included in a securitization undertaken in accordance with Section 4.01. Column

date on which such Approved Loan is approved as an Approved Loan hereunder. Each

the time of intended securitization, it satisfies the requirements of the
relevant rating agencies.

        (b)   The party seeking approval of a Loan ("Applicant") shall submit to
the party from whom approval is being sought ("Reviewer") an application package

                (xvi) any draft receivables agreements, which shall include the
        amount of the related receivable line.

                (c) Reviewer shall, in writing, approve or reject the proposed
Loan within seven (7) Business Days after receipt of all items listed in Section
2.02(b) above. Should any such items be materially modified or amended after
being submitted to Reviewer, Applicant shall resubmit such modified or amended
items to Reviewer for approval in accordance with this Section 2.02.
Notwithstanding anything contained herein to the contrary and regardless of
whether the proposed Loan meets the Eligibility Criteria, a Reviewer may reject
any proposed Loan in its absolute discretion.

                (d) In connection with the process provided for in this Section
2.02, Applicant agrees, with respect to each Loan submitted by it for approval,
to investigate completely and thoroughly every underwriting and legal matter in
accordance with the Underwriting Guidelines, and, with respect to matters not
addressed by the Underwriting Guidelines, to use such origination and

and originating Loans comparable to the subject mortgage loans and exercising a
standard of care customary in the commercial mortgage lending industry. In
addition, Applicant agrees to use the form documents attached as Exhibit C in
originating the Loans submitted for approval hereunder and to only make those
changes to such forms as are reasonably necessary.

                (e) Loans may be submitted by CapitalSource for approval
hereunder only so long as (i) CapitalSource is entitled to submit Loans for
financing under the Repo Agreement and (ii) no Event of Default has occurred and
is continuing.

                Section 2.03 Registration of Loans. CSFB and CapitalSource agree
to utilize CSFB's loan registry (located at www2.columnfinancial.com/pipeline/)
(the "Pipeline Registry").

                                  ARTICLE III

                       PURCHASE OF PARTICIPATION INTERESTS

                Section 3.01 Participation Interests. CapitalSource agrees to
purchase from Column a 20% subordinate, first-loss participation interest (a
"Junior Participation Interest") in any Approved Loan originated by Column.
Column will initially retain an 80% senior participation interest in such loans
(a "Senior Participation Interest" and, together with the Junior Participation
Interest, the "Participation Interests"). CapitalSource shall purchase each
Junior Participation Interest at a price equal to par, and such Junior
Participation Interest will accrue interest in an amount equal to the lesser of
(i) a portion of the mortgage interest accruals on the Approved Loan such that
CapitalSource receives a 20% annualized yield on such Junior Participation
Interest, or (ii) 100% of the mortgage interest accruals on such Approved Loan.

                Section 3.02 Participation Agreement. The Participation
Interests in each Approved Loan will be governed by the terms of a participation
agreement between Column and CapitalSource (each, a "Participation Agreement")
substantially in the form attached hereto as Exhibit D.

                                   ARTICLE IV

                        SECURITIZATION OF APPROVED LOANS

        Section 4.01   Timing of Securitizations.

        (a)   At such time as the parties mutually agree, CapitalSource and CSFB
shall arrange for the securitization of any or all existing Approved Loans (each
such securitization, a "Securitization"). The decision of the parties to
commence a Securitization shall be binding on such parties, unless (i) either
party notifies the other party of its decision to withdraw from the
Securitization within two Business Days after receipt of preliminary
subordination levels from the relevant rating agencies or (ii) the actual final
subordination levels required by the relevant rating agencies to support
investment-grade securities (i.e., the principal balance of all securities rated
below "BBB-") exceeds the preliminary subordination levels indicated by the
rating agencies with respect to such securities by more than 2% of the aggregate
principal balance of the Approved Loans to be included in such proposed
securitization.

