MORTGAGE LOAN PURCHASE AGREEMENT

THIS MORTGAGE LOAN PURCHASE AGREEMENT (this "Agreement") is dated as

of November 8, 2006, between LASALLE BANK NATIONAL ASSOCIATION, as seller (the

"Seller"), and CITIGROUP COMMERCIAL MORTGAGE SECURITIES INC. ("CCMSI"), as

purchaser (the "Purchaser").

The Seller intends to sell, and the Purchaser intends to purchase,

certain multifamily, commercial and/or manufactured housing community mortgage

loans (the "Mortgage Loans") identified on the schedule (the "Mortgage Loan

Schedule") annexed hereto as "Annex A". The Purchaser intends to deposit the

Mortgage Loans, along with certain other mortgage loans (the "Other Mortgage

Loans"), into a trust fund (the "Trust Fund"), the beneficial ownership of which

will be evidenced by multiple classes (each, a "Class") of mortgage pass-through

certificates (the "Certificates"). One or more "real estate mortgage investment

conduit" ("REMIC") elections will be made with respect to most of the Trust

Fund. The Trust Fund will be created and the Certificates will be issued

pursuant to a pooling and servicing agreement (the "Pooling and Servicing

Agreement"), to be dated as of November 1, 2006, among CCMSI, as depositor,

Midland Loan Services, Inc. and Wachovia Bank, National Association, as master

servicers (each a "Master Servicer" and, together, the "Master Servicers"), LNR

Partners, Inc., as special servicer (the "Special Servicer"), Wells Fargo Bank,

National Association, as trustee (the "Trustee") and LaSalle Bank National

Association, as certificate administrator (the "Certificate Administrator").

Capitalized terms used herein (including the schedules attached hereto) but not

defined herein (or in such schedules) have the respective meanings set forth in

the Pooling and Servicing Agreement.

CCMSI intends to sell certain Classes of the Certificates (the

"Publicly Offered Certificates") to Citigroup Global Markets Inc. ("CGMI"),

LaSalle Financial Services, Inc., PNC Capital Markets LLC and Banc of America

Securities LLC (collectively, the "Dealers"), pursuant to an underwriting

agreement dated as of the date hereof (the "Underwriting Agreement"), between

CCMSI and the Dealers. The Publicly Offered Certificates are more particularly

described in a prospectus supplement dated November 8, 2006 (the "Prospectus

Supplement") and the accompanying base prospectus dated June 8, 2006 (the "Base

Prospectus" and, together with the Prospectus Supplement, the "Prospectus").

CCMSI further intends to sell the remaining Classes of the

Certificates (the "Privately Offered Certificates") to CGMI, pursuant to a

certificate purchase agreement dated as of the date hereof (the "Certificate

Purchase Agreement"), between CCMSI and CGMI. The Privately Offered Certificates

are more particularly described in an offering memorandum dated November 8, 2006

(the "Memorandum").

Certain Classes of the Certificates will be assigned ratings by

Moody's Investors Service, Inc. and/or Fitch, Inc. (together, the "Rating

Agencies").

In connection with its sale of the Mortgage Loans, the Seller shall

enter into an indemnification agreement dated as of the date hereof (the

"Indemnification Agreement"), between the Seller, CCMSI and the Dealers.

Now, therefore, in consideration of the premises and the mutual

agreements set forth herein, the parties agree as follows:

SECTION 1. Agreement to Purchase.

The Seller agrees to sell, and the Purchaser agrees to purchase, the

Mortgage Loans identified on the Mortgage Loan Schedule. The Mortgage Loan

Schedule may be amended to reflect the actual Mortgage Loans delivered to the

Purchaser pursuant to the terms hereof. The Mortgage Loans are expected to have

an aggregate principal balance as of the close of business on the Cut-off Date

(the "Seller Mortgage Loan Balance") of $1,052,893,575 (subject to a variance of

plus or minus 5.0%), after giving effect to any payments due on or before such

date, whether or not such payments are received. The Seller Mortgage Loan

Balance, together with the aggregate principal balance of the Other Mortgage

Loans as of the Cut-off Date (after giving effect to any payments due on or

before such date whether or not such payments are received), is expected to

equal an aggregate principal balance (the "Cut-off Date Pool Balance") of

$2,238,772,692 (subject to a variance of plus or minus 5.0%). The purchase and

sale of the Mortgage Loans shall take place on November 21, 2006 or such other

date as shall be mutually acceptable to the parties to this Agreement (the

"Closing Date"). The consideration (the "Aggregate Purchase Price") for the

Mortgage Loans shall consist of a cash amount, payable in immediately available

funds, as reflected on the settlement statement agreed to by the Seller and the

Purchaser, which amount shall include interest accrued on the Seller Mortgage

Loan Balance for the period from and including the Cut-off Date up to but not

including the Closing Date. (exclusive, in the case of any Mortgage Loan with

its first due date in January 2007, of one month's interest at the related

Mortgage Rate).

The Aggregate Purchase Price shall be paid to the Seller or its

designee by wire transfer in immediately available funds on the Closing Date.

SECTION 2. Conveyance of Mortgage Loans.

