Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Base Indenture, they may, but need not, be consolidated and form one instrument.

Section 1.5. Acts of Noteholders.

(a)Any request, demand, authorization, direction, notice, consent, waiver or other action (each, an “Action”) provided by this Base Indenture to be given or taken by Noteholders of any Class may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Noteholders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such Action will become effective when such instrument or instruments are delivered to the Indenture Trustee, and, where it is hereby expressly required, to the Issuer. Such instrument or instruments and any such record (and the Action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Noteholders signing such instrument or instruments and so voting at any meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Note, will be sufficient for any purpose of this Base Indenture and (subject to Section 11.1) conclusive in favor of the Indenture Trustee and the Issuer, if made in the manner provided in this Section 1.5.

(b)The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness to such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by an officer of a corporation or a member of a partnership, on behalf of such corporation or partnership, such certificate or affidavit will also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the person executing the same, may also be proved in any other manner which the Indenture Trustee deems sufficient.

(c)The ownership of Notes will be proved by the Note Register.

Any notice given or Action taken by a Noteholder or its agents with regard to different parts of such principal amount pursuant to this paragraph shall have the same effect as if given or taken by separate Noteholders of each such different part.

appointed in writing, any Action provided in this Base Indenture to be made, given or taken by a Noteholder, and a Depository that is the Noteholder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in or security entitlements to any such Global Note through such Depository’s standing instructions and customary practices.

(g)The Issuer may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in or security entitlements to any Global Note held by a Depository entitled under the procedures of such Depository to make, give or take, by a proxy or proxies duly appointed in writing, any Action provided in this Base Indenture to be made, given or taken by Noteholders. If such a record date is fixed, the Noteholders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such Action, whether or not such Noteholders remain Noteholders after such record date. No such Action shall be valid or effective if made, given or taken more than ninety (90) days after such record date.

(b)Where this Base Indenture provides for notice to or consent from any Note Rating Agency, such notice or consent will only be required to the extent that any Outstanding Notes are then

currently being rated at the request of NSM, and as specified in the related Indenture Supplement, and if no Outstanding Notes are being so rated, including in the event ratings unsolicited by NSM are being issued, such notice or consent provisions shall be of no force or effect. In the event that an Indenture Supplement provides that one or more Classes obtain a rating, any notice shall be sufficient for every purpose hereunder (except with respect to notices to the Indenture Trustee of an Event of Default as provided in Section 3.3 or Section 8.1) if in writing (which shall include electronic transmission) and personally delivered, express couriered, electronically transmitted or mailed by registered or certified mail, addressed to it at the address set forth in the related Indenture Supplement. Failure to give such notice will not affect any other rights or obligations created hereunder and will not under any circumstance constitute an Adverse Effect.

Section 1.7. Notices to Noteholders; Waiver.

(a)Where this Base Indenture, any Indenture Supplement or any Note provides for notice to registered Noteholders of any event, such notice will be sufficiently given (unless expressly provided otherwise herein, in such Indenture Supplement or in such Note) if in writing and mailed by overnight courier, sent by electronic transmission or personally delivered to each Noteholder of a Note affected by such event, at such Noteholder’s address as it appears in the Note Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Noteholders is given by mail, electronic transmission or delivery, none of the failure to mail, send by electronic transmission or deliver such notice, or any defect in any notice so mailed, to any particular Noteholders will affect the sufficiency of such notice with respect to other Noteholders and any notice that is mailed, sent by electronic transmission or delivered in the manner herein provided shall conclusively have been presumed to have been duly given.

Where this Base Indenture, any Indenture Supplement or any Note provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver will be the equivalent of such notice. Waivers of notice by Noteholders will be filed with the Indenture Trustee, but such filing will not be a condition precedent to the validity of any action taken in reliance upon such waiver.

(b)In case, by reason of the suspension of regular mail service as a result of a strike, work stoppage or otherwise, it will be impractical to mail notice of any event to any Noteholder of a Note when such notice is required to be given pursuant to any provision of this Base Indenture, then any method of notification as will be satisfactory to the Indenture Trustee and the Issuer will be deemed to be a sufficient giving of such notice.

(c)The Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary each agree to accept and act upon instructions or directions pursuant to this Base Indenture or any document executed in connection herewith sent by unsecured email or other similar unsecured electronic methods; provided, however, that the Indenture Trustee shall have received an incumbency certificate (attached hereto as Exhibits C1-C5) listing such person as a person designated to provide such instructions or directions, which incumbency certificate may be amended whenever a person is added or deleted from the listing. If such person elects to give the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary email instructions (or instructions by a similar electronic method) and the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary in its discretion elects

to act upon such instructions, the Indenture Trustee’s, Calculation Agent’s, Paying Agent’s and Securities Intermediary’s reasonable understanding of such instructions, as applicable, shall be deemed controlling.

(d)None of the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary shall be liable for any losses, costs or expenses arising directly or indirectly from the Indenture Trustee’s reliance upon and compliance with such instructions notwithstanding such instructions conflicting with or being inconsistent with a prior written instruction except as a result of their respective willful misconduct, negligence or bad faith. Any Person providing such instructions or directions agrees to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary, including the risk of Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary acting on unauthorized instructions, and the risk of interception and misuse by third parties and acknowledges and agrees that there may be more secure methods of transmitting such instructions than the method(s) selected by it and agrees that the security procedures (if any) to be followed in connection with its transmission of such instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances.

(A)NSM may at any time designate any Participation Certificates as additional Participation Certificates to be sold to the Issuer under the PC Repurchase Agreement, whereupon such Participation Certificate shall be added to the Collateral for purposes of this Base Indenture if (1) the Administrative Agent (in its sole discretion) has approved such Participation Certificate for addition and (2) written notice of such addition has been provided to the Note Rating Agencies for the Outstanding Notes. Prior to the addition of any Participation Certificates, as provided in this Section 2.1(b), the Administrator must certify to the Indenture Trustee in writing that it has filed all financing statements or amendments to financing statements to ensure that the Indenture Trustee’s Security Interest in any additional Designated PC, and, if applicable, in the related MSRs and Advance Reimbursement Amounts, is perfected and of first priority.

(C)From time to time, Mortgage Loans may be added to the Portfolio and when such Mortgage Loans are added, NSM shall provide an updated schedule of the related Mortgage Loans to the Indenture Trustee and the Administrative Agent, and any

new schedule of the related Mortgage Loans shall automatically become the new updated schedule thereof.

(ii)Removal of the Participation Certificates and Mortgage Loans.

(A)Subject to the prior written consent of Ginnie Mae, NSM may remove: the Excess Spread PC, the P&I Advance PC or the Servicing Advance PC from the Collateral, whereupon such Excess Spread PC, P&I Advance PC or Servicing Advance PC, as applicable, shall no longer constitute Collateral for purposes of this Base Indenture, if NSM shall have repurchased such Participation Certificate for the full NSM Repurchase Price and such NSM Repurchase Price has been deposited into the Collection and Funding Account, for application in accordance with Section 4.5.

(B)In accordance with the Participation Agreement, NSM may cause the removal of the Mortgage Loans underlying a Participation Certificate, whereupon such MSRs relating to such Mortgage Loans shall no longer constitute Collateral for purposes of this Base Indenture; provided, that NSM shall have repurchased such MSRs relating to such Mortgage Loans for the full NSM Repurchase Price and shall have deposited such NSM Repurchase Price into the Collection and Funding Account, for application in accordance with Section 4.5.

(C)If any Participation Certificates are no longer Collateral, the Administrator shall update the Participation Certificate Schedule and furnish it to the Indenture Trustee, and the most recently furnished schedule shall be maintained by the Indenture Trustee as the definitive Participation Certificate Schedule.

(D)If any Mortgage Loans are removed from the Participation Agreement, NSM shall provide an updated schedule of the MSR Mortgage Pools to the Indenture Trustee and the Administrative Agent within ten (10) Business Days of such removal, and any new schedule of the MSR Mortgage Pools shall automatically become the new updated schedule thereof.

(c)Protection of Transfers to, and Back-up Security Interests of Issuer. The Administrator shall take all actions as may be necessary to ensure that the Trust Estate is Granted to the Indenture Trustee pursuant to this Base Indenture.

In addition, and without limiting the generality of the foregoing, the Administrator, at its own expense at the reasonable request of the Administrative Agent, shall prepare and forward for filing, or shall cause to be forwarded for filing, all filings necessary to maintain the effectiveness of any original filings necessary under the relevant UCC to perfect and maintain the first priority status of the Indenture Trustee’s security interest in the Trust Estate, including (i) continuation statements, and (ii) such other statements as may be occasioned by (A) any change of name of any of NSM or the Issuer,

(B) any change of location of the jurisdiction of any of NSM or the Issuer, (C) any transfer of any interest of NSM or the Issuer in any item in the Trust Estate or (D) any change under the applicable UCC or other applicable laws.

Section 2.2. Asset Files.

(a)Indenture Trustee. The Indenture Trustee agrees to hold, in trust on behalf of the Secured Parties, upon the execution and delivery of this Base Indenture, the following documents relating to each Participation Certificate:

(v)any other documentation provided for in any Indenture Supplement;

provided that the Indenture Trustee shall have no responsibility to ensure the validity or sufficiency of the Participation Certificates.

(i)a copy of the related Participation Certificate and each amendment and modification thereto;

(ii)any documents other than those identified in Section 2.2(a) received from or made available by the Servicer, securities administrator or other similar party in respect of such Participation Certificate; and

(iii)any and all other documents that the Issuer, the Servicer or NSM, as the case may be, shall keep on file, in accordance with its customary procedures, relating to such Participation Certificate.

(c)Delivery of Updated Participation Certificate Schedule. The Administrator shall deliver to the Indenture Trustee an updated Schedule 1 prior to the addition, modification or deletion of any Participation Certificate as Collateral or modification and the Indenture Trustee shall hold the most recently delivered version as the definitive Schedule 1.

(d)Marking of Records. The Administrator shall ensure that, from and after the time of the sale and/or contribution of the Participation Certificates to the Issuer under the PC Repurchase Agreement and the Grant thereof to the Indenture Trustee pursuant to this Base Indenture, any records (including any computer records and back up archives) maintained by or on behalf of the Servicer that refer to any Participation Certificate indicate clearly the interest of the Issuer and the Security Interest of the Indenture

Trustee in such Participation Certificate and that such Participation Certificate is owned by the Issuer and subject to the Indenture Trustee’s Security Interest. Indication of the Issuer’s ownership of a Participation Certificate and the Security Interest of the Indenture Trustee shall be deleted from or modified on such records when, and only when, such Participation Certificate has been paid in full, repurchased, or assigned by the Issuer and released by the Indenture Trustee from its Security Interest.

Section 2.3. Duties of Custodian with Respect to the Asset Files.

(a)Safekeeping. The Indenture Trustee or the Administrator, in its capacity as custodian (each, a “Custodian”) pursuant to Section 2.2(b), shall hold the portion of the Asset Files that it is required to maintain under Section 2.2 in its possession from time to time for the use and benefit of all present and future Noteholders, and maintain such accurate and complete accounts, records and computer systems pertaining to each Asset File as shall enable the Calculation Agent and the Indenture Trustee to comply with this Base Indenture. Each Custodian shall promptly report to the Issuer any failure on its part to hold the Asset Files and maintain its accounts, records and computer systems as herein provided and promptly take appropriate action to remedy any such failure. The Indenture Trustee shall have no responsibility or liability for any actions or omissions of the Administrator in its capacity as Custodian or otherwise.

(b)Custodian. NSM, as Repo Seller, the Issuer and the Administrative Agent each confirm, and each Noteholder is deemed to confirm, that it is treating Citibank, in its capacity as a Custodian, as holding each original Participation Certificate as a “custodian” on behalf of the Issuer as a “customer” in connection with a “securities contract” (as each such term is used in Section 101(22) of the Bankruptcy Code), and each such Person confirms (or is deemed to confirm, in the case of the Noteholders) that in such capacity Citibank is serving as a “financial institution” (as defined in Section 101(22) of the Bankruptcy Code). Citibank confirms that it is a “commercial bank” (as such term is used in such Section 101(22) of the Bankruptcy Code) and acknowledges such treatment by such Persons.

(c)Maintenance of and Access to Records. Each Custodian shall maintain each portion of the Asset File that it is required to maintain under this Base Indenture at its offices at the Corporate Trust Office (in the case of the Indenture Trustee) or 8950 Cypress Waters, Coppell, Texas 75019 (in the case of the Servicer) as the case may be, or at such other office as shall be specified to the Indenture Trustee and the Issuer by thirty (30) days’ prior written notice. The Administrator shall take all actions necessary, or reasonably requested by the Administrative Agent, the Majority Noteholders of all Outstanding Notes or the Indenture Trustee, to amend any existing financing statements and continuation statements, and file additional financing statements to further perfect or evidence the rights, claims or security interests of the Indenture Trustee under any of the Transaction Documents (including the rights, claims or security interests of the Issuer under the PC Repurchase Agreement which have been assigned to the Indenture Trustee). The Indenture Trustee and the Administrator, in their capacities as Custodian(s), shall make available to the Issuer, the Calculation Agent, the Administrative Agent, any group of Interested Noteholders and the Indenture Trustee (in the case of the Administrator) or their duly authorized representatives, attorneys or auditors the portion of the Asset Files that it is required to maintain under this Base Indenture and the accounts, books and records maintained by the Indenture Trustee or the Administrator with respect thereto as promptly as reasonably practicable following not less than two (2) Business Days’ prior written notice for examination during normal business hours and in a manner that does not unreasonably interfere with such Person’s ordinary conduct of business.

Neither the Custodian nor any of its directors, officers or employees shall be liable to anyone for any error of judgment, or for any act done or step taken or omitted to be taken by it (or any of its directors, officers of employees), or for any mistake of fact or law, or for anything which it may do or refrain from doing in connection herewith, unless such action constitutes gross negligence, willful misconduct or bad faith of the Custodian. Knowledge or information acquired by Citibank in its capacity as Custodian hereunder shall not be imputed to Citibank in any other capacity in which it may act hereunder or to any affiliate of Citibank and vice versa. The Custodian shall be deemed to have the same rights, immunities and protections as the Indenture Trustee hereunder, except that the Custodian shall not be subject to a prudent person standard under any circumstances.

Section 2.4. Application of Trust Money.

All money deposited with the Indenture Trustee or the Paying Agent pursuant to Section 4.2 shall be held in trust and applied by the Indenture Trustee or the Paying Agent, as the case may be, in accordance with the provisions of the Notes and this Base Indenture, to the payment to the Persons entitled thereto, of the principal, interest, fees, costs and expenses (or payments in respect of the Funding Amount or other amount) for whose payment such money has been deposited with the Indenture Trustee or the Paying Agent.

The Indenture Trustee shall not be required to make available via its website any information that in its judgment is confidential, may include any

In addition, the Indenture Trustee shall have no liability for the failure to include or post any information that it has not actually received or is not in a form or format that will allow it to post any such information on its website.

Notwithstanding any provision herein to the contrary, including Sections 3.1, 3.2 and 3.5 hereof, the Indenture Trustee, the Administrative Agent and any other party hereto shall not deliver, or make available, the Market Value Information to any Noteholder of any Series of Term Notes prior to the occurrence, or following the cure or waiver, of an Event of Default; and prior to the occurrence, or during the continuation, of an Event of Default, any Determination Date Report, Interim Payment Date Report, Payment Date Report made available to any Noteholders of Series of Outstanding Term Notes by Citibank, in any capacity, pursuant to this Section 3.5 or otherwise hereunder shall be redacted to remove any Market Value Information prior to being made so available.

Article IV
The Trust Accounts; Payments

The Indenture Trustee shall establish and maintain, or cause to be established and maintained, (i) the Trust Accounts, each of which shall be an Eligible Account, for the benefit of the Secured Parties, (ii) an Expense Reserve Account, which shall be an Eligible Account, for the benefit of the Indenture Trustee and the MSR Valuation Agent and (iii) a Credit Manager Expense Reserve Account, which shall be an Eligible Account in the name of the Indenture Trustee, for the benefit of the Credit Manager. All amounts held in the Trust Accounts and the Credit Manager Expense Reserve Account shall remain uninvested. The taxpayer identification number associated with each of the Trust Accounts or the Credit Manager Expense Reserve Account, as applicable, shall be that of the Issuer, and the Issuer shall report for federal, state and local income tax purposes their respective portions of the income, if any, earned on funds in the relevant Trust Account or the Credit Manager Expense Reserve Account, as applicable. The Administrator hereby acknowledges that all amounts on deposit in each Trust Account (excluding investment earnings on deposit in the Trust Accounts) are held in trust by the Indenture Trustee for the benefit of the Secured Parties, subject to any express rights of the Issuer set forth herein, and shall remain at all times during the term of this Base Indenture under the sole dominion and control of the Indenture Trustee. The Administrator hereby acknowledges that all amounts on deposit in the Credit Manager Expense Reserve Account (excluding investment earnings on deposit in the Credit Manager Expense Reserve Account) are held in trust by the Indenture Trustee for the benefit of the Credit Manager and shall remain at all times during the term of this Base Indenture under the sole dominion and control of the Indenture Trustee.

