MORTGAGE PASS-THROUGH CERTIFICATE

evidencing a fractional undivided interest in the distributions allocable to the Class 1-A-[1][2][3][4][5] Certificates with respect to a trust fund generally consisting of one pool of conventional, hybrid adjustable-rate and fixed rate first lien residential mortgage loans (the “Group I Loans”), and three pools of conventional fixed-rate first lien residential mortgage loans (the “Group II Loans”), in each case, secured by one- to four- family residences, units in planned unit developments, co-ops and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC. The Certificates are limited in right of payment to certain collections and recoveries respecting the related Group I Loans and payments received pursuant to the Group I Certificate Swap Agreement, as more specifically set forth herein and in the Agreement.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING GROUP I LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

This certifies that [Cede & Co.] is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in certain assets of the Trust Fund sold by Deutsche Alt-A Securities, Inc. (the “Depositor”).  This Certificate is primarily backed by the Group I Loans sold by PHH Mortgage Corporation and Bishop’s Gate Residential Mortgage Trust to the Depositor.  Wells Fargo Bank, N.A. will act as master servicer of the Group I Loans (the “Master Servicer”, which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on [the Business Day prior to the related Distribution Date][the last Business Day of the month immediately preceding the month in which the related Distribution Date occurs] (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class 1-A-[1][2][3][4][5] Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class 1-A-[1][2][3][4][5] Certificates or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate with respect to Class 1-A-[1][2][3][4][5] Certificates for each Distribution Date through and including the Group I Optional Termination Date will be the lesser of (i) One-Month LIBOR plus the applicable margin set forth in the Agreement for such Class and (ii) the related Net WAC Pass-Through Rate; provided, however, that the margins applicable to each of the Group I Senior Certificates will increase by 100% on the Distribution Date following the first possible Group I Optional Termination Date with respect to the Group I Loans.

This Certificate is one of a duly authorized issue of Certificates designated as Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and representing a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the related Group I Loans and payments received pursuant to the Group I Certificate Swap Agreement, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group I Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interests of all Certificates (with the consent of the Certificate Swap Provider only with respect to matters affecting the Group I Certificate Swap Agreement).  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group I Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all of the Group I Loans and all property acquired in respect of such Group I Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group I Loans and all property acquired in respect of any Group I Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates relating to the applicable Group I Loan; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group I Loans and the fair market value of each related REO Property remaining in the Trust Fund with respect to the Group I Loans at the time of purchase, being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group I Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assumes any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on [the Business Day prior to the related Distribution Date][the last Business Day of the month immediately preceding the month in which the related Distribution Date occurs]  (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class 2-A-[1][2][3][4][5][6] Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class 2-A-[1][2][3][4][5][6] Certificates or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register.

The Pass-Through Rate with respect to the Class 2-A-[1][2][3][4][5][6] Certificates on any Distribution Date shall be equal to [6.000% per annum][ One-Month LIBOR plus the applicable margin set forth in the Agreement for such Class][36.600% minus the product of (a) one-month LIBOR and (b) 6][5.450% over One-Month LIBOR].

This Certificate is one of a duly authorized issue of Certificates designated as a Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and represents a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group II Loans and certain other assets of the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group II Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interests of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group II Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Group II Loans and all property acquired in respect of such Group II Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group II Loans and all property acquired in respect of any Group II Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group II Loans and the fair market value of each REO Property remaining in the Trust Fund with respect to the Group II Loans at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group II Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assumes any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class  3-A-[1][2] Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class  3-A-[1][2] Certificates or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate with respect to the Class  3-A-[1][2] Certificates on any Distribution Date shall be equal to 6.000% per annum.

This Certificate is one of a duly authorized issue of Certificates designated as a Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and represents a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group II Loans and certain other assets of the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group II Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interests of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group II Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Group II Loans and all property acquired in respect of such Group II Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group II Loans and all property acquired in respect of any Group II Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group II Loans and the fair market value of each REO Property remaining in the Trust Fund with respect to the Group II Loans at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group II Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assumes any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

evidencing a fractional undivided interest in the distributions allocable to the Class 4-A-1 Certificates with respect to a trust fund generally consisting of one pool of conventional,  hybrid adjustable-rate and fixed-rate first lien residential mortgage loans (the “Group I Loans”), and three pool of conventional fixed-rate first lien residential mortgage loans (the “Group II Loans”), in each case, secured by one- to four- family residences, units in planned unit developments, co-ops and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC. The Certificates are limited in right of payment to certain collections and recoveries respecting the related Group II Loans.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING GROUP II LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

This certifies that [Cede & Co.] is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in certain assets of the Trust Fund sold by Deutsche Alt-A Securities, Inc. (the “Depositor”).  This Certificate is primarily backed by the Group II Loans sold by PHH Mortgage Corporation and Bishop’s Gate Residential Mortgage Trust to the Depositor.  Wells Fargo Bank, N.A. will act as master servicer of the Group II Loans (the “Master Servicer”, which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class  4-A-1 Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class  4-A-1 Certificates or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate with respect to the Class  4-A-1 Certificates on any Distribution Date shall be equal to 6.000% per annum.

This Certificate is one of a duly authorized issue of Certificates designated as a Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and represents a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group II Loans and certain other assets of the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group II Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interests of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group II Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Group II Loans and all property acquired in respect of such Group II Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group II Loans and all property acquired in respect of any Group II Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group II Loans and the fair market value of each REO Property remaining in the Trust Fund with respect to the Group II Loans at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group II Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assumes any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

PHH ALTERNATIVE MORTGAGE TRUST, SERIES 2007-2

MORTGAGE PASS-THROUGH CERTIFICATE

evidencing a fractional undivided interest in the distributions allocable to the Class [2][4]PO Certificates with respect to a trust fund generally consisting of a pool of conventional, hybrid adjustable-rate and fixed-rate first lien residential mortgage loans (the “Group I Loans”), and three pools of conventional fixed-rate first lien residential mortgage loans (the “Group II Loans”), in each case, secured by one- to four- family residences, units in planned unit developments, co-ops and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING GROUP II LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

This certifies that [Cede & Co.] is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in certain assets of the Trust Fund sold by Deutsche Alt-A Securities, Inc. (the “Depositor”). This Certificate is primarily backed by the Group II Loans sold by PHH Mortgage Corporation and Bishop’s Gate Residential Mortgage Trust to the Depositor.  Wells Fargo Bank, N.A. will act as master servicer of the Group II Loans (the “Master Servicer”, which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the calendar month preceding the month of such Distribution Date (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class [2][4]PO Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

This Certificate is one of a duly authorized issue of Certificates designated as a Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and represents a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group II Loans and certain other assets of the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group II Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interests of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Group II Loans and all property acquired in respect of such Group II Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group II Loans and all property acquired in respect of any Group II Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group II Loans and the fair market value of each REO Property remaining in the Trust Fund with respect to the Group II Loans at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group II Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assumes any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

evidencing a fractional undivided interest in the distributions allocable to the Class II-AR Certificates with respect to a trust fund generally consisting of a pool of conventional, hybrid adjustable-rate and fixed-rate first lien residential mortgage loans (the “Group I Loans”), and three pools of conventional fixed-rate first lien residential mortgage loans (the “Group II Loans”), in each case, secured by one- to four- family residences, units in planned unit developments, co-ops and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

This certifies that [PHH Mortgage Corporation] is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in certain assets of the Trust Fund sold by Deutsche Alt-A Securities, Inc. (the “Depositor”).  The Group II Loans were sold by PHH Mortgage Corporation and Bishop’s Gate Residential Mortgage Trust to the Depositor.  Wells Fargo Bank, N.A. will act as master servicer of the Group II Loans (the “Master Servicer”, which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class II-AR Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class II-AR Certificates, or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate with respect to any Distribution Date shall be equal to 6.000% per annum.

