agrees that all such waivers and agreements, and all other agreements of
Assignor in any Assumed Agreement shall, with respect to all Assumed
Obligations, apply to and be enforceable against Assignee to the same extent as
if Assignee were a party to each Assumed Agreement.

        (c)     The Assignee Reimbursement Obligations (and any interest

Assignee hereunder.

Assignor a demand for payment or performance by Assignor of any Assumed
Obligation (a "Demand"), and (ii) Assignee shall have notified Assignor that
Assignee and/or Company is disputing the amount or existence of the obligation
as to which Demand has been made, then so long as Assignee and Company are
diligently and in good faith disputing such obligation, Assignor shall refrain
from paying or otherwise performing the alleged obligation, provided that (w) if
Assignor, in its sole discretion, so requests, Assignee, at its expense, shall
make arrangements satisfactory to Assignor with the Counterparty and a third
party acceptable to Assignor, to hold in escrow pending resolution of the
dispute any amount tendered by Assignor pursuant to such Demand; and (x)
Assignee shall indemnify, defend and hold harmless Assignor and its directors,
officers, employees, Affiliates, agents and assigns in accordance with Article X

that, notwithstanding the foregoing,

                                       8
<PAGE>

Assignor may at any time elect to pay the applicable Assumed Obligation while
Company or Assignee is disputing an obligation, in which event Assignee shall

        8.      COLLATERAL EVENTS. If any of the following conditions or events
(each, a "Collateral Event") shall occur:

        (a)     Assignee shall fail to pay any amount when due under Section
3(a) or Section 7 (b) hereof, and such failure continues for 10 Business Days;
or

        (b)     Any demand for payment or other performance under or in respect
of any Assumed Obligation shall be made on Assignor, unless (i) such demand
shall be rescinded within 15 Business Days thereof, or (ii) the associated
obligation shall have been paid or performed in full by Assignee within 15
Business Days of notice thereof by Assignor to Assignee unless Assignee and/or
Company is diligently and in good faith disputing the applicable obligation (and
Assignee has given Assignor notice thereof and is otherwise complying with
Section 7(b) hereof); or

        (c)     Assignee, Company or MCC (or any transferee pursuant to Section
5.18 of the Purchase Agreement) shall fail to perform or comply with Section 6
(c) hereof, Section 5.7 (b) of the Purchase Agreement or the second sentence of
Section 5.7(a) of the Purchase Agreement; or Company or any Company Subsidiary
(or any transferee pursuant to Section 5.18 of the Purchase Agreement) shall
fail to pay any amount when due under any Underlying Agreement, and, unless
Assignee and/or Company is diligently and in good faith disputing such payment
obligation, and such failure continues for 15 Business Days; or

        (d)     Assignee shall fail to pay when due any principal of or interest
on any indebtedness with an aggregate principal amount in excess of $10,000,000
beyond any grace period provided therefor; or

        (e)     Any Insolvency Event (as defined below) shall occur; or

        (f)     The implied senior unsecured debt rating of Assignee shall be
"B-" or less by Standard and Poors Corporation, or "B1" or less by Moody's

<PAGE>

then, in addition to any other remedy available to Assignor at law or in equity,
upon the request of Assignor (which request shall, in the case of a Collateral
Event under Section 8(e), be deemed automatically to have been made, without
presentment, demand, protest or other requirement of any kind, all of which are
hereby waived), as collateral security for the Assignee Reimbursement
Obligations and the Insurance Retention Obligations, Assignee shall promptly (x)
deposit into a cash collateral account for the benefit of Assignor, pursuant to
documentation in form and substance satisfactory to Assignor, or, at Assignor's
election, (y) deliver to Assignor a letter of credit in form and substance, and
from an institution, satisfactory to Assignor, in either case, in an aggregate
amount equal to the sum of (i) the aggregate amount of rent payable for one year
under each of the Leases, (ii) an amount equal to 10% of the outstanding
Lifecare Obligations, and (iii) an amount equal to the projected ultimate loss
on the $1million per occurrence self-insured retentions for Buyer Patient Injury
Claims resulting from occurrences on or prior to the Closing Date (as determined
by an independent actuary at the expense of Assignee), less all amounts
previously paid by Assignee in respect of such losses (any such cash collateral

        liquidator, sequestrator, trustee, custodian or other officer having
        similar powers over Assignee or Company or over all or a substantial

an amount equal to all amounts so paid and all other costs or expenses so
incurred no later than two (2) Business Days after receipt from Marriott Parent

time by the specified Person.