So long as the Indenture Trustee complies with the provisions of this Section 4.1, the Indenture Trustee shall not be liable for the selection of investments or for investment losses incurred thereon by reason of investment performance, liquidation prior to stated maturity or otherwise in any Trust Account or the Credit Manager Expense Reserve Account. The Indenture Trustee shall have no liability in respect of losses incurred in any Trust Account or the Credit Manager Expense Reserve Account as a result of the liquidation of any investment prior to its stated maturity or the failure to be provided with timely written investment direction.

In order to comply with the laws, rules, regulations and executive orders in effect from time to time applicable to banking institutions, including those relating to the funding of terrorist activities and money laundering, including Section 326 of the USA Patriot Act of the United States (“Applicable Law”), the Indenture Trustee is required to obtain, verify, record and update certain information relating to individuals and entities which maintain a business relationship with the Indenture Trustee. Accordingly, each of the parties agrees to provide to the Indenture Trustee upon its request from time to time such identifying information and documentation as may be available for such party in order to enable the Indenture Trustee to comply with Applicable Law.

All parties to this Base Indenture agree, and each Noteholder of each Series by its acceptance of the related Note will be deemed to have agreed, that such Noteholder shall have no claim or interest in the amounts on deposit in any Trust Account created under this Base Indenture or any related Indenture Supplement related to an unrelated Series except as expressly provided herein or therein.

The Indenture Trustee or its Affiliates are permitted to receive additional compensation that could be deemed to be for the Indenture Trustee’s economic self-interest for (a) serving as investment adviser, administrator, shareholder, servicing agent with respect to certain of the Permitted Investments, (b) using Affiliates to effect transactions in certain Permitted Investments and (c) effecting transactions in certain Permitted Investments.

The State of New York is the Securities Intermediary’s jurisdiction for purposes of the UCC, and the laws of the State of New York are applicable to all issues specified in Article 2(1) of the Hague Securities Convention. This Base Indenture is the only “account agreement” in respect of the Trust Accounts.

Section 4.2. Collections and Disbursements of MBS Portfolio Collections by Servicer.

(a)Remittance of Collections. The Servicer shall remit all Advance Reimbursement Amounts attributable to the Participation Agreement (but only to the extent that such funds are payable to Issuer free and clear of Ginnie Mae’s rights or other restrictions on transfer set forth in such Ginnie Mae Contract) to the Collection and Funding Account within two (2) Business Days after collection and identification thereof. The Servicer shall remit all Collections on the Excess Spread PC for any calendar month to the Collection and Funding Account no later than two (2) Business Days before the Payment Date (or, if (i) an Event of Default is continuing or (ii) at any time during which funds on deposit in the Collection and Funding Account are less the Required Available Funds, no later than two (2) Business Days after receipt and identification thereof). Advance Reimbursement Amounts shall be allocated to the Advance Reimbursement Available Funds Subaccount of the Collection and Funding Account. All other Collections shall be allocated to the Servicing Spread Available Funds Subaccount of the Collection and Funding Account.

(b)Payment Dates. On each Payment Date (and, with respect to MBS Advance Reimbursement Amounts, on the third Business Day of each week other than the week of a Payment Date

or Interim Payment Date), the Indenture Trustee shall transfer from the Collection and Funding Account (and, with respect to MBS Advance Reimbursement Amounts, all such amounts on deposit in the Advance Reimbursement Available Funds Subaccount) to the Note Payment Account all funds then on deposit therein. Except in the case of Redemption Amounts, which may be remitted by the Issuer directly to the Note Payment Account, none of the Servicer, the Administrator, the Issuer, the Calculation Agent nor the Indenture Trustee shall remit to the Note Payment Account, and each shall take all reasonable actions to prevent other Persons from remitting to the Note Payment Account, amounts which do not constitute payments, collections or recoveries received, made or realized in respect of the Participation Certificates or the initial cash deposited by the Noteholders with the Indenture Trustee on the date hereof, and the Indenture Trustee will return to the Issuer or the Servicer any such amounts upon receiving written evidence reasonably satisfactory to the Indenture Trustee that such amounts are not a part of the Trust Estate.

(c)Delegated Authority to Make MBS Advances. The Servicer hereby irrevocably appoints the Noteholder(s) of any Outstanding MBS Advance VFN with the authority (but no obligation) to make any MBS Advance on the Servicer’s behalf to the extent the Servicer fails to make any required payments on the related MBS when required to do so pursuant to the Ginnie Mae Contract. Any payment of MBS Advances by Noteholders of MBS Advance VFNs shall constitute a draw on such VFN and shall increase its VFN Principal Balance by the amount of such draw.

(d)Maximum Distribution Amount. So long as no Event of Default has occurred and is continuing, one (1) time per month following delivery of the Market Value Report but prior to the twenty-third (23rd) day of each month (or, if such day is not a Business Day, the Business Day following such day), the Administrator may prepare a distribution certificate, which shall be signed by the Administrator, pursuant to which it will calculate the Maximum Distribution Amount for the related Collection Period (the “Maximum Distribution Certificate”) and may direct the Indenture Trustee to distribute the Maximum Distribution Amount to NSM, as the holder of the Owner Trust Certificate. The Indenture Trustee may conclusively rely on such direction and need not verify or recalculate the Maximum Distribution Amount. By no later than 3:00 p.m. New York City time on the Business Day following receipt of the Maximum Distribution Certificate, the Indenture Trustee shall pay to NSM as holder of the Owner Trust Certificate the Maximum Distribution Amount. For the avoidance of doubt, the Administrator, on behalf of the Issuer, shall not be permitted to submit a VFN Note Balance Adjustment Request pursuant to Section 4.3(b) after the payment of the Maximum Distribution Amount if giving effect to such VFN Note Balance Adjustment Request would result in the Maximum Distribution Amount being a negative number.

Section 4.3. Fundings.

(a)Funding Certifications. By no later than 1:00 p.m. New York City time on the Business Day prior to each Funding Date (or such other time as may be agreed to from time to time by the Administrator, the Indenture Trustee and the Administrative Agent), the Administrator shall prepare and deliver to the Issuer, the Indenture Trustee, the Calculation Agent and the Administrative Agent (and, on any Interim Payment Date, each applicable VFN Noteholder) a certification (each, a “Funding Certification”) containing a list of each Funding Condition and presenting a “yes” or “no” answer beside each indicating whether such Funding Condition has been satisfied and shall state in writing the amount to be funded on that Funding Date.

(b)VFN Draws, Discretionary Paydowns and Permanent Reductions. With respect to each VFN (other than a MBS Advance VFN):

(i)From time to time, the Collateral Value may increase due to (i) the addition of Mortgage Loans to the MSR Portfolio, (ii) increases in the value of the MSRs that underlie the MSR Portfolio or (iii) increases in the Advance Reimbursement Balance, as applicable. By no later than 1:00 p.m. New York City time on the Business Day prior to any Payment Date or Interim Payment Date during the Revolving Period for such VFN on which any applicable Variable Funding Note Class is Outstanding (or after the Revolving Period but prior to an Event of Default with the consent of the Administrative Agent with respect to any, or all, of the VFNs), the Administrator, on behalf of the Issuer, may deliver, or cause to be delivered, to each Noteholder of such Variable Funding Notes and to the Indenture Trustee a report (a “VFN Note Balance Adjustment Request”) for such upcoming Funding Date, requesting such Noteholders to fund a VFN Principal Balance increase on any Class or Classes of VFNs in the amount(s) specified in such request, which request shall instruct the Indenture Trustee to recognize an increase in the related VFN Principal Balance, but not in excess of the lesser of (x) the related Maximum VFN Principal Balance or (y) the amount that would cause a Borrowing Base Deficiency. The VFN Note Balance Adjustment Request shall also state the amount, if any, of any principal payment to be made on each Outstanding Class of VFNs on the upcoming Interim Payment Date or Payment Date. The amount to be funded shall be based on the change in the related Collateral Value from the most recent Interim Payment Date or Payment Date.

(ii)If the related Funding Certification indicates that all Funding Conditions have been met, the applicable VFN Noteholders of each Series shall fund the VFN Principal Balance for such Series increase by remitting pro rata (based on such Noteholder’s percentage of the related Maximum VFN Principal Balance) the amount stated in the request to the Indenture Trustee by 12:00 p.m. (noon) New York City time on the related Funding Date, whereupon the Indenture Trustee shall adjust its records to reflect the increase of the VFN Principal Balance (which increase shall be the aggregate of the amounts received by the Indenture Trustee from the applicable VFN Noteholders) by the later of (i) 2:00 p.m. New York City time on such Funding Date, or (ii) two hours after the receipt by the Indenture Trustee of such funds from the VFN Noteholders, so long as, after such increase, no Borrowing Base Deficiency will exist, determined based on the VFN Note Balance Adjustment Request and Determination Date Report. The Indenture Trustee shall be entitled to rely conclusively on any VFN Note Balance Adjustment Request and the related Determination Date Report and Funding Certification. The Indenture Trustee shall make available on a password-protected portion of its website to the Issuer or its designee and each applicable VFN Noteholder, notice on such Funding Date as reasonably requested by the Issuer of any increase in the VFN Principal Balance. The Indenture Trustee shall apply and remit any such payment by the VFN Noteholders toward the payment of the related Funding Amounts as described in Section 4.3(c). If any VFN Noteholder in respect of a Series does not fund its share of a requested VFN Draw, one or more other VFN Noteholders of such Series may fund all or a portion of such draw, but no other VFN Noteholder shall have any obligation to do so. Draws on VFNs of different Classes within the same Series need not be drawn pro rata relative to each other. Any draws under any VFNs shall be used only to purchase new Participation Certificates and to fund the creation or acquisition of the servicing rights related to additional Mortgage Pools under existing Participation Certificates (in the case of MSR

VFNs), to fund the acquisition of additional Advance Reimbursement Amounts related to the Portfolio Mortgage Loans (in the case of SPIA VFNs) or to increase the value of the related Participation Certificates pursuant to the PC Repurchase Agreement in a manner that would not be in violation of any term hereof (including in a manner that would result in a material adverse United States federal income tax consequence to the Trust Estate or any Noteholders).

(a)Series Reserve Account.

(i)Pursuant to Section 4.1, the Indenture Trustee shall, within five (5) Business Days of receipt of a written request from the Issuer, establish and maintain a Series Reserve Account or Trust Accounts for each Series, each of which shall be an Eligible Account, for the benefit of the Secured Parties of such Series. If any such account loses its status as an Eligible Account, the funds in such account shall be moved to an account that qualifies as an Eligible Account within thirty (30) days. On or prior to the Issuance Date for each Series, the Issuer shall cause an amount equal to the related Series Reserve Required Amount(s), if applicable, to be deposited into the related Series Reserve Account(s). Thereafter, on each Payment Date and Interim Payment Date, the Indenture Trustee shall withdraw the Servicing Spread Available Funds or Advance Reimbursement Available Funds, as applicable, from the Note Payment Account and deposit them into each such related Series Reserve Account pursuant to, and to the extent required by, Section 4.5(a) and the related Indenture Supplement.

(ii)On each Payment Date, an amount equal to the aggregate of amounts described in clauses (i), (ii) and (iii) of Section 4.5(a)(1), clauses (i) and (ii) of Section 4.5(a)(2) or clauses (i), (ii) and (iii)(A) through (B) of Section 4.5(a)(3) allocable to the related Series, as appropriate, and which is not payable out of the related Available Funds or the related Series Available Funds, as applicable, due to an insufficiency of such Available Funds or Series Available Funds, as applicable, shall be withdrawn from (x) the related Series Reserve Account (other than any Series Reserve Account related to a SPIA VFN) by the Indenture Trustee and remitted to the Note

Payment Account for payment in respect of the related Class’ allocable share of such items as described in Section 4.5(a)(1),

(y) the related Series Reserve Account related to a SPIA VFN by the Indenture Trustee and remitted to the Note Payment Account for payment in respect of the related Class’ allocable share of such items as described in Section 4.5(a)(2) or (z) the related Indenture Supplement. On any Payment Date on which amounts are withdrawn from such Series Reserve Account pursuant to Section 4.5(a)(1) or Section 4.5(a)(2), no funds shall be withdrawn from the Collection and Funding Account (or from the Note Payment Account for deposit into the Collection and Funding Account) to pay Funding Amounts or amounts to the Issuer pursuant to Section 4.3 with respect to any MSR VFN or any SPIA VFN, respectively, if, after giving effect to the withdrawals described in the preceding sentences, the amount then standing to the credit of the related Series Reserve Account is less than the related Series Reserve Required Amount, if applicable. All Collections received in the Collection and Funding Account shall be deposited into the related Series Reserve Accounts until the amount on deposit in each Series Reserve Account equals the related Series Reserve Required Amount, if applicable, as described in Section 4.5 and the related Indenture Supplement. For purposes of the foregoing, the portion of any such fees and expenses payable under Section 4.5(a)(1)(i) or (ii) shall equal the related Series Allocation Percentage of the amounts payable under such clause.

(iii)If on any Payment Date the amount on deposit in a Series Reserve Account is equal to or greater than the aggregate Note Balance for the related Series (after payment on such Payment Date of the amounts described in Section 4.5) the Indenture Trustee will withdraw from such Series Reserve Account the aggregate Note Balance for such Series and remit it to the Noteholders of the Notes of such Series in reduction of the aggregate Note Balance for all Classes of Notes of such Series that are Outstanding. On the Stated Maturity Date for the latest maturing Class in a Series, the balance on deposit in the related Series Reserve Account shall be applied as a principal payment on the Notes of that Series to the extent necessary to reduce the aggregate Note Balance for that Series to zero. On any Payment Date after payment of principal on the Notes and when no Event of Default has occurred, the Indenture Trustee shall withdraw from each Series Reserve Account the amount by which the balance of the Series Reserve Account exceeds the related Series Reserve Required Amount, if applicable, and pay such amount to NSM as holder of the Owner Trust Certificate.

(iv)Amounts held in a Series Reserve Account shall remain uninvested.

(v)On any Payment Date, after payment of all amounts pursuant to Section 4.5(a), during the Full Amortization Period, the Indenture Trustee shall withdraw from each Series Reserve Account the amount by which the amount standing to the credit of such Series Reserve Account exceeds the related Series Reserve Required Amount, if applicable, and shall apply such excess to reduce the Note Balances of the Notes of the related Series, pursuant to Section 4.5. Such principal payment shall be made in accordance with the terms and provisions of the related Indenture Supplement. On any Payment Date following the payment in full of all principal payable in respect of the related Series or Class of Notes, the Indenture Trustee shall withdraw any remaining amounts from the related Series Reserve Account and distribute it to NSM as holder of the Owner Trust Certificate. Amounts paid to NSM or its designee pursuant to the preceding sentence shall be released from the Security Interest.

(vi)If on any Funding Date, the amount on deposit in one or more Series Reserve Accounts is less than the related Series Reserve Required Amounts, if applicable, then the Administrator may direct the Indenture Trustee to transfer from the Collection and Funding Account to such Series Reserve Accounts an amount equal to the amount by which the respective Series Reserve Required Amounts, if applicable, exceed the respective amounts then on deposit in the related Series Reserve Accounts.

(vii)Any funds on deposit in any Series Reserve Account are to be applied to make any required payments in respect of the related Series or Class of Notes only, and no other Series or Class of Notes shall have any interest or claim against such amounts on deposit. Notwithstanding the foregoing, if any Series or Class of Notes is deemed to have an interest or claim on the funds on deposit in the Series Reserve Account established for another Series, it shall not receive any amounts on deposit in such Series Reserve Account unless and until the Series or Class of Notes related to such Series Reserve Account are paid in full and are no longer Outstanding. The provisions of this Section 4.6(a)(vii) constitute a “subordination agreement” for purposes of Section 510(a) of the Bankruptcy Code.

(b)Expense Reserve Account.

(i)Pursuant to Section 4.1, the Indenture Trustee shall establish and maintain an Expense Reserve Account, which shall be an Eligible Account, for the benefit of the Indenture Trustee and the MSR Valuation Agent. If any such account loses its status as an Eligible Account, the funds in such account shall be moved to an account that qualifies as an Eligible Account within thirty (30) days. On each Payment Date and Interim Payment Date, the Indenture Trustee shall withdraw Servicing Spread Available Funds (and during the Full Amortization Period, all Available Funds) from the Note Payment Account and deposit them into the Expense Reserve Account pursuant to, and to the extent required by Section 4.5(a).