This Certificate is one of a duly authorized issue of Certificates designated as a Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and represents a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group II Loans and certain other assets of the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group II Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interest of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

Each Holder of this Certificate will be deemed to have agreed to be bound by the restrictions set forth in the Agreement to the effect that (i) each person holding or acquiring any Ownership Interest in this Certificate must be a United States Person and a Permitted Transferee, (ii) the transfer of any Ownership Interest in this Certificate will be conditioned upon the delivery to the Securities Administrator of, among other things, an affidavit to the effect that it is a United States Person and Permitted Transferee, (iii) any attempted or purported transfer of any Ownership Interest in this Certificate in violation of such restrictions will be absolutely null and void and will vest no rights in the purported transferee, and (iv) if any person other than a United States Person and a Permitted Transferee acquires any Ownership Interest in this Certificate in violation of such restrictions, then the Depositor will have the right, in its sole discretion and without notice to the Holder of this Certificate, to sell this Certificate to a purchaser selected by the Depositor, which purchaser may be the Depositor, or any affiliate of the Depositor, on such terms and conditions as the Depositor may choose.

No transfer of this Certificate to a Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person using “Plan Assets” to acquire this Certificate shall be made except in accordance with Section 6.3(e) of the Agreement.

Prior to registration of any transfer, sale or other disposition of this Certificate, the proposed transferee shall provide to the Securities Administrator (i) an affidavit to the effect that such transferee is any Person other than a Disqualified Organization or the agent (including a broker, nominee or middleman) of a Disqualified Organization, and (ii) a certificate that acknowledges that (A) the Class II-AR Certificates have been designated as a representing the beneficial ownership of the residual interests in each Group II REMIC, (B) it will include in its income a pro rata share of the net income of the Trust Fund and that such income may be an “excess inclusion,” as defined in the Code, that, with certain exceptions, cannot be offset by other losses or benefits from any tax exemption, and (C) it expects to have the financial means to satisfy all of its tax obligations including those relating to holding the Class II-AR Certificates. Notwithstanding the registration in the Certificate Register of any transfer, sale or other disposition of this Certificate to a Disqualified Organization or an agent (including a broker, nominee or middleman) of a Disqualified Organization, such registration shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Certificateholder for any purpose, including, but not limited to, the receipt of distributions in respect of this Certificate.

The Holder of this Certificate, by its acceptance hereof, shall be deemed to have consented to the provisions of Section 6.3(e) of the Agreement and to any amendment of the Agreement deemed necessary by counsel of the Depositor to ensure that the transfer of this Certificate to any Person other than a Permitted Transferee or any other Person will not cause any portion of the Trust Fund to cease to qualify as a REMIC or cause the imposition of a tax upon any REMIC.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group II Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Group II Loans and all property acquired in respect of such Group II Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group II Loans and all property acquired in respect of any Group II Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group II Loans and the fair market value of each REO Property remaining in the Trust Fund with respect to the Group II Loans at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group II Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assume any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

MORTGAGE PASS-THROUGH CERTIFICATE

evidencing a fractional undivided interest in the distributions allocable to the Class 1-M Certificates with respect to a trust fund generally consisting of a pool of conventional, hybrid adjustable-rate and fixed-rate first lien residential mortgage loans (the “ Group I Loans”), and three pools of conventional fixed-rate first lien residential mortgage loans (the “Group II Loans”), in each case, secured by one- to four- family residences, units in planned unit developments, co-ops and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC. The Certificates are limited in right of payment to certain collections and recoveries respecting the related Group I Mortgage Loans and payments received pursuant to the Group I Certificate Swap Agreement, all as more specifically set forth herein and in the Agreement.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING GROUP I LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

This certifies that [Cede & Co.] is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in certain assets of the Trust Fund sold by Deutsche Alt-A Securities, Inc. (the “Depositor”). This Certificate is primarily backed by the Group I Loans sold by PHH Mortgage Corporation and Bishop’s Gate Residential Mortgage Trust to the Depositor. Wells Fargo Bank, N.A. will act as master servicer of The Group I Loans (the “Master Servicer”, which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the Business Day prior to the related Distribution Date (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class 1-M-[1][2][3][4] Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class 1-M-[1][2][3][4] Certificates, or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate on the Class 1-M-[1][2][3][4] Certificates for each Distribution Date through and including the Group I Optional Termination Date will be the lesser  of (i) One-Month LIBOR plus the applicable margin set forth in the Agreement for such Class  and (ii) the related Net WAC Pass-Through Rate; provided, however, that the margins applicable to each of the Class 1-M-[1][2][3][4] Certificates will increase by 50% on the Distribution Date following the first possible Group I Optional Termination Date with respect to the Group I Loans. 

This Certificate is one of a duly authorized issue of Certificates designated as Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and representing a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the related Group I Mortgage Loans and payments received pursuant to the Certificate Swap Agreement, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to The Group I Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interests of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group I Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all of the Group I Loans and all property acquired in respect of such Group I Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all The Group I Loans and all property acquired in respect of any Mortgage Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates relating to the applicable Loan; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Loans and the fair market value of each related REO Property remaining in the Trust Fund with respect to the Group I Loans at the time of purchase, being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group I Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assumes any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class II-B-[1][2][3] Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class II-B-[1][2][3] Certificates, or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate on the Class II-B-[1][2][3] Certificates is equal to 6.00% per annum.  

This Certificate is one of a duly authorized issue of Certificates designated as a Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and represents a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group II Loan and certain other assets of the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group II Loan.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interest of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

Any transferee of this Certificate shall be deemed to make the representations set forth in Section 6.3(e) of the Agreement.  

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group II Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Group II Loans and all property acquired in respect of such Group II Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group II Loans and all property acquired in respect of any Group II Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group II Loans and the fair market value of each REO Property remaining in the Trust Fund with respect to the Group II Loans at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group II Loan as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assume any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

MORTGAGE PASS-THROUGH CERTIFICATE

evidencing a fractional undivided interest in the distributions allocable to the Class II-B-[4][5][6]Certificates with respect to a trust fund generally consisting of a pool of conventional,  hybrid adjustable-rate and fixed-rate first lien residential mortgage loans (the “Group I Loans”), and three pools of conventional fixed-rate first lien residential mortgage loans (the “Group II Loans”), in each case, secured by one- to four- family residences, units in planned unit developments, co-ops and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC. The Certificates are limited in right of payment to certain collections and recoveries respecting the related Group II Loans.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING GROUP II LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

This certifies that [PHH Mortgage Corporation] is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in certain assets of the Trust Fund sold by Deutsche Alt-A Securities, Inc. (the “Depositor”). The  Group II Loans were sold by PHH Mortgage Corporation and Bishop’s Gate Residential Mortgage Trust to the Depositor.  Wells Fargo Bank, N.A. will act as master servicer of the Group II Loan (the “Master Servicer”, which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class II-B-[4][5][6] Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class II-B-[4][5][6] Certificates, or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

The Pass-Through Rate on the Class II-B-[4][5][6] Certificates is equal to 6.00% per annum.  

This Certificate is one of a duly authorized issue of Certificates designated as a Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and represents a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group II Loans and certain other assets of the Trust Fund, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group II Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interest of all Certificates.  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

No transfer of this Certificate shall be made unless the transfer is made pursuant to an effective registration statement under the Securities Act, and an effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event that such a transfer of this Certificate is to be made without registration or qualification, the Securities Administrator shall require receipt of (i) if such transfer is purportedly being made in reliance upon Rule 144A or Regulation S under the Securities Act, written certifications from the Holder of the Certificate desiring to effect the transfer, and from such Holder’s prospective transferee, substantially in the forms attached to the Agreement as Exhibits F and E, respectively, (ii) if such transfer is purportedly being made in reliance upon Rule 501(a) under the Securities Act, written certifications from the Holder of the Certificate desiring to effect the transfer and from such Holder’s prospective transferee, substantially in the form attached to the Agreement as Exhibit D and (iii) in all other cases, an Opinion of Counsel satisfactory to it that such transfer may be made without such registration or qualification (which Opinion of Counsel shall not be an expense of the Trust Fund or of the Depositor, the Trustee, the Master Servicer or the Securities Administrator in their respective capacities as such), together with copies of the written certification(s) of the Holder of the Certificate desiring to effect the transfer and/or such Holder’s prospective transferee upon which such Opinion of Counsel is based. None of the Depositor, the Trustee or the Securities Administrator is obligated to register or qualify the Class of Certificates specified on the face hereof under the Securities Act or any other securities law or to take any action not otherwise required under the Agreement to permit the transfer of such Certificates without registration or qualification.  Any Holder desiring to effect a transfer of this Certificate shall be required to indemnify the Trustee, the Depositor, the Master Servicer and the Securities Administrator against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

No transfer of this Certificate shall be made to any person unless the Transferee provides a certification pursuant to Section 6.3(e) of the Agreement.  

