RECITALS:

A. Credit Suisse First Boston Mortgage Capital LLC, a Delaware limited liability

B. The Loan is evidenced by that certain Deed of Trust Note, dated as of
December 23, 1997 (the “Note”), from Pledgor to Original Lender.

C. The Loan and Note are secured by those certain Deed of Trust, Assignment of
Leases and Rents and Security Agreements, each dated as of the date of the Note
(the “Deed of Trust”), executed by Pledgor in favor of Richard W. Klein, Jr., as
trustee (“Original Pledgee”) for the benefit of Original Lender, as Beneficiary,
granting to Original Pledgee, among other things, a lien on the real property
located at 6600 Business Parkway, Elkridge, Maryland, 250 Exchange Place,

D. Original Lender assigned all of its right, title and interest in the Loan,
and the Loan Documents to Pledgee.

E. Pursuant to the Loan Documents, Pledgor has requested that Pledgee release
the lien of the Deed of Trust and terminate the Collateral Documents upon
Pledgor’s defeasance of the Loan.

F. Pursuant to the Loan Documents, it is a condition precedent to Pledgee’s
obligation to release the lien of the Deed of Trust and terminate the Collateral
Documents that Pledgor grant a security interest in the Pledged Collateral (as
defined in the Security Agreement) to Pledgee to secure the payment and
performance in full when due of all amounts payable under the Loan Documents.

granted to Pledgee, pursuant to a certain Defeasance Pledge and Security
Agreement, dated as of the date hereof, by and among Pledgor, Pledgee, Servicer
and acknowledged by Intermediary (the “Security Agreement”), a security interest
in the Securities, certain other collateral and the proceeds thereof to secure
the payment and performance in full when due of all amounts payable under the
Loan Documents.

H. In connection with the Security Agreement, Pledgor, Pledgee, Intermediary and
Servicer have entered into the Defeasance Account Agreement, pursuant to which
Intermediary has established and will maintain an account to hold the Pledgor’s
interest in the Securities and other collateral.

I. In connection with Pledgee’s release of the lien of the Deed of Trust and
termination of the Collateral Documents pursuant to the Loan Documents, Pledgor
is required or permitted to transfer and assign all obligations, rights and
duties under and to the Note and the other Defeasance Documents, together with
its interest in the Pledged Collateral, to a successor entity established or
designated in accordance with the Loan Documents.

J. Successor Borrower has been established or designated to be the successor
entity to assume certain of Pledgor’s rights and obligations under the
Defeasance Documents, and Servicer, acting on behalf of Pledgee, has approved
Successor Borrower to be the successor entity to assume certain of Pledgor’s
rights and obligations under the Defeasance Documents.

K. Pledgor desires to (i) obtain the release of the lien of the Deed of Trust
and terminate the Collateral Documents, (ii) transfer certain of its rights and
obligations under the Defeasance Documents to Successor Borrower and
(iii) obtain a release of certain of its rights and obligations under the
Defeasance Documents and the other Loan Documents to the extent provided herein,
and Successor Borrower desires to assume certain of Pledgor’s rights and
obligations under the Defeasance Documents and acquire Pledgor’s right, title
and interest in the Pledged Collateral.

NOW, THEREFORE, in consideration of the mutual covenants and promises of the
parties hereto and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

Section 1. Definitions.

Each capitalized term used and not defined herein shall have the meaning
assigned to such term in the Security Agreement.

Section 2. Assignment of Secured Obligations and Securities.

Pledgor hereby sells, transfers and assigns to Successor Borrower, effective as
of the date hereof, (a) the Secured Obligations including, without limitation,
all obligations, rights and duties in, to and under, and subject to the terms
of, the Defeasance Documents and (b) all of Pledgor’s right, title and interest
in and to the Pledged Collateral, subject to the terms of the Defeasance
Documents and to the rights of Pledgee and the obligations of Intermediary
pursuant to the Security Agreement and the Defeasance Account Agreement.

Section 3. Assumption of Loan Obligations.