        (b)   In the event that CapitalSource and CSFB cannot mutually agree to
arrange for the securitization of the Approved Loans, CSFB may elect to
securitize its Senior Participation Interests at any time in its sole discretion
(each such securitization of the Senior Participation Interests, a "Senior
Participation Securitization"). CSFB shall ensure that any servicing agreement
prepared in connection with any Senior Participation Securitization is not
inconsistent with any related Participation Agreement.

        Section 4.02 General Structure of Securitization. CSFB shall cause its
affiliate, Credit Suisse First Boston Mortgage Securities Corp. (the
"Depositor"), to act as depositor of each Securitization. With respect to each
Securitization, CapitalSource will sell the Approved Loans that it originated,
and each of CapitalSource and Column will sell its respective

                                      -9-
<PAGE>


Participation Interest in the Approved Loan originated by Column, to the
Depositor pursuant to a mortgage loan purchase and sale agreement in form and
substance customary for similar transactions and acceptable to the relevant
rating agencies. Following the purchase by the Depositor of both Participation
Interests with respect to any Loan, the Participation Agreement with respect to
such Loan shall be terminated. The Depositor shall have control over the
structure of the Securitization and shall manage the Securitization process
(including the selection of rating agencies and hiring of service providers
(including, without limitation, the lead counsel, accountants, financial printer
and trustee) in connection therewith), subject to the requirements of this
Article IV. Notwithstanding the foregoing, CapitalSource shall have the right to
disapprove any major decision of the Depositor with respect to a Securitization
to the extent that CapitalSource reasonably disagrees with such decision;
provided that all decisions with respect to a Securitization undertaken pursuant
to Section 4.01(b) shall be made by the Depositor in its sole and absolute
discretion. With respect to each Securitization, each of CapitalSource and
Column agree to provide any additional documents related to the origination of
the subject mortgage loans as required by the relevant rating agencies.

                Section 4.03  Purchase of Securities. With respect to each
Securitization, CapitalSource agrees to purchase at closing (or, in the sole
discretion of CSFB, within two weeks thereof) the Subordinated Securities.
Notwithstanding the foregoing, CapitalSource shall have no obligation to
purchase any Subordinated Securities in connection with a Senior Participation
Securitization. "Subordinated Securities" shall mean, with respect to a
Securitization, the greater of (i) all of the securities issued in such
Securitization with a rating by at least one rating agency below "BBB-" or the
equivalent, or (ii) the most subordinated securities issued in such
Securitization having an aggregate principal amount equal to 20% of the
aggregate principal balance of all of the securities issued in such
Securitization (the portion of such Subordinated Securities having a rating of
at least "BBB-" or the equivalent being referred to herein as the "Investment
Grade Subordinate Securities"). CapitalSource shall pay a purchase price to the
Depositor for the Subordinated Securities equal to 100% of the principal balance
thereof (which purchase price shall be a portion of the aggregate Securitization
proceeds to be divided pursuant to Section 4.04). In connection with each such
purchase of securities, CapitalSource shall make representations and warranties
that are customary for the purchaser of securities to make in similar
transactions.

        Section 4.04   Division of Securitization Proceeds; Excess Spread.

        (a)   Each Securitization shall be in a multi-class, senior/subordinated
trust structure. The interest rates on the various classes of investment grade
securities shall be set so as to achieve the maximum aggregate sales prices for
such classes. The classes of Subordinated Securities shall accrue interest at a
rate equal to the sum of (i) the weighted average of the interest rates on the
Approved Loans included in the Securitization (calculated on the basis of a
360-day year of twelve 30-day months), net of trustee and servicing fees (the
"Net WAC") and (ii) the portion of the Excess Spread allocable to CapitalSource
pursuant to the succeeding sentence and Sections 4.04(c) and (d) below. Interest
accruing at a rate equal to the excess of the Net WAC over the weighted average
of the interest rates on the classes of securities other than the Subordinated
Securities on a notional balance equal to the aggregate principal balance of
such classes (calculated on the basis of a 360-day year of twelve 30-day months)
("Excess Spread") shall be divided between CapitalSource (as increased interest
on the Subordinated

                                      -10-
<PAGE>


Securities) (the "CapitalSource Excess Spread") and a class of interest-only
securities to be purchased by CSFB ( the "CSFB IO Class").