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of all the Group II Loans and all property acquired in respect of such Group II Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group II Loans and all property acquired in respect of any Group II Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group II Loans and the fair market value of each REO Property remaining in the Trust Fund with respect to the Group II Loans at the time of purchase being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group II Loans as of the Cut-Off Date.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class I-CE Certificates, or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, the Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

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

No transfer of this Certificate shall be made unless the transfer is made pursuant to an effective registration statement under the Securities Act, and an effective registration or qualification under applicable state securities laws, or is made in a transaction that does not require such registration or qualification. In the event of any such transfer in reliance upon an exemption from the 1933 Act and such state securities laws, in order to assure compliance with the 1933 Act and such state securities laws, the Certificateholder desiring to effect such Transfer and such Certificateholder’s prospective Transferee shall each certify to the Trustee and the Securities Administrator in writing the facts surrounding the Transfer in substantially the forms set forth in Exhibit D (the “Transferor Certificate”) and (x) deliver a letter in substantially the form of either Exhibit E (the “Investment Letter”) or Exhibit F (the “Rule 144A Letter”) or (y) there shall be delivered to the Depositor and the Securities Administrator an Opinion of Counsel acceptable to and in form reasonably satisfactory to the Depositor and the Securities Administrator that such Transfer may be made pursuant to an exemption from the Securities Act, which Opinion of Counsel shall not be an expense of the Depositor, the Master Servicer, the Securities Administrator or the Trustee.  None of the Depositor, the Trustee or the Securities Administrator is obligated to register or qualify the Class of Certificates specified on the face hereof under the Securities Act or any other securities law or to take any action not otherwise required under the Agreement to permit the transfer of such Certificates without registration or qualification.  Any Holder desiring to effect a transfer of this Certificate shall be required to indemnify the Trustee, the Depositor, the Master Servicer and the Securities Administrator against any liability that may result if the transfer is not so exempt or is not made in accordance with such federal and state laws.

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Group I Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of (A) all of the Group I Loans and all property acquired in respect of such Group I Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group I Loans and all property acquired in respect of any Group I Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates relating to the applicable Group I Loan; however, such right to purchase is subject to the aggregate Scheduled Principal Balance of the Group I Loans and the fair market value of each related REO Property remaining in the Trust Fund with respect to the Group I Loans at the time of purchase, being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group I Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assume any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

IN WITNESS WHEREOF, the Securities Administrator has caused this Certificate to be duly executed.

PHH ALTERNATIVE MORTGAGE TRUST , SERIES 2007-2

MORTGAGE PASS-THROUGH CERTIFICATE

evidencing a fractional undivided interest in the distributions allocable to the Class I-R  Certificates with respect to a trust fund generally consisting of a pool of conventional one- to four-family hybrid adjustable-rate and fixed-rate mortgage loans (the “Group I Loans”), and three pools of conventional fixed-rate first lien residential mortgage loans (the “Group II Loans”), in each case, secured by one- to four- family residences, units in planned unit developments, co-ops and individual condominium units (the “Trust Fund”) sold by DEUTSCHE ALT-A SECURITIES, INC.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN DEUTSCHE ALT-A SECURITIES, INC., THE MASTER SERVICER, THE SECURITIES ADMINISTRATOR, THE TRUSTEE, ANY SERVICER OR ANY OF THEIR RESPECTIVE AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING GROUP I LOANS ARE GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES.

This certifies that [Deutsche Bank Securities Inc.] is the registered owner of the Percentage Interest evidenced hereby in the beneficial ownership interest of Certificates of the same Class as this Certificate in certain assets of the Trust Fund generally consisting of the Group I Loans and related assets sold by Deutsche Alt-A Securities, Inc. (the “Depositor”).  The Group I Loans were sold by PHH Mortgage Corporation and Bishop’s Gate Residential Mortgage Trust to the Depositor.  Wells Fargo Bank, N.A. will act as master servicer of the Group I Loans (the “Master Servicer”, which term includes any successors thereto under the Agreement referred to below). The Trust Fund was created pursuant to the Pooling and Servicing Agreement dated as of the Cut-Off Date specified above (the “Agreement”), among the Depositor, Wells Fargo Bank, N.A., as Master Servicer and securities administrator (the “Securities Administrator”) and HSBC Bank USA, National Association as trustee (the “Trustee”), a summary of certain of the pertinent provisions of which is set forth hereafter. To the extent not defined herein, capitalized terms used herein shall have the meaning ascribed to them in the Agreement. This Certificate is issued under and is subject to the terms, provisions and conditions of the Agreement, to which Agreement the Holder of this Certificate by virtue of its acceptance hereof assents and by which such Holder is bound.

Pursuant to the terms of the Agreement, distributions will be made on the 25th day of each month or, if such 25th day is not a Business Day, the Business Day immediately following such 25th day (a “Distribution Date”), commencing on the First Distribution Date specified above, to the Person in whose name this Certificate is registered at the close of business on the last Business Day of the month immediately preceding the month in which such Distribution Date occurs (the “Record Date”), in an amount equal to the product of the Percentage Interest evidenced by this Certificate and the amount required to be distributed to the Holders of Class I-R Certificates on such Distribution Date pursuant to the Agreement.

All distributions to the Holder of this Certificate under the Agreement will be made or caused to be made by the Securities Administrator by wire transfer in immediately available funds to the account of the Person entitled thereto if such Person shall have so notified the Securities Administrator in writing at least five Business Days prior to the Record Date immediately prior to such Distribution Date and is the registered owner of Class I-R Certificates, or otherwise by check mailed by first class mail to the address of the Person entitled thereto, as such name and address shall appear on the Certificate Register. Notwithstanding the above, the final distribution on this Certificate will be made after due notice by the Securities Administrator of the pendency of such distribution and only upon presentation and surrender of this Certificate at the office or agency appointed by the Securities Administrator for that purpose as provided in the Agreement.

This Certificate is one of a duly authorized issue of Certificates designated as Mortgage Pass-Through Certificate of the Series specified on the face hereof (herein called the “Certificates”) and representing a Percentage Interest in the Class of Certificates specified on the face hereof equal to the denomination specified on the face hereof divided by the aggregate Certificate Principal Balance of the Class of Certificates specified on the face hereof.  The Certificates, in the aggregate, evidence the entire beneficial ownership interest in the Trust Fund formed pursuant to the Agreement.

The Certificates are limited in right of payment to certain collections and recoveries respecting the Group I Loans and payments received pursuant to the Swap Agreement, all as more specifically set forth herein and in the Agreement. As provided in the Agreement, withdrawals from the Protected Accounts and the Distribution Account may be made from time to time for purposes other than distributions to Certificateholders, such purposes including reimbursement of advances made, or certain expenses incurred, with respect to the Group I Loans.  

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Depositor, the Master Servicer, the Trustee, the Securities Administrator and the rights of the Certificateholders under the Agreement at any time by the Depositor, the Master Servicer, the Trustee and the Securities Administrator with the consent of the Holders of Certificates evidencing, in the aggregate, not less than 66-2/3% Percentage Interest of all Certificates (with the consent of the Certificate Swap Provider only with respect to matters affecting the Group I Certificate Swap Agreement).  Any such consent by the Holder of this Certificate shall be conclusive and binding on such Holder and upon all future Holders of this Certificate and of any Certificate issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent is made upon this Certificate.  The Agreement also permits the amendment thereof, in certain limited circumstances, without the consent of the Holders of any of the Certificates.

As provided in the Agreement and subject to certain limitations therein set forth, the transfer of this Certificate is registrable in the Certificate Register upon surrender of this Certificate for registration of transfer at the offices or agencies appointed by the Securities Administrator as provided in the Agreement, duly endorsed by, or accompanied by an assignment in the form below or other written instrument of transfer in form satisfactory to the Securities Administrator duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest will be issued to the designated transferee or transferees.

