                   AMENDED AND RESTATED STOCK PLEDGE AGREEMENT


        THIS AMENDED AND RESTATED STOCK PLEDGE AGREEMENT (this "Agreement") is
made and given as of this 10th day of August, 2001, by CANDLEWOOD HOTEL COMPANY,
INC., a Delaware corporation (the "Pledgor"), for the benefit of HPT CW
PROPERTIES TRUST, a Maryland real estate investment trust (together with its
successors and assigns, the "Secured Party").

                              W I T N E S S E T H:

        WHEREAS, pursuant to an Amended and Restated Lease Agreement, dated as
of the date hereof (as amended from time to time, the "Amended and Restated
Lease"), the Secured Party leased to Candlewood Leasing No. 1, Inc., a Delaware
corporation (the "Tenant"), and the Tenant leased from the Secured Party certain
premises as more particularly described in and subject to and upon the terms and
conditions set forth in the Amended and Restated Lease; and

        WHEREAS, the Pledgor owns all of the outstanding shares of capital stock
of the Tenant and shall derive direct substantial benefit from the transactions
contemplated by the Amended and Restated Lease;

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

        SECTION 1. CERTAIN TERMS. Capitalized terms used and not otherwise
defined in this Agreement shall have the meanings ascribed to such terms in the
Amended and Restated Lease.

        SECTION 2. PLEDGE. The Pledgor hereby pledges to the Secured Party the
shares of capital stock of the Tenant (the "Pledged Stock") listed in Exhibit A
attached hereto (the Pledged Stock and any additional securities or collateral
pledged hereunder, collectively, the "Pledged Collateral"), and the Pledgor
hereby grants to the Secured Party a security interest in all of the Pledged
Collateral as security for the due and punctual payment and performance of the
Secured Obligations (as hereinafter defined).




                                      -1-

        SECTION 3. SECURED OBLIGATIONS. For purposes of this Agreement, the term
"Secured Obligations" shall mean the payment and performance of each and every
obligation of the Tenant to the Secured Party, under the Amended and Restated
Lease, whether now existing or hereafter arising, and including, without
limitation, payment of the Rent.

        SECTION 4. REPRESENTATIONS OF THE PLEDGOR. The Pledgor covenants that
the Pledged Stock is duly and validly pledged to the Secured Party in accordance
with law and the Pledgor shall warrant and defend the Secured Party's right,
title and security interest in and to the Pledged Stock against the claims and
demands of all persons whomsoever. The Pledgor represents and warrants to the
Secured Party that the Pledgor has good title to all the Pledged Stock, free and
clear of all claims, mortgages, pledges, liens, security interests and other
encumbrances of every nature whatsoever; that the Pledged Stock is not subject
to any restriction on transfer contained in the charter documents or by-laws of
the Tenant or in any agreement or instrument to which the Tenant or the Pledgor
are a party or by which the Tenant or the Pledgor is bound which would prohibit
or restrict the pledge of the Pledged Stock hereunder or the disposition thereof
upon default hereunder; that all of the Pledged Stock has been duly and validly
issued and is fully paid and nonassessable; and that the Pledged Stock
constitutes all of the presently issued and outstanding shares of the capital
stock of the Tenant. The Pledgor covenants and agrees that if any additional
shares of the capital stock of the Tenant are acquired by the Pledgor after the
date hereof the same shall constitute a part of the Pledged Collateral and shall
be pledged with the Secured Party as provided in Section 2 upon such
acquisition.

        SECTION 5. COVENANTS OF THE PLEDGOR. The Pledgor hereby covenants and
agrees that it shall not sell, convey or otherwise dispose of any of the Pledged
Collateral nor create, incur or permit to exist any pledge, mortgage, lien,
charge, encumbrance or any security interest whatsoever with respect to any of
the Pledged Collateral or the proceeds thereof, other than the liens on and
security interests in the Pledged Collateral created hereby. The Pledgor further
covenants and agrees that it shall not consent to or approve the issuance of any
additional shares of the capital stock of the Tenant.




