[For the Class 2-A-1, 2-A-2, 2-A-3 and 2-A-4 Certificates only] [The Record Date applicable to each Distribution Date is the Business Day immediately preceding the related Distribution Date.] [For the Classes other than the Class 2-A-1, 2-A-2, 2-A-3 and 2-A-4 Certificates only] [The Record Date applicable to each Distribution Date is the last Business Day of the month immediately preceding the month in which the related Distribution Date occurs.]

Distributions on this Certificate shall be made by wire transfer of immediately available funds to the account of the Holder hereof at a bank or other entity having appropriate facilities therefor, if such Certificateholder shall have so notified the Trust Administrator in writing at least five Business Days prior to the related Record Date and such Certificateholder shall satisfy the conditions to receive such form of payment set forth in the Agreement, or, if not, by check mailed by first class mail to the address of such Certificateholder appearing in the Certificate Register. The final distribution on each Certificate will be made in like manner, but only upon presentment and surrender of such Certificate at the Corporate Trust Office of the Trust Administrator or such other location specified in the notice to Certificateholders of such final distribution.

The Agreement permits, with certain exceptions therein provided, the amendment thereof and the modification of the rights and obligations of the Trust Administrator and the rights of the Certificateholders under the Agreement at any time by the Transferor, the Depositor, the Master Servicer, the Trust Administrator, the Custodian and the Trustee with the consent of the Holders of Certificates affected by such amendment evidencing the requisite Percentage Interest, as provided in the 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 therefor 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, wi thout 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 of the Trust Administrator upon surrender of this Certificate for registration of transfer at the offices that the Trust Administrator designates for such purposes, accompanied by a written instrument of transfer in form satisfactory to the Trust Administrator and the Certificate Registrar 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 and evidencing the same aggregate Percentage Interest in the Trust Fund will be issued to the designated transferee or transferees.

The Certificates are issuable only as registered Certificates without coupons in denominations 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 and 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, but the Trust Administrator may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Depositor, the Master Servicer, the Trust Administrator and the Trustee and any agent of the Depositor, the Master Servicer, the Trust Administrator or the Trustee may treat the Person in whose name this Certificate is registered as the owner hereof for all purposes, and neither the Depositor, the Master Servicer, the Trust Administrator, the Trustee, nor any such agent shall be affected by any notice to the contrary.

On any Distribution Date on which the Pool Principal Balance is less than 10% of the aggregate Cut-off Date Principal Balances of the Mortgage Loans, the Master Servicer will have the option to repurchase, in whole, from the Trust Fund all remaining Mortgage Loans and all property acquired in respect of the Mortgage Loans at a purchase price determined as provided in the Agreement. In the event that no such optional termination occurs, the obligations and responsibilities created by the Agreement will terminate upon the later of the maturity or other liquidation (or any advance with respect thereto) of the last Mortgage Loan remaining in the Trust Fund or the disposition of all property in respect thereof and the distribution to Certificateholders of all amounts required to be distributed pursuant to the Agreement. In no event, however, will the trust created by the Agreement continue b eyond the expiration of 21 years from the death of the last survivor of the descendants living at the date of the Agreement of a certain person named in the Agreement.

STATE OF

ss.:

COUNTY OF

)

The undersigned, being first duly sworn, deposes and says as follows:

The undersigned is an officer of _______, the proposed Transferee of an Ownership Interest in a Class A-[_]R Certificate (the “Certificate”) issued pursuant to the Pooling and Servicing Agreement dated as of March 1, 2006 (the “Agreement”) among Mortgage Asset Securitization Transactions, Inc., as depositor, UBS Real Estate Securities Inc., as transferor (the “Transferor”), Wells Fargo Bank, N.A., as master servicer (in such capacity, the “Master Servicer”), as trust administrator (in such capacity, the “Trust Administrator”), and as custodian (in such capacity, the “Custodian”), and The Bank of New York, as trustee (the “Trustee”). Capitalized terms used, but not defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such terms in the Agreement . The Transferee has authorized the undersigned to make this affidavit on behalf of the Transferee.

The Transferee is, as of the date hereof, and will be, as of the date of the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership Interest in the Certificate either (i) for its own account or (ii) as nominee, trustee or agent for another Person and has attached hereto an affidavit from such Person in substantially the same form as this affidavit. The Transferee has no knowledge that any such affidavit is false.

The Transferee has been advised of, and understands that (i) a tax will be imposed on Transfers of the Certificate to Persons that are Disqualified Organizations; (ii) such tax will be imposed on the transferor, or, if such Transfer is through an agent (which includes a broker, nominee or middleman) for a Person that is a Disqualified Organization, on the agent; and (iii) the Person otherwise liable for the tax shall be relieved of liability for the tax if the subsequent Transferee furnished to such Person an affidavit that such subsequent Transferee is not a Disqualified Organization and, at the time of Transfer, such Person does not have actual knowledge that the affidavit is false.