(a) Effective as of the Closing Date, subject only to receipt by the

Seller of the Aggregate Purchase Price and satisfaction or waiver of the other

conditions to closing that are for the benefit of the Seller, the Seller does

hereby sell, transfer, assign, set over and otherwise convey to the Purchaser,

without recourse (except as set forth in this Agreement), all the right, title

and interest of the Seller in and to the Mortgage Loans identified on the

Mortgage Loan Schedule as of such date, on a servicing-released basis, together

with all of the Seller's right, title and interest in and to the proceeds of any

related title, hazard, primary mortgage or other insurance and any escrow,

reserve or comparable accounts related to the Mortgage Loans, subject, in the

case of any Mortgage Loan that is part of a Loan Combination, to the rights of

the holder(s) of any other mortgage loan(s) in the related Loan Combination in

such proceeds and reserve or comparable accounts, and further subject to the

understanding that the Seller will sell certain servicing rights to the

applicable Master Servicer pursuant to that certain Servicing Rights Purchase

Agreement, dated as of the Closing Date, between such Master Servicer and the

Seller, and may require that a particular primary servicer remain in place with

respect to any or all of the Mortgage Loans.

2

(b) The Purchaser or its assignee shall be entitled to receive all

scheduled payments of principal and interest due after the Cut-off Date, and all

other recoveries of principal and interest collected after the Cut-off Date

(other than in respect of principal and interest on the Mortgage Loans due on or

before the Cut-off Date). All scheduled payments of principal and interest due

on or before the Cut-off Date but collected after the Cut-off Date, and

recoveries of principal and interest collected on or before the Cut-off Date

(only in respect of principal and interest on the Mortgage Loans due on or

before the Cut-off Date and principal prepayments thereon), shall belong to, and

shall be promptly remitted to, the Seller.

(c) No later than the Closing Date, the Seller shall, on behalf of the

Purchaser, deliver or cause to be delivered to the Trustee (with, except in the

case of an Ala Moana Portfolio Trust Mortgage Loan, a copy to the applicable

Master Servicer and the Special Servicer within ten (10) Business Days after the

Closing Date) the documents and instruments specified below under clauses (i),

(ii), (vii), (ix)(A) and (xi)(D) and shall, not later than the date that is 30

days after the Closing Date, deliver or cause to be delivered to the Trustee

(with a copy to the applicable Master Servicer) the remaining documents and

Trust Mortgage Loan shall contain the following documents:

(including any A-Note Trust Mortgage Loan), the original executed Mortgage

also on behalf of the related B-Noteholder(s)), or in blank;

(v) an original assignment of all unrecorded documents relating

2006-C5" (and, in the case of an A/B Loan Combination, also on behalf of

the related B-Noteholder(s)), or in blank;

(vi) originals or copies of any consolidation, assumption,

substitution and modification agreements in those instances where the terms

or provisions of the Mortgage or Mortgage Note have been consolidated or

modified or the subject Serviced Mortgage Loan has been assumed or

consolidated;

(vii) the original or a copy of the policy or certificate of

lender's title insurance or, if such policy has not been issued or located,

an original or copy of an irrevocable, binding commitment (which may be a

pro forma policy or specimen version of, or a marked commitment for, the

policy that has been executed by an authorized representative of the title

company or an agreement to provide the same pursuant to binding escrow

instructions executed by an authorized representative of the title company)

to issue such title insurance policy;

(viii) any filed copies (bearing evidence of filing) or other

evidence of filing reasonably satisfactory to the Purchaser of any prior

UCC Financing Statements in favor of the originator of the subject Serviced

Mortgage Loan or in favor of any assignee prior to the Trustee (but only to

the extent the Seller had possession of such UCC Financing Statements when

it was to deliver the subject Mortgage File on or prior to the Closing

Date), unless not yet returned by the applicable filing office; and, if

there is an effective UCC Financing Statement in favor of the Seller on

record with the applicable public office for UCC Financing Statements, an

original UCC Financing Statement assignment, in form suitable for filing in

favor of "Wells Fargo Bank, National Association, as trustee for the

registered holders of Citigroup Commercial Mortgage Trust 2006-C5,

Commercial Mortgage Pass-Through Certificates, Series 2006-C5" (and, in the

case of any A/B Loan Combination, also on behalf of the related

(ix) an original or a copy of any (A) Ground Lease and ground

(x) any intercreditor, co-lender or similar agreement relating to

permitted debt of the Mortgagor; and

4

(xi) copies of any loan agreement, escrow agreement, security

agreement or letter of credit relating to a Trust Mortgage Loan.

No later than the Closing Date, the Seller shall, on behalf of the

Purchaser, deliver or cause to be delivered to the Trustee (with a copy to the

Master Servicer and the Special Servicer within ten (10) Business Days after the

Closing Date) the documents and instruments specified below with respect to each

of the Ala Moana Portfolio Trust Mortgage Loans (with respect to each Ala Moana

Portfolio Trust Mortgage Loan, the documents and instruments specified below,

collectively, the "Mortgage File"). The Mortgage File for each Ala Moana

Portfolio Trust Mortgage Loan shall contain the following documents:

(x) the original executed Mortgage Note for such Trust Mortgage Loan,

endorsed (without recourse, representation or warranty, express or implied)

to the order of "Wells Fargo Bank, National Association, as trustee for the

registered holders of Citigroup Commercial Mortgage Trust 2006-C5,

Commercial Mortgage Pass-Through Certificates, Series 2006-C5" or in blank

2006-C5, and further showing a complete, unbroken chain of endorsement from

the originator (if such originator is other than the Seller) (or,

alternatively, if the original executed Mortgage Note has been lost, a lost

note affidavit and indemnity with a copy of such Mortgage Note);

(y) a copy of the executed related Co-Lender Agreement; and

(z) a copy of the executed Outside Servicing Agreement (or, if not

delivered on the Closing Date, within five (5) Business Days of the date

such Servicing Agreement is executed).