                                      -2-

        SECTION 6. DISTRIBUTIONS, ETC. Upon the dissolution, winding up,
liquidation or reorganization of the Tenant, whether in bankruptcy, insolvency
or receivership proceedings or upon an assignment for the benefit of creditors
or any other marshalling of the assets and liabilities of the Tenant, if any sum
shall be paid or any property shall be distributed upon or with respect to any
of the Pledged Collateral, such sum shall be paid over to the Secured Party, to
be held as collateral security for the Secured Obligations. If any stock
dividend shall be declared on any of the Pledged Collateral, or any share of
stock or fraction thereof shall be issued pursuant to any stock split involving
any of the Pledged Collateral, or any distribution of capital (excluding cash
dividends) shall be made on any of the Pledged Collateral, or any property shall
be distributed upon or with respect to the Pledged Collateral pursuant to
recapitalization or reclassification of the capital of the Tenant, the shares or
other property so distributed shall be delivered to the Secured Party to be held
as collateral security for the Secured Obligations.

        SECTION 7. EVENT OF DEFAULT. For purposes of this Agreement, the term
"Event of Default" shall mean (a) the occurrence of an Event of Default under
the Amended and Restated Lease; (b) the failure of the Pledgor to comply with
any of its covenants or obligations under this Agreement and the continuation
thereof for a period of thirty 30 days after written notice thereof; provided,
however, that if such default is susceptible of cure but such cure cannot be
accomplished with due diligence within such period of time and if in addition
the Pledgor commences to cure or cause to be cured such default within thirty
(30) days after written notice thereof from the Secured Party and thereafter
prosecutes the curing of such default with all due diligence, such period of
time shall be extended to such period of time (not to exceed an additional
ninety (90) days in the aggregate) as may be necessary to cure such default with
all due diligence; or (c) any representation or warranty contained herein or
made by the Pledgor in connection herewith shall prove to have been false or
misleading in any material respect when made.

        SECTION 8. REMEDIES. (a) Upon the occurrence of an Event of Default, the
Secured Party may cause all or any of the Pledged Collateral to be transferred
into its name or into the name of its nominee or nominees, subject to the
provisions of the Uniform Commercial Code or other applicable law.




                                      -3-
<PAGE>

        (b) Upon the occurrence and during the continuance of an Event of
Default, the Secured Party shall be entitled to exercise the voting power with
respect to the Pledged Collateral, to receive and retain, as collateral security
for the Secured Obligations, any and all dividends or other distributions at any
time and from time to time declared or made upon any of the Pledged Collateral,
and to exercise any and all such rights of payment, conversion, exchange,
subscription or any other rights, privileges or options pertaining to the
Pledged Collateral as if it were the absolute owner thereof, including, without
limitation, all such rights under any shareholders agreement, and further
including, without limitation, the right to exchange, at its discretion, any and
all of the Pledged Collateral upon the merger, consolidation, reorganization,
recapitalization or other readjustment of the Tenant, upon the exercise of any
such right, privilege or option pertaining to the Pledged Collateral, and in
connection therewith, to deposit and deliver any and all of the Pledged
Collateral with any committee, depositary, transfer agent, registrar or other
designated agency upon such terms and conditions as the Secured Party may
determine.

        (c) Upon the occurrence and during the continuance of an Event of
Default, the Secured Party shall have all of the rights and remedies of a
secured party under the Uniform Commercial Code or other applicable law and
shall have the right to sell, resell, assign and deliver all or any of the
Pledged Collateral in one or more parcels at any exchange or broker's board or
at public or private sale. The Secured Party shall give the Pledgor at least ten
(10) days' prior written notice of the time and place of any public sale thereof
or of the time after which any private sale or any other intended disposition
thereof is to be made. Any such notice shall be deemed to meet any requirement
hereunder or under any applicable law (including the Uniform Commercial Code)
that reasonable notification be given of the time and place of such sale or
other disposition. Such notice may be given without any demand of performance or
other demand, all such demands being hereby expressly waived by the Pledgor to
the extent permitted by applicable law. All such sales shall be at such
commercially reasonable price or prices as the Secured Party shall deem best and
either for cash or on credit or for future delivery (without assuming any
responsibility for credit risk). At any such sale or sales, the Secured Party
may purchase any or all of the Pledged Collateral to be sold thereat upon such
terms as the Secured Party may deem