(ii)On each Payment Date, an amount equal to the aggregate of amounts described in clause (i) of Section 4.5(a)(2) which is not payable out of Series Available Funds due to an insufficiency of Series Available Funds shall be withdrawn from the Expense Reserve Account by the Indenture Trustee and remitted to the Note Payment Account for payment in respect of the related Class’ allocable share of such items as described in Section 4.5(a). On any Payment Date on which amounts are withdrawn from the Expense Reserve Account pursuant to Section 4.5(a), no funds shall be withdrawn from the Collection and Funding Account (or from the Note Payment Account for deposit into the Collection and Funding Account) to pay Funding Amounts with respect to the MSR VFN or amounts to the Issuer pursuant to Section 4.3 if, after giving effect to the withdrawals described in the preceding sentences, the amount then standing to the credit of the Expense Reserve Account is less than the Expense Reserve Required Amount. If the Expense Reserve Required Amount is greater than $0, all Collections received in the Collection and Funding Account related to Servicing Spread Available Funds (and during the Full Amortization Period, all Available Funds) shall be deposited into the Expense Reserve Account until the amount on deposit in the Expense Reserve Account equals the Expense Reserve Required Amount, as described in Section 4.5.

(iii)Amounts held in the Expense Reserve Account shall remain uninvested.

(iv)On any Payment Date, after payment of all amounts pursuant to Section 4.5(a), during the Full Amortization Period, the Indenture Trustee shall withdraw from the Expense Reserve Account the amount by which the amount standing to the credit of the Expense Reserve Account exceeds the Expense Reserve Required Amount, if applicable, and shall apply such excess to reduce the Note Balances of the Notes of all Series, pursuant to Section 4.5. Such principal payment shall be made in accordance with the terms and provisions of the related Indenture Supplement. On any Payment Date following the payment in full of all principal payable in respect of all Series or Classes of Notes and the payment in full of all amounts payable to the Indenture Trustee and the MSR Valuation Agent, the Indenture Trustee shall withdraw any remaining amounts from the Expense Reserve Account and distribute it to NSM as holder of the Owner Trust Certificate. Amounts paid to NSM or its designee pursuant to the preceding sentence shall be released from the Security Interest.

(v)If on any Funding Date, the amount on deposit in the Expense Reserve Accounts is less than the Expense Reserve Required Amount, if applicable, then the Administrator may direct the Indenture Trustee to transfer from the Collection and Funding Account to the Expense Reserve Account from Servicing Spread Available Funds (and during the Full Amortization Period, all Available Funds) on deposit therein, an amount equal to the amount by which the Expense Reserve Required Amount exceeds the amounts then on deposit in the Expense Reserve Account.

(c)Credit Manager Expense Reserve Account.

(i)Pursuant to Section 4.1, the Indenture Trustee shall establish and maintain a Credit Manager Expense Reserve Account, which shall be an Eligible Account in the name of the Indenture Trustee, for the benefit of the Credit Manager for payment of amounts due the Credit Manager on any Payment Date. It is the intent of the parties that the Credit Manager Expense Reserve Account be an account of the Indenture Trustee, and not an account of the Issuer. Nonetheless, to the extent that the Issuer has any rights in the Credit Manager Expense Reserve Account, the Issuer hereby grants to the Indenture Trustee for the benefit of the Credit Manager, to secure the payment of all amounts owning to the Credit Manager pursuant to this Indenture, a security interest in all of its right, title, and interest, if any, whether now owned or hereafter acquired, in, to, and under, the Credit Manager Expense Reserve Account, all money and other property held therein, and all proceeds thereof. If any such account loses its status as an Eligible Account, the funds in such account shall be moved to an account that qualifies as an Eligible Account within thirty (30) days. Thereafter, on each Payment Date and Interim Payment Date, the Indenture Trustee shall withdraw Servicing Spread Available Funds (and during the Full Amortization Period, all Available Funds) from the Note Payment Account and deposit them into the Credit Manager Expense Reserve Account pursuant to, and to the extent required by Section 4.5(a).

Reserve Account pursuant to Section 4.5(a), no funds shall be withdrawn from the Collection and Funding Account (or from the Note Payment Account for deposit into the Collection and Funding Account) to pay Funding Amounts with respect to any MSR VFN or amounts to the Issuer pursuant to Section 4.3 if, after giving effect to the withdrawals described in the preceding sentences, the amount then standing to the credit of the Credit Manager Expense Reserve Account is less than the Credit Manager Expense Reserve Required Amount. All Collections received in the Collection and Funding Account related to Servicing Spread Available Funds (and during the Full Amortization Period, all Available Funds) shall be deposited into the Credit Manager Expense Reserve Account until the amount on deposit in the Credit Manager Expense Reserve Account equals the Credit Manager Expense Reserve Required Amount, as described in Section 4.5.

(iii)Amounts held in the Credit Manager Expense Reserve Account shall remain uninvested.

(iv)Subject to Section 4.6(c)(v) hereof, on any Payment Date following the payment in full of all principal payable in respect of all Series or Classes of Notes and the payment in full of all amounts payable to the Credit Manager, the Indenture Trustee shall withdraw any remaining amounts from the Credit Manager Expense Reserve Account and distribute and allocate them to the Issuer in accordance with the terms hereof. Amounts paid to the Issuer or its designee pursuant to the preceding sentence shall be released from the Security Interest.

(v)Notwithstanding anything herein to the contrary, in the event of the occurrence of any action by Ginnie Mae pursuant to Section 8 of the Acknowledgment Agreement to terminate and extinguish any rights of NSM as servicer, the Indenture Trustee shall continue to maintain the Credit Manager Expense Reserve Account for the benefit of the Credit Manager for three (3) years following payment in full of all Outstanding Notes, to the extent this Base Indenture has not been satisfied and discharged; provided, that if amounts have been withdrawn from the Credit Manager Expense Reserve Account during such three (3) year-period, or the Credit Manager shall have received written notice of a claim arising in connection with its performance or obligations under this Base Indenture and the other Transaction Documents, then the Credit Manager Expense Reserve Account shall continue to be maintained for five (5) years following payment in full of all Outstanding Notes, to the extent this Base Indenture has not been satisfied and discharged.

(vi)If on any Funding Date, the amount on deposit in the Credit Manager Expense Reserve Accounts is less than the Credit Manager Expense Reserve Required Amount, if applicable, then the Administrator may direct the Indenture Trustee to transfer from the Collection and Funding Account to the Credit Manager Expense Reserve Account from Servicing Spread Available Funds (and during the Full Amortization Period, all Available Funds) on deposit therein, an amount equal to the amount by which the Credit Manager Expense Reserve Required Amount exceeds the amounts then on deposit in the Credit Manager Expense Reserve Account.

Section 4.7. Collection and Funding Account.

Pursuant to Section 4.1, the Indenture Trustee shall establish and maintain the Collection and Funding Account, the Advance Reimbursement Available Funds Subaccount and the Servicing Spread

Available Funds Subaccount, each of which shall be an Eligible Account, the funds in such account shall be moved to an account that qualifies as an Eligible Account within thirty (30) days. The Indenture Trustee shall deposit and withdraw Available Funds from the Collection and Funding Account pursuant to, and to the extent required by Section 4.5. The Indenture Trustee shall hold the portion of Available Funds that constitute Advance Reimbursement Available Funds in an account deemed to be a subaccount of the Collection and Funding Account (the “Advance Reimbursement Available Funds Subaccount”). The Indenture Trustee shall hold that portion of Available Funds that constitute Servicing Spread Available Funds in an account deemed to be a subaccount of the Collection and Funding Account (the “Servicing Spread Available Funds Subaccount”).

Amounts held in the Collection and Funding Account, the Advance Reimbursement Available Funds Subaccount and the Servicing Spread Available Funds Subaccount shall remain uninvested.

Section 4.8. Note Payment Account.

(a)Pursuant to Section 4.1, the Indenture Trustee shall establish and maintain the Note Payment Account, which shall be an Eligible Account, for the benefit of the Secured Parties. If the Note Payment Account loses its status as an Eligible Account, the funds in such account shall be moved to an account that qualifies as an Eligible Account within thirty (30) days. The Note Payment Account shall be funded to the extent that (i) the Issuer shall remit to the Indenture Trustee the Redemption Amount for a Class of Notes pursuant to Section 13.1, (ii) the Indenture Trustee shall remit thereto any Available Funds from the Collection and Funding Account pursuant to Section 4.2(b), (iii) the Indenture Trustee shall transfer amounts from an applicable Series Reserve Account pursuant to, and to the extent required by, Section 4.6, and (iv) the Indenture Trustee shall transfer amounts from the Expense Reserve Account pursuant to, and to the extent required by, Section 4.6.

(b)On each Payment Date, an amount equal to the aggregate of amounts described in Section 4.5(a) shall be withdrawn from the Note Payment Account by the Indenture Trustee and remitted to the Noteholders and other Persons or accounts described therein for payment as described in that Section, and upon payments of all sums payable hereunder as described in Section 4.5(a), as applicable, any remaining amounts then on deposit in the Note Payment Account shall be released from the Security Interest and paid to NSM or its designee unless it would cause a Borrowing Base Deficiency.

(c)Amounts held in the Note Payment Account shall remain uninvested.

Section 4.9. Securities Accounts.

(a)Securities Intermediary. The Issuer and the Indenture Trustee hereby appoint Citibank, as Securities Intermediary with respect to the Trust Accounts. The Security Entitlements and all Financial Assets credited to the Trust Accounts, including all amounts, securities, investments, Financial Assets, investment property and other property from time to time deposited in or credited to such account and all proceeds thereof, held from time to time in the Trust Accounts will continue to be held by the Securities Intermediary for the Indenture Trustee for the benefit of the Secured Parties. Upon the termination of this Base Indenture, the Indenture Trustee shall inform the Securities Intermediary of such termination. By acceptance of their Notes or interests therein, the Noteholders and all beneficial owners of Notes shall be deemed to have appointed Citibank, as Securities Intermediary. Citibank hereby accepts such appointment as Securities Intermediary.

(i)With respect to any portion of the Trust Estate that is credited to the Trust Accounts, the Securities Intermediary agrees that:

(A)with respect to any portion of the Trust Estate that is held in deposit accounts, each such deposit account shall be subject to the security interest granted pursuant to this Base Indenture, and the Securities Intermediary shall comply with instructions originated by the Indenture Trustee directing dispositions of funds in the deposit accounts without further consent of the Issuer and otherwise shall be subject to the exclusive custody and control of the Securities Intermediary, and the Securities Intermediary shall have sole signature authority with respect thereto;

(B)any and all property credited to the Trust Accounts shall be treated by the Securities Intermediary as Financial Assets;

(C)any portion of the Trust Estate that is, or is treated as, a Financial Asset shall be physically delivered (accompanied by any required endorsements) to, or credited to an account in the name of, the Securities Intermediary or other eligible institution maintaining any Trust Account in accordance with the Securities Intermediary’s customary procedures such that the Securities Intermediary or such other institution establishes a Security Entitlement in favor of the Indenture Trustee with respect thereto over which the Securities Intermediary or such other institution has “control” (as defined in the UCC); and

(D)it will use reasonable efforts to promptly notify the Indenture Trustee and the Issuer if any other Person claims that it has a property interest in a Financial Asset in any Trust Account and that it is a violation of that Person’s rights for anyone else to hold, transfer or deal with such Financial Asset.

(ii)The Securities Intermediary hereby confirms that (A) each Trust Account is an account to which Financial Assets are or may be credited, and the Securities Intermediary shall, subject to the terms of this Base Indenture treat the Indenture Trustee as entitled to exercise the rights that comprise any Financial Asset credited to any Trust Account, (B) any portion of the Trust Estate in respect of any Trust Account will be promptly credited by the Securities Intermediary to such account, and (C) all securities or other property underlying any Financial Assets credited to any Trust Account shall be registered in the name of the Securities Intermediary, endorsed to the Securities Intermediary or in blank or credited to another securities account maintained in the name of the Securities Intermediary, and in no case will any Financial Asset credited to any Trust Account be registered in the name of the Issuer or the Administrator, payable to the order of the Issuer or the Administrator or specially endorsed to any of such Persons.

(iii)If at any time the Securities Intermediary shall receive an Entitlement Order from the Indenture Trustee directing transfer or redemption of any Financial Asset relating to any Trust Account, the Securities Intermediary shall comply with such Entitlement Order without further consent by the Issuer or the Administrator or any other Person. If at any time the Indenture Trustee notifies the Securities Intermediary in writing that this Base Indenture has been discharged in accordance herewith, then thereafter if the Securities Intermediary shall receive any

order from the Issuer directing transfer or redemption of any Financial Asset relating to any Trust Account, the Securities Intermediary shall comply with such Entitlement Order without further consent by the Indenture Trustee or any other Person.

(iv)In the event that the Securities Intermediary has or subsequently obtains by agreement, operation of law or otherwise a security interest in any Trust Account or any Financial Asset or Security Entitlement credited thereto, the Securities Intermediary hereby agrees that such security interest shall be subordinate to the security interest of the Indenture Trustee. The Financial Assets and Security Entitlements credited to the Trust Accounts will not be subject to deduction, set-off, banker’s lien, or any other right in favor of any Person other than the Indenture Trustee (on behalf of the Secured Parties) in the case of the Trust Accounts.

(v)There are no other agreements entered into between the Securities Intermediary in such capacity, and the Securities Intermediary agrees that it will not enter into any agreement with, the Issuer, the Administrator, or any other Person (other than the Indenture Trustee) with respect to any Trust Account. In the event of any conflict between this Base Indenture (or any provision of this Base Indenture) and any other agreement now existing or hereafter entered into, the terms of this Base Indenture shall prevail.

(vi)The rights and powers granted herein to the Indenture Trustee have been granted in order to perfect its interest in the Trust Accounts and the Security Entitlements to the Financial Assets credited thereto, and are powers coupled with an interest and will not be affected by the bankruptcy of the Issuer, the Administrator or NSM nor by the lapse of time. The obligations of the Securities Intermediary hereunder shall continue in effect until the interest of the Indenture Trustee in the Trust Accounts and in such Security Entitlements, has been terminated pursuant to the terms of this Base Indenture and the Indenture Trustee has notified the Securities Intermediary of such termination in writing.

(b)Definitions; Choice of Law. Capitalized terms used in this Section 4.9 and not defined herein shall have the meanings assigned to such terms in the New York UCC. For purposes of Section 8-110(e) of the New York UCC, the “securities intermediary’s jurisdiction” shall be the State of New York. The Securities Intermediary, the Administrator and the Issuer agree that they will not change the applicable law in force with respect to issues referred to in Article 2(1) of the Hague Securities Convention to a state other than the State of New York.

(c)Limitation on Liability. None of the Securities Intermediary or any director, officer, employee or agent of the Securities Intermediary shall be under any liability to the Indenture Trustee or the Noteholders for any action taken, or not taken, in good faith pursuant to this Base Indenture, or for errors in judgment; provided, however, that this provision shall not protect the Securities Intermediary against any liability to the Indenture Trustee or the Noteholders which would otherwise be imposed by reason of the Securities Intermediary’s willful misconduct, bad faith or negligence in the performance of its obligations or duties hereunder. The Securities Intermediary and any director, officer, employee or agent of the Securities Intermediary may rely in good faith on any document of any kind which, on its face, is properly executed and submitted by any Person respecting any matters arising hereunder. The Securities Intermediary shall be under no duty to inquire into or investigate the validity, accuracy or content of such document.

(d)Representations, Warranties and Covenants of the Securities Intermediary. The Securities Intermediary represents and warrants that, as of the date hereof, the Securities Intermediary has a physical office in the United States and is engaged in a business or other regular activity of maintaining securities accounts. The Securities Intermediary agrees that, at all times while this Indenture is in effect, it shall maintain a physical office in the United States that satisfies the criteria set forth in Article 4(1)(a) or (b) of the Hague Securities Convention.

Section 4.10. Notice of Adverse Claims.

Except for the claims and interests of the Secured Parties in the Trust Accounts, the Securities Intermediary has no actual knowledge of any claim to, or interest in, any Trust Account or in any financial asset credited thereto. If any Person asserts any Adverse Claim (including any writ, garnishment, judgment, warrant of attachment, execution or similar process) against any Trust Account or in any financial asset carried therein of which a Responsible Officer of the Securities Intermediary has actual knowledge, the Securities Intermediary will promptly notify the Noteholders, the Indenture Trustee and the Issuer thereof.

Section 4.11. No Gross Up.

No Person, including the Issuer, shall be obligated to pay any additional amounts to the Noteholders or Note Owners as a result of any withholding or deduction for, or on account of, any present or future taxes, duties, assessments or governmental charges.

