          This Pooling and Servicing Agreement (this "AGREEMENT"), is dated as

of May 1, 2005, among CREDIT SUISSE FIRST BOSTON MORTGAGE SECURITIES CORP., as

Depositor, KEYCORP REAL ESTATE CAPITAL MARKETS, INC., as Master Servicer, J.E.

ROBERT COMPANY, INC., as Special Servicer and WELLS FARGO BANK, N.A., as

Trustee.

 

                             PRELIMINARY STATEMENT:

 

          The Depositor intends to sell commercial mortgage pass-through

certificates (collectively, the "CERTIFICATES"), to be issued under this

Agreement in multiple classes (each, a "CLASS"), which in the aggregate will

evidence the entire beneficial ownership interest in the trust fund (the "TRUST

FUND") to be created hereunder, the primary assets of which will be a pool of

multifamily and commercial mortgage loans listed on EXHIBIT B hereto and the

Swap Agreement (as defined herein). As provided herein, the Trustee shall elect

or shall cause an election to be made that each of the Upper-Tier REMIC, the

Lower-Tier REMIC and the Loan REMIC (each as defined herein) be treated for

federal income tax purposes as a "real estate mortgage investment conduit" (a

"REMIC"). The Excess Interest, the Excess Interest Distribution Account, the

Broker Strip Interest, the Excess Servicing Strip, the Swap Agreement and the

Floating Rate Account (each as defined herein) shall not be assets of any REMIC

but shall be treated as assets of the several grantor trusts described below.

The Class A-X and Class A-SP Certificates will represent undivided beneficial

interests in multiple "regular interests" in the Upper-Tier REMIC. Additionally,

the Trust shall not include any Junior Loan, any interest of any Junior Loan

Holder or any Junior Loan Custodial Account.

 

                                UPPER-TIER REMIC

 

          As provided herein, the Trustee shall elect or cause an election to be

made to treat the segregated pool of assets consisting of the Uncertificated

Lower-Tier Interests and the proceeds thereof as a REMIC for federal income tax

purposes, and such segregated pool of assets will be designated as the

"UPPER-TIER REMIC". The Classes of Certificates listed in the table following

the next succeeding paragraph will evidence "regular interests" in the

Upper-Tier REMIC created hereunder. The Class A-MFL Upper-Tier Interest will

constitute a "regular interest" in the Upper-Tier REMIC created hereunder. The

sole class of "residual interests" in the Upper-Tier REMIC, as well as the sole

class of "residual interests" in the Lower-Tier REMIC and the sole class of

"residual interests" in the Loan REMIC, will be evidenced by the Class R

Certificates.

          The following table sets forth the designation, the initial

Pass-Through Rate (as defined herein), and the aggregate initial principal

amount (the "ORIGINAL CLASS PRINCIPAL BALANCE") or notional balance ("ORIGINAL

CLASS NOTIONAL AMOUNT"), as applicable, for each Class of Certificates

evidencing the "regular interests" in the Upper-Tier REMIC and the Class A-MFL

Upper-Tier Interest:

                                   LOAN REMIC

 

          As provided herein, the Trustee shall elect or cause an election to be

made to treat the Tri-County Mall Loan (exclusive of any portion thereof

constituting part of the Excess Servicing Strip) and certain other related

assets subject to this Agreement as a REMIC for federal income tax purposes, and

such segregated pool of assets will be designated as the "LOAN REMIC". Two

separate Loan REMIC regular interests, constituting beneficial ownership

interests in the Loan REMIC (together, the "LOAN REMIC REGULAR INTERESTS"),

shall be issued on the Closing Date, and such Loan REMIC Regular Interests shall

be designated as "LOAN REMIC REGULAR INTEREST TM-1" and "LOAN REMIC REGULAR

INTEREST TM-2", respectively. Each Loan REMIC Regular Interest shall relate to

the Tri-County Mall Loan and any successor REO Loan with respect thereto. Each

Loan REMIC Regular Interest shall (i) accrue interest at the related per annum

rate described in the definition of "LOAN REMIC REMITTANCE RATE" and (ii) have

an initial Loan REMIC Principal Balance as of the Closing Date equal to: (A)

$149,000,000 in the case of Loan REMIC Regular Interest TM-1; and (B) $9,000,000

in the case of Loan REMIC Regular Interest TM-2. Neither of the Loan REMIC

Regular Interests will be certificated. The sole class of "residual interests"

in the Loan REMIC, as well as the sole class of "residual interests" in the

Lower-Tier REMIC and the sole class of "residual interests" in the Upper-Tier

REMIC, will be evidenced by the Class R Certificates.

 

          The Class R Certificates will not have principal amounts or notional

balances and will not bear interest.

 

          The parties intend that the portion of the Trust Fund representing the

Excess Interest, any amounts on deposit in the Collection Account representing

Excess Interest and the Excess Interest Distribution Account shall be treated as

a grantor trust under subpart E of Part I of subchapter J of Chapter 1 of

Subtitle A of the Code and that the Class V Certificates shall represent

undivided beneficial interests in the portion of the Trust Fund consisting of

the Excess Interest, any amounts on deposit in the Collection Account

representing Excess Interest and the Excess Interest Distribution Account.

