                         REPRESENTATIONS AND WARRANTIES

     Lessee represents and warrants that, except as otherwise disclosed to or
known by Lender as of the date of hereof:

     Section 3.1 Validity of Security Agreement; Consents. The execution,
                 ----------------------------------------
delivery and performance of this Security Agreement and the creation of the
security interests provided for herein (i) do not violate any law or regulation
or any order or decree of any court or governmental instrumentality applicable
to Lessee, (ii) do not conflict with or result in a breach of, or constitute a
default under, any indenture, mortgage, deed of trust, lease, agreement or other
instrument to which Lessee is a party or by which it or any of its properties is
bound, (iii) do not result in the creation or imposition of any lien upon any
property of Lessee other than in favor of Lender, and (iv) do not require the
consent or approval of any governmental body, agency or official or other person
other than those that have been obtained. This Security Agreement has been duly
executed and delivered by Lessee and constitutes the legal, valid and binding
obligation of Lessee, enforceable against it in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to or affecting
the enforceability of creditors' rights generally and by general provisions of
equity (regardless of whether such enforceability is considered in a proceeding
in equity or at law).

     Section 3.2 Title to Collateral. Except for the security interests granted
                 -------------------
to Lender pursuant to this Security Agreement and the other Loan Documents,
Lessee holds a leasehold interest in each item of the Collateral, having good
and marketable title thereto, free and clear of any and all liens, encumbrances,
security interests and claims of others. Lessee expressly acknowledges and
agrees that Lessee's interest in and to the Collateral is expressly subject to
the liens, security titles and security interests in favor of Lender pursuant to
the Loan Documents

                                        9

<PAGE>

previously executed and delivered by Borrower and that this Security Agreement
is given to Lender in furtherance thereof. Lessee further acknowledges and
agrees that all revenues generated by the Mortgaged Property shall be remitted
by Residence Inn By Marriott, Inc. in accordance with the terms of the Four
Party Agreement.

     Section 3.3 Validity, Perfection and Priority of Security Interests.
                 -------------------------------------------------------

          (a) By complying with Section 4.1, Lessee will have created a valid
security interest in favor of Lender in Lessee's interest in all existing
Collateral and in all identifiable proceeds of such Collateral, which security
interest (except in respect of motor vehicles for which the exclusive manner of
perfecting a security interest therein is by noting such security interest on
the certificate of title in accordance with local law) would be prior to the
claims of a trustee in bankruptcy under Section 544(a) of the United States
Bankruptcy Code. Continuing compliance by Lessee with the provisions of Section
4.2 will also (i) create valid security interests in Lessee's interest in all
Collateral acquired after the date hereof and in all identifiable proceeds of
such Collateral and, (ii) cause such security interests in all Collateral and in
all proceeds which are (A) identifiable cash proceeds of Collateral covered by
financing statements required to be filed hereunder, and (B) identifiable
proceeds in which a security interest may be perfected by such filing under the
UCC.

          (b) Lessee has not granted a security interest in any of the
Collateral to any person other than Lender. Other than financing statements or
other similar documents perfecting the security interests or deed of trust liens
of Lender, no financing statements, deeds of trust, mortgages or similar
documents covering all or any part of the Collateral are on file or of record in
any government office in any jurisdiction in which such filing or recording
would be effective to perfect a security interest in such Collateral, nor is any
of the Collateral in the possession of any person (other than Lessee) asserting
any claim thereto or security interest therein.

following.

                 --------------------------------

to the Collateral or any portion thereof in such jurisdictions as Lender may

by Lessee under this Security Agreement or any other Loan Document, and such
financing statements may contain, among other items as Lender may deem advisable
to include therein, the federal tax identification number of Lessee, and may
describe the property covered by such financing statements as "all assets of
Lessee," "all personal property of Lessee" or words of similar effect.

     Section 4.2 Further Actions.
                 ---------------

          (a) Lessee will, from time to time and at its expense, execute,
deliver, file or record such financing statements pursuant to the Uniform
Commercial Code, applications for certificates of title and such other
statements, assignments, instruments, documents, agreements or other papers and
take any other action that Lender may reasonably request, in order to create,
preserve, perfect, confirm or validate the security interests, to enable Lender
to obtain the full benefits of this Security Agreement or to enable it to
exercise and enforce any of its rights, powers and remedies hereunder,
including, without limitation, its right to take possession of the Collateral,
and will use its best efforts to obtain such waivers from landlords and
mortgagees as Lender may request.