Upon the occurrence of an Early Amortization Event, the Revolving Period for all Classes and Series of the Notes shall automatically terminate and the Early Amortization Period for all Outstanding Notes shall commence without further action on the part of any Person, unless, together, the Majority Noteholders of all Outstanding Notes that are not Variable Funding Notes and the Majority Noteholders for each Series of Variable Funding Notes that are Outstanding, plus the Administrative Agent, notify the Indenture Trustee, Ginnie Mae and the Credit Manager that either (i) they have waived the occurrence of such Early Amortization Event and consent to the continuation of the Revolving Period for each Series of Outstanding Notes that is still in its Revolving Period or (ii) they acknowledge that the Early Amortization Event has been cured and consent to the continuation of the Revolving Period for each Series of Outstanding Notes that is still in its Revolving Period.

Upon the occurrence of an Event of Default, the Revolving Period for all Classes and Series of the Notes shall automatically terminate and the Full Amortization Period for all Outstanding Notes shall commence without further action on the part of any Person, unless, together, the Majority Noteholders of all Outstanding Notes that are not Variable Funding Notes and the Majority Noteholders for each Series

(i)If at any time the Depository for a Global Note notifies the Issuer that it is unwilling or unable to continue to act as Depository for such Global Note or if at any time the Depository for the Notes for such Series or Class ceases to be a Clearing Corporation, the Issuer will appoint a successor Depository with respect to such Global Note. If a successor Depository for such Global Note is not appointed by the Issuer within ninety (90) days after the Issuer receives such notice or becomes aware of such ineligibility, the Issuer will execute, and the Indenture Trustee or its agent will, in accordance with Section 6.3 and with the Issuer Certificate

delivered to the Indenture Trustee or its agent under Section 6.3 requesting the authentication and delivery of individual Notes of such Series or Class in exchange for such Global Note, will authenticate and deliver, individual Notes of such Series or Class of like tenor and terms in an aggregate Initial Note Balance equal to the Initial Note Balance of the Global Note in exchange for such Global Note.

(ii)The Issuer may at any time and in its sole discretion determine that the Notes of any Series or Class or portion thereof issued or issuable in the form of one or more Global Notes will no longer be represented by such Global Note or Notes. In such event the Issuer will execute, and the Indenture Trustee or its agent in accordance with Section 6.3 and with the Issuer Certificate delivered to the Indenture Trustee or its agent under Section 6.3 for the authentication and delivery of individual Notes of such Series or Class in exchange in whole or in part for such Global Note, will authenticate and deliver individual Notes of such Series or Class of like tenor and terms in definitive form in an aggregate Initial Note Balance equal to the Initial Note Balance of such Global Note or Notes representing such Series or Class or portion thereof in exchange for such Global Note or Notes.

(iii)If specified by the Issuer pursuant to Sections 5.2 and 6.1 with respect to Notes issued or issuable in the form of a Global Note, the Depository for such Global Note may surrender such Global Note in exchange in whole or in part for individual Notes of such Series or Class of like tenor and terms in definitive form on such terms as are acceptable to the Issuer and such Depository. Thereupon the Issuer will execute, and the Indenture Trustee or its agent will, in accordance with Section 6.3 and with the Issuer Certificate delivered to the Indenture Trustee or its agent under Section 6.3, authenticate and deliver, without service charge, (A) to each Person specified by such Depository a new Note or Notes of the same Series or Class of like tenor and terms and of any authorized denomination as requested by such Person in an aggregate Initial Note Balance equal to the Initial Note Balance of the portion of the Global Note or Notes specified by the Depository and in exchange for such Person’s beneficial interest in the Global Note; and

(B) to such Depository a new Global Note of like tenor and terms and in an authorized denomination equal to the difference, if any, between the Initial Note Balance of the surrendered Global Note and the aggregate Initial Note Balance of Notes delivered to the Noteholders thereof.

(iv)If any Event of Default has occurred with respect to such Global Notes, and Owners of Notes evidencing more than 50% of the Global Notes of that Series or Class (measured by Voting Interests) advise the Indenture Trustee and the Depository that a Global Note is no longer in the best interest of the Note Owners, the Owners of Global Notes of that Series or Class may exchange their beneficial interests in such Notes for Definitive Notes in accordance with the exchange provisions herein.

(v)In any exchange provided for in any of the preceding four paragraphs, the Issuer will execute and the Indenture Trustee or its agent will, in accordance with Section 6.3 and with the Issuer Certificate delivered to the Indenture Trustee or its agent under Section 6.3, authenticate and deliver Definitive Notes in definitive registered form in authorized denominations. Upon the exchange of the entire Initial Note Balance of a Global Note for Definitive Notes, such Global Note will be canceled by the Indenture Trustee or its agent. Except

as provided in the preceding paragraphs, Notes issued in exchange for a Global Note pursuant to this Section will be registered in such names and in such authorized denominations as the Depository for such Global Note, pursuant to instructions from its direct or indirect participants or otherwise, will instruct the Indenture Trustee or the Note Registrar. The Indenture Trustee or the Note Registrar will deliver such Notes to the Persons in whose names such Notes are so registered.

Section 5.5. Beneficial Ownership of Global Notes.

Until Definitive Notes have been issued to the applicable Noteholders to replace any Global Notes with respect to a Series or Class pursuant to Section 5.4 or as otherwise specified in any applicable Indenture Supplement:

(a)the Issuer and the Indenture Trustee may deal with the applicable clearing agency or Depository and the Depository Participants for all purposes (including the making of payments) as the authorized representatives of the respective Note Owners; and

(b)the rights of the respective Note Owners will be exercised only through the applicable Depository and the Depository Participants and will be limited to those established by law and agreements between such Note Owners and the Depository and/or the Depository Participants. Pursuant to the operating rules of the applicable Depository, unless and until Definitive Notes are issued pursuant to Section 5.4, the Depository will make book-entry transfers among the Depository Participants and receive and transmit payments of principal and interest on the related Notes to such Depository Participants.

For purposes of any provision of this Base Indenture requiring or permitting actions with the consent of, or at the direction of, Noteholders evidencing a specified percentage of the Note Balance of Outstanding Notes, such direction or consent may be given by Note Owners (acting through the Depository and the Depository Participants) owning interests in or security entitlements to Notes evidencing the requisite percentage of principal amount of Notes.

Section 5.6. Notices to Depository.

Whenever any notice or other communication is required to be given to Noteholders with respect to which Book-Entry Notes have been issued, unless and until Definitive Notes will have been issued to the related Note Owners, the Indenture Trustee will give all such notices and communications to the applicable Depository, and shall have no obligation to report directly to such Note Owners.

Every Note presented or surrendered for transfer or exchange will (if so required by the Issuer, the Note Registrar or the Indenture Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Issuer, the Indenture Trustee, and the Note Registrar duly executed, by the Noteholder thereof or such Noteholder’s attorney duly authorized in writing, with such signature guaranteed by an “eligible guarantor institution” meeting the requirements of the Securities Transfer Agent’s Medallion Program.

(h)Conditions to Transfer. No sale, pledge or other transfer (a “Transfer”) of any Notes shall be made unless that Transfer is made pursuant to an effective registration statement under the 1933 Act and effective registration or qualification under applicable state securities laws or is made in a transaction that does not require such registration or qualification. If a Transfer is made without registration under the 1933 Act (other than in connection with the initial issuance thereof by the Issuer), then the Note Registrar, the Indenture Trustee, Administrator, on behalf of the Issuer, shall refuse to register such Transfer unless the Note Registrar receives either:

(i)the Regulation S Note Transfer Certificate or Rule 144A Note Transfer Certificate and such other information as may be required pursuant to this Section 6.5; or

In connection with any Transfer of Notes in reliance on Rule 144A, the Administrator shall furnish upon request of a Noteholder to such Noteholder and any prospective purchaser designated by such Noteholder the information required to be delivered under paragraph (d)(4) of Rule 144A.

In the event that a Note is transferred to a Person that does not meet the requirements of this Section 6.5 and/or the requirements of the related Indenture Supplement, such transfer will be of no force and effect, will be void ab initio, and will not operate to transfer any right to such Person, notwithstanding any instructions to the contrary to the Issuer, the Indenture Trustee or any intermediary; and the Indenture Trustee shall not make any payment on such Note for as long as such Person is the Noteholder of such Note and the Indenture Trustee shall have the right to compel such Person to transfer such Note to a Person who does meet the requirements of this Section 6.5.

that an applicable Note Rating Agency no longer provides such written confirmation described in the foregoing clause (1), (a) the Administrator shall provide notice of such new issuance to the related Note Rating Agency and (b) each of the parties that would be Administrative Agents after giving effect to the new issuance shall have provided their prior written consent to such new issuance which may be given in reliance in part on the Issuer’s Certificate delivered pursuant to Section 6.10(b)(ii) above;

(vi)no Event of Default shall have occurred and be continuing, as evidenced by an Issuer’s Certificate, unless (a) the proceeds of such new Notes are applied in whole or in part to redeem all other Outstanding Notes and/or (b) the Noteholders of any Notes that will remain Outstanding consent to such issuance of new Notes;

(vii)on or prior to the date that the new issuance is to occur, the Issuer will have delivered to the Indenture Trustee an Indenture Supplement and, if applicable, the Issuer Certificate;

(xi)any other conditions specified in the applicable Indenture Supplement;

provided, however, that any one of the aforementioned conditions may be eliminated (other than clause (ii) with respect to the Issuer Tax Opinion requirement, clause (v) and clause (xi) above) or modified as a condition precedent to any new issuance of a Series or Class of Notes if the Issuer has obtained approval from each Note Rating Agency that is at that time rating any Outstanding Notes that will remain Outstanding after the new issuance.

(c)No Notice or Consent Required to or from Existing Noteholders and Owners. Except as provided in Section 6.10(b) above or in any Indenture Supplement, the Issuer and the Indenture Trustee will not be required to provide prior notice to or to obtain the consent of any Noteholder or Note Owner of Notes of any Outstanding Series or Class to issue any additional Notes of any Series or Class.

(f)Increase or Reduction in Maximum VFN Principal Balance. The increase or reduction in the Maximum VFN Principal Balance in respect of any Outstanding Class of Notes, the increase or decrease of any Advance Rates in respect thereof and/or the increase or decrease of interest rates in respect thereof shall not constitute an issuance of “new Notes” for purpose of this Section 6.10.

Section 7.2. Application of Trust Money.

All money and obligations deposited with the Indenture Trustee pursuant to Section 7.1 and all money received by the Indenture Trustee in respect of such obligations will be held in trust and applied by it or the Paying Agent, in accordance with the provisions of the Class of Notes in respect of which it was deposited and this Base Indenture and the related Indenture Supplement, to the payment to the Persons entitled thereto, of the principal and interest for whose payment that money and obligations have been deposited with or received by the Indenture Trustee or the Paying Agent.

Section 7.3. Cancellation of Notes Held by the Issuer or NSM.

If the Issuer, NSM or any of their respective Affiliates holds any Notes, that Noteholder may, subject to any provision of a related Indenture Supplement limiting the repayment of such Notes by notice from that Noteholder to the Indenture Trustee, cause the Notes to be repaid and canceled, whereupon the Notes will no longer be Outstanding; provided, that, such repayment and cancelation shall be subject to the written consent of the Administrative Agent.

Section 7.4. Extinguishment of Issuer’s Rights in Collateral.

(a)The Issuer acknowledges and agrees that upon the issuance of a letter of extinguishment by Ginnie Mae pursuant to the Ginnie Mae Contract or the Acknowledgment Agreement (a “Letter of Extinguishment”) to Servicer, such Letter of Extinguishment shall, except as otherwise provided in the Acknowledgment Agreement, result in the complete extinguishment of all redemption, equitable, legal or other right, title or interest of the Servicer in the Pooled Mortgages and any servicing income (including the related MSRs) derived therefrom, therefore instantly and automatically extinguishing the security interest granted hereunder as it relates in any way to the Pooled Mortgages.

(b)As a result of the extinguishment of Servicer’s rights in all or a portion of the Collateral, Issuer acknowledges that:

(1)the Indenture Trustee, on behalf of the Secured Parties, shall have rights pursuant to the Acknowledgment Agreement with respect to the Pooled Mortgages (including, but not limited to, the ability to appoint a “standby issuer” that will assume the duties rights and obligations of the Servicer with respect to the Pooled Mortgages); and

(2)notwithstanding such rights, none of the Indenture Trustee, the Administrative Agent or the Noteholders shall have any responsibility, express or implied, to protect or consider Servicer’s rights or interests in connection with any of the Indenture Trustee’s actions or inactions pursuant to the Acknowledgment Agreement, including the receipt of any amounts with respect to the Pooled Mortgages following any transfer of Issuer responsibility.

(c)Any amounts received by the Indenture Trustee or any standby issuer appointed or otherwise designated by the Indenture Trustee in connection with the Acknowledgment Agreement shall be applied first, to satisfy any costs and expenses of the Indenture Trustee, such standby issuer or any of their affiliates in connection with any of the transactions contemplated by any of the Transaction Documents and second, to reduce the other obligations.

(d)The Servicer acknowledges that, notwithstanding the extinguishment of its rights in the Pooled Mortgages, it remains obligated in accordance with the terms hereof to the extent that any amounts payable to the Indenture Trustee, the Administrative Agent, the Noteholders or any Indemnified Party hereunder have not been paid in full.

(e)Any provision providing for the exercise of any action or discretion by the Indenture Trustee, with respect to any provision of the Acknowledgment Agreement, including Section 8 thereof, as a result of an event of default under the Ginnie Mae Contract (including, but not limited to, the appointment of a “Standby Issuer” under the Acknowledgment Agreement), shall be exercised by the Indenture Trustee at the written direction of 100% of the VFN Noteholders and to effect the cure available under the Acknowledgment Agreement, at the written direction of the holder of each MBS Advance VFN. Any provision providing for the exercise of any action or discretion by the Indenture Trustee, with respect to any provision of the Credit Management Agreement shall be exercised by the Indenture Trustee at the written direction of the Majority Noteholders.

The Indenture Trustee shall provide notice of defaults in accordance with Section 3.3(b) and Section 11.2.

Section 8.2. Acceleration of Maturity; Rescission and Annulment.

(a)If an Event of Default of the kind specified in clauses (b), (c) or (p) of Section 8.1 occurs, the unpaid principal amount of all of the Notes shall automatically become immediately due and payable without notice, presentment or demand of any kind. If any other Event of Default occurs and is continuing, then and in each and every such case, the Indenture Trustee, at the written direction of any of the Administrative Agent, the Majority Noteholders of all Outstanding Notes that are not Variable Funding Notes or the Majority Noteholders for any Series of Outstanding Variable Funding Notes, may declare the Note Balance of all the Outstanding Notes and all interest and principal accrued and unpaid (if any) thereon and all other amounts due and payable under any Transaction Document to be due and payable immediately, and upon any such declaration each Note will become and will be immediately due and payable and the Revolving Period with respect to such Series or Class shall immediately terminate, anything in this Base Indenture, the related Indenture Supplement(s) or in the Notes to the contrary notwithstanding. Such payments are subject to the allocation, deposits and payment sections of this Base Indenture and of the related Indenture Supplement(s).

(b)At any time after such a declaration of acceleration has been made or an automatic acceleration has occurred with respect to the Notes of any Series or Class and before a judgment or decree for payment of the money due has been obtained by the Indenture Trustee as hereafter provided in this Article VIII, the Majority Noteholders of all Outstanding Notes, by written notice to the Issuer and the Indenture Trustee, may rescind and annul such declaration and its consequences if:

(i)the Issuer has paid or deposited with the Indenture Trustee a sum sufficient to pay (A) all overdue installments of interest on such Notes, (B) the principal of such Notes which has become due otherwise than by such declaration of acceleration, and interest thereon at the rate or rates prescribed therefor by the terms of such Notes, to the extent that payment of such interest is lawful, (C) interest upon overdue installments of interest at the rate or rates prescribed therefore by the terms of such Notes to the extent that payment of such interest is lawful, and (D) all sums paid by the Indenture Trustee hereunder and the reasonable compensation, expenses and disbursements of the Indenture Trustee or the bank serving as Indenture Trustee (in any of its capacities), their agents and counsel, all other amounts due under Section 4.5; and

(ii)all Events of Default, other than the nonpayment of the principal of such Notes which has become due solely by such acceleration, have been cured or waived as provided in Section 8.14.

No such rescission will affect any subsequent default or impair any right consequent thereon.

Section 8.3. Collection of Indebtedness and Suits for Enforcement by Indenture Trustee.

