Mortgage Loan Schedule

This POOLING AND SERVICING AGREEMENT, dated as of December 1, 2006 (the "Agreement"), by and among J.P. MORGAN ACCEPTANCE CORPORATION I, a Delaware corporation, as depositor (the "Depositor"), U.S. BANK NATIONAL ASSOCIATION, as trustee (the "Trustee") and WELLS FARGO BANK, N.A., in its dual capacities as master servicer (the "Master Servicer") and securities administrator (the "Securities Administrator")  and acknowledged by J.P. MORGAN MORTGAGE ACQUISITION CORP., a Delaware corporation, as seller (the "Seller"), for purposes of Sections 2.04 and 2.05 and JPMORGAN CHASE BANK, NATIONAL ASSOCIATION, a national banking association and THE BANK OF NEW YORK TRUST COMPANY, N.A., a national banking association, as custodians (each a "Custodian and together, the "Custodians"), for purposes of Sections 11.06, 11.07 and 11.09.

PRELIMINARY STATEMENT

The Depositor has acquired the Mortgage Loans from the Seller and at the Closing Date is the owner of the Mortgage Loans and the other property being conveyed by the Depositor to the Trustee hereunder for inclusion in the Trust Fund.  On the Closing Date, the Depositor will acquire the Certificates from the Trustee as consideration for the Depositor’s transfer to the Trust Fund of the Mortgage Loans and the other property constituting the Trust Fund.  The Depositor has duly authorized the execution and delivery of this Agreement to provide for the conveyance to the Trustee of the Mortgage Loans and the other property constituting the Trust Fund.  All covenants and agreements made by the Depositor, the Master Servicer, the Securities Administrator and the Trustee herein, with respect to the Mortgage Loans and the other property constituting the Trust Fund, are for the benefit of the Holders from time to time of the Certificates.  The Depositor, the Trustee, the Master Servicer and the Securities Administrator are entering into this Agreement, and the Trustee is accepting the Trust Fund created hereby, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged.

As provided herein, the Trustee shall elect that the Trust Fund (exclusive of the Yield Maintenance Agreement and the Reserve Fund) be treated for federal income tax purposes as comprising three real estate mortgage investment conduits (each, a "REMIC"): Lower-Tier REMIC 1, Middle-Tier REMIC 1 and Upper-Tier REMIC 1.    Each Certificate, other than the Residual Certificates, shall represent ownership of a regular interest in Upper-Tier REMIC 1 for purposes of the REMIC Provisions.  

Lower-Tier REMIC 1 shall hold the assets of the Trust Fund (other than the Yield Maintenance Agreement and the Reserve Fund) and shall issue several uncertificated interests, including the LT-R-1 Interest, which is hereby designated as the sole residual interest in Lower-Tier REMIC 1.  Each remaining uncertificated interest in Lower-Tier REMIC 1 is hereby designated as a REMIC regular interest.

Middle-Tier REMIC 1 shall hold the uncertificated REMIC regular interests issued by Lower-Tier REMIC 1 and shall issue several uncertificated interests, including the MT-R-1 Interest, which is hereby designated as the sole residual interest in Middle-Tier REMIC 1.  Each remaining uncertificated interest in Middle-Tier REMIC 1 is hereby designated as a REMIC regular interest.

Upper-Tier REMIC 1 shall hold the uncertificated REMIC regular interests issued by Middle-Tier REMIC 1.  Each of the Certificates (other than the Class A-R Certificate and the Exchangeable Certificates) and the Uncertificated REMIC Interests represent ownership of regular interests in Upper-Tier REMIC 1.  Upper-Tier REMIC 1 shall also issue the Class A-R Certificate, which is hereby designated as the sole residual interest in Upper-Tier REMIC 1.

The latest possible maturity date of all REMIC regular interests created in this Agreement shall be the Latest Possible Maturity Date.