        4.      OBLIGATIONS ABSOLUTE. The obligations of each Assignee to
Marriott Parent under this Agreement shall be absolute and unconditional, under
any and all circumstances, and shall not be diminished, discharged or affected
by any circumstance, act or omission whatsoever, including without limitation
any of the following, whether known or unknown to either of the Assignors:

                (a)     the invalidity or unenforceability of, or any defect in,

right which any Assignee, any of its Affiliates, either Assignor, or any
beneficiary of or party to a Lifecare Bond or Continuing Care Agreement, on the
one hand, may have at any time against either Assignor, any beneficiary of or
party to a Lifecare Bond or Continuing Care Agreement or any other

                                       5
<PAGE>

Person, on the other hand, whether in connection with this Agreement, any of the
Assumed Obligations, the Lifecare Bonds or the Continuing Care Agreements or the
transactions referred to herein or therein or in connection with any unrelated
transaction;

                (f)     any certificate, draft, demand or other document

clause (c) above or any other Person;

                (i)     any consequence of compliance with any applicable

beneficiary of or party to a Lifecare Bond or Continuing Care Agreement, done or
omitted pursuant to an order of any court; or

                (k)     any other circumstance or happening whatsoever, whether
or not similar to any of the foregoing, including, without limitation, any other
circumstance that might otherwise constitute a defense available to, or a
discharge of, any Assignee, except for circumstances resulting directly from the
gross negligence or willful misconduct of Marriott Parent or, only to the extent
occurring prior to the date hereof, MCC.

        Each Assignee acknowledges and agrees that it will derive substantial
direct and indirect benefits by reason of Marriott Parent continuing to be a
party to the Lifecare Undertakings, and that all obligations of Assignees to
Marriott Parent hereunder shall be joint and several irrespective of whether any
applicable Assumed Obligation relates to the Fairfax or the Quadrangle. Neither
the joint and several liability of, nor the liens granted to Marriott Parent
under the Mortgages by, any Assignee shall be impaired or released by (i) the
failure of either Assignor to assert any claim or demand or to exercise or
enforce any right, power or remedy against any Assignee or any of its
Affiliates, any other Person or otherwise; (ii) any extension or renewal for any
period (whether or not longer than the original period) of any Lifecare Bonds or
Continuing Care Agreements or the release or compromise of any obligation of any
Person with respect thereto; (iii) the surrender, release or exchange of all or
any part of any property securing payment, performance and/or observance of any
of the Parent Reimbursement Obligations or the compromise or extension or
renewal for any period (whether or not longer than the original period) of any
obligations of any Person with respect to any such property; or (iv) any other
act,

                                       6
<PAGE>

matter or thing that would or might, in the absence of this provision, operate
to release, discharge or otherwise prejudicially affect the obligations of each
Assignee.

                                       7
<PAGE>

        5.      ADDITIONAL AGREEMENTS IN RESPECT OF LIFECARE UNDERTAKINGS.

                (a)     Solely with respect to Persons who, as of the date
hereof, (i) hold a Lifecare Bond issued in respect of a Facility, as set forth
on Schedules 1 and 2 hereto, or (ii) are resident at a Facility and party to a
Continuing Care Agreement (collectively, "Current Lifecare Beneficiaries"), and
without limiting the obligations of Assignees and MCC hereunder and under the
Operating Agreements, Marriott Parent shall remain secondarily liable to MCC for
financial obligations arising under the Lifecare Undertakings; provided that
Assignees, jointly and severally, shall be primarily liable with respect to such
Current Lifecare Beneficiaries, and MCC (and, if applicable, Operating
Assignees) shall at all times proceed first against CNL Parent (or an Operating
Assignee) for the performance of all obligations under the Lifecare Undertakings
or otherwise in respect of the Lifecare Bonds and Continuing Care Agreements,
and shall pursue and exhaust all remedies available against Assignees prior to
seeking any payment or performance by Marriott Parent under any Lifecare
Undertaking or otherwise in respect of the Lifecare Bonds and Continuing Care
Agreements in favor of Current Lifecare Beneficiaries.