(a) Successor Borrower, for good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, hereby assumes, and agrees to be
bound by and to perform: (1) each of the Secured Obligations and all other
covenants, agreements, representations and warranties of Pledgor under the
Defeasance Documents, first arising or accruing on or after the Closing Date,
and (2) each of the obligations, covenants, agreements, representations and
warranties of Successor Borrower contained herein (the failure to comply with
Section 3(a)(1) or Section 3(a)(2) shall constitute an Event of Default);
provided however, Successor Borrower shall not assume any obligations (i) under
Section 4 of the Security Agreement (with respect to the Securities transferred
to Successor Borrower on the date hereof), (ii) under Section 6 of the Security
Agreement, to the extent that such obligations have been fully performed by
Pledgor or parties other than Successor Borrower prior to the transfer of the
Securities to Successor Borrower, (iii) that may arise as a result of the
Pledgor’s failure to effect the initial perfection of Pledgee’s interest in the
Pledged Collateral prior to the transfer of the Pledged Collateral to Successor
Borrower, (iv) that may arise as a result of any misrepresentation or
misstatement made by Pledgor in any of the Defeasance Documents or otherwise
made by Pledgor in connection with the defeasance transaction contemplated under
this Agreement or (v) arising under the Note or other Loan Documents (to the
extent that such Loan Documents are incorporated in the Note), which (1) relate
to the use or operation of the Real Property or (2) conflict with any express
covenants or obligations assumed by Successor Borrower under the other
Defeasance Documents; provided, further, however, except as otherwise expressly
provided in Section 3(b) below, Successor Borrower shall be liable to Pledgee
only to the extent of the Pledged Collateral, and Pledgee shall have no recourse
against, and Pledgee shall not enforce any monetary judgment against, assets of
Successor Borrower other than the Pledged Collateral, with respect to the
Secured Obligations. Nothing herein is intended to limit or restrict Pledgee’s
rights or remedies with respect to the Pledged Collateral.

(b) Notwithstanding the foregoing, Successor Borrower (but not its members or
manager) shall be personally liable for all claims, demands, liabilities,
deficiencies, losses, damages, judgments, costs, and expenses, including without
limitation reasonable attorneys fees and costs of collection incurred, suffered
or paid by Pledgee as a result of:

(i) any representation, warranty or certification made by or on behalf of
Successor Borrower for the benefit of Pledgee in any Defeasance Document (or in
any modification or supplement thereto), or in any certificate, report,
financial statement or other item furnished to Pledgee in connection with this
transaction having been false or misleading in any material respect as of the
time made or furnished;

(ii) the Pledged Collateral or any part thereof or interest therein becoming
subject to any security interest, pledge, covenant, lien, or other encumbrance
whether junior or senior to the interest of Pledgee as a result of actions of
Successor Borrower;

(iii) the Pledged Collateral or any part thereof or interest therein being sold,
assigned, transferred, conveyed or otherwise disposed of, or becoming the
subject of any attempted sale, assignment, transfer or conveyance, by Successor
Borrower;

(iv) any of the Events of Default described in subparagraphs (vii), (viii),
(ix), (x), (xi) or (xii) of Section 9(a) of the Security Agreement shall occur
as a result of actions of Successor Borrower or circumstances relating to
Successor Borrower;

(v) Successor Borrower’s failure at any time to be a Single Purpose Entity in
good standing in the jurisdiction of its formation and primary place of
business; or

(vi) the funds in the Pledged Collateral Account being insufficient to satisfy
all obligations due under the Note or under any other Defeasance Document
(without taking into account (a) reinvestment income or (b) failure by any
Obligor to satisfy its obligations under the Securities).

Successor Borrower’s assumption of the obligations of Pledgor as set forth above
under the Defeasance Documents other than the Note is limited to those
obligations arising on and after the date hereof. With respect to the Note,
Successor Borrower expressly assumes liability for the outstanding principal
balance of the Loan as of the date hereof and all interest accruing on the Loan
from the first day of the interest accrual period in which the defeasance
contemplated herein occurs, which shall be paid from Pledged Collateral
deposited by the Pledgor into the Pledged Collateral Account in accordance with
the provisions of the Defeasance Account Agreement. Successor Borrower
acknowledges that Section 57(d) of the Deed of Trust states that the Loan may
not be prepaid following the consummation of the Defeasance and the release of
the Real Property.

(c) Notwithstanding anything to the contrary set forth in Section 3(b), Pledgee
shall have no recourse for any claims, demands, liabilities, deficiencies,
losses, damages, judgments, costs and expenses, including, without limitation,
legal fees and expenses, under Section 3(b) or otherwise under the Defeasance
Documents against any assets (other than the Pledged Collateral) of Successor
Borrower that have been pledged to Pledgee pursuant to any other defeasance
transaction until such transaction has been paid in full pursuant to which
Successor Borrower becomes the successor borrower under one or more defeased
mortgage loans held by Pledgee.

(d) In addition to the rights of Pledgee under the Defeasance Documents,
Successor Borrower hereby grants to Pledgee and Servicer a power of attorney to
file, at Successor Borrower’s cost, any franchise or other administrative
filings which may be required to maintain Successor Borrower’s good standing and
legal existence in the event Successor Borrower fails to do so and such failure
continues for thirty (30) days after written notice.