        (b)   With respect to each Securitization, the actual proceeds of the
sale of all classes of securities other than the CSFB IO Class and the
Subordinated Securities (with the proceeds of the sale of the Subordinated
Securities being assumed for purposes of this Section 4.04(b) to be par) and the
assumed proceeds of the sale of the Subordinated Securities (collectively for
each Securitization, the "Aggregate Securitization Proceeds"), exclusive of
accrued interest collected shall be allocated pro rata in accordance with the
principal balance of Loans and Participation Interests contributed to the
Securitization by Column on the one hand and CapitalSource on the other. Accrued
interest collected from the sale of all certificates in connection with a
Securitization, including the CSFB IO and Excess Spread allocated to
CapitalSource in Section 4.04(c), shall be allocated pro rata based on the CSFB
Accrued Interest Amount and the CapitalSource Accrued Interest Amount. Aggregate
Securitization Proceeds allocated to CapitalSource will be applied first in
reduction of the assumed purchase price of the Subordinated Securities before
any actual proceeds are distributed to CapitalSource.

        (c)   With respect to each Securitization, CapitalSource shall be
entitled to the CapitalSource IO Percentage (as defined below) of the Excess
Spread (by notional balance). CapitalSource will further be entitled to the
portion, if any, of the CSFB IO Percentage (as defined below) of the Excess
Spread (by notional balance) which, when added to the interest accruing on the
CSFB Junior Certificates (as defined below at the pass-through rate thereof,
will give CapitalSource the lesser of (i) (A)  a coupon on the aggregate
principal amount of the portion of the CSFB  Junior Certificates constituting
Investment Grade Subordinate Securities (but such portion not to exceed 5% of
the aggregate principal balance of all the securities issued in such
Securitization), of 10%, (calculated on the basis of a 360-day year of twelve
30-day months), plus (B) a coupon on the aggregate principal amount of the
remaining portion of the CSFB Junior Certificates, of 17%, (calculated on the
basis of a 360-day year of twelve 30-day months); or (ii) 100% of the CSFB IO
Percentage of the Excess Spread. Any remaining portion of the CSFB IO Percentage
of the Excess Spread that CapitalSource is not entitled to pursuant to the
preceding sentence will be divided 60% to CSFB and 40% to CapitalSource.

        (d)   In order to calculate the CSFB IO Percentage, the CapitalSource IO
Percentage, the CSFB Junior Percentage, the CapitalSource Junior Percentage, the
CSFB Accrued Interest Amount and the CapitalSource Accrued Interest Amount with
respect to any Securitization, CSFB shall model each Securitization as two
separate securitizations ("Sub-pool Securitizations"), with one such Sub-pool
Securitization including all Loans contributed by CapitalSource and the other
such Sub-pool Securitization including all Loans contributed by Column
(including both Senior Participation Interests and Junior Participation
Interests with respect to such Loans), but otherwise having identical class
structures and pass-through rates (other than (i) the pass-through rates of the
interest only classes, which will be derived from the Net WAC of the related
Loans and the pass-through rates of the other classes (such interest only
coupons, the "Assumed IO Rates"), (ii) class sizes, which will be based upon the
sub-pool subordination levels supplied by the rating agencies rating such
Securitization, and (iii) the pass-through rates of the junior classes, which
will be equal to the Net WAC of the related Loans and (iv) Accrued Interest
Amounts). With respect to a Securitization, (i) the assumed interest only class
from the related Sub-pool Securitization assumed to include the CapitalSource
Loans is