                                      -4-
<PAGE>

best. Upon any such sale or sales, the Pledged Collateral so purchased shall be
held by the purchaser absolutely free from any claims or rights of any kind or
nature of the Pledgor, including any equity of redemption and any similar
rights, all such equity of redemption and any similar rights being hereby
expressly waived and released by the Pledgor to the extent permitted by
applicable law. In the event any consent, approval or authorization of any
governmental agency will be necessary to effectuate any such sale or sales, the
Pledgor shall execute, and hereby agrees to cause the Tenant to execute, all
such applications or other instruments as may be required. The proceeds of any
such sale or sales, together with any other additional collateral security at
the time received and held hereunder, shall be received and applied: first, to
the payment of all costs and expenses of such sale, including attorneys' fees;
and second, to the payment of the Secured Obligations in such order of priority
as the Secured Party shall determine; and any surplus thereafter remaining shall
be paid to the Pledgor or to whomever may be legally entitled thereto
(including, if applicable, any subordinated creditor of the Pledgor).

        The Pledgor recognizes that the Secured Party may be unable to effect a
public sale of all or a part of the Pledged Collateral by reason of certain
prohibitions contained in the Securities Act of 1933, and may be compelled to
resort to one or more private sales to a restricted group of purchasers who will
be obliged to agree, among other things, to acquire such Pledged Collateral for
their own accounts, for investment and not with a view to the distribution or
resale thereof. The Pledgor agrees that private sales so made may be at prices
and upon other terms less favorable to the seller than if such Pledged
Collateral were sold at public sales, and that the Secured Party shall have no
obligation to delay sale of any such Pledged Collateral for the period of time
necessary to permit such Pledged Collateral to be registered for public sale
under the Securities Act of 1933. The Pledgor agrees that private sales made
under the foregoing circumstances may be deemed to have been made in a
commercially reasonable manner. Nothing herein shall be deemed to require the
Pledgor to effect a registration of the Pledged Collateral under the Securities
Act of 1933.

        (d) Upon the occurrence and during the continuance of any Event of
Default, the Secured Party, in its discretion, may demand, sue for and/or
collect any money or property at any time due, payable or receivable, to which
it may be entitled




                                      -5-
<PAGE>

hereunder, on account of or in exchange for any of the Pledged Collateral. Upon
the occurrence and during the continuance of any Event of Default, the Secured
Party shall further have the right, for and in the name, place and stead of the
Pledgor, to execute endorsements, assignments, or other instruments of
conveyance or transfer with respect to all or any of the Pledged Collateral.

        (e) The Secured Party shall not be obligated to do any of the acts
hereinabove authorized and in the event that the Secured Party elects to do any
such act, the Secured Party shall not be responsible to the Pledgor, other than
for gross negligence or willful misconduct.

        SECTION 9. RIGHTS OF SECURED PARTY. No course of dealing between the
Pledgor and the Secured Party nor any failure to exercise, nor any delay in
exercising, on the part of the Secured Party, any right, power or privilege
hereunder or under any of the Secured Obligations, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder or thereunder preclude any other or further exercise thereof
or the exercise of any other right, power or privilege. The rights and remedies
herein provided and provided under any of the Secured Obligations are cumulative
and are in addition to, and not exclusive of, any rights or remedies provided by
law, including, without limitation, the rights and remedies of a secured party
under the Uniform Commercial Code.

        SECTION 10. ASSIGNMENT, ETC. No waiver by the Secured Party or by any
other holder of Secured Obligations of any default shall be effective unless in
writing nor operate as a waiver of any other default or of the same default on a
future occasion. In the event of a sale or assignment by the Secured Party of
its interest under the Amended and Restated Lease, the Secured Party may assign
or transfer its rights and interest under this Agreement in whole or in part to
the purchaser or assignee of such interest, whereupon such purchaser or
purchasers shall become vested with all of the powers and rights given to the
Secured Party hereunder, and the Secured Party shall thereafter be forever
released and fully discharged from any liability or responsibility thereafter
arising hereunder with respect to the rights and interests so assigned.

        SECTION 11. DUTY OF SECURED PARTY. Beyond the exercise of reasonable
care to assure the safe custody of the Pledged




                                      -6-
<PAGE>

Collateral while held hereunder, the Secured Party shall have no duty or
liability to collect any sums due in respect thereof or to protect or preserve
rights pertaining thereto, and shall be relieved of all responsibility for the
Pledged Collateral upon surrendering the same to the Pledgor.