The Issuer covenants that if:

(a)the Issuer defaults in the payment of interest on any Notes when such interest becomes due and payable, which default continues for a period of two (2) Business Days following written notice from the Indenture Trustee of such default; or

(b)the Issuer defaults in the payment of the principal of any Series or Class of Notes on the Stated Maturity Date thereof; then:

the Issuer will, upon demand of the Indenture Trustee, pay (subject to the allocation provided in Section 4.5(a)(2) hereof and any related Indenture Supplement) to the Indenture Trustee, for the benefit of the Noteholders of any such Notes, the whole amount then due and payable on any such Notes for principal and interest, together with any Cumulative Interest Shortfall Amounts, unless otherwise specified in the applicable Indenture Supplement, and in addition thereto, will pay such further amount as will be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and the bank serving as Indenture Trustee (in any of its capacities), their agents and counsel and all other amounts due under Section 4.5.

If the Issuer fails to pay such amounts forthwith upon such demand, the Indenture Trustee may, in its own name and as trustee of an express trust, institute a judicial proceeding for the collection of the sums so due and unpaid, and may directly prosecute such proceeding to judgment or final decree, and the Indenture Trustee may enforce the same against the Issuer or any other obligor upon the Notes and collect the money adjudged or decreed to be payable in the manner provided by law and this Base Indenture.

Section 8.4. Indenture Trustee May File Proofs of Claim.

In case of the pendency of any Insolvency Event or other similar proceeding or event relative to the Issuer or any other obligor upon the Notes or the property of the Issuer or of such other obligor, the Indenture Trustee (irrespective of whether the principal of the Notes will then be due and payable as therein expressed or by declaration or otherwise) will be entitled and empowered by intervention in such proceeding or otherwise:

(a)to file and prove a claim for the whole amount of principal and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary and advisable in order to have the claims of the Indenture Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee, its agents and counsel and all other amounts due under Section 4.5) and of the Noteholders allowed in such judicial proceeding; and

(b)to collect and receive any funds or other property payable or deliverable on any such claims and to distribute the same; and any receiver, assignee, trustee, liquidator or other similar official in any such proceeding is hereby authorized by each Noteholder to make such payment to the Indenture Trustee and the bank serving as Indenture Trustee (in all its capacities), and in the event that the Indenture Trustee consents to the making of such payments directly to the Noteholders, to pay to the Indenture Trustee and the bank serving as Indenture Trustee (in all its capacities) any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and the bank serving as Indenture Trustee (in all its capacities), their agents and counsel, and any other amounts due the Indenture Trustee and the bank serving as Indenture Trustee (in all its capacities) under Section 4.5.

Nothing herein contained will be deemed to authorize the Indenture Trustee to authorize or consent to or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Noteholder thereof, or to authorize the Indenture Trustee to vote in respect of the claim of any Noteholder in any such proceeding.

Section 8.5. Indenture Trustee May Enforce Claims Without Possession of Notes.

All rights of action and claims under this Base Indenture or the Notes of any Series or Class are subject to Ginnie Mae Requirements and may be prosecuted and enforced by the Indenture Trustee, without the possession of any of the Notes of such Series or Class or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Indenture Trustee, will be brought in its own name as trustee of an express trust, and any recovery of judgment will, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Indenture Trustee and its respective agents and counsel, be for the ratable benefit of the Noteholders of the Notes of such Series or Class in respect of which such judgment has been recovered.

Section 8.6. Application of Money Collected.

Any money or other property collected by the Indenture Trustee pursuant to this Article VIII will be applied in accordance with Section 4.5(a)(2), at the Final Payment Date fixed by the Indenture Trustee and, in case of the payment of such money on account of principal, interest or fees, upon presentation of the Notes of the related Series or Class and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid.

Section 8.7. Sale of Collateral Requires Consent of Noteholders.

Subject to Ginnie Mae Requirements, the Indenture Trustee shall not sell Collateral or cause the Issuer to sell Collateral following any Event of Default, except with the written consent, or at the direction of, the Majority Noteholders of each Series; provided, that the Indenture Trustee shall, subject to the consent of Ginnie Mae, and pursuant to the terms of the Credit Management Agreement, sell Collateral or cause the Issuer to sell Collateral without prior consent of any of the Noteholders if an Event of Default under clauses (b), (c) or (p) of Section 8.1 occurs. Notwithstanding the foregoing, the consent of 100% of the Noteholders of the Outstanding Notes of each Series shall be required for any sale that does not generate sufficient proceeds to pay the Note Balance of all such Notes plus all accrued and unpaid interest and other amounts owed in respect of such Notes and the Transaction Documents. If such direction has been given by the Noteholders of the requisite percentage of all Outstanding Notes, the Indenture Trustee shall, subject to Ginnie Mae Requirements and the terms of the Acknowledgment Agreement, cause the Issuer to sell Collateral pursuant to Section 8.15, and shall provide notice of this to each Note Rating Agency of then Outstanding Notes.

Section 8.8. Limitation on Suits.

No Noteholder will have any right to institute any proceeding, judicial or otherwise, with respect to this Base Indenture or any Note, or for the appointment of a receiver or trustee or similar official, or for any other remedy hereunder, unless:

(a)such Noteholder has previously given written notice to the Indenture Trustee of a continuing Event of Default with respect to Notes of such Noteholder’s Notes, Series or Class;

(b)the Noteholders of more than 50% of the Note Balance of the Outstanding Notes of each Series, measured by Voting Interests, have made written request to the Indenture Trustee to institute proceedings in respect of such Event of Default in the name of the Indenture Trustee hereunder;

(c)such Noteholder or Noteholders have offered to the Indenture Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; and

(d)the Indenture Trustee, for sixty (60) days after the Indenture Trustee has received such notice, request and offer of indemnity, has failed to institute any such proceeding; it being understood and intended that no one or more Noteholders of Notes of such Series or Class will have any right in any manner whatsoever by virtue of, or by availing of, any provision of this Base Indenture or any Note to affect, disturb or prejudice the rights of any other Noteholders of Notes, or to obtain or to seek to obtain priority or preference over any other such Noteholders or to enforce any right under this Base Indenture or any Note, except in the manner herein provided and for the equal and proportionate benefit of all the Noteholders of all Notes.

Section 8.9. Limited Recourse.

Notwithstanding any other terms of this Base Indenture, the Notes, any other Transaction Documents or otherwise, the obligations of the Issuer under the Notes, this Base Indenture and each other Transaction Document to which it is a party are limited recourse obligations of the Issuer, payable solely from the Trust Estate, and following realization of the Trust Estate and application of the proceeds thereof in accordance with the terms of this Base Indenture, none of the Noteholders, the Indenture Trustee or any of the other parties to the Transaction Documents shall be entitled to take any further steps to recover any sums due but still unpaid hereunder or thereunder, all claims in respect of which shall be extinguished and shall not thereafter revive. Subject to the foregoing and to the terms of the applicable Indenture Supplement, each Noteholder will, however, have the absolute and unconditional right to receive payment of all amounts due with respect to the Notes pursuant and respect to the terms of the Indenture, which right shall not be impaired without the consent of each Noteholder and to initiate suit for the enforcement of any such payment, which right shall not be impaired without the consent of such Noteholder. No recourse shall be had for the payment of any amount owing in respect of the Notes or this Base Indenture or for any action or inaction of the Issuer against any officer, director, employee, equity holder or organizer of the Issuer or any of their successors or assigns for any amounts payable under the Notes or this Base Indenture. It is understood that the foregoing provisions of this Section 8.9 shall not (i) prevent recourse to the Trust Estate for the sums due or to become due under any security, instrument or agreement which is part of the Trust Estate, (ii) prevent recourse to NSM under the PC Repurchase Agreement or (iii) save as specifically provided therein, constitute a waiver, release or discharge of any indebtedness or obligation evidenced by the Notes or secured by this Base Indenture. It is further understood that the foregoing provisions of this Section 8.9 shall not limit the right of any Person, to name the Issuer as a party defendant in any proceeding or in the exercise of any other remedy under the Notes or this Base Indenture, so long as no judgment in the nature of a deficiency judgment or seeking personal liability shall be asked for or (if obtained) enforced against any such Person or entity.

Section 8.10. Restoration of Rights and Remedies.

If the Indenture Trustee or any Noteholder has instituted any proceeding to enforce any right or remedy under this Base Indenture and such proceeding has been discontinued or abandoned for any reason, then and in every such case the Issuer, the Indenture Trustee and the Noteholders will, subject to any determination in such proceeding, be restored severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Indenture Trustee and the Noteholders will continue as though no such proceeding had been instituted.

Section 8.11. Rights and Remedies Cumulative.

No right or remedy herein conferred upon or reserved to the Indenture Trustee or to the Noteholders is intended to be exclusive of any other right or remedy, and every right and remedy will, to the extent permitted by law, be cumulative and in addition to every other right and remedy given

hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, will not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 8.12. Delay or Omission Not Waiver.

No delay or omission of the Indenture Trustee or of any Noteholder to exercise any right or remedy accruing upon any Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or acquiescence therein. Every right and remedy given by this Article or by law to the Indenture Trustee or to the Noteholders may be exercised from time to time, and as often as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as the case may be.

Section 8.13. Control by Noteholders.

Either 100% of the VFN Noteholders or the Majority Noteholders of all Outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Indenture Trustee, or exercising any trust or power conferred on the Indenture Trustee with respect to such Notes; provided that:

(a)the Indenture Trustee will have the right to decline to follow any such direction if the Indenture Trustee, being advised by counsel, determines that the action so directed may violate applicable law or would conflict with this Base Indenture or if the Indenture Trustee in good faith determines that the proceedings so directed would have a substantial likelihood of involving it in personal liability or be unjustly prejudicial to the Noteholders not taking part in such direction, unless the Indenture Trustee has received indemnity satisfactory to it from the Noteholders;

(b)the Indenture Trustee may take any other action permitted hereunder deemed proper by the Indenture Trustee which is not inconsistent with such direction; and

(c)to the extent there are conflicting directions between 100% of the VFN Noteholders and the Majority Noteholders, the Indenture Trustee will take its direction from 100% of the VFN Noteholders.

Section 8.14. Waiver of Past Defaults.

Together, the Majority Noteholders of all Outstanding Notes that are not Variable Funding Notes, the Majority Noteholders for each Series of Variable Funding Notes Outstanding and the Administrative Agent may, on behalf of the Noteholders of all such Notes, waive any past default hereunder and its consequences, except a default not theretofore cured:

(a)in the payment of the principal of or interest on any Note, or

(b)in respect of a covenant or provision hereof which under Article XII cannot be modified or amended without the consent of the Noteholder of each Outstanding Note.

Upon any such waiver, such default will cease to exist, and any Event of Default arising therefrom will be deemed to have been cured, for every purpose of this Base Indenture; but no such waiver will extend to any subsequent or other default or impair any right consequent thereon.

Section 8.15. Sale of Trust Estate.

(a)The power to effect any Sale of any portion of the Trust Estate shall not be exhausted by any one or more Sales as to any portion of the Trust Estate remaining unsold, but shall continue unimpaired until the entire Trust Estate shall have been sold or all amounts payable on the Notes and under this Base Indenture with respect thereto shall have been paid. The Indenture Trustee may from time to time postpone any public Sale by public announcement made at the time and place of such Sale.

(b)Unless the Majority Noteholders of all Series of Outstanding Notes (or 100% of the VFN Noteholders) have otherwise provided its written consent to the Indenture Trustee, at any public Sale of all or any portion of the Trust Estate at which a minimum bid equal to or greater than all amounts due to the Indenture Trustee hereunder and the entire amount which would be payable to the Noteholders in full payment thereof in accordance with Section 8.6, on the Payment Date next succeeding the date of such sale, has not been received, the Indenture Trustee shall prevent such sale by bidding an amount at least $1.00 more than the highest other bid in order to preserve the Trust Estate.

(c)In connection with a Sale of all or any portion of the Trust Estate:

(i)any of the Noteholders may bid for and purchase the property offered for Sale, and upon compliance with the terms of sale may hold, retain and possess and dispose of such property, without further accountability;

(ii)the Indenture Trustee may bid for and acquire the property offered for Sale in connection with any Sale thereof;

(iii)the Indenture Trustee shall execute and deliver an appropriate instrument of conveyance transferring its interest in any portion of the Trust Estate in connection with a Sale thereof;

(iv)the Indenture Trustee is hereby irrevocably appointed the agent and attorney-in-fact of the Issuer to transfer and convey its interest in any portion of the Trust Estate in connection with a Sale thereof, and to take all action necessary to effect such Sale; and

(v)no purchaser or transferee at such a Sale shall be bound to ascertain the Indenture Trustee’s authority, inquire into the satisfaction of any conditions precedent or see to the application of any moneys.

(d)Notwithstanding anything to the contrary in this Base Indenture, and subject to Ginnie Mae Requirements, if an Event of Default has occurred and is continuing and the Notes have become due and payable or have been declared due and payable and such declaration and its consequences have not been rescinded and annulled, any proceeds received by the Indenture Trustee with respect to a foreclosure, sale or other realization resulting from a transfer of the assets of the Trust Estate shall be allocated in accordance with Section 4.5(a)(2) hereof. The amount, if any, so allocated to the Issuer shall be paid by the Indenture Trustee to or to the order of the Issuer free and clear of the Adverse Claim of this Base Indenture and the Noteholders shall have no claim or rights to the amount so allocated.

Section 8.16. Undertaking for Costs.

All parties to this Base Indenture agree, and each Noteholder by its acceptance thereof will be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Base Indenture, or in any suit against the Indenture Trustee for any action taken

or omitted by it as Indenture Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section will not apply to any suit instituted by the Indenture Trustee, to any suit instituted by any Noteholder or group of Noteholders holding in the aggregate more than 25% of the Note Balance of the Outstanding Notes of each Series (measured by Voting Interests) to which the suit relates, or to any suit instituted by any Noteholders for the enforcement of the payment of the principal of or interest on any Note on or after the applicable Stated Maturity Date expressed in such Note.

Section 8.17. Waiver of Stay or Extension Laws.

The Issuer covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Base Indenture; and the Issuer (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Indenture Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 8.18. Notice of Waivers.

Promptly (and in no event later than two (2) Business Days following the occurrence thereof), after any waiver of an Event of Default pursuant to Section 4.12, or any rescission or annulment of a declaration of acceleration pursuant to Section 8.2(b), or any waiver of past default pursuant to Section 8.14, the Issuer will notify all related Note Rating Agencies, Ginnie Mae and the Credit Manager in writing.

Article IX
The Issuer

Section 9.1. Representations and Warranties of Issuer.

The Issuer hereby makes the following representations and warranties for the benefit of the Servicer, the Indenture Trustee, the Credit Manager and the Noteholders. The representations shall be made as of the execution and delivery of this Base Indenture and of each Indenture Supplement, and as of each Funding Date and as of each date of Grant and shall survive the Grant of a Security Interest in the Participation Certificates to the Indenture Trustee.

(a)Organization and Good Standing. The Issuer is duly organized and validly existing as a statutory trust and is in good standing under the laws of the State of Delaware, with power and authority to own its properties and to conduct its business as such properties are currently owned and such business is presently conducted. The Issuer has appointed the Administrator as the Issuer’s agent where notices and demands to or upon the Issuer in respect of the Notes of this Base Indenture may be served.

(b)Power and Authority. The Issuer has and will continue to have the power and authority to execute and deliver this Base Indenture and the other Transaction Documents to which it is or will be a party, and to carry out their respective terms; the Issuer had and has had at all relevant times and now has full power, authority and legal right to acquire, own, hold and Grant a Security Interest in the Trust Estate and has duly authorized such Grant to the Indenture Trustee by all necessary action; and the execution,

delivery and performance by the Issuer of this Base Indenture and each of the other Transaction Documents to which it is a party has been duly authorized by all necessary action of the Issuer.

(c)Valid Transfers; Binding Obligations. This Base Indenture creates a valid Grant of a Security Interest in the Participation Certificates which has been validly perfected and is a first priority Security Interest under the UCC, and such other portion of the Collateral as to which a Security Interest may be granted under the UCC, which security interest is enforceable against creditors of and purchasers from the Issuer, subject to applicable law. Each of the Transaction Documents to which the Issuer is a party constitutes a legal, valid and binding obligation of the Issuer enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization or other similar laws affecting creditors’ rights generally or by general equity principles.

(d)No Violation. The execution and delivery by the Issuer of this Base Indenture and each other Transaction Document to which it is a party and the consummation of the transactions contemplated by this Base Indenture and the other Transaction Documents and the fulfillment of the terms of this Base Indenture and the other Transaction Documents do not conflict with, result in any breach of any of the terms or provisions of, or constitute (with or without notice or lapse of time or both) a default under the Organizational Documents of the Issuer or any indenture, agreement or other material instrument to which the Issuer is a party or by which it is bound, or result in the creation or imposition of any Adverse Claim upon any of its properties pursuant to the terms of any such indenture, agreement or other instrument (other than this Base Indenture), or violate any law, order, judgment, decree, writ, injunction, award, determination, rule or regulation applicable to the Issuer of any court or of any federal or state regulatory body, administrative agency or other governmental instrumentality having jurisdiction over the Issuer or its properties, which breach, default, conflict, Adverse Claim or violation could reasonably be expected to have a material Adverse Effect or a material adverse effect on the business, financial condition or results of operations of the Issuer.