The Certificates are issuable in fully registered form only without coupons in Classes and denominations representing Percentage Interests specified in the Agreement. As provided in the Agreement and subject to certain limitations therein set forth, Certificates are exchangeable for new Certificates of the same Class in authorized denominations evidencing the same aggregate Percentage Interest, as requested by the Holder surrendering the same.

Each Holder of this Certificate will be deemed to have agreed to be bound by the restrictions set forth in the Agreement to the effect that (i) each person holding or acquiring any Ownership Interest in this Certificate must be a United States Person and a Permitted Transferee, (ii) the transfer of any Ownership Interest in this Certificate will be conditioned upon the delivery to the Securities Administrator of, among other things, an affidavit to the effect that it is a United States Person and Permitted Transferee, (iii) any attempted or purported transfer of any Ownership Interest in this Certificate in violation of such restrictions will be absolutely null and void and will vest no rights in the purported transferee, and (iv) if any person other than a United States Person and a Permitted Transferee acquires any Ownership Interest in this Certificate in violation of such restrictions, then the Depositor will have the right, in its sole discretion and without notice to the Holder of this Certificate, to sell this Certificate to a purchaser selected by the Depositor, which purchaser may be the Depositor, or any affiliate of the Depositor, on such terms and conditions as the Depositor may choose.

No transfer of this Certificate to a Plan subject to ERISA or Section 4975 of the Code, any Person acting, directly or indirectly, on behalf of any such Plan or any Person using “Plan Assets” to acquire this Certificate shall be made except in accordance with Section 6.3(e) of the Agreement.

Prior to registration of any transfer, sale or other disposition of this Certificate, the proposed transferee shall provide to the Securities Administrator (i) an affidavit to the effect that such transferee is any Person other than a Disqualified Organization or the agent (including a broker, nominee or middleman) of a Disqualified Organization, and (ii) a certificate that acknowledges that (A) the Class I-R Certificates have been designated as representing the beneficial ownership of the residual interests in each Group I REMIC, (B) it will include in its income a pro rata share of the net income of the Trust Fund and that such income may be an “excess inclusion,” as defined in the Code, that, with certain exceptions, cannot be offset by other losses or benefits from any tax exemption, and (C) it expects to have the financial means to satisfy all of its tax obligations including those relating to holding the Class I-R Certificates. Notwithstanding the registration in the Certificate Register of any transfer, sale or other disposition of this Certificate to a Disqualified Organization or an agent (including a broker, nominee or middleman) of a Disqualified Organization, such registration shall be deemed to be of no legal force or effect whatsoever and such Person shall not be deemed to be a Certificateholder for any purpose, including, but not limited to, the receipt of distributions in respect of this Certificate.

The Holder of this Certificate, by its acceptance hereof, shall be deemed to have consented to the provisions of Section 6.3(e) of the Agreement and to any amendment of the Agreement deemed necessary by counsel of the Depositor to ensure that the transfer of this Certificate to any Person other than a Permitted Transferee or any other Person will not cause any portion of the Trust Fund to cease to qualify as a REMIC or cause the imposition of a tax upon any REMIC.

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

The Depositor, the Master Servicer, the Trustee, the Securities Administrator and any agent of the Depositor, the Master Servicer, the Trustee or the Securities Administrator may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and none of the Depositor, the Master Servicer, the Trustee or the Securities Administrator nor any such agent shall be affected by notice to the contrary.

The obligations created by the Agreement and the Trust Fund created thereby shall terminate upon payment to the Certificateholders of all amounts held by the Securities Administrator and required to be paid to them pursuant to the Agreement following the earlier of (i) the final payment or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund and (ii) the purchase by the party designated in the Agreement at a price determined as provided in the Agreement of (A) all of the Group I Loans and all property acquired in respect of such Group I Loans. The Agreement permits, but does not require, the party designated in the Agreement to purchase all the Group I Loans and all property acquired in respect of any Group I Loan at a price determined as provided in the Agreement. The exercise of such right will effect early retirement of the Certificates relating to the applicable Loan; however, such right to purchase is subject to the aggregate Scheduled Principal Balanceof the Group I Loans, as applicable, and the fair market value of each related REO Property remaining in the Trust Fund with respect to the Group I Loans at the time of purchase, being less than or equal to 10% of the aggregate Scheduled Principal Balance of the Group I Loans as of the Cut-Off Date.

The recitals contained herein shall be taken as statements of the Depositor and neither the Trustee nor the Securities Administrator assume any responsibility for their correctness.

Unless the certificate of authentication hereon has been executed by the Securities Administrator, by manual signature, this Certificate shall not be entitled to any benefit under the Agreement or be valid for any purpose.

___

3.

For purposes of determining the aggregate amount of securities owned and/or invested on a discretionary basis by the Transferee, the Transferee used the cost of such securities to the Transferee and did not include any of the securities referred to in the preceding paragraph. Further, in determining such aggregate amount, the Transferee may have included securities owned by subsidiaries of the Transferee, but only if such subsidiaries are consolidated with the Transferee in its financial statements prepared in accordance with generally accepted accounting principles and if the investments of such subsidiaries are managed under the Transferee’s direction. However, such securities were not included if the Transferee is a majority-owned, consolidated subsidiary of another enterprise and the Transferee is not itself a reporting company under the Securities Exchange Act of 1934.

5.

The Transferee acknowledges that it is familiar with Rule 144A and understands that the Transferor and other parties related to the Certificates are relying and will continue to rely on the statements made herein because one or more sales to the Transferee may be in reliance on Rule 144A.

In addition, the Transferee agrees that the Transferee will not purchase securities for a third party unless the Transferee has obtained a current representation letter from such third party or taken other appropriate steps contemplated by Rule 144A to conclude that such third party independently meets the definition of “qualified institutional buyer” set forth in Rule 144A.

7.

The Transferee will notify each of the parties to which this certification is made of any changes in the information and conclusions herein. Until such notice is given, the Transferee’s purchase of the Certificates will constitute a reaffirmation of this certification as of the date of such purchase. In addition, if the Transferee is a bank or savings and loan as provided above, the Transferee agrees that it will furnish to such parties updated annual financial statements promptly after they become available.

          transactions contemplated hereby whether or not disclosed in this Agreement;  

		    (v)       any

to a settlement agreement executed prior to the date hereof and           included herein
as an Assigned Contract (as hereinafter defined);  

		    (vi)       any
liability or obligation arising from events occurring on or prior to the

          intellectual property rights of others, or (C) the failure to comply with any
          requirements of law or any requirements of governmental bodies or agencies
          having jurisdiction over the Corporation, the Acquired Assets or the conduct of

		    (vii)       any

		    (q)       Employee

		    (i)       Schedule
4(q)(i) is a complete and accurate list of all employee benefit plans           which the
Corporation and any of its ERISA Affiliates (as hereinafter defined)           maintain,

legally or otherwise, including, without limitation, any profit sharing,
          deferred compensation, bonus, payroll, sick leave, consulting, stock option,
          stock purchase, stock bonus, employee stock ownership plan (within the meaning

          change of control, disability, severance, insurance, welfare or incentive pay
          policy, agreement, practice or arrangement; any plan, agreement or arrangement
          if providing for fringe benefits or perquisites to employees, officers,
          directors or agents of the Corporation and any of its ERISA Affiliates,
          including but not limited to benefits relating to employer supplied

          benefit plan” (within the meaning of Section 3(3) of the Employee
          Retirement Income Security Act of 1974, as amended (“ERISA”) through
          the date of this Agreement) (herein referred to individually as “Plan”          and
collectively as “Plans”). For purposes of this Agreement,           “ERISA
Affiliate” means all Persons which are treated as being under           common
control with the Corporation, as the case may be or any ERISA Affiliate           under
Section 414(b), (c), (in) or (o) of the Internal Revenue Code of 1986, as
          amended (“Code”).  

		    (ii)       Neither
the Corporation nor any ERISA Affiliate has ever been obligated to file           an IRS
Form 5500 with respect to any Plan. True and complete copies of the           following
documents with respect to any Plan of the Corporation and each ERISA           Affiliate,
as applicable, have been delivered to Buyer: (A) the most recent Plan           document
and trust agreement (including any amendments thereto), (B) all summary           plan
descriptions, (C) a written description of each material non written Plan,           (D)
each written communication to employees intended to describe a Plan or any
          benefit provided by such Plan, and (E) all correspondence with the IRS, the
          Department of Labor and the Pension Benefit Guaranty Corporation           (“PBGC”)
concerning any controversy.  