          (b) Lessee will not merge or consolidate into, or transfer of any of
the Collateral to, any other person or entity without the prior written consent
of Lender.

          (c) Lessee shall not change its name unless it has given Lender thirty
(30) days' prior written notice thereof

          (d) Lessee shall, at any time and from time to time, whether or not
the Official Text of Revised Article 9, 2000 Revision, of the Uniform Commercial
Code promulgated by the American Law Institute and the National Conference of
Commissioners on Uniform State Laws or a version thereof ("UCC Revised Article
9") is in effect in any particular jurisdiction, take such steps as Lender may
reasonably request for Lender (A) to obtain an acknowledgment, in form and
substance reasonably satisfactory to Lender, of any bailee having possession of
any of the Mortgaged Property, stating that the bailee holds possession of such
Mortgaged Property on behalf of Lender, (B) to obtain "control" of any
investment property, deposit accounts, letter-of-credit rights, or electronic
chattel paper (as such terms are defined by UCC Revised Article 9 with
corresponding provisions thereof defining what constitutes "control" for such
items of collateral), with any agreements establishing control to be in form and
substance reasonably satisfactory to Lender, and (C) otherwise to insure the
continued perfection and priority of the Lender's security interest in any of
the Collateral and of the preservation of its rights therein,

                                       11

<PAGE>

whether in anticipation of or following the effectiveness of UCC Revised Article
9 in any jurisdiction. If Lessee shall at any time, whether or not UCC Revised
Article 9 is in effect in any particular jurisdiction, acquire a "commercial
tort claim" (as such term is defined in UCC Revised Article 9 with respect to
the Collateral or any portion thereof) Lessee shall promptly notify Lender
thereof in writing, providing a reasonable description and summary thereof, and
shall execute a supplement to this Security Agreement in form and substance
acceptable to Lender granting a security interest in such commercial tort claim
to Lender.

     Section 4.3 Change of Name, Identity or Structure. Lessee will not change
                 -------------------------------------
its name, will not conduct its business under any trade, assumed or fictitious
name unless it shall have given Lender at least thirty (30) days' prior written
notice thereof and executed or authorized, at the request of Lender, such
additional financing statements to be filed in such jurisdictions as Lender may
deem necessary or desirable in its sole discretion.

     Section 4.4 Maintenance of Records. Lessee will keep and maintain at its
                 ----------------------
own cost and expense complete books and records relating to the Collateral which
are satisfactory to Lender including, without limitation, a record of all
payments received and all credits granted with respect to the Collateral and all
of its other dealings with the Collateral. Lessee will mark its books and
records pertaining to the Collateral to evidence this Security Agreement and the
security interests granted hereby. For Lender's further security, Lessee agrees
that Lender shall have a special property interest in all of Lessee's books and
records pertaining to the Collateral and Lessee shall deliver and turn over any
such books and records, or copies thereof, to Lender or to its representatives
at any time on demand of the Lender.

     Section 4.5 Compliance with Laws, etc. Lessee will comply, in all material
                 -------------------------
respects, with all acts, rules, regulations, orders, decrees and directions of
any governmental body, agency or official applicable to the Collateral or any
part thereof or to the operation of the Mortgaged Property except to the extent
that the failure to comply would not have a material adverse effect on the
financial or other condition of the Mortgaged Property; provided, however, that
Lessee may contest any act, regulation, order, decree or direction in any
reasonable manner which shall not in the sole opinion of Lender adversely affect
Lender's rights or the first priority of its security interest in the
Collateral.

     Section 4.6 Payment of Taxes, etc. Lessee will pay promptly when due, all
                 ---------------------
taxes, assessments and governmental charges or levies imposed upon the
Collateral or in respect of its income or profits therefrom, as well as all
claims of any kind (including claims for labor, materials and supplies), except
that no such charge need be paid if (i) the validity thereof is being contested
in good faith by appropriate proceedings, and (ii) such charge is adequately
reserved against in accordance with generally accepted accounting principals,
consistently applied.

