          The Securities Administrator agrees that if any of the events specified in clauses (ii) or (iii) of this
Section 9(c) shall occur, it shall give written notice thereof to the Issuer and the Indenture Trustee within
seven days after the occurrence of such event.

         (d)      No resignation or removal of the Securities Administrator pursuant to this Section 9 shall be

with the Sale and Servicing Agreement and (ii) such successor Securities Administrator shall have agreed in
writing to be bound by the terms of this Agreement in the same manner as the Securities Administrator is bound
hereunder.

may petition any court of competent jurisdiction for the appointment of a successor Securities Administrator.

         (e)      The appointment of any successor Securities Administrator shall be effective only after receipt

upon the appointment of a successor Master Servicer pursuant to the Sale and Servicing Agreement, the Securities
Administrator shall immediately resign and such successor Master Servicer shall automatically become the
Securities Administrator under this Agreement.  Any such successor Master Servicer shall be required to agree to
assume the duties of the Securities Administrator under the terms and conditions of this Agreement in its
acceptance of appointment as successor Master Servicer.

         Section 10.  Action upon Termination, Resignation or Removal of the Securities Administrator.  Promptly

such termination, resignation or removal.  The Securities Administrator shall forthwith upon such termination
pursuant to Section 9 deliver to the successor Securities Administrator all property and documents of or relating
to the Collateral then in the custody of the Securities Administrator, or if this Agreement has been terminated,
to the Depositor.  In the event of the resignation or removal of the Securities Administrator pursuant to
Section 9, the Securities Administrator shall cooperate with the Issuer and take all reasonable steps requested to
assist the Issuer in making an orderly transfer of the duties of the Securities Administrator.

         Section 11.  Reporting Requirements of the Commission.  The Securities Administrator shall provide the
required assessments, attestations and reports and otherwise comply with Sections 3.16, 3.17, 3.18 and 3.19 of

          Section 13.  Amendments.

         (a)      This Agreement may be amended from time to time by the parties hereto, without notice to or the
consent of any of the Holders, (i) to cure any ambiguity, (ii) to cause the provisions herein to conform to or be
consistent with or in furtherance of the statements made with respect to the Securities, the Trust or this
Agreement in any Offering Document, or to correct or supplement any provision herein which may be inconsistent
with any other provisions herein, (iii) to make any other provisions with respect to matters or questions arising
under this Agreement or (iv) to add, delete, or amend any provisions to the extent necessary or desirable to
comply with any requirements imposed by the Code.  No such amendment effected pursuant to clause (iii) of the
preceding sentence may adversely affect in any material respect the interests of any Holder.  Prior to entering
into any amendment without the consent of Holders pursuant to this paragraph, the Securities Administrator may
require an Opinion of Counsel (at the expense of the party requesting such amendment) to the effect that such
amendment is permitted under this paragraph.  Any such amendment shall be deemed not to adversely affect in any
material respect any Holder if the Securities Administrator receives (i) written confirmation from the Rating
Agencies that such amendment will not cause the Rating Agencies to withdraw, qualify or reduce the then current
rating assigned to the Notes or (ii) an Opinion of Counsel to such effect.

         (b)      This Agreement may also be amended from time to time by the parties hereto with the consent of
the Majority Securityholders for the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement or of modifying in any manner the rights of the Holders; provided,
however, that no such amendment may (i) increase or reduce in any manner the amount of, or accelerate or delay
the timing of, collections of payments on the Collateral or distributions that shall be required to be made for
the benefit of the Noteholders or the Certificateholders or (ii) reduce the aforesaid percentage of the Class
Principal Amount (or Class Notional Amount) of the Notes of any Class required to consent to any such amendment
without the consent of the Holders of all the outstanding Securities.

         (c)      Promptly after the execution of any such amendment, the Securities Administrator shall furnish
a copy of such amendment to each Holder, the Depositor and to each Rating Agency.

         (d)      It shall not be necessary for the consent of Holders under this Section 13 to approve the
particular form of any proposed amendment, but it shall be sufficient if such consent shall approve the substance
thereof.  The manner of obtaining such consents and of evidencing the authorization of the execution thereof by
Holders shall be subject to such reasonable regulations as the Securities Administrator may prescribe.

         (e)      The Owner Trustee, the Trust and the Securities Administrator may, but shall not be obligated
to, enter into any amendment which affects the Owner Trustee's or the Securities Administrator's respective
rights, duties or immunities under this Agreement or otherwise.