		    (iii)       Each
Plan is and has been maintained in compliance in all material respects with
          applicable law, including but not limited to ERISA, and the Code and with any
          applicable contractual obligations.  

		    (iv)       No
Plan is subject to Section 412 of the Code.  

		    (v)       No
Plan is or ever has been subject to Title IV of ERISA.  

		    (vi)       There
are no pending or, to the knowledge of the Corporation, threatened claims,
          actions or lawsuits, other than routine claims for benefits in the ordinary
          course, asserted or instituted against (A) any Plan or its assets, or (B) any
          fiduciary with respect to any Plan for which the Corporation or any ERISA
          Affiliate may be directly or indirectly be liable, through indemnification
          obligations or otherwise.  

- 13 -

		    (vii)       Neither
the Corporation nor any ERISA Affiliate has ever contributed to or been
          obligated to contribute to any Plan that is a “multiemployer plan” as
          defined in Section 4001(a)(3) of ERISA or that is subject to Title IV of ERISA.  

		    (viii)       Neither
the Corporation nor any ERISA Affiliate has engaged, directly or           indirectly, in
a non-exempt prohibited transaction (as defined in Section 4975           of the Code or
Section 406 of ERISA) in connection with any Plan.  

		    (ix)       No
Plan is a nonqualified deferred compensation plan (as that term is used for
          purposes of Section 409A of the Code).  

		    (x)       During
the last two years there have been no amendments to any Plan, no written
          interpretation or announcement (whether or not written) by the Corporation or
          any ERISA Affiliate relating to any Plan, no Plan has been established, and
          there have been and are no negotiations, demands, or proposals which are
pending           that concern any Plan, which resulted in or could reasonably be
anticipated to           result in a material increase in (A) the accrued or promised
benefits of any           employees of the Corporation or any ERISA Affiliate and (B) the
level of expense           incurred in respect thereof.  

		    (xi)       Neither
the Corporation nor any ERISA Affiliate sponsors, maintains or has           obligations,
direct, contingent or otherwise, with respect to any Plan that is           subject to
the laws of any country other than the United States.  

		    (xii)       Neither
the Corporation nor any ERISA Affiliate sponsors, maintains or has           obligations,
direct, contingent or otherwise, with respect to any Plan that is           intended to
be a tax-qualified plan under Section 401 of the Code.  

		    (xiii)       Each
Plan that provides welfare benefits has been operated in compliance with           all
requirements of Sections 601 through 608 of ERISA and Section 4980B of           the
Code and regulations thereunder, relating to the continuation of coverage           under
certain circumstances in which coverage would otherwise cease. Neither the
          Corporation nor any ERISA Affiliate has contributed to a nonconforming group
          health plan (as defined under Code Section 5000(c)) and no ERISA Affiliate has
          incurred a tax under Section 5000(a) of the Code which could become a liability
          of the Corporation or any ERISA Affiliate. No retired or former employee of the
          Corporation or any ERISA Affiliate is entitled to benefits under any Plan other
          than continuation of health coverage as required by Section 4980B of the Code
          and any such former employee or retiree who is covered pursuant to the
          requirements of Section 4980B is paying for such coverage at the maximum rate
          payment for continuation coverage may be required. The Corporation and each
          ERISA Affiliate has complied in all respects with the requirements of the
Health           Insurance Portability and Accountability Act of 1996 with respect to
each Plan           that provides welfare benefits. The Corporation does not maintain any
plan which           is an “employee welfare benefit plan” (as such term is
defined under           Section (1) of ERISA) that has provided any “disqualified
benefit” (as           such term is defined in Section 4976(b) of the Code) with
respect to which an           excise tax could be imposed under Section 4976.  

- 14 -

		    (xiv)       Each
of the Corporation and its ERISA Affiliates has funded each Plan in           accordance
with the terms of such Plan through the date hereof, including the           payment of
applicable premiums on insurance contract funding a Plan, for           coverage provided
through the date hereof.  

		    (xv)       Except
as contemplated herein or required by law, the execution of this           Agreement and
the consummation of the transactions contemplated hereby, do not           constitute a
triggering event under any Plan, policy, arrangement, statement,           commitment or
agreement which (either alone or upon the occurrence of any           additional or
subsequent event) will result in any obligation of the Corporation           or any ERISA
Affiliate to make any payment (whether of severance pay, including,           and not
limited to, salary, related vacation pay, pension pay and other similar
          payments and costs, or otherwise) or to accelerate, vest or increase the amount
          of benefits payable to any employee or former employee or director of the
          Corporation or any ERISA Affiliate. No Plan or agreement provides for the
          payment of severance benefits upon the termination of any employee’s
          employment. No amounts paid or payable by Corporation will fail to be
deductible           for federal income tax purposes by reason of Section 280G of the
Code.  

		    (xvi)       The
balance sheets of the Corporation as of December 31, 2003, 2004 and 2005,
          properly and adequately reflect, in accordance with US GAAP consistently
applied           with prior periods, any and all liabilities and obligations of the
Corporation           and its ERISA Affiliates relating to any period ending on or prior
to the date           hereof to or in respect of current and former employees of the
Corporation or           any ERISA Affiliate or the Plans, for (A) unpaid compensation,
salaries, wages,           vacation pay, disability payments and other payroll items
(including, without           limitation, bonus, incentive or deferred compensation), (B)
unpaid           contributions, costs and expenses to or in respect of any Plans, and (C)
          severance or other termination benefits relating to, resulting from or arising
          in respect of any termination of employment occurring on or prior to the date
          hereof.  

		    (r)       Litigation.
Except for the matters set forth on Schedule 4(r), (A)           Neither the
Corporation nor any of the Acquired Assets, is a party or is subject           to, or to
the knowledge of the Corporation, threatened with, any suit, action,
          arbitration, administrative or other proceeding, either at law or in equity, or
          governmental investigation by or before any court, governmental department,
          commission, board, agency or instrumentality, domestic or foreign; (B) to the
          knowledge of the Corporation, there is no basis for any suit, action,
          arbitration, or administrative or other proceeding against the Corporation; (C)
          there is no judgment, decree, award or order outstanding against the
          Corporation; (D) the Corporation is not contemplating the institution by it of
          any suit, action, arbitration, administrative or other proceeding; and (E) to
          the knowledge of the Corporation, there has been no occurrence that may
          result in a claim for damages against the Corporation. The insurance carriers
of           the Corporation have agreed to defend and indemnify the Corporation against
any           loss resulting to the Corporation therefrom.

		    (s)       Suppliers
and Customers. Schedule 4(s) is a complete and accurate           list of the
names of all suppliers and customers of the Corporation which           respectively
contribute more than 5% of all sales and services to, and orders           and use of
services from, the Corporation (“Suppliers” and           “Customers,” respectively).
The relationships of the Corporation with           its Suppliers and Customers are good
commercial working relationships and no           Supplier or Customer of the Corporation
has canceled or otherwise terminated,           or, to the knowledge of the Corporation,
threatened to cancel or otherwise           terminate, its relationship with the
Corporation, or has during the last twelve           (12) months decreased materially,
or, to the knowledge of the Corporation,           threatened to decrease or limit
materially, its business with the Corporation.           No interruptions or shortages in
the supply of raw materials and other key           supplies are threatened or
anticipated. To the knowledge of the Corporation (i)           no new products have been
developed by others that would result in a material           loss of business to the
Corporation, render the Corporation’s products           obsolete, or otherwise
place the Corporation’s products at a competitive           disadvantage; and (ii)
the acquisition of the Acquired Assets by Buyer will not           adversely affect the
relationship of the Buyer, as successor to the Corporation,           with any such
Supplier or Customer.  