     Section 4.7 Compliance with Terms of Accounts, Contracts and Licenses.
                 ---------------------------------------------------------
Lessee will perform and comply in all material respects with all of its
obligations under and, all agreements relating to the Collateral to which it is
a party or by which it is bound.

     Section 4.8 Limitation on Liens on Collateral. Except as to any liens now
                 ---------------------------------
in existence and known to Lender, Lessee will not create, permit or suffer to
exist, and will defend the Collateral and Lessee's rights with respect thereto
against and take such other action as is

                                       12

<PAGE>

necessary to remove, any Lien, security interest, encumbrance, or claim in or to
the Collateral other than the security interests created hereunder.

     Section 4.9 Limitations on Modifications of Accounts and Intangibles; No
                 ------------------------------------------------------------
Waivers or Extensions . Lessee will not amend, modify, terminate or waive any
---------------------
provision of any material receivable or other intangible in any manner which
might have a materially adverse effect on the value of such receivable or other
intangible as Collateral other than in the ordinary course of business. Lessee
will not, without Lender's prior written consent, grant any extension of the
time of payment of any material receivable or amounts due under any material
other intangible, compromise, compound or settle the same for less than the full
amount thereof, release, wholly or partly, any person liable for the payment
thereof or allow any credit or discount whatsoever thereon other than trade
discounts granted in the normal course of business, except such as in the
reasonable judgment of Lessee are advisable to enhance the collectability
thereof.

     Section 4.10 Limitations on Dispositions of Collateral. Lessee will not
                  -----------------------------------------
directly or indirectly (through the sale of stock, merger or otherwise) without
the prior written consent of Lender sell, transfer, lease or otherwise dispose
of any of the Collateral, or attempt, offer or contract to do so except for
sales of Inventory in the ordinary course of its business for fair value in
arm's-length transactions. The inclusion of proceeds of the Collateral under the
security interests granted hereby shall not be deemed a consent by Lender to any
sale or disposition of any Collateral other than as permitted by this Section
4.10.

     Section 4.11 Right of Inspection. Lender shall at all times have full and
                  -------------------
free access during normal business hours to all the books, correspondence and
records of Lessee related to the Mortgaged Property, and Lender or its
representatives may examine the same, take extracts therefrom, make photocopies
thereof and have such discussions with officers, employees and public
accountants of Lessee as Lender may deem necessary, and Lessee agrees to render
to Lender, at Lessee's cost and expense, such clerical and other assistance as
may be reasonably requested with regard thereto. Lender and its representatives
shall at all times also have the right to enter into and upon any premises where
any of the Inventory is located for the purpose of inspecting the same,
observing its use or protecting interests of Lender therein.

                                    ARTICLE V
                          REMEDIES; RIGHTS UPON DEFAULT

     Section 5.1 UCC Rights. If any Event of Default shall have occurred, Lender
                 ----------
may in addition to all other rights and remedies granted to it in this Security
Agreement and in any other instrument or agreement securing, evidencing or
relating to the Obligations, exercise all rights and remedies of a secured party
under the UCC and all other rights available to Lender at law or in equity.

     Section 5.2 Payments on Collateral. Without limiting the rights of Lender
                 ----------------------
under any other provision of the Security Agreement, if an Event of Default
shall occur and be continuing:

          (a) all payments received by Lessee under or in connection with any of
the Collateral shall be held by Lessee in trust for Lender, shall be segregated
from other funds of Lessee and shall forthwith upon receipt by Lessee be turned
over to Lender, in the same form as

                                       13

<PAGE>

received by Lessee (duly indorsed by Lessee to Lender, if required to permit
collection thereof by Lender); and

          (b) all such payments received by Lender (whether from Lessee or
otherwise) shall be applied in accordance with the terms and provisions of the
Loan Documents.

     Section 5.3 Possession of Collateral. In furtherance of the foregoing,
                 ------------------------
Lessee expressly agrees that, if an Event of Default shall occur and be
continuing, Lender may (i) by judicial powers, or without judicial process if it
can be done without breach of the peace, enter any premises where any of such
Collateral is or may be located, and without charge or liability to Lender seize
and remove such Collateral from such premises and (ii) have access to and use of
Lessee's books and records relating to such Collateral.