The Seller hereby further represents and warrants that with respect to the

Ala Moana Portfolio Trust Mortgage Loans, it has delivered to the Outside

Trustee the documents constituting the Mortgage File within the meaning of the

Outside Servicing Agreement in connection with its sale of one of the Ala Moana

Portfolio Pari Passu Non-Trust Loans to the depositor for the commercial

mortgage securitization transaction to which the Outside Servicing Agreement

relates.

With respect to the Crossed Loans constituting a Crossed Group, the

existence of any document required to be in the Mortgage File of any Crossed

Loan in such Crossed Group shall be sufficient to satisfy the requirements of

this Agreement for delivery of such document as a part of the Mortgage File of

each of the other Crossed Loans in such Crossed Group.

References in this Agreement to "Document Defect" mean that any

document constituting part of the Mortgage File for any Mortgage Loan has not

been properly executed, is missing (beyond the time period required for its

delivery hereunder), contains information that does not conform in any material

respect with the corresponding information set forth in the Mortgage Loan

Schedule or does not appear regular on its face.

(d) The Seller, at its own cost and expense, shall retain an

independent third party (the "Recording/Filing Agent") that shall, as to each

Mortgage Loan (other than Outside Serviced Trust Mortgage Loans), promptly (and

in any event, as to any such Mortgage Loan,

5

within 90 days following the latest of (i) the Closing Date and (ii) the

delivery of the related Mortgage(s), Assignment(s) of Leases, recordable

documents, and UCC Financing Statements to the Trustee complete (if and to the

extent necessary) and cause to be submitted for recording or filing, as the case

may be, in the appropriate public office for real property records or UCC

Financing Statements, as appropriate, each assignment of Mortgage, assignment of

Assignment of Leases and assignment of any other recordable documents relating

to each such Mortgage Loan, in favor of the Trustee referred to in Sections

2(c)(iv)(A), (B) and (C) and each assignment of a UCC Financing Statement in

favor of the Trustee and so delivered to the Trustee and referred to in Section

2(c)(viii). The Seller shall cause the recorded original of each such assignment

of recordable documents to be delivered to the Trustee or its designee following

recording, and shall cause the file copy of each such UCC Financing Statement to

be delivered to the Trustee or its designee following filing; provided that in

those instances where the public recording office retains the original

assignment of Mortgage or assignment of Assignment of Leases, the Seller or the

Recording/Filing Agent shall obtain therefrom a certified copy of the recorded

original, which shall be delivered to the Trustee or its designee. If any such

document or instrument is lost or returned unrecorded or unfiled, as the case

may be, because of a defect therein, the Seller shall promptly prepare or cause

to be prepared a substitute therefor or cure such defect, as the case may be,

and thereafter cause the same to be duly recorded or filed, as appropriate. The

Seller shall be responsible for the out-of-pocket costs and expenses of the

Recording/Filing Agent in connection with its performance of the recording,

filing and delivery obligations contemplated above.

(e) The Seller shall deliver or cause to be delivered to the

applicable Master Servicer or such Master Servicer's designee: (i) within ten

(10) days after the Closing Date, all documents and records in the Seller's

possession (except draft documents, attorney-client privileged communications

and internal correspondence, credit underwriting or due diligence analyses,

credit committee briefs or memoranda or other internal approval documents or

data or internal worksheets, memoranda, communications or evaluations and other

underwriting analysis of the Seller) relating to, and necessary for the

servicing and administration of, each Mortgage Loan (other than an Outside

Serviced Trust Mortgage Loan) and that are not required to be part of the

Mortgage File in accordance with the definition thereof (including, without

limitation, any original letters of credit relating to any Mortgage Loan); and

(ii) within two (2) Business Days after the Closing Date, any and all escrow

amounts and reserve amounts in the Seller's possession or under its control that

relate to the Mortgage Loans (other than the Outside Serviced Trust Mortgage

Loans).

(f) The Seller shall take such actions as are reasonably necessary to

assign or otherwise grant to the Trust Fund the benefit of any letters of credit

in the name of the Seller which secure any Mortgage Loan (other than an Outside

Serviced Trust Mortgage Loan). Without limiting the generality of the foregoing,

if a draw upon a letter of credit is required before its transfer to the Trust

Fund can be completed, the Seller shall draw upon such letter of credit for the

benefit of the Trust pursuant to written instructions from the applicable Master

Servicer.

(g) After the Seller's transfer of the Mortgage Loans to or at the

direction of the Purchaser, the Seller shall not take any action to suggest that

the Purchaser is not the legal owner of the Mortgage Loans.

