsel to make such written advice at the expense of the party requesting such action or at the expense of the Grantor Trust if the Securities Administrator seeks to take such action or to refrain from taking any action for the benefit of the Grantor Trust Certificateholders.

(k)          If any tax is imposed on any Grantor Trust, such tax, together with all incidental costs and expenses (including penalties and reasonable attorneys’ fees), shall be charged to and paid by: (i) the Securities Administrator to the extent such amounts are attributable to the negligence or willful misconduct of the Securities Administrator in fulfilling its duties hereunder (including its duties as tax return preparer) or (ii) the Grantor Trust Assets in all other instances.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

On each Distribution Date, the Paying Agent, on behalf of the Trustee, will make distributions from the Distribution Account to the Holders of Certificates according to the terms of the Pooling and Servicing Agreement. All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated among the outstanding Certificates of such Class based on the Certificate Principal Amount (or Notional Amount) or Percentage Interest of each such Certificate.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

The Corporate Trust Office with respect to the presentment and surrender of Certificates for the final distribution thereon is the corporate trust office of the Certificate Registrar at Xxxxx Xxxxxx xxx Xxxxxxxxx Xxxxxx, Xxxxxxxxxxx, Xxxxxxxxx 00000, Attention: Corporate Trust Services — CSMC Trust 2014-OAK1 or at such other address as the Securities Administrator may designate from time to time.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class of authorized denominations evidencing the same initial Certificate Principal Amount (or Notional Amount) or Percentage Interest will be issued to the designated transferee or transferees. As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for new Certificates of the same Class evidencing the same aggregate initial Certificate Principal Amount (or Notional Amount) as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.

The Certificates are issued in the denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

The Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.

All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated among the outstanding Certificates of such Class based on the Certificate Principal Amount (or Notional Amount) or Percentage Interest of each such Certificate.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

The Corporate Trust Office with respect to the presentment and surrender of Certificates for the final distribution thereon is the corporate trust office of the Certificate Registrar at Xxxxx Xxxxxx xxx Xxxxxxxxx Xxxxxx, Xxxxxxxxxxx, Xxxxxxxxx 00000, Attention: Corporate Trust Services — CSMC Trust 2014-OAK1 or at such other address as the Securities Administrator may designate from time to time.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

The Certificates are issued in the denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

On each Distribution Date, the Paying Agent, on behalf of the Trustee, will make distributions from the Distribution Account to the Holders of Certificates according to the terms of the Pooling and Servicing Agreement. All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated among the outstanding Certificates of such Class based on the Certificate Principal Amount (or Notional Amount) or Percentage Interest of each such Certificate.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

The Corporate Trust Office with respect to the presentment and surrender of Certificates for the final distribution thereon is the corporate trust office of the Certificate Registrar at Xxxxx Xxxxxx xxx Xxxxxxxxx Xxxxxx, Xxxxxxxxxxx, Xxxxxxxxx 00000, Attention: Corporate Trust Services — CSMC Trust 2014-OAK1 or at such other address as the Securities Administrator may designate from time to time.

The Pooling and Servicing Agreement may be amended by the Trustee, the Master Servicer, the Securities Administrator, SPS and the Depositor with the consent of the Holders of not less than 66-2/3% of the Class Principal Amount or Class Notional Amount (or Percentage Interest) of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders; provided, however, that no such amendment shall be made unless the Trustee and the Securities Administrator receive an Opinion of Counsel, at the expense of the party requesting the change, that such change will not cause an Adverse REMIC Event; and provided further, that no such amendment may (i) reduce in any manner the amount of, or delay the timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate, without the consent of the Holder of such Certificate or (ii) reduce the aforesaid percentages of Class Principal Amount or Class Notional Amount (or Percentage Interest) of Certificates of each Class, the Holders of which are required to consent to any such amendment without the consent of the Holders of 100% of the Class Principal Amount or Class Notional Amount (or Percentage Interest) of each Class of Certificates affected thereby.  For purposes of this paragraph, references to “Holder” or “Holders” shall be deemed to include, in the case of any Class of Book-Entry Certificates, the related Certificate Owners. Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class of authorized denominations evidencing the same initial Certificate Principal Amount (or Notional Amount) or Percentage Interest will be issued to the designated transferee or transferees. As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for new Certificates of the same Class evidencing the same aggregate initial Certificate Principal Amount (or Notional Amount) as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.