     Section 5.4 Sale of Collateral.
                 ------------------

          (a) Lessee expressly agrees that if an Event of Default shall occur
and be continuing, Lender, without demand of performance or other demand or
notice of any kind (except the notice specified below of the time and place of
any public or private sale) to Lessee or any other person (all of which demands
and/or notices are hereby waived by Lessee), may forthwith collect, receive,
appropriate and realize upon the Collateral and/or forthwith sell, lease,
assign, give an option or options to purchase or otherwise dispose of and
deliver the Collateral (or contract to do so) or any part thereof in one or more
parcels at public or private sale, at any exchange, broker's board or at any
office of Lender or elsewhere in such manner as is commercially reasonable and
as Lender may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. Lender shall have the right upon any such public
sale, and, to the extent permitted by law, upon any such private sale, to
purchase the whole or any part of the Collateral so sold. Lessee further agrees,
at Lender's request, to assemble the Collateral, and to make it available to
Lender at places which Lender may reasonably select. To the extent permitted by
applicable law, Lessee waives all claims, damages and demands against Lender
arising out of the foreclosure, repossession, retention or sale of the
Collateral.

          (b) Unless the Collateral threatens to decline speedily in value or is
of a type customarily sold in a recognized market, Lender shall give Lessee ten
days written notice of its intention to make any such public or private sale or
sale at a broker's board or on a securities exchange. Such notice shall (i) in
the case of a public sale, state the time and place fixed for such sale, (ii) in
the case of a sale at a broker's board or on a securities exchange, state the
board or exchange at which such sale is to be made and the day on which the
Collateral, or any portion thereof being sold, will first be offered for sale,
and (iii) in the case of a private sale, state the day after which such sale may
be consummated. Lender shall not be required or obligated to make any such sale
pursuant to any such notice. Lender may adjourn any public or private sale or
cause the same to be adjourned from time to time by announcement at the time and
place fixed for the sale, and such sale may be made at any time or place to
which the same may be so adjourned. In the case of any sale of all or any part
of the Collateral for credit or for future delivery, the Collateral so sold may
be retained by Lender until the selling price is paid by the purchaser thereof,
but Lender shall not incur any liability in case of failure of such purchaser to
pay for the Collateral so sold and, in the case of such failure, such Collateral
may again be sold upon like notice.

                                       14

<PAGE>

     Section 5.5 Rights of Purchasers. Upon any sale of the Collateral (whether
                 --------------------
public or private), Lender shall have the right to deliver, assign and transfer
to the purchaser thereof the Collateral so sold. Each purchaser (including
Lender) at any such sale shall hold the Collateral so sold free from any claim
or right of whatever kind, including any equity or right of redemption of
Lessee, and Lessee, to the extent permitted by law, hereby specifically waives
all rights of redemption, including, without limitation, the right to redeem the
Collateral under Section 9-506 of the UCC, and any right to a judicial or other
stay or approval which it has or may have under any law now existing or
hereafter adopted.

     Section 5.6 Additional Rights of Lender.
                 ---------------------------

          (a) Lender shall have the right and power to institute and maintain
such suits and proceedings as it may deem appropriate to protect and enforce the
rights vested in it by this Security Agreement and may proceed by suit or suits
at law or in equity to enforce such rights and to foreclose upon and sell the
Collateral or any part thereof pursuant to the judgment or decree of a court of
competent jurisdiction.

          (b) Lender shall, to the extent permitted by law and without regard to
the solvency or insolvency at the time of any person then liable for the payment
of any of the Obligations or the then value of the Collateral, and without
requiring any bond from any party to such proceedings, be entitled to the
appointment of a special receiver or receivers (who may be Lender) for the
Collateral or any part thereof and for the rents, issues, tolls, profits,
royalties, revenues and other income therefrom, which receiver shall have such
powers as the court making such appointment shall confer, and to the entry of an
order directing that the rents, issues, tolls, profits, royalties, revenues and
other income of the property constituting the whole or any part of the
Collateral be segregated, sequestered and impounded for the benefit of Lender,
and Lessee irrevocably consents to the appointment of such receiver or receivers
and to the entry of such order.

     Section 5.7 Remedies Not Exclusive.
                 ----------------------

          (a) No remedy conferred upon or reserved to Lender in this Security
Agreement is intended to be exclusive of any other remedy or remedies, but every
such remedy shall be cumulative and shall be in addition to every other remedy
conferred herein or now or hereafter existing at law, in equity or by statute.