The Transferee has been advised of, and understands that a tax will be imposed on a “pass-through entity” holding the Certificate if at any time during the taxable year of the pass-through entity a Person that is a Disqualified Organization is the record holder of an interest in such entity. The Transferee understands that such tax will not be imposed for any period with respect to which the record holder furnishes to the pass-through entity an affidavit that such record holder is not a Disqualified Organization and the pass-through entity does not have actual knowledge that such affidavit is false; provided, that a pass-through entity which is an “electing large partnership” under the Code will be subject to tax in all events. (For this purpose, a “pass-through entity” includes a regulated investment company, a real estate investment trust or common trust fund, a partnership, trust or estate, and certain cooperatives and, except as may be provided in Treasury Regulations, persons holding interests in pass-through entities as a nominee for another Person.) The Transferee further understands that it may incur tax liabilities with respect to the holding of the Certificate in excess of cash flows generated thereby.

The Transferee has reviewed the provisions of Section 5.02(c) of the Agreement (attached hereto as Exhibit 2 and incorporated herein by reference) and understands the legal consequences of the acquisition of an Ownership Interest in the Certificate including, without limitation, the restrictions on subsequent Transfers and the provisions regarding voiding the Transfer and mandatory sales. The Transferee expressly agrees to be bound by and to abide by the provisions of Section 5.02(c) of the Agreement and the restrictions noted on the face of the Certificate. The Transferee understands and agrees that any breach of any of the representations included herein shall render the Transfer to the Transferee contemplated hereby null and void.

The Transferee agrees to require a Transfer Affidavit from any Person to whom the Transferee attempts to Transfer its Ownership Interest in the Certificate, and in connection with any Transfer by a Person for whom the Transferee is acting as nominee, trustee or agent, and the Transferee will not Transfer its Ownership Interest or cause any Ownership Interest to be Transferred to any Person that the Transferee knows is not a Permitted Transferee. In connection with any such Transfer by the Transferee, the Transferee agrees to deliver to the Trust Administrator a certificate substantially in the form set forth as Exhibit I to the Agreement (a “Transferor Certificate”) to the effect that such Transferee has no actual knowledge that the Person to which the Transfer is to be made is not a Permitted Transferee.

The Transferee does not have the intention to impede the assessment or collection of any tax legally required to be paid with respect to the Certificate. The Transferee historically has paid its debts as they have become due and intends to do so in the future. The Transferee understands that the taxable income and tax liability with respect to this Certificate will exceed distributions with respect to the Certificate in some or all periods and intends to pay all taxes with respect to the Certificate as they become due.

The Transferee’s taxpayer identification number is __________.

The Transferee is a U.S. Person as defined in Code Section 7701(a)(30) or is not a U.S. Person and has furnished the Transferor and the Trust Administrator with a duly completed Internal Revenue Service Form W-8ECI or any applicable successor form.

10.

The Transferee is aware that the Certificate may be a “noneconomic residual interest” within the meaning of proposed Treasury regulations promulgated pursuant to the Code and that the transferor of a noneconomic residual interest will remain liable for any taxes due with respect to the income on such residual interest, unless no significant purpose of the transfer was to impede the assessment or collection of tax.

11.

The Transferee will not cause income with respect to the Certificate to be attributable to a foreign permanent establishment or fixed base, within the meaning of an applicable income tax treaty, of the Transferee or any other U.S. Person.

12.

Check one of the following paragraphs:

□ The present value of the anticipated tax liabilities associated with holding the Certificate, as applicable, does not exceed the sum of:

(i)

the present value of any consideration given to the Transferee to acquire such Certificate;

(ii)

the present value of the expected future distributions on such Certificate; and

(iii)

the present value of the anticipated tax savings associated with holding such Certificate as the related REMIC generates losses.

For purposes of this calculation, (i) the Transferee is assumed to pay tax at the highest rate currently specified in Section 11(b) of the Code (but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate specified in Section 11(b) of the Code if the Transferee has been subject to the alternative minimum tax under Section 55 of the Code in the preceding two years and will compute its taxable income in the current taxable year using the alternative minimum tax rate) and (ii) present values are computed using a discount rate equal to the short-term Federal rate prescribed by Section 1274(d) of the Code for the month of the transfer and the compounding period used by the Transferee.

□ The transfer of the Certificate complies with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

(i)

the Transferee is an “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to which income from the Certificate will only be taxed in the United States;

(ii)

at the time of the transfer, and at the close of the Transferee’s two fiscal years preceding the year of the transfer, the Transferee had gross assets for financial reporting purposes (excluding any obligation of a person related to the Transferee within the meaning of U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100 million and net assets in excess of $10 million;

(iii)

the Transferee will transfer the Certificate only to another “eligible corporation,” as defined in U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), in a transaction that satisfies the requirements of U.S. Treasury Regulations Sections 1.860E-1(c)(4)(i), (ii) and (iii) and Section 1.860E-1(c)(5); and

(iv)

the Transferee determined the consideration paid to it to acquire the Certificate based on reasonable market assumptions (including, but not limited to, borrowing and investment rates, prepayment and loss assumptions, expense and reinvestment assumptions, tax rates and other factors specific to the Transferee) that it has determined in good faith.

□ None of the above.

13.