                (b)     Except as set forth in Section 5(a) in respect of
Current Lifecare Beneficiaries, MCC and the Assignees hereby irrevocably and
completely discharge and release Marriott Parent and its Affiliates from any
liability under any Lifecare Undertaking or otherwise in respect of Lifecare
Bonds and Continuing Care Agreements.

                (c)     Assignees and MCC hereby waive any applicable principles
or provisions of Law, statutory or otherwise, or contract which are or might be
in conflict with the terms of this Section 5.

                (d)     Without limiting the obligations of Assignees hereunder,
(i) nothing herein purports or is intended to release MCC from its obligations
under any Continuing Care Agreement, and (ii) solely as between MCC and any
Person that holds a Lifecare Bond, nothing herein purports to or is intended to
release MCC from its obligations to such Person under the applicable Lifecare
Bond.

        6.      COVENANTS AND ACKNOWLEDGEMENTS OF ASSIGNEES AND MCC.

                (a)     Neither MCC nor any Assignee shall, or shall cause or
permit any of its Subsidiaries or MCC to (i) directly or indirectly assign or
otherwise transfer (other than to an Affiliate of CNL Parent) any of its direct
or indirect obligations to a Current Lifecare Beneficiary (or, in the case of an
Operating Assignee, its obligations to MCC) under or in respect of any Lifecare
Bond or Continuing Care Agreement (each such obligation, an "Underlying Lifecare
Obligation"), (ii) cause or permit the term of any Underlying Lifecare
Obligation to be extended beyond the term in effect on the Closing Date, or
(iii) enter into or agree to any amendment or modification to the terms of any
Underlying Lifecare Obligation, unless, in any such case, prior to the
effectiveness thereof, Marriott Parent and its Affiliates shall be
unconditionally released, in a manner reasonably satisfactory to Marriott Parent
(which shall, without limitation, require an acknowledgement from the applicable
Current Lifecare Beneficiary) from all obligations to such Current Lifecare
Beneficiary; provided that MCC or CNL Parent may assign or otherwise transfer
(directly or indirectly) any Underlying Lifecare Obligation so long as (x) prior
to such assignment or transfer, MCC or CNL Parent shall notify Marriott Parent
thereof specifying the

                                       8
<PAGE>

Underlying Lifecare Obligations transferred and the name of the transferee and
certifying that the other conditions set forth below have been satisfied (if
applicable), (y) the transferee shall be at least as creditworthy as CNL Parent
or MCC, as applicable and (z) the transferee shall have delivered a letter
agreement to Marriott Parent pursuant to which it agrees to be bound by the
restrictions set forth in this Section 6(a) for the benefit of Marriott Parent;
and provided further that no such transfer shall alter or effect the obligations
of Assignees hereunder. MCC and each Assignee shall promptly notify Marriott
Parent of any default or alleged default in payment of any amount due to a
Current Lifecare Beneficiary under any Lifecare Bond, which default or alleged
default could reasonably be expected to lead to a demand for payment by Marriott
Parent under Section 5(a).

                (b)     MCC shall (or shall cause its Affiliate to) give prompt
notice to Marriott Parent and CNL Parent of any demand for payment of an
Outstanding Bond, and any other demand in respect of a Continuing Care Agreement
or Lifecare Bond if, in any such case, such demand could reasonably be expected
to give rise to an obligation under any Parent Lifecare Agreement.