(e)No Proceedings. There is no action, suit or proceeding before or by any court or governmental agency or body, domestic or foreign, now pending, or to the Issuer’s knowledge, threatened, against or affecting the Issuer: (i) asserting the invalidity of this Base Indenture, the Notes or any of the other Transaction Documents to which the Issuer is a party, (ii) seeking to prevent the issuance of the Notes or the consummation of any of the transactions contemplated by this Base Indenture, or any of the other Transaction Documents, (iii) seeking any determination or ruling which could reasonably be expected to have a material Adverse Effect or could reasonably be expected to materially and adversely affect the condition (financial or otherwise), business or operations of the Issuer, or (iv) relating to the Issuer and which could reasonably be expected to adversely affect the United States federal income tax attributes of the Notes.

(f)No Subsidiaries. The Issuer has no subsidiaries.

(g)All Tax Returns True, Correct and Timely Filed. All tax returns required to be filed by the Issuer in any jurisdiction have in fact been filed and all taxes, assessments, fees and other governmental charges upon the Issuer or upon any of its properties, and all income of franchises, shown to be due and payable on such returns have been paid except for any such taxes, assessments, fees and charges the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Issuer had established adequate reserves in accordance with GAAP. All such tax returns were true and correct in all material respects and the Issuer

knows of no proposed additional tax assessment against it that could reasonably be expected to have a material adverse effect upon the ability of the Issuer to perform its obligations hereunder nor of any basis therefor. The provisions for taxes on the books of the Issuer are in accordance with GAAP.

(h)No Restriction on Issuer Affecting its Business. The Issuer is not a party to any contract or agreement, or subject to any charter or other restriction, which materially and adversely affects its business, and the Issuer has not agreed or consented to cause any of its assets or properties to become subject to any Adverse Claim other than the Security Interest or any Permitted Liens.

(i)Title to Participation Certificates. As represented by NSM in the PC Repurchase Agreement, immediately prior to the Grant thereof to the Indenture Trustee as contemplated by this Base Indenture, subject to Ginnie Mae Requirements with respect thereto, the Issuer had good and marketable title to each Participation Certificate, free and clear of all Adverse Claims other than any Permitted Liens and rights of others.

All filings and recordings against the Issuer required to perfect the Security Interest of the Indenture Trustee in such Participation Certificates and such other portion of the Trust Estate as to which a Security Interest may be perfected by filing under the UCC, have been accomplished and are in full force and effect, and all such filings and recordings against the Issuer include the legends set forth as clauses (i) through (iii) of the fourth full paragraph of the Granting Clause. Subject to the rights of Ginnie Mae with respect thereto, other than the Security Interest granted to the Indenture Trustee pursuant to this Base Indenture, the Issuer has not pledged, assigned, sold, granted a Security Interest in, or otherwise conveyed any of the Participation Certificates or any other Collateral. The Issuer has not authorized the filing of and is not aware of any financing statement filed against the Issuer that includes a description of collateral covering the Participation Certificates other than (1) any financing statement related to the Security Interest granted to the Indenture Trustee hereunder or (2) that has been terminated.

(k)Notes Authorized, Executed, Authenticated, Validly Issued and Outstanding. The Notes have been duly and validly authorized and, when duly and validly executed and authenticated by the Indenture Trustee in accordance with the terms of this Base Indenture and delivered to and paid for by each purchaser as provided herein, will be validly issued and outstanding and entitled to the benefits hereof.

Noteholders of all Outstanding Notes to further perfect or evidence the rights, claims or security interests of the Indenture Trustee and the Noteholders under any of the Transaction Documents.

The Issuer is not Granting the Trust Estate to the Indenture Trustee with the intent to defraud, delay or hinder any of its creditors.

(n)Separate Identity. The Issuer is operated as an entity separate from the Servicer and the Administrator. The Issuer has complied with all covenants set forth in its Organizational Documents except where the failure to do so could reasonably be expected to have an Adverse Effect.

(s)Investment Company. The Issuer is not required to be registered as an “investment company” within the meaning of the Investment Company Act, or any successor statute.

(t)Compliance with Law. The Issuer has complied in all material respects with all applicable laws, rules, regulations, orders, writs, judgments, injunctions, decrees or awards to which it may be subject except where the failure to do so could reasonably be expected to have an Adverse Effect or a material adverse effect on the business, financial condition or results of operations of the Issuer.

(u)Investments. The Issuer does not own or hold, directly or indirectly (i) any capital stock or equity security of, or any equity interest in, any Person or (ii) any debt security or other evidence of indebtedness of any Person.

(w)Limited Business. Since its formation, the Issuer has conducted no business other than entering into and performing its obligations under the Transaction Documents to which it is a party, and such other activities as are incidental to the foregoing.

Section 9.2. Liability of Issuer; Indemnities.

(a)Obligations. The Issuer shall be liable in accordance with this Base Indenture only to the extent of the obligations in this Base Indenture specifically undertaken by the Issuer in such capacity under this Base Indenture and shall have no other obligations or liabilities hereunder. The Issuer shall indemnify, defend and hold harmless the Indenture Trustee (in all its capacities), the Calculation Agent, the Paying Agent, the Securities Intermediary, the Note Registrar, the Credit Manager, the Administrative Agent, the Noteholders and their respective directors, officers, agents and employees (as applicable, with respect to the related Series of Notes) and the Trust Estate (each an “Issuer Indemnified Party”) from and against (i) any and all losses, claims, damages, liabilities, deficiencies, judgments or expenses incurred by any of them which may be imposed on, incurred by or asserted against such Issuer Indemnified Party in exercising its powers, rights and remedies or performing its duties hereunder or under the other Transaction Documents or otherwise in its capacity as an Issuer Indemnified Party in any way relating to or arising out of this Base Indenture or the other Transaction Documents, including amounts paid in settlement, court costs and reasonable fees and disbursements of counsel incurred in connection with any such litigation, investigation, claim or proceeding or any advice rendered in connection with any of the foregoing. and (ii) any taxes that may at any time be asserted against the Indenture Trustee, the Calculation Agent, the Paying Agent, the Securities Intermediary, the Note Registrar, the Credit Manager, the Administrative Agent, the Noteholders (as applicable, with respect to the related Series of Notes) or the Trust Estate with respect to the transactions contemplated in this Base Indenture or any of the other Transaction Documents, including any sales, gross receipts, general corporation, tangible or intangible personal property, privilege or license taxes (but not including any taxes asserted with respect to, and as of the date of, the transfer of the Participation Certificates to the Trust Estate, the issuance and original sale of the Notes of any Class, or asserted with respect to ownership of the Participation Certificates, or federal, state or local income or franchise taxes or any other tax, or other income taxes arising out of payments on the Notes of any Class, or any interest or penalties with respect thereto or arising from a failure to comply therewith) and, in each case, any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Issuer, and regardless of whether any Issuer Indemnified Party is a party thereto and costs and expenses in defending against the same and in connection with the Issuer Indemnified Parties’ enforcement of any rights hereunder or under any Transaction Document, except that in no event shall the Issuer be required to indemnify any Issuer Indemnified Party if the indemnification obligation under this Section 9.2(a) to such Issuer Indemnified Party is the result of gross negligence or willful misconduct by such Issuer Indemnified Party.

(b)Notification and Defense. Promptly after any Issuer Indemnified Party shall have been served with the summons or other first legal process or shall have received written notice of the threat of a claim in respect of which a claim for indemnity may be made against the Issuer under this Section 9.2, the Issuer Indemnified Party shall notify the Issuer and the Administrator in writing of the service of such summons, other legal process or written notice, giving information therein as to the nature and basis of the claim, but failure so to notify the Issuer shall not relieve the Issuer from any liability which it may have hereunder or otherwise, except to the extent that the Issuer is prejudiced by such failure so to notify the Issuer. The Issuer will be entitled, at its own expense, to participate in the defense of any such claim or action and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such Issuer Indemnified Party, and, after notice from the Issuer to such Issuer Indemnified Party that the Issuer wishes to assume the defense of any such action, the Issuer will not be liable to such Issuer Indemnified Party under this Section 9.2 for any legal or other expenses subsequently incurred by such Issuer Indemnified Party in connection with the defense of any such action unless (i) the defendants in any such action include both the Issuer Indemnified Party and the Issuer, and the Issuer Indemnified Party (upon the advice of counsel) shall have reasonably concluded that there may be legal defenses available to it that are different from or additional to those available to the Issuer, or one or more Issuer Indemnified Parties, and which in the reasonable judgment of such counsel are sufficient to create a conflict of interest for the same counsel to represent both the Issuer and such Issuer Indemnified Party, (ii) the Issuer shall not have employed counsel reasonably satisfactory to the Issuer Indemnified Party to represent the Issuer Indemnified Party within a reasonable time after notice of commencement of the action, or (iii) the Issuer has authorized the employment of counsel for the Issuer Indemnified Party at the expense of the Issuer; then, in any such event, such Issuer Indemnified Party shall have the right to employ its own counsel in such action, and the reasonable fees and expenses of such counsel shall be borne by the Issuer; provided, however, that the Issuer shall not in connection with any such action or separate but substantially similar or related actions arising out of the same general allegations or circumstances, be liable for any fees and expenses of more than one firm of attorneys at any time for all Issuer Indemnified Parties. Each Issuer Indemnified Party, as a condition of the indemnity agreement contained herein, shall use its commercially reasonable efforts to cooperate with the Issuer in the defense of any such action or claim. The Issuer shall not, without the prior written consent of any Issuer Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which such Issuer Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Issuer Indemnified Party, unless such settlement includes an unconditional release of such Issuer Indemnified Party from all liability on claims that are the subject matter of such proceeding or threatened proceeding.

(c)Expenses. Indemnification under this Section shall include reasonable and customary out-of-pocket fees and expenses of counsel and expenses of litigation. If the Issuer has made any indemnity payments pursuant to this Section and the recipient thereafter collects any of such amounts from others, the recipient shall promptly repay such amounts collected to the Issuer, without interest.

(d)Survival. The provisions of this Section 9.2 shall survive the termination of this Base Indenture.

Section 9.3. Merger or Consolidation, or Assumption of the Obligations, of the Issuer.

Any Person (a) into which the Issuer may be merged or consolidated, (b) which may result from any merger, conversion or consolidation to which the Issuer shall be a party, or (c) which may succeed to

all or substantially all of the business or assets of the Issuer, which Person in any of the foregoing cases executes an agreement of assumption to perform every obligation of the Issuer under this Base Indenture, shall be the successor to the Issuer under this Base Indenture without the execution or filing of any document or any further act on the part of any of the parties to this Base Indenture, except that if the Issuer in any of the foregoing cases is not the surviving entity, then the surviving entity shall execute an agreement of assumption to perform every obligation of the Issuer under the Transaction Documents, and the surviving entity shall have taken all actions necessary or reasonably requested by the Issuer, the Majority Noteholders of all Outstanding Notes, the Administrative Agent or the Indenture Trustee to amend its existing financing statements and continuation statements, and file additional financing statements and to take any other steps reasonably requested by the Issuer, the Majority Noteholders of all Outstanding Notes, the Administrative Agent or the Indenture Trustee to further perfect or evidence the rights, claims or security interests of the Issuer, the Noteholders or the Indenture Trustee under any of the Transaction Documents. The Issuer (i) shall provide notice of any merger, consolidation or succession pursuant to this Section 9.3 to each Note Rating Agency that has rated any then-Outstanding Notes, the Indenture Trustee, the Administrative Agent and the Noteholders, (ii) for so long as the Notes are Outstanding, (1) shall receive from each Note Rating Agency rating Outstanding Notes a letter to the effect that such merger, consolidation or succession will not result in a qualification, downgrading or withdrawal of the then current ratings assigned by such Note Rating Agency to any Outstanding Notes or (2) if the Administrator and the Administrative Agents determine in their reasonable judgment that an applicable Note Rating Agency no longer provides such letters as described in the foregoing clause (1), (a) the Administrator shall provide notice of such new merger, consolidation or succession to the related Note Rating Agency and (b) each Administrative Agent shall have provided its prior written consent to such merger, consolidation or succession; provided, that the Issuer provides an Issuer Certificate to the effect that any such merger, consolidation or succession will not have a material Adverse Effect on the Outstanding Notes, (iii) shall obtain an Opinion of Counsel addressed to the Indenture Trustee and reasonably satisfactory to the Indenture Trustee, that such merger, consolidation or succession complies with the terms hereof and one or more Opinions of Counsel updating or restating all opinions delivered on the date of this Base Indenture with respect to corporate matters, enforceability of Transaction Documents against the Issuer, and the grant by the Issuer of a valid security interest in the Participation Certificates to the Indenture Trustee and the perfection of such security interest and related matters, (iv) shall receive from the Majority Noteholders of all Outstanding Notes their prior written consent to such merger, consolidation or succession, absent which consent, which may not be unreasonably withheld or delayed, the Issuer shall not become a party to such merger, consolidation or succession and (v) shall obtain an Issuer Tax Opinion.

Section 9.4. Issuer May Not Own Notes.

The Issuer may not become the owner or pledgee of one or more of the Notes (other than any Retained Note). Any Person Controlling, Controlled by or under common Control with the Issuer may, in its individual or any other capacity, become the owner or pledgee of one or more Notes with the same rights as it would have if it were not an Affiliate of the Issuer, except as otherwise specifically provided in the definition of the term “Noteholder.” The Notes so owned by or pledged to such Controlling, Controlled or commonly Controlled Person shall have an equal and proportionate benefit under the provisions of this Base Indenture, without preference, priority or distinction as among any of the Notes, except as set forth herein with respect to, among other things, rights to vote, consent or give directions to the Indenture Trustee as a Noteholder.

Section 9.5. Covenants of Issuer.

(b)Preservation of Existence. The Issuer hereby covenants to do or cause to be done all things necessary on its part to preserve and keep in full force and effect its rights and franchises as a statutory trust under the laws of the State of Delaware, and to maintain each of its licenses, approvals, permits, registrations or qualifications in all jurisdictions in which its ownership or lease of property or the conduct of its business requires such licenses, approvals, registrations or qualifications, except for failures to maintain any such licenses, approvals, registrations or qualifications which, individually or in the aggregate, would not have a material Adverse Effect.

(c)Compliance with Laws. The Issuer hereby covenants to comply in all material respects with all applicable laws, rules and regulations and orders of any governmental authority, the noncompliance with which would have a material Adverse Effect or a material adverse effect on the business, financial condition or results of operations of the Issuer.

(d)Payment of Taxes.

(e)Investments. The Issuer hereby covenants that it will not, without the prior written consent of the Administrative Agent and Majority Noteholders of all Outstanding Notes, acquire or hold any indebtedness for borrowed money of another person, or any capital stock, debentures, partnership interests or other ownership interests or other securities of any Person, other than Permitted Investments as provided hereunder and the Participation Certificates acquired under the PC Repurchase Agreement.

(f)Keeping Records and Books of Account. The Issuer hereby covenants and agrees to maintain and implement administrative and operating procedures (including an ability to recreate records evidencing the Participation Certificates in the event of the destruction or loss of the originals thereof) and keep and maintain, all documents, books, records and other information reasonably necessary or advisable for the collection of all Participation Certificates (including records adequate to permit the daily identification of all collections with respect to, and adjustments of amounts payable under, each Participation Certificate). The Administrator shall ensure compliance with this Section 9.5(f).

(g)Employee Benefit Plans. The Issuer hereby covenants and agrees to comply in all material respects with the provisions of ERISA, the Code, and all other applicable laws, and the regulations and interpretations thereunder to the extent applicable, with respect to each Employee Benefit Plan.

The Issuer shall not take any action and shall use its best efforts not to permit any action to be taken by others that would release any Person from any of such Person’s covenants or obligations under any Transaction Document, Ginnie Mae Contract or other document, instrument or agreement included in the Trust Estate, or which would result in the amendment, hypothecation, subordination, termination or discharge of, or impair the validity or effectiveness of, any such document, instrument or agreement.