The Transferee is either: (i) not an employee benefit plan or other retirement arrangement subject to Section 406 of ERISA and/or Section 4975 of the Code, or a person acting for, on behalf of or with the assets of, any such plan or arrangement, (ii) if the purchaser is an insurance company, the purchaser is an insurance company which is purchasing such Certificate with funds contained in an “insurance company general account” (as such term is defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 (“PTCE 95-60”)) and the purchase and holding of such Certificate is covered under Sections I and III of PTCE 95-60, or (iii) the Transferee has delivered to the Trust Administrator an Opinion of Counsel satisfactory to the Trust Administrator to the effect that the purchase or holding of such Certificate will not result in prohibi ted transactions under Section 406 of ERISA and/or Section 4975 of the Code and will not subject the Trustee, the Transferor, the Depositor, the Master Servicer or the Trust Administrator to any obligation in addition to those undertaken in the Agreement, which Opinion of Counsel shall not be an expense of such parties or the Trust Fund.

EXHIBIT 2
to EXHIBIT I

Section 5.02(c) of the Agreement

Each Person who has or who acquires any Ownership Interest in a Residual Certificate shall be deemed by the acceptance or acquisition of such Ownership Interest to have agreed to be bound by the following provisions, and the rights of each Person acquiring any Ownership Interest in a Residual Certificate are expressly subject to the following provisions:

(i)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall be a Permitted Transferee and shall promptly notify the Trust Administrator of any change or impending change in its status as a Permitted Transferee.

(ii)

No Ownership Interest in a Residual Certificate may be registered on the Closing Date or thereafter transferred, and the Trust Administrator shall not register the Transfer of any Residual Certificate unless, in addition to the certificates required to be delivered to the Trust Administrator under subparagraph (b) above, the Trust Administrator shall have been furnished with an affidavit (a “Transfer Affidavit”) of the initial owner or the proposed transferee in the form attached hereto as Exhibit I.

(iii)

Each Person holding or acquiring any Ownership Interest in a Residual Certificate shall agree (A) to obtain a Transfer Affidavit from any other Person to whom such Person attempts to Transfer its Ownership Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from any Person for whom such Person is acting as nominee, trustee or agent in connection with any Transfer of a Residual Certificate and (C) not to Transfer its Ownership Interest in a Residual Certificate or to cause the Transfer of an Ownership Interest in a Residual Certificate to any other Person if it has actual knowledge that such Person is not a Permitted Transferee.

(iv)

Any attempted or purported Transfer of any Ownership Interest in a Residual Certificate in violation of the provisions of this Section 5.02(c) shall be absolutely null and void and shall vest no rights in the purported Transferee. If any purported transferee shall become a Holder of a Residual Certificate in violation of the provisions of this Section 5.02(c), then the last preceding Permitted Transferee shall be restored to all rights as Holder thereof retroactive to the date of registration of Transfer of such Residual Certificate. The Trust Administrator shall be under no liability to any Person for any registration of Transfer of a Residual Certificate that is in fact not permitted by Section 5.02(b) and this Section 5.02(c) or for making any payments due on such Certificate to the Holder thereof or taking any other action with respect to such Holder under the pr ovisions of this Agreement so long as the Transfer was registered after receipt of the related Transfer Affidavit, Transferor Certificate and either the Rule 144A Letter or the Investment Letter. The Trust Administrator shall be entitled but not obligated to recover from any Holder of a Residual Certificate that was in fact not a Permitted Transferee at the time it became a Holder or, at such subsequent time as it became other than a Permitted Transferee, all payments made on such Residual Certificate at and after either such time. Any such payments so recovered by the Trust Administrator shall be paid and delivered by the Trust Administrator to the last preceding Permitted Transferee of such Certificate.

(v)

The Depositor shall use its best efforts to make available, upon receipt of written request from the Trust Administrator, all information necessary to compute any tax imposed under Section 860E(e) of the Code as a result of a Transfer of an Ownership Interest in a Residual Certificate to any Holder who is not a Permitted Transferee described in clauses (i) through (iv) of the definition thereof.

The restrictions on Transfers of a Residual Certificate set forth in this Section 5.02(c) shall cease to apply (and the applicable portions of the legend on a Residual Certificate may be deleted) with respect to Transfers occurring after delivery to the Trust Administrator of an Opinion of Counsel, which Opinion of Counsel shall not be an expense of the Trust Fund, the Trustee, the Loan Seller, the Transferors, the Master Servicer or the Trust Administrator, to the effect that the elimination of such restrictions will not cause a REMIC hereunder to fail to qualify as a REMIC at any time that the Certificates are outstanding or result in the imposition of any tax on the Trust Fund, a Certificateholder or another Person. Each Person holding or acquiring any Ownership Interest in a Residual Certificate hereby consents to any amendment of this Agreement which, based on an Opinion of Counsel furnished to the Trust Administrator, is reasonably necessary (a) to ensure that the record ownership of, or any beneficial interest in, a Residual Certificate is not transferred, directly or indirectly, to a Person that is not a Permitted Transferee and (b) to provide for a means to compel the Transfer of a Residual Certificate which is held by a Person that is not a Permitted Transferee to a Holder that is a Permitted Transferee.