          (b) If Lender shall have proceeded to enforce any right, remedy or
power under this Security Agreement and the proceeding for the enforcement
thereof shall have been discontinued or abandoned for any reason or shall have
been determined adversely to Lender, Lessee and Lender shall, subject to any
determination in such proceeding, severally and respectively be restored to
their former positions and rights under this Security Agreement, and thereafter
all rights, remedies and powers of Lender shall continue as though no such
proceedings had been taken.

          (c) All rights of action under this Security Agreement may be enforced
by Lender without the possession of any instrument evidencing any Obligation or
the production thereof at any trial or other proceeding relative thereto, and
any suit or proceeding instituted by Lender shall be brought in its name and any
judgment shall be held as part of the Collateral.

     Section 5.8 Waiver and Estoppel.
                 -------------------

          (a) Lessee, to the extent it may lawfully do so, agrees that it will
not at any time in any manner whatsoever claim or take the benefit or advantage
of any appraisement, valuation, stay, extension, moratorium, turnover or
redemption law, or any law now or hereafter in force permitting it to direct the
order in which the Collateral shall be sold which may delay, prevent or
otherwise affect the performance or enforcement of this Security Agreement and
Lessee hereby waives the benefits or advantage of all such laws, and covenants
that it will not hinder, delay or impede the execution of any power granted to
Lender in this Security Agreement but will permit the execution of every such
power as though no such law were in force; provided that nothing contained in
this Section 5.8 shall be construed as a waiver of any rights of Lessee under
any applicable federal bankruptcy law.

          (b) Lessee, to the extent it may lawfully do so, on behalf of itself
and all who may claim through or under it, including without limitation any and
all subsequent creditors, vendees, assignees and lienors, waives and releases
all rights to demand or to have any marshaling of the Collateral upon any sale,
whether made under any power of sale granted herein or pursuant to judicial
proceedings or upon any foreclosure or any enforcement of this Security
Agreement and consents and agrees that all the Collateral may at any such sale
be offered and sold as an entirety.

          (c) Lessee, to the extent it may lawfully do so, waives presentment,
demand, protest and any notice of any kind (except notices explicitly required
hereunder) in connection with this Security Agreement and any action taken by
Lender with respect to the Collateral.

     Section 5.9 Power of Attorney. Lessee hereby irrevocably constitutes and
                 -----------------
appoints Lender, with full power of substitution, as its true and lawful
attorney-in-fact with full irrevocable power and authority in the place and
stead of Lessee and in the name of Lessee or in its own name, from time to time
in Lender's reasonable discretion for the purpose of carrying out the terms of
this Security Agreement, to take any and all appropriate action and to execute
any and all documents and instruments which may be necessary or desirable to
accomplish the purposes of this Security Agreement and, without limiting the
generality of the foregoing, hereby gives Lender the power and right, on behalf
of Lessee, without notice to or assent by Lessee to do the following:

          (a) to pay or discharge taxes, liens, security interests or other
encumbrances levied or placed on or threatened against the Collateral;

          (b) upon the occurrence and continuance of any Event of Default and
otherwise to the extent provided in this Security Agreement, (i) to direct any
party liable for any payment under any of the Collateral to make payment of any
and all moneys due and to come due thereunder directly to Lender or as Lender
shall direct; (ii) to receive payment of and receipt for any and all moneys,
claims and other amounts due and to become due at any time in respect of or
arising out of any Collateral; (iii) to sign and indorse any invoices, freight
or express bills, bills of lading, storage or warehouse receipts, drafts against
debtors, assignments, verifications and notices in connection with accounts and
other documents relating to the Collateral; (iv) to commence and prosecute any
suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect the Collateral or any thereof and to enforce any other
right in

                                       16

<PAGE>

respect of any Collateral; (v) to defend any suit, action or proceeding brought
against Lessee with respect to any Collateral; (vi) to settle, compromise and
adjust any suit, action or proceeding described above and, in connection
therewith, to give such discharges or releases as Lender may deem appropriate;
and (vii) generally to sell, transfer, pledge, make any agreement with respect
to or otherwise deal with any of the Collateral as fully and completely as
though Lender were the absolute owner thereof for all purposes, and to do, at
Lender's option and Lessee's expense, at any time, or from time to time, all
acts and things which Lender deems necessary to protect, preserve or realize
upon the Collateral and Lender's security interest therein, in order to effect
the intent of this Security Agreement, all as fully and effectively as Lessee
might do.