6

SECTION 3. Representations, Warranties and Covenants of Seller.

(a) The Seller hereby represents and warrants to and covenants with

the Purchaser, as of the date hereof, that:

(i) The Seller is a national banking association organized and

validly existing and in good standing under the laws of the United States

and possesses all requisite authority, power, licenses, permits and

franchises to carry on its business as currently conducted by it and to

execute, deliver and comply with its obligations under the terms of this

Agreement;

(ii) This Agreement has been duly and validly authorized,

executed and delivered by the Seller and, assuming due authorization,

execution and delivery hereof by the Purchaser, constitutes a legal, valid

and binding obligation of the Seller, enforceable against the Seller in

accordance with its terms, except as such enforcement may be limited by

bankruptcy, insolvency, reorganization, receivership, moratorium and other

laws affecting the enforcement of creditors' rights in general, as they may

be applied in the context of the insolvency of a national banking

association, and by general equity principles (regardless of whether such

enforcement is considered in a proceeding in equity or at law), and by

public policy considerations underlying the securities laws, to the extent

that such public policy considerations limit the enforceability of the

provisions of this Agreement which purport to provide indemnification from

liabilities under applicable securities laws;

(iii) The execution and delivery of this Agreement by the Seller

and the Seller's performance and compliance with the terms of this

Agreement will not (A) violate the Seller's organizational documents, (B)

violate any law or regulation or any administrative decree or order to

which it is subject or (C) constitute a material default (or an event

which, with notice or lapse of time, or both, would constitute a material

default) under, or result in the breach of, any material contract,

agreement or other instrument to which the Seller is a party or by which

the Seller is bound, which violation, default or breach, in the case of

either clause (iii)(B) or (iii)(C) might have consequences that would, in

the Seller's reasonable and good faith judgment, materially and adversely

affect the financial condition or the operations of the Seller or its

properties (taken as a whole) or have consequences that would materially

and adversely affect its performance hereunder;

(iv) The Seller is not in default with respect to any order or

decree of any court or any order, regulation or demand of any federal,

state, municipal or other governmental agency or body, which default might

have consequences that would, in the Seller's reasonable and good faith

judgment, materially and adversely affect the financial condition or the

operations of the Seller or its properties (taken as a whole) or have

consequences that would materially and adversely affect its performance

hereunder;

(v) The Seller is not a party to or bound by any agreement or

instrument or subject to any other corporate restriction or any judgment,

order, writ, injunction, decree, law or regulation that would, in the

Seller's reasonable and good faith

7

judgment, materially and adversely affect the ability of the Seller to

perform its obligations under this Agreement or that requires the consent

of any third person to the execution of this Agreement or the performance

by the Seller of its obligations under this Agreement (except to the extent

such consent has been obtained);

(vi) No consent, approval, authorization or order of any court or

governmental agency or body is required for the execution, delivery and

performance by the Seller of, or compliance by the Seller with, this

Agreement or the consummation of the transactions involving the Seller

contemplated by this Agreement except as have previously been obtained, and

no bulk sale law applies to such transactions;

(vii) No litigation is pending or, to the Seller's knowledge,

threatened against the Seller that would, in the Seller's good faith and

reasonable judgment, prohibit its entering into this Agreement or

materially and adversely affect the performance by the Seller of its

obligations under this Agreement; and

(viii) For purposes of accounting under generally accepted

accounting principles ("GAAP"), and for federal income tax purposes, the

Seller will report the transfer of the Mortgage Loans to the Purchaser as a

sale of the Mortgage Loans to the Purchaser in exchange for consideration

contemplated by this Agreement. The consideration received by the Seller

upon the sale of the Mortgage Loans to the Purchaser will constitute at

least reasonably equivalent value and fair consideration for the Mortgage

Loans. The Seller will be solvent at all relevant times prior to, and will

not be rendered insolvent by, the sale of the Mortgage Loans to the

Purchaser. The Seller is not transferring the Mortgage Loans to the

Purchaser with any intent to hinder, delay or defraud any of the creditors

of the Seller or on account of an antecedent debt.

(b) The Seller hereby makes, on the date hereof and on the Closing

Date, the representations and warranties contained in Schedule I and Schedule II

hereto with respect to each Mortgage Loan, for the benefit of the Purchaser,

which representations and warranties are subject to the exceptions set forth on

Schedule III. References in this Agreement to "Breach" mean a breach of any such

representations and warranties made pursuant to this Section 3(b) with respect

to any Mortgage Loan.