                (c)     Assignees acknowledge and agree that CNL Parent and its
Subsidiaries are not obtaining any rights or licenses with respect to any name,
mark, logo, trade dress or design owned by Marriott Parent or its Affiliates,
including the word mark "Marriott" (the "Marriott Word Mark"), the name and mark
"Marriott International, Inc.", the "M" logo (a copy of which is attached hereto
as Schedule (4)) or any composite or other name or mark containing "Marriott",
or any name, mark, logo or design that is similar to any of the foregoing in
appearance, sound or commercial impression (the "Marriott Parent Marks").
Assignees shall, and shall cause their respective Subsidiaries and any manager
of either Facility, to cease any and all use of the Marriott Parent Marks as
soon as practicable after the Closing Date, but not later than 60 days after the
Closing Date; provided, however, that with respect to stationery, contracts,
purchase orders, agreements and other business forms and writings (including
without limitation, Lifecare Bonds and Continuing Care Agreements) which could
result after the Closing Date in a legal commitment of Marriott Parent or any of
its Subsidiaries, Assignees shall, and shall cause their respective Subsidiaries
and any manager of either Facility, to cease within 10 Business Days after the
Closing Date any use of the Parent Marks; provided further that, from and after
the Closing Date, MCC shall comply with the provisions of Section 5.7 (f) of the
Stock Purchase Agreement. Within 10 Business Days after the Closing Date,
Assignees shall notify, or cause the manager of the Facilities to notify, in
writing, all residents at the Facilities that the Facilities have been acquired
from Sellers by Buyer, and that CNL Parent will, from and after the Closing
Date, ensure that the Facilities have all financial and other support that may
be required to ensure compliance with all obligations under the Lifecare Bonds
and Continuing Care Agreements.

        7.      COVENANT OF ASSIGNOR. Marriott Parent shall give written notice
to CNL Parent promptly upon receipt of any demand on Marriott Parent for payment
or performance of any Assumed Parent Obligation; provided that no failure to
give any such notice shall alter or affect the obligations of Assignees
hereunder.

        8.      EVENTS OF DEFAULT. If any of the following conditions or events
(each, an "Event of Default") shall occur:

                                       9
<PAGE>

                (a)     Any Assignee shall fail to pay Marriott Parent any
amount due under Section 3(a)(ii) hereof, and such failure continues for 10
Business Days; or

                (b)     Any Assignee shall fail to pay MCC any amount due under
Section 3(a)(i) hereof, and such failure continues for 10 Business Days; or

                (c)     Any demand shall be made to Marriott Parent for payment
or other performance under or in respect of any Assumed Obligation, any Lifecare
Bond or Continuing Care Agreements and shall not either be (i) rescinded within
15 Business Days thereof or (ii) paid or performed in full by Assignees within
15 Business Days of notice thereof by Marriott Parent to Assignees; or

                (d)     Any Assignee or MCC shall fail to perform or comply with
its obligations under Section 6 hereof and such failure shall continue for 15
Business Days; or any Underlying Lifecare Obligation shall otherwise be
transferred (directly or indirectly) to any Person other than CNL Parent or an
Affiliate thereof, unless the conditions set forth in Section 6(a) have been
satisfied in connection with such transfer); or

                (e)     Any Assignee or MCC shall fail to perform or comply with
any of its obligations under this Agreement which failure is not already
addressed in Section 8(a) though (d) hereof and such failure shall continue for
10 Business Days; or

                (f)     Any "Event of Default" as defined in either Mortgage
shall occur and be continuing; or

                (g)     Any Insolvency Event (as defined below) shall occur;

                then, in addition to any other remedy available to Marriott
Parent at law or in equity, in the case of any event described in clause (g),
the maximum amount that may at any time become due under or in respect of the
Assumed Parent Obligations (the "Maximum Amount") shall automatically become
immediately due and payable, without presentment, demand, protest or other
requirements of any kind, all of which are hereby waived; and, if any other
Event of Default shall have occurred and be continuing, Marriott Parent may, by
written notice to CNL Parent declare all or any portion of the Maximum Amount
due and payable, and the same shall become immediately payable without
presentment, demand, protest or other requirements of any kind, all of which are
hereby waived. If any Event of Default shall have occurred and be continuing, in
addition to and not in limitation of any other rights available to Marriott
Parent at law or in equity, Marriott Parent may exercise all rights and remedies
provided for in either.