		    (t)       Conflicting
Interests. No director, officer or manager of the Corporation           (i) has any
pecuniary interest in any supplier or customer of the Corporation or           in any
other business enterprise with which the Corporation conducts business or           with
which the Corporation is in competition; (ii) is indebted to the           Corporation;
(iii) is a party to any transaction or agreement with the           Corporation (apart
from such Person’s status as a director, officer or           manager as such); or
(iv) has any business or other interest in conflict with           the interests of the
Corporation.  

		    (u)       Compliance
with Law and Regulations. The Corporation is in compliance           with, and has at
all times complied with, all requirements of U.S. Federal,           state, and local law
and, where applicable, their foreign equivalents, and all           requirements of all
governmental bodies or agencies having jurisdiction over it,           the conduct of its
business, the use of its properties and assets, and all           premises occupied by
it. Without limiting the foregoing,the Corporation           has paid all monies
to obtain, and has obtained and now holds, all licenses,           permits, certificates,
and authorizations needed or required for the conduct of           its business as
currently conducted and the current use of its properties and           the premises
occupied by it. The Corporation has properly filed all reports and           other
documents required to be filed with any Federal, state, local and foreign
          government or subdivision or agency thereof. The Corporation has not received
          any notice from any Federal, state or municipal authority or any insurance or
          inspection body that any of its properties, facilities, equipment, or business
          procedures or practices fails to comply with any applicable law, ordinance,
          regulation, building or zoning law, or requirement of any public authority or
          body. All licenses, permits, orders and approvals issued by any governmental
          body or agency currently in effect and pertaining to the Acquired Assets are
          listed on Schedule 4(u) and, except as noted on Schedule 4(u) none
          of the items so listed will lapse or expire as a result of the transactions
          contemplated hereby.  

		    (v)       Environmental
Matters.  

		    (i)       The
Corporation and to the knowledge of the Corporation, any predecessor of the
          Corporation is and at all times have been in compliance with all Environmental
          Laws (as hereinafter defined) governing their business, operations, properties
          and assets, which compliance includes, but is not limited to: (A) the

governmental authority,           employee, group or third party alleging that it is not
in such full compliance           or that it has investigatory or remedial obligations or
other liability pursuant           to Environmental Law. To the knowledge of the
Corporation, there are no           circumstances that may prevent or interfere with such
full compliance or give           rise to investigatory or remedial obligations or other
liabilities pursuant to           any Environmental Law in the future. All permits and
other governmental           authorizations currently held by the Corporation pursuant to

applicable Environmental Law due to its physical characteristics, including
          without limitation, a wetland or waterway, or land which is geologically

          or by virtue of a use restriction in connection with environmental remediation.

in           such a jurisdiction, the operations conducted by the Corporation at such
Leased           Property(ies) are not subject to any such law.

		    (x)       For
purposes of this Agreement:  

		    (A)       “Discharge” means

agents (collectively the “Seller Indemnified           Parties”) (each of whom
shall be a third party beneficiary hereof) from,           against and in respect of the
amount of any and all Buyer Deficiencies (as           hereinafter defined).  

		    (d)       Definition
of “Buyer Deficiencies”. As used in this Section 15,           “Buyer
Deficiencies” means any and all loss or damage incurred by the           Corporation
or the Stockholders resulting from:  

		    (i)       any
misrepresentation, breach of any representation or warranty, or any
          non-fulfillment of any representation, warranty, covenant or agreement on the
          part of the Buyer contained in Section 5 herein;  

		    (ii)       any
Assumed Liability;  

- 32 -

		    (iii)       any
liability or obligation arising from the conduct of the business by Buyer           after
the Closing Date to the extent that such liability or obligation would not           be
the result of any Corporation Deficiency set forth in subsection 15(b); or  

		    (iv)       any
and all actions, suits, proceedings, demands, assessments, penalties,
          liabilities, judgments, reasonable attorneys’ fees, costs, expenses and
          interest incident to any of the foregoing.  

		    (e)       Procedures
for Establishment of Deficiencies.  

		    (i)       In
the event that any claim shall be asserted against a party which, if           sustained,
would result in a Deficiency, the indemnified party, within a           reasonable time
after learning of such claim, shall notify the indemnifying           party of such
claim, and shall extend to the indemnifying party a reasonable           opportunity to
defend against such claim, at the indemnifying party’s sole           expense and
through legal counsel reasonably satisfactory to the indemnified           party,
provided that the indemnifying party proceeds in good faith,           expeditiously and
diligently. The indemnified party shall, at its option and           expense, have the
right to participate in any defense undertaken by the           indemnifying party with
legal counsel of its own selection. If the indemnifying           party, in the
reasonable judgment of the indemnified party, has failed to           prosecute such
defense in good faith in an expeditious and diligent manner, the           indemnified
party shall have the right to defend and/or settle such claim on           behalf of the
indemnifying party. No settlement or compromise of any claim which           may result
in a Deficiency may be made by the indemnifying party without the           prior written
consent of the indemnified party unless the proposed settlement is           solely a
monetary settlement and prior to such settlement or compromise the           indemnifying
party acknowledges in writing the indemnifying party obligation to           pay in full
the amount of the settlement and all associated expenses and the           indemnified
party is furnished with either (A) security reasonably satisfactory           to the
indemnified party that the indemnifying party will in fact pay such           amount and
expenses, or (B) a full release from the claimant in form and           substance
reasonably satisfactory to the indemnified party.  

		    (ii)       In
the event that the indemnified party asserts the existence of any Deficiency,
          the indemnified party shall give written notice to the indemnifying party of
the           nature and amount of the Deficiency asserted. The indemnified party shall
          reasonably cooperate with such actions as the indemnifying party may seek to
          take to mitigate the impact of any alleged breach. Such request shall not be
          deemed to constitute an admission of liability on the part of the indemnifying
          party. If the indemnifying party, within a period of fifteen (15) business days
          after the giving of such notice by the indemnified party, shall not give
written           notice to the indemnified party announcing its intention to contest
such           assertion of the indemnified party (such notice by the indemnifying party
being           hereinafter called the “Contest Notice”), such assertion of the
          indemnified party shall be deemed accepted and the amount of the Deficiency
          shall be deemed established. In the event, however, that a Contest Notice is
          given to the indemnified party within said 15-day period, then the contested
          assertion of a Deficiency may be established pursuant to the provisions of
          Section 19 herein.  

- 33 -

		    (iii)       The
indemnified and indemnifying parties may agree in writing, at any time, as           to
the existence and amount of a Deficiency, and, upon the execution of such
          agreement, such Deficiency shall be deemed established.  

		    (f)       Payment
of Deficiencies. Subject to the limitations set forth in           subsection (g),
the indemnifyingparty hereby agree to pay in cash the           amount of each
established Deficiency to the indemnified party within five (5)           business days
after the final establishment thereof. Any amounts not paid by the           indemnifying
party when due under this subsection 15(f) shall bear interest from           the due
date thereof until the date paid at a rate equal to 3% over the           “prime rate” as
published from time to time in The Wall Street           Journal.  

		    (g)       Limitation.  

		    (i)       With
the exception of (A) any Deficiencies resulting from any misrepresentation           or
breach of representation or warranty contained in subsections 4(b),           4(g),
4(w), 5(a) and 5(b) herein or (B) any claims of Knowing Misrepresentation           on
the part of any party to this Agreement, there shall be no liability for any
          Deficiencies resulting from any misrepresentation or breach of representation
or           warranty on the part of either the Corporation under Section 4 or Buyer
under           Section 5.  

		    (ii)       With
respect to Deficiencies resulting from any (A) misrepresentation or breach           of
representation or warranty contained in subsections 4(b), 4(g), 4(w),           5(a)
and 5(b) herein; or (B) any Knowing Misrepresentation, neither party shall           be
liable or otherwise responsible for that portion of any such Deficiencies           that
exceeds an amount equal to the value at the Closing Date of the Buyer           Shares
issuable pursuant to this Agreement. The Corporation, the Stockholders or           the
Managers, may satisfy and discharge such liability by tendering back to the
          Buyer the Buyer Shares received by them pursuant to this Agreement, such Buyer
          Shares being deemed to have the value of such Buyer Shares at the Closing Date.  

		    (iii)       Notwithstanding
any of the foregoing, any party to this Agreement shall have           unlimited recourse
against any other party that has committed any Knowing           Misrepresentation.  