The Indemnifying Party will be entitled, at its own expense, to participate in the defense of any such claim or action and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and, after notice from the Indemnifying Party to such Indemnified Party that the Indemnifying Party wishes to assume the defense of any such action, the Indemnifying Party will not be liable to such Indemnified Party under this Section 10.4 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense of any such action unless (i) the defendants in any such action include both the Indemnified Party and the Indemnifying Party, and the Indemnified Party (upon the advice of counsel) shall have reasonably concluded that there may be legal defenses available to it that are different from or additional to those available to the Indemnifying Party, or one or more Indemnified Parties, and which in the reasonable judgment of such counsel are sufficient to create a conflict of interest for the same counsel to represent both the Indemnifying Party and such Indemnified Party, (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after notice of commencement of the action, or (iii) the Indemnifying Party has authorized the employment of counsel for the Indemnified Party at the expense of the Indemnifying Party; then, in any such event, such Indemnified Party shall have the right to employ its own counsel in such action, and the reasonable fees and expenses of such counsel shall be borne by the Indemnifying Party; provided, however, that the Indemnifying Party shall not in connection with any such action or separate but substantially similar or related actions arising out of the same general allegations or circumstances, be liable for any fees and expenses of more than one firm of attorneys at any time for all Indemnified Parties. Each Indemnified Party, as a condition of the indemnity agreement contained herein, shall use its commercially reasonable efforts to cooperate with the Indemnifying Party in the defense of any such action or claim. The Indemnifying Party shall not, without the prior written consent of any Indemnified Party, effect any settlement of any pending or threatened proceeding in respect of which such Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such proceeding or threatened proceeding.

(c)Expenses. Indemnification under this Section 9.2 shall include, without limitation, reasonable fees and expenses of counsel and expenses of litigation (including such fees and expenses incurred in enforcing the Indemnifying Party’s right to indemnification). If the Indemnifying Party has made any indemnity payments pursuant to this Section and the recipient thereafter collects any of such

amounts from others, the recipient shall promptly repay such amounts collected to the Indemnifying Party, without interest.

(d)Survival. The provisions of this Section 10.4 shall survive the resignation or removal of the Indenture Trustee, the Calculation Agent and the Paying Agent and the termination of this Base Indenture.

Section 10.5. Merger or Consolidation, or Assumption of the Obligations, of NSM.

Any Person (a) into which NSM may be merged or consolidated, (b) which may result from any merger, conversion or consolidation to which NSM shall be a party, or (c) which may succeed to all or substantially all of the business or assets of NSM which Person in any of the foregoing cases executes an agreement of assumption to perform every obligation of NSM under this Base Indenture, shall be the successor to NSM under this Base Indenture without the execution or filing of any paper or any further act on the part of any of the parties to this Base Indenture; provided, however, that (i) prior to any such merger, consolidation or conversion (1) NSM shall have provided to the Indenture Trustee, the Administrative Agent and the Noteholders a letter from each Note Rating Agency that rated Outstanding Notes indicating that such merger, consolidation or conversion will not result in the qualification, reduction or withdrawal of the then current ratings of the Outstanding Notes or (2) if the Administrator and the Administrative Agents determine in their reasonable judgment that an applicable Note Rating Agency no longer provides such letters as described in the foregoing clause (1), (a) the Administrator shall provide notice of such merger, consolidation or conversion to the related Note Rating Agency and (b) each Administrative Agent shall have provided its prior written consent to merger, consolidation or conversion; provided, that the Issuer provides an Issuer Certificate to the effect that any such merger, consolidation or conversion will not have an Adverse Effect on the Outstanding Notes, and (ii) prior to any such merger, consolidation or conversion the Administrator shall have delivered to the Indenture Trustee an Opinion of Counsel to the effect that such merger, consolidation or conversion complies with the terms of this Base Indenture and one or more Opinions of Counsel updating or restating all opinions delivered on the date of this Base Indenture with respect to corporate matters and the enforceability of Transaction Documents against NSM “safe harbor” treatment as to the transfers of the Participation Certificates from the Servicer to the Issuer and non-consolidation of the Servicer with the Issuer and security interest and tax and any additional opinions required under any related Indenture Supplement; provided, further, that the conditions specified in clauses (i) and (ii) above shall not apply to any transaction (i) in which an Affiliate of NSM assumes the obligations of NSM and otherwise satisfies the eligibility criteria applicable to the Servicer under the Ginnie Mae Contracts or (ii) in which an Affiliate of NSM is merged into or is otherwise combined with NSM and NSM is the sole survivor of such merger or other combination. NSM shall provide notice of any merger, consolidation or succession pursuant to this Section to the Indenture Trustee, the Noteholders and each Note Rating Agency.

Except as described in the preceding paragraph, NSM may not assign or delegate any of its rights or obligations under this Base Indenture or any other Transaction Document.

The Indenture Trustee

Section 11.1. Certain Duties and Responsibilities.

(a)The Indenture Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Base Indenture with respect to the Notes, and no implied covenants, duties

(including fiduciary duties) or obligations will be read into this Base Indenture against the Indenture Trustee.

(b)In the absence of bad faith on its part, the Indenture Trustee may, with respect to Notes, conclusively rely upon certificates or opinions furnished to the Indenture Trustee and conforming to the requirements of this Base Indenture, as to the truth of the statements and the correctness of the opinions expressed therein; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Indenture Trustee, the Indenture Trustee will be under a duty to examine the same to determine whether or not they conform on their face to the requirements of this Base Indenture but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein.

(c)If an Event of Default has occurred and is continuing, with respect to the Notes of which a Responsible Officer of the Indenture Trustee has been given written notice in the manner set forth in this Indenture or of which a Responsible Officer of the Indenture Trustee has actual knowledge, the Indenture Trustee will exercise such of the rights and powers vested in it by this Base Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs; provided that the foregoing shall not be deemed to require the Indenture Trustee to take any action, or have any liability for the failure to take any action, where the terms of this Base Indenture or any Supplement provide that the Indenture Trustee only takes action at the direction of a certain percentage of the Noteholders or other Person or if the Indenture Trustee is permitted to refrain from taking action unless it has been provided with adequate indemnity.

(d)No provision of this Base Indenture will be construed to relieve the Indenture Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(i)this subsection (d) will not be construed to limit the effect of subsection (a) of this Section 11.1;

(ii)the Indenture Trustee will not be liable for any error of judgment made in good faith by an Indenture Trustee Authorized Officer, unless it will be proved that the Indenture Trustee was negligent in ascertaining the pertinent facts;

(iv)no provision of this Base Indenture will require the Indenture Trustee 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 or powers, if it has reasonable grounds for believing that repayment of such funds or indemnity satisfactory to the Indenture Trustee against such risk or liability is not reasonably assured to it;

(v)whether or not therein expressly so provided, every provision of this Base Indenture relating to the conduct or affecting the liability of or affording protection to the Indenture Trustee will be subject to the provisions of this Section; and

(vi)the Indenture Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Issuer or of Noteholders, as applicable, in accordance with the terms of this Indenture, relating to the time, method or place of conducting any proceeding for any remedy available to the Indenture Trustee or with respect to the exercise of any trust or power conferred upon such party under this Indenture or with respect to the Notes.

Except as otherwise provided in Section 3.3(b), within ninety (90) days after the occurrence of any Event of Default hereunder,

(a)the Indenture Trustee will transmit by mail to all registered Noteholders, as their names and addresses appear in the Note Register, notice of such default hereunder known to the Indenture Trustee, and

(b)the Indenture Trustee will give prompt written notification thereof to each Note Rating Agency, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of or interest on any Note of any Series or Class, the Indenture Trustee will be protected in withholding such notice if and so long as an Indenture Trustee Responsible Officer in good faith determines that the withholding of such notice is in the interests of the Noteholders of such Series or Class. For the purpose of this Section, the term “default” means any event which is, or after notice or lapse of time or both would become, an Event of Default.

(c)The Indenture Trustee shall give to the subordinated holders party to the Intercreditor Agreement concurrently with the giving thereof to NSM a copy of any written notice by the Indenture Trustee of the occurrence of an Event of Default or the occurrence of a transfer of Issuer responsibility. Notwithstanding the foregoing, in conducting any public or private sale under the UCC, the Indenture Trustee shall give to the subordinated holders party to the Intercreditor Agreement at least 10 days’ notice of such sale ; provided, that 10 days’ notice shall be deemed to be commercially reasonable notice.

(9)the Servicer also authorizes the Administrative Agent, at any time and from time to time, to execute, in connection with the sale provided for in Section 8.15 hereof, any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral; provided that the exercise of such powers are in accordance with the Acknowledgment Agreement; and

Section 11.6. Money Held in Trust.

(i)with respect to any such claim, the Indenture Trustee shall have given the Administrator written notice thereof promptly after a Responsible Officer of the Indenture Trustee shall have actual knowledge thereof; provided, however that failure to give such written notice shall not affect the Trust Estate’s or the Administrator’s obligation to indemnify the Indenture Trustee, unless such failure materially prejudices the Trust Estate’s or the Administrator’s rights;

(ii)the Administrator may, at its option, assume the defense of any such claim using counsel reasonably satisfactory to the Indenture Trustee; and

(iii)notwithstanding anything in this Base Indenture to the contrary, the Administrator shall not be liable for settlement of any claim by the Indenture Trustee, as the case may be, entered into without the prior consent of the Administrator, which consent shall not be unreasonably withheld.

Notwithstanding the foregoing, in no event shall the Trust Estate or the Administrator be required to indemnify the Indenture Trustee if the indemnification obligation under this Section 11.7 is the result of gross negligence or willful misconduct by the Indenture Trustee.

No termination of this Base Indenture, or the resignation or removal of the Indenture Trustee, shall affect the obligations created by this Section 11.7(b) of the Administrator to indemnify the Indenture Trustee under the conditions and to the extent set forth herein.

Notwithstanding the foregoing, the indemnification provided in this Section 11.7(b) with respect to the Administrator shall not pertain to any loss, liability or expense of the Indenture Trustee, including the costs and expenses of defending itself against any claim, incurred in connection with any actions taken by the Indenture Trustee at the direction of the Noteholders pursuant to the terms of this Base Indenture.

The Indenture Trustee agrees fully to perform its duties under this Base Indenture notwithstanding its failure to receive any payments of Indenture Trustee Fees pursuant to this Section 11.7(b) subject to its rights to resign in accordance with the terms of this Base Indenture.

Anything in this Base Indenture to the contrary notwithstanding, in no event shall the Indenture Trustee (in any of its capacities) be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Indenture Trustee has been advised of the likelihood of such a loss or damage and regardless of the form of action.

The Securities Intermediary, the Paying Agent, the Custodian and the Calculation Agent shall be indemnified by the Trust Estate pursuant to Section 4.5 and Section 8.6, and secondarily by the Administrator, in respect of the matters described in Section 4.9 to the same extent as the Indenture Trustee.

Neither of the Indenture Trustee nor the Securities Intermediary will have any recourse to any asset of the Issuer or the Trust Estate other than funds available pursuant to Section 4.5 and Section 8.6 or to any Person other than the Issuer (or the Administrator pursuant to this Section 11.7). Except as specified in Section 4.5 and Section 8.6, any such payment to the Indenture Trustee shall be subordinate to payments to be made to Noteholders.

The Indenture Trustee is not responsible for any action or inaction of the Administrative Agent.

If such bank or corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such bank or corporation will be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Issuer may not, nor may any Person directly or indirectly Controlling, Controlled by, or under common Control with the Issuer, serve as Indenture Trustee. If at any time the Indenture Trustee ceases to be eligible in accordance with the provisions of this Section 11.8, it shall resign upon failure to obtain such confirmation within a reasonable time (not to exceed thirty (30) Business Days) after such ineligibility in the manner and with the effect hereinafter specified in this Article.

Section 11.9. Resignation and Removal; Appointment of Successor.

(b)The Indenture Trustee and the bank serving as Indenture Trustee (in all capacities) may resign with respect to all, but not less than all, such capacities and all, but not less than all of the Outstanding Notes at any time by giving written notice thereof to the Issuer. If an instrument of acceptance by a successor Indenture Trustee, Calculation Agent, Paying Agent or Securities Intermediary shall not have been delivered to the Indenture Trustee within thirty (30) days after the giving of such notice of resignation, the resigning Indenture Trustee, Calculation Agent, Paying Agent or Securities Intermediary may petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary.

(c)The Indenture Trustee or Calculation Agent may be removed with respect to all Outstanding Notes at any time by Action of the Majority Noteholders of all Outstanding Notes, delivered to the Indenture Trustee and to the Issuer. Removal of the Indenture Trustee shall also constitute removal of the Calculation Agent, Securities Intermediary and Paying Agent hereunder, to the extent the Indenture Trustee serves in such a capacity at the time of such resignation. If an instrument of acceptance by a successor Indenture Trustee or Calculation Agent shall not have been delivered to the Indenture Trustee within thirty (30) days after the giving of such notice of removal, the Indenture Trustee or Calculation Agent being removed may petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee or Calculation Agent.

(i)the Indenture Trustee ceases to be eligible under Section 11.8 and fails to resign after written request therefore by the Issuer or by any Noteholder; or

(ii)the Indenture Trustee becomes incapable of acting with respect to any Series or Class of Notes; or

(iii)the Indenture Trustee is adjudged bankrupt or insolvent or a receiver of the Indenture Trustee or of its property is appointed or any public officer takes charge or Control of the Indenture Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

(e)If the Indenture Trustee or Calculation Agent resigns, is removed or becomes incapable of acting with respect to any Notes, or if a vacancy shall occur in the office of the Indenture Trustee or Calculation Agent for any cause, the Issuer, subject to the Administrative Agent’s consent, will promptly

appoint a successor Indenture Trustee or Calculation Agent. If, within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a successor Indenture Trustee or Calculation Agent is appointed by Act of the Majority Noteholders of all Outstanding Notes, delivered to the Issuer and the retiring Indenture Trustee or Calculation Agent, the successor Indenture Trustee or Calculation Agent so appointed will, forthwith upon its acceptance of such appointment, become the successor Indenture Trustee or Calculation Agent and supersede the successor Indenture Trustee or Calculation Agent appointed by the Issuer. If no successor Indenture Trustee or Calculation Agent shall have been so appointed by the Issuer or the Noteholders and accepted appointment in the manner hereinafter provided, any Noteholder who has been a bona fide Noteholder of a Note for at least six (6) months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Indenture Trustee or Calculation Agent.

(f)The Issuer will give written notice of each resignation and each removal of the Indenture Trustee and each appointment of a successor Indenture Trustee to each Noteholder as provided in Section 1.7 and to each Note Rating Agency that is then rating Outstanding Notes. To facilitate delivery of such notice, upon request by the Issuer, the Note Registrar shall provide to the Issuer a list of the relevant registered Noteholders. Each notice will include the name of the successor Indenture Trustee and the address of its principal Corporate Trust Office.

Section 11.10. Acceptance of Appointment by Successor.

Every successor Indenture Trustee appointed hereunder will execute, acknowledge and deliver to the Issuer and to the predecessor Indenture Trustee an instrument accepting such appointment, with a copy to each Note Rating Agency then rating any Outstanding Notes, and thereupon the resignation or removal of the predecessor Indenture Trustee will become effective, and such successor Indenture Trustee, without any further act, deed or conveyance, will become vested with all the rights, powers, trusts and duties of the predecessor Indenture Trustee, Calculation Agent, Securities Intermediary and Paying Agent; but, on request of the Issuer or the successor Indenture Trustee, such predecessor Indenture Trustee will, upon payment of its reasonable charges, if any, execute and deliver an instrument transferring to such successor Indenture Trustee all the rights, powers and trusts of the predecessor Indenture Trustee, Calculation Agent, Securities Intermediary and Paying Agent, and will duly assign, transfer and deliver to such successor Indenture Trustee all property and money held by such predecessor Indenture Trustee hereunder, subject nevertheless to its rights to payment pursuant to Section 11.7. Upon request of any such successor Indenture Trustee, the Issuer will execute any and all instruments for more fully and certainly vesting in and confirming to such successor Indenture Trustee all such rights, powers and trusts.

No successor Indenture Trustee will accept its appointment unless at the time of such acceptance such successor Indenture Trustee will be qualified and eligible under this Article XI.

Section 11.11. Merger, Conversion, Consolidation or Succession to Business.

Any Person into which the Indenture Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which the Indenture Trustee shall be a party, or any Person succeeding to all or substantially all of the corporate trust business of the Indenture Trustee, will be the successor of the Indenture Trustee hereunder, provided that such Person shall be otherwise qualified and eligible under this Article XI, without the execution or filing of any paper or any further act on the part of any of the parties hereto. The Indenture Trustee will give prompt written notice of such merger, conversion, consolidation or succession to the Issuer and each Note Rating Agency that is then rating Outstanding Notes. If any Notes shall have been authenticated, but

not delivered, by the Indenture Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Indenture Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Indenture Trustee had itself authenticated such Notes.

Section 11.12. Appointment of Authenticating Agent.