        "INSOLVENCY EVENT" shall mean:

                        (i)     A court having jurisdiction in the premises
shall enter a decree or order for relief in respect of CNL Parent or either
Operating Assignee in an involuntary case under any applicable bankruptcy,
insolvency or similar law now or hereafter in effect, which decree or order is
not stayed; or

                                       10
<PAGE>

                        (ii)    An involuntary case shall be commenced against
CNL Parent or either Operating Assignee under any applicable bankruptcy,
insolvency or similar law now or thereafter in effect; or a decree or order of a
court having jurisdiction in the premises for the appointment of a receiver,
liquidator, sequestrator, trustee, custodian or other officer having similar
powers over CNL Parent or either Operating Assignee or over all or a substantial
part of its respective property, shall have been entered; or there shall have
occurred the involuntary appointment of an interim receiver, trustee or other
custodian of CNL Parent or any of the Operating Assignees for all or a
substantial part of its property; or a warrant of attachment, execution or
similar process shall have been issued against any substantial part of the
property of CNL Parent or any of the Operating Assignees and any such event
described in this clause (ii) shall continue for 60 days unless dismissed,
bonded or discharged; or

                        (iii)   CNL Parent or either Operating Assignee shall
have an order for relief entered with respect to it or commence a voluntary case
under any applicable bankruptcy, insolvency or similar law now or hereafter in
effect, or shall consent to the entry of an order for relief in an involuntary
case, or to the conversion of an involuntary case to a voluntary case, under any
such law, or shall consent to the appointment of or taking possession by a
receiver, trustee or other custodian for all or a substantial part of its
property; or CNL Parent or either Operating Assignee shall make any assignment
for the benefit of creditors; or

                        (iv)    CNL Parent or either Operating Assignee shall be
unable, or shall fail generally, or shall admit in writing its inability, to pay
its debts as such debts become due; or the Board of Directors of CNL Parent (or
any committee thereof) shall adopt any resolution or otherwise authorize any
action to approve any of the actions referred to in clause (iii) above or this
clause (iv).

        For the avoidance of doubt, nothing in this Section 8, including any
provision for notice and cure, and no exercise or waiver by Marriott Parent of
any right or remedy under this Section 8, shall alter or affect (i) the
obligation of Assignees to pay any amount due under and in accordance with
Section 3 hereof or (ii) any other right or remedy of Marriott Parent and its
Affiliates hereunder, under the Mortgages or under the Real Estate Purchase
Agreement.

9.              FURTHER ASSURANCES. Each party hereto shall promptly execute,
acknowledge and deliver, and shall cause its Affiliates to execute, acknowledge
and deliver, to the other parties hereto any assurances, documents, instruments
or conveyances reasonably requested by any party hereto, or necessary for the

implied, is intended to confer upon or give any Person other than the parties
hereto any rights or remedies of any nature under or by reason of this
Agreement.

                (c)     Severability. If any provision of this Agreement shall
be held or deemed to be, or shall in fact be, invalid, inoperative or
unenforceable as applied to any particular case in any jurisdiction or
jurisdictions, or in all jurisdictions or in all cases, because of the conflict
of any provision with any constitution or statute or rule of public policy or
for any other reason, such circumstance shall not have the effect of rendering
the provision or provisions in question invalid, inoperative or unenforceable in
any other jurisdiction or in any other case or circumstance or of rendering any
other provision or provisions herein contained invalid, inoperative or
unenforceable to the extent that such other provisions are not themselves
actually in conflict with such constitution, statute or rule of public policy,
but this Agreement shall be reformed and construed in any such jurisdiction or
case as if such invalid, inoperative or unenforceable provision had never been
contained herein and such provision reformed so that it would be valid,
operative and enforceable to the maximum extent permitted in such jurisdiction
or in such case.

                (d)     Section and Other Headings. The headings contained in

                (h)     Waivers, Etc. Any waiver of any term or condition of
this Agreement, or of the breach of any covenant, representation or warranty
contained herein, in any one instance, shall not operate as or be deemed to be
or construed as a further or continuing waiver of any other breach of such term,
condition, covenant, representation or warranty or any other term, condition,