(c) If the Seller receives, pursuant to Section 2.03(a) of the Pooling

and Servicing Agreement, written notice of a Document Defect or a Breach

relating to a Mortgage Loan, and if such Document Defect or Breach shall

materially and adversely affect the value of the applicable Mortgage Loan or the

interests of the Certificateholders therein, then the Seller shall, not later

than ninety (90) days from receipt of such notice (or, in the case of a Document

Defect or Breach relating to a Mortgage Loan not being a "qualified mortgage"

within the meaning of the REMIC Provisions (a "Qualified Mortgage"), not later

than ninety (90) days from any party to the Pooling and Servicing Agreement

discovering such Document Defect or Breach, provided the Seller receives such

notice in a timely manner), cure such Document Defect or Breach, as the case may

be, in all material respects, or, if such Document Defect or Breach (other than

omissions solely due to a document not having been returned by the related

recording office) cannot be cured within such 90-day period, (i) repurchase the

affected Mortgage Loan at the applicable Purchase Price not later than the end

of such 90-day period, or (ii) substitute a

8

Qualified Substitute Mortgage Loan for such affected Mortgage Loan (other than

an Ala Moana Portfolio Subordinate Trust Mortgage Loan, for which no

substitution is permitted) not later than the end of such 90-day period (and in

no event later than the second anniversary of the Closing Date) and pay the

applicable Master Servicer for deposit into its Collection Account, any

Substitution Shortfall Amount in connection therewith; provided that, if a

Document Defect or Breach is capable of being cured but not within such 90-day

period and the Seller has commenced and is diligently proceeding with the cure

of such Document Defect or Breach within such 90-day period, then unless such

Document Defect or Breach would cause the Mortgage Loan not to be a Qualified

Mortgage, such Seller shall have an additional 90 days to complete such cure

(or, failing such cure, to repurchase or substitute for the related Mortgage

Loan); and provided, further, that with respect to such additional 90-day period

the Seller shall have delivered an officer's certificate to the Trustee setting

forth what actions the Seller is pursuing in connection with the cure thereof

and stating that the Seller anticipates that such Document Defect or Breach will

be cured within the additional 90-day period; and provided, further, that if the

cure of any Document Defect or Breach would require an expenditure on the part

of the Seller in excess of $10,000, then the Seller may, at its option, within

the time period provided above, elect to purchase or replace the affected

Mortgage Loan in accordance with this Section 3 without attempting to cure such

Document Defect that, to the Seller's knowledge, existed as of the Closing Date,

or Breach, as the case may be. For a period of two years from the Closing Date,

so long as there remains any Mortgage File relating to a Mortgage Loan as to

which there is an uncured Document Defect that shall materially and adversely

affect the value of the applicable Mortgage Loan or the interests of the

Certificateholders therein, the Seller shall provide the officer's certificate

to the Trustee described above as to the reasons such Document Defect remains

uncured and as to the actions being taken to pursue cure.

No substitution of a Qualified Substitute Mortgage Loan or Qualified

Substitute Mortgage Loans may be made in any calendar month after the

Determination Date in such month. Periodic Payments due with respect to any

Qualified Substitute Mortgage Loan after the related due date in the month of

substitution shall be part of the Trust Fund, and Periodic Payments received

with respect to the replaced Mortgage Loan or a repurchased Mortgage Loan after

the related date of substitution or repurchase, as the case may be, shall belong

to the Seller. Periodic Payments due with respect to any Qualified Substitute

Mortgage Loan on or prior to the related due date in the month of substitution

shall not be part of the Trust Fund and shall be remitted to the Seller promptly

following receipt, and Periodic Payments received with respect to the replaced

Mortgage Loan or a repurchased Mortgage Loan up to and including the related

date of substitution or repurchase, as the case may be, shall belong to the

Trust Fund.

(d) If (i) any Mortgage Loan is required to be repurchased or

substituted for in the manner described above, (ii) such Mortgage Loan is a

Crossed Loan, and (iii) the applicable Document Defect or Breach does not

constitute a Document Defect or Breach, as the case may be, as to any other

Crossed Loan in such Crossed Group (without regard to this paragraph), then the

applicable Document Defect or Breach, as the case may be, will be deemed to

constitute a Document Defect or Breach, as the case may be, as to each other

Crossed Loan in the Crossed Group for purposes of this paragraph, and the Seller

will be required to repurchase or substitute for the remaining Crossed Loan(s)

in the related Crossed Group as provided in the immediately preceding paragraph

unless: (x) such other Crossed Loans in such Crossed Group satisfy the Crossed

Loan Repurchase Criteria; (y) the Seller (at its expense) shall have furnished

the Trustee

9

with an Opinion of Counsel to the effect that the repurchase of or substitution

for the affected Crossed Loan only, including, without limitation, any

modification required with respect to such repurchase or substitution, shall not

cause an Adverse REMIC Event; and (z) the repurchase of or substitution for the

affected Crossed Loan only shall satisfy all other criteria for repurchase or

substitution, as applicable, of Mortgage Loans set forth herein or in the

Pooling and Servicing Agreement. If the conditions set forth in clauses (x), (y)

and (z) of the prior sentence are satisfied, the Seller may elect either to

repurchase or substitute for only the affected Crossed Loan as to which the

related Document Defect or Breach exists or to repurchase or substitute for all

of the Crossed Loans in the related Crossed Group. The Seller shall be

responsible for the cost of any Appraisal required to be obtained by the

applicable Master Servicer to determine if the Crossed Loan Repurchase Criteria

have been satisfied, so long as the scope and cost of such Appraisal has been

approved by the Seller (such approval not to be unreasonably withheld). To the

extent that the Seller is required to purchase or substitute for a Crossed Loan

hereunder in the manner prescribed above while the Purchaser continues to hold

any other Crossed Loans in such Crossed Group, neither the Seller nor the

Purchaser shall enforce any remedies against the other's Primary Collateral, but

each is permitted to exercise remedies against the Primary Collateral securing

its respective Crossed Loans, including, with respect to the Purchaser, the

Primary Collateral securing the Crossed Loans still held by the Purchaser, so

long as such exercise does not materially impair the ability of the other party

to exercise its remedies against its Primary Collateral.