         Section 14.  Successors and Assigns.  This Agreement may not be assigned by the Securities Administrator
unless such assignment is previously consented to in writing by the Owner Trustee and the Depositor, and the

 if accepted by the assignee, shall bind the assignee hereunder in the same manner as the Securities Administrator
is bound hereunder.  Notwithstanding the foregoing, this Agreement may be assigned by the Securities
Administrator without the consent of the Owner Trustee or the Depositor to a corporation or other organization
that is a successor (by merger, consolidation or purchase of assets) to the Securities Administrator, provided
that such successor organization executes and delivers to the Issuer, the Owner Trustee and the Depositor an
agreement in which such corporation or other organization agrees to be bound hereunder by the terms of said
assignment in the same manner as the Securities Administrator is bound hereunder.  Subject to the foregoing, this
Agreement shall bind any successors or assigns of the parties hereto.

         Section 15.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTION 5-1401 OF
THE GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

         Section 16.  Headings.  The Section headings hereof have been inserted for convenience of reference only
and shall not be construed to affect the meaning, construction or effect of this Agreement.

         Section 17.  Counterparts.  This Agreement may be executed in counterparts, each of which when so
executed shall together constitute one and the same agreement.

         Section 18.  Severability.  Any provision of this Agreement that is prohibited or unenforceable in any
jurisdiction shall be ineffective to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof and any such prohibition or unenforceability in any jurisdiction shall not invalidate
or render unenforceable such provision in any other jurisdiction.

         Section 19.  Not Applicable to Wells Fargo Bank, N.A. in Other Capacities.  Nothing in this Agreement
shall affect any obligation Wells Fargo Bank, N.A. may have in any other capacity.

         Section 20.  Limitation of Liability of Owner Trustee.  Notwithstanding anything contained herein to the
contrary, this Agreement has been executed by LaSalle National Trust Delaware not in its individual capacity but
solely in its capacity as Owner Trustee of the Issuer and in no event shall LaSalle National Trust Delaware in
its individual capacity or any beneficial owner of the Issuer have any liability for the representations,
warranties, covenants, agreements or other obligations of the Issuer hereunder, as to all of which recourse shall
be had solely to the assets of the Issuer.  For all purposes of this Agreement, in the performance of any duties
or obligations of the Issuer hereunder, the Owner Trustee shall be subject to, and entitled to the benefits of,
the terms and provisions of Articles VI, VII and VIII of the Trust Agreement.

         Section 21.  Limitation of Liability of the Securities Administrator; Indemnification.  Notwithstanding
anything herein to the contrary, this Agreement has been signed by Wells Fargo Bank, N.A. not in its individual

capacity but solely in its capacity as Securities Administrator and in no event shall the Securities
Administrator in its individual capacity have any liability for the representations, warranties, covenants,
agreements or other obligations of the Issuer hereunder, as to all of which recourse shall be had solely to the
assets of the Issuer.  The Securities Administrator shall not have any duties or obligations other than those
expressly set forth in this Agreement, and no implied duties on its part shall be read into this Agreement.  In
acting as Securities Administrator, Wells Fargo Bank, N.A. shall be entitled to the same benefits, rights,
immunities, protections and rights to indemnification as are afforded to the Indenture Trustee under Article Six
(including without limitation Section 6.07) of the Indenture.

         Section 22.  Benefit of Agreement.  It is expressly agreed that in performing its duties under this
Agreement, the Securities Administrator will act for the benefit of holders of the Securities as well as for the
benefit of the Issuer, and that such obligations on the part of the Securities Administrator shall be enforceable
at the instance of the Indenture Trustee, the Owner Trustee and the Issuer.

         Section 23.  Bankruptcy Matters.  No party to this Agreement shall take any action to cause the
Depositor or the Issuer to dissolve in whole or in part or file a voluntary petition or otherwise initiate
proceedings to have the Depositor or the Issuer adjudicated bankrupt or insolvent, or consent to the institution
of bankruptcy or insolvency proceedings against the Depositor or the Issuer, or file a petition seeking or
consenting to reorganization or relief of the Depositor or the Issuer as debtor under any applicable federal or
state law relating to bankruptcy, insolvency, or other relief for debtors with respect to the Depositor or the
Issuer; or seek or consent to the appointment of any trustee, receiver, conservator, assignee, sequestrator,
custodian, liquidator (or other similar official) of the Depositor or the Issuer or of all or any substantial
part of the properties and assets of the Depositor or the Issuer, or cause the Issuer to make any general
assignment for the benefit of creditors of the Depositor or the Issuer, or take any action in furtherance of any
of the above actions.