(e) Successor Borrower shall deliver to Pledgee, within thirty (30) days after
written request from Pledgee, certification signed by an officer of Successor
Borrower or of Successor Borrower’s managing member or general partner, as
applicable, certifying that such officer is familiar with the activities and
operations of Successor Borrower and Successor Borrower’s affiliates and all
transactions entered into by Successor Borrower during the preceding twelve
months (or since the date of Successor Borrower’s formation, if Successor
Borrower was formed during such preceding twelve month period), and that, to
such officer’s knowledge, Successor Borrower has conducted itself as a Single
Purpose Entity during such period, has filed all tax returns required to be
filed during such period and has paid all taxes due and payable during such
period. If requested by Pledgee, each such certification shall be accompanied by
an original certificate of existence or good standing issued by the Secretary of
State of the jurisdiction of Successor Borrower’s formation dated not more than
thirty (30) days prior to date of such certification. In addition to any other
remedies that Pledgee may have under the Defeasance Documents, in the event of
the failure of Successor Borrower to maintain its status as a Single Purpose
Entity in good standing, Successor Borrower’s failure to file all required tax
returns and pay all taxes that it owes or Successor Borrower’s failure to file
all forms and documents required to maintain its separate legal existence, in
each case, which failure shall continue for thirty (30) days after written
notice, Successor Borrower hereby agrees to the assumption of the Loan by, and
the transfer of the Pledged Collateral to, a Single Purpose Entity designated by
Pledgee and hereby appoints Pledgee and Servicer as attorneys-in-fact with power
of attorney to affect such transfer and assumption.

Section 4. Acknowledgment of Pledgee.

Subject to the satisfaction, or written waiver, of all conditions to defeasance
set forth in the Loan Documents, Pledgee hereby consents to (a) and shall
promptly release the Real Property from the lien of the Deed of Trust, and
terminate the Collateral Documents, (b) the transfer of Pledgor’s rights in the
Pledged Collateral and rights and obligations under the Defeasance Documents to
Successor Borrower and (c) the assumption in accordance with Section 3 of
Pledgor’s rights, title and interest in the Pledged Collateral and Pledgor’s
rights and obligations under the Defeasance Documents by Successor Borrower and
Pledgee hereby acknowledges that nothing in this Agreement or the other
Defeasance Documents shall be construed as an agreement on the part of Successor
Borrower to assume or be liable for any claim, liabilities or obligations under
the Loan Documents other than those claims, liabilities and obligations under
the Note and the claims, liabilities and obligations under the other Defeasance
Documents first arising or accruing on or after the Closing Date.

Section 5. Release of Pledgor.

Subject to satisfaction, or written waiver, of all conditions to defeasance set
forth in the Loan Documents and, if applicable, confirmation from each of the
Rating Agencies that the transactions contemplated by the Defeasance Documents
will not result in a downgrade, qualification or withdrawal of the current
rating of any of the Certificates or a failure to satisfy the criteria for
defeasances established by each of the Rating Agencies, Pledgee hereby releases
and discharges Pledgor from all claims, liabilities and obligations under the
Loan Documents and the Defeasance Documents related to events first occurring or
arising after the Closing Date, provided, however, Pledgor shall not be released
from liability for any loss or damages suffered, or expenses incurred, by

Agreement;

report, financial statement or other item delivered by or on behalf of Pledgor
in connection therewith that proves to have been false or misleading in any
material respect when made or delivered;

(iii) arising as a result of the transfer of, or creation and perfection of the
first priority lien on, the Pledged Collateral being deemed void or voidable for
any reason whatsoever or any other payment made by Pledgor in respect of amounts
due under the Loan Documents on or prior to the date hereof being recovered from
Pledgee by Pledgor, its creditors, or any other person for any reason
whatsoever;

(iv) for any other failure to pledge the Pledged Collateral to Pledgee or take
any action necessary to effect the initial first priority perfection of
Pledgee’s security interest therein or to effectively transfer the Pledged
Collateral to Successor Borrower in accordance with the Defeasance Documents;

(v) arising under the Environmental Indemnity Agreement, dated December 23,
1997, among Pledgor and Original Lender or similar instruments executed by

terms, survive the release of the lien of the Deed of Trust;

claims, causes of action and liabilities relating directly or indirectly to the
Loan, the Real Property, the Loan Documents and the closing of the defeasance
transaction contemplated by the Defeasance Documents, arising on or prior to the