        SECTION 12. WAIVERS, ETC. To the extent permitted by applicable law, the
Pledgor, on its own behalf and on behalf of its successors and assigns, hereby
waives presentment, demand, payment, notice of dishonor, protest and, except as
otherwise provided herein, all other demands and notices in connection with this
Agreement or the enforcement of the rights of the Secured Party hereunder or in
connection with any Secured Obligations. The Secured Party may release,
supersede, exchange or modify any collateral security it may from time to time
hold and release, surrender or modify the liability of any third party without
giving notice hereunder to the Pledgor. The Secured Party shall be under no duty
to exhaust its rights against any such collateral security or any such third
party before realizing on the Pledged Collateral. Such modifications, changes,
renewals, releases or other actions shall in no way affect the Pledgor's
obligations hereunder.

        The Pledgor further waives any right it may have under the Constitution
of The Commonwealth of Massachusetts (or under the constitution of any other
state in which the any of the Pledged Collateral may be located), or under the
Constitution of the United States of America, to notice (except for notice
specifically required hereby) or to a judicial hearing prior to the exercise of
any right or remedy provided by this Agreement to the Secured Party, and waives
its rights, if any, to set aside or invalidate any sale duly consummated in
accordance with the foregoing provisions hereof on the grounds (if such be the
case) that the sale was consummated without a prior judicial hearing. THE
PLEDGOR'S WAIVERS UNDER THIS SECTION 12 HAVE BEEN MADE VOLUNTARILY,
INTELLIGENTLY AND KNOWINGLY AND AFTER THE PLEDGOR HAS BEEN APPRISED AND
COUNSELED BY ITS ATTORNEYS AS TO THE NATURE THEREOF AND ITS POSSIBLE ALTERNATIVE
RIGHTS.

        SECTION 13. FURTHER ASSURANCES AS TO COLLATERAL; ATTORNEY-IN-FACT. From
time to time hereafter, the Pledgor shall execute and deliver, or will cause to
be executed and delivered, such additional instruments, certificates or
documents (including without limitation financing statements, renewal
statements, collateral assignments and other security




                                      -7-
<PAGE>

documents), and shall take all such actions, as the Secured Party may reasonably
request, for the purposes of implementing or effectuating the provisions of this
Agreement or of more fully perfecting or renewing the Secured Party's rights
with respect to the Pledged Collateral (or with respect to any additions thereto
or replacements or proceeds thereof or with respect to any other property or
assets hereafter acquired by the Pledgor which may be deemed to be a part of the
Pledged Collateral) pursuant hereto and thereto. The Secured Party is hereby
appointed the attorney-in-fact, with full power of substitution, of the Pledgor
for the purpose of carrying out the provisions of this Agreement and taking any
action, including, without limitation, executing, delivering and filing
applications, certificates, instruments and other documents and papers with
governmental authorities, and executing any instruments, including without
limitation, assignments, conveyances and transfers which are required to be
taken or executed by the Pledgor under this Agreement, on its behalf and in its
name which appointment is coupled with an interest, is irrevocable and durable
and shall survive the subsequent dissolution, disability or incapacity of the
Pledgor; provided, however, that the Secured Party shall not be entitled to take
any action required of the Pledgor under this Agreement unless the Secured Party
has made written demand on the Pledgor to take such action and the Pledgor,
having been afforded a reasonable time to take such action, fails to do so.

        SECTION 14. NOTICES. (a) Any and all notices, demands, consents,
approvals, offers, elections and other communications required or permitted
under this Agreement shall be deemed adequately given if in writing and the same
shall be delivered either in hand, by telecopier with written acknowledgment of
receipt, or by mail or Federal Express or similar expedited commercial carrier,
addressed to the recipient of the notice, postpaid and registered or certified
with return receipt requested (if by mail), or with all freight charges prepaid

        SECTION 17. RESTRICTIONS ON TRANSFER. To the extent that any

<PAGE>

with the laws of The Commonwealth of Massachusetts applicable to contracts
between residents of Massachusetts which are to be performed entirely within

delivered; or (ii) where any payment or other performance required by any such
instrument is made or required to be made; or (iii) where any breach of any
provision of any such instrument occurs, or any cause of action otherwise