    16.       Board
Observer. As of Closing, and for so long as the Corporation           continues to
hold, or in the event that following distribution of Buyer Shares           by the
Corporation to the Stockholders the Stockholders continue to hold, in the
          aggregate, Buyer Shares in an amount equal to 7.1% of the outstanding capital
          stock of Buyer, the Representative shall be entitled to designate one
individual           (the “Observer”) to attend and observe any regular or
special meeting           of the board of directors of the Buyer and shall be entitled to
receive all           information distributed to the board of directors of the Buyer at
the time of           the original distribution of such information; provided, however,
that the           Observer shall agree to hold in confidence and trust and to act in a
fiduciary           manner with respect to all information so provided and to be bound by
the           Buyer’s code of ethics, policies and procedures; and provided further,
that           the Buyer reserves the right to withhold any information and to exclude
the           Observer from any meeting or portion thereof for any reason if access to
such           information or attendance at such meeting could affect any evidentiary
privilege           between Buyer and its advisors or otherwise adversely affects Buyer.
The initial           Observer will be Craig Gomulka.  

- 34 -

    17.        Piggyback
Registration Rights. At any time after the Buyer Shares issued           to the
Corporation pursuant to this Agreement have been distributed to the
          Stockholders by the Corporation, and/or the Employees Shares have been vested
          and distributed to the Employees or their designees, if Buyer at any time
          proposes to register any of its securities under the Securities Act for sale to
          the public (except with respect to registration statements on Forms S-4,
          F-4 or S-8 or another form not available for registering the Buyer Shares to be
          issued under this Agreement for sale to the public), each such time it will
give           written notice of its intention to do so to the Representative who will
provide           notice of the same to all persons who received Buyer Shares hereunder.
Upon the           written request of any of such holders made to the Representative
within fifteen           (15) days after receipt of such notice, and forwarded to Buyer
within five (5)           days thereafter, Buyer will, subject to the limits contained in
this Section 17,           use its best efforts to cause all such Buyer Shares then held
by such holders           which are sought to be registered hereunder, to be registered
under the           Securities Act and qualified for sale under any state blue sky law,
all to the           extent requisite to permit such sale or other disposition by such
holders of the           Buyer Shares so registered; provided, however, that if Buyer is
advised in           writing in good faith by any managing underwriter of the Buyer’s
securities           being offered in a public offering pursuant to such registration
statement that           the amount to be sold by Persons other than the Buyer
(collectively,           “Selling Security Holders”) is greater than the amount
which can be           offered without adversely affecting the offering, Buyer may reduce
the amount           offered for the accounts of all Selling Security Holders (including
the           Stockholders and other holders of Buyer Shares hereunder) who have a
          contractual, incidental “piggy back” right to include such securities
          in a registration statement to a number deemed satisfactory by such managing
          underwriter; provided, however, that no reduction shall be made
in           the amount of Buyer Shares offered for the accounts of the Stockholders and
          other holders hereunder unless such reduction is imposed pro rata with respect
          to all securities whose holders have or may hereafter acquire a contractual,
          incidental “piggy back” right to include such securities in the
          registration statement as to which inclusion has been requested pursuant to
such           right. Notwithstanding the foregoing, Buyer’s obligation to register
the           Buyer Shares under this Section 17 shall terminate at such time when the
holders           thereof may sell all of such Buyer Shares, without limitation or
restriction, as           to timing and amount, pursuant to Rule 144 of the
Securities Act.  

    18.       Further
Assurances. Buyer, the Corporation and Stockholders agree to           execute and
deliver all such other instruments and take all such other action as           any party
may reasonably request from time to time, after the date hereof and           without
payment of further consideration, in order to effectuate the           transactions
provided for herein. The parties shall cooperate fully with each           other and with
their respective counsel and accountants in connection with any           steps required
to be taken as part of their respective obligations under this           Agreement,
including, without limitation, the preparation of financial           statements and
preparation and filing of Tax Returns.

    19.       Dispute
Resolution.  

		    (a)       In
the event of a dispute between the parties, including indemnification claims
          pursuant to Section 15, the parties shall first promptly attempt in good faith
          to resolve such dispute for a period of not less than thirty (30) calendar
days.           If such good faith efforts are not successful within such 30-day period,
at any           time thereafter, any party may give the other written notice of a
dispute (a           “Dispute Notice”), the parties shall attempt in good faith
to agree to           the appointment of an independent mediator (a “Mediator”)
to assist           the parties in resolving the dispute. Should the parties agree to a
Mediator,           the matter shall be referred to such Mediator for resolution in
accordance with           the usual practices and procedures of such Mediator; provided,
however, that no           party shall have an obligation to participate in any mediation
after a date           which is thirty (30) calendar days after the applicable Dispute
Notice was           served. The parties shall cooperate with the Mediator and shall
provide any           relevant information requested by the Mediator. If the parties
cannot agree on           the selection of a Mediator within twenty (20) calendar days
after delivery of           the Dispute Notice, or if the dispute is not resolved by the
Mediator as           provided herein, then the dispute shall be determined by
arbitration in           accordance with the provisions of subsection 19(b) hereunder.  

		    (b)       Any
dispute which is not settled or otherwise resolved through the provisions of
          subsection 19(a) above shall be determined by arbitration in Philadelphia,
          Pennsylvania by a single arbitrator in accordance with the rules of the
American           Arbitration Association (“AAA”) or any other rules agreed
upon by the           parties, except that (i) every person named on any list of
potential arbitrators           shall be a neutral and impartial lawyer with excellent
academic and professional           credentials who has practiced law for at least
fifteen (15) years, specializing           in either general commercial litigation or
general corporate and commercial           matters, and who has had experience, and is
generally available to serve, as an           arbitrator, and (ii) each party shall be
entitled to strike on a peremptory           basis, for any reason or no reason, any or
all of the names of potential           arbitrators on any list submitted to the party by
the AAA as well as any person           selected by the AAA to serve as an arbitrator by
administrative appointment. In           the event the parties cannot agree on the
selection of the arbitrator from the           one or more lists submitted by the AAA
within thirty (30) calendar days after           the AAA transmits to the parties its
first list of potential arbitrators, AAA           shall nominate three Persons who meet
the criteria set forth herein. Each party           shall be entitled to strike one of
such three nominees on a peremptory basis           within five (5) calendar days after
its receipt of such list of nominees,           indicating its order of preference with
respect to the remaining nominees. If           two of such nominees have been stricken
by the parties to the dispute, the           unstricken nominee shall be the arbitrator.
Otherwise, the selection of the           arbitrator shall be made by the AAA from the
remaining nominees in accordance           with the parties’ mutual order of
preference, or by random selection in the           absence of a mutual order of
preference. The arbitrator shall base his or her           award on the terms of this
Agreement, on applicable law and judicial precedent,           shall include in such
award the findings of fact and conclusions of law upon           which the award is based
and shall not grant any remedy or relief that a court           could not grant under
applicable law. The arbitration shall be governed by the           substantive laws of
the Commonwealth of Pennsylvania applicable to contracts           made and to be
performed therein, without regard to conflicts of laws rules.           Judgment on the
award rendered by the arbitrator(s) may be entered in any court           having
jurisdiction thereof.  

		    (c)       If
any party to a dispute fails to proceed with the dispute resolution           procedures
set forth in this Section 19 or unsuccessfully seeks to stay such           proceedings,
or fails to comply with any arbitration award, or is unsuccessful           in vacation
or modifying the award pursuant to a petition or application for           judicial
review, the other party shall be entitled to be awarded costs,           including
reasonable attorneys’ fees, paid or incurred by such other party           in
successfully compelling such proceedings or defending against the attempt to
          stay, vacate or modify such arbitration award and/or successfully defending or
          enforcing the award.