If the exercise of remedies by one party would materially impair the

ability of the other party to exercise its remedies with respect to the Primary

Collateral securing the Crossed Loans held by such party, then the Seller and

the Purchaser shall forbear from exercising such remedies until the Mortgage

Loan documents evidencing and securing the relevant Crossed Loans can be

modified in a manner that complies with this Agreement to remove the threat of

material impairment as a result of the exercise of remedies or some other

accommodation can be reached. Any reserve or other cash collateral or letters of

credit securing the Crossed Loans shall be allocated between such Crossed Loans

in accordance with the Mortgage Loan documents or, if not specified in the

related Mortgage Loan documents, on a pro rata basis based upon their

outstanding Stated Principal Balances. Notwithstanding the foregoing, if a

Crossed Loan included in the Trust Fund is modified to terminate the related

cross-collateralization and/or cross-default provisions, as a condition to such

modification, the Seller shall furnish to the Trustee an Opinion of Counsel that

such modification shall not cause an Adverse REMIC Event. Any expenses incurred

by the Purchaser in connection with such modification or accommodation

(including but not limited to recoverable attorney fees) shall be paid by the

Seller.

Notwithstanding any of the foregoing provisions of this Section 3(d),

if there is a Document Defect or Breach (which Document Defect or Breach shall

materially and adversely affect the value of the related Mortgage Loan or the

interests of the Certificateholders therein) with respect to one or more

Mortgaged Properties with respect to a Mortgage Loan, the Seller shall not be

obligated to repurchase or replace the Mortgage Loan if (i) the affected

Mortgaged Property(ies) may be released pursuant to the terms of any partial

release provisions in the related Mortgage Loan documents (and such Mortgaged

Property(ies) are, in fact, released) and, to the extent not covered by the

applicable release price (if any) required under the related Mortgage Loan

documents, the Seller pays (or causes to be paid) any additional amounts

necessary to cover all reasonable out-of-pocket expenses reasonably incurred by

the applicable

10

Master Servicer, the Special Servicer, the Trustee, the Certificate

Administrator or the Trust Fund in connection with such release, (ii) the

remaining Mortgaged Property(ies) satisfy the requirements, if any, set forth in

the related Mortgage Loan documents and the Seller provides an opinion of

counsel to the effect that such release would not cause any REMIC created under

the Pooling and Servicing Agreement to fail to qualify as a REMIC under the Code

or result in the imposition of any tax on "prohibited transactions" or

whether such enforcement is considered in a proceeding in equity or at law).

(c) The Purchaser is not a party to or bound by any agreement or

instrument or subject to any other corporate restriction or any judgment, order,

writ, injunction, decree, law or regulation that would, in the Purchaser's

reasonable and good faith judgment, materially and adversely affect the ability

of the Purchaser to perform its obligations under this Agreement or that

requires the consent of any third person to the execution of this Agreement or

the performance by the Purchaser of its obligations under this Agreement (except

to the extent such consent has been obtained).

(d) No consent, approval, authorization or order of any court or

governmental agency or body is required for the execution, delivery and

performance by such Purchaser of, or compliance by such Purchaser with, this

Agreement or the consummation of the transactions of such contemplated by this

Agreement, except for any consent, approval, authorization or order which has

been obtained prior to the actual performance by such Purchaser of its

obligations under this Agreement, or which, if not obtained would not have a

materially adverse effect on the ability of such Purchaser to perform its

obligations hereunder.

(e) None of the acquisition of the Mortgage Loans by the Purchaser,

the transfer of the Mortgage Loans to the Trustee, and the execution, delivery

or performance of this Agreement by the Purchaser, results or will result in the

or conflicts or will conflict with, results or will result in a breach of, or

constitutes or will constitute a default under (i) any term or provision of the

Purchaser's articles of association or bylaws, (ii) any term or provision of any

material agreement, contract, instrument or indenture, to which the Purchaser is

a party or by which the Purchaser is bound, or (iii) any law, rule, regulation,

order, judgment, writ, injunction or decree of any court or governmental

authority having jurisdiction over the Purchaser or its assets, which default

might have consequences that would, in the Purchaser's reasonable and good faith

judgment, materially and adversely affect the condition (financial or other) or

operations of the Purchaser or its properties or have consequences that would

materially and adversely affect its performance hereunder.

(f) Under GAAP and for federal income tax purposes, the Purchaser will

report the transfer of the Mortgage Loans by the Seller to the Purchaser as a

sale of the Mortgage Loans to the Purchaser in exchange for the consideration

contemplated by this Agreement.

(g) There is no action, suit, proceeding or investigation pending or

to the knowledge of the Purchaser, threatened against the Purchaser in any court

or by or before any other governmental agency or instrumentality which would, in

the Purchaser's reasonable and good faith judgment, materially and adversely

affect the validity of this Agreement or any action taken in connection with the

obligations of the Purchaser contemplated herein, or which would be likely to

impair materially the ability of the Purchaser to enter into and/or perform

under the terms of this Agreement.