The Lower-Tier REMIC 1

The Lower Tier Interests in Lower-Tier REMIC 1 shall have the class designations, initial principal amounts, interest rates and corresponding Pool, Subgroup or Class of Certificates as set forth in the following table:

_______________

(1)

Each Class A Interest will have a principal balance initially equal to 0.9% of the Pool Subordinate Amount or Subgroup Subordinate Amount, as applicable in each case, the ("SP"), of its corresponding Pool or Subgroup, as applicable.  Each Class B Interest will have a principal balance initially equal to 0.1% of the Pool Subordinate Amount or Subgroup Subordinate Amount, as applicable, of its corresponding Pool or Subgroup, as applicable. The initial principal balance of each Class C Interest will equal the excess of the initial aggregate principal balance of its corresponding Pool or Subgroup, as applicable (less the initial principal balance of any principal-only interest in the Lower-Tier REMIC 1 payable from such Pool or Subgroup) over the initial aggregate principal balances of the Class A and Class B Interests corresponding to such Pool or Subgroup, as applicable.

(2)

This interest shall be an interest-only regular interest and shall bear interest on its notional principal amount, which shall be equal at all times to the Class Notional Amount of the Class A-X Certificates.

(3)

This Lower Tier Interest shall have an initial principal balance equal to the initial principal balance of its Corresponding Class of Certificates.

(4)

This Lower Tier Interest shall bear interest at the same rate as the Certificate Interest Rate of its Corresponding Class of Certificates.

(5)

The Class LT-R-1 Interest is the sole class of residual interest in the Lower-Tier REMIC 1. It has no principal balance and pays no principal or interest.  

On each Distribution Date, the Available Distribution Amount shall be distributed with respect to the Lower Tier Interests in the following manner:

(1)

Interest shall be distributed with respect to each Lower-Tier Interest at the rate, or according to the formulas, described above;

(2)

Principal if no Cross-Over Situation Exists. If no Cross-Over Situation exists with respect to any Class of Interests, then Principal Amounts arising with respect to each Pool or Subgroup, as applicable, will be allocated: first to cause the Pool's or Subgroup’s, as applicable, corresponding Class A and Class B to equal, respectively, 0.9% of the related SP and 0.1% of the SP; and second to the Pool's or Subgroup’s, as applicable, corresponding Class C Interest;

(3)

Principal if a Cross-Over Situation Exists. If a Cross-Over Situation exists with respect to the Class A and Class B Interests then:

(a)

if the Calculation Rate in respect of the outstanding Class A and Class B Interests relating to a Group of Subordinate Certificates would be less than the Certificate Interest Rate of such Group of Subordinate Certificates, Principal Relocation Payments will be made proportionately to the outstanding Class A Interests prior to any other Principal Distributions from each such Pool or Subgroup, as applicable; and

(b)

if the Calculation Rate in respect of the outstanding Class A and Class B Interests would be greater than the Certificate Interest Rate of such Group of Subordinate Certificates, Principal Relocation Payments will be made proportionately to the outstanding Class B Interests prior to any other Principal Distributions from each such Pool or Subgroup, as applicable.

In each case, Principal Relocation Payments will be made so as to cause the Calculation Rate in respect of the outstanding Class A and Class B Interests relating to a Group of Subordinate Certificates to equal the Certificate Interest Rate of such Group or Subordinate Certificates. With respect to each Pool or Subgroup, as applicable, if (and to the extent that) the sum of (a) the principal payments comprising the Principal Remittance Amount received during the Due Period and (b) the Realized Losses, are insufficient to make the necessary reductions of principal on the Class A and Class B Interests, then interest will be added to the Pool's or Subgroup’s, as applicable, other Interests that are not receiving Principal Relocation Payments, in proportion to their principal balances.

(c)

The outstanding aggregate Class A and Class B Interests for all Pools and Subgroups will not be reduced below 1 percent of the excess of (i) the aggregate outstanding Class Principal Amounts of all Pools and Subgroups as of the end of any Due Period over (ii) the Senior Certificates for all Pools and Subgroups as of the related Distribution Date (after taking into account distributions of principal on such Distribution Date).

(d)

If (and to the extent that) the limitation in paragraph (c) prevents the distribution of principal to the Class A and Class B Interests of a Pool or Subgroup, as applicable, and if the Pool's or Subgroup’s, as applicable, Class C Interest has already been reduced to zero, then the excess principal from that Pool or Subgroup, as applicable, will be paid to the Class C Interests of the other Pool or Subgroup, as applicable, the aggregate Class A and Class B Interests of which are less than one percent of the Pool Subordinate Amount or Subgroup Subordinate Amount, as applicable. If the Pool or Subgroup, as applicable, of the Class C Interest that receives such payment has a weighted average Net Mortgage Rate below the weighted average Net Mortgage Rate of the Pool making the payment, then the payment will be treated by the Lower-Tier REMIC 1 as a Realized Loss. Conversely, if the Pool or Subgroup, as applicable, of the Class C Interest that receives such payment has a weighted average Net Mortgage Rate above the weighted average Net Mortgage Rate of the Pool or Subgroup, as applicable, making the payment, then the payment will be treated by the Lower-Tier REMIC 1 as a reimbursement for prior Realized Losses.