                                      -11-
<PAGE>


referred to as the "CapitalSource IO" and the assumed interest only class from
the related Sub-pool Securitization assumed to include the Column Loans is
referred to as the "CSFB IO," and (ii) the Accrued Interest Amount from the
related Sub-pool Securitization assumed to include the Capital Source Loans is
referred to as the "CapitalSource Accrued Interest Amount" and the Accrued
Interest Amount from the related Sub-pool Securitization assumed to include the
Column Loans is referred to as the "CSFB Accrued Interest Amount." The
"CapitalSource IO Percentage" for each Securitization will be equal to a
fraction, expressed as a percentage, (X) the numerator of which is product of
the initial pass-through rate of the related CapitalSource IO and the initial
notional amount thereof, and (Y) the denominator of which is the sum of the
amount calculated in clause (X) and the product of the initial pass-through rate
of the Related CSFB IO and the initial notional amount thereof. The "CSFB IO
Percentage" for each Securitization will be equal to 100% minus the related
CapitalSource IO Percentage. With respect to a Securitization, the assumed
Subordinated Securities from the related Sub-pool Securitization (i.e., the most
subordinate 20% or, if greater, the non-investment grade classes) assumed to
include the CapitalSource Loans is referred to as the "CapitalSource Junior
Class" and the assumed Subordinated Securities from the related Sub-pool
Securitization (i.e., the most subordinate 20% or, if greater, the
non-investment grade classes) assumed to include the Column Loans is referred to
as the "CSFB Junior Class." The "CapitalSource Junior Percentage" for each
Securitization will be equal to a fraction, expressed as a percentage, (X) the
numerator of which is the principal balance of the CapitalSource Junior Class,
and (Y) the denominator of which is the aggregate principal balance of the
CapitalSource Junior Class and the CSFB Junior Class. The "CSFB Junior
Percentage" for each Securitization will be equal to 100% minus the related
CapitalSource Junior Percentage. The "CSFB Junior Certificates" for any
Securitization will be a portion of the Subordinated Securities issued in such
Securitization equal to the product of the CSFB Junior Percentage and the
aggregate principal balance of the Subordinated Securities.

        (e)   In the event that, with respect to any Securitization, either (i)
par execution is not achieved with respect to any class of certificates (other
than the Subordinated Securities or the CSFB IO Class) or (ii) the projected
performance of the related CapitalSource IO and the related CSFB IO (calculated
using consistent CPR assumptions and other standard assumptions for CMBS
modeling) differ materially from each other (due to variations in lock-out
period or principal payment characteristics of the related Loans), then the
parties shall agree on appropriate variations to the above-described
methodologies for division of Securitization proceeds and Excess Spread.

        (f)   In addition, if the Approved Loans sold by Column or CapitalSource
with respect to any Securitization include loans that accrue interest at a
variable rate that is tied to LIBOR but that, pursuant to the related loan
documents, never falls below a certain minimum rate (such minimum rate, the
"LIBOR Floor"), then the securities issued by such Securitization shall include
a class (or, if such Loans are sold by both Column and CapitalSource into a
particular Securitization, two classes) of interest-only certificates (such
class or classes, the "LIBOR Floor Certificates") which shall represent the
right to receive, with respect to such Approved Loans, the excess, if any, of
the LIBOR Floor over LIBOR. CapitalSource shall be entitled to the LIBOR Floor
Certificates relating to its Approved Loans. The LIBOR Floor Certificates
relating to the Approved Loans contributed by CSFB will be divided in the same

                                      -12-
<PAGE>



manner as, and treated as part of, the CSFB IO Percentage of Excess Spread in
accordance with Section 4.04(c) hereof.

        Section 4.05  Source of Loans for Securitizations. Unless agreed to by
CapitalSource, Column and CSFB (each in its sole discretion), no Loans other
than Approved Loans may be included in any Securitization.

        Section 4.06  Manager of Securitizations. CSFB shall be the sole lead
manager and sole book runner on any securitization of Approved Loans that are
financed under the Repo Agreement.

        Section 4.07  Manager's Fee. CapitalSource will pay CSFB a fee, as
structurer and placement agent/underwriter for each Securitization, of 1.00% of
the total principal balance of all the securities created pursuant to such
Securitization (the "CSFB Fee"). The CSFB Fee with respect to a Securitization
shall be payable on the closing date of such Securitization.