12

(h) The Purchaser is not in default with respect to any order or

decree of any court or any order, regulation or demand of any federal, state,

SECTION 8. Grant of a Security Interest. It is the express intent of

the parties hereto that the conveyance of the Mortgage Loans by the Seller to

the Purchaser as provided in Section 2 hereof be, and be construed as, a sale of

the Mortgage Loans by the Seller to the Purchaser and not as a pledge of the

Mortgage Loans by the Seller to the Purchaser to secure a debt or other

obligation of the Seller. However, if, notwithstanding the aforementioned intent

of the parties, the Mortgage Loans are held to be property of the Seller, then,

(a) it is the express intent of the parties that such conveyance be deemed a

pledge of the Mortgage Loans by the Seller to the Purchaser to secure a debt or

other obligation of the Seller, and (b) (i) this Agreement shall also be deemed

to be a security agreement within the meaning of Article 9 of the Uniform

Commercial Code of the applicable jurisdiction; (ii) the conveyance provided for

in Section 2 hereof shall be deemed to be a grant by the Seller to the Purchaser

of a security interest in all of the Seller's right, title and interest in and

to the Mortgage Loans, and all amounts payable to the holder of the Mortgage

Loans in accordance with the terms thereof, and all proceeds of the conversion,

voluntary or involuntary, of the foregoing into cash, instruments, securities or

other property, including, without limitation, all amounts, other than

investment earnings, from time to time held or invested in the Collection

Accounts, the Distribution Account or, if established, the REO Accounts (each as

defined in the Pooling and Servicing Agreement) whether in the form of cash,

instruments, securities or other property; (iii) the assignment to the Trustee

of the interest of the Purchaser in and to the Mortgage Loans pursuant to the

Pooling and Servicing Agreement, as contemplated by Section 1 hereof shall be

deemed to be an assignment of any security interest created hereunder; (iv) the

possession by the Trustee or any of its agents, including, without limitation,

the Custodian, of the Mortgage Notes, and such other items of

15

property as constitute instruments, money, negotiable documents or chattel paper

shall be deemed to be possession by the secured party for purposes of perfecting

the security interest pursuant to Section 9-313 of the Uniform Commercial Code

of the applicable jurisdiction; and (v) notifications to persons (other than the

Trustee) holding such property, and acknowledgments, receipts or confirmations

from persons (other than the Trustee) holding such property, shall be deemed

notifications to, or acknowledgments, receipts or confirmations from, securities

intermediaries, bailees or agents (as applicable) of the secured party for the

purpose of perfecting such security interest under applicable law. The Seller

and the Purchaser shall, to the extent consistent with this Agreement, take such

actions as may be necessary to ensure that, if this Agreement were deemed to

create a security interest in the Mortgage Loans, such security interest would

be deemed to be a perfected security interest of first priority under applicable

law and will be maintained as such throughout the term of this Agreement and the

Pooling and Servicing Agreement, and in connection therewith the Seller

authorizes the Purchaser to file any and all appropriate Uniform Commercial Code

financing statements.

SECTION 9. Notices. All notices, copies, requests, consents, demands

and other communications in connection herewith shall be in writing and

telecopied or delivered to the intended recipient at the "Address for Notices"

specified for such party on Exhibit A hereto or, as to either party, at such

other address as shall be designated by such party in a notice hereunder to the

other party. Except as otherwise provided in this Agreement, all such

telecopier or personally delivered or, in the case of a mailed notice, upon

SECTION 10. Representations, Warranties and Agreements to Survive

Delivery. All representations, warranties and agreements contained in this

Agreement, incorporated herein by reference or contained in the certificates of

officers of the Seller submitted pursuant hereto, shall remain operative and in

full force and effect and shall survive delivery of the Mortgage Loans by the

Seller to the Purchaser (and by the Purchaser to the Trustee).

SECTION 11. Severability of Provisions. Any part, provision,

representation, warranty or covenant of this Agreement that is prohibited or

which is held to be void or unenforceable shall be ineffective to the extent of

such prohibition or unenforceability without invalidating the remaining

provisions hereof. Any part, provision, representation, warranty or covenant of

this Agreement that is prohibited or unenforceable or is held to be void or

unenforceable in any particular jurisdiction shall, as to such jurisdiction, be

ineffective to the extent of such prohibition or unenforceability without

invalidating the remaining provisions hereof, and any such prohibition or

unenforceability in any particular jurisdiction shall not invalidate or render

unenforceable such provision in any other jurisdiction. To the extent permitted

by applicable law, the parties hereto waive any provision of law which prohibits

or renders void or unenforceable any provision hereof.

SECTION 12. Counterparts. This Agreement may be executed in any number

of counterparts, each of which shall be an original, but which together shall

constitute one and the same agreement.

16

OBLIGATIONS AND RESPONSIBILITIES OF THE PARTIES HERETO SHALL BE GOVERNED IN

is commenced between the Seller and the Purchaser regarding their respective

rights and obligations under this Agreement, the prevailing party shall be

entitled to recover, in addition to damages or other relief, costs and expenses,

attorneys' fees and court costs (including, without limitation, expert witness

fees). As used herein, the term "prevailing party" shall mean the party which

obtains the principal relief it has sought, whether by compromise settlement or

judgment. If the party which commenced or instituted the action, suit or

proceeding shall dismiss or discontinue it without the concurrence of the other

party, such other party shall be deemed the prevailing party.