On each Distribution Date, Prepayment Penalties with respect to the Mortgage Loans shall be distributed to the Class LT1-P Interest, which shall be entitled to receive its principal balance on the same Distribution Date that principal is payable to the Class P Certificates.

MIDDLE-TIER REMIC 1

The Lower-Tier Interests in Middle-Tier REMIC 1 shall have the class designations, initial principal amounts, interest rates and corresponding Pool, Subgroup or Class of Certificates as set forth in the following table:

(1) This Lower-Tier Interest shall have an interest rate equal to that of its Corresponding Class of Certificates.

(2) This Lower-Tier Interest shall have an initial principal amount equal to that of its Corresponding Class of Certificates (or, in the case of the Class MT1-A-1 and Class MT1-A-8 Interests, the Class A-1 and Class A-8 Certificates, respectively.)

(3)  The Class MT-R-1 Interest is the sole class of residual interest in the Middle-Tier REMIC 1. It has no principal balance and pays no principal or interest.

(4)  This Lower-Tier Interest shall not have a principal balance but shall bear interest on its notional principal balance which shall be equal at all times to the Class A-X Notional Amount.

On each Distribution Date, the Available Distribution Amount with respect to Aggregate Pool I shall be distributed with respect to the Lower Tier Interests in Middle-Tier REMIC 1 in the following manner:

(1)

Interest shall be distributed with respect to each Lower-Tier Interest at the rate, or according to the formulas, described above;

(2)

Principal and Realized Losses shall be allocated to each Lower-Tier Interest in an amount equal to that allocable to each Corresponding Class of Certificates for such Lower-Tier Interest on such Distribution Date.

On each Distribution Date, the Class MT1-P Interest shall be entitled to receive all amounts distributed with respect to the Class LT1-P Interest.

The Certificates

The following table sets forth (or describes) the Class designation, Certificate Interest Rate, initial Class Principal Amount (or initial Class Notional Amount) and minimum denomination for each Class of Certificates comprising interests in the Trust Fund created hereunder and the Exchangeable Certificates.

_______________

(1)

On each Distribution Date, the Certificate Interest Rate on the Class A-1 Certificates will be equal to LIBOR plus the related Certificate Margin, subject to a minimum Certificate Interest Rate of 0.550% per annum and a maximum Certificate Interest Rate of 9.500% per annum.  Any interest payable on the Class A-1 Certificates in excess of the interest payable to such Classes at a Certificate Interest Rate of 6.000% per annum will be payable solely from amounts received in respect of the Yield Maintenance Agreement.  After the Distribution Date in March 2011, the maximum Certificate Interest Rate applicable to the Class A-1 Certificates is 6.00% per annum.

(2)

The Certificate Interest Rate on the Class A-2 Certificates will be equal to the excess of (a) 5.450% over (b) LIBOR, but not less than 0.000% per annum.

(3)

Interest will accrue on the Class A-2 Notional Amount.

(4)

On each Distribution Date, the Certificate Interest Rate on the Class A-8 Certificates will be equal to LIBOR plus the related Certificate Margin, subject to a minimum Certificate Interest Rate of 0.380% per annum and a maximum Certificate Interest Rate of 7.000% per annum.

(5)

The Certificate Interest Rate on the Class A-9 Certificates will be equal to the excess of (a) 6.620% over (b) LIBOR, but not less than 0.000% per annum.

(6)

Interest will accrue on the Class A-9 Notional Amount.

(7)

The Class A-P Certificates will not receive any distributions of interest.