        Section 4.08  Origination and Exit Fees. CapitalSource shall be entitled
to receive all origination fees and exit fees with respect to Approved Loans
originated by CapitalSource and included in a Securitization. CSFB shall be
entitled to receive all origination fees with respect to Approved Loans
originated by Column and included in a Securitization. CapitalSource shall be
entitled to receive all exit fees with respect to Approved Loans originated by
Column and included in a Securitization; provided, however, that CapitalSource
shall not receive any such exit fees in connection with a Senior Participation
Securitization or in the event that it does not purchase the Subordinated
Securities as required by Section 4.03.

        Section 4.09 Servicing.

        (a)   After the origination but prior to the securitization of the Loans
originated by Column, ORIX Real Estate Capital Markets LLC or such other
servicer that is reasonably acceptable to the parties to this Agreement will act
as servicer and CapitalSource will act as special servicer. After the
origination but prior to the securitization of the Loans originated by
CapitalSource, ORIX Real Estate Capital Markets LLC or such other servicer that
is reasonably acceptable to the parties to this Agreement will act as servicer
and CapitalSource will act as primary servicer and special servicer. In each
case, the servicing arrangement shall be documented in a separate interim
servicing agreement (each, an "Interim Servicing Agreement") which shall be in
form and substance reasonably acceptable to the parties hereto. Upon the
consummation of a Securitization or a Senior Participation Securitization, the
Interim Servicing Agreement will terminate with respect to any Approved Loans or
Senior Participation Interests securitized therein and no compensation shall be
due to CapitalSource in connection with such termination.

        (b)   The Depositor shall choose the servicer for each Securitization or
Senior Participation Securitization; provided, that, the servicer of the
Approved Loans that are securitized must be on S&P's approved list of servicers
rated at least CMS3 by Fitch and acceptable to Moody's. CapitalSource shall
choose the special servicer for each Securitization; provided, that, the special
servicer of the Approved Loans that are securitized must be on S&P's approved
list of special servicers and must be acting as special servicer in one or more

                                      -13-

        commercial mortgage loan securitizations that was rated by
        Moody's and Fitch in the prior six (6) months and Moody's or Fitch, as
        applicable, has not downgraded or withdrawn the then-current rating on
        any class of commercial mortgage securities or placed any class of
        commercial mortgage securities on watch citing the continuation of such
        special servicer as special servicer of such commercial mortgage
        securities; provided, further, that CapitalSource shall not be entitled
        to choose the Special Servicer in connection with a Senior Participation
        Securitization or in the event that it does not purchase the
        Subordinated Securities as required by Section 4.03.

                (c) CSFB agrees to reasonably cooperate with CapitalSource in
CapitalSource's efforts to obtain the necessary approvals and ratings to enable
CapitalSource or an affiliate to act as servicer and special servicer of the
Securitizations.

                (i) If, prior to a Securitization, CapitalSource receives all
        such approvals and ratings, CSFB and CapitalSource agree that
        CapitalSource shall be retained as the servicer and/or special servicer
        for such Securitization and shall be compensated therefor at an annual
        rate consistent with then-market standards; provided, however, that
        CapitalSource shall not be retained as the servicer and/or special
        servicer in connection with a Senior Participation Securitization or in
        the event that it does not purchase the Subordinated Securities as
        required by Section 4.03. CapitalSource agrees to pay all expenses
        related to the process of obtaining the necessary approvals and ratings
        to enable it to act as servicer and special servicer of the
        Securitizations.

                (ii) If, prior to a Securitization, CapitalSource fails to
        receive all such approvals and ratings, CSFB and CapitalSource agree
        that any servicer or special servicer retained for such Securitization
        shall agree to retain CapitalSource as sub-servicer or sub-special
        servicer, as applicable.