     Lessee hereby ratifies all that said attorneys shall lawfully do or cause
to be done by virtue hereof. This power of attorney is a power coupled with an
interest and shall be irrevocable.

     Section 5.10 Application of Proceeds. Lender shall retain the net proceeds
                  -----------------------
of any collection, recovery, receipt, appropriation, realization or sale of the
Collateral and, after deducting all reasonable costs and expenses of every kind
incurred therein or incidental to the care and safekeeping of any or all of the
Collateral or in any way relating to the rights of Lender hereunder, including
reasonable attorneys' fees and legal expenses, apply such net proceeds to the
payment in whole or in part of the Obligations in such order as Lender may
elect. Only after applying such net proceeds and after the payment by Lender of
any other amount required by any provision of law, including Section 9-504(1)(c)
of the UCC, need Lender account for the surplus, if any, to Lessee or to
whomsoever may be lawfully entitled to the same.

                 -------
hereunder shall be in writing and shall be deemed appropriately given if given
in accordance with the requirements of the Loan Agreement.

     Section 6.2 No Waivers. No failure on the part of Lender to exercise, no
                 ----------
course of dealing with respect to, and no delay in exercising any right, power
or privilege under this Security Agreement or any document or agreement
contemplated hereby shall operate as a waiver thereof or shall any single or
partial exercise of any such right, power or privilege preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.

     Section 6.3 Compensation and Expenses of Lender. Lessee shall pay to Lender
                 -----------------------------------
from time to time upon demand, all of the fees, costs and expenses incurred by
Lender (including, without limitation, the reasonable fees and disbursements of
counsel and any amounts payable by Lender to any of its agents, whether on
account of fees, indemnities or otherwise) (i) arising in connection with the
administration, modification, amendment, waiver or termination of this Security
Agreement or any document or agreement contemplated hereby or any consent or
waiver hereunder or thereunder or (ii) incurred in connection with the
administration of this Security Agreement, or any document or agreement
contemplated hereby, or in connection with the administration, sale or other
disposition of Collateral hereunder or under any document or

                                       17

                 ----------------------
binding upon and inure to the benefit of each of the parties hereto and shall

intended or shall be construed to give any other person any right, remedy or
claim under, to or in respect of this Security Agreement or any Collateral.

     Section 6.6 Limitation of Law; Severability.
                 -------------------------------

          (a) All rights, remedies and powers provided in this Security
Agreement may be exercised only to the extent that the exercise thereof does not
violate any applicable provision of law, and all the provisions of this Security
Agreement are intended to be subject to all applicable mandatory provisions of
law which may be controlling and to be limited to the extent necessary so that
they will not render this Security Agreement invalid, unenforceable in whole or
in part, or not entitled to be recorded, registered or filed under the
provisions of any applicable law.

          (b) If any provision hereof is invalid and unenforceable in any
jurisdiction, then, to the fullest extent permitted by law, (i) the other
provisions hereof shall remain in full force and effect in such jurisdiction and
shall be liberally construed in order to carry out the intentions of the parties
hereto as nearly as may be possible; and (ii) the invalidity or unenforceability
of any provision hereof in any jurisdiction shall not affect the validity or
enforceability of such provisions in any other jurisdiction.

     Section 6.7 Governing Law. This Security Agreement shall be governed by and
                 -------------
construed in accordance with the laws of the state of New York (other than those
conflicts of laws provisions that would defer to the substantive laws of another
jurisdiction). Without in any way limiting the preceding choice of law, the
parties elect to be governed by New York law in accordance with, and are relying
(at least in part) on, Section 5-1401 of the General Obligations Law of the
State of New York.

     Section 6.8 Counterparts; Effectiveness. This Security Agreement may be

                 ---------------------
when the security interests granted hereunder have terminated and the Collateral
has been released as provided in Section 2.4, provided that the obligations of
Lessee under any of Section 6.3 shall survive any such termination.