The Certificates are issued in the denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

The Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.

Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

Except as otherwise defined herein, all capitalized terms used herein shall have the meanings ascribed to them in the Pooling and Servicing Agreement.

On each Distribution Date, the Paying Agent, on behalf of the Trustee, will make distributions from the Distribution Account to the Holders of Certificates according to the terms of the Pooling and Servicing Agreement. All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated among the outstanding Certificates of such Class based on the Certificate Principal Amount (or Notional Amount) or Percentage Interest of each such Certificate.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

The Corporate Trust Office with respect to the presentment and surrender of Certificates for the final distribution thereon is the corporate trust office of the Certificate Registrar at Xxxxx Xxxxxx xxx Xxxxxxxxx Xxxxxx, Xxxxxxxxxxx, Xxxxxxxxx 00000, Attention: Corporate Trust Services — CSMC Trust 2014-OAK1 or at such other address as the Securities Administrator may designate from time to time.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class of authorized denominations evidencing the same initial Certificate Principal Amount (or Notional Amount) or Percentage Interest will be issued to the designated transferee or transferees. As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for new Certificates of the same Class evidencing the same aggregate initial Certificate Principal Amount (or Notional Amount) as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.

The Certificates are issued in the denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

The Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.

Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class of authorized denominations evidencing the same initial Certificate Principal Amount (or Notional Amount) or Percentage Interest will be issued to the designated transferee or transferees.

No service charge will be made for any such registration of transfer or exchange, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.

The Certificates are issued in the denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

The Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.

Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

On each Distribution Date, the Paying Agent, on behalf of the Trustee, will make distributions from the Distribution Account to the Holders of Certificates according to the terms of the Pooling and Servicing Agreement. All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated among the outstanding Certificates of such Class based on the Certificate Principal Amount (or Notional Amount) or Percentage Interest of each such Certificate.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

The Corporate Trust Office with respect to the presentment and surrender of Certificates for the final distribution thereon is the corporate trust office of the Certificate Registrar at Xxxxx Xxxxxx xxx Xxxxxxxxx Xxxxxx, Xxxxxxxxxxx, Xxxxxxxxx 00000, Attention: Corporate Trust Services — CSMC Trust 2014-OAK1 or at such other address as the Securities Administrator may designate from time to time.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class of authorized denominations evidencing the same initial Certificate Principal Amount (or Notional Amount) or Percentage Interest will be issued to the designated transferee or transferees. As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for new Certificates of the same Class evidencing the same aggregate initial Certificate Principal Amount (or Notional Amount) as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.

The Certificates are issued in denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

The Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.

As provided in the Pooling and Servicing Agreement, this Certificate and the Pooling and Servicing Agreement shall be construed in accordance with and governed by the laws of the State of New York without regard to the conflict of laws principles applied in the State of New York. In the event of any conflict between the provisions of this Certificate and the Pooling and Servicing Agreement, the Pooling and Servicing Agreement shall be controlling.

On each Distribution Date, the Paying Agent, on behalf of the Trustee, will make distributions from the Distribution Account to the Holders of Certificates according to the terms of the Pooling and Servicing Agreement. All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated among the outstanding Certificates of such Class based on the Certificate Principal Amount (or Notional Amount) or Percentage Interest of each such Certificate.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

The Corporate Trust Office with respect to the presentment and surrender of Certificates for the final distribution thereon is the corporate trust office of the Certificate Registrar at Xxxxx Xxxxxx xxx Xxxxxxxxx Xxxxxx, Xxxxxxxxxxx, Xxxxxxxxx 00000, Attention: Corporate Trust Services -- CSMC Trust 2014-OAK1 or at such other address as the Securities Administrator may designate from time to time.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class of authorized denominations evidencing the same initial Certificate Principal Amount (or Notional Amount) or Percentage Interest will be issued to the designated transferee or transferees. As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for new Certificates of the same Class evidencing the same aggregate initial Certificate Principal Amount (or Notional Amount) as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.

The Certificates are issued in denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

The Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.

Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

Except as otherwise defined herein, all capitalized terms used herein shall have the meanings ascribed to them in the Pooling and Servicing Agreement.

On each Distribution Date, the Paying Agent, on behalf of the Trustee, will make distributions from the Distribution Account to the Holders of Certificates according to the terms of the Pooling and Servicing Agreement. All distributions or allocations made with respect to each Class of Certificates on each Distribution Date shall be allocated among the outstanding Certificates of such Class based on the Certificate Principal Amount (or Notional Amount) or Percentage Interest of each such Certificate.

Distributions on this Certificate will be made by check mailed to the Holder of record of this Certificate on the immediately preceding Record Date at the address of such Holder as its appears on the Certificate Register or, upon written request made to the Securities Administrator at least five Business Days prior to the related Record Date, by any Certificateholder owning an aggregate initial Certificate Principal Amount or Notional Amount of at least $1,000,000 or, in the case of any Residual Certificate, a Percentage Interest of 100%, by wire transfer in immediately available funds to an account specified in such request and at the expense of such Certificateholder requesting such wire transfer by deducting a wire transfer fee from the related distribution; provided, however, that the final distribution in respect of any Certificate shall be made only upon presentation and surrender of such Certificate at the Corporate Trust Office (as defined below); provided, further, that the foregoing provisions shall not apply to any Certificate as long as such Certificate remains a Book-Entry Certificate, in which case all payments made shall be made through the Clearing Agency and its Clearing Agency Participants. Notwithstanding such final payment of principal of any of the Certificates, each Residual Certificate will remain outstanding until the termination of the related REMIC or REMICs and the payment in full of all other amounts due with respect to the Residual Certificates and at such time such final payment in retirement of any Residual Certificate will be made only upon presentation and surrender of such Certificate at the Corporate Trust Office.

The Corporate Trust Office with respect to the presentment and surrender of Certificates for the final distribution thereon is the corporate trust office of the Certificate Registrar at Xxxxx Xxxxxx xxx Xxxxxxxxx Xxxxxx, Xxxxxxxxxxx, Xxxxxxxxx 00000, Attention: Corporate Trust Services — CSMC Trust 2014-OAK1 or at such other address as the Securities Administrator may designate from time to time.

The Pooling and Servicing Agreement may be amended by the Trustee, the Master Servicer, the Securities Administrator, SPS and the Depositor with the consent of the Holders of not less than 66-2/3% of the Class Principal Amount or Class Notional Amount (or Percentage Interest) of each Class of Certificates affected thereby for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Pooling and Servicing Agreement or of modifying in any manner the rights of the Holders; provided, however, that no such amendment shall be made unless the Trustee and the Securities Administrator receive an Opinion of Counsel, at the expense of the party requesting the change, that such change will not cause an Adverse REMIC Event; and provided further, that no such amendment may (i) reduce in any manner the amount of, or delay the timing of, payments received on Mortgage Loans which are required to be distributed on any Certificate, without the consent of the Holder of such Certificate or (ii) reduce the aforesaid percentages of Class Principal Amount or Class Notional Amount (or Percentage Interest) of Certificates of each Class, the Holders of which are required to consent to any such amendment without the consent of the Holders of 100% of the Class Principal Amount or Class Notional Amount (or Percentage Interest) of each Class of Certificates affected thereby.  For purposes of this paragraph, references to “Holder” or “Holders” shall be deemed to include, in the case of any Class of Book-Entry Certificates, the related Certificate Owners. Any consent by the Holder of this Certificate will be conclusive and binding upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not consent is made with respect to such Certificate. The Pooling and Servicing Agreement also permits the amendment thereof in certain limited circumstances without the consent of the Holders.

As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registerable in the Certificate Register upon surrender of this Certificate for registration of transfer at the Corporate Trust Office, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Certificate Registrar duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class of authorized denominations evidencing the same initial Certificate Principal Amount (or Notional Amount) or Percentage Interest will be issued to the designated transferee or transferees. As provided in the Pooling and Servicing Agreement and subject to certain limitations therein set forth, this Certificate is exchangeable for new Certificates of the same Class evidencing the same aggregate initial Certificate Principal Amount (or Notional Amount) as requested by the Holder surrendering the same. No service charge will be made for any such registration of transfer or exchange, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.