                Section 4.10 Expenses. Each of CSFB and CapitalSource agrees to
pay (or cause to be paid) its pro rata share of the following expenses with
respect to each Securitization based on the proportion that the principal amount
of the Approved Loans that Column (in the case of CSFB) and CapitalSource
contributes to such Securitization bears to the total aggregate principal amount
of the Approved Loans included in such Securitization: (a) the reasonable fees,
disbursements and expenses of counsel to the CSFB Parties and counsel to
CapitalSource in connection with the issuance of the securities in such
Securitization and all other reasonable expenses in connection with the
preparation of the related offering document and closing documents (including
any compilations thereof) and any other documents in connection with the
offering, purchase, sale and delivery of such securities; (b) the reasonable
fees of accountants in connection with the issuance of such securities; (c) all
expenses in connection with the qualification of such securities, if any, for
offering and sale under state securities laws, including the fees and
disbursements of counsel in connection with such qualification and in connection
with Blue Sky and legal investment surveys; (d) the fees charged by the rating
agency or agencies for rating the securities or the Approved Loans proposed to
be included in such Securitization which ratings have been solicited by any CSFB
Party; (e) if CapitalSource is not the servicer or special servicer for such
Securitization, the reasonable up front fees and expenses of the servicer and/or
special servicer and the reasonable fees and disbursements of counsel for the
servicer and/or special servicer in connection with the preparation and review
of the transaction documents; (f) the reasonable up front fees and expenses of
any trustee and the


                                      -14-
<PAGE>

reasonable fees and disbursements of its counsel in connection with the
preparation and review of the transaction documents; (g) the fees of the
financial printer with respect to such Securitization; (h) any cost incurred in
connection with the designation of such securities for trading on PORTAL; and
(i) any additional fees or costs incurred by any CSFB Party in connection with
the purchase, sale and transfer of the Approved Loans to be included in such
Securitization. It is understood, however, that except as provided in this
Section 4.10 and in accordance with Section 4.11, each CSFB Party and
CapitalSource will pay all of its own costs and expenses with respect to each
Securitization; provided, however, that CapitalSource will pay all of the
reasonable loan due diligence expenses incurred by CSFB, including the
reasonable fees of counsel to any CSFB Party, in connection with the on-going
review of Approved Loans proposed to be included in such Securitization that
have not been originated by CSFB or an affiliate. CapitalSource agrees to pay
50% of all of the reasonable costs and expenses of CSFB, Repo Counterparty and
Column (including legal fees and expenses) in connection with the transactions
contemplated by this Agreement and the Repo Agreement (other than the
Securitizations).

        Section 4.11 Indemnification. With respect to each Securitization,
CapitalSource will indemnify the Depositor, CSFB and any co-underwriters against
losses, claims, damages or liabilities to which any such party may become
subject in connection with (i) misstatements or omissions from related
disclosure documents concerning the Approved Loans contributed by CapitalSource
to such Securitization, (ii) CapitalSource or (iii) any other information
provided by CapitalSource for inclusion in such disclosure documents, such
indemnity to be in a form that is customary in similar transactions.

        Section 4.12 Representations and Warranties with Respect to the Approved
Loans. As of the closing date of each Securitization, CapitalSource shall make
the representations and warranties concerning the mortgage loans being sold by
it to the Depositor substantially in the form set forth on Schedule 1 to the
Repo Agreement (subject to any necessary exceptions, which must be approved in
writing by CSFB), with any changes or additions to such representations and
warranties as the relevant rating agencies or investors may require. As of the
closing date of each Securitization, Column shall make the representations and
warranties concerning the loans being sold by it to the Depositor substantially
in the form set forth on Schedule 1 to the Repo Agreement (subject to any
necessary exceptions, which must be approved in writing by CSFB), with any
changes or additions to such representations and warranties as the relevant
rating agencies or investors may require.

        Section 4.13 Refinancing of Approved Loans. CSFB acknowledges that by
the terms of the transaction documents underlying Approved Loans originated by
CapitalSource, CapitalSource may have the right of first refusal to refinance
such Approved Loans. CapitalSource acknowledges that by the terms of the
transaction documents underlying Approved Loans originated by Column, Column may
have the right of first refusal to refinance such Approved Loans.