(8)

The Certificate Interest Rate applicable to each of the Class M, Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates will equal a per annum rate calculated as the quotient expressed as a percentage of (a) the sum of (i) the product of (x) 5.500% and (y) the Subgroup Subordinate Amount relating to Subgroup 1 for that Distribution Date, (ii) the product of (x) 6.000% and (y) the Subgroup Subordinate Amount relating to Subgroup 2 for that Distribution Date and (iii) the product of (x) 7.000% and (y) the Subgroup Subordinate Amount relating to Subgroup 3 for that Distribution Date, divided by (b) the aggregate of the Subgroup Subordinate Amounts relating to each Subgroup for that Distribution Date.

(9)

The Class P Certificates will be entitled to all prepayment penalties on the Mortgage Loans.

(10)

These classes shall be issued in uncertificated form and shall constitute theUncertificated REMIC Interests.    Each Class of Exchangeable REMIC Certificates issued under the Trust Agreement will be entitled to the same distributions of principal and interest as the corresponding Uncertificated REMIC Interest.

(11)

The Class A-13 Certificates are Exchangeable Certificates which will not be issued under this Pooling and Servicing Agreement.

(12)

The Class A-X Certificates will not receive any distributions of principal.  Interest will accrue on the Class A-X Notional Amount, which is initially equal to $2,169,341.22.

As of the Cut-off Date, the Mortgage Loans had an Aggregate Stated Principal Balance of $778,192,218.26.  

The foregoing REMIC structure is intended to cause all of the cash from the Mortgage Loans to flow through to Upper-Tier REMIC 1 as cash flow on a REMIC regular interest, without creating any shortfall—actual or potential (other than for credit losses) to any REMIC regular interest.  To the extent that the structure is believed to diverge from such intention the parties identifying such ambiguity shall notify the other parties hereto and the parties involved will resolve such ambiguities to accomplish such result and will to the extent necessary rectify any drafting errors or seek clarification to the structure without Certificateholder approval (but with guidance of Counsel) to accomplish such intention, making any amendments in accordance with Section 12.03 of this Agreement.

It is intended that the conveyance of the Depositor’s right, title and interest in and to property constituting the Trust Fund pursuant to this Agreement shall constitute, and shall be construed as, a sale of such property and not a grant of a security interest to secure a loan.  However, if such conveyance is deemed to be in respect of a loan, it is intended that: (1) the rights and obligations of the parties shall be established pursuant to the terms of this Agreement; (2) the Depositor hereby grants to the Trustee for the benefit of the Holders of the Certificates a first priority security interest in all of the Depositor’s right, title and interest in, to and under, whether now owned or hereafter acquired, the Trust Fund and all proceeds of any and all property constituting the Trust Fund to secure payment of the Certificates; and (3) this Agreement shall constitute a security agreement under applicable law.  If such conveyance is deemed to be in respect of a loan and the trust created by this Agreement terminates prior to the satisfaction of the claims of any Person holding any Certificate, the security interest created hereby shall continue in full force and effect and the Trustee shall be deemed to be the collateral agent for the benefit of such Person, and all proceeds shall be distributed as herein provided.

(b)

The Depositor shall, to the extent consistent with this Agreement, take such reasonable actions as may be necessary to ensure that, if this Agreement were deemed to create a security interest in the Mortgage Loans and the other property described above, such security interest would be deemed to be a perfected security interest of first priority under applicable law and will be maintained as such throughout the term of this Agreement.  The Depositor will, at its own expense, make all initial filings on or about the Closing Date and shall forward a copy of such filing or filings to the Trustee.  Without limiting the generality of the foregoing, the Depositor shall prepare and forward for filing, or shall cause to be forwarded for filing, at the expense of the Depositor, all filings necessary to maintain the effectiveness of any original filings necessary under the relevant UCC to perfect the Trustee’s security interest in or lien on the Mortgage Loans, including without limitation (x) continuation statements, and (y) such other statements as may be occasioned by (1) any change of name of an Originator, the Depositor or the Trustee, (2) any change of location of the place of business or the chief executive office of the Seller or the Depositor, (3) any transfer of any interest of an Originator or the Depositor in any Mortgage Loan or (4) any change under the relevant UCC or other applicable laws.  Neither the Originators nor the Depositor shall organize under the law of any jurisdiction other than the State under which each is organized as of the Closing Date (whether changing its jurisdiction of organization or organizing under an additional jurisdiction) without giving 30 days prior written notice of such action to its immediate and intermediate transferee, including the Trustee.  Before effecting such change, any Originator or the Depositor proposing to change its jurisdiction of organization shall prepare and file in the appropriate filing office any financing statements or other statements necessary to continue the perfection of the interests of its immediate and mediate transferees, including the Trustee, in the Mortgage Loans.  In connection with the transactions contemplated by this Agreement, each of the Originators and the Depositor authorizes its immediate or mediate transferee to file in any filing office any initial financing statements, any amendments to financing statements, any continuation statements, or any other statements or filings described in this paragraph (b), it being understood that such immediate or mediate transferees are under no obligation to make such filings.