 

          The parties intend that the portion of the Trust Fund representing the

Broker Strip Interest and any amounts on deposit in the Collection Account

representing the Broker Strip Interest shall be treated as a grantor trust under

subpart E of Part I of subchapter J of Chapter 1 of Subtitle A of the Code.

 

          The parties intend that the portion of the Trust Fund representing the

Excess Servicing Strip and any amounts on deposit in the Collection Account

representing the Excess Servicing Strip shall be treated as a grantor trust

under subpart E of Part I of subchapter J of Chapter 1 of Subtitle A of the

Code.

 

          The parties intend that the portion of the Trust Fund representing the

Class A-MFL Upper-Tier Interest (and distributions thereon), the Swap Agreement

(and payments by the Swap Counterparty thereunder) and the Floating Rate Account

shall be treated as a grantor trust under subpart E of Part I of subchapter J of

Chapter 1 of Subtitle A of the Code and that the Class A-MFL Certificates shall

represent undivided beneficial interests in the portion of the

 

                                        5

<Page>

 

Trust Fund consisting of the Class A-MFL Upper-Tier Interest, the Swap Agreement

and the Floating Rate Account.

 

          As of the close of business on the Cut-off Date (as defined herein),

the Loans had an aggregate principal balance, after application of all payments

of principal due on or before such date, whether or not received, equal to

$1,614,084,459.

Appraisal Reduction Event; and PROVIDED, FURTHER, that, if the related Mortgaged

Property has become an REO Property, then references to "Loan" above in this

definition shall include any successor REO Loan with respect to the subject

Loan.

 

          In the case of any CBA A Loan (or any successor REO Loan with respect

thereto), any Appraisal Reduction Amount will be calculated in respect of the

related CBA A/B Loan Pair (or any successor REO Loans with respect thereto), as

if it was a single Loan (or a single REO Loan), and any Appraisal Reduction

Amount shall first be allocated to the related CBA B Loan (or any successor REO

Loan with respect thereto), up to the outstanding principal balance of such

CBA B Loan (or REO Loan), and then any remaining portion of any such

otherwise removed from the Trust Fund.

 

          "APPRAISAL REDUCTION EVENT": With respect to any Loan, the earliest of

any grace period) occurs in respect of such Loan (except that with respect to a

Balloon Payment, such date may extend until the Loan becomes a Specially

Serviced Loan), (ii) the date on which a reduction in the amount of Monthly

Payments on such Loan, or a change in any other material economic term of such

Loan (other than an extension of the Maturity Date for a period of six months or

less), becomes effective as a result of a modification of such Loan by the

Special Servicer, (iii) 60 days after a receiver has been appointed and remains

undismissed for the Borrower or immediately after a receiver has been appointed

for the related Mortgaged Property, (iv) 30 days after a Borrower declares

bankruptcy, (v) 60 days after the Borrower has become the subject of a decree or

order for a bankruptcy proceeding that shall have remained in force undischarged

and unstayed, and (vi) immediately after such Loan becomes an REO Loan;

PROVIDED, HOWEVER, that if the Class TM Certificates are the only Class of

Principal Balance Certificates outstanding besides the Class A Sequential Pay

Certificates, then Appraisal Reduction Events will only occur with respect to

the Tri-County Mall Loan.

 

          "APPRAISED VALUE": With respect to any Mortgaged Property, the

appraised value thereof (as is) as determined by the most recent Appraisal

obtained or conducted, as appropriate, pursuant to this Agreement or obtained in

connection with the origination of the Loan; PROVIDED that, with respect to any

Mortgaged Property that secures a Loan with an outstanding principal balance

Mortgaged Property based on an internal valuation performed by the Special

Servicer.

renewed or extended through the date hereof and from time to time hereafter.

 

          "ASSUMED SCHEDULED PAYMENT": For any Due Period shall mean the

following:

 

          (a)   with respect to any Loan or Junior Loan that is delinquent in

     respect of its Balloon Payment (and, if applicable, any successor REO Loan

     with respect thereto as to which the Balloon Payment would have been past

     due), an amount equal to the sum of (i) the principal portion of the

     Monthly Payment that would have been due on such Loan or Junior Loan on the

     related Due Date based on the constant payment required by the related Note

     or the original amortization schedule thereof (as calculated with interest

     at the related Mortgage Rate), if applicable, assuming such Balloon Payment

     had not become due (and, if applicable, assuming the related Mortgaged

     Property had not become an REO Property), after giving effect to any

     modification of such Loan or Junior Loan, and (ii) one month's interest on

     the Stated Principal Balance of such Loan or Junior Loan (or, if

     applicable, any successor REO Loan with respect thereto) as of the end of

     such Due Period at the applicable Mortgage Rate. The amount of the Assumed

     Scheduled Payment for any A Loan or Junior Loan shall be calculated solely

     by reference to the terms of such A Loan or Junior Loan, as applicable (as

     modified in connection with any bankruptcy or similar proceeding involving

     the related Borrower or pursuant to a modification, waiver or amendment

     thereof granted or agreed to by the Master Servicer or the Special Servicer

     pursuant to the terms hereof) and without regard to the remittance

     provisions of the related Intercreditor Agreement; and

 

          (b)   any REO Loan that is not delinquent in respect of its Balloon

     Payment, an amount equal to the sum of (i) the principal portion of the