At any time when any of the Notes remain Outstanding the Indenture Trustee, with the approval of the Issuer, may appoint an Authenticating Agent with respect to one or more Series or Classes of Notes which will be authorized to act on behalf of the Indenture Trustee to authenticate Notes of such Series or Classes issued upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 6.5, and Notes so authenticated will be entitled to the benefits of this Base Indenture and will be valid and obligatory for all purposes as if authenticated by the Indenture Trustee hereunder. Wherever reference is made in this Base Indenture to the authentication and delivery of Notes by the Indenture Trustee or an Indenture Trustee authorized signatory or to the Indenture Trustee’s Certificate of Authentication, such reference will be deemed to include authentication and delivery on behalf of the Indenture Trustee by an Authenticating Agent and a Certificate of Authentication executed on behalf of the Indenture Trustee by an Authenticating Agent. Each Authenticating Agent will be acceptable to the Issuer and will at all times be a Person organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as an Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and, if other than the Issuer itself, subject to supervision or examination by a federal or state authority of the United States. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent will be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent will cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent will resign immediately in the manner and with the effect specified in this Section.

Any Person into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Authenticating Agent will be a party, or any Person succeeding to the corporate agency or corporate trust business of an Authenticating Agent, will continue to be an Authenticating Agent, provided that such Person will be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Indenture Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Indenture Trustee and to the Issuer. The Indenture Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Issuer. Upon receiving such a notice of resignation or upon such a termination, or if at any time such Authenticating Agent ceases to be eligible in accordance with the provisions of this Section, the Indenture Trustee, with the approval of the Issuer, may appoint a successor Authenticating Agent which will be acceptable to the Issuer and will give notice to each Noteholder as provided in Section 1.7. Any successor Authenticating Agent upon acceptance of its appointment hereunder will become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent will be appointed unless eligible under the provisions of this Section.

The Indenture Trustee agrees to pay to each Authenticating Agent (other than an Authenticating Agent appointed at the request of the Issuer, the Noteholders or the Administrator from time to time or appointed due to a change in law or other circumstance beyond the Indenture Trustee’s control)

reasonable compensation for its services under this Section, out of the Indenture Trustee’s own funds without reimbursement pursuant to this Base Indenture. The Indenture Trustee shall be the initial Authenticating Agent.

(c)The Notes of any Series or Class of Notes shall be subject to optional redemption under this Article XIII, in whole but not in part, by the Issuer, through (i) the use of the proceeds of issuance and sale of a new Series of Notes issued hereunder, or (ii) the use of the proceeds received of any amounts funded under any Variable Funding Notes on any Business Day after the date on which the related Revolving Period ends, and on any Business Day within ten (10) days prior to the end of such Revolving Period or at other times specified in the related Indenture Supplement upon ten (10) days’ (or other times specified in the related Indenture Supplement) prior notice to the Indenture Trustee and the Noteholders.

(e)If necessary to avoid a Borrowing Base Deficiency, the Notes of any Series or Class of Variable Funding Notes shall be subject to repayment by the Issuer, in whole or in part, up to the amount necessary to avoid a Borrowing Base Deficiency, using any other cash or funds of the Issuer other than Collections on the Participation Certificates, upon one (1) Business Day’s prior notice from the Issuer to the Indenture Trustee and the related VFN Noteholders. Any such repayment pursuant to this Section 13.1(e) shall reduce the principal balance of such Variable Funding Notes but shall not result in a reduction of any funding commitments related thereto or the Maximum VFN Principal Balance thereof (unless otherwise agreed between the Noteholders of such Variable Funding Notes and the Issuer) and (ii) may be made on a non-pro rata basis with other Series of Variable Funding Notes.

(f)Notwithstanding any other provision of this Base Indenture, the early redemption rights of the Issuer set forth in this Section 13.1 are in addition to, the Issuer’s rights set forth in Section 2.1(b)(ii) to remove as Collateral the Participation Certificates and Mortgage Pools.

Section 13.2. Notice.

The Issuer, by entering into this Base Indenture, each Noteholder, by its acceptance of a Note and each purchaser of a beneficial interest therein, by accepting such beneficial interest, agree to treat such Notes (to the extent outstanding for United States federal income tax purposes) (other than any Retained Note) as debt for United States federal, state and local income and franchise tax purposes, unless otherwise required by applicable law in a proceeding of final determination. The Indenture Trustee shall treat the Trust Estate as a security device only. The provisions of this Base Indenture shall be construed in furtherance of the foregoing intended tax treatment.

Section 14.4. Alternate Payment Provisions.

Notwithstanding any provision of this Base Indenture or any of the Notes to the contrary, the Issuer, with the written consent of the Indenture Trustee and the Paying Agent, may enter into any agreement with any Noteholder of a Note providing for a method of payment or notice that is different from the methods provided for in this Base Indenture for such payments or notices. The Issuer will furnish to the Indenture Trustee and the Paying Agent a copy of each such agreement and the Indenture Trustee and the Paying Agent will cause payments or notices, as applicable, to be made in accordance with such agreements.

Section 14.5. Termination of Obligations.

The respective obligations and responsibilities of the Indenture Trustee created hereby (other than the obligation of the Indenture Trustee to make payments to Noteholders as hereinafter set forth) shall terminate upon satisfaction and discharge of this Base Indenture as set forth in Article VII, except with respect to the payment obligations described in Section 14.6(b). Upon this event, the Indenture Trustee shall release, assign and convey to the Issuer or any of its designees, without recourse, representation or warranty, all of its right, title and interest in the Collateral, whether then existing or thereafter created, all monies due or to become due and all amounts received or receivable with respect thereto (including all moneys then held in any Trust Account) and all proceeds thereof, except for amounts held by the Indenture Trustee pursuant to Section 14.6(b). The Indenture Trustee shall execute and deliver such instruments of transfer and assignment as shall be provided to it, in each case without recourse, as shall be reasonably requested by the Issuer to vest in the Issuer or any of its designees all right, title and interest which the Indenture Trustee had in the Collateral.

Section 14.6. Final Payment.

(a)The Issuer shall give the Indenture Trustee at least ten (10) days’ prior written notice of the Payment Date on which the Noteholders of any Series or Class may surrender their Notes for payment of the final payment on and cancellation of such Notes. Not later than the fifth (5th) day prior to the Payment Date on which the final payment in respect of such Series or Class is payable to Noteholders, the Indenture Trustee or the Paying Agent shall provide notice to Noteholders of such Series or Class specifying (i) the date upon which final payment of such Series or Class will be made upon presentation and surrender of Notes of such Series or Class at the office or offices therein designated, (ii) the amount of any such final payment and (iii) that the Record Date otherwise applicable to such payment date is not applicable, payments being made only upon presentation and surrender of such Notes at the office or offices therein specified. The Indenture Trustee shall give such notice to the Note Registrar and the Paying Agent at the time such notice is given to Noteholders.

(b)Notwithstanding a final payment to the Noteholders of any Series or Class (or the termination of the Issuer), except as otherwise provided in this paragraph, all funds then on deposit in any account allocated to such Noteholders shall continue to be held in trust for the benefit of such Noteholders, and the Paying Agent or the Indenture Trustee shall pay such funds to such Noteholders upon surrender of their Notes, if such Notes are Definitive Notes. In the event that all such Noteholders shall not surrender their Notes for cancellation within six (6) months after the date specified in the notice from the Indenture Trustee described in clause (a) above, the Indenture Trustee shall give a second (2nd) notice to the remaining such Noteholders to surrender their Notes for cancellation and receive the final payment with respect thereto. If within one year after the second (2nd) notice all such Notes shall not have been surrendered for cancellation, the Indenture Trustee may take appropriate steps, or may appoint an agent to take appropriate steps, to contact the remaining such Noteholders concerning surrender of their Notes, and the cost thereof (including costs related to giving the second (2nd) notice) shall be paid out of the funds in the Collection and Funding Account. The Indenture Trustee and the Paying Agent shall pay to the Issuer any monies held by them for the payment of principal or interest that remains unclaimed for two (2) years. After payment to the Issuer, Noteholders entitled to the money must look to the Issuer for payment as general creditors unless an applicable abandoned property law designates another Person.

Section 14.7. Base Servicing Fee.

The parties hereto acknowledge that so long as no Event of Default has occurred and is continuing, NSM has the right to withdraw the Base Servicing Fee with respect to any Mortgage Loan out of collections it receives pursuant to the Ginnie Mae Contract with respect to such Mortgage Loan.

Section 14.8. Owner Trustee Limitation of Liability.

It is expressly understood and agreed by the parties hereto that (a) this Base Indenture is executed and delivered by Wilmington Trust, National Association, not individually or personally but solely as trustee of the Issuer, in the exercise of the powers and authority conferred and vested in it, (b) each of the representations, warranties, undertakings and agreements herein made on the part of the Issuer is made and intended not as personal representations, warranties, undertakings and agreements by Wilmington Trust, National Association but is made and intended for the purpose of binding only the Issuer, (c) nothing herein contained shall be construed as creating any liability on Wilmington Trust, National Association, individually or personally, to perform any covenant either expressed or implied contained herein, all such liability, if any, being expressly waived by the parties hereto and by any Person claiming by, through or under the parties hereto,

(d) Wilmington Trust, National Association, has made no investigation as to the accuracy or completeness of any representations or warranties made by the Issuer in this Base Indenture and

(e) under no circumstances shall Wilmington Trust, National Association, be personally liable for the payment of any indebtedness or expenses of the Issuer or be liable for the breach or failure of any obligation, representation, warranty or covenant made or undertaken by the Issuer under this Base Indenture or any other related documents.

Section 14.9. Communications with Rating Agencies.

If the Servicer, the Administrative Agent or the Indenture Trustee shall receive any written or oral communication from any Note Rating Agency (or any of the respective officers, directors or employees of any Note Rating Agency) with respect to the transactions contemplated hereby or under the Transaction Documents or in any way relating to the Notes, the Servicer, the Administrative Agent and the Indenture Trustee agree to refrain from communicating with such Note Rating Agency and to promptly notify the Administrator of such communication; provided, however, that if the Servicer, the Administrative Agent or the Indenture Trustee receives an oral communication from a Note Rating Agency, the Servicer, the Administrative Agent or the Indenture Trustee, as the case may be, is authorized to refer such Note Rating Agency to the Administrator, who will respond to such oral communication. At the written request of the Administrator, the Servicer, the Administrative Agent and the Indenture Trustee agree to cooperate with the Administrator to provide certain information to the Administrator that may be reasonably required by a Note Rating Agency to rate or to perform ratings surveillance on the Notes, and acknowledge and agree that the Administrator shall be permitted, in turn, to provide such information to the Note Rating Agencies via the internet address identified therefor by the Administrator; provided, that the Servicer, the Administrative Agent and the Indenture Trustee shall only be required to provide such information that is reasonably available to such party at the time of request. Notwithstanding any other provision of this Base Indenture or the other Transaction Documents, under no circumstances shall the Servicer, the Administrative Agent or the Indenture Trustee be required to participate in telephone conversations or other oral communications with a Note Rating Agency, nor shall the Servicer, the Administrative Agent or the Indenture Trustee be prohibited from communicating with any nationally recognized statistical rating organization about matters other than the Notes or the transactions contemplated hereby or by the Transaction Documents. Furthermore, the Indenture Trustee may make statements to Noteholders available on its website (as contemplated by Section 3.5(a) hereof), and such action is not prohibited by this Section 14.9.

Section 14.10. Authorized Representatives.

Each individual designated as an authorized representative of the Indenture Trustee, Calculation Agent, Paying Agent and Securities Intermediary, NSM, the Administrative Agents, the Issuer and the Credit Manager (each, an “Authorized Representative”), is authorized to give and receive notices, requests and instructions and to deliver certificates and documents in connection with this Base Indenture on behalf of each of the Indenture Trustee, Calculation Agent, Paying Agent, Securities Intermediary, NSM, the Administrative Agents, Issuer and the Credit Manager, respectively, and the specimen signature for each such Authorized Representative of the Indenture Trustee, Calculation Agent, Paying Agent, Securities Intermediary, NSM, the Administrative Agents, the Issuer and the Credit Manager initially authorized hereunder is set forth on Exhibits C-1, C-2, C-3, C-4 and C-5, respectively. From time to time, the Indenture Trustee, the Calculation Agent, the Paying Agent, the Securities Intermediary, NSM, the Administrative Agents, the Issuer and the Credit Manager may, by delivering to the others a revised exhibit, change the information previously given pursuant to this Section 14.10, but each of the parties

hereto shall be entitled to rely conclusively on the then current exhibit until receipt of a superseding exhibit.

Section 14.11. Performance of the Issuer’s Duties by the Owner Trustee and the Administrator.

(a)The parties hereto hereby acknowledge and agree (i) that certain duties of the Issuer will be performed on behalf of the Issuer by the Administrator pursuant to the Administration Agreement and hereby acknowledge and accept the terms of such agreement as of the date hereof and (ii) except as expressly set forth herein, the Owner Trustee shall have no duty or obligation to perform the obligations of the Issuer hereunder or to monitor the compliance of the Issuer with the terms hereof.

(b)Any successor to the Owner Trustee appointed pursuant to the terms of the Trust Agreement (or any corporation into which the Owner Trustee may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Owner Trustee shall be a party) shall be the successor Owner Trustee under the Trust Agreement for purposes of this Base Indenture without the execution or filing of any paper, instrument or further act to be done on the part of the parties hereto.

Section 14.12. Noteholder or Note Owner Communications with the Indenture Trustee.

A Noteholder (if the Notes are represented by Definitive Notes) or a Note Owner (if the Notes are represented by Book-Entry Notes) may communicate with the Indenture Trustee and give notices and make requests and demands and give directions to the Indenture Trustee through the procedures of the Depository and by notifying the Indenture Trustee and providing to the Indenture Trustee a copy of the communication such Noteholder or Note Owner, as applicable, proposes to send. Any Note Owner must provide written certification stating that the Note Owner is a beneficial owner of a Note, together with supporting documentation such as a trade confirmation, an account statement, a letter from a broker or dealer verifying ownership or another similar document evidencing ownership of a Note. The Indenture Trustee will not be required to take action in response to requests, demands or directions of a Noteholder or a Note Owner, unless the Noteholder or Note Owner has offered reasonable security or indemnity reasonably satisfactory to the Indenture Trustee to protect it against the fees and expenses that it may incur in complying with the request, demand or direction.

Section 14.13. Joinder of the Acknowledgment Agreement.

Each party hereto acknowledges, and each Noteholder and any party with a participation or other interest in any of the Notes, is hereby deemed a joinder party to the Acknowledgment Agreement for the limited purpose of acknowledging and agreeing that its interests in the Servicing Rights (as defined in the Acknowledgment Agreement) and in all reimbursements for Advances (as defined in the Acknowledgment Agreement) and Servicing Income (as defined in the Acknowledgment Agreement) in respect of the Servicing Rights are subject to the terms of the Acknowledgment Agreement and shall be subordinate in all respects to the rights and powers of Ginnie Mae thereunder and under the Ginnie Mae Contract. Without limiting the generality of the foregoing, each Noteholder and any party with a participation or other interest in any of the Notes is deemed to confirm that it shall have no rights under, and that pursuant to this Indenture it has waived (and hereby waives) any and all rights under or pursuant to, the Acknowledgment Agreement in respect of the Security Agreement (as defined in the Acknowledgment Agreement), the Security Interest (as defined in the Acknowledgment Agreement) and the Participation Certificates; provided, that the foregoing shall not be interpreted as a waiver of such entity’s rights under and pursuant to the Security Agreement, nor as a waiver of its rights in respect of the Security Interest.

Section 14.14. Confidentiality.

Each Party agrees to maintain the confidentiality of all information received from the other Parties relating to such Parties and their respective businesses (the “Information”), except that Information may be disclosed: (i) to its Affiliates (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (ii) to the extent required or requested by Ginnie Mae or any regulatory authority purporting to have jurisdiction over such Person (including any self-regulatory authority); (iii) to the extent required by any applicable law or regulations or by any subpoena, court order or similar legal process; (iv) in connection with the exercise of any remedies hereunder or under any other Transaction Documents or any suit, action or proceeding relating to this Indenture or any other Transaction Documents or the enforcement of its rights hereunder or thereunder; (v) to (x) any actual or potential assignee, transferee or participant in connection with the assignment or transfer by such Party of any loans or any participations therein or (y) any actual or prospective party to any swap, derivative or other transaction under which payments are to be made by reference to such Party or any Affiliates or any of their respective obligations, this Indenture or payments hereunder; provided that, any such potential assignee, transferee, participant, swap counterparty or advisor is advised of, and agrees in writing to be bound by, the provisions of this Section; (vi) with the consent of the other Parties; or (vii) to the extent such Information (x) is or becomes publicly available other than as a result of a breach of this Section or (y) is available to the Parties on a non-confidential basis prior to disclosure by the other Parties or any of their respective Affiliates, or (z) becomes available to a Party or any of its Affiliates on a non-confidential basis from a source other than the other Parties.