SECTION 3.03

Transfer and Exchange of Certificates.  

(a)

A Definitive Certificate (other than Book-Entry Certificates which shall be subject to Section 3.09 hereof) may be transferred by the Holder thereof only upon presentation and surrender of such Certificate at the office of the Certificate Registrar duly endorsed or accompanied by an assignment duly executed by such Holder or his duly authorized attorney in such form as shall be satisfactory to the Certificate Registrar.  Upon the transfer of any Definitive Certificate in accordance with the preceding sentence, the Trustee or the Securities Administrator on behalf of the Trustee shall execute, and the Authenticating Agent shall authenticate and deliver to the transferee, one or more new Certificates of the same Class and evidencing, in the aggregate, the same aggregate Certificate Principal Amount (or Notional Amount) as the Certificate being transferred.  An Uncertificated Interest or Uncertificated REMIC Interest may be transferred by the Holder thereof upon written notice to the Certificate Registrar, satisfaction of the other conditions set forth in this Section 3.03 and, with respect to the Uncertificated REMIC Interests, the consent of the Depositor.  No service charge shall be made to a Certificateholder for any registration of transfer of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any registration of transfer of Certificates.

(b)

A Definitive Certificate (other than Book-Entry Certificates which shall be subject to Section 3.09 hereof) may be exchanged by the Holder thereof for any number of new Certificates of the same Class, in authorized denominations, representing in the aggregate the same Certificate Principal Amount (or Notional Amount) as the Certificate surrendered, upon surrender of the Certificate to be exchanged at the office of the Certificate Registrar duly endorsed or accompanied by a written instrument of transfer duly executed by such Holder or his duly authorized attorney in such form as is satisfactory to the Certificate Registrar.  Definitive Certificates delivered upon any such exchange will evidence the same obligations, and will be entitled to the same rights and privileges, as the Certificates surrendered.  No service charge shall be made to a Certificateholder for any exchange of Certificates, but the Certificate Registrar may require payment of a sum sufficient to cover any tax or governmental charge that may be imposed in connection with any exchange of Certificates.  Whenever any Definitive Certificates are so surrendered for exchange, the Trustee, or the Securities Administrator on behalf of the Trustee, shall execute, and the Authenticating Agent shall authenticate, date and deliver the Certificates which the Certificateholder making the exchange is entitled to receive.

(c)

By acceptance of a Restricted Certificate, whether upon original issuance or subsequent transfer, each Holder of such a Certificate acknowledges the restrictions on the transfer of such Certificate set forth thereon and agrees that it will transfer such a Certificate only as provided herein.

The following restrictions shall apply with respect to the transfer and registration of transfer of a Restricted Certificate:

(ii)

The Certificate Registrar shall register the transfer of a Restricted Certificate if the requested transfer is being made to an "accredited investor" under Rule 501(a)(1), (2), (3) or (7) under the Act, or to any Person all of the equity owners in which are such accredited investors, by a transferor who furnishes to the Certificate Registrar a letter of the transferee substantially in the form of Exhibit I hereto.