    20.       Representative.  

		    (a)       For
purposes of this Agreement, the “Representative” shall meanDon Jones.
All actions of the Representative shall be made personally by the
          Representative, and no Representative shall be permitted to assign or delegate
          its rights or duties, whether by operation of law or otherwise. In the event of
          the death, incapacity, incompetency, disability or resignation of the
          Representative, the Corporation, or if dissolved at such time, the remaining
          Stockholders shall elect a new Representative who shall have full authority to
          take all actions required or permitted to be taken by the Representative under
          this Agreement. Prompt written notice of the election of a substitute
          Representative shall be provided to Buyer by the substitute Representative so
          elected, and Buyer shall be entitled to rely on the authority of any substitute
          Representative elected pursuant to the procedures set forth in this subsection
          20(a).  

		    (b)       In
addition to, and not in substitution of, the provisions set forth in           subsection
20(a), the Corporation and each of the Stockholders hereby authorizes           the
Representative to take any and all actions (or not to take any or all           actions),
and/or to prepare, determine, calculate, negotiate, execute and           deliver any and
all agreements, notices, consents, determinations, documents and           other
instruments, which the Corporation or any such Stockholder (or the
          Representative on behalf of the Corporation of any such Stockholder) is
required           or permitted to take, prepare, determine, calculate, negotiate,
execute and/or           deliver under or pursuant to this Agreement and/or as
contemplated by this           Agreement, all in the name of and on the behalf of the
Corporation or any such           Stockholder, including, but not limited to, the making
and execution of any           amendments to this Agreement, the giving and receipt of
any notices or consents           pursuant hereto, the execution of any and all documents
required to be executed           in order to complete Closing hereunder or appropriate
or incidental to so           complete Closing hereunder, to calculate, determine,
negotiate and give notice           of or otherwise with respect to any adjustment to any
issuance of Buyer Shares           to be made pursuant to this Agreement, to accept
service of process in           connection with any claim related to this Agreement and
to prosecute, defend or           settle in the Representative’s discretion all
indemnification disputes           (including hiring of counsel and other litigation
assistance). From and after           the Closing, Buyer shall be entitled to deal
exclusively with the Representative           with respect to any matter arising under
this Agreement. Such appointment shall,           to the fullest extent permitted by law,
survive the dissolution or liquidation           of the Corporation, the death,
disability, incapacity, or incompetency of any           Stockholder.  

    21.       Miscellaneous.  

		    (a)       Indulgences,
Etc. Neither the failure nor any delay on the part of any           party to exercise
any right, remedy, power or privilege under this Agreement           shall operate as a
waiver thereof, nor shall any single or partial exercise of           any right, remedy,
power or privilege preclude any other or further exercise of           the same or of any
other right, remedy, power or privilege, nor shall any waiver           of any right,
remedy, power or privilege with respect to any occurrence be           construed as a
waiver of such right, remedy, power or privilege with respect to           any other
occurrence. No waiver shall be effective unless it is in writing and           is signed
by the party asserted to have granted such waiver.  

- 37 -

		    (b)       Controlling
Law. This Agreement and all questions relating to its           validity,
interpretation, performance and enforcement (including, without           limitation,
provisions concerning limitations of actions), shall be governed by           and
construed in accordance with the laws of the Commonwealth of Pennsylvania,
          notwithstanding any conflict-of-laws doctrines of such state or other
          jurisdiction to the contrary, and without the aid of any canon, custom or rule
          of law requiring construction against the draftsman.  

		    (c)       Confidentiality;
Public Announcements. From and after the Closing, the           Corporation and the
Stockholders will treat and hold as such all of the           Confidential Information,
refrain from using any of the Confidential Information           except in connection
with this Agreement, and deliver promptly to the Buyer or           destroy, at the
request and option of the Buyer, all tangible embodiments (and           all copies) of
the Confidential Information which are within the Corporation or           the
Stockholders’ possession. In the event that the Corporation or any of           the
Stockholders, as the case may be, is requested or required (by oral question           or
request for information or documents in any legal proceeding, interrogatory,
          subpoena, civil investigative demand, or similar process) to disclose any
          Confidential Information, the Corporation or any such Stockholder shall notify
          the Buyer promptly of the request or requirement so that the Buyer may seek an
          appropriate protective order or waive compliance with the provisions of this
          subsection 20(c). If, in the absence of a protective order or the receipt
          of a waiver hereunder, the Corporation or any such Stockholder, as the case may
          be, is, on the advice of counsel, compelled to disclose any Confidential
          Information to any tribunal or else stand liable for contempt, the Corporation
          or any such Stockholder may disclose the Confidential Information to the
          tribunal; provided, however, that such Stockholder shall use reasonable best
          efforts to obtain, at the request of the Buyer at its sole expense, an order or
          other assurance that confidential treatment will be accorded to such portion of
          the Confidential Information required to be disclosed as the Buyer shall
          designate. “Confidential Information” shall mean confidential
          information and trade secrets of the Corporation, including without limitation,
          (i) the identity, lists or descriptions of any customers, referral sources or
          organizations; (ii) financial statements, cost reports or other financial
          information; (iii) contracts proposals, or bidding information; (iv) business
          plans, product roadmaps and training operations, methods and manuals; (v)
          personnel records; and (vi) fee structure and management systems, policies or
          procedures, including related forms and manuals and (vii) any data, software,
          reports, formulae, drawings, sketches and other information disclosed by the
          Corporation to any Stockholder and was identified as confidential or
proprietary           in connection with such disclosure. The Representative shall
consult with Buyer           and Buyer shall consult with the Representative before
issuing any press release           or otherwise making any public statements with
respect to this Agreement, the           transactions contemplated hereby and any
negotiations in connection therewith           and, except as may be required under
applicable law, as provided above, shall           not issue any such press release or
make any such public statement prior to such           consultation.  

		    (d)       No
Fractional Shares. No fractional shares may be issued in connection           with
this Agreement. Any number of Buyer Shares which may be issued pursuant to           any
provision of this Agreement shall be rounded to the nearest whole number.

		    (g)        Exhibits
and Schedules. All Exhibits and Schedules attached hereto are           hereby
incorporated by reference into, and made a part of, this Agreement.  

		    (h)        Binding
Nature of Agreement. This Agreement shall be binding upon and           inure to the
benefit of the parties hereto and their respective successors and           assigns,
except that the Corporation and the Stockholders may not assign or           transfer
their rights or obligations under this Agreement other than by           operation of law
without the prior written consent of Buyer (which consent shall           not be
unreasonably delayed, conditioned or withheld).  

		    (i)        Execution
in Counterparts. This Agreement may be executed in any number           of
counterparts, each of which shall be deemed to be an original as against any
          party whose signature appears thereon, and all of which shall together
          constitute one and the same instrument.  

		    (j)        Provisions
Separable. The provisions of this Agreement are independent of           and
separable from each other, and no provision shall be affected or rendered
          invalid or unenforceable by virtue of the fact that for any reason any other or
          others of them may be invalid or unenforceable in whole or in part. However, in
          the event any provision of this Agreement shall be held or declared invalid or
          unenforceable in whole or in part by any court of competent jurisdiction, such
          court shall (to the full extent permitted by applicable law) revise or reform
          the Agreement, and/or take such other action as may be necessary or
appropriate,           with respect to such invalid or unenforceable provision so as to
carry out the           intent of the parties as expressed in this Agreement in a manner
that is not so           invalid or unenforceable.  

		    (k)        Entire
Agreement. This Agreement contains the entire understanding           between the
parties hereto with respect to the subject matter hereof, and           supersedes all
prior and contemporaneous agreements and understandings,           inducements or
conditions, express or implied, oral or written.  

		    (l)        Section
Headings. The Section headings in this Agreement are for           convenience only;
they form no part of this Agreement and shall not affect its           interpretation.  

		    (m)        Gender
and Number. Words used herein, regardless of the number and gender
          specifically used, shall be deemed and construed to include any other number,
          singular or plural, and any other gender, masculine, feminine or neuter, as the
          context indicates is appropriate.  

- 40 -

		    (n)        Number
of Days. In computing the number of days for purposes of this           Agreement,
all days shall be counted, including Saturdays, Sundays and Holidays;           provided,
however, that if the final day of any time period falls on a Saturday,           Sunday
or Holiday; then the final day shall be deemed to be the next day which           is not
a Saturday, Sunday or such Holiday. For purposes of this Section,           “Holiday” shall
mean a day, other than a Saturday or Sunday, on which           national banks are or may
elect to be closed.