SECTION 15. Further Assurances. The Seller and the Purchaser agree to

execute and deliver such instruments and take such further actions as the other

party may, from time to time, reasonably request in order to effectuate the

purposes and to carry out the terms of this Agreement.

SECTION 16. Successors and Assigns. The rights and obligations of the

Seller under this Agreement shall not be assigned by the Seller without the

prior written consent of the Purchaser, except that any person into which the

Seller may be merged or consolidated, or any corporation resulting from any

merger, conversion or consolidation to which the Seller is a party, or any

person succeeding to all or substantially all of the business of the Seller,

shall be the successor to the Seller hereunder. The Purchaser has the right to

assign its interest under this Agreement, in whole or in part, as may be

required to effect the purposes of the Pooling and Servicing Agreement, and the

assignee shall, to the extent of such assignment, succeed to the rights and

obligations hereunder of the Purchaser. Subject to the foregoing, this Agreement

shall bind and inure to the benefit of and be enforceable by the Seller, the

Purchaser and their permitted successors and assigns. No holder or beneficial

owner of a Certificate shall be deemed a permitted successor or assign to the

Purchaser solely by reason of its interest in such Certificate.

SECTION 17. Amendments. No term or provision of this Agreement may be

waived or modified unless such waiver or modification is in writing and signed

by a duly authorized officer of the party against whom such waiver or

modification is sought to be enforced. No amendment to the Pooling and Servicing

have agreed to such amendment in writing.

with accountants designated by CCMSI and reasonably acceptable to the Seller in

making available

17

all information and taking all steps reasonably necessary to permit such

accountants to deliver the letters required by the Underwriting Agreement and/or

the Certificate Purchase Agreement.

statement in this Agreement is made with respect to a Person's "knowledge", such

statement refers to such Person's employees or agents who were or are

responsible for or involved with the indicated matter and have actual knowledge

of the matter in question.

SECTION 20. Disclosure Materials. The Purchaser shall provide the

Seller with a copy of the Memorandum and the Prospectus Supplement promptly

following their becoming available.

SCHEDULE I

GENERAL MORTGAGE REPRESENTATIONS AND WARRANTIES

1. The information pertaining to each Mortgage Loan set forth in the

Mortgage Loan Schedule was true and correct in all material respects as of the

Cut-off Date.

2. As of the date of its origination, such Mortgage Loan and the interest

(exclusive of any default interest, late charges or prepayment premiums)

contracted for thereunder, complied in all material respects with, or was exempt

from, all requirements of federal, state or local law relating to the

origination of such Mortgage Loan, including those pertaining to usury.

3. Immediately prior to the sale, transfer and assignment to the Purchaser,

the Seller had good title to, and was the sole owner of, each Mortgage Loan and

the Seller is transferring such Mortgage Loan free and clear of any and all

liens, pledges, charges or security interests of any nature encumbering such

Mortgage Loan, but subject to certain agreements regarding servicing as provided

in the Pooling and Servicing Agreement, subservicing agreements permitted

thereunder and that certain Servicing Rights Purchase Agreement dated as of the

Closing Date between the applicable Master Servicer and the Seller. Upon

consummation of the transactions contemplated by the Mortgage Loan Purchase

Agreement, the Seller will have validly and effectively conveyed to the

Purchaser all legal and beneficial interest in and to such Mortgage Loan free

and clear of any pledge, lien or security interest.

4. The proceeds of such Mortgage Loan have been fully disbursed (except to

the extent that a portion of such proceeds is being held in escrow or reserve

accounts) and there is no requirement for future advances thereunder by the

Mortgagee.

5. Each related Mortgage Note, Mortgage, Assignment of Leases (if any) and

other agreement executed by the Mortgagor in connection with such Mortgage Loan

is a legal, valid and binding obligation of the related Mortgagor (subject to

any non-recourse provisions therein and any state anti-deficiency or market

value limit deficiency legislation), enforceable in accordance with its terms,

except (a) that certain provisions contained in such Mortgage Loan documents are

or may be unenforceable in whole or in part under applicable state or federal

laws, but neither the application of any such laws to any such provision nor the

inclusion of any such provisions renders any of the Mortgage Loan documents

invalid as a whole and such Mortgage Loan documents taken as a whole are

enforceable to the extent necessary and customary for the practical realization

of the principal rights and benefits afforded thereby and (b) as such

enforcement may be limited by bankruptcy, insolvency, receivership,

reorganization, moratorium, redemption, liquidation or other laws affecting the

enforcement of creditors' rights generally, or by general principles of equity

(regardless of whether such enforcement is considered in a proceeding in equity

or at law). The related Mortgage Note and Mortgage contain no

I-2

provision limiting the right or ability of the Seller to assign, transfer and

convey the related Mortgage Loan to any other Person.

6. As of the date of its origination, there was no valid offset, defense,

counterclaim, abatement or right to rescission with respect to any of the

related Mortgage Notes, Mortgage(s) or other agreements