(d)

No transfer of an ERISA-Restricted Certificate in the form of a Definitive Certificate or that is an Uncertificated Interest shall be made to any Person or shall be effective unless the Certificate Registrar, on behalf of the Trustee, has received (A) a certificate substantially in the form of Exhibit J hereto (or Exhibit B, in the case of a Residual Certificate) from such transferee or (B) an Opinion of Counsel satisfactory to the Trustee and the Certificate Registrar to the effect that the purchase and holding of such a Certificate will not constitute or result in any nonexempt prohibited transactions under Title I of ERISA or Section 4975 of the Code and will not subject the Certificate Registrar, the Trustee, the Master Servicer, any Servicer, the Depositor or the Securities Administrator to any obligation in addition to those undertaken in the Agreement; provided, however , that the Certificate Registrar will not require such certificate or opinion in the event that, as a result of a change of law or otherwise, counsel satisfactory to the Certificate Registrar has rendered an opinion to the effect that the purchase and holding of an ERISA-Restricted Certificate by an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA, or Section 4975 of the Code, (collectively, a "Plan") or a Person that is purchasing or holding such a Certificate with the assets of a Plan will not constitute or result in a prohibited transaction under Title I of ERISA or Section 4975 of the Code and will not subject the Certificate Registrar, the Trustee, the Master Servicer, the Depositor, the Securities Administrator or any Servicer to any obligation in addition to those undertaken in this Agreement.  Each Transferee of an ERISA-Restricted Certificate that is a Book-Entry Certificate shall be deemed to have made the representations set forth in Exhibit J.  The preparation and delivery of the certificate and opinions referred to above shall not be an expense of the Trust Fund, the Certificate Registrar, the Trustee, the Master Servicer, any Servicer the Depositor or the Securities Administrator.

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

(e)

As a condition of the registration of transfer or exchange of any Certificate, the Certificate Registrar may require the certified taxpayer identification number of the owner of the Certificate and the payment of a sum sufficient to cover any tax or other governmental charge imposed in connection therewith; provided, however , that the Certificate Registrar shall have no obligation to require such payment or to determine whether or not any such tax or charge may be applicable.  No service charge shall be made to the Certificateholder for any registration, transfer or exchange of a Certificate.

(f)

Notwithstanding anything to the contrary contained herein, no Residual Certificate may be owned, pledged or transferred, directly or indirectly, by or to (i) a Disqualified Organization or (ii) an individual, corporation or partnership or other person unless such person is (A) not a Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate in connection with the conduct of a trade or business within the United States and has furnished the transferor and the Certificate Registrar with an effective Internal Revenue Service Form W 8ECI or successor form at the time and in the manner required by the Code (any such person who is not covered by clause (A) or (B) above is referred to herein as a "Non-permitted Foreign Holder").

Prior to and as a condition of the registration of any transfer, sale or other disposition of a Residual Certificate, the proposed transferee shall deliver to the Trustee and the Certificate Registrar an affidavit in substantially the form attached hereto as Exhibit B representing and warranting, among other things, that such transferee is neither a Disqualified Organization, an agent or nominee acting on behalf of a Disqualified Organization, nor a Non-permitted Foreign Holder (any such transferee, a "Permitted Transferee"), and the proposed transferor shall deliver to the Trustee and the Certificate Registrar an affidavit in substantially the form attached hereto as Exhibit C.  In addition, the Trustee or the Certificate Registrar may (but shall have no obligation to) require, prior to and as a condition of any such transfer, the delivery by the proposed transferee of an Opinion of Counsel, addressed to the Trustee and the Certificate Registrar, that such proposed transferee or, if the proposed transferee is an agent or nominee, the proposed beneficial owner, is not a Disqualified Organization, agent or nominee thereof, or a Non-permitted Foreign Holder.  Notwithstanding the registration in the Certificate Register of any transfer, sale, or other disposition of a Residual Certificate to a Disqualified Organization, an agent or nominee thereof, or Non-permitted Foreign Holder, such registration shall be deemed to be of no legal force or effect whatsoever and such Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign Holder shall not be deemed to be a Certificateholder for any purpose hereunder, including, but not limited to, the receipt of distributions on such Residual Certificate.  The Depositor, the Certificate Registrar and the Trustee shall be under no liability to any Person for any registration or transfer of a Residual Certificate to a Disqualified Organization, agent or nominee thereof or Non-permitted Foreign Holder or for the Paying Agent making any payments due on such Residual Certificate to the Holder thereof or for taking any other action with respect to such Holder under the provisions of the Agreement, so long as the transfer was effected in accordance with this Section 3.03(f), unless the Certificate Registrar shall have actual knowledge at the time of such transfer or the time of such payment or other action that the transferee is a Disqualified Organization, or an agent or nominee thereof, or Non-permitted Foreign Holder.  The Certificate Registrar shall be entitled to recover from any Holder of a Residual Certificate that wa