The Certificates are issued in the denominations set forth in the Pooling and Servicing Agreement. The Certificates shall remain outstanding until the final Distribution Date for the Certificates.

On any date on which the Aggregate Stated Principal Balance has declined to less than 10% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates. If the Holder or Holders of the majority of the Class Principal Amount of the most subordinate Class of Certificates outstanding does not exercise such option, on any date on which the Aggregate Stated Principal Balance has declined to less than 3% of the Aggregate Stated Principal Balance as of the Cut-off Date, subject to satisfaction of the conditions described in the Pooling and Servicing Agreement, the Master Servicer may purchase all of the Mortgage Loans from the Trust Fund, thereby causing an early retirement of the Certificates.

In no event will the trust created by the Pooling and Servicing Agreement continue beyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Pooling and Servicing Agreement of a certain person named in the Pooling and Servicing Agreement.

The Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar and any agent of any of them may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Trustee, the Securities Administrator, the Master Servicer, the Certificate Registrar or any such agent shall be affected by any notice to the contrary.

As provided in the Pooling and Servicing Agreement, this Certificate and the Pooling and Servicing Agreement shall be construed in accordance with and governed by the laws of the State of New York without regard to the conflict of laws principles applied in the State of New York. In the event of any conflict between the provisions of this Certificate and the Pooling and Servicing Agreement, the Pooling and Servicing Agreement shall be controlling.

The Trustee with cause, may upon at least 60 days’ notice remove and discharge the Custodian from the performance of its duties under this Custodial Agreement by written notice from the Trustee to the Custodian.

In case at any time a successor Custodian shall cease to be eligible in accordance with the provisions of this Section 12, such successor Custodian shall resign immediately and be replaced as specified in the previous paragraph.

(v)           The duties and obligations of the Custodian shall only be such as are expressly set forth in this Agreement or as set forth in a written amendment to this Agreement executed by the parties hereto or their successors and assigns.

In no event shall the Custodian have any responsibility to ascertain or take action except as expressly provided herein.

(vii)         The Custodian may consult with counsel selected by the Custodian with regard to legal questions arising out of or in connection with this Agreement, and the advice or opinion of such counsel shall be full and complete authorization and protection in respect of any action reasonably taken, omitted or suffered by the Custodian in good faith and in accordance therewith.

17

(viii)        No provision of this Agreement shall require the Custodian to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights and powers, if, in its sole judgment, it shall believe that repayment of such funds or adequate indemnity against such risk or liability is not assured to it.

(ix)          The Custodian shall have no duty to ascertain whether or not each amount or payment has been received by the Trustee or any third person.

(x)           Any written instructions provided to the Custodian by a Servicer in accordance with this Agreement shall be deemed to be provided by the appropriate Servicer.

(xii)          The Custodian may engage one or more nationally recognized third parties to perform recording services and document delivery services and any other third party as requested or directed by the Trustee in connection with the Custodian's duties hereunder, and shall not be responsible for the actions or non-actions of such third parties so long as the Custodian is not negligent in selecting such third parties; provided, however, that such appointment shall not relieve the Custodian from performance of its duties hereunder.

(xiii)         In no event shall Custodian be liable for any error of judgment made in good faith by an officer or officers of Custodian unless it shall be conclusively determined by a court of competent jurisdiction that Custodian was negligent in ascertaining the pertinent facts.

This Notice is to inform you that the prior owner of your loan has sold your loan (described below) to the new owner identified below on December 23, 2014.

The servicer (identified below) acts on behalf of the new owner to handle the ongoing administration of your loan, including the collection of mortgage payments. Please continue to send your mortgage payments as directed by the servicer, and NOT to the new owner. Payments sent to the new owner instead of the servicer may result in late charges on your loan and your account becoming past due. Neither the new owner nor the servicer is responsible for late charges or other consequences of any misdirected payment.

SHOULD YOU HAVE ANY QUESTIONS REGARDING YOUR LOAN, PLEASE CONTACT THE SERVICER USING THE CONTACT INFORMATION SET FORTH BELOW. The servicer is authorized to handle routine inquiries and requests regarding your loan and, if necessary, to inform the new owner of your request and communicate to you any decision with respect to such request. **
